Detailed implementation manners

[0022] Here, the technical solutions in the embodiments (or "implementation manners") of this application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0023] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and motion conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of this application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0024] With the development of technology and social progress, more and more families begin to use cleaning devices such as fabric cleaning machines, carpet cleaning machines, or floor washing machines to improve the efficiency and quality of household cleaning. Currently, there are many brands of cleaning devices available for consumers to choose from in the market. How to gain the favor of consumers and enhance product competitiveness is an issue that cleaning device manufacturers pay more and more attention to.

[0025] Taking a floor washer as an example, a floor washer is a common cleaning device. Users can move the floor washer on the ground by hand and use the floor brush of the floor washer to clean the dirt on the ground. Usually, there are different degrees of dirt on the ground, including easily cleaned light dirt such as dust, hair or sweat stains, and stubborn dirt such as oil stains, water scale or mold that is more difficult to clean. Therefore, in the related art, a floor washer usually has an output component (such as a nozzle or a water spraying plate, etc.) for outputting cleaning media such as clean water, cleaning liquid or foam, so that the floor washer can provide and output a variety of cleaning media to deal with cleaning dirt of different degrees.

[0026] However, in the related art, the nozzle of the floor washer for outputting foam is often blocked by the crystals formed after the foam residue dries, resulting in the floor washer being unable to stably output the cleaning medium. Users need to repeatedly dredge the foam nozzle or return the floor washer to the factory for repair, resulting in a poor user experience.

[0027] Based on this, the present application provides a control method for a cleaning device, which can self-clean the output component of the cleaning device for outputting foam, so as to improve the blockage problem caused by the crystals formed by the foam residue, enable the cleaning device to stably output the cleaning medium, and thus enhance the user experience.

[0028] To facilitate understanding of the control method for the cleaning device provided by the present application, the cleaning device provided by the present application will be described below with reference to the accompanying drawings first.

[0029] See Figures 1 to 3 , the present application provides a cleaning device 1, including a conveying component, a connecting component 14 communicated with the conveying component, at least one output component communicated with the connecting component 14, and a control device. The control device can control the conveying component to convey the cleaning medium to at least one output component through the connecting component 14.

[0030] It should be noted that at least one output component is used to output the corresponding cleaning medium to clean the dirt. The conveying component is used to convey the cleaning medium to at least one output component. The cleaning medium can include one or a combined state of clean water, cleaning liquid and gas, and the present application does not make any restrictions. The connecting component 14 is used to distribute the flow direction and flow rate of the cleaning medium conveyed by the conveying component, etc. The control device can control the conveying component to start and control the connecting component 14 to conduct with at least one output component according to the control instruction executed by the cleaning device 1, so that at least one output component can output the corresponding cleaning medium.

[0031] Thus, the cleaning device 1 provided by the present application can enable at least one output component to output one or a combined state of clean water, cleaning liquid, and gas according to a control instruction. For example, at least one output component can output clean water, cleaning liquid, gas, a mixed liquid of clean water and cleaning liquid, bubble water of clean water and gas, foam of cleaning liquid and gas, etc. In this way, the cleaning device 1 can provide and output a variety of cleaning media to deal with different degrees of dirt.

[0032] It can be understood that the conveying component may include a clean water conveying pipeline, a cleaning liquid conveying pipeline, and a gas conveying pipeline that communicate with the connection component 14, and each conveying pipeline is not shown in the figure. The control device can control at least one of the conveying pipelines to be in an open state, so that at least one output component can output the corresponding cleaning medium. At the same time, for the convenience of conveying the cleaning medium, the conveying component may include a water pump 11 acting on the clean water conveying pipeline, a cleaning liquid pump 12 acting on the cleaning liquid conveying pipeline, and an air pump 13 acting on the gas conveying pipeline. Of course, in other embodiments, the clean water conveying pipeline can also be externally connected to a faucet pipeline to provide conveying power, and the present application does not make any restrictions.

[0033] It can be understood that the connection component 14 may include a pipe fitting 142 communicating with the conveying component, a connection pipeline communicating between the pipe fitting 142 and the output component, and a control valve acting on the connection pipeline. The control valve can be a reversing valve, a stop valve, a pressure valve, a flow valve, etc., and the present application does not make any restrictions.

[0034] See Figure 2 and Figure 3 , in some embodiments, at least one output component may include a first output component 15 and a second output component 17 that communicate with the connection component 14, and the control device can control the connection component 14 to conduct at least one of the first output component 15 and the second output component 17, so that the first output component 15 and the second output component 17 can output the corresponding cleaning medium.

[0035] With this setting, the first output component 15 and the second output component 17 can output the same or different cleaning media respectively, and the first output component 15 and the second output component 17 can be used simultaneously in combination or separately, respectively, to further enrich the usage functions of the cleaning device 1.

[0036] See Figure 3 , in some embodiments, to enrich the foam output by the output component, the cleaning device 1 further includes a foam generator 16, and the foam generator 16 is connected between the connection component 14 and the first output component 15.

[0037] It should be noted that when the control device controls the first output component 15 to output foam, the cleaning liquid pump 12 and the air pump 13 are started, so that the gas and the cleaning liquid flow through the foam generator 16 and are fully mixed in the foam generator 16 to generate rich foam. It can be understood that the water pump 11 can also be started so that the clear water, the cleaning liquid and the gas are mixed in the foam generator 16, and the present application does not make any restrictions.

[0038] In some embodiments, to prevent the first output component 15 from being blocked by the crystals generated after the foam dries, the cleaning device 1 can start the water pump 11 to convey clear water to the first output component 15, so as to use the water flow to wash the pipeline of the first output component 15 and wash away the crystals accumulated after the foam dries in the pipeline, thereby preventing the first output component 15 from being blocked, enabling the cleaning device 1 to stably output the cleaning medium, and improving the operation stability and user satisfaction of the cleaning device 1.

[0039] In some embodiments, the cleaning device 1 further includes a housing assembly 19 and a cleaning brush 18 installed on the housing assembly 19. The cleaning brush 18 is used to perform a cleaning operation on the cleaning surface. The first output component 15 is arranged to face the cleaning surface, and the second output component 17 is arranged to face the cleaning brush 18.

[0040] With such an arrangement, when the cleaning device 1 controls the first output component 15 to output the cleaning medium, the first output component 15 can be used to directly irradiate the dirt on the cleaning surface to output the cleaning medium in a fixed-point and / or quantitative manner, so as to achieve spot spraying cleaning of local dirt or stubborn dirt on the cleaning surface by the user, and enable the cleaning device 1 to have a spot spraying mode. When the cleaning device 1 controls the second output component 17 to output the cleaning medium, the second output component 17 can be used to output the cleaning medium to the cleaning brush 18 to wet the cleaning brush 18, so as to achieve daily general cleaning of the large-area dirt on the cleaning surface by the user using the cleaning brush 18, and enable the cleaning device 1 to have a general mode.

[0041] It can be understood that the first output component 15 includes a nozzle. In the spot spraying mode, the spraying range and spraying force of the nozzle can be adjusted according to the user's usage requirements, and the present application does not make any settings. The second output component 17 includes a liquid spraying plate, and the liquid spraying plate is arranged along the length direction of the cleaning brush 18 and is provided with a plurality of spray holes or strip-shaped spray holes, so that the output cleaning medium can uniformly contact the cleaning brush 18.

[0042] It can be understood that the cleaning surface includes hard surfaces such as the ground or the kitchen countertop, and the cleaning surface also includes soft surfaces such as carpets or sofas, and the present application does not make any restrictions.

[0043] See Figure 2 、 Figure 3 and Figure 5 , Figure 2 is a schematic structural diagram of a cleaning device 1 with two output components shown in an embodiment.Figure 3 The following Figure 2 is a schematic diagram of an internal structure of the cleaning device 1 shown in the figure. Figure 5 The following Figure 2 is another schematic diagram of an internal structure of the cleaning device 1 shown in the figure. In some embodiments, the housing assembly 19 is provided with a receiving cavity, and the air pump 13, the cleaning liquid pump 12, and the water pump 11 of the cleaning device 1 can be installed in the receiving cavity of the housing assembly 19. The installation positions of the pump bodies in the housing assembly 19 are not limited to Figure 3 and Figure 5 the arrangement structures shown in the figure. The manufacturer can also adjust the installation positions of the pump bodies and the conveying pipelines in the housing assembly 19 according to the actual assembly situation to form other arrangement structures, which are not limited in this application.

[0044] It can be understood that the water pump 11 is electrically connected to the control device. The clear water conveyed by the water pump 11 can be used to clean easily cleanable light dirt such as dust or sweat stains, and the clear water can also be used for self-cleaning the cleaning brush 18 of the cleaning device 1. The clear water can be an unpolluted natural water source or domestic water such as groundwater or tap water.

[0045] The cleaning liquid pump 12 is electrically connected to the control device. The cleaning liquid conveyed by the cleaning liquid pump 12 can be used to clean stubborn dirt such as oil stains, mildew, or water scale. The cleaning liquid includes various cleaning liquids such as oil stain cleaning liquid, floor cleaning liquid, fabric cleaning liquid, carpet cleaning liquid, glass cleaning liquid, disinfection cleaning liquid, or mildew removal cleaning liquid, which are not limited in this application.

[0046] The air pump 13 is electrically connected to the control device. The gas conveyed by the air pump 13 can be harmless gas such as air or nitrogen, which is not limited in this application. The gas can also be used to blow off the crystals accumulated on the output assembly after the liquid-containing cleaning medium dries to prevent the output assembly from being blocked. The gas can also be used to dry the water marks after cleaning or to dry the cleaning brush 18 of the cleaning device 1.

[0047] Taking the cleaning device 1 having two output assemblies as an example below, that is, including a first output assembly 15 and a second output assembly 17, this application provides two cleaning devices 1 with different structures.

[0048] Referring to Figure 3 and Figure 4 , Example 1, the connection assembly 14 includes a first reversing valve 141 and a pipe fitting 142. The first reversing valve 141 is provided with at least three working ports. The at least three working ports include a first outlet communicating with the first output assembly 15, a second outlet communicating with the second output assembly 17, and an inlet that selectively conducts between the first outlet and the second outlet. The conveying assembly is connected to the inlet of the first reversing valve 141 through the pipe fitting 142.

[0049] It should be noted that the pipe fitting 142 is used to connect each conveying pipeline in the conveying assembly (such as the clear water conveying pipeline, the cleaning liquid conveying pipeline, and the gas conveying pipeline) to the inlet of the first reversing valve 141. When the output assembly outputs at least two of clear water, cleaning liquid, and gas, the pipe fitting 142 can pre-mix at least two cleaning media and then enter the corresponding output assembly. Among them, the connecting piece includes a four-way pipe joint or two communicating three-way pipe joints, and the present application does not make any restrictions.

[0050] In this way, in the spot spraying mode, by controlling the inlet of the first reversing valve 141 to communicate with the first outlet and starting at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13, the first output assembly 15 can output one or a combined state of clear water, cleaning liquid, and gas.

[0051] In the general mode, by controlling the inlet of the first reversing valve 141 to communicate with the second outlet and starting at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13, the second output assembly 17 can output one or a combined state of clear water, cleaning liquid, and gas.

[0052] Of course, the cleaning device 1 can also enable the spot spraying mode and the general mode simultaneously. Just control the inlet of the first reversing valve 141 to communicate with both the first outlet and the second outlet, and start at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13, then the first output assembly 15 and the second output assembly 17 can output the cleaning media simultaneously.

[0053] See Figure 5 and Figure 6 , Example 2, the connection assembly 14 includes a second reversing valve 143, a first stop valve 144, and a second stop valve 145. The second reversing valve 143 is provided with at least three working ports. The at least three working ports include a first outlet communicating with the first stop valve 144, a second outlet communicating with the second stop valve 145, and an inlet communicating with the first outlet and the second outlet. The first output assembly 15 and the air pump 13 are respectively connected to the first stop valve 144, and the second output assembly 17 and the water pump 11 are respectively connected to the second stop valve 145.

[0054] It should be noted that the difference between Example 2 and Example 1 is that in Example 2, only the cleaning liquid pump 12 is connected to the inlet of the second reversing valve 143, the air pump 13 and the first output assembly 15 are respectively connected to the first stop valve 144, and the water pump 11 and the second output assembly 17 are respectively connected to the second stop valve 145. In this way, through the second reversing valve 143, it can be controlled that the first output assembly 15 and the second output assembly 17 can respectively output the cleaning media containing cleaning liquid. And the air pump 13 can be directly connected to the first output assembly 15 without passing through the second reversing valve 143, and the water pump 11 can be directly connected to the second output assembly 17 without passing through the second reversing valve 143.

[0055] In this way, in the spot spraying mode, the inlet of the second reversing valve 143 is controlled to communicate with the first outlet, the first cut-off valve 144 is opened, and the second cut-off valve 145 is closed, and at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13 is controlled to start, so that the first output assembly 15 can output one or a combined state of clean water, cleaning liquid, and gas.

[0056] In the general mode, the inlet of the first reversing valve 141 is controlled to communicate with the second outlet, the first cut-off valve 144 is closed, and the second cut-off valve 145 is opened, and at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13 is controlled to start, so that the second output assembly 17 can output one or a combined state of clean water, cleaning liquid, and gas.

[0057] Of course, the cleaning device 1 can also enable the spot spraying mode and the general mode at the same time. Just control the inlet of the first reversing valve 141 to communicate with both the first outlet and the second outlet, the first cut-off valve 144 and the second cut-off valve 145 are opened respectively, and at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13 is controlled to start, then the first output assembly 15 and the second output assembly 17 can output the cleaning medium at the same time.

[0058] It can be understood that the first reversing valve 141 and the second reversing valve 143 can be two-way three-way valves, three-way three-way valves, four-way valves, five-way valves, etc., and the present application does not make any restrictions.

[0059] It can be understood that in some embodiments, to reduce pipeline connections, the foam generator 16 connected between the first outlet and the first output assembly 15 can be integrally arranged with the first output assembly 15.

[0060] In addition, in other embodiments, the output assembly of the cleaning device 1 can also be provided with any number required by the user, such as 1, 3, 4, or 5, etc., and the present application does not make any restrictions.

[0061] In some embodiments, the cleaning device 1 further includes a sewage suction assembly capable of recovering dirt by negative pressure suction. The sewage suction assembly includes a sewage tank 50, a sewage suction pipe communicated with the sewage tank 50, and a suction device (not shown in the figure) acting on the sewage suction pipe. For example, during the process of the cleaning device 1 cleaning dirt, the cleaning device 1 can start the suction device, and the suction device uses negative pressure suction to suck liquid dirt and / or solid dirt into the sewage suction pipe and recover it into the sewage tank 50, and the user only needs to regularly pour out the dirt in the sewage tank 50.

[0062] See you again Figures 1 to 3, in some embodiments, the cleaning device 1 can be used in conjunction with the base station 2. The base station 2 can be used to connect to an external power adapter and is electrically connected to a power source through the power adapter. When the cleaning device 1 is docked with the base station 2, the base station 2 can serve as a charging device for the cleaning device 1 to supply power to the cleaning device 1. When the cleaning device 1 is separated from the base station 2, the cleaning device 1 can carry the cleaning brush 18 away from the base station 2 to perform cleaning operations on the cleaning surface, such as cleaning the floor, including cleaning operations such as vacuuming, sweeping, and mopping.

[0063] In addition, the base station 2 also has a cleaning tank 21. When the cleaning device 1 is docked with the base station 2, the cleaning brush 18 of the cleaning device 1 can be located within the cleaning tank 21 of the base station 2. Thus, through signal transmission between the base station 2 and the cleaning device 1, the base station 2 can perform maintenance on the cleaning device 1 according to operation instructions. For example, when the cleaning device 1 is docked with the base station 2, it can be used to perform self-cleaning maintenance on the cleaning device 1 and perform operations such as automatic water supply and drainage for the cleaning device 1. Among them, the self-cleaning maintenance of the cleaning device 1 includes cleaning the cleaning brush 18, drying the cleaning brush 18, cleaning the pipeline for transporting the cleaning medium, and cleaning the sewage tank 50 for recycling dirt.

[0064] See Figures 1 to 3 , hereinafter, the cleaning device 1 being a floor washer will be taken as an example for illustration. The cleaning device 1 includes a floor brush device 10, a main body device 20, a clean water tank 30, and a cleaning liquid tank 40. The floor brush device 10, the clean water tank 30, and the cleaning liquid tank 40 can be respectively installed on the main body device 20 to facilitate replenishment of clean water and cleaning liquid. Of course, the cleaning liquid tank 40 can also be installed within the floor brush device 10, and the present application does not make any restrictions.

[0065] The main body device 20 includes a handle to facilitate the user to hold. The floor brush device 10 includes a housing assembly 19, a conveying assembly disposed within the housing assembly 19, a connecting assembly 14, etc. The clean water tank 30 is communicated with a water pump 11, and the cleaning liquid tank 40 is communicated with a cleaning liquid pump 12.

[0066] It can be understood that the cleaning device 1 can be used in conjunction with the base station 2, and the base station 2 is used to charge or maintain the cleaning device 1. The control device includes operation buttons installed on the main body device 20 and a controller electrically connected to the operation buttons. The controller is electrically connected to the connecting assembly 14 to switch the conduction state between the connecting assembly 14 and at least one output assembly through the operation buttons, thereby switching the spot spraying mode and the general mode of the floor washer. Of course, the controller can also be electrically connected to mobile devices such as mobile phones, computers, or tablets, enabling the user to operate and switch various cleaning modes through corresponding application software or application programs within the mobile devices such as mobile phones, computers, or tablets.

[0067] Understandably, the cleaning device 1 provided in the present application is not limited to a floor washer, and may also include a floor sweeping robot, a vacuum cleaner, a carpet cleaning machine, a fabric cleaning machine, etc., and the present application does not make any restrictions.

[0068] In addition to the above-mentioned cleaning device 1, the present application also provides a control method for the cleaning device 1. The control method for the cleaning device 1 provided in the present application will be described below.

[0069] The control method provided in the present application includes:

[0070] Step 1: In response to the start operation of the self-cleaning mode, execute the self-cleaning mode.

[0071] Step 11: When the self-cleaning mode indicates self-cleaning of the first output component 15, control the connection component 14 to conduct with the first output component 15, and control the conveying component to start and convey clean water to the first output component 15 until the first preset condition is met and then turn off.

[0072] Understandably, the cleaning device 1 includes a conveying component, a connection component 14 communicated with the conveying component, at least one output component communicated with the connection component 14, and a control device. The control device can control the conveying component to convey a cleaning medium to at least one output component through the connection component 14. Among them, at least one output component includes a first output component 15. The cleaning device 1 can output a cleaning medium in a state of one or a combination of clean water, cleaning liquid, and gas through the first output component 15.

[0073] To prevent the first output component 15 from being blocked due to crystallization caused by the drying of foam after output, the cleaning device 1 provided in the present application can perform self-cleaning on the first output component 15. The control method provided in the present application can execute the self-cleaning mode in response to the start operation of the self-cleaning mode.

[0074] Specifically, when the self-cleaning mode indicates self-cleaning of the first output component 15, the control method can control the connection component 14 to conduct with the first output component 15, and control the conveying component to start and convey clean water to the first output component 15 until the first preset condition is met and then turn off. In this way, the control method provided in the present application can perform self-cleaning on the first output component 15, that is, by outputting clean water to the first output component 15, using the water flow to wash the pipeline of the first output component 15 and wash away the crystals accumulated after the foam dries in the pipeline, thereby preventing the first output component 15 from being blocked, enabling the cleaning device 1 to stably output the cleaning medium, and improving the operation stability and user satisfaction of the cleaning device 1.

[0075] Understandably, the self-cleaning operation of the cleaning device 1 can be a signal generated by the cleaning device 1 itself. In one example, the self-cleaning operation can be a self-cleaning control signal generated according to the docking time between the cleaning device 1 and the base station 2 after the cleaning device 1 is docked with the base station 2. For example, it is set that when the docking time between the cleaning device 1 and the base station 2 exceeds 2 minutes, the cleaning device 1 is self-cleaned. In another example, the self-cleaning operation can also be a control signal generated by a user operation. For example, the cleaning device 1 is provided with a self-cleaning button, and the user can operate the self-cleaning button to generate a start instruction to start the self-cleaning mode. When the user operates the self-cleaning button again, a stop instruction to stop the self-cleaning mode can be generated. Of course, the self-cleaning operation can also be controlled and executed in other ways, such as the user controlling the start of the self-cleaning operation of the cleaning device 1 through devices such as mobile phones or computers, and the present application does not limit this.

[0076] In some embodiments, controlling the conveying assembly to start and convey clean water to the first output assembly 15 until a first preset condition is met and then closing it includes at least one of the following:

[0077] Controlling the conveying assembly to stop conveying clean water according to a built-in delay program.

[0078] Controlling the conveying assembly to stop conveying clean water according to the closing signal received from the detection device, where the detection device is used to send a closing signal when the self-cleaning of the first output assembly 15 meets the requirements.

[0079] Responding to the input instruction of the operation button on the cleaning device 1, controlling the conveying assembly to stop conveying clean water.

[0080] It should be noted that the first preset condition can be the preset duration of the delay program built in the control device, and the control device controls the water pump 11 to close according to the preset duration of the delay program to stop conveying clean water. Of course, the first preset condition can also be to detect the residual state of the foam crystals by the detection device. If the residual crystals have been rinsed off and meet the rinsing requirements, the water pump 11 is controlled to close. Of course, the water pump 11 can also be closed according to the user input instruction, and the present application does not limit this.

[0081] In some embodiments, step 11 further includes: after the conveying assembly stops conveying clean water to the first output assembly 15, controlling the airflow to act on the first output assembly 15.

[0082] With this setting, on the one hand, the airflow can be used to dry the residual liquid in the first output assembly 15 to prevent the residual liquid from flowing out when the first output assembly 15 outputs foam or cleaning liquid, which affects the user experience. On the other hand, the airflow can also be used to impact the foam crystals that may not have been rinsed off by the clean water again, realizing double self-cleaning of the first output assembly 15 by water flow and airflow to avoid blockage.

[0083] In some embodiments, the cleaning device 1 further includes a sewage suction assembly capable of recovering dirt by negative pressure suction. Controlling the airflow to act on the first output assembly 15 includes at least one of the following:

[0084] Control the conveying assembly to start and convey positive pressure air flow or negative pressure air flow to the first output assembly 15.

[0085] Control the sewage suction assembly to start and output negative pressure air flow to the first output assembly 15.

[0086] It can be understood that the sewage suction assembly includes a sewage tank 50, a sewage suction pipe communicated with the sewage tank 50, and a suction device acting on the sewage suction pipe. For example, during the process of the cleaning device 1 cleaning dirt, the cleaning device 1 can start the suction device, and the suction device uses negative pressure suction to suck liquid dirt and / or solid dirt into the sewage suction pipe and recover it into the sewage tank 50. The user only needs to regularly pour out the dirt in the sewage tank 50.

[0087] In this way, the air flow acting on the first output assembly 15 can be from the air pump 13 of the conveying assembly or from the suction device of the suction assembly. The air pump 13 can output positive pressure air flow to the first output assembly 15 so that the positive pressure air flow can be discharged from the first output assembly 15, thereby drying the residual liquid and blowing out the crystals. Of course, the air pump 13 and the suction assembly can also output negative pressure air flow to the first output assembly 15, and use negative pressure suction to suck the residual liquid and crystals back into the interior of the cleaning device 1 or the sewage tank 50. The present application does not limit the source of the air flow.

[0088] In some embodiments, when the cleaning device 1 performs self-cleaning on the first output assembly 15, the cleaning device 1 can also perform self-cleaning on the sewage suction pipe of the sewage suction assembly. It can be understood that when the cleaning device 1 is docked with the base station 2, the clean water conveyed by the conveying assembly to the first output assembly 15 flows into the cleaning tank 21 of the base station 2. At this time, when the cleaning device 1 starts the sewage suction assembly, it can use negative pressure suction to suck the liquid in the cleaning tank 21 into the sewage suction pipe to perform self-cleaning on the sewage suction pipe.

[0089] Specifically, step 11 of the control method further includes: controlling the suction device to start, so that the liquid in the cleaning tank 21 flows in the sewage suction pipe and is sucked into the sewage tank 50 when it meets the second preset condition, so as to perform self-cleaning on the sewage suction pipe at the same time.

[0090] In some embodiments, when the cleaning device 1 performs self-cleaning on the sewage suction pipe, the liquid in the cleaning tank 21 can flow back and forth in the sewage suction pipe to wash the pipe, thereby improving the cleaning strength of the sewage suction pipe. In this way, the control method can control the suction device to repeatedly suck the liquid in the cleaning tank 21 into the sewage suction pipe until the liquid in the cleaning tank 21 is sucked into the sewage tank 50 when it meets the second preset condition.

[0091] In some embodiments, the second preset condition includes at least one of the following: (1) Controlling the suction device to reciprocally suck the liquid in the cleaning tank 21 into the sewage suction pipeline and after reaching a preset number of times, then suck it into the sewage tank 50. For example, if the preset number of times is 2 times, the suction device needs to suck the liquid in the cleaning tank 21 into the sewage suction pipeline and then discharge it back into the cleaning tank 21 to form the first flushing. After that, the suction device needs to suck the liquid in the cleaning tank 21 into the sewage suction pipeline again and then discharge it back into the cleaning tank 21 to form the second flushing. Finally, the suction device directly sucks the liquid in the cleaning tank 21 into the sewage tank 50 through the sewage suction pipeline to complete the self-cleaning of the sewage suction pipeline. In this way, the cleaning intensity of the sewage suction pipeline is improved by reciprocally flushing twice. Of course, the preset number of times is not limited to 2 times, and can also be 3 times, 4 times, 5 times, etc., and this application does not make any restrictions. (2) Controlling the suction device to reciprocally suck the liquid in the cleaning tank 21 into the sewage suction pipeline and after reaching a preset time, then suck it into the sewage tank 50. For example, if the preset time is 5 minutes, the suction device needs to continuously suck the liquid in the cleaning tank 21 into the sewage suction pipeline and then discharge it back into the cleaning tank 21 within 5 minutes to reciprocally clean the sewage suction pipeline until after 5 minutes of flushing, the liquid in the cleaning tank 21 is sucked into the sewage tank 50. (3) Controlling the suction device to suck the liquid in the cleaning tank 21 into the sewage tank 50 according to the received closing signal. For example, the suction device can suck the liquid in the cleaning tank 21 into the sewage tank 50 after reciprocally flushing according to the user's key operation.

[0092] In some embodiments, to facilitate the reciprocating flushing of the sewage suction pipeline, the suction device has a first power and a sewage suction power greater than the first power, that is, the negative pressure suction force when the suction device operates at the first power is less than the negative pressure suction force when it operates at the sewage suction power. In this way, when the suction device operates at the first power, the negative pressure suction force generated by the suction device is relatively small, and it can meet the requirement of sucking the liquid in the cleaning tank 21 into the sewage suction pipeline without sucking it into the sewage tank 50. When the suction device operates at the sewage suction power, the negative pressure suction force generated by the suction device is relatively large, and it can meet the requirement of sucking the liquid in the cleaning tank 21 into the sewage tank 50.

[0093] In this way, to facilitate the reciprocating flushing of the sewage suction pipeline, step 11 of the control method further includes: controlling the suction device to intermittently operate at the first power, or controlling the suction device to alternately operate in forward and reverse.

[0094] With such a setting, when the suction device operates at the first power, a negative pressure suction force is generated in the sewage suction pipe to suck the liquid in the cleaning tank 21 into the sewage suction pipe for flushing. When the suction device stops operating, the negative pressure suction in the sewage suction pipe disappears, and the liquid in the sewage suction pipe can be released and flow back into the cleaning tank 21. When the suction device operates at the first power again, the suction device can suck the liquid in the cleaning tank 21 into the sewage suction pipe again to achieve reciprocating cleaning of the sewage suction pipe. In this way, the liquid in the cleaning tank 21 can be reciprocally sucked in and out of the sewage suction pipe, thereby forming a surge flushing, which can improve the cleaning area and cleaning strength of the sewage suction pipe.

[0095] In addition, in other embodiments, the suction device can also rotate forward and backward, and the liquid in the cleaning tank 21 can be sucked into or discharged from the sewage suction pipe by the alternating operation of the forward and reverse rotation of the suction device. This application does not make any restrictions. As an example, when the suction device rotates forward, the suction device generates a negative pressure suction force to suck the liquid in the cleaning tank 21 into the sewage suction pipe. When the suction device rotates backward, the suction device generates a positive pressure suction force to discharge the liquid in the cleaning tank 21 from the sewage suction pipe into the cleaning tank 21. Conversely, when the suction device generates a positive pressure suction force when rotating forward and a negative pressure suction force when rotating backward, this application will not elaborate.

[0096] In some embodiments, to further improve the cleaning strength of the sewage suction pipe, the suction device also has a second power that is less than the first power and can satisfy sucking the liquid in the cleaning tank 21 into the sewage suction pipe. Controlling the suction device to reciprocally suck the liquid in the cleaning tank 21 into the sewage suction pipe further includes: controlling the suction device to alternately operate at the first power and the second power.

[0097] It should be noted that when the suction device alternately operates at the first power and the second power, it is equivalent to the suction device being able to alternately suck the liquid in the cleaning tank 21 into the sewage suction pipe with two different magnitudes of negative pressure suction forces, so that the liquid in the cleaning tank 21 reciprocally sucks in and out in the sewage suction pipe to form a surge, thereby using the fluctuation of the surge to increase the flushing area and flushing strength of the liquid in the sewage suction pipe and improve the cleaning power of the sewage suction pipe.

[0098] At the same time, when the suction device alternately operates at the first power and the second power, the suction device does not need to be frequently started and stopped, which can extend the service life of the suction device and save energy consumption.

[0099] It can be understood that the first power of the suction device can be 30% to 50% of the sewage suction power, and the second power can be 10% to 20% of the sewage suction power. This application does not make any restrictions on this, and the first power and the second power of the suction device can be adjusted according to the actual use scenario.

[0100] In some embodiments, the cleaning device 1 further includes a cleaning brush 18, a second output component 17, and a driving component. The cleaning brush 18 is used to perform a cleaning operation on the cleaning surface. The first output component 15 is arranged facing the cleaning surface. The second output component 17 is arranged facing the cleaning brush 18 and communicated with the connecting component 14. The driving component is used to drive the cleaning brush 18 to rotate. When the cleaning device 1 cleans dirt, the driving component drives the cleaning brush 18 to rotate, and the dirt can be wiped reciprocally to clean the dirt. After the cleaning device 1 is docked with the base station 2, the cleaning brush 18 is located in the cleaning tank 21 of the base station 2. At this time, the driving component drives the cleaning brush 18 to rotate, so that the cleaning brush 18 can rub against the liquid in the cleaning tank 21, thereby self-cleaning the cleaning brush 18 as well.

[0101] Thus, step 11 of the control method further includes: controlling the connecting component 14 to be conducted with both the first output component 15 and the second output component 17, controlling the conveying component to start conveying the cleaning medium to both the first output component 15 and the second output component 17, and controlling the driving component to drive the cleaning brush 18 to rotate, so as to simultaneously self-clean the cleaning brush 18.

[0102] With such a setting, when the cleaning device 1 self-cleans the first output component 15, at least one of the sewage suction pipeline and the cleaning brush 18 can be cleaned simultaneously.

[0103] When self-cleaning the cleaning brush 18, the water pump 11 of the conveying component can conduct both the first output component 15 and the second output component 17 at the same time, so that clean water flushes the first output component 15 to prevent foam from drying and crystallizing to block the first output component 15, and also enables clean water to be output from the second output component 17 to flush and wet the cleaning brush 18. The clean water flowing out from the two output components can be stored in the cleaning tank 21 of the base station 2. When it is necessary to increase the cleaning intensity of the cleaning brush 18, on the one hand, the control method can control the cleaning liquid pump 12 to start and conduct to the second output component 17 to output the cleaning liquid to the cleaning brush 18 to further dissolve the dirt on the cleaning brush 18. Of course, when the cleaning liquid pump 12 starts, the air pump 13 can also be controlled to start and conduct to the second output component 17, so that the gas is mixed with the cleaning liquid to form foam and output to the cleaning brush 18 for dissolving the dirt on the cleaning brush 18. This application does not limit this. On the other hand, the control method can control the driving component to drive the cleaning brush 18 to rotate to increase the contact area between the cleaning brush 18 and the cleaning medium and the flushing force. It can be understood that the driving component can drive the cleaning brush 18 to rotate forward or backward so that the cleaning brush 18 can uniformly contact the cleaning medium. In addition, when the driving component drives the cleaning brush 18 to rotate, the cleaning brush 18 can also drive the liquid in the cleaning tank 21 to fluctuate, so that the cleaning brush 18 impacts and beats with the liquid reciprocally, thereby improving the cleaning intensity of the cleaning brush 18.

[0104] Understandably, the driving assembly includes a motor and a transmission mechanism connected between the motor and the cleaning brush 18. The transmission mechanism can be a gear mechanism, a link mechanism, a belt drive mechanism, etc., and the present application does not make any limitations.

[0105] In some embodiments, to improve the cleaning effect, the cleaning device 1 and / or the base station 2 further includes a heating assembly. When the self-cleaning mode indicates self-cleaning of the first output assembly 15, it further includes: controlling the heating assembly on the cleaning device 1 to heat the cleaning medium conveyed by the conveying assembly, and / or controlling the heating assembly on the base station 2 to heat the liquid in the cleaning tank 21.

[0106] With such a setting, heating the cleaning medium can accelerate the dissolution of dirt and help improve the cleaning effect. Understandably, the heating assembly includes a PTC heater, an electric heating wire, etc. The heating assembly can be arranged on at least one of the base station 2 and the cleaning device 1, and the present application does not make any limitations.

[0107] Taking the case where the cleaning device 1 docks with the base station 2 and the cleaning device 1 performs self-cleaning on the first output assembly 15, the suction pipeline, and the cleaning brush 18 as an example, the control process of the control method is as follows:

[0108] In response to the start operation of self-cleaning, the control connection component 14 is controlled to conduct to the first output component 15, and the water pump 11 is controlled to start. At this time, the water pump 11 outputs clean water to the first output component 15 to perform self-cleaning on the first output component 15. During the self-cleaning of the first output component 15, the water flows into the cleaning tank 21 of the base station 2. The suction device is controlled to start and operate at the sewage suction power to suck the liquid in the cleaning tank 21 into the sewage tank 50, perform preliminary self-cleaning on the sewage suction pipeline, and also prevent the liquid in the cleaning tank 21 from overflowing. After that, the suction device is controlled to alternately operate at the first power and the second power to reciprocally suck the liquid in the cleaning tank 21 into the sewage suction pipeline to form a surge, so as to perform the first surge flushing on the sewage suction pipeline. At the same time, since the suction device only sucks the liquid in the cleaning tank 21 into the sewage suction pipeline but not into the sewage tank 50, the water flow output by the water pump 11 can gradually store water in the cleaning tank 21 and wet the cleaning brush 18. At this time, the control driving component drives the cleaning brush 18 to rotate, and the cleaning brush 18 can be synchronously self-cleaned. After that, the suction device is controlled to operate at the sewage suction power to suck the liquid in the cleaning tank 21 into the sewage tank 50 to prevent the liquid from overflowing. After that, the suction device is controlled to alternately operate at the first power and the second power to perform the second surge flushing on the sewage suction pipeline, and the control driving component drives the cleaning brush 18 to alternately rotate forward and backward to improve the cleaning strength of the cleaning brush 18. At this time, at least one of the cleaning liquid pump 12 and the air pump 13 can be selected to start during the first surge flushing or the second surge flushing process and conduct to the second output component 17 to output cleaning liquid or foam to the cleaning brush 18, thereby improving the cleaning strength. After that, the water pump 11 is controlled to stop, and the self-cleaning of the first output component 15 is completed. The remaining liquid in the cleaning tank 21 of the base station 2 can continue to supply water for the self-cleaning of the sewage suction pipeline and the cleaning brush 18. After the self-cleaning of the cleaning brush 18 is completed, the suction device is controlled to operate at the sewage suction power to suck the remaining liquid in the cleaning tank 21 into the sewage tank 50 to complete the entire self-cleaning mode. It can be understood that the above control method is taken as an example.

[0109] In some embodiments, the conveying component includes a clean water conveying pipeline communicated with the connection component 14 and a water pump 11 acting on the clean water conveying pipeline, a cleaning liquid conveying pipeline communicated with the connection component 14 and a cleaning liquid pump 12 acting on the cleaning liquid conveying pipeline, and a gas conveying pipeline communicated with the connection component 14 and acting on the gas conveying pipeline. The control method further includes:

[0110] Step 2, in response to the start operation of the cleaning mode, execute the cleaning mode. Among them, the cleaning mode includes at least one of a clean water mode, a cleaning liquid mode, a gas mode, a foam mode, a mixed liquid mode, and a bubble water mode.

[0111] In some embodiments, the cleaning device 1 includes a first output component 15 and a second output component 17 that communicate with the connection component 14. The second output component 17 is arranged to face the cleaning brush 18, and the first output component 15 is arranged to face the cleaning surface for performing a cleaning operation on the cleaning brush 18. The cleaning mode further includes a spot spraying mode and a general mode. Step 2 further includes at least one of the following:

[0112] Step 21: When the cleaning mode indicates starting the spot spraying mode, control the connection component 14 to conduct the first output component 15 so that the first output component 15 can correspondingly output a cleaning medium, and the cleaning medium includes one or a combined state of clear water, cleaning liquid, and gas.

[0113] Step 22: When the cleaning mode indicates starting the general mode, control the connection component 14 to conduct the second output component 17 so that the second output component 17 can correspondingly output a cleaning medium, and the cleaning medium includes one or a combined state of clear water, cleaning liquid, and gas.

[0114] Step 23: When the cleaning mode indicates starting the spot spraying mode and the general mode, control the connection component 14 to conduct the first output component 15 and the second output component 17 so that the first output component 15 and the second output component 17 can respectively output a cleaning medium, and the cleaning medium includes one or a combined state of clear water, cleaning liquid, and gas.

[0115] In some embodiments, when the cleaning device 1 is in the spot spraying mode and / or the general mode, controlling at least one of the water pump 11, the cleaning liquid pump 12, and the air pump 13 to open can enable the cleaning device 1 to have different cleaning modes. The different cleaning modes of the cleaning device 1 will be described below.

[0116] In the spot spraying mode, the first output component 15 outputs a cleaning medium. The cleaning medium includes one or a combined state of clear water, cleaning liquid, and gas. Accordingly, the cleaning mode of the cleaning device 1 includes at least one of a clear water mode, a cleaning liquid mode, a gas mode, a foam mode, a mixed liquid mode, and a bubble water mode. At this time, step 21 of the control method further includes at least one of the following:

[0117] Step 211: When the cleaning mode includes the clear water mode, control the water pump 11 and the air pump 13 to start, and control the cleaning liquid pump 12 to be in a closed state.

[0118] Step 212: When the cleaning mode includes the cleaning liquid mode, control the cleaning liquid pump 12 to start, and control the air pump 13 and the water pump 11 to be in closed states respectively.

[0119] Step 213: When the cleaning mode includes the gas mode, control the air pump 13 to start, and control the water pump 11 and the cleaning liquid pump 12 to be in closed states respectively.

[0120] Step 214: When the cleaning mode includes the foam mode, control the cleaning liquid pump 12 and the air pump 13 to start, and control the water pump 11 to be in the off state.

[0121] Step 215: When the cleaning mode includes the mixed liquid mode, control the water pump 11 and the cleaning liquid pump 12 to start, and control the air pump 13 to be in the off state.

[0122] Step 216: When the cleaning mode includes the bubble water mode, control the water pump 11 and the air pump 13 to start, and control the cleaning liquid pump 12 to be in the off state.

[0123] It should be noted that in the spot spraying mode, the present application does not limit the usage order of various cleaning modes of the cleaning device 1, and the user can select according to actual needs. Among them, different cleaning modes can correspond to different usage scenarios when performing spot spraying. Specifically, when spot spraying clean water, it can clean light dirt on the cleaning surface, or clean the residual cleaning liquid crystals in the first output component 15 by spot spraying clean water to prevent the first output component 15 from being blocked. When spot spraying a cleaning medium containing a cleaning liquid, such as a cleaning liquid, foam, and mixed liquid, etc., it can be used to clean stubborn dirt on the cleaning surface. When spot spraying gas, it can dry the water marks on the cleaning surface, or blow off the residual cleaning liquid crystals in the first output component 15 by gas to prevent the first output component 15 from being blocked.

[0124] In the general mode, the second output component 17 outputs a cleaning medium. The cleaning medium includes one or a combined state of clean water, a cleaning liquid, and gas. Thus, the cleaning mode of the cleaning device 1 includes at least one of a clean water mode, a cleaning liquid mode, a gas mode, a foam mode, a mixed liquid mode, and a bubble water mode. At this time, step 22 of the control method further includes at least one of the following:

[0125] Step 221: When the cleaning mode includes the clean water mode, control the water pump 11 to start, and control the cleaning liquid pump 12 and the air pump 13 to be in the off state respectively.

[0126] Step 222: When the cleaning mode includes the cleaning liquid mode, control the cleaning liquid pump 12 to start, and control the air pump 13 and the water pump 11 to be in the off state respectively.

[0127] Step 223: When the cleaning mode includes the gas mode, control the air pump 13 to start, and control the water pump 11 and the cleaning liquid pump 12 to be in the off state respectively.

[0128] Step 224: When the cleaning mode includes the foam mode, control the cleaning liquid pump 12 and the air pump 13 to start, and control the water pump 11 to be in the off state.

[0129] Step 225: When the cleaning mode includes the mixed liquid mode, the water pump 11 and the cleaning liquid pump 12 are controlled to start, and the air pump 13 is controlled to be in an off state.

[0130] Step 226: When the cleaning mode includes the bubble water mode, the water pump 11 and the air pump 13 are controlled to start, and the cleaning liquid pump 12 is controlled to be in an off state.

[0131] It should be noted that, in the general mode, the order of using the various cleaning modes of the cleaning device 1 is not limited in this application, and the user can choose according to actual needs. Among them, executing different cleaning modes in the general mode can correspond to different usage scenarios, as follows:

[0132] If only the water pump 11 of the cleaning device 1 is started, and the cleaning liquid pump 12 and the air pump 13 are turned off, the second output component 17 can output clean water to the cleaning brush 18, and the cleaning device 1 is in the clean water mode. For example, the clean water mode can be used to soak the cleaning brush 18 with clean water to clean the light dirt on the floor or carpet to be cleaned. Alternatively, the clean water mode can also perform self-cleaning on the cleaning brush 18 of the cleaning device 1 itself to wash away the dirt on the cleaning brush 18. Alternatively, the clean water output in the clean water mode can also wash away the cleaning medium containing the cleaning liquid remaining in the pipeline of the second output component 17 to prevent the cleaning medium containing the cleaning liquid from forming crystals after drying, thereby avoiding clogging of the second output component 17.

[0133] If only the cleaning liquid pump 12 of the cleaning device 1 is started, and the water pump 11 and the air pump 13 are turned off, the second output component 17 can output cleaning liquid to the cleaning brush 18, and the cleaning device 1 is in the cleaning liquid mode, so as to enhance the cleaning power of the cleaning device 1 on the ground or carpet to be cleaned, or the cleaning power of the cleaning brush 18. Generally, the cleaning liquid has a certain fluidity. When the cleaning liquid is output to a relatively flat surface to be cleaned, such as the ground, glass or kitchen countertop, the cleaning liquid can flow on the surface of the liquid to be cleaned to dissolve and clean the dirt, which can not only improve the cleaning power, but also be suitable for cleaning large areas of stubborn dirt. When the cleaning liquid is output to the carpet or fabric to be cleaned, the cleaning liquid can also penetrate deep into the stains, dissolve stubborn stains, and thus enhance the cleaning power.

[0134] If the water pump 11 and the cleaning liquid pump 12 of the cleaning device 1 are both started and the air pump 13 is closed, the second output component 17 can output a mixed liquid to the cleaning brush 18, and the cleaning device 1 is in the mixed liquid mode. It can be understood that, compared with the cleaning liquid mode, the concentration of the cleaning liquid in the mixed liquid in the mixed liquid mode is lower than that in the cleaning liquid mode. Equivalently, the cleaning liquid is diluted with clean water to form a mixed liquid. The cleaning power of the mixed liquid mode is higher than that of the clean water mode and lower than that of the cleaning liquid mode. The user can choose to use the mixed liquid mode according to the degree of dirt or customized usage requirements, and this application does not make any restrictions. In addition, through the mixed liquid mode, the cleaning power can be improved compared with the clean water mode, and the consumption of the cleaning liquid can be saved compared with the cleaning liquid mode.

[0135] If the water pump 11 and the air pump 13 of the cleaning device 1 are started and the cleaning liquid pump 12 is closed, the second output component 17 can evenly output bubble water to the cleaning brush 18, and the cleaning device 1 is in the bubble water mode. It can be understood that the bubble water mode makes the clean water sprayed evenly, which can avoid uneven cleaning of dirt and reduce the residue of water marks. This application does not make any restrictions on the particle size of the water droplets in the bubble water.

[0136] If the cleaning liquid pump 12 and the air pump 13 of the cleaning device 1 are started and the water pump 11 is closed, the second output component 17 can output cleaning liquid foam to the cleaning brush 18. If the water pump 11, the cleaning liquid pump 12 and the air pump 13 of the cleaning device 1 are started, the second output component 17 can output mixed liquid foam to the cleaning brush 18. The cleaning device 1 is in the foam mode. It can be understood that the concentration of the cleaning liquid in the cleaning liquid foam is higher than that in the mixed liquid foam. The user can choose to output cleaning liquid foam or mixed liquid foam according to the degree of dirt, and this application does not make any restrictions. Compared with the liquid, the foam has weaker fluidity, so the foam can adhere to the vertical surface or complex surface (such as the wall or corner), so that the foam can stay on the dirty surface for a long time, and then dissolve and clean the stubborn dirt. Moreover, the output component can accumulate a thicker foam layer on the dirty surface, improve the persistence of decomposing dirt, and thus improve the cleaning effect. In addition, when the second output component 17 outputs foam, the user can also use the foam to draw different patterns to cover the dirt to improve the cleaning interest and visual effect.

[0137] If the air pump 13 of the cleaning device 1 is started and the cleaning liquid pump 12 and the water pump 11 are closed, the second output component 17 can output gas to the cleaning brush 18. The cleaning device 1 is in the gas mode, which is used to dry the cleaning brush 18. That is, after the used cleaning brush 18 is cleaned by the cleaning device 1, the gas blown out by the second output component 17 can also be used to dry the cleaning brush 18 to prevent the cleaning brush 18 from getting damp and moldy. Alternatively, the gas mode can also be used to blow off the crystals formed after the cleaning medium containing the cleaning liquid on the second output component 17 dries, preventing the second output component 17 from being blocked. Alternatively, the gas mode can also be used to dry the residual cleaning water marks on the floor or carpet to be cleaned, so as to dry the floor or carpet to be cleaned and achieve drying while mopping. It can be understood that the output gas can be harmless gases such as air or nitrogen.

[0138] Taking the cleaning device 1 with two output components as an example, that is, including the first output component 15 and the second output component 17, the present application provides two cleaning devices 1 with different structures. Based on these two cleaning devices 1 with different structures, the control methods are also correspondingly different. The control methods will be described separately below.

[0139] See Figure 3 and Figure 4 In the cleaning device 1 of Example 1, the connection component 14 includes a first reversing valve 141 and a pipe connector 142. The first reversing valve 141 is provided with at least three working ports. The at least three working ports include a first outlet communicating with the first output component 15, a second outlet communicating with the second output component 17, and an inlet that selectively conducts between the first outlet and the second outlet. The conveying component is connected to the inlet of the first reversing valve 141 through the pipe connector 142.

[0140] Step 21 includes: controlling the inlet of the first reversing valve 141 to conduct with the first outlet.

[0141] Step 22 includes: controlling the inlet of the first reversing valve 141 to conduct with the second outlet.

[0142] Step 23 includes: controlling the inlet of the first reversing valve 141 to conduct with both the first outlet and the second outlet.

[0143] See Figure 5 and Figure 6, in the cleaning device 1 of Example 2, the connection component 14 includes a second reversing valve 143, a first stop valve 144, and a second stop valve 145. The second reversing valve 143 is provided with at least three working ports. The at least three working ports include a first outlet communicating with the first stop valve 144, a second outlet communicating with the second stop valve 145, and an inlet communicating with the first outlet and the second outlet. The conveying component includes a water pump 11, a cleaning liquid pump 12, and an air pump 13. The cleaning liquid pump 12 is communicated with the inlet of the second reversing valve 143. The first output component 15 and the air pump 13 are respectively communicated with the first stop valve 144. The second output component 17 and the water pump 11 are respectively communicated with the second stop valve 145.

[0144] Step 21 includes: controlling the inlet of the second reversing valve 143 to be communicated with the first outlet, the first stop valve 144 to be in an open state, and the second stop valve 145 to be in a closed state.

[0145] Step 22 includes: controlling the inlet of the second reversing valve 143 to be communicated with the second outlet, the second stop valve 145 to be in an open state, and the first stop valve 144 to be in a closed state.

[0146] Step 23 includes: controlling the inlet of the second reversing valve 143 to be communicated with the first outlet and the second outlet simultaneously, and the first stop valve 144 and the second stop valve 145 to be in an open state.

[0147] In some embodiments, to save the energy consumption of the cleaning device 1, step 2 of the control method further includes:

[0148] Step 24: When it is indicated that the air pump 13 switches from the spot spraying mode to the general mode in the cleaning mode, control the operating power of the air pump 13 in the general mode to be less than that in the spot spraying mode.

[0149] It should be noted that in the general mode, the user often cleans the dirt with a wet cleaning brush 18 or uses negative pressure suction to recover the dirt, and does not require too much air flow power. While in the spot spraying mode, the user often is used to outputting foam, and rich foam can be generated only when the cleaning liquid and the gas are fully mixed. Therefore, a larger air flow power and a larger gas volume are required. Therefore, the operating power of the air pump 13 in the general mode is set to be less than that in the spot spraying mode.

[0150] In addition, with such a setting, after the user outputs foam by spot spraying, the cleaning liquid crystals can also be rinsed by spot spraying gas and / or clean water, which also requires a larger air flow power and a larger gas volume, and can prevent the first output component 15 from being blocked.

[0151] In some embodiments, when the user uses the cleaning device 1 on a daily basis, the user can use the general mode of the cleaning device 1 to clean dirt with the cleaning brush 18. When the user finds that there is stubborn dirt on the cleaning surface, the user can use the spot spray mode of the cleaning device 1 to spray foam directly on the stubborn dirt to increase the cleaning power, and continue to use the general mode of the cleaning device 1 to clean other areas of the cleaning surface. At this time, the cleaning device 1 needs to switch repeatedly between the general mode and the spot spray mode. Figure 4 and Figure 6 As shown, in different cleaning devices 1, the general mode and the spot spray mode still have some common delivery pipelines (such as the connection component 14). In this way, in order to prevent the residual liquid in the general mode from being output from the spot spray mode, the control method provided by the present application also includes:

[0152] In response to the general mode switching to the spot spray mode and instructing the first output component 15 to output foam, the airflow is controlled to empty the residual liquid in the connecting component 14, and then the connecting component 14 is controlled to be connected to the first output component 15, and the air pump 13 and the cleaning liquid pump 12 are controlled to start outputting foam to the first output component 15.

[0153] It should be noted that, taking the switching of the cleaning device 1 from the general mode to the spot spray mode as an example, the control method includes: controlling the water pump 11 to turn off and disconnect the connecting component 14 and the first output component 15, controlling the air pump 13 to act on the connecting component 14 and empty the liquid in the connecting component 14, and then controlling the connecting component 14 to be connected with the first output component 15, and controlling the cleaning liquid pump 12 and the air pump 13 to act on the first output component 15 together.

[0154] In this way, when the cleaning device 1 switches from the water outlet state of the general mode to the spot spray foam state of the spot spray mode, the control method can control the airflow to empty the residual liquid in the connecting component 14 before the connecting component 14 is connected to the first output component 15, and then control the connecting component 14 to be connected to the first output component 15 after the residual liquid in the connecting component 14 is emptied, and control the air pump 13 and the cleaning liquid pump 12 to start outputting foam to the first output component 15. This setting can prevent the first output component 15 from flowing out the residual liquid in the general mode when outputting foam, thereby improving the user experience. It can be understood that in order to facilitate the emptying of the residual liquid in the pipeline, the airflow can come from the air pump 13 or the dirt suction component, which will not be elaborated in this application.

[0155] In addition, in the switching use of the general mode and the spot spraying mode of the cleaning device 1, the control method also includes:

[0156] In response to the cleaning mode indicating that the first output component 15 stops outputting the cleaning medium, the cleaning liquid pump 12 is controlled to be turned off, and at least one of the water pump 11 and the air pump 13 is controlled to be connected to the second output component 17 to continue running other cleaning modes.

[0157] With such a setting, when the cleaning device 1 switches from the spot spraying mode to the general mode, the first output component 15 stops outputting the cleaning medium. At this time, the cleaning liquid pump 12 stops running, while the water pump 11 and the air pump 13 can be switched to conduct to the second output component 17 to continue running various cleaning modes in the general mode, such as running the clean water mode or the bubble mode, etc. When the cleaning device 1 switches from the general mode to the spot spraying mode, the second output component 17 stops outputting the cleaning medium. At this time, the water pump 11 stops running, and the air pump 13 and the cleaning liquid pump 12 run to drain the residual liquid, and then conduct with the first output component 15 to output foam.

[0158] Understandably, when the cleaning device 1 is in the sewage suction state, the cleaning liquid pump 12, the air pump 13 and the water pump 11 stop running.

[0159] In some embodiments, to enrich the foam output in the spot spraying mode, the cleaning device 1 further includes a foam generator 16 connected between the connection component 14 and the first output component 15. However, the mesh structure in the foam generator 16 will increase the flow resistance of the clean water when spot spraying clean water, resulting in uneven spot spraying of clean water. Thus, the control method further includes: when the cleaning mode indicates that the first output component 15 outputs clean water, controlling both the water pump 11 and the air pump 13 to start and act on the first output component 15 together.

[0160] With such a setting, during the process of the first output component 15 outputting clean water, starting the air pump 13 and the water pump 11 to act on the first output component 15 together can increase the flow force of the clean water by outputting air flow, so as to reduce the resistance influence of the mesh structure in the foam generator 16 on the clean water flow, enable the first output component 15 to ensure the uniformity of water output through the mixture of gas and clean water, and thus improve the user experience.

[0161] Understandably, the "electrically connected" mentioned in this application can be understood as a wired signal connection or a wireless signal connection. The wired signal connection includes wire connection, optical fiber connection or power line communication, etc., and the wireless signal connection includes radio frequency signal, satellite communication, infrared communication, Bluetooth communication, short-range wireless communication technology, etc. This application does not make any restrictions.
