Vaporizer cartridges and vaporizer apparatuses, and methods for making, using and delivering vapor to a user, that are leak-resistant for use with cannabinoids. In particular, described herein are leak-resistant vaporizer cartridges and apparatuses adapted for use with oil-based vaporizable materials including cannabis oils.

Features relating to a cartridge for use with a vaporizer body are provided. The cartridge mates with the vaporizer body in a cartridge receptacle. The cartridge may include a cartridge body defining a reservoir configured to contain vaporizable material; a mouthpiece coupled to a proximal end region of the cartridge body; at least one proximal absorbent pad wedged within an internal volume of the mouthpiece; a mouthpiece seal with sealing ribs; a cannula defining a vaporization chamber extending through the cartridge body; a resistive heating element; a porous wick configured to draw the vaporizable material in the reservoir towards the vaporization chamber; an internal sealing gasket positioned in a distal end region of the cartridge body; a lower support structure positioned in the distal end region of the cartridge body; and at least one distal absorbent pad configured to wedge within a recess located in the lower support structure.

Apparatuses, including systems and devices (“vaporizers”), for vaporizing material to form an inhalable aerosol that include capacitive lips sensing to regulate the temperature of the vaporizer, including transiently boosting the temperature. Methods of operating a vaporizer having a capacitive lip sensor are also described.

Aspects of the current subject matter are directed to transitioning a vaporizer device between different modes of operation including an active mode, a standby mode, and a deep standby mode. The vaporizer device may include a pressure sensor to measure a first pressure in an air flow path, and an ambient pressure sensor to measure a second pressure corresponding to an atmospheric pressure. The transition between different modes of operation may change the sampling frequency and/or resolution of the pressure sensor and/or the ambient pressure sensor such that sampling occurs at a higher frequency and/or resolution when the vaporizer device is in an active mode. Additionally, a comparison of the pressure in the air flow path with the ambient pressure after a heating element is activated may serve as a verification by the vaporizer device that a user is drawing on the vaporizer device.

A cartridge includes an atomizer assembly, a reservoir, and a mouthpiece. The atomizer assembly may heat a vaporizable material to generate an inhalable vapor. The reservoir may store the vaporizable material and include a wick housing and a reservoir body. The wick housing may surround at least a portion of the atomizer assembly and form a proximal wall of the reservoir. The reservoir body may be coupled to the wick housing and form a distal wall of the reservoir. The mouthpiece may deliver the inhalable vapor.
