[0001] This utility model relates to the technical field of automotive air conditioning filters, and more specifically, to an automotive air conditioning filter that prevents dust from falling off. Background Technology

[0002] In recent years, as the automobile market has shown a gradual growth trend, consumers have also paid more and more attention to the performance of automobiles. Car air conditioning provides passengers with a comfortable riding environment, reduces travel fatigue, and creates good working conditions for drivers, playing an important role in ensuring drivers' safe driving.

[0003] A search revealed that publication number CN201082378Y discloses an automotive air conditioning filter, comprising a filter element and a housing formed along the side of the filter element. This automotive air conditioning filter is installed at the air intake of the car's air conditioning system, effectively intercepting dust and other air particles from entering the air conditioning system with the external air circulation, thus preventing particulate matter from entering the vehicle and ensuring the smooth operation of the air conditioning ventilation system. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] However, since most air conditioning filters are directly connected to the filter housing and are integrally formed, most air conditioning filters will have the following problems after long-term use: 1. Replacement requires complete disassembly; 2. The filter element is generally a single layer, so the filter element is less effective when in use.

[0005] Therefore, a car air conditioning filter to prevent dust from being shaken off is proposed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 5The automotive air conditioning filter shown includes a filter housing 1, with a filter element mechanism 2 disposed on the inner surface of the filter housing 1. The filter element mechanism 2 is the core part of the entire filter and consists of a multi-layer structure. Among them, the filter element plate 21 is the base layer, which is made of high-efficiency filter material. The upper surface has filter holes 22 arranged in a linear array. This linear array design can evenly distribute the airflow, ensuring that the air enters the filtration stage efficiently and stably. A partition 23 is fixedly connected to the upper surface of filter plate 21. The partition 23 not only provides support and separates filter plate 21 from the upper filter plate 24, but also guides airflow, allowing it to flow upwards more orderly. The filter mechanism 2 includes filter plate 21. Filter holes 22 are linearly arrayed on the upper surface of filter plate 21. A partition 23 is fixedly connected to the upper surface of filter plate 21, and filter plate 24 is positioned on the upper surface of partition 23. Filter plate 24 is located above partition 23 and also uses high-quality filter material. Its unique design allows it to work in tandem with filter plate 21 in terms of filtration effect. Filter holes 25 are linearly arrayed on the upper surface of filter plate 24. These filter holes are coordinated with filter holes 22 in terms of size, spacing, and other parameters, further improving filtration accuracy. Filter holes 25 are linearly arrayed on the upper surface of filter plate 24. A second filter plate 26 is fixedly connected to the upper surface of the filter element plate 24. A third filter plate 27 is set on the upper surface of the second filter plate 26. Filter holes 28 are arranged in a linear array on the upper surface of the filter element plate 27. The filter holes 28 are designed to take into full account the size distribution of dust particles and work together with the lower filter holes to achieve finer filtration. A third filter plate 29 is fixedly connected to the upper surface of the filter element plate 27. A fourth filter plate 210 is set on the upper surface of the second filter plate 26. Filter holes 211 are arranged in a linear array on the upper surface of the fourth filter plate 210. A fourth filter plate 212 is fixedly connected to the upper surface of the fourth filter plate 210. A sliding groove 213 is opened on the inner surface of the filter element housing 1. A filter element mechanism 2 is slidably connected to the inner surface of the sliding groove 213. The filter element mechanism 2 is arranged in a linear array inside the filter element housing 1. The sliding groove 213 adopts a high-precision machining process to ensure dimensional accuracy and surface flatness. Its function is to provide a smooth sliding track for the filter element mechanism 2, enabling easy installation and disassembly of the filter element mechanism 2, facilitating later maintenance and replacement. The filter element mechanism 2 is arranged in a linear array inside the filter element housing 1. This arrangement maximizes the use of the internal space of the filter element housing 1, achieving an orderly arrangement of multiple layers of filtration structure within a limited space. This significantly improves the overall ability of the automotive air conditioning filter to prevent dust from falling, providing a fresh and clean air environment inside the vehicle.

[0026] When the car's air conditioning is running, air enters the filter housing 1 and first comes into contact with the filter plate 21 in the filter mechanism 2. The air passes through the filter holes 22 arranged in a linear array on the upper surface of the filter plate 21. At this time, larger dust particles are intercepted on the filter plate 21. The air continues to flow upward and reaches the filter plate 24. Under the guidance of the partition 23, the air passes evenly through the filter holes 25 arranged in a linear array on the upper surface of the filter plate 24, further filtering out smaller dust particles. Then, the air comes to the filter plate 27. Similarly, under the action of the partition 26, the air passes through the filter holes 28 for further filtration, further intercepting even finer dust particles. Then, the air passes through the filter plate 210 and through the filter holes 211 for another filtration. Through layers of filtration, the air entering the car is cleaner, achieving the purpose of preventing dust from falling off.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0029] In a preferred embodiment, the inner surface of the slide 213 is provided with a groove 3, and the inner surface of the groove 3 is provided with a fixing mechanism 4. The fixing mechanism 4 includes a trapezoidal block 41, which is slidably connected to the inner surface of the groove 3. The trapezoidal block 41 is fixedly connected to one end of the spring 42, and the groove 3 is fixedly connected to the other end of the spring 42. The design of the groove 3 is ingenious, and its existence is not accidental, but to meet specific functional requirements. The fixing mechanism 4 provided on the inner surface of the groove 3 plays a crucial role in the operation of the entire device.

[0030] In a preferred embodiment, a pin 43 is passed through the upper surface of the filter housing 1 and is slidably connected to the pin 43. The pin 43 passes through the trapezoidal block 41 and is slidably connected to the trapezoidal block 41. Magnets are provided on the contact surfaces of the pin 43 and the trapezoidal block 41. This arrangement makes the pin 43 more stable in limiting the trapezoidal block 41, so that the trapezoidal block 41 will not shake during the driving process. At the same time, when multiple filter plates need to be disassembled, the pin 43 can be quickly disengaged from the trapezoidal block 41 by magnetic attraction, making disassembly and maintenance more convenient.

[0031] In a preferred embodiment, the upper surface of the filter housing 1 is provided with mounting holes 5.

[0032] The working process of this utility model is as follows: First, air enters the filter housing 1 and comes into contact with the filter mechanism 2. The filter mechanism 2 consists of multiple filter plates, from bottom to top: filter plate 1 21, filter plate 24, filter plate 3 27, and filter plate 4 210. Filter plate 1 21 has filter holes 22 arranged in a linear array on its upper surface. When air passes through filter holes 22, larger dust particles are intercepted. Partition 1 23 separates filter plate 21 from filter plate 24. After passing through partition 23, the air reaches filter plate 24. Filter plate 24 also has filter holes 25 arranged in a linear array on its upper surface, further filtering smaller dust particles in the air. The air passing through filter plate 24 then passes through partition 26 and reaches filter plate 3 27. The filter holes 28 on filter plate 327 filter the air again, intercepting finer dust particles. The air then passes through baffle 329 and reaches filter plate 410. The filter holes 211 on filter plate 410 perform a final round of fine filtration to ensure that the dust content of the air entering the car is as low as possible. The inner surface of filter housing 1 has a groove 213, and filter mechanism 2 can slide along the inner surface of the groove 213. This design facilitates the installation and removal of filter mechanism 2 and makes it convenient for daily inspection and cleaning of the filter. Alternatively, when it is necessary to fix the filter element mechanism 2, the filter element mechanism 2 is inserted into the trapezoidal block 41 through the sliding pin 43 that passes through the upper surface of the filter element housing 1. Due to the special shape of the trapezoidal block 41 and the elastic force of the spring 42, the trapezoidal block 41 will tightly press against the inner surface of the slide groove 213, thereby firmly fixing the filter element mechanism 2 in the filter element housing 1, preventing it from shifting due to vibration during vehicle operation, ensuring the stable operation of the filter element mechanism 2, and effectively preventing dust from falling off. The above is the working principle of the car air conditioning filter element that prevents dust from falling off.
