The fan is mounted on the fan cover by means of the mounting and positioning assembly, and the fan cover is detachably mounted on the fan bracket by means of the connecting assembly. When in use, the fan bracket is fixedly mounted on the air duct baffle, and then the fan is mounted on the fan cover by means of the mounting and positioning assembly, and then the fan cover is detachably connected to the fan bracket by means of the connecting assembly. When the fan needs to be replaced, it is only necessary to disassemble the fan cover and the fan bracket, and then the fan and the fan cover can be separated separately and the fan can be replaced, without the need to disassemble the air duct baffle and the fan bracket at the same time.

[0007] Preferably, the installation positioning assembly includes positioning plates and clips. Two sets of positioning plates and two sets of clips are provided on the fan cover. The two sets of positioning plates limit the fan, and the two sets of clips secure the fan. When in use, the fan is placed between the two sets of positioning plates and secured by the two sets of clips, thereby completing the assembly of the fan and the fan cover, which is simple and convenient.

[0008] Preferably, it further comprises pressing plates, and pressing plates are respectively provided at the four inner corners of the fan bracket; when the fan cover and the fan bracket are assembled, multiple groups of pressing plates cooperate with the fan cover to press and fix the fan, thereby improving firmness.

[0009] Preferably, the connecting component includes a claw, a bayonet, a threaded groove and a countersunk hole. The fan cover is provided with a claw and a countersunk hole, and the fan bracket is provided with a bayonet and a group of threaded grooves. The claw is clamped with the bayonet, and a No. 1 screw is passed through the countersunk hole, and the No. 1 screw is threadedly connected to the threaded groove; when the fan is installed on the fan cover and the fan cover is installed on the fan bracket, the claw is clamped with the bayonet and the threaded groove coincides with the countersunk hole, and then the No. 1 screw is passed through the countersunk hole and threadedly connected to the threaded groove to complete the connection.

[0010] Preferably, the number of the clamping claws is two groups, and the number of the clamping sockets is two groups; the fan cover and the fan bracket are clamped together by two groups of clamping claws and two groups of clamping sockets, thereby improving the firmness of the connection.

[0011] Preferably, the two groups of bayonet holes and one group of thread grooves are distributed in a triangle.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the fan bracket is fixedly installed on the air duct baffle, and then the fan is installed on the fan cover by installing the positioning assembly, and then the fan cover is detachably connected to the fan bracket through the connecting assembly. When the fan needs to be replaced, it is only necessary to disassemble the fan cover and the fan bracket, and then the fan and the fan cover can be separated separately and the fan can be replaced, without the need to disassemble the air duct baffle and the fan bracket at the same time.
