Abstract: Vaporizers having a thermal wick are provided. A thermal wick may include a combination of an electrically insulating porous wicking material surrounding, enclosing, covering or embedded within a thermally conductive material. The thermally conductive material has a thermal conductance greater than that of the porous wicking material. The thermal wick reduces the viscosity of vaporizable material by transferring heat throughout the wick and warming the vaporizable material and providing a high void volume. The thermal wick allows for substantially higher total particulate masses of vaporizable material than traditional wicks.

Abstract: Vaporization devices and methods of operating them. In particular, described herein are methods for controlling the power applied to a resistive heater of a vaporization device by measuring the resistance of the resistive heater at discrete intervals. Changes in the resistance during heating may be used to control the power applied to heat the resistive heater during operation. Also described herein are vaporization devices that are configured to measure the resistance of the resistive heater during heating and to control the application of power to the resistive heater based on the resistance values.

Abstract: Vaporizer devices and methods for detecting inhalation through a vaporizer using a heating element are provided. A resistive heater of a vaporizer may function as both a heater and as an anemometer to detect inhalation. Alternatively or additionally, a separate resistive heater may be included in an air path through the vaporizer to detect a user inhaling through the vaporizer. A heating control mechanism utilizes the already existing heating element in an anemometric correlation to when the vaporizer is idle and when it is being used (where being used implies the user is taking a puff/inhalation on the vaporizer). Using this information, a controller of the vaporizer accordingly controls heating to the vaporizer as required.

Abstract: On-demand, hand-held vaporizer that operates primarily by convection. The vaporizer is configured to permit very rapid (e.g., within a few seconds) heating of air drawn through an oven chamber to a predetermined or selectable vaporizing temperature to vaporize a material (e.g., loose leaf plant material, etc.) that is held in the oven chamber. The vaporizer provides efficient transfer of air being heated as well as rapid delivery of vaporizable material to a user.

Abstract: Vaporizer device cartridges are provided. In some implementations, a cartridge comprises a storage compartment having first and second opposing ends, a sealing material sealing the second end, and a wick positioned proximate to the first end. The storage compartment is configured to hold a liquid vaporizable material. The sealing material is configured for insertion of a needle through the sealing material for dispensing the liquid vaporizable material into the storage compartment. The wick comprises opposing ends in communication with the storage compartment and is configured to allow a volume of air to exit the storage compartment through the wick when the storage compartment is being filled with the liquid vaporizable material.

Abstract: An apparatus for vaporizing a concentrate and/or a non-concentrate material is provided. The apparatus can include a housing, a reservoir, a vessel, and a heating element. The reservoir can be coupled to a lid of the apparatus and configured to hold the concentrate. The vessel can be disposed at least partially inside of the housing and can be configured to receive the reservoir when the lid of the apparatus is in a closed position with respect to the housing. The heating element can be configured to generate heat for heating the vessel, thereby vaporizing the concentrate in the reservoir to form an aerosol. Coupling the reservoir to the lid of the apparatus can enable the apparatus to be used for vaporizing the concentrate while decoupling the reservoir from the lid of the apparatus can enable the apparatus to be used for vaporizing the non-concentrate material. Related methods are also provided.

Abstract: A vaporization device includes a wick with improved aerosol production properties relative to a traditional wick, for example one formed of silica fiberglass cord. According to some aspects, the wick is formed of discontinuous fibers that are not packed together and that have varying orientations, creating a plurality of voids, or spaces, between the various fibers and along the length of the wick. This design of voids along the length of the wick allows for rapid wick saturation and air exchange. Because of this, a user can take successive long puffs without noticing much difference in vapor production, as the liquid quickly (e.g., within seconds) replenishes in the wick.

Abstract: Cartridges for use with a vaporizer device are provided.

The tank includes an end wall proximate to the second end (having a vent) and a second pair of mating members, extending from the end wall towards the first end of the cartridge, comprising third and fourth U-shaped members. The first and second pair of mating members hold the wick assembly within the tank and define a chamber comprising at least part of the wick assembly and a reservoir configured to hold vaporizable material.
