Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a self-cleaning device for an air filter. Background Art

[0002] An air filter is a device used to remove pollutants such as dust, particulate matter, bacteria, viruses, etc. from the air. It plays an important role in various application scenarios such as air purification, air conditioning systems, industrial ventilation, and clean rooms. The air filter consists of an external shell and an internal filter element to filter out dust in the air when the air passes through the air filter, thereby improving air cleanliness and meeting the air quality requirements in life and production.

[0003] After the air filter element is used for a long time, a large amount of impurities will accumulate on its outside, affecting the air permeability and filtration quality of the filter element. Therefore, the filter element needs to be replaced or cleaned to maintain the air filtration function at the desired level. Since the impurities on the outside of the filter element do not affect the structure of the filter element itself, it is more economical to clean the old filter element than to replace it with a new one. The current method of cleaning and maintaining the filter element requires stopping the air filter and removing the filter element. The air filter can only be operated again after cleaning and installing the filter element. This process is relatively cumbersome, consumes manpower and material resources, and has low filter element cleaning efficiency.

[0004] Therefore, the present application provides a self-cleaning device for an air filter to meet the needs. Utility Model Content

[0034] As an implementation method in this embodiment, in order to facilitate the connection between the fastener 2 and the filter element 5, as shown in FIG. Figure 4 、 Figure 6 As shown, a buckle cover 21 is provided at the center of the fastener 2, and the buckle cover 21 is used to buckle on the bottom of the filter element 5.

The air enters the shell 1 from the air inlet pipe 10, is filtered by the filter element 5 and is discharged from the air outlet pipe 11. The impurities in the air are blocked on the outer wall of the filter element 5. When the filter element 5 needs to be cleaned, the motor 3 is started, driving the cam 30 to rotate, and the lever 31 rotates and moves back and forth in the slide 40, so that the ring cover 4 also reciprocates, and the ring frame 42 is driven to reciprocate through the support rod 41, driving the cleaning frame 43 cleans the outer wall of the filter element 5 reciprocally, and the impurities accumulated and attached on the filter element 5 are swept away. The reciprocating motion of the ring cover 4 generates air flow at the annular groove, so that the impurities swept away in the shell 1 are discharged with the air flow, avoiding the accumulation of impurities. The support rod 41 moves along the guide bar 12, thereby enhancing the stability of the reciprocating motion. The bracket 20 connects the fastener 2 and the buckle cover 21, enhancing the structural strength of the buckle cover 21 on the fastener 2. The positioning block 22 can be easily plugged and aligned with the inner periphery of the filter element 5, which is beneficial to the quick alignment of the filter element 5 during installation. After cleaning is completed, the motor 3 is reset, the ring cover 4 is reset, and the bottom of the shell 1 is closed.
