[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second" and "third" are only used for descriptive purposes and are not to be construed as indicating or implying relative importance.

[0021] like Figure 1-4 It is a structural schematic diagram of a wall-mounted fan in a preferred embodiment of the utility model. In this embodiment, a wall-mounted fan includes an exhaust box 2, in which an installation cavity 21 is opened. A plurality of rotating rods 22 are connected to the installation cavity 21 through vertical rotation. The rotation function is realized by the rotating rods 22, and a synchronous frame 24 is horizontally arranged in the middle of the inner wall of the installation cavity 21, and a baffle plate 23 is sleeved on the surface of the rotating rod 22. This structural setting enables the baffle plate 23 to have a flipping function. At the same time, one end of a plurality of connecting blocks 25 are rotatably connected to the surface of the synchronous frame 24, and the other end of the connecting block 25 is fixedly connected to the rear end face of the baffle plate 23. This structural setting can realize the synchronous flipping of the plurality of baffle plates 23, increase the synergy of the flipping between the baffle plates 23, and more effectively realize the function of purifying the air.

[0022] In this embodiment, an exhaust device 3 is provided at the rear end of the exhaust box 2, and the exhaust device 3 is on the same horizontal line as the exhaust box 2. Through the arrangement of this structure, the motor 32 in the exhaust device 3 works to blow air toward the exhaust box 2, so that the baffle 23 is opened under the influence of the wind. The greater the wind force, the greater the flip angle of the baffle 23. If the motor 32 in the exhaust device 3 stops working, the opening area of ​​the baffle 23 is zero, which can effectively prevent the phenomenon of turbid air backflow.

[0023] In this embodiment, a protective shell 1 is sleeved outside the exhaust box 2 and the exhaust device 3, so as to provide protection, connect the exhaust box 2 and the exhaust device 3, and increase the aesthetics.

[0024] In this embodiment, the exhaust device 3 includes an exhaust fan 31, a motor 32 and a mounting bracket 33. The exhaust fan 31 is fixedly installed on the inner wall of the protective shell 1, and the exhaust fan 31 is located between the motor 32 and the exhaust box 2. The motor 32 is fixedly installed on one side of the surface of the mounting bracket 33, and the mounting bracket 33 is used to support the motor 32. The output end of the motor 32 is connected to the exhaust fan 31, and the exhaust fan 31 is driven to rotate by the motor 32. The top and bottom of the mounting bracket 33 are connected to the inner wall of the protective shell 1.

[0025] In this embodiment, the baffle plates 23 are all designed in a Z-shaped structure, and the arrangement of this structure enables the baffle plates 23 to have the conditions for turning over.

[0026] Working principle:

[0027] During specific use, the motor 32 drives the exhaust fan 31 to rotate, and the exhaust fan 31 rotates to blow air toward the exhaust box 2, causing the baffle plate 23 to rotate outward. At the same time, the faster the exhaust fan 31 rotates, the stronger the wind force, and the larger the opening area of ​​the rain shield 23 to rotate outward. Similarly, the slower the exhaust fan 31 rotates, the stronger the wind force, and the smaller the opening area of ​​the rain shield 23 to rotate outward.

[0028] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
