Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Referring to fig. 1-5, the present invention provides a technical solution: a centrifugal fan capable of discharging air from two sides comprises a fan shell 1, an air inlet 2 is formed in the side wall of one side of the fan shell 1, air outside the fan shell 1 enters the inside of the fan shell 1 through the air inlet 2, air outlets 3 are formed in the outer surface of the fan shell 1, the number of the air outlets 3 is two, the two air outlets 3 are symmetrically formed in the outer surface of the fan shell 1, the two air outlets 3 enable the centrifugal fan to blow air from two sides simultaneously, a fixing block 4 is fixedly arranged on the side wall of one side, far away from the air inlet 2, of the fan shell 1, a motor 5 is arranged inside the fixing block 4, the fixing block 4 fixes the motor 5, a fixing frame 6 is connected to the side wall, far away from the fan shell 1, of the fixing block 4 in a sliding mode, the fixing frame 6 seals the motor 5, a fixing bolt 7 is rotatably connected to the side wall of one side, far away from the fixing frame 4, the fixing bolt 7 penetrates one side of the fixing frame 6 and extends to the other side of the fixing frame 6, fixing bolt 7 is fixed mount 6, and one side lateral wall of fixed block 4 is equipped with admittedly and connects electric block 8, and through connecing electric block 8 to energize motor 5, one side lateral wall of fixed block 4 is seted up flutedly 9, can be more convenient take up fixed block 4 through recess 9.

The material of fan shell 1 is the aluminum alloy, and fan shell 1 of aluminum alloy system has promoted centrifugal fan's pressure resistance, has promoted fan shell 1's corrosion resistance simultaneously.
