Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a floor brush 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 maintains a clean and tidy living and working environment through various functions such as vacuuming and scrubbing.

[0003] In related technologies, cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean the floor. The floor brush is equipped with a roller brush and a water tank. The water tank supplies cleaning water to wet the roller brush, and the wet roller brush rolls on the floor to achieve a wet mopping cleaning effect. In addition, a suction port is set on the floor brush to suck up garbage and debris on the floor, as well as wastewater scraped off from the roller brush.

[0004] However, current cleaning equipment often leaves water stains on the cleaned floor after cleaning, resulting in poor cleaning effectiveness. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that current cleaning equipment often leaves water stains on the cleaned floor after cleaning, resulting in poor cleaning effect.

[0006] In a first aspect, this application provides a floor brush device, including a device body and a cleaning component. The device body has a floor brush air duct with an air inlet. The cleaning component is disposed at the air inlet and connected to the device body. The cleaning component has a suction port facing downwards from the device body and is connected to the air inlet.

[0007] The cleaning component includes a scraping component, the lower edge of which is lower than the lower surface of the main body of the device, and when the floor brush device is placed on the surface to be cleaned, the lower edge of the scraping component has an interference fit of 0-5mm with the surface to be cleaned.

[0008] The scraping assembly has a concave and convex surface. When the floor brush device moves on the surface to be cleaned, the lower edge of the scraping assembly bends to the side opposite to the direction of movement so that the concave and convex surface contacts the surface to be cleaned and forms a water passage.

[0009] The floor brush device provided in this application scrapes the surface to be cleaned through a scraping component and sucks up the debris from the surface through a suction port, thereby cleaning the surface. When the floor brush device is cleaning, the lower edge of the scraping component has an interference of 0-5mm with the surface to be cleaned, so that the scraping component has good cleaning power while the frictional resistance between the scraping component and the surface to be cleaned will not affect the normal movement of the floor brush device.

[0010] As an optional implementation, the lower edge of the scraping assembly is arranged in a horizontal or approximately horizontal direction; when the floor brush device moves on the surface to be cleaned, the bending angle of the lower edge of the scraping assembly relative to the vertical direction is equal to or approximately 90°.

[0011] This design allows the lower edge of the scraping component to bend, thereby increasing the contact area between the scraping component and the surface to be cleaned and improving the scraping effect.

[0012] As an optional implementation, the length direction of the scraping component is parallel to the width direction of the device body, and the length dimension of the scraping component matches the width dimension of the device body.

[0013] With this configuration, the swiping area of ​​the swiping component can cover the movement path of the main body of the device, preventing cleaning from being missed.

[0014] As an optional implementation, the uneven surface has multiple protrusions and multiple recesses, which are alternately arranged in sequence along the length of the scraping assembly; when the uneven surface contacts the surface to be cleaned, the protrusions abut against the surface to be cleaned, and a water passage is formed between the recesses and the surface to be cleaned.

[0015] This design allows water stains to enter below the suction port through the water passage and be sucked in, preventing water stains from remaining on the surface to be cleaned.

[0016] As an alternative implementation, the scraping assembly has a flat surface, and along the moving direction of the floor brush device, the concave and convex surfaces are located on the side of the scraping assembly away from the suction port, while the flat surface is located on the side of the scraping assembly facing the suction port.

[0017] This setup allows for squeegeeing by contacting the flat surface with the surface to be cleaned, causing wastewater to collect on the side facing the suction port and be sucked in, thus improving cleaning efficiency.

[0018] As an optional implementation, the scraping assembly includes a mounting body and a flexible scraping member. The mounting body is connected to the device body, the upper part of the flexible scraping member is connected to the mounting body, and the lower part of the flexible scraping assembly extends downward toward the device body, with concave and convex surfaces provided near the lower part of the flexible scraping member.

[0019] With this configuration, the movement of the main body of the device can drive the scraping component to move, causing the flexible scraping part to bend and deform, thereby improving the scraping efficiency.

[0020] As an optional implementation, the scraping assembly includes a first scraping assembly and a second scraping assembly. Along the cleaning direction of the floor brush device, the first scraping assembly is located in front of the suction port, and the second scraping assembly is located behind the suction port. When the floor brush device moves on the surface to be cleaned, the bending directions of the first scraping assembly and the second scraping assembly are the same.

[0021] With this setup, whether the floor brush device moves forward or backward, the first scraping component and the second scraping group can scrape the surface to be cleaned, and work together with the suction port to suck up debris and water stains.

[0022] As an optional implementation, along the cleaning direction of the floor brush device, the concave and convex surfaces of the first scraping component are located on the front side of the first scraping component, and the flat surface of the first scraping component is located on the rear side of the first scraping component; the concave and convex surfaces of the second scraping component are located on the rear side of the second scraping component, and the flat surface of the second scraping component is located on the front side of the second scraping component.

[0023] This design ensures that regardless of whether the floor brush device moves forward or backward, the flat surface of the rear scraping component can contact the surface to be cleaned along the direction of movement of the floor brush device to remove water stains and improve the cleaning effect.

[0024] As an optional implementation, the cleaning assembly also includes a water spraying assembly disposed between the first scraping assembly and the second scraping assembly, the water spraying assembly being configured to spray cleaning water onto the surface to be cleaned.

[0025] The suction port includes a first suction port, a second suction port, and a third suction port. Along the cleaning direction of the floor brush device, the first suction port is located in front of the first scraping assembly, the second suction port is located between the first scraping assembly and the water spray assembly, and the third suction port is located between the water spray assembly and the second scraping assembly.

[0026] With this setup, water spraying from the water spray unit onto the surface to be cleaned softens stains and improves the scraping effect of the scraping unit.

[0027] Secondly, this application provides a cleaning device, which includes a main body and the aforementioned floor brush device. The main body of the cleaning device is provided with a cleaning water tank and a water pump. The water pump is connected to the cleaning water tank and is configured to provide cleaning water to the spray assembly.

[0028] With this setup, water is supplied to the water spray unit via a water pump, ensuring that the water spray unit can continuously spray cleaning water during the cleaning process and guarantee the cleaning effect.

[0029] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body and a cleaning component. The main body has a floor brush air duct with an air inlet. The cleaning component is disposed at the air inlet and connected to the main body. The cleaning component has a suction port facing downwards from the main body and is connected to the air inlet. The cleaning component includes a scraping component. The lower edge of the scraping component is lower than the lower surface of the main body. When the floor brush device is placed on the surface to be cleaned, the lower edge of the scraping component has an interference fit of 0-5mm with the surface to be cleaned. The scraping component also has a concave and convex surface. When the floor brush device moves on the surface to be cleaned, the lower edge of the scraping component bends to the side opposite to the direction of movement, so that the concave and convex surface contacts the surface to be cleaned and forms a water passage. The water passage allows water stains to pass through the scraping component and enter below the suction port, where they are sucked in, preventing water stains from remaining on the surface to be cleaned and providing a better cleaning effect.

[0047] 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.

[0048] Vacuum cleaners, floor scrubbers, and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment maintains a clean and tidy living and working environment through various functions such as vacuuming and scrubbing. Among related technologies, cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean the floor. The floor brush is equipped with a roller brush and a water tank. The water tank supplies cleaning water to wet the roller brush, and the wet roller brush rolls on the floor to achieve a wet mopping cleaning effect. In addition, the floor brush has a suction port that can suck up garbage and debris on the floor, as well as wastewater scraped off by the roller brush.

[0049] Current roller brushes can absorb water and are usually used to clean floors when they are wet to achieve better cleaning results. However, after cleaning, water stains are easily left on the cleaned floor, resulting in poor cleaning effect.

[0050] In addition, after cleaning, the roller brush needs to be washed and dried, which adds a cleaning step. If it is not dried, the roller brush is prone to odor or even mold.

[0051] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The floor brush device includes a scraping component and a suction port. The scraping component has concave and convex surfaces. By limiting the lower edge of the scraping component to have an interference fit of 0-5mm with the ground, the concave and convex surfaces can contact the ground when the floor brush device moves, forming a water passage. The water passage allows water stains to pass through, concentrating them below the suction port. This allows the water stains to be efficiently sucked in from the suction port, preventing water stain residue and improving cleaning efficiency.

[0052] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0053] The floor brush device provided in this application embodiment is applied in 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.

[0055] Reference Figures 1 to 7 As shown, this application provides a floor brush device 100 for use in a cleaning device 10. The floor brush device 100 includes a device body 110 and a cleaning component 120. The device body 110 has a floor brush air duct 111 with an air inlet 1111. The cleaning component 120 is disposed at the air inlet 1111 and connected to the device body 110. The cleaning component 120 has a suction port 121 facing downwards from the device body 110 and communicating with the air inlet 1111. The cleaning component 120 includes a scraping component 122. The lower edge of the scraping component 122 is lower than the lower surface of the device body 110. When the floor brush device 100 is placed on the surface to be cleaned, the lower edge of the scraping component 122 has an interference fit of 0-5mm with the surface to be cleaned.

[0056] It is understood that the main body 110 of the device is equipped with a suction unit. When the floor brush device 100 moves and cleans the surface to be cleaned, the suction unit is activated. The suction unit transmits negative pressure suction to the air inlet 1111 through the floor brush air duct 111, so that the suction port 121 connected to the air inlet 1111 also generates suction. On the one hand, the suction port 121 can directly suck up the garbage and debris on the surface to be cleaned. On the other hand, stubborn stains, sticky garbage and debris and residual water stains that are difficult to suck up on the surface to be cleaned can be scraped off by the scraping component 122. These stubborn stains, sticky garbage and debris and residual water stains will accumulate on the front side of the scraping component 122 in the direction of movement and then be sucked in by the suction port 121. The cooperation between the scraping component 122 and the suction port 121 can achieve the cleaning of the surface to be cleaned.

[0057] It should be noted that when the floor brush device 100 is placed on the surface to be cleaned, the scraping component 122 has an interference of 0-5mm with the surface to be cleaned in its natural state, that is, in the state without deformation. In other words, in its natural state, the height difference between the lower edge of the scraping component 122 and the lower edge of the roller of the device body 110 is 0-5mm.

[0058] When the interference between the lower edge of the scraping component 122 and the surface to be cleaned is 0-5mm, the scraping component 122 has a good scraping effect on the surface to be cleaned, and the pushing and pulling force is good. It will not cause excessive friction between the scraping component 122 and the surface to be cleaned due to excessive pressure from the scraping component 122 on the surface to be cleaned, thus affecting the normal movement of the floor brush device 100.

[0059] For example, the interference is greater than 0 and less than or equal to 5 mm. Specifically, the interference between the lower edge of the scraping component 122 and the surface to be cleaned can be 0.1 mm, 0.5 mm, 1 mm, 3 mm, 4 mm, 5 mm, etc. The embodiments of this application do not make specific limitations.

[0060] As one possible implementation, the scraping assembly 122 has a concave-convex surface 1221. When the floor brush device 100 moves on the surface to be cleaned, the lower edge of the scraping assembly 122 bends to the side opposite to the direction of movement, so that the concave-convex surface 1221 contacts the surface to be cleaned and forms a water passage.

[0061] Understandably, the uneven surface 1221 is located on the side of the scraping assembly 122. When the brush device 100 moves, the lower edge of the scraping assembly 122 bends, so that the uneven surface 1221 contacts the surface to be cleaned. The uneven surface 1221 and the surface to be cleaned can form a narrow water passage to allow water stains to pass through, while large particles of debris cannot pass through and accumulate on the front side of the scraping assembly 122.

[0062] It should be noted that the size of the interference fit between the lower edge of the scraping assembly 122 and the surface to be cleaned affects the water flow capacity of the water passage. When the scraping assembly 122 contacts the surface to be cleaned, as the floor brush device 100 moves over the surface, the lower edge of the scraping assembly 122 bends, causing the concave-convex surface 1221 to contact the surface. As the interference fit of the scraping assembly 122 decreases and the angle formed between the concave-convex surface 1221 and the surface to be cleaned gradually increases, eventually approaching 90°, the water passage formed between the concave-convex surface 1221 and the surface to be cleaned gradually shrinks as the machine moves, resulting in a weakened water flow capacity. If the interference fit is too large, the pressure exerted by the scraping assembly 122 on the surface to be cleaned will increase, leading to increased friction and affecting the user experience. When the pressure exerted by the scraping assembly 122 on the surface to be cleaned exceeds the weight of the floor brush device 100 itself, it can also cause the rollers of the floor brush device 100 to lift up, ultimately resulting in severe water residue on the surface to be cleaned. Therefore, when the interference between the lower edge of the scraping component 122 and the surface to be cleaned is 0-5mm, the cleaning effect of the floor brush device 100 and the smoothness of pushing and pulling the floor brush device 100 can be balanced.

[0063] As one possible implementation, the lower edge of the scraping assembly 122 is set in a horizontal or approximately horizontal direction; when the floor brush device 100 moves on the surface to be cleaned, the bending angle of the lower edge of the scraping assembly 122 relative to the vertical direction is equal to or approximately 90°.

[0064] Understandably, the lower edge of the scraping assembly 122 can be set completely horizontally, i.e., the angle between the lower edge of the scraping assembly 122 and the horizontal direction is 0°. Alternatively, the lower edge of the scraping assembly 122 can be set approximately horizontally, making it easier for the lower edge of the scraping assembly 122 to bend when the floor brush device 100 moves. When the interference between the lower edge of the scraping assembly 122 and the surface to be cleaned is sufficiently large, the bending angle of the lower edge of the scraping assembly 122 relative to the vertical direction can be equal to 90°. When the interference between the lower edge of the scraping assembly 122 and the surface to be cleaned decreases, the bending angle of the lower edge of the scraping assembly 122 relative to the vertical direction will decrease, approximately to 90°.

[0065] For example, the angle between the lower edge of the scraping component 122 and the horizontal direction can be 0°, 0.1°, 0.5°, 1°, etc., and this application embodiment does not make specific limitations; the bending angle of the lower edge of the scraping component 122 relative to the vertical direction can be 90°, 89.9°, 89.5°, 89°, etc. When the bending angle of the lower edge of the scraping component 122 relative to the vertical direction is equal to or approximately 90°, the scraping effect can be guaranteed.

[0066] Reference Figure 2 and Figure 3The direction of movement of the floor brush device 100 during cleaning is defined as the X direction, and the width direction of the device body 110 is defined as the Y direction, which is perpendicular to the X direction.

[0067] As one possible implementation, the length direction of the scraping component 122 is parallel to the width direction of the device body 110, and both the length direction of the scraping component 122 and the width direction of the device body 110 are in the Y direction, with the length dimension of the scraping component 122 matching the width dimension of the device body 110. It can be understood that when the device body 110 moves, the width of the moving path is consistent with the width of the device body 110. Because the length dimension of the scraping component 122 is consistent with the width dimension of the device body 110, the scraping range of the scraping component 122 can cover the moving path, avoiding any areas missed during cleaning and improving cleaning efficiency.

[0068] As one possible implementation, the uneven surface 1221 has a plurality of protrusions 1221a and a plurality of recesses 1221b, which are arranged alternately along the length of the scraping assembly 122; when the uneven surface 1221 contacts the surface to be cleaned, the protrusions 1221a abut against the surface to be cleaned, and a water passage is formed between the recesses 1221b and the surface to be cleaned.

[0069] It is understood that when the concave and convex surfaces 1221 contact the surface to be cleaned, the multiple recesses 1221b can form multiple water passages with the surface to be cleaned. The cross-sectional shape of the protrusions 1221a can be any of a triangle, trapezoid, or arc, and this embodiment does not specifically limit this. The end of the protrusion 1221a that contacts the surface to be cleaned can be narrower, thus the gap between the top ends of adjacent protrusions 1221a can be narrower than the gap between their bottom ends, thereby improving the water passage efficiency of the water passages.

[0070] As one possible implementation, the scraping assembly 122 has a flat surface 1222 along the moving direction of the floor brush device 100, and the concave and convex surfaces 1221 are located on the side of the scraping assembly 122 away from the suction port 121, while the flat surface 1222 is located on the side of the scraping assembly 122 facing the suction port 121.

[0071] Understandably, when the uneven surface 1221 comes into contact with the surface to be cleaned, water stains on the surface to be cleaned can pass through the water passage to the other side of the scraping assembly 122, that is, one side of the flat surface 1222, and then be sucked in by the suction port 121; when the flat surface 1222 comes into contact with the surface to be cleaned, along the moving direction of the floor brush device 100, water stains on the surface to be cleaned continuously accumulate on the front side of the flat surface 1222, and then are sucked in by the suction port 121.

[0072] As one possible implementation, the scraping assembly 122 includes a mounting body 1223 and a flexible scraping member 1224. The mounting body 1223 is connected to the device body 110. The upper part of the flexible scraping member 1224 is connected to the mounting body 1223. The lower part of the flexible scraping assembly 122 extends downward toward the device body 110. The concave-convex surface 1221 is provided near the lower part of the flexible scraping member 1224.

[0073] It is understood that the length direction of the protrusion 1221a and the recess 1221b of the uneven surface 1221 can be vertical. The protrusion 1221a and the recess 1221b are arranged near the lower part of the flexible scraper 1224. The length of the protrusion 1221a and the recess 1221b of the uneven surface 1221 is less than or equal to the height of the flexible scraper 1224.

[0074] As one possible implementation, the scraping assembly 122 includes a first scraping assembly 122a and a second scraping assembly 122b. Along the cleaning direction of the floor brush device 100, i.e., along the X direction, the first scraping assembly 122a is located in front of the suction port 121, and the second scraping assembly 122b is located behind the suction port 121. When the floor brush device 100 moves on the surface to be cleaned, the bending directions of the first scraping assembly 122a and the second scraping assembly 122b are the same.

[0075] As one possible implementation, along the cleaning direction of the floor brush device 100, the concave-convex surface 1221 of the first scraping component 122a is located on the front side of the first scraping component 122a, and the flat surface 1222 of the first scraping component 122a is located on the rear side of the first scraping component 122a; the concave-convex surface 1221 of the second scraping component 122b is located on the rear side of the second scraping component 122b, and the flat surface 1222 of the second scraping component 122b is located on the front side of the second scraping component 122b.

[0076] Understandably, along the cleaning direction of the floor brush device 100, the first scraping assembly 122a is located in front of the suction port 121, and the second scraping assembly 122b is located behind the suction port 121. When the floor brush device 100 moves forward, the flexible scraping parts 1224 of the first scraping assembly 122a and the second scraping assembly 122b simultaneously bend backward. The concave and convex surfaces 1221 of the first scraping assembly 122a contact the surface to be cleaned, and the second scraping assembly 122b... The flat surface 1222 of the second scraper assembly 122a contacts the surface to be cleaned. The water stains on the surface to be cleaned first pass through the concave and convex surfaces 1221 of the first scraper assembly 122a and the water passage of the surface to be cleaned, reaching the bottom of the suction port 121. Some of the water stains enter the suction port 121 under the suction force of the suction port 121. The remaining water stains will gather on the front side of the second scraper assembly 122b under the obstruction of the flat surface 1222 of the second scraper assembly 122b and be sucked in by the suction port 121.

[0077] Similarly, along the cleaning direction of the floor brush device 100, when the floor brush device 100 is pulled back, the flexible scraping parts 1224 of the first scraping assembly 122a and the second scraping assembly 122b simultaneously bend forward. The concave-convex surface 1221 of the second scraping assembly 122b contacts the surface to be cleaned, and the flat surface 1222 of the first scraping assembly 122a contacts the surface to be cleaned. The water stains on the surface to be cleaned first reach the suction port 1 through the water passage between the concave-convex surface 1221 of the second scraping assembly 122b and the surface to be cleaned. Below 21, some water stains enter the suction port 121 under the suction force of the suction port 121. The remaining water stains, blocked by the flat surface 1222 of the first scraping component 122a, will gather on the front side of the second scraping component 122b and be sucked in by the suction port 121. In this way, no matter whether the floor brush device 100 moves forward or backward, the flat surface 1222 of the one of the two scraping components 122 that is further back in the direction of movement can contact the surface to be cleaned and work with the suction port 121 to remove water stains and complete the cleaning.

[0078] In some embodiments, the cleaning component 120 further includes a water spraying component 123 disposed between the first scraping component 122a and the second scraping component 122b, and the water spraying component 123 is configured to spray cleaning water onto the surface to be cleaned.

[0079] Understandably, relying solely on the cooperation of the scraping component 122 and the suction port 121, the cleaning effect is limited, and stubborn stains are easily left on the surface to be cleaned. By spraying cleaning water onto the surface to be cleaned through the water spraying component 123, the surface to be cleaned can be rinsed and moistened. Then, the scraping component 122 scrapes the surface, and the wastewater after scraping is finally sucked in by the suction port 121, so that the floor brush device 100 can still have a good cleaning effect without the roller brush.

[0080] It should be noted that the water spray assembly 123 is located between the first scraping assembly 122a and the second scraping assembly 122b. The first scraping assembly 122a and the second scraping assembly 122b can form a closed cleaning cavity with the two side walls in the width direction of the device body 110, so that the cleaning water sprayed by the water spray assembly 123 will not splash into the surrounding environment. The water spray assembly 123 is provided with a plurality of water spray holes 1231, which are arranged at intervals along the width direction of the device body 110, and can spray cleaning water onto the surface to be cleaned.

[0081] For example, the water spray assembly 123 has two water spray holes 1231, which are located at both ends of the water spray assembly 123 along the width direction of the device body 110. The suction port 121 is located in the middle of the width direction of the device body 110. When the water spray assembly 123 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 suction port 121 in the middle. During the process of the water flow moving towards the suction port 121 on the surface to be cleaned, the surface to be cleaned can be wetted.

[0082] In some embodiments, the suction port 121 may include a first suction port 121a, a second suction port 121b, and a third suction port 121c. Along the cleaning direction of the floor brush device 100, the first suction port 121a is located in front of the first scraping assembly 122a, the second suction port 121b is located between the first scraping assembly 122a and the water spray assembly 123, and the third suction port 121c is located between the water spray assembly 123 and the second scraping assembly 122b. When the water spray assembly 123 sprays water, the second suction port 121b and the third suction port 121c can recover the cleaning water sprayed by the water spray assembly 123. Along the cleaning direction of the floor brush device 100, when the floor brush device 100 moves forward, the second suction port 121b can suck in some sewage, and the sewage accumulated in front of the second scraping assembly 122b is sucked in by the third suction port 121c; when the floor brush device 100 is pulled back, the third suction port 121c can suck in some sewage, and the sewage accumulated in front of the first scraping assembly 122a is sucked in by the second suction port 121b.

[0083] It should be noted that the first suction port 121a and the second suction port 121b are separated by the first scraping assembly 122a. The diameter of the first suction port 121a can be larger than the diameter of the second suction port 121b, so that when the floor brush device 100 moves forward in the cleaning direction, the first suction port 121a can suck in large particles of debris. The top of the first scraping assembly 122a is provided with a ventilation notch 1225, which connects the first suction port 121a and the second suction port 121b. This allows some debris to be sucked in by the second suction port 121b through the ventilation notch 1225, improving cleaning efficiency.

[0084] This application also provides a cleaning device 10, which includes a main body 200 and the aforementioned floor brush device 100. The top of the main body 200 may be equipped with a handle for easy gripping by cleaning personnel. The main body 200 of the cleaning device 10 is equipped with a cleaning water tank and a water pump. The water pump is connected to the cleaning water tank and is configured to provide cleaning water to the spray assembly 123. With a fixed cleaning water tank capacity, the water pump can control the water output of the spray assembly 123, ensuring that the spray assembly 123 can continuously spray cleaning water during the cleaning process. The main body 200 may also be equipped with a wastewater tank, which is connected to the floor brush duct 111. After the suction port 121 sucks in the cleaning wastewater, the wastewater can be carried by the airflow conveyor belt through the floor brush duct 111 into the wastewater tank for recycling.

[0085] This application provides a floor brush device 100 and a cleaning device 10. The floor brush device 100 includes a device body 110 and a cleaning component 120. The device body 110 has a floor brush air duct 111 with an air inlet 1111. The cleaning component 120 is disposed at the air inlet 1111 and connected to the device body 110. The cleaning component 120 has a suction port 121 facing downwards from the device body 110 and communicating with the air inlet 1111. The cleaning component 120 includes a scraping component 122, the lower edge of which is lower than the lower edge of the device body 110. When the floor brush device 100 is placed on the surface to be cleaned, the lower edge of the scraping component 122 has an interference of 0-5mm with the surface to be cleaned. The scraping component 122 also has a concave-convex surface 1221. When the floor brush device 100 moves on the surface to be cleaned, the lower edge of the scraping component 122 bends to the side opposite to the direction of movement so that the concave-convex surface 1221 contacts the surface to be cleaned and forms a water passage. The water passage allows water stains to pass through the scraping component 122 and enter below the suction port 121, where they are sucked in, preventing water stains from remaining on the surface to be cleaned and resulting in a better cleaning effect.

[0086] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
