An accessory e-cigarette and filter assembly that is essentially a holder for both a vaporizer/e-cigarette and an exhale filter is disclosed. The device also allows for removably pairing an exhale filter to a vaporizer and provides impact protection thereto. In the preferred embodiment, a sleeve with parallel channels provides for the filter and e-cigarette to be juxtaposed however a mouthpiece for the filter and a mouthpiece for the e-cigarette are at opposite ends.

An axially rotating electric heating device for extracting tobacco includes a heating cavity outer shell, a heating cavity inner shell, and a heating assembly. The heating assembly includes a heating cavity that accommodates a smoking product and a heating element located in a cigarette heating cavity. The heating cavity is surrounded by the heating cavity inner shell; the heating element is inserted into the smoking product so as to heat the smoking product. The heating cavity inner shell is located at the front end of the heating assembly; the heating cavity outer shell and the heating cavity inner shell form an integral body; the heating cavity may rotate relative to the axis of the heating element to separate the smoking product from the heating element, thereby facilitating the extraction of the smoking product after smoking is finished.

A vaporizer cartridge and tank guard including an elongated member. The long member is a cylindrical member. The long member has a vertical hole located through a middle section. The interior of the hole is surrounded by a flexible material. This material allows a glass cartridge or tank to be removably secured within the hole. A second material is placed around the flexible material. The second material is a hard, protective material that prevents the cylinder from being crushed. The long member has an ergonomic exterior. This exterior is created by tapering the long member inward at the center.

An induction heating assembly for a vapour generating device includes an induction coil and a memory storage device. The induction coil is arranged to heat, in use, a susceptor and the induction coil is also arranged to transmit and receive, in use, an electromagnetic field to transfer data to and from an external information device.

A nicotine delivery device (200) for generating a mist containing nicotine for inhalation by a user. The device comprises a mist generator device (201) and a driver device (202). The driver device (202) is configured to drive the mist generator device (201) at an optimum frequency to maximise the efficiency of mist generation by the mist generator device (201).

A method for supplying a liquid to an inhaler cartridge includes a housing body including an accommodation space capable of accommodating a liquid, a first opening communicating with the accommodation space and opened in a first direction, and a second opening communicating with the accommodation space and opened in a second direction substantially perpendicular to the first direction, and a cap configured to be formed separately from the housing body and close the first opening. The method includes closing the first opening with the cap, and after the first opening is closed, supplying the liquid to the accommodation space through the second opening.

An aerosol delivery device is provided that includes a power source, a heating element, a switch coupled to and between the power source and the heating element, and processing circuitry coupled to the switch. The processing circuitry outputs a PWM signal during a heating time period to cause the switch to switchably connect and disconnect the output voltage to the heating element to power the heating element. The processing circuitry outputs a pulse of known current to the heating element, and measure voltage across the heating element, between adjacent pulses of the PWM signal. And the processing circuitry calculates the resistance of the heating element based on the known current and the voltage, calculates the temperature of the heating element based on the resistance, and adjusts a duty cycle of the PWM signal when the temperature deviates from a predetermined target.

A vaping atomizer for use with a vaping device is provided. The atomizer includes an enclosure portion and a heating-element housing extending through the interior of the enclosure portion. A first cavity for receiving vaping liquid is at least partially formed between the enclosure portion and the heating-element housing. The heating-element housing includes at least one aperture formed therein facilitating transfer of the vaping liquid from the first cavity to a second cavity formed on the interior thereof. The at least one aperture formed in the heating-element housing can be generally shaped as a triangle. The size and shape of the least one aperture can be optimized to prevent the vaping liquid from flooding the interior cavity, and to accommodate uses of various vaping liquids having different viscosities, as well as to prevent liquid-absorbing material provided in the second cavity from drying out to prevent dry hits during use of the vaping atomizer.

An electronic cigarette, including: an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The atomization assembly includes a mouthpiece, a glass tube, an upper seal ring and a lower seal ring with respect to the glass tube, an atomization body, a first seal ring sealing the atomization body, an air regulating ring including at least one air inlet, a second seal ring sealing the air regulating ring, a plurality of ceramic atomization cores disposed in parallel, a fixed ring fixing the plurality of ceramic atomization cores, a piece of cotton, a base, an insulation ring, and an electrode. The plurality of ceramic atomization cores is fixed on the fixed ring. The piece of cotton is disposed on the bottom of the plurality of ceramic atomization cores to adsorbs leaked condensate. The fixed ring is disposed on the base.
