Referring to fig. 1-2, an aerosol generating device according to an embodiment of the present invention includes a main body 100, an inner bracket 300, and a lid assembly 200 mounted on the main body 100.

The main body 100 comprises a shell 10, a heating body 40 arranged in the shell 10, a mounting frame 20, a face cover 30, a power supply 50, a power supply bracket 51, a control circuit board 60 and a circuit board bracket 61, wherein the power supply 50 is fixedly arranged in the shell 10 through the power supply bracket 51; the circuit board support 61 is positioned at the other side of the power supply 50 relative to the power supply support 51 and is mutually fixed with the power supply support 51 so as to clamp and fix the power supply 50 between the power supply support 51 and the circuit board support 61, the control circuit board 60 is fixedly arranged at the other side of the circuit board support 61 relative to the power supply 50, and a control key 62 connected with the control circuit board 60 is arranged at the position of the shell 10 corresponding to the control circuit board 60; the mounting bracket 20 is fixed in the upper end of the casing 10, preferably, the lower end thereof is fixed in the upper end of the circuit board support 61, and the mounting bracket 20 has a sleeve 21 forming an insertion cavity 22, the heating element 40 is installed in the insertion cavity 22, the lower end thereof is fixed in the bottom wall of the sleeve 21 and is electrically connected with the control circuit board 60, and the control circuit board 60 controls whether the power supply 50 supplies power to the heating element 40; the upper end of the plugging chamber 22 is an open end, and the face cover 30 is fixedly covered on the top end of the mounting frame 20 and is provided with a second insertion hole 31 (shown in fig. 5) correspondingly communicated with the plugging chamber 22.

The inner support bracket 300 is a tubular structure with an open upper end, so that a containing cavity 301 for containing the aerosol-forming substrate 400 is formed, and the bottom wall of the containing cavity is provided with a through hole 302 communicated with the containing cavity 301; the inner bracket 300 is slidably installed in the insertion cavity 22 in the first position and the second position, and the upper end of the heating element 40 is inserted into the receiving cavity 301 through the through hole 302. When the inner support bracket 300 is located at the first position, the bottom wall of the inner support bracket 300 is attached to the bottom wall of the insertion cavity 22 or has a gap, and most of the heating element 40 is inserted into the receiving cavity 301 so as to be in full contact with the aerosol-forming substrate 400 contained in the receiving cavity 301; when the inner support bracket 300 is located at the second position, the bottom wall of the inner support bracket 300 and the bottom wall of the inserting cavity 22 have a certain interval, and at this time, the heating element 40 is partially or completely pulled out of the accommodating cavity 301. When the inner holder 300 slides from the first position to the second position, the inner holder 300 moves away from the heating element 40 (i.e., slides upward), thereby driving the aerosol-forming substrate 400 received in the receiving cavity 301 to move upward for a distance (i.e., a stroke between the first position and the second position) such that the upper end of the heating element 40 is pulled out of at least a portion of the aerosol-forming substrate 400, thereby facilitating separation of the subsequent aerosol-forming substrate 400 from the heating element 40.

It should be noted that the shape of the through hole 302 is adapted to the cross-sectional shape of the heating element 40, and when the inner holder 300 slides between the first position and the second position, the heating element 40 always substantially blocks the through hole 302, so as to reduce the dropping of the tobacco shreds, the scraps and other substances from the aerosol-forming substrate 400 into the plugging chamber 22 through the through hole 302. Preferably, in the present embodiment, the heating element 40 has a needle-like structure, and the corresponding through hole 302 is a circular hole, so that the inner holder 300 can rotate circumferentially; in other embodiments, the heat-generating bodies 40 may be sheet-like bodies, and the number of the heat-generating bodies 40 may be two or more.

The upper cover assembly 200 is connected to the upper end of the inner support frame 300 and slidably mounted to the upper end of the main body 100 in a vertical direction, and when the upper cover assembly 200 slides in the vertical direction with respect to the main body 100, the inner support frame 300 is driven to move between a first position and a second position, and the upper cover assembly 200 is provided with a first insertion hole 203 correspondingly communicated with the receiving cavity 301.

In one embodiment, referring to fig. 3 and 4, fig. 3 is a schematic cross-sectional view of the inner bracket 300 moving to a second position and connecting with the lid assembly 200; fig. 4 is a cross-sectional view of the lid assembly 200 and the inner bracket 300 when they are pulled off. The first pull-off structure 70 is arranged between the upper end of the inner support bracket 300 and the upper cover assembly 200 to realize detachable connection, and when the upper cover assembly 200 is pulled to drive the inner support bracket 300 to move from the first position to the second position and the received pulling force is greater than the pull-off force of the first pull-off structure 70, the upper cover assembly 200 is separated from the inner support bracket 300. Thus, when the upper cover assembly 200 is pulled out of the main body 100, the upper cover assembly 200 is separated from the inner support frame 300, and the inner support frame 300 is still assembled in the insertion cavity 22 of the main body 100, so that the inner support frame 300 is prevented from being pulled out of the main body 100 along with the upper cover assembly 200, and the accommodating cavity 301 of the inner support frame 300 can be conveniently cleaned.

Specifically, the upper cover assembly 200 in the present embodiment includes a cover body 201 that is slidably disposed on the main body 100 and a liner 202 disposed in a lower end of the cover body 201, the cover body 201 is formed with a first insertion hole 203, the liner 202 is formed with a mounting hole 204 coaxially communicating with the first insertion hole 203, and a diameter of the mounting hole 204 is larger than an outer diameter of the inner support bracket 300; the first pull-out structure 70 comprises a first clamping part 71 arranged on the inner support bracket 300 and a first matching part 72 arranged on the inner wall of the mounting hole 204, and the upper end of the inner support bracket 300 can be connected in the mounting hole 204 in a pull-out manner through the matching of the first clamping part 71 and the first matching part 72; in this way, when the pulling force applied to the upper cover assembly 200 is greater than the pulling force between the first retaining portion 71 and the first matching portion 72, the upper end of the inner bracket 300 can be separated from the mounting hole 204, thereby separating the upper cover assembly 200 from the inner bracket 300.

Further, the first retaining portion 71 is a first protruding block formed by protruding the outer wall of the upper end of the inner bracket 300, and the first matching portion 72 is a first annular retaining strip formed by protruding the inner wall of the mounting hole 204; when the upper end of the inner support bracket 300 is clamped into the mounting hole 204, the annular clamping strip is abutted against the lower side of the first bump; the pull-out force of the first pull-out structure 70 is the maximum holding force between the first bump and the first annular strip.

It should be noted that the opposite inner sides of the first protruding block and the first annular clamping strip are both arc surfaces, the distance from the central axis of the inner support bracket 300 to the outer side of the first protruding block is greater than the inner diameter (radius) of the first annular clamping strip, and the number of the first protruding blocks is preferably two or more, and the first protruding blocks are uniformly distributed on the outer wall of the inner support bracket 300; thus, when the first protruding block and the first annular clamping strip abut against each other, an interference fit is formed between the first protruding block and the first annular clamping strip, and an interference magnitude a1 is provided (as shown in fig. 6), so that when a pulling force received by the upper cover assembly 200 is greater than an abutting acting force between the first protruding block and the first annular clamping strip, the first annular clamping strip passes over the first protruding block to separate the inner support bracket 300 from the mounting hole 204, i.e., separation of the upper cover assembly 200 and the inner support bracket 300 is achieved. Moreover, when the upper cover assembly 200 needs to be installed, the first protruding block can pass over the first annular clamping strip and be located above the first annular clamping strip by only facing the installation hole 204 of the upper cover assembly 200 to the upper end of the inner support bracket 300 and pressing downwards with force, so that the upper cover assembly 200 and the inner support bracket 300 can be connected in a pull-out manner again.

In an alternative embodiment, the first retaining portion 71 and the first mating portion 72 are magnetic members magnetically attracted to each other, so as to magnetically connect the upper cover assembly 200 and the inner bracket 300, and the pulling-out force of the first pulling-out structure 70 is the maximum magnetic attraction force between the two magnetic members; when the pulling force received by the cover assembly 200 is greater than the maximum magnetic attraction force of the first pull-off structure 70, the cover assembly 200 may be separated from the inner bracket 300.

In one embodiment, referring to fig. 5, fig. 5 is a cross-sectional view of the main body 100 after the inner bracket 300 is pulled out from the plugging chamber 22. A second pull-out structure 80 is arranged between the outer wall of the inner support bracket 300 and the plugging cavity 22 to realize detachable connection, and the pull-out force of the second pull-out structure 80 is greater than that of the first pull-out structure 70; when the inner support bracket 300 is pulled to move from the first position to the second position and the pulling force applied is greater than the pulling force of the second pulling-out structure 80, the inner support bracket 300 is separated from the plugging cavity 22. So, after upper cover assembly 200 is pulled out and is separated with interior support 300 from main part 100, when treating interior support 300 cooling, usable second draws out structure 80 and draws interior support 300 from grafting chamber 22, realizes the separation of interior support 300 and main part 100, can be convenient for clean the dirty material of the accumulation because of long-time use in grafting chamber 22 this moment to guarantee the aerosol taste.

Further, the second retaining portion 81 is a second protruding block formed by protruding the outer wall of the middle portion of the inner bracket 300, and the second matching portion 82 is a second annular retaining strip formed by protruding the inner wall of the upper end of the inserting cavity 22; when the inner support bracket 300 moves from the first position to the second position, the second bump moves towards the second annular clamping strip until the second bump abuts against the lower side of the second annular clamping strip; the pulling-out force of the second pulling-out structure 80 is the maximum resisting force between the second convex block and the second annular clamping strip, and when the pulling force applied to the inner support frame 300 is greater than the pulling-out force of the second pulling-out structure 80, the second convex block passes over the second annular clamping strip to separate the inner support frame 300 from the inserting cavity 22.

It should be noted that the opposite inner sides of the second protruding block and the second annular clamping strip are both arc surfaces, the distance from the central axis of the inner support bracket 300 to the outer side of the second protruding block is greater than the inner diameter (radius) of the second annular clamping strip, and the number of the second protruding blocks is preferably two or more, and the second protruding blocks are uniformly distributed on the outer wall of the inner support bracket 300; thus, when the second protrusion and the second annular locking strip abut against each other, an interference fit is formed between the second protrusion and the second annular locking strip, and the interference magnitude a2 is provided, and the interference magnitude a2 of the second pull-off structure 80 is greater than the interference magnitude a1 of the first pull-off structure 70 (as shown in fig. 6), so that the pull-off force of the second pull-off structure 80 is greater than the pull-off force of the first pull-off structure 70.

When the pulling force received by the upper cover assembly 200 is greater than the abutting acting force between the second protrusion and the second annular clamping strip, the second protrusion passes over the second annular protruding strip to separate the inner support bracket 300 from the insertion cavity 22, i.e., the inner support bracket 300 is separated from the main body 100. Moreover, when the inner support 300 needs to be installed again, the inner support 300 is only required to be inserted into the insertion cavity 22 and pressed downwards with force, so that the second protruding block can pass over the second annular clamping strip and be located below the second annular clamping strip, and the pull-off connection between the inner support 300 and the main body 100 is realized again.

In the present embodiment, the upper end of the plug cavity 22 expands radially outward and forms the sliding slot 23 together with the surface cover 30, and the edge of the second insertion hole 31 is the second annular clamping strip. It should be understood that the sliding groove 23 in this embodiment is circular, i.e. the inner bracket 300 can rotate around in the inserting cavity 22; when the heating element 40 is in a sheet structure, the sliding groove 23 may have a vertical elongated hole structure, so as to restrict the inner holder 300 from rotating in the circumferential direction.

In an alternative embodiment, the second holding portion 81 and the second matching portion 82 are magnetic members magnetically attracted to each other, so as to magnetically connect the inner supporting frame 300 and the main body 100, and the pulling-out force of the second pulling-out structure 80 is the maximum magnetic attraction force between the two magnetic members; if the first pull-off structure 70 in this embodiment also adopts a magnetic attraction structure, the maximum magnetic attraction force of the second pull-off structure 80 is greater than the maximum magnetic attraction force of the first pull-off structure 70, so that when the upper cover assembly 200 is pulled upwards, when the pulling force is greater than the maximum magnetic attraction force of the first pull-off structure 70, the upper cover assembly 200 is separated from the inner support 300, and the inner support 300 is still connected to the plug cavity 22.

In one embodiment, magnetic members are respectively disposed at the ends of the main body 100 and the upper cover assembly 200 close to each other, specifically, a first magnetic member 91 is disposed between the cover 201 and the liner 202, and a second magnetic member 92 is disposed between the mounting frame 20 and the face cover 30; when the upper cover assembly 200 is assembled to the main body 100, the first magnetic member 91 and the second magnetic member 92 cooperate with each other to generate a magnetic attraction force for driving the upper cover assembly 200 to drive the inner bracket 300 to move from the second position to the first position, so as to ensure the connection stability between the upper cover assembly 200 and the main body 100 when the aerosol generating device is used.
