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

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an air purification device with a replacement structure provided by an embodiment of the utility model includes a purification body 1 and a cover 2, the front side of the purification body 1 is movably connected to the rear side of the cover 2, the inner cavity of the purification body 1 is movably connected with a filter screen 3, an installation groove 4 is opened inside the purification body 1, the inner cavity of the installation groove 4 is movably connected with four control blocks 5, the front side of the control block 5 passes through the installation groove 4 and extends to the outside of the inner cavity of the installation groove 4, and four limit devices 6 are arranged inside the installation groove 4.

[0022] refer to Figure 4 The limiting device 6 includes a limiting block 601, and the side of the limiting block 601 close to the filter screen 3 passes through the device groove 4 and extends to the outside of the inner cavity of the device groove 4. The side of the limiting block 601 away from the filter screen 3 is fixedly connected with a spring 602, and the side of the spring 602 away from the filter screen 3 is fixedly connected to the inner cavity of the device groove 4, and the side of the limiting block 601 away from the filter screen 3 is fixedly connected with an outer shell 603.

[0023] With the above solution, by providing the limiting device 6 , when the filter screen 3 moves to the inner cavity of the purifier body 1 , the limiting device 6 has a limiting effect on the position of the purifier body 1 .

[0024] refer to Figure 4 The inner cavity of the device groove 4 is fixedly connected to the inner shell 7 used in conjunction with the outer shell 603, the surface of the inner shell 7 is movably connected to the inner cavity of the outer shell 603, and the side of the inner shell 7 away from the filter screen 3 is fixedly connected to the inner cavity of the device groove 4.

[0025] The above solution is adopted: by setting the inner shell 7, when the limit block 601 moves, the outer shell 603 can be driven to move along the surface of the inner shell 7, and the cooperation of the inner shell 7 and the outer shell 603 has a limiting effect on the moving position of the limit block 601.

[0026] refer to Figure 4 The inner cavity of the device groove 4 is movably connected to an extrusion rotating block 8 used in conjunction with the control block 5 through a rotating shaft. The surface of the extrusion rotating block 8 contacts the surface of the control block 5, and the rear side of the extrusion rotating block 8 contacts the front side of the limit block 601.

[0027] The above solution is adopted: by setting the extrusion rotating block 8, the extrusion force generated on the extrusion rotating block 8 when the control block 5 moves can drive the extrusion rotating block 8 to rotate through the rotating shaft. When the extrusion rotating block 8 rotates, the extrusion hole 9 can be driven to rotate along the surface of the extrusion block 10.

[0028] refer to Figure 4 An extrusion hole 9 is provided on the surface of the extrusion rotating block 8, and an extrusion block 10 used in conjunction with the extrusion hole 9 is fixedly connected to the front side of the limiting block 601, and the surface of the extrusion block 10 is movably connected to the inner cavity of the extrusion hole 9.

[0029] The above scheme is adopted: by setting the extrusion hole 9 and the extrusion block 10, when the extrusion rotating block 8 rotates, the extrusion hole 9 will be driven to rotate along the surface of the extrusion block 10, and the extrusion force of the extrusion hole 9 on the extrusion block 10 can drive the extrusion block 10 to move, and when the extrusion block 10 moves, it can drive the limit block 601 to move.

[0030] refer to Figure 3 A moving hole 11 is opened on the front side of the control block 5, and a moving block 12 used in conjunction with the moving hole 11 is fixedly connected to the inner cavity of the device slot 4, and the surface of the moving block 12 is movably connected to the inner cavity of the moving hole 11.

[0031] The above solution is adopted: by setting the moving hole 11 and the moving block 12, when the control block 5 moves, the moving hole 11 can be driven to move along the surface of the moving block 12. The coordinated use of the moving hole 11 and the moving block 12 has a limiting effect on the moving position of the control block 5.

[0032] refer to Figure 2 The top and bottom of the filter screen 3 are both provided with two limiting grooves 13 used in conjunction with the limiting block 601 , and the surface of the limiting block 601 is in contact with the inner cavity of the limiting groove 13 .

[0033] The above scheme is adopted: by setting the limit groove 13, when the filter 3 moves to the inner cavity of the purification body 1, the control block 5 is released, and the restoring force generated by the spring 602 restoring its shape will drive the limit block 601 to be stuck into the inner cavity of the limit groove 13. The coordinated use of the limit block 601 and the limit groove 13 has a limiting effect on the position of the filter 3.

[0034] The working principle of this utility model:

[0035] When in use, when the filter screen 3 of the air purifier needs to be replaced more stably, the operator first pulls the control block 5 to the opposite side of the two control blocks 5, and the movement of the control block 5 drives the moving hole 11 to move along the surface of the moving block 12. When the control block 5 moves, the extrusion force generated on the extrusion rotating block 8 will drive the extrusion rotating block 8 to rotate through the rotating shaft. When the extrusion rotating block 8 rotates, it will generate an extrusion force on the extrusion block 10. The extrusion block 10 subjected to the extrusion force will move to the side away from the filter screen 3. When the extrusion block 10 moves, it can The limit block 601 is driven to move. When the limit block 601 moves, the outer shell 603 can be driven to move along the surface of the inner shell 7. When the limit block 601 moves, the extrusion force generated on the spring 602 can cause the spring 602 to undergo elastic deformation. When the limit block 601 is disengaged from the limit groove 13 and completely moves to the inner cavity of the device groove 4, the filter 3 can be taken out from the inner cavity of the purification body 1, and then the replaced filter 3 can be installed by pulling the control block 5. At this time, the filter 3 of the air purifier can be replaced more stably.

[0036] To sum up: the air purification device with a replacement structure, by setting the limiting device 6, the limiting block 601, the spring 602, the outer shell 603 and the limiting groove 13 for coordinated use, solves the problem that the existing air purifier usually includes components such as an air filter, an activated carbon adsorption layer, an ultraviolet sterilization lamp, etc. The filter will accumulate a large amount of dust, dirt, bacteria and other impurities. After long-term use, the filter needs to be replaced. If it is not replaced in time, it is easy to lead to a decrease in the purification effect. Usually, the filter is limited to the inner cavity of the purification body by a plastic buckle positioning method. Frequent replacement of the filter is easy to cause the plastic buckle to break. If the plastic buckle is broken, the replacement of the filter will be unstable. However, the existing air purifier does not have a component for stable replacement of the filter.
