A pump cavity 5 is provided in the pump body, and the pump body is connected to the motor 1 and the swinging member 2 is inserted into the pump cavity 5.
[0017] The working principle of the water pump noise reduction structure described in the utility model is achieved through the cooperation between the motor 1, the swing member 2, the elastic sleeve 3 and the pump body. Figures 1 to 3As shown, the swinging member 2 is made of plastic material, the mounting bearing 4 is made of metal material, and the output end of the motor 1 is sleeved with an elastic sleeve 3 between the mounting bearing 4 and the swinging member 2. The elastic sleeve 3 can avoid direct contact and friction between the swinging member 2 and the mounting bearing 4, and compared with the swinging member 2, the elastic sleeve 3 can undergo elastic deformation and reduce wear. The elastic sleeve 3 can be made of elastic materials such as rubber. The elastic sleeve 3 replaces the swinging member 2 and is connected to the mounting bearing 4 to reduce the wear of the swinging member 2. Compared with the traditional water pump, the noise reduction structure of the water pump can avoid the increase in the gap between the mounting bearing 4 and the swinging member 2, which increases the noise generated when the motor 1 is running.
[0018] Specifically, the swing member 2 is a hollow kit, the inner side of the swing member 2 is provided with a limiting groove 6 facing the mounting bearing 4, and the top and bottom surfaces of the swing member are provided with top columns 7, as shown in FIG. Figures 1 to 3 As shown, the elastic sleeve 3 is sleeved on the mounting bearing 4, and the sleeve is inserted into the limiting groove 6 of the swinging member 2 so that the swinging member 2 is sleeved on the elastic sleeve 3. The output end of the motor 1 drives the mounting bearing 4 and the elastic sleeve 3 to rotate, so that the swinging member 2 can swing back and forth within a set angle range, such as 60° to the left or right.

Subsequently, the fluid is delivered from the corresponding connected slots 16 of the two partitions 15 to one end of the delivery slots 14 corresponding to the two pump covers 9. Then, the fluid is delivered along one end of the delivery slot 14 to the other end of the delivery slot 14, and enters the pump chamber 5 from the delivery holes 17 corresponding to the two partitions 15. The output end of the motor 1 drives the swing member 2 to swing in the pump chamber 5, so that the fluid in the pump chamber 5 is delivered from the other delivery holes 17 of the two partitions 15 to the other delivery slot 14 of the pump cover 9. The fluid is delivered along the delivery slot 14 to the other slot 16 of the two partitions 15.
