[0021] 1. This application utilizes the cooperative arrangement of structures such as a sliding groove, a return rod, and a first spring. During use, the filter element body is first inserted into the mounting slot, bringing the return plate close to the electrical control cabinet body. Then, the first spring is compressed by sliding the slider, bringing the return rod closer to the return plate and the slot. Afterward, the slider is released, causing the first spring to spring back, pulling the return rod and locking it into the slot, thus installing and fixing the filter element body. This minimizes the need to open the electrical control cabinet when replacing the filter element, preventing direct external replacement and reducing work efficiency.

[0022] 2. After installing the filter element body, first pull the push-pull rod to compress the second spring, move the insert rod into the cavity, and then insert the insert blocks into the slide grooves respectively. By releasing the push-pull rod, the second spring will rebound, which can push the insert rod into the insertion hole, connect the insert block with the slider, prevent the insert block from falling out of the slide groove, and install and fix the louver cover. While covering the installation components, it can also block some dust and improve the service life of the filter element body. Attached Figure Description
