As shown in fig. 3 and 5, the aerosol-generating device further comprises a heating element 2, the heating element 2 being arranged on an inner side wall of the housing assembly 1, the heating element 2 being adapted to heat and atomize a substrate end of the aerosol-generating article 3 inserted into the heating chamber 4.

The heating temperature of the heating element 2 on the substrate end is typically between 250 ℃ and 350 ℃, and compared with the common combustion, the heating of the non-combustion aerosol-generating article 3 can greatly reduce the harm of harmful substances in the substrate end to a user while maintaining the taste, and the release amount of the harmful substances in the substrate end is reduced because the high-temperature combustion cracking process does not occur, so that the harm is reduced.

The heating element 2 has terminals 21, the terminals 21 extending to the bottom end of the housing assembly 1, the terminals 21 for making electrical connection of the heating element 2, the terminals 21 of the heating element 2 being electrically connected to a main board assembly (not shown in the drawings) through wires 5, so that heating of the heating element 2 can be controlled by the main board assembly. In the practice of the present disclosure, the motherboard component is a printed circuit board (Printed Circuit Board, PCB).

The insulating bush 51 is made of an insulating material, so that the possibility of short circuit during power transmission can be reduced, and the electrical safety of the device can be ensured.

The connection portion between the terminal 21 of the heating element 2 and the lead wire 5 of the conventional aerosol generating device is generally located on the outer side wall of the housing assembly 1, and in the case that the heating element 2 is located on the inner side wall of the housing assembly 1, introducing the terminal 21 of the heating element 2 to the outer side wall of the housing assembly 1 may result in more complicated structure and wiring, and may result in reduced reliability of the heating element 2, and in addition, complicated structure may result in more difficult assembly, and increased production cost.

Therefore, in the embodiment of the present disclosure, the structure of the heating element 2 is optimized such that the connection portion of the wire 5 and the terminal 21 is located on the inner side wall of the housing assembly 1 facing the heating chamber 4, that is, such that the connection portion of the wire 5 and the terminal 21 is disposed on the same inner side wall as the heating element 2, thus simplifying the wiring manner and structure of the heating element, reducing the production cost, and improving the reliability of the heating element 2.

In the embodiment of the disclosure, the fixing support 7 of the aerosol generating device adopts a split structure, the periphery of the supporting disc 72 is in sealing fit with the inner side wall of the housing assembly 1, and the connection part of the wire and the terminal is positioned at the bottom side of the supporting disc, so that even if the connection part of the wire 5 and the terminal 21 of the heating element 2 is positioned on the inner side wall of the housing assembly 1 facing the heating bin 4, the connection part can not influence the sealing of the heating bin 4, and the structure and wiring mode of the heating element are simplified while the good sealing of the heating bin 4 is ensured.

As shown in fig. 6, the support 71 is further provided with a connection structure 713, the connection structure 713 being for connecting the support 71 with other elements of the aerosol-generating device, in the disclosed embodiment the connection structure 713 is a snap. In some other embodiments, the connection structure 713 may also be any other suitable connection structure.

As shown in fig. 2, the top side of the housing assembly 1 has a first opening 11, and the size of the first opening 11 is not smaller than the size of the support plate 72, so that the support plate 72 can be placed into the housing assembly 1 through the first opening 11.

The bottom side of the housing assembly 1 has a second opening 12, and at least a portion of the support bracket 71 is insertable into the housing assembly 1 from the second opening 12 and is connected to the support plate 72.

As shown in fig. 6, the support 71 includes a cylindrical shape and is formed with an annular step surface 714 on a circumferential surface, the step surface 714 is provided with a plurality of projections 712, the plurality of projections 712 are arranged at intervals along the circumferential direction of the step surface 714, and when at least a part of the support 71 is inserted into the housing assembly 1 through the second opening 12, the bottom end surface of the housing assembly 1 abuts against the projections 712 so that the bottom end surface of the housing assembly 1 is arranged at intervals from the step surface 714. The protrusions 712 can reduce the contact area between the bottom end surface of the housing assembly 1 and the support frame 71, thereby increasing thermal resistance, reducing heat conduction from the housing assembly 1 to the support frame 71 and then to other elements in the aerosol-generating device, and improving the reliability of the aerosol-generating device.

In the embodiment of the present disclosure, five protrusions 712 are formed on the supporting frame 71, and in some other embodiments, fewer or more protrusions 712 may be formed on the supporting frame 71, and the number and the size of the protrusions 712 are not specifically limited in the embodiment of the present disclosure, and may be specifically set according to the size of the step surface 714 of the actual supporting frame 71.

And the first circumferential surface 7a and the second circumferential surface 7b are spaced apart along the direction in which the aerosol-generating article 3 is inserted into the heating cartridge 4, the connection point of the wire 5 and the terminal 21 being located between the first circumferential surface 7a and the second circumferential surface 7 b. The support frame 71 is provided with dodges passageway 8, and wire 5 wears to locate in dodging passageway 8.

The above arrangement of the support frame 71 and the support plate 72 of the fixing bracket 7 can facilitate the wiring of the heating element 2, and since the first circumferential surface 7a and the second circumferential surface 7b leave a space therebetween, the fixing bracket 7 can be made to not affect the arrangement of the connection portions of the terminals 21 of the heating element 2 and the wires 5. Meanwhile, the avoidance channel 8 arranged on the support frame 71 is convenient for threading the lead 5, so that the lead 5 does not need to be led out to the outer side wall of the shell assembly 1, the wiring mode and structure of the heating element are simplified, and the reliability of the heating element 2 is improved.

As shown in fig. 3 and 4, the aerosol-generating device comprises a sealing ring 9, the sealing ring 9 being arranged between the first circumferential surface 7a of the support disc 72 and the inner side wall of the housing assembly 1 for effecting a sealing contact of the housing assembly 1 and the support disc 72.

The sealing ring 9 can be, for example, a silicone ring, which has relatively low hardness and good high temperature resistance. In this way, when the seal ring 9 is disposed between the first circumferential surface 7a of the support plate 72 and the inner side wall of the housing assembly 1, it is slightly deformed by the pressing force of both and closely fitted between the first circumferential surface 7a and the inner side wall of the housing assembly 1, thereby reducing the gap between the housing assembly 1 and the support plate 72, and realizing the contact seal. The sealing contact between the housing assembly 1 and the support plate 72 can reduce the possibility of heat escaping from the heating chamber 4, and has good sealing and heat insulating effects.

In the embodiment of the disclosure, when the fixing bracket 7 is assembled with the housing assembly 1, the sealing ring 9 is firstly arranged in the clamping groove 723 of the supporting disc 72, then the supporting disc 72 is placed into the housing assembly 1 through the first opening 11 of the housing assembly 1, and then the supporting frame 71 extends into the housing assembly 1 from the second opening of the housing assembly 1 and is connected with the supporting disc 72. In the disclosed embodiment, the lead 5 and the terminal 21 are connected to each other by soldering. As shown in fig. 3 to 5, a joint portion between the lead wire 5 and the terminal 21 is formed with a solder joint 6. The solder joint 6 can ensure that the connection part of the lead 5 and the terminal 21 is more firmly and stably connected, increase the reliability, and ensure that the electrical contact between the lead 5 and the terminal 21 is good.

In the presently disclosed embodiment, the heating element 2 is a heating film that generates heat when energized, thereby heating the substrate end of the aerosol-generating article 3 inserted into the heating cartridge 4. The heat generating film may be, for example, a metal heat generating film, a conductive ceramic heat generating film, a conductive carbon heat generating film, or the like. The shape of the heating film may be a continuous film shape, a porous net shape, a strip shape, or the like. The embodiments of the present disclosure are not particularly limited in terms of materials and shapes.

In some other embodiments, the heating element 2 may also be any other suitable heating element.

The heating elements 2 are uniformly arranged along the circumferential direction of the inner side wall of the housing assembly 1, so that the substrate end of the aerosol-generating article 3 inserted into the heating chamber 4 can be uniformly heated, and the possibility of uneven heating of the substrate end of the aerosol-generating article 3 is reduced.

As shown in fig. 7, the top wall of the support tray 72 (i.e., the bottom wall of the heating cartridge 4) is formed with a protrusion 722, the protrusion 722 being for contacting with the bottom end portion of the substrate end of the aerosol-generating article 3, so that a space for gas communication is formed between the bottom end portion of the substrate end of the aerosol-generating article 3 and the bottom wall of the heating cartridge 4.

In the embodiment of the present disclosure, five protrusions 722 are formed on the support plate 72, and in some other embodiments, fewer or more protrusions 722 may be formed on the support plate 72, and the number and size of the protrusions 722 are not particularly limited in the embodiment of the present disclosure, and may be specifically set according to the actual size of the support plate 72.

As shown in fig. 3 to 5, the housing assembly 1 of the embodiment of the present disclosure includes a first housing 1a and a second housing 1b, the first housing 1a is sleeved on the outer side of the second housing 1b, and a vacuum area 1c is formed between the first housing 1a and the second housing 1 b. The inner side wall of the second housing 1b defines a heating compartment 4 for receiving a substrate end of the aerosol-generating article 3, and the heating element 2 is arranged on the inner side wall of the second housing 1 b.

When the aerosol-generating device is in operation, heat is generated in the heating chamber 4 to heat and atomize the substrate end of the aerosol-generating article 3 contained therein, and therefore, it is necessary to thermally insulate the heating chamber 4. If the heat insulation effect is not good, heat may be transferred to the outside of the housing assembly 1, and thus, a user may be scalded.

The housing assembly 1 of the embodiment of the present disclosure is provided with the vacuum region 1c, and thus, the vacuum region 1c can transmit as little heat generated in the heating chamber 4 to the first housing 1a (i.e., the outside of the housing assembly 1) as possible, thereby achieving a good heat insulation effect.

In addition, as the shell assembly 1 is provided with the vacuum zone 1c for heat insulation, no additional heat insulation means are needed, so that the number of parts can be reduced, the assembly difficulty is reduced, and the production cost is saved.

Illustratively, the first casing 1a and the second casing 1b may be connected and fixed in a vacuum environment by means of vacuum welding, thereby forming a vacuum region 1c for heat insulation, and at the same time, the vacuum welding may also simplify an assembling process between the first casing 1a and the second casing 1 b.

The distance between the first housing 1a and the second housing 1b (i.e. the width of the vacuum zone 1 c) is between 1mm and 3mm, preferably between 1.5mm and 2mm, in a direction perpendicular to the insertion of the aerosol-generating article 3 into the heating cartridge 4.

Illustratively, the separation distance between the first housing 1a and the second housing 1b may be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or the like.

The first shell 1a and the second shell 1b are cylindrical and concentrically arranged, so that the vacuum area 1c can be uniformly and circumferentially distributed around the heating bin 4, and heat emitted by the heating bin 4 can be uniformly and fully isolated, and a better heat insulation effect is achieved.

In some other embodiments, the first housing 1a and the second housing 1b may also be arranged eccentrically.

Illustratively, the heating chamber 4 may not be located at the center of the housing assembly 1, so that, in the radial direction of the housing assembly 1, the closer to the portion of the heating chamber 4, the greater the spacing distance between the first housing 1a and the second housing 1b may be, that is, the more space occupied by the vacuum region 1c, and the farther from the portion of the heating chamber 4, the smaller the spacing distance between the first housing 1a and the second housing 1b may be, that is, the less space occupied by the vacuum region 1c. Therefore, the heat insulation can be effectively performed on the part with large heating value, and the overall size of the device is reduced while the heat insulation effect is ensured.
