Description

Technical Field

[0001] The utility model relates to the field of filters, and more specifically, to a filter for automobiles. Background Art

[0002] Filter refers to an accessory that filters impurities or gases through filter paper. It generally refers to automobile filters, which are engine accessories. According to different filtering functions, they are divided into: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, air conditioning filter, etc. The engine has three filters: air, oil, and fuel, which are generally called "three filters". Together with the air conditioning filter, it is commonly known as four filters. They are responsible for filtering the lubrication system, the medium in the combustion system, the engine intake system, and the cabin air circulation system.

[0003] For example, a car filter disclosed in announcement No. CN112112747A relates to the technical field of automobile accessories, and includes a filter frame, the upper surface of the filter frame is fixedly connected to an air intake plate mechanism by screws, side plates are fixedly connected to both sides of the lower surface of the filter element housing, and the two side plates are respectively fixedly connected to the opposite inner sides of the filter element housing by screws, and the inner side of the filter element housing is fixedly connected to a plurality of equally distributed slot plates, and a first filter screen is inserted into the plurality of slot plates from the upper part of the filter element housing, and a second filter screen is inserted into the plurality of slot plates from the lower part of the filter element housing, and the first filter screen and the second filter screen are staggered and bite, and the first filter screen and the second filter screen are fixedly connected to the slot plates, and a dust sticking mechanism is fixedly connected to the lower surface of the filter frame by screws. In the present invention, the first filter screen and the second filter screen form a double-layer filtration, and the filtration effect is better, which can effectively reduce the dust entering the engine.

[0004] It can be seen from the above-mentioned public scheme that currently when gasoline flows into the interior of the filter, it will suddenly fall into the interior of the filter. Long-term use can easily cause the location where the gasoline falls to be damaged by the impact, thereby easily damaging the filter and reducing the service life of the filter. At the same time, the filter mesh arranged inside the filter is made of filter paper. After long-term use, the filter paper is easily corroded and damaged due to the immersion of gasoline, thereby breaking and becoming unusable. Utility Model Content
