[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a filter element installation mechanism of an air purification device includes a fixing ring 1. An installation ring 3 is detachably connected inside the fixing ring 1. A filter bag 4 is fixedly connected to the bottom end of the installation ring 3. The fixing ring 1 and the installation ring 3 are provided with a clamping mechanism. An installation mechanism for limiting the installation ring 3 is installed at the bottom of the fixing ring 1; the clamping mechanism includes two openings 2 formed in the top plate of the fixing ring 1 and recessed downward to the inner wall of the fixing ring 1. The clamping mechanism further includes two sliders 8 integrally formed on the outer periphery of the installation ring 3. The cross-section of the slider 8 is equal to the cross-section of the opening 2; a starting limiting block 5 and an ending limiting block 6 are fixedly connected to the inner wall of the fixing ring 1. A sliding groove 7 for the slider 8 to rotate is formed between the starting limiting block 5 and the ending limiting block 6. One surface of the starting limiting block 5 is aligned with one surface of the opening 2 in the vertical direction.

[0020] In this embodiment: First, when installing the filter bag 4, align the installation ring 3 at the top of the filter bag 4 with the inner periphery of the top plate of the fixing ring 1, and at the same time align the slider 8 with the opening 2. Then press down the installation ring 3. The installation ring 3 drives the slider 8 to pass through the opening 2 until the bottom end of the installation ring 3 contacts the top end of the bottom plate of the fixing ring 1. Then rotate the installation ring 3. The installation ring 3 drives the slider 8 to move along the inner wall of the sliding groove 7 until the slider 8 is clamped with the installation mechanism, and the installation of the filter bag 4 can be completed. Moreover, the installed filter bag 4 is not easy to slide, and the installation effect is stable.

[0021] Please refer to Figure 3 , the installation mechanism includes a fixing frame 10 fixedly connected to the bottom plate of the fixing ring 1. A circular hole is formed in the horizontal plate portion of the fixing frame 10. A limiting column 11 is slidably connected up and down on the inner wall of the circular hole. The top of the limiting column 11 is in a hemispherical structure. The installation mechanism further includes a limiting disc 12 integrally formed on the outer periphery of the limiting column 11 and located below the bottom plate of the fixing ring 1. A spring 13 is fixedly connected between the bottom end of the limiting disc 12 and the top end of the horizontal plate portion of the fixing frame 10. The spring 13 is sleeved on the limiting column 11.

[0022] In this embodiment: During the rotation of the installation ring 3, the installation ring 3 can drive the slider 8 to rotate. The slider 8 moves towards the installation mechanism until the slider 8 contacts the hemispherical end of the limiting column 11. At this time, the slider 8 contacts the top hemispherical end of the limiting column 11. At this time, the top of the limiting column 11 is forced to drive the limiting column 11 to move downward. The downward moving limiting column 11 drives the limiting disc 12 to move downward. The downward moving limiting disc 12 squeezes the spring 13 until the hemispherical end at the top of the limiting column 11 completely moves below the slider 8. When the slider 8 drives the hemispherical groove 9 to rotate to the directly above the limiting column 11, at this time the spring 13 resets, and the spring 13 pushes the limiting disc 12 to move upward. The upward moving limiting disc 12 can push the top of the limiting column 11 to snap into the hemispherical groove 9, completing the fixation of the slider 8, and thus completing the fixation of the filter bag 4;

[0023] Conversely, when disassembling the filter bag 4, by rotating the mounting ring 3 in the reverse direction, the disassembly of the filter bag 4 can be achieved, realizing the technical effect of convenient installation and disassembly.

[0024] Please refer particularly to Figure 3 , a hemispherical groove 9 is formed at the bottom end of the slider 8 and is adapted to the hemispherical structure at the top of the limiting post 11. A circular groove for the up-and-down sliding of the limiting post 11 is formed on the bottom plate of the fixing ring 1, and the diameter of the circular groove is smaller than the diameter of the limiting disc 12.

[0025] In this embodiment: the setting of the hemispherical groove 9 can accommodate the hemispherical structure at the top of the limiting post 11, thereby realizing the installation of the filter bag 4, and the formation of the circular groove facilitates the up-and-down sliding of the limiting post 11.

[0026] Please refer particularly to Figure 3 , the inner diameter of the top plate of the fixing ring 1 is larger than the inner diameter of the bottom plate of the fixing ring 1, and the bottom plate of the fixing ring 1 is used to support the bottom end of the mounting ring 3.

[0027] In this embodiment: the bottom plate of the fixing ring 1 can support the top of the bottom plate of the fixing ring 1, facilitating the installation of the mounting ring 3.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
