Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a floor brush and cleaning equipment. Background Technology

[0002] As people's demand for home cleaning increases, cleaning equipment such as floor scrubbers and all-in-one sweepers and mops are becoming increasingly popular. These cleaning devices can assist in cleaning work, improve cleaning results, and meet people's needs for convenient and efficient cleaning.

[0003] Taking floor scrubbers as an example, some floor scrubbers currently have an auxiliary cleaning device on the front, which can be raised and lowered relative to the ground. During cleaning, when the user pushes the scrubber forward, the auxiliary cleaning device rises to a suspended position, at which point the squeegee is a certain distance from the ground to ensure the scrubber's ability to suck up large particles of debris. When the user pulls the scrubber backward, the auxiliary cleaning device descends to the cleaning position, at which point the squeegee can scrape away debris from the ground. However, when using this type of floor scrubber, if the user adjusts the angle of the scrubber, such as when maneuvering it to turn, water stains may remain on the ground at the end of the scrubber, affecting the cleaning effect. Utility Model Content

[0004] In view of the above problems, this application provides a floor brush and a cleaning device.

[0005] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0006] A first aspect of this application provides a floor brush for a cleaning device, the floor brush comprising:

[0007] The floor brush body can move along a preset direction of travel on the surface to be cleaned;

[0008] A cleaning component, connected to the floor brush body, is used to clean the surface to be cleaned;

[0009] An auxiliary cleaning device is located on the front side of the cleaning component along the direction of travel. The auxiliary cleaning device is movably connected to the floor brush body to switch between a cleaning position and a suspended position relative to the surface to be cleaned.

[0010] The auxiliary cleaning device has water-blocking structures at both ends of the lateral direction perpendicular to the direction of travel. The front end of the water-blocking structure is connected to the auxiliary cleaning device, and the rear end of the water-blocking structure extends toward the cleaning component.

[0011] Taking a roller brush as an example, since the lateral length of the roller brush is usually slightly smaller than that of the auxiliary cleaning device, a small amount of water on the roller brush will flow to the ground through the auxiliary cleaning device. During this flow, the water will flow towards both ends of the auxiliary cleaning device, thus forming water stains at those ends. Because the roller brush is slightly shorter than the auxiliary cleaning device, it cannot clean the water stains on the ground at both ends of the auxiliary cleaning device. This solution addresses this by using a water-blocking structure on the left side of the auxiliary cleaning device to prevent water adhering to the roller brush from flowing out to its left end through the auxiliary cleaning device, and a water-blocking structure on the right side to prevent dirt from flowing out through the right end of the floor brush. This ensures that the length of the water stains on the ground matches the length of the roller brush. Thus, the two water-blocking structures at both ends of the auxiliary cleaning device effectively reduce residual water stains on the ground, and even less water remains when the device turns. Since the front end of the water-blocking structure is connected to the auxiliary cleaning device, dirt flowing along the auxiliary cleaning device towards its lateral ends is blocked by the water-blocking structure. The rear end of the water-blocking structure extends towards the cleaning component, which helps guide dirt towards the cleaning component and further reduces the risk of dirt flowing out laterally towards the outside of the floor brush.

[0012] Optionally, using a surface perpendicular to the direction of travel as a reference surface, the vertical projection of the water-blocking structure onto the reference surface is at least partially located within the vertical projection range of the cleaning component onto the reference surface; or, the vertical projection of the water-blocking structure onto the reference surface is at least partially flush with the vertical projection of the cleaning component onto the reference surface. This ensures that as much of the dirt blocked by the water-blocking structure as possible is located within the cleaning area of ​​the cleaning component, making it easier for the cleaning component to remove. Furthermore, guided by the water-blocking structure, the dirt can be brought closer to the suction port of the floor brush, making it easier to suck away.

[0013] Optionally, the auxiliary cleaning device includes a scraper, which is used to scrape off dirt from the surface to be cleaned when the auxiliary cleaning device is in the cleaning position; the water-blocking structure is disposed at both ends of the scraper.

[0014] During the cleaning process as the floor brush moves backward, the auxiliary cleaning device removes dirt from the floor by scraping off the squeegee. Wastewater mainly accumulates at the squeegee. Placing the water-blocking structure on both sides of the squeegee can effectively ensure the blocking effect of wastewater.

[0015] Optionally, the water-blocking structure and the auxiliary cleaning device together form a chamber with openings at both the bottom and rear. The water-blocking structure located at both ends of the scraper blade forms two side walls of the chamber, and the scraper blade forms the front side wall of the chamber. That is, there is no gap between the front end of the water-blocking structure and the auxiliary cleaning device, nor between the top of the water-blocking structure and the auxiliary cleaning device. During cleaning, when the auxiliary cleaning device is in the cleaning position, the ground covers the bottom opening of the chamber, while the cleaning component is located at the rear opening. Wastewater blocked by the water-blocking structure can be more effectively retained within the chamber. This retained wastewater can be carried away by the rotation of the roller brush or sucked away by suction.

[0016] Optionally, when the auxiliary cleaning device is in the cleaning position, there is a gap between the bottom of the water-blocking structure and the surface to be cleaned. This allows airflow to effectively pass through this gap inside and outside the suction chamber, and wastewater blocked by the water-blocking structure can be more effectively sucked away with the airflow. In other words, the aforementioned chamber will not have its suction power affected by being sealed.

[0017] Optionally, the vertical distance between the vertical projection of the rear end of the water-blocking structure on the horizontal plane and the vertical projection of the cleaning component on the horizontal plane is less than 10 mm, or the vertical projection of the rear end of the water-blocking structure on the horizontal plane is located within the range of the vertical projection of the cleaning component on the horizontal plane.

[0018] When there is a certain distance between the vertical projection of the rear end of the water-blocking structure on the horizontal plane and the vertical projection of the cleaning component on the horizontal plane, the water-blocking effect can be guaranteed, and the interference of the cleaning component on the auxiliary cleaning device during the process of rising or falling relative to the ground can be reduced or even avoided.

[0019] When the vertical projection of the rear end of the water-blocking structure onto the horizontal plane is within the vertical projection range of the cleaning component onto the horizontal plane, the rear end of the water-blocking structure can more effectively guide the sewage to the cleaning component, resulting in a better water-blocking effect.

[0020] Optionally, the water-blocking structure and the scraper are integrally formed.

[0021] The one-piece molding process facilitates manufacturing and ensures a reliable connection between the water-blocking structure and the scraper, thus guaranteeing better waterproofing. Generally, the auxiliary cleaning device includes a connector, with the scraper installed at the bottom of the connector. Since the scraper and the water-blocking structure are integrally molded, the installation and fixation of the water-blocking structure are simultaneously achieved after the scraper is installed on the connector, thereby simplifying the assembly operation of the floor brush.

[0022] Optionally, the vertical projection of the two water-blocking structures on the horizontal plane is either outward-pointing or inward-pointing.

[0023] The water-blocking structure only needs to prevent sewage from overflowing to both ends of the horizontal direction of the floor brush, and its shape and structure can be flexibly set.

[0024] The inward-pointing water-blocking structure tilts inward from front to back, and its front end can be closer to the horizontal limits of the auxiliary cleaning device, or even beyond the horizontal ends of the cleaning component. In this way, the entire horizontal length of the auxiliary cleaning device can be effectively used to scrape off dirt from the ground, and the scraped dirt can flow better along the water-blocking structure to the cleaning component.

[0025] Optionally, the water-blocking structure is a water-blocking plate. Water-blocking plates have a simple structure, which helps reduce manufacturing costs.

[0026] Optionally, the surface of the water-blocking structure can be a plane, an arc surface, or a combination of a plane and an arc surface. The water-blocking structure only needs to prevent sewage from overflowing to both ends of the floor brush laterally, and its surface shape can be flexibly set.

[0027] Optionally, the angle between the reference plane parallel to the baffle and the surface to be cleaned is 30-120°. Here, the reference plane refers to the surface with the largest surface area that is parallel to the baffle. The angle between the reference plane and the ground can be flexibly set as long as it can effectively block the outflow of sewage, and is not limited to the approximate 90° shown in the embodiments of this application.

[0028] A second aspect of this application provides a cleaning device, the cleaning device comprising:

[0029] The floor brush described in any embodiment of the first aspect;

[0030] The body is connected to the floor brush.

[0031] A clean water tank, installed on the machine body or the floor brush, is used to provide cleaning liquid for wetting the cleaning components.

[0032] The second aspect of this application has the same technical effects as the first aspect of the embodiment, and will not be described again. Attached Figure Description

The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

Therefore, a feature specified as "first" or "second" can explicitly include at least one of those features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc.

[0050] In this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "linking," "fixing," and "setting," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal communication of two components or the interaction between two components.

[0051] In this embodiment, "front" and "back" are relative to the parallel direction of travel. "Left" and "right" are relative to the perpendicular direction of travel, and are also the two ends in the lateral direction.

[0052] This application provides a cleaning device, see [link to relevant documentation] Figure 1 The cleaning device 100 includes a floor brush 110 and a body 120. During the cleaning process, the user can hold the device 120 and operate it to move the floor brush 110, causing it to rub against the surface to be cleaned. Surfaces to be cleaned include floors, carpets, walls, tabletops, etc.

[0053] Without limitation, the cleaning equipment 100 includes, but is not limited to, floor scrubbers, sweeping and mopping machines, and electric mops. For ease of description, the cleaning equipment 100 and the floor brush 110 of this application will be described below using a floor scrubber as an example and the surface to be cleaned as a ground surface.

[0054] Optionally, the cleaning device 100 also includes a clean water tank 130, which can store cleaning liquid. The floor brush 110 includes a cleaning component 40 disposed at its bottom. The clean water tank 130 can provide cleaning liquid to the cleaning component 40 to wet it, so that the cleaning component 40 can wet the stains on the surface to be cleaned during the cleaning process, reduce the adhesion of the stains, and improve the cleaning effect.

[0055] exist Figure 1 and Figure 3 In the illustrated implementation, the cleaning component 40 is a roller brush, which is rotatably connected to the floor brush body 10, and the number of roller brushes is one. In other implementations, the number of roller brushes can be two, three, or more. The cleaning component 40 can also be other forms such as a cleaning disc.

[0056] Depending on the specific usage requirements, the clean water tank 130 can be installed on the body 120 or on the floor brush 110.

[0057] In some embodiments, the cleaning device 100 further includes a wastewater tank 140 for collecting dirt generated during the cleaning process, which is generally a solid-liquid mixture. Similarly, the wastewater tank 140 may also be mounted on the body 120 or the floor brush 110.

[0058] In some embodiments, the cleaning device 100 may further include a suction device 150 that provides negative pressure, under which dirt on the surface to be cleaned is drawn into a wastewater tank 140. For example, the suction device 150 includes an impeller and a motor, the motor driving the impeller to rotate to generate negative pressure suction.

[0059] Generally, see Figure 4 The floor brush 110 is provided with a suction chamber 11 with an opening and a suction port connecting the suction chamber 11 and the wastewater tank 140. The suction device 150 draws dirt from the floor through the opening of the suction chamber 11 and through the suction port to the wastewater tank 140. The aforementioned cleaning component 40 is at least partially located within the suction chamber 11.

[0060] See Figure 1 and Figure 3The cleaning device 100 is also equipped with an auxiliary cleaning device 20, which is movable and can rise or fall relative to the ground during movement. During the cleaning process, the cleaning component 40 can clean most of the dirt on the ground. If stubborn stains or residual water stains are encountered, the auxiliary cleaning device 20 can be adjusted to a cleaning position to assist in cleaning stubborn stains or small amounts of residual water stains. Specifically, if the cleaning device 100 is pushed forward, the auxiliary cleaning device 20 can rise to a suspended position. At this time, there is a gap between the auxiliary cleaning device 20 and the ground to prevent the auxiliary cleaning device 20 from obstructing the removal of dirt on the ground in front. When the cleaning device 100 is pulled back, the auxiliary cleaning device 20 can descend to a cleaning position, and the auxiliary cleaning device 20 contacts the ground, allowing it to scrape or wipe away dirt on the ground, thereby improving the cleaning effect.

[0061] A drive unit can be installed on the floor brush 110 to drive the auxiliary cleaning device 20.

[0062] For example, the driving device includes a driving component and a transmission component. The driving component includes a motor, and the transmission component includes a gear transmission mechanism, a linkage transmission mechanism, etc.

[0063] The cleaning equipment 100 with auxiliary cleaning device 20 changes cleaning direction, for example: see Figure 2 When the floor brush 110 turns from the original cleaning path A to the path B to be cleaned, obvious water stains 200 will be generated on both sides of the floor brush 110, especially on the left side of the floor brush 110. Water stains 200 will be generated every time the angle of the floor brush 110 is adjusted, which affects the cleaning effect and reduces the user experience of the cleaning equipment 100.

[0064] Research has revealed that the reasons for the water stains 200 appearing when the floor brush 110 changes direction include, but are not limited to: see Figure 3 The lateral length of the auxiliary cleaning device 20 is greater than the lateral length of the cleaning component 40. As a result, when the floor brush 110 turns, the wastewater on the side of the auxiliary cleaning device 20 facing the cleaning component 40 will flow out beyond the lateral ends of the floor brush 110. The wastewater that flows out is outside the area that the cleaning component 40 can clean, and thus remains on the ground.

[0065] To improve the aforementioned problem of water stain residue, this application provides the following technical solutions. The following is in conjunction with… Figures 3 to 11 The technical solutions of the embodiments of this application will be described in detail.

[0066] See Figure 3This application provides a floor brush 110, which includes a floor brush body 10, a cleaning component 40, an auxiliary cleaning device 20, and a water-blocking structure 30. The floor brush body 10 can move along a preset travel direction on the surface to be cleaned. The cleaning component 40 is connected to the floor brush body 10 and is used to clean the surface to be cleaned. The auxiliary cleaning device 20 is located in front of the cleaning component 40 along the travel direction and is movably connected to the floor brush body 10 to switch between at least a cleaning position and a suspended position relative to the surface to be cleaned. The auxiliary cleaning device 20 has water-blocking structures 30 at its two transverse ends perpendicular to the travel direction. The front end of the water-blocking structure 30 is connected to the auxiliary cleaning device 20, and the rear end of the water-blocking structure 30 extends toward the cleaning component 40. The water-blocking structure 30 is used to prevent liquid from overflowing to the two transverse ends of the cleaning component 40 to form residual water stains when the auxiliary cleaning device 20 is in the cleaning position.

[0067] Taking the roller brush as an example, the lateral length of the cleaning component 40 is usually slightly smaller than that of the auxiliary cleaning device 20. A small amount of water on the roller brush will flow to the ground via the auxiliary cleaning device 20. During this flow, the water will move towards both ends of the auxiliary cleaning device 20, forming water stains at these ends. Because the roller brush is slightly shorter than the auxiliary cleaning device 20, it cannot clean the water stains on the ground at both ends. This solution addresses this by using a water-blocking structure 30 at the left end of the auxiliary cleaning device 20 to prevent dirt (mainly sewage) from flowing out through the left end of the floor brush 110; and a water-blocking structure 30 at the right end of the auxiliary cleaning device 20 to prevent dirt from flowing out through the right end of the floor brush 110, thus matching the length of the water stains on the ground with the length of the roller brush. In this way, the two water-blocking structures 30 at both ends of the auxiliary cleaning device 20 effectively reduce residual water stains on the ground, resulting in even less residual water stains when the device turns. Since the front end of the water-blocking structure 30 is connected to the auxiliary cleaning device 20, dirt is blocked by the water-blocking structure 30 when it flows along the auxiliary cleaning device 20 to its lateral ends. The rear end of the water-blocking structure 30 extends towards the cleaning component 40, which helps the water-blocking structure 30 guide the dirt towards the cleaning component 40, further reducing the risk of dirt flowing out laterally towards the outer side of the floor brush 110.

[0068] In some alternative embodiments, see Figure 3 Using the surface perpendicular to the direction of travel as the reference surface M, Figure 3The reference plane M shown is perpendicular to the paper. The vertical projection of the water-blocking structure 30 onto the reference plane is at least partially within the vertical projection range of the cleaning component 40 onto the reference plane, or the vertical projection of the water-blocking structure 30 onto the reference plane is at least partially flush with the vertical projection of the cleaning component 40 onto the reference plane. Here, "flush" refers to the flushness at both ends in the horizontal direction. This ensures that as much of the dirt blocked by the water-blocking structure 30 as possible is located within the cleaning area of ​​the cleaning component 40, making it easier for the cleaning component 40 to remove it. Moreover, guided by the water-blocking structure 30, the dirt can be brought closer to the suction port of the brush 110, making it easier to be sucked away.

[0069] exist Figure 3 and Figure 4 In the implementation shown, the vertical projection of the water-blocking structure 30 onto the reference plane is located within the vertical projection range of the cleaning component 40 onto the reference plane. Specifically, the front end of the water-blocking structure 30 extends to both lateral ends of the cleaning component 40. Figures 4 to 6 The two dashed lines indicate the locations outside the two lateral ends of the cleaning component 40; the rear end of the water-blocking structure 30 is located between the two lateral ends of the cleaning component 40.

[0070] exist Figure 5 In the implementation shown, the vertical projection of the water-blocking structure 30 onto the reference plane is entirely within the vertical projection range of the cleaning component 40 onto the reference plane. Specifically, the front and rear ends of the water-blocking structure 30 are located between the two lateral ends of the cleaning component 40.

[0071] exist Figure 6 In the illustrated implementation, the vertical projection of the water-blocking structure 30 onto the reference plane is flush with the vertical projection of the cleaning component 40 onto the reference plane. Specifically, the front end of the water-blocking structure 30 is flush with both lateral ends of the cleaning component 40; the rear end of the water-blocking structure 30 is located between the lateral ends of the cleaning component 40. In other implementations, the rear end of the water-blocking structure 30 may also be flush with both lateral ends of the cleaning component 40.

[0072] In some alternative embodiments, see Figure 3 The auxiliary cleaning device 20 includes a scraper 21, which is used to scrape away dirt from the surface to be cleaned when the auxiliary cleaning device 20 is in the cleaning position. A water-blocking structure 30 is disposed at both ends of the scraper 21. During the cleaning process as the floor brush 110 moves backward, the auxiliary cleaning device 20 relies on the scraper 21 to remove dirt from the floor. Wastewater mainly accumulates at the scraper 21. Distributing the water-blocking structure 30 on both sides of the scraper 21 effectively ensures the blocking effect on wastewater.

[0073] The scraper 21 extends laterally, and the water-blocking structure 30 is located between the scraper 21 and the cleaning component 40. Figure 3In the implementation shown, the cleaning component 40 is a roller brush, which is rotatably connected to the floor brush body 10; the lateral length of the scraper 21 is greater than the axial length of the roller brush, so that the scraper 21 can scrape off dirt over a larger area.

[0074] In some implementations, the auxiliary cleaning device 20 includes a wiping plate, and a water-blocking structure 30 may also be provided at both ends of the wiping plate and located between the wiping plate and the cleaning component 40. The wiping plate has a higher hardness than the scraper 21, and can more effectively remove stubborn stains from the floor.

[0075] See Figure 10 In some other implementations, the auxiliary cleaning device 20 includes a scraper 21 and a wiping plate 23. The wiping plate 23 is located between the scraper 21 and the cleaning component 40. In this case, the lateral length of the wiping plate 23 can be set to be less than the lateral length of the scraper 21. The front end of the water-blocking structure 30 is connected to the scraper 21, and the rear end of the water-blocking structure 30 can extend beyond the lateral ends of the wiping plate 23 and into the cleaning component 40. This ensures both the auxiliary cleaning functions of the wiping plate 23 and the scraper 21, and also effectively guarantees the water-blocking effect of the water-blocking structure 30, reducing or even preventing sewage from flowing out along the wiping plate 23 to its lateral ends. This is more suitable for situations where the scraper 21 and the wiping plate 23 rise and fall synchronously relative to the ground. Of course, water-blocking structures 30 can also be provided at both lateral ends of the wiping plate 23 and the scraper 21. In this way, whether the scraper 21 and the wiping plate 23 rise and fall separately relative to the ground or both rise and fall synchronously relative to the ground, the water-blocking effect can be effectively guaranteed.

[0076] In some alternative embodiments, see Figure 7 The water-blocking structure 30 and the auxiliary cleaning device 20 together form a chamber 13 with openings at the bottom and rear. The water-blocking structures 30 located at both ends of the scraper 21 form the two side walls of the chamber 13, while the scraper 21 forms the front side wall. In other words, there is no gap between the front end of the water-blocking structure 30 and the auxiliary cleaning device 20, nor between the top of the water-blocking structure 30 and the auxiliary cleaning device 20. During cleaning, when the auxiliary cleaning device 20 is in the cleaning position, the ground covers the bottom opening of the chamber 13, while the cleaning component 40 is located at the rear opening of the chamber 13. Wastewater blocked by the water-blocking structure 30 can be more effectively trapped within the chamber 13. This trapped wastewater can be carried away by the rotation of the roller brush or sucked away by suction.

[0077] In some alternative embodiments, when the auxiliary cleaning device 20 is in the cleaning position, there is a gap between the bottom of the water-blocking structure 30 and the surface to be cleaned. This allows airflow to effectively pass through this gap inside and outside the suction chamber 11, and wastewater blocked by the water-blocking structure 30 can be more effectively sucked away with the airflow. In other words, the suction force is not affected by the bottom of the aforementioned chamber 13 being sealed off by the ground. Without limitation, the "gap" here can be within 3mm or 5mm.

[0078] In some alternative embodiments, see Figure 4 The front end of the water-blocking structure 30 is connected to the scraper 21, and the rear end of the water-blocking structure 30 extends toward the cleaning component 40; the vertical distance L between the vertical projection of the rear end of the water-blocking structure 30 on the horizontal plane and the vertical projection of the cleaning component 40 on the horizontal plane is less than 10mm.

[0079] Figure 4 This is a top view of the structure of part 110 of the ground brush, showing... Figure 3 The relative positional relationship between the scraper 21 and the roller brush. Figure 4 In the implementation shown, the vertical distance between the rear end of the water-blocking structure 30 and the roller brush (i.e., the vertical distance L between the vertical projection of the rear end of the water-blocking structure 30 on the horizontal plane and the vertical projection of the cleaning component 40 on the horizontal plane) is approximately 2.2 mm. Having a certain distance between the vertical projection of the rear end of the water-blocking structure 30 on the horizontal plane and the vertical projection of the cleaning component 40 on the horizontal plane ensures the water-blocking effect and reduces or even avoids interference from the cleaning component 40 during the upward or downward movement of the auxiliary cleaning device 20 relative to the ground.

[0080] In some implementations, the vertical projection of the rear end of the water-blocking structure 30 onto the horizontal plane falls within the range of the vertical projection of the cleaning component 40 onto the horizontal plane. In this case, the rear end of the water-blocking structure 30 can more effectively guide sewage to the cleaning component 40, resulting in a better water-blocking effect.

[0081] In some alternative embodiments, see Figure 8 The water-blocking structure 30 and the scraper strip 21 are integrally molded. This integral molding facilitates manufacturing and ensures a reliable connection between the water-blocking structure 30 and the scraper strip 21, thus guaranteeing better waterproofing. See also... Figure 7 The auxiliary cleaning device 20 includes a connector 22 connected to the aforementioned drive component. A scraper 21 is installed at the bottom of the connector 22. Since the scraper 21 and the water-blocking structure 30 are integrally formed, the installation and fixation of the water-blocking structure 30 are also realized simultaneously after the scraper 21 is installed, thus simplifying the assembly operation of the brush 110.

[0082] For example, the scraper strip 21 and the water-blocking structure 30 can be integrally formed by injection molding, blow molding, extrusion or machining.

[0083] The scraper 21 can be made of soft material, such as silicone or rubber.

[0084] In some alternative embodiments, the vertical projection of the two water-blocking structures 30 onto the horizontal plane can be Figure 3 The figure-eight shape is shown. In other embodiments, the vertical projection of the two water-blocking structures 30 onto the horizontal plane can also be an outward figure-eight shape or other shapes.

[0085] See Figure 3 The inward-pointing water-blocking structure 30 is inclined from front to back and inward. Its front end can be closer to the extreme positions of the two lateral ends of the auxiliary cleaning device 20, or even beyond the two lateral ends of the cleaning component 40. In this way, the lateral length of the auxiliary cleaning device 20 can be effectively used to scrape off dirt from the ground, and the scraped dirt can flow better along the water-blocking structure 30 to the cleaning component 40.

[0086] In some alternative embodiments, the water-blocking structure 30 is a water-blocking plate. The water-blocking plate has a simple structure, which helps to reduce manufacturing costs.

[0087] In some alternative embodiments, the surface of the water-blocking structure 30 is a plane, an arc surface, or a combination of a plane and an arc surface. The water-blocking structure 30 only needs to prevent sewage from overflowing to both ends of the floor brush 110 laterally, and its shape can be flexibly set, and is not limited to the shape mentioned in the embodiments of this application.

[0088] Figure 3 , Figure 7 and Figure 8 In the implementation shown, the water-blocking structure 30 is an inclined plate that is approximately perpendicular to the horizontal plane, with a flat surface and a relatively thin thickness. Figure 11 In the implementation shown, the water-blocking structure 30 is a concave arc surface in the lateral direction. In other implementations, the water-blocking structure 30 can also be a concave arc surface in the lateral direction, i.e., the concavity direction is the same as... Figure 11 on the contrary.

[0089] In some optional embodiments, the angle between the reference plane parallel to the baffle and the surface to be cleaned is 30-120°. The baffle is a relatively thin plate, with its surface having the largest surface area positioned along the front-to-back direction. Here, the reference plane refers to the surface with the largest surface area parallel to the baffle. The angle between the reference plane and the ground can be flexibly set as long as it effectively prevents sewage from flowing out, and is not limited to this. Figure 3 and Figure 9 The angle shown is approximately 90°. The angle between the reference plane and the ground can also be 60°, 80°, 100°, or 120°, etc.
