Description

Technical Field

[0001] The utility model belongs to the technical field related to air filter elements, and particularly relates to an air filter element assembly. Background Art

[0002] The air filter assembly is an important component in the intake system of a car engine. Its main function is to filter the air entering the engine, preventing dust, sand and other impurities in the air from entering the engine, and ensuring the normal operation of the engine. The air filter assembly usually consists of an air filter element and an air filter housing. The air filter element is the core component of filtering the air. Its material is mostly paper or synthetic fiber, which can filter out tiny particles and impurities in the air. The air filter housing is a component that protects the filter element and fixes the entire air filter assembly. It is usually made of plastic or metal, but it still has the following disadvantages in actual use:

[0003] The air filter assembly is directly installed when it is working. During the installation process, it is sealed only by a sealing ring. When sealing, the gap between the sealing ring and the installation structure is prone to cause air leakage, affecting the cleanliness inside the equipment;

[0004] When the air filter assembly is working, a large amount of dust will accumulate on the surface of the filter after filtration, and the dust needs to be discharged regularly. When the dust is discharged, all structures need to be disassembled to discharge the dust on the surface of the filter, which is not convenient. Utility Model Content

When working, the filter plate is fixed therein through the protective shell, the rotating handle is connected to it through the connecting plate, the inner sealing component is fixed therein through the fixing block, and the internal sealing of the connecting port of the exhaust equipment is performed through the cooperation of the inner sealing component.

[0008] Furthermore, a fixing port is provided in the top center of the protective shell, and the two filter plates are respectively arranged on both sides of the fixing port. Three equally spaced air inlets are vertically provided on both sides of the protective shell. The protective shell is fixed to the fixing frame through the fixing port, and the dust in the protective shell is discharged through the dust discharge port, and the filtered air is input into it through the air inlet.

[0009] Furthermore, a rotating sleeve is fixed to the side of the connecting plate away from the protective shell along the vertical center line, and a rotating handle is movably connected inside the rotating sleeve. The connecting plate drives the protective shell to move by pushing and pulling the rotating handle movably connected to the rotating sleeve.

[0010] Furthermore, a sealing frame is fixed to the top of the fixed block outside the movable opening, and a fixing frame is fixed to the bottom of the fixed block. The fixing frame is fixed in the fixed opening, and the movable opening is sealed after installation by the cooperation of the sealing frame.

[0011] Furthermore, an outer mounting frame is fixed to the upper portion of the outer side of the fixing block, and mounting holes are evenly opened in the outer mounting frame. The fixing block provides a movable connection function for mounting bolts through the mounting holes on the outer mounting frame.

[0012] Furthermore, the inner sealing assembly also includes a guide bar, a guide bar is fixed on the top of the inner fixed bar, the guide bar is fixed in the movable port, and the movable port for guiding external air extraction through the guide bar is movably connected to the flexible sealing strip.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the air filter element assembly is prone to air leakage and affects the cleanliness of the equipment when it is working by arranging a protective shell, a fixing block and an inner sealing component. The connecting port of the exhaust device is aligned with the movable port on the fixing block, the connecting port is inserted into the movable port, the mounting bolt is inserted from below the mounting hole, and then screwed into the mounting structure of the exhaust device. After the mounting bolt is tightened, the connecting port of the exhaust device is completely inserted into the movable port and enters the inner fixing strip under the guidance of the guide strip. With the cooperation of the flexible sealing strip in the inner fixing strip, the gap between the connecting port and the inner wall of the movable port is sealed. After the mounting structure and the sealing frame are pressed on the top of the fixing block, the gap between the connecting port and the fixing block is sealed, so that the gap between the connecting port and the fixing block is fully sealed, and the sealing of the gap between the air filter element assembly and the mounting structure is better guaranteed when it is working.

[0015] The utility model solves the problem that the air filter assembly is not convenient to discharge dust by arranging a protective shell and a connecting plate. When the connecting port on the exhaust device is installed in the movable port on the fixed block, air is immediately exhausted in the protective shell by the exhaust device. At this time, air enters the protective shell through the air inlet, and then passes through the filter plate to filter the plate. The air enters between the two filter plates. After working for a long time, the dust filtered out on the side of the two filter plates away from each other falls into the dust discharge port. By turning and pulling the rotating handle, the protective shell is drawn out from the installation position, and the dust is then output from the protective shell through the dust discharge port, making it more convenient for the air filter assembly to discharge dust.
