While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being 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 present disclosure to those skilled in the art.

[0040] It is to be understood that the terms used herein are merely for the purpose of describing particular example embodiments and are not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0043] To better meet the needs of household cleaning, cleaning systems with cleaning robots and cleaning bases gradually enter people's families. In addition to charging the cleaning robot, the cleaning base also has the function of cleaning the cleaning parts of the cleaning robot to realize self-cleaning of the cleaning robot.

[0044] When performing self-cleaning of the cleaning robot, the tray of the cleaning base contains a cleaning water body, and the cleaning part is placed in the tray. The self-cleaning of the cleaning part is realized by rotating the cleaning part. However, after cleaning the cleaning part of the robot, the tray will be left with some garbage brought by the cleaning part. The garbage will be deposited in a large area of the tray, which is very inconvenient for the user to clean manually, and the user experience is reduced. Moreover, when there is too much garbage, it will also cause blockage of the water filtering device in the tray, which also needs the user to clean with great effort, further reducing the user experience.

[0045] Therefore, the cleaning tray, the cleaning base station and the cleaning system having the same are provided, which are configured to arrange a scraping assembly in the cleaning tray, scrape the garbage deposited in the cleaning tray by the scraping assembly, and deposit the scraped garbage in a certain area in the cleaning tray, so as to clean the garbage and reduce the possibility of blocking the filter water device.

[0046] The embodiments of the present application will be described below in detail with reference to the accompanying drawings. Figures 1-6 The structure of the cleaning tray provided by the embodiments of the present application will be described.

[0047] The embodiments of the present application will be described below in detail with reference to the accompanying drawings. Figures 1-3 As shown in the drawings, the embodiments provide a cleaning tray 100, which is used for cleaning the cleaning pieces 200 at the bottom of a robot, and the cleaning pieces 200 can be a mop, a cloth, or a structure for sweeping.

[0048] In some examples, the cleaning tray 100 is detachably mounted on the cleaning base station, and the detachable connection modes include clamping, threaded connection, plug-in connection, etc., which will not be enumerated one by one in the embodiments.

[0049] The cleaning tray 100 of the embodiments includes a tray body 10 and a scraping assembly 20, wherein the tray body 10 of the embodiments includes a bottom wall 11 and a side wall 12 connected to the periphery of the bottom wall 11, and the bottom wall 11 and the side wall 12 together enclose a cleaning groove for cleaning the cleaning pieces 200. The shape of the bottom wall 11 and the side wall 12 will not be limited too much in the embodiments, for example, the bottom wall 11 can be approximately circular, elliptical, rectangular, or a combination of the three, which will not be enumerated one by one in the embodiments.

[0050] In some examples, the material of the tray body 10 of the embodiments can be polyethylene, polypropylene, or other materials with certain structural strength, such as metal alloys, which will not be enumerated one by one in the embodiments.

[0051] The scraping assembly 20 of the embodiments is mounted on the bottom wall 11 of the tray body 10, and the number of the scraping assembly 20 can be one or more. For example, when the number of the cleaning pieces 200 is two and both of the cleaning pieces 200 can rotate, the number of the scraping assembly 20 of the embodiments is also two, and the two scraping assemblies 20 and the two cleaning pieces 200 can be arranged one by one in position.

[0052] The scraping assembly 20 of the embodiment comprises a rotating member 21 and a scraping member 22. The material of the rotating member 21 of the embodiment can be plastic such as polyethylene or polypropylene, or metal or other polymer materials with certain structural strength, which are not listed one by one in the embodiment.

[0053] In the embodiment, the rotating member 21 is connected to the bottom wall 11 in a manner of rotating around its own axis, and 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 directly realized by mounting the rotating member 21 on the bottom wall 11, or realized by the support shaft 23 described below. The specific rotating structure is given below.

[0054] The scraping member 22 of the embodiment is fixedly connected to the rotating member 21 and abuts against the bottom wall 11. The rotation of the rotating member 21 drives the scraping member 22 to scrape the bottom wall 11. The action of the scraping member 22 can clean the garbage on the bottom wall 11 of the cleaning tray 100, and the garbage can be scraped to a specific area, for example, an area close to the side wall 12 and away from the water filtering device on the bottom wall 11. When the user cleans the cleaning tray 100, only the specific area needs to be cleaned, which facilitates the user to clean the tray and reduces the possibility of garbage accumulation in the filtering device to cause the filtering device to be blocked, thereby ensuring that the self-cleaning function of the cleaning base station can normally operate.

[0055] In some examples, optionally, the end of the rotating member 21 away from the bottom wall 11 (the upper end in the embodiment) has a mating end face 2111 parallel to the bottom wall 11. Figures 2-4

[0056] In some examples, optionally, the mating end face 2111 can 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 peripheral edge of the platform 211 extends outward from the rotating member 21 in the horizontal direction, so that the radial dimension of the platform 211 in the horizontal direction is greater than that of the remaining part of the rotating member 21 in the horizontal direction. The mating end face 2111 is the upper surface of the platform 211. The shape of the platform 211 can be circular, oval, rectangular or polygonal, which are not listed one by one in the embodiment.

[0057] ​When the matching end face 2111 of the present embodiment is provided with the first friction structure 2112, the first friction structure 2112 can generate frictional limit with the bottom of the cleaning piece 200 placed in the tray, thereby enabling the rotation of the cleaning piece 200 during self-cleaning to drive the rotation of the rotating piece 21 and the scraping piece 22 of the present embodiment, without the need to configure additional power to drive the rotation of the rotating piece 21, which is ingenious in structure and realizes the integrated multi-use of the cleaning piece 200.

[0058] Of course, the rotation drive of the rotating piece 21 of the present embodiment can also be to install a motor or the like driving piece (not shown in the figure) on the bottom wall 11, connect the output shaft of the motor with the rotating piece 21, and use the rotation of the output shaft of the motor to drive the rotation of the rotating piece 21 and the scraping piece 22, but compared with the foregoing mode of configuring the first friction structure 2112, this structure has higher cost and higher structural complexity of the cleaning tray 100 as a whole.

[0059] In addition, a handle or knob structure can also be provided on the matching end face 2111, after the cleaning of the cleaning piece 200 in the cleaning tray 100 is completed, the user holds the handle or holds the knob to drive the rotation of the rotating piece 21 and the scraping piece 22 (not shown in the figure), which does not need to configure a motor or the like driving piece, but needs the user to operate, and can only perform the garbage scraping of the bottom wall 11 of the cleaning tray 100 after the cleaning of the cleaning piece 200, which cannot realize the garbage scraping during the cleaning of the cleaning piece 200, reducing the user experience.

[0060] The structure form of the first friction structure 2112 of the present embodiment has various forms, such as a friction surface with tiny friction particles, a friction surface with pits, etc., and in some examples, the first friction structure 2112 of the present embodiment is a protruding structure provided on the matching end face 2111, which refers to a structure protruding from the matching end face 2111, including protruding points, convex hulls, protruding ribs 21122, etc., which can reduce the possibility of residual cleaning wastewater on the matching end face 2111 compared with recessed structures.

[0061] Further, the convex structure of the embodiment can include a plurality of first convexes 21121, and the cross-sectional shape of the first convex 21121 of the embodiment can be circular in the drawing, or can be rectangular, triangular, or other shapes. The convex height of the first convex 21121 can be between 1 mm and 20 mm, such as 1 mm, 5 mm, 10 mm, 15 mm, and 20 mm. The maximum dimension of the cross section of the first convex 21121 can be 5 mm to 30 mm, such as 5 mm, 15 mm, 20 mm, 25 mm, and 30 mm, and the first convex 21121 can have multiple groups, each group including a plurality of first convexes 21121 arranged at intervals, and the multiple groups of first convexes 21121 are arranged at intervals along the circumferential direction of the mating end surface 2111 of the platform 211, and the distance between the two adjacent groups of first convexes 21121 is much greater than the spacing between the two first convexes 21121 in the same group.

[0062] After the mating end surface 2111 of the platform 211 of the embodiment is in contact with the cleaning member 200, the dirty water during cleaning of the cleaning member 200 can flow out of the space between the protrusions, which can reduce the dirty water remaining in the mating end surface 2111 compared to the friction structure of the recess.

[0063] In some examples, the first friction structure 2112 of the embodiment can include a plurality of convex ribs 21122 arranged at intervals along the circumferential direction of the mating end surface 2111, and the shape of the convex rib 21122 can be a straight line, S-shaped, or L-shaped in the drawing, as long as the plurality of convex ribs 21122 can surround a limiting groove 21123, and one end of the two adjacent convex ribs 21122 surrounds the opening 21124 of the limiting groove 21123, so the specific shape of the convex rib 21122 is not limited in the embodiment.

[0064] Taking the L-shaped convex rib 21122 in the drawing as an example, the number of convex ribs 21122 can be four, and the four convex ribs 21122 are uniformly arranged at intervals along the circumferential direction of the mating end surface 2111, and the two ends of the convex rib 21122 are respectively connected to the outer edge of the mating end surface 2111, so that a water passage is formed between the two adjacent convex ribs 21122, and the space in the middle of the four water passages and the water passage forms the limiting groove 21123, and the four convex ribs 21122 form a cross-shaped limiting groove 21123, which can accommodate at least part of the cleaning member, and matches the shape and size of the cleaning member.

[0065] 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.

[0066] Combined with appendix Figure 4 As shown, 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.

[0067] 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 direction of the scraping arm 221, so as to ensure that the scraping range of the two scraping strips 222 of the two scraping components 20 can cover most of the area of ​​the bottom wall 11 when rotating.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Again, as shown in the accompanying drawings Figure 2 and the accompanying drawings Figure 3 As shown in the accompanying drawings, in some examples, the scraping assembly 20 of the present embodiment further comprises a support shaft 23, and the bottom wall 11 of the cleaning tray 100 of the present embodiment is provided with a mounting groove, the lower end of the support shaft 23 is mounted 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 which is limitedly matched with the mounting groove to improve the stability of the support shaft 23 after installation.

[0073] The rotating member 21 of the present embodiment is coaxially connected with the support shaft 23, and there are two forms for the rotating member 21 and the support shaft 23 of the present embodiment, one is that the support shaft 23 is fixedly connected with the rotating member 21 and rotates synchronously, at this time, a bearing (not shown in the drawings) 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 the rotating member 21 and the scraping member 22 rotate synchronously with the support shaft 23.

[0074] The other is that the rotating member 21 can rotate around the support shaft 23, at this time, the lower end of the support shaft 23 is fixedly installed in the mounting groove, the rotating member 21 is sleeved on the middle and upper part of the support shaft 23 through a bearing, and the rotating member 21 can rotate on the support shaft 23 through the bearing, thereby realizing the synchronous rotation of the rotating member 21 and the scraping member 22.

[0075] Of course, the rotating member 21 of the present embodiment can have other forms in the structure which can rotate around its own axis, for example, the rotating member 21 is directly installed on the bottom wall 11 through a bearing, and the present embodiment does not list them one by one.

[0076] Again, as shown in the accompanying drawings Figure 1 and the accompanying drawings Figure 5 As shown in the accompanying drawings, in some examples, the cleaning tray 100 of the present embodiment further comprises a cleaning plate 30, the cleaning plate 30 can be installed on the bottom wall 11 or the side wall 12, or the cleaning plate 30 is connected with 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, and the present embodiment does not make too many limitations.

[0077] The scraping member 22 of the present embodiment is located between the cleaning plate and the bottom wall 11. The main function of the cleaning plate is to contact the cleaning member 200 when the cleaning member 200 is self-cleaning, and the friction between the cleaning plate and the cleaning member 200 when the cleaning member 200 rotates can improve the cleaning effect of the cleaning member 200. Therefore, the horizontal height of the cleaning plate of the present embodiment can be level or substantially level with the mating end surface 2111 of the platform 211 described above. Therefore, a first through hole 31 needs to be provided on the cleaning plate, which accommodates the end of the rotating member 21 away from the bottom wall 11 (i.e. the platform 211), so that the mating end surface 2111 of the platform 211 can be level or substantially level with the upper surface of the cleaning plate.

[0078] The height of the side wall 12 of the present embodiment should be higher than the height of the cleaning plate. When the cleaning tray 100 of the present embodiment is filled with water, the water body overflows the cleaning plate. Therefore, a second through hole 32 needs to be provided on the cleaning plate. The second through hole 32 has a larger size and a larger number. The second through hole 32 forms a hollow plate structure. The shape of the second through hole 32 can be a fan shape as shown in the figure, and of course it can also be other shapes, such as a circular shape, a triangular shape, etc. This embodiment does not make too many enumerations.

[0079] In some examples, the surface of the cleaning plate 30 away from the bottom wall 11 is provided with a second friction structure 33. The second friction structure 33 generates friction with the cleaning member 200 (such as a cloth) to clean the cleaning member and improve the cleaning efficiency and effect of the cleaning member.

[0080] In some examples, the second friction structure 33 of the present embodiment is also a convex structure, which includes a plurality of second convexes 331 provided on the mating end surface 2111. The second convexes 331 can have multiple rows and multiple columns, and their distribution can be regular or irregular, as long as they can generate sufficient friction with the cleaning member 200 for self-cleaning.

[0081] Of course, the structure of the second friction structure 33 of the present embodiment is not limited to the convex structure. For example, it can also be a pit, or the surface of the cleaning plate 30 can be designed as a rough surface, etc. This embodiment does not make too many descriptions.

[0082] In some examples, the scraping assembly 20 further includes a magnetic member 24 connected to the rotating member 21. The connection between the magnetic member 24 and the rotating member 21 can be welding, bonding, embedding connection, etc. The magnetic member 24 is used to magnetically attract the magnet (not shown in the figure) on the cleaning member 200 of the cleaning system, thereby increasing the connection force between the rotating member 21 and the cleaning member 200, so that the scraping assembly 20 is more easily rotated under the driving of the cleaning member 200.

[0083] The following is an example of the use of the cleaning tray 100 of the present embodiment. Figures 1-6The specific working process of the cleaning tray 100 of the embodiment is described as follows:

[0084] When self-cleaning of the cleaning element 200 (such as a cloth or mop) at the bottom of the cleaning machine body is needed, the cleaning tray 100 is filled with water, and the water level needs to exceed the matching end surface 2111 of the cleaning plate 30 and the top of the rotating element 21. Then, the cleaning element 200 is placed in the tray, a part of the cleaning element 200 is accommodated in the limiting groove 21123 surrounded by the plurality of convex ribs 21122 of the matching end surface 2111, and can generate a certain friction force with the first convex 21121, and the other part of the cleaning element 200 is in contact with the cleaning plate 30.

[0085] When the cleaning element 200 is rotating, it can be self-cleaned by the friction force between itself and the cleaning plate 30, and at the same time, the cleaning element 200 can also drive the rotating element 21 and the scraping element 22 to rotate synchronously, so as to scrape and clean the garbage on the bottom wall 11 of the cleaning tray 100, thereby reducing the possibility of garbage deposition on the bottom wall 11.

[0086] After the self-cleaning process of the cleaning element 200 is completed, the water in the cleaning tray 100 is filtered and recycled by the filtering device, and the rotating element 21 and the scraping element 22 can still be driven to rotate by the rotation of the cleaning element 200 to further scrape the garbage. Finally, the rotation of the cleaning element 200 is stopped. Such cleaning operation can reduce the deposition of garbage on the bottom wall, thereby reducing the possibility of garbage blocking the water filtering device (not shown in the figure) of the cleaning tray 100. Then, the user can clean the scraped garbage accommodated in the arc-shaped groove formed by the arc-shaped scraping element 22 and the bottom wall 11, without cleaning the entire bottom wall 11 of the tray.

[0087] Based on the above cleaning tray 100, the embodiment further provides a cleaning base station, which comprises a base station body (not shown in the figure) and the cleaning tray 100 as described in the above technical solution. The cleaning tray 100 is installed on the base station body, and can be taken out or removed from the base station body, so as to clean the cleaning tray 100 of the embodiment.

[0088] Based on the above cleaning base station, the embodiment further provides a cleaning system, which comprises a cleaning robot (not shown in the figure) and the cleaning base station as described in the above technical solution. The cleaning robot is used to automatically clean the floor of a house, and the cleaning base station is used to charge and self-clean the cleaning robot. The specific structure and cleaning principle of the cleaning robot, and the other structures of the cleaning base station except the cleaning tray 100 are described in the related art, and will not be described herein.

[0089] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any changes or replacements within the technical scope disclosed by the present application, which can be easily thought by those skilled in the art, should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
