Separated potting waterproof fan

Abstract

The invention relates to the technical field of fans, in particular to a separated type potting waterproof fan. Comprising a fan body and a control box, the fan body comprises a fan frame, a stator assembly and a fan assembly, a potting body is arranged in the center of the fan frame, and the fan assembly is rotationally connected with the potting body; the lower inner cavity of the potting body is an assembling cavity, and the upper inner cavity of the potting body is a filling cavity; the stator assembly is arranged in the assembling cavity in a penetrating mode and connected with the filling and sealing body in a matched mode, and the filling cavity is filled with sealing filler. A PCB (Printed Circuit Board) is arranged in the control box; a circuit on the stator assembly penetrates through the filling cavity so as to be electrically connected with the PCB; the waterproof fan is reasonable in structure, compliance detection is carried out after the fan assembly, the fan frame and the stator assembly are assembled, the sealing filler is injected into the filling cavity, the stator assembly is packaged in the potting body, electronic elements which are not resistant to low temperature are integrated in the control box, the waterproof fan can work in severe environments such as high temperature, low temperature and dust, and the service life of the waterproof fan is prolonged.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a separate potting and sealing waterproof fan. Background technique [0002] The fan motor is a general-purpose device that is used in various fields. As an electrical device, the fan motor is used in some harsh environments, such as outdoors, in places with more dust, in places with high humidity, and in salt spray areas such as seaside. The operational safety of the fan motor has a greater impact. In order to improve the stability and service life of the fan motor, it is usually necessary to pay attention to moisture-proof, waterproof and anti-static in the use environment requirements of the fan motor. Therefore, in the design and manufacturing process of the fan motor, its dustproof, waterproof and anti-static performance are relatively important. Most of the existing three-proof technology of fan motors are processed by coating, gluing and bakelite curing. Because the coating...

AI Technical Summary

Problems solved by technology

Because the coating process will destroy its integrity in the secondary processing and lose its protective effect, and the glue is liquid, it is not easy to repeat production and manufacturing, and it is difficult to make products with high consistency

The high-pressure injection molding machine (BMC injection molding machine) is different. The high-pressure injection molding machine can also completely achieve the desired shape, but the working temperature of high-pressure injection molding is too high (110-130 ° C) will cause damage to the object to be filled, and the generated high pressure will also cause damage. easy to damage electronic parts
