Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a water cup structure of a filter. Background Art

[0002] Compressed air filters are widely used in industrial production, laboratory environments and home life. They can effectively remove dust, particulate matter and liquid impurities in the air to ensure that the air quality meets the standard. Compressed air filters usually include cyclone blades and filter elements. Compressed air enters the filter from the air source inlet and rotates strongly through the tangential notch of the cyclone blades. The liquid oil and water and solid impurities in the compressed air are centrifugal and thrown onto the side wall of the filter cup. Then they flow along the surface of the cup to the bottom of the cup. The compressed air is filtered by the filter element and discharged from the air source outlet. The main function of the air filter cup is to collect the water filtered by the filter element. However, if the water level in the cup is too high, overflow may occur. Secondly, when the air filter is working, the air pressure inside the cup will gradually increase. If the cup cannot withstand the high air pressure, the cup body may rupture. In this case, not only will the cup be damaged, but it may also cause safety hazards to the user. Therefore, it is necessary to improve it. Utility Model Content
