Problems solved by technology

[0003] The air intake components of the air filter are arranged in the above manner, since the intake components are not designed for drainage, in rainy days or when the car is washed, water droplets easily enter the intake components through the air intake grille and flow into the air filter, resulting in air Water accumulated in the filter cavity will affect the service life of the filter element in the air filter, and even affect the performance and reliability of the engine in severe cases

Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] like figure 1 , figure 2 As shown, an air intake structure of an automobile air filter has an air filter intake cavity 1, an air intake 2, an air outlet pipe 3, lugs 4, drain holes 6, a convex hull 1a, and an arc surface 1b. The air intake cavity 1 is fixed on the upper beam of the water tank of the automobile above the air intake grille of the automobile, the air intake cavity 1 is a hollow structure, and the square air intake 2 is arranged at the upper position in front of the intake cavity 1, The circular air outlet pipe 3 is arranged on one side of the rear part of the air intake cavity 1 . Both sides of the lower end of the air inlet 2 are provided with lugs 4, and the center of the lugs 4 is provided with an assembly hole 5. The air filter air intake structure and the water tank upper beam above the automobile air intake grille pass through the assembly ...

Abstract

The invention relates to an air inflow structure of an automobile air cleaner. The air inflow structure comprises an air cleaner air inflow cavity with a hollow structure, and an air inlet and an air outlet tube are arranged on the air inflow cavity. The air inflow structure is characterized in that water draining holes for draining water are formed at the lowest position in the air inflow cavity. The air inflow structure of the automobile air cleaner has the advantages that valid air inflow in the air cleaner does not reduce without changing the spatial arrangement structure of the air cleaner; without affecting the shape of the air inlet of the air cleaner , water drops are prevented from flowing into the air cleaner by optimizing the shape of the air inflow structure of the automobile air cleaner..

Description

technical field [0001] The invention relates to a component of an automobile air intake system, in particular to an air intake structure of an automobile air filter. Background technique [0002] The car air filter is an important part of the car air intake system. The car air filter is mainly used to filter the impurity particles in the air, reduce the wear of the cylinder, piston and piston ring and other parts, so as to prolong the service life of the engine and reduce the air intake of the engine. noise function. The air intake components of the air filter are generally arranged behind the headlights of the car or on the upper beam of the water tank above the air intake grille. The air filter currently on the market is to reduce the intake temperature of the air and increase the intake of fresh air. If the design conditions permit, the air intake component of the air filter is generally arranged on the upper beam of the water tank above the air intake grille. The air i...
