[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1 Please see Figure 1-5 An air filter with convenient filter material replacement includes a filter box 1, an adjustment assembly 3, and a quick-release assembly 2. The filter box 1 is connected to the adjustment assembly 3, and the adjustment assembly 3 is connected to the quick-release assembly 2. The quick-release assembly 2 is used to quickly install and remove the filter layer 213. The adjustment assembly 3 is used to adjust the distance between adjacent filter layers 213 to optimize airflow distribution and filtration efficiency.

[0021] The filter box 1 includes a main body 101 and a cover 102, wherein the cover 102 is hinged to the top surface of the main body 101.

[0022] The quick-release assembly 2 includes a quick-release box 201, a spring cavity 202, a hook cavity 203, a first through cavity 204, a pull cavity 205, and a second through cavity 206. The quick-release box 201 has the spring cavity 202, hook cavity 203, first through cavity 204, pull cavity 205, and second through cavity 206 sequentially opened inside, and the adjacent cavities are interconnected.

[0023] The quick-release assembly 2 also includes a push spring 207, a hook block 208, a connecting plate 209, a pull block 210, a hook rod 211, a pull rod 212, and a filter layer 213. The push spring 207 is fixedly connected to the side of the spring cavity 202, and the hook block 208 is fixedly connected to the other end of the push spring 207. The hook rod 211 is slidably arranged in the first through cavity 204, and the upper end of the hook rod 211 extends to the outside of the first through cavity 204. The filter layer 213 is fixedly connected to the side of the hook rod 211. The bottom surface of the hook block 208 abuts against the hook rod 211. The pull block 210 is slidably arranged in the pull cavity 205, and the pull block 210 and the hook block 208 are fixedly connected by the connecting plate 209. The pull rod 212 is slidably arranged in the second through cavity 206, and the pull rod 212 abuts against the pull block 210. The upper end of the pull rod 212 extends to the outside of the second through cavity 206.

[0024] When the filter layer 213 needs to be replaced, open the cover 102, lift the lever 212, and the lever 212 slides upward in the second cavity 206 and pushes the pull block 210 through the abutment surface. The pull block 210 drives the hook block 208 through the connecting plate 209 to compress the push spring 207, causing the hook block 208 to separate from the hook rod 211. At this time, the hook rod 211 and the filter layer 213 on the side can be pulled out directly upward. When installing the new filter layer 213, insert the hook rod 211 into the first cavity 204, push the lever 212 downward, push the spring 207 to reset, and the hook block 208 abuts against the hook rod 211 again to complete the fixation.

[0025] Example 2 This embodiment adds the following improvements to Embodiment 1: The adjustable distance component 3 includes a sliding rod 301, a sliding plate 302, a driving cylinder 303, and a scissor telescopic component 304. The sliding rod 301, which is arranged horizontally, is fixedly connected inside the main housing 101. Several sets of evenly distributed sliding plates 302 are slidably connected to the sliding rod 301. The sliding plates 302 are fixedly connected to the quick-release box 201. The scissor telescopic component 304 is rotatably connected to the side of the quick-release box 201. The driving cylinder 303 is fixedly connected to the inner side of the main housing 101. The output end of the driving cylinder 303 is fixedly connected to one of the sliding plates 302.

[0026] The drive cylinder 303 is activated, and its output end pushes or pulls the connected sliding plate 302, which slides along the sliding rod 301. Under the linkage of the scissor lift telescopic component 304, adjacent quick-release boxes 201 move synchronously, achieving uniform adjustment of the spacing between the filter layers 213. By changing the spacing, the airflow distribution between the filter layers 213 is optimized, avoiding excessively fast or slow local airflow and improving overall filtration efficiency.

[0027] Working principle When the filter layer 213 needs to be replaced, open the cover 102, lift the lever 212, and the lever 212 slides upward in the second cavity 206 and pushes the pull block 210 through the abutment surface. The pull block 210 drives the hook block 208 through the connecting plate 209 to compress the push spring 207, causing the hook block 208 to separate from the hook rod 211. At this time, the hook rod 211 and the filter layer 213 on the side can be pulled out directly upward. When installing the new filter layer 213, insert the hook rod 211 into the first cavity 204, push the lever 212 downward, push the spring 207 to reset, and the hook block 208 abuts against the hook rod 211 again to complete the fixation.

[0028] The drive cylinder 303 is activated, and its output end pushes or pulls the connected sliding plate 302, which slides along the sliding rod 301. Under the linkage of the scissor lift telescopic component 304, adjacent quick-release boxes 201 move synchronously, achieving uniform adjustment of the spacing between the filter layers 213. By changing the spacing, the airflow distribution between the filter layers 213 is optimized, avoiding excessively fast or slow local airflow and improving overall filtration efficiency.
