Preferably, the top cover 114 is attached to the outer shell 112 of the upper housing 11, or the top cover 114 is integrally formed with the outer shell 112 of the upper housing 11.
In some embodiments, the extractor 6 and the heat generating component 12 have a magnetic attraction therebetween, and the extractor 6 is kept connected to the upper housing 11 or detachably connected to the heat generating component 12.
Specifically, referring to fig. 3 and 5, the extractor 6 further includes an extraction portion 62 for extracting the accommodating portion 61, the extraction portion 62 is exposed outside the upper housing 11, and when the extractor 6 is extracted, an extraction force is applied to the lifting portion 132 to extract the extraction portion 62 upward, so that the extractor 6 can move upward, and even disengage from the heat generating component 12 or the upper housing 11; it is not excluded, of course, that the extracting unit 62 is rotated in place by an angle to release the adhesion between the heating element 121 and the smokeable product before the extracting unit 62 is extracted upward, or that the extracting unit 62 is rotated while the extracting unit 62 is extracted upward. The extracting portion 62 is provided with a first insertion opening 621, and the smokeable product is inserted into the accommodating portion 61 through the first insertion opening 621. Referring to fig. 3 and 4, the extracting portion 62 is supported upward by the top cover 114, the extracting portion 62 and the heating element 12 are disposed on the upper and lower sides of the top cover 114, the first magnetic member 51 is disposed inside the extracting portion 62, the second magnetic member 52 is disposed on the heating element 12, and the first magnetic member 51 and the second magnetic member 52 generate a magnetic attraction force, so that the extracting portion 62 presses the top cover 114, and the accommodating portion 61 connected to the extracting portion 62 is held in the fourth accommodating cavity 1243.

The first magnetic member 51 and the second magnetic member 52 may be both magnets, or one of them may be a magnet and the other may be iron or ferromagnetic capable of being attracted by a magnet. If the first magnetic member 51 and the second magnetic member 52 have a sufficiently large magnetic attraction force therebetween, the accommodating portion 61 and the holder 124 may not be in contact with each other, i.e., interference between the accommodating portion 61 and the holder 124 may not be required to increase the insertion and extraction force between the extractor 6 and the heat generating component 12. In some embodiments, as shown in fig. 1, the extractor 6 may be completely detached from the upper housing 11 and the heat generating component 12; in other embodiments, the upper housing 11 and/or the heat generating component 12 are provided with a release mechanism, so that the accommodating portion 61 can only be partially released from the upper housing 11 and the heat generating component 12.
In the embodiment shown in fig. 1, the upper case 11 is detachably attached by screwing the power supply unit 2, and the extracting direction of the extractor 6 coincides with the axial direction of the first accommodating chamber 111, that is, the detaching direction of the upper case 11 with respect to the power supply unit 2 does not coincide with the extracting direction of the extractor 6, so that the upper case 11 cannot be detached from the power supply unit 2 by the force between the extractor 6 and the heat generating module 1 when the extractor 6 is extracted, thereby preventing the upper case 11 from being pulled out by mistake when the extractor 6 is pulled out.

Further, the circuit board 24 is disposed laterally to form the bottom of the mounting cavity 26, thereby saving the inner space of the mounting cavity 26.
In some embodiments, the heat generating component 12 is detachably connected to the upper housing 11, so that when the upper housing 11 is separated from the power module 2 by reverse screwing, a force can be further applied to the upper housing 11, so that the heat generating component 12 can be at least partially separated from the first accommodating cavity 111, and the heat generating component 12 is exposed, so that the heat generating component 12 can be cleaned.
In a further embodiment, the integral structure formed by the holder 124 and the magnetic field generator 123 is detachably connected to the second holder 122, so that the integral structure can be separated from the third receiving cavity 1221, a window is formed in a side wall of the second holder 122, and when the integral structure is separated from the third receiving cavity 1221, the heating body 121 is exposed through the window, so that the heating body 121 can be cleaned, and the inner wall of the holder 124 can be cleaned.
In some embodiments, the heat generating component 12 and the power module 2 may remain connected when the upper housing 11 is detached from the power module 2, such that cleaning of the heat generating component 12 may be accomplished by grasping the lower housing 28 on the power module 2 to bring the cleaning implement into contact with the heat generating component 12.
Referring to fig. 1, 2 and 4, the upper housing 11 is connected to the first bracket 21 by a screw fastener, the second bracket 122 is rotatably connected to the upper housing 11, so that the upper housing 11 can rotate relative to the second bracket 122, in order to prevent the heating element 12 from rotating relative to the first bracket 21 when the upper housing 11 rotates relative to the first bracket 21 to complete the separation or the butt joint, the mounting cavity 26 is provided with a first stop portion 27, and the first stop portion 27 can be connected to the inner side wall of the receiving portion 25 or integrally injection-molded with the receiving portion 25. A second stopping portion 1223 is disposed on the outer side of the base 1222 of the second frame 122, when the second frame 122 is connected to the first frame 21, the first stopping portion 27 and the second stopping portion 1223 cooperate with each other, and the second frame 122 cannot rotate relative to the first frame 21 under the effect that the first stopping portion 27 stops the second stopping portion 1223.
Therefore, when the upper case 11 is rotated relative to the power module to release the turnbuckle connection, there is no angular displacement between the heater module 12 and the power module 2. It is also preferable that the contact force between the upper case 11 and the second supporter 122 is smaller than the coupling force between the second supporter 122 and the first supporter 21, so that the friction or other force between the upper case 11 and the second supporter 122 cannot separate the second supporter 122 from the first supporter 21 when the upper case 11 is separated from the second supporter 122.
Therefore, when the aerosol generating device is disassembled to separate the heating module 1 from the power module 2, the upper housing 11 may be rotated to release the turnbuckle connection between the upper housing 11 and the power module 2, and then the upper housing 11 may be lifted up in the axial direction to contact the connection between the upper housing 11 and the second bracket 122, so that the heating module 12 is separated from the first receiving cavity 111, and the extractor 6 may be separated from the heating module 12 along with the upper housing 11 under the action of the top cover 114, while the heating module 12 is still fixed to the power module 2. Then, the entire structure of at least the holder 124 and the magnetic field heater 123 in the heat generating component 12 is taken out, exposing the heat generating body 121. The corresponding device is then cleaned. Of course, the second bracket 122 may be removed from the power module 2. The assembly sequence is the reverse of the disassembly sequence described above. Preferably, the detachable connection between the first bracket 21 and the second bracket 122 is an interference fit, that is, the second bracket 122 is in an interference fit with the inner wall of the bearing part 25 when inserted into the mounting cavity 26.
In some embodiments, the upper shell 11 and the heat generating component 12 are removably connected, and when the second bracket 122 is pulled downward, the heat generating component 12 can be pulled away from the upper shell 11 along with the second bracket 12, as the upper shell 11 and the second bracket 122 are in interference fit. Through modularization setting upper housing 11, heating element 12, lower casing 28 and power supply module 2, can simplify the process of equipment and disassembling, improve production efficiency.
In the aerosol generating device, the power supply component is detachably connected with the upper shell, so that the heating component can be exposed by detaching the upper shell, and the heating component is convenient to clean; the extraction direction of extractor is different with the split direction of last casing for the extractor can not make by mistake when being extracted and go up casing and power supply module separation, ensures the stability of aerial fog generating device structure.
Go up casing and power supply module detachably and be connected to the convenience is cleaned or is changed the module that generates heat to the heating element.
