Abstract: An aerosol-generation device includes a cavity, configured to receive an aerosol-forming substrate; a heater, configured to heat the aerosol-forming substrate received in the cavity; a heat insulation tube, arranged outside the heater, where the heat insulation tube has an inner tube and an outer tube that are arranged along a radial direction of the cavity, and a sealing space is formed between the inner tube and the outer tube; and the sealing space is filled with gas; and a heat insulation layer, arranged between the heater and the heat insulation tube. In this application, the heat insulation layer can reduce radiant heat transfer of the heater, and the heat insulation tube arranged outside the heater can further prevent the heat from being transferred outward, thereby preventing a user from feeling hot due to a high shell temperature of the aerosol-generation device, and improving user experience.

Abstract: An e-cigarette cartridge includes a housing with an air inlet and an air outlet; and the housing is provided with a liquid storage cavity, a porous body, a vaporization cavity, a heating element, a support frame, and a vapor output channel, where the vaporization cavity is in airflow communication with the air inlet; the support frame is constructed to provide the porous body with support and holding; and the vapor output channel includes a first channel part and a second channel part that are formed on the support frame and extend in a width direction of the housing. One end of the first channel part is in communication with the vaporization cavity and the other end is in communication with the air outlet; one end of the second channel part is in airflow communication with the vaporization cavity and the other end is in airflow communication with the air outlet.

Abstract: The present application relates to the field of smoking devices, and provides an aerosol generation apparatus and an infrared heater. The aerosol generation apparatus comprises a chamber used for receiving an aerosol-forming substrate; and at least one infrared heater configured to radiate infrared rays to the chamber to heat the aerosol-forming substrate. The infrared heater comprises multiple infrared heating regions used for heating different parts of the aerosol-forming substrate, and predetermined spacing is maintained between adjacent infrared heating regions. The multiple infrared heating regions are configured to be non-independently started.

Abstract: An atomizer of an electronic cigarette includes an outer housing, and the outer housing is internally provided with a liquid storage cavity and an atomization assembly; the atomization assembly includes a first side wall and a second side wall opposite to each other, and an atomization surface extending from the first side wall to the second side wall; a holder is provided within the outer housing, and the holder is provided with a first surface opposite to the atomization surface along the axial direction of the outer housing; and an atomization cavity is formed between the first surface and the atomization surface; and the first surface is configured to be inclined towards the atomization surface along the extension direction of the atomization surface, and is configured to receive a liquid substrate seeped from the atomization assembly and/or condensate formed by condensation of the aerosol within the atomization cavity.

Abstract: The present application provides an aerosol generating device which comprises: a cavity, being configured to receive a smokable material; a heater, being configured to extend along the axial direction of the cavity and at least partially surround the cavity, and being configured to heat the smokable material received in the cavity, a temperature sensor, being kept in the cavity, and being configured to be inserted into the smokable material when the smokable material is received in the cavity to sense the temperature of the smokable material. By adopting the aforesaid aerosol generating device in which the temperature sensor is arranged in the cavity and is capable of being inserted into the smokable material to directly detect the temperature of the smokable material, it is convenient to control the temperature in the heating process and the temperature monitoring in the smoking process is more accurate.
