Description

Technical Field

[0002] In floor cleaning systems with wastewater tanks, wastewater in the cleaning pans or wastewater troughs is suctioned under negative pressure and then drawn into the wastewater tank through a drain pipe. A sensor is installed at the drain pipe to monitor the cleanliness of the wastewater. However, in these technologies, when the negative pressure suction stops, the residual negative pressure in the drain pipe causes some wastewater to remain inside. This retained wastewater can affect the normal operation of the floor cleaning system to some extent. Utility Model Content

[0003] The embodiments of this application aim to provide an anti-sluggish diversion device, a cleaning base station, and a cleaning system, so as to at least improve the problem in the prior art that the retention of sewage in the sewage pipes affects the normal user experience of the ground cleaning system.

[0065] This application provides an anti-traffic diversion device 10, a cleaning base station 100, and a cleaning system 1000, wherein the anti-traffic diversion device 10 is used at least in the cleaning base station 100, and the cleaning base station 100 is used at least in conjunction with the ground cleaning host 200.

[0066] Please see Figure 1 , Figure 1 This is a partial structural diagram of a clean base station 100 provided in an embodiment of this application. The diagram includes a base station module, which includes a fluid collection mechanism 20, a water collection tank 30, and an anti-stagnant diversion device 10. The two ends of the anti-stagnant diversion device 10 are respectively connected to the water collection tank 30 and the fluid collection mechanism 20.

[0067] In some embodiments, the base station module in the cleaning base station 100 can be used in conjunction with the ground cleaning host 200 to form a cleaning system 1000.

[0068] Specifically, the base station module can serve as a docking station for the ground cleaning host 200. A space for parking the ground cleaning host 200 is formed at the base station module. A ramp is also provided in this space. The ground cleaning host 200 can be used in conjunction with the base station module via the ramp to be accommodated in the space or to enter and exit relative to the accommodating space.

[0069] When the ground cleaning host 200 starts working, it can start from the base station module and execute the corresponding cleaning task; when the ground cleaning host 200 completes the cleaning task or other situations require the cleaning task to be stopped, the ground cleaning host 200 can return to the base station module to perform at least one or more of the following tasks: charging, water replenishment, cleaning, dust collection, etc.

[0070] Taking the use of a base station module to clean the ground cleaning host 200 as an example, the base station module includes a cleaning disc (which can be integrally formed with the ramp plate or detachably connected to the ramp plate) for cleaning the ground cleaning host 200. During use, the ground cleaning host 200 can be cleaned by injecting water into the cleaning disc and driving the disc to rotate. Wastewater generated during the cleaning process needs to be collected and treated.

[0071] Please see Figure 1 The base station module also includes a water collection tank 30 and a fluid collection mechanism 20. A cleaning tray is connected to the water collection tank 30, and wastewater generated at the cleaning tray flows into the water collection tank 30. To facilitate the flow of wastewater from the water collection tank 30 to the fluid collection mechanism 20, in related technologies, the fluid collection mechanism 20 includes a wastewater tank 210 and a negative pressure component 220. The negative pressure component 220 is connected to the wastewater tank 210 and provides a negative pressure environment for the wastewater tank 210. When the negative pressure component 220 is working, the liquid in the water collection tank 30 can flow to the wastewater tank 210 through corresponding pipes, and the wastewater tank 210 is used to collect wastewater.

[0072] Specifically, the negative pressure component 220 can be a vacuum pump.

[0073] To determine the cleanliness of the water after cleaning and to ascertain the number of cleaning cycles required for the floor cleaning unit 200 and its subsequent cleaning tasks, the cleanliness of the liquid flowing from the collection tank 30 needs to be tested. For example, the cleanliness of the liquid can be used to determine whether cleaning components such as the mop are properly cleaned, and to determine whether repeated cleaning / mopping is necessary. After the wastewater is suctioned out under negative pressure, some wastewater that remains in the pipe and does not flow into the wastewater tank 210 will flow back through the pipe under gravity and towards the testing element 3, allowing the testing element 3 to detect the cleanliness of the wastewater.

[0074] In related technologies, to ensure the accuracy of test results, the test piece 3 needs to be immersed in the liquid to be tested to ensure the detection accuracy of the test piece 3. However, this application has found through research that after the negative pressure component 220 finishes suction, the residual negative pressure in the pipeline will counteract gravity, causing some of the liquid to be tested to remain in the pipeline under the action of negative pressure. It is difficult for the liquid to flow back to the test piece 3 under the action of gravity, which in turn leads to a lower total amount of liquid to be tested at the test piece 3 or the presence of air bubbles, affecting its detection accuracy and ultimately resulting in insufficient accuracy of the detection results of the test piece 3. This also affects the normal use of the equipment to some extent and impacts the user experience.

[0075] In view of this, in order to solve the above problems and enable the sewage that is retained in the pipe under negative pressure, especially in the slope section 101 (the uphill section and / or downhill section in which the fluid flows during sewage collection), to flow to the detection element 3 as much as possible, this application provides an anti-stagnation diversion device 10 and a cleaning base station 100 with the device, so as to improve the detection accuracy of the detection element 3 and ultimately improve the user experience of the cleaning base station 100.

[0076] Please refer to the installation location of the anti-traffic diversion device 10 on the clean base station 100. Figure 1 and Figure 2 , Figure 2 for Figure 1 A partial cross-sectional structural diagram.

[0077] Specifically, the aforementioned anti-stagnant flow diversion device 10 can be connected to the water collection tank 30 and the fluid collection mechanism 20 of the cleaning base station 100. When the cleaning base station 100 needs to collect the liquid located in the water collection tank 30, the anti-stagnant flow diversion device 10 can guide the liquid located in the water collection tank 30 to the fluid collection mechanism 20 under negative pressure. After the cleaning base station 100 stops the negative pressure suction of the liquid located in the water collection tank 30, it can prevent the liquid from stagnating in the slope section 101 due to negative pressure and help improve the detection accuracy of the detection element 3.

[0078] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of the anti-stagnation drainage device 10 provided in a certain embodiment of this application.

[0079] Specifically, the anti-stagnant drainage device 10 includes a drainage pipe 1 and a pressure regulating component 2. The drainage pipe 1 is a tubular component used to define a fluid passage, and its interior forms a passage for fluid to pass through. One end of the drainage pipe 1 is connected to the fluid collection mechanism 20, and the drainage pipe 1 includes a sloped section 101 with a certain gradient. The pressure regulating component 2 is in fluid communication with the sloped section 101 of the drainage pipe 1 and is connected to the upper middle part of the sloped section 101 or to the fluid collection mechanism 20, so as to at least regulate the pressure of the sloped section 101 of the drainage pipe 1 and achieve pressure balance at the sloped section 101 in the drainage pipe 1. This allows at least a portion of the liquid that is stagnant in the sloped section 101 due to the residual negative pressure in the drainage pipe 1 to break the negative pressure stagnation state and resume flow under the action of gravity and flow downward along the sloped section 101.

[0080] Of course, the other end of the drainage pipe 1 is connected to the water collection tank 30, which is used to guide the liquid in the water collection tank 30 to flow through the drainage pipe 1 to the sewage tank 210 of the fluid collection mechanism 20 under negative pressure.

[0081] When the negative pressure component 220 is activated, the wastewater generated during cleaning can be drawn from the collection tank 30 into the wastewater tank 210 through the drainage pipe 1 under negative pressure suction. When the negative pressure component 220 stops, the liquid in the drainage pipe 1 that has not yet entered the wastewater tank 210 will suddenly stop moving from a high-speed state. Due to inertia, the fluid continuity is interrupted, and when some liquid retracts, a negative pressure zone is formed in the drainage pipe 1, causing some liquid to remain in the drainage pipe 1 as a liquid column. At this time, the liquid column can resist gravity under the action of negative pressure and block the drainage pipe 1. In this embodiment, by adding a pressure regulating component 2 that is fluidly connected to the slope section 101 of the drainage pipe 1, the negative pressure state remaining in at least a part of the pipe in the drainage pipe 1, especially in the slope section 101, can be adjusted after the negative pressure component 220 stops working. By disrupting the negative pressure state or reducing the negative pressure value, at least some of the liquid remaining in the slope section 101 can flow back along the slope section 101.

[0082] It should be noted that the upstream and downstream relationship of the drainage pipe 1 is determined by the fluid flow direction under negative pressure suction. In the drainage pipe 1 connecting the water collection tank 30 and the fluid collection mechanism 20, the water collection tank 30 is located upstream of the drainage pipe 1, and the fluid collection mechanism 20 is located downstream of the drainage pipe 1. Under the action of negative pressure suction, the fluid located in the water collection tank 30 can flow through the drainage pipe 1 to the fluid collection mechanism 20, and the fluid collection mechanism 20 receives the fluid discharged from the drainage pipe 1.

[0083] Please see Figure 2 and Figure 3 The anti-stagnation drainage device 10 also includes a bent section 102, which is located upstream of the slope section 101 and at the bottom of the drainage pipe 1 at a horizontal height.

[0084] It should be noted that the bottom of the horizontal height refers to the lowest area or part within that height range under a set horizontal height reference. For example, with the installation reference plane of the anti-stagnation drainage device 10 as the reference height, the bend section 102 is located in the lowest area of ​​the anti-stagnation drainage device 10. The bend section 102 located at the bottom of the drainage pipe 1 can collect fluid.

[0085] In this embodiment, the bent section 102 is connected to the end of the slope section 101 away from the fluid collection mechanism 20, so as to accumulate the liquid flowing out through the slope section 101. Under the adjustment of the air pressure regulating component 2, at least part of the liquid retained in the drainage pipe 1 due to residual negative pressure can flow along the slope section 101 to the bent section 102 and converge at the bent section 102.

[0086] Please see Figure 3 After the anti-stagnation drainage device 10 is installed in place, the bent section 102 is connected to the lowest point of the slope section 101 and bends relative to the slope section 101, thereby forming a U-shaped or similar U-shaped liquid storage cavity.

[0087] In this embodiment, the total amount of liquid flowing back to the bend section 102 through the slope section 101 can be increased by the air pressure regulating component 2, thereby helping to increase the liquid level height accumulated at the bend section.

[0088] The liquid accumulated at the bend 102 can form a water seal within the drainage pipe 1, effectively blocking it and helping to isolate the water collection tank 30 and the fluid collection mechanism 20 to some extent, thereby preventing odors and insects from entering. Most importantly, this structure can easily improve the accuracy of liquid detection in the cleaning base station 100 equipped with the aforementioned base station module.

[0089] Please see Figure 3 The clean base station 100 is also equipped with a detection element 3, which is connected to the drainage pipe 1 in the anti-stagnant drainage device 10 and is used to detect the parameters of the liquid flowing through the drainage pipe 1.

[0090] It is understood that the parameters of a liquid can include turbidity, density, light transmittance, etc., as long as the amount of dirt in the liquid can be characterized by such parameters. This embodiment does not limit the specific style of the detection element 3 or the assembly method with the drainage tube 1.

[0091] Specifically, when the fluid collection mechanism 20 includes a sewage tank 210, the liquid flowing through the drainage pipe 1 is sewage, and the aforementioned detection element 3 includes a sewage detection module 31.

[0092] In one feasible implementation, the detection element 3 is connected to the lower end of the slope section 101 in a direction perpendicular to the horizontal plane, so that the liquid flowing out of the slope section 101 under the action of gravity flows toward the detection element 3.

[0093] After the anti-stagnant drainage device 10 is installed in place, the detection element 3 is located at least below the slope section 101 of the drainage pipe 1 in a direction perpendicular to the horizontal plane, thereby ensuring that the liquid returning through the slope section 101 of the drainage pipe 1 can flow to the detection element 3 for detection.

[0094] In this embodiment, the detection element 3 is located at or near the bend section 102 (i.e., the surrounding area of ​​the bend section 102). At this time, the liquid flowing to the detection element 3 through the slope section 101 and the bend section 102 can form a sufficiently high liquid level. This allows the detection element 3 to come into contact with a sufficient amount of liquid, so that the detection element 3 can accurately detect the parameters of the liquid, thereby improving or enhancing the detection accuracy of the detection element 3.

[0095] When the liquid cleanliness detected by the detection component 3 meets the design requirements, it indicates that the cleaning component of the floor cleaning host 200 has cleaned the area properly, and cleaning can be stopped (or, it indicates that the area cleaned by the floor cleaning host 200 has been cleaned properly and does not need to be cleaned again; the next area can be cleaned or the cleaning operation can be stopped). If it does not meet the requirements, it indicates that the cleaning component of the floor cleaning host 200 has not cleaned the area properly and cleaning needs to continue (or, it indicates that the area cleaned by the floor cleaning host 200 has not been cleaned properly and cleaning operation needs to continue). Based on the above structure, the detection of liquid cleanliness can be achieved more accurately, which helps to improve the user experience.

[0096] The above structural design not only helps improve the accuracy of the detection results of the detection element 3, but also helps improve the reliability of the detection element 3 to a certain extent. For example, if the detection element 3 is in a dry or low liquid level condition for a long time, the detection part surface of the detection element 3 (such as the sensor surface) will be oxidized and contaminants will adhere due to long-term dryness, which will lead to a decrease in its detection accuracy or a decrease in detection sensitivity, and ultimately reduce the reliability of the detection element 3.

[0097] It is understood that the drainage pipe 1 provided in this application embodiment may have a continuous slope section 101 or two slope sections 101 set at intervals. This embodiment does not limit the actual number of the above slope sections 101. It is only necessary to ensure that the detection element 3 is always installed at the lowest point of the assembled drainage pipe 1. At this time, it can be ensured that as much sewage as possible flows through the drainage pipe 1 to the detection element 3.

[0098] In some embodiments, the detection element 3 may have a hollow chamber inside that communicates with the drainage tube 1. The drainage tube 1 is connected to the detection element 3, thereby guiding the liquid to flow between the drainage tube 1 and the detection element 3. Alternatively, the detection element 3 may be fitted onto the corresponding position of the drainage tube 1. This embodiment does not limit the specific connection method between the two or the detection method of the detection element 3.

[0099] In this embodiment, the pressure regulating component 2 includes a connecting pipe 21, with both ends of the connecting pipe 21 connected to the drain pipe 1 for fluid communication. Simultaneously, both ends of the connecting pipe 21 are located upstream and downstream of the detection component 3, respectively, to ensure that the connecting pipe 21 can connect with the drain pipe 1 and the detection component 3 to form a ring-shaped pressure balance circuit.

[0100] Specifically, since the detection component 3 is connected to or adjacent to the bending section 102, a connecting pipe 21 is provided to span both ends of the bending section 102. One end of the connecting pipe 21 is connected to the upper middle part of the slope section 101 or to the fluid collection mechanism 20, and the other end is connected to the upstream of the bending section 102.

[0101] Please refer to the structure of connecting pipe 21 Figure 4 , Figure 4 for Figure 3 A schematic diagram of the connecting pipe 21 is shown. In this embodiment, the connecting pipe 21 is a tubular structure with certain toughness and strength. The connecting pipe 21 can extend obliquely upward around the negative pressure member 220 and connect to the drainage pipe 1.

[0102] When the negative pressure component 220 is working, the liquid located in the water collection tank 30 can flow to the sewage tank 210 through the drainage pipe 1. After the negative pressure component 220 stops working, the gas in the connecting pipe 21 can flow into the drainage pipe 1 under the drive of the residual negative pressure in the drainage pipe 1. The gas flowing into the drainage pipe 1 can break the negative pressure balance in the drainage pipe 1, and at the same time, the liquid located in the drainage pipe 1 can overcome gravity and flow downward along the inner wall of the drainage pipe 1, or partially flow into the connecting pipe 21. The gas and liquid can form a new pressure balance between the connecting pipe 21 and the drainage pipe 1 through bidirectional flow. In this process, the negative pressure in the drainage pipe 1 is further reduced, and the liquid located in the loop formed by the drainage pipe 1 and the connecting pipe 21 can flow downward to the detection component 3 under the action of gravity.

[0103] It should be noted that after the anti-stagnation drainage device 10 is installed, any position of the connecting pipe 21 in the direction perpendicular to the horizontal plane is higher than the position of the detection element 3, so as to ensure that the liquid stagnating in the drainage pipe 1 can eventually flow to the detection element 3 for detection.

[0104] In some embodiments, the drainage tube 1 includes a first drainage portion 11 and a second drainage portion 12 connected together. The first drainage portion 11 is located on the side of the drainage tube 1 for connection with the fluid collection mechanism 20, with one end connected to the detection element 3 and the other end connected to the fluid collection mechanism 20. The second drainage portion 12 is connected to the end of the detection element 3 facing away from the first drainage portion 11. Please refer to [link to relevant documentation]. Figure 3 .

[0105] The first drainage section 11 is used at least to form the slope section 101; however, the first drainage section 11 may also include other structures. For example, the first drainage section 11 may also include at least a portion of the structure of the bend section 102. Please refer to [link / reference]. Figure 3 As mentioned above, the slope section 101 is formed in the first drainage section 11. At this time, the bend section 102 can also be formed in the first drainage section 11. The first drainage section 11 is connected to the detection element 3 through the bend section 102, and the second drainage section 12 constitutes the upstream of the bend section 102 and the detection element 3. At least part of the sewage retained in the slope section 101 in the first drainage section 11 can flow through the slope section 101 to the bend section 102 and accumulate in the bend section 102, which facilitates the detection element 3 to detect the sewage. In addition, the bend section 102 can also prevent sewage from flowing back to the collection tank 30 by accumulating sewage, so as to maintain the relative dryness of the collection tank 30.

[0106] Please see Figure 3 One end of the connecting pipe 21 is connected to the first drainage section 11, and the other end is connected to the second drainage section 12, bridging the two ends of the bent section 102. The connecting pipe 21 is connected to the end of the slope section 101 of the first drainage section 11 away from the detection element 3, or to its periphery (e.g., connected to the upper middle part of the slope section 101 or connected to the fluid collection mechanism 20). This allows for better replenishment of gas to the slope section 101 of the first drainage section 11 and at least breaks the negative pressure environment formed between the slope section 101 and the detection element 3. This enables the liquid retained in the slope section 101 of the drainage pipe 1 to resume flow and, under gravity, flow towards the bent section 102 and the detection element 3.

[0107] Specifically, the connecting pipe 21 is connected to the pipe of the first drainage section 11 near the fluid collection mechanism 20.

[0108] Figure 4 for Figure 3 A schematic diagram of the structure of the connecting pipe 21 in the diagram. Figure 5 for Figure 3 A schematic diagram showing the connection of the first connector 4, the drainage tube 1, and the connecting tube 21.

[0109] Please see Figure 3 , Figure 4 and Figure 5 The connector provided in this embodiment is connected to the upstream of the bend section 102 of the drainage tube 1 via the first connector 4.

[0110] In some embodiments, the drainage tube 1 further includes a third drainage section 13, wherein the first drainage section 11 at least forms a slope section 101 and a bend section 102 and is connected between the detection element 3 and the fluid collection mechanism 20, the second drainage section 12 is connected to the detection element 3 and is disposed upstream of the detection element 3, and the third drainage section 13 is connected to the second drainage section 12 through a first connector 4 and is located upstream of the second drainage section 12.

[0111] Specifically, the first connector 4 is a tee, including a first interface 41, a second interface 42, and a third interface 43 that are connected. In this embodiment, one end of the third drainage section 13 is connected to the water collection tank 30, and the other end is connected to the first connector 4 through the first interface 41. The second drainage section 12 is connected to the first connector 4 through the second interface 42. At this time, the first connector 4 is connected in series with the drainage pipe 1. The connecting pipe 21 is connected to the first connector 4 through the third interface 43. After the anti-stagnant drainage device 10 is assembled, in the vertical direction, the third interface 43 is higher than either the first interface 41 or the second interface 42.

[0112] By controlling the position of the third interface 43 to be higher than either the first interface 41 or the second interface 42, the amount of liquid flowing into the connecting pipe 21 through the third interface 43 during the negative pressure suction process can be reduced, ensuring that there is sufficient gas in the connecting pipe 21 to further help reduce the difficulty of backflow of liquid retained in the drainage pipe 1, increase the backflow rate of liquid, and allow more sewage to flow back to the detection element 3 and come into contact with the detection element 3.

[0113] Specifically, the aforementioned connecting pipe 21 can be connected to the third interface 43 of the first connector 4 via an interference fit or a threaded connection, thereby making the connection between the two more reliable and secure, and reducing the probability of pipe loosening. Similarly, either the second drain section 12 or the third drain section 13 can be connected to the corresponding interface of the first connector 4 via an interference fit or a threaded connection.

[0114] In some embodiments, the inner diameter of the third interface 43 is smaller than the inner diameter of either the first interface 41 or the second interface 42. This arrangement minimizes the possibility of sewage flowing into the connecting pipe 21 through the third interface 43.

[0115] The inner diameter of the third port 43 is smaller than that of the connecting pipe 21, so as to minimize the total amount of liquid entering the connecting pipe 21 through the third port 43 without changing the inner diameter of the connecting pipe 21. At this time, the connecting pipe 21 can be sealed to the third port 43 by being sleeved on the outer wall of the third port 43.

[0116] In some embodiments, the inner diameter of the connecting tube 21 is greater than or equal to 4 mm. When the inner diameter of the connecting tube 21 is too small, the amount of gas stored in the connecting tube 21 will be too small, which will affect its pressure balance function. At the same time, the liquid entering the connecting tube 21 under negative pressure will be affected by its surface tension and block the pipeline, thereby increasing the difficulty for the connecting tube 21 and the drainage tube 1 to form an airflow circulation loop. When the inner diameter of the connecting tube 21 is too large, the amount of liquid entering the connecting tube 21 will be too large, which will also affect the total amount of gas stored in the connecting tube 21 to a certain extent. This will result in a longer time for the connecting tube 21 and the drainage tube 1 to form an airflow circulation loop, thereby affecting the detection effect of the detection element 3 and the user experience.

[0117] Specifically, when the inner diameter of the connecting pipe 21 is approximately 4mm, such as 4.0mm, 4.1mm, 4.2mm, 3.9mm, or 3.8mm, the inner diameter of the third interface 43 can be set to be greater than or equal to 3mm. The inner diameter of the third interface 43 will not be too large, which can help reduce the possibility of sewage entering the connecting pipe 21 through the third interface 43, thereby reducing the impact of sewage suction operations on the gas content inside the connecting pipe 21 and thus helping to improve the gas pressure balance performance of the connecting pipe 21. Furthermore, the inner diameter of the third interface 43 will not be too small, and the probability of liquid entering the connecting pipe 21 under negative pressure clogging the pipe due to its surface tension is also low.

[0118] In other words, the connecting pipe 21 needs to store as much gas as possible, while simultaneously increasing the difficulty for sewage to enter the connecting pipe 21 through the first connector 4, so that there is enough gas in the connecting pipe 21 when the negative pressure suction operation stops. The smaller the inner diameter of the connecting pipe 21, the lower its efficiency in balancing gas pressure, and the longer it takes to establish the required gas circulation loop.

[0119] Specifically, in this embodiment, the inner diameter of the connecting tube 21 can be set to approximately 4 mm, and the inner diameter of the third interface 43 used to cooperate with the connecting tube 21 can be set to approximately 3 mm.

[0120] In some embodiments, the inner diameter of the drainage tube 1 can be set to be larger than the inner diameter of the connecting tube 21. For example, the inner diameter of the second drainage section 12 can be set to be larger than the inner diameter of the connecting tube 21. In this case, the liquid entering the first connector 4 from the third drainage tube 1 can preferentially flow to the second drainage section 12. Correspondingly, at this time, the axis of the first interface 41 of the first connector 4 and the axis of the second interface 42 are located on the same straight line or approximately on the same straight line.

[0121] Specifically, the inner diameter of the connecting tube 21 is set to approximately 4 mm. Correspondingly, the inner diameter of the second drainage section 12 can be any value among 5 mm, 5.5 mm, 6 mm, 6.3 mm, 7 mm, 7.8 mm, and 8 mm. For example, in this embodiment, the inner diameter of the drainage tube 1 or the second drainage section 12 can be set to be greater than or equal to 8 mm. Taking the second drainage section 12 as an example, its maximum inner diameter can be adaptively adjusted according to actual needs.

[0122] Please see Figure 3 The drainage pipe 1 also includes a second connector 5. The drainage pipe 1 includes a vertical section 103 connected to the fluid collection mechanism 20. The vertical section 103 is located downstream of the slope section 101 and is positioned higher than the slope section 101. One end of the connecting pipe 21 can be connected to the downstream of the slope section 101 and to the vertical section 103 via the second connector 5, so as to connect the connecting pipe 21 to the upper middle part of the slope section 101.

[0123] Specifically, the first drainage section 11 includes at least a slope section 101 and a vertical section 103 connected by a second connector 5. The vertical section 103 is located on the side of the slope section 101 facing away from the detection element 3 and is connected to the slope section 101 by the second connector 5. The other end of the vertical section 103 is connected to the fluid collection mechanism 20, and the connecting pipe 21 is connected to the first drainage section 11 by the second connector 5.

[0124] The second connector 5 is a tee, and its structure can be found in the first connector 4, so it will not be described again here.

[0125] Of course, in order to further improve the gas balance efficiency of the drainage tube 1, in some embodiments, the structure of the drainage tube 1 can be set as follows: Figure 6 As shown. Figure 6 for Figure 3 Another structural schematic diagram of the drainage tube 1 in the diagram.

[0126] Specifically, the connecting tube 21 includes a connecting part 211 and a flared part 212. One end of the connecting part 211 is connected to the flared part 212, and the other end is connected to the drainage tube 1. The inner diameter of the flared part 212 is larger than the inner diameter of the connecting part 211.

[0127] The connecting tube 21 is connected to the drainage tube 1 through the connecting part 211. Correspondingly, the connecting tube 21 can be connected to the first connector 4 through the connecting part 211. At this time, the inner diameter of the end of the connecting part 211 used to connect to the first connector 4 is not less than 4mm.

[0128] Specifically, the ratio between the maximum inner diameter of the flared part 212 and the inner diameter of the connecting part 211 can be set to be greater than or equal to 1.5. This setting can further increase the amount of gas that can be stored in the connecting pipe 21, thereby ensuring that the gas pressure balance in the pipeline can be achieved more quickly, and allowing the sewage retained in the drainage pipe 1 to flow to the detection element 3 more quickly.

[0129] In this embodiment, there are two connecting parts 211, which are respectively connected to the two ends of the flared part 212 in the length direction. One connecting part 211 is used to connect to the first connecting head 4, and the other connecting part 211 is used to connect to the second connecting head 5.

[0130] Specifically, the flared part 212 and the connecting part 211 can be an integral structure to improve the sealing performance and overall strength of the connecting pipe 21; of course, the flared part 212 and the connecting part 211 can also be a separate structure, which can reduce the processing difficulty of the connecting pipe 21.

[0131] In other embodiments, the aforementioned pressure regulating component 2 may be a structure other than the connecting pipe 21. Please refer to [link / reference needed]. Figures 7-9 .

[0132] Figure 7 This is a schematic diagram of the structure of the anti-retention drainage device 10 provided in another embodiment of this application. Figure 8 for Figure 7 A schematic diagram of the internal structure of the air pressure balancing valve 22 in the middle. Figure 9 for Figure 7 A schematic diagram of the internal structure of the air pressure balancing valve 22 in another state.

[0133] Please see Figure 7 , Figure 8 and Figure 9 The air pressure regulating component 2 includes an air pressure balancing valve 22 disposed on the drainage pipe 1. The air pressure balancing valve 22 is used to connect the slope section 101 of the drainage pipe 1 with the external environment.

[0134] Taking the installation of the air pressure balancing valve 22 on the first drainage section 11 as an example, the first drainage section 11 of the drainage pipe 1 is provided with an installation hole 1101. The air pressure balancing valve 22 is installed on the first drainage section 11 through the installation hole 1101 to connect the first drainage section 11 with the external environment, so as to realize the airflow communication between the internal space of the pipe of the first drainage section 11 and the external environment.

[0135] In this embodiment, the pressure balancing valve 22 is configured to be in a closed state under a predetermined negative pressure state, that is, when the fluid pressure in the first drain portion 11 at the mounting hole 1101 is lower than a predetermined value, the pressure balancing valve 22 can be closed.

[0136] Specifically, the aforementioned mounting hole 1101 is opened at one end of the first drainage section 11 near the sewage tank 210, and correspondingly, the air pressure balancing valve 22 is also installed at one end of the first drainage section 11 near the sewage tank 210.

[0137] In some embodiments, the pressure balancing valve 22 includes a valve body 221, a sealing member 222, and an elastic reset member 223, wherein the valve body 221 is mounted on the first drain portion 11 through the mounting hole 1101. The valve body 221 has a connecting cavity 2211 and a connecting port 2212. The connecting cavity 2211 is connected to the drainage pipe 1, and the connecting port 2212 is used to connect the connecting cavity 2211 to the external environment. The sealing member 222 is limited to the connecting cavity 2211 and has a first position and a second position within the connecting cavity 2211. When the sealing member 222 is in the first position within the connecting cavity 2211, the connecting cavity 2211 can be connected to the external environment through the connecting port 2212. When the sealing member 222 is in the second position within the connecting cavity 2211, the sealing member 222 can disconnect the connecting cavity 2211 from the external environment by blocking the connecting port 2212. The elastic reset member 223 is limited to the space between the sealing member 222 and the connecting cavity 2211 and abuts against the sealing member 222. The elastic reset member 223 controls the movement of the sealing member 222 from the second position to the first position through deformation.

[0138] It should be noted that, along the gas flow direction, the first position is located on the side opposite to the second position, opposite to the drainage tube 1. When the negative pressure component 220 is not activated, the sealing component 222 can be positioned in the first position under the push of the elastic reset component 223. At this time, the connecting cavity 2211 can maintain communication with the external environment through the connecting port 2212, meaning the air pressure in the connecting cavity 2211 is consistent with the ambient air pressure. Simultaneously, the connecting cavity 2211 is connected to the drainage tube 1, and the air pressure within the first drainage section 11 is also consistent with the ambient air pressure. Please refer to [link / reference]. Figure 8 When the negative pressure component 220 is activated, if the fluid pressure in the first drainage section 11 at the mounting hole 1101 is lower than a predetermined value, the sealing component 222 located in the connecting cavity 2211 can move towards the side closer to the first drainage section 11 under the negative pressure suction, thereby moving from the first position to the second position. During this process, the connecting port 2212 is closed by the sealing component 222. The sealing component 222 can and can only be connected to the first drainage section 11 and maintain a negative pressure state. At this time, the elastic reset component 223 can be deformed under the squeezing action of the sealing component 222. Please refer to [link / reference]. Figure 9After the negative pressure component 220 is closed again, when the fluid pressure in the first drainage section 11 at the mounting hole 1101 is higher than the predetermined value, the elastic force of the elastic reset component 223 is greater than the fluid pressure difference on both sides of the sealing component 222. The elastic reset component 223, which is in a deformed state, recovers its deformation and pushes the sealing component 222 back from the second position to the first position, so that the connecting cavity 2211 is connected to the external environment again. This allows the ambient gas to enter the first drainage section 11 through the connecting port 2212 and the connecting cavity 2211, thereby achieving the regulation of the air pressure in the first drainage section 11. This allows at least some of the liquid that was trapped in the first drainage section 11 due to negative pressure to break the negative pressure trapping state and resume flow under the action of gravity and flow to the detection component 3.

[0139] It is important to note that, in Figure 9 In the indicated state, in response to the negative pressure within the slope section 101 of the first drainage section 11, the sealing member 222 moves from the first position to the second position, at which time the elastic reset member 223 deforms and stores energy. The stored energy can be released when the negative pressure member 220 is closed, and push the sealing member 222 from the second position to the first position (in this case, the force provided by the negative pressure environment formed within the slope section 101 of the first drainage section 11 is significantly less than the elastic pushing force provided by the elastic reset member 223).

[0140] In some embodiments, please refer to Figure 8 and Figure 9 The connecting cavity 2211 is provided with a limiting surface 2213 on the side near the first drainage part 11, and the elastic reset member 223 abuts against the limiting surface 2213.

[0141] Specifically, the elastic reset member 223 includes at least one of a spring and a spring sheet. In this embodiment, the elastic reset member 223 includes a spring, one end of which abuts against the limiting surface 2213, and the other end of which abuts against the sealing member 222.

[0142] It is understood that the anti-stagnant drainage device 10 provided in this application embodiment can be used to improve the problem of low detection accuracy of the detection element 3 caused by the liquid to be tested stagnating in the drainage pipe 1. By ensuring that there is enough sewage to wet the detection element 3 installed on the drainage pipe 1, the detection accuracy of the detection element 3 is improved, thereby ensuring the reliability of the detection results of the detection element 3 in the device, which helps to further improve the user experience of the cleaning base station 100 and the cleaning system 1000.

[0143] The clean base station 100 equipped with the aforementioned anti-traffic diversion device 10 has the effects described above, which will not be repeated here.

[0144] Based on the same concept, this application also provides a cleaning system 1000, please refer to... Figure 10The cleaning system 1000 includes the cleaning base station 100 described above, and also includes a ground cleaning host 200 that works in conjunction with the cleaning base station 100.

[0145] Figure 10 This is a partial structural schematic diagram of a cleaning system 1000 provided in an embodiment of this application. In this embodiment, the cleaning system 1000 includes a cleaning base station 100 and a floor cleaning host 200 (the shape in the figure is only for illustration). The cleaning base station 100 has a space formed on it for accommodating the floor cleaning host 200 (e.g., a sweeping robot, a mopping robot, etc.).

[0146] When the base station module cleans the ground cleaning host 200, some wastewater is generated. This wastewater can be discharged through its internal drainage pipe under negative pressure suction. It is understood that the internal drainage pipe of the base station module in the cleaning base station 100 provided in this embodiment is connected to a wastewater tank 210 for containing wastewater, so that the wastewater is discharged into the wastewater tank 210. The wastewater in the wastewater tank 210 can be discharged into the sewer through a sewage pipe connecting the wastewater tank 210 and the sewer.

[0147] In some embodiments, the anti-stagnation diversion device 10 is located in the base station module of the clean base station 100 and is used to communicate with the sewage tank 210 and the water collection tank 30 to guide the sewage generated when the base station module is working to flow from the water collection tank 30 into the sewage tank 210.

[0148] In some embodiments, the cleaning base station 100 further includes a clothing processing tube 40 for processing clothing, the clothing processing tube 40 being located in the upper half of the cleaning base station 100 and above the space for accommodating the ground cleaning host 200.

[0149] The cleaning base station 100 integrates the clothes handling tube 40 and the floor cleaning host 200 for cleaning the floor into the same device, which helps to reduce the space occupied by related cleaning appliances in the home, and can also effectively improve the overall stability, reliability and security of the cleaning base station 100.

[0150] Please see Figure 10 In this embodiment, the cleaning base station 100 has a box-like structure, forming an internal space for simultaneously accommodating the clothing processing tube 40 and the base station module. The clothing processing tube 40 and the base station module are arranged at intervals within the aforementioned internal space, with the base station module located below the clothing processing tube 40. Of course, in other similar embodiments, the base station module located in the internal space may also be arranged horizontally at intervals or adjacent to the clothing processing tube 40.

[0151] In this embodiment, the clothing handling drum 40 can be a washing drum for washing clothes, a drying drum for drying clothes, or a drum that combines washing and drying functions. A space is formed at the base station module for placing the floor cleaning host 200. A ramp is also provided in this space, allowing the floor cleaning host 200 to be used in conjunction with the base station module to be accommodated within the space or to move in and out relative to the space. This embodiment does not limit the clothing handling function of the clothing handling drum 40; that is, the clothing handling function of the clothing handling drum 40 can include washing and / or drying functions. In other words, the cleaning base station 100 provided in this application embodiment can be a cleaning base station 100 with a washing function, a cleaning base station 100 with a drying function, or a cleaning base station 100 with both washing and drying functions, etc.

[0152] In some embodiments, the above-mentioned anti-stagnation diversion device 10 can also be connected to the clothing processing cylinder 40 of the cleaning base station 100, and used to guide the sewage generated when the clothing processing cylinder 40 is working into the corresponding sewage storage container (e.g., condensate tank, etc.) under negative pressure.

[0153] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.

[0154] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
