Three filter plates 2 of different grades are installed inside the shell 1, and the filter plate 2 is installed between an upper fixing plate 8 and a lower fixing plate 9. A pull ring is fixedly connected to the top of the upper fixing plate 8, and a connecting component is arranged between the lower fixing plate 9 and the connecting plate 7. A transverse plate 3 is fixedly connected to opposite sides of the shell 1, and a rotating shaft 4 is rotatably connected to the middle part of one side of the transverse plate 3, a rotating fan 5 is fixedly connected to one side of the rotating shaft 4, and a rotating shaft 4 is coaxially connected to the other side of the transverse plate 3. Servo motor 6, connecting assembly includes a pair of arc plates 10 fixedly connected to the bottom end of the lower fixing plate 9, a pair of arc plates 10 are provided with grooves 11 on opposite sides, a return spring 12 is fixedly connected to one side of the groove 11, a short column 13 is fixedly connected to one side of the return spring 12, a trapezoidal block 14 is fixedly connected to one side of the short column 13, a receiving groove 15 is provided in the middle of the top of the connecting plate 7, a fixed column 16 is fixedly connected to the bottom end of the receiving groove 15, a slide groove 17 is provided on the outer side of the middle of the fixed column 16, a slider 18 is slidably connected to the outer side of the slide groove 17, a snap ring 19 that conflicts with the trapezoidal block 14 is fixedly connected to the outer side of the slider 18, the top of the fixed column 16 and the slider 18 are two mirror-symmetrical cones 20, and the inclined surface of the cone 20 at the top of the fixed column 16 is aligned with the trapezoidal block 1 4, the angles of the inclined surfaces are consistent with each other, an opening 21 is provided at the top of the connecting plate 7 and is connected to the receiving groove 15, a pair of compression springs 22 for contacting the bottom end of the lower fixing plate 9 are fixedly connected to the bottom end of the opening 21 and are located on both sides of the receiving groove 15, three groups of wind shields are fixedly connected to the opposite sides of the shell 1, and each group of wind shields is located on both sides of the filter plate 2, one side of the wind shield and the two sides of the opening 21 are provided with limiting grooves 23 for sliding, both sides of the filter plate 2 are fixedly connected with limiting strips 24 corresponding thereto, and the relatively far sides of the opening 21 are provided with limiting grooves 23 identical to those of the wind shields. At present, when replacing the filter plate 2, most of the combined clean fresh air air conditioning units on the market need to disassemble the shell 1 first, and then replace the internal filter plate 2, which is a process. The replacement process of the filter plate 2 is relatively cumbersome, which not only reduces the replacement efficiency, but also makes it easy for the connection of the air-conditioning unit housing 1 to become loose and unstable due to multiple disassembly, posing a safety hazard. When replacing the filter plate 2, stop the servo motor 6 to drive the rotating fan 5 to rotate, and press the upper fixing plate 8 to allow the trapezoidal column at the bottom end of the lower fixing plate 9 to move downward from the bottom end of the cone 20. Because the short column 13 on one side of the trapezoidal block 14 is connected with the return spring 12, when the inclined surface of the trapezoidal block 14 contacts the slider 18, an extrusion force is generated, causing the return spring 12 to retract and get stuck with the snap ring 19 on the outside of the slider 18. At this time, pull the pull ring upward, and the trapezoidal block 14 drives the slider 18 to follow the upward movement on the slide groove 17. When the slider 18 moves to the bottom end of the cone 20,When the pulling force is greater than the friction force between the snap rings 19, and under the pressure of the return spring 12, the trapezoidal block 14, after being separated from the slider 18, coincides with the inclined surface of the cone 20 and slides out at a fast speed, so that the filter plate 2 can be pulled out of the installation groove. When the filter plate 2 needs to be installed, the limiting strips 24 on both sides of the filter plate 2 are first aligned with the limiting grooves 23 on one side of the windshield plate, and then the limiting strips 24 on both sides of the filter plate 2 slide in the limiting grooves 23 while pushing downward. At the same time, the compression spring 22 on the bottom end of the opening exerts an upward elastic force on the filter plate 2, so that the trapezoidal block 14 is steadily fixed at the bottom end of the cone 20, and the fixation is completed. The filter plate 2 can be replaced by pressing and pushing and pulling. Compared with the disassembly and replacement in the market, it reduces the labor intensity, improves the work efficiency, and relatively prolongs the service life of the equipment.

[0023] Working principle: When replacing the filter plate 2, stop the servo motor 6 to drive the rotating fan 5 to rotate, and press the upper fixing plate 8 to allow the trapezoidal column at the bottom of the lower fixing plate 9 to move downward from the bottom of the conical body 20. Because the short column 13 on one side of the trapezoidal block 14 is connected with the return spring 12, when the inclined surface of the trapezoidal block 14 contacts the slider 18, an extrusion force is generated, causing the return spring 12 to shrink inward and get stuck with the retaining ring 19 on the outside of the slider 18. At this time, the pull ring is pulled upward, and the trapezoidal block 14 drives the slider 18 to follow the upward movement on the slide groove 17. When the slider 18 moves to the bottom of the conical body 20, when the pulling force is greater than the friction between the retaining rings 19, and at the same time, under the extrusion of the return spring 12, the trapezoidal block 14 is separated from the slider 18 and moves with the conical body 20 at the same speed. The inclined surfaces of the body 20 coincide with each other and slide out, so that the filter plate 2 can be pulled out from the installation groove. When the filter plate 2 needs to be installed, first align the limiting strips 24 on both sides of the filter plate 2 with the limiting grooves 23 on one side of the wind shield, and then push the filter plate 2 downward until the trapezoidal block 14 slides to the bottom end of the conical body 20. While pushing downward, the limiting strips 24 on both sides of the filter plate 2 slide in the limiting grooves 23. At the same time, the compression spring 22 on the bottom end of the opening exerts an upward elastic force on the filter plate 2, so that the trapezoidal block 14 is steadily fixed at the bottom end of the conical body 20, and the fixation is completed. The filter plate 2 can be replaced by pressing and pushing and pulling. Compared with disassembly and replacement in the market, it reduces labor intensity, improves work efficiency, and relatively extends the service life of the equipment.
