Detailed Embodiments

[0027] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are for illustrative purposes in nature and are not intended to limit the present invention.

[0028] To further illustrate the principle and structure of the present invention, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0029] Referring to Figure 1 and Figure 2 In an embodiment of the present application, a cleaning base station 100 is provided, which can be used in cooperation with a cleaning robot. The cleaning base station 100 includes a base, a sewage tank 10, and a cleaning component 20.

[0030] Among them, the sewage tank 10 is arranged on the base. An accommodating cavity 11 is provided inside the sewage tank 10, and the accommodating cavity 11 is used to store the sewage generated by the mopping member for cleaning the cleaning robot. After the sewage in the sewage tank 10 is discharged, a large amount of impurities will remain inside the sewage tank 10, and it is necessary to clean the inside of the sewage tank 10. The cleaning component 20 is arranged in the accommodating cavity 11, and the cleaning component 20 includes a liquid storage flow channel 21, and the liquid storage flow channel 21 is communicated with the accommodating cavity 11. Cleaning liquid flows inside the liquid storage flow channel 21, which is used to clean the inside of the sewage tank 10.

[0031] In this embodiment, the liquid storage flow channel 21 is a pipe structure. In other examples of this embodiment, the liquid storage flow channel 21 can also be other structural forms, such as a spraying member with multiple water outlets, a liquid outlet member with multiple openings, etc., as long as it can allow the cleaning liquid to flow through and clean the inside of the sewage tank 10.

[0032] The sewage tank 10 is integrally in a box structure, and the liquid storage flow channel 21 is vertically arranged at the bottom of the sewage tank 10. An installation hole is opened on the bottom wall of the sewage tank 10, and the liquid storage flow channel 21 is fixedly arranged through the installation hole. The inlet of the liquid storage flow channel 21 is arranged outside the sewage tank 10, and the outlet of the liquid storage flow channel 21 is arranged inside the sewage tank 10. Cleaning liquid flows inside the liquid storage flow channel 21, and the cleaning liquid enters the accommodating cavity 11 to clean the inside of the sewage tank 10.

[0033] In this embodiment, the cleaning base station 100 may further include a cleaning box, and the inside of the cleaning box is used to accommodate the cleaning liquid. The inlet of the liquid storage flow channel 21 is communicated with the inside of the cleaning box, so that the cleaning liquid in the cleaning box enters the inside of the sewage tank 10 through the liquid storage flow channel 21.

[0034] A driving pump is provided on the liquid storage flow channel 21 of this embodiment, and the driving pump is used to pump the cleaning liquid into the liquid storage flow channel 21. By controlling the cleaning pump, the liquid inflow amount of the cleaning liquid in the liquid storage flow channel 21 can be controlled.

[0035] The cleaning liquid flowing through the liquid storage channel 21 can be clean water, organic cleaning agent, inorganic cleaning agent, or a liquid mixture containing a cleaning agent, etc., as long as it can clean the stains in the sewage tank 10. Here, the composition of the cleaning liquid is not overly limited.

[0036] In this embodiment, the cleaning base station 100 includes a cleaning tank 30. The cleaning tank 30 is arranged on the base and is disposed below the sewage tank 10. The cleaning tank 30 is used for cleaning the mopping member of the cleaning robot, that is, placing the mopping member in the cleaning tank 30, and the clean water in the cleaning tank 30 can clean the mopping member.

[0037] The mopping member of the cleaning robot can be a rotating mop in the shape of a disc or approximately a disc, or a flat mop or a vibrating movable mop up and down, or a sponge roller brush or other rollers wrapped with mopping materials such as cloth strips, etc. After the mopping member is cleaned in the cleaning tank 30, a large amount of sewage will be generated in the cleaning tank 30.

[0038] Combined with Figure 3 and Figure 4 , the cleaning base station 100 of this embodiment further includes a sewage pipe 40, and the extending direction of the sewage pipe 40 is the same as the extending direction of the liquid storage channel 21. The sewage pipe 40 is fixedly arranged through the bottom wall of the sewage tank 10. The inlet of the sewage pipe 40 is communicated with the inside of the cleaning tank 30, and the outlet of the sewage pipe 40 is communicated with the sewage tank 10. A power pump is provided on the sewage pipe 40, and the power pump is used to pump the sewage in the cleaning tank 30 into the sewage tank 10 through the sewage pipe 40.

[0039] Combined with Figure 5 and Figure 6 , in this embodiment, the cleaning assembly 20 further includes a support member 50 and a transition member 60. The support member 50 includes a support main body 51 and a connecting portion 52. The support main body 51 has an umbrella-like structure, and the outer contour of the connecting portion 52 is circular. The periphery of the connecting portion 52 is fixedly connected to the inner surface of the support main body 51. A connecting hole is formed in the connecting portion 52, and the liquid storage channel 21 is fixedly arranged through the connecting hole, so that the support main body 51 is arranged on the top of the liquid storage channel 21, and the outlet of the liquid storage channel 21 is arranged outside the support main body 51.

[0040] The transition member 60 is rotatably arranged outside the support main body 51, and the rotation axis of the transition member 60 is the same as the extending direction of the liquid storage channel 21. The outlet of the liquid storage channel 21 is arranged on the outer surface of the transition member 60, and the outer surface of the transition member 60 is used to receive the cleaning liquid flowing out of the liquid storage channel 21. In addition, the outlet of the liquid storage channel 21 can also be arranged above the transition member 60.

[0041] The transition member 60 of this embodiment includes a transition main body 61 and a flanging portion 62 provided on the periphery of the transition main body 61. The transition main body 61 has an umbrella-like structure, and the flanging portion 62 is bent from the edge of the transition main body 61 towards the top of the transition main body 61. A plurality of liquid outlets 63 are provided on the flanging portion 62, and the plurality of liquid outlets 63 are arranged at intervals along the circumference of the flanging portion 62.

[0042] In other examples of this embodiment, the transition member 60 further includes fan blade portions. A plurality of fan blade portions can be provided, and the plurality of fan blade portions are arranged at intervals on the transition main body 61.

[0043] When the transition member 60 rotates, the fan blade portions provided on the transition main body 61 can drive the air flow to form a flowing wind inside the sewage tank 10. The fan blade portions of this embodiment can be provided on the outer surface of the transition main body 61, which can not only assist the cleaning liquid to flow down, but also form an air outlet blowing towards the top and the circumferential side wall of the sewage tank 10 when the transition member 60 rotates. The fan blade portions can also be provided on the inner surface of the transition main body 61 and extend outwards beyond the circumferential edge of the transition main body 61 to form an air outlet blowing towards the circumferential side wall of the sewage tank 10 when the transition member 60 rotates.

[0044] The cleaning liquid in the liquid storage flow channel 21 flows out from its outlet, and the cleaning liquid flows along the outer surface of the transition main body 61 to the flanging portion 62 and is stored at the flanging portion 62 for a short time. When the transition member 60 rotates relative to the support member 50, the cleaning liquid stored at the flanging portion 62 will be sprayed out from the liquid outlet 63. By using the rotational power of the transition member 60, the cleaning liquid will be sprayed on the circumferential inner wall of the sewage tank 10 to wash down the residual dirt on the inner wall of the sewage tank 10, realizing the cleaning of the sewage tank 10.

[0045] In this embodiment, the liquid storage flow channel 21 includes a cleaning main pipe 211 and a plurality of cleaning branch pipes 212, and the plurality of cleaning branch pipes 212 are connected to the outlet of the cleaning main pipe 211.

[0046] The cleaning main pipe 211 of this embodiment is fixedly arranged through the bottom of the sewage tank 10, and the inlet of the cleaning main pipe 211 is used to communicate with the cleaning tank. The connection portion of the cleaning main pipe 211 near the connection of the cleaning branch pipes 212 is fixedly connected to the connection portion 52 to realize the assembly of the support member 50 and the liquid storage flow channel 21. The cleaning branch pipe 212 includes an extension portion 2121 and a bending portion 2122 connected to the extension portion 2121. The extension portion 2121 is communicated with the outlet of the cleaning main pipe 211, the bending portion 2122 is bent and connected to the end of the extension portion 2121, and the end of the bending portion 2122 extends outwards beyond the outer surface of the transition member 60 so that the outlet of the cleaning branch pipe 212 corresponds to the outer surface of the transition member 60.

[0047] A plurality of cleaning branch pipes 212 are arranged at intervals along the circumferential direction of the cleaning main pipe 211, and the outlet of each cleaning branch pipe 212 can correspondingly flow out the cleaning liquid along the outer surface of the transition member 60. This setting can improve the liquid outlet efficiency of the liquid storage flow channel 21, enable the cleaning liquid to cover the outer surface of the transition member 60, and enhance the cleaning effect of the cleaning liquid on the inside of the sewage tank 10.

[0048] In this embodiment, the transition main body 61 of the transition member 60 is arranged in an umbrella-like structure, which can not only reduce the air resistance when the transition member 60 rotates, but also ensure that the cleaning liquid flows towards the liquid outlet 63 along the trend, thereby improving the cleaning efficiency of the sewage tank 10. It can be understood that in addition to the umbrella-like structure shown in this embodiment, the transition member 60 can also be in a disc shape, a conical shape, etc., as long as the outer surface of the transition member 60 can receive the cleaning liquid and the cleaning liquid can be ejected from the liquid outlet 63 when the transition member 60 is driven.

[0049] The cleaning assembly 20 of this embodiment further includes a driving motor 70, and the driving motor 70 includes a motor main body 71 and a driving rotating shaft 72 connected to the motor main body 71.

[0050] Among them, the motor main body 71 is fixed on the connecting portion 52, and the driving rotating shaft 72 is connected to the inner wall of the transition member 60. When the driving motor 70 works, the driving rotating shaft 72 rotates relative to the motor main body 71, so that the whole transition member 60 rotates relative to the support member 50. In Figure 2 the view direction, the axis direction of the rotation of the transition member 60 is consistent with the vertical direction.

[0051] By controlling the driving motor 70, the rotation speed of the transition member 60 can be adjusted. If there is more dirt inside the sewage tank 10, the rotation speed of the transition member 60 can be increased by regulating the driving motor 70, so as to increase the ejection rate of the cleaning liquid from the liquid outlet 63, thereby enhancing the cleaning effect of the cleaning liquid on the inside of the sewage tank 10.

[0052] In this embodiment, the end of the outlet of the sewage pipe 40 extends below the support member 50, and the outlet of the sewage pipe 40 faces the inner surface of the support main body 51. This setting makes it so that when extracting sewage, the sewage only impacts on the inner surface of the support main body 51 when ejected from the sewage pipe 40, avoiding covering the entire circumferential side wall of the sewage tank 10 with sewage.

[0053] At the same time, in this embodiment, the support main body 51 is arranged in an umbrella-like structure, which can enable the inner surface of the support main body 51 to withstand the impact of the sewage ejected from the sewage pipe 40, and make the sewage flow down along the inner surface of the support main body 51 along the trend, avoiding splashing onto the inner side wall of the sewage tank 10, preventing the sewage from causing large-area pollution in the sewage tank 10, and facilitating the subsequent cleaning of the sewage tank 10.

[0054] It can be understood that, in addition to the umbrella-shaped structure shown in this embodiment, the support body 51 can also be set to a conical shape, a hemispherical shape, etc., as long as it can form a stop surface for sewage on the inner surface of the support body 51 and enable the sewage to flow down along the inner surface of the support body 51 smoothly.

[0055] The periphery of the outlet of the sewage pipe 40 bends towards the outside of the sewage pipe 40, so that the end of the outlet of the sewage pipe 40 forms a structure similar to a flower shape. This setting can reduce the impact force of the sewage ejected from the outlet of the sewage pipe 40, avoid damaging the support member 50 and the transition member 60 when the sewage is ejected, and ensure the integrity of the overall structure of the cleaning assembly 20.

[0056] In this embodiment, in addition to the liquid storage flow channel 21 and the sewage pipe 40, a wire duct 80 is also provided inside the sewage tank 10. The wire duct 80 is arranged in parallel with the clean water pipe and the sewage pipe 40. The inside of the wire duct 80 is used for routing the wires of the relevant components in the cleaning assembly 20, avoiding contact with the cleaning liquid and sewage, preventing water ingress and electric leakage, and ensuring the safety of the cleaning base station 100.

[0057] Furthermore, the cleaning base station 100 further includes a sewage discharge pipe 91. The sewage discharge pipe 91 is arranged outside the sewage tank 10, and the inlet of the sewage discharge pipe 91 is communicated with the accommodating cavity 11 of the sewage tank 10. Through the sewage discharge pipe 91, the sewage in the sewage tank 10 can be discharged. After the sewage in the sewage tank 10 is discharged, the inside of the sewage tank 10 can be cleaned by the cleaning assembly 20. The connection part of the sewage discharge pipe 91 and the sewage tank 10 is arranged close to the bottom of the sewage tank 10 to facilitate the discharge of the sewage in the sewage tank 10.

[0058] In this embodiment, the cleaning base station 100 further includes a control unit. The control unit includes a controller and a concentration detection sensor 92. The concentration detection sensor 92 is arranged on the sewage discharge pipe 91 and is used to measure the concentration of the sewage in the sewage discharge pipe 91. The sewage discharge pipe 91 of this embodiment includes a main sewage discharge pipe 911 and a detection branch pipe 912. The main sewage discharge pipe 911 is communicated with the sewage tank 10, and the detection branch pipe 912 is communicated with the main sewage discharge pipe 911. The sewage flowing in the main sewage discharge pipe 911 can be diverted to the detection branch pipe 912 from the connection part of the detection branch pipe 912 and the main sewage discharge pipe 911.

[0059] The concentration detection sensor 92 is arranged on the detection branch pipe 912. By detecting the concentration of the sewage in the detection branch pipe 912, the concentration of the sewage in the sewage tank 10 can be reflected. It can be understood that the sewage discharge pipe 91 of this embodiment can be directly set to a single-pipe structure without setting a branch pipe, and the concentration detection sensor 92 can be directly arranged on the flow path of the sewage discharge pipe 91.

[0060] In this embodiment, the controller is electrically connected to the concentration detection sensor 92 to receive the concentration signal transmitted by the concentration detection sensor 92. The controller performs data processing accordingly based on the received concentration signal, and then performs corresponding control based on the result of the data processing.

[0061] Specifically, the controller of this embodiment is electrically connected to the drive motor 70. The controller can control the rotation speed of the drive shaft 72 in the drive motor 70 according to the concentration signal transmitted by the concentration detection sensor 92, so as to control the rotation speed of the transition member 60. At the same time, the controller is also electrically connected to the drive pump on the liquid storage flow channel 21. The controller can control the amount of cleaning liquid pumped into the liquid storage flow channel 21 by the drive pump according to the concentration signal transmitted by the concentration detection sensor 92, so as to control the inflow amount of the cleaning liquid into the sewage tank 10.

[0062] When the cleaning base station 100 of this embodiment is actually in use, the cleaning robot enters the cleaning tank 30, and the clean water in the cleaning tank 30 cleans the mopping member of the cleaning robot, and correspondingly generates sewage in the cleaning tank 30. After the mopping member is cleaned, through the power pump on the sewage pipe 40, the sewage in the cleaning tank 30 enters the sewage tank 10 through the sewage pipe 40.

[0063] The sewage is ejected from the outlet of the sewage pipe 40 and directly impacts on the inner surface of the support main body 51. The sewage flows down along the inner surface of the support main body 51, avoiding polluting the entire peripheral side wall of the sewage tank 10. After the sewage is completely extracted from the cleaning tank 30, the sewage discharge pipe 91 is opened to discharge the sewage in the sewage tank 10 through the sewage discharge pipe 91.

[0064] During the process of discharging the sewage through the sewage discharge pipe 91, the concentration detection sensor 92 on the sewage pipe 40 can detect the concentration of the sewage and transmit the sewage concentration signal to the controller. After the sewage in the sewage tank 10 is discharged by the sewage pipe 40, it is necessary to clean the inside of the sewage tank 10.

[0065] The cleaning assembly 20 works, the drive pump is started, and the cleaning liquid enters the sewage tank 10 from the liquid storage flow channel 21. The cleaning liquid flows out from the outlet of the liquid storage flow channel 21, flows along the outer surface of the transition main body 61 to the flanging part 62, and is stored at the flanging part 62 for a short time. The drive motor 70 works, and the transition member 60 rotates relative to the support member 50, and the cleaning liquid stored at the flanging part 62 will be ejected from the liquid outlet 63. Using the rotational power of the transition member 60, the cleaning liquid will be sprayed on the peripheral inner wall of the sewage tank 10 to wash down the residual dirt on the inner wall of the sewage tank 10, realizing the cleaning of the sewage tank 10.

[0066] The controller processes the concentration signal transmitted by the concentration detection sensor 92, and accordingly controls the rotation speed of the driving rotating shaft 72 of the driving motor 70 and the amount of cleaning liquid pumped into the liquid storage channel 21 by the driving pump. Specifically, when the controller analyzes that the sewage concentration is strong, it can increase the amount of cleaning liquid pumped into the liquid storage channel 21 by the driving pump and increase the rotation speed of the driving shaft, so as to increase the rotation speed of the transition part 60, so that a large amount of cleaning liquid quickly impacts the inner wall of the sewage tank 10, thereby flushing the dirt inside the sewage tank 10.

[0067] During the process of the cleaning assembly 20 cleaning the sewage tank 10, the sewage in the sewage tank 10 is discharged through the sewage discharge pipe 91. At this time, the concentration detection sensor 92 continuously detects the concentration of the sewage, so that the controller correspondingly adjusts the amount of cleaning liquid and the rotation speed of the transition part 60. Until the concentration detection sensor 92 detects that the concentration of the sewage is low, the driving pump can be turned off to stop the liquid inlet of the cleaning liquid pipe.

[0068] After turning off the driving pump, the working state of the driving motor 70 can be maintained for several minutes, so that the transition part 60 rotates continuously for several minutes. At this time, the rotation of the transition part 60 drives the air circulation inside the sewage tank 10, and at the same time, the liquid outlet 63 of the transition part 60 can blow out flowing air to air-dry the cleaned sewage tank 10, so as to achieve the effect of clean and dry inside the sewage tank 10.

[0069] In addition, an embodiment of the present application further provides a robot cleaning system, which includes a cleaning robot and the above-mentioned cleaning base station 100.

[0070] Among them, the cleaning robot can be a commercial cleaning robot or a household cleaning robot. Specifically, it can be an autonomous cleaning device such as a floor sweeping robot, a floor mopping robot, a floor washing robot, a sweeping and mopping integrated machine, or a semi-automatic cleaning device such as a hand-held type.

[0071] In addition to being able to clean the mopping part of the cleaning robot and effectively treat the generated sewage as shown above, the cleaning base station 100 can also perform operations such as charging, dust collection, and maintenance of the cleaning robot.

[0072] For the cleaning base station and the robot cleaning system of this embodiment, a cleaning assembly is provided inside the sewage tank of the cleaning base station, and the liquid storage channel of the cleaning assembly is communicated with the accommodating cavity of the sewage tank. The cleaning liquid flows inside the liquid storage channel for cleaning the inside of the sewage tank. Compared with the existing manual cleaning of the sewage tank, this cleaning assembly is more automated and can avoid the manual participation of the user. On the premise of ensuring the user's hygiene, it can also improve the cleaning efficiency of the sewage tank.

[0073] While the invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but rather should be broadly construed within the spirit and scope defined by the appended claims, and thus all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
