Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a cleaning device and cleaning equipment. Background Technology

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, cleaning equipment with vacuuming and mopping functions typically cleans the floor using a squeegee. This equipment usually also has an air intake that sucks in water stains and debris, working in conjunction with the squeegee to clean the floor. As the cleaning equipment moves, the squeegee bends to one side and scrapes the floor. Furthermore, as the cleaning direction changes when the equipment is dragged back and forth, the squeegee changes its bending direction.

[0004] However, existing squeegees encounter significant resistance when changing direction, making it difficult to change direction and easily leaving water stains, thus affecting the cleaning effect. Utility Model Content

[0005] This application provides a cleaning device and equipment to solve the technical problem that existing scrapers have high resistance when changing bending direction, making it difficult to change direction and easily causing water stains to remain, thus affecting the cleaning effect.

[0006] In a first aspect, this application provides a cleaning device, which includes a device body and a scraping assembly. The scraping assembly is disposed at the bottom of the device body. The scraping assembly includes a scraping element. When the cleaning device cleans the surface to be cleaned, the scraping element contacts the surface to be cleaned and bends to the side away from the direction of movement of the cleaning device.

[0007] The wiping component includes a wiping body and multiple protrusions. The wiping body extends downward toward the main body of the device. The multiple protrusions are protruding and disposed on one side of the wiping body and are spaced apart along the length of the wiping body. The side of the wiping body opposite to the protrusions has a wiping surface. Along the extension direction of the wiping body, the thickness of the wiping body gradually increases from the lower end of the wiping body to the upper end of the wiping body.

[0008] The cleaning device provided in this application scrapes the surface to be cleaned using a scraping assembly. The scraping component of the scraping assembly can be bent so that its side contacts the surface to be cleaned to increase the scraping area. The side of the scraping body has a protrusion that can scrape off large particles and remove water stains. The main contact part between the scraping body and the surface to be cleaned is the lower end of the scraping body, and the thickness of the scraping body gradually increases from the lower end to the upper end. This makes the lower end of the scraping body thinner, which makes it easier to change the bending direction of the scraping component when the cleaning device changes its direction of movement. It can quickly change from contact between the protrusion and the surface to be cleaned to contact between the water-scraping surface and the surface to be cleaned, thereby reducing water stains caused by the change of bending direction of the scraping component.

[0009] As an optional implementation, the squeegee body has a connecting surface, and multiple protrusions are connected to the connecting surface; when the squeegee is in its natural state, the connecting surface is perpendicular to the horizontal direction, and the squeegee surface forms an angle with the surface to be cleaned.

[0010] This setting allows for variations in the thickness of the scraping surface.

[0011] As an alternative implementation, the lower end of the protrusion in the vertical direction is flush with the lower end of the scraping body.

[0012] This design ensures that when the scraper bends towards the raised part, the raised part can promptly come into contact with the surface to be cleaned.

[0013] As an optional implementation, the wiping body has a connecting surface, and when the wiping component is in its natural state, both the connecting surface and the wiping surface form an angle with the horizontal direction.

[0014] This setting allows for variations in the thickness of the scraping surface.

[0015] As an optional implementation, when the squeegee is perpendicular to the surface to be cleaned, the angle between the squeegee surface and the surface to be cleaned is greater than 0° and less than 90°.

[0016] This setting allows for adjustment of the curvature of the wiper surface, ensuring wiping power while making the wiper surface bend more smoothly.

[0017] As an optional implementation, the scraping assembly also includes a connector, which includes a horizontal connecting section and a vertical connecting section. The horizontal connecting section is connected to the main body of the device, the upper end of the vertical connecting section is connected to the horizontal connecting section, and the lower end of the vertical connecting section is connected to the upper end of the scraping main body.

[0018] This design improves the structural stability of the scraping assembly.

[0019] As an optional implementation, the wall thickness of the lower end of the scraping body is greater than or equal to 0.3 mm and less than or equal to 1 mm.

[0020] This design, by limiting the wall thickness at the lower end of the squeegee body, makes the lower end of the squeegee body bend more smoothly and prevents water from splashing.

[0021] As an optional implementation, the wall thickness of the lower end of the scraping body is 0.5 mm.

[0022] With this design, by limiting the wall thickness at the lower end of the wiping body, the wiping effect of the wiping component is better, and water splashes will not be caused.

[0023] As an optional implementation, the protrusions are arranged at intervals along the length of the scraping body; the cross-sectional width of the top of the protrusion relative to the scraping body is smaller than the cross-sectional area of ​​the bottom end of the protrusion connected to the scraping body.

[0024] With this design, the protrusions can form water passages to allow water stains to pass through.

[0025] As an optional implementation, the main body of the device has a suction channel and a suction port, the suction port facing downwards and communicating with the suction channel; along the cleaning direction of the cleaning device, at least one of the front and rear sides of the suction port is provided with a scraping component; the side of the scraping component with the protrusion faces away from the suction port.

[0026] With this design, the air intake can draw in water stains that have passed through the scraper, improving the cleaning effect.

[0027] Secondly, this application provides a cleaning device, which includes a main body and the aforementioned cleaning device, wherein the cleaning device is movably connected to the main body.

[0028] This application provides a cleaning device and equipment. The cleaning device includes a main body and a scraping assembly, with the scraping assembly disposed at the bottom of the main body. The scraping assembly includes a scraper. When the cleaning device cleans the surface to be cleaned, the scraper contacts the surface and bends towards a side opposite to the direction of movement of the cleaning device. The scraper includes a scraping body and multiple protrusions. The scraping body extends downward toward the main body, and the multiple protrusions protrude from the sides of the scraping body. Along the extension direction of the scraping body, the thickness of the scraping body gradually increases from the lower end to the upper end. When the cleaning device provided by this application changes its direction of movement, the scraper experiences less resistance when changing its bending direction, allowing for timely reversal to prevent water stains from remaining.

Therefore, they should not be construed as limitations on this application.

[0050] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0051] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0054] In related technologies, cleaning equipment with vacuuming and mopping functions typically cleans the floor using a squeegee. This equipment usually also has an air intake that sucks in water stains and debris, working in conjunction with the squeegee to clean the floor. As the cleaning equipment moves, the squeegee bends to one side and scrapes the floor. Furthermore, as the cleaning direction changes when the equipment is dragged back and forth, the squeegee changes its bending direction.

[0055] However, the existing scraper blades are relatively thick, which can easily cause the equipment to jump when changing the bending direction. They also have greater resistance to change direction, making it difficult to change direction. This requires dragging one end of the scraper blade to complete the change, resulting in water stains and affecting the cleaning effect.

[0056] To address the aforementioned technical problems, this application provides a cleaning device and a cleaning equipment. The scraping component of the cleaning device cleans the surface to be cleaned using a scraping element. The scraping element includes a scraping body and a protrusion. When the cleaning device moves, the scraping surface of the scraping body or the protrusion can contact the surface to be cleaned and scrape it. The main contact part between the scraping body and the surface to be cleaned is the lower end of the scraping body. The thickness of the scraping body gradually increases from the lower end to the upper end. This results in a smaller thickness at the lower end of the scraping body, making it easier to change the bending direction of the scraping element when the cleaning device changes its moving direction, thereby reducing water stains caused by the change in the bending direction of the scraping element.

[0057] The following section provides examples illustrating the application scenarios of the cleaning devices and equipment provided in the embodiments of this application.

[0058] The cleaning device provided in this application embodiment is applied in a cleaning equipment and is a cleaning structure in the cleaning equipment that comes into contact with the surface to be cleaned. The product type of the cleaning equipment in this application embodiment may include, but is not limited to, vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. Depending on the different product types, the cleaning equipment provided in this application embodiment can be used to clean various types of floors and other surfaces. This application embodiment does not make any specific limitations in this regard.

[0059] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 This is a schematic diagram of the cleaning device provided in the embodiments of this application; Figure 3 A bottom schematic diagram of the cleaning device provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the first scraping component provided in an embodiment of this application; Figure 5 for Figure 4 Sectional view of AA in the middle; Figure 6 for Figure 4 A magnified view of part B in the middle section; Figure 7 A side view of the first scraping assembly provided in an embodiment of this application; Figure 8 This is a schematic diagram of the structure of the second scraping assembly provided in an embodiment of this application; Figure 9 for Figure 8 CC section view; Figure 10 A side view of the second scraping assembly provided in an embodiment of this application.

[0060] See Figures 1 to 10 As shown, this application provides a cleaning device 10, including a device body 100 and a scraping assembly 200. The scraping assembly 200 is disposed at the bottom of the device body 100. The scraping assembly 200 includes a scraping element 210. When the cleaning device 10 cleans the surface to be cleaned, the scraping element 210 contacts the surface to be cleaned and bends to the side away from the moving direction of the cleaning device 10.

[0061] It should be noted that the scraper 210, in its natural state (i.e., without deformation), makes interference contact with the surface to be cleaned. The interference amount can be 0.5-3mm, meaning that in its natural state, the height difference between the lower edge of the scraper 210 and the lower edge of the roller of the device body 100 is 0.5-3mm. Preferably, the interference amount is 1.2mm. In this case, the scraper 210 has a good scraping effect without causing excessive resistance when the cleaning device 10 moves. Because the scraper 210 makes interference contact with the surface to be cleaned, when the cleaning device 10 moves over the surface, the scraper 210 can bend to the side opposite to the direction of movement of the cleaning device 10, with one side of the scraper 210 contacting the surface to be cleaned. This increases the contact area between the scraper 210 and the surface to be cleaned, thus achieving a better scraping effect.

[0062] The scraping component 210 includes a scraping body 211 and a plurality of protrusions 212. The scraping body 211 extends downward toward the device body 100. The plurality of protrusions 212 are provided on one side of the scraping body 211 and are arranged at intervals along the length direction of the scraping body 211. The side of the scraping body 211 away from the protrusions 212 has a wiping surface 211b. Along the extension direction of the scraping body 211, the thickness of the scraping body 211 gradually increases from the lower end of the scraping body 211 to the upper end of the scraping body 211.

[0063] In this embodiment, the scraping body 211 is a component that contacts the surface to be cleaned. The length direction of the scraping body 211 is the width direction of the cleaning device 10. Multiple protrusions are arranged at intervals along the length direction of the scraping body 211, and the multiple protrusions are disposed on one side of the thickness direction of the scraping body 211. Since the scraping body 211 extends downward from the device body 100, and the thickness of the scraping body 211 gradually increases from the lower end to the upper end of the scraping body 211, the lower end of the scraping body 211 is relatively narrow. When the cleaning device 10 moves on the surface to be cleaned and changes its direction of movement, the bending direction of the scraping body 211 will also change accordingly. Because the lower end of the scraping body 211 is relatively narrow, the bending direction of the scraping body 211 changes more promptly, thereby improving the problem of water stain residue.

[0064] As one possible implementation, the wiping body 211 also has a connecting surface 211a, and multiple protrusions 212 are connected to the connecting surface 211a; when the wiping member 210 is in its natural state, the connecting surface 211a is perpendicular to the horizontal direction, and the wiping surface 211b forms an angle with the horizontal direction.

[0065] It should be noted that since the thickness of the scraping body 211 gradually increases from the bottom to the top, at least one of the two sides of the scraping body 211 in the thickness direction, namely the connecting surface 211a and the wiping surface 211b, forms an angle with the vertical direction or changes in a stepped manner, so that the thickness of the scraping body 211 can gradually change.

[0066] In some embodiments, when the squeegee 210 is in its natural state, the connecting surface 211a is perpendicular to the horizontal direction, and the squeegee surface 211b forms an angle with the horizontal direction. This angle is acute, so that the thickness of the lower end of the squeegee body 211 is less than the thickness of the upper end.

[0067] It should be noted that the natural state of the scraper 210 is when the cleaning device 10 is placed on the surface to be cleaned and is not bent.

[0068] In other embodiments, when the squeegee 210 is in its natural state, both the connecting surface 211a and the squeegee surface 211b form an angle with the horizontal direction, and both angles are acute, so that the thickness of the lower end of the squeegee body 211 is less than the thickness of the upper end.

[0069] It should be noted that the lower end of the protrusion in the vertical direction is flush with the lower end of the scraper body. This allows the protrusion to come into contact with the surface to be cleaned in time when the scraper bends to one side, forming a water passage.

[0070] Reference Figure 5 and Figure 9In the above embodiment, when the squeegee 210 is in its natural state, the angle between the squeegee surface 211b and the surface to be cleaned is α, where α is greater than 0° and less than 90°.

[0071] For example, the angle formed between the wiping surface 211b and the surface to be cleaned can be 1°, 10°, 20°, 50°, 89°, etc., and this application embodiment does not make specific limitations.

[0072] To ensure the scraping effect of the scraping component 210 and reduce the pushing and pulling resistance when the cleaning device 10 changes its moving direction, the angle formed between the scraping surface 211b and the surface to be cleaned can be further limited to greater than 60° and less than 90°.

[0073] As one possible implementation, the scraping assembly 200 also includes a connector 240, which includes a horizontal connecting section 241 and a vertical connecting section 242. The horizontal connecting section 241 is connected to the device body 100, the upper end of the vertical connecting section 242 is connected to the horizontal connecting section 241, and the lower end of the vertical connecting section 242 is connected to the upper end of the scraping body 211.

[0074] It should be noted that at least one of the connections between the connector 240 and the device body 100, and between the connector 240 and the scraping body 211, is detachably connected to facilitate the replacement of worn scraping parts 210. The upper end of the scraping body 211 has the same thickness as the vertical connecting section 242.

[0075] Continue to refer to Figure 5 and Figure 9 As one possible implementation, the wall thickness of the lower end of the scraping body 211 is d, which is greater than or equal to 0.3 mm and less than or equal to 1 mm.

[0076] It should be noted that when the wall thickness of the lower end of the scraping body 211 is greater than or equal to 0.3 mm and less than or equal to 1 mm, the wall thickness of the lower end of the scraping body 211 is relatively thin, which makes it easier for the scraping body 211 to change the bending direction and improve the water stains on the surface to be cleaned.

[0077] For example, the wall thickness of the lower end of the scraping body 211 can be 0.3mm, 0.4mm, 0.5mm, 0.7mm, 1mm, etc., and this application embodiment does not make specific limitations.

[0078] Reference Figure 2 and Figure 3 The direction of movement of the cleaning device 10 during cleaning is defined as the X direction, and the width direction of the cleaning device 10 is defined as the Y direction, which is perpendicular to the X direction.

[0079] As one possible implementation, the protrusions 212 are arranged at intervals along the length direction of the scraping body 211, wherein the length direction of the scraping body 211 is the width direction of the cleaning device 10; the cross-sectional width of the top of the protrusion 212 relative to the scraping body 211 is smaller than the cross-sectional area of ​​the bottom end of the protrusion 212 connected to the scraping body 211.

[0080] It should be noted that when the scraper 210 is bent, the protrusion 212 abuts against the surface to be cleaned. The top of the protrusion 212 relative to the top of the scraper body 211 is the abutting end. When the protrusion 212 abuts against the surface to be cleaned, the abutting end contacts the surface line to be cleaned.

[0081] The upper and lower ends of the protrusion 212 are the two ends of the protrusion 212 extending in the vertical direction; the bottom and top ends of the protrusion 212 are the two ends of the protrusion direction of the protrusion 212, that is, the bottom end of the protrusion 212 is the end connected to the scraping body 211, and the top end of the protrusion 212 is the end away from the scraping body 211.

[0082] In some embodiments, the cross-sectional width of the protrusion 212 gradually increases from its top to its bottom where it connects to the scraping body 211. This gradually changing cross-sectional width improves the overall strength of the protrusion 212, and the cross-sectional width is greatest at the connection point between the protrusion 212 and the scraping body 211, thus enhancing connection stability. The protrusion 212 and the scraping body 211 can be connected by bonding, riveting, or other methods, or they can be integrally formed.

[0083] In some embodiments, the cross-sectional shape of the protrusion 212 can be triangular or arc-shaped. The cross-sectional width of the bottom end of the protrusion 212 connected to the scraping body 211 is L, which is greater than or equal to 0.5 mm and less than or equal to 3 mm. Multiple protrusions 212 can be arranged in parallel to each other. The distance between adjacent protrusions 212 is greater than 0 mm and less than or equal to 15 mm. When the protrusion 212 abuts against the surface to be cleaned, a water passage is formed between two adjacent protrusions 212 that allows water stains to pass through.

[0084] The upper end of the protrusion 212 in the extending direction can be spaced from or connected to the scraping body 211. The upper end of the protrusion 212 can be set horizontally or inclined.

[0085] As one possible implementation, the device body 100 has a suction channel 120 and a suction port 110, the suction port 110 facing downward of the device body 100 and communicating with the suction channel 120; along the cleaning direction of the cleaning device 10, at least one of the front and rear sides of the suction port 110 is provided with a scraping component 200; the side of the scraping component 210 with the protrusion 212 faces away from the suction port 110.

[0086] The scraping component 200 can be set with only one set or two sets, and the main body 100 of the device can be equipped with a roller brush or not.

[0087] In this embodiment of the application, the scraping assembly 200 includes a first scraping assembly 220 and a second scraping assembly 230. Along the cleaning direction of the cleaning device 10, the first scraping assembly 220 is located in front of the air intake 110, and the second scraping assembly 230 is located behind the air intake 110. When the cleaning device 10 moves on the surface to be cleaned, the bending directions of the first scraping assembly 220 and the second scraping assembly 230 are the same. When the cleaning device 10 moves forward, the cleaning components of the first scraping assembly 220 and the second scraping assembly 230 bend backward simultaneously. The protrusion 212 of the first scraping assembly 220 contacts the surface to be cleaned, and the wiping surface 211b of the second scraping assembly 230 contacts the surface to be cleaned. The water stains on the surface to be cleaned first pass through the water passage between the protrusion 212 of the first scraping assembly 220 and the surface to be cleaned, and reach the bottom of the air intake 110. Some of the water stains enter the air intake 110 under the suction force of the air intake 110. The remaining water stains, blocked by the wiping surface 211b of the second scraping assembly 230, will gather on the front side of the second scraping assembly 230 and be sucked in by the air intake 110.

[0088] Similarly, along the cleaning direction of the cleaning device 10, when the cleaning device 10 is pulled back, the scraping parts 210 of the first scraping assembly 220 and the second scraping assembly 230 simultaneously bend forward. The protrusion 212 of the second scraping assembly 230 contacts the surface to be cleaned, and the wiping surface 211b of the first scraping assembly 220 contacts the surface to be cleaned. The water stains on the surface to be cleaned first pass through the water passage between the protrusion 212 of the second scraping assembly 230 and the surface to be cleaned, reaching below the air intake 110. Some of the water stains enter the air intake 110 under the suction force of the air intake 110, while the remaining water stains, blocked by the wiping surface 211b of the first scraping assembly 220, will accumulate on the front side of the second scraping assembly 230 and be sucked in by the air intake 110. In this way, whether the cleaning device 10 moves forward or backward, the water stains can be removed and the cleaning is completed by the two scraping assemblies 200 working in conjunction with the air intake 110.

[0089] In this embodiment of the application, the main body 100 of the device is further provided with a water spraying component 300, which is disposed between the first scraping component 220 and the second scraping component 230. The water spraying component 300 is used to spray cleaning water onto the surface to be cleaned.

[0090] Understandably, relying solely on the combination of the scraping component 200 and the suction port 110 results in limited cleaning effectiveness, and stubborn stains are easily left on the surface to be cleaned. The water spray component 300 sprays cleaning water onto the surface to be cleaned, which can rinse and wet the surface. Then, the scraping component 200 scrapes the surface, and the wastewater after scraping is sucked in by the suction port. This allows the cleaning device 10 to still achieve a good cleaning effect even without the roller brush.

[0091] It should be noted that the first scraping assembly 220 and the second scraping assembly 230 can form a closed cleaning cavity with the two side walls in the width direction of the device body 100, so that the cleaning water sprayed by the water spray assembly 300 will not splash into the surrounding environment. The water spray assembly 300 is provided with a plurality of water spray holes 310, which are arranged at intervals along the width direction of the device body 100, and the plurality of water spray holes 310 can spray cleaning water onto the surface to be cleaned.

[0092] For example, the water spray assembly 300 has two water spray holes 310 located at both ends of the water spray assembly 300 along the width direction of the device body 100, and the air intake 110 located in the middle of the width direction of the device body 100. When the water spray assembly 300 sprays water, the water flow will first spray onto the surface to be cleaned, and then, under the influence of suction, the water flow will move towards the middle air intake 110. During the process of the water flow moving towards the middle air intake 110 on the surface to be cleaned, the surface to be cleaned can be wetted.

[0093] In some embodiments, the air intake 110 may include a first intake 111, a second intake 112, and a third intake 113. Along the cleaning direction of the cleaning device 10, the first intake 111 is located in front of the first scraping assembly 220, the second intake 112 is located between the first scraping assembly 220 and the water spray assembly 300, and the third intake 113 is located between the water spray assembly 300 and the second scraping assembly 230. When the water spray assembly 300 sprays water, the second intake 112 and the third intake 113 can recover the cleaning water sprayed by the water spray assembly 300. Along the cleaning direction of the cleaning device 10, when the cleaning device 10 moves forward, the second intake 112 can suck in some wastewater, and the wastewater accumulated in front of the second scraping assembly 230 is sucked in by the third intake 113; when the cleaning device 10 is pulled backward, the third intake 113 can suck in some wastewater, and the wastewater accumulated in front of the first scraping assembly 220 is sucked in by the second intake 112.

[0094] It should be noted that the first suction port 111 and the second suction port 112 are separated by the first scraping assembly 220. The diameter of the first suction port 111 can be larger than the diameter of the second suction port 112, so that when the cleaning device 10 moves forward in the cleaning direction, the first suction port 111 can suck in large particles of debris. The top of the first scraping assembly 220 is provided with a ventilation notch 221, which connects the first suction port 111 and the second suction port 112. This allows some debris to be sucked in by the second suction port 112 through the ventilation notch 221, improving cleaning efficiency.

[0095] This application also provides a cleaning device 1, which includes a main body 20 and the aforementioned cleaning device 10, with the cleaning device 10 movably connected to the main body 20. The top of the main body 20 may be equipped with a handle for easy gripping by cleaning personnel. The main body 20 of the cleaning device 1 is equipped with a cleaning water tank and a water pump, the water pump being connected to the cleaning water tank and configured to provide cleaning water to the spray assembly 300. With a fixed cleaning water tank capacity, the water pump can control the water output of the spray assembly 300, ensuring a continuous and uninterrupted spray of cleaning water during the cleaning process. The main body 20 may also be equipped with a wastewater tank, which is connected to a suction channel 120. After the suction port 110 draws in the cleaning wastewater, it can be carried by the airflow conveyor belt through the suction channel 120 into the wastewater tank for recycling.

[0096] This application provides a cleaning device 10 and a cleaning equipment 1. The cleaning device 10 includes a device body 100 and a scraping assembly 200. The scraping assembly 200 is disposed at the bottom of the device body 100. The scraping assembly 200 includes a scraper 210. When the cleaning device 10 cleans the surface to be cleaned, the scraper 210 contacts the surface to be cleaned and bends to the side away from the moving direction of the cleaning device 10. The scraper 210 includes a scraping body 211 and a plurality of protrusions 212. The scraping body 211 extends downward toward the device body 100, and the plurality of protrusions 212 protrude from the side of the scraping body 211. Along the extending direction of the scraping body 211, the thickness of the scraping body 211 gradually increases from the lower end to the upper end of the scraping body 211. When the cleaning device 10 provided by this application changes its moving direction, the scraper 210 experiences less resistance when changing its bending direction, and can change direction in a timely manner to prevent water stains from remaining.
