Description

Cyclone air filter suitable for gasoline engine generator Technical Field The utility model relates to the technical field of air filters, in particular to a cyclone air filter suitable for a gasoline engine generator. Background Cyclone air filters are devices that separate particulate matter from air by rotating the air stream, and are widely used in gasoline generators, diesel generators, and other mechanical devices. The working principle and the structure make the device particularly suitable for being used in environments with more dust or severe environments. For the gasoline engine generator, the cyclone air filter can effectively prevent dust, sand particles and other impurities from entering the engine, so that the engine is protected from abrasion, the running efficiency of the engine is improved, and the service life of the engine is prolonged. The cyclone air filter suitable for the gasoline generator comprises a bottom shell, a top cover, a cyclone separation unit, a separation mounting plate and a filter element partition plate, wherein the bottom shell and the top cover are connected in a relatively buckled mode, the separation mounting plate is embedded between the bottom shell and the top cover and separates the inner space of the bottom shell and the top cover into an air inlet cavity and a filter cavity, the cyclone separation unit is arranged on the separation mounting plate, an air inlet of the cyclone separation unit is positioned in the air inlet cavity, an air outlet of the cyclone separation unit is communicated with the filter cavity, the cyclone separation unit comprises a cyclone pipe and a separation cup, the cyclone pipe is arranged at the cup opening of the separation cup, the cyclone pipe comprises an outer pipe and an inner pipe which are coaxially arranged, vortex fan blades are arranged between the outer pipe and the inner pipe, the outer pipe is connected with the separation cup in a closely matched mode, a dust discharging port is arranged on the side face of the bottom of the separation cup, an air filter (connected with a carburetor air inlet) is arranged at the lowest position of the bottom shell corresponding to the filter cavity, and the filter element partition plate is arranged above the air outlet, and a filter element is arranged above the filter element.
