Novel air filter lower housing structure

Abstract

The invention discloses a novel air filter lower housing structure. The novel air filter lower housing structure includes a lower housing body, a filter element tray and a rotation disc mechanism; the filter element tray is fixedly arranged on the inner center of the lower housing body through a connection rod; the rotation disc mechanism includes an upper baffle plate with filtering holes, a lower baffle plate, a sealing film, and a fixing pin; the fixing pin is connected to the centers of the upper baffle plate and the lower baffle plate; the sealing film is arranged between the upper baffle plate and the lower baffle plate, and can vertically move along the fixing pin; a sealing film limiting ring is arranged on the fixing pin; a ball pin is arranged on the center of a bottom surface of the filter element tray; and the lower end of the ball pin is fixedly connected to the top end of the fixing pin. The novel air filter lower housing structure can improve the universality of air filters, and can lower the demand for the flatness of a ground surface in vehicle parking.

Description

technical field [0001] The invention relates to a lower casing of an air filter, in particular to a novel lower casing structure of the air filter. Background technique [0002] The automotive air filter assembly is used to filter the air and provide clean air. In any climate, the air filter needs to keep working continuously. The water vapor accumulated in the air during the intake process or the water droplets directly entering from the air intake in rainy days need to rely on the dust discharge holes on the lower housing of the air filter to be discharged. Therefore, when designing the air filter dust outlet, we usually design it at the lowest point of the air filter assembly on the vehicle. [0003] The structure of the air filter lower housing assembly in the prior art is as follows: figure 1 As shown, a similar structure is generally adopted in the industry, including a fixed shell body 100, a certain inclination angle is designed in the shape, a low point is artific...

Problems solved by technology

Corresponding to various layout positions, the probability that the lower shell assembly structure cannot be used at the same time is extremely high

[0005] The position of the dust discharge hole 200 is set based on the relatively horizontal state of the vehicle, but during the use of the vehicle, in some special environments (such as parking on a slope, etc.), the dust discharge hole 200 is no longer located at the bottom. The lowest point of the water level of the casing will cause the dust discharge hole 200 to fail to achieve the expected drainage function, resulting in rainwater being deposited in the casing body 100, and there is a hidden danger of wetting the air filter element
