Description
Technical Field
The utility model relates to a waterproof construction among the car air intake system especially relates to a waterproof type air cleaner.
Background
The automobile engine is provided with an air inlet filtering system which mainly filters impurities (dust, moisture and the like) in the air to prevent the impurities from entering the engine to influence the work of the engine and even damage the engine. The traditional seal between the upper shell and the lower shell of the air filter is mainly realized by supporting the upper shell of the air filter by the lower shell of the air filter. When water drops are gathered on the surface of the upper half shell of the air filter, the water drops can flow into the air filter through the edge of the lower half shell of the air filter for a long time, so that the filter element of the air filter is soaked, and the performance of the air filter and the work of an engine are influenced.
The prior art filter construction is shown in fig. 1 with the outer edge of the lower air filter housing 1 located at the outermost side of the overall air filter assembly. Under heavy rain or humid conditions, when water drops on the surface of the upper shell 3 of the air filter slide downwards, the water drops are collected in the groove of the lower shell 1 of the air filter; the long-term accumulation can cause the filter element 2 of the air filter to be soaked, and water enters the air filter to influence the performance of the engine.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to above technical problem, through revising air cleaner shell structure, will go up the outer fringe of casing and strengthen, widen and wrap up casing outer fringe under the air cleaner, reach and prevent that air cleaner shell surface drop of water from getting into the inside effect of air cleaner. The structure has the advantages of small surface area of the upper shell of the air filter, material saving and the like. The specific technical scheme is as follows:
the utility model provides a waterproof type air cleaner, it comprises lower casing, filter core and last casing: the filter element comprises a filter element body and a filter element supporting body, the filter element body is clamped on the filter element supporting body, and the outer edge of the filter element supporting body is provided with a convex part;
the lower shell is of a cavity structure, an air outlet is formed in the bottom of the lower shell, an outward flange part is arranged on the outer edge of an opening in the upper part of the lower shell, and the protruding part of the outer edge of the filter element support body is clamped at the flange part of the lower shell;
the upper shell is of a cavity structure, an air inlet is formed in the top of the upper shell, an outward surrounding edge is arranged on the outer edge of the lower opening and wraps the flange portion of the lower shell, a protruding baffle is arranged on the inner edge of the lower opening, and the baffle blocks the inner side of the protruding portion on the outer edge of the filter element support body.
Further, the lower shell is provided with a plurality of buckles, and the buckles are matched with the buckle grooves formed in the upper shell.
Furthermore, the flange part of the lower shell is attached to the surrounding edge, and the baffle plate of the upper shell is attached to the protruding part on the outer edge of the filter element support body.
The utility model discloses an air cleaner is the outward flange of casing down in the inboard of casing outward flange on the air cleaner. Under the condition that there is the drop on air cleaner upper housing surface, the drop can be along the surface downflow, and this structure does not have the recess, and the drop can not gather, can not soak air cleaner filter element, can keep the inside drying of air cleaner, and this structure has waterproof function. Through the structure of the utility model, reach and prevent that air cleaner surface drop of water from getting into its inside effect, also can reach the surface area that reduces air cleaner first casing simultaneously, save material, reduce cost's effect.
