[0036] Today, with the development of technology and society, cleaning equipment such as vacuum cleaners, floor scrubbers, and robotic vacuum cleaners have entered many households, effectively improving the efficiency and effectiveness of home cleaning. Facing various stains such as dust, hair, oil, and mold on floors, kitchen countertops, or carpets, these complex cleaning scenarios place diverse demands on cleaning equipment. However, most cleaning equipment on the market is still limited to a single water-washing mode, making it difficult to comprehensively address these complex situations and thus failing to meet user needs, resulting in a poor user experience.

[0037] Based on this, this application provides a cleaning device capable of offering multiple cleaning modes to adapt to complex cleaning scenarios, achieving multi-functionality and thus meeting user needs and improving 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.

[0038] The cleaning equipment provided in this application will now be described in conjunction with the accompanying drawings.

[0039] See Figure 1 This application provides a cleaning device 1, including a roller brush 40 for cleaning a surface 2 to be cleaned, a clean water pipe 10, a heating pipe 20, and a foam pipe 30. The clean water pipe 10 has a clean water source 11 and a water outlet 12 connected to the clean water source 11. The water outlet 12 is positioned towards the roller brush 40 to output room temperature water to the roller brush 40. The heating pipe 20 has a heating source 21 connected to the clean water pipe 10 and a steam outlet 22 connected to the heating source 21. The steam outlet 22 is positioned towards the surface 2 to be cleaned to output water vapor to the surface 2 to be cleaned. The foam pipe 30 has a nozzle 31 connected to the heating pipe 20 and a foam source 32 connected between the heating pipe 20 and the nozzle 31. The nozzle 31 is positioned towards the surface 2 to be cleaned to output at least one of foam, room temperature water, and hot water to the surface 2 to be cleaned.

[0040] Specifically, the roller brush 40 is rotatably mounted on the body of the cleaning device 1, and the surface 2 to be cleaned includes the floor, kitchen countertop, or carpet fabric, etc. The cleaning device 1 can wipe and clean the dirt on the surface 2 by rotating the roller brush 40.

[0041] The cleaning device 1 can supply room temperature water to the roller brush 40 through the clean water pipe 10. Understandably, when the clean water pipe 10 is in operation, the clean water source 11 can supply clean water to the clean water pipe 10, so that the clean water can flow from the water outlet 12 to the surface of the roller brush 40, so as to wet the roller brush 40 with room temperature water, making it easier for the roller brush 40 to wipe away light stains such as dust or sweat stains on the surface to be cleaned 2.

[0042] The cleaning device 1 can heat room temperature water via heating pipe 20. Understandably, depending on the heating temperature provided by the heating source 21, room temperature water can be heated to form steam or hot water. Steam is output from steam outlet 22 to the surface to be cleaned 2, while hot water is output from nozzle 31 to the surface to be cleaned 2. For example, when the cleaning device 1 outputs steam to the surface to be cleaned 2 through steam outlet 22, the clean water source 11 can supply room temperature water to the heating pipe 20. The heating pipe 20 can heat the room temperature water to form steam, which is then transported to the surface to be cleaned 2 through steam outlet 22 to clean stubborn stains such as scale or mold on the surface to be cleaned 2. Understandably, the temperature and pressure of steam can soften stubborn dirt, improving the sterilization and disinfection effect of the cleaning device 1. For example, when the cleaning device 1 sprays hot water onto the surface 2 to be cleaned through the nozzle 31, the clean water source 11 can supply room temperature water to the heating pipe 20. The heating pipe 20 can heat the room temperature water to form hot water, which is then delivered to the surface 2 to be cleaned through the nozzle 31 to accelerate the dissolution of dirt using the dissolving power of the hot water. The hot water can be used to clean food residue or grease and other dirt on the surface 2 to be cleaned.

[0043] With the heating source 21 off, the cleaning device 1 can also spray room temperature water onto the surface 2 to be cleaned through the nozzle 31. Understandably, when there are stains such as protein, starch, or blood on the surface 2, these stains will solidify or thicken after being dissolved by hot water, increasing the difficulty of cleaning. Using room temperature water to dissolve these stains not only prevents them from solidifying or thickening when heated, but also dilutes them, thus reducing the difficulty of cleaning. Therefore, when the cleaning device 1 sprays room temperature water onto the surface 2 through the nozzle 31, the clean water source 11 can provide unheated room temperature water to the nozzle 31, allowing the room temperature water to be output from the nozzle 31 and directly sprayed onto the stains on the surface 2.

[0044] The cleaning device 1 can also spray foam onto the surface 2 to be cleaned via nozzle 31. Understandably, the foam source 32 can generate foam during operation, allowing the foam to be sprayed onto the surface 2 through nozzle 31. The foam dissolves dirt on the surface 2, thereby improving the cleaning effect. The foam has low fluidity, allowing it to remain on the dirty surface for a longer period, increasing the persistence of dirt decomposition and further enhancing the cleaning effect. With this configuration, the nozzle 31 of the cleaning device 1 can output foam, hot water, or room temperature water to the surface 2 to be cleaned.

[0045] Thus, the cleaning device 1 provided by this application can output room temperature water to the roller brush 40 and output water vapor, spray foam, spray hot water or spray room temperature water to the surface to be cleaned 2. Therefore, the cleaning device 1 provided by this application can have multiple functions and achieve multi-purpose use, so that users can select the corresponding cleaning mode in various complex cleaning scenarios to improve the user experience.

[0046] See Figure 1 In one embodiment, the cleaning device 1 provided in this application has at least the following cleaning modes: water washing mode, water steam mode, spot spray foam mode, spot spray hot water mode, and spot spray room temperature water mode.

[0047] Specifically, in water washing mode, the clean water source 11 is in operation, causing the outlet 12 to output room temperature water to wet the roller brush 40. In steam mode, the clean water source 11 and the heating source 21 are in operation, causing the steam outlet 22 to output steam to sterilize and disinfect the surface 2 to be cleaned. In spot spray foam mode, the foam source 32 is in operation, causing the nozzle 31 to output foam to dissolve dirt on the surface 2 to be cleaned over a long period of time. In spot spray hot water mode, the clean water source 11 and the heating source 21 are in operation, causing the nozzle 31 to output hot water to accelerate the dissolution of oil stains and other dirt using the dissolving power of hot water. In spot spray room temperature water mode, the clean water source 11 is in operation, causing the nozzle 31 to output room temperature water to dissolve dirt such as protein, starch, or blood stains on the surface 2 to be cleaned, preventing these dirt from solidifying when heated.

[0048] Understandably, the cleaning modes of the cleaning device 1, such as water washing mode, steam mode, foam spray mode, hot water spray mode, and room temperature water spray mode, can be used individually or in combination, and this application does not impose any restrictions. For example, when there is residual dirt on the surface 2 to be cleaned, the user can use the nozzle 31 of the cleaning device 1 to spray foam onto the dirt to pre-dissolve the dirt, so that the roller brush 40 can be used to clean the dirt later. If there are still traces of dirt on the surface 2 to be cleaned, water vapor can be sprayed from the steam outlet 22 for further sterilization and disinfection, thereby improving the cleaning effect of the cleaning device 1. In other words, the foam spray mode of the cleaning device 1 can be used in combination with the steam mode, and the foam spray mode can also be used in combination with the water washing mode, etc., thereby improving the cleaning effect of the cleaning device 1. Understandably, the user can combine various cleaning modes according to the usage needs, and this application will not elaborate on this.

[0049] See Figure 2 In one embodiment, to match the cleaning device 1 to achieve various cleaning modes, the cleaning device 1 further includes a first control valve 50 and a second control valve 60. The first control valve 50 has a first inlet connected to a clean water source 11, a water outlet connected to a water outlet 12, and a heating interface connected to a heating source 21. The second control valve 60 has a second inlet connected to the heating source 21, a steam interface connected to a steam outlet 22, and a nozzle interface connected to a nozzle 31. A foam source 32 is connected between the nozzle interface and the nozzle 31. The first control valve 50 and the second control valve 60 are configured as follows: In water washing mode, the first inlet is connected to the water outlet interface, and the second inlet is connected to the steam interface or nozzle interface. In steam mode, the first inlet is connected to the heating interface, and the second inlet is connected to the steam interface; In the point spray foam mode, the first inlet is connected to the water outlet or heating interface, and the second inlet is connected to the steam interface. In the hot water spray mode or the room temperature water spray mode, the first inlet is connected to the heating interface, and the second inlet is connected to the nozzle interface.

[0050] Understandably, the first control valve 50 and the second control valve 60 can each be a three-way directional valve. The first control valve 50 can be used to divert room temperature water supplied by the clean water pipeline 10 to the outlet 12 or the heating pipeline 20. The second control valve 60 can be used to divert liquid in the heating pipeline 20 to the steam outlet 22 or the nozzle 31.

[0051] As an example, in water washing mode, the first inlet is connected to the water outlet, allowing room temperature water supplied by the clean water pipe 10 to flow to the water outlet 12, and then from the water outlet 12 to the roller brush 40, thereby wetting the roller brush 40. At this time, the room temperature water supplied by the clean water pipe 10 will not flow to the heating pipe 20, so the second inlet can be connected to the steam interface or the nozzle interface. The steam outlet 22 will not output water vapor, and the nozzle 31 will not spray hot water or room temperature water. The water washing mode of the cleaning device 1 can be used independently. In addition, when the foam source 32 is in working condition, the nozzle 31 can directly spray foam, allowing the water washing mode and the foam spraying mode to be used in combination.

[0052] In steam mode, the first inlet is connected to the heating interface, allowing room-temperature water supplied by the clean water pipe 10 to enter the heating pipe 20 and be heated to form steam. The second inlet is connected to the steam interface, allowing steam to be output from the steam outlet 22 to the surface to be cleaned 2, thus sterilizing and disinfecting the dirt on the surface 2. At this time, the steam mode of the cleaning device 1 can be used independently. When the foam source 32 is in operation, the nozzle 31 can also directly spray foam, allowing the steam mode and the foam spraying mode to be used in combination.

[0053] In the spot-spray foam mode, the second inlet is connected to the steam interface to prevent foam from flowing back from the nozzle interface into the heating pipe 20. At this time, the spot-spray foam mode of the cleaning device 1 can be used independently. Furthermore, when the clean water source 11 is in operation, the first inlet can also be connected to the water outlet interface, allowing the water outlet 12 to output room temperature water to the roller brush 40. When both the clean water source 11 and the heating source 21 are in operation, the first inlet can also be connected to the heating interface, allowing the steam outlet 22 to output water vapor to the surface 2 to be cleaned; this will not be elaborated upon in this application.

[0054] In either the hot water or room temperature water spray mode, the first inlet is connected to the heating interface, allowing room temperature water supplied by the clean water pipe 10 to enter the heating pipe 20. With the heating source 21 in operation, the room temperature water is heated to form hot water, and the second inlet is connected to the nozzle interface, allowing the nozzle 31 to spray hot water onto the surface to be cleaned at point 2. In this mode, the hot water spray mode of the cleaning device 1 can be used independently. When the heating source 21 is off, room temperature water can be output directly from the nozzle 31 without heating, allowing the nozzle 31 to spray room temperature water onto the surface to be cleaned at point 2. In this mode, the room temperature water spray mode of the cleaning device 1 can also be used independently.

[0055] Understandably, for the cleaning device 1 provided in this application, steam, hot water, and room temperature water need to be output separately through steam outlet 22 and nozzle 31. That is, steam outlet 22 is used to output steam, and nozzle 31 is used to spray room temperature water, hot water, or foam, but nozzle 31 is not used to output steam. This is because the temperature difference between steam and room temperature water is large. When steam and room temperature water share the same outlet, the outlet that has just discharged room temperature water will lower the temperature of the steam, making it impossible to maintain the stability of the steam output of cleaning device 1. Similarly, the residual heat of steam outlet 22 will also heat the room temperature water, causing cleaning device 1 to output some warm or hot water, thus reducing the cleaning effect of room temperature water on protein-based or blood-stained dirt. In this way, by separately setting steam outlet 22 and nozzle 31, the cleaning device 1 provided in this application can avoid mutual interference between cleaning device 1 in different cleaning modes, thereby ensuring the cleaning effect of cleaning device 1 in different modes.

[0056] Therefore, this application allows the heating pipe 20 to be connected to the clean water pipe 10 via the first control valve 50, and the foam pipe 30 to be connected to the heating pipe 20 via the second control valve 60. Furthermore, the water outlet 12, steam outlet 22, and nozzle 31 can be used independently or in combination, flexibly coordinating with various cleaning modes of the cleaning equipment 1. In addition, the cleaning equipment 1 provided by this application can achieve pipe connections for multiple cleaning modes using only two control valves, reducing the failure rate of the cleaning equipment 1 and facilitating after-sales maintenance and replacement.

[0057] See Figure 3 In one embodiment, to enable the cleaning device 1 to spray foam in spots, the foam pipeline 30 is further provided with a connector 33 connecting the nozzle interface and the nozzle 31. The foam source 32 includes a solution pump 321, an air pump 323, a foamer 324, and a solution tank 322. The solution pump 321, air pump 323, and foamer 324 are respectively connected to the connector 33. The solution tank 322 is connected to the solution pump 321, and the nozzle 31 is connected to the foamer 324. In the spot-spray foam mode, the solution pump 321 and air pump 323 are in operation.

[0058] It should be noted that the connector 33 can be configured as a pipe fitting or a control valve to facilitate the connection of the foam source 32 between the nozzle interface and the nozzle 31. As an example, the connector 33 can be configured as a four-way pipe fitting.

[0059] Understandably, foam can be generated during the mixing of gas and liquid containing detergent. Solution tank 322 can be used to store cleaning liquid containing detergent, solution pump 321 is used to pump the cleaning liquid in solution tank 322 to foam pipeline 30, air pump 323 is used to supply gas to foam pipeline 30, and a foamer 324 has a foaming structure that allows gas and cleaning liquid to mix within the foamer 324 to generate foam, which can be sprayed from nozzle 31 onto the surface 2 to be cleaned. Thus, the cleaning device 1 provided in this application can achieve a point-spray foam mode.

[0060] Understandably, the solution pump 321 can be a peristaltic pump and / or a diaphragm pump, etc., and this application does not impose any limitations on it. The foaming structure includes honeycomb structures, filter structures, etc., and this application does not impose any limitations on it.

[0061] See Figure 3 In one embodiment, in the hot water spray mode or the room temperature water spray mode of the cleaning device 1, the solution pump 321 is in a closed state, and the air pump 323 can be in an operating state or a closed state. Specifically, when the air pump 323 and the solution pump 321 are in a closed state, the nozzle 31 can normally spray hot water or room temperature water. When the air pump 323 is in an operating state, the nozzle 31 can make the sprayed hot water or room temperature water into a fan shape under the action of gas, thereby increasing the coverage area of ​​the sprayed hot water or room temperature water, thereby improving the cleaning effect on the surface 2 to be cleaned.

[0062] See Figure 3 In one embodiment, the solution pump 321 and the air pump 323 are either in an operating state or an off state in either a water washing mode or a steam mode. When the solution pump 321 and the air pump 323 are in an off state, the cleaning device 1 can independently implement the water washing mode or the steam mode. When the solution pump 321 and the air pump 323 are in an operating state, the cleaning device 1 can combine the water washing mode with the spot spray foam mode, or combine the steam mode with the spot spray foam mode, as will not be elaborated further in this application.

[0063] See Figure 3 In one embodiment, the cleaning device 1 further includes at least the following cleaning modes: In the point spray mixing mode, the first inlet is connected to the heating interface, the second inlet is connected to the nozzle interface, the clean water source 11 and the solution pump 321 are in working state, so that the nozzle 31 outputs the mixture; In the point spray cleaning liquid mode, the first inlet is connected to the water outlet or heating interface, the second inlet is connected to the steam interface, the solution pump 321 is in working state, and the nozzle 31 outputs cleaning liquid. In point-spray gas mode, the first inlet is connected to the water outlet or heating interface, the second inlet is connected to the steam interface, the air pump 323 is in working state, and the nozzle 31 outputs gas.

[0064] It should be noted that in the spot spray mixing mode of cleaning device 1, nozzle 31 can output a mixture of room temperature water and cleaning solution. At this time, heating source 21 can be in working state to heat the mixture to form a hot mixture, so that nozzle 31 can spray out the hot mixture. Of course, heating source 21 can also be in a closed state, so that room temperature mixture can be output directly from nozzle 31 without heating, and this application does not impose any restrictions.

[0065] In the point-spray cleaning liquid mode of the cleaning device 1, the nozzle 31 can output cleaning liquid to the surface 2 to be cleaned, so as to dissolve dirt with the cleaning liquid. Understandably, the cleaning power of the mixed liquid is between that of room temperature water and cleaning liquid. Users can choose to point-spray room temperature water, point-spray hot water, point-spray mixed liquid, point-spray cleaning liquid or point-spray foam according to actual cleaning needs. This application does not impose any restrictions.

[0066] In the point-spray gas mode of cleaning device 1, nozzle 31 can spray gas. On the one hand, the gas output from nozzle 31 can blow off the crystals of foam that have solidified on nozzle 31, thereby preventing nozzle 31 from becoming clogged. On the other hand, the gas output from nozzle 31 can dry the liquid traces on the surface 2 to be cleaned, thereby achieving immediate drying after mopping with cleaning device 1.

[0067] See Figure 4 In one embodiment, the clean water source 11 includes a clean water tank 111 and a clean water pump 112 connected between the clean water tank 111 and the water outlet 12, and a heating source 21 is connected between the clean water pump 112 and the water outlet 12.

[0068] It should be noted that the clean water tank 111 is used to store room temperature water. The clean water tank 111 can be detachably installed on the body of the cleaning equipment 1, so that the user can remove the clean water tank 111 to add water or to clean and maintain the clean water tank 111. The clean water pump 112 is connected between the clean water tank 111 and the water outlet 12. When the clean water pump 112 is working, it can guide the room temperature water in the clean water tank 111 to the water outlet 12, the heating pipe 20, or the foam pipe 30.

[0069] Understandably, the water pump 112 can be a peristaltic pump and / or a diaphragm pump, etc., and this application does not impose any restrictions.

[0070] See Figure 4In one embodiment, the cleaning device 1 can also control the first control valve 50 to alternately connect the water outlet 12 and the steam outlet 22. For example, within one minute, the first inlet is first connected to the water outlet, allowing the water pump 112 to operate continuously at a flow rate of 20 ml / min for 50 seconds, so that the water outlet 12 can continuously output room temperature water to wet the roller brush 40. Then, the first inlet is connected to the heating interface, allowing the water pump 112 to operate continuously at a flow rate of 100 ml / min for 10 seconds, so that the steam outlet 22 can continuously output water steam. This configuration, through the cyclical alternation of operation of the water outlet 12 and the steam outlet 22, allows the water pump 112 to operate at alternating high and low power, avoiding rapid heating of the water pump 112, balancing power, and extending the service life of the cleaning device 1.

[0071] See Figure 4 In one embodiment, the clean water line 10 also includes a liquid detector 13, which is connected between the clean water pump 112 and the heating source 21.

[0072] It should be noted that the liquid detector 13 can be used to detect whether there is liquid flowing in the pipeline. When the water pump 112 is in operation, if the liquid detector 13 detects that there is no liquid flowing in the pipeline, the liquid detector 13 will issue an audible and / or visual alarm and cause the control system of the cleaning equipment 1 to control the water pump 112 to shut down, so as to avoid dry burning and damage to the water pump 112.

[0073] Understandably, the alarm issued by the liquid detector 13 can prompt the user to check whether the clean water tank 111 is low on water. If there is enough liquid in the clean water tank 111, 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.

[0074] Compared to related technologies that only install a level detector in the clean water tank 111, 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 111 is empty and the time the clean water pump 112 drains the remaining water from 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 13 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 112 is working, the liquid detector 13 will directly alarm to remind the user, regardless of whether there is still liquid in the clean water tank 111, so as to further check the cleaning device 1 and avoid safety hazards caused by pipe blockage or other problems.

[0075] See Figure 4In one embodiment, the heating source 21 includes a heater connected between the clean water pump 112 and the outlet 12. Understandably, the heater is used to heat the liquid within the pipeline. The heater includes heating components capable of generating steam, such as boiler assemblies or heating rod assemblies; this application is not limited to these. The heating temperature of the heater can be adjusted according to the control system of the cleaning equipment 1, which will not be elaborated upon in this application.

[0076] See Figure 4 In one embodiment, the heating pipe 20 further includes a filter 23 connecting the heating source 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 23 before the steam outlet 22, so that the filter 23 can filter out impurities carried by the liquid flowing to the steam outlet 22, thus preventing clogging of the steam outlet 22.

[0077] See Figure 4 In one embodiment, the heating conduit 20 further includes a booster 24 communicating between the heating source 21 and the steam outlet 22. Understandably, the greater the pressure of the steam, the greater its penetrating power. The booster 24 can be used to pressurize the liquid / steam within the conduit, enabling the water vapor / mixed liquid steam 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 2 to be cleaned.

[0078] With this configuration, when the cleaning equipment 1 cleans the gaps in the ground, the deep fibers of the blanket, or the porous surface to be cleaned 2, the pressure can be increased by the booster 24 to increase the pressure of the steam ejected from the steam outlet 22, so that the cleaning equipment 1 can have sufficient impact force to clean the dirt deep in the surface to be cleaned 2, thereby improving the cleaning power of the cleaning equipment 1.

[0079] See Figure 5 In one embodiment, the cleaning device 1 further includes a third control valve 70 and a fourth control valve 80. The third control valve 70 has a third inlet communicating with the heating source 21, a water outlet communicating with the water outlet 12, and a valve interface communicating with the fourth control valve 80. The fourth control valve 80 has a fourth inlet communicating with the valve interface, a steam interface communicating with the steam outlet 22, and a nozzle interface communicating with the nozzle 31. The foam source 32 is connected between the nozzle interface and the nozzle 31. The third control valve 70 and the fourth control valve 80 are configured as follows: In water washing mode, the third inlet and the outlet are connected, the heating source 21 is in working or closed state, so that the outlet 12 outputs hot water or room temperature water. In steam mode, the third inlet is connected to the valve interface, and the fourth inlet is connected to the steam interface; In the point spray foam mode, the third inlet is connected to the water outlet or valve interface, and the fourth inlet is connected to the steam interface. In the hot water spray mode or the room temperature water spray mode, the third inlet is connected to the valve interface, and the fourth inlet is connected to the nozzle interface.

[0080] It should be noted that, Figure 5 The piping structure of the cleaning device 1 shown is the same as described above. Figure 2 The difference in the piping structure of cleaning device 1 in the embodiments is: Figure 5 The heating source 21 is positioned between the clean water source 11 and the third control valve 70.

[0081] With this configuration, in water washing mode, the third inlet of the third control valve 70 is connected to the water outlet. If both the clean water source 11 and the heating source 21 are in operation, the outlet 12 can also output hot water to wet the roller brush 40. If the clean water source 11 is in operation and the heating source 21 is off, the outlet 12 can output room temperature water to wet the roller brush 40. In other words, Figure 5 The cleaning device 1 shown is different from the aforementioned Figure 2 In the example of the cleaning device 1: in the water washing mode of the cleaning device 1, the water outlet 12 can output room temperature water or hot water.

[0082] In steam mode, both the clean water source 11 and the heating source 21 are in operation. The third inlet of the third control valve 70 is connected to the valve interface, allowing steam to enter the fourth control valve 80. The fourth inlet of the fourth control valve 80 is connected to the steam interface, allowing steam to be output from the steam outlet.

[0083] In the point-spray foam mode, with foam source 32 in operation, connecting the fourth inlet of the fourth control valve 80 to the steam interface prevents foam from flowing back into the heating pipe 20. At this time, the third inlet of the third control valve 70 is connected to the water outlet or valve interface; this application does not impose any restrictions on this.

[0084] In the hot water spray mode, the clean water source 11 and the heating source 21 are in operation. The third inlet is connected to the valve interface to conduct hot water to the fourth control valve 80. The fourth inlet is connected to the nozzle interface, so that the nozzle 31 can output hot water.

[0085] In the point-spray normal temperature water mode, the clean water source 11 is in working condition. The third inlet is connected to the valve interface, which can guide the unheated normal temperature water to the fourth control valve 80. The fourth inlet is connected to the nozzle interface, which enables the nozzle 31 to output normal temperature water.

[0086] Understandably, the third control valve 70 and the fourth control valve 80 can also be configured as three-way valves, and this application does not impose any restrictions.

[0087] See Figure 6 In one embodiment, the cleaning device 1 further includes a fifth control valve 90. The fifth control valve 90 has a fifth inlet connected to the heating source 21, a water outlet connected to the water outlet 12, a steam outlet connected to the steam outlet 22, and a nozzle outlet connected to the nozzle 31. The foam source 32 is connected between the nozzle 31 and the nozzle outlet. The fifth control valve 90 is configured such that: in water washing mode, the fifth inlet is connected to the water outlet, the heating source 21 is in a working state or a closed state, and the water outlet 12 outputs hot water or room temperature water; in steam mode, the fifth inlet is connected to the steam outlet; and in point spray foam mode, point spray hot water mode, or point spray room temperature water mode, the fifth inlet is connected to the nozzle outlet.

[0088] Understandably, the fifth control valve 90 can be configured as a four-way directional valve.

[0089] In water washing mode, the fifth inlet of the fifth control valve 90 is connected to the water outlet. If the clean water source 11 is in working condition and the heating source 21 is in a closed state, the water outlet 12 can output room temperature water to the roller brush 40. If both the clean water source 11 and the heating source 21 are in working condition, the water outlet 12 can output hot water to the roller brush 40.

[0090] In steam mode, the fifth inlet of the fifth control valve 90 is connected to the steam interface, and both the clean water source 11 and the heating source 21 are in working condition, so the steam outlet 22 can spray steam onto the dirt.

[0091] In point-spray foam mode, point-spray hot water mode, or point-spray room temperature water mode, the fifth inlet of the fifth control valve 90 is connected to the nozzle interface. If the clean water source 11 is in the working state and the heating source 21 and foam source 32 are in the closed state, the nozzle 31 can output room temperature water to the dirty area. If the clean water source 11 and heating source 21 are in the working state and the foam source 32 is in the working state, the nozzle 31 can output hot water to the dirty area. If the foam source 32 is in the working state and the clean water source 11 and heating source 21 are in the closed state, the nozzle 31 can output foam to the dirty area.

[0092] This setting Figure 6The cleaning device 1 can connect the water outlet 12, steam outlet 22, and nozzle 31 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. Simultaneously, Figure 6 The cleaning device 1 can also control the water outlet 12, steam outlet 22 and nozzle 31 respectively through the fifth control valve 90, 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.

[0093] In one embodiment, for ease of understanding, this application uses a floor scrubber as an example to illustrate the cleaning device 1. The cleaning device 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 40 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 device 1. A clean water tank 111 can be installed on the handheld device to allow the user to remove the clean water tank 111 for replenishment or cleaning and maintenance. A solution tank 322 can be installed in the handheld device or the floor brush housing; this application is not limited to this. A clean water pump 112 and a solution pump 321 can be installed in the floor brush housing. A water outlet 12 can be connected to the floor brush housing and oriented towards the roller brush 40. A steam outlet 22 and a nozzle 31 are respectively connected to the floor brush housing and located on the upper and lower sides of the roller brush 40. Figure 7 and Figure 8 Examples can be given to illustrate the two pipe connection methods when cleaning equipment 1 is a floor scrubber.

[0094] In this design, nozzle 31 is positioned above roller brush 40, and steam outlet 22 is positioned below roller brush 40. This arrangement ensures that the distance between steam outlet 22 and the surface to be cleaned 2 is less than the distance between nozzle 31 and the surface to be cleaned 2. In other words, the proximity of steam outlet 22 to the surface to be cleaned allows the steam emitted from steam outlet 22 to directly act on the surface to be cleaned 2 with sufficient temperature and pressure, preventing the steam or mixed liquid steam from losing temperature and pressure due to a long transport path, thus avoiding a reduction in the cleaning effect of the steam. Simultaneously, the position of nozzle 31 above roller brush 40 allows for a larger spray range, increasing the coverage of dirt and improving the cleaning efficiency of cleaning equipment 1. Furthermore, the arrangement of nozzle 31 and steam outlet 22 does not interfere with the water outlet 12 supplying water to roller brush 40, ensuring the normal operation of roller brush 40.

[0095] In one embodiment, the nozzle 31 can be used to spray liquid onto dirt at a fixed point and / or in a quantitative manner. The spray range and spray force of the nozzle 31 can be adjusted according to the user's needs, which is not set in this application.

[0096] The technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings. All modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
