Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device and its control method and cleaning system. Background Technology

[0002] With the rapid development of smart home technology, floor cleaning equipment has been widely used in homes, offices and other settings, becoming an important tool in people's daily lives.

[0003] In related technologies, some cleaning devices spray water or cleaning solution onto the ground in front of them during the mopping process. When the cleaning device reaches this position, the mop makes contact with the ground and drags, using friction to peel off the dirt from the ground.

[0004] However, the cleaning equipment mentioned above often fails to achieve the expected cleaning effect when cleaning heavily soiled areas, resulting in residual stains in localized areas and poor cleaning performance, which cannot meet user needs. Summary of the Invention

[0005] This application provides a cleaning device and its control method, as well as a cleaning system, to solve the technical problem that in the related art, the cleaning effect of the cleaning device is often difficult to achieve as expected when cleaning areas with heavy dirt, resulting in residual stains in local areas, poor cleaning effect, and failure to meet user needs.

[0006] In a first aspect, embodiments of this application provide a cleaning device, including:

[0007] The machine body can move on the surface to be cleaned;

[0008] A cleaning component is provided on the machine body, and the cleaning component is used to clean the surface to be cleaned;

[0009] The clean water tank is located on the machine body;

[0010] The water spray device has at least a first water path and a second water path. One end of the first water path and one end of the second water path are both connected to the clean water tank. The other end of the first water path is formed on the outside of the machine body and faces the surface to be cleaned. The other end of the second water path is connected to the cleaning component. The cleaning device has a spray mode.

[0011] When the cleaning equipment is in the spray mode, the water spraying device is configured to transfer the liquid in the clean water tank to the first water path to spray the liquid into a water mist onto the surface to be cleaned.

[0012] The cleaning equipment provided in this application embodiment can spray water onto the roller while simultaneously spraying water toward the surface to be cleaned during cleaning operations.

[0013] Compared to related technologies that only spray water towards the surface to be cleaned or the roller, the cleaning equipment provided in this application has a higher water output, which can increase the wetness of the stains and thus improve the cleaning effect of the cleaning equipment.

[0014] Furthermore, compared to any solution in related technologies, the embodiments of this application add a new water channel based on the existing water channel. Therefore, the embodiments of this application can add a water channel that can bypass a solid structure to existing cleaning equipment without affecting the size, shape, etc. of the cleaning equipment itself, thus eliminating the need to re-manufacture the cleaning equipment and reducing manufacturing costs.

[0015] By spraying water mist onto the surface to be cleaned, compared to the method of spraying water jets in related technologies, water mist has higher permeability, and stains are penetrated at a faster rate. The cleaning components can quickly remove stains under the same pressure and speed, thereby improving the cleaning effect. At the same time, because the water droplets are small, the water mist is less likely to form watermarks on the surface to be cleaned, eliminating the need for users to clean watermarks again, reducing the number of times the cleaning equipment needs to be cleaned, and improving the user experience.

[0016] As an optional implementation, the first water passage has a first nozzle formed on the outside of the fuselage, the fuselage can move along a preset travel direction, and the first nozzle is located on the rear side of the fuselage in the preset travel direction.

[0017] With the above configuration, the cleaning device can move backward and clean the surface to be cleaned again. Compared to related technologies that repeatedly clean the entire surface multiple times, the cleaning device completes multiple cleaning cycles in a shorter distance. Furthermore, the cleaning device provided in this application embodiment can focus on cleaning stubborn stains.

[0018] As an optional implementation, the water spraying device includes a drive assembly and a nozzle located in the first water path, the nozzle having the first spray nozzle;

[0019] When the cleaning device is in the spray mode, the drive assembly is used to transfer the liquid in the clean water tank to the nozzle and spray water mist through the nozzle.

[0020] The cleaning device provided in this application atomizes liquid through a nozzle and sprays it onto the target dirty area through a first nozzle located at the rear of the main unit. The water mist can quickly wet and penetrate the stain layer, softening the stain and reducing its adhesion. Combined with the main unit's backward and reciprocating movement, the cleaning component (such as a roller) repeatedly passes over the target dirty area, achieving high-frequency wiping. Due to the large coverage area of ​​the water mist and its rapid penetration rate with the stain, it has a higher water output compared to cleaning devices in related technologies, which can fully wet the stain and improve the cleaning effect.

[0021] As an optional implementation, the water spraying device further includes a water spray plate located in the second water path, the water spray plate having a second nozzle facing the cleaning component;

[0022] A control component is connected between the first waterway and the second waterway, and the control component is connected to the drive component.

[0023] The control component is used to selectively connect the liquid transmitted by the drive component to at least one of the nozzle and the spray plate to spray the liquid onto the surface to be cleaned and / or the cleaning component.

[0024] With the above-described configuration, this embodiment of the application, without adding a water pump, can selectively supply liquid to the surface to be cleaned (via nozzles) and the cleaning components (via spray plates) using only one set of drive and control components. This configuration solves the technical problems of traditional cleaning equipment in related technologies, which suffers from poor cleaning effect and water waste due to the single function of the water circuit, inability to simultaneously address the pretreatment of the surface to be cleaned and the maintenance of humidity on the cleaning components. It features high functional integration, minimal size variation, and high energy efficiency.

[0025] As an optional implementation, when the cleaning device is in the spray mode,

[0026] The control component controls the first water path and the second water path to be connected to the drive component. The drive component is used to transfer the liquid in the clean water tank to the first nozzle and the second nozzle, and the time when the liquid is sprayed from the second nozzle is later than the time when the liquid is sprayed from the first nozzle.

[0027] or,

[0028] The control component controls the first water path to be connected to the drive component and the second water path to be disconnected from the drive component. The drive component is used to transfer the liquid in the clean water tank to the first nozzle.

[0029] With the above configuration, when both the first and second water channels are connected, the cleaning equipment can increase the humidity of the surface to be cleaned while maintaining a high humidity of the parts being cleaned. The nozzles and spray plates can be used together to deal with stubborn stains that are difficult to clean. When only the first water channel is open, all the driving energy of the drive assembly is supplied to the first water channel, ensuring that the first nozzle obtains a high flow rate and a better atomized particle size, which is conducive to forming a uniform water mist with a longer suspension time.

[0030] As an optional implementation, the control component includes a three-way valve, a first valve, and a second valve, and the drive component includes a check valve, an air pump, and a third valve, wherein the air pump is connected to the clean water tank through the third valve and the check valve;

[0031] The first end of the three-way connector is connected to the clean water tank, the nozzle is connected to the second end of the three-way connector through the first valve, and the spray plate is connected to the third end of the three-way connector through the second valve;

[0032] The air pump is used to provide gas to transfer the liquid in the water tank to the nozzle and / or spray plate.

[0033] The technical solution provided in this application embodiment, after identifying the target dirty area, the cleaning device first moves forward past the area and then retreats to the corresponding position. At this time, the air pump starts and injects compressed gas into the clean water tank through the third valve and the one-way valve, creating positive pressure inside the tank; the pressure drives the clean water to be diverted through the three-way fitting and guided to the nozzle through the first valve, forming a water mist covering the target dirty area on the rear side of the main unit; after the water mist wets the target dirty area, the cleaning component repeatedly drags the target dirty area as the main unit moves backward, completing the enhanced cleaning of the target dirty area.

[0034] During the above process, because the air pump provides a controllable positive pressure rather than a continuous water flow, the nozzle's start-stop response is relatively fast, and the possibility of dripping is small. The one-way valve can prevent gas backflow, so filling and replenishing the clean water tank will not affect the safety of the air circuit.

[0035] As an optional implementation, it also includes a scraper and a wastewater tank, wherein the scraper is located on the periphery of the cleaning component and is used to scrape and wash the cleaning component; the wastewater tank is used to receive wastewater after being scraped and washed by the scraper.

[0036] The water spraying device also includes a spraying element that is directed toward the sewage tank and is used to spray liquid to clean the sewage tank.

[0037] The nozzle, the water spray plate, and the spray element are all connected to the control component;

[0038] The control component is used to selectively connect the liquid transmitted by the drive component to at least one of the nozzle, the spray plate, and the spray element, so as to spray the liquid onto at least one of the surface to be cleaned, the cleaning element, and the wastewater tank.

[0039] With the above setup, the scraper continuously scrubs to ensure that wastewater flows directionally into the wastewater tank, preventing backflow onto the surface to be cleaned and affecting the cleaning effect. The spray unit automatically cleans the wastewater tank, eliminating the need for manual cleaning by the user and improving the user experience. Furthermore, by sharing the same control and drive components with the nozzles, spray plates, and spray unit, wastewater tank cleaning can be performed simultaneously with or independently of functions such as spraying towards the surface to be cleaned and self-cleaning of the cleaning unit, improving water resource utilization. This solves the problem of wastewater accumulating in the scraper and wastewater tank, causing secondary pollution or blockage, reduces odor, enhances self-cleaning capabilities, and improves the user experience.

[0040] As an optional implementation, the control assembly includes a four-way valve, a fourth valve, a fifth valve, and a sixth valve; the drive assembly includes a peristaltic pump electrically connected to the fourth valve, the fifth valve, and the sixth valve.

[0041] The peristaltic pump is connected to the clean water tank and the first end of the four-way connector;

[0042] The fourth valve is connected to the nozzle and the second end of the four-way connector;

[0043] The fifth valve is connected to the third end of the spray plate and the four-way connector;

[0044] The sixth valve is connected to the fourth end of the injection component and the four-way component;

[0045] The peristaltic pump is used to transfer liquid in the clean water tank to at least one of the nozzle, the spray plate, and the spray element.

[0046] With the above configuration, this embodiment of the application, while maintaining the layout of the cleaning equipment, uses a peristaltic pump instead of an air pump as the driving core, combined with a four-way valve and three sets of independent solenoid valves to open and close the water circuit. The peristaltic pump has characteristics such as leak-free operation, low noise, and bidirectional fluid control, and can simultaneously provide pressurized water spray and absorb wastewater, thereby improving the intelligence level of the cleaning equipment and enhancing the user experience.

[0047] Secondly, this application embodiment also provides a cleaning system, including a base station and the cleaning equipment, wherein the base station includes a base station body and a water storage tank, the water storage tank is located on the base station body, and the water storage tank is connected to the clean water tank;

[0048] When the water spray device of the cleaning equipment includes a four-way valve, a fourth valve, a fifth valve, a sixth valve, and a peristaltic pump,

[0049] The cleaning equipment also includes a two-position three-way valve, which is connected to the water storage tank, the clean water tank, and the peristaltic pump respectively; the two-position three-way valve has a first state in which the peristaltic pump is connected to both the water storage tank and the clean water tank, and a second state in which the peristaltic pump is connected to both the clean water tank and the four-way connector.

[0050] When the two-position three-way valve is in the first state, the peristaltic pump is used to draw liquid from the water storage tank and deliver it to the clean water tank.

[0051] With the above setup, when the cleaning equipment connects to the base station, a two-position three-way valve is controlled to connect to the water storage tank. The peristaltic pump is then activated, allowing liquid in the storage tank to be drawn and transported to the clean water tank. This solves the problem of frequent manual water refilling caused by the limited capacity of the clean water tank.

[0052] Furthermore, peristaltic pumps can also be used to achieve spraying, water spraying, and self-cleaning functions in cleaning equipment, eliminating the need to add a separate water injection unit to the base station or cleaning equipment. This reduces the complexity of the cleaning system and thus lowers manufacturing costs.

[0053] Thirdly, this application also provides a control method applied to the cleaning equipment, the control method comprising:

[0054] Control the cleaning equipment to clean the surface to be cleaned;

[0055] Control the cleaning equipment to enter spray mode and spray water mist onto the surface to be cleaned behind the machine;

[0056] The body of the cleaning device is controlled to move backward along a preset direction to the surface to be cleaned, and then moves back and forth so that the cleaning components of the cleaning device repeatedly clean the surface to be cleaned.

[0057] Through the aforementioned control method, the cleaning equipment, by reciprocating backward, can extend the residence time of the cleaning components in heavily soiled areas. Furthermore, the repeated forward and reverse friction between the cleaning components and the stains improves the efficiency of stain removal. This control method solves the technical problem of poor cleaning effect for heavily soiled stains in related technologies without adding hardware.

[0058] As an optional implementation, the cleaning device further includes an identification element located on the main unit; the identification element is disposed facing the surface to be cleaned and is used to identify a target dirty area on the surface to be cleaned; before controlling the cleaning device to enter the spray mode, it further includes:

[0059] Control the operation of the identification device;

[0060] The identification device determines whether the cleaning equipment has entered spray mode.

[0061] If the identification device detects the target dirty area...

[0062] Control the water spray device of the cleaning equipment to spray towards the target dirty area;

[0063] The machine body is controlled to move backward along a preset travel direction to the target dirty area and move back and forth, so that the cleaning components of the cleaning equipment repeatedly clean the target dirty area.

[0064] With the above settings, the identification component maintains cleaning of the target dirty area as the cleaning device reciprocates to clean the surface until the target dirty area can no longer be identified by the identification component. At this point, the cleaning device exits the spray mode and continues cleaning the surface. The identification component allows the cleaning device to adaptively clean according to the actual condition of the surface, providing high versatility and improving the user experience.

[0082] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0083] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0084] In a first aspect, embodiments of this application provide a cleaning system (not shown in the figures), including cleaning equipment and a base station. The cleaning equipment can be placed on the base station.

[0085] Cleaning equipment can include floor scrubbers, vacuum cleaners, robotic vacuum cleaners, robotic mopping robots, and robotic vacuum and mop combos. The cleaning equipment in this embodiment is a robot with mopping functionality, such as a robotic mopping robot or a robotic vacuum and mop combo.

[0086] Secondly, embodiments of this application also provide a base station. The base station includes a base station body (not shown in the figure), which is used to interface with cleaning equipment.

[0087] After cleaning the surface, the cleaning equipment can be placed on the base station for positioning, charging, self-cleaning, drying, or drainage. The base station has designated placement areas for the cleaning equipment. It also has a charging port for charging. A drain pipe can be installed on the base station to drain the wastewater from the cleaning equipment's tank. A drying device can be installed on the base station to dry the cleaned equipment. Finally, a water sprayer is installed on the base station to spray water onto the cleaning equipment for self-cleaning.

[0088] It should be noted that the base station itself generally needs to be fixed to the surface to be cleaned in order to support the operation of the cleaning equipment.

[0089] In some embodiments, the base station body is also provided with a water storage tank for storing liquids. When the cleaning equipment is connected to the base station body, the cleaning equipment can communicate with the water storage tank, which provides clean water to the cleaning equipment.

[0090] Reference Figure 1 Thirdly, this application embodiment also provides a cleaning device 20, which includes a body 100 and a cleaning component 200.

[0091] It is understood that the cleaning unit 200 is suitable for performing cleaning actions on the surface A to be cleaned to achieve a cleaning effect. The surface A to be cleaned can be a surface of varying roughness, a wall surface, or a carpet, blanket, or object of varying lengths or types. This application does not specifically limit the type of surface A to be cleaned. The cleaning action can be vacuuming, mopping, or both simultaneously, to ensure the cleaning efficiency of the cleaning device 20.

[0092] The cleaning component 200 is mounted on the machine body 100. It should be noted that the type of cleaning component 200 can be varied; cleaning components include, but are not limited to, rollers, brushes, belts, mops, etc., all of which can clean the surface A to be cleaned. This application embodiment does not limit the specific type of cleaning component; the following example uses a roller as an example.

[0093] In some embodiments, the roller can rotate relative to the machine body 100, allowing the cleaning device 20 to clean the surface A to be cleaned while traveling in a preset direction X. (Refer to...) Figure 1 The preset travel direction X refers to the travel direction of the cleaning equipment 20.

[0094] In some embodiments, the cleaning device 20 further includes a clean water tank 300 located on the body 100. The clean water tank 300 is used to store liquid. When the cleaning device 20 is connected to the base station 10 body, the liquid storage tank on the base station 10 body can communicate with the clean water tank 300 to transfer liquid to the clean water tank 300.

[0095] It is understood that the liquid in the clean water tank 300 may include, but is not limited to, clean water, cleaning solution, or a mixture of clean water and cleaning solution.

[0096] In related technologies, during the cleaning process, the front of the cleaning equipment 20 is usually equipped with a water spray nozzle, which is connected to a clean water tank 300. The water spray nozzle can spray the liquid in the clean water tank 300 onto the ground in front of the cleaning equipment 20, so that the cleaning equipment 20 cleans the surface A to be cleaned while moving forward.

[0097] However, during the cleaning operation, the water jets sprayed by the above-mentioned cleaning equipment 20 are relatively concentrated, and can only partially wet dried and adhered stains, resulting in uneven wetting and poor cleaning effect.

[0098] In some other cleaning devices 20, the cleaning device 20 is also equipped with a water spray nozzle, but it is not located on the front of the cleaning device 20, but on the position of the roller, so as to spray water onto the roller, so that the roller self-cleans while cleaning the surface A to be cleaned.

[0099] However, the cleaning device 20 described above relies solely on the water-laden roller to wipe surfaces A that are difficult to clean in a single pass, such as those with oil stains. Although the roller can maintain a relatively uniform level of moisture when in contact with the stains after spraying water, the amount of water carried by the roller itself is limited, resulting in a low degree of moisture on the stains. Therefore, the cleaning effect of the cleaning device 20 is poor.

[0100] Reference Figure 2 In view of this, this application provides a cleaning device 20 with a water spraying device 400.

[0101] Reference Figure 2 In some embodiments, the cleaning device 20 has at least a first water channel 21 and a second water channel 22. One end of the first water channel 21 and one end of the second water channel 22 are both connected to a clean water tank 300. The other end of the first water channel 21 is formed on the outside of the body 100 and faces the surface A to be cleaned. The other end of the second water channel 22 is connected to a cleaning component 200. That is, the first water channel 21 can lead to the surface A to be cleaned, and the second water channel 22 can lead to the cleaning component 200 (i.e., the roller).

[0102] It is understandable that both the first water channel 21 and the second water channel 22 can be connected to the clean water tank 300. Therefore, the liquid in the clean water tank 300 can flow to the first water channel 21, the second water channel 22, or both simultaneously. Of course, the first water channel 21 and the second water channel 22 can be interconnected.

[0103] Furthermore, the order in which the first water path 21 and the second water path 22 are connected can also be different. For example, the first water path 21 and the second water path 22 can be connected simultaneously, meaning the water spraying device 400 sprays water onto the surface to be cleaned A and the cleaning component 200 at the same time. Another example is that the first water path 21 can be connected first, and then the second water path 22 can be connected, meaning the water spraying device 400 sprays water onto the surface to be cleaned A first, and then sprays water onto the cleaning component 200. Yet another example is that the second water path 22 can be connected first, and then the first water path 21 can be connected, meaning the water spraying device 400 sprays water onto the cleaning component 200 first, and then sprays water onto the surface to be cleaned A. This application does not limit the embodiments in this regard, nor is it limited to the above examples.

[0104] It should be noted that the other end of the first water passage 21 is formed on the outside of the fuselage 100, which means that the outlet of the first water passage 21 is exposed on the outer contour of the fuselage 100 shell.

[0105] The orientation towards the surface A to be cleaned can refer to the angle between the opening of the outlet and the extending direction of the surface A to be cleaned. For example, this angle can be any angle between 0° and 180°, including but not limited to 1°, 10°, 30°, 90°, 179°, and 180°. This application does not limit the orientation angle of the opening, nor is it limited to the above example.

[0106] In some embodiments, since the body 100 is above the surface A to be cleaned, in order to ensure that the liquid output from the first water channel 21 can be sprayed toward the surface A to be cleaned, the aforementioned included angle range can be any angle between 5° and 90°, and can be selected according to the actual situation.

[0107] With the above configuration, the water spraying device 400 has a first water path 21 that sprays water toward the surface A to be cleaned and a second water path 22 that sprays water toward the cleaning component 200 (i.e., the roller). The cleaning equipment 20 with this water spraying device 400 can spray water onto the roller at the same time as spraying water toward the ground during cleaning operations.

[0108] Compared to related technologies that only spray water towards the surface to be cleaned (A) or a roller, the cleaning device 20 provided in this application embodiment has a higher water output, which can increase the wetness of the stains and thus improve the cleaning effect of the cleaning device 20.

[0109] Furthermore, compared to any solution in the related technologies, the embodiments of this application add a new water channel based on the existing water channel. Therefore, the embodiments of this application can add a water channel that can bypass the solid structure to the existing cleaning equipment 20 without affecting the size, shape, etc. of the cleaning equipment 20 itself, so there is no need to redesign the cleaning equipment 20, which can reduce the manufacturing cost.

[0110] In some embodiments, the cleaning device 20 has a spray mode. It is understood that the spray mode can be a state of the cleaning device 20 during a cleaning operation.

[0111] When the cleaning device 20 is in spray mode, the water spraying device 400 is configured to transfer the liquid in the clean water tank 300 to the first water path 21 to spray the liquid to form a water mist onto the surface A to be cleaned.

[0112] Understandably, water mist, compared to a water column, diffuses and thus covers a larger area. Additionally, when spraying onto the same surface A to be cleaned, water mist requires less water than a water column. Furthermore, compared to a water column, water mist is absorbed by the surface A or stains more quickly, leaving less watermarks.

[0113] By spraying water mist onto the surface A to be cleaned, compared to the method of spraying water jets in related technologies, water mist has higher permeability, and stains are penetrated at a faster rate. The cleaning component 200 can quickly remove stains under the same pressure and speed, thus improving the cleaning effect. At the same time, because the water droplets are small, the water mist is less likely to form watermarks on the surface A, eliminating the need for users to clean watermarks again, reducing the number of times the cleaning device 20 needs to clean and improving the user experience.

[0114] Finally, the cleaning device 20 provided in this application embodiment, by being equipped with a water spraying device 400 that can spray water mist toward the surface to be cleaned A and spray water toward the cleaning component 200, has a high water output, which can increase the wetness of the stains and thus improve the cleaning effect of the cleaning device 20. In addition, when encountering stubborn stains, the cleaning device provided in this application embodiment can first soften the stains with a spray; then clean them by stacking the moistened cleaning component 200 (such as a roller), which greatly improves the cleaning effect.

[0115] In addition, the embodiments of this application can add water channels that can be routed around the solid structure to the existing cleaning equipment 20 without affecting the size, shape, etc. of the cleaning equipment 20 itself. Therefore, there is no need to redesign the cleaning equipment 20, which can reduce the manufacturing cost.

[0116] As an alternative implementation, the first water passage 21 has a first nozzle 211 formed on the outside of the fuselage 100.

[0117] It is understood that the shape of the first nozzle 211 can be varied, such as a round hole, a slit, a multi-hole array, or a fan-shaped nozzle; the size of the first nozzle 211 can also be varied, with its inner diameter being 0.1mm, 0.3mm, 0.5mm, 1mm, 10mm, and 100mm, etc. This application does not specifically limit the shape and size of the first nozzle 211, and the actual situation shall prevail.

[0118] According to the foregoing, the cleaning equipment 20 can move along the preset travel direction X, that is, the body 100 can move along the preset travel direction X.

[0119] Reference Figure 1 In some embodiments, the first nozzle 211 is located on the rear side of the body 100 in the preset travel direction X. This arrangement ensures that the spray acts on the surface A to be cleaned after the body 100 has traveled, i.e., on the surface A to be cleaned after being cleaned by the cleaning component 200. In this way, the cleaning device 20 can move backward and clean the surface A to be cleaned again. Compared to related technologies that repeatedly clean the entire surface A to be cleaned multiple times, the cleaning device 20 completes multiple cleanings in a shorter distance. Furthermore, the cleaning device 20 provided in this application embodiment can focus on cleaning stubborn stains.

[0120] Reference Figure 3 Fourthly, embodiments of this application also provide a control method applied to a cleaning device 20. The control method includes:

[0121] S100, Control the cleaning equipment to clean the surface to be cleaned.

[0122] That is, the cleaning device 20 performs the cleaning task after receiving the "start cleaning" instruction. It should be noted that the method of issuing the instruction includes, but is not limited to, the user issuing the instruction through software or applet, issuing the instruction through the control system on the cleaning device 20 or base station 10, the instruction being triggered by a preset time or the achievement of preset parameters. This application embodiment does not limit this, nor is it limited to the above examples.

[0123] S200: Control the cleaning equipment to enter spray mode and spray water mist onto the surface to be cleaned behind the machine.

[0124] Specifically, the water spraying device 400 in the cleaning equipment 20 delivers water from the clean water tank 300 into the first water channel 21, and sprays water mist through the first water channel 21 onto the surface A to be cleaned behind the machine body 100. In this way, the surface A to be cleaned can have a high water content, which is convenient for subsequent cleaning.

[0125] S300: Control the body of the cleaning equipment to move backward along the preset travel direction to the surface to be cleaned, and move back and forth so that the cleaning parts of the cleaning equipment repeatedly clean the surface to be cleaned.

[0126] As can be seen from the above, the cleaning component 200 (i.e., the roller) can repeatedly clean the surface A to be cleaned after spraying, so as to achieve the effect of cleaning key stains.

[0127] Through the aforementioned control method, the cleaning device 20, by reciprocating backward motion, can extend the residence time of the cleaning component 200 in the heavily soiled area. Furthermore, the cleaning component 200 can improve the efficiency of stain removal through repeated forward and reverse friction with the stains. This control method solves the technical problem of poor cleaning effect for heavily soiled stains in related technologies without adding hardware.

[0128] It should be noted that during the reciprocating movement of the cleaning equipment 20, the water spraying device 400 can continue spraying or stop spraying as needed to improve the utilization rate of the liquid in the clean water tank 300.

[0129] As an optional implementation, the cleaning device 20 is also provided with an identification element, which is directed to the surface A to be cleaned and is used to identify the target dirty area on the surface A to be cleaned.

[0130] It should be noted that the target dirty area can refer to stubborn stains, such as soy sauce, oil stains, or stubborn, fixed dirt such as grime.

[0131] It is understood that the identification components include, but are not limited to, image recognition modules, infrared recognition modules, lidar modules, and ultrasonic modules.

[0132] For example, the image recognition module can acquire an image of the surface A to be cleaned in real time, and determine whether it matches the target dirty area through a chip electrically connected to the image recognition module.

[0133] For example, the infrared recognition module can emit an infrared signal of a fixed wavelength towards the surface A to be cleaned, and receive the infrared signal reflected by the surface A. The difference between the received and emitted signals is used to determine whether the area matches the target dirty area. Generally, the target dirty area will absorb or scatter the infrared signal, resulting in a lower intensity of the received infrared signal.

[0134] For example, the lidar module can emit a beam to scan the contour of the surface A to be cleaned, and determine whether it matches the target dirty area based on the contour shape. Generally speaking, the surface height of the target dirty area will be higher than that of the surface A to be cleaned.

[0135] For example, the ultrasonic module can emit ultrasonic signals towards the surface A to be cleaned and receive the ultrasonic signals reflected from surface A. It determines whether the received signal matches the target dirty area based on the difference in frequency or intensity between the received and emitted signals. Generally, the target dirty area will change the propagation speed and reflection frequency of the ultrasonic waves.

[0136] It should be noted that the identification method of the identification component is not the focus of this application embodiment, and the above embodiments only provide some applicable solutions. Other solutions for identifying stains can be applied to this solution.

[0137] Reference Figure 4 In some embodiments, prior to step S200, the control method further includes:

[0138] S110, Control the operation of the identification device. During the cleaning operation, the identification device can work synchronously with the cleaning equipment 20.

[0139] S120. Determine whether the cleaning equipment has entered spray mode based on the identification device. It is understood that the method by which the identification device determines the cleaning equipment 20 has already been described above and will not be repeated here.

[0140] S130. If the identification device detects the target dirty area, proceed to step S200.

[0141] If the identification device fails to identify the target dirty area, proceed to step S100.

[0142] Step S200 may include:

[0143] S210, Control the water spray device of the cleaning equipment to spray water towards the target dirty area. In this way, the water spray device 400 can spray water mist onto the target dirty area, thereby increasing the humidity of the target dirty area, and the water mist can facilitate the removal of stains by the cleaning component 200.

[0144] As can be seen from the foregoing, when the water spraying device 400 sprays water mist toward the surface A to be cleaned, the cleaning device 20 enters step S300.

[0145] That is, step S300 may include:

[0146] S310: The control body moves backward along a preset travel direction to the target dirty area and moves back and forth, so that the cleaning component of the cleaning equipment repeatedly cleans the target dirty area. It should be noted that during steps S300 and S310, the identification component can continue to work to identify whether the stains in the target dirty area have been cleaned.

[0147] With the above settings, as the cleaning device 20 reciprocates to clean the surface A, the identification component maintains cleaning of the target dirty area until the target dirty area can no longer be identified by the identification component. At this point, the cleaning device 20 exits the spray mode and continues cleaning the surface A. The identification component allows the cleaning device 20 to adaptively clean according to the actual condition of the surface A, providing high versatility and improving the user experience.

[0148] In addition, the cleaning device 20 provided in this application embodiment can first soften stubborn stains with a spray when encountering them; then clean them by stacking a moistened cleaning component 200 (such as a roller), which greatly improves the cleaning effect.

[0149] Reference Figure 2 As an optional implementation, the water spraying device 400 includes a drive assembly 410 and a nozzle 420 located in the first water passage 21, the nozzle 420 having the aforementioned first nozzle 211.

[0150] It is understood that the nozzle 420 is located at the output end of the first water path 21 and is used to atomize the liquid. It should be noted that the shape of the nozzle 420 can be varied. For example, the nozzle 420 may have a flow channel that first contracts and then expands to increase the spray pressure, thereby increasing the diffusion area of ​​the water mist and extending the spray position. Another example is that the nozzle 420 may have a porous array structure, meaning it has multiple first nozzles 211. These multiple first nozzles 211 can form a denser water mist, further increasing the water volume and improving the wetting of stains, thus enhancing the cleaning effect of the cleaning device 20.

[0151] When the cleaning device 20 is in spray mode, the drive assembly 410 is used to transfer the liquid in the clean water tank 300 to the nozzle 420 and spray water mist through the nozzle 420.

[0152] It is understood that the nozzle 420 can be fixed to the outside of the body 100 or can be movably disposed on the outside of the body 100. For example, the nozzle 420 can be rotated by a motor to provide different tilt angles to adapt to different stain distribution patterns.

[0153] The specific process is as follows:

[0154] The drive assembly 410 serves as a power source, providing pressure potential energy. The first water passage 21 transmits the liquid and the pressure supplying the liquid flow to the nozzle 420. The nozzle 420 can complete a phase transition, releasing the supplied water flow through the first nozzle 211 and forming a water mist.

[0155] In the above process, without the drive component 410, the liquid flows out solely by gravity and cannot form a stable atomization; without the nozzle 420, the first nozzle 211 sprays out a water column with a small coverage area, which cannot meet the user's needs. Of course, the first water path 21 needs to have a good sealing effect. If the first water path 21 has throttling or leakage, the pressure output by the drive component 410 cannot be effectively transmitted to the nozzle 420, and the nozzle 420 cannot spray water mist or the water mist effect is poor.

[0156] The cleaning device 20 provided in this application embodiment atomizes liquid through a nozzle 420 and sprays it onto the target dirty area through a first nozzle 211 located on the rear side of the main unit. The water mist can quickly wet and penetrate the stain layer, softening the stain and reducing its adhesion. Combined with the reversible and reciprocating movement of the main unit, the cleaning component 200 (such as a roller) repeatedly passes over the target dirty area, achieving high-frequency wiping. Due to the large coverage area of ​​the water mist and its rapid penetration rate with the stain, it has a higher water output compared to the cleaning device 20 in related technologies, which can fully wet the stain and improve the cleaning effect.

[0157] In addition, the cleaning device 20 provided in this application embodiment can first soften stubborn stains with a spray when encountering them; then clean them by stacking a moistened cleaning component 200 (such as a roller), which greatly improves the cleaning effect.

[0158] Reference Figure 2 As an optional implementation, the water spraying device 400 also includes a water spray plate 430 located in the second water passage 22, the water spray plate 430 having a second nozzle facing the cleaning member 200.

[0159] Specifically, the spray plate 430 refers to the water outlet component located at the output end of the second water channel 22 and facing the cleaning component 200 (such as a roller). The spray plate 430 has multiple second nozzles. These multiple second nozzles can extend and be arranged along the axial direction of the roller to uniformly spray liquid onto different positions of the cleaning component 200.

[0160] A control component 440 is connected between the first water passage 21 and the second water passage 22, and the control component 440 is connected to the drive component 410. It is understood that the control component 440 can have a fluid on / off / diversion mechanism with at least two input ports and two output ports. For example, the control component 440 may include a mechanical three-way valve, a solenoid two-position three-way valve, a proportional throttle valve, or an integrated multi-way valve block, etc. The change of liquid flow direction is achieved by switching internal channels. Another example is that the control component 440 may also be composed of multiple independent solenoid valves arranged in parallel, connected to a common pipeline. Each valve is controlled independently, thereby supporting fine-grained timing control and flow distribution.

[0161] The control component 440 is used to selectively connect the liquid transmitted by the drive component 410 to at least one of the nozzle 420 and the spray plate 430 to spray the liquid onto the surface A to be cleaned and / or the cleaning component 200. Specifically, at least one port of the control component 440 is connected to the first water path 21 and at least one port is connected to the second water path 22, and all ports are within the same pressure range, thereby ensuring that the liquid can be arbitrarily switched between the two paths via the control component 440 under the action of the drive component 410. It is understood that this connectivity allows the control component 440 to be located anywhere downstream of the clean water tank 300, including but not limited to being adjacent to the outlet of the drive component 410, embedded inside a tee connector, or integrated into the base of the nozzle 420 / spray plate 430.

[0162] Specifically, after the drive component 410 is started, the liquid in the clean water tank 300 is pressurized and transported to the input port of the control component 440. The control component 440 then opens the corresponding pathway according to preset logic.

[0163] For example, when only surface A needs to be sprayed, the first water path 21 is connected to the nozzle 420, and the second water path 22 is closed. In another example, when only the cleaning component 200 needs water supply, the second water path 22 is connected to the spray plate 430, and the first water path 21 is closed. When the spray plate 430 and the nozzle 420 need to work together, both paths are opened simultaneously.

[0164] Understandably, the water spray plate 430 sprays liquid onto the surface of the cleaning component 200 through the second nozzle, which can increase the wettability of the cleaning component 200 on the basis of the water mist sprayed by the nozzle 420. Especially during the rotation of the cleaning component 200, the liquid is prone to splashing. The setting of the water spray plate 430 can maintain a stable water film covering the cleaning component 200, improve the dissolution rate of stains, increase the water carrying capacity of the cleaning component 200, and help improve the cleaning effect of the cleaning equipment 20.

[0165] When the cleaning device 20 identifies the target dirty area and enters the spray mode, the control component 440 can first open the first water path 21 for pre-wetting. After the stains on the surface to be cleaned A are softened, it can switch to the second water path 22 to continuously replenish water to the cleaning component 200, ensuring that it maintains a high moisture content and cleaning activity during repeated mopping. Alternatively, during the regular cleaning phase, the control component 440 can open the second water path 22 to provide the cleaning component 200 with a stable water source, while the first water path 21 remains closed to reduce energy consumption and noise.

[0166] With the above configuration, this embodiment of the application, without adding a water pump, can selectively supply liquid to the surface to be cleaned A (via nozzle 420) and the cleaning component 200 (via spray plate 430) using only one set of drive assembly 410 and control assembly 440. This configuration solves the technical problem in related technologies where traditional cleaning equipment 20 suffers from poor cleaning effect and water waste due to its single water circuit function, inability to simultaneously handle the pretreatment of the surface to be cleaned A and the maintenance of humidity in the cleaning component 200. It also features high functional integration, minimal volume variation, and high energy efficiency.

[0167] As an alternative implementation, the control method of the control component 440 may vary when the cleaning device 20 is in spray mode.

[0168] In some embodiments, when the cleaning device 20 is in spray mode, the control component 440 controls both the first water path 21 and the second water path 22 to be connected to the drive component 410. The drive component 410 is used to transfer the liquid in the clean water tank 300 to the first nozzle 211 and the second nozzle, and the second nozzle sprays liquid later than the first nozzle 211. At this time, both the first water path 21 and the second water path 22 are connected, and the cleaning device 20 can maintain a high humidity of the cleaning component 200 while increasing the humidity of the surface A to be cleaned. The nozzle 420 and the spray plate 430 can be used together to deal with stubborn stains that are difficult to clean.

[0169] It should be noted that the second nozzle spraying liquid later than the first nozzle 211 means that after the spray mode is activated, the first nozzle 211 opens first and sprays continuously for a preset period of time. This preset period of time can be dynamically adjusted according to the material of the surface A to be cleaned (such as tile, wood flooring, carpet), the ambient temperature and humidity, and the type of stain (dry dust, sticky oil stains, biological residue). After the nozzle 420 finishes spraying, the control component 440 then opens the second water path 22, causing the second nozzle to start spraying water.

[0170] In some embodiments, the aforementioned preset time period can be implemented by the timing module built into the controller, or the second nozzle can be triggered to open after the outlet pressure of the first nozzle 211 reaches a threshold. It can also be adaptively set by combining the target dirty area area and concentration parameters output by the image recognition module. All of these are technical concepts covered by this embodiment.

[0171] In some other embodiments, the control component 440 controls the first water path 21 to be connected to the drive component 410 while the second water path 22 is not connected to the drive component 410. The drive component 410 is used to transfer the liquid in the clean water tank 300 to the first nozzle 211. At this time, only the first water path 21 is open, and the second water path 22 is physically shut off or depressurized. For example, the second water path 22 can be closed by shutting off the solenoid valve on the second water path 22. At this time, all the driving energy of the drive component 410 is supplied to the first water path 21, ensuring that the first nozzle 211 obtains a high flow rate and a better atomized particle size, which is beneficial to forming a uniform water mist with a long suspension time.

[0172] Reference Figure 5 As an optional implementation, the control component 440 includes a three-way valve 441, a first valve 442, and a second valve 443. The three-way valve 441 is a fluid diversion device with a Y-shaped or T-shaped internal channel. The first valve 442 and the second valve 443 can be of any type, such as a solenoid valve, a pneumatic valve, or an electric valve. For example, both the first valve 442 and the second valve 443 can be two-position two-way solenoid water valves.

[0173] Reference Figure 5 The drive assembly 410 includes a one-way valve 411, an air pump 412, and a third valve 413. The air pump 412 is connected to the clean water tank 300 through the third valve 413 and the one-way valve 411.

[0174] The air pump 412 is electrically connected to the first valve 442, the second valve 443, and the third valve 413. That is, the air pump 412 can share the same control circuit module with the first valve 442, the second valve 443, and the third valve 413. The timing is coordinated by the main control MCU (microcontroller unit). For example, when the spray mode is started, the main control first turns on the third valve 413 and starts the air pump 412. After the air pressure in the clean water tank 300 stabilizes and rises to the preset value, the first valve 442 (supplying the nozzle 420) or the first valve 442 and the second valve 443 (supplying the nozzle 420 and the spray plate 430) are turned on in sequence.

[0175] The one-way valve 411 can be a mechanical spring-loaded check valve, used to allow compressed gas to flow unidirectionally from the air pump 412 into the clean water tank 300, preventing liquid in the clean water tank 300 from flowing back into the air pump 412 cavity under no-pressure or negative-pressure conditions, thus avoiding damage to the air pump 412 or contamination of the air path. The air pump 412 can be a miniature DC diaphragm air pump 412, with adjustable output air pressure to adapt to different spray particle size requirements. The third valve 413 is a two-position two-way solenoid valve, connected in series between the air pump 412 and the one-way valve 411, used to control whether compressed gas enters the clean water tank 300. The third valve 413 works in conjunction with the air pump 412 to ensure that gas is only input during periods of required pressurization, improving energy efficiency and extending the service life of the air pump 412.

[0176] Reference Figure 5 The first end of the three-way connector 441 is connected to the clean water tank 300. The nozzle 420 is connected to the second end of the three-way connector 441 via a first valve 442. The spray plate 430 is connected to the third end of the three-way connector 441 via a second valve 443. That is, the first valve 442 is connected in series between the second end of the three-way connector 441 and the nozzle 420, and is used to control the opening and closing of the nozzle 420. The second valve 443 is connected in series between the third end of the three-way connector 441 and the spray plate 430, and is used to control the opening and closing of the spray plate 430.

[0177] Air pump 412 is used to provide gas to transfer liquid in water tank 300 to nozzle 420 and / or spray plate 430.

[0178] Specifically, when the cleaning equipment 20 enters the spray mode, the main controller issues a spray command, the third valve 413 and the first valve 442 open synchronously, the air pump 412 starts and charges the clean water tank 300 with air; after the pressure in the clean water tank 300 increases, the liquid reaches the nozzle 420 through the second end of the three-way fitting 441 and the first valve 442, forming a stable water mist;

[0179] When water spray cleaning component 200 is required, the third valve 413, the first valve 442, and the second valve 443 open simultaneously, the air pump 412 starts and charges the clean water tank 300 with air; after the pressure in the clean water tank 300 increases, the liquid reaches the nozzle 420 through the second end of the three-way component 441 and the first valve 442, forming a stable water mist; the liquid is simultaneously transported to the spray plate 430 through the third end and the second valve 443.

[0180] When water spraying is not required, the first valve 442, the second valve 443, and the third valve 413 are all closed, the air pump 412 stops, and the one-way valve 411 immediately cuts off the gas backflow. The residual pressure in the clean water tank 300 is naturally released through the nozzle 420 / spray plate 430. The aforementioned water spraying device 400 does not require continuous operation of the water pump and can operate on demand, reducing the power consumption and noise of the cleaning equipment 20, and avoiding valve blockage due to liquid residue.

[0181] The technical solution provided in this application embodiment, after identifying the target dirty area, the cleaning device 20 first moves forward past the area and then retreats to the corresponding position. At this time, the air pump 412 starts and injects compressed gas into the clean water tank 300 through the third valve 413 and the one-way valve 411, so that positive pressure is formed in the tank; the pressure drives the clean water to be diverted through the three-way component 441 and guided to the nozzle 420 through the first valve 442, forming a water mist covering the target dirty area on the rear side of the main unit; after the water mist wets the target dirty area, the cleaning component 200 repeatedly wipes the target dirty area as the main unit moves backward, completing the enhanced cleaning of the target dirty area.

[0182] During the above process, since the air pump 412 provides a controllable positive pressure rather than a continuous water flow, the nozzle 420 responds quickly to start and stop, and the possibility of dripping is small. The one-way valve 411 can prevent gas backflow, so the filling and replenishment of the clean water tank 300 will not affect the safety of the gas circuit.

[0183] Reference Figure 2 As an optional implementation, the cleaning device 20 also includes a scraper 500, which is located around the periphery of the cleaning component 200 and is used to scrape and wash the cleaning component 200. The scraper 500 can extend axially along the cleaning component 200, with its working edge conforming to or close to the outer periphery of the cleaning component 200. The scraper 500 can be made of elastic rubber or TPU material to balance deformation adaptability and scraping force. It should be noted that the scraper 500 can be installed downstream of the cleaning component 200 in the direction of rotation (i.e., the side where wastewater naturally flows when the cleaning component 200 rotates); alternatively, a multi-segment scraper 500 can be arranged circumferentially around a portion of the cleaning component 200 to enhance the coverage of the scraping.

[0184] Reference Figure 2 In some embodiments, the cleaning device 20 further includes a wastewater tank 600 for receiving wastewater after being scraped by the scraper 500. Specifically, the wastewater tank 600 is a concave collection chamber with its opening facing the water outlet direction of the scraper 500.

[0185] Reference Figure 2 The cleaning equipment 20 also includes a wastewater tank 700 for collecting wastewater. A wastewater trough 600 can be connected to the wastewater tank 700. For example, the wastewater tank 700 can provide negative pressure to draw wastewater from the wastewater trough 600.

[0186] Reference Figure 2 In some embodiments, the water spraying device 400 further includes a spray member 450 directed toward the wastewater tank 600, the spray member 450 being used to spray liquid to clean the wastewater tank 600.

[0187] In some embodiments, a liquid level sensor may be integrated inside the wastewater tank 600. When the liquid level is detected to reach a threshold, the control component 440 is triggered to start the spray component 450 for rinsing, thereby achieving cleaning on demand.

[0188] In some embodiments, the nozzle 420, the spray plate 430, and the spray element 450 are all connected to the control component 440; the control component 440 is used to selectively connect the liquid transmitted by the drive component 410 to at least one of the nozzle 420, the spray plate 430, and the spray element 450 to spray the liquid onto at least one of the surface to be cleaned A, the cleaning component 200, and the wastewater tank 600.

[0189] It is understood that at least one of nozzle 420, water spray plate 430 and spray element 450 refers to one, any two or all three of the aforementioned.

[0190] Specifically, the control component 440 can freely switch the connection and stop of multiple water channels. Its control strategies include, but are not limited to: connecting only the nozzle 420 to wet the surface A to be cleaned; connecting only the spray plate 430 to self-clean and wet the cleaning component 200; connecting only the spray component 450 to clean the wastewater tank 600; or connecting the nozzle 420 and the spray plate 430 simultaneously to repeatedly clean the target dirty area; or connecting the spray plate 430 and the spray component 450 simultaneously to clean the cleaning component 200 and the wastewater tank 600 during the cleaning process; or connecting the nozzle 420, the spray plate 430 and the spray component 450 simultaneously to clean the cleaning component 200 and the wastewater tank 600 while repeatedly cleaning the target dirty area.

[0191] With the above settings, the scraper 500 continuously scrapes to ensure that wastewater flows directionally into the wastewater tank 600, preventing wastewater from flowing back onto the surface to be cleaned A and affecting the cleaning effect. The spray component 450 can automatically clean the wastewater tank 600, eliminating the need for manual cleaning by the user and improving the user experience. Furthermore, by sharing the same control component 440 and drive component 410 with the nozzle 420, spray plate 430, and spray component 450, the cleaning of the wastewater tank 600 can be performed simultaneously with functions such as spraying towards the surface to be cleaned A and self-cleaning of the cleaning component 200, or operate independently, thereby improving water resource utilization. This solves the problem of wastewater easily accumulating in the scraper 500 and wastewater tank 600, causing secondary pollution or blockage, reducing odor, improving self-cleaning ability, and enhancing the user experience.

[0192] Reference Figure 6 As an optional implementation, the control component 440 includes a four-way valve 444, a fourth valve 445, a fifth valve 446, and a sixth valve 447. The fourth valve 445 and the fifth valve 446 are both two-position, two-way solenoid valves, and the sixth valve 447 can be an on / off valve. The drive component 410 includes a peristaltic pump 414 electrically connected to the fourth valve 445, the fifth valve 446, and the sixth valve 447. The peristaltic pump 414 can be a brushless DC-driven roller peristaltic pump, a diaphragm pump (equipped with a double-headed check valve), or a gear metering pump, etc. This application embodiment does not limit the specific type of peristaltic pump 414, nor is it limited to the above examples; it only needs to have bidirectional fluid supply capability for forward suction and reverse delivery.

[0193] The peristaltic pump 414 connects the clean water tank 300 to the first end of the four-way connector 444. Understandably, when the peristaltic pump 414 is working, it generates negative pressure by periodically squeezing the pump tube to draw liquid from the clean water tank 300, and then uses the elastic reset of the pump tube to create positive pressure to push it to the four-way connector 444. Because the peristaltic pump 414 only contacts the inner wall of the pump tube and does not directly contact the liquid, it is resistant to trace amounts of surfactants, disinfectants, or particulate impurities that may be present in the clean water tank 300, avoiding problems such as clogging, cavitation, or corrosion failure common in traditional impeller pumps.

[0194] The fourth valve 445 is connected to the second end of the nozzle 420 and the four-way connector 444. When the fourth valve 445 is open and the peristaltic pump 414 is running, clean water enters the nozzle 420 through the second end of the four-way connector 444 and the fourth valve 445. The water mist is formed in the nozzle 420 through the first nozzle 211 and sprayed onto the surface A to be cleaned.

[0195] The fifth valve 446 is connected to the third end of the spray plate 430 and the four-way connector 444. When the fifth valve 446 is open and the peristaltic pump 414 is running, clean water enters the spray plate 430 through the third end of the four-way connector 444 and the fifth valve 446, and is sprayed towards the cleaning component 200 through the second nozzle on the spray plate 430.

[0196] The sixth valve 447 is connected to the fourth end of the jetting component 450 and the four-way component 444. When the sixth valve 447 is open and the peristaltic pump 414 is running, clean water enters the jetting component 450 through the fourth end of the four-way component 444 and the sixth valve 447, and the jetting component 450 sprays water toward the sewage tank 600.

[0197] The peristaltic pump 414 is used to transfer liquid in the clean water tank 300 to at least one of the nozzle 420, spray plate 430, and spray element 450. That is, the peristaltic pump 414 acts as a drive source to provide kinetic energy to the fluid, thereby controlling the on / off state of three different functional water circuits through the four-way valve 444, the fourth valve 445, the fifth valve 446, and the sixth valve 447. The entire process can be completed solely through electrical signals without switching mechanical pipelines or replacing the pump body.

[0198] With the above configuration, this embodiment of the application, while maintaining the layout of the cleaning equipment 20, uses a peristaltic pump 414 instead of an air pump 412 as the driving core, combined with a four-way connector 444 and three independent solenoid valves to open and close the water circuit. The peristaltic pump 414 has characteristics such as leak-free operation, low noise, and bidirectional fluid control, and can simultaneously provide pressurized water spray and absorb wastewater, thereby improving the intelligence level of the cleaning equipment 20 and enhancing the user experience.

[0199] As can be seen from the foregoing, the base station 10 is equipped with a water tank 11, which can provide cleaning for the cleaning equipment 20.

[0200] Understandably, to ensure a certain level of lightweight design, the cleaning equipment 20 has a limited capacity for its clean water tank 300. Therefore, the cleaning equipment 20 typically requires frequent manual water replenishment; or it needs to dock with the base station 10 multiple times to replenish clean water. In this case, the docking position is low so that the liquid in the water storage tank 11 can enter the clean water tank 300 under the influence of gravity. However, the above-mentioned water replenishment speed is relatively slow, resulting in a longer overall cleaning cycle for the cleaning equipment 20.

[0201] Reference Figure 6 When the water spray device 400 of the cleaning equipment 20 includes a four-way valve 444, a fourth valve 445, a fifth valve 446, a sixth valve 447 and a peristaltic pump 414, the cleaning equipment 20 may also include a two-position three-way valve 460.

[0202] It is understood that the two-position three-way valve 460 has a first state and a second state, and the two-position three-way valve 460 can switch between the first state and the second state. Specifically, when the two-position three-way valve 460 is in the first state, the two-position three-way valve 460 is connected to the water storage tank 11, the clean water tank 300, and the peristaltic pump 414 respectively. When the two-position three-way valve 460 is in the second state, the two-position three-way valve 460 is connected to the water storage tank 11, the clean water tank 300, and the peristaltic pump 414 respectively. For example, the two-position three-way valve 460 can be a two-position three-way valve 460 with three ports, the three ports being the water storage tank 11, the clean water tank 300, and the peristaltic pump 414 respectively. The two-position three-way valve 460 can switch between the aforementioned two states to achieve communication between different structures.

[0203] When the two-position three-way valve 460 is in the second state, the cleaning device 20 can be used to selectively inject water into the nozzle 420, spray plate 430, and spray element 450 as described above.

[0204] When the two-position three-way valve 460 is in the first state, that is, when the peristaltic pump 414 is connected to both the water storage tank 11 and the clean water tank 300, the peristaltic pump 414 is used to draw liquid from the water storage tank 11 and deliver it to the clean water tank 300. For example, when the peristaltic pump 414 is started, the peristaltic pump 414 first provides negative pressure to the water storage tank 11 to draw clean water from the water storage tank 11 into the pump chamber; then it provides positive pressure to the clean water in the pump chamber and pushes it to the clean water tank 300, thereby realizing the filling of the clean water tank 300 by the water storage tank 11 on the base station 10 body.

[0205] With the above settings, when the cleaning device 20 connects to the base station 10, the two-position three-way valve 460 is controlled to connect with the water storage tank 11. The peristaltic pump 414 is activated, allowing the liquid in the water storage tank 11 to be drawn and transported to the clean water tank 300. This solves the problem of frequent manual water filling caused by the limited capacity of the clean water tank 300.

[0206] Furthermore, the peristaltic pump 414 can also be used to realize the spraying, water spraying and self-cleaning functions of the cleaning device 20, without the need to add a separate water injection unit to the base station 10 or the cleaning device 20, which can reduce the complexity of the cleaning system and thus reduce the manufacturing cost.
