A heater can be used to heat the room-temperature water in the water pipes to generate steam, allowing the equipment to output steam for sterilizing and disinfecting the surfaces, thus providing a steam cleaning mode.

[0019] With this configuration, the cleaning equipment provided in this application only needs a clean water pump as a power source to work with the heater to meet the usage requirements of the cleaning equipment to output clean water and water vapor. This simplifies the pipeline structure of the cleaning equipment, reduces the production cost and maintenance difficulty of the cleaning equipment, and improves the user experience.

[0039] 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. In these technologies, cleaning equipment can output not only water but also steam, using the steam to sterilize and disinfect the surface being cleaned, thereby enhancing the cleaning effect. However, the piping used to output water and steam in these technologies is very complex, leading not only to high production costs but also to difficult maintenance and a poor user experience.

[0040] Based on this, this application provides a cleaning device that simplifies the pipeline connection structure while outputting clean water and water vapor, thereby reducing the production cost and maintenance difficulty of the cleaning device and improving the 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 cleaning machines, and robotic vacuum cleaners, and this application does not impose any limitations.

[0041] The cleaning equipment provided in this application will now be described in conjunction with the accompanying drawings.

[0042] See Figure 1 This application provides a cleaning device 1, including a clean water pipeline 10. The clean water pipeline 10 includes 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. A heater 21 is provided between the clean water pump 12 and the water outlet 13, enabling the cleaning device 1 to have a water washing mode and a steam mode. In the water washing mode, the clean water pump 12 is in operation. In the steam mode, both the clean water pump 12 and the heater 21 are in operation.

[0043] It should be noted that the cleaning device 1 can be used to clean surfaces to be cleaned, including different surfaces such as floors, kitchen countertops, or carpets; this application does not impose any limitations. The clean water tank 11 can be used to store clean water, and the clean water tank 11 can be detachably installed on the body of the cleaning device 1 to facilitate the user adding clean water or cleaning and maintenance of the clean water tank 11. 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 in the clean water tank 11 can be room temperature water, which can be used to wet the roller brush of the cleaning device 1 or dilute dirt on the surface to be cleaned.

[0044] The heater 21 can be used to heat the room temperature water in the clean water pipeline 10 to generate steam, enabling the cleaning equipment 1 to output steam and use the steam to sterilize and disinfect the surface to be cleaned. Understandably, the heater 21 includes a boiler assembly, allowing it to be connected between the clean water pump 12 and the outlet 13 to heat the room temperature water. The heater 21 also includes a heating wire, allowing it to be wrapped around the clean water pump 12 and the outlet 13 to heat the room temperature water. Understandably, the heater 21 can include any heating element capable of generating steam, such as a boiler assembly or a heating wire; this application is not limited to this.

[0045] With this configuration, during the use of the cleaning device 1 provided in this application, when the water pump 12 is in operation and the heater 21 is in the off state, the water outlet 13 can output room temperature water, enabling the cleaning device 1 to have a water washing mode. When the water pump 12 is in operation and the heater 21 is also in operation, the water outlet 13 can output water steam, enabling the cleaning device 1 to have a steam mode. Understandably, the water washing mode of the cleaning device 1 can be used to wet the roller brush or dilute dirt on the surface to be cleaned. The steam mode of the cleaning device 1 can be used to sterilize and disinfect the surface to be cleaned.

[0046] Understandably, cleaning equipment 1 in related technologies often requires separate water pumps and steam pumps to achieve the function of outputting clean water and steam, resulting in complex piping connections, high maintenance difficulty, and high costs. However, the cleaning equipment 1 provided in this application only needs a single clean water pump 12 as a power source to cooperate with the heater 21 to meet the needs of outputting room temperature water and steam, thereby simplifying the piping structure of the cleaning equipment 1, reducing production costs and maintenance difficulty, and improving the user experience.

[0047] Understandably, the water pump 12 can be a peristaltic pump and / or a diaphragm pump, etc., and this application does not impose any restrictions.

[0048] See Figure 2 In one embodiment, the cleaning device 1 further includes a steam outlet 22 connected to the heater 21. In water washing mode, the water outlet 13 outputs room temperature water. In steam mode, the steam outlet 22 outputs steam.

[0049] It should be noted that steam outlet 22 can be used to output the water vapor generated in the pipeline, allowing the water vapor and room temperature water generated by cleaning equipment 1 to flow out from different outlets. That is, water outlet 13 is used to output room temperature water and is no longer used to output water vapor. Understandably, there is a large temperature difference between water vapor and room temperature water. When water vapor and room temperature water share the same outlet, the outlet that has just discharged room temperature water will lower the temperature of the water vapor, making it impossible to maintain the stability of the water vapor output by cleaning equipment 1. Similarly, the residual heat of outlet 22, which has just discharged water vapor, will also heat the room temperature water, causing cleaning equipment 1 to output warm or hot water, thus affecting the cleaning effect of room temperature water. For example, when there are protein, starch, or blood stains on the surface to be cleaned, these stains will solidify when they come into contact with hot water, making them difficult to clean. In this case, room temperature water can be used for cleaning.

[0050] Thus, by adding a steam outlet 22 to the cleaning device 1 that is independent of the water outlet 13, the steam outlet 22 and the water outlet 13 can be used independently of each other, which can avoid mutual interference between the cleaning device 1 in different cleaning modes, thereby ensuring the cleaning effect of the cleaning device 1 in different modes.

[0051] See Figure 3 In one embodiment, the cleaning device 1 further includes a nozzle 30 connected between the heater 21 and the steam outlet 22, enabling the cleaning device 1 to have both a hot water spray mode and a room temperature water spray mode. In the hot water spray mode, the water pump 12 and the heater 21 are both operational, causing the nozzle 30 to spray hot water. In the room temperature water spray mode, the water pump 12 is operational, causing the nozzle 30 to spray room temperature water.

[0052] It should be noted that heater 21 can provide different heating temperatures, enabling the room temperature water in the clean water pipe 10 to be heated into hot water or steam. Understandably, the heating temperature of heater 21 can be adjusted according to the control system of cleaning equipment 1, which will not be elaborated in this application.

[0053] With this configuration, the cleaning device 1 can also output hot or room temperature water through the nozzle 30. For example, when the nozzle 30 is open and both the water pump 12 and the heater 21 are in operation, the nozzle 30 can output hot water. When the water pump 12 is in operation and the heater 21 is off, the nozzle 30 can output room temperature water.

[0054] As an example, the cleaning device 1 typically also includes a roller brush for wiping the surface to be cleaned. In this case, the water outlet 13 of the cleaning device 1 can be oriented towards the roller brush, and the steam outlet 22 and nozzle 30 of the cleaning device 1 can be oriented towards the surface to be cleaned. With this configuration, the cleaning device 1 can output room temperature water to the roller brush through the water outlet 13 in a water washing mode, allowing the user to wipe away dirt from the surface using the moistened roller brush. The cleaning device 1 can also output steam to the surface to be cleaned through the steam outlet 22 in a steam mode, allowing the user to use the steam to sterilize and disinfect the surface. The cleaning device 1 can also directly spray room temperature water onto the surface to be cleaned through the nozzle 30 in a spot spray mode, allowing the user to use the room temperature water to dilute protein-based or blood-stained dirt. The cleaning device 1 can also directly spray hot water onto the surface to be cleaned through the nozzle 30 in a hot water spray mode, allowing the user to use the hot water to accelerate the dissolution of oil-based dirt.

[0055] In one embodiment, when the cleaning device 1 has a water outlet 13, a steam outlet 22, and a nozzle 30, the distance between the steam outlet 22 and the surface to be cleaned can be set to be less than the distance between the nozzle 30 and the surface to be cleaned. For example, the nozzle 30 and the steam outlet 22 can be located on the upper and lower sides of the roller brush of the cleaning device 1, respectively. Specifically, the nozzle 30 is located above the roller brush, and the steam outlet 22 is located below the roller brush.

[0056] This configuration, with the steam outlet 22 positioned close to the surface to be cleaned, ensures that the steam emitted from the outlet acts directly on the surface with sufficient temperature and pressure. This prevents the steam from losing temperature and pressure over a long transport path, thus maintaining its cleaning effectiveness. Simultaneously, the nozzle 30'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 30 and steam outlet 22 does not interfere with the water outlet 13's flow to the roller brush, ensuring its proper functioning.

[0057] 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 1. 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 clean water pump 12 and a heater 21 can be installed inside 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 30 are respectively connected to the floor brush housing and located on the upper and lower sides of the roller brush.

[0058] See Figure 4 In one embodiment, to facilitate the cleaning device 1 in implementing various cleaning modes, the cleaning device 1 further includes a first control valve 40 and a second control valve 50. The first control valve 40 has a clean water inlet connected to the clean water pump 12, a water outlet connected to the water outlet 13, and a heating interface connected to the heater 21. The second control valve 50 has a heating inlet connected to the heater 21, a steam interface connected to the steam outlet 22, and a nozzle interface connected to the nozzle 30. The first control valve 40 and the second control valve 50 are respectively configured as follows: in the water washing mode, the clean water inlet is connected to the water outlet, and the heating inlet is connected to the steam interface or the nozzle interface; in the steam mode, the clean water inlet is connected to the heating interface, and the heating inlet is connected to the steam interface; in the point-spray hot water mode or the point-spray room temperature water mode, the clean water inlet is connected to the heating interface, and the heating inlet is connected to the nozzle interface.

[0059] It should be noted that the first control valve 40 and the second control valve 50 can each be a three-way directional valve. The first control valve 40 can be used to divert room temperature water supplied by the clean water pipeline 10 to the outlet 13 or the heater 21. The second control valve 50 can be used to divert liquid in the heater 21 to the steam outlet 22 or the nozzle 30.

[0060] As an example, in the water washing mode, the clean water inlet and outlet are connected, allowing the room temperature water supplied by the clean water pipe 10 to flow to the outlet 13, and then from the outlet 13 to the roller brush, thereby wetting the roller brush. At this time, the room temperature water supplied by the clean water pipe 10 will not flow to the heater 21, so the heating inlet can be connected to the steam interface or the nozzle interface. The steam outlet 22 will not output water vapor, and the nozzle 30 will not spray hot water or room temperature water. The water washing mode of the cleaning device 1 can be used independently.

[0061] In steam mode, the cleaning inlet and heating interface are connected, allowing room temperature water supplied by the clean water pipe 10 to enter the heater 21 and be heated to form steam. The heating inlet and steam interface are connected, allowing steam to be output from the steam outlet 22 to the surface to be cleaned, thus sterilizing and disinfecting the dirt on the surface. At this time, the steam mode of the cleaning device 1 can be used independently.

[0062] In either the hot water or room temperature water spray mode, the clean water inlet and the heating inlet are connected, allowing room temperature water supplied by the clean water pipe 10 to enter the heater 21. When the heater 21 is operational, the room temperature water is heated to form hot water, and the heating inlet is connected to the nozzle inlet, allowing the nozzle 30 to spray hot water onto the surface to be cleaned. In this mode, the hot water spray mode of the cleaning device 1 can be used independently. When the heater 21 is off, room temperature water can be output directly from the nozzle 30 without heating, allowing the nozzle 30 to spray room temperature water onto the surface to be cleaned. In this mode, the room temperature water spray mode of the cleaning device 1 can also be used independently.

[0063] Therefore, this application allows the heater 21 to be connected to the clean water pipeline 10 via the first control valve 40, and the nozzle 30 to be connected between the heater 21 and the steam outlet 22 via the second control valve 50. This enables the water outlet 13, steam outlet 22, and nozzle 30 to be used independently, thus flexibly coordinating with various cleaning modes of the cleaning equipment 1. Furthermore, the cleaning equipment 1 provided by this application can achieve pipeline 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.

[0064] See Figure 5 In one embodiment, the cleaning device 1 further includes a filter 23 communicating between the clean water tank 11 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.

[0065] Understandably, the nozzle 30's outlet orifice is usually designed to be small in diameter. To prevent the nozzle 30 from becoming clogged, the filter 23 can also be connected between the heater 21 and the heating inlet.

[0066] See Figure 5 In one embodiment, the cleaning device 1 further includes a booster 24 communicating between the clean water tank 11 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 pipe, enabling the 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 to be cleaned.

[0067] 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 booster 24 can be used 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.

[0068] See Figure 5 In one embodiment, the cleaning device 1 further includes a liquid detector 14 communicating between the clean water tank 11 and the heater 21. As an example, the liquid detector 14 may be connected between the clean water pump 12 and the clean water inlet of the first control valve 40.

[0069] It should be noted that the liquid detector 14 can be used to detect whether liquid is flowing in the pipeline. When the water pump 12 is in operation, if the liquid detector 14 detects no liquid flow in the pipeline, it will issue an audible and / or visual alarm and cause the control system of the cleaning equipment 1 to shut down the water pump 12 to prevent it from being damaged due to dry burning. Understandably, the alarm issued by the liquid detector 14 can prompt the user to check whether the water tank 11 is low on water. If there is sufficient liquid in the water tank 11, 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.

[0070] 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 14 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 is working, the liquid detector 14 will directly alarm to remind the user, regardless of whether there is still liquid in the clean water tank 11, so as to further check the cleaning device 1 and avoid safety hazards caused by pipe blockage or other problems.

[0071] See Figure 6In one embodiment, to further enrich the cleaning modes of the cleaning device 1, the cleaning device 1 also includes a first solution pump 60 connected between the clean water tank 11 and the heater 21, and a first solution tank 70 connected to the first solution pump 60. At least one of the clean water pump 12 and the first solution pump 60 is in operation, so that the cleaning device 1 also has a mixed liquid water washing mode and a mixed liquid steam mode. In the mixed liquid water washing mode, the clean water pump 12 and the first solution pump 60 are in operation. In the mixed liquid steam mode, the clean water pump 12, the first solution pump 60, and the heater 21 are all in operation.

[0072] It should be noted that the first solution tank 70 can be used to store various cleaning solutions with cleaning functions, such as oil stain cleaner, floor cleaner, fabric cleaner, carpet cleaner, glass cleaner, disinfectant cleaner, or mold remover. The first solution pump 60 can deliver the cleaning solution in the first solution tank 70 to the clean water pipeline 10. Understandably, the first solution pump 60 can be a peristaltic pump and / or a diaphragm pump, etc., and this application does not impose any limitations.

[0073] The first solution pump 60 is connected between the clean water tank 11 and the heater 21 via a pipe joint. When the first solution pump 60 and the clean water pump 12 are in operation, the clean water in the clean water tank 11 flows into the clean water pipeline 10 via the clean water pump 12, and the cleaning solution in the first solution tank 70 is also input into the clean water pipeline 10 via the first solution pump 60, so that the clean water and the cleaning solution can mix to form a mixture.

[0074] When the clean water inlet and outlet of the first control valve 40 are connected, the mixed liquid can flow out from the outlet 13, so that the cleaning equipment 1 has a mixed liquid washing mode.

[0075] When the clean water inlet of the first control valve 40 is connected to the heating interface, and the heating inlet of the second control valve 50 is connected to the steam interface, the mixture can be heated by the heater 21 to form mixture steam, so that the steam outlet 22 can output mixture steam.

[0076] When the clean water inlet of the first control valve 40 is connected to the heating interface, and the heating inlet of the second control valve 50 is connected to the nozzle interface, the mixed liquid can be sprayed from the nozzle 30. Specifically, if the heater 21 is in the off state, the nozzle 30 can spray the room temperature mixed liquid, giving the cleaning device 1 a point-spray mode for the room temperature mixed liquid. If the heater 21 is in the working state, the nozzle 30 can spray the hot mixed liquid, giving the cleaning device 1 a point-spray mode for the hot mixed liquid.

[0077] See Figure 7In one embodiment, to further enrich the cleaning modes of the cleaning device 1, the cleaning device 1 also includes a foam source 80 connected between the nozzle interface and the nozzle 30. The foam source 80 is used to output foam to the nozzle 30, so that the cleaning device 1 also has a spot spray foam mode.

[0078] It should be noted that the cleaning device 1 can also spray foam onto the surface to be cleaned through the nozzle 30. The foam source 80 generates foam during operation, allowing it to be sprayed onto the surface to be cleaned through the nozzle 30. The foam dissolves dirt on the surface, thereby improving the cleaning effect. Understandably, the foam has low fluidity and can remain on the dirty surface for a longer period, increasing the persistence of dirt decomposition and thus enhancing the cleaning effect.

[0079] Thus, the cleaning device 1 provided in this application can output room temperature water to the roller brush through the water outlet 13 for a water washing mode, output a mixed liquid to the roller brush through the water outlet 13 for a mixed liquid water washing mode, output water vapor or mixed liquid steam to the surface to be cleaned through the steam outlet 22 for a steam mode, and spray foam, hot water, room temperature water, room temperature mixed liquid, or hot mixed liquid onto the surface to be cleaned through the nozzle 30 in multiple spraying modes. Therefore, the cleaning device 1 provided in this application can have multiple functions, realize multi-purpose use, and enable users to select the corresponding cleaning mode in various complex cleaning scenarios to improve the user experience.

[0080] It is understood that the various cleaning modes of the cleaning equipment 1 provided in this application, including water washing mode, mixed liquid water washing mode, water steam mode, mixed liquid steam mode, spot spray foam mode, spot spray hot water mode, spot spray room temperature water mode, spot spray room temperature mixed liquid mode, and spot spray hot mixed liquid mode, can be used independently or in combination, and this application does not impose any restrictions. For example, when there is residual dirt on the surface to be cleaned, the user can use the nozzle 30 of the cleaning equipment 1 to spray foam onto the dirt to pre-dissolve the dirt, so that the dirt can be cleaned by the roller brush later. If there are still traces of dirt on the surface to be cleaned, water steam can be sprayed from the steam outlet 22 for further sterilization and disinfection, thereby improving the cleaning effect of the cleaning equipment 1. In other words, the spot spray foam mode of the cleaning equipment 1 can be used in combination with the water steam mode, and the spot spray foam mode can also be used in combination with the water washing mode, etc., thereby improving the cleaning effect of the cleaning equipment 1. It is understood that the user can combine various cleaning modes according to the usage needs, and this application will not elaborate on this.

[0081] See Figure 8In one embodiment, to enable the cleaning device 1 to spray foam in spots, the foam source 80 includes a second solution pump 81, a second solution tank 82, an air pump 83, a foamer 84, and a connector 85. The connector 85 connects the nozzle interface and the nozzle 30. The second solution pump 81, the air pump 83, and the foamer 84 are respectively connected to the connector 85. The second solution tank 82 is connected to the second solution pump 81, and the nozzle 30 is connected to the foamer 84. In spot-spray foam mode, the solution pump and the air pump 83 are operational.

[0082] It should be noted that the connector 85 can be configured as a pipe fitting or a control valve to facilitate the connection of the foam source 80 between the nozzle interface and the nozzle 30. As an example, the connector 85 can be configured as a four-way pipe fitting.

[0083] Understandably, foam can be generated during the mixing of gas and liquid containing detergent. The second solution tank 82 can be used to store the cleaning liquid containing detergent, the second solution pump 81 is used to pump the cleaning liquid in the second solution tank 82 into the foam pipeline, the air pump 83 is used to supply gas to the foam pipeline, and the foamer 84 has a foaming structure that allows the gas and cleaning liquid to mix within the foamer 84 to generate foam, which can be sprayed from the nozzle 30 onto the surface to be cleaned. Thus, the cleaning device 1 provided in this application can achieve a point-spray foam mode.

[0084] Understandably, the second solution pump 81 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.

[0085] See Figure 8 In one embodiment, when the second solution pump 81 and the clean water pump 12 are in operation, the nozzle 30 can also spray the mixed solution. When the second solution pump 81 is in operation and the clean water pump 12 is off, the nozzle 30 can also spray the cleaning solution. When the second solution pump 81 is off and the clean water pump 12 is in operation, the nozzle 30 can also spray room temperature water. When the second solution pump 81 is off and the clean water pump 12 and the heater 21 are in operation, the nozzle 30 can also spray hot water.

[0086] exist Figure 8 In the point-spray hot water mode or point-spray room temperature water mode of the cleaning device 1 shown, the air pump 83 can be in an active state or an off state. Specifically, when the air pump 83 is in an active state, the nozzle 30 can make the point-sprayed hot water or room temperature water into a fan shape under the action of gas, thereby increasing the coverage area of ​​the point-sprayed hot water or room temperature water by the nozzle 30, thereby improving the cleaning effect on the surface to be cleaned.

[0087] In addition, Figure 8In the cleaning device 1 shown, when the second solution pump 81 is off and the air pump 83 is working, the nozzle 30 can also spray gas. This configuration allows the gas output from the nozzle 30 to blow off any crystals of foam that have solidified on it, thus preventing clogging. Furthermore, the gas output from the nozzle 30 can dry any liquid residue on the surface to be cleaned, enabling the cleaning device 1 to dry the surface immediately after mopping.

[0088] See Figure 9 This application also provides another cleaning device 1, which differs from the cleaning device 1 described above in that... Figure 9 The water outlet 13 and steam outlet 22 of the cleaning device 1 shown can be used simultaneously. The following will discuss... Figure 9 The cleaning equipment 1 shown is further explained.

[0089] See Figure 9 In one embodiment, this application also provides another cleaning device 1, including a clean water pipeline 10, a heating pipeline 20, and a third control valve 90. The clean water pipeline 10 has 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 heating pipeline 20 has a heater 21 and a steam outlet 22 connected to the heater 21. The third control valve 90 is connected between the clean water pump 12 and the water outlet 13, and the third control valve 90 has a clean water connection port connected to the clean water pump 12, a water outlet connection port connected to the water outlet 13, and a heating connection port connected to the heater 21. The third control valve 90 is configured such that, in steam mode, the clean water connection port is connected to both the water outlet connection port and the heating connection port, causing the water outlet 13 to output room temperature water and the steam outlet 22 to output steam.

[0090] Understandably, in the steam mode of the cleaning device 1, the steam outlet 22 is capable of outputting water vapor. The temperature and pressure of the water vapor cause the temperature and pressure inside the heating pipe to be greater than the temperature and pressure inside the clean water pipe 10.

[0091] With this configuration, in the steam mode of the cleaning equipment 1, the third control valve 90 can simultaneously connect the water outlet 13 and the steam outlet 22. This allows the cleaning equipment 1 to use the water outlet 13 to relieve the working pressure of the steam outlet 22, thereby distributing the working pressure in the heating pipe 20 to the water outlet 13 of the clean water pipe 10. Pressure is released at the water outlet 13, preventing blockage of the heating pipe 20 or the steam outlet 22 of the cleaning equipment 1, and thus avoiding the risk of explosion.

[0092] In one embodiment, the cleaning device 1 can also control the third control valve 90 to alternately connect the water outlet 13 and the steam outlet 22. For example, within one minute, the clean water connection port of the third control valve 90 is first connected to the water outlet connection port, allowing the clean water pump 12 to operate continuously at a flow rate of 20 ml / min for 50 seconds, so that the water outlet 13 can continuously output room temperature water to wet the roller brush. Then, the clean water connection port is connected to the heating connection port, allowing the clean water pump 12 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 setting, through the cyclical alternation of operation of the water outlet 13 and the steam outlet 22, allows the clean water pump 12 to operate at alternating high and low power, avoiding rapid heating of the clean water pump 12, thus balancing the power and extending the service life of the cleaning device 1.

[0093] See Figure 10 In one embodiment, in order to alleviate the working pressure of the heating pipe 20 in steam mode, the cleaning device 1 provided in this application can control the flow rate of the heating pipe 20 to not exceed the flow rate of the clean water pipe 10 in steam mode.

[0094] Example 1: The cleaning device 1 provided in this application can have a heating pipe 20 with a diameter smaller than the clean water pipe 10. With this configuration, in steam mode, the flow rate of room temperature water to the outlet 13 can be greater than the flow rate to the heating pipe 20. This can alleviate the working pressure of the heating pipe 20 in steam mode, and also ensure that the room temperature water entering the heating pipe 20 is sufficiently heated to form steam, thereby improving steam generation efficiency and the cleaning effect of the cleaning device 1.

[0095] Example 2: To control the flow rate of the heating pipe 20 to not exceed the flow rate of the clean water pipe 10, the cleaning device 1 also includes a flow regulator 25 located in the heating pipe 20. This configuration allows the flow regulator 25 to limit the flow rate of ambient temperature water to the heating pipe 20 in steam mode, thereby controlling the flow rate of the heating pipe 20 to not exceed the flow rate of the clean water pipe 10. It is understood that the flow regulator 25 includes a throttle valve.

[0096] Example 3: To control the flow rate of the heating pipe 20 to not exceed the flow rate of the clean water pipe 10, the cleaning device 1 further includes a diversion structure 26, which connects the heater 21 and the steam outlet 22. With this configuration, in steam mode, the diversion structure 26 can be used to guide a portion of the liquid in the heating pipe 20 to the outside of the heating pipe 20, thereby reducing the flow rate in the heating pipe 20. For example, the diversion structure 26 can be a pipe fitting connected to the nozzle 30 to guide a portion of the liquid in the heating pipe 20 to the nozzle 30 for discharge.

[0097] Understandably, in order to alleviate the working pressure of the heating pipe 20 in steam mode, the cleaning device 1 may adopt at least one of the methods in Example 1, Example 2 and Example 3, and this application does not impose any restrictions.

[0098] See Figure 11 and Figure 12 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 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 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 can be installed in the handheld device or the floor brush housing; this application does not impose limitations. A clean water pump 12 and a solution pump 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 30 are respectively connected to the floor brush housing and located on the upper and lower sides of the roller brush. Figure 11 and Figure 12 Examples can be given to illustrate the two pipe connection methods when cleaning equipment 1 is a floor scrubber.

[0099] Thus, the cleaning device 1 provided by this application can have multiple cleaning modes, such as water washing mode, mixed liquid water washing mode, water steam mode, mixed liquid steam mode, spot spray foam mode, spot spray hot water mode, spot spray room temperature water mode, spot spray room temperature mixed liquid mode, or spot spray hot mixed liquid mode. Therefore, the cleaning device 1 provided by this application can have multiple functions, realize multi-purpose use, and enable users to select the corresponding cleaning mode in various complex cleaning scenarios, thereby improving the user experience.
