Fig. 3-8 illustrate a covering assembly provided in accordance with a specific example of the present application.

The cover assembly 30 includes a rotating member 31, a movable member 32, a movable member 33, and a fixed base 34.

As will be understood in connection with fig. 5, the rotary member 31 is shaped like a round cap. The upper wall of the rotary piece 31 has a through hole a defining an insertion opening. The inner surface of the upper wall is provided with a boss 31a and a boss 31b. Specifically, the inner surface of the upper wall is partially recessed to form two grooves, the cross sections of the grooves are circular, and the convex columns 31a and the convex columns 31b are arranged in the grooves in a one-to-one correspondence manner. The

bosses

31a and 31b are symmetrically disposed at both sides of the through-hole a. The inner surface of the side wall of the rotary member 31 is provided with a catching groove 31c, and the catching groove 31c is provided near or in communication with the inner surface of the upper wall.

It should be noted that the rotating member 31 may be part of the heating portion 20 or a housing of the aerosol-generating device 100, for example: defined by the (partial or complete) shell of the heating section 20; the rotation member 31 may also be a separate component from the heating portion 20 or the aerosol-generating device 100.

The movable element 32 and the movable element 33 have the same structure, and the movable element 32 and the movable element 33 are symmetrically arranged in the rotating element 31 or on the fixed seat 34. It should be noted that in other examples, it is also possible to provide only one movable member or more than two movable members.

The following description takes the movable element 32 as an example:

as will be understood in conjunction with fig. 6-7, the movable member 32 includes a shutter 321, a swing arm 322, and a magnetic member 323. One end of the shielding piece 321 is connected to the fixing seat 34, the other end of the shielding piece 321 is connected to one end of the swing arm 322, and the other end of the swing arm 322 is connected to the rotating piece 31. It is noted that in other examples it is also possible that one end of the shield 321 is held on the heating portion 20 or the housing of the aerosol-generating device 100.

The shutter 321 includes a body 321a and a connecting shaft 321b. The body 321a has a semicircular shape and a surface thereof facing the heating chamber has a connection member 321c, and the connection shaft 321b has a cylindrical shape and a connection hole.

The swing arm 322 includes a connecting arm 322a and a connecting shaft 322b. The connecting arm 322a has a long bar shape, and has a connecting hole at one end thereof to connect with the connecting member 321 c. The coupling shaft 322b has a cylindrical shape. An upper end (an end facing an inner surface of an upper wall of the rotary 31) of the connecting shaft 322b has a connecting hole to be connected with one of the boss 31a and the boss 31 b; when the connection hole is connected with the boss, the upper end of the connection shaft 322b is held in the groove of the rotary member 31, so that the dislocation of the connection hole and the boss can be prevented; the upper end of the connecting shaft 322b may be inserted into a groove of the inner surface of the upper wall of the rotary member 31. The lower end of the connecting shaft 322b is provided with a receiving chamber for receiving the magnetic member 323, and the magnetic member 323 may be fixed in the receiving chamber by an adhesive material.

As will be understood in connection with fig. 8, the fixing base 34 may be a part of the heating portion 20 or a part of the power supply portion 10 or a separate component. The fixing seat 34 has a through hole B coaxially disposed with the through hole a, and the through hole B is communicated with and coaxial with the heating chamber. The fixing base 34 may be coupled with the rotary member 31. Specifically, the fixing base 34 has a cantilever 341 to be snap-connected with the card slot 31 c; of course, other connection means may be adopted. The upper surface of the fixed base 34 has a protrusion 342 and a protrusion 343 to be connected with the connection hole of the connection shaft 321b and the corresponding connection hole of the movable member 33 in a one-to-one correspondence. The upper surface of the fixing base 34 is partially recessed to form a guide groove 343, and the swing arm 322 is guided to swing back and forth in the guide groove 343. A plurality of receiving grooves are formed in the guide groove 343 to receive the magnetic members. In a preferred embodiment, the guide groove 343 has

accommodating grooves

343a, 343b, 343c for accommodating 3 magnetic elements. For convenience of description, the 2 magnetic members accommodated in the

accommodating grooves

343a and 343c, which have the same magnetism, are referred to as the magnetic members 1 herein; the magnetic member accommodated in the accommodating groove 343b is referred to as a magnetic member 2. The magnetic member 323, the magnetic member 1, and the magnetic member 2 are arranged such that: the magnetic member 323 is magnetically attracted to the magnetic member 1, and the magnetic member 323 is magnetically repelled from the magnetic member 2.

As shown in fig. 9 (where the rotating member 31 is not shown), when the rotating member 31 rotates counterclockwise, the rotating member 31 drives the swing arms of the movable member 32 and the movable member 33 to swing in the guide grooves, so that the swing arms drive the main body of the shielding member to move outward around the shaft (the main body of the shielding member rotates around the connecting shaft of the shielding member). Thus, the through hole a and the through hole B, which were originally blocked by the shutter of the

movable members

32 and 33, are communicated, i.e., the through hole a or the heating chamber is opened.

When the rotating member 31 rotates clockwise, the rotating member 31 drives the movable member 32 and the swing arm of the movable member 33 to swing in the guide groove, so that the swing arm drives the bodies of the shielding members to move inward around the shaft until the bodies of the two shielding members are close to each other. In this way, the through holes a and B are again blocked by the shutter of the

movable elements

32 and 33, i.e. the through holes a or the heating chamber is closed.

In the above operation, due to the arrangement among the magnetic member 323, the magnetic member 1, and the magnetic member 2, the operation is smoother and it is possible to ensure complete closing or opening of the through-hole a or the heating chamber. For example, when the rotating member 31 rotates counterclockwise by more than a half angle, the connecting shaft of the swing arm moves to the upper side of the accommodating groove 343b, and the magnetic member 323 and the magnetic member 2 repel each other at the moment, so that the swing arm can swing toward the position of opening the through hole a or the heating chamber under the repulsive force, the operating force of a user is saved, and the operating hand feeling of the user is improved. When the swing arm moves to a position for opening the through hole A or the heating chamber, the swing arm can be positioned by the attraction force between the magnetic member 323 and the magnetic member 1, and the through hole A or the heating chamber is completely opened. Similarly, the same applies to the clockwise rotation of the rotary member 31.

As can be seen from the above, in the rotation process of the rotating member 31, the magnetic member 323 and the magnetic member 2 form a driving mechanism, which can drive the swing arm to swing; when the rotary member 31 is rotated to a position for opening/closing the through hole a or the heating chamber, the magnetic member 323 and the magnetic member 1 constitute a positioning mechanism capable of being positioned at the position for opening/closing the through hole a or the heating chamber.

It should be noted that it is also feasible to implement the magnetic element 1 as a single magnetic element. It is also possible to implement the drive mechanism and the positioning mechanism using different magnetic members, for example: the driving mechanism is realized by two magnetic pieces, and the positioning mechanism is realized by the other two magnetic pieces.

It should also be noted that the above-mentioned swing arm can also be implemented by using other transmission members, such as: spring arms, hinge links, crank blocks, etc.; movement of the transmission includes, but is not limited to, rotation, linear movement, curvilinear movement, and the like.

Further, the side wall 343d in the guide groove 343 defines a limiting part, which can limit the connecting shaft of the swing arm and limit the counterclockwise rotation angle of the rotating member 31.

It should be noted that the description of the present application and the accompanying drawings set forth preferred embodiments of the present application, however, the present application may be embodied in many different forms and is not limited to the embodiments described in the present application, which are not intended as additional limitations to the present application, but are provided for the purpose of providing a more thorough understanding of the present disclosure. Moreover, the above-mentioned technical features are combined with each other to form various embodiments which are not listed above, and all the embodiments are regarded as the scope described in the present specification; further, modifications and variations may occur to those skilled in the art in light of the foregoing description, and it is intended to cover all such modifications and variations as fall within the scope of the appended claims.
