[0028] The present application provides a fixing structure 100 and a filter screen, the fixing structure 100 comprises a support 110 and a plurality of comb teeth 120 arranged in folds corresponding to the filter paper 200 of the filter screen on the support 110. When the fixing structure 100 is installed, the plurality of comb teeth 120 are inserted into the plurality of backfold gaps on one side of the filter paper 200, so that one comb tooth corresponds to one backfold gap, ensuring the stiffness and strength of the filter screen. The fixing structure 100 replaces the adhesive tape and the edge sealing strip during installation of the conventional filter screen, which can reduce the resistance of the filter screen and enhance the stability. The fixing structure 100 has better high temperature resistance than the adhesive tape and the edge sealing strip, which improves the performance of the filter screen. The support 110 is connected with a positioning member 130, and the positioning member 130 is used to position the interval between two fixing structures 100. When the filter paper 200 is installed with a plurality of fixing structures 100, the positioning member 130 ensures the uniform spacing of the plurality of fixing structures 100.

[0029] In combination with Figures 1-2As shown, the fixing structure 100 comprises a support 110, a comb tooth 120 and a positioning piece 130. The support 110 is a strip-shaped plate structure. According to the number of folds of the filter paper 200 and the distance between the adjacent two fold peaks of the filter paper 200, a plurality of comb teeth 120 are arranged on the support 110. The plurality of comb teeth 120 are arranged in a spaced manner along the length direction of the support 110. The comb tooth 120 is a wedge-shaped structure. The end of the comb tooth 120 away from the support 110 is provided with a rounded structure to prevent the comb tooth 120 from piercing the filter paper 200. The support 110 is connected with the positioning piece 130. The positioning piece 130 is used to position the interval between two fixing structures 100. When the filter paper 200 is installed with a plurality of fixing structures 100, the side of the positioning piece 130 of one of the two adjacent fixing structures 100 away from the support 110 is in contact with the positioning piece 130 of the other fixing structure 100, so as to ensure the interval between the two fixing structures 100.

[0030] In the embodiment, the positioning piece 130 is a plate structure. The positioning piece 130 is arranged at the two ends of the length direction of the support 110, Figure 1 、 2 In the embodiment, the support 110 and the positioning piece 130 are arranged perpendicularly. The two positioning pieces 130 are parallel to each other. The two positioning pieces 130 extend towards the same side of the support 110. According to the size of the filter paper 200, the length of the support 110 is designed. After the fixing structure 100 is installed on the filter paper 200, the two positioning pieces 130 are respectively attached to the two side edges of the filter paper 200. The support 110 is connected with one side of the positioning piece 130. The side of the positioning piece 130 facing the comb tooth 120 extends. After the fixing structure 100 is installed on the filter paper 200, the positioning piece 130 is prevented from protruding relative to the filter paper 200, which affects the use of the filter. Figure 2 As shown, the mounting gap 140 is arranged between the positioning piece and the comb tooth 120. The mounting gap 140 is used as the cooperation allowance between the positioning piece and the filter paper 200. According to the use requirement of the filter screen, other components such as a patch can be installed on the two sides of the filter paper 200 to improve the structural strength of the two sides of the filter paper 200 and make the installation of the filter paper more stable.

[0031] As shown, Figure 3 Figure 3 As shown, the fixing structure 100 and the filter paper 200 are shown in the assembly process. A plurality of comb teeth 120 are inserted into a plurality of back-fold gaps on one side of the filter paper 200. The comb tooth 120 can effectively ensure the interval between the two fold peaks of the filter paper 200. The filter paper 200 is not easy to deform and the stiffness of the filter paper 200 is ensured. When the filter paper 200 is installed with a plurality of fixing structures 100, the side of the positioning piece 130 of one of the two adjacent fixing structures 100 away from the support 110 is in contact with the positioning piece 130 of the other fixing structure 100, so as to ensure the interval between the two fixing structures 100.​

[0032] In the scheme, the support 110, the comb teeth 120 and the positioning member 130 can be respectively machined from one of ABS, PP, PET, PA, stainless steel and aluminum alloy, ABS is a plastic that is a terpolymer of acrylonitrile, butadiene and styrene, PP is polypropylene, PET is polyester resin, PA is a plastic formed by nylon or polyamide, and the filter paper 200 can adopt HEPA high-efficiency filter net or carbon cloth.

[0033] The embodiment also provides a filter screen, which is provided with at least one fixing structure 100, and after the fixing structure 100 is used, the installation process of the filter screen is as follows:

[0034] First, the filter paper 200 is folded, and then the length of the support 110, the number of the comb teeth 120 and the interval between adjacent two comb teeth 120 are designed according to the size of the filter paper 200, the number of folds of the filter paper 200 and the distance between adjacent two fold peaks of the filter paper 200. One fixing structure 100 is installed first, and multiple comb teeth 120 are correspondingly inserted into multiple backfold gaps on one side of the filter paper 200, for example, Figure 3 In the scheme, one comb tooth 120 is inserted into one gap, according to the stiffness requirement of the filter screen, multiple fixing structures 100 can be inserted, the spacing between the multiple fixing structures 100 is ensured to be uniform by the positioning member 130, and then the preliminary filter screen, the edge frame, the seal and the packaging are performed to complete the assembly of the filter screen.
