Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0034] The cleaning system according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0035] like Figures 1 to 7 As shown, according to the cleaning system 100 of the embodiment of the utility model, it includes: a cleaning base station 20 and a cleaning device 10, the cleaning base station 20 includes a liquid supply tank 22, a liquid supply pipe 23 and a functional component 24, one end of the liquid supply pipe 23 is connected to the liquid supply tank 22, and the functional component 24 is arranged on the liquid supply pipe 23, the cleaning device 10 and the cleaning base station 20 are detachably matched and include a liquid storage tank 11, wherein, when the cleaning device 10 and the cleaning base station 20 are matched, the other end of the liquid supply pipe 23 is detachably connected to the liquid storage tank 11, and the cleaning liquid in the liquid supply tank 22 is suitable for being transported to the liquid storage tank 11 through the liquid supply pipe 23, and the functional component 24 is configured to control the liquid supply tank 22 to stop supplying liquid to the liquid supply pipe 23 and control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22 when the liquid level in the liquid storage tank 11 reaches a preset liquid level.

[0036] That is to say, the cleaning base station 20 stores cleaning liquid through the liquid supply tank 22, and the cleaning base station 10 stores cleaning liquid through the liquid storage tank 11. The cleaning base station 10 cleans the ground with the cleaning liquid in the liquid storage tank 11. When the cleaning liquid in the liquid storage tank 11 is exhausted, the cleaning equipment 10 can be moved to the cleaning base station 20 and cooperate with the cleaning base station 20. After the cleaning equipment 10 cooperates with the cleaning base station 20, the liquid supply tank 22 can be connected to the liquid storage tank 11 through the liquid supply pipe 23, that is, the liquid supply pipe 23 can form a connecting flow channel between the liquid supply tank 22 and the liquid storage tank 11, so that the cleaning liquid in the liquid supply tank 22 can be transported to the liquid storage tank 11 to realize the liquid replenishment operation of the liquid storage tank 11. When the liquid level in the liquid storage tank 11 reaches the preset liquid level, that is, there is no need to continue to transport cleaning liquid into the liquid storage tank 11, the functional component 24 controls the liquid supply tank 22 to stop supplying liquid to the liquid supply pipe 23 to stop transporting cleaning liquid to the liquid storage tank 11, which can prevent the cleaning liquid in the liquid storage tank 11 from exceeding the upper limit of the capacity and overflowing. In addition, the functional component 24 controls the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22, that is, the cleaning liquid in the liquid supply pipe 23 is cleaned and passed through the liquid storage tank 11 and / or the liquid supply tank 22 to avoid residual cleaning liquid in the liquid supply pipe 23, thereby preventing the cleaning device 10 from being separated from the cleaning base station 20 and the residual cleaning liquid in the liquid supply pipe 23 from flowing out through the end of the liquid supply pipe 23 away from the liquid supply tank 22, causing waste or polluting the surrounding environment. In addition, when the end of the liquid supply pipe 23 away from the liquid supply tank 22 is in a lower position, the residual liquid in the liquid supply pipe 23 can be discharged to avoid the residual liquid in the liquid supply pipe 23 from forming a siphon effect, thereby avoiding the waste caused by the liquid supply pipe 23 continuously discharging the cleaning liquid in the liquid supply tank 22 under the siphon effect.

[0037] Therefore, when the liquid level in the liquid storage tank 11 reaches a preset liquid level, the functional component 24 can control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22, so as to avoid the cleaning liquid remaining in the liquid supply pipe 23 from flowing out through the end of the liquid supply pipe 23 away from the liquid supply tank 22 after the cleaning equipment 10 is separated from the cleaning base station 20, causing waste or polluting the surrounding environment. At the same time, it can avoid the residual liquid in the liquid supply pipe 23 from forming a siphon effect, thereby avoiding the waste caused by the liquid supply pipe 23 continuously discharging the cleaning liquid in the liquid supply tank 22 under the siphon effect.

[0038] It should be noted that when the liquid level in the liquid storage tank 11 reaches a preset liquid level, the functional component 24 can control the cleaning liquid in the liquid supply pipe 23 to flow into the liquid storage tank 11; or the functional component 24 can control the cleaning liquid in the liquid supply pipe 23 to flow into the liquid supply tank 22; or the functional component 24 can control a part of the cleaning liquid in the liquid supply pipe 23 to flow into the liquid storage tank 11 and the other part to flow into the liquid supply tank 22, and no specific restrictions are made here.

[0039] According to the cleaning system of the embodiment of the utility model, when the liquid level in the liquid storage tank 11 reaches a preset liquid level, the functional component 24 can clean the cleaning liquid in the liquid supply pipe 23 to avoid residual cleaning liquid in the liquid supply pipe 23. This can prevent the cleaning liquid remaining in the liquid supply pipe 23 from flowing out through the end of the liquid supply pipe 23 away from the liquid supply tank 22 after the cleaning equipment 10 is separated from the cleaning base station 20, causing waste or polluting the surrounding environment. At the same time, it can prevent the residual liquid in the liquid supply pipe 23 from forming a siphon effect, thereby preventing the liquid supply pipe 23 from continuously discharging the cleaning liquid in the liquid supply tank 22 under the siphon effect. Waste caused by this

[0040] According to some embodiments of the utility model, the other end of the liquid supply pipe 23 has a docking joint 2333 suitable for corresponding to the cleaning device 10, and the position height of the docking joint 2333 is lower than the bottom surface of the liquid supply box 22. In other words, the liquid supply box 22 is located above the docking joint 2333, so that sufficient matching space can be reserved below the liquid supply box 22 for the cleaning device 10 to enter the cleaning base station 20, so as to facilitate the cleaning of the cleaning device 10 in the cleaning base station 20. In addition, the docking joint 2333 is located below the bottom surface of the liquid supply box 22, which is convenient for the docking joint 2333 to dock with the cleaning device 10. For example, the docking joint 2333 can be at approximately the same height as the cleaning device 10, which is conducive to reducing the difficulty of matching and connecting the cleaning device 10 with the docking joint 2333.

[0041] According to some embodiments of the present invention, the cleaning device 10 includes a delivery pump 13, which is used to drive the cleaning liquid in the liquid supply tank 22 to be delivered to the liquid storage tank 11 through the liquid supply pipe 23. That is, when the cleaning device 10 cooperates with the cleaning base station 20 and the end of the liquid supply pipe 23 away from the liquid supply tank 22 is connected to the liquid storage tank 11, the cleaning liquid in the liquid supply tank 22 can be delivered to the liquid storage tank 11 for storage through the delivery pump 13. As a result, the automation level of replenishing liquid in the liquid supply tank 22 can be improved, so that the operation of the user using the cleaning system 100 can be reduced, which is conducive to improving the user experience.

[0042] According to some embodiments of the utility model, the cleaning system 100 has a liquid replenishment mode and a residual liquid discharge mode. In the liquid replenishment mode, the cleaning device 10 cooperates with the cleaning base station 20, and the cleaning liquid in the liquid supply tank 22 is transported to the liquid storage tank 11 through the liquid supply pipe 23 and the functional component 24 does not work. At this time, the liquid supply tank 22 is connected to the liquid storage tank 11 through the liquid supply pipe 23, so that the cleaning liquid in the liquid supply tank 22 can enter the liquid storage tank 11 through the liquid supply pipe 23 to achieve liquid replenishment, and the functional component 24 does not work to avoid the functional component 24 affecting the flow of the cleaning liquid into the liquid storage tank 11, thereby ensuring the normal progress of the liquid replenishment process. In the residual liquid discharge mode, the cleaning device 10 cooperates with the cleaning base station 20, and the functional component 24 works. That is to say, at this time, the liquid supply pipe 23 is still connected to the liquid storage tank 11, but the cleaning liquid in the liquid supply tank 22 stops flowing into the liquid storage tank 11 through the liquid supply pipe 23, and the functional component 24 works to control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22, thereby preventing the residual cleaning liquid in the liquid supply pipe 23 from flowing out or causing waste due to the siphon effect.

[0043] In some embodiments, the cleaning system 100 has a liquid replenishment mode, a residual liquid discharge mode, and a cleaning mode. In the liquid replenishment mode, the cleaning device 10 cooperates with the cleaning base station 20, the delivery pump 13 works, and the functional component 24 does not work. At this time, the liquid supply tank 22 is connected to the liquid storage tank 11 through the liquid supply pipe 23. Under the drive of the delivery pump 13, the cleaning liquid in the liquid supply tank 22 enters the liquid storage tank 11 through the liquid supply pipe 23, thereby realizing the operation of replenishing the liquid storage tank 11. In the residual liquid discharge mode, the cleaning device 10 cooperates with the cleaning base station 20, and the functional component 24 works. At this time, the liquid supply pipe 23 is still connected to the liquid storage tank 11, but the cleaning liquid in the liquid supply tank 22 stops flowing into the liquid storage tank 11 through the liquid supply pipe 23. The functional component 24 works to control the cleaning liquid in the liquid supply pipe 23 to flow into at least one of the liquid storage tank 11 and the liquid supply tank 22, thereby preventing the residual cleaning liquid in the liquid supply pipe 23 from flowing out or generating waste caused by the siphon effect. In the cleaning mode, the cleaning device 10 is separated from the cleaning base station 20. After being separated from the cleaning base station 20, the cleaning device 10 can continue to clean the surface to be cleaned. During this process, the delivery pump 13 delivers the cleaning liquid in the liquid storage tank 11 to the mopping member 12 to improve the cleaning effect and cleaning efficiency.

[0044] According to some embodiments of the utility model, the cleaning device 10 includes a liquid level sensor, which is arranged in the liquid storage tank 11. When the cleaning device 10 cooperates with the cleaning base station 20, the functional component 24 is electrically connected to the liquid level sensor. Among them, the liquid level of the cleaning liquid in the liquid storage tank 11 can be accurately obtained through the liquid level sensor. Therefore, in the process of conveying the cleaning liquid to the liquid storage tank 11 through the liquid supply tank 22 via the liquid supply pipe 23, when the liquid level in the liquid storage tank 11 reaches the preset liquid level, since the functional component 24 is electrically connected to the liquid level sensor, the liquid level sensor can transmit the signal that the liquid level in the liquid storage tank 11 has reached the preset liquid level to the functional component 24. After receiving the signal, the functional component 24 switches to the working state and cleans the cleaning liquid in the liquid supply pipe 23. Therefore, through the cooperation of the liquid level sensor and the functional component 24, the control signal can be transmitted to the functional component 24 in time after the cleaning liquid in the liquid storage tank 11 reaches the preset liquid level, which is conducive to improving the automation level of the cleaning system 100.

[0045] According to some embodiments of the present invention, the functional component 24 includes: a first pump body 241, the first pump body 241 is connected to the liquid supply pipe 23, and the first pump body 241 is configured to, when the liquid level in the liquid storage tank 11 reaches a preset liquid level, the first pump body 241 delivers gas to the liquid supply pipe 23, so that the liquid supply tank 22 stops supplying liquid to the liquid supply pipe 23 and the cleaning liquid in the liquid supply pipe 23 flows into at least one of the liquid storage tank 11 and the liquid supply tank 22. That is, when the liquid level in the liquid storage tank 11 reaches the preset liquid level, the gas delivered to the liquid supply pipe 23 by the first pump body 241 can cut off the flow of the cleaning liquid in the liquid supply pipe 23 to the liquid storage tank 11, and at the same time can push the cleaning liquid in the liquid supply pipe 23 to flow toward the liquid storage tank 11 and / or the liquid supply tank 22 to empty the cleaning liquid in the liquid supply pipe 23. Therefore, the cleaning liquid in the liquid supply pipe 23 is emptied by gas-driven liquid flow, which is low-cost and can better avoid introducing other types of liquids into the liquid supply pipe 23, thereby improving the reliability of the first pump body 241 in cleaning the cleaning liquid in the liquid supply pipe 23.

[0046] According to some embodiments of the utility model, the liquid supply pipe 23 includes a first pipe section 231, a second pipe section 232 and a third pipe section 233 which are connected in sequence, the first pipe section 231 extends in the up-down direction, at least a portion of the third pipe section 233 extends in the up-down direction, the second pipe section 232 has an angle with the first pipe section 231 and the third pipe section 233, the lower end of the first pipe section 231 is connected to the liquid supply tank 22, the lower end of the third pipe section 233 has a docking joint 2333 suitable for corresponding to the cleaning equipment 10, the second pipe section 232 is connected to the upper end of the first pipe section 231 and the upper end of the third pipe section 233, and the first pump body 241 is connected to the second pipe section 232.

[0047] That is, the first pipe section 231 and the third pipe section 233 are connected through the second pipe section 232, and the end of the first pipe section 231 away from the second pipe section 232 is connected to the liquid supply tank 22, and the end of the third pipe section 233 away from the second pipe section 232 has a docking joint 2333, and the third pipe section 233 is docked with the cleaning device 10 through the docking joint 2333, so as to realize the connection between the third pipe section 233 and the liquid storage tank 11. Therefore, in the residual liquid discharge mode, since the first pump body 241 is connected to the second pipe section 232, the first pump body 241 can transport gas into the second pipe section 232, and the gas entering the second pipe section 232 is divided into two parts, one part of the gas flows in the direction close to the first pipe section 231, thereby pushing the cleaning liquid located at the upstream side of the connection position between the first pump body 241 and the second pipe section 232 in the liquid supply pipe 23 to flow into the upper end of the first pipe section 231, and the first pipe section 231 extends in the up-down direction, so that the liquid in the first pipe section 231 can be pushed by the gas and the gravity. The gas flows downward into the liquid supply tank 22 to avoid the cleaning liquid remaining in the first pipe section 231; the other part of the gas flows toward the direction close to the third pipe section 233, thereby pushing the cleaning liquid in the liquid supply pipe 23 located at the downstream side of the connection position between the first pump body 241 and the second pipe section 232 to flow into the upper end of the third pipe section 233. At least the part of the third pipe section 233 connected to the second pipe section 232 extends in the up-down direction, so that the cleaning liquid in the third pipe section 233 can flow downward into the liquid storage tank 11 under the push of the gas and the action of gravity, so as to avoid the cleaning liquid remaining in the third pipe section 233. In this way, the cleaning effect of the residual cleaning liquid in the liquid supply pipe 23 can be improved.

[0048] According to some embodiments of the utility model, the second pipe segment 232 extends in a straight line or is formed into an arc that bends upward. Thus, it is possible to better avoid the second pipe segment 232 bending downward, resulting in the cleaning liquid remaining in the second pipe segment 232. In addition, when the second pipe segment 232 is formed into an arc that bends upward, that is, the second pipe segment 232 is low at both ends and high in the middle in the extension direction, the cleaning liquid remaining in the second pipe segment 232 can flow toward the two ends of the second pipe segment 232 under the action of gravity, and further flow into the liquid supply tank 22 and the liquid storage tank 11 through the first pipe segment 231 and the third pipe segment 233, respectively, to ensure that the cleaning liquid in the second pipe segment 232 can be drained. In a specific example, the second pipe segment 232 extends in a straight line in the horizontal direction.

[0049] According to some embodiments of the present utility model, the third pipe section 233 includes a vertical section 2331 and a docking section 2332, the vertical section 2331 extends in the up-down direction and the upper end of the vertical section 2331 is connected to the second pipe section 232, the docking section 2332 and the vertical section 2331 have an angle, and the docking section 2332 has a docking head 2333. That is, one end of the docking section 2332 is connected to one end of the vertical section 2331 away from the second pipe section 232, and the other end of the docking section 2332 has a docking head 2333 to facilitate docking of the cleaning device 10. Among them, the cleaning device 10 is usually moved horizontally into the cleaning base station 20 to cooperate with the cleaning base station 20. As a result, the docking section 2332 arranged at an angle with the vertical section 2331 is convenient for the cleaning device 10 to move horizontally into the cleaning base station 20 and cooperate with the docking head 2333 on the docking section 2332, that is, it is conducive to reducing the difficulty of docking the docking head 2333 with the cleaning device 10. In a specific example, the docking section 2332 and the vertical section 2331 are vertically arranged, which helps to further reduce the difficulty of docking the docking head 2333 with the cleaning device 10.

[0050] According to some embodiments of the present invention, the functional component 24 is located below the second pipe segment 232 and between the liquid supply box 22 and the third pipe segment 233. Thus, the functional component 24 can make full use of the space below the second pipe segment 232 and between the liquid supply box 22 and the third pipe segment 233, thereby reducing the installation space occupied by the functional component 24 and the liquid supply pipe 23 in the extension direction of the second pipe segment 232, with a compact structure and a reasonable layout.

[0051] According to some embodiments of the utility model, the functional component 24 includes a first connecting pipeline 243 and a second connecting pipeline 244, the first connecting pipeline 243 connects the first pump body 24 and the liquid supply pipe 23, the second connecting pipeline 244 is connected to the first pump body 24, the first connecting pipeline 243 is connected to the upper side of the first pump body 24, and the second connecting pipeline 244 is connected to the lower side of the first pump body 24. That is, the first pump body 241 is connected to the liquid supply pipe 23 through the first connecting pipeline 243, and in the up and down direction, the first pump body 241 is connected between the first connecting pipeline 243 and the second connecting pipeline 244. Therefore, in the residual liquid discharge mode, the first pump body 241 can inhale gas through the second connecting pipeline 244, and transport the gas to the liquid supply pipe 23 through the first connecting pipeline 243 to discharge the cleaning liquid in the liquid supply pipe 23. In addition, in the cleaning mode, the first pump body 241 is connected to the liquid supply tank 22 through the first connecting pipeline 243 and the liquid supply pipe 23, so that the liquid in the liquid supply tank 22 can flow into the cleaning tank 25 of the cleaning base station 20 through the liquid supply pipe 23 and the first connecting pipeline 243, the first pump body 241 and the second connecting pipeline 244 under the drive of the first pump body 241, so that the mopping member 12 of the cleaning device 10 can be cleaned by the cleaning liquid in the cleaning tank 25. In a specific example, the lower end of the second connecting pipeline 244 is located directly above the cleaning tank 25 to ensure the reliability of conveying the cleaning liquid into the cleaning tank 25.

[0052] According to some embodiments of the utility model, the cleaning device 10 includes a delivery pump 13, which is used to drive the cleaning liquid in the liquid supply box 22 to be delivered to the liquid storage tank 11 through the liquid supply pipe 23. In the residual liquid discharge mode, the delivery pump 13 does not work. That is, when the cleaning liquid in the liquid supply pipe 23 is cleaned by the first pump body 241, the delivery pump 13 stops driving the cleaning liquid in the liquid supply box 22 to be delivered to the liquid storage tank 11 through the liquid supply pipe 23. As a result, it can be better to avoid that the gas delivered to the liquid supply pipe 23 by the first pump body 241 due to the operation of the delivery pump 13 enters the liquid storage tank 11 through the liquid supply pipe 23, thereby avoiding that the liquid storage tank 11 is in a negative pressure state, resulting in the cleaning liquid in the liquid supply box 22 still being able to enter the liquid storage tank 11 through the liquid supply pipe 23, that is, it can be better to avoid that the delivery pump 13 affects the first pump body 241 to discharge the residual liquid in the liquid supply pipe 23, which is conducive to improving the discharge effect of the functional component 24 on the cleaning liquid in the liquid supply pipe 23.

[0053] According to some embodiments of the present utility model, the cleaning device 10 includes a delivery pump 13, which is used to drive the cleaning liquid in the liquid supply tank 22 to be delivered to the liquid storage tank 11 through the liquid supply pipe 23. In the residual liquid discharge mode, the delivery pump 13 works and the operating power of the delivery pump 13 is less than the operating power of the first pump body 241. The operating power of the delivery pump 13 is less than the operating power of the first pump body 241, which means that the amount of cleaning liquid delivered by the delivery pump 13 per unit time is less than the amount of cleaning liquid that can be delivered by the first pump body 241 per unit time. Therefore, the delivery pump 13 can only pump part of the gas delivered to the liquid supply pipe 23 by the first pump body 241 into the liquid storage tank 11, thereby driving the cleaning liquid in the liquid supply pipe 23 between the gas input position of the first pump body 241 and the liquid storage tank 11 to flow into the liquid storage tank 11, and the remaining part of the gas delivered to the liquid supply pipe 23 by the first pump body 241 can drive the cleaning liquid in the liquid supply pipe 23 between the air input position of the first pump body 241 and the liquid supply tank 22 to flow into the liquid supply tank 22, so as to clean the residual liquid in the liquid supply pipe 23.

[0054] According to some embodiments of the present invention, the cleaning base station 20 includes a cleaning component and a cleaning tank 25, and the cleaning component includes a second pump body 242, and the second pump body 242 is connected to the liquid supply tank 22, so as to transport the cleaning liquid in the liquid supply tank 22 to the cleaning tank 25. Thus, the cleaning device 10 can be cleaned by the cleaning liquid transported to the cleaning tank 25 by the second pump body 242. For example, after the cleaning device 10 cooperates with the cleaning base station 20, the mopping and wiping member 12 of the cleaning device 10 is located in the cleaning tank 25, so the cleaning liquid in the cleaning tank 25 can better remove the mud and dirt contaminated by the mopping and wiping member 12 in the process of cleaning the surface to be cleaned, so as to restore the cleanliness of the mopping and wiping member 12, which is conducive to improving the cleaning effect of the cleaning device 10 on the surface to be cleaned.

[0055] According to some embodiments of the utility model, the first pump body 241 and the second pump body 242 are the same pump body, and the cleaning system 100 has a cleaning mode, wherein in the cleaning mode, the first pump body 241 rotates forward, and the first pump body 241 rotates forward to transport the cleaning liquid in the liquid supply box 22 to the cleaning tank 25, so as to clean the mopping member 12 in the cleaning tank 25 with the cleaning liquid in the cleaning tank 25; in the residual liquid discharge mode, the first pump body 241 rotates reversely, and the first pump body 241 rotates reversely to transport gas into the liquid supply pipe 23 to clean the cleaning liquid in the liquid supply pipe 23. Therefore, by integrating the functions of transporting the cleaning liquid into the cleaning tank 25 and transporting the gas into the liquid supply pipe 23 into the first pump body 241, the integration of the first pump body 241 can be well improved and the second pump body 242 can be saved, so that the number of parts of the cleaning base station 20 can be reduced, which is conducive to simplifying the structure of the cleaning base station 20 and reducing the production and manufacturing cost of the cleaning base station 20.

[0056] In a specific example, the first pump body 241 is a peristaltic pump, so that the first pump body 241 can realize the transportation of a variety of different media, such as liquid and gas, and at the same time can better ensure the accuracy and stability of the first pump body 241, and the operation noise is small.

[0057] According to some embodiments of the present invention, the cleaning device 10 includes a liquid storage tank 11, a mopping member 12 and a delivery pump 13. The mopping member 12 is used to clean the surface to be cleaned. The delivery pump 13 is connected to the liquid storage tank 11 and is used to deliver external cleaning liquid to the liquid storage tank 11 and to deliver the cleaning liquid in the liquid storage tank 11 to the mopping member 12. That is, the liquid storage tank 11 is used to store the cleaning liquid. During the process of the cleaning device 10 cleaning the surface to be cleaned, if the mopping member 12 is in contact with the surface to be cleaned and is movable relative to the surface to be cleaned so as to remove dirt on the surface to be cleaned by rubbing the surface to be cleaned with the mopping member 12, the delivery pump 13 can deliver the cleaning liquid in the liquid storage tank 11 to the mopping member 12 to wet the mopping member 12. The mopping member 12 soaked with the cleaning liquid can more effectively remove dirt on the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency of the cleaning device 10 on the surface to be cleaned. When the cleaning liquid in the liquid storage tank 11 is exhausted, the cleaning device 10 can be moved to the liquid replenishment location, where the liquid replenishment location refers to the storage location of the external cleaning liquid. The liquid storage tank 11 is connected to the storage location of the external cleaning liquid, and the external cleaning liquid is transported to the liquid storage tank 11 through the delivery pump 13 to ensure that the cleaning liquid in the liquid storage tank 11 can be continuously transported to the mopping member 12 to clean the surface to be cleaned. In this way, the integration of the delivery pump 13 can be improved to reduce the number of delivery pumps 13, that is, reduce the number of parts of the cleaning device 10, which is conducive to simplifying the structure of the cleaning device 10 and reducing the production cost of the cleaning device 10. At the same time, it is convenient to reduce the overall size of the cleaning device 10 to improve the passing capacity of the cleaning device 10, which is conducive to broadening the applicable scenarios of the cleaning device 10.

[0058] The cleaning liquid may be water, a cleaning agent such as a floor cleaning agent for cleaning the surface to be cleaned, or a mixed liquid of a cleaning agent and water, etc., and the type of the cleaning liquid is not specifically limited. In addition, the external cleaning liquid may be stored in a cleaning base station 20 that is detachably matched with the cleaning device 10, and the cleaning device 10 may be replenished with the cleaning liquid by returning to the cleaning base station 20. The external cleaning liquid may also come directly from a tap, etc., and there is no specific limitation here.

[0059] In a specific example, the delivery pump 13 is a diaphragm pump, so that the delivery pump 13 can realize the delivery of a variety of different media, such as liquid and gas, and has good sealing performance to prevent leakage of the delivered medium.

[0060] According to some embodiments of the utility model, the cleaning device 10 has a liquid replenishing mode and a cleaning mode. In the liquid replenishing mode, the delivery pump 13 delivers the external cleaning liquid to the liquid storage tank 11 and stops delivering the cleaning liquid to the mopping and wiping member 12. In the cleaning mode, the delivery pump 13 delivers the cleaning liquid in the liquid storage tank 11 to the mopping and wiping member 12 and stops delivering the external cleaning liquid to the liquid storage tank 11. Thus, the cleaning device 10 can replenish the cleaning liquid in the liquid storage tank 11 in the liquid replenishing mode, and at the same time can avoid the waste caused by the delivery of the cleaning liquid to the mopping and wiping member 12. After the liquid storage tank 11 is replenished, the cleaning device 10 can continue to clean the surface to be cleaned. In the cleaning mode, the cleaning liquid is delivered to the mopping and wiping member 12 by the delivery pump 13, so that the mopping and wiping member 12 soaked with the cleaning liquid can more effectively remove the dirt on the surface to be cleaned, thereby better ensuring the cleaning effect and cleaning efficiency of the cleaning device 10 on the surface to be cleaned in the cleaning mode.

[0061] According to some embodiments of the utility model, the cleaning device 10 includes: a first pipeline assembly and a second pipeline assembly, the first pipeline assembly is connected to both the liquid storage tank 11 and the delivery pump 13, so as to deliver the external cleaning liquid to the liquid storage tank 11, and the second pipeline assembly is connected to both the liquid storage tank 11 and the delivery pump 13, so as to deliver the cleaning liquid in the liquid storage tank 11 to the mopping member 12. That is to say, the first pipeline assembly can form a communicating liquid passage between the external cleaning liquid storage area and the liquid storage tank 11, and under the drive of the delivery pump 13, the external cleaning liquid can enter the liquid storage tank 11 through the first pipeline assembly connecting the cleaning liquid storage area and the portion of the liquid storage tank 11, so as to replenish the cleaning liquid in the liquid storage tank 11; the second pipeline assembly can form a communicating liquid passage between the liquid storage tank 11 and the installation area of ​​the mopping member 12, and under the drive of the delivery pump 13, the cleaning liquid in the liquid storage tank 11 can be delivered to the mopping member 12 through the second pipeline assembly connecting the portion of the liquid storage tank 11 and the installation area of ​​the mopping member 12 to wet the mopping member 12.

[0062] Therefore, the cleaning liquid can be added to the liquid storage tank 11 through the cooperation of the delivery pump 13 and the cleaning liquid can be delivered to the mopping member 12 through the cooperation of the delivery pump 13 and the second pipeline assembly. That is, the needs of replenishing the cleaning liquid and wetting the mopping member 12 with the cleaning liquid can be met through the cooperation of the delivery pump 13 and the first pipeline assembly and the second pipeline assembly, which can better improve the integration of the delivery pump 13 and reduce the number of delivery pumps 13.

[0063] According to some embodiments of the present utility model, the first pipeline assembly includes a liquid inlet pipeline 141, an air extraction pipeline 142 and an exhaust pipeline 143, one end of the liquid inlet pipeline 141 is connected to the liquid storage tank 11 and the other end is formed with a docking port 1411, one end of the air extraction pipeline 142 is connected to the liquid storage tank 11 and the other end is connected to the inlet of the delivery pump 13, and the exhaust pipeline 143 is connected to the outlet of the delivery pump 13. Among them, the docking port 1411 is used to dock with the storage location of the external cleaning liquid, such as the docking port 1411 can cooperate with the docking head 2333 of the liquid supply tank 22 storing the cleaning liquid of the cleaning base station 20 or the docking port 1411 can be directly docked with the faucet of the tap, etc., and no specific restrictions are made here. That is to say, when replenishing liquid into the liquid storage tank 11, the docking port 1411 is docked with the storage position of the external cleaning liquid, that is, one end of the liquid inlet pipeline 141 is connected to the storage position of the external cleaning liquid, and the other end is connected to the liquid storage tank 11, so that a connected liquid channel can be formed between the storage position of the external cleaning liquid and the liquid storage tank 11 through the liquid inlet pipeline 141; the two ends of the air extraction pipeline 142 are respectively connected to the liquid storage tank 11 and the inlet of the delivery pump 13, so that a connected air flow channel can be formed between the liquid storage tank 11 and the delivery pump 13 through the air extraction pipeline 142, and the delivery pump 13 is connected between the air extraction pipeline 142 and the exhaust pipeline 143. Under the drive of the delivery pump 13, the gas in the liquid storage tank 11 can be discharged through the air extraction pipeline 142, the delivery pump 13 and the exhaust pipeline 143 in sequence.

[0064] Therefore, when it is necessary to replenish cleaning liquid into the liquid storage tank 11, after the docking port 1411 is docked with the storage position of the external cleaning liquid, the gas in the liquid storage tank 11 can be continuously discharged through the delivery pump 13, the exhaust pipe 142 and the exhaust pipe 143. As the gas in the liquid storage tank 11 is discharged, the air pressure value in the liquid storage tank 11 also decreases, that is, the liquid storage tank 11 is operated to draw a negative pressure through the delivery pump 13 to form a pressure difference between the storage position of the external cleaning liquid and the liquid storage tank 11, so that the external cleaning liquid can flow into the liquid storage tank 11 through the liquid inlet pipe 141 under the action of the pressure difference, so as to realize the operation of replenishing the liquid in the liquid storage tank 11.

[0065] The second pipeline assembly includes a liquid extraction pipeline 151 and a liquid discharge pipeline 152. One end of the liquid extraction pipeline 151 is connected to the liquid storage tank 11 and the other end is connected to the inlet of the delivery pump 13. The liquid discharge pipeline 152 is connected to the outlet of the delivery pump 13. In other words, the two ends of the liquid extraction pipeline 151 are respectively connected to the inlet of the liquid storage tank 11 and the delivery pump 13, so that a liquid channel connected between the liquid storage tank 11 and the inlet of the delivery pump 13 can be formed through the liquid extraction pipeline 151. The delivery pump 13 is connected between the liquid extraction pipeline 151 and the liquid discharge pipeline 152. Therefore, under the drive of the delivery pump 13, the liquid in the liquid storage tank 11 can be sequentially delivered to the mopping member 12 through the liquid extraction pipeline 151, the delivery pump 13 and the liquid discharge pipeline 152, so as to realize the operation of delivering the cleaning liquid to the mopping member 12.

[0066] Among them, the connection position between the air extraction pipeline 142 and the liquid storage tank 11 is the first connection position, and the connection position between the liquid extraction pipeline 151 and the liquid storage tank 11 is the second connection position, and the first connection position is higher than the second connection position. That is to say, the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142 is higher than the position where the cleaning liquid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid extraction pipeline 151. Therefore, the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142, that is, the first connection position, is set at a relatively high position, which can avoid the cleaning liquid in the liquid storage tank 11 being extracted during the process of pumping negative pressure into the liquid storage tank 11. In addition, the position where the cleaning liquid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid extraction pipeline 151, that is, the second connection position, is set at a relatively low position, which can better ensure that the cleaning liquid in the liquid storage tank 11 can be drained and drained, so as to avoid the cleaning liquid remaining in the liquid storage tank 11 to cause waste or dirt.

[0067] In a specific example, one end of the drainage pipe 152 is connected to the outlet of the delivery pump 13, and the other end of the drainage pipe 152 is located above the mopping member 12 and is open downward, so that the cleaning liquid can be sprayed downward from the top of the mopping member 12 to the mopping member 12 through the drainage pipe 152.

[0068] According to some embodiments of the utility model, the first connection position is located at the upper end of the liquid storage tank 11, and the second connection position is located at the lower end of the liquid storage tank 11. Among them, the delivery pump 13 draws negative pressure to the liquid storage tank 11 through the air extraction pipeline 142 so that the external cleaning liquid can enter the liquid storage tank 11 under the action of the pressure difference. When the liquid level in the liquid storage tank 11 is higher than the first connection position, the cleaning liquid in the liquid storage tank 11 will be extracted through the air extraction pipeline 142, that is, the first connection position is the highest position where the delivery pump 13 and the first pipeline assembly can cooperate to deliver the cleaning liquid into the liquid storage tank 11. Therefore, by setting the first connection position at the upper end of the liquid storage tank 11, the amount of cleaning liquid delivered to the liquid storage tank 11 by the delivery pump 13 and the first pipeline assembly can be increased, that is, the delivery pump 13 and the first pipeline assembly can cooperate to make the external cleaning liquid roughly fill the liquid storage tank 11, thereby avoiding the waste of storage space in the liquid storage tank 11, and at the same time, it is beneficial to improve the endurance of the cleaning device 10.

[0069] In addition, the second connection position is set at the lower end of the liquid storage tank 11, that is, the position where the cleaning liquid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid pumping pipeline 151 is located at the lower end of the liquid storage tank 11, so that the cleaning liquid in the liquid storage tank 11 can be drained and drained under the cooperation of the delivery pump 13 and the liquid pumping pipeline 151, so as to avoid the cleaning liquid remaining in the liquid storage tank 11 to cause waste or dirt.

[0070] In a specific example, the first connection position is located at the top of the liquid storage tank 11. Therefore, when the liquid level in the liquid storage tank 11 has not reached the top of the liquid storage tank 11, the external cleaning liquid can continue to flow into the liquid storage tank 11 under the action of the negative pressure of the delivery pump 13 and the exhaust pipe 142 on the liquid storage tank 11 until the liquid level in the liquid storage tank 11 reaches the top of the liquid storage tank 11, thereby avoiding the waste of storage space in the liquid storage tank 11 and achieving high utilization rate.

[0071] According to some embodiments of the utility model, the connection position between the liquid inlet pipeline 141 and the liquid storage tank 11 is a third connection position, and the third connection position is lower than the first connection position. Among them, the connection position between the liquid inlet pipeline 141 and the liquid storage tank 11 is the position where the external cleaning liquid enters the liquid storage tank 11, that is, the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 is lower than the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the exhaust pipeline 142. In this way, it is possible to avoid the cleaning liquid in the liquid storage tank 11 being extracted during the process of pumping negative pressure into the liquid storage tank 11, and at the same time, it is possible to avoid wasting the storage space in the liquid storage tank 11.

[0072] In some embodiments, the first connection position and the third connection position are both higher than the highest liquid level in the liquid storage tank 11. That is, when the cleaning liquid in the liquid storage tank 11 reaches the highest liquid level, the position where the liquid inlet pipe 141 delivers the cleaning liquid to the liquid storage tank 11 and the position where the delivery pump 13 sucks the air in the liquid storage tank 11 are still located above the liquid surface. In this way, the delivery pump 13 can be prevented from pumping out the cleaning liquid in the liquid storage tank 11, and the resistance of the liquid inlet pipe 141 to deliver the cleaning liquid to the liquid storage tank 11 can be reduced.

[0073] In some embodiments, the first connection position and the third connection position are both located at the top of the liquid storage tank 11. Thus, it can be ensured that the external cleaning liquid fills the liquid storage tank 11 under the action of the negative pressure drawn by the delivery pump 13 on the liquid storage tank 11. At the same time, since the connection position between the liquid inlet pipeline 141 and the liquid storage tank 11 is also located at the top of the liquid storage tank 11, the liquid inlet pipeline 141 does not need to overcome the resistance of the cleaning liquid in the liquid storage tank 11 when entering the liquid storage tank 11, that is, the resistance of the external cleaning liquid entering the liquid storage tank 11 through the liquid inlet pipeline 141 can be reduced, which is conducive to reducing the energy consumption of the delivery pump 13 in delivering the external cleaning liquid to the liquid storage tank 11.

[0074] According to some embodiments of the present invention, the connection position between the liquid inlet pipeline 141 and the liquid storage tank 11 is a third connection position, the third connection position is higher than the second connection position, and the third connection position is located at the upper part of the liquid storage tank 11. In other words, the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 is higher than the position where the cleaning liquid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid extraction pipeline 151. Therefore, by setting the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipe 141 at a relatively high position, it can be avoided that the cleaning liquid in the liquid storage tank 11 hinders the external cleaning liquid from entering the liquid storage tank 11 through the liquid inlet pipe 141, thereby reducing the resistance of the external cleaning liquid entering the liquid storage tank 11 through the liquid inlet pipe 141, which is beneficial to reducing the energy consumption of the delivery pump 13 in delivering the external cleaning liquid to the liquid storage tank 11; by setting the position where the cleaning liquid in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the liquid pumping pipe 151, that is, the second connection position, at a relatively low position, it can be better ensured that the cleaning liquid in the liquid storage tank 11 can be drained, so as to avoid the cleaning liquid remaining in the liquid storage tank 11 to cause waste or dirt.

[0075] According to some embodiments of the utility model, the connection position between the liquid inlet pipeline 141 and the liquid storage tank 11 is the third connection position, and the third connection position and the first connection position are located on the same side of the liquid storage tank 11. That is, the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142 and the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 are located on the same side of the liquid storage tank 11. As a result, the interval between the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142 and the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 can be shortened, that is, the position where the negative pressure is pumped to the liquid storage tank 11 is close to the position where the external cleaning liquid enters the liquid storage tank 11, so that the negative pressure pumping effect of the delivery pump 13 at the third connection position can be improved, and then the pressure difference between the storage position of the external cleaning liquid and the third position can be increased, which is conducive to improving the efficiency of the external cleaning liquid entering the liquid storage tank 11.

[0076] According to some embodiments of the utility model, the spacing range L between the first connection position and the third connection position satisfies: 0<L≤100mm. That is, the spacing between the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142 and the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 is controlled within the range of 0 to 100mm. For example, the spacing between the position where the gas in the liquid storage tank 11 is discharged from the liquid storage tank 11 through the air extraction pipeline 142 and the position where the external cleaning liquid enters the liquid storage tank 11 through the liquid inlet pipeline 141 can be: 5mm, 8mm, 10mm, 20mm, 30mm, 40mm, 60mm, 80mm, 100mm, etc., and no specific restrictions are made here. In this way, it is possible to avoid the distance between the first connection position and the third connection position being too small, resulting in the external cleaning liquid entering the liquid storage tank 11 through the liquid inlet pipe 141 and then being directly sucked away by the air exhaust pipe 142. At the same time, it is possible to avoid the distance between the first connection position and the third connection position being too large, which affects the negative pressure extraction effect of the air exhaust pipe 142 on the third connection position. In this way, the negative pressure value at the place where the external cleaning liquid enters the liquid storage tank 11 can be ensured while avoiding the cleaning liquid entering the liquid storage tank 11 through the liquid inlet pipe 141 from being sucked into the air exhaust pipe 142. The layout is reasonable.

[0077] According to some embodiments of the present invention, the air extraction pipeline 142 is provided with a first control valve 144 , and the first control valve 144 is used to control the conduction and cutoff of the air extraction pipeline 142 . That is to say, the air extraction pipeline 142 can be controlled to be connected through the first control valve 144, so as to form a connected gas channel between the liquid storage tank 11 and the delivery pump 13 through the air extraction pipeline 142, so that under the action of the delivery pump 13, the gas in the liquid storage tank 11 can be discharged through the air extraction pipeline 142, the delivery pump 13 and the exhaust pipeline 143 in sequence to draw a negative pressure into the liquid storage tank 11, so that the external cleaning liquid can enter the liquid storage tank 11 under the action of the pressure difference; the air extraction pipeline 142 can be controlled to be cut off through the first control valve 144, that is, the connection between the delivery pump 13 and the liquid storage tank 11 through the air extraction pipeline 142 is cut off, so as to avoid the air extraction pipeline 142 being turned on, causing the delivery pump 13 to extract the gas in the liquid storage tank 11, resulting in the inability to extract the cleaning liquid in the liquid storage tank 11 through the liquid extraction pipeline 151, so as to ensure the stability of the cleaning liquid delivery to the mopping member 12.

[0078] Specifically, when the external cleaning liquid is delivered to the liquid storage tank 11 through the cooperation of the delivery pump 13 and the first pipeline assembly, the first control valve 144 controls the air extraction pipeline 142 to be connected; when the cleaning liquid in the liquid storage tank 11 is delivered to the mopping member 12 through the cooperation of the delivery pump 13 and the second pipeline assembly, the first control valve 144 controls the air extraction pipeline 142 to be cut off.

[0079] According to some embodiments of the utility model, a cleaning base station 20 that is detachably matched with a cleaning device 10 is provided with a trigger 21. When the cleaning device 10 is matched with the cleaning base station 20, the docking port 1411 is connected with the cleaning base station 20, and the trigger 21 triggers the first control valve 144 to open the exhaust pipe 142. That is to say, when the liquid storage tank 11 needs to be replenished, the cleaning device 10 returns to the cleaning base station 20 and after the docking port 1411 is connected with the cleaning base station 20, the first control valve 144 can be automatically controlled to open the exhaust pipe 142 through the cooperation between the trigger 21 and the first control valve 144, that is, after the docking port 1411 is connected with the cleaning base station 20, there is no need to separately control the first control valve 144 to open the exhaust pipe 142. At this time, a gas channel connected between the liquid storage tank 11 and the delivery pump 13 can be formed through the exhaust pipe 142, and the delivery pump 13 can draw negative pressure to the liquid storage tank 11 through the exhaust pipe 142 so that the outside The cleaning liquid can enter the liquid storage tank 11 under the action of the pressure difference; when the liquid storage tank 11 is replenished, if the liquid level in the liquid storage tank 11 reaches the preset liquid level, the cleaning device 10 can be separated from the cleaning base station 20 to continue the cleaning operation, and the effect of the trigger 21 on the first control valve 144 disappears, and the first control valve 144 cuts off the air extraction pipeline 142, that is, after the cleaning device 10 leaves the cleaning base station 20, there is no need to separately control the first control valve 144 to cut off the air extraction pipeline 142, so as to ensure that the cleaning liquid in the liquid storage tank 11 can be delivered to the mopping member 12 through the liquid extraction pipeline 151, the delivery pump 13 and the liquid discharge pipeline 152. Therefore, the step of separately controlling the first control valve 144 to conduct or cut off the air extraction pipeline 142 can be omitted, which is conducive to improving the automation level of the first control valve 144 and reducing the control difficulty of the first control valve 144.

[0080] According to some embodiments of the present invention, the first control valve 144 and the docking port 1411 are located on the same side of the cleaning device 10. Thus, the difficulty of matching the docking port 1411 and the first control valve 144 with the cleaning base station 20 can be reduced.

[0081] According to some embodiments of the present invention, the first control valve 144 includes a valve core 1441, and the valve core 1441 is movable between a conducting position and a cut-off position. That is, when the valve core 1441 is in the conducting position, the first control valve 144 conducts the exhaust pipeline 142, and when the valve core 1441 is in the cut-off position, the first control valve 144 cuts off the exhaust pipeline 142. The valve core 1441 is movable between the conducting position and the cut-off position, so that the first control valve 144 can conduct and cut off the exhaust pipeline 142.

[0082] When the cleaning device 10 is matched with the cleaning base station 20, there is a force between the trigger 21 and the valve core 1441 to drive the valve core 1441 to move to the conduction position. When the cleaning device 10 is disengaged from the cleaning base station 20, the valve core 1441 is located at the cut-off position. In other words, when the trigger 21 is not matched with the valve core 1441, the valve core 1441 is often in the cut-off position, that is, when the trigger 21 does not trigger the first control valve 144, the first control valve 144 is often in the position of cutting off the exhaust pipeline 142. When the trigger 21 cooperates with the valve core 1441 to generate a force on the valve core 1441, the valve core 1441 moves from the cut-off position to the conduction position to conduct the exhaust pipeline 142. Therefore, through the cooperation between the trigger member 21 and the valve core 1441, the function of automatically opening the exhaust pipeline 142 when the cleaning device 10 and the cleaning base station 20 are cooperated can be better realized, and the function of automatically cutting off the exhaust pipeline 142 when the cleaning device 10 and the cleaning base station 20 are separated can be eliminated. The step of separately controlling the first control valve 144 to open or cut off the exhaust pipeline 142 can be eliminated, which is beneficial to improving the automation level of the first control valve 144 and reducing the difficulty of controlling the first control valve 144.

[0083] According to some embodiments of the utility model, the first control valve 144 includes an elastic reset member 1442, one end of the elastic reset member 1442 is connected to the exhaust pipeline 142 and the other end is connected to the valve core 1441, and the elastic reset member 1442 is used to drive the valve core 1441 to move to the cut-off position. In other words, the elastic reset member 1442 has a tendency to drive the valve core 1441 to move toward the cut-off position. Therefore, when the cleaning device 10 is separated from the cleaning base station 20, the force between the trigger member 21 and the valve core 1441 disappears, and the valve core 1441 is maintained at the cut-off position under the action of the elastic reset member 1442 to cut off the exhaust pipeline 142; when the cleaning device 10 is matched with the cleaning base station 20, the force between the trigger member 21 and the valve core 1441 drives the valve core 1441 to overcome the elastic force of the elastic reset member 1442 and move from the cut-off position to the conducting position to open the exhaust pipeline 142. Therefore, the valve core 1441 in the conduction position can be reset to the cut-off position through the elastic reset member 1442 after the cleaning equipment 10 is separated from the cleaning base station 20, thereby effectively eliminating the operation of resetting the valve core 1441 separately, which is beneficial to improving the automation level of the first control valve 144 and reducing the control difficulty of the first control valve 144.

[0084] According to some embodiments of the utility model, when the cleaning device 10 cooperates with the cleaning base station 20, there is a magnetic force between the trigger 21 and the valve core 1441, which is used to drive the valve core 1441 to move to the conduction position. That is to say, when the cleaning device 10 cooperates with the cleaning base station 20, the magnetic force between the trigger 21 and the valve core 1441 drives the valve core 1441 to squeeze the elastic reset member 1442 to move toward the direction close to the trigger 21, thereby realizing the movement of the valve core 1441 from the cut-off position to the conduction position to open the exhaust pipeline 142; after the cleaning device 10 is separated from the cleaning base station 20, the magnetic force between the trigger 21 and the valve core 1441 disappears, that is, the force acting on the valve core 1441 to squeeze the elastic reset member 1442 to move toward the conduction position disappears, and the valve core 1441 moves from the conduction position to the cut-off position under the thrust of the elastic reset member 1442 to restore the deformation and cut off the exhaust pipeline 142. Therefore, through the magnetic cooperation between the trigger member 21 and the valve core 1441, the difficulty of the trigger member 21 controlling the first control valve 144 to conduct or cut off the exhaust pipeline 142 can be reduced. At the same time, the structure is simple, the reliability is high and the investment cost is low.

[0085] According to some embodiments of the present invention, the exhaust pipeline 143 and the drain pipeline 152 are the same pipeline. That is, only one exhaust pipeline 143 or one drain pipeline 152 is required, and the gas delivered by the delivery pump 13 can be discharged and the cleaning liquid delivered by the delivery pump 13 can be delivered to the wiping member 12 through the exhaust pipeline 143 or the drain pipeline 152. In this way, the pipeline cost can be well saved, and the installation space occupied by the exhaust pipeline 143 or the drain pipeline 152 can be saved.

[0086] According to some embodiments of the utility model, a second control valve is provided on the exhaust pipeline 143, and the second control valve is used to control the conduction and cutoff of the exhaust pipeline 143. That is, the second control valve can control the conduction of the exhaust pipeline 143, so that when the delivery pump 13 draws negative pressure to the liquid storage tank 11 through the air extraction pipeline 142, the gas extracted from the liquid storage chamber can be discharged through the exhaust pipeline 143; the second control valve can control the cutoff of the exhaust pipeline 143, so that when the delivery pump 13 extracts the cleaning liquid in the liquid storage tank 11 through the liquid extraction pipeline 151, the cleaning liquid extracted by the delivery pump 13 can only be delivered to the mopping and wiping member 12 through the liquid discharge pipeline 152, so as to prevent the cleaning liquid from flowing out through the exhaust pipeline 143 and affecting the wetting effect on the mopping and wiping member 12.

[0087] According to some embodiments of the utility model, the first pipeline assembly includes a first pipeline and a second pipeline, one end of the first pipeline is connected to the inlet of the delivery pump 13 and the other end is formed as a docking port 1411, wherein the docking port 1411 is used to dock with the storage position of the external cleaning liquid, one end of the second pipeline is connected to the outlet of the delivery pump 13 and the other end is connected to the liquid storage tank 11, a third control valve is provided on the first pipeline, and the third control valve is used to control the conduction and cutoff of the first pipeline, and a fourth control valve is provided on the second pipeline, and the fourth control valve is used to control the conduction and cutoff of the second pipeline, and the second pipeline assembly includes a third pipeline and a fourth pipeline, one end of the third pipeline is connected to the inlet of the delivery pump 13 and the other end is connected to the liquid storage tank 11, and the fourth pipeline is connected to the outlet of the delivery pump 13, and a fifth control valve is provided on the third pipeline, and the fifth control valve is used to control the conduction and cutoff of the third pipeline, and a sixth control valve is provided on the fourth pipeline, and the sixth control valve is used to control the conduction and cutoff of the fourth pipeline.

[0088] That is, the delivery pump 13 can be connected to the external cleaning liquid storage location through the first pipeline, the delivery pump 13 can be connected to the liquid storage tank 11 through the second pipeline and the third pipeline, and the delivery pump 13 can also deliver the cleaning liquid to the mopping and wiping member 12 through the fourth pipeline. Among them, the first pipeline, the second pipeline, the third pipeline and the fourth pipeline can be independently controlled to be connected or cut off, so that by controlling the connection or cutoff of the first pipeline, the second pipeline, the third pipeline and the fourth pipeline respectively, a single delivery pump 13 can be used to deliver the external cleaning liquid to the liquid storage tank 11 and the cleaning liquid in the liquid storage tank 11 to the mopping and wiping member 12, which is conducive to simplifying the structure of the cleaning device 10.

[0089] Specifically, when it is necessary to replenish the liquid in the liquid storage tank 11, after the docking port 1411 is connected to the storage position of the external cleaning liquid, the third control valve is controlled to connect the first pipeline, the fourth control valve is controlled to connect the second pipeline, the third pipeline is cut off by the fifth control valve, and the fourth pipeline is cut off by the sixth control valve, so that under the drive of the delivery pump 13, the external cleaning liquid can only be delivered to the liquid storage tank 11 through the first pipeline, the delivery pump 13, and the second pipeline in sequence; when it is necessary to deliver the cleaning liquid in the liquid storage tank 11 to the mopping and wiping member 12, the third control valve is controlled to cut off the first pipeline, the fourth control valve is controlled to cut off the second pipeline, the third pipeline is connected by the fifth control valve, and the fourth pipeline is connected by the sixth control valve, so that under the drive of the delivery pump 13, the cleaning liquid in the liquid storage tank 11 can only be delivered to the mopping and wiping member 12 through the third pipeline, the delivery pump 13, and the fourth pipeline in sequence.

The liquid supply box 22 is located above the cleaning tank 25. The liquid supply pipe 23 includes a first pipe section 231, a second pipe section 232 and a third pipe section 233. The first pipe section 231 extends in the up-down direction, the second pipe section 232 extends in the horizontal direction, and the third pipe section 233 includes a vertical section 2331 extending in the up-down direction and a docking section 2332 extending in the horizontal direction.

The functional component 24 includes a first pump body 241, a second pump body 242, a first connecting pipeline 243 and a second connecting pipeline 244. The first pump body 241 and the second pump body 242 are the same pump body and the first pump body 241 can rotate forward and reverse to achieve driving of the fluid in two directions. The upper end of the first connecting pipeline 243 is connected to the middle position of the second pipe section 232, the first pump body 241 is connected to the lower end of the first connecting pipeline 243 and the upper end of the second connecting pipeline 244, and the lower end of the second connecting pipeline 244 is located directly above the cleaning tank 25.

[0093] Specifically, the cleaning system 100 has a liquid replenishing mode, a residual liquid discharging mode, a washing mode, and a cleaning mode.

[0094] In the replenishment mode, the cleaning device 10 returns to the cleaning base station 20 and cooperates with the cleaning base station 20. At this time, the docking head 2333 is connected to the docking port 1411, the liquid supply pipe 23 is connected to the liquid inlet pipe 141, and the trigger member 21 attracts the valve core 1441 to squeeze the elastic reset member 1442 and move it to the conduction position. At this time, the air extraction pipe 142 is in a conduction state, and the first pump body 241 is controlled to be closed and the delivery pump 13 is controlled to be turned on. The delivery pump 13 discharges the gas in the liquid storage tank 11 through the air extraction pipe 142 and the exhaust pipe 143, and a negative pressure is formed in the liquid storage tank 11. The cleaning liquid in the liquid supply tank 22 enters the liquid storage tank 11 along the liquid supply pipe 23 and the liquid inlet pipe 141 under the action of the pressure difference on both sides until the cleaning liquid in the liquid storage tank 11 reaches the preset liquid level.

[0095] In the residual liquid discharge mode, when the cleaning liquid in the liquid storage tank 11 reaches a preset liquid level, the delivery pump 13 is controlled to close and the first pump body 241 is controlled to reverse, thereby delivering the gas to the second pipe section 232 through the second connecting pipe 244 and the first connecting pipe 243. The gas entering the second pipe section 232 is divided into two streams flowing toward the liquid supply tank 22 and the liquid storage tank 11, thereby pushing the liquid in the liquid supply pipe 23 to flow into the liquid supply tank 22 and the liquid storage tank 11 until the residual liquid in the liquid supply pipe 23 is drained.

[0096] In the cleaning mode, the delivery pump 13 is controlled to be closed and the first pump body 241 is controlled to rotate forward.
