[0003] This application provides a pipeline docking device, a base station, a cleaning equipment, and a cleaning system, which can improve the docking accuracy between the first interface in the pipeline docking device and the equipment pipeline on the cleaning equipment.

[0012] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0013] The cleaning robot is equipped with a water nozzle that can connect to the water interface in the base station, enabling water connection between the base station and the cleaning robot, and facilitating automatic water filling and sewage discharge. However, in related technologies, during the docking process with the base station, the cleaning robot is in motion, and its position on the base station may deviate slightly. This can lead to misalignment between the robot's water nozzle and the base station's pipe interface, resulting in inaccurate docking. Furthermore, it can cause unstable water connections, affecting the efficiency of water filling or sewage discharge. Alternatively, incomplete docking may require the cleaning robot to retract for a second docking, impacting its deployment efficiency. Moreover, if the robot fails to detect the misalignment and forces docking, it can damage the water nozzle or the pipe. Additionally, the docking devices in related technologies suffer from complex structures and unstable docking, requiring urgent improvement.

[0014] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-3 This application proposes a pipeline connection device 1, which is applied to a base station (not shown in the figure) of a cleaning system. The cleaning system includes cleaning equipment and a base station (not shown in the figure). The cleaning equipment has equipment pipelines. The pipeline connection device 1 includes a support 10 and a connecting pipe 20. The connecting pipe 20 is used to connect the waterway structure between the cleaning equipment and the base station.

[0015] The bracket 10 is installed on the base station; the connecting pipe 20 has at least a first interface 211, and the connecting pipe 20 is connected to the equipment pipeline through the first interface 211. The connecting pipe 20 is rotatably installed on the bracket 10 around the first axis M to change the position of the first interface 211 relative to the bracket 10.

[0016] It is understood that the connecting pipe 20 can rotate relative to the bracket 10, thereby adjusting the position of the first interface 211. This allows for adaptive adjustment of the position of the first interface 211 by rotating the connecting pipe 20 during the docking of the cleaning equipment and the pipeline docking device 1, thus compensating for positional deviations during the docking process and improving the docking success rate and stability. In some embodiments, the bracket 10 has a rotating shaft 11, the axis of which is the first axis M. The connecting pipe 20 is rotatably connected to the bracket 10 via the rotating shaft 11, allowing the connecting pipe 20 to rotate relative to the bracket 10 around the first axis, thereby changing the position of the first interface 211 relative to the bracket 10.

[0017] The axial extension direction of the first interface 211 intersects the direction of the first axis M. That is, the angle between the axial extension direction of the first interface 211 and the direction of the first axis M can be set as an acute angle, a right angle or an obtuse angle. The specific angle can be set according to the actual situation. Preferably, the axial extension direction of the first interface 211 is perpendicular to the first axis M.

[0018] Specifically, the cleaning equipment can be a cleaning robot. The cleaning robot's equipment pipeline has a water nozzle, and the base station has a seat for the cleaning robot to be stably placed. During the docking process between the cleaning robot and the base station, when the cleaning robot returns to the seat on the base station, the cleaning robot's water nozzle first contacts the first interface 211 of the connecting pipe 20 to begin docking. At the same time, the cleaning robot continues to sit on the seat until it is in the seat, at which point the water nozzle and the connecting pipe 20 are docked. During the process from the cleaning robot returning to the base station to completing the seating, the cleaning robot may undergo movements such as moving forward, lifting, and lowering on the base station. Therefore, the position of the first interface 211 of the connecting pipe 20 will change slightly as the cleaning robot moves.

[0019] It should be noted that, in this embodiment, a rotatable connecting pipe 20 is provided, allowing the cleaning equipment to rotate when docking with the base station. This enables the first interface 211 on the connecting pipe 20 to float and adjust according to the position changes of the pipe opening on the cleaning equipment. In other words, the rotation design of the connecting pipe 20 effectively adapts to changes in the position of the pipe opening, ensuring accurate docking of the first interface 211 with the equipment pipe. It can be understood that this application changes the position of the first interface by rotating the connecting pipe around the first axis, resulting in a large float and tolerance of the first interface. This improves the docking success rate, reduces docking errors caused by height or position differences, increases the docking success rate, reduces the probability of jamming, and decreases the frequency of secondary docking due to inaccurate docking. Consequently, it improves the efficiency of water filling and sewage discharge between the cleaning equipment and the base station.

[0020] In some embodiments, the connecting pipe rotates passively. For example, during the docking process between the cleaning equipment and the base station, the housing structure or equipment pipeline on the cleaning equipment aligns with the first interface. At this time, the cleaning equipment can apply a force to the connecting pipe, causing it to rotate around the first axis, thereby changing the position of the first interface and achieving successful docking between the first interface and the equipment pipeline. Alternatively, a rotation drive mechanism, such as a motor, can be provided on the base station to drive the connecting pipe to rotate actively, thereby achieving successful docking between the first interface and the equipment pipeline.

[0021] Please see Figure 3 In some embodiments of this application, the first axis M is parallel to the horizontal direction, that is, the first axis M extends in the horizontal direction, so that when the connecting pipe 20 rotates, the position of the first interface 211 on the connecting pipe 20 can be flexibly adjusted in the vertical direction. Therefore, the connecting pipe 20 can rotate around the horizontal axis, so that the height of the first interface 211 on the connecting pipe 20 can float up and down to adapt to the pipe openings of equipment pipelines of different heights.

[0022] In some embodiments of this application, the connecting pipe 20 has a first rotational surface (not shown in the figure) perpendicular to the first axis M, and the angle between the axial extension direction of the first interface 211 and the first rotational surface is less than or equal to 5 degrees. For example, a reference point is selected on the first interface 211, and a first vertical line perpendicular to the first axis M is formed through this reference point. When the connecting pipe 20 rotates around the first axis M, the first vertical line also rotates around the first axis M. At this time, the rotation path of the first vertical line is on the same plane, which is the first rotational surface.

[0023] It is understandable that the axial extension direction of the first interface 211 can be located on the first rotating surface, or it can form an angle of less than or equal to 5 degrees with the first rotating surface. This setting allows the axial direction of the first interface 211 to remain basically consistent with the first rotating surface when the connecting pipe 20 rotates, thereby reducing the docking resistance caused by angular deviation during the docking process and improving the smoothness and accuracy of the docking. The specific setting angle of the connecting pipe 20 can be selected according to the actual situation.

[0024] Please see Figures 2-3 In some embodiments of this application, the connecting pipe 20 includes a rotating part 23, a first pipe segment 21, and a second pipe segment 22. The rotating part 23 is rotatably disposed on the bracket 10 about a first axis M. The first pipe segment 21 is disposed on the rotating part 23 and has a first interface 211. The second pipe segment 22 is disposed on the rotating part 23 and communicates with the first pipe segment 21. The second pipe segment 22 has a second interface 221. The connecting pipe 20 is connected to the base station through the second interface 221.

[0025] Specifically, the rotating part 23 is located between the first pipe section 21 and the second pipe section 22. The rotating part 23 cooperates with the rotating shaft 11 on the bracket 10 through a bearing to ensure that the connecting pipe rotates flexibly and reduce frictional resistance. When the connecting pipe 20 rotates, the positions of the first interface 211 and the second interface 221 will change. The base station is equipped with a water tank or water trough, etc. The second interface 221 can be connected to the water tank or water trough through a flexible pipe. The design of the flexible pipe can enhance the flexibility of the connection, so that the flexible pipe can buffer displacement during the rotation of the connecting pipe 20 and maintain the connection stability between the second interface 221 and the water tank or water trough, thereby ensuring smooth and unobstructed water connection.

[0026] Furthermore, in some embodiments of this application, the extension direction of the first pipe segment 21 is perpendicular to the first axis M, thereby making the vertical floating of the first interface 211 more stable, while ensuring that the axial direction of the first interface 211 always maintains good alignment with the docking equipment pipeline during the rotation of the connecting pipe 20. This structural design not only helps to improve docking efficiency, but also reduces the risk of leakage caused by pipeline vibration or misalignment, further optimizing the water connection performance between the cleaning equipment and the base station.

[0027] Furthermore, in some embodiments of this application, the extension direction of the second pipe segment 22 forms an angle α with the first axis M, wherein the angle α satisfies 0 < α ≤ 45 degrees. Specifically, the design of the angle α makes the connecting pipe 20 more flexible when rotating, and makes the overall structure of the pipe docking device 1 more compact, which facilitates the installation of the pipe docking device 1 in a small space and reduces the space occupied.

[0028] Please see Figure 2In some embodiments of this application, a first limiting structure 41 is provided on the rotating part 23, and a second limiting structure 42 is provided on the bracket 10. The cooperation of the first limiting structure 41 and the second limiting structure 42 is used to make the connecting pipe 20 have an upper stop point and a lower stop point of rotation.

[0029] Specifically, the connecting pipe 20 has an upper and lower limit point on its rotation path. When the connecting pipe 20 rotates to the upper and lower limit points, the first limiting structure 41 abuts against the second limiting structure 42 on the bracket 10 to restrict the connecting pipe 20 from continuing to rotate. The first limiting structure 41 and the second limiting structure 42 limit the rotation range of the connecting pipe 20, preventing excessive rotation that could lead to connection failure between the connecting pipe 20 and the equipment pipeline. The design of the first limiting structure 41 and the second limiting structure 42 allows for position adjustment according to actual needs, ensuring that the rotation angle of the connecting pipe 20 is finely adjusted within a reasonable range, thereby improving connection accuracy and sealing reliability.

[0030] The first limiting structure 41 can be a baffle, and the second limiting structure 42 can be an abutment. The baffle is disposed on the outer periphery of the rotating part 23, and the abutment is fixed on the bracket 10. When the connecting pipe 20 rotates to the upper or lower stop point, the baffle contacts the abutment and generates a limiting effect.

[0031] In some embodiments, such as Figure 2 As shown, there are two first limiting structures 41, namely a first limiting member 411 and a second limiting member 412. The first limiting member 411 and the second limiting member 412 are disposed on the rotating part 23 of the connecting pipe 20 and are respectively located on the upper and lower sides of the rotating part 23. When the connecting pipe 20 rotates to the upper stop point, the first limiting member 411 abuts against the upper side of the second limiting structure 42 in the bracket 10; when the connecting pipe 20 rotates to the lower stop point, the second limiting member 412 abuts against the lower side of the second limiting structure 42 in the bracket 10. This ensures that the position of the connecting pipe 20 can be limited at both the upper and lower stop points, effectively preventing the connection failure caused by excessive rotation of the connecting pipe 20.

[0032] Furthermore, when the connecting pipe 20 rotates from the top dead center to the bottom dead center, the vertical movement distance of the first interface 211 is d1. d1 can satisfy 2mm≤d1≤8mm. By reasonably setting the movement distance d1 of the first interface 211, it is ensured that the movement distance d1 of the first interface 211 is within a reasonable range during the rotation of the connecting pipe 20. This ensures that the equipment pipeline can be inserted smoothly without affecting the docking effect due to the excessive movement distance d1 of the first interface 211.

[0033] Please see Figures 3-4In some embodiments of this application, the bracket 10 includes a bracket housing 12, the bracket housing 12 having a mounting chamber 124, the rotating part 23 being rotatably disposed in the mounting chamber 124, and at least a portion of the first pipe section 21 being located outside the mounting chamber 124; the pipe connection device 1 also includes a shielding member 50, the shielding member 50 being sleeved on the first pipe section 21 and located between the first interface 211 and the bracket housing 12.

[0034] Specifically, the bracket housing 12 can be a hollow structure, forming an installation chamber 124 inside to accommodate the rotating part 23 of the connecting pipe 20. Therefore, the bracket housing 12 can provide good support and protection for the rotating part of the connecting pipe 20, while also preventing interference from the external environment to the rotating part 23. The bracket housing 12 is also provided with a through hole 123. The first pipe section 21 of the connecting pipe 20 extends out of the installation chamber 124 through the through hole 123. The shielding member 50 is sleeved on the first pipe section 21 and is located between the first interface 211 and the bracket housing 12. Therefore, the shielding member 50 can block the through hole 123 on the bracket housing 12, preventing dust and impurities from entering the installation chamber 124 through the through hole 123, ensuring the cleanliness of the inside of the bracket housing 12, which is conducive to the long-term stable operation of the connecting pipe 20.

[0035] In some embodiments, the bracket housing 12 may include a first housing 121 and a second housing 122. The first housing 121 and the second housing 122 are connected by snap-fit ​​or thread for easy disassembly and maintenance. The first housing 121 and the second housing 122 together form an installation chamber 124 and a pipeline channel communicating with the installation chamber 124. A through hole 123 is provided on the first housing 121, and a rotating shaft 11 is disposed on the second housing 122 and located in the installation chamber 124. The first section 21 of the connecting pipe 20 extends out of the installation chamber 124 through the through hole 123, and the second section 22 of the connecting pipe 20 extends to the outside of the installation chamber 124 through the pipeline channel.

[0036] The shielding member 50 is spaced apart from the support housing 12 so that there is a gap between the shielding member 50 and the support housing 12. This can prevent the shielding member 50 from being directly hit and damaged by the impact force of the cleaning equipment when it is connected to the pipeline connection device 1.

[0037] In some embodiments of this application, the shielding member 50 is an elastic member. When the cleaning equipment is moving and docking, the equipment pipeline docks with the first interface 211 of the first pipe section 21. The shielding part 34 can fit with the opening of the equipment pipeline. When the shielding member 50 is subjected to external force, it can undergo elastic deformation to provide a buffer for the equipment pipeline, prevent the equipment pipeline from directly contacting the support housing 12 and causing an impact, and help improve the stability of the docking process.

[0038] Please see Figures 3-4In some embodiments of this application, the pipeline docking device 1 further includes a sealing element 30, which is sleeved on the connecting pipe 20 and located at one end of the connecting pipe 20 near the first interface 211. The sealing element 30 is used to seal between the first interface 211 and the equipment pipeline when the first interface 211 is docked with the equipment pipeline.

[0039] Understandably, the seal 30 effectively prevents liquid leakage during the docking process, improves the sealing performance of the pipeline docking device 1, and ensures the safety and reliability of the docking process. The seal 30 can be made of materials such as rubber or silicone, possessing good elasticity and sealing properties; the connecting pipe 20 can be made of a high-strength hard plastic material to improve its durability and stability, ensuring that the connecting pipe 20 does not deform during long-term use.

[0040] In some embodiments, such as Figures 3-4 As shown, a snap-fit ​​portion 212 is provided on the outer periphery of the first pipe section 21 of the connecting pipe 20, and a snap-fit ​​groove 31 is provided on the inner wall of the sealing element 30. The snap-fit ​​portion 212 snaps into the snap-fit ​​groove 31. It is easy to understand that the cooperation between the snap-fit ​​portion 212 and the snap-fit ​​groove 31 helps to improve the connection between the sealing element 30 and the first pipe section 21, prevents the sealing element 30 from shifting during docking or sealing, and further ensures the sealing effect.

[0041] Further reading is available upon request. Figures 3-4 In some embodiments of this application, the sealing element 30 includes a main body 32 and a sealing ring 33 disposed on the main body. The main body 32 is sleeved on the first pipe section 21, and the first interface protrudes from the main body along the direction of the first axis.

[0042] Specifically, when the main body 32 is fitted onto the first pipe section 21, the main body 32 and the first pipe section 21 are interference-fitted. The main body 32 undergoes elastic deformation, allowing its inner ring to tightly fit against the outer wall of the first pipe section 21. This enhances the sealing effect between the main body 32 and the first pipe section 21, preventing liquid leakage between them. Simultaneously, a sealing ring 33 is fitted onto the main body 32. The inner ring of the sealing ring 33 is sealed to the main body 32, while its outer ring abuts against the inner wall of the equipment pipeline. When the outer ring of the sealing ring 33 abuts against the inner wall of the equipment pipeline, it also undergoes elastic deformation, ensuring a tight fit between the sealing ring 33 and the inner wall of the equipment pipeline. This effectively prevents liquid leakage, improves overall sealing performance, and ensures the safety and stability of the pipeline connection. The main body 32 and the sealing ring 33 are designed as an integrated unit, ensuring the stability of the sealing ring 33 and improving the sealing effect.

[0043] It should be noted that the first interface 211 protrudes from the main body 32 along the direction of the first axis M. That is, the first interface 211 of the connecting pipe 20 passes through the seal 30 and extends out of the seal 30. When the cleaning equipment approaches the first interface 211, the first interface 211 of the connecting pipe 20 first contacts the pipe opening of the equipment pipeline. If the height of the equipment pipeline is not completely consistent with the height of the first interface 211, the equipment pipeline will apply a force to the connecting pipe 20, causing the connecting pipe 20 to rotate, thereby finely adjusting the height of the first interface 211 until the height of the first interface 211 is aligned with the pipe opening of the equipment pipeline to achieve precise docking. It is understandable that if the first interface 211 does not protrude from the seal 30, there may be a situation where the equipment pipeline is not aligned with the first interface 211, but the edge of the seal 30 is in contact with the opening of the equipment pipeline, resulting in a false seal, which affects the actual sealing effect and increases the risk of liquid leakage. Therefore, the setting of the first interface 211 protruding from the seal 30 along the direction of the first axis M can effectively prevent the occurrence of false seals, ensure the accuracy and sealing of the connection, and further improve the stability of the pipeline connection device 1.

[0044] It should also be noted that during the docking process with the base station, the cleaning equipment is in motion. Therefore, the height of the pipe openings on the cleaning equipment will slightly change with the movement of the equipment. This causes the equipment pipe to exert a force on the first segment 21 of the connecting pipe 20. The sealing ring 33, located between the equipment pipe and the first segment 21, undergoes elastic deformation under stress to reduce wear on the connecting pipe 20. Simultaneously, the sealing ring 33 also allows for greater elastic deformation of the sealing element 30. After docking with the connecting pipe 20, it can automatically return the connecting pipe 20 to its original position, ensuring precise alignment between the connecting pipe 20 and the equipment pipe and reducing frictional losses due to positional deviations. In other words, the main body 32 and the sealing ring 33 in this embodiment possess excellent adaptability and dynamic sealing capabilities. This ensures that the equipment pipe maintains a tight fit with the first segment 21 even under varying heights, effectively preventing liquid leakage and guaranteeing the continuity and reliability of the docking process.

[0045] Furthermore, such as Figure 4 As shown, the width of the sealing ring 33 in the radial direction is r1, and r1 satisfies 1.5mm≤r1≤3mm. This is beneficial to ensure that the sealing ring 33 can have sufficient contact area with the equipment pipeline when it is deformed under force. The reasonable range of the width r1 of the sealing ring 33 in this embodiment can ensure that the sealing ring 33 can still maintain a good sealing effect when under pressure, and reduce the risk of leakage due to insufficient contact area.

[0046] Please see Figures 4-5In some embodiments of this application, the end of the connecting pipe 20 with the first interface 211 is the first end 24. The first end 24 has a first inclined portion 241 and a second inclined portion 242. The first inclined portion 241 and the second inclined portion 242 are arranged in a vertical direction, and the inclination direction of the first inclined portion 241 is opposite to the inclination direction of the second inclined portion 242. The first inclined portion 241 and the second inclined portion 242 are connected and form a protruding structure at the first end 24.

[0047] Specifically, when the cleaning equipment pipeline approaches the first end 24, the first inclined surface 241 and the second inclined surface 242 can contact the pipe opening of the equipment pipeline to provide guidance, so that the equipment pipeline drives the connecting pipe 20 to rotate through the first inclined surface 241 and the second inclined surface 242, thereby achieving precise alignment between the equipment pipeline and the first end 24 and reducing the possibility of poor sealing due to docking deviation.

[0048] In this design, the inclination direction of the first inclined portion 241 is opposite to that of the second inclined portion 242. For example, the first end of the first inclined portion 241 is connected to the first end of the second inclined portion 242. The first inclined portion 241 is inclined from bottom to top from the first end to the second end, while the second inclined portion 242 is inclined from top to bottom from the first end to the second end. This allows the inclination angles of the first and second inclined portions 241 and 242 to effectively guide the equipment pipeline towards and eventually align with the axis of the connecting pipe 20 when the equipment pipeline contacts the first end 24, ensuring the stability and sealing of the connection. Furthermore, the inclination angles of the first and second inclined portions 241 can be the same or different, depending on the specific circumstances.

[0049] Secondly, this application also provides a base station (not shown in the figure), including a base station body, a water tank assembly, and a pipeline connection device 1 as described in any of the above embodiments. The water tank assembly is disposed on the base station body; the pipeline connection device 1 is disposed on the base station body and is connected to the water tank assembly through a connecting pipe 20.

[0050] Specifically, the pipeline connection device 1 is installed in the base station body to enable the base station in this embodiment to perform pipeline connection efficiently and accurately, ensuring a stable water supply to the base station and improving cleaning efficiency. The water tank assembly includes a water tank and a flexible pipe. The flexible pipe enhances the flexibility of the connection between the second interface 221 in the pipeline connection device 1 and the water tank, allowing the flexible pipe to buffer displacement during the rotation of the connecting pipe 20, maintaining the connection stability between the second interface 221 and the water tank, thereby ensuring smooth and unobstructed water flow.

[0051] Thirdly, this application also provides a cleaning device, including a device body and a device pipeline. The device pipeline is disposed in the device body and is used to connect with the pipeline docking device 1 described in any of the above embodiments. The cleaning device can be a cleaning robot, and the device pipeline connects to the pipeline docking device 1 so that the cleaning robot can access clean water and / or discharge sewage to the outside through the pipeline docking device 1.

[0052] Fourthly, this application also provides a cleaning system, including a base station, a cleaning device (not shown in the figure), and a pipeline connection device 1 as described in any of the above embodiments. The cleaning device is used to connect with the base station for dust collection or water supply and drainage. The pipeline connection device 1 is disposed at the base station and is connected to the equipment pipeline through a first interface 211.

[0053] Specifically, the cleaning equipment precisely connects to the pipeline connection device 1 in the base station through the equipment pipeline, thereby reducing the connection error caused by the height difference between the equipment pipeline and the first interface 211, improving the connection efficiency between the cleaning equipment and the base station, reducing the probability of jamming and the frequency of secondary connection due to inaccurate connection, thereby improving the water filling and sewage discharge efficiency in the cleaning system.
