This application claims priority to U.S. provisional Patent Application Ser. No. 62/951,563 filed Dec. 20, 2019, the entire contents of which are incorporated herein by reference.
FIELD OF THE DISCLOSUREThe present disclosure relates generally to equipment used for vaporizing materials to emit a vapor for inhalation, and, more particularly to portable vaporizers for personal use.
BACKGROUNDVaporizer apparatuses may heat materials to create a vapor containing one or more desired extracted ingredients. Materials that may be vaporized include, but are not limited to, dried plant material such as herbs, liquid-based compositions such as oils, and wax-based compositions. Such materials may be referred to as “vaping materials” herein. The vapor generated from such materials can then be delivered to a user by inhalation during a “vaping” session.
Portable vaporizer apparatuses for personal use may be assembled from basic parts such as a mouthpiece, a vaporizing chamber for holding a material for vaporizing, a heater, a battery, etc. When the material for vaporizing is depleted, the vaporizer apparatus may be refilled. However, repeated refilling of the vaporizer apparatus may require that a user must assemble and disassemble these various parts over and over again, which can result in parts being lost. In addition, the mouthpiece may be exposed when the vaporizer apparatus is not in use between “vaping” sessions. This can be unhygienic for a user to position his or her mouth on the mouthpiece during a subsequent “vaping” session and can possibly lead to the unintentional inhalation of materials that may have fallen into the mouthpiece.

Though not illustrated in
The head 104 also includes a Printed Circuit Board Assembly (PCBA) 144 operably connected to the second electrical connector 115. The second electrical connector 115 is coupled to the PCBA 144 in this embodiment. The PCBA may attach to the closure member 136 and forms an interface between the second electrical connector 115 and the cartridge 134. The cartridge 134 may include electrical contacts (not shown) that operably couple to the PCBA 144 when the cartridge 134 is held in the head 104. The PCBA 144 may include circuitry to activate and/or control vaporization in the first and second vaporizing chambers 152a and 152b (
The closure member 136 has an inner face 147 with an upstanding ridge 149 thereon. The upstanding ridge 149 extends about the opening 137. The second electrical connector 115 is received in the opening 137. The closure member 136 also includes first and second cantilevers 148a and 148b that engage the core section 130 to secure the closure member 136 to the core section 130. Embodiments are not limited to this particular arrangement of the closure member 136, the PCBA 144 or the second electrical connector 115. Any suitable arrangement for coupling the cartridge 134 to receive power and/or signaling from the body 102 may be used.
The head 104 may also be configured to receive two separate cartridges (in place of the dual cartridge 134 shown), each having a respective reservoir storing a respective material for vaporizing. The two separate cartridges may each further include a respective vaporizing chamber and respective heating element for vaporizing material in the corresponding vaporizing chamber.
The head 104 releasably engages the front end 103 of the body 102 for both the “operational” and “non-operational” positions. The head 104 is reversible such that the “operational” position of the head 104 is axially reversed relative to the “non-operational” position, where the term “axially” refers to a longitudinal axis of the vaporizer apparatus 100. In the operational position (

The forward position of the inner body portion 111 may be a temporary position used for removing the head 104. The vaporizer apparatus 100 may comprise one or more biasing elements that bias the inner body portion 111 toward the rearward position. The one or more biasing elements may include one or more springs and/or magnets. For example, one or more magnets may be positioned in the inner body portion 111 and one or more metal pieces may be positioned in the outer housing 112 (or vice versa). The one or more magnets and the one or more metal pieces may be positioned to magnetically attract and be aligned when the inner body portion 111 is in the rearward position.
Once the head 104 is removed from the body 102, the head 104 may be axially reversed to be reinserted into the docking bay 107 (
As noted above, the cartridge 134 in this example is a dual-cartridge that includes a first reservoir 150a and a second reservoir 150b. The first reservoir 150a may hold a first material to be vaporized to form a first vapor. The second reservoir 150b may hold a second material to be vaporized to form a second vapor. The first and second reservoirs 150a and 150b are configured to hold liquid materials such as first and second oil-based compositions in this example. However, the reservoirs 150a and 150b are shown by way of example, and the disclosure is not limited to any particular type of vaping material or material storage method.
The first and second reservoirs 150a and 150b may each, for example, have capacity to store at least 0.25 ml of oil or other fluid for vaporizing. In some embodiments, each of the first and second reservoirs may have a storage capacity of 0.5 ml or more. In some embodiments, the capacity of each reservoir may be 1 ml or more. Embodiments are not limited to any particular capacity.
The first and second materials held in the first and second reservoirs 150a and 150b may be two different materials have different compositions and properties. For example, the first material in the first reservoir 150a may be a first oil-based composition and the second material in the second reservoir 150b may be a second, different oil-based composition. For example, the first oil-based composition may contain a first one or more psychoactive compounds, while the second oil-based composition may be substantially or completely non-psychoactive. The first and second reservoirs 150a and 150b may become depleted and may be refilled with the same or different materials.
The cartridge 134 further includes a first vaporizing chamber 152a for vaporizing the first material from the first reservoir 150a and a second vaporizing chamber 152b for vaporizing the second material from the second reservoir 150b. Each vaporizing chamber 152a and 152b receives the respective material from the corresponding reservoir 150a or 150b.
The materials may be communicated to the vaporizing chamber 152a and 152b by a wick or any other suitable method. In other embodiments, such as dry herb ovens, the material storage reservoir or compartment may also function as the vaporizing chamber.
The cartridge 134 further comprises first and second heating elements 154a and 154b operational to heat and vaporize the materials in the first and second vaporizing chambers 152a and 152b respectively. In this embodiment, the first material in the in the first reservoir 150a flows to the first vaporizing chamber 152a via fluid path 166a. The fluid path 166a may, for example, comprise a wick (not shown) that transports the material to the heating element 154a. However, embodiments are not limited to the use of wicks, and other mechanisms may be used to transport the first material. The first heating element 154a is operable to vaporize the first material to produce the first vapor. The second material in the in the second reservoir 150b flows to the second vaporizing chamber 152b via fluid path 166b. The fluid path 166b may, for example, comprise a wick (not shown). The second heating element 154b is operable to vaporize the first material to produce the second vapor.
In other embodiments, rather than two sets of vaporizing chambers, heating elements and reservoirs, the cartridge 134 may instead include a single reservoir, a single vaporizing chamber, and/or a single heating element. More than two sets of vaporizing chambers, heating elements and reservoirs may also be used. In still other embodiments, a single vaporizing chamber and/or a single heating element may be used to vaporize a mix of two or more materials received from two or more reservoirs. In still other embodiments, the cartridge 134 may contain the reservoirs 150a and 150b with one or more vaporizing chambers and heating elements being within the head 104 but external to the cartridge 134.
The vaporizer apparatus 100 further includes an airflow system 155 comprising at least one airflow path to carry the first and second vapors generated in the first and second vaporizing chambers 152a and 152b to the mouthpiece portion 106. The airflow system 155 comprises first vapor airflow path 168a, second vapor airflow path 168b, and mixed airflow path 170. The first vapor flows out from the first vaporizing chamber 152a into the first vapor airflow path 168a. The second vapor flows out from the second vaporizing chamber 152b into the second vapor airflow path 168b. The first and second airflow paths 168a and 168b extend from the cartridge 134, into the mouthpiece portion 106 where they converge into the mixed airflow path 170. The mixed airflow path 170 exits from the suction opening 108 such that a mix of the first and second vapors may be inhaled by a user though the mouthpiece portion 106. In other embodiments, the first and second airflow paths 168a and 168b may not converge, but may rather extend to separate suction openings in the mouthpiece.
For each airflow path 168a and 168b, an air flow outlet 146a or 146b of the cartridge 134 may align with a corresponding airflow inlet 172a or 172b of the mouthpiece portion 106 when the cartridge 134 is received in the head 104. It will be appreciated that various structures may be used to provide such airflow paths.
The vaporizer apparatus 100 in this example further includes airflow intake paths 174a and 174b that are in fluid communication with the outside environment and the vaporizing chambers 152a and 152b. The airflow intake paths 174a and 174b supply air from the outside environment to the vaporizing chambers 152a and 152b when a user inhales. The air mixes with and carries the corresponding first and second vapors. The airflow intake paths 174a and 174b extend from the vaporizing chambers 152a and 152b, and through a portion of the body 102. Air inlets 175a and 175b, such as air holes, in the body allow for air to enter the airflow intake paths 174a and 174b.
In this example, the vaporizer apparatus 100 comprises a processor 156 and a memory 158 operably connected to the processor 156. The memory 158 stores processor-executable instructions thereon that, when executed by the processor 156, cause the processor 156 to implement the various control functionality described herein. The vaporizer apparatus 100 in this embodiment may include a user interface 160 comprising one or more input and/or output elements (e.g. button 118). Optionally, the vaporizer apparatus 100 further comprises a clock 176 and/or a location module 178. The location module 178 obtains current location information and may be a GPS module, for example. In some embodiments, the location information may be retrieved via a wireless or wired connection to a smart phone (not shown). The smart phone may include the GPS module or other means of retrieving location information over a network. The processor 156, memory 158, user interface 160, clock 176 and location module 178 are optionally located within the body 102.
The vaporizer apparatus 100 optionally controls the flow of the first and second vapors. For example, the processor 156 may activate flow of the first vapor, but stop flow of the second vapor. The processor 156 may activate flow of both the first and second vapors and/or control a ratio of the first vapor to the second vapor. For example, the processor 156 may control the vapor flows such that the first vapor is between 0% and 100% of the total vapor flowing through the mouthpiece. Optionally, the percentage of the first vapor may be set at 25%, 50% or 75% (or other intermediate values). Thus, a user may customize the balance of the first and second vapors depending on their current wants, the current environment, etc.
The head 104 optionally includes the PCBA 144 that is operatively connected to the body 102 when the head 104 is in the operational position. The PCBA 144 may receive power, data, and/or control signals from the body 102, and the PCBA 144 may provide data and/or data to the body 102. The PCBA 144 may, for example, direct power to the heating elements 154a and 154b in accordance with control signalling received from the processor 156 of the body 102. The electrical power provided to the heating elements 154a and 154b may have a current, voltage, pulse rate, and/or duration as a function of the control signalling received from the processor 156. The temperatures of the first and second vaporizing chambers 152a and 152b may independently controlled.
In some embodiments, the PCBA 144 may comprise a second processor and/or a second memory. In other embodiments, the PCBA 144 may be in the body 102 rather than the head 104. In still other embodiments, the PCBA 144 may be omitted and the functionality of the PCBA 144 described above may be performed by the processor 156 in the body 102. The PCBA 144 is only an example physical implementation of circuitry or logic that may perform the functions described above.
The user interface 160 may comprise one or more buttons (such as the button 118 in
The LEDs 163a to 163e are positioned on the inner body portion 111 such that they are visible through the slot 114 in the outer housing 112 when the inner body portion 111 is in the rearward position.
Turning again to
The first reservoir 150a, the first vaporizing chamber 152a and the first heating element 154a may collectively be considered a first cartridge portion 135a or “pod” of the dual cartridge 134. The second reservoir 150b, the second vaporizing chamber 152b and the second heating element 154b may collectively be considered a second cartridge portion 135b or “pod” of the dual cartridge 134. As also noted above, in other embodiments, rather than a single dual-cartridge structure, two separate cartridges, each comprising a respective reservoir, vaporizing chamber and/or heating element, may be received in the head 104.
A user may select a desired mode of operation using the user interface 160. The mode of operation may be a vapor mix ratio. For example, a user may press a button (e.g. button 118 shown in
In some embodiments, the power level provided to the heating elements 154a and 154b may vary as a function of the selected mix ratio. For example, for a 50/50 mix ratio, the wattage provided to each of the heating elements 154a and 154b may be the same (e.g. high power for both, or medium power for both). For a 75/25 mix ratio, the wattage may be high for the first heating element 154a and low for the second heating element 154b. In this context, high may be 100% max power and low may be 50% max power. However, the exact relative powers and power ratios may vary and may depend on the materials being vaporized in the first and second vaporizing chambers 152a and 152b. For a 100/0 mix ratio, the output wattage may be 100% wattage for the first heating element 154a and 0% for the second heating element 154b.
As yet another option, timing of the activation of the heating elements 154a and 154b may be a function of the desired mix ratio. The duration for which the heating elements 154a and 154b are activated to vaporize material may be referred to as a “burn time”. The burn time duration may, for example, be based on an expected (e.g. typical) inhale time of a user. For example, it may be assumed that the user will typically inhale for two seconds. For a 50/50 mix ratio (i.e. 50%), the burn times for both vaporizing chambers 152a and 152b may be the same. For example, both vaporizing chambers 152a and 152b may burn for approximately two seconds. For a 75/25 mix ratio (i.e. 75%), the burn time of the second vaporizing chamber 152b may be reduced. As an example, the first vaporizing chamber may burn for approximately two seconds and the second vaporizing chamber may burn for approximately 0.5 seconds. For a 100/0 mix ratio (i.e. 100%), the burn time for the first vaporizing chamber 152a may be approximately two seconds, and the burn time for the second vaporizing chamber 152b may be zero. The burn times described above are only examples, and other different relative burn times may be used in other implementations.
As another option, the heating elements 154a and 154b may be controlled to individually and selectively generate vapor at variable rates to provide the selected vapor mix. The heating elements 154a and 154b may be controlled by the processor 156 to vary the rate of vapor production. For example, power to each of the heating elements 154a and 154b may be “pulsed” at variable rates. For each heating element 154a and 154b, the respective “pulse” rate may determine the rate of vapor production. For example, a faster pulse rate may produce a higher flow of vapor than a slower pulse rate. The total airflow through the paths 168a and 168b may be approximately the same (or similar), but the density of vapor in the air that flows through such paths may vary by this method.
For example, if the selected ratio is 100% the first vapor and 0% the second vapor, the heating element 154a may be pulsed to generate vapor while the second heating element 154b is not pulsed at all. For a 50/50 mix ratio (i.e. 50%), each of the heating elements 154a and 154b may be pulsed at the same rate(s). For a ratio that is 25% the first vapor and 75% the second vapor, the first heating element 154a may be pulsed at a slower rate than the second heating element 154b.
The specific pulse rate(s) of the heating elements 154a and 154b may also vary dependent on other factors, such as vaporizing chamber temperature, airflow rate (e.g. when a user is currently inhaling vs. when a user is not currently inhaling), and/or other factors. Thus, the pulse rate(s) for selected mix ratios may not be limited to a single pulse rate for each heating element 154a and 154b. In other embodiments, power levels supplied to the heating elements 154a and 154b may be controlled to control the mix ratio.
The vaporizer apparatus 100 may further include a respective temperature sensor (not shown) for each of the vaporizing chambers 152a and 152b. The temperature sensors may be located within or near the vaporizing chambers 152a and 152b to measure the temperatures therein. Temperature feedback may be received by the processor 156 and used to dynamically control the pulse rate(s) of the heating elements 154a to 154b to maintain the respective temperatures within a set range.
As yet another example, the vapor flow control system may comprise first and second electromagnetic switch elements. The magnetically controlled elements may each open and close an airflow path for a different vapor at variable and selective rates to achieve the desired vapour ratio. For example, the first and second airflow paths (e.g. paths 168a and 168b) for the first and second vapours may each have a respective electromagnetically controlled switch that can be rapidly opened or closed to block or allow airflow therethrough. Each of the first and second electromagnetically controlled switches may be controlled rapidly at relative rates necessary for the vapor ratio. Thus, in this example, rather than controlling a pulse rate of the heater, a pulse rate of the electromagnetically controlled gate or switch is used to control vapor flow.
The first and second electromagnetic switches may be controlled so that one of the first and second vapour paths is always open at any given time. For example, the first and second first and second electromagnetic switches may be activated in an alternating manner (between the first and second vapour paths). In order to achieve a 50/50 ratio, the open and closed cycle for each switch may be equal. For a 25/75 ratio, the first path may have a shorter “open” portion of the open/close cycle, while the second path has a longer “open” portion of the open/close cycle. For a 100% to 0% ratio, the desired vapor path may be left open, and the other closed.
For each electromagnetic switch, a spring or other biasing element may be used to close the respective path, and an electromagnet, when activated, could open the path (similar to a solenoid switch, for example). In other words, the default position of the switch may be closed. In such embodiments, rather than activating the vaporizer in response to sensing a user trying to draw vapor through the mouthpiece, a button may be used to control usage. As another option, a separate sensor configured to sense if someone is using the mouthpiece may be used. For example, the sensor may be a touch sensor on the mouthpiece. The sensor may be an air pressure sensor that senses suction and/or an airflow sensor.
In some embodiments, the currently selected mode of operation (e.g. mix ratio) may be determined on factors other than, or in addition to user input. The mix ratio may be selected based on current time and/or location information, as determined by the optional clock 176 and/or location module 178, for example. For example, at certain times of day (e.g. work hours) and/or locations (e.g. workplace) one of the first and second vapors may be restricted to 0%. For example, a vapor including one or more psychoactive components may be restricted to use during certain times of day such as non-work or after-work hours. The vapor including one or more psychoactive components may be restricted to use in certain locations, such as non-work locations, or certain geographic regions. Restricting the flow of one of the vapors may comprise deactivating or disabling (not allowing) activation of the corresponding heating element 154a or 154b.
As yet another option, the vaporizer apparatus 100 may include one or more controllable airflow restriction mechanisms. For example, the vaporizer apparatus 100 may include optional first and second airflow baffles 180a and 180b, which are positioned and configured to regulate airflow through the first and second vapor airflow paths 168a and 168b respectively. The baffles 180a and 180b are one of multiple options for controlling the vapor mix ratio. The first and second airflow baffles 180a and 180b are controlled by the processor 156 in this embodiment.
The first and second airflow baffles 180a and 180b may be controlled by the processor 156 to provide the selected mix ratio. For example, if the selected ratio is 100% the first vapor and 0% the second vapor, the first baffle 180a may be fully opened and the second baffle 180b may be fully closed. For a 50/50 mix ratio, each of the baffles 180a and 180b may be fully open, or both may be partially open to the same degree, such that the vapor flow in each of the first and second vapor airflow paths 168a and 168b is substantially similar. For a ratio that is 25% the first vapor and 75% the second vapor, the first baffle 180a may be only slightly open, while the second baffle 180b is mostly open, where the difference in baffle positions is designed to give the proper mix. While a vapor is set to 0%, the heat element may be inactive for the corresponding vaporizing chamber so that vapor is not produced.
Embodiments are not limited to baffles, and any other suitable mechanism controllable to modify airflow resistance may be used rather than baffles. Embodiments are also not limited to physical airflow resistance mechanisms for controlling vapor mix ratios.
In some embodiments, the first and second materials may both contain one or more psychoactive components, or may be substantially free of psychoactive components. The first and second materials may have different flavors, or other different characteristics, and the mix ratio may be set according to the desired vaping experience.
The first electrical connector 113 of the body 102 is a male connector including projecting from the body 102 and comprising a plurality of pins 182. Airflow is from the body 102 to the head 104 is also facilitated by the first and second electrical connectors 113 and 115 in this embodiment. Specifically, the first electrical connector 113 comprises an insulating block 187 (in the form of a projection from the body 102) with the pins 182 embedded therein, and the insulating block 187 also defines two holes 188a and 188b therethrough to permit airflow. The holes 188a and 188b are spaced apart and positioned on either side of the pins 182.
The second electrical connector 115 is a female connector and comprises an insulator block 189 with the electrical contacts 184 therein for contacting the pins 182 of the first electrical connector 113. The block 189 also defines first and second holes 190a and 190b therethrough that are axially aligned with the holes 188a and 188b, respectively, of the first electrical connector 113. The PCBA 144 also define a set of holes 192a and 192b therethrough that are axially aligned with corresponding holes 188a and 118b, and holes 190a and 190b.
The holes 188a, 190a and 192a function as a portion of the airflow intake path 174a shown in
The mouthpiece portion 106 includes a central passage 194 that extends from the suction opening 108 to an inner end where the central passage 194 terminates. The mouthpiece portion 106 further includes first and second side vapor passages 196a and 196b in communication with the chamber 186 and positioned on either side of the central passage 194. The first and second side vapor passages 196a and 196b form the first and second vapor airflow paths 168a and 168b in
The first and second side vapor passages 196a and 196b connect to the central passage 194 near the suction opening 108 and away from an inner end 193 of the central passage 194 in this embodiment. In the non-operational position, the central passage 194 receives the first electrical connector 113 of the body 102 with the pins 182 extending toward the inner end 193 of the central passage 194. By flowing vapor from the first and second side vapor passages 196a and 196b into the central passage 194 at positions away from the inner end 193 of the central passage 194, residue build up deposited over time from the first and second vapors may be kept away from the position of the pins 182 when the head is in the non-operational position. This may help prevent or reduce accumulation of residue on the pins 182 over time. Embodiments are not limited to the particular arrangement of the first and second side vapor passages 196a and 196b connect to the central passage 194 shown. Any suitable system of one or more airflow passages to carry at least one vapor to the suction opening 108 may be used.
The first electrical connector 113 may be sized to form a seal or partial seal with the suction opening 108. In other embodiments, the first electrical connector 113 may fit loosely through the suction opening 108. In some embodiments, a gap may be provided between the first electrical connector 113 and the suction opening 108. The gap may, for example, be approximately in the range of 0.1 mm to 0.5 mm. In some embodiments, the gap may be 0.3 mm.
The first oil is vaporized in the first vaporizing chamber 152a and the second oil is vaporized in the second vaporizing chamber 152b. The first and second vaporizing chambers 152a and 152b are ceramic ovens in this example. The cartridge 134 further includes first and second air intake passages 195a and 195b that receive airflow therethrough to mix with the vaporized oil to form the first and second vapors in the first and second vaporizing chambers 152a and 152b. First and second vapor paths 197a and 197b carry the first and second vapors from the first and second vaporizing chambers 152a and 152b, respectively, to first and second front passage areas 199a and 199b in the head, which in turn guide the vapors to the first and second side vapor passages 196a and 196b, respectively, of the mouthpiece portion 106.
The example electrical connection between the body 102 and the head 104 will now be described in greater detail with reference to
The first electrical connector 113 and the second electrical connector 115 may be in the form of a Universal Serial Bus (USB) connection. For example, the first electrical connector 113 and the second electrical connector 115 may be similar to a USB-C connector, which is reversible in that the male connector may mate with the female connector in a first position and in a second position that is rotated 180 degrees with respect to the first position. The first electrical connector 113 and the second electrical connector 115 may not double contacts, with each contact being assigned a different function.
In this example, the first electrical connector 113 comprises a plurality of electrical contacts in the form of a plurality of conductive pins 182. The plurality of pins 182 include first pin 182a, second pin 182b, third pin 182c, fourth pin 182d and fifth pin 182e in this example. The second electrical connector 115 comprises five conductive contacts 184a to 184e positioned to engage the pins 182a to 182e. The pins 182a to 182e may, for example, be pogo pins.
In this example, the electrical connectors 113 and 115 may be configured to allow the head 104 to be rotationally reversible about the longitudinal axis. That is, the head 104 may be docked with the body 102 in a position rotated 180 degrees about the longitudinal axis 181, relative to the position shown in
By way of example, with the dual cartridge 134 received in the head 104, the first and second conductive contacts 184a and 184b may connect with the first cartridge portion 135a (including the first reservoir 150a, the first vaporizing chamber 152a and the first heating element 154a shown in
With the head 104 received in the position shown in
Alternatively, the head may be docked with the body 102 in a position reversed about longitudinal axis 181 (i.e. rotated about the longitudinal axis 181 by approximately 180 degrees) relative to the position shown in
With reference again to
The processor 156 may change one or more operational parameters based on the one or more determined characteristics. The operational parameters may include: heating temperatures; heating pulse frequencies and/or durations; and/or other parameters of the vaporization process. One or more child safety or security parameters may also be activated or deactivated responsive to the determined identification of the one or more materials. For example, if a psychoactive material is identified, one or more child safety protocols may be activated.
In some embodiments, the one or more characteristics comprise a remaining amount of the first and/or second materials in the first and/or second reservoirs 150a and 150b. For example, the head 104 may include one or more sensors that generate an output indicative of the amount of material remaining in the first and second reservoirs 150a and 150b, and the output may be received by the processor 156.
The one or more characteristics of the cartridge 134 may comprise an orientation of the cartridge relative to the base. For example, the first electrical connector 113 may include an electrical contact (e.g. second pin 182b shown in
Embodiments are not limited to electrical contacts such as pins to determine orientation, identification information or other characteristics. For example, one or more wireless communication techniques, sensors, bar code reader and/or any other suitable means may be used to determine such orientation, identification information or other characteristics.
Information retrieved from the head 104 and/or cartridge 134 may be used to verify the source and/or content of the cartridge 134. For example, an identification or verification code may be retrieved from the cartridge 134 and verified by the processor 156. A plurality of cartridges may be provided, each having a unique identification or verification code associated therewith. Upon successful verification, operation of the vaporizer apparatus for vaping may be enabled. If verification is unsuccessful, operation of the vaporizer apparatus for vaping may be disabled. Use of counterfeit cartridges may, thereby, be prevented.
In some embodiments, the processor 156 may determine that one or both of the reservoirs 150a and 150b is empty or below a threshold, and a notification may be provided to the user to refill one or both of the reservoirs 150a and 150b accordingly. The notification may include one or more visual indications, such as one or more of the LEDs flashing. Any suitable notification method may be used. In some embodiments, the notification may be provided to a remote device, such as a remote device running an application that interfaces with the vaporizer apparatus 100.
The processor 156 may disable the corresponding heating element 154a or 154b responsive to determining that the reservoir 150a or 150b is empty or below a threshold. The processor 156 may alternatively change the mix ratio setting of the vaporizer apparatus 100 responsive to determining that the reservoir 150a or 150b is empty or below a threshold. For example, if the first material in the first reservoir 150a is below a threshold, then the ratio may be set to 100% vapor from the second material in the second reservoir 150b (or vice versa).
The determination that one or more reservoirs 150a and 150b are empty or below a threshold may be based on a timer. For example, a given material (e.g. oil strain) may be known to vaporize at an approximate rate, and a time to vaporize a substantial amount of the material may be predetermined. The processor may then determine that the total vaporization time for the cartridge 134 has approached or passed that predetermined time. For example, the predetermined vaporization time to substantially use up a given material may be approximately 30 minutes.
The determination that one or more reservoirs 150a and 150b are empty or below a threshold may be based on a measured resistance or current of the heating element 154a or 154b. The resistance or current may be dependent on the amount of the material in the reservoir, and the dependence may be known or approximated based on empirical measurements. For example, a resistance measured at the heating element may be approximately: 400 Ohm when the corresponding reservoir is approximately full; 350 Ohm when the corresponding reservoir is approximately half full; and 193 Ohm when the corresponding reservoir is approximately empty.
The determination that one or more reservoirs 150a and 150b are empty or below a threshold may be based on an airflow characteristic (e.g. airflow pressure) measured by a sensor. For example, an airflow sensor reading may be: relatively high when the corresponding reservoir is approximately full; medium or medium-high when the corresponding reservoir is approximately half full; and low when the corresponding reservoir is approximately empty.
In some embodiments, the processor 156 may determine whether the cartridge is a single pod cartridge (i.e. single reservoir and vaporizing chamber) or dual pod cartridge such as the example cartridge 134 in
The vaporizer apparatus described herein may include a wireless communication module that may communicate with a remote device. The remote device may be a mobile phone or other portable electronic device. The wireless communication module may operable for communication over a wireless network such as a Bluetooth or Wi-Fi network. The portable electronic device may run an application that retrieves and displays information about the vaporizer apparatus and/or the cartridge thereof. The information may include one or more of: one or more materials stored in the cartridge; the current levels of the one or more materials in one or more reservoirs in the cartridge; the current vapor mix ration setting of the vaporizer apparatus.
The body 102 and head 604 may have a similar shape as the vaporizer apparatus 100 of
The first and second vaporizing materials held in the first and second ovens 651a and 651b may be two different materials having different compositions and properties. For example, the first material in the first oven 651a may be a first dry herb composition and the second material in the second oven 651b may be a second, different dry herb composition. The ovens heating elements 654a and 654b are each operable to heat and vaporize material stored in the corresponding vaporizing chamber (652a or 652b). The head 604 may comprise one or more closure member (e.g. door, hatch, or cover member, etc.) that provides access to the vaporizing chambers 652a and 652b for adding or removing vaporizing material.

In this example, the vaporizer apparatus 100 comprises a processor 156 and a memory 158 operably connected to the processor 156. The memory 158 stores processor-executable instructions thereon that, when executed by the processor 156, cause the processor 156 to individually and selectively control the ovens 651a and 651b. The vaporizer apparatus 600 in this embodiment may further include a user interface 160, a power source 164, one or more visual indicator (not shown), a clock 176, and/or location module 178 similar to those of the embodiment shown in
The processor 156 may control operation of the first and second ovens 651a and 651b via PCBA 144. In other embodiments, the PCBA 144 may be omitted. The processor 156 may disable or enable one or both of the 652a and 652b at certain times of day or certain locations (as determined by the location module 178 and/or clock 176. A user may provide input, via user interface 160, to control or configure the apparatus 600.
The vaporizer apparatus 600 further includes an airflow system 155 comprising at least one airflow path to carry the first and second vapors generated in the first and second vaporizing ovens 651a and 651b to the mouthpiece portion 106. The airflow system 155 is similar to the airflow system 155 in
The vaporizer apparatus 100 in this example further includes airflow intake paths 174a and 174b. Each airflow intake path 174a and 174b is in fluid communication with the outside environment and a respective one of the ovens 651a and 651b. In this example, airflow intake paths 174a and 174b extend from the head 604 into the body 102 to inlets 175a and 175 respectively. In other embodiments, the inlets 175a and 175b may instead be in the head 604.
The head 604 comprises removable cartridge 634 held therein, which in turn holds the first and second ovens 651a and 651b. The electrical and airflow connections between the head 604 and the body 102 via electrical connectors 113 and 115 are also similar to the vaporizer apparatus 100 shown in

The mouthpiece portion 106 further includes the first and second side vapor passages 196a and 196b in fluid communication with the ovens 652a and 652b respectively and positioned on either side of the central passage 194. The first and second side vapor passages 196a and 196b receive the first and second vapors from the ovens 652a and 652b respectively. The first and second side vapor passages 196a and 196b form the first and second airflow paths 168a and 168b in
In the non-operational position shown in
The processor 156 connected to memory 158 may control operation of the single oven 751 via PCBA 144. For example, the processor 156 may disable the oven 751 oven at certain times of day or certain locations (as determined by the location module 178 and/or clock 176. A user may provide input, via user interface 160, to control or configure the apparatus 700.
In this single-oven embodiment, the head 704 includes first and second side vapor passages 196a and 196b in communication central passage 194 (which in turn extends to the suction opening 108) for delivering vapor from the oven 751 to the suction opening 108. However, in other embodiments, the side vapor passages 196a and 196b may be omitted and the central passage 194 may instead extend to the oven for flow of vapor straight from the oven 751 to the suction opening 108. Other configurations may also be used to direct vapor from the oven 751 to the suction opening 108.
At block 3702, the head (e.g. head 104, 604 or 704) is detected to be attached to the body (e.g. body 102 or 202) in the operational position. This detection may comprise detecting that a first electrical connector of the body engages the second electrical connector of the head. Alternatively, one or more sensors (not shown) in the body and/or the head may detect the head is attached to the body 102. For example, a proximity sensor in the head or body may be positioned to detect that the head is proximate the body in the operational position.
Optionally, at block 3704, while the head is in the operational position, data indicating one or more characteristics of the head is obtained. The one or more characteristics of the head may, for example, comprise at least one of: an orientation of the head; and an identify of at least one material for vaporization in the head. Any other one or more characteristics, such the examples described above, may be obtained using any of the methods discussed herein, or any other suitable method.
Optionally, at block 3706, current time and/or location information is obtained. For example, time information may be provided by a clock, and location information may be provided by a location module.

At block 3710, with the head in the operational position, operation of one or more vaporizer chambers (152a, 152b, 652a, 652b and/or 752) is enabled. Enabling operation of the one or more vaporizer chambers may comprise enabling operation of one or more heating elements (154a, 154b, 654a, 654b and/or 754) operatively coupled to the vaporizer chambers. The one or more vaporizer chambers may be individually and selectively enabled based on at least one of: the one or more characteristics of the head; the user input; the time information; and the location information. One or more of the steps shown in
At block 3802, a head is detected to be attached to a body in the operational position. This detection may comprise detecting that the first electrical connector of the body engages the second electrical connector of the head.
At block 3804, data indicating the content of at least one reservoir or oven is obtained from the head. The data may indicate one or more characteristics including: the type of heating element, the type of material used in the first cartridge portion, an amount of remaining material in the first and/or second cartridge portions, and other characteristics. The data may be stored in a memory device, chip, or other means in the head and may be retrieved by a processor in the body when the head engages the body in the operational position.
At block 3806, an orientation of the head is determined as a function of signals received via at least one pin of the first or second electrical connector. For example, the first electrical connector may comprise at least one pin offset from a central longitudinal axis, and the position of the pin when engaged to the second electrical connector may, thus, be indicative of the orientation of the head. The method may further comprise selectively and individually controlling at least one vaporizing chamber as a function of the orientation of the head.
A method according to some embodiments comprises making the vaporizer apparatus of any of the embodiments described herein. The head and the body may be provided separately.
