[0002] An air filter is a device used to remove solid particles, bacteria, viruses and other pollutants from the air. The main components of an air filter include a housing, a filter element and related filter materials. The housing usually protects internal components and maintains structural stability, while the filter element is a key component for filtering air.

[0003] When the existing equipment is in use, the filter element is usually installed in the inner cavity of the air filter by bolts. However, the filter element needs to be replaced and cleaned frequently, which leads to the bolts being easily stripped after repeated disassembly and assembly, making it inconvenient for people to use. In addition, in the process of removing the filter element for cleaning, a large amount of dust on the surface of the filter element will fall off due to shaking, causing pollution to the surrounding environment.

The positioning plate 4 is fixedly installed at the bottom of the filter element 2, the positioning block 5 is fixedly installed at the bottom of the positioning plate 4, the first positioning groove 6 is opened at the bottom of the housing 1, the second positioning groove 7 is opened at the bottom of the housing 1, and the braking groove 8 is opened at the bottom of the positioning block 5. The transportation mechanism is arranged inside the housing 1, and the shape of the positioning block 5 is set to a convex shape. The shape of the first positioning groove 6 is consistent with the shape of the bottom of the positioning block 5, and the second positioning groove 7 is set to a convex shape. The shape of the groove 7 is set to be an arc, and is adapted to the shape of the positioning block 5. By setting a disassembly and assembly mechanism, the positioning block 5 is aligned with the first positioning groove 6 and moved downward until the positioning block 5 is completely immersed in the first positioning groove 6. A tool such as a hexagon socket is inserted into the inside of the brake groove 8, and the positioning block 5 is twisted to make the positioning block 5 slide from the inside of the first positioning groove 6 to the inside of the second positioning groove 7. Since the shape of the second positioning groove 7 is adapted to the positioning block 5, the positioning block 5 drives the positioning plate 4 and the filter element 2 to be positioned. On the contrary, the positioning block 5 is rotated in the opposite direction to disassemble the filter element 2, so that the installation and disassembly of the filter element 2 do not need to rely on bolts, and the phenomenon of bolt thread slippage is prevented;

[0034] Reference Figure 1-4The transport mechanism includes a transport shell 9 and a transport cavity 10. The transport shell 9 is slidably installed inside the cavity 3. The transport cavity 10 is opened at the bottom of the transport shell 9. The diameter of the transport cavity 10 is larger than the diameter of the filter element 2. Two limiting grooves 11 are opened on the side wall of the shell 1. Limiting blocks 12 are slidably installed inside the two limiting grooves 11. The opposite sides of the two limiting blocks 12 are fixedly connected to the outer wall of the transport shell 9. Two transport blocks 13 are fixedly installed at the bottom of the transport shell 9. A moving groove 14 is opened on the opposite side of the two transport blocks 13. A wedge 15 is slidably installed inside the moving groove 14. The shape of the wedge 15 is set to an arc shape. A spring 16 is fixedly installed on the opposite side of the two moving grooves 14. The other end of the spring 16 is fixedly connected to the wedge 15. A guide rod 17 is fixedly installed on the opposite side of the two wedges 15. The guide rod 17 penetrates to the side of the transport block 13 away from the filter element 2. Two extrusion plates 18 are fixedly installed on the top of the positioning plate 4. The opposite sides of the two extrusion plates 18 are opened The connecting groove 19 is adapted to the wedge block 15. A connecting plate 20 is fixedly installed on the surface of the shell 1. A carrying plate 21 is rotatably installed on the top of the connecting plate 20. By setting a transport mechanism, the carrying plate 21 is rotated so that the carrying plate 21 is no longer in contact with the bottom of the limit block 12, and the limit block 12 is moved downward to drive the transport shell 9 and the transport block 13 to move downward. Since the transport block 13 and the extrusion plate 18 are staggered, and the shape of the wedge block 15 is set to be arc-shaped, the wedge block 15 is squeezed and retracted into the inside of the moving groove 14 until it reaches the preset position. The wedge block 15 is inserted into the inside of the connecting groove 19 through the rebound force of the spring 16. At this time, the filter element 2 is sealed in the inside of the transport shell 9, and the limit block 12 is moved upward, so that the transport shell 9 drives the positioning plate 4 and the filter element 2 to move upward, and then the filter element 2 is moved to the designated position for cleaning, thereby solving the problem that in the prior art, the dust on the surface of the filter element 2 is easily shaken and falls, polluting the environment during the process of cleaning the filter element 2.

[0035] It is worth noting that a sealing gasket is provided on the surface of the transport shell 9, which is in close contact with the inner cavity of the shell 1, and the height of the bottom of the transport shell 9 is lower than the height of the bottom of the limiting groove 11 to prevent the equipment from losing its sealing.

[0036] Specifically, the working process or working principle of the air filter element 2 which is easy to replace is as follows: when in use, the positioning block 5 is aligned with the first positioning groove 6 and moved downward until the positioning block 5 is completely immersed in the first positioning groove 6, and a tool such as an inner hexagon is inserted into the inside of the brake groove 8, and the positioning block 5 is twisted to make the positioning block 5 slide from the inside of the first positioning groove 6 into the inside of the second positioning groove 7. Since the shape of the second positioning groove 7 is compatible with the positioning block 5, the positioning block 5 drives the positioning plate 4 and the filter element 2 to be positioned. On the contrary, the filter element 2 can be disassembled by rotating the positioning block 5 in the opposite direction, and the carrier plate 21 is rotated to make The supporting plate 21 is no longer in contact with the bottom of the limit block 12, and the limit block 12 is moved downward, driving the transport shell 9 and the transport block 13 to move downward. Since the transport block 13 and the extrusion plate 18 are staggered, and the shape of the wedge block 15 is set to be arc-shaped, the wedge block 15 is squeezed and retracted into the inside of the movable groove 14 until it reaches the preset position. The wedge block 15 is inserted into the inside of the connecting groove 19 through the rebound force of the spring 16. At this time, the filter element 2 is sealed inside the transport shell 9, and the limit block 12 is moved upward, so that the transport shell 9 drives the positioning plate 4 and the filter element 2 to move upward, and then the filter element 2 is moved to the designated position for cleaning.
