Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a cleaning device. 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, providing users with limited choices and resulting in a poor user experience. Utility Model Content

[0004] This disclosure provides a cleaning device that can enrich cleaning modes and improve the 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 device is provided, including a clean water delivery assembly, a cleaning liquid delivery assembly, a gas delivery assembly, a control valve assembly, and an output assembly. The clean water delivery assembly, the cleaning liquid delivery assembly, and the gas delivery assembly are connected to the output assembly through the control valve assembly, so that the output assembly can output at least three of clean water, cleaning liquid, mixed liquid, sparkling water, and foam.

[0007] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0008] The cleaning equipment provided in this disclosure, during use, includes an output component that can output cleaning media to clean dirt. A clean water delivery component can deliver clean water to the output component, a cleaning liquid delivery component can deliver cleaning liquid to the output component, and a gas delivery component can deliver gas to the output component. A control valve component controls the connection or disconnection between each delivery component and the output component, thereby enabling at least one of the clean water delivery component, cleaning liquid delivery component, and gas delivery component to connect with the output component. This allows the output component to output at least three different cleaning media, including clean water, cleaning liquid, mixed solution, aerated water, and foam, to address different levels of dirt cleaning. This enriches the cleaning modes of the equipment, providing users with multiple cleaning modes to choose from and enhancing the user experience.

[0009] Thus, the cleaning equipment provided in this disclosure can offer a variety of cleaning modes to be suitable for cleaning different levels of dirt, improve cleaning effect, meet user needs, and enhance user experience.

[0010] Furthermore, the cleaning equipment 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.

Detailed Implementation

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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 offer limited cleaning modes, such as water washing or detergent cleaning, providing users with few options and failing to meet their cleaning needs for different levels of dirt, resulting in a poor user experience.

[0036] Based on this, the present disclosure provides a cleaning device capable of offering multiple cleaning modes to suit different levels of dirt, meeting user needs and improving user experience. Furthermore, the cleaning device provided by the present disclosure is not limited to floor scrubbers, but can also be used with vacuum cleaners, fabric cleaning machines, carpet cleaning machines, robotic vacuum cleaners, and other cleaning devices; the present disclosure makes no limitations on its application.

[0037] The cleaning equipment 1 provided in this disclosure will now be described with reference to the accompanying drawings.

[0038] See Figure 1 and Figure 2 This disclosure provides a cleaning device 1, including a clean water delivery assembly 11, a cleaning liquid delivery assembly 12, a gas delivery assembly 13, a control valve assembly 14, and an output assembly 15. The clean water delivery assembly 11, the cleaning liquid delivery assembly 12, and the gas delivery assembly 13 are connected to the output assembly 15 through the control valve assembly 14, enabling the output assembly 15 to output at least three of the following: clean water, cleaning liquid, mixed liquid, sparkling water, and foam.

[0039] It should be noted that the output component 15 can be used to output cleaning media for cleaning dirt. The clean water delivery component 11 can be used to deliver clean water to the output component 15, the cleaning liquid delivery component 12 can be used to deliver cleaning liquid to the output component 15, and the gas delivery component 13 can be used to deliver gas to the output component 15. The control valve component 14 is used to control the connection or disconnection between each delivery component and the output component 15, thereby enabling at least one of the clean water delivery component 11, the cleaning liquid delivery component 12, and the gas delivery component 13 to be connected to the output component 15. This allows the output component 15 to output at least three different cleaning media from clean water, cleaning liquid, mixed liquid, sparkling water, and foam to correspond to different levels of dirt, thus enabling the cleaning device 1 to provide multiple cleaning modes and improve the user experience.

[0040] 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 conveying component and the output component 15. This disclosure does not impose any limitations. For example, the control valve assembly 14 may be one or more directional valves connected between each conveying component and the output component 15, or it may be multiple shut-off valves connected one-to-one between each conveying component and the output component 15, or it may be a combination of shut-off valves and directional valves connected between each conveying component and the output component 15. This disclosure does not impose any limitations.

[0041] Therefore, the cleaning device 1 provided by this disclosure can provide multiple cleaning modes to be suitable for cleaning dirt of different degrees, improve the cleaning effect, meet user needs, and enhance the user experience.

[0042] See Figure 1 and Figure 2 In some embodiments, to enrich the cleaning modes of the cleaning device 1, the cleaning device 1 includes at least one of the following cleaning modes:

[0043] When the control valve assembly 14 is in the clean water output state, the clean water delivery assembly 11 is connected to the output assembly 15, while the cleaning fluid delivery assembly 12 and the gas delivery assembly 13 are disconnected from the output assembly 15. At this time, the output assembly 15 can output clean water, and the cleaning device 1 can use the clean water to clean easily cleanable light dirt such as dust or sweat stains; the cleaning device 1 is in clean water mode. Understandably, the clean water can be unpolluted natural water sources such as groundwater or tap water, or domestic water. The clean water delivery assembly 11 can be connected to a tap water system to fill with clean water, or the clean water delivery assembly 11 can have its own clean water storage tank; this disclosure does not impose any limitations.

[0044] When the control valve assembly 14 is in the cleaning fluid output state, the cleaning fluid delivery assembly 12 is connected to the output assembly 15, while the clean water delivery assembly 11 and the gas delivery assembly 13 are disconnected from the output assembly 15. At this time, the output assembly 15 can output cleaning fluid, and the cleaning device 1 can use the cleaning fluid to clean stubborn dirt such as oil stains, mold, or limescale. The cleaning device 1 is in cleaning fluid mode. 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. Generally, the cleaning fluid has a certain degree of fluidity. When the cleaning fluid is output to a relatively flat surface to be cleaned, such as a floor, glass, or kitchen countertop, the cleaning fluid can flow on the surface to dissolve and clean the dirt. This not only increases the cleaning power but also makes it suitable for cleaning large areas of stubborn dirt. When the cleaning fluid is output to a carpet or fabric surface to be cleaned, the cleaning fluid can also penetrate deep into the stains to dissolve stubborn stains, thereby increasing the cleaning power.

[0045] When the control valve assembly 14 is in the foam output state, the cleaning liquid delivery assembly 12 and the gas delivery assembly 13 are connected to the output assembly 15, and the clean water delivery assembly 11 is disconnected from the output assembly 15, or the clean water delivery assembly 11, the cleaning liquid delivery assembly 12, and the gas delivery assembly 13 are connected to the output assembly 15. The gas delivered by the gas delivery assembly 13 can be air or nitrogen, or other gases capable of producing foam with the cleaning liquid and / or clean water; this disclosure does not impose any limitations. When the cleaning liquid delivery assembly 12 and the gas delivery assembly 13 are connected to the output assembly 15, the output assembly 15 can output cleaning liquid foam generated by the mixture of cleaning liquid and gas, and the cleaning device 1 is in cleaning liquid foam mode. When the clean water delivery assembly 11, the cleaning liquid delivery assembly 12, and the gas delivery assembly 13 are connected to the output assembly 15, the output assembly 15 can output mixed liquid foam generated by the mixture of clean water, cleaning liquid, and gas, and the cleaning device 1 is in mixed liquid foam mode. Understandably, the concentration of cleaning solution in the cleaning solution foam is higher than that in the mixed solution foam. Users can choose to output either cleaning solution foam or mixed solution foam according to the degree of dirtiness, and this disclosure does not impose any restrictions.

[0046] Thus, cleaning device 1 can use foam to clean stubborn dirt. Compared to liquids, foam has less 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. Furthermore, the output component 15 can build up a thicker layer of foam on the dirty surface, improving the persistence of dirt breakdown and thus enhancing the cleaning effect. In addition, when the output component 15 outputs foam, the user can use the foam to draw different patterns on the dirt, increasing the fun and visual appeal of the cleaning process.

[0047] When the control valve assembly 14 is in the mixed liquid output state, the clean water delivery assembly 11 and the cleaning liquid delivery assembly 12 are connected to the output assembly 15, while the gas delivery assembly 13 is disconnected from the output assembly 15. At this time, the output assembly 15 can output a mixture of clean water and cleaning liquid, and the cleaning device 1 is in mixed liquid mode. Understandably, compared to the cleaning liquid mode, the concentration of cleaning liquid in the mixed liquid mode is lower than that in the cleaning liquid mode. Essentially, the cleaning liquid is diluted with clean water to form a mixed liquid. The cleaning power of the mixed liquid cleaning mode is higher than that of the clean 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 clean water mode and save on cleaning liquid usage compared to the cleaning liquid mode.

[0048] When the control valve assembly 14 is in the bubble water output state, the gas delivery assembly 13 and the clean water delivery assembly 11 are connected to the output assembly 15, while the cleaning liquid delivery assembly 12 is disconnected from the output assembly 15. At this time, the output assembly 15 can output bubble water formed by the mixture of clean water and gas, and the cleaning device 1 is in bubble water mode. Understandably, when clean water and gas are simultaneously supplied to the output assembly 15, the clean water will disperse and form bubble water due to the impact of the gas, thereby making the clean water spray evenly, avoiding uneven cleaning of dirt and reducing watermark residue. Furthermore, in the bubble water mode of the cleaning device 1, this disclosure does not limit the size of the water droplets in the bubble water.

[0049] When the control valve assembly 14 is in the gas output state, the gas delivery assembly 13 is connected to the output assembly 15, while the clean water delivery assembly 11 and the cleaning liquid delivery assembly 12 are disconnected from the output assembly 15. At this time, the output assembly 15 can output gas, and the cleaning device 1 is in gas mode. Understandably, the output gas can be air or a harmless gas such as nitrogen. On one hand, the gas output by the output assembly 15 can be used to dry residual cleaning water marks on the floor or carpet, etc., to dry the floor or carpet, etc., or the gas blown out by the output assembly 15 can also be used to dry the cleaning brush 17. That is, after the cleaning device 1 has cleaned the cleaning brush 17 after use, it can also dry the cleaning brush 17 by the gas blown out by the output assembly 15. On the other hand, the gas output by the output assembly 15 can be used to blow away crystals accumulated on the output assembly 15 after the clean water, cleaning liquid, mixture, or foam has dried, to prevent the output assembly 15 from becoming clogged and to ensure that the cleaning device 1 can output the corresponding cleaning medium normally.

[0050] It should also be noted that the order in which the various cleaning modes provided by cleaning device 1 are used is not limited in this disclosure. For example, users can switch between various cleaning modes by operating buttons according to their own needs. Furthermore, manufacturers can also install a control module in cleaning device 1 or a compatible cleaning device 1. The control module can identify the degree of dirt through devices such as cameras or light sensors, and adaptively switch between various cleaning modes according to the identified degree of dirt. Alternatively, the control module can have a built-in program that switches between various cleaning modes according to a preset program; this disclosure does not limit this.

[0051] As an example, the clean water mode of cleaning device 1 can be activated later than the mixed liquid mode, cleaning liquid mode, or foam mode, so that cleaning device 1 can clean the dirt dissolved by the cleaning liquid with clean water, or cleaning device 1 can rinse the cleaning brush 17 after use with clean water to prevent dirt from corroding and damaging the cleaning brush 17. Of course, the clean water mode can also be activated earlier than the mixed liquid mode, cleaning liquid mode, or foam mode for pre-cleaning dirt, and this disclosure does not impose any limitations.

[0052] Therefore, based on the content mentioned above, Figure 1 The output component 15 in the cleaning device 1 shown can output various cleaning media such as clean water, cleaning liquid, gas, mixed liquid, sparkling water, cleaning liquid foam and mixed liquid foam, so as to enrich the cleaning mode of the cleaning device 1, thereby improving the cleaning power of the cleaning device 1 and enriching the user experience.

[0053] See Figure 1 and Figure 2 As shown, in other embodiments, it is understood that the cleaning fluid may include a liquid containing a surfactant (such as sodium stearate, sodium lauryl sulfate, sodium dodecylbenzene sulfonate, polyoxyethylene ether, or cocamidopropyl betaine), or a liquid without a surfactant (e.g., a plant-based cleaning fluid or an alcohol-based disinfectant cleaning fluid). When the cleaning fluid does not contain a surfactant, mixing the cleaning fluid with gas can generate a bubble cleaning fluid, and the gas action can make the cleaning fluid output by the output component sprayed more evenly. When the cleaning fluid contains a surfactant, mixing the cleaning fluid with gas can generate foam containing the cleaning fluid, which will not be described in detail in this disclosure.

[0054] See Figures 1 to 3 In some embodiments, to facilitate the delivery of cleaning media between the various delivery components, the clean water delivery component 11 includes a clean water inlet pipe 112, the cleaning fluid delivery component 12 includes a cleaning fluid inlet pipe 122 and a cleaning fluid delivery power component 121 acting on the cleaning fluid inlet pipe 122, and the gas delivery component 13 includes a gas inlet pipe 132 and a gas delivery power component 131 acting on the gas inlet pipe 132. A control valve component 14 operates between the clean water inlet pipe 112, the cleaning fluid inlet pipe 122, the gas inlet pipe 132, and the output component 15.

[0055] It should be noted that cleaning equipment 1 is as follows: Figure 3Taking the floor scrubber shown as an example, the cleaning equipment 1 includes a cleaning brush device 10 and a main body device 20. A clean water tank 30 is usually provided on the main body device 20 of the floor scrubber, and a clean water input pipe 112 can be connected to the clean water tank 30. In use, the main body device 20 of the floor scrubber is usually integrated with the floor scrubber handle. When the user holds the handle and moves the floor scrubber, the main body device 20 and the floor brush are usually tilted, so that the clean water in the clean water tank 30 can fall to the output component 15 for output by gravity potential energy. Therefore, the clean water delivery component 11 can be omitted from the installation of the clean water delivery power component 111. Of course, in some embodiments, the clean water delivery assembly 11 may include a clean water delivery power component 111 acting on the clean water input pipe 112 to meet the user's flexible clean water access needs. Alternatively, when the floor scrubber is used lying flat, the scrubber handle and the floor brush are arranged in a straight line for cleaning small spaces such as under beds, sofas, or cabinets, and the clean water delivery power component 111 can also provide clean water delivery power to the clean water input pipe 112. Of course, in other embodiments, the clean water tank 30 may also be installed on the cleaning brush device 10, and this disclosure does not impose any limitations.

[0056] It should also be noted that, for ease of supplying cleaning solution, a cleaning solution tank 40 can be installed inside the cleaning device 1. The cleaning solution inlet pipe 122 can be connected to the cleaning solution tank 40 to supply cleaning solution. The type of cleaning solution can be changed according to the user's needs, and this disclosure does not impose any restrictions. Accordingly, the cleaning solution tank 40 can be installed on the cleaning brush device 10 or on the main device 20, and this disclosure does not impose any restrictions.

[0057] Understandably, the clean water delivery power component 111 can be configured as a clean water pump, the cleaning fluid delivery power component 121 can be configured as a cleaning fluid pump, and the gas delivery power component 131 can be configured as an air pump or a blower, etc., and this disclosure does not impose any limitations. The gas delivery power component 131 can be connected to the atmosphere. Understandably, the control valve assembly 14 includes shut-off valves corresponding to each input pipe, or the control valve assembly 14 includes directional valves connected to each input pipe and the output assembly 15, or the control valve assembly 14 includes a combination of shut-off valves and directional valves, and this disclosure does not impose any limitations. Correspondingly, the valve body on each input pipe can be integrated with the corresponding pump body or set independently, and this disclosure does not impose any limitations.

[0058] In addition, to facilitate the connection of each input pipe and control valve assembly 14, the cleaning equipment 1 may also include a connection component, which may include a two-way pipe joint, a three-way pipe joint, or a four-way pipe joint, etc. The interface of each pipe joint may be set according to the pipe diameter of each input pipe or the interface size of the control valve assembly 14, and this disclosure does not impose any restrictions.

[0059] See Figure 1 and Figure 2In some embodiments, to adapt to various cleaning modes, the output component 15 may include a nozzle, a water spray pipe, or a water spray plate, etc. The output component 15 may be positioned towards the cleaning brush 17 of the cleaning device 1, or towards the floor or carpet awaiting cleaning. Accordingly, the output component 15 may be fixedly connected to the housing of the cleaning device 1. Alternatively, the output component 15 may be rotatably connected to the housing of the cleaning device 1 to adjust the orientation of the output component 15, which is not limited in this disclosure.

[0060] See Figure 4 and Figure 5 In some embodiments, to enrich the cleaning modes of the cleaning device 1, the output component 15 is provided with at least two sets, and each output component 15 is connected to the clean water delivery component 11, the cleaning liquid delivery component 12 and the gas delivery component 13 through the control valve component 14 respectively.

[0061] It should be noted that the output components 15 can be configured in two, three, four, or five groups, and each output component 15 can have one, two, three, four, or five output ports, etc., without limitation in this disclosure. At least a portion of at least two groups of output components 15 can be positioned towards the cleaning brush 17 of the cleaning device 1 to wet the cleaning brush 17 to clean dirt, or to wash dirt off the cleaning brush 17. Another portion of at least two groups of output components 15 can be positioned towards the surface to be cleaned by the cleaning brush 17, allowing the output components 15 to directly output cleaning medium to the floor or carpet awaiting cleaning. Thus, each part of the output components 15 can be used individually or in combination, thereby enabling the various cleaning modes of the cleaning device 1 to be used individually or in combination. In other words, the cleaning device 1 can provide the user with one of the following modes: water mode, cleaning liquid mode, foam mode, mixed liquid mode, sparkling water mode, or gas mode. The cleaning device 1 can also provide the user with at least two of the following modes simultaneously: water mode, cleaning liquid mode, foam mode, mixed liquid mode, sparkling water mode, or gas mode. This disclosure does not impose any restrictions.

[0062] Understandably, when the cleaning device 1 has at least two sets of output components 15, the order of use of each output component 15 is not limited in this disclosure. Users can switch each set of output components 15 by operating the buttons according to their own needs. Manufacturers can also install a control module in the cleaning device 1 or a cleaning device 1 adapted to the cleaning device 1, and adaptively switch each set of output components 15 through the setting program in the control module. This disclosure will not elaborate on this.

[0063] Understandably, when the cleaning device 1 has at least two sets of output components 15, to facilitate matching one or more of the cleaning modes, the control valve assembly 14 may include a reversing valve. This reversing valve may have inlets corresponding to each conveying component and outlets corresponding to each output component 15. Each inlet of the reversing valve can be selectively connected to each outlet via its valve core, enabling the cleaning device 1 to provide a variety of cleaning modes. As an example, when there are two sets of output components 15, the reversing valve may have three inlets corresponding to each conveying component and two outlets corresponding to each output component 15; that is, the reversing valve may be a multi-position five-way valve. When there are three sets of output components 15, the reversing valve may be a multi-position six-way valve. The manufacturer can set the number of positions of the reversing valve according to user requirements; for example, it may be a two-position five-way valve or a three-position five-way valve, etc., and this disclosure does not impose any limitations. Accordingly, the reversing valve can also be configured as other multi-position multi-way valves to accommodate communication with other components of the cleaning equipment 1, and this disclosure does not impose any limitations.

[0064] Of course, in other embodiments, when the cleaning device 1 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.

[0065] See Figure 4 and Figure 6 In some embodiments, to enrich the cleaning modes of the cleaning device 1 and simplify the structure of the control valve assembly 14, the output assembly 15 is provided with at least two sets. The control valve assembly 14 includes a first reversing valve 141, which has an outlet corresponding to each output assembly 15 and an inlet selectively connected between the outlets. The cleaning device 1 also includes a connecting assembly 18, through which the inlet of the first reversing valve 141 is connected to the clean water delivery assembly 11, the cleaning liquid delivery assembly 12, and the gas delivery assembly 13 respectively. In one of the working positions of the first reversing valve 141, the inlet of the first reversing valve 141 is connected to at least one outlet of the first reversing valve 141, thereby connecting the corresponding output assembly 15.

[0066] It should be noted that the connecting component 18 is used to connect the clean water delivery component 11, the cleaning liquid delivery component 12, and the gas delivery component 13 to the inlet of the first reversing valve 141, so as to reduce the number of inlets of the first reversing valve 141 and simplify the structure of the control valve assembly 14.

[0067] As an example, the connection assembly 18 may include a four-way connector, one port of which is connected to the inlet of the first directional valve 141, and the other three ports of which are respectively connected to the clean water delivery assembly 11, the cleaning fluid delivery assembly 12, and the gas delivery assembly 13. Alternatively, the connection assembly may also include two three-way connectors 181, one port of which is connected to the inlet of the first directional valve 141, another port of which is connected to any one of the three delivery assemblies (clean water delivery assembly 11, cleaning fluid delivery assembly 12, and gas delivery assembly 13), another port of which is connected to one port of the second three-way connector 181, and the other two ports of the second three-way connector 181 are respectively connected to the other two of the three delivery assemblies (clean water delivery assembly 11, cleaning fluid delivery assembly 12, and gas delivery assembly 13). Thus, the number of inlets of the first directional valve 141 can be reduced by connecting component 18. The first directional valve 141 only needs to have one inlet and an outlet that is connected to each conveying component. The inlet of the first directional valve 141 can be selectively connected between each outlet to simplify the structure of the first directional valve 141 and enable the cleaning equipment 1 to achieve multiple cleaning modes.

[0068] Understandably, the pipe diameter in each conveying component is not limited, and the connecting component 18 can be matched according to the pipe diameter of each pipe. Understandably, when there are two sets of output components 15, the first reversing valve 141 can have an inlet and two outlets that are connected to each output component 15 in a one-to-one manner; that is, the first reversing valve 141 can be a two-position three-way valve or a three-position three-way valve, etc. When there are three sets of output components 15, the first reversing valve 141 can be a two-position four-way valve or a three-position four-way valve, etc., and this disclosure does not impose any restrictions.

[0069] The following explanation will take cleaning equipment 1 with two sets of output components 15 as an example.

[0070] See Figure 7 and Figure 8The cleaning equipment 1 includes a clean water delivery assembly 11, a cleaning fluid delivery assembly 12, a gas delivery assembly 13, a control valve assembly 14, and two sets of output assemblies 15. The clean water delivery assembly 11 includes a clean water input pipe 112 and a clean water delivery power component 111 acting on the clean water input pipe 112. The cleaning fluid delivery assembly 12 includes a cleaning fluid input pipe 122 and a cleaning fluid delivery power component 121 acting on the cleaning fluid input pipe 122. The gas delivery assembly 13 includes a gas input pipe 132 and a gas delivery power component 131 acting on the gas input pipe 132. The control valve assembly 14 includes a first directional valve 141. The clean water input pipe 112, the cleaning fluid input pipe 122, and the gas input pipe 132 are connected to the inlet of the first directional valve 141 via a connecting assembly 18. The two sets of output assemblies 15 are connected to the two outlets of the first directional valve 141 respectively.

[0071] It should be noted that 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 positioned towards the cleaning brush 17 of the cleaning device 1. The second output component 15b is positioned towards the surface to be cleaned by the cleaning brush 17, enabling the cleaning medium to be directly output onto the floor or carpet awaiting cleaning. For example, the second output component 15b may be positioned towards the outside of the cleaning device 1, and the second output component 15b may be tilted towards the bottom of the cleaning device 1 to correspond to the surface to be cleaned.

[0072] Understandably, 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. 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 and 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 needs, and this disclosure does not impose any restrictions.

[0073] See Figure 7 As an example, the first directional control valve 141 includes a two-position three-way valve. In the first operating position of the first directional control valve 141, the inlet of the first directional control valve 141 is connected to the outlet of the first output component 15a, and the outlet of the first directional control valve 141 connected to the second output component 15b is closed. In the second operating position of the first directional control valve 141, the inlet of the first directional control valve 141 is connected to the outlet of the second output component 15b, and the outlet of the first directional control valve 141 connected to the first output component 15a is closed.

[0074] It should be noted that during routine use of the cleaning equipment 1, the first reversing valve 141 can be in the first working position to activate the first output component 15a, allowing the cleaning equipment 1 to clean dirt using the cleaning brush 17. Taking a floor scrubber as an example, the user can move the scrubber and use its roller brush to clean the floor. Furthermore, when the user requires targeted cleaning of dirt, the first reversing valve 141 can also be in the second working position to activate the second output component 15b, allowing the cleaning equipment 1 to directly output cleaning media to the location of the dirt for targeted cleaning. Of course, when outputting cleaning media to specific locations, the output volume of the cleaning media can be quantitatively set according to user needs, and this disclosure does not impose any limitations.

[0075] Specifically, when the first reversing valve 141 includes a two-position three-way valve, in the first working position of the first reversing valve 141, the second output component 15b is in the closed state, and the first output component 15a can output cleaning medium to the cleaning brush 17 of the cleaning device 1, so that the cleaning brush 17 can clean dirt. At this time, one or more of the clean water delivery power component 111, the cleaning liquid delivery power component 121, and the gas delivery power component 131 can be started respectively, so that the first output component 15a can switch between various cleaning modes. Taking the clean water delivery power component 111 as a clean water pump, the cleaning liquid delivery power component 121 as a cleaning liquid pump, and the gas delivery power component 131 as an air pump as an example, if only the clean water pump is started in the cleaning device 1, the first output component 15a can output clean water to the cleaning brush 17, and the cleaning device 1 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 awaiting cleaning, or the clean water mode can also self-clean the cleaning brush 17 itself to rinse away dirt. Correspondingly, if only the cleaning liquid pump is activated in the cleaning device 1, the first output component 15a can output cleaning liquid to the cleaning brush 17, and the cleaning device 1 is in cleaning liquid mode to enhance the cleaning power of the cleaning device 1 on floors or carpets awaiting cleaning, or to enhance the cleaning power of the cleaning brush 17. If both the clean water pump and the cleaning liquid pump are activated in the cleaning device 1, the first output component 15a can output a mixed solution to the cleaning brush 17, and the cleaning device 1 is in mixed solution mode. If both the clean water pump and the air pump are activated in the cleaning device 1, the first output component 15a can evenly output sparkling water to the cleaning brush 17, and the cleaning device 1 is in sparkling water mode. If the cleaning device 1 has a cleaning fluid pump and an air pump activated, the first output component 15a can output cleaning fluid foam to the cleaning brush 17. If the cleaning device 1 has a water pump, a cleaning fluid pump, and an air pump activated, the first output component 15a can output mixed foam to the cleaning brush 17, and the cleaning device 1 is in foam mode. If the cleaning device 1 has an air pump activated, the first output component 15a can output gas to the cleaning brush 17, and the cleaning device 1 is in gas mode to dry the cleaning brush 17 or blow away crystals on the first output component 15a.

[0076] When the first directional valve 141 includes a two-position three-way valve, in the second working position of the first directional valve 141, the first output component 15a is in the closed state, and the second output component 15b can directly output cleaning medium to the ground or carpet waiting to be cleaned. The cleaning equipment 1 has a targeted spraying function for dirt. Correspondingly, one or more of the clean water delivery power component 111, the cleaning liquid delivery power component 121, and the gas delivery power component 131 can be activated 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 liquid, gas, mixed liquid, foam or aerated water accordingly. This disclosure will not elaborate further.

[0077] See Figure 8 As an example, the first directional valve 141 includes a three-position three-way valve. Figure 7 The difference in the structure shown is that, in Figure 8 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 device 1 to simultaneously output cleaning media. Thus, in Figure 8 When the first reversing valve 141 is in the neutral position, the cleaning device 1 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 the cleaning power.

[0078] Of course, in other embodiments, when the first directional valve 141 includes a three-position three-way valve, in the middle position of the first directional valve 141, the inlet of the first directional valve 141 and both 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, which is not limited in this disclosure.

[0079] See Figure 7 and Figure 8 In some embodiments, the cleaning device 1 further includes a foam generator. When the cleaning agent and gas enter the foam generator, the foam generator can mix the two to produce abundant cleaning agent foam. Alternatively, when water, cleaning agent, 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.

[0080] See Figure 9In some embodiments, the first output component 15a and the second output component 15b can also output different cleaning media respectively, so that the various cleaning modes of the cleaning device 1 can be used in combination, further enriching the cleaning modes of the cleaning device 1. As an example, the control valve assembly 14 includes a second reversing valve 142, which has a first outlet, a second outlet, and an inlet that selectively connects to either the first outlet or the second outlet. The first outlet is connected to the first output component 15a, the second outlet is connected to the second output component 15b, and the inlet of the second reversing valve 142 is connected to the cleaning liquid delivery assembly 12. The cleaning device 1 also includes a first connector 182 and a second connector 183. The clean water delivery assembly 11 is connected between the first output component 15a and the first outlet through the first connector 182, and the gas delivery assembly 13 is connected between the second output component 15b and the second outlet through the second connector 183.

[0081] It should be noted that when the inlet of the second reversing valve 142 is connected to the first outlet and disconnected from the second outlet, both the clean water delivery assembly 11 and the cleaning fluid delivery assembly 12 are connected to the first output assembly 15a, and the gas delivery assembly 13 is connected to the second output assembly 15b. Thus, the first output assembly 15a can output clean water, cleaning fluid, and a mixture to the cleaning brush 17, and the second output assembly 15b can output gas, enabling the cleaning device 1 to be used in combination with multiple cleaning modes. When the inlet of the second reversing valve 142 is connected to the second outlet and disconnected from the first outlet, the clean water delivery assembly 11 is connected to the first output assembly 15a, and both the cleaning fluid delivery assembly 12 and the gas delivery assembly 13 are connected to the second output assembly 15b. Thus, the first output assembly 15a can output clean water to the cleaning brush 17, and the second output assembly 15b can output cleaning fluid, gas, or cleaning fluid foam, enabling the cleaning device 1 to be used in combination with multiple cleaning modes.

[0082] See Figure 10As an example, the second directional valve 142 includes a two-position three-way valve. The clean water delivery assembly 11 includes a clean water inlet pipe 112 and a clean water delivery power component 111 acting on the clean water inlet pipe 112. The cleaning fluid delivery assembly 12 includes a cleaning fluid inlet pipe 122 and a cleaning fluid delivery power component 121 acting on the cleaning fluid inlet pipe 122. The gas delivery assembly 13 includes a gas inlet pipe 132 and a gas delivery power component 131 acting on the gas inlet pipe 132. The inlet of the second directional valve 142 is connected to the cleaning fluid inlet pipe 122. The clean water inlet pipe 112 is connected between the first outlet and the first output assembly 15a via a first connector 182. The gas inlet pipe 132 is connected between the second outlet and the second output assembly 15b via a second connector 183. The second directional valve 142 has two 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 of the second directional valve 142, the inlet and the second outlet of the second directional valve 142 are connected, and the first outlet of the second directional valve 142 is closed.

[0083] Understandably, for Figure 10 In the cleaning device 1 shown, during routine use, the second reversing valve 142 can be in the first operating position to activate the first output component 15a, allowing the cleaning device 1 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 clean water pump is started and the cleaning fluid pump is stopped, the first output component 15a can output clean water to the cleaning brush 17. If the clean water pump is stopped and the cleaning fluid pump is started, the first output component 15a can output cleaning fluid to the cleaning brush 17. If both the clean water pump and the cleaning fluid pump are started, the first output component 15a can output a mixture to the cleaning brush 17. Furthermore, when the second reversing valve 142 is in the first operating position, although the second outlet of the second reversing valve 142 is closed, preventing the cleaning fluid from entering the second output component 15b, the gas delivery component 13 can still be connected to the second output component 15b, allowing the air pump to start and causing the second output component 15b to output gas. 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 device 1 can combine different cleaning modes.

[0084] 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 clean water delivery power component 111, the cleaning liquid delivery power component 121, and the gas delivery power component 131 are activated, enabling the first output component 15a to output the mixed liquid and the second output component 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 delivery power component 121 and the gas delivery power component 131 are activated, while the cleaning liquid delivery power component 121 is closed, enabling the first output component 15a to output the cleaning liquid and the second output component 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 the first outlet or the second outlet, the clean water delivery power component 111 and the gas delivery assembly 13 are activated, and the cleaning liquid delivery power component 121 is closed, so that the first output assembly 15a can output clean water and the second output assembly 15b can output 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 cleaning water marks, speed up the drying of the floor, and reduce the drying time of the floor. Of course, in other embodiments, the air pump may not be activated, and this disclosure does not impose any restrictions.

[0085] Understandably, for Figure 10The cleaning device 1 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 device 1 to directly output cleaning medium to the location of the dirt for targeted cleaning. At this time, both the cleaning fluid inlet pipe 122 and the gas inlet pipe 132 are connected to the second output component 15b. If the cleaning fluid pump is activated and the air pump is deactivated, the second output component 15b can spray cleaning fluid onto the location of the dirt. If both the cleaning fluid pump and the air pump are activated, the second output component 15b can spray cleaning fluid foam onto the location of the dirt. If the air pump is activated, the second output component 15b can spray gas onto the location of the dirt to dry cleaning marks, or it can spray gas to remove residual cleaning fluid crystals to prevent clogging. 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 the cleaning fluid cannot enter the first output component 15a, the clean water input pipe 112 can still be connected to the first output component 15a. Therefore, the clean water pump can also be started, allowing the first output component 15a to output clean water to the cleaning brush 17. In this way, the first output component 15a and the second output component 15b can be used simultaneously, each outputting different cleaning media, enabling the cleaning device 1 to combine different cleaning modes. Of course, in other embodiments, the clean water pump may not be started, and this disclosure does not impose any limitations.

[0086] 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 clean water delivery power component 111, the cleaning fluid delivery power component 121, and the gas delivery power component 131 are activated, enabling the second output component 15b to output foam and the first output component 15a to output clean water. When the control valve assembly 14 is in the cleaning fluid output state and the clean water output state, the inlet and the second outlet of the second reversing valve 142 are connected, the clean water delivery power component 111 and the cleaning fluid delivery power component 121 are activated, and the gas delivery power component 131 is closed, enabling the second output component 15b to output cleaning fluid and the first output component 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 fluid or foam at specific points on stubborn dirt during the cleaning process to increase the cleaning power of the floor scrubber and save on the use of cleaning fluid. Of course, in other embodiments, the water pump may not be started, and the floor scrubber may only perform spot cleaning operations; this disclosure does not impose any restrictions.

[0087] Understandably, the first connector 182 and the second connector 183 can be tee fittings, respectively. Figure 10The cleaning device 1 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.

[0088] See Figure 11 As an example, the second directional valve 142 includes a three-position three-way valve. Figure 10 The difference in the structure shown is that, in Figure 11 The second directional valve 142 is in the neutral position, with its inlet connected to both the first and second outlets. Thus, in... Figure 11 With the second reversing valve 142 in its neutral position, the cleaning fluid inlet pipe 122 can simultaneously connect to the first output component 15a and the second output component 15b. At this time, if the water pump, cleaning fluid pump, and air pump are all activated, the first output component 15a of the cleaning device 1 can output the mixed liquid, and the second output component 15b can output cleaning fluid foam. Thus, the cleaning device 1 can not only use the cleaning brush 17 soaked in the mixed liquid to clean dirt, but also directly spray foam onto surfaces such as floors or carpets during the cleaning process, thereby enhancing the cleaning power of the cleaning device 1 and enriching its cleaning modes.

[0089] Of course, in Figure 11 In the neutral position of the second reversing valve 142 shown, if the clean water pump and air pump are started and the cleaning liquid pump is turned off, the first output component 15a and the second output component 15b of the cleaning device 1 can simultaneously output sparkling water, which will not be described in detail in this disclosure. Alternatively, in Figure 11 When the second reversing valve 142 is in the neutral position, if the cleaning fluid pump is started and the clean water pump and air pump are shut off, both the first output component 15a and the second output component 15b of the cleaning device 1 can output cleaning fluid, which will not be described in detail in this disclosure.

[0090] See Figure 12 In some embodiments, to facilitate control of the cleaning medium output by each output component 15, the control valve assembly 14 further includes a first control valve 143. The first control valve 143 is connected between the clean water input pipe 112 and the first connector 182, allowing the cleaning device 1 to control the on / off state of the clean water input pipe 112 and the first output component 15a via the first control valve 143, thereby flexibly controlling the cleaning medium output by the first output component 15a. And / or, the control valve assembly 14 further includes a second control valve 144, which is connected between the gas input pipe 132 and the second connector 183, allowing the cleaning device 1 to control the on / off state of the gas input pipe 132 and the second output component 15b via the second control valve 144. Thus, the cleaning device 1 can flexibly control the cleaning medium output by each output component 15 to form multiple cleaning modes, enriching the user experience. Further details are omitted in this disclosure.

[0091] Understandably, the first control valve 143 and the second control valve 144 can be two shut-off valves, two speed control valves, or two pressure control valves, etc. The first control valve 143 and the second control valve 144 can also be two directional control valves, each of which can also be used to connect other pipelines of the cleaning equipment 1; this disclosure does not impose any limitations. The first control valve 143 and the second control valve 144 can also be a combination of a shut-off valve and a directional control valve; this disclosure does not impose any limitations.

[0092] See Figure 13 In some embodiments, to further enrich the cleaning modes of the cleaning device 1, the control valve assembly 14 further includes a third control valve 145, and the cleaning device 1 further includes a third connector 184. The inlet of the third control valve 145 is connected between the clean water delivery assembly 11 and the first control valve 143 through the third connector 184, and the outlet of the third control valve 145 is connected between the second output assembly 15b and the second connector 183. It should be noted that... Figure 12 The cleaning equipment shown is different from the cleaning equipment 1 shown. Figure 13 The clean water delivery component 11 of the cleaning equipment 1 can also be connected to the second output component 15b, so that the second output component 15b can also output clean water, mixed liquid, sparkling water or mixed liquid foam.

[0093] See Figure 13 In some embodiments, to further enrich the cleaning modes of the cleaning device 1, the control valve assembly 14 further includes a fourth control valve 146, and the cleaning device 1 further includes a fourth connector 185. The inlet of the fourth control valve 146 is connected between the gas delivery assembly 13 and the second control valve 144 through the fourth connector 185, and the outlet of the fourth control valve 146 is connected between the first output assembly 15a and the first connector 182. It should be noted that... Figure 12 The cleaning equipment shown is different from the cleaning equipment 1 shown. Figure 13 The gas delivery component 13 of the cleaning equipment 1 can also be connected to the first output component 15a, so that the first output component 15a can also output gas, sparkling water or mixed foam.

[0094] See Figure 13In some embodiments, to further enrich the cleaning modes of the cleaning device 1, the control valve assembly 14 further includes a third control valve 145 and a fourth control valve 146, and the cleaning device 1 further includes a third connector 184 and a fourth connector 185. The inlet of the third control valve 145 is connected between the clean water delivery assembly 11 and the first control valve 143 through the third connector 184, and the outlet of the third control valve 145 is connected between the second output assembly 15b and the second connector 183. The inlet of the fourth control valve 146 is connected between the gas delivery assembly 13 and the second control valve 144 through the fourth connector 185, and the outlet of the fourth control valve 146 is connected between the first output assembly 15a and the first connector 182. It should be noted that, with Figure 12 The cleaning equipment shown is different from the cleaning equipment 1 shown. Figure 13 The clean water delivery component 11 of the cleaning equipment 1 can also be connected to the second output component 15b, so that the second output component 15b can also output clean water, mixed liquid, sparkling water or mixed liquid foam. Figure 13 The gas delivery component 13 of the cleaning equipment 1 can also be connected to the first output component 15a, so that the first output component 15a can also output gas, sparkling water or mixed foam.

[0095] Understandably, the third control valve 145 and the fourth control valve 146 can be two shut-off valves, two speed control valves, or two pressure control valves, etc. The third control valve 145 and the fourth control valve 146 can also be two directional control valves, each of which can also be used to connect other pipelines of the cleaning equipment 1; this disclosure does not impose any limitations. The third control valve 145 and the fourth control valve 146 can also be a combination of a shut-off valve and a directional control valve; this disclosure does not impose any limitations.

[0096] See Figures 14 to 16 , Figure 14 This is a schematic diagram of a cleaning device 1 having at least two sets of output components 15, as shown in one embodiment. Figure 15 for Figure 14 A schematic diagram of the internal structure of the cleaning device 1 shown. Figure 16 for Figure 14 The diagram shows another internal structure of the cleaning device 1. The cleaning device 1 also includes a housing assembly 16 and a cleaning brush 17 mounted on the housing assembly 16. 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.

[0097] 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.

[0098] It should be noted that the clean water delivery assembly 11, the cleaning fluid delivery assembly 12, and the gas delivery assembly 13 can be installed inside the housing assembly 16, and the installation position of each delivery assembly inside the housing assembly 16 is not limited to... Figure 15 and Figure 16 The manufacturer can also adjust the installation position of each conveying component in the housing component 16 according to the actual assembly situation to form other layout structures, which are not limited in this disclosure.

[0099] Understandably, the cleaning device 1 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 various input pipes, or it may be composed of mixing devices connected to each input pipe; this disclosure does not impose any limitations.

[0100] Understandably, the cleaning device 1 may also be equipped with a foamer 19 to produce rich and dense foam while conserving cleaning solution. Drive wheels may also be installed on the housing assembly 16 of the cleaning device 1 to reduce the force required for the user to move the cleaning device 1.

[0101] Based on the preceding content, Figure 14 The first output component 15a and the second output component 15b in the cleaning device 1 shown can respectively output various cleaning media such as clean water, cleaning liquid, gas, mixed liquid, sparkling water, cleaning liquid foam, and mixed liquid foam. The cleaning media output by the first output component 15a and the second output component 15b can be the same or different. Furthermore, the first output component 15a and the second output component 15b can be used independently or in combination, allowing them to form multiple cleaning modes, enriching the cleaning modes of the cleaning device 1, thereby improving the cleaning power of the cleaning device 1 and enhancing the user experience.

[0102] In other embodiments, the cleaning device 1 further includes a control device to facilitate switching between various cleaning modes. The control valve assembly 14 is electrically connected to the control device to switch output states.

[0103] 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.

[0104] As an example, see you later. Figure 3 The cleaning device 1 also includes a main unit 20. The control device includes operation buttons installed on the main unit 20 and a controller electrically connected to the operation buttons. The controller is electrically connected to the control valve assembly 14 to switch the output state of the control valve assembly 14 via the operation buttons. Of course, the controller can also be electrically connected to mobile devices such as mobile phones, computers, or tablets, allowing users to switch between various cleaning modes through corresponding application software or applications on mobile devices such as mobile phones, computers, or tablets.
