[0017] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0018] See Figures 1 - 4, A swinging wall fan, comprising a fixed base 10, a head assembly 20, a fan blade 30 and a protective grille 40. The fan blade 30 is disposed within the protective grille 40. The head assembly 20 includes a motor 200, and a motor shaft 240 of the motor 200 extends upward into the protective grille 40. The fan blade 30 is fixedly disposed on the motor shaft 240. The protective grille 40 is fixedly disposed on the head assembly 20. The motor 200 is fixedly connected to a swinging shaft 201, and the swinging shaft 201 is rotatably connected to the fixed base 10. A first housing 250 is disposed at the rear side of the motor 200, and a second housing 260 is disposed at the lower side of the motor 200. The first housing 250 and the second housing 260 communicate with each other. The front side of the second housing 260 is open. The fixed base 10 is rotatably connected to a connecting rod 60, and the connecting rod 60 passes through the second housing 260 and extends backward into the first housing 250. A swinging assembly 50 rotatably connected to the connecting rod 60 is disposed within the first housing 250.

[0019] By providing the first housing and the second housing in the present utility model, the connecting rod can be hidden inside the housing, and the connecting rod is not exposed, improving the aesthetic property of the product. Moreover, there is no gap in the head, avoiding the problem of potential safety hazards caused by objects or fingers reaching into the gap.

[0020] See Figure 4 , The swinging assembly 50 includes a swinging motor 510 fixedly disposed within the first housing 250. The swinging motor 510 is connected to an eccentric member 520, and the eccentric member 520 is rotatably connected to the connecting rod 60. During actual operation, the swinging motor 510 drives the eccentric member 520 to rotate, and the eccentric member 520 drives the connecting rod 60 to perform a circular motion around the swinging motor 410. Thus, under the action of the connecting rod 60, the head assembly 20 is driven to rotate relative to the fixed base 10 with the swinging shaft 201 as the rotation axis, thereby realizing swinging. The swinging motor 510 rotates in both forward and reverse directions to achieve reciprocating swinging.

[0021] See Figure 4 , The swinging assembly 50 further includes a fixed bracket 500, and the swinging motor 510 is fixedly disposed on the fixed bracket 500.

[0022] See Figure 2 , The motor 200 includes a motor housing 210, a stator assembly 220 is disposed within the motor housing 210, a rotor assembly 230 is rotatably disposed within the stator assembly 220, and the motor shaft 240 is connected to the rotor assembly 230.

[0023] See Figure 4, the front wall surface of the first housing 250 is attached to the rear wall surface of the motor housing 210. A first sealing ring 215 is provided between the front wall surface of the first housing 250 and the rear wall surface of the motor housing 210. The front wall surface of the first housing 250 is attached to the rear wall surface of the second housing 260. The setting of the first housing 250 not only hides the connecting rod 60, but also can increase the sealing performance of the motor 200. It can block water for the motor 200 to prevent water droplets from falling on the wire holes on the rear side wall surface of the motor 200. At the same time, adding the first sealing ring 215 can enhance the sealing performance between the first housing 250 and the motor housing 210.

[0024] See Figure 4 , the motor housing 210 includes a front housing 212 and a rear housing 211 that are connected to each other. A second sealing ring 213 is provided between the front housing 212 and the rear housing 211, which can enhance the sealing performance between the front housing 212 and the rear housing 211.

[0025] See Figure 4 , a third sealing ring 214 is provided on the front side wall surface of the motor housing 210. The third sealing ring 214 is sleeved on the motor shaft 240. It can enhance the sealing performance between the front housing 212 and the motor shaft 240.
