Abstract

The invention relates to the technical field of vehicle equipment and discloses a multifunctional air filter. The multifunctional air filter comprises a filter body, and a pull rod connected with the filter body is arranged at the upper end of the filter body. A vertical unloading flow channel is formed in the pull rod, and a transverse unloading flow channel communicating with the vertical unloading flow channel is formed in the upper end of the filter body. A sealing sleeve sleeved on the pull rod is arranged at the lower end of the pull rod, and the sealing sleeve is arranged between the filter body and the pull rod. A sealing lip is arranged at the lower end of the sealing sleeve, and an electromagnetic sealing device matched with the sealing lip for sealing is arranged in the filter body. A detection flow channel communicating with the transverse unloading flow channel and a pressure sensor used for monitoring air pressure in the detection flow channel are arranged on the filter body, and a control panel connected with the pressure sensor and the electromagnetic sealing device is arranged on the filter body. The multifunctional air filter adopts the control panel and the pressure sensor to control automatic unloading, thereby ensuring no-load starting of an air compressor and prolonging the service life of an assembly. Moreover, the multifunctional air filter blows back a filter element actively, thereby improving the air intake efficiency and the cleanliness of intake air.

Description

technical field [0001] The present invention relates to the technical field of vehicle equipment, in particular to a multifunctional air filter. Background technique [0002] The air compressor is the only energy-consuming equipment on the vehicle after the engine (diesel locomotive) or main drive motor (new energy vehicle) and air conditioner. , so its reliability, service life and maintenance cycle will greatly affect the safety of the vehicle and the cost of the user. [0003] The existing air compressors for vehicles are all positive displacement compressors. By inhaling air into the compression chamber, the volume of the compression chamber is dynamically changed by moving parts such as pistons, blades, and screws. Compress the air under normal pressure to the high pressure gas of the required pressure state. [0004] Since the moving room, the seal and the inner wall of the cavity will be in contact with the gas during air compression, the cleanliness of the inhaled ...
