[0002] The motor main shaft drives the fan blade at the air inlet to rotate to achieve air intake at the air inlet. The existing motor main shaft has a flat head at the end of the air inlet.

[0003] Chinese Patent CN220673525U discloses a motor, which includes a motor body. The motor body includes a stationary component and a rotating component. The stationary component includes a housing, and the housing includes a housing body, a front end cover provided at the front end of the housing, and a rear end cover provided at the rear end of the housing. The rotating component includes a rotating shaft, a first bearing and a second bearing. The front end of the rotating component is positioned on the front end cover through the first bearing, and the rear end is positioned on the rear end cover through the second bearing. The position centers of the first bearing and the second bearing coincide with the mass center of the motor.

[0004] However, the existing device still has the following problems: the flat head is adopted at the shaft end, which is easy to generate eddy currents during air intake, affecting the air intake efficiency; when used in extreme weather such as rainy days, the existing device uses a top cover to block rain, but this method is easy to reduce the air intake efficiency, and at the same time, the waterproof effect is poor when the motor is tilted or the rain angle is inclined, resulting in ineffective protection of the motor.

[0005] Based on this, the utility model designs a motor that improves performance through a shaft to solve the above problems. Summary of the Utility Model

[0006] In view of the above-mentioned drawbacks of the prior art, the utility model provides a motor that improves performance through a shaft.

[0007] To achieve the above object, the utility model is realized through the following technical solutions:

[0008] A motor that improves performance through a shaft includes a motor base and a motor housing. The motor housing is fixedly installed outside the motor base through a support cross bar. An air inlet is provided at the top of the motor housing. A bullet-shaped shaft is rotatably installed on the motor base, and the end of the bullet-shaped shaft is located at the center of the circle of the air inlet. An impeller is fixedly installed on the upper part of the bullet-shaped shaft.

[0009] Furthermore, the end of the bullet-shaped shaft is set in a bullet shape;

[0010] An air inlet chamber is arranged inside the motor housing;

[0011] A waterproof component is arranged on the inner wall of the motor housing.

[0012] Further, the waterproof component includes a waterproof outer ring and a waterproof inner ring. The waterproof outer ring is fixedly installed on the inner wall of the motor housing, and the waterproof inner ring is fixedly installed on the outer wall of the motor base;

[0013] A ring plate is fixedly connected to the inner side wall of the waterproof outer ring, and an outer ring groove is formed at the top of the ring plate.

[0014] Further, an inner ring plate is fixedly connected to the outer wall of the waterproof inner ring, and an inner ring groove is formed at the bottom of the inner ring plate.

[0015] Further, the outer end of the inner ring plate extends to the inner side of the outer ring groove, and the outer end of the outer ring plate extends to the inner side of the inner ring groove.

[0016] Further, a plurality of water outlets are evenly formed in the circumferential direction on the outer wall of the waterproof outer ring.

[0017] Further, a sealing component for sealing is arranged outside the water outlet.

[0018] Further, the sealing component includes a baffle and a bolt. The baffle is connected to the water outlet in a limit sliding manner, and the baffle is detachably and fixedly connected to the waterproof outer ring through the bolt.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. Driving the bullet-shaped shaft to rotate, the bullet-shaped shaft drives the impeller to rotate for air intake operation. Since the top of the bullet-shaped shaft is bullet-shaped, the bullet-shaped shaft can reduce the inlet air resistance during rotation, allowing the air flow to enter the impeller flow channel more smoothly, improving the motor performance; facilitating installation and avoiding the concentricity problem caused by the collision between the shaft and the dynamic impeller shaft hole during the installation process; reducing the eddy current at the inlet and lowering the inlet noise.

[0021] 2. The water accumulated in the outer ring groove can flow out through the water outlet, thereby leading out most of the water and achieving a good waterproof effect.

[0022] 3. When drainage is required, the baffle is opened to increase the drainage volume. Different numbers of baffles can also be opened according to the water volume to make the water flow at the baffle and the air flow in a balanced state, reducing the escape of the air flow.

An impeller 6 is fixedly installed on the upper part of the bullet-shaped shaft 4.

[0035] When the utility model is in use, by driving the bullet-shaped shaft 4 to rotate, the bullet-shaped shaft 4 drives the impeller 6 to rotate for air intake operation. Since the top of the bullet-shaped shaft 4 is set to a bullet shape, the bullet-shaped shaft 4 can reduce the inlet air resistance during rotation, allowing the air flow to enter the impeller 6 flow channel more smoothly, improving the motor performance; facilitating installation and avoiding concentricity problems caused by the collision between the shaft and the dynamic impeller shaft hole during the installation process; reducing the eddy current at the inlet and reducing the inlet noise.

[0036] The end of the bullet-shaped shaft 4 is set to a bullet shape;

[0037] The end of the bullet-shaped shaft 4 can also be set to a conical shape;

[0045] When the air flow enters from the air inlet 3 and reaches the outer ring groove 712 through the air intake chamber 5, due to the air flow characteristics, the air flow will continue to move along the inner ring groove 722 into the motor, while the water flow will remain in the outer ring groove 712, thus achieving the effect of separating the air flow from the water flow and realizing the waterproofing of the motor;

[0046] A plurality of water outlets 8 are evenly provided on the outer wall of the waterproof outer ring 71 in the circumferential direction;

[0047] The water flow accumulated in the outer ring groove 712 can flow out through the water outlets 8, thereby leading out most of the water and achieving a good waterproof effect;
