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 invention relates to the technical field of vehicle equipment, in particular to a multifunctional air filter. Background technique [0002] The air compressor is the energy-consuming equipment on the car after the engine (internal combustion locomotive) or the main drive motor (new energy vehicle) and air conditioner, because it is the only device that provides air source for the braking system, door opening and suspension systems , so its reliability, service life and maintenance period will greatly affect the safety of the vehicle and the user's expenditure cost. [0003] Existing vehicle air compressors are all volumetric compressors, by sucking air into the compression chamber, using moving parts such as pistons, vanes, and screws to dynamically change the volume of the compression chamber, with the help of the intake and exhaust check valves, to achieve A high-pressure gas that compresses air at normal pressure to the required pressure state....
