Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a multi-layer foldable air filter element, including an air filter element 2 disposed inside a multi-layer frame 1. Each frame 1 is composed of two vertical rods 7 and two horizontal rods 6. The vertical rods 7 and horizontal rods 6 are distributed in a rectangular structure. Each vertical rod 7 and horizontal rod 6 is provided with a groove 12. Multiple grooves 12 on each frame 1 are combined to form a frame-shaped groove. The frame-shaped grooves on the upper and lower frames 1 are connected. A frame 9 is installed on the edge of the air filter element 2. The frame 9 is inserted into the frame-shaped groove and is pressed and fixed inward by the frame 1. Each vertical rod 7 is provided with a wiring groove 11 on its outer side. A steel wire rope 4 for connecting the horizontal rod 6 is provided in the wiring groove 11. One end of each vertical rod 7 is installed on a horizontal rod 6 on one side through a hinge. The other end of each vertical rod 7 is provided with a positioning mechanism connected to the horizontal rod 6 on the other side.

[0023] In this embodiment, the positioning mechanism includes a positioning post 3 and a compression spring. The other end face of the vertical rod 7 is provided with a hidden groove, and the other side of the horizontal rod 6 is provided with a positioning port opposite the hidden groove. One end of the positioning post 3 is inserted into the hidden groove and is fixedly connected to the compression spring. The other end of the compression spring is installed on the inner wall of the hidden groove, and the other end of the positioning post 3 is inserted into the positioning port.

[0024] In this embodiment, the inner wall of the frame-shaped groove is provided with a plurality of positioning holes 13 in a frame-shaped structure, and positioning rods 10 are installed at the edges directly opposite the positioning holes 13, with both ends of the positioning rods 10 inserted into the positioning holes 13.

[0025] In this embodiment, one of the frames 1 is provided with multiple pin holes, and another frame 1 is equipped with a ball head locking pin 5 directly opposite the pin holes. The ball head locking pin 5 passes through the pin holes and locks the two frames 1 together.

[0026] In this embodiment, one of the frames 1 is provided with multiple slots 8, and the other frame 1 is provided with insert plates at the slots 8. The insert plates are inserted into the slots 8. The slots and insert plates can be used to position the multi-layer frame and avoid lateral or longitudinal displacement.

[0027] In this embodiment, the frame 1 is made of engineering plastic, specifically polyamide, which increases its strength, reduces its weight, and gives the frame a certain degree of flexibility. After the vertical bar and the horizontal bar abut each other, the vertical bar can be smoothly rotated out between the horizontal bars by bending, avoiding being stuck. The horizontal bars are connected together by steel wire ropes to prevent them from separating.

[0028] In this embodiment, the cross-section of the air filter element 2 is arranged in a serpentine structure to increase the contact area with the air and better filter impurities in the air.

[0029] During installation, the frame of the air filter is placed into the frame groove of any frame, and the positioning rod on the frame is inserted into the positioning hole to position the edge of the air filter. After another frame is placed on top of the frame, the two frames move inward to press and fix the edge of the air filter to ensure the stability of the installation. The ball head locking pin 5 passes through the pin hole and locks the two frames 1 together.

[0030] After the ball on the ball-head locking pin is pressed inward, the ball-head locking pin can be pulled out of the pin hole to complete the separation of the frame.

[0031] During transportation and storage, the positioning pin can be squeezed to move it out of the positioning port and into the hidden slot. After the positioning pin is no longer blocked, the longitudinal bar can fold inward around the hinge, while the transverse bars are connected together by steel wire rope to prevent separation.

[0032] After folding, one side of the crossbar rotates around the other side of the crossbar, thereby coiling the steel wire rope around the outside of the crossbar and the vertical bar, which can bind them together and prevent the vertical bar from opening on its own. The air filter element can be folded and rolled up due to its flexibility, which greatly reduces its volume and makes it convenient for storage, transportation and carrying.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
