Description

Technical Field

[0001] The present invention relates to the technical field of air filter cleaning, and specifically relates to an efficient cleaning device for automotive air filters. Background Art

[0002] The internal structure of an air filter usually consists of filter media, a support skeleton, a sealing ring, a housing, etc. The main part of an air filter is usually composed of synthetic fibers (such as polyester fibers), paper filter media, or non-woven fabrics, etc. These materials have good filtering performance and can effectively capture dust, particles, and pollutants in the air.

[0003] After retrieval, the existing publication number CN115301008B discloses a compressor air filter, which includes a base, an inner filter cylinder, an outer filter cylinder, and a housing. The inner filter cylinder and the outer filter cylinder are both vertically arranged on the top of the base, the outer filter cylinder covers the inner filter cylinder, filter meshes are arranged on the inner sides of the inner filter cylinder and the outer filter cylinder, the housing covers the outer filter cylinder and is detachably connected to the base, an air inlet pipe is communicatively arranged on the base, an air outlet pipe is communicatively arranged on the top of the housing, and a knocking mechanism for knocking the inner filter cylinder and the outer filter cylinder is arranged on the base. By providing an air filter that can knock the inner filter cylinder and the outer filter cylinder, the excessive accumulation of dust on the filter cylinder and the filter mesh is effectively avoided, and thus the blockage of the filter cylinder and the filter mesh is effectively avoided, ensuring the normal working state of the air filter. At the same time, by providing a detachable housing, it is convenient for workers to clean the dust accumulated inside the air filter.

[0004] Since the air flow enters from the inside of the filter element, and the surface structure of the filter element is mesh-shaped, the dust and other foreign matters in the air flow are also filtered and adhered to the inner wall of the mesh holes or the inner side of the filter element (not inside the mesh holes). Only by using the knocking method in the above technical solution, although the dust and other foreign matters can be cleaned from the inner wall of the mesh holes or the surface of the filter element, the filter element still needs to be removed to remove the cleaned dust and other foreign matters, and the cleaned dust and other foreign matters cannot be automatically transported to the outside of the filter element by the reverse air flow. Summary of the Invention

[0005] The purpose of the present invention is to provide an efficient cleaning device for automotive air filters, aiming to solve the problems existing in the existing compressor air filters.

[0006] To achieve the above purpose, the present invention provides the following technical solution. An efficient cleaning device for automotive air filters includes an air filter, and further includes:

[0047] Please refer to Figure 3 and Figure 5 In an embodiment of the present invention, one end of the air filter element 3 facing away from the detachable sealing cover 11 is movably sleeved on the surface of the first pipe body 21. A first key strip 27 and a first key groove are respectively provided on the surface of the first pipe body 21 and the inner side of the air filter element 3.

[0048] In an embodiment of the present invention, on the one hand, the rotating first pipe body 21 controls the rotation of the air filter element 3 through the first key strip 27 and the first key groove. The frictional force generated between the rotating air filter element 3 and the air flow helps to clean foreign matters such as dust.

[0049] Please refer to Figure Figure 7 In an embodiment of the present invention, a bracket is fixedly connected to the surface of the spherical pipe body 22, an electromagnet 28 is embedded on the surface of the bracket, a second key strip 441 and a second key groove are respectively provided on the surfaces of the rotating shaft 44 and the transmission gear 45. The second key strip 441 is in sliding connection with the second key groove. A second spring 29 is connected between the bracket and the transmission gear 45, and a limiting block 442 is fixedly connected to the surface of the rotating shaft 44.

[0050] In an embodiment of the present invention, the transmission gear 45 is made of metal. The energized electromagnet 28 can magnetically adsorb the transmission gear 45. When the electromagnet 28 is powered off, the elastic force of the second spring 29 drives the transmission gear 45 to move to a position where it fits with the limiting block 442. At this time, the transmission gear 45 is in transmission connection with the first tooth rail 15.

[0051] Working principle: When cleaning the air filter element 3, first, the driving member 5 and the transmission connection of the second tooth rail 24 are used to control the rotation of the rotary pipe fitting 2 and the air flow guiding part 4. The rotating air flow guiding part 4 uses the transmission connection between the transmission gear 45 and the first tooth rail 15 to control the sphere 41 to rotate 90 degrees around the rotating shaft 44, so that the air outlet channel 43 is aligned with the slag discharge port 23.

[0052] Then, control the electromagnet 28 to be energized. Since the energized electromagnet 28 magnetically adsorbs the transmission gear 45, the transmission gear 45 moves along the rotating shaft 44 to a position disengaged from the first tooth rail 15. Then, the driving member 5 is used again to control the rotation of the rotary pipe fitting 2 and the air flow guiding part 4. The rotating first pipe body 21, on the one hand, controls the rotation of the air filter element 3 through the first key strip 27 and the first key groove, and on the other hand, controls the vibration ring 61 and the air filter element 3 to vibrate up and down at a certain frequency through the sliding connection between the vibration ring 61 and the curve guide rail 25 and the downward elastic force of the first spring 13. Immediately afterwards, close the control valves at the connection between the three-way pipe 111 and the air duct and the connection between the air inlet pipe 26 and the air inlet device, and open the control valve at the connection between the three-way pipe 111 and the air inlet device, so that the air flow reversely enters the air filter element 3. The air flow reversely entering the air filter element 3, combined with the vibration of the air filter element 3 and the friction force between the rotating air filter element 3 and the air flow, can more efficiently and thoroughly remove foreign matters such as dust inside the air filter element 3. Finally, the air flow mixed with foreign matters such as dust is discharged outwards through the air outlet channel 43 and the slag discharge port 23, featuring automatic and efficient cleaning of the air filter element 3.

[0053] In summary, the present application uses the structural design of the mutual cooperation of the sealing cylinder 1, the rotary pipe fitting 2, the driving member 5, the vibrating member 6 and the air flow guiding part 4, which can not only adjust the flow direction of the air flow, but also use the air flow reversely entering the air filter element 3, combined with the vibration of the air filter element 3 and the friction force between the rotating air filter element 3 and the air flow, to more efficiently and thoroughly remove foreign matters such as dust inside the air filter element 3. Finally, the air flow mixed with foreign matters such as dust is discharged outwards through the air outlet channel 43 and the slag discharge port 23, featuring automatic and efficient cleaning of the air filter element 3.

These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.

[0055] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
