In other embodiments, the moving cartridge 4 itself is made of a thermally conductive material, acts as a cartridge-type heating element and is electrically heated for heating the aerosol-generating article 100.

A gap space 30 is arranged between the outer wall of the movable cylinder 4 and the inner wall of the fixed cylinder 3, a sealing slide 7 is arranged between the outer wall of the movable cylinder 4 and the inner wall of the fixed cylinder 3, the sealing slide 7 plays a role in sealing the gap space 30 and sliding, and the sealing slide 7 seals the gap space 30 and enables the movable cylinder 4 to still slide without friction and obstruction, so that the smoothness of moving the movable cylinder 4 is facilitated, and the phenomenon that air flow enters to cause air flow to mix up is avoided. One end of the sealing slide piece 7 is fixed, and one end of the sealing slide piece 7 can be connected to any position, can be connected to the fixed cylinder 3, and can also be connected to other parts except the fixed cylinder; the other end of the sealing slider 7 moves synchronously with the moving cylinder 4, and the other end of the sealing slider 7 can be connected to any position on the moving cylinder 4. In some embodiments, the sealing slider 7 is connected between the moving cylinder 4 and the fixed cylinder 3, and the connection manner between the sealing slider 7 and the moving cylinder 4 and the fixed cylinder 7 respectively includes, but is not limited to, integral molding, bonding, welding, and the like. Further, the sealing slider 7 is detachably connected between the movable barrel 4 and the fixed barrel 3 by means including, but not limited to, by means of a hook, tie, snap, buckle, snap-fit structure, by means of fasteners, etc.

In some embodiments, the sealing slider 7 has a folding structure that is telescopic along the moving direction of the moving cylinder 4, and the folding manner of the folding structure is not limited as long as the required telescopic effect can be generated by folding, and the invention is within the protection scope of the present invention.

The sealing slider 7 may be made of any material as long as it has a retractable folding structure. Since the aerosol-generating article is oily or the like when the aerosol-generating article is sucked by a user and the smoke formed in the housing 1 is cooled and then falls onto the sealing slider 7, the long-term deposition may affect the smoothness of expansion and sliding, the sealing slider 7 is preferably made of a heat-conducting and/or electric-conducting material, and thus heat transfer and heat generation can be realized or heat generation can be realized by electrification, and the deposited smoke oil is evaporated and dissipated. Conductive materials include, but are not limited to, gold, silver, iron, steel, copper, aluminum, nickel, alloys thereof, and the like. The heat conductive material includes, but is not limited to, polymer heat conductive material, metal-filled polymer heat conductive material, carbon-based heat conductive material, and the like, such as carbon black, carbon powder, activated carbon, porous carbon, mesophase carbon microsphere, graphene oxide, reduced graphene oxide, graphite alkyne, carbon nanotube film, carbon fiber film, carbon fiber cloth, polyimide heating film, and the like.

The elastic rubber includes but is not limited to rubber, silicone, elastic plastic, etc. Resilient metals include, but are not limited to, copper, beryllium copper, steel, and the like. Since the aerosol-generating article is oily or the like when the aerosol-generating article is sucked by a user and the smoke formed in the housing 1 is cooled and then falls onto the sealing slider 7, the smoothness of the sliding is affected by the long-term deposition, and therefore, the sealing slider 7 is preferably made of heat-conducting and/or electric-conducting elastic glue or elastic metal, so that heat transfer and heat generation can be realized or heat generation can be realized by electrification, and the deposited smoke oil is evaporated and dissipated.

An inner supporting wall 12 is attached to the inner wall of the housing 1, a gap 10 is arranged between the inner supporting wall 12 and the outer wall of the moving cylinder 4, and the gap 10 is communicated with the inner space of the housing 1. Within the mobile cartridge 4 is provided a receiving cartridge 8 for receiving an aerosol-generating product 100, a gap 20 being provided between an outer wall of the receiving cartridge 8 and an inner wall of the mobile cartridge 4, the gap 20 being in communication with the interior space within the housing 1. The air current that gets into by air inlet 11 flows through the space 10 between the outer wall of interior support wall 12 and a removal section of thick bamboo 4, gets into the inner space of casing 1, gets into the clearance 20 between the outer wall that holds a section of thick bamboo 8 and the inner wall that removes a section of thick bamboo 4 again, forms complete air current passageway, because the sealed favourable slider 7 of design, the air current can not get into the clearance space 30 between the outer wall of a removal section of thick bamboo 4 and the inner wall of a fixed section of thick bamboo 3, avoided the air current to scurry and led to the suction experience that influences aerosol generation goods 100, can not influence the smoothness nature that removes a section of thick bamboo 4 normal removal again simultaneously.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
