Description

[0001] This application claims priority to Chinese patent application No. 202422390491.7, filed on September 29, 2024, entitled “Floor brush assembly and cleaning equipment”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cleaning equipment technology, and more particularly to a floor brush assembly and cleaning equipment. Background Technology

[0003] Vacuum cleaners are typically used to remove dust, debris, hair, and other trash from floors, meeting people's daily household cleaning needs. However, in daily life, there are sometimes water stains on the floor, and traditional vacuum cleaners cannot effectively clean areas with water stains.

[0004] To solve the aforementioned technical problems, floor scrubbers or manual mopping can typically be used to treat wet floors. However, floor scrubbers and mops are not very effective at handling dry dust and debris, are cumbersome to use, and floor scrubbers are relatively expensive, making them unsuitable for most households. Utility Model Content

[0005] This application provides a floor brush assembly and cleaning equipment to solve the problem that vacuum cleaners in the above-mentioned related technologies cannot handle floors with water stains.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a floor brush component, including:

[0008] Housing assembly, including a receiving cavity;

[0009] A roller brush is disposed within the receiving cavity and rotatably connected to the housing assembly. The roller brush is used to perform cleaning operations on the surface to be cleaned.

[0010] A water tank assembly is arranged radially spaced from the roller brush, and one end of the water tank assembly facing the roller brush is in communication with the receiving cavity portion. The water tank assembly is at least used to provide clean water to the roller brush.

[0011] A scraper assembly is provided at one end of the water tank assembly facing the roller brush. The minimum distance between the scraper assembly and the surface to be cleaned is a first distance. The ratio of the water supply rate (g / min) of the water tank assembly to the roller brush to the first distance (mm) is between 3 and 22.

[0012] The floor brush assembly provided in this application embodiment includes a housing assembly with a receiving cavity for mounting a roller brush. The roller brush allows for cleaning operations. A water tank assembly with an opening communicating with the receiving cavity allows debris and other contaminants to enter the water tank assembly through the opening.

[0013] By incorporating a scraper assembly positioned at the end of the water tank assembly facing the roller brush, dust, dirt, and debris are swept up from the floor as the roller brush rotates. The scraper assembly guides the debris to openings, ensuring efficient collection and optimizing cleaning results. It also prevents dust and debris from falling back onto the floor during cleaning, avoiding secondary contamination and improving overall cleaning efficiency.

[0014] There is an initial distance between the squeegee assembly and the surface to be cleaned. This prevents excessive friction between the squeegee assembly and the surface, thus avoiding damage to the floor, especially for wood floors or other fragile surfaces. It also reduces resistance between the squeegee assembly and the floor, making the brush assembly operate more smoothly and reducing user fatigue.

[0015] Furthermore, in existing wet floor cleaning technologies, the roller brush leaves a layer or streaks of water on the surface being cleaned during operation. Under current technology, increasing the water supply to the roller brush can enhance its cleaning ability. However, this increased water supply inevitably leads to a greater amount of water left on the surface. If this residual water is not treated, it negatively impacts the cleaning experience and may even pose safety hazards. Current technologies employ two solutions: First, creating low pressure within the equipment to introduce suction and draw in a mixture of solid, liquid, and gaseous waste for recycling. Second, setting the scraper blade to be in contact with or press against the floor, forcefully scraping the residual water to the roller brush, where its rotation drives the water's recovery. Solution one significantly increases the size and weight of the cleaning equipment. Solution two increases the risk of scraper blade wear and floor damage, and the residual water is disturbed by the scraper blade, accumulating noticeable water streaks on the sides of the cleaning equipment, resulting in unsatisfactory cleaning performance.

[0016] This application provides a solution to improve or eliminate watermarks. On one hand, it appropriately reduces the water supply; on the other hand, it sets the squeegee assembly at a certain distance from the surface to be cleaned. Appropriately reducing the water supply keeps the residual water on the surface within an acceptable range for the user. Although some cleaning power is sacrificed, it significantly reduces the weight of the cleaning equipment, optimizes handling performance, and greatly reduces the difficulty of handling residual water on the floor. At this point, dirt and residual water on the surface to be cleaned are mainly wiped, rolled up, and collected by the roller brush, ensuring a suitable cleaning effect. Therefore, during the use of the cleaning equipment, the squeegee does not need to collect residual water in most cases. Furthermore, the squeegee can be raised to a certain gap, without disturbing the residual water layer on the surface to be cleaned, preventing the accumulation of residual liquid and the formation of watermarks. The smaller initial distance also ensures that the squeegee assembly is neither too close nor too far from the surface to be cleaned, effectively removing non-liquid dirt. This helps improve cleaning efficiency, achieving both the avoidance of watermarks and the cleaning of solid dirt, resulting in a cleaner floor.

[0017] As mentioned above, there is a certain correlation between the water supply volume M and the first distance H. If the water supply volume M is too large and the first distance H is too small, the problem of residual water on the ground still cannot be solved. If the water supply volume M is reduced, the first distance H does not need to be very large because the residual water on the ground is reduced. Otherwise, not only will the roller brush be unable to clean the dirt on the surface to be cleaned, but the scraper assembly will also be unable to remove solid dirt from the surface to be cleaned. Therefore, the ratio of water supply volume M to the first distance H needs to be controlled within a certain range.

[0018] Therefore, the improvement of this application based on the prior art lies in controlling the ratio of water supply M (g / min) to the first distance H (mm) between 3 and 22. In the embodiments of this application, the water supply M fluctuates between 8.5-11 (g / min), maintaining a certain cleaning effect of the roller brush while preventing excessive water from being left on the surface to be cleaned. The first distance H is controlled between 0.5-3 (mm) to prevent watermarks from forming. Therefore, the maximum value of the ratio of water supply M to the first distance H is 22. If this ratio exceeds 22, either the water supply increases or the first distance decreases, both of which will lead to the adverse consequences of residual water and watermarks on the ground. Similarly, the minimum value of the ratio of water supply M to the first distance H is 3. If this ratio is less than 3, either the water supply is too small to achieve the expected cleaning effect, or the first distance is too large to collect non-liquid dirt from the ground. In summary, the best cleaning effect can be achieved when the ratio of water supply M (g / min) to the first distance H (mm) is between 3 and 22.

[0019] In one possible implementation, the first distance is greater than 0.5 and less than or equal to 1 millimeter. This is also the most preferred range for the first distance.

[0020] This design further reduces the distance between the scraper assembly and the surface to be cleaned, thereby enhancing the scraper's ability to clean smaller diameter non-liquid contaminants on the surface and more effectively removing dust, dirt, and debris. This helps improve cleaning efficiency and makes the floor cleaner. As the first distance decreases, the water supply from the clean water tank to the roller brush also decreases synchronously to meet the maximum limit of the ratio of water supply to the first distance. Of course, too little water supply will also affect the wet cleaning ability of the roller brush, and the minimum limit of the ratio of water supply to the first distance must still be met.

[0021] In one possible implementation, the scraper assembly includes a scraper body; wherein,

[0022] The scraper body includes a connecting part and a bending part. The connecting part is used to connect with the water tank assembly, and the bending part extends toward the surface to be cleaned.

[0023] The bent portion can rotate and bend relative to the connecting portion in a direction parallel to the central axis of the roller brush.

[0024] By incorporating a scraper body to perform cleaning operations, and by including a connecting portion and a bending portion, the scraper body can be securely connected to the water tank assembly via the connecting portion. The bending portion, designed to rotate relative to the connecting portion, allows the scraper body to better conform to the contours of the surface to be cleaned, ensuring a more comprehensive and thorough cleaning. It also helps to scrape up dust, dirt, and debris of varying sizes from the surface, improving cleaning efficiency.

[0025] The bend design allows the squeegee to adapt to various types of surfaces, including uneven floors, carpets, and tile grout. It also reduces resistance between the squeegee and the surface to be cleaned, making it smoother during use, reducing user difficulty and fatigue, and minimizing excessive friction and pressure. This extends its lifespan, reduces wear and damage, and provides consistent cleaning results. Additionally, it reduces noise.

[0026] The flexible bend reduces friction and pressure on the floor, preventing scratches or damage, especially on wood floors or other vulnerable surfaces. The bend design also increases the flexibility of the squeegee body, enabling it to perform well in complex cleaning tasks.

[0027] In one possible implementation, the bending portion includes a thin-walled section and a folded section; wherein,

[0028] The thin-walled section is located between the folded section and the connecting portion, and the thin-walled section is used to fix the folded section and the connecting portion together.

[0029] The wall thickness of the thin-walled section is less than the wall thickness of the folded section, and less than the wall thickness of the end of the connecting portion that is connected to the thin-walled section.

[0030] This design allows for greater flexibility in the squeegee body's design by incorporating a thin-walled section and a folding section within the bending portion, creating a multi-segment structure with varying wall thicknesses. The thin-walled section has a thinner wall thickness than the folding section and also less than the wall thickness at the end where the connecting portion joins with it. This makes the thin-walled section more flexible, allowing the bending portion to fold from the thin-walled section when rotating relative to the connecting portion. This makes the squeegee body easier to bend and adjust its angle, thus better conforming to the contours of the floor or surface to be cleaned. Simultaneously, this flexibility helps ensure the squeegee effectively removes dust, dirt, and debris, improving cleaning results.

[0031] In one possible implementation, the connecting portion includes a blocking portion; wherein,

[0032] The blocking part is located on the side of the thin-walled section opposite to the roller brush, and is spaced apart from the thin-walled section;

[0033] The blocking part extends vertically toward the surface to be cleaned, and the thickness of the blocking part in the vertical direction is greater than the wall thickness of the thin-walled section, so as to ensure that the scraper assembly bends at the thin-walled section.

[0034] By setting a blocking part on the connecting part, the thin-walled section can be supported when it rotates and bends, thereby preventing the bending angle of the bending part from being too large and affecting the cleaning effect.

[0035] In one possible implementation, the side of the folded section facing away from the roller brush is provided with reinforcing ribs.

[0036] By incorporating reinforcing ribs into the folding section, the wall thickness can be increased, thereby enhancing its overall strength and rigidity. This prevents deformation or breakage during use, extending its service life. The reinforcing ribs also help maintain the shape of the folding section, ensuring it retains an effective working angle during cleaning, thus improving cleaning efficiency. Furthermore, the reinforcing ribs help distribute pressure evenly during cleaning, preventing uneven cleaning caused by localized bending or excessive localized stress that could lead to wear or damage. This contributes to extending the folding section's service life and maintaining its cleaning performance.

[0037] In one possible implementation, the bent portion includes an initial state and a bent state; wherein,

[0038] When the bent portion is in the initial state, the bent portion does not rotate relative to the connecting portion, the bent portion is parallel to the vertical direction, or the end of the bent portion near the surface to be cleaned is inclined at a first angle toward the direction of the roller brush, the first angle being less than or equal to 30°.

[0039] When the bent portion is in the bent state, the bent portion rotates and bends at a preset angle relative to the connecting portion in a direction closer to the roller brush or in a direction away from the roller brush.

[0040] By setting the bending section parallel to the vertical direction in its initial state, or by tilting the end of the bending section near the surface to be cleaned towards the roller brush at a first angle less than or equal to 30°, the bending section can easily rotate and bend at a preset angle towards or away from the roller brush. If the first angle is set greater than 30°, it becomes more difficult for the bending section to rotate and bend away from the roller brush, affecting the cleaning effect.

[0041] In one possible implementation, the length of the bend is less than or equal to 20 mm in the extending direction of the bend.

[0042] This design allows for a shorter bend, making it more flexible and efficient in collecting and cleaning dust, dirt, and debris. Since the side of the water tank assembly facing the surface to be cleaned needs space for the bend, an excessively long bend would waste space and reduce the water tank's capacity. Furthermore, if the bend is too long, the time required for bending and resetting increases in tandem with the travel distance of the corresponding roller brush, increasing the risk of water and dirt accumulation during the scraper assembly's resetting process. Therefore, setting the bend length to be less than or equal to 20 mm improves cleaning effectiveness.

[0043] In one possible implementation, the scraper assembly further includes a scraper support; wherein,

[0044] One end of the scraper bracket is fixedly connected to the connecting part of the scraper body, and the other end is fixedly connected to the water tank assembly.

[0045] By incorporating a scraper bracket, the scraper body can be easily connected to the water tank assembly, improving connection stability and reducing scraper assembly vibration, thereby minimizing noise. Furthermore, a stable connection between the scraper assembly and the water tank assembly prevents the scraper body from detaching during use, thus extending its service life.

[0046] In one possible implementation, the water tank assembly includes a clean water tank and a wastewater tank; wherein,

[0047] The wastewater tank is located between the clean water tank and the roller brush;

[0048] The opening is located at the end of the sewage tank facing the roller brush, and the opening is connected to the sewage tank. The clean water tank is connected to the roller brush. The clean water tank is used to provide clean water to the roller brush, and the sewage tank is used to contain garbage entering through the opening.

[0049] By configuring the water tank assembly to include a clean water tank and a wastewater tank, with the wastewater tank connected to an opening, debris scraped off the opening can enter the wastewater tank for easy collection and centralized processing. By including a clean water tank connected to the roller brush, the roller brush can be moistened with clean water, thus improving its cleaning efficiency during cleaning operations.

[0050] By placing the wastewater tank between the clean water tank and the roller brush, with the opening located at the end of the wastewater tank facing the roller brush, the wastewater tank can be brought closer to the roller brush, reducing the distance that garbage needs to travel to enter the wastewater tank and shortening the garbage's travel distance. This makes garbage recycling more thorough and efficient, while also making efficient use of the internal space of the floor brush assembly.

[0051] In one possible implementation, a waste disposal channel is also included; wherein,

[0052] The waste passage is connected to both the receiving cavity and the opening.

[0053] By setting up a waste channel, garbage and other debris are driven by a roller brush to fall into the wastewater tank along the waste channel.

[0054] In one possible implementation, the waste channel is formed between the side of the scraper body facing the roller brush, the side of the waste tank facing the roller brush, and the side of the roller brush facing the waste tank.

[0055] By placing the dirt channel between the side of the scraper body facing the roller brush, the side of the wastewater tank facing the roller brush, and the side of the roller brush facing the wastewater tank, the dirt can be brushed up by the roller brush, and the dirt can be scraped and confined in the dirt channel by the scraper assembly so that it can enter the wastewater tank from the opening, thereby improving cleaning efficiency.

[0056] In one possible implementation, the scraper assembly extends from one end toward the surface to be cleaned. roller brush The distance between the center sections of the roller brush is the second distance. The center section of the roller brush passes through the straight line where the center of rotation of the roller brush is located and is perpendicular to the surface to be cleaned. The second distance is greater than or equal to 10 mm and less than or equal to 30 mm.

[0057] By setting the second distance to less than or equal to 30 mm, the distance between the bend in the scraper assembly and the roller brush can be reduced, preventing excessive accumulation of dirt between the scraper body and the roller brush. This prevents dirt from being swept up by the roller brush and entering the wastewater tank through the opening, and may also create wastewater streaks. By setting the second distance to greater than or equal to 10 mm, the distance between the scraper body and the roller brush can be prevented from being too small, which would result in insufficient rotation and containment space after the dirt is swept up by the roller brush, thus reducing the dirt-cleaning ability.

[0058] In one possible implementation, the water tank assembly is detachably connected to the housing assembly.

[0059] By detachably connecting the water tank assembly and the housing assembly, it is easy to add water to the clean water tank in the water tank assembly and to clean the waste water tank.

[0060] In one possible implementation, a detection device and a control device are also included; wherein,

[0061] The detection device is electrically connected to the control device. The detection device is used to detect the first distance between the scraper assembly and the surface to be cleaned. The control device is used to control the water supply of the water tank assembly to the roller brush.

[0062] By incorporating detection and control devices, the water supply M can be adjusted in real time based on the initial distance H, ensuring that the roller brush receives adequate moisture under different cleaning conditions, thus improving cleaning effectiveness. Water is supplied according to actual needs, avoiding excessive or insufficient water supply and conserving water resources. The system automatically adjusts the water supply M based on detection results, eliminating the need for manual adjustment by the user, improving ease of operation and reducing the user's workload.

[0063] A second aspect of this application provides a cleaning device, including a device body and a floor brush assembly as described in any of the first aspects above; wherein...

[0064] The floor brush assembly is located at one end of the main body of the device and is rotatably connected to the main body of the device.

[0065] The cleaning device in this embodiment, by incorporating the aforementioned floor brush assembly, enables it to clean surfaces both dry and wet. Furthermore, the clean water tank wets the roller brush, enhancing its cleaning ability. Both the clean water tank and the wastewater tank are mounted on the floor brush assembly, making the device lightweight and convenient for users, reducing their workload.

[0066] In one possible implementation, the cleaning device is a vacuum cleaner.

[0067] By setting the cleaning device as a vacuum cleaner, it can be equipped with the ability to clean surfaces with water stains, and it can also perform the functions of a regular vacuum cleaner, thereby meeting the user's daily cleaning needs and improving the user experience.

[0088] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0089] The following describes in detail the floor brush assembly and cleaning equipment provided in the embodiments of this application with reference to the accompanying drawings.

[0090] Figure 1 This is a schematic diagram of the structure of a floor brush assembly provided in an embodiment of this application. Figure 2 This is a cross-sectional structural diagram of a floor brush assembly provided in an embodiment of this application.

[0091] It should be noted that, for ease of description, in the embodiments of this application, the thickness direction of the housing component of the floor brush assembly is taken as the z-direction, the axial direction of the roller brush is taken as the y-direction, and the direction from the roller brush to the water tank assembly is taken as the x-direction.

[0092] This application provides a floor brush assembly 100 for a vacuum cleaner, such as... Figure 1 As shown, the floor brush assembly 100 may include a housing assembly 10, a roller brush 20, and a water tank assembly 30.

[0093] like Figure 2As shown, the housing assembly 10 may include a receiving cavity 12. A roller brush 20 is disposed within the receiving cavity 12 and rotatably connected to the housing assembly 10. The roller brush 20 is used to perform cleaning operations on the surface 200 to be cleaned. A water tank assembly 30 is spaced apart from the roller brush 20 in the radial direction of the roller brush 20. One end of the water tank assembly 30 facing the roller brush 20 is in partial communication with the receiving cavity 12. The water tank assembly 30 is used at least to supply clean water to the roller brush 20.

[0094] The water tank assembly 30 includes a clean water tank 32 and a wastewater tank 31. An opening 314 is connected to the wastewater tank 31, and the clean water tank 32 is connected to the roller brush 20. The clean water tank 32 is used to provide clean water to the roller brush 20, and the wastewater tank 31 is used to contain garbage entering through the opening 314.

[0095] The floor brush assembly 100 provided in this application embodiment includes a housing assembly 10 with a receiving cavity 12 for mounting a roller brush 20. The roller brush 20 is configured to perform cleaning operations. A water tank assembly 30 is provided with an opening 314 communicating with the receiving cavity 12, allowing debris and other contaminants to enter the water tank assembly 30 through the opening 314.

[0096] By configuring the water tank assembly 30 to include a clean water tank 32 and a wastewater tank 31, with the wastewater tank 31 connected to the opening 314, garbage can enter the wastewater tank 31 for easy collection and centralized treatment. By including the clean water tank 32 and connecting it to the roller brush 20, the roller brush 20 can be wetted through the clean water tank 32, thus improving its cleaning ability during cleaning operations.

[0097] It should be noted that in the embodiments of this application, "orientation" refers to orientation in a broad sense and is not limited to a front-facing arrangement, and "away from" refers to away from in a broad sense and is not limited to a back-to-back parallel arrangement.

[0098] For example, such as Figure 2 As shown, the housing assembly 10 may include a front cover plate 11, which is located on top of the roller brush 20. Along the axial direction (y-direction) of the roller brush 20, the housing assembly 10 has fixing brackets 13 at both ends. One end of each fixing bracket 13 is connected to the housing assembly 10, and the other end is rotatably connected to the roller brush 20, forming a receiving cavity 12 between the side of the front cover plate 11 facing the roller brush 20 and the two fixing brackets 13. The front cover plate 11 can be used to shield part of the roller brush 20, thus preventing dust from flying from the roller brush 20 during operation. For example, the front cover plate 11 can be a transparent arc-shaped plate structure.

[0099] See also Figure 2As shown, in the direction from the roller brush 20 to the water tank assembly 30, that is, in the x-direction, the wastewater tank 31 can be located between the clean water tank 32 and the roller brush 20. The opening 314 can be located at the end of the wastewater tank 31 facing the roller brush 20.

[0100] This configuration allows the wastewater tank 31 to be positioned close to the roller brush 20, reducing the distance that waste needs to travel to enter the wastewater tank 31 and shortening the waste's travel distance, resulting in more thorough and efficient waste collection. It also makes efficient use of the internal space of the floor brush assembly. Furthermore, this allows the clean water tank 32 to be located at the end of the housing assembly 10 away from the roller brush 20, helping to evenly distribute the weight of the floor brush assembly 100, increasing the stability of the equipment and improving operational comfort. This also helps reduce user fatigue during use.

[0101] For example, a portion of the housing assembly 10 is located at the top of the wastewater tank 31 and is spaced apart from the top of the wastewater tank 31. This forms an opening 314 between the end of the wastewater tank 31 facing the roller brush 20 and the housing assembly 10, allowing dirt and the like to enter the wastewater tank 31 through the opening 314.

[0102] It should be noted that the portion of the housing assembly 10 located at the top of the sewage tank 31 is configured as the top wall of the sewage tank 31.

[0103] like Figure 3 As shown, the floor brush assembly 100 may further include a scraper assembly 40. The scraper assembly 40 is disposed at the end of the water tank assembly 30 facing the roller brush 20, and the minimum distance between the scraper assembly 40 and the surface 200 to be cleaned is a first distance H. The ratio of the water supply rate (g / min) of the water tank assembly 30 to the roller brush 20 to the first distance H (mm) is between 3 and 22.

[0104] It should be noted that, because the surface of the roller brush 20 is elastic, the first distance H refers to the distance between the bottom end of the scraper assembly 40 and the surface 200 to be cleaned when the ground brush assembly 100 is located on the surface 200 to be cleaned and the cleaning operation is performed on the surface 200 to be cleaned. It is not the distance between the bottom end of the scraper assembly 40 and the side of the roller brush 20 facing the surface 200 to be cleaned.

[0105] By configuring the scraper assembly 40 and positioning it at the end of the water tank assembly 30 facing the roller brush 20, dust, dirt, and debris are brushed up from the ground as the roller brush 20 rotates in front. The scraper assembly 40 guides the dirt brushed up by the roller brush 20 to the opening 314, ensuring efficient collection and optimizing cleaning results. The scraper assembly 40 also prevents dust and debris brushed up by the roller brush 20 from falling back onto the ground during cleaning, thus avoiding secondary pollution and improving cleaning efficiency.

[0106] A first distance H exists between the scraper assembly 40 and the surface 200 to be cleaned. This prevents excessive friction between the scraper assembly 40 and the surface 200, thus avoiding damage to the floor, especially for wooden floors or other easily damaged surfaces. It also reduces the resistance between the scraper assembly 40 and the floor, making the floor brush assembly operate more smoothly and reducing user fatigue.

[0107] Furthermore, in existing wet floor cleaning technologies, the roller brush leaves a layer or streaks of water on the surface being cleaned during operation. Under current technology, increasing the water supply to the roller brush can enhance its cleaning ability. However, this increased water supply inevitably leads to a greater amount of water left on the surface. If this residual water is not treated, it negatively impacts the cleaning experience and may even pose safety hazards. Current technologies employ two solutions: First, creating low pressure within the equipment to introduce suction and draw in a mixture of solid, liquid, and gaseous waste for recycling. Second, setting the scraper blade to be in contact with or press against the floor, forcefully scraping the residual water to the roller brush, where its rotation drives the water's recovery. Solution one significantly increases the size and weight of the cleaning equipment. Solution two increases the risk of scraper blade wear and floor damage, and the residual water is disturbed by the scraper blade, accumulating noticeable water streaks on the sides of the cleaning equipment, resulting in unsatisfactory cleaning performance.

[0108] This application provides a solution to improve or eliminate watermarks. On one hand, the water supply is appropriately reduced. On the other hand, the scraper assembly 40 is positioned at a first distance H from the surface to be cleaned 200. Appropriately reducing the water supply allows the residual water on the surface to be cleaned 200 to be controlled within an acceptable range for the user. Although some cleaning power is sacrificed, the weight of the cleaning equipment is significantly reduced, the handling performance is optimized, and the difficulty of handling residual water on the surface to be cleaned 200 is greatly reduced. At this time, the dirt and residual water on the surface to be cleaned 200 are mainly wiped, rolled up, and collected by the roller brush 20, ensuring a suitable cleaning effect. Therefore, during the use of the cleaning equipment 1000, the scraper assembly 40 does not need to collect residual water on the surface to be cleaned 200 in most cases. Furthermore, the scraper assembly 40 can be raised to a certain gap, without disturbing the residual water layer on the surface to be cleaned 200, preventing the residual liquid on the surface to be cleaned 200 from accumulating and forming several watermarks. The smaller initial distance H ensures that the scraper assembly 40 remains within close proximity to the surface 200 to be cleaned, effectively removing non-liquid contaminants. This helps improve cleaning efficiency, achieving both the avoidance of watermarks and the removal of solid contaminants, resulting in a cleaner surface 200.

[0109] As mentioned above, the design of the water supply volume and the first distance H is related. If the water supply volume is too large and the first distance H is too small, the problem of residual water on the surface 200 to be cleaned still cannot be solved. If the water supply volume is reduced, the first distance H does not need to be large because the residual water on the surface 200 to be cleaned is reduced. Otherwise, not only will the roller brush 20 be unable to clean the dirt on the surface to be cleaned, but the scraper assembly 40 will also have a reduced ability to remove solid dirt from the surface 200 to be cleaned. Therefore, the ratio of water supply volume M to the first distance H is controlled within a certain range.

[0110] Therefore, the improvement of this application based on the prior art lies in controlling the ratio of water supply M (g / min) to the first distance H (mm) to be between 3 and 22. For example, the ratio of water supply M (g / min) to the first distance H (mm) can be 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, etc. In the embodiments of this application, the ratio of water supply M (g / min) to the first distance H (mm) is not further limited.

[0111] In this embodiment, the water supply M fluctuates between 8.5 and 11 g / min, maintaining a certain cleaning effect of the roller brush 20 without leaving excessive water on the surface 200 to be cleaned. The first distance H is controlled between 0.5 and 3 mm to prevent watermarks. Therefore, the maximum ratio of water supply to the first distance H is 22. If this ratio exceeds 22, either the water supply increases or the first distance H decreases, both of which will lead to watermarks remaining on the surface 200 to be cleaned. Similarly, the minimum ratio of water supply to the first distance H is 3. If this ratio is less than 3, either the water supply is too small to achieve the expected cleaning effect, or the first distance H is too large to collect non-liquid contaminants on the surface 200 to be cleaned. In summary, the best cleaning effect is achieved when the ratio of water supply (g / min) to the first distance H (mm) is between 3 and 22.

[0112] In this embodiment of the application, the first distance H is greater than or equal to 0.5 and less than or equal to 3 millimeters.

[0113] For example, the first distance H can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm. In this embodiment, the first distance H is not further limited.

[0114] In one possible implementation, the first distance H is greater than 0.5 mm and less than or equal to 1 mm. This is also the optimal range for the first distance H.

[0115] This configuration further reduces the distance between the scraper assembly 40 and the surface 200 to be cleaned, thereby enhancing the scraper assembly 40's ability to clean smaller diameter non-liquid contaminants on the surface 200 and more effectively removing dust, dirt, and debris. This helps improve cleaning efficiency and makes the floor cleaner. When the first distance H decreases, the water supply from the clean water tank 32 to the roller brush 20 also decreases synchronously to meet the maximum limit of the ratio of water supply to the first distance H. Of course, too little water supply will also affect the wet cleaning ability of the roller brush 20, and it still needs to meet the minimum limit of the ratio of water supply to the first distance H.

[0116] For example, the clean water tank 32 and the roller brush 20 can be connected via a water supply pipe (not shown in the figure). For instance, one end of the water supply pipe can be connected to the clean water tank 32, and the other end can be connected to the roller brush 20. Furthermore, the water supply pipe can be connected to a water pump, so that clean water from the clean water tank 32 can be pumped into the roller brush 20 through the water pump and the water supply pipe, thereby wetting the roller brush 20 and improving the cleaning effect.

[0117] It should be noted that, compared to a floor scrubber, the water tank 32 in this embodiment has a smaller capacity. During use, the water supply to the roller brush 20 is also smaller to maintain better battery life. Although its cleaning ability for stubborn dirt is not as good as a floor scrubber, it is more portable and suitable for simple wet cleaning scenarios.

[0118] In one possible implementation, such as Figure 4 As shown, the floor brush assembly may include a detection device 51 and a control device 52, with the detection device 51 and control device 52 electrically connected. The detection device is used to detect a first distance H between the scraper assembly 40 and the surface 200 to be cleaned. The control device is used to control the water supply M (g / min) from the water tank assembly 30 to the roller brush 20.

[0119] For example, the control device 52 can be connected to the water supply pipeline of the clean water tank 32. For instance, the control device 52 can be located between the clean water tank 32 and the water supply pipeline, or at the end of the water supply pipeline away from the clean water tank 32, or in the middle of the water supply pipeline. In this embodiment, the location of the control device 52 is not further limited. The control device 52 controls the water supply (g / min) from the water tank assembly 30 to the roller brush 20 by controlling the water flow rate in the water supply pipeline.

[0120] Optionally, the detection device 51 can be a distance sensor. The control device 52 can be a solenoid valve, flow controller, pump control system, electronic control system, pressure regulator, etc. In this embodiment, the specific structure of the detection device 51 and the control device 52 is not further limited.

[0121] By setting up the detection device 51 and the control device 52, the water supply M can be adjusted in real time according to the first distance H, ensuring that the roller brush 20 receives an appropriate amount of water under different conditions on the surface 200 to be cleaned, thereby improving the cleaning effect. Water is supplied according to actual needs, avoiding excessive or insufficient water supply and conserving water resources. The system automatically adjusts the water supply M based on the detection results without requiring manual adjustment by the user, improving operational convenience and reducing the user's workload.

[0122] In one possible implementation, see [link to previous section] Figure 2 and Figure 3 As shown, the floor brush assembly 100 may further include a waste channel. This waste channel communicates with both the receiving cavity 12 and the opening 314. For example, a waste channel is formed between the side of the scraper body 41 facing the roller brush 20, the side of the waste tank 31 facing the roller brush 20, and the side of the roller brush 20 facing the waste tank 31. The dashed lines with arrows in the figure indicate the flow path of the waste in the waste channel.

[0123] By setting up a waste channel, garbage and other debris can enter the wastewater tank 31 along the waste channel. By positioning the waste channel between the side of the scraper body 41 facing the roller brush 20, the side of the wastewater tank 31 facing the roller brush 20, and the side of the roller brush 20 facing the wastewater tank 31, dirt can be brushed up by the roller brush 20, and scraped and confined within the waste channel by the scraper assembly 40, so that it can enter the wastewater tank 31 through the opening 314, thereby improving cleaning efficiency.

[0124] For example, the water tank assembly 30 can be detachably connected to the housing assembly 10. This allows for easy addition of water to the clean water tank 32 within the water tank assembly 30, and also facilitates the cleaning of the wastewater tank 31.

[0125] In the embodiments of this application, the water tank assembly 30 and the shell assembly 10 can be detachably connected by a snap-fit ​​connection or by a plug-in connection. The detachable connection method between the water tank assembly 30 and the shell assembly 10 is not further limited.

[0126] In some embodiments, the clean water tank 32 and the wastewater tank 31 of the water tank assembly 30 can be an integral structure or a separate structure. For example, the wastewater tank 31 and the clean water tank 32 can be detachably connected. During assembly, the clean water tank 32 and the wastewater tank 31 can be assembled first, and then the water tank assembly 30 can be assembled with the shell assembly 10. In this embodiment, the structural relationship between the clean water tank 32 and the wastewater tank 31 is not further limited.

[0127] In this embodiment, the capacity of the clean water tank 32 is not further limited. Furthermore, in this embodiment, the clean water tank 32 is mounted on the floor brush assembly 100, whereas it is mounted on the handle of the floor scrubber. This reduces the burden on the user during use, helping to decrease user fatigue and improve the user experience.

[0128] For example, the outer side of the roller brush 20 may be provided with a bristle layer, which can be used to clean and wipe the surface 200 to be cleaned, thereby improving the cleaning effect of the floor brush assembly 100. Of course, in other embodiments, the outer side of the roller brush 20 may not be provided with a bristle layer. In this embodiment, the specific structure of the roller brush 20 is not further limited.

[0129] The scraper assembly 40 will now be described in detail with reference to the accompanying drawings.

[0130] In one possible implementation, such as Figure 5 As shown, the scraper assembly 40 may include a scraper body 41. The scraper body 41 includes a connecting portion 411 and a bending portion 412. The connecting portion 411 is used to connect to the water tank assembly 30, and the bending portion 412 extends toward the surface 200 to be cleaned. The bending portion 412 is rotatable relative to the connecting portion 411 about a direction parallel to the central axis of the roller brush 20.

[0131] The scraper assembly 40 may also include a scraper bracket 42, wherein one end of the scraper bracket 42 is fixedly connected to the connecting part 411 of the scraper body 41, and the other end is fixedly connected to the water tank assembly 30.

[0132] By providing a scraper body 41, cleaning operations are performed. The scraper body 41 includes a connecting portion 411 and a bending portion 412, allowing it to be fixedly connected to the water tank assembly 30 via the connecting portion 411. The bending portion 412, which can rotate relative to the connecting portion 411, allows the scraper body 41 to better conform to the contours of the surface to be cleaned, ensuring a more comprehensive and thorough cleaning. It also helps to scrape away dust, dirt, and debris from the floor, improving cleaning efficiency.

[0133] The design of the bend 412 allows the scraper body 41 to adapt to various types of surfaces, including uneven floors, carpets, and tile grout. It also reduces resistance between the scraper body and the surface to be cleaned 200, making it smoother during use, reducing the difficulty and fatigue of user operation, and reducing excessive friction and pressure between the scraper body and the surface to be cleaned 200, extending its service life, reducing wear and damage, thereby providing a consistent cleaning effect, and also reducing noise.

[0134] The flexible bend 412 reduces friction and pressure on the floor, preventing scratches or damage, especially on wood floors or other vulnerable surfaces. The bend 412 design increases the flexibility of the squeegee body 41, enabling it to perform effectively in complex cleaning tasks.

[0135] By setting up the scraper bracket 42, the scraper body 41 can be easily connected to the water tank assembly 30, improving connection stability and reducing vibration of the scraper assembly 40, thereby reducing noise. In addition, the stable connection between the scraper assembly 40 and the water tank assembly 30 can also prevent the scraper body 41 from falling off during use, thus extending its service life.

[0136] For example, the scraper body 41 can be an integral structure, which can be obtained by injection molding. The scraper bracket 42 and the connecting part 411 can be fixedly connected by means of bonding, snap-fitting, injection molding, etc. In this embodiment of the application, the connection relationship between the scraper bracket 42 and the connecting part 411 is not further limited.

[0137] In the embodiments of this application, see also Figure 2 As shown, the scraper bracket 42 can be fixedly connected to the body of the sewage tank 31. The scraper bracket 42 includes a first assembly part 421 and a second assembly part 422. The first assembly part 421 is used to connect with the connecting part 411 of the scraper body 41, and the second assembly part 422 is used to fixally connect to the body of the sewage tank 31.

[0138] For example, the sewage tank 31 has a mating part 33 on its body that mates with the second assembly part 422. In the direction from the roller brush 20 to the tank assembly 30 (x-direction), the second assembly part 422 engages with the mating part 33. In the axial direction of the roller brush 20, the second assembly part 422 can be inserted into the mating part 33. This allows the scraper assembly 40 to be removed from the tank assembly 30 for easy replacement.

[0139] For example, the second assembly part 422 includes a first stop arm 4221 and a second stop arm 4222, wherein the first stop arm 4221 and the second stop arm 4222 extend in a direction away from each other, and when the second assembly part 422 is assembled with the mating part 33, the first stop arm 4221 and the second stop arm 4222 abut against the mating part 33 respectively.

[0140] Of course, in other embodiments, the second assembly part 422 may also be other structures, such as only including the first stop arm 4221, or only including the second stop arm 4222. In the embodiments of this application, the specific structure of the second assembly part 422 and the mating part 33 is not further limited, as long as a fixed connection and a detachable connection can be achieved.

[0141] In one possible implementation, see Figure 6 As shown, the bending portion 412 may include a thin-walled section 4121 and a folded section 4122. The thin-walled section 4121 is located between the folded section 4122 and the connecting portion 411, and serves to fix the folded section 4122 and the connecting portion 411 together. The wall thickness of the thin-walled section 4121 is less than the wall thickness of the folded section 4122, and also less than the wall thickness of the end of the connecting portion 411 connected to the thin-walled section 4121.

[0142] This configuration allows for greater design flexibility of the scraper body 41 by configuring the bending portion 412 to include a thin-walled section 4121 and a folding section 4122, and by designing the bending portion 412 of the scraper body 41 to be a multi-segment structure with different wall thicknesses. The wall thickness of the thin-walled section 4121 is less than the wall thickness of the folding section 4122, and also less than the wall thickness of the end of the connecting portion 411 connected to the thin-walled section 4121. This makes the position of the thin-walled section 4121 more flexible, allowing the bending portion 412 to bend from the thin-walled section 4121 when rotating relative to the connecting portion 411. This makes the scraper body 41 easier to bend and adjust its angle, thus better conforming to the contours of the floor or the surface to be cleaned. Simultaneously, this flexibility helps ensure that the scraper can effectively remove dust, dirt, and debris, improving cleaning performance.

[0143] For example, a groove structure 43 can be formed at the location where the bending portion 412 and the connecting portion 411 are connected to form a thin-walled section 4121. The groove structure 43 is recessed in the vertical direction away from the surface to be cleaned 200, which can reduce the wall thickness at the connection between the connecting portion 411 and the bending portion 412, thereby facilitating the formation of the thin-walled section 4121.

[0144] A protrusion 44 is provided on the side of the bent portion 412 facing the roller brush 20, thereby forming a thin-walled segment 4121 at the connection between the bent portion 412 and the connecting portion 411. Furthermore, the wall thickness of the thin-walled segment 4121 is less than the wall thickness at the location of the protrusion 44 and also less than the wall thickness of the connecting portion 411, so the rigidity at the location of the thin-walled segment 4121 is minimal, making it easy to bend. In this embodiment, the bent portion 412 located at the end of the thin-walled segment 4121 facing the surface to be cleaned 200 is configured as a folded segment 4122.

[0145] It should be noted that, in this embodiment, the length of the thin-walled segment 4121 in the extending direction of the scraper body 41 is not further limited, and can be set according to specific circumstances. For example, it can be 2 mm, 3 mm, 4 mm, etc. Furthermore, the thickness of the thin-walled segment 4121 is not further limited.

[0146] In one possible implementation, the connecting portion 411 may include a blocking portion 4111. The blocking portion 4111 is located on the side of the thin-walled section 4121 facing away from the roller brush 20 and is spaced apart from the thin-walled section 4121. The blocking portion 4111 extends vertically toward the surface 200 to be cleaned, and the thickness of the blocking portion 4111 in the vertical direction is greater than the wall thickness of the thin-walled section 4121, to ensure that the scraper assembly bends at the thin-walled section.

[0147] For example, the blocking part 4111 can be an arc-shaped protrusion, a square protrusion, etc. provided at the connecting part 411. In this embodiment of the application, the shape of the blocking part 4111 is not further limited.

[0148] By providing a blocking part 4111 on the connecting part 411, the thin-walled section 4121 can be supported when it is rotated and bent, thereby preventing the bending angle of the bending part 412 from being too large and affecting the cleaning effect.

[0149] In one possible implementation, see [link to previous section] Figure 6 As shown, the folded section 4122 has a reinforcing rib 45 on the side facing away from the roller brush 20. Exemplarily, the reinforcing rib 45 is arranged longitudinally, and multiple reinforcing ribs 45 are spaced apart along the axial direction of the roller brush 20. Of course, the number of reinforcing ribs 45 can also be a single reinforcing rib 45 extending along the axial direction of the roller brush 20. In this embodiment, the number and shape of the reinforcing ribs 45 are not further limited.

[0150] By incorporating reinforcing ribs 45 into the folding section 4122, the wall thickness of the folding section 4122 can be increased, thereby increasing its overall strength and rigidity. This prevents deformation or breakage during use, thus extending its service life. The reinforcing ribs 45 help maintain the shape of the folding section 4122, ensuring it maintains an effective working angle during cleaning, thus improving cleaning efficiency. The reinforcing ribs 45 also help distribute pressure evenly during cleaning, preventing uneven cleaning caused by localized bending. This contributes to extending the service life of the folding section 4122 and maintaining its cleaning performance.

[0151] In one possible implementation, the bent portion 412 includes an initial state and a bent state. Wherein, as... Figure 6 As shown, when the bending portion 412 is in the initial state, the bending portion 412 does not rotate relative to the connecting portion 411, the bending portion 412 is parallel to the vertical direction, or the end of the bending portion 412 near the surface to be cleaned 200 is inclined at a first angle α towards the direction of the roller brush 20, and the first angle α is less than or equal to 30°.

[0152] like Figure 7As shown, when the bent portion 412 is in a bent state, the bent portion 412 rotates and bends by a preset angle relative to the connecting portion 411 in a direction away from the roller brush 20. Of course, in some embodiments, the bent portion 412 may also rotate and bend by a preset angle relative to the connecting portion 411 in a direction closer to the roller brush 20.

[0153] It should be noted that the preset angle is related to the structure, shape, and material of the scraper assembly 40, as well as the size and nature of the dirt on the ground, and therefore can be set according to specific needs. In this embodiment, the preset angle is not further limited.

[0154] By setting the bending portion 412 parallel to the vertical direction in its initial state, or by tilting the end of the bending portion 412 near the surface to be cleaned 200 towards the roller brush 20 at a first angle less than or equal to 30°, the bending portion 412 can be easily rotated and bent at a preset angle towards or away from the roller brush 20. If the first angle is set greater than 30°, it becomes more difficult for the bending portion 412 to rotate and bend away from the roller brush 20, affecting the cleaning effect.

[0155] In one possible implementation, the length of the bend 412 is less than or equal to 20 mm in the extending direction of the bend 412. For example, the length of the bend 412 can be 20 mm, 19 mm, 18 mm, 17 mm, 16 mm, 15 mm, 14 mm, 13 mm, etc. In this embodiment, the length of the bend 412 is not further limited.

[0156] This design allows for a shorter bending section 412, making it more flexible and efficient in collecting and cleaning dust, dirt, and debris. Since the side of the water tank assembly 30 facing the surface 200 to be cleaned needs space for the bending section 412 to bend, if the bending section 412 is too long, it will waste space and reduce the capacity of the water tank assembly 30. Furthermore, if the bending section 412 is too long, the time required for bending and resetting will increase in tandem with the travel distance of the corresponding roller brush 20, increasing the risk of water and dirt accumulation during the resetting process of the scraper assembly 40. Therefore, setting the length of the bending section 412 to be less than or equal to 20 mm improves the cleaning effect.

[0157] In one possible implementation, see [link to previous section] Figure 3 As shown, the distance from the end of the scraper assembly 40 facing the surface 200 to the center section S of the roller brush 20 is the second distance h. The center section S of the roller brush 20 passes through the straight line containing the rotation center of the roller brush 20 and is perpendicular to the surface 200 to be cleaned. The second distance h is greater than or equal to 10 mm and less than or equal to 30 mm.

[0158] For example, the second distance h can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc. In this embodiment of the application, the specific value of the second distance h is not further limited.

[0159] By setting the second distance h to less than or equal to 30 mm, the distance between the bend 412 of the scraper assembly 40 and the roller brush 20 can be smaller, preventing excessive accumulation of dirt between the scraper body 41 and the roller brush 20, which would prevent the dirt from being brushed up by the roller brush 20 and entering the wastewater tank 31 through the opening 314, and could also cause wastewater stains. By setting the second distance to greater than or equal to 10 mm, the distance between the scraper body 41 and the roller brush 20 can be prevented from being too small, which would result in insufficient rotation and accommodation space after the dirt is rolled up by the roller brush 20, thus reducing the ability to clean dirt.

[0160] This application embodiment also provides a cleaning device 1000, such as... Figure 8 As shown, the device includes a main body 300 and a floor brush assembly 100 as described in any of the above embodiments. The floor brush assembly 100 is disposed at one end of the main body 300 and is rotatably connected to the main body 300.

[0161] The cleaning device 1000 in this embodiment, by incorporating the floor brush assembly 100 described in the first aspect, enables the cleaning device 1000 to clean both dry and wet surfaces 200. Furthermore, the clean water tank 32 wets the roller brush 20, thus enhancing its cleaning ability. Additionally, both the clean water tank 32 and the wastewater tank 31 are mounted on the floor brush assembly 100, making the device lightweight and convenient for users, reducing their operational burden.

[0162] In one possible implementation, the cleaning device 1000 is a vacuum cleaner.

[0163] By setting the cleaning device 1000 as a vacuum cleaner, the vacuum cleaner can be equipped with the ability to clean the surface 200 with water stains, and it can also have the functions of a regular vacuum cleaner, thereby meeting the user's daily cleaning needs and improving the user experience.
