[0031] This application also provides a computer-readable storage medium storing at least one computer program instruction, which is loaded and executed by a processor to perform the operations described above.

[0032] This application also provides a cleaning system, which includes a base station and the cleaning equipment described above.

[0033] Based on the cleaning equipment proposed in this application, the equipment can dynamically adjust the flow rate of liquid supplied to the heater by the liquid pump by real-time monitoring of the heater temperature. This ensures the stable generation of hot liquid that meets the corresponding temperature requirements within the cleaning equipment, guaranteeing the reliability of cleaning tasks performed in hot liquid mode. Specifically, when the heater temperature remains below a first temperature for an extended period, reducing the flow rate of liquid supplied to the heater ensures that a unit volume of liquid absorbs more heat, thereby increasing the heater temperature (i.e., increasing the temperature of the liquid in the heater). This adaptive flow regulation mechanism ensures that the temperature of the liquid flowing out of the cleaning equipment in hot liquid mode is not too low, thus improving the cleaning effect, increasing the efficiency and quality of the cleaning task, and guaranteeing the reliability of the cleaning equipment in hot liquid mode.

[0034] Furthermore, the cleaning equipment can dynamically adjust the heater's on / off state by monitoring the heater temperature in real time, thereby stably generating hot liquid that meets the corresponding temperature requirements and ensuring reliability in hot liquid mode. Specifically, when the heater temperature is lower than the second temperature, controlling the heater to start operation can output heat to the liquid in the heater, thereby raising the heater temperature (i.e., raising the temperature of the liquid in the heater). This adaptive heater start / stop adjustment mechanism ensures that the temperature of the liquid flowing out of the cleaning equipment in hot liquid mode is dynamically maintained above the second temperature, thus improving the efficiency and quality of the cleaning equipment in performing cleaning tasks and ensuring the reliability of the cleaning equipment in hot liquid mode.

[0035] Overall, the cleaning equipment proposed in this application enables the heater and liquid pump to work in tandem, ensuring the stability and continuity of the hot liquid supply. By synchronously adjusting the flow rate of the liquid pump supplying the heater and the start / stop status of the heater, the generation and delivery rate of the hot liquid can be precisely controlled, thereby optimizing the cleaning effect. Furthermore, by incorporating dual control logic, if one control strategy malfunctions, the other control strategy can be adjusted to maintain the overall stability of the cleaning equipment in hot liquid mode, further enhancing the reliability of the cleaning equipment.

[0048] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0049] To enable those skilled in the art to better understand this application, a brief description of the cleaning equipment and its system architecture involved in this application will first be given with reference to Figure 1.

[0050] Figure 1 illustrates 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 heater liquid pump 107, a pressure relief valve 108, a heater 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).

[0051] The liquid tank 101 stores liquid, which can be clean water or other liquids suitable for cleaning floors or cleaning components; this application does not specifically limit the type of liquid. The liquid detection device 102 detects the flow rate in the liquid pipeline and determines whether flowing liquid is present. The heater liquid pump 107 pumps a set flow rate of liquid into the heater 109, causing the heater 109 to heat the liquid and generate steam. The steam then flows through the first reversing valve 111 to the steam nozzle 112, ultimately being sprayed onto the ground. The liquid pump 113 can pump a larger set flow rate of liquid into the heater 109 via the second reversing valve 114, causing the heater 109 to heat the liquid and generate a hot liquid. This hot liquid then flows through the first reversing valve 111 to the cleaning component 116 for cleaning the floor or cleaning the component. The liquid pump 113 can also directly pump a cooler liquid (at room temperature) into the cleaning component 116 via the second reversing valve 114 for cleaning the floor or cleaning the component.

[0052] 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 adapt to different functional 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, in which the cleaning agent pump 105 pumps the cleaning agent in the cleaning agent tank 104 into the second three-way valve 106 to deliver the cleaning agent to the entire liquid pipeline.

[0053] Specifically, in the cold liquid mode, the second reversing valve 114 is closed, and 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 heater 109, the liquid flowing to the cleaning component 116 is in a low-temperature liquid state (such as a room-temperature liquid state).

[0054] In hot liquid mode, both the first reversing valve 111 and the second reversing valve 114 are in the open state. 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 heater 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 heater 109, the liquid flowing to the cleaning component 116 is in a high-temperature liquid state, which can enhance the cleaning effect on the ground or the cleaning component.

[0055] In steam mode, the first reversing valve 111 is closed, and the liquid flows sequentially through the liquid detection device 102, the first three-way valve 103, the heater liquid pump 107, the pressure relief valve 108, the heater 109, the filter screen 110, the first reversing valve 111, and the steam port 112. Because the liquid passes through the heater liquid pump 107 and is heated by the heater 109, the liquid flowing to the steam port 112 is in a high-temperature gaseous state, which can enhance the cleaning effect on the ground.

[0056] In practical applications, cleaning equipment uses a liquid pump to supply liquid to the cleaning components when cleaning the floor, which wets the components and facilitates the removal of stains. Furthermore, cleaning equipment with a hot liquid mode, when cleaning the floor, releases hot liquid into the cleaning components. This softens solid stains on the floor, making them easier to clean, and also kills microorganisms on the floor at high temperatures. This significantly improves the cleaning effect. However, it is crucial to ensure the reliable execution of cleaning tasks in hot liquid mode by stably generating hot liquid that meets specific temperature requirements. Therefore, this application proposes several embodiments of a cleaning equipment and its control method to ensure the reliability of the cleaning equipment in hot liquid mode.

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

[0058] Before proceeding, it should be noted that, to enable those skilled in the art to better understand this application, this application will provide some embodiments including control parameters. In these embodiments, the specific values ​​of the control parameters are given with reference to the assumption that the liquid is clean water. For the sake of brevity, this application will not elaborate on this further in the subsequent description. Furthermore, the specific values ​​of the control parameters in the embodiments are merely exemplary; in practical applications, the control parameters in the embodiments may also be other values ​​depending on the actual situation.

[0059] Referring to FIG2, the cleaning device 100 proposed in this application may include a heater 109, a liquid pump 113, a temperature detection device 117, and a controller 300.

[0060] The heater 109 is configured to heat liquid; the liquid pump 113 is connected to the heater 109 and is configured to supply liquid to the heater 109; the temperature detection device 117 is located on the heater 109 and is configured to collect the temperature of the heater; the controller 300 is communicatively connected to the heater 109, the liquid pump 113, and the temperature detection device 117.

[0061] Referring again to Figure 2, in this application, the controller 300 can be configured to: acquire the heater temperature collected by the temperature detection device 117 in hot liquid mode; if the duration of the heater temperature being lower than a first temperature is greater than a first duration, control the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109.

[0062] In this application, the temperature detection device 117 may be a negative temperature coefficient thermistor (NTC), a thermocouple, an infrared temperature sensor (ITS), a semiconductor temperature sensor (STS), or a bimetallic temperature sensor (BTS). This application does not make any specific limitation in this regard.

[0063] In this application, the first temperature can be in the range of 55-65 degrees Celsius. For example, the first temperature could be 59 degrees Celsius, 60 degrees Celsius, or 61 degrees Celsius. It should be understood that the first temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0064] In this application, the first duration can be between 15 and 25 seconds. For example, the first duration can be 19 seconds, 20 seconds, or 21 seconds. It should be understood that the first duration can be set according to actual needs, and this application does not impose any specific limitations on it.

[0065] Based on the technical solution proposed in this application, the cleaning equipment 100 can dynamically adjust the flow rate of liquid supplied by the liquid pump 113 to the heater 109 by real-time monitoring of the heater temperature. This allows for the stable generation of hot liquid that meets the corresponding temperature requirements within the cleaning equipment 100, ensuring the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode. Specifically, when the heater temperature remains below a first temperature for an extended period, reducing the flow rate of liquid supplied to the heater 109 ensures that a unit volume of liquid can absorb more heat, thereby increasing the heater temperature (i.e., effectively increasing the temperature of the liquid in the heater 109). This adaptive flow regulation mechanism ensures that the temperature of the liquid flowing out of the cleaning equipment 100 in hot liquid mode is not too low, thus improving the cleaning effect of the cleaning equipment 100 on the ground in hot liquid mode, enhancing the efficiency and quality of the cleaning tasks performed by the cleaning equipment 100, and overall ensuring the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode.

[0066] Furthermore, in this application, the controller 300 can also be configured to: if the duration for which the heater temperature is lower than the first temperature is greater than the first duration, control the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109 according to the first flow rate amplitude (ml / min); after controlling the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109 according to the first flow rate amplitude (ml / min), restart the timing to determine whether the duration for which the heater temperature is lower than the first temperature is greater than the first duration.

[0067] In this application, the value range of the first flow rate amplitude can be 2-4 ml / min. For example, the first flow rate amplitude can specifically be 2.9 ml / min, 3 ml / min, or 3.1 ml / min. It should be understood that the first flow rate amplitude can be set according to actual needs, and this application does not impose specific limitations on it.

[0068] In this application, it is understood that after re-timing, if the duration for which the heater temperature is lower than the first temperature is still greater than the first duration, the liquid pump 113 can be controlled to reduce the flow rate of liquid supplied to the heater 109 according to the first flow rate amplitude, and so on, until the condition that the duration for which the heater temperature is lower than the first temperature is no longer satisfied is met.

[0069] To enable those skilled in the art to better understand this application, a specific embodiment will be described below.

[0070] In one specific embodiment, the liquid pump 113 supplies liquid to the heater 109 at a flow rate of 60 ml / min, the first temperature is 60 degrees, the first duration can be 20 seconds, and the first flow rate amplitude can be 3 ml / min.

[0071] In this embodiment, when the flow rate of liquid supplied by the liquid pump 113 to the heater 109 is controlled at 60 ml / min, if the duration of the heater temperature being 55 degrees (less than 60 degrees) is greater than 20 seconds, then the flow rate of liquid supplied by the liquid pump 113 to the heater 109 is controlled at 60 ml / min - 3 ml / min = 57 ml / min, and the timing is reset.

[0072] If the flow rate of liquid supplied by liquid pump 113 to heater 109 is controlled at 57 ml / min, and the duration of the heater temperature being 58 degrees (less than 60 degrees) is greater than 20 seconds, then the flow rate of liquid supplied by liquid pump 113 to heater 109 can be controlled at 57 ml / min - 3 ml / min = 54 ml / min, and the timing can be reset.

[0073] If the flow rate of liquid supplied by the liquid pump 113 to the heater 109 is controlled at 54 ml / min, and the duration of the heater temperature being less than 60 degrees is only 10 seconds (i.e., the heater temperature exceeds 60 degrees at the 11th second), then it indicates that the condition that the duration of the heater temperature being less than the first temperature is not met is not satisfied, and therefore it is not necessary to continue controlling the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109.

[0074] It is understood that, based on the control logic of the above embodiments, the heater temperature (i.e., the temperature of the heater 109 collected by the temperature detection device 117) can be dynamically stabilized at 60 degrees or above.

[0075] In this application, when the heater temperature is at a low level (i.e., the heater temperature remains below the first temperature for an extended period), by gradually reducing the flow rate of liquid supplied to the heater 109 by controlling the liquid pump 113, the heat absorbed by a unit volume of liquid per unit time can be increased. This increases the rate of increase in liquid temperature per unit time, ultimately raising the temperature of the liquid in the heater 109. Specifically, the heater temperature is stabilized at or above the first temperature. As a result, the liquid temperature in the heater 109 meets the requirements for liquid temperature in the hot liquid mode, thereby achieving stable generation of hot liquid in the cleaning equipment 100. This improves the cleaning effect of the cleaning equipment 100 on the ground in the hot liquid mode, enhances the efficiency and quality of the cleaning equipment 100 in performing cleaning tasks, and ensures the reliability of the cleaning equipment 100 in performing cleaning tasks in the hot liquid mode.

[0076] Referring again to Figure 2, in this application, the controller 300 can also be configured to: if the heater temperature is greater than a third temperature, control the liquid pump 113 to increase the flow rate of liquid supplied to the heater 109, wherein the third temperature is greater than the first temperature.

[0077] In this application, the value range of the third temperature can be 65-75 degrees Celsius. For example, the third temperature can specifically be 67 degrees Celsius, 68 degrees Celsius, or 69 degrees Celsius. It should be understood that the third temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0078] In this application, when the heater temperature is high (i.e., above the third temperature), increasing the flow rate of liquid supplied to heater 109 reduces the heat absorbed per unit volume of liquid, thereby lowering the heater temperature (i.e., lowering the temperature of the liquid in heater 109). This adaptive flow regulation mechanism ensures that the liquid temperature flowing out of the cleaning device 100 in hot liquid mode is not excessively high, thus avoiding safety issues caused by excessively high liquid temperatures. For example, it prevents the liquid in heater 109 from boiling over, and avoids the situation where scalding liquid sprays out due to excessively high internal temperature and pressure in heater 109. This ensures the safety of the cleaning device 100 in hot liquid mode.

[0079] In general, based on the above scheme, the heater temperature can be controlled between the first temperature and the third temperature, thereby keeping the temperature of the liquid in heater 109 within a reasonable range in hot liquid mode, that is, neither too low nor too high. This control method ensures the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode.

[0080] Furthermore, in this application, the controller 300 can also be configured to: if the heater temperature is greater than the third temperature, control the liquid pump 113 to increase the flow rate of liquid supplied to the heater 109 according to a second flow rate amplitude of ml / min, wherein the second flow rate amplitude is positively correlated with the value by which the heater temperature exceeds the third temperature; after controlling the liquid pump 113 to increase the flow rate of liquid supplied to the heater 109 according to the second flow rate amplitude of ml / min, re-determine whether the heater temperature is greater than the third temperature.

[0081] In this application, for every 1 degree Celsius the heater temperature exceeds the third temperature, the increase in the second flow rate amplitude can be between 2 and 4 ml / min. For example, the increase could be 2.9 ml / min, 3 ml / min, or 3.1 ml / min. It should be understood that the increase in the second flow rate amplitude can be set according to actual needs, and this application does not impose any specific limitations on it.

[0082] In this application, it is understood that the greater the difference between the heater temperature and the third temperature, the greater the second flow rate amplitude.

[0083] To enable those skilled in the art to better understand this application, a specific embodiment will be described below.

[0084] In one specific embodiment, the liquid pump 113 supplies liquid to the heater 109 at a flow rate of 60 ml / min, the third temperature is 68 degrees, and the increase in the second flow rate amplitude can be 3 ml / min.

[0085] In this embodiment, when the flow rate of liquid supplied by liquid pump 113 to heater 109 is controlled to be 60 ml / min, if the heater temperature is 70 degrees (2 degrees above 68 degrees), the flow rate of liquid supplied by liquid pump 113 to heater 109 can be controlled to be 60 ml / min + 3 ml / min × 2 = 66 ml / min.

[0086] In this embodiment, when the flow rate of liquid supplied by liquid pump 113 to heater 109 is controlled to be 60 ml / min, if the heater temperature is 69 degrees (the excess value relative to 68 degrees is 1 degree), the flow rate of liquid supplied by liquid pump 113 to heater 109 can be controlled to be 60 ml / min + 3 ml / min = 63 ml / min.

[0087] It is understood that, based on the control logic of the above embodiments, the heater temperature (i.e., the temperature of the heater 109 collected by the temperature detection device 117) can be dynamically stabilized at 68 degrees or below.

[0088] In this application, based on the degree to which the heater temperature exceeds the third temperature, the flow rate is increased accordingly, based on the current flow rate of liquid supplied to the heater 109 by the liquid pump 113. This reduces the heat absorbed per unit volume of liquid per unit time, thereby slowing the rise in liquid temperature and ultimately stabilizing the liquid temperature in the heater 109 at or below the third temperature. This keeps the heater temperature within a range that is neither too low nor too high, ensuring that the liquid temperature in the heater 109 meets the requirements of the hot liquid mode. This process achieves the effect of stably generating hot liquid in the cleaning equipment 100, which not only improves the cleaning effect of the cleaning equipment 100 on the ground in hot liquid mode but also ensures its operational safety, thereby improving the efficiency and quality of the cleaning equipment 100 in performing cleaning tasks and ensuring its reliability in hot liquid mode.

[0089] In this application, the controller 300 can also be configured to control the flow rate of liquid supplied by the liquid pump 113 to the heater 109 to be less than or equal to the upper limit of the liquid supply flow rate of the liquid pump 113.

[0090] In this application, the upper limit of the liquid supply flow rate of the liquid pump 113 can be 70 ml / min, 71 ml / min, or 72 ml / min. It should be understood that the upper limit of the liquid supply flow rate of the liquid pump 113 can be set according to actual needs, and this application does not make specific limitations in this regard.

[0091] In this application, by controlling the flow rate of liquid supplied by liquid pump 113 to heater 109 to be less than or equal to the upper limit of liquid supply flow rate of liquid pump 113, on the one hand, it can prevent liquid pump 113 from increasing the flow rate of liquid supplied to heater 109 without limit, and prevent the normal operation of cleaning equipment 100 from being affected by excessive liquid supply flow rate. On the other hand, it can prevent liquid pump 113 from operating under overload, reduce the risk of liquid pump 113 failure, and thus improve the overall stability and reliability of cleaning equipment 100.

[0092] Referring again to FIG2, in this application, the cleaning equipment 100 may further include a liquid detection device 102, wherein the liquid detection device 102 may be configured to detect whether there is flowing liquid in the liquid pipeline of the cleaning equipment 100.

[0093] Furthermore, the controller 300 can also be configured to: if the duration of flowing liquid in the liquid pipeline of the cleaning equipment 100 meets a second duration, then control the liquid pump 113 to start running; if the duration of no flowing liquid in the liquid pipeline meets a third duration, then control the liquid pump 113 to stop running, wherein the third duration is less than the second duration.

[0094] In this application, the liquid detection device 102 can be a flow meter or a level gauge, and this application does not specifically limit it.

[0095] In this application, the second duration can be in the range of 1.5-2.5 seconds; for example, the second duration can specifically be 2 seconds or 2.2 seconds. The third duration can be in the range of 0.5-1.5 seconds; for example, the third duration can specifically be 1 second or 1.2 seconds. It should be understood that the second and third durations can be set according to actual needs, and this application does not impose specific limitations on them.

[0096] In this application, if there is no continuous flow of liquid in the liquid pipeline of the cleaning equipment 100 within a third time period, an alarm can be issued to remind the user to add liquid to the cleaning equipment 100 in a timely manner.

[0097] In this application, on the one hand, after the cleaning equipment 100 enters the hot liquid mode, by detecting the liquid in the liquid pipeline of the cleaning equipment 100 and controlling the liquid supply delay, it is possible to effectively prevent the liquid pump 113 from starting when there is no liquid or insufficient liquid in the liquid pipeline, which would trigger the start of the heater 109 and avoid damage to components or safety accidents caused by the heater 109 burning out. On the other hand, based on the confirmation that there is liquid flow in the liquid pipeline, by delaying the control of the liquid pump 113 to supply liquid to the heater 109 for a second time, it is possible to ensure that the liquid flows stably to the heater 109, thereby avoiding the situation where the heater 109 burns out due to unstable liquid flow or incomplete liquid flow in the liquid pipeline. Therefore, this application can improve the operational safety, operational reliability, and service life of the cleaning equipment 100 in the hot liquid mode.

[0098] Referring again to Figure 2, in this application, the controller 300 can also be configured to: stop supplying liquid to the heater 109 and control the heater 109 to stop operating within a fourth time period after the cleaning device 100 enters the hot liquid mode.

[0099] In this application, the fourth duration can be between 2 and 13 seconds. For example, the fourth duration can specifically be 5 seconds, 6 seconds, or 7 seconds. It should be understood that the fourth duration can be set according to actual needs, and this application does not impose any specific limitations on it.

[0100] In this application, the cleaning device 100 may include a mode trigger (not shown in the figure), which can at least be used by a user to trigger the cleaning device 100 to enter a steam mode, a hot liquid mode, or a cold liquid mode.

[0101] In this application, the mode trigger may include buttons or voice control devices on the cleaning device 100, or an APP installed on a mobile phone or computer for controlling the cleaning device. Specifically, this application does not impose further limitations. It is understood that through the mode trigger, users can conveniently trigger steam mode, hot liquid mode, or cold liquid mode according to actual needs, thereby achieving convenient switching of the working mode of the cleaning device 100.

[0102] In this application, when the cleaning device 100 is triggered to enter steam mode, hot liquid mode, or cold liquid mode, the controller 300 can control the cleaning device 100 to switch to the corresponding working mode and issue corresponding prompts to the user within a certain period of time. For example, if the user triggers the cleaning device 100 to enter hot liquid mode, the cleaning device 100 will switch its working mode to hot liquid mode and announce "Switched to hot liquid mode" via voice broadcast or display the text message "Switched to hot liquid mode" on the user interface. In this way, the user can intuitively understand which working mode the cleaning device 100 is currently in.

[0103] In this application, since the cleaning device 100 shares the heater 109 in both steam and hot liquid modes, and the heater 109 employs flow-through heating in hot liquid mode, the heater will fill with liquid. Therefore, when the cleaning device 100 is triggered to enter hot liquid mode, by controlling the liquid pump 113 to stop supplying liquid to the heater 109 within a fourth time period and controlling the heater 109 to stop operating, the user can clearly understand the actual operating mode of the cleaning device 100 during this period. If the actual operating mode is hot liquid mode, and the user wishes to switch to steam mode, the user can actively switch after confirming the current mode. This avoids the situation where the heater 109 fills with liquid due to the user's misunderstanding of the operating mode of the cleaning device 100 or accidental triggering of the hot liquid mode.

[0104] Based on the technical solution proposed in this application, when the cleaning equipment 100 enters the hot liquid mode, by stopping the liquid supply of the liquid pump 113 within a fourth time period and controlling the heater 109 to stop operating, the user can realize that the cleaning equipment 100 is in the hot liquid mode according to the prompt information within the fourth time period, and further switch the working mode to the steam mode. At this time, since the heater is not full of liquid, the steam generation time of the cleaning equipment in the steam mode will not be prolonged, thereby improving the efficiency of the cleaning equipment in performing cleaning tasks in the steam mode and enhancing the user experience.

[0105] Referring again to Figure 2, in this application, the controller 300 can also be configured as follows: if the cumulative operating time of the cleaning equipment 100 in the same start-up cycle is less than or equal to the fifth duration, then the first flow rate is determined as the initial flow rate of the liquid pump 113 supplying liquid to the heater 109 in hot liquid mode; if the cumulative operating time of the cleaning equipment 100 in the same start-up cycle is greater than the fifth duration, then the second flow rate is determined as the initial flow rate of the liquid pump 113 supplying liquid to the heater 109 in hot liquid mode, wherein the second flow rate is less than the first flow rate.

[0106] In some embodiments, a power-on cycle may refer to the time period during which the cleaning device 100 is powered on and used after being fully charged until the power of the cleaning device 100 is exhausted (i.e., it is not turned off during the entire process).

[0107] In this application, the value range of the fifth duration can be 8-15 minutes. For example, the fifth duration can specifically be 9 minutes, 10 minutes, or 11 minutes. It should be understood that the fifth duration can be set according to actual needs, and this application does not impose a specific limitation on it.

[0108] In this application, the first flow rate can be in the range of 55-65 ml / min. For example, the first flow rate can specifically be 59 ml / min, 60 ml / min, or 61 ml / min. It should be understood that the first flow rate can be set according to actual needs, and this application does not impose specific limitations on it.

[0109] In this application, the second flow rate can be in the range of 35-45 ml / min. For example, the second flow rate can specifically be 39 ml / min, 40 ml / min, or 41 ml / min. It should be understood that the second flow rate can be set according to actual needs, and this application does not impose specific limitations on it.

[0110] In this application, the second flow rate is limited to be less than the first flow rate. This has the advantage of effectively ensuring the operating range of the cleaning equipment 100 within a single operating cycle. By reducing the supply flow rate of the liquid pump 113 when the cumulative operating time exceeds the fifth duration, the operating time of the cleaning equipment 100 can be extended, avoiding rapid power consumption due to high flow rates, thereby improving the overall working efficiency and reliability of the cleaning equipment 100.

[0111] It should be noted that during a single operating cycle, the second flow rate and the first flow rate of the cleaning equipment 100 are not necessarily the actual flow rates of liquid supplied by the liquid pump 113 to the heater 109. If, during that cycle, the duration for which the heater temperature is lower than the first temperature exceeds the first duration, or if the heater temperature is higher than the third temperature, the flow rate of liquid supplied by the liquid pump 113 to the heater 109 will be adjusted based on either the second flow rate or the first flow rate.

[0112] It should also be noted that in the next start-up cycle, the final flow rate of liquid supplied by the liquid pump 113 to the heater 109, which was determined in the previous start-up cycle, is reset to zero. That is, in the next start-up cycle, the initial flow rate of liquid supplied by the liquid pump 113 to the heater 109 will be re-determined as the second flow rate or the first flow rate based on the cumulative duration.

[0113] Referring again to Figure 2, in this application, the controller 300 can also be configured to: control the heater 109 to start operation if the heater temperature is lower than the second temperature.

[0114] In this application, the second temperature can be in the range of 65-75 degrees Celsius. For example, the second temperature could be 67 degrees Celsius, 68 degrees Celsius, or 69 degrees Celsius. It should be understood that the second temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0115] Based on the technical solution proposed in this application, the cleaning equipment 100 can dynamically adjust the opening and closing of the heater 109 by monitoring the heater temperature in real time. This allows for the stable generation of hot liquid that meets the corresponding temperature requirements within the cleaning equipment 100, ensuring the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode. Specifically, when the heater temperature is lower than a second temperature, controlling the heater 109 to start operation outputs heat to the liquid in the heater 109, thereby increasing the heater temperature (equivalent to increasing the temperature of the liquid in the heater 109). In this way, through this adaptive flow regulation mechanism, the temperature of the liquid flowing out of the cleaning equipment 100 in hot liquid mode can be maintained above the second temperature, thereby improving the cleaning effect of the cleaning equipment 100 on the ground in hot liquid mode, increasing the efficiency and quality of the cleaning tasks performed by the cleaning equipment 100, and thus ensuring the overall reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode.

[0116] Referring again to Figure 2, in this application, the controller 300 can also be configured to: if the heater temperature is greater than a fourth temperature, then control the heater 109 to stop operating, wherein the fourth temperature is greater than the second temperature.

[0117] In this application, the value range of the fourth temperature can be 67-78 degrees Celsius. For example, the fourth temperature can specifically be 69 degrees Celsius, 70 degrees Celsius, or 71 degrees Celsius. It should be understood that the fourth temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0118] In this application, when the heater temperature is high (i.e., above the fourth temperature), by controlling the heater 109 to stop operating, heat output to the liquid in the heater 109 can be stopped, thereby reducing the heater temperature (i.e., equivalent to reducing the temperature of the liquid in the heater 109). In this way, through this adaptive flow regulation mechanism, it can be ensured that the temperature of the liquid flowing out of the cleaning device 100 in hot liquid mode is not too high, thus avoiding safety issues caused by excessively high liquid temperatures. For example, it prevents the liquid in the heater 109 from boiling, and avoids the situation where scalding liquid sprays out due to excessively high internal temperature and pressure of the heater 109, ensuring the safety of the cleaning device 100 in hot liquid mode.

[0119] In general, based on the above scheme, the heater temperature can be controlled between the second and fourth temperatures, thereby maintaining the temperature of the liquid in heater 109 within a reasonable range in hot liquid mode, that is, neither too low nor too high. This control method ensures the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode.

[0120] Referring again to Figure 2, in this application, the controller 300 can also be configured to: if the duration of flowing liquid in the liquid pipeline of the cleaning device 100 meets the sixth duration, then control the heater 109 to start operation; if the duration of no flowing liquid in the liquid pipeline meets the seventh duration, then control the heater 109 to stop operation, wherein the seventh duration is less than the sixth duration.

[0121] In this application, the value range of the sixth duration can be 1.5-2.5 seconds. For example, the sixth duration can specifically be 1.9 seconds, 2 seconds, or 2.1 seconds. It should be understood that the sixth duration can be set according to actual needs, and this application does not impose specific limitations on it.

[0122] In this application, the value range of the seventh duration can be 0.5-1.5 seconds. For example, the seventh duration can specifically be 0.9 seconds, 1 second, or 1.1 seconds. It should be understood that the seventh duration can be set according to actual needs, and this application does not impose specific limitations on it.

[0123] In this application, if there is no continuously flowing liquid in the liquid pipeline of the cleaning equipment 100 within a seventh time period, an alarm can be issued to remind the user to add liquid to the cleaning equipment 100 in a timely manner.

[0124] In this application, on the one hand, by detecting the liquid in the liquid pipeline of the cleaning equipment 100 and delaying the liquid supply, it is possible to effectively prevent the heater 109 from starting when there is no liquid or insufficient liquid in the liquid pipeline, thus avoiding damage to the cleaning equipment components or safety accidents caused by the heater 109 burning out. On the other hand, based on the confirmation that there is liquid flow in the liquid pipeline, by delaying for a sixth time, it is possible to ensure that the liquid flows stably and completely to the heater 109 before controlling the heater 109 to operate, thereby avoiding the situation where the heater 109 burns out due to unstable liquid flow or the liquid in the liquid pipeline not completely flowing to the heater 109. Therefore, this application can improve the operational safety, operational reliability, and service life of the cleaning equipment 100 in hot liquid mode.

[0125] Referring again to Figure 2, in this application, the controller 300 can also be configured to: if the cumulative running time of the cleaning equipment 100 in the same start-up cycle is less than or equal to the eighth duration, then control the heater 109 to operate at a first power; if the cumulative running time of the cleaning equipment 100 in the same start-up cycle is greater than the eighth duration, then control the heater 109 to operate at a second power, the second power being less than the first power.

[0126] In this application, the value range of the eighth duration can be 8-15 minutes. For example, the eighth duration can specifically be 9 minutes, 10 minutes, or 11 minutes. It should be understood that the eighth duration can be set according to actual needs, and this application does not impose specific limitations on it.

[0127] In this application, the first power can be in the range of 270-290 watts. For example, the first power can specifically be 275 watts, 280 watts, or 285 watts. It should be understood that the first power can be set according to actual needs, and this application does not impose any specific limitations on it.

[0128] In this application, the value range of the second power can be 135-155 watts. For example, the second power can specifically be 140 watts, 145 watts, or 150 watts. It should be understood that the second power can be set according to actual needs, and this application does not make a specific limitation in this regard.

[0129] In this application, the second power is specified to be less than the first power. This has the advantage of effectively ensuring the cleaning equipment 100's battery life within a single operating cycle. By reducing the operating power of the heater 109 when the cumulative operating time exceeds eight hours, the usage time of the cleaning equipment 100 can be extended, preventing rapid power consumption due to high heater operating power, thereby improving the overall working efficiency and reliability of the cleaning equipment.

[0130] Referring again to Figure 2, in this application, the controller 300 can also be configured to: control the heater 109 to run if the heater temperature of the cleaning device 100 in standby mode is less than or equal to a fifth temperature; and control the heater 109 to stop running if the heater temperature of the cleaning device 100 in standby mode is greater than or equal to a sixth temperature, wherein the sixth temperature is greater than the fifth temperature.

[0131] In this application, the value range of the fifth temperature can be 40-50 degrees Celsius. For example, the fifth temperature can specifically be 44 degrees Celsius, 45 degrees Celsius, or 46 degrees Celsius. It should be understood that the fifth temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0132] In this application, the value range of the sixth temperature can be 45-55 degrees Celsius. For example, the sixth temperature can specifically be 49 degrees Celsius, 50 degrees Celsius, or 51 degrees Celsius. It should be understood that the sixth temperature can be set according to actual needs, and this application does not impose any specific limitations on it.

[0133] In this application, when the cleaning equipment 100 is in standby mode, by maintaining the heater temperature between the fifth and sixth temperatures, it can more quickly generate hot liquid that meets the temperature requirements when the heater 109 needs to quickly enter the hot liquid mode, thereby improving the overall operating efficiency and reliability of the cleaning equipment 100.

[0134] In this application, it should be noted that in hot liquid mode, the controller 300 can control the cleaning equipment 100 based solely on the control logic for the liquid pump 113, or solely on the control logic for the heater 109.

[0135] In this application, it should also be noted that the controller 300 can simultaneously control the cleaning equipment 100 based on the aforementioned control logic for the liquid pump 113 and the heater 109. This further enhances the reliability of the cleaning equipment 100 in performing cleaning tasks in hot liquid mode. Specifically, the cleaning equipment 100 enables the heater 109 and the liquid pump 113 to work collaboratively, ensuring the stability and continuity of the hot liquid supply. By synchronously adjusting the flow rate of the liquid supplied by the liquid pump 113 and the start / stop state of the heater 109, the generation and delivery rate of the hot liquid can be precisely controlled, thereby optimizing the cleaning effect. Furthermore, the combination of dual control logic allows the overall stability of the cleaning equipment 100 in hot liquid mode to be maintained by adjusting the other control strategy when one control strategy malfunctions, further improving the safety and reliability of the cleaning equipment 100. Overall, the cleaning equipment 100 proposed in this application not only improves the cleaning efficiency of the cleaning equipment 100 in hot liquid mode but also extends its service life, reduces maintenance costs, and provides users with a more efficient and reliable cleaning solution.

[0136] Next, this application will briefly describe the controller 300 in the cleaning equipment 100 with reference to Figure 3.

[0137] As shown in Figure 3, the controller 300 may include at least one memory 304, at least one processor 302, and at least one computer program (computer program instructions) stored in the memory 304 and executable on the processor 302. When the processor 302 executes the computer program, it implements control logic for the various devices in the cleaning equipment as described above (such as the heater 109 and liquid pump 113 shown in Figure 2).

[0138] In Figure 3, the bus architecture (represented by bus 306) includes any number of interconnected buses and bridges, linking various circuits including at least one processor represented by processor 302 and a memory represented by memory 304. Bus 306 can also link various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. Bus interface 305 provides an interface between bus 306 and receiver 301 and transmitter 303. Receiver 301 and transmitter 303 can be the same element, a transceiver, providing a unit for communicating with various other devices over a transmission medium. Processor 302 is responsible for managing bus 306 and general processing, while memory 304 can be used to store data used by processor 302 during operation.

[0139] Based on the same inventive concept, this application also provides a cleaning system, which includes a base station and the cleaning device as described above. The base station is used to place the cleaning device and to charge the cleaning device and replenish it with liquid, such as clean water.

[0140] Based on the same inventive concept, this application also provides a cleaning equipment control method, wherein the cleaning equipment includes a heater and a liquid pump. This cleaning equipment control method can be executed by a device with computational processing capabilities to implement control logic for the liquid pump in the cleaning equipment in a hot liquid mode. It should be noted that for details not disclosed in the embodiments of this application's method, please refer to the above-described embodiments of the cleaning equipment.

[0141] Referring to Figure 4, the cleaning equipment control method includes at least steps 410 to 420:

[0142] Step 410: In hot liquid mode, obtain the heater temperature.

[0143] Step 420: If the duration for which the heater temperature is lower than the first temperature is greater than the first duration, then control the liquid pump to reduce the flow rate of liquid supplied to the heater.

[0144] In this application, the cleaning equipment control method may further include the following steps 421 to 422:

[0145] Step 421: If the duration for which the heater temperature is lower than the first temperature is greater than the first duration, then control the liquid pump to reduce the flow rate of liquid supplied to the heater according to the first flow rate amplitude.

[0146] Step 422: After controlling the liquid pump to reduce the flow rate of liquid supplied to the heater according to the first flow rate amplitude, the timing is restarted to determine whether the duration for which the heater temperature is lower than the first temperature is greater than the first duration.

[0147] In this application, the cleaning equipment control method may further include the following step 430:

[0148] Step 430: If the heater temperature is greater than the third temperature, then control the liquid pump to increase the flow rate of liquid supplied to the heater, wherein the third temperature is greater than the first temperature.

[0149] In this application, the cleaning equipment control method may further include the following steps 431 to 432:

[0150] Step 431: If the heater temperature is greater than the third temperature, then the liquid pump is controlled to increase the flow rate of liquid supplied to the heater according to the second flow rate amplitude, wherein the second flow rate amplitude is positively correlated with the value by which the heater temperature exceeds the third temperature.

[0151] Step 432: After controlling the liquid pump to increase the flow rate of liquid supplied to the heater according to the second flow rate amplitude, re-determine whether the heater temperature is greater than the third temperature.

[0152] In this application, the flow rate of liquid supplied by the liquid pump to the heater is less than or equal to the upper limit of the liquid supply flow rate of the liquid pump.

[0153] In this application, the cleaning equipment control method may further include the following steps 440 to 450:

[0154] Step 440: If the duration of continuous flow of liquid in the liquid pipeline of the cleaning equipment meets the second duration, then control the liquid pump to start operation.

[0155] Step 450: If the duration for which no liquid flows in the liquid pipeline meets the third duration, then control the liquid pump to stop running, wherein the third duration is less than the second duration.

[0156] In this application, the cleaning equipment control method may further include the following step 460:

[0157] Step 460: Within a fourth time period after the cleaning equipment enters the hot liquid mode, stop supplying liquid to the heater and control the heater to stop operating.

[0158] In this application, the cleaning equipment control method may further include the following steps 470 to 480:

[0159] Step 470: If the cumulative operating time of the cleaning equipment in the same start-up cycle is less than or equal to the fifth operating time, then the first flow rate is determined as the initial flow rate of the liquid pump supplying liquid to the heater in hot liquid mode.

[0160] Step 480: If the cumulative runtime of the cleaning equipment in the same start-up cycle is greater than the fifth duration, then the second flow rate is determined as the initial flow rate of the liquid pump supplying liquid to the heater in hot liquid mode, and the second flow rate is less than the first flow rate.
