[0002] Modern cleaning equipment (such as floor scrubbers and robotic vacuum cleaners) requires liquids like water and detergents during operation, and therefore typically includes a liquid tank and piping for delivering these liquids. Normally, the sufficiency of the liquid in the cleaning equipment needs to be monitored, as this information is used to control other components within the equipment. However, the control requirements for different components may vary. Therefore, how to achieve precise control of different components within a cleaning equipment based on liquid level detection is a pressing technical problem that needs to be solved.

[0042] To enable those skilled in the art to better understand this application, firstly, in conjunction with Figure 1 and Figure 2 This application provides a brief description of the cleaning equipment and its system architecture.

[0043] See Figure 1 The diagram shows the system architecture of the cleaning equipment in an embodiment of this application.

[0044] like Figure 1 The illustration shows a cleaning equipment system architecture in one embodiment, which includes a liquid tank 101, a liquid detection device 102 (e.g., a flow meter, a level gauge), a first three-way valve 103, a detergent tank 104, a detergent pump 105, a second three-way valve 106, a heating device liquid pump 107, a pressure relief valve 108, a liquid heating device 109 (e.g., a boiler), a filter screen 110, a first reversing valve 111, a steam port 112, a liquid pump 113, a second reversing valve 114, a third three-way valve 115, and cleaning components 116 (e.g., a cleaning roller brush, a mop).

[0045] The liquid tank 101 is used to store liquid, which can be clean water or other liquids that can clean the floor or cleaning parts; this application does not specifically limit this. The liquid detection device 102 is used to detect whether there is liquid in the liquid pipeline. The heating device liquid pump 107 is used to pump a set flow rate of liquid into the liquid heating device 109, so that the liquid heating device 109 heats the liquid to generate steam, which flows through the first reversing valve 111 to the steam nozzle 112, and finally sprays the steam onto the ground.

[0046] In this embodiment, the first reversing valve 111 and the second reversing valve 114 are used to switch the flow path of the liquid in the liquid pipeline to switch between different cleaning modes of the cleaning equipment. In the cleaning equipment of this embodiment, the liquid flow path may include flow path A, flow path B, and flow path C, which are used by the cleaning equipment to perform cleaning tasks in cold liquid mode, hot liquid mode, and steam mode, respectively. In addition, the cleaning equipment also includes flow path D for delivering cleaning agent to the entire liquid pipeline.

[0047] Specifically, in the cold liquid mode, the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the second three-way valve 106, the liquid pump 113, the second reversing valve 114, the third three-way valve 115, and the cleaning component 116. Since the liquid is not heated by the liquid heating device 109, the liquid flowing to the cleaning component 116 is in a low-temperature liquid state.

[0048] In the hot liquid mode, the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the second three-way valve 106, the liquid pump 113, the second reversing valve 114, the pressure relief valve 108, the liquid heating device 109, the filter screen 110, the first reversing valve 111, the third three-way valve 115, and the cleaning component 116. Since the liquid is heated by the liquid heating device 109, the liquid flowing to the cleaning component 116 is in a high-temperature liquid state.

[0049] In steam mode, the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the heating device liquid pump 107, the pressure relief valve 108, the liquid heating device 109, the filter screen 110, the first reversing valve 111, and the steam port 112. Since the liquid is heated by the heating device liquid pump 107 and the liquid heating device 109, the liquid flowing to the steam port 112 is in a high-temperature gaseous state.

[0050] See Figure 2 The diagram illustrates the liquid detection device of the cleaning equipment in this application embodiment detecting the liquid state.

[0051] like Figure 2 As shown, the cleaning equipment includes a liquid tank 101 and a liquid pipeline 117 for conveying liquid. To ensure a continuous liquid supply, it is necessary to accurately monitor whether the liquid level in the liquid tank 101 is sufficient, so that the user can be promptly notified to replenish the liquid if it is low. Therefore, a liquid detection device 102 is installed in the liquid pipeline 117 to determine whether the liquid level in the liquid tank 101 is sufficient by detecting the presence of liquid in the liquid pipeline 117, and this information serves as the basis for controlling the indicator and liquid heating devices within the cleaning equipment.

[0052] In this application, the cleaning equipment may include a controller and a liquid detection device (e.g., Figure 1 and Figure 2 The liquid detection device 102 shown), the indicator device, and the liquid heating device (e.g., liquid heating device) Figure 1 The liquid heating device 109 shown is an example. The cleaning equipment can be a floor scrubber or a robotic vacuum cleaner, and this application does not specifically limit it. Taking a floor scrubber as an example, during the operation of the floor scrubber (such as performing surface cleaning), the controller can obtain information on whether there is liquid in the liquid pipeline collected by the liquid detection device, and control the opening or closing of the prompting device and the opening or closing of the liquid heating device based on the information.

[0053] In some embodiments, the notification device may be a display screen. When the controller determines that the liquid level in the tank is low, it can turn on the display screen to show a text message such as "Low liquid, please replenish as soon as possible!" When the controller determines that the liquid level in the tank is sufficient, it can turn off the display screen.

[0054] In some embodiments, the prompting device may also be a speaker. When the controller determines that the liquid level in the tank is low, it can activate the speaker to broadcast a voice prompt message such as "Low liquid level, please refill as soon as possible!" When the controller determines that the liquid level in the tank is sufficient, it can deactivate the speaker.

[0055] In some other embodiments, the notification device can also be a signal transmitting device. When it is determined that the liquid in the tank is low, the controller can activate the signal transmitting device to send a low liquid notification message to a remote terminal (such as a mobile phone), allowing the user to receive the notification message via the remote terminal. When it is determined that the liquid in the tank is sufficient, the controller can deactivate the signal transmitting device.

[0056] In some embodiments, the liquid heating device can be a boiler. When it is determined that the liquid in the liquid tank is insufficient, the controller can shut down the boiler to stop heating the liquid and prevent the boiler from burning dry. When it is determined that the liquid in the liquid tank is sufficient, the controller can turn the boiler on.

[0057] Next, the implementation details of the technical solutions in the embodiments of this application will be described in detail.

[0058] Before proceeding, it should be noted that, in order to enable those skilled in the art to better understand this application, this application will provide some embodiments that include control parameters. However, the specific values ​​of the control parameters in the embodiments are merely exemplary. In practical applications, the control parameters in the embodiments may be other values ​​depending on the actual situation.

[0059] Reference Figure 3 The flowchart of the cleaning equipment control method in the embodiment of this application is shown, wherein the liquid pipeline of the cleaning equipment is provided with a detection device.

[0060] This cleaning equipment control method can be executed by a device with computing processing capabilities, see reference. Figure 3 As shown, the cleaning equipment control method includes at least steps 310 to 330:

[0061] Step 310: Obtain the liquid signal collected by the detection device. The liquid signal is used to characterize whether there is liquid at the location of the detection device.

[0062] Step 320: Analyze the liquid signal based on the first mode, and control the opening or closing of the prompting device based on the obtained first analysis result. The prompting device is configured to issue a prompt for liquid replenishment.

[0063] Step 330: Analyze the liquid signal based on the second mode, and control the liquid heating device to turn on or off based on the obtained second analysis result.

[0064] In this application, the detection device may be the aforementioned liquid detection device 102. The detection device can collect liquid signals in the liquid pipeline at a set frequency.

[0065] Specifically, collecting liquid signals at a set frequency can mean that the detection device periodically detects the state of the liquid at predetermined time intervals, such as collecting a liquid signal every 50 milliseconds or every 60 milliseconds. In this application, the set frequency can be set according to actual conditions, and this application does not impose specific limitations on it.

[0066] It should be noted that the detection device can also collect the liquid signal in other ways. For example, the liquid signal can be collected alternately at different time intervals.

[0067] In this application, the detection device can measure parameters such as liquid level, pressure, or flow rate, enabling the cleaning equipment to determine whether liquid exists in the liquid pipeline at the detection device location based on these parameters. For example, the detection device can be a level gauge, which can detect the liquid height in the liquid pipeline. When the liquid height is lower than a set liquid height, it can be determined that there is no liquid in the liquid pipeline at the level gauge location, thereby triggering a first signal; conversely, when the liquid height is higher than or equal to the set liquid height, it can be determined that there is liquid in the liquid pipeline at the level gauge location, thereby triggering a second signal. It is understood that the second signal can reflect the presence of liquid in the liquid pipeline at the detection device location.

[0068] In this application, after acquiring a liquid signal characterizing the presence of liquid at the location of the detection device, the activation or deactivation of the prompting device is controlled by a first analysis result obtained from analyzing the liquid signal based on a first mode, and the activation or deactivation of the liquid heating device is controlled by a second analysis result obtained from analyzing the liquid signal based on a second mode. This configuration allows for the use of different control modes for different devices, thereby meeting the sensitivity requirements of different devices for liquid detection and achieving precise control of different devices.

[0069] Specifically, on the one hand, the first analysis result, based on the analysis of the liquid signal in the first mode, controls the activation or deactivation of the prompting device. This allows it to prompt the user to replenish the liquid at a relatively accurate time, ensuring that the cleaning equipment always has sufficient liquid (such as clean water) during operation to maintain its optimal working condition. On the other hand, the second analysis result, based on the analysis of the liquid signal in the second mode, controls the activation or deactivation of the liquid heating device. This determines when to operate the liquid heating device and when to deactivate it. For example, it can operate when the cleaning equipment has sufficient liquid and deactivate it when the cleaning equipment has insufficient liquid. This effectively prevents the liquid heating device from dry-burning, improves the safety and lifespan of the cleaning equipment, optimizes energy utilization, and reduces unnecessary power consumption. It is evident that by analyzing the liquid signals in the liquid pipeline using different parallel modes, and controlling the activation and deactivation of the indicator device and the liquid heating device in the cleaning equipment based on the different analysis results, the different sensitivity requirements of the indicator device and the liquid heating device for liquid signal analysis can be met. This reduces false alarms from the indicator device while also lowering the risk of dry burning of the liquid heating device. Therefore, the technical solution proposed in this application can achieve precise control of different devices in the cleaning equipment.

[0070] The first mode is different from the second mode. Therefore, for the same liquid signal collected by the detection device, the control results obtained using the first mode and the second mode may be different. For example, when the first mode is used to control the indicator device to turn on, the liquid heating device controlled based on the second mode may be on or off. When the first mode is used to control the indicator device to turn off, the liquid heating device controlled based on the second mode may be on or off. Similarly, when the second mode is used to control the liquid heating device to turn off, the indicator device controlled based on the first mode may be on or off. When the second mode is used to control the liquid heating device to turn on, the indicator device controlled based on the first mode may be on or off. That is, the control results of the indicator device and the liquid heating device are independent. Moreover, the control of the indicator device and the liquid heating device may be asynchronous. For example, the control result of the indicator device may precede the control result of the liquid heating device, or vice versa. Next, this application will specifically describe the first mode.

[0071] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may include the following step 321:

[0072] Step 321: If the number of times the liquid signal is the first signal continuously reaches a first set number, then the cleaning equipment is determined to be in a first state. The first signal indicates that there is no liquid at the location of the detection device. The first state includes insufficient liquid in the cleaning equipment.

[0073] In this application, if the number of times the liquid signal continuously corresponds to the first signal reaches a first preset number, the cleaning device is determined to enter a first state (i.e., the cleaning device is determined to be in a state of insufficient liquid, also known as a water shortage state). For example, if the number of times the liquid signal continuously corresponds to the first signal reaches 60 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the first signal is 3 seconds), the cleaning device is determined to enter the first state. Alternatively, if the number of times the liquid signal continuously corresponds to the first signal reaches 80 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the first signal is 4 seconds), the cleaning device is determined to enter the first state. In this application, the first preset number can be set according to actual conditions, and this application does not specifically limit it. In some embodiments, the first preset number is related to the liquid signal acquisition frequency and the operating power of the liquid pump. For example, the higher the liquid signal acquisition frequency, the more preset numbers are required; conversely, the greater the operating power of the liquid pump, the fewer preset numbers are required, and so on.

[0074] The execution device of the cleaning equipment control method may store a character for recording the state of the cleaning equipment corresponding to the prompting device. For ease of description, we define this character as the first character. In the scenario corresponding to the prompting device, when the cleaning equipment enters the first state, the value of the first character can be the character value corresponding to the first state.

[0075] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include the following step 322:

[0076] Step 322: If the duration of the cleaning device in the first state is greater than or equal to the first set duration, then control the prompting device to be in the on state.

[0077] In this application, after determining that the cleaning equipment has entered a first state, the duration of the cleaning equipment in the first state can be recorded, thereby controlling the activation or deactivation of the prompting device based on the duration. It is understood that if the duration is long, it can be largely determined that the liquid in the cleaning equipment is insufficient, thus allowing the prompting device to be activated to send a liquid replenishment prompt to the user. Therefore, a liquid replenishment prompt will only be sent to the user when the liquid in the cleaning equipment is truly insufficient, avoiding the situation where the liquid level in the tank is low but the liquid level is incorrectly determined to be sufficient, and also avoiding the situation where the liquid level in the tank is sufficient but the user is incorrectly prompted that the liquid level is low.

[0078] Conversely, if the duration of the cleaning equipment in the first state is short, since it takes a certain amount of time for the liquid in the liquid tank to be transported to the location of the detection device in the liquid pipeline, it cannot be absolutely determined that the liquid in the liquid tank of the cleaning equipment is insufficient. In this case, a liquid replenishment prompt message cannot be issued to the user, and the liquid signal needs to be analyzed further for judgment.

[0079] Based on this, in this application, if the duration of the cleaning equipment in the first state is greater than or equal to a first set duration, it indicates that there is no liquid in the liquid pipeline of the cleaning equipment during that period. Therefore, it can be determined to a large extent that the cleaning equipment is indeed in a state of insufficient liquid. In this case, the prompting device can be controlled to be in the on state to send a liquid replenishment prompt to the user so that the user can replenish the liquid in time. This ensures that when the cleaning equipment is indeed in a state of insufficient liquid, the user can receive a notification to replenish the liquid in a timely manner, thereby avoiding the cleaning effect of the cleaning equipment or causing abnormal operation of the equipment due to insufficient liquid. In this way, this time-based judgment method can reduce the possibility of false alarms for liquid replenishment prompts, avoid frequent prompts to the user during short-term state fluctuations, thereby reducing false alarms and unnecessary prompts, enhancing the credibility of the prompt information, improving the accuracy and reliability of controlling the cleaning equipment, and thus improving the user experience.

[0080] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include the following step 323:

[0081] Step 323: If the number of times the liquid signal is the second signal continuously reaches a second set number, then it is determined that the cleaning equipment is in the second state. The second signal indicates that there is liquid at the location of the detection device. The second state includes sufficient liquid in the cleaning equipment.

[0082] In this application, if the number of times the liquid signal continuously corresponds to the second signal reaches a second preset number, the cleaning device is determined to enter a second state (i.e., the cleaning device is determined to have sufficient liquid, also known as a water-containing state). For example, if the number of times the liquid signal continuously corresponds to the second signal reaches 60 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the second signal is 3 seconds), the cleaning device is determined to enter the second state. Alternatively, if the number of times the liquid signal continuously corresponds to the second signal reaches 80 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the second signal is 4 seconds), the cleaning device is determined to enter the second state. In this application, the second preset number can be set according to actual conditions, and this application does not specifically limit it. In some embodiments, the second preset number is related to the liquid signal acquisition frequency and the operating power of the liquid pump. For example, the higher the liquid signal acquisition frequency, the more preset numbers are required; conversely, the greater the operating power of the liquid pump, the fewer preset numbers are required, and so on.

[0083] The second set number of attempts can be the same as or different from the first set number of attempts. The first set number of attempts can be greater than or less than the second set number of attempts.

[0084] In the scenario corresponding to the prompting device, when the cleaning equipment enters the second state, the value of the first character can be the character value corresponding to the second state.

[0085] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include the following step 324:

[0086] Step 324: If the cleaning equipment is in the second state, then control the liquid indicator device to be in the off state.

[0087] In this application, the cleaning equipment will only enter the second state indicating sufficient liquid when it is determined that the liquid in the cleaning equipment is truly sufficient. At this time, the liquid indicator device is controlled to be in the off state. This can avoid the situation where the liquid tank is full and the user is incorrectly prompted that the liquid is insufficient, and also avoid the situation where the liquid tank is insufficient and the liquid is incorrectly judged to be sufficient. This can improve the credibility of the prompt information and enhance the accuracy and reliability of controlling the cleaning equipment.

[0088] In this application, step 325 may also be performed:

[0089] Step 325: In response to the activation of the cleaning equipment, determine that the cleaning equipment has entered the second state (i.e., the cleaning equipment is determined to be in a state of sufficient liquid under the liquid replenishment prompt task).

[0090] In this application, when the cleaning equipment starts up, determining that it has entered a second state indicating sufficient liquid has the advantage of preventing false prompts to the user about insufficient liquid when the liquid tank is full. This is because in some special cases, such as when using the cleaning equipment for the first time, the user may fill the liquid tank completely, but the liquid lines may be empty. In such cases, if the cleaning equipment is determined to be in the first state indicating insufficient liquid upon startup, it may incorrectly issue a liquid replenishment prompt to the user, leading to false prompts and affecting the user experience. This approach reduces false alarms and unnecessary prompts, enhances the credibility of prompts, improves the reliability of controlling the cleaning equipment, thereby reducing the user's maintenance burden and improving the user experience.

[0091] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include the following step 326:

[0092] Step 326: If the number of times the cleaning device continuously acquires the second signal in the first state does not reach the second set number, then it is determined that the cleaning device remains in the first state.

[0093] In this application, the cleaning device can track the number of consecutive times it receives a second signal in a first state. If the number of consecutive times does not reach a pre-set first number, the cleaning device determines that it is still in the first state. In this way, misjudgments caused by occasional factors or brief fluctuations can be avoided (i.e., avoiding misjudgments that the cleaning device has entered the second state due to the acquisition of scattered second signals in the first state). This ensures that the cleaning device has a certain anti-interference capability in judging its liquid status, and guarantees that the cleaning device will not arbitrarily determine that it has entered the second state indicating sufficient liquid when the liquid is insufficient. Furthermore, by reducing the sensitivity of monitoring the liquid status under the liquid replenishment prompt task, the influence of the detection value fluctuation caused by the mixing of liquid and air in the liquid pipeline on the detection results can be eliminated, improving the reliability of the cleaning device's liquid status monitoring and the reliability of the liquid replenishment prompt information, thereby enhancing the user's confidence in the operation of the cleaning device.

[0094] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include the following step 327:

[0095] Step 327: If the number of times the cleaning device continuously acquires the first signal in the second state does not reach the first set number, then it is determined that the cleaning device remains in the second state.

[0096] In this application, the cleaning device can track the number of consecutive times it receives a first signal in a second state. If the number of consecutive times does not reach a preset first number, the cleaning device determines that it is still in the second state. In this way, misjudgments caused by occasional factors or brief fluctuations can be avoided (i.e., avoiding misjudgments that the cleaning device has entered the first state due to the acquisition of scattered first signals in the second state). This ensures that the cleaning device has a certain anti-interference capability in judging its liquid status, and guarantees that the cleaning device will not erroneously issue liquid replenishment prompts to the user when the liquid is sufficient. Furthermore, by reducing the sensitivity of monitoring the liquid status under liquid replenishment prompt tasks, the influence of detection value fluctuations caused by the mixing of liquid and air in the liquid pipeline on the detection results can be eliminated, improving the reliability of the cleaning device's monitoring of its liquid status and the reliability of the liquid replenishment prompts, thereby enhancing the user's trust in the operating status of the cleaning device.

[0097] In this application, the first set duration, as described above, can be set according to the actual situation, and this application will explain this in detail below.

[0098] In this application, the step of controlling the prompting device to be in the on state if the duration of the cleaning device in the first state is greater than or equal to the first set duration may include the following steps 3281 to 3282:

[0099] Step 3281: When the cleaning equipment enters the first state, the operating power of the liquid pump in the liquid pipeline is increased to the set operating power, and the operating time of the liquid pump at the set operating power is controlled within the first set time.

[0100] Step 3282: If the cleaning equipment is still in the first state after the liquid pump has finished running at the set operating power, then the prompting device is controlled to be turned on.

[0101] In this embodiment, if the cleaning equipment enters the first state, it means that there may be insufficient liquid in the liquid pipeline. In this case, in order to quickly determine whether there is actually enough liquid in the liquid tank of the cleaning equipment, the operating power of the liquid pump can be increased to a set operating power (e.g., 10V, which can be set according to actual conditions, and this application does not specifically limit it) to improve the liquid delivery efficiency and flow rate, so as to ensure that the liquid can be delivered to the required parts quickly and sufficiently. In this way, on the one hand, the cleaning equipment can quickly detect whether it is actually in a state of insufficient liquid. If there is enough liquid in the liquid tank of the cleaning equipment, the cleaning equipment can be quickly determined to enter the second state (i.e., the state of sufficient liquid); if there is insufficient liquid in the liquid tank of the cleaning equipment, it can also be determined in a short time, thereby enhancing the timeliness of issuing liquid replenishment reminders to users. On the other hand, if there is enough liquid in the liquid tank of the cleaning equipment, the liquid pipeline can also be filled with liquid quickly, thereby resuming the cleaning operation of the cleaning equipment in a timely manner, ultimately improving user satisfaction and the reliability of cleaning equipment control.

[0102] It should be noted that the operating power setting should not be too high, so as to avoid the liquid pump operating at too high a power and generating excessive noise, which would affect the user experience.

[0103] Furthermore, in this application, the step of controlling the prompting device to be in the on state if the duration of the cleaning device in the first state is greater than or equal to the first set duration may include the following step 3283:

[0104] Step 3283: If the cleaning equipment is determined to be not in the first state during the period when the liquid pump is operating at the set operating power, the operating power of the liquid pump is reduced to the initial operating power.

[0105] In this application, after increasing the operating power of the liquid pump to the set operating power, if the cleaning equipment is determined to be not in the first state, i.e., in the second state with sufficient liquid, the operating power of the liquid pump can be reduced back to the initial operating power. This avoids unnecessary energy consumption, effectively reduces wear on the cleaning equipment, and extends the service life of the liquid pump. Furthermore, restoring to the initial operating power reduces noise and vibration, improving the operational stability of the cleaning equipment and the user experience. In this way, the cleaning equipment can meet liquid requirements while achieving more efficient energy management and longer maintenance cycles, ensuring the reliability and economy of the cleaning equipment under various operating conditions.

[0106] In this embodiment, by increasing the operating power of the liquid pump in the liquid pipeline, the liquid delivery efficiency in the liquid tank is improved, and the first set time can be set to a shorter duration, such as 10 seconds, 8 seconds, or 11 seconds. Specifically, this application does not impose further limitations on this.

[0107] In this application, the operating power of the liquid pump in the liquid pipeline may not be adjusted. In this case, since the liquid delivery efficiency in the liquid tank is not improved, the first set time can be set to a relatively large value, such as 30 seconds, 28 seconds, or 32 seconds. Specifically, this application does not impose further limitations on this.

[0108] In some embodiments, controlling the prompting device to be in the on state if the duration of the cleaning device in the first state is greater than or equal to a first preset duration may include the following step 3221:

[0109] Step 3221: If the reaction time of the cleaning device is less than or equal to the second set time, and the duration of the cleaning device in the first state is greater than or equal to the first set time, then the prompting device is controlled to be turned on, and the cleaning device is controlled to stop running. The reaction time includes the time between the time when the cleaning device is determined to enter the first state and the start time of the cleaning device.

[0110] In other embodiments, controlling the prompting device to be in the on state if the duration of the cleaning device in the first state is greater than or equal to a first preset duration may include the following steps 3222 to 3223:

[0111] Step 3222: If the reaction time of the cleaning device is greater than the second set time, and the duration of the cleaning device in the first state is greater than or equal to the first set time, then the prompting device is controlled to be in the on state.

[0112] Step 3223: If the cleaning equipment is in the first state for a duration greater than or equal to a third set duration after the prompting device is in the on state, then control the cleaning equipment to stop operating.

[0113] To enable those skilled in the art to better understand this application, the following is combined with Figure 4 The following is an illustration using a specific example.

[0114] Reference Figure 4 The diagram shows a control flowchart of the cleaning equipment in an embodiment of this application.

[0115] In one embodiment of this application, the sampling frequency of the liquid signal in the liquid pipeline can be set to 50 milliseconds / time, that is, it takes 3 seconds to continuously sample 60 liquid signals. In this embodiment, the second set duration can be 5 seconds (in other embodiments, the second duration can be adjusted according to the actual situation, such as 6 seconds or 7 seconds, and this application does not impose any restrictions on it).

[0116] The second set duration is related to the size of the cleaning equipment, the pump's operating power, and the length of the pipeline. When the time between the cleaning equipment entering a water-deficient state (first state) and the equipment's startup time falls within the second set duration, this time is insufficient to wet the cleaning components. Therefore, the second set duration can be determined based on the shortest time required to wet the cleaning components after the cleaning equipment starts. The second set duration may vary depending on the type of cleaning equipment.

[0117] The third set duration can be determined based on how long the cleaning components of the cleaning equipment can remain wet after they have been wetted. The third set duration may also vary depending on the material and size of the cleaning components.

[0118] like Figure 4 As shown, after the cleaning equipment is started (the start time of the cleaning equipment is recorded as the first second), it can be determined that the cleaning equipment has entered a second state indicating sufficient liquid. Further, if the cleaning equipment is again determined to enter a first state indicating insufficient liquid after entering the second state, the operating power of the liquid pump can be increased to the set operating power. If the cleaning equipment is determined to enter the second state within 10 seconds (i.e., the first set duration) (i.e., the duration of the cleaning equipment in the first state does not meet the first set duration), it indicates that the liquid in the tank is sufficient, and there is no need to stop the cleaning equipment. If the cleaning equipment remains in the first state after 10 seconds (i.e., the duration of the cleaning equipment in the first state meets the first set duration), it indicates that the liquid in the tank is insufficient, and the prompting device needs to be turned on to send a liquid replenishment prompt to the user.

[0119] Further, in the above embodiments, in one case, if it is determined that the cleaning device enters a first state reflecting insufficient liquid at the 5th second, then the condition of step 3221 above is satisfied, that is, the reaction time of the cleaning device (i.e., the time between the time when the cleaning device is determined to enter the first state (the 5th second) and the start time of the cleaning device (the 1st second) is 4 seconds) is less than or equal to the second set time (5 seconds). In this case, it means that the cleaning device continuously collects the first signal 60 times within the time from the 2nd second to the 4th second, thus indicating that there is liquid in the liquid pipeline only in the 1st second. That is, at the 5th second, only the small amount of liquid that existed in the liquid pipeline in the 1st second is delivered to the cleaning component of the cleaning device, and the liquid that existed only in the 1st second is insufficient to wet the cleaning component of the cleaning device. Therefore, after the duration of the cleaning device in the first state satisfies the first set time, while controlling the prompting device to be in the on state to issue a liquid replenishment prompt to the user, the cleaning device can be controlled to stop operating to avoid the cleaning component cleaning the floor without sufficient liquid wetting, thereby avoiding affecting the floor cleaning effect and damaging the cleaning component.

[0120] In the above embodiment, under another condition, if it is determined at the 7th second that the cleaning device has entered a first state indicating insufficient liquid, then the conditions of steps 3222 to 3223 described above are satisfied, namely, the reaction time of the cleaning device (i.e., the time between the time when the cleaning device is determined to have entered the first state (the 7th second) and the start time of the cleaning device (the 1st second) is 6 seconds) is greater than the second set time (5 seconds). In this case, it indicates that the cleaning device has continuously collected the first signal 60 times within the time period from the 4th second to the 6th second, thereby indicating that there is liquid in the liquid pipeline from the 1st second to the 3rd second. That is to say, at the 7th second, the liquid present in the liquid pipeline from the 1st second to the 3rd second is delivered to the cleaning component of the cleaning device, and the liquid present from the 1st second to the 3rd second is sufficient to wet the cleaning component of the cleaning device. Therefore, after the cleaning equipment has been in the first state for a set duration, while the prompting device is turned on to send a liquid replenishment reminder to the user, it is not necessary to stop the cleaning equipment. Instead, the cleaning equipment can continue to perform the cleaning action to avoid disrupting the continuity of the cleaning action and affecting the user experience. Furthermore, if the cleaning equipment has been in the first state for a set duration (e.g., 120 seconds or 110 seconds, the third set duration can be set according to actual conditions, and this application does not impose further limitations on it), it can be determined that the cleaning components in the cleaning equipment are no longer wet. If the user has not replenished the liquid at this point, the cleaning equipment can be stopped, and a liquid replenishment reminder can be sent to the user again. This avoids cleaning the floor with insufficient liquid, thus preventing damage to the cleaning components and affecting the floor cleaning effect.

[0121] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include step 328:

[0122] Step 328: Within a fourth set time period after the cleaning equipment switches cleaning gears or cleaning modes, the prompting device is controlled to be in a closed state.

[0123] Furthermore, after the fourth set duration, it is determined whether to continue controlling the prompting device to remain in the off state.

[0124] In this application, the fourth set duration can be 5 seconds, 4 seconds, or 6 seconds. Specifically, the fourth set duration can be set according to the actual situation, and this application does not impose too many restrictions on it.

[0125] During the operation of the cleaning equipment, if a change in cleaning level or mode occurs, the notification device will be kept off for a fourth set time period after the change. Only after the fourth set time period has elapsed will the decision to keep the notification device off be reassessed. This prevents overlap or interference between the switching notification and the liquid replenishment notification when the user changes levels or modes. By determining whether to keep the notification device off after the fourth set time period, unnecessary notification interference is reduced, thereby improving the user experience.

[0126] In this application, the step of analyzing the liquid signal based on the first mode and controlling the opening or closing of the prompting device based on the obtained first analysis result may further include step 329:

[0127] Step 329: When the cleaning equipment is in water absorption mode, control the prompting device to be in the off state.

[0128] In suction mode, the cleaning device is drawing liquid from the external environment, so immediate liquid replenishment is not required. By keeping the indicator device off, liquid replenishment reminders are disabled, preventing unnecessary distractions and allowing the user to focus on the current cleaning task. This also prevents users from performing unnecessary actions due to mistakenly believing liquid needs to be added, improving device usability and user experience.

[0129] Furthermore, after the cleaning device switches from absorbent mode to non-absorbent mode, the current liquid status can be reassessed to determine whether to continue keeping the indicator device off. This is beneficial because the cleaning device relies on its internally stored liquid for cleaning in non-absorbent mode, thus ensuring sufficient liquid is essential. By assessing the situation after switching to non-absorbent mode, the user can be promptly prompted to replenish the liquid, preventing insufficient liquid from affecting cleaning performance and effectively ensuring the continuity and efficiency of the cleaning task.

[0130] Next, this application will provide a detailed description of the second mode.

[0131] In this application, the step of analyzing the liquid signal based on the second mode and controlling the liquid heating device to turn on or off based on the obtained second analysis result may include the following step 331:

[0132] Step 331: If the number of times the liquid signal is the second signal continuously reaches a third set number, then the cleaning equipment is determined to be in the third state. The second signal indicates that there is liquid at the location of the detection device. The third state includes sufficient liquid in the cleaning equipment.

[0133] In this application, if the number of times the liquid signal continuously corresponds to the second signal reaches a third predetermined number, the cleaning device is determined to enter a third state (also called a water-containing state). For example, if the number of times the liquid signal continuously corresponds to the second signal reaches 40 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the second signal is 2 seconds), the cleaning device is determined to enter the third state. Or, for example, if the cleaning device continuously acquires the second signal 60 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the second signal is 3 seconds), the cleaning device is determined to enter the third state.

[0134] In this application, the number of times the third setting can be set according to the actual situation, and this application does not make specific limitations on it.

[0135] The execution device of the cleaning equipment control method may store a character for recording the state of the cleaning equipment corresponding to the liquid heating device. For ease of description, we define this character as the second character. In the scenario corresponding to the liquid heating device, when the cleaning equipment enters the third state, the value of the second character can be the character value corresponding to the third state.

[0136] In this application, the step of analyzing the liquid signal based on the second mode and controlling the liquid heating device to turn on or off based on the obtained second analysis result may further include the following step 332:

[0137] Step 332: If the cleaning equipment is in the third state, then control the liquid heating device to be in the on state.

[0138] In this application, the liquid state is determined by liquid signals collected by a detection device in the liquid pipeline. If the number of consecutive acquisitions of a second signal reflecting the presence of liquid in the pipeline reaches a third predetermined number, the cleaning equipment is determined to have entered a third state indicating sufficient liquid, and the liquid heating device is controlled to be turned on, thus enabling the liquid heating device of the cleaning equipment to operate. This effectively avoids misjudgments caused by occasional signal interference or brief liquid fluctuations, ensuring that the liquid heating device only operates when the liquid in the cleaning equipment is truly sufficient. This not only improves the safety and reliability of the cleaning equipment but also reduces unnecessary energy consumption and extends the service life of the cleaning equipment. Simultaneously, through automated liquid state monitoring and liquid heating device control, the reliability of the control of the cleaning equipment is guaranteed, eliminating the need for frequent manual intervention by the user and improving the convenience and experience of use.

[0139] In this application, the step of analyzing the liquid signal based on the second mode and controlling the liquid heating device to turn on or off based on the obtained second analysis result may further include the following step 333:

[0140] Step 333: If the number of times the liquid signal is the first signal continuously reaches a fourth predetermined number, then the cleaning device is determined to be in the fourth state. The first signal indicates that there is no liquid at the location of the detection device, and the fourth state includes insufficient liquid in the cleaning device.

[0141] Furthermore, in this application, the step of analyzing the liquid signal based on the second mode and controlling the liquid heating device to turn on or off based on the obtained second analysis result may further include the following step 334:

[0142] Step 334: If it is determined that the cleaning equipment is in the fourth state, then control the liquid heating device to be in the off state.

[0143] In this application, if the number of times the liquid signal continuously corresponds to the first signal reaches a fourth predetermined number, the cleaning device is determined to enter a fourth state (i.e., the cleaning device is determined to be in a state of insufficient liquid, also known as a water shortage state). For example, if the number of times the liquid signal continuously corresponds to the first signal reaches 20 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of continuous acquisition of the first signal is 1 second), the cleaning device is determined to enter the fourth state. Or, for example, if the number of times the liquid signal continuously corresponds to the first signal reaches 30 times (if the frequency of liquid signal acquisition is 50 milliseconds / time, then the duration of acquisition of the first signal is 1.5 seconds), the cleaning device is determined to enter the fourth state. After determining that the cleaning device has entered the fourth state, the liquid heating device can be controlled to be in a closed state, so that the liquid heating device of the cleaning device stops operating.

[0144] In this application, the fourth setting number can be set according to the actual situation, and this application does not make a specific limitation on it.

[0145] In the scenario corresponding to the liquid heating device, when the cleaning device enters the fourth state, the value of the second character can be the character value corresponding to the fourth state.

[0146] In this application, once the liquid in the cleaning equipment is detected to be insufficient, the liquid heating device can be immediately shut off to prevent the liquid heating device from burning dry and damaging the liquid heating device and the cleaning equipment. This improves the safety and service life of the cleaning equipment, while optimizing energy utilization and reducing unnecessary power consumption.

[0147] In this application, the following step 335 may also be performed:

[0148] Step 335: If the cleaning device is started, for example, in hot water mode or steam mode, the cleaning device is triggered to perform the liquid heating device protection task, and the cleaning device is determined to enter the fourth state.

[0149] In this application, when the cleaning equipment starts, it automatically triggers a protection task for the liquid heating device, ensuring that the cleaning equipment protects the liquid heating device after each startup. Furthermore, during the execution of the liquid heating device protection task, the cleaning equipment determines that it has entered a fourth state indicating insufficient liquid upon startup. This has the advantage of preventing the situation where insufficient liquid is mistakenly interpreted as sufficient liquid. In some special cases, such as when first using the cleaning equipment, the user may neglect to check if the liquid level is sufficient. In this situation, if the cleaning equipment has insufficient liquid upon startup, the presence of a small amount of liquid in the liquid lines may be mistakenly interpreted as a sufficient liquid state (third state), potentially leading to incorrect control of the liquid heating device, causing it to burn dry and damaging both the liquid heating device and the cleaning equipment. Therefore, this application avoids this situation, thereby improving the safety and lifespan of the cleaning equipment, while optimizing energy utilization and reducing unnecessary power consumption.

[0150] To enable those skilled in the art to better understand this application, the following is combined with Figure 5 The following is an illustration using a specific example.

[0151] Reference Figure 5 The diagram shows a control flowchart of the cleaning equipment in an embodiment of this application.

[0152] In one embodiment of this application, the sampling frequency of liquid signals in the liquid pipeline can be set to 50 milliseconds / time, that is, it takes 2 seconds to continuously sample 40 liquid signals and 1 second to continuously sample 20 liquid signals.

[0153] Furthermore, such as Figure 5 As shown, after the cleaning equipment is started, it can be determined that the cleaning equipment has entered a fourth state indicating insufficient liquid during the execution of the liquid heating device protection task. At this time, the liquid heating device can be controlled to be turned off, so that the liquid heating device of the cleaning equipment stops operating. Further, if the second signal is collected 40 times consecutively (i.e., the third set number of times), it is determined that the cleaning equipment has entered a third state indicating sufficient liquid. At this time, the liquid heating device of the cleaning equipment can be controlled to operate. If the first signal is collected 20 times consecutively (i.e., the fourth set number of times), it is determined that the cleaning equipment has entered a fourth state indicating insufficient liquid. At this time, the liquid heating device of the cleaning equipment can be controlled to stop operating.

[0154] In this application, the fourth set number of times can be less than the third set number of times. This has the advantage of enhancing the sensitivity to detecting insufficient liquid in the cleaning equipment, allowing for a faster response to insufficient liquid conditions and timely control of the liquid heating device to shut it off, thus preventing dry burning. In this way, determining the liquid state of the cleaning equipment by collecting liquid signals through a set number of consecutive times eliminates the impact of fluctuations in detection values ​​caused by liquid and air mixing in the liquid pipeline. This ensures normal operation of the cleaning equipment while minimizing the risk of damage due to insufficient liquid, thereby improving the safety and reliability of the cleaning equipment. Furthermore, this rapid response mechanism helps reduce unnecessary energy consumption, improves energy efficiency, and extends the service life of the cleaning equipment.

[0155] In this application, step 336 may also be performed:

[0156] Step 336: If the number of times the cleaning device continuously acquires the second signal in the fourth state does not reach the third preset number, then it is determined that the cleaning device remains in the fourth state.

[0157] In this application, the cleaning equipment can track the number of consecutive times it receives the second signal in the fourth state. If this consecutive number does not reach a preset third set number, the cleaning equipment determines that it is still in the fourth state. This avoids misjudgments caused by occasional factors or brief fluctuations (i.e., avoiding misjudgments of the cleaning equipment entering the third state due to the receipt of scattered second signals in the fourth state), thus ensuring that the cleaning equipment's judgment of its liquid state has a certain degree of anti-interference capability. It also ensures that the cleaning equipment will not arbitrarily determine that it has entered the third state, which indicates sufficient liquid, when the liquid is insufficient (i.e., it will not arbitrarily control the operation of the cleaning equipment's liquid heating device). Therefore, by reducing the sensitivity of monitoring the liquid state under the protection task of the liquid heating device, the influence of detection value fluctuations caused by the mixing of liquid and air in the liquid pipeline on the detection results can be eliminated, improving the reliability of the cleaning equipment's liquid state monitoring and the reliability of liquid replenishment prompts, thereby enhancing the user's trust in the operating status of the cleaning equipment.

[0158] In this application, step 337 may also be performed:

[0159] Step 337: If the number of times the cleaning device continuously acquires the first signal in the third state does not reach the fourth preset number, then it is determined that the cleaning device remains in the third state.

[0160] In this application, the cleaning device can track the number of consecutive times it receives the first signal in the third state. If this consecutive number does not reach a preset fourth number, the cleaning device determines that it is still in the third state. In this way, misjudgments caused by occasional factors or brief fluctuations can be avoided (i.e., avoiding misjudgment that the cleaning device has entered the fourth state due to the acquisition of scattered first signals in the third state). This ensures that the cleaning device has a certain anti-interference capability in judging its liquid status, and guarantees that the cleaning device will not arbitrarily determine that it has entered the fourth state indicating insufficient liquid when the liquid is sufficient (i.e., it will not arbitrarily control the liquid heating device of the cleaning device to stop operating). Furthermore, by reducing the sensitivity of monitoring the liquid status under the protection task of the liquid heating device, the influence of the detection value fluctuation caused by the mixing of liquid and air in the liquid pipeline on the detection results can be eliminated, improving the reliability of the cleaning device's liquid status monitoring and the reliability of liquid replenishment prompt information, thereby enhancing the user's confidence in the operation of the cleaning device.

[0161] In this application, liquid signals in the liquid pipeline are analyzed in parallel using different modes. Based on the different analysis results, the activation and deactivation of the indicator device and the liquid heating device in the cleaning equipment are controlled separately. This satisfies the different sensitivity requirements of the indicator device and the liquid heating device for liquid signal analysis. While reducing false alarms from the indicator device, it also reduces the risk of dry burning of the liquid heating device, achieving a dual protection mechanism for the cleaning equipment. This ensures flexible response to changes in liquid state under different usage scenarios. Therefore, the technical solution proposed in this application can simultaneously achieve precise control of the indicator device and the liquid heating device according to their different sensitivity requirements for liquid detection.

[0162] In summary, this application employs a conservative approach to the liquid replenishment alert function to avoid falsely reporting a low-liquidity status of the cleaning equipment before the liquid has fully reached the detection device, thus reducing unnecessary user intervention. This approach ensures that the user is only alerted when liquid replenishment is truly needed, preserving the user experience. Simultaneously, the liquid heating device protection function utilizes a more sensitive approach to ensure that once the cleaning equipment is detected as low on liquid, measures are immediately taken to stop the operation of the liquid heating device, preventing dry burning. This highly sensitive approach effectively protects the liquid heating device, preventing equipment damage due to overheating.

[0163] By executing these two modes in parallel, the cleaning equipment can monitor the liquid status at different levels, improving the user experience while ensuring the safety and reliability of the equipment. This dual-mode implementation not only optimizes the equipment's liquid management but also extends its lifespan and reduces maintenance costs.

[0164] Furthermore, if the control logic for the liquid replenishment prompt task is executed simultaneously with the control logic for the liquid heating device protection task, the third set number of times can be less than the first set number of times.

[0165] In this application, by limiting the third set number of times to less than the first set number of times, the control mode under the liquid heating device protection task can be more sensitive than the control mode under the liquid replenishment reminder task, and conversely, the control mode under the liquid replenishment reminder task can be more conservative than the control mode under the liquid heating device protection task.
