[0036] Reference Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the axial view of the filtering device provided in the embodiments of this application. Figure 2 This is a schematic diagram of the filter element of the filtration device provided in the embodiments of this application being installed in the folded assembly. Figure 3 for Figure 2A partial enlarged view at point A. This embodiment discloses a filtration device, which includes a frame 1, a folding assembly 2, and a filter element 3. The folding assembly 2 is disposed within the frame 1 and includes multiple first limiting members 21 and multiple second limiting members 22. The multiple first limiting members 21 and multiple second limiting members 22 are respectively connected to form multiple limiting parts 23. The multiple limiting parts 23 are distributed along the height extension direction of the frame 1, and each limiting part 23 is provided with a limiting cavity 230. The filter element 3 passes through each limiting cavity 230 to limit the filter element 3 through each limiting part 23, and to form a pleated structure for the filter element 3, which increases the filtration area, improves the filtration efficiency, and reduces the resistance when air flows through the filter element, thereby increasing the airflow. The length extension direction of the frame 1 is the X direction in the figure, the width extension direction of the frame 1 is the Y direction in the figure, and the height extension direction of the frame 1 is the Z direction in the figure.

[0037] In this embodiment, the filter element 3 is made of polyester synthetic fiber material. Polyester synthetic fiber material has good stretchability and folding resistance, as well as good high temperature and low temperature resistance, which enables the filtration device to adapt to different environments, ensuring the applicability of the filtration device. In addition, the filter element 3 is not easily damaged, reducing costs.

[0038] In this embodiment, multiple first limiting members 21 and multiple second limiting members 22 are connected to form multiple limiting parts 23. Each limiting part 23 is provided with a limiting cavity 230. When installing the filter element 3, the filter element 3 is inserted into each limiting cavity 230. The filter element 3 is limited by each limiting part 23 to fix the filter element 3. When disassembling the filter element 3, the filter element 3 can be pulled out from each limiting cavity 230 to complete the disassembly of the filter element 3. The installation and disassembly are simple and convenient, which facilitates the maintenance of the filtration device and eliminates the need to replace the entire filtration device, thus reducing costs.

[0039] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 4 This is a schematic diagram of the structure of the first limiting member of the filtering device provided in the embodiments of this application. Figure 5 for Figure 4A magnified view of section B. The first limiting member 21 and the second limiting member 22 are movably connected, allowing the distance between each limiting part 23 to change, enabling the folding assembly 2 to switch between a folded state and an unfolded state. This allows the folding assembly 2 to adjust its height according to the frame 1 of different heights, ensuring the applicability of the folding assembly 2. Specifically, each limiting part 23 includes a first limiting member 21 and a second limiting member 22. The first limiting member 21 includes a first body 210, a first bending part 211, and a first connecting part 212. The first bending part 211 is connected to both ends of the first body 210, and the first connecting part 212 is connected to the end of the first bending part 211. The second limiting member 22 includes a second body 220, a second bending part 221, and a second connecting part 222. The second bending part 221 is connected to both ends of the second body 220, and the second connecting part 222 is connected to the end of the second bending part 221. The first connecting part 212 is fitted onto the second bending part 221. In two adjacent limiting parts 23, the second connecting part 222 of the second limiting member 22 of one limiting part 23 is sleeved on the first bending part 211 of the first limiting member 21 of the other limiting part 23.

[0040] In this embodiment, the first connecting portion 212 and the second connecting portion 222 are annular structures, and the first bending portion 211 and the second bending portion 221 are columnar structures, which facilitates the sliding of the first connecting portion 212 at the first bending portion 211 and the sliding of the second connecting portion 222 at the second bending portion 221. It can be understood that in other embodiments, the first connecting portion 212, the second connecting portion 222, the first bending portion 211 and the second bending portion 221 may also be other structures.

[0041] Reference Figure 6 and Figure 7 As shown, Figure 6 This is a side cross-sectional view of the filtering device provided in the embodiments of this application. Figure 7 for Figure 6 A partial enlarged view at point C. Frame 1 includes a cover plate 11, a base plate 12, and support members 13. The filter device also includes fasteners 4. Two support members 13 are provided, respectively disposed on both sides of the base plate 12, and the shape of each support member 13 corresponds to the shape of the folding assembly 2, so as to support the folding assembly 2 through the support members 13. The support members 13 and the base plate 12 form a receiving portion 14. A first limiting member 21 and a second limiting member 22 are disposed in the receiving portion 14, so as to limit the first limiting member 21 and the second limiting member 22 through the support members 13 and the base plate 12. The cover plate 11 covers the base plate 12. The cover plate 11 has a first connecting hole, and the base plate 12 has a second connecting hole. Fasteners 4 pass through the first connecting hole and the second connecting hole, and fix the cover plate 11 and the base plate 12 through the fasteners 4, so as to limit the folding assembly 2 in the width extension direction of the frame 1.

[0042] In this embodiment, the fastener 4 is a bolt, which ensures the stability of the connection between the cover plate 11 and the base plate 12. It can be understood that in other embodiments, the cover plate 11 and the base plate 12 may also be connected in other ways, such as a snap-fit ​​connection.

[0043] Reference Figure 7 As shown, the first bending portion 211 and the second bending portion 221 form a first fold portion 24, and the support member 13 includes a second fold portion 130. The first fold portion 24 and the second fold portion 130 are configured to cooperate, wherein the angle α of the second fold portion 130 is in the range of 15° to 75°.

[0044] In this embodiment, the angle α of the second pleated portion 130 can be 15°, 25°, 35°, 45°, 55°, 65°, or 75°. Preferably, the angle α of the second pleated portion 130 is 60°, which reduces the resistance of the airflow filter element 3 and ensures a good filtration effect.

[0045] When installing the filter device, the filter element 3 is inserted into each limiting cavity 230. The filter element 3 is limited by each first limiting member 21 and each second limiting member 22. Then, the folding assembly 2 and the filter element 3 are placed together in reverse on the support member 13, so that the first fold 24 formed between the first limiting member 21 and the second limiting member 22 cooperates with the second fold 130 of the support member 13, thereby pressing the entire filter element 3 into a folded shape. Finally, the cover plate 11 is placed on the bottom plate 12 and the folding assembly 2 is pressed tightly. The cover plate 11 is connected to the bottom plate 12 by the fastener 4 to complete the installation of the filter device.

[0046] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
