[0027] See also Figure 1 , Figure 1This is a structural schematic diagram of a dust filtering structure in a dust suction unit of a sweeper in one embodiment of the utility model. A dust filtering structure in a dust suction unit of a sweeper comprises a filtering mechanism 1 and a cleaning mechanism 2. The filtering mechanism 1 comprises a filter housing 11 and a filter screen 131. Two air ports 12 are symmetrically provided on the filter housing 11. A mounting plate 13 is arranged in the filter housing 11, and the filter screen 131 is located between the two air ports 12. The cleaning mechanism 2 comprises a driving part 21, an extension plate 22 and a cleaning brush plate 23. The output end of the driving part 21 is connected to the extension plate 22 and is used to drive the extension plate 22 to rotate. The end of the extension plate 22 is connected to the cleaning brush plate 23 slidably arranged on the mounting plate 13.

[0028] In this embodiment, the dust suction unit on the sweeper sucks the dust from the air port 12 into the filter housing 11 through the air port 12, and filters the dust in the gas through the filter screen 131 on the mounting plate 13. During the long-term use of the filter screen 131, the filter hole surface will be clogged. At this time, the extension plate 22 is driven by the driving part 21 to perform a circular motion, and the cleaning brush plate 23 is driven by the extension plate 22 to move in an arc on the mounting plate 13, and the filter holes on the surface of the filter screen 131 are cleaned, so as to ensure the filtering effect of the filter screen 131. The device is simple to operate and can achieve the effect of cleaning the filter screen 131 without frequently installing and disassembling the filter screen 131, thereby greatly improving the service life of the filter screen 131.

[0029] In one embodiment, see Figure 1 In order to improve the working efficiency of the mounting plate 13 and the filter screen 131, the mounting plate 13 and the filter screen 131 are both arc-shaped plates, and the filter housing 11 is a circular housing.

[0030] In this embodiment, an arc-shaped mounting plate 13 and a filter screen 131 are used, which are conveniently installed in a circular filter housing 11 and can effectively allocate the internal space of the filter housing 11. The filter screen 131 can directly contact the gas to filter the dust in the gas.

[0031] In one embodiment, see Figure 2-3 In order to facilitate the subsequent cleaning of dust, in some embodiments, a dust accumulation groove 14 is provided in the filter housing 11 and at one end close to the filter screen 131, and a mounting end 15 is also provided in the filter housing 11, and the mounting end 15 includes two positioning cylinders 151 and a cover plate 152; the two positioning cylinders 151 are installed in the filter housing 11, and a plurality of first positioning holes 1511 are provided at the upper end of the filter housing 11, and a positioning rod 1521 for extending into the positioning cylinder 151 is fixed at the lower end of the cover plate 152, and a plurality of second positioning holes 1522 corresponding to the first positioning holes 1511 are provided on the cover plate 152, and mounting bolts 1523 are threadedly connected to the first positioning holes 1511 and the second positioning holes 1522.

[0032] In this embodiment, a dust accumulation groove 14 is opened on the filter shell 11, so that the cleaning mechanism 2 can conveniently collect the dust cleaned on the filter screen 131 and drop it into the dust accumulation groove 14, and the lower end of the dust accumulation groove 14 is connected to a dust accumulation shell 24, so that it is convenient to collect dust in a centralized manner. Subsequent staff only need to clean the dust accumulation shell 24 regularly without frequently installing and disassembling the filter screen 131, which greatly improves the service life of the filter screen 131.

[0033] In one embodiment, see Figure 1-3 In order to facilitate the cleaning of the filter screen 131, in some embodiments, the driving unit 21 includes a motor 211 and a shaft 212; the motor 211 is installed at the lower end of the filter housing 11, the output end of the motor 211 is connected to the shaft 212, one axial end of the shaft 212 extends to the inside of the filter housing 11, an extension plate 22 is fixed on the shaft 212, and the air port 12 includes an air inlet 121 and an air outlet 122; the air inlet 121 and the air outlet The openings 122 are respectively opened on both sides of the filter shell 11, and a filter screen 131 is arranged between the air inlet 121 and the air outlet 122; the air inlet 121 and the air outlet 122 are both connected with an air supply mechanism 3, and the air supply mechanism 3 includes an air inlet pipe 31 and an air outlet pipe 32; the air inlet pipe 31 is connected with the air inlet 121, and the air outlet pipe 32 is connected with the air outlet 122, and the cleaning brush plate 23 is an n-shaped plate body, and the inner wall of the cleaning brush plate 23 is bonded with bristles.

[0034] In this embodiment, when it is necessary to clean the surface of the filter 131, the motor 211 is started, the motor 211 drives the shaft 212 to operate, the shaft 212 drives the extension plate 22 to perform a circular motion, and the extension plate 22 drives the cleaning brush plate 23 to rotate on the mounting plate 13, and the bristles on the cleaning brush plate 23 are used to clean the filter holes on the filter 131. The cleaned dust falls into the dust accumulation groove 14 and enters the dust accumulation shell 24 for centralized collection.

[0035] In order to better understand the present invention, the following Figures 1 to 4The technical solution of the utility model is described in detail: the dust is sucked into the vehicle body through the dust suction unit inside the sweeper, and the gas is introduced into the filter housing 11 from the air inlet 121 through the air inlet pipe 31. The gas flows in the filter housing 11 and contacts the filter screen 131 on the mounting plate 13. The dust in the gas is filtered by the filter screen 131 and remains on the surface of the filter screen 131. The filtered gas passes through the filter housing 11 and is discharged from the air outlet 122 and the air outlet pipe 32. When the filter screen 131 needs to be cleaned, the motor 211 is started, and the shaft 21 is driven by the motor 211. 2 performs circular motion, drives the extension plate 22 to rotate through the shaft body 212, and drives the cleaning plate 23 to slide on the mounting plate 13 through the extension plate 22, and cleans the surface of the filter screen 131 through the bristles on the cleaning plate 23, so as to achieve the effect of cleaning the filter holes on the surface of the filter screen 131, and the cleaned dust falls into the dust accumulation groove 14, and finally falls from the dust accumulation groove 14 into the dust accumulation shell 24 for centralized collection. Since the dust accumulation shell 24 is detachably connected to the filter shell 11, when it is necessary to deal with the dust inside the dust accumulation shell 24 later, it only needs to disassemble the dust accumulation shell 24.

[0036] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
