DETAILED DESCRIPTION

[0063] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0064] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0065] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0066] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0067] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0068] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0069] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0070] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0071] Before describing in detail the cleaning system and connecting pipelines provided by the embodiments of the present disclosure, it is necessary to describe the related technologies as follows:

[0072] In related technologies, since the power cord, safety rope, liquid pipeline or gas pipeline on the window cleaning robot have different functions, each functional pipeline will be made separately using the process and material in its own field. For example: the safety rope needs to meet the high tensile strength requirements, and polyester yarn weaving process is mostly used. Water pipelines consider the requirements of anti-aging and corrosion resistance, and are mostly made of silicone material, which does not require high tensile strength. This will result in a large number of connecting pipelines between the window cleaning robot and the base station, which are easy to entangle with each other, affecting use and inconvenient to store.

[0073] In order to solve the above problems, the present disclosure provides a cleaning system, which may include a window cleaning robot, a base station and a connecting pipeline connecting the window cleaning robot and the base station, the connecting pipeline includes a tube body, the tube body includes a plurality of cavities isolated from each other, each cavity axially penetrates the tube body, at least one cavity is constructed as a cavity structure for fluid to pass through, and at least one cavity is constructed to accommodate a conductive wire, wherein the window cleaning robot and the base station are electrically connected through the conductive wire, and the fluid is transmitted through the cavity structure.

[0074] In this way, by improving the connecting pipeline between the window cleaning robot and the base station, a plurality of cavities are set on the pipe body of the connecting pipeline, at least one of which contains a conductive wire that can electrically connect the window cleaning robot and the base station, and at least one of which is a hollow structure, which can transmit fluid between the window cleaning robot and the base station. The fluid can be at least one of gas and liquid. In this way, the connecting pipeline can simultaneously have the functions of a power line, a liquid pipeline or a gas pipeline. Compared with the solution in the related art in which a power line, a liquid pipeline or a gas pipeline is separately set between the window cleaning robot and the base station in the cleaning system, the number of lines between the window cleaning robot and the base station can be reduced, and the problem of easy entanglement when the number of lines is large can be improved, thereby improving the convenience of use of the cleaning system and facilitating the storage of lines.

[0075] For ease of understanding, refer to Figures 1 to 17 , the specific structure and working principle of the cleaning system of the present invention are explained in detail in combination with an embodiment.

[0076] like Figure 1 As shown, the cleaning system provided by the present disclosure may include a window cleaning robot 10, a base station 20, and a connecting pipe 30 connecting the window cleaning robot 10 and the base station 20. The connecting pipe 30 may include a pipe body 31.

[0077] like Figures 2 to 4 As shown, the tube body 31 includes a plurality of cavities 310 isolated from each other, and each cavity 310 axially penetrates the tube body 31. Figure 5 As shown, at least one cavity 310 is constructed as a cavity structure through which fluid can pass, and at least one cavity 310 is constructed to accommodate a conductive wire 320, wherein the window cleaning robot 10 and the base station 20 are electrically connected through the conductive wire 320, and the fluid is transmitted through the cavity structure.

[0078] The cleaning system provided by the embodiment of the present disclosure improves the connecting pipeline 30 between the window cleaning robot 10 and the base station 20, and sets a plurality of cavities 310 on the pipe body 31 of the connecting pipeline 30. At least one of the cavities 310 contains a conductive wire 320 that can electrically connect the window cleaning robot 10 and the base station 20. At least one of the cavities 310 is a cavity structure, which can transmit fluid between the window cleaning robot 10 and the base station 20. The fluid can be at least one of gas and liquid. In this way, the connecting pipeline 30 can simultaneously have the functions of a power line, a safety rope, a liquid pipeline or a gas pipeline. Compared with the solution in the related art in which a power line, a liquid pipeline or a gas pipeline is separately set between the window cleaning robot 10 and the base station 20 in the cleaning system, the number of lines between the window cleaning robot 10 and the base station 20 can be reduced, and the problem that the lines are easily entangled when the number of lines is large can be improved, thereby improving the convenience of use of the cleaning system and facilitating the storage of the lines.

[0079] In one embodiment of the present disclosure, at least one cavity 310 may also be configured to contain an anti-drawing wire 330. In this way, the strength of the tube body 31 may be increased by burying the anti-drawing wire 330, so that the connecting pipeline 30 may also function as a safety rope. It should be noted that if the anti-drawing wire is not buried, the strength of the tube body 31 is sufficient, and the connecting pipeline 30 may also be used directly as a safety rope.

[0080] It should be noted that at least one cavity 310 is configured to accommodate the conductive wire 320. Here, it can be understood that at least one cavity 310 on the tube body 31 is a hollow channel, but the conductive wire 320 is accommodated therein. For ease of understanding, the cavity 310 configured to accommodate the conductive wire 320 is referred to as the first cavity 310a. When the first cavity 310a accommodates the conductive wire 320, the structure is as follows: Figure 5 As shown, the structure when the conductive wire 320 inside the first cavity 310a is removed is as follows Figures 2 to 4 shown.

[0081] like Figure 5 As shown, in some embodiments, the conductive wire 320 may include multiple conductors 3201 and an outer insulating layer 3202 wrapped around the multiple conductors 3201, and the outer insulating layer 3202 is tightly combined with the inner wall of the first cavity 310a to prevent the conductive wire 320 from shaking in the first cavity 310a, which is more conducive to extending the service life of the conductive wire 320. Of course, it can be understood that a certain gap can also be retained between the conductive wire 320 and the inner wall of the first cavity 310a.

[0082] like Figures 2 to 5 As shown, at least one cavity 310 is constructed as a cavity structure. It can be understood here that at least one cavity 310 on the tube body 31 can retain at least a cavity with a certain cross-sectional area. For ease of understanding, the cavity 310 constructed as a cavity structure will be referred to as the second cavity 310b below.

[0083] like Figures 2 to 5 As shown, at least one lumen 310 is configured to accommodate an anti-drawing wire 330. Here, it can be understood that at least one lumen 310 on the tube body 31 has a hollow channel structure, but contains an anti-drawing wire 330 inside. At least one lumen 310 is configured to accommodate an anti-drawing wire 330. In other words, the anti-drawing wire 330 is buried inside the tube body 31. The anti-drawing wire 330 here can be made of any suitable material with certain tensile properties, such as steel wire, glass fiber, etc. For ease of understanding, the lumen 310 configured to accommodate the anti-drawing wire 330 is referred to as the third lumen 310c below.

[0084] The window cleaning robot 10 is mainly used to perform cleaning actions. A functional unit may be provided on the window cleaning robot 10, and a walking unit may be provided at the bottom. The walking unit is used to drive the window cleaning robot 10 to walk. The functional unit may be of various types. For example, the functional unit may include a liquid spraying unit 11 for spraying cleaning liquid onto the surface of the object to be wiped or the cleaning cloth. The present invention does not limit the type of the functional unit.

[0085] A power module and a liquid supply unit may be provided in the base station 20. The power module is used to provide power to the window cleaning robot 10. The liquid supply unit 21 is used to supply cleaning liquid to the window cleaning robot 10. The present invention does not limit the specific structure of the base station 20.

[0087] In a specific embodiment, Figure 2 As shown, the number of the liquid supply channel A provided on the tube body 31 is one. It is understandable that the specific number of the liquid supply channel A on the tube body 31 is not limited to one.

[0089] In a specific embodiment, Figure 2 As shown, the number of the drainage channel B provided on the tube body 31 is one. It is understandable that the specific number of the drainage channel B on the tube body 31 is not limited to one.

[0090] In addition, in one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, at least one cavity 310 (ie, the second cavity 310 b ) constructed as a cavity structure serves as a gas cavity C, which is connected between the window cleaning robot 10 and the base station 20 , and is used to transport gas between the window cleaning robot 10 and the base station 20 .

[0091] In a specific embodiment, Figure 3 and Figure 4 As shown, the number of the gas cavity C provided on the tube body 31 is one. It is understandable that the specific number of the gas cavity C on the tube body 31 is not limited to one.

[0092] It should be noted that, in one embodiment of the present disclosure, the second cavity 310b on the tube body 31 may only include the liquid supply cavity A; Figures 2 to 5 As shown, the second cavity 310b on the tube body 31 may include a liquid supply cavity A, and at least one of a liquid discharge cavity B and a gas cavity C. It can be understood that the specific number and distribution position of the gas cavity C, the liquid supply cavity A and the liquid discharge cavity B are not limited to the embodiment shown in the figure.

[0093] In a specific embodiment of the present disclosure, a method for transmitting the cleaning liquid between the window cleaning robot 10 and the base station 20 through the connecting pipe 30 is as follows:

[0094] like Figure 1 As shown, a liquid supply unit 21 and a dirt storage unit 22 are provided on the base station 20, and a liquid spray unit 11 and a dirt collection unit 12 are provided on the window cleaning robot 10. The liquid supply unit 21, the liquid supply cavity A, and the liquid spray unit 11 are connected in sequence; the dirt collection unit 12, the liquid discharge cavity B, and the dirt storage unit 22 are connected in sequence.

[0095] In one embodiment of the present disclosure, a clean water pump 13 may be further provided on the window cleaning robot 10, and the clean water pump 13 is connected between the liquid spraying unit 11 and the liquid supply channel A; or, a clean water pump 13 may be further provided on the base station 20, and the clean water pump 13 is connected between the liquid supply unit 21 and the liquid supply channel A; or, clean water pumps 13 may be provided on the window cleaning robot 10 and the base station 20, respectively, and the clean water pump 13 on the window cleaning robot 10 is connected between the liquid spraying unit 11 and the liquid supply channel A, and the clean water pump 13 on the base station 20 is connected between the liquid supply unit 21 and the liquid supply channel A.

[0096] In one embodiment of the present disclosure, a sewage pump 14 may be further provided on the window cleaning robot 10, and the sewage pump 14 is connected between the dirt collection unit 12 and the drainage channel B; or, a sewage pump 14 may be further provided on the base station 20, and the sewage pump 14 is connected between the dirt storage unit 22 and the drainage channel B; or, sewage pumps 14 may be provided on the window cleaning robot 10 and the base station 20, respectively, and the sewage pump 14 on the window cleaning robot 10 is connected between the dirt collection unit 12 and the drainage channel B, and the sewage pump 14 on the base station 20 is connected between the dirt storage unit 22 and the drainage channel B.

[0097] The method of realizing gas transmission between the window cleaning robot 10 and the base station 20 through the connecting pipeline 30 can be as follows:

[0098] In one embodiment of the present disclosure, the base station 20 is provided with a negative pressure unit (not shown in the figure), which may include a negative pressure fan, etc. The window cleaning robot 10 may include a negative pressure inner cavity (not shown in the figure), and the negative pressure unit, the gas cavity C and the negative pressure inner cavity are sequentially connected, so that the window cleaning robot 10 is adsorbed on the surface of the object to be cleaned under the action of negative pressure.

[0100] In addition, in one embodiment of the present disclosure, the conductive wire 320 can be used as a power line, connected between the window cleaning robot 10 and the base station 20, so that by turning on the power switch of the base station 20, electric energy can be supplied to the window cleaning robot 10 through the conductive wire 320.

[0101] It should be noted that the conductive wire 320 can also be used as other signal wires in addition to the power wire. For example, the base station 20 can also send instructions to the window cleaning robot 10 through the conductive wire 320 to control the window cleaning robot 10 to perform corresponding actions.

[0102] In one embodiment of the present disclosure, Figure 7 As shown, the radial cross-sectional area of ​​the liquid discharge channel B is larger than the radial cross-sectional area of ​​the liquid supply channel A. In this way, it can be avoided that the liquid discharge channel B is blocked by dirt and cannot be discharged in time during the cleaning operation of the window cleaning robot 10.

[0103] In one embodiment of the present disclosure, the radial cross-sectional area of ​​the liquid supply channel A may range from 1 to 25 square millimeters, and the radial cross-sectional area of ​​the liquid discharge channel B may range from 1 to 30 square millimeters. In practical applications, the inner diameter of the liquid supply channel A may be reasonably selected based on parameters such as the liquid flow rate and liquid pressure of the cleaning liquid required by the cleaning system.

[0104] In one embodiment of the present disclosure, the radial cross-sectional area of ​​the gas cavity C may range from 1 to 50 square millimeters. The specific value of the radial cross-sectional area of ​​the gas cavity C may be reasonably selected according to the actual application scenario of the cleaning system.

[0105] In one embodiment of the present disclosure, the radial cross-sectional area of ​​the conductive wire 320 may range from 1 to 50 square millimeters. Correspondingly, the radial cross-sectional area of ​​the first cavity 310a may range from 1 to 50 square millimeters.

[0106] Since the connecting pipeline 30 takes into account the functions of a safety rope, a power cord, and a fluid pipeline, the connecting pipeline 30 must meet the tensile performance requirements when used as a safety rope. When the connecting pipeline 30 is used as a fluid pipeline, it needs to have a certain strength to meet the pressure resistance requirements and is not easy to bend. At the same time, the connecting pipeline 30 must have a certain flexibility to facilitate use and storage. Therefore, in one embodiment of the present disclosure, the sum of the radial cross-sectional areas of all cavities 310 on the tube body 31 accounts for 10 to 50% of the radial cross-sectional area of ​​the tube body 31. In this way, the tube body 31 can simultaneously meet the requirements of high tensile resistance, pressure resistance and flexibility.

[0107] In another embodiment of the present disclosure, the tube body 31 can be made of any one or more insulating materials such as thermoplastic polyurethane elastomer (TPU), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), and silicone.

[0108] In one embodiment of the present disclosure, Figure 2 As shown, any two cavities 310 are isolated from each other, so that the fluid in each cavity 310, the conductive wire 320 and the anti-drawing wire 330 are guaranteed not to affect each other.

[0109] In one embodiment of the present disclosure, Figure 5 As shown, the conductive wire 320 and the anti-drawing wire 330 are accommodated in the same cavity 310, and the anti-drawing wire 330 is clamped between the conductive wire 320 and the inner wall of the cavity 310. In this way, the anti-drawing wire 330 can be clamped and fixed, and buried in the tube body 31.

[0110] In another embodiment of the present disclosure, Figure 6 As shown, the conductive wire 320 and the anti-drawing wire 330 are respectively accommodated in different cavities 310. The tube body 31 can be formed by a plastic forming process, and the conductive wire 320 and the anti-drawing wire 330 can be directly formed on the tube body 31 during the plastic forming process of the tube body 31.

[0111] In one embodiment of the present disclosure, Figure 5 As shown, when there is only one second cavity 310b, the second cavity 310b can be located on one side of the first cavity 310a in the radial direction of the tube body 31; when there are at least two second cavities 310b, at least two second cavities 310b can be distributed circumferentially around the first cavity 310a, and the portion between the cavities 310 on the tube body 31 forms an insulating layer 340.

[0112] In one embodiment of the present disclosure, Figure 5As shown, the contour line of the radial section of the second cavity 310b includes a first line segment a and a second line segment b extending roughly along the circumferential direction of the first cavity 310a; along the radial direction of the tube body 31, the first line segment a is closer to the first cavity 310a than the second line segment b; the first line segment a and the second line segment b are both arc-shaped line segments, the first line segment a is concentric with the contour line of the radial section of the first cavity 310a, and the second line segment b is concentric with the contour line of the radial section of the tube body 31.

[0113] It should be noted here that the first line segment a and the second line segment b extend approximately along the circumferential direction of the first cavity 310a, which means that the arc bending direction of the first line segment a and the second line segment b is approximately the same as the bending direction of the circumferential edge of the first cavity 310a close to the second cavity 310b.

[0114] With the above solution, the first line segment a is concentric with the contour line of the radial section of the first cavity 310a, so that in the arc direction along the first line segment a, the thickness d1 of the insulating layer 340 between the first cavity 310a and the second cavity 310b is approximately equal everywhere; the second line segment b is concentric with the contour line of the radial section of the tube body 31, so that in the arc direction along the first line segment a, the thickness d2 of the insulating layer 340 between the second cavity 310b and the first tube body 31 is approximately equal everywhere. In this way, the thickness of the insulating layer 340 on the tube body 31 can be ensured to be as uniform as possible, so as to improve the overall performance of the tube body 31.

[0115] In one embodiment of the present disclosure, Figure 5 As shown, when the tube body 31 includes at least two second cavities 310b, the at least two second cavities 310b are arranged at intervals along the circumferential direction of the first cavity 310a, and the contour line of the radial section of each second cavity 310b also includes a third line segment c adjacent to another second cavity 310b, and the third line segments c of two adjacent second cavities 310b are parallel to each other. In this way, the thickness of the insulating layer 340 between two adjacent second cavities 310b can be uniform, so as to improve the compressive resistance and other properties of the tube body 31.

[0116] In one embodiment of the present disclosure, there is a smooth transition between the first line segment a, the second line segment b and the third line segment c, the molding process of the tube body 31 is easier to implement, and stress concentration can be reduced to increase the service life of the tube body 31, and dead corners can be reduced to avoid dirt accumulation.

[0117] In one embodiment of the present disclosure, the thickness of the insulating layer 340 ranges from 0.5 to 2.5 mm. This arrangement can ensure that the insulating layer 340 is not easily broken and meet the performance requirements of the tube body 31 such as compression resistance, tension resistance and flexibility.

[0118] In one embodiment of the present disclosure, Figure 1As shown, the connecting pipeline 30 also includes: a conversion joint 32 , one axial end of the tube body 31 is connected to the window cleaning robot 10 through the conversion joint 32 , and the other axial end of the tube body 31 is connected to the base station 20 through the conversion joint 32 .

[0119] In the above scheme, the radial cross-section shape of the second cavity 310b constructed as a hollow structure is irregular, and the tube body 31 cannot be directly connected to the liquid pipeline of the window cleaning robot 10 and the base station 20. The main function of the conversion joint 32 is to convert the cavity 310 with an irregular cross-section in the tube body 31 into a universal joint with predetermined specifications, so as to realize the water connection between the connecting pipeline 30 and the window cleaning robot 10 and the base station 20.

[0120] In one embodiment of the present disclosure, Fig.11 As shown, the conversion joint 32 includes: a main body 321, a first plug-in tube 322 and a second plug-in tube 323, the main body 321 includes a plurality of axial holes 3211 axially passing through the main body 321, and each axial hole 3211 corresponds to a cavity 310; the first plug-in tube 322 is connected to the axial first end of the main body 321, and is configured to adapt to the cavity 310 and be inserted into the cavity 310; the second plug-in tube 323 is connected to the axial second end of the main body 321, and is configured to be different from the first plug-in tube 322, and the second plug-in tube 323 has a shape and size of predetermined specifications; wherein the second plug-in tube 323 is connected to the first plug-in tube 322 via the corresponding axial hole 3211 to form a channel.

[0121] In the above solution, there can be multiple first plug-in tubes 322, one first plug-in tube 322 corresponds to one cavity 310, and the cross-sectional shape of the first plug-in tube 322 is adapted to the cross-sectional shape of the corresponding cavity 310. Fig.10 and Fig.11 As shown in the example, the first plug-in tube 322 corresponding to the second cavity 310b can be a special-shaped cross-section and inserted into the cavity structure. The first plug-in tube 322 corresponding to the first cavity 310a can be a circular cross-section and inserted between the first cavity 310a and the conductive wire 320. The second plug-in tube 323 is configured to have a shape and size of predetermined specifications, that is, the second plug-in tube 323 can be a universal connector that meets the specification standards. The first plug-in tube 322 and the second plug-in tube 323 are connected through the corresponding axial hole 3211 to form a channel, and the fluid and the conductive wire 320 can pass through the corresponding channel. In this way, the conversion joint 32 realizes the conversion of the cavity 310 with a special cross-section on the tube body 31 into the second plug-in tube 323 that meets the specification standards. In one embodiment, when at least one cavity 310 is also configured to accommodate a tensile wire 330, the tensile wire 330 can be configured to pass through the corresponding channel.

[0122] In one embodiment of the present disclosure, Fig.11 As shown, the conversion joint 32 is provided with three first plug-in tubes 322, one of which can be inserted into the liquid supply channel A, another first plug-in tube 322 can be inserted into the liquid discharge channel B, and another can be inserted into the first channel 310a. It can be understood that the specific number of the first plug-in tubes 322 is not limited, and the first plug-in tubes 322 can be the same as the number of the channels 310, and the two correspond one to one. The second plug-in tubes 323 can correspond one to one with the first plug-in tubes 322.

[0123] In addition, in other embodiments of the present disclosure, Fig.11 As shown, the conductive wire 320 partially extends out of the corresponding cavity 310, or can be directly inserted into the corresponding axial hole 3211. With the above solution, for the conductive wire 320 in the tube body 31, when it is tightly fitted with the inner wall of the cavity 310, the conversion joint 32 may no longer be separately provided with the first plug-in tube 322 corresponding to the first cavity 310a, but the conductive wire 320 is directly passed through the axial hole 3211 on the main body 321, and is electrically connected to the base station 20 after being led out from the axial hole 3211. Similarly, for the case where the anti-drawing wire 330 is buried in the tube body 31, when the anti-drawing wire 330 is tightly fitted with the inner wall of the cavity 310, the conversion joint 32 may no longer be separately provided with a plug-in tube, and the anti-drawing wire 330 can be directly inserted into the corresponding axial hole 3211 on the main body 321 and fixed.

[0124] In one embodiment of the present disclosure, Fig.12 As shown, the conversion joint 32 may also include: an elastic sleeve 324 and a clamp ring 325, the elastic sleeve 324 is sleeved on the outer periphery of the tube body 31, one axial end of the elastic sleeve 324 is connected to the axial first end of the main body 321, and the other axial end of the elastic sleeve 324 is provided with a plurality of notches 3240 spaced apart along the circumferential direction, and the notches 3240 penetrate the elastic sleeve 324 in the radial direction, so that the end of the elastic sleeve 324 forms a deformable area at the position of the notches 3240; the clamp ring 325 is arranged outside the deformable area, and the deformable area can be pressed to deform by the radial clamping force, so that the elastic sleeve 324 clamps the tube body 31. In this way, the connection reliability between the tube body 31 and the conversion joint 32 can be further ensured.

[0125] In one embodiment of the present disclosure, the elastic sleeve 324 can be connected to the main body 321, and the inner diameter of the clamp ring 325 can be movably adjusted to facilitate the disassembly of the conversion joint 32. The specific structure of the clamp ring 325 can be selected from known products in the relevant technology, which will not be repeated here.

[0126] In addition, in one embodiment of the present disclosure, Figures 12 to 15As shown, the main body 321, the first plug-in tube 322 and the second plug-in tube 323 are connected as an integral structure, namely the third component 32D. That is to say, the conversion joint 32 can be integrally formed, and the material of the conversion joint 32 can be selected from plastic materials.

[0127] In one embodiment of the present disclosure, Figures 12 to 17 As shown, since plastic material has lower hardness than metal material, when plastic material is used to make the conversion joint 32, in order to ensure the reliability of the connection between the first plug-in tube 322 and the tube body 31, the conversion joint 32 may include an elastic sleeve 324 and a clamp ring 325, wherein the elastic sleeve 324 may be integrally formed with the main body 321, the first plug-in tube 322 and the second plug-in tube 323.

[0128] In one embodiment of the present disclosure, the conversion joint 32 can also be made of metal material. Figures 8 to 11 As shown, the conversion joint 32 includes two components that can be detachably connected. One of the components is a first component 32A, which includes a first main body part 326 and a first plug-in tube 322 integrally connected to the first main body part 326; the other component is a second component 32B, which may include a second main body part 327 and a second plug-in tube 323 integrally connected to the second main body part 327; the first main body part 326 and the second main body part 327 are respectively provided with a plurality of sub-axial holes 32a that penetrate axially, and the first main body part 326 and the second main body part 327 cooperate to form a main body 321, and the sub-axial holes 32a on the first main body part 326 and the sub-axial holes 32a on the second main body part 327 are connected in a one-to-one correspondence, forming an axial hole 3211 on the main body 321; and one of the first main body part 326 and the second main body part 327 is provided with a third plug-in tube 328, and the third plug-in tube 328 is inserted into the sub-axial hole 32a of the other. Fig.11 In the illustrated embodiment, the third plug-in tube 328 is integrally connected to the second main body portion 327 .

[0129] In addition, if Fig.11 As shown, in one embodiment of the present disclosure, a sealing gasket 32C may be sandwiched between the first body portion 326 and the second body portion 327 to prevent leakage. Specifically, the sealing gasket 32C may be provided with a plurality of through holes 3214, and the plurality of through holes 3214 correspond to the plurality of sub-axial holes 32a one by one.

[0130] In addition, if Fig.11 As shown, in one embodiment of the present disclosure, connecting holes 3213 may be respectively provided on the first main body portion 326, the sealing gasket 32C and the second main body portion 327, and fasteners may be installed in the connecting holes 3213 to detachably connect the first main body portion 326, the sealing gasket 32C and the second main body portion 327.

[0131] It should be understood that the connection method between the first body portion 326 and the second body portion 327 is not limited thereto.

[0132] In one embodiment of the present disclosure, Fig.11 As shown, at least one cavity is also configured to accommodate an anti-drawing wire 330, which partially extends out of the corresponding cavity 310 and is inserted into the first axial hole 3211 among the plurality of axial holes 3211; the main body 321 is also provided with a radial hole 3212, which radially penetrates the outer wall of the main body 321 and the first axial hole 3211', wherein the anti-drawing wire 330 is led to the outside of the main body 321 through the radial hole 3212 and is fixed to the main body 321. With the above solution, after the anti-drawing wire 330 is led out of the radial hole 3212, any suitable fixing member such as a fixing block and a fixing ring is used to fix the anti-drawing wire 330.

[0133] It should be noted that the weight of the base station 20 is significantly greater than that of the window cleaning robot 10, so the anti-tensile wire 330 can be directly fixed on the conversion joint 32. During the use of the cleaning system, even if the window cleaning robot 10 falls, it is not easy to pull the base station 20 to move, and the equipment operation is safe.

[0134] For a cleaning system in which the window cleaning robot 10 is heavier, in order to ensure the safe operation of the equipment, the anti-tensile wire 330 can be configured to have a connecting piece at one end extending from the radial hole 3212, and the connecting piece can be connected to an external object, so that when the window cleaning robot 10 falls, the window cleaning robot 10 can be pulled by the external object to ensure the safe operation of the equipment.

[0135] In one embodiment of the present disclosure, Fig. 9 and 11 As shown, the first axial hole 3211 ′ includes a first port and a second port axially opposite to each other. The first port is the insertion end of the anti-drawing wire 330 , and a notch 3215 is provided on the circumferential edge of the second port. The notch 3215 is axially connected to the radial hole 3212 along the main body 321 .

[0136] By adopting the above scheme, by setting a notch 3215 on the circumferential edge of the second port, when the tube body 31 and the conversion joint 32 are assembled, the notch 3215 can expose a part of the radial hole 3212 from the end face of the second port. Therefore, the anti-drawing wire 330 can be passed through the first axial hole 3211', and then passed into the radial hole 3212 through the exposed position of the radial hole 3212, thereby making the fixing operation of the anti-drawing wire 330 more convenient.

[0137] It should be noted here that Fig. 9 and Fig.11As shown in the example, when the conversion joint includes a first component and a second component, the notch 3215 can be located at the port of the sub-axial hole on the first main body part 326, that is, the notch 3215 is located on the end face of the first main body part 326 facing the second main body part 327, so that the notch 3215 can be blocked by the second main body part 327 and the sealing gasket 32C to avoid being exposed to the outside world all the time.

[0138] In addition, a connecting pipeline 30 is also provided in the embodiment of the present disclosure, which is used to connect the base station 20 of the cleaning system and the window cleaning robot 10; the connecting pipeline 30 includes: a tube body 31, the tube body 31 includes a plurality of cavities 310 isolated from each other, each cavity 310 axially penetrates the tube body 31, at least one cavity 310 is constructed as a cavity structure for fluid to pass through, at least one cavity 310 is constructed to accommodate a conductive wire 320, and at least one cavity 310 is constructed to accommodate an anti-tensile wire 330, wherein the window cleaning robot 10 and the base station 20 are electrically connected through the conductive wire 320, and the fluid is transmitted through the cavity structure.

[0139] The specific structure and connection relationship of the connecting pipeline 30 are described in detail above, and the present disclosure will not repeat them here. The connecting pipeline 30 of the present disclosure can be applied not only to the above-mentioned cleaning system, but also to other equipment that needs to be cleaned, and the present disclosure will not list them one by one here.

[0140] Application Scenario

[0141] refer to Figure 1 , Figure 6 and Figure 7 In a cleaning system provided in one embodiment of the present disclosure, two ends of a pipe body 31 in a connecting pipe 30 are connected to a window cleaning robot 10 and a base station 20 respectively through conversion joints 32, wherein a liquid supply channel A in the pipe body 31 connects a liquid spraying unit 11 in the window cleaning robot 10 and a liquid supply unit 21 on the base station 20, a liquid discharge channel B in the pipe body 31 connects a dirt collection unit 12 in the window cleaning robot 10 and a dirt storage unit 22 on the base station 20, and a conductive wire 320 in the pipe body 31 electrically connects the window cleaning robot 10 and the base station 20. When the cleaning system is used, the window cleaning robot 10 can be adsorbed on the glass, and the base station 20 can be placed indoors. When the base station 20 is switched on, it can supply electric energy to the window cleaning robot 10 through the connecting pipe 30. The liquid supply unit 21 on the base station 20 starts to supply cleaning liquid to the window cleaning robot 10 through the liquid supply cavity A. The window cleaning robot 10 sprays the cleaning liquid onto the surface of the object to be cleaned or the cleaning cloth through the liquid spraying unit 11. The dirt generated during the cleaning process can be discharged to the dirt storage unit 22 of the base station 20 through the liquid discharge cavity B. When the window cleaning robot 10 is separated from the surface of the object to be cleaned, the connecting pipe 30 can effectively prevent the window cleaning robot 10 from falling because the anti-drawing wire 330 is embedded inside.

[0142] The cleaning system disclosed in the present invention improves the connecting pipeline 30 between the window cleaning robot 10 and the base station 20, and sets a plurality of cavities 310 on the pipe body 31 of the connecting pipeline 30. At least one of the cavities 310 contains a conductive wire 320 that can electrically connect the window cleaning robot 10 and the base station 20. At least one of the cavities 310 contains a tensile wire 330, which can improve the strength of the pipe body 31. At least one of the cavities 310 is a hollow structure, which can transmit fluid between the window cleaning robot 10 and the base station 20. In this way, the connecting pipeline 30 can simultaneously have the functions of a power line, a safety rope, and a liquid pipeline. Compared with the solution in the related art in which a power line, a safety rope, and a liquid pipeline are separately set between the window cleaning robot 10 and the base station 20 in the cleaning system, the number of lines between the window cleaning robot 10 and the base station 20 can be reduced, and the problem that the lines are easily entangled when the number of lines is large can be improved, thereby improving the convenience of use of the cleaning system and facilitating the storage of the lines.

[0143] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings.

[0144] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.

The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
