[0030] 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.

[0031] This utility model provides a technical solution: a rotating locking structure for an air purifier base, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 The air purifier body 1 and the base assembly 2 located at the bottom of the air purifier body 1, wherein the base assembly 2 is composed of the upper base fixing member 3, the lower base cover 4 and the lower base fixing member 5.

[0032] The base cover 4 is located at the bottom of the base fixing member 3, and the base fixing member 5 is located at the bottom of the base cover 4. Wheels 7 are connected to the bottom of the base fixing member 3 around the perimeter.

[0033] The rotating component 6 is located on the top of the base fixing member 5, and the rotating component 6 consists of a rotating handle 8 and a rotating block 9, with the rotating handle 8 located on the upper surface of the rotating block 9.

[0034] The first height-lowering structure 17, the second height-lowering structure 18, and the third height-lowering structure 19 are respectively installed on the upper base fixing member 3, the lower base fixing member 5, and the lower base cover 4. By operating the rotating component 6, the lower base fixing member 5 and the upper base fixing member 3 are driven to rotate. The first height-lowering structure 17 on the upper base fixing member 3 works in conjunction with the third height-lowering structure 19 on the lower base cover 4 to adjust the height of the base assembly 2 to achieve the effect of base rotation locking. When the rotating component 6 is operated, the base assembly 2 is lowered to complete the fixing, raising the height of the base assembly 2 to hide the wheels 7, which can fix the air purifier and prevent it from being easily moved. When the rotating component 6 is operated in the opposite direction, the base assembly 2 is raised, lowering the height of the base assembly 2, and the wheels 7 are exposed. The main body of the purifier 1 is moved as a whole by the rolling of the wheels 7. Since there is no need to add a braking mechanism to the wheels 7, it is not only convenient to use, but also hides the distance between the wheels 7 and the ground, thus avoiding affecting the appearance.

[0035] Please see Figure 5 , Figure 6A limiting cylinder 10 is evenly installed at the bottom of the rotating handle 8, and side connecting holes 12 are evenly opened on the front side of the limiting cylinder 10. The rotating handle 8 is connected to the corresponding structure through the limiting cylinder 10 and the side connecting holes 12. A side connecting groove 11 is evenly opened at the rear end of the inner wall of the limiting cylinder 10, and a compression spring 13 is added to the inner cavity of the side connecting groove 11. The compression spring 13 can drive the connecting structure to move within the side connecting groove 11, and the stability of the compression spring 13 within the limiting cylinder 10 can be ensured by the side connecting groove 11. A fixed insert 14 is connected to the front end of each compression spring 13, and the front end of each fixed insert 14 is inserted into the corresponding side connecting hole 12. The compression spring 13 drives the fixed insert 14 to move outward along the side connecting hole 12 within the side connecting groove 11, and can apply pressure to the fixed insert 14, so that the fixed insert 14 drives the compression spring 13 to compress within the side connecting groove 11. The upper surface of the rotating block 9 is uniformly provided with limiting holes 15, and the limiting holes 15 correspond in position and shape to the limiting cylinder 10. When the rotating handle 8 is connected to the rotating block 9, the rotating handle 8 drives the limiting cylinder 10 to be inserted into the limiting hole 15 of the rotating block 9 for connection. When the rotating assembly 6 is severely worn or damaged after long-term use, the rotating handle 8 or the rotating block 9 can be replaced separately, thereby reducing the cost of use. The front side of the rotating block 9 is uniformly provided with fixing holes 16, and the fixing holes 16 communicate with the limiting holes 15. The fixing holes 16 correspond in position and shape to the fixing posts 14. When the rotating handle 8 drives the limiting cylinder 10 to be inserted into the limiting hole 15 of the rotating block 9, the compression spring 13 drives the fixed insertion post 14 to move outward along the side connecting hole 12 in the side connecting groove 11, so that the fixed insertion post 14 is inserted into the fixed insertion hole 16. The fixed insertion post 14 can be squeezed inward along the fixed insertion hole 16 from the outside of the rotating block 9, so that the fixed insertion post 14 retracts into the limiting cylinder 10 and squeezes the compression spring 13. The limiting cylinder 10 can be pulled out from the limiting hole 15 of the rotating block 9 by rotating the handle 8, which not only facilitates disassembly and assembly operations, but also ensures connection stability.

[0036] This solution: By operating the rotating component 6, the lower base fixing part 5 and the upper base fixing part 3 are driven to rotate. The upper base fixing part 3 has a first height difference structure 17, which works in conjunction with the third height difference structure 19 of the lower base cover 4 to adjust the height of the base component 2, achieving the effect of base rotation locking. When the rotating component 6 is operated, the base component 2 is lowered to complete the fixing, raising the height of the base component 2 to hide the wheels 7, thus fixing the air purifier and preventing it from being easily moved; when the rotating component 6 is operated in reverse, the base component 2 is raised, lowering the height of the base component 2. With wheel 7 in the exposed state, the purifier body 1 moves as a whole by rolling wheel 7. When rotating handle 8 drives the limiting cylinder 10 to be inserted into the limiting hole 15 of rotating block 9, compression spring 13 drives fixed plug 14 to move outward along side connecting hole 12 in side connecting groove 11, so that fixed plug 14 is inserted into fixed plug hole 16. Fixed plug 14 can be squeezed inward along fixed plug hole 16 outside rotating block 9, so that fixed plug 14 retracts into limiting cylinder 10 and squeezes compression spring 13. Limiting cylinder 10 can be pulled out from limiting hole 15 of rotating block 9 by rotating handle 8.
