Vaporizer devices are disclosed that are configured to detect when a puff is occurring and exclude a pressure change unrelated to the puff based on at least first and second signals. Methods for detecting a puff and excluding a pressure change unrelated to the puff based on at least first and second signals are also disclosed.

A device for heating a vapour forming substance includes a compartment for receiving a vapour forming substance. The compartment is divided into plural regions. A heater is provided for heating a vapour forming substance in the compartment in use to generate vapour therefrom. The device further includes means for controlling the heater such that a region adjacent to the heater can be selectively heated and so that vapour from that selectively heated region passes out from the device during operation of the heater. The heater extends in the longitudinal direction of the compartment.

An electronic aerosol-generating device includes a housing extending between first and second ends along a longitudinal axis. The second end of the housing defines a cavity for receiving a consumable containing an aerosol generating substrate. The device further includes a heating component comprising a heating element extending along the longitudinal axis within the cavity and configured to penetrate into the aerosol generating substrate when the consumable is inserted into the cavity. The heating element comprises a material having a Curie temperature of less than 500° C. The device also includes an inductor comprising an inductor coil positioned to transfer magnetic energy to the heating element. The inductor is configured to induce eddy currents and/or hysteresis losses in the heating element. The device further includes a power supply operably connected to the inductor and control electronics operably connected to the power supply and configured to control heating of the heating element.

An electronic cigarette and a method for manufacturing an atomizing assembly thereof. The electronic cigarette comprises a liquid reservoir used for storing an e-liquid, and an atomizing assembly received in a shell. The atomizing assembly comprises: a liquid-absorbing element connected to the liquid reservoir, wherein the liquid-absorbing element is made of porous ceramic, and has a liquid-absorbing surface for absorbing the e-liquid and an atomizing surface; and a heating element embedded in the liquid-absorbing element, wherein the edge of the heating element is internally tangent to the atomizing surface, and the heating element is used for converting the e-liquid absorbed by the liquid-absorbing element into smoke. The electronic cigarette further comprises a power supply assembly received in the shell, connected to the atomizing assembly, and used for supplying power for the heating element.

An aerosol provision device includes a first section for containing an aerosolizable substance from which a flow of aerosol can be generated; and a second section for containing a material. In use, a flow of aerosol generated from aerosolizable substance in the first section flows through material in the second section before being inhaled by a user. The first section and the second section are located in a side-by-side arrangement in the device.

The disclosure provides an automatically controlled heat-not-burn electronic cigarette device and a control method thereof. The electronic cigarette device comprises a housing, a housing lid and a heating tube arranged in the housing, a heat-insulating tube, an automatic lid opening and/or closing mechanism, a cigarette detecting mechanism, an intelligent control circuit board, a button, and a battery. The intelligent control circuit board is arranged with a main control chip, a heating control module, an automatic lid opening and/or closing control module, a button control module, a detector control module, and a charging management module. The main control chip is configured to control the electronic cigarette device to enter a smoking operation mode, or a sleep state, or an off state, on the basis of the determination of whether a cigarette is received in the heating tube within a certain time.

To provide an inhaler cartridge and an inhaler including a novel structure. Provided is a cartridge for an inhaler. The cartridge includes: a housing including an accommodation space capable of accommodating a liquid, an air flow passage, and a partition member partitioning the accommodation space and the air flow passage in a longitudinal direction; and a heater configured to be capable of heating the liquid and arranged in the air flow passage. The partition member includes an opening opened in a transverse direction to bring the accommodation space into communication with the air flow passage. The opening includes an upstream-side opening edge and a downstream-side opening edge. The partition member includes an upstream-side end and a downstream-side end. A distance between the upstream-side opening edge and the upstream-side end is smaller than a distance between the downstream-side opening edge and the downstream-side end.

The present invention relates to an electronic atomizing device and a liquid injecting structure thereof. The liquid injecting structure includes an outer tube and a liquid injection assembly in the outer tube. The outer tube defines an inlet port, the liquid injection assembly includes a switch assembly rotatable between an injecting position and a working position relative to the outer tube; the switch assembly includes a liquid injection tube defining an injecting port. When the switch assembly is in the injecting position, the injecting port is fluidly communicated with the inlet port, such that liquid can be injected into a liquid storage cavity; when the switch assembly is in the working position, the injecting port is isolated from the inlet port. The rotation operation is child-resistant; when the switch assembly is in the working position, the liquid injecting structure is shielded by a battery and cannot be opened accidentally.

Exemplars include controls, limits or the selective stopping of vapor flow through a vaporizer cartridge and tip. A blocking member such as a deformable squeeze valve formed as at least a portion of the tip or a plunger formed within a cap having ports which fluidly communicate from the outside of the cap to the inside which is selectively moved in and out of an outlet to limit or prevent vapor flow.

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing, an airflow tube that extends through the reservoir housing, and a folded mesh that is disposed within the airflow tube and includes a plurality of folds. The airflow tube defines a passageway extending therethrough and at least a portion of the airflow tube is permeable to the vaporizable material, in which the permeable portion of the airflow tube is configured to draw vaporizable material from the reservoir housing into the airflow tube for vaporization. The folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize at least a portion of the vaporizable material drawn from the reservoir housing. Vaporizer devices are also provided.
