Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a cleaning system. BACKGROUND

[0002] The cleaning function of cleaning equipment such as scrubber and mop-integrated machine is increasingly advanced, and heating function is generally added, for example, the functions of hot air drying and hot water cleaning of the brush in the self-cleaning stage, which aims to better remove bacteria, dry and remove oil stains, and is widely praised by users. These heating functions currently mainly rely on temperature sensors to monitor temperature, and such temperature sensors interact with controllers to realize temperature control, but users cannot know the heating situation. Even if the related heating function is damaged or aged, the use effect is reduced, and it cannot be known in time. The heating condition of the cleaning equipment for the brush is poor in user interaction, and the convenient use experience needs to be further improved. SUMMARY

[0003] In view of the above problems, the present application provides a cleaning system.

[0004] In order to achieve the above purpose, the present application provides the following technical scheme:

[0005] The present application provides a cleaning system, which comprises a cleaning device and a base matched with the cleaning device;

[0006] The cleaning device comprises a floor brush, the floor brush comprises a floor brush body and a cleaning assembly arranged on one side of the floor brush body, and a dirt suction port is arranged on the floor brush body to suck dirt on a surface to be cleaned;

[0007] The cleaning system is configured to have a drying mode, in the drying mode, the cleaning device is configured to be arranged on the base, and the base is configured to dry the cleaning assembly;

[0008] In the drying mode, at least part of the area of the cleaning assembly away from the dirt suction port can change color.

[0009] In the drying mode, the first heating assembly in the drying assembly works, the airflow blown by the fan is heated by the first heating assembly to form hot airflow, and the hot airflow is blown to the cleaning assembly along the drying air duct. The temperature of the cleaning assembly is increased by the hot airflow, and the color changes. The color change can be observed, for example, the color change of the cleaning assembly can be observed by the user through the window, thereby reminding the user that the current stage is hot drying.

[0010] Users can see the cleaning components change color as the temperature rises, allowing them to visually perceive whether they are using the drying mode, hot water self-cleaning mode (mentioned below), or hot water cleaning function (mentioned below), thus improving the user experience. Moreover, this interaction method is effective and cost-efficient.

[0011] Color changes can also be used to warn of damage to the cleaning system. For example, if the cleaning component does not change color in drying mode, it may indicate that the first heating component is damaged or the heating effect is poor, preventing the cleaning component from reaching the color-changing temperature.

[0012] Meanwhile, the color-changing position can be set to at least a portion of the area away from the suction port, that is, the opposite side after suction. The cleaning component can calculate or control its stopping position during rotation. By controlling the setting of a color-changing part on the opposite side of the suction port, users can more easily observe the changes of the cleaning component.

[0013] Furthermore, the cleaning component can be set with color-changing areas at equal intervals around the axis, ensuring that the color change can be seen on the opposite side of the suction port after the cleaning component stops.

[0014] On the other hand, not all cleaning components are set to be color-changing. That is, the cleaning components may include parts that do not change color and parts that can change color. When the parts that can change color do not change color, their base color is the same as that of the parts that do not change color.

[0015] Thus, after the color change, the changed color and the unchanged part of the rotating cleaning component are displayed alternately, making the visual effect more obvious.

[0016] Furthermore, the color-changing area can be set to change to multiple colors, changing color according to different temperature stages. For example, when the temperature is between 40℃ and 60℃, the color-changing area is red, and when the temperature is above 60℃, the color-changing area changes to black. In this way, users can see the changes more intuitively through the cleaning component.

[0017] Optionally, the cleaning system is configured to have a self-cleaning mode, including a hot water self-cleaning mode, in which the cleaning components are configured to change color in at least a portion of their area.

[0018] In hot water self-cleaning mode, the second heating element and water pump operate. The water pump provides power for the flow of clean water to the cleaning tank, and the second heating element heats the clean water flowing into the cleaning tank. The cleaning element's temperature rises under the influence of the hot water in the clean water tank, resulting in a color change.

[0019] Optionally, the cleaning device is configured to have a hot water cleaning function when cleaning the surface to be cleaned, and the cleaning components are configured to change color in at least a portion of the area after the hot water cleaning function is activated.

[0020] During the cleaning process after the cleaning equipment detaches from its base, if a specific area (such as the kitchen) is being cleaned, or if stubborn stains are encountered, the hot water cleaning function can be activated. In hot water cleaning mode, the distributor sprays hot water onto the cleaning components. Hot water is more effective at softening grease and stubborn stains, improving cleaning results. The cleaning components, affected by the hot water, heat up and change color. Of course, the hot water cleaning function is used throughout the entire cleaning process (regardless of whether stubborn stains are encountered).

[0021] The hot water sprayed from the water distributor can be heated instantly by the second heating element on the cleaning equipment, or it can be hot water stored in the first clean water tank.

[0022] Optionally, the cleaning assembly includes a support member and a cleaning element located outside the support member, wherein at least a portion of the cleaning element is color-changing.

[0023] Optionally, at least a portion of the cleaning component is made of a material containing a thermochromic dye.

[0024] Optionally, the cleaning component includes a woven structure made of woven fibers, at least a portion of which are fibers that change color with temperature.

[0025] Optionally, the area of ​​the color-changing region of the cleaning component is smaller than the area of ​​the non-color-changing region.

[0026] Optionally, the cleaning component is a roller brush, the support component includes a support shaft, the cleaning component is a cylindrical cleaning component sleeved outside the support shaft, and the color-changing area is distributed along the outer periphery of the roller brush.

[0027] Optionally, the variable color area surrounds the outer periphery of the roller brush at an angle greater than or equal to 300°.

[0028] Optionally, the color change of the cleaning component is reversible. Attached Figure Description

[0041] In this invention, 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. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] See Figure 1 The cleaning system includes a base 200 and a cleaning device. The base 200 supports the cleaning device, which can perform self-cleaning and charging functions on the base 200. When the surface to be cleaned needs to be cleaned, the cleaning device is detached from the base 200.

[0043] The cleaning device includes a body 130, a floor brush 120, and a handle. The floor brush 120 includes a brush body 20 and a cleaning component 121, which is located on the brush body 20. Generally, during cleaning, the user holds the brush in the handle and swings the body 130 to move the brush body 20. During the movement of the brush body 20, the cleaning component 121 comes into contact with different areas of the surface to be cleaned, thus achieving the cleaning work.

[0044] See Figure 1 As indicated by the middle arrow, during the cleaning process, the floor brush 120 can move forward or backward in a roughly horizontal direction on the surface to be cleaned by the user applying push or pull motions to the handle.

[0045] Surfaces to be cleaned include, but are not limited to, floors, carpets, walls, and tabletops.

[0046] For ease of description, the surface to be cleaned will be the ground as an example below.

[0047] The cleaning component 121 may be a roller brush, a conveyor belt, a cleaning disc, etc., but is not limited to these.

[0048] The base 200 includes a base body and a drying component disposed on the base body. The drying component includes a first heating component, a drying air duct and a fan. The airflow blown out by the fan is heated by the first heating component and then blown toward the cleaning component 121 to perform thermal drying on the cleaning component 121.

[0049] The first heating element can be an electric heating wire, a PTC (Positive Temperature Coefficient Heating) heating element, or an infrared heating element, but is not limited to these.

[0050] At least one of the base 200 and the cleaning device is equipped with a second heating element for heating clean water. The heated clean water can be pumped and piped to the cleaning tank of the base 200. The hot water in the cleaning tank is used to wash the cleaning component 121 during the self-cleaning process, which improves the cleaning effect of the cleaning component 121. The heated clean water can also be pumped to the water distributor 23 of the floor brush 120. The water distributor 23 sprays hot water onto the cleaning component 121. The cleaning component 121, wetted by the hot water, can better soak, soften, and even dissolve the stains on the surface to be cleaned during the cleaning process, reducing the adhesion of the stains and improving the cleaning effect.

[0051] Optionally, the second heating component includes a boiler.

[0052] In some embodiments, the cleaning device is provided with a first clean water tank, which stores clean water. The aforementioned hot water, such as the hot water used to clean the cleaning component 121 during the self-cleaning process and the hot water used to wet the cleaning component 121 during the floor cleaning process by the floor brush 120, can all come from the first clean water tank. Of course, the first clean water tank may not supply water for the self-cleaning process, and the water used for the self-cleaning process may also be provided by a second clean water tank on the base 200.

[0053] The cleaning equipment may also include a suction motor and a wastewater tank. The wastewater tank is used to collect wastewater generated during the cleaning process, which is generally a solid-liquid mixture. The suction motor provides negative pressure, and the floor brush body 20 is equipped with a suction port 40. The suction motor and the suction port 40 are connected by a suction channel. Under the negative pressure suction generated by the suction motor, garbage, wastewater, etc., are sucked into the wastewater tank through the suction port 40 and the suction channel.

[0054] The suction motor can also suck away sewage in the cleaning tank on the base 200, or sewage and debris such as hair adsorbed by the cleaning component 121 during the self-cleaning process.

[0055] In some embodiments, the cleaning component 121 includes a roller brush, and the cleaning device may also include a roller brush motor, which can drive the roller brush to rotate during the cleaning process to assist in cleaning. Alternatively, the roller brush motor can also drive the roller brush to rotate during the self-cleaning process to assist in the self-cleaning of the roller brush.

[0056] The cleaning device can establish a communication connection with the base 200. For example, the base 200 has a first transmission port, and the cleaning device has a second transmission port. When the cleaning device is placed on the base 200, the first and second transmission ports connect to enable information transmission between the cleaning device and the base 200, achieving self-cleaning and charging. The first and second transmission ports can both be communication interfaces, or they can be a combination of a communication interface and a charging interface.

[0057] The self-cleaning process of the cleaning device on the base 200 can be executed by a controller installed in the cleaning device, a controller installed in the base 200, or a server corresponding to the cleaning device and base 200. This server is located in the cloud, connects to the cleaning device via a network, and issues user commands to the cleaning device and base 200, or forwards user commands sent by the user through a terminal device (such as a mobile phone, wearable device, or computer) to the cleaning device and base 200.

[0058] The controller described above may include a microcontroller unit (MCU). Of course, the controller may also include other devices capable of control functions.

[0059] As mentioned earlier, cleaning equipment involves various heating scenarios during floor cleaning and self-cleaning processes. For example, self-cleaning involves hot drying and hot washing, while floor cleaning uses hot water. Currently, these heating scenarios primarily rely on temperature sensors to monitor the temperature. These sensors interact with a controller to control the temperature, but users cannot obtain information about the heating status, resulting in poor interactivity. A readily conceivable interaction method is voice prompts, but voice prompts have many limitations, such as high cost and noise. To at least improve the above problems, this application provides the following technical solutions.

[0060] Example 1

[0061] The cleaning system provided in Example 1 includes: a cleaning device and a base 200 adapted to the cleaning device; the cleaning device includes a floor brush 120, the floor brush 120 includes a floor brush body 20 and a cleaning component 121 disposed on one side of the floor brush body 20, the floor brush body 20 is provided with a suction port 40 for sucking up dirt from the surface to be cleaned; the cleaning system is configured to have a drying mode, in which the cleaning device is configured to be disposed on the base 200, and the base 200 is configured to dry the cleaning component 121; and, in the drying mode, at least a portion of the cleaning component 121 away from the suction port 40 may change color.

[0062] Based on the foregoing description, in the drying mode, the first heating component in the drying assembly operates. The airflow blown out by the fan is heated by the first heating component to form a hot airflow, which is then blown along the drying air duct toward the cleaning component 121. The cleaning component 121 is affected by the hot airflow, causing its temperature to rise and its color to change. The color change is visible; for example, the color change of the cleaning component 121 can be observed by the user through a window, thus reminding the user that the current stage is hot drying.

[0063] Users can see the cleaning component 121 change color as the temperature rises, allowing them to visually perceive whether they are using the drying mode, hot water self-cleaning mode (mentioned below), or hot water cleaning function (mentioned below), thus improving the interactive experience. Moreover, this interaction method is effective and cost-efficient.

[0064] For example, the cleaning component 121 is a roller brush, and the floor brush 120 generally has a roller brush cover above the roller brush. The roller brush cover is made of transparent material and can serve as a window for the user to observe whether the cleaning component 121 has changed color. Of course, the roller brush cover also helps to form a sealed air duct, improves the dirt suction capacity, assists in removing tangled objects from the roller brush, and prevents dirt from being thrown out.

[0065] Color changes can also be used to warn of damage to the cleaning system. For example, if the cleaning component 121 does not change color in drying mode, it may indicate that the first heating component is damaged or the heating effect is poor, preventing the cleaning component 121 from reaching the color-changing temperature.

[0066] Meanwhile, the color-changing position can be set to at least a part of the area away from the suction port 40, that is, the opposite side after suction. The cleaning component can calculate or control its stopping position during rotation. In this way, by controlling the setting of the color-changing part on the opposite side of the suction port 40, the user can more easily observe the changes of the cleaning component 121.

[0067] Furthermore, in some embodiments, the cleaning component 121 may be provided with color-changing areas at equal intervals around the axis, ensuring that the color change can be seen on the opposite side of the suction port 40 after the cleaning component stops.

[0068] On the other hand, not all cleaning components are set to be color-changing; that is, cleaning component 121 may include parts that do not change color (i.e., such as...). Figure 2 and Figure 3 The non-color-changing area 132 shown) and the color-changing parts (i.e., as shown) Figure 2 and Figure 3 The variable color area 131 shown has the same background color as the non-variable color area when the variable color area does not change color.

[0069] Thus, after the color change, the changed color and the unchanged part of the rotating cleaning component are displayed alternately, making the visual effect more obvious.

[0070] Furthermore, the color-changing area 131 can be set to change to multiple colors, changing color according to different temperature stages. For example, when the temperature is between 40°C and 60°C, the color-changing area 131 is red, and when the temperature is above 60°C, the color-changing area 131 changes to black. In this way, users can see the changes more intuitively through the cleaning component 121.

[0071] The color of the cleaning component 121 after the change should be a color that is significantly different from that of the base 200, the floor brush, and any areas of the cleaning component 121 that have not changed color (if any). For example: red, yellow, orange, purple, or blue.

[0072] Red is preferred, meaning that the red color is used to alert users when there is a temperature change. Since the bristles get dirty easily, gray bristles are often used so that even if the bristles get dirty, it won't be very noticeable. The red color will create a significant difference from the base color of the bristles, allowing users to observe the change more clearly.

[0073] Meanwhile, red is more inclined to be dark. When drying is carried out using infrared drying devices, red is more likely to absorb heat. Therefore, red can be used in conjunction with more drying methods. For example, when using a base with an infrared drying component, the color-changing area that can change color to red can work with the base to achieve faster and more efficient drying of the cleaning component 121.

[0074] In some alternative embodiments, the cleaning system is configured to have a self-cleaning mode, including a hot water self-cleaning mode, in which the cleaning component 121 is configured to change color in at least a portion of its area.

[0075] Based on the foregoing description, in the hot water self-cleaning mode, the second heating element and the water pump operate. The water pump provides power for the flow of clean water to the cleaning tank, and the second heating element heats the clean water flowing into the cleaning tank. The cleaning component 121 experiences a temperature increase under the influence of the hot water in the clean water tank, resulting in a color change.

[0076] For example, the self-cleaning mode includes a hot water self-cleaning mode and a drying mode, wherein the drying mode is executed after the hot water self-cleaning mode.

[0077] In some alternative embodiments, the cleaning device is configured to have a hot water cleaning function when cleaning the surface to be cleaned, and includes that, after the hot water cleaning function is activated, the cleaning component 121 is configured to change color in at least a portion of its area.

[0078] The fact that some areas here can change color can be ensured by setting most areas of the cleaning component 121 to change color, so that at least the exposed cleaning component 121 can change color during the slow rotation of the cleaning component 121 or after the cleaning component 121 stops rotating, so that the user can observe it.

[0079] Alternatively, by calculating the exposed portion of the cleaning component 121 after installation, at least the aforementioned portion can be set as a color-changing area, while controlling the aforementioned color-changing area to be exposed and observable each time the cleaning component 121 stops.

[0080] During the cleaning process after the cleaning equipment leaves the base 200, if a specific area (such as the kitchen) is being cleaned, or if stubborn stains are encountered, the hot water cleaning function can be activated. In hot water cleaning mode, the water distributor 23 sprays hot water onto the cleaning component 121. Hot water has a better softening effect on oil stains and stubborn stains, improving the cleaning effect. The cleaning component 121, affected by the hot water, experiences a temperature increase and a color change. Of course, the hot water cleaning function is used throughout the entire floor cleaning process (regardless of whether stubborn stains are encountered).

[0081] The hot water sprayed from the water distributor 23 can be heated instantly by the second heating component on the cleaning equipment, or it can be hot water stored in the first clean water tank.

[0082] In the hot water self-cleaning mode, drying mode, and hot water cleaning function, the colors of the cleaning components 121 after color change can all be the same, two by two, or each by one.

[0083] In some alternative embodiments, the color change of the cleaning component 121 is reversible. During the floor cleaning process, the initial color of the cleaning component 121 is a first color. After the hot water cleaning function is activated, the cleaning component 121 changes to a second color. If the hot water cleaning function is deactivated and the temperature of the cleaning component 121 drops below the color-changing temperature, the cleaning component 121 reverts to the first color. This process repeats, allowing the color-changing function of the cleaning component 121 to be reused repeatedly.

[0084] Similarly, when the cleaning device is placed on the base 200, after the drying mode or hot water self-cleaning mode stops and the temperature of the cleaning component 121 drops below the discoloration temperature, the color of the cleaning component 121 can be restored.

[0085] "Color change temperature" can be understood as the temperature point or temperature range at which the cleaning component 121 undergoes a significant color change. The color change temperature is related to the color-changing material used in the cleaning component 121, and the color change temperature can be 40℃, 45℃, 50℃, 55℃, 60℃, or 65℃, etc.

[0086] In some alternative embodiments, the cleaning component 121 includes a support 50 and a cleaning component 10 located outside the support 50, the cleaning component 10 being color-changing in at least a portion of its area.

[0087] The cleaning component 10 is the part of the cleaning assembly 121 that contacts the ground to clean it. The cleaning component 10 is generally in direct contact with the drying hot airflow or hot water, resulting in significant temperature changes. Furthermore, the cleaning component 10 is located on the outside, making it easier to observe. For these reasons, the cleaning component 10 is designed to be color-changing, providing both better visual and color-changing effects.

[0088] The support member 50 is the carrier for installing and fixing the cleaning component 10, and the support member 50 is connected to the floor brush body 20.

[0089] In some alternative embodiments, at least a portion of the cleaning element 10 is made of a material containing a thermochromic dye.

[0090] Generally, the cleaning component 10 is a mop. When dyeing the mop, a thermochromic agent is added to the dye to dye the mop. After dyeing, the mop is wrapped around the support component 50. When the cleaning system is in drying mode or hot water self-cleaning mode, or when the cleaning equipment uses the hot water cleaning function, the mop will change color when the temperature is higher than the color-changing temperature set by the thermochromic agent. For example, when the temperature reaches 30 degrees Celsius, the color of the mop can change from purple to red.

[0091] In some alternative embodiments, the cleaning component 10 includes a woven structure made of woven fibers, at least a portion of which are fibers that change color with temperature.

[0092] For example, temperature-sensitive color-changing fibers are woven together with ordinary non-color-changing fibers to form a cloth, thus creating the cleaning component 10. The above is merely an example, and how the color-changing cleaning component 10 is made is not intended to limit this application.

[0093] In some alternative embodiments, the area of ​​the color-changing region 131 of the cleaning component 10 is smaller than the area of ​​the non-color-changing region 132.

[0094] Compared to the fact that all areas of the cleaning component 10 can be colored, the fact that only some areas of the cleaning component 10 can be colored can reduce or even avoid the phenomenon of color confusion caused by uneven heating.

[0095] For example, the area of ​​the color-changing region 131 of the cleaning component 10 accounts for 1%-80% of the total area of ​​the cleaning component 10, for example: the area of ​​the color-changing region 131 of the cleaning component 10 accounts for 1%, 5%, 10%, 15%, 20%, 30% or 50% of the total area of ​​the cleaning component 10.

[0096] In some alternative embodiments, the cleaning component 121 is a roller brush, the support member 50 includes a support shaft, the cleaning member 10 is a cylindrical cleaning member 10 sleeved outside the support shaft, and the color-changing area 131 is distributed along the outer periphery of the roller brush.

[0097] Figure 5 A hollow support shaft is shown as an example, the two ends of which can be connected to the floor brush body 20 via the connecting arm assembly 30.

[0098] Whether during the self-cleaning process or the floor cleaning process, the roller brush is basically in a rotating state. The color-changing area 131 is set along the circumference of the roller brush, so the color-changing area is not easily blocked.

[0099] In some alternative embodiments, the variable color area 131 surrounds the outer periphery of the roller brush at an angle greater than or equal to 200°.

[0100] For example, the variable color region 131 surrounds the outer periphery of the roller brush at an angle greater than or equal to 250°, 300°, or 320°. In some preferred implementations, the variable color region 131 surrounds the outer periphery of the roller brush approximately 360°.

[0101] In some alternative embodiments, the color-changing region 131 includes a sub-color-changing region that extends along the axial direction of the support shaft. For example, the color-changing region 131 is a spiral ribbon-like region that extends around the axis of the roller brush and along the axial direction of the roller brush.

[0102] Or, see Figure 2 and Figure 3 The color-changing region 131 includes at least two sub-color-changing regions, which are spaced apart along the axial direction of the support shaft; the sub-color-changing regions are distributed along the outer periphery of the cleaning component 121. Figure 2 In the middle, there are multiple sub-color-changing areas, each of which is a roughly circular band-shaped area, and these circular band-shaped areas are roughly coaxial with the roller brush. Figure 3 In this embodiment, there are multiple sub-color-changing regions, each of which is a roughly linear band-shaped area parallel to the axis of the brush. The shape and number of sub-color-changing regions in this embodiment are merely illustrative and are not intended to limit the scope of this application.

[0103] Example 2

[0104] Example 2 provides a cleaning device, which includes a floor brush 120 and a cleaning assembly 121. The cleaning device of Example 2 can be an improvement on Example 1, and the following mainly describes the differences between Example 2 and Example 1.

[0105] Of course, the cleaning device of Embodiment 2 can be independent of Embodiment 1. For example, the cleaning component 121 of the cleaning device in Embodiment 2 may not have a color-changing function.

[0106] See Figure 4 and Figure 5 The cleaning component 121 includes a support member 50 and a cleaning component 10. The cleaning component 10 includes a cleaning layer 13 and an absorbent layer 12. The absorbent layer 12 is located between the cleaning layer 13 and the support member 50. The cleaning layer 13 includes bristles for contacting and cleaning the surface to be cleaned. Liquid can pass through the cleaning layer 13 and be absorbed by the absorbent layer 12.

[0107] To improve the cleaning effect on the ground, the cleaning layer 13 needs to have greater friction with the ground; this can be understood as the cleaning layer 13 needing to be "hard." However, a "harder" cleaning layer 13 has poor water absorption. Conversely, increasing the water absorption of the cleaning layer 13 would affect the cleaning effect. The cleaning component 10 of this application embodiment includes a cleaning layer 13 and a water-absorbing layer 12, which can resolve the contradiction between cleaning effect and water absorption effect. It can improve the ability to absorb wastewater and reduce water stains while ensuring the cleaning effect.

[0108] The brush bristles can better scrape away stains adhering to the ground, separating the stains from the surface, making them easier to be sucked away by negative pressure, ensuring a cleaning effect. Because the cleaning component 121 has an added absorbent layer 12, and the cleaning layer 13 is permeable to liquids such as wastewater, the absorbent layer 12 can better absorb wastewater from the ground. This method of improving water stain residue is simple, reliable, and low-cost.

[0109] Cleaning component 121, exemplified by a roller brush, is shown below. Figure 6 During the cleaning process, the roller brush generally rotates forward (i.e., Figure 6 (Indicated as counterclockwise). Using the approximate point of tangency between the distributor 23 and the roller brush and the ground O as the boundary, the circumference of the roller brush is roughly divided into a clean section L2 and a dirty section L1. After the clean section L2 moves forward to the ground, it carries the cleaning liquid from the distributor 23 to the ground. The stains on the ground are softened and cleaned away. Part of the wastewater is sucked away by the suction port 40, and the other part is sucked away by the absorbent layer 12, while the previously clean section L2 gradually becomes the dirty section L1. After the dirty section L1 passes the scraper 22 (mentioned below) above the suction port 40, the scraper 22 squeezes the cleaning component 10, squeezing out the wastewater from the absorbent layer 12. The squeezed-out wastewater is sucked away from the suction port 40 under negative pressure. The absorbent layer 12, after the wastewater is squeezed out, can continue to absorb wastewater in the next rotation, and so on.

[0110] In some embodiments, the cleaning layer 13 includes an absorbent material. That is, the cleaning layer 13 is also a type of absorbent layer 12, so the cleaning assembly 121 includes two absorbent layers 12. The cleaning layer 13 absorbs water once, and the absorbent layer 12 absorbs water a second time, further improving the cleaning effect on residual water stains.

[0111] The cleaning layer 13 can be a velvet cloth, such as nylon velvet, but is not limited to this. The bristles can be the inherent fibers on the surface of the velvet cloth, or they can be formed by flocking.

[0112] The length and shape of the bristles can be adjusted according to the actual application, and the specific structure of the bristles is not intended to limit the embodiments of this application.

[0113] The bristles on the surface of the cleaning layer 13 can be all soft bristles, or they can include both soft and hard bristles.

[0114] For example, the absorbent layer 12 has a greater absorbent capacity than the cleaning layer 13. It is understood that, while ensuring the cleaning ability of the cleaning layer 13, the higher the absorbent capacity of the cleaning layer 13, the better.

[0115] The absorbent layer 12 is made of porous materials such as sponge, which have good water absorption and do not easily harden after drying. Examples include polyurethane (PU) sponge and polyethylene (PVA) alcohol sponge.

[0116] In conjunction with the foregoing description, the absorbent layer 12 is also elastic, so that after the liquid adsorbed by the absorbent layer 12 is squeezed out, the absorbent layer 12 can return to its original size, ensuring that the cleaning component 121 has a more stable size.

[0117] In some embodiments, the cleaning layer 13 has pores that allow liquid to pass through. The pores can be holes provided in the cleaning layer 13, or gaps between structural units in the cleaning layer 13 (such as gaps between woven fibers).

[0118] In some embodiments, the cleaning layer 13 further includes a substrate, bristles are disposed on the substrate, and the bristles and the absorbent layer 12 are located on opposite sides of the substrate, the substrate having pores.

[0119] Exemplarily, the bristles can be implanted onto the substrate by means of bristle attachment. In the embodiment illustrated in this application, the substrate is directly fitted over the absorbent layer 12. In other implementations, the absorbent layer 12 may also be indirectly fitted over the absorbent layer 12.

[0120] In some embodiments, the substrate is a mesh. The mesh substrate has better water permeability, which can effectively ensure the water absorption effect of the absorbent layer 12. After passing through the bristles and mesh in sequence, the liquid permeates through the entire cleaning layer 13, realizing the adsorption of sewage by the absorbent layer 12.

[0121] In some alternative embodiments, the absorbent layer 12 is configured to be elastically deformable, so that when the cleaning assembly 121 is cleaning hard stains, the absorbent layer 12 can deform to assist the suction port in cleaning the hard stains.

[0122] Hard stains include soybeans, peanuts, pebbles, etc. When the cleaning component 121 comes into contact with these hard stains, the absorbent layer 12 undergoes elastic deformation, reducing the hardness caused by the cleaning component 121 "pushing" away the hard stains. In other words, the elastic deformation of the absorbent layer 12 can better "wrap" the hard stains and deliver them to the suction port 40 for absorption.

[0123] If a suitable material is selected, such as a sponge, the absorbent layer 12 can have good water absorption capacity as well as good elastic deformation capacity.

[0124] In some embodiments, the thickness of the absorbent layer 12 is 0.8mm-6mm. This thickness range allows the absorbent layer 12 to effectively maintain its water absorption capacity while maintaining a relatively thin size. Different thicknesses of the absorbent layer 12 absorb different amounts of water, and the thickness of the absorbent layer 12 can be adjusted according to the actual machine model and water volume. For example, the thickness of the absorbent layer 12 can be 0.8mm, 1mm, 2mm, 3mm, 4mm, 5mm, or 6mm, etc.

[0125] See Figure 6 The floor brush 120 includes a floor brush body 20 and a cleaning component 121 as described in Embodiment 1, and the cleaning component 121 is connected to the floor brush body 20.

[0126] See Figure 4 In some optional embodiments, the cleaning component 121 is a roller brush, and the floor brush 120 also includes a water distributor 23 and a scraper 22 disposed on the floor brush body 20. The scraper 22 is located above the suction port 40, and the water distributor 23 is located above the scraper 22. The scraper 22 is interference-fitted with the roller brush. During the cleaning process, the roller brush passes through the suction port 40, the scraper 22 and the water distributor 23 in sequence. The water distributor 23 is used to spray cleaning liquid onto the roller brush, and the scraper 22 is used to squeeze out the liquid in the water-absorbing layer 12.

[0127] As mentioned earlier, during the cleaning process, the dirt on the roller brush is first sucked away through the suction port 40 under negative pressure. The remaining dirt moves to the scraper 22 as the roller brush rotates. The scraper 22 can scrape off solid debris from the dirty section L1 and also squeeze out the wastewater absorbed by the cleaning layer 13 and the absorbent layer 12. After this action is completed, the roller brush is sprayed with cleaning liquid through the water distributor 23 to facilitate the next cleaning of the floor.

[0128] See Figure 6In some alternative embodiments, the floor brush 120 further includes comb teeth 21 located above the suction port 40 and below the scraper 22. The comb teeth 21 are used to clean the cleaning layer 13. The interference fit between the comb teeth 21 and the roller brush is smaller than the interference fit between the scraper 22 and the roller brush. The flat scraper with a larger interference fit with the roller brush can more effectively squeeze out the wastewater adsorbed by the suction layer 12 and the cleaning layer 13.

[0129] For example, the scraper 22 can be made of metal, and the metal scraper 22 has better hardness, which is more conducive to squeezing water.

[0130] As the roller brush operates, see Figure 6 Clean water (i.e., cleaning liquid) flows from the outlet 231 of the water distributor 23 onto the roller brush. The roller brush contacts the ground, rubbing and adsorbing dirt and debris to clean the ground. When the roller brush reaches the comb teeth 21 in the dirty water section, the teeth of the comb teeth 21 hook the hair to prevent it from getting tangled in the roller brush. The hair scraped off by the comb teeth 21 is sucked away by the suction port 40. The scraper 22 is located above the comb teeth 21. The scraper 22 is placed roughly horizontally, also known as a flat scraper. The distance between the flat scraper and the roller brush is closer (i.e., the interference fit between the flat scraper and the roller brush is greater), which can effectively squeeze out the water in the water absorption layer 12 and the residual water in the cleaning layer 13. At the same time, the suction port 40 sucks away the squeezed-out water.
