[0017] Compared with the prior art, the present application has at least the following beneficial effects:

[0018] In the above scheme, by setting the guide frame, the filter plate, the two material fixing frames, the two material storage barrels, the extrusion plate, the fixed frame, the extrusion wheel, the stop block, the supporting mechanism, the sealing gasket, the jack, the vertical rod, the top block, the limiting plate, the pressing plate, the jacking rod and the first compression spring, the vertical rod can be turned vertically, and then the vertical rod is moved downward, so that the top block pushes the frontmost filter plate downward until it is pushed into the air inlet pipe, thereby filtering the air entering the air inlet pipe. At this time, the filter plate is supported by the two push plates to prevent it from falling. When the filter plate in the air inlet pipe needs to be cleaned after being used for a period of time, the frontmost filter plate in the upper material storage barrel is extruded downward by the vertical rod, thereby pushing the filter plate in the air inlet pipe downward into the air outlet pipe, so that the new filter plate is placed in the air inlet pipe again. Then, the air in the house is discharged through the air outlet pipe. At this time, the filter plate in the air outlet pipe is blown clean, thereby achieving the effect of automatic cleaning. By repeating the above steps, the filter plates in the material storage barrels can be used in order and automatically cleaned in order. When the filter plate in the air outlet pipe is extruded downward by the filter plate above, it will extrude the two extrusion wheels below and slide into the lower material storage barrel. Then, the pressing plate is pressed, and the jacking rod pushes the filter plate in the lower material storage barrel away from the two extrusion wheels, so that the subsequent filter plate can normally slide into the material storage barrel. When the filter plate in the upper material storage barrel is used up, the two material storage barrels can be removed and exchanged to facilitate the replacement and use of the filter plates, thereby effectively improving the practicality of the fresh air system.

[0019] By setting the anti-rotation mechanism and the cleaning mechanism, the air blown out by the air outlet pipe can drive the fan blade to rotate, further driving the brush plate to rotate through the rotating shaft, thereby cleaning the filter plate in the air outlet pipe, further improving the cleaning effect of the filter plate. To prevent the fan blade from continuously rotating the rotating shaft, the positioning frame is moved towards the limiting block by the elastic force of the second tension spring when the rotating rod is rotated and the abutting plate is moved out of the limiting hole. The positioning frame is in contact with the limiting block, thereby limiting the limiting block to prevent further rotation. When the fan blade needs to rotate normally, the abutting plate is pulled out of the limiting hole, and the rotating rod is rotated, thereby abutting the abutting plate against the U-shaped frame to ensure the normal separation of the positioning frame and the limiting block. At the same time, the sealing plate also seals the inner wall of the air outlet pipe to prevent air from being discharged from the fixed shaft.

[0020] By setting the limiting assembly, the positioning effect of the extrusion plate can be achieved, when the lower storage cylinder is normally used, only need to manually push the extrusion plate to the deepest part in the storage cylinder, the two positioning rods can be used to limit the two ends of the extrusion plate, so as to avoid the extrusion plate from sliding randomly, so as to facilitate the subsequent storage of the cleaned filter plate, when the extrusion plate needs to be normally used, only need to pull the two positioning rods outward, the extrusion plate can be moved by the elastic force of the first tension spring.

[0021] By setting the clamping plate, the clamping groove and the second compression spring, the storage cylinder can be quickly installed in the fixed material frame, only need to insert the storage cylinder into the fixed material frame, the front end of the clamping plate can be clamped into the clamping groove, so as to avoid the storage cylinder from falling, when the storage cylinder needs to be removed from the fixed material frame, only need to press the rear end of the two clamping plates, then pull it out, the use is more convenient, the operation is more flexible.

When the upper filter plate 8 extrudes the two extrusion wheels 15, the two extrusion wheels 15 will move towards the two sides to ensure that the filter plate 8 slides down smoothly.

[0049] As shown in Figure 5 and Figure 7 , the back of each fixed frame 4 is provided with two opposite second through slots 36 and two opposite first through slots 35, the first through slot 35 is matched with the fixed frame 14 and the extrusion wheel 15, and the second through slot 36 is matched with the extension plate 13. The inner wall of each first through slot 35 and second through slot 36 is fixedly connected with a sealing piece on one side. Through the setting of the above structure, it can be ensured that after the storage cylinder 5 is inserted into the fixed frame 4, the dust outside is prevented from entering the fixed frame 4, so as to ensure the cleaning effect of the filter plate 8 in the storage cylinder 5. When the storage cylinder 5 is inserted into the fixed frame 4, the corresponding sealing piece will be pushed open. After the corresponding parts are away from the sealing piece, the sealing piece can be restored to its original state.

[0050] As shown in Figure 4 and Figure 8 , the inner wall of each storage cylinder 5 is fixedly connected with a positioning block 28, and the positioning block 28 is arranged on the right side of the limiting assembly. The positioning block 28 is two, and the two positioning blocks 28 are arranged oppositely. Through the setting of the positioning block 28, the filter plate 8 in the storage cylinder 5 is limited, so that the extrusion plate 27 normally pushes the filter plate 8 after the positioning of the extrusion plate 27 is released.

[0051] As shown in Figure 4 and Figure 8 , the inner wall of each storage cylinder 5 is provided with a side frame 11 on both sides, the inner wall of each side frame 11 is fixedly connected with a first guide rod 26, and the two ends of the extrusion plate 27 are sleeved on the two first guide rods 26. A first tension spring 25 is sleeved on each first guide rod 26, and the two ends of the first tension spring 25 are fixedly connected to the inner wall of the side frame 11 and the surface of the extrusion plate 27 respectively. Through the setting of the above structure, it can be ensured that the two ends of the extrusion plate 27 slide in the side frame 11, and the filter plate 8 does not contact the first tension spring 25 and the first guide rod 26 when it slides in the storage cylinder 5. Therefore, the extrusion plate 27 can normally push the filter plate 8 to move.

[0052] As shown in Figure 8As shown, the limiting assembly includes two positioning rods 10. One end of each positioning rod 10 passes through the two side frames 11 and is inserted into the end of the extrusion plate 27. A third tension spring 38 is fixedly connected to the middle of each positioning rod 10, and the other end of the third tension spring 38 is fixedly connected to the surface of the side frame 11. With the setting of the limiting mechanism, when the storage cylinder 5 below is in normal use, the extrusion plate 27 can be manually pushed to the deepest part of the storage cylinder 5, and the two positioning rods 10 can be used to limit the two ends of the extrusion plate 27, thereby preventing the extrusion plate 27 from sliding at will, so as to facilitate the subsequent storage of the cleaned filter plate 8. When the extrusion plate 27 needs to be used normally, the two positioning rods 10 can be pulled outward, and the extrusion plate 27 can be moved by the elastic force of the first tension spring 25.

[0053] like Figures 5 to 8 As shown, each side frame 11 has a snap-fit ​​plate 9 hinged to its surface. The front end of the snap-fit ​​plate 9 is inclined. Each material frame 4 has a slot 39 on both sides. One end of the snap-fit ​​plate 9 is snapped into the slot 39. The other end of each snap-fit ​​plate 9 is fixedly connected to a second compression spring 37. One end of the second compression spring 37 is fixedly connected to the surface of the side frame 11. With the above structure, the material storage cylinder 5 can be quickly installed into the material frame 4. Simply insert the material storage cylinder 5 into the material frame 4, and the front end of the snap-fit ​​plate 9 will automatically snap into the slot 39, thus preventing the material storage cylinder 5 from falling out. When it is necessary to remove the material storage cylinder 5 from the material frame 4, simply press the rear end of the two snap-fit ​​plates 9 and then pull them out. It is more convenient to use and more flexible to operate.

[0054] The working principle provided by the present application is that first, the clean filter plates 8 are sequentially stored in the upper storage cylinder 5, and the positioning of the upper extrusion plate 27 is released, so that the extrusion plate 27 can normally push the filter plates 8 in the storage cylinder 5 to move forward, and the frontmost filter plate 8 is limited and blocked by the stop block 41 to avoid falling off, then the user turns the vertical rod 61 into a vertical state, and then moves the vertical rod 61 downward, so that the top block 62 pushes the frontmost filter plate 8 downward, and the frontmost filter plate 8 is pushed into the air inlet pipe 1, so that the air entering the air inlet pipe 1 is filtered, at this time, the filter plate 8 is supported by the two push plates 18 to avoid falling off, when the filter plate 8 in the air inlet pipe 1 needs to be cleaned after being used for a period of time, the frontmost filter plate 8 in the upper storage cylinder 5 is extruded downward by the vertical rod 61, and then the filter plate 8 in the air inlet pipe 1 is pushed downward into the air outlet pipe 2, so that the new filter plate 8 is placed in the air inlet pipe 1 again, and then the air in the air outlet pipe 2 is used to exhaust the air in the room, at this time, the filter plate 8 in the air outlet pipe 2 is blown dust, which has the effect of automatic cleaning, and the limiting of the limiting block 19 is released, so that the air in the air outlet pipe 2 blows the fan blade 20, which further drives the rotating shaft 29 to rotate the brush plate 24, so that the front of the filter plate 8 is cleaned to ensure cleaning, then the rotating rod 23 is rotated, the abutting plate 48 is rotated and moved out of the limiting hole 49, and the positioning frame 31 is moved toward the limiting block 19 under the elastic force of the second tension spring 33, and then the positioning frame 31 is in contact with the limiting block 19, so that the limiting block 19 is limited, and the rotation of the brush plate 24 is prevented, so that the surface of the filter plate 8 is prevented from being abraded, the above steps are repeated, the filter plate 8 in the storage cylinder 5 is sequentially used, and the filter plate 8 can be sequentially and automatically cleaned, when the filter plate 8 in the air outlet pipe 2 is extruded downward by the filter plate 8 above, the two extrusion wheels 15 below are extruded and moved, and then fall into the lower storage cylinder 5, then the pressing plate 71 is pressed, the top rod 72 pushes the filter plate 8 in the lower storage cylinder 5 away from the two extrusion wheels 15, so that the subsequent filter plate 8 can normally fall into the storage cylinder 5, when the filter plate 8 in the upper storage cylinder 5 is used up, the two storage cylinders 5 are only needed to be removed and exchanged, so that the filter plate 8 can be replaced and used, and the practicability of the fresh air system is effectively improved.
