The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] Please also read Figure 1 , Figure 2 and Figure 3 , Figure 1 It is a schematic diagram of the cooperation structure of the water squeezing component 100 and the mopping component 200 provided in one embodiment of the present invention; Figure 2 yes Figure 1 Schematic diagram of the exploded structure of the water squeezing part 100 and the mopping part 200; Figure 3 yes Figure 1 Schematic diagram of the overall structure of the middle water squeezing member 100.

[0044] An embodiment of the present invention provides a water squeezing member 100, comprising an extruding portion 10, which can cooperate with a mop member 200 to extrude the mop member 200, and the extruding portion 10 comprises an extruding surface 11, which abuts against the outer surface of the mop member 200; a guide portion 20, which is connected to the extruding portion 10 and enclosed with the extruding portion 10 to form a water collecting trough 30; in the vertical direction, the extruding portion 10 also comprises a guide surface 12, which is connected between the extruding surface 11 and the groove wall of the water collecting trough 30; the guide surface 12 is arranged to be inclined downward toward the middle along both sides.

[0045] Among them, the water squeezing part 100 is used in the cleaning equipment and is used to squeeze the mop part 200 on the cleaning equipment. It can be understood that the cleaning equipment can be a floor cleaning equipment such as a cleaning robot 400 or a handheld floor scrubber, or a window cleaning equipment such as a window cleaning machine. It only needs to have a rotating mop part 200 for cleaning.

[0046] Depending on the type of cleaning equipment, the mop piece 200 can be used to clean the floor, walls, windows, etc. For example, in the cleaning robot 400, the mop piece 200 adopts a mop. Optionally, the mop is made of a flexible material, for example, the mop is made of a fiber material, and the fiber material has good water absorption and dehydration properties. The mop piece 200 absorbs dirt on the floor during mopping cleaning, and then the mop piece 200 is moistened with clean water. Finally, the water squeezing piece 100 squeezes the mop piece 200 to squeeze out the dirty water from the mop piece 200, so that the mop piece 200 can effectively clean for a long time.

[0047] In one embodiment, the mop member 200 is substantially in the shape of a drum, and the mop member 200 is sleeved on the drum. The drum is externally connected to a driving device so that the drum obtains a power source to rotate. It can be understood that the mop member 200 rotates by the rotation of the drum.

[0048] Specifically, the mop member 200 rotates, and relative movement occurs between the extrusion portion 10 and the mop member 200. Moreover, the extrusion surface 11 is directly opposite to the mop member 200, and the extrusion surface 11 can squeeze the mop member 200 to squeeze out the sewage on the mop member 200, and the sewage on the mop member 200 flows from both sides to the middle through the surface of the guide surface 12, and flows into the water collection tank 30 after being collected in the middle of the guide surface 12.

[0049] Specifically, during the process of being squeezed out, the sewage will be retained on the outer edge of the extrusion part 10. Moreover, the guide surface 12 is the outer edge of the top wall of the extrusion part 10 close to the mop part 200. When the sewage adheres to the guide surface 12, the Coanda effect (i.e., the wall attachment effect, when the curvature of the surface of the object is not large, the fluid will flow along the surface of the object) will occur. At the same time, a V-shaped notch will be formed on the outer edge of the extrusion part 10. Optionally, a U-shaped notch will be formed on the outer edge of the extrusion part 10. Since the sewage attached to the guide surface 12 will move along the surface of the guide surface 12, and under the influence of gravity, the sewage will be concentrated from both sides of the guide surface 12 to the middle direction, and then flow into the sump 30. This reduces the situation where the sewage adheres to the edge of the extrusion part 10 and drips on the ground, achieving a good cleaning effect.

[0050] In addition, the guide surface 12 is an inclined plane or a curved surface, and the contact area between the guide surface 12 and the mop member 200 is larger relative to the horizontal plane, so more sewage is squeezed out per unit time, and the sewage discharge efficiency is higher.

[0051] Reference Figure 3 and Figure 4 , Figure 4 yes Figure 1 Schematic diagram of the top view of the water squeezing component 100 and the mopping component 200.

[0052] In one embodiment, the pressing surface 11 presses against the mop member 200 to press the surface of the mop member 200 so that the dirty water in the mop member 200 is squeezed out; the pressing surface 11 gradually moves away from the axis of the rotating shaft of the mop member 200 from top to bottom.

[0053] Specifically, the extrusion surface 11 gradually moves away from the axis of the rotation shaft of the mop member 200 from top to bottom (refer to Figure 3 and Figure 4 ), the extrusion surface 11 is pressed against the mop piece 200, the extrusion surface 11 is a V-shaped surface, and the outer surface area on both sides of the extrusion surface 11 is larger than the outer surface area in the middle of the extrusion surface 11, so that the extrusion force of the extrusion surface 11 on both sides of the mop piece 200 is larger than the extrusion force of the extrusion surface 11 on the middle of the mop piece 200, thereby facilitating the extrusion of the sewage on both sides of the mop piece 200 to the middle of the mop piece 200, and the sewage then flows into the sump 30 through the surface of the guide surface 12.

[0054] Optionally, the extrusion surface 11 is an inclined slope.

[0055] Optionally, the extrusion surface 11 is an arc-shaped curved surface, which further increases the contact area between the extrusion surface 11 and the mop member 200 .

[0056] Reference Figure 3 and Figure 5 , Figure 5 yes Figure 1 Schematic diagram of the cross-sectional structure of the water squeezing component 100 and the mopping component 200.

[0057] In one embodiment, the extrusion surface 11 has an arc, and the center of curvature of the extrusion surface 11 is located on the axis of the rotation shaft of the mop member 200; or the center of curvature of the extrusion surface 11 is located on the side of the axis of the rotation shaft of the mop member 200 away from the extrusion portion 10; the center of curvature of the extrusion surface 11 is located on the side of the axis of the rotation shaft of the mop member 200 close to the extrusion portion 10.

[0058] Specifically, the mop member 200 is roughly cylindrical, and the extrusion surface 11 has an arc; when the center of curvature of the extrusion surface 11 is located on the axis of the rotating shaft of the mop member 200, the extrusion surface 11 is more closely fitted to the outer surface of the mop member 200. On the one hand, the extrusion force of the extrusion surface 11 on both sides of the mop member 200 is greater than the extrusion force of the extrusion surface 11 on the middle of the mop member 200, which promotes the sewage on both sides of the mop member 200 to be squeezed to the middle of the mop member 200. On the other hand, the friction between the mop member 200 and the extrusion surface 11 is reduced, so that the mop member 200 rotates more smoothly. In addition, the contact area between the extrusion surface 11 and the outer surface of the mop member 200 can be increased, and the cleaning effect of the mop member 200 can be improved per unit time.

[0059] Optionally, the center of curvature of the extrusion surface 11 is located on a side of the rotation axis of the mop member 200 away from the extrusion portion 10 .

[0060] Optionally, the center of curvature of the extrusion surface 11 is located on a side of the rotation axis of the mop member 200 close to the extrusion portion 10 .

[0061] Reference Figure 3 In one embodiment, the diversion portion 20 is provided with a diversion port 21 , which is connected to the water collecting tank 30 , and the opening of the diversion port 21 faces the side away from the extrusion portion 10 , and the sewage is discharged through the diversion port 21 after being collected in the water collecting tank 30 .

[0062] Specifically, the sewage collected in the water collection tank 30 can be discharged through the diversion port 21, thereby preventing the sewage in the water collection tank 30 from being full and overflowing.

[0063] Reference Figure 5 and Figure 6 , Figure 6 yes Figure 5Schematic diagram of the bottom structure of the middle water squeezing member 100.

[0064] In one embodiment, a water blocking portion 40 is provided on the bottom surface of the guide portion 20 near the guide port 21 , and the water blocking portion 40 forms a discontinuous planar structure to prevent sewage from flowing out along the bottom surface of the extrusion portion 10 .

[0065] Specifically, the Coanda effect may occur when the sewage passes through the diversion port 21, that is, the sewage may flow along the bottom wall of the diversion portion 20 toward the extrusion portion 10. The water blocking portion 40 is provided to prevent the sewage from flowing from the bottom wall of the diversion portion 20 toward the extrusion portion 10.

[0066] Reference Figure 5 and Figure 6 In one embodiment, the water blocking portion 40 corresponds to the position of the guide port 21 , and the water blocking portion 40 has a concave-convex structure to prevent the sewage on the water blocking portion 40 from flowing along the water blocking portion 40 toward the extrusion portion 10 .

[0067] Specifically, the water blocking portion 40 is integrally manufactured with the flow guide portion 20. The water blocking portion 40 has a concave-convex structure that can increase the plane curvature in the sewage flow path. Because the Coanda effect is that when the curvature of the surface of an object is not large, the fluid flows along the surface of the object; therefore, the setting of the water blocking portion 40 increases the curvature of the bottom surface of the flow guide portion 20, making it difficult for sewage to adhere to the water blocking portion 40, so as to prevent the sewage from moving along the bottom surface of the extrusion portion 10 toward the extrusion portion 10.

[0068] Reference Figure 5 , Figure 6 and Figure 7 , Figure 7 yes Figure 5 Schematic diagram of the cross-sectional structure of the water squeezing part.

[0069] In one embodiment, the water blocking portion 40 includes a water blocking strip 41 , and the cross-sectional area of ​​the water blocking strip 41 gradually decreases in a direction away from the flow guiding portion 20 .

[0070] Specifically, the water blocking strip 41 is roughly a semi-cylinder, and the portion of the water blocking strip 41 protruding from the bottom surface of the guide portion 20 is roughly semicircular. When the sewage passes through the water blocking strip 41, the area of ​​the bottom of the water blocking strip 41 is very small, and due to the sewage's own gravity, it is difficult for the sewage to adhere to the bottom of the water blocking strip 41.

[0071] Optionally, by providing a plurality of water blocking strips 41 , the plurality of water blocking strips 41 are spaced apart to further prevent sewage from flowing toward the squeezing portion 10 .

[0072] Optionally, the water blocking strip 41 may be a strip with a tapered cross section.

[0073] Optionally, the water blocking strip 41 may be a strip with a triangular cross section.

[0074] Reference Figure 5 and Figure 7 In one embodiment, a plurality of water-blocking strips 41 are provided, and the plurality of water-blocking strips 41 are sequentially spaced apart along the bottom of the guide portion 20 , and a water-blocking surface 42 is provided between any two adjacent water-blocking strips 41 , and the water-blocking surface 42 is provided obliquely downwardly along both sides of the bottom of the guide portion 20 to the middle.

[0075] Specifically, in one embodiment, three water blocking strips 41 are provided, and the three water blocking strips 41 are all located at the bottom of the flow guide 20, and the three water blocking strips 41 are evenly spaced and distributed along the direction from the flow guide to the extrusion portion 10. A water blocking surface 42 is provided between any two adjacent water blocking strips 41, and the water blocking surface 42 is connected to the outer surfaces of the two water blocking strips 41, and the water blocking surface 42 is an inclined surface arranged downward along the two sides to the middle of the bottom of the flow guide 20; the purpose is that when the sewage passes through the first water blocking strip 41, the sewage may move along the two sides of the water blocking surface 42 and overflow; the outer surface of the water blocking surface 42 is arranged downward along the two sides to the middle, so that after the sewage passes through the first water blocking strip 41, the sewage will be concentrated at the lowest part of the water blocking surface 42 and drip, so as to avoid the sewage overflowing from both sides.

[0076] For ease of understanding, refer to Figure 6 The cleaning surface reference surface 43 is also included. It can be understood that the cleaning surface reference surface 43 refers to the parallel surface of the cleaning plane when the cleaning robot 400 is cleaning the plane.

[0077] Optionally, the water blocking surface 42 is a curved surface, and the center of curvature of the water blocking surface 42 is located on a side away from the bottom of the guide portion.

[0078] Reference Figure 3 and Figure 5 In one embodiment, the inner surface of the water extruding member 100 is inclined downward from both sides toward the middle.

[0079] Specifically, the inner surface of the water squeezing member 100 is inclined downward from both sides to the middle. On the one hand, this increases the volume of the water collecting tank 30 to prevent sewage from overflowing. On the other hand, sewage is collected in the middle of the water collecting tank 30 to prevent the cleaning robot 400 from bumping during movement and causing sewage to overflow from both sides of the water collecting tank 30.

[0080] Reference Figure 3 and Figure 5 In one embodiment, the water collecting trough 30 includes a water collecting surface 31, which is arranged on the inner wall of the water collecting trough 30 close to the extrusion portion 10, and the water collecting surface 31 has an arc, and the center of curvature of the water collecting surface 31 is located on the side of the water collecting trough 30 facing the guide portion 20.

[0081] Specifically, the water collecting surface 31 has a guiding effect, so that the water collecting tank 30 is a concave arc groove relative to the guide portion 20, so as to promote the sewage to flow toward the guide port 21, and avoid the sewage being enriched in the water collecting tank 30 and unable to be discharged.

[0082] In summary, taking the cleaning device as an example, when the cleaning device is cleaning dirt, the mop member 200 rotates so that the outer surface of the mop member 200 adheres to the dirt on the ground to achieve the effect of cleaning the ground. The water squeezing member 100 squeezes the wet outer surface of the mop member 200 so that the dirt on the outer surface of the mop member 200 is discharged in the form of sewage. Among them, the squeezing on both sides of the mop member 200 is greater than the squeezing on the middle of the mop member 200, thereby prompting the sewage on the mop member 200 to gather toward the middle of the mop member 200, reducing the sewage from the two sides of the mop member 200. In addition, the water squeezing member 100 is provided with a guide surface 12, and the guide surface 12 is arranged downwardly along both sides toward the middle, so that the sewage is gathered along the surface of the guide surface 12 and then enters the water collection tank 30, preventing the sewage from leaking along the two sides of the guide surface 12.

[0083] The Coanda effect occurs when sewage is discharged from the sump 30 . The water blocking portion 40 is provided at the bottom of the guide portion 20 to form a discontinuous plane structure to reduce the Coanda effect and prevent sewage from moving from the water blocking portion 40 to the extrusion portion 10 .

[0084] In addition, in order to reduce the interference of the guide part 20 on the mop member 200 during the rotation process, the extrusion surface 11 on the extrusion part 10 is set as a curved surface, and the center of curvature of the extrusion surface 11 is located on the axis of the rotation shaft of the mop member 200 .

[0087] Specifically, the cleaning device 300 can be applied to cleaning equipment, and can also be used independently as a cleaning device; it is understandable that the cleaning device 300 can be a flat cleaning device such as an automatic cleaning robot 400 or a hand-push cleaning machine.

[0088] The outer shell 310 is provided with a driving device, and the roller assembly 320 is externally connected to the driving device. Optionally, the driving device may be a driving motor, so that the roller component 321 rotates from top to bottom relative to the outer shell 310 .

[0089] Moreover, in one embodiment, the housing member 310 is substantially disc-shaped, so that it is not easy to collide with the wall when cleaning corners.

[0090] Optionally, the outer shell 310 may be in a major arc shape or a minor arc shape. It is understood that a major arc refers to an arc that is larger than a semicircle, and an arc that is smaller than a semicircle is a minor arc; so that the cleaning device 300 is easy to turn during the cleaning process.

[0091] Reference Fig.11 , Fig.12 and Fig.13 , Fig.11 yes Fig.10 A schematic diagram of the matching structure of the middle drum assembly 320 and the water leveling member 330; Fig.12 yes Fig.11 A schematic diagram of the specific structure of the middle water distribution member 330; Fig.13 yes Fig.12 A schematic structural diagram of the middle water distribution member 330 from another angle.

[0092] In one embodiment, the cleaning device 300 further includes a water uniforming member 330, which is connected to the outer shell member 310. In the rotation direction of the mop member 200, the water uniforming member 330 is located on the front side of the extrusion portion 10, and one side of the water uniforming member 330 is against the outer surface of the mop member 200. The length of the water uniforming member 330 is consistent with the length of the mop member 200, so that the water on the outer surface of the mop member 200 is pressed by the water uniforming member 330 and evenly adheres to the outer surface of the mop member 200.

[0093] Specifically, during the cleaning process of the mop member 200, different amounts of water will adhere to the surface of different areas of the mop member 200, where it can be understood that the water can be supplied to the outer surface of the mop member 200 by an external water pipe; or it can be ground stains or sewage, etc. The water-distributing member 330 abuts against the outer surface of the mop member 200 so that the water attached to the mop member 200 is squeezed out during the rotation of the mop member 200, and the water will be retained at the edge of the mop member 200 and the water-distributing member 330 until the water enters the area on the surface of the mop member 200 where no water is attached. Moreover, the length of the water-distributing member 330 is consistent with the length of the mop member 200, so that the water evenly covers the outer surface of the mop member 200. If the water is clean water, the cleaning ability of the mop member 200 can be improved to avoid the situation where some areas of the mop member 200 are not soaked and the ground stains cannot be removed.

[0094] Optionally, the water-distributing member 330 and the outer shell 310 are manufactured in one piece, wherein the water-distributing member 330 can be manufactured using different plastic materials through a rubber encapsulation process.

[0095] Optionally, the water leveling member 330 may be made of nylon hydrophobic material;

[0096] Optionally, the water leveling member 330 may be made of a plastic hydrophobic material.

[0097] In one embodiment, the water uniforming member 330 includes a baffle 332 and a water uniforming plate 331. The water uniforming plate 331 is connected to the outer shell member 310, and the water uniforming plate 331 is arranged obliquely downward relative to the outer shell member 310; the baffle 332 is connected to the water uniforming plate 331, and the baffle 332 abuts against the outer surface of the mop member 200. Two baffles 332 are provided, and the two baffles 332 are respectively located on the edge positions of both sides of the mop member 200; the two baffles 332 and the water uniforming plate 331 enclose a water retaining area 3321 to prevent water from flowing out from both sides of the water uniforming plate 331.

[0098] Specifically, during the rotation of the mop member 200, the water attached to the mop member 200 will be discharged and retained at the bottom edge of the water leveling plate 331. The water retained at the bottom of the water leveling plate 331 will experience the Coanda effect, that is, this part of the water will flow out along the two sides of the water leveling plate 331. By providing two baffles 332, the two baffles 332 and the water leveling plate 331 are enclosed to form a water retaining area 3321 to prevent water from flowing out from the two sides of the water leveling plate 331.

[0099] In one embodiment, the water-distributing plate 331 is roughly plate-shaped, and the water-distributing plate 331 and the baffle plate 332 are manufactured in one piece, thereby reducing the process assembly cost and also reducing the splicing gaps that cause water to flow out of the gaps.

[0100] Moreover, the baffle 332 is disposed close to the outer surface of the mop member 200 and fits the outer surface of the mop member 200 to reduce the gap between the baffle 332 and the mop member 200 and prevent water from flowing out of the gap.

[0101] Optionally, in the rotation direction of the mop member 200 , the baffle plate 332 is disposed on the front side of the water uniforming plate 331 .

[0102] Optionally, in the rotation direction of the mop member 200 , part of the baffle plate 332 is disposed on the front side of the water evenly distributing plate 331 , and another part of the baffle plate 332 is disposed on the rear side of the water evenly distributing plate 331 .

[0103] Optionally, the baffle plate 332 is vertically arranged relative to the inclination angle of the water-distributing plate 331 , so that the water-retaining area 3321 is suitable for mopping pieces 200 of different sizes.

[0104] Reference Fig.10 and Fig.11 In one embodiment, the cleaning device 300 further includes a water supply member 340, which is connected to the outer shell member 310. The water supply member 340 is used to provide clean water to the water uniforming member 330. The water uniforming member 330 includes a water guide plate 333, which is connected to the outer shell member 310. The water guide plate 333 is provided with a water guide hole 3331. The opening of the water guide hole 3331 is directly opposite to the mop member 200, so that the clean water of the water supply member 340 can adhere to the mop member 200 through the water guide hole 3331.

[0105] Specifically, the water supply member 340 is an external water pipe and a water tank, and the water guide plate 333 is connected to the water uniforming plate 331. Clean water flows into the surface of the mop member 200 through the water guide hole 3331. The water supply member 340 can provide clean water to give the mop member 200 a better cleaning ability. The length of the water guide plate 333 is consistent with the length of the mop member 200, so that the mop member 200 can be better soaked in clean water. In the rotation direction of the mop member 200, the water guide plate 333 is located in front of the water uniforming plate 331 to reduce the occurrence of dripping of the mop member 200 after the water is uniformly distributed.

[0106] Moreover, the two baffles 332 are connected to the water guide plate 333 to prevent the clean water from overflowing from both sides of the mop member 200. The water distribution plate 331, the baffle 332 and the water guide plate 333 are integrally manufactured, and the water guide plate 333 is connected between the water distribution plate 331 and the housing member 310.

[0107] In addition, the water uniforming plate 331 is placed obliquely relative to the water guide plate 333, and the water guide plate 333 is placed parallel to the cleaning plane, so that the distance between the water guide plate 333 and the mop piece 200 is equal everywhere, so that the surface of the mop piece 200 can be better immersed in water.

[0108] Optionally, a plurality of water guide holes 3331 are provided, and the plurality of water guide holes 3331 are evenly spaced and distributed along the length direction of the water guide plate 333 .

[0109] Reference Fig. 9 and Fig.14 , Fig.14 yes Fig. 9 Schematic diagram of the exploded view of the matching structure between the middle water squeezing member 100 and the collecting member 350.

[0110] In one embodiment, the cleaning device 300 further includes a collecting member 350 , which is detachably connected to the outer shell 310 . The collecting member 350 is provided with a sewage trough 351 , which is disposed below the sump 30 . The sewage is collected through the sump 30 and then flows into the sewage trough 351 .

[0111] Specifically, the collecting member 350 is detachably connected to the outer shell 310 so that when the sewage in the sewage tank 351 is full, the sewage in the sewage tank 351 can be processed at one time by removing the collecting member 350. Moreover, when the sewage tank 351 is arranged below the water collecting tank 30, the sewage passing through the diversion port 21 will form a Coanda effect, that is, it will flow along the bottom of the diversion part 20 and drip under the influence of the water blocking strip 41, and the dripping sewage will drip into the sewage tank 351 to prevent the sewage from overflowing on the ground and causing secondary pollution.

[0112] The housing member 310 includes a housing body 312 and a housing chassis 313. The mounting cavity 311 is provided on the housing body 312. The collecting member 350 is roughly in the shape of a semicircular box, and mounting grooves are provided on both sides of the arc edge of the collecting member 350. The housing chassis 313 is connected to the housing body 312. The housing chassis 313 is also roughly in the shape of a semicircular box. The housing chassis 313 includes a protrusion, and two protrusions are provided. The two protrusions are provided on the inner surfaces of both sides of the arc edge of the housing chassis 313. The two protrusions are relatively extended and arranged. The protrusions are accommodated in the mounting grooves, so that the collecting member 350 is clamped on the housing chassis 313. The purpose is that when the sewage in the sewage tank 351 is fully collected, the sewage in the sewage tank 351 can be processed at one time by disassembling the collecting member 350.

[0113] In one embodiment, the housing body 312 is connected to a housing chassis 313 , and the housing chassis 313 can be installed with a driving wheel structure so that the cleaning device 300 can move on a plane, and the housing chassis 313 can be produced as a separate chassis structure.

[0114] Optionally, the collecting member 350 may be detachably connected to the housing body 312 by screws.

[0115] Optionally, a corresponding sensor, such as a gravity sensor, is provided on the collecting member 350. When the sewage in the sewage tank 351 reaches a specified weight, a feedback signal is sent back to prompt the control panel to stop the rotation of the roller member 321. Another example is a laser sensor. The laser sensor irradiates the upper surface of the sewage tank 351 and sends back a signal. When the sewage in the sewage tank 351 exceeds a specified water level, a feedback signal is sent back to the control panel, and the control panel sends a signal to stop the rotation of the roller member 321.

[0116] In one embodiment, the sewage trough 351 includes a guide portion 3511 and a collecting portion 3512 , the collecting portion 3512 is connected between the two guide portions 3511 , and the guide portion 3511 is gradually inclined downward along the direction from the guide portion 3511 to the collecting portion 3512 toward the outer wall of the sewage trough 351 .

[0117] Specifically, the guide part 3511 and the collecting part 3512 are integrally manufactured, and the outer wall surfaces of the two guide parts 3511 and the collecting part 3512 form the groove wall of the sewage groove 351. After the sewage enters the sewage groove 351, the sewage will gather in the collecting part 3512. Because the cleaning device 300 will bump due to the uneven ground during the cleaning process, the sewage in the sewage groove 351 will gather in the middle to prevent the sewage in the sewage groove 351 from leaking on both sides of the sewage groove 351 due to the bump.

[0118] In summary, when the cleaning device 300 is cleaning the mop member 200, the roller member 321 receives the driving force of the driving motor and rotates in the upward and downward direction relative to the housing body 312, and the rolling member drives the mop member 200 to rotate. The water supply member 340 provides clean water, which flows to the outer surface of the mop member 200, and then adheres to the surface of the mop member 200 through the water guide plate 333, and then adheres to the outer surface of the mop member 200 evenly through the water uniforming plate 331. In addition, when the clean water adheres to the surface of the mop member 200, the baffle 332 is provided to prevent the clean water from flowing toward the two ends of the roller member 321.

[0119] When the surface of the mop member 200 is soaked, the mop member 200 rotates and is squeezed by the squeezing member 100, so that the dirty water formed by the stains and clean water on the outer surface of the mop member 200 is squeezed out, and the dirty water adheres to the outer edge of the squeezing member 100. At this time, the dirty water will have a Coanda effect, and the dirty water will move along the outer surface of the squeezing member 100. At the same time, the dirty water is guided by the guide surface 12 formed by the V-shaped notch of the squeezing member 100, so that the dirty water moves from both sides of the squeezing member 100 to the middle and is enriched, and the enriched dirty water will enter the water collection tank 30.

[0120] The walls of the water collecting tank 30 are also inclined from both sides toward the middle, and a guide port 21 is provided on the mounting plate, so that the sewage enriched in the water collecting tank 30 will pass through the guide port 21 .

[0121] The sewage passing through the diversion port 21 will partially flow along the side wall of the diversion port 21, that is, the sewage will flow along the bottom of the diversion portion 20, and this part of the sewage will move to the bottom of the mounting plate and be blocked by the water blocking strip 41, thereby dripping. Since the sewage tank 351 is arranged below the water blocking strip 41, the sewage on the water blocking strip 41 will eventually be collected by the sewage tank 351.

[0122] Another part of the sewage passing through the diversion port 21 will directly fall into the sewage tank 351, completing the collection of the sewage.

[0123] After the sewage is enriched in the sewage tank 351, the collecting component 350 can be disassembled to pour out the sewage, and the outer wall of the sewage tank 351 can be cleaned before installing the collecting component 350 again.

[0124] The present invention further provides a cleaning robot 400, comprising the above-mentioned cleaning device 300 and a robot body, wherein the cleaning device 300 is installed on the robot body.

[0125] It is understandable that the cleaning robot 400 has any one of the cleaning devices 300 and the water squeezing member 100 described above, so the cleaning robot 400 also has the advantages described above, which will not be elaborated herein.

[0126] Optionally, the cleaning robot 400 may be a household cleaning machine for cleaning floors, or a window cleaning machine for cleaning window glass, etc.
