In order to solve the above problems, the present application provides an air purifier to solve the problem of high transportation and packaging costs of the existing vertical air purifier due to large volume.

[0029] In some embodiments, as shown in Figures 1-5 An air purifier is provided, comprising,

[0030] An upper housing 1 is provided with an air inlet 11 and an air outlet 12, the air inlet 11 is provided with an air inlet net 13, and the air outlet 12 is provided with an air outlet net;

[0031] A lower housing 2 comprises a top shell 21, a side plate 22, a bottom shell 23 and a base 24, the top shell 21 is connected with the upper housing 1, one end of the side plate 22 is connected with the top shell 21, the other end of the side plate 22 is connected with one end of the bottom shell 23, the other end of the bottom shell 23 is connected with the base 24, a plurality of air inlet holes 221 are arranged on the side plate 22, the side plate 22 is a flexible member, and the cross-sectional area of the lower housing 2 gradually decreases along the axial direction of the lower housing 2;

[0032] A folding filter assembly 3 is connected to the base 24 at one end and connected to the air inlet net 13 at the other end;

[0033] The side plate 22 can be bent to move the base 24 towards the top shell 21 when pressure is applied to the base 24 in the direction of the top shell 21.

[0034] The air purifier of the present application, since the side plate 22 is flexible, when pressure is applied to the base 24 in the direction of the top shell 21, i.e. the base 24 is pressed, the side plate 22 can be bent, so that the top shell 21 and the base 24 are close to each other, driving the folding filter assembly 3 to fold together, the lower shell 2 is folded and compressed as a whole, the overall height of the air purifier is reduced, space is saved, and packaging and transportation costs are reduced. And since the cross-sectional area of the lower shell 2 gradually decreases along the axial direction of the lower shell 2, the base 24 can be accommodated in the space formed by the top shell 21 and the side plate 22 during movement together with the bent side plate 22, or the top shell 21 can be accommodated in the space formed by the base 24 and the side plate 22 together with the bent side plate 22. There is no need for additional locking, and the position of the top shell 21 or the base 24 is fixed by using the elasticity of the bent side plate 22, so that the lower shell 2 remains in a folded and compressed state.

[0035] In some embodiments, as shown in Figure 3 and Figure 4 the cross-sectional area of the lower shell 2 gradually decreases in the direction from the top shell 21 to the base 24. When pressure is applied to the base 24 in the direction of the top shell 21, the side plate 22 can be bent to move the base 24 in the direction of the top shell 21. After the side plate 22 is bent, the inner wall of the side plate 22 close to the top shell 21 fits the inner wall of the side plate 22 close to the base 24. Because the cross-sectional area of the lower shell 2 gradually decreases, the base 24 and the side plate 22 close to the base 24 can be retracted into the side plate 22 close to the top shell 21. At this point, the lower shell 2 is folded and compressed, and the overall height of the air purifier is reduced.

[0036] In some embodiments, the cross-sectional area of the lower shell 2 gradually increases in the direction from the top shell 21 to the base 24. When pressure is applied to the base 24 in the direction of the top shell 21, the side plate 22 can be bent to move the base 24 in the direction of the top shell 21. After the side plate 22 is bent, the outer wall of the side plate 22 close to the top shell 21 fits the outer wall of the side plate 22 close to the base 24. Because the cross-sectional area of the lower shell 2 gradually decreases, the top shell 21 and the side plate 22 close to the top shell 21 can be retracted into the side plate 22 close to the base 24. At this point, the lower shell 2 is folded and compressed, and the overall height of the air purifier is reduced.

[0037] In some embodiments, the side plate 22 is a thermoplastic elastomer. The thermoplastic elastomer can be one of thermoplastic polyester (TPEE), styrene-based thermoplastic elastomer (TPS), thermoplastic polyurethane (TPU), and thermoplastic rubber (TPR).

[0038] In some embodiments, the lower shell 2 is made of a thermoplastic elastomer as a whole.

[0039] In some embodiments, a telescopic rod (not shown) is arranged in the lower housing 2, one end of the telescopic rod is connected with the base 24, and the other end is connected with the upper housing 1. The telescopic rod can provide support for the lower housing 2 and enhance the structural stability of the air purifier as a whole. When the lower housing 2 is folded and compressed, the telescopic rod can be retracted along with the lower housing 2.

[0040] In some embodiments, the top shell 21 is a plastic part, the bottom shell 23 is a plastic part, and the base 24 is a plastic part. The plastic part can be made of one of polypropylene (PP), polystyrene (PS), and acrylonitrile-butadiene-styrene copolymer (ABS), which is not limited herein.

[0041] In some embodiments, a first locking part (not shown) is arranged on the top shell 21, and a second locking part (not shown) is arranged on the base 24. The first locking part can cooperate with the second locking part. When the lower housing 2 is folded and compressed, the first locking part and the second locking part can be connected to prevent the elasticity of the side plate 22 from resetting the top shell 21 or the base 24, thereby ensuring that the lower housing 2 maintains the compressed and folded state.

[0042] In some embodiments, the first locking part is a buckle strap with a positioning hole, and the second locking part is a protruding column on the base 24. The protruding column can be inserted into the positioning hole to complete the locking of the top shell 21 and the base 24 in the folded and compressed state.

[0043] In some embodiments, as shown in Figures 1-5 , the lower housing 2 is in the shape of a circular truncated cone, and the cross-sectional area of the lower housing 2 gradually decreases from the top shell 21 to the base 24.

[0044] In some embodiments, the lower housing 2 is in the shape of a regular truncated prism (not shown), and the cross-sectional area of the lower housing 2 gradually decreases from the top shell 21 to the base 24.

[0045] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 5 , the folding filter assembly 3 includes an upper connecting part 31, a lower connecting part 32, and a folding filter screen 33.

This facilitates the disassembly and installation of the folding filter assembly 3 and facilitates the user to clean or replace the folding filter assembly 3.

[0046] In some embodiments, the folding filter screen 33 is an air filter core in the shape of an axially continuous zigzag folding.

[0047] In some embodiments, the upper connecting piece 31 is snap connected with the air inlet net 13, and the lower connecting piece 32 is snap connected with the base 24.

[0048] In some embodiments, as shown in Figure 3 The air purifier further comprises a fan 4, which comprises an impeller 41 and a driving motor 42, the driving motor 42 is connected with the upper shell 1, the output end of the driving motor 42 is connected with the impeller 41, and the impeller 41 is located at the side of the upper shell 1 close to the air inlet 11. In operation, the fan 4 is started, external air enters the lower shell 2 from the air inlet hole 221 of the side plate 22, then enters the folding filter assembly 3 for filtration, the filtered air enters the upper shell 1 through the air inlet net 13, and is finally sent out from the air outlet 12 of the upper shell 1.

[0049] In some embodiments, as shown in Figure 2 and Figure 3 The base 24 is provided with a hand pulling part 241. When the folding and compressed state of the lower shell 2 is to be released, the user can pull the hand pulling part 241 to move the base 24 away from the top shell 21, so that the lower shell 2 is reset and the air purifier returns to the upright state.

[0050] In some embodiments, as shown in Figure 2 and Figure 3 The side of the base 24 away from the top shell 21 is provided with a groove 242, and the handle part is located in the groove 242. By arranging the handle part in the groove 242, the space of the base 24 is fully utilized.

[0051] In some embodiments, the upper shell 1 and the lower shell 2 are snap connected, and the upper shell 1 and the lower shell 2 can also be screw connected, which is not limited herein.
