Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to an air purification filter which is easy to clean. Background Art

[0002] An air purification filter is a core component of a device or apparatus used to remove pollutants such as solid particles, gaseous pollutants, bacteria and viruses from the air. Its main function is to reduce or eliminate pollutants in the air through physical, chemical or biological processes, thereby improving air quality.

[0003] At present, in the prior art, for example, a Chinese patent with announcement number CN220287682U discloses an air filter that is easy to clean. The device is provided with a cleaning mechanism. When a lot of dust and lint adhere to the surface of the filter, the motor can be used to drive the screw rod to rotate, so that the screw rod drives the slider to slide up and down on the screw rod, thereby driving the cleaning brush to brush up and down on the filter, and the dust on the filter is brushed off and dropped into the collection box under the filter. The staff can regularly pull out the collection box for cleaning, which is convenient for quickly cleaning the filter. However, when the cleaning brush is cleaning, a large amount of impurities will adhere to the cleaning brush. This device cannot clean the impurities on the cleaning brush, thereby affecting the cleaning effect of the cleaning brush. In view of this, we propose an air purification filter that is easy to clean. Utility Model Content

A collection box 3 and a cleaning device 5 are provided inside the shell 1. The cleaning device 5 includes a motor 51, the motor 51 is fixedly connected to the outer wall of the shell 1, and a reciprocating screw 52. The reciprocating screw 52 passes through the shell 1 and is rotatably connected to the shell 1. The reciprocating screw 52 and The output end of the motor 51 is fixedly connected, the moving block 53 is penetrated by the reciprocating screw 52 and is threadedly connected to the reciprocating screw 52, ​​the moving block 53 is slidably connected to the slide groove 41, the slider 54 is slidably connected to the moving block 53, the moving rod 55 is fixedly connected to the slider 54, the brush 56 is penetrated by the moving rod 55 and is slidably connected to the moving rod 55, and the spring four 57, one end of the spring four 57 is fixedly connected to the moving rod 55, and the other end of the spring four 57 is fixedly connected to the inner wall of the brush 56;

[0035] like Figure 2 and Figure 3 As shown, when the motor 51 is started, the reciprocating screw 52 rotates. During this process, the moving block 53 drives the brush 56 to move toward the motor 51, so that the brush 56 can clean the filter screen 4.

[0036] In the embodiment of the present utility model, in order to be able to clean the brush 56, specifically, the outer wall of the slider 54 is fixedly connected with a spring 1 532, and the end of the spring 1 532 away from the slider 54 is fixedly connected to the inner wall of the moving block 53, the slider 54 is slidably connected with a clamping block 541, the outer wall of the clamping block 541 is fixedly connected with a spring 3 542, and the end of the spring 3 542 away from the clamping block 541 is fixedly connected to the inner wall of the slider 54, the moving block 53 is provided with a through groove 531 and a limiting groove 533, the limiting groove 533 is slidably connected with a push plate 534, the outer wall of the push plate 534 is fixedly connected with a spring 2 535, and the end of the spring 2 535 away from the push plate 534 is fixedly connected to the inner wall of the moving block 53, the outer wall of the push plate 534 is fixedly connected with a push rod 536, and the push rod 536 is slidably connected to the moving block 53;

[0037] When the moving block 53 moves to the motor 51, the inclined block 44 enters the through slot 531, and the inclined block 44 squeezes the slider 54, so that the slider 54 slides inside the moving block 53. At the same time, the moving block 53 squeezes the clamping block 541, so that it completely enters the slider 54. When the clamping block 541 coincides with the limiting slot 533, the clamping block 541 will be elastically moved into the limiting slot 533 under the action of the spring 3 542, so that the brush 56 can be limited.

At this time, the block 541 is completely separated from the limit groove 533. At this time, the brush 56 will return to its original position under the elastic force of the spring 1 532.

[0041] In the utility model, during use, when the motor 51 is started, the moving block 53 will drive the brush 56 to move toward the motor 51, so that the brush 56 can clean the filter screen 4. When the moving block 53 moves to the motor 51, the cleaning teeth 43 are inserted into the inside of the brush 56. At the same time, the inclined block 44 will squeeze the slider 54, so that the brush 56 moves, so that the cleaning teeth 43 can clean the fluff on the brush 56. When the brush 56 is limited, the moving block 53 returns to its original position under the drive of the motor 51. During this process, the outer wall of the brush 56 is squeezed by the protrusion 42. When the brush 56 is separated from the protrusion 42, the brush 56 will vibrate up and down under the elastic force of the spring four 57, so that the dust on the brush 56 can be cleaned.
