[0023] For example, during operation, the humidity sensor 403 detects the humidity inside the blower body 2. The lifting instrument 404 on the humidity sensor 403 is inverted, so that the higher the humidity, the more the pointer moves downward. When the pointer comes into contact with the micro switch 406, the controller 405 first introduces current into the electromagnet 407, and then controls the micro exhaust fan 409 to start running to extract air. The electromagnet 407 generates suction on the sealing block 203, causing the sealing block 203 to move downward. The piston chamber 202 is connected to the interior of the blower body 2. The oil, gas and moisture mixed gas inside the blower body 2 is drawn into the piston chamber 202, and then drawn into the pipeline 408 by the piston chamber 202. Thereafter, it will pass through the degreasing bottle 702 for degreasing, and then pass through the quick plug connector 706 for dehumidification, and finally be discharged from the outlet pipe 411. After a long period of use, the staff can directly take out the entire filter structure and replace the internal quick plug connector 706 and the degreasing bottle 702.
