[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 9 As shown, an energy-saving cleaning mechanism of the present invention includes a mounting seat 11, a dust collection assembly, a roller brush assembly and a crushing assembly.

[0032] The dust suction component is arranged at the front end of the mounting seat 11, and the dust suction component includes a collecting bin 2. The front end of the collecting bin 2 is provided with a feed port 21, and the rear end of the collecting bin 2 is provided with an air suction port 22. The roller brush component is arranged at the rear end of the mounting seat 11, and the roller brush component includes a roller brush 31 and a material receiving plate 32. The roller brush 31 is rotatably arranged at the lower end of the mounting seat 11, and the mounting seat 11 is provided with a motor 311 for driving the roller brush 31 to rotate. The material receiving plate 32 is arranged on the front side of the roller brush 31, and a storage cavity 321 is formed at the upper end of the material receiving plate 32. A suction port 2 33 is provided at a position corresponding to the storage cavity 321 on the mounting seat 11, and a plurality of walking wheels 16 for support are provided at the lower end of the mounting seat 11.

[0033] When in use, the mounting base 11 is mounted on the rear of the sweeper, so that the cleaning structure cooperates with the garbage bin 13, the disc brush 14 and the fan 15 on the sweeper to clean the garbage on the road. Specifically, Figures 1 to 8 As shown, during the walking process of the sweeper, the rotation of the disc brush 14 collects the garbage on the road surface and transports it to the front side of the collecting bin 2. As the sweeper moves, this part of the garbage enters the collecting bin 2 through the feeding port 21 for collection. At the same time, the roller brush 31 is driven to rotate by the motor 311 to sweep up the garbage on the ground and push it to the receiving plate 32. This part of the garbage is temporarily stored in the storage cavity 321 provided on the receiving plate 32. After the sweeper has worked for a certain period of time, the fan 15 is started to form a dust cloud inside the collecting bin 2 and the storage cavity 321. Negative pressure is formed, at this time, the garbage collected in the collection bin 2 can be sucked into the garbage bin 13 through the suction port 1 22, and the garbage collected in the storage chamber 321 can be sucked into the garbage bin 13 through the suction port 2 33. Therefore, in the process of cleaning the garbage, the garbage can be temporarily collected in the collection bin 2 and the storage chamber 321, and then the fan 15 can be started once at a certain interval to suck the garbage in the collection bin 2 and the storage chamber 321 into the garbage bin 13, so that the fan 15 can work intermittently, reduce energy consumption, and extend the life of the fan 15.

[0034] The crushing assembly is arranged in the collecting bin 2, and the crushing assembly includes a plurality of groups of matching vertical knives 41 and cutting knives 42. The vertical knives 41 are longitudinally installed in the collecting bin 2. A driving shaft 43 is rotatably installed in the collecting bin 2, and a motor 431 is installed on the collecting bin 2 for driving the driving shaft 43 to rotate. The cutting knives 42 are installed on the driving shaft 43. A material-pickup piece 44 is installed at the end of each cutting knife 42 away from the driving shaft 43. The material-pickup piece 44 includes a rotating shaft 441 and a plurality of material-pickup teeth 442. The rotating shaft 441 is arranged along the axial direction of the driving shaft 43, and one end is rotatably connected to the end of the cutting knife 42 through a torsion spring. The plurality of material-pickup teeth 442 are arranged in an axial array along the rotating shaft 441. When not under force, the extension direction of the material-pickup teeth 442 is consistent with the extension direction of the end of the cutting knife 42.

[0035] Specifically, Figures 1 to 7 As shown, after the garbage enters the collection bin 2, it will first contact the cutting knife 42 installed on the front side. The cutting knife 42 rotates counterclockwise under the drive of the motor three 431 to perform preliminary cutting on the incoming garbage. At the same time, during the rotation process, the cutting knife 42 can push the garbage backward to move it to the position of the vertical knife 41. When the garbage moves to the position of the vertical knife 41, the vertical knife 41 can further cut the garbage. At the same time, the vertical knife 41 and the cutting knife 42 can be staggered to provide a greater cutting force to ensure that the garbage is completely divided into smaller pieces. By crushing the garbage, it is convenient to subsequently suck this part of the garbage into the garbage bin 13 through the suction port 22. At the same time, it can avoid the suction port 22 from being blocked and affecting the normal use of the sweeper.

[0036] The cam 442 is engaged with the cutter 42 and the tooth 443 is engaged with the cutter 42. The cam 442 is engaged with the cutter 42 and the tooth 443 is engaged with the cutter 42. The cam 442 is engaged with the cutter 42 and the tooth 443 is engaged with the cutter 42. The garbage is squeezed, thereby the soil blocks in the garbage are squeezed and crushed, ensuring that the subsequently crushed soil blocks can be smoothly sucked into the garbage bin 13, thereby ensuring the garbage cleaning effect; then the driving shaft 43 continues to rotate, and the material-pickling tooth 442 will rotate in the opposite direction under the action of the torsion spring, so that the angle between the material-pickling tooth 442 and the end of the cutting knife 42 gradually increases, until the material-pickling tooth 442 is perpendicular to the bottom of the collecting bin 2, so that the material-pickling tooth 442 rotates to state three, at this time The driving shaft 43 continues to rotate, and the material-pickling tooth 442 will quickly reverse under the action of the torsion spring, so that the extension direction of the material-pickling tooth 442 is consistent with the extension direction of the end of the cutting knife 42. In this process, the garbage located at the rear side of the material-pickling tooth 442 can be pushed through the rapid rotation of the material-pickling tooth 442, and the garbage is lifted to the air suction port 22, which is convenient for improving the suction efficiency of the garbage, thereby improving the cleaning efficiency.

[0037] After the sweeper has been working for a period of time, garbage such as leaves and plastic bags may be entangled on the material-diverting piece 44, affecting the normal use of the material-diverting piece 44. Therefore, in some embodiments, a material-blocking plate 45 is provided in the collection bin 2, and the material-blocking plate 45 is longitudinally arranged on the rear side of the crushing assembly, and the lower end of the material-blocking plate 45 has a space for garbage to pass through. The material-diverting teeth 442 are in a plate-like structure, and the lower part of the material-blocking plate 45 is provided with a cutting groove 451 that is compatible with the material-diverting teeth 442. When the driving shaft 43 rotates, the material-diverting teeth 442 can pass through the corresponding cutting groove 451 to crush the garbage entangled on the material-diverting teeth 442.

[0038] Specifically, Figures 2 to 7 As shown, when the drive shaft 43 rotates, it can drive the cutting knife 42 and the material-discharging member 44 to rotate synchronously. In this process, the garbage entering the collection bin 2 can be crushed through the cooperation of the cutting knife 42 and the vertical knife 41. At the same time, the garbage wrapped around the material-discharging tooth 442 can be crushed through the cooperation between the material-discharging tooth 442 and the cutting groove 451. When the material-discharging tooth 442 is disengaged from the cutting groove 451, the crushed garbage wrapped around the material-discharging tooth 442 will be scraped off by the side wall of the cutting groove 451, which effectively prevents the garbage from being entangled around the material-discharging member 44 and ensures the normal use of the material-discharging member 44. In addition, when the garbage wrapped around the material-discharging tooth 442 is scraped off, this part of the garbage is at a higher height and can be directly sucked into the garbage bin 13 through the suction port 22.

[0039] In some embodiments, the receiving plate 32 includes a U-shaped portion and an arc-shaped portion connected to the rear side of the U-shaped portion. A groove is formed on the U-shaped portion, namely, a storage cavity 321, which is used to temporarily store garbage cleaned by the roller brush 31. The arc surface of the arc-shaped portion faces the roller brush 31, which is used to guide the garbage into the storage cavity 321 and reduce the accumulation of garbage on the receiving plate 32. The arc surface design of the arc-shaped portion can better adapt to the movement trajectory of the roller brush 31, ensuring that the garbage can smoothly enter the storage cavity 321.

[0040] In some embodiments, the second air suction port 33 is arranged corresponding to the middle part of the storage chamber 321, and an auger assembly is installed in the storage chamber 321. The auger assembly includes an auger shaft 34 and two sections of auger blades 35. The auger shaft 34 is rotatably installed in the storage chamber 321, and a second motor 341 for driving the auger shaft 34 to rotate is provided on the mounting seat 11. The two sections of auger blades 35 are oppositely installed at both ends of the auger shaft 34, that is, the spiral directions of the two sections of auger blades 35 are opposite.

[0041] Specifically, Figure 2 , Figure 8 and Fig. 9As shown, starting the fan 15 can suck the garbage in the storage chamber 321 into the garbage bin 13 through the suction port 2 33. During this process, starting the motor 2 341 can drive the auger shaft 34 to rotate, and drive the two sections of the auger blades 35 to rotate synchronously. Since the spiral directions of the two sections of the auger blades 35 are opposite, the garbage in the storage chamber 321 can be transported from both ends to the middle, so that the garbage can be effectively concentrated in the middle position of the storage chamber 321, so that the suction port 2 33 arranged in the middle of the storage chamber 321 can suck the garbage, thereby improving the garbage suction efficiency.

[0042] In some embodiments, two stripper plates 36 are installed in the middle of the auger shaft 34 .

[0043] Specifically, Figure 8 and Fig. 9 As shown, when the auger shaft 34 rotates, it can drive the two material-shifting plates 36 to rotate synchronously. As the material-shifting plates 36 rotate, the garbage concentrated in the middle of the storage chamber 321 can be shifted and lifted up, assisting the fan 15 in sucking in the garbage, thereby further improving the garbage suction efficiency.

[0044] In some embodiments, two material guide plates 23 are provided at the front end of the collecting bin 2 . The two material guide plates 23 are symmetrically arranged in a trumpet shape, and a brush 24 is provided at the lower end of each material guide plate 23 .

[0045] Specifically, Figure 2 and Figure 3 As shown, the guide plate 23 is used to guide the garbage on the front side of the collecting bin 2 into the collecting bin 2. Its trumpet-shaped design can expand the garbage receiving area, reduce the accumulation and blockage of garbage at the feed port 21, and ensure that the garbage can smoothly enter the collecting bin 2. The brush 24 is used to clean the ground to ensure that the garbage can be collected more thoroughly. The brush 24 is usually made of soft bristles and can effectively clean the dust and small particles of garbage on the ground.

[0046] In some embodiments, a baffle 25 is provided at the front end of the collecting bin 2 , and the baffle 25 is inclined from top to bottom toward the rear end of the collecting bin 2 .

[0047] Specifically, Figure 2 and Figure 5 As shown, by providing an inclined baffle 25, the area of ​​the feed port 21 can be effectively reduced, and the wind speed in the collection bin 2 can be increased when the fan 15 is working, while not causing much impact on the collection of garbage.

[0048] In some embodiments, a plurality of flow dividers 26 are disposed at the bottom of the collecting chamber 2 , and each flow divider 26 is provided with a pointed end.

[0049] Specifically, Figures 2 to 5As shown, in the process of the material-shifting member 44 shifting the garbage, the tip on the diverter 26 can effectively cut and disperse the garbage, especially for garbage that is easy to entangle, such as plastic bags and leaves, and can effectively prevent garbage accumulation, ensuring that the garbage can be evenly distributed and smoothly enter the subsequent processing link. In addition, in the process of the material-shifting member 44 pressing and crushing the soil blocks in the garbage, the tip on the diverter 26 can effectively improve the crushing effect of the soil blocks.

[0050] In some embodiments, a discharge port 27 is provided at the rear end of the collecting bin 2 .

[0051] Specifically, Figures 5 to 7 As shown, during the movement of the sweeper, the garbage located at the front side of the collecting bin 2 can enter the collecting bin 2, and some stones will also enter the collecting bin 2. When the fan 15 is started, the garbage and stones can be simultaneously sucked into the garbage bin 13. For some heavier stones, if the negative pressure provided by the fan 15 is not enough to suck up these stones, these stones will gradually accumulate at the rear end of the collecting bin 2 to form a slope. After completing a period of cleaning work, the staff can manually open the discharge port 27 to clean out the stones accumulated in the collecting bin 2 to avoid too many stones in the collecting bin 2 affecting the normal cleaning of the garbage.

[0052] like Figures 1 to 9 As shown, the present invention also provides a sweeper, which includes a body 1 and the above-mentioned cleaning mechanism. The cleaning mechanism is mounted on the rear of the body 1 and can be lifted up when not in use. The body 1 is also provided with a water tank 12, a garbage bin 13, a disc brush 14 and a fan 15. The specific functions and structures of the cleaning mechanism can be found in the above-mentioned embodiments, and will not be described one by one here.

[0053] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
