Description

Technical Field

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

[0002] As living standards continue to improve, people's demand for cleaning equipment is increasing, especially in terms of the diverse functions required. To meet market demand, companies have developed various multi-functional cleaning equipment, such as washing machines that combine dust removal and cleaning functions.

[0003] The cleaning equipment includes at least a handheld unit, a floor brush assembly located at one end of the handheld unit, a clean water tank, and a wastewater tank. The clean water in the clean water tank is transferred to a spray mechanism on the floor brush assembly. When the floor brush assembly is in operation, the spray mechanism sprays water onto the roller brush of the floor brush assembly to wash away dust. The wastewater generated from washing the roller brush is drawn into the wastewater tank.

[0004] After cleaning, users can remove the wastewater tank from the handheld unit and empty the wastewater or drain it into the base station's recycling bin through a pipe. The wastewater tank is equipped with a switch valve to open or close the channel on the wastewater tank that connects to the base station's recycling bin.

[0005] However, because the sewage contains impurities, these impurities can easily cause blockages after the valve is opened and closed, resulting in the sewage in the sewage tank being unable to be discharged. Summary of the Invention

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0081] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0082] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0083] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0084] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0085] To meet diverse user needs, cleaning equipment is becoming increasingly multifunctional. It not only possesses traditional functions such as vacuuming and floor cleaning, but also features a self-cleaning function, which involves rinsing the roller brushes of its floor brush assembly with clean water and then sucking the wastewater generated during rinsing into a wastewater tank. Currently, users need to empty the wastewater from the tank themselves. To address this issue, this application provides a cleaning system.

[0086] To facilitate better understanding, the following will combine... Figures 1 to 10 This paper describes in detail the specific structure of each component of the cleaning system and the working principle of the entire machine using a specific embodiment. It should be noted that this embodiment uses a handheld cleaning device as an example to illustrate the working principle of the cleaning system; it is understood that the cleaning device of this application can also be an automatic cleaning device such as a robotic vacuum cleaner. Furthermore, Figure 1 and Figure 6 The solid line with an arrow indicates the direction of water flow.

[0087] Combination Figure 1 and Figure 2 The cleaning system of this application includes a base station and cleaning equipment, wherein the base station is configured to house the cleaning equipment.

[0088] The cleaning equipment includes a handheld part 10, a floor brush assembly 13 disposed at one end of the handheld part 10, and a clean water tank 11 and a wastewater tank 12 disposed on the handheld part 10.

[0089] The floor brush assembly 13 includes a housing 130, a roller brush 131 rotatably mounted on the housing 130, and a spray mechanism for spraying clean water from the clean water tank 11 onto the roller brush 131 to clean dust.

[0090] The cleaning equipment also includes a drive mechanism disposed on the handheld part 10 and configured to draw wastewater from the roller brush 131 into the wastewater tank 12. The wastewater is generated when the roller brush 131 is cleaned with clean water in the clean water tank 11, or when the cleaning equipment cleans the floor with clean water in the clean water tank 11.

[0091] In detail, the wastewater tank 12 is also provided with an air inlet 120, and the housing 130 of the floor brush assembly 13 is provided with an air duct 18. One port of the air duct 18 is connected to the cavity of the wastewater tank 12 through the air inlet 120, and the other port of the air duct opens towards the roller brush 131. The drive mechanism is used to transport the wastewater at the roller brush 131 to the wastewater tank 12 through the air duct 18. The blower assembly includes a floor brush motor 14 and an impeller driven by it.

[0092] In some embodiments, the drive mechanism includes a main fan assembly disposed on the body of the cleaning equipment. The main fan assembly is configured to create a negative pressure in the wastewater tank 12 when the cleaning equipment is cleaning, and under the action of the pressure difference inside and outside the wastewater tank 12, the wastewater at the roller brush 131 is sucked into the wastewater tank 12.

[0093] In other embodiments, the drive mechanism includes a cleaning equipment water pump disposed on the body of the cleaning equipment, the cleaning equipment water pump being disposed on the air duct 18 and configured to pump wastewater from the roller brush 131 into the wastewater tank 12 when the cleaning equipment is cleaning.

[0094] Combination Figure 3 and Figure 4 The wastewater tank 12 of this application is also provided with a docking mechanism 15, which includes a valve cavity 150 extending in the circumferential direction of the wastewater tank 12, and a sealing valve 153 pre-pressurized in the valve cavity 150.

[0095] The valve chamber 150 has a docking interface 152 for interfacing with a base station and a connecting port 151 for connecting to the sewage tank 12. The opening direction of the connecting port 151 is located in the radial direction of the sewage tank 12.

[0096] The sealing valve 153 has a first position and a second position, and is configured to move between the first position and the second position. When in the first position, the sealing valve 153 closes the connection port 151, and when the sealing valve 153 moves axially along the sewage tank 12 to the second position, the sealing valve 153 opens the connection port 151.

[0097] To better understand the structure of sewage tank 12, please refer to [the relevant documentation / reference]. Figure 5 ,in, Figure 3 This is a cross-sectional structural diagram of the sewage tank. Figure 5 After concealing the sealing valve and related components Figure 3 A cross-sectional view of the assembly. Additionally, it should be noted that the directional terms used in describing the structure of the sealing valve 153 in this document, "axial" refers to the direction of movement of the sealing valve 153 between the first and second positions, and "radial" refers to the direction approximately perpendicular to the axial direction.

[0098] When the cleaning equipment cleans the ground, the sealing valve 153 is in the first position, blocking the connection port 151. The cleaning equipment pumps clean water from the clean water tank to the working ground or the roller brush 131. The cleaning of stains on the working ground or the roller brush 131 generates wastewater, which is sucked into the wastewater tank 12 by the driving mechanism of the cleaning equipment. After cleaning, the cleaning equipment is stored on the base station, and the sealing valve 153 moves from the first position to the second position, opening the connection port 151. The wastewater in the wastewater tank 12 enters the valve chamber 150 of the docking mechanism 15 through the connection port 151, and finally is discharged into the base station through the docking interface 152.

[0099] For more details, please continue reading. Figure 4 In this embodiment, the valve cavity 150 is integrally formed on the body of the sewage tank 12. The sewage tank 12 has an installation port communicating with the valve cavity 150, through which the sealing valve 153 is installed. The sewage tank 12 also includes a sealing cap 19. After the sealing valve 153 is installed in the valve cavity 150, the sealing cap 19 is fixedly or detachably connected to the body to seal the installation port. The valve cavity 150 being integrally formed on the sewage tank 12 body simplifies the assembly process of the cleaning equipment.

[0100] Of course, in other embodiments, the valve cavity 150 can be manufactured and assembled from components independent of the sewage tank 12, and then installed on the sewage tank 12 in a fixed or detachable manner, as long as its connection port 151 is connected to the sewage tank 12, and its interface 152 is connected to the base station after the cleaning equipment is stored.

[0101] See also Figure 4 The sealing valve 153 includes a valve body 1530, a push rod 1531 extending from the valve body 1530, and a return spring 154; wherein, the return spring 154 is pre-pressed axially between the cover 19 and the valve body 1530 so that the valve body 1530 is in a first position under the elastic force of the return spring 154, that is, blocking the communication port 151.

[0102] Furthermore, the sealing valve 153 also includes a guide rod 155, one end of which is fixedly mounted on the sealing cover 19, and a return spring 154 is sleeved on the guide rod 155.

[0103] The push rod 1531 extends from the interface 152 of the valve cavity 150 and is configured such that when the push rod 1531 is subjected to an external force, it drives the valve body 1530 to move from the first position to the second position along the valve cavity 150 against the axial elastic force of the return spring 154, that is, to open the communication port 151.

[0104] See also Figure 4 In order to ensure the guiding effect of the guide rod 155, in this embodiment, when the valve body 1530 is in the first position, the guide rod 155 is basically kept in contact with the valve body 1530 to prevent the return spring 154 from deforming or twisting during compression.

[0105] In order to enable the valve body 1530 to move from the first position to the second position when it is subjected to external force, in this embodiment, a guide hole 15300 extending along the axial direction is provided on the valve body 1530. The guide hole 15300 is configured such that when the valve body 1530 moves to the second position after being subjected to external force and overcoming the elastic force of the return spring 154, the guide rod 155 can extend into the guide hole 15300.

[0106] Combination Figure 4 and Figure 5 In this embodiment, the valve body 1530 and the push rod 1531 are integrally formed. In order to prevent the valve body 1530 from falling out of the valve cavity 150 through the interface 152, the valve body 1530 and the push rod 1531 are connected by a conical shoulder. The valve cavity 150 has a conical mating surface 1500 that abuts against the conical shoulder. When the sealing valve 153 is in the first position, the sealing valve 153 and the valve cavity 150 abut against each other through the matching conical shoulder and the conical mating surface 1500.

[0107] Of course, in other embodiments, the sealing valve 153 and the valve chamber 150 can also be connected by a matching stepped shoulder and stepped mating surface, as long as the sealing valve 153 is prevented from falling out of the valve chamber 150.

[0108] As mentioned above, in the first position, the sealing valve 153 can seal the connection port 151 to prevent sewage from leaking out of the sewage tank 12.

[0109] To further enhance the sealing performance of the docking mechanism 15, in this embodiment, the docking mechanism 15 also includes a sealing ring 156, which is disposed on the end face of the communication port 151. In the first position, the valve body 1530 cooperates with the sealing ring 156, that is, the valve body 1530 presses the sealing ring 156 tightly on the end face of the communication port 151.

[0110] In detail, a sealing ring mounting groove 1501 is provided on the end face of the connecting port 151. The sealing ring 156 is pressed into the sealing ring mounting groove 1501, and its upper part extends out of the sealing ring mounting groove 1501. When the external force applied to the sealing valve 153 disappears, the return spring 154 pushes the sealing valve 153 to the first position. Under the radial pressure of the valve body 1530, the sealing ring 156 undergoes elastic deformation and is pressed between the end face of the valve body 1530 and the connecting port 151, thereby achieving a sealing function.

[0111] Furthermore, in this embodiment, the opening direction of the docking interface 152 of the docking mechanism 15 is located in the axial direction of the sewage tank 12. With this configuration, the opening direction of the docking interface 152 is consistent with the movement direction of the sealing valve 153. The sealing valve 153 can be a straight rod structure, which is simple in structure and easy to operate.

[0112] In existing technologies, traditional on / off valves are used to control the opening and closing of the sewage tank's discharge port. The opening direction of the valve port connected to the sewage tank on the traditional on / off valve is consistent with the extension direction of the valve core in the valve cavity, that is, the opening direction of the valve port is axial. When the valve core moves towards the valve port, the gap between the valve core and the inner wall of the valve cavity at the valve port gradually decreases until the valve core and the end face of the valve cavity are sealed, blocking the valve port. The water passage for impurities in the valve body is small and is easily blocked by impurities.

[0113] In this application, the opening direction of the connecting port 151 of the sewage tank 12 is located in the radial direction of the sewage tank 12, while the sealing valve 153 moves along the axial direction of the sewage tank 12. When the sealing valve 153 moves to the second position, the connecting port 151 is fully open, which can ensure that any impurities smaller than the diameter of the connecting port 151 can be smoothly discharged from the sewage tank 12 into the base station, reducing the risk of channel blockage, improving the smoothness of sewage discharge of the cleaning equipment, and greatly improving the user experience.

[0114] As mentioned earlier, the sewage in the sewage tank 12 of the cleaning equipment is directly discharged into the base station through the docking mechanism 15. However, since the sewage contains foreign objects such as dust, these foreign objects will adhere to the inner wall of the sewage tank 12 during the discharge process and cannot be cleaned.

[0115] Therefore, please continue to see Figure 4 In addition, the sewage tank 12 of this application is provided with a scraper 16 in the cavity that matches the shape of the inner wall of the sewage tank 12. The scraper 16 is configured to be controlled by a drive mechanism to move along the axial direction of the sewage tank 12 to scrape off foreign objects from the inner wall of the sewage tank 12.

[0116] In detail, in some embodiments, the drive mechanism may include a motor and a transmission mechanism configured to convert the rotation of the motor's armature shaft into linear reciprocating motion of the scraper 16.

[0117] For example, in some embodiments, the transmission mechanism can be a gear and rack transmission mechanism, in which the rack is set on the inner wall of the sewage tank 12, the scraper 16 is fixed on the gear meshing with the rack, and the armature shaft of the motor drives the gear to reciprocate along the rack, thereby driving the scraper 16 to scrape off foreign objects on the inner wall of the sewage tank 12.

[0118] In other embodiments, the transmission mechanism can be a ball screw and nut transmission mechanism, in which the screw is fixed on the inner wall of the sewage tank 12, and the scraper 16 is fixed on the nut block that is threaded with the screw. The armature shaft of the motor drives the screw to rotate, and the scraper 16 moves along the extension direction of the screw with the nut block, thereby scraping off foreign objects on the inner wall of the sewage tank 12. Adjusting the motor rotation direction can change the movement direction of the nut block, thereby making the scraper 16 reciprocate along the inner wall of the sewage tank 12.

[0119] Additionally, it should be noted that in this embodiment, the inner wall of the sewage tank 12 is a cylindrical structure that is approximately cylindrical, and the matching scraper 16 is a circular structure, with the scraper 16 always in contact with the inner wall of the sewage tank 12.

[0120] Combination Figure 4 and Figure 5 In this embodiment, a water spray pipe 17 is also provided on the top of the sewage tank 12. The water spray pipe 17 is configured to spray water onto the inner wall of the sewage tank 12. The water spray pipe 17 sprays water onto the inner wall of the sewage tank 12 to rinse away foreign objects on the inner wall.

[0121] The water spray pipe 17 is arranged around the inner wall of the sewage tank 12, and multiple water spray holes 170 are provided on the water spray pipe 17. With this arrangement, the water in the water spray pipe 17 can be sprayed onto the inner wall of the sewage tank 12 relatively evenly, so that the entire inner wall can be rinsed without any blind spots.

[0122] Furthermore, the angle α between the opening direction of the water spray hole 170 and the inner wall of the sewage tank 12 is between 0° and 90°. Each water spray hole 170 can spray water in a fan shape, so that the inner wall of the sewage tank 12 can be evenly flushed by water, making it cleaner.

[0123] In detail, combined Figure 5 and Figure 5aThe water spray nozzle 170 is tilted downwards and sprays water towards the inner wall of the sewage tank 12. The angle between the spray direction of the water spray nozzle 170 and the axis of the sewage tank 12 is α. The angle α can be from 0° to 90°, and the spraying effect is better when the angle α is in the range of 30° to 60°. It should be noted that the axis of the sewage tank 12 refers to the direction from the opening of the sewage tank 12 to the bottom of the tank.

[0124] Similarly, in order to match the inner wall of the sewage tank 12 in this embodiment, the water spray pipe 17 is a circular water spray pipe 17.

[0125] The water spray pipe 17 can directly use the clean water in the clean water tank 11 of the cleaning equipment to clean the sewage tank 12. For example, the water spray pipe 17 and the clean water tank 11 are connected by a water pump and a water pipe.

[0126] When the water pump is started, the clean water in the clean water tank 11 is pumped into the spray pipe 17, and then sprayed onto the inner wall of the waste water tank 12 through the spray hole 170. The water pump can be a water pump that is provided by the cleaning equipment to pump the clean water in the clean water tank 11 into the spray mechanism on the floor brush assembly 13, or it can be a dedicated water pump separately configured for the spray pipe 17.

[0127] In this embodiment, the wastewater tank 12 of the cleaning equipment is self-cleaning via a scraper 16 and / or a water spray pipe 17, eliminating the need for manual cleaning by the user. This provides great convenience, frees up the user's hands, and achieves true maintenance-free operation. Under the dual action of the scraper 16 and the water spray pipe 17, foreign matter on the inner wall of the wastewater tank 12 is thoroughly cleaned, preventing bacterial growth and effectively solving the problem of odor caused by long-term accumulation of foreign matter in the wastewater tank 12.

[0128] It is understandable that when cleaning the wastewater tank 12, either the scraper 16 or the spray pipe 17 can be selected, or both can be used in combination to achieve a better cleaning effect.

[0129] To achieve better self-cleaning, the water spray pipe 17 is located above the scraper 16. The scraper 16 continuously moves up and down to scrape away foreign matter on the inner wall, while the water spray pipe 17 sprays water onto the inner wall of the wastewater tank 12 from above the scraper 16, providing a water source for the scraper 16 to clean the inner wall and rinse away the foreign matter adhering to the scraper 16 and the inner wall of the wastewater tank 12, resulting in better self-cleaning. Alternatively, in some other embodiments, the water spray pipe 17 is disposed inside the scraper 16, and the surface of the scraper 16 has a water outlet that corresponds to and communicates with the spray holes of the water spray pipe; or, the inner cavity of the scraper 16 forms a water spray pipe, and the spray holes are formed on the surface of the scraper 16.

[0130] As mentioned above, when the cleaning equipment is stored in the base station, its sealing valve 153 is moved to the second position by external force, opening the connection port 151, and the cavity of the sewage tank 12 is connected to the base station to discharge the sewage in the sewage tank 12 into the base station for subsequent treatment.

[0131] Combination Figure 1 and Figure 2 The base station includes a base 20 and a wastewater inlet 2006 disposed on the base 20. When the cleaning equipment is placed on the base station, the interface 152 of the cleaning equipment is connected to the wastewater inlet 2006 of the base station, and the sealing valve 153 moves to the second position. For a better understanding of the specific structure of the base station, please refer to [reference needed]. Figure 6 and Figure 7 ,in, Figure 6 This is a cross-sectional view of the base station. Figure 7 This is a schematic diagram of the exploded structure of a base station.

[0132] In detail, the base 20 is provided with a push rod (not shown in the figure) that pushes the sealing valve 153 to the second position, and the size of the push rod is controlled so as not to affect the connection between the connection port 151 and the sewage inlet 2006. Before the base station houses the cleaning equipment, the push rod extends from the sewage inlet 2006 on the base 20, and its extension length is sufficient to push the sealing valve 153 from the first position to the second position.

[0133] Combination Figure 6 and Figure 7 In this embodiment, the base station also includes a recycling bin 21 and a flow channel connecting the wastewater inlet 2006 on the base 20 and the recycling bin 21. Furthermore, the base station includes a fan assembly 22 configured to create a negative pressure within the recycling bin 21 to draw wastewater from the wastewater tank 12 of the cleaning equipment into the recycling bin 21. For ease of understanding, please refer to [further details omitted]. Figure 8 , Figure 8 This is a 3D structural diagram of the recycling bin.

[0134] The recycling bin 21 has a water inlet 210 and an air outlet 211. The circulation channel is connected to the recycling bin 21 through the water inlet 210. The fan assembly 22 is configured to exhaust the air inside the recycling bin 21 to the external environment through the air outlet 211, so as to create a negative pressure inside the recycling bin 21. That is, the air inlet 120 of the fan assembly 22 and the air outlet 211 of the recycling bin 21 are connected through a duct, and the exhaust outlet of the fan assembly 22 is connected to the external environment.

[0135] When the blower assembly 22 is started, the air in the recovery tank 21 is discharged to form a negative pressure. Since the sewage tank 12 is connected to the external environment, under the action of the internal and external pressure difference, the sewage in the sewage tank 12 is sucked into the recovery tank 21 through the circulation channel.

[0136] In some embodiments, when the wastewater in the recycling bin 21 reaches a preset amount, the user can remove the recycling bin 21 from the base 20 and pour the water out directly from the inlet 210, or pour the wastewater out directly through the drain outlet 213 on the recycling bin 21. The drain outlet 213 can be plugged with a plug during the self-cleaning process of the wastewater tank 12. Alternatively, at least part of the upper surface of the recycling bin 21 is open, allowing the user to remove the recycling bin 21 from the base 20 and pour the wastewater out directly from the open portion. The recycling bin 21 can be pulled out from the base station 20, similar to a drawer.

[0137] In other embodiments, the drain outlet 213 of the recycling bin 21 is directly connected to the sewer through an external pipeline, and the sewage in the recycling bin 21 can be directly discharged into the sewer through the external pipeline, or a water pump can be installed on the external pipeline so that the water pump can discharge the sewage in the recycling bin 21 into the sewer.

[0138] Water may not be completely drained from the recycling bin 21. If the water is not completely drained, it can easily breed bacteria and produce odors. Therefore, this application defines the structure of the recycling bin 21.

[0139] In detail, combined Figure 6 and Figure 9 The bottom of the recycling bin 21 has a high-level water receiving area 214 and a low-level water storage area 215. The high-level water receiving area 214 is located directly below the water inlet 210 of the recycling bin 21, and a drain outlet 213 is provided at the low-level water storage area 215. A guide plate 216 is also provided at the bottom of the recycling bin 21, which is designed to guide water from the high-level water receiving area 214 into the low-level water storage area 215. Furthermore, the guide plate 216 also serves as a reinforcing rib to enhance the overall strength of the recycling bin 21.

[0140] More specifically, the high-level water receiving area 214 and the low-level water storage area 215 are connected by a first inclined surface 217, an intermediate connecting plane 218, and a second inclined surface 219 arranged sequentially along the water flow direction. The intermediate connecting plane 218 is located below the high-level water receiving area 214 and the two are connected by the first inclined surface 217, while the low-level water storage area 215 is located below the intermediate connecting plane 218 and the two are connected by the second inclined surface 219.

[0141] After the fan assembly 22 is started, the water entering the recycling tank 21 from the inlet 210 first reaches the high water receiving area 214, then flows along the first inclined surface 217 into the intermediate connecting plane 218, then continues to flow to the second inclined surface 219, and finally enters the low water storage area 215.

[0142] With this setup, there is a height difference between the high-level water receiving area 214 and the low-level water storage area 215, which ensures that most of the water will flow into the low-level water storage area 215, minimizing the amount of water remaining in the recycling tank 21.

[0143] Of course, in addition to directly discharging the water in the recycling bin 21 into the sewer, it can also be recycled and reused. In this embodiment, the recycling and reuse method is to use the water in the recycling bin 21 to rinse the roller brush 131 of the floor brush assembly 13.

[0144] In detail, the base station includes a storage base 2000, a cleaning channel, and a base station water pump 23; wherein, the storage base 2000 is configured to accommodate the floor brush assembly 13 of the cleaning equipment, the cleaning channel is used to connect the recycling bin 21 and the storage base 2000, and the base station water pump 23 is configured to pump water from the recycling bin 21 into the storage base 2000 through the cleaning channel to rinse the floor brush assembly 13.

[0145] As mentioned earlier, the sewage in the sewage tank 12 is relatively turbid and of poor quality, failing to meet the requirements for rinsing the floor brush assembly 13. In order to make the water quality meet the requirements for rinsing the floor brush assembly 13, in this embodiment, the sewage from the sewage tank 12 is filtered and purified twice. The first treatment is to filter out particulate matter in the sewage, and the second treatment is to purify the water to improve its quality.

[0146] For details, please refer to Figure 10 The base station also includes a filter assembly 24 and a purification device 25. The filter assembly 24 is installed in the flow channel of the base station to perform a first filtration treatment on the sewage before it enters the recycling bin 21. The purification device 25 is installed in the cleaning channel to perform a second purification on the water in the recycling bin 21 before it enters the collection seat 2000, thereby further improving its cleanliness.

[0147] To further improve the cleaning effect of the floor brush assembly 13, in this embodiment, the base station also includes a spray pipe 26, which is disposed on the cleaning channel and configured to spray water from the recycling bin 21 onto the floor brush assembly 13.

[0148] In detail, the spray pipe 26 is disposed on the base 20 and extends along the axial direction of the roller brush 131 of the floor brush assembly 13. The spray pipe 26 has a water inlet hole, which is connected to the cleaning channel and the recycling box 21. The spray pipe 26 also has a plurality of spray holes arranged sequentially at intervals along the axial direction of the floor brush assembly 13.

[0149] Start the base station water pump 23 and fan assembly 22. The sewage in the sewage tank 12 enters the flow channel through the sewage inlet 2006. In the flow channel, it is filtered for the first time by the filter assembly 24 to remove particulate matter in the sewage and form relatively clean water. Then it enters the recycling tank 21 and is pumped into the cleaning channel by the base station water pump 23. In the cleaning channel, it is purified for the second time by the purification device 25 to obtain even cleaner water. Finally, it is sprayed onto the floor brush assembly 13 through the spray holes of the spray pipe 26 to clean the floor brush assembly 13.

[0150] As mentioned above, in order to achieve the purpose of recycling and reusing the sewage in the sewage tank 12, the base station in this application includes functional components such as a base 20, a storage base, a recycling box 21, a filter assembly 24, a fan assembly 22, a base station water pump 23, and a purification device 25.

[0151] In some embodiments, these functional elements can be arranged relatively independently and then connected to each other through corresponding pipelines.

[0152] For example, the docking interface 152 of the docking mechanism 15 and the sewage inlet 2006 of the base 20 are directly docked or connected through a water pipe connector. The sewage inlet 2006 of the base 20 and the water inlet of the filter assembly 24 are connected through a water pipe and / or a water pipe connector. The water outlet of the filter assembly 24 and the water inlet 210 of the recycling box 21 are connected through a water pipe and / or a water pipe connector. The exhaust port 211 of the recycling box 21 and the air inlet of the fan assembly 22 are connected through a duct and / or a duct connector. The water inlet 212 of the recycling box 21 and the inlet of the base station water pump 23 are connected through a water pipe and / or a water pipe connector. The base station water pump 23 and the storage base 2000 are connected through a water pipe and / or a water pipe connector.

[0153] It is understandable that the scattered placement of various functional components in the above embodiments results in the base station occupying a large space and being placed in a messy and disorderly room, which can easily lead to a poor user experience.

[0154] Therefore, in this embodiment, the various functional components of the base station are integrated on the base 20, and the structure is arranged in a relatively compact and reasonable manner. The base station occupies little space, which can improve the user experience to a certain extent.

[0155] For details, see Figure 2 In this embodiment, the base 20 includes an upper base 200 and a lower base 201. The upper base 200 and the lower base 201 cover each other to form a storage cavity 2007. The recycling box 21 is stored in the storage cavity 2007, or the recycling box 21 is stored in the lower base 201.

[0156] The base station is assembled from two parts, which is easy to process and easy to clean the storage cavity 2007. That is, open the upper base 200 and the lower base 201 to clean the dust and foreign objects inside them, and then close them together.

[0157] In addition, the recycling bin 21 is also equipped with rotatable rollers. The recycling bin 21 can be taken out from the storage cavity 2007 or the lower base 201 or placed into the storage cavity 2007 or the lower base 201. The recycling bin 21 and the lower base 201 roll together, which reduces the wear caused by direct friction between the two. Moreover, pushing and pulling the recycling bin 21 does not require too much force.

[0158] In other embodiments, the base 20 is an integral structure, and the storage cavity 2007 is processed by casting, machining, injection molding, or other methods based on different materials and appropriate processes are selected.

[0159] The upper surface of the upper base 200 is provided with a groove that matches the shape of the floor brush assembly 13. The floor brush assembly 13 can be placed in the groove. When the floor brush assembly 13 is placed in the groove, the receiving seat 2000 is formed on the upper base 200.

[0160] See Figure 6 The upper base 200 is also provided with a first chamber 2001, a second chamber 2002, a third chamber 2003 and a fourth chamber 2004 that are independent of each other. The independent nature of each chamber means that the four chambers form their own independent areas and do not affect each other. Among them, the sewage inlet 2006, which is connected to the docking interface 152 of the docking mechanism 15, is connected to the first chamber 2001. The first chamber 2001 is connected to the second chamber 2002. The filter assembly 24 is located in the second chamber 2002. The second chamber 2002 is connected to the recycling bin 21. The fan assembly 22 is located in the third chamber 2003. The third chamber 2003 is connected to the recycling bin 21 and is connected to the external environment. The base station water pump 23 is located in the fourth chamber 2004. The fourth chamber 2004 is connected to the recycling bin 21 through the purification device 25. The purification device 25 and the water inlet of the base station water pump 23 are connected through a water pipe. The water outlet of the base station water pump 23 is connected through a pipe that passes through the upper base 200 and the water inlet of the spray pipe 26.

[0161] When the fan assembly 22 is started, a negative pressure is formed in the recycling tank 21. The sewage in the sewage tank 12 enters the first chamber 2001 through the sewage inlet 2006, and then enters the second chamber 2002. In the second chamber 2002, it is filtered by the filter assembly 24 and then enters the recycling tank 21. At the same time, or after the water level in the recycling tank 21 reaches the preset value, the base station water pump 23 is started. The water in the recycling tank 21 is purified by the purification device 25 and then pumped into the spray pipe 26. It is then sprayed onto the floor brush assembly 13 through the spray hole to clean the floor brush assembly 13.

[0162] Furthermore, the first chamber 2001, the second chamber 2002, the third chamber 2003, and the fourth chamber 2004 are located on one side of the storage base 2000, with the second chamber 2002 and the third chamber 2003 arranged side by side. The first chamber 2001 and the fourth chamber 2004, when combined, are also arranged side by side between the second chamber 2002 and the third chamber 2003. The side-by-side arrangement of the second chamber 2002 and the third chamber 2003 is perpendicular to the side-by-side arrangement of the first chamber 2001 and the fourth chamber 2004. The base 200 forms an L-shaped structure, with the storage base 2000 located in its horizontal portion and the four chambers located in its vertical portion. In some embodiments, the first chamber 2001, the second chamber 2002, the third chamber 2003, and the fourth chamber 2004 are higher than the storage base 2000.

[0163] Referring again to the figure, in this embodiment, the upper base 200 also has a spray pipe receiving cavity 2005, and the spray pipe 26 is placed in the spray pipe receiving cavity 2005. The upper base 200 also has a spray hole at the corresponding position that communicates with the spray hole of the spray pipe 26.

[0164] Start the base water pump. The water in the recycling tank 21 is purified by the purification device 25 and then pumped into the spray pipe 26. It is then sprayed onto the floor brush assembly 13 through the spray holes on the storage base 2000.

[0165] To facilitate better understanding, the self-cleaning method of this cleaning system will be explained in detail below with examples of several application scenarios.

[0166] Application Scenario 1

[0167] When the cleaning equipment is stored in the base station and there is no sewage in its sewage tank 12, the motor of the cleaning equipment is started to drive the roller brush 131 of the ground brush assembly 13 to rotate. At the same time, the water pump of the cleaning equipment is started to pump the clean water in the clean water tank 11 of the cleaning equipment into the spray mechanism to clean the roller brush 131. Simultaneously or after a period of time, the fan assembly 22 of the base station is started to suck the sewage generated from cleaning the roller brush 131 into the recycling tank 21. Simultaneously or after a period of time, the water pump 23 of the base station is started to purify the water in the recycling tank 21 and pump it into the spray pipe 26 to spray it onto the roller brush 131 to clean the roller brush 131. Then, the water pump of the cleaning equipment is turned off to stop pumping the clean water in the clean water tank 11 into the roller brush 131. This cycle of cleaning the roller brush 131 continues until the roller brush 131 is clean. After that, the motor of the cleaning equipment, the fan assembly 22 of the base station, and the water pump 23 of the base station are turned off.

[0168] Application Scenario 2

[0169] When the cleaning equipment is stored in the base station, the wastewater tank 12 contains wastewater. The wastewater is obtained by sucking the wastewater generated by the cleaning equipment when cleaning the ground into the wastewater tank 12, and / or by the water spray pipe 17 rinsing the inner wall of the wastewater tank 12 with clean water from the clean water tank 11 when the cleaning equipment cleans the wastewater tank 12.

[0170] First, start the motor of the cleaning equipment to drive the roller brush 131 of the floor brush assembly 13 to rotate. At the same time, start the fan assembly 22 of the base station to suck the sewage in the sewage tank 12 into the recycling tank 21. Simultaneously or after a period of time, start the base station water pump 23 to purify the water in the recycling tank 21 and pump it into the spray pipe 26 to spray it onto the roller brush 131 to clean the roller brush 131. Repeat this process to clean the roller brush 131 until the roller brush 131 is clean. Then, turn off the fan assembly 22 and the water pump 23 of the base station.

[0171] Application Scenario 3

[0172] To facilitate understanding, the self-cleaning logic of the cleaning system will be explained in detail below, taking a specific self-cleaning cycle as an example, with reference to Table 1.

[0173] Table 1

[0174]

[0175] "ON" means the device is on, and "OFF" means the device is off.

[0176] For a duration of 0-120 seconds, the floor brush motor operates continuously, keeping the roller brush 131 inside the floor brush assembly 13 in a rotating state to facilitate the self-cleaning of the roller brush 131.

[0177] During the second duration, such as 0-10 seconds, the base station motor starts, putting the base station fan assembly 22 into operation and providing suction to draw the dirt (wastewater collected during the machine's cleaning of the ground) in the wastewater tank 12 into the base station's recycling tank 21.

[0178] During the third duration, such as 10-25 seconds, the base station motor is turned off, and the base station fan assembly 22 is in the off state. The base station water pump 23 is started to draw water from the recycling box 21 into the water spraying device, which sprays water to clean the roller brush 131, thus realizing the recycling of water.

[0179] The fourth duration, such as 0-25 seconds, coincides with the operation of the whole machine's water pump, which pumps the water in the clean water tank 11 to the roller brush 131 to clean the roller brush 131. The fourth duration is the sum of the second and third durations.

[0180] Fifth, within a duration of 25-30 seconds, the base station water pump 23 and the whole machine water pump are turned off, and the whole machine main motor is started to suck the sewage near the roller brush 131 of the ground brush assembly 13 into the sewage tank 12 to realize the recycling of dirt and grime, and to rinse the sewage tank 12.

[0181] Sixth, within a duration of 30-40 seconds, start the base station motor to put the base station fan assembly 22 into working condition, shut down the main motor of the whole machine, and suck the dirt (the sewage from the cleaning roller brush 131 that was just recycled) in the sewage tank 12 into the recycling tank 21.

[0182] For the seventh duration, such as 30-55 seconds, start the whole machine water pump to rinse the roller brush 131.

[0183] During the eighth time period, such as 40-55 seconds, the base station water pump 23 is started, the base station motor is turned off, and the base station fan assembly 22 is turned off. The water in the recycling box 21 is sucked into the spray pipe 26, and water is sprayed from the spray pipe 26 to clean the roller brush 131.

[0184] During the ninth period, such as 55-120 seconds, the base station water pump 23 is turned off, the whole machine water pump is turned off, and the whole machine main motor is started. The sewage near the roller brush 131 of the ground brush assembly 13 is sucked back into the sewage tank 12 to realize the recycling of dirt and filth, and the sewage tank 12 is rinsed.

[0185] During the tenth time interval, such as 120-130 seconds, the main motor and the ground brush motor of the whole machine are turned off, and the base station motor is started, so that the fan assembly 22 of the base station is in working condition, and the dirt in the sewage tank 12 is sucked into the recycling tank 21.

[0186] It should be noted that, for ease of understanding, in application scenario three, a self-cleaning cycle of 130 seconds is used to list the working status of each functional component of the cleaning system during different time periods within the cycle. It can be understood that the actual duration of the self-cleaning cycle of the cleaning system and the working duration of each functional component within the cycle can be adaptively adjusted by those skilled in the art according to the actual scenario.

[0187] The cleaning system of this application can self-clean the sewage tank and roller brush, and recycle the sewage in the sewage tank. After filtering and purifying the sewage, it is used to rinse the roller brush, which improves the automation level of the cleaning system, improves the user experience, and also improves the utilization rate of water resources and saves water resources.

[0188] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of the invention is defined by the appended claims.
