[0039] Working principle: When air enters the air inlet pipe 210, the air pump 6 is started, and the input end of the air pump 6 draws air into the interior of the installation box 304 through the air extraction pipe 306, so that there is gas flow in the interior of the installation box 304, which in turn drives the impeller 305 to rotate, and then drives the rotating shaft 303 to rotate, so that the rotating shaft 303 can drive the rotating filter 302 to rotate, and after the rotating filter 302 rotates, the oil or impurities on the rotating filter 302 can be thrown off by centrifugal force, thereby extending the clogging time of the rotating filter 302, and at the same time, the thrust of the pushing spring 311 can be used to push the limit plate 312 and the connecting The connecting rod 313 exerts a force away from the pushing spring 311, thereby exerting a force on the scraper 309 to move away from the pushing spring 311, and then exerting a force on the top of the scraper 309 toward the pushing spring 311, thereby exerting an upward force on the scraper 309, thereby making the top of the scraper 309 close to the outside of the rotating filter 302, thereby facilitating the cleaning of the outside of the rotating filter 302, and allowing the scraper 309 to scrape off the oil and impurities on the outside of the rotating filter 302 that are not thrown off by the centrifugal force, and allowing the oil and impurities to fall into the inside of the collection box 307. At this time, the rotating door 314 can be opened to conveniently take out the oil and impurities inside the collection box 307.

[0040] After the oil in the air inlet pipe 10 enters the interior of the impurity collection tank 401, if the oil mist or impurities accumulate in the impurity collection tank 401, the electromagnetic pulse valve 404 is started, and the gas in the fixed pipe 403 enters the interior of the fixed cylinder 405 through the electromagnetic pulse valve 404, and then can push the limit ring 406 to move toward the drain pipe 409, so that the movable rod 407 can be pushed out of the interior of the fixed cylinder 405, and then the movable rod 407 can be used to push the movable plug 402 to move toward the drain pipe 409. When it moves to the limit plate 412, the movable plug 402 is used to push the limit plate 412 and the limit rod 411 to move toward the outside of the drain pipe 409, so that the plug head 410 can be driven to move toward the outside of the drain pipe 409. When the plug head 410 After completely moving out of the drain pipe 409, the movable plug 402 can be used to discharge the oil or impurities in the impurity collection tank 401. At this time, the exhaust function of the electromagnetic pulse valve 404 is turned on, and the air in the fixed cylinder 405 can be discharged. At this time, under the action of the tension spring 1 408, the movable rod 407 can be pulled in the direction of the electromagnetic pulse valve 404, and then the movable plug 402 can be driven to move in the direction of the electromagnetic pulse valve 404, so that the movable plug 402 can be reset. At this time, the oil or impurities in the air inlet pipe 2 10 can fall into the interior of the impurity collection tank 401. At the same time, the pull rope 413 can be pulled to reset, and then the plug 410 can be driven to reset, so that the plug 410 can be blocked in the drain pipe 409 again.

[0041] When replacing the rotating filter 302, first rotate the plug disc 508 upward, which can then drive the rotating column 506 to rotate, thereby compressing the torsion spring 507. When the plug disc 508 moves out of the interior of the locking ear 502, the elastic rubber ring inside the sealing cover 501 and the elastic action of the holding spring 510 can make the sealing cover 501 pop out a distance, and then the sealing cover 501 can be removed, and the rotating filter 302 can be taken out from the interior of the mounting shell 301. After the rotating filter 302 is placed in the interior of the mounting shell 301, the sealing cover 501 is placed in the mounting shell 301. 1, and press the blocking cover 501 towards the mounting housing 301 with force, thereby compressing the elastic rubber ring, and enabling the holding ring 512 and the limiting ring 511 to move towards the inside of the fixing ring 509, and compressing the holding spring 510. At this time, press the plug disc 508 downward, and use the action of the upper inclined surface of the plug disc 508 to squeeze the engaging ear 502, so that the blocking cover 501 is further moved towards the mounting housing 301, so that the inner side of the blocking cover 501 can be tightly attached to the side of the mounting housing 301 away from the mounting box 304, thereby completing the installation of the rotating filter 302;

[0042] When the air pressure inside the air storage box 7 is too high, the gas will push the sliding plate 804 to move toward the limit head 805. After the sliding plate 804 moves out of the air vent pipe 801, the gas inside the air storage box 7 can be discharged to the outside through the air vent pipe 801, thereby reducing the air pressure inside the air storage box 7. When the air pressure inside the air storage box 7 is reduced, the sliding plate 804 can be pulled toward the inside of the air vent pipe 801 under the tension of the second tension spring 806, so that the sliding plate 804 can be moved back into the inside of the air vent pipe 801 and the sliding plate 804 is used to block the inside of the air vent pipe 801, thereby preventing the gas inside the air storage box 7 from being discharged again.
