Description

Technical Field

[0001] The utility model belongs to the technical field of air filters, in particular to a low-resistance high-efficiency air filter. Background Art

[0002] Low-resistance high-efficiency air filters can effectively remove tiny particles in the air and significantly improve the air quality indoors or in specific working environments. This is of great significance for protecting human health, preventing respiratory diseases, and reducing allergic reactions, especially in places with poor air quality or strict requirements on cleanliness. In the prior art, a filter element holder is usually provided inside the box, and a filter element is provided on the filter element holder to efficiently filter the air. However, in this method, a pre-treatment component is not provided in front of the box, and the air contains larger dust particles and some impurities. These large particles may quickly fill the filter material of the high-efficiency filter, causing it to clog prematurely, increasing the frequency of cleaning or replacement, and shortening the actual service life of the high-efficiency filter.

[0003] For example, the utility model with announcement number CN216986880U discloses a low-resistance high-efficiency air filter. In the technical solution of this patent, a box cover is detachably installed at the end of the box body, a filter element is arranged between the box body and the box cover, and a filter element holder is arranged on the surface of the filter element to filter the material. However, in this method, a pre-filter element is not arranged in front of the box body, and the air contains larger dust particles and some impurities, which may cause a large amount of coarse particles to adhere to the surface of the high-efficiency filter and form a layer of "dust cake". Although it can capture some fine particles to a certain extent, it may also change the air flow path, resulting in local airflow short-circuiting, reducing the uniformity and filtration efficiency of the entire filtration system. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a low-resistance high-efficiency air filter, which can not only intercept larger dust particles and some impurities in the air through the pre-filter plate to reduce the workload of the high-efficiency filter, but also clean the pre-filter plate through the cleaning component to avoid the entire filter reaching its saturation point prematurely due to rapid clogging of the pre-filter layer, thereby extending the overall service life of the high-efficiency filter.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a low-resistance high-efficiency air filter, including a box body, an air inlet is arranged at the left end of the box body, an air outlet is arranged at the right end, a groove is arranged at the left end of the box body, a pre-filter plate is slidably arranged inside the groove, a cleaning assembly is arranged at the left end of the pre-filter plate, and a box door is hinged at the upper end of the box body, and a handle is arranged on the box door.

[0006] As a further improvement of the utility model, the cleaning assembly includes a sliding rod arranged inside the box body, a mounting frame is slidably arranged on the sliding rod, a rotating column is rotatably arranged inside the mounting frame, a brush for cleaning the pre-filter plate is arranged on the outer arc surface of the rotating column, a driving member 1 for driving the mounting frame to move up and down is arranged on the top of the box body, and a driving member 2 for driving the rotating column to rotate is arranged on the left side wall of the groove.

[0007] As a further improvement of the utility model, the driving member includes a slide groove arranged on the upper side wall of the box body, a threaded rod is rotatably arranged inside the slide groove, a slider is threadedly connected to the threaded rod, a rotating plate is rotatably connected to the lower end of the slider, a rotating seat is arranged at the upper end of the mounting frame, and the end of the rotating plate away from the slider is rotatably connected to the rotating seat.

[0008] As a further improvement of the utility model, the second driving member includes a rack plate arranged on the left side wall of the groove, and a gear meshing with the rack plate is arranged on the rotating column.

[0009] As a further improvement of the utility model, a motor is arranged at the rear side of the box body, and the output end of the motor is connected to the rotating column through a coupling.

[0010] As a further improvement of the utility model, a plurality of filter elements are arranged inside the box body to further filter the air. A through hole is arranged at the lower end of the box body, and the through hole is located at the lower side of the brush. A material collecting box is arranged at the lower side of the through hole so that the cleaned dust and particles can fall into the material collecting box through the through hole to avoid polluting the air.

[0011] As a further improvement of the utility model, a plurality of universal wheels are arranged at the lower end of the box body, and brake pads are arranged on the universal wheels.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] Firstly, by setting up a cleaning component, starting the motor can rotate the threaded rod, and the rotation of the threaded rod can make the slider move along the slide groove, and then the rotating plate rotates. The rotation of the rotating plate makes the mounting frame move up and down along the sliding rod so as to move the brush up and down. In the process of the mounting frame moving up and down, the gear on the rotating column rotates along the rack plate, and then the rotating column drives the brush to rotate, so that the brush cleans the pre-filter plate. The pre-filter plate, as the first line of defense of the high-efficiency filter, is responsible for intercepting larger particulate pollutants and some fine particles. Regular cleaning of the pre-filter plate can remove a large amount of dust and debris accumulated on its surface, reduce the burden on the subsequent filter layer, and avoid the entire filter reaching its saturation point prematurely due to too fast clogging of the pre-filter layer, thereby extending the overall service life of the high-efficiency filter.

[0014] Secondly, by setting up a pre-filter plate, larger dust particles and some impurities in the air are first intercepted, which greatly reduces the workload of the high-efficiency filter.

[0015] Thirdly, by setting universal wheels, the high-efficiency air filter has good mobility, which makes it convenient to move the filter to the designated location quickly and flexibly when the position needs to be adjusted, without consuming a lot of manpower.

[0016] Fourthly, by providing a brake pad, after the filter is moved to a suitable position, the filter can be fixed by locking the brake pad to prevent it from accidentally sliding or moving. BRIEF DESCRIPTION OF THE DRAWINGS

Regular cleaning of the pre-filter plate 105 can remove a large amount of dust and debris accumulated on its surface, reduce the burden on the subsequent filter layer, and avoid the entire filter from reaching its saturation point prematurely due to excessive clogging of the pre-filter layer, thereby extending the overall service life of the high-efficiency filter.

[0027] like Figure 1 , 2As shown, a plurality of filter elements 301 are arranged inside the box body 101 to further filter the air, a through hole 303 is arranged at the lower end of the box body 101, the through hole 303 is located at the lower side of the brush 204, and a collecting box 302 is arranged at the lower side of the through hole 303, so that the cleaned dust and particles can fall into the collecting box 302 through the through hole 303 to avoid polluting the air.

[0028] Working principle: When using the device, the air first passes through the pre-filter plate 105 to intercept larger dust particles and some impurities in the air, greatly reducing the workload of the high-efficiency filter, and then passes through the filter element 301 to further filter the air. During the filtering process, starting the motor 211 can rotate the threaded rod 206, and the rotation of the threaded rod 206 can cause the slider 207 to move along the slide groove 205, thereby causing the rotating plate 208 to rotate. The rotation of the rotating plate 208 causes the mounting frame 202 to move up and down along the sliding rod 201, so that the brush 204 moves up and down, and the mounting frame 202 moves up and down. During the cleaning process, the gear 210 on the rotating column 203 rotates along the rack plate 209, thereby causing the rotating column 203 to drive the brush 204 to rotate, so that the brush 204 can clean the pre-filter plate 105. The pre-filter plate 105, as the first line of defense of the high-efficiency filter, is responsible for intercepting larger particle pollutants and some fine particles. Regular cleaning of the pre-filter plate 105 can remove a large amount of dust and debris accumulated on its surface, reduce the burden on subsequent filter layers, and avoid the entire filter reaching its saturation point prematurely due to excessive clogging of the pre-filter layer, thereby extending the overall service life of the high-efficiency filter.
