Problems solved by technology

[0004] Since the fan 1 must be filled with a large amount of glue 11 as the protective case component, this process not only increases the production cost and consumes man-hours, but the glue used also has environmental pollution concerns.
In addition, since the colloid 11 completely seals and covers the circuit board 15, it will cause the circuit board 15 to be difficult to dissipate heat, which will cause the circuit board 15 to overheat and burn or greatly reduce the operating efficiency of the fan.
Furthermore, during the glue filling process, the electronic components on the circuit board 15 may also be damaged due to the temperature and internal stress during the solidification of the glue.
In addition, this method does not have a good waterproof effect on the outlet structure of the fan

Abstract

A fan comprises a bearing seat, a sealing part, a fan frame, a wire outlet structure, a motor and an impeller. The bearing seat is provided with a first wire outlet opening. The sealing part is provided with a first channel, wherein the first channel is arranged in the first wire outlet opening. The fan frame is provided with a groove and a second wire outlet opening, the sealing part is arranged in the groove, and the first channel is exposed out of the second wire outlet opening. The wire outlet structure is arranged on the second wire outlet opening and is provided with a second channel, and the second channel is mutually communicated with the first channel. The motor is arranged in the bearing seat. The impeller is connected with the motor and driven by the motor.

Description

technical field [0001] The invention relates to a fan, in particular to a waterproof structure of the fan. Background technique [0002] Due to climate factors, fans are prone to breakdown due to heat and humidity, so the waterproof structure of the fan is even more important, especially the outlet structure of the fan's wires, also known as the outlet structure, is even more important. If the sealing effect of the outlet structure is not good, it may cause water vapor to enter the inside of the fan and cause a short circuit, which in turn may cause the fan to burn out and shut down. [0003] Nowadays, most traditional fans use glue to fill the parts to be protected, so as to achieve waterproof function. Please refer to figure 1 , which is a sectional side view of an existing fan with waterproof function. The fan 1 includes a body 11 , a casing 12 , a plurality of fan blades 13 , a fan frame 14 , a circuit board 15 and a motor 16 . The glue 11 fills and covers the circuit...
