Description

Technical Field

[0001] The utility model relates to the field of air filters, in particular to an air filter with a honeycomb structure. Background Art

[0002] The working principle of a car air filter is mainly to filter impurities in the air through the filter element. Its working principle is as follows: Inertial separation: When air passes through the filter, larger impurity particles will be thrown to the edge of the filter due to inertia, thereby separating from the air; the filter element in the air filter is usually made of paper, cotton or fiber materials, which can block tiny particles in the air, such as dust, pollen, bacteria, etc., thereby achieving air filtration; the working principle of a car air filter is a complex process, involving multiple principles such as inertial separation, filtration and adsorption. Through the synergistic effect of these principles, the air filter can effectively filter impurities in the air, provide clean air for the engine, and ensure the normal operation of the engine;

[0003] The serrated filter media in a car's air filter are more likely to fit together when subjected to external forces. When the air filter is subjected to external pressure, such as extrusion caused by improper installation or vibration during vehicle driving, the serrated slopes will guide adjacent filter media parts to gradually approach each other, eventually squeezing them together. This makes it impossible for the filter media to evenly filter the dust-laden gas. Utility Model Content

[0004] The purpose of the present utility model is to provide an air filter with a honeycomb structure to solve the defect mentioned in the above background technology that the inclined surface of the sawtooth will lead the adjacent filter material parts to gradually approach each other, and eventually cause them to be squeezed together, making it impossible for the filter material to uniformly filter the dust-laden gas.

[0005] To achieve the above-mentioned purpose, an air filter with a honeycomb structure is provided, comprising a filter base, a filter outer frame fixedly mounted on the surface of the filter base, and the filter outer frame is adapted to the size of the air filter material, and the air filter material is fixed inside the filter outer frame by a card clip, and the filter outer frame is adapted to the size of the honeycomb sheet, and honeycomb holes are opened on the honeycomb sheet, and a card clip is fixed on the side wall of the honeycomb sheet, the filter base, the air filter material and the honeycomb sheet are combined together to form a filter body, and the filter body is installed inside the engine compartment.

[0006] Preferably, the inner two side walls of the filter outer frame are provided with card-mounting grooves, and card-mounting pieces are fixedly mounted on both ends of the honeycomb sheet, and the sizes of the card-mounting pieces and the card-mounting grooves are adapted to each other.

[0007] Preferably, the card-mounting piece is fixed inside the card-mounting groove, and the filter outer frame and the honeycomb piece are positioned and installed through the card-mounting piece and the card-mounting groove, and the honeycomb piece is a rectangular structure made of metal material.

[0008] Preferably, screw holes are provided on both sides of the end face of the card plate, and two groups of through holes are evenly provided inside the card slot. At the same time, the screw holes are adapted to the size of the fixing bolts, and the fixing bolts are screwed through the through holes on the card slot and fixed inside the screw holes on the card plate.

[0009] Preferably, a plurality of groups of honeycomb holes are evenly formed on the surface of the honeycomb sheet, and the honeycomb holes are arranged in a regular hexagonal shape, and the distance between two adjacent groups of honeycomb holes is consistent.

[0010] Preferably, positioning plates are fixed at the four corners of the air filter material, and four groups of screw holes are evenly opened at the bottom of the filter base. At the same time, anchor screws are installed on the positioning plates, and the anchor screws pass through the positioning plates and are screwed to the bottom of the filter base. The positioning plates are circular.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model has a honeycomb sheet installed within the filter frame. The honeycomb sheet is installed in the following manner: a snap-on sheet is provided on both sides of the honeycomb sheet. The honeycomb sheet is snapped into the snap-on slots provided on the inner wall of the filter frame through the snap-on sheets on both sides. The arrangement of the honeycomb sheet can perform preliminary filtration of dust-laden gas through the multiple groups of honeycomb holes on the honeycomb sheet before being filtered by the air filter material, thereby reducing the working pressure of the air filter material.

[0013] 2. The air filter material of the utility model is a detachable structure inside the filter frame. When the car is to be maintained, the device can be disassembled, the air filter material can be taken out from the inside of the filter frame, and replaced with a new one. As long as the honeycomb sheet and the filter frame are intact, the device can be used continuously, thereby improving the economic efficiency of the device during use.

[0014] 3. The utility model uses a large amount of airflow to impact the surface of the honeycomb sheet. A large number of honeycomb holes are arranged on the surface of the honeycomb sheet to guide the dust-laden gas. Since a large number of honeycomb holes are arranged relative to the air filter material, the dust-laden gas discharged from the large number of honeycomb holes evenly impacts the surface of the air filter material, so that the air filter material can evenly filter the dust-laden gas, thereby improving the filtering efficiency and effect of the dust-laden gas.
