Description

Technical Field

[0001] The present application belongs to the technical field of cleaning systems, and specifically relates to a base station and a cleaning system for a cleaning robot. Background Art

[0002] Existing cleaning robots typically include a main cleaning unit and auxiliary cleaning units located on the sides of the robot. While the main cleaning unit sweeps and mops the area to be cleaned, the auxiliary cleaning units can sweep and mop adjacent corners and edges, effectively cleaning blind spots such as edges and corners that are inaccessible to the main cleaning unit. Existing cleaning robot base stations are typically equipped with a structure for cleaning the main cleaning unit. However, due to the specific placement of the auxiliary cleaning unit on the cleaning robot, the structure within the base station designed to clean the main cleaning unit cannot clean the auxiliary cleaning unit.

[0003] To clean the auxiliary cleaning parts, a separate area and structure for cleaning the auxiliary cleaning parts need to be opened on the base station. For example, the prior art (patent document CN117958696A) discloses a cleaning base station, which has a docking cavity for a cleaning robot to dock and a ramp plate connected to one side of the docking cavity to guide the cleaning robot to dock in the docking cavity. The docking cavity is provided with a main cleaning structure for cleaning the main cleaning parts, and an auxiliary cleaning structure for cleaning the auxiliary cleaning parts is provided on the upper part of the ramp plate and outside the docking cavity. The auxiliary cleaning parts are cleaned at the auxiliary cleaning structure. This technology has the following defects: because the auxiliary cleaning structure is arranged outside the docking cavity and has a certain distance from the main cleaning structure, the sewage, impurities, etc. generated during the cleaning process of the auxiliary cleaning parts cannot be collected in a timely and effective manner. The auxiliary cleaning structure needs to separately set up a collection structure for collecting the scraped dirt, and after cleaning, the user needs to clean the auxiliary cleaning structure separately, which increases the cleaning burden of the user; the exposed arrangement of the auxiliary cleaning structure causes the auxiliary cleaning structure to face a more complex storage environment. If there are pets, children, etc. in the application place of the base station, it is easy to generate uncertain factors. The auxiliary cleaning structure is easy to be blocked, pulled out or damaged by foreign objects, etc., which leads to the inability to effectively clean the auxiliary cleaning parts, affecting the cleaning effect of the auxiliary cleaning parts; the exposed arrangement of the auxiliary cleaning structure also causes the neatness and simplicity of the base station to deteriorate, affecting the user's experience. Utility Model Content

[0004] The present application provides a base station and a cleaning system for a cleaning robot to solve the technical problems of poor correlation between the existing auxiliary cleaning structure and the main cleaning structure, low dirt collection, and increased cleaning burden on users.

[0005] The technical solutions adopted in this application are:

[0006] A base station for a cleaning robot comprises a base station body and a cleaning tray, the base station body having a docking cavity for the cleaning robot to dock, the cleaning tray being at least partially accommodated in the docking cavity, the cleaning tray comprising a main cleaning tank, at least one cavity being provided between the inner wall surface of the docking cavity and the cleaning robot docked in the docking cavity, at least part of the edge cleaning element of the cleaning robot being located in the cavity, the cavity being communicated with the main cleaning tank; the cavity comprising a cavity side wall, the cavity wall and / or the main cleaning tank being provided with a water supply portion.

[0008] The base station body is provided with a first accommodating cavity formed by being recessed inward from the inner wall surface of the docking cavity, and / or the cleaning tray is provided with a second accommodating cavity protruding toward the inner wall surface of the docking cavity; wherein, the first accommodating cavity and / or the second accommodating cavity form the accommodating cavity.

[0009] A bracket is provided in the first accommodating cavity, and the bracket is provided with a drain plate that abuts against the cleaning disc to drain the liquid to the main cleaning tank; the drain plate is provided with an abutment structure that protrudes toward the first accommodating cavity to abut against the edge cleaning member; and / or the cleaning disc includes a main disc and an auxiliary disc that protrudes outward along the side wall of the main disc to extend into the accommodating cavity, the main cleaning tank is provided on the main disc, and the second accommodating cavity is provided on the auxiliary disc; the auxiliary disc is provided with an abutment structure that protrudes toward the cavity to abut against the edge cleaning member.

[0010] The base station body is provided with a spray hole for spraying cleaning liquid onto the edge cleaning member.

[0011] The edge cleaning member has an annular mop for cleaning the surface to be cleaned, and the axis of the spray hole is arranged at an angle to the outer surface of the portion of the annular mop facing the side wall of the cavity.

[0012] The base station body is provided with a spray hole for spraying liquid into the cavity, and a wiper extending into the cavity to abut against the edge cleaning member. Along the rotation direction of the edge cleaning member, the wiper is located on the downstream side of the spray hole.

[0013] The edge cleaning member includes a first rotating wheel, a second rotating wheel and an annular mop arranged around the outside of the first rotating wheel and the second rotating wheel; or, the edge cleaning member includes a first rotating wheel, a second rotating wheel, at least one third rotating wheel, and an annular mop arranged around the outside of the first rotating wheel, the second rotating wheel and the third rotating wheel.

[0014] A splash shield is protruding from the bottom wall of the cleaning tray to at least partially block water splashing when the edge cleaning member rotates, and the splash shield extends along the direction in which the cleaning robot enters and exits the docking cavity to separate the main cleaning tank into a dirt suction area and an auxiliary cleaning area connected to the cavity.

[0015] The splash shield is provided with a passage for communicating the dirt suction area and the auxiliary cleaning area.

[0016] The present application also discloses a cleaning system, comprising a cleaning robot, the cleaning robot comprising a body, a main cleaning member, and a side cleaning member, the side cleaning member being movably mounted on the body to have a working state and a reset state, the cleaning system further comprising the base station for the cleaning robot as described above, wherein when the cleaning robot is docked in the docking cavity, the side cleaning member is at least partially located in the cavity. The working state includes the side cleaning member being movably extended into the cavity, or the side cleaning member being immovably extended and merely positioned in the cavity, moving up and down, or the side cleaning member being immovable and remaining stationary in the cavity. The reset state is the static reset state of the side cleaning member before becoming movable.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. A cavity is provided between the inner wall surface of the docking cavity of the present application and the cleaning robot docked in the docking cavity. At least part of the edge cleaning part of the cleaning robot can be located in the cavity for cleaning. The implicit arrangement of the cavity not only makes full use of the space inside the base station, making the base station more compact, which is conducive to reducing the overall size requirements of the base station for the storage space, but also the implicit cavity can reduce the impact of the base station storage environment on the cavity, making the cavity less likely to be blocked or damaged by foreign objects, so that after the cleaning robot docks in the docking cavity, the edge cleaning part can smoothly enter the cleaning mode.

[0019] Moreover, the cavity and the main cleaning tank are connected by a design in which the cavity wall and / or the main cleaning tank are provided with a water supply part, so that the dirt, solids, liquids, etc. generated by the edge cleaning parts during the cleaning process can enter the main cleaning tank, and the dirt generated by the main cleaning parts during the cleaning process can also enter the main cleaning tank, thereby improving the collection degree of dirt during the cleaning process of the cleaning robot, facilitating centralized treatment of dirt, and improving user experience.

[0020] 2. As a preferred embodiment of the present application, the base station body is provided with a first accommodating cavity recessed inward from the inner wall of the docking cavity, the first accommodating cavity forming the accommodating cavity. By forming the accommodating cavity by recessing the inner wall of the docking cavity, the accommodating cavity can be arranged by utilizing the redundant space within the base station body without increasing the external dimensions of the base station body, thereby improving space utilization and contributing to the miniaturization of the base station body. Furthermore, by forming the accommodating cavity by recessing the inner wall of the docking cavity, liquid splashing generated by the edge cleaning element during the cleaning process can be controlled within a relatively small space, reducing contamination to the rest of the docking cavity and reducing the cleaning burden on the user. Furthermore, since the cleaning of the edge cleaning element is confined within the accommodating cavity, the liquid flow and mechanical vibration during the cleaning process are also confined to a smaller cavity, thereby helping to reduce noise generated during the cleaning process. Furthermore, compared to an embodiment in which the docking cavity is maximized to form the accommodating cavity between the cleaning tray and the inner wall of the docking cavity, the accommodating cavity in this embodiment is formed by recessing the inner wall of the docking cavity, which helps to reduce the volume of the docking cavity, thereby reducing the space that may cause resonance during the cleaning process of the cleaning robot and improving the stability of the base station body structure.

[0021] 3. As a preferred embodiment of the present application, the cleaning tray is provided with a second accommodating cavity protruding toward the inner wall of the docking cavity, and the second accommodating cavity forms a accommodating cavity. The second accommodating cavity is added to the cleaning tray for accommodating and cleaning the edge cleaning parts, which improves the integration of the cleaning tray, so that the cleaning tray has both a main cleaning tank for accommodating the main cleaning parts and a second accommodating cavity for accommodating the edge cleaning parts, which makes the functions more integrated. Moreover, after the cleaning robot finishes cleaning, it is convenient for the user to clean the cleaning tray uniformly, thereby reducing the cleaning burden of the user. From another perspective, the provision of a second accommodating cavity on the cleaning tray for accommodating and cleaning the edge cleaning parts can simplify the structural design of the base station body and reduce the complexity of the processing and manufacturing of the base station body.

[0022] Furthermore, the cleaning disc includes a main disc and an auxiliary disc that protrudes outward from the sidewall of the main disc to extend into the receiving cavity. The second receiving cavity is provided on the auxiliary disc, and the auxiliary disc is provided with an abutment structure that protrudes into the receiving cavity to abut against the edge cleaning member. The abutment structure abuts against the edge cleaning member, thereby producing a scraping effect on the edge cleaning member. During the operation of the edge cleaning member, the abutment structure can scrape off dirt adhering to the edge cleaning member, thereby improving the cleaning effect of the edge cleaning member.

[0023] 4. As a preferred embodiment of the present application, the base station body is provided with a spray hole, through which cleaning liquid is sprayed onto the edge cleaning parts, thereby more quickly cleaning away dirt and dust attached to the cleaning parts and improving cleaning efficiency. Moreover, the sprayed cleaning liquid can form a flushing effect on the dirt scraped off from the edge cleaning parts, causing the dirt in the cavity to flow into the main cleaning tank, facilitating centralized treatment of the dirt. In particular, by directly spraying the cleaning liquid onto the edge cleaning parts, the generated sewage flows back from the inclined cavity to the main cleaning tank under the action of gravity, and is recovered in the main cleaning tank to the sewage tank or directly discharged to the floor drain, thus achieving live water cleaning of the edge cleaning parts, that is, completing fully automatic live water washing and mopping, greatly improving the degree of automation and the self-cleaning ability of the edge cleaning parts.

[0024] Furthermore, the edge cleaning element has a ring-shaped mop for cleaning the surface to be cleaned, and the axis of the spray hole is arranged at an angle to the outer surface of the part of the ring-shaped mop facing the side wall of the cavity. On the one hand, the cleaning liquid can cover the outer surface of the ring-shaped mop more effectively and form a flushing effect on the outer surface of the ring-shaped mop, thereby improving the cleaning performance. On the other hand, the large-area coverage of the ring-shaped mop by the cleaning liquid can reduce the waste of cleaning liquid and save cleaning liquid. Moreover, through reasonable angle arrangement, the splashing of cleaning liquid during the spraying process can be reduced, so that as much dirt as possible is splashed to the bottom wall of the cavity and flows into the main cleaning tank with the cleaning liquid, reducing the user's cleaning burden on the cavity. In addition, the angle formed by the spray hole and the surface of the ring-shaped mop can reduce the direct impact of the cleaning liquid on the ring-shaped mop, thereby reducing the wear on the ring-shaped mop and extending its service life.

[0025] 5. As a preferred embodiment of the present application, the base station body is further provided with a wiper extending into the cavity to abut against the edge cleaning member. The wiper is located on the downstream side of the spray hole along the rotation direction of the edge cleaning member to ensure that after the edge cleaning member is sprayed and cleaned, the wiper can effectively remove excess water from the edge cleaning member. This not only helps to reduce the growth of bacteria and mold on the edge cleaning member and maintain the hygiene of the edge cleaning member, but also the water draining function of the wiper on the edge cleaning member can speed up the drying process of the edge cleaning member and reduce corrosion or damage to the edge cleaning member caused by prolonged wetting. In the scenario where the cleaning robot is docked in the docking cavity for a short time, the wiper can promptly remove moisture from the edge cleaning member, which can reduce the occurrence of problems such as poor cleaning effect on the surface to be cleaned due to excessive moisture when the cleaning robot continues to work, or residual water stains that can easily cause slips.

[0026] 6. As a preferred embodiment of the present application, the bottom wall of the cleaning tray is provided with a splash shield extending in the direction of the cleaning robot entering and exiting the docking cavity to separate the main cleaning tank into a dirt suction area and an auxiliary cleaning area connected to the cavity. Dirt accumulated in the main cleaning tank can be sucked in by the suction port of the cleaning robot, thereby reducing the cleaning burden on the user. By providing the splash shield, on the one hand, the main cleaning tank can be divided into the dirt suction area and the auxiliary cleaning area to avoid cross-contamination between the main cleaning parts and the edge cleaning parts during the cleaning process, thereby ensuring the cleaning effect. On the other hand, the splash shield can reduce splashing of water during the cleaning of the edge cleaning parts, especially to prevent splashing dirt from splashing near the suction port of the cleaning robot, thereby reducing the cleaning burden on the user near the suction port of the cleaning robot.

[0050] Example 1:

[0051] like Figure 1 As shown, a base station for a cleaning robot includes a base station body and a cleaning tray 2. The base station body has a docking cavity 11 for the cleaning robot to dock. The cleaning tray 2 is at least partially accommodated in the docking cavity 11. The cleaning tray 2 includes a main cleaning tank 211. At least one cavity is provided between the inner wall surface of the docking cavity 11 and the cleaning robot docked in the docking cavity 11. At least part of the edge cleaning member 3 of the cleaning robot can be located in the cavity. The cavity is connected to the main cleaning tank 211, and the cavity includes a cavity wall, preferably a cavity side wall. The cavity wall and / or the main cleaning tank are provided with a water supply. Preferably, the water supply is used to pass fluid from the cavity wall to the main cleaning tank, or from the main cleaning tank to the cavity wall, that is, to provide fluid to the cavity wall or the main cleaning tank. The fluid can be sewage or cleaning liquid. For example, if a fluid is provided to the main cleaning tank, a cleaning liquid can be provided to the main cleaning tank to facilitate self-cleaning of the main cleaning tank, or sewage can be provided to the main cleaning tank to collect sewage from the cavity wall to the main cleaning tank for easy discharge from the main cleaning tank. For another example, if a fluid is provided to the cavity wall, a cleaning liquid can be provided to the cavity wall to facilitate self-cleaning of the cavity wall, or sewage / clean water can be provided to the cavity wall to use the fluid to remove solid or liquid dirt adhering to the cavity wall.

[0052] like Figure 5As shown, the base station in this embodiment is used for a cleaning robot. The cleaning robot is equipped with a main cleaning unit and an edge cleaning unit 3. The main cleaning unit is located at the bottom of the cleaning robot. The edge cleaning unit 3 is located on the side of the cleaning robot. When the cleaning robot is in operation, the main cleaning unit sweeps and mops the main area of ​​the surface to be cleaned, while the edge cleaning unit 3 is movably mounted on the cleaning robot to clean edge areas such as walls and corners.

[0053] In this embodiment, a cavity is provided between the inner wall surface of the docking cavity 11 and the cleaning robot docked in the docking cavity 11. At least part of the edge cleaning member 3 of the cleaning robot can be located in the cavity for cleaning. The implicit arrangement of the cavity not only makes full use of the space inside the base station, making the base station more compact, which is beneficial to reducing the overall size requirements of the base station for the storage space, but also the implicit cavity can reduce the impact of the base station storage environment on the cavity, making the cavity less likely to be blocked or damaged by foreign objects, so that after the cleaning robot docks in the docking cavity 11, the edge cleaning member 3 can smoothly enter the cleaning mode.

[0054] Moreover, the connection design between the cavity and the main cleaning tank 211, the cavity wall and / or the main cleaning tank is provided with a water supply part, so that the dirt, solid and liquid, etc. generated by the edge cleaning part 3 during the cleaning process can enter the main cleaning tank 211, and the dirt generated by the main cleaning part during the cleaning process can also enter the main cleaning tank 211, thereby improving the collection degree of dirt during the cleaning process of the cleaning robot, facilitating centralized treatment of dirt, and improving user experience.

[0055] The base station body has a docking cavity 11 for the cleaning robot to dock, and the docking cavity 11 has an opening for the cleaning robot to move in and out. In one example, the cleaning tray 2 is partially accommodated in the docking cavity 11 and the other part is accommodated outside the docking cavity 11. In another example, Figure 4 As shown, the cleaning tray 2 can be completely accommodated in the docking cavity 11 .

[0056] This embodiment also does not limit the connection method between the cleaning tray 2 and the base station body. In one example, the cleaning tray 2 is fixedly connected to the base station body, for example, by welding, bonding, etc. In another example, the cleaning tray 2 is detachably mounted to the base station body, for example, by snap-fitting, magnetically attaching, etc., so that the user can easily remove the cleaning tray 2 from the docking cavity 11 to thoroughly clean the cleaning tray 2 and reduce the possibility of bacterial growth.

[0057] The cavity in this application can adopt any of the following embodiments:

[0058] Embodiment 1: The receiving cavity is formed between the inner wall surface of the docking cavity 11 and the outer wall surface of the cleaning tray 2. The cleaning tray 2 is provided with a notch for the edge cleaning member 3 to extend into the receiving cavity.

[0059] Implementation method 2: Figure 1 As shown, the base station body is provided with a first accommodating cavity 12 recessed inward from the inner wall of the docking cavity 11, and the cleaning tray 2 is provided with a second accommodating cavity 221 protruding toward the inner wall of the docking cavity 11. The first accommodating cavity 12 and the second accommodating cavity 221 form a accommodating cavity. By forming the first accommodating cavity 12 by recessing the inner wall of the docking cavity 11 and the second accommodating cavity 221 protruding toward the inner wall of the docking cavity 11 to form a accommodating cavity together with the first accommodating cavity 12, the accommodating cavity can be arranged by utilizing the redundant space within the base station body 1 without increasing the external dimensions of the base station body 1, thereby improving space utilization and contributing to the miniaturization of the base station design. Furthermore, the accommodating cavity formed by the recessed inner wall of the docking cavity 11 allows liquid splashing generated by the edge cleaning element 3 during the cleaning process to be contained within a relatively small space, reducing contamination of the remaining areas within the docking cavity 11 and reducing the cleaning burden on the user. Furthermore, the cleaning of the edge cleaning element 3 is confined to the accommodating cavity, and the liquid flow and mechanical vibration during the cleaning process are also confined to the smaller cavity, thereby helping to reduce noise generated during the cleaning process. In addition, compared with the above-mentioned embodiment 1, the cavity in this embodiment 2 is formed by the depression of the inner wall surface of the docking cavity 11, which helps to reduce the volume of the docking cavity 11, thereby reducing the space that may cause resonance during the cleaning process of the cleaning robot and improving the stability of the base station body 1 structure.

[0060] As a preferred example of the second embodiment, Figure 3 As shown, the cleaning tray 2 includes a main tray 21 and an auxiliary tray 22 that protrudes outward from the sidewall of the main tray 21 to extend into the receiving cavity. The main tray 21 is provided with a main cleaning groove 211, and the second receiving cavity 221 is provided in the auxiliary tray 22. The auxiliary tray 22 is provided with an abutment structure that protrudes into the receiving cavity to abut against the edge cleaning element 3. The abutment structure abuts against the edge cleaning element 3, thereby producing a scraping effect on the edge cleaning element 3. During the operation of the edge cleaning element 3, the abutment structure can scrape off dirt adhering to the edge cleaning element 3, thereby improving the cleaning effect of the edge cleaning element 3.

[0061] Preferably, the main disk 21 and the auxiliary disk 22 are integrally formed.

[0062] In this example, the abutment structure can be any of the following examples:

[0063] Example 1: The abutting structure is a comb tooth provided on the auxiliary plate 22 , and one end of the comb tooth abuts against the edge cleaning member 3 to achieve scraping of the edge cleaning member 3 .

[0064] Example 2: If Figure 3 As shown, the abutment structure is a plurality of spaced protrusions 222 provided on the auxiliary disc 22. Different from the comb teeth in Example 1, the density of the protrusions 222 is smaller than that of the comb teeth, and the contact area between the protrusions 222 and the surface of the edge cleaning member 3 is increased.

[0065] More specifically, if Figure 3 As shown, the auxiliary tray 22 includes an outer convex wall 2211 facing the direction in which the edge cleaning element 3 enters and exits the second accommodating chamber 221, a transition wall 2212 connecting the outer convex wall 2211 and the bottom wall of the main tray 21, and a connecting wall 2213 connecting the outer convex wall 2211 and the side wall of the main tray 21. The outer convex wall 2211, the transition wall 2212, and the connecting wall 2213 cooperate to form the second accommodating chamber 221; abutment structures are provided on the outer convex wall 2211, the transition wall 2212, and / or at the connection between the outer convex wall 2211 and the transition wall 2212. Furthermore, the transition wall 2212 is curved to allow dirt in the second accommodating chamber 221 to flow smoothly into the main cleaning tank 211 under the drainage effect of the transition wall 2212.

[0066] Preferably, the abutting structure and the auxiliary plate 22 are integrally formed to reduce the increase in assembly steps caused by separate forming.

[0067] As a preference, Figure 3 As shown, the abutment structures are provided in multiple rows, with adjacent rows of abutment structures being staggered along the direction in which the edge cleaning member 3 enters and exits the second accommodating chamber 221. On the one hand, the staggered abutment structures can better scrape the mop of the edge cleaning member 3. They can abut and scrape different parts of the mop along the width of the edge cleaning member 3, thereby loosening the edge cleaning member 3. This facilitates the subsequent spraying of cleaning liquid by the spray holes 13 onto the edge cleaning member 3, allowing the cleaning liquid to fully penetrate and flush the tufts on the mop, thereby improving the cleaning effect.

[0068] Preferably, the abutment structures are provided in multiple rows, and the interference between the abutment structures in two adjacent rows and the edge cleaning members 3 is different. Due to the different interference amounts, the edge cleaning members 3 can be pulled by the abutment structures during their rotation, thereby facilitating the removal of dirt and improving the cleaning effect.

[0069] As a preferred embodiment of the present application, Figure 2 As shown, the base station body 1 is provided with spray holes 13 for spraying cleaning fluid onto the edge cleaning elements 3. Spraying cleaning fluid onto the edge cleaning elements 3 through the spray holes 13 more quickly removes dirt and dust adhering to the cleaning elements, improving cleaning efficiency. Furthermore, the sprayed cleaning fluid flushes away dirt scraped from the edge cleaning elements 3, causing the dirt within the chamber to flow into the main cleaning tank 211, facilitating centralized treatment of the dirt.

[0070] In this embodiment, the relative position relationship between the spray hole 13 and the edge cleaning member 3 can adopt any one of the following examples:

[0071] Example 1: The edge cleaning member 3 has an annular mop 31 for cleaning the surface to be cleaned, and the spray hole 13 is provided on the side wall of the cavity to face the outer surface of the annular mop 31 .

[0072] Example 2: Figure 1 As shown, the edge cleaning member 3 includes an annular mop 31 for cleaning the surface to be cleaned. The axis of the spray hole 13 is arranged at an angle α to the outer surface of the portion of the annular mop 31 facing the side wall of the chamber. More specifically, the spray hole 13 is provided on the upper portion of the side wall of the chamber, or the spray hole 13 is provided on the top wall of the chamber.

[0073] The axis of the spray hole 13 is arranged at an angle α to the outer surface of the portion of the annular mop 31 that faces the side wall of the cavity. On the one hand, this allows the cleaning liquid to more effectively cover the outer surface of the annular mop 31 and form a flushing effect on the outer surface of the annular mop 31, thereby improving cleaning performance. On the other hand, the large area coverage of the annular mop 31 by the cleaning liquid can reduce the waste of cleaning liquid and save cleaning liquid. Furthermore, through a reasonable angle arrangement, the splashing of the cleaning liquid during the spraying process can be reduced, so that as much dirt as possible is splashed onto the bottom wall of the cavity and flows into the main cleaning tank 211 with the cleaning liquid, thereby reducing the user's cleaning burden on the cavity. In addition, the angle formed by the spray hole 13 and the surface of the annular mop 31 can reduce the direct impact of the cleaning liquid on the annular mop 31, thereby reducing the wear on the annular mop 31 and extending its service life.

[0074] As a preference, Figure 1 As shown, the spray hole 13 is provided on the top wall of the cavity, with the axis of the spray hole 13 parallel to the vertical direction, thereby reducing the space occupied by the structure forming the spray hole 13 within the cavity. Furthermore, the cleaning liquid is sprayed downward toward the outer surface of the annular mop 31, creating a certain flushing effect on the outer surface of the annular mop 31, further enhancing the cleaning effect of the annular mop 31. The angle α is set to 0°≤α≤20° to accommodate the extended length of the edge cleaning element 3, the space occupied by the cavity in the docking cavity 11, and the cleaning effect of the edge cleaning element 3. Furthermore, 0°<α≤10°, on the one hand, can further reduce the volume of the edge cleaning member 3 extending into the cavity, reducing the space occupied by the cavity to the base station body, and on the other hand, a smaller angle is easier to form a flushing effect, which can more easily flush the tufts on the surface of the annular mop 31, so as to further reduce the adhesion of dirt on the surface of the annular mop 31, and when the tufts are dispersed by the cleaning liquid, the cleaning liquid can more easily penetrate into the roots of the tufts, so as to further enhance the cleaning effect on the roots of the tufts.

[0075] As a preferred implementation method under this embodiment, Figure 2 As shown, the base station body 1 is equipped with a spray hole 13 that sprays liquid into the cavity, and a wiper blade 14 that extends into the cavity to abut against the edge cleaning member 3. The wiper blade 14 is located downstream of the spray hole 13 along the rotation direction of the edge cleaning member 3. After the edge cleaning member 3 is sprayed and cleaned, the wiper blade 14 effectively removes excess water from the edge cleaning member 3, helping to reduce the growth of bacteria and mold on the edge cleaning member 3 and maintain its hygiene. Furthermore, the wiper blade 14's function of draining water from the edge cleaning member 3 accelerates the drying process and reduces corrosion or damage caused by prolonged wetting. When the cleaning robot is briefly docked in the docking cavity 11, the wiper blade 14 promptly removes water from the edge cleaning member 3, reducing the risk of problems such as poor cleaning performance due to excess moisture or slips caused by residual water stains when the cleaning robot continues to operate.

[0076] As a preferred example of this embodiment, Figure 1 As shown, the wiper blade 14 is disposed on the top wall of the cavity and extends downward to abut against the edge cleaning member 3. Furthermore, the abutment position of the wiper blade 14 and the edge cleaning member 3 is lower than the highest point on the outer surface of the edge cleaning member 3. This arrangement allows the cleaning liquid and dirt scraped off by the wiper blade 14 to flow downward into the cavity along with the cleaning liquid sprayed from the spray holes 13. This can not only reduce liquid splashing, but also prevent the cleaning liquid on the upstream side from continuing to flow into the area scraped by the wiper blade 14 due to gravity, resulting in a poor drainage effect.

[0077] This embodiment does not limit the structural shape of the edge cleaning member 3, and it can adopt any one of the following embodiments:

[0078] Embodiment 3: The edge cleaning member 3 includes a first rotating wheel 32 , a second rotating wheel 33 and an annular mop 31 wound around the outer sides of the first rotating wheel 32 and the second rotating wheel 33 .

[0079] Embodiment 4: The edge cleaning member 3 comprises a first rotating wheel 32, a second rotating wheel 33, at least one third rotating wheel 34, and an annular mop 31 wound around the outside of the first rotating wheel 32, the second rotating wheel 33 and the third rotating wheel 34. Figure 2 As shown, the edge cleaning member 3 includes a first rotating wheel 32, a second rotating wheel 33 and a third rotating wheel 34, and the edge cleaning member 3 is triangular in shape as a whole.

[0080] As a preferred implementation method under this embodiment, Figure 3As shown, a splash shield 23 is provided on the bottom wall of the cleaning tray 2 to at least partially block water splashing when the edge cleaning element 3 rotates. The splash shield 23 extends along the direction in which the cleaning robot enters and exits the docking chamber 11, thereby dividing the main cleaning tank 211 into a dirt suction area 2112 and an auxiliary cleaning area 2111 connected to the cavity. Dirt accumulated in the main cleaning tank 211 can be sucked into the dirt suction port of the cleaning robot, thereby reducing the cleaning burden on the user. By providing the splash shield 23, on the one hand, the main cleaning tank 211 can be divided into the dirt suction area 2112 and the auxiliary cleaning area 2111, thereby avoiding cross-contamination between the main cleaning element and the edge cleaning element 3 during the cleaning process, thereby ensuring the cleaning effect. On the other hand, the splash shield 23 can reduce water splashing during the cleaning of the edge cleaning element 3, especially preventing splashed dirt from splashing near the dirt suction port of the cleaning robot, thereby reducing the cleaning burden on the user near the dirt suction port of the cleaning robot.

[0081] In order to prevent the dirt in the auxiliary cleaning area 2111 from not being collected by the suction port of the cleaning robot, thereby forming a cleaning dead zone in the cleaning tray 2, this embodiment can adopt any one of the following examples to solve this technical problem:

[0082] Example 1: Figure 3 As shown, the splash shield 23 is provided with a channel 231 for connecting the dirt suction area 2112 and the auxiliary cleaning area 2111. Figure 4 As shown, the sewage suction area 2112 and the auxiliary cleaning area 2111 are connected by a channel 231. At least a portion of the sewage generated during the cleaning of the edge cleaning element 3 can pass through the channel 231 from the auxiliary cleaning area 2111 into the sewage suction area 2112 and ultimately be absorbed by the sewage suction port of the cleaning robot. This not only reduces the burden of the user cleaning the cleaning tray 2 by themselves, but also avoids the formation of a cleaning dead zone in the cleaning tray 2. The channel 231 can be in the shape of a hole, a notch, etc.

[0083] Example 2: The splash shield 23 is not provided with a channel 231, the auxiliary cleaning area 2111 is located at a higher height than the sewage suction area 2112, or a guide surface is provided between the auxiliary cleaning area 2111 and the sewage suction area 2112, so that the sewage collected in the auxiliary cleaning area 2111 during the cleaning process of the edge cleaning part 3 can flow and gather to the sewage suction area 2112, and finally be absorbed by the sewage suction port of the cleaning robot.

[0084] This embodiment also discloses a cleaning system, including a cleaning robot, which includes a body 4, a main cleaning part and an edge cleaning part 3. The edge cleaning part 3 can be movably arranged on the body 4 to have a working state and a reset state. The cleaning system also includes the above-mentioned base station for the cleaning robot. When the cleaning robot is docked in the docking chamber 11, the edge cleaning part 3 is at least partially located in the chamber.

[0085] This embodiment does not limit the movement of the edge cleaning member 3.

[0086] In one embodiment, the edge cleaning member 3 is retractably arranged on the machine body, and the edge cleaning member 3 is extended to be in a position as shown in FIG. Figure 5 In the working state shown, the edge cleaning member 3 is retracted to be in the Figure 6 When the cleaning robot is docked at the docking cavity 11 , the edge cleaning member 3 extends into the cavity, thereby cleaning the edge cleaning member 3 .

[0087] In another embodiment, the edge cleaning member 3 is movably mounted on the body. The edge cleaning member 3 is lowered to enter the working state and raised to enter the reset state. When the cleaning robot is docked in the docking cavity 11, the edge cleaning member 3 is lowered to enter the cavity, thereby cleaning the edge cleaning member 3.

[0088] In another embodiment, by rationalizing the structures of the docking cavity and the receiving cavity, when the cleaning robot is docked in the docking cavity, the edge cleaning member 3 can be located in the receiving cavity in an inactive state, so that the edge cleaning member 3 is in a state capable of cleaning.

[0089] Example 2:

[0090] The structure and principle of this embodiment 2 are basically the same as those of embodiment 1, and the difference lies in the location and formation method of the cavity.

[0091] like Figure 7 As shown, the base station body is provided with a first accommodating cavity 12 formed by recessing the inner wall of the docking cavity 11 inwardly. The first accommodating cavity 12 forms a accommodating cavity. By recessing the inner wall of the docking cavity 11 to form the accommodating cavity, the accommodating cavity can be arranged by utilizing the redundant space within the base station body 1 without increasing the external dimensions of the base station body 1, thereby improving space utilization and contributing to the miniaturization of the base station design.

[0092] As a preferred implementation method under this embodiment, Figure 7 As shown, a bracket 5 is provided in the first accommodating chamber 12, and the bracket 5 is provided with a drain plate 51 that contacts the cleaning tray 2 to drain the liquid into the main cleaning tank 211. By providing the drain plate 51, the dirt generated during the cleaning of the edge cleaning element 3 can be drained into the main cleaning tank 211, so that the dirt generated during the cleaning of the edge cleaning element 3 and the main cleaning element can be centrally processed. Figure 7 As shown, the guide plate 51 is provided with an abutting structure 52 protruding toward the first accommodating cavity 12 to abut against the edge cleaning member 3. Figure 8As shown, the abutment structure 52 abuts against the edge cleaning member 3, thereby producing a scraping effect on the edge cleaning member 3. During the operation of the edge cleaning member 3, the abutment structure 52 can scrape off dirt attached to the edge cleaning member 3, thereby improving the cleaning effect of the edge cleaning member 3. The abutment structure 52 can be, for example, a comb tooth, a protrusion, or the like provided on the guide plate.

[0093] Example 3:

[0094] The structure and principle of this embodiment 3 are basically the same as those of embodiment 1, and the difference lies in the location and formation method of the cavity.

[0095] like Figure 9 As shown, the cleaning tray 2 is provided with a second accommodating cavity 221 protruding toward the inner wall surface of the docking cavity 11, and the second accommodating cavity 221 forms a accommodating cavity. Figure 10 As shown, the edge cleaning member 3 extends into the cavity to achieve cleaning. Furthermore, an abutment structure 6 is provided in the cavity to abut against the edge cleaning member 3 to scrape dirt therefrom.

For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
