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 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 uses a floor brush to clean the floor. The floor brush adopts a front suction and rear mopping structure. The suction port on the front side can suck up garbage and debris on the floor, and the roller brush on the rear side rolls on the floor to achieve the effect of wet mopping.

[0004] However, currently, after cleaning equipment finishes cleaning, there is often sewage residue on the roller brush of the floor brush, which makes the floor brush prone to producing odors. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that after cleaning is completed, there is sewage residue on the roller brush of the floor brush, which makes the floor brush prone to producing odor.

[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, a first suction port, and a second suction port, both of which are connected to the floor brush air duct.

[0007] Along the cleaning direction of the floor brush device, the first suction port is located in front of the second suction port; the first scraper is located on the edge of the first suction port facing the second suction port; the second scraper is located on the side of the second suction port away from the first suction port; the water spraying assembly is disposed between the first suction port and the second suction port, and is disposed close to the second suction port, and the water spraying assembly is configured to spray water onto the surface to be cleaned below the main body of the device.

[0008] The floor brush device provided in this application has a first suction port and a second suction port arranged in front and behind. The first suction port sucks up garbage and debris to achieve a coarse suction function, and the second suction port sucks up the wastewater after the water spray component wets the ground to achieve a fine cleaning function. This achieves the effect of coarse suction followed by fine cleaning. With the first and second scraping parts, water stains can be avoided on the ground, thus eliminating the need for a roller brush structure. After cleaning, there is no need to dry the floor and no odor is produced.

[0009] As an optional implementation, the water spray assembly extends along the length of the second suction port.

[0010] This setup allows for simultaneous wetting of the area corresponding to the length of the second suction port, increasing the cleaning area.

[0011] As an optional implementation, the flow cross-sectional dimension of the first suction port is larger than that of the second suction port.

[0012] This design ensures that the first suction port can suck up garbage and debris, while the second suction port can generate a high negative pressure suction, thus improving the efficiency of sewage suction.

[0013] As an optional implementation, in the vertical direction, the lower edge of the first scraper is higher than the lower edge of the second scraper.

[0014] When the floor brush device cleans the surface to be cleaned, the lower edge of the first scraper has a gap with the surface to be cleaned, and the lower edge of the second scraper abuts against and bends against the surface to be cleaned.

[0015] With this design, after the first suction port sucks in the debris, the remaining water can pass through the first scraper and be sucked in by the second suction port, improving cleaning efficiency while preventing the second suction port from getting clogged.

[0016] As an optional implementation, the main body of the device has a third suction port, which is connected to the floor brush duct; the third suction port is located on the side of the water spray assembly away from the second suction port.

[0017] With this configuration, when the water spray component sprays out cleaning water to wet the ground, wastewater can be simultaneously drawn in through the second and third suction ports on both sides, avoiding wastewater residue.

[0018] As an optional implementation, the floor brush device further includes a third scraper located on the side edge of the third suction port opposite to the second suction port.

[0019] With this configuration, a narrower cleaning chamber can be formed between the second and third scraping components, thereby creating a larger negative pressure suction force and improving the efficiency of sewage suction.

[0020] As an optional implementation, at least one of the second and third scraping members has a sealing surface and a water-passing surface, the sealing surface being disposed facing the water spray assembly, and the water-passing surface being disposed away from the water spray assembly.

[0021] When the water-passing surface comes into contact with the surface to be cleaned, a water-passing channel is formed between the water-passing surface and the surface to be cleaned; when the sealing surface comes into contact with the surface to be cleaned, the sealing surface and the surface to be cleaned are relatively sealed.

[0022] 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.

[0023] As an optional implementation, both the second scraper and the third scraper have the sealing surface and the water-passing surface; the sealing surface of the second scraper faces the front side of the floor brush device, and the water-passing surface of the second scraper faces the rear side of the floor brush device; the sealing surface of the third scraper faces the rear side of the floor brush device, and the water-passing surface of the third scraper faces the front side of the floor brush device.

[0024] 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 second and third suction ports.

[0025] As an optional implementation, the side of the second scraper facing the second suction port and the side away from the second suction port are both sealing surfaces; the side of the third scraper facing the third suction port and the side away from the third suction port are both sealing surfaces.

[0026] This design improves the sealing effect of the cleaning chamber between the second and third scraping components, ensuring that wastewater is collected in the area below the second and third suction ports, thus preventing water stains from remaining.

[0027] As an optional implementation, the floor brush duct has an air inlet end, and the first scraper, the second suction port and the third suction port are all located at the air inlet end of the floor brush duct.

[0028] Wherein, the first suction port is formed between the front side of the first scraper along the cleaning direction of the floor brush device and the front side of the air inlet; the second suction port is formed between the second scraper and the water spray assembly; and the third suction port is formed between the water spray assembly and the first scraper.

[0029] This setup allows the suction nozzles for coarse cleaning and fine cleaning to be positioned as close as possible to avoid water residue.

[0030] 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.

[0031] 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, a first suction port, and a second suction port, both of which are connected to the floor brush air duct. Along the cleaning direction of the floor brush device, the first suction port is located in front of the second suction port; the first scraper is located on the edge of the first suction port facing the second suction port; the second scraper is located on the side of the second suction port away from the first suction port; the water spray assembly is disposed between the first and second suction ports, and is positioned close to the second suction port. The water spray assembly is configured to spray water onto the surface to be cleaned below the main body of the device, achieving a coarse suction followed by a fine cleaning effect. Combined with the first and second scrapers, water stains can be avoided on the floor, thus eliminating the need for a roller brush structure. After cleaning, drying is not required, and no odor is generated.

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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Currently, in 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. However, the water cannot be completely removed. After cleaning is completed, water stains will remain on the roller brush. If the cleaning component on the roller brush is not removed and dried in time, the floor 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. By setting two suction ports distributed front and back for coarse suction and fine cleaning respectively, during the cleaning process, the coarse suction port sucks up all the debris and waste, and the water spray component can wet the cleaned floor. The fine cleaning suction port sucks the wastewater generated during cleaning into the device. As the cleaning water enters the fine cleaning suction port from the surface to be cleaned, it can remove dust and stains, improving cleaning efficiency. Thus, the roller brush structure on the floor brush can be eliminated, and there is no need to dry it after cleaning, and no odor is generated.

[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.

[0054] 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 3This is a partial view of the suction port in the floor brush device provided in an embodiment of this application.

[0055] 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.

[0056] The main body 110 of the device includes a floor brush duct 111, a first suction port 112, and a second suction port 113, both of which are connected to the floor brush duct 111. During the cleaning process of the floor brush device 100, both the first suction port 112 and the second suction port 113 face the surface to be cleaned. 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, with the two arranged one in front of the other. As the floor brush device 100 moves forward, the first suction port 112 at the front can suck in debris and impurities, while the second suction port 113 at the rear can suck in wastewater and water stains generated during cleaning.

[0057] It is understood that the water spray assembly 120 is disposed between the first suction port 112 and the second suction port 113, and is positioned close to the second suction port 113. The water spray assembly 120 is configured to spray water onto the surface to be cleaned below the main body 110 of the device. The cleaning water sprayed by the water spray assembly 120 can be drawn into the floor brush duct 111 through the second suction port 113.

[0058] 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 edge of the first suction port 112 facing the second suction port 113. The second scraper 130b is located on the side of the second suction port 113 opposite to the first suction port 112.

[0059] It is understandable that, with the cleaning direction of the floor brush device 100 as a reference, the first scraper 130a is located behind the first suction port 112 and is positioned close to the first suction port 112; the second scraper 130b is located behind the second suction port 113 and is positioned close to the second suction port 113.

[0060] During the cleaning process, the first scraper 130a can block debris and impurities, while the first suction port 112 can suck in the debris and impurities; the second scraper 130b can rub and clean the surface to be cleaned, causing sewage and stains to collect. Combined with the negative pressure suction generated by the second suction port 113, a large negative pressure can be generated in the area, sucking the sewage into the second suction port 113. As the cleaning water passes over the surface to be cleaned, it will carry away dust and stains, achieving a good cleaning effect.

[0061] It should be noted that the floor brush device 100 provided in this application embodiment sucks up garbage and debris through the first suction port 112 to achieve the function of coarse suction, and sucks up the sewage after the water spray component 120 wets the ground through the second suction port 113 to achieve the function of fine washing, so as to achieve the effect of coarse suction followed by fine washing. With the cooperation of the first scraper 130a and the second scraper 130b, water stains can be avoided on the ground.

[0062] 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 second suction port 113, and the second scraper 130b or the first scraper 130a 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.

[0063] Please continue to refer to Figures 1 to 3 In some embodiments, a first end of a first scraper 130a is connected to a device body 110, and a second end of the first scraper 130a extends downward toward the device body 110. A first end of a second scraper 130b is connected to a device body 110, and a second end of the second scraper 130b extends downward toward the device body 110.

[0064] Understandably, when the floor brush device 100 cleans the surface to be cleaned, the second end of the first scraper 130a can contact the surface to be cleaned, or it can have a certain gap with the surface to be cleaned. The second end of the second scraper 130b can contact the surface to be cleaned, and there is a certain amount of interference between them, so that sewage and stains can accumulate in front of the second scraper 130b, and then be efficiently sucked into the floor brush air duct 111 under the suction of the second suction port 113, thereby improving cleaning efficiency.

[0065] 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 2 The Y direction is perpendicular to the X direction. The air inlet ends of the first suction port 112 and the second suction port 113 can both be set along the Y direction. The first suction port 112 can be in the shape of an outwardly flared trumpet, and the second suction port 113 can be in the shape of a long strip.

[0066] In some embodiments, the water spray assembly 120 extends along the length direction of the second suction port 113, thereby simultaneously wetting the position corresponding to the length direction of the first suction port 112 and increasing the cleaning area.

[0067] 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.

[0068] 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.

[0069] In some embodiments, the flow cross-sectional dimension of the first suction port 112 is larger than that of the second suction port 113. This ensures that the first suction port 112 can suck up garbage and debris, while enabling the second suction port 113 to generate a higher negative pressure suction force, thereby improving the suction efficiency of sewage.

[0070] Understandably, before the water spray assembly 120 wets and cleans the floor, dust, particulate matter, and some wastewater are sucked in through the first suction port 112 at the front end of the main body 110. The remaining stains and wastewater can pass through the first scraper 130a when the floor brush device 100 moves forward, and are thus cleaned by the water sprayed by the water spray assembly 120, and sucked into the floor brush air duct 111 by the second suction port 113, achieving the effect of coarse suction followed by fine cleaning.

[0071] In some embodiments, in the vertical direction, the lower edge of the first scraper 130a is higher than the lower edge of the second scraper 130b.

[0072] When the floor brush device 100 cleans the surface to be cleaned, the lower edge of the first scraper 130a has a gap with the surface to be cleaned, and the lower edge of the second scraper 130b abuts against and bends against the surface to be cleaned. After the first suction port 112 sucks in the debris, the remaining water stains can pass through the first scraper 130a and be sucked in by the second suction port 113, improving cleaning efficiency while preventing the second suction port 113 from being blocked.

[0073] In this embodiment, a third suction port 114 may also be provided on the main body 110 of the device, and the third suction port 114 is connected to the floor brush air duct 111. The third suction port 114 is located on the side of the water spray assembly 120 away from the second suction port 113.

[0074] It is understandable that the third suction port 114 and the second suction port 113 are distributed on the front and rear sides of the water spray assembly 120 and are located close to the water spray assembly 120. In this way, when the water spray assembly 120 sprays cleaning water to wet the ground, the second suction port 113 and the third suction port 114 can simultaneously suck in sewage on both sides, so as to quickly clean the ground and avoid sewage residue.

[0075] It should be noted that, compared to the second suction port 113 and the third suction port 114, the first suction port 112 is located closer to the front end of the device body 110, meaning that the first suction port 112, the third suction port 114, and the second suction port 113 are arranged sequentially from front to back. The second suction port 113 and the third suction port 114 are used in conjunction with the water spray assembly 120 to achieve a fine washing effect; while the first suction port 112, used for coarse suction, can have a larger distance from the third suction port 114, or it can be located close to the third suction port 114. Different examples will be used to illustrate this in detail below.

[0076] First, an example of a gap between the first suction port 112 and the third suction port 114 will be explained.

[0077] Please refer to Figures 1 to 3 In one possible implementation, the first suction port 112 and the third suction port 114 are separately arranged and have a certain distance between them. The first scraper 130a, which is located on the rear edge of the first suction port 112, also has a certain distance between it and the third suction port 114.

[0078] The floor brush device 100 may also include a third scraper 130c, which is located on the side edge of the third suction port 114 away from the second suction port 113.

[0079] It is understandable that a narrow cleaning chamber can be formed between the second scraper 130b and the third scraper 130c. The second suction port 113, the water spray assembly 120, and the third suction port 114 are arranged in sequence to correspond to the cleaning chamber. The cleaning chamber has a relatively sealed space, thereby forming a large negative pressure suction force and improving the sewage suction efficiency of the second suction port 113 and the third suction port 114.

[0080] For example, the cleaning cavity formed between the second scraper 130b and the third scraper 130c extends along the width direction of the device body 110, that is, along the Y direction. The air inlet of the cleaning cavity can be located at both ends of the width direction of the device body 110. After the airflow enters the cleaning cavity from both ends of the device body 110, it will flow towards the middle. At the same time, the airflow can drive the cleaning water on the surface to be cleaned to converge towards the middle. In this process, the flowing cleaning water can have a rinsing effect on the surface to be cleaned.

[0081] 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.

[0082] Please refer to Figures 1 to 5In some embodiments, at least one of the second scraper 130b and the third scraper 130c 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.

[0083] When the water-passing surface 132 comes into contact with the surface to be cleaned, a water-passing channel 1321 is formed between the water-passing surface 132 and the surface to be cleaned; when the sealing surface 131 comes into contact with the surface to be cleaned, the sealing surface 131 and the surface to be cleaned are relatively sealed.

[0084] Understandably, the scraper 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, causing the wastewater to collect on the side facing the suction port and be sucked in by the suction port, thus improving cleaning efficiency. On the other hand, it can also contact the surface to be cleaned through the water-passing surface 132, 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 to be cleaned and achieving a better cleaning effect.

[0085] In some embodiments, both the second scraper 130b and the third scraper 130c have a sealing surface 131 and a water-passing surface 132.

[0086] Along the cleaning direction 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; the sealing surface 131 of the third scraper 130c faces the rear of the floor brush device 100, and the water-passing surface 132 of the third scraper 130c faces the front of the floor brush device 100. When the floor brush device 100 reciprocates for cleaning, wastewater flowing in the direction of movement can pass through the scrapers and be sucked into the second suction port 113 and the third suction port 114.

[0087] Understandably, when the brush device 100 moves forward in the X direction, both the second scraper 130b and the third scraper 130c bend backward relative to the main body 110 in the cleaning direction. At this time, the water-passing surface 132 of the third scraper 130c contacts the surface to be cleaned, allowing the wastewater from the surface to be cleaned in the cleaning direction to pass through the front third scraper 130c and enter below the third suction port 114, where it is sucked into the third suction port 114. Meanwhile, the sealing surface 131 of the rear second scraper 130b contacts the surface to be cleaned, acting as a scraper to prevent water stains from remaining.

[0088] When the ground brush device 100 moves backward in the X direction, both the second scraper 130b and the third scraper 130c bend forward relative to the device body 110 in the cleaning direction. At this time, the sealing surface 131 of the third scraper 130c 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, thus preventing water stains from being generated when dragging backward and improving the cleaning effect.

[0089] For example, the water-passing surface 132 has an uneven structure. Along the length of the scraper, the uneven structure is arranged from one end of the scraper to the other. 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.

[0090] For example, the concave-convex structure includes a plurality of protrusions 1322, which are spaced apart along the length of the scraper. 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.

[0091] 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.

[0092] It should be noted that in the floor brush device 100 provided in this application embodiment, the second suction port 113 and the third suction port 114 can be in the form of parallel elongated structures, so that the second suction port 113 and the third suction port 114 have strong negative pressure suction to suck up sewage, play a good cleaning role, and avoid water stains.

[0093] 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.

[0094] In other embodiments, the side of the second scraper 130b facing the second suction port 113 and the side away from the second suction port 113 are both sealing surfaces 131; the side of the third scraper 130c facing the third suction port 114 and the side away from the third suction port 114 are both sealing surfaces 131.

[0095] Understandably, the sealing surface 131 can improve the sealing effect of the cleaning chamber between the second scraper 130b and the third scraper 130c, so that the sewage is collected in the area below the second suction port 113 and the third suction port 114, avoiding water stains.

[0096] The following describes an example of the first suction port 112 and the third suction port 114 being arranged adjacent to each other.

[0097] Figure 6 This is another structural schematic diagram of the floor brush device provided in the embodiments of this application.

[0098] Please refer to Figure 6 and combined Figure 4 and Figure 5 In one possible implementation, the floor brush duct 111 has an air inlet end, and the first scraper 130a, the second suction port 113 and the third suction port 114 are all located at the air inlet end of the floor brush duct 111.

[0099] In this design, a first suction port 112 is formed between the front side of the first scraper 130a along the cleaning direction of the floor brush device 100 and the front side of the air inlet. A second suction port 113 is formed between the second scraper 130b and the water spray assembly 120. A third suction port 114 is formed between the water spray assembly 120 and the first scraper 130a. In this way, the first suction port 112 used for coarse cleaning and the second and third suction ports 113 and 114 used for fine cleaning can be placed as close as possible to avoid water stains.

[0100] For example, the first scraper 130a may have a structure with a water-passing surface 132, which is located on the front side, i.e., the side facing the first suction port 112. When the floor brush device 100 moves forward, the first scraper 130a bends backward, and the water-passing surface 132 contacts the surface to be cleaned. The first suction port 112 can suck in garbage and sewage. A small amount of residual sewage can pass through the water passage 1321 of the water-passing surface 132 and then be sucked into the floor brush air duct 111 by the second suction port 113 and the third suction port 114.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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, a first suction port, and a second suction port, both of which are connected to the floor brush air duct. Along the cleaning direction of the floor brush device, the first suction port is located in front of the second suction port; the first scraper is located on the edge of the first suction port facing the second suction port; the second scraper is located on the side of the second suction port away from the first suction port; the water spray assembly is disposed between the first and second suction ports, and is positioned close to the second suction port. The water spray assembly is configured to spray water onto the surface to be cleaned below the main body of the device, achieving a coarse suction followed by a fine cleaning effect. Combined with the first and second scrapers, water stains can be avoided on the floor, thus eliminating the need for a roller brush structure. After cleaning, drying is not required, and no odor is generated.

[0106] 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.
