Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and in particular to a control method for cleaning equipment and the cleaning equipment. Background Art

[0002] With the development of science and technology and social progress, more and more families have begun to use cleaning equipment such as vacuum cleaners, fabric cleaning machines, carpet cleaning machines, sweepers or floor scrubbers to improve the efficiency and quality of household hygiene cleaning.

[0003] Generally, a cleaning device is provided with a plurality of nozzles, which can be used to output cleaning media such as cleaning liquid or foam that can dissolve dirt. However, in the related art, the nozzles of the cleaning device are often unable to stably output the cleaning media, resulting in a poor user experience. Summary of the invention

[0004] The present disclosure provides a control method for a cleaning device and a cleaning device, which can enable the cleaning device to stably output a cleaning medium and improve the user experience.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0006] According to a first aspect of an embodiment of the present disclosure, the present disclosure provides a control method for a cleaning device, wherein the cleaning device comprises a conveying component, an output component, and a control device, wherein the conveying component comprises a cleaning liquid conveying component and a non-cleaning liquid conveying component connected to the output component, and the control device is capable of controlling at least one of the conveying components to be in an open state, so that the output component can output a cleaning medium accordingly. The control method comprises: in response to a start operation of the cleaning mode, executing the cleaning mode; in response to a stop instruction of the cleaning mode, when the cleaning mode indicates that the cleaning liquid conveying component is enabled, controlling the cleaning liquid conveying component to be closed, and controlling at least one of the non-cleaning liquid conveying components to be in an open state until the first preset condition is met and then closed. The non-cleaning liquid conveying component is used to convey a medium other than the cleaning liquid.

[0007] According to a second aspect of an embodiment of the present disclosure, the present disclosure provides a control device for a cleaning device, the control device comprising one or more processors for implementing the control method for the cleaning device.

[0008] According to a third aspect of an embodiment of the present disclosure, the present disclosure provides a cleaning device, comprising an output component, a delivery component connected to the output component, and the above-mentioned control device. The delivery component comprises a cleaning liquid delivery component and a non-cleaning liquid delivery component, the control device is electrically connected to the delivery component, and the control device can control at least one of the delivery components to be in an open state, so that the output component can output the cleaning medium accordingly.

[0009] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0010] In the process of executing the cleaning mode of the cleaning device provided by the present disclosure, the output component is used to output the corresponding cleaning medium to clean the dirt. The cleaning liquid delivery component is used to deliver the cleaning liquid to the output component. The non-cleaning liquid delivery component is used to deliver a medium other than the cleaning liquid, such as clean water and / or gas, etc., which is not limited by this application. The control device can control at least one of the cleaning liquid delivery component and the non-cleaning liquid delivery component to be in an open state according to the control instruction, so that the output component can output the cleaning medium accordingly.

[0011] When the cleaning device provided by the present disclosure receives a stop command to stop the cleaning mode during the execution of the cleaning mode, if the delivery component of the cleaning device currently executing the cleaning mode includes a cleaning liquid delivery component, the cleaning liquid delivery component is controlled to stop working, and the non-cleaning liquid delivery component is controlled to continue working to act on the current cleaning liquid delivery path, and the non-cleaning liquid delivery component is turned off after the first preset condition is met. In this way, through the additional operation of the non-cleaning liquid delivery component for a period of time, the cleaning device can use the flow of the non-cleaning liquid to take away the cleaning liquid in the current delivery path, avoid the cleaning liquid from accumulating and crystallizing after drying in the delivery path, and then avoid clogging of the delivery path, so that the cleaning device can stably output the cleaning medium, and improve the operating stability of the cleaning device.

[0012] In addition, the cleaning brush device provided by the present disclosure can be applicable to cleaning equipment such as fabric cleaning machines, carpet cleaning machines or floor scrubbers. The cleaning equipment can automatically switch between various cleaning modes through a control device, or the cleaning equipment can switch between various cleaning modes according to user instructions, and the present disclosure does not limit this.

DETAILED DESCRIPTION

[0025] Here, the technical solutions in the embodiments (or "implementations") of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If there are terms related to directional indications or positional relationships in the embodiments of the present disclosure (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 relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. in the embodiments of the present disclosure are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0027] With the development of science and technology and social progress, more and more families are beginning to use cleaning equipment such as fabric cleaning machines, carpet cleaning machines or floor scrubbers to improve the efficiency and quality of household cleaning. Currently, there are many brands of cleaning equipment available for consumers to choose from on the market. How to win the favor of consumers and improve product competitiveness is an issue that cleaning equipment manufacturers are paying more and more attention to.

[0028] Take a floor scrubber as an example. A floor scrubber is a common cleaning device that can move on the ground and clean the dirt on the ground with a floor brush. For example, a household floor scrubber can be dragged by the user to clean the dirty ground. Usually, there are different degrees of dirt on the ground, including light dirt that is easy to clean, such as dust, hair or sweat stains, as well as stubborn dirt that is difficult to clean, such as oil stains, scale or mold. Therefore, the floor scrubber needs to be able to provide output of a variety of cleaning media (such as clean water, cleaning liquid or foam, etc.) for cleaning to deal with different degrees of dirt. However, in the related art, the nozzle of the floor scrubber used to output the cleaning medium is often blocked due to the crystals formed after the residual drying of the cleaning medium, resulting in the inability of the floor scrubber nozzle to stably output the cleaning medium, and the user experience is poor.

[0029] Based on this, the present disclosure provides a cleaning device that can improve the clogging problem of the nozzle of the cleaning device caused by crystals formed by residual cleaning media, so that the cleaning device can stably output cleaning media, thereby improving the user experience. In addition, the cleaning brush device provided by the present disclosure is not limited to floor scrubbers, but can also be used in a variety of cleaning devices such as fabric cleaning machines or carpet cleaning machines, and the present disclosure does not limit this.

[0030] The cleaning device 1 provided by the present disclosure will be described below with reference to the accompanying drawings.

[0031] See also Figure 1 The present disclosure provides a cleaning device 1, comprising an output component 15, a delivery component connected to the output component 15, and a control device. The delivery component comprises a cleaning liquid delivery component 12 and a non-cleaning liquid delivery component connected to the output component 15, and the control device is electrically connected to the delivery component. The control device can control at least one of the delivery components to be in an open state, so that the output component 15 can output the cleaning medium accordingly.

[0032] It should be noted that the output component 15 is used to output the corresponding cleaning medium to clean the dirt, and the output component 15 may be provided with one or more nozzles, which is not limited by the present disclosure. The cleaning liquid delivery component 12 is used to deliver the cleaning liquid to the output component 15. The non-cleaning liquid delivery component is used to deliver a medium other than the cleaning liquid, such as clean water and / or gas, to the output component 15. The control device can control at least one of the cleaning liquid delivery component 12 and the non-cleaning liquid delivery component to be in an open state according to the control instruction, so that the output component 15 can output the cleaning medium accordingly.

[0033] In this way, when the control device receives a stop command to stop the cleaning mode, the cleaning device 1 provided by the present disclosure can control the cleaning liquid delivery component 12 to stop working if it is detected that the currently working delivery component includes the cleaning liquid delivery component 12, and control the non-cleaning liquid delivery component to continue working to act on the current cleaning liquid delivery path, and the non-cleaning liquid delivery component is turned off after the first preset condition is met. In this way, through the additional operation of the non-cleaning liquid delivery component for a period of time, the cleaning device 1 can use the flow of non-cleaning liquid (such as water flow and / or air flow) to take away the cleaning liquid in the current delivery path, avoid the cleaning liquid from accumulating and crystallizing after drying in the delivery path, and then avoid clogging of the delivery path, so that the cleaning device 1 can stably output the cleaning medium, and improve the operation stability of the cleaning device 1.

[0034] It can be understood that the stop instruction for stopping the cleaning mode can be a signal spontaneously generated by the cleaning device 1. In one example, the stop instruction for stopping the cleaning mode can be a control signal generated according to the execution time. For example, the output time of the cleaning medium is set to 10 seconds. When the control device detects that the output time of the cleaning medium meets 10 seconds, a stop instruction for stopping the cleaning mode is generated. In another example, the stop instruction for stopping the cleaning mode can be a control signal generated according to the cleaning parameters of the cleaning device 1. For example, when the cleaning device 1 detects that the degree of dirtiness changes from severe to mild, a stop instruction for stopping the cleaning mode is generated. In another example, the stop instruction for stopping the cleaning mode can also be a control signal generated by user operation. For example, the user can operate the cleaning button to generate a start instruction for starting the cleaning mode, and the user can generate a stop instruction for stopping the cleaning mode by operating the button again.

[0035] In addition, the non-cleaning liquid delivery component can be turned off after satisfying a first preset condition. The first preset condition may be a preset duration of a built-in delay program of the control device. Of course, the first preset condition may also be a detection state of residual cleaning liquid by the control device. If the residual cleaning liquid state meets the preset requirements, the non-cleaning liquid delivery component is turned off. Of course, the non-cleaning liquid delivery component may also be turned off according to a user input instruction, which is not limited by the present disclosure.

[0036] It is understandable that the start instruction for starting the cleaning mode may also be a signal generated spontaneously by the cleaning device 1 or a control signal generated by the user operating a cleaning button, which will not be elaborated in the present disclosure.

[0037] See also Figure 1 In one embodiment, the non-cleaning liquid delivery component includes a clean water delivery component 11 and / or a gas delivery component 13. In this way, the output component 15 can output a cleaning medium in one or a combination of clean water, cleaning liquid and gas, thereby being able to handle cleaning of different degrees of dirt.

[0038] It is understandable that when the control device only controls the clean water delivery component 11 to be in an open state, the output component 15 can output clean water, and the cleaning device 1 provides a clean water mode. Clean water can be used to wash away light dirt such as dust or sweat stains that are easy to clean. Clean water can be uncontaminated natural water sources such as groundwater or tap water or domestic water. As an example, the clean water delivery component 11 includes a clean water input pipeline connected to the output component 15 and a water pump 111 acting on the clean water input pipeline, and the water pump 111 is electrically connected to the control device.

[0039] When the control device only controls the cleaning liquid delivery component 12 to be in an open state, the output component 15 can output the cleaning liquid, and the cleaning device 1 provides a cleaning liquid mode. The cleaning liquid can be used to clean stubborn dirt such as oil stains, mold or scale. It can be understood that the cleaning liquid includes various cleaning liquids such as oil cleaning liquid, floor cleaning liquid, fabric cleaning liquid, carpet cleaning liquid, glass cleaning liquid, disinfecting cleaning liquid or mildew removal cleaning liquid, and the present disclosure is not limited. As an example, the cleaning liquid delivery component 12 includes a cleaning liquid input pipeline connected to the output component 15 and a cleaning liquid pump 121 acting on the cleaning liquid input pipeline, and the cleaning liquid pump 121 is electrically connected to the control device.

[0040] When the control device only controls the gas delivery component 13 to be in an open state, the output component 15 can output gas, and the cleaning device 1 provides a gas mode. The gas can be a harmless gas such as air or nitrogen, which is not limited by the present disclosure. On the one hand, the gas output by the output component 15 can also be used to blow off the crystals accumulated on the output component 15 after the liquid-containing cleaning medium is dried to prevent the output component 15 from being blocked. On the other hand, the gas can also be used to dry water marks after cleaning or to dry the cleaning brush 17 after cleaning. As an example, the gas delivery component 13 includes a gas input pipeline connected to the output component 15 and an air pump 131 acting on the gas input pipeline, and the air pump 131 is electrically connected to the control device.

[0041] In addition, the control device can also control at least one of the clean water delivery component 11, the cleaning liquid delivery component 12 and the gas delivery component 13 to be in an open state, so that the output component 15 outputs the corresponding cleaning medium. For example, the output component 15 can output any one of the cleaning media of clean water, cleaning liquid and gas, and the output component 15 can also output a mixed liquid of a combination of clean water and cleaning liquid, a bubble water of a combination of clean water and gas, a cleaning liquid foam of a combination of cleaning liquid and gas, a mixed liquid foam of a combination of clean water, cleaning liquid and gas, and the like, which will not be described in detail in this disclosure.

[0042] It is understandable that, compared with the cleaning liquid mode, the cleaning liquid concentration in the mixed liquid in the mixed liquid mode is lower than the cleaning liquid concentration in the cleaning liquid mode, which can save the amount of cleaning liquid. Compared with the water mode, the mixed liquid cleaning mode can improve the cleaning power. In this way, users can choose according to their usage needs, and this disclosure does not limit it.

[0043] In the bubble water mode, the clean water will be dispersed by the impact of gas, so that the clean water can be sprayed evenly to avoid uneven cleaning of dirt and reduce residual water marks.

[0044] Compared with the liquid cleaning mode, the foam mode has weaker fluidity, so the foam can adhere to vertical surfaces or complex surfaces (such as walls or corners), allowing the foam to stay on the dirty surface for a long time, thereby dissolving and cleaning stubborn dirt. In addition, the output component 15 can accumulate a thicker foam layer on the dirty surface to improve the durability of decomposing dirt, thereby improving the cleaning effect. In addition, when the output component 15 outputs foam, the user can also use the foam to draw different patterns to cover the dirt to increase the fun and visual effect of cleaning.

[0045] In this way, the cleaning device 1 provided by the present disclosure can provide a variety of cleaning modes, can improve the cleaning power of the cleaning brush device 10, and enrich the user experience.

[0046] See also Figures 2 to 4 In one embodiment, in order to further enrich the cleaning mode, the output component 15 includes a first output component 151 and a second output component 152. The cleaning device 1 also includes a first reversing valve 14 and a connecting component 18. The first reversing valve 14 is provided with at least three working ports, and the at least three working ports include a first outlet connected to the first output component 151, a second outlet connected to the second output component 152, and an inlet selectively connected between the first outlet and the second outlet. The clean water delivery component 11, the cleaning liquid delivery component 12, and the gas delivery component 13 are respectively connected to the inlet of the first reversing valve 14 through the connecting component 18.

[0047] It should be noted that the connection assembly 18 (not shown in the figure) can be various pipe joints, which are used to connect the input pipelines in each delivery assembly with the inlet of the first reversing valve 14. In addition, the connection assembly 18 can also be a chamber formed by splicing various pipelines or an independent installation part with a cavity, so that at least two of the clean water, cleaning liquid and gas can be pre-mixed before entering the output assembly 15.

[0048] As an example, when the cleaning device 1 includes a gas delivery component 13, a cleaning liquid delivery component 12, and a clean water delivery component 11, the connection component 18 includes a four-way pipe joint. It can be understood that one interface of the four-way pipe joint is connected to the inlet of the first reversing valve 14, and the three delivery components are respectively connected to the remaining three interfaces of the four-way pipe joint in a one-to-one correspondence.

[0049] As another example, when the cleaning device 1 includes a gas delivery component 13, a cleaning liquid delivery component 12, and a clean water delivery component 11, the connection component 18 includes two interconnected three-way pipe joints. It can be understood that one interface of the first three-way pipe joint is connected to the inlet of the first reversing valve 14, one interface of the second three-way pipe joint and one of the three delivery components are respectively connected to the remaining two interfaces of the first three-way pipe joint, and the remaining two of the three delivery components are respectively connected to the remaining two interfaces of the second three-way pipe joint. For example, the clean water delivery component 11 is connected to the first three-way pipe joint, and the cleaning liquid delivery component 12 and the gas delivery component 13 are respectively connected to the second three-way joint.

[0050] In this way, the connection component 18 can facilitate the connection of the input pipeline of each conveying component with the inlet of the first reversing valve 14. When the inlet of the first reversing valve 14 is connected to the first outlet, at least one of the clean water conveying component 11, the cleaning liquid conveying component 12 and the gas conveying component 13 is in an open state, so that the first output component 151 can output one or a combination of clean water, cleaning liquid and gas to correspond to various cleaning modes of the cleaning device 1. When the inlet of the first reversing valve 14 is connected to the second outlet, at least one of the clean water conveying component 11, the cleaning liquid conveying component 12 and the gas conveying component 13 is in an open state, so that the second output component 152 can output one or a combination of clean water, cleaning liquid and gas to correspond to various cleaning modes of the cleaning device 1. In this way, the cleaning device 1 can have multiple cleaning modes, and the cleaning medium in the input pipeline of each conveying component can be pre-mixed and then connected to each conveying component through the first reversing valve 14 through the connection component 18. Of course, it is understandable that the first output component 151 and the second output component 152 can output the cleaning medium at the same time. In this case, the inlet of the first reversing valve 14 is connected to the first outlet and the second outlet, which is not elaborated in the present disclosure.

[0051] In addition, it should be noted that the clean water delivery component 11 is usually a common pipeline of the cleaning device 1. Connecting the input pipeline of the clean water delivery component 11 and the inlet of the first reversing valve 14 to the same three-way pipe joint can relatively shorten the flow path of the clean water flowing to each output component 15, thereby facilitating the output of the clean water. In addition, when the input pipeline of the cleaning liquid delivery component 12 and the input pipeline of the gas delivery component 13 need to be repaired and replaced, the two three-way pipe joints can be directly disassembled, and the empty interface of the three-way pipe joint where the clean water input pipeline is located can be covered and sealed, which will not affect the output of clean water by the cleaning device 1.

[0052] It can be understood that there is no restriction on the diameter of the input pipeline of each conveying component, and the connecting component 18 can set the size of the interface according to the diameter of each pipeline.

[0053] See also Figures 2 to 4 In another embodiment, in order to further enrich the cleaning mode, the output assembly 15 includes a first output assembly 151 and a second output assembly 152. The cleaning device 1 also includes a second reversing valve 14, a first connecting member 181 and a second connecting member 182. The second reversing valve 14 is provided with at least three working ports, and the at least three working ports include a first outlet connected to the first connecting member 181, a second outlet connected to the second connecting member 182, and an inlet selected to be connected between the first outlet and the second outlet. The cleaning liquid delivery assembly 12 is connected to the inlet of the second reversing valve 14, the first output assembly 151 and the clean water delivery assembly 11 are respectively connected to the first connecting member 181, and the second output assembly 152 and the gas delivery assembly 13 are respectively connected to the second connecting member 182.

[0054] It should be noted that, unlike the above-mentioned embodiment, the cleaning liquid delivery component 12 is connected to the inlet of the second reversing valve 14, the clean water delivery component 11 and the first output component 151 are connected to the first outlet of the second reversing valve 14 via the first connecting member 181, and the gas delivery component 13 and the second output component 152 are connected to the second outlet of the second reversing valve 14 via the second connecting member 182. In this way, the cleaning liquid delivery component 12 can be controlled to be connected to the first output component 151 or the second output component 152 through the second reversing valve 14, so that the first output component 151 and the second output component 152 can output the cleaning medium containing the cleaning liquid respectively. The clean water delivery component 11 can be directly connected to the first output component 151, and the gas delivery component 13 can be directly connected to the second output component 152.

[0055] In this way, when the inlet of the second reversing valve 14 is connected to the first outlet, if at least one of the clean water delivery component 11 and the cleaning liquid delivery component 12 is in an open state, the first output component 151 can output one of clean water, cleaning liquid, and a mixture of clean water and cleaning liquid. When the inlet of the second reversing valve 14 is connected to the second outlet, if at least one of the gas delivery component 13 and the cleaning liquid delivery component 12 is in an open state, the second output component 152 can output one of cleaning liquid, gas, and a foam mixed with cleaning liquid and gas. In this way, the first output component 151 and the second output component 152 can output different cleaning media respectively, and further combine to form different cleaning modes, enriching the cleaning modes of the cleaning device 1.

[0056] Of course, it is understandable that the first output assembly 151 and the second output assembly 152 can be used at the same time, and the present disclosure does not limit it. For example, when the inlet of the second reversing valve 14 is connected to the first outlet, at least one of the clean water delivery assembly 11 and the cleaning liquid delivery assembly 12 is in an open state, then the gas delivery assembly 13 can be opened or closed independently, so that when the first output assembly 151 outputs at least one of clean water and cleaning liquid, the second output assembly 152 can also output gas. Correspondingly, when the inlet of the second reversing valve 14 is connected to the second outlet, at least one of the gas delivery assembly 13 and the cleaning liquid delivery assembly 12 is in an open state, then the clean water delivery assembly 11 can be opened or closed independently, so that when the second output assembly 152 outputs at least one of gas and cleaning liquid, the first output assembly 151 can also output clean water.

[0057] In addition, the first connector 181 (not shown in the figure) and the second connector 182 (not shown in the figure) can be three-way pipe joints. The first connector 181 can pre-mix the clean water and the cleaning liquid to form a mixed liquid before entering the first input component. The second connector 182 can pre-mix the cleaning liquid and the gas to generate foam before entering the second output component 152.

[0058] In addition, when the inlet of the second reversing valve 14 is connected to the first outlet and the second outlet respectively, if the cleaning liquid delivery component 12 is in a closed state, the gas delivery component 13 can not only be connected to the second output component 152, but also be connected to the first output component 151, so as to blow off the crystals of the liquid cleaning medium on the first output component 151 and the second output component 152 after drying through the gas mode, so as to avoid blockage of the first output component 151 and the second output component 152.

[0059] In some embodiments, when the cleaning device 1 also includes a clean water delivery component 11, if the cleaning device 1 stops the cleaning mode, in addition to extending the gas mode and using the gas delivery component 13 to blow off the crystals, the cleaning device 1 can also extend the clean water mode and use clean water to blow away the crystals to avoid blockage of each output component 15, which is not limited by the present disclosure.

[0060] See also Figures 2 to 4 In order to facilitate the cleaning device 1 to have daily cleaning functions and fixed-point cleaning functions, the cleaning device 1 also includes a housing component 16 and a cleaning brush 17 installed on the housing component 16, and the cleaning brush 17 is used to perform a cleaning operation on the surface to be cleaned. Among them, the first output component 151 is arranged toward the cleaning brush 17, and the second output component 152 is arranged toward the surface to be cleaned.

[0061] It should be noted that the surface to be cleaned includes the floor, kitchen countertop or carpet, etc. The cleaning brush 17 is used to clean the floor, kitchen countertop or carpet, etc. The first output component 151 is arranged toward the cleaning brush 17 , and the cleaning medium output by the first output component 151 can be output to the cleaning brush 17 .

[0062] It can be understood that the first output component 151 can correspond to outputting any one or a combination of cleaning media in the state of clean water, cleaning liquid and gas. When the first output component 151 outputs clean water, in the cleaning operation state, the cleaning brush 17 can be soaked with clean water to clean the light dirt on the floor or carpet to be cleaned. Alternatively, the clean water output by the first output component 151 can also self-clean the cleaning brush 17 to rinse the dirt on the cleaning brush 17. Alternatively, when the first output component 151 outputs a cleaning medium containing cleaning liquid to the cleaning brush 17, the cleaning force of the cleaning brush 17 on the surface to be cleaned and the cleaning force of the cleaning brush 17 itself can be increased. Alternatively, when the first output component 151 outputs gas, in addition to being able to blow off the crystals on the first output component 151 to avoid clogging of the first output component 151, the cleaning brush 17 can also be dried by blowing the cleaning brush 17 with gas. In addition, a heating component can also be provided between the gas delivery component 13 and the output component 15, and the heating component and the gas delivery component 13 work simultaneously to improve the drying efficiency and drying effect.

[0063] It is understandable that the cleaning brush 17 is usually located at the bottom of the shell assembly 16. In order to facilitate the second output component 152 to output the cleaning medium to the surface to be cleaned, the second output component 152 can be set higher than the cleaning brush 17, and the second output component 152 can be tilted toward the bottom of the front of the shell assembly 16, so that the second output component 152 can directly output the cleaning medium to the dirt on the surface to be cleaned, so as to perform point cleaning of the dirt, thereby improving the cleaning effect. Correspondingly, the second output component 152 can also correspond to outputting any one or a combination of cleaning media such as clean water, cleaning liquid and gas, so as to directly perform point spraying on dirt of different degrees, which is not elaborated in this disclosure. Of course, when the second output component 152 outputs the cleaning medium to the dirt at a fixed point, the output amount of the cleaning medium can be quantitatively set according to user needs, and this disclosure does not limit it.

[0064] See also Figures 2 to 4 In some embodiments, the first output assembly 151 includes a liquid spray plate mounted on the housing assembly 16, and the liquid spray plate is arranged along the length direction of the cleaning brush 17 and is provided with a plurality of nozzles. It can be understood that the plurality of nozzles of the liquid spray plate can be arranged along the length direction of the cleaning brush 17 so that the output cleaning medium can be in uniform contact with the cleaning brush 17. Alternatively, the liquid spray plate can also be provided with a strip-shaped nozzle extending along the length direction of the cleaning brush 17, which is not limited in the present disclosure.

[0065] See also Figures 2 to 4 In some embodiments, the second output assembly 152 includes a nozzle mounted on the housing assembly 16. It should be noted that the nozzle can be used to directly spray dirt to output the cleaning medium in a fixed point and / or quantitative manner. The spray range and spray strength of the nozzle can be adjusted according to user needs, and this disclosure does not set it.

[0066] In some embodiments, the cleaning device 1 also includes a foam generator 19 (not shown in the figure), and the foam generator 19 is connected between the first output component 151 and the first outlet and / or the foam generator 19 is connected between the second output component 152 and the second outlet, or the foam generator 19 is integrated with one of the first output component 151 and the second output component 152, which is not limited in the present disclosure.

[0067] As an example, the second output component 152 includes a nozzle, and the nozzle may be built with a foam generator 19, so that the cleaning liquid and gas first pass through the foam generator 19 to generate rich foam and then spray out through the nozzle. In this way, the foam generator 19 can enrich the amount of foam generated, so as to enrich the foam and save the connecting pipeline between the nozzle and the foam generator 19. Of course, the nozzle and the foam generator 19 can also be set independently of each other and then connected by a pipeline, which is not limited by the present disclosure.

[0068] In some embodiments, the first output assembly 151 and the second output assembly 152 may be fixedly connected or rotatably connected to the housing assembly 16 , respectively, to adjust the output angle of the cleaning medium, which is not limited in the present disclosure.

[0069] In addition, see Figure 2 and Figure 4 , Figure 2 FIG. 1 is a schematic structural diagram of a cleaning brush device 10 having two output assemblies 15 according to an embodiment. Figure 3 for Figure 2 A schematic diagram of the internal structure of the cleaning brush device 10 is shown. Figure 4 for Figure 2 Another schematic diagram of the internal structure of the cleaning brush device 10 is shown. The housing component 16 is provided with a receiving cavity, and the gas delivery component 13, the cleaning liquid delivery component 12 and the clean water delivery component 11 of the cleaning device 1 can be installed in the receiving cavity of the housing component 16. The installation position of each delivery component in the housing component 16 is not limited to Figure 2 and Figure 3 For the arrangement structure shown, the manufacturer can also adjust the installation position of each input pipe in the shell assembly 16 according to the actual assembly situation to form other arrangement structures, which is not limited by the present disclosure.

[0070] See also Figure 3 In some embodiments, when the cleaning device 1 is assembled, the cleaning brush 17 is installed on the housing assembly 16, and the clean water delivery assembly 11, the cleaning liquid delivery assembly 12, and the gas delivery assembly 13 are respectively arranged on the housing assembly 16. Among them, each delivery assembly is arranged at intervals along the length direction of the housing assembly 16, and then each delivery assembly is respectively connected to the connecting assembly 18. This layout method can facilitate the connection between the connecting assembly 18 and each delivery assembly, so that the structure between the connecting assembly 18 and each delivery assembly is compact, which is conducive to the miniaturization of the cleaning device 1, thereby reducing the occupied space of the cleaning device 1.

[0071] At the same time, the clean water delivery component 11 and the cleaning liquid delivery component 12 can be symmetrically arranged in the housing component 16. In this way, the two larger components, the clean water delivery component 11 and the cleaning liquid delivery component 12, are arranged staggered with each other, and the respective sizes of the clean water delivery component 11 and the cleaning liquid delivery component 12 can be increased, and the respective capacities of the clean water delivery component 11 and the cleaning liquid delivery component 12 can be increased. In addition, such a layout method can also integrate more structures in the cleaning device 1 of the same size, so that the cleaning device 1 has more functions and improves the user experience.

[0072] The cleaning device 1 provided in the present disclosure includes a floor scrubber, a sweeping robot, a vacuum cleaner, a carpet cleaning machine or a fabric cleaning machine, etc., and the present disclosure does not make any limitation thereto.

[0073] See also Figure 5In some embodiments, the cleaning device 1 takes a floor scrubber as an example, and the cleaning device 1 also includes a main device 20, a cleaning brush device 10, a clean water tank 30, a cleaning liquid tank 40, and a control device. The cleaning brush device 10 serves as a floor brush assembly, and the main device 20 serves as a handle device. The main device 20 and the cleaning brush device 10 are detachably connected. The clean water tank 30 is connected to the clean water delivery assembly 11, and the cleaning liquid tank 40 is connected to the cleaning liquid delivery assembly 12. Each delivery assembly can be installed on the main device 20 or the cleaning brush device 10, and the present disclosure does not limit it. The control device is installed on the main device 20 and / or the cleaning brush device 10, and the control device is electrically connected to the reversing valve 14 and each delivery assembly respectively.

[0074] It should be noted that the main device 20 may include a handle assembly detachably connected to the cleaning brush device 10. The clean water tank 30 may be mounted on the handle assembly so that the user can remove and add clean water. Of course, the clean water tank 30 may also be mounted on the housing assembly 16 of the cleaning brush device 10, which is not limited in the present disclosure. In addition, the cleaning liquid tank 40 may be mounted on the cleaning brush device 10.

[0075] The control device can be used to set the cleaning program, so that the reversing valve 14 can automatically switch to various cleaning modes according to the set cleaning program to improve the intelligence of the device. The control device can also be used to customize the cleaning mode, so that the reversing valve 14 can switch to various cleaning modes according to the user input instructions to adapt to the user's various usage needs.

[0076] As an example, the control device includes an operation button installed on the main device 20 and a controller electrically connected to the operation button, and the controller is electrically connected to the reversing valve 14 to switch the conduction state of the reversing valve 14 through the operation button. Of course, the controller can also be electrically connected to a mobile device such as a mobile phone, a computer or a tablet, so that the user can switch various cleaning modes through the corresponding application software or application program in the mobile device such as a mobile phone, a computer or a tablet.

[0077] As an example, the cleaning device 1 further includes a dirt detection device, which is electrically connected to the control device to switch the conduction state of the reversing valve 14 according to the degree of dirt detected by the dirt detection device. It can be understood that the dirt detection device includes a camera component, a photoelectric sensor component, or an electrostatic adsorption detection component, etc., which is not limited in the present disclosure.

[0078] In addition, the cleaning device 1 provided in the present disclosure may also be provided with a dirt box for collecting dirt processed by the cleaning device 1. The dirt box may be provided in the main device 20 or in the cleaning brush device 10, and the present disclosure does not limit this.

[0079] It can be understood that the cleaning device 1 in the above embodiment is described by taking the output components 15 as an example, that is, the output component 15 includes a first output component 151 and a second output component 152. In other embodiments, the output components 15 of the cleaning device 1 can also be provided with only 1, 3, 4 or 5, or any number required by the user, which is not limited by the present disclosure.

[0080] In addition to the above-mentioned cleaning device 1, the present disclosure also provides a control method of the cleaning device 1. The control method of the cleaning device 1 provided by the present disclosure will be described below.

[0081] Step 1: In response to a start-up operation of a cleaning mode, the cleaning mode is executed.

[0082] Step 2: When the control device receives a stop instruction of the cleaning device 1 to stop the cleaning mode, the control device correspondingly closes the corresponding conveying component so that the corresponding output component 15 stops conveying the cleaning medium in one or a combination of cleaning liquid and gas.

[0083] It should be noted that the cleaning equipment 1 includes an output component 15, a conveying component connected to the output component 15, and a control device electrically connected to the conveying component. The conveying component includes a cleaning liquid conveying component 12 and a non-cleaning liquid conveying component. The control device can control at least one of the conveying components to be in an open state, so that the output component 15 can output the cleaning medium accordingly.

[0084] The control device can obtain control information, which includes a start instruction for starting the cleaning mode and a stop instruction for stopping the cleaning mode, so as to control the start and stop of the cleaning device 1. When the cleaning device 1 is started, the control device responds to the start instruction to start the corresponding conveying component, so that the corresponding output component 15 can output the cleaning medium. When the cleaning device 1 is shut down, the control device responds to the stop instruction to shut down the corresponding conveying component, so that the corresponding output component 15 can stop outputting the cleaning medium.

[0085] In some embodiments, to avoid clogging of the output assembly 15, step 2 of the control method further includes:

[0086] Step 21: In response to the stop instruction of the cleaning mode, when the cleaning mode indicates to enable the cleaning liquid delivery component 12, the cleaning liquid delivery component 12 is controlled to be closed, and the non-cleaning liquid delivery component is controlled to be in an open state until the first preset condition is met and then closed.

[0087] It should be noted that the non-cleaning liquid delivery component is used to deliver a medium other than the cleaning liquid. As an example, the non-cleaning liquid delivery component may include a clean water delivery component and / or a gas delivery component.

[0088] In this way, the control method of the cleaning device 1 provided by the present disclosure can control the cleaning liquid delivery component 12 to stop working when the control device receives a stop command to stop the cleaning mode, if it is detected that the currently working delivery component includes the cleaning liquid delivery component 12, and control the non-cleaning liquid delivery component to continue working to act on the current cleaning liquid delivery path, and the non-cleaning liquid delivery component is turned off after the first preset condition is met. In this way, through the additional operation of the non-cleaning liquid delivery component for a period of time, the cleaning device 1 can use the flow of non-cleaning liquid (such as water flow and / or air flow) to take away the cleaning liquid in the current delivery path, avoid the cleaning liquid from accumulating and crystallizing after drying in the delivery path, and then avoid clogging of the delivery path, so that the cleaning device 1 can stably output the cleaning medium, and improve the operation stability of the cleaning device 1.

[0089] In some embodiments, the first preset condition includes at least one of the following:

[0090] (1) The control device has a built-in delay program, and the control device controls the non-cleaning liquid delivery component to close according to the delay program.

[0091] (2) The cleaning device 1 also includes a detection device for detecting the state of residual cleaning liquid in the output component 15, and the detection device is electrically connected to the control device. If the state of residual cleaning liquid measured by the detection device meets the requirements, the detection device sends a shutdown signal to the control device, and the control device controls the non-cleaning liquid delivery component to be closed according to the shutdown signal.

[0092] (3) The cleaning device 1 further comprises an operation button electrically connected to the control device, and the control device controls the non-cleaning liquid delivery component to be closed according to an input instruction of the operation button.

[0093] It should be noted that the stop instruction for stopping the cleaning mode may be a signal spontaneously generated by the cleaning device 1. In one example, the stop instruction for stopping the cleaning mode may be a control signal generated according to the execution time. For example, the output time of the cleaning medium is set to 10 seconds. When the control device detects that the output time of the cleaning medium meets 10 seconds, a stop instruction for stopping the cleaning mode is generated. In another example, the stop instruction for stopping the cleaning mode may be a control signal generated according to the cleaning parameters of the cleaning device 1. For example, when the cleaning device 1 detects that the degree of dirtiness changes from severe to mild, a stop instruction for stopping the cleaning mode is generated. In yet another example, the stop instruction for stopping the cleaning mode may also be a control signal generated by a user operation. For example, a user may operate a cleaning button to generate a start instruction for starting the cleaning mode, and a stop instruction for stopping the cleaning mode may be generated when the user operates the button again.

[0094] In addition, the non-cleaning liquid delivery component can be turned off after satisfying a first preset condition. The first preset condition may be a preset duration of a built-in delay program of the control device. Of course, the first preset condition may also be a detection state of residual cleaning liquid by the control device. If the residual cleaning liquid state meets the preset requirements, the non-cleaning liquid delivery component is turned off. Of course, the non-cleaning liquid delivery component may also be turned off according to a user input instruction, which is not limited by the present disclosure.

[0095] It can be understood that when the non-cleaning liquid delivery component includes both the clean water delivery component 11 and the gas delivery component 13, if the cleaning device 1 stops the cleaning mode, the cleaning device 1 can first extend the clean water mode and then extend the gas mode. In this way, the cleaning device 1 can first flush the cleaning liquid in the output path with clean water, and then blow off the crystals with gas, thereby achieving double cleaning of the output component 15 to avoid output blockage.

[0096] In some embodiments, in order to enrich the cleaning modes of the cleaning device 1, the delivery component of the cleaning device 1 includes a clean water delivery component 11, a cleaning liquid delivery component 12 and a gas delivery component 13. Accordingly, the cleaning mode of the cleaning device 1 includes at least one of a clean water cleaning mode, a cleaning liquid cleaning mode, a gas cleaning mode, a foam cleaning mode, a mixed liquid cleaning mode, and a bubble water cleaning mode. Step 1 of the control method also includes at least one of the following:

[0097] Step 101: When the cleaning mode includes the clean water cleaning mode, the clean water delivery component 11 is controlled to be in an open state, and the cleaning liquid delivery component 12 and the gas delivery component 13 are controlled to be in a closed state respectively.

[0098] Step 102: When the cleaning mode includes the cleaning liquid mode, the cleaning liquid delivery component 12 is controlled to be in an open state, and the gas delivery component 13 and the clean water delivery component 11 are controlled to be in a closed state respectively.

[0099] Step 103: When the cleaning mode includes the gas mode, the gas delivery component 13 is controlled to be in an open state, and the clean water delivery component 11 and the cleaning liquid delivery component 12 are controlled to be in a closed state respectively.

[0100] Step 104: When the cleaning mode includes the foam mode, the cleaning liquid delivery component 12 and the gas delivery component 13 are controlled to be in the open state, and the clean water delivery component 11 is controlled to be in the closed state.

[0101] Step 105: When the cleaning mode includes the mixed liquid mode, the clean water delivery component 11 and the cleaning liquid delivery component 12 are controlled to be in an open state, and the gas delivery component 13 is controlled to be in a closed state.

[0102] Step 106: When the cleaning mode includes the bubble water mode, the clean water delivery component 11 and the gas delivery component 13 are controlled to be in the open state, and the cleaning liquid delivery component 12 is controlled to be in the closed state.

[0103] It should be noted that the output component 15 can output one or a combination of clean water, cleaning liquid and gas to clean different degrees of dirt. In addition, the use order of various cleaning modes of the cleaning device 1 is not limited by the present disclosure, and users can choose according to actual needs.

[0104] See also Figure 6 In some embodiments, in order to further enrich the cleaning modes of the cleaning device 1, the cleaning device 1 also has daily cleaning functions and fixed-point cleaning functions. Specifically, the output component 15 of the cleaning device 1 includes a first output component 151 and a second output component 152. The cleaning device 1 also includes a first reversing valve 14 and a connecting component 18. The first reversing valve 14 is provided with at least three working ports. The at least three working ports include a first outlet connected to the first output component 151, a second outlet connected to the second output component 152, and an inlet selected to be connected between the first outlet and the second outlet. The clean water delivery component 11, the cleaning liquid delivery component 12, and the gas delivery component 13 are respectively connected to the inlet of the first reversing valve 14 through the connecting component 18. In this way, step 1 of the control method also includes at least one of the following:

[0105] Step 11a: When the cleaning mode indicates that the first output component 151 outputs the cleaning medium, the inlet and the first outlet of the first reversing valve 14 are controlled to be connected, and each conveying component is controlled to be in an open state accordingly, so that the cleaning medium output by the first output component 151 includes one or a combination of clean water, cleaning liquid and gas.

[0106] Step 12a: When the cleaning mode indicates that the second output component 152 outputs the cleaning medium, the inlet of the first reversing valve 14 is controlled to be connected to the second outlet, and each conveying component is controlled to be in an open state accordingly, so that the cleaning medium output by the second output component 152 includes one or a combination of clean water, cleaning liquid and gas.

[0107] Step 13a: When the cleaning mode indicates that the first output component 151 and the second output component 152 output cleaning media respectively, the inlet of the first reversing valve 14 is controlled to be connected to the first outlet and the second outlet, and each conveying component is controlled to be in an open state accordingly, so that the cleaning media output by the first output component 151 and the second output component 152 include one or a combination of clean water, cleaning liquid and gas.

[0108] It should be noted that the cleaning device 1 further includes a housing assembly 16 and a cleaning brush 17 mounted on the housing assembly 16, and the cleaning brush 17 is used to perform a cleaning operation on the surface to be cleaned. The first output assembly 151 can be arranged toward the cleaning brush 17, and the second output assembly 152 can be arranged toward the surface to be cleaned.

[0109] It can be understood that when the cleaning device 1 is in the daily cleaning mode, the inlet of the first reversing valve 14 can be connected to the first outlet, so that the first output component 151 can output the cleaning medium to the cleaning brush 17. At this time, the control device can control at least one of the clean water delivery component 11, the cleaning liquid delivery component 12 and the gas delivery component 13 to be in an open state, so that the first output component 151 can output one or a combination of clean water, cleaning liquid and gas to the cleaning brush 17.

[0110] When the cleaning device 1 is in the fixed-point cleaning mode, the inlet of the first reversing valve 14 can be connected to the second outlet, so that the second output component 152 can output the cleaning medium to the surface to be cleaned. At this time, the control device can control at least one of the clean water delivery component 11, the cleaning liquid delivery component 12 and the gas delivery component 13 to be in an open state, so that the second output component 152 can output one or a combination of clean water, cleaning liquid and gas to the surface to be cleaned.

[0111] In addition, the daily cleaning mode and the fixed-point cleaning mode of the cleaning device 1 can be used simultaneously, and the inlet of the first reversing valve 14 can be connected to both the first outlet and the second outlet. In this way, the first output component 151 and the second output component 152 can output the cleaning medium simultaneously.

[0112] As an example, the first reversing valve 14 may be a two-position three-way valve or a three-position three-way valve, which is not limited in the present disclosure.

[0113] See also Figure 6 Taking the first reversing valve 14 as a two-position three-way valve as an example, the output of various cleaning media by the cleaning device 1 in accordance with the corresponding cleaning modes is described.

[0114] It should be noted that the clean water delivery assembly 11 includes a clean water input pipeline connected to the connecting assembly 18 and a water pump 111 acting on the clean water input pipeline. The cleaning liquid delivery assembly 12 includes a clean liquid input pipeline connected to the connecting assembly 18 and a clean liquid pump 121 acting on the clean liquid input pipeline. The gas delivery assembly 13 includes a gas input pipeline connected to the connecting assembly 18 and an air pump 131 acting on the gas input pipeline. The clean liquid input pipeline is connected to the clean liquid tank 40, and the clean water input pipeline is connected to the clean water tank 30. The inlet of the first reversing valve 14 is connected to the connecting assembly 18, the first outlet of the first reversing valve 14 is connected to the first output assembly 151, and the second outlet of the first reversing valve 14 is connected to the second output assembly 152. The control device can be electrically connected to the water pump 111, the clean liquid pump 121, the air pump 131 and the first reversing valve 14.

[0115] In the daily cleaning mode of the cleaning device 1, the control device controls the inlet of the first reversing valve 14 to be connected to the first outlet and disconnected from the second outlet. At this time, the first output component 151 can output the cleaning medium to the cleaning brush 17, and the cleaning device 1 can use the cleaning brush 17 to clean the dirt. The control device can also control at least one of the water pump 111, the cleaning liquid pump 121 and the air pump 131 to start or stop, so that the first output component 151 can output one or a combination of clean water, cleaning liquid and gas.

[0116] Specifically, in the daily cleaning mode of the cleaning device 1, if only the water pump 111 of the cleaning device 1 is started, and the cleaning liquid pump 121 and the air pump 131 are turned off, the first output component 151 can output clean water to the cleaning brush 17, 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 17 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 17 of the cleaning device 1 itself to wash away the dirt on the cleaning brush 17. 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 first output component 151 to prevent the formation of crystals after the cleaning medium containing the cleaning liquid dries, thereby avoiding clogging of the first output component 151.

[0117] If only the cleaning liquid pump 121 of the cleaning device 1 is started, and the water pump 111 and the air pump 131 are turned off, the first output component 151 can output cleaning liquid to the cleaning brush 17, and the cleaning brush 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 17. Usually, 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.

[0118] If the water pump 111 and the cleaning liquid pump 121 of the cleaning device 1 are both started, and the air pump 131 is turned off, the first output component 151 can output the mixed liquid to the cleaning brush 17, 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 the concentration of the cleaning liquid in the cleaning liquid mode. It is equivalent to that the cleaning liquid is diluted with clean water to form a mixed liquid. The cleaning power of the mixed liquid cleaning mode is higher than that of the clean water mode and lower than that of the cleaning liquid mode. Users can choose to use the mixed liquid cleaning mode according to the degree of dirtiness or customized usage requirements, and the present disclosure does not limit it. In addition, through the mixed liquid cleaning mode, the cleaning power can be improved compared with the clean water mode, and the amount of cleaning liquid can be saved compared with the cleaning liquid mode.

[0119] If the water pump 111 and the air pump 131 of the cleaning device 1 are started, and the cleaning liquid pump 121 is turned off, the first output component 151 can evenly output bubble water to the cleaning brush 17, and the cleaning device 1 is in the bubble water mode. It can be understood that the bubble water mode allows the clean water to be sprayed evenly, which can avoid uneven cleaning of dirt and reduce residual water marks. The present disclosure does not limit the size of the water droplets in the bubble water.

[0120] If the cleaning device 1 has the cleaning liquid pump 121 and the air pump 131 started, and the water pump 111 is turned off, the first output component 151 can output the cleaning liquid foam to the cleaning brush 17. If the cleaning device 1 has the water pump 111, the cleaning liquid pump 121 and the air pump 131 started, the first output component 151 can output the mixed liquid foam to the cleaning brush 17. The cleaning device 1 is in foam mode. It can be understood that the concentration of cleaning liquid in the cleaning liquid foam is higher than the concentration of cleaning liquid in the mixed liquid foam. The user can choose to output the cleaning liquid foam or the mixed liquid foam according to the degree of dirtiness, and the present disclosure is not limited. Compared with liquid, the fluidity of the foam is weaker, so the foam can adhere to vertical surfaces or complex surfaces (such as walls or corners), so that the foam can stay on the dirty surface for a long time, and then dissolve and clean the stubborn dirt. In addition, the output component 15 can accumulate a thicker foam layer on the dirty surface to improve the durability of decomposing dirt, thereby improving the cleaning effect. In addition, when the first output component 151 outputs foam, the user can also use the foam to draw different patterns to cover the dirt to enhance the cleaning interest and visual effect.

[0121] If the air pump 131 of the cleaning device 1 is started, and the cleaning liquid pump 121 and the water pump 111 are turned off, the first output component 151 can output gas to the cleaning brush 17, and the cleaning device 1 is in the gas mode, which is used to blow dry the cleaning brush 17, that is, after the cleaning device 1 has finished cleaning the used cleaning brush 17, it can also blow dry the cleaning brush 17 through the gas blown out by the first output component 151 to prevent the cleaning brush 17 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 first output component 151 dries, to prevent the first output component 151 from being blocked. Alternatively, the gas mode can also be used to dry the cleaning water marks remaining on the ground or carpet waiting to be cleaned, so as to dry the ground or carpet waiting to be cleaned, and achieve instant mopping and drying. It can be understood that the output gas can be air or harmless gas such as nitrogen.

[0122] Figure 6 The cleaning device 1 shown also has a fixed-point cleaning function. In the fixed-point cleaning mode of the cleaning device 1, the control device controls the inlet of the first reversing valve 14 to be connected to the second outlet and disconnected from the first outlet. At this time, the second output component 152 can directly spray the dirty fixed point on the surface to be cleaned. Of course, when the cleaning medium is output to the dirty fixed point, the output amount of the cleaning medium can be quantitatively set according to user needs, and the present disclosure does not limit it.

[0123] Specifically, in the fixed-point cleaning mode of the cleaning device 1, at least one of the water pump 111, the cleaning liquid pump 121 and the air pump 131 can be started separately, so that the second output component 152 can output clean water, cleaning liquid, gas, mixed liquid, foam or bubble water accordingly, thereby enabling the second output component 152 to switch various cleaning modes, which will not be elaborated in this disclosure.

[0124] Furthermore, in other embodiments, Figure 6 The first reversing valve 14 shown can also be a three-position three-way valve. Figure 6 In the middle position of the first reversing valve 14 shown, the inlet of the first reversing valve 14 can be connected to both the first outlet and the second outlet, so that the first output component 151 and the second output component 152 can be used at the same time. In this way, the first output component 151 and the second output component 152 of the cleaning device 1 can output clean water, cleaning liquid, gas, mixed liquid, foam or bubble water at the same time. In this way, the cleaning device 1 can use the cleaning brush 17 to clean the dirt, and can also directly spray the cleaning medium on the dirt on the ground or carpet to be cleaned during the cleaning process to improve the cleaning strength.

[0125] certainly, Figure 6 The first reversing valve 14 shown may also be a four-way valve or a five-way valve, etc., and the first reversing valve 14 is provided with several working positions, which the manufacturer may set according to user requirements, and the present disclosure does not impose any limitation thereto.

[0126] See also Figure 7 , in some embodiments, with Figure 6 The cleaning device 1 shown is different in that the cleaning device 1 also includes a second reversing valve 14, a first connecting member 181 and a second connecting member 182. The second reversing valve 14 is provided with at least three working ports, and the at least three working ports include a first outlet connected to the first connecting member 181, a second outlet connected to the second connecting member 182, and an inlet selected to be connected between the first outlet and the second outlet. The cleaning liquid delivery component 12 is connected to the inlet of the second reversing valve 14, the first output component 151 and the clean water delivery component 11 are respectively connected to the first connecting member 181, the second output component 152 and the gas delivery component 13 are respectively connected to the second connecting member 182, and step 1 of the control method also includes at least one of the following:

[0127] Step 11b: When the cleaning mode indicates that the first output component 151 outputs the cleaning medium, the inlet of the second reversing valve 14 is controlled to be connected to the first outlet, and at least one of the clean water delivery component 11 and the cleaning liquid delivery component 12 is controlled to be in an open state, so that the cleaning medium output by the first output component 151 includes one of clean water, cleaning liquid and mixed liquid.

[0128] Step 12b: When the cleaning mode indicates that the second output component 152 outputs the cleaning medium, the inlet of the second reversing valve 14 is controlled to be connected to the second outlet, and at least one of the cleaning liquid delivery component 12 and the gas delivery component 13 is controlled to be in an open state, so that the cleaning medium output by the second output component 152 includes one of cleaning liquid, foam and gas.

[0129] See also Figure 7 In some embodiments, the first output component 151 and the second output component 152 of the cleaning device 1 can be used in combination, that is, the cleaning mode indicates that the first output component 151 and the second output component 152 output the cleaning medium in combination. Step 1 of the control method also includes at least one of the following:

[0130] Step 131b: When the cleaning mode indicates that the first output component 151 outputs clean water, and the cleaning medium output by the second output component 152 includes one of gas, cleaning liquid and foam, the inlet of the second reversing valve 14 is controlled to be connected to the second outlet, and the clean water delivery component 11 is controlled to be in an open state, and at least one of the cleaning liquid delivery component 12 and the gas delivery component 13 is controlled to be in an open state.

[0131] Step 132b: When the cleaning mode indicates that the second output component 152 outputs gas and the first output component 151 outputs one of clean water, cleaning liquid and mixed liquid, the inlet of the second reversing valve 14 is controlled to be connected to the first outlet, and the gas delivery component 13 is controlled to be in an open state, and at least one of the clean water delivery component 11 and the cleaning liquid delivery component 12 is controlled to be in an open state.

[0132] Step 133b: When the cleaning mode indicates that the first output component 151 and the second output component 152 output one or a combination of clean water and gas respectively, the inlet of the control reversing valve 14 is connected to the first outlet and the second outlet, and the cleaning liquid delivery component 12 is controlled to be in a closed state, and at least one of the clean water delivery component 11 and the gas delivery component 13 is controlled to be in an open state.

[0133] As an example, the second reversing valve 14 may be a two-position three-way valve or a three-position three-way valve, which is not limited in the present disclosure.

[0134] See also Figure 7 ,by Figure 7 Taking the second reversing valve 14 as a two-position three-way valve as an example, the output of various cleaning media by the cleaning device 1 in accordance with the corresponding cleaning modes is described.

[0135] In the daily cleaning mode of the cleaning device 1, the control device controls the inlet of the second reversing valve 14 to be connected to the first outlet and disconnected from the second outlet. At this time, the cleaning device 1 can use the cleaning brush 17 to clean the dirt. If the water pump 111 in the cleaning device 1 is started and the cleaning liquid pump 121 is turned off, the first output component 151 can output clean water to the cleaning brush 17, and the cleaning device 1 is in the clean water mode. If the water pump 111 is turned off and the cleaning liquid pump 121 is started, the first output component 151 can output cleaning liquid to the cleaning brush 17, and the cleaning device 1 is in the cleaning liquid mode. If both the water pump 111 and the cleaning liquid pump 121 are started, the first output component 151 can output a mixed liquid to the cleaning brush 17, and the cleaning device 1 is in the mixed liquid mode.

[0136] In the fixed-point cleaning mode of the cleaning device 1, the control device controls the inlet of the second reversing valve 14 to be connected to the second outlet and disconnected from the first outlet. At this time, the second output component 152 can directly spray the dirty fixed point on the surface to be cleaned. If the cleaning liquid pump 121 in the cleaning device 1 is started and the air pump 131 is turned off, the second output component 152 can output cleaning liquid to the surface to be cleaned, and the cleaning device 1 is in the cleaning liquid mode. If the cleaning liquid is turned off and the air pump 131 is started, the second output component 152 can output gas to the surface to be cleaned, and the cleaning device 1 is in the gas mode. If both the air pump 131 and the cleaning liquid pump 121 are started, the second output component 152 can output foam to the surface to be cleaned, and the cleaning device 1 is in the foam mode.

[0137] In addition, in the daily cleaning mode of the cleaning device 1, although the inlet of the second reversing valve 14 is disconnected from the second outlet, the cleaning liquid cannot enter the second output component 152, but the gas delivery component 13 can still be connected to the second output component 152, then the air pump 131 can also be started, so that the second output component 152 outputs gas. At this time, the gas mode of the cleaning device 1 can be used in combination with any one of the clean water mode / cleaning liquid mode / mixed liquid mode. In this way, the first output component 151 and the second output component 152 can be used at the same time, and different cleaning media are output respectively, so that the cleaning device 1 can use different cleaning modes in combination. Of course, in other embodiments, the air pump 131 may not be started, and the present disclosure is not limited.

[0138] In addition, in the fixed-point cleaning mode of the cleaning device 1, although the inlet of the second reversing valve 14 is disconnected from the first outlet, the cleaning liquid cannot enter the first output component 151, but the clean water delivery component 11 can still be connected to the first output component 151, and the water pump 111 can also be started, so that the first output component 151 outputs clean water to the cleaning brush 17. At this time, the clean water mode of the cleaning device 1 can be used in combination with any one of the gas mode / cleaning liquid mode / foam mode. In this way, the first output component 151 and the second output component 152 can be used at the same time, and output different cleaning media respectively, so that the cleaning device 1 can use different cleaning modes in combination. Of course, in other embodiments, the water pump 111 may not be started, and the present disclosure is not limited thereto.

[0139] In other embodiments, Figure 7 The second reversing valve 14 shown can also be a three-position three-way valve. Figure 7 In the middle position of the second reversing valve 14, the inlet of the second reversing valve 14 can be connected to both the first outlet and the second outlet. At this time, if the cleaning liquid pump 121 is turned off, the clean water pump 111 and the air pump 131 are turned on, the first output component 151 and the second output component 152 of the cleaning device 1 can also output at least one of clean water and gas.

[0140] certainly, Figure 7 The second reversing valve 14 of the cleaning device 1 shown may also be a four-way valve or a five-way valve, etc., and the second reversing valve 14 is provided with several working positions, which the manufacturer may set according to user requirements, and the present disclosure does not impose any limitation thereto.

[0141] Of course, in other embodiments, when the cleaning device 1 has at least two groups of output components 15, each output component 15 can also be set toward the cleaning brush 17, or each output component 15 can also be set toward the ground or carpet waiting for the cleaning object, which is not limited by the present disclosure. In addition, other control valves such as stop valves, speed regulating valves or pressure regulating valves can also be set on the input pipelines of each conveying component of the cleaning device 1, and the control valve and the reversing valve 14 can be used in combination, which is not limited by the present disclosure.

[0146] It should be noted that when one element is considered to be "fixedly connected" to another element, the two can be fixed in a detachable connection or in a non-detachable connection, as long as the two can achieve force transmission. For example, shaft connection, sleeve connection, snap connection, plug connection, one-piece fixation, welding, etc. can be achieved in traditional technologies and can be flexibly selected according to actual application needs.
