In an embodiment, the second limiting member switches between the engaged state and the disengaged state by engaging an electromagnet with an armature, and optionally, the second limiting member includes: a second electromagnet 57 provided in the second housing 51; and a second armature 56 provided in the second housing 51, the second driving friction plate 53 and the second driven friction plate being provided between the second electromagnet 57 and the second armature 56. When the second electromagnet 57 is energized, the second armature 56 is attracted, so that the second armature 56 moves toward the second electromagnet 57, and the second armature 56 pushes against the second driving friction plate 53 or the second driven friction plate 55, so that the second driving friction plate 53 and the second driven friction plate 55 are abutted against each other, thereby forming the engaged state. When the second electromagnet 57 is de-energized, the second armature 56 and the second electromagnet 57 are separated from each other, and the second driving friction plate 53 and the second driven friction plate 55 are separated from each other, so that the second limiting member is in the separated state. Alternatively, the second electromagnet 57 may include a second coil 571 and a second iron core 572 cooperating with the second coil 571.

Further alternatively, an elastic member may be disposed between the second driving friction plate 53 and the second driven friction plate 55, and the elastic member may be a spring or the like. When the second driven friction plate 55 abuts against the second driving friction plate 53, the second driven friction plate 55 and the second driving friction plate 53 press the elastic member, so that the elastic member is in a contracted state. In the engaged state, the second driving friction plate 53 and the second driven friction plate 55 are pressed against each other by the second armature 56 and the second electromagnet 57. When the second electromagnet 57 is de-energized, the acting force disappears, and the elastic member can generate elastic thrust to the second driving friction plate 53 and the second driven friction plate 55, so that the second driving friction plate 53 and the second driven friction plate are rapidly separated.

Due to the fact that the first clutch 40 is matched with the second clutch 50, synchronous driving of the main wind wheel 11 and the fresh air wind wheel 23 can be achieved, and only one of the main wind wheel 11 and the fresh air wind wheel 23 can be driven according to needs. The second rotating shaft of the fresh air wind wheel 23 can be further provided with a gearbox 30 for adjusting the rotating speed of the fresh air wind wheel 23, so that the fresh air device 20 can operate according to a preset state.

The second clutch has a joint state and a separation state, when the second clutch 50 is in the joint state, the motor 60 can sequentially pass through the main wind wheel 11 and the second clutch 50 to be in driving connection with the fresh wind wheel 23, and at the moment, the motor 60 can simultaneously drive the main wind wheel 11 and the fresh wind wheel 23 to rotate. When the second clutch 50 is in the separation state, the main wind wheel 11 is disconnected with the fresh wind wheel 23, at this time, the motor 60 can drive the main wind wheel 11 to rotate, and the fresh wind wheel 23 is disconnected with the main wind wheel 11 and does not rotate.
Referring to fig. 12, further optionally, the second clutch 50 includes:
a second housing 51; the second housing 51 forms an outer shell of the second clutch 50, and the second housing 51 is formed with a through hole into which the primary wind wheel 11 and the second rotating shaft 24 are inserted.
The second driving part 52 is arranged on the second shell 51 and used for connecting the primary wind wheel 11, and a second driving friction plate 53 is arranged on the second driving part 52; the primary wind wheel 11 extends into the second shell 51 and is connected with the second active part 52.
The second driven part 54 is arranged on the second shell 51 and is used for connecting the fresh air wind wheel 23, and the second driven part 54 is provided with a second driven friction plate 55; the second driven part 54 is provided with a second driven shaft hole 541, and the second rotating shaft 24 of the fresh air wind wheel 23 is inserted into the second driven shaft hole 541 and is fixedly connected with the second driven part 54. The second driving friction plate 53 and the second driven friction plate 55 are positioned to correspond to each other such that the second driving element 52 and the second driven element 54 are connected to each other when the second driving friction plate 53 and the second driven friction plate 55 abut against each other. When there is a gap between the second driving friction plate 53 and the second driven friction plate 55, the second driving member 52 and the second driven member 54 are brought into a disconnected state from each other.
And a second limiting member provided in the second housing 51, the second limiting member having a joint state of pushing the second driving friction plate 53 and the second driven friction plate 55 to be joined to each other, and a separation state of separating the second driving friction plate 53 and the second driven friction plate 55 from each other. The second limiting member is configured to push the second driving friction plate 53 and the second driven friction plate 55 to approach each other, so that the second driving friction plate 53 and the second driven friction plate 55 abut against each other, the second limiting member forms the engagement state, at this time, the second driving member 52 and the second driven member 54 are connected and fixed to each other through the second driving friction plate 53 and the second driven friction plate 55 abutting against each other, and the rotation of the main wind wheel 11 can be transmitted to the second rotating shaft 24 through the second clutch 50, so as to drive the fresh wind wheel 23. When the acting force of the second limiting member acting on the second driving friction plate 53 and the second driven friction plate 55 disappears, the second driving friction plate 53 and the second driven friction plate 55 will gradually get away from each other due to the centrifugal force, and the second limiting member forms the separated state, so that the torque of the main wind wheel 11 cannot be transmitted to the second rotating shaft 24. The second limiting member may adopt the structural form described in the foregoing embodiment, and is not described in detail.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
