Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile air conditioner filter, especially to automobile air conditioner filter with hierarchical filtration. BACKGROUND

[0002] The automobile air conditioner filter is a vital component in the automobile air conditioning system, which is like a "mask" for the car. During the driving process, external air enters the air conditioning system, and the automobile air conditioner filter is used to purify these air. It can effectively intercept dust, pollen, mold, bacteria, harmful gases and other impurities in the air, ensuring that the air entering the vehicle is fresh and clean, creating a healthy and comfortable environment for the driver and passengers, and also helping to protect the internal components of the automobile air conditioning system and prolong its service life.

[0003] The automobile air conditioner filter is mainly composed of a filter layer, a frame and a sealing component. The filter layer is the core part of air purification, generally including primary, medium and high efficiency filter materials. The primary filter material can intercept large particle impurities, the medium filter material can filter smaller dust and pollen, and the high efficiency filter material can capture bacteria, viruses and other small pollutants. Some also add an activated carbon layer to adsorb harmful gases and odors. The frame is made of plastic or rubber material, which supports and fixes the filter layer to ensure the stability of the overall shape of the filter.

[0004] The traditional automobile air conditioner filter structure is relatively simple, and only a single filter layer is usually provided. This is mainly because the early air quality requirements in the vehicle were relatively low, and the production cost was reduced and the manufacturing process was simplified. This single filter layer can usually only filter larger particles, and cannot effectively remove small particles, harmful gases and odors in the air. Due to the lack of multi-stage filtration function, the air quality in the vehicle is difficult to be fully guaranteed, and the driver and passengers are easily affected by pollen, bacteria, harmful gases and other pollutants, affecting their health. Moreover, the single filter layer is easily clogged by various impurities after long-term use, which not only reduces the filtering effect, but also affects the air volume of the air conditioning system, increases the energy consumption of the air conditioning system, shortens the service life of the air conditioning system, and makes the user need to replace the filter and maintain the air conditioning system more frequently. SUMMARY

[0005] In order to make up for the above shortcomings, the utility model provides an automobile air conditioner filter with hierarchical filtration, which aims to improve the problem that the traditional automobile air conditioner filter structure is relatively simple, leading to the difficulty in fully guaranteeing the air quality in the vehicle, and the driver and passengers being easily affected by pollen, bacteria, harmful gases and other pollutants, affecting their health.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0019] Specifically, when the outside air enters the filter, the air first enters the inner space of the filter chassis 1, and in the inner space of the filter chassis 1, the coarse hole non-woven fabric 13 is fixed. The fiber gap of the coarse hole non-woven fabric 13 is relatively large, and its main function is to intercept large-volume impurities such as wind-entrained leaves, accidentally-entrained insects, and large-particle dust generated during road travel. After the air filtered by the coarse hole non-woven fabric 13, it will continue to flow upward under the action of air flow, so as to reach the electrostatic electret filter layer 10. The electrostatic electret filter layer 10 is treated by a special process to make it have static electricity. By using the principle of static adsorption, it can capture smaller particles in the air, such as bacteria, viruses and other small-diameter pollutants. Subsequently, the air filtered by the two stages is then passed through the activated carbon adsorption layer 11. The activated carbon adsorption layer 11 is composed of activated carbon with rich pore structure and has strong adsorption capacity, which can adsorb harmful components in automobile exhaust, formaldehyde and toluene and other common harmful gases in decoration, and other possible odors. Finally, the clean air purified layer by layer flows out from the top of the filter through the cover plate 12 and smoothly enters the automobile air conditioning system to create a fresh and healthy air environment in the car. When maintaining the filter, the filter chassis 1, the electrostatic electret filter layer 10 and the activated carbon adsorption layer 11 need to be disassembled. The connecting frame 4 is pulled by hand, the connecting frame 4 is fixedly connected with the bottom rotating column 3, the rotating column 3 is sleeved on the outer wall of the inner shaft 2, when the connecting frame 4 is stressed, the rotating column 3 will rotate on the outer wall of the inner shaft 2, so that the connecting frame 4 changes the inclination angle, the connecting frame 4 is provided with the clamping plate 5 on the top, with the change of the inclination angle of the connecting frame 4, the clamping plate 5 also moves to release the clamping state of the top filter layer, so that the filter layer can be easily taken out for replacement or cleaning. When the operation is completed, the connecting frame 4 is connected with the spring 9, and the spring 9 can push the connecting frame 4 to reset, so that the clamping plate 5 re-clamps and fixes the filter layer, so as to realize the quick disassembly and assembly of multiple filter layers, reduce the maintenance difficulty of the filter, make the filter replacement more timely, and help to maintain the good filtering performance of the filter, so as to ensure the cleanliness of the air in the car.

[0020] Working principle: when the outside air enters the filter, it first passes through the coarse hole non-woven fabric 13 fixed in the inner space of the filter chassis 1. The coarse hole non-woven fabric 13 can intercept large-volume impurities such as leaves, insects and large-particle dust. Then, the air filtered by the coarse hole non-woven fabric 13 continues to flow upward to the electrostatic electret filter layer 10. The electrostatic electret filter layer 10 captures smaller particles in the air by using the principle of static adsorption, such as bacteria, viruses and other small-diameter pollutants. Subsequently, the air passes through the activated carbon adsorption layer 11, which can adsorb automobile exhaust, formaldehyde, toluene and other harmful gases and odors. Finally, the clean air purified layer by layer flows out from the top through the cover plate 12 and enters the automobile air conditioning system to provide a fresh and healthy air environment in the car;

[0021] When it is necessary to disassemble and assemble the filter base 1, the electrostatic electret filter layer 10 and the activated carbon adsorption layer 11, the connecting frame 4 is pulled, and the connecting frame 4 drives the rotating column 3 at the bottom thereof to rotate on the outer wall of the inner shaft 2 after being stressed, so that the connecting frame 4 changes the inclination angle, at this time, the clamping plate 5 at the top of the connecting frame 4 moves and releases the clamping of the top filter layer, and meanwhile, the connecting frame 4 can be reset and fixed again by the elastic force of the spring 9 to realize the quick disassembly and assembly of the multiple filter layers, reduce the maintenance difficulty, make the filter layer replacement more timely, help to always maintain the good filtering performance of the filter, and ensure the cleanliness of the air in the vehicle.

[0022] It should be finally pointed out that: the above only describes the preferred embodiments of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
