[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0045] With the development of intelligent cleaning technology, cleaning robots have entered more and more households, greatly reducing the labor of house cleaning for people, but at the same time, the cleaning robots themselves also need to be cleaned. For this reason, people have proposed a base station that can clean the cleaning robot. After the cleaning robot completes self-cleaning and replenishment, it is necessary to clean the base station again to ensure the cleaning effect of the base station and avoid stains. However, the cleaning parts of the base station in the related art are often relatively raised, which makes it difficult to clean the corner gaps at the raised position of the cleaning parts. In addition, the cleaning parts of the base station in the related art cannot be disassembled, or the disassembly process is relatively cumbersome, which also leads to poor efficiency and effect of self-cleaning of the base station.

[0046] In view of this, see Figure 1-Figure 7 In an embodiment of the first aspect of the utility model, a base station 100 for a cleaning robot 210 is provided. The cleaning robot 210 includes a cleaning component 211 disposed at the bottom thereof. The base station 100 includes a cleaning disc 110 and a scraping member 120 .

[0047] For details, see Figure 1-Figure 2 The cleaning tray 110 is provided with a cleaning tank 111, and the cleaning tank 111 is used to accommodate the cleaning assembly 211. It should be noted that the cleaning tank 111 can be located at any suitable position of the cleaning tank 111, and this application is no longer limited. In addition, the cleaning tank 111 can have an opening, and the direction of the opening is the second direction Y.

[0048] See also Figure 1-Figure 2, the scraper 120 is arranged in the cleaning tank 111 and connected to the cleaning disk 110. In addition, the scraper 120 can be configured to be able to be inserted into the opening. The scraper 120 can have a first surface, and the first surface is suitable for facing the cleaning component 211 along the second direction Y to clean the cleaning component 211. Therefore, the scraper 120 can be any component suitable for cleaning the cleaning component 211, for example, the scraper 120 can be a roller brush, a rubber brush, a hair brush, a cleaning pad, a cleaning cloth, an adsorption device, etc. In addition, the scraper 120 can clean the cleaning component 211 in any manner such as friction, slapping, and adsorption. It can be understood that the first surface of the scraper 120 can be used to clean the cleaning component 211, that is, in different embodiments, the first surface can be the rubber surface of the rubber brush for cleaning, or it can be the outer peripheral wall surface of the roller brush. For the convenience of description, the following is an embodiment in which the scraper 120 is a rubber brush as an illustration, and different embodiments can be combined with each other between different technical solutions.

[0049] In different embodiments, the position of the scraper 120 relative to the opening may vary with the state of the base station 100, that is, the scraper 120 may be located on either side of the opening or pass through the opening. For example, when the cleaning component 211 needs to be cleaned, the scraper 120 may pass through the opening, and when the base station 100 needs to be cleaned, the scraper 120 may be retracted into the opening.

[0050] See also Figure 1-Figure 2 , the scraper 120 and the cleaning tank 111 can move relative to each other so that the upper end of the scraper 120 is close to or away from the bottom of the cleaning tank 111. Specifically, on the one hand, the scraper 120 can be driven to move the first surface to the side where the opening is close to the cleaning component 211, or the cleaning tank 111 can be driven away from the cleaning component 211 so that the first surface is located on the side where the opening is close to the cleaning component 211, thereby starting the step of cleaning the cleaning component 211; on the other hand, the scraper 120 can be driven to move the first surface to the side where the opening is away from the cleaning component 211, or the cleaning tank 111 can be driven close to the cleaning component 211 so that the first surface is located on the side where the opening is away from the cleaning component 211, thereby starting the step of cleaning the cleaning tank 111.

[0051] According to different needs, after the scraper 120 obtains the driving force, it can be located on the side of the opening along the second direction Y close to (or away from) the cleaning component 211 or move to a position coplanar with the bottom of the cleaning tank 111; or, after the cleaning tank 111 obtains the driving force, the opening can be located on the side of the scraper 120 along the second direction Y close to (or away from) the cleaning component 211 or move to a position coplanar with the cleaning tank 111.

[0052] Regarding the way in which the scraper 120 obtains the driving force, in some embodiments, the driving force may be an external thrust applied to the scraper 120 by the user or the cleaning component 211; in other embodiments, a driving device may be provided to provide the driving force to the scraper 120. In some embodiments, the scraper 120 may be connected to a retractable driving member, or the scraper 120 itself may be retractable, or the scraper 120 may be slidably connected to the cleaning tank 111 to achieve the above-mentioned movement of the scraper 120. The way in which the cleaning tank 111 obtains the driving force is similar, and will not be described in detail here.

[0053] According to the combination of the above embodiments, it can be seen that the scraper 120 and the cleaning tank 111 of the utility model can move relative to each other so that the upper end of the scraper 120 is close to or away from the bottom of the cleaning tank 111, so that the base station 100 can cooperate with the cleaning robot 210. When it is necessary to clean the cleaning component 211 of the cleaning robot 210, the scraper 120 can be driven to protrude from the bottom of the cleaning tank 111, that is, the upper end of the scraper 120 is away from the bottom of the cleaning tank 111, and the scraper 120 can be used to clean the cleaning component 211; when it is necessary to clean the cleaning tank 111, the scraper 120 can be driven to retract relative to the bottom of the cleaning tank 111, that is, the upper end of the scraper 120 is close to the bottom of the cleaning tank 111, and the cleaning component 211 can be used to clean the cleaning tank 111, and the scraper 120 will not interfere with the cleaning of the cleaning tank 111, which can make the cleaning effect better. Compared with the prior art, the base station 100 of the utility model allows the scraper 120 to move flexibly relative to the cleaning tank 111, so that the position can be adjusted according to actual needs. When the cleaning component 211 of the cleaning robot 210 needs to be cleaned, the scraper 120 can easily protrude from the bottom of the cleaning tank 111 and stay away from the bottom of the cleaning tank 111, thereby providing sufficient space for the cleaning component 211 of the cleaning robot 210 to clean efficiently; when the cleaning tank 111 needs to be cleaned, the scraper 120 can retract relative to the bottom of the cleaning tank 111 and move closer to the bottom of the cleaning tank 111. At this time, the cleaning component 211 can fully clean the cleaning tank 111 without hindrance. This design not only simplifies the cleaning process of the cleaning tank 111, but also avoids the interference of the scraper 120 with the cleaning component 211 during the cleaning process, thereby improving the cleaning effect of the cleaning component 211 on the base station 100.

[0054] For the embodiment of driving the cleaning tank 111 to move so that the scraping member 120 and the cleaning tank 111 move relative to each other, see Figure 6 and Figure 7In some embodiments, a first movable member 112 is provided on the cleaning disc 110. Specifically, according to different requirements, in some embodiments, the first movable member 112 can be any one of a spring, rubber, silicone, and a telescopic bellows. For ease of description, the following embodiments in which the first movable member 112 is a spring are used as an illustration. Different embodiments can be combined with each other between different technical solutions. The cleaning disc 110 has a bottom surface 113, and the two ends of the first movable member 112 are respectively connected to the bottom surface 113 and the cleaning tank 111. When the cleaning component 211 abuts against the cleaning tank 111, the first movable member 112 is deformed, and the cleaning tank 111 is displaced relative to the scraper 120. Specifically, in some embodiments, the first movable member 112 can be configured to obtain a driving force, and after the driving force is eliminated, the elastic force of the first movable member 112 can drive the cleaning tank 111 to move.

[0055] For the embodiment of driving the scraping member 120 to move so that the scraping member 120 and the cleaning tank 111 move relative to each other, see Figure 3 In some embodiments, a second movable member 114 is provided on the cleaning disk 110, and the cleaning disk 110 has a bottom surface 113. Both ends of the second movable member 114 are respectively connected to the bottom surface 113 and the scraping member 120. When the cleaning component 211 abuts against the scraping member 120, the second movable member 114 is deformed and the scraping member 120 is displaced relative to the cleaning tank 111.

[0056] Regarding the arrangement of the second movable member 114, in other words, the scraping member 120 may also have a second surface. The first surface and the second surface may be arranged relative to each other along the second direction Y. That is to say, along the second direction Y, the second surface is located on the side of the first surface away from the cleaning assembly 211. Based on this, along the second direction Y, one end of the second movable member 114 close to the cleaning assembly 211 may be connected to the second surface, and one end of the second movable member 114 away from the cleaning assembly 211 may be connected to the cleaning tank 111. It is understandable that the above arrangement enables one end of the second movable member 114 along the second direction Y to obtain the driving force from the second surface, and the other end may be supported by the cleaning tank 111, so as to play a better elastic driving role.

[0057] Furthermore, in some embodiments, the first movable member 112 or the second movable member 114 may be an elastic member or a telescopic connecting member.

[0058] For ease of description, an embodiment of driving the scraper 120 to move so that the scraper 120 and the cleaning tank 111 move relative to each other is used as an example for illustration below. Different embodiments may be combined with different technical solutions.

[0059] For the specific configuration of the scraper 120, see Figure 6In some embodiments, the scraping member 120 may include a plurality of ribs 121, and the plurality of ribs 121 may form a mounting groove 122, and the second movable member 114 may be disposed in the mounting groove 122. It is understood that the ribs 121 may be used to clean the cleaning assembly 211, and the ribs 121 may simultaneously define the mounting groove 122 for connecting the second movable member 114. The above arrangement uses the ribs 121 to form the mounting groove 122, which may efficiently utilize space and make the connection between the second movable member 114 and the scraping member 120 more stable.

[0060] In order to enable the scraper 120 and the cleaning tank 111 to move relative to each other, in addition to the first movable member 112 or the second movable member 114, the cleaning tank 111 or the scraper 120 itself can be configured to be elastic to achieve the above relative movement. Specifically, taking the cleaning tank 111 as an example, in some embodiments, the cleaning tank 111 is a first elastic structural member, and when the cleaning component 211 abuts against the bottom of the cleaning tank 111, the bottom of the cleaning tank 111 is deformed, and the cleaning tank 111 is displaced relative to the scraper 120.

[0061] Correspondingly, in other embodiments, the scraper 120 is a second elastic structural member, and when the cleaning assembly 211 abuts against the scraper 120, the scraper 120 is deformed, and the scraper 120 is displaced relative to the cleaning tank 111. More specifically, when the cleaning assembly 211 abuts against the scraper 120, the scraper 120 is deformed in the second direction Y and / or the first direction X.

[0062] In addition, the elastic scraper 120 can also be used to block the opening, see Figure 3 or Figure 5 In some embodiments, the orthographic projection of the scraper 120 on a plane perpendicular to the second direction Y is defined as the first projection, and the orthographic projection of the edge of the opening on a plane perpendicular to the second direction Y is defined as the second projection, so that the first projection can cover the second projection. It can be understood that the above configuration makes the end size of the scraper 120 greater than or equal to the size of the opening. When the scraper 120 is located in the opening, the scraper 120 can be close to the hole wall where the opening is located under the action of its elastic force to prevent the scraper 120 from cleaning the cleaning component 211 or the cleaning component 211 cleaning the scraper 120. When the scraper 120 is cleaning the cleaning component 211 or the cleaning component 211 cleans the scraper 120, the liquid leaks from the gap between the scraper 120 and the opening. Because the scraper 120 is elastic, the scraper 120 can still be inserted into the opening after being acted upon by an external force, and is located on the side of the opening close to the cleaning component 211 along the second direction Y. In addition, a sealing member 117 can also be used to close the opening. Specifically, in some embodiments, a sealing member 117 can be provided between the cleaning tank 111 and the scraper 120. The seal 117 may be a sealing gasket arranged around the opening.

[0063] In addition, in order to make the scraper 120 and the cleaning tank 111 move relative to each other, in addition to the elastic deformation of the first movable member 112 or the second movable member 114, or the deformation of the cleaning tank 111 / scraper 120 itself, the relative movement can also be generated by a power member abutting against the cleaning tank 111 / scraper 120. Specifically, taking the cleaning tank 111 as an example, see Figure 7 In some embodiments, a first power member 115 is further provided on the cleaning disc 110. The cleaning disc 110 has a bottom surface 113. Two ends of the first power member 115 are respectively connected to the bottom surface 113 and the cleaning groove 111. When the first power member 115 pushes the cleaning groove 111, the cleaning groove 111 is displaced relative to the scraping member 120.

[0064] Accordingly, see Figure 1-Figure 2 In other embodiments, a second power member 116 is further provided on the cleaning tray 110. The cleaning tray 110 has a bottom surface 113. Both ends of the second power member 116 are respectively connected to the bottom surface 113 and the scraping member 120. When the second power member 116 pushes the scraping member 120, the scraping member 120 is displaced relative to the cleaning tank 111.

[0065] To improve the cleaning efficiency of the cleaning assembly 211, see Figure 5 In some embodiments, the number of scrapers 120 can be multiple. According to different requirements, the shapes and sizes of the scrapers 120 can be different or the same. In some embodiments, the cleaning assembly 211 can be cleaned by the relative rotational movement between the scraper 120 and the cleaning assembly 211. Therefore, each scraper 120 can be distributed around an axis parallel to the second direction Y. It can be understood that the surrounding arrangement of each scraper 120 can correspond to the relative rotational movement between the scraper 120 and the cleaning assembly 211, so that the cleaning effect is better. And according to different requirements, in different embodiments, each scraper 120 can be evenly distributed or unevenly distributed. In some embodiments, each cleaning portion can be strip-shaped and extend radially perpendicular to the axis. That is to say, the long sides of each scraper 120 can extend in a direction perpendicular to the axis.

[0066] Further, in order to achieve a better cleaning effect of the cleaning component 211, see Figure 5In some embodiments, the first surface may define a convex rib 121 so that when the scraper 120 and the cleaning component 211 rotate relative to each other about an axis parallel to the second direction Y, the convex rib 121 can rub the cleaning component 211. It is understandable that when cleaning the cleaning component 211, the convex rib 121 can contact and rub the cleaning component 211 to achieve a better cleaning effect. According to different requirements, the convex rib 121 can be in any suitable shape, for example, the convex rib 121 can be in a circular, elliptical, rectangular, triangular, etc. shape. To achieve a better cleaning effect, in some embodiments, the first surface may define a plurality of convex ribs 121.

[0067] For the specific working process of cleaning the cleaning component 211 of the base station 100, see Figure 4 In some embodiments, the base station 100 further includes a driving unit. The driving unit can be connected to the scraper 120. Based on this, the driving unit can be configured to enable the scraper 120 to rotate relative to the cleaning component 211 around an axis parallel to the second direction Y to clean the cleaning component 211. In another embodiment, the cleaning robot 210 can also drive the cleaning component 211 to rotate relative to the scraper 120 around an axis parallel to the second direction Y so that the scraper 120 contacts and cleans the cleaning component 211. It can be understood that in order to rotate the cleaning component 211 relative to the scraper 120, on the one hand, the scraper 120 can be driven to rotate by the driving unit of the base station 100, and on the other hand, the cleaning component 211 can be driven to rotate by the cleaning component 211. It should be noted that the form in which the driving unit is connected to the scraper 120 can be a direct connection or an indirect connection. In contrast to the above embodiments, in other embodiments, the driving unit can be connected to the scraper 120. Based on this, the cleaning assembly 211 can rotate, so that the cleaning assembly 211 can rotate relative to the scraping member 120 around an axis parallel to the second direction Y to clean the cleaning assembly 211.

[0068] To precisely control the relative position between the scraping member 120 and the cleaning assembly 211, so as to achieve a better cleaning effect. Figure 4In some embodiments, the base station 100 further includes a displacement sensor 130. The displacement sensor 130 is used to detect the relative distance between the scraper 120 and the cleaning tank 111. In other words, the displacement sensor 130 can be used to detect the relative position of the first surface and the opening along the second direction Y. Combined with the description of the movement of the scraper 120 in the above embodiments, specifically, in some embodiments, the displacement sensor 130 can be configured to detect the position of the scraper 120 moving along the second direction Y close to the cleaning assembly 211, so that the displacement sensor 130 can detect whether the scraper 120 is located at a position suitable for cleaning the cleaning assembly 211; in some embodiments, the displacement sensor 130 can also be configured to detect the position of the scraper 120 moving away from the cleaning assembly 211, so that the displacement sensor 130 can detect whether the scraper 120 is located at a position that will not interfere with the cleaning assembly 211 cleaning the scraper 120 (i.e., whether the scraper 120 is completely retracted into the opening). Based on the above arrangement, in some embodiments, the displacement sensor 130 can be configured to send a position signal, and the first drive unit (or other drive unit capable of driving the scraper 120 to move) can adjust the position of the scraper 120 relative to the cleaning component 211, or drive the scraper 120 to work, in response to the position signal.

[0069] See also Figure 4 In some embodiments, a turbidity sensor 140 may be further provided in the cleaning tank 111. The turbidity sensor 140 is provided on a side wall of the cleaning tank 111. The turbidity sensor 140 is used to detect the turbidity of the liquid.

[0070] Exemplarily, the working process of the base station 100 in some embodiments is described below. After the cleaning robot 210 docks on the base station 100, the convex rib 121 on the scraper 120 contacts the surface of the first mop and / or the second mop of the cleaning assembly 211, and the pressing rib of the base station 100 presses against the mop, and then the water supply structure can be controlled to supply water, or the water supply structure can be controlled to supply water before the base station 100 enters the cleaning tank 111. The water supply structure can be located at the base station 100 or at the cleaning assembly 211. After that, the soluble stains on the first mop and the second mop can be dissolved in the water, so that the first mop and the second mop can be cleaned. Then the first mop and the second mop are controlled to start rotating. During the rotation, the first mop and the second mop will rub against the ribs 121 on the scraper 120. The ribs 121 can form a scraping effect on the first mop and the second mop, so that the stains on the first mop and the second mop will be cleaned and fall into the cleaning tank 111, thereby removing the stubborn stains on the first mop and the second mop. When it is necessary to clean the cleaning component 211 of the cleaning robot 210, the scraper 120 can easily protrude from the bottom of the cleaning tank 111 (i.e., away from the bottom of the cleaning tank 111), thereby providing the cleaning component 211 of the cleaning robot 210 with sufficient scraping force for efficient cleaning. After that, the cleaning robot 210 can drive the cleaning component 211 to rotate in the cleaning tank 111 to remove the stains in the cleaning tank 111.

[0071] In some embodiments, the base station 100 may further include a barrier structure, which may separate the two groups of scrapers 120 used to clean the first mop and the second mop respectively, so that during the mop rotation cleaning process, the barrier structure can block the contact between the first mop and the second mop, avoiding the first mop and the second mop from squeezing each other and causing water splashing, and also avoiding the waste water from being thrown out and splashing onto the bottom surface 113 of the main body of the cleaning component 211. In addition, the height of the rib 121 may be less than the height of the barrier structure and the height of the wall of the cleaning tank 111 of the base station 100 that accommodates the mops, so as to avoid the rib 121 from splashing the waste water outside the cleaning tank 111.

[0072] In some embodiments, the base station 100 may further include a docking portion, which may be provided with a groove for accommodating the driving wheel of the cleaning component 211. Specifically, when the mop is cleaned, the driving wheel of the cleaning component 211 may be docked in the groove, and the mop is just located in the cleaning tank 111.

[0073] See also Figure 1-Figure 6The second aspect of the present invention also provides a cleaning robot system 200, which includes the base station 100 of any of the above embodiments and a cleaning robot 210. The cleaning robot 210 includes a walking device 212 for driving the cleaning robot 210 to walk on the ground and a cleaning component 211 for cleaning the ground.

[0074] See also Figure 6 In some embodiments, the cleaning component 211 may include a cleaning unit. The cleaning unit may be a part of the cleaning component 211 used to clean the cleaning object. Therefore, the cleaning unit may be a roller brush, a rubber brush, a fur brush, a cleaning pad, a cleaning cloth, an adsorption device, etc. For ease of description, this application is described with the cleaning unit being a mop. Thus, the cleaning unit can be driven to move along the second direction to provide driving force to the base station 100. In contrast to the above embodiments, it is also possible to rely solely on the relative movement of the various parts of the base station 100 so that the first surface can be located at a corresponding position. Specifically, in other embodiments, the base station 100 may include a fourth driving unit, which may be configured to drive the scraper 120 to move or drive the cleaning tank 111 to move, so that the first surface can be located on the side of the opening along the second direction Y away from the cleaning component 211 or move to a position coplanar with the opening.

[0075] For the specific structure of the cleaning component 211. Exemplarily, in some embodiments, the cleaning component 211 includes a cleaning part and a driving component, wherein the cleaning part includes two turntables and a first mop and a second mop arranged on the two turntables, the first mop and the second mop are arranged on the left and right, respectively, and the first mop and the second mop are fixed or removably arranged at the bottom of the turntable. The first mop and the second mop can be made of a material with water absorption and fluff, such as a cleaning pad, a cleaning cloth, etc., and the specific shape can be round, square or any other shape that is compatible with the shape of the turntable. The driving component may include a driving wheel arranged on opposite sides of the main machine, the shape of the first mop and the second mop is round, and the outer edges of the first mop and the second mop intersect. Specifically, the cleaning component 211 sweeps the cleaning surface by the first mop and the second mop, wherein the cleaning surface can be the ground, and the cleaning component 211 moves on the ground so that the first mop and the second mop contact the ground, thereby removing the pollutants on the ground to achieve the effect of cleaning the ground.

[0076] Thanks to the improvement of the base station 100 in the embodiment of the first aspect, the cleaning robot system 200 in the embodiment of the second aspect of the utility model has the same technical effect as the base station 100 in the embodiment of the first aspect, which will not be described in detail here.
