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, while the roller brush on the rear side rolls on the floor to achieve a wet mopping cleaning effect.

[0004] However, there is currently a large gap between the suction port on the front and the roller brush on the back of the cleaning equipment, which can easily leave water stains during the back-and-forth cleaning process. Utility Model Content

[0005] This application provides a floor brush device and cleaning equipment to solve the technical problem that the large gap between the suction port on the front side and the roller brush on the rear side of the current cleaning equipment makes it easy for water stains to remain during the reciprocating drag cleaning process.

[0006] In a first aspect, this application provides a floor brush device, which includes a device body, a water spraying assembly, a first scraping component, and a second scraping component; the device body has a floor brush air duct, and the floor brush air duct has an air intake area facing downwards from the device body;

[0007] Along the cleaning direction of the floor brush device, the second scraper is located at the rear edge of the air intake area; the first scraper is located in front of the second scraper and is disposed within the air intake area; a first suction port is formed between the first scraper and the front edge of the air intake area; the water spray assembly is disposed between the first scraper and the second scraper, and a second suction port is formed between the water spray assembly and at least one of the first scraper and the second scraper.

[0008] A second suction port is formed between the water spray component and the first scraper, and a third suction port is formed between the water spray component and the second scraper.

[0009] This application provides a floor brush device, which includes a device body, a water spray assembly, a first scraper and a second scraper; the device body has a floor brush air duct, and the floor brush air duct has an air intake area facing downwards from the device body;

[0010] Along the cleaning direction of the floor brush device, the second scraper is located at the rear edge of the air intake area; the first scraper is located in front of the second scraper and is disposed in the air intake area; a first suction port is formed between the first scraper and the front edge of the air intake area; the water spray assembly is disposed between the first scraper and the second scraper, a second suction port is formed between the water spray assembly and the first scraper, and a third suction port is formed between the water spray assembly and the second scraper.

[0011] The floor brush device provided in this application divides the air intake area into a first suction port, a second suction port, and a third suction port arranged in a front-to-back manner by setting a water spray component, a first scraper, and a second scraper in the air intake area of ​​the floor brush air duct. The first suction port is in front and is used to suck up garbage and debris to achieve a coarse suction function. The second and third suction ports are in the back and are used in conjunction with the water spray component to achieve a fine cleaning function. The coarse suction and fine cleaning areas are adjacent to each other, which can avoid water stains on the ground while achieving high cleaning efficiency.

[0012] As an optional implementation, both the first and second scraping members protrude downward toward the lower part of the device body.

[0013] When the floor brush device cleans the surface to be cleaned, both the first scraper and the second scraper are in contact with the surface to be cleaned, and a cleaning cavity is formed between the first scraper and the second scraper; both the second suction port and the third suction port are connected to the cleaning cavity.

[0014] With this configuration, the suction from the second and third suction ports makes it easier to create a larger negative pressure in the cleaning chamber, efficiently drawing the wastewater between the first and second scraper components into the floor brush duct and improving cleaning efficiency.

[0015] As an optional implementation, the second suction port and the third suction port are arranged at intervals along the cleaning direction of the floor brush device; the second suction port and the third suction port are arranged in parallel and extend along the width direction of the device body; wherein, the width direction of the device body is perpendicular to the cleaning direction of the floor brush device.

[0016] With this configuration, the second and third suction ports are positioned one in front of the other to simultaneously draw in wastewater, preventing water stains from remaining.

[0017] As an optional implementation, the length of both the second and third suction ports is matched with the width of the main body of the device.

[0018] This configuration allows the cleaning range of the second and third suction ports to cover different positions along the width of the device.

[0019] As an optional implementation, along the cleaning direction of the floor brush device, the width of the first suction port is greater than the width of the second suction port and the width of the third suction port.

[0020] This design ensures that large volumes of waste can be sucked in through the first suction port, while the second and third suction ports are relatively narrow to create higher negative pressure and airflow velocity to suck in sewage and avoid water stains.

[0021] As an optional implementation, the water spray assembly includes a water spray housing having water spray holes facing downwards from the main body of the device.

[0022] The water spray housing is disposed in the air inlet area, the water spray housing extends along the width direction of the main body of the device, and the length of the water spray housing matches the length of the second suction port and the third suction port.

[0023] This setup allows for simultaneous wetting of the areas corresponding to the length of both the second and third suction ports, increasing the cleaning area.

[0024] As an optional implementation, there are multiple water spray holes, which are arranged at intervals along the length of the water spray housing.

[0025] This design allows the sprayed cleaning water to rinse the floor and remove dust and stains when sewage is drawn in through the second and third suction ports, resulting in a better cleaning effect.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] As an optional implementation, both the first scraper and the second scraper have the sealing surface and the water-passing surface; the sealing surface of the first scraper faces the rear side of the floor brush device, and the water-passing surface of the first scraper faces the front side of the floor brush device; 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.

[0030] With this design, when the floor brush device moves back and forth to clean, whether it is pushed forward or pulled back, the wastewater can pass through the scraper and be sucked into the second and third suction ports, avoiding water stains.

[0031] The first scraper has a sealing surface and a water-passing surface. The sealing surface of the first scraper faces the rear side of the floor brush device, and the water-passing surface of the first scraper faces the front side of the floor brush device. The second scraper has sealing surfaces facing both the front and rear sides of the floor brush device.

[0032] This configuration allows for one-sided water flow in the cleaning chamber between the first and second scrapers, ensuring that wastewater not promptly sucked in by the first suction port can pass through the second scraper and be drawn in by the second and third suction ports, thus preventing water residue.

[0033] 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.

[0034] 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 with an air intake area facing downwards from the main body. Along the cleaning direction of the floor brush device, the second scraper is located at the rear edge of the air intake area. The first scraper is located in front of the second scraper and is disposed in the air intake area. A first suction port is formed between the first scraper and the front edge of the air intake area. The water spray assembly is disposed between the first and second scrapers, forming a second suction port between the water spray assembly and the first scraper, and a third suction port between the water spray assembly and the second scraper. The first suction port is in front for sucking up debris to achieve a coarse suction function, while the second and third suction ports are in the rear, working with the water spray assembly to achieve a fine cleaning function. The coarse suction and fine cleaning areas are adjacent to each other, which can avoid water stains on the ground while achieving high cleaning efficiency.

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.

[0049] 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.

[0050] 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.

[0051] 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, which supplies water to wet the roller brush. The floor brush adopts a front suction and rear mopping structure. The suction port on the front can suck up debris and dirt on the floor, while the roller brush on the rear rolls on the floor to achieve a wet mopping cleaning effect.

[0052] However, in current cleaning equipment, there is a large gap between the front suction port and the rear roller brush, which easily leaves water stains during the back-and-forth cleaning process, resulting in poor cleaning effect.

[0053] 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.

[0054] To address the aforementioned technical problems, this application provides a floor brush device and cleaning equipment. By dividing the air inlet of the floor brush duct into two distinct areas using a scraper, the front and rear areas are used for coarse suction and fine cleaning, respectively. During the cleaning process, the coarse suction port sucks up debris and dirt, while the water spray component, located in the fine cleaning area, wets the cleaned floor. The fine cleaning port sucks up the wastewater generated during cleaning into the device. As the cleaning water enters the fine cleaning port from the surface to be cleaned, it can remove dust and stains, improving cleaning efficiency. At the same time, the coarse suction and fine cleaning areas are adjacent to each other, which can prevent water stains from remaining after cleaning.

[0055] The following section provides examples illustrating the application scenarios of the floor brush device and cleaning equipment provided in the embodiments of this application.

[0056] 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.

[0057] 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 bottom schematic diagram of the floor brush device provided in an embodiment of this application.

[0058] 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.

[0059] The device body 110 has a floor brush air duct 111. The floor brush air duct 111 has an air intake area facing the lower part of the device body 110. When the floor brush device 100 performs cleaning operation on the surface to be cleaned, the air intake area generates negative pressure suction, and the airflow can carry dust and debris from the air intake area into the floor brush air duct 111.

[0060] In some embodiments, the floor brush device 100 includes a first scraping member 130a and a second scraping member 130b.

[0061] Along the cleaning direction of the floor brush device 100, the second scraper 130b is located at the rear edge of the air intake area. The first scraper 130a is located in front of the second scraper 130b and is disposed in the air intake area. A first suction port 112 is formed between the first scraper 130a and the front edge of the air intake area.

[0062] The water spray assembly 120 is disposed between the first scraper 130a and the second scraper 130b, and a second suction port 113 is formed between the water spray assembly 120 and at least one of the first scraper 130a and the second scraper 130b.

[0063] A water spray assembly 120 is disposed between the first scraper 130a and the second scraper 130b. A second suction port 113 is formed between the water spray assembly 120 and the first scraper 130a, and a third suction port 114 is formed between the water spray assembly 120 and the second scraper 130b. The water spray assembly 120 sprays water onto the surface to be cleaned below the main body 110 of the device to achieve a cleaning effect. The cleaning water sprayed by the water spray assembly 120 can be sucked into the floor brush duct 111 through the second suction port 113 and the third suction port 114.

[0064] Understandably, the first scraper 130a serves as a separator in the air intake area, dividing it into two regions: a front suction port 112 and a rear suction port 113 and a third suction port 114, which are further divided by the water spray assembly 120. Thus, the first suction port 112, the second suction port 113, and the third suction port 114 are arranged from front to back along the cleaning direction of the floor brush device 100.

[0065] It should be noted that in the floor brush device 100 provided in this application embodiment, the water spray component 120 and the first scraper 130a together play a separating role in the air intake area of ​​the floor brush air duct 111, while the second scraper 130b plays a scraping role on the rear side of the air intake area, dividing the air intake area into a first suction port 112, a second suction port 113 and a third suction port 114 arranged in front and behind. The first suction port 112 is in front and is used to suck up large-volume garbage and debris to achieve a coarse suction function. The second suction port 113 and the third suction port 114 are in the rear and work with the water spray component 120 to achieve a fine cleaning function, which can remove stubborn dust and stains attached to the ground.

[0066] Furthermore, since the two functional areas are separated by the first scraper 130a, that is, located on the front and rear sides of the first scraper 130a respectively, the coarse suction and fine cleaning areas are close to each other, which can avoid water stains on the ground while having high cleaning efficiency.

[0067] 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 third suction port 114, while the second scraper 130b and the first scraper 130a can scrape the surface to be cleaned, thus preventing water stains from remaining. Since no roller brush absorbs the wastewater, no wastewater remains on the floor brush device 100, preventing unpleasant odors from developing when the device is left idle after cleaning.

[0068] Please continue to refer to Figures 1 to 3 In some embodiments, the first scraper 130a and the second scraper 130b both protrude downward toward the device body 110.

[0069] For example, the first end of the first scraper 130a can be connected to the device body 110 via a scraper bracket, and the second end of the first scraper 130a can extend downward toward the device body 110. During the cleaning process, the second end of the first scraper 130a contacts the surface to be cleaned. Similarly, the first end of the second scraper 130b can be connected to the device body 110 via a scraper bracket, and the second end of the second scraper 130b can extend downward toward the device body 110. During the cleaning process, the second end of the second scraper 130b contacts the surface to be cleaned.

[0070] When the ground brush device 100 cleans the surface to be cleaned, both the first scraper 130a and the second scraper 130b are in contact with the surface to be cleaned, and a cleaning cavity is formed between the first scraper 130a and the second scraper 130b. The second suction port 113 and the third suction port 114 are both connected to the cleaning cavity.

[0071] Understandably, the cleaning chamber is positioned directly below the second suction port 113 and the third suction port 114. Under the suction force of the second suction port 113 and the third suction port 114, the cleaning chamber is more likely to form a large negative pressure, which can efficiently draw the sewage between the first scraper 130a and the second scraper 130b into the floor brush duct 111, thereby improving cleaning efficiency.

[0072] It should be noted that when the second ends of the first scraper 130a and the second scraper 130b come into contact with the surface to be cleaned, there is a certain amount of interference, which allows the first scraper 130a and the second scraper 130b to rub against the surface to be cleaned and act as scrapers. Sewage and stains can accumulate between the first scraper 130a and the second scraper 130b, and then be efficiently sucked into the floor brush duct 111 under the suction of the second suction port 113 and the third suction port 114, thereby improving cleaning efficiency.

[0073] 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, which is the orientation of the paper. The air inlet ends of the first suction port 112, the second suction port 113, and the third suction port 114 can all be arranged along the Y direction. For example, the first suction port 112 can be an outwardly flared trumpet-shaped structure, and the second suction port 113 and the third suction port 114 can be elongated strip-shaped structures.

[0074] In some embodiments, the second suction port 113 and the third suction port 114 are arranged at intervals along the cleaning direction of the floor brush device 100. The second suction port 113 and the third suction port 114 are arranged in parallel and extend along the width direction of the device body 110.

[0075] Understandably, the second suction port 113 and the third suction port 114 extend along the Y direction and have a slender structure. When negative pressure suction is generated, the airflow speed is relatively faster, and the airflow can more easily suck away water stains on the surface to be cleaned. In addition, the second suction port 113 and the third suction port 114 are distributed in front and behind, so they can suck in sewage at the same time to avoid water stains remaining.

[0076] For example, the lengths of the second suction port 113 and the third suction port 114 are matched with the width of the device body 110, thereby allowing the cleaning range of the second suction port 113 and the third suction port 114 to cover different positions in the width direction of the device. For instance, both the second suction port 113 and the third suction port 114 can extend from one side to the other in the width direction of the device body 110, and the lengths of the second suction port 113 and the third suction port 114 are approximately the width of the device body 110.

[0077] In some embodiments, along the cleaning direction of the floor brush device 100, the width of the first suction port 112 is greater than the width of the second suction port 113 and the width of the third suction port 114.

[0078] Understandably, the flow cross-sectional dimension of the first suction port 112 is larger than that of the second suction port 113 and the third suction port 114. Before the water spray assembly 120 wets and cleans the floor, dust, particulate matter, and some sewage are sucked in through the first suction port 112 at the front end of the main body 110. The remaining stains and sewage can pass through the first scraper 130a as the floor brush device 100 moves forward, and are thus cleaned by the water sprayed by the water spray assembly 120. The second suction port 113 and the third suction port 114 are relatively narrow to form a higher negative pressure and airflow velocity, which can quickly suck the sewage into the floor brush air duct 111, achieving the effect of coarse suction followed by fine cleaning.

[0079] In some embodiments, the water spray assembly 120 includes a water spray housing 121 and a water pump, the water pump being disposed on the device body 110, the water spray housing 121 having a water spray hole 122 facing downwards from the device body 110, and the water pump being configured to supply water to the water spray hole 122.

[0080] It is understood that a water tank may be provided on the main body 110 of the device or the cleaning equipment 10 on which the main body 110 is used. The water pump can draw the cleaning water in the water tank into the water spray assembly 120 and provide a certain water pressure so that the cleaning water is sprayed from the water spray hole 122 onto the surface to be cleaned.

[0081] A water spray housing 121 is disposed within the air intake area, with a first suction port 112 and a second suction port 113 separated on its front and rear sides. The water spray housing 121 extends along the width direction of the device body 110, and the length of the water spray housing 121 matches the lengths of the second suction port 113 and the third suction port 114. For example, the water spray housing 121 can extend from one side to the other in the width direction of the device body 110, with its length approximating the width dimension of the device body 110, thereby simultaneously wetting the positions corresponding to the length directions of the second suction port 113 and the third suction port 114, increasing the cleaning area.

[0082] In addition, the water spray assembly 120 may not require a water pump. When supplying water, gravity can be used to wet the ground by naturally dripping cleaning water from the spray hole 122.

[0083] For example, there can be multiple water spray holes 122, which are arranged at intervals along the length of the water spray housing 121, so that cleaning water can flow through all positions in the width direction of the device body 110. The embodiments of this application do not limit the specific size, shape and number of the water spray holes 122.

[0084] The structure of the first scraping component 130a and the second scraping component 130b will be described in detail below.

[0085] Figure 4A 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] In some embodiments, both the first scraper 130a and the second scraper 130b have a sealing surface 131 and a water-passing surface 132.

[0090] Along the cleaning direction of the floor brush device 100, 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, regardless of whether it is pushed forward or pulled backward, the wastewater can pass through the scraper and be sucked into the second suction port 113 and the third suction port 114, avoiding water stains.

[0091] Understandably, when the brush device 100 moves forward in the X direction, both the first scraper 130a and the second scraper 130b bend backward relative to the main 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 second suction port 113 and the third suction port 114, where it is sucked into them. 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.

[0092] 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, thus preventing water stains from being generated when dragging backward and improving the cleaning effect.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] In some embodiments, the first scraper 130a has a sealing surface 131 and a water-passing surface 132, with the sealing surface 131 of the first scraper 130a facing the rear side of the floor brush device 100 and the water-passing surface 132 of the first scraper 130a facing the front side of the floor brush device 100; the second scraper 130b has a sealing surface 131 facing both the front and rear sides of the floor brush device 100.

[0098] Understandably, only the first scraper 130a between the coarse suction area and the fine washing area adopts a water-permeable structure, which can achieve a one-sided water permeability effect in the cleaning chamber between the first scraper 130a and the second scraper 130b. This ensures that the sewage that the first suction port 112 does not suck in in time can pass through the second scraper 130b and be sucked in by the second suction port 113 and the third suction port 114, thus avoiding water stains.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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 with an air intake area facing downwards from the main body. Along the cleaning direction of the floor brush device, the second scraper is located at the rear edge of the air intake area. The first scraper is located in front of the second scraper and is disposed in the air intake area. A first suction port is formed between the first scraper and the front edge of the air intake area. The water spray assembly is disposed between the first and second scrapers, forming a second suction port between the water spray assembly and the first scraper, and a third suction port between the water spray assembly and the second scraper. The first suction port is in front for sucking up debris to achieve a coarse suction function, while the second and third suction ports are in the rear, working with the water spray assembly to achieve a fine cleaning function. The coarse suction and fine cleaning areas are adjacent to each other, which can avoid water stains on the ground while achieving high cleaning efficiency.

[0104] 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.
