Therefore, through the above technical solution, the aerosol generating device provided by the embodiment of the present utility model can open the open end on the housing assembly 10 by removing the cover assembly 40, so as to remove the battery assembly 30 from the accommodating cavity 13, and realize the disassembly and separation of the battery assembly 30 and the housing assembly 1, so as to recycle the battery assembly 30, and in particular, to facilitate the recycling of the battery cells 32 in the battery assembly 30, thereby being beneficial to environmental protection; in addition, the aerosol generating device provided by the embodiment of the utility model can realize the unlocking and locking of the cover assembly 40 and the shell assembly 10 by rotating the cover assembly 40 relative to the shell assembly 10, and is simple and convenient to operate.

As shown in fig. 4, in some embodiments, the locking structure 50 includes a locking groove 51 recessed in an inner wall of the housing assembly 10 near the open end, and a locking protrusion 52 protruding from an outer wall of the cover assembly 40, the locking groove 51 including an axial channel 511 extending axially from the housing assembly 10, and a circumferential channel 512 extending circumferentially from the housing assembly 10, the axial channel 511 extending through to an outer end surface of the open end of the housing assembly 10, such that when the cover assembly 40 is moved axially, the locking protrusion 52 slides into the axial channel 511 of the locking groove 51, and then the cover assembly 40 is rotated circumferentially, such that the locking protrusion 52 is offset from the axial channel 511 into the circumferential channel 512, such that the locking protrusion 52 cannot slide out of the axial channel 511 relative to the locking groove 51, i.e., such that the cover assembly 40 cannot be moved axially out of the housing assembly 10; in addition, in order to make the locking protrusion 52 not easily swiveled out when entering into the circumferential channel 512, a stopper 513 is provided on a sidewall of the circumferential channel 512 extending in the circumferential direction in the locking groove 51, and when the locking protrusion 52 is fitted into place with the circumferential channel 512, the stopper 513 blocks the locking protrusion 52 from swivelling, and by rotating the locking protrusion 52 by applying a proper force, the locking protrusion 52 presses the stopper 513 to elastically deform the locking protrusion 52 beyond the stopper 513 into the axial channel 511, so as to unlock the locking structure 50. Thus, through the above technical solution, when the cover assembly 40 rotates relative to the housing assembly 10, the cover assembly 40 is mounted on the opening end of the housing assembly 10 or separated from the housing assembly 10 through the locking structure 50, so that the cover assembly 40 opens or closes the accommodating cavity 13, and the battery assembly 30 is mounted or dismounted. It will be appreciated that in other embodiments not shown, the positions of the locking groove 51 and locking tab 52 in the locking structure 50 may be reversed, i.e., the locking groove 51 is located on the closure assembly 40 and the locking tab 52 is located on the housing assembly 10.

Therefore, through the above technical solution, after the first guide portion 341 and the second guide portion 14 are aligned, the first guide portion 341 and the second guide portion 14 slide relatively along the axial direction of the accommodating cavity 13, so as to realize that the battery assembly 30 is axially loaded into the accommodating cavity 13 along the accommodating cavity 13, or is moved out of the accommodating cavity 13, so as to prevent the battery assembly 30 from deflecting in the accommodating cavity 13, and because the battery assembly 30 needs to be aligned and electrically connected with other parts after being loaded into the housing assembly 10, the battery assembly 30 is prevented from deflecting in the accommodating cavity 13, which is beneficial to completing the alignment and the electrical connection.

Because the second traction part 43 can drive the first traction part 35 to axially slide along the accommodating cavity, when the first traction part 35 is matched and clamped with the second traction part 43, the mobile sealing cover assembly 40 can drive the battery assembly 30 to be installed in or removed from the accommodating cavity 13, and the installation and the removal actions of the battery assembly 30 can be completed simultaneously by installing and removing the sealing cover assembly 40, so that the operation is simplified, the efficiency is high, the battery assembly 30 does not need to be poured out after the sealing cover assembly 40 is removed when the battery assembly 30 is removed and recovered, the battery assembly 30 is prevented from being poured out of the accommodating cavity 13 when the battery assembly 30 is tightly matched with the housing assembly 10, and the battery assembly 30 does not need to be taken out by means of a tool; since the second traction portion 43 is rotatable relative to the first traction portion 35, the cooperation of the second traction portion 43 and the first traction portion 35 does not hinder the rotational movement of the cap assembly 40. More precisely, in the present embodiment, the first traction portion 35 has a snap-convex structure, and the second traction portion 43 has a snap-groove structure that mates with the snap-convex structure. It will be appreciated that in other embodiments not shown, the first traction portion 35 may have a snap-in groove configuration and the second traction portion 43 may have a corresponding snap-in protrusion configuration.

Additionally, in some embodiments, when the switch member 42 is rotated from the second position 722 in a direction away from the first position 721 by the second position 722, the switch member 42 drives the fixing base 41 to rotate from the unlocked position to the locked position; when the switch member 42 is rotated from the first position 721 in a direction in which the first position 721 is away from the second position 722, the switch member 42 drives the fixed seat 41 to rotate from the locking position to the unlocking position. This improves the functionality of the switch member 42, and the switch member 42 can be used to control not only the switching of the circuit by the switch assembly 60, but also the locking of the fixing base 41 in the cover assembly 40 to the housing assembly 10 or the unlocking of the fixing base 41 from the housing assembly 10 to remove the battery assembly 30.

In some embodiments, the switch assembly 60 includes a first contact 61, a second contact 62, and a conductive member 63, where the first contact 61 and the second contact 62 are spaced apart, and when the switch member 42 is rotated to a first position 721, the switch member 42 moves the conductive member 63 to separate the first contact 61 and the second contact 62, and when the switch member 42 is rotated to a second position 722, the switch member 42 drives the conductive member 63 to conduct the first contact 61 and the second contact 62.

The elastic force applied to the switch element 42 by the conductive element 63 provides an elastic force for enabling the locking portion 71 on the switch element 42 to be always located in the rotating groove 72 of the fixed seat 41, and the main function is to make the switch element 42 unable to directly rotate to make the locking portion 71 separate from the first position 721 of the open circuit to reach the second position 722 of the close circuit, and it is necessary to push the switch element 42 in the axial direction before rotating the switch element 42 to resist the elastic force of the conductive element 63 to make the locking portion 71 separate from the blocking of the locking body 73, and then rotate the switch element 42 to drive the switch assembly 60 to conduct the circuit, so that an elastic element other than the conductive element 63 is not required to be provided to simplify the structure.
