One end of the return water branch is connected to the outlet pipe, and the other end is connected to the return port of the heater. When the flow control unit connects the return port and the outlet pipe through the return water branch, the cooler cleaning medium in the outlet pipe can flow back to the heating chamber of the heater through the return water branch. This cooler cleaning medium helps cool the heating chamber, preventing premature triggering of the voltage reduction logic due to a rapid temperature rise. This allows the heater to heat up at a uniform rate, extending the time the heater operates at high power, thus improving the hot water output efficiency of the floor brush assembly and the user experience. Simultaneously, the cooler cleaning medium in the outlet pipe can be reused, improving the water-saving performance of the floor brush assembly and increasing the amount of hot water output.

[0029] In routine household cleaning, to effectively remove stubborn stains from floors, cleaning equipment with high-temperature cleaning functions is used to soften the stains, thus accelerating the removal process. However, in these technologies, a certain amount of cold water remains in the pipes after using the high-temperature cleaning function. When the high-temperature cleaning function is restarted, the equipment needs to wait for this residual cold water to drain before it can heat the roller brush, impacting the user experience.
[0030] To address the aforementioned technical problems, this application provides a floor brush assembly and a cleaning device.
[0031] Cleaning equipment can be floor scrubbers. For example, cleaning equipment can be fully automatic floor scrubbers, semi-automatic floor scrubbers, walk-behind floor scrubbers, ride-on floor scrubbers, etc.
[0032] The cleaning equipment is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a floor, wall, or the surface of an object to be cleaned with different degrees of roughness. The embodiments of this application do not specifically limit the type of surface to be cleaned.
[0033] Please see Figure 1 The cleaning device 100 provided in this application may include a floor brush assembly 110 and a body 120. The floor brush assembly 110 is connected to the body 120. The floor brush assembly 110 is rotatably connected to the bottom of the body 120. During cleaning, the user can hold the body 120 and push it to move the floor brush assembly 110 across the surface to be cleaned, allowing it to travel to different areas for cleaning.
[0034] Please continue reading. Figure 1The floor brush assembly 110 provided in this application may include a floor brush body 9 and a roller brush 1. The floor brush body 9 serves as the main support structure of the floor brush assembly 110. The roller brush 1 is rotatably connected to the floor brush body 9. During operation, the roller brush 1 can be driven to rotate at high speed by a motor installed inside it, causing the roller brush 1 to contact and rub against the surface to be cleaned, thus cleaning the surface.
[0035] The outer side of the roller brush 1 may be provided with bristles or sponge, so as to scrub the ground during the rotation of the roller brush 1 and carry up the wastewater after cleaning.
[0036] The brush body 9 can also be connected to wheels. Along the travel direction of the brush assembly 110, the roller brush 1 can be mounted at the front end of the brush unit, and the wheels can be mounted at the rear end of the brush body 9. This facilitates control of the travel direction of the brush assembly 110 and helps maintain its balance during travel. Furthermore, the roller brush 1 can preferentially contact the surface to be cleaned, and the absence of obstructions in front of the roller brush 1 facilitates effective cleaning.
[0037] Please see Figures 2-4 The floor brush assembly 110 may also include a heater 2. The heater 2 may have a heating chamber. The heating chamber may have an outlet. The heating chamber can heat the cleaning medium located within the heating chamber, and the heated cleaning medium can flow out of the heating chamber from the outlet.
[0038] The floor brush assembly 110 may include a liquid outlet pipe 3. The inlet end of the liquid outlet pipe 3 may be connected to the outlet end to deliver the cleaning medium from the heating chamber to the roller brush 1. Specifically, the cleaning medium flowing out of the outlet of the heating chamber may flow into the liquid outlet pipe 3 from the inlet end, and the cleaning medium in the liquid outlet pipe 3 may flow out of the liquid outlet pipe 3 from the outlet end of the liquid outlet pipe 3, spraying the cleaning medium onto the roller brush 1, so that the surface of the roller brush 1 can be covered with a high-temperature cleaning liquid, thereby enabling the floor brush assembly 110 to effectively clean stubborn stains on the surface to be cleaned, which is beneficial to improving the cleaning effect of the cleaning equipment 100.
[0039] The floor brush assembly 110 may include a return water branch 4. The heating chamber may have a return port. One end of the return water branch 4 may be connected to the outlet pipe 3. The other end of the return water branch 4 may be connected to the return port. Specifically, the cleaning medium in the outlet pipe 3 can flow through the return water branch 4 to the return port, and then flow back into the heating chamber through the return port.
[0040] The floor brush assembly 110 may also include a flow path control unit 5. The flow path control unit 5 can be used to connect or disconnect the return port from the outlet pipe 3 via the return water branch 4. Specifically, when the flow path control unit 5 connects the return port to the outlet pipe 3 via the return water branch 4, the cleaning medium in the outlet pipe 3 can directly flow through the return water branch 4 to the return port, and then flow from the return port into the heating chamber, where it is heated together with the cleaning medium in the heating chamber. When the flow path control unit 5 disconnects the return port from the outlet pipe 3 via the return water branch 4, the cleaning medium in the outlet pipe 3 cannot flow into the heating chamber.
[0041] The process of restarting the high-temperature cleaning function of the floor brush assembly 110 provided in this application is described below: The flow path control unit 5 connects the return port to the outlet pipe 3 via the return water branch 4, allowing the cooler cleaning medium in the outlet pipe 3 to flow back to the return port via the return water branch 4. To balance safety and lifespan, the heater 2 employs a voltage reduction power supply mode, applying a higher voltage upon startup and gradually reducing it during subsequent heating stages. This prevents overheating of the heater 2, extending its lifespan and overall operating time. When the heater 2 starts, a higher voltage is applied for rapid heating to produce hot water. However, this power supply logic introduces a problem: if the heating rate is too fast, the control program must quickly reduce the voltage of the heater 2, causing a decrease in its power and reducing its hot water output efficiency. At this point, the cooler cleaning medium flowing from the return port to the heating chamber of the heater 2 is cooled by water spraying to prevent a rapid temperature rise within the heating chamber, thus avoiding premature triggering of the voltage reduction power supply logic. This allows the heater 2 to achieve a uniform heating rate, extending its high-power operation time and improving the heating efficiency of the floor brush assembly 110.
[0042] In this application, the temperature of the roller brush 1 can be increased from 35°C to over 40°C compared to the temperature of the roller brush in the related technology, and the output efficiency of the cleaning medium is also increased by about 15%.
[0043] According to the embodiments of this application, the floor brush assembly 110 has a return water branch 4, one end of which is connected to the outlet pipe 3, and the other end is connected to the return port of the heater 2. When the flow control unit 5 connects the return port and the outlet pipe 3 through the return water branch 4, the cooler cleaning medium in the outlet pipe 3 can flow back to the heating chamber of the heater 2 through the return water branch 4. The incoming cooler cleaning medium can cool the heating chamber, which helps to avoid the problem of prematurely triggering the voltage reduction power supply logic due to the temperature rising too quickly in the heating chamber. This allows the heater 2 to achieve a uniform temperature rise during the heating process, thereby extending the time that the heater 2 operates at high power, improving the hot water output efficiency of the floor brush assembly 110 and the user experience. At the same time, the cooler cleaning medium on the outlet pipe 3 can also be reused, which helps to improve the water-saving performance of the floor brush assembly 110 and also helps to increase the amount of hot water output by the floor brush assembly 110. In addition, it can also achieve zero cold water in the floor brush assembly 110 and help improve the speed at which the floor brush assembly 110 outputs hot water.
[0044] Please continue reading. Figures 2-4 In some embodiments, the flow path control unit 5 may include an inlet, an outlet, and a return port. The outlet can be used to provide cleaning medium to the roller brush 1. The outlet is switched with one of the inlet and the return port. The flow path control unit 5 is connected in series with the liquid outlet line 3 through the inlet and the outlet, and the return port is connected to the return water branch line 4. Specifically, when the outlet is connected to the inlet, the outlet and the return port are in a closed state, and the cleaning medium in the heating chamber can flow from the outlet to the inlet of the flow path control unit 5, and then from the inlet to the outlet, providing cleaning medium to the roller brush 1 through the outlet. When the outlet is connected to the return port, the inlet and the outlet are in a closed state, and the lower temperature cleaning medium in the liquid outlet line 3 can flow through the return port to the return water branch line 4, and then from the return water branch line 4 back to the heating chamber through the return outlet.
[0045] This configuration facilitates the flow control unit 5's control of the connection between the return water branch 4 and the outlet pipe 3 and the heater 2. This allows the flow control unit 5 to flexibly adjust the flow direction of the cleaning medium, simplifying the control method and thus reducing the manufacturing cost of the floor brush assembly 110. It also enhances the flexibility of the flow control unit 5. Furthermore, the compact structure of the flow control unit 5 helps save installation space, thereby optimizing the structural layout of the floor brush assembly 110.
[0046] It should be noted that the flow path control unit 5 can also control only the opening or closing of the return water branch 4. The connection between the outlet of the heating chamber and the liquid outlet pipe 3 can be controlled by another control unit.
[0047] Please continue reading. Figures 2-4 In some embodiments, the flow path control unit 5 can be a three-way reversing solenoid valve. This configuration helps to improve the response speed and reliability of the floor brush assembly 110 control.
[0048] Please continue reading. Figures 2-4 In some embodiments, the floor brush assembly 110 may also include a one-way valve 41. The one-way valve 41 is connected in series with the return water branch 4. The one-way valve 41 allows the cleaning medium to flow unidirectionally from the outlet line 3 to the heating chamber. This helps prevent the cleaning medium from flowing back from the heating chamber to the outlet line 3, thereby avoiding the problem of the floor brush assembly 110 malfunctioning due to the backflow of the cleaning medium, and improving the stability and reliability of the floor brush assembly 110 operation.
[0049] Please continue reading. Figures 2-4 In some embodiments, the floor brush assembly 110 may further include a first pump body 42. The first pump body 42 is connected in series with the return water branch 4. Thus, when the return port is connected to the outlet pipe 3 through the return water branch 4, the first pump body 42 can provide power support to pump the cleaning medium with a lower temperature in the outlet pipe 3 into the return water branch 4, thereby helping to ensure the smooth flow of the cleaning medium in the return water branch 4, and thus helping to ensure the reliability of the operation of the floor brush assembly 110.
[0050] The first pump body 42 can be located between the one-way valve 41 and the flow path control unit 5. This facilitates maintenance of the first pump body 42 and also prevents backflow of the cleaning medium from impacting the first pump body 42, thereby helping to extend the service life of the first pump body 42.
[0051] It should be noted that the first pump body 42 may not be installed on the return water branch 4, and the cleaning medium in the return water branch 4 can flow into the heating chamber from the return liquid port by gravity.
[0052] Please continue reading. Figures 2-4 In some embodiments, the floor brush assembly 110 may also include a water storage tank. The water storage tank is connected in series with the return water branch 4. Thus, by providing a water storage tank, the cleaning medium flowing from the outlet pipe 3 into the return water branch 4 can be temporarily stored, which helps to balance the flow path in the return water branch 4 and avoid temperature fluctuations in the heating chamber caused by uneven flow of the cleaning medium. Simultaneously, the water storage tank can also directly store the cleaning medium in the outlet pipe 3 after the floor brush assembly 110 completes its high-temperature cleaning function, thereby helping to reduce leakage problems in the floor brush assembly 110.
[0053] Please continue reading. Figures 2-4 In some embodiments, the floor brush assembly 110 may also include a clean water tank 6. The clean water tank 6 can be used to store cleaning media.
[0054] The floor brush assembly 110 may also include a mixer 31. The mixer 31 is connected to the clean water tank 6 via a first clean water supply line 7. Thus, the mixer 31 can access cleaning media from the clean water tank 6 via the first clean water supply line 7.
[0055] The mixer 31 can be connected in series with the liquid outlet line 3, and the liquid outlet line 3 is connected to the mixer 31. Specifically, the cleaning medium flowing out of the outlet of the heating chamber can first flow into the mixer 31, mix with the cleaning medium provided from the first clean water supply line 7, and then flow out of the mixer 31 to the liquid outlet line 3.
[0056] For example, the mixer 31 may have a mixing chamber. The mixing chamber may have a first inlet, a second inlet, and a first outlet. The first inlet may be connected to a first clean water supply line 7, the second inlet may be connected to the outlet of the heating chamber, and the first outlet may be connected to the inlet of the liquid outlet line 3. Thus, the cleaning medium provided by the first clean water supply line 7 flowing in from the first inlet can be mixed with the steam provided by the heater 2 flowing in from the second inlet in the mixing chamber, and the mixed cleaning medium flows out from the first outlet to the liquid outlet line 3.
[0057] For example, a three-way directional valve 33 can be installed on the pipeline between the outlet of the heating chamber and the mixer 31. The three-way directional valve 33 is used to control the opening and closing of the pipeline between the outlet and the mixer 31. Thus, the amount of high-temperature cleaning medium flowing into the mixer 31 can be controlled by the three-way directional valve 33, so that the temperature of the cleaning medium output by the mixer 31 can be adjusted according to actual needs, thereby making the cleaning equipment 100 applicable to more scenarios and improving the versatility of the cleaning equipment 100.
[0058] Please continue reading. Figures 2-4 In some embodiments, the heating chamber may have an inlet. The floor brush assembly 110 also includes a reversing element having a first reversing valve port, a second reversing valve port, and a third reversing valve port. The first reversing valve port is connected to the clean water tank 6. A scale inhibitor 61 and a photoelectric sensor 62 may be installed on the pipeline between the first reversing valve port and the clean water tank 6. The scale inhibitor 61 reduces scale in the clean water medium. The photoelectric sensor 62 can be used to detect the amount of water in the clean water tank 6.
[0059] The second reversing valve port is connected to the heater 2 via the second clean water supply line 8, and the third reversing valve port is connected to the mixer 31 via the first clean water supply line 7. The third reversing valve port is switched with one of the first and second reversing valve ports. Specifically, when the first and third reversing valve ports are connected, the cleaning medium in the clean water tank 6 can flow to the mixer 31 through the first clean water supply line 7, mix with the high-temperature cleaning medium flowing out of the heating chamber, and then spray it onto the roller brush 1. When the first and second reversing valve ports are connected, the cleaning medium in the clean water tank 6 enters the heating chamber through the inlet of the second clean water supply line 8, providing sufficient cleaning medium for the heater 2.
[0060] For example, the reversing element can be a three-way solenoid valve.
[0061] For example, a third pump and a pressure relief valve 81 can be connected in series in the pipeline between the reversing component and the inlet of the heater 2. The third pump can then pump the cleaning medium from the clean water tank 6 into the heating chamber through the second clean water supply pipeline 8. The pressure relief valve 81 protects the heater 2, thereby improving the operational safety of the floor brush assembly 110.
[0062] Please continue reading. Figures 2-4 For example, the floor brush assembly 110 may also include a second pump body 71. The second pump body 71 is disposed on the first clean water supply line 7. Thus, the second pump body 71 facilitates the pumping of water from the clean water tank 6 into the mixer 31. It also facilitates the maintenance of the second pump body 71.
[0063] Please continue reading. Figures 2-4 In some embodiments, the floor brush assembly 110 may further include a first detection element. The first detection element is disposed on the liquid outlet pipe 3 and is used to detect whether there is cleaning medium in the liquid outlet pipe 3. This allows the cleaning medium with a lower temperature in the liquid outlet pipe to flow entirely into the return water branch pipe 4, thereby helping to prevent residual cleaning medium from affecting the temperature of the new cleaning medium in the liquid outlet pipe, and thus helping to ensure the cleaning effect of the floor brush assembly 110.
[0064] It should be noted that the first detection element may not be provided on the floor brush assembly 110. By limiting the suction time of the first pump body 42, the first pump body 42 can ensure that the cleaning medium with a lower temperature remaining in the liquid outlet pipe 3 can be drawn into the return water branch 4, thereby helping to reduce the manufacturing cost of the floor brush assembly 110.
[0065] Please continue reading. Figures 2-4In some embodiments, the floor brush assembly 110 may further include a water distributor 32, which may be connected to the outlet end of the liquid outlet pipe 3. The water distributor 32 may have multiple spray nozzles, which may be directly opposite the roller brush 1. Thus, the water distributor 32 can evenly distribute the cleaning medium delivered from the liquid outlet pipe 3 to each spray nozzle, thereby achieving full coverage of the roller brush 1 and improving the cleaning effect of the floor brush assembly 110.
