[0033] See also Figure 1 As shown, Figure 1 A schematic diagram of the structure of a switchable liquid inlet system provided in an embodiment of the present invention, the system comprises a control unit, a switching component, at least two cleaning liquid storage components for storing cleaning liquid, and a detection component for real-time monitoring of the storage amount of cleaning liquid in at least two of the cleaning liquid storage components, the liquid inlet end of the switching component is connected to the pipeline of at least two of the cleaning liquid storage components, the liquid outlet end of the switching component is connected to the liquid outlet channel pipeline, the control unit is connected to the switching component and the detection component by signal, wherein:

[0034] The control unit is used to generate a switching signal and send it to the switching component when receiving the alarm signal sent by the detection component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0035] Alternatively, the control unit is used to determine whether the cleaning fluid storage amount in the cleaning fluid storage component is lower than the storage amount alarm threshold value based on the cleaning fluid storage amount signal when receiving the cleaning fluid storage amount signal sent by the detection component; if so, the control unit sends an alarm signal associated with the detection component, and generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning fluid storage component to another cleaning fluid storage component.

[0036] In this embodiment, the control unit can be any processor capable of data processing, such as a microprocessor, a programmable controller, etc.; the switching component can be any switching switch, switching valve, etc. capable of pipeline switching; the cleaning liquid storage component can be any container capable of storing cleaning liquid, such as a barrel, a bottle, etc.; the detection component can be any detection device capable of monitoring the storage amount of cleaning liquid in the cleaning liquid storage component, such as a weight sensor, a water level sensor, etc., and when it is detected that the storage amount of cleaning liquid in the cleaning liquid storage component is insufficient and is lower than the storage amount alarm threshold, an alarm signal is sent to the control unit. When the control unit is in the on state, if the alarm signal sent by the detection component is received, a switching signal is generated and sent to the switching component; after receiving the switching signal, the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component, so that the user does not need to plan the replacement time of the cleaning liquid storage component, and the liquid inlet system switches to another cleaning liquid storage component to ensure a continuous supply of cleaning liquid in the liquid inlet system, so that the liquid inlet system can continue to operate uninterruptedly.

[0037] For example, the current switching valve (i.e., the switching component) is connected to the cleaning liquid barrel T1 (i.e., the cleaning liquid storage component 1) and the cleaning liquid barrel T2 (i.e., the cleaning liquid storage component 2) storing the cleaning liquid, wherein the switching valve and the cleaning liquid barrel T1 are connected, and the switching valve and the cleaning liquid barrel T2 are disconnected. When the control unit receives the alarm signal sent by the detection component, the switching valve switches from the cleaning liquid barrel T1 to the cleaning liquid barrel T2.

[0038] In one embodiment, the control unit receives a cleaning fluid storage level signal sent by the detection component, and determines whether the cleaning fluid storage level in the cleaning fluid storage component is lower than the storage level alarm threshold based on the cleaning fluid storage level signal; if so, the control unit sends an alarm signal associated with the detection component, and generates a switching signal to send to the switching component, so that the switching component switches from the currently connected cleaning fluid storage component to another cleaning fluid storage component.

[0039] For example, the current switching valve (i.e., the switching component) is connected to the cleaning liquid barrel T1 (i.e., the cleaning liquid storage component 1) and the cleaning liquid barrel T2 (i.e., the cleaning liquid storage component 2) storing the cleaning liquid, wherein the switching valve and the cleaning liquid barrel T1 are connected, and the switching valve and the cleaning liquid barrel T2 are disconnected. The control unit receives the cleaning liquid storage amount signal sent by the detection component, and the control unit determines whether the cleaning liquid storage amount in the cleaning liquid barrel T1 is lower than the storage amount alarm threshold according to the cleaning liquid storage amount signal. If the cleaning liquid storage amount signal indicates that the cleaning liquid storage amount in the cleaning liquid barrel T1 is lower than the storage amount alarm threshold, the control unit generates a switching signal and sends it to the switching valve, so that the switching valve switches from the cleaning liquid barrel T1 to the cleaning liquid barrel T2.

[0040] In one embodiment, the switchable liquid inlet system provided by the embodiment of the present invention also includes a pipeline sensing component, which is arranged in the liquid outlet channel. The pipeline sensing component is connected to the control unit signal for real-time monitoring of the cleaning liquid outflow from the liquid outlet channel, and when the liquid outflow alarm threshold is reached, sending an alarm signal to the control unit; or, the pipeline sensing component is used to send a cleaning liquid outflow signal of the liquid outlet channel to the control unit, so that when the control unit receives the cleaning liquid outflow signal, it determines whether the cleaning liquid outflow from the liquid outlet channel is lower than the liquid outflow alarm threshold according to the cleaning liquid outflow signal, and if so, sends an alarm signal associated with the pipeline sensing component.

[0041] In this embodiment, in order to facilitate the detection of the outflow of cleaning liquid from the liquid outlet channel, a pipeline sensing component is provided in the liquid outlet channel, and the outflow of cleaning liquid from the liquid outlet channel is monitored by the pipeline sensing component. Among them, the pipeline sensing component can be a bubble sensing component or a water level sensing component, etc. The pipeline sensing component monitors the outflow of cleaning liquid from the liquid outlet channel in real time, and sends an alarm signal to the control unit when the outflow of cleaning liquid is lower than the outflow alarm threshold; or, the pipeline sensing component sends the outflow signal of cleaning liquid from the liquid outlet channel to the control unit; the control unit receives the outflow signal of cleaning liquid, and determines whether the outflow of cleaning liquid in the liquid outlet channel is lower than the outflow alarm threshold according to the outflow signal of cleaning liquid. When the outflow of cleaning liquid is lower than the outflow alarm threshold, the control unit sends an alarm signal associated with the pipeline sensing component.

[0042] For example, the pipeline sensing component is a bubble sensor, and when it is detected that the outflow of cleaning liquid in the liquid outlet channel is lower than the outflow alarm threshold, the bubble sensor sends an alarm signal to the control unit. Alternatively, the bubble sensor sends the outflow signal of cleaning liquid in the liquid outlet channel to the control unit, and the control unit receives the outflow signal of cleaning liquid and determines whether the outflow of cleaning liquid in the liquid outlet channel is lower than the outflow alarm threshold according to the outflow signal of cleaning liquid; when the outflow of cleaning liquid is lower than the outflow alarm threshold, the control unit sends an alarm signal associated with the bubble sensor.

[0043] In one embodiment, the switchable liquid inlet system provided by the embodiment of the present invention further includes a buffer component, which is connected to the liquid outlet channel pipeline and is used for buffering and storing the cleaning liquid output from the liquid outlet channel.

[0044] In this embodiment, in order to facilitate the user to store the cleaning liquid, a buffer component is provided in the liquid outlet channel for storing the cleaning liquid output from the liquid outlet channel, and the buffer component is connected to the liquid outlet channel pipeline to transport the cleaning liquid. The cleaning liquid flows from the liquid outlet pipe into the buffer component for storage. It should be noted that the buffer component can be any container, such as a barrel or a bottle. The cleaning liquid stored in the buffer component can be used by other systems or devices that require cleaning liquid.

[0045] In one embodiment, the detection component includes a first detection unit for monitoring the storage amount of the cleaning liquid in at least two of the cleaning liquid storage components and a second detection unit for monitoring the storage amount of the cleaning liquid in the buffer component, and the first detection unit and the second detection unit are both connected to the control unit signal.

[0046] In this embodiment, in order to better realize the switching, the detection component includes a first detection unit for monitoring the storage amount of the cleaning liquid in at least two cleaning liquid storage components, and a second detection unit for monitoring the storage amount of the cleaning liquid in the buffer component. Wherein, the first detection unit and the second detection unit are both connected to the control unit signal. The control unit switches the cleaning liquid storage component according to the alarm signal of the first detection unit; the control unit starts and closes the liquid inlet process according to the alarm signal of the second detection unit, thereby realizing the function of the switchable liquid inlet system. Wherein, the first detection unit can be the above-mentioned weight sensor, water level sensor, etc., and the second detection unit can be a float sensor, etc. Specifically, the float sensor has high and low positions, the circuit is disconnected when it is low, and the circuit is connected when it is high; when the float is low, it means that the storage amount of the cleaning liquid in the buffer component is insufficient, and at this time, a liquid inlet signal can be sent to the control unit, and when it is high, it means that the storage amount of the cleaning liquid in the buffer component is full, and at this time, an alarm signal can be sent to the control unit.

[0047] In one embodiment, a pump assembly is provided between the buffer assembly and the switching assembly, and the pump assembly is used to provide power for the liquid inlet system to transfer the cleaning liquid from the cleaning liquid storage assembly to the buffer assembly.

[0048] The present invention also provides a liquid filling method of a switchable liquid filling system as described in any one of the above, comprising: the control unit is used to generate a switching signal and send it to the switching component when receiving the alarm signal sent by the detection component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0049] Alternatively, the control unit is used to determine whether the cleaning fluid storage amount in the cleaning fluid storage component is lower than the storage amount alarm threshold value based on the cleaning fluid storage amount signal when receiving the cleaning fluid storage amount signal sent by the detection component; if so, the control unit sends an alarm signal associated with the detection component, and generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning fluid storage component to another cleaning fluid storage component.

[0050] like Figure 2 As shown, in the switchable liquid inlet method provided by the present invention, when the control unit receives the alarm signal sent by the detection component, it generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component, including:

[0051] Step S101, during the liquid inlet process, when the control unit receives the alarm signal sent by the detection component, it determines whether the alarm signal sent by the pipeline sensing component is received;

[0052] Step S102: if the alarm signal sent by the detection component and the alarm signal sent by the pipeline sensing component are received at the same time, a switching signal is generated and sent to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0053] Step S103: If the alarm signal sent by the pipeline sensor component is not received, a first fault signal is generated.

[0054] In this embodiment, during the liquid inlet process of the liquid inlet system, the control unit monitors the alarm signals of the detection component and the pipeline sensor component in real time. When receiving the alarm signal sent by the detection component, the control unit determines whether the alarm signal sent by the pipeline sensor component is received. If the alarm signals sent by the pipeline sensor component and the monitoring component are received at the same time, it proves that the cleaning liquid storage amount of the cleaning liquid storage component and the cleaning liquid flow rate in the liquid outlet channel pipeline have reached the alarm amount, and it is necessary to replace the current cleaning liquid storage component in time to restore the liquid outlet of the cleaning liquid. Therefore, the control unit generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component. If the alarm signal sent by the pipeline sensor component is not received, a first fault signal indicating that there is a damaged device component in the liquid inlet system is generated. Among them, the device component includes a detection component, a pipeline sensor component, a switching component or a pump liquid component.

[0055] like Figure 3As shown, in the switchable liquid inlet method provided by the present invention, when the control unit receives the alarm signal sent by the detection component, it generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component, including:

[0056] Step S201: During the liquid inlet process, when the control unit receives the alarm signal sent by the pipeline sensing component, it determines whether the alarm signal sent by the detection component is received;

[0057] Step S202: if the alarm signal sent by the detection component and the alarm signal sent by the pipeline sensing component are received at the same time, a switching signal is generated and sent to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0058] Step S203: If the alarm signal sent by the detection component is not received, a second fault signal is generated.

[0059] In this embodiment, during the liquid inlet process, when the control unit receives the alarm signal sent by the pipeline sensing component, it determines whether the alarm signal sent by the detection component is received. If the alarm signal sent by the detection component is not received, it indicates that there is sufficient cleaning liquid in the cleaning liquid storage component, but the cleaning liquid flow in the liquid outlet channel is insufficient and is lower than the liquid outlet alarm threshold, then a second fault signal is generated indicating that there is a pipeline fault in the liquid inlet system. Among them, pipeline faults may include loose pipeline joints, squeezed pipelines and other possible faults. The present application is divided into a first fault signal and a second fault signal according to the cause of the fault, which can help users conduct targeted inspections when encountering faults and reduce system maintenance pressure.

[0060] For example, the detection component is a weight sensor, and the pipeline sensing component is a bubble sensor. If the alarm signal of the weight sensor and the alarm signal of the bubble sensor are currently received, the switching component switches from the cleaning liquid barrel T1 currently connected to the cleaning liquid barrel T2; if the alarm signal of the weight sensor is currently received but the alarm signal of the bubble sensor is not received, a first fault signal is generated; if the alarm signal of the bubble sensor is currently received but the alarm signal of the weight sensor is not received, a second fault signal is generated.

[0061] like Figure 4 As shown, in the switchable liquid inlet method provided by the present invention, when the control unit receives the alarm signal sent by the detection component, it generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component, including:

[0062] Step S301: during the liquid inlet process, when the control unit issues an alarm signal associated with the detection component, determining whether to issue an alarm signal associated with the pipeline sensing component;

[0063] Step S302: if the alarm signals associated with the detection component and the pipeline sensing component are simultaneously issued, a switching signal is generated and sent to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0064] Step S303: If no alarm signal associated with the pipeline sensor assembly is issued, a first fault signal is generated.

[0065] In this embodiment, during the liquid inlet process, when the control unit sends out an alarm signal associated with the detection component, it is determined whether to send out an alarm signal associated with the pipeline sensing component; if the alarm signals associated with the detection component and the pipeline sensing component are sent out at the same time, it is proved that the cleaning liquid storage amount of the cleaning liquid storage component and the cleaning liquid flow rate in the liquid outlet channel pipeline have reached the alarm amount, and it is necessary to replace the current cleaning liquid storage component in time to restore the liquid outflow of the cleaning liquid, so the control unit generates a switching signal and sends it to the switching component to switch the switching component from the currently connected cleaning liquid storage component to another cleaning liquid storage component. If the alarm signal associated with the pipeline sensing component is not sent out, a first fault signal indicating that there is a damaged component in the liquid inlet system is generated. Among them, when the control unit sends out an alarm signal associated with the detection component, it indicates that the storage amount of the cleaning liquid in the cleaning liquid storage component is lower than the storage amount alarm threshold; when the control unit sends out an alarm signal associated with the pipeline sensing component, it indicates that the cleaning liquid outflow of the liquid outlet channel is lower than the liquid outflow alarm threshold.

[0066] like Figure 5 As shown, in the switchable liquid inlet method provided by the present invention, when the control unit receives the alarm signal sent by the detection component, it generates a switching signal and sends it to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component, including:

[0067] Step S401: during the liquid inlet process, when the control unit issues an alarm signal associated with the pipeline sensing component, determining whether to issue an alarm signal associated with the detection component;

[0068] Step S402: if the alarm signals associated with the detection component and the pipeline sensing component are simultaneously issued, a switching signal is generated and sent to the switching component, so that the switching component switches from the currently connected cleaning liquid storage component to another cleaning liquid storage component;

[0069] Step S403: If no alarm signal associated with the detection component is issued, a second fault signal is generated.

[0070] In this embodiment, during the liquid inlet process, when the control unit sends out an alarm signal associated with the pipeline sensing component, it determines whether to send out an alarm signal associated with the detection component; if the alarm signal associated with the detection component is not sent out, it indicates that there is sufficient cleaning liquid in the cleaning liquid storage component, but the cleaning liquid flow in the liquid outlet channel is insufficient and is lower than the liquid outlet alarm threshold, then a second fault signal is generated indicating that there is a pipeline fault in the liquid inlet system.

[0071] For example, the detection component is a weight sensor, and the pipeline sensing component is a bubble sensor. If the current control unit sends out an alarm signal associated with the weight sensor and also sends out an alarm signal associated with the bubble sensor, the switching component switches from the currently associated cleaning fluid barrel T1 to the cleaning fluid barrel T2; if the current alarm signal associated with the weight sensor is sent out, and the alarm signal associated with the bubble sensor is not sent out, a first fault signal is generated; if the current alarm signal associated with the bubble sensor is sent out, and the alarm signal associated with the weight sensor is not sent out, a second fault signal is generated.

[0072] like Figure 7 The structure diagram of an embodiment of the switchable liquid inlet system provided by the present invention is shown. C1 and C2 are two weighing sensors (equivalent to the first detection unit), which are respectively placed under the bases corresponding to the placement positions of the cleaning liquid barrel T1 and the cleaning liquid barrel T2. Q is a bubble sensor (equivalent to the pipeline sensing component), SV1 is a switching valve (equivalent to the switching component), P is a liquid inlet pump (equivalent to the pump liquid component), and F is a float sensor (equivalent to the second detection unit), which is placed in a buffer barrel H (equivalent to the buffer component). The weighing sensors C1 and C2 can monitor the changes in the storage volume of the cleaning liquid in the two cleaning liquid barrels in real time, and a storage volume alarm threshold can be set. When the storage volume of the cleaning liquid is lower than the storage volume alarm threshold, an alarm signal is issued. The bubble sensor Q is installed on the liquid outlet channel pipeline, and the bubbles in the pipeline are detected by infrared rays. The liquid outlet alarm threshold can be set, and an alarm signal is issued when the liquid outlet volume of the cleaning liquid is lower than the liquid outlet alarm threshold. The bubble sensor Q is calibrated to make the alarm level of the weighing sensors C1 and C2 basically consistent. The switching valve SV1 switches from the currently connected cleaning liquid barrel T1 to the cleaning liquid barrel when receiving the switching signal; the liquid inlet pump P is used to transfer the cleaning liquid to the buffer barrel H.

[0073] During the operation of the liquid inlet system, in the initial state, the switching valve SV1 is connected to the cleaning liquid barrel T1. As the water level in the buffer barrel H drops, the circuit is disconnected when the float sensor F is at a low position, and the system generates a liquid inlet signal to start the liquid inlet process. The liquid inlet pump P starts working, and the weighing sensor C1, the weighing sensor C2 and the bubble sensor Q start monitoring synchronously. The following situations exist: (1) When neither the weighing sensor C1 nor the bubble sensor Q alarms, the liquid inlet pump P continues to work until the float sensor F sends an alarm signal and stops inletting. The float sensor F alarm indicates that the cleaning liquid in the buffer barrel H has reached a high level and the cleaning liquid storage in the buffer barrel H is full, completing the liquid inlet process. (2) When both the bubble sensor Q and the weighing sensor C1 send out alarm signals, it indicates that the storage volume of the cleaning liquid in the cleaning liquid barrel T1 and the discharge volume of the cleaning liquid in the liquid discharge channel are insufficient. The control unit generates a switching signal and sends it to the switching valve SV1, so that the switching valve SV1 disconnects the cleaning liquid barrel T1 and connects the cleaning liquid barrel T2. When the bubble sensor Q and the weighing sensor C2 are normal, the liquid inlet pump continues to work until the float sensor F sends out an alarm signal and stops working to complete the liquid inlet. When at least one of the bubble sensor Q and the weighing sensor C2 still sends out an alarm signal, the control unit generates a first fault signal or a second fault signal. (3) When only one of the weighing sensor C1 or C2 and the bubble sensor Q sends out an alarm signal, the control unit generates a first fault signal or a second fault signal.

[0074] It should be noted that, according to the alarm relationship between the weighing sensors C1, C2 and the bubble sensor Q, the faults can be divided into the following types: (1) When the bubble sensor Q alarms and the weighing sensor C1 or C2 alarms, it is most likely that the cleaning liquid storage volume in the cleaning liquid barrel T1 and the cleaning liquid barrel T2 is insufficient, and the cleaning liquid in the liquid outlet pipeline has also been exhausted, and the cleaning liquid barrel needs to be replaced as soon as possible; (2) When the bubble sensor Q alarms and the weighing sensor C1 or C2 does not alarm, it may be that the cleaning liquid is sufficient and the pipeline is empty. The control unit generates a second fault signal, allowing the user to focus on whether the pipeline joints are loose or whether the pipeline is squeezed; (3) When the bubble sensor Q does not alarm, but the weighing sensor C1 or C2 alarms, the control unit generates a first fault signal, prompting the user that there is a fault in the weighing sensor C1 or C2, the bubble sensor Q, the liquid inlet valve or the liquid inlet pump, or there is a deviation in the calibration of the component.

[0075] like Figure 6 As shown, in one embodiment, the liquid feeding method further includes:

[0076] Step S501, using the detection component to monitor in real time the storage amount of the cleaning liquid in at least two of the cleaning liquid storage components;

[0077] Step S502, counting the remaining amount information according to the detected storage amount of the cleaning liquid to obtain statistical data;

[0078] Step S503, rendering the statistical data to obtain rendering data;

[0079] Step S504: calling a preset display framework to perform a UI display on the rendering data.

[0080] In this embodiment, in order to facilitate the user to more intuitively know the cleaning liquid situation in the liquid inlet system, the detection component is used to monitor the storage volume of the cleaning liquid in at least two cleaning liquid storage components in real time; then the remaining information is counted according to the cleaning liquid storage volume to obtain statistical data; the statistical data is rendered using rendering processing to obtain rendering data; and the preset display framework is called to display the rendering data in the UI.
