Problems solved by technology

[0003] Fans are used in harsh environments, such as outdoors, high temperature, or other environments where water or dust may intrude, and they need to be cleaned and rinsed frequently. Commonly used fans generally have ventilation holes in the casing to ensure heat dissipation. When flushing, a large amount of water will directly enter the fan casing and rush into the motor, which is easy to cause damage to the motor. However, the current underwater waterproof motor on the market is too expensive, and this type of waterproof motor lacks heat dissipation and ventilation devices. It is not suitable for daily high-temperature kitchens or factories, so a new type of fan motor that can maintain the heat dissipation effect of the motor and be waterproof is needed

Embodiment Construction

[0020] Such as figure 1 , figure 2 As shown, the present invention provides a waterproof fan motor, which includes a housing 11, a front end cover 12, a rear end cover 13 and a motor shaft 14, and also includes a motor ear 18 affixed to the bottom of the housing; The rear end cover is respectively located on the front end surface and the rear end surface of the housing, and the motor shaft passes through the front end cover and is connected with the rotor inside the housing; the front end cover and the rear end cover are respectively provided with drainage components 15 .

[0021] Specifically, the drainage component 15 is installed horizontally on the side walls of the front end cover 12 and the rear end cover 13 . When flushing, water will not flow into the motor due to gravity, which effectively prevents a large amount of water from flowing in.

[0022] Specifically, the front end cover 12 and the rear end cover 13 respectively have two drainage parts 15 arranged symmetr...

Abstract

The invention discloses a waterproof fan motor which comprises a shell, a front end cover, a back end cover and a motor shaft. The front end cover and the back end cover are at the front end face and the back end face of the shell. The motor shaft goes through the front end cover and is connected to the rotor in the shell. The front end cover and the back end cover are provided with water drainage components. Compared with the prior art, the waterproof fan motor has the advantages that through arranging the water drainage components at the front end cover and the back end cover, and the damage of the motor by the residual water in the motor shell can be avoided. In addition, the components in the waterproof fan motor are subjected to waterproofing treatment, external moisture enters into the motor shell through the water drainage components and then is discharged through the water drainage components, a part of heat also is brought away, and an effect of cooling is achieved.

Description

technical field [0001] The invention relates to the technical field of electric fan products, in particular to a waterproof fan motor. Background technique [0002] An electric fan is a household appliance that uses a motor to drive the fan blades to rotate to accelerate the air circulation. It is mainly used to cool and relieve heat and circulate air. It is widely used in homes, offices, shops, hospitals, hotels and other places. The electric fan is mainly composed of fan head, fan blade, net cover, support frame and control unit and other components. [0003] Fans are used in harsh environments, such as outdoors, high temperature, or other environments where water or dust may intrude, and they need to be cleaned and rinsed frequently. Commonly used fans generally have vent holes in the housing to ensure heat dissipation. When washing, a large amount of water will directly enter the fan casing and rush into the motor, which is easy to cause damage to the motor. However, th...
