DETAILED DESCRIPTION

[0025] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0026] The utility model provides a kind of portable filter screen assembly of air purifier convenient to fold as Figures 1-5 As shown in the drawing, comprising:

[0027] Two groups of filter screen 1 and support frame 2 for clamping and fixing filter screen 1 are used;

[0028] Support frame 2 includes fixed seat 21 and right-angle folding frame 22, both ends of right-angle folding frame 22 are hinged to adjacent two groups of fixed seat 21 by hinge, filter screen 1 is located between right-angle folding frame 22, and limiting frame 3 is arranged at the corner away from fixed seat 21 of right-angle folding frame 22, for fixing two groups of right-angle folding frame 22 in upper and lower positions, to prevent filter screen 1 from shaking;

[0029] By the design of support frame 2 structure, right-angle folding frame 22 and fixed seat 21 are movably connected by hinge, it is convenient to fold right-angle folding frame 22 and fixed seat 21, reduce the volume of support frame 2 as a whole, not only convenient to carry and store, but also when replacing filter screen assembly, it is convenient to fold filter screen assembly and then unfold in the inside of purifier, improve the portability of air purifier maintenance.

[0030] As shown in the drawing, comprising: Figure 2

[0031] ​The top view of the fixed seat 21 is isosceles trapezoidal, and the included angle between the two oblique sides and the two parallel sides of the isosceles trapezoid is 45 degrees. By limiting the shape of the fixed seat 21, it is ensured that the right-angle folding frame 22 and the fixed seat 21 can form a rectangular support frame 2 after being unfolded, thereby maintaining the stability of the structure of the support frame 2.

[0032] Further, as shown in Figure 2

[0033] The right-angle folding frame 22 is provided with a clamping groove 4 at the right angle, and the limiting frame 3 is clamped in the clamping groove 4. Through the arrangement of the clamping groove 4, it is convenient to clamp the limiting frame 3 on the right-angle folding frame 22, and the shape of the support frame 2 is maintained.

[0034] Preferably, as shown in Figure 3

[0035] The opposite side of the right-angle folding frame 22 is provided with a limiting groove 6 and a limiting strip 5, respectively. The limiting strip 5 extends into the limiting groove 6. Through the cooperation of the limiting strip 5 and the limiting groove 6, it is convenient to clamp and fix the filter screen 1, so as to ensure that the filter screen 1 is stably clamped and fixed, thereby playing a filtering role.

[0036] It is worth noting that, as shown in Figures 3-4

[0037] The top and bottom of the inner cavity of the limiting frame 3 are provided with cavities, and the cavities are fixed with supporting springs 7. The movable end of the supporting spring 7 is fixed with a limiting piece 8. The right-angle folding frame 22 is provided with a limiting hole 9 for clamping the limiting piece 8. Through the support of the supporting spring 7 to the limiting piece 8, the limiting piece 8 penetrates to the outside of the limiting frame 3 and is clamped with the limiting hole 9 on the right-angle folding frame 22, preventing the limiting frame 3 from separating from the right-angle folding frame 22, so that the two groups of right-angle folding frames 22 cannot clamp and fix the filter screen 1.

[0038] Further, as shown in Figure 5

[0039] The fixed seat 21 includes two groups of supporting seats 211. The top of the supporting seat 211 is hingedly connected to each other. By limiting the structure of the fixed seat 21, it is convenient to fold the fixed seat 21 again when the support frame 2 is rectangular, thereby further reducing the volume of the folded filter screen assembly.

[0040] In addition, as shown in Figure 5

[0041] The outer side of the supporting seat 211 is provided with a clamping groove 10, and the clamping groove 10 is clamped with a connecting piece 11. Through the clamping groove 10, the connecting piece 11 is fixed and limited, so as to conveniently fix and connect the two groups of supporting seats 211 through the connecting piece 11, thereby maintaining the stability of the structure of the fixed seat 21.

[0042] ​​​​​In the embodiment, as shown in Figure 2

[0043] The two right-angle edges of the right-angle folding frame 22 are of the same length, the upper and lower ends of the fixing seat 21 of the supporting frame 2 are provided in a protruding manner, the structure of the right-angle folding frame 22 is limited to ensure that the right-angle folding frame 22 can be stably folded, and meanwhile, the upper and lower ends of the supporting frame 2 are designed in a protruding manner to facilitate the clamping of the supporting frame 2 with the inside of the air purifier, thereby ensuring the stability of the filter screen assembly.

[0044] In specific use, the limiting frame 3 is removed from the right-angle folding frame 22, then the right-angle folding frame 22 is folded along the hinge, the right-angle folding frame 22 is turned over to the upper and lower ends of the fixing seat 21, the four right angles of the supporting frame 2 are folded, the volume of the supporting frame 2 is reduced, when the supporting frame 2 is rectangular, the volume of the filter screen assembly is still large after the right-angle folding frame 22 is folded, the connecting piece 11 can be removed from the clamping groove 10, and the fixing seat 21 is folded over with the supporting seat 211.

[0045] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.​
