[0038] The embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments of the present disclosure, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0039] It should be noted that all the directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present disclosure are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and the directional indications will change accordingly when the certain posture changes.

When an element is referred to as being “connected to” another element, it can be directly connected to the other element or can have a middle element.

[0041] In addition, the descriptions involving “first”, “second”, etc. in the present disclosure are only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as “first”, “second” can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present disclosure.

[0042] The existing cleaning equipment such as the scrubber often has the problem of uneven liquid supply when supplying liquid to the roller brush. This will cause the liquid content of different parts of the roller brush (such as in the axial direction) to be inconsistent, and in the cleaning process, the cleaning area corresponding to the part with high liquid content may be over-wet, causing too much water stain to remain on the ground after cleaning, while the area with low liquid content may not have good cleaning effect, and cannot effectively remove stains, thereby affecting the overall cleaning effect and efficiency, and being difficult to meet the user's demand for high-quality cleaning.

[0043] To address the above problems in the prior art, the embodiments of the present disclosure provide a cleaning device 100, which can improve the uniformity of liquid supply to the roller brush to some extent, so as to uniformly and fully wet the roller brush and improve the cleaning effect. The cleaning device 100 disclosed herein is a device with cleaning function, for example, the cleaning device can be a handheld scrubber, a cleaning robot, a scrubbing robot, a mopping machine, etc.

[0044] With reference to Figure 1 and Figure 9 , the cleaning device 100 comprises a device body 110, a roller brush 120 and a liquid uniformizing structure 130; see Figure 2 and Figure 3 , the device body 110 is provided with a liquid outlet 111; the device body 110 outputs liquid through the liquid outlet 111 to supply liquid to the roller brush 120 to wet it, so that the roller brush 120 cleans the surface to be cleaned or the roller brush 120 is self-cleaning. The liquid can be water or cleaning liquid or a mixture of water and cleaning liquid, etc., which is not limited in the present embodiment.

[0045] Specifically, the device body 110 is internally provided with a liquid storage structure, which is in communication with the liquid outlet 111 and its working state can be precisely controlled. When the liquid sending program is started, the liquid storage structure can deliver liquid to the liquid outlet 111 according to the preset mechanism, thereby ensuring that the liquid outlet 111 stably outputs the liquid required for cleaning; and after the pause liquid sending instruction is issued, the liquid storage structure immediately stops the liquid delivery action to the liquid outlet 111, so as to effectively control the liquid supply. Exemplarily, see Figure 8 and Figure 9 , the liquid storage structure is a clean water tank 140 provided on the device body 100, which is detachably or non-detachably installed on the device body 100, for example, when the clean water tank 100 is detachable, the user first detaches it, then fills it with clean water and / or cleaning liquid, etc. When the liquid sending program is started, the peristaltic pump is controlled to work to draw the water in the clean water tank 140 to the liquid outlet 111 to flow to the roller brush 120; when the pause liquid sending instruction is issued, the peristaltic pump is controlled to pause working.

[0046] The liquid outlet 111 can be provided in plurality, and the plurality of liquid outlets 111 are arranged in the axial direction of the roller brush 120 to supply liquid to the plurality of positions of the roller brush 120. The plurality of liquid outlets 111 correspond to the positions of the roller brush 120, so that the water flowing out of the liquid outlet 111 can directly reach the roller brush 120. For example, the plurality of liquid outlets 111 are uniformly arranged along the axial direction of the roller brush 120 to make the roller brush 120 be soaked as evenly as possible. However, since the diameter of the liquid outlet 111 is generally small, there is little or no liquid between the adjacent two liquid outlets 111, so that the part of the roller brush 120 opposite to the position cannot be soaked or cannot be sufficiently soaked, thereby causing uneven water marks when mopping.

[0047] The roller brush 120 is rotatably arranged on the device body 110 and is arranged opposite to the liquid outlet 111. The roller brush 120 is used for cleaning the surface to be cleaned. The roller brush 120 is made of a suitable material, such as a fiber material having good water absorption and cleaning ability, and is connected to the device body 110. In operation, the roller brush 120 can be in full contact with the surface to be cleaned, and the liquid absorbed by the roller brush 120 is uniformly coated on the surface to be cleaned by rotation, and the stains on the surface to be cleaned are wiped by the liquid and the velvet structure, thereby achieving the cleaning function.

[0048] For example, referring to Figure 8 , the roller brush 120 can be a partially hollow cylindrical body. One end of the roller brush 120 is sleeved on the driving motor 150 and is connected thereto. The other end of the roller brush 120 is rotatably connected to the device body 110. The driving motor 150 is fixedly installed on the device body 110. When the cleaning device performs a cleaning task, the driving motor 150 drives the roller brush 120 to rotate. The velvet on the surface of the roller brush 120 is soaked by the liquid flowing out of the liquid outlet 111, and then contacts the surface to be cleaned to achieve cleaning.

[0049] For example, referring to Figure 6 and Figure 7The liquid uniformizing structure 130 is arranged between the liquid outlet 111 and the rolling brush 120, communicates with the liquid outlet 111, and at least partially abuts against the rolling brush 120. The liquid uniformizing structure 130 comprises a shielding part 131, a liquid passing groove 131C, a liquid uniformizing table 132, and a liquid guiding part 133. The shielding part 131 covers the liquid outlet 111. The liquid passing groove 131C penetrates through opposite sides of the shielding part 131, so that the liquid flowing out of the liquid outlet 111 flows to the rolling brush 120 through the liquid passing groove 131C. The liquid uniformizing table 132 is formed at the liquid passing groove 131C and extends towards the rolling brush 120 to abut against the rolling brush 120. The liquid guiding part 133 is protrudingly arranged on the liquid uniformizing table 132, and the height of the liquid guiding part 133 protruding from the liquid uniformizing table 132 gradually decreases in a direction away from the liquid outlet 111, so as to guide the liquid flowing out of the liquid passing groove 131 to the direction away from the liquid outlet 111. In the space between the liquid outlet 111 and the rolling brush 120, the shielding part 131 of the liquid uniformizing structure 130 covers the surface of the liquid outlet 111, so as to separate the liquid outlet 111 from the rolling brush 120 and avoid the direct contact between the rolling brush 120 and the liquid outlet 111. Since the rolling brush 120 is covered with dust, hair and other dirt, if the rolling brush 120 directly contacts the liquid outlet 111, the liquid outlet 111 is easily blocked. The shielding part 131 can be made of a material with certain flexibility and corrosion resistance, such as high-quality rubber or high-strength plastic, which can effectively block the direct impact of the liquid and preliminarily disperse and buffer the liquid.

[0050] The liquid passing groove 131C is arranged to penetrate through opposite sides of the shielding part 131. The liquid passing groove 131C comprises a groove bottom wall 131C2 and groove side walls 131C1 connected with the groove bottom wall 131C2. The four groove side walls 131C1 are sequentially connected in a head-to-tail manner to form annular side walls. The liquid uniformizing table 132 is formed at the liquid passing groove 131C and arranged corresponding to the rolling brush 120. The liquid uniformizing table 132 extends towards the rolling brush 120, and the rolling brush 120 abuts against the liquid uniformizing table 132. The liquid uniformizing table 132 can be one of the four groove side walls 131C1 closest to the surface to be cleaned, or the liquid uniformizing table 132 can be a plane arranged on the lowest groove side wall 131C1 in the first direction (the first direction is perpendicular to the liquid uniformizing table 132 and away from the direction of gravity) among the four groove side walls 131C1, that is, the lowest groove side wall 131C1 closest to the surface to be cleaned. Alternatively, the liquid uniformizing table 132 can be a plane arranged on the lowest groove side wall 131C1 independently of the lowest groove side wall 131C1.

[0051] The rolling brush 120 rotates normally (for example, as shown in FIG. 2) during normal operation. Figure 1The rolling brush 120 rotates in the counterclockwise direction (as shown by the arrow) and contacts the liquid passage 131C and the liquid uniformizing platform 132 to absorb the liquid from the liquid uniformizing platform 132. The liquid guide 133 is provided in a protruding structure on the liquid uniformizing platform 132, and the shape of the liquid guide 133 can be a pyramid or other streamlined shape, which is used to guide the flow direction of the liquid flowing out of the liquid outlet 111. After the liquid flowing out of the liquid outlet 111 impacts the blocking part 131, the liquid flows along the liquid guide 133 to the liquid uniformizing platform 132.

[0052] For example, the liquid guide 133 is provided in a protruding structure on the side of the liquid uniformizing platform 132 away from the direction of gravity. For example, the liquid guide 133 is provided in a protruding structure on the liquid uniformizing platform 132 in the first direction, and the height of the liquid guide 133 protruding in the first direction from the liquid uniformizing platform 132 gradually decreases in the direction away from the liquid outlet 111, so as to guide the liquid flowing out of the liquid passage 131C in the direction away from the liquid outlet 111, where the first direction is perpendicular to the liquid uniformizing platform 132 and away from the direction of gravity.

[0053] The working principle of the liquid uniformizing structure 130 is as follows: when the liquid flows out of the liquid outlet 111, it is dispersed by impacting the blocking part 131, flows to the rolling brush 120 through the liquid passage 131C, and is guided by the liquid guide 133 provided in a protruding structure on the liquid uniformizing platform 132 to flow on the liquid uniformizing platform 132 and be uniformly spread, and the rolling brush 120 contacts the liquid passage 131C and the liquid uniformizing platform 132 during rotation to uniformly absorb the liquid from the liquid uniformizing platform 132.

[0054] The outer side edge of the liquid uniformizing platform 132 is relatively protruding, that is, extends in the direction toward the rolling brush 120, and when the rolling brush 120 contacts the liquid uniformizing platform 132, the bristles of the rolling brush 120 are pressed to form a cavity 134 above the liquid uniformizing platform 132 without the bristles of the rolling brush 120, so as to avoid the bristles of the rolling brush 120 being spread to directly contact the liquid outlet 111 and absorb the liquid flowing out of the liquid outlet 111, so that the liquid is uniformly spread on the liquid uniformizing platform 132 before being absorbed by the rolling brush 120. In addition, the cavity 134 can be used to store liquid, so that the liquid on the liquid uniformizing platform 132 is collected to a certain amount before being absorbed by the bristles of the rolling brush 120, so that the rolling brush 120 is uniformly wetted while being fully wetted.

[0055] The cleaning device 100 provided by the present disclosure effectively improves the uneven liquid supply to the rolling brush 120 by providing a unique liquid uniformizing structure 130 between the liquid outlet 111 and the rolling brush 120, including the blocking part 131, the liquid passage 131C, the liquid uniformizing platform 132, and the liquid guide 133, so that the rolling brush 120 can uniformly absorb the liquid during operation, thereby significantly improving the cleaning effect and efficiency, solving a series of problems caused by the uneven liquid supply of the existing cleaning device 100, and providing better cleaning services for users.

[0056] In some embodiments, referring to Figure 7 , the liquid guide portion 133 protrudes from the height of the liquid uniformizing table 132 and gradually decreases in at least one of the second direction and the third direction; the second direction is parallel to the axial direction of the rolling brush 120 and points away from the liquid outlet 111, and the third direction is parallel to the extension direction of the liquid uniformizing table 132 towards the rolling brush 120. For example, the second direction is indicated by the dotted arrow a in Figure 7 , and for the same liquid outlet 111, the second direction includes two opposite directions; the third direction is indicated by the dotted arrow b in Figure 7 .

[0057] It should be noted that the direction away from the liquid outlet 111 can be any direction between the second direction and the third direction, and the present disclosure does not limit it.

[0058] The above height gradient design of the liquid guide portion 133 allows the liquid to gradually change the flow direction and speed when flowing out of the liquid outlet 111 and passing through the liquid guide portion 133, so as to be more evenly distributed on the liquid uniformizing table 132 according to the height change of the liquid guide portion 133. Specifically, after the liquid flows out of the liquid outlet 111, it will first reach the higher part of the liquid guide portion 133. Due to the gradual decrease of the height of the liquid guide portion 133, the liquid will gradually flow to the lower part along the liquid guide portion 133. In this process, the flow rate and flow direction of the liquid will be constantly adjusted according to the height change of the liquid guide portion 133, so that the liquid flows towards the liquid uniformizing table 132 and is more evenly distributed on the liquid uniformizing table 132.

[0059] In some embodiments, referring to Figure 4 and Figure 5 , the liquid passing groove 131C is recessed on the side of the shielding portion 131 away from the liquid outlet 111; the liquid uniformizing table 132 is formed on the liquid passing groove 131C closest to the surface to be cleaned, that is, the lowest groove side wall 131C1 in the first direction, and the liquid guide portion 133 is formed with a liquid guide inclined surface 133M on the side facing the liquid passing groove 131C. For example, the liquid guide inclined surface 133M is in any direction between the second direction and the third direction, so as to guide the liquid towards the liquid uniformizing table 132.

[0060] Referring to Figure 7When the cleaning device 100 performs a cleaning task, liquid flows out of the liquid outlet 111, is dispersed by the shielding part 131, and enters the liquid passing groove 131C. After entering the liquid passing groove 131C, part of the liquid directly falls onto the surface of the liquid guiding part 133 under the action of gravity, and the other part impacts on the liquid guiding slope 133M of the liquid guiding part 133. The liquid guiding slope 133M uniformly disperses and guides the liquid to flow to the liquid uniformizing table 132. The two parts of the liquid are mixed on the liquid uniformizing table 132 and then are immediately dispersed, thereby enhancing the uniformity of the liquid. With the continuous inflow and flow of the liquid, a certain amount of liquid is gathered on the liquid uniformizing table 132, and the liquid uniformizing table 132 continuously and uniformly delivers the liquid to the rolling brush 120. The rolling brush 120 continuously absorbs the uniformly distributed liquid from the liquid uniformizing table 132 in the process of rotation.

[0061] The liquid passing groove 131C provides a space for buffering and preliminary dispersion of the liquid. After the liquid flowing out of the liquid outlet 111 enters the liquid passing groove 131C, the liquid is preliminarily dispersed in the groove due to the shape and space limitation of the groove, so that the liquid can be more uniformly distributed on the liquid uniformizing table 132. The liquid uniformizing table 132 extends from the groove side wall 131C1 of the liquid passing groove 131C to the groove bottom wall 131C2 of the liquid passing groove 131C. The liquid uniformly disperses in the liquid passing groove 131C, and then naturally flows along the liquid uniformizing table 132 of the groove side wall 131C1 away from the groove bottom wall 131C2. This design of flow direction conforms to the principle of gravity and inertia of the liquid, so that the flow of the liquid on the liquid uniformizing table 132 is more stable and smooth, further promotes the uniform distribution of the liquid on the rolling brush 120, and improves the consistency of the cleaning effect. On the other hand, dirt falling from the rolling brush 120 can be temporarily stored in the space of the liquid passing groove 131C to prevent the dirt from entering the liquid outlet 111 and causing blockage.

[0062] In some embodiments, with reference to Figure 1 and Figure 5 , the groove side wall 131C1 of the liquid passing groove 131C is inclined relative to the horizontal plane; or the liquid uniformizing table 132 is inclined relative to the horizontal plane. When the surface to be cleaned is a relatively flat plane, the groove side wall 131C1 of the liquid passing groove 131C can also be considered to be inclined relative to the surface to be cleaned; or the liquid uniformizing table 132 is inclined relative to the surface to be cleaned.

[0063] When the tank side wall 131C1 of the liquid passing tank 131C is arranged to be inclined relative to the horizontal plane, the tank side wall 131C1 at the lowest part of the inclined liquid passing tank 131C can guide the liquid to flow more smoothly from the liquid passing tank 131C to the rolling brush 120 by the action of gravity of the liquid. Due to the component force of gravity acting on the liquid on the inclined tank side wall 131C1, the liquid will naturally flow downward along the side wall, reducing the possibility of the liquid stagnating in the tank, so that the liquid can be continuously and stably supplied to the rolling brush 120. Moreover, when the liquid flows from the liquid passing tank 131C to the rolling brush 120, the inclined tank side wall 131C1 can make the liquid gradually spread and cover a wider area during the flow process. Exemplarily, the extension direction a1 of the tank side wall 131C1 at the lowest part away from the tank bottom wall 131C2 has an included angle a with the direction a2 of the tank bottom wall 131C2 pointing to the rolling brush 120 from the horizontal plane, and the included angle a is greater than 0° and less than 90°. Compared with the vertical tank side wall 131C1 (when the included angle a is 90°), the arrangement of the included angle a less than 90° can make the liquid have a certain tendency to spread laterally when leaving the liquid passing tank 131C, avoiding the liquid from being concentrated at a certain point or a small area to enter the rolling brush 120, so that the liquid is more uniformly distributed in the axial direction of the rolling brush 120. Compared with the horizontal tank side wall 131C1 (when the included angle a is 0°), the arrangement of the included angle a greater than 0° can make the liquid flow directly downward under the action of gravity, avoiding the liquid from being concentrated on the tank side wall 131C1 to reduce the flowability, so that the liquid can flow more quickly to the rolling brush 120. The range of the inclination angle a of the tank side wall 131C1 at the lowest part of the liquid passing tank 131C relative to the horizontal plane can be 5°-30°, for example, the inclination angle a of the tank side wall of the liquid passing tank 131C relative to the horizontal plane can be set to 10°, which is only exemplary, and the specific inclination angle value a can be set according to actual needs.

[0064] When the liquid leveling platform 132 is inclined relative to the horizontal plane, the liquid can naturally flow from the platform 132 to the roller brush 120 under its own gravity. The specific method of setting the liquid leveling platform 132 incline relative to the horizontal plane is similar to the setting of the lowest tank sidewall 131C1 described above, and will not be repeated here. This inclined design of the liquid leveling platform 132 provides a clear flow direction for the liquid, avoiding disordered flow or accumulation of the liquid on the platform 132. For example, when the cleaning equipment 100 is working, the liquid flowing out of the outlet 111 and guided by the guide section 133 will flow smoothly along the inclined liquid leveling platform 132 to the roller brush 120, reducing the resistance to liquid flow and ensuring that the liquid can reach the roller brush 120 efficiently. Furthermore, the inclined uniform distribution surface 132 allows the liquid to be more evenly distributed along the axial direction of the roller brush 120 as it flows towards the roller brush 120. Simultaneously, it allows the liquid on the uniform distribution surface 132 to accumulate to a certain amount before being absorbed by the roller brush 120, ensuring both uniform wetting and thorough wetting of the roller brush 120. When the liquid flows along the inclined uniform distribution surface 132, it contacts the roller brush 120 in a relatively dispersed manner. For example, the liquid flows from the higher end of the uniform distribution surface 132 towards the roller brush 120, gradually covering the surface of the roller brush 120 during this flow, rather than concentrating at a single point or in a localized area. The tilt angle α of the uniform liquid stage 132 relative to the horizontal plane can be in the range of 5° to 30°. For example, the tilt angle α of the uniform liquid stage 132 relative to the horizontal plane can be set to 10°. By combining the small tilt angle design of the uniform liquid stage 132 with the surface tension of the liquid, the liquid can accumulate a certain amount of liquid on the uniform liquid stage 132 and can also flow downward to spread out at the edge of the uniform liquid stage 132.

[0065] In some embodiments, refer to Figures 4 to 7 Multiple liquid outlets 111 are spaced upward along the axial direction of the roller brush 120. Multiple liquid-passing grooves 131C are provided on the shielding portion 131, and a flow-blocking portion 131B is provided between adjacent two liquid-passing grooves 131C. The multiple flow-blocking portions 131B are positioned opposite to the multiple liquid outlets 111 to block the flow and allow the liquid flowing from the liquid outlets 111 to flow through the liquid-passing grooves 131C to the roller brush 120. For example, a gap exists between the flow-blocking portion 131B and the liquid outlets 111, allowing the liquid flowing from the liquid outlets 111 to flow through the gap to the liquid-passing grooves 131C.

[0066] On the shielding part 131, since the liquid passing groove 131C adopts a groove design penetrating through the opposite two side surfaces of the shielding part 131 and is in communication with the liquid outlet 111, the liquid flowing out of the liquid outlet 111 can quickly enter the liquid passing groove 131C. The plurality of liquid passing grooves 131C are sequentially arranged along the axial direction of the rolling brush 120, and any two adjacent liquid passing grooves 131C are spaced apart by a flow blocking part 131B. The number of flow blocking parts 131B can be set according to the number of liquid outlets 111, and each liquid outlet 111 is covered by one flow blocking part 131B. The flow blocking part 131B realizes the flow blocking effect and guiding effect of the liquid of the liquid outlet 111. Specifically, when the liquid flows out of the liquid outlet 111, since the flow blocking part 131B is opposite to the liquid outlet 111, the liquid first impacts on the flow blocking part 131B, the flow blocking part 131B guides the liquid to change the flow direction, so that the liquid is uniformly dispersed and flows into the two adjacent liquid passing grooves 131C on the two sides, and flows along the liquid guiding part 133 to the liquid uniformizing platform 132.

[0067] Under the flow blocking and guiding effect of the flow blocking part 131B, the liquid flowing out of the liquid outlet 111 can smoothly enter the liquid passing groove 131C, avoiding the disorderly splashing of the liquid and the unstable influence of the impact energy on the liquid uniformizing structure 130, ensuring that the liquid flows to the liquid uniformizing platform 132 in a relatively stable and uniform state, which is beneficial to maintaining the stability and reliability of the entire liquid uniformizing process. In addition, since the flow blocking part 131B covers the liquid outlet 111, when the garbage carried by the rolling brush 120 is pulled to the flow blocking part 131B, the flow blocking part 131B contacts the garbage and blocks the garbage outside the liquid outlet 111, which can avoid the garbage being directly squeezed into the liquid outlet 111, thereby preventing the liquid outlet 111 from being blocked and ensuring the normal liquid supply of the liquid outlet 111.

[0068] In some embodiments, referring to Figures 4 to 7 , the plurality of liquid passing grooves 131C correspond to the plurality of liquid uniformizing platforms 132, and each liquid uniformizing platform 132 is provided with a liquid guiding part 133 at each end. This design makes the liquid entering each liquid passing groove 131C uniformly dispersed and guided on the corresponding liquid uniformizing platform 132. Specifically, after the liquid flows out of the liquid outlet 111, it is divided by the flow blocking part 131B into each liquid passing groove 131C. The liquid entering the liquid passing groove 131C flows to the corresponding liquid uniformizing platform 132 and is guided by the liquid guiding parts 133 on both sides of the liquid uniformizing platform 132. The liquid guiding part 133 converts the impact force of the liquid into the power of spreading along the surface, so that the liquid uniformly covers the liquid uniformizing platform 132 and then smoothly flows along the liquid uniformizing platform 132 to the rolling brush 120.

[0069] Alternatively, in some embodiments, each flow blocking part 131B is provided with a liquid guiding part 133 on each side thereof; after the liquid flows out of the liquid outlet 111, the liquid is blocked by the flow blocking part 131B and is divided into two parts, and the liquid guiding parts 133 on the two sides of the flow blocking part 131B can immediately guide the divided liquid to flow towards the liquid uniformizing table surface 132 corresponding to the liquid guiding part 133.

[0070] Alternatively, in some embodiments, each flow blocking part 131B is located between two adjacent liquid guiding parts 133. After the liquid flowing out of the liquid outlet 111 impacts on the flow blocking part 131B, the liquid is blocked and divided into two parts, and the two adjacent liquid guiding parts 133 guide the divided liquid to flow towards the liquid uniformizing table surface 132 corresponding to the liquid guiding part 133.

[0071] In some embodiments, referring to Figure 7 , the liquid guiding part 133 is provided with a liquid guiding groove 133C, and the liquid guiding groove 133C is arranged in a direction away from the liquid outlet 111. The interface shape of the liquid guiding groove 133C can be semicircular, rectangular or other shapes optimized by fluid mechanics, and the depth and width of the liquid guiding groove 133C can be designed according to actual needs, which are not limited herein. In addition, the number of liquid guiding grooves 133C can be one or more, which is set according to actual needs. When the number of liquid guiding grooves 133C is set to be multiple, the multiple liquid guiding grooves 133C are arranged in sequence and at intervals.

[0072] When the liquid on the liquid uniformizing table surface 132 accumulates and continues to flow in, the liquid can flow out through the liquid guiding groove 133C of the liquid guiding part 133, so that there is enough liquid for the roller brush 120 to absorb at the position corresponding to the liquid guiding part 133, thereby realizing more comprehensive wetting of the roller brush 120 and helping to further improve the uniformity of water supply to the roller brush 120.

[0073] In some embodiments, referring to Figure 7 , the groove bottom wall of the liquid guiding groove 133C is arranged to be inclined relative to the liquid uniformizing table surface 132, and the end of the groove bottom wall of the liquid guiding groove 133C close to the liquid outlet 111 is higher than the liquid uniformizing table surface 132. By designing the end of the liquid guiding groove 133C close to the outlet to be higher than the liquid uniformizing table surface 132, the liquid flowing out of the liquid outlet 111 can be prevented from directly flowing out through the liquid guiding groove 133C of the liquid guiding part 133 without being guided to flow towards the liquid uniformizing table surface 132, thereby affecting the liquid uniformizing effect of the liquid uniformizing table surface 132. Instead, only when the liquid accumulation on the liquid uniformizing table surface 132 reaches the height of the liquid guiding groove 133C, the liquid can enter the liquid guiding groove 133C and flow out through the liquid guiding groove 133C.

[0074] In addition, the bottom wall of the liquid guide groove 133C is designed to be inclined, so that after the liquid flows into the liquid guide groove 133C, the liquid will flow naturally along the bottom wall of the liquid guide groove 133C to the direction of the roller brush 120 under the action of gravity, flow out of the liquid guide groove 133C, and soak the roller brush 120, thereby helping to improve the liquid guiding speed.

[0075] In some embodiments, with reference to Figure 1 and Figure 6 The shielding part 131 is provided with a scraping strip 131T, the scraping strip 131T is protruded from the side of the shielding part 131 away from the liquid outlet 111, the scraping strip 131T includes a first surface b1 and a second surface b2 connected to each other, and the included angle β between the first surface b1 and the second surface b2 is not greater than 120°; wherein the liquid uniformizing table surface 132 is arranged on the first surface b1. Exemplarily, the included angle β can be in the range of 60°-85°.

[0076] During the cleaning operation of the cleaning device 100, the roller brush 120 rotates to contact the scraping strip 131T, and since the liquid uniformizing table surface 132 is arranged on the first surface of the scraping strip 131T, when the liquid flows out of the liquid outlet 111 and is uniformly spread on the liquid uniformizing table surface 132, the roller brush 120 can uniformly absorb the liquid from the liquid uniformizing table surface 132. In addition, the included angle β between the first surface and the second surface of the scraping strip 131T is not greater than 120°, and the design of the included angle between the two connected surfaces of the scraping strip 131T enables the edge of the scraping strip 131T to effectively press the cloth, so as to accelerate the penetration and diffusion of the liquid in the cloth of the roller brush 120, thereby helping to improve the water uniformizing effect.
