Technical Field

[0003] The present invention relates to the field of cleaning equipment, and in particular to a base station, a base station control method and a cleaning robot. Background Art

[0004] Cleaning robots often require water during operation, so the cleaning base station should be installed some distance from a water source. The cleaning base station and water source can be directly connected via external water pipes. Because cleaning base stations can be installed in a variety of locations, external water pipes may be located in places like the living room and kitchen.

[0005] During extended use, external pipes and connectors connecting the water source to the cleaning base station could become damaged at any time and in any location. Since faucets are typically kept open to supply water to the cleaning base station, any damage to these pipes or connectors could cause water to leak directly into the living room, kitchen, and other areas, potentially damaging the home or causing leaks, resulting in a poor user experience.

[0068] In the present invention, the description of directions such as "up", "down", "left" and "right" is as follows: Figures 1 to 4 The directions shown are for reference only and are used to explain the Figures 1 to 4 The relative positional relationship between the components in the shown posture. If the specific posture changes, the directional indication will also change accordingly.

[0069] The present invention provides a base station.

[0070] Please refer to Figures 1 to 4 , the base station includes:

[0071] An internal water channel structure, the internal water channel structure being connected to a water source via an external water pipe 20;

[0072] An electronic control device is used to control the external switch device 200 connected to the external water pipe 20, and the electronic control device is used to obtain a trigger signal and send a control signal to the external switch device 200 so that the external switch device 200 changes the connection state according to the control signal.

[0073] The base station is connected to an external water pipe 20, and an external water source provides water to the base station through the external water pipe 20, such as for cleaning mops, sprinkling water, etc. For convenience, the water source switch faucet is generally in an open state. When the base station is short of water or needs water, the water source is directly pumped into the water base station.

[0074] Since the external water pipe 20 may leak, in this embodiment, the external switch device 200 is provided at the position where the external water pipe 20 is connected to the switch faucet. The external switch device 200 is used to open or close the switch faucet.

[0075] Optionally, the switch valve 201 is used to open or close the external water pipe 20 connected to the water source.

[0076] The electric control device of the base station is connected to the external switch device 200 and is used to trigger the external switch device 200 to open or close, so as to change the connection state of the external water pipe 20 by opening or closing the external switch device 200 .

[0077] Optionally, the electronic control device sends a control signal to the external switch device 200 based on the acquired trigger signal, so as to trigger the external switch device 200 to change the connection state. The trigger signal includes a time signal or a state signal.

[0078] Optionally, when the trigger signal is a time signal, the electronic control device sends a signal to the external switch device 200 based on the acquired time signal to trigger the external switch device 200 to change the connection state.

[0079] Optionally, the time signal may be pre-set, such as triggering the time signal at a preset time point, or triggering the time signal after the base station has been working for a preset time period, or triggering the time signal after the base station has been idle for a preset time period.

[0080] For example, if a day is used as a unit of time, the external switch device 200 is triggered to open the water source during a certain time period within the unit of time to centrally supply water to the base station. Alternatively, the external switch device 200 is triggered to close the water source during a certain time period within the unit of time, so that after the water supply ends, the water is turned off during the time period to prevent water leakage.

[0081] Alternatively, if the base station is set to operate once a day, or once every three days, the water supply time is set after the base station has operated for a preset time, triggering the external switch device 200 to open the water source. Alternatively, after the base station has operated for a preset time, the external switch device 200 is triggered to close the water source (the external switch device 200 is a normally open water valve. When the base station is operating, the water source supplies water. After the base station has finished operating, the water source is closed after a preset time to prevent water leakage).

[0082] Alternatively, based on the N times the base station operates daily, N corresponding time periods are set, with a time signal generated for each time period. Each time the electronic control device receives a time signal, it triggers the external switch device 200, causing it to change its connection state. For example, within N time periods, the external water pipe is periodically opened for water replenishment. Optionally, the duration of each water replenishment can be set, with a time signal generated again within a preset time interval. When the electronic control device receives a time signal again within the preset time interval, it triggers the external switch device 200 to close the external water pipe. The preset time interval can be 3-5 minutes. This time interval is determined based on the water flow rate and the water tank capacity.

[0083] Optionally, the time signal may be set based on user settings, such as setting a timed on or timed off, etc. It may also be set based on the actual historical water usage times of the base station.

[0084] Optionally, the trigger signal is a status signal, which may be a status signal of a water tank, a status signal of an internal water pipe, a status signal of an external water pipe, or a working status signal of a functional component.

[0085] Optionally, the water tank may be an external water storage tank of the base station or a water storage tank inside the base station. The following description will take the water tank inside the base station as an example. Optionally, the functional components include a power pump or a mop drying component.

[0086] For example, if the base station further includes a functional component, or the internal waterway structure includes a water tank and an internal water pipe, the water tank is connected to the water source. Optionally, the internal water pipe includes a first water pipe and / or a second water pipe, the first water pipe connects the water tank and the water source, and the second water pipe connects the water tank and the water-using parts corresponding to each functional component. In this way, the electronic control device in this embodiment can trigger the external switch device 200 on the external water pipe 20 to change the connection state through the status signal of the water tank, the status signal of the internal water pipe, the status signal of the external water pipe, or the working status signal of the functional component. Based on the automatic triggering of the external switch device 200 by the electronic control device to switch the connection state, the external water pipe 20 is opened when there is a demand for water, and the external water pipe 20 is closed in time when there is no demand for water or there is a risk of leakage, thereby effectively preventing the external water pipe 20 from leaking.

[0087] Optionally, in one embodiment, the electronic control device includes a control sensor, which is used to detect a status signal and send a signal to the external switch device 200 .

[0088] The control sensor has the function of detecting a status signal and sending a control signal. Based on this, the external switch device 200 can be controlled by the control sensor.

[0089] Optionally, in this embodiment, the status signal may be any one of a status signal of the water tank, a status signal of the internal water pipe, and a working status signal of the functional component.

[0090] That is, in this embodiment, the control sensor is used to detect a status signal from the water tank of the base station, a status signal from the internal water pipe of the base station, or an operating status signal from the functional component. Based on any of the detected status signals, the control sensor then sends a signal to the external switch device 200 to trigger the external switch device 200 to change the conduction state of the external water pipe.

[0091] As in the first embodiment, the status signal is a working status signal of the functional component, and the control sensor is used to send a control signal to the external switch device 200 when detecting that the functional component starts working or stops working.

[0092] In this embodiment, the functional component includes a power pump or a mop drying component of the base station.

[0093] Optionally, when the control sensor detects that the functional component is working, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open the external water pipe 20; or, when the control sensor detects that the functional component stops working, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close.

[0094] In this embodiment, the functional components of the base station are controlled in conjunction with the external switch device 200 via the control sensor. Based on the start or stop of the functional components, the control sensor sends a control signal to the external switch device 200, triggering the external switch device 200 to open the external water pipe 20, thereby connecting the external water pipe 20 to the water tank and supplying water to the base station, or to close the external water pipe 20, thereby stopping the external water pipe 20 from supplying water to the base station and preventing water leakage in the pipe section between the external water pipe 20 and the base station.

[0095] For example, when the functional component is started, the control sensor can detect the working signal of the functional component, and the control sensor triggers the external switch device 200 to open the external water pipe 20 (in the scenario where the switch valve 201 of the external switch device 200 is a normally closed water valve 21). Alternatively, when the functional component stops working, the control sensor can detect the stop working signal of the functional component, and the control sensor triggers the external switch device 200 to close (the switch valve 201 of the external switch device 200 can be a normally closed water valve 21 or a normally open water valve 21). The control sensor 40 is used to realize the linkage control between the external switch device 200 and the functional component, so that the external switch device 200 is opened when the functional component needs water to supply water to the cleaning base station. When the functional component finishes working or ends, the switch device 200 is closed to prevent the external water pipe 20 from leaking.

[0096] Optionally, in other embodiments, the control sensor may also detect that the functional component stops working and send an opening signal to the external switch device 200 to trigger the external switch device 200 to open the external water pipe 20 after the functional component stops working.

[0097] As in the second embodiment, the status signal includes the status signal of the water tank, and the control sensor is a water level detection element or a water pressure sensor 50 located in the water tank, which is used to detect the status signal of the water tank. When the control sensor detects that the status signal of the water tank meets the first preset condition, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connectivity state.

[0098] Optionally, in this embodiment, the water level detection member or water pressure sensor 50 is linked to the external switch device 200 through the control sensor. The water level detection member or the water pressure sensor 50 is arranged in the water tank. The water level detection member or the water pressure sensor 50 is used to detect the water level or water pressure in the water tank, and when the water level or water pressure meets a first preset condition, send an open signal to the external switch device 200 to trigger the external switch device 200 to open the external water pipe 20 (in this embodiment, the first preset condition may be that the water level is lower than a preset water level, or the water pressure is not within a preset water pressure range); or when the water level or water pressure meets the first preset condition, send a close signal to the external switch device 200 to trigger the external switch device 200 to close the external water pipe 20 (in this embodiment, the first preset condition may be that the water level is higher than a preset water level, or the water pressure reaches a preset water pressure range). Optionally, the status signal of the water tank includes a water level signal or a water pressure signal.

[0099] This embodiment directly detects the water level of the water tank through the water level detection component, or detects the water pressure of the water tank through the water pressure sensor 50 to identify the water volume of the water tank. If the water volume in the water tank is low, the external switch device 200 is triggered to open the external water pipe 20 to replenish water to the water tank. Or when the water volume in the water tank is high, the external switch device 200 is triggered to close the external water pipe 20 to prevent the external water pipe 20 from leaking. Optionally, the switch valve 201 of the external switch device 200 can be a normally closed water valve 21. It can also be a normally open water valve 21. If the switch valve 201 is a normally open water valve 21, it is only necessary to trigger the water pump to start or close.

[0100] This embodiment directly controls the external switch device 200 by detecting the water level of the water tank, which can accurately obtain the water demand of the water tank and supply water in time. It can also avoid opening the external switch device 200 when there is sufficient water, and more effectively prevent external water pipe leakage.

[0101] As in the third embodiment, the status signal includes the status signal of the internal water pipe, the control sensor is connected to the internal water pipe, and the control sensor includes any one of a water pressure sensor 52, a flow sensor 50 and a flow velocity sensor 50, for detecting the status signal of the internal water pipe. When the control sensor detects that the status signal of the internal water pipe meets the second preset condition, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connectivity state.

[0102] Optionally, when the control sensor detects that the status signal of the internal water pipe meets a second preset condition, it sends an opening signal to the external switch device 200 to trigger the opening of the external switch device 200. In this embodiment, the second preset condition is that the internal water pipe has a water flow signal, or the water pressure in the internal water pipe reaches a preset water pressure.

[0103] Optionally, the control sensor may further send a closing signal to the external switch device 200 upon detecting that the status signal of the internal water pipe meets a second preset condition, thereby triggering the external switch device 200 to close the external water pipe 20. In this embodiment, the second preset condition is that the internal water pipe has no water flow signal, or the water pressure in the internal water pipe is less than a preset water pressure.

[0104] Optionally, the status signal of the internal water pipe in this embodiment may be a status signal of the first water pipe or the second water pipe.

[0105] This embodiment can obtain the water usage of the base station by detecting the status signal of the internal water pipe, and then trigger the external switch device 200 according to the water usage of the base station to change the conduction state of the external switch device 200.

[0106] If the status signal of the internal water pipe meets the water use condition, that is, there is flowing water in the internal water pipe, the base station uses water, and then the external switch device 200 is triggered to open to supply water to the base station, so as to avoid the use being affected by the lack of timely water supply after water use.

[0107] As in the fourth embodiment, the base station also includes a cleaning liquid supply device, the internal water channel structure includes an internal water pipe, the status signal includes a status signal of the internal water pipe, the internal water pipe is respectively connected to the cleaning liquid supply device and the control sensor, and the control sensor includes a current sensor 50 for detecting the status signal of the internal water pipe. When the control sensor detects that the status signal of the internal water pipe meets the third preset condition, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connectivity state.

[0108] Optionally, when the control sensor detects that the status signal of the internal water pipe meets the third preset condition, it sends an opening signal to the external switch device 200 to trigger the external switch device 200 to open.

[0109] Alternatively, when the control sensor detects that the status signal of the internal water pipe meets the third preset condition, it sends a closing signal to the external switch device 200 to trigger the external switch device 200 to close.

[0110] Optionally, the third preset condition may be that the current signal of the internal water pipe reaches a preset current value. Alternatively, the third preset condition may be that the current signal of the internal water pipe is less than a preset current value.

[0111] It is understandable that the cleaning liquid contains conductive substances. In this embodiment, the current sensor 50 is set to detect the current state in the internal water pipe between the cleaning liquid supply device and the cleaning tank of the base station. If the current is detected in the internal water pipe, such as the current value reaches a preset current value, it is determined that cleaning liquid is flowing in the internal water pipe. Cleaning liquid is generally transported from the cleaning liquid supply device to the cleaning tank only when operations such as cleaning the mop are started, and cleaning liquid will be present in the internal water pipe. Therefore, this embodiment can achieve timely water supply by detecting the status signal of the internal water pipe and triggering the external switch device 200 to open when the status signal meets the third preset condition. Alternatively, when the current value is less than the preset current value, it means that the cleaning liquid delivery is completed, and at this time, the external switch device 200 is triggered to open again.

[0112] Optionally, the external switch device 200 in this embodiment may be a normally closed water valve. This embodiment triggers the normally closed water valve to open based on the status signal of the internal water pipe, thereby realizing intelligent control of boiling water without the need for a normally open water source.

[0113] Alternatively, the external switch device 200 includes a normally open water valve. In this embodiment, when the control sensor detects that the status signal of the internal water pipe satisfies the third preset condition, a closing signal may be sent to the external switch device 200 to trigger the external switch device 200 to close. This is because when the cleaning liquid is being delivered, it indicates that the water in the base station water tank has been pumped into the cleaning tank, or the water in the water tank is being pumped into the cleaning tank. During the process of the water in the water tank being pumped away, the water source may have begun to supply water to the water tank. Therefore, to prevent leakage of the external water pipe 20, the external switch device 200 is triggered to close after the detergent is added or after the detergent addition is completed.

[0114] Optionally, the control sensor can also trigger the external switch device 200 to close when the status signal meets another preset condition, thereby timely shutting off the water and preventing water leakage. Optionally, meeting the other preset condition includes: detecting that the internal water pipe is in a state where no cleaning liquid is flowing, or detecting the status signal and continuing for a preset period of time.

[0115] Optionally, in another embodiment, the electronic control device is a controller 40 , and the controller 40 is used to obtain a status signal and send a control signal to the external switch device 200 .

[0116] In this embodiment, the base station also includes a functional component, the internal water channel structure includes a water tank and an internal water pipe, the electronic control device includes a controller 40, and the controller 40 is used to receive a status signal and also to send a control signal to the external switch device 200, wherein the status signal includes at least one of the status signal of the water tank, the status signal of the internal water pipe, the status signal of the external water pipe, and the working status signal of the functional component.

[0117] That is, in this embodiment, the external switch device 200 is controlled based on the controller 40 .

[0118] Optionally, the controller 40 can send a control signal to the external switch device 200 through any one or more of the water tank status signal, the internal water pipe status signal, the external water pipe status signal and the working status signal of the functional component to trigger the external switch device 200 to change the conduction state.

[0119] In the first embodiment, the controller 40 sends a control signal to the external switch device 200 based on the operating status of the functional component. In this embodiment, the base station further includes a functional component, and the status signal is a status signal of the functional component. When the controller 40 obtains a start signal or a stop signal from the functional component, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change its connection state. Alternatively, when the controller 40 receives a start signal or a stop signal from the functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open, and after a preset time period, sends a close signal to the external switch device 200 to trigger the external switch device 200 to close.

[0120] The functional components include a power pump or a mop drying component.

[0121] Optionally, when the controller 40 receives a working signal of a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open; or, when the controller 40 receives a signal that the functional component stops working, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close; or, when the controller 40 receives a working signal of a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open, and after a preset time is reached, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close. Alternatively, when the controller 40 receives a stop working signal from a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open; or when the controller 40 receives a stop working signal from a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open, and after a preset time period is reached, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close.

[0122] It can be understood that, in this embodiment, the controller 40 is used to realize the linkage control of the functional components and the external switch device 200 .

[0123] For example, when the controller 40 starts the functional component, it simultaneously controls the external switch device 200 to open the external water pipe 20 (in the scenario where the switch valve 201 of the external switch device 200 is a normally closed water valve 21). Alternatively, when the controller 40 controls the functional component to stop working, it simultaneously controls the external switch device 200 to close (the switch valve 201 of the external switch device 200 can be a normally closed water valve 21 or a normally open water valve 21), or when the controller 40 controls the functional component to stop working, it simultaneously controls the external switch device 200 to open. The controller 40 controls the external switch device 200 and the functional component in a linked manner, so that the external switch device 200 is opened when the functional component needs water to supply water to the cleaning base station. When the functional component finishes working or ends, the switch device 200 is closed to prevent the external water pipe 20 from leaking. Or water is replenished in time after work.

[0124] In the second embodiment, the controller 40 sends a control signal to the external switch device 200 based on the status signal of the external water pipe. Figure 11 and Figure 12 The external switch device 200 includes a switch valve 201 and a water flow state detection component. The water flow state detection component is connected to the base station and is used to detect the state of the external water pipe 20 and send the detected external water pipe state signal to the base station. The water flow state detection component includes at least one of a water meter, a water pressure detector 52, a water flow tachometer, and a timer 51. It is understandable that the state signal of the external water pipe varies based on the type of the water flow state detection component. For example, the state signal of the external water pipe includes water flow duration, water flow rate, water pressure, and water flow speed.

[0125] As in this embodiment, the water flow state detection component of the external switch device 200 sends the detected state signal of the external water pipe to the controller 40. When the state signal of the external water pipe satisfies the fourth preset condition, the controller 40 sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connectivity state.

[0126] When the controller 40 receives the status signal of the external water pipe sent by the external switch device 200, it determines whether a fourth preset condition is satisfied based on the status signal. If satisfied, it sends a closing signal to the external switch device 200 to close the external water pipe 20. Optionally, the fourth preset condition is set based on the corresponding state of the external water pipe 20 when the water tank is full during the water tank filling process.

[0127] The external water pipe status signal satisfies the fourth preset condition, which includes at least one of the following:

[0128] The duration of the water flow in the external water pipe being in the water flow state is greater than or equal to the preset water flow duration;

[0129] The water flow rate of the external water pipe reaches a preset threshold;

[0130] The water pressure of the external water pipe is different from the preset water pressure;

[0131] The water flow rate of the external water pipe is different from the preset water flow rate.

[0132] The preset water flow duration is the time required to fill the water tank with water. The preset threshold is the capacity of the water tank. The preset water pressure is the water pressure in the external water pipe 20 during the water tank filling process. The preset water flow rate is the water flow rate in the external water pipe 20 during the water tank filling process.

[0133] If the water flow time of the external water pipe 20 is greater than or equal to the preset water flow time, it means that the water tank is full of water. At this time, the switch valve 201 of the external switch device 200 is closed to close the external water pipe 20, which can prevent the external water pipe 20 from leaking.

[0134] Alternatively, the external water pipe 20 is in a water flow state, and the water flow rate is detected. If the water flow rate reaches a preset threshold, it means that the water tank has been filled with water. At this time, the switch valve 201 of the external switch device 200 is closed, so that the external water pipe 20 is closed, which can prevent the external water pipe 20 from leaking.

[0135] Alternatively, the water pressure of the external water pipe 20 is monitored in real time or periodically. If the water pressure remains at a preset pressure, it indicates that the external water pipe 20 is normally supplying water to the water tank. If the water pressure is lower than the preset pressure, or the difference between the preset pressure and the water pressure is large, it indicates that there is no need to supply water to the water tank. The on-off valve 201 of the external on-off device 200 is closed, thereby closing the external water pipe 20 and preventing water leakage.

[0136] Alternatively, the water flow rate of the external water pipe 20 is monitored in real time or periodically. If the water flow rate remains at a preset flow rate, it indicates that the external water pipe 20 is normally supplying water to the water tank. If the water flow rate is lower than the preset flow rate, or the difference between the preset flow rate and the water flow rate is large, it indicates abnormal water flow, such as leakage from the external water pipe 20. Closing the on-off valve 201 of the external on-off device 200 and promptly closing the external water pipe 20 can effectively prevent leakage from the external water pipe 20.

[0137] That is, by presetting the above-mentioned preset conditions, when the controller 40 receives the status signal of the external water pipe sent by the external switch device 200, it compares the status signal with the preset conditions. If the status signal meets the preset conditions, it sends a closing signal to the external switch device 200 to close the external water pipe 20, thereby achieving automatic control of water leakage prevention of the external water pipe 20.

[0138] In another embodiment, the electronic control device includes a controller 40 and a sensor 50, and the controller 40 is connected to the sensor 50. The controller 40 sends a control signal to the external switch device 200 based on the state signal detected by the sensor 50, so as to trigger the external switch device 200 to change the conduction state.

[0139] As in the first embodiment, the status signal is a working status signal of a functional component. If the functional component includes a power pump or a mop drying component, the electronic control device further includes a sensor 50, which is used to detect the working status signal of the functional component and transmit the working status signal to the controller 40 to trigger the external switch device 200 to change the connection state.

[0140] For example, when the controller 40 receives a working signal of a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open; or, when the controller 40 receives a stop working signal of the functional component, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close; or, when the controller 40 receives a start working signal or a stop working signal of a functional component, it sends an open signal to the external switch device 200 to trigger the external switch device 200 to open, and after a preset time is reached, it sends a close signal to the external switch device 200 to trigger the external switch device 200 to close.

[0141] Optionally, in this embodiment, the functional components of the base station are controlled in conjunction with the external switch device 200 via the sensor 50 and the controller 40. The sensor 50 detects an on-operation signal or an off-operation signal of the functional component. The controller 40 sends a control signal to the external switch device 200 based on the status signal detected by the sensor 50, triggering the external switch device 200 to open the external water pipe 20, thereby connecting the external water pipe 20 to the water tank and supplying water to the base station. Alternatively, the external switch device 200 is triggered to close the external water pipe 20, thereby stopping the water supply to the base station and preventing water leakage in the pipe section between the external water pipe 200 and the base station.

[0142] For example, when the functional component is started, the sensor 50 can detect the start signal of the functional component, and the controller 40 triggers the external switch device 200 to open the external water pipe 20 based on the start signal detected by the sensor 50 (in the scenario where the switch valve 201 of the external switch device 200 is a normally closed water valve 21). Alternatively, when the functional component stops working, the sensor 50 can detect the stop working signal of the functional component, and the controller triggers the external switch device 200 to close based on the stop working signal detected by the sensor 50 (the switch valve 201 of the external switch device 200 can be a normally closed water valve 21 or a normally open water valve 21). The linkage control between the external switch device 200 and the functional component is realized by the sensor 50 and the controller 40, so that the external switch device 200 is opened when the functional component needs water to supply water to the base station. When the functional component stops working or ends, the switch device 200 is closed to prevent water leakage from the external water pipe 20.

[0143] Optionally, in other embodiments, the sensor 50 may also send an opening signal to the external switch device 200 when receiving a stop signal from the functional component, so as to trigger the external switch device 200 to open the external water pipe after the functional component finishes working.

[0144] Alternatively, as in the second embodiment, the status signal is a status signal of a water tank. For example, the electronic control device further includes a sensor 50, which is a water level detection member 52 or a water pressure sensor 50 located in the water tank, for detecting the status signal of the water tank and sending the status signal of the water tank to the controller 40. When the controller 40 determines that the status signal satisfies a first preset condition, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connection state.

[0145] Optionally, in this embodiment, the component that is linked to the external switch device 200 through the sensor 50 and the controller 40 is a water level detection member or a water pressure sensor 50. The water level detection member or the water pressure sensor 50 is disposed in the water tank. The water level detection member or the water pressure sensor 50 is used to detect the water level or water pressure in the water tank and, when the water level or water pressure meets a first preset condition, send an open signal to the external switch device 200 to trigger the external switch device 200 to open the external water pipe 20 (in this embodiment, the first preset condition may be that the water level is lower than a preset water level, or that the water pressure is not within a preset water pressure range); or, when the water level or water pressure meets the first preset condition, send a close signal to the external switch device 200 to trigger the external switch device 200 to close the external water pipe 20 (in this embodiment, the first preset condition may be that the water level is higher than a preset water level, or that the water pressure reaches a preset water pressure range). Optionally, the status signal of the water tank includes a water level signal or a water pressure signal.

[0146] This embodiment directly detects the water level of the water tank through the water level detection part, or detects the water pressure of the water tank through the water pressure sensor 50 to identify the water volume of the water tank. If the water volume in the water tank is low, the external switch device 200 is triggered to open the external water pipe 20 to replenish water to the water tank. Or when the water volume in the water tank is high, the external switch device 200 is triggered to close the external water pipe 20 to avoid water leakage in the external water pipe. Optionally, the switch valve 201 of the external switch device 200 can be a normally closed water valve 21. It can also be a normally open water valve 21. If the switch valve 201 is a normally open water valve 21, it is only necessary to trigger the water pump to start or close.

[0147] This embodiment directly controls the external switch device 200 by detecting the water level of the water tank, which can accurately obtain the water demand of the water tank and supply water in time. It can also avoid opening the external switch device 200 when there is sufficient water, and more effectively prevent the external water pipe 20 from leaking.

[0148] Optionally, in a third embodiment, the status signal is a status signal of the internal water pipe. For example, the electronic control device further includes a sensor 50 connected to the internal water pipe. The sensor 50 includes any one of a water pressure sensor 50, a flow sensor 50, and a flow velocity sensor 50, for detecting the status signal of the internal water pipe and transmitting the status signal of the internal water pipe to the controller 40. When the controller 40 determines that the status signal of the internal water pipe satisfies a second preset condition, it transmits a control signal to the external switch device 200 to trigger the external switch device 200 to change the connection state.

[0149] Optionally, after the sensor 50 detects a status signal from the internal water pipe, it transmits it to the controller 40. After the controller 40 determines that a second preset condition has been satisfied based on the status signal from the internal water pipe, it transmits an opening control signal to the external switch device 200 to trigger the external switch device 200 to open. In this embodiment, the second preset condition is a water flow signal from the internal water pipe, or the water pressure in the internal water pipe reaches a preset pressure.

[0150] Optionally, the sensor 50 may further send a closing signal to the external switch device 200 upon detecting that the status signal of the internal water pipe meets a second preset condition, thereby triggering the external switch device 200 to close the external water pipe 20. In this embodiment, the second preset condition is that the internal water pipe has no water flow signal, or the water pressure in the internal water pipe is less than a preset water pressure.

[0151] Optionally, the internal water pipe includes a first water pipe communicating with the external water pipe and a second water pipe communicating with each functional component. In this embodiment, the status signal of the internal water pipe may be a status signal of the first water pipe or the second water pipe.

[0152] This embodiment can obtain the water usage of the base station by detecting the status signal of the internal water pipe, and then trigger the external switch device according to the water usage of the base station to change the conductive state of the external switch device.

[0153] If the status signal of the internal water pipe meets the water use condition, that is, there is flowing water in the internal water pipe, the base station uses water, and then the external switch device 200 is triggered to open to supply water to the base station, so as to avoid the use being affected by the lack of timely water supply after water use.

[0154] Optionally, in a fourth embodiment, the internal water pipe status signal may further include a status signal of a water pipe between a cleaning liquid supply device and a cleaning tank of the base station. If the base station further includes a cleaning liquid supply device, the electronic control device further includes a sensor 50, and the internal water pipe is connected to the cleaning liquid supply device and the sensor 50, respectively. The sensor 50 includes a current sensor 50 for detecting the status signal of the internal water pipe and transmitting the internal water pipe signal to the controller 40. When the controller 40 determines that the internal water pipe status signal satisfies a third preset condition, it transmits a control signal to the external switch device 200 to trigger the external switch device 200 to change the connection state.

[0155] Optionally, the sensor 50 detects the status signal of the internal water pipe and sends the status signal of the internal water pipe to the controller 40. When the controller 40 determines that the status signal of the internal water pipe meets the third preset condition, it sends an opening signal to the external switch device 200 to trigger the external switch device 200 to open.

[0156] Alternatively, the sensor 50 detects the status signal of the internal water pipe and sends the status signal of the internal water pipe to the controller 40. When the controller 40 meets the third preset condition, it sends a closing signal to the external switch device 200 to trigger the external switch device 200 to close.

[0157] Optionally, the third preset condition may be that the current signal of the water pipe reaches a preset current value. Alternatively, the third preset condition may be that the current signal of the water pipe is less than a preset current value.

[0158] It is understandable that the cleaning liquid contains conductive substances. In this embodiment, the current sensor 50 is set to detect the current state in the internal water pipe between the cleaning liquid supply device and the cleaning tank of the base station. If the current is detected in the internal water pipe, such as the current value reaches a preset current value, it is determined that cleaning liquid is flowing in the internal water pipe. Cleaning liquid is generally transported from the cleaning liquid supply device to the cleaning tank only when the cleaning mop and other components are started, and cleaning liquid will be present in the internal water pipe. Therefore, this embodiment can achieve timely water supply by detecting the status signal of the internal water pipe and triggering the external switch device 200 to open when the status signal meets the third preset condition. Alternatively, when the current value is less than the preset current value, it means that the cleaning liquid delivery is completed, and at this time, the external switch device 200 is triggered to open again.

[0159] Optionally, the external switch device 200 in this embodiment may be a normally closed water valve. This embodiment triggers the normally closed water valve to open based on the status signal of the internal water pipe, thereby realizing intelligent control of boiling water without the need for a normally open water source.

[0160] Alternatively, the external switch device 200 includes a normally open water valve. In this embodiment, when the sensor 50 detects the status signal of the internal water pipe and the controller 40 determines that the status signal of the internal water pipe satisfies the third preset condition, a closing signal may be sent to the external switch device 200 to trigger the external switch device 200 to close. This is because when the cleaning liquid is being delivered, it indicates that the water in the base station water tank has been pumped into the cleaning tank, or the water in the water tank is being pumped into the cleaning tank. During the process of the water in the water tank being pumped away, the water source may have begun to supply water to the water tank. Therefore, to prevent leakage in the external water pipe, the external switch device 200 is triggered to close after the detergent is added or after the detergent addition is completed.

[0161] Optionally, the controller 40 can also trigger the external switch device 200 to close when the status signal meets another preset condition, thereby timely shutting off the water and preventing water leakage. Optionally, meeting the other preset condition includes: detecting that the internal water pipe is in a state where no cleaning liquid is flowing, or detecting the status signal and continuing for a preset period of time.

[0162] Optionally, in the fourth embodiment, the status signal may also be a status signal of an external water pipe. In this embodiment, the electronic control device further includes a sensor 50, which is connected to the external water pipe 20. The sensor 50 includes any one of a water pressure sensor 50, a flow sensor 50, and a flow velocity sensor 50, for detecting the status signal of the external water pipe and sending the status signal of the external water pipe to the controller 40. When the controller 40 determines that the status signal of the external water pipe meets a fourth preset condition, it sends a control signal to the external switch device 200 to trigger the external switch device 200 to change the connection state.

[0163] Optionally, when the controller 40 receives a status signal detected by the sensor 50 in communication with the external water pipe 20, it determines based on the status signal whether the status of the external water pipe satisfies a fourth preset condition, and if so, sends a shutoff signal to the external switch device 200 to shut off the external water pipe 20. Optionally, the preset condition is set based on the status of the external water pipe 20 corresponding to when the water tank is full during the water tank filling process.

[0164] The external water pipe status signal satisfies the fourth preset condition, which includes at least one of the following:

[0165] The duration of the water flow in the external water pipe being in the water flow state is greater than or equal to the preset water flow duration;

[0166] The water flow rate of the external water pipe reaches a preset threshold;

[0167] The water pressure of the external water pipe is different from the preset water pressure;

[0168] The water flow rate of the external water pipe is different from the preset water flow rate.

[0169] The preset water flow duration is the time required to fill the water tank with water. The preset threshold is the capacity of the water tank. The preset water pressure is the water pressure in the external water pipe 20 during the water tank filling process. The preset water flow rate is the water flow rate in the external water pipe 20 during the water tank filling process.

[0170] If the water flow time of the external water pipe 20 is greater than or equal to the preset water flow time, it means that the water tank is full of water. At this time, the switch valve 201 of the external switch device 200 is closed to close the external water pipe 20, which can prevent the external water pipe 20 from leaking.

[0171] Alternatively, the external water pipe 20 is in a water flow state, and the water flow rate is detected. If the water flow rate reaches a preset threshold, it means that the water tank has been filled with water. At this time, the switch valve 201 of the external switch device 200 is closed, so that the external water pipe 20 is closed, which can prevent the external water pipe 20 from leaking.

[0172] Alternatively, the water pressure of the external water pipe 20 is monitored in real time or periodically. If the water pressure remains at a preset pressure, it indicates that the external water pipe 20 is normally supplying water to the water tank. If the water pressure is lower than the preset pressure, or the difference between the preset pressure and the water pressure is large, it indicates that there is no need to supply water to the water tank. The on-off valve 201 of the external on-off device 200 is closed, thereby closing the external water pipe 20 and preventing water leakage.

[0173] Alternatively, the water flow rate of the external water pipe 20 is monitored in real time or periodically. If the water flow rate remains at a preset flow rate, it indicates that the external water pipe 20 is normally supplying water to the water tank. If the water flow rate is lower than the preset flow rate, or the difference between the preset flow rate and the water flow rate is large, it indicates abnormal water flow, such as leakage from the external water pipe 20. Closing the on-off valve 201 of the external on-off device 200 and promptly closing the external water pipe 20 can effectively prevent leakage from the external water pipe 20.

[0174] That is, by presetting the fourth preset condition, when the controller 40 receives the status signal detected by the sensor 50, it compares the status signal with the preset condition. If the status signal satisfies the fourth preset condition, it sends a closing signal to the external switch device 200 to close the external water pipe 20, thereby achieving automatic control of water leakage prevention of the external water pipe 20.

[0175] Alternatively, in some embodiments, the electronic control device controls the external switch device 200 to open each time it detects that the functional component is turned on, thereby regularly supplying water to the cleaning base station. Upon detecting that the external water pipe status satisfies a fourth preset condition, the external switch device 200 is closed to prevent water leakage from the external water pipe 20. It is understood that the electronic control device can trigger the external switch device 200 to open upon detecting that the functional component is turned on. Alternatively, the electronic control device can trigger the external switch device 200 to open after detecting that the functional component has been turned on for a period of time (e.g., after the functional component has completed operation, or after a preset operating time). The control time of the external switch device 200 can vary depending on the settings.

[0176] In this embodiment, the external switch device 200 may be a normally closed switch device 200. The functional components cooperatively control the external switch device 200 to open the external water pipe 20, while the electronic control device 40 controls the external switch device 200 to close the external water pipe 20 based on the status of the external water pipe 20. For example, the electronic control device 40 controls the functional components to activate and transmits an open signal to the external switch device 200 to trigger the external switch device 200 to open the external water pipe 20. When the electronic control device 40 receives the external water pipe status transmitted by the external switch device and the external water pipe status satisfies the fourth preset condition, it transmits a close signal to the external switch device 200 to trigger the external switch device 200 to close the external water pipe 20. In this embodiment, the functional components cooperatively control the switch device 200 to open the external water pipe 20 to supply water to the cleaning base station, while the external switch device 200 controls the switch device 200 to close based on the detection signal transmitted by the external switch device 200. This ensures timely water replenishment to the water tank while effectively preventing leakage from the external water pipe 20.

[0177] Alternatively, in some embodiments, the electronic control device can trigger the external switch device 200 to perform different actions based on different types of status signals. For example, the electronic control device triggers a signal to open or close the external switch device 200 based on the working status of the functional component. Alternatively, the electronic control device triggers the external switch device 200 to open the external water pipe 20 based on the status signal of the internal water pipe, and triggers the external switch device 200 to close the external water pipe 20 based on the status signal of the external water pipe 20; or the electronic control device triggers the external switch device 200 to open the external water pipe 20 based on the status signal of the internal water pipe, and triggers the external switch device 200 to close the external water pipe 20 based on the working signal of the functional component (for example, when the mop drying component is activated, it means that the mop has been washed and the water has been used for a period of time).

[0178] Optionally, the functional components in all the above embodiments include but are not limited to a power pump, a mop drying component, etc.

[0179] The power pump includes any one of a cleaning pump, a sewage pump and a peristaltic pump. The base station includes a cleaning tank, and the cleaning pump is arranged between the cleaning tank and the water tank; or, a drain pipe is provided on the cleaning tank, and the sewage pump is arranged in the drain pipe; or, the peristaltic pump is connected to the cleaning tank for adding detergent to the cleaning tank.

[0180] For example, when the cleaning pump is activated, water needs to be supplied to the cleaning tank. After the water in the water tank is delivered to the cleaning tank, the water tank needs to be replenished promptly. Therefore, the external switch device 200 is controlled to open the external water pipe 20 to replenish the water tank. Optionally, the switch valve 201 of the external switch device 200 is a normally closed water valve 21. If it is a normally open water valve 21, only the water pump needs to be turned on. After the clean water pump has finished operating, or when the external water pipe status meets preset conditions, the external switch device 200 is closed.

[0181] When the sewage pump is started, the sewage in the cleaning tank will be discharged to the floor drain or drain. When the sewage pump is started, it means that the cleaning robot is performing cleaning work. At this time, the water in the water tank has been drained, and water needs to be added to the water tank in time. Therefore, the external switch device 200 is linked to control the opening of the external water pipe 20 to add water to the water tank. Optionally, the switch valve 201 of the external switch device 200 is a normally closed water valve 21. If it is a normally open water valve 21, it is only necessary to turn on the water pump. After the sewage pump finishes working, or when the state of the external water pipe 20 meets the preset conditions, the external switch device 200 is closed.

[0182] If the peristaltic pump is activated, it indicates that the cleaning robot needs to perform cleaning work and requires water. The water in the water tank is already in the cleaning trough, waiting to be used to clean the mop, etc., and the water tank needs to be replenished in a timely manner. Therefore, the external switch device 200 is controlled to open the external water pipe 20 to replenish the water tank. Optionally, the switch valve 201 of the external switch device 200 is a normally closed water valve 21. If it is a normally open water valve 21, only the water pump needs to be turned on. When the status of the external water pipe 20 meets the preset conditions, the external switch device 200 is closed.

[0183] It should be noted that the peristaltic pump is used to drive the detergent to the cleaning tank. Therefore, the peristaltic pump is generally started when cleaning components such as mops. Each time the peristaltic pump is started, it indicates that the water in the driving water tank has been pumped into the cleaning tank.

[0184] Optionally, the mop drying component includes at least one of a fan and a heating module. If the mop drying component is started, it means that the mop has been cleaned. At this time, the water in the water tank has been used to clean the mop, and the water in the water tank needs to be replenished in time. Therefore, the external switch device 200 is linked to control the opening of the external water pipe 20 to replenish water to the water tank. Optionally, the switch valve 201 of the external switch device 200 is a normally closed water valve 21. If it is a normally open water valve 21, it is only necessary to turn on the water pump. After the mop drying component finishes working, or when the state of the external water pipe 20 meets the preset conditions, the external switch device 200 is closed.

[0185] In this embodiment, the electronic control device of the base station can obtain a status signal, such as detecting or receiving the status signal, and based on the status signal, send a signal to the external switch device 200, causing the external switch device to change its connection state according to the signal, thereby controlling the conduction or closure of the external water pipe 20 where the external switch device 200 is located. In this way, the external valve can be automatically opened when water is needed to supply water to the base station, or the valve can be automatically closed when water is not needed, thereby preventing leakage from the external water pipe 20 when the faucet is always open.

[0186] Optionally, based on the structure of the above base station, the present invention provides a base station control method, please refer to Figure 13 , the base station control method includes:

[0187] Step S10, the electronic control device obtains a trigger signal;

[0188] Step S20: sending a control signal to the external switch device, so that the external switch device changes the connection state according to the control signal.

[0189] The base station in this embodiment is the base station described in the above embodiments.

[0190] The base station includes an electronic control device. The electronic control device can be exposed to a state signal, wherein the trigger signal includes a time signal or a state signal.

[0191] Optionally, the time signal is a water supply time signal or a water shutoff time signal set in the base station. The time signal can be set by the user or based on the water usage time or water usage frequency of the base station. The base station can automatically generate the time signal based on the timing setting, so that the electronic control device receives the time signal and triggers the external switch device.

[0192] Optionally, the status signal includes at least one of a water tank status signal, an internal water pipe status signal, an external water pipe status signal, and a working status signal of the functional component. In this embodiment, the triggering process of the electronic control device is described below using the status signal as an example.

[0193] When the electronic control device receives the status signal, it sends a control signal to the external switch device according to the status signal, so that the external switch device changes the connection state according to the control signal.

[0194] Optionally, in one embodiment, the electronic control device may receive multiple status signals, and then trigger the external switch device based on the multiple status signals.

[0195] In this embodiment, the types of status signals vary, and the types of signals sent by the electronic control device to the external switch device vary. The step of sending a signal to the external switch device includes determining the type of status signal and sending a signal corresponding to the status type to the external switch, causing the external switch device to change its connection state in accordance with the control signal. It should be noted that the types of signals sent by the electronic control device to the external switch device include open signals and close signals. Upon receiving the open signal, the external switch device changes its state to a connected state, thereby opening the external water pipe. Upon receiving the close signal, the external switch device changes its state to a disconnected state, thereby closing the external water pipe.

[0196] Optionally, when the status signal is a water tank status signal, an internal water pipe status signal, or a working status signal of a functional component, an open signal is sent to the external switching device accordingly; when the status signal is a working status signal of a functional component or the external water pipe status signal, a close signal is sent to the external switching device accordingly.

[0197] Optionally, the step of sending a control signal corresponding to the type to the external switch device so that the external switch device changes the connection state according to the control signal includes:

[0198] When the state signal is a start signal of the functional component, an opening signal is sent to the external switch device;

[0199] When the status signal is an external water pipe status signal and the external water pipe signal meets a preset condition, a closing signal is sent to the external switch device.

[0200] Alternatively, in another embodiment, the electronic control device can receive only one type of status signal, namely, the status signal includes any one of a water tank status signal, an internal water pipe status signal, an external water pipe status signal, and an operating status signal of the functional component. Based on the status signal, the electronic control device sends a control signal to the external switch device to trigger the external switch device to close or open the external water pipe.

[0201] In one embodiment, the step of sending a control signal to the external switch device so that the external switch device changes the connection state according to the control signal includes:

[0202] The state signal is an external water pipe state signal, and when the received external water pipe state signal satisfies a fourth preset condition, a control signal is sent to the external switch device so that the external switch device changes the connection state according to the control signal;

[0203] When the external water pipe status signal does not meet the preset condition, the external water pipe status signal is not responded to.

[0204] In one embodiment, when the status signal is an external water pipe status signal, the electronic control device determines whether a fourth preset condition is met based on the external water pipe status signal after receiving the external water pipe status signal. If so, it means that the water supply shutoff condition is met, and a shutoff signal is sent to the external switch device to cause the external switch device to shut off the external water pipe.

[0205] Optionally, the external water pipe status signal satisfies a fourth preset condition including at least one of the following:

[0206] The water flow time duration of the external water pipe in the water flow state is greater than the first preset water flow time duration;

[0207] The water flow rate of the external water pipe reaches the preset threshold;

[0208] The water pressure of the external water pipe is different from the preset water pressure;

[0209] The water flow rate in the external water pipe is different from the preset water flow rate.

[0210] The first preset water flow duration is the time required to fill the water tank with water. The preset threshold is the capacity of the water tank. The preset water pressure is the water pressure in the water pipe during the water tank filling process. The preset water flow rate is the water flow rate in the water pipe during the water tank filling process.

[0211] If the water flow time of the water pipe is greater than or equal to the first preset water flow time, it means that the water tank is full of water. At this time, the switch valve of the external switch device is closed to close the water pipe, which can prevent water leakage.

[0212] Alternatively, the water pipe is in a water flow state, and the water flow is detected. If the water flow reaches a preset threshold, it means that the water tank is full of water. At this time, the switch valve of the external switch device is closed to close the water pipe, which can prevent water leakage.

[0213] Alternatively, the water pressure of the water pipe is detected in real time or at regular intervals. If the water pressure remains at a preset pressure, it indicates that the water pipe is normally supplying water to the water tank. If the water pressure is lower than the preset pressure, or the difference between the preset pressure and the water pressure is large, it indicates that there is no need to supply water to the water tank. The on-off valve of the external switch device is closed to close the water pipe and prevent water leakage.

[0214] Alternatively, the water flow rate of the water pipe can be monitored in real time or at regular intervals. If the water flow rate remains at a preset flow rate, it indicates that the water pipe is normally supplying water to the water tank. If the water flow rate is lower than the preset flow rate, or the difference between the preset flow rate and the water flow rate is large, it indicates abnormal water flow, such as a water pipe leak. Closing the on-off valve of the external switch device and promptly closing the water pipe can effectively prevent the leak.

[0215] This embodiment automatically controls the external switch device to close by using the external water pipe status signal. When the water in the water tank is full or there is a water leak in the external water pipe, the external switch device is controlled to close to close the external water pipe, thereby preventing water leakage in a timely manner.

[0216] Optionally, as in another embodiment, the step of sending a control signal to the external switch device so that the external switch device changes the connection state according to the control signal includes:

[0217] The status signal is the working status signal of the functional component. When the working status signal of the functional component is received, an opening control signal is sent to the external switching device; and / or, when the working status signal of the functional component is obtained, a control signal is sent to the external switching device after a first preset time interval to trigger the external switching device to change the connectivity state. The working status signal of the functional component includes a start signal or a stop working signal.

[0218] Optionally, upon receiving a start signal from a functional component, an on signal is sent to the external switch device; or upon receiving a shut-down signal from a functional component, a shut-down signal is sent to the external switch device; or upon receiving a shut-down signal from the functional component, an on signal is sent to the external switch device.

[0219] Optionally, in this embodiment, the switch valve of the external switch device is a normally closed water valve. When the base station uses water, the switch valve of the external switch device is opened to open the water pipe and supply water to the cleaning base station. Alternatively, when the base station finishes using water or the water tank is full, the external switch device is closed to close the external water pipe.

[0220] Optionally, in some embodiments, after receiving the stop working signal of the functional component, and after a first preset time interval, or recording the water flow time of the water pipe, when the water flow time is greater than or equal to a second preset water flow time, a closing signal is sent to the external switching device to trigger the external switching device to close, wherein the water pipe includes an external water pipe and an internal water pipe.

[0221] After receiving the stop signal from the functional component, the device sends the shutdown signal to the external switch device to trigger the external switch device to shut down after a first preset duration or after the water flow duration in the water pipe is greater than or equal to a second preset water flow duration. In scenarios where the functional component on duration and the water tank water filling duration are different, this embodiment triggers the external switch device to shut down after receiving the stop signal from the functional component and then after the first preset duration or the second preset water flow duration has passed, thereby meeting the water tank's water filling requirement.

[0222] In this embodiment, when the functional component is activated, the controller controls the external switch device to trigger the external switch device to open the water pipe. When a normally closed water valve is installed on the water pipe, the switch device can also be automatically controlled to automatically add water to the water tank, thereby preventing water leakage when the water pipe does not need to add water to the water tank.

[0223] Optionally, in another embodiment, the electronic control device can receive multiple status signals, and send different signals based on different reception times of the status signals.

[0224] The step of sending a control signal to the external switch device so that the external switch device changes the connection state according to the control signal comprises:

[0225] Upon receiving a working status signal of the functional component, sending an opening signal to the external switching device;

[0226] After an interval of a second preset time, or when the received external water pipe status signal meets a fourth preset condition, a closing signal is sent to the external switching device to trigger the external switching device to close, and the working status signal of the functional component includes a start working signal or a stop working signal.

[0227] When the electronic control device receives the start signal of the functional component, it sends an opening signal to the external switch device, and the external switch device opens the external water pipe, and the water source supplies water to the base station.

[0228] During the water supply process, after a second preset time interval, or when the external water pipe status signal is received, it is determined whether the external water pipe status signal meets a fourth preset condition. If so, it means that the water supply is completed. At this time, a closing signal is sent to the external switch device to trigger the external switch device to close the external water pipe.

[0229] That is, the external switch device is controlled to open by the activation signal of the functional component, without the need to set a normally open water source. The external switch device is automatically triggered to close by the status signal of the external water pipe, which can better prevent the external water pipe from leaking.

[0230] That is, by presetting the fourth preset condition, when the controller receives a status signal sent by the trigger component of the external switch device, it compares the status signal with the fourth preset condition. If the status satisfies the fourth preset condition, it sends a closing signal to the external switch device to close it, thereby achieving automatic control of water leakage prevention of the water pipe.

[0231] In this embodiment, the electronic control device of the base station can obtain a status signal, such as detecting or receiving the status signal, and based on the status signal, send a control signal to the external switch device, causing the external switch device to change its connection state according to the control signal, thereby controlling the opening or closing of the external water pipe where the external switch device is located. In this way, the external locking device can be automatically opened when water is needed to supply water to the base station, or the valve can be automatically closed when water is not needed, thereby preventing leakage from the external water pipe when the faucet is always open. In this way, through preset conditions or the linkage between the opening and closing of functional components and the switch device, the valve can be automatically closed when water is not needed, thereby preventing leakage from the water pipe when the faucet is always open.

[0232] Optionally, the present invention also proposes a water supply system, which includes a switching device and the base station as described above, the external switching device is actively or passively connected to the base station, the water tank of the base station is connected to the water source through an external water pipe, and the external switching device is connected to the external water pipe.

[0233] Optionally, in a first embodiment of the water supply system, the water supply system 100 includes a water delivery device 10, an external water pipe 20 and a water-using device 30, the water inlet end of the external water pipe 20 is connected to the water delivery device 10, and the water outlet end of the external water pipe 20 is connected to the water-using device 30, so that the water delivery device 10 supplies water to the water-using device 30 through the external water pipe 20, and the water-using device 30 is used to clean the cleaning robot; the water supply system 100 also includes a controller 40 and a detection component 50, a normally open water valve 21 is provided on the external water pipe 20, the detection component 50 is used to detect the fluid state in the external water pipe 20, and the controller 40 is used to control the normally open water valve 21 to be closed when the detection component 50 detects that the fluid state in the external water pipe 20 meets the preset conditions.

[0234] It should be noted that the water supply system 100 can be used in a cleaning system, which includes a cleaning base station and a cleaning robot. The cleaning robot is provided with a mop, which needs to be cleaned with water after being used for a period of time. The cleaning base station has a mop cleaning device for cleaning the mop. The cleaning base station may be provided with a water tank or not. The water supply device 30 may be a cleaning base station, and the water supply device 10 may be a faucet that supplies water to the cleaning base station, and the faucet is a normally open faucet.

[0235] like Figures 1 to 4 As shown, the water delivery device 10 is used to communicate with an external water source. The water delivery device 10 and the water-using device 30 are connected through an external water pipe 20, so that the external water source can flow into the external water pipe 20 through the water delivery device 10, and then flow into the water-using device 30 from the external water pipe 20. At this time, the water supply system 100 is in a water supply state. In the water supply state, the fluid in the external water pipe 20 is in a flowing state, and the normally open water valve 21 is provided on the external water pipe 20 near the water delivery device 10. In the normal state of the water supply system 100, when the cleaning robot needs to wash the mop at the cleaning base station, that is, when the water-using device 30 needs water, the external water source can flow into the water-using device 30 through the water delivery device 10 and the external water pipe 20, and the fluid in the external water pipe 20 is in a flowing state. The cleaning robot can wash the mop at the cleaning base station; when the mop is washed or there is no need to wash the mop, that is, when there is no need to supply water to the water-using device 30, the fluid in the external water pipe 20 is in a non-flowing state. Furthermore, the amount of water used by the water-using device 30 is fixed each time. When the amount of water flowing into the water-using device 30 reaches the water volume used once, the water in the external water pipe 20 cannot enter the water-using device 30, i.e., the fluid in the external water pipe 20 changes from a flowing state to a non-flowing state. The time required for the water volume in the water-using device 30 to reach the water volume used once is the preset flow time. Furthermore, it is understood that when the water supply system 100 is in a seepage or leakage state, the fluid in the external water pipe 20 is also in a flowing state. That is, the fluid in the external water pipe 20 is in a flowing state, including but not limited to the water supply state, seepage state, and leakage state of the water supply system 100.

[0236] In one embodiment, when the fluid in the external water pipe 20 is in a flowing state supplied by the water-using equipment, the water pressure in the external water pipe 20 is P1; when the fluid in the external water pipe 20 is in a non-flowing state, the water pressure in the external water pipe 20 is P2, wherein the preset condition is that the water pressure in the external water pipe 20 is P1 or P2, and the detection component 50 is used to detect the fluid state in the external water pipe 20. When the detection component 50 detects that the water pressure in the external water pipe 20 is not P1 or P2, it is determined that the water supply system 100 may have a leak. At this time, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot pass through the external water pipe 20, thereby preventing water leakage. The water supply system 100 has the advantages of good leak-proof performance, stability and reliability, and improves the user experience.

[0237] In another embodiment, when the fluid in the external water pipe 20 is in a flowing state to supply water to the water-using device, the water pressure in the external water pipe 20 is P1; when the fluid in the external water pipe 20 is in a non-flowing state, the water pressure in the external water pipe 20 is P2, and P1 < P2; wherein, the preset condition is that the duration of the water pressure in the external water pipe 20 being P1 is greater than the preset flowing duration, that is, the preset condition is that the actual flowing duration is greater than the preset flowing duration. The detection component 50 is used to detect the fluid state in the external water pipe 20. When the duration detected by the detection component 50 that the water pressure in the external water pipe 20 is P1 exceeds the preset flowing duration, it is determined that the water supply system 100 may be leaking. At this time, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot pass through the external water pipe 20, playing a role in preventing water leakage. The water supply system 100 has the advantages of good leak prevention performance, stability and reliability, and improves the user experience.

[0238] In yet another embodiment, when the fluid in the external water pipe 20 is in a flowing state to supply water to the water-using device, the water flow rate in the external water pipe 20 is s1; when the fluid in the external water pipe 20 is in a non-flowing state, the water flow rate in the external water pipe 20 is s2; wherein, the preset condition is that the water flow rate in the external water pipe 20 is s1 or s2. The detection component 50 is used to detect the fluid state in the external water pipe 20. When the detection component 50 detects that the water flow rate in the external water pipe 20 is not s1 or s2, it is determined that the water supply system 100 may be leaking. At this time, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot pass through the external water pipe 20, playing a role in preventing water leakage. The water supply system 100 has the advantages of good leak prevention performance, stability and reliability, and improves the user experience.

[0239] In yet another embodiment, when the fluid in the external water pipe 20 is in a flowing state to supply water to the water-using device, the water flow rate in the external water pipe 20 is s1; when the fluid in the external water pipe 20 is in a non-flowing state, the water flow rate in the external water pipe 20 is s2, and s2 = 0 < s1; wherein, the preset condition is that the duration of the water flow rate in the external water pipe 20 being s1 is greater than the preset flowing duration, that is, the preset condition is that the actual flowing duration is greater than the preset flowing duration. The detection component 50 is used to detect the fluid state in the external water pipe 20. When the duration detected by the detection component 50 that the water flow rate in the external water pipe 20 is s1 exceeds the preset flowing duration, it is determined that the water supply system 100 may be leaking. At this time, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot pass through the external water pipe 20, playing a role in preventing water leakage. The water supply system 100 has the advantages of good leak prevention performance, stability and reliability, and improves the user experience.

[0240] In this embodiment, the detection component 50 is used to detect the actual flow time of the fluid in the external water pipe 20 when it is in a flowing state, and the controller 40 is used to control the normally open water valve 21 to be closed when the detection component 50 detects that the actual flow time is longer than the preset flow time. Figures 1 to 4 As shown, the preset flow time is the time required for the water volume in the water-using equipment 30 to reach the water volume for one time when supplying water to the water-using equipment under normal conditions; the detection component 50 starts to measure the actual flow time when the fluid in the external water pipe 20 is in a flowing state. When the detection component 50 detects that the actual flow time is greater than the preset flow time, it is determined that the water supply system 100 may have a leak. At this time, the controller 40 controls the normally open water valve 21 to close, effectively preventing the water supply system 100 from leaking.

[0241] In this embodiment, the detection component 50 includes a timer 51. The timer 51 and the normally open water valve 21 are both connected to the controller 40 for communication. The timer 51 is used to measure the actual flow time when the fluid in the external water pipe 20 is in a flowing state. Figures 1 to 4 As shown, the timer 51 is communicated with the controller 40, and the controller 40 is communicated with the normally open water valve 21. The timer 51 starts to measure the actual flow time when the fluid in the external water pipe 20 is in a flowing state. When the actual flow time measured by the timer 51 is greater than the preset flow time, it is determined that the water supply system 100 may have a leak. The controller 40 controls the normally open water valve 21 to close, stop the water supply, and prevent the external water source from flowing through the external water pipe 20, thereby effectively improving the leak-proof effect of the water supply system 100, preventing damage to homes or houses due to leakage, and improving the user experience.

[0242] In the first and second embodiments, the detection assembly 50 further includes a water pressure detector 52, which is electrically connected to the timer 51. The water pressure detector 52 is used to trigger the timer 51 to measure the actual flow time when it detects that the water pressure in the external water pipe 20 reaches a preset water pressure; wherein the preset water pressure is the water pressure in the external water pipe 20 when the fluid in the external water pipe 20 is in a flowing state. Figure 1 and Figure 2As shown, when the fluid in the external water pipe 20 is in a flowing state, the water pressure in the external water pipe 20 is P1; when the fluid in the external water pipe 20 is in a non-flowing state, the water pressure in the external water pipe 20 is P2, and P1 < P2; the preset water pressure is P1. The water pressure detector 52 is used to detect the water pressure in the external water pipe 20. When the water pressure detector 52 detects that the water pressure in the external water pipe 20 reaches P1, it means that the fluid in the external water pipe 20 is in a flowing state. The water pressure detector 52 triggers the timer 51 to start measuring the actual flowing duration. When the actual flowing duration measured by the timer 51 is greater than the preset flowing duration, and the water pressure in the external water pipe 20 is still P1 and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot enter the external water pipe 20, which not only plays a role in preventing water leakage, but also improves the stability of the system; or, the preset water pressure is P2. The water pressure detector 52 is used to detect the water pressure in the external water pipe 20. When the water pressure detector 52 detects that the water pressure in the external water pipe 20 is not P2, it means that the fluid in the external water pipe 20 is in a flowing state. The water pressure detector 52 triggers the timer 51 to start measuring the actual flowing duration. When the actual flowing duration measured by the timer 51 is greater than the preset flowing duration, and the water pressure in the external water pipe 20 is still not P2 and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot enter the external water pipe 20, which not only plays a role in preventing water leakage, but also improves the stability of the system.

[0243] Further, a detection box 22 is provided on the external water pipe 20. The detection box 22 is arranged between the normally open water valve 21 and the water-using device 30. An injection cavity 221 communicating with the external water pipe 20 is formed in the detection box 22. The water pressure detector 52 includes a pressure detection member 521 and a spring piece 522. The pressure detection member 521 is electrically connected to the timer 51. The spring piece 522 is suspended in the injection cavity 22, and the pressure detection member 521 is used to detect the pressure received by the spring piece 522. As Figure 1 and Figure 2 shown, a detection box 22 is arranged between the normally open water valve 21 and the water-using device 30. An injection cavity 221 is formed in the detection box 2, and the injection cavity 221 communicates with the external water pipe 20, so that the external water source can flow into the injection cavity 221 through the external water pipe 20. The spring piece 522 is suspended in the injection cavity 221. When the water pressure in the external water pipe 20 is P2, the spring piece 522 is deformed under pressure; when the water pressure in the external water pipe 20 is P1, the pressure received by the spring piece 522 decreases, and the deformation of the spring piece 522 decreases under the action of the restoring force.

[0244] Specifically, when the deformation of the spring 522 is large, that is, when the pressure detection component 521 detects that the pressure on the spring 522 is P2, it means that the water pressure in the external water pipe 20 is P2, and the fluid in the external water pipe 20 is in a non-flowing state; when the deformation of the spring 522 is small, that is, when the pressure detection component 521 detects that the pressure on the spring 522 is P1, it means that the water pressure in the external water pipe 20 is P1, and the fluid in the external water pipe 20 is in a flowing state, the pressure detection component 521 triggers the timer 51 to start measuring the actual flow time. When the actual flow time measured by the timer 51 is long, When the preset flow time is reached and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close; or, when the pressure detection component 521 detects that the pressure exerted on the spring 522 is not P2, it means that the water pressure in the external water pipe 20 is not P2, and the fluid in the external water pipe 20 is in a flowing state. The pressure detection component 521 triggers the timer 51 to start measuring the actual flow time. When the actual flow time measured by the timer 51 is greater than the preset flow time, and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close.

[0245] In a preferred embodiment, the pressure detection component 521 is a pressure strain gauge, which is stacked on the spring sheet 522 and electrically connected to the timer 51. The pressure strain gauge can be a pressure strain gauge in the prior art that can detect the pressure exerted on the spring sheet 522; or, the pressure detection component 521 is a pressure sensor, which is electrically connected to the timer 51. The pressure sensor can be a piezoresistive pressure sensor or other pressure sensor in the prior art that can detect the pressure exerted on the spring sheet 522.

[0246] In the third and fourth embodiments, the detection assembly 50 further includes a water flow detection member 53, which is electrically connected to the timer 51. The water flow detection member 53 is used to trigger the timer 51 to measure the actual flow time when the water flow rate in the external water pipe 20 reaches a preset water flow rate; wherein the preset water flow rate is the water flow rate in the external water pipe 20 when the fluid in the external water pipe 20 is in a flowing state. Figure 3 and Figure 4As shown, when the fluid in the external water pipe 20 is in a flowing state, the water flow rate in the external water pipe 20 is s1; when the fluid in the external water pipe 20 is in a non-flowing state, the water flow rate in the external water pipe 20 is s2, and s2 = 0 < s1; the preset water flow rate is s1, and the water flow detection component 53 is used to detect the water flow rate in the external water pipe 20. When the water flow detection component 53 detects that the water flow rate in the external water pipe 20 reaches s1, it indicates that the fluid in the external water pipe 20 is in a flowing state. The water flow detection component 53 triggers the timer 51 to start measuring the actual flowing duration. When the actual flowing duration measured by the timer 51 is greater than the preset flowing duration, and the water flow rate in the external water pipe 20 is still s1 and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot enter the external water pipe 20, which not only plays a role in preventing water leakage, but also improves the stability of the system. Or, the preset water flow rate is s2, the water flow detection component 53 is used to detect the water flow rate in the external water pipe 20. When the water flow detection component 53 detects that the water flow rate in the external water pipe 20 is not s2, it indicates that the fluid in the external water pipe 20 is in a flowing state. The water flow detection component 53 triggers the timer 51 to start measuring the actual flowing duration. When the actual flowing duration measured by the timer 51 is greater than the preset flowing duration, and the water flow rate in the external water pipe 20 is still not s2 and the fluid in the external water pipe 20 is still in a flowing state, the controller 40 controls the normally open water valve 21 to close, so that the external water source cannot enter the external water pipe 20, which not only plays a role in preventing water leakage, but also improves the stability of the system.

[0247] In a preferred embodiment, the water flow detection component 53 is a water flow velocity meter, and the water flow velocity meter is electrically connected to the timer 51. The water flow velocity meter can adopt a water flow velocity meter in the prior art that can detect the water flow rate. In other embodiments, the water flow detection component 53 can also be a water flow sensor in the prior art. The water flow sensor is used to detect the water flow rate in the external water pipe 20, and the water flow rate in the external water pipe 20 can be calculated through the detected water flow rate.

[0248] In a preferred embodiment, the normally open water valve 21 is a solenoid valve, and the solenoid valve is a normally open solenoid valve. The solenoid valve has the advantages of small volume, rapid response, and reliable operation, and the price of the solenoid valve is low, which not only saves economic costs, but also further increases the stability of the water supply system 100. The solenoid valve can adopt a solenoid valve in the prior art; or, the normally open water valve 21 is an electric valve, and the electric valve is a normally open electric valve. The opening and closing action speed of the electric valve can be adjusted, and the electric valve has a simple structure and is easy to maintain, which is not only convenient and fast to use, but also increases the stability of the water supply system 100. The electric valve can adopt an electric valve in the prior art.

[0249] In the first embodiment and the third embodiment, as Figure 1 and Figure 3As shown, a pressure reducing valve 23 is provided on the external water pipe 20. The pressure reducing valve 23 is provided between the water delivery device 10 and the normally open water valve 21. The external water source flows through the pressure reducing valve 23 through the water delivery device 10. The pressure reducing valve 23 is used to reduce the pressure of the water source flowing through. The pressure reducing valve 23 plays a role in regulating the water pressure, so that the pressure in the external water pipe 20 remains stable, further improving the stability of the system. The pressure reducing valve 23 can adopt the pressure reducing valve in the prior art.

[0250] In the second and fourth embodiments, as Figure 2 and Figure 4 As shown, a throttle valve 24 is provided on the external water pipe 20. The throttle valve 24 is provided between the water delivery device 10 and the normally open water valve 21. The external water source flows through the throttle valve 24 through the water delivery device 10. The throttle valve 24 is used to reduce the flow rate of the water source flowing through. The throttle valve 24 plays a role in controlling the water flow rate, so that the pressure in the external water pipe 20 remains stable, further improving the stability of the system. The throttle valve 24 can adopt the throttle valve in the prior art.

[0251] Optionally, in a second embodiment of the water supply system, the water supply system 100 includes a water delivery device 10, an external water pipe 20 and a water-using device 30. The water inlet end of the external water pipe 20 is connected to the water delivery end of the water delivery device 10, and the water outlet end of the external water pipe 20 is connected to the water-using device 30, so that the water delivery device 10 supplies water to the water-using device 30 through the external water pipe 20. The water-using device 30 is used to clean the cleaning robot. A controller 31 is provided on the water-using device 30, and a normally closed water valve 21 is provided on the external water pipe 20. The controller 31 is used to control the normally closed water valve 21 to be in an open state when the water-using device 30 uses water. It should be noted that the water supply system 100 can be used in a cleaning system, which includes a cleaning base station and a cleaning robot. The cleaning robot is provided with a mop, which needs to be cleaned with water after being used for a period of time. The cleaning base station has a mop cleaning device for cleaning the mop. The cleaning base station may be provided with a water tank or not. The water supply device 30 may be a cleaning base station, and the water supply device 10 may be a faucet that supplies water to the cleaning base station, and the faucet is a normally open faucet.

[0252] like Figures 5 to 10As shown, the water delivery device 10 is used to communicate with an external water source. The water delivery device 10 and the water-using device 30 are connected through an external water pipe 20, so that the external water source can flow into the external water pipe 20 through the water delivery device 10, and then flow into the water-using device 30 from the external water pipe 20. The normally closed water valve 21 is arranged on the external water pipe 20 near the water delivery device 10; when the cleaning robot needs to wash the mop at the cleaning base station, that is, when the water-using device 30 needs water, the controller 31 of the water-using device 30 controls the normally closed water valve 21 to open, so that the external water source can flow into the water-using device 30 through the water delivery device 10 and the external water pipe 20, and the cleaning robot can wash the mop at the cleaning base station. It can be understood that when the mop is washed or there is no need to wash the mop, that is, when there is no need to supply water to the water-using device 30, the normally closed water valve 21 is in a closed state, and the external water source cannot pass through the external water pipe 20, thereby preventing water leakage. The water supply system 100 has the advantages of good leak-proof performance, stability and reliability, and improves the user experience.

[0253] In this embodiment, the controller 31 is communicatively connected with the normally closed water valve 21, that is, the controller 31 on the water-using device 30 is communicatively connected with the normally closed water valve 21 on the external water pipe 20. When the water-using device 30 needs water, the controller 31 can control the normally closed water valve 21 to open; when there is no need to supply water to the water-using device 30, the normally closed water valve 21 is in a closed state, which effectively improves the leakage prevention effect of the water supply system 100, prevents damage to homes or houses due to leakage, and enhances the user experience.

[0254] In the first and second embodiments, as Figure 5 and Figure 6 As shown, the controller 31 is provided with a wireless signal transmission module 311, and the normally closed water valve 21 is provided with a wireless signal receiving module 211. The wireless signal transmission module 311 is used to transmit signals, and the wireless signal receiving module 211 is used to receive signals transmitted by the wireless signal transmission module 311, thereby establishing a wireless communication connection between the controller 31 and the normally closed water valve 21. Specifically, when the wireless signal transmission module 311 is not transmitting a signal, the normally closed water valve 21 is in a closed state, preventing water leakage in the water supply system 100. When the wireless signal transmission module 311 transmits a signal to the wireless signal receiving module 211, and the wireless signal receiving module 211 receives the signal, the normally closed water valve 21 is opened, and the water delivery device 10 supplies water to the water-using device 30 through the external water pipe 20, thereby achieving water supply to the water-using device 30. The signal transmission and reception between the wireless signal transmission module 311 and the wireless signal receiving module 211 can adopt existing technologies, such as using a wireless signal transmitter and a wireless signal receiver to transmit and receive wireless signals.

[0255] In the third and fourth embodiments, as Figure 7 and Figure 8As shown, the controller 31 and the normally closed water valve 21 are electrically connected via a wire 40, that is, one end of the wire 40 is electrically connected to the controller 31, and the other end of the wire 40 is electrically connected to the normally closed water valve 21, and the controller 31 and the normally closed water valve 21 are communicated via the wire 40; specifically, when there is no need to supply water to the water-using equipment 30, the normally closed water valve 21 is in a closed state to prevent the water supply system 100 from leaking; when the water-using equipment 30 needs water, the controller 31 controls the normally closed water valve 21 to open via the wire 40, and the water delivery equipment 10 supplies water to the water-using equipment 30 through the external water pipe 20 to realize water supply to the water-using equipment 30.

[0256] In a preferred embodiment, the normally closed water valve 21 is a solenoid valve, which is a normally closed solenoid valve. The solenoid valve has the advantages of small size, quick response and reliable operation, and the solenoid valve is inexpensive, which not only saves economic costs but also further increases the stability of the water supply system 100. The solenoid valve can adopt the solenoid valve in the prior art; or, the normally closed water valve 21 is an electric valve, which is a normally closed electric valve. The switching speed of the electric valve can be adjusted, and the electric valve has a simple structure and is easy to maintain. It is not only convenient and quick to use, but also increases the stability of the water supply system 100. The electric valve can adopt the electric valve in the prior art.

[0257] In the first and third embodiments, as Figure 5 and Figure 7 As shown, a pressure reducing valve 22 is provided on the external water pipe 20. The pressure reducing valve 22 is provided between the water delivery device 10 and the normally closed water valve 21. The external water source flows through the pressure reducing valve 22 through the water delivery device 10. The pressure reducing valve 22 is used to reduce the pressure of the water source flowing through. The pressure reducing valve 22 plays a role in regulating the water pressure, so that the pressure in the external water pipe 20 remains stable, further improving the stability of the system. The pressure reducing valve 22 can adopt a pressure reducing valve in the prior art; or, in the second embodiment and the fourth embodiment, as Figure 6 and Figure 8 As shown, a throttle valve 23 is provided on the external water pipe 20. The throttle valve 23 is provided between the water delivery device 10 and the normally closed water valve 21. The external water source flows through the throttle valve 23 through the water delivery device 10. The throttle valve 23 is used to reduce the flow rate of the water source flowing through. The throttle valve 23 plays a role in controlling the water flow rate, so that the pressure in the external water pipe 20 remains stable, further improving the stability of the system. The throttle valve 23 can adopt the throttle valve in the prior art.

[0258] In the fifth and sixth embodiments, the normally closed water valve 21 is a one-way valve, and a suction water pump 24 is further provided on the external water pipe 20. The normally closed water valve 21 is provided between the water delivery device 10 and the suction water pump 24. The controller 31 is electrically connected to the suction water pump 24. The pumping pressure of the suction water pump 24 is P1, and the opening pressure of the normally closed water valve 21 is P2, where P1 ≥ P2. Figure 9 and Figure 10 As shown, a suction water pump 24 and a normally-closed water valve 21 are provided on an external water pipe 20. The normally-closed water valve 21 is provided on the external water pipe 20 at a position close to the water delivery device 10, and the normally-closed water valve 21 is located between the water delivery device 10 and the suction water pump 24. A controller 31 on the water-using device 30 is electrically connected to the suction water pump 24, and the normally-closed water valve 21 is a one-way valve. The one-way valve is a normally-closed one-way valve. The opening pressure of the one-way valve is adjustable, and the one-way valve has the characteristic of one-way conduction. The one-way valve can adopt a one-way valve in the prior art.

[0259] When the water-using device 30 needs water, the controller 31 of the water-using device 30 controls the suction water pump 24 to start. The pumping pressure of the suction water pump 24 is P1, and the opening pressure of the one-way valve is P2. When P1≥P2, that is, when the pumping pressure of the suction water pump 24 is greater than or equal to the opening pressure of the one-way valve, the one-way valve opens, enabling the external water source to flow into the water-using device 30 through the water delivery device 10 and the external water pipe 20, thus realizing the water supply to the water-using device 30. It can be understood that when the mop cleaning is completed or when there is no need to clean the mop, that is, when there is no need to supply water to the water-using device 30, the suction water pump 24 is in a stopped state, and the one-way valve is in a closed state, preventing the external water source from passing through the external water pipe 20, playing a role in preventing water leakage. The water supply system 100 has the advantages of good leak prevention performance, stability and reliability, improving the user experience.

[0260] Furthermore, the external water pipe 20 includes an inlet section 25 and an outlet section 26. The water delivery device 10 is connected to the pumping end of the suction water pump 24 through the inlet section 25, and the outlet end of the suction water pump 24 is connected to the water-using device 30 through the outlet section 26. The normally-closed water valve 21 is provided on the inlet section 25. As Figure 9 and Figure 10 shown, the normally-closed water valve 21 is provided on the inlet section 25. The inlet section 25 and the outlet section 26 are connected through the suction water pump 24, and the inlet section 25 is connected to the water delivery device 10, and the outlet section 26 is connected to the water-using device 30, enabling the external water source to flow into the water-using device 30 in sequence through the water delivery device 10, the inlet section 25, the suction water pump 24 and the outlet section 26, realizing the water supply to the water-using device 30. The structural design is reasonable and the operation is convenient and fast.

[0261] In the fifth and sixth embodiments, the water delivery end pressure of the water delivery device 10 is P3, and P3<P2; specifically, the water inlet end of the external water pipe 20 is connected to the water delivery end of the water delivery device 10. When there is no need to supply water to the water-using device 30, the pressure at the water delivery end of the water delivery device 10 is P3, and P3<P2, that is, the pressure of the water output by the water delivery device 10 is less than the opening pressure of the one-way valve, and the one-way valve cannot be opened, that is, the external water source cannot pass through the one-way valve, playing a role in preventing water leakage.

[0262] [[ID=1 Figure 9 As shown, the pressure reducing valve 22 is provided on the water inlet section 25, and the pressure reducing valve 22 is provided between the water delivery device 10 and the normally closed water valve 21. The external water source flows through the pressure reducing valve 22 through the water delivery device 10. The pressure reducing valve 22 is used to reduce the pressure of the water source flowing through. The pressure reducing valve 22 plays the role of regulating the water pressure. The pressure reducing valve 22 adjusts the water pressure to P3, which not only ensures that the one-way valve cannot be opened, but also keeps the pressure in the external water pipe 20 stable, further improving the stability of the system. The pressure reducing valve 22 can adopt the pressure reducing valve in the prior art; or, in the sixth embodiment, as Figure 10 As shown, the throttle valve 23 is provided on the water inlet section 25, and the throttle valve 23 is provided between the water delivery device 10 and the normally closed water valve 21. The external water source flows through the throttle valve 23 through the water delivery device 10. The throttle valve 23 is used to reduce the flow rate of the water source flowing through. The throttle valve 23 plays a role in controlling the water flow rate, so that the water pressure is reduced to P3, which not only ensures that the one-way valve cannot be opened, but also keeps the pressure in the external water pipe 20 stable, further improving the stability of the system. The throttle valve 23 can adopt the throttle valve in the prior art.

[0263] Optionally, based on all the above embodiments, the external switch device may refer to Figure 11 and Figure 12 , the switching device comprises:

[0264] The switch valve 201 is used to open or close the water source;

[0265] The trigger component 202 is connected to the switch valve 201. The trigger component 202 is used to trigger the switch valve 201 to close the water source when a trigger condition is met.

[0266] The switch device 200 is installed at the junction of the water source faucet and the water pipe 20. The water pipe 20 connects the water source to the water tank of the cleaning robot. When the switch valve 201 closes the water source, water from the water source cannot flow into the water pipe 20, preventing water leakage caused by excessive water pressure in the water pipe 20.

[0267] Optionally, the trigger assembly 202 is used to trigger the on-off valve 201 to close, and the trigger assembly 202 is connected to the on-off valve 201. Connection methods include, but are not limited to, mechanical connection, electrical connection, and wireless connection. Different types of trigger assemblies 202 require different corresponding connection methods.

[0268] Optionally, the trigger component 202 can trigger the switch valve 201 to close by transmitting a trigger signal, or can drive the switch valve 201 to close by linkage with a connecting piece.

[0269] Optionally, the trigger component 202 includes but is not limited to the following structures:

[0270] (1) The trigger component 202 includes a water flow state detection component, which is used to detect the water flow state of the water pipe 20. When the water flow time of the water pipe 20 is greater than the preset water flow time, the trigger component 202 meets the trigger condition.

[0271] In this embodiment, the water flow state detection component is mainly used to detect whether the water pipe 20 is in a water flow state (a state in which water is flowing). If the water pipe 20 is detected to be in a water flow state, the water flow duration of the water pipe 20 is recorded. When the water flow duration is greater than a preset water flow duration, the trigger component 202 satisfies the trigger condition and then issues a trigger signal to trigger the switch valve 201 to shut off the water source.

[0272] It is understood that the preset water flow duration is determined according to the time required for the water tank of the cleaning robot to be filled with water. That is, when the water flow duration reaches the preset water flow duration, it is determined that the water tank is full of water. If water still flows at this time, it indicates that there is a possibility of leakage or seepage in the water pipe 20. Therefore, the water flow state detection component triggers the switch valve 201 to shut off the water source to prevent water leakage or seepage in the room.

[0273] (2) The trigger component 202 includes a water meter, which is used to detect the water flow of the water pipe 20; when the water meter detects that the water flow of the water pipe 20 reaches a preset threshold, the trigger component 202 meets the trigger condition.

[0274] In this embodiment, the water meter is used to detect the water flow in the water pipe 20. Optionally, the water meter includes a signal transmission module. When the water meter detects that the water flow has reached a preset threshold, the signal transmission module is triggered to send a trigger signal to the switch valve 201. Upon receiving the trigger signal, the switch valve 201 closes the water source. Alternatively, a connector is provided between the water meter and the switch valve 201. When the water meter detects that the water flow has reached a preset threshold, the connector applies a pulling or pushing force to the connector, which drives the switch valve 201 to close the water source. When the switch valve 201 is closed and the water meter detects no water flow, the current water flow is updated to 0 and recorded again next time.

[0275] It is understood that the preset threshold is determined based on the water capacity of the cleaning robot's water tank. That is, when the water flow rate reaches the preset threshold, the water tank is determined to be full. If water is still flowing at this point, it indicates that water pipe 20 may be leaking or seeping. Therefore, the water meter triggers valve 201 to shut off the water source to prevent water leakage or seepage in the room.

[0276] (3) Please refer to Figures 4 to 6 The trigger component 202 includes a water pressure detector 52, which is used to detect the water pressure in the water pipe 20. When it is detected that the water pressure in the water pipe 20 is different from the preset water pressure, the trigger component 202 meets the trigger condition.

[0277] The water pressure detector 52 is electrically or wirelessly connected to the switch valve 201. When the water pressure detector 52 detects that the water pressure in the water pipe 20 is different from the preset water pressure, it indicates that the water flow in the water pipe 20 is not the normal water flow under water use and there is a leak. Therefore, the trigger component 202 meets the trigger condition and triggers the switch valve 201 to shut off the water source.

[0278] It can be understood that the water pressure in the water pipe 20 when adding water to the cleaning robot is different from the water pressure in the water pipe 20 when the water pipe 20 leaks, and the water pressure during normal water addition is different from the water pressure in the water pipe 20 when the water pipe 20 leaks. Based on this, if the water pressure is detected to be different from the preset water pressure, it means that there is a leak in the water flow in the water pipe 20. At this time, closing the switch valve 201 can prevent water leakage.

[0279] (IV) Please refer to Figures 4 to 6 The trigger component 202 includes a water flow tachometer 53, which is used to detect the water flow velocity in the water pipe 20. When it is detected that the water flow velocity in the water pipe 20 is different from the preset water flow velocity, the trigger component 202 meets the trigger condition.

[0280] The water flow meter 53 is electrically or wirelessly connected to the switch valve 201. When the water flow meter 53 detects that the water flow speed in the water pipe 20 is different from the preset water flow speed, it indicates that the water flow in the water pipe 20 is not the normal water flow under normal use and there is a possibility of leakage. Therefore, the trigger component 202 meets the trigger condition and triggers the switch valve 201 to shut off the water source.

[0281] It can be understood that the water flow rate of the water pipe 20 when adding water to the cleaning robot is different from the water flow rate of the water pipe 20 when the water pipe 20 leaks, and the water flow rate during normal water addition is different from the water flow rate of the water pipe 20 when the water pipe 20 leaks. Based on this, if the water flow rate is detected to be different from the preset water flow rate, it means that there is a leak in the water flow in the water pipe 20. At this time, closing the switch valve 201 can prevent water leakage.

[0282] (V) Please refer to Figures 4 to 6The trigger component 202 includes a timer 51, which is connected to the switch valve 201. The switch valve 201 is a normally closed water valve. When the switch valve 201 is opened, the timer 51 is triggered to start timing. When the timing duration of the timer 51 reaches the preset water flow duration, the switch valve 201 is triggered to close.

[0283] Optionally, in some embodiments, the switch valve 201 and the timer 51 are mechanically connected, and the switch valve 201 is a normally closed water valve. When a water supply signal is received, the switch valve 201 opens, and the timer 51 is driven to start timing. When the timing of the timer 51 reaches the preset water flow time, the timing stops and the switch valve 201 is triggered to close the water source.

[0284] (VI) The trigger component 202 includes a receiving end 203. When the receiving end 203 receives a control signal, the trigger component 202 meets a trigger condition and triggers the switch valve 201 to close the water source.

[0285] Optionally, the receiving end 203 is used to receive a control signal sent by a controller. For example, when the switch device 200 is applied to the water pipe 20 of the cleaning robot, the receiving end 203 is used to receive a connection with the cleaning robot, and is used to receive a control signal sent by a base station, or a control signal sent by a detector of the base station, or a control signal triggered when a functional component of the base station is started. When the trigger component 202 receives the control signal, it triggers the switch valve 201 to close the water source. The switch valve 201 is triggered to close the water source based on a control signal, a detection signal, or a linkage signal of a functional component of the base station, and the control method of the switch valve 201 is diversified. Optionally, the control signal can be set to correspond to a signal triggered by a full water tank. In this way, when the water tank is full of water, the switch valve 201 is triggered to close, which can achieve an accurate water leakage prevention effect.

[0286] Alternatively, the receiving end 203 is used to receive a control signal from a detector, and the detector is used to detect parameters at both ends of the water pipe 20. If the difference between the parameters at both ends of the water pipe 20 does not fall within a preset threshold, it is configured as a water leak. At this time, the detector sends a control signal to the receiving end 203, and the trigger component 202 triggers the switch valve 201 to close the water source.

[0287] The two ends of the water pipe 20 include an end connected to the faucet switch and a water end connected to the water equipment. The parameters include at least one of water flow, water pressure, water flow speed and water flow time.

[0288] This embodiment controls the switch valve 201 through the detector and the receiving end 203, thereby achieving low-cost automatic control to prevent water leakage. Optionally, the trigger assembly 202 listed above can be used alone to trigger the switch valve 201, or at least two embodiments can be used in combination to trigger the switch valve 201.

[0289] In this embodiment, the switch device 200 is connected to the switch valve 201 by providing a trigger component 202. When the trigger component 202 meets a preset trigger condition, it triggers the switch valve 201 to close, thereby closing the water pipe 20 where the switch valve 201 is located. Because the switch device 200 has the function of automatically triggering the closure of the switch valve 201, combined with the application of a cleaning robot, the trigger condition of the trigger component 202 is configured according to the parameters of the water pipe 20 connected to the water source when the cleaning robot is leaking. Therefore, the leakage of the cleaning robot's water pipe 20 triggers the switch valve 201 to close the water source, thereby improving the leak prevention effect.

[0290] Optionally, the switch valve 201 is a normally open water valve 21 , or the switch valve 201 is a normally closed water valve 21 .

[0291] Optionally, if the switch valve 201 is a normally closed water valve 21, the trigger component 202 includes a receiving end 203 and a detection component, such as the detection component includes any one or more of a water flow state detector, a water pressure detector 52, a water flow tachometer 53, a water meter and a timer 51.

[0292] The receiving end 203 is used to receive a control signal, which is used to control the opening of the on-off valve 201 to open the water pipe. The detection component is used to detect the water pipe status of the water pipe and, based on the water pipe status, trigger the on-off valve 201 to shut off the water source. In other words, the normally closed water valve 21 is triggered to open by the control signal received by the receiving end 203, and is triggered to close by the water pipe status detected by the detection component.

[0293] Optionally, in some embodiments, when the trigger component 202 is a water flow state detection component, after the water flow state detection component detects the water flow state of the water pipe 20, it can identify whether the water flow time duration of the water pipe 20 in the water flow state is greater than the preset water flow time duration in the following manner.

[0294] In one embodiment, the switch device 200 further includes a timer 51, which is configured to send a trigger signal when the timer 51 reaches the preset water flow duration. Optionally, the timer 51 is connected to the water flow state detector and the switch valve 201 respectively. When the water flow state detector detects that the water pipe 20 is in a water flow state, the timer 51 is triggered to start timing. When the timer 51 reaches the preset water flow duration, the closing signal is sent to the switch valve 201 to trigger the switch valve 201 to shut off the water source.

[0295] In this embodiment, after the water flow status detection component detects the water flow signal, it triggers the timer 51 to start timing. When the timing duration of the timer 51 reaches the preset water flow duration, a closing signal is sent to the switch valve 201 to trigger the switch valve 201 to close the water source, thereby automatically triggering the switch valve 201 to close according to the parameters of the water pipe 20, thereby achieving a good leak prevention effect.

[0296] In another embodiment, the water flow state detection element and the switch valve 201 are connected via a control mainboard, that is, the control mainboard triggers the sending of the signal and the timing. If the switch device 200 further includes a control mainboard, the control mainboard is connected to the water flow state detection element and the switch valve 201 respectively. After the water flow state detection element detects the water flow signal in the water pipe 20, it sends the water flow signal to the control mainboard. After receiving the water flow signal, the control mainboard counts the time. When the counted time reaches a preset water flow time, it sends the closing signal to the switch valve 201 to trigger the switch valve 201 to shut off the water source.

[0297] Optionally, in some embodiments, the water flow state detection component includes a water pressure detector 52; the water pressure detector 52 is used to trigger the timer 51 or the control main board timing when it detects that the water pressure in the water pipe 20 reaches a preset water pressure; wherein, the preset water pressure is the water pressure in the water pipe 20 when the fluid in the water pipe 20 is in a flowing state.

[0298] Optionally, in other embodiments, the water flow state detection component includes a water flow tachometer 53, and the water flow tachometer 53 is used to trigger the timer 51 or the control main board timing when it detects that the water flow rate in the water pipe 20 reaches a preset water flow rate; wherein, the preset water flow rate is the water flow rate in the water pipe 20 when the fluid in the water pipe 20 is in a flowing state.

[0299] Because the water pressure or water flow in the water pipe 20 when the cleaning robot is supplying water normally is different from the water pressure or water flow in the water pipe 20 when it is leaking, a water pressure detector 52 or a water flow tachometer 53 is provided to determine when to trigger the timer 51 or the control main board to start timing, thereby realizing automatic timing and automatically triggering the switch valve 201 to shut off the water source.

[0300] It should be noted that when the cleaning robot is in a normal water supply state, the water pressure in the water pipe 20 reaches the preset water pressure, or the water flow rate reaches the preset water flow rate. Based on this, by calculating the time at the water flow rate or the preset water pressure, it is determined whether the water tank of the cleaning robot is full of water. After the water in the water tank is full, the switch valve 201 is closed, which can effectively prevent the water pipe 20 from leaking.

[0301] Optionally, in some embodiments, a detection box 22 is provided on the water pipe 20, and the detection box 22 is arranged between the switch valve 201 and the water source. A water injection chamber 221 connected to the water pipe 20 is formed in the detection box 22, and the water pressure detector 52 includes a pressure detection component 521 and a spring 522. The pressure detection component 521 is connected to the timer 51 or the control main board, and the spring 522 is suspended in the water injection chamber 221. The pressure detection component 521 is used to detect the pressure applied to the spring 522.

[0302] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
