The guide frame is fixedly installed in a target wall. A new HEPA high-efficiency filter core is mounted on the guide frame, and then pushed into the guide frame. The new HEPA high-efficiency filter core is used to push out the HEPA high-efficiency filter core inside the sliding frame, so that the new HEPA high-efficiency filter core is installed in the sliding frame, and then the guide frame is pushed backward so that the guide frame pushes the sliding frame into the guide frame, so that the HEPA high-efficiency filter core can be easily replaced.

[0008] Preferably, the guide frame comprises a first frame body, and a slide groove is provided inside the first frame body to facilitate the extension and retraction of the slide frame.

[0009] Preferably, the sliding frame includes a second frame, a slider and a blocking net, wherein the blocking net is symmetrically fixedly connected to the inner end of the second frame, and the slider is fixedly connected to the outer end of the second frame. When the sliding frame is subjected to a thrust, the second frame is retracted into the first frame, and when the sliding frame is subjected to a pulling force, the second frame is extended along the first frame, so as to facilitate the extension and retraction of the sliding frame.

[0010] Preferably, the sliding frame further comprises a sealing frame, which is fixedly connected to the inside of the second frame body. The sealing frame is used to seal the gap between the HEPA high-efficiency filter element and the air inlet of the second frame body, thereby improving the sealing performance between the HEPA high-efficiency filter element and the sliding frame.

[0011] Preferably, the guide frame includes a spring sheet and an arc rod, one end of the arc rod is fixedly connected to the spring sheet. When the slide frame retracts, the first frame acts inwardly on the spring sheet to retract the guide frame, and when the slide frame extends, the spring sheet is expanded, and the arc rod is used to increase the support strength of the spring sheet.

[0012] Preferably, the correction frame includes a third frame body, and a guide groove is provided at a side end of the third frame body, so as to guide the HEPA high-efficiency filter element into the second frame body, thereby facilitating the correction of the HEPA high-efficiency filter element into a position.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Place the new HEPA high-efficiency filter on the guide frame, and then push it into the guide frame. Use the new HEPA high-efficiency filter to push out the HEPA high-efficiency filter inside the slide frame, so that the new HEPA high-efficiency filter can be installed in the slide frame. Then push the guide frame backwards so that the guide frame pushes the slide frame into the guide frame to facilitate the replacement of the HEPA high-efficiency filter.

[0016] 2. When the sliding frame is pushed, the second frame is retracted into the first frame. When the sliding frame is pulled, the second frame is extended along the first frame, which facilitates the extension and retraction of the sliding frame.

[0017] 3. When the sliding frame retracts, the first frame acts inward on the spring sheet to retract the guide frame. When the sliding frame extends, the spring sheet is expanded, and the arc rod is used to increase the supporting strength of the spring sheet. BRIEF DESCRIPTION OF THE DRAWINGS
