A limit rod (204) is slidably provided on the outer wall of the through plate (203). A push column (205) is fixedly installed on the side of the through plate (203) away from the spring (202). A filter plate (206) is provided on the side of the push column (205) away from the through plate (203).

3. An air filter assembly for an oil tank as defined in claim 2, wherein: The filter plate (206) is rotatably connected to a rotating column (207) on the side away from the push column (205). A scraper (208) is fixedly installed on the outer wall of the rotating column (207). A fan blade (209) is provided on the side of the scraper (208) away from the filter plate (206).

4. An air filter assembly for an oil tank as defined in claim 2, wherein: The outer wall of the filter plate (206) is fixedly installed with the inner wall of the air inlet pipe (103), the outer wall of the push column (205) is sleeved inside the filter plate (206), and the through plate (203) has an air vent.

5. An air filter assembly for an oil tank as defined in claim 3, wherein: The scraper (208) is slidably disposed on the side away from the fan blade (209) and on the side of the filter plate (206) away from the push column (205), and the scraper (208) is disposed on an inclined surface on the side away from the fan blade (209).

6. An air filter assembly for an oil tank as defined in claim 1, wherein: The disassembly and assembly unit (300) includes a connecting block (301) fixedly installed on the outer wall of the core tube (102). A clamping plate (302) is rotatably connected inside the connecting block (301). A first magnetic block (303) is fixedly installed on the side of the clamping plate (302) near the core tube (102). A second magnetic block (304) is fixedly installed on the side of the first magnetic block (303) away from the clamping plate (302). A clamping block (305) is fixedly installed on the outer wall of the air intake pipe (103). A positioning post (306) is fixedly installed at the end of the core tube (102).

7. An air filter assembly for an oil tank as defined in claim 6, wherein: A vertical plate (307) is provided on the side of the card block (305) away from the core tube (102). A slide rod (308) is slidably provided inside the vertical plate (307). A slip ring (309) is fixedly installed at the end of the slide rod (308).
