[0031] Based on the cleaning device proposed in this application, the cleaning device can dynamically adjust the flow rate of the liquid pump to supply liquid to the heater by real-time monitoring of the heater temperature, so as to stably generate hot liquid that meets the corresponding temperature requirements in the cleaning device, and ensure the reliability of performing the cleaning task in the hot liquid mode. Specifically, when the temperature of the heater is lower than the first temperature for a long time, by reducing the flow rate of the liquid supplied to the heater, it can be ensured that the unit volume of liquid absorbs more heat, thereby increasing the heater temperature (i.e., increasing the temperature of the liquid in the heater). Through this adaptive flow regulation mechanism, it can be ensured that the temperature of the liquid flowing out of the cleaning device in the hot liquid mode will not be too low, thereby improving the cleaning effect, improving the efficiency and quality of the cleaning task, and ensuring the reliability of the cleaning device in performing the cleaning task in the hot liquid mode.

[0032] In addition, the cleaning equipment can also monitor the temperature of the heater in real time and dynamically adjust the opening and closing of the heater, so as to stably generate hot liquid that meets the corresponding temperature requirements and ensure reliability in the hot liquid mode. Specifically, when the temperature of the heater is lower than the second temperature, by controlling the heater to start running, heat can be output to the liquid in the heater, thereby increasing the heater temperature (i.e., increasing the temperature of the liquid in the heater). This adaptive heater start-stop adjustment mechanism can ensure that the temperature of the liquid flowing out of the cleaning equipment in the hot liquid mode is dynamically maintained above the second temperature, thereby improving the efficiency and quality of the cleaning equipment in performing cleaning tasks and ensuring the reliability of the cleaning equipment in performing cleaning tasks in the hot liquid mode.

[0033] In general, the cleaning device proposed in this application can realize the coordinated work of the heater and the liquid pump to ensure 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 and stop status of the heater, the amount of hot liquid generated and the delivery rate can be accurately controlled, thereby optimizing the cleaning effect. In addition, combined with the dual control logic, when an abnormality occurs in one control strategy, the overall stability of the cleaning device in the hot liquid mode can be maintained by adjusting another control strategy, further improving the reliability of the cleaning device.

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0057] The block diagrams shown in the accompanying drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, or in at least one hardware module or integrated circuit, or in different networks and / or processor devices and / or microcontroller devices. It should also be noted that in the accompanying drawings, in order to ensure the simplicity of the drawings, some devices in the drawings that do not affect the explanation of the technical solution of the present application are adaptively omitted.

[0058] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0059] 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 understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0060] In order to make those skilled in the art better understand the present application, firstly, Figure 1 The cleaning equipment and system architecture involved in this application are briefly described.

[0061] like Figure 1 , shows a system architecture of a cleaning device in an embodiment, in which the system architecture includes a liquid tank 101, a liquid detection device 102 (e.g., a flow meter, a liquid level meter), 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 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 a cleaning component 116 (e.g., a cleaning roller brush, a mop).

[0062] Among them, the liquid tank 101 is used to store liquid, and the liquid can be clean water or other liquids that can clean the ground or cleaning parts, and this application does not make specific restrictions on this. The liquid detection device 102 can be used to detect the liquid flow in the liquid pipeline, and can be used to determine whether there is flowing liquid in the liquid pipeline. The heater liquid pump 107 is used to pump a set flow of liquid into the heater 109, so that the heater 109 heats the liquid to generate steam, and flows to the steam nozzle 112 through the first reversing valve 111, and finally sprays the steam to the ground. The liquid pump 113 can pump a larger set flow of liquid into the heater 109 through the second reversing valve 114, so that the heater 109 heats the liquid to generate a hot liquid with a higher temperature, and the generated hot liquid flows to the cleaning part 116 through the first reversing valve 111, so as to clean the ground or clean the cleaning parts with hot liquid. The liquid pump 113 can also directly pump a lower temperature liquid (can be a room temperature liquid) to the cleaning part 116 through the second reversing valve 114 to clean the ground or clean the cleaning parts.

[0063] 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 device. In the cleaning device of this embodiment, the liquid flow path may include flow path A, flow path B, and flow path C, which are used for the cleaning device to perform cleaning tasks in cold liquid mode, hot liquid mode, and steam mode, respectively. In addition, the cleaning device also includes a flow path D, in which the detergent pump 105 pumps the detergent in the detergent tank 104 into the second three-way valve 106 to deliver the detergent to the entire liquid pipeline.

[0064] Specifically, in the cold liquid mode, the second reversing valve 114 is in a closed state, and the liquid flows 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 member 116 in sequence. Since the liquid is not heated by the heater 109, the liquid flowing to the cleaning member 116 is in a low-temperature liquid state (such as a room temperature liquid state).

[0065] In the hot liquid mode, the first reversing valve 111 and the second reversing valve 114 are both in the open state, and the liquid flows 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 110, the first reversing valve 111, the third three-way valve 115, and the cleaning element 116 in sequence. Since the liquid is heated by the heater 109, the liquid flowing to the cleaning element 116 is in a high-temperature liquid state, which can enhance the cleaning effect on the floor or the cleaning element.

[0066] In the steam mode, the first reversing valve 111 is in a closed state, and the liquid flows 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 110, the first reversing valve 111, and the steam port 112 in sequence. Since the liquid passes through the heater liquid pump 107 and flows through the heater 109 for heating, the liquid flowing to the steam port 112 is in a high-temperature gaseous state, which can enhance the cleaning effect on the floor.

[0067] In practical applications, when the cleaning device cleans the floor, the liquid pump provides liquid to the cleaning member, which can wet the cleaning member, thereby facilitating the cleaning of stains on the floor. Furthermore, when the cleaning device with a hot liquid mode cleans the floor, the hot liquid flows out to the cleaning member, which can soften the solid stains on the floor and facilitate the cleaning of the solid stains on the one hand, and kill the microorganisms on the floor at high temperature on the other hand. In this way, the cleaning effect of the cleaning device on the floor can be greatly improved. However, how to stably generate hot liquid that meets certain temperature requirements in the cleaning device to ensure the reliability of the cleaning device in performing cleaning tasks in the hot liquid mode is crucial. In this case, the present application proposes some embodiments of cleaning devices and control methods thereof to ensure the reliability of the cleaning device in performing cleaning tasks in the hot liquid mode.

[0068] Next, the implementation details of the technical solution of the embodiment of the present application will be elaborated in detail.

[0069] Before the description, it should be noted that, in order to enable those skilled in the art to better understand the present application, the present application will list 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 of the specification, the present application will not specifically explain this in the subsequent description. In addition, the specific values ​​of the control parameters in the embodiments are merely exemplary. In actual applications, the control parameters in the embodiments may also be other values ​​according to actual conditions.

[0070] Reference Figure 2 The cleaning device 100 proposed in the present application may include a heater 109 , a liquid pump 113 , a temperature detection device 117 , and a controller 300 .

[0071] Among them, the heater 109 is configured to heat the liquid; the liquid pump 113 is connected to the heater 109, and the liquid pump 113 is configured to supply liquid to the heater 109; the temperature detection device 117 is provided on the heater 109, and the temperature detection device 117 is configured to collect the temperature of the heater; the controller 300 is communicatively connected with the heater 109, the liquid pump 113, and the temperature detection device 117.

[0072] Continue to refer to Figure 2 In the present application, the controller 300 may be configured as follows: in the hot liquid mode, obtaining the heater temperature collected by the temperature detection device 117; if the heater temperature is less than the first temperature for a duration greater than the first duration, controlling the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109.

[0073] In the present application, the temperature detection device 117 can be a negative temperature coefficient thermistor (NTC), a thermocouple (Thermocouple), an infrared temperature sensor (ITS), a semiconductor temperature sensor (STS), or a bimetallic temperature sensor (BTS), and the present application does not make any specific limitations on this.

[0074] In the present application, the value range of the first temperature may be 55-65 degrees, for example, the first temperature may be 59 degrees, 60 degrees, or 61 degrees. It should be understood that the first temperature may be set according to actual needs, and the present application does not specifically limit this.

[0075] In the present application, the value range of the first duration may be 15-25 seconds, for example, the first duration may be 19 seconds, 20 seconds, or 21 seconds. It should be understood that the first duration may be set according to actual needs, and the present application does not make any specific limitation on this.

[0076] Based on the technical solution proposed in this application, the cleaning device 100 can dynamically adjust the flow rate of the liquid pump 113 to the heater 109 by monitoring the heater temperature in real time, so that the hot liquid that meets the corresponding temperature requirements can be stably generated in the cleaning device 100, ensuring the reliability of the cleaning device 100 in performing the cleaning task in the hot liquid mode. Specifically, when the temperature of the heater is lower than the first temperature for a long time, by reducing the flow rate of the liquid supplied to the heater 109, it can be ensured that the unit volume of liquid can absorb more heat, so that the heater temperature can be increased (that is, equivalent to increasing 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 the hot liquid mode will not be too low, so that the cleaning effect of the cleaning device 100 on the ground in the hot liquid mode can be improved, the efficiency and quality of the cleaning device 100 in performing the cleaning task can be improved, and the reliability of the cleaning device 100 in performing the cleaning task in the hot liquid mode can be ensured as a whole.

[0077] Furthermore, in the present application, the controller 300 can also be configured as follows: if the duration of the heater temperature being lower than the first temperature is greater than the first duration, the liquid pump 113 is controlled to reduce the flow rate of liquid supplied to the heater 109 according to the first flow amplitude ml / min; after the liquid pump 113 is controlled to reduce the flow rate of liquid supplied to the heater 109 according to the first flow amplitude ml / min, the timing is restarted to determine whether the duration of the heater temperature being lower than the first temperature is greater than the first duration.

[0078] In the present application, the value range of the first flow amplitude may be 2-4 ml / min, for example, the first flow amplitude may be 2.9 ml / min, 3 ml / min, or 3.1 ml / min. It should be understood that the first flow amplitude may be set according to actual needs, and the present application does not make any specific limitation on this.

[0079] In the present application, it can be understood that after retiming, if the duration that the heater temperature is less than the first temperature is still greater than the first duration, the liquid pump 113 can be controlled again according to the first flow amplitude to reduce the flow rate of liquid supplied to the heater 109, and this cycle is repeated until the condition that the heater temperature is less than the first temperature for more than the first duration is no longer met.

[0080] In order to enable those skilled in the art to better understand the present application, a specific embodiment is described below.

[0081] In a specific embodiment, the liquid pump 113 currently supplies liquid to the heater 109 at a flow rate of 60 ml / min, the first temperature is 60 degrees, the first time length may be 20 seconds, and the first flow amplitude may be 3 ml / min.

[0082] In this embodiment, when the flow rate of the liquid pump 113 supplying the liquid to the heater 109 is controlled to be 60 ml / min, if the duration of the heater temperature being 55 degrees (less than 60 degrees) is greater than 20 seconds, the flow rate of the liquid pump 113 supplying the liquid to the heater 109 is controlled to be 60 ml / min-3 ml / min=57 ml / min, and the timing is restarted;

[0083] Under the condition that the flow rate of the liquid pump 113 supplying the liquid to the heater 109 is controlled to be 57 ml / min, if the duration of the heater temperature being 58 degrees (less than 60 degrees) is greater than 20 seconds, the flow rate of the liquid pump 113 supplying the liquid to the heater 109 can be controlled to be 57 ml / min-3 ml / min=54 ml / min, and the timing is reset;

[0084] When the liquid pump 113 is controlled to supply liquid to the heater 109 at a flow rate of 54 ml / min, if the duration of the heater temperature being less than 60 degrees is only 10 seconds (i.e., at the 11th second, the heater temperature exceeds 60 degrees), it indicates that the condition that the heater temperature is less than the first temperature for a duration greater than the first time period is not currently met, and therefore there is no need to continue controlling the liquid pump 113 to reduce the flow rate of liquid supplied to the heater 109.

[0085] It can be understood that, based on the control logic of the above embodiment, the heater temperature (ie, the temperature of the heater 109 collected by the temperature detection device 117) can be dynamically stabilized at 60 degrees or above.

[0086] In the present application, when the heater temperature is in a relatively low state (i.e., the heater temperature is below the first temperature for a long time), by controlling the liquid pump 113 to gradually reduce the flow rate of liquid supplied to the heater 109, the amount of heat absorbed by a unit volume of liquid per unit time can be increased, thereby increasing the increase in the liquid temperature per unit time, and ultimately increasing the temperature of the liquid in the heater 109, which is specifically manifested in the heater temperature being stabilized at or above the first temperature. In this way, the liquid temperature in the heater 109 can meet the requirements for the liquid temperature in the hot liquid mode, thereby achieving stable generation of hot liquid in the cleaning device 100, improving the cleaning effect of the cleaning device 100 on the ground in the hot liquid mode, improving the efficiency and quality of the cleaning device 100 in performing cleaning tasks, and ensuring the reliability of the cleaning device 100 in performing cleaning tasks in the hot liquid mode.

[0087] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured to control the liquid pump 113 to increase the flow rate of the liquid supplied to the heater 109 if the heater temperature is greater than a third temperature, and the third temperature is greater than the first temperature.

[0088] In the present application, the value range of the third temperature may be 65-75 degrees, for example, the third temperature may be 67 degrees, 68 degrees, or 69 degrees. It should be understood that the third temperature may be set according to actual needs, and the present application does not make any specific limitation on this.

[0089] In the present application, when the temperature of the heater is at a higher state (i.e., higher than the third temperature), by increasing the flow rate of the liquid supplied to the heater 109, the heat absorbed by the unit volume of the liquid can be reduced, thereby reducing the temperature of the heater (i.e., reducing the temperature of the liquid in the heater 109). Through this adaptive flow regulation mechanism, it can be ensured that the temperature of the liquid flowing out of the cleaning device 100 in the hot liquid mode is not too high, thereby avoiding safety problems caused by excessively high liquid temperature, such as preventing the liquid in the heater 109 from boiling, and avoiding the situation where the boiling liquid is sprayed out due to the excessively high temperature and pressure inside the heater 109. In this way, the safety of the cleaning device 100 in the hot liquid mode can be guaranteed.

[0090] In general, based on the above scheme, the heater temperature can be controlled between the first temperature and the third temperature, so that the temperature of the liquid in the heater 109 in the hot liquid mode is kept within a reasonable range, that is, neither too low nor too high. This control method ensures the reliability of the cleaning device 100 in performing cleaning tasks in the hot liquid mode.

[0091] Furthermore, in the present application, the controller 300 can also be configured as follows: if the heater temperature is greater than the third temperature, then controlling the liquid pump 113 to increase the flow rate of liquid supplied to the heater 109 according to the second flow amplitude milliliters / minute, and the second flow amplitude is positively correlated with the excess value of the heater temperature over 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 amplitude milliliters / minute, re-determining whether the heater temperature is greater than the third temperature.

[0092] In the present application, for every 1 degree that the heater temperature exceeds the third temperature, the value range of the second flow amplitude increase value may be 2-4 ml / min. For example, the increase value may be 2.9 ml / min, 3 ml / min, or 3.1 ml / min. It should be understood that the increase value of the second flow amplitude may be set according to actual needs, and the present application does not specifically limit this.

[0093] In the present application, it can be understood that if the heater temperature exceeds the third temperature by a greater value, the second flow amplitude will be greater.

[0094] In order to enable those skilled in the art to better understand the present application, a specific embodiment is described below.

[0095] In a specific embodiment, the liquid pump 113 currently supplies liquid to the heater 109 at a flow rate of 60 ml / min, the third temperature is 68 degrees, and the increase value of the second flow amplitude may be 3 ml / min.

[0096] In this embodiment, when the flow rate of the liquid pump 113 supplying the liquid to the heater 109 is controlled to be 60 ml / min, if the temperature of the heater is 70 degrees (the excess value relative to 68 degrees is 2 degrees), the flow rate of the liquid pump 113 supplying the liquid to the heater 109 can be controlled to be 60 ml / min+3 ml / min×2=66 ml / min;

[0097] In this embodiment, when the flow rate of the liquid pump 113 supplying the liquid to the heater 109 is controlled to be 60 ml / min, if the temperature of the heater is 69 degrees (the excess value relative to 68 degrees is 1 degree), the flow rate of the liquid pump 113 supplying the liquid to the heater 109 can be controlled to be 60 ml / min+3 ml / min=63 ml / min;

[0098] It can be understood that, based on the control logic of the above embodiment, the heater temperature (ie, the temperature of the heater 109 collected by the temperature detection device 117) can be dynamically stabilized at 68 degrees or below.

[0099] In the present application, according to the extent to which the heater temperature exceeds the third temperature, the corresponding flow amplitude is increased based on the flow rate of the liquid currently supplied to the heater 109 by the liquid pump 113. This can reduce the amount of heat absorbed by a unit volume of liquid per unit time, thereby slowing down the rise in the liquid temperature, and ultimately stabilizing the temperature of the liquid in the heater 109 at or below the third temperature. In this way, the heater temperature can be controlled within a range that is neither too low nor too high, ensuring that the liquid temperature in the heater 109 meets the requirements in the hot liquid mode. This process achieves the effect of stably generating hot liquid in the cleaning device 100, which not only improves the cleaning effect of the cleaning device 100 on the ground in the hot liquid mode, but also ensures the safety of its operation, thereby improving the efficiency and quality of the cleaning device 100 in performing cleaning tasks, and ensuring its reliability in the hot liquid mode.

[0100] In the present application, the controller 300 may also be configured to: control the flow rate of the 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 .

[0101] In the present 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 the present application does not make any specific limitation on this.

[0102] In the present application, by controlling the flow rate of the liquid pump 113 to supply the liquid 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, on the one hand, it is possible to avoid the liquid pump 113 from increasing the flow rate of the liquid supplied to the heater 109 without limit, and to prevent the excessive flow rate of the supplied liquid from affecting the normal operation of the cleaning device 100. On the other hand, it is possible to avoid the overload operation of the liquid pump 113, reduce the risk of failure of the liquid pump 113, and thus improve the stability and reliability of the cleaning device 100 as a whole.

[0103] Continue to refer to Figure 2 In the present application, the cleaning device 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 device 100 .

[0104] Furthermore, the controller 300 can also be configured as follows: if the duration of the presence of flowing liquid in the liquid pipeline of the cleaning equipment 100 satisfies a second time length, the liquid pump 113 is controlled to start running; if the duration of the absence of flowing liquid in the liquid pipeline satisfies a third time length, the liquid pump 113 is controlled to stop running, and the third time length is less than the second time length.

[0105] In the present application, the liquid detection device 102 may be a flow meter or a liquid level meter, and the present application does not make any specific limitation on this.

[0106] In the present application, the value interval of the second duration may be 1.5-2.5 seconds, for example, the second duration may be 2 seconds or 2.2 seconds. The value interval of the third duration may be 0.5-1.5 seconds, for example, the third duration may be 1 second or 1.2 seconds. It should be understood that the second duration and the third duration may be set according to actual needs, and the present application does not specifically limit this.

[0107] In the present application, if there is no continuous flowing liquid in the liquid pipeline of the cleaning device 100 within the third time period, an alarm may be issued to remind the user to add liquid to the cleaning device 100 in time.

[0108] In the present application, on the one hand, after the cleaning device 100 enters the hot liquid mode, by detecting the liquid in the liquid pipeline of the cleaning device 100 and delaying the control of the liquid supply, it is possible to effectively prevent the liquid pump 113 from being started when there is no liquid or insufficient liquid in the liquid pipeline, which triggers the start of the heater 109 and avoids damage to the components or safety accidents in the cleaning device 100 caused by the dry burning of the heater 109. On the other hand, on the basis of confirming that there is liquid flow in the liquid pipeline, by delaying the second time length and then controlling the liquid pump 113 to supply liquid to the heater 109, it is possible to ensure that the liquid flows stably to the heater 109, thereby avoiding the situation where the heater 109 is dry burned due to unstable liquid flow or the liquid in the liquid pipeline has not completely flowed to the heater 109. Therefore, the present application can improve the operational safety, operational reliability and service life of the cleaning device 100 in the hot liquid mode.

[0109] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured to: within a fourth time period after the cleaning device 100 enters the hot liquid mode, stop supplying liquid to the heater 109 and control the heater 109 to stop running.

[0110] In the present application, the value range of the fourth duration may be 2-13 seconds, for example, the fourth duration may be 5 seconds, 6 seconds, or 7 seconds. It should be understood that the fourth duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0111] In the present application, the cleaning device 100 may include a mode trigger (not shown in the figure), which may at least be used for a user to trigger the cleaning device 100 to enter a steam mode, a hot liquid mode, or a cold liquid mode.

[0112] In the present application, the mode trigger may include a button or voice control device on the cleaning device 100, or an APP installed in a mobile phone or computer for controlling the cleaning device. Specifically, the present application does not make too many restrictions. It can be understood that through the mode trigger, the user can conveniently trigger the steam mode, hot liquid mode, or cold liquid mode according to actual needs, thereby realizing convenient switching of the working mode of the cleaning device 100.

[0113] In the present application, when the cleaning device 100 is triggered to enter the steam mode, or the hot liquid mode, or the cold liquid mode, the controller 300 can control the cleaning device 100 to switch to the corresponding working mode, and send a corresponding prompt message to the user within a certain period of time. For example, if the user triggers the cleaning device 100 to enter the hot liquid mode, the cleaning device 100 will switch its working mode to the hot liquid mode, and broadcast a voice message of "switched to the hot liquid mode" through voice broadcast, or display a text message of "switched to the hot liquid mode" in the user interface. In this way, the user can intuitively understand what working mode the cleaning device 100 is currently in.

[0114] In the present application, since the cleaning device 100 shares the heater 109 in the steam mode and the hot liquid mode, and the heater 109 adopts over-current heating in the hot liquid mode, the liquid will fill the heater. Therefore, when the cleaning device 100 is triggered to enter the hot liquid mode, by controlling the liquid pump 113 to stop supplying liquid to the heater 109 within the fourth time length, and controlling the heater 109 to stop running, the user can clearly understand the actual working mode of the cleaning device 100 during this period. If the actual working mode is the hot liquid mode, and the user wants to switch to the steam mode, the user can actively switch after confirming the current mode. This can avoid the situation where the heater 109 is filled with liquid due to the user's ambiguity about the working mode of the cleaning device 100 or the wrong triggering of the hot liquid mode.

[0115] Based on the technical solution proposed in the present application, when the cleaning device 100 enters the hot liquid mode, by stopping the liquid supply of the liquid pump 113 within the fourth time period and controlling the heater 109 to stop running, the user can realize that the cleaning device 100 is in the hot liquid mode according to the prompt information within the fourth time period, and further operate to 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 device in the steam mode will not be extended, thereby improving the efficiency of the cleaning device in performing cleaning tasks in the steam mode and enhancing the user experience.

[0116] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the cumulative operating time of the cleaning device 100 in the same power-on cycle is less than or equal to the fifth time period, the first flow rate is determined as the initial flow rate of the liquid pump 113 supplying liquid to the heater 109 in the hot liquid mode; if the cumulative operating time of the cleaning device 100 in the same power-on cycle is greater than the fifth time period, the second flow rate is determined as the initial flow rate of the liquid pump 113 supplying liquid to the heater 109 in the hot liquid mode, and the second flow rate is less than the first flow rate.

[0117] In some embodiments, the power-on cycle may refer to a 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 (ie, the cleaning device 100 is not powered off during the entire process).

[0118] In the present application, the value interval of the fifth duration may be 8-15 minutes, for example, the fifth duration may be 9 minutes, 10 minutes, or 11 minutes. It should be understood that the fifth duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0119] In the present application, the value range of the first flow rate can be 55-65 ml / min. For example, the first flow rate can 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 the present application does not make specific limitations on this.

[0120] In the present application, the value range of the second flow rate can be 35-45 ml / min. For example, the second flow rate can 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 the present application does not make specific limitations on this.

[0121] In the present application, the second flow rate is limited to be less than the first flow rate, and its advantage is that the endurance of the cleaning device 100 within a startup cycle can be effectively guaranteed. By reducing the supply flow rate of the liquid pump 113 when the cumulative operating time exceeds the fifth time period, the use time of the cleaning device 100 can be extended, and the rapid consumption of electricity due to high flow rate can be avoided, thereby improving the overall working efficiency and reliability of the cleaning device 100.

[0122] It should be noted that, during a startup cycle of the cleaning device 100, the second flow rate and the first flow rate are not necessarily the actual flow rates of the liquid pump 113 supplying the liquid to the heater 109. If, during the cycle, the duration of the heater temperature being lower than the first temperature is longer than the first duration, or if the heater temperature is higher than the third temperature, the flow rate of the liquid pump 113 supplying the liquid to the heater 109 will be adjusted based on the second flow rate or the first flow rate.

[0123] It should be further explained that, in the next power-on cycle of the cleaning device 100, the final flow rate of liquid supplied by the liquid pump 113 to the heater 109 determined in the previous power-on cycle is reset to zero, that is, in the next power-on 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 accumulated time.

[0124] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured to: if the heater temperature is lower than the second temperature, control the heater 109 to start running.

[0125] In the present application, the second temperature may be in the range of 65-75 degrees, for example, the second temperature may be 67 degrees, 68 degrees, or 69 degrees. It should be understood that the second temperature may be set according to actual needs, and the present application does not specifically limit this.

[0126] Based on the technical solution proposed in this application, the cleaning device 100 can dynamically adjust the opening and closing of the heater 109 by real-time monitoring of the heater temperature, so that the hot liquid that meets the corresponding temperature requirements can be stably generated in the cleaning device 100, ensuring the reliability of the cleaning device 100 in performing the cleaning task in the hot liquid mode. Specifically, when the heater temperature is less than the second temperature, by controlling the heater 109 to start running, heat can be output to the liquid in the heater 109, so that the heater temperature can be increased (i.e., equivalent to increasing 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 the hot liquid mode is maintained above the second temperature, so that the cleaning effect of the cleaning device 100 on the ground in the hot liquid mode can be improved, and the efficiency and quality of the cleaning device 100 in performing the cleaning task can be improved, thereby ensuring the reliability of the cleaning device 100 in performing the cleaning task in the hot liquid mode as a whole.

[0127] Continue to refer to Figure 2 In the present application, the controller 300 may also be configured to control the heater 109 to stop running if the heater temperature is greater than a fourth temperature, and the fourth temperature is greater than the second temperature.

[0128] In the present application, the fourth temperature may be in the range of 67-78 degrees, for example, the fourth temperature may be 69 degrees, 70 degrees, or 71 degrees. It should be understood that the fourth temperature may be set according to actual needs, and the present application does not specifically limit this.

[0129] In the present application, when the temperature of the heater is at a high state (i.e., higher than the fourth temperature), the heater 109 can be controlled to stop running, so that the heat output to the liquid in the heater 109 can be stopped, thereby lowering the temperature of the heater (i.e., equivalent to lowering 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 the hot liquid mode will not be too high, thereby avoiding safety problems caused by excessively high liquid temperature, such as preventing the liquid in the heater 109 from boiling, avoiding the situation where boiling liquid is sprayed out due to excessively high internal temperature and pressure of the heater 109, and ensuring the safety of the cleaning device 100 in the hot liquid mode.

[0130] In general, based on the above scheme, the heater temperature can be controlled between the second temperature and the fourth temperature, so that the temperature of the liquid in the heater 109 in the hot liquid mode is kept within a reasonable range, that is, neither too low nor too high. This control method ensures the reliability of the cleaning device 100 in performing cleaning tasks in the hot liquid mode.

[0131] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the duration of the presence of flowing liquid in the liquid pipeline of the cleaning device 100 satisfies a sixth time length, the heater 109 is controlled to start running; if the duration of the absence of flowing liquid in the liquid pipeline satisfies a seventh time length, the heater 109 is controlled to stop running, and the seventh time length is less than the sixth time length.

[0132] In the present application, the sixth duration may be set in the range of 1.5-2.5 seconds. For example, the sixth duration may be 1.9 seconds, 2 seconds, or 2.1 seconds. It should be understood that the sixth duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0133] In the present application, the seventh duration may be set in the range of 0.5-1.5 seconds. For example, the seventh duration may be 0.9 seconds, 1 second, or 1.1 seconds. It should be understood that the seventh duration may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0134] In the present application, if there is no continuous flowing liquid in the liquid pipeline of the cleaning device 100 within the seventh time period, an alarm may be issued to remind the user to add liquid to the cleaning device 100 in time.

[0135] In the present application, on the one hand, by detecting the liquid in the liquid pipeline of the cleaning device 100 and delaying the control of the liquid supply, it is possible to effectively prevent the heater 109 from being started when there is no liquid or insufficient liquid in the liquid pipeline, thereby avoiding damage to the cleaning equipment components or safety accidents caused by the dry burning of the heater 109. On the other hand, on the basis of confirming that there is liquid flow in the liquid pipeline, by delaying the sixth time period, it is possible to ensure that the liquid flows stably and completely flows to the heater 109 and then control the operation of the heater 109, thereby avoiding the situation where the heater 109 is dry burned due to unstable liquid flow or the liquid in the liquid pipeline not completely flowing to the heater 109. Therefore, the present application can improve the operational safety, operational reliability and service life of the cleaning device 100 in the hot liquid mode.

[0136] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the cumulative operating time of the cleaning device 100 in the same power-on cycle is less than or equal to the eighth time period, the heater 109 is controlled to operate at a first power; if the cumulative operating time of the cleaning device 100 in the same power-on cycle is greater than the eighth time period, the heater 109 is controlled to operate at a second power, and the second power is less than the first power.

[0137] In the present application, the eighth duration may be set between 8 and 15 minutes. For example, the eighth duration may be set between 9 minutes, 10 minutes, or 11 minutes. It should be understood that the eighth duration may be set according to actual needs, and the present application does not specifically limit this.

[0138] In the present application, the value range of the first power may be 270-290 W, for example, the first power may be 275 W, 280 W, or 285 W. It should be understood that the first power may be set according to actual needs, and the present application does not specifically limit this.

[0139] In the present application, the second power may be in a value range of 135-155 W, for example, the second power may be 140 W, 145 W, or 150 W. It should be understood that the second power may be set according to actual needs, and the present application does not specifically limit this.

[0140] In the present application, the second power is limited to be less than the first power, and its advantage is that the endurance of the cleaning device 100 within a startup cycle can be effectively guaranteed. By reducing the operating power of the heater 109 when the cumulative operating time exceeds the eighth time, the use time of the cleaning device 100 can be extended, and the rapid consumption of electricity due to the high operating power of the heater can be avoided, thereby improving the overall working efficiency and reliability of the cleaning device.

[0141] Continue to refer to Figure 2 In the present application, the controller 300 can also be configured as follows: if the heater temperature of the cleaning device 100 in the standby state is less than or equal to the fifth temperature, the heater 109 is controlled to run; if the heater temperature of the cleaning device 100 in the standby state is greater than or equal to the sixth temperature, the heater 109 is controlled to stop running, and the sixth temperature is greater than the fifth temperature.

[0142] In the present application, the fifth temperature may be in the range of 40-50 degrees, for example, the fifth temperature may be 44 degrees, 45 degrees, or 46 degrees. It should be understood that the fifth temperature may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0143] In the present application, the sixth temperature may be in the range of 45-55 degrees, for example, the sixth temperature may be 49 degrees, 50 degrees, or 51 degrees. It should be understood that the sixth temperature may be set according to actual needs, and the present application does not make any specific limitation thereto.

[0144] In the present application, when the cleaning device 100 is in standby mode, by maintaining the heater temperature between the fifth temperature and the sixth temperature, when the heater 109 needs to quickly enter the hot liquid mode, hot liquid that meets the temperature requirements can be generated more quickly, thereby improving the overall operating efficiency and reliability of the cleaning device 100.

[0145] In the present application, it should be noted that, in the hot liquid mode, the controller 300 can control the cleaning device 100 only based on the above control logic for the liquid pump 113 , or can control the cleaning device 100 only based on the above control logic for the heater 109 .

[0146] In the present application, it should also be noted that the controller 300 can also control the cleaning device 100 based on the above-mentioned control logic for the liquid pump 113 and the heater 109 at the same time. In this way, the reliability of the cleaning device 100 in performing cleaning tasks in the hot liquid mode can be further enhanced. Specifically, the cleaning device 100 can realize the coordinated work of the heater 109 and the liquid pump 113 to ensure the stability and continuity of the hot liquid supply. By synchronously adjusting the flow rate of the liquid pump 113 supplying liquid and the start and stop state of the heater 109, the amount of hot liquid produced and the delivery rate can be accurately controlled, thereby optimizing the cleaning effect. In addition, in combination with the dual control logic, when a certain control strategy is abnormal, the overall stability of the cleaning device 100 in the hot liquid mode can be maintained by adjusting another control strategy, further improving the safety and reliability of the cleaning device 100. Overall, the cleaning device 100 proposed in this application not only improves the cleaning efficiency of the cleaning device 100 in the hot liquid mode, but also extends the service life of the cleaning device 100, reduces maintenance costs, and provides users with a more efficient and reliable cleaning solution.

[0147] Next, this application will combine Figure 3 , a brief description is given of the controller 300 in the cleaning device 100.

[0148] like Figure 3 As shown, the controller 300 may include at least one memory 304, at least one processor 302, and at least one computer program (computer program instruction) stored in the memory 304 and executable on the processor 302. When the processor 302 executes the computer program, the components (such as Figure 2 The control logic of the heater 109 and liquid pump 113) shown.

[0149] Among them, Figure 3 In the embodiment of the present invention, a bus architecture (represented by bus 306) is provided, which may include any number of interconnected buses and bridges, and bus 306 links various circuits including at least one processor represented by processor 302 and a memory represented by memory 304. Bus 306 may also link various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. Bus interface 305 provides an interface between bus 306 and receiver 301 and transmitter 303. Receiver 301 and transmitter 303 may be the same element, namely 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 may be used to store data used by processor 302 when performing operations.

[0150] Based on the same inventive concept, an embodiment of the present application also provides a cleaning system, which includes a base station and the cleaning device as described above, wherein the base station is used to place the cleaning device, charge the cleaning device, and replenish liquid, such as clean water.

[0151] Based on the same inventive concept, the embodiment of the present application also provides a cleaning device control method, wherein the cleaning device includes a heater and a liquid pump. The cleaning device control method can be executed by a device with a computing and processing function to implement the control logic of the liquid pump in the cleaning device in the hot liquid mode. It should be noted that for details not disclosed in the embodiment of the method of the present application, please refer to the embodiment of the cleaning device described above in the present application.

[0152] Reference Figure 4 As shown, the cleaning equipment control method at least includes steps 410 to 420:

[0153] Step 410, in hot liquid mode, obtain the heater temperature.

[0154] In step 420 , if the duration of the temperature of the heater being lower than the first temperature is longer than the first duration, the liquid pump is controlled to reduce the flow rate of the liquid supplied to the heater.

[0155] In the present application, the cleaning equipment control method may further include the following steps 421 to 422:

[0156] Step 421: If the duration of the time during which the temperature of the heater is lower than the first temperature is greater than the first time, the liquid pump is controlled to reduce the flow rate of the liquid supplied to the heater according to the first flow rate amplitude.

[0157] Step 422, after controlling the liquid pump to reduce the flow rate of the liquid supplied to the heater according to the first flow amplitude, re-timing to determine whether the duration of the heater temperature being less than the first temperature is greater than the first duration.

[0158] In the present application, the cleaning equipment control method may further include the following step 430:

[0159] Step 430 : If the temperature of the heater is greater than a third temperature, controlling the liquid pump to increase the flow rate of the liquid supplied to the heater, and the third temperature is greater than the first temperature.

[0160] In the present application, the cleaning equipment control method may further include the following steps 431 to 432:

[0161] Step 431: If the heater temperature is greater than the third temperature, control the liquid pump to increase the flow rate of liquid supplied to the heater according to a second flow rate amplitude, and the second flow rate amplitude is positively correlated with the excess value of the heater temperature over the third temperature.

[0162] Step 432: after controlling the liquid pump to increase the flow rate of the liquid supplied to the heater according to the second flow rate amplitude, re-determine whether the temperature of the heater is greater than the third temperature.

[0163] In the present 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.

[0164] In the present application, the cleaning equipment control method may further include the following steps 440 to 450:

[0165] Step 440: If the duration of the flowing liquid in the liquid pipeline of the cleaning device satisfies a second duration, the liquid pump is controlled to start running.
