[0092] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0093] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0094] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0095] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0096] The specific types of the cleaning robot 10 provided by the embodiments of this application include, but are not limited to, mopping robots, floor washing robots, integrated washing and mopping robots, sweeping and mopping integrated robots, or sweeping and washing integrated robots, etc. Among them, the cleaning robot 10 may include a cleaning member 11, and the floor washing cleaning member 11 or mopping cleaning member 11 on the cleaning robot 10 includes, but is not limited to, a rotary brush or a mop. More specifically, the cleaning member 11 may include one or a combination of two or more of a rotary brush, a fluff roller, a tracked mop, a flat mop, and a rotary disk mop.

[0097] In some embodiments, taking the cleaning robot 10 selected as an indoor mopping or floor washing cleaning robot 10 as an example for illustration. During the working process of the cleaning robot 10, while the cleaning robot 10 travels along the traveling direction, the cleaning member 11 thereon rotates or moves relative to the ground to clean the surface to be cleaned 30. For example, the rotary brush can rotate relative to the surface to be cleaned 30 and the main body, and the mop can contact the surface to be cleaned 30 through the cleaning surface and move along the surface to be cleaned 30 to achieve cleaning.

[0098] As Figure 1 shown, the cleaning robot 10 can travel forward during walking through various combinations of movements along the following three mutually perpendicular axes defined relative to its center: the front-rear axis X, the lateral axis Y, and the central vertical axis Z. The forward driving direction along the front-rear axis X is marked as "forward", and the backward driving direction along the front-rear axis X is marked as "backward". The direction of the lateral axis Y is substantially the direction extending between the right wheel and the left wheel of the device along the axis defined by the center point of the driving wheels of the cleaning robot 10. The cleaning robot 10 can rotate around the Y axis. When the front part of the cleaning robot 10 tilts upward and the rear part tilts downward, it is "upward tilt", and when the front part of the cleaning robot 10 tilts downward and the rear part tilts upward, it is "downward tilt". In addition, the cleaning robot 10 can rotate around the Z axis. In the forward direction of the cleaning robot 10, when the cleaning robot 10 tilts to the right side of the X axis, it is "right turn", and when the cleaning robot 10 tilts to the left side of the X axis, it is "left turn". The automatic obstacle avoidance function of the cleaning robot 10 includes, but is not limited to, stopping traveling, backing in the reverse direction, turning right, or turning left.

In the turning part 1522a, the direction of the suction force and the direction of the sewage are separated. Among them, Figure 4 the direction c described in is the direction in which the clear water channel 1522d in the sewage tank 15 sprays clear water towards the cavity wall of the sewage tank 15 through the spray water channel 1522f to clean the sewage tank 15. Among them, Figure 5 the direction d described in is the rotation direction of the cleaning part 11, Figure 5 the direction g described in is the direction in which the clear water in the clear water tank is supplied to the cleaning part 11 through the water outlet. Among them, Figure 6 the direction e described in is the direction in which the suction force enters the air passing cavity 1525 from the air inlet 1522c and exits from the air outlet 1521a. Among them, Figure 8 the direction e described in is the whole process direction in which the suction force of the suction fan 21 is separated from the sewage direction after being turned by the turning part 1522a, and the suction force enters the air passing cavity 1525 from the air inlet 1522c and exits from the air outlet 1521a. Among them, Figure 9 the direction e described in is the direction in which the suction force of the suction fan 21 is sucked out of the air outlet 1521a and enters the suction fan 21.

[0101] It should be noted that the media involved in this application include clean water, sewage, and suction wind force. Among them, the sewage is represented by direction b, the suction wind force is represented by direction e, and the overlapping direction of the sewage and the suction wind force is represented by direction a. There are two types of clean water. One is the clean water supplied to the clean water channel 1522d through the host clean water connection port 192, the clean water pipeline 18, the clean water transfer channel 162, and the clean water port 1515, which is represented by direction f, for the clean water used to self-clean the sewage tank 15. The other is the clean water supplied to the clean water tank in the cleaning robot 10 through the host clean water connection port 192 and supplied from the clean water tank to the cleaning member 11, which is represented by direction g.

[0102] Please refer to Figures 2 to 9 As shown, the cleaning robot 10 provided by the embodiment of this application includes a cleaning member 11, a sewage suction channel 14, a sewage tank 15, a host sewage connection port 191, and a suction fan 21. The cleaning member 11 is used for cleaning the surface to be cleaned or self-cleaning to generate sewage. The sewage suction channel 14 is at least connected to the surface of the cleaning member 11 and the sewage tank 15. The suction fan 21 is connected to the sewage tank 15 and is used for sucking at least the sewage generated on the surface of the cleaning member 11 into the sewage tank 15. The sewage tank 15 is connected to the host sewage connection port 191, and the host sewage connection port 191 is used for docking and connecting to the base station sewage connection port 22 to discharge the sewage in the sewage tank 15 to the base station.

[0103] Among them, the cleaning member 11 can be detachably assembled through the mounting member 12. For example, it can be manually assembled or disassembled. As Figures 26 to 28 shown, it is a schematic diagram of the cleaning member 11 and the mounting member 12 in a disassembled state, and schematic diagrams of the overall disassembled state and the assembled state after disassembly.

[0104] The cleaning member 11 can be arranged on the front side or the rear side of the cleaning robot 10 along the traveling direction. The cleaning member 11 has an axis, which can refer to the central axis of the cleaning member 11. The central axis is perpendicular to the traveling direction of the cleaning robot 10 or forms other angles. In the embodiment of this application, the cleaning member 11 is detachably assembled on the rear side of the cleaning robot 10 along the traveling direction, and the axis of the cleaning group is perpendicular to the traveling direction.

[0105] In some embodiments, the cleaning member 11 is preferably a mopping and washing member, and the mopping and washing member is preferably a roller brush. The roller brush has a circumferential surface provided around its rotation axis, and bristles covering the circumferential surface are provided on the circumferential surface. In the embodiment of this application, the cleaning member 11 is arranged on the rearmost side in the traveling direction, that is, compared with other cleaning members 11, the roller brush is arranged within the edge on the rear side in the traveling direction.

[0106] The cleaning robot 10 provided by the embodiment of the present application, wherein the cleaning member 11 can clean the surface to be cleaned 30 or self-clean to generate sewage. The sewage suction channel 14 communicates with the surface of the cleaning member 11 and the sewage tank 15. The sewage suction channel 14 provides a path for the sewage on the surface of the cleaning member 11 to enter the sewage tank 15. The suction fan 21 communicates with the sewage tank 15. When the suction fan 21 is in an operating state, the suction force generated by its suction wind can transfer the sewage generated on the surface of the cleaning member 11 to the sewage tank 15, so that the sewage generated when the cleaning member 11 performs cleaning work is collected by the electric energy of the cleaning robot 10 itself to drive the suction fan 21.

[0107] Wherein, the sewage tank 15 communicates with the main machine sewage docking port 191. When the cleaning robot 10 docks at the cleaning base station 20, the main machine sewage docking port 191 can be docked and communicated with the base station sewage docking port 22 on the cleaning base station 20. The sewage in the sewage tank 15 can be sucked by a fan provided inside the cleaning base station 20, so as to discharge the sewage in the sewage tank 15 to the cleaning base station 20, so that the sewage generated when the cleaning member 11 performs cleaning work is discharged by the electric energy of the cleaning base station 20 itself to drive the fan therein, making the sewage treatment of the cleaning robot 10 intelligent, so as to replace the existing scheme of squeezing sewage through structural parts or emptying the sewage tank 15 manually, improving the use convenience of the cleaning robot 10 and the user experience.

[0108] In some embodiments, the cleaning robot 10 further includes a mounting member 12. The mounting member 12 has a mounting cavity. The mounting cavity has an opening 120 facing the surface to be cleaned 30. The cleaning member 11 is rotationally assembled in the mounting cavity, and a part of the cleaning member 11 is located at the opening 120, allowing the surface of the cleaning member 11 to contact the surface to be cleaned 30. A suction space 13 is formed between the surface of the cleaning member 11 and the cavity wall of the mounting cavity. The suction space 13 extends in a direction opposite to the opening 120 from the position where the opening 120 is located. The sewage suction channel 14 communicates with the surface of the cleaning member 11 through the suction space 13.

[0109] Wherein, the cleaning robot 10 can enter the docking platform 21 of the cleaning base station 20 by backing up. When the cleaning robot 10 travels on the surface to be cleaned 30, the rotary brush contacts the surface to be cleaned 30, and the rotary brush rotates to clean the surface to be cleaned 30. When the cleaning robot 10 docks at the cleaning base station 20, the rotary brush contacts the bottom wall of the cleaning groove on the cleaning base station 20, and the rotary brush rotates and receives the self-cleaning pressure provided by the bottom wall of the cleaning groove to the rotary brush, so that the scraping brush realizes self-cleaning.

[0110] In this embodiment, the surface of the cleaning member 11 refers to the surface where the wool material for mopping or washing the floor is located on the cleaning member 11. Or, when the wool material has a certain thickness, the surface of the cleaning member 11 can refer to the entire circumferential surface formed by the circumferential extension of the thickness of the wool material.

[0111] Among them, the opening 120 is arranged so that a part of the cleaning member 11 can be exposed to the installation cavity for interference fit with the surface 30 to be cleaned to frictionally clean the surface 30 to be cleaned. Therefore, the opening direction of the opening 120 faces the surface 30 to be cleaned, and the cavity wall extending upward from the side of the opening 120 is opposite and spaced from the surface of the cleaning member 11, that is, the suction space 13 is formed by extending from the position where the opening 120 is located in the direction opposite to the opening direction of the opening 120.

[0112] When the position of the side of the opening 120 is low enough, the height of the suction space 13 from the surface 30 to be cleaned is low enough, which allows the cavity wall of the installation cavity and the surface of the cleaning member 11 to have sealing performance, and allows a negative pressure to be formed in the suction space 13 to suck the sewage and water stains on the surface 30 to be cleaned.

[0113] Generally, in order to have higher cleaning effect and cleaning efficiency, the axial length of the cleaning member 11 is designed to be longer, that is, the axial length of the suction space 13 is longer. In this case, since the suction space 13 has a longer axial dimension, the baffle-like structures can be cancelled at both axial sides of the suction space 13, and the suction space 13 can also generate sufficient suction wind force under the action of the suction fan 21 without being affected by the open settings at both axial sides.

[0114] Of course, in the best embodiment, baffle-like structures are respectively arranged at both axial sides of the suction space 13. The baffle-like structures can belong to the cleaning member 11 or be connected to other components in the cleaning robot 10. The baffle-like structures form a covering at both axial sides of the suction space 13, or at least partially cover both axial sides, providing the sealing performance of the suction space 13, and further making it easier for the suction fan 21 to form a negative pressure in the suction space 13, which is more conducive to sucking sewage and water stains.

[0115] Since a suction space 13 is formed between the surface of the cleaning member 11 and the cavity wall of the installation cavity of the installation member 12, and the suction space 13 extends from the position where the opening 120 of the installation member 12 is located in the direction opposite to the opening direction of the opening 120, that is, extends from the surface 30 to be cleaned upward above the surface 30 to be cleaned, and the suction fan 21 is communicated with the suction space 13, the sewage generated by cleaning the surface 30 to be cleaned on the surface of the cleaning member 11 can be sucked through the suction space 13.

[0116] The suction fan 21 is provided in the cleaning robot 10. The cleaning robot 10 travels on the surface 30 to be cleaned. The wind force applied by the suction fan 21 to the suction space 13 points from the surface 30 to be cleaned upward above the surface 30 to be cleaned. Therefore, the wind force of the suction fan 21 can be applied to the suction space 13 and the surface 30 to be cleaned, and then the sewage on the surface 30 to be cleaned and the cleaning member 11 can be sucked away. Intelligent sewage suction from the surface 30 to be cleaned to the sewage tank 15 is achieved through the suction wind force, improving the user experience.

[0117] In some embodiments, the opening 120 has two side edges oppositely arranged along the traveling direction of the cleaning robot 10, and at least one side edge is configured to be able to contact the surface 30 to be cleaned, so that the surface 30 to be cleaned, the wall of the installation cavity, and the surface of the cleaning member 11 form the suction space 13 when the cleaning robot 10 cleans the surface 30 to be cleaned. The sewage suction channel 14 communicates with the surface 30 to be cleaned through the suction space 13, and the suction fan 21 is also used to suck the sewage on the surface 30 to be cleaned into the sewage tank 15.

[0118] In some embodiments, the two side edges are arranged in parallel, and both are parallel to the axis of the cleaning member 11, that is, both are perpendicular to the traveling direction. The heights of the two side edges can be the same, or the height of one of the two side edges is higher than that of the other.

[0119] In some embodiments, one of the side edges of the opening 120 arranged on one side along the traveling direction of the cleaning robot 10 is configured to be able to contact the surface 30 to be cleaned. This side edge can be the front side edge 121 located on the front side of the traveling direction or the rear side edge 122 located on the rear side of the traveling direction. The surface 30 to be cleaned, the wall of the installation cavity, and the surface of the cleaning member 11 between one side edge and the cleaning member 11 form the suction space 13 when the cleaning robot 10 cleans the surface 30 to be cleaned. Compared with the suction space 13 formed by the wall of the installation cavity and the surface of the cleaning member 11, the suction space 13 formed by the three has better sealing performance. The suction fan 21 can suck more efficiently and achieve a better suction effect, and at the same time, it can ensure that the water stains on the surface 30 to be cleaned can be sucked more cleanly.

[0120] In some embodiments, both of the two side edges of the opening 120 that are oppositely arranged along the traveling direction of the cleaning robot 10 are configured to be able to contact the surface 30 to be cleaned. Since the two side edges are respectively located on both sides of the cleaning member 11, there are surfaces 30 to be cleaned between the cleaning member 11 and the two side edges. When the cleaning robot 10 cleans the surface 30 to be cleaned, a suction space 13 is formed among the surfaces 30 to be cleaned located on both sides of the cleaning member 11, the wall of the installation cavity, and the surface of the cleaning member 11. Compared with the suction space 13 formed by the wall of the installation cavity and the surface of the cleaning member 11, the suction space 13 formed by the three has better sealing performance. The suction fan 21 can perform suction more efficiently, achieve a better suction effect, and at the same time ensure that the water stains on the surface 30 to be cleaned can be sucked more cleanly.

[0121] It should be noted that when both of the two side edges of the opening 120 that are oppositely arranged along the traveling direction of the cleaning robot 10 are configured to be able to contact the surface 30 to be cleaned, a part of the area of the wall of the installation cavity 1 needs to be opened up for arranging a water outlet, and the water outlet is used to supply clean water to the cleaning member 11. The area where the water outlet is located is spaced apart from the suction space 13 to prevent the wind force of the suction fan 21 from affecting the supply of clean water.

[0122] As Figures 26 to 27 shown, the mounting member 12 is provided with a water storage tank 123. The water storage tank 123 extends along the axial direction of the cleaning member 11, and each water storage cell 1231 extends along the length direction of the cleaning member 11. A plurality of water storage cells 1231 are arranged in sequence along the same axial direction, and water outlet holes 1232 are respectively provided in the plurality of water storage cells 1231 arranged in sequence along the same axial direction. The plurality of water storage cells 1231 are arranged in parallel, and all the water storage cells 1231 form a maze pattern.

[0123] The mounting member 12 is provided with a detachable cover member 124. The cover member 124 covers the water storage tank 123, and the cover member 124 is provided with a water delivery hole 1241 to facilitate the clean water in the clean water tank to enter the water storage tank 123 through the water delivery hole 1241. By covering the notch of the water storage tank 123 with the cover member 124, the water storage tank 123 is sealed so that clean water is stored in the plurality of water storage cells 1231. The cover member 124 is detachably installed on the main body member, which is convenient for inspecting and maintaining the interior of the water storage tank 123 by removing the cover member 124.

[0124] As Figure 5 shown, in some embodiments, the two side edges are respectively the front side edge 121 and the rear side edge 122 arranged on the front side and the rear side in the traveling direction. The rear side edge 122 is configured to be able to contact the surface 30 to be cleaned, and the height of the front side edge 121 is higher than the height of the rear side edge 122.

[0125] When the cleaning member 11 is disposed on the rear side in the traveling direction, the rear side 122 contacts the surface 30 to be cleaned. Then, as the cleaning robot 10 travels forward in the traveling direction, the cleaning member 11 cleans the surface 30 to be cleaned, and the surface 30 to be cleaned between the rear side 122 and the cleaning member 11 has been cleaned. The suction fan 21 sucks this part of the surface 30 to be cleaned.

[0126] As Figure 5 shown, since the flannelette or bristles of the rotary brush are fluffy by themselves, the flannelette and bristles can be compressed. When designing the relative position of the rotary brush with respect to the cleaning robot 10, it is designed such that the maximum outer shape of the flannelette can be in interference fit with the surface 30 to be cleaned, so as to ensure that the flannelette or bristles of the rotary brush can be in full contact with the ground. At this time, the flannelette of the rotary brush rotating at high speed rubs against the surface 30 to be cleaned, and the flannelette of the rotary brush adsorbs the moisture and other dirt on the surface 30 to be cleaned. The side on the rear side of the rotary brush also adopts an interference fit with the surface 30 to be cleaned, and the side, the rotary brush, the surface 30 to be cleaned, and the installation cavity form a relatively airtight suction space 13. Since the outer shape of the flannelette or bristles of the rotary brush after being wetted becomes smaller, that is, the outer diameter size is reduced, a gap will appear between the side and the flannelette of the rotary brush. The negative pressure generated by the rotation of the suction fan 21 can pass through this gap and suck up the water stains remaining on the surface 30 to be cleaned and the surface of the rotary brush through the dirt suction port 1511 at the top of the rotary brush, so as to realize the intelligent suction and collection of sewage.

[0127] The above describes the process in which the suction fan 21 sucks the sewage on the surface of the cleaning member 11 and the surface 30 to be cleaned through the dirt suction channel 14, so as to realize the intelligent suction of the sewage on the surface of the cleaning member 11 and the surface 30 to be cleaned into the sewage tank 15.

[0128] As Figures 3 to 7 shown, in some embodiments, a dirt suction port 1511 is provided on the wall of the sewage tank 15, a sewage cavity 1512 is provided inside the sewage tank 15, and the dirt suction port 1511 communicates with the dirt suction channel 14 and the sewage cavity 1512. The sewage tank 15 is provided with a turning portion 1522a, which is formed by being recessed in a direction away from the sewage cavity 1512. The inside of the turning portion 1522a communicates with the sewage cavity 1512. The port of the dirt suction port 1511 communicating with the sewage cavity 1512 is located inside the turning portion 1522a and is spaced apart from it.

[0129] In this embodiment, the cleaning member 11, the dirt suction channel 14, the dirt suction port 1511, and the turning portion 1522a are arranged in sequence from bottom to top, and the suction force overcomes the gravity of the sewage to suck the sewage to the dirt suction port 1511. Of course, the cleaning member 11, the dirt suction channel 14, the dirt suction port 1511, and the turning portion 1522a can also be arranged in a direction at a certain angle to the horizontal direction, for example, inclined at a certain angle, as long as the turning portion 1522a is at the highest position of the sewage cavity 1512.

[0130] The turning part 1522a is formed by being recessed in a direction away from the sewage chamber 1512. The turning part 1522a forms an inner concave space facing the sewage chamber 1512, that is, the sewage suction port 1511 and this inner concave space are opposite and spaced apart from each other, and the sewage suction port 1511 can enter the inner concave space. This inner concave space blocks the sewage. After the sewage is sucked out of the sewage suction port 1511, the sewage is diverted by the inner concave space and flows into the inner concave space, that is, it is blocked by the turning part 1522a under its own gravity and falls along the direction of gravity, and just falls into the sewage chamber 1512.

[0131] Utilizing the gravity of the sewage itself, when the sewage is sucked from the sewage suction port 1511 to the inside of the turning part 1522a, since the sewage suction port 1511 and the inner wall of the turning part 1522a are spaced apart, the sewage can fall from top to bottom through this space under the action of gravity. With such a setting, not only can the gravity of the sewage itself be cleverly used to enter the bottom 1512c of the sewage chamber 1512, but also the direction of the suction wind force and the direction of the sewage are forcibly separated by the turning part 1522a, preventing the sewage from continuing to flow with the suction wind force, and thus the position of the suction fan 21 and the path of the suction wind force can be set flexibly.

[0132] Among them, preferably, the turning part 1522a is arranged directly above the center of the sewage chamber 1512. The sewage diverted and discharged from the turning part 1522a can fall into the bottom 1512c of the sewage chamber 1512 from the entire circumference, improving the sewage collection efficiency.

[0133] As Figures 3 to 5 shown, the bottom 1512c of the sewage tank 15 is stretched toward the side where the turning part 1522a is located to form a conical tube-like structure, and the sewage suction port 1511 is opened at the top of this conical tube-like structure. With such a setting, in order to ensure that the sewage suction port 1511 can extend into the inside of the turning part 1522a to achieve the function of using the turning part 1522a to block and turn the sewage, and the conical tube-like structure can accommodate the sewage suction channel 14, and the sewage suction channel 14 can be set in a shape adapted to the conical tube-like structure. In this way, the sewage suction channel 14 can be positioned more adaptively and stably, improving the compactness and integration of the internal structure of the cleaning robot 10.

[0134] In some embodiments, the sewage tank 15 is provided with an air passage chamber 1525, an air inlet 1522c, and an air outlet 1521a. The air passage chamber 1525 and the sewage chamber 1512 are arranged in the up-down direction. The air inlet 1522c communicates the sewage chamber 1512 with the air passage chamber 1525. The air passage chamber 1525 communicates the air inlet 1522c with the air outlet 1521a. The air outlet 1521a communicates the air passage chamber 1525 with the suction fan 21. Among them, the air inlet 1522c and the air outlet 1521a are provided on both sides of the sewage suction port 1511 or the turning portion 1522a in the horizontal direction. Among them, in order to prevent the suction force from interfering with the sewage in the sewage chamber 1512, the air passage chamber 1525 can be arranged directly above the sewage chamber 1512, and at least the air inlet 1522c is far above the highest water level of the sewage tank 15.

[0135] Since the sewage suction port 1511 and the turning portion 1522a are opposite and spaced apart, the space therebetween not only allows the sewage to be blocked and redirected into the sewage tank 15. Similarly, the space between the sewage suction port 1511 and the turning portion 1522a can redirect the suction force. Since the air passage chamber 1525 and the sewage chamber 1512 are communicated through the air inlet 1522c, and the air inlet 1522c, the air passage chamber 1525, the air outlet 1521a, and the suction fan 21 are communicated in sequence, the suction force applied by the suction fan 21 can enter the air inlet 1522c after being redirected by the turning portion 1522a, and flow out of the sewage tank 15 through the air passage chamber 1525 and the air outlet 1521a.

[0136] Since the air inlet 1522c and the air outlet 1521a are provided on both sides of the sewage suction port 1511 or the turning portion 1522a in the horizontal direction, that is, the air inlet 1522c and the air outlet 1521a are separated by the extension dimension of the air passage chamber 1525 in this spaced direction, the suction path of the suction force inside the sewage tank 15 is lengthened, which can prevent the water vapor carried out by the suction force from being carried out of the sewage tank 15 and affecting the function of the suction fan 21, as well as other components located outside the sewage tank 15 on the cleaning robot 10.

[0137] In some embodiments, in order to further prevent the suction force from carrying the water vapor out of the sewage tank 15, the sewage tank 15 is further provided with a water vapor adsorbent 1526. The water vapor adsorbent 1526 is arranged in the air passage chamber 1525 and close to the air outlet 1521a. For example, it can be an adsorbent made of porous material, such as a water vapor filtering material, a sponge, or a multi-layer filter sheet.

[0138] In other embodiments, the air passage chamber 1525 and the air inlet 1522c may not be provided. A water vapor adsorbent 1526 can be separately provided at the air outlet 1521a between the sewage tank 15 and the suction fan 21, and the purpose of adsorbing water vapor can also be achieved.

[0139] In some embodiments, the sewage tank 15 includes a tank body 151 and a cover body 152 connected to the tank body 151. A sewage chamber 1512 is provided inside the tank body 151, a sewage suction port 1511 is provided on the tank wall of the tank body 151, the sewage chamber 1512 has an opening 1513, and the cover body 152 is configured to be able to close or open the opening 1513. The cover body 152 is provided with an air passage chamber 1525, an air inlet 1522c and an air outlet 1521a. When the cover body 152 closes the opening 1513, the air inlet 1522c communicates the sewage chamber 1512 and the air passage chamber 1525.

[0140] By configuring the sewage tank 15 as a tank body 151 structure that can be opened or closed, it is convenient to manufacture the air inlet 1522c and the turning portion 1522a, and it is also convenient to inspect and repair the inside of the sewage tank 15 through the opening 1513. The turning portion 1522a is provided on the side of the cover body 152 facing the sewage chamber 1512. When the cover body 152 closes the opening 1513 of the tank body 151, the turning portion 1522a can just enclose the sewage suction port 1511, and the inner wall of the turning portion 1522a is spaced apart from the sewage suction port 1511 by a certain distance, allowing sewage and suction wind force to pass through and turn.

[0141] Among them, as Figure 8 shown, from the overall view of the cleaning robot 10, the air inlet 1522c, the turning portion 1522a, the air outlet 1521a and the suction fan 21 are arranged in a direction perpendicular to the cleaning robot 10, making full use of the space of the cleaning robot 10 in this direction and improving the compactness and integration inside the cleaning robot 10.

[0142] In some embodiments, the cover body 152 includes an outer cover body 1521 and an inner cover body 1522. The inner cover body 1522 is provided inside the outer cover body 1521, and at least one of the outer cover body 1521 and the inner cover body 1522 is configured to be able to close or open the opening 1513. The inner cover body 1522 and the outer cover body 1521 are spaced apart to form the air passage chamber 1525. The air inlet 1522c is provided on the inner cover body 1522, and the air outlet 1521a is provided on the outer cover body 1521.

[0143] Exemplarily, in some embodiments, the outer cover body 1521 is formed by stretching to have a cavity. The opening of the cavity faces the side where the sewage chamber 1512 is located, and the inner cover body 1522 covers the opening of the cavity. The inner cover body 1522 and the outer cover body 1521 together define the structure of the air passage chamber 1525. Among them, both the outer cover body 1521 and the inner cover body 1522 are rigid members with a certain hardness, and an elastic ring seal 1524 can be clamped in the circumferential direction where they are in contact and closed. The ring seal 1524 and the above-mentioned second soft rubber member 1524a can improve the sealing performance between the two.

[0144] As Figure 8 shown, in some embodiments, in the direction from the air passage cavity 1525 to the suction fan 21, the duct of the air outlet 1521a can be inclined downward at a certain angle, for example, it can be inclined by 10°, or at least a part of the lower side of the air outlet 1521a is inclined at a certain angle. And a structure of the air outlet 1521a can be installed on this part, the air outlet 1521a is provided on the structure of the air outlet 1521a, and a first soft rubber part 1527 can be arranged between the structure of the air outlet 1521a and the outer cover 1521.

[0145] With such a setting, when the sewage tank 15 is loaded and unloaded on the cleaning robot 10, the first soft rubber part 1527 will not be sheared, which can protect the service life of the first soft rubber part 1527 and the air outlet 1521a itself. Moreover, after the sewage tank 15 is in place, through the inclined setting, a horizontal component force can be generated, and then the air outlet 1521a is squeezed to achieve a good sealing effect.

[0146] In some embodiments, the inner cover 1522 is provided with a convex part 1522b protruding towards the outer cover 1521, the top surface of the convex part 1522b is higher than the highest water level line of the sewage cavity 1512, and the air inlet 1522c is opened on the top surface, so as to reduce the risk of sewage entering the air passage cavity 1525 due to shaking during the walking of the cleaning robot 10.

[0147] As Figure 3 and Figure 8 shown, a turning part 1522a for opposing and spacing from the sewage suction port 1511 is arranged on the inner cover 1522, the turning part 1522a surrounds the sewage suction port 1511 and separates a certain gap from it, avoiding the sewage sucked up from the sewage suction channel 14 from splashing onto the surrounding walls of the entire cover 152 and the box body 151, which affects the user experience. The turning part 1522a can change the direction of the sewage sucked from the sewage suction port 1511, so that the sewage falls downward into the bottom 1512c of the sewage tank 15 after being changed in direction. At the same time, the turning part 1522a can also change the direction of the air flow sucked from the sewage suction port 1511. The water content in the air flow is relatively high. After the air flow impacts the turning part 1522a, part of the water vapor in the air flow condenses into water on the turning part 1522a and falls along the inner wall of the turning part 1522a to the bottom 1512c of the sewage tank 15. At the same time, by arranging the air inlet 1522c, the air passage cavity 1525 and the air outlet 1521a, the changed air flow can avoid flowing directly from the sewage suction port 1511 to the air outlet 1521a, preventing more water vapor from being brought into the suction fan.

[0148] The above has described that by providing an air passage cavity 1525 to connect the sewage cavity 1512 and the suction fan 21, and lengthening the path distance between the air inlet 1522c and the air outlet 1521a, it is possible to prevent the suction wind force from taking out water vapor from the sewage tank 15, and to realize the intelligent collection of sewage through the suction fan 21.

[0149] Referring to Figures 10 to 14 As shown, in some embodiments, the sewage tank 15 is provided with a sewage outlet 1514 and a sewage discharging member 1528 disposed in the sewage cavity 1512. The sewage outlet 1514 is communicated with the main machine sewage docking port 191; the sewage discharging member 1528 is provided with a sewage discharging channel 1528a, and the sewage discharging channel 1528a has a first port A and a second port B that are communicated with each other. The first port A is communicated with the sewage cavity 1512, and the side of the sewage discharging member 1528 where the first port A is located is adjacent to the bottom 1512c of the sewage cavity 1512 and is spaced from the bottom 1512c, and the second port B is communicated with the sewage outlet 1514.

[0150] The sewage discharging member 1528 is used to connect the sewage cavity 1512 and the sewage outlet 1514. Of course, the sewage cavity 1512 can be directly communicated with the sewage outlet 1514, and there is no need to provide a sewage discharging member 1528 therebetween. For example, the sewage outlet 1514 can be provided at the bottom 1512c of the sewage tank 15.

[0151] In this embodiment, since all the sewage inside the sewage tank 15 needs to be discharged without residue to ensure the cleanliness of the inside of the sewage tank 15 and prevent the growth of bacteria from reducing the user experience. And, during the cleaning process of the cleaning robot 10, it is preferably that the sewage does not reach the sewage outlet 1514 temporarily to prevent the internal pressure on the sewage outlet 1514 from damaging the sealing performance of the sewage outlet 1514. In addition, the sewage level in the cleaning robot 10 will continue to rise during the cleaning process, and the discharge of sewage needs to wait until the cleaning robot 10 docks at the cleaning base station 20 before proceeding.

[0152] Based on the above reasons, in this embodiment, a sewage discharging member 1528 is provided in the sewage cavity 1512, so that the side of the sewage discharging member 1528 where the first port A is located is adjacent to the bottom 1512c of the sewage cavity 1512 and is spaced from the bottom 1512c, and the second port B is communicated with the sewage outlet 1514. In this way, the sewage can be discharged from the bottom 1512c of the sewage cavity 1512 through the first port A, and the water level of the sewage in the sewage cavity 1512 can reach the set water level during the cleaning process.

[0153] In some embodiments, the sewage discharging member 1528 includes a first pipe portion 1528b, a second pipe portion 1528b, and a third pipe portion 1528c that are sequentially communicated. The first pipe portion 1528b and the third pipe portion 1528c extend in the vertical direction, and the second pipe portion 1528b extends in the horizontal direction;

[0154] The second pipe portion 1528b is connected between the top end of the first pipe portion 1528b and the top end of the second pipe portion 1528b. The port on the first pipe portion 1528b away from the second pipe portion 1528b is the first port A, and the port on the third pipe portion 1528c away from the second pipe portion 1528b is the second port B.

[0155] Among them, the top ends of the first pipe portion 1528b and the third pipe portion 1528c can be flush, that is, the top ends of the first pipe portion 1528b and the third pipe portion 1528c are at the same height. The length of the first pipe portion 1528b is greater than that of the third pipe portion 1528c, and the second pipe portion 1528b extends in the horizontal direction. Sewage is discharged from the bottom 1512c of the sewage chamber 1512 through the first port A of the first pipe portion 1528b to ensure that the sewage inside the sewage chamber 1512 can be completely discharged.

[0156] Among them, a water level detector 1529 is further provided inside the sewage chamber 1512. A channel structure 1512f extending in the vertical direction is provided on the inner side of the chamber wall of the sewage chamber 1512. The water level detector 1529 is movably installed in the channel structure 1512f. Under the buoyancy of the sewage, the water level detector 1529 can move up and down along the channel structure 1512f to obtain the current water level inside the sewage chamber 1512 in real time.

[0157] In some embodiments, the sewage tank 15 is further provided with a filter member 1530. The sewage chamber 1512 is configured to be separated into a first chamber portion 1512d and a second chamber portion 1512e by the filter member 1530 and communicated through the filter member 1530. The turning portion 1522a and the sewage suction port 1511 are provided in the area where the first chamber portion 1512d is located, and the sewage discharging member 1528 is provided in the second chamber portion 1512e. The above-mentioned channel structure 1512f and the water level detector 1529 are provided in the second chamber portion 1512e. Among them, the filter member 1530 can divide the opening 1513 of the sewage chamber 1512 into two parts, and the cover body 152 can simultaneously close or open these two parts.

[0158] Among them, the filter member 1530 can be a filter net, and the sewage tank 15 is further provided with a filter net. The filter net and the sewage discharging member 1528 in the sewage tank 15 can both be detachable structures. When the sewage discharging channel 1528a of the filter net or the sewage discharging member 1528 is blocked, it can be disassembled for cleaning and maintenance.

[0159] The filter is used to filter garbage with larger particles to prevent clogging of the sewage outlet channel 1528a of the sewage outlet 1528. The filter is detachably mounted on the inner wall of the sewage chamber 1512, and is disposed between the sewage suction port 1511 and the sewage outlet 1528. The filter divides the sewage chamber 1512 into two areas, a first chamber 1512d and a second chamber 1512e. The sewage collected from the roller brush and the surface to be cleaned 30 enters the sewage tank 15, which may carry a large amount of impurities and other particulate matter. The sewage first enters the first chamber 1512d, and the sewage in the first chamber 1512d is filtered by the filter and enters the second chamber 1512e, and then the sewage is discharged from the sewage tank 15 through the sewage outlet 1528 disposed in the second chamber 1512e, while the larger impurity particles are blocked by the filter in the first chamber 1512d. The clean water channel 1522d described below can also be used to spray and clean the filter from top to bottom, so as to help clean the impurities that are attached to the filter due to filtration.

[0160] Furthermore, a water level detector 1529 is arranged inside the sewage tank 15. When the sewage water level in the sewage tank 15 reaches the designed maximum water level, the water level detector 1529 floats up, and the cleaning robot 10 returns to the cleaning base station 20 to drain the sewage. Under the action of the negative pressure of the fan of the cleaning base station 20, the sewage in the sewage tank 15 enters the sewage outlet channel 1528a in the sewage outlet part 1528 of the sewage tank 15, and then flows out of the sewage tank 15 through the sewage outlet 1514, and is collected in the sewage tank 15 of the base station through the host sewage docking interface 191, or the sewage is discharged by the water supply and drainage devices of the cleaning base station 20, thereby emptying the sewage tank 15.

[0161] Reference Figures 22 to 25 As shown, in some embodiments, the cleaning robot 10 further includes a docking assembly 19 and an adapter assembly 16, and a sewage pipe 17. The adapter assembly 16 is detachably mounted on the outer side of the box wall of the sewage tank 15, and the adapter assembly 16 is provided with a sewage transfer channel 161, which is docked and connected with the sewage outlet 1514, and the sewage pipe 17 is connected with the host sewage docking port 191 and the sewage transfer channel 161. The docking assembly 19 is provided with a host sewage docking port 191, and the host sewage docking port 191 is provided for docking and connecting with the base station sewage docking port 22 of the cleaning base station 20 when the cleaning robot 10 is docked at the cleaning base station 20.

[0162] When the cleaning robot 10 is docked at the cleaning base station 20, the host sewage docking port 191 on the cleaning robot 10 can be docked and connected with the base station sewage docking port 22 on the cleaning base station 20, and the sewage in the sewage tank 15 can be sucked by the fan provided inside the cleaning base station 20 to discharge the sewage in the sewage tank 15 to the cleaning base station 20, so that the sewage generated by the cleaning part 11 during cleaning work can be discharged through the fan driven by the electric energy of the cleaning base station 20 itself, making the sewage treatment of the cleaning system intelligent, improving the convenience of using the cleaning robot 10, and improving the user experience.

[0163] The above illustrates that after the sewage in the sewage chamber 1512 is filtered, it is discharged from the sewage chamber 1512 by the sewage discharge component 1528, and is discharged to the cleaning base station 20 through the adapter component 16, the sewage pipeline 17 and the host sewage interface 191, thereby realizing the intelligent sewage discharge part of the cleaning robot 10.

[0164] Reference Figures 15 to 21 As shown, in some embodiments, the wall of the sewage tank 15 is further provided with a clean water inlet 1515 and a sewage outlet 1514, and a clean water channel 1522d is provided inside the sewage tank 15. The clean water inlet 1515 is in communication with the clean water channel 1522d, and the clean water supplied to the outside of the sewage tank 15 by the clean water inlet 1515 is supplied to the clean water channel 1522d, and the sewage supplied to the sewage chamber 1512 by the sewage outlet 1514 is drained to the outside of the sewage tank 15. The clean water channel 1522d is in communication with the sewage chamber 1512, and the clean water channel 1522d provides a path for the clean water to be sprayed toward the sewage chamber 1512 so that the clean water is sprayed to clean the sewage chamber 1512.

[0165] The clean water inlet 1515 is connected to the clean water channel 1522d, and the clean water outside the sewage tank 15 can be supplied to the clean water channel 1522d through the clean water inlet 1515. The sewage outlet 1514 is connected to the sewage chamber 1512, and the sewage in the sewage chamber 1512 can be drained to the outside of the sewage tank 15 through the sewage outlet 1514. Among them, the clean water channel 1522d is connected to the sewage chamber 1512, and the clean water entering the sewage tank 15 can be sprayed toward the sewage chamber 1512 through the clean water channel 1522d, thereby cleaning the sewage chamber 1512, and the sewage generated by cleaning the sewage chamber 1512 is discharged from the sewage tank 15 through the sewage outlet 1514.

[0166] Through the clean water outlet 1515 and the sewage outlet, clean water can enter the interior of the sewage tank 15 to clean the sewage cavity 1512, and the sewage generated by the cleaning can be discharged from the sewage tank 15 through the sewage outlet 1514, so that a water path for self-cleaning of the sewage tank 15 is formed inside the sewage tank 15, and the fan or pump body can be driven by electric energy to achieve water driving, thereby realizing self-cleaning intelligent processing of the sewage tank 15, thereby improving the user experience.

[0167] In some embodiments, a blower or a pump body driven by electric energy can be used to drive clear water and sewage. Similarly, the clear water in the clear water circuit can be sprayed towards the cavity wall of the sewage cavity 1512 by using the blower or the pump body.

[0168] In some embodiments, the clear water channel 1522d and the sewage cavity 1512 are arranged in sequence along the vertical direction, and the clear water channel 1522d is configured such that clear water can be sprayed towards the sewage cavity 1512 by gravity.

[0169] In some embodiments, the clear water in the clear water circuit can be sprayed towards the cavity wall of the sewage cavity 1512 by using a blower or a pump body, or the clear water channel 1522d and the sewage cavity 1512 can be arranged in sequence along the vertical direction, and the clear water channel 1522d is configured such that clear water can be sprayed towards the sewage cavity 1512 by gravity. By the combined action of electric energy drive and gravity drive, the spraying speed or strength of the clear water on the sewage cavity 1512 is increased, and the cleaning effect and efficiency of self-cleaning are improved.

[0170] In some embodiments, the clear water channel 1522d includes a main channel 1522e and a plurality of spray channels 1522f. The main channel 1522e is annular, the main channel 1522e is arranged around the vertical direction, and the main channel 1522e is communicated with the clear water inlet 1515; the plurality of spray channels 1522f are arranged at intervals along the circumferential direction of the main channel 1522e, and the spray channels 1522f are communicated with the main channel 1522e and the sewage cavity 1512.

[0171] Since the plurality of spray channels 1522f are arranged at intervals along the circumferential direction of the main channel 1522e, the spray channels 1522f can be arranged comprehensively along the circumferential direction of the main channel 1522e. This arrangement can enable the clear water to be sprayed onto the peripheral walls of the cavity of the sewage tank 15, realizing a cleaning of the sewage cavity 1512 without dead angles.

[0172] In some embodiments, the sewage cavity 1512 has a cavity wall arranged around the vertical direction. The clear water channel 1522d is arranged at intervals inside the cavity wall; alternatively, the clear water channel 1522d and the cavity wall are arranged flush with each other along the vertical direction.

[0173] In some embodiments, when the clear water channel 1522d is arranged at intervals inside the cavity wall, the spray port of the clear water channel 1522d can be arranged towards the cavity wall, that is, arranged radially outward along the clear water channel 1522d. In some embodiments, when the clear water channel 1522d and the cavity wall are arranged flush with each other along the vertical direction, the clear water channel 1522d is arranged above the cavity wall or on the upper side of the cavity wall along the vertical direction, and the clear water flows downward along the cavity wall by gravity, thereby realizing the cleaning of the cavity wall. In some embodiments, the clear water channel 1522d can be arranged on a rotating head that can rotate relative to the sewage tank 15. When the rotating head rotates relative to the sewage tank 15, the sewage cavity 1512 can be cleaned without dead angles.

[0174] In some embodiments, the sewage chamber 1512 has a chamber wall arranged around the vertical direction, and the clean water channel 1522d is spaced inside the chamber wall. The spray channel 1522f includes a first part a and a second part b. The first part a extends in the vertical direction, and the second part b is arranged at an angle to the first part a; the first part a communicates with the main channel 1522e and the second part b, and the second part b communicates with the first part a and the sewage chamber 1512. Wherein, one end of the second part b away from the first part a is arranged towards the chamber wall.

[0175] The clean water channel 1522d and the spray channel 1522f are arranged above the highest water level of the sewage tank 15. The second part b of the spray channel 1522f is arranged at an angle to the first part a, and one end of the second part b away from the first part a is arranged towards the chamber wall. In this way, by designing the structure of the spray channel 1522f, the clean water can be turned in the spray channel 1522f, changing from the vertical direction to a direction at an angle to the vertical direction, such as the horizontal direction or the inclined direction. Utilize the impact force of the clean water in the horizontal or inclined direction to clean the chamber wall of the sewage chamber 1512, improving the cleaning effect and efficiency. For example, the angle of the spray channel 1522f relative to the horizontal plane can be 0 degrees or biased 0-45° downward.

[0176] In some embodiments, in the first part a and the second part b, at least the second part b has an extension dimension along the circumferential direction of the main channel 1522e greater than the extension dimension along the vertical direction.

[0177] That is to say, the spray channel 1522f is a flat hole structure extending in the horizontal direction with a certain length, which can extend the dimension of the spray channel 1522f along the circumferential direction of the main channel 1522e, maximizing the spray area of each spray channel 1522f, and enabling the ejected clean water to wash the chamber wall of the sewage chamber 1512 to the greatest extent.

[0178] In some embodiments, the sum of the cross-sectional areas of the plurality of spray channels 1522f is smaller than the cross-sectional area of the clean water port 1515, so as to increase the water pressure of the spray channel 1522f, achieve the purpose of pressurized spraying and cleaning the chamber wall of the sewage chamber 1512, and improve the cleaning effect and efficiency.

[0179] In some embodiments, the sewage tank 15 includes a tank body 151 and a cover body 152 connected to the tank body 151. The tank body 151 is provided with a sewage chamber 1512, the sewage chamber 1512 has an opening 1513, and the cover body 152 is configured to be able to close or open the opening 1513. A clear water channel 1522d is provided on the side of the cover body 152 facing the sewage chamber 1512; wherein, a sewage outlet 1514 is provided on the tank body 151, and a clear water outlet 1515 is provided on one of the tank body 151 and the cover body 152.

[0180] The water tank includes a tank body 151 and a cover body 152 connected to the tank body 151. This design can meet the requirement that the cover body 152 can be opened to manually clean the inside of the sewage tank 15, and can also meet the waterway connection for self-cleaning of the sewage tank 15, realizing the self-cleaning function of the sewage tank 15 under normal circumstances, and can also be manually cleaned when the pipeline of the sewage tank 15 is abnormally blocked.

[0181] In some embodiments, the cover body 152 includes an outer cover body 1521 and an inner cover body 1522. The inner cover body 1522 is provided inside the outer cover body 1521, and at least one of the outer cover body 1521 and the inner cover body 1522 is configured to be able to close or open the opening 1513. An air passage cavity 1525 is formed by spacing at least part of the inner cover body 1522 and the outer cover body 1521, and the clear water channel 1522d is provided on the inner cover body 1522.

[0182] Through the arrangement of the outer cover body 1521 and the inner cover body 1522, the cover body 152 not only meets the requirement of being able to set the clear water channel 1522d, but also can connect the sewage suction port 1511 and the suction fan 21 through the air passage cavity 1525. The clear water channel and the air passage cavity 1525 are centrally arranged on the cover body 152, realizing the dual functions of sucking sewage and providing clear water, and can make the structure of the cover body 152 compact and centralized.

[0183] In some embodiments, a water diversion channel 1516 is provided on the wall of the tank body 151. The water diversion channel 1516 has a clear water outlet 1515 and a first water diversion port 1517 arranged opposite to each other, and the first water diversion port 1517 and the opening 1513 face the same direction. The inner cover body 1522 is provided with a second water diversion port 1522g. The clear water channel 1522d is communicated with the second water diversion port 1522g, and the second water diversion port 1522g and the first water diversion port 1517 are communicated with each other when the cover body 152 closes the opening 1513.

[0184] By providing a water diversion channel 1516 on the wall of the box body 151, clear water is supplied to the second water diversion port 1522g through the water diversion channel 1516, and then enters the clear water channel 1522d. Wherein, a sealing second soft rubber part 1524a can be provided on one side of the second water diversion port 1522g facing the water diversion channel 1516. When the cover 152 of the sewage tank 15 is closed, an interference fit is generated between the second soft rubber part 1524a and the first water diversion port 1517, so that the water diversion channel 1516 is hermetically connected to the clear water channel 1522d.

[0185] In some embodiments, the cover 152 has a rotation side 152a and an opening / closing side 152b arranged oppositely. The box body 151 is provided with a first cavity wall 1512a and a second cavity wall 1512b arranged oppositely. The cover 152 is rotatably connected to the first cavity wall 1512a through the rotation side 152a, and the opening / closing side 152b is detachably connected to the second cavity wall 1512b. The sewage outlet 1514 and the water diversion channel 1516 are arranged on the second cavity wall 1512b, and the sewage outlet 1514 and the clear water outlet 1515 are arranged flush with each other in the vertical direction.

[0186] In some embodiments, the cover 152 further includes a water channel sealing part 1523. The water channel sealing part 1523 covers the inner cover 1522 from the side where the outer cover 1521 is located, and at least covers the part of the clear water channel 1522d that is open towards the outer cover 1521. Wherein, the water channel sealing part 1523 can have the same structure as the main water channel 1522e, or can be in a plate-like or sheet-like structure.

[0187] In some embodiments, a sewage suction port 1511 is provided on the wall of the box body 151. The sewage suction port 1511 is communicated with the sewage cavity 1512, and the sewage suction port 1511 is used for sucking the sewage outside the sewage tank 15 into the sewage cavity 1512; the clear water channel 1522d is annular, and the part of the inner cover 1522 surrounded by the clear water channel 1522d is recessed towards the side where the outer cover 1521 is located to form a sewage turning part 1522a, and the sewage suction port 1511 is located inside the sewage turning part 1522a and is arranged at an interval from it.

[0188] The portion of the inner cover 1522 surrounded by the clean water channel 1522d is recessed toward the side of the outer cover 1521 to form the above-mentioned turning portion 1522a. The sewage suction port 1511 is located on the inner side of the turning portion 1522a and is spaced apart from it, while a plurality of spray water channels 1522f are arranged around the outer side of the turning portion 1522a. This allows the plurality of spray water channels 1522f to perform circumferential spray cleaning on the cavity wall of the sewage cavity 1512, and the clean water channel 1522d and the sewage suction port 1511 opposite to the turning portion 1522a can be designed with the turning portion 1522a as the center, so that sewage diversion, suction wind diversion and circumferential spraying of self-cleaning clean water can be achieved while this part of the structure is designed in a highly compact and highly centralized manner, cleverly utilizing the limited space in the sewage tank 15 to achieve a multifunctional design.

[0189] Reference Figures 22 to 25 As shown, in some embodiments, the cleaning robot 10 further includes a docking assembly 19 and an adapter assembly 16, and a clean water pipeline 18. The docking assembly 19 is provided with a host clean water docking port 192, and the host clean water docking port 192 is provided for docking and connecting to the base station clean water docking port 23 of the cleaning base station 20 when the cleaning robot 10 is docked at the cleaning base station 20. The adapter assembly 16 is detachably mounted on the outer side of the tank wall of the sewage tank 15, and the adapter assembly 16 is provided with a clean water transfer channel 162, and the clean water transfer channel 162 is docked and connected to the clean water port 1515, and the clean water pipeline 18 connects the host clean water docking port 192 and the clean water transfer channel 162.

[0190] When the cleaning robot 10 is docked at the cleaning base station 20, the host clean water docking port 192 on the cleaning robot 10 can be docked and connected with the base station clean water docking port 23 on the cleaning base station 20, and the clean water in the base station can be pumped into the clean water channel 1522d of the sewage tank 15 by the pump provided inside the cleaning base station 20, so that the sewage tank 15 can pump clean water by driving the pump therein through the electric energy of the cleaning base station 20 itself, making the self-cleaning work of the sewage tank 15 in the cleaning system intelligent, thereby improving the convenience of using the cleaning robot 10 and improving the user experience.

[0191] More specifically, the host clean water docking port 192 docks with the base station clean water docking port 23 on the cleaning base station 20 when the cleaning robot 10 returns to the cleaning base station 20, and injects clean water into the clean water tank or sewage tank 15 of the cleaning robot 10 through the pump body inside the cleaning base station 20. Clean water is injected into the clean water tank of the cleaning robot 10 to achieve the purpose of replenishing water when the clean water tank of the cleaning robot 10 is short of water or the water volume is insufficient, and clean water is provided to the sewage tank 15 of the cleaning robot 10, and the clean water is sprayed to the wall of the sewage cavity 1512 through the clean water channel 1522d in the sewage tank 15 to achieve the purpose of automatically cleaning the sewage tank 15.

[0192] When the main body of the cleaning robot 10 returns to the cleaning base station 20, the main body sewage docking port 191 of the cleaning robot 10 docks with the base station sewage docking port 22 on the cleaning base station 20. The sewage in the sewage tank 15 of the cleaning robot 10 is recovered to the cleaning base station 20 through a blower or air pump inside the cleaning base station 20. The above-mentioned method injects clean water into the sewage tank 15 of the cleaning robot 10 through the cleaning base station 20 to clean the sewage tank 15, and then the sewage in the sewage tank 15 of the cleaning robot 10 is recovered to the base station, emptying the cleaning robot 10, achieving the function of automatically recovering and discharging sewage. When the cleaning robot 10 returns to the cleaning base station 20 once, it can be set to inject clean water into the sewage tank 15 of the cleaning robot 10 multiple times, and then recover the sewage in the sewage tank 15, achieving the purpose of repeated flushing, making the self-cleaning effect of the sewage tank 15 better. This process can be repeated multiple times according to needs until the inside of the sewage tank 15 of the cleaning robot 10 becomes clean.

[0193] Among them, as Figure 24 and Figure 25 shown, annular seals 163 are provided outside the ports on the transfer assembly 16 for docking with the sewage outlet 1514 and the clean water outlet 1515. An overflow pipe 164 extending downward is provided on the lower side of the transfer assembly 16. Correspondingly, an overflow platform 165 facing upward is provided on the upper side of the transfer assembly 16. The liquid overflowing from the transfer assembly 16 can enter the overflow platform 165 and then flow out through the overflow pipe 164.

[0194] The above explains that the clean water in the cleaning base station 20 can pass through the pump in it, successively through the main body clean water docking port 192, the clean water pipeline 18, the transfer assembly 16, the clean water outlet 1515, the water diversion channel 1516, and finally be pumped to the clean water channel 1522d, and the sewage chamber 1512 is self-cleaned through the clean water channel 1522d, realizing the part of the intelligent self-cleaning of the sewage tank 15 by the cleaning robot 10.

[0195] As above, the cleaning robot 10 provided by the embodiment of the present application can not only intelligently collect the sewage on the surface to be cleaned 30 and the surface of the cleaning part 11 through the suction fan 21, but also intelligently discharge the sewage in the sewage tank 15 through the sewage discharge part 1528, the transfer assembly 16, the sewage pipeline 17 and the docking assembly 19. It can also realize the intelligent self-cleaning function of the sewage tank 15 through the docking assembly 19, the clean water pipeline 18, the transfer assembly 16, the water diversion channel 1516 and the clean water channel 1522d. From the collection and discharge of sewage and the self-cleaning of the sewage tank 15, the intelligent treatment of the sewage of the cleaning robot 10 is realized in all aspects, maximizing the user experience of the cleaning robot 10 for users.

[0196] In some embodiments, for the cleaning robot 10 provided in the embodiments of the present application, when the cleaning robot 10 performs mopping or floor washing work, the suction fan 21 sucks the surface of the cleaning member 11 and the surface to be cleaned 30, and collects the sewage into the sewage chamber 1512 of the sewage tank 15 through the suction wind force. When the water level detector 1529 of the sewage tank 15 detects that the sewage tank 15 is full or the cleaning work is completed, the cleaning robot 10 returns to the cleaning base station 20 for sewage discharge.

[0197] At this time, there are two cases. One is that the cleaning robot 10 detects that the sewage tank 15 is full during the execution of the cleaning task. The cleaning robot 10 directly returns to the cleaning base station 20 to empty the sewage in the sewage tank 15, and then comes out to continue executing the unfinished cleaning task. The other is that after the cleaning task is completed, the cleaning robot 10 returns to the cleaning base station 20 for sewage discharge, and then performs self-cleaning.

[0198] Regarding the self-cleaning process of the sewage tank 15, when the cleaning robot completes the cleaning task and returns to the cleaning base station 20, regardless of whether the sewage tank 15 is full, first empty the sewage in the sewage tank 15, then inject clean water from the cleaning base station 20 into the sewage tank 15 for spray washing, and then empty the sewage tank 15 again to prepare for the next cleaning task. The actions of injecting clean water to spray the sewage tank 15 and then emptying the sewage tank 15 can be set multiple times to achieve a better cleaning effect.

[0199] In this way, from collecting the sewage on the surface to be cleaned 30, to discharging the sewage back to the cleaning base station 20, then spray washing the sewage tank 15, and then emptying the sewage in the sewage tank 15, the whole process is completely realized by the mutual cooperation of the sewage suction path, the self-cleaning path, and the sewage pumping path, which is completely automated and intelligent, without manual operation and maintenance, and improves the user experience.

[0200] Refer to Figure 29 and Figure 30 As shown, another object of the embodiments of the present application is also to provide a cleaning system, which includes a cleaning base station 20 and the above-mentioned cleaning robot 10; wherein, the cleaning base station 20 is provided with a base sewage docking port 22 and a docking station 21. The cleaning robot 10 is configured to be able to dock at the docking station 21, and when the cleaning robot 10 is docked at the docking station 21 in place, the host sewage docking port 191 and the base sewage docking port 22 are docked and communicated.

[0201] In the cleaning system provided by the embodiment of the present application, when the cleaning robot 10 docks at the cleaning base station 20 therein, the main machine sewage docking port 191 on the cleaning robot 10 can be docked and communicated with the base station sewage docking port 22 on the cleaning base station 20. The sewage in the sewage tank 15 can be sucked by a blower provided inside the cleaning base station 20, so as to discharge the sewage in the sewage tank 15 to the cleaning base station 20, enabling the sewage generated by the cleaning member 11 during the cleaning work to be discharged by the electric energy of the cleaning base station 20 itself to drive the blower therein, making the sewage treatment of the cleaning system intelligent, improving the convenience of use of the cleaning robot 10, and enhancing the user experience.

[0202] Further, the sewage tank 15 is provided with a clean water inlet 1515, a clean water channel 1522d, and a sewage outlet 1514. The cleaning robot 10 is further provided with a main machine clean water docking port 192, and the cleaning base station 20 is further provided with a base station clean water docking port 23. The main machine clean water docking port 192, the clean water inlet 1515, the clean water channel 1522d, and the sewage chamber 1512 are communicated. The clean water channel 1522d provides a path for the clean water to spray towards the sewage chamber 1512, so that the clean water sprays to clean the sewage chamber 1512. When the cleaning robot 10 is docked in place at the docking station 21, the main machine clean water docking port 192 and the base station clean water docking port 23 are docked and communicated.

[0203] In the cleaning system provided by the embodiment of the present application, when the cleaning robot 10 docks at the cleaning base station 20 therein, the main machine sewage docking port 191 on the cleaning robot 10 can be docked and communicated with the base station sewage docking port 22 on the cleaning base station 20. Synchronously, the main machine clean water docking port 192 on the cleaning robot 10 can be docked and communicated with the base station clean water docking port 23 on the cleaning base station 20.
