Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] Such as Figure 1-Figure 4 The intake structure of an air filter shown includes an intake box 2 and an intake pipe 3 connected to the intake box 2, and the intake pipe 3 communicates with the intake box 2; the rear side wall of the intake box 2 There is an air outlet 7 for directly communicating with the air intake cavity of the air filter, and one or more deflectors 6 extending vertically in the air intake box 2 are provided, and the deflectors 6 are vertically extended along the vertical direction. The deflector 6 is located at the front side of the air outlet 7, and there is a gap between the deflector 6 and the front side wall of the air intake box 2, and the deflector 6 is inclined to the left or right from the back to the front; A water outlet 10 is provided on the lower side wall 8 of the gas box 2 .

[0024] With the above-mentioned structure, the air enter...

Abstract

The invention relates to an air inlet structure of an air filter. The air inlet structure comprises an air inlet box and an air inlet pipe which is connected with the air inlet box. The rear side wallof the air inlet box is provided with an air outlet which directly communicates with an air inlet cavity of the air filter. The air inlet box is internally provided with one or more guide plates which extend up and down. The guide plates are located on the front side of the air outlet. A gap is reserved between the guide plates and the front side wall of the air inlet box. The guide plates incline leftwards or rightwards from back to front. The lower side wall of the air inlet box is provided with a water draining opening. By means of the air inlet structure, rain and snow which enter the airfilter can be reduced, and meanwhile, the air inlet uniformity of the air filter can be improved.

Description

technical field [0001] The invention relates to a vehicle air filter, in particular to an air intake structure of the air filter. Background technique [0002] The air filter is an important component of the engine intake system, which is used to filter dust and provide dry and clean air to the engine. The existing air filter has the following problems: the air directly enters the air filter through the intake pipe of the air filter, and there are problems of poor air intake uniformity and poor dust removal effect; in rainy and snowy weather, rain and snow are easy to Entering the air filter through the intake pipe of the air filter will seriously affect the service life of the filter element of the air filter. Intake resistance of the air filter. Contents of the invention [0003] The purpose of the present invention is to provide an air intake structure of the air filter, which can reduce the entry of rain and snow into the interior of the air filter, and at the same t...
