The power supply may be a rechargeable battery or a disposable battery.
The heater may use a central heating method (a periphery of a heating body or a heat generation body is in contact with an inhalable material) and a peripheral heating method (a heating body or a heat generation body is wrapped around an inhalable material). The heater may further use one or more of the following methods including heat conduction, electromagnetic induction, chemical reactions, infrared effects, resonance, photoelectric conversion, or photothermal conversion to heat the inhalable material to generate an aerosol that can be inhaled.
The circuit may control an overall operation of the aerosol-generation device 100. Specifically, the circuit can control operations of the power supply and the heater, and can also control operations of other elements in the aerosol-generation device 100. In addition, the circuit may check the status of elements in the aerosol-generation device 100 to determine whether the aerosol-generation device 100 can be operated.
FIG. 3 to FIG. 11 show a door mechanism according to an implementation of this application. The door mechanism 10 includes a housing 11 and a movable member, a drive portion, and a holder 16 that are arranged in the housing 11.
In this example, the housing 11 is detachably fixedly connected to a shell of the main body 20. Manners of the connection include, but are not limited to, a buckle connection and a magnetic connection. In other examples, the housing 11 may be integrally formed with the shell of the main body 20.
As shown in FIG. 4 , FIG. 6 , and FIG. 11 , a receiving hole B is provided in the housing 11. A through hole C is provided in the holder 16. A cavity 21 accommodating an inhalable material is arranged inside the main body 20. The receiving hole B, the through hole C, and the cavity 21 are coaxially arranged. Through the receiving hole B, the through hole C, and the cavity 21, the inhalable material is at least partially accommodated in the aerosol-generation device 100 or is removed from the aerosol-generation device 100. In other examples, the holder 16 may not be provided with the through hole C.
The movable member is configured to be movable relative to the housing 11 in a first stroke between an initial position and a press position, and slidable relative to the housing 11 in a second stroke when the movable member moves to the press position. The second stroke has a first slide position for opening the receiving hole B and a second slide position for covering the receiving hole B.
In this example, the movable member includes a cover plate 12 and a slide panel 14. The cover plate 12 is configured to be movable in the first stroke between the initial position and the press position, and is slidable together with the slide panel 14 relative to the housing 11 in the second stroke when the cover plate 12 moves to the press position. The cover plate 12 and the slide panel 14 have a first slide position and a second slide position in a slide stroke. It may be understood that the first slide position or the second slide position may be a limit position in the second stroke and may be a position in a sliding process. When the cover plate 12 and the slide panel 14 slide together to the second slide position, the cover plate 12 is movable to the initial position. The initial position is a position of the cover plate 12 when being not pressed in FIG. 3 , and the second slide position and the press position are the same position. In some examples, a direction of the first stroke is substantially perpendicular to a direction of the second stroke.
Specifically, as shown in FIG. 6 , FIG. 8 , FIG. 9 , and FIG. 11 , the holder 16 has a sliding groove 161. A lower end of the slide panel 14 is inserted in the sliding groove 161. One end of the slide panel 14 is provided with an accommodating chamber 141 protruding toward an inner surface of the cover plate 12. The accommodating chamber 141 and the receiving hole B are coaxially arranged. A part of a compression spring 13 is accommodated in the accommodating chamber 141, and another part of the compression spring 13 abuts against the inner surface of the cover plate 12. Because the compression spring 13 is arranged between the cover plate 12 and the slide panel 14, when the cover plate 12 and the slide panel 14 move together to the second slide position, the compression spring 13 can provide a restoring force to make the cover plate 12 movable to the initial position. It should be noted that, the compression spring 13 is used in this example. In other examples, another elastic member may be used. It should be further noted that, in other examples, the holder 16 may be integrally formed with the housing 11.
When the cover plate 12 is not pressed, the cover plate 12 is at least partially received in the receiving hole B, and an outer surface of the cover plate 12 and an outer surface of the housing 11 remain in the same horizontal plane. Further, as shown in FIG. 8 , the outer surface of the cover plate 12 is provided with a protruding portion 121. The protruding portion 121 is configured to receive a pressing operation and/or a sliding operation of a user. In other examples, the outer surface of the cover plate 12 may not be provided with the protruding portion 121. In an alternative solution, an antiskid protruding bar may be arranged on the outer surface of the cover plate 12.
The cover plate 12 is constructed to be vertically slidable along at least a part of an outer surface of the slide panel 14. Specifically, a guide post 123 and a guide portion 124 are respectively provided at two ends of the cover plate 12. The shape of the guide portion 124 matches the shape of the accommodating chamber 141. A groove matching the guide post 123 is opened in the slide panel 14. In this way, the guide post 123 and the guide portion 124 are vertically movable along the outer surface of the slide panel 14.
As shown in FIG. 6 , when the cover plate 12 is pressed, the guide post 123 and the guide portion 124 are surrounded by the outer surface of the slide panel 14. In this case, if the cover plate 12 is moved left, the cover plate 12 may slide together with the slide panel 14 along the sliding groove 161, thereby opening the receiving hole B. FIG. 4 shows the first slide position for opening the receiving hole B in the slide stroke of the cover plate 12 and the slide panel 14.
When the cover plate 12 and the slide panel 14 slide together from the first slide position shown in FIG. 4 to the right along the sliding groove 161, the receiving hole B may be covered. FIG. 2 or FIG. 3 shows the cover plate 12 and the slide panel 14 in the second slide position that can cover the receiving hole B in the slide stroke.
The drive portion is configured to generate a force that drives the movable member to be positioned to the first slide position or the second slide position. The drive portion generates a force that drives the movable member to be positioned to the second slide position, so that the movable member moves to the initial position.
Specifically, as shown in FIG. 6 and FIG. 10 , in this example, the drive portion includes a torsion spring 15. The torsion spring 15 includes a spring body 151 and two support legs extending from the spring body 151. One support leg 153 is fixed on the lower end of the slide panel 14, and the other support leg 152 is reversely fixed on the holder 16. When the cover plate 12 and the slide panel 14 slide together, the torsion spring 15 is deformed to generate an elastic force that positions the cover plate 12 and the slide panel 14 to the first slide position or the second slide position.
As shown in FIG. 7 to FIG. 9 , a guide rail 111, a guide rail 112, and a limiting portion 113 that protrude toward the slide panel 14 are provided on an inner surface of the housing 11. A protrusion distance of the guide rail 112 is longer than that of the guide rail 111, and the length of the guide rail 112 is larger than that of the guide rail 111 in a length direction of the housing 11. The cover plate 12 has an extending portion 122 extending in a width direction of the housing 11. The slide panel 14 has an extending portion 142 extending in the width direction of the housing 11.
When the cover plate 12 and the slide panel 14 slide together to the first slide position, the extending portion 122 may slide along the guide rail 111. When the cover plate 12 and the slide panel 14 slide together to the second slide position, the cover plate 12 is detachable from the guide rail 111. After the cover plate 12 is detached from the guide rail 111, the cover plate 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. In this case, the extending portion 122 abuts against the limiting portion 113, and the limiting portion 113 limits the cover plate 12, so that the outer surface of the cover plate 12 and the outer surface of the housing 11 remain in the same horizontal plane. When the cover plate 12 and the slide panel 14 slide together to the first slide position or the second slide position, the extending portion 142 of the slide panel 14 keeps sliding along the guide rail 112.
Still referring to FIG. 11 , the holder 16 has a stop portion 162 and a stop portion 163.
The stop portion 162 is configured to stop the slide panel 14 when the slide panel 14 slides to the first slide position. The stop portion 163 is configured to stop the slide panel 14 when the slide panel 14 slides to the second slide position.
In summary, because the compression spring 13 and the protruding portion 121 are coaxially arranged, a pressing force generated by a press operation and the restoring force generated by the compression spring 13 substantially remain on the same axis. The guide post 123 and the guide portion 124 are surrounded by the outer surface of the slide panel 14, so that the cover plate 12 can vertically move along the outer surface of the slide panel 14. Therefore, it can be ensured that the cover plate 12 does not deflect relative to the slide panel 14, thereby avoiding jamming caused by deflection. The cover plate 12 is limited by the guide rail 111 and the limiting portion 113. On one hand, it is ensured that the cover plate 12 is kept from scratching the inner surface of the housing 11 when sliding. On the other hand, it is ensured that the outer surface of the cover plate 12 and the outer surface of the housing 11 remain in the same horizontal plane. The slide panel 14 is limited by a guide rail 112 and is kept from deflecting relative to the housing 11 either. The torsion spring 15 provides an elastic force that positions the cover plate 12 and the slide panel 14 to the first slide position or the second slide position. The structure of the torsion spring is simple, thereby resolving a problem of limited space in the aerosol-generation device 100.
FIG. 12 and FIG. 13 show another door mechanism according to an implementation of this application. A difference from the implementation shown in FIG. 3 to FIG. 11 is as follows:
The drive portion includes a magnetic member 251, a magnetic member 252, and a magnetic member 253. The magnetic member 251 is fixed on the cover plate 12 or the slide panel 14 (in this example, the magnetic member 251 is riveted on the cover plate 12), the magnetic member 252 is fixed on the slide panel 14, and the magnetic member 253 is fixed on the holder 16. When the cover plate 12 and the slide panel 14 slide together to the first slide position, the magnetic member 251 and the magnetic member 253 attract each other to generate an attractive force that positions the cover plate 12 and the slide panel 14 to the first slide position. When the cover plate 12 and the slide panel 14 slide together to the second slide position, the magnetic member 252 and the magnetic member 253 repel each other to generate a repulsive force that positions the cover plate 12 and the slide panel 14 to the second slide position. The repulsive force may simultaneously cause the cover plate 12 to return to the initial position. In this example, the magnetic member 251 may be a ferromagnetic material or a magnet. The magnetic member 252 and the magnetic member 253 may be magnets. The same magnetic poles of the magnetic member 252 and the magnetic member 253 are arranged facing each other.
A movable hole is provided in an end of the slide panel 14. The cover plate 12 has a movable post corresponding to the movable hole. The cover plate 12 is vertically movable along the movable hole and an outer surface of the accommodating chamber 141.
FIG. 14 and FIG. 15 show still another door mechanism according to an implementation of this application. Differences from the embodiment shown in FIG. 3 to FIG. 11 lie in that:
The movable member 22 is an integrally formed component. The drive portion includes a magnetic member 351 and a magnetic member 352 with the same magnetic poles arranged correspondingly. The magnetic member 352 is riveted on the movable member 22. When being pressed, the movable member 22 may slide left to the first slide position, and the magnetic member 351 and the magnetic member 352 repel each other and provide a repulsive force that positions the movable member 22 to the first slide position, thereby opening the receiving hole B. When the movable member 22 slides to the second slide position, the movable member 22 moves to the initial position under the repulsive force of the magnetic member 351 and the magnetic member 352. As can be seen from the figure, the magnetic member 352 is biased toward a position of the magnetic member 351 in the direction of the second stroke in the first slide position or the second slide position, so that the magnetic member 351 generates a repulsive force that positions the movable member 22 to the first slide position or the second slide position.
It should be noted that, the foregoing door mechanisms are all used in an aerosol-generation device, and it is easily conceivable that the door mechanisms are not limited to this case. For example, the door mechanisms may be used in a cigarette box or another device.
