Description

Technical Field

[0001] The utility model mainly relates to the field of air filter elements, and in particular to an air filter element structure with a self-dust removal function. Background Art

[0002] Air filter is a kind of filter, also called air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. The air filter is mainly used to filter dust, impurities and other particles in the air.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] However, after the air filter has filtered a lot of air, the particles in the air will adhere to the inner wall of the air filter, causing the air filter's filtering effect to decrease. The air filter needs to be removed and replaced or cleaned regularly. The purification device needs to be turned off each time the air filter is cleaned, and disassembling and installing the air filter is rather cumbersome.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0031] See attached Figure 1-4 , an air filter element structure with a self-dust removal function, comprising a filter housing 1, an outer wall of the filter housing 1 is provided with a ventilation groove 2, a mounting structure 3 is provided inside the filter housing 1, a filter element 4 is provided between the mounting structure 3 and the filter housing 1, and a self-cleaning structure 7 is provided on the top of the filter housing 1;

[0032] The mounting structure 3 includes a mounting tube 301, mounting grooves 306 are provided on both sides of the outer wall of the mounting tube 301, a sliding rod 307 is provided on the inner wall of the mounting groove 306, a moving block 309 is slidably connected to the outer wall of the sliding rod 307, a return spring 308 is provided between the moving block 309 and the mounting groove 306, a push rod 310 is rotatably connected to the outer wall of the moving block 309, one end of the push rod 310 is rotatably connected to a pressing plate 311, and the outer wall of the pressing plate 311 is in contact with the inner wall of the filter element 4;

[0033] The self-cleaning structure 7 includes a servo motor 701 . A cam 702 is disposed at the output end of the servo motor 701 . The cam 702 is disposed inside the filter housing 1 . The cam 702 is slidably connected to the pressing plate 311 .

[0034] Furthermore, the number of the air permeable grooves 2 is set to be multiple, and the multiple air permeable grooves 2 are arranged in a circular array on the outer wall of the filter housing 1. The external air enters the interior of the mounting tube 301 and enters the interior of the filter element 4 through the top of the mounting tube 301. The air then flows outward through the inner wall of the filter element 4. Dust will be trapped in the interior of the filter element 4, and the filtered air enters the interior of the air outlet bin 5 through the air permeable grooves 2.

[0035] Furthermore, a bottom plate 302 is provided at the bottom of the mounting tube 301, and the connection position between the bottom plate 302 and the mounting tube 301 is inclined, the top of the bottom plate 302 is fitted with the bottom of the filter element 4, the outer wall of the bottom plate 302 is provided with a spring block 303, and an air inlet pipe 304 is provided at the bottom of the mounting tube 301, and a connecting flange 305 is provided at one end of the air inlet pipe 304. The fitting position of the bottom plate 302 and the filter element 4 is horizontally set. When the filter element 4 is stored, the filter element 4 vibrates, and the vibration causes the dust inside the filter element 4 to fall to the top of the bottom plate 302 and be collected through the bottom plate 302.

[0036] Furthermore, positioning rods 703 are provided on both sides of the bottom of the cam 702, and a rotating ring 704 is provided at the bottom of the positioning rod 703. The rotating ring 704 is rotatably connected to the mounting tube 301, and the outer wall of the rotating ring 704 is provided with fan blades 705. The outer wall of the filter housing 1 is provided with an air outlet bin 5, and the top of the air outlet bin 5 is provided with a connecting pipe 6. During the rotation of the cam 702, the cam 702 drives the rotating ring 704 to rotate through the positioning rod 703, and the rotating ring 704 drives the fan blades 705 to rotate, so that the fan blades 705 draw the air in the mounting tube 301 into between the outer wall of the mounting tube 301 and the filter element 4, so as to suppress the dust and prevent a large amount of dust from entering the interior of the mounting tube 301.

[0037] In this embodiment, when it is necessary to filter the air through the filter element 4, the air pump pumps the external air into the air inlet pipe 304, the air enters the interior of the mounting tube 301 and enters between the outer wall of the mounting tube 301 and the filter element 4 through the opening at the top of the mounting tube 301, and then the air is filtered by the filter element 4 and then enters the interior of the air outlet bin 5 and is discharged through the connecting pipe 6, and the dust in the air is trapped in the interior of the filter element 4;

[0038] When it is necessary to self-clean the dust on the inner wall of the filter element 4, the servo motor 701 is started, and the servo motor 701 drives the cam 702 to rotate. The long side of the cam 702 contacts the pressure plate 311 and pushes the pressure plate 311 to move outward, and then the pressure plate 311 drives the push rod 310 to rotate and pulls the moving block 309 to slide on the outer wall of the slide rod 307, and at the same time, the moving block 309 stretches the return spring 308. When the short side of the cam 702 contacts the pressure plate 311, the return spring 308 drives the moving block 309 to reset and vibrate, so that the pressure plate 311 vibrates and knocks on the inner wall of the filter element 4, so that the dust in the filter element 4 falls off. At the same time, during the rotation of the cam 702, the fan blade 705 on the outer wall of the rotating ring 704 is driven to rotate through the positioning rod 703, the air of the mounting tube 301 is extracted, and the dust between the outer wall of the mounting tube 301 and the filter element 4 is suppressed to prevent excessive dust from entering the interior of the mounting tube 301.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
