Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1:

referring to fig. 1-8, the present invention provides a technical solution: a centrifugal fan for a dust remover comprises a base 101, wherein a suction mechanism 115 and a filtering mechanism 116 are arranged in the base 101, the suction mechanism 115 can start the fan, the filtering mechanism 116 can remove dust and collect garbage, prevent the garbage from being involved and adjust the height of the centrifugal fan.

The suction mechanism 115 comprises a sliding block 111 slidably connected with the base 101, the sliding block 111 is fixedly connected with a lifting pipe 102, the lifting pipe 102 is fixedly connected with a connecting pipe 103, the connecting pipe 103 is fixedly connected with a left fan shell and a right fan shell 104, the fan shells 104 are fixedly connected with a centrifugal fan 112, and the fan shells 104 are fixedly connected with a filter screen 108.

Referring to fig. 1-8, embodiment 2 is different from embodiment 1 in that:

the filtering mechanism 116 comprises a motor 113 fixedly connected with the base 101, the motor 113 is in power connection with a threaded shaft 114, the threaded shaft 114 is in threaded connection with the sliding block 111, and the connecting pipe 103 is fixedly connected with an elbow 105;

the return bend 105 fixedly connected with screwed pipe 107, screwed pipe 107 threaded connection has the replacement pipe 106, screwed pipe 107 with fixedly connected with drying screen 110 between the wet sponge 109, replacement pipe 106 fixedly connected with wet sponge 109.

The working principle is as follows:

placing the drying net 110 in the threaded pipe 107, and then fixing the replacement pipe 106 on the threaded pipe 107 after rotating the replacement pipe 106;

when the device is used, the motor 113 is started to drive the threaded shaft 114 to rotate, the sliding block 111 is driven to move upwards, the lifting pipe 102 is driven to move upwards, the connecting pipe 103 is driven to move upwards, the fan shell 104 is driven to move upwards, the threaded pipe 107 is driven to move upwards, the replacement pipe 106 is driven to move upwards, and the height of the outlet of the replacement pipe 106 is adjusted;
