[0022] The following is a further description of the specific implementation methods of the present invention in conjunction with the accompanying drawings. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

The "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0024] See also Figure 1 、 Figure 6 A plate-type air filter that is easy to clean and replace includes a frame 1 and a filter cloth 5. The frame 1 and the filter cloth 5 are both prior arts. The frame 1 is square-shaped, and the filter cloth 5 is usually installed in the frame 1 in three shapes, namely, wavy, V-pleated and flat.

[0025] See also Figure 1 、 Figure 2 、 Figure 3In one embodiment, the filter cloth 5 is secured to the upper and lower sides of the frame 1, respectively, with each clamping assembly comprising two clamping plates 7, one front and one rear. A chute 2 is formed on both the upper and lower sides of the inner frame of the frame 1 along the front-to-back direction. The front and rear ends of the chute 2 are connected to the front and rear ends of the frame 1, respectively. A rigid thin plate 3 is welded to the middle section of the chute 2, dividing the chute 2 into two sections. The thickness of the thin plate 3 is less than the thickness of the filter cloth 5. Sliders 8 are welded or bonded to the clamping plates 7. The sliders 8 are slidably connected to the chute 2 along the front-to-back direction. The slider 8 on the front side is slidably connected to the front chute 2, while the slider 8 on the rear side is slidably connected to the rear chute 2. When both sliders 8 slide to the thin plate 3, the clamping plates 7 on the front and rear sides secure (clamp) the filter cloth 5 in the middle. The thickness of the thin plate 3 determines the distance between the two clamping plates 7 during clamping.

[0026] See also Figure 3 A magnet 9 is fixed in the slider 8 on the front side, and an iron block 10 is fixed in the slider 8 on the other side. The sliders 8 on both sides are pressed against the thin plate 3 by the attraction between the magnet 9 and the iron block 10, and can be separated by manpower and slide out along the slide groove 2.

[0027] See also Figure 1 、 Figure 4 、 Figure 5 In one embodiment, a pressure plate 4 is hingedly provided on each of the left and right sides of the frame 1, with the rotation axis of each plate being vertical. A torsion spring 6 is provided between the pressure plate 4 and the frame 1, with the central axis of the torsion spring 6 being vertical. One end of the torsion spring 6 is fixedly connected to the pressure plate 4 by welding, and the other end is fixedly connected to the frame 1, so that the pressure plate 4 can press the edges of the filter cloth 5 against the frame 1 on both sides. This arrangement further improves the fixing effect of the filter cloth 5.

[0028] See also Figure 2 、 Figure 5 In one embodiment, the cross-section of the chute 2 is convex, and the slider 8 is also convex, with its size adapted to the chute 2. This arrangement allows the slider 8 to be more stably limited in the up, down, left, and right directions, resulting in a more stable effect.

[0029] See also Figure 1 In one embodiment, a plurality of slide grooves 2 are arranged along the left-right direction on the upper and lower sides of the inner frame of the frame 1, and the slider 8 is slidably arranged in each of the slide grooves 2, and there is one thin plate 3 in each of the slide grooves 2. This arrangement can further improve the structural stability.

[0030] In one embodiment, the height of the clamping plate 7 is between 2.5 cm and 5 cm. This setting can achieve a stable clamping effect by keeping the height of the clamping plate 7 within this range, and will not cover the filter cloth 5 in large quantities to affect the filtering effect.

[0031] See also Figure 1 In one embodiment, the clamping plate 7 is a long rectangular plate for adapting to the filter cloth 5 installed in a flat shape.

[0032] See also Figure 4 In one embodiment, the clamping plate 7 is a wavy plate, and the wavy shapes of the clamping plates 7 on the upper and lower sides and the front and rear sides correspond to each other, so as to adapt to the filter cloth 5 installed in a wavy shape.

[0033] See also Figure 6 In one embodiment, the splint 7 is a V-shaped pleated plate, and the V-shaped pleats of the splint 7 on the upper and lower sides and the front and rear sides correspond to each other, and are used to adapt to the filter cloth 5 installed in a V-shaped pleated shape.
