Upper serpentine strips are provided above the lower serpentine strips, and top rods connected to the upper serpentine strips are provided above the bottom rods. A serpentine channel is formed between the upper and lower serpentine strips, and a clamping channel is formed between the top rods and the bottom rods. The air filter element body is disposed inside the frame. The two sides of the air filter element body in the length direction are inserted into the serpentine channel and clamped and fixed by the upper and lower serpentine strips. The two ends of the air filter element body in the width direction are inserted into the clamping channel and clamped and fixed by the top rods and bottom rods.

[0006] As a preferred technical solution, the middle of the upper serpentine strip is recessed to form a pressure groove, and the two sides of the frame are recessed to form an installation groove, which is directly opposite the pressure groove. The installation groove is provided with a fixing groove, and the bottom of the fixing groove is embedded with a bearing. The inner ring of the bearing is installed with a shaft, one end of which extends to the outside and is fitted with a pressure plate. One side of the pressure plate is set to abut against the pressure groove.

[0007] As a preferred technical solution, a spring is installed on the section of the shaft located inside the fixed groove.

[0019] The embodiments of this utility model are described in detail below. 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 steps in all methods or processes disclosed herein, 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 detachable antibacterial air filter, comprising a frame 2 and an air filter body 1. Lower serpentine strips 10 are installed on both sides of the length direction inside the frame 2, and bottom rods 12 connected to the lower serpentine strips 10 are installed on both sides of the width direction inside the frame 2. Upper serpentine strips 3 are provided above each of the lower serpentine strips 10, and top rods 11 connected to the upper serpentine strips 3 are provided above each of the bottom rods 12. A serpentine channel 13 is formed between the upper serpentine strips 3 and the lower serpentine strips 10, and a clamping channel is formed between the top rods 11 and the bottom rods 12. The air filter body 1 is disposed inside the frame 2. The two sides of the air filter body 1 in the length direction are inserted into the serpentine channel 13 and clamped and fixed by the upper serpentine strips 3 and the lower serpentine strips 10. The two ends of the air filter body 1 in the width direction are inserted into the clamping channel and clamped and fixed by the top rods 11 and the bottom rods 12.

[0023] In this embodiment, the middle of the upper serpentine strip 3 is recessed to form a pressure groove 7, and the two sides of the frame 2 are recessed to form an installation groove 8 opposite to the pressure groove 7. The installation groove 8 is provided with a fixing groove, and a bearing is embedded in the bottom of the fixing groove. A shaft 9 is installed in the inner ring of the bearing. One end of the shaft 9 extends to the outside and is fitted with a pressure plate 5. One side of the pressure plate 5 is in contact with the pressure groove 7.

[0024] In this embodiment, a spring is installed on a section of the shaft 9 located inside the fixed groove. The outer ring of the spring is installed on the inner wall of the fixed groove. A limiting part 6 protrudes from the pressure groove 7 and is set to abut against the pressure plate 5. The spring can provide a torsional force to the shaft and the pressure rod, so that the pressure plate can move automatically to the pressure groove.

[0025] In this embodiment, positioning strips 4 are installed at both ends of the upper serpentine strip 3, and positioning grooves are provided on the inner side of the frame 2 opposite to the positioning strips 4. The positioning strips 4 are inserted into the positioning grooves. The upper serpentine strip can be positioned by the positioning strips and positioning grooves, avoiding tilting and swaying.

[0026] In this embodiment, the shape of the serpentine channel 13 matches the shape of the cross-section of the air filter body 1, thereby enabling the edge of the air filter body to be tightly clamped and sealed.

[0027] In this embodiment, an antibacterial layer is provided on the air filter body 1. The antibacterial coating adopts existing technology, which can be obtained by immersing the air filter body in an antibacterial active material solution and drying it in a blower drying oven. The antibacterial coating can effectively kill germs in the filtered air.

[0028] In this embodiment, the upper surface of the pressure plate 5 is flush with the upper surfaces of the frame 2 and the upper serpentine strip 3.

[0029] During installation, the folded section along the length of the air filter body fits onto the lower serpentine strip. The lower serpentine strip vertically positions the folded section of the air filter body, preventing it from closing or sticking together, allowing air to fully enter the folded gaps. The two ends of the air filter body along the width can rest on the base rod.

[0030] After the above is completed, the upper serpentine strip presses onto the upper surface of the air filter body and combines with the lower serpentine strip to form a serpentine channel, thereby fully clamping and sealing the fold, preventing loosening, and eliminating the need for glue. The top rod clamps and seals the edges of the air filter body in the width direction.

[0031] After being moved into place, the pressure plate automatically rotates into the pressure groove by the twisting of the spring, thereby limiting the upper serpentine bar and the push rod;

[0032] Conversely, during disassembly, the pressure plate can rotate outward around the shaft. After the pressure plate is removed from the pressure groove, the upper serpentine strip can be directly removed. Once the upper serpentine strip is no longer obstructing the air filter, the air filter body can be directly removed from the frame, making it convenient to replace.

[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.
