In detail, the circuitry controls not only the operation of the power supply and heater, but also the operation of other elements in the aerosol-generating device 100. Furthermore, the circuitry may determine whether the aerosol-generating device 100 is operable by examining the status of elements of the aerosol-generating device 100.

Fig. 3-11 are door cover mechanisms provided by embodiments of the present application. The door mechanism 10 includes a housing 11, a movable member disposed in the housing 11, a driving portion, and a bracket 16.

In this example, the housing 11 is removably and fixedly connected to the outer shell of the body 20, including but not limited to a snap-fit connection, a magnetic connection. In other examples, the housing 11 may be integrally formed with the outer shell of the body 20.

As shown in figures 4, 6 and 11, the housing 11 is provided with a receiving hole B, the bracket 16 is provided with a through hole C, and the main body 20 is provided with a chamber 21 for receiving the smokable material; the receiving aperture B, the through aperture C and the chamber 21 are coaxially arranged, through which the smokable material is at least partially received by or removed from the aerosol-generating device 100, and the chamber 21. In other examples, it is also possible that the bracket 16 is not provided with the through hole C.

A movable member configured to be movable with respect to the housing 11 over a first stroke between an initial position and a pressed position, and to be slidable with respect to the housing 11 over a second stroke when moved to the pressed position; the second stroke has a first slide position that opens the receiving hole B and a second slide position that covers the receiving hole B.

In this example, the moveable members include a cover plate 12 and a sliding panel 14. The cover plate 12 is configured to be movable over a first stroke between the initial position and the pressed position, and to be slidable with the slide panel 14 relative to the housing 11 over the second stroke when moved to the pressed position; the sliding stroke of the cover plate 12 and the sliding panel 14 has the first sliding position and the second sliding position; when the cover 12 and the sliding panel 14 are slid together to the second sliding position, the cover 12 may be returned to the initial position. The initial position is a position in which the cover 12 shown in fig. 3 is not depressed, and the second slide position is located at the same position as the depressed position. The direction of the first stroke is substantially perpendicular to the direction of the second stroke.

Specifically, as shown in fig. 6, 8, 9, and 11, the bracket 16 has a slide groove 161, the lower end of the slide panel 14 is fitted into the slide groove 161, one end of the slide panel 14 has a housing chamber 141 protruding toward the inner surface of the cover plate 12, the housing chamber 141 is provided coaxially with the receiving hole B, a part of the compression spring 13 is housed in the housing chamber 141, and the other part of the compression spring 13 abuts against the inner surface of the cover plate 12. Since the compression spring 13 is disposed between the cover plate 12 and the sliding panel 14, when the cover plate 12 and the sliding panel 14 are slid together to the second sliding position, the compression spring 13 may provide a restoring force so that the cover plate 12 may be restored to the initial position. It should be noted that the compression spring 13 is used in this example, and in other examples, other elastic members or components may be used. It should also be noted that in other examples, the bracket 16 may be integrally formed with the housing 11.

When the cover 12 is not pressed down, the cover 12 is at least partially received in the receiving hole B, and the outer surface of the cover 12 is maintained at the same level as the outer surface of the housing 11. Further, as shown in fig. 8, the outer surface of the cover plate 12 has a protrusion 121, and the protrusion 121 is used for receiving a pressing operation and/or a sliding operation of a user. In other examples, the outer surface of the cover 12 may not be provided with the protrusions 121, and it is also possible to provide the outer surface of the cover 12 with a slip-preventing rib instead.

The cover 12 is configured to move up and down along at least a portion of the outer surface of the sliding panel 14. Specifically, the two ends of the cover plate 12 are respectively provided with a guide post 123 and a guide portion 124, the guide portion 124 matches with the shape of the accommodating chamber 141, and the sliding panel 14 is provided with a groove matching with the guide post 123. Thus, the guide post 123 and the guide portion 124 are allowed to move up and down along the outer surface of the slide panel 14.

As shown in fig. 6, when the cover 12 is pressed down, the guide posts 123 and the guide portions 124 cover the outer surface of the sliding panel 14. At this time, if the cover plate 12 is slid leftward, the cover plate 12 can slide along the slide groove 161 together with the slide panel 14, thereby opening the receiving hole B, which is shown in fig. 4 as a first slide position for opening the receiving hole B over the slide stroke of the cover plate 12 and the slide panel 14.

The receiving hole B may be covered when the cover plate 12 slides together with the slide panel 14 rightward along the slide groove 161 from the first slide position shown in fig. 4, and a second slide position covering the receiving hole B on the slide stroke of the cover plate 12 and the slide panel 14 is shown in fig. 2 or 3.

The driving portion is used for generating a force for driving the movable piece to be positioned to the first sliding position or the second sliding position. The driving portion generates a force for driving the movable member to be positioned to the second sliding position, so that the movable member can be returned to the initial position.

Specifically, as shown in fig. 6 and 10, in the present example, the driving portion includes a torsion spring 15. The torsion spring 15 comprises a spring body 151 and two legs extending from the spring body 151, one leg 153 fixed to the lower end of the sliding panel 14, and the other leg 152 fixed to the bracket 16 in the opposite direction; when the cover plate 12 and the slide panel 14 slide together, the torsion spring 15 is deformed to generate an elastic force that drives the cover plate 12 and the slide panel 14 to be positioned to the first slide position or the second slide position.

As shown in fig. 7 to 9, the inner surface of the housing 11 has a guide rail 111 projecting toward the slide panel 14, a guide rail 112, and a stopper portion 113; the protruding distance of the guide rail 112 is greater than that of the guide rail 111, and the length of the guide rail 112 is greater than that of the guide rail 111 along the length direction of the housing 11; the cover plate 12 has an extension portion 122 extending in the width direction of the housing 11, and the slide panel 14 has an extension portion 142 extending in the width direction of the housing 11.

When the cover plate 12 and the slide panel 14 are slid together to the first slide position, the extension 122 can slide along the guide rail 111; when the cover plate 12 and the slide panel 14 are slid together to the second slide position, the cover plate 12 can be disengaged from the guide rail 111. After the cover 12 is separated from the guide rail 111, the cover 12 starts to return to the initial position under the restoring force of the compression spring 13 and the elastic force of the torsion spring 15, and at this time, the extension portion 122 abuts against the limiting portion 113, the limiting portion 113 limits the cover 12, and the outer surface of the cover 12 and the outer surface of the housing 11 are maintained on the same horizontal plane. And when the cover plate 12 and the sliding panel 14 are slid together to the first sliding position or the second sliding position, the extension 142 of the sliding panel 14 is slid along the guide rail 112 all the time.

Referring to fig. 11 again, the bracket 16 has a stop portion 162 and a stop portion 163;

the stopper portion 162 is used for stopping the sliding panel 14 when the sliding panel 14 slides to the first sliding position; the stopper 163 is used to stop the slide panel 14 when the slide panel 14 is slid to the second slide position.

To sum up, since the compression spring 13 and the protrusion 121 are coaxially disposed, the pressing force generated by the pressing operation and the restoring force generated by the compression spring 13 are substantially maintained on the same vertical line, and the guide post 123 and the guide portion 124 are coated on the outer surface of the sliding panel 14, so that the cover plate 12 moves up and down along the outer surface of the sliding panel 14, thereby ensuring that the cover plate 12 does not deflect relative to the sliding panel 14, and further avoiding the stuck phenomenon caused by the deflection. The cover 12 is limited by the guide rail 111 and the limiting part 113, so that the cover 12 is not scratched on the inner surface of the housing 11 during sliding, and the outer surface of the cover 12 is maintained at the same level as the outer surface of the housing 11. The slide panel 14 is constrained by the guide rails 112 and does not deflect relative to the housing 11. The torsion spring 15 provides an elastic force for driving the cover plate 12 and the sliding panel 14 to be positioned to the first sliding position or the second sliding position, and the structure is simple, so that the problem of space limitation of the aerosol-generating device 100 is solved.

Fig. 12-13 illustrate another door mechanism provided in accordance with an embodiment of the present disclosure. The differences from fig. 3 to 11 are:

the driving part includes a magnetic member 251, a magnetic member 252, and a magnetic member 253, the magnetic member 251 is fixed to the cover plate 12 or the sliding panel 14 (in this example, the magnetic member 251 is riveted to the cover plate 12), the magnetic member 252 is fixed to the sliding panel 14, and the magnetic member 253 is fixed to the bracket 16; when the cover plate 12 and the sliding panel 14 are slid together to the first sliding position, the

magnetic members

251 and 253 attract each other to generate an attraction force that drives the cover plate 12 and the sliding panel 14 to be positioned to the first sliding position; when the cover 12 and the sliding panel 14 are slid together to the second sliding position, the

magnetic members

252 and 253 repel each other to generate a repulsive force that drives the cover 12 and the sliding panel 14 to be positioned to the second sliding position, and the repulsive force simultaneously returns the cover 12 to the initial position. In this example, the magnetic member 251 may be a vehicle-mounted iron, and the magnetic member 252 may be a magnet having the same polarity as the magnetic member 253.

One end of the sliding panel 14 is provided with a movable hole, and the cover plate 12 is provided with a movable column corresponding to the movable hole; the cover plate 12 is movable up and down along the movable hole and the outer surface of the receiving chamber 141.

Fig. 14-15 are further door cover mechanisms provided in embodiments of the present application. The differences from fig. 3 to 11 are:

the moveable member 22 is an integrally formed component; the driving part comprises a magnetic element 351 and a magnetic element 352 which have the same magnetic poles and are correspondingly arranged, and the magnetic element 352 is riveted on the movable element 22; when the movable piece 22 is pressed down, the movable piece can slide to the left to the first sliding position, and the magnetic piece 351 and the magnetic piece 352 repel each other to provide a repulsive force positioned at the first sliding position, so that the receiving hole B is opened; when the movable member 22 slides to the second sliding position, the movable member 22 returns to the initial position under the repulsive force of the magnetic member 351 and the magnetic member 352. As can be seen, the magnetic member 352 is biased to the position of the magnetic member 351 in the direction of the second stroke in the first sliding position or the second sliding position, so that the magnetic member 351 generates a repulsive force for driving the movable member 22 to be positioned in the first sliding position or the second sliding position.

It should be noted that the door mechanism described above is applied to the aerosol-generating device, and can be easily imagined, and the door mechanism is not limited to this case. For example: the door mechanism may be applied to cigarette packs or other devices.
