[0017] 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.
[0018] Please see Figures 1-5 In this embodiment of the present invention, an installation structure for a folded filter element includes an installation frame 1 and an installation top cover 2 snapped onto the top of the installation frame 1. The inner sides of the installation frame 1 and the installation top cover 2 are provided with limiting mechanisms for limiting the filter element 4. The installation frame 1 and the installation top cover 2 are connected by a fixing mechanism. The inner side of the installation top cover 2 is integrally formed with a downwardly protruding clamping cavity 10. There is a stop plate 9 between the installation top cover 2 and the clamping cavity 10. The width of the stop plate 9 matches the width of the side plate of the installation top cover 2.
[0019] In this embodiment: First, when installing the filter element 4, the filter element 4 is laid flat on the top of the mounting frame 1. Then, a tool (such as a card) is used to press down on the top of the filter element 4. During the pressing process, the filter element 4 bends along the top of the lower half of the limiting mechanism, forming a wavy pleated state. Then, the mounting top cover 2 is pressed down. The cavity 10 between the mounting top cover 2 and the abutment plate 9 is aligned with the end plate of the mounting frame 1. Then, it is pressed down. The pressing mounting top cover 2 drives the upper half of the limiting mechanism to squeeze and limit the top edge of the filter element 4, thus limiting the installation of the filter element 4 and keeping it in a wavy pleated structure. At the same time, during the pressing process of the mounting top cover 2, the mounting top cover 2 drives the upper half of the fixing mechanism to engage with the lower half of the fixing mechanism. After the mounting top cover 2 is fully connected, the upper and lower parts of the fixing mechanism are engaged and locked.
[0020] Please refer to this carefully. Figure 1 and Figure 2 The fixing mechanism includes docking blocks 5 integrally formed at the four corners of the outer wall of the mounting frame 1, and a downward protruding deformation vertical plate 8 integrally formed at the four corners of the bottom end of the mounting top cover 2. An outwardly inclined abutment plate 9 is integrally formed on one side of the bottom end of the deformation vertical plate 8. The docking blocks 5 have through holes 7 for the deformation vertical plate 8 and the abutment plate 9 to pass through.
[0021] In this embodiment: during the downward movement of the top cover 2, the deformation vertical plate 8 driven by the top cover 2 moves downward synchronously. The deformation vertical plate 8 drives the abutment 9 to contact and press against the edge of the through hole 7. At this time, the abutment 9 is forced to deform the deformation vertical plate 8. The abutment 9 then enters the interior of the through hole 7. As the top cover 2 is pressed down, the top cover 2 moves the abutment 9 to below the docking block 5 through the deformation vertical plate 8. At this time, the through hole 7 no longer limits the abutment 9. The deformation vertical plate 8 drives the abutment 9 to reset. The reset abutment 9 abuts against the bottom end of the docking block 5, forming a locking effect.
[0022] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting mechanism includes an upper limit frame 3 integrally formed at both ends of the bottom of the clamping cavity 10 and a lower limit frame 6 integrally formed at both ends of the inner wall of the mounting frame 1, with the upper limit frame 3 located above the lower limit frame 6.
[0023] In this embodiment: when installing the flat filter element 4 using tools, the bottom edge of the pressurized filter element 4 contacts the top of the lower limiting frame 6. At this time, the filter element 4 has a wavy, pleated structure. Then, during the installation of the top cover 2, the installation of the top cover 2 drives the upper limiting frame 3 to squeeze and limit the top edge of the filter element 4. At this time, the filter element 4 can be limited and fixed.
[0024] Please refer to this carefully. Figure 4 and Figure 5 There is a pleated space between the upper limit frame 3 and the lower limit frame 6, and the filter element 4 is installed in the pleated space.
[0025] In this embodiment: the pleated space can restrict the filter element 4 into a pleated structure, increase the filtration interception area, and improve the filtration effect.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
