Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly to a control method for cleaning equipment and a cleaning equipment. Background Technology

[0002] Cleaning equipment such as floor scrubbers can clean surfaces (such as floors) by spraying steam onto them. These cleaning devices are usually equipped with multiple steam nozzles that point vertically at the surface to be cleaned, in order to increase the steam coverage and shorten the distance between the steam nozzles and the surface to be cleaned.

[0003] In practical applications, while using a single steam generator to drive multiple steam nozzles provides a large steam coverage area, it is not very effective at cleaning heavily soiled areas. If only a single steam nozzle from the multiple nozzles is selected, the nozzles, located at the bottom of the unit and perpendicular to the ground, are difficult to aim at for heavily soiled areas, negatively impacting the user experience.

[0004] Therefore, how to improve the cleaning efficiency of steam in cleaning equipment for locally heavy dirt, and enable users to accurately determine the steam coverage area to improve the user experience, is an urgent problem to be solved. Summary of the Invention

[0047] Figure 1 This is a schematic diagram of a cleaning device, such as a floor scrubber. The cleaning device includes at least a body assembly 1 and a floor brush assembly 2. The body assembly 1 and the floor brush assembly 2 are rotatably connected. The top of the body assembly 1 is provided with a handle 11, and the floor brush assembly 2 is movable on the surface to be cleaned (such as the ground).

[0048] In one possible implementation, the user can move the floor brush assembly 2 on the surface to be cleaned and control the direction of movement of the floor brush assembly 2 by pushing or pulling the handle 11.

[0049] The cleaning equipment can travel in a first direction or a second direction. The first and second directions are used to distinguish between two different directions of travel for the cleaning equipment. For example, the first direction of travel can be the forward direction of the cleaning equipment; the second direction of travel can be the backward direction of the cleaning equipment.

[0050] In one possible implementation, the brush assembly 2 may include: a brush housing 21, a controller (not shown), a walking system 22, and a cleaning component 23.

[0051] In one possible implementation, the brush assembly 2 and / or the body assembly 1 may also include a sensing system (not shown).

[0052] The cleaning component 23 may specifically include one or more of the following: a roller brush, etc.

[0053] In one possible implementation, the cleaning equipment also includes a clean water tank, a wastewater tank, and a suction device. Any one of the clean water tank, wastewater tank, and suction device can be located in the floor brush assembly 2 or in the body assembly 1.

[0054] The controller described above may include a microcontroller unit (MCU). Of course, the controller may also include other devices capable of control functions.

[0055] In one possible implementation, the cleaning component 23 is located within the main brush chamber at the bottom of the brush housing 21. The main brush chamber is connected to the suction channel of the cleaning device. A suction device is used to remove dirt, wastewater, etc., from the cleaning component.

[0056] refer to Figure 1 The walking system 22 is mounted on the floor brush housing 21 and is used to support the movement of the floor brush assembly 2. The walking system 22 may or may not be powered.

[0057] A sensing system may be provided on the body assembly 1 and / or the floor brush assembly 2. The sensor system may include at least one of the following: a vision sensor, a laser sensor, a gyroscope, an accelerometer, a speed sensor, a mechanical sensor, an infrared sensor, an ultrasonic sensor, and a visual sensor, to acquire at least one of the following: motion status information, position information, obstacle information, and dirt information of the cleaning equipment.

[0058] It is understood that the above-described cleaning equipment is for illustrative purposes only and does not constitute a limitation of the embodiments described in this specification.

[0059] In some embodiments, the cleaning device has multiple steam nozzles positioned below the brush housing 21 (e.g., at the front of the roller brush along the first direction), pointing vertically towards the surface to be cleaned. These nozzles spray steam onto the surface to improve cleaning effectiveness, and the multiple nozzles increase steam coverage. However, this method is ineffective for dealing with locally heavy dirt. If only a single steam nozzle is selected to spray steam, its position and directionality make it difficult to target heavily soiled areas, impacting user experience. Furthermore, during self-cleaning, if steam cleaning of components such as the roller brush is required, the existing steam nozzles are not directed towards the roller brush, often necessitating the addition of a steam generator, increasing design complexity and cost.

[0060] Example 1 This embodiment provides a control method for a cleaning device. The cleaning device includes: a steam generating component for generating steam, a first steam ejection component, and a second steam ejection component, wherein the number of first steam nozzles in the first steam ejection component is less than the number of second steam nozzles in the second steam ejection component. like Figure 2The method includes: Step 201: During the cleaning process of the cleaning equipment cleaning the surface to be cleaned, the steam generating component is controlled to direct the generated steam to the first steam nozzle of the first steam ejection component or the second steam nozzle of the second steam ejection component.

[0061] Here, the control method can be executed by the controller of the cleaning equipment.

[0062] A steam generating assembly can be a device for heating water and converting it into steam. For example, a steam generating assembly may include a clean water tank, a first water pump, a pressure relief valve, a boiler, a scale box, valves, and pipes.

[0063] The first steam ejection assembly and the second steam ejection assembly can each be a structure that guides the steam generated by the steam generating assembly to the area to be cleaned. The first steam ejection assembly may include a first steam nozzle, and may also include pipes, switching valves, etc., connected to the first steam nozzle. The first steam ejection assembly may include a second steam nozzle, and may also include pipes, valves, etc., connected to the second steam nozzle. The steam nozzle can be designed to achieve a relatively concentrated or directional steam injection.

[0064] The steam generating assembly can direct the generated steam to the first steam nozzle of the first steam ejection assembly or the second steam nozzle of the second steam ejection assembly via valves and / or pipes. The steam generating assembly can switch the steam flow path via valves (such as solenoid control valves), allowing the steam to be guided to different steam ejection assemblies (first steam ejection assembly and second steam ejection assembly) for injection according to cleaning requirements.

[0065] The second steam ejection assembly may include a plurality of second steam nozzles, and the first steam ejection assembly may include one or more second steam nozzles.

[0066] In one possible implementation, the total opening area of ​​the first steam nozzle of the first steam ejection assembly is smaller than the total opening area of ​​the second steam nozzle of the second steam ejection assembly. Therefore, the steam ejected through the first steam nozzle of the first steam ejection assembly has a higher steam pressure, which is more conducive to cleaning dirt.

[0067] The first steam ejection assembly, by employing a smaller number of first steam nozzles, enables the first steam nozzles to provide a steam flow with concentrated injection characteristics and higher pressure. The second steam ejection assembly, with a larger number of second steam nozzles, achieves a wider steam coverage area.

[0068] In one possible implementation, the first steam ejection assembly and the second steam ejection assembly may each have independent steam inlets, and the steam generating assembly introduces steam into the first steam ejection assembly or the second steam ejection assembly through the steam inlet of the first steam ejection assembly or the steam inlet of the second steam ejection assembly, respectively.

[0069] Specifically, a switching valve (such as a two-position three-way solenoid valve) can be installed at the steam outlet of the steam generating assembly, and has two or more outlets, which are respectively connected to the steam pipes of the first steam ejection assembly and the second steam ejection assembly. By controlling the state of this switching valve, the steam flow path can be switched to the first steam ejection assembly or the second steam ejection assembly, and then steam is ejected from the first steam nozzle or the second steam nozzle.

[0070] For example, Figure 3 A partial view of the cleaning equipment, such as Figure 3 As shown, the cleaning equipment has multiple second steam nozzles 241 and one first steam nozzle 251 on the floor brush housing of the floor brush assembly 2. The controller can control the steam generated by the steam generating assembly to be ejected from the first steam nozzle 251 or the second steam nozzle 241 by controlling the switching valve of the steam generating assembly, thereby adapting to different cleaning scenarios.

[0071] This allows for flexible steam routing, directing either a smaller number of first steam nozzles or a larger number of second steam nozzles. When dealing with locally heavy dirt, the first steam nozzles can provide a concentrated, high-pressure steam stream, improving cleaning efficiency. For large-area cleaning, the second steam nozzles can achieve broader steam coverage. This provides a flexible steam cleaning method while improving cleaning effectiveness for stubborn, locally heavy dirt, thus enhancing the user experience.

[0072] In some embodiments, controlling the steam generating assembly to direct the generated steam to a first steam nozzle of the first steam ejection assembly or a second steam nozzle of the second steam ejection assembly includes at least one of the following: Upon receiving a powerful steam injection command, the steam generating component is controlled to direct the generated steam to the first steam nozzle of the first steam ejection component; Upon receiving a constant force steam injection command, the steam generating component is controlled to direct the generated steam to the second steam nozzle of the second steam ejection component.

[0073] Here, user commands for powerful steam injection and / or constant steam injection can be sent to the cleaning equipment via buttons, human-machine interface, and external control terminal.

[0074] For example, cleaning equipment can be equipped with physical buttons or knobs, allowing users to select the steam emission mode by operating these physical controls. A physical button in its first state corresponds to a high-power steam emission command, while another physical button in its first state corresponds to a constant-power steam emission command. The cleaning equipment can also be equipped with a touchscreen display, allowing users to issue commands by tapping the corresponding options on the screen. Users can also use a voice controller to issue voice commands to the cleaning equipment, instructing it to direct steam to specific steam nozzles.

[0075] Control based on high-pressure steam injection commands and / or constant-pressure steam injection commands allows users to select the steam direction according to actual needs, enabling precise operation for heavily soiled areas and reducing the problem of misalignment of steam nozzles.

[0076] In some embodiments, during the cleaning process of the cleaning device on the surface to be cleaned, controlling the steam generating assembly to direct the generated steam to the first steam nozzle of the first steam ejection assembly includes: Identify the target dirty area on the surface to be cleaned; Based on the dirt information of the target dirty area, the steam generating component is controlled to direct the generated steam to the first steam nozzle of the first steam ejection component or the second steam nozzle of the second steam ejection component; wherein, the dirt information includes at least one of the dirt area of ​​the target dirty area and the dirt type of the target dirty area.

[0077] The sensing system of the cleaning equipment can also be used to sense the dirt status of a target dirty area. The target dirty area may include at least one of the following: the area that can be covered by the steam spraying period of the first steam nozzle; the area that is predicted to be covered by the steam spraying from the first steam nozzle based on the movement information of the cleaning equipment.

[0078] For example, cleaning equipment can integrate optical sensors to identify dirty areas by analyzing the intensity of reflected light, color changes, or texture features of the surface to be cleaned. Sensing systems can determine the area of ​​dirt and / or identify the type of dirt through image recognition.

[0079] For example, cleaning equipment can capture images of the area to be cleaned using a built-in camera and use image processing algorithms to analyze information such as dirt spots and stain distribution in the image, thereby quantifying the degree of dirtiness.

[0080] Specifically, real-time images or spectral data of the target dirty area can be obtained through sensing systems on the cleaning equipment. Image processing algorithms or spectral analysis techniques are used to identify the type, area, and depth of the stains, quantifying this information as a dirt index. When the dirt index exceeds a preset threshold, the predetermined dirt condition is considered met. When the dirt index is below the preset threshold, or when no heavy stains of a specific type are detected, the predetermined dirt condition is deemed not met.

[0081] When a heavily soiled area is detected, steam is concentrated and delivered to a first steam jet assembly with a smaller number of nozzles to achieve high-intensity, precise steam jetting, effectively cleaning stubborn stains. When the area to be cleaned is lightly soiled or is undergoing routine cleaning, steam is delivered to a second steam jet assembly with a larger number of nozzles to achieve wide-area, uniform steam coverage, improving overall cleaning efficiency.

[0082] In this way, the cleaning equipment can judge the actual dirt level of the area to be cleaned, thereby adapting to different dirt conditions and improving cleaning efficiency. The adaptive steam guidance control mechanism reduces the overuse of high-intensity steam in lightly dirty areas and reduces the problem of insufficient steam coverage in heavily dirty areas, optimizing the utilization efficiency of steam resources and improving the overall intelligence level of cleaning and user experience.

[0083] In some embodiments, controlling the steam generating assembly to direct the generated steam to a first steam nozzle of the first steam ejection assembly or a second steam nozzle of the second steam ejection assembly based on the dirt information of the target dirty area includes: When the dirty area of ​​the target dirty area is less than or equal to a preset cleaning area, the steam generating component is controlled to direct the generated steam to the first steam nozzle of the first steam ejection component, wherein the preset cleaning area is determined based on the associated cleaning area of ​​the first steam nozzle.

[0084] In one possible implementation, if the dirty area of ​​the target dirty area is larger than a preset cleaning area, the steam generating component is controlled to direct the generated steam to the second steam nozzle of the second steam ejection component.

[0085] In one possible implementation, the steam ejected from the first steam nozzle covers a smaller area.

[0086] The first steam nozzle is used to spray higher steam pressure. Therefore, compared to the larger number of second steam nozzles, the steam coverage area sprayed by all the first steam nozzles is smaller. Thus, when the identified target dirty area is small and the steam sprayed by the first steam nozzles can cover it, the first steam nozzles can be used to spray steam onto the target dirty area for more targeted cleaning.

[0087] When the target dirty area is identified as large and the steam from the first steam nozzle cannot cover it, a second steam nozzle can be used to spray steam onto the target dirty area to achieve more targeted cleaning.

[0088] In this way, the cleaning equipment can determine the actual area of ​​dirt in the area to be cleaned, thereby adapting to different levels of dirt and improving cleaning efficiency. The adaptive steam guidance control mechanism enables the steam to adapt to different areas of dirt, optimizing the utilization efficiency of steam resources and improving the overall intelligence level of cleaning and user experience.

[0089] In some embodiments, controlling the steam generating assembly to direct the generated steam to the first steam nozzle of the first steam ejection assembly based on the dirt information of the target dirty area includes: When the type of dirt in the target dirty area is a predetermined type, the steam generating component is controlled to direct the generated steam to the first steam nozzle of the first steam ejection component.

[0090] The steam pressure sprayed through the first steam nozzle is greater and more effective at cleaning dirt. Therefore, for stubborn dirt (including sticky stains), such as porridge and rice, the first steam nozzle can be used to spray steam onto the target dirty area for more targeted cleaning.

[0091] When the type of dirt detected in the target dirty area is not the predetermined type, it can be removed using steam at normal pressure. A second steam nozzle can be used to spray steam into the target dirty area.

[0092] In this way, the cleaning equipment can make judgments based on the actual type of dirt in the area to be cleaned, thereby adapting to different types of dirt and improving cleaning efficiency.

[0093] In some embodiments, the cleaning device includes a floor brush assembly; Along the first direction of travel, the first steam nozzle points towards the surface to be cleaned at the front of the floor brush assembly; or; The first steam nozzle is pointed vertically at the surface to be cleaned.

[0094] A roller brush in a cleaning device is a component used to physically scrub the surface to be cleaned. It can include bristles, a brush roller, etc. It removes stains by rotating and contacting the surface to be cleaned.

[0095] Figure 4 for Figure 1 The diagram shows a partial cross-sectional view of the floor brush assembly 2. Figure 4 As shown, the direction of the first steam nozzle 251 (as shown) Figure 4 The direction indicated by the middle arrow A can be the direction of steam injection. When it is pointed towards the surface to be cleaned in front of the cleaning equipment along the first direction of travel, the steam flow ejected from the first steam nozzle 251 can be concentrated on the ground area directly in front of the equipment's direction of travel. For example, as... Figure 4 As shown, the first steam nozzle 251 forms a predetermined angle α with the surface to be cleaned. For example, the angle α can be 45 degrees.

[0096] When the first steam nozzle is pointed at the surface to be cleaned at the front of the cleaning device along the first traveling direction, the steam emitted from the first steam nozzle can be directly observed by the user. This facilitates adjusting the direction of the cleaning device to ensure the steam is aimed at the user's desired area (such as a heavily soiled area), thus improving the user experience.

[0097] The first steam nozzle can also be pointed vertically at the surface to be cleaned. This vertical pointing allows the steam ejected from the first nozzle to act directly on the surface with maximum impact force, improving cleaning efficiency.

[0098] In one possible implementation, the first steam nozzle is configured to be directionally adjustable. For example, the direction of the first steam nozzle can be adjusted manually or by a drive component to flexibly adapt to different practical scenarios.

[0099] The first steam nozzle is optimized to point towards the surface to be cleaned, either directly in front of the cleaning device along its first direction of travel, or perpendicularly towards the surface. This allows the steam to act precisely and concentratedly on the target area in front of the device's direction of travel. When the steam nozzle points towards the surface to be cleaned, the user can more intuitively determine the area to be cleaned, thus accurately targeting heavily soiled areas, reducing steam dispersion, and improving the cleaning efficiency and effectiveness for stubborn stains. When the steam nozzle is perpendicular to the surface to be cleaned, the steam jet distance is shortened, and the impact force is enhanced, further improving the cleaning ability for heavily soiled areas.

[0100] When cleaning equipment performs self-cleaning, a separate steam generation system is typically required at the base station to achieve steam cleaning of the components. This configuration not only increases the manufacturing cost of the base station but also enhances its design complexity. Furthermore, existing steam nozzles on the cleaning equipment are usually fixed to the surface to be cleaned, making it difficult to achieve effective steam cleaning of the components.

[0101] In some embodiments, the method further includes at least one of the following: When the cleaning equipment is cleaning the surface to be cleaned, the first steam nozzle is controlled to spray steam towards the surface to be cleaned. When the cleaning equipment is self-cleaning, the first steam nozzle is controlled to spray steam towards the cleaning component of the cleaning equipment.

[0102] Users can select the cleaning mode of the cleaning equipment via buttons, the control panel, a mobile application, or voice commands. The controller then determines the cleaning mode, such as cleaning the surface to be cleaned or self-cleaning. Sensors inside the cleaning equipment can also determine the current cleaning mode by checking the equipment's status (such as whether it is located near a base station).

[0103] The cleaning equipment can adjust the physical angle or position of the first steam nozzle by means of a drive component (e.g., a micro motor, solenoid valve, or linkage mechanism) so that the first steam nozzle points to the surface to be cleaned or to the cleaning component.

[0104] When cleaning surfaces, the first steam nozzle can precisely target the surface, improving cleaning efficiency for heavily soiled areas and allowing users to accurately determine the steam coverage area. During self-cleaning, the first steam nozzle can target cleaning components of the cleaning equipment, such as cleaning roller brushes, reducing the need for additional steam generators or nozzles for the self-cleaning function. This simplifies the structure of the cleaning equipment, reducing production costs and design complexity. Furthermore, it improves the utilization efficiency of steam resources.

[0105] In some embodiments, the cleaning component includes a roller brush, and controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning device includes: During the self-cleaning process of the cleaning equipment, before the roller brush is dried, the first steam nozzle is controlled to spray steam towards the cleaning component of the cleaning equipment.

[0106] Roller brushes are used to scrub and absorb stains, and are typically made of absorbent materials such as microfiber or nylon bristles. During the self-cleaning process, the cleaning equipment can first clean the roller brush with a cleaning solution (water from a clean water tank) and then perform a drying process. The drying process can include spin-drying, hot air drying, or ironing.

[0107] The controller can direct the first steam nozzle to point at the roller brush in self-cleaning mode and spray steam onto the roller brush before the drying action. By controlling the first steam nozzle to spray steam onto the spun-dry roller brush, the steam can act more directly and effectively deep into the roller brush fibers, fully utilizing the high temperature and high pressure characteristics of the steam to improve the cleaning effect of the roller brush.

[0108] In some embodiments, the cleaning device includes a suction component, and the method further includes: During the process of controlling the steam generating component to discharge steam to the cleaning component, the suction component is controlled to shut down.

[0109] In some embodiments, the cleaning device includes a suction component, and the method further includes: During the process of controlling the steam generating component to discharge steam to the cleaning component, the suction component is controlled to shut down.

[0110] In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of controlling the steam generating assembly to discharge steam to the roller brush, the roller brush is controlled to rotate at a first rotational speed, wherein the first rotational speed is less than a second rotational speed, and the second rotational speed is the rotational speed of the roller brush during the drying operation.

[0111] In one possible implementation, the first rotational speed can be a lower speed specifically designed for self-cleaning, and the second rotational speed is a higher speed used by the cleaning device in normal operating mode (i.e. when cleaning the surface to be cleaned).

[0112] Rotating the roller brush at a speed lower than the normal cleaning speed allows the roller brush to remain in the steam for a longer time, enabling the steam to penetrate deeper into the brush bristles, thereby improving the cleaning efficiency of the steam and effectively removing stubborn dirt attached to the roller brush.

[0113] In some embodiments, the method further includes: controlling the suction component of the cleaning device to perform suction using a first power, wherein the first power is less than a second power, and the second power is the power used by the suction component when the cleaning device cleans the surface to be cleaned.

[0114] In one possible implementation, the first power is a lower suction power specifically designed for self-cleaning, while the second power is a higher suction power used by the cleaning device in normal operating mode (i.e., when cleaning the surface to be cleaned).

[0115] By controlling the suction component to use a lower first power than normal cleaning power, or by completely stopping the suction component, the premature removal of steam from the cleaning area can be reduced, allowing the steam to act on the roller brush for a longer period of time, thereby further enhancing the cleaning effect of the steam.

[0116] In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of the first steam nozzle spraying steam at the cleaning component of the cleaning equipment, the roller brush is controlled to rotate alternately in both directions.

[0117] Here, the direction of rotation of the brush in the forward direction can be the same as the direction of rotation used when the cleaning equipment moves in the first direction of travel, while the direction of rotation of the brush in the reverse direction is opposite to the direction of rotation of the brush in the forward direction.

[0118] By rotating the roller brush in both directions, different parts of the brush can come into contact with the steam, thereby enhancing the cleaning effect of the steam.

[0119] In some embodiments, the first steam ejection assembly includes: a drive component for switching the direction of the first steam nozzle; The step of controlling the first steam nozzle to spray steam toward the surface to be cleaned includes: controlling the driving component to drive the first steam nozzle to point toward the surface to be cleaned, so as to spray steam onto the surface to be cleaned; and / or The step of controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning equipment includes: controlling the driving component to drive the first steam nozzle to point toward the cleaning component, so as to spray steam onto the cleaning component.

[0120] The driving component is an actuator used to change the direction of the first steam nozzle. The driving component may include at least one of the following: a micro motor, a solenoid valve, or a linkage mechanism. For example, the steam injection direction can be changed by controlling the micro motor to drive the first steam nozzle to rotate or oscillate.

[0121] The control drive component drives the first steam nozzle to point at the surface to be cleaned or the part to be cleaned, in order to adapt to different working scenarios (e.g., cleaning the ground or self-cleaning the cleaning part itself), and guides the steam generated by the steam generating component to the target area, so as to achieve effective utilization of steam and cleaning effect.

[0122] like Figure 4 and Figure 5 As shown, when the controller detects that the user has activated the cleaning mode or self-cleaning mode, the controller can send corresponding control commands to the drive component to control the drive component to perform corresponding mechanical actions, adjusting the first steam nozzle 251 to point towards the surface to be cleaned (e.g., ...). Figure 4(as shown) or adjust the first steam nozzle 251 to point towards the cleaning component (such as... Figure 5 As shown, Figure 5 for Figure 1 A partial cross-sectional view of the floor brush assembly 2 is shown.

[0123] When the cleaning equipment is cleaning a surface, the control drive unit directs the first steam nozzle towards the surface, enabling precise steam application to the target area and improving the cleaning efficiency for localized dirt and steam utilization. During self-cleaning, the control drive unit directs the first steam nozzle towards the cleaning components, allowing the cleaning components (such as roller brushes) to directly receive steam cleaning without the need for an additional steam generator, reducing the equipment's structural complexity and manufacturing costs. This enhances the user experience and the equipment's level of intelligence.

[0124] In some embodiments, the first steam ejection assembly includes a control valve, and the first steam nozzle includes a first sub-nozzle pointing toward the surface to be cleaned and a second sub-nozzle pointing toward the cleaning component; The method of controlling the first steam nozzle to spray steam toward the surface to be cleaned includes: controlling a control valve to shut off the steam passage between the steam generating assembly and the second sub-nozzle, and opening the steam passage between the steam generating assembly and the first sub-nozzle, so as to spray steam toward the surface to be cleaned through the first sub-nozzle; and / or The method of controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning equipment includes: controlling a control valve to shut off the steam passage between the steam generating assembly and the first sub-nozzle, and opening the steam passage between the steam generating assembly and the second sub-nozzle, so as to spray steam toward the cleaning component through the second sub-nozzle.

[0125] Here, the control valve can be used to regulate, control, or switch the flow of fluids (such as steam). In cleaning equipment, this control valve can take many forms; for example, it can be a solenoid valve (such as a two-position three-way solenoid valve, a four-way solenoid valve, etc.). The controller controls the opening and closing of the valve core via an electrical signal, thereby switching the steam path.

[0126] Figure 6 for Figure 1 A partial structural diagram of the floor brush component 2 is shown below. Figure 6As shown, the first steam nozzle 251 may include two independent steam outlets: a first sub-nozzle 2511 and a second sub-nozzle 2512. The first sub-nozzle 2511 is used to spray steam onto the surface to be cleaned, such as a floor. The second sub-nozzle 2512 is used to spray steam onto the cleaning components of the cleaning equipment, such as a roller brush. This allows the steam to be precisely sprayed onto the target area via different paths according to different cleaning needs, reducing the complexity of physical steering required for a single nozzle.

[0127] When the cleaning equipment needs to clean the floor and the surface is waiting to be cleaned, the controller can send a command to the control valve, causing the control valve to close the steam passage connecting the steam generator and the second sub-nozzle, while simultaneously opening the steam passage connecting the steam generator and the first sub-nozzle. All the steam generated by the steam generator can then be ejected through the first sub-nozzle, directly acting on the surface to be cleaned, achieving efficient floor cleaning. This ensures precise steam delivery, reducing steam waste and accidental spraying.

[0128] When the cleaning equipment enters self-cleaning mode and requires steam cleaning of cleaning components such as the roller brush, the controller sends a command to the control valve. This command closes the steam passage connecting the steam generator to the first sub-nozzle, while simultaneously opening the steam passage connecting the steam generator to the second sub-nozzle. The steam generated by the steam generator is then ejected through the second sub-nozzle, directly acting on the cleaning components for high-temperature steam cleaning, effectively removing dirt and bacteria adhering to them. This process achieves internal steam cleaning of the cleaning components without the need for an additional steam generator.

[0129] By combining control valves, a first sub-nozzle, and a second sub-nozzle, the structural complexity and high cost associated with traditional mechanical drive components can be reduced. The cleaning equipment can flexibly and precisely achieve directional steam injection, effectively overcoming the limitations of mechanical drive switching and improving user experience and overall equipment performance.

[0130] Example 2 When cleaning equipment performs self-cleaning, a separate steam generation system is typically required at the base station to achieve steam cleaning of the components. This configuration not only increases the manufacturing cost of the base station but also enhances its design complexity. Furthermore, existing steam nozzles on the cleaning equipment are usually fixed to the surface to be cleaned, making it difficult to achieve effective steam cleaning of the components.

[0131] This application provides a control method for a cleaning device, the cleaning device including: a steam generating component for generating steam, a first steam ejection component and a second steam ejection component, wherein the number of first steam nozzles in the first steam ejection component is less than the number of second steam nozzles in the second steam ejection component; like Figure 7 As shown, the method includes: Step 701: When the cleaning equipment is self-cleaning, control the first steam nozzle to spray steam towards the cleaning component of the cleaning equipment.

[0132] Here, the composition and structure of the cleaning equipment are as shown in any of the above embodiments, and will not be repeated here.

[0133] Users can select the cleaning mode of the cleaning equipment via buttons, the control panel, a mobile application, or voice commands. The controller then determines the cleaning mode, such as cleaning the surface to be cleaned or self-cleaning. Sensors inside the cleaning equipment can also determine the current cleaning mode by checking the equipment's status (such as whether it is located near a base station).

[0134] When the cleaning equipment starts its self-cleaning program, the controller activates the first steam ejection assembly, oriented the first steam nozzle toward the cleaning components of the cleaning equipment, such as the roller brush. Steam generated by the steam generating assembly is delivered to the first steam nozzle via the first steam ejection assembly and sprayed onto the surface of the cleaning components, thereby achieving direct steam cleaning of the cleaning components.

[0135] Thus, by effectively utilizing the existing steam generating components and the first steam ejection component of the cleaning equipment, steam cleaning of the cleaning components can be completed without an additional steam device in self-cleaning mode. Because the number of first steam nozzles is small, the steam injection direction is easier to control precisely, allowing steam to be concentrated on target areas such as the roller brush, improving cleaning efficiency. Simultaneously, it reduces the need for additional steam generating devices in the base station, simplifying the overall equipment structure and reducing production design complexity and manufacturing costs. Furthermore, during the self-cleaning process, this application achieves high-temperature cleaning and sterilization of the cleaning components by re-spraying steam onto the cleaning components, preventing odor from the roller brush and effectively improving the cleaning effect.

[0136] In some embodiments, the method further includes: When the cleaning equipment is cleaning the surface to be cleaned, the first steam nozzle is controlled to spray steam towards the surface to be cleaned.

[0137] Users can select the cleaning mode of the cleaning equipment via buttons, the control panel, a mobile application, or voice commands. The controller then determines the cleaning mode, such as cleaning the surface to be cleaned or self-cleaning. Sensors inside the cleaning equipment can also determine the current cleaning mode by checking the equipment's status (such as whether it is located near a base station).

[0138] The cleaning equipment can adjust the physical angle or position of the first steam nozzle by means of a drive component (e.g., a micro motor, solenoid valve, or linkage mechanism) so that the first steam nozzle points to the surface to be cleaned or to the cleaning component.

[0139] When the cleaning equipment is cleaning the surface, the controller can direct the first steam nozzles to spray steam onto the surface. The first steam nozzles are typically fewer in number, and their steam stream has higher concentration and directionality, allowing for more precise application of steam to heavily soiled areas. Compared to using a larger number of second steam nozzles for broad coverage, the directional spraying of the first steam nozzles improves the cleaning efficiency and effectiveness for stubborn stains.

[0140] In some embodiments, the cleaning component includes a roller brush, and controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning device includes: During the self-cleaning process of the cleaning equipment, before the roller brush is dried, the first steam nozzle is controlled to spray steam towards the cleaning component of the cleaning equipment.

[0141] Roller brushes are used to scrub and absorb stains, and are typically made of absorbent materials such as microfiber or nylon bristles. During the self-cleaning process, the cleaning equipment can first clean the roller brush with a cleaning solution (water from a clean water tank) and then perform a drying process. The drying process can include spin-drying, hot air drying, or ironing. The controller can direct the first steam nozzle to point at the roller brush in self-cleaning mode and spray steam onto the spun-dry roller brush before the drying action, so that the steam can act more directly and effectively on the deep fibers of the roller brush, giving full play to the high temperature and high pressure characteristics of the steam and improving the cleaning effect of the roller brush.

[0142] In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of controlling the steam generating assembly to discharge steam to the roller brush, the roller brush is controlled to rotate at a first rotational speed, wherein the first rotational speed is less than a second rotational speed, and the second rotational speed is the rotational speed of the roller brush during the drying operation.

[0143] In one possible implementation, the first rotational speed can be a lower speed specifically designed for self-cleaning, and the second rotational speed is a higher speed used by the cleaning device in normal operating mode (i.e. when cleaning the surface to be cleaned).

[0144] Rotating the roller brush at a speed lower than the normal cleaning speed allows the roller brush to remain in the steam for a longer time, enabling the steam to penetrate deeper into the brush bristles, thereby improving the cleaning efficiency of the steam and effectively removing stubborn dirt attached to the roller brush.

[0145] In one possible implementation, the first power is a lower suction power specifically designed for self-cleaning, while the second power is a higher suction power used by the cleaning device in normal operating mode (i.e., when cleaning the surface to be cleaned).

[0146] By controlling the suction component to use a lower first power than normal cleaning power, or by completely stopping the suction component, the premature removal of steam from the cleaning area can be reduced, allowing the steam to act on the roller brush for a longer period of time, thereby further enhancing the cleaning effect of the steam.

[0147] In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of the first steam nozzle spraying steam at the cleaning component of the cleaning equipment, the roller brush is controlled to rotate alternately in both directions.

[0148] Here, the direction of rotation of the brush in the forward direction can be the same as the direction of rotation used when the cleaning equipment moves in the first direction of travel, while the direction of rotation of the brush in the reverse direction is opposite to the direction of rotation of the brush in the forward direction.

[0149] By rotating the roller brush in both directions, different parts of the brush can come into contact with the steam, thereby enhancing the cleaning effect of the steam.

[0150] In some embodiments, the first steam ejection assembly includes: a drive component for switching the direction of the first steam nozzle; The step of controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning equipment includes: controlling the driving component to drive the first steam nozzle to point toward the cleaning component, so as to spray steam onto the cleaning component.

[0151] In some embodiments, the method further includes When the cleaning equipment is cleaning the surface to be cleaned, the drive component is controlled to drive the first steam nozzle to point at the surface to be cleaned so as to spray steam onto the surface to be cleaned.

[0154] When the controller detects that the user has activated the cleaning mode or self-cleaning mode, it can send corresponding control commands to the drive unit to control the drive unit to perform corresponding mechanical actions, adjusting the first steam nozzle to point towards the surface to be cleaned (e.g., ...). Figure 4 (as shown) or adjust the first steam nozzle to point towards the cleaning component (such as...) Figure 5 As shown, Figure 5 for Figure 1 A partial cross-sectional view of the floor brush assembly 2 is shown.

[0156] In some embodiments, the first steam ejection assembly includes a control valve, and the first steam nozzle includes a first sub-nozzle pointing toward the surface to be cleaned and a second sub-nozzle pointing toward the cleaning component; The method of controlling the first steam nozzle to spray steam toward the cleaning component of the cleaning equipment includes: controlling a control valve to shut off the steam passage between the steam generating assembly and the first sub-nozzle, and opening the steam passage between the steam generating assembly and the second sub-nozzle, so as to spray steam toward the cleaning component through the second sub-nozzle.

[0157] In some embodiments, the method further includes: When the cleaning equipment is cleaning the surface to be cleaned, the control valve shuts off the steam passage between the steam generating assembly and the second sub-nozzle, and opens the steam passage between the steam generating assembly and the first sub-nozzle, so that steam is sprayed onto the surface to be cleaned through the first sub-nozzle.

[0158] Here, the control valve can be used to regulate, control, or switch the flow of fluids (such as steam). In cleaning equipment, this control valve can take many forms; for example, it can be a solenoid valve (such as a two-position three-way solenoid valve, a four-way solenoid valve, etc.). The controller controls the opening and closing of the valve core via an electrical signal, thereby switching the steam path.

[0159] Figure 6 for Figure 1 A partial structural diagram of the floor brush component 2 is shown below. Figure 6As shown, the first steam nozzle can include two independent steam outlets: a first sub-nozzle and a second sub-nozzle. The first sub-nozzle is used to spray steam onto the surface to be cleaned, such as a floor. The second sub-nozzle is used to spray steam onto the cleaning components of the cleaning equipment, such as a roller brush. This allows the steam to be precisely sprayed onto the target area via different paths according to different cleaning needs, reducing the complexity of physical steering required by a single nozzle.

[0160] When the cleaning equipment needs to clean the floor and the surface is waiting to be cleaned, the controller can send a command to the control valve, causing the control valve to close the steam passage connecting the steam generator and the second sub-nozzle, while simultaneously opening the steam passage connecting the steam generator and the first sub-nozzle.

The cleaning equipment can flexibly and precisely achieve directional steam injection, effectively overcoming the limitations of mechanical drive switching and improving user experience and overall equipment performance.

[0163] Example 3 When cleaning equipment performs self-cleaning, a separate steam generation system is typically required at the base station to achieve steam cleaning of the components. This configuration not only increases the manufacturing cost of the base station but also enhances its design complexity. Furthermore, existing steam nozzles on the cleaning equipment are usually fixed to the surface to be cleaned, making it difficult to achieve effective steam cleaning of the components.

[0164] This application provides a control method for a cleaning device, the cleaning device including: a cleaning component, a steam generating component for generating steam, a pumping component, and a spraying component, wherein the pumping component is used to pump cleaning liquid to the spraying component so as to spray cleaning liquid onto the cleaning component through the cleaning liquid nozzle of the spraying component; like Figure 8As shown, the method includes: Step 801: When the cleaning equipment is performing self-cleaning, control the pumping assembly to stop pumping cleaning liquid to the spraying assembly, and control the steam generating assembly to discharge steam to the spraying assembly so as to spray steam to the cleaning component through the cleaning liquid nozzle of the spraying assembly.

[0165] Here, the control method can be executed by the controller of the cleaning equipment.

[0166] Cleaning components are parts of cleaning equipment that come into direct contact with the surface to be cleaned or with their own dirt and perform the cleaning action, such as roller brushes, brush heads, or mops.

[0167] The steam generating components are as described in any of the above embodiments and will not be repeated here.

[0168] A pump-liquid assembly can be a device in cleaning equipment used to deliver cleaning fluid (such as water, or a mixture of water and detergent) from a water tank to a spray assembly. The pump-liquid assembly may include a pump body, a motor, and fluid lines to achieve precise delivery of the cleaning fluid.

[0169] A liquid spraying assembly can refer to a device in cleaning equipment used to spray cleaning fluid or vapor onto a target area. A liquid spraying assembly may include nozzles, flow lines, and connecting structures to achieve directional liquid spraying.

[0170] The cleaning fluid nozzle may include an outlet on the spray assembly for spraying the cleaning fluid.

[0171] Self-cleaning can refer to the cleaning and maintenance of cleaning equipment's own cleaning components and / or pipes after completing the task of cleaning the external environment, in order to keep the cleaning equipment clean and hygienic.

[0172] Users can select the cleaning mode of the cleaning equipment via buttons, the control panel, a mobile application, or voice commands. The controller then determines the cleaning mode, such as cleaning the surface to be cleaned or self-cleaning. Sensors inside the cleaning equipment can also determine the current cleaning mode by checking the equipment's status (such as whether it is located near a base station).

[0173] The pump assembly delivers cleaning fluid from the reservoir to the spray assembly. The spray assembly then sprays the cleaning fluid onto the cleaning components or surfaces to be cleaned through its nozzles. When cleaning a surface, the pump assembly can pump cleaning fluid into the spray assembly and spray it onto the cleaning components through the nozzles to assist in the cleaning process.

[0174] In one possible implementation, the steam generating component can be used to supply steam to the steam nozzle of the steam ejection component when the cleaning equipment is cleaning the surface to be cleaned, so as to eject steam onto the surface to be cleaned.

[0175] In response to the self-cleaning function of the cleaning equipment, the controller can control the pump assembly to stop pumping cleaning fluid to the spray assembly. Stopping the pump assembly from pumping cleaning fluid can be achieved in several ways. For example, the power supply to the pump assembly can be directly cut off, causing it to stop operating; or, a valve can be installed in the fluid path between the pump assembly and the spray assembly, and the flow of cleaning fluid can be blocked by closing this valve.

[0176] Simultaneously, the controller can control the steam generating assembly to discharge steam to the spraying assembly. The steam generating assembly is activated by supplying power to its heating element, heating the water inside and generating steam. The generated steam is then guided to the spraying assembly. Steam guidance can be achieved through a separate steam line, activated in self-cleaning mode, directly delivering steam to the spraying assembly. In another implementation, the steam generating assembly can be connected to the spraying assembly via a shared channel, configured to prioritize steam delivery in self-cleaning mode. Thus, the cleaning fluid nozzles of the spraying assembly can spray steam onto the cleaning components. The cleaning fluid nozzles, originally used for spraying cleaning fluid, are reused in this embodiment to spray steam. The steam is guided through channels within the spraying assembly to the cleaning fluid nozzles and exits from them, directly acting on the cleaning components. For example, when the cleaning component is a roller brush, steam can be sprayed onto the roller brush surface to heat and soften the dirt.

[0177] Figure 9 and Figure 10 for Figure 1 A partial schematic diagram of the floor brush component 2 shown.

[0178] In one possible implementation, such as Figure 9 As shown, the cleaning fluid nozzle 261 can be disposed on the inner wall of the main brush chamber facing the roller brush 23.

[0179] In one possible implementation, such as Figure 10 As shown, the cleaning fluid nozzle 261 can be disposed inside the roller brush 23. The cleaning fluid nozzle 261 can be connected to a steam generating component or a pumping component inside the floor brush housing 2 through a channel disposed on the roller brush shaft.

[0180] By controlling the pump assembly to stop pumping cleaning fluid to the spray assembly and controlling the steam generator to discharge steam to the spray assembly during self-cleaning of the cleaning equipment, steam is sprayed onto the cleaning components through the cleaning fluid nozzles of the spray assembly. This effectively reuses the existing spray assembly and cleaning fluid nozzles in the cleaning equipment for steam injection, eliminating the need for a separate steam generator system or dedicated steam nozzles at the base station, and also eliminating the need for a separate set of dedicated steam nozzles to spray steam onto the cleaning components, thus reducing the manufacturing cost and design complexity of the cleaning equipment. Furthermore, by spraying steam onto the cleaning components during the self-cleaning process, this application achieves high-temperature cleaning and high-temperature sterilization of the cleaning components.

[0181] In some embodiments, the cleaning device includes a control valve; controlling the pumping assembly to stop pumping cleaning fluid to the spraying assembly and controlling the steam generating assembly to discharge steam to the spraying assembly includes: controlling the control valve to shut off the passage between the pumping assembly and the spraying assembly, and opening the passage between the steam generating assembly and the spraying assembly to spray steam to the cleaning components through the cleaning fluid nozzle.

[0182] Here, the control valve can be used to regulate, control, or switch the flow of fluids (such as steam and / or liquids). In cleaning equipment, the control valve can be implemented in various forms; for example, the control valve can be a solenoid valve (such as a two-position three-way solenoid valve). The controller controls the opening and closing of the valve spool via an electrical signal, thereby switching the steam and / or liquid passage.

[0183] For example, such as Figure 11 As shown, a steam generating assembly may include a steam pump, a pressure relief valve, a boiler, a scale box, valves, and pipes. The steam pump draws water from the clean water tank, which passes through the pressure relief valve to the boiler to generate steam. The steam then passes through the scale box and valves before reaching the control valve. The pump-liquid assembly can also draw water from the clean water tank, which can be injected into the control valve. During self-cleaning of the cleaning equipment, the controller can switch the cleaning fluid path to a steam path via the control valve. The controller can also control the control valve to shut off the passage between the pump-liquid assembly and the spray assembly, thus preventing the cleaning fluid from flowing from the pump-liquid assembly to the spray assembly, thereby reducing the mixing or residue of cleaning fluid during steam injection.

[0184] When the cleaning equipment is self-cleaning, the controller can open the passage between the steam generating component and the liquid spraying component.

[0185] The controller can control the control valve to open the passage between the steam generating assembly and the liquid spraying assembly, allowing the steam generated by the steam generating assembly to flow from the steam generating assembly to the liquid spraying assembly. In this way, the cleaning equipment can use the cleaning liquid nozzle of the liquid spraying assembly to spray steam onto the cleaning parts, eliminating the need for a separate dedicated nozzle for steam spraying and reusing the cleaning liquid nozzle.

[0186] Steam is emitted from the cleaning fluid nozzles using the spray assembly via a control valve, eliminating the need for additional dedicated nozzles and simplifying the equipment structure. The coordinated on / off operation of the control valve enables seamless switching between the cleaning fluid and steam pathways, reducing manufacturing costs and design complexity.

[0187] In some embodiments, the cleaning component includes a roller brush, and the control of the steam generating assembly to discharge steam to the spraying assembly includes: During the self-cleaning process of the cleaning equipment, before the drying action is performed on the roller brush, the steam generating component is controlled to discharge steam to the spraying component.

[0188] Roller brushes are used to scrub and absorb stains, and are typically made of absorbent materials such as microfiber or nylon bristles. During the self-cleaning process, the cleaning equipment can first clean the roller brush with a cleaning solution (water from a clean water tank) and then perform a drying process. The drying process can include spin-drying, hot air drying, or ironing.

[0189] The controller can control the steam generating component to discharge steam to the spraying component and spray steam onto the roller brush before the drying action. By controlling the steam generating component to spray steam onto the roller brush, the steam can act more directly and effectively deep into the roller brush fibers, fully utilizing the high temperature and high pressure characteristics of the steam and improving the cleaning effect of the roller brush.

[0190] In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of controlling the steam generating component to output steam, the roller brush is controlled to rotate at a first rotational speed, wherein the first rotational speed is less than a second rotational speed, and the second rotational speed is the rotational speed of the roller brush during the drying operation.

[0191] In some embodiments, the cleaning device includes a suction component, and the method further includes: During the process of controlling the steam generating component to discharge steam to the liquid spraying component, the suction component is controlled to shut down.

[0192] In one possible implementation, the first rotational speed can be a lower speed specifically designed for self-cleaning, and the second rotational speed is a higher speed used by the cleaning device in normal operating mode (i.e. when cleaning the surface to be cleaned).

[0193] Rotating the roller brush at a speed lower than the normal cleaning speed allows the roller brush to remain in the steam for a longer time, enabling the steam to penetrate deeper into the brush bristles, thereby improving the cleaning efficiency of the steam and effectively removing stubborn dirt attached to the roller brush.

[0194] In some embodiments, the method further includes: controlling the suction component of the cleaning device to perform suction using a first power, wherein the first power is less than a second power, and the second power is the power used by the suction component when the cleaning device cleans the surface to be cleaned.

[0195] In one possible implementation, the first power is a lower suction power specifically designed for self-cleaning, while the second power is a higher suction power used by the cleaning device in normal operating mode (i.e., when cleaning the surface to be cleaned).

[0196] By controlling the suction component to use a lower first power than normal cleaning power, or by completely stopping the suction component, the premature removal of steam from the cleaning area can be reduced, allowing the steam to act on the roller brush for a longer period of time, thereby further enhancing the cleaning effect of the steam.

[0197] In some embodiments, the cleaning device further includes: a steam ejection assembly, the steam ejection assembly including at least one steam nozzle; the method further includes: When the cleaning equipment is cleaning the surface to be cleaned, the steam generating component is controlled to discharge steam to the steam spraying component so as to spray steam onto the surface to be cleaned through the steam nozzle.

[0198] A steam ejection assembly can be a structure in a cleaning device used to direct and spray steam onto the surface to be cleaned.

[0199] The steam nozzle is the final steam output port of the steam ejection assembly. The shape, size, and number of steam nozzle openings can be optimized according to the required steam ejection pattern and cleaning effect.

[0200] In one possible implementation, the steam nozzle can be configured to point towards the surface to be cleaned. This could be perpendicular to the surface, and / or at a predetermined angle (e.g., 45 degrees). The predetermined angle can refer to the angle between the steam nozzle and the surface to be cleaned. The predetermined angle can be any angle between 20 and 60 degrees; preferably, it can be 45°.

[0201] In one possible implementation, there can be multiple steam nozzles to allow the steam to cover a wider cleaning area.

[0202] In one possible implementation, there could be a steam nozzle used to generate a high-pressure steam jet to enhance cleaning power.

[0203] When the cleaning equipment is cleaning the surface to be cleaned, the controller of the cleaning equipment can control the steam generated by the steam generating component to be directed to the steam ejection component. For example... Figure 12As shown, the controller can control the valves (e.g., three-way solenoid valves) in the steam generation unit to allow steam to flow from the steam generation assembly to the steam ejection assembly, and then be ejected from the steam nozzle. In this way, the existing steam generation assembly in the cleaning equipment can be effectively utilized, avoiding the need to set up an additional separate steam generation system for cleaning the surface to be cleaned.

[0204] In this way, the steam generated by the steam generator can be used to clean the surface to be cleaned, and to clean the roller brush during self-cleaning. This achieves component reuse, reducing the manufacturing cost and design complexity of the cleaning equipment. In some embodiments, the cleaning component includes a roller brush, and the method further includes: During the process of controlling the steam generating component to discharge steam to the liquid spraying component, the roller brush is controlled to rotate alternately in both directions.

[0205] Here, the direction of rotation of the brush in the forward direction can be the same as the direction of rotation used when the cleaning equipment moves in the first direction of travel, while the direction of rotation of the brush in the reverse direction is opposite to the direction of rotation of the brush in the forward direction.

[0206] By rotating the roller brush in both directions, different parts of the brush can come into contact with the steam, thereby enhancing the cleaning effect of the steam.

[0207] In some embodiments, the method further includes: During the cleaning process of the cleaning equipment, the pumping component is controlled to pump cleaning liquid into the spraying component, and the steam generating component is controlled to discharge steam into the spraying component to heat the cleaning liquid.

[0208] While the pump assembly delivers the cleaning fluid, the controller can control the steam generator to produce and deliver steam to the spray assembly, allowing the steam to exchange heat with or directly mix with the cleaning fluid, thereby increasing the temperature of the cleaning fluid. For example, the cleaning fluid and steam can be mixed at a control valve to achieve rapid heating. By using a higher-temperature cleaning fluid, the dissolution rate of stains can be increased, improving cleaning efficiency.

[0209] When the pumping unit pumps cleaning fluid to the spraying unit, the controller can control the steam generating unit to stop supplying steam to the spraying unit. This can be achieved, for example, by closing the steam passage valve between the steam generating unit and the spraying unit, or by directly stopping the heating function of the steam generating unit, thus preventing it from generating steam.

[0210] Thus, the cleaning equipment offers two flexible cleaning modes when cleaning surfaces: heated or unheated cleaning solution. Higher-temperature cleaning solutions dissolve grease and stubborn stains more effectively and accelerate the chemical reaction of the cleaning agent, significantly improving cleaning efficiency and stain removal power. Room-temperature cleaning solutions are suitable for light stains or surfaces sensitive to high temperatures. The cleaning equipment can flexibly select the appropriate cleaning method based on different cleaning needs and stain types, enhancing its adaptability and improving the user experience.

[0211] In some embodiments, the steam ejection assembly includes at least a first steam ejection assembly, the first steam ejection assembly being controllably directed toward the surface to be cleaned or the cleaning component of the cleaning device; the method further includes: When the cleaning device is self-cleaning, the first steam ejection component is controlled to eject steam toward the cleaning component of the cleaning device.

[0212] In one possible implementation, multiple steam ejection assemblies can exist physically independently. The steam generating assembly can direct the generated steam to any of the steam ejection assemblies.

[0213] In one possible implementation, the steam generating component selects one of a plurality of steam ejection components to output steam.

[0214] In one possible implementation, the steam ejection assembly includes a first steam ejection assembly and a second steam ejection assembly, wherein the number of first steam nozzles in the first steam ejection assembly is less than the number of second steam nozzles in the second steam ejection assembly.

[0215] In some embodiments, the cleaning device includes a floor brush assembly; Along the first direction of travel, the first steam nozzle points towards the surface to be cleaned at the front of the floor brush assembly; or; The first steam nozzle is pointed vertically at the surface to be cleaned.

[0216] In one possible implementation, the second steam nozzle is pointed vertically toward the surface to be cleaned.

[0217] The cleaning equipment can adjust the physical angle or position of the first steam nozzle via a drive component (e.g., a micro motor, solenoid valve, or linkage mechanism) to point the first steam nozzle at the surface to be cleaned or at the part to be cleaned. Alternatively, the first steam nozzle may have multiple outlets (e.g., a first sub-steam nozzle and a second sub-steam nozzle), and the steam flow can be switched to different outlets by controlling a valve, thereby achieving the goal of pointing the steam nozzle at the surface to be cleaned or at the part to be cleaned.

[0218] like Figure 4 As shown, the first steam nozzle 251 can be adjusted to point towards the surface to be cleaned. Figure 5As shown, the first steam nozzle 251 can be adjusted to point towards the cleaning component (roller brush). For example... Figure 4 and Figure 5 As shown, the second steam nozzle 241 can be configured to point towards the surface to be cleaned, and multiple second steam nozzles can be arranged along the axial direction of the roller brush 23.

[0219] When cleaning surfaces, the first steam nozzle can precisely target the surface, improving cleaning efficiency for heavily soiled areas and allowing users to accurately determine the steam coverage area. During self-cleaning, the first steam nozzle can target the cleaning components of the cleaning equipment, such as steam cleaning rollers, reducing the need for additional steam generators or nozzles for the self-cleaning function. This simplifies the structure of the cleaning equipment, reducing production costs and design complexity. Furthermore, it improves the utilization efficiency of steam resources.

[0220] In some embodiments, the method further includes: When the cleaning equipment is self-cleaning, the steam generating component is controlled to discharge steam to the first steam ejection component, so as to spray steam onto the cleaning component through the first steam nozzle.

[0221] When the cleaning equipment enters the self-cleaning mode, the controller can direct the steam generated by the steam generating component to the pipe of the first steam ejection component, so that the first steam nozzle can effectively eject steam to the cleaning component.

[0222] For example, such as Figure 13 As shown, the controller can selectively direct steam to control valve 1 or control valve 2 via a valve. Control valve 1 is used by the controller to select whether cleaning liquid or steam is sprayed out through the cleaning liquid nozzle; control valve 2 is used by the controller to select whether steam is sprayed out through the first steam nozzle or the second steam nozzle.

[0223] Here, control valve 1, control valve 2, and valve can be individual components or functional modules within a single component. For example, control valve 1, control valve 2, and valve can each be an independent two-position three-way valve; or control valve 1 can be an independent two-position three-way valve, while control valve 2 and valve can be combined into a single three-position four-way valve.

[0224] Combination Figure 6 The cleaning equipment control method may include at least one of the following: When the cleaning device is performing self-cleaning, the steam generating component is controlled to discharge steam to the first steam ejection component so as to eject steam to the cleaning component through the first steam nozzle (when the first steam nozzle is controlled to point towards the cleaning component). When the cleaning equipment is self-cleaning, the controller can control the steam generating component to discharge steam to the spraying component, so as to spray steam to the cleaning component through the cleaning liquid nozzle of the spraying component; When the cleaning equipment is cleaning the surface to be cleaned, the controller can control the steam generating component to discharge steam to the first steam ejecting component, so as to spray steam onto the surface to be cleaned through the first steam nozzle (when the first steam nozzle is controlled or uncontrolled and points towards the cleaning component). When the cleaning device is cleaning the surface to be cleaned, the controller can control the steam generating component to discharge steam to the second steam ejection component, so as to spray steam onto the surface to be cleaned through the second steam nozzle.
