[0021] Embodiment

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the components of the air purifier rely on elements such as screws and buckles for fixing, and when disassembling, tools are often required, the disassembly process is relatively cumbersome, resulting in a long disassembly time, and when maintaining the air purifier, it is not fast and convenient enough. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides an upper and lower shell structure of an air purifier which is convenient for fixing and disassembling, including a lower shell body 1 and an upper shell body 11. A fixing component is fixedly installed on the outer side of the upper shell body 11. The fixing component includes a first collar 12 and a second collar 13. A cover plate 15 is movably installed at the top end of the lower shell body 1. By rotating the cover plate 15, the cover plate 15 rotates at the top end of the lower shell body 1. At the same time, the cover plate 15 drives a second clamping plate 18 to rotate at the top end of the lower shell body 1. The movement of the second clamping plate 18 presses the bottom end of a limiting block 21. Since the bottom end of the limiting block 21 is convexly designed, the limiting block 21 moves upward under force. Two second clamping plates 18 are fixedly installed at the bottom end of the cover plate 15. A fixing ring 14 is fixedly installed on the surface of the lower shell body 1. Two holes are formed on the surface of the fixing ring 14. At the same time, the two second clamping plates 18 are symmetrically installed at the bottom end of the cover plate 15 and are clamped with the grooves at the top end of the lower shell body 1.

[0024] Two positioning pins 17 are fixedly installed at the bottom end of the upper shell body 11. An insertion plate 23 is fixedly installed at the bottom end of the first collar 12. At least two telescopic rods 22 are fixedly installed at the top end of the second collar 13. Two first clamping plates 16 are fixedly installed at the top end of the lower shell body 1. A limiting block 21 is slidably installed at the bottom end of the first clamping plate 16. A spring rod 19 is fixedly installed at the top end of the limiting block 21. A plurality of grooves are formed on the surface of the second collar 13 and are butt-jointed with the insertion plate 23. By rotating the first collar 12, the first collar 12 drives the second collar 13 and the insertion plate 23 to rotate together. The insertion plate 23 deflects inside the fixing ring 14 to make the insertion plate 23 fit with the card slot. By pulling the upper shell body 11 upward, the upper shell body 11 drives the first collar 12 to move upward. The insertion plate 23 passes through the inside of the fixing ring 14 to disconnect the lower shell body 1 from the upper shell body 11. A plurality of arc-shaped positioning grooves are formed at the top end of the fixing ring 14 and are butt-jointed with the insertion plate 23.

[0025] Working principle:

[0026] First step, by pushing the second sleeve ring 13 upward, the second sleeve ring 13 slides upward at the bottom end of the first sleeve ring 12, reducing the distance between the first sleeve ring 12 and the second sleeve ring 13. The second sleeve ring 13 squeezes the telescopic rod 22 upward, causing the telescopic rod 22 to expand and contract. At the same time, a plurality of grooves are provided on the surface of the second sleeve ring 13, and the grooves fit with the insertion plate 23. The second sleeve ring 13 will slide upward along the surface of the insertion plate 23. The second sleeve ring 13 drives the positioning block at the bottom end to leave the groove at the top end of the fixed ring 14. At this time, by rotating the first sleeve ring 12, the first sleeve ring 12 drives the second sleeve ring 13 and the insertion plate 23 to rotate together. The insertion plate 23 deflects inside the fixed ring 14, making the insertion plate 23 fit with the card slot. By pulling the upper shell body 11 upward, the upper shell body 11 drives the first sleeve ring 12 to move upward. The insertion plate 23 passes through the inside of the fixed ring 14 to disconnect the lower shell body 1 from the upper shell body 11. At the same time, when the upper shell body 11 moves upward, the positioning pin 17 slides inside the cover plate 15, and the positioning pin 17 leaves the inside of the cover plate 15.

[0027] Second step, after removing the upper shell body 11 by rotating the first sleeve ring 12, at the same time, the upper shell body 11 drives the positioning pin 17 to leave the cover plate 15, releasing the fixed state of the cover plate 15. By rotating the cover plate 15, the cover plate 15 rotates at the top end of the lower shell body 1. At the same time, the cover plate 15 drives the second clamping plate 18 to rotate at the top end of the lower shell body 1. The movement of the second clamping plate 18 squeezes the bottom end of the limiting block 21. Since the bottom end of the limiting block 21 is convexly designed, the limiting block 21 moves upward under force, squeezing the spring rod 19, forcing the spring rod 19 to compress, and making the limiting block 21 enter the inside of the first clamping plate 16. By continuing to rotate the cover plate 15, the cover plate 15 drives the second clamping plate 18 to disconnect from the first clamping plate 16. By pulling the cover plate 15 upward, the cover plate 15 leaves the top end of the lower shell body 1. At the same time, the cover plate 15 drives the second clamping plate 18 to move upward and leave the top end of the lower shell body 1, enabling the rapid disassembly and installation of the upper shell body 11 and the cover plate 15, which is convenient for maintenance.

[0028] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
