During operation, when the staff needs to replace the new filter element 102 material, they can first push the filter element 102 backward to make the filter element 102 move backward inside the installation groove 101. When the filter element 102 moves backward, it can drive the installation column 205 and the matching block 207 to move backward. The matching block 207 moves backward and squeezes the limit block 203 and the movable rod 204 outward. At the same time, the limit block 203 squeezes the spring 202, and then the matching block 207 can be slid backward on the surface of the installation column 205, and the side surface of the matching block 207 contacts the end of the limit block 203, so as to break away from the limit of the limit block 203, and then the filter element 102 is pulled out forward, and the filter can be pulled out with the cooperation of the matching block 207 and the inclined surface of the conical block 206.

The matching block 207 moves backward to squeeze the limit block 203 and the movable rod 204 outward. At the same time, the limit block 203 squeezes the spring 202, and then the matching block 207 can be moved backward on the installation column. The surface of the matching block 205 slides backward, and the side surface of the matching block 207 contacts the end of the limit block 203, so that the limit block 203 can be disengaged, and then the filter element 102 is pulled forward, and the filter element 102 can be pulled out from the inside of the installation groove 101 under the cooperation of the matching block 207 and the inclined surface of the conical block 206, so as to complete the removal of the filter element 102. When installing a new filter element 102, the filter element 102 is matched with the installation groove 101 and pushed backward to make the filter element 102 The conical block 206 squeezes the limit block 203 and the spring 202, and when the conical block 206 moves to the rear side of the limit block 203, the limit block 203 can be pushed to move inward at the same time under the action of the rebound force of the spring 202, that is, the conical block 206 can be limited inside the installation groove 101 under the obstruction of the limit block 203, and the filter element 102 can be installed and limited inside the installation groove 101, thereby achieving quick and convenient replacement of the filter element 102. It also brings convenience to the staff. When installing a new filter element 102, the block 303 is adapted to the matching groove 301 at the same time. Then, after the filter element 102 is installed, the filter element 102 is rotated about ninety degrees. The rotation of the filter element 102 will drive the block 303 to slide inside the arc groove 302, and the block 303 can be limited inside the arc groove 302. At the same time, the filter element 102 can be strengthened to prevent the filter element 102 from being displaced inside the installation groove 101.
