That is, the aerosol generating device 100 according to the embodiment of the present application does not need to control the dust cap 31 in a manual manner, but uses the first magnetic attraction member 41 and the dust cap assembly 30 to cooperate to drive the dust cap 31 to automatically open or close the opening 12a, so that the dust cap 31 does not need to be controlled by separately setting an exposed manual operation position on the housing 10, the housing 10 is neat in appearance and better in integrity, the state of the dust cap 31 opening or closing the opening 12a is not affected when the aerosol generating device falls accidentally, the reliability of the dust cap 31 is higher, and the dust cap 31 can automatically open or close the opening 12a, so that the automation degree is high, and the science and technology sense is higher while the aerosol generating device is convenient for a user to use.

In one embodiment, referring to fig. 1 to 5, the dust cap assembly 30 includes a second magnetic member 32 disposed on the dust cap 31, where the dust cap 31 is movable in the installation space 100a, corresponding to the second magnetic member 32 being movable in the installation space 100a, and the first magnetic member 41 is disposed in the installation space 100a, and the first magnetic member 41 and the second magnetic member 32 cooperate to selectively open or close the opening 12a by the dust cap 31.

It can be understood that when the first magnetic attraction piece 41 and the second magnetic attraction piece 32 attract each other, the second magnetic attraction piece 32 is attracted to the first magnetic attraction piece 41, so that the dust cover 31 is attracted to the first magnetic attraction piece 41, when the first magnetic attraction piece 41 and the second magnetic attraction piece 32 become repulsive, a repulsive force is generated between the second magnetic attraction piece 32 and the first magnetic attraction piece 41, so that the dust cover 31 is driven to move towards the side far away from the first magnetic attraction piece 41, and under the limitation of the installation space 100a and the repulsive force, the dust cover 31 is positioned at the side far away from the first magnetic attraction piece 41 and keeps the state; when the first magnetic attraction piece 41 and the second magnetic attraction piece 32 become attraction again, the repulsive force between the second magnetic attraction piece 32 and the first magnetic attraction piece 41 becomes attraction, and the second magnetic attraction piece 32 pulls the dust cover 31 to move to the side close to the first magnetic attraction piece 41 until the second magnetic attraction piece 32 is attracted to the first magnetic attraction piece 41, and the attraction generated by attraction of the first magnetic attraction piece 41 and the second magnetic attraction piece 32 can ensure that the dust cover 31 is always located on the side close to the first magnetic attraction piece 41. As such, the dust cover 31 has two different positional states located on the side away from the first magnetic attraction piece 41 and on the side close to the first magnetic attraction piece 41, which can open the opening 12a or close the opening 12a, respectively.

It should be noted that, when the first magnetic attraction member 41 and the second magnetic attraction member 32 attract each other, the dust cover 31 may be driven to close the opening 12a, and when the first magnetic attraction member 41 and the second magnetic attraction member 32 repel each other, the dust cover 31 may be driven to open the opening 12a.

The first magnetic attraction piece 41 and the second magnetic attraction piece 32 may be attracted to drive the dust cover 31 to open the opening 12a, and the first magnetic attraction piece 41 and the second magnetic attraction piece 32 may be repelled to drive the dust cover 31 to close the opening 12a.

In an embodiment, please continue to refer to fig. 1 to 5, one of the first magnetic attraction piece 41 and the second magnetic attraction piece 32 is a first electromagnet, the other is a permanent magnet, the first electromagnet can be controlled in an electric control manner, and further the first magnetic attraction piece 41 and the second magnetic attraction piece 32 can be controlled to be switched between a repulsive state and a attractive state, so that the opening 12a or the opening 12a can be opened by the dust cover 31 can be electrically controlled, which is equivalent to realizing electrification and automation of the dust cover 31, increasing the feeling of science and technology, and being more convenient for users to use and having higher experience.

Specifically, the first magnetic attraction member 41 may be provided as a first electromagnet, and the second magnetic attraction member 32 may be a permanent magnet, so that the first electromagnet is relatively fixed in the installation space 100a, the first electromagnet does not need to reciprocate in the installation space 100a, and an electrical connection line corresponding to the first electromagnet may be stably installed, so that the reliability of the first electromagnet may be increased.

The manner of changing the attractive state between the first magnetic attraction piece 41 and the second magnetic attraction piece 32 to the repulsive state or the repulsive state to the attractive state is not limited, and in an exemplary embodiment, the first electromagnet and the permanent magnet repel each other in a state where the target magnetic pole of the first electromagnet faces the permanent magnet; the first electromagnet attracts the permanent magnet with the non-target magnetic pole of the first electromagnet facing the permanent magnet.

In the embodiment of the present application, the target magnetic pole of the first electromagnet refers to the same magnetic pole as the magnetic pole of the permanent magnet facing the first electromagnet, and the non-target magnetic pole of the first electromagnet refers to a magnetic pole different from the magnetic pole of the permanent magnet facing the first electromagnet.

It is understood that the first electromagnet is disposed opposite to the permanent magnet, the permanent magnet can set the south pole or the north pole toward the first electromagnet, the first electromagnet generates magnetism under the energized state, when the magnetic pole of the first electromagnet toward the permanent magnet is the same as the magnetic pole of the permanent magnet toward the first electromagnet, the first electromagnet repels the permanent magnet, when the first electromagnet needs to attract the permanent magnet, the direction of the current passing through the first electromagnet can be changed, the magnetic pole of the first electromagnet toward the permanent magnet can become a non-target magnetic pole, and the first electromagnet attracts the permanent magnet. By changing the magnetic pole of the first electromagnet toward one side of the permanent magnet, the first electromagnet and the permanent magnet can be controlled to be mutually switched between attraction and repulsion, and the first electromagnet and the permanent magnet interact in the process of opening the opening 12a or closing the opening 12a by the dust cover 31, so that the reliability is high.

It should be noted that the manner of controlling the south pole and the north pole of the first electromagnet is not limited, and for example, the north/south pole switching may be implemented by a circuit and a software design.

The manner in which the user activates the first electromagnet or switches the magnetic pole of the first electromagnet toward the permanent magnet is not limited, and may be implemented, for example, by a button, a gesture, or unlocking a fingerprint.

In some embodiments, the first electromagnet repels the permanent magnet in an energized state and loses magnetism in a de-energized state, which may be magnetized by the permanent magnet and thereby attracted by the permanent magnet. The first electromagnet is powered on and powered off to switch the attractive or repulsive states between the first electromagnet and the permanent magnet, the first electromagnet is not required to be powered on in the whole process, and energy is relatively saved.

Specifically, in general, the time for the user to use the aerosol-generating device is less than the time for the user to use the aerosol-generating device without using the aerosol-generating device, the first electromagnet and the permanent magnet may be set to repel each other in the energized state, so as to drive the dust cover 31 to open the opening 12a, that is, the first electromagnet is energized to drive the dust cover 31 to open the opening 12a when the user uses the aerosol-generating device, the aerosol-generating substrate may extend into the accommodating groove 11a, and the first electromagnet is de-energized when the user does not use the aerosol-generating device, and the permanent magnet adsorbs the first electromagnet to drive the dust cover 31 to close the opening 12a. In this way, the first electromagnet needs to be energized only for a small amount of time when the aerosol-generating device 100 is in use, thereby enabling maximum energy savings.

In an embodiment, please continue to refer to fig. 1 to 5, the first magnetic attraction piece 41 is a second electromagnet, and the second magnetic attraction piece 32 is a third electromagnet, so that the first magnetic attraction piece 41 and the second magnetic attraction piece 32 can both realize electric control, so that the first magnetic attraction piece 41 and the second magnetic attraction piece 32 can be switched between attracted or repelled states.

It should be noted that, the manner of controlling the second electromagnet and the third electromagnet to be in the attracted or repelled state is not limited, for example, in an embodiment, when the magnetic pole of the second electromagnet facing the third electromagnet is controlled to be the same as the magnetic pole of the third electromagnet facing the second electromagnet, the second electromagnet and the third electromagnet repel, and when one of the magnetic poles is changed so that the magnetic pole of the second electromagnet facing the third electromagnet is different from the magnetic pole of the third electromagnet facing the second electromagnet, the second electromagnet attracts the third electromagnet, so that only the direction of the current passing through the second electromagnet and the third electromagnet needs to be controlled, the magnetic poles of the second electromagnet and the third electromagnet can be switched, the first magnetic attraction piece 41 and the second magnetic attraction piece 32 do not need to be installed in a specific direction, the stability of the control is high, and the first magnetic attraction piece 41 and the second magnetic attraction piece 32 can be controlled individually, so that the driving force direction between the two can be changed, so as to drive the dust cap 31 to open or close the opening 12a.

In some embodiments, when the second electromagnet and the third electromagnet are in mutually exclusive states, any one of the second electromagnet and the third electromagnet can be powered off, the other electromagnet continuously keeps in an electrified state, the second electromagnet or the third electromagnet after power off loses magnetism and is magnetized by the other electromagnet and then attracted, and the state switching can be completed by controlling the power on and the power off of the second electromagnet and the third electromagnet in such a way, so that the control is relatively simple.

In still other embodiments, referring to fig. 7 and 8, the dust cap assembly 30 includes an elastic reset member 33, one end of the elastic reset member 33 is connected to the second electromagnet, and the other end is connected to the dust cap 31 or the third electromagnet, where the second electromagnet and the third electromagnet repel each other in the energized state, the dust cap 31 moves relatively, so that the elastic reset member 33 elastically deforms, and when the second electromagnet and the third electromagnet are in the de-energized state, the interaction force between the second electromagnet and the third electromagnet disappears, and at this time, the elastic reset member 33 resumes the elastic deformation, driving the third electromagnet to move toward the second electromagnet, and further pulling the dust cap 31 to move toward the second electromagnet. In this way, when the second electromagnet and the third electromagnet are in the power-off state, the elastic reset piece 33 is utilized to drive the dust cover 31 to move, so that the energy is relatively saved.

It should be noted that, when the second electromagnet and the third electromagnet repel each other, the dust cap 31 is driven to close the opening 12a, and when the elastic restoring member 33 restores the elastic deformation, the dust cap 31 is driven to open the opening 12a.

The second electromagnet may be used to drive the dust cap 31 to open the opening 12a when the second electromagnet is repelled from the third electromagnet, and drive the dust cap 31 to close the opening 12a when the elastic restoring member 33 restores the elastic deformation.

In an embodiment, referring to fig. 1, 4, 5, 7 and 8, the first magnetic attraction piece 41 is a first electromagnet, the first magnetic attraction piece 41 is disposed in the installation space 100a, the dust cover assembly 30 includes an elastic reset piece 33, and two ends of the elastic reset piece 33 are respectively connected with the first electromagnet and the dust cover 31; when the first electromagnet is in the energized state, the first electromagnet generates magnetism, the dust cover 31 is attracted to move towards the first electromagnet, the elastic reset piece 33 is elastically deformed, when the first electromagnet is in the deenergized state, the first electromagnet is in a vanishing state, the elastic reset piece 33 is restored to be elastically deformed, and the dust cover 31 is pushed to move towards one side far away from the first electromagnet. The first electromagnet and the elastic reset piece 33 are used for controlling the movement of the dust cover 31, the structure is relatively simple, the dust cover 31 can be driven to open the opening 12a or close the opening 12a only by switching the first electromagnet to be in an electrified or powered-off state, the control is simple, the first electromagnet does not need to be in an electrified state in the whole process, the service life of the first electromagnet can be relatively prolonged, and energy can be effectively saved.

The dust cap 31 may be made of a magnetizable material, for example, iron, cobalt, nickel, or an alloy thereof.

It should be noted that, the first electromagnet may be in an energized state to drive the dust cap 31 to close the opening 12a, and the elastic restoring member 33 may be used to drive the dust cap 31 to open the opening 12a when elastic deformation is restored.

The first electromagnet may be in an energized state to drive the dust cap 31 to open the opening 12a, and the elastic restoring member 33 may be used to drive the dust cap 31 to close the opening 12a when elastic deformation is restored.

In an embodiment, referring to fig. 1, 3, 6 and 8, a mounting groove 31a is disposed on a side of the dust cover 31 facing the first magnetic attraction member 41, and the second magnetic attraction member 32 matched with the first magnetic attraction member 41 may be disposed in the mounting groove 31a, so that the structure of the dust cover 31 may be effectively utilized, so that the second magnetic attraction member 32 does not occupy excessive space of the accommodating groove 11a, and the structure of the aerosol generating device 100 may be designed more compactly.
