Problems solved by technology

However, the existing filter element has a single-layer structure, which has insufficient adsorption capacity for fine particles in the air, resulting in the filtered air still containing fine particles, which cannot meet the air supply requirements of the engine

Embodiment Construction

[0016] Such as figure 1 As shown, the embodiment of the present invention proposes a double-layer air filter, including a casing and a filter element, the casing forms an inner cavity with a circular cross section, and the filter element divides the inner cavity into an air intake cavity 10 and a filter element. An air outlet chamber 20, an air inlet 11 is arranged in the air inlet chamber 10, an air outlet 21 is arranged in the air outlet chamber 20, and the air entering through the air inlet 11 is filtered and supplied to the engine from the air outlet 21.

[0017] Wherein, the filter element includes: a first filter element layer 30, located on the side of the filter element facing the air inlet 11, with a gap diameter of 0.05-0.1um; a second filter element layer 40, located on the side of the filter element facing the air outlet 21, for absorbing water material, such as activated carbon fiber, etc.; the first filter element layer 30 is installed in the inner cavity through...

Abstract

The invention discloses a double-layer air filter. The double-layer air filter comprises a shell and a filter element, wherein the shell is formed with an inner cavity having a circular section; the inner cavity is divided into an air inlet cavity and an air outlet cavity by the filter element; an air inlet is formed in the air inlet cavity; an air outlet is formed in the air outlet cavity; air entering by the air inlet is supplied to an engine from the air outlet after being filtered; the filter element comprises a first filter element layer positioned on one surface of the filter element towards the air inlet, and a second filter element layer positioned on one surface of the filter element towards the air outlet and manufactured by a water sucking material; the first filter element layer is mounted in the inner cavity through a rotating shaft, and can rotate by surrounding the rotating shaft; a nozzle is arranged in the air inlet cavity, is connected with the water pump, and is used for uniformly spraying water mist to the first filter element layer; and a drain tank is positioned on the inner cavity wall at the lower part of the first filter element layer, and is used for receiving and draining water flowing down from the first filter element layer. The double-layer air filter enables the concentration of particles contained in passing air to be reduced so as to satisfy the air supply requirements of the engine.

Description

technical field [0001] The invention relates to the technical field of air filters for vehicles, in particular to a double-layer air filter. Background technique [0002] In order for the engine to function properly, a large amount of pure air must be drawn in. If the substances harmful to the engine in the air (dust, colloid, aluminum oxide, iron oxide, etc.) are inhaled, the cylinder and piston components will increase the burden, causing abnormal wear, and even mixing with the engine oil, causing greater wear , resulting in deterioration of engine performance and shortened life. The role of the car air filter is to provide clean air for the engine to prevent the engine from inhaling air with impurity particles and causing wear and tear. [0003] The existing air filter is composed of a shell and a filter element. The filter element divides the inner space of the shell into an air inlet cavity and an air outlet cavity. The filtered air is supplied to the engine from the...
