When the battery is low, the cleaning robot can automatically return to the base station for charging. In addition, the base station can also provide functions such as dust collection and water replenishment to further free your hands.

[0004] However, in the related art, the cleaning robot is prone to leaking water when returning to the base station for water replenishment, and the leaked water is easy to enter the base station, resulting in a technical problem of low safety and reliability when the base station charges the cleaning robot. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a base station and a cleaning system, which can avoid the problem of water leakage when the cleaning equipment returns to the base station for water replenishment, thereby improving the safety and reliability of the cleaning equipment when charging on the base station.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a base station, which is suitable for docking cleaning equipment, comprising: a main body, a water replenishment structure and a charging structure, wherein the water replenishment structure and the charging structure are arranged on the main body; the water replenishment structure has a water replenishment port, and the cleaning equipment has an openable and closable water inlet; the charging structure has a charging female terminal, and the cleaning equipment has a charging sub-terminal; a first matching plane is formed at the position where the water replenishment port and the water inlet are sealed and connected, and a second matching plane is formed at the position where the charging female terminal and the charging sub-terminal are in electrical contact, and there is a vertical spacing between the first matching plane and the second matching plane, and the first matching plane is located above the second matching, so that when the cleaning equipment docks at the base station, after the water inlet and the water replenishment port are sealed and connected, the charging female terminal is electrically connected to the charging sub-terminal.

[0008] In the base station provided in the embodiment of the present application, a height difference is formed in the vertical direction between the first matching plane formed at the position where the water replenishing port and the water inlet are sealed and connected, and the second matching plane formed at the position where the charging female terminal and the charging sub-terminal are in electrical contact, so that the second matching plane is located below the first matching plane. In this way, when the cleaning equipment docks at the base station, the water replenishing port on the base station is sealed and connected to the water inlet on the cleaning equipment, and only then will the charging female terminal and the charging sub-terminal come into contact to achieve electrical connection. In this way, water overflow at the water replenishing port can be avoided to affect the electrical contact between the charging female terminal and the charging sub-terminal, thereby improving the safety and reliability of the cleaning equipment when charging on the base station.

[0009] In some embodiments, a vertical distance between the first matching plane and the second matching plane is greater than or equal to 1 mm.

[0010] This arrangement ensures that the charging female terminal and the charging sub-terminal are electrically contacted and energized only after the water filling port and the water inlet are completely sealed and connected, thereby improving the safety and reliability of the cleaning equipment when charging on the base station.

[0011] In some embodiments, a vertical distance between the first matching plane and the second matching plane is 3.5-5 mm.

[0012] In some embodiments, the cleaning device has a water inlet having the water inlet. When the cleaning device is docked at the base station, the water inlet is at least partially located in the water replenishment port, and the water inlet is sealed and connected to the water replenishment port.

[0013] Such an arrangement improves the reliability of the connection between the water replenishment port and the water inlet, and avoids the problem of water leakage at the connection between the water replenishment port and the water inlet.

[0014] In some embodiments, the invention further includes: a sealing member, wherein the sealing member is disposed between an outer side wall of the water inlet and a side wall of the water replenishment port, and the sealing member is configured to seal a gap between the water inlet and the water replenishment port.

[0015] Such arrangement can improve the sealing performance between the water inlet and the water replenishing port through the sealing member, thereby avoiding the problem of water leakage at the water replenishing port.

[0016] In some embodiments, the base station includes at least two sealing members, and the at least two sealing members are spaced apart between the outer side wall of the water inlet and the side wall of the water replenishment port along the depth direction of the water replenishment port.

[0017] Such an arrangement can further improve the sealing reliability between the water inlet and the water replenishment port, and avoid the problem of water leakage at the water replenishment port.

[0018] In some embodiments, one of the outer side wall of the water inlet and the side wall of the water replenishment port has a mounting position matching the sealing component, and the sealing component is installed on the mounting position.

[0019] Such an arrangement improves the accuracy and reliability of the installation position of the seal, thereby improving the sealing performance at the water supply port.

[0020] In some embodiments, the sealing member is at least one of a sealing ring and a sealing gasket.

[0021] Such arrangement has a simple structure, is easy to implement and has low cost.

[0022] In some embodiments, the water inlet is an elastic structure, and when the water inlet is at least partially located in the water replenishment port, the water inlet and the water replenishment port are interference fit.

[0023] With such arrangement, when the water inlet partially enters the water replenishing port, the side wall of the water inlet and the water replenishing port are interference fit to achieve sealing, without the need for additional sealing components. The structure is simple, easy to implement and low in cost.

[0024] In some embodiments, the water replenishment structure also includes a water injection pipe column, which is arranged in the water inlet. A water inlet valve is provided at the water inlet of the cleaning equipment, and the water injection pipe column is configured to open and close the water inlet valve; when the cleaning equipment is docked at the base station, the water injection pipe column is configured to drive the water inlet valve to open so that the water inlet is connected to the water replenishment port.

[0025] With this arrangement, when the cleaning equipment docks at the base station, the water inlet valve can be automatically opened through the water injection pipe column without the need for manual opening, thereby saving labor costs and improving user experience.

[0055] With the development of science and technology and the improvement of living standards, cleaning equipment such as household cleaning robots have become increasingly popular, reducing the burden of human housework. At present, most cleaning robots on the market are equipped with a multifunctional base station. When the battery is low, the cleaning robot can automatically return to the base station for charging. In addition, the base station can also provide dust collection, water replenishment and other functions to further free your hands. However, in the related art, the cleaning robot is prone to leaking when returning to the base station for water replenishment, and the leaked water is easy to enter the base station, resulting in a technical problem of low safety and reliability when the base station charges the cleaning robot.

[0056] In order to solve the above problems, an embodiment of the present application provides a base station and a cleaning system, wherein a height difference is formed in the vertical direction between a first matching plane formed at the position where the water replenishment port and the water inlet are sealed and connected, and a second matching plane formed at the position where the charging female terminal and the charging sub-terminal are in electrical contact, so that the second matching plane is located below the first matching plane. In this way, when the cleaning equipment docks at the base station, the water replenishment port on the base station and the water inlet on the cleaning equipment will be sealed and connected before the charging female terminal and the charging sub-terminal will contact to achieve electrical connection. In this way, water overflow at the water replenishment port can be avoided to affect the electrical contact between the charging female terminal and the charging sub-terminal, thereby improving the safety and reliability of the cleaning equipment when charging on the base station.

[0057] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0058] Figure 1 A cross-sectional schematic diagram of a base station at a cut position provided in an embodiment of the present application; Figure 2 for Figure 1 A local enlarged schematic diagram of the middle A; Figure 3 A partial cross-sectional schematic diagram of a base station provided in an embodiment of the present application; Figure 4 for Figure 3 A partial enlarged schematic diagram of point B in the middle; Figure 5 Another partial cross-sectional schematic diagram of a base station provided in an embodiment of the present application; Figure 6 for Figure 5 A partial enlarged schematic diagram of point C in the middle.

[0059] Please refer to Figures 1 to 6 As shown, an embodiment of the present application provides a base station 100 suitable for docking a cleaning device 200 . The cleaning device 200 may be an automatic cleaning robot for cleaning, for example, the floor. The embodiment of the present application does not specifically limit the type of the cleaning device 200 .

[0060] The base station 100 provided in the embodiment of the present application includes: a main body 110 and a water replenishment structure 120, the water replenishment structure 120 is arranged on the main body 110; the water replenishment structure 120 has a water replenishment port 121, and the cleaning device 200 has an openable and closable water inlet 210, and the water replenishment port 121 is configured to be connected with the water inlet 210 to replenish water to the cleaning device 200.

[0061] Exemplarily, a water replenishment tank is provided on the main body 110, and the water replenishment port 121 is connected to the water replenishment tank; the cleaning equipment 200 has a clean water tank, and the water inlet 210 is connected to the clean water tank. In this way, when the clean water equipment returns to the base station 100, the water replenishment port 121 is connected to the water inlet 210, so that the water in the water replenishment tank can be replenished into the clean water tank of the cleaning equipment 200 through the connected water replenishment port 121 and the water inlet 210, thereby realizing that the base station 100 has the function of replenishing water to the cleaning equipment 200.

[0062] In some embodiments, the base station 100 also includes a charging structure 130, which is arranged on the base station 100. The charging structure 130 has a charging female terminal 131, and the cleaning device 200 has a charging sub-terminal 240. In this way, when the cleaning device 200 returns to the base station 100, the charging sub-terminal 240 is electrically contacted with the charging female terminal 131 to realize the function of charging the cleaning device 200.

[0063] When the base station 100 replenishes water to the cleaning device 200, water overflow may easily occur at the water replenishment port 121, and the overflowed water may easily enter the interior of the base station 100 and wet, for example, the charging structure 130, thereby affecting the safety and reliability of the base station 100 during charging.

[0064] In response to the above problems, in an embodiment of the present application, a first matching plane 122 is formed at the position where the water replenishment port 121 and the water inlet 210 are sealed and connected, and a second matching plane 132 is formed at the position where the charging female terminal 131 and the charging sub-terminal 240 are in electrical contact. There is a vertical distance between the first matching plane 122 and the second matching plane 132, and the first matching plane 122 is located above the second matching, so that when the cleaning equipment 200 docks at the base station 100, after the water inlet 210 and the water replenishment port 121 are sealed and connected, the charging female terminal 131 and the charging sub-terminal 240 are electrically connected.

[0065] That is to say, in the embodiment of the present application, through the height difference between the water replenishment structure 120 and the charging structure 130, a height difference is formed in the vertical direction between the first matching plane 122 formed at the position where the water replenishment port 121 is sealed and connected to the water inlet 210, and the second matching plane 132 formed at the electrical contact between the charging female terminal 131 and the charging sub-terminal 240, so that the second matching plane 132 is located above the first matching plane 122. In this way, when the cleaning equipment 200 docks at the base station 100, the water replenishment port 121 on the base station 100 is sealed and connected to the water inlet 210 on the cleaning equipment 200, which can avoid water overflowing from the water replenishment port 121. After that, the charging female terminal 131 and the charging sub-terminal 240 will be in contact to achieve electrical connection, thereby avoiding water overflow at the water replenishment port 121 and affecting the electrical contact between the charging female terminal 131 and the charging sub-terminal 240, thereby improving the safety and reliability of the cleaning equipment 200 when charging on the base station 100.

[0066] In some embodiments, please refer to Figure 2 As shown, the vertical spacing between the first matching plane 122 and the second matching plane 132 can be represented by H, and the dimension value of H can be greater than or equal to 1mm. Preferably, the dimension value of H can be 3.5mm to 5mm. Exemplarily, the spacing H between the first matching plane 122 and the second matching plane 132 is 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 3.8mm, 4mm, 4.5mm, 5mm, etc., to ensure that the charging female terminal 131 and the charging sub-terminal 240 are electrically contacted and energized only after the water replenishment port 121 is completely sealed and connected with the water inlet 210, thereby improving the safety and reliability of the cleaning device 200 when charging on the base station 100.

[0067] Exemplarily, the distance between the first matching plane 122 and the second matching plane 132 is the distance in the vertical direction. In this way, when the cleaning device 200 returns to dock at the base station 100, the water replenishment port 121 is first connected and sealed with the water inlet 210 in the cleaning device 200 to prevent water from overflowing from the water replenishment port 121; after the water replenishment port 121 is sealed and connected with the water inlet 210, the charging female terminal 131 is electrically contacted and electrically connected with the charging sub-terminal 240 to charge the cleaning device 200.

[0068] In some embodiments, the water replenishment port 121 is a gap formed on the water replenishment structure 120, and the gap is surrounded to form the water replenishment port 121. The water replenishment port 121 can accommodate a certain amount of liquid. In order to prevent the liquid in the water replenishment port 121 from overflowing outward, the water replenishment port 121 is connected to the water inlet 210 and then sealed, as long as the water overflow at the water replenishment port 121 can be prevented.

[0069] In some embodiments, please refer to Figure 4 As shown, the cleaning device 200 has a water inlet 220. Exemplarily, the water inlet 220 is, for example, a columnar structure. The water inlet 220 has a water inlet 210. When the cleaning device 200 is docked at the base station 100, the water inlet 220 is at least partially located in the water replenishment port 121, and the water inlet 220 is sealed and connected to the water replenishment port 121. In this way, the connectivity reliability between the water replenishment port 121 and the water inlet 210 is improved, and the problem of water leakage at the connection between the water replenishment port 121 and the water inlet 210 is avoided.

[0070] In some embodiments, please refer to Figure 4 As shown, it also includes: a sealing member 140, which is arranged between the outer wall of the water inlet 220 and the side wall of the water replenishment port 121, and the sealing member 140 is configured to seal the gap between the water inlet 220 and the water replenishment port 121. It should be noted that the side wall of the water replenishment port 121 refers to the side wall of the water replenishment port 121 that is surrounded and formed in the water replenishment structure 120. In this way, when the water inlet 220 is at least partially located in the water replenishment port 121, the sealing between the water inlet 220 and the water replenishment port 121 is improved by the sealing member 140, and the side wall of the water inlet 220 is sealed and connected with the side wall of the water replenishment port 121, thereby preventing water from overflowing from the top of the water replenishment port 121.

[0071] In order to further improve the sealing reliability between the water inlet 220 and the water replenishment port 121, in some embodiments, the base station 100 includes at least two seals 140, and the at least two seals 140 are spaced apart along the depth direction of the water replenishment port 121 between the outer wall of the water inlet 220 and the side wall of the water replenishment port 121. In this way, the sealing reliability between the water inlet 220 and the water replenishment port 121 can be further improved, and the problem of water leakage at the water replenishment port 121 can be avoided.

[0072] Exemplarily, the seal 140 can be at least one of a sealing ring and a sealing gasket, that is, the seal 140 seals the gap between the side of the water inlet 220 and the side wall of the water replenishment port 121, wherein the seal 140 can be a rubber ring, a silicone ring, etc. made of rubber, silicone, etc., which has a simple structure, is easy to implement, and has low cost.

[0073] In some embodiments, one of the outer side wall of the water inlet 220 and the side wall of the water replenishment port 121 has a mounting position 221 matching the sealing member 140 , and the sealing member 140 is mounted on the mounting position 221 .

[0074] It can be understood that by setting a mounting position 221 on one of the side walls of the water inlet 220 and the water replenishment port 121, and installing the seal 140 in the mounting position 221, the seal 140 can be positioned to improve the accuracy and reliability of the position of the seal 140, thereby improving the sealing at the water replenishment port 121.

[0075] Exemplarily, the seal 140 is a sealing ring, and the outer wall surface of the water inlet 220 has an annular mounting groove. The sealing ring is sleeved on the water inlet 220 and located in the mounting groove, so as to position and fix the sealing ring. In this way, when at least part of the water inlet 220 is located in the water inlet 210, the sealing ring seals the gap between the outer wall of the water inlet 220 and the side wall of the water inlet 210, avoiding water overflow from the water replenishment port 121, thereby improving the safety and reliability of the cleaning device 200 during charging.

[0076] In other embodiments, the sealing member 140 may not be separately provided, but the water inlet 220 may be an elastic structure. When the water inlet 220 is at least partially located in the water replenishment port 121, the water inlet 220 and the water replenishment port 121 have an interference fit. When the water inlet 220 partially enters the water replenishment port 121, the side wall of the water inlet 220 and the water replenishment port 121 have an interference fit to achieve sealing, that is, there is no gap between the side wall of the water inlet 220 and the side wall of the water replenishment port 121, so that the side wall of the water inlet 220 and the side wall of the water replenishment port 121 can be sealed without the need to additionally provide the sealing member 140 to prevent water from overflowing from the water replenishment port 121. The structure is simple, easy to implement, and low in cost.

[0077] In some embodiments, please refer to Figure 4As shown, the water replenishment structure 120 also includes a water injection column 123, which is arranged in the water inlet 210. The water injection column 123 is, for example, connected to the water replenishment tank. A water inlet valve 230 is arranged at the water inlet 210 of the cleaning device 200, and the water injection column 123 is configured to open and close the water inlet valve 230. When the cleaning device 200 docks at the base station 100, the water injection column 123 is configured to drive the water inlet valve 230 to open, so that the water inlet 210 is connected to the water replenishment port 121. In this way, when the cleaning device 200 docks at the base station 100, the water inlet valve 230 can be automatically opened by the water injection column 123 without manual opening, thereby saving labor costs and improving user experience.

[0078] Exemplarily, the water inlet valve 230 can move in the vertical direction. When the cleaning device 200 leaves the base station 100, the water inlet valve 230 blocks the water inlet 210. When the cleaning device 200 docks at the base station 100, the water injection column 123 pushes the water inlet valve 230 to move upward, so that the water inlet valve 230 opens the water inlet 210, so that the water replenishment port 121 is connected to the water inlet 210. The water in the water replenishment port 121 replenishes the cleaning device 200 from bottom to top under the action of power. The water flow direction is as follows: Figure 4 The direction of the arrow.

[0079] In addition, the cleaning device 200 also includes a first elastic member 250, which is connected between the cleaning device 200 and the water inlet valve 230. When the water replenishment is completed, the water injection pipe column 123 releases the resistance to the water inlet valve 230, and the first elastic member 250 drives the water inlet valve 230 to move downward in the vertical direction under the action of its own elastic force, so that the water inlet valve 230 blocks the water inlet 210, so as to avoid water leakage after the cleaning device 200 leaves the base station 100.

[0080] The first elastic member 250 includes but is not limited to a spring, an elastic pad and other structures, and is not specifically limited thereto.

[0081] In some embodiments, please refer to Figure 6 As shown, the charging female terminal 131 can move in the vertical direction to adapt to the charging sub-terminals 240 of different heights, thereby improving the reliability of the electrical contact between the charging female terminal 131 and the charging sub-terminal 240 .

[0082] Exemplarily, the charging structure 130 also includes a second elastic member 133, which is disposed between the charging female terminal 131 and the main body 110, so that the second elastic member 133 can drive the charging female terminal 131 to move toward one side of the charging sub-terminal 240 through its own elastic force, so as to improve the reliability of the electrical connection between the charging female terminal 131 and the charging sub-terminal 240.

[0083] In some embodiments, the second elastic member 133 includes but is not limited to a spring, an elastic pad, and other structures, which are not specifically limited.

[0084] A second aspect of the embodiments of the present application further provides a cleaning system, comprising: a cleaning device and a base station as provided in the above embodiments, wherein the cleaning device is configured to dock at the base station.

[0085] The structure and working principle of the base station may refer to the above embodiments and will not be described in detail here.

[0086] In addition, the cleaning equipment may refer to the structure of the related technology and is not limited here.

[0087] The base station and the cleaning system provided in the embodiments of the present application form a height difference in the vertical direction between the first matching plane formed at the position where the water filling port and the water inlet are sealed and connected, and the second matching plane formed at the electrical contact between the charging female terminal and the charging sub-terminal, so that the second matching plane is located below the first matching plane. In this way, when the cleaning equipment docks at the base station, the water filling port on the base station and the water inlet on the cleaning equipment are sealed and connected, and then the charging female terminal and the charging sub-terminal will contact to achieve electrical connection. In this way, water overflow at the water filling port can be avoided to affect the electrical contact between the charging female terminal and the charging sub-terminal, thereby improving the safety and reliability of the cleaning equipment when charging on the base station.
