Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a cleaning brush device and cleaning equipment. Background Technology

[0002] With the development of technology and social progress, more and more families are starting to use cleaning equipment such as vacuum cleaners, fabric cleaning machines, carpet cleaning machines, sweepers, or floor scrubbers to improve the efficiency and quality of household cleaning.

[0003] Floors, fabrics, and carpets typically exhibit a variety of levels of dirt and grime. However, most cleaning devices in related technologies offer only one cleaning mode, resulting in poor cleaning performance and a subpar user experience. Utility Model Content

[0004] This disclosure provides a cleaning brush device and cleaning equipment that can enrich cleaning modes, improve cleaning effect and user experience.

[0005] Specifically, this disclosure is achieved through the following technical solution:

[0006] According to a first aspect of the present disclosure, a cleaning brush device is provided, including at least two output components, a conduit assembly for delivering a cleaning medium to the at least two output components, and a control valve assembly. The conduit assembly includes a gas input conduit and at least two liquid input conduits, and the control valve assembly connects at least one of the input conduits to at least one of the at least two output components.

[0007] According to a second aspect of the present disclosure, a cleaning brush device is provided, including a reversing valve, two sets of output assemblies, and a piping assembly. The reversing valve has two outlets and an inlet for switching between the two outlets. The two sets of output assemblies are connected to the two outlets of the reversing valve in a one-to-one correspondence. The piping assembly includes a clean water inlet pipe, a cleaning fluid inlet pipe, and a gas inlet pipe, each connected to the inlet of the reversing valve.

[0008] According to a third aspect of the present disclosure, a cleaning brush device is provided, including a reversing valve, two sets of output components, and a piping assembly. The reversing valve has a first outlet, a second outlet, and an inlet for switching between the first outlet and the second outlet. The two sets of output components include a first output component and a second output component, the first output component being connected to the first outlet, and the second output component being connected to the second outlet. The piping assembly includes a cleaning fluid inlet pipe connected to the inlet of the reversing valve, a clean water inlet pipe connected between the first output component and the first outlet, and a gas inlet pipe connected between the second output component and the second outlet.

[0009] According to a fourth aspect of the present disclosure, a cleaning device is provided, including a control device and the aforementioned cleaning brush device, wherein the control device is electrically connected to a control valve assembly to control the opening and closing of each input pipe.

[0010] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0011] During use, the cleaning brush device disclosed herein allows each output component to output a cleaning medium for cleaning dirt. A gas input pipe can be used to supply gas to the output components. At least two liquid input pipes may include a clean water input pipe and a cleaning fluid input pipe. The clean water input pipe can be used to supply clean water to the output components, and the cleaning fluid input pipe can be used to supply cleaning fluid to the output components. A control valve assembly is used to control the connection or disconnection of each input pipe and the output components, thereby enabling at least one of the clean water input pipe, the cleaning fluid input pipe, and the gas input pipe to be connected to at least one of at least two output components. This allows the connected output components to output various cleaning media such as clean water, cleaning fluid, or foam to clean different levels of dirt, thus enabling the cleaning brush device to provide multiple cleaning modes, including clean water cleaning, cleaning fluid cleaning, and foam cleaning.

[0012] When the control valve assembly is in the clean water output mode, it outputs clean water, allowing the cleaning brush to remove easily cleaned light dirt such as dust or sweat stains. In clean water mode, the cleaning brush operates in clean water mode. When the control valve assembly is in the cleaning liquid output mode, it outputs cleaning liquid, allowing the cleaning brush to remove stubborn dirt such as oil stains, mold, or limescale. In cleaning liquid mode, the cleaning brush operates in cleaning liquid mode. When the control valve assembly is in the foam output mode, it outputs cleaning liquid foam (composed of gas and cleaning liquid) or a mixture of gas, cleaning liquid, and clean water. In mixed foam mode, the cleaning brush operates in mixed foam mode. Compared to liquids, foam has less fluidity, allowing it to adhere to vertical surfaces or complex surfaces (such as walls or corners), remaining on the dirty surface for a longer period to dissolve and clean stubborn dirt. Furthermore, when the output assembly outputs foam, users can use the foam to create different patterns on the dirt, enhancing the cleaning experience and visual appeal.

[0013] Therefore, the cleaning brush device provided in this disclosure can provide a variety of cleaning modes to be suitable for cleaning dirt of different degrees, improve the cleaning effect, meet user needs, and enhance the user experience.

[0014] Furthermore, the cleaning brush device provided in this disclosure is applicable to cleaning equipment such as vacuum cleaners, fabric cleaning machines, carpet cleaning machines, sweepers, or floor scrubbers. The cleaning equipment can automatically switch between various cleaning modes through a control device, or the cleaning equipment can switch between various cleaning modes according to user instructions. This disclosure does not impose any limitations.

[0015] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0033] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0034] If this disclosure uses terms relating to directional indications or positional relationships (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0035] With technological advancements and social progress, more and more families are using cleaning equipment such as vacuum cleaners, fabric cleaning machines, carpet cleaners, sweepers, and floor scrubbers to improve the efficiency and quality of household cleaning. Currently, there are numerous brands of cleaning equipment available for consumers to choose from. How to win consumer favor and enhance product competitiveness is an increasingly important issue for cleaning equipment manufacturers.

[0036] Taking floor scrubbers as an example, floor scrubbers are a common type of cleaning equipment. They can move across the floor and clean dirt using brushes. For instance, household floor scrubbers can be handheld and dragged by the user to clean dirty floors. Floors typically have varying degrees of dirt, including easily cleanable light dirt such as dust, hair, or sweat stains, as well as more stubborn dirt such as oil stains, limescale, or mold. However, floor scrubbers in current technology usually only have limited cleaning modes, such as water washing or cleaning liquid cleaning, which is insufficient to meet users' cleaning needs for different levels of dirt. This results in poor cleaning performance and a poor user experience.

[0037] Based on this, the present disclosure provides a cleaning brush device capable of offering multiple cleaning modes to handle different levels of dirt, improving cleaning effectiveness, meeting user needs, and enhancing the user experience. Furthermore, the cleaning brush device provided in this disclosure is not limited to floor scrubbers; it can also be used with vacuum cleaners, fabric cleaning machines, carpet cleaners, robotic vacuum cleaners, and other cleaning equipment. This disclosure makes no limitations on its application.

[0038] The cleaning brush device 10 provided in this disclosure will now be described in conjunction with the accompanying drawings.

[0039] See Figures 1 to 3 This disclosure provides a cleaning brush device 10, including at least two output components 15, a conduit assembly for supplying cleaning media to the at least two output components 15, and a control valve assembly 14. The conduit assembly includes a gas input conduit 13 and at least two liquid input conduits, and the control valve assembly 14 connects at least one of the input conduits to at least one of the at least two output components 15.

[0040] It should be noted that the output components 15 can be used to output cleaning media for cleaning dirt. There can be at least two, three, four, or five output components 15, etc. Each output component 15 can have one, two, three, four, or five output ports, etc., and this disclosure does not impose any limitations. The piping assembly is used to deliver cleaning media to each output component 15. The cleaning media includes various types such as gas, water, or cleaning liquid to address different levels of dirt. For example, the piping assembly includes a gas input pipe 13 and at least two liquid input pipes. The gas input pipe 13 can be used to deliver gas to at least one of the at least two output components 15. The at least two liquid input pipes may include a water input pipe 11 for delivering water to each output component 15 and a cleaning liquid input pipe 12 for delivering cleaning liquid to each output component 15, and this disclosure does not impose any limitations. The control valve assembly 14 is used to control the opening and closing of the piping assembly, thereby enabling at least one of the at least two output components 15 to output the corresponding cleaning media to assist the user in cleaning different levels of dirt, thus providing multiple cleaning modes. Understandably, the control valve assembly 14 may include various control valves such as shut-off valves, directional valves, or speed control valves, as long as they can control the connection and disconnection between each input pipe and the output assembly 15. This disclosure does not impose any limitations.

[0041] As an example, when the control valve assembly 14 connects one of the clean water input pipe 11, the cleaning fluid input pipe 12, and the gas input pipe 13 to at least one output assembly 15, the connected output assembly 15 can correspondingly input clean water, cleaning fluid, and gas, and the cleaning brush device 10 correspondingly provides a clean water mode, a cleaning fluid mode, and a gas mode.

[0042] Understandably, in the clean water mode, clean water can be used to wash away easily cleanable light dirt such as dust or sweat stains. The clean water can be unpolluted natural water sources such as groundwater or tap water, or domestic water. The clean water inlet pipe 11 can be connected to a tap water system to supply clean water, or the cleaning brush device 10 can have its own clean water storage tank to supply clean water; this disclosure does not impose any limitations. The cleaning brush device 10 can use clean water to clean floors or carpets awaiting cleaning, or the cleaning brush device 10 can also use clean water to clean its own cleaning brush 17.

[0043] In the cleaning fluid mode, the cleaning fluid can be used to clean stubborn dirt such as oil stains, mold, or limescale. Understandably, the cleaning fluid includes various cleaning fluids such as oil stain cleaner, floor cleaner, fabric cleaner, carpet cleaner, glass cleaner, disinfectant cleaner, or mold remover, and this disclosure does not impose any limitations. The cleaning brush device 10 can use the cleaning fluid to clean the floor or carpet awaiting cleaning, or the cleaning brush device 10 can also use the cleaning fluid to clean its own cleaning brush 17.

[0044] In gas mode, the gas can be harmless gases such as air or nitrogen, and this disclosure makes no limitation. The gas can be used to dry watermarks after cleaning or to dry the cleaning brush 17 after washing. In addition, the gas output from the output component 15 can also be used to blow away crystals that accumulate on the output component 15 after the liquid cleaning medium or foam cleaning liquid medium has dried, in order to prevent the output component 15 from becoming clogged.

[0045] As an example, when the control valve assembly 14 connects at least two of the clean water inlet pipe 11, the cleaning fluid inlet pipe 12, and the gas inlet pipe 13 to at least one output assembly 15, the connected output assembly 15 can correspondingly output a mixture of clean water and cleaning fluid, a water mist mixture of clean water and gas, a cleaning fluid foam mixture of cleaning fluid and gas, and a mixture of clean water, cleaning fluid, and gas foam. The cleaning brush device 10 correspondingly provides a mixture mode, a water mist mode, a cleaning fluid foam mode, and a mixture foam mode.

[0046] Understandably, compared to the cleaning solution mode, the concentration of cleaning solution in the mixed solution mode is lower than that in the cleaning solution mode. Essentially, the cleaning solution is diluted with water to form a mixed solution. The cleaning power of the mixed solution cleaning mode is higher than that of the water mode but lower than that of the cleaning solution mode. Users can choose to use the mixed solution cleaning mode based on the degree of dirtiness or their customized usage needs; this disclosure does not impose any limitations. Furthermore, the mixed solution cleaning mode can improve cleaning power compared to the water mode and save on cleaning solution usage compared to the cleaning solution mode.

[0047] In the water mist mode, the water disperses into a mist when impacted by air, ensuring even spraying and preventing uneven cleaning of dirt while reducing watermarks. Furthermore, in the water mist mode of the cleaning brush device 10, this disclosure does not impose any limitations on the size of the water droplets in the mist.

[0048] In foam mode, if the cleaning fluid inlet pipe 12 and the gas inlet pipe 13 are connected to at least one output component 15, the connected output component 15 outputs a cleaning fluid foam mixture of cleaning fluid and gas. If the clean water inlet pipe 11, the cleaning fluid inlet pipe 12, and the gas inlet pipe 13 are connected to at least one output component 15, the connected output component 15 outputs a mixed foam mixture of clean water, cleaning fluid, and gas. Understandably, the cleaning fluid concentration in the cleaning fluid foam is higher than that in the mixed foam. Users can choose to output either cleaning fluid foam or mixed foam based on the degree of dirtiness, and this disclosure does not impose any limitations. Furthermore, compared to the liquid cleaning mode, foam has weaker fluidity, allowing it to adhere to vertical surfaces or complex surfaces (such as walls or corners), enabling it to remain on the dirty surface for a longer period, thereby dissolving and cleaning stubborn dirt. Additionally, the output component 15 can accumulate a thicker foam layer on the dirty surface, improving the persistence of dirt decomposition and thus enhancing the cleaning effect. In addition, when the output component 15 outputs foam, users can use the foam to draw different patterns to cover the dirt, thereby increasing the fun and visual effect of cleaning.

[0049] Thus, the cleaning brush device 10 provided in this disclosure can provide multiple cleaning modes such as water mode, cleaning liquid mode, gas mode, mixed liquid mode, water mist mode, cleaning liquid foam mode, and mixed liquid foam mode, so as to enrich the cleaning modes, thereby improving the cleaning power of the cleaning brush device 10 and enriching the user experience.

[0050] The following description will use the cleaning brush device 10 with two output components 15 as an example.

[0051] See Figures 1 to 3 , Figure 1 This is a schematic diagram of a cleaning brush device 10 having two output components 15, as shown in one embodiment. Figure 2 for Figure 1 A schematic diagram of the internal structure of the cleaning brush device 10 shown. Figure 3 for Figure 1 The diagram shows another internal structure of the cleaning brush device 10. In some embodiments, the cleaning brush device 10 further includes a housing assembly 16 and a cleaning brush 17 mounted on the housing assembly 16. The cleaning brush 17 is used to clean floors or carpets awaiting cleaning. At least two output assemblies 15 include a first output assembly 15a and a second output assembly 15b mounted on the housing assembly 16. The first output assembly 15a is disposed facing the cleaning brush 17, and the second output assembly 15b is disposed facing outwards from the housing assembly 16 and inclined towards the bottom of the housing assembly 16, so that the second output assembly 15b can directly output cleaning medium to the dirt on the object to be cleaned.

[0052] Understandably, the first output component 15a includes a water spray plate, which is arranged along the length of the cleaning brush 17. The water spray plate has one or more nozzles, which are arranged along the length of the cleaning brush 17 to ensure that the output cleaning medium can make uniform contact with the cleaning brush 17. The second output component 15b includes a nozzle, which can be used to directly spray dirt to output cleaning medium at specific points and / or in measured quantities. The spray range and spray force of the nozzle can be adjusted according to user needs, and this disclosure does not specify such adjustments. Furthermore, the first output component 15a and the second output component 15b can be fixedly connected or rotatably connected to the housing component 16, respectively, to adjust the output angle of the cleaning medium, and this disclosure does not impose any limitations on this.

[0053] As described above, the first output component 15a and the second output component 15b within the cleaning brush device 10 can respectively output various cleaning media such as clean water, cleaning liquid, gas, mixed liquid, water mist, cleaning liquid foam, and mixed liquid foam, thus providing multiple cleaning modes for the cleaning brush device 10. Furthermore, the cleaning media output by the first output component 15a and the second output component 15b can be the same or different, and the first output component 15a and the second output component 15b can be used independently or in combination, allowing them to individually or in combination to form multiple cleaning modes. For example, the cleaning brush device 10 can allow the user to use one of the following modes: clean water mode, cleaning liquid mode, foam mode, mixed liquid mode, water mist mode, or gas mode. The cleaning brush device 10 can also allow the user to simultaneously use at least two of these modes simultaneously; this disclosure does not impose any limitations. In this way, the cleaning brush device 10 can enrich the cleaning modes, thereby increasing the cleaning power of the cleaning brush device 10 and improving the user experience.

[0054] Understandably, the order of use of each output component 15 is not limited in this disclosure. Users can switch each output component 15 by operating the buttons according to their own needs. Manufacturers can also install a control module in the cleaning brush device 10 or the cleaning equipment 1 adapted to the cleaning brush device 10, and adaptively switch each group of output components 15 through the setting program in the control module. This disclosure will not elaborate on this.

[0055] It should be noted that the gas inlet pipe 13, the clean water inlet pipe 11, and the cleaning fluid inlet pipe 12 can be installed inside the housing assembly 16, and the installation position of each inlet pipe inside the housing assembly 16 is not limited to... Figure 2 and Figure 3 The manufacturer can also adjust the installation position of each input pipe in the housing assembly 16 according to the actual assembly situation to form other layout structures, which are not limited in this disclosure.

[0056] Understandably, the cleaning brush device 10 may also include a mixing structure for mixing at least two cleaning media, namely water, cleaning liquid, or gas, so that the corresponding cleaning media can fully contact and mix evenly. The mixing structure may be composed of a cavity formed by the intersection of the input pipes, or it may be composed of a mixing device connected to each input pipe; this disclosure does not impose any limitations.

[0057] Understandably, the cleaning brush device 10 may also include a foamer 19 to produce rich and dense foam while conserving cleaning fluid. A drive wheel may also be provided on the housing assembly 16 of the cleaning brush device 10 to reduce the force required for the user to move the cleaning brush device 10; however, this will not be elaborated upon in this disclosure.

[0058] See Figure 4 and Figure 5 In some embodiments, to facilitate matching various cleaning modes, the control valve assembly 14 includes a first directional valve 141. The first directional valve 141 has outlets that communicate one-to-one with at least two output assemblies 15 and inlets that can selectively connect between the outlets. Each input pipe is connected to the inlet of the first directional valve 141. In one of the operating positions of the first directional valve 141, the inlet of the first directional valve 141 is connected to at least one of the outlets.

[0059] It should be noted that the first directional valve 141 can be a three-way directional valve. Two working ports of the first directional valve 141 are connected to the first output component 15a and the second output component 15b in a one-to-one correspondence. The remaining working port of the first directional valve 141 serves as an inlet for connecting to various input pipes. This disclosure does not limit the number of working positions of the first directional valve 141. Manufacturers can configure it according to user requirements; for example, the first directional valve 141 can be a two-position three-way valve or a three-position three-way valve, etc.

[0060] Furthermore, in other embodiments, the first reversing valve 141 may also have multiple inlets, each inlet corresponding to and connected to a specific input pipe. This disclosure does not impose any limitations on this. For example, when the piping assembly includes one gas input pipe 13 and two liquid input pipes, the first reversing valve 141 may be a five-way reversing valve. Alternatively, the first reversing valve 141 may also be configured as a six-way reversing valve to accommodate communication with other components of the cleaning brush device 10; this disclosure will not elaborate further.

[0061] See Figures 4 to 6 In some embodiments, to facilitate the connection between each input pipe and the first reversing valve 141, the cleaning brush device 10 further includes a connecting component 18. The connecting component 18 can be used to connect each input pipe to the inlet of the first reversing valve 141, and the connecting component 18 can also be used to pre-mix the cleaning medium in each input pipe before entering the first reversing valve 141.

[0062] As an example, see Figure 5 The connection component 18 includes a first connector 181, each input pipe is connected to the first connector 181, and the first connector 181 is also connected to the inlet of the first reversing valve 141.

[0063] It should be noted that when the pipeline assembly includes a gas input pipeline 13, a clean water input pipeline 11, and a cleaning fluid input pipeline 12, the first connector 181 can be a four-way pipe joint. One port of the four-way pipe joint is connected to the inlet of the first reversing valve 141, and the other three ports of the four-way pipe joint are respectively connected to the gas input pipeline 13, the clean water input pipeline 11, and the cleaning fluid input pipeline 12.

[0064] In other examples, see 6. To facilitate matching various cleaning modes, when the piping assembly includes a gas input pipe 13, a clean water input pipe 11, and a cleaning fluid input pipe 12, the connection assembly 18 includes a second connector 182 and a third connector 183. Two of the three input pipes are respectively connected to the second connector 182, and the second connector 182 is also connected to the third connector 183. The remaining one of the three input pipes and the inlet of the first reversing valve 141 are respectively connected to the third connector 183.

[0065] For example, the second connector 182 and the third connector 183 are both tee fittings. One port of the third connector 183 can be connected to the inlet of the first reversing valve 141, and another port of the third connector 183 can be connected to any one of the three input pipes (gas input pipe 13, clean water input pipe 11, and cleaning liquid input pipe 12). Another port of the third connector 183 can be connected to one port of the second connector 182, and the other two ports of the second connector 182 can be connected to the other two of the three input pipes (gas input pipe 13, clean water input pipe 11, and cleaning liquid input pipe 12) one by one.

[0066] Thus, the connection component 18 facilitates the connection of each input pipe to the inlet of the first reversing valve 141, thereby simplifying the structure of the first reversing valve 141. Furthermore, the connection component 18 allows the cleaning medium in each input pipe to be pre-mixed before entering the first reversing valve 141, enabling the cleaning brush device 10 to achieve multiple cleaning modes.

[0067] Understandably, there are no restrictions on the diameter of each input pipe, and the connection component 18 can be matched and set according to the diameter of each pipe.

[0068] See Figures 4 to 6In some embodiments, to facilitate the delivery of cleaning medium from each input pipe to the output component 15, at least two liquid input pipes include a clean water input pipe 11 and a cleaning liquid input pipe 12. The cleaning brush device 10 also includes a water pump 11a acting on the clean water input pipe 11, so that starting and stopping the water pump 11a corresponds to opening or closing the clean water input pipe 11. And / or, the cleaning brush device 10 also includes a cleaning liquid pump 12a acting on the cleaning liquid input pipe 12, so that starting and stopping the cleaning liquid pump 12a corresponds to opening or closing the cleaning liquid input pipe 12. And / or, the cleaning brush device 10 also includes an air pump 13a acting on the gas input pipe 13, so that starting and stopping the air pump 13a corresponds to opening or closing the gas input pipe 13.

[0069] Understandably, water pump 11a powers the clean water inlet pipe 11 and can be connected to the clean water tank 30. Cleaning fluid pump 12a powers the cleaning fluid inlet pipe 12 and can be connected to the cleaning fluid tank 40. Air pump 13a powers the gas inlet pipe 13 and can be connected to the atmosphere. Understandably, each pump has a built-in valve to prevent fluid backflow.

[0070] In some embodiments, the cleaning device 1 is a floor scrubber, with the cleaning brush device 10 serving as the floor brush part. A clean water tank 30 is typically provided on the main body 20 of the floor scrubber, and a clean water inlet pipe 112 connects to the clean water tank 30. When the floor scrubber is in use, the main body 20 is typically integrated with the scrubber handle. As the user moves the scrubber by holding the handle, the main body 20 and the floor brush are typically tilted, allowing the clean water in the clean water tank 30 to fall to the output component 15 due to gravity. Therefore, the clean water inlet pipe 11 can omit the installation of a water pump 11a. Of course, in some embodiments, when the floor scrubber is used lying flat, the handle and the floor brush are arranged in a straight line for cleaning small spaces such as under beds, sofas, or cabinets. In this case, a water pump 11a can also be installed on the clean water inlet pipe 11, providing power for clean water delivery to the clean water inlet pipe 112.

[0071] It should also be noted that the clean water tank 30 can also be installed on the cleaning brush device 10, and this disclosure does not impose any restrictions. Furthermore, to facilitate the supply of cleaning fluid, a cleaning fluid tank 40 can be installed inside the housing assembly 16 of the cleaning brush device 10, and the cleaning fluid inlet pipe 122 can be connected to the cleaning fluid tank 40 to supply cleaning fluid. The type of cleaning fluid can be changed according to the user's needs, and this disclosure does not impose any restrictions.

[0072] See Figure 6The cleaning brush device 10 includes a first reversing valve 141, two output components 15, and a piping assembly. The reversing valve has two outlets and an inlet that switches between the two outlets. The two sets of output components 15 are connected to the two outlets of the reversing valve in a one-to-one correspondence. The piping assembly includes a clean water inlet pipe 11, a cleaning fluid inlet pipe 12, and a gas inlet pipe 13, which are respectively connected to the inlet of the reversing valve.

[0073] The clean water input pipe 112, the cleaning liquid input pipe 122, and the gas input pipe 132 are connected to one inlet of the first reversing valve 141 through the connecting assembly 18. The clean water input pipe 112 is equipped with a water pump 11a, the cleaning liquid input pipe 122 is equipped with a cleaning liquid pump 12a, and the gas input pipe 132 is equipped with a gas pump 13a.

[0074] The two sets of output components 15 include a first output component 15a and a second output component 15b. The first output component 15a is disposed toward the cleaning brush 17 of the cleaning brush device 10. The second output component 15b is disposed toward the outside of the cleaning brush device 10 and is inclined toward the bottom of the cleaning brush device 10 so as to be able to directly output the cleaning medium onto the floor or carpet waiting to be cleaned.

[0075] It should be noted that the first directional valve 141 is configured as a three-way directional valve. In one of the operating positions of the first directional valve 141, the inlet of the first directional valve 141 is connected to at least one outlet of the first directional valve 141, thereby connecting the corresponding output component 15. For example, if the inlet of the first directional valve 141 is connected to one outlet of the first directional valve 141, then the first output component 15a or the second output component 15b can be used independently. If the inlet of the first directional valve 141 is connected to both outlets of the first directional valve 141, then the first output component 15a and the second output component 15b can be used in combination. Thus, the user can choose the use of each output component 15 according to their usage requirements, and this disclosure does not impose any restrictions.

[0076] See Figure 6 As an example, the first directional valve 141 includes a two-position three-way valve.

[0077] In the first operating position of the first reversing valve 141, the inlet of the first reversing valve 141 is connected to the outlet of the first output component 15a, while the outlet of the first reversing valve 141 connected to the second output component 15b is closed. At this time, the first output component 15a can output cleaning medium to the cleaning brush 17. During routine use of the cleaning brush device 10, the first reversing valve 141 can be in the first operating position to connect the first output component 15a, allowing the cleaning brush device 10 to clean dirt using the cleaning brush 17. For example, with a floor scrubber, the user can move the floor scrubber and use its roller brush to clean the floor.

[0078] In the first operating position of the first reversing valve 141, one or more of the water pump 11a, the cleaning fluid pump 12a, and the air pump 13a can be started respectively, so that the first output component 15a can switch between various cleaning modes.

[0079] Specifically, if only the water pump 11a is activated in the cleaning brush device 10, while the cleaning liquid pump 12a and the air pump 13a are deactivated, the first output component 15a can output clean water to the cleaning brush 17, and the cleaning brush device 10 is in clean water mode. For example, the clean water mode can be used to wet the cleaning brush 17 with clean water to clean light dirt on floors or carpets, or the clean water mode can also be used to self-clean the cleaning brush 17 that is attached to the cleaning brush device 10 itself, to rinse off dirt from the cleaning brush 17.

[0080] If only the cleaning fluid pump 12a is activated in the cleaning brush device 10, while the water pump 11a and air pump 13a are deactivated, the first output component 15a can output cleaning fluid to the cleaning brush 17. The cleaning brush device 10 is then in cleaning fluid mode to enhance the cleaning power of the cleaning brush device 10 on surfaces such as floors or carpets awaiting cleaning, or to enhance the cleaning power of the cleaning brush 17. Typically, the cleaning fluid has a certain degree of fluidity. When the cleaning fluid is applied to relatively flat surfaces such as floors, glass, or kitchen countertops, it can flow across the surface to dissolve and clean dirt. This enhances cleaning power and makes it suitable for cleaning large areas of stubborn dirt. When the cleaning fluid is applied to carpets or fabric surfaces awaiting cleaning, it can also penetrate deep into the stains to dissolve stubborn dirt, thereby increasing cleaning power.

[0081] If both the water pump 11a and the cleaning liquid pump 12a are activated in the cleaning brush device 10, and the air pump 13a is deactivated, then the first output component 15a can output a mixed liquid to the cleaning brush 17, and the cleaning brush device 10 is in mixed liquid mode. Understandably, compared to the cleaning liquid mode, the concentration of the cleaning liquid in the mixed liquid mode is lower. Essentially, the cleaning liquid is diluted with water to form a mixed liquid. The cleaning power of the mixed liquid cleaning mode is higher than that of the water mode but lower than that of the cleaning liquid mode. Users can choose to use the mixed liquid cleaning mode according to the degree of dirt or their customized usage needs; this disclosure does not impose any limitations. Furthermore, the mixed liquid cleaning mode can improve cleaning power compared to the water mode and save on cleaning liquid usage compared to the cleaning liquid mode.

[0082] If the water pump 11a and air pump 13a of the cleaning brush device 10 are activated, and the cleaning liquid pump 12a is deactivated, the first output component 15a can evenly output water mist to the cleaning brush 17, and the cleaning brush device 10 is in water mist mode. Understandably, the water mist mode ensures even water spraying, avoiding uneven cleaning of dirt and reducing watermark residue. This disclosure does not limit the size of the water droplets in the water mist.

[0083] If the cleaning brush device 10 has the cleaning liquid pump 12a and air pump 13a activated, and the water pump 11a deactivated, the first output component 15a can output cleaning liquid foam to the cleaning brush 17. If the cleaning brush device 10 has the water pump 11a, cleaning liquid pump 12a, and air pump 13a activated, the first output component 15a can output mixed liquid foam to the cleaning brush 17, and the cleaning brush device 10 is in foam mode. Understandably, the cleaning liquid concentration in the cleaning liquid foam is higher than that in the mixed liquid foam. Users can choose to output either cleaning liquid foam or mixed liquid foam according to the degree of dirt, and this disclosure does not impose any limitations. Compared to liquids, foam has weaker fluidity, thus it can adhere to vertical surfaces or complex surfaces (such as walls or corners), allowing the foam to remain on the dirty surface for a long time, thereby dissolving and cleaning stubborn dirt. Furthermore, the output component 15 can accumulate a thicker foam layer on the dirty surface, improving the persistence of dirt decomposition and thus enhancing the cleaning effect. In addition, when the first output component 15a outputs foam, users can also use the foam to draw different patterns to cover the dirt, thereby increasing the fun and visual effect of cleaning.

[0084] If the air pump 13a of the cleaning brush device 10 is activated, and the cleaning liquid pump 12a and water pump 11a are deactivated, the first output component 15a can output gas to the cleaning brush 17, and the cleaning brush device 10 is in gas mode to dry the cleaning brush 17 or blow away crystals on the first output component 15a. Understandably, the output gas can be air or a harmless gas such as nitrogen. On one hand, the gas output by the output component 15 can be used to dry residual cleaning water marks on floors or carpets, or the gas blown out by the output component 15 can also be used to dry the cleaning brush 17. That is, after cleaning the cleaning brush 17 after use, the cleaning brush device 10 can dry the cleaning brush 17 by blowing out gas from the output component 15. On the other hand, the gas output by the output component 15 can be used to blow away crystals accumulated on the output component 15 after the water, cleaning liquid, mixture, or foam has dried, to prevent the output component 15 from becoming clogged and to ensure that the cleaning brush device 10 can normally output the corresponding cleaning medium.

[0085] In the second operating position of the first directional valve 141, the inlet of the first directional valve 141 is connected to the outlet of the second output component 15b, while the outlet of the first directional valve 141 connected to the first output component 15a is closed. At this time, the second output component 15b can directly spray cleaning media onto specific dirt points for targeted cleaning. Of course, when distributing cleaning media to specific dirt points, the output volume of the cleaning media can be quantitatively set according to user needs; this disclosure does not impose any limitations.

[0086] Specifically, one or more of the water pump 11a, cleaning fluid pump 12a, and air pump 13a can be started respectively, so that the second output component 15b can switch between various cleaning modes, so that the second output component 15b can output clean water, cleaning fluid, gas, mixture, foam or water mist accordingly, which will not be described in detail in this disclosure.

[0087] See Figure 7 As an example, the first output component 15a and the second output component 15b can be used simultaneously. In this case, the first directional valve 141 includes a three-position three-way valve. Figure 6 The difference in the structure shown is that, in Figure 7 In the neutral position of the first directional valve 141, the inlet of the first directional valve 141 is connected to both outlets of the first directional valve 141, allowing the first output component 15a and the second output component 15b of the cleaning brush device 10 to simultaneously output cleaning media. Thus, in Figure 7 When the first reversing valve 141 is in the neutral position, the cleaning brush device 10 can use the cleaning brush 17 to clean dirt, and can also directly spray cleaning medium onto the floor or carpet during the cleaning process to improve cleaning power.

[0088] Of course, in other embodiments, when the first directional valve 141 includes a three-position three-way valve, the middle position of the first directional valve 141 can also be set to a normally closed working position, that is, in the middle position of the first directional valve 141, the inlet of the first directional valve 141 and the two outlets of the first directional valve 141 are not connected, so that the first output component 15a and the second output component 15b are both in the closed state. This disclosure does not impose any restrictions.

[0089] See Figure 6 and Figure 7In some embodiments, the cleaning brush device 10 further includes a foam generator. When cleaning liquid and gas enter the foam generator, the foam generator can mix the two to produce abundant cleaning liquid foam. Alternatively, when water, cleaning liquid, and gas enter the foam generator, the foam generator can mix the three to produce abundant mixed liquid foam, thereby improving the foam generation effect. It is understood that the foam generator can be connected between the first output component 15a and the corresponding outlet of the first reversing valve 141, and / or the foam generator can also be connected between the second output component 15b and the corresponding outlet of the first reversing valve 141; this disclosure does not impose any limitations.

[0090] See Figures 8 to 10 In some embodiments, the first output component 15a and the second output component 15b can also output different cleaning media when used in combination, further enriching the cleaning modes of the cleaning brush device 10. In this case, the control valve assembly 14 includes a second directional valve 142, which has at least three working ports, including a first outlet connected to the first output component 15a, a second outlet connected to the second output component 15b, and an inlet selectively connected between the first and second outlets. At least two liquid input pipes include a clean water input pipe 11 and a cleaning fluid input pipe 12. One of the three input pipes is connected to the inlet of the second directional valve 142, and the remaining two are connected to the first output component 15a and the second output component 15b respectively. In one of the working positions of the second directional valve 142, the inlet of the second directional valve 142 is connected to the first outlet and / or the second outlet.

[0091] It should be noted that, in Figure 9 In the cleaning brush device shown, any one of the clean water input pipe 11, the cleaning liquid input pipe 12, and the gas input pipe 13 can be connected to the inlet of the second reversing valve 142, and the remaining two input pipes can be directly connected to the first output component 15a and the second output component 15b respectively.

[0092] For example, with Figure 9 For example, the clean water input pipe 11 is directly connected to the first output component 15a, and the gas input pipe 13 is directly connected to the second output component 15b. The cleaning fluid input pipe 12 is connected to the inlet of the second reversing valve 142. Thus, the second reversing valve 142 can control the connection between the cleaning fluid input pipe 12 and the first output component 15a and / or the second output component 15b, thereby forming different cleaning modes.

[0093] With this configuration, the clean water mode, as the regular cleaning mode, can be directly connected to the first output component 15a, enabling the first output component 15a to output clean water to the cleaning brush 17. The cleaning modes of the cleaning brush device 10 can be enriched simply by adding a cleaning fluid input pipe 12 and a gas input pipe 13 to the existing pipe design for the clean water mode.

[0094] In some embodiments, to facilitate communication between each input pipe and the second reversing valve 142 and each output component 15, the cleaning brush device 10 further includes a fourth connector 184, which connects the first outlet, the first output component 15a, and the clean water input pipe 11. The cleaning brush device 10 also includes a fifth connector 185, which connects the second outlet, the second output component 15b, and the gas input pipe 13.

[0095] It should be noted that the fourth connector 184 allows the clean water and cleaning fluid to be pre-mixed to form a mixture before entering the first input component. The fifth connector 185 allows the cleaning fluid and gas to be pre-mixed before entering the second output component 15b.

[0096] In some embodiments, the cleaning brush device 10 further includes a foam generator connected between the second output component 15b and the fifth connector 185, thereby facilitating the generation of abundant foam in foam mode.

[0097] See Figure 9 As an example, the second directional valve 142 includes a two-position three-way valve. A water pump 11a is provided on the clean water input pipe 11. A cleaning fluid pump 12a is provided on the cleaning fluid input pipe 12, and an air pump 13a is provided on the gas input pipe 13. The inlet of the second directional valve 142 is connected to the cleaning fluid input pipe 122. The clean water input pipe 112 is connected between the first outlet and the first output assembly 15a via a fourth connector 184. The gas input pipe 132 is connected between the second outlet and the second output assembly 15b via a fifth connector 185. The second directional valve 142 has two normally open operating positions. In the first operating position, the inlet of the second directional valve 142 is connected to the first outlet, and the second outlet of the first directional valve 141 is closed. In the second operating position, the inlet of the second directional valve 142 is connected to the second outlet, and the first outlet of the second directional valve 142 is closed.

[0098] Understandably, for Figure 9In the daily use of the cleaning brush device 10, the second reversing valve 142 can be in the first working position to activate the first output component 15a, allowing the cleaning brush device 10 to clean dirt using the cleaning brush 17. At this time, both the clean water inlet pipe 112 and the cleaning fluid inlet pipe 122 are connected to the first output component 15a. If the water pump 11a is started and the cleaning fluid pump 12a is turned off, the first output component 15a can output clean water to the cleaning brush 17, and the cleaning brush device 10 is in clean water mode. If the water pump 11a is turned off and the cleaning fluid pump 12a is started, the first output component 15a can output cleaning fluid to the cleaning brush 17, and the cleaning brush device 10 is in cleaning fluid mode. If both the water pump 11a and the cleaning fluid pump 12a are started, the first output component 15a can output a mixed solution to the cleaning brush 17, and the cleaning brush device 10 is in mixed solution mode. Furthermore, when the second reversing valve 142 is in its first operating position, although the second outlet of the second reversing valve 142 is closed and the cleaning fluid cannot enter the second output component 15b, the gas input pipe 13 can still be connected to the second output component 15b, so the air pump 13a can also be started, causing the second output component 15b to output gas. At this time, the gas mode of the cleaning brush device 10 can be combined with any of the following: water mode, cleaning fluid mode, or mixed fluid mode. In this way, the first output component 15a and the second output component 15b can be used simultaneously and output different cleaning media respectively, so that the cleaning brush device 10 can combine different cleaning modes.

[0099] Thus, when the control valve assembly 14 is in the mixed liquid output state and the gas output state, the inlet of the second reversing valve 142 is connected to the first outlet, and the water pump 11a, the cleaning liquid pump 12a, and the air pump 13a are started, enabling the first output assembly 15a to output the mixed liquid and the second output assembly 15b to output the gas. When the control valve assembly 14 is in the cleaning liquid output state and the gas output state, the inlet of the second reversing valve 142 is connected to the first outlet, and the cleaning liquid pump 12a and the air pump 13a are started, while the cleaning liquid pump 12a is turned off, enabling the first output assembly 15a to output the cleaning liquid and the second output assembly 15b to output the gas. When the control valve assembly 14 is in the clean water output state and the gas output state, the inlet of the second reversing valve 142 can be connected to either the first outlet or the second outlet, the water pump 11a and the gas input pipe 13 are started, and the cleaning liquid pump 12a is turned off, enabling the first output assembly 15a to output the clean water and the second output assembly 15b to output the gas. Taking a floor scrubber as an example, when the user cleans the floor with the wet cleaning brush 17, the floor scrubber can also blow air during the cleaning process to dry the water marks, speed up the drying of the floor, and reduce the drying time. Of course, in other embodiments, the air pump 13a may not be started, and this disclosure does not impose any restrictions.

[0100] Understandably, for Figure 9The cleaning brush device 10 shown can be configured to operate in a second working position when the user requires targeted cleaning of dirt. This allows the second reversing valve 142 to activate the second output component 15b, enabling the cleaning brush device 10 to directly output cleaning medium to the location of the dirt for targeted cleaning. At this time, both the cleaning fluid input pipe 122 and the gas input pipe 132 are connected to the second output component 15b. If the cleaning fluid is activated and the air pump 13a is deactivated, the second output component 15b can spray cleaning fluid onto the location of the dirt, and the cleaning brush device 10 is in cleaning fluid mode. If both the cleaning fluid pump 12a and the air pump 13a are activated, the second output component 15b can spray cleaning fluid foam onto the location of the dirt, and the cleaning brush device 10 is in foam mode. If the air pump 13a is started, the second output component 15b can spray air towards the location of the dirt to dry the cleaning traces, or the second output component 15b can blow away residual cleaning fluid crystals on the second output component 15b to prevent clogging, and the cleaning brush 17 is in gas mode. Furthermore, when the second reversing valve 142 is in its second operating position, although the first outlet of the second reversing valve 142 is closed and cleaning fluid cannot enter the first output component 15a, the clean water inlet pipe 112 can still be connected to the first output component 15a, so the water pump 11a can also be started, causing the first output component 15a to output clean water to the cleaning brush 17. At this time, the clean water mode of the cleaning brush device 10 can be combined with any of the gas mode, cleaning fluid mode, or foam mode. Thus, the first output component 15a and the second output component 15b can be used simultaneously, each outputting a different cleaning medium, allowing the cleaning brush device 10 to combine different cleaning modes. Of course, in other embodiments, the water pump 11a may not be started, and this disclosure does not impose any restrictions.

[0101] Thus, when the control valve assembly 14 is in the foam output state and the clean water output state, the inlet and the second outlet of the second reversing valve 142 are connected, and the water pump 11a, the cleaning liquid pump 12a, and the air pump 13a are started, enabling the second output assembly 15b to output foam and the first output assembly 15a to output clean water. When the control valve assembly 14 is in the cleaning liquid output state and the clean water output state, the inlet and the second outlet of the second reversing valve 142 are connected, the water pump 11a and the cleaning liquid pump 12a are started, and the air pump 13a is turned off, enabling the second output assembly 15b to output cleaning liquid and the first output assembly 15a to output clean water. Taking a floor scrubber as an example, when the user cleans the floor with the cleaning brush 17 moistened with clean water, the floor scrubber can also spray cleaning liquid or foam at specific points on stubborn dirt during the cleaning process to increase the cleaning power of the floor scrubber and save cleaning liquid. Of course, in other embodiments, the water pump 11a may not be started, and the floor scrubber may only perform point spraying operations; this disclosure does not impose any limitations.

[0102] Understandably, the fourth connector 184 and the fifth connector 185 can be tee fittings, respectively. Figure 9 The cleaning brush device 10 may also include a foam generator, which may be connected between the second output assembly 15b and the second outlet of the second reversing valve 142.

[0103] See Figure 10 As an example, the second directional valve 142 includes a three-position three-way valve. Figure 9 The difference in the structure shown is that, in Figure 10 The second directional valve 142 is in the neutral position, with its inlet connected to both the first and second outlets. Thus, the cleaning fluid input pipe 122 can simultaneously connect to the first output component 15a and the second output component 15b. At this time, if the water pump 11a, cleaning fluid pump 12a, and air pump 13a are all started, the first output component 15a of the cleaning brush device 10 can output the mixed liquid, and the second output component 15b can output cleaning fluid foam. In this way, the cleaning brush device 10 can both use the cleaning brush 17, soaked in the mixed liquid, to clean dirt, and can also directly spray foam onto surfaces such as floors or carpets during the cleaning process, thereby enhancing the cleaning power of the cleaning brush device 10 and enriching its cleaning modes. At this time, in Figure 10 When the second reversing valve 142 is in the neutral position, if the cleaning liquid pump 12a is closed and both the water pump 11a and the air pump 13a are started, the first output component 15a and the second output component 15b of the cleaning brush device 10 can also output water mist at the same time, which will not be described in detail in this disclosure.

[0104] Of course, in Figure 10 In the neutral position of the second reversing valve 142 shown, if the water pump 11a and air pump 13a are started and the cleaning liquid pump 12a is closed, the first output component 15a of the cleaning brush device 10 can output clean water, and the second output component 15b can output gas, which will not be described in detail in this disclosure. Alternatively, in Figure 10 When the second reversing valve 142 is in the neutral position, if the cleaning fluid pump 12a is started and the water pump 11a and air pump 13a are closed, the first output component 15a and the second output component 15b of the cleaning brush device 10 can both output cleaning fluid, which will not be described in detail in this disclosure.

[0105] See Figure 11In some embodiments, to facilitate communication between the clean water input pipe 11 and the second output component 15b, the control valve assembly 14 further includes a first control valve 143. The inlet of the first control valve 143 is connected between the clean water input pipe 11 and the fourth connector 184, and the outlet of the first control valve 143 is connected to the second output component 15b. Thus, when the cleaning liquid pump 12a and the air pump 13a are off, opening the water pump 11a and the first control valve 143 allows the second output component 15b to also output clean water. When the cleaning liquid pump 12a and / or the air pump 13a are correspondingly open, if the water pump 11a and the first control valve 143 are also open, the second output component 15b can also correspondingly output a mixture, water mist, or a mixture foam, which will not be elaborated further in this disclosure. It is understood that the first control valve 143 can be a shut-off valve.

[0106] See Figure 11 In some embodiments, to facilitate communication between the gas input pipe 13 and the first output component 15a, the control valve assembly 14 further includes a second control valve 144. The inlet of the second control valve 144 is connected between the gas input pipe 13 and the sixth connector 186, and the outlet of the second control valve 144 is connected to the first output component 15a. Thus, when the water pump 11a and the cleaning fluid pump 12a are off, opening the air pump 13a and the second control valve 144 can also enable the first output component 15a to output gas. When the water pump 11a and / or the cleaning fluid pump 12a are respectively open, if the air pump 13a and the second control valve 144 are also open, the first output component 15a can also output water mist, cleaning fluid foam, or mixed foam, which will not be elaborated further in this disclosure.

[0107] See Figure 12 In some embodiments, in addition to the three-way directional valve described above, the control valve assembly 14 can also be configured as a four-way directional valve. In this case, the cleaning brush device 10 includes at least two output assemblies 15, a pipe assembly, a sixth connector 186, and a third directional valve 145.

[0108] At least two output components 15 include a first output component 15a and a second output component 15b. The piping assembly includes a gas input pipe 13, a clean water input pipe 11, and a cleaning fluid input pipe 12. The third reversing valve 145 has at least four working ports, including two outlets and two inlets. The two outlets are connected to the first output component 15a and the second output component 15b in a one-to-one correspondence. One of the two inlets is connected to the sixth connector 186, and the other of the two inlets is connected to one of the three input pipes. The remaining two of the three input pipes are each connected to the sixth connector 186.

[0109] The third directional valve 145 includes at least one of the following operating positions:

[0110] In one of the operating positions of the third directional control valve 145, one of the two inlets is connected to one of the two outlets. In one of the operating positions of the third directional control valve 145, one of the two inlets is connected to both outlets respectively. In one of the operating positions of the third directional control valve 145, each of the two inlets is connected to one of the two outlets respectively. In one of the operating positions of the third directional control valve 145, each of the two inlets is connected to one outlet in a one-to-one correspondence. In one of the operating positions of the third directional control valve 145, both inlets and both outlets are connected.

[0111] As an example, in Figure 12 In the cleaning brush device 10 shown, the example is that the clean water input pipe 11 is connected to one of the two inlets, and the cleaning liquid input pipe 12 and the gas input pipe 13 are respectively connected to the sixth connector 186.

[0112] In one of the operating positions of the third directional valve 145, one of the two inlets is connected to one of the two outlets. At this time, if the inlet connected to the clean water input pipe 11 is connected to the first outlet, and both the other inlet and the second outlet are closed, the first output assembly 15a can output clean water to the cleaning brush 17. If the inlet connected to the sixth connector 186 is connected to the first outlet, and both the other inlet and the second outlet are closed, the first output assembly 15a can output cleaning fluid, gas, or foam. The same applies when one of the two inlets is connected to the second outlet, and this will not be elaborated upon in this disclosure.

[0113] In one of the operating positions of the third directional valve 145, one of the two inlets is connected to both outlets. At this time, if the inlet connected to the clean water input pipe 11 is connected to both the first and second outlets, and the other inlet is closed, then the first output assembly 15a and the second output assembly 15b can simultaneously output clean water. If the inlet connected to the sixth connector 186 is connected to both the first and second outlets, and the other inlet is closed, then the first output assembly 15a and the second output assembly 15b can output cleaning fluid, gas, or foam.

[0114] In one of the operating positions of the third directional valve 145, the two inlets are connected to one of the two outlets respectively. At this time, if both inlets are connected to the first outlet and the second outlet is closed, the first output assembly 15a can output clean water, cleaning fluid, gas, mixture, water mist, or foam. If both inlets are connected to the second outlet and the first outlet is closed, the second output assembly 15b can output clean water, cleaning fluid, gas, mixture, water mist, or foam.

[0115] In one of the working positions of the third directional valve 145, the two inlets are connected to the two outlets respectively, so the first output component 15a can output clean water and the second output component 15b can output cleaning liquid, gas or foam.

[0116] In one of the operating positions of the third directional valve 145, both inlets and both outlets are open, so the first output component 15a and the second output component 15b can output clean water, cleaning liquid, gas, mixture, water mist or foam.

[0117] Of course, in other embodiments, when the cleaning brush device 10 has at least two sets of output components 15, each output component 15 may be positioned toward the cleaning brush 17, or each output component 15 may be positioned toward the ground or carpet waiting to be cleaned, and this disclosure does not impose any limitations.

[0118] See Figure 13 In addition to the cleaning brush device 10 described above, this disclosure also provides a cleaning device 1. The cleaning device 1 includes a control device and any of the cleaning brush devices 10 described above, and a control valve assembly 14 is electrically connected to the control device to control the opening and closing of each input pipe.

[0119] It should be noted that the control device can be used to set cleaning programs, enabling the control valve assembly 14 to automatically switch between various cleaning modes according to the set cleaning programs, thereby improving the intelligence of the equipment. The control device can also be used to customize cleaning modes, allowing the control valve assembly 14 to switch between various cleaning modes according to user input commands, in order to adapt to various user needs.

[0120] As an example, the cleaning device 1 also includes a main unit 20, and a control device including operation buttons installed on the main unit 20 and a controller electrically connected to the operation buttons.
