[0071] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0072] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0073] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0074] In this disclosure, "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 one of A, B, and C, or any combination of A, B, and C, or other possible content / elements. The arbitrary combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0075] As shown in Figure 1, this 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 floor scrubber, a robotic vacuum cleaner, a vacuum and mop combo, etc., and this disclosure does not impose specific limitations on it.

[0076] The cleaning device 01 can interface 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. Alternatively, the base station 02 can clean the floor-cleaning components of the cleaning device 01. In some embodiments, the base station 02 can also suck up dirt stored in the cleaning device 01. This disclosure does not limit the specific form of the base station 02.

[0077] Taking cleaning equipment 01 as an example of a passive cleaning device, such as a floor scrubber, as shown in Figure 1, cleaning equipment 01 may include a handheld unit 03 and a brush head 04. The handheld unit 03 can be connected to the brush head 04. The brush head 04 can be used to clean the surface to be cleaned. The operator can move and / or operate the cleaning equipment 01 by holding the handheld unit 03 to clean the surface using the brush head 04.

[0078] It should be noted that the cleaning equipment 01 described above, which is a floor scrubber, is only one embodiment. Those skilled in the art should understand that other forms of the cleaning equipment 01 are also within the scope of protection of this disclosure.

[0079] As shown in Figure 2, the brush head 04 may include a cleaning component 13 and a suction tube 2. The cleaning component 13 can be used to clean the surface to be cleaned.

[0080] The cleaning component 13 can contact the surface to be cleaned for cleaning the surface. The cleaning component 13 can be a roller brush, but is not limited to this. The cleaning component 13 can also be a brush strip, side brush, etc., and can be selected and set according to the actual situation, all of which are within the protection scope of this disclosure.

[0081] The suction pipe 2 can be configured to suck up dirt from the surface to be cleaned. That is, it can be understood that the suction pipe 2 can suck up dirt from the surface to be cleaned or from the surface of the cleaning component 13 by means of high-speed airflow.

[0082] In one embodiment, the opening of the suction pipe 2 can be positioned directly opposite the cleaning component 13 to facilitate the suction of dirt from the surface of the cleaning component 13. Furthermore, the opening of the suction pipe 2 can be positioned directly opposite the central region of the cleaning component 13 so that the suction pipe 2 has the same suction capacity for dirt located at both ends of the cleaning component 13, thereby improving the suction effect of the suction pipe 2 on the surface of the cleaning component 13.

[0083] In some embodiments, for better cleaning results, the opening of the suction pipe 2 can be located in the middle of the brush head 04, or near the middle of the brush head 04. The suction pipe 2 can extend from the opening of the suction pipe 2 to the dirt collection part (dust bin, wastewater bin, etc.).

[0084] As shown in Figure 2, the brush head 04 may also include a water outlet device 1. The water outlet device 1 can be used to provide cleaning water to the cleaning component 13 or the surface to be cleaned. The water outlet device 1 can deliver liquid to the cleaning component 13 to wet it, thereby improving the cleaning ability of the cleaning component 13 and thus enhancing the cleaning effect of the brush head 04. Alternatively, the water outlet device 1 can be directed in front of the liquid delivery to the cleaning component 13 to wet the dirt on the surface to be cleaned in front of the cleaning component 13, making it easier for the cleaning component 13 to remove the dirt, thus also achieving the same purpose of improving the cleaning effect of the brush head 04.

[0085] It should be noted that the "front" of the cleaning component 13 mentioned above refers to the front of the cleaning component 13 in the direction of movement of the brush head 04.

[0086] As shown in Figure 2, the brush head 04 may also include a water supply tank 3. The water supply tank 3 can be used to store liquid and can supply liquid to downstream components. The water supply tank 3 can be connected to the water outlet device 1 and provide cleaning water to the water outlet device 1. The water supply tank 3 can be directly or indirectly connected to the water outlet device 1.

[0087] Figures 3 and 4 show schematic diagrams illustrating the relative positional relationship between the water outlet device 1 and the cleaning component 13. As shown in Figures 3 and 4, the water outlet device 1 may include a water outlet component 11 and a steam output component 12.

[0088] As shown in Figure 3, the water outlet device 1 may include a water outlet component 11. The water outlet component 11 can provide unheated cleaning water to the cleaning component 13 or the surface to be cleaned. In some embodiments, the water outlet component 11 can provide heated cleaning water to the cleaning component 13 or the surface to be cleaned.

[0089] The water outlet component 11 can be a water strip. The extension direction of the water strip can be consistent with the extension direction of the cleaning component 13. The water strip can have multiple water outlet holes spaced apart. The multiple water outlet holes are spaced apart along the extension direction of the water strip. The multiple water outlet holes can deliver cleaning water to the cleaning component 13 or the surface to be cleaned. This configuration can increase the water outlet range of the water outlet component 11, further increase the wetting range of the cleaning component 13 or the dirt, thereby further improving the cleaning effect of the brush head 04. However, it is not limited to this. The water outlet component 11 may not be a water strip. It may be other independent structural components capable of dispensing water, or the water outlet component 11 may be an opening at the end of a pipe, etc. This disclosure does not limit this.

[0090] As shown in Figure 4, the water outlet device 1 may also include a steam output component 12. The steam output component 12 can supply steam to the cleaning component 13 or the surface to be cleaned. The steam output component 12 can deliver steam to the cleaning component 13 to moisten it, thereby further improving the cleaning ability of the cleaning component 13 and thus enhancing the cleaning effect of the brush head 04. Alternatively, the steam output component 12 can deliver steam to the front of the cleaning component 13 to heat and moisten the dirt on the surface to be cleaned in front of the cleaning component 13, making it easier for the cleaning component 13 to clean the dirt, thus also further enhancing the cleaning effect of the brush head 04. Alternatively, the steam output component 12 can also deliver steam to the cleaning component 13 to moisten it, enabling self-cleaning of the cleaning component 13 and improving the ease of use and lifespan of the brush head 04.

[0091] As shown in Figure 4, the steam output component 12 may include steam nozzles 121, which can deliver steam to the cleaning component 13 or the front of the cleaning component 13. The steam output component 12 may have multiple spaced-apart steam nozzles 121, through which steam can be delivered to the cleaning component 13 or the front of the cleaning component 13. This configuration can increase the range of steam delivery by the steam output component 12, thereby further improving the cleaning effect or self-cleaning effect of the brush head 04. However, it is not limited to this; the steam output component 12 may not include steam nozzles 121, and it may be other independent structural components capable of delivering steam, or the steam output component 12 may be the end opening of a pipeline, etc. This disclosure does not limit this.

[0092] Figure 5 shows a modular schematic diagram illustrating the relative positions of the components in brush head 04. Figures 6 to 9 show actual schematic diagrams illustrating the relative positions of the components in brush head 04.

[0093] As shown in Figures 5 to 9, the brush head 04 may further include a heater 4 and an electrical component 8. The heater 4 may be configured to heat a liquid. The heater 4 can be a boiler, but is not limited to this; it can also be other components with heating capabilities. The electrical component 8 may be connected to the heater 4 for controlling the heater 4 or for communicating with the heater 4.

[0094] Electrical component 8 and heater 4 can be located on opposite sides of suction pipe 2, with suction pipe 2 separating them. This arrangement creates a larger distance between electrical component 8 and heater 4, reducing the temperature near electrical component 8 and minimizing the impact of the high-temperature heat generated by heater 4 on electrical component 8. This ensures the normal operation of electrical component 8 and reduces the probability of damage, thereby improving the reliability and lifespan of brush head 04. Furthermore, this arrangement utilizes suction pipe 2 as a spacer between electrical component 8 and heater 4, blocking the heat generated by heater 4, further reducing the temperature near electrical component 8 and minimizing the impact of the high-temperature heat generated by heater 4 on electrical component 8, further improving the reliability and lifespan of brush head 04.

[0095] Meanwhile, during the operation of the brush head 04, there is high-speed airflow inside the suction pipe 2. This high-speed airflow can carry away some of the high-temperature heat generated by the heater 4, which can further reduce the temperature near the electrical components 8, further reduce the impact of the high-temperature heat generated by the heater 4 on the electrical components 8, and further improve the reliability and service life of the brush head 04.

[0096] In some embodiments, the electrical device 8 may include a liquid control assembly 81, which may be configured to control the delivery of liquid within the brush head 04. The liquid control assembly 81 may be in communication with the heater 4.

[0097] In some embodiments, the hydraulic control assembly 81 may include a first directional valve 811. The first directional valve 811 and the heater 4 may be located on opposite sides of the suction pipe 2 to avoid the high-temperature heat generated by the heater 4 affecting the normal operation and service life of the first directional valve 811.

[0098] The first input terminal of the first reversing valve 811 can be connected to the water supply tank 3, the first output terminal of the first reversing valve 811 can be connected to the input terminal of the heater 4, and the second output terminal of the first reversing valve 811 can be connected to the water outlet device 1. The first reversing valve 811 can change the direction of the clean water delivery, allowing the clean water to be delivered to the heater 4 or to the water outlet device 1. When the first reversing valve 811 is connected to the heater 4, the clean water can be heated by the heater 4 to output hot water. When the first reversing valve 811 is connected to the water outlet device 1, the clean water can be directly output to the water outlet device 1. In some embodiments, the second output terminal of the first reversing valve 811 can be connected to the water outlet component 11 in the water outlet device 1 to deliver the clean water to the water outlet component 11.

[0099] It should be noted that the pipe connecting the first output end of the first reversing valve 811 to the input end of the heater 4 can cross the suction pipe 2. This arrangement allows the high-speed airflow in the suction pipe 2 to carry away some of the heat in the pipe, reducing the heat transferred from the heater 4 to the first reversing valve 811 through the pipe.

[0100] As shown in Figures 5 to 9, the hydraulic control assembly 81 may further include a second directional valve 812. The second directional valve 812 and the heater 4 may be located on opposite sides of the suction pipe 2 to avoid the high-temperature heat generated by the heater 4 affecting the normal operation and service life of the second directional valve 812.

[0101] The input end of the second reversing valve 812 can be connected to the output end of the heater 4. The first output end of the second reversing valve 812 can be connected to the steam output component 12. The second output end of the second reversing valve 812 can be connected to the water outlet component 11. The second reversing valve 812 can change the direction of delivery, so that the liquid or steam output from the heater 4 can be delivered to the water outlet component 11 or to the steam output component 12.

[0102] It should be noted that the pipe connecting the input end of the second reversing valve 812 to the output end of the heater 4 crosses the suction pipe 2. This arrangement allows the high-speed airflow in the suction pipe 2 to carry away some of the heat in the pipe, reducing the heat transferred from the heater 4 to the second reversing valve 812 through the pipe.

[0103] In some embodiments, the first reversing valve 811 is located closer to the suction pipe 2 than the second reversing valve 812 to reduce the distance between the first reversing valve 811 and the component connected thereto and located on the other side of the suction pipe 2, so as to facilitate the arrangement of the tubing within the brush head 04.

[0104] In this embodiment, as shown in Figures 6 and 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 form an acute angle or a right angle with the extension direction of the suction pipe 2. This arrangement can further facilitate the arrangement of pipelines inside the brush head 04, save internal space of the brush head 04, and avoid positional interference between the connecting pipeline between the first reversing valve 811 and the component located on the other side of the suction pipe 2 and the second reversing valve 812, thereby improving the rationality of the pipeline layout inside the brush head 04.

[0105] As shown in Figure 7, the first directional control valve 811 may include a first connecting portion 8111 and a first valve body portion 8112. The input end, first output end, and second output end of the first directional control valve 811 may all be located within the first connecting portion 8111. The projection of the first connecting portion 8111 onto the first direction X may lie within the projection of the first valve body portion 8112 onto the first direction X, where the first direction X can be the direction from the first connecting portion 8111 to the first valve body portion 8112. That is, it can be understood that the first connecting portion 8111 can be the small end of the first directional control valve 811, and the first valve body portion 8112 can be the large end of the first directional control valve 811.

[0106] The second directional control valve 812 may include a second connecting portion 8121 and a second valve body portion 8122. The input end, the first output end, and the second output end of the second directional control valve 812 may all be located within the second connecting portion 8121. The projection of the second connecting portion 8121 in the first direction X may be located within the projection of the second valve body portion 8122 in the first direction X. That is, it can be understood that the second connecting portion 8121 can be the small end of the second directional control valve 812, and the second valve body portion 8122 can be the large end of the second directional control valve 812.

[0107] The direction in which the first connecting part 8111 points to the first valve body part 8112 can be opposite to the direction in which the second connecting part 8121 points to the second valve body part 8122; that is, the setting directions of the first connecting part 8111 and the second connecting part 8121 are opposite. This arrangement further saves internal space in the brush head 04 when the first reversing valve 811 and the second reversing valve 812 are arranged side-by-side. Furthermore, this arrangement avoids positional interference between the pipes connected to the first connecting part 8111 and the pipes connected to the second connecting part 8121, further reducing the difficulty of arranging pipes inside the brush head 04.

[0108] In some embodiments, both the first reversing valve 811 and the second reversing valve 812 can be solenoid valves to automate the delivery of cleaning water within the brush head 04, thereby freeing up the operator's labor. Furthermore, this configuration allows for more precise control of the delivery of cleaning water within the brush head 04, improving its performance. However, this is not a limitation; 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 scope of this disclosure.

[0109] In some embodiments, as shown in Figures 5 to 8, the brush head 04 may further include a third multi-port 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 may be connected to different ports of the third multi-port 15. By setting the third multi-port 15, the pipeline between the second output end of the first reversing valve 811 and the water outlet 11 and the second output end of the second reversing valve 812 and the water outlet 11 can be integrated, dividing the two longer pipelines into three shorter pipelines: one between the second output end of the first reversing valve 811 and the third multi-port 15, one between the second output end of the second reversing valve 812 and the third multi-port 15, and one between the water outlet 11 and the third multi-port 15. This reduces the difficulty of pipeline arrangement and saves space inside the brush head 04. In this embodiment, the third multi-port 15 can be a three-way valve, that is, the third multi-port 15 can have three ports, but it is not limited to this; the third multi-port 15 can also have multiple ports.

[0110] The third multi-port valve 15, the first reversing valve 811, and the second reversing valve 812 can all be located on the same side of the suction pipe 2. This arrangement reduces the distance between the third multi-port valve 15 and the first reversing valve 811 and the second reversing valve 812, facilitating the connection between the third multi-port valve 15 and the first reversing valve 811 and the second reversing valve 812.

[0111] As shown in Figures 5 to 9, the brush head 04 may further include a second liquid pump 7. The input end of the second liquid pump 7 may be connected to the water supply tank 3 for drawing cleaning water stored in the water supply tank 3. The output end of the second liquid pump 7 may be connected to the input end of the heater 4 for supplying cleaning water to the heater 4.

[0112] In some embodiments, the second liquid pump 7 can be located on the same side of the suction pipe 2 as the heater 4. This arrangement reduces the distance between the second liquid pump 7 and the heater 4, and also reduces the length of the connecting pipe between the output end of the second liquid pump 7 and the heater 4. This arrangement ensures that when the heater 4 is operating, the cleaning water output from the second liquid pump 7 can reach the heater 4 as quickly as possible, preventing the heater 4 from burning dry, thereby reducing the probability of damage to the heater 4 and improving the reliability and service life of the brush head 04.

[0113] As shown in Figures 5 to 9, the brush head 04 may further include a first liquid pump 6. The input end of the first liquid pump 6 may be connected to the water supply tank 3 for drawing liquid stored in the water supply tank 3. The output end of the first liquid pump 6 may be connected to the input end of the first reversing valve 811 for supplying cleaning water to the first reversing valve 811.

[0114] In some embodiments, the flow rate of the second liquid pump 7 may be less than the flow rate of the first liquid pump 6. The pipeline between the first liquid pump 6 and the heater 4 may have a first length, and the pipeline between the second liquid pump 7 and the heater 4 may have a second length, which may be less than the first length. Because the water supply flow rate of the second liquid pump 7 is smaller, the above arrangement prevents the first liquid pump 6 from diverting too much cleaning water due to its larger flow rate, ensuring that the second liquid pump 7 receives sufficient cleaning water and delivers it to the heater 4 in a timely manner, thus preventing the heater 4 from dry-burning.

[0115] 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 suction pipe 2. This arrangement allows the first liquid pump 6 and the first reversing valve 811 to be located on opposite sides of the suction pipe 2, and the first reversing valve 811 and the heater 4 to be located on opposite sides of the suction pipe. This increases the pipe length between the first liquid pump 6 and the heater 4, further preventing the first liquid pump 6 from diverting 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.

[0116] Furthermore, the second liquid pump 7 can be located between the heater 4 and the first liquid pump 6. This arrangement allows the distance between the second liquid pump 7 and the heater 4 to be closer, thereby further reducing the pipeline length between the second liquid pump 7 and the heater 4. This further ensures that when the heater 4 starts working, the second liquid pump 7 can deliver cleaning water to the heater 4 in a timely manner, thereby further preventing the heater 4 from burning dry. This reduces the probability of damage to the heater 4 and improves the reliability and service life of the brush head 04.

[0117] The flow rate range of the first liquid pump 6 can be from 10ml / min to 500ml / min, for example: 10ml / min, 50ml / min, 100ml / min, 150ml / min, 200ml / min, 250ml / min, 300ml / min, 350ml / min, 400ml / min, 450ml / min, 500ml / min, etc. This setting can ensure the delivery volume of the first liquid pump 6.

[0118] 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.

[0119] In some embodiments, as shown in Figures 5 to 9, 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, respectively, 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] A first number of components may be installed in the pipeline between the first multi-port 9 and the first liquid pump 6. A second number of components may be installed in the pipeline between the first multi-port 9 and the second liquid pump 7. The second number may be less than the first number, so that the clean water output from the water supply tank 3 passes through more components on its way from the first multi-port 9 to the first liquid pump 6, thereby increasing its first flow resistance and making the first flow resistance greater than the second flow resistance.

[0125] It should be noted that the components mentioned here can be: multi-port valves, valve bodies, liquid pumps, or other components with water flow capabilities.

[0126] In one embodiment, the input end of the second liquid pump 7 can be directly connected to the first multi-port 9, that is, the number of components installed on the pipeline between the second liquid pump 7 and the first multi-port 9 is 0, so as to ensure that there is a small flow resistance between the first multi-port 9 and the second liquid pump 7.

[0127] The input end of the first liquid pump 6 is connected to the first multi-port 9 via a component on the pipeline between the first multi-port 9 and the first liquid pump 6. This arrangement allows for greater flow resistance between the first multi-port 9 and the first liquid pump 6.

[0128] As shown in Figures 5 to 9, the brush head 04 may further include a second multi-port 10. The second multi-port 10 may be disposed on the pipeline between the first multi-port 9 and the first liquid pump 6. Furthermore, the second multi-port 10 may have multiple ports, and the input end of the first liquid pump 6 may be connected to the second multi-port 10. It is understood that the second multi-port 10 may be one of the components described above disposed on the pipeline between the first multi-port 9 and the first liquid pump 6.

[0129] In one embodiment, the second multi-port 10 and the first liquid pump 6 can be located on the same side of the brush head 04. For example, the second multi-port 10 and the first liquid pump 6 can be located on the same side of the suction pipe 2, thereby reducing the distance between the second multi-port 10 and the first liquid pump 6 and facilitating communication between the second multi-port 10 and the first liquid pump 6.

[0130] In some embodiments, as shown in Figures 5 to 9, the brush head 04 may further include: a pressure relief valve 16, which may be located on the same side of the suction pipe 2 as the heater 4. The first input end of the pressure relief valve 16 may be connected to the first output end of the first reversing valve 811, the second input end of the pressure relief valve 16 may be connected to the output end of the second liquid pump 7, the output end of the pressure relief valve 16 may be connected to the input end of the heater 4, and the pressure relief end of the pressure relief valve 16 may be connected to the outside of the brush head 04 for adjusting the pressure in the pipeline and preventing damage to components located in the pipeline due to excessive pressure in the pipeline.

[0131] 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.

[0132] As shown in Figures 5 to 9, 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 can 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 can have three ports, but it is not limited to this; the third multi-port 15 may also have multiple ports.

[0133] 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.

[0134] 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.

[0135] In some embodiments, as shown in Figures 5 to 9, the water supply tank 3 may be provided with a water supply connector 31, and the input end of the first liquid pump 6, the input end of the second liquid pump 7, and the first multi-port 9 may all be connected to the water supply connector 31 to connect with the water supply tank 3.

[0136] 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.

[0137] The water supply connector 31 can be close to the suction pipe 2 relative to the first reversing valve 811. This arrangement can avoid positional interference between the pipe connected to the water supply connector 31 and the pipe connected to the first reversing valve 811, and can optimize the rationality of the internal pipe layout of the brush head 04.

[0138] In some embodiments, as shown in Figures 5 to 9, the brush head 04 may further include a cleaning fluid supply chamber 20 and a third liquid pump 14. The cleaning fluid supply chamber 20 can be used to store cleaning fluid, and may be provided with a cleaning fluid supply connector 201. The input end of the third liquid pump 14 can be connected to the cleaning fluid supply connector 201, so as to communicate with the cleaning fluid supply chamber 20 through the cleaning fluid supply connector 201. The output end of the third liquid pump 14 can be connected to the second multi-port 10, and the third liquid pump 14 can draw out the cleaning fluid in the cleaning fluid supply chamber 20 through the cleaning fluid supply connector 20 and deliver it to the second multi-port 10.

[0139] In this embodiment, the second multi-port 10 can be a three-way valve, meaning it can have three ports, but is not limited to this; it can also have more than four ports. Furthermore, by positioning the second multi-port 10 between the first multi-port 9 and the first liquid pump 6, the second multi-port 10 is downstream of the first multi-port 9. The cleaning fluid output from the third liquid pump 14 enters the first liquid pump 6 after passing through the second multi-port 10, and does not enter the second liquid pump 7 through the first multi-port 9. This arrangement avoids the cleaning fluid entering the heater 4 through the second liquid pump 7, which could cause the brush head 04 to malfunction, thereby improving the reliability of the brush head 04 and enhancing the user experience.

[0140] In other embodiments, the brush head 04 may not have a second multi-port 10; instead, it may only have a first multi-port 9. The output of the third liquid pump 14 can be connected to the first multi-port 9, thereby reducing the manufacturing cost of the brush head 04 and saving internal space. In this embodiment, the first multi-port 9 can be a four-way multi-port, that is, the first multi-port 9 can have four ports, but it is not limited to this; the first multi-port 9 can also have more than four ports.

[0141] In some embodiments, as shown in Figures 5 to 9, the cleaning fluid supply connector 201 and the third pump 14 can be located on the same side of the suction pipe 2 as the first reversing valve 811 and the second reversing valve 812. This arrangement allows the first and second reversing valves 811 and 812 to be closer to the cleaning fluid supply connector 201 and the third pump 14. When the cleaning fluid enters the pipeline through the cleaning fluid supply connector 201, it can carry away the heat around the first and second reversing valves 811 and 812, thereby further reducing the heat around the first and second reversing valves 811 and 812, and further reducing the probability of malfunction or damage to the first and second reversing valves 811 and 812.

[0142] Furthermore, when the third liquid pump 14 is located on the same side of the suction pipe 2 as the first reversing valve 811 and the second reversing valve 812, the third liquid pump 14 is located on both sides of the suction pipe 2 as the first multi-port 9 and the second multi-port 10. This increases the length of the pipeline between the third liquid pump 14 and the first multi-port 9 or the second multi-port 10, allowing the pipeline between the third liquid pump 14 and the first multi-port 9 or the second multi-port 10 to cross the suction pipe 2, thereby increasing the cooling range of the cleaning liquid in the pipeline.

[0143] Meanwhile, since there are fewer components on one side of the first reversing valve 811 and the second reversing valve 812, the cleaning fluid supply connector 201 and the third liquid pump 14 can be set on the same side of the first reversing valve 811 and the second reversing 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 of components.

[0144] In other embodiments, the cleaning fluid supply connector 201 and the third liquid pump 14 may be located on the same side of the suction pipe 2 as the first multi-port 9 and the second multi-port 10. This arrangement reduces the distance between the third liquid pump 14 and the first multi-port 9 or the second multi-port 10, thereby reducing the pipe length between the third liquid pump 14 and the first multi-port 9 or the second multi-port 10, and saving on the manufacturing cost of the brush head 04.

[0145] In some embodiments, the cleaning fluid supply chamber 20 may be located inside the water supply tank 3 to improve the integration of the brush head 04. The cleaning fluid inlet of the cleaning fluid supply chamber 20 and the liquid inlet of the water supply tank 3 may be different inlets to facilitate the separate addition of cleaning fluid and liquid from the water supply tank 3.

[0146] In some embodiments, as shown in Figures 5 to 9, the heater 4 may include a heater 4 body and a first filter screen. The first filter screen may be disposed within the heater 4 body and located between the input and output ends of the heater 4 to filter the liquid within the heater 4, thereby preventing impurities from clogging the pipes and the water outlet device 1, and thus improving the service life of the brush head 04. The mesh size of the first filter screen may be 1mm to 3mm, for example: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, etc. This configuration can ensure that the first filter screen has a good filtration effect while improving its flow capacity, ensuring that water in the heater 4 can pass through the first filter screen normally, and reducing the probability of the first filter screen becoming clogged.

[0147] In one embodiment, as shown in Figures 5 to 9, the brush head 04 may further include a second filter screen 5, which may be disposed at the output end of the heater 4 or downstream of the heater 4. The mesh size of the second filter screen 5 may be smaller than that of the first filter screen. This arrangement allows the second filter screen 5 to further filter the clean water or water vapor output from the heater 4, further removing internal impurities, further reducing the probability of impurities clogging downstream pipes and the water outlet device 1, and further improving the service life of the brush head 04.

[0148] The pore size of the second filter screen 5 can be from 0.2mm to 1mm, for example: 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc. This configuration ensures that the second filter screen 5 has a good filtration effect and improves its flow capacity, guaranteeing that the clean water or steam in the heater 4 can pass through the second filter screen 5 normally.

[0149] The filtration area of ​​the second filter screen 5 can be larger than that of the first filter screen to improve the filtration effect of the second filter screen 5 and ensure that the liquid or water vapor delivered to the downstream pipeline and water outlet device 1 is free of impurities. Furthermore, by increasing the filtration area of ​​the second filter screen 5, the probability of clogging can be reduced.

[0150] The filtration area of ​​the second filter 5 can be from 500mm² to 2000mm², for example: 500mm², 600mm², 700mm², 800mm², 900mm², 1000mm², 1100mm², 1200mm², 1300mm², 1400mm², 1500mm², 1600mm², 1700mm², 1800mm², 1900mm², 2000mm², etc. This configuration ensures that the second filter 5 has sufficient filtration area and avoids the problem of excessive surface area of ​​the second filter 5 occupying too much internal space in the brush head 04, thus facilitating the miniaturization of the brush head 04.

[0151] In one embodiment, as shown in Figures 5 to 8, the brush head 04 may further include a flow detector 18. The flow detector 18 may be a flow sensor or the like. The flow detector 18 may be located between the water supply connector 31 and the first multi-way connector 9 to detect the amount of liquid output from the water supply tank 3. Furthermore, by detecting whether there is water in the pipe between the water supply connector 31 and the first multi-way connector 9, it can be determined whether the heater 4 should be turned on, to prevent the heater 4 from running dry and reducing the probability of damage to the heater 4.

[0152] In one embodiment, a preset time can be set so that the heater 4 can only be turned on when the flow detector 18 detects water in the pipe between the water supply connector 31 and the first multi-port 9 within the preset time. The preset time can be in seconds, but is not limited to this.

[0153] In one embodiment of this disclosure, as shown in Figures 5 to 9, the electrical component 8 may further include a controller 82. The controller 82 can be used to control the operation of various components within the brush head 04, such as controlling 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 located away from the cleaning component 13 relative to the heater 4, thereby further increasing the distance between the controller 82 and the heater 4, further reducing the temperature near the controller 82, and further reducing the impact of the high-temperature heat generated by the heater 4 on the controller 82. This ensures the normal operation of the controller 82, reduces the probability of damage to the controller 82, and further improves the reliability and service life of the brush head 04.

[0154] As shown in Figures 5 and 6, the brush head 04 may further include a housing 19. The housing 19 may have a receiving cavity 191, within which the controller 82 and the heater 4 can both be located. The controller 82 may be located on the side of the receiving cavity 191 furthest from the cleaning component 13, and the heater 4 may be located on the side of the receiving cavity 191 closest to the cleaning component 13. This arrangement increases the distance between the controller 82 and the heater 4, further reducing the impact of the high-temperature heat generated by the heater 4 on the controller 82. This further ensures the normal operation of the controller 82, reduces the probability of damage to the controller 82, and improves the reliability and service life of the brush head 04.

[0155] In one embodiment, the remaining components and tubing within the brush head 04 can also be located in the receiving cavity 191, thereby improving the integration of the brush head 04 and protecting the components within the brush head 04 using the housing 19, reducing the probability of damage to the components within the brush head 04 due to external forces, thereby improving the reliability and service life of the brush head 04.

[0156] In one embodiment of this disclosure, as shown in Figures 5 to 9, the brush head 04 may have multiple cleaning modes. For example, the brush head 04 may have a cold water cleaning mode, a steam cleaning mode, a hot water cleaning mode, a powerful cleaning mode, a descaling cleaning mode, and a self-cleaning mode, etc.

[0157] In cold water cleaning mode, the first liquid pump 6 can be turned on, the second liquid pump 7 and the heater 4 can be turned off, and the first reversing valve 811 connects the output end of the first liquid pump 6 with the water outlet 11, so that the cleaning water in the water supply tank 3 is delivered to the water outlet 11 through the first liquid pump 6.

[0158] In steam cleaning mode, the first liquid pump 6, the second liquid pump 7, and the heater 4 can all be turned on. The first reversing valve 811 connects the output of the first liquid pump 6 to the water outlet 11, and the second reversing valve 812 connects the output of the heater 4 to the steam output 12. This allows a portion of the cleaning water in the water supply tank 3 to be directly delivered to the water outlet 11 via the first liquid pump 6. The remaining cleaning water can be delivered to the heater 4 via the second liquid pump 7, where it is heated to form steam, which is then delivered to the steam output 12.

[0159] In hot water cleaning mode, the first liquid pump 6 and heater 4 can be turned on, the second liquid pump 7 can be turned off, the first reversing valve 811 is connected to the input end of heater 4, and the second reversing valve 812 is connected to the water outlet 11, so as to deliver the cleaning water drawn by the first liquid pump 6 to the heater 4 for heating, and deliver the heated cleaning water to the water outlet 11 through the second reversing valve 812.

[0160] In the powerful cleaning mode, the first liquid pump 6 and the heater 4 can be turned on, the second liquid pump 7 can be turned off, the first reversing valve 811 is connected to the input end of the heater 4, and the second reversing valve 812 is connected to the steam output component 12, so as to deliver the cleaning water drawn by the first liquid pump 6 to the heater 4 for heating, and deliver the heated cleaning water to the steam output component 12 through the second reversing valve 812, and deliver it to the front of the cleaning component 13 through the steam output component 12.

[0161] In descaling and cleaning mode, descaling agent can be added to the water supply tank 3, and the first liquid pump 6 can be turned on while the second liquid pump 7 and heater 4 are turned off. The first reversing valve 811 connects to the input end of heater 4, and the second reversing valve 812 connects to the water outlet 11, allowing the descaling agent to enter heater 4 for descaling. Simultaneously, the descaling agent after descaling can be delivered to the water outlet 11 via the second reversing valve 812 and discharged outside the cleaning equipment 01 through the water outlet 11, thus preventing the descaling agent from entering the steam output 12 and clogging it.

[0162] In self-cleaning mode, the second liquid pump 7 and heater 4 can be turned on, the first liquid pump 6 can be turned off, and the second reversing valve 812 is connected to the water outlet 11. The second liquid pump 7 draws cleaning water from the water supply tank 3 and heats it through the heater 4 to form water vapor. The water vapor can be delivered to the water outlet 11 through the second reversing valve 812 and then delivered to the cleaning component 13 through the water outlet 11 to moisten the cleaning component 13 and perform self-cleaning of the cleaning component 13, thereby improving the ease of use and service life of the brush head 04.

[0163] In addition, during cold water cleaning mode, steam cleaning mode, hot water cleaning mode, powerful cleaning mode, and descaling cleaning mode, the third liquid pump 14 can be turned on to deliver the cleaning liquid stored in the cleaning liquid supply chamber 20 to the first liquid pump 6, thereby improving the cleaning effect of the brush head 04.

[0164] The technical solution provided in this disclosure can achieve the following beneficial effects:

[0165] The brush head provided in this disclosure may include a suction tube, a heater, and an electrical component. The electrical component and the heater may be located on opposite sides of the suction tube, thereby creating a greater distance between them. This reduces the temperature near the electrical component and minimizes the impact of the high-temperature heat generated by the heater on the electrical component, ensuring its normal operation and reducing the probability of damage. This, in turn, improves the reliability and lifespan of the brush head.

[0166] Furthermore, the brush head provided in this disclosure utilizes a suction tube to separate the electrical components and the heater. This allows the suction tube to act as a spacer between the electrical components and the heater, thereby blocking the heat generated by the heater. This further reduces the temperature near the electrical components, further reduces the impact of the high-temperature heat generated by the heater on the electrical components, and further improves the reliability and service life of the brush head.

[0167] Meanwhile, during the operation of the brush head, there is high-speed airflow inside the suction pipe. This high-speed airflow can carry away some of the high-temperature heat generated by the heater, which can further reduce the temperature near the electrical components, further reduce the impact of the high-temperature heat generated by the heater on the electrical components, and further improve the reliability and service life of the brush head.

[0168] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
