Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0038] Currently, cleaning equipment uses a single cleaning step, such as simply outputting steam, cleaning liquid, or foam to the target area and then mopping. However, different stains in the target area require different cleaning strategies. A single cleaning step is insufficient to meet the cleaning needs of different application scenarios, has limited cleaning ability, and is difficult to remove stubborn stains.

[0039] To address the aforementioned issues, this application provides a control method and cleaning equipment for a cleaning device. By employing a cleaning strategy, the cleaning steps of outputting steam to the target area are flexibly combined with various other cleaning steps to achieve synergistic operation of multiple cleaning steps, thereby improving cleaning efficiency and effectiveness and removing stubborn stains.

[0040] The subject executing the control method for the cleaning equipment provided in this application may be, for example, a cleaning device such as a sweeping robot, a sweeping and mopping robot, a floor washing robot, or a pool cleaning robot.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] This application provides a control method for a cleaning device. The cleaning device includes a steam cleaning unit, and further includes at least one of a cleaning liquid cleaning unit and a foam cleaning unit.

[0043] The system comprises three units: a steam cleaning unit to generate high-temperature steam and output it to the target area; a cleaning liquid cleaning unit to store and transport cleaning liquid and output it to the target area; and a foam cleaning unit to mix the cleaning liquid with air to form foam and output it to the target area. The steam cleaning unit, cleaning liquid cleaning unit, and foam cleaning unit can each use different structural modules to output steam, cleaning liquid, or foam respectively, or they can use the same structural module to perform the functions of outputting steam, cleaning liquid, or foam.

[0044] Control methods include: S1. Clean the target area according to the cleaning strategy.

[0045] The cleaning strategy includes the step of controlling the steam cleaning unit to output steam to the target area, and at least one of the following cleaning steps: controlling the cleaning liquid cleaning unit to output cleaning liquid to the target area; controlling the foam cleaning unit to output foam to the target area.

[0046] Specifically, the cleaning strategy is a pre-set cleaning plan or a cleaning scheme generated based on the contamination status of the target area, which includes control rules for the start-up, shutdown, working sequence, and output of the steam cleaning unit, cleaning liquid cleaning unit, or foam cleaning unit.

[0047] The cleaning strategy can first control the steam cleaning unit to output steam to the target area, then control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area; alternatively, it can first control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area, then control the steam cleaning unit to output steam to the target area.

[0048] By combining steam with cleaning liquid and foam, it is suitable for various cleaning scenarios such as common dust, heavy stains, and stubborn stains, improving cleaning efficiency and cleaning effect.

[0049] In some embodiments, the cleaning device further includes a wet cleaning element for mopping the target area, for example by rubbing the target area with a roller or mop to achieve a cleaning effect.

[0050] In heavily contaminated areas, such as kitchens, floors often have numerous stains that are difficult to remove once dried. While cleaning solutions or foams can soak and break down the stains, they require prolonged exposure and are not always completely dissolved, leaving some residue on the surface. High-temperature steam alone can only physically soften the stains; it is insufficient to break them down, making complete removal difficult.

[0051] To solve the problems in the above scenarios, such as Figure 1As shown, the cleaning strategy includes: S101, Control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area.

[0052] Specifically, in this embodiment, the cleaning liquid cleaning unit can be controlled to output cleaning liquid to the target area, or the foam cleaning unit can be controlled to output foam to the target area. Alternatively, the cleaning liquid cleaning unit can be controlled to output cleaning liquid to the target area first, and then the foam cleaning unit can be controlled to output foam to the target area. Or, the foam cleaning unit can be controlled to output foam to the target area first, and then the cleaning liquid cleaning unit can be controlled to output cleaning liquid to the target area. Or, the cleaning liquid cleaning unit and the foam cleaning unit can be controlled to output cleaning liquid and foam to the target area simultaneously.

[0053] Cleaning solutions can be chemical cleaners or ordinary water; hot water can also be obtained by heating the water. Cleaning solutions or foams can soak, coat, or chemically break down stains in the target area, reducing the adhesion between the stains and the surface, making subsequent cleaning steps easier and improving cleaning effectiveness. Depending on the type of stain, cleaning solutions, foams, or a combination of both can be flexibly selected to suit different cleaning scenarios.

[0054] S102, Control the steam cleaning unit to output steam to the target area.

[0055] Specifically, after the target area is treated with cleaning liquid or foam, the steam cleaning unit is controlled to continuously output high-temperature and high-pressure steam to the target area for further treatment of the stains.

[0056] High-temperature, high-pressure steam softens stains still adhering to the surface in the target area, enhancing the stain-removing activity of the cleaning solution or foam and improving cleaning efficiency. It also provides high-temperature, mite-removing, and odor-eliminating effects. The steam further moistens stains in the target area, reducing friction during subsequent mopping and improving cleaning results.

[0057] S103, Control the wet cleaning element to mop the target area.

[0058] Specifically, after the steam output to the target area is processed, the stains in the target area have been decomposed and softened. The target area is then physically wiped and mopped by wet cleaning elements, and the stains in the target area are removed by friction.

[0059] In this embodiment, the stains are first soaked and decomposed by cleaning liquid or foam, and then the stubborn stains are further softened and sterilized by high temperature and high pressure steam. Finally, the treated stains are peeled off by a wet cleaning element to complete the cleaning. This solves the problem that a single cleaning method is not thorough and it is difficult to remove stubborn stains, thus improving cleaning efficiency and cleaning effect.

[0060] In some embodiments, such as Figure 2 As shown, the cleaning strategy includes: S201, Control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area.

[0061] Specifically, cleaning solutions or foams can soak, encapsulate, or chemically break down stains in the target area, reducing the adhesion between the stains and the surface, making subsequent cleaning steps easier and improving cleaning effectiveness. Depending on the type of stain, cleaning solutions, foams, or a combination of both can be flexibly selected to suit different cleaning scenarios.

[0062] S202, Control the wet cleaning element to mop the target area.

[0063] Specifically, after the cleaning solution or foam has soaked and broken down the stains, the target area is mopped for the first time. The target area is physically wiped and mopped using a wet cleaning element to initially remove the softened and loose surface stains, reducing the workload of subsequent steps and preventing stains from repeatedly adhering to the surface of the target area.

[0064] S203, Control the steam cleaning unit to output steam to the target area.

[0065] Specifically, after the first mopping of the target area, the steam cleaning unit continuously outputs high-temperature, high-pressure steam to the target area to further treat the stains.

[0066] Since the decomposed stains in the target area have been removed, the high-temperature, high-pressure steam softens the stains still adhering to the surface of the target area, enhancing the stain-removing activity of the cleaning liquid or foam and improving cleaning efficiency. It also has the effects of high temperature, mite removal, and odor elimination. The steam can further moisten the stains in the target area, reducing frictional resistance during subsequent mopping and improving cleaning results.

[0067] S204. Control the wet cleaning element to mop and wash the target area.

[0068] Specifically, after the steam output to the target area is processed, the stains in the target area have been decomposed and softened. The target area is then physically wiped and mopped by wet cleaning elements, and the stains in the target area are removed by friction.

[0069] In some embodiments, when a user discovers stubborn stains in certain areas, or when stains are automatically identified by the cleaning equipment, the location of the stubborn stains needs to be determined first.

[0070] To solve the above problems, before controlling the cleaning fluid unit to output cleaning fluid to the target area and / or controlling the foam cleaning unit to output foam to the target area, such as... Figure 3 As shown, the cleaning strategy also includes: S301. Obtain the location coordinates of the target area.

[0071] Specifically, the target area is the area with concentrated stains or the area requiring focused cleaning, as specified by the user or identified by the cleaning equipment, such as a heavily soiled area in the kitchen or an area on the floor with stubborn stains. The location coordinates are the coordinates of the target area within the coordinate system constructed by the cleaning equipment based on the working environment.

[0072] S302. Proceed to the target area based on its location coordinates.

[0073] Specifically, path planning is performed based on the location coordinates of the target area to calculate the optimal, obstacle-free route, thereby controlling the cleaning equipment to move to the target area so that subsequent steps can remove stains within the target area.

[0074] In some embodiments, for some stains containing adhesives, such as glue stains, self-adhesive labels, tape marks, etc., the adhesion is extremely strong and tough. It is difficult to penetrate into the stain using cleaning liquid or foam alone. Using steam alone can only soften the stain, but the adhesive will still stick to the surface and is difficult to remove completely.

[0075] To solve the above problems, such as Figure 4 As shown, the cleaning strategy in this embodiment includes: S401, Control the steam cleaning unit to output steam to the target area.

[0076] Specifically, the steam cleaning unit continuously outputs high-temperature and high-pressure steam to the target area to treat the stains. This causes the adhesive stains to melt and soften, breaking the adhesion between the adhesive and the surface of the target area, thus creating conditions for the subsequent penetration of cleaning liquid or foam.

[0077] S402, Control the cleaning fluid cleaning unit to output cleaning fluid to the target area and / or control the foam cleaning unit to output foam to the target area.

[0078] Specifically, after the stains in the target area are softened by steam, cleaning solutions or foams are used to further wet, coat, or chemically decompose adhesive stains in the target area. This reduces the adhesion between the stains and the surface of the target area, prevents the stains from re-adhering and hardening, and improves the cleaning effect. Depending on the type of stain, cleaning solutions, foams, or a combination of both can be flexibly selected to adapt to different cleaning scenarios.

[0079] S403, controls the wet cleaning element to mop and wash the target area.

[0080] Specifically, after the steam output to the target area is processed, the stains in the target area have been decomposed and softened. The target area is then physically wiped and mopped by wet cleaning elements, and the stains in the target area are removed by friction.

[0081] In some embodiments, the cleaning device further includes a stain recognition unit, which is used to identify stains within a target area to determine whether stains exist within the target area. The stain recognition unit can be a vision sensor, which uses a built-in image recognition algorithm to identify the image coordinates of the stain in the image, and converts the image coordinates into three-dimensional coordinates of the cleaning device according to calibration parameters obtained in advance by the vision sensor, thereby determining whether stains exist within the target area and the location of the stains.

[0082] Cleaning equipment can directly identify the target area to determine whether there are stains in the target area, or it can identify the target area after the cleaning steps are performed to determine the cleaning results of the cleaning steps that have been performed.

[0083] like Figure 5 As shown, the cleaning strategy in this embodiment includes: S501, Control the stain recognition unit to recognize stains in the target area and determine the recognition result of the target area.

[0084] Specifically, the stain recognition unit acquires an image of the target area, determines whether there is a stain in the image, and determines the recognition result of the target area, which includes whether there is a stain or not.

[0085] The stain recognition unit identifies stains within the target area, accurately determining the location that needs cleaning and providing a basis for subsequent steam output.

[0086] S502. If the identification result indicates the presence of stains, control the steam cleaning unit to output steam to the target area.

[0087] Specifically, when the identification result indicates the presence of stains, the steam cleaning unit is activated to output steam to the location of the stains in the target area, softening the stains at high temperature and improving the cleaning effect.

[0088] In some embodiments, the wet cleaning element is raised while the steam cleaning unit is controlling the output of steam to the target area.

[0089] Specifically, during the process of the steam cleaning unit outputting steam to the target area, the wet cleaning element is driven to rise upward through the mechanical lifting mechanism such as the built-in lifting motor and linkage, so that it is completely separated from the surface to be cleaned in the target area, leaving an unobstructed working space between the steam and the surface to be cleaned.

[0090] Because high-temperature steam needs to directly contact the surface of the stain to penetrate and soften it, if the wet cleaning element is always flat against the ground, it can easily block the steam jet path and absorb the heat or moisture from the steam. By raising the wet cleaning element, space can be created for the steam to work, allowing it to directly contact the stain and fully utilize its high-temperature softening and penetrating properties to improve cleaning effectiveness.

[0091] In some embodiments, the method further includes the following steps prior to the step of controlling the steam cleaning unit to output steam to the target area: Initiate steam preparation, prepare steam within the preset steam preparation time, and perform edge-by-edge analysis on the target area to determine the steam output parameters.

[0092] Specifically, steam preparation is the process of heating and vaporizing water inside the steam cleaning unit to obtain steam. Steam preparation needs to be carried out within a certain time frame, which can be set according to parameters such as the heating power of the cleaning equipment, the water tank capacity, and the temperature and pressure of the steam.

[0093] During the steam preparation time, while waiting for the steam to be generated, the cleaning equipment performs edge-by-edge cleaning of the target area, detecting the boundaries, material, and location of stains to determine the steam output parameters. These parameters include steam temperature, steam pressure, injection volume, and injection duration. By controlling these parameters, the cleaning equipment achieves the effect of softening stains with steam and protecting the surface of the target area.

[0094] By determining the steam output parameters while generating steam, the operating efficiency of the cleaning equipment can be optimized, thereby improving the cleaning effect.

[0095] In some embodiments, after the step of controlling the steam cleaning unit to output steam to the target area, at least one of the following cleaning steps is performed after a preset first reaction time interval: controlling the cleaning liquid cleaning unit to output cleaning liquid to the target area; controlling the foam cleaning unit to output foam to the target area; controlling the wet cleaning element to mop the target area.

[0096] Specifically, the first reaction time is the duration set according to user needs. It is the interval between the end of steam output and the start of subsequent cleaning. The first reaction time can be determined according to the type of stain or the surface material of the target area, so that the steam has enough time to soften the stain.

[0097] After the initial reaction time, subsequent cleaning steps can be initiated according to the cleaning strategy. For example, for stubborn adhesive stains, the softened adhesive stains can be broken down by using cleaning liquid or foam, or for light stains or floating oil, the stains can be removed by physical friction through the wet cleaning unit.

[0098] In some embodiments, like Figure 6 As shown, the cleaning strategy also includes: S601, Control the cleaning fluid cleaning unit to output cleaning fluid to the target area and / or control the foam cleaning unit to output foam to the target area.

[0099] Specifically, cleaning solutions or foams can soak, encapsulate, or chemically break down stains in the target area, reducing the adhesion between the stains and the surface, making subsequent cleaning steps easier and improving cleaning effectiveness. Depending on the type of stain, cleaning solutions, foams, or a combination of both can be flexibly selected to suit different cleaning scenarios.

[0100] S602. After a preset second reaction time, control the wet cleaning element to mop the target area.

[0101] Specifically, after a preset second reaction time, the mopping parameters of the wet cleaning element are adjusted, and the wet cleaning element is controlled to mop the target area according to the mopping parameters. The mopping parameters include at least one of the following: the amount of cleaning solution sprayed during mopping and the amount of water on the mop cloth. The second reaction time is used to ensure that the cleaning solution or foam fully penetrates and breaks down the stains, preventing the wet cleaning unit from intervening too early and starting mopping before the cleaning solution or foam has fully reacted, thus improving cleaning effectiveness. Furthermore, since the cleaning solution or foam has already penetrated the stains, the target area has a higher humidity level, so the amount of cleaning solution sprayed or the amount of water on the cloth should be reduced during mopping to avoid excessive humidity in the target area during mopping.

[0102] In some embodiments, the control method further includes: Obtain the material of the target area and determine the steam output parameters based on the material.

[0103] Specifically, the material of the target area can be identified through commands from the user terminal or through images acquired by the stain recognition unit. Steam output parameters include steam temperature, steam pressure, injection volume, and injection duration.

[0104] In some examples, when the target area is made of ceramic tile, the tile has high heat resistance and the gaps between the tiles are difficult to clean. Therefore, the steam temperature, steam pressure, spray volume and spray duration can be increased, for example, the maximum steam temperature is 110°C.

[0105] When the target area is made of flooring or glass, flooring has low heat resistance and is prone to corrosion under high humidity. Glass is also prone to cracking at high temperatures. Therefore, the steam temperature, steam pressure, spray volume, and spray duration can be reduced, for example, by limiting the steam temperature to 80°C.

[0106] When the target area is made of carpet or cement, carpet contains a lot of fibers, and excessive pressure or temperature can easily cause the fibers to deform or be damaged, affecting the appearance or lifespan of the carpet. Cement floors have a porous structure, and steam can easily cause the cement floor to become powdery. Therefore, the amount of steam injected is limited to 0, and steam is disabled.

[0107] In some embodiments, prior to the step of cleaning the target area according to a cleaning strategy, the method further includes: Receive communication information from the mobile terminal.

[0108] Specifically, the mobile terminal is a handheld interactive device, such as a mobile phone or tablet, with functions such as taking photos, interacting, and wireless communication. The mobile terminal and the cleaning equipment can communicate via wireless networks or Bluetooth. The user can send communication information to the cleaning equipment through the mobile terminal. This communication information includes at least one of a cleaning strategy and a target area. The communication information may contain only the cleaning strategy, only the target area, or a combination of both. For example, the user selects the target area to be cleaned or chooses a cleaning strategy to execute on the mobile terminal and sends this information to the cleaning equipment. After receiving the communication information, the cleaning equipment performs cleaning according to the target area or cleaning strategy specified in the communication information.

[0109] In some embodiments, the communication information includes a target area, which is determined based on an image uploaded to the mobile terminal. For example, a user takes an image containing stains using the mobile terminal, determines the location of the stains based on the image, divides the location of the stains into zones to obtain the target area, generates communication information, and sends the communication information to the cleaning device. The cleaning device then moves to the corresponding location to perform cleaning based on the target area in the communication information.

[0110] In some embodiments, the cleaning equipment is equipped with a liveness sensor, which is used to detect whether there are living organisms such as humans or pets within the working range of the cleaning equipment, and outputs a corresponding status signal.

[0111] The steps for supplying steam to the target area include: During the process of controlling the steam cleaning unit to output steam to the target area, the presence of living organisms around the cleaning equipment is detected by a living organism sensor. If the presence of living organisms is indicated by the living organism sensor, the steam cleaning unit is controlled to stop outputting steam to the target area.

[0112] Specifically, the liveness sensor can be an infrared sensor, microwave radar, vision sensor, ultrasonic sensor, etc. For example, it can use a monocular or binocular camera to monitor the images around the cleaning equipment in real time. When a human or pet is detected in the image, it generates liveness status information. If the liveness status information indicates the presence of a live animal, it controls the steam cleaning unit to stop outputting steam to the target area.

[0113] In some embodiments, the cleaning equipment is provided with a prompting device for outputting prompting information to the surroundings to indicate the current cleaning step, so that people or pets in the vicinity can notice and stay away.

[0114] While outputting steam to the target area, a first prompt message is output through a prompting device, wherein the first prompt message indicates that the steam cleaning unit is outputting steam to the target area.

[0115] Specifically, when steam is being output to the target area, the high temperature can easily cause burns to humans or pets who get close. Therefore, while steam is being output to the target area, a warning message is displayed via a notification device. This message can be displayed through sound, light, or voice announcements. For example, a flashing red warning light, a high-frequency buzzer, or a voice announcement stating "Steam cleaning in progress, please do not approach" can clearly inform nearby humans or pets that steam is being output, prompting them to stay away.

[0116] While spraying cleaning fluid, dispensing foam, or mopping the target area, a second notification message is output through a notification device.

[0117] Specifically, while spraying cleaning fluid, outputting foam, or mopping the target area, a second warning message is output through a warning device. Because the cleaning steps of spraying cleaning fluid, outputting foam, or mopping the target area are relatively low-risk, the second warning message differs from the first warning message to emphasize the danger of outputting steam. The second warning message can be output through sound, light, or voice announcements. For example, it can be output through flashing green or blue warning lights, low-frequency beeping, or voice announcements such as "cleaning fluid spraying" or "mopping in progress," clearly informing people in the vicinity of the cleaning step being performed and enabling them to quickly identify the cleaning step being performed by the cleaning equipment.

[0118] In some embodiments, the cleaning equipment includes a temperature sensor for detecting the temperature of the cleaning equipment or the target area.

[0119] The steps for supplying steam to the target area include: While outputting steam to the target area, the temperature sensor monitors the temperature inside the cleaning equipment or the target area; if the temperature inside the cleaning equipment exceeds a preset first temperature threshold or the temperature of the target area exceeds a preset second temperature threshold, the steam cleaning unit is controlled to stop outputting steam to the target area.

[0120] Specifically, a temperature sensor can be installed inside the cleaning equipment to detect the internal temperature of the equipment during steam generation, such as on the piping in the steam cleaning unit. A first temperature threshold is the highest safe temperature that the internal components of the cleaning equipment can withstand; exceeding this threshold will cause the components to age or be damaged. When the internal temperature of the cleaning equipment exceeds the preset first temperature threshold, the steam cleaning unit is controlled to stop outputting steam to the target area, preventing the internal components of the cleaning equipment from aging or being damaged.

[0121] Temperature sensors can also be installed at the bottom of the cleaning equipment to detect the surface temperature of the target area. Different materials can withstand different maximum temperatures; for example, prolonged exposure to high-temperature steam can easily cause wooden floors to crack, warp, or fade. The second temperature threshold is the highest safe temperature the target area surface can withstand; exceeding this threshold can easily damage the target area. When the surface temperature of the target area exceeds the preset second temperature threshold, the steam cleaning unit stops outputting steam to the target area to prevent surface damage.

[0122] In some embodiments, the cleaning device includes a humidity sensor for detecting the humidity of the target area.

[0123] The steps for supplying steam to the target area include: While outputting steam to the target area, the control steam cleaning unit monitors the humidity of the target area through a humidity sensor. If the humidity exceeds a preset humidity threshold, the steam output to the target area is stopped.

[0124] Specifically, a humidity sensor can be installed at the front end of the cleaning equipment. While outputting steam to the target area, it simultaneously monitors the humidity of that area. Outputting steam causes significant condensation, which can lead to slippery surfaces, and make wooden floors and furniture susceptible to dampness and mold growth in high humidity environments. The humidity threshold is a preset value or an adaptively set upper limit based on the current scenario. Steam output to the target area stops when the humidity exceeds the preset threshold.

[0125] In some embodiments, the cleaning device includes a multicolor light detector for emitting detection light of various colors or wavelengths.

[0126] Control methods also include: The stains in the target area are identified by a multi-color light detector to determine the cleaning results of the target area.

[0127] Specifically, after the cleaning steps are completed, a multi-color light detector emits various colors or wavelengths of detection light, such as blue or green light, and infrared light, towards the target area. The light reflects off the cleaned surface of the target area, and the multi-color light detector receives the reflected light. The cleaning result of the target area is determined based on the parameters of the reflected light. If residual stains are present, they will absorb or deflect specific colors or wavelengths of light, causing a noticeable anomaly in the reflected light. The cleaning result includes the presence of stains and the absence of stains. In the case of stains, the cleaning strategy is repeated to clean the target area.

[0128] Secondly, embodiments of this application provide a cleaning device, which includes a steam cleaning unit, and at least one of a cleaning liquid cleaning unit and a foam cleaning unit; The cleaning equipment also includes a controller, which performs the following steps: Clean the target area according to the cleaning strategy; The cleaning strategy includes the step of controlling the steam cleaning unit to output steam to the target area, and at least one of the following cleaning steps: Control the cleaning fluid cleaning unit to output cleaning fluid to the target area; Control the foam cleaning unit to output foam to the target area.

[0129] Specifically, the cleaning strategy is a pre-set cleaning plan or a cleaning scheme generated based on the contamination status of the target area, which includes control rules for the start-up, shutdown, working sequence, and output of the steam cleaning unit, cleaning liquid cleaning unit, or foam cleaning unit.

[0130] The cleaning strategy can first control the steam cleaning unit to output steam to the target area, then control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area; alternatively, it can first control the cleaning liquid cleaning unit to output cleaning liquid to the target area and / or control the foam cleaning unit to output foam to the target area, then control the steam cleaning unit to output steam to the target area.

[0131] By combining steam with cleaning liquid and foam, it is suitable for various cleaning scenarios such as common dust, heavy stains, and stubborn stains, improving cleaning efficiency and cleaning effect.

[0132] In some embodiments, such as Figure 7 As shown, the cleaning equipment also includes a water tank 200, which is used to store clean water or cleaning solution.

[0133] The steam cleaning unit 100 includes a heating module 101, a fluid handling device 102, and a jet support 103.

[0134] The heating module 101 is connected to the water tank 200 through the first pipe 104; the fluid handling device 102 is connected to the heating module 101 through the second pipe 105; a steam channel is provided inside the jet support 103, and a nozzle 106 is provided on the jet support 103. The steam channel, the nozzle 106, and the fluid handling device 102 are connected; the jet support 103 is inside the cleaning equipment, and the output direction of the nozzle 106 is towards the wet cleaning element or the target area.

[0135] Specifically, clean water in water tank 200 enters heating module 101 through first pipe 104. Heating module 101 heats and vaporizes the clean water into steam. The steam enters fluid processing device 102 through second pipe 105 to achieve steam pressure stabilization. The steam enters jet support 103 through steam channel and is ejected from nozzle 106 on jet support 103. The output direction of nozzle 106 can be to spray steam onto the roller or mop of wet cleaning element for high-temperature sterilization of wet cleaning element, or it can be directly sprayed onto target area to soften stains at high temperature.

[0136] In some embodiments, the cleaning liquid cleaning unit and the foam cleaning unit can reuse the same structure as the steam cleaning unit 100. For example, if the heating module 101 is not activated, the clean water or cleaning liquid in the water tank 200 is directly sprayed out through the jet bracket 103 after passing through the heating module 101, thereby realizing the output of the cleaning liquid. A foam generator is provided in the jet bracket 103 to realize the output of foam.

[0137] In some embodiments, such as Figure 8 As shown, the cleaning equipment includes a multicolor light detector 300, which is located at the front end of the cleaning equipment. The multicolor light detector 300 is used to emit detection light of various colors or wavelengths, such as blue or green light, and infrared light, towards the target area. The light shines on the surface of the cleaned target area and is reflected. The multicolor light detector 300 receives the reflected light and determines the cleaning result of the target area based on the parameters of the reflected light. If residual stains are present, they will absorb or deflect light of a specific color or wavelength, making the reflected light have a more obvious anomaly.

[0138] Specifically, the multicolor light detector 300 includes an infrared emitter 301 and a colored light emitter 302. There are two infrared emitters 301, positioned on either side of the colored light emitter 302. The two infrared emitters 301 can simultaneously emit infrared light towards the target area. When the infrared light shines on a stain, it produces a different reflectivity and scattering characteristics compared to a clean surface, thus identifying the stain in the target area. The colored light emitter 302 emits colored visible light, such as blue or green light, accurately identifying stains by recognizing color or brightness differences in the target area.

[0139] In some embodiments, such as Figure 9 As shown, the cleaning equipment includes a notification device 400, which surrounds the outer periphery of the cleaning equipment. The notification device 400 is used to output notification information to the surrounding area to indicate the current cleaning step, making it easier for nearby humans or pets to notice and stay away.

[0140] In some embodiments, the indicator device 400 is a light strip that wraps around the outer periphery of the cleaning equipment and can display different colors of light. For example, while outputting steam to the target area, a red warning light flashes through the light strip; while spraying cleaning liquid, outputting foam, or mopping the target area, a green or blue warning light flashes through the light strip.

[0141] This application utilizes a cleaning strategy that flexibly combines steam-output cleaning methods with various cleaning steps to achieve synergistic effects, improve cleaning efficiency and effectiveness, and remove stubborn stains.
