Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and in particular 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 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 usually uses roller brushes to clean the floor. However, after cleaning, the roller brushes that absorb wastewater will leave wastewater residue, which can easily cause the roller brushes to produce odors. Therefore, there are currently cleaning equipment without roller brushes that suck up wastewater from the floor through a suction port.

[0004] However, the cleaning effect of current brushless cleaning equipment is relatively poor. 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, which includes a device body, a water spraying component, a first scraping component, and a second scraping component; the device body has a floor brush air duct and a suction port, and the suction port is connected to the floor brush air duct.

[0007] Along the cleaning direction of the floor brush device, the first scraper and the second scraper are spaced apart at the bottom of the main body of the device, and a cleaning cavity is formed between the first scraper and the second scraper; the suction port and the water spray assembly are both located between the first scraper and the second scraper, and the water spray assembly is configured to spray water onto the surface to be cleaned in the cleaning cavity.

[0008] This application provides a floor brush device that sets a water spray component and a suction port in a cleaning cavity formed between two scraping components, creating a cleaning area between the first and second scraping components. After the water spray component wets and cleans this area, the suction port draws wastewater into the floor brush duct through negative pressure, achieving a fine cleaning function without the need for a roller brush and providing excellent cleaning results.

[0009] As an optional implementation, the first end of the first scraper is connected to the device body, and the second end of the first scraper extends downward toward the device body; the first end of the second scraper is connected to the device body, and the second end of the second scraper extends downward toward the device body.

[0010] When the floor brush device cleans the surface to be cleaned, the second end of the first scraper and the second end of the second scraper are both in contact with the surface to be cleaned, and a cleaning cavity is formed between the first scraper and the second scraper.

[0011] With this configuration, the suction from the first and second suction ports makes it easier for the cleaning chamber to generate a larger negative pressure, efficiently drawing the wastewater between the first and second scraper components into the floor brush duct and improving cleaning efficiency.

[0012] As an optional implementation, the suction port includes a first suction port and a second suction port; the first suction port and the second suction port are spaced apart at the bottom of the device body along the cleaning direction of the floor brush device; the water spray assembly is disposed between the first suction port and the second suction port.

[0013] With this configuration, there are suction ports between the water spray assembly and the front and rear scrapers for drawing in wastewater, thus avoiding water stains remaining between the water spray assembly and the scrapers.

[0014] As an optional implementation, the first scraper is disposed along the edge of the first suction port, and the length of the first scraper matches the length of the first suction port; the second scraper is disposed along the edge of the second suction port, and the length of the second scraper matches the length of the second suction port.

[0015] This configuration ensures that the cleaning range of the first and second scraping components covers all positions along the length of the first and second suction ports, preventing water stains from remaining.

[0016] As an optional implementation, the first suction port and the second suction port are arranged in parallel and both extend along the width direction of the main body of the device.

[0017] With this configuration, the first and second suction ports can form two strip-shaped suction areas, which have stronger negative pressure suction. This allows the water sprayed by the water spray component to flow along the surface to be cleaned under the action of suction, resulting in a better cleaning effect.

[0018] As an optional implementation, the main body of the device includes a suction port bracket, the suction port bracket having a suction chamber, the air inlet of the suction chamber facing downwards from the main body of the device, and the air outlet of the suction chamber communicating with the floor brush duct.

[0019] The water spray assembly is located at the air inlet of the suction chamber, and divides the air inlet of the suction chamber into the first suction port and the second suction port.

[0020] This design allows the water spray component to quickly and thoroughly wet the area below the first and second suction ports, while also ensuring that the first and second suction ports are as close as possible to each other, thereby generating greater negative pressure suction.

[0021] As an optional implementation, the main body of the device includes a suction port bracket, which has two suction chambers; the air inlets of the two suction chambers face downwards from the main body of the device and respectively form the first suction port and the second suction port; the air outlets of the two suction chambers are connected to the floor brush duct; and the water spray assembly is located between the two suction chambers.

[0022] With this configuration, the first and second suction ports can draw sewage into the floor brush duct through different channels, thereby improving sewage suction efficiency.

[0023] As an optional implementation, at least one of the first scraper and the second scraper has a sealing surface and a water-passing surface, the sealing surface being disposed towards the water spray assembly, and the water-passing surface being disposed away from the water spray assembly.

[0024] When the water-passing surface comes into contact with the surface to be cleaned, a water-passing channel is formed between the sealing surface and the surface to be cleaned.

[0025] This design allows for two main advantages. First, the sealing surface can contact the surface to be cleaned to scrape water, causing wastewater to collect on the side facing the suction port and be sucked in, thus improving cleaning efficiency. Second, the water-passing surface can contact the surface to be cleaned, allowing water stains to pass through the scraper and enter below the suction port, where they are sucked in, preventing water stains from remaining on the surface and resulting in a better cleaning effect.

[0026] As an optional implementation, both the first scraper and the second scraper have the sealing surface and the water-passing surface.

[0027] Along the cleaning direction of the floor brush device, the first suction port is located in front of the second suction port, the sealing surface of the first scraper faces the rear of the floor brush device, and the water-passing surface of the first scraper faces the front of the floor brush device; the sealing surface of the second scraper faces the front of the floor brush device, and the water-passing surface of the second scraper faces the rear of the floor brush device.

[0028] With this configuration, when the floor brush device moves back and forth to clean, the wastewater in front of it in the direction of movement can pass through the scraper and be sucked into the suction port.

[0029] As an optional implementation, the side of the first scraper facing the first suction port and the side away from the first suction port are both sealing surfaces; the side of the second scraper facing the second suction port and the side away from the second suction port are both sealing surfaces.

[0030] This design improves the sealing effect of the cleaning chamber between the first and second scraping components, ensuring that wastewater is collected in the area below the first and second suction ports, thus preventing water residue.

[0031] As an optional implementation, the floor brush device has a third suction port; the third suction port is located in front of the first suction port and the second suction port along the cleaning direction of the floor brush device; the third suction port is connected to the floor brush air duct.

[0032] This setup allows for the intake of dust, particulate matter, and some wastewater through the third suction port before the water spray unit wets and cleans the floor, achieving a coarse suction followed by a fine wash.

[0033] As an optional implementation, a flexible element is provided on the rear side of the third suction port along the cleaning direction, and the lower edge of the flexible element has a gap with the surface to be cleaned.

[0034] This design can block large pieces of trash and debris, preventing blockage of the suction port at the back.

[0035] Secondly, this application provides a cleaning device, which includes a device body and a floor brush device as described in the above technical solution, wherein the floor brush device is movably connected to the device body.

[0036] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a water spray assembly, a first scraper, and a second scraper. The main body has a floor brush air duct and a suction port, with the suction port connected to the air duct. Along the cleaning direction of the floor brush device, the first and second scrapers are spaced apart at the bottom of the main body, forming a cleaning chamber between them. The suction port and the water spray assembly are both located between the first and second scrapers. The water spray assembly is configured to spray water onto the surface to be cleaned within the cleaning chamber, eliminating the need for a roller brush and achieving a thorough cleaning function with excellent cleaning results.

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] Cleaning equipment with vacuuming and mopping functions typically uses a floor brush to clean floors. The floor brush is equipped with a roller brush and a water tank. The water tank supplies water to wet the roller brush, which then rolls on the floor to achieve a wet mopping effect. The floor brush usually also has a suction port to suck up debris and wastewater scraped off the roller brush.

[0054] However, in current cleaning equipment, the roller brush on the floor brush is usually wrapped with a cleaning component that easily absorbs water. During the cleaning process, the cleaning component is squeezed by the scraper to remove the absorbed sewage. After cleaning, water stains are easily left on the cleaned floor, resulting in poor cleaning effect.

[0055] In addition, the water on the roller brush cannot be completely scraped off. After cleaning, water stains will remain on the roller brush. If the cleaning parts on the roller brush are not removed and dried in time, the roller brush is prone to odor or even mold.

[0056] Current brushless cleaning equipment is unable to clean stubborn stains on the floor, leaving stains after cleaning and resulting in poor cleaning performance.

[0057] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. The brush eliminates the roller brush structure on the floor brush and instead features two suction ports with a water spray component positioned between them to wet the corresponding floor surface. Furthermore, scrapers are installed on the outer sides of each suction port, creating a space for fine cleaning. This allows wastewater to be efficiently drawn in through the two suction ports, preventing stains from remaining without the roller brush. Additionally, the cleaning water entering the suction ports from the surface to be cleaned removes dust and stains, improving cleaning efficiency.

[0058] In addition, since the roller brush on the floor brush device can be eliminated, the floor can be cleaned by the water spraying component, and the wastewater can be sucked up by the suction port. In this way, there is no need to dry it after cleaning and no odor will be produced.

[0059] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0060] 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.

[0061] 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 structure of the floor brush device provided in the embodiments of this application; Figure 3 This is a partial view of the suction port in the floor brush device provided in an embodiment of this application.

[0062] See Figures 1 to 3 As shown, this application provides a floor brush device 100 for use in a cleaning device 10. The floor brush device 100 can move on the surface to be cleaned and clean the surface. The floor brush device 100 includes a device body 110 and a water spray assembly 120. The water spray assembly 120 is disposed on the device body 110 and configured to spray water onto the surface to be cleaned below the device body 110, thereby wetting the surface to be cleaned.

[0063] The main body 110 of the device has a floor brush duct 111 and a suction port, which is connected to the floor brush duct 111. During the cleaning process of the floor brush device 100, the suction port faces the surface to be cleaned, and the cleaning water sprayed by the water spray component 120 can be sucked into the floor brush duct 111 through the suction port.

[0064] Along the cleaning direction of the floor brush device 100, the first scraper 130a and the second scraper 130b are spaced apart at the bottom of the device body 110, and a cleaning cavity 101 is formed between the first scraper 130a and the second scraper 130b; the suction port and the water spray assembly 120 are both located between the first scraper 130a and the second scraper 130b, and the water spray assembly 120 is configured to spray water onto the surface to be cleaned in the cleaning cavity 101.

[0065] In some embodiments, the suction port includes a first suction port 112 and a second suction port 113. The first suction port 112 and the second suction port 113 are spaced apart at the bottom of the device body 110 along the cleaning direction of the floor brush device 100. A water spray assembly 120 is disposed between the first suction port 112 and the second suction port 113.

[0066] Understandably, the first suction port 112 and the second suction port 113 are spaced apart at the bottom of the main body 110 of the device along the cleaning direction of the floor brush device 100. The first suction port 112 and the second suction port 113 face downwards from the main body 110 of the device. The water spray assembly 120 is disposed between the first suction port 112 and the second suction port 113. The negative pressure suction generated by the first suction port 112 and the second suction port 113 allows the cleaning water sprayed by the water spray assembly 120 to flow along the surface to be cleaned after rinsing it, and simultaneously be drawn into the floor brush air duct 111 through the first suction port 112 and the second suction port 113. In this process, dust and stubborn stains on the surface to be cleaned can be removed, achieving a good cleaning effect.

[0067] In some embodiments, the floor brush device 100 includes a first scraper 130a and a second scraper 130b. The first scraper 130a is located on the side of the first suction port 112 opposite to the second suction port 113, and the second scraper 130b is located on the side of the second suction port 113 opposite to the first suction port 112.

[0068] During the cleaning process of the floor brush device 100, the first scraper 130a and the second scraper 130b simultaneously come into contact with the surface to be cleaned, thereby forming a fine cleaning area between the first scraper 130a and the second scraper 130b. The first suction port 112 and the second suction port 113 are both located within this cleaning area. The water sprayed by the water spray assembly 120 wets the surface to be cleaned within this cleaning area, and the negative pressure suction generated by the first suction port 112 and the second suction port 113 draws the wastewater into the floor brush air duct 111.

[0069] It is understandable that by utilizing the cleaning area formed between the first scraper 130a and the second scraper 130b, and cooperating with the first suction port 112 and the second suction port 113 to generate negative pressure suction, a large negative pressure can be generated in the cleaning area. In this way, after the water spray assembly 120 sprays water to wet the surface to be cleaned, the water is drawn into the first suction port 112 and the second suction port as it flows across the surface to be cleaned. As the cleaning water passes through the cleaning area between the first scraper 130a and the second scraper 130b, it will carry away dust and stains, thus achieving a good cleaning effect.

[0070] It should be noted that in the floor brush device 100 provided in this application embodiment, the water spraying component 120 is disposed between the first suction port 112 and the second suction port 113, and the cleaning area formed between the first scraper 130a and the second scraper 130b is relatively sealed, so that after the water spraying component 120 wets the area, the first suction port 112 and the second suction port 113 simultaneously suck the sewage into the floor brush air duct 111 through negative pressure, which has a good cleaning effect while avoiding water stains.

[0071] Furthermore, compared to existing technologies, the floor brush device 100 in this embodiment eliminates the need for a roller brush. Wastewater can be directly sucked in through the first suction port 112 and the second suction port 113, and the first scraper 130a and the second scraper 130b can scrape the surface to be cleaned, thus preventing water stains from remaining. Wastewater will also not remain on the floor brush device 100, preventing odors from developing when the device is left idle after cleaning.

[0072] Please continue to refer to Figures 1 to 3 In some embodiments, the first end of the first scraper 130a is connected to the device body 110, and the second end of the first scraper 130a extends downward toward the device body 110; the first end of the second scraper 130b is connected to the device body 110, and the second end of the second scraper 130b extends downward toward the device body 110.

[0073] Understandably, when the floor brush device 100 cleans the surface to be cleaned, the second ends of both the first scraper 130a and the second scraper 130b are in contact with the surface, and there is a certain amount of interference between them, forming a cleaning chamber 101 between the first scraper 130a and the second scraper 130b. Under the suction of the first suction port 112 and the second suction port 113, the cleaning chamber 101 more easily forms a larger negative pressure, efficiently drawing the wastewater between the first scraper 130a and the second scraper 130b into the floor brush air duct 111, thereby improving cleaning efficiency.

[0074] The direction of movement of the floor brush device 100 during cleaning is defined as the X direction, and the width direction of the floor brush device 100 is defined as the Y direction, which is perpendicular to the x-axis. Figure 2The Y direction is perpendicular to the X direction. Both the first suction port 112 and the second suction port 113 can be set along the Y direction, and both the first suction port 112 and the second suction port 113 can be elongated.

[0075] In this embodiment, the first scraping member 130a can extend along the width direction of the device body 110. The second scraping member 130b can extend along the width direction of the device body 110.

[0076] The specific locations of the first scraper 130a and the second scraper 130b, as well as the specific location of the water spray assembly 120, will be described in detail below.

[0077] Please continue to refer to Figures 1 to 3 In one possible implementation, a first scraper 130a is disposed along the edge of a first suction port 112, and the length of the first scraper 130a matches the length of the first suction port 112. A second scraper 130b is disposed along the edge of a second suction port 113, and the length of the second scraper 130b matches the length of the second suction port 113.

[0078] It is understandable that when the first suction port 112 and the second suction port 113 suck up sewage, they have a cleaning coverage area as large as possible in the width direction of the main body 110 of the device, which can ensure that the cleaning range of the first scraper 130a and the second scraper 130b covers all positions in the length direction of the first suction port 112 and the second suction port 113, thus avoiding water stains.

[0079] For example, the first suction port 112 and the second suction port 113 are arranged in parallel and both extend along the width direction of the device body 110. The first suction port 112 and the second suction port 113 can form two strip-shaped suction areas with stronger negative pressure suction, so that the water sprayed by the water spray assembly 120 flows along the surface to be cleaned under the action of suction, resulting in a better cleaning effect.

[0080] It should be noted that when the floor brush device 100 moves on the surface to be cleaned, there is a gap between the bottom of the device body 110 and the surface to be cleaned, and the first scraping member 130a and the second scraping member 130b protrude downwards from the bottom of the device body 110 to contact the surface to be cleaned and generate elastic deformation.

[0081] In some embodiments, the device body 110 includes a suction port bracket 140, the suction port bracket 140 having a suction chamber 141, the air inlet of the suction chamber 141 facing downwards from the device body 110, and the air outlet of the suction chamber 141 communicating with the floor brush duct 111.

[0082] The water spray assembly 120 is located at the air inlet of the suction chamber 141 and divides the air inlet of the suction chamber 141 into a first suction port 112 and a second suction port 113. Thus, the water spray assembly 120 can not only spray water but also serve as a structural component to divide the air inlet of the suction chamber 141 into sections.

[0083] Understandably, by using the water spray assembly 120 to divide the air inlet of the suction chamber 141 into sections, on the one hand, the water spray assembly 120 can quickly and thoroughly wet the area below the first suction port 112 and the second suction port 113, resulting in a better cleaning effect; on the other hand, by bringing the first suction port 112 and the second suction port 113 as close as possible to cooperate with each other, the cleaning chamber 101 between the first scraper 130a and the second scraper 130b can generate a greater negative pressure suction, avoiding water stains.

[0084] In other embodiments, the main body 110 includes a suction port bracket 140, which has two suction chambers 141. The air inlets of the two suction chambers 141 face downwards from the main body 110 and form a first suction port 112 and a second suction port 113, respectively; the air outlets of the two suction chambers 141 are connected to the floor brush duct 111. A water spray assembly 120 may be disposed between the two suction chambers 141.

[0085] It is understandable that the first suction port 112 and the second suction port 113 can respectively draw sewage into the floor brush duct 111 through different channels, thereby improving the sewage suction efficiency.

[0086] The structure of the first scraping component 130a and the second scraping component 130b will be described in detail below.

[0087] Figure 4 A schematic diagram of the structure of the first scraping component in the floor brush device provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the second type of scraping component in the floor brush device provided in the embodiments of this application.

[0088] Please refer to Figure 4 and Figure 5 and combined Figures 1 to 3 In one possible implementation, at least one of the first scraper 130a and the second scraper 130b has a sealing surface 131 and a water-passing surface 132, with the sealing surface 131 facing the water spray assembly 120 and the water-passing surface 132 facing away from the water spray assembly 120.

[0089] When the water-passing surface 132 contacts the surface to be cleaned, a water-passing channel 1321 is formed between the sealing surface 131 and the surface to be cleaned. When the sealing surface 131 contacts the surface to be cleaned, a good seal can be ensured, achieving a water-scraping effect.

[0090] Understandably, the first scraper 130a is designed with different structures on two sides. On one hand, it can scrape water by contacting the surface to be cleaned through the sealing surface 131, so that the wastewater collects on the side facing the suction port and is sucked in by the suction port, improving cleaning efficiency. On the other hand, it can also contact the surface to be cleaned through the water-passing surface 132, so that water stains can pass through the scraper and enter the area below the suction port and be sucked in by the suction port, avoiding water stains remaining on the surface to be cleaned and achieving a better cleaning effect.

[0091] In some embodiments, both the first scraper 130a and the second scraper 130b have a sealing surface 131 and a water-passing surface 132.

[0092] Along the cleaning direction of the floor brush device 100, the first suction port 112 is located in front of the second suction port 113. The sealing surface 131 of the first scraper 130a faces the rear of the floor brush device 100, and the water-passing surface 132 of the first scraper 130a faces the front of the floor brush device 100. The sealing surface 131 of the second scraper 130b faces the front of the floor brush device 100, and the water-passing surface 132 of the second scraper 130b faces the rear of the floor brush device 100. When the floor brush device 100 reciprocates for cleaning, the wastewater in front of it along its direction of movement can pass through the scrapers and be sucked into the suction port.

[0093] Understandably, when the brush device 100 moves forward in the X direction, both the first scraper 130a and the second scraper 130b bend towards the rear of the device body 110 in the cleaning direction. At this time, the water-passing surface 132 of the first scraper 130a contacts the surface to be cleaned, allowing the wastewater from the surface to be cleaned in the cleaning direction to pass through the first scraper 130a and enter below the first suction port 112, where it is sucked into the first suction port 112. Meanwhile, the sealing surface 131 of the second scraper 130b contacts the surface to be cleaned, acting as a scraper to prevent water stains from remaining.

[0094] When the ground brush device 100 moves backward in the X direction, both the first scraper 130a and the second scraper 130b bend forward relative to the device body 110 in the cleaning direction. At this time, the sealing surface 131 of the first scraper 130a on the front side contacts the surface to be cleaned, while the water-passing surface 132 of the second scraper 130b on the rear side contacts the surface to be cleaned, playing a corresponding role, which will not be described in detail here.

[0095] Take the first scraping component 130a and the first suction port 112 as an example.

[0096] Understandably, when the first scraper 130a bends towards the first suction port 112, the water-passing surface 132 contacts the surface to be cleaned. As the floor brush device 100 moves, wastewater can pass through the water-passing channel 1321 and enter below the first suction port 112 via the first scraper 130a. When the first scraper 130a bends away from the first suction port 112, the sealing surface 131 contacts the surface to be cleaned. As the floor brush device 100 moves, the first scraper 130a can scrape off and collect water stains on the surface to be cleaned, preventing water stains from remaining.

[0097] For example, the water-passing surface 132 has an uneven structure. Along the length direction of the first scraper 130a, the uneven structure is arranged from one end of the first scraper 130a to the other end. When the water-passing surface 132 contacts the surface to be cleaned, a plurality of water-passing channels 1321 are formed between the uneven structure and the surface to be cleaned.

[0098] For example, the concave-convex structure includes a plurality of protrusions 1322, which are spaced apart along the length of the first scraper 130a. When the water-passing surface 132 contacts the surface to be cleaned, the protrusions 1322 abut against the surface to be cleaned, and a water-passing channel 1321 is formed between the area between adjacent protrusions 1322 and the surface to be cleaned.

[0099] For example, the sealing surface 131 is a plane, which can ensure good sealing when the sealing surface 131 contacts the surface to be cleaned.

[0100] It should be noted that in the floor brush device 100 provided in this application embodiment, the first suction port 112 can be elongated, giving it a strong negative pressure suction to draw in wastewater, achieving a good cleaning effect and preventing water stains from remaining. During the cleaning process, the water passage 1321 allows wastewater to pass through under the action of negative pressure suction, while preventing large particles and debris from passing through the first scraper 130a and clogging the first suction port 112, thereby ensuring the smoothness of the cleaning process.

[0101] For example, the cross-sectional shape of the protrusion 1322 can be any of a triangle, trapezoid, or arc, and this application embodiment does not specifically limit this. The end of the protrusion 1322 that contacts the surface to be cleaned can be narrower, so that the gap between the top ends of adjacent protrusions 1322 can be narrower than the gap at the bottom ends, thereby improving the water flow efficiency of the water passage 1321.

[0102] In other embodiments, the side of the first scraper 130a facing the first suction port 112 and the side facing away from the first suction port 112 are both sealing surfaces 131. The side of the second scraper 130b facing the second suction port 113 and the side facing away from the second suction port 113 are both sealing surfaces 131.

[0103] Understandably, the sealing surface 131 can improve the sealing effect of the cleaning cavity 101 between the first scraper 130a and the second scraper 130b, so that the sewage is collected in the area below the first suction port 112 and the second suction port 113, avoiding water stains.

[0104] It should be noted that both the first scraping component 130a and the second scraping component 130b can be made of elastic materials such as rubber or silicone. Both the first scraping component 130a and the second scraping component 130b can be strip-shaped structures.

[0105] In this embodiment, the water spray assembly 120 may include a water spray housing and a water spray cover. The water spray housing and the water spray cover are connected and form a water spray channel. The side of the water spray housing facing the lower part of the device body 110 may be provided with water spray holes, which spray water onto the surface to be cleaned, thereby efficiently wetting and cleaning the surface to be cleaned.

[0106] For example, there are multiple water spray holes, which are arranged at intervals along the width direction of the device body 110, thereby ensuring uniform water supply to all positions along the width direction of the device body 110. This application embodiment does not limit the specific size, shape, or number of the water spray holes.

[0107] Please continue to refer to Figures 1 to 3 In one possible implementation, the floor brush device 100 has a third suction port 114. The third suction port 114 is located in front of the first suction port 112 and the second suction port 113 along the cleaning direction of the floor brush device 100. The third suction port 114 is connected to the floor brush air duct 111.

[0108] The width of the third suction port 114 can be greater than the width of the first suction port 112 and the second suction port 113. Before the water spray assembly 120 wets and cleans the floor, dust, particulate matter, and some wastewater are sucked in through the third suction port 114 at the front end of the main body 110 of the device, achieving the effect of coarse suction followed by fine cleaning.

[0109] In addition, when the first scraper 130a adopts a water-permeable structure, large debris can be prevented from clogging the water passage 1321 of the first scraper 130a, thus improving the cleaning effect.

[0110] Understandably, as the floor brush device 100 moves forward, large volumes of garbage and debris can first be sucked into the floor brush air duct 111 through the third suction port 114. Then, by wetting the surface to be cleaned, the wastewater generated from cleaning stubborn dust and stains can be sucked in through the first suction port 112 and the second suction port 113, thereby improving the cleaning effect.

[0111] For example, the floor brush device 100 is provided with an air duct housing, which forms a floor brush air duct 111. The third suction port 114 can be located at the front end of the air duct housing. The first suction port 112 and the second suction port 113 can be connected to the rear end of the air duct housing, so that the airflow and debris sucked in from the third suction port 114, as well as the airflow and sewage sucked in from the first suction port 112 and the second suction port 113, will converge at the rear end of the air duct housing and enter the sludge collection chamber together.

[0112] It should be noted that a flexible element 130c can also be provided on the rear side of the third suction port 114 along the cleaning direction. The flexible element 130c can have a gap with the surface to be cleaned, so that while blocking large debris and garbage, water stains and dust on the ground can be left unblocked. The water spray assembly 120 is used in conjunction with the first suction port 112 and the second suction port 113 for cleaning. In this way, large garbage and small dust particles can be separated and sucked in by different suction ports.

[0113] This application provides a cleaning device 10, which includes a main body 200 and a floor brush device 100 as described above. The floor brush device 100 is movably connected to the main body 200. When performing cleaning operations, the user can move the floor brush device 100 by pushing or pulling the main body 200.

[0114] It is understandable that a suction pipe can be connected between the floor brush device 100 and the main body 200, and a sewage tank can be installed on the main body 200. Sewage sucked in by the floor brush device 100 can enter the sewage tank through the suction pipe.

[0115] In addition, a fan unit can be installed on the main body 200 of the equipment. The fan unit is used to generate negative pressure airflow, which in turn causes the first suction port 112 and the second suction port 113 to generate negative pressure suction. The clean airflow after being filtered by the sewage tank passes through the fan unit and is discharged to the outside of the main body 200 of the equipment.

[0116] This application provides a floor brush device and cleaning equipment. The floor brush device includes a main body, a water spray assembly, a first scraper, and a second scraper. The main body has a floor brush duct, a first suction port, and a second suction port, both of which are connected to the floor brush duct. The first and second suction ports are spaced apart at the bottom of the main body along the cleaning direction of the floor brush device. The water spray assembly is disposed between the first and second suction ports and configured to spray water onto the surface to be cleaned below the main body. The first scraper is located on the side of the first suction port opposite to the second suction port, and the second scraper is located on the side of the second suction port opposite to the first suction port, thereby forming a fine cleaning area between the first and second scrapers. After the water spray assembly wets this area, the first and second suction ports simultaneously draw wastewater into the floor brush duct through negative pressure, achieving a good cleaning effect while avoiding water stains.

[0117] 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.
