A housing space 20 into which the aerosol-generating substrate 9 is inserted is formed in the case 1. The aerosol-generating substrate 9 may be a cigarette, which may include an overwrap 91 and an aerosol-generating substrate 92 disposed in a bottom portion of the overwrap 91. Wherein, the outer covering layer 91 can be outer covering paper, and the atomizing substrate 92 can be solid sheet or filiform grass leaves. The upper end of the heating element 3 can extend into the accommodating space 20 and be inserted into the atomized substrate 92 of the aerosol generating substrate 9, and the atomized substrate 92 is baked and heated to form aerosol for a user to suck. It will be appreciated that the aerosol generating device is not limited to a square cylindrical shape, and may be other shapes such as a cylindrical shape.

The housing 1 may be substantially rectangular in shape, and a tubular extraction tube 2 may be disposed longitudinally within the housing 1. The extraction tube 2 can be assembled with the top wall of the housing 1, and the inner wall surface of the extraction tube 2 defines a housing space 20. In other embodiments, the extraction tube 2 may also be integrally formed by extending downward from the top wall of the housing 1.

The shape of the socket 210 corresponds to the shape of the cross section of the heating body 3, and the size of the cross section of the socket 210 may be slightly larger than that of the heating body 3, so that the heating body 3 is in clearance fit with the socket 210 to facilitate the insertion of the heating body 3. In the present embodiment, the heat-generating body 3 is in the form of a sheet, and the socket 210 is a rectangle having a cross-sectional dimension slightly larger than that of the heat-generating body 3. The aerosol generating device may further include a heating base 30 on which the heating body 3 is mounted, and the lower end of the heating body 3 may be inserted into the heating base 30.

The pressing member 4 is movably fitted to the outer periphery of the aerosol substrate 92 and is movable back and forth between a first position and a second position with respect to the housing space 20. Wherein, when the pressing piece 4 is at the first position, the pressing piece 4 is not in contact with the aerosol generating substrate 9 or is in contact with the aerosol generating substrate 9 but does not apply pressure to the aerosol generating substrate 9, and the aerosol generating substrate 9 is not deformed or slightly deformed. When the pressing piece 4 is in the second position, the pressing piece 4 presses the aerosol-generating substrate 9, and the aerosol-generating substrate 9 is pressed and deformed, so that the friction force between the outer cladding 91 and the aerosol-generating substrate 92 increases. Preferably, the moving direction of the pressing member 4 is perpendicular to the thickness direction of the heating element 3, so that the atomized substrate 92 can be separated from the heating element 3 while the friction force between the outer cladding 91 and the atomized substrate 92 is increased, and the pulling-out is facilitated. In other embodiments, the movement direction of the pressing member 4 and the thickness direction of the heating element 3 may be set at an acute angle, not parallel to the thickness direction.

Specifically, there may be two pressing members 4, and the two pressing members 4 are respectively provided on two opposite sides of the heat-generating body 3 in the width direction. Two openings 220 communicating the inside and the outside are formed in the side wall of the extraction tube 2 in correspondence with the two pressing members 4, respectively, so that the aerosol-generating substrate 9 can be pressed through the openings 220 to press the aerosol-generating substrate 92 when the pressing members 4 are moved inwardly.

The moving direction of the button 5 is consistent with the moving direction of the pressing piece 4, and the pressing piece 4 can be pushed to move inwards to clamp the aerosol generating substrate 9 by pressing the button 5 inwards. The button 5 may be separately manufactured from the pressing member 4 and then assembled together, or the button 5 may be integrally formed with the pressing member 4. It is understood that in other embodiments, the number of the buttons 5 and the pressing members 4 may be one or more than two. In other embodiments, the movement of the pressing member 4 may be driven by other driving mechanisms such as a wedge, a rack and pinion, a lever, etc., and in this case, the movement direction of the pressing member 4 may also be at an angle to the movement direction of the driving mechanism.

The other two opposite sides of the bracket 6 are respectively provided with a guide shaft 61, the extending directions of the two guide shafts 61 are parallel to the moving direction of the pressing member 4, the two guide shafts 61 are respectively positioned at two sides of the communication port 60 and the opening 220, and the two opposite sides of the main body part 41 of the pressing member 4 are respectively slidably sleeved on the two guide shafts 61. The guide shaft 61 may be formed integrally with the bracket 6, or may be separately manufactured and assembled with the bracket 6. The four corners of the inner side surface of the main body portion 41 can also be respectively protruded to form a limiting portion 43, and the four limiting portions 43 can be movably hooked in the four corners of the communication port 60 respectively, so as to prevent the pressing member 4 from being removed. The bracket 6 can also be fixed on the shell 1 in a buckling connection mode, in the embodiment, a buckle 63 is formed on the outer side wall of the bracket 6 in a protruding mode, a clamping groove is formed on the shell 1 corresponding to the buckle 63, and the bracket 6 and the shell 1 are buckled with each other through the buckle 63 and the clamping groove.

In other embodiments, the pressing element 4 can also be reset from the second position to the first position by means of a manual reset, so that the spring element 7 can also be omitted.

As shown in fig. 3, when the elastic member 7 is in a natural state without external force, the pressing member 4 is in the first position, and at this time, after the aerosol-generating substrate 9 is loaded into the housing space 20 from the top of the housing 1, the pressing member 4 is not in contact with the outer cover 91 or does not contact with the outer cover 91 but does not apply pressure to the aerosol-generating substrate 9, the aerosol-generating substrate 9 is not deformed or slightly deformed, and the heating element 3 heats the aerosol substrate 92 after being energized to generate heat, thereby generating aerosol for the user to inhale.

After the aerosol-generating substrate 9 is heated, the atomized substrate 92 shrinks, resulting in a reduction in the frictional force between the outer cover 91 and the atomized substrate 92, and if the aerosol-generating substrate 9 is pulled out directly, the atomized substrate 92 will adhere to the heating body 3. As shown in fig. 5, in order to prevent the aerosol-generating substrate 92 from sticking to the heating element 3 during pulling, the user may press the button 5 inward, so that the pressing member 4 moves inward to clamp the aerosol-generating substrate 9, the outer cover 91 moves inward to contact the aerosol-generating substrate 92, the friction between the outer cover 91 and the aerosol-generating substrate 92 increases, and the aerosol-generating substrate 9 may be pulled out by hand while being pressed, so that the entire aerosol-generating substrate 9 including the aerosol-generating substrate 91 may be pulled out together.
