Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a dirt scraping structure and a cleaning equipment. Background Art

[0002] Cleaning equipment such as sweeping robots usually have two ways of mopping the floor. One is a flat mop that vibrates and mops the floor, and the other is a turntable mop that rotates and mops the floor. However, both mopping methods have the disadvantage that the mop wipes everything and cannot self-clean. In order to achieve self-cleaning of the mop, the cleaning equipment is upgraded to a roller mop or a crawler mop. Taking the roller mop as an example, when the mop rotates and cleans, the dirt on the mop is scraped off by the scraper. The scraped dirt is first collected in the dirt collection tank and then sucked into the sewage tank, while the mop is self-cleaning.

[0003] However, when the cleaning equipment is used for mopping, serious water stains often appear on both sides of the mop. Such water stains are usually caused by water leaking along the edge of the scraper, which not only affects the cleaning effect, but also may damage the floor material. Utility Model Content

[0004] In view of this, the utility model provides a dirt scraping structure and a cleaning device to solve the problem of serious water stains on both sides of the mop when the cleaning device is mopping the floor.

[0005] In a first aspect, the utility model provides a dirt scraping structure, comprising:

[0007] The guide structure is located below the scraper plate; the guide structure includes two guide members, which are respectively arranged on both sides of the scraper plate along the length direction of the scraper plate and abut against the scraper edge to guide water to the sewage collecting tank.

[0008] Beneficial effect: when the mop rotates or moves relative to the scraper plate, the scraping edge of the scraper plate scrapes off the dirt on the mop, and the scraped dirty water will hang on the bottom of the scraper plate due to the tension, and crawl along the length direction of the scraper plate toward the two sides of the bottom surface, which will easily cause water stains on both sides of the mop; the guide structure is located under the scraper plate, and the two guide members are respectively arranged on both sides of the length direction of the scraper plate and abut against the scraping edge, which can guide the dirty water on the bottom of the scraper plate and guide it to fall into the dirt collection tank, effectively guiding the water on both sides of the length direction of the scraper plate, avoiding water leakage on both sides of the mop when mopping the floor, achieving uniform water stains on the ground when mopping the floor, greatly improving the cleaning effect, and at the same time avoiding the potential damage to the floor caused by serious water stains on both sides of the mop.

[0009] In an optional embodiment, the guide member includes an abutment end and a guide surface, the abutment end abuts against one side of the scraping edge in the length direction; the guide surface is arranged at the bottom of the guide member and connected to the bottom surface of the abutment end, the height of the guide surface protruding from the scraping plate gradually increases in the direction away from the abutment end, and the lowest point of the guide surface protruding from the bottom of the scraping plate is located above the dirt collecting trough.

[0010] Beneficial effect: the abutting end abuts against one side of the scraping edge in the length direction, and the sewage can be directly guided to the guide surface while being scraped off. The height of the guide surface protruding from the scraping plate gradually increases in the direction away from the abutting end, that is, the height of the guide surface gradually decreases in the direction away from the abutting end. The sewage can be guided to the lowest point of the guide surface under the action of gravity, and the lowest point is located above the sewage collection tank. The sewage guided to the lowest point of the guide surface can naturally fall into the sewage collection tank under the action of gravity, and can be pumped away together with other sewage in the sewage collection tank, so as to avoid the sewage falling to other locations and causing unnecessary damage.

[0011] In an optional embodiment, the flow guide further includes:

[0012] an abutting wall, one end of which is the abutting end, and the other end of which extends along the width direction in a direction away from the scraping edge;

[0013] A guide wall has one end connected to the other end of the abutting wall and the other end extending along the length direction of the scraper plate. The bottom surface of the guide wall forms the guide surface.

[0014] Beneficial effect: The other end of the abutment wall extends along the width direction toward the direction away from the scraping edge, and the other end of the guide wall extends along the length direction of the scraping plate, which can guide the lowest point of the guide surface to the middle position of the scraping plate, avoiding overflow after accumulating on the water guide surface due to too much sewage.

[0015] In an optional embodiment, the outer side surface of the scraper plate in the length direction is the first side surface; the outer side surface of the abutment wall in the length direction is the second side surface; and the second side surface is arranged close to the first side surface in the length direction.

[0018] Beneficial effects: the second side surface is arranged to protrude outward from the first side surface, which can better guide the side of the scraper plate in the length direction; since the gap between the body of the cleaning equipment and the scraper plate is usually small, in order to avoid the guide member affecting other parts of the body, the distance L of the second side surface protruding from the first side surface should be set to be smaller; and the distance L of the second side surface protruding from the first side surface ≤ 3mm can also prevent the guide member from directing water out of the scraper plate and the outside of the mop, avoiding other hidden dangers.

[0019] In an optional embodiment, a height difference m between a bottom surface of the abutting wall and a bottom surface of the scraping plate satisfies: m≤3 mm.

[0020] Beneficial effect: the bottom surface of the abutment wall may be higher than the lowest point of the guide surface by m, or the bottom surface of the abutment wall may be lower than the lowest point of the guide surface by a height difference of m; because the thickness of the sewage scraped off by the scraper is limited, if the height difference m between the bottom surface of the abutment wall and the lowest point of the guide surface is large, the sewage gathered together cannot reach the height of the height difference and will be guided away by the abutment wall instead of being guided to the sewage collecting tank through the guide surface. Therefore, the height difference m≤3mm can make the guide surface and the abutment wall have a better guide effect.

[0021] In an optional embodiment, a height difference n between a connection point between the guide surface and the abutment wall and a lowest point of the guide surface satisfies: 1 mm ≤ n ≤ 8 mm.

[0022] Beneficial effects: When the height difference is too small, the diversion effect is poor and sewage is easy to overflow. When the height difference is too large, it occupies a large space and is easy to penetrate into the sewage tank. When the water level in the sewage tank is high, it is easy to cause reverse overflow.

[0067] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0068] Combine the following Figures 1 to 14 , describing an embodiment of the utility model.

[0069] According to an embodiment of the utility model, on the one hand, a scraping structure 200 is provided, comprising a scraping plate 1 and a guide structure; at least one side edge of the scraping plate 1 in the width direction is a scraping edge 11, and the scraping edge 11 is used to scrape off dirt on the mop 100; the guide structure is located below the scraping plate 1; the guide structure comprises two guide members 2, which are respectively arranged on both sides of the scraping plate 1 along the length direction of the scraping plate 1, and abut against the scraping edge 11, so as to guide water to the dirt collecting tank 300.

[0070] When the mop 100 rotates or moves relative to the scraper plate 1, the scraping edge 11 of the scraper plate 1 scrapes off the dirt on the mop 100. The scraped dirty water will hang on the bottom surface of the scraper plate 1 due to the tension, and crawl toward the two sides of the bottom surface along the length direction of the scraper plate 1, which is easy to cause water stains on both sides of the mop 100; the guide structure is located below the scraper plate 1, and the two guide members 2 are respectively arranged on both sides of the length direction of the scraper plate 1 and abut against the scraping edge 11, which can guide the dirty water on the bottom surface of the scraper plate 1 and guide it to fall into the dirt collecting tank 300, effectively guiding the water on both sides of the length direction of the scraper plate 1, avoiding water leakage on both sides of the mop 100 when mopping the floor, achieving uniform water stains on the ground when mopping the floor, greatly improving the cleaning effect, and at the same time avoiding the potential damage to the floor caused by serious water stains on both sides of the mop 100.

[0071] In one embodiment, the guide member 2 includes an abutment end 21 and a guide surface 22, and the abutment end 21 abuts against one side of the scraping edge 11 in the length direction; the guide surface 22 is arranged at the bottom of the guide member 2 and is connected to the bottom surface of the abutment end 21, and the height of the guide surface 22 protruding from the scraping plate 1 gradually increases in the direction away from the abutment end 21, and the lowest point 25 of the guide surface 22 protruding from the bottom of the scraping plate 1 is located above the dirt collecting tank 300.

[0072] The abutting end 21 abuts against one side of the scraping edge 11 in the length direction, and can directly guide the sewage to the guide surface 22 while scraping it off. The height of the guide surface 22 protruding from the scraping plate 1 gradually increases in the direction away from the abutting end 21, that is, the height of the guide surface 22 gradually decreases in the direction away from the abutting end 21. The sewage can be guided to the lowest point 25 of the guide surface 22 under the action of gravity, and the lowest point 25 is located above the sewage collection tank 300. The sewage guided to the lowest point 25 of the guide surface 22 can naturally fall into the sewage collection tank 300 under the action of gravity, and can be pumped away together with other sewage in the sewage collection tank 300, so as to avoid the sewage falling to other locations and causing unnecessary damage.

[0073] In one embodiment, the guide member 2 also includes an abutment wall 23 and a guide wall 24; one end of the abutment wall 23 is the abutment end 21, and the other end extends along the width direction toward the direction away from the scraping edge 11; one end of the guide wall 24 is connected to the other end of the abutment wall 23, and the other end extends along the length direction of the scraping plate 1, and the bottom surface of the guide wall 24 forms the guide surface 22.

[0074] The other end of the abutment wall 23 extends along the width direction toward the direction away from the scraping edge 11, and the other end of the guide wall 24 extends along the length direction of the scraping plate 1, which can guide the lowest point 25 of the guide surface 22 to the middle position of the scraping plate 1 to avoid overflowing after accumulating on the water guide surface due to too much sewage.

[0075] As a convertible embodiment, the guide member 2 may include a protrusion, one side of the protrusion in the width direction of the scraper plate 1 is the abutment end 21, and the bottom surface of the protrusion is the guide surface.

[0076] In one embodiment, the outer side surface of the scraper plate 1 in the length direction is the first side surface 12; the outer side surface of the abutment wall 23 in the length direction is the second side surface 26; the second side surface 26 is arranged close to the first side surface 12 in the length direction.

[0077] The first side surface 12 is close to the second side surface 26, so that the sewage in the length direction of the scraper plate 1 can be better guided to the sewage collecting tank 300 to avoid sewage overflow. Specifically, the length direction is the length direction of the scraper plate 1; the outer side surface of the abutting wall 23 is the side surface facing away from the other guide member 2 in the length direction of the scraper plate 1.

[0078] In a specific embodiment, the first side surface 12 and the second side surface 26 are arranged on the same plane, which can not only have a better guiding effect on the sewage, but also prevent the guide member 2 from occupying the space outside the scraper plate 1.

[0079] Specifically, in another embodiment, the second side surface 26 is disposed to protrude outward from the first side surface 12, and a distance L of the second side surface 26 protruding from the first side surface 12 satisfies L≤3 mm.

[0080] The second side surface 26 is arranged to protrude outward from the first side surface 12, so as to better guide the side of the scraper plate 1 in the length direction; since the gap between the body of the cleaning device and the scraper plate 1 is usually small, in order to prevent the guide member 2 from affecting other parts of the body, the distance L of the second side surface 26 protruding from the first side surface 12 should be set to be small; and the distance L of the second side surface 26 protruding from the first side surface 12 is ≤3mm, which can also prevent the guide member 2 from directing water out of the scraper plate 1 and the outside of the mop 100, thereby avoiding other hidden dangers.

[0081] In a specific embodiment, the second side surface 26 is disposed to protrude outward from the first side surface 12, and a distance L of the second side surface 26 protruding from the first side surface 12 is 3 mm.

[0082] Specifically, in another embodiment, the second side surface 26 is disposed to protrude inwardly from the first side surface 12 , and a distance R between the second side surface 26 and the first side surface 12 satisfies R≤10 mm.

[0083] The second side surface 26 is arranged to protrude inward from the first side surface 12. Under the action of tension and the guide surface 22, the sewage on the side of the scraper 1 will also be guided to the sewage collecting tank 300; and the distance R between the second side surface 26 and the first side surface 12 is ≤10mm, which can avoid the sewage being unable to be guided to the sewage collecting tank 300 due to the second side surface 26 being too far away from the first side surface 12.

[0084] In a specific embodiment, the second side surface 26 is disposed to protrude inwardly from the first side surface 12 , and a distance R between the second side surface 26 and the first side surface 12 is 10 mm.

[0085] In one embodiment, the height difference m between the bottom surface of the abutting wall 23 and the bottom surface of the scraping plate 1 satisfies, m≤3mm. Specifically, the height difference here may be the height difference between the bottom surface of the abutting wall 23 and the lowest position of the bottom surface of the scraping plate 1.

[0086] The bottom surface of the abutment wall 23 may be higher by m than the bottom surface of the scraper plate 1, or the bottom surface of the abutment wall 23 may be lower by m than the bottom surface of the scraper plate 1; because the thickness of the sewage scraped off by the scraper plate 1 is limited, if the height difference m between the bottom surface of the abutment wall 23 and the bottom surface of the scraper plate 1 is large, the sewage gathered together cannot reach the height of the height difference, and thus cannot be guided away by the abutment wall 23, and further cannot be guided to the sewage collecting tank 300 through the guide surface 22. Therefore, the height difference m≤3mm can make the guide surface 22 and the abutment wall 23 have a better guiding effect.

[0087] In a specific embodiment, the height difference m between the bottom surface of the abutting wall 23 and the bottom surface of the scraping plate 1 is 3 mm.

[0088] In a further embodiment, the bottom surface of the abutting wall 23 is not lower than the lowest point 25 of the dirt scraping plate 1 , so as to prevent the flow guide member 2 from scraping the mop 100 first.

[0089] In one embodiment, a height difference n between a connection point between the guide surface 22 and the abutting wall 23 and a lowest point 25 of the guide surface 22 satisfies 1 mm ≤ n ≤ 8 mm.

[0090] When the height difference is too small, the diversion effect is poor and the sewage is easy to overflow. When the height difference is too large, a large space is occupied and it is easy to penetrate into the sewage collection tank 300. When the water level of the sewage collection tank 300 is high, it is easy to cause reverse overflow.

[0091] In a specific embodiment, a height difference n between a connection point between the guide surface 22 and the abutting wall 23 and a lowest point 25 of the guide surface 22 is 1 mm.

[0092] In another specific embodiment, a height difference n between a connection point between the guide surface 22 and the abutting wall 23 and a lowest point 25 of the guide surface 22 is 8 mm.

[0093] In one embodiment, the outer side surface of the scraper plate 1 in the length direction is the first side surface 12, and the distance P between the lowest point 25 of the guide surface 22 and the first side surface 12 in the length direction satisfies P≥3mm.

[0094] The lowest point 25 of the guide surface 22 is guided toward the middle position of the scraper plate 1 to prevent excessive sewage from accumulating on the guide surface and still overflowing.

[0095] In a specific embodiment, the outer side surface of the scraper plate 1 in the length direction is the first side surface 12, and the distance P between the lowest point 25 of the guide surface 22 and the first side surface 12 in the length direction is 3 mm.

[0096] In one embodiment, the scraping plate 1 is provided with the scraping edges 11 on both sides in the width direction, and the guide member 2 is provided with the abutting wall 23 and the guide wall 24 on both sides in the width direction, respectively.

[0097] The scraper 1 is provided with scraping edges 11 on both sides in the width direction, and can scrape the two mops 100 arranged on both sides in the width direction of the scraper 1, respectively. The guide member 2 is provided with the abutting wall 23 and the guide wall 24 on both sides in the width direction, respectively, and can guide the sewage scraped by the two scraping edges 11 on both sides in the length direction, and guide it to fall into the sewage collection tank 300, effectively guiding the water on both sides in the length direction of the scraper 1, and can avoid water leakage on both sides of the mop 100 when mopping the floor, so as to achieve uniform water stains on the ground when mopping the floor, greatly improve the cleaning effect, and avoid the potential damage to the floor caused by serious water stains on both sides of the mop 100. The guide member 2 is provided with the abutting wall 23 and the guide wall 24 on both sides in the width direction, respectively, which can prevent the water from overflowing to the mop 100 on the other side when there is more water on one side of the mop 100.

[0098] As a convertible embodiment, the scraping plate 1 may be provided with the scraping edge 11 on both sides in the width direction, the guide member 2 may be provided with the abutment walls 23 on both sides in the width direction, and the two abutment walls 23 may be connected to one guide wall 24 .

[0099] In one embodiment, the outer side surface of the scraper plate 1 in the length direction includes two outer wall surfaces arranged in a stepped shape, and the two abutting walls 23 of the guide member 2 are respectively arranged close to the two outer wall surfaces.

[0100] The two abutting walls 23 of the guide member 2 are respectively arranged close to the two outer wall surfaces, which can adapt to mops 100 of different lengths and better guide the sewage on both sides of the length direction of each mop 100.

[0101] In one embodiment, the guide wall 24 includes a guide section 241 and a transition section 242 connected in sequence, the guide section 241 is connected to the abutment wall 23, and the lowest point 25 of the guide surface 22 is set on the transition section 242; the two guide sections 241 of the guide member 2 are arranged at intervals, and the two transition sections 242 are connected to form a transition section.

[0102] The two transition sections 242 are connected to form a transition portion, and the strength of the two guide arms can be enhanced by setting the transition portion.
