Through this arrangement, the first mounting shell 52, the second mounting shell 53 and the filter plate 561 can be sealed by the tight fit between the tensioning frame 563 and the first mounting shell 52 or the second mounting shell 53, so that air can pass through the filter plate 561 as much as possible, thereby improving the filtering effect. At the same time, the elastic balls 566 push the rectangular frame 564, and the rectangular frame 564 can make the tensioning sleeve and the first mounting shell 52 or the second mounting shell 53 tightly fit. The contact surface is smoother, which improves the sealing effect. At the same time, the first mounting shell 52, the second mounting shell 53 and the baffle frame 3 can be sealed under the action of the sealing frame 541, so that the air can be filtered through the filter plate 561 as much as possible to improve the filtering effect. At the same time, the sealing frame 541 is installed in the baffle frame 3 under the action of the fixing plate 545 and the clamping ball 546 provided in the rubber frame 542.

[0041] like Figure 14-18As shown, the clamping device 6 includes a fixed shell 61, an elastic expansion plate 62 and a guide body 64. The fixed shell 61 has longitudinally arranged elastic expansion plates 62 rotatably connected on both sides thereof. The two elastic expansion plates 62 are respectively arranged on the left and right sides of the housing 1. A fixing groove 63 is provided at one end of the elastic expansion plate 62 away from the fixed shell 61. The elastic expansion plate 62 is arranged on the outside of the clamping rod 2 through the fixed groove 63. The fixed shell 61 has evenly distributed connecting plates 51 fixedly connected at the rear. The fixed shell 61 has guide bodies 64 fixedly connected at the top and bottom thereof. The guide bodies 64 include rectangular blocks 641, sliding The movable plate 643, the slide bar 644, the spring 645, the rotating plate 646, the connecting strip 647, the guide plate 648 and the rotating shaft 649, the rectangular block 641 is provided with mounting grooves 642 on both the front and rear sides, the front end of the mounting groove 642 provided by the rectangular block 641 is fixedly connected with the slide bar 644, the sliding plate 643 is provided on the outside of the slide bar 644, the sliding plate 643 is provided with a spring 645, the spring 645 is arranged on the outside of the slide bar 644, one side of the sliding plate 643 is rotatably connected with the rotating plate 646, the side of the rotating plate 646 away from the sliding plate 643 is rotatably connected with the connecting strip 647, and the connecting strip 647 away from the rotating plate 64 A guide plate 648 is fixedly connected to one side of the plate 6, a rotating shaft 649 is arranged in the guide plate 648, and the rectangular block 641 is fixedly connected to the rotating shaft 649 through the installation groove 642 provided therein, and one side of the guide plate 648 is arranged in the installation groove 642 provided in the rectangular block 641, and a card slot 7 is provided on one side of the card plate 4, and the rectangular block 641 and the card plate 4 are arranged together in the card slot 7 provided in the card plate 4. Through this arrangement, the connecting plate 51 can be driven to move through the fixed shell 61, thereby driving the sealing body 54 to be installed and disassembled, and at the same time, under the action of the guide plate 648, the rectangular block 641 can enter the card accurately and quickly. The guide plate 648 is in the card slot 7 provided on the card plate 4. When the guide plate 648 enters the card slot 7 provided on the card plate 4, the guide plate 648 rotates on the outside of the rotating shaft 649, and at the same time pushes the rotating plate 646 to rotate on the side of the sliding plate 643. The sliding plate 643 slides on the outside of the sliding rod 644. At this time, the spring 645 is compressed, and the guide plate 648 can be pushed by the elastic force of the spring 645, so that the rotation of the guide plate 648 is more stable, which is convenient for guiding the rectangular block 641 and facilitating the installation of the fixed shell 61. Finally, the fixed groove 63 provided by the elastic telescopic plate 62 is clamped on the outside of the clamping rod 2 to complete the installation of the fixed shell 61.

[0042] Working process: When using this air filter, first, install this air filter in a suitable position. After the air enters the shell 1 through the fixed shell 61, it is filtered by the filter plate 561 arranged in the shell 1. After multiple filtrations, the air is discharged to achieve multi-layer filtration of the air. After that, after long-term use, the air filter is removed, and then the elastic telescopic plate 62 is rotated. The elastic telescopic plate 62 drives the elastic telescopic plate 62 to extend under the action of the fixed groove 63 and the clamping rod 2. Then the telescopic plate is removed from the clamping rod 2, and then the fixed shell 61 is directly removed from the outside of the shell 1. At this time, the fixed shell 61 drives the first mounting shell 52 and the second mounting shell 53 to move through the connecting plate 51, and the first mounting shell 52 gradually passes through the clamping frame 543 until the second mounting shell 53 is removed. A mounting shell 52 is taken out from the shell body 1, and then the two push plates 555 are pushed. The push plates 555 drive the clamping strip 553 to slide in the slide groove 552 provided in the mounting plate 551 through the connecting block 554. After the clamping strip 553 leaves the positioning groove 58 provided in the first mounting shell 52 or the second mounting shell 53, the mounting plate 551 is moved forward. At this time, the mounting plate 551 drives the supporting block 557 to move until the supporting block 557 leaves the limiting groove 59 provided in the first mounting shell 52 or the second mounting shell 53, and then the mounting plate 551 is taken out from the first mounting shell 52 or the second mounting shell 53. At this time, the filter plate 561 can be taken out from the first mounting shell 52 or the second mounting shell 53, and then the new filter plate 561 can be put into the first mounting shell 52 or the second mounting shell. The mounting plate 551 is placed in the first mounting shell 52 or the second mounting shell 53, and then the support block 557 provided on the mounting plate 551 is inserted into the limiting groove 59 provided in the first mounting shell 52 or the second mounting shell 53, and then the card strip 553 is driven into the mounting frame by the push plate 555 and the connecting block 554. After the mounting plate 551 is placed in the first mounting shell 52 or the second mounting shell 53, the push plate 555 is pushed in the opposite direction, and the push plate 555 drives the card strip 553 to gradually enter the positioning groove 58 provided in the first mounting shell 52 or the second mounting shell 53 through the card block. At this time, under the action of the inclined surface provided by the card strip 553, the card strip 553 drives the mounting plate 551 to move toward the filter plate 561. At this time, the mounting plate 551 pushes the elastic frame 556 to fit closely with the filter plate 561, and at the same time, the filter plate 561 pushes the sealing frame 541 The sealing frame 541 is tightly fitted with the first mounting shell 52 or the second mounting shell 53, and the sealing frame 541 is deformed. At the same time, the two rectangular frames 564 in the sealing frame 541 push the elastic ball 566 to deform. The elastic force of the elastic ball 566 causes the rectangular frame 564 to push the sealing frame 541 to fit tightly with the first mounting shell 52 or the second mounting shell 53, so that the sealing frame 541 fits more tightly with the first mounting shell 52 or the second mounting shell 53. Then, the sealing body 54 is placed in the housing 1. At this time, the first mounting shell 52 passes through the two baffle frames 3. During the movement of the fixed shell 61, the guide plate 648 first enters the card slot 7 opened by the card plate 4, and the rectangular block 641 is guided by the guide plate 648 until the rectangular frame 564 gradually enters the card slot 7 opened by the card plate 4.At this time, the guide plate 648 is pushed to rotate outside the rotating shaft 649 by the action of the card plate 4. The guide plate 648 pushes the rotating plate 646 to rotate at one end of the sliding plate 643 through the connecting strip 647. The sliding plate 643 slides outside the sliding rod 644 until the fixed shell 61 contacts the shell 1. At this time, the elastic expansion plate 62 is rotated from top to bottom. The elastic expansion plate 62 is stuck on the outside of the card rod 2 through the fixed groove 63. At the same time, the first installation shell 52 or the second installation shell 53 pushes the sealing frame 541 to deform, thereby realizing the sealing between the first installation shell 52, the second installation shell 53 and the blocking frame 3, so that the air can stably pass through the multiple filter plates 561 for filtering.
