[0047] Figures 1 to 4 A wall fan provided for an embodiment of the present application, the wall fan includes a mounting base 1, a detection module, a left - right swing mechanism 4, and a fan body 5. The mounting base 1 is used for connecting to a wall; the detection module is arranged on the mounting base 1 and is used for detecting the user's position; the left - right swing mechanism 4 includes a left - right swing housing 41 and a left - right swing driving device 42 arranged inside the left - right swing housing 41; the output end of the left - right swing driving device 42 movably penetrates through the left - right swing housing 41 and extends out of the left - right swing housing 41 to be connected to the mounting base 1; wherein, the left - right swing driving device 42 is electrically connected to the detection module; the fan body 5 is connected to the left - right swing housing 41.

[0048] It can be understood that the mounting base 1 provides a connection and installation foundation. The detection module can be used to detect the user's position. The left - right swing driving device 42 starts corresponding actions according to the detection result of the detection module. Specifically, when the detection module detects that the user leaves the air supply range, the left - right swing driving device 42 shuts down; when the detection module detects that the user appears in the air supply range, the left - right swing driving device 42 starts; when the detection module detects that the user shifts within the air supply range, the left - right swing driving device 42 drives the fan body 5 to swing to adjust the air supply direction.

[0049] like Figure 1 As shown, in this embodiment, a circuit board 3 is also included. The circuit board 3 is arranged in the mounting seat 1. The circuit board 3 is electrically connected to the detection module through wires, and the left and right swing driving device 42 is electrically connected to the circuit board 3 through wires.

[0050] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the detection module is a camera module 2, which is arranged on the mounting seat 1; the left and right swing driving device 42 is electrically connected to the camera module 2. It can be understood that the camera module 2 can capture images to determine the position of the user within the air supply range.

[0051] In some other embodiments, the detection module may also be an infrared sensor, which detects the user's location.

[0052] like Figure 1 As shown, in the technical solution of this embodiment, the mounting base 1 includes a first connecting arm 11 and a second connecting arm 12, the first connecting arm 11 is provided with a mounting cavity 11a; the circuit board 3 is arranged in the mounting cavity 11a; the first connecting arm 11 has two first side surfaces and a second side surfaces arranged opposite to each other, the first side surface is used to connect to the wall; the second side surface is provided with a camera channel 11b, and the camera channel 11b is connected to the mounting cavity 11a; the camera module 2 is arranged in the camera channel 11b; the second connecting arm 12 is arranged on the second side surface and is arranged at an angle to the first connecting arm 11; the end of the second connecting arm 12 away from the first connecting arm 11 is connected to the output end of the left and right swing driving device 42.

[0053] It is understandable that the second connecting arm 12 is disposed on the second side of the first connecting arm 11, so as to provide more space for the movement of the fan body 5 and expand the air supply range, thereby preventing the fan body 5 from hitting the wall during rotation.

[0054] like Figure 1 As shown, in the technical solution of this embodiment, the first connecting arm 11 and the second connecting arm 12 are vertically arranged.

[0055] like Figure 1 As shown, in the technical solution of this embodiment, the camera channel 11b is arranged at a position of the second side away from the second connecting arm 12, and the fan body 5 is located on the side of the second connecting arm 12 away from the camera module 2. In this way, the fan body 5 can be prevented from interfering with the image shooting of the camera module 2.

[0056] like Figure 1 As shown, in the technical solution of this embodiment, the axial direction of the camera channel 11 b is set at an angle with the second side surface, so that the camera direction of the camera module 2 is inclined toward the direction away from the second connecting arm 12.

[0057] It can be understood that the wall fan is usually installed at a relatively high position, and the imaging direction of the imaging module 2 is inclined downward, which can improve the accuracy of obtaining the user's position.

[0058] As Figure 1 , Figure 3 and Figure 4 As shown in, in the technical solution of this embodiment, the left and right swing driving device 42 includes a fixed frame 421, a driving motor 422, and a driven gear 424. The fixed frame 421 is disposed in the left and right swing housing 41 and is connected to the left and right swing housing 41; the driving motor 422 is disposed in the left and right swing housing 41; the driving motor 422 is installed on the fixed frame 421; the output end of the driving motor 422 is connected with a driving gear 423; the driven gear 424 meshes with the driving gear 423; the driven gear 424 is provided with a connecting member 425; the connecting member 425 movably passes through the left and right swing housing 41 and is inserted into the connecting groove 12a of the second connecting arm 12, and the connecting member 425 is connected to the second connecting arm 12.

[0059] It can be understood that the driving motor 422 drives the driving gear 423 to rotate. The driving gear 423 meshes with the driven gear 424. Since the driven gear 424 is fixedly connected to the second connecting arm 12 through the connecting member 425, the driven gear 424 will not rotate by itself, but generates a reaction force on the driving gear 423. The driving gear 423 moves along the tooth groove of the driven gear 424 under the reaction force. The movement of the driving gear 423 drives the driving motor 422 and then drives the fixed frame 421 to rotate. The rotation of the fixed frame 421 drives the left and right swing housing 41 to swing, and then drives the fan body 5 to swing.

[0060] As Figure 1 As shown in, in the technical solution of this embodiment, the driven gear 424 is provided with an assembly hole 424a, and the assembly hole 424a penetrates through the driven gear 424 and the connecting member 425; the fixed frame 421 is provided with an assembly shaft 4211, and the assembly shaft 4211 rotatably passes through the assembly hole 424a. Through the cooperation of the assembly hole 424a and the assembly shaft 4211, the stability of the rotational connection relationship between the fixed frame 421 and the driven gear 424 is improved.

[0061] As Figure 1As shown, in the technical solution of this embodiment, a fan motor 6 is further provided inside the left and right swing housing 41. The output end of the fan motor 6 is connected to the fan body 5. The fixed frame 421 is provided with a first support plate 4212 and a second support plate 4213. The first support plate 4212 is connected to the left and right swing housing 41, and the fan motor 6 is installed on the second support plate 4213. The fan motor 6 that drives the blades inside the fan body 5 to rotate for air supply is installed inside the left and right eye swing housing. The second support plate 4213 provides a support basis for the installation of the fan motor 6. Since the fan body 5 and the left and right swing housing 41 swing together, the second support plate 4213 is connected to the fixed frame 421, which can ensure the synchronization of the fan motor 6 and the fan body 5 during swinging.

[0062] As Figure 1 As shown, in the technical solution of this embodiment, the left and right swing housing 41 includes a housing body 411 and an inner bracket 412. The housing body 411 has an accommodation cavity 411a. The left and right swing driving device 42 and the fan motor 6 are arranged inside the accommodation cavity 411a. The housing body 411 is connected to the fan body 5. The inner bracket 412 is arranged inside the accommodation cavity 411a and is connected to the housing body 411. The inner bracket 412 is connected to the first support plate 4212.

[0063] It can be understood that the connection between the left and right swing housing 41 and the fixed frame 421 is realized through the inner bracket 412, which is convenient for assembly. The housing body 411 is connected to the fan body 5 to achieve the purpose of synchronous swinging of the left and right swing housing 41 and the fan body 5.

[0064] As Figure 1 As shown, in the technical solution of this embodiment, a vertically swingable member 121 is rotatably connected to the end of the second connecting arm 12 away from the first connecting arm 11. The vertically swingable member 121 is provided with a connecting groove 12a, and the connecting member 425 is connected to the vertically swingable member 121.

[0065] It can be understood that the vertically swingable member 121 can be used to adjust the angle of the fan body 5 in the vertical direction. In this embodiment, the vertically swingable member 121 is adjusted manually by the user, and this method adopts the structure for manually adjusting the fan body 5 in the vertical direction in the prior art, so it will not be elaborated here.
