The air inlet 4 and the air outlet 5 are respectively rotatably connected by sealed bearings, the outer ring of the sealed bearing is fixedly connected to the air inlet 4 or the air outlet 5, the inner ring of the sealed bearing is fixedly connected to the outer tube 6 or the inner tube 7, the air inlet 4, the air outlet 5, the outer tube 6 and the inner tube 7 are coaxially arranged, a plurality of air outlet holes 8 are arranged on the outer periphery of the inner tube 7, and ventilation holes 9 are respectively arranged on the outer periphery of the outer tube 6 corresponding to the air outlet holes 8, the air outlet holes 8 can completely overlap with the corresponding ventilation holes 9, and can also be completely misaligned. When the air outlet holes 8 overlap with the ventilation holes 9, the air inlet 4 is connected with the inside of the dust removal box 2. On the contrary, when the air outlet 8 and the ventilation hole 9 are completely misaligned, the air inlet 4 is no longer connected with the inside of the dust removal box 2. An arc-shaped slide groove 10 is provided on the inner periphery of the outer tube 6. A slide rod 11 is slidably installed in the arc-shaped slide groove 10. In the initial state, the slide rod 11 is located in the middle of the arc-shaped slide groove 10. The slide rod 11 is fixedly connected to the inner tube 7. The inner tube 7 and the outer tube 6 are respectively connected with the dust removal box 2 through the reset elastic member 12. Under the action of the reset elastic member, the air outlet 8 and the ventilation hole 9 are completely misaligned. The corresponding ventilation holes 9 remain completely overlapped, one side of the outer periphery of the outer tube 6 is fixedly connected to one end of the filter gauze 13, and the other end of the filter gauze 13 is fixedly connected to the sealing plate 14. The filter gauze 13 is wrapped around the outer periphery of the outer tube 6. The sealing plate 14 can seal the connecting groove 15 between the dust collecting box 1 and the dust removal box 2. The top side of the sealing plate 14 is in close contact with the top side of the inner wall of the dust collecting box 1. An air inlet hole 16 is also provided on the outer periphery of the outer tube 6, and the air inlet hole 16 is connected to the air outlet 5. The present invention has a simple structure and an ingenious design. Several layers of filter gauze 13 are wound around the outer periphery of the outer tube 6 to form finer filter holes. The filter holes of the filter gauze 13 are offset from each other to form smaller filter holes, thereby improving the filtering accuracy and reducing the demand for the fineness of the filter gauze 13. When the filter gauze 13 needs to be cleaned, it is only necessary to tear the filter gauze 13 off the outer periphery of the outer tube 6 and unfold the filter gauze 13 to facilitate dust to fall off the filter gauze 13. The cleaning is convenient, can meet actual needs, and is suitable for promotion.When using the present invention, firstly, the turbid air to be filtered and purified is passed into the inner tube 7 from the air inlet 4. At this time, the air outlet 8 and the ventilation hole 9 overlap with each other, and the turbid air enters the dust removal box 2 and is filtered by the filter gauze 13 to form clean air. The clean air enters the outer tube 6 through the air inlet 16 and is finally discharged from the dust removal box 2 through the air outlet 5. The filtered dust and debris remain in the dust removal box 12 and gather on the top side of the sealing plate 14, completing the filtration of the turbid air. When it is necessary to clean the dust on the filter gauze 13, you can directly pull it downwards. The sealing plate 14 pulls off the filter gauze 13 from the outer periphery of the outer tube 6, and the filter gauze 13 drives the outer tube 6 to rotate, and the reset elastic member 12 connected to the outer tube 6 stores energy, and the outer tube 6 and the arc-shaped slide groove 10 rotate relative to the slide rod 11, until the slide rod 11 moves to one end of the arc-shaped slide groove 10, the air outlet 8 and the ventilation hole 9 are completely misaligned, and the turbid air from the outside no longer enters the dust removal box 2, and the outer tube 6 continues to rotate, and the outer tube 6 drives the inner tube 7 to rotate through the arc-shaped slide groove 10 and the cross bar 11, and the reset elastic member 12 connected to the inner tube 7 stores energy, and the filter gauze 13 is unfolded. During the process, dust and debris attached to the filter gauze 13 fall off the filter gauze 13. At this time, the filter gauze 13 is knocked to make the filter gauze 13 vibrate, which is conducive to the dust falling. The fallen dust accumulates in the dust collecting box 1, and the dust in the dust collecting box 1 can be cleaned through the dust discharge port 3. After cleaning, the sealing plate 14 is loosened, and under the action of the energy release of the reset elastic member 12, the outer tube 6 and the inner tube 7 rotate in the opposite direction, and the filter gauze 13 is rewound around the outer periphery of the outer tube 6, and the air outlet 8 and the ventilation hole 9 resume overlap. When cleaning the dust on the filter gauze 13, you can also directly turn The inner tube 7 is moved, and the reset elastic member 12 connected to the inner tube 7 stores energy, and the cross bar 11 slides in the arc-shaped slide groove 10 and slides to one end, and the air outlet 8 and the ventilation hole 9 no longer overlap, and as the inner tube 7 continues to rotate, the inner tube 7 drives the outer tube 6 to rotate, and the reset elastic member 12 connected to the outer tube 6 stores energy. At the same time, under the gravity of the sealing plate 14, the filter gauze 13 is torn off, thereby cleaning the dust on the filter gauze 13, and loosening the inner tube 7. The above process is carried out in reverse order, and the filter gauze 13 is rewound around the outer periphery of the outer tube 6, and the air outlet 8 and the ventilation hole 9 overlap again.

[0021] Specifically, if Figure 1 , Figure 3 and Figure 4As shown, the reset elastic member 12 described in this embodiment is a spring, which is mounted on the outer periphery of the corresponding inner tube 7 or outer tube 6. One end of the spring is fixedly connected to the inner tube 7 or outer tube 6, and the other end is fixedly connected to the dust box 2. The outer peripheries of the outer tube 6 and the inner tube 7 are respectively fixedly installed with retaining rings 30, and the top side of the inner wall of the dust box 1 is provided with a corresponding elastic sealing ring 100 corresponding to the sealing plate 14. When the outer tube 6 and the inner tube 7 rotate forward, one end of the spring is driven to move, so that the spring is tightened and stored. On the contrary, when the spring releases energy, it drives the outer tube 6 and the inner tube 7 to rotate in the opposite direction. The spring is located between the corresponding retaining ring 30 and the side wall of the dust box 2, so as to prevent the spring from being scattered. The sealing ring 100 can increase the sealing performance between the sealing plate 14 and the inner wall of the dust box 1.

[0022] Specifically, Figure 1 As shown, the dust removal boxes 2 described in this embodiment are provided with several and are evenly distributed on the top side of the dust collection box 1. The same air inlet box 40 is provided in the middle of the several dust removal boxes 2. The air inlet 4 is connected to the inside of the air inlet box 40 through a connecting pipe, and an air inlet slot 41 is provided on the air inlet box 40. The air to be purified is passed into the air inlet box 40 through the air inlet slot 41, and then passed into the corresponding dust removal boxes 2 through the connecting pipes.

[0023] Further, such as Figure 1 As shown, in this embodiment, a suction fan 50 is installed at the air inlet slot 41, and the suction fan 50 is a dust-proof fan. When the suction fan 50 is working, it can send the outside air into the air inlet box 40.

[0024] Furthermore, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the interior of the inner tube 7 described in this embodiment is fixedly installed with a bevel gear 61 through a support shaft 60, and the bevel gear 61 and the support shaft 60 are respectively coaxially arranged with the corresponding inner tube 7, and the same incomplete bevel gear 62 is arranged in the middle of several bevel gears 61, and the bevel gear 61 can be respectively meshed with the incomplete bevel gear 62, and the bevel gear 61 can also be not meshed with the incomplete bevel gear 62, and several bevel gears 61 are evenly distributed along the circumference of the incomplete bevel gear 62, and the incomplete bevel gear 62 is fixedly installed on the coaxial vertical shaft 63, and the vertical shaft 63 is rotatably installed on the air inlet box 40, and a protective cover 64 is set on the outer side of the incomplete bevel gear 62 and the bevel gear 61, and the protective cover 64 is fixed on the air inlet box 40, and the protective cover 64 is provided with a reserved hole corresponding to the support shaft 60, and the support shaft 60 is respectively rotatably connected with the corresponding reserved hole through a sealed bearing, and the protective cover 64 can reduce the influence of dust in the air on the meshing of the incomplete bevel gear 62 and the bevel gear 61. .

[0025] Furthermore, Figure 1As shown, the lower end of the vertical shaft 63 in this embodiment is fixedly connected to the output shaft of the drive motor 90, and the drive motor 90 is fixed on the air inlet box 40. When the drive motor 90 is powered, the output shaft of the drive motor 90 can drive the vertical shaft 63 to rotate.

[0026] Furthermore, Figure 1 , Figure 3 and Figure 4 As shown, the two sides of the filter gauze 13 described in this embodiment are respectively fixed with flexible ropes 70, and the upper end of the filter gauze 13 is wide and the lower end is narrow. The flexible rope 70 can increase the tensile strength of the filter gauze 13. When the lower end of the filter gauze 13 is pulled by the sealing plate 14, the filter gauze 13 is stretched and easily deformed, resulting in a decrease in filtering accuracy. At this time, under the action of the flexible rope 70, the tensile deformation of the filter gauze 13 can be reduced; and because the upper end of the filter gauze 13 is wide and the lower end is narrow, when the flexible rope 70 is wound around the outer periphery of the outer tube 6 with the filter gauze 13, the flexible rope 70 is spirally distributed, so that the outer flexible rope 70 is wound around the inner filter gauze 13, increasing the sealing effect between the filter gauze 13 and the outer tube 60, and reducing dust from entering the air inlet 16 along the side of the filter gauze 13.

[0027] Furthermore, Figure 1 As shown, the sealing plate 14 of this embodiment is connected to the bottom side of the dust box 1 by a plurality of elastic drawstrings 80. The elastic drawstrings 80 can play a guiding role, so that the sealing plate 14 moves up and down, and at the same time, the filter gauze 13 is more neatly wound around the outer periphery of the outer tube 6, and the elastic drawstrings 80 increase the force of the sealing plate 14 moving downward. When the sealing plate 14 abuts against the top side of the inner wall of the dust box 1, the elastic drawstrings 80 are stretched, and at this time, the elastic drawstrings 80 cannot overcome the resistance of the reset elastic member 12 to rotate the outer tube 6.

[0028] Furthermore, as shown in the figure, the side wall of the dust box 1 described in this embodiment is respectively fixed with a plurality of protrusions 20 corresponding to the sealing plate 14, and one end of the sealing plate 14 can slide and contact with the corresponding protrusion 20. When the sealing plate 14 moves up and down, one end thereof can slide along the corresponding protrusion 20, so that the sealing plate 14 is separated from the corresponding side wall of the dust box 1, and the sealing plate 14 is reset again after being separated from the corresponding protrusion 20, so that the sealing plate 14 swings, and the dust on the top side of the sealing plate 14 slides off.

[0029] Furthermore, as shown in the figure, the inner tube 7 of the present embodiment is located at one end of the outer tube 6 and fixedly mounted with a rotating tube 110, the outer periphery of the rotating tube 110 is in airtight sliding contact with the inner periphery of the outer tube 6, and a ventilation groove 111 is provided on the rotating tube 110 corresponding to the air inlet hole 16. When the air outlet hole 8 coincides with the ventilation hole 9, the ventilation groove 111 coincides with the air inlet hole 16, and conversely, when the air outlet hole 8 is completely misaligned with the ventilation hole 9, the ventilation groove 111 is completely misaligned with the air inlet hole 16, thereby reducing the dust remaining in the dust removal box 2 from entering the outer tube 6 through the air inlet hole 16.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
