The rotating shaft 7 is sleeved with a limiting ring 13, the limiting ring 13 is coaxially arranged with the rotating shaft 7, the limiting ring 13 is fixedly connected with the rotating shaft 7, the purification pipe 2 is provided with a limiting hole 14, the limiting hole 14 is a circular hole in the pipe wall of the purification pipe 2, the limiting ring 13 is rotationally connected with the purification pipe 2 in the limiting hole 14, and the rotating shaft 7 is limited through the limiting ring 13, so that the rotating shaft 7 can freely rotate on the purification pipe 2.

[0036] The rotating shaft 7 can drive the support seat 6 to rotate, so that the support seat 6 drives the filter plate 3 above the support seat 6 to rotate. The end, away from the support seat 6, of the rotating shaft 7 is fixedly connected with a sprocket 8, a chain 9 is arranged between the two sprockets 8, and the chain 9 is engaged with the two sprockets 8. When one of the rotating shafts 7 rotates, the other rotating shaft 7 can be driven to rotate through the chain 9 and the sprocket 8. One of the rotating shafts 7 is fixedly connected with a hand wheel 10, and the hand wheel 10 drives the rotating shaft 7 to rotate when the hand wheel 10 rotates.

[0037] The hand wheel 10 is rotated to drive one of the rotating shafts 7 to rotate, and the other rotating shaft 7 is driven to rotate through the sprocket 8 and the chain 9, so that the two filter plates 3 are synchronously rotated, and then the two filter plates 3 can be simultaneously rotated by 180° to be turned over, so that the one side of the filter plate 3 on the air inlet side is exchanged with the one side on the air outlet side, so that the two sides of the filter plate 3 can be fully utilized and fully contacted with air.

[0038] Referring to Figure 1 , Figure 4 , Figure 5 The purification pipe 2 is provided with an opening 11 away from the air inlet pipe 1 on the side of the two filter plates 3, and the filter plate 3 can be taken out from the opening 11. The purification pipe 2 is provided with a baffle 12 in the opening 11, the baffle 12 is matched with the opening 11, so that the baffle 12 can seal and shield the opening 11. The baffle 12 is provided with a rubber sealing ring along the outer periphery, which can further improve the sealing performance of the baffle 12.

The baffle plate 12 is provided with a connecting groove 22 matched with the connecting rod 21. When the baffle plate 12 is inserted into the opening 11, the connecting rod 21 is aligned with the connecting groove 22. Rotating the handle 19 to drive the connecting shaft 20 to rotate can make the connecting rod 21 rotate into the connecting groove 22, thereby limiting the baffle plate 12, so that the baffle plate 12 cannot be pulled out of the opening 11 under the blocking of the connecting rod 21.

[0041] Referring to Figure 4 , Figure 6 , Figure 7 , a linkage member is arranged between the baffle plate 12 and the filter plate 3. The linkage member includes a linkage rod 23 fixedly connected to the connecting shaft 20 near the filter plate 3. The linkage rod 23 is parallel to the connecting rod 21. One end of the connecting shaft 20 extends into the filter plate 3. The side of the filter plate 3 close to the connecting shaft 20 is provided with a linkage groove 24. The cross section of the linkage groove 24 is T-shaped. The connecting shaft 20 and the linkage rod 23 can freely rotate in the linkage groove 24.

[0042] When the linkage rod 23 is rotated to a vertical state, it is in the same plane as the filter plate 3 and can drive the filter plate 3 to move when moving, so that the filter plate 3 can be pulled out of the purification pipe 2 by the handle 19. When the linkage rod 23 is rotated with the connecting shaft 20 to be perpendicular to the filter plate 3, the projection of the linkage rod 23 and the connecting shaft 20 on the plane of the filter plate 3 is a straight line at this time, so that the filter plate 3 can be freely rotated with the rotating shaft 7 and the support seat 6 without being blocked by the linkage rod 23 and the connecting shaft 20.

[0043] Referring to Figure 2 , Figure 3 , a limiting member is arranged below the filter plate 3. The limiting member includes a mounting shaft 15 rotatably connected to the purification pipe 2. The mounting shaft 15 is coaxially arranged with the rotating shaft 7. The mounting shaft 15 is located directly below the filter plate 3 and has an upper end fixedly connected to a limiting plate 16. The upper side of the limiting plate 16 is provided with a limiting groove 17 matched with the filter plate 3. The filter plate 3 is further limited by the limiting plate 16 and the limiting groove 17, so that the lower side of the filter plate 3 remains stable. The mounting shaft 15 penetrates the purification pipe 2 and is fixedly connected to a limiting sleeve 18. The limiting sleeve 18 is rotatably connected to the outer wall of the purification pipe 2. The lower end of the mounting shaft 15 is limited by the limiting sleeve 18, so that the mounting shaft 15 is rotatably connected to the purification pipe 2.

[0044] Working principle: in use, through the linkage rod 23 together with the filter plate 3 and baffle 12, so that can be through the handle 19 filter plate 3 and baffle 12 into the purification pipe 2, and the filter plate 3 is installed on the support seat 6, rotating handle 19 can drive the connection shaft 20 rotation, and make the connection shaft 20 on the connecting rod 21 into the connection slot 22, the baffle 12 is installed in the opening 11 on the purification pipe 2, while rotating to linkage rod 23 perpendicular to the filter plate 3, the filter plate 3 lose linkage rod 23 block can be with support seat 6 and rotating shaft 7 freely rotating; located in the air outlet pipe 4 in the air suction fan 5 will be air from the air inlet pipe 1 and from the air outlet pipe 4 blowout, air through the filter plate 3 will be filtered, remove the bacteria and dust in the air, when the filter plate 3 use after a period of time, the air inlet side filter effect decline, can rotate hand wheel 10 drive one of the rotating shaft 7 rotation and through the chain 9 and sprocket 8 drive another rotating shaft 7 rotation, so that two support seat 6 synchronous rotation and drive two filter plate 3 rotate 180 DEG at the same time realize the turnover, and then make the filter plate 3 air inlet side and air outlet side, make full use of the filter plate 3 both sides, improve the utilization efficiency of filter plate 3.

[0045] Example two

[0046] In actual use, the operator found that when the filter plate 3 needs to be cleaned after a period of use, the air inlet side and the air outlet side of the filter plate 3 are adjusted by rotating the hand wheel 10 to make the two rotating shafts 7 rotate 180 DEG synchronously, so as to improve the utilization efficiency of the filter plate 3. However, when the air inlet side and the air outlet side of the filter plate 3 are adjusted, the dust originally adsorbed on the air inlet side will be separated from the filter plate 3 by the suction force of the air suction fan 5 and discharged through the air outlet pipe 4, which causes the device to fail to filter the air entering the air inlet pipe 1. Therefore, in order to solve the above technical problems, the device is improved according to the method described in the embodiment.

[0047] As shown in Figures 8-9 , the upper surface of the purification pipe 2 is provided with a driving motor 29, the driving motor 29 is located between the two filter plates 3, the output shaft of the driving motor 29 penetrates the purification pipe 2 and is connected with a rotating shaft 28, the outer side of the rotating shaft 28 is provided with a wind shield 27, the end of the wind shield 27 away from the air inlet pipe 1 is provided with a containing groove 30, the containing groove 30 is internally connected with a brush plate 31 through a spring rod, and the brush plate 31 is provided with brush hairs.

[0048] Each filter plate 3 is provided with a cleaning mechanism on both sides, the cleaning mechanism comprises a fixed rod 32, one end of the fixed rod 32 is connected with the purification pipe 2, the other end is provided with a limiting ring 33, the side close to the filter plate 3 of the limiting ring 33 is rotatably connected with a rotating disc 35, the side close to the limiting ring 33 of the rotating disc 35 is provided with a rotating rod 34, the rotating rod 34 is rotatably connected with the limiting ring 33, and a plurality of scraping plates 36 are arranged in an annular array on the side surface of the rotating disc 35.

[0049] It should be noted that the upper end of the fixed rod 32 is connected with the purification pipe 2 in a sliding manner, when the filter plate 3 is turned over, the filter plate 3 will drive the fixed rod 32 to slide on the purification pipe 2 with the axis of the filter plate 3 as the center.

[0050] Firstly, by setting two filter plates 3 and the baffle 27 in the purification pipe 2, when the air suction fan 5 is positively rotated, the air suction fan 5 will generate suction force, so that the air is sucked from the air inlet pipe 1 and discharged from the air outlet pipe 4, in this process, the air located on one side of the air inlet pipe 1 will enter the air inlet pipe 1 under the action of the suction force, and the air entering the air inlet pipe 1 will be divided into two parts by the baffle 27, and the air will be driven to pass through the filter plate 3 set in the purification pipe 2 under the action of the air suction fan 5, so as to complete the filtration of the air, by connecting two purification pipes 2 on one side of the air inlet pipe 1 and dividing the air entering the air inlet pipe 1 into two parts by the baffle 27, and by setting filter plates 3 in the two purification pipes 2 respectively, the filtration effect of the air is improved, so that the air inlet side of the filter plate 3 is fully utilized.

[0051] Secondly, when the filtration effect of the filter plate 3 on one side decreases after being used for a period of time, the air suction fan 5 connected with the filter plate 3 with decreased filtration effect is controlled to be reversed by the control unit, so that the air suction fan 5 changes from suction to blowing, the air is sucked into the air outlet pipe 4 and blown to the filter plate 3, and the baffle 27 is driven to rotate around the rotating shaft 28 by the driving motor 29, since the baffle 27 rotates, the air pressure at both ends of the air inlet pipe 1 will change with the rotation of the baffle 27, when the baffle 27 rotates to the left side near one end of the air inlet pipe 1, the air pressure on the left side will be greater than that on the right side, at this time, the air suction fan 5 on the left side is changed from suction to blowing, the air is sucked into the air outlet pipe 4 and blown to the filter plate 3, and the filter plate 3 is cleaned in one stage by the larger air pressure, so as to prevent the filter plate 3 from being blocked by dust and affect the filtration effect of the air.

[0052] Thirdly, when the driving motor 29 drives the rotating shaft 28 to rotate, the rotating shaft 28 drives the baffle 27 to rotate, so that the baffle 27 separates from the purification pipe 2 at one end away from the air inlet pipe 1 and rotates to the filter plate 3 on one side, in this process, since the baffle 27 separates from the purification pipe 2, the spring rod in the containing groove 30 will lose the restriction and will push the brush plate 31 to slide away from the baffle 27 under the elastic force of the spring rod, so that the bristles are exposed, when the side of the baffle 27 with the bristles rotates to the side of the filter plate 3, the side of the filter plate 3 with dust adhered is cleaned in two stages by the bristles, so as to further improve the dust cleaning effect of the filter plate 3.

[0053] Finally, when the wind deflector 27 contacts the rotating rod 34 arranged on the side of the filter plate 3 during rotation and continues to rotate in this direction, the wind deflector 27 will push the rotating rod 34 to move within the limiting ring 33, during which the rotating rod 34 will move within the limiting ring, so that the rotating rod 34 drives the rotating disc 35 to rotate and drives the scraper 36 to rotate on the side of the filter plate 3, through the horizontal cleaning of the filter plate 3 by the brush and the rotary cleaning of the scraper 36, the double cleaning of the side of the filter plate 3 is completed, and at the same time, since the air pressure and air flow rate in the purification pipe 2 during the rotation of the wind deflector 27 are in a state of change, when the air pressure in the purification pipe 2 to be cleaned changes from small to large, the gas in the purification pipe 2 is compressed to make the filter plate 3 vibrate, and through the horizontal cleaning of the filter plate 3 by the brush and the rotary cleaning of the scraper 36, the filter plate 3 is cleaned in three stages, so that the problem that part of the dust is always adhered to the filter plate 3 and cannot be effectively cleaned is prevented, and at the same time, the scraper 36 will contact the brush during rotation to clean the dust adhered to the brush, so that the problem that the cleaning effect of the brush is reduced after long-term use is prevented.

[0054] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
