Abstract
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 that extends downward toward the device body. When the cleaning device cleans the surface to be cleaned, the scraping element bends toward a side away from the direction of movement of the cleaning device.
[0007] The squeegee includes a squeegee body and multiple protrusions. The multiple protrusions protrude from one side of the squeegee body and are arranged at intervals along the length of the squeegee body. The protrusions extend vertically, and the side of the squeegee body opposite to the protrusions has a squeegee surface. Along the extension direction of the protrusions, the protrusion height at the upper end of the protrusion is less than the protrusion height at the lower end of the protrusion.
[0008] When the cleaning device provided in this application moves, the scraper can be bent to one side so that the scraping surface or protrusion comes into contact with the surface to be cleaned, thereby scraping the surface to be cleaned. When the protrusion comes into contact with the surface to be cleaned, the lower end of the protrusion is the main contact part with the surface to be cleaned. The lower end of the protrusion has a larger protrusion height so that the protrusion can fully contact the surface to be cleaned. The upper end of the protrusion has a smaller protrusion height so that the overall thickness of the scraper can be reduced. This makes it easier to change the bending direction of the scraper when the cleaning device changes its moving direction, thereby reducing water stains caused by the change of bending direction of the scraper.
[0009] As an alternative implementation, the protrusion height of the protrusion gradually decreases from the lower end to the upper end of the protrusion.
[0010] This design makes the structure of the protrusion smoother, reducing scratch resistance.
[0011] As an optional implementation, the protrusion includes a first protrusion and a second protrusion. Along the extending direction of the protrusion, the first protrusion is located below the second protrusion, and the upper end of the first protrusion and the lower end of the second protrusion are connected.
[0012] This design allows for different functions to be achieved through the two protrusions, thus improving the cleaning effect.
[0013] As an alternative implementation, the protrusion height of the first protrusion remains constant from the lower end to the upper end of the protrusion, while the protrusion height of the second protrusion gradually decreases.
[0014] With this design, the first protrusion can scrape the surface to be cleaned, and the second protrusion can reduce the overall thickness of the scraper, making it easier for the scraper to change its bending direction.
[0015] As an optional implementation, the length of the first protrusion is 1 mm along the extending direction of the protrusion.
[0016] With this design, when the scraper bends, the first protrusion can maintain sufficient contact length with the surface to be cleaned, thus ensuring the cleaning effect.
[0017] As an optional implementation, along the extending direction of the protrusion, the protrusion height of the lower end of the second protrusion is the same as the protrusion height of the first protrusion.
[0018] This design allows the first and second protrusions to connect smoothly, reducing scratching resistance.
[0019] As an optional implementation, the scraping assembly includes a connector connected to the device body, a first end of the scraping body connected to the connector, and a second end of the scraping body disposed facing downward toward the device body; the thickness of the first end of the scraping body is greater than the thickness of the second end of the scraping body.
[0020] Along the extending direction of the protrusion, the lower end of the first protrusion is flush with the second end of the scraping body; the upper end of the second protrusion is spaced from the first end of the scraping body, or the upper end of the second protrusion is connected to the first end of the scraping body.
[0021] This design improves the connection stability between the scraping component and the main body of the device through the connector.
[0022] As an alternative implementation, the bottom end of the protrusion is connected to the side of the scraping body, and the top end of the protrusion protrudes to the side away from the scraping body; from the bottom end of the protrusion to the top end of the protrusion, the cross-sectional width of the protrusion gradually decreases.
[0023] Along the extending direction of the protrusion, the width of the connection surface between the bottom end of the protrusion and the scraping body remains unchanged.
[0024] This design improves the connection stability between the protrusion and the scraping body by keeping the width of the connection surface between the bottom of the protrusion and the scraping body constant.
[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 cleaning 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 extending downwards from the main body. When the cleaning device cleans the surface to be cleaned, the scraper bends to a side opposite to the direction of movement of the cleaning device. The scraper includes a scraping body and multiple protrusions, which protrude from the side of the scraping body and extend vertically. Along the extension direction of the protrusions, the height of the upper end of the protrusion is less than the height of the lower 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.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

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 turning resistance and are difficult to change direction. As a result, the scraper blades need to be dragged a distance to complete the turning, which leaves water stains and affects the cleaning effect.
[0056] To address the aforementioned technical problems, this application provides a cleaning device and cleaning equipment. The scraping component of the cleaning device cleans the surface to be cleaned using a scraper. The scraper includes a scraping body and a protrusion. When the cleaning device moves, the scraper bends, causing the scraping surface of the scraping body or the protrusion to contact the surface to be cleaned. When the protrusion contacts the surface to be cleaned, its lower end mainly abuts against the surface. Since the lower end of the protrusion has a larger protrusion height and the upper end has a smaller protrusion height, it can ensure that the protrusion makes full contact with the surface to be cleaned while reducing the overall thickness of the scraper. This makes it easier for the scraper to change its bending direction, thereby reducing water stains caused by the change in the bending direction of the scraper.
[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, which 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 scraping member 210, which extends downward toward the device body 100. When the cleaning device 10 cleans the surface to be cleaned, the scraping member 210 bends toward a 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 plurality of protrusions 212 are protruding from one side of the scraping body 211 and are arranged at intervals along the length direction of the scraping body 211. The protrusions 212 extend vertically. The side of the scraping body 211 opposite to the protrusions 212 has a wiping surface 213. Along the extending direction of the protrusions 212, the protrusion height at the upper end of the protrusion 212 is less than the protrusion height at the lower end of the protrusion 212.
[0063] It is understandable that the protrusion height of the protrusion 212 is the vertical distance between the top of the protrusion 212 and the scraping body 211. When the protrusion 212 comes into contact with the surface to be cleaned, the lower end of the protrusion 212 is the main contact part with the surface to be cleaned. Since the lower end of the protrusion 212 has a larger protrusion height and the upper end has a smaller protrusion height, the scraping effect of the protrusion 212 can be guaranteed while reducing the overall thickness of the scraping part 210, thereby making it easier for the scraping part 210 to change the bending direction.
[0064] In some embodiments, from the lower end to the upper end of the protrusion 212, the protrusion height of the protrusion 212 gradually decreases smoothly, the top of the protrusion 212 is in line contact with the surface to be cleaned, and the top of the protrusion 212 is a smooth curve.
[0065] In some embodiments, from the lower end to the upper end of the protrusion 212, the protrusion height of the protrusion 212 gradually decreases in a stepped manner, and the top of the protrusion 212 is in line contact with the surface to be cleaned, with the top of the protrusion 212 changing in a stepped manner.
[0066] It should be noted that 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.
[0067] In this embodiment, the protrusion 212 includes a first protrusion 212a and a second protrusion 212b. Along the extending direction of the protrusion 212, the first protrusion 212a is located below the second protrusion 212b, and the upper end of the first protrusion 212a and the lower end of the second protrusion 212b are connected. The first protrusion 212a and the second protrusion 212b can be integrally formed, or they can be bonded or detachably connected.
[0068] As one possible implementation, from the lower end of the protrusion 212 to the upper end of the protrusion 212, the protrusion height of the first protrusion 212a remains constant, while the protrusion height of the second protrusion 212b gradually decreases.
[0069] Understandably, when the protrusion 212 abuts against the surface to be cleaned, if the interference fit of the scraper 210 is small or moderate, it is mainly the first protrusion 212a that contacts the surface to be cleaned. To ensure the scraping effect, the height of the first protrusion 212a can be kept constant. At the same time, in order to make it easier for the scraper 210 to change its bending direction when the cleaning device 10 changes its moving direction, the overall thickness of the upper end of the scraper 210 can be reduced by gradually decreasing the protrusion height of the second protrusion 212b. The protrusion height of the second protrusion 212b can decrease smoothly or in a stepped manner.
[0070] In this embodiment of the application, along the extending direction of the protrusion 212, the length of the first protrusion 212a is 1mm, and the interference between the scraper 210 and the surface to be cleaned is 1.2mm. At this time, the first protrusion 212a can fully contact the surface to be cleaned, ensuring the cleaning effect, while minimizing the overall thickness of the scraper 210.
[0071] In particular, along the extending direction of the protrusion 212, the protrusion height of the lower end of the second protrusion 212b is the same as the protrusion height of the first protrusion 212a, so that the connection between the first protrusion 212a and the second protrusion 212b can be smoothly transitioned.
[0072] As one possible implementation, the scraping assembly 200 also includes a connector 240 connected to the device body 100, with a first end of the scraping body 211 connected to the connector 240 and a second end of the scraping body 211 disposed facing downward toward the device body 100.
[0073] It should be noted that the connection between the connector 240 and the device body 100, and between the connector 240 and the first end of the scraping body 211, can both be detachably connected, or at least one of them can be detachably connected. This arrangement facilitates the replacement of worn scraping parts 210.
[0074] It should be noted that the first end of the scraping body 211 is the connecting segment 211a, and the second end of the scraping body 211 is the flexible segment 211b. The thickness of the flexible segment 211b is less than the thickness of the connecting segment 211a. When the scraping body 211 is bent, it is mainly the flexible segment 211b that bends.
[0075] In this embodiment of the application, the bottom plane of the connecting segment 211a can be set horizontally or inclined; the thickness of the flexible segment 211b gradually increases from the end near the surface to be cleaned to the end near the connecting segment 211a, making it easier for the flexible segment 211b to change the bending direction. The thickness of the end of the flexible segment 211b near the surface to be cleaned is d, where d is greater than or equal to 0.3mm and less than or equal to 1mm.
[0076] For example, the thickness of the end of the flexible segment 211b near the surface to be cleaned can be 0.3mm, 0.4mm, 0.5mm, 0.7mm, 1mm, etc., and this application embodiment does not make specific limitations.
[0077] It should be noted that the protrusion 212 is disposed on the side of the flexible section 211b. Along the extending direction of the protrusion 212, the lower end of the first protrusion 212a is flush with the second end of the scraping body 211; the upper end of the second protrusion 212b is spaced from the connecting section 211a, or the upper end of the second protrusion 212b is connected to the connecting section 211a.
[0078] As one possible implementation, the bottom end of the protrusion 212 is connected to the side of the scraping body 211, and the top end of the protrusion 212 protrudes to the side away from the scraping body 211; from the bottom end of the protrusion 212 to the top end of the protrusion 212, the cross-sectional width of the protrusion 212 gradually decreases.
[0079] In this embodiment of the application, the cross-sectional shape of the protrusion 212 can be triangular or arc-shaped. When the protrusion 212 abuts against the surface to be cleaned, the top of the protrusion 212 is in line contact with the surface to be cleaned.
[0080] 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.
[0081] In this embodiment, along the extending direction of the protrusion 212, the width of the connection surface between the bottom end of the protrusion 212 and the scraping body 211 remains unchanged. The width of the connection surface between the bottom end of the protrusion 212 and the scraping body 211 is L, which can be greater than or equal to 0.5 mm and less than or equal to 3 mm. Multiple protrusions 212 are arranged at intervals along the length direction of the scraping body 211, that is, at intervals along the width direction of the cleaning device 10. The distance between two adjacent protrusions 212 can be 0-15 mm.
[0082] For example, the width of the connection surface between the bottom end of the protrusion 212 and the scraping body 211 can be 0.5mm, 1mm, 1.2mm, 1.5mm, 2mm, 2.9mm, 3mm, etc., and this application embodiment does not make specific limitations.
[0083] The spacing between adjacent protrusions 212 can be 0.1mm, 1mm, 3mm, 5mm, 10mm, 15mm, etc., and this application embodiment does not make a specific limitation.
[0084] 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.
[0085] 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 flexible sections 211b 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 213 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 of the air intake 110. The remaining water stains are blocked by the wiping surface 213 of the second scraping assembly 230 and will gather on the front side of the second scraping assembly 230 and be sucked in by the air intake 110.
[0086] Similarly, along the cleaning direction of the cleaning device 10, when the cleaning device 10 is pulled back, the flexible sections 211b 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 213 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 213 of the first scraping assembly 220, accumulate on the front side of the second scraping assembly 230 and are 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 cleaning is completed by the two scraping assemblies 200 working in conjunction with the air intake 110.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] 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.
[0093] 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.
[0094] 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, which is disposed at the bottom of the device body 100. The scraping assembly 200 includes a scraper 210 extending downward toward the device body 100. When the cleaning device 10 cleans the surface to be cleaned, the scraper 210 bends toward a side opposite to the moving direction of the cleaning device 10. The scraper 210 includes a scraping body 211 and a plurality of protrusions 212, which protrude from the side of the scraping body 211 and extend vertically. Along the extending direction of the protrusions 212, the protrusion height at the upper end of the protrusion 212 is less than the protrusion height at the lower end of the protrusion 212. 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.
[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
