DETAILED DESCRIPTION

Referring now to the drawings wherein like reference numerals are used to identify identical components in the various views, FIG. 1A is an isometric top and side view of a device 101 for storing and vaporizing liquid media, in accordance with embodiments of the present disclosure. In an example, the device 101 can be a cartomizer for an electronic cigarette, which can be connected with a power source (e.g., battery) to provide power for an atomizer contained within the device 101. The device 101 can include a mouth piece 102 with an outlet 103, which can be configured for delivery of a vapor to a user.

The mouth piece 102 can be sized and configured to provide a user with a particular type of experience. For instance, adjusting a size and/or shape of the outlet 103 and/or a passageway within the mouthpiece, shown in FIG. 3, can result in a change in velocity of vapor exiting the outlet 103 and/or a change in particle size of the liquid media contained in the vapor. As such, a different user experience can be associated with the change in velocity and/or particle size. For example, the vapor exiting the outlet 103 may feel different to a user when it enters their mouth, as a result of the change in velocity and/or particle size. In some examples, the mouth piece 102 can comprise a pattern 104, which can be associated with a particular user experience associated with the mouth piece 102 and/or device 101. The pattern 104 can be used by a user to identify the particular user experience associated with the mouth piece 102 and/or device 101.

The device 101 can include an outer tube 105 that is connected with the mouth piece 102. In an example, the mouth piece 102 can be connected with the outer tube 105 by press-fitting the mouth piece 102 into the outer tube 105 and/or through use of an adhesive applied between the outer tube 105 and the mouth piece 102, although other connecting technologies may be used. In some embodiments, the mouth piece 102, as well as other components of the device 101, can be connected with the outer tube 105 via a snap connecter, as discussed herein. The mouth piece 102 can include a stepped portion 106 (or annular ledge) that can engage the proximal longitudinal end of the outer tube 105 to prevent the mouth piece 102 from being pushed into the outer tube further than a defined amount.

The device 101 can include a battery connector 107 (e.g., a threaded connector as shown or a frictionally-engaged connector or other connector) that is configured to connect with a complementary connector comprising part of or associated with a housing for a battery or other power source that is capable of providing power to an atomizer comprising part of the device 101. In an example, the battery connector 107 can be connected with the outer tube 105 by press-fitting the battery connector 107 into the outer tube 105 and/or, for example, through use of an adhesive applied between the outer tube 105 and the battery connector 107. The battery connector 107 can include a stepped portion 109 (or annular ledge), much like the mouth piece 102 that can engage the distal longitudinal end of the outer tube 105 to prevent the battery connector 107 from being pushed into the outer tube 105 further than a defined amount.

The battery connector 107 can establish both a physical connection between the device 101 and a housing for a power source and an electrical connection between the power source (e.g., the battery in the housing) and the device 101. In an example, the physical connection can be established by a first threaded portion 108, which can be configured to threadingly connect with a complimentary threaded portion associated with the battery. The first threaded portion 108 of the connector 107 can be constructed from an electrically conductive material (e.g., metal). The connector 107 may further comprise, for example, a center connector 111, which may also be constructed from an electrically conductive material. As discussed further below, the first threaded portion 109 and the center connector 111 may be electrically insulated from each other by an annular insulator grommet 110. Thus, the connector 107, via the first threaded portion 108 and the center connector 111, can facilitate an electrical connection between a first terminal (e.g., positive terminal) and a second terminal (e.g., negative terminal) of the battery.

FIG. 1B is an isometric bottom and side view of the device 101 in FIG. 1A, in accordance with embodiments of the present disclosure. The device 101 includes the mouth piece 102, the stepped portion 106 of the mouth piece 102, the outer tube 105, the battery connector 107, the threaded portion 108 of the battery connector 107, and the stepped portion 109 of the battery connector 107. FIG. 1B further illustrates details associated with the battery connector 107, which can include an annular insulator grommet 110 that is inserted into an axial cylindrical opening of the battery connector 107. The annular insulator grommet 110 can include an axial cylindrical opening, in which a center battery connect 111 can be inserted. The annular insulator grommet 110 can be formed from an insulative material that separates the center battery connect 111 from the threaded portion 108 and/or stepped portion 109. For example, the annular insulator grommet 110 can be formed of a plastic, rubber, ceramic, etc., which can prevent a short from occurring between the center battery connect 111 and the threaded portion 108 and/or stepped portion 109.

In some embodiments, the center battery connect 111 can include an axial cylindrical opening 112 in the center battery connect 111 that is in communication with the inner surface of the inner tube 118. In an example, a first terminal of the battery can be connected with the threaded portion 108 and/or stepped portion 109 and a second terminal of the battery can be connected with the center battery connect 111. For instance, a positive terminal of the battery can connect to the threaded portion 108 and/or stepped portion 109 and a negative terminal of the battery can connect to the center battery connect 111.

FIG. 1C is a side-view of the device 101 in FIG. 1A, in accordance with embodiments of the present disclosure. The device 101 includes the mouth piece 102 with stepped portion 106. The mouth piece 102 can be connected with the outer tube 105 and can include stepped portion 106. In addition, the device 101 can include battery connector 107 that has a threaded portion 108 and stepped portion 109. The battery connector 107 can include an axial cylindrical opening in which an insulator grommet 110 (as shown in FIG. 1B) can be inserted to provide an insulative layer between a center battery connect 111 inserted in an axial cylindrical opening of the insulator grommet 110 and the threaded portion 108 of the battery connector 107. In addition, the device 101 can include an air inlet 113 through which air can be drawn into the device 101. In some embodiments, the device 101 can include more than one air inlet 113. For example, air can be drawn through an axial cylindrical opening of the center battery connect 111.

FIG. 1D is an isometric top and side view of an electronic cigarette, in accordance with embodiments of the present disclosure. The electronic cigarette includes a device 101 that is connected with a battery assembly 114. The battery assembly 114 can include a power source (e.g., battery) that is used to power a heater coil housed in the device 101, as discussed herein. The connection between the device 101 and the battery assembly 114 can be a threaded connection and/or a frictionally-engaged connection or other type of connection that is configured to connect the device 101 and the battery assembly 114. In an example, the threaded connection can include a first threaded portion on the device 101 and a complimentary threaded portion on the battery assembly 114. The frictionally-engaged connection can include two complementary connectors that are configured to frictionally engage one another, as discussed herein. Upon connection of the device 101 and the battery assembly 114, a joint 115 can be formed between the device 101 and the battery assembly 114.

FIG. 1D further depicts the mouth piece 102 of the device 101. The mouth piece 102 includes the outlet 103 where vapor exits the electronic cigarette, as a user draws from the mouth piece 102. As discussed herein, the stepped portion 106 of the mouth piece 102 can engage the proximal end of the outer tube 105, thus preventing the mouth piece 102 from being pushed into the outer tube 105 further than a defined amount. In addition, the mouth piece 102 can comprise the pattern 104, such that a user can identify the particular user experience associated with the mouth piece 102 and/or device 101.

In some embodiments, the battery assembly 114 can include a light assembly 116 on a tip of the battery assembly 114 distal to the device 101. The light assembly 116 can include a light filter and a light emitting diode (LED). As a user draws on the mouth piece 102, the LED can generate light which passes through the light filter. In an example, the light filter can disperse the light generated by the LED and/or can impart a particular color to the light generated by the LED.

FIG. 2 is a cross-sectioned view of the device 101 of FIG. 1C taken along line 2-2, in accordance with embodiments of the present disclosure. The device 101 can include a liquid media storage tank 117 that can be configured to hold a liquid media. In an example, the liquid media can include a smoking liquid that can be vaporized by an atomizer and inhaled by a user. The liquid media can include a flavoring and/or nicotine to enhance a user's experience. The liquid media storage tank 117 can be annular in shape and can be defined by an outer surface of an inner tube 118 and an inner surface of an outer tube 105.

In some embodiments, the inner tube 118 and/or the outer tube 105 can be annular in shape. The inner tube 118 and the outer tube 105 can be connected with a mouth piece 102, in some embodiments. As such, vapor can travel through an air path 123 defined by an inner surface of the inner tube 118 through a passageway 120 formed in the mouth piece 102. In addition, by connecting the outer tube 105 to the mouth piece 102, a proximal end of the liquid media storage tank 117 can be sealed by a connection between the outer tube 105 and the mouth piece 102 and a connection between the inner tube 118 and the mouth piece 102. Alternatively, in some embodiments, a proximal seal 121 can be placed between the inner tube 118 and the mouth piece 102, as illustrated in FIG. 2. In an example, the proximal seal 121 can have an outer surface that connects with an inner surface of the outer tube 105 and can have an inner surface that connects with an outer surface of the inner tube 118, thus sealing the proximal end of the liquid storage media tank 117.

In some embodiments, the proximal seal 121 and the outer tube 105, and/or other portions of the device 101 (e.g., mouth piece 102 and outer tube 105, inner tube 118 and proximal seal 121, heater coil housing 127 and heater coil support 128, outer tube 105 and battery connector 107, etc.) can be connected via snap connectors 151, 153. The snap connectors 151, 153 can include a lip portion and a corresponding recessed portion that engage one another. In an illustrative example, when the proximal seal 121 has been inserted into the outer tube 105 an appropriate amount, the lip portion and the corresponding recessed portion can engage one another, as discussed further in relation to FIG. 4.

Alternatively, and/or in addition, elements 151, 153 can represent seals. In an example, the upper seal 121 and/or battery connector can have an annular groove extending around an outer perimeter between an inside of the outer tube and the upper seal 121 and/or between the inside of the outer tube and the upper seal 121. Each groove can have a proximal wall and a distal wall and material between the proximal wall and the distal wall can be removed to form the groove. In some examples, a seal can be placed in the grooves between the proximal wall and distal wall. For instance, an annular seal can be placed in the grooves and when the upper seal 121 and/or the battery connector 107 is inserted into the outer tube, the seal can be deformed and compressed between the battery connector 107 and the outer tube 105 and the upper seal 121 and the outer tube 105. Thus, a seal can be created between the battery connector 107 and the outer tube 105 and/or between the upper seal 121 and the outer tube 105.

In some embodiments, a distal end of the inner tube 118 can be connected with a chamber air outlet 125 of a heater coil chamber 122. The heater coil chamber 122 can include a chamber that houses a heater coil 124, a chamber air inlet 126, and the chamber air outlet 125. In an example, the heater coil 124 can vaporize liquid media drawn from liquid media storage tank 117, which can be mixed in the heater coil chamber 122 with air received from the chamber air inlet 126. The mixture of vapor and air can then be drawn through the chamber air outlet 125, through the inner tube 118 and passageway 120 of the mouth piece 102.

The heater coil chamber 122 can be formed by a heater coil housing 127 that includes the chamber air outlet 125 and a heater coil support 128 that includes the chamber air inlet 126. Together, the heater coil housing 127 and the chamber coil support 128 can form the heater coil chamber 122. The heater coil housing 127 can be annular in shape and can include a neck portion 129 and a base portion 130. The neck portion 129 can have an inner diameter that is less than an inner diameter of the base portion 130 and can be configured to receive the distal end of the inner tube 118. Forming the inner tube 118 and the heater coil housing 127 as separate components can be advantageous when different lengths of the device 101 are produced. For example, in contrast to prior methods that form the inner tube and heater coil housing/heater coil chamber from one piece, if various sizes of electronic cigarettes are produced, a longer/shorter inner tube 118 may be used, rather than producing a new one piece assembly that includes a heater coil housing and an inner tube of a different length.

The heater coil support 128 can be annular in shape and can include a neck portion 131 and a base portion 132. In some embodiments, an outer diameter of the base portion 132 of the heater coil support 128 can be less than an inner diameter of the base portion 130 of the heater coil housing 127. The base portion 132 of the heater coil support 128 can be inserted into the base portion 130 of the heater coil housing 127 and connected with the base portion 130 of the heater coil housing 127. The heater coil housing 127 and the heater coil support 128 define the heater coil chamber 122 between the chamber air inlet 126 and the chamber air outlet 125.

Some embodiments of the present disclosure can include a removable flavoring pack. In an example, juice can be included in the liquid media storage tank 117, which contains nicotine. Flavoring can be contained in a separate pack that can be attached to the device 101. As such, when a user draws from the device 101, flavoring can be introduced into the air path that travels through the device. In some examples, the mouth piece 102 can be detachable and a flavor pack can be inserted upstream (distal) from the mouth piece 102. In an example, a flavor pack can be inserted between the battery connector 107 and the battery assembly.

In some embodiments, the flavoring pack can include electrical contacts on either end of the flavoring pack that connect the coil 124 to the battery assembly. The flavoring pack can include an electrical lead that connects the center battery connect 111 to a corresponding terminal of the battery assembly. In addition, the flavoring pack can include an additional electrical lead that connects the neck portion 145 of the battery connector 107 to a corresponding terminal of the battery assembly.

In some embodiments, the flavoring pack can include a hole that passes longitudinally through the flavoring pack and connects the axial cylindrical opening 112 to a corresponding axial cylindrical opening of the battery assembly. An annular flavoring tank can surround the hole that passes longitudinally through the flavoring pack, and can be formed by an inner and outer cylindrical wall. In some embodiments, the flavoring pack can contain one or more orifices passing through the inner cylindrical wall, such that flavoring juice can pass from the annular tank and into the hole that passes longitudinally through the flavoring pack. In an example, as a user draws on the device 101, a pressure differential can be created between an interior portion of the annular tank and the hole that passes longitudinally through the flavoring pack. Thus, flavoring juice can be drawn from the flavoring pack into the hole and travel proximally through the device and be inhaled by the user.

In some embodiments, media can be placed in the hole of the flavor pack that absorbs the flavoring, as the flavoring is drawn from the tank through the orifices. In an example, the media can be a cotton like media and/or a porous media. As air passes over the media that contains the absorbed flavoring, the flavoring can be evaporated. In some embodiments, the media can increase a rate at which the flavoring juice evaporates and is introduced into the air path of the device 101. For example, as the flavoring juice is absorbed by the media, a surface area of the flavoring juice exposed to air passing through the media can be increased, thus increasing a rate at which the flavoring juice evaporates.

In some embodiments, the flavoring pack can include a separate wick and heater coil. For instance, the electrical leads in the flavoring pack that connect the coil 124 in the device 101 to the battery assembly can also be connected to a coil located in the longitudinal hole that passes through the flavoring pack. In an example, the coil located in the flavoring pack can be wired in series and/or in parallel with the coil 124 in the device 101. In some embodiments, a wick can extend through an orifice located in the inner cylindrical wall and extend through the wick. The flavoring juice can be pulled from the annular tank along the wick to the coil, where vaporization can occur.

FIG. 3 is an isometric, cross-sectioned view of the top and side of the device 101 depicted in FIG. 2 rotated 90 degrees about a longitudinal axis of the device 101 from the orientation depicted in FIG. 2. The device 101 includes a mouth piece 102 inserted into a proximal end of an outer tube 105. A liquid media storage tank 117 can be included in the device 101 and can be formed by the outer tube 105 and the inner tube 118. In some embodiments, a proximal seal 121 can be placed between the inner tube 118 and the mouth piece 102, as discussed herein, and an outer surface of the proximal seal 121 can connect with an inner surface of the outer tube 105 to create a seal between the liquid media storage tank 117 and the mouth piece 102.

In some embodiments, the proximal seal 121 can include an expansion chamber 136 and the mouth piece 102 can include a passageway 120, through which vapor can flow. In an example, the expansion chamber 136 can have a larger diameter than the inner diameter of the inner tube 118, thus slowing a flow of the vapor to cause turbulence and an increased mixing and/or breaking apart of liquid droplets in the air stream. The vapor can then flow through the passageway 120, which has a smaller inner diameter than the expansion chamber 136, where the flow of the vapor can be sped up, causing additional mixing and/or breaking apart of liquid droplets in the air stream.

In some embodiments, an inner diameter at the distal end of the inner tube 118 can be a same size as an inner diameter at the proximal end of the inner tube 118, resulting in a cylindrical inner surface. Alternatively, in some embodiments, an inner diameter at the distal end of the inner tube 118 can be larger than an inner diameter at the proximal end of the inner tube 118, thus forming a frustoconical shape. In an example, the frustoconical shape of the inner tube 118 can speed up a flow of the vapor through the inner tube 118 before the vapor exits into the expansion chamber 136, in some embodiments. The consecutive speeding up of the flow of the vapor in the inner tube and slowing down of the flow of vapor in the expansion chamber 136 can cause turbulence and thus increased mixing and/or breaking apart of liquid droplets in the air stream.

In an example, such an arrangement can allow for an increased mixing and/or breaking apart of the liquid droplets in the air stream without use of in-stream mixers, while providing a desirable user experience, as opposed to prior methods. For example, some prior methods can have structures that are located in the air stream to change a direction of the flow and/or create turbulence in order to break apart liquid droplets. However, this can cause a restriction in the air path, affecting a user's experience when they draw air through the electronic cigarette. For instance, a user may encounter an increased resistance when drawing air through the electronic cigarette. This can result in a user receiving a less than desired amount of vapor, as opposed to embodiments of the present disclosure, which provide an unrestricted air path 123.

The device 101 can include the heater coil chamber 122 that is formed by the heater coil housing 127 and the heater coil support 128, which houses the heater coil 124. In some embodiments, the heater coil 124 can be disposed horizontally across the heater coil chamber 122, as illustrated in FIG. 3. Alternatively, the heater coil 124 can be disposed vertically within the heater coil chamber 122.

In some embodiments, a wick 137 can extend through a center of the heater coil 124 and through a port in a sidewall of the heater coil chamber 122 into a recessed pocket 140¹, 140², 140³, 140⁴, hereinafter generally referred to as recessed pocket 140, of the liquid media storage tank 117. The wick 137 can extend through a port that extends through the heater coil support 128, and in some cases can extend through the heater coil housing 127. In some examples, one side of the wick 137 can extend through the port in the sidewall of the heater coil chamber 122. Alternatively, a first side of the wick 137 can extend through a first port 139¹ in the heater coil chamber 122 into a portion of the recessed pocket 140⁴ and a second side of the wick 137 can extend through a second port 139² in the heater coil chamber 122 located on an opposite side of the heater coil chamber from the first port 139¹ into a portion of the recessed pocket 140³.

In some embodiments, the recessed pocket 140¹, 140², 140³, 140⁴ can be formed by an outer surface of the heater coil housing 127 and the inner surface of the outer tube 105. For example, the recessed pocket 140 can be formed by an outer surface of the base portion 130 of the heater coil housing 127 and the inner surface of the outer tube 105, forming an annular recessed pocket 140 around the base portion 130 of the heater coil housing 127.

In an example, the recessed pocket 140 can be configured to retain liquid from the liquid medium storage tank 117, as a result of surface tension. For instance, liquid that enters the recessed pocket 140 can tend to want to remain in the recessed pocket 140, independent of a subsequent orientation of the device 101. Accordingly, a greater amount of liquid in the liquid medium storage tank 117 can be used by the device 101, because remaining liquid, even a small amount, can be retained in the recessed pocket 140 and wicked to the heater coil 124 by the wick 137. In addition, a consistent flow of liquid can be provided to the heater coil 124 by the wick 137 from the liquid medium storage tank 117 up until a point where all, or nearly all of the liquid is used, in contrast to use of a porous material that holds the liquid, as used in prior methods. Because the liquid is free to move about in the liquid media storage tank 117 and does not have to travel through a porous media, which can slow the transfer of the liquid to the wick 137, a consistent amount of liquid can be provided to the wick 137.

In some prior methods that employ a tank to hold the liquid, the liquid may not make consistent contact with the wick, because the liquid is free to move about the tank (e.g., per different orientations of the device 101) and thus may not be drawn consistently to the heater coil via the wick. However, in embodiments of the present disclosure, as discussed herein, the liquid is free to move about the liquid media storage tank 117, but can be retained in the recessed pocket 140, thus ensuring a constant supply of liquid to the heater coil via the wick. The recessed pocket can be sized such that enough liquid is trapped in the recessed pocket 140 to provide liquid for one or more uses (e.g., puffs) by a user. In some examples, after the user removes the device 101 from their mouth after a puff, the orientation of the device 101 can be changed and the recessed pocket 140 can be refilled with liquid from the liquid media storage tank 117, which can subsequently be wicked to the heater coil 124.

In some embodiments, the outer surface of the heater coil housing 127 proximate to the ports 139¹, 139², can be recessed and/or cut out to form individual recessed pockets 138¹, 138² for each port 139¹, 139². In some embodiments, a portion of the heater coil housing 127 bordering the ports 139¹, 139² can be recessed and/or cut out to form individual recessed pockets 138¹, 138². For example, as illustrated in FIG. 3, individual recessed pockets 138¹, 138² can be formed proximate to each port 139¹, 139², which are further recessed areas in the recessed pocket 140. In an example, where only one port exists, a single recessed pocket can be formed proximate to the port. In some embodiments, the wick 137 can extend through a center of the heater coil 124 through the first port 139¹ in the heater coil support 128 into a first individual recessed pocket 138¹ in the liquid media storage tank 117 and through a second port 139² in the heater coil support 128 into a second individual recessed pocket 138² in the liquid media storage tank 117.

In some embodiments, the device 101 can be assembled in a particular way so as to maximize a volume of liquid and reduce an amount of pressure that is developed in the liquid media storage tank 117. In an example, when a pressure in the liquid media storage tank 117 is increased, the increased pressure can force liquid out of the ports 139¹ and 139², causing liquid to be wasted and also causing possible interference with electronic components as a result of the liquid migrating from the ports 139¹ and 139² and/or wick 137. As such, it can be desirable to maintain a reduced pressure within the liquid media storage tank 117.

In some embodiments, when assembling the device, the proximal seal and the mouth piece can be inserted first, along with the inner tube 118 and heater coil housing 127. The device 101 can be oriented so the mouth piece 120 points downward and a distal end of the outer tube 105 points upward. In an example, the device can then be filled with liquid to a level that is below a proximal side of the ports 139¹ and 139². The heater coil support 128, coil 124, wick 137, and battery connector 107 can then be inserted into the distal end of the outer tube 105. Inserting the heater coil support 128, coil 124, wick 137, and battery connector 107 into the distal end of the outer tube 105 can result in a build-up of pressure in the liquid media storage tank 117. However, because the device 101 is placed in an orientation where the ports 139¹ and 139² remain above a level of the liquid in the liquid media storage tank 117, air can pass through the ports 139¹ and 139² and out of the device 101 via the axial cylindrical opening 112 and/or the passageway 120 in the mouthpiece 102.

Alternatively, if the device 101 is placed in an orientation where the battery connector 107 points downward and is subsequently filled, liquid can leak from the ports 139¹ and 139², as the upper seal 121 is set in place. For example, placement of the upper seal can cause an increased pressure in the liquid media storage tank 117, thus causing liquid to be expelled from the ports 139¹, 139².

With reference to FIG. 2, the device 101 can include a battery connector 107 that comprises an annular outer surface that connects with the inner surface of the outer tube 105 and an annular inner surface configured to connect with an insulator grommet 110 and center battery connect 111. In some embodiments, the battery connector 107 can include a cylindrical base portion 144 and a cylindrical neck portion 145 connected to one another. In some examples, the base portion 144 of the battery connector 107 can be inserted into a distal end of the outer tube 105 a defined amount. For example, the base portion 144 of the battery connector 107 can be inserted into the distal end of the outer tube 105 up until stepped portion 109 makes contact with the outer tube 105. In some embodiments, the battery connector 107 can also be connected with the neck portion 131 of the heater coil support 128. The base portion 144 of the battery connector 107 can include an axial cylindrical with a diameter that is larger than the neck portion 131 of the heater coil support 128. In an example, the diameter of the neck portion 131 of the heater coil support 128 and the diameter of the axial cylindrical opening of the base portion 144 of the battery connector 107 can be such that the neck portion 131 of the heater coil support 128 can be press fit into the base portion 144 of the battery connector 107.

In some embodiments, the battery connector 107 can include a neck portion 145 and an outer surface of the neck portion 145 can include a threaded portion 108 for threading into a battery assembly. The neck portion 145 of the battery connector 107 can include an axial cylindrical opening and a retainer ring 146 disposed around a perimeter of the axial cylindrical opening. An insulator grommet 110 can be inserted into the axial cylindrical opening of the neck portion 145 of the battery connector 107.

In some embodiments, the insulator grommet 110 can be made of an insulative material that is flexible such as a plastic and/or rubber and can be connected with the battery connector 107 via a lip portion 150. In an example, the insulator grommet 110 can be inserted into the axial cylindrical opening in the neck portion 145 of the battery connector 107 and the lip portion 150 can engage the retainer ring 146. The insulator grommet 110 can include an axial cylindrical opening in which a center battery connect 111 can be inserted. The center battery connect 111 can include a lip portion 147 that can engage the insulator grommet 110 to connect the center battery connect 111 to the insulator grommet 110 and to the battery connector 107. The center battery connect 111 can include an axial cylindrical opening 112 through which air can be drawn into the chamber air inlet 126. In an example, the axial cylindrical opening 112 can be in communication with an air path located in the battery assembly connected with the battery connector 107. Air can be drawn through the battery assembly and into the axial cylindrical opening 112.

The insulator grommet 110 can provide an insulative spacer between the center battery connect 111 and the neck portion 145 of the battery connector 107 and the base portion 144 of the battery connector 107. In an example, a first terminal of the battery can electrically connect with the center battery connect 111 and a second terminal of the battery can electrically connect with the neck portion 145 and/or base portion 144 of the battery connector 107 via the threaded portion 108. Power can be provided to the heater coil 124 via a wire 152 connected with a first side of the heater coil 124 and the base portion 144 and/or neck portion 145 of the battery connector 107 and a wire 148 connected with a second side of the heater coil 124 and the center battery connect 111. In an example, as previously discussed, wires 148, 152 can also extend through passageways (not shown) in the neck portion 131 of the heater coil support 128 from the heater coil 124 to the center battery connect 111 and/or to the base portion 144 and/or neck portion 145 of the battery connector 107, thus connecting terminals of the battery to the heater coil 124.

Alternatively, the wires 148, 152 can extend through the chamber air inlet 126. In some embodiments, a wire holder 119 can be provided that can guide the wires 148, 152 from the center battery connect 111 to the heater coil 124. In an example, the wire holder 119 can hold the wires 148, 152 in a center of the passage way and/or in the chamber air inlet 126 such that the wires 148, 152 do not rub on the heater coil support 128, causing a short, for example. In some examples, the heater coil support 128 and/or the heater coil housing 127 can be electrically connected with the base portion 144 and/or the neck portion 145 of the battery connector 107. As such, a wire can extend from the heater coil 124 to the heater coil housing 127 and/or the heater coil support 128 to electrically connect the heater coil 124 to the battery, in some embodiments.

In some embodiments, the battery connector 107 can include an air inlet 113 that can be in communication with an air inlet chamber 149. As a result of a user drawing air through the mouth piece 102, air can be drawn in through the air inlet 113 and into the air inlet chamber 149. The air can be drawn through the chamber air inlet 149 and into the heater coil chamber 122. Liquid that has been wicked into the heater coil 124 via the wick 137 can be heated and vaporized and can be drawn through the air path 123 and passageway 120 into the user's mouth. In some embodiments, the air and vaporized liquid can be drawn into the expansion chamber 136, as discussed herein.

With reference to FIG. 3, the battery connector 107 is shown inserted into the distal end of the outer tube 105 and includes the threaded portion 108, the center battery connect 111, and the insulator grommet 110. In some examples, air can be drawn into the air inlet chamber 149 from an air inlet and an axial cylindrical opening 112 in the center battery connect 111, as shown in FIG. 2, and into the heater coil chamber 122, where liquid can be vaporized by the heater coil 124 and can be drawn through the inner tube 118 into the expansion chamber 136 and through the passageway 120 of the mouth piece 102.

FIG. 4 depicts a connector, in accordance with embodiments of the present disclosure. The inner tube 184 is shown as inserted into proximal seal 180, and proximal seal 180 is shown as inserted into outer tube 183 and connected with outer tube 183 via a frictionally engaged connection. In an example, the outer tube 183 has a lip portion 182 and the proximal seal has a corresponding recessed portion 181. As discussed herein, the proximal seal 180 and the outer tube 183, and/or other portions of the device 101 and/or electronic cigarette (e.g., mouth piece 102 and outer tube 105, inner tube 118 and proximal seal 121, heater coil housing 127 and heater coil support, outer tube 105 and battery connector 107, etc., as shown in FIGS. 2 and 3) can be connected via a frictionally engaged connection. The frictionally engaged connection can include a lip portion 182 and a corresponding recessed portion 181 that engage one another when the proximal seal 121 has been inserted into the outer tube 105 an appropriate amount to cause the lip portion 182 and the corresponding recessed portion 181 to engage one another.

In an example, prior methods can use rubber o-rings to create a seal between various portions of an electronic cigarette. For instance, portions that form a tank of an electronic cigarette can be connected and can be sealed via a gasket, such as a rubber o-ring. However, over time, these types of seals can expand and contract, become brittle, and/or can be damaged in an assembly process. Accordingly, embodiments of the present disclosure can provide a frictionally engaged connection that can connect various portions of the device 101, create a seal to prevent liquid from leaking from the tank portion, and aid in assembly of the device 101.

In some embodiments, the various components of the device 101 can be made from a polymer (e.g., plastic), which can provide cost benefits associated with material and manufacturing costs. In an example, use of a semi-elastic polymer can be desirable for use in construction of the frictionally engaged connection, as the polymer components of the device 101 can flex from their original state when one component is being inserted into another and then snap back into their original state when the lip portion 182 is lined up with the corresponding recessed portion 181. For illustration purposes, FIG. 4 illustrates a space between the lip portion 182 and the corresponding recessed portion 181, however, it can be desirable to have little and/or no space between the lip portion 182 and the corresponding recessed portion 181 to maintain a good seal between the various components to prevent liquid from escaping. In addition, having little and/or no space between the lip portion 182 and the corresponding recessed portion 181 can create a stronger connection between various components that the frictionally engaged connection is connecting.

In some embodiments, the frictionally engaged connection can be beneficial when assembling the device 101. For instance, when inserting the proximal seal 180 into the outer tube 183 (or inserting other components into one another), the proximal seal 180 can be inserted into the outer tube 183, until the corresponding recessed portion 181 lines up with the lip portion 182. As such, one component can be inserted into another component a uniform amount between devices, since the separate components are not connected until the corresponding recessed portion 181 lines up with the lip portion 182. In some embodiments, an adhesive can be used in addition to the frictionally engaged connection. In an example, adhesive can be applied to one or both of the components and they can be inserted into one another until the corresponding recessed portion 181 engages the lip portion 182. The frictionally engaged connection can hold the components together while the adhesive cures, in some embodiments.

The vapor tube 222 can be sized to interact with the movable lid 207 to depress the movable lid 207 into the refill cavity 214. As seen in FIG. 6B, when the vapor tube 222 interacts with the movable lid 207, a fluid path is opened from the bottle cavity 204 to the tank cavity 224. In the illustrated embodiment a liquid can move from the bottle cavity 204 through the at least one liquid port 206 and the refill cavity 214, past the movable lid 207 and in to the tank cavity 224. When the refill bottle 201 is removed from the eCig tank 220 the movable lid 207 is moved back against the shoulder 211 of the refill assembly 202 by the force of the spring 210. Once the movable lid 207 is placed against the shoulder 211 the refill bottle 201 is sealed and liquid within the bottle cavity 204 is impeded from exiting the refill bottle 201.

In one embodiment the eCig tank can comprise a mouth piece as discussed earlier. The mouth piece can be removably coupled to the tank housing.
