[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figures 1 to 12As shown, an embodiment of the present invention provides a fresh air device, including: a shell 10, the shell 10 has a accommodating cavity 11 and a fresh air outlet 12 that are interconnected; a blocking portion 20, the blocking portion 20 is arranged in the accommodating cavity 11, and the blocking portion 20 is movably arranged along the extension direction of the fresh air outlet 12, and the blocking portion 20 has a closed position and an open position. When the blocking portion 20 is in the closed position, the blocking portion 20 blocks the fresh air outlet 12, and when the blocking portion 20 is in the open position, the blocking portion 20 and the fresh air outlet 12 are spaced apart to avoid the fresh air outlet 12; a driving portion 30, the driving portion 30 is arranged in the accommodating cavity 11, and the driving portion 30 and the blocking portion 20 are drivingly connected.

[0051] In this embodiment, when the user does not turn on the fresh air device, the blocking portion 20 will block the fresh air outlet 12; when the user turns on the fresh air device, the blocking portion 20 is switched from the closed position to the open position, and the blocking portion 20 moves into the accommodating chamber 11 along the extension direction of the fresh air outlet 12, so that the blocking portion 20 and the fresh air outlet 12 are spaced apart in the axial direction, thereby opening the fresh air outlet 12. By setting the fresh air device, fresh air from the outside is continuously sucked into the room, thereby improving the indoor air quality. The opening and closing of the fresh air outlet 12 is achieved by the blocking portion 20, thereby avoiding the situation where the fresh air outlet 12 is always open, causing dust or fluid to enter the accommodating chamber from the fresh air outlet 12, thereby causing the fresh air device to malfunction; and such a setting improves the aesthetics and automation of the appearance of the fresh air device, and improves the comfort of the user.

[0052] Specifically, when the blocking part 20 moves from the open position to the closed position, it is only necessary to reverse the above process, that is, the blocking part 20 moves in the opposite direction of the extension direction of the fresh air outlet 12, so that the blocking part 20 and the fresh air outlet 12 overlap in the axial direction, thereby achieving the closure of the fresh air outlet 12.

The driving gear assembly 311 is rotatably but immovably arranged on the mounting structure 33. By rotating the driving gear assembly 311, the transmission rack 312 meshed therewith moves in the extension direction of the fresh air outlet 12, thereby driving the blocking part 20 to move in the extension direction of the fresh air outlet 12, thereby realizing the opening and closing of the fresh air outlet 12. In this way, the blocking part 20 is driven to move by the transmission structure of the gear rack, and the mechanism is simple and reliable, the transmission power is large, and the structure has a long service life.
