Under the elastic force of the second spring 24, the sliding rod 25 can drive the pressure frame 26 to move, so that the pressure frame 26 can press the four sides of the filter screen 62, so that the periphery of the filter screen 62 can be further sealed.

[0022] Working principle: When the staff uses this device to perform preliminary filtration on the outside air extracted by the fan body 1, the dust and debris in the outside air can be filtered under the action of the filter 62. When the filter 62 is used for a long time, the filter 62 may be blocked. Under the action of the first pressure sensor 19 and the second pressure sensor 20, the pressure on both sides of the filter 62 can be detected. When the pressure difference exceeds a certain range, the staff can use the PLC controller 7 to make the motor 65 start working, and then under the action of the motor 65, the placement roller 61 and the winding roller 64 can be rotated, so that the blocked filter 62 can be wound up by the winding roller 64, and the new filter 62 is moved to the specified position under the action of the placement roller 61, thereby improving the replacement efficiency of the filter 62.
