Detailed Implementation

[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

If the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are for descriptive convenience only and should not be construed as indicating or implying relative importance.

[0034] With the development of technology and social progress, more and more families are starting 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 cleaning.

[0035] Understandably, various types of dirt, such as dust, hair, sweat, oil, limescale, or mold, can accumulate on different surfaces that need cleaning, including floors, kitchen countertops, and carpets. However, cleaning equipment in these technologies often only offers a water-washing mode, resulting in limited cleaning functionality and failing to meet users' needs in different cleaning scenarios, leading to a poor user experience.

[0036] Based on this, this application provides a cleaning device capable of offering multiple cleaning modes to suit various cleaning scenarios, thereby improving the cleaning effect and user experience. It is understood that the cleaning device provided in this application includes various cleaning devices such as floor scrubbers, vacuum cleaners, fabric cleaning machines, carpet cleaners, and robotic vacuum cleaners, and this application does not impose any limitations.

[0037] The cleaning equipment provided in this application will now be described in conjunction with the accompanying drawings.

[0038] See Figure 1 and Figure 2 This application provides a cleaning device 1, including a clean water pipeline 10. The clean water pipeline 10 is provided with a clean water tank 11, a clean water pump 12 connected to the clean water tank 11, and a water outlet 13 connected to the clean water pump 12. The clean water pipeline 10 is also provided with a first connector 14 located between the clean water pump 12 and the water outlet 13, the first connector 14 being used to connect a heating pipeline 20. The clean water pipeline 10 is also provided with a second connector 15 located between the clean water tank 11 and the first connector 14, the second connector 15 being used to connect a solution pipeline 30.

[0039] Specifically, the cleaning device 1 can provide a water washing cleaning mode through the clean water pipeline 10. The clean water tank 11 is used to store clean water and can be detachably installed on the body of the cleaning device 1 for convenient addition of clean water or cleaning and maintenance by the user. When in operation, the clean water pump 12 can transport the clean water in the clean water tank 11 to the outlet 13 for discharge, enabling the cleaning device 1 to output clean water. Understandably, the clean water can be used to clean easily removable light dirt such as dust or sweat stains.

[0040] To enrich the cleaning modes of the cleaning equipment 1, the clean water pipeline 10 is also equipped with a first connector 14, which can be used to connect to the heating pipeline 20. The first connector 14 is located between the clean water pump 12 and the outlet 13. When the heating pipeline 20 is in operation, the clean water pumped by the clean water pump 12 to the outlet 13 can be heated by the heating pipeline 20 before being discharged. Depending on the different heating temperatures provided by the heating pipeline 20, the clean water can be heated to form hot water or steam, allowing the outlet 13 to output hot water or steam, thereby improving the cleaning effect on dirt. Understandably, steam has a higher temperature and pressure than hot water, meaning that steam has a greater cleaning power than hot water. For example, hot water can be used to clean food residue or oil stains on the surface to be cleaned, utilizing the dissolving power of hot water to accelerate the dissolution of dirt. Steam can be used to clean stubborn stains such as limescale or mold on the surface to be cleaned, utilizing the high temperature and pressure of steam to soften stubborn dirt, thereby improving the sterilization and disinfection effect of the cleaning equipment 1. When the heating pipe 20 is in the off state, the clean water pump 12 delivers clean water to the outlet 13 without heating, meaning the clean water output from the outlet 13 can be used as cold water. Understandably, cold water can be used to clean protein-based stains, starch-based stains, or blood stains, preventing these stains from solidifying or thickening upon heating, thus avoiding increased cleaning difficulty. With this configuration, by connecting the heating pipe 20 to the clean water pipe 10 and controlling the heating pipe 20 to be in the working or off state, the cleaning equipment 1 can have both cold water and hot water washing modes, and it can also have a steam cleaning mode.

[0041] Meanwhile, to further enrich the cleaning modes of the cleaning equipment 1, the clean water pipeline 10 is also provided with a second connector 15, which can be used to connect the solution pipeline 30. The second connector 15 is located between the clean water tank 11 and the first connector 14. When the solution pipeline 30 is in operation, it can supply cleaning fluid to the outlet 13. The cleaning fluid can be used to clean stubborn stains such as oil or mold. Understandably, the cleaning fluid includes various liquids with cleaning functions, such as oil stain cleaner, floor cleaner, fabric cleaner, carpet cleaner, glass cleaner, disinfectant cleaner, or mold remover, and this application does not impose any limitations. With this configuration, at least one of the clean water pipeline 10 and the solution pipeline 30 can supply liquid to the outlet 13, enabling the outlet 13 to output clean water, cleaning fluid, and a mixture of clean water and cleaning fluid. Therefore, the cleaning equipment 1 can also have a solution cleaning mode that outputs cleaning fluid or a mixture of these two fluids.

[0042] In addition, when the clean water pipeline 10 is in operation, at least one of the solution pipeline 30 and the heating pipeline 20 can be in operation, so that the outlet 13 can output one of cold water, hot water, cold cleaning liquid, hot cleaning liquid, cold mixed liquid, hot mixed liquid, water vapor, and mixed liquid vapor, which will not be described in detail in this application.

[0043] Thus, the cleaning device 1 provided in this application, by connecting a heating pipe 20 and a solution pipe 30 to the clean water pipe 10, enables the cleaning device 1 to have a water washing cleaning mode that can output cold or hot water, a steam cleaning mode that can output water vapor or mixed liquid vapor, and a solution cleaning mode that can output cleaning liquid or mixed liquid, thereby enriching the cleaning modes of the cleaning device 1. This allows users to select the corresponding cleaning mode in different cleaning scenarios, thereby improving the cleaning effect of the cleaning device 1 and enriching the user experience.

[0044] In one embodiment, at least one of the first connector 14 and the second connector 15 may be configured as a pipe fitting or a control valve to facilitate the connection of the heating pipe 20 and the solution pipe 30, which is not limited in this application.

[0045] See Figure 3 In one embodiment, the cleaning device 1 further includes a solution pipeline 30, which includes a solution pump 31 connected to the second connector 15 and a solution tank 32 connected to the solution pump 31, so that at least one of the water pump 12 and the solution pump 31 can be in operation.

[0046] It should be noted that the solution tank 32 is used to store various cleaning solutions with cleaning functions, such as oil stain cleaning solution, floor cleaning solution, fabric cleaning solution, carpet cleaning solution, glass cleaning solution, disinfectant cleaning solution, or mold removal cleaning solution. The solution pump 31 can deliver the cleaning solution in the solution tank 32 to the outlet 13, so that the outlet 13 can output the cleaning solution, thereby realizing the solution cleaning mode of the cleaning device 1. Understandably, the solution pump 31 and the clean water pump 12 can be peristaltic pumps and / or diaphragm pumps, etc., respectively, and this application does not impose any limitations.

[0047] See Figure 3 In one embodiment, the second connector 15 may be located between the clean water tank 11 and the clean water pump 12. In this case, the clean water pump 12 can act between the solution pump 31 and the outlet 13 to control the connection and disconnection of the pipeline between the solution pump 31 and the outlet 13. That is, due to the structure of the clean water pump 12, the pipeline between the solution pump 31 and the outlet 13 is only connected when the clean water pump 12 is in the working state. When the clean water pump 12 is in the off state, the pipeline between the solution pump 31 and the outlet 13 is disconnected.

[0048] Understandably, when the clean water pump 12 is in operation, the clean water in the clean water tank 11 can flow out sequentially through the second connector 15, the clean water pump 12, the first connector 14, and the outlet 13. At this time, if the solution pump 31 is also in operation, the liquid in the solution tank 32 can flow out sequentially through the solution pump 31, the second connector 15, the clean water pump 12, the first connector 14, and the outlet 13, so that the outlet 13 can output a mixture of clean water and cleaning solution. If the solution pump 31 is in the off state, only clean water flows out of the outlet 13.

[0049] With this configuration, when the water pump 12 and the solution pump 31 are working simultaneously, the power of the two pumps can be superimposed, so that the water and cleaning solution in the pipeline can have enough power to flow to the outlet 13, ensuring that the outlet 13 can smoothly discharge the liquid.

[0050] In other embodiments, the second connector 15 may also be located between the water pump 12 and the first connector 14. With this configuration, when the solution pump 31 is in operation, the liquid in the solution tank 32 flows sequentially through the solution pump 31, the second connector 15, the first connector 14, and the outlet 13, allowing the outlet 13 to directly output the cleaning solution. Of course, when the solution pump 31 is in operation, the water pump 12 can also be in operation, allowing both the cleaning solution and clean water to flow to the outlet 13, so that the outlet 13 can output a mixture of clean water and cleaning solution. This application does not limit the specific installation position of the second connector 15 and can adjust it according to actual needs.

[0051] In one embodiment, to facilitate connection of the solution pipeline 30 to the clean water pipeline 10, the second connector 15 may include a pipe fitting with at least three interfaces, including a first interface communicating with the clean water tank 11, a second interface communicating with the clean water pump 12, and a third interface communicating with the solution pump 31. Understandably, the second connector 15 may be a tee connector.

[0052] See Figure 4 In one embodiment, the cleaning device 1 further includes a heating pipe 20, which includes a heater 21 communicating with the first connector 14 and a steam outlet 22 communicating with the heater 21, such that at least one of the steam outlet 22 and the water outlet 13 can be in a working state.

[0053] Specifically, heater 21 is used to heat the liquid in the pipeline. Heater 21 includes heating components such as boiler assemblies or electric heating rod assemblies that can generate steam, and this application is not limited thereto.

[0054] Steam outlet 22 can be used to output water vapor or mixed liquid steam generated in the pipeline, so that the steam outlet 22 of heating pipeline 20 and the water outlet 13 of clean water pipeline 10 can be used independently. That is, water outlet 13 is used to output liquids such as cold water, hot water, cold mixed liquid or hot mixed liquid, and is no longer used to output water vapor or mixed liquid steam.

[0055] Understandably, the temperature difference between steam and cold water is significant. When steam and cold water share the same outlet, the outlet that has just discharged cold water will lower the steam temperature, making it impossible to maintain the stability of the steam output from cleaning device 1. Similarly, the residual heat from the outlet that has just discharged steam will also heat the cold water, causing cleaning device 1 to output some warm or hot water, thus affecting the cleaning effect in cold water cleaning scenarios.

[0056] In this way, by using the steam outlet 22 and the water outlet 13 independently, the mutual interference between the cleaning equipment 1 in different cleaning modes can be avoided, thereby ensuring the cleaning effect of the cleaning equipment 1 in different modes.

[0057] In addition, when the heating pipe 20 is in operation and the steam outlet 22 outputs water vapor or mixed steam, in order to relieve the working pressure of the steam outlet 22, the cleaning equipment 1 can simultaneously connect the steam outlet 22 and the water outlet 13 through the first connector 14 to distribute the working pressure in the pipe to the water outlet 13 and release pressure at the water outlet 13, so as to avoid blockage of the pipe or steam outlet 22 of the cleaning equipment 1 and thus avoid the risk of explosion due to high temperature and high pressure.

[0058] See Figure 5To facilitate the connection of the cleaning device 1 to the heating pipe 20 and to match various cleaning modes, the first connector 14 includes a first control valve 141. The first control valve 141 has at least three working ports, including a first inlet connected to the clean water pump 12, a first outlet connected to the water outlet 13, and a second outlet connected to the heater 21. The first control valve 141 is configured such that: when the first inlet and the first outlet are connected, the clean water pump 12 is in the working state, the heater 21 is in the off state, and the solution pump 31 can switch between the working state and the off state; when the first inlet and the second outlet are connected, both the clean water pump 12 and the heater 21 are in the working state, and the solution pump 31 can switch between the working state and the off state.

[0059] Understandably, the first control valve 141 may be a three-way directional valve, enabling the clean water pump 12 to supply clean water to the outlet 13 and / or the steam outlet 22.

[0060] Taking the first control valve 141 as a two-position three-way valve as an example: when the first inlet and the first outlet are connected, the clean water pump 12 is in working state and the heater 21 is in closed state. If the solution pump 31 is also in closed state, the outlet 13 can output cold water; if the solution pump 31 is in working state, the outlet 13 can output a mixture of clean water and cleaning solution.

[0061] When the first inlet and the second outlet are connected, both the water pump 12 and the heater 21 are in operation. If the solution pump 31 is in the off state, the steam outlet 22 can output water vapor; if the solution pump 31 is in operation, the steam outlet 22 can output mixed liquid steam.

[0062] It should be noted that, in one embodiment, by controlling the first control valve 141, the water outlet 13 and the steam outlet 22 can be opened alternately. For example, within one minute, the first inlet and the first outlet are first connected, allowing the clean water pump 12 to operate continuously at a flow rate of 20 ml / min for 50 seconds, while the solution pump 31 can be opened or closed, allowing the water outlet 13 to continuously output cold water or a mixed solution; then, the first inlet and the second outlet are connected, allowing the clean water pump 12 to operate continuously at a flow rate of 100 ml / min for 10 seconds, while the solution pump 31 can be opened or closed, allowing the steam outlet 22 to continuously output water vapor or a mixed solution vapor. This configuration, through the cyclical alternation of the water outlet 13 and the steam outlet 22, allows the clean water pump 12 to operate at alternating high and low power, preventing the clean water pump 12 from overheating rapidly, thus balancing power and extending the service life of the cleaning equipment 1.

[0063] Furthermore, this application allows the heating pipe 20 to be connected to the clean water pipe 10 via the first control valve 141, and enables the steam outlet 22 and the water outlet 13 to operate independently. Compared to cleaning devices 1 with steam cleaning modes in related technologies, the cleaning device 1 provided by this application has a simpler pipe connection, which can reduce the failure rate of the cleaning device 1 and facilitate after-sales maintenance and replacement. At the same time, the cleaning device 1 of this application can achieve a variety of cleaning modes through simple pipe connections, which can improve the user experience and make it suitable for various cleaning scenarios (such as disinfecting the floor, removing stubborn stains, and daily garbage removal), enabling the cleaning device 1 provided by this application to achieve the purpose of multi-purpose use.

[0064] See Figure 5 In one embodiment, the cleaning device 1 further includes a filter 40, which connects the heater 21 and the steam outlet 22. Understandably, the orifice of the steam outlet 22 is typically designed to be small in order to generate a strong steam flow. However, impurities such as scale or particulate matter carried in the liquid can easily clog the steam outlet 22. Once the steam outlet 22 is clogged, the steam volume will decrease, the spray force will be insufficient, the steam cleaning mode of the cleaning device 1 will fail, and maintenance costs will be high. This application installs a filter device before the steam outlet 22, so that the filter 40 can filter out impurities carried by the liquid flowing to the steam outlet 22, thus preventing clogging of the steam outlet 22.

[0065] See Figure 5 In one embodiment, the cleaning device 1 further includes a booster 50 connected between the heater 21 and the steam outlet 22. Understandably, the greater the pressure of the steam, the greater its penetrating power. The booster 50 can be used to pressurize the liquid / steam within the pipe, enabling the water vapor / mixed liquid vapor ejected from the steam outlet 22 to be ejected at greater pressure and higher speed, utilizing the powerful impact force to perform deep cleaning of the surface to be cleaned.

[0066] With this configuration, when the cleaning device 1 cleans the gaps in the floor, the deep fibers of the carpet, or the porous surface to be cleaned, the pressure can be increased by the booster 50 to increase the pressure of the steam ejected from the steam outlet 22, so that the cleaning device 1 can have sufficient impact force to clean the dirt deep in the surface to be cleaned, thereby improving the cleaning power of the cleaning device 1.

[0067] See Figure 5In one embodiment, the cleaning device 1 further includes a liquid detector 60, which is connected between the water pump 12 and the first inlet. It should be noted that the liquid detector 60 can be used to detect whether liquid is flowing in the pipeline. When the water pump 12 and / or the solution pump 31 are in operation, if the liquid detector 60 detects no liquid flow in the pipeline, it will emit an audible and / or visual alarm, and cause the control system of the cleaning device 1 to shut down the water pump 12 and / or the solution pump 31 to prevent dry burning and damage to the water pump 12 / solution pump 31.

[0068] Understandably, the alarm issued by the liquid detector 60 can prompt the user to check whether there is a shortage of water in the clean water tank 11 and / or the solution tank 32. If there is sufficient liquid in both the clean water tank 11 and the solution tank 32, it indicates that there is a blockage in the pipeline of the cleaning equipment 1, and the pipeline of the cleaning equipment 1 needs to be repaired and inspected to ensure the safe use of the cleaning equipment 1.

[0069] Compared to related technologies that only install a level detector in the clean water tank 11, which only triggers an alarm when the water level in the tank is extremely low, there is usually a time delay between the time the clean water tank 11 is empty and the time the clean water pump 12 empties the remaining water in the pipes. During this delay, the cleaning device 1 may already be in a "semi-dry" state. Therefore, this application, by directly installing a liquid detector 60 in the pipes, can issue alarms more directly, sensitively, and accurately. That is, as long as the water flow in the pipes of the cleaning device 1 is interrupted while the clean water pump 12 / solution pump 31 is operating, the liquid detector 60 will directly alarm to remind the user, regardless of whether there is still liquid in the clean water tank 11 / solution tank 32, so as to further check the cleaning device 1 and avoid safety hazards caused by pipe blockage or other problems.

[0070] See Figure 6 In one embodiment, the first connector 14 includes a second control valve 142, which has at least three working ports, including a second inlet, a third outlet communicating with the water outlet 13, and a fourth outlet communicating with the steam outlet 22. The heater 21 is connected between the water pump 12 and the second inlet. The second control valve 142 is configured such that when the second inlet and the third outlet are connected, the water pump 12 is in a working state, and the heater 21 and the solution pump 31 can switch between a working state and a closed state; when the second inlet and the fourth outlet are connected, both the water pump 12 and the heater 21 are in a working state, and the solution pump 31 can switch between a working state and a closed state.

[0071] It should be noted that, Figure 6 The piping structure of the cleaning device 1 shown differs from that of the cleaning device 1 in the previous embodiment in that: Figure 6The heater 21 is positioned between the clean water pump 12 and the first connector 14.

[0072] With this configuration, when the second inlet and third outlet are connected, and both the clean water pump 12 and heater 21 are operating, if the solution pump 31 is off, outlet 13 can output hot water; if the solution pump 31 is operating, outlet 13 can output a hot mixture. At this time, if heater 21 is off, outlet 13 can still output cold water or a cold mixture. In other words, Figure 6 Compared to the cleaning device 1 in the aforementioned embodiment, the cleaning device 1 shown has the following features: with a water outlet 13 and a steam outlet 22, the water outlet 13 also has a cleaning mode that can output hot water or a hot mixture.

[0073] Understandably, the second control valve 142 can also be configured as a two-position three-way valve, and this application does not impose any restrictions.

[0074] In one embodiment, the cleaning device 1 typically has a roller brush for cleaning the surface to be cleaned. When the cleaning device 1 has a water outlet 13 and a steam outlet 22, the water outlet 13 of the cleaning device 1 may be oriented toward the roller brush, and the steam outlet 22 may be oriented toward the surface to be cleaned.

[0075] This configuration allows the cold water, hot water, cold mixture, or hot mixture output from outlet 13 to wet the roller brush, enabling the cleaning device 1 to wipe the surface to be cleaned. For example, a roller brush wetted with cold water or a cold mixture can be used to wipe off protein-based, starch-based, or blood-based stains, preventing these stains from solidifying upon heating and becoming difficult to clean. Of course, a roller brush wetted with cold water or a cold mixture can also be used to wipe off light dirt such as dust, hair, or sweat stains. A roller brush wetted with hot water or a hot mixture can be used to wipe off stubborn dirt such as oil stains, scale, or mold, dissolving this dirt through heat to reduce cleaning difficulty. Simultaneously, steam outlet 22 can be used to directly spray water vapor or a mixture of steam onto the surface to be cleaned, further softening stubborn dirt and improving the cleaning effect of the cleaning device 1 on stubborn dirt.

[0076] See Figure 7 In one embodiment, the clean water pipeline 10 further includes a third connector 16 located between the heater 21 and the steam outlet 22, the third connector 16 being used to connect the nozzle 70 so that one of the steam outlet 22 and the nozzle 70 can be in a working state.

[0077] It should be noted that, in Figure 7In the cleaning device 1 shown, the water outlet 13 can be used to output cold water or a mixed liquid, but it cannot output hot water or a hot mixed liquid. At this time, the cleaning device 1 can also be connected to the nozzle 70 via the third connector 16. The nozzle 70 can be used to directly spray dirt onto the surface to be cleaned. Furthermore, the liquid flowing from the cleaning device 1 to the nozzle 70 can also pass through the heater 21, allowing the nozzle 70 to spray both cold water or a cold mixed liquid, and also hot water or a hot mixed liquid. Understandably, the nozzle 70 and the steam outlet 22 are used selectively to avoid the large temperature difference between cold water and steam affecting the cleaning effect if they share a single outlet.

[0078] As an example, the third connector 16 can be configured as a three-way directional valve, with its inlet connected to the heater 21, one outlet connected to the steam outlet 22, and the other outlet connected to the nozzle 70. The third connector 16 can be configured such that when the inlet of the three-way directional valve is connected to the nozzle 70, the clean water pump 12 is in operation; if the heater 21 and the solution pump 31 are closed, the nozzle 70 can spray cold water; if the heater 21 is closed and the solution pump 31 is in operation, the nozzle 70 can spray a cold mixture; if the heater 21 is in operation and the solution pump 31 is closed, the nozzle 70 can spray hot water; and if both the heater 21 and the solution pump 31 are in operation, the nozzle 70 can spray a hot mixture.

[0079] With this setup, when there is a thick, sauce-like residue on the surface to be cleaned, the user can use the nozzle 70 of the cleaning device 1 to spray some liquid onto the residue to dilute or pre-dissolve it, so that the roller brush can be used to clean the residue later. If there are still traces of residue on the surface to be cleaned, water vapor or mixed liquid vapor can be sprayed out from the steam outlet to remove them, thereby improving the cleaning effect of the cleaning device 1.

[0080] Understandably, nozzle 70 can be used to spray liquid onto dirt at fixed points and / or in fixed quantities. The spray range and spray force of nozzle 70 can be adjusted according to user needs, and this application does not make such settings.

[0081] In one embodiment, when the cleaning device 1 is equipped with a roller brush for cleaning the surface to be cleaned, a water outlet 13, a steam outlet 22, and a nozzle 70, the water outlet 13 can be positioned towards the roller brush, and the nozzle 70 and steam outlet 22 can be positioned towards the surface to be cleaned, with the distance between the steam outlet 22 and the surface to be cleaned being less than the distance between the nozzle 70 and the surface to be cleaned. For example, the nozzle 70 and steam outlet 22 can be located on the upper and lower sides of the roller brush, respectively, with the nozzle 70 located above the roller brush and the steam outlet 22 located below the roller brush.

[0082] This configuration, with the steam outlet 22 positioned close to the surface to be cleaned, ensures that the steam or mixed liquid steam emitted from the outlet acts directly on the surface with sufficient temperature and pressure. This prevents the steam or mixed liquid steam from losing temperature and pressure due to a long transport path, thus avoiding a reduction in cleaning effectiveness. Simultaneously, the nozzle 70's position above the roller brush allows for a wider spray range, increasing coverage of dirt and improving the cleaning efficiency of the cleaning device 1. Furthermore, the placement of the nozzle 70 and steam outlet 22 does not interfere with the water outlet 13 supplying water to the roller brush, ensuring the normal operation of the roller brush.

[0083] Taking a floor scrubber as an example, cleaning equipment 1 includes a floor brush assembly and a handheld device connected to the floor brush assembly. The floor brush assembly includes a floor brush housing and a roller brush rotatably connected to the floor brush housing. The handheld device is movably connected to the floor brush housing to allow the user to adjust the handheld angle of the cleaning equipment. A clean water tank 11 can be installed on the handheld device to allow the user to remove the clean water tank 11 for replenishment or cleaning and maintenance. A solution tank 32 can be installed in the handheld device or the floor brush housing; this application does not impose any limitations. A clean water pump 12 and a solution pump 31 can be installed in the floor brush housing. A water outlet 13 can be connected to the floor brush housing and oriented towards the roller brush. A steam outlet 22 and a nozzle 70 are respectively connected to the floor brush housing and located on the upper and lower sides of the roller brush.

[0084] See Figure 8 In one embodiment, when the cleaning device 1 includes a water outlet 13, a steam outlet 22, and a nozzle 70, the first connector 14 includes a third control valve 143. The third control valve 143 includes at least four working ports, including a third inlet, a fifth outlet communicating with the water outlet 13, a sixth outlet communicating with the steam outlet 22, and a seventh outlet communicating with the nozzle 70. The heater 21 is connected between the clean water pump 12 and the third inlet. The third control valve 143 is configured such that: when the third inlet is connected to the fifth outlet or the seventh outlet, the clean water pump 12 is in an operating state, and the heater 21 and the solution pump 31 can switch between an operating state and a closed state; when the third inlet is connected to the sixth outlet, both the clean water pump 12 and the heater 21 are in an operating state, and the solution pump 31 can switch between an operating state and a closed state.

[0085] Understandably, the third control valve 143 can be configured as a three-position four-way directional valve. When the third inlet and the fifth outlet of the third control valve 143 are connected, when the clean water pump 12 is in operation, if the heater 21 and the solution pump 31 are in the off state, the outlet 13 can output cold water to the roller brush; if the heater 21 is in the off state and the solution pump 31 is in operation, the outlet 13 can output cold mixed liquid to the roller brush; if the heater 21 is in operation and the solution pump 31 is in the off state, the outlet 13 can output hot water to the roller brush; if both the heater 21 and the solution pump 31 are in operation, the outlet 13 can output hot mixed liquid to the roller brush.

[0086] When the third inlet and sixth outlet of the third control valve 143 are connected, when the clean water pump 12 and the heater 21 are in operation, if the solution pump 31 is in the closed state, the steam outlet 22 can spray water vapor onto the dirt; if the solution pump 31 is in operation, the steam outlet 22 can spray mixed liquid steam onto the dirt.

[0087] With the third inlet and seventh outlet of the third control valve 143 connected, when the clean water pump 12 is in operation, if the heater 21 and the solution pump 31 are in the off state, the nozzle 70 can output cold water to the dirty area; if the heater 21 is in the off state and the solution pump 31 is in operation, the nozzle 70 can output cold mixed liquid to the dirty area; if the heater 21 is in operation and the solution pump 31 is in the off state, the nozzle 70 can output hot water to the dirty area; if both the heater 21 and the solution pump 31 are in operation, the nozzle 70 can output hot mixed liquid to the dirty area.

[0088] This setting Figure 8 The cleaning device 1 can connect the water outlet 13, steam outlet 22, and nozzle 70 to the same control valve, thereby reducing the number of control valves in the cleaning device 1, simplifying the piping structure, and lowering the failure rate of the cleaning device 1. Meanwhile, Figure 8 The cleaning device 1 can also control the water outlet 13, steam outlet 22 and nozzle 70 respectively through the third control valve 143, so that the cleaning device 1 has multiple cleaning modes to meet the user's cleaning needs for multiple cleaning scenarios and improve the user experience.
