Detailed Implementation

[0104] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0105] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0106] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0107] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0108] To better meet the needs of household cleaning, cleaning systems with cleaning robots and cleaning base stations are gradually entering people's homes. In addition to charging the cleaning robot, the cleaning base station also has the function of cleaning the cleaning parts of the cleaning robot, so as to realize the self-cleaning of the cleaning robot.

[0109] During the self-cleaning process of the cleaning robot, the tray of the cleaning base station contains cleaning water, and the cleaning components are placed inside the tray. The self-cleaning is achieved by the rotation of the cleaning components. However, after cleaning the robot's cleaning components, some debris remains on the tray. This debris accumulates over a large area of ​​the tray, making manual cleaning inconvenient and degrading the user experience. Furthermore, excessive debris can clog the water filtration device inside the tray, requiring further effort from the user and further diminishing the user experience.

[0110] In view of this, embodiments of this application provide a cleaning tray and a cleaning base station and cleaning system having the cleaning tray, which aims to reduce the possibility of garbage clogging the water filter device by configuring a self-cleaning component in the cleaning tray to clean the garbage deposited in the tray.

The cleaning tray body 10 of this embodiment includes a bottom wall 11 and side walls 12 connected around the bottom wall 11. The bottom wall 11 and the side walls 12 together form a cleaning groove for cleaning the cleaning component 40. This embodiment does not impose too many limitations on the shape of the bottom wall 11 and the side walls 12. For example, the bottom wall 11 can be approximately circular, elliptical, rectangular, or a combination of the three. This embodiment will not list them all.

[0116] In some examples, optionally, the material of the cleaning tray body 10 in this embodiment can be plastic such as polyethylene or polypropylene, or other materials with certain structural strength, such as metal alloys. This embodiment will not list them all.

[0117] In this embodiment, the self-cleaning component 20 is installed on the bottom wall 11 of the cleaning tray body 10. The number of self-cleaning components 20 can be one or more. For example, when the number of cleaning components 40 is two and both cleaning components 40 can rotate, the number of self-cleaning components 20 in this embodiment is also two, and the two self-cleaning components 20 and the two cleaning components 40 can be arranged one-to-one relative to each other in position.

[0118] The self-cleaning component 20 of this embodiment includes a rotating part 21 and a scraping part 22. The rotating part 21 can be made of plastics such as polyethylene and polypropylene, or it can be a metal part or other polymer materials with a certain structural strength; these will not be listed individually in this embodiment. The scraping part 22 can be made of materials with elastic deformation capabilities, such as rubber, silicone, polyurethane, soft plastics, etc.

[0119] In this embodiment, the rotating member 21 is connected to the bottom wall 11 in a manner that allows it to rotate around its own axis. The axis of the rotating member 21 is perpendicular to the bottom wall 11. The rotation of the rotating member 21 around its own axis can be achieved by directly mounting the rotating member 21 on the bottom wall 11, or by using the support shaft 23 described below. The specific rotation structure is given below.

[0120] In this embodiment, the scraper 22 is fixedly connected to the rotating member 21 and abuts against the bottom wall 11. The rotation of the rotating member 21 drives the scraper 22 to scrape the bottom wall 11. The action of the scraper 22 can clean the garbage on the bottom wall 11 of the cleaning tray 100 and scrape the garbage to a specific area, such as the area on the bottom wall 11 near the side wall 12 and away from the water filter device. When the user cleans the cleaning tray 100, only this specific area needs to be cleaned. This not only makes it convenient for the user to clean the tray, but also reduces the possibility of garbage accumulating on the filter device and causing it to become clogged, ensuring that the self-cleaning function of the cleaning base station can operate normally.

[0121] In some examples, optionally, the end of the rotating member 21 facing away from the bottom wall 11 (the upper end in Figures 2-4) has a mating end face 2111 parallel to the bottom wall 11, and the mating end face 2111 is provided with a first friction structure 2112.

[0122] In some examples, optionally, the mating end face 2111 may be a platform 211 provided at the upper end of the rotating member 21. The platform 211 is integrally formed or integrally connected with the lower structure of the rotating member 21. The four edges of the platform 211 extend horizontally out of the rotating member 21 itself, so that the radial dimension of the platform 211 in the horizontal direction is greater than the radial dimension of the rest of the rotating member 21 in the horizontal direction. The aforementioned mating end face 2111 is the upper surface of the platform 211. The shape of the platform 211 may be circular, elliptical, rectangular, or polygonal, etc. This embodiment will not list them in detail.

[0123] When the mating end face 2111 of this embodiment is provided with a first friction structure 2112, the first friction structure 2112 can generate friction limit with the bottom of the cleaning component 40 placed in the tray, thereby enabling the rotation of the cleaning component 40 during self-cleaning to drive the rotation component 21 and the scraping component 22 of this embodiment to rotate. No additional power is required to drive the rotation of the rotation component 21. The structure is ingenious and realizes the multi-purpose function of the cleaning component 40.

[0124] Of course, the rotation drive of the rotating member 21 in this embodiment can also be that a motor or other driving member is installed on the bottom wall 11 (this embodiment is not shown in the figure), the output shaft of the motor is connected to the rotating member 21, and the rotation of the motor output shaft is used to drive the rotation of the rotating member 21 and the scraping member 22. However, this structure is more expensive and the overall structure of the cleaning disc 100 is more complex than the aforementioned configuration of the first friction structure 2112.

[0125] In addition, a handle, knob, or other structure can be provided on the mating end face 2111. After the cleaning component 40 has finished cleaning the cleaning plate 100, the user can hold the handle or hold the knob to drive the rotating component 21 and the scraping component 22 to rotate (this embodiment is not shown in the figure). Although this method does not require the configuration of a motor or other driving component, it requires user operation, and the garbage can only be scraped off the bottom wall 11 of the cleaning plate 100 after the cleaning component 40 has been cleaned. It cannot achieve garbage scraping during the cleaning process of the cleaning component 40, which reduces the user experience.

[0126] The first friction structure 2112 in this embodiment has various structural forms, such as a friction surface with tiny friction particles, a friction surface with pits, etc. In some examples, the first friction structure 2112 in this embodiment can optionally be a protruding structure provided on the mating end face 2111. A protruding structure refers to a structure that protrudes from the mating end face 2111, including protrusions, protrusions, ribs 21122, etc. Compared with a recessed structure, a protruding structure can reduce the possibility of residual cleaning wastewater on the mating end face 2111.

[0127] Furthermore, the protruding structure of this embodiment may include multiple first protrusions 21121. The cross-sectional shape of the first protrusions 21121 in this embodiment may be a circle as shown in the figure, or it may be a rectangle, triangle, irregular shape, etc. The protrusion height of the first protrusions 21121 may be between 1mm and 20mm, such as 1mm, 5mm, 10mm, 15mm, and 20mm. The maximum cross-sectional dimension of the first protrusions 21121 may be between 5mm and 30mm, such as 5mm, 15mm, 20mm, 25mm, and 30mm. There may be multiple sets of first protrusions 21121, each set including multiple first protrusions 21121 arranged at intervals. The multiple sets of first protrusions 21121 are arranged at intervals along the circumferential direction of the mating end face 2111 of the platform 211, and the distance between two adjacent sets of first protrusions 21121 is much greater than the spacing between two first protrusions 21121 located in the same set.

[0128] After the mating end face 2111 of the platform 211 in this embodiment comes into contact with the cleaning component 40, the dirty water during cleaning of the cleaning component 40 can flow out through the space between the protrusions. Compared with the friction structure of the pit, the dirty water remaining in the mating end face 2111 can be reduced.

[0129] In some examples, optionally, the first friction structure 2112 of this embodiment includes a plurality of raised ribs 21122 arranged circumferentially along the mating end face 2111. The shape of the raised ribs 21122 can be a straight line, an S-shape or an L-shape as shown in the figure, as long as the plurality of raised ribs 21122 can form a limiting groove 21123 and one end of two adjacent raised ribs 21122 forms an opening 21124 of the limiting groove 21123. Therefore, this embodiment does not impose too much limitation on the specific shape of the raised ribs 21122.

[0130] Taking the L-shaped rib 21122 in the figure as an example, there can be four ribs 21122. The four ribs 21122 are evenly spaced along the circumference of the mating end face 2111. The two ends of the ribs 21122 are respectively connected to the outer edge of the mating end face 2111, so that a water channel is formed between two adjacent ribs 21122. The four water channels and the space in the middle of the water channels form the limiting groove 21123. The four ribs 21122 form a cross-shaped limiting groove 21123. The cross-shaped limiting groove 21123 can accommodate at least part of the cleaning part and matches the shape and size of a part of the cleaning part.

[0131] In some examples, the first friction structure 2112 of this embodiment may optionally include a first convex 21121 and a rib 21122. In this case, in order to cooperate with the cross-shaped limiting groove 21123 structure, the first convex 21121 of this embodiment can be set as four groups, and the four groups of first convex 21121 are respectively located in the water channel formed by four pairs of adjacent ribs 21122.

[0132] Referring to Figure 4, in some examples, optionally, the scraping member 22 of this embodiment includes a scraping arm 221 and a scraping strip 222, wherein the scraping arm 221 has a first end 2211 and a second end 2212 opposite to each other, the first end 2211 is fixedly connected to the rotating member 21, and the connection method can be welding, integral connection, bonding, or the scraping arm 221 and the rotating member 21 are integrally formed during processing.

[0133] In this embodiment, the scraping arm 221 is mainly used to form a base for supporting and installing the scraping strip 222, and to allow the scraping strip 222 to be arranged along the length of the scraping arm 221, so as to ensure that the scraping range of the two scraping strips 222 of the two self-cleaning components 20 can cover most of the area of ​​the bottom wall 11 when rotating.

[0134] In this embodiment, the scraper 222 is attached side by side to the scraper arm 221 on the side facing the bottom wall 11 and abuts against the bottom wall 11. The scraper 222 and the scraper arm 221 can be connected by welding, bonding or by connecting components such as bolts.

[0135] In some examples, optionally, the second end 2212 of the scraping arm 221 in this embodiment is a free end, and the end of the scraper 222 facing away from the rotating member 21 extends out of the second end 2212 along the extension direction of the scraper 222. That is, the length of the scraper 222 in this embodiment is greater than the length of the scraping arm 221, so as to expand the garbage cleaning range of the scraper 222 in this embodiment. Specifically, the difference between the length of the scraper 222 and the length of the scraping arm 221 can be 1cm-10cm, such as 1cm, 3cm, 6cm, 8cm, and 10cm.

[0136] In some examples, optionally, the scraping arm 221 and the scraper 222 of this embodiment are both arc-shaped. The arc-shaped scraper 222 can collect the garbage during scraping, so that the garbage can be located inside the scraper 222, reducing the possibility of the garbage running around with the washing water during the garbage scraping process, and making it easier for the user to clean up afterwards.

[0137] Of course, the shape of the scraping arm 221 and the scraping strip 222 in this embodiment is not limited to this. For example, the scraping strip 222 and the scraping arm 221 can also be in the shape of a straight line, a door shape, an S shape, etc. This embodiment will not list them one by one.

[0138] Referring again to Figures 2 and 3, in some examples, the self-cleaning component 20 of this embodiment may optionally include a support shaft 23. The bottom wall 11 of the cleaning tray 100 of this embodiment is provided with a mounting groove. The lower end of the support shaft 23 is installed in the mounting groove of the bottom wall 11, and the lower part of the support shaft 23 is provided with a limiting flange 231. The limiting flange 231 is matched with the mounting groove to improve the stability of the support shaft 23 after installation.

[0139] In this embodiment, the rotating component 21 is coaxially connected to the support shaft 23. There are two possible rotation forms for the rotating component 21 and the support shaft 23 in this embodiment. One is that the support shaft 23 and the rotating component 21 are fixedly connected and rotate synchronously. In this case, a bearing (not shown in the figure) can be installed at the connection between the support shaft 23 and the mounting groove. The support shaft 23 can rotate on the bearing, and at the same time, the rotating component 21 and the scraper 22 rotate synchronously with the support shaft 23.

[0140] Another configuration is that the rotating component 21 can rotate around the support shaft 23. In this case, the lower end of the support shaft 23 is fixedly installed in the mounting groove, and the rotating component 21 is mounted on the upper middle part of the support shaft 23 through a bearing. The rotating component 21 can rotate on the support shaft 23 through the bearing, thereby achieving synchronous rotation of the rotating component 21 and the scraping component 22.

[0141] Of course, the rotating component 21 in this embodiment can also be in other ways with a structure that allows it to rotate around its own axis. For example, the rotating component 21 can be directly mounted on the bottom wall 11 through a bearing. This embodiment will not list them all.

[0142] Referring to Figures 1 and 5, in some examples, the cleaning tray 100 of this embodiment may optionally include a cleaning plate 30. The cleaning plate 30 may be installed on the bottom wall 11 or the side wall 12, or the cleaning plate 30 may be connected to both the bottom wall 11 and the side wall 12, as long as it does not affect the rotation of the rotating member 21 and the scraping member 22. This embodiment does not impose too many limitations on this.

[0143] In this embodiment, the scraping member 22 is located between the cleaning plate 30 and the bottom wall 11. The main function of the cleaning plate 30 is to contact the cleaning member 40 during self-cleaning. The cleaning effect of the cleaning member 40 is improved by the friction between the cleaning member 40 and the cleaning plate 30 when the cleaning member 40 rotates. Therefore, the horizontal height of the cleaning plate 30 in this embodiment can be level with or approximately level with the mating end face 2111 of the aforementioned platform 211. Therefore, a first through hole 31 needs to be provided in the cleaning plate 30. The first through hole 31 accommodates the end of the rotating member 21 facing away from the bottom wall 11 (i.e., the platform 211), so that the mating end face 2111 of the platform 211 can be level with or approximately level with the upper surface of the cleaning plate 30.

[0144] In this embodiment, the height of the side wall 12 should be higher than the height of the cleaning plate 30. When the cleaning tray 100 of this embodiment is filled with water, the water overflows the cleaning plate 30. Therefore, it is necessary to open a second through hole 32 on the cleaning plate 30. The second through hole 32 is large in size and has a large number of holes. The opening of the second through hole 32 makes the cleaning plate 30 form a hollow plate structure. The shape of the second through hole 32 can be a fan shape as shown in the figure, or it can be other shapes, such as circles, triangles, etc. This embodiment will not list them in detail.

[0145] In some examples, optionally, the surface of the cleaning plate 30 facing away from the bottom wall 11 is provided with a second friction structure 33, which cleans the cleaning component 40 (e.g., a rag) by the friction generated between the second friction structure 33 and the cleaning component 40, thereby improving the cleaning efficiency and effect of the cleaning component.

[0146] In some examples, the second friction structure 33 of this embodiment is optionally also a protruding structure, which includes a plurality of second protrusions 331 disposed on the mating end face 2111. The second protrusions 331 can have multiple rows and columns, and their distribution can be regular or irregular, as long as they can generate sufficient friction with the cleaning component 40 for self-cleaning.

[0147] Of course, the structure of the second friction structure 33 in this embodiment is not limited to a protruding structure. For example, it can also be a pit, or the surface of the cleaning plate 30 can be designed as a rough surface. This embodiment will not describe it in detail.

[0148] In some examples, the self-cleaning component 20 may optionally include a magnetic element 24 connected to the rotating component 21. The connection between the magnetic element 24 and the rotating component 21 may be by welding, bonding, embedding, or other methods. The magnetic element 24 is used to magnetically engage with the magnet (not shown) on the cleaning component 40 of the cleaning system, thereby increasing the connection force between the rotating component 21 and the cleaning component 40, making it easier for the self-cleaning component 20 to rotate under the drive of the cleaning component 40.

[0149] The following figures 1-6 describe the specific working process of the cleaning tray 100 in this embodiment:

[0150] When the cleaning component 40 (such as a rag or mop) at the bottom of the cleaning machine body needs to be self-cleaned, the cleaning tray 100 is filled with water, and the water level needs to exceed the mating end face 2111 of the cleaning plate 30 and the top of the rotating component 21. Then the cleaning component 40 is placed in the tray. A part of the cleaning component 40 is accommodated in the limiting groove 21123 formed by multiple protrusions 21122 of the mating end face 2111, and can generate a certain friction with the first protrusion 21121. The other part of the cleaning component 40 is in contact with the cleaning plate 30.

[0151] As the cleaning component 40 rotates, it performs self-cleaning through the friction between itself and the cleaning plate 30. At the same time, the cleaning component 40 can also drive the rotating component 21 and the scraping component 22 to rotate synchronously, scraping and cleaning the garbage on the bottom wall 11 of the cleaning disc 100, reducing the possibility of garbage accumulating on the bottom wall 11.

[0152] After the cleaning component 40 completes the self-cleaning process, the water in the cleaning tray 100 is filtered and recycled by the filtration device. The rotating component 21 and scraper 22 can still be rotated by the rotation of the cleaning component 40 for further debris removal. Finally, the rotation of the cleaning component 40 stops. This cleaning operation reduces the accumulation of debris on the bottom wall, thereby reducing the possibility of debris clogging the water filtration device (not shown in the figure). The user can then clean the scraped debris themselves, which is contained in the arc-shaped groove formed by the arc-shaped scraper 22 and the bottom wall 11, without needing to clean the entire bottom wall 11 of the tray.

[0153] Based on the cleaning tray 100 described above, this embodiment also provides a cleaning base station, including a base station body (not shown in the figure) and a cleaning base station 1000 as described in the above technical solution. The cleaning tray 100 is installed on the base station body. The cleaning tray 100 can be removed or detached from the base station body to facilitate cleaning of the cleaning tray 100 in this embodiment.

[0154] Based on the aforementioned cleaning base station, this embodiment also provides a cleaning system, including a cleaning robot (not shown in the figure) and a cleaning base station as described in the above technical solution. The cleaning robot is used to automatically clean the floor of the house, and the cleaning base station is used to charge and self-clean the cleaning robot. For details regarding the specific structure and cleaning principle of the cleaning robot, as well as the other structures of the cleaning base station besides the cleaning disc 100, please refer to relevant technologies, which will not be elaborated here.

[0155] Example 2

[0156] Please refer to Figures 12 and 13. This application embodiment provides a clean base station, including a base station body 200, a cleaning tray 100, and a self-cleaning component 20. The cleaning tray 100 is disposed on the base station body 200, and the self-cleaning component 20 is disposed on the cleaning tray 100. The self-cleaning component 20 is capable of collecting waste on the cleaning tray 100.

[0157] This application provides a cleaning system, including a cleaning base station 1000 and a cleaning device. The cleaning device includes a device body and a rag. The device body can drive the rag to clean stains attached to the ground. When the cleaning device is placed on a cleaning tray 100, the cleaning tray 100 can clean the stains on the rag.

[0158] It should be noted that the device itself drives a cloth to clean stains adhering to the ground, and the stains accumulate on the cloth. When the cleaning device returns to the base station and sits on the cleaning tray 100 after cleaning the ground, the cleaning tray 100 can clean the stains adsorbed on the cloth. Some water-soluble or small stains are washed away with water, while larger stains remain in the cleaning tray 100 or the self-cleaning component 20, where they dry and form waste. The remaining waste is then sucked into the self-cleaning component 20 to achieve self-cleaning of the base station.

[0159] For example, the cleaning device is a mopping robot, with two mop cloths, both of which are rotatably connected to the side of the device body closest to the ground. The device body can move on the ground, driving the mop cloths to rotate during movement to clean stains in various locations on the ground. The base station body 200 includes a charging terminal and a water spray nozzle. The mopping robot can automatically stop on the cleaning tray 100, the water spray nozzle can rinse the mop cloths of the mopping robot, and the charging terminal can charge the mopping robot. Some larger stains will remain on the cleaning tray 100, and after drying, they will form debris. The debris remaining on the cleaning tray 100 can be sucked in by the self-cleaning component 20.

[0160] Please refer to Figures 7-11. This application embodiment provides a self-cleaning component 20, including a housing 25, a vacuuming device 26, and a flywheel 27. The housing 25 has a receiving cavity 251, a first opening 252, and a second opening 253. The receiving cavity 251 communicates with the first opening 252 and the second opening 253, respectively. The vacuuming device 26 is disposed on the side of the second opening 253 away from the receiving cavity 251. The vacuuming device 26 is used to draw the receiving cavity 251 into a negative pressure state. The flywheel 27 is disposed inside the receiving cavity 251. The axis of the flywheel 27 intersects the direction of the suction airflow of the vacuuming device 26. The flywheel 27 can rotate to move the debris in the receiving cavity 251 toward the second opening 253.

[0161] In this embodiment, the vacuum cleaner 26 draws the receiving cavity 251 into a negative pressure state, so that the suction airflow of the vacuum cleaner 26 provides a force for the garbage in the receiving cavity 251 to move towards the second opening 253. The flywheel 27 disposed in the receiving cavity 251 can rotate to disturb the garbage and drive it towards the second opening 253. The vacuum cleaner 26 and the flywheel 27 cooperate with each other to improve the self-cleaning component 20's ability to collect garbage in the receiving cavity 251.

[0162] For example, the material of the housing 25 is not limited, and can be, for example, plastic or metal.

[0163] For example, the material of the flywheel 27 is not limited, and can be, for example, plastic or rubber.

[0164] For example, the position of the flywheel 27 within the receiving cavity 251 is not limited.

[0165] For example, referring to Figure 9, the flywheel 27 is disposed on the side of the receiving cavity 251 near the first opening 252.

[0166] For example, as shown in Figure 9, the axial direction of the flywheel 27 is set perpendicular to the direction of the suction airflow of the vacuuming device 26.

[0167] For example, the driving method for the rotation of flywheel 27 is not limited.

[0168] For example, the self-cleaning component 20 also includes a drive unit that can drive the flywheel 27 to rotate so as to move the debris in the receiving cavity 251 toward the second opening 253.

[0169] For example, the connection method between the vacuum cleaner 26 and the housing 25 is not limited.

[0170] For example, the vacuuming device 26 is disposed on the side of the second opening 253 away from the receiving cavity 251 and is sealed to the housing 25 to close the second opening 253.

[0171] For example, referring to FIG9, the vacuuming device 26 draws the cavity 251 into a negative pressure state, so that the suction airflow flows from the first opening 252 to the second opening 253.

[0172] In one embodiment, please refer to Figures 7-9. The flywheel 27 is rotatably connected to the housing 25. The flywheel 27 includes a flywheel body 271 and a fan blade 272 connected to the flywheel body 271. The suction airflow of the vacuuming device 26 can drive the fan blade 272 to rotate so as to move the garbage in the receiving cavity 251 toward the second opening 253.

[0173] In this embodiment, the fan blade 272 rotates under the action of the suction airflow from the vacuuming device 26. On the one hand, the fan blade 272 can disturb the garbage and move it towards the second opening 253. The vacuuming device 26 and the flywheel 27 cooperate with each other, which helps to improve the self-cleaning component 20's ability to collect garbage in the receiving cavity 251. On the other hand, the rotation of the fan blade 272 does not require an additional driving device and can rotate under the action of the suction airflow from the vacuuming device 26, which helps to reduce the power consumption of the self-cleaning component 20.

[0174] For example, the material of the fan blade 272 is not limited, and can be, for example, plastic or rubber.

[0175] For example, the material of the flywheel body 271 is not limited, and can be, for example, plastic or rubber.

[0176] For example, the connection method between the flywheel body 271 and the fan blade 272 is not limited.

[0177] For example, the flywheel body 271 is rotatably connected to the housing 25, and the fan blade 272 is fixedly connected to the flywheel body 271. The suction airflow of the dust collection device 26 acts on the fan blade 272, causing the fan blade 272 to drive the flywheel body 271 to rotate relative to the housing 25.

[0178] For example, the flywheel body 271 is rotatably connected to the housing 25, and the fan blade 272 is rotatably connected to the flywheel body 271. The fan blade 272 can rotate around the flywheel body 271. The suction airflow of the vacuuming device 26 acts on the fan blade 272, causing the fan blade 272 to rotate relative to the flywheel body 271.

[0179] In one embodiment, as shown in Figures 7-9, there are multiple fan blades 272, which are arranged at intervals along the circumference of the flywheel body 271.

[0180] In this embodiment, multiple fan blades 272 are arranged at circumferential intervals along the flywheel body 271, which increases the number of times the fan blades 272 pass over the trash within one rotation cycle of the flywheel 27, thereby increasing the frequency at which the fan blades 272 agitate the trash and move it towards the second opening 253. Within one rotation cycle of the flywheel 27, the fan blades 272 can agitate the trash multiple times and move it towards the second opening 253, which is beneficial to improving the self-cleaning component 20's ability to collect trash from the receiving cavity 251.

[0181] Understandably, the number of fan blades 272 is not limited.

[0182] For example, there is one fan blade 272, which agitates and moves the waste toward the second opening 253 once during one rotation cycle of the flywheel 27.

[0183] For example, please refer to Figure 9. There are three fan blades 272. The three fan blades 272 are evenly spaced along the circumference of the flywheel body 271. In one rotation cycle of the flywheel 27, each fan blade 272 can disturb and move the garbage to the second opening 253 once, so that the three fan blades 272 disturb and move the garbage to the second opening 253 a total of three times.

[0184] In one embodiment, referring to FIG9, the flywheel body 271 has an eccentric portion 2711, which is configured to cause the center of gravity of the flywheel 27 to deviate from the rotation center of the flywheel body 271.

[0185] For example, the eccentric portion 2711 may be located at the fan blade 272.

[0186] For example, the eccentric portion 2711 may be located at one end of the fan blade 272 that is radially away from the flywheel body 271, so as to increase the weight and thickness of the root of the fan blade 272, so that the center of gravity of the flywheel 27 is deviated from the rotation center of the flywheel body 271.

[0187] In this embodiment, the eccentric portion 2711 is configured to deviate the center of gravity of the flywheel 27 from the rotation center of the flywheel body 271, so that when the flywheel 27 is stationary, the flywheel 27 can have a fixed posture under the action of gravity, which makes it easier to adjust the fixed posture of the flywheel 27 in the stationary state, so as to avoid the flywheel 27 blocking the first opening 252, and thus allow the garbage to enter the receiving cavity 251 as much as possible, which is beneficial to improving the collection capacity of the self-cleaning component 20 for the garbage in the receiving cavity 251.

[0188] In one embodiment, please refer to FIG9, the flywheel 27 includes a flywheel body 271 and a fan blade 272 connected to the flywheel body 271. When the flywheel 27 is stationary, the fan blade 272 is located in the area outside the corresponding position of the first opening 252.

[0189] For example, referring to Figure 9, the flywheel 27 includes a flywheel body 271 and fan blades 272 connected to the flywheel body 271. The eccentric portion 2711 is located on the flywheel body 271 and is disposed between two adjacent fan blades 272. When the flywheel 27 is stationary, the fan blades 272 are located in the area outside the corresponding position of the first opening 252. The first opening 252 is located between the fan blades 272 on both sides of the eccentric portion 2711 along the circumference of the flywheel 27, so as to avoid the fan blades 272 blocking the first opening 252.

[0190] In this embodiment, the eccentric portion 2711 of the flywheel body 271 is disposed between two adjacent fan blades 272, so that the center of gravity of the flywheel 27 is offset from the rotation center of the flywheel body 271. When the self-cleaning component 20 is not working, there is no suction airflow from the vacuuming device 26 in the receiving cavity 251. The eccentric portion 2711 is always located below the flywheel body 271, so that the fan blades 272 on both sides of the eccentric portion 2711 can maintain a large distance from the first opening 252. The first opening 252 is located between the fan blades 272 on both sides of the eccentric portion 2711 along the circumference of the flywheel 27, so as to reduce the possibility that the fan blades 272 will obstruct the garbage from entering the receiving cavity 251 through the first opening 252, thereby allowing the garbage remaining on the cleaning disc 100 to enter the receiving cavity 251 through the first opening 252 as much as possible. When the self-cleaning component 20 starts working, the combined action of the suction airflow from the vacuum cleaner 26 and the rotating flywheel 27 facilitates the self-cleaning component 20 in sucking up more debris located in the receiving cavity 251. Debris remaining on the cleaning disc 100 can enter the receiving cavity 251 as early as possible, making it easier for the self-cleaning component 20 to collect more debris, thereby improving the self-cleaning component 20's debris collection capacity.

[0191] For example, referring to Figure 9, there are three fan blades 272. The three fan blades 272 are evenly spaced along the circumference of the flywheel body 271. The included angle between two adjacent fan blades 272 is 120°. The eccentric part 2711 of the flywheel body 271 is disposed between two adjacent fan blades 272 so that the center of gravity of the flywheel 27 is offset from the rotation center of the flywheel body 271. When the self-cleaning component 20 is not working, the flywheel 27 always maintains the eccentric part 2711 in the posture of being directly below the flywheel body 271 under the gravity of the eccentric part 2711. This makes the fan blade 272 located on the left side of the first opening 252 maintain a large distance from the first opening 252, so that the garbage remaining on the cleaning disc 100 can enter the receiving cavity 251 through the first opening 252 as much as possible. When the self-cleaning component 20 starts working, the fan blades 272 begin to rotate clockwise under the action of the suction airflow from the vacuuming device 26, causing the fan blades 272 to start to agitate and move more of the debris in the receiving cavity 251 toward the second opening 253. In one rotation cycle of the flywheel 27, each fan blade 272 can agitate and move the debris toward the second opening 253 once, so that the three fan blades 272 agitate and move the debris toward the second opening 253 a total of three times.

[0192] It is understandable that the flywheel body 271 may not have an eccentric part 2711. For example, the mass of the flywheel body 271 is evenly distributed along the circumference, and the number of fan blades 272 is three, which are evenly spaced along the circumference of the flywheel body 271.

[0193] It is understandable that the eccentric portion 2711 may also be provided across the flywheel body 271 and the fan blade 272, with the eccentric portion 2711 partially formed on the flywheel body 271 and partially formed on the fan blade 272.

[0194] In one embodiment, please refer to Figures 7-9, along the axial direction of the flywheel body 271, the fan blade 272 extends from one end of the flywheel body 271 to the other end of the flywheel body 271.

[0195] In this embodiment, the fan blade 272 extends from one end of the flywheel body 271 to the other end along the axial direction of the flywheel body 271, increasing the area of ​​the fan blade 272 and thus increasing the contact area between the fan blade 272 and the waste. This is beneficial to improving the efficiency of the fan blade 272 in disturbing and driving the waste in the receiving cavity 251 to move towards the second opening 253, thereby improving the waste collection capacity of the self-cleaning component 20.

[0196] For example, please refer to Figure 9. The number of fan blades 272 is three. The three fan blades 272 are evenly spaced along the circumference of the flywheel body 271. Along the axial direction of the flywheel body 271, the three fan blades 272 extend in a straight line from one end of the flywheel body 271 to the other end of the flywheel body 271.

[0197] For example, there are three fan blades 272. The three fan blades 272 are evenly spaced along the circumference of the flywheel body 271. Along the axial direction of the flywheel body 271, the three fan blades 272 extend spirally from one end of the flywheel body 271 to the other end of the flywheel body 271.

[0198] It is understandable that the arrangement of the fan blades 272 along the axial direction of the flywheel body 271 is not limited.

[0199] For example, the fan blade 272 includes a plurality of sub-blades, which are arranged at intervals along a straight line along the axial direction of the flywheel body 271, and the sub-blades corresponding to the plurality of fan blades 272 are evenly spaced along the circumference of the flywheel body 271.

[0200] For example, the fan blade 272 includes a plurality of sub-blades. Along the axial direction of the flywheel body 271, the plurality of sub-blades are arranged in a spiral interval, and the sub-blades corresponding to the plurality of fan blades 272 are evenly spaced along the circumference of the flywheel body 271.

[0201] It is understandable that the relationship between the length of the fan blade 272 along the axial direction of the flywheel body 271 and the length of the flywheel body 271 along the axial direction is not limited.

[0202] For example, the length of the fan blade 272 along the axial direction of the flywheel body 271 is less than the length of the flywheel body 271 along the axial direction, and the fan blade 272 is continuously extended along the axial direction of the flywheel body 271.

[0203] In one embodiment, please refer to Figure 9, the tilt direction of the end of the fan blade 272 away from the flywheel body 271 is opposite to the rotation direction of the flywheel body 271.

[0204] In this embodiment, the tilt direction of the end of the fan blade 272 away from the flywheel body 271 is opposite to the rotation direction of the flywheel body 271. On the one hand, this helps to concentrate the suction airflow of the vacuuming device 26 within the space enclosed by the two adjacent fan blades 272 and the flywheel body 271, increasing the force of the suction airflow on the fan blade 272, thereby increasing the force of the fan blade 272 disturbing and driving the garbage located in the receiving cavity 251 to move towards the second opening 253. On the other hand, the fan blade 272 is tilted away from the rotation direction of the flywheel body 271. During the rotation of the fan blade 272, air can slide over the surface of the fan blade 272 with less resistance, which helps to reduce the air resistance of the fan blade 272 rotation. The fan blade 272 is tilted away from the rotation direction of the flywheel body 271, which not only increases the force of the intake airflow on the fan blade 272, enabling the fan blade 272 to move the garbage in the receiving cavity 251 towards the second opening 253 with greater force, but also reduces the air resistance of the fan blade 272 rotation, which helps to increase the rotation speed of the fan blade 272, and thus helps to improve the garbage collection capacity of the self-cleaning component 20.

[0205] For example, referring to Figures 7-9, there are three fan blades 272, which are evenly spaced around the circumference of the flywheel body 271. Along the axial direction of the flywheel body 271, all three fan blades 272 extend in a straight line from one end of the flywheel body 271 to the other end. Under the action of the suction airflow from the vacuum cleaner 26, the suction airflow flows from the first opening 252 to the second opening 253, causing the flywheel 27 to rotate clockwise. Along the direction of the suction airflow, the fan blades 272 are arc-shaped, with the end of the fan blades 272 facing away from the flywheel body 271 tilted counterclockwise.

[0206] It is understandable that the arrangement of the fan blade 272 away from the flywheel body 271 is not limited.

[0207] For example, the fan blade 272 may be arranged radially along the flywheel body 271.

[0208] For example, the fan blade 272 is made of soft rubber and is arranged radially along the flywheel body 271. When the fan blade 272 rotates under the action of the suction airflow of the dust collection device 26, it takes the shape of an arc under the action of rotational inertia. The tilting direction of the end of the fan blade 272 away from the flywheel body 271 is opposite to the rotation direction of the flywheel body 271.

[0209] It is understandable that the relationship between the tilt direction of the end of the fan blade 272 away from the flywheel body 271 and the rotation direction of the flywheel body 271 is not limited. For example, the tilt direction of the end of the fan blade 272 away from the flywheel body 271 can also be the same as the rotation direction of the flywheel body 271.

[0210] In one embodiment, referring to FIG9, the receiving cavity 251 includes a guide cavity 2511, a transition opening 2512, and a transition cavity 2513. The first opening 252, the guide cavity 2511, the transition opening 2512, the transition cavity 2513, and the second opening 253 are sequentially connected. At least one cavity wall surface of the guide cavity 2511 is a first wall surface 25111. The guide cavity 2511 and the first opening 252 are both located below the first wall surface 25111. The first wall surface 25111 is arc-shaped. At least one opening of the transition opening 2512... The mouth wall is a second wall 25121 connected to the first wall 25111. The second wall 25121 is arc-shaped and tangent to the first wall 25111. At least one cavity wall surface of the transition cavity 2513 is a third wall 25131. The third wall 25131 is tangent to the second wall 25121. The position where the first wall 25111 and the second wall 25121 are connected is the target position. The angle between the tangent plane of the first wall 25111 at the target position and the third wall 25131 is an acute angle.

[0211] In this embodiment, the angle between the tangent plane of the first wall surface 25111 at the target position and the third wall surface 25131 is an acute angle. The second wall surface 25121 is arc-shaped and tangent to both the first wall surface 25111 and the third wall surface 25131. This results in the radius of the arc-shaped second wall surface 25121 being smaller than the radius of the arc-shaped first wall surface 25111, and the angle corresponding to the arc of the second wall surface 25121 being larger. Consequently, the second wall surface 25121 has a larger curvature, making it less likely for the garbage located in the receiving cavity 251 to be adsorbed onto the second wall surface 25121 with a larger curvature as the garbage moves from the first opening 252 to the second opening 253 under the combined action of the suction airflow of the vacuuming device 26 and the rotation of the fan blade 272. When the garbage passes through the transition opening 2512, it can slide smoothly from the second wall 25121 with a larger curvature into the transition cavity 2513 and then be sucked in by the vacuuming device 26, which helps to improve the efficiency of the self-cleaning component 20 in collecting garbage.

[0212] For example, please refer to Figure 9. The included angle shown by angle R1 in the figure is the included angle between the tangent plane of the first wall surface 25111 at the target position and the third wall surface 25131. The opening of the included angle between the tangent plane of the first wall surface 25111 at the target position and the third wall surface 25131 faces the second wall surface 25121.

[0213] For example, referring to Figure 9, along the direction of the suction airflow of the vacuum cleaner 26, the second wall surface 25121 is located on the side of the flywheel 27 close to the vacuum cleaner 26. The second wall surface 25121 is connected to the arc-shaped first wall surface 25111 and the third wall surface 25131 on both sides along the direction of the suction airflow of the vacuum cleaner 26, respectively. The size of the transition opening 2512 in the vertical direction is similar to the radial size of the flywheel body 271.

[0214] It is understandable that the relative arrangement of the first wall 25111, the second wall 25121 and the third wall 25131 is not limited.

[0215] For example, the first wall surface 25111, the second wall surface 25121 and the third wall surface 25131 may be located in the same plane.

[0216] In one embodiment, please refer to FIG9, the surface below the guide cavity 2511 is a guide surface 25112, the guide surface 25112 is arc-shaped, and the tangent plane of the guide surface 25112 on the side of the flywheel 27 away from the first opening 252 intersects with the second opening 253.

[0217] In this embodiment, the guide surface 25112 is arc-shaped. The tangential plane of the guide surface 25112 on the side of the flywheel 27 away from the first opening 252 intersects with the second opening 253. On the one hand, during the rotation of the fan blade 272, the fan blade 272 can cooperate with the arc-shaped guide surface 25112 for a longer distance. During the process of the fan blade 272 driving the garbage located in the receiving cavity 251 to move along the guide surface 25112 towards the second opening 253, the distance that the fan blade 272 and the guide surface 25112 jointly abut against the garbage is longer. This is beneficial to extending the distance and time that the fan blade 272 drives the garbage towards the second opening 253, thereby benefiting... The fan blades 272 are used to move the debris towards the second opening 253. On the other hand, the guide surface 25112, located on the side of the flywheel 27 away from the first opening 252, intersects with the second opening 253. When the fan blades 272 move the debris towards the second opening 253 to the transition opening 2512, the direction of the debris's movement speed also intersects with the second opening 253 under the influence of the rotating fan blades 272 and the restriction of the guide surface 25112. Under the action of the suction airflow of the vacuum cleaner 26, the debris can be sucked into the vacuum cleaner 26 through the second opening 253, which helps to improve the debris collection capacity of the self-cleaning component 20.

[0218] For example, please refer to Figure 9. During the rotation of the fan blade 272, the gap between the guide surface 25112 and the fan blade 272 remains consistent. During the process of the fan blade 272 driving the garbage located in the receiving cavity 251 to move along the guide surface 25112 towards the second opening 253, the fan blade 272 and the guide surface 25112 jointly abut against the garbage, so that the garbage moves along the guide surface 25112 under the drive of the fan blade 272.

[0219] For example, please refer to Figure 9. The plane R2 shown in the figure is the tangent plane of the guide surface 25112 on the side of the flywheel 27 away from the first opening 252. The tangent plane R2 intersects with the second opening 253.

[0220] It is understood that the shape of the guide surface 25112 is not limited. For example, the guide surface 25112 is a plane.

[0221] It is understood that the positional relationship between the tangent plane of the guide surface 25112 on the side near the transition cavity 2513 and the second opening 253 is not limited. For example, the tangent plane of the guide surface 25112 on the side near the transition cavity 2513 does not intersect with the second opening 253.

[0222] In one embodiment, referring to FIG9, the flywheel 27 includes a flywheel body 271 and a fan blade 272 connected to the flywheel body 271. The end of the fan blade 272 that is radially away from the flywheel body 271 is in contact with or close to the guide surface 25112.

[0223] For example, the fan blade 272 is attached to the guide surface 25112 at one end that is radially away from the flywheel body 271.

[0224] For example, referring to Figure 9, the distance between the end of the fan blade 272 that is radially away from the flywheel body 271 and the guide surface 25112 can be 0 to 7 mm.

[0225] In this embodiment, the end of the fan blade 272 that is radially away from the flywheel body 271 is in contact with or close to the guide surface 25112, so that the flywheel 27 can disturb the garbage in the receiving cavity 251 as much as possible, so that the garbage can be sucked into the vacuuming device 26 by the suction airflow of the vacuuming device 26, which is beneficial to improving the garbage collection ability of the self-cleaning component 20.

[0226] In one embodiment, please refer to Figures 7-9. The outer casing 25 includes an upper casing 254 and a lower casing 255 that are detachably connected. The upper casing 254 and the lower casing 255 form a receiving cavity 251. The flywheel 27 is rotatably connected to the upper casing 254.

[0227] In this embodiment, the upper housing 254 and the lower housing 255 are detachably connected, and the flywheel 27 is rotatably connected to the upper housing 254, so that when the upper housing 254 is detached from the lower housing 255, the flywheel 27 can also be detached from the upper housing 254 together. This allows the garbage remaining on the lower housing 255 to be directly cleaned when the upper housing 254 is detached from the lower housing 255, making it convenient to clean the self-cleaning component 20.

[0228] It is understood that the connection position between the flywheel 27 and the housing 25 is not limited. For example, the flywheel 27 can also be rotatably connected to the lower housing 255.

[0229] In one embodiment, referring to Figures 7, 8, 12 and 13, the lower housing 255 has a drain outlet 2551 communicating with the receiving cavity 251.

[0230] In this embodiment, during the cleaning process of the cleaning device's cloth on the cleaning tray 100, the wastewater generated by the cleaning cloth flows through the cleaning tray 100 and the lower housing 255 and is discharged through the drain outlet 2551. Some water-soluble or small stains are discharged with the wastewater through the drain outlet 2551, while larger stains flow with the water into the self-cleaning component 20 and remain on the lower housing 255, forming waste after drying. The remaining waste moves towards the second opening 253 under the combined action of the suction airflow of the vacuum device 26 and the flywheel 27 to be collected by the self-cleaning component 20, thus realizing the self-cleaning function of the base station.

[0231] In one embodiment, referring to Figures 7, 8 and 10, the size of the first opening 252 is larger than the size of the second opening 253 along the axial direction of the flywheel 27.

[0232] In this embodiment, along the axial direction of the flywheel 27, the larger first opening 252 allows more debris to enter the receiving cavity 251 first, facilitating the suction airflow of the vacuum cleaner 26 and the flywheel 27 to jointly collect the debris located in the receiving cavity 251. The smaller second opening 253 helps to reduce the size of the vacuum cleaner 26 and also helps the debris to gather at the second opening 253 so that the debris can enter the vacuum cleaner 26 through the second opening 253.

[0233] For example, please refer to Figure 10, where R3 is the dimension of the first opening 252 along the axial direction of the flywheel 27, and R4 is the dimension of the second opening 253 along the axial direction of the flywheel 27. The dimension R3 of the first opening 252 is greater than the dimension R4 of the second opening 253.

[0234] It is understood that the size relationship between the first opening 252 and the second opening 253 along the axial direction of the flywheel 27 is not limited. For example, the size of the first opening 252 along the axial direction of the flywheel 27 may also be less than or equal to the size of the second opening 253.

[0235] In one embodiment, referring to FIG8, along the suction airflow direction of the vacuuming device 26, the size of the receiving cavity 251 in the axial direction of the flywheel 27 gradually decreases from the first opening 252 toward the second opening 253.

[0236] In this embodiment, the size of the receiving cavity 251 along the axial direction of the flywheel 27 gradually decreases from the first opening 252 toward the second opening 253. On the one hand, the larger first opening 252 allows more debris to enter the receiving cavity 251 first, facilitating the collection of debris in the receiving cavity 251 by the suction airflow of the vacuum cleaner 26 and the flywheel 27. The smaller second opening 253 helps to reduce the size of the vacuum cleaner 26 and also facilitates the accumulation of debris at the second opening 253, so that the debris can enter the vacuum cleaner 26 through the second opening 253. On the other hand, the flow rate of the suction airflow of the vacuum cleaner 26 gradually increases, which also facilitates the entry of debris into the vacuum cleaner 26 through the second opening 253.

[0237] In one embodiment, referring to Figures 12 and 13, the cleaning tray 100 includes a cleaning tray body 10 and a scraper disposed on the cleaning tray body 10. The outer shell 25 includes an upper shell 254 and a lower shell 255. The lower shell 255 is disposed on the tray body and has a drain outlet 2551 communicating with the receiving cavity 251. The scraper can scrape off the garbage and sewage on the tray body so that the receiving cavity 251 can accommodate at least part of the garbage and the drain outlet 2551 can discharge sewage.

[0238] In this embodiment, the garbage and sewage on the disk body can gradually gather towards the self-cleaning component 20 under the disturbance of the scraper. The sewage is discharged through the drain port 2551 on the lower housing 255, and the garbage enters the receiving cavity 251 through the first opening 252. Under the combined action of the suction airflow of the vacuuming device 26 and the flywheel 27, it is sucked into the vacuuming device 26 through the second opening 253, which is conducive to realizing the self-cleaning function of the base station.

[0239] In one embodiment, referring to Figures 6 and 7, there are two cleaning trays 100, and the self-cleaning component 20 is disposed across the two cleaning trays 100.

[0240] In this embodiment, the garbage and sewage on the two cleaning disc bodies 10 can gradually converge to the same self-cleaning component 20 under the disturbance of the corresponding scraper. The two cleaning discs 100 share one self-cleaning component 20, which helps to reduce the number of self-cleaning components 20, and thus helps to reduce the production cost of the cleaning system.

[0241] Example 3

[0242] For example, as shown in Figures 14 and 15, the cleaning base station 1000 according to an embodiment of the present invention includes a base station body 200, a sewage tank 250, a sewage pipe 300, and a cleaning tray 100. The cleaning tray 100 includes a cleaning tray body 10 and a self-cleaning component 20. The self-cleaning component 20 includes an air blowing pipe 28.

[0243] Specifically, the cleaning base station 1000 works in conjunction with the cleaning robot. When the cleaning robot's battery is low, it can automatically return to the cleaning base station 1000 to recharge, ensuring that the cleaning robot always has sufficient power without manual intervention, thus improving the continuity and efficiency of cleaning. The cleaning base station 1000 can also have an automatic dust collection function, automatically emptying the dust box when the robot returns to the base station, reducing the hassle of manual cleaning for users. For cleaning robots with mopping functions, the cleaning base station 1000 can also automatically wash the mop cloth, maintaining its cleanliness and improving mopping performance.

[0244] In addition, the cleaned cloths are dried with hot air inside the cleaning base station 1000 to prevent bacterial growth and keep the cloths dry and hygienic.

[0245] Furthermore, as shown in Figures 14 and 16, the lower end of the base station body 200 is provided with a receiving cavity 210, in which the cleaning robot is adapted to be placed, realizing the cooperation between the cleaning base station 1000 and the cleaning robot. The bottom wall of the receiving cavity 210 is provided with a sewage tank 110, in which the sewage after washing the cleaning robot's rag enters the sewage tank 110. The sewage tank 250 is located inside the base station body 200 and can hold the remaining sewage after washing the cleaning robot's rag. Users can treat the sewage in the sewage tank 250, which facilitates the treatment of sewage from the cleaning base station 1000 and greatly improves the convenience of users using the cleaning robot.

[0246] Furthermore, as shown in Figures 15 and 16, the sewage pipe 300 is located in the receiving cavity 210. The lower end of the sewage pipe 300 is provided with a sewage inlet 310. The lower end of the sewage pipe 300 extends into the sewage tank 110 to guide the sewage in the sewage tank 110 into the sewage tank 250. After mopping the floor, the rag is returned to the cleaning base station 1000 for cleaning. After each cleaning, some mud and sand will remain in the sewage tank 110. When the sewage pipe 300 guides the sewage in the sewage tank 110 into the sewage tank 250, some of the mud and sand in the sewage tank 110 will enter the sewage pipe 300 along with the water flow and be pumped into the sewage tank 250.

[0247] In addition, when the cleaning base station 1000 has an automatic water supply and drainage function, the sewage in the cleaning base station 1000 can be automatically discharged into the sewer, and the user does not need to deal with the sewage tank 250, which increases the user's convenience.

[0248] In existing technologies, when the sewage pipe is about to finish pumping water, the water flow will be reduced or even intermittent. This sediment will settle at the sewage inlet. Over time, the sediment at the sewage inlet will accumulate more and more, eventually blocking the sewage inlet, causing the sewage pipe to be unable to pump sewage, and triggering a malfunction of the cleaning base station.

[0249] As shown in Figures 15 and 16, the lower end of the air blowing pipe 28 extends into the sewage tank 110 and is provided with an air blowing port 281. The air blowing port 281 is adjacent to the sewage inlet 310. When the sewage pipe 300 guides the sewage in the sewage tank 110 into the sewage tank 250, the air blowing port 281 continuously blows air towards the sewage inlet 310, so that the mud and sand at the sewage inlet 310 cannot accumulate, preventing the sewage inlet 310 from being blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0250] According to the embodiment of the present utility model, the cleaning base station 1000 is equipped with a sewage pipe 300 and an air blowing pipe 28. The lower end of the air blowing pipe 28 extends into the sewage tank 110 and is provided with an air blowing port 281. The air blowing port 281 is adjacent to the sewage inlet 310 at the lower end of the sewage pipe 300. When the sewage pipe 300 guides the sewage in the sewage tank 110 to the sewage tank 250 in the base station body 200, the air blowing port 281 continuously blows air towards the sewage inlet 310, so that the mud and sand at the sewage inlet 310 cannot accumulate, preventing the sewage inlet 310 from being blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0251] In some embodiments of this utility model, such as those shown in Figures 18 and 19, the air blowing port 281 is positioned towards the sewage inlet 310, so that the airflow in the air blowing pipe 28 can be accurately directed towards the sewage inlet 310, preventing the accumulation of mud and sand at the sewage inlet 310, preventing the sewage inlet 310 from becoming blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0252] In some embodiments of this utility model, as shown in Figures 18 and 19, the lower end of the air blowing pipe 28 has a bottom wall for sealing the open end of the lower end of the air blowing pipe 28. The end of the bottom wall near the sewage pipe 300 has a first notch 2811, and the lower end of the peripheral wall of the air blowing pipe 28 near the sewage pipe 300 has a second notch 2812. The first notch 2811 and the second notch 2812 are connected to form an air blowing port 281, so that airflow outlets are provided on both the bottom wall and the peripheral wall of the air blowing pipe 28 facing the sewage inlet 310, so that the airflow in the air blowing pipe 28 can be sprayed towards the sewage inlet 310 more accurately, so that the mud and sand at the sewage inlet 310 cannot accumulate, preventing the sewage inlet 310 from being blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0253] In some embodiments of this utility model, such as those shown in Figures 18 and 19, the air blowing port 281 is located below the sewage inlet 310 along the vertical direction (e.g., the vertical direction shown in Figure 5). The air blowing port 281 can blow the mud and sand at the sewage inlet 310 toward the outside of the sewage pipe 300, so as to avoid the mud and sand from clogging the sewage pipe 300 and avoid the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0254] In some embodiments of this utility model, such as shown in Figure 14, the cleaning base station 1000 further includes an air pump 400, which is located inside the base station body 200. The air pump 400's suction port 410 is connected to the sewage tank 250, and its outlet 420 is connected to the air blowing pipe 28. The air pump 400 draws air from the sewage tank 250, creating a negative pressure inside the sewage tank 250. The sewage pipe 300, connected to the sewage tank 250, draws sewage from the sewage tank 110. The airflow blown from the air pump 400's outlet 420 is used to spray airflow towards the sewage inlet 310, preventing the accumulation of mud and sand at the sewage inlet 310, thus preventing blockage of the sewage inlet 310 and avoiding malfunctions of the cleaning base station 1000 caused by the sewage pipe 300's inability to draw sewage. The air pump 400, which is built into the cleaning base station 1000 to provide negative pressure to the sewage tank 250, can be used to provide airflow to the air blowing pipe 28 without increasing the additional manufacturing cost of the cleaning base station 1000.

[0255] In some embodiments of this utility model, such as those shown in Figures 14 and 22, the cleaning base station 1000 further includes an adapter 150. The adapter 150 has a first channel 151 and a second channel 152. One end of the first channel 151 is connected to the end of the sewage pipe 300 opposite to the sewage inlet 310, and the other end is connected to the sewage tank 250 via a first pipe 11511. One end of the second channel 152 is connected to the end of the air blowing pipe 28 opposite to the air blowing port 281, and the other end is connected to the air outlet 420 of the air pump 400 via a second pipe 1521. By providing the adapter 150, the connection direction between the air blowing pipe 28 and the air pump 400, and the connection direction between the sewage pipe 300 and the sewage tank 250, can be changed according to the internal layout of the cleaning base station 1000, thereby increasing the full utilization of the internal space of the cleaning base station 1000.

[0256] For example, the sewage pipe 300 includes a first pipe section and a second pipe section. The first pipe section extends vertically and its upper end connects to the second pipe section. The second pipe section extends horizontally (e.g., the horizontal direction shown in Figure 18). The layout of the sewage pipe 300 is relatively reasonable. The air blowing pipe 28 includes a third pipe section and a fourth pipe section. The third pipe section extends vertically and its upper end connects to the fourth pipe section. The fourth pipe section extends horizontally. The layout of the sewage pipe 300 is relatively reasonable. The first channel 151 of the adapter 150 reverses the horizontal direction of the second pipe section to the vertical direction, facilitating connection with the sewage tank 250. The second channel 152 of the adapter 150 reverses the horizontal direction of the fourth pipe section to the vertical direction, facilitating connection with the water pump 240.

[0257] Furthermore, as shown in Figure 21, the cleaning base station 1000 also includes a first sealing element 260 and a second sealing element 261. The first sealing element 260 is located at the connection position between the end of the sewage pipe 300 away from the sewage inlet 310 and the first channel 151. The first sealing element 260 can seal the sewage pipe 300 and the first channel 151, ensuring the sewage suction effect of the sewage pipe 300. The second sealing element 261 is located at the connection position between the end of the air blowing pipe 28 away from the air blowing port 281 and the second channel 152. The second sealing element 261 can seal the air blowing pipe 28 and the second channel 152, ensuring the air blowing effect of the air blowing pipe 28.

[0258] Furthermore, as shown in Figure 21, the first seal 260 and the second seal 261 are integrated into one piece, which reduces the manufacturing cost of the first seal 260 and the second seal 261 and improves the overall sealing effect of the first seal 260 and the second seal 261.

[0259] In some embodiments of this utility model, such as those shown in Figures 18 and 19, the cleaning base station 1000 further includes a connector 270, which is fixedly connected to the bottom wall of the receiving cavity 210. The sewage pipe 300 and the air blowing pipe 28 are fixedly mounted on the connector 270, so that the sewage pipe 300 and the air blowing pipe 28 are fixedly connected to the connector 270 and then fixedly connected to the bottom wall of the receiving cavity 210, which facilitates the assembly of the cleaning base station 1000.

[0260] For example, the sewage pipe 300, the air blowing pipe 28 and the connector 270 are integrated plastic parts, and the integrated sewage pipe 300, the air blowing pipe 28 and the connector 270 are directly fixedly connected to the bottom wall of the receiving cavity 210, which facilitates the assembly of the cleaning base station 1000.

[0261] In some embodiments of this utility model, such as those shown in Figures 17 and 20, the cleaning base station 1000 further includes a filter 280, which is disposed above the wastewater tank 110 and has a plurality of second filter holes 2801. Wastewater from cleaning the cleaning robot's rags enters the wastewater tank 110 and is filtered by the filter 280. The second filter holes 2801 can filter out hair and larger particles in the wastewater, reducing the risk of clogging the wastewater pipe 300.

[0262] In some embodiments of this utility model, the diameter d of the second filter hole 2801 satisfies: 1mm ≤ d ≤ 3mm. It is understood that the diameter d of the second filter hole 2801 can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, or 3mm. A diameter d of not less than 1mm ensures the water flow effect of the filter 280 and prevents sewage from clogging the top of the filter 280; a diameter d of not more than 3mm ensures the filtration effect of the filter 280, prevents large particles from entering the sewage tank 110, and reduces the risk of clogging the sewage pipe 300.

[0263] In some embodiments of this utility model, as shown in Figures 15 and 17, a cleaning tank 120 is provided on the bottom wall of the receiving cavity 210. The cleaning tank 120 is connected to the sewage tank 110. A cleaning boss 130 is provided on the bottom wall of the cleaning tank 120. The free end face of the cleaning boss 130 is provided with multiple clean water outlets 140 for cleaning the cleaning robot's cloth. The sewage in the cleaning tank 120 enters the sewage tank 110 through the filter 280. The cleaning boss 130 rubs against the cloth, which can clean the cloth, avoiding the need for the user to manually clean the cloth and improving the user experience.

[0264] In some embodiments of this utility model, such as shown in Figure 14, the cleaning base station 1000 further includes a clean water tank 220, a solenoid valve 230, and a water pump 240. The clean water tank 220 is used to hold clean water. The clean water coming out of the clean water tank 220 is divided into two paths through the solenoid valve 230. The first path goes to the water pump 240, and the second path goes to the water inlet of the cleaning robot. The cleaning tank 120 is divided into two along the left and right direction (for example, the left and right direction shown in Figure 4). The clean water coming out of the water pump 240 is divided into two paths to the clean water outlets 140 of the left and right cleaning tanks 120, so as to clean the rag.

[0265] In some embodiments of this utility model, as shown in FIG16, the cleaning base station 1000 further includes an entrance ramp 160. In the direction from front to back, the upper surface of the entrance ramp 160 is inclined from the ground toward the bottom wall of the receiving cavity 210, so as to facilitate the cleaning robot to enter the receiving cavity 210 of the cleaning base station 1000.

[0266] The following description, with reference to the accompanying drawings, describes a specific embodiment of a clean base station 1000 according to the present invention. It is to be understood that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0267] The cleaning device according to an embodiment of the present invention, as shown in Figures 14-17, includes a base station body 200, a sewage tank 250, a sewage pipe 300, an air blowing pipe 28, an air pump 400, an adapter 150, a first seal 260, a second seal 261, a connector 270, and a filter 280.

[0268] Specifically, the cleaning base station 1000 works in conjunction with the cleaning robot. When the cleaning robot's battery is low, it can automatically return to the cleaning base station 1000 to recharge, ensuring that the cleaning robot always has sufficient power without manual intervention, thus improving the continuity and efficiency of cleaning. The cleaning base station 1000 can also have an automatic dust collection function, automatically emptying the dust box when the robot returns to the base station, reducing the hassle of manual cleaning for users. For cleaning robots with mopping functions, the cleaning base station 1000 can also automatically wash the mop cloth, maintaining its cleanliness and improving mopping performance.

[0269] In addition, the cleaned cloths are dried with hot air inside the cleaning base station 1000 to prevent bacterial growth and keep the cloths dry and hygienic.

[0270] The lower end of the base station body 200 is provided with a receiving cavity 210, in which a cleaning robot is adapted to be placed. A wastewater tank 110 is provided on the bottom wall of the receiving cavity 210, and a filter 280 is located above the wastewater tank 110. The filter 280 has multiple second filter holes 2801. Wastewater from cleaning the cleaning robot's cloth enters the wastewater tank 110 and is filtered by the filter 280. The second filter holes 2801 can filter out hair and larger particles in the wastewater, reducing the risk of clogging the wastewater pipe 300. A cleaning tank 120 is provided on the bottom wall of the receiving cavity 210, and the cleaning tank 120 is connected to the wastewater tank 110. A cleaning boss 130 is provided on the bottom wall of the cleaning tank 120, and multiple clean water outlets 140 are provided on the free end face of the cleaning boss 130 for cleaning the cleaning robot's cloth. Wastewater in the cleaning tank 120 passes through the filter 280 and enters the wastewater tank 110. The cleaning protrusion 130 rubs against the cloth to clean it, avoiding the need for manual cleaning and improving the user experience.

[0271] The sewage tank 250 is located inside the base station body 200, and the sewage pipe 300 is located inside the receiving cavity 210. The lower end of the sewage pipe 300 is provided with a sewage inlet 310, and the lower end of the sewage pipe 300 extends into the sewage tank 110 to guide the sewage in the sewage tank 110 into the sewage tank 250. Some of the mud and sand in the sewage tank 110 will enter the sewage pipe 300 along with the water flow and be pumped into the sewage tank 250.

[0272] The lower end of the air blowing pipe 28 extends into the sewage tank 110 and is provided with an air blowing port 281. The air blowing port 281 is adjacent to the sewage inlet 310 and is oriented towards the sewage inlet 310. The lower end of the air blowing pipe 28 has a bottom wall for sealing the open end of the lower end of the air blowing pipe 28. The end of the bottom wall near the sewage pipe 300 has a first notch 2811, and the lower end of the peripheral wall of the air blowing pipe 28 near the sewage pipe 300 has a second notch 2812. The first notch 2811 and the second notch 2812 are connected to form the air blowing port 281, so that airflow outlets are provided on both the bottom wall and the peripheral wall of the air blowing pipe 28 facing the sewage inlet 310. This allows the airflow in the air blowing pipe 28 to be sprayed more accurately towards the sewage inlet 310, preventing the accumulation of mud and sand at the sewage inlet 310, preventing the sewage inlet 310 from becoming blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage. Along the vertical direction, the air blowing port 281 is located below the sewage inlet 310. The air blowing port 281 can blow the mud and sand at the sewage inlet 310 toward the outside of the sewage pipe 300, so that the mud and sand at the sewage inlet 310 cannot accumulate, prevent the sewage inlet 310 from being blocked, avoid the mud and sand from being blocked in the sewage pipe 300, and avoid the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0273] An air pump 400 is installed inside the base station body 200. The air pump 400's intake port 410 is connected to the sewage tank 250, and its outlet port 420 is connected to the air blowing pipe 28. The air pump 400 draws air from the sewage tank 250, creating a negative pressure within it. The sewage pipe 300, connected to the sewage tank 250, then draws sewage from the sewage trough 110. The airflow from the air pump 400's outlet port 420 is directed towards the sewage inlet 310, preventing the accumulation of sediment and clogging of the inlet, thus avoiding malfunctions in the cleaning base station 1000 caused by the sewage pipe 300's inability to draw sewage. The air pump 400, which provides negative pressure to the sewage tank 250, can be used within the cleaning base station 1000 itself to provide airflow to the air blowing pipe 28, eliminating the need for additional manufacturing costs for the cleaning base station 1000.

[0274] The adapter 150 has a first channel 151 and a second channel 152. One end of the first channel 151 is connected to the end of the sewage pipe 300 away from the sewage inlet 310, and the other end is connected to the sewage tank 250 through the first pipe 11511. One end of the second channel 152 is connected to the end of the air blowing pipe 28 away from the air blowing port 281, and the other end is connected to the air outlet 420 of the air pump 400 through the second pipe 1521. The sewage pipe 300 includes a first pipe section and a second pipe section. The first pipe section extends vertically and its upper end is connected to the second pipe section. The second pipe section extends horizontally. The layout of the sewage pipe 300 is relatively reasonable. The air blowing pipe 28 includes a third pipe section and a fourth pipe section. The third pipe section extends vertically and its upper end is connected to the fourth pipe section. The fourth pipe section extends horizontally. The layout of the sewage pipe 300 is relatively reasonable. The first channel 151 of the adapter 150 changes the front-to-back direction of the second pipe section to the up-and-down direction, facilitating connection with the sewage tank 250; the second channel 152 of the adapter 150 changes the front-to-back direction of the fourth pipe section to the up-and-down direction, facilitating connection with the water pump 240.

[0275] The first seal 260 is located at the connection point between the sewage pipe 300 and the first channel 151 at the end opposite to the sewage inlet 310. The first seal 260 seals the sewage pipe 300 and the first channel 151, ensuring the sewage pipe 300's sewage suction effect. The second seal 261 is located at the connection point between the air blowing pipe 28 and the second channel 152 at the end opposite to the air blowing port 281. The second seal 261 seals the air blowing pipe 28 and the second channel 152, ensuring the air blowing effect of the air blowing pipe 28. The first seal 260 and the second seal 261 are integrated, resulting in lower manufacturing costs and better overall sealing performance.

[0276] The connector 270 is fixedly connected to the bottom wall of the receiving cavity 210. The sewage pipe 300 and the air blowing pipe 28 are fixed on the connector 270. The sewage pipe 300, the air blowing pipe 28 and the connector 270 are a plastic integral part. The integral part of the sewage pipe 300, the air blowing pipe 28 and the connector 270 is directly fixedly connected to the bottom wall of the receiving cavity 210, which facilitates the assembly of the clean base station 1000.

[0277] The dust collection system according to the present utility model includes the cleaning base station 1000 and the cleaning robot described above. The cleaning base station 1000 has a receiving cavity 210. The cleaning robot is detachably disposed in the receiving cavity 210. When the cleaning robot is working, it leaves the cleaning base station 1000 and when the cleaning robot finishes working, it enters the cleaning base station 1000.

[0278] According to the dust collection system of this utility model embodiment, a sewage pipe 300 and an air blowing pipe 28 are installed in the cleaning base station 1000. The lower end of the air blowing pipe 28 extends into the sewage tank 110 and is provided with an air blowing port 281. The air blowing port 281 is adjacent to the sewage inlet 310 at the lower end of the sewage pipe 300. When the sewage pipe 300 guides the sewage in the sewage tank 110 to the sewage tank 250 in the base station body 200, the air blowing port 281 continuously blows air towards the sewage inlet 310, so that the mud and sand at the sewage inlet 310 cannot accumulate, preventing the sewage inlet 310 from being blocked, and avoiding the failure of the cleaning base station 1000 caused by the sewage pipe 300 being unable to pump sewage.

[0279] The cleaning base station 1000 and other components and operations of the dust collection system having the present invention are known to those skilled in the art and will not be described in detail here.

[0280] Example 4

[0281] This application provides a cleaning base station 1000. The cleaning base station 1000 is used to interface with cleaning equipment (not shown in the figure). The cleaning base station 1000 can provide the cleaning equipment with at least charging, cleaning, drying, and sterilization functions. The cleaning equipment can be a mop, a sweeper, a combined mop and sweeper, or a vacuum cleaner, etc.

[0282] Referring to Figures 23-33, the cleaning base station 1000 includes a base station body 200, a cleaning tray 100, and a self-cleaning component 20. The cleaning tray 100 is disposed within the base station body 200. The cleaning tray 100 is used to accommodate a mopping component (not shown in the figures) at the bottom of the cleaning equipment. The mopping component can be, but is not limited to, a mop, a roller brush, or a side brush. The self-cleaning component 20 includes a self-cleaning element 29, a self-cleaning pipe 2100, and a self-cleaning drive component (not shown in the figures). The self-cleaning element 29 includes cleaning blades 292. The cleaning blades 292 are rotatably mounted on the base station body 200; simultaneously, the cleaning blades 292 are located at the air inlet 2110 of the self-cleaning pipe 2100. When the cleaning blades 292 rotate, they can push at least a portion of debris and other contaminants from the upper surface of the cleaning tray 100 into the self-cleaning pipe 2100. The self-cleaning pipe 2100 provides a transport path for the debris and other contaminants. When the self-cleaning drive component is working, it can generate a certain negative pressure. The self-cleaning drive unit is connected to the self-cleaning pipe 2100 to create a negative pressure area within the self-cleaning pipe 2100, thereby driving the cleaning blade 292 to rotate at high speed. When the cleaning blade 292 rotates at high speed, a negative pressure area is formed in the area of ​​the cleaning disc 100 near the self-cleaning unit 29, and at least some of the debris is drawn into the self-cleaning pipe 2100.

[0283] The self-cleaning drive unit generates negative pressure and drives the cleaning blades 292 to rotate, drawing debris and other contaminants from the cleaning tray 100 into the self-cleaning pipe 2100. The negative pressure generated by the self-cleaning drive unit not only causes the cleaning blades 292 to rotate at high speed, effectively cleaning stubborn debris from the cleaning tray 100, but also facilitates the removal of stubborn debris from the cleaning tray 100, allowing it to be quickly drawn into the self-cleaning pipe 2100. Thus, through the combined action of the cleaning blades 292, the self-cleaning pipe 2100, and the self-cleaning drive unit, the accumulated debris on the cleaning tray 100 can be self-cleaned without manual cleaning, thereby improving the user experience.

[0284] The aforementioned self-cleaning duct 2100 can be entirely housed within the base station body 200, with the air outlet 2120 of the self-cleaning duct 2100 located within the base station body 200. Alternatively, at least a portion of the self-cleaning duct 2100 can be housed within the base station body 200, and at least another portion can be located outside the base station body 200, with the air outlet 2120 of the self-cleaning duct 2100 located outside the base station body 200. The air outlet 2120 of the self-cleaning duct 2100 can be connected to a dust collection component (not shown in the figure) in the cleaning base station 1000 or to a separate self-cleaning collection component (not shown in the figure). The dust collection component can be any of the components in the dust collection assembly 500 mentioned below. The self-cleaning collection component can be, but is not limited to, a self-cleaning filter bag or a self-cleaning filter box. The location of the self-cleaning collection component can be related to the location of the air outlet 2120 of the self-cleaning duct 2100.

[0285] The aforementioned self-cleaning drive component can be installed inside the base station body 200. Alternatively, the self-cleaning drive component can be installed outside the base station body. The installation position of the self-cleaning drive component can be related to the installation position of the air outlet 2120 of the self-cleaning duct 2100. The self-cleaning drive component can be, but is not limited to, a self-cleaning drive motor, a self-cleaning drive fan, etc.

[0286] In some embodiments, the self-cleaning component 29 includes a self-cleaning roller 291 and at least one set of cleaning blades. The self-cleaning roller 291 is disposed within the base station body 200. At least one set of cleaning blades is arranged along the long axis of the self-cleaning roller 291. Each set of cleaning blades includes at least one of the aforementioned cleaning blades 292. The self-cleaning roller 291 may be fixedly or detachably connected to the base station body 200. In one embodiment, the self-cleaning roller 291 is not rotating, while the cleaning blades 292 rotate under the action of a self-cleaning drive. Alternatively, the self-cleaning roller 291 is rotatably disposed within the base station body 200, wherein as the self-cleaning roller 291 rotates, the cleaning blades 292 rotate with the self-cleaning roller 291.

[0287] The self-cleaning component 29 may include, but is not limited to, one set of cleaning blades, two sets of cleaning blades, three sets of cleaning blades, or four or more sets of cleaning blades. For example, when the self-cleaning component 29 includes two sets of cleaning blades, the two sets of cleaning blades are arranged along the long axis of the self-cleaning roller 291, as in this embodiment. When the self-cleaning component 29 includes three sets of cleaning blades, the three sets of cleaning blades are arranged along the long axis of the self-cleaning roller 291.

[0288] Cleaning blades 292 are disposed on the outer periphery of the self-cleaning roller 291. The cleaning blades 292 are detachably connected to the outer periphery of the self-cleaning roller 291, such as by snap-fit ​​or plug-in connection. Alternatively, the cleaning blades 292 are fixedly connected to the outer periphery of the self-cleaning roller 291, such as by being integrally formed on the outer periphery of the self-cleaning roller 291. Alternatively, the cleaning blades 292 are rotatably disposed on the outer periphery of the self-cleaning roller 291. When multiple cleaning blades 292 are included, the self-cleaning component 29 may include a rotating sleeve (not shown in the figure), with multiple cleaning blades 292 disposed on the rotating sleeve, which is fitted and rotatably connected to the self-cleaning roller 291. Each group of cleaning blades may include, but is not limited to, one, two, three, four, or more cleaning blades 292. When the number of cleaning blades 292 is multiple, the multiple cleaning blades 292 are disposed at equal or non-equal angles on the outer periphery of the self-cleaning roller 291. As in this embodiment, each group of cleaning blades includes three cleaning blades 292. Under the combined action of the self-cleaning roller 291 and at least one set of cleaning blades, the negative pressure generated by the self-cleaning drive can cause the self-cleaning roller 291 and the cleaning blades 292 on it to rotate at high speed, which is used to clean the garbage in the cleaning disc 100.

[0289] In some embodiments, the self-cleaning component 29 includes at least two sets of cleaning blades. The at least two sets of cleaning blades are arranged along the long axis of the self-cleaning roller 291. Increasing the number of cleaning blade sets can reduce the operating noise of the self-cleaning component 20 and improve the user experience. For example, the operating noise of a self-cleaning component 20 with two sets of cleaning blades is lower than that of a self-cleaning component 20 with one set of cleaning blades.

[0290] Specifically, the orthographic projection of at least one cleaning blade 292 in a set of cleaning blades lies between the orthographic projections of the planes containing two adjacent cleaning blades 292 in an adjacent set of cleaning blades. The cleaning blades 292 in adjacent sets are staggered, reducing the angle between them. This arrangement of the cleaning blades 292 improves wind energy utilization, allowing the self-cleaning component 29 to rotate at high speed, thus increasing the self-cleaning efficiency of debris on the cleaning disc 100. Simultaneously, this arrangement also reduces noise and enhances the user experience. Furthermore, this arrangement ensures that at least one set of cleaning blades receives a greater wind force when the self-cleaning component 29 is in any initial position, reducing dead zones and facilitating rotation of the cleaning blades 292. At the same time, this arrangement also avoids large debris, reducing the risk of large debris clogging the air inlet 2110 of the self-cleaning duct 2100.

[0291] In this embodiment, the self-cleaning component 29 includes two sets of cleaning blades. Each set of cleaning blades includes three cleaning blades 292. The three cleaning blades 292 in one set and the three cleaning blades 292 in the other set are staggered along the length of the self-cleaning roller 291. For example, one set of cleaning blades includes a first blade (not shown in the figure), a second blade (not shown in the figure), and a third blade (not shown in the figure). The other set of cleaning blades includes a fourth blade (not shown in the figure), a fifth blade (not shown in the figure), and a sixth blade (not shown in the figure). The orthographic projection of the first blade along the plane perpendicular to the length of the self-cleaning roller 291 lies between the orthographic projections of the planes containing the fourth and fifth blades. The orthographic projection of the second blade along the plane perpendicular to the length of the self-cleaning roller 291 lies between the orthographic projections of the planes containing the fifth and sixth blades. The orthographic projection of the third blade along the plane perpendicular to the length of the self-cleaning roller 291 lies between the orthographic projections of the planes containing the fourth and sixth blades.

[0292] At least one cleaning blade 292 in the aforementioned set of cleaning blades has its orthographic projection along a plane perpendicular to the length of the self-cleaning roller 291 located between the orthographic projections of two adjacent cleaning blades 292 in an adjacent set of cleaning blades. In this case, the spacing between the cleaning blade 292 and its two adjacent cleaning blades may be the same or different. For example, the spacing between the orthographic projection of the first blade along the length of the self-cleaning roller 291 and the orthographic projections of the fourth and fifth blades may be the same or different. In this embodiment, the orthographic projection of the first blade along the length of the self-cleaning roller 291 lies on the bisector of the orthographic projections of the fourth and fifth blades. The three cleaning blades 292 in each set of cleaning blades are equiangularly distributed around the outer periphery of the self-cleaning roller 291.

[0293] In some embodiments, the cleaning blade 292 may be, but is not limited to, plate-shaped or arc-shaped. In this embodiment, the cleaning blade 292 is arc-shaped. When the cleaning blade 292 moves on the upper surface of the cleaning tray 100, the recess of the cleaning blade 292 may face towards the interior of the self-cleaning pipe 2100, facilitating the pushing of debris into the self-cleaning pipe 2100. Alternatively, when the cleaning blade 292 moves to the surface of the cleaning tray 100 in the self-cleaning member 29, the recess of the cleaning blade 292 may also face away from the interior of the self-cleaning pipe 2100.

[0294] Specifically, the cleaning blade 292 includes a first blade end (not shown in the figure) and a second blade end (not shown in the figure) disposed opposite to each other. The first blade end is connected to the outer periphery of the self-cleaning roller 291. The second blade end is away from the self-cleaning roller 291. The length extension direction of the second blade end is the same as the extension direction of the self-cleaning roller 291. When the cleaning blade 292 rotates, the vertical distance between any position of the second blade end and the surface of the cleaning tray 100 is the same. The length extension direction of the first blade end can be the same as the length direction of the self-cleaning roller 291. Alternatively, the length extension direction of the first blade end can be inclined to the length direction of the self-cleaning roller 291. When the length extension direction of the first blade end is inclined to the length direction of the self-cleaning roller 291, it can be ensured that the length extension direction of the second blade end is the same as the extension direction of the self-cleaning roller 291.

[0295] In some embodiments, the cleaning blade 292 is made of a flexible material. By limiting the cleaning blade 292 to a flexible material, not only can the hard contact between the cleaning blade 292 and the surface of the cleaning disc 100 or debris be reduced, thus reducing noise and improving the user experience, but the cleaning efficiency of the self-cleaning component 20 in cleaning debris can also be improved. The flexible material can be, but is not limited to, rubber, plastic, etc.

[0296] In some embodiments, the self-cleaning component 20 includes a first housing 2200 and a second housing 2300. The first housing 2200 and the second housing 2300 are connected. The connection method can be detachable or fixed. Detachable connection can be, but is not limited to, snap-fit, plug-in, and bolts. As in this embodiment, the first housing 2200 and the second housing 2300 are snap-fit ​​connected. Alternatively, the first housing 2200 and the second housing 2300 are fixedly connected. Fixed connection can be, but is not limited to, welding, integral molding, etc.

[0297] The self-cleaning duct 2100 is formed between the first housing 2200 and the second housing 2300. The self-cleaning duct 2100 has a self-cleaning cavity 2130. The self-cleaning cavity 2130 provides a space for the self-cleaning component 29. The self-cleaning component 29 is located within the self-cleaning cavity 2130; simultaneously, the self-cleaning component 29 is rotatable within the first housing 2200. An air inlet 2110 of the self-cleaning duct 2100 is formed between one end of the first housing 2200 and one end of the second housing 2300. An air outlet 2120 of the self-cleaning duct 2100 is formed between the other end of the first housing 2200 and the other end of the second housing 2300. By defining the self-cleaning duct 2100 formed by the first housing 2200 and the second housing 2300, airflow can be guided in, increasing the speed at which air enters the self-cleaning cavity 2130, thereby increasing the rotational speed of the self-cleaning component 29 and improving the self-cleaning efficiency of the self-cleaning assembly 20.

[0298] In addition, the second housing 2300 has a plurality of first filter holes 2310. The second housing 2300 acts as a filter layer (not shown in the figure) and can play a certain filtering role. After the mopping parts in the cleaning device are cleaned in the cleaning tray 100, the debris in the cleaning tray 100 is filtered through the first filter holes 2310. Sewage and debris smaller than the size of the first filter holes 2310 pass through the first filter holes 2310 and are pumped away by the water pumping assembly (not shown in the figure). Debris larger than or equal to the size of the first filter holes 2310 is cleaned by the self-cleaning assembly 20. The shape of the first filter holes 2310 in the second housing 2300 may be, but is not limited to, circular, elliptical, and irregular shapes.

[0299] Specifically, the first housing 2200 is at least partially arc-shaped. The second housing 2300 is at least partially arc-shaped. The arc-shaped portions of the first housing 2200 and the second housing 2300 enclose the aforementioned self-cleaning cavity 2130, meaning that the self-cleaning cavity 2130 has an approximately circular or annular cross-section perpendicular to the length of the self-cleaning roller 291. When the self-cleaning component 29 rotates within the aforementioned self-cleaning cavity 2130, it not only reduces interference and noise, improving the user experience, but also facilitates the rapid introduction of air into the self-cleaning duct 2100, thereby improving the self-cleaning efficiency of the self-cleaning component 20.

[0300] In other embodiments, the self-cleaning component 20 may include a first housing 2200. The cleaning tray 100 may be the second housing 2300 described above. That is, the cleaning tray 100 and the first housing 2200 are arranged to form the self-cleaning channel 2100 described above. The cleaning tray 100 has a plurality of first filter holes 2310, and the cleaning tray 100 also functions as a filter layer. By sharing the same second housing 2300, the self-cleaning component 20 can reduce production costs, etc.

[0301] In some embodiments, the orthographic projection of the air outlet 2120 of the self-cleaning duct 2100 at the end of the self-cleaning duct 2100 away from the self-cleaning component 29 is located within the end of the self-cleaning duct 2100 away from the self-cleaning component 29. Specifically, if the orthographic projection size of the air outlet 2120 at the end of the self-cleaning duct 2100 away from the self-cleaning component 29 is smaller than the size of the end of the self-cleaning duct 2100 away from the self-cleaning component 29, then the air outlet 2120 can be located at the middle of the end of the self-cleaning duct 2100 away from the self-cleaning component 29, or at the left end of the end of the self-cleaning duct 2100 away from the self-cleaning component 29, or at the right end of the end of the self-cleaning duct 2100 away from the self-cleaning component 29. Alternatively, the orthographic projection size of the air outlet 2120 at the end of the self-cleaning duct 2100 away from the self-cleaning component 29 is exactly equal to the size of the end of the self-cleaning duct 2100 away from the self-cleaning component 29. By limiting the air outlet 2120 to the end of the self-cleaning duct 2100 away from the self-cleaning component 29, the noise of the self-cleaning duct 2100 can be reduced, the operating noise of the self-cleaning component 20 can be improved, and the user experience can be enhanced.

[0302] When the orthographic projection size of the air outlet 2120 of the self-cleaning duct 2100 at the end of the self-cleaning duct 2100 away from the self-cleaning component 29 is smaller than the size of the end of the self-cleaning duct 2100 away from the self-cleaning component 29, the connection between the air outlet 2120 of the self-cleaning duct 2100 and the self-cleaning duct 2100 is rounded, further reducing the noise inside the self-cleaning duct 2100.

[0303] In some embodiments, the cleaning base station 1000 includes a dust collection component 500. The dust collection component 500 collects dust and draws debris from the cleaning equipment into itself, automating the cleaning process. The dust collection component 500 includes a dust collection drive (not shown in the figure), a dust collection pipe 510, and a dust collection housing. The end of the dust collection pipe 510 near the dust collection housing is connected to the dust collection housing. The end of the dust collection pipe 510 near the cleaning equipment is connected to the cleaning equipment. The dust collection drive creates a negative pressure. When the cleaning equipment is connected to the cleaning base station 1000, the dust collection drive operates and creates a negative pressure, drawing debris from the cleaning equipment into the dust collection pipe 510 and then into the dust collection housing. Thus, the cleaning base station 1000 can automatically clean debris from the cleaning equipment using the dust collection component 500, eliminating the need for manual cleaning and improving the user experience. The dust collection drive may be, but is not limited to, a dust collection fan or a dust collection motor.

[0304] The dust collection component 500 and the self-cleaning component 20 are provided separately, that is, the structure of the dust collection component 500 and the structure of the self-cleaning component 20 are not shared. Alternatively, the dust collection component 500 and the self-cleaning component 20 are provided in a way that is at least partially shared, that is, the structure of the dust collection component 500 and the structure of the self-cleaning component 20 are at least partially shared.

[0305] In one specific embodiment, the dust collection assembly 500 includes a dust collection drive, a dust collection pipe 510, and a dust collection receiver. The dust collection pipe 510 includes a common pipe 511, a first dust collection section 512, and a second dust collection section 513. The ends of the common pipe 511 are connected to both the first dust collection section 512 and the second dust collection section 513. When the dust collection assembly 500 and the self-cleaning assembly 20 are working, waste and other debris must pass through the common pipe 511. The first dust collection section 512 and the second dust collection section 513 are both used for waste and other debris to enter the common pipe 511. The first dust collection section 512 and the second dust collection section 513 function as waste inlets (not shown in the figure). The first dust collection section 512 is detachably connected to the cleaning equipment, and the second dust collection section 513 is detachably connected to the self-cleaning pipe 2100.

[0306] The cleaning base station 1000 includes a reversing component 600. The reversing component 600 is housed within the dust collection component 500. The reversing component 600 serves a reversing function. When the cleaning base station 1000 operates the dust collection component 500 and the self-cleaning component 20, different states of the reversing component 600 are adjusted to meet both dust collection and self-cleaning requirements. When the dust collection component 500 of the cleaning base station 1000 is operating, the reversing component 600 is in its first state, at which time the first dust collection section 512 is connected to and interacts with the cleaning equipment. Waste and other debris in the cleaning equipment sequentially pass through the first dust collection section 512, the common pipe 511, and the dust collection container. When the self-cleaning component 20 of the cleaning base station 1000 is operating, the reversing component 600 is in its second state, at which time the second dust collection section 513 is connected to and interacts with the self-cleaning pipe 2100. Waste on the cleaning tray 100 sequentially passes through the second dust collection section 513, the common pipe 511, and the dust collection container.

[0307] Meanwhile, the dust collection drive is the self-cleaning drive in the self-cleaning assembly 20 mentioned above. That is, by sharing the drive, production costs can be reduced. Therefore, by changing the structure of the dust collection pipe 510 in the dust collection assembly 500 and adding a second dust collection section 513 to the dust collection pipe 510, the cleaning base station 1000 can switch between different operating conditions of the dust collection assembly 500 and the self-cleaning assembly 20. At the same time, by sharing the same common pipe 511 and the same dust collection drive, production costs can be reduced.

[0308] The aforementioned reversing assembly 600 may include a reversing drive 610 and a reversing segment 620. The reversing drive 610 provides driving force. The reversing segment 620 is disposed at the end of the common conduit 511. The reversing drive 610 drives the reversing segment 620 to rotate, switching the reversing assembly 600 between a first state and a second state. When the reversing assembly 600 is in the first state, the reversing segment 620 closes the second dust collection section 513, and the common conduit 511 and the first dust collection section 512 are connected, with the first dust collection section 512 docking and connecting with the cleaning equipment. When the reversing assembly 600 is in the second state, the reversing segment 620 closes the first dust collection section 512, and the common conduit 511 and the second dust collection section 513 are connected, with the second dust collection section 513 docking and connecting with the self-cleaning conduit 2100. Thus, through the cooperation of the aforementioned commutation drive 610 and commutator 620, the cleaning base station 1000 can automatically switch between two different operating conditions: the dust collection component 500 and the self-cleaning component 20.

[0309] A seal (not shown in the figure) may be provided around the commutator segment 620. When the commutator segment 620 rotates to the first dust collection section 512 or the second dust collection section 513, the commutator segment 620 can be sealed to the first dust collection section 512 or the second dust collection section 513 through the seal, thereby improving the sealing performance between the commutator segment 620 and the first dust collection section 512 or the second dust collection section 513, ensuring that the dust collection assembly 500 and the self-cleaning assembly 20 do not interfere with each other, reducing air leakage, and thus improving the negative pressure stability within the common pipeline 511. The commutator drive component 610 may be, but is not limited to, a commutator motor. The commutator segment 620 may be made of a flexible material. The flexible material may be, but is not limited to, plastic parts, rubber parts, etc.

[0310] In some embodiments, the cleaning tray 100 includes at least two cleaning tanks 120. The two cleaning tanks 120 are connected to each other. Each cleaning tank 120 can be used to accommodate a corresponding mop. During the cleaning process of the mop, debris and other contaminants tend to accumulate on one side of the adjacent area of ​​the two cleaning tanks 120. By placing the self-cleaning component 20 on one side of the adjacent area of ​​the two adjacent cleaning tanks 120, debris and other contaminants on one side of the adjacent area of ​​the two adjacent cleaning tanks 120 can be cleaned, thereby improving the efficiency of debris and other contaminant cleaning. The shape of the cleaning tank 120 may be the same as or different from the shape of the mop. In this embodiment, the shape of the cleaning tank 120 is the same as the shape of the mop, and the size of the cleaning tank 120 is equal to or slightly larger than the size of the mop.

[0311] In some embodiments, the cleaning tray 100 is provided with a boss 700. The boss 700 is detachably or fixedly connected to the cleaning tray 100. As in this embodiment, the boss 700 is integrally formed into the cleaning tray 100. During the cleaning process of the mopping component rotating, debris and other contaminants easily reach one side of the adjacent area of ​​the two cleaning tanks 120; at the same time, the self-cleaning component 20 itself and the mopping component rotate to the aforementioned position. Therefore, the boss 700 is located between one side of the adjacent area of ​​the two cleaning tanks 120 and the self-cleaning component 20, which can reduce the accumulation of debris and other contaminants on one side of the adjacent area of ​​the adjacent cleaning tanks 120, improving the user experience; it also makes it easier for the self-cleaning component 20 to clean up debris and other contaminants.

[0312] Specifically, the boss 700 has a chamfered portion 710 near the end of the self-cleaning component 20. This chamfered portion 710 increases the flow area, reduces flow resistance, and thus reduces noise, thereby improving the user experience. Additionally, the boss 700 includes a first side 720 and a second side 730 arranged adjacent to each other. The first side 720 is arc-shaped and faces one cleaning tank 120. The second side 730 is arc-shaped and faces another cleaning tank 120. When the first side 720 and the second side 730 are arc-shaped, damage to the mopping components can be reduced, thereby lowering operating costs.

[0313] This application provides a cleaning system (not shown in the figure). The cleaning system includes a cleaning base station 1000 and cleaning equipment that cooperates with the cleaning base station 1000. The cleaning base station 1000 can provide the cleaning equipment with at least functions such as charging, cleaning, drying, and sterilization. By using the cleaning base station 1000, the cleaning system can self-clean up accumulated garbage on the cleaning tray 100 without manual cleaning, thereby improving the user experience. It should be noted that the cleaning base station 1000 in this embodiment is the same as the cleaning base station 1000 described in the above embodiments, and will not be repeated here.

[0314] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
