[0077] In this application, "M includes at least one of A, B, and C" means that M includes at least A, or M includes at least B, or M includes at least C. That is, M can include only A, only B, only C, or any combination of A, B, and C. Any combination of the described A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0078] As shown in Figure 1 The present disclosure provides a cleaning system. The cleaning system includes a base station 02 and a cleaning device 01. The cleaning device 01 can be an active cleaning device or a passive cleaning device. For example, the cleaning device 01 can be a scrubber, a robotic sweeper, a vacuum-mop all-in-one machine, etc., and the present disclosure does not specifically limit it.

[0079] The cleaning device 01 can be docked with the base station 02. The base station 02 can charge the cleaning device 01. In some embodiments, the base station 02 can also replenish water and / or clean the cleaning device 01. For example, the base station 02 can add water to the water tank of the cleaning device 01. For another example, the base station 02 can clean the components of the cleaning device 01 used for cleaning the ground. In some embodiments, the base station 02 can also suck out the dirt stored in the cleaning device 01. The present disclosure does not limit the specific form of the base station 02.

[0080] Taking the cleaning device 01 as a passive cleaning device as an example. For example, the cleaning device 01 can be a scrubber. As shown in Figure 1As shown, the cleaning device 01 can include a handheld part 03 and a brush head 04. The handheld part 03 can be connected with the brush head 04. The brush head 04 can be used to clean a surface to be cleaned. Wherein, an operator can move and / or operate the cleaning device 01 by holding the handheld part 03 to clean the surface to be cleaned by the brush head 04.

[0081] It should be noted that the cleaning device 01 described above is a scrubber, which is only one embodiment. Those skilled in the art should understand that the cleaning device 01 described above is also within the protection scope of the present disclosure when it is in other forms.

[0082] As shown, Figure 2 The brush head 04 can include a cleaning element 13 and a dirt suction pipe 2. The cleaning element 13 can be used to clean the surface to be cleaned.

[0083] The cleaning element 13 can be in contact with the surface to be cleaned for cleaning the surface to be cleaned. The cleaning element 13 can be a roller brush, but is not limited thereto. The cleaning element 13 can also be a brush bar, an edge brush, etc., which can be selected and set according to actual conditions, and all of these are within the protection scope of the present disclosure.

[0084] The dirt suction pipe 2 can be configured to suck dirt on the surface to be cleaned. That is, it can be understood that the dirt suction pipe 2 can suck dirt on the surface to be cleaned or the surface of the cleaning element 13 through high-speed flowing air.

[0085] In one embodiment, the opening of the dirt suction pipe 2 can be arranged opposite to the cleaning element 13 to facilitate the suction of dirt on the surface of the cleaning element 13. In addition, the opening of the dirt suction pipe 2 can be arranged opposite to the central region of the cleaning element 13 to make the dirt suction pipe 2 have the same suction capacity for dirt located at both ends of the cleaning element 13, thereby improving the suction effect of the dirt suction pipe 2 on the dirt on the surface of the cleaning element 13.

[0086] In some embodiments, in order to obtain better cleaning effect, the opening of the dirt suction pipe 2 can be arranged at or close to the middle position of the brush head 04. The dirt suction pipe 2 can extend from the opening of the dirt suction pipe 2 to a dirt collection site (dust bin, sewage tank, etc.).

[0087] As shown, Figure 2As shown, the brush head 04 can further include a water outlet device 1. The water outlet device 1 can be used to provide cleaning water to the cleaning member 13 or the surface to be cleaned. The water outlet device 1 can deliver liquid to the cleaning member 13 to wet the cleaning member 13, which can improve the cleaning ability of the cleaning member 13, so as to improve the cleaning effect of the brush head 04. Alternatively, the water outlet device 1 can deliver liquid in front of the cleaning member 13 to wet the dirt on the surface to be cleaned in front of the cleaning member 13, so that the dirt on the surface to be cleaned can be easily cleaned by the cleaning member 13, which can also improve the cleaning effect of the brush head 04.

[0088] It should be noted that the front of the cleaning member 13 refers to the front of the cleaning member 13 in the movement direction of the brush head 04.

[0089] As Figure 2 shown, the brush head 04 can further include a water supply tank 3. The water supply tank 3 can be used to store liquid and can deliver liquid to downstream components. The water supply tank 3 can be in communication with the water outlet device 1 and provide cleaning water for the water outlet device 1. The water supply tank 3 can be in direct or indirect communication with the water outlet device 1.

[0090] Figure 3 and Figure 4 A schematic view showing the relative position relationship between the water outlet device 1 and the cleaning member 13 is shown. As Figure 3 and Figure 4 shown, the water outlet device 1 can include a water outlet member 11 and a steam output member 12.

[0091] As Figure 3 shown, the water outlet device 1 can include a water outlet member 11. The water outlet member 11 can provide unheated cleaning water to the cleaning member 13 or the surface to be cleaned. In some embodiments, the water outlet member 11 can provide heated cleaning water to the cleaning member 13 or the surface to be cleaned.

[0092] The water outlet member 11 can be a water strip. The extension direction of the water strip can be consistent with the extension direction of the cleaning member 13. The water strip can have a plurality of water outlet holes arranged at intervals. The plurality of water outlet holes are arranged at intervals along the extension direction of the water strip. The plurality of water outlet holes can deliver cleaning water to the cleaning member 13 or the surface to be cleaned. In this way, the water outlet range of the water outlet member 11 can be improved, and the wetting range of the cleaning member 13 or the dirt can be further improved, so as to further improve the cleaning effect of the brush head 04. However, the water outlet member 11 can not be a water strip, but can be other independent structural members capable of water outlet, or the water outlet member 11 can be a pipe end opening, and the present disclosure does not limit the water outlet member 11.

[0093] As Figure 4As shown, the water outlet device 1 can further include a steam output member 12. The steam output member 12 can provide steam to the cleaning member 13 or the surface to be cleaned. The steam output member 12 can deliver steam to the cleaning member 13 to wet the cleaning member 13, which can further improve the cleaning ability of the cleaning member 13, so as to further improve the cleaning effect of the brush head 04. Alternatively, the steam output member 12 can deliver steam to the front of the cleaning member 13 to heat and wet the dirt on the surface to be cleaned in front of the cleaning member 13, so that the dirt on the surface to be cleaned is more easily cleaned by the cleaning member 13, so as to also achieve the purpose of further improving the cleaning effect of the brush head 04. Alternatively, the steam output member 12 can also deliver steam to the cleaning member 13 to wet the cleaning member 13 to clean the cleaning member 13, improve the use convenience and service life of the brush head 04.

[0094] As shown, Figure 4 The steam output member 12 can include a steam outlet 121, which can deliver steam to the cleaning member 13 or the front of the cleaning member 13. The steam output member 12 can have a plurality of steam outlets 121 arranged at intervals, and steam can be delivered to the cleaning member 13 or the front of the cleaning member 13 through the plurality of steam outlets 121. In this way, the range of steam delivery by the steam output member 12 can be improved, so as to further improve the cleaning effect or self-cleaning effect of the brush head 04. However, the steam output member 12 can not include a steam outlet 121, and can be other independent structural members capable of delivering steam, or the steam output member 12 can be a pipe end opening, and the present disclosure does not limit the steam output member 12.

[0095] As shown, Figure 5 A modular schematic diagram showing the relative positional relationship of each component in the brush head 04 is shown. As shown, Figures 6 to 9 An actual schematic diagram showing the relative positional relationship of each component in the brush head 04 is shown.

[0096] As shown, Figures 5 to 9 The brush head 04 can further include a heater 4 and an electrical device 8. The heater 4 can be configured to heat a liquid. The heater 4 can be a boiler, but is not limited thereto, and the heater 4 can also be other components with heating capability. The electrical device 8 can be connected to the heater 4 for controlling the heater 4 or in communication with the heater 4.

[0097] The electric device 8 and the heater 4 can be located on two sides of the suction pipe 2 respectively, and the suction pipe 2 can separate the electric device 8 and the heater 4. In this way, a large distance can be provided between the electric device 8 and the heater 4, the temperature near the electric device 8 can be reduced, the influence of the high-temperature heat generated by the heater 4 on the electric device 8 can be reduced, and thus the normal work of the electric device 8 can be ensured, and the probability of damage of the electric device 8 can be reduced, so that the use reliability and service life of the brush head 04 can be improved. Moreover, in this way, the suction pipe 2 can be used as a spacer between the electric device 8 and the heater 4, and the suction pipe 2 can be used to block the heat generated by the heater 4, so that the temperature near the electric device 8 can be further reduced, the influence of the high-temperature heat generated by the heater 4 on the electric device 8 can be further reduced, and the use reliability and service life of the brush head 04 can be further improved.

[0098] Meanwhile, during the work of the brush head 04, there is high-speed flowing air in the suction pipe 2, and the high-speed flowing air can take away part of the high-temperature heat generated by the heater 4, so that the temperature near the electric device 8 can be further reduced, the influence of the high-temperature heat generated by the heater 4 on the electric device 8 can be further reduced, and the use reliability and service life of the brush head 04 can be further improved.

[0099] In some embodiments, the electric device 8 can include a liquid control assembly 81, which can be configured to control the delivery of liquid in the brush head 04. The liquid control assembly 81 can be in communication with the heater 4.

[0100] In some embodiments, the liquid control assembly 81 can include a first reversing valve 811. The first reversing valve 811 and the heater 4 can be located on two sides of the suction pipe 2 respectively, so as to avoid the influence of the high-temperature heat generated by the heater 4 on the normal work and service life of the first reversing valve 811.

[0101] The first input end of the first reversing valve 811 can be in communication with the water supply tank 3, the first output end of the first reversing valve 811 can be in communication with the input end of the heater 4, and the second output end of the first reversing valve 811 can be in communication with the water outlet device 1. The first reversing valve 811 can change the direction of the delivery of the cleaning water, so that the cleaning water can be delivered to the heater 4 or the water outlet device 1. When the first reversing valve 811 is in communication with the heater 4, the cleaning water can be heated by the heater 4 to output hot water. When the first reversing valve 811 is in communication with the water outlet device 1, the cleaning water can be directly output to the water outlet device 1. In some embodiments, the second output end of the first reversing valve 811 can be in communication with the water outlet element 11 in the water outlet device 1, so as to deliver the cleaning water to the water outlet element 11.

[0102] It should be noted that the pipeline through which the first output end of the first reversing valve 811 communicates with the input end of the heater 4 can cross the suction pipe 2. In this way, the high-speed air flowing in the suction pipe 2 can take away part of the heat in the pipeline, reducing the heat transferred by the heater 4 to the first reversing valve 811 through the pipeline.

[0103] As shown in Figures 5 to 9 , the hydraulic control assembly 81 can further include a second reversing valve 812. The second reversing valve 812 and the heater 4 can be located on the two sides of the suction pipe 2 respectively, so as to avoid the influence of the high-temperature heat generated by the heater 4 on the normal work and service life of the second reversing valve 812.

[0104] The input end of the second reversing valve 812 can communicate with the output end of the heater 4. The first output end of the second reversing valve 812 can communicate with the steam output 12. The second output end of the second reversing valve 812 can communicate with the water outlet 11. The second reversing valve 812 can change the direction of delivery, so that the liquid or water vapor output from the heater 4 can be delivered to the water outlet 11 or the steam output 12.

[0105] It should be noted that the pipeline through which the input end of the second reversing valve 812 communicates with the output end of the heater 4 crosses the suction pipe 2. In this way, the high-speed air flowing in the suction pipe 2 can take away part of the heat in the pipeline, reducing the heat transferred by the heater 4 to the second reversing valve 812 through the pipeline.

[0106] In some embodiments, the first reversing valve 811 is closer to the suction pipe 2 than the second reversing valve 812, so as to reduce the distance between the first reversing valve 811 and the components communicating with the first reversing valve 811 and located on the other side of the suction pipe 2, facilitating the pipeline arrangement inside the brush head 04.

[0107] In the present embodiment, as shown in Figure 6 and Figure 7 , the first reversing valve 811 and the second reversing valve 812 can be arranged side by side, and the arrangement direction of the first reversing valve 811 and the second reversing valve 812 can be at an acute angle or a right angle with the extension direction of the suction pipe 2. In this way, the pipeline arrangement inside the brush head 04 can be further facilitated, the space inside the brush head 04 can be saved, and the position interference between the communicating pipeline between the first reversing valve 811 and the components located on the other side of the suction pipe 2 and the second reversing valve 812 can be avoided, improving the rationality of the pipeline layout inside the brush head 04.

[0108] As shown in Figure 7As shown, the first reversing valve 811 can include a first communication part 8111 and a first valve body part 8112. The input end of the first reversing valve 811, the first output end of the first reversing valve 811, and the second output end of the first reversing valve 811 can all be located in the first communication part 8111. The projection of the first communication part 8111 in the first direction X can be located within the projection of the first valve body part 8112 in the first direction X, and the first direction X can be the direction in which the first communication part 8111 points to the first valve body part 8112. That is, it can be understood that the first communication part 8111 can be the small end of the first reversing valve 811, and the first valve body part 8112 can be the large end of the first reversing valve 811.

[0109] The second reversing valve 812 can include a second communication part 8121 and a second valve body part 8122. The input end of the second reversing valve 812, the first output end of the second reversing valve 812, and the second output end of the second reversing valve 812 can all be located in the second communication part 8121. The projection of the second communication part 8121 in the first direction X can be located within the projection of the second valve body part 8122 in the first direction X. That is, it can be understood that the second communication part 8121 can be the small end of the second reversing valve 812, and the second valve body part 8122 can be the large end of the second reversing valve 812.

[0110] The direction in which the first communication part 8111 points to the first valve body part 8112 can be opposite to the direction in which the second communication part 8121 points to the second valve body part 8122, that is, the setting directions of the first communication part 8111 and the second communication part 8121 are opposite. In this way, the space inside the brush head 04 can be further saved when the first reversing valve 811 and the second reversing valve 812 are arranged side by side. Moreover, in this way, the position interference between the pipeline in communication with the first communication part 8111 and the pipeline in communication with the second communication part 8121 can be avoided, further reducing the difficulty of arranging the pipelines inside the brush head 04.

[0111] In some embodiments, the first reversing valve 811 and the second reversing valve 812 can both be solenoid valves, so as to achieve the purpose of automatically controlling the cleaning water delivery work inside the brush head 04, and to liberate the labor of the operator. Moreover, in this way, the cleaning water delivery work inside the brush head 04 can be more accurately controlled, and the use performance of the brush head 04 can be improved. However, it is not limited thereto, and those skilled in the art should understand that the first reversing valve 811 and the second reversing valve 812 can also be other types of valve bodies, which are also within the protection scope of the present disclosure.

[0112] In some embodiments, as shown in FIG. 6, the first reversing valve 811 and the second reversing valve 812 can be arranged side by side. Figures 5 to 8As shown, the brush head 04 can further include a third multi-way 15. The second output end of the first reversing valve 811, the second output end of the second reversing valve 812, and the water outlet 11 can be in communication with different ports of the third multi-way 15, respectively. By arranging the third multi-way 15, the two relatively long pipelines between the second output end of the first reversing valve 811 and the water outlet 11 and between the second output end of the second reversing valve 812 and the water outlet 11 can be integrated into three relatively short pipelines, i.e., one pipeline between the second output end of the first reversing valve 811 and the third multi-way 15, one pipeline between the second output end of the second reversing valve 812 and the third multi-way 15, and one pipeline between the water outlet 11 and the third multi-way 15, so as to reduce the difficulty of pipeline arrangement and save the space inside the brush head 04. In the embodiment, the third multi-way 15 can be a three-way, i.e., the third multi-way 15 can have three ports, but is not limited thereto, and the third multi-way 15 can also have multiple ports.

[0113] The third multi-way 15, the first reversing valve 811, and the second reversing valve 812 can be located on the same side of the suction pipe 2. In this way, the distance between the third multi-way 15 and the first reversing valve 811 and the second reversing valve 812 can be reduced, and the communication between the third multi-way 15 and the first reversing valve 811 and the second reversing valve 812 can be facilitated.

[0114] As shown, Figures 5 to 9 The brush head 04 can further include a second liquid pump 7. The input end of the second liquid pump 7 can be in communication with the water supply tank 3, so as to suck the cleaning water stored in the water supply tank 3. The output end of the second liquid pump 7 can be in communication with the input end of the heater 4, so as to supply the cleaning water to the heater 4.

[0115] In some embodiments, the second liquid pump 7 and the heater 4 can be located on the same side of the suction pipe 2. In this way, the distance between the second liquid pump 7 and the heater 4 can be reduced, and the length of the communication pipeline between the output end of the second liquid pump 7 and the heater 4 can be reduced. In this way, when the heater 4 is working, the cleaning water output from the output end of the second liquid pump 7 can reach the heater 4 as soon as possible, so as to avoid dry burning of the heater 4, thereby reducing the probability of damage of the heater 4 and improving the use reliability and service life of the brush head 04.

[0116] As shown, Figures 5 to 9 The brush head 04 can further include a first liquid pump 6. The input end of the first liquid pump 6 can be in communication with the water supply tank 3, so as to suck the liquid stored in the water supply tank 3. The output end of the first liquid pump 6 can be in communication with the input end of the first reversing valve 811, so as to deliver the cleaning water to the first reversing valve 811.

[0117] In some embodiments, the flow rate of the second liquid pump 7 can be less than that of the first liquid pump 6. The pipeline between the first liquid pump 6 and the heater 4 can have a first length, and the pipeline between the second liquid pump 7 and the heater 4 can have a second length, which can be less than the first length. Since the second liquid pump 7 has a smaller water supply flow rate, the above arrangement can prevent the first liquid pump 6 from taking too much cleaning water due to its large flow rate, ensure that the second liquid pump 7 can obtain sufficient cleaning water, and timely deliver sufficient cleaning water to the heater 4, thereby avoiding the problem of dry burning of the heater 4.

[0118] As shown in Figures 5 to 9 , the second liquid pump 7 and the first liquid pump 6 can be located on the same side of the sewage suction pipe 2. In this way, the first liquid pump 6 and the first reversing valve 811 can be located on both sides of the sewage suction pipe 2, and the first reversing valve 811 and the heater 4 can be located on both sides of the sewage suction pipe 2. In this way, the length of the pipeline between the first liquid pump 6 and the heater 4 can be increased, further preventing the first liquid pump 6 from taking too much cleaning water due to its large flow rate, and further ensuring the amount of cleaning water that the second liquid pump 7 can obtain.

[0119] Further, the second liquid pump 7 can be located between the heater 4 and the first liquid pump 6. In this way, the distance between the second liquid pump 7 and the heater 4 can be closer, thereby further reducing the length of the pipeline between the second liquid pump 7 and the heater 4, and further ensuring that when the heater 4 starts to work, the second liquid pump 7 can timely deliver cleaning water to the heater 4, thereby further avoiding dry burning of the heater 4, reducing the probability of damage to the heater 4, and improving the use reliability and service life of the brush head 04.

[0120] The flow rate of the first liquid pump 6 can range from 10 ml / min to 500 ml / min, for example, 10 ml / min, 50 ml / min, 100 ml / min, 150 ml / min, 200 ml / min, 250 ml / min, 300 ml / min, 350 ml / min, 400 ml / min, 450 ml / min, 500 ml / min, etc. In this way, the delivery amount of the first liquid pump 6 can be ensured.

[0121] The flow rate of the second liquid pump 7 can range from 0.5 ml / min to 9 ml / min, for example: 0.5 ml / min, 1 ml / min, 2 ml / min, 3 ml / min, 4 ml / min, 5 ml / min, 6 ml / min, 7 ml / min, 8 ml / min, 9 ml / min, etc. This setting can avoid the problem of the heater 4 burning dry due to insufficient cleaning water delivered by the second liquid pump 7, thus preventing damage to the heater 4. At the same time, it can also avoid the problem of insufficient water vapor formation due to insufficient cleaning water delivered by the second liquid pump 7, thus ensuring the cleaning effect of the brush head 04.

[0122] In some embodiments, such as Figures 5 to 9 As shown, the brush head 04 may further include a first multi-port 9. The first multi-port 9 may have multiple ports. The input terminals of the water supply tank 3, the first liquid pump 6, and the second liquid pump 7 may be connected to different ports of the first multi-port 9, so as to divert the cleaning water in the water supply tank 3 to the input terminals of the first liquid pump 6 and / or the second liquid pump 7 through the first multi-port 9. In this embodiment, the first multi-port 9 may be a three-way valve, that is, the first multi-port 9 may have three ports, but it is not limited to this, and the first multi-port 9 may have more than three ports.

[0123] In one embodiment, the first multi-port 9 and the second liquid pump 7 can be located on the same side of the suction pipe 2, thereby reducing the distance between the first multi-port 9 and the second liquid pump 7 and facilitating communication between the first multi-port 9 and the second liquid pump 7.

[0124] There can be a first flow resistance between the first multi-port 9 and the first liquid pump 6, and a second flow resistance between the first multi-port 9 and the second liquid pump 7. The first flow resistance can be greater than the second flow resistance, so as to avoid excessive delivery of clean water output from the water supply tank 3 to the first liquid pump 6, and ensure that the second liquid pump 7 can also obtain sufficient clean water.

[0125] The pipeline between the first multi-port 9 and the first liquid pump 6 can have a third length, and the pipeline between the second multi-port 10 and the second liquid pump 7 can have a fourth length, which can be less than the third length. This can increase the first flow resistance between the first multi-port 9 and the first liquid pump 6, making the first flow resistance greater than the second flow resistance.

[0126] The pipeline between the first multi-port 9 and the first liquid pump 6 can have a first cross-sectional area, and the pipeline between the first multi-port 9 and the second liquid pump 7 can have a second cross-sectional area. The second cross-sectional area can be larger than the first cross-sectional area, thereby reducing the second flow resistance between the first multi-port 9 and the second liquid pump 7, so that the first flow resistance is greater than the second flow resistance.

[0127] The first number of components can be arranged on the pipeline between the first multi-way 9 and the first liquid pump 6. The second number of components can be arranged on the pipeline between the first multi-way 9 and the second liquid pump 7. The second number of components can be less than the first number of components, so that the cleaning water output from the water supply tank 3 passes through more components from the first multi-way 9 to the first liquid pump 6, so as to increase the first flow resistance, so that the first flow resistance is greater than the second flow resistance.

[0128] It should be noted that the components described herein can be: multi-way, valve body, liquid pump, and other components with water flow capacity.

[0129] In an embodiment, the input end of the second liquid pump 7 can be directly communicated with the first multi-way 9, i.e., the number of components arranged on the pipeline between the second liquid pump 7 and the first multi-way 9 is 0, so as to ensure that the first multi-way 9 and the second liquid pump 7 have a smaller flow resistance.

[0130] The input end of the first liquid pump 6 is communicated with the first multi-way 9 through the components arranged on the pipeline between the first multi-way 9 and the first liquid pump 6. In this way, the first multi-way 9 and the first liquid pump 6 can have a larger flow resistance.

[0131] As shown in Figures 5 to 9 The brush head 04 can further include a second multi-way 10. The second multi-way 10 can be arranged on the pipeline between the first multi-way 9 and the first liquid pump 6. The second multi-way 10 can have a plurality of ports, and the input end of the first liquid pump 6 can be communicated with the second multi-way 10. It can be understood that the second multi-way 10 can be one of the components arranged on the pipeline between the first multi-way 9 and the first liquid pump 6.

[0132] In an embodiment, the second multi-way 10 and the first liquid pump 6 can be located on the same side of the brush head 04, for example, the second multi-way 10 and the first liquid pump 6 can be located on the same side of the suction pipe 2, so as to reduce the distance between the second multi-way 10 and the first liquid pump 6, and facilitate the communication between the second multi-way 10 and the first liquid pump 6.

[0133] In some embodiments, as shown in Figures 5 to 9 The brush head 04 can further include a pressure relief valve 16. The pressure relief valve 16 and the heater 4 can be located on the same side of the suction pipe 2. The first input end of the pressure relief valve 16 can be communicated with the first output end of the first reversing valve 811. The second input end of the pressure relief valve 16 can be communicated with the output end of the second liquid pump 7. The output end of the pressure relief valve 16 can be communicated with the input end of the heater 4. The pressure relief end of the pressure relief valve 16 can be communicated with the outside of the brush head 04, so as to adjust the pressure in the pipeline, and avoid damaging the components on the pipeline due to excessive pressure in the pipeline.

[0134] The pressure relief valve 16 may include a spring valve. When the internal pressure of the pipeline is too high, the spring valve will automatically open, and when the internal pressure of the pipeline is normal, the valve will automatically close. This allows for automatic regulation of the internal pressure of the pipeline.

[0135] like Figures 5 to 9 As shown, the brush head 04 may further include a fourth multi-port 17. The fourth multi-port 17 may have multiple ports, and the output end of the second liquid pump 7, the first output end of the first reversing valve 811, and the input end of the heater 4 may be connected to different ports of the fourth multi-port 17 respectively. By setting the fourth multi-port 17, the pipeline between the output end of the second liquid pump 7 and the heater 4 and the pipeline between the first output end of the first reversing valve 811 and the heater 4 can be integrated, dividing two longer pipelines into three shorter pipelines: one between the output end of the second liquid pump 7 and the fourth multi-port 17, one between the first output end of the first reversing valve 811 and the fourth multi-port 17, and one between the heater 4 and the fourth multi-port 17. This reduces the difficulty of pipeline arrangement and saves internal space in the brush head 04. In this embodiment, the fourth multi-port 17 can be a three-way valve, that is, the fourth multi-port 17 may have three ports, but it is not limited to this; the third multi-port 15 may also have multiple ports.

[0136] In some embodiments, the fourth multi-port 17 and the heater 4 can be located on the same side of the suction pipe 2. This arrangement can reduce the length of the pipe connecting the fourth multi-port 17 and the heater 4, allowing the liquid to reach the heater 4 as quickly as possible, and further avoiding the risk of the heater 4 burning dry.

[0137] In some embodiments, the fourth multi-port 17 can be reused as a pressure relief valve 16, that is, the valve body can integrate the functions of the fourth multi-port 17 and the pressure relief valve 16. This configuration saves on manufacturing molds and reduces the manufacturing cost of the brush head 04. Furthermore, it reduces the number of components within the brush head 04, saving internal space.

[0138] In some embodiments, such as Figures 5 to 9 As shown, the water supply tank 3 can be equipped with a water supply connector 31. The input end of the first liquid pump 6, the input end of the second liquid pump 7, and the first multi-port 9 can all be connected to the water supply connector 31 to connect to the water supply tank 3.

[0139] The water supply connector 31 and the first liquid pump 6 can be located on opposite sides of the suction pipe 2. This arrangement increases the length of the pipe between the water supply connector 31 and the first liquid pump 6, allowing the pipe to span both sides of the suction pipe 2. This allows the cleaning water flowing from the water supply connector 31 to the first liquid pump 6 to absorb heat between the heater 4 and the electrical components 8, further reducing the temperature near the electrical components 8.

[0140] The water supply joint 31 can be close to the sewage pipe 2 relative to the first reversing valve 811. In this way, position interference between the pipeline connected with the water supply joint 31 and the pipeline connected with the first reversing valve 811 can be avoided, and the layout rationality of the internal pipeline of the brush head 04 can be optimized.

[0141] In some embodiments, as shown in Figures 5 to 9 The brush head 04 can further include a cleaning liquid supply bin 20 and a third liquid pump 14. The cleaning liquid supply bin 20 can be used to store cleaning liquid, and the cleaning liquid supply bin 20 can be provided with a cleaning liquid supply joint 201. The input end of the third liquid pump 14 can be in communication with the cleaning liquid supply joint 201 to communicate with the cleaning liquid supply bin 20 through the cleaning liquid supply joint 201. The output end of the third liquid pump 14 can be in communication with the second multi-way joint 10, and the third liquid pump 14 can draw out the cleaning liquid in the cleaning liquid supply bin 20 through the cleaning liquid supply joint 20 and deliver it to the second multi-way joint 10.

[0142] In this embodiment, the second multi-way joint 10 can be a three-way joint, i.e., the second multi-way joint 10 can have three ports, but is not limited to this, and the second multi-way joint 10 can have more than four ports. Moreover, by arranging the second multi-way joint 10 between the first multi-way joint 9 and the first liquid pump 6, the second multi-way joint 10 can be located downstream of the first multi-way joint 9, and the cleaning liquid output by the third liquid pump 14 can enter the first liquid pump 6 after passing through the second multi-way joint 10, rather than entering the second liquid pump 7 through the first multi-way joint 9. In this way, the situation that the cleaning liquid enters the heater 4 through the second liquid pump 7 and causes the brush head 04 to fail to work normally can be avoided, thereby improving the use reliability of the brush head 04 and improving the user experience.

[0143] In other embodiments, the brush head 04 can not be provided with the second multi-way joint 10, and only one first multi-way joint 9 can be arranged in the brush head 04, and the output end of the third liquid pump 14 can be in communication with the first multi-way joint 9, thereby reducing the manufacturing cost of the brush head 04 and saving the internal space of the brush head 04. In this embodiment, the first multi-way joint 9 can be a four-way joint, i.e., the first multi-way joint 9 can have four ports, but is not limited to this, and the first multi-way joint 9 can have more than four ports.

[0144] In some embodiments, as shown in Figures 5 to 9As shown, the cleaning liquid supply joint 201 and the third liquid pump 14 can be located on the same side of the suction pipe 2 as the first switching valve 811 and the second switching valve 812. In this way, the distance between the first switching valve 811 and the second switching valve 812 and the cleaning liquid supply joint 201 and the third liquid pump 14 can be short, and the heat around the first switching valve 811 and the second switching valve 812 can be further reduced by the cleaning liquid in the pipeline after the cleaning liquid enters the pipeline through the cleaning liquid supply joint 201, thereby further reducing the probability of failure or damage of the first switching valve 811 and the second switching valve 812.

[0145] In addition, when the third liquid pump 14 is located on the same side of the suction pipe 2 as the first switching valve 811 and the second switching valve 812, the third liquid pump 14 is located on the two sides of the suction pipe 2 as the first multi-way 9 and the second multi-way 10, so that the pipeline length between the third liquid pump 14 and the first multi-way 9 or the second multi-way 10 can be increased, so that the pipeline between the third liquid pump 14 and the first multi-way 9 or the second multi-way 10 spans the suction pipe 2, thereby increasing the cooling range of the cleaning liquid in the pipeline.

[0146] At the same time, since there are fewer components on the side of the first switching valve 811 and the second switching valve 812, the cleaning liquid supply joint 201 and the third liquid pump 14 are arranged on the same side of the first switching valve 811 and the second switching valve 812, which can optimize the internal space layout of the brush head 04 and prevent the problem of positional interference between adjacent components due to the crowded arrangement between components.

[0147] In other embodiments, the cleaning liquid supply joint 201 and the third liquid pump 14 can be located on the same side of the suction pipe 2 as the first multi-way 9 and the second multi-way 10. In this way, the distance between the third liquid pump 14 and the first multi-way 9 or the second multi-way 10 can be reduced, thereby reducing the pipeline length between the third liquid pump 14 and the first multi-way 9 or the second multi-way 10, and saving the manufacturing cost of the brush head 04.

[0148] In some embodiments, the cleaning liquid supply tank 20 can be located in the water supply tank 3 to improve the integration of the brush head 04. The cleaning liquid addition port of the cleaning liquid supply tank 20 and the liquid addition port of the water supply tank 3 can be different addition ports to facilitate the addition of cleaning liquid and liquid in the water supply tank 3, respectively.

[0149] In some embodiments, as Figures 5 to 9As shown, the heater 4 can include a heater 4 body and a first filter screen. The first filter screen can be arranged in the heater 4 body and located between the input end and the output end of the heater 4 to filter the liquid in the heater 4 to avoid impurities blocking the pipeline and the water outlet device 1, thereby improving the service life of the brush head 04. The mesh aperture of the first filter screen can be 1mm to 3mm, for example, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. In this way, the first filter screen can have good filtering effect while improving the flow capacity of the first filter screen to ensure that the water in the heater 4 can pass through the first filter screen normally and reduce the probability of the first filter screen being blocked.

[0150] In one embodiment, as shown in FIG. 4, the brush head 04 can further include a second filter screen 5, which can be arranged at the output end of the heater 4 or downstream of the heater 4. The mesh aperture of the second filter screen 5 can be smaller than that of the first filter screen. In this way, the second filter screen 5 can further filter the cleaning water or water vapor output from the heater 4 to further remove impurities inside, further reduce the probability of impurities blocking the downstream pipeline and the water outlet device 1, and further improve the service life of the brush head 04. Figures 5 to 9

[0151] The aperture of the second filter screen 5 can be 0.2mm to 1mm, for example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. In this way, the second filter screen 5 can have good filtering effect and improve the flow capacity of the second filter screen 5 to ensure that the cleaning water or water vapor in the heater 4 can pass through the second filter screen 5 normally.

[0152] The filtering area of the second filter screen 5 can be greater than that of the first filter screen to improve the filtering effect of the second filter screen 5 and ensure that the liquid or water vapor delivered to the downstream pipeline and the water outlet device 1 is impurity-free. Moreover, by increasing the filtering area of the second filter screen 5, the probability of the second filter screen 5 being blocked can be reduced.

[0153] The filtering area of the second filter screen 5 can be 500mm 2 to 2000mm 2 , for example, 500mm 2 , 600mm 2 , 700mm 2 , 800mm 2 , 900mm 2 , 1000mm 2 , 1100mm 2 , 1200mm 2 , 1300mm 2 , 1400mm​2 1500mm 2 1600mm 2 1700mm 2 1800mm 2 1900mm 2 2000mm 2 etc. In this way, the second filter screen 5 can have sufficient filtering area, and can also avoid the problem of occupying a large internal space of the brush head 04 due to the large surface area of the second filter screen 5, thereby facilitating the miniaturization of the brush head 04.

[0154] In one embodiment, as shown in Figures 5 to 8 , the brush head 04 can further include a flow detector 18. The flow detector 18 can be a flow sensor or the like. The flow detector 18 can be located between the water supply joint 31 and the first multi-way 9, for detecting the amount of liquid output from the water supply tank 3. Moreover, by detecting whether there is water in the pipeline between the water supply joint 31 and the first multi-way 9, it can be determined whether to turn on the heater 4, so as to prevent the heater 4 from being dry-burned without water, thereby reducing the probability of damage to the heater 4.

[0155] In one embodiment, a preset time can be set, and the heater 4 can be turned on only when the flow detector 18 detects water in the pipeline between the water supply joint 31 and the first multi-way 9 within the preset time. The preset time can be seconds, but is not limited thereto.

[0156] In one embodiment of the present disclosure, as shown in Figures 5 to 9 , the electrical device 8 can further include a controller 82. The controller 82 can be used to control the operation of various components in the brush head 04, for example, can be used to control the opening or closing of the first reversing valve 811, the second reversing valve 812, the first liquid pump 6, the second liquid pump 7, and the third liquid pump 14. The controller 82 can be a PCB circuit board, but is not limited thereto. The controller 82 can be away from the cleaning element 13 relative to the heater 4, so as to further increase the distance between the controller 82 and the heater 4, further reduce the temperature near the controller 82, and further reduce the influence of the high-temperature heat generated by the heater 4 on the controller 82, thereby ensuring the normal operation of the controller 82, reducing the probability of damage to the controller 82, and further improving the use reliability and service life of the brush head 04.

[0157] As shown in Figure 5 and Figure 6As shown, the brush head 04 can further include a housing 19. The housing 19 can have a receiving cavity 191, and the controller 82 and the heater 4 can be located in the receiving cavity 191. The controller 82 can be located at a side of the receiving cavity 191 away from the cleaning member 13, and the heater 4 can be located at a side of the receiving cavity 191 close to the cleaning member 13. In this way, the distance between the controller 82 and the heater 4 can be further increased, and the influence of the high-temperature heat generated by the heater 4 on the controller 82 can be further reduced, so that the normal work of the controller 82 can be further ensured, the probability of damage of the controller 82 can be reduced, and the use reliability and service life of the brush head 04 can be improved.

[0158] In an embodiment, the remaining components and pipelines in the brush head 04 can also be located in the receiving cavity 191, so that the integration of the brush head 04 can be improved, and the components in the brush head 04 can be protected by the housing 19, so that the probability of damage of the components in the brush head 04 due to external force can be reduced, and the use reliability and service life of the brush head 04 can be improved.

[0159] In an embodiment of the present disclosure, as shown in Figures 5 to 9 The brush head 04 can have multiple cleaning modes. For example, the brush head 04 can have a cold water cleaning mode, a steam cleaning mode, a hot water cleaning mode, a strong cleaning mode, a scale removal cleaning mode, and a self-cleaning mode.

[0160] In the cold water cleaning mode, the first liquid pump 6 can be opened, the second liquid pump 7 and the heater 4 can be closed, and the first reversing valve 811 can be connected to the output end of the first liquid pump 6 and the water outlet 11, so that the cleaning water in the water supply tank 3 can be delivered to the water outlet 11 through the first liquid pump 6.

[0161] In the steam cleaning mode, the first liquid pump 6, the second liquid pump 7, and the heater 4 can be opened, the first reversing valve 811 can be connected to the output end of the first liquid pump 6 and the water outlet 11, and the second reversing valve 812 can be connected to the output end of the heater 4 and the steam output 12, so that part of the cleaning water in the water supply tank 3 can be directly delivered to the water outlet 11 through the first liquid pump 6. Another part of the cleaning water can be delivered to the heater 4 through the second liquid pump 7, heated in the heater 4 to form water vapor, and delivered to the steam output 12.

[0162] In the hot water cleaning mode, the first liquid pump 6 and the heater 4 can be opened, the second liquid pump 7 can be closed, the first reversing valve 811 can be connected to the input end of the heater 4, and the second reversing valve 812 can be connected to the water outlet 11, so that the cleaning water extracted by the first liquid pump 6 can be delivered to the heater 4 for heating, and the heated cleaning water can be delivered to the water outlet 11 through the second reversing valve 812.
