[0191] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0192] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0193] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0194] In the accompanying drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0195] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0196] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0197] It should be noted that the cleaning equipment in the embodiments of this application may also be called a cleaning device; the floor brush assembly may be called a floor brush device; and the liquid dispensing assembly may be called a liquid dispensing component.

[0198] The cleaning component is also called a roller brush. There are different types of roller brushes. The different types of roller brushes involved in this embodiment can be named first roller brush, second roller brush, first brush body, and second brush body. They can also be called bristle brush, hard tooth brush, or fluff brush according to their structural features.

[0199] Currently, floor scrubbers and other cleaning equipment are typically designed specifically for floor cleaning, offering good cleaning results on hard surfaces like floors. However, with the increasing popularity of carpets in homes, the need for carpet cleaning is becoming more pronounced. Currently, soft surfaces like carpets are usually cleaned using a separate vacuum cleaner. Traditional floor scrubbers cannot effectively clean carpets, forcing users to use the floor scrubber to clean other areas besides the carpet and then switch to a separate vacuum cleaner to clean the carpet. This results in low cleaning efficiency, and the need to use two different cleaning devices takes up a lot of living space, thus affecting the user experience.

[0200] In view of this, and in conjunction with Figures 1 to 9, embodiments of this application provide a control method, apparatus, and cleaning equipment for a cleaning device, which aims to integrate a floor washing function and a vacuuming function into the cleaning equipment, and to control the cleaning equipment to adopt an appropriate cleaning mode for different surfaces to be cleaned.

[0201] The cleaning device in this application embodiment can be a floor scrubber, sweeper, vacuum cleaner, mop, or other cleaning device with cleaning functions. The cleaning device includes a cleaning component, a liquid dispensing assembly, a first scraper, a memory, and a processor. The cleaning device is configured to switch between a first cleaning mode and a second cleaning mode. When the cleaning device is in the first cleaning mode, it performs dry cleaning on at least a first surface to be cleaned; when the cleaning device is in the second cleaning mode, it performs wet cleaning on at least a second surface to be cleaned. It is understood that the cleaning device can also perform dry cleaning on the second surface to be cleaned when in the first cleaning mode, and wet cleaning on the first surface to be cleaned when in the second cleaning mode.

[0202] In some examples, the first surface to be cleaned and the second surface to be cleaned are made of different materials. The first surface to be cleaned can be a flexible cleaning surface with certain fibers, such as a carpet, wool blanket, or floor mat. The second surface to be cleaned can be a relatively smooth cleaning surface, such as a ceramic floor, wooden floor, or marble floor. This application does not limit the specific types of the first and second surfaces to be cleaned.

[0203] In the wet cleaning process of the first surface to be cleaned, the cleaning component is a part used by the cleaning equipment during operation. After startup, the cleaning component rotates and contacts the surface to be cleaned to clean it. The dispensing assembly is used to output cleaning medium to the cleaning component, for example, by spraying cleaning medium onto the cleaning component. The first scraper can form an interference fit with the cleaning component and is used to scrape off cleaning dirt and squeeze cleaning medium from the cleaning component. The memory 1 stores a computer program, and the processor is configured to execute the control method of the cleaning equipment of the present application embodiment through the computer program, or the processor is configured to include a control device of the cleaning equipment of the present application embodiment.

[0204] For example, the cleaning medium can be water or a cleaning solution containing detergent. This application embodiment does not specifically limit the type of cleaning medium. It is understood that the dispensing component and the first scraper can be respectively disposed on the cleaning component, or they can be independently disposed outside the cleaning component. This application embodiment does not specifically limit the placement of the dispensing component and the first scraper.

[0205] In some embodiments, the cleaning device may include at least one of a first brush body and a second brush body. When the cleaning device performs dry cleaning, the cleaning method switches to cleaning the first surface to be cleaned using the first brush body; when the cleaning device performs wet cleaning, the cleaning method switches to cleaning the second surface to be cleaned using the second brush body. Exemplarily, the first brush body may be a brush body adapted to the first surface to be cleaned, such as a bristle brush, and the second brush body may be a brush body adapted to the second surface to be cleaned, such as a soft brush, a cloth, etc.

[0206] In some examples, the cleaning component includes either a first brush body or a second brush body, which can be relatively independent components and interchangeably mounted on the cleaning device. When the cleaning device is performing dry cleaning, the first brush body is mounted on the cleaning device; when switching to wet cleaning, the first brush body is removed and the second brush body is mounted on the cleaning device. This use of relatively independent and interchangeable first and second brush bodies helps reduce the weight of the cleaning device, lowers drive energy consumption, saves energy, and improves the efficiency of movement and cleaning. Furthermore, the relatively independent arrangement of the first and second brush bodies also helps reduce the structural complexity of the cleaning device and facilitates the cleaning and maintenance of the brushes.

[0207] In other examples, the cleaning unit includes a first brush body and a second brush body, which can be selected according to different cleaning modes. For example, the first and second brush bodies can be arranged side by side, front to back, left to right, or top to bottom. When the cleaning device needs to perform dry cleaning, the first brush body is controlled to move to contact the first surface to be cleaned, while the second brush body is spaced apart from the first surface to be cleaned. When the cleaning device needs to perform wet cleaning, the second brush body is controlled to move to contact the second surface to be cleaned, while the first brush body is spaced apart from the second surface to be cleaned. After cleaning, both the first and second brush bodies can be controlled to remain spaced apart from the surface to be cleaned. In this way, the cleaning unit uses an integrated first and second brush body, making the brush switching between dry and wet cleaning more convenient and faster, with higher switching efficiency, and also helping to improve the safety of brush switching.

[0208] In some other examples, the cleaning component includes a first brush body and a second brush body, which can be integrated into one unit. For instance, the cleaning component can be a rotatable roller brush with a surface covered with a soft brush. The soft brush has multiple through-holes, each containing retractable stiff bristles. When dry cleaning is required, the stiff bristles extend out of the through-holes to form the first brush body, cleaning the first surface to be cleaned. When wet cleaning is required, the stiff bristles retract into the through-holes to form the second brush body, cleaning the second surface to be cleaned, thus switching between the first and second brush bodies. This integrated design of the first and second brush bodies simplifies the component's structure and reduces its weight, improving both movement and cleaning efficiency. Furthermore, it makes switching between dry and wet cleaning methods more convenient, efficient, and safer.

[0209] Through the above technical solution, the cleaning equipment is configured to switch between two cleaning modes. When the cleaning equipment is in the first cleaning mode, it can perform dry cleaning on at least the first surface to be cleaned. When the cleaning equipment is in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the two cleaning modes integrated by the cleaning equipment can be flexibly changed according to the needs to adapt to the surface to be cleaned. Thus, when dealing with different types of stains or cleaning surfaces with different characteristics, the most suitable cleaning method can be flexibly selected, so that the cleaning equipment can have the functions of floor washing and vacuuming, realizing multiple uses in one machine, and achieving efficient and high-quality cleaning results. At the same time, the mode switching is convenient, reliable and quick, with a good user experience.

[0210] In some embodiments, the cleaning device may further include a liquid supply line and a suction line. The liquid supply line is connected to a dispensing assembly and is used to supply cleaning medium to the dispensing assembly. A water pump may be connected to the end of the liquid supply line away from the dispensing assembly, and the water pump is used to pump the cleaning medium into the liquid supply line. The suction line is used to suck up cleaning waste, and a suction assembly may be connected to the end of the suction line away from the cleaning component.

[0211] In some examples, the liquid supply line can also be connected to the suction line to provide cleaning media. This allows the cleaning media to be reused to humidify the cleaned waste sucked into the suction line, effectively preventing dry cleaned waste from being directly sucked into the drive mechanism connected to the suction line, thus avoiding increased wear and reduced lifespan of the drive mechanism. Furthermore, it avoids the problems of residual cleaned waste floating in the suction line, which can lead to difficulty in cleaning, increased maintenance, poor air quality, and reduced suction efficiency.

[0212] It is understood that an atomizing nozzle can be installed at the connection between the liquid supply line and the suction line to atomize the cleaning medium and enhance the humidification effect on the cleaned waste. Various components can be used to atomize the cleaning medium, and this application does not specifically limit this one.

[0213] In some examples, a suction port may be provided at the end of the suction pipe facing the cleaning component. When the cleaning device is in the first cleaning mode, the suction port has a first suction force; when the cleaning device is in the second cleaning mode, the suction port has a second suction force; wherein the first suction force is greater than the second suction force. Thus, the suction force of the suction port differs in different cleaning modes. During dry cleaning, the suction force is greater, allowing for more thorough suction and recovery of dirt from the first surface to be cleaned, thereby more effectively achieving the dust removal function and improving cleaning efficiency and effect. Conversely, during wet cleaning, the suction force is lower, and the cleaning of the second surface to be cleaned mainly relies on the cleaning medium adhering to the cleaning component, thereby reducing energy consumption and saving energy.

[0214] In some embodiments, the cleaning device may further include a drive element and a transmission mechanism. The transmission mechanism is connected to the cleaning element, and the drive element is used to provide power to the cleaning element through the transmission mechanism.

[0215] Please refer to Figures 1 and 2 together. Figure 1 is a schematic diagram of the connection of the first brush body in the cleaning device provided in the embodiment of this application, and Figure 2 is a schematic diagram of the connection of the second brush body in the cleaning device provided in the embodiment of this application.

[0216] In some examples, the drive element is used to provide a single rotational speed, such as a constant-speed motor. The transmission mechanism includes a first output shaft 30 and a second output shaft 40 driven by the drive element. A first brush body 10 is configured to be driven by the first output shaft 30, and a second brush body 20 is configured to be driven by the second output shaft 40. Furthermore, the transmission mechanism may also include a planetary gearbox, through which the drive element is driven by the first output shaft 30 and the second output shaft 40 to drive the first output shaft 30 and the second output shaft 40 to rotate synchronously. The first output shaft 30 is configured to drive the first brush body 10 to output a first rotational speed, and the second output shaft 40 is configured to drive the second brush body 20 to output a second rotational speed, the first rotational speed being different from the second rotational speed.

[0217] For example, the second output shaft 40 can be configured as a hollow structure, with the first output shaft 30 extending through the second output shaft 40 along the axial direction X, where the axial direction X is parallel to the axis of the first output shaft 30 in this embodiment. This provides the drive unit with strong versatility, and the dual-shaft arrangement simplifies the internal structure of the cleaning equipment while meeting different output speed requirements, saving internal space and facilitating further reduction in the size of the cleaning equipment. This contributes to the further integration and lightweighting of the cleaning equipment.

[0218] It is understood that the drive unit can also be connected to the first output shaft 30 and the second output shaft 40 by other transmission methods so that the first output shaft 30 and the second output shaft 40 can output different speeds respectively. The embodiments of this application do not specifically limit the transmission method and the structure of the planetary gearbox.

[0219] It is also understood that, in addition to the synchronous rotation of the first output shaft 30 and the second output shaft 40, one of the first output shaft 30 and the second output shaft 40 corresponding to the currently installed brush body can be controlled to rotate while the other does not rotate, depending on the currently installed brush body. This application embodiment does not specifically limit this.

[0220] Exemplarily, the transmission mechanism may further include a first transmission part 50 and a second transmission part 60. The first output shaft 30 can be connected to the first brush body 10 via the first transmission part 50, and the second output shaft 40 can be connected to the second brush body 20 via the second transmission part 60. The first transmission part 50 and the second transmission part 60 may be respectively disposed on the first brush body 10 and the second brush body 20, or respectively disposed on the first output shaft 30 and the second output shaft 40. The embodiments of this application do not specifically limit the placement of the first transmission part 50 and the second transmission part 60.

[0221] As another example, the transmission mechanism may further include a third transmission unit, a clutch, and an elastic element. The clutch and elastic element engage with the first output shaft 30 and the second output shaft 40 respectively depending on their respective states. For example, when the second brush body 20 is installed, the elastic element is compressed, the clutch is engaged, and the third transmission unit and the second output shaft 40 engage. When the first brush body 10 is installed, the elastic element is released, the clutch disengages, and the third transmission unit and the first output shaft 30 engage.

[0222] In other examples, the drive element is used to provide variable speed, for example, it can be a speed-regulating motor. The transmission mechanism may include a third output shaft driven by the drive element, and the first brush body 10 and the second brush body 20 are configured to be interchangeably driven by the third output shaft. The drive element is configured to drive the first brush body 10 to output a first speed via the third output shaft, and to drive the second brush body 20 to output a second speed via the third output shaft, the first speed and the second speed being different. In this way, the drive element can output different power through a single shaft, thereby further simplifying the internal structure of the cleaning equipment, reducing the weight of the cleaning equipment, and improving cleaning efficiency.

[0223] In some examples, the first rotational speed is greater than the second rotational speed. For example, the first rotational speed n1 can satisfy: 2300 rpm / min ≤ n1 ≤ 2600 rpm / min, that is, the value of n1 can be any one or any combination of two of the following: 2300, 2310, 2320, 2330, 2340, 2350, 2360, 2370, 2380, 2390, 2400, 2410, 2420, 2430, 2440, 2450, 2460, 2470, 2480, 2490, 2500, 2510, 2520, 2530, 2540, 2550, 2560, 2570, 2580, 2590, 2593, and 2600. The second rotational speed n2 can satisfy the following condition: 480 rpm / min ≤ n2 ≤ 600 rpm / min. That is, the value of n2 can be any one or any combination of two of the following: 480, 485, 490, 495, 500, 505, 510, 515, 520, 525, 530, 535, 540, 545, 550, 555, 560, 563, 565, 570, 575, 580, 585, 590, 595, and 600. Preferably, the first rotational speed n1 can be 2490 rpm / min, and the second rotational speed n2 can be 540 rpm / min. This provides good adaptability to various cleaning surfaces and compatibility with various driving components, making implementation relatively convenient.

[0224] Through the above technical solution, the rotation speed of the cleaning component varies in different cleaning modes. In dry cleaning, the initial rotation speed is faster, allowing the cleaning component to quickly contact the first surface to be cleaned, thoroughly agitating and shaking off the dirt, thus more effectively collecting the cleaning debris and improving cleaning efficiency. Conversely, in wet cleaning, the second rotation speed is slower, allowing the cleaning component to fully contact the second surface to be cleaned. The cleaning medium adhering to the cleaning component can effectively act on the second surface, breaking down the dirt and improving the cleaning effect. Furthermore, in dry cleaning, the faster initial rotation speed results in a correspondingly stronger suction force at the suction port, allowing for more thorough suction and recovery of the dirt from the first surface, thus more effectively achieving the vacuuming function and improving cleaning efficiency and effect. In wet cleaning, the slower second rotation speed results in a correspondingly weaker suction force at the suction port, thereby reducing energy consumption and saving energy.

[0225] In some embodiments, the cleaning device may further include a sensing component configured to trigger a corresponding first state signal based on the state of the cleaning element.

[0226] In some examples, the sensing component may include a first suction member and a Hall sensor connected to the first suction member. The first suction member has a first suction state and a first release state. The Hall sensor is configured to generate a first state signal based on either the first suction state or the first release state. When the first suction member is in the first suction state, the first state signal indicates that the state of the first brush body is a target state. The target state can be used to characterize a state where the brush body 10 is installed. For example, after the first brush body 10 is installed, the first suction member is in the first suction state. At this time, the Hall sensor generates a first state signal to indicate that the first brush body 10 is installed and the cleaning device can enter a first cleaning mode. When the first brush body 10 is not installed, the first suction member can switch to a first release state. At this time, the Hall sensor generates a first state signal to indicate that the first brush body 10 is not installed and the cleaning device cannot enter the first cleaning mode.

[0227] Through the above technical solution, the first suction component cooperates with the Hall sensor, and the state of the first brush body 10 is reflected by the two states of the first suction component. One sensing component can realize the monitoring of multiple states. The structure is relatively simple and ingenious, which is conducive to conveniently indicating different states of the brush body, and the identification is relatively simple and reliable.

[0228] In some examples, the first attraction member may include a first magnetic attraction member and a first magnet. The first magnetic attraction member may be disposed on the body of the cleaning device, and the first magnet may be disposed on the first brush body 10, so that the first magnet and the first magnetic attraction member attract each other after the first brush body 10 is installed, thereby making the first attraction member a first attraction state, and the first magnet and the first magnetic attraction member separate after the first brush body 10 is disassembled, thereby making the first attraction member a first release state.

[0229] Correspondingly, if the first state signal is not present, the system can switch to the second cleaning mode.

[0230] In other examples, the sensing component can also be configured to trigger a corresponding second state signal based on the state of the cleaning element. The sensing component may also include a second suction element connected to a Hall sensor. The second suction element has a second suction state and a second release state, and the Hall sensor is configured to generate a second state signal based on either the second suction state or the second release state. When the second suction element is in the second suction state, the second state signal indicates that the state of the second brush 20 is the target state. For example, after the second brush 20 is installed in place, the second suction element is in the second suction state, at which time the Hall sensor generates a second state signal to indicate that the second brush 20 is installed in place and the cleaning device can enter the second cleaning mode; when the second brush 20 is not installed in place, the second suction element can switch to the second release state, at which time the Hall sensor generates a second state signal to indicate that the second brush 20 is not installed in place and the cleaning device cannot enter the second cleaning mode.

[0231] In some examples, the second attraction member may include a second magnetic attraction member and a second magnet. The second magnetic attraction member may be disposed on the body of the cleaning device, and the second magnet may be disposed on the second brush body 20 so that the second magnet and the second magnetic attraction member attract each other after the second brush body 20 is installed, thereby placing the second attraction member in a second attraction state, and the second magnet and the second magnetic attraction member separate after the second brush body 20 is disassembled, thereby placing the second attraction member in a second release state.

[0232] It should be noted that the first magnetic component and the second magnetic component can be the same magnetic component.

[0233] With the above technical solution, both the first and second suction components cooperate with the Hall sensor. The state of the first brush body 10 is reflected by the two states of the first suction component, and the state of the second brush body 20 is reflected by the two states of the second suction component. One sensing component can realize the monitoring of multiple states. The structure is relatively simple and ingenious, which is conducive to conveniently indicating the different states of different brush bodies, and the identification is relatively simple and reliable.

[0234] In other examples, the sensing component may also adopt other sensing structures, and this application embodiment does not specifically limit this.

[0235] In some embodiments, the cleaning device may further include a second scraper. The second scraper may engage with the surface to be cleaned and is configured to apply friction to the surface to remove dirt or cleaning media residue from the surface to be cleaned.

[0236] In actual implementation, the cleaning equipment may also include other components, such as handles, body components, water tanks, etc. This embodiment will not list all the components included in the cleaning equipment.

[0237] By adopting the above technical solution, this cleaning equipment integrates floor washing and vacuuming functions, and can switch between two cleaning modes. In the first cleaning mode, the equipment can perform dry cleaning on at least the first surface to be cleaned, and in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the cleaning mode of the equipment can be flexibly changed according to needs to adapt to the surface to be cleaned. Thus, when dealing with different types of stains or cleaning surfaces with different characteristics, the most suitable cleaning method can be flexibly selected to achieve efficient and high-quality cleaning results. At the same time, the mode switching is convenient, reliable, and quick. This cleaning equipment can provide a comfortable and convenient cleaning experience, and has both wet and dry cleaning functions, making it suitable for a wide range of scenarios and providing a good user experience.

[0238] The control method of the cleaning equipment provided in this application will be described in detail below.

[0239] Please refer to Figure 3, which is a schematic flowchart of a control method for a cleaning device provided in an embodiment of this application. This embodiment uses the method applied to a cleaning device as an example, such as the main control board of the cleaning device. In other embodiments, it can also be executed by other devices communicatively connected to the cleaning device, such as remotely controlling the cleaning device via a mobile phone, computer, tablet, etc. This embodiment does not limit the implementation methods of other devices or the execution subject of each embodiment. The control method for the cleaning device includes at least the following steps:

[0240] Step 301: In response to the switching trigger command of the first cleaning mode, control the first scraper to move in the first direction so that the first scraper and the cleaning component are spaced apart.

[0241] The switching trigger command for the first cleaning mode can be configured to instruct the cleaning device to switch from the second cleaning mode to the first cleaning mode, that is, to instruct the cleaning device to perform dry cleaning.

[0242] In some embodiments, the method for generating the switching trigger instruction for the first cleaning mode includes:

[0243] In response to the installation of the first brush body, a switching trigger command for the first cleaning mode is generated. This means the switching trigger command for the first cleaning mode can be automatically generated in response to the installation of the first brush body, thereby improving mode switching efficiency, simplifying manual operation, enhancing the user experience, and making mode switching more efficient, accurate, and reliable.

[0244] In some examples, the cleaning device includes sensing components, so the method for generating a switching trigger command for the first cleaning mode in response to the installation action of the first brush body can specifically include the following steps:

[0245] Obtain the first state signal of the sensing component.

[0246] If the first status signal indicates that the first brush body is in the target state, a switching trigger command for the first cleaning mode is generated.

[0247] It is understood that, correspondingly, a second state signal from the sensing component can also be acquired. If the second state signal indicates that the state of the second brush body is the target state, a switching trigger command for the second cleaning mode is generated. See the relevant description in the subsequent embodiments for details.

[0248] By adopting the above technical solution, the sensor component can sense the information of the brush body in place, thereby quickly confirming that the brush body is in the target state. The identification is relatively simple and reliable. Moreover, the installation status of the roller brush can be detected in real time and timely feedback can be provided, thereby ensuring that the roller brush is correctly installed and meets the requirements, and quickly switching the cleaning mode.

[0249] In other embodiments, the method for generating the switching trigger command for the first cleaning mode includes:

[0250] In response to the user's mode switching operation, a switching trigger command for the first cleaning mode is generated. This means that the first cleaning mode switching trigger command can be generated in response to the user's active operation after the first brush body is installed, enabling a more timely and accurate response to the user's dry cleaning needs and better aligning with user preferences, thereby enhancing the user's product experience.

[0251] In some examples, a user's mode switching operation may include a click or touch operation on a mode switching button. This mode switching button can be a physical button or a virtual button implemented via a touchscreen display; this embodiment does not limit the implementation method of the mode switching button.

[0252] By adopting the above technical solution, in response to the switching trigger command of the first cleaning mode, the cleaning equipment can control the first scraper and the cleaning component to be spaced apart, thereby avoiding interference of the first scraper with the movement path of the cleaning component during the cleaning process. In the dry cleaning mode, not only can the first scraper not generate additional friction on the cleaning component, thus avoiding increasing the load on the drive component and affecting its lifespan, but it can also avoid affecting the dry cleaning effect of the cleaning component on the first surface to be cleaned, so that the cleaning component can clean more effectively and improve cleaning efficiency.

[0253] In some embodiments, the first scraper blade can be controlled to move in a first direction by the following steps:

[0254] Control the first scraper to rotate and / or move in the first direction.

[0255] For example, when the cleaning equipment switches to the first cleaning mode, the first scraper can be controlled to rotate only in the first direction to move away from the cleaning component; or the first scraper can be controlled to move only in the first direction to move away from the cleaning component; or the first scraper can be controlled to move and rotate simultaneously in the first direction to move away from the cleaning component. In this way, the first scraper can be controlled to move away from the cleaning component in multiple ways, thus achieving a more flexible approach and better adapting to different structures of the cleaning equipment.

[0256] Step 302: Control the liquid distribution component to stop outputting cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned.

[0257] In the first cleaning mode, the cleaning component outputs a first rotational speed n1.

[0258] For example, the first rotational speed n1 can satisfy: 2300rpm / min≤n1≤2600rpm / min, as can be seen in the description of the foregoing embodiments, which will not be repeated here.

[0259] In some embodiments, step 302 can be implemented through the following steps:

[0260] Control the liquid supply line to stop outputting cleaning medium to the liquid distribution assembly.

[0261] The system controls the supply pipeline to provide cleaning medium to the suction pipeline, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned.

[0262] By adopting the above technical solution, the liquid supply pipeline stops outputting cleaning medium to the liquid distribution component while simultaneously supplying cleaning medium to the suction pipeline. This not only prevents the liquid distribution component from outputting cleaning medium to the cleaning components, thus enabling the cleaning equipment to perform dry cleaning on the first surface to be cleaned, but also humidifies the cleaning contaminants sucked into the suction pipeline. This effectively prevents dry cleaning contaminants from being directly sucked into the drive components connected to the suction pipeline, thereby increasing wear on the drive components and affecting their service life. Furthermore, it avoids the problems of residual cleaning contaminants floating in the suction pipeline, which can lead to difficulty in cleaning, increased maintenance difficulty, impact on air quality, and reduced dust collection efficiency.

[0263] In some examples, the supply line can be controlled to provide atomized cleaning media into the suction line. This atomized cleaning media allows for more even wetting of the dirt, making it easier to absorb and remove. Consequently, the dirt sucked in during dry cleaning is more easily and effectively collected and processed, improving the efficiency of dry cleaning. Furthermore, it saves on the consumption of cleaning media, allowing it to be supplied more effectively to scenarios requiring wet cleaning.

[0264] Furthermore, in some embodiments, step 302 may also include:

[0265] Control the movement of the dispensing assembly to keep it away from the cleaning component.

[0266] In some scenarios, the distance between the dispensing component and the cleaning component may be small. Therefore, when the cleaning component performs its cleaning action, the dispensing component may interfere with its path. Thus, during dry cleaning, controlling the dispensing component to move away from the cleaning component allows it to avoid the component's movement path, further reducing the risk of additional friction on the cleaning component, which could increase the load on the drive component and affect its lifespan. It should be noted that controlling the movement of the dispensing component can be performed simultaneously with stopping the dispensing component from outputting cleaning medium to the cleaning component, or it can be done sequentially. This application does not specify a particular order for controlling the components.

[0267] By adopting the above technical solution, the cleaning equipment is configured to switch between two cleaning modes. In the first cleaning mode, the cleaning equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the two integrated cleaning modes can flexibly change according to needs to adapt to the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The cleaning equipment includes a cleaning component, a liquid dispensing assembly, and a first scraper. In response to the switching trigger command of the first cleaning mode, the cleaning equipment can control the spacing between the first scraper and the cleaning component. This avoids interference between the first scraper and the movement path of the cleaning component during cleaning, preventing additional friction on the cleaning component and thus avoiding increased load on the drive component, which could affect its lifespan. It also prevents interference with the cleaning component's contact with the first surface to be cleaned. The cleaning effect allows the cleaning components to clean more effectively, improving cleaning efficiency. By controlling the dispensing component to stop outputting cleaning media to the cleaning components, the cleaning equipment can achieve a dry cleaning effect on the first surface to be cleaned. This not only saves the amount of cleaning media used but also avoids the situation where the first surface to be cleaned is not easy to dry after it becomes wet, which could lead to bacterial growth or odors that affect the user experience. It also prevents cleaning media residue from remaining on the first surface to be cleaned, thus improving cleaning quality. At the same time, in the first cleaning mode, the cleaning components can output a first rotation speed to match the first surface to be cleaned, which can better meet the cleaning needs of the first surface to be cleaned and more precisely control the cleaning action and pressure, thereby improving cleaning quality, reducing residue, and protecting the integrity of the first surface to be cleaned. Therefore, it can better adapt to the cleaning tasks and application scenarios of the first surface to be cleaned. This cleaning equipment can provide a more comfortable and convenient cleaning experience, combining the functions of wet and dry cleaning, with a wide range of applicable scenarios and a better user experience.

[0268] Please refer to Figure 4, which is a schematic flowchart illustrating a control method for a cleaning device according to an embodiment of this application. In some embodiments, the control method for a cleaning device provided in this application may include the following steps in addition to the aforementioned steps 301 and 302:

[0269] Step 401: Control the movement of the second scraper so that the second scraper and the first surface to be cleaned are spaced apart.

[0270] For example, the second scraper can be controlled to move and / or rotate in a third direction to move away from the first surface to be cleaned. Specifically, the second scraper can be moved to a position that completely avoids fibers (such as carpet fibers) protruding from the first surface to be cleaned, thus maximizing the avoidance of the first surface to be cleaned; or the second scraper can be moved to a position where the fibers protruding from the first surface to be cleaned interfere to some extent, as long as it does not completely adhere to the first surface to be cleaned. This application embodiment does not specifically limit the avoidance position of the second scraper. In this way, during dry cleaning, since the first surface to be cleaned is relatively dry and the friction is relatively high, controlling the retraction of the second scraper to create a gap between it and the first surface to be cleaned can reduce or even avoid the friction between the second scraper and the first surface to be cleaned during the cleaning process, reduce the moving load of the cleaning equipment, improve cleaning efficiency, and also better protect the second scraper from the friction of the first surface to be cleaned, extending the service life of the second scraper.

[0271] It is understood that the steps 301, including controlling the first scraper to move in the first direction, 302, including controlling the dispensing component to stop outputting cleaning medium to the cleaning component, and 401, including controlling the second scraper to move, are all executed in response to the switching trigger command of the first cleaning mode. They can be executed sequentially or simultaneously. This application embodiment does not specifically limit the control order of the first scraper, the dispensing component, and the second scraper.

[0272] Step 402: In response to the switching trigger command of the second cleaning mode, control the first scraper to move in the second direction so that the first scraper comes into contact with the cleaning component.

[0273] The first direction and the second direction are opposite.

[0274] Specifically, the switching trigger command for the second cleaning mode can be configured to instruct the cleaning device to switch from the first cleaning mode to the second cleaning mode, that is, to instruct the cleaning device to perform wet cleaning.

[0275] In some embodiments, the method for generating the switching trigger instruction for the second cleaning mode includes:

[0276] In response to the installation of the second brush body, a switching trigger command for the second cleaning mode is generated. This means the switching trigger command for the second cleaning mode can be automatically generated in response to the installation of the second brush body, thereby improving mode switching efficiency, simplifying manual operation, enhancing the user experience, and making mode switching more efficient, accurate, and reliable.

[0277] In some examples, the cleaning device includes sensing components, so the method for generating a switching trigger command for the second cleaning mode in response to the installation action of the second brush body can specifically include the following steps:

[0278] Acquire the second state signal of the sensing component.

[0279] If the second status signal indicates that the second brush body is in the target state, a switching trigger command for the second cleaning mode is generated.

[0280] By adopting the above technical solution, the sensor component can sense the information of the brush body in place, thereby quickly confirming that the brush body is in the target state. The identification is relatively simple and reliable. Moreover, the installation status of the roller brush can be detected in real time and timely feedback can be provided, thereby ensuring that the roller brush is correctly installed and meets the requirements, and quickly switching the cleaning mode.

[0281] In other embodiments, the method for generating the switching trigger command for the second cleaning mode includes:

[0282] In response to the user's mode switching operation, a switching trigger command for the second cleaning mode is generated.

[0283] Specifically, the user's mode switching operation can be found in the description of the aforementioned embodiments, and will not be repeated here.

[0284] By adopting the above technical solution, in response to the switching trigger command of the second cleaning mode, the cleaning equipment can control the first scraper to abut against the cleaning component, so that the first scraper can form an interference fit with the cleaning component during the cleaning process, and is used to scrape off the cleaning dirt on the cleaning component and squeeze the cleaning medium on the cleaning component, so that the cleaning component can more effectively clean the second surface to be cleaned and improve the cleaning effect.

[0285] In some embodiments, the first scraper blade can be controlled to move in the second direction by the following steps:

[0286] Control the first scraper to rotate and / or move in the second direction.

[0287] For example, when the cleaning equipment switches to the second cleaning mode, the first scraper can be controlled to rotate only in the second direction to approach the cleaning object; or the first scraper can be controlled to move only in the second direction to approach the cleaning object; or the first scraper can be controlled to move and rotate simultaneously in the second direction to approach the cleaning object. In this way, the first scraper can be controlled to approach the cleaning object in multiple ways, thus achieving a more flexible approach and better adapting to different structures of the cleaning equipment.

[0288] Step 403: Control the liquid separation component to start and output the cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform wet cleaning on the second surface to be cleaned.

[0289] In the second cleaning mode, the cleaning component outputs a second rotational speed n2, where the first rotational speed n1 is greater than the second rotational speed n2.

[0290] For example, the second rotational speed n2 can satisfy: 480rpm / min≤n2≤600rpm / min, as can be seen in the description of the foregoing embodiments, which will not be repeated here.

[0291] In some embodiments, step 403 can be implemented through the following steps:

[0292] Control the liquid supply line to stop supplying cleaning medium to the suction line.

[0293] The liquid supply line is activated to output cleaning medium to the liquid distribution assembly, thereby controlling the cleaning equipment to perform wet cleaning on the second surface to be cleaned.

[0294] By adopting the above technical solution, the cleaning equipment can be restored to the floor washing mode, and the second surface to be cleaned can be cleaned with the cleaning medium, which has a better cleaning effect.

[0295] In other embodiments, step 403 can be implemented through the following steps:

[0296] Control the liquid supply line to continue supplying cleaning medium to the suction line.

[0297] The liquid supply line is activated to output cleaning medium to the liquid distribution assembly, thereby controlling the cleaning equipment to perform wet cleaning on the second surface to be cleaned.

[0298] In some examples, the supply line can be controlled to provide atomized cleaning media into the suction line.

[0299] By adopting the above technical solution, the liquid supply pipeline continues to supply cleaning medium to the suction pipeline while simultaneously outputting cleaning medium to the liquid distribution component. This not only enables the cleaning equipment to perform wet cleaning on the second surface to be cleaned, but also simultaneously humidifies the cleaning contaminants sucked into the suction pipeline that have not been fully moistened by the cleaning medium. This effectively prevents dry cleaning contaminants from being directly sucked into the drive components connected to the suction pipeline, thereby increasing wear on the drive components and affecting their service life. In addition, it also avoids the problems of residual cleaning contaminants floating in the suction pipeline, which are difficult to clean, increase maintenance difficulty, affect air quality, and reduce dust collection efficiency.

[0300] In addition, in some embodiments, step 403 may also include the following steps:

[0301] Control the movement of the dispensing assembly to bring it closer to the cleaning component. This allows for a larger cleaning medium output area, enabling more thorough and rapid wetting of the second brush body, thus achieving a more efficient cleaning effect on the second surface to be cleaned.

[0302] It should be noted that controlling the movement of the liquid dispensing component can be performed simultaneously with controlling the start of the liquid dispensing component to output cleaning medium to the cleaning component, or it can be performed sequentially. This application embodiment does not specify the order of control of each component.

[0303] By adopting the above technical solution, in response to the switching trigger command of the second cleaning mode, the cleaning medium is output to the cleaning component by controlling the liquid dispensing component, thereby controlling the cleaning equipment to perform wet cleaning on the second surface to be cleaned, thus improving the cleaning effect of the second surface to be cleaned; the cleaning equipment can control the first scraper to contact the cleaning component, so that when switching to wet cleaning, the first scraper can promptly scrape off the cleaning dirt and squeeze out the cleaning medium on the cleaning component, so that the cleaning dirt can be collected in time, ensuring cleaning quality. In addition, it can also prevent the cleaning dirt from being carried into the cleaning equipment or thrown onto the cleaning surface, thereby further improving the cleaning effect of wet cleaning; in addition, the rotation speed is different in different cleaning modes. The first rotation speed output during dry cleaning is faster, so that the cleaning component can quickly contact the first surface to be cleaned, thereby shaking off the dirt on the first surface to be cleaned, and then more effectively sucking it in and collecting it, improving cleaning efficiency. On the other hand, the second rotation speed output during wet cleaning is slower, so that the cleaning component can fully contact the second surface to be cleaned, and the cleaning medium adhering to the cleaning component can fully act on the second surface to be cleaned, improving the cleaning effect. In addition, the initial rotation speed during dry cleaning is faster, which in turn results in a stronger suction force for the cleaning equipment to draw in the dirt, thereby further improving the cleaning effect of dry cleaning.

[0304] Furthermore, in some embodiments, the control method for the cleaning equipment provided in this application may further include:

[0305] Step 404: Control the movement of the second scraper so that the second scraper comes into contact with the second surface to be cleaned.

[0306] For example, the second scraper can be controlled to move and / or rotate in a third direction to approach the first surface to be cleaned. In this way, since cleaning residue or cleaning media often remains on the second surface during wet cleaning, affecting cleanliness and posing a safety hazard due to slipperiness, controlling the second scraper to contact the second surface allows for the further recovery of residual cleaning residue or cleaning media through the friction of the second scraper against the second surface, thereby improving the cleaning effect of wet cleaning.

[0307] It is understood that the steps 402, including controlling the first scraper to move in the second direction, 403, including controlling the dispensing component to start and output cleaning medium to the cleaning component, and 404, including controlling the second scraper to move, are all executed in response to the switching trigger command of the second cleaning mode. They can be executed sequentially or simultaneously. This application embodiment does not specifically limit the control order of the first scraper, the dispensing component, and the second scraper.

[0308] Please refer to Figure 5, which is a schematic flowchart of another control method for cleaning equipment provided in an embodiment of this application. The control method for cleaning equipment includes at least the following steps:

[0309] Step 501: Obtain the switching trigger command for the first cleaning mode.

[0310] Step 502: In response to the switching trigger command of the first cleaning mode, control the liquid dispensing component to stop outputting cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned.

[0311] In the first cleaning mode, the cleaning component outputs a first rotational speed.

[0312] By adopting the above technical solution, the cleaning equipment is configured to switch between two cleaning modes. In the first cleaning mode, the cleaning equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the two integrated cleaning modes of the cleaning equipment can flexibly change according to needs, switching to the cleaning mode suitable for the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The cleaning equipment includes a cleaning component and a dispensing assembly. In response to the switching trigger command of the first cleaning mode, the cleaning equipment can control the dispensing assembly to stop outputting cleaning medium to the cleaning component, thereby controlling the cleaning equipment to... This device achieves dry cleaning of the first surface to be cleaned, saving on cleaning media usage and preventing the surface from becoming damp and difficult to dry, thus improving user experience. It also avoids cleaning media residue on the surface, enhancing cleaning quality. In the first cleaning mode, the device controls the cleaning component to output a specific rotation speed to match the surface, better meeting its cleaning needs and allowing for more precise control of cleaning actions and pressure. This improves cleaning quality, reduces residue, and protects the integrity of the surface. Therefore, it is better suited for cleaning tasks and application scenarios, providing a comfortable and convenient cleaning experience. Combining wet and dry cleaning functions, it is widely applicable and offers a superior user experience.

[0313] In some embodiments, the control method further includes:

[0314] The first scraper is controlled to move in a first direction so that the first scraper and the cleaning element are spaced apart.

[0315] By using the above technical solution, in the case of dry cleaning, the interference of the first scraper on the movement path of the cleaning component can be avoided. This not only avoids generating additional friction on the cleaning component, thereby increasing the load on the drive component and affecting its lifespan, but also avoids affecting the cleaning effect of the cleaning component on the first surface to be cleaned, allowing the cleaning component to clean more effectively and improving cleaning efficiency.

[0316] In some embodiments, step 502 is implemented in the following manner:

[0317] Control the liquid supply line to stop supplying cleaning medium to the liquid distribution assembly;

[0318] The system controls the supply pipeline to provide cleaning medium to the suction pipeline, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned.

[0319] By adopting the above technical solution, the liquid supply pipeline not only stops outputting cleaning medium to the liquid distribution component, but also provides cleaning medium to the suction pipeline. This not only enables the cleaning equipment to perform dry cleaning on the first surface to be cleaned, but also humidifies the cleaning contaminants sucked into the suction pipeline. This effectively prevents dry cleaning contaminants from being directly sucked into the drive components connected to the suction pipeline, thereby increasing wear on the drive components and affecting their service life. Furthermore, it avoids the problems of residual cleaning contaminants floating in the suction pipeline, which can lead to difficulty in cleaning, increased maintenance difficulty, impact on air quality, and reduced dust collection efficiency.

[0320] In some embodiments, controlling the supply line to provide cleaning medium to the suction line, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned, includes:

[0321] Control the supply line to provide atomized cleaning medium into the suction line.

[0322] By adopting the above technical solution, the liquid supply pipeline provides atomized cleaning medium to the suction pipeline, which can more evenly wet the cleaning dirt, making it easier to adsorb and remove. This makes it easier to effectively collect and treat the cleaning dirt sucked in during dry cleaning, improving the effect of dry cleaning. In addition, it can save the consumption of cleaning medium, allowing it to be supplied more effectively to the scene that needs cleaning.

[0323] In some embodiments, the method for generating the switching trigger instruction for the first cleaning mode includes:

[0324] In response to the installation action of the first brush body, a switching trigger command for the first cleaning mode is generated.

[0325] By adopting the above technical solution, the switching trigger command for the first cleaning mode can be automatically generated in response to the installation action of the first brush body, thereby improving the efficiency of mode switching, simplifying manual operation, and enhancing the user experience.

[0326] In some embodiments, the cleaning device includes a sensing component, then in response to the installation action of the first brush body, a switching trigger command for a first cleaning mode is generated, including:

[0327] Acquire the first state signal of the sensing component;

[0328] If the first status signal indicates that the first brush body is in the target state, a switching trigger command for the first cleaning mode is generated.

[0329] By adopting the above technical solution, the sensor component can sense the information of the brush body in place, thereby quickly confirming that the brush body is in the target state. The identification is relatively simple and reliable, and the installation status of the roller brush can be detected in real time and timely feedback can be provided, thereby ensuring that the roller brush is correctly installed and meets the requirements.

[0330] In some embodiments, the control method further includes:

[0331] In response to the switching trigger command of the second cleaning mode, the liquid dispensing component is controlled to start outputting cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform wet cleaning on the second surface to be cleaned; wherein, in the second cleaning mode, the cleaning component outputs a second rotation speed, and the first rotation speed is greater than the second rotation speed.

[0332] By adopting the above technical solution, in response to the switching trigger command of the second cleaning mode, the cleaning medium is output to the cleaning component by controlling the liquid dispensing component, thereby controlling the cleaning equipment to switch to wet cleaning of the second surface to be cleaned, thus improving the cleaning effect of the second surface to be cleaned. Furthermore, the rotation speed varies in different cleaning modes. During dry cleaning, the initial rotation speed is faster, allowing the cleaning component to quickly contact the first surface to be cleaned, effectively shaking off dirt and collecting it more efficiently, thus improving cleaning efficiency. Conversely, during wet cleaning, the second rotation speed is slower, allowing the cleaning component to fully contact the second surface to be cleaned, ensuring the cleaning medium adhering to the component can effectively act on the second surface, improving the cleaning effect. In addition, the faster initial rotation speed during dry cleaning results in a stronger suction force for the cleaning equipment, further enhancing the cleaning effect of dry cleaning.

[0333] In some embodiments, the control method further includes:

[0334] In response to the switching trigger command of the second cleaning mode, the first scraper is controlled to move in the second direction so that the first scraper comes into contact with the cleaning component; wherein the first direction and the second direction are opposite.

[0335] By adopting the above technical solution, in the second cleaning mode, the cleaning equipment can control the first scraper to extend and contact the cleaning part. Thus, when switching to wet cleaning, the first scraper can promptly scrape off the cleaning dirt on the cleaning part and squeeze out the cleaning medium on the cleaning part, so that the cleaning dirt can be collected in time to ensure the cleaning quality. In addition, it can also prevent the cleaning dirt from being brought into the cleaning equipment or thrown onto the cleaning surface, thereby further improving the cleaning effect of wet cleaning.

[0336] In some embodiments, controlling the dispensing assembly to stop discharging cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned, further includes:

[0337] Control the movement of the dispensing assembly to keep it away from the cleaning component.

[0338] By adopting the above technical solution, the liquid distribution component is kept away from the cleaning component during dry cleaning, so that the liquid distribution component can avoid the movement path of the cleaning component in time, thereby avoiding additional friction on the cleaning component, which would increase the load on the drive component and affect its life.

[0339] In some embodiments, the control method further includes:

[0340] Control the movement of the second scraper so that the second scraper and the first surface to be cleaned are spaced apart.

[0341] By adopting the above technical solution, the second scraper can be controlled to retract during dry cleaning, thus creating a gap between it and the first surface to be cleaned. This reduces or even eliminates the friction between the second scraper and the first surface to be cleaned during the cleaning process, reducing the moving load on the cleaning equipment, improving cleaning efficiency, and better protecting the second scraper from friction from the first surface to be cleaned, thereby extending the service life of the second scraper.

[0342] In some embodiments, controlling the first scraper to move in a first direction includes:

[0343] Control the first scraper to rotate and / or move in the first direction.

[0344] By adopting the above technical solution, the first scraper can be controlled to move away from the cleaning component in multiple ways, thus achieving a more flexible approach and better adapting to different structures of cleaning equipment.

[0345] It should be noted that the implementation of the embodiments in this application can refer to the foregoing embodiments, and the relevant details will not be repeated here.

[0346] Please refer to Figure 6, which is a schematic flowchart of another control method for cleaning equipment provided in this application embodiment. The control method for cleaning equipment includes at least the following steps:

[0347] Step 601: In response to the switching trigger command of the first cleaning mode, control the first scraper to move in the first direction so that the first scraper and the cleaning component are spaced apart.

[0348] Step 602: Control the liquid distribution component to stop outputting cleaning medium to the cleaning component, and control the liquid distribution component to provide cleaning medium to the suction pipe, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned.

[0349] In the first cleaning mode, the cleaning component outputs a first rotational speed.

[0350] By adopting the above technical solution, the cleaning equipment is configured to switch between two cleaning modes. In the first cleaning mode, the equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the two integrated cleaning modes can flexibly change according to needs to adapt to the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The cleaning equipment includes a cleaning component, a dispensing assembly, a first scraper, and a suction pipe. In response to the switching trigger command of the first cleaning mode, the cleaning equipment can control the first scraper and the cleaning component to be spaced apart, thereby avoiding interference between the first scraper and the movement path of the cleaning component during cleaning. This not only avoids generating additional friction on the cleaning component, thus preventing increased load on the drive component and affecting its lifespan, but also avoids affecting the cleaning effect of the cleaning component on the first surface to be cleaned, allowing the cleaning component to clean more effectively and improving cleaning efficiency. By controlling the dispensing assembly to stop outputting cleaning fluid to the cleaning component... The cleaning device, by controlling the cleaning medium, can achieve dry cleaning of the first surface to be cleaned. This not only saves on the amount of cleaning medium used but also avoids the problem of the first surface being difficult to dry after it becomes damp, thus preventing bacterial growth and affecting the user experience. It also prevents cleaning medium residue from remaining on the first surface, thereby improving cleaning quality. Furthermore, in the first cleaning mode, the cleaning device controls the cleaning component to output a specific rotational speed to match the first surface to be cleaned, better meeting its cleaning needs and allowing for more precise control of cleaning actions and pressure, thereby improving cleaning quality and reducing residue. This cleaning device not only dry-cleans the first surface to be cleaned but also humidifies the dirt sucked into the suction pipe, preventing dry dirt from being directly sucked into the drive unit connected to the suction pipe, thus avoiding increased wear and lifespan of the drive unit. It also avoids the problems of residual dirt floating in the suction pipe, which can lead to difficult cleaning, increased maintenance, air quality issues, and reduced suction efficiency. Therefore, this cleaning device is better suited to the cleaning tasks and application scenarios of the first surface to be cleaned. It provides a comfortable and convenient cleaning experience, combining floor washing and dry vacuuming functions, making it suitable for a wide range of scenarios and offering a good user experience.

[0351] It should be noted that another control method in this application embodiment may also include the content described in steps 401 to 404 above. The implementation details of the control method in this application embodiment can be referred to in conjunction with the implementation details of steps 301 to 302, 401 to 404, and 501 to 502 in the aforementioned embodiments. The relevant details will not be repeated here.

[0352] Please refer to Figure 7, which is a schematic diagram of the structure of a control device for a cleaning equipment provided in an embodiment of this application. This embodiment of the application uses the processor of the cleaning equipment in this application as an example for illustrative purposes. The device includes at least the following two modules: a first scraper drive module 701 and a first control module 702.

[0353] The first scraper drive module 701 is used to control the first scraper to move in the first direction in response to the switching trigger command of the first cleaning mode, so that the first scraper and the cleaning component are spaced apart from each other.

[0354] The first control module 702 is used to control the liquid distribution component to stop outputting cleaning medium to the cleaning component, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned; wherein, in the first cleaning mode, the cleaning component outputs a first rotation speed.

[0355] By adopting the above technical solution, the control device of the cleaning equipment can switch between two cleaning modes. In the first cleaning mode, the cleaning equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the cleaning mode can be flexibly adjusted according to needs to adapt to the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The first scraper drive module 701, responding to the switching trigger command of the first cleaning mode, can control the spacing between the first scraper and the cleaning component. This avoids interference between the first scraper and the movement path of the cleaning component during cleaning, preventing additional friction on the cleaning component, thus avoiding increased load on the drive component and affecting its lifespan. It also avoids affecting the cleaning effect of the cleaning component on the first surface to be cleaned. This allows the cleaning components to clean more effectively, improving cleaning efficiency. The first control module 702 can control the dispensing component to stop outputting cleaning medium to the cleaning components, thereby enabling the cleaning equipment to achieve dry cleaning of the first surface to be cleaned. This not only saves the amount of cleaning medium used but also avoids the situation where the first surface to be cleaned is not easy to dry after it becomes wet, thus affecting the user experience. It also prevents cleaning medium residue from remaining on the first surface to be cleaned, thereby improving cleaning quality. At the same time, in the first cleaning mode, the cleaning components can output a first rotation speed to match the first surface to be cleaned, which can better meet the cleaning needs of the first surface to be cleaned and more accurately control the cleaning action and pressure, thereby improving cleaning quality, reducing residue, and protecting the integrity of the first surface to be cleaned. Therefore, it can better adapt to the cleaning tasks and application scenarios of the first surface to be cleaned, enabling the cleaning equipment to provide a more comfortable and convenient cleaning experience. It has both wet and dry cleaning functions, is suitable for a wide range of scenarios, and has a better user experience.

[0356] It should be noted that the control device for cleaning equipment provided in the above embodiments is only illustrated by the division of the above functional modules. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the control device for cleaning equipment can be divided into different functional modules to complete all or part of the functions described above. In addition, the control device for cleaning equipment provided in the above embodiments and the control method embodiment for cleaning equipment belong to the same concept, and the specific implementation process is detailed in the foregoing method embodiment, which will not be repeated here.

[0357] Please refer to Figure 8, which is a schematic diagram of the structure of a control device for another cleaning device provided in an embodiment of this application. This application embodiment uses the control device in the processor of the cleaning device in this application embodiment as an example for illustrative explanation. The device includes at least a third control module 801.

[0358] The third control module 801 is used to respond to the switching trigger command of the first cleaning mode, control the liquid dispensing component to stop outputting cleaning medium to the cleaning component, and then control the cleaning equipment to perform dry cleaning on the first surface to be cleaned; wherein, in the first cleaning mode, the cleaning component outputs a first rotation speed.

[0359] By adopting the above technical solution, the control device of the cleaning equipment can switch between two cleaning modes. In the first cleaning mode, the cleaning equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the cleaning mode can be flexibly adjusted according to needs to adapt to the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The third control module 801 can respond to the switching trigger command of the first cleaning mode, controlling the dispensing component to stop outputting cleaning medium to the cleaning components, thereby controlling the cleaning equipment to achieve wet cleaning of the first surface to be cleaned. The dry cleaning method not only saves on cleaning media but also avoids the problem of the first surface to be cleaned being damp and difficult to dry, thus affecting the user experience. It also prevents cleaning media residue from remaining on the first surface, improving cleaning quality. Furthermore, in the first cleaning mode, the cleaning unit can output a specific rotation speed to match the first surface to be cleaned, better meeting its cleaning needs and allowing for more precise control of cleaning actions and pressure. This improves cleaning quality, reduces residue, and protects the integrity of the first surface. Therefore, it is better suited for cleaning tasks and application scenarios, providing a more comfortable and convenient cleaning experience. Combining wet and dry cleaning functions, it is suitable for a wide range of scenarios and offers a better user experience.

[0360] It should be noted that the control device for another cleaning device provided in the above embodiments is only illustrated by the division of the above functional modules. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the control device for the cleaning device can be divided into different functional modules to complete all or part of the functions described above. In addition, the control device for another cleaning device provided in the above embodiments and the control method embodiment for another cleaning device belong to the same concept, and the specific implementation process is detailed in the foregoing method embodiment, which will not be repeated here.

[0361] Please refer to Figure 9, which is a schematic diagram of the structure of a control device for a cleaning device provided in an embodiment of this application. This embodiment uses the control device in the processor of the cleaning device in this application as an example for illustrative purposes. The device includes at least a second scraper drive module 901 and a second control module 902.

[0362] The second scraper drive module 901 is used to control the first scraper to move in the first direction in response to the switching trigger command of the first cleaning mode, so that the first scraper and the cleaning component are spaced apart from each other.

[0363] The second control module 902 is used to control the liquid distribution component to stop outputting cleaning medium to the cleaning component and to control the liquid distribution component to provide cleaning medium to the suction pipe, thereby controlling the cleaning equipment to perform dry cleaning on the first surface to be cleaned; wherein, in the first cleaning mode, the cleaning component outputs a first rotation speed.

[0364] By adopting the above technical solution, the cleaning equipment is configured to switch between two cleaning modes. In the first cleaning mode, the equipment can perform dry cleaning on at least the first surface to be cleaned; in the second cleaning mode, it can perform wet cleaning on at least the second surface to be cleaned. Therefore, the two integrated cleaning modes can flexibly change according to needs to adapt to the surface to be cleaned. This allows for flexible selection of the most suitable cleaning method when dealing with different types of stains or surfaces with different characteristics, achieving efficient and high-quality cleaning results. Simultaneously, mode switching is convenient, reliable, and quick. The cleaning device includes a cleaning component, a dispensing assembly, a first scraper, and a suction pipe. In response to a switching trigger command for a first cleaning mode, the second scraper drive module 901 controls the spacing between the first scraper and the cleaning component. This prevents the first scraper from interfering with the movement path of the cleaning component during cleaning, avoiding additional friction on the cleaning component and thus preventing increased load on the drive component, which could affect its lifespan. It also prevents the cleaning component from affecting the cleaning effect on the first surface to be cleaned, allowing for more effective cleaning and improved cleaning efficiency. The second control module 902 controls the dispensing assembly to stop supplying liquid to the cleaning component. By dispensing cleaning media and controlling the cleaning equipment, a dry cleaning effect can be achieved on the first surface to be cleaned. This not only saves on the amount of cleaning media used but also avoids the situation where the first surface to be cleaned is damp and difficult to dry, thus preventing bacterial growth and affecting the user experience. It also prevents cleaning media residue from remaining on the first surface, thereby improving cleaning quality. Furthermore, in the first cleaning mode, the cleaning device controls the cleaning components to output a first rotational speed adapted to the first surface to be cleaned, better meeting the cleaning needs of the first surface and allowing for more precise control of cleaning actions and pressure, thereby improving cleaning quality, reducing residue, and... The first surface to be cleaned is protected for its integrity. The second control module 902, while controlling the dispensing component to stop outputting cleaning medium, also supplies cleaning medium to the suction pipe. This not only enables the cleaning equipment to perform dry cleaning of the first surface but also humidifies the cleaning debris sucked into the suction pipe. This effectively prevents dry cleaning debris from being directly sucked into the drive components connected to the suction pipe, thus avoiding increased wear and tear on the drive components and affecting their lifespan. It also prevents residual cleaning debris from floating in the suction pipe, which can cause difficulties in cleaning, increased maintenance, air quality issues, and reduced suction efficiency. Therefore, the cleaning equipment is better suited to the cleaning tasks and application scenarios of the first surface to be cleaned. This cleaning equipment provides a more comfortable and convenient cleaning experience, combining floor washing and dry vacuuming functions, making it suitable for a wide range of scenarios and offering a better user experience.

[0365] It should be noted that the control device for another type of cleaning equipment provided in the above embodiments is only illustrated by the division of the above functional modules. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the control device for the cleaning equipment can be divided into different functional modules to complete all or part of the functions described above. In addition, the control device for another type of cleaning equipment provided in the above embodiments and the control method embodiment for another type of cleaning equipment belong to the same concept, and the specific implementation process is detailed in the aforementioned method embodiment, which will not be repeated here.

[0366] Based on the above embodiments, the roller brush cleaning method provided in this application can be applied to the cleaning system 100a shown in FIG10.

[0367] The aforementioned cleaning system 100a includes a base station 112a, a device body 111a, and a control terminal 120a. The control terminal 120a is communicatively connected to a controller mounted on the base station 112a and a controller mounted on the device body 111a. When not performing ground cleaning work, the device body 111a can be placed in the base station 112a for charging.

[0368] Specifically, the device body 111a can be, but is not limited to, a sweeper, a mop, etc.

[0369] As shown in Figure 11, the base station 112a is provided with a receiving space 1121a and multiple liquid supply pipelines, and the receiving space 1121a can be provided with multiple liquid outlets, which are randomly distributed in the receiving space 1121a. When the device body 111a is placed on the base station 112a, the liquid supply pipeline of the base station 112a can be connected to the liquid storage space on the device body 111a, and the clean liquid stored in the liquid storage space can be input into the receiving space 1121a through the liquid outlets.

[0370] In one embodiment, the base station 112a may be provided with an additional liquid storage space. When the device body 111a is placed on the base station 112a, the liquid supply pipeline of the base station 112a can input the cleaning liquid stored in the liquid storage space on the base station 112a into the receiving space 1121a.

[0371] The control device 111a inputs cleaning liquid into the receiving space 1121a. The source of the cleaning liquid can be determined based on user input, pre-programmed settings, or actual conditions, and is not limited here. For example, if the base station 112a does not have a separate liquid storage space, the cleaning liquid will all come from the liquid storage space on the device 111a. Alternatively, if the base station 112a has a separate liquid storage space and the remaining liquid level meets the self-cleaning requirements, the cleaning liquid can be supplied from the separate liquid storage space on the base station 112a to execute the self-cleaning mode of the device 111a. If both the device 111a and the base station 112a have liquid storage spaces, the control device 111a and the base station 112a can also simultaneously input cleaning liquid into the receiving space 1121a.

[0372] In addition, a water-absorbing structure can be provided on the base station 112a, which is used to absorb water from the containing space 1121a.

[0373] The device body 111a has an installation cavity and a roller brush installed in the installation cavity for cleaning the floor. Additionally, the installation cavity of the device body 111a may also have liquid outlets. The liquid storage space on the device body 111a is used to spray stored cleaning liquid onto the roller brush through the liquid outlets in the installation cavity. The liquid outlets in the installation cavity may be randomly distributed on the surface of the installation cavity. Furthermore, the installation cavity of the device body 111a may also have a water-absorbing structure for absorbing water from the receiving space 1121a.

[0374] When the device body 111a is placed on the base station 112a, the roller brush on the device body 111a is placed in the accommodating space 1121a of the base station 112a.

[0375] After completing the ground cleaning task, the device body 111a returns to the base station 112a. At this time, the roller brush on the device body 111a is placed in the receiving space 1121a of the base station 112a. The liquid supply line of the base station 112a is connected to the liquid storage space on the device body 111a. If both the device body 111a and the base station 112a receive the cleaning command issued by the controller 130a, the base station 112a can input the cleaning liquid stored in the liquid storage space on the device body 111a into the receiving space 1121a through the liquid supply line and the liquid outlet in the receiving space 1121a. At the same time, the device body 111a can spray the cleaning liquid stored in the liquid storage space onto the surface of the roller brush through the liquid outlet in the mounting cavity to clean the roller brush.

[0376] Furthermore, after the roller brush cleaning is completed, the base station 112a can use the water absorption structure to suck the cleaning liquid in the containing space 1121a into the wastewater tank set on the base station 112a. Alternatively, the equipment body 111a can use the water absorption structure in the installation cavity to suck the cleaning liquid in the containing space 1121a into the wastewater tank set on the equipment body 111a.

[0377] Specifically, the water outlet of each liquid outlet in base station 112a is tilted downward and tangent to the outer circumference of the roller brush. In this way, the wastewater generated after the cleaning liquid cleans the roller brush can flow directly into the receiving space 1121a and then be pumped away by the water absorption structure and discharged, without re-contaminating the area on the roller brush that has already been cleaned.

[0378] In this embodiment, the roller brush does not require manual cleaning, reducing the difficulty of manual cleaning. Furthermore, during roller brush cleaning, the device body 111a can improve the cleaning effect by controlling the roller brush to rotate alternately in both directions.

[0379] In one possible implementation, the base station 112a is also provided with at least one heating element for generating heat toward the receiving space 1121a. As an example, the heating element may surround a surface disposed in the receiving space 1121a.

[0380] In one possible implementation, the heating element may be, for example, an infrared heater, and at least a portion of the surface of the receiving space 1121a is a transmissive plate. The infrared heater disposed in the receiving space 1121a is used to emit infrared rays, and at least a portion of the infrared rays are radiated into the receiving space 1121a through the transmissive plate. As an example, the infrared heater may be disposed at the bottom of the receiving space 1121a.

[0381] In one possible implementation, Hall effect sensors can be installed on both sides of the corresponding roller brush in the receiving space 1121a of base station 112a to detect magnetic fields. Correspondingly, magnets can be embedded on both sides of specific types of roller brushes, such as bristle brushes. When the roller brush on the device body 111a is placed in the receiving space 1121a of base station 112a, the Hall effect sensors can monitor the surrounding magnetic field in real time. When the Hall effect sensors detect a magnetic field, they can output a Hall voltage signal. Base station 112a can send this Hall voltage signal to control terminal 120a. Based on the Hall voltage signal, control terminal 120a determines that the roller brush placed in receiving space 1121a is a bristle brush. When the Hall effect sensors do not detect a magnetic field, they do not output a Hall voltage signal. At this time, control terminal 120a can determine that the roller brush placed in receiving space 1121a is of a type other than a bristle brush, such as a velvet brush.

[0382] As shown in Figure 12, in one possible implementation, the roller brush mounted on the device body 111a can include at least two types: a first roller brush and a second roller brush. The first roller brush includes a bristle brush, and the second roller brush includes a bristle-embedded brush. The bristle-embedded brush includes a main body, multiple first brush strips 302a, and multiple second brush strips 304a. The first brush strips 302a and the second brush strips 304a are respectively arranged circumferentially on the outer surface of the main body. The first brush strips 302a and the second brush strips 304a are made of different materials.

[0383] In one embodiment, the diameter of the bristle brush is smaller than that of the down brush.

[0384] As shown in Figure 13, compared to a fluff brush, the bristle brush has no fluff covering its surface. In order to avoid the toothed hanging strip 402a that is commonly used for fluff brushes in the installation cavity of cleaning equipment, the diameter of the bristle brush is generally set to be smaller than that of the fluff brush (the black circle is the outer diameter of the fluff brush, and the red circle is the outer diameter of the bristle brush).

[0385] Furthermore, the smaller bristle brushes generate stronger shearing force when rotating, which is used to clean stains and fibers adhering to the surface to be cleaned, thus improving the cleaning efficiency of carpets.

[0386] In one embodiment, the second brush strip 304a is made of the same material as the bristle brush.

[0387] The first brush bar 302a can be a stiff bristle brush bar, and the second brush bar 304a can be a soft bristle brush bar.

[0388] Compared to stiff bristle brush strips, fluffy brush strips have a larger brush area and a finer bristle structure, resulting in better water absorption. This allows the flocked brush with fluffy brush strips to absorb liquid stains more quickly. When the surface to be cleaned is a carpet, the fluffy brush strips on the flocked brush can quickly absorb liquid stains on the carpet, thereby improving the cleaning effect of the carpet.

[0389] Furthermore, the soft bristles of the fluffy brush strip can better agitate and disperse the cleaning liquid. As a result, when the device body 111a is placed on the base station 112a, the cleaning liquid in the containing space 1121a can more evenly clean the hard bristle brush strip and fluffy brush strip on the surface of the bristle brush, thereby improving the cleaning effect of the roller brush.

[0390] In one embodiment, the coverage area of ​​the second brush strip 304a on the outer surface of the body does not exceed the coverage area of ​​the first brush strip 302a on the outer surface of the body.

[0391] If the bristle strips are designed to be too dense, it may increase the friction of the roller brush, affecting its rotation efficiency and potentially damaging the carpet. In addition, overly dense bristles may cause the brushes to tangle, affecting cleaning effectiveness and lifespan. On the other hand, stiff bristle strips are better at removing harder dust and impurities, and their large coverage area contributes to the overall cleaning effect. To balance cleaning effectiveness and efficiency, limiting the coverage area of ​​the bristle strips ensures that the bristle brush can reduce damage to the carpet while maintaining cleaning efficiency.

[0392] In this embodiment, the bristle brush adds a fluffy brush strip to the traditional bristle brush that only has stiff bristle strips. The fluffy brush strip can quickly absorb liquid stains on the carpet, thereby improving the cleaning effect of the bristle brush on the carpet; and the fluffy brush strip enhances the agitation effect on the cleaning liquid, thereby improving the self-cleaning effect of the bristle brush.

[0393] In one embodiment, a roller brush cleaning method is provided. This embodiment illustrates the application of this roller brush cleaning method to a control terminal in any of the above embodiments. As shown in Figure 14, the roller brush cleaning method includes:

[0394] Step 1402: In response to a cleaning instruction, when the roller brush mounted on the cleaning device is placed in the receiving space, the target type of the roller brush is determined; wherein the target type includes at least a first roller brush and a second roller brush; the first roller brush includes a bristle brush and the second roller brush includes a bristle brush, the bristle brush and the bristle brush have different surface structures and are used to clean different surfaces or areas to be cleaned.

[0395] A cleaning instruction refers to an instruction to self-clean the roller brush mounted on the cleaning equipment.

[0396] The cleaning instructions can be issued by staff through the human-machine interface of the control terminal. Specifically, the control terminal's human-machine interface can display a platform interface pre-designated by the cleaning system service provider for controlling the cleaning system. Users can issue cleaning instructions by clicking on a pre-integrated virtual component on the designated platform interface to instruct the roller brush to self-clean. Alternatively, the cleaning instructions can be automatically generated by the control terminal when it detects that the cleaning equipment has been placed on the base station for a preset period of time.

[0397] The first and second roller brushes indicate two different types of roller brushes. As an example, cleaning equipment can be equipped with different types of roller brushes, such as common floor brushes (i.e., plush brushes) or carpet brushes (i.e., flocked brushes). The main difference between stiff-bristled flocked brushes and ordinary plush brushes lies in their structure and cleaning function. Flocked brushes typically have stiffer and shorter bristles, and are usually made of harder materials such as nylon to enhance the cleaning effect on carpet fibers. They are suitable for short-pile carpets, rugs, and other similar materials. Ordinary plush brushes, on the other hand, are suitable for hard surfaces such as tile, wood flooring, and marble, and their bristles are usually softer and longer. Furthermore, to avoid the wringing strip used for floor brushes, the outer diameter of the bristle brush body is usually smaller than that of the floor brush. Compared to the distance between the floor brush and the bottom of the receiving space, the distance between the bristle brush and the bottom of the receiving space is greater. Moreover, the bristle brush cannot thoroughly clean the receiving space through its bristles during rotation. Therefore, during the self-cleaning stage of the roller brush, the stains attached to the surface of the bristle brush will gradually accumulate at the edge of the receiving space due to the surge caused by the rotation of the roller brush, resulting in stain residue in the receiving space after cleaning, thus reducing the self-cleaning effect.

[0398] In this embodiment, the target type refers, for example, to a stiff-bristled brush. Magnets can be pre-installed on both sides of the brush. When the roller brush on the cleaning device is placed in the base station's receiving space, a Hall plate in the receiving space can monitor the surrounding magnetic field in real time. When the Hall plate detects a magnetic field, it outputs a Hall voltage signal. The base station can send this Hall voltage signal to the control terminal. Based on this Hall voltage signal, the control terminal determines that the roller brush placed in the receiving space is a stiff-bristled brush. When the Hall plate does not detect a magnetic field, it does not output a Hall voltage signal, and the control terminal can determine that the brush placed in the receiving space is not a stiff-bristled brush. It should be noted that by changing the type of roller brush equipped with magnets, different types of roller brushes can be identified, further enabling differentiated self-cleaning treatment for different types of roller brushes.

[0399] Step 1404a: When the target type indicates that the roller brush is a bristle brush, control the base station to execute the first self-cleaning mode.

[0400] Step 1404b: When the target type indicates that the roller brush is a bristle brush, control the base station to execute the second self-cleaning mode.

[0401] Specifically, the base station is controlled to execute the first self-cleaning mode, including:

[0402] Control the cleaning equipment to input the first volume of cleaning liquid into the receiving space, and control the cleaning equipment to perform the cleaning action;

[0403] The cleaning device is controlled to input a second volume of cleaning liquid into the receiving space, and the cleaning device is controlled to perform cleaning actions. The process of controlling the cleaning device to input a second volume of cleaning liquid into the receiving space and controlling the cleaning device to perform cleaning actions is repeated until the first self-cleaning mode is completed.

[0404] Control the base station to execute the second self-cleaning mode, including:

[0405] Control the cleaning equipment to input a third volume of cleaning liquid into the receiving space, and control the cleaning equipment to perform cleaning actions;

[0406] The cleaning equipment is controlled to input a fourth volume of cleaning liquid into the receiving space, and the cleaning equipment is controlled to perform a cleaning action. The process of controlling the cleaning equipment to input a fourth volume of cleaning liquid into the receiving space and controlling the cleaning equipment to perform a cleaning action is repeated until the second self-cleaning mode is completed; the third volume of water is less than the first volume of water, and the fourth volume of water is less than the third volume of water.

[0407] Specifically, in this embodiment, when the control terminal determines that the roller brush placed in the receiving space is a bristle brush, it can generate a first water discharge command and send it to the base station. This controls the base station to input a first amount of cleaning liquid into the receiving space within a first preset time period to clean the roller brush. The primary function of the first amount of cleaning liquid is to wet the surface of the bristle brush, softening and loosening the dust, dirt, and oil adhering to the bristles, making them easier to remove. Subsequently, the control terminal can generate a second water discharge command and send it to the base station. This controls the base station to input a second amount of cleaning liquid into the receiving space within a second preset time period to repeatedly clean the roller brush until the first self-cleaning mode is completed.

[0408] In this embodiment, the control terminal can also generate a third water discharge command and send it to the base station when it determines that the roller brush placed in the receiving space is a bristle brush. This controls the base station to input a third volume of cleaning liquid into the receiving space within a third preset time period to clean the roller brush. The first volume of cleaning liquid mainly serves to wet the surface of the bristle brush, softening and loosening the dust, dirt, and oil stains attached to the bristles, making them easier to remove. Subsequently, the control terminal can generate a fourth water discharge command and send it to the base station. This controls the base station to input a fourth volume of cleaning liquid into the receiving space within a fourth preset time period to repeatedly clean the roller brush until the execution of the first self-cleaning mode is completed.

[0409] It should be noted that the flow rate of the cleaning liquid input into the base station's space per unit time can be kept constant. By controlling the input duration of the cleaning liquid, dynamic regulation of the water volume can be achieved. As an example, the second preset duration can be less than or equal to the first duration, thereby controlling the second water volume to be less than or equal to the first water volume; the third preset duration can be less than the first duration, thereby controlling the third water volume to be less than the first water volume; and the fourth preset duration can be less than the third duration, thereby controlling the fourth water volume to be less than the third water volume.

[0410] For the bristle brush, after the first volume of cleaning liquid is used for cleaning, there may be residual cleaning liquid in the container space and on the bristle brush. If the second volume of water is greater than the first volume, the liquid level in the container space may be too high. When the liquid level in the container space reaches the failure level shown in Figure 15, if the cleaning equipment rotates the bristle brush at this time, the surge caused by the rotation of the bristle brush may wash the dirt into the cleaning dead corner area 602 in the container space, thereby affecting the self-cleaning efficiency of the cleaning system. At this time, the control terminal can generate a second water discharge command and send it to the base station to control the base station to input a second volume of cleaning liquid into the container space. At this time, the second volume of water is less than the first volume of water to improve the cleaning effect of the bristle brush.

[0411] Alternatively, since the bristles of the soft brush are relatively soft and long, the brush has a good water absorption rate. The first volume of cleaning liquid that the base station initially inputs into the containment space can be considered to be completely absorbed by the brush. In other words, it can be understood that there is no residue of the cleaning liquid that the base station initially inputs into the containment space. At this time, the control terminal can generate a second water release command and send it to the base station to control the base station to input a second volume of cleaning liquid into the containment space. At this time, the second volume of water is equal to the first volume of water.

[0412] This can be understood as follows: when the cleaning system is self-cleaning the bristle brush, the cleaning liquid introduced into the containment space in the second and subsequent cycles can always be kept at the same initial volume to achieve thorough cleaning of the bristle brush.

[0413] Compared to fluffy brushes, bristle brushes are smaller and have poorer water absorption. They are less likely to sink to the bottom of the receiving space. If the initial volume of cleaning liquid used to clean the bristle brush is greater than or equal to the initial volume used to clean the fluffy brush, the rotation of the bristle brush will inevitably cause waves in the cleaning liquid within the receiving space. This will wash away dirt into the cleaning dead zones 602 within the receiving space. Therefore, it is necessary to reduce the initial volume of cleaning liquid used to clean the bristle brush. Furthermore, considering that some cleaning liquid residue may remain in the receiving space and on the bristle brush after the third volume of cleaning liquid, the cleaning effect can be improved by further reducing the volume of cleaning liquid input to the receiving space to a fourth volume when repeatedly cleaning the bristle brush.

[0414] The cleaning actions described above may include, for example, slow and fast rotation of the roller brush, wherein slow rotation is used to evenly wet the roller brush to clean the surface of the roller brush with cleaning liquid, and fast rotation is used to quickly spin-dry the roller brush.

[0415] It should be noted that after the cleaning equipment completes the cleaning action, the control terminal can also generate a water discharge command and send it to the base station, thereby controlling the water suction structure in the base station to pump away the wastewater generated after the cleaning liquid cleans the roller brush.

[0416] In one possible implementation, the control terminal can generate a first, second, third, or fourth water discharge command and send it to at least one of the base station and the cleaning equipment, thereby controlling the base station and / or the cleaning equipment to input cleaning liquid into the containment space until the total amount of cleaning liquid input into the containment space reaches the first, second, third, or fourth water volume. Furthermore, after the cleaning equipment completes the cleaning action, the control terminal can also generate a water discharge command and send it to at least one of the base station and the cleaning equipment, thereby controlling the water suction structure in the base station and / or the water suction structure in the cleaning equipment to remove the wastewater generated after the cleaning liquid cleans the roller brush.

[0417] Furthermore, there are multiple methods to determine whether the first self-cleaning mode or the second self-cleaning mode has ended. For example, before issuing a cleaning command by clicking the virtual component used to instruct the roller brush to self-clean on the human-interaction interface of the control terminal, the user can also click the conditional virtual component used to instruct the self-cleaning duration or the conditional virtual component used to instruct the number of times the roller brush is cleaned repeatedly, so as to clarify the conditions for the first self-cleaning mode to end or the second self-cleaning mode to end.

[0418] As an example, the control terminal can also start timing when the first water discharge command or the third water discharge command is generated, and determine the end of the first self-cleaning mode or the second self-cleaning mode when the timing reaches the self-cleaning time corresponding to the condition virtual component. Alternatively, the control terminal can count the number of times the cleaning device performs cleaning actions, and determine the completion of the roller brush cleaning task when the number of times reaches the water discharge number corresponding to the condition virtual component.

[0419] Alternatively, sensors can be installed in the base station, and the control terminal can determine whether the roller brush is clean based on the data collected by the sensors, and determine that the cleaning task of the roller brush is completed when it is determined that the roller brush is clean.

[0420] The aforementioned roller brush cleaning method can achieve automatic identification of roller brush type with minimal modifications to the base station and the roller brush, thereby reducing manual operation and improving the efficiency and automation of the cleaning system. Secondly, it can adaptively adjust the roller brush cleaning process according to the type of roller brush: after confirming that it is a bristle brush, a larger amount of cleaning liquid is used for deep cleaning in the first step, which helps to remove stubborn dirt and residue; and in the second and subsequent repeated cleaning, the amount of water is reduced to avoid stains being washed into the cleaning dead areas in the containment space, thereby ensuring the self-cleaning efficiency of the cleaning system. With minimal modification costs, existing base stations can be made compatible with self-cleaning of bristle brushes, improving the versatility of base stations.

[0421] In some optional embodiments, the cleaning equipment is also equipped with a wastewater tank;

[0422] Before step 1404, the following are also included:

[0423] The cleaning equipment is controlled to rotate the roller brush along a first direction at a first rotation speed to leave the objects adhering to the roller brush in the receiving space, and the cleaning equipment is controlled to suck the objects in the receiving space into the sewage tank.

[0424] The first direction can be, for example, clockwise, and the first rotation speed can be understood as a low rotation speed. At the first rotation speed, the roller brush will generate a small centripetal force to prevent excessive centripetal force from throwing the dirt adhering to the roller brush to places that the water flow cannot cover.

[0425] In this embodiment, before the cleaning liquid is introduced, the control terminal can generate a low-speed rotation command and send it to the cleaning equipment to control the cleaning equipment to rotate the roller brush at a low speed, thereby removing larger objects, i.e., stains, adhering to the roller brush into the receiving space. Furthermore, the control terminal can generate a water discharge command and send it to the base station, thereby controlling the water suction structure in the base station to suck the stains in the receiving space into the wastewater tank.

[0426] The above-described roller brush cleaning method involves rotating the roller brush at low speed before using cleaning liquid to preferentially remove larger objects, such as dry or semi-solid dirt, from the bristles using centrifugal force, preventing these stains from sticking together when exposed to water. By removing larger dirt, and then dissolving the remaining stains with cleaning liquid, the wastewater generated during subsequent cleaning can be more easily absorbed, preventing the dissolution of larger stains into high-concentration sludge that can clog cleaning equipment or base stations. This reduces the amount of cleaning liquid used and simultaneously improves cleaning efficiency, achieving a more thorough and efficient cleaning effect.

[0427] In some optional embodiments, the cleaning equipment is also equipped with a wastewater tank;

[0428] Controlling cleaning equipment to perform cleaning actions includes:

[0429] Control the cleaning equipment to rotate the roller brush along the second direction and at the second rotation speed so as to clean the roller brush with cleaning liquid;

[0430] The cleaning equipment is controlled to rotate the roller brush along the first direction at a third rotation speed to dry the roller brush, while simultaneously controlling the cleaning equipment to suck the cleaning liquid in the containment space into the sewage tank; the third rotation speed is greater than the second rotation speed.

[0431] The second and third speeds are both greater than the first speed.

[0432] The second direction can be, for example, counterclockwise. Typically, the bristles of most roller brushes are arranged at an angle. When the roller brush rotates counterclockwise, the bristles will naturally spread out, thereby increasing the contact area with the cleaning liquid and improving the efficiency of dissolving and removing dirt.

[0433] In this embodiment, after the control terminal controls the base station to input cleaning liquid into the accommodating space, it can further control the cleaning device to rotate the roller brush along the second direction at the second rotation speed, so that the cleaning liquid can wet the roller brush and dissolve the dirt adhering to the roller brush. Subsequently, the control terminal can control the cleaning device to rotate the roller brush along the first direction at the third rotation speed, so that the high-speed rotation of the roller brush generates a strong centripetal force, thereby throwing out the deep dirt (such as oil stains and sticky particles) from the brush bristles.

[0434] The above-mentioned roller brush cleaning method involves first rotating at a low speed to allow the cleaning liquid to evenly soak and cover the bristles of the roller brush, ensuring that the entire surface of the roller brush is fully wetted, which helps to soften dirt and improve the cleaning effect; then rotating at a high speed can quickly shake off excess water, allowing the roller brush to generate strong centripetal force through high-speed rotation, thereby shaking out deep dirt from the bristles, thus improving cleaning efficiency and ensuring cleaning effect.

[0435] In some optional embodiments, the base station is also provided with at least one heating element for generating heat toward the accommodating space;

[0436] Following step 1406, the following also includes:

[0437] The base station is controlled to activate the heating element to perform the drying task on the roller brush.

[0438] After the control terminal determines that the cleaning task of the roller brush is completed, it can generate a heating command and send it to the base station to control the base station to turn on the heating element. The heating element generates heat towards the receiving space to gradually increase the temperature in the receiving space, thereby accelerating the evaporation of residual moisture on the roller brush and completely removing the residual moisture from the roller brush.

[0439] The above-mentioned roller brush cleaning method can quickly evaporate the residual moisture on the roller brush by turning on the heating element, thereby shortening the drying time of the roller brush and improving the overall working efficiency of the cleaning equipment; thorough drying avoids a humid environment, which can effectively inhibit the growth of bacteria, mold and odors on the roller brush and extend the service life of the roller brush.

[0440] In some optional embodiments, the base station is also provided with at least one fan and a corresponding air duct for the fan, and the heating element is disposed in the air duct. The air blown out by the fan passes through the corresponding air duct and delivers the heat generated by the heating element to the accommodating space.

[0441] Following step 1406, the following also includes:

[0442] The control base station turns on the fan and heating element to perform the drying task of the roller brush.

[0443] After the control terminal determines that the cleaning task of the roller brush is completed, it can generate a heating command and send it to the base station to control the base station to turn on the heating element. At the same time, it can generate a blowing command and send it to the base station to control the base station to turn on the fan. At this time, the fan can transfer the heat generated by the heating element to the roller brush, which can effectively increase the heat transferred to the roller brush, reduce heat loss, and the hot air continues to flow, quickly removing the moisture and humidity on the roller brush, accelerating the drying process, thereby effectively improving the drying effect of the heating element on the roller brush.

[0444] The above-mentioned roller brush cleaning method allows hot air to quickly evaporate residual moisture on the roller brush, shortening the drying time. By evenly delivering hot air to all parts of the roller brush through the air duct, the problem of localized dampness or uneven drying can be avoided, ensuring that the roller brush is dry overall. This prevents bacterial growth and odor formation, and extends the service life of the roller brush.

[0445] In some optional embodiments, after controlling the base station to turn on the fan and heating element to perform the drying task of the roller brush, the method further includes:

[0446] The control base station shuts down the heating element, allowing the fan to deliver the air it blows through the corresponding air duct to the containment space to cool the roller brush.

[0447] After the roller brush has finished drying, the control terminal generates a stop heating command and sends it to the base station. This command shuts down the heating element to stop heat generation and prevent overheating, which could damage the equipment and roller brush in the storage space. Meanwhile, the fan in the base station continues to operate, delivering cool air through ducts to the storage space containing the roller brush. This cool air flow gradually removes residual heat from the roller brush surface, helping it cool down to a safe temperature. This ensures the roller brush is thoroughly dried without deforming or having its lifespan shortened due to overheating.

[0448] In this embodiment, the cooling process can be performed only after the drying of the bristle brush. The reason is as follows: With common bristle brushes, the heat generated by the heating element is mainly concentrated on the surface layer of the bristle fibers because the surface is covered with bristles. Furthermore, due to the fluffy texture and large gaps in the bristles, heat can dissipate quickly through natural convection and radiation. Therefore, bristle brushes do not require additional heat dissipation after drying. However, the bristle-covered area on a bristle brush is smaller, and the heat generated by the heating element during drying tends to accumulate near the motor shaft, causing the localized temperature of the roller brush to become excessively high. Without additional heat dissipation, this will lead to material aging of the roller brush or an increased load on the motor of the cleaning equipment. Therefore, in this embodiment, a fan is used to cool the roller brush.

[0449] The above-mentioned roller brush cleaning method can cool down the roller brush after drying, thereby avoiding deformation, cracking or other thermal damage caused by high temperature, thus extending the roller brush's lifespan. By cooling down the roller brush in time, safety hazards caused by excessive roller brush temperature can be avoided, ensuring user safety.

[0450] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0451] Based on the same inventive concept, this application also provides a roller brush cleaning device for implementing the roller brush cleaning method described above. The solution provided by this roller brush cleaning device is similar to the solution described in the roller brush cleaning method above. Therefore, the specific limitations in one or more device embodiments provided below can be found in the limitations of the roller brush cleaning method described above, and will not be repeated here.

[0452] In one embodiment, as shown in FIG16, a roller brush cleaning device 1600 is provided. The roller brush cleaning device 1600 is applied to the control terminal 120a in the cleaning system 100a. The cleaning system 100a also includes a base station 112a and a device body 111a connected to the control terminal 120a. The base station 112a is provided with a receiving space for accommodating the roller brush mounted on the cleaning device.

[0482] The specific implementation process of processor 1701 can be found in the above method embodiments, and its implementation principle and technical effect are similar. It will not be repeated here.

[0489] With the widespread use of flooring products such as carpets in homes, household cleaning needs are no longer limited to traditional floor cleaning. Different cleaning methods are required for different surface materials, and the roller brush, a core component of cleaning equipment, also needs to be adapted to different materials.

[0490] Currently, most floor scrubbers are only used for wet cleaning of floors. For carpet cleaning, the floor scrubber is usually replaced with a vacuum cleaner to clean the carpet directly. When cleaning the floor, the floor scrubber is switched back. This back-and-forth switching of different cleaning equipment not only requires users to purchase two different cleaning devices, increasing their equipment investment, but also makes daily cleaning work more troublesome.

[0491] In view of this, and in conjunction with Figures 18 to 26, embodiments of this application provide a multi-stage roller brush drive device, which aims to overcome at least one of the above-mentioned technical problems.

[0492] Referring to Figures 18 to 21, a multi-stage roller brush drive device 1b includes a base frame 10b, a transmission mechanism 11b, and a drive component 12b.

[0493] It is understandable that, in order to adapt to the roller brush structure and reduce space occupation, the multi-stage roller brush drive device 1b in this application embodiment is arranged inside the roller brush along the axial direction of the roller brush, that is, after the roller brush is installed, the entire roller brush is sleeved on the outside of the multi-stage roller brush drive device 1b.

[0494] The drive member 12b and the transmission mechanism 11b are mounted on the base frame 10b along the axial direction of the roller brush. The transmission mechanism 11b has a power input end, a first output shaft 110b and a second output shaft 111b. The first output shaft 110b and the second output shaft 111b are coaxially arranged and are respectively connected to the power input end. The drive end 120b of the drive member 12b is connected to the power input end.

[0495] Specifically, referring to Figures 20 and 21, the base frame 10b adopts a split structure, including a main body 100b with an opening at one end and a cover 101b covering the opening. To facilitate quick installation, the transmission mechanism 11b and the drive component 12b can be fixed to the cover 101b first, and then the whole assembly is placed on the main body 100b.

[0496] Referring to Figures 20 and 21, a through hole 1100b is provided through the first output shaft 110b along its own axial direction, and the first output shaft 110b has a first end 1101b away from the power input end in its own axial direction. A second output shaft 111b partially passes through the through hole 1100b and is coaxially arranged with the first output shaft 110b, and the second output shaft 111b has a second end 1110b away from the power input end in its own axial direction, and the second end 1110b protrudes from the first end 1101b.

[0497] The first output shaft 110b is sleeved on the outside of the second output shaft 111b using a through hole 1100b structure to achieve coaxial arrangement of the first output shaft 110b and the second output shaft 111b. The second end 1110b protrudes from the first end 1101b to ensure that the first output shaft 110b and the second output shaft 111b have reserved space for connecting the corresponding roller brushes, thus avoiding mutual interference.

[0498] Corresponding to the first output shaft 110b and the second output shaft 111b in the embodiments of this application, for example, the embodiments of this application introduce a first roller brush 3b and a second roller brush 4b. The first roller brush 3b can be a soft brush or the like, mainly used to connect to the first output shaft 110b and for use during wet cleaning operations. The second roller brush 4b can be a hard-toothed brush or the like, mainly used to connect to the second output shaft 111b and for use in conjunction with vacuuming operations.

[0499] Specifically, when cleaning wooden floors or tile surfaces, the first roller brush 3b can be selected for wet cleaning to increase the contact area between the surface and the first roller brush 3b, thus improving the cleaning effect. When cleaning carpets or other surfaces, the second roller brush 4b can be selected for vacuuming, increasing the contact depth between the surface and the second roller brush 4b, thereby improving the vacuuming effect.

[0500] The drive component 12b can be a motor. Power is output through the drive component 12b so that the first output shaft 110b can drive the first roller brush 3b to output a first speed, and the second output shaft 111b can drive the second roller brush 4b to output a second speed. The first speed and the second speed are not equal. In this embodiment, the actual second speed is greater than the first speed.

[0501] In other embodiments, the transmission mechanism 11b may also be provided with more output shafts, and corresponding roller brushes may be provided to ensure that the roller brushes work at the corresponding working speed.

[0502] When using the multi-stage roller brush drive device 1b, select the appropriate first roller brush 3b or second roller brush 4b according to the material of the surface to be cleaned. If wet cleaning of the floor is required, select the first roller brush 3b. At this time, install the first roller brush 3b onto the first output shaft 110b. Input power to the power input end of the transmission mechanism 11b through the drive member 12b, and drive the first roller brush 3b to rotate at the first speed by the first output shaft 110b, so that the first roller brush 3b cleans the surface to be cleaned at the first speed.

[0503] Similarly, if vacuuming is required for carpet cleaning, the second roller brush 4b is selected and installed on the second output shaft 111b. Power is input to the power input end of the transmission mechanism 11b through the drive component 12b, and the second output shaft 111b drives the second roller brush 4b to rotate at the second speed, thereby cleaning the surface to be cleaned by the second roller brush 4b at the second speed.

[0504] It is understandable that in order to simultaneously perform wet cleaning and vacuuming operations, the multi-stage roller brush drive device 1b in this embodiment needs to be installed on a cleaning device capable of independently performing wet cleaning and vacuuming operations. For example, if the cleaning device is a floor scrubber, then during vacuuming operations, the cleaning device can stop spraying water towards the surface to be cleaned or the roller brush and only suck up the dust from the surface to be cleaned.

[0505] The power source of the same drive element 12b outputs different speeds via the transmission mechanism 11b to adapt to the working speed required by different surfaces to be cleaned, eliminating the need to change different cleaning equipment and improving the convenience of cleaning operations. In addition, the coaxial arrangement of the first output shaft 110b and the second output shaft 111b reduces the overall space occupied by the multi-stage roller brush drive device 1b compared to parallel arrangement, and reduces the impact on the appearance of the cleaning product.

[0506] Specifically, in some embodiments, the first rotational speed is V1, which satisfies: 480 rpm / min ≤ V1 ≤ 600 rpm / min.

[0507] Wherein, V1 can be any value from 480 rpm / min to 600 rpm / min; for example, it can be a range of any one or any two of the following: 480 rpm / min, 485 rpm / min, 490 rpm / min, 495 rpm / min, 500 rpm / min, 505 rpm / min, 510 rpm / min, 515 rpm / min, 520 rpm / min, 525 rpm / min, 530 rpm / min, 535 rpm / min, 540 rpm / min, 545 rpm / min, 550 rpm / min, 555 rpm / min, 560 rpm / min, 565 rpm / min, 570 rpm / min, 575 rpm / min, 580 rpm / min, 585 rpm / min, 590 rpm / min, 595 rpm / min, and 600 rpm / min.

[0508] In some embodiments, the second rotational speed is V2, which satisfies: 2300 rpm / min ≤ V2 ≤ 2600 rpm / min.

[0509] Where V2 can be any value from 2300 rpm / min to 2600 rpm / min; for example, it can be 2300 rpm / min, 2305 rpm / min, 2310 rpm / min, 2315 rpm / min, 2320 rpm / min, 2325 rpm / min, 2330 rpm / min, 2335 rpm / min, 2340 rpm / min, 2345 rpm / min, 2350 rpm / min, 2355 rpm / min, 2360 rpm / min, 2365rpm / min, 2370rpm / min, 2375rpm / min, 2380rpm / min, 2385rpm / min, 2390rpm / min, 2395rpm / min, 2400rpm / min, 240 5rpm / min, 2410rpm / min, 2415rpm / min, 2420rpm / min, 2425rpm / min, 2430rpm / min, 2435rpm / min, 2440rpm / min, 2445rp m / min, 2450rpm / min, 2455rpm / min, 2460rpm / min, 2465rpm / min, 2470rpm / min, 2475rpm / min, 2480rpm / min, 2485rpm / m in, 2490rpm / min, 2495rpm / min, 2500rpm / min, 2505rpm / min, 2510rpm / min, 2515rpm / min, 2520rpm / min, 2525rpm / min, A range of values ​​consisting of any one or any two of the following: 2530 rpm / min, 2535 rpm / min, 2540 rpm / min, 2545 rpm / min, 2550 rpm / min, 2555 rpm / min, 2560 rpm / min, 2565 rpm / min, 2570 rpm / min, 2575 rpm / min, 2580 rpm / min, 2585 rpm / min, 2590 rpm / min, 2595 rpm / min, and 2600 rpm / min.

[0510] Setting the first rotation speed between 480 rpm / min and 600 rpm / min is more suitable for wet cleaning of surfaces using cleaning equipment such as floor scrubbers. If the first rotation speed is too low, the wet cleaning effect will be poor, and the frequency of brushing the surface to be cleaned will be low per unit time. Since the first roller brush 3b needs to be wetted before brushing, if the first rotation speed is too high, the first roller brush 3b may splash water on the surface to be cleaned, resulting in residual water stains.

[0511] The second speed is set between 2300 rpm / min and 2600 rpm / min. The second speed is more suitable for vacuuming the surface to be cleaned when using cleaning equipment such as floor scrubbers. At this time, the surface to be cleaned can be a carpet. Using a higher speed can improve the cleaning effect on similar types of surfaces to be cleaned, such as carpets. The second roller brush 4b can quickly brush out the impurities mixed in the carpet and stir up the dust in the carpet, making it easier to pick up and collect dust and other impurities.

[0512] The following mainly describes how the transmission mechanism 11b used in the embodiments of this application outputs different speeds from the same driving element 12b:

[0513] In some embodiments, referring to Figures 20, 21, 24, and 25, the transmission mechanism 11b further includes a housing 114b, a first planetary gear set 112b, and a second planetary gear set 113b.

[0514] The housing 114b is housed within the base frame 10b. Specifically, the housing 114b can be fixed to the cover 101b. The housing 114b has a transmission cavity 1140b and an opening facing the main body 100b. The first output shaft 110b is rotatably connected to the housing 114b via a bearing 1142b. Parts of the first output shaft 110b and the second output shaft 111b both pass through the transmission cavity 1140b. An internal gear ring 1141b is provided on the inner wall of the transmission cavity 1140b surrounding the axis of the first output shaft 110b. The drive member 12b is mounted on the opening of the housing 114b via a fixing seat 121b and seals the opening. The drive end 120b of the drive member 12b extends into the transmission cavity 1140b. The first planetary gear set 112b and the second planetary gear set 113b are sequentially arranged in the transmission cavity 1140b along the axial direction of the first output shaft 110b, and the first planetary gear set 112b is located on the side of the second planetary gear set 113b facing the drive member 12b.

[0515] The first planetary gear 112b includes a first sun tooth 1120b, a plurality of first planetary teeth 1122b, and a first planetary carrier 1121b. The first sun tooth 1120b and the first planetary teeth 1122b are respectively located on the side of the first planetary carrier 1121b facing the drive member 12b.

[0516] The first sun tooth 1120b is connected to the drive end 120b, and the connection end of the first sun tooth 1120b and the drive end 120b constitutes the power input end. Multiple first planetary teeth 1122b are rotatably connected to the first planetary carrier 1121b, and the multiple first planetary teeth 1122b are circumferentially arranged around the rotation center of the first sun tooth 1120b. The multiple first planetary teeth 1122b respectively mesh with the first sun tooth 1120b and the internal gear ring 1141b.

[0517] The second planetary carrier 113b includes a second sun tooth 1130b, a plurality of second planetary teeth 1132b, and a second planetary carrier 1131b. The second sun tooth 1130b and the second planetary teeth 1132b are respectively located on the side of the second planetary carrier 1131b facing the first planetary carrier 1121b.

[0518] The second sun tooth 1130b is fixedly connected to the first planetary carrier 1121b, and multiple second planetary teeth 1132b are rotatably connected to the second planetary carrier 1131b. The multiple second planetary teeth 1132b are arranged circumferentially around the rotation center of the second sun tooth 1130b, and the multiple second planetary teeth 1132b respectively mesh with the second sun tooth 1130b and the internal gear ring 1141b.

[0519] The first output shaft 110b is fixedly connected to the second planetary carrier 1131b, and the axis of the first output shaft 110b is collinear with the rotation axis of the second planetary carrier 1131b. The second output shaft 111b passes through the second planetary carrier 1131b and is fixed coaxially with the second sun tooth 1130b.

[0520] When it is necessary to drive the second output shaft 111b to output the second speed, the drive member 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. At the same time, each of the first planetary gears 1122b can revolve around the first sun gear 1120b, thereby driving the first planetary carrier 1121b to rotate. At this time, the first planetary carrier 1121b can directly drive the second output shaft 111b to rotate through the second sun gear 1130b, thereby driving the second output shaft 111b to output the second speed.

[0521] When the first output shaft 110b needs to output a first rotational speed, the drive component 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. Simultaneously, each of the first planetary gears 1122b revolves around the first sun gear 1120b, thereby driving the first planet carrier 1121b and the second sun gear 1130b to rotate. The second sun gear 1130b, in conjunction with the internal gear ring 1141b, drives each of the second planetary gears 1132b to rotate around its own axis. Simultaneously, each of the second planetary gears 1132b revolves around the second sun gear 1130b, thereby driving the second planet carrier 1131b to rotate. At this time, the second planet carrier 1131b can directly drive the first output shaft 110b to rotate, thereby driving the first output shaft 110b to output the first rotational speed.

[0522] The two-stage planetary gear transmission structure drives the first output shaft 110b and the second output shaft 111b to output different speeds. The planetary gear transmission structure makes it easy to flexibly adjust the transmission ratio according to the output speed requirements. At the same time, each of the first planetary teeth 1122b and the second planetary teeth 1132b can evenly share the load of the drive component 12b, which is connected to the first output shaft 110b and the second output shaft 111b, so as to meet the requirements of larger torque transmission capacity and improve the ability to adapt to the requirements of higher output speed.

[0523] Furthermore, it is understandable that planetary gear transmission structures have high transmission stability. The meshing structure of planetary gears and sun gears reduces vibration and noise generated during transmission, thereby helping to reduce the noise generated during the operation of the roller brush.

[0524] In some embodiments, referring to Figures 20 and 21, the transmission mechanism 11b further includes multiple connecting portions 119b. The first output shaft 110b and the second output shaft 111b are respectively connected to at least one connecting portion 119b. The first output shaft 110b is detachably connected to the first roller brush 3b via the connecting portion 119b, and the second output shaft 111b is detachably connected to the second roller brush 4b via the connecting portion 119b. In this embodiment, taking the first output shaft 110b and the second output shaft 111b each having one connecting portion 119b as an example, the structure of the connecting portion 119b is adapted to the corresponding connecting structure within the first roller brush 3b and the second roller brush 4b, and can be fixed by snap-fit ​​or other means, which will not be elaborated further here. In other embodiments, the number of connecting portions 119b on the first output shaft 110b and the second output shaft 111b can be flexibly increased according to the structure of the roller brush and the required connection strength.

[0525] Through the independent connecting parts 119b, the first output shaft 110b and the second output shaft 111b and the corresponding first roller brush 3b and second roller brush 4b can be quickly disassembled and assembled. Different roller brushes and cleaning speeds can be adapted without changing different cleaning equipment, thus improving the convenience of cleaning.

[0526] Unlike the first roller brush 3b and the second roller brush 4b, which require different connecting parts 119b to be connected to the corresponding first output shaft 110b and second output shaft 111b, in some embodiments, referring to Figures 22 to 26, the transmission mechanism 11b also includes a first connector 116b and a second connector 117b. The first connector 116b is coaxially fixedly connected to the first end 1101b, and the second connector 117b is coaxially fixedly connected to the second end 1110b. The transmission mechanism 11b also includes a switching component 115b, which is movably disposed between the first output shaft 110b and the second output shaft 111b. The switching component 115b can be connected to the first roller brush 3b and the second roller brush 4b respectively: the first roller brush 3b is connected to the first output shaft 110b through the switching component 115b, and the second roller brush 4b is connected to the second output shaft 111b through the switching component 115b.

[0527] Specifically, referring to Figures 24 to 26, the switching assembly 115b includes a switching part 1150b and an elastic member 1155b. The switching part 1150b is slidably sleeved on the second output shaft 111b, and at least a portion of the switching part 1150b is located between the first end 1101b and the second end 1110b. The elastic member 1155b may be a spring and is sleeved on the second output shaft 111b. The elastic member 1155b connects the first coupling connector 116b and the switching part 1150b. The elastic member 1155b is configured to push against the switching part 1150b and drive the switching part 1150b to the second output shaft 111b. That is, when the switching part 1150b is installed on the second output shaft 111b, it is ensured that the elastic member 1155b abuts against the switching part 1150b in a state of no elastic deformation, and that the switching part 1150b remains connected to the second coupling connector 117b.

[0528] The switching part 1150b, the first roller brush 3b, and the second roller brush 4b can all adopt a tooth meshing structure. The first roller brush 3b and the second roller brush 4b are both provided with a tooth ring structure inside, and an external tooth structure is provided on the outer peripheral surface of the switching part 1150b. When the first roller brush 3b or the second roller brush 4b is sleeved on the switching part 1150b, the first roller brush 3b or the second roller brush 4b meshes with the external tooth structure on the outer peripheral surface of the switching part 1150b through the tooth ring structure, so as to realize the transmission connection between the two.

[0529] The switching unit 1150b has a first mating groove 1151b on the side facing the first mating connector 116b for at least a portion of the first mating connector 116b to be inserted. The first mating connector 116b is circumferentially provided with a plurality of first meshing teeth 1160b around the axis of the first output shaft 110b. The inner wall of the first mating groove 1151b is circumferentially provided with a plurality of first internal teeth 1153b around the axis of the first output shaft 110b. When at least a portion of the first mating connector 116b is inserted into the first mating groove 1151b, the plurality of first meshing teeth 1160b and the plurality of first internal teeth 1153b mesh with each other, thereby realizing the transmission connection between the switching unit 1150b and the first mating connector 116b.

[0530] The switching part 1150b has a second mating groove 1152b on the side facing the second mating joint 117b for at least a portion of the second mating joint 117b to be inserted. The second mating joint 117b is circumferentially provided with a plurality of second meshing teeth 1170b around the axis of the second output shaft 111b. The inner wall of the second mating groove 1152b is circumferentially provided with a plurality of second internal teeth 1154b around the axis of the second output shaft 111b. When at least a portion of the second mating joint 117b is inserted into the second mating groove 1152b, the plurality of second meshing teeth 1170b and the plurality of second internal teeth 1154b mesh with each other, thereby realizing the transmission connection between the switching part 1150b and the second mating joint 117b.

[0531] The elastic element 1155b provides a preset force for the switching part 1150b to connect to the second coupling 117b, which helps to maintain the transmission connection between the switching part 1150b and the second output shaft 111b, thereby improving the stability of the transmission connection between the switching part 1150b and the second output shaft 111b. It is understood that, based on this, when the first roller brush 3b is used to connect the switching part 1150b, the first roller brush 3b is pre-set with a push plate 30b structure that can push against the switching part 1150b and compress the elastic element 1155b. This push plate 30b structure is also provided with clearance holes 300b that allow the second coupling 117b and the second output shaft 111b to pass through, so as to avoid interference with the second coupling 117b and the second output shaft 111b.

[0532] A space is reserved between the first end 1101b and the second end 1110b for the switching part 1150b to slide. The switching part 1150b is sleeved on the second output shaft 111b, which improves the installation stability of the switching part 1150b. The second output shaft 111b serves as a guide structure to achieve a stable switching transmission position of the switching part 1150b, which is conducive to quickly realizing the transmission connection between the switching part 1150b and the first roller brush 3b or the second roller brush 4b. After the first mating joint 116b is embedded in the first mating groove 1151b, it achieves the transmission connection with the switching part 1150b through the meshing of the first meshing tooth 1160b and the first internal tooth 1153b. After the second mating joint 117b is embedded in the second mating groove 1152b, it achieves the transmission connection with the switching part 1150b through the meshing of the second meshing tooth 1170b and the second internal tooth 1154b. The first mating groove 1151b and the second mating groove 1152b, along with the toothed meshing transmission structure, improve the mating accuracy of the switching part 1150b and the first mating joint 116b and the second mating joint 117b. The first mating groove 1151b and the second mating groove 1152b limit the first mating joint 116b and the second mating joint 117b, thereby improving the transmission stability of the switching part 1150b and the first output shaft 110b and the second output shaft 111b. At the same time, the toothed meshing transmission structure helps to further improve the ability of the switching part 1150b and the first mating joint 116b and the second mating joint 117b to transmit larger torques.

[0533] It is understood that in other embodiments, the elastic element 1155b may also be connected between the second connector 117b and the switching part 1150b. When the first roller brush 3b is connected to the switching part 1150b, the elastic element 1155b can push against the switching part 1150b and drive the switching part 1150b to the first output shaft 110b. This helps to maintain the drive connection between the switching part 1150b and the first output shaft 110b, thereby improving the stability of the drive connection between the switching part 1150b and the first output shaft 110b.

[0534] Furthermore, in some embodiments, referring to Figures 24 to 26, the area of ​​the cross-section of the first connector 116b in the direction perpendicular to the axis of the first output shaft 110b increases from the end closer to the first mating groove 1151b to the end farther away from the first mating groove 1151b. A pre-set guide structure on the first connector 116b facilitates the rapid insertion of the end of the first connector 116b towards the first mating groove 1151b into the first mating groove 1151b, and gradually increases the tightness of the fit between the first connector 116b and the first mating groove 1151b as the first connector 116b is inserted into the first mating groove 1151b, thereby improving the docking accuracy and stability of the first connector 116b and the switching part 1150b.

[0535] In some embodiments, referring to Figures 24 to 26, the area of ​​the cross-section of the second connector 117b in the direction perpendicular to the axis of the second output shaft 111b decreases from the end near the second mating groove 1152b to the end away from the second mating groove 1152b. A pre-set guide structure on the second connector 117b facilitates the rapid insertion of the end of the second connector 117b towards the second mating groove 1152b into the second mating groove 1152b, and gradually increases the tightness of the fit between the second connector 117b and the second mating groove 1152b as the second connector 117b is inserted into the second mating groove 1152b, thereby improving the docking accuracy and stability of the second connector 117b and the switching part 1150b.

[0536] Furthermore, in some embodiments, referring to Figures 24 and 25, at least one of the first connector 116b and the switching part 1150b has a receiving groove 118b facing the elastic member 1155b, and a portion of the elastic member 1155b is embedded in the receiving groove 118b. In this embodiment, the receiving groove 118b is provided in the first connector 116b as an example. In other embodiments, the receiving groove 118b may also be provided in the switching part 1150b, or both the first connector 116b and the switching part 1150b; further details will not be provided here.

[0537] The receiving groove 118b helps to provide an installation reference for the elastic element 1155b, improving the installation stability of the elastic element 1155b. At the same time, the receiving groove 118b can provide a guiding and limiting function during the elastic deformation of the elastic element 1155b, improving the stability of the elastic element 1155b during the elastic deformation process, and reducing the problem of the elastic element 1155b interfering with other structures.

[0538] Accordingly, a floor brush assembly according to an embodiment of this application includes a floor brush base 2b, the aforementioned multi-stage roller brush drive device 1b, and a first roller brush 3b and a second roller brush 4b. The floor brush base 2b can move along the surface to be cleaned according to a preset travel direction, and at the same time, the multi-stage roller brush drive device 1b drives the connected first roller brush 3b or second roller brush 4b to roll and clean the surface to be cleaned.

[0539] The floor brush base 2b has a receiving cavity 20b, and the multi-stage roller brush drive device 1b is disposed in the receiving cavity 20b and connected to the floor brush base 2b. A first roller brush 3b and a second roller brush 4b are respectively disposed in the receiving cavity 20b and rotatably connected to the floor brush base 2b. The first roller brush 3b is driven by the first output shaft 110b of the multi-stage roller brush drive device 1b, so that the multi-stage roller brush drive device 1b drives the first roller brush 3b to rotate via the first output shaft 110b. The second roller brush 4b is driven by the second output shaft 111b of the multi-stage roller brush drive device 1b, so that the multi-stage roller brush drive device 1b drives the second roller brush 4b to rotate via the second output shaft 111b.

[0540] In some embodiments, the floor brush assembly further includes a liquid pump, a liquid dispensing component, a first sensor, and a second sensor. The liquid pump and the liquid dispensing component are respectively disposed on the floor brush base 2b. The liquid pump is configured to pump liquid to the liquid dispensing component, and the liquid dispensing component is used to spray liquid toward the first roller brush 3b. The first sensor can be disposed on the first roller brush 3b or the second roller brush 4b, and the second sensor is disposed on the floor brush base 2b. The first and second sensors are capable of generating sensing signals. It is understood that a controller can also be installed on the floor brush base 2b to receive the sensing signals; the principle of its sensing communication is prior art and will not be described in detail here.

[0541] Taking the first sensor installed on the first roller brush 3b as an example:

[0542] When the floor brush assembly needs to perform wet cleaning on the floor surface to be cleaned, the first roller brush 3b is used. At this time, the first output shaft 110b is connected to the first roller brush 3b, driving it to clean the surface at a first rotational speed. The controller can receive the sensing signals generated by the first and second sensors. The controller can then control the liquid pump to turn on and draw liquid to deliver it to the dispensing component, causing the liquid to spray towards the first roller brush 3b. The dispensing component wets the first roller brush 3b, thus wet cleaning the surface.

[0543] When the floor brush assembly needs to perform vacuuming only on the carpet or other surfaces awaiting cleaning, the second roller brush 4b is used. In this case, the second output shaft 111b is connected to the second roller brush 4b, driving it to clean the surface at a second rotational speed. If the controller does not receive the sensing signals from the first and second sensors, it shuts off the liquid pump, allowing the second roller brush 4b to assist in cleaning the surface during vacuuming only.

[0544] It is understandable that, taking the second roller brush 4b as an example, the first sensor is installed:

[0545] When the floor brush assembly needs to perform wet cleaning on the floor surface to be cleaned, the first roller brush 3b is used. At this time, the first output shaft 110b is connected to the first roller brush 3b to drive the first roller brush 3b to clean the surface to be cleaned at a first rotation speed. If the controller does not receive the sensing signals generated by the first and second sensors, the controller can control the liquid pump to turn on and draw liquid to deliver to the dispensing component, so that the dispensing component sprays liquid toward the first roller brush 3b. The dispensing component can wet the first roller brush 3b, thereby wet cleaning the surface to be cleaned through the first roller brush 3b.

[0546] When the floor brush assembly needs to perform vacuuming only on the carpet or other surfaces awaiting cleaning, the second roller brush 4b is used. In this case, the second output shaft 111b is connected to the second roller brush 4b, driving it to clean the surface at a second rotational speed. The controller receives the sensing signals generated by the first and second sensors. At this point, the controller shuts off the liquid pump, allowing the second roller brush 4b to assist in cleaning the surface during vacuuming only.

[0547] During the cleaning process using the floor brush assembly, the first and second sensors work together to generate a sensing signal. This signal allows for quick identification of the type of roller brush being used, facilitating the rapid switching of the floor brush base 2b to different cleaning modes for different roller brush types. This convenient, quick, and flexible switching between different roller brushes eliminates the need to change cleaning equipment to use the appropriate cleaning mode, significantly improving the ease of cleaning operations.

[0548] Accordingly, a cleaning device according to an embodiment of this application includes a body 5b and the aforementioned floor brush assembly, wherein the body 5b is rotatably connected to the floor brush assembly.

[0549] Unlike the aforementioned controller located on the brush base 2b, in some embodiments, a control device may be installed on the cleaning equipment, which can be mounted on the body 5b. The control device is communicatively connected to at least one of a first sensor and a second sensor on the brush assembly to receive sensing signals generated by the first sensor and / or the second sensor. Simultaneously, the control device is communicatively connected to a liquid pump on the brush assembly.

[0550] Understandably, when using cleaning equipment, the floor brush assembly can select either the first roller brush 3b or the second roller brush 4b according to the type of surface to be cleaned and the corresponding required rotation speed. The first roller brush 3b is driven by the first output shaft 110b to drive the first roller brush 3b to clean the surface to be cleaned at a first rotation speed, and the second roller brush 4b is driven by the second output shaft 111b to drive the second roller brush 4b to clean the surface to be cleaned at a second rotation speed. The control device can receive the sensing signal generated by the cooperation of the first and second sensors to quickly confirm the type of roller brush used. When it is confirmed that the floor brush assembly is using the second roller brush 4b, the control device can control the liquid pump to stop pumping liquid, so that the second roller brush 4b is in a suitable working environment, such as vacuuming, cleaning carpets, etc. When it is confirmed that the floor brush assembly is using the first roller brush 3b, the control device can control the liquid pump to pump liquid, so that the first roller brush 3b is in a suitable working environment, such as wet cleaning the surface to be cleaned. During the cleaning process, by holding the handheld device 5b, the floor brush assembly is moved along the surface to be cleaned in the preset direction. The surface can be cleaned by the first roller brush 3b or the second roller brush 4b. Only different roller brushes need to be flexibly changed, without the need to change different cleaning equipment, which improves the convenience of cleaning operations.

[0551] Accordingly, a cleaning system according to an embodiment of this application includes the aforementioned cleaning equipment and a base adapted to the cleaning equipment. It is understood that in some embodiments, the cleaning equipment further includes a clean liquid tank and a dirty liquid tank, wherein the clean liquid tank is used to store the cleaning liquid source to be used, and the dirty liquid tank is used to store the dirty liquid generated after cleaning.

[0552] When using a base station compatible with the cleaning equipment, the base station can provide functions such as supplying liquid to the cleaning liquid tank, draining the dirty liquid tank, self-cleaning the first roller brush 3b and the second roller brush 4b, drying the cleaning equipment, and charging the cleaning equipment.

[0553] The technical solutions provided in the embodiments of this application will be described below with reference to specific examples.

[0554] Example 1:

[0555] The multi-stage roller brush drive device 1b includes a base frame 10b, a transmission mechanism 11b, and a drive component 12b. The transmission mechanism 11b includes a housing 114b, a first output shaft 110b, a second output shaft 111b, a first planetary gear set 112b, a second planetary gear set 113b, and two connecting parts 119b.

[0556] A housing 114b is disposed within a base frame 10b, and the housing 114b has a transmission cavity 1140b and an opening facing the main body 100b. A first output shaft 110b is rotatably connected to the housing 114b, and portions of the first output shaft 110b and the second output shaft 111b both pass through the transmission cavity 1140b. An internal gear ring 1141b is provided on the inner wall of the transmission cavity 1140b surrounding the axis of the first output shaft 110b. A drive member 12b is mounted on the housing 114b, and the drive end 120b of the drive member 12b extends into the transmission cavity 1140b. A first planetary gear set 112b and a second planetary gear set 113b are sequentially arranged in the transmission cavity 1140b along the axial direction of the first output shaft 110b.

[0557] The first planetary gear set 112b includes a first sun gear 1120b, multiple first planetary gears 1122b, and a first planetary carrier 1121b. The first sun gear 1120b and the first planetary gears 1122b are respectively located on the side of the first planetary carrier 1121b facing the drive member 12b. The first sun gear 1120b is connected to the drive end 120b, and the connection end of the first sun gear 1120b and the drive end 120b constitutes a power input end. The multiple first planetary gears 1122b are rotatably connected to the first planetary carrier 1121b, and the multiple first planetary gears 1122b are circumferentially arranged around the rotation center of the first sun gear 1120b. The multiple first planetary gears 1122b respectively mesh with the first sun gear 1120b and the internal gear ring 1141b.

[0558] The second planetary gear set 113b includes a second sun gear 1130b, multiple second planetary gears 1132b, and a second planetary carrier 1131b. The second sun gear 1130b and the second planetary gears 1132b are respectively located on the side of the second planetary carrier 1131b facing the first planetary carrier 1121b. The second sun gear 1130b is fixedly connected to the first planetary carrier 1121b, and the multiple second planetary gears 1132b are rotatably connected to the second planetary carrier 1131b. The multiple second planetary gears 1132b are circumferentially arranged around the rotation center of the second sun gear 1130b, and the multiple second planetary gears 1132b respectively mesh with the second sun gear 1130b and the internal gear ring 1141b. The first output shaft 110b is fixedly connected to the second planetary carrier 1131b, and the axis of the first output shaft 110b is collinear with the rotation axis of the second planetary carrier 1131b. The second output shaft 111b passes through the second planetary carrier 1131b and is fixed coaxially with the second sun gear 1130b.

[0559] The first output shaft 110b and the second output shaft 111b are respectively connected to a connecting part 119b. The first output shaft 110b is detachably connected to the first roller brush 3b through the connecting part 119b, and the second output shaft 111b is detachably connected to the second roller brush 4b through the connecting part 119b.

[0560] When wet cleaning of the surface to be cleaned is required, the first roller brush 3b is selected and used. The first roller brush 3b is connected to the first output shaft 110b through the connection part 119b. When the first output shaft 110b needs to output the first rotational speed, the drive component 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. At the same time, each of the first planetary gears 1122b can revolve around the first sun gear 1120b, thereby driving the first planetary carrier 1121b and the second sun gear 1130b to rotate. The second sun gear 1130b, in conjunction with the internal gear ring 1141b, drives each of the second planetary gears 1132b to rotate around its own axis. At the same time, each of the second planetary gears 1132b can revolve around the second sun gear 1130b, thereby driving the second planetary carrier 1131b to rotate. At this time, the second planetary carrier 1131b can directly drive the first output shaft 110b to rotate, thereby driving the first output shaft 110b to output the first rotational speed, so that the first roller brush 3b performs wet cleaning operation at the first rotational speed.

[0561] When only vacuuming is required on the surface to be cleaned, the second roller brush 4b is selected. The second roller brush 4b is connected to the second output shaft 111b via the connecting part 119b. At this time, the second output shaft 111b needs to be driven to output a second speed. The driving member 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. At the same time, each of the first planetary gears 1122b can revolve around the first sun gear 1120b, thereby driving the first planetary carrier 1121b to rotate. The first planetary carrier 1121b can directly drive the second output shaft 111b to rotate via the second sun gear 1130b, thereby driving the second output shaft 111b to output a second speed, so that the second roller brush 4b assists the vacuuming operation at the second speed.

[0562] Example 2:

[0563] The difference between the multi-stage roller brush drive device 1b in this embodiment and the first embodiment is that the two connecting parts 119b are not used, but instead a switching component 115b and a matching first connector and second connector are used.

[0564] The first connector 116b is coaxially fixedly connected to the first end 1101b, and the second connector 117b is coaxially fixedly connected to the second end 1110b. The switching assembly 115b includes a switching part 1150b and an elastic element 1155b. The switching part 1150b is slidably sleeved on the second output shaft 111b, and at least a portion of the switching part 1150b is located between the first end 1101b and the second end 1110b. The elastic element 1155b is sleeved on the second output shaft 111b and connects the first connector 116b and the switching part 1150b.

[0565] The switching part 1150b has a first mating groove 1151b on the side facing the first mating connector 116b for at least a portion of the first mating connector 116b to be inserted. The first mating connector 116b is circumferentially provided with a plurality of first meshing teeth 1160b around the axis of the first output shaft 110b. The inner wall of the first mating groove 1151b is circumferentially provided with a plurality of first internal teeth 1153b around the axis of the first output shaft 110b.

[0566] The switching part 1150b has a second mating groove 1152b on the side facing the second mating connector 117b for at least a portion of the second mating connector 117b to be inserted. The second mating connector 117b is provided with a plurality of second meshing teeth 1170b circumferentially around the axis of the second output shaft 111b. The inner wall of the second mating groove 1152b is provided with a plurality of second internal teeth 1154b circumferentially around the axis of the second output shaft 111b.

[0567] When wet cleaning of the surface to be cleaned is required, the first roller brush 3b is selected. The push plate 30b structure of the first roller brush 3b compresses the elastic element 1155b and connects the switching part 1150b to the first connector 116b. When the first output shaft 110b needs to output the first rotational speed, the drive component 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. At the same time, each of the first planetary gears 1122b can revolve around the first sun gear 1120b, thereby driving the first planetary carrier 1121b and the second sun gear 1130b to rotate. The second sun gear 1130b, in conjunction with the internal gear ring 1141b, drives each of the second planetary gears 1132b to rotate around its own axis. At the same time, each of the second planetary gears 1132b can revolve around the second sun gear 1130b, thereby driving the second planetary carrier 1131b to rotate. At this time, the second planetary carrier 1131b can directly drive the first output shaft 110b to rotate, thereby driving the first output shaft 110b to output the first rotational speed, so that the first roller brush 3b performs wet cleaning operation at the first rotational speed.

[0568] When only vacuuming is required on the surface to be cleaned, the second roller brush 4b is selected. When the second roller brush 4b is connected to the switching part 1150b, the elastic element 1155b pushes the switching part 1150b to connect to the second coupling connector 117b. At this time, the second output shaft 111b needs to be driven to output a second speed. The driving element 12b drives the first sun gear 1120b to rotate. The first sun gear 1120b, in conjunction with the internal gear ring 1141b, drives each of the first planetary gears 1122b to rotate around its own axis. At the same time, each of the first planetary gears 1122b can revolve around the first sun gear 1120b, thereby driving the first planetary carrier 1121b to rotate. The first planetary carrier 1121b can directly drive the second output shaft 111b to rotate through the second sun gear 1130b, thereby driving the second output shaft 111b to output a second speed, so that the second roller brush 4b assists the vacuuming operation at the second speed.

[0569] Example 3:

[0570] The floor brush assembly can be applied to cleaning equipment such as floor scrubbers. The floor brush assembly includes a floor brush base 2b, a multi-stage roller brush drive device 1b as shown in Embodiment 1 or Embodiment 2, and a first roller brush 3b and a second roller brush 4b. The floor brush assembly also includes a liquid pump, a liquid dispensing component, a first sensor, a second sensor, and a controller. The second sensor and the controller are located on the floor brush base 2b, and the first sensor is located on the first roller brush 3b.

[0571] The floor brush base 2b can move along the surface to be cleaned in a preset direction. When the floor brush assembly needs to perform wet cleaning on the floor surface, the first roller brush 3b is used. At this time, the first output shaft 110b is connected to the first roller brush 3b to drive the first roller brush 3b to clean the surface at a first rotation speed. The controller can receive the sensing signals generated by the first and second sensors. At this time, the controller can control the liquid pump to turn on and draw liquid to deliver to the dispensing component, so that the dispensing component sprays liquid toward the first roller brush 3b. The dispensing component can wet the first roller brush 3b, thereby wet cleaning the surface to be cleaned by the first roller brush 3b.

[0572] When the floor brush assembly needs to perform vacuuming only on the carpet or other surfaces awaiting cleaning, the second roller brush 4b is used. In this case, the second output shaft 111b is connected to the second roller brush 4b, driving it to clean the surface at a second rotational speed. If the controller does not receive the sensing signals from the first and second sensors, it shuts off the liquid pump, allowing the second roller brush 4b to assist in cleaning the surface during vacuuming only.

[0573] Example 4:

[0574] The cleaning equipment is a floor scrubber. It includes a body 5b and a floor brush assembly similar to that in Embodiment 3, with the body 5b rotatably connected to the floor brush assembly. It also includes a clean liquid tank and a dirty liquid tank located on the body 5b. The clean liquid tank stores the cleaning liquid to be used, and the dirty liquid tank stores the dirty liquid generated after cleaning. The difference is that a control device is provided on the body 5b. The control device is communicatively connected to at least one of a first sensor and a second sensor on the floor brush assembly to receive sensing signals generated by the first sensor and / or the second sensor. Simultaneously, the control device is communicatively connected to a liquid pump on the floor brush assembly.

[0575] When using the cleaning equipment, the floor brush assembly can select either the first roller brush 3b or the second roller brush 4b according to the type of surface to be cleaned and the corresponding required rotation speed. The first roller brush 3b is driven by the first output shaft 110b to drive the first roller brush 3b to clean the surface to be cleaned at the first rotation speed, and the second roller brush 4b is driven by the second output shaft 111b to drive the second roller brush 4b to clean the surface to be cleaned at the second rotation speed. The control device receives the sensing signal generated by the cooperation of the first and second sensors to quickly determine the type of roller brush used.

[0576] When the floor brush assembly is confirmed to be using the second roller brush 4b, the control device can control the liquid pump to stop pumping liquid, thereby placing the second roller brush 4b in a suitable working environment, such as vacuuming, cleaning carpets, or cleaning surfaces. At this time, the dust and other impurities sucked up can be collected into the waste liquid tank.

[0577] When the first roller brush 3b is confirmed to be used in the floor brush assembly, the control device can control the liquid pump to pump the liquid in the cleaning tank, so that the first roller brush 3b is in a suitable working environment, such as wet cleaning of the surface to be cleaned.

[0578] During the cleaning process, by holding the handheld device 5b, the floor brush assembly is moved along the surface to be cleaned in the preset direction. The surface can be cleaned by the first roller brush 3b or the second roller brush 4b. Only different roller brushes need to be flexibly changed, without the need to change different cleaning equipment, which improves the convenience of cleaning operations.

[0579] Example 5:

[0580] The cleaning system includes a cleaning device as described in Example 4 and a base adapted to the cleaning device.

[0581] Before using the cleaning equipment, place it inside the base. The base will charge the cleaning equipment and replenish the cleaning solution tank.

[0582] After cleaning is completed, the cleaning equipment can be placed in the base. The base charges the cleaning equipment and replenishes the cleaning liquid in the cleaning liquid tank and drains the dirty liquid tank. In addition, the first roller brush 3b or the second roller brush 4b can be self-cleaned and dried in the base after use.

[0583] The foregoing has provided a detailed description of a multi-stage roller brush drive device, floor brush assembly, cleaning equipment, and cleaning system provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.

[0584] Please refer to Figures 27 to 29. One embodiment of this application provides a cleaning device 200c, which includes a main body 201c and a floor brush device 100c, which are connected via a recycling channel 41c. The floor brush device 100c includes a roller brush 10c, a drive assembly 20c, and a spray assembly 30c. The drive assembly 20c includes a drive member 21c and a housing 22c. The housing 22c covers the drive member 21c, and the roller brush 10c is covered by the housing 22c. The drive member 21c connects to and drives the roller brush 10c to rotate. The drive member 21c is driveably connected to the roller brush 10c to operate at least at a first speed and a second speed, wherein the first speed is greater than the second speed. At least a portion of the spray assembly 30c is disposed within the floor brush device 100c. The spray assembly 30c includes an air intake channel 33c and a nozzle (not shown in the figure). The nozzle is located within a recovery channel 41c. The air intake port 334c of the air intake channel 33c is disposed within the housing 22c. The spray assembly 30c is used to generate airflow disturbance between the roller brush 10c and the housing 22c during the rotation of the roller brush 10c by the drive assembly 20c. It should be noted that the roller brush 10c is not limited to operating at the first and second speeds, and can be operated at other different speeds by the drive member 21c or other components according to actual design requirements.

[0585] In this embodiment, the cleaning device 200c may include a vacuuming mode and a floor washing mode. In the vacuuming mode, the drive unit 21c drives the roller brush 10c to rotate at a first speed. When the drive unit 21c is in the floor washing mode, it drives the roller brush 10c to run at a second speed. The first speed is greater than the second speed, and the water content of the roller brush 10c in the vacuuming mode is less than the water content of the roller brush 10c in the floor washing mode.

[0586] Understandably, the rotational speed of the drive component 21c of the floor brush device differs between vacuuming and washing modes, resulting in different cleaning effects for the cleaning device 200c. The floor brush device can switch between a first and a second rotational speed (i.e., vacuuming and washing modes). When the drive component 21c rotates at the first speed, the higher speed causes its temperature to rise. Simultaneously, the spray component 30c needs to humidify the dust sucked into the recovery channel 41c during vacuuming mode to improve the vacuuming efficiency of the cleaning device 200c. In other words, adding a vacuuming mode increases the need for dust humidification and the high-speed rotation of the drive component 21c. The high-speed rotation of the drive component 21c can cause the housing 22c to overheat. Furthermore, users need to manually remove and replace the wet roller brush when the cleaning device 200c is in different modes to ensure effective cleaning. During this process, the spray assembly 30c can generate airflow disturbance between the roller brush 10c and the housing 22c through the air intake channel 33c to cool the housing 22c, thereby preventing the risk of the user accidentally touching the housing 22c and getting burned.

[0587] It should be noted that, in this embodiment, by designing the spray assembly 30c and rationally setting the positions of the air intake channel 33c and nozzles, the needs for humidifying the dust in the recovery channel 41c and cooling the drive assembly 20c generated after the cleaning device 200c adds a dust suction mode can be simultaneously addressed. In this embodiment, the spray assembly 30c can agitate the air in the space between the roller brush 10c and the housing 22c, thereby removing heat from the drive assembly 20c. Thus, on the one hand, the spray assembly 30c can humidify the dust entering the recovery channel 41c through the nozzles, improving the working efficiency of the cleaning device 200c; on the other hand, the spray assembly 30c can generate airflow agitation between the roller brush 10c and the housing 22c through the air intake channel 33c to remove heat from the vicinity of the housing 22c, thereby cooling the housing 22c and preventing the housing 22c from overheating and causing burns to the user's hands.

[0588] In this embodiment, the spray assembly 30c includes an air pump 31c and an air inlet pipe 32c, with the air pump 31c connected to the air inlet channel 33c via the air inlet pipe 32c.

[0589] In this embodiment, the floor brush device 100c can switch between vacuuming mode and floor washing mode (i.e., dry cleaning and wet cleaning). In vacuuming mode, the temperature of the drive component 21c increases, and the spray component 30c can agitate the air in the space between the roller brush 10c and the housing 22c, thereby removing the heat from the drive component 20c. This not only cools the drive component 20c and improves its working efficiency, but also prevents the housing 22c from overheating and causing accidental burns when the user needs to replace the roller brush 10c.

[0590] It should be noted that because wet and dry cleaning surfaces differ, the required rotational speed of the roller brush 10c also differs (i.e., the first rotational speed is greater than the second). In vacuuming mode, the drive unit 21c drives the roller brush 10c to rotate at the first rotational speed, which is relatively high and causes the temperature of the drive unit 21c and the housing 22c to rise. After vacuuming, users often switch the floor brush device 100c to floor washing mode. At this time, the user needs to manually replace the roller brush 10c, exposing the housing 22c to heat, posing a risk of burns and resulting in a poor user experience and safety issues.

[0591] The floor brush device 100c of this application embodiment includes an air pump 31c and an air inlet channel 33c. The air inlet channel 33c provides air to the air pump 31c and generates airflow disturbance between the roller brush 10c and the housing 22c. In other words, the floor brush device 100c of this application embodiment simultaneously solves the problems of air intake of the air pump 31c and heat dissipation of the housing 22c.

[0592] In this embodiment, the spray component 30c can be the air pump 31c already present in the floor brush device 100c. The spray component 30c generates airflow disturbance between the roller brush 10c and the housing 22c through the air intake channel 33c. Thus, without adding any additional structural components, cooling of the drive component 20c can be achieved simply by designing the position of the air intake channel 33c. In this embodiment, the air pump 31c itself has the function of atomizing the dust after suction. This embodiment redesigns the air intake channel 33c of the air pump 31c, so that while atomizing the air it draws in, it also cools the housing 22c by drawing in hot air, thereby achieving reuse of the spray component 30c and making the floor brush device 100c perform better and more comprehensively.

[0593] In this embodiment, the air inlet 334c is disposed on the outer surface of the housing 22c facing the roller brush 10c.

[0594] It is understood that, in the embodiments of the application, the spray assembly 30c can generate airflow disturbance between the roller brush 10c and the housing 22c, and its specific form is not limited to meet different needs. For example, the spray assembly 30c can be an air pump 31c, and the air inlet 334c of the air pump 31c can be set between the roller brush 10c and the housing 22c, thereby blowing air to dissipate heat in the space between the roller brush 10c and the housing 22c during the operation of the air pump 31c. In this document, the air inlet 334c is used to dissipate heat in the space between the roller brush 10c and the housing 22c, and the specific details will not be repeated.

[0595] In this embodiment, the spray assembly 30c and the floor brush device 100c are in different modes. That is, the spray assembly 30c can be activated when the floor brush device 100c is in vacuuming mode or floor washing mode to dissipate heat from the space between the roller brush 10c and the housing 22c.

[0596] In this embodiment, the spray assembly 30c humidifies the dust collected in the dust collection chamber and also dissipates heat from the space between the roller brush 10c and the housing 22c. By reusing the spray assembly 30c, its air intake channel 33c is positioned between the housing 22c and the roller brush 10c to draw air from the space between them, thereby removing heat from the drive assembly 20c. This also prevents the housing 22c from overheating and causing accidental burns when the user needs to replace the roller brush 10c.

[0597] Specifically, the drive assembly 20c includes a drive member 21c and a housing 22c. The housing 22c covers the drive member 21c, and the roller brush 10c covers the housing 22c. The drive member 21c is a motor used to drive the roller brush 10c to rotate for cleaning the floor. The drive member 21c can rotate about a central axis within the housing 22c. At least a portion of the structure of the drive member 21c can extend outside the housing 22c. The roller brush 10c can be connected to the portion of the drive member 21c that extends outside the housing 22c via a locking structure (not shown in the figure). In this way, the drive member 21c can drive the roller brush 10c to rotate around the housing 22c. The locking structure is detachable. When the roller brush 10c needs to be replaced, the locking structure can be opened to remove the roller brush 10c from the drive assembly 20c for replacement.

[0598] Furthermore, in this embodiment, the specific type of the roller brush 10c is not limited to meet different needs. For example, the roller brush 10c may include a rubber tube and a flocking component, which facilitates the roller brush 10c to rotate under the drive of the drive component 21c after being moistened to clean the floor.

[0599] Furthermore, referring to Figure 30, there is a certain gap between the roller brush 10c covering the housing 22c and the housing 22c, preferably about 1mm. This reduces unnecessary friction between the two and also provides sufficient suction space for the air intake channel 33c of the spray assembly 30c, preventing the roller brush 10c from blocking the air intake port 334c.

[0600] In this embodiment, when the roller brush 10c consists of a rubber tube and a flocked component, the flocked component can absorb water and moisten it to clean the ground, while the rubber tube prevents water from entering the gap between the roller brush 10c and the housing 22c, thus affecting the operation of the spray assembly 30c. Of course, in some embodiments, a dedicated waterproof gasket can be provided between the roller brush 10c and the housing 22c, with a gap space between the waterproof gasket and the housing 22c for air extraction. The waterproof gasket prevents water from the roller brush 10c or the ground from entering this gap space.

[0601] In some embodiments, the floor brush device 100c includes a vacuuming mode and a washing mode. For example, in the vacuuming mode, the dust drawn in can become airborne inside the floor brush device 100c, easily causing pollution. In this case, the spray assembly 30c can draw in and pressurize gas through the air intake channel 33c to form high-pressure gas. The high-pressure gas then atomizes and pressurizes water before spraying it out, thereby humidifying the drawn-in dust and preventing dust from flying inside the floor brush device 100c and causing pipe blockage or other pollution.

[0602] Specifically, the floor brush device 100c may also include a water pump assembly (not shown in the figure), which, together with the spray assembly 30c, can wet the sucked-in dust to prevent dust from accumulating at the filter element (not shown in the figure) before the vacuum pump (not shown in the figure), causing the filter element to become clogged and affecting the working efficiency of the vacuum pump.

[0603] Furthermore, the vacuuming mode requires the drive component 20c to operate at a higher speed (e.g., 1200 rpm), resulting in a higher load and more heat generation. Simultaneously, the vacuuming mode reduces the water content of the roller brush 10c, weakening the heat dissipation capacity of the drive component 20c, further increasing its heat generation and causing the housing 22c to overheat. In this situation, if the user needs to replace the roller brush 10c, they are easily burned by the housing 22c. In this embodiment, the air intake channel 33c of the spray component 30c can be positioned in the gap between the roller brush 10c and the housing 22c. Utilizing the principle that the spray component 30c needs to draw in gas when atomizing and pressurizing water, the air intake channel 33c can draw away the hot gas between the roller brush 10c and the housing 22c.

[0604] Of course, the spray assembly 30c can also operate in other modes. This embodiment does not limit the operating time of the spray assembly 30c to meet various needs. Thus, by reusing the spray assembly 30c, its air intake channel 33c is positioned between the housing 22c and the roller brush 10c, allowing air to be drawn from the space between the roller brush 10c and the housing 22c, thereby removing the heat generated by the drive assembly 20c and preventing overheating. In this way, if the user accidentally touches the drive assembly 20c when the roller brush 10c needs to be replaced, the lower-temperature housing 22c will not burn the user. Thus, without adding any additional components, a better user experience can be provided.

[0605] Furthermore, when the floor brush device 100c is in vacuum mode, the spray component 30c atomizes and pressurizes water and sprays water mist to moisten the dust, while also cooling the inhaled hot air, which can prevent heat accumulation inside the floor brush device 100c and thus ensure the performance of the floor brush device 100c.

[0606] Additionally, the floor washing mode can be a floor washing mode, which requires a lower rotation speed of the drive unit 21c and a higher water content of the roller brush 10c. This application embodiment does not limit the specific mode setting of the floor brush device 100c. For example, it may also have a third mode, which can be a combination of vacuuming and floor washing modes. Furthermore, more different power levels and modes can be set to meet various cleaning needs.

[0607] Please refer to Figures 31 and 32. In some embodiments, the spray assembly 30c further includes an air pump 31c and an air intake pipe 32c, the air pump 31c being connected to the air intake passage 33c via the air intake pipe 32c.

[0608] In this way, the continuous pipelines and channels can create a negative pressure inside the spray assembly 30c, allowing the airflow to be smoothly transmitted to the gap between the roller brush 10c and the housing 22c, drawing away the hot gas between the roller brush 10c and the housing 22c, and dissipating heat for the drive assembly 20c.

[0609] Specifically, the air pump 31c is connected to the intake pipe 32c and then to the intake channel 33c. When the air pump 31c is working, it will generate a negative pressure and transfer the negative pressure to the intake pipe 32c connected to the air pump 31c, so that a negative pressure is formed in the intake pipe 32c. The negative pressure in the intake pipe 32c is then transferred to the intake channel 33c connected to the other end of the intake pipe 32c, so that the intake channel 33c has a negative pressure suction force, thereby drawing in the hot gas between the roller brush 10c and the housing 22c at the other end of the intake channel 33c, so as to dissipate heat from the drive component 20c.

[0610] Please refer to Figures 27, 31, and 32. In some embodiments, the air inlet 334c is disposed on the outer surface of the housing 22c facing the roller brush 10c.

[0611] In this way, the position of the air inlet 334c is fixed, and the position of the air intake channel 33c is also fixed. The air inlet 334c is set on the outer surface of the housing 22c facing the roller brush 10c, which can generate airflow at the gap between the housing 22c and the roller brush 10c. During the process of the airflow entering the air inlet 334c, the housing 22c can be cooled.

[0612] Specifically, the housing 22c can be made of a harder material that is more resistant to high temperatures and less prone to deformation (such as metal, ceramic or composite materials). This is beneficial to increasing the airtightness of the intake channel 33c and the service life of the housing 22c, and to facilitating the removal of hot gas between the roller brush 10c and the housing 22c, so as to dissipate heat for the drive component 20c.

[0613] Furthermore, the air inlet 334c and part of the air intake channel 33c can be set on the housing 22c, which is prone to overheating in the drive component 20c, so that the spray component 30c can efficiently dissipate heat from the drive component 20c.

[0614] In the embodiments of this application, the size of the air inlet 334c is sufficient to meet the air intake volume, and no specific limitation is made here.

[0615] Please refer to Figures 28, 29, 32, and 33 together. In some embodiments, the floor brush device 100c further includes a floor brush body 40c and a suspension bracket 50c, the floor brush body 40c being connected to the drive assembly 20c via the suspension bracket 50c; the air pump 31c of the spray assembly 30c is located inside the floor brush body 40c, and at least a portion of the air intake channel 33c is located inside the suspension bracket 50c.

[0616] In this way, the brush body 40c, the suspension bracket 50c and the drive component 20c are connected together. The various parts of the spray component 30c are set in the three components of the brush device 100c. Heat dissipation of the drive component 20c can be achieved without adding extra air channels, thus increasing the aesthetics of the brush device 100c.

[0617] For example, the brush body 40c is connected to one end of the suspension bracket 50c, and the other end of the suspension bracket 50c is connected to the outside of the drive assembly 20c. Meanwhile, the air inlet 334c of the air intake channel 33c is located on the outer side of the surface of the housing 22c (i.e., near the suspension bracket 50c). At least a portion of the air intake channel 33c leads into the housing 22c, then bends and extends from the housing 22c into the suspension bracket 50c. The air intake channel 33c within the suspension bracket 50c then bends and extends back to the brush body 40c, thus allowing the air inlet 334c to connect from the air intake channel 33c to the air pump 31c located within the brush body 40c. This facilitates the transfer of the negative pressure generated when the air pump 31c operates through the air intake channel 33c to the air inlet 334c, thereby drawing away the hot gas accumulated between the roller brush 10c and the housing 22c and dissipating heat from the drive assembly 20c.

[0618] In addition, the roller brush 10c can move up and down vertically under the action of the suspension bracket 50c to enhance the cleaning performance of the floor brush device 100c and facilitate the floor brush device 100c to clean the gaps between floor tiles and scattered foreign objects on the ground.

[0619] Please refer to Figures 31 and 32 together. In some embodiments, the air intake passage 33c further includes: a first air intake section 331c, a second air intake section 332c, and a third air intake section 333c connected in sequence;

[0620] The first air intake section 331c is connected to the air intake 334c and passes through the suspension bracket 50c; the second air intake section 332c is installed inside the suspension bracket 50c of the floor brush device 100c; the third air intake section 333c passes through the suspension bracket 50c and is connected to the air pump 31c and the second air intake section 332c.

[0621] Thus, the air intake channel 33c connects the air intake port 334c and the air pump 31c, making it easier for the air pump 31c to draw in air and dissipate heat through the air intake port 334c.

[0622] Specifically, the air inlet 334c is connected to one end of the first air intake section 331c, and the other end of the first air intake section 331c extends and bends through the suspension bracket 50c. The end of the first air intake section 331c that passes through the suspension bracket 50c is connected to one end of the second air intake section 332c located within the suspension bracket 50c. The other end of the second air intake section 332c located within the suspension bracket 50c is connected to one end of the third air intake section 333c that passes through the suspension bracket 50c. The other end of the third air intake section 333c is then connected to the air pump 31c. In this way, the air intake channel 33c connects the air inlet 334c and the air pump 31c, facilitating the air pump 31c to draw in air and dissipate heat through the air inlet 334c.

[0623] Furthermore, since the suspension bracket 50c is located outside the floor brush device 100c, placing the second air intake section 332c inside the suspension bracket 50c of the floor brush device 100c extends the length of the air intake channel 33c, which helps to reduce the temperature of the air entering the air pump 31c. At the same time, placing the various parts of the air intake channel 33c inside the floor brush device 100c increases the aesthetics and practicality of the floor brush device 100c.

[0624] Please refer to Figures 30 and 34 to 36 together. In some embodiments, the first air intake section 331c includes a first air intake branch 335c and a second air intake branch 336c connected together, wherein the first air intake branch 335c is perpendicular to the axial direction of the roller brush 10c and is connected to the air intake port 334c; the second air intake branch 336c is parallel to the axial direction of the roller brush 10c and passes through the suspension bracket 50c.

[0625] In this way, the first air intake section 331c is concealed within the housing 22c and the suspension bracket 50c, improving the aesthetics of the floor brush device 100c.

[0626] For example, one end of the first air intake branch 335c is connected to the air intake 334c, and the other end of the first air intake branch 335c extends into the interior of the housing 22c perpendicular to the axial direction of the roller brush 10c (that is, perpendicular to the surface of the housing 22c) and connects to one end of the second air intake branch 336c. Meanwhile, the second air intake branch 336c is arranged parallel to the axial direction of the roller brush 10c, and the other end of the second air intake branch 336c passes through the suspension bracket 50c. The first air intake branch 335c and the second air intake branch 336c can be connected perpendicularly to each other, or they can be connected by a smooth curve at the connection point. This application does not limit the implementation of the embodiment to meet various needs.

[0627] Please refer to Figure 37. In some embodiments, there are multiple first intake branches 335c and intake ports 334c, and all of the multiple first intake branches 335c are connected to the second intake branch 336c.

[0628] Thus, the arrangement of multiple air inlets 334c can increase the air intake area and effectively suppress the heat generation of the drive component 20c.

[0629] For example, multiple air inlets 334c are disposed on the surface of the housing 22c, and the multiple air inlets 334c can be arranged sequentially along a direction perpendicular to the axis of the roller brush 10c. That is to say, the projection of the multiple air inlets 334c in the vertical direction after being connected in sequence is perpendicular to the projection of the axis of the roller brush 10c in the vertical direction. At the same time, the multiple air inlets 334c are respectively connected to multiple first air intake branches 335c, and the multiple first air intake branches 335c extend perpendicularly to the surface of the housing 22c into the interior of the housing 22c, and finally connect with the second air intake branch 336c.

[0630] It should be noted that the connection angle between the first air intake branch 335c and the second air intake branch 336c can be vertical, obtuse, acute, or a continuous arc, etc. The air intake ports 334c can be evenly arranged around the housing 22c in the rotation direction of the roller brush 10c, or concentrated at a certain position of the housing 22c in the rotation direction of the roller brush 10c (for example, multiple air intake ports 334c can be concentrated on the upper or lower side of the housing 22c, etc.). The embodiments of this application do not limit this, so as to meet various needs.

[0631] In addition, multiple air inlets 334c can be arranged sequentially along a direction parallel to the axis of the roller brush 10c. At the same time, multiple air inlets 334c are connected to multiple first air intake branches 335c respectively. Multiple first air intake branches 335c are perpendicular to the surface of the housing 22c and extend into the interior of the housing 22c, and finally connect with the second air intake branch 336c.

[0632] The embodiments of this application do not limit the specific arrangement of the first air intake branch 335c or the specific number of air intakes 334c. The projection of multiple air intakes 334c in the vertical direction and the projection of the axis of the roller brush 10c in the vertical direction can be perpendicular, parallel, or intersect at a certain angle. The number of air intakes 334c can be 2, 3, 4, etc., to meet various needs.

[0633] Please refer to Figures 31 and 32. In some embodiments, the second air intake section 332c is integrated within the suspension bracket 50c and integrally formed with the suspension bracket 50c.

[0634] This ensures that the material and structural strength between the second air intake section 332c and the suspension bracket 50c remain consistent at the connection point, thereby improving the airtightness of the second air intake section 332c.

[0635] Specifically, the second air intake section 332c and the suspension bracket 50c are a seamless or nearly seamless integral continuous structure to ensure the airtightness of the second air intake section 332c.

[0636] Please refer to Figures 30 and 31. In some embodiments, the air inlet 334c is located on the side of the central axis of the roller brush 10c away from the ground.

[0637] This prevents water from entering the air intake channel 33c from the air inlet 334c when cleaning the roller brush 10c.

[0638] Specifically, in the vertical direction, the air inlet 334c is located at the upper part of the roller brush 10c, that is, on the side of the roller brush 10c whose central axis is furthest from the ground. Because the lower part of the roller brush 10c needs to be immersed in water for cleaning, positioning the air inlet 334c at the upper part of the roller brush 10c prevents water from flowing into the air intake channel 33c during cleaning, thus avoiding any impact on the spray assembly 30c and increasing the operational stability and service life of the spray assembly 30c.

[0639] Of course, in some embodiments, when cleaning the roller brush 10c, the roller brush 10c does not need to be immersed in water, so that even if the air inlet 334c is located on the side of the central axis of the roller brush 10c close to the ground, it will not affect the function and reliability of the floor brush device 100c. In this case, the air inlet 334c can be located on either side of the central axis of the roller brush 10c.

[0640] In this application embodiment, the type of cleaning device 200c is not limited to meet various needs. The cleaning device 200c can be an environmental cleaning device 200c such as a floor scrubber or mop. The cleaning device 200c includes the floor brush device 100c of any of the above embodiments. Therefore, it can possess all the technical features and effects of the floor brush device 100c, resulting in better cleaning and self-cleaning effects, better operational stability and service life, and improved user experience.

[0641] Please refer to Figure 38. A cleaning system 300c includes a base station and the cleaning device 200c as described above, wherein the base station is used to supply power to the cleaning device 200c and / or to clean the cleaning device 200c.

[0642] In this application embodiment, the type of cleaning device 200c is not limited to meet various needs. The cleaning system 300c includes a base station and the aforementioned cleaning device 200c. The base station is used to supply power to the cleaning device 200c and / or to clean the cleaning device 200c. The cleaning system 300c can possess all the technical features and effects of the aforementioned cleaning device 200c, resulting in better cleaning and self-cleaning effects, better operational stability and service life, and improved user experience.

[0643] Currently, to prevent dust from accumulating on the HEPA filter during vacuuming, floor scrubbers and other cleaning equipment use atomizing nozzles in the recovery channel to spray water towards the dust. However, these nozzles have precise nozzle openings and small orifices, making them prone to clogging. For example, in floor scrubbers, to better and more promptly supply water to the atomizing module, reduce the potential risks of residual liquid in the pipes and blockages, and improve protection for components like the motor during dry vacuuming, the clean water tank is designed to be located on top of the brush head. This also lowers the center of gravity of the cleaning device, making handheld cleaning easier for users. However, because the clean water tank of a floor scrubber needs to be frequently removed for refilling, the open supply channel allows airborne dust particles to easily enter the supply channel on the brush assembly, introducing impurities larger than the nozzle orifice into the water. These impurities, carried by the water flow into the atomizing module, can cause nozzle blockage, uneven atomization, or even module damage, severely affecting the stability and reliability of the atomization dust suppression technology.

[0644] In view of this, embodiments of this application provide a cleaning device aimed at overcoming at least one of the aforementioned technical problems.

[0645] In the following embodiments, a height direction is introduced, which is parallel to the overall height direction of the cleaning device when it is used on the surface to be cleaned in this embodiment. With a roughly flat floor as a reference for the surface to be cleaned, the height direction is roughly perpendicular to the surface to be cleaned.

[0646] As shown in Figures 39 and 40, the cleaning device according to an embodiment of this application includes a spray assembly, a floor brush assembly 10d, and a clean water tank assembly 40d.

[0647] Specifically, the floor brush assembly 10d includes a floor brush body 12d, which defines a recovery channel 11d. A spray assembly is disposed on the floor brush assembly 10d, and the spray assembly includes a liquid supply channel 21d and a first nozzle. The nozzle of the first nozzle is located within the recovery channel 11d. The liquid supply channel 21d has an inlet and a first outlet connected to the first nozzle, and the inlet and outlet are connected. The clean water tank assembly 40d includes a clean water tank body 41d, which is detachably connected to the floor brush body 12d. The clean water tank body 41d includes an outlet, which is connected to and communicates with the inlet. A filter assembly 30d is provided at the inlet of the liquid supply channel 21d. Figure 44 shows the recovery channel 11d.

[0648] In detail, the recovery channel 11d of the brush body 12d is used for dust recovery. The nozzle of the first nozzle is located inside the recovery channel 11d, allowing the first nozzle to spray liquid into the recovery channel 11d. The sprayed liquid can effectively moisten the dust particles flowing during the dust collection process, reduce dust generation, and reduce the disorderly diffusion of dust in the recovery channel 11d and the clogging of the HEPA filter 32d. The water tank body 41d in the water tank assembly 40d is used to store the liquid required for cleaning operations, such as clean water and diluted cleaning agents. The water tank body 41d is detachably connected to the brush body 12d, making it easy for users to remove it independently to add water or replace it, meeting the portability requirements of the cleaning device. When the water tank body 41d is installed on the brush body 12d, its outlet is connected to and conducts with the liquid inlet, so that the liquid in the water tank body 41d can directly enter the liquid supply channel 21d after flowing out, and then flow to the first nozzle through the liquid supply channel 21d. A filter assembly 30d is installed at the inlet of the liquid supply channel 21d. When the clean water tank body 41d is removed for water addition or cleaning, the filter assembly 30d can prevent impurities from entering the liquid supply channel 21d. Furthermore, for ease of cleaning, the filter assembly 30d is positioned at the inlet of the liquid supply channel 21d, rather than inside the channel itself. This avoids the accumulation of dust particles between the upstream section of the filter assembly 30d and the inlet, compared to placing it within the channel itself, downstream of the inlet. The cleaning device can move along a predetermined path to clean the surface to be cleaned, such as a floor or carpet.

[0649] The overall function of the embodiments of this application has been described above. The following is a detailed description of each component of the cleaning device.

[0650] The floor brush assembly 10d includes a floor brush body 12d and a retraction channel 11d. The retraction channel 11d can be located either inside or outside the floor brush body 12d. The retraction channel 11d is used to connect to a vacuuming system, which can be installed on the floor brush body 12d. Some floor scrubbers have a hand handle connected to the floor brush body 12d, and the vacuuming system can also be installed on the hand handle. A brush head 18d can also be installed at the bottom of the floor brush body 12d. The brush head 18d can be bristles or a roller brush. The bristles can be made of wear-resistant nylon or anti-static fiber to suit different surfaces to be cleaned, such as floors and carpets.

[0651] In some embodiments, the inlet of the recycling channel 11d can be designed as a flared, funnel-shaped structure with guide slopes at the edges to guide ground dust smoothly into the channel with airflow or liquid flow. In some embodiments, the inner wall of the recycling channel 11d can also be fitted with an anti-stick coating, such as a Teflon coating, to reduce dust adhesion.

[0652] The spray assembly is mounted on the floor brush assembly 10d, for example, by snap-fit ​​connection or threaded connection. One end of the liquid supply channel 21d is connected to a clean water tank or cleaning fluid container. The other end of the liquid supply channel 21d is connected to the first nozzle through the first liquid outlet. The liquid inlet is equipped with a filter assembly 30d to prevent impurities from accumulating in the stagnant section between the liquid inlet and the filter assembly 30d.

[0653] The liquid can be clean water or a special cleaning agent, which is delivered to the first nozzle from the liquid supply channel 21d by a pressure pump or gravity flow.

[0654] The clean water tank body 41d can be located at the upper end, lower end, or side end of the floor brush body 12d; this application makes no limitation thereto. In some embodiments, the clean water tank body 41d can also be provided with a liquid level observation window. When the clean water tank body 41d is located at the upper end of the floor brush body 12d, a guide slope can be provided at the bottom of the clean water tank body 41d to ensure that the liquid converges towards the outlet until it flows out completely. The inclination angle of the guide slope can be 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, and 15°, etc.

[0655] In some embodiments, the water tank body and the floor brush body 12d are connected by snap-fit, facilitating assembly and disassembly. In some embodiments, the water tank body can also be connected to the floor brush body 12d via magnetic attraction.

[0656] In some embodiments, the outlet of the clean water tank body 41d can be configured as an inverted cone shape, with the larger end close to the clean water tank body 41d and the smaller end close to the filter assembly 30d.

[0657] The filter assembly 30d can adopt a multi-layer composite structure, such as a combination of a primary metal filter 32d and a secondary polymer fiber filter membrane. The primary metal filter 32d can be used to intercept large particles such as hair and sand, while the secondary polymer fiber filter membrane can be used to filter fine dust.

[0658] In some embodiments, the filter assembly 30d includes a filter frame 31d and a filter screen 32d disposed on the filter frame 31d. The filter frame 31d is detachably connected to the liquid inlet, facilitating user disassembly and cleaning. For example, an annular snap-fit ​​groove can be provided at the liquid inlet, and elastic hooks can be provided on the edge of the filter frame 31d accordingly, allowing the user to disassemble the filter assembly 30d for cleaning by rotating or pressing. In some embodiments, the filter frame 31d can also be designed as a transparent material, such as polycarbonate plastic, to facilitate user observation of impurity accumulation on the surface of the filter screen 32d and timely cleaning.

[0659] According to the cleaning device of this application embodiment, by setting a filter component 30d at the liquid inlet of the liquid supply channel 21d, when the clean water tank body 41d is removed for water addition or cleaning, the filter component 30d blocks impurities from entering the liquid supply channel 21d, preventing the nozzle of the first nozzle from being blocked by impurities, ensuring the reliable operation of the first nozzle, and enabling it to continuously and stably spray liquid into the recovery channel 11d, thereby improving the overall cleaning efficiency and operational reliability of the cleaning device.

[0660] In actual use, if the filter assembly 30d is to be detachably connected to the liquid inlet for easy cleaning, the filter assembly 30d and the liquid inlet are not tightly connected. This may result in impurities or liquid flowing directly into the liquid supply channel 21d without being filtered, causing dust particles and other impurities to clog the nozzles and affecting the normal operation of the spray assembly. Therefore, a cleaning device is urgently needed that can ensure the installation gap between the filter assembly 30d and the liquid inlet while being easy to disassemble and clean, so as to prevent dust, impurities or liquid from entering directly.

[0661] As shown in Figures 40-43, in some embodiments, the cleaning device further includes a mounting base 16d, a liquid supply channel 21d connected to the mounting base 16d, the mounting base 16d defining an inlet and outlet, a first engaging portion 163d provided on the mounting base 16d, a filter assembly 30d including a filter frame 31d and a filter screen 32d engaged in the filter frame 31d, one end of the filter frame 31d being provided with a closed annular edge 311d along its circumferential direction, the first engaging portion 163d being an annular magnet, and a magnetic attracting element being provided on the inner side of the edge 311d, the first engaging portion 163d and the edge 311d being magnetically attracted to each other.

[0662] In some other embodiments, the liquid supply channel 21d is connected to the mounting base 16d, the mounting base 16d defines the liquid inlet, the mounting base 16d is provided with a first engaging part 163d, the filter assembly 30d includes a filter frame 31d and a filter screen 32d engaged in the filter frame 31d, one end of the filter frame 31d is provided with an edge 311d forming a closed ring along its own circumferential direction, and the edge 311d engages with the first engaging part 163d.

[0663] According to the cleaning device of this application embodiment, the mounting base 16d is engaged with the edge 311d of the filter frame 31d of the filter assembly 30d via the first engaging portion 163d. Since the closed annular edge 311d extends circumferentially along the filter frame 31d, it achieves circumferential fixation when engaged with the first engaging portion 163d, ensuring a tight fit between the filter assembly 30d and the liquid inlet. The edge 311d forms a continuous circumferential seal, preventing unfiltered liquid from leaking from the connection between the liquid inlet and the filter assembly 30d, ensuring that all liquid entering the liquid supply channel 21d is filtered by the filter screen 32d. The engagement of the edge 311d with the first engaging portion 163d allows for quick installation or removal of the filter assembly 30d, enabling the user to clean or replace the filter screen 32d without the need for tools.

[0664] In some embodiments, a mounting base 16d is provided on the brush body 12d, the mounting base 16d is located at the first end of the liquid supply channel 21d, the mounting base 16d defines a circular liquid inlet, and a first engaging portion 163d is provided on the outer side of the mounting base 16d. In some embodiments, the first engaging portion 163d is formed in a ring shape. In some embodiments, the first engaging portion 163d includes multiple sets of spaced elastic buckles, and the inner side of the edge 311d is provided with a groove that matches the first engaging portion 163d. In some embodiments, the first engaging portion 163d includes multiple sets of spaced grooves, and the inner side of the edge 311d is provided with a barbed buckle that matches the first engaging portion 163d. It can be locked with the mounting base 16d by pressing.

[0665] The filter frame 31d can be made of translucent polypropylene. The filter screen 32d is disposed within the filter frame 31d and may include multiple layers of filter screen 32d. For example, the layer furthest from the filter frame 31d may be a stainless steel woven mesh with a pore size of 0.5 mm, and the layer closest to the filter frame 31d may be a polyester fiber filter membrane with a pore size of 50 μm.

[0666] Of course, the shape of the liquid inlet is not limited to a circle; it can also be a square, rectangle, oval, triangle, or polygon.

[0667] As shown in Figures 40, 41, 44, and 45, in some embodiments, the filter frame 31d and the filter screen 32d define a filter chamber that opens toward the clean water tank body 41d, with the outlet of the clean water tank body 41d located within the filter chamber. This allows the liquid flowing out of the outlet to flow directly into the filter chamber, preventing dust particles and suspended impurities from remaining in the filter chamber.

[0668] As shown in Figures 40, 41 and 45, in some embodiments, the clean water tank assembly 40d further includes an end cap 42d, which is connected to the clean water tank. The end cap 42d includes a fixedly connected end cap 42d body and a limiting bracket 43d. The limiting bracket 43d protrudes from the end cap 42d body and is engaged in the filter frame 31d, and the limiting bracket 43d defines the outflow outlet.

[0669] The limiting bracket 43d protrudes from the end cap 42d and is inserted into the filter frame 31d, that is, it is inserted into the filter cavity formed by the filter frame 31d and the filter screen 32d. The snap-fit ​​structure between the limiting bracket 43d and the filter frame 31d ensures that the outlet is directly connected to the filter cavity. When the limiting bracket 43d is inserted into the filter frame 31d, the outlet is completely inside the filter cavity. After the liquid flows out from the outlet, it must pass through the filter screen 32d before entering the inlet of the liquid supply channel 21d. The limiting bracket 43d not only plays a positioning role, but also forms a limiting support for the filter component 30d, preventing the outlet from shifting during the installation of the clean water tank and causing the liquid to flow around. It also prevents dust particles and other impurities mixed in during the water addition process from bypassing the filter component 30d and directly entering the water circuit, effectively protecting the fine nozzle of the first spray head from being blocked.

[0670] In some embodiments, the limiting bracket 43d is columnar or columnar in shape. In some embodiments, the limiting bracket 43d and the end cap 42d are integrally injection molded. The height direction of the limiting bracket 43d is aligned with the axis of the water tank outlet, ensuring that the outlet is vertically aligned with the filter chamber.

[0671] The outer surface of the limiting bracket 43d can be provided with a guide structure, such as a chamfer or rounded transition, to facilitate insertion into the filter frame 31d.

[0672] As shown in Figure 45, in some embodiments, the outer wall of the limiting bracket 43d is provided with an annular protrusion 432d, which forms an annular engagement with the inner wall of the filter frame 31d to prevent loosening. The surface of the annular protrusion 432d can also be provided with anti-slip texture, which can further enhance the friction between it and the inner wall of the filter frame 31d.

[0673] In some embodiments, the end of the limiting bracket 43d is provided with multiple elastic snap claws, the ends of which are provided with barbs. The inner wall of the filter frame 31d is provided with multiple U-shaped slots at corresponding positions. After the snap claws are inserted, the barbs engage with the U-shaped slots.

[0674] In some embodiments, the end of the limiting bracket 43d is a flared opening, and the inner wall of the flared opening can also be provided with a flow guiding slope so that the liquid can be distributed and contacted with the filter screen 32d after flowing out, thereby forming a buffer and reducing the flow rate of the liquid on the surface of the filter screen 32d.

[0675] As shown in Figures 41 and 45, in some embodiments, the outer periphery of the limiting bracket 43d is provided with a locking groove 431d that forms a closed annular shape along its own circumferential direction. The locking groove 431d is fitted inside the first sealing member 44d, and the first sealing member 44d abuts against the inner wall of the locking groove 431d and the inner wall of the filter frame 31d.

[0676] The snap-fit ​​groove 431d is used to fix the first seal 44d. The closed annular snap-fit ​​groove 431d ensures that the first seal 44d is subjected to uniform force, avoiding seal failure caused by excessive local pressure. The elastic deformation of the first seal 44d forms a 360° annular seal, ensuring that the liquid flowing out of the clean water tank body 41d has no leakage channels at the connection between the limiting bracket 43d and the filter frame 31d. All liquid must be filtered by the filter screen 32d before entering the liquid supply channel 21d. In this way, the filtration effect of the filter assembly 30d is guaranteed, and the liquid overflow during filling or spraying is prevented. This effectively protects the fine nozzle of the first spray head from being blocked by impurities, ensuring that the spray assembly continuously and stably sprays clean liquid into the recovery channel 11d to moisten the dust.

[0677] The snap-fit ​​grooves 431d are evenly distributed along the outer periphery of the limiting bracket 43d, and have a rectangular or trapezoidal cross-section. In some embodiments, the upper and lower edges of the snap-fit ​​grooves 431d can be chamfered to facilitate the smooth insertion of the first seal 44d during installation.

[0678] Multiple annular corrugations can be set on the outer periphery of the first seal 44d, and after the limiting bracket 43d is inserted into the filter frame 31d, it can be interference-fitted with the first filter bracket.

[0679] In some embodiments, the outer wall of the limiting bracket 43d is provided with an annular protrusion 432d, and the annular protrusion 432d and the outer wall of the limiting bracket 43d together define the snap-fit ​​groove 431d.

[0680] As shown in Figure 40, in some embodiments, a drain valve 45d is provided inside the end cap 42d body. The drain valve 45d includes a valve stem 451d and a spring 452d. One end of the spring 452d is connected to the valve stem 451d. A support column 33d is provided inside the filter frame 31d. The support column 33d abuts against the valve stem 451d to compress the spring 452d for conduction.

[0681] In detail, when the clean water tank body 41d and the floor brush assembly 10d are installed, the support column 33d pushes the valve rod 451d upward, compressing the spring 452d to open the drain valve 45d. The liquid in the clean water tank body 41d flows into the filter chamber through the outlet and is filtered by the filter screen 32d before entering the liquid supply channel 21d. When the clean water tank body 41d is disassembled, the spring 452d returns to its original position and pushes the valve rod 451d to close the drain valve 45d, preventing the liquid in the clean water tank body 41d from flowing out. This structure enables the automatic opening and closing of the drain valve 45d. During installation, the valve stem 451d is activated by the support column 33d, ensuring the liquid flow path is open. During disassembly, the spring 452d forces the valve stem 451d to close, preventing liquid from overflowing or leaking from the clean water tank body 41d during disassembly. This improves the convenience of adding water or performing maintenance operations and prevents unfiltered liquid from accumulating in the valve stem 451d area, ensuring that the spray assembly receives clean liquid every time it is used. This effectively protects the nozzle of the first spray head and further enhances the reliability of the cleaning device and the user experience.

[0682] The support column 33d can be cylindrical, square, or conical. The top surface of the support column 33d can be provided with a guide slope to facilitate the axial movement of the valve stem 451d when it contacts the bottom end of the valve stem 451d.

[0683] In some embodiments, the support column 33d is disposed on the brush body, and the filter frame 31d is provided with an inlet, through which the support column 33d passes.

[0684] As shown in Figures 40-43, in some embodiments, the support column 33d is disposed on the filter frame 31d, and the filter frame 31d and the support column 33d are integrally formed. The support column 33d is vertically fixed to the inner wall of the filter frame 31d. The support column 33d can be integrally injection molded with the filter frame 31d, or it can be an embedded metal support, such as brass or aluminum alloy, to ensure that the support column 33d has sufficient rigidity to push the valve stem 451d and compress the spring 452d.

[0685] As shown in Figure 43, in some embodiments, the bottom of the mounting base 16d is also provided with a limiting post 164d protruding upwards. The support post 33d is integrally formed with the filter frame 31d. The support post 33d is provided with a cavity 331d inside. The cavity 331d opens towards the bottom of the mounting base 16d, and the limiting post 164d is locked in the cavity 331d.

[0686] The limiting post 164d can position the filter frame 31d, further limiting the installation position of the filter frame 31d, ensuring that the axis of the filter chamber is aligned with the outlet of the clean water tank body 41d and the inlet of the liquid supply channel 21d, and preventing the filter assembly 30d from shifting. The axes of the limiting post 164d and the cavity 331d can be coaxially set with the axis of the support post 33d.

[0687] As shown in Figures 40 and 41, in some embodiments, the floor brush body 12d includes a first housing 14d and a second housing 15d that are interlocked with each other. The first housing 14d and the second housing 15d together define a first mounting cavity. A recycling channel 11d is provided in the first mounting cavity. The side of the first housing 14d away from the second housing 15d defines a second mounting cavity. A clean water tank body 41d is snapped into the second mounting cavity. A mounting base 16d is snapped into the second housing 15d. The first housing 14d and the mounting base 16d are snapped together and together define a limiting groove 162d. The edge 311d is snapped into the limiting groove 162d.

[0688] In detail, the recycling channel 11d is set inside the first mounting cavity, which can ensure the independence and smoothness of the dust suction airflow path and prevent the internal recycling channel 11d from being deformed by external force. The second mounting cavity is located outside the first housing 14d, which facilitates the disassembly and installation of the clean water tank assembly 40d, and at the same time provides a dedicated installation space for the installation of the clean water tank assembly 40d, providing a stable support for the clean water tank.

[0689] The first housing 14d and the second housing 15d are connected by a snap-fit ​​connection, enabling rapid assembly. The first housing 14d and the second housing 15d can be connected by a snap-fit ​​or a combination of snap-fit ​​and fasteners. The first housing 14d snaps into the mounting base 16d and together define a limiting groove 162d, which can snap and limit the edge 311d of the filter frame 31d, ensuring that the axis of the filter chamber is aligned with the outlet of the clean water tank body 41d and the inlet of the liquid supply channel 21d, preventing the filter assembly 30d from shifting due to deformation of the first housing 14d or the mounting base 16d.

[0690] The limiting groove 162d is formed as an annular groove, and the outer surface of the first housing 14d is formed as part of the annular groove. The wall thickness of the area of ​​the first housing 14d corresponding to the annular groove is not reduced compared to other areas, and the bottom of the first housing 14d presses against the edge 311d.

[0691] As shown in Figures 40 and 41, in some embodiments, a second stop portion 141d is provided on the side of the first housing 14d facing the mounting base 16d. The second stop portion 141d is located on one side of the free end of the edge 311d. A mounting base 161d is provided on the mounting base 16d. The second stop portion 141d extends into the mounting base 161d. In this way, the second stop portion 141d, the bottom wall of the first housing 14d, and the top wall of the mounting base 16d together define a limiting groove 162d.

[0692] In some embodiments, the second stop portion 141d is also directly attached to the outer surface of the edge 311d of the filter frame 31d, and the pre-tightening force when the first housing 14d and the mounting base 16d are fastened together forms radial pressure to ensure that the filter frame 31d does not shift.

[0693] As shown in Figures 40 and 41, in some embodiments, the filter frame 31d further includes a first stop portion 312d extending toward the direction away from the filter screen 32d and beyond the edge 311d. The first housing 14d is provided with a clearance opening, and the limiting bracket 43d passes through the clearance opening. The first stop portion 312d is located in the clearance opening and abuts against the inner wall of the clearance opening.

[0694] The first stop 312d contacts the inner wall of the clearance opening, which restricts the position of the filter frame 31d in the axial direction, ensuring that the support column 33d and the valve stem 451d can be aligned, so that the support column 33d can precisely abut against the valve stem 451d. At the same time, the first stop 312d can also guide and limit the movement of the limiting bracket 43d into the first filter bracket, so that the axis of the limiting bracket 43d is consistent with the axis of the first filter bracket when it passes through the clearance opening. In this way, it can not only avoid the installation deviation of the filter frame 31d, but also improve the stability and alignment accuracy when the clean water tank body 41d is connected to the floor brush body 12d.

[0695] The clearance can be circular, square, or oval.

[0696] In some embodiments, the first stop portion 312d is perpendicular to the edge 311d. The first stop portion 312d includes multiple sub-parts, which are evenly distributed circumferentially along the filter frame 31d. Alternatively, the first stop portion 312d can be a single unit, arranged in a closed ring. The first stop portion 312d can also be provided with a multi-step design, with an assembly groove provided on the inner wall of the clearance opening. A third sealing element can be fitted into the assembly groove. The first step is used for primary positioning, and the secondary steps are engaged in the assembly groove and abut against the third sealing element.

[0697] The first stop portion 312d can be snapped into or integrally formed with the filter assembly 30d. When integrally formed, a metal reinforcing sheet can also be embedded. The end face of the first stop portion 312d can be provided with anti-slip texture. An elastic buffer layer can also be provided on the side wall of the first stop portion 312d opposite to the inner wall of the clearance opening to avoid rigid collision with the first housing 14d during assembly.

[0698] As shown in Figure 41, in some embodiments, a second stop 141d is provided on the side of the first housing 14d facing the mounting base 16d. The second stop 141d is located on one side of the free end of the edge 311d. A mounting base 161d is provided on the mounting base 16d. A second seal 17d is snapped into the mounting base 161d. The second stop 141d abuts against the second seal 17d.

[0699] In detail, the second seal 17d is snapped into the mounting base 161d of the mounting base 16d for easy disassembly and replacement. It also abuts against the second stop 141d of the first housing 14d, which converts the mechanical force when the first housing 14d and the mounting base 16d are fastened into a compressive force on the second seal 17d. This causes the sealing effect to automatically improve as the fastening force increases. At the same time, it forms a stable structural fit with the second stop 141d and the edge 311d, ensuring that the connection between the first housing 14d and the mounting base 16d maintains a reliable sealing state for a long time, thereby improving the overall reliability and service life of the cleaning device.

[0700] As shown in Figures 39, 44 and 45, in the cleaning device according to the embodiment of this application, the clean water tank body 41d is disposed on the top of the floor brush body 12d. The clean water tank body 41d is flat, and the liquid inlet is disposed directly below the clean water tank body 41d with the opening facing upward.

[0701] The water tank body 41d is located on top of the floor brush body 12d. The water tank body 41d is flat, which can reduce the overall height of the machine to facilitate cleaning low areas such as the bottom of furniture. The liquid inlet faces downward and the opening faces upward, so that the outlet of the water tank body 41d can be accurately inserted into the filter component 30d of the floor brush body 12d when it is installed. The liquid flows naturally to the filter chamber due to gravity and the path is short and straight, avoiding flow resistance.

[0702] The cleaning device according to the embodiments of this application further includes a second nozzle, and the liquid supply channel 21d also has a second liquid outlet connected to the second nozzle. The floor brush assembly 10d includes a floor brush body 12d, on which a brush head 18d and a second nozzle are disposed. The nozzle of the second nozzle is disposed opposite to the brush head 18d. A fluid diverter is disposed in the liquid supply channel 21d downstream of the filter assembly 30d. The fluid diverter can selectively connect the liquid inlet to one of the first liquid outlet and the second liquid outlet.

[0703] The liquid supply channel 21d selectively connects to either the first or second liquid outlet via a reversing component, with the second nozzle facing the brush head 18d, thus increasing the functionality of the cleaning device. When the fluid reversing component connects the inlet and the second outlet, the filtered clean liquid is directly sprayed through the second nozzle onto the area of ​​action of the brush head 18d, such as the floor or the brush head itself. This specifically wets stubborn stains or washes away dust tangled in the brush head 18d's hair, enhancing cleaning power in conjunction with the mechanical friction of the brush head 18d. When switching to the first outlet, the liquid is sprayed into the recovery channel 11d, suppressing dust during vacuuming. The fluid reversing component is located downstream of the filter assembly 30d, ensuring that both liquid outlets are filtered by the filter screen 32d, preventing impurities from clogging the nozzles of either spray head. Users can control the reversing component to switch spray modes according to different cleaning scenarios, such as cleaning tile grout or deep cleaning carpets.

[0704] This application proposes a cleaning system, including the cleaning device described above, and also including a base station or charging dock adapted to the cleaning device.

[0705] When using a base station compatible with the cleaning equipment, the base station can provide functions such as liquid supply, liquid drainage, self-cleaning, drying and charging for the cleaning equipment. When using a charging dock, the charging dock can provide functions such as charging, self-cleaning and drying for the cleaning equipment.

[0706] The base station provides liquid supply and drainage functions that can automatically replenish the liquid in the clean water tank (41d) and discharge the waste liquid in the sewage tank, eliminating the need for users to frequently add water and empty the wastewater, significantly reducing the frequency of operation; the self-cleaning function automatically rinses easily soiled parts such as the brush head (18d) after the cleaning equipment is returned to its place, avoiding the tedious manual disassembly and cleaning; the drying function accelerates the drying of the brush head (18d) through hot air or ventilation design, reducing bacterial growth and odor generation, and improving the hygiene of the cleaning equipment.

[0707] The charging dock provides charging functionality to ensure the cleaning device is always fully charged, guaranteeing reliable battery life. Both the base station and the charging dock improve cleaning efficiency, extend the lifespan of the cleaning equipment, and reduce the risk of malfunction, making the entire cleaning system intelligent, convenient, and reliable.
