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] In order to solve the technical problem that the existing water squeezing structure is prone to cause sewage on the drum to leak to the ground during the squeezing process, causing secondary pollution to the ground, the present invention provides a water squeezing structure, a cleaning component assembly and a cleaning robot, wherein a blocking portion is arranged on the bottom surface of the guide portion of the water squeezing structure, and the blocking portion forms a discontinuous plane structure to prevent water from flowing outward along the bottom surface of the guide portion, thereby guiding the water on the bottom surface of the guide portion to the sewage receiving portion below it, preventing the water on the bottom surface of the guide portion from flowing outward and falling to the ground, and further reducing water leakage during the squeezing process of the cleaning component.

[0044] The following will be combined with the attached Figures 1 to 13 The water squeezing structure, cleaning component assembly and cleaning robot provided in the embodiments of the present invention are described in detail.

[0045] See also Figures 1 to 6 , Figure 1 This is a schematic diagram of the cleaning robot.

Figure 5 It is a schematic diagram of the coordination between the squeezing structure and the sewage tank, where S1 and S2 represent the areas enclosed by the dotted lines in the figure. Figure 6 It is a structural schematic diagram of the water squeezing structure from another perspective.

[0046] The embodiment of the present invention provides a water squeezing structure 10, which includes an extruding portion 11 and a guide portion 12. The extruding portion 11 can cooperate with a cleaning member 20 to extrude the cleaning member 20. The guide portion 12 is connected to the extruding portion 11. A guide channel 120 and a water outlet 121 for guiding liquid to the outside are provided on the guide portion 12. One end of the guide channel 120 is connected to the extruding portion 11, and the other end is connected to the water outlet 121. Under the extrusion of the extruding portion 11, water on the cleaning member 20 can be squeezed out, flow into the guide channel 120 and flow out from the water outlet 121; a blocking portion 13 is provided on the bottom surface of the guide portion 12, and the blocking portion 13 forms a discontinuous plane structure to prevent water from flowing outward along the bottom surface of the guide portion 12.

[0047] The water squeezing structure 10 is applied to the cleaning equipment and is used to squeeze the cleaning parts 20 on the cleaning equipment. It can be understood that the cleaning equipment can be a floor cleaning equipment such as a cleaning robot 100 or a handheld floor scrubber, or a window cleaning equipment such as a window inserter. It is only necessary for the cleaning equipment to have the cleaning parts 20.

[0048] Depending on the type of cleaning equipment, the cleaning member 20 can clean the floor, walls, windows, etc. For example, in the cleaning robot 100, the cleaning member 20 is a roller, which is used to clean the floor. Optionally, the cleaning member 20 is made of a flexible material, for example, the cleaning member 20 is made of a nylon material, which has good water absorption and dehydration properties, so that it is easy to clean the sewage on the floor, and under the squeezing of the water squeezing structure 10, the water on the cleaning member 20 can be easily squeezed out.

[0049] like Figure 2 As shown, the cleaning device (here taking the cleaning robot 100 as an example) has a sewage receiving part 31. Optionally, the cleaning robot 100 includes a sewage tank 30, in which a sewage receiving part 31 is provided. Optionally, the sewage receiving part 31 is a sewage trough. The water squeezing structure 10 is arranged on one side of the cleaning member 20 and abuts against the cleaning member 20. The sewage receiving part 31 is arranged on the side of the water squeezing structure 10 away from the cleaning member 20 and is located below the water squeezing structure 10. After the water squeezing structure 10 squeezes the cleaning member 20, the sewage receiving part 31 is used to receive the sewage squeezed out from the cleaning member 20.

[0050] The water squeezing structure 10 is an elongated structure as a whole. The water squeezing structure 10 is roughly the same length as the cleaning member 20 and is arranged along the length direction of the cleaning member 20 to ensure that the cleaning member 20 can be evenly stressed when the cleaning member 20 is squeezed. The water squeezing structure 10 includes a squeezing portion 11 and a guide portion 12. Optionally, the squeezing portion 11 and the guide portion 12 are an integrally formed structure to improve their structural strength. After the water squeezing structure 10 is assembled and the cleaning member 20 is soaked in water, the squeezing portion 11 can abut against the wetted cleaning member 20. In this way, after the cleaning member 20 becomes dirty, the squeezing portion 11 can abut against the cleaning member 20 and squeeze the cleaning member 20 to squeeze out the sewage in the cleaning member 20. The guide portion 12 is arranged on the side of the extrusion portion 11 away from the cleaning member 20. The guide portion 12 is provided with a guide channel 120 and a water outlet 121. The guide channel 120 is used to receive the sewage squeezed out from the cleaning member 20. The water outlet 121 is connected to the guide channel 120, so that the sewage in the guide channel 120 is introduced into the sewage receiving portion 31 through the water outlet 121.

[0051] The bottom surface of the guide portion 12 is located above the sewage receiving portion 31. It can be understood that, since the squeezing structure 10 abuts against one side of the cleaning member 20, the distance between the bottom surface of the guide portion 12 and the cleaning member 20 is relatively close, and the distance between the sewage receiving portion 31 and the cleaning member 20 is relatively far. There is a gap between the sewage receiving portion 31 and the cleaning member 20. The edge of one side of the bottom surface of the guide portion 12 close to the cleaning member 20 is located on the outside of the sewage receiving portion 31, that is, the area where S1 is located (see FIG. Figure 5 ) corresponds to the outside of the sewage receiving portion 31. In addition, in some embodiments, the cleaning member 20 is usually as long as the body of the cleaning robot 100 to ensure the cleaning area of ​​the cleaning member 20, and the sewage receiving portion 31 is arranged inside the cleaning robot 100. The length of the sewage receiving portion 31 along the axial direction of the cleaning member 20 is usually less than the length of the cleaning member 20. Since the length of the guide portion 12 is substantially the same as the length of the cleaning member 20, the two end areas of the bottom surface of the guide portion 12 along the axial direction of the cleaning member 20 are also located outside the sewage receiving portion 31, that is, the area where S2 is located (see Figure 5 ) corresponds to the outer side of the sewage receiving part 31.

[0052] In this embodiment, the bottom surface 1200 of the guide portion 12 refers to the surface of the guide portion 12 facing downward in the vertical direction after the water squeezing structure 10 is installed on the cleaning robot 100, that is, the surface of the guide portion 12 facing the ground.

[0053] In this embodiment, the bottom surface 1200 of the guide portion 12 is a discontinuous plane structure, which is a non-planar structure. In other words, as long as it is a non-planar structure, it can be interpreted as a discontinuous plane structure. In other words, the bottom surface 1200 of the guide portion 12 cannot form a continuous plane along a certain direction, so that the water on the bottom surface 1200 of the guide portion 12 cannot always flow along the horizontal plane, and the water flow path will have ups and downs. Combined with the effect of gravity, the water will separate from the bottom surface 1200 of the guide portion 12 during the flow process, thereby achieving the purpose of blocking the flow.

[0054] It can be understood that a discontinuous plane can be interpreted as a number of structures of varying heights that are connected, or as a curved surface structure (a curved surface can be viewed as countless discontinuous planes), or as a concave-convex structure, etc.

[0055] It can be understood by those skilled in the art that, compared with a planar structure, a discontinuous planar structure helps to prevent the flow of water on the bottom surface 1200 of the guide portion 12 and guide the water into the sewage receiving portion 31. In other words, if the bottom surface 1200 of the guide portion 12 is a plane, under the influence of the Coanda effect (wall attachment effect), water will be adsorbed on the bottom surface 1200 of the guide portion 12 and spread along the bottom surface 1200 of the guide portion 12 to the S1 and S2 areas to cause water leakage.

[0056] In this embodiment, on the one hand, when the squeezing portion 11 squeezes the cleaning member 20, the sewage on the cleaning member 20 can be guided to the sewage receiving portion 31 through the guide channel 120 and the water outlet 121 in sequence, thereby reducing water leakage during the squeezing process of the cleaning member 20.

[0057] On the other hand, a blocking portion 13 is provided at the bottom of the guide portion 12, and the blocking portion 13 forms a discontinuous plane structure. The discontinuous plane structure can prevent the flow of water on the bottom surface of the guide portion 12, so that the water on the bottom surface of the guide portion 12 can quickly flow into the sewage receiving portion 31 thereunder, thereby preventing the water on the bottom surface of the guide portion 12 from flowing outward to the bottom edge area of ​​the guide portion 12 and dripping to the ground, further reducing the water on the bottom surface 1200 of the guide portion 12 from flowing outward to the S1 and S2 areas during the extrusion process of the cleaning member 20, thereby causing water leakage.

[0058] In other words, if the bottom surface of the guide portion 12 is not provided with a flow blocking portion 13 (that is, the bottom surface of the guide portion 12 is a plane), due to the existence of the Coanda effect (wall attachment effect), the water on the bottom surface of the guide portion 12 will flow outward along the bottom surface 1200 of the guide portion 12 to the areas where S1 and S2 are located, and directly drip onto the ground, thereby causing secondary contamination of the ground.

[0059] In some embodiments, the discontinuous plane structure may be one or more of a concave-convex structure, an eaves-like structure, a stepped plane structure, and a curved surface structure.

[0060] In some embodiments, the extrusion portion 11 includes an extrusion surface, which abuts against the outer surface of the cleaning member 20 and squeezes the cleaning member 20, thereby squeezing the sewage in the cleaning member 20 and introducing it into the diversion channel 120. Optionally, the extrusion surface and the groove wall of the diversion channel 120 are arranged to have a smooth transition to facilitate the drainage of the squeezed sewage into the diversion channel 120.

[0061] In some embodiments, the guide channel 120 is arranged on the side of the guide part 12 away from the bottom surface of the guide part 12 and is substantially the same length as the water squeezing member to increase the volume of the guide channel 120 and prevent sewage from overflowing from the guide channel 120 when the amount of water squeezed is large.

[0062] In some embodiments, the water outlet 121 is located on the side of the guide channel 120 away from the cleaning member 20, and the length of the water outlet 121 along the axial direction of the cleaning member 20 is less than the length of the guide channel 120 along the axial direction of the cleaning member 20.

[0063] In this embodiment, the water outlet 121 is located on the side of the guide portion 12 away from the extrusion portion 11, and the water outlet 121 is narrowed. The size of the water outlet 121 is designed to be relatively small, which helps to reduce the Coanda effect and prevent excessive sewage from flowing into the bottom surface of the guide portion 12. In other words, if the length of the water outlet 121 is designed to be too long, the Coanda effect will be more obvious, and more sewage will flow from the water outlet 121 to the bottom surface of the guide portion 12.

[0064] Optionally, the water outlet 121 is opened in the middle position of the guide portion 12, so that the distance from the water outlet 121 to the two ends of the length direction of the bottom surface of the guide portion 12 is farther, thereby reducing the sewage flowing out of the water outlet 121 and reaching the two ends of the length direction of the bottom surface of the guide portion 12, that is, avoiding sewage from flowing into the area where S2 is located.

[0065] Optionally, the bottom surface of the diversion channel 120 is inclined downward toward the middle along both ends, so as to facilitate rapid introduction of sewage in the diversion channel 120 into the water outlet 121 .

[0066] See also Figures 7 to 10 , Figure 7 is a schematic diagram of a partial structure of the water squeezing structure 10, Figure 8 This is a cross-sectional diagram of the assembled water squeezing structure, cleaning parts and sewage tank. Fig. 9 This is a schematic diagram of the local structure of the water squeezing structure from another perspective. Fig.10 FIG. 1 is a partial structural diagram of the water squeezing structure 10 from another perspective, wherein X represents the first direction and Y represents the second direction.

[0067] In some embodiments, the blocking portion 13 includes a first blocking portion 131, which corresponds to the position of the water outlet 121. The first blocking portion 131 has a concave-convex structure to prevent water on the first blocking portion 131 from flowing along a first direction, and the first direction is the direction of the water outlet 121 toward the extrusion portion 11.

[0068] like Fig.10 As shown, the first direction is indicated by the reference numeral X, and the first direction X is the width direction of the bottom surface 1200 of the guide portion 12. The first flow blocking portion 131 is located below the water outlet 121 and directly above the sewage receiving portion 31. The first flow blocking portion 131 is located at one end of the bottom surface 1200 of the guide portion 12 away from the extrusion portion 11. The first flow blocking portion 131 is arranged in a concave-convex shape along the width direction of the bottom surface of the guide portion 12. In this way, the sewage flowing out from the bottom of the water outlet 121 will first flow to the concave-convex first flow blocking portion 131. The first flow blocking portion 131 prevents the sewage from flowing along the first direction X, so that the sewage on the first flow blocking portion 131 can quickly drip into the sewage receiving portion 31 below it under the action of its own gravity, and the sewage on the first flow blocking portion 131 is prevented from flowing outward along the first direction to the S1 area and then dripping to the ground.

[0069] In some embodiments, the blocking portion 13 also includes a second blocking portion 132, which is located on a side of the first blocking portion 131 away from the water outlet 121, and the second blocking portion 132 has a concave-convex structure to prevent water on the first blocking portion and the second blocking portion from flowing along the first direction X.

[0070] The second flow blocking portion 132 is arranged in a concave-convex shape along the width direction of the bottom surface of the guide portion 12, and is located on the side of the first flow blocking portion 131 away from the water outlet 121. The area where the second flow blocking portion 132 is located covers the length direction of the bottom surface of the guide portion 12. The sewage flowing out from both sides of the water outlet 121 will first flow to the second flow blocking portion 132. The second flow blocking portion 132 prevents the sewage from continuing to flow along the first direction X, and then the sewage on the second flow blocking portion 132 can quickly fall into the sewage receiving portion 31 below it under the action of its own gravity, thereby preventing the sewage on the second flow blocking portion 132 from flowing outward along the length direction perpendicular to the water outlet 121 to the S1 area and then dripping to the ground.

[0071] In addition, after the sewage flowing into the first blocking part 131 from the bottom of the water outlet 121 is blocked by the first blocking part 131, it can also be blocked by the second blocking part 132. In other words, when the water flow rate is large, part of the sewage on the first blocking part 131 will flow along the first direction X to the second blocking part 132 and be blocked by the second blocking part 132, so that the blocking effect is further improved through the cooperation between the first blocking part 131 and the second blocking part 132, thereby avoiding water leakage during the process of squeezing the cleaning part 20 by the squeezing part 11.

[0072] In some embodiments, the first flow blocking portion 131 includes a first groove 1310 , and the second flow blocking portion 132 includes a second groove 1320 . The length directions of the first groove 1310 and the second groove 1320 are both parallel to the length direction of the water outlet 121 .

[0073] The first blocking portion 131 includes a first groove 1310, and the second blocking portion 132 includes a second groove 1320. When the sewage on the first blocking portion 131 flows toward the first groove 1310, and when the sewage on the second blocking portion 132 flows toward the second groove 1320, the first groove 1310 and the second groove 1320 can block the flow of sewage and reduce the adsorption of sewage on the bottom surface of the guide portion 12, so that the sewage can quickly fall into the sewage receiving portion 31.

[0074] Optionally, there can be multiple first grooves 1310 and second grooves 1320, and the first grooves 1310 and second grooves 1320 are respectively arranged along the length direction of the bottom surface of the guide part 12, so as to better prevent sewage from flowing along the width direction of the bottom surface of the guide part 12, thereby reducing sewage from falling to the ground.

[0075] In some embodiments, in the vertical direction, the blocking portion is arranged to be inclined downward along the two ends toward the middle direction, that is, the bottom surface 1200 of the guide portion 12 is arranged to be inclined downward along the two ends toward the middle direction. In other words, the horizontal positions of the two ends of the bottom surface 1200 of the guide portion 12 are relatively high, and the horizontal position of the middle part of the bottom surface of the guide portion 12 is relatively low. Therefore, it is possible to reduce the flow of water in the middle part of the bottom surface of the guide portion 12 to both sides, and divert the sewage at the two ends of the bottom surface 1200 of the guide portion 12 to the middle direction. In this way, it is possible to avoid excessive water accumulation at the two ends of the bottom surface 1200 of the guide portion 12 and dripping to the outside of the sewage receiving portion 31 and then dirtying the ground.

[0076] In some embodiments, the bottom surface of the second groove 1320 is tilted downward along both ends toward the middle to reduce excessive water accumulation at both ends of the bottom surface of the second groove 1320 and prevent water from dripping to the outside of the sewage receiving part 31 .

[0077] In some embodiments, the blocking portion 13 also includes a third blocking portion 133, and the length extension direction of the third blocking portion 133 is set at an angle to the length extension direction of the first blocking portion 131 and / or the second blocking portion 132 to prevent water on the first blocking portion 131 and / or the second blocking portion 132 from flowing along a second direction, and the second direction is perpendicular to the first direction X.

[0078] like Fig.10As shown, the reference numeral Y represents the second direction, and the second direction Y is the length direction of the bottom surface 1200 of the guide portion 12. The first blocking portion 131 and the second blocking portion 132 extend along the length direction of the bottom surface 1200 of the guide portion 12, and the third blocking portion 133 extends along the width direction of the bottom surface 1200 of the guide portion 12. The third blocking portion 133 and the first blocking portion 131 and the second blocking portion 132 are alternately arranged. The third blocking portion 133 blocks the water on the bottom surface 1200 of the guide portion 12 from flowing toward the S2 area along the second direction, so as to prevent excessive water accumulation in the S2 area and dripping to the outside of the sewage receiving portion 31.

[0079] In some embodiments, the third baffle 133 includes a plurality of partitions, which are perpendicular to the length extension direction of the second baffle 132, that is, the partitions are arranged parallel to the first direction X, and the second groove 1320 is divided into a plurality of sub-grooves by the plurality of partitions. This can better prevent the sewage on the second baffle 132 from flowing to the S2 area at both ends of the bottom surface 1200 of the guide part 12, especially prevent the sewage in the second groove 1320 from flowing to the S2 area.

[0080] It is understandable that, in other embodiments, the partition may also be arranged perpendicular to the extension direction of the first flow blocking portion 131 .

[0081] In some embodiments, the third blocking portion 133 and the first blocking portion 131 are staggered to form a grid structure; the first blocking portion 131 includes a plurality of first grooves 1310, and the third blocking portion 133 includes a plurality of partitions. The plurality of first grooves 1310 and the plurality of partitions are staggered to form a grid structure, and the partitions divide the first grooves 1310 into a plurality of smaller sub-grooves. In this way, each sub-groove has the function of blocking the flow of sewage, thereby achieving a better sewage blocking effect.

[0082] Similarly, the third flow blocking portion 133 and the second flow blocking portion 132 may also form a grid structure, which will not be described in detail herein.

[0083] In some embodiments, the guide portion 12 includes a guide body 122 and a protrusion 123, the guide channel 120 is opened on the guide body 122, the protrusion 123 is protruded on the side of the guide body 122 away from the extrusion portion 11, the water outlet 121 is opened on the protrusion 123, the first flow blocking portion 131 is arranged at the bottom of the protrusion 123, and the second flow blocking portion 132 is arranged at the bottom of the guide body 122.

[0084] The flow guide portion 12 includes a flow guide body 122 and a protruding portion 123 , and the flow guide body 122 and the protruding portion 123 are an integrally formed structure.

[0085] The protrusion 123 is protruding from the side of the guide body 122 away from the extrusion portion 11, that is, the protrusion 123 is arranged on the side of the guide body 122 close to the sewage receiving portion 31, and the water outlet 121 and the first flow blocking portion 131 are respectively arranged on the protrusion 123, so that the water outlet 121 and the first flow blocking portion 131 are closer to the sewage receiving portion 31, thereby reducing the possibility that sewage drips to the outside of the sewage receiving portion 31 and causes the ground to be dirty during the process of the extrusion portion 11 squeezing the cleaning member 20.

[0086] In addition, since the first flow blocking portion 131 is arranged on the bottom surface of the protrusion 123, the first flow blocking portion 131 no longer occupies the area of ​​the bottom surface of the flow guide body 122, so that there is enough space on the bottom surface of the flow guide body 122 to set the second flow blocking portion 132, which helps to design the second flow blocking portion 132 to be wider, thereby improving the flow blocking effect of the second flow blocking portion 132 and reducing the amount of sewage falling to the ground.
