[0003] At present, in the operation process of existing fans, various components of the fan are mostly connected together by bolts or welding methods. Its own noise reduction effect is not good. The fan is prone to generate large noise due to running vibration, which affects normal production and is difficult to meet the low-noise requirements of customers. Content of the Utility Model

[0006] Further, the inner moving housing is suspended inside the outer fixed housing, the inner moving housing and the outer fixed housing do not contact each other, and the distance between the inner moving housing and the outer fixed housing is centimeters.

[0008] Further, the two inner magnetic rings are symmetrically located outside the inner moving housing in the up-and-down direction. The two inner magnetic rings are respectively close to the two outer magnetic rings. The distance between the outer magnetic ring and the inner magnetic ring is [X] centimeters. By using the magnetic repulsion force between the large magnetic ring and the small magnetic ring, an inward thrust is applied to the inner moving housing, reducing the horizontal movement amplitude of the inner moving housing. And through the magnetic repulsion force between the outer magnetic ring and the inner magnetic ring, an up-and-down thrust is applied to the inner moving housing, making the inner moving housing located in the middle part of the outer fixed housing and reducing the up-and-down movement amplitude of the inner moving housing.

[0011] Further, there are two impellers. The two impellers are connected to the upper and lower ends of the driving shaft of the motor. Heat dissipation strips are arranged in a surrounding shape outside the motor. The heat dissipation strips are wavy.

By designing the heat dissipation strips to be wavy, the heat dissipation area of the motor itself is effectively increased.

[0012] The utility model provides a low-noise magnetic levitation fan, which has the following beneficial effects:

[0013] When the utility model is in use, by using the magnetic repulsion force between the large magnetic ring and the small magnetic ring, an inward thrust is applied to the inner moving housing, reducing the horizontal movement amplitude of the inner moving housing. And through the magnetic repulsion force between the outer magnetic ring and the inner magnetic ring, an up-and-down thrust is applied to the inner moving housing, making the inner moving housing located in the middle part of the outer fixed housing and reducing the up-and-down movement amplitude of the inner moving housing. It plays a shock-absorbing effect during the operation of the fan, effectively reducing the noise generated by the fan due to vibration and ensuring the silent operation effect of the fan.

[0014] In addition, by designing the inner magnetic ring and the outer magnetic ring to be wavy, the convex part of the inner magnetic ring can receive the opposite magnetic repulsion force from the concave part of the outer magnetic ring, and the convex part of the outer magnetic ring can receive the opposite magnetic repulsion force from the concave part of the inner magnetic ring, preventing the inner moving housing from rotating and ensuring the stability of the state of the inner moving housing.

[0015] In addition, the motor drives the two impellers to rotate synchronously, effectively improving the wind power. By designing the heat dissipation strips to be wavy, the heat dissipation area of the motor itself is effectively increased. The air flows in the curved channels between the heat dissipation strips, taking away the heat generated by the motor and ensuring the low-temperature operation effect of the motor.
