DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The embodiment of the present application discloses a filter element for air filter. Figure 2 and Figure 3 The air filter element comprises a filter screen 1 and a housing 2 fixedly connected to both sides of the filter screen 1. The filter screen 1 comprises a mounting frame 11 and a filter plate 12; the mounting frame 11 is in a rectangular frame shape; the filter plate 12 is fixedly connected to the mounting frame 11, the filter plate 12 is inclined, and a plurality of filter plates 12 are arranged and evenly spaced; the filter plate 12 is made of non-woven fabric, and a ventilation gap is arranged between two adjacent filter plates 12, so as to filter the passing air.

[0034] The shell 2 is in the shape of a rectangular frame, and the size of the shell 2 is the same as that of the installation frame 11. The shell 2 is a thin paper shell, and the first reinforcing rib 3 and the second reinforcing rib 4 are fixedly connected to the shell 2, and the length direction of the first reinforcing rib 3 is parallel to the length direction of the shell 2; there are three first reinforcing ribs 3, and they are arranged at intervals along the width direction of the shell 2; there are two second reinforcing ribs 4, and the two second reinforcing ribs 4 are arranged crosswise, and the second reinforcing ribs 4 are connected between two opposite corners on the shell 2; therefore, the arrangement of the first reinforcing rib 3 and the second reinforcing rib 4 can improve the strength of the shell 2. The width of the second reinforcing rib 4 is smaller than that of the first reinforcing rib 3, so the material used to make the reinforcing rib can be reduced, which is more economical and helps to reduce costs.

[0035] Furthermore, a connecting piece 5 is fixedly connected between the second reinforcing rib 4 and the corner of the outer shell 2. The connecting piece 5 is triangular in shape, so the provision of the connecting piece 5 increases the strength of the corner of the outer shell 2, making it less likely to break.

[0036] Reference Figure 3 , a frame 6 is fixedly bonded to the side of the outer shell 2 close to the filter 1, and the frame 6 is made of rigid plastic, so the frame 6 can support the outer shell 2, reduce the possibility of deformation of the outer shell 2, and thus ensure the protective effect of the filter 1. A first magnetic member 61 is fixedly connected to the side of the frame 6 away from the outer shell 2, and correspondingly, a placement groove 111 is provided on the edge of the installation frame 11, and the shape of the placement groove 111 is the same as that of the frame 6, and a second magnetic member 1111 is fixedly connected to the bottom wall of the placement groove 111. The magnetic poles of the first magnetic member 61 and the second magnetic member 1111 on the side close to each other are in opposite directions, so after the frame 6 is placed in the placement groove 111, the first magnetic member 61 and the second magnetic member 1111 can be attracted to each other, which helps to improve the stability of the outer shell 2 after installation.

[0037] Reference Figure 3 and Figure 4 , one of the shells 2 is fixedly connected with a first positioning column 7 on the side close to the frame 6, and four first positioning columns 7 are provided and respectively located at the four corners of the shell 2; the other shell 2 is fixedly connected with a second positioning column 8 on the side close to the frame 6, and four second positioning columns 8 are provided and respectively located at the four corners of the shell 2; correspondingly, positioning holes 112 are opened at the four corners of the installation frame 11, and the positioning holes 112 are through holes; therefore, after the installation of the shell 2 is completed, the first positioning column 7 and the second positioning column 8 are respectively inserted at the two ends of the positioning hole 112, so it helps to improve the installation effect of the shell.

[0038] Further, refer to Figure 5The first positioning column 7 is fixedly connected to one end away from the housing 2 with a buckle 721, which is made of plastic and has elasticity; the second positioning column 8 is provided with a slot 81 adapted to the buckle 721 at one end away from the housing 2. After the housings 2 on both sides are installed, the buckle 721 on the first positioning column 7 is engaged with the slot 81 on the second positioning column 8, thereby preventing the first positioning column 7 and the second positioning column 8 from sliding toward the side away from each other, thereby further enhancing the stability of the housing 2 after installation.

[0039] The first positioning column 7 includes a positioning portion 71 and a connecting portion 72. Both the positioning portion 71 and the connecting portion 72 are cylindrical, and the diameter of the positioning portion 71 is larger than the diameter of the connecting portion 72; the positioning portion 71 is fixedly connected to the corner of the housing 2, and the diameter of the positioning portion 71 is the same as the aperture of the positioning hole 112; the connecting portion 72 is fixedly connected to the end of the positioning portion 71 away from the housing 2, the connecting portion 72 and the positioning portion 71 are coaxially arranged, and the buckle 721 is fixedly connected to the end of the connecting portion 72 away from the positioning portion 71. A through hole 21 is provided at the corner of the shell 2, and the through hole 21 is a through hole. The through hole 21 and the positioning portion 71 are coaxially arranged; a receiving groove 711 is coaxially provided at one end of the positioning portion 71 close to the shell 2, and the receiving groove 711 and the through hole 21 are connected; the diameter of the receiving groove 711 and the aperture of the through hole 21 are the same as the diameter of the connecting portion 72, so the connecting portion 72 on one shell 2 can be slid into the receiving groove 711 on another shell 2, so that multiple shells 2 can be stacked and stacked conveniently.

[0040] Furthermore, a rounded corner 712 is provided at one end of the positioning portion 71 away from the housing 2 , thereby facilitating the positioning portion 71 to slide into the positioning hole 112 .

[0041] The structure of the second positioning column 8 is substantially the same as that of the first positioning column 7 . The slot 81 is disposed at an end of the second positioning column 8 away from the housing, thereby facilitating the buckle 721 to be inserted into the slot 81 .

[0042] The implementation principle of a filter element for an air filter in the embodiment of the present application is as follows: place two outer shells 2 on both sides of the filter screen 1, align the first positioning column 7 with the second positioning column 8 with the positioning hole 112, and then move the two outer shells 2 to the side close to each other, so that the first positioning column 7 and the second positioning column 8 both slide into the positioning hole 112, and then make the buckle 721 on the first positioning column 7 snap into the slot 81 on the second positioning column 8, so as to fix the two outer shells 2; during the process, the frame 6 can slide into the placement slot 111, and then the first magnetic part 61 and the second magnetic part 1111 are attracted to each other, which can further improve the stability of the outer shell 2 after installation. Since the widths of the first reinforcing rib 3 and the second reinforcing rib 4 set on the outer shell 2 are different, consumables can be reduced while ensuring the connection strength.

[0043] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
