[0004] In view of the shortcomings of the prior art, this utility model provides an air purification device for public places that is easy to disassemble, and has the advantages of high filter disassembly efficiency, thus solving the problem of slow filter disassembly in the prior art.

[0005] To achieve the above-mentioned goal of high efficiency in disassembling the filter, this utility model provides the following technical solution: an air purification device for public places that is easy to disassemble, including an air purification shell, a filter installed inside the air purification shell, a positioning component movably installed inside the air purification shell, and an annular groove opened on the top of the air purification shell;

[0006] The positioning component includes a rotating cylinder. The rotating cylinder is movably mounted on the bottom of the air purifier housing. A threaded rod is provided on the top of the rotating cylinder. A threaded ring is threadedly connected to the outside of the threaded rod. A limiting hinge block is provided outside the threaded ring. A limiting cylinder is provided inside the air purifier housing. The threaded rod and the threaded ring are sleeved inside the limiting cylinder. A hinge rod is provided at the end of the limiting hinge block. A filter screen is provided at the other end of the hinge rod.

[0007] Furthermore, both ends of the hinge rod are provided with limit hinge blocks, and the end of the limit hinge block away from the threaded ring is provided with a insertion groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This easily detachable air purification device for public places features a positioning component. When the filter needs to be removed, rotating the rotating cylinder drives the threaded rod to rotate. Due to the limiting effect of the limiting groove and the limiting cylinder on the limiting hinge block and the threaded ring, the threaded ring can move upward on the outer surface of the threaded rod, causing the hinge rod and the filter to tilt. At this time, the hinge rod will pull the filter to the center. After moving to the position below the annular groove, the top of the telescopic structure will not be limited, causing the spring to extend and push the protrusion to extend into the annular groove. The filter can be removed from the air purification housing through the protrusion, realizing the function of quick filter removal.

[0016] This easily detachable air purification device for public places prevents air leakage during operation by setting a sealing ring inside the annular groove. The filter can be removed from the annular groove after the sealing ring is removed. With the setting of a fixing column and base, the operator can directly rotate and adjust the rotating drum between the air purification shell and the base. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An easily detachable air purification device for public places in this embodiment includes an air purification housing 1, a filter 4 installed inside the air purification housing 1, a positioning component 7 movably installed inside the air purification housing 1, and an annular groove 11 opened on the top of the air purification housing 1.

[0024] The positioning component 7 includes a rotating cylinder 701. The rotating cylinder 701 is movably mounted on the bottom of the air purification housing 1. A threaded rod 702 is provided on the top of the rotating cylinder 701. A threaded ring 705 is threadedly connected to the outside of the threaded rod 702. A limiting hinge block 706 is provided on the outside of the threaded ring 705. A limiting cylinder 703 is provided inside the air purification housing 1. The threaded rod 702 and the threaded ring 705 are sleeved inside the limiting cylinder 703. A hinge rod 704 is provided at the end of the limiting hinge block 706. A filter screen 4 is provided at the other end of the hinge rod 704.

[0025] In the implementation of the case, by setting the positioning component 7, when the filter screen 4 needs to be removed, the rotating cylinder 701 drives the threaded rod 702 to rotate. Due to the limiting effect of the limiting groove 8 and the limiting cylinder 703 on the limiting hinge block 706 and the threaded ring 705, the threaded ring 705 can move upward at the outer surface of the threaded rod 702, so that the hinge rod 704 and the filter screen 4 are hinged and tilted. At this time, the hinge rod 704 will pull the filter screen 4 to move towards the middle. After moving to the position below the annular groove 11, the top of the telescopic structure 9 will not be limited, which will cause the spring to extend and push the protrusion to extend into the annular groove 11. The filter screen 4 can be removed from the air purification housing 1 through the protrusion, realizing the function of quickly disassembling the filter screen 4.

[0026] Furthermore, by setting the sealing ring 5 inside the annular groove 11, air leakage can be prevented during the operation of the air purifier. The filter 4 can be removed from the annular groove 11 by removing the sealing ring 5. By setting the fixing column 2 and the base 3, the operator can directly rotate and adjust the rotating drum 701 between the air purifier housing 1 and the base 3.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, remove the sealing ring 5 from the annular groove 11;

[0029] 2) Then rotate the rotating drum 701, which drives the filter screen 4 to move towards the center through the positioning component 7;

[0030] 3) When the filter screen 4 and the telescopic structure 9 move into the annular groove 11;

[0031] 4) Finally, the telescopic spring will push the protrusion upward into the annular groove 11. The filter 4 can be removed from the air purification housing 1 for disassembly and replacement through the protrusion.

[0032] In summary, this easily detachable air purification device for public places, by setting up a positioning component 7, allows the filter 4 to be removed when the rotating cylinder 701 drives the threaded rod 702 to rotate. Due to the limiting effect of the limiting groove 8 and the limiting cylinder 703 on the limiting hinge block 706 and the threaded ring 705, the threaded ring 705 can move upward at the outer surface of the threaded rod 702, causing the hinge rod 704 to be hinged and tilted with the filter 4. At this time, the hinge rod 704 will pull the filter 4 to move towards the middle. After moving to the position below the annular groove 11, the top of the telescopic structure 9 will not be limited, causing the spring to extend and push the protrusion to extend into the annular groove 11. The filter 4 can be removed from the air purification housing 1 through the protrusion, realizing the function of quickly removing the filter 4.

[0033] Furthermore, by setting the sealing ring 5 inside the annular groove 11, air leakage can be prevented during the operation of the air purifier. The filter 4 can be removed from the annular groove 11 by removing the sealing ring 5. By setting the fixing column 2 and the base 3, the operator can directly rotate and adjust the rotating drum 701 between the air purifier housing 1 and the base 3.
