Detailed implementation mode

[0019] In order to further understand the invention content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 4 shown, an air purifier with a matching function provided by an embodiment of the present utility model includes a purifier housing 1 and a filter cartridge 2. The filter cartridge 2 is arranged in the inner cavity of the purifier housing 1. A filter cotton and an ultraviolet germicidal lamp are arranged in the inner cavity of the filter cartridge 2. A dust suction hood 3 is sleeved on the surface of the filter cartridge 2. An air suction pump 4 is arranged on the right side of the dust suction hood 3. A positioning device 5 is arranged on the left side of the purifier housing 1.

[0022] Referring to Figure 4 , the positioning device 5 includes a positioning block 501. A stable hole 502 is formed on the surface of the positioning block 501. A stable block 503 that cooperates with the stable hole 502 is fixedly connected to the left side of the purifier housing 1. The surface of the stable block 503 is movably connected to the inner cavity of the stable hole 502. A spring 504 is fixedly connected to the surface of the positioning block 501. The bottom of the spring 504 is fixedly connected to the top of the stable block 503.

[0023] Adopting the above scheme: By setting the positioning device 5, when the dust suction hood 3 moves to a suitable height position, the positioning device 5 has a limiting effect on the position of the dust suction hood 3.

[0024] Referring to Figure 2 , a control gear disk 6 is movably connected to the inner cavity of the purifier housing 1 through a rotating shaft. The left side of the control gear disk 6 penetrates through the purifier housing 1 and extends to the outside of the inner cavity of the purifier housing 1. A rotating gear disk 7 that cooperates with the control gear disk 6 is movably connected to the inner cavity of the purifier housing 1 through a rotating shaft. The surface of the control gear disk 6 is meshed with the surface of the rotating gear disk 7. The surface of the control gear disk 6 is in contact with the surface of the positioning block 501.

[0025] Adopting the above scheme: By setting the control gear disk 6 and the rotating gear disk 7, when the control gear disk 6 is rotated, the rotational force generated by the control gear disk 6 on the rotating gear disk 7 can drive the rotating gear disk 7 to rotate through the rotating shaft. When the rotating gear disk 7 rotates, it can drive a threaded rod 9 to rotate.

[0026] Referring to Figure 4 , a positioning groove 8 that cooperates with the positioning block 501 is formed on the top of the control gear disk 6. The surface of the positioning block 501 is in contact with the inner cavity of the positioning groove 8. The number of the positioning grooves 8 is several and they are evenly distributed on the top of the control gear disk 6.

[0027] Adopt the above solution: By setting the positioning groove 8, when the control gear disk 6 rotates to a suitable position, release the positioning block 501, and the restoring force generated by the spring 504 restoring its shape will drive the positioning block 501 to snap into the inner cavity of the positioning groove 8. The cooperation of the positioning block 501 and the positioning groove 8 has a limiting effect on the position of the control gear disk 6.

[0028] Reference Figure 2 , a threaded rod 9 is fixedly connected to the top of the rotating gear disk 7, and a threaded housing 10 that cooperates with the threaded rod 9 is fixedly connected to the left side of the dust suction hood 3. The inner cavity of the threaded housing 10 is meshed with the surface of the threaded rod 9.

[0029] Adopt the above solution: By setting the threaded rod 9 and the threaded housing 10, when the threaded rod 9 rotates, it can drive the threaded housing 10 to move up or down. When the threaded housing 10 moves, it can drive the dust suction hood 3 to move up or down.

[0030] Reference Figure 3 , an annular brush 11 is fixedly connected to the top of the dust suction hood 3, and the surface of the annular brush 11 is in contact with the surface of the filter cartridge 2.

[0031] Adopt the above solution: By setting the annular brush 11, when the dust suction hood 3 moves, it can drive the annular brush 11 to move along the surface of the filter cartridge 2, and the annular brush 11 can sweep off the dust adhering to the surface of the filter cartridge 2.

[0032] Reference Figure 3 , a dust collection box 12 is arranged at the dust outlet of the air suction pump 4, and a ventilation net is arranged at the top of the dust collection box 12.

[0033] Adopt the above solution: By setting the dust collection box 12, the dust collection box 12 can collect the dust discharged from the dust outlet, effectively preventing the dust from returning to the inner cavity of the purifier housing 1 again.

[0034] The working principle of the present utility model:

[0035] During use, when the filter cartridge 2 used in the air purifier needs to be cleaned conveniently, first, the user pulls the positioning block 501 upward. When the positioning block 501 moves, it will drive the stabilizing hole 502 to move along the surface of the stabilizing block 503. The force generated when the positioning block 501 moves causes the spring 504 to undergo elastic deformation. When the positioning block 501 disengages from the contact with the inner cavity of the positioning groove 8, the control gear disk 6 can be rotated. When the control gear disk 6 rotates, it will drive the rotating gear disk 7 to rotate through the rotating shaft. When the rotating gear disk 7 rotates, it will drive the threaded rod 9 to rotate along the inner cavity of the threaded housing 10. The rotation of the threaded rod 9 will drive the threaded housing 10 to move upward or downward. When the threaded housing 10 moves, it can drive the dust suction hood 3 to move downward or upward along the surface of the filter cartridge 2, and at the same time drive the annular brush 11 to move along the surface of the filter cartridge 2. The annular brush 11 will shed the dust adhering to the surface of the filter cartridge 2. Then, the suction pump 4 is started. The suction port of the suction pump 4 will make the inner cavity of the dust suction hood 3 have suction. At this time, the suction pump 4 will suck the dust swept by the annular brush 11 through the dust suction hood 3, and then collect it into the inner cavity of the dust collection box 12 through the dust outlet. When the dust on the surface of the filter cartridge 2 is cleared, the dust suction hood 3 is moved to the top of the surface of the filter cartridge 2, and then the positioning block 501 can be released. The restoring force generated when the spring 504 resumes its shape will drive the positioning block 501 to snap into the inner cavity of the positioning groove 8, and the position of the dust suction hood 3 will be fixed, which will not affect the normal operation of the filter net. When the dust in the dust collection box 12 accumulates too much, the dust collection box 12 can be removed for cleaning. At this time, the filter cartridge 2 used in the air purifier is conveniently cleaned.

[0036] In summary: For this air purifier with a matching function, by setting the combined use of the positioning block 501, stabilizing hole 502, stabilizing block 503, spring 504 and positioning groove 8, it solves the problem that the filter cartridge of the existing air purifier is a key component responsible for capturing and filtering pollutants in the air. Polluted air enters the inner cavity of the machine body through the air inlet hole. Over time, these pollutants will adhere to the surface of the filter cartridge. If not cleaned in time, it is likely to cause a decline in the filtering efficiency of the filter cartridge. At the same time, it will lead to the accumulation and reproduction of pollutants, releasing more harmful substances. When cleaning the existing filter cartridge, the outer shell of the air purifier needs to be disassembled, and then the filter cartridge needs to be removed. This cleaning method takes a long time, has low efficiency and is not convenient enough. However, the existing air purifier does not have a component for conveniently cleaning the filter cartridge, resulting in an increased replacement frequency of the filter cartridge.
