Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household cleaning equipment, in particular to a base station for a cleaning machine. BACKGROUND

[0002] The base station is used for charging or cleaning the cleaning robot, for example, the Chinese utility model patent "Base station of cleaning equipment" with the patent number ZL201920524321.X (the authorized announcement number CN210493961U). The chassis of the traditional base station is generally a fixed component, for example, the Chinese utility model patent "Cleaning base station" with the patent number ZL202120543961.2 (the authorized announcement number CN215534017U), the Chinese utility model patent "Base station for cleaning machine and cleaning machine system" with the patent number ZL202120142426.6 (the authorized announcement number CN215502811U). The fixed chassis of the traditional base station will cause the following problems:

[0003] (1) The chassis of the base station is generally designed as a slope, and the cleaning robot is prone to skidding when entering or leaving the base station.

[0004] (2) Since the cleaning tank on the fixed chassis is a fixed tank structure, residual water will remain in the cleaning tank after self-cleaning. If the residual water amount cannot be effectively controlled, too much residual water will cause the residual water to be unable to be quickly dried or quickly disposed of, resulting in mildew and odor.

[0005] (3) In order to ensure that the robot can smoothly enter the base station, the cleaning tank generally cannot be too deep, and the shallow cleaning tank will cause liquid splashing during self-cleaning of the rolling brush, thereby causing secondary pollution to other parts of the base station and affecting the user's experience.

[0006] (4) Additional devices for drying residual water (generally through a fan combined with a drying means of heating) need to be added, which will increase the production cost, and the internal installation space of the base is limited, the added components will affect the internal installation space, and the drying effect is usually not ideal.

[0039] The present application will be further described in detail below with reference to the embodiments of the drawings.

[0040] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, since the disclosed embodiments of the present application can be arranged in different directions, so these orientation-indicating terms are only illustrative and should not be regarded as limiting, such as "upper", "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity. In addition, the features defined as "first", "second" can be explicitly or implicitly included one or more features.

[0041] As Figures 1-6 The preferred embodiment of the base station in the present application is shown, which is suitable for a cleaning system, in particular for cleaning robot back flushing or self-cleaning of the cleaning system. In this embodiment, specifically, the cleaning robot described above is a sweeping robot.

[0042] Further, the base station in the present application includes a chassis 1, which includes a belt 11, a driving shaft 12, a driven shaft 13, a fixed shaft 14 and a movable shaft 15. Wherein, the belt 11 is used to support the cleaning robot of the cleaning system, which is in a closed loop shape and arranged along the direction of the cleaning robot entering and exiting the base station. The driving shaft 12 is supported at one end of the belt 11 along the width direction of the belt 11 and can rotate around its own axis, thereby driving the belt 11 to travel back and forth along the direction of the cleaning robot entering and exiting the base station with the driving shaft 12 as the center. The driven shaft 13 is arranged parallel to the driving shaft 12 and supported at the other end of the belt 11, and can rotate around its own axis under the driving of the belt 11. The fixed shaft 14 is arranged parallel to the driving shaft 12 between the driving shaft 12 and the driven shaft 13, and is fixedly supported on one side of the belt 11 relative to the driving shaft 12 and the driven shaft 13. The movable shaft 15 is arranged parallel to the fixed shaft 14 upward and downward, and is movably supported on the other side of the belt 11 relative to the driving shaft 12 and the driven shaft 13, and can move upward and downward relative to the fixed shaft 14. In this embodiment, the fixed shaft 14 is located above the movable shaft 15.

[0043] Further, in the process of the cleaning robot entering and exiting the base station, the distance between the movable shaft 15 and the fixed shaft 14 is the largest, the strip 11 is in a tension state, and the strip 11 is flatly tensioned between the driving shaft 12 and the driven shaft 13 relative to the upper layer of the driving shaft 12 and the driven shaft 13, and the driving shaft 12 rotates. In the state that the cleaning robot enters the position, the driving shaft 12 stops rotating, the movable shaft 15 moves to make the distance between the movable shaft 15 and the fixed shaft 14 the smallest, and one end of the strip 11 relative to the upper layer of the driving shaft 12 and the driven shaft 13 is recessed downward along the width direction of the strip 11 to form a first groove 111, and the first groove 111 is configured as a cleaning tank 2 in the base station.

[0044] As can be seen from the above, the base station of the present application includes the strip 11, the driving shaft 12, the driven shaft 13, the fixed shaft 14 and the movable shaft 15, wherein the strip 11 is stably supported by the driving shaft 12, the driven shaft 13, the fixed shaft 14 and the movable shaft 15, thereby realizing the stable support of the strip 11 to the cleaning robot. Further, the strip 11 can travel back and forth along the direction of the cleaning robot entering and exiting the base station around the driving shaft 12 under the driving of the driving shaft 12, thereby conveying the cleaning robot to enter and exit the base station, ensuring the cleaning robot to better enter and exit the base station, avoiding the phenomenon of slipping of the cleaning robot when entering and exiting the base station, and the position of the cleaning robot can be finely adjusted by the travel of the strip 11, thereby better ensuring the docking success rate of the docking mechanism of the cleaning robot and the base station. Further, in the state that the cleaning robot enters the position, the cleaning tank 2 is configured in the base station by forming the first groove 111 on the strip 11, so that after the cleaning robot is cleaned, the first groove 111 can be flattened again by the action of the movable shaft 15 (i.e., for the preparation of the cleaning robot exiting the base station), so that the residual water in the cleaning tank 2 flows out, avoiding the residual water in the cleaning tank 2, and after being flattened, it is beneficial to the cleaning and drying of the strip 11 at the position of the first groove 111, without the need to additionally set a device for air-drying the residual water in the cleaning tank 2. Further, since the first groove 111 is a movable structure (i.e., the first groove 111 can be flattened again when the cleaning robot enters and exits the base station), the cleaning tank 2 in the present application can be deep enough (i.e., the first groove 111 is recessed deep enough), thereby avoiding the liquid splashing when the cleaning robot is cleaned, and effectively avoiding the secondary pollution of the base station.

[0045] Further, in the state that the cleaning robot is in place, the strip 11 under the rolling brush of the cleaning robot is concave downward under the gravity of the cleaning robot to form the first groove 111. Thus, the fit of the formed cleaning groove 2 and the rolling brush of the cleaning robot is improved, which is beneficial to improve the self-cleaning effect. Preferably, the strip 11 is arranged obliquely relative to the horizontal plane, and the driving shaft 12 is higher than the driven shaft 13, and in the state that the cleaning robot is in place, the strip 11 is concave downward relative to the upper end of the driving shaft 12 and the driven shaft 13 to form the first groove 111. In this way, the gravity center of the cleaning robot is lowered, and the cleaning robot can better form the cleaning groove 2 under its own gravity when it is in place, and the formed cleaning groove 2 can be more fitted with the rolling brush of the cleaning robot.

[0046] Further, the strip 11 is provided with a first feature 112 for colliding with the front end of the cleaning robot, and in the initial state that the cleaning robot enters the base station, the first feature 112 is adjacent to the driven shaft 13, and in the state that the cleaning robot is in place, the first feature 112 is adjacent to the driving shaft 12. The relative position of the strip 11 and the cleaning robot can be monitored through the first feature 112, so that the cleaning robot can be better ensured to be in place, and the accurate docking of the cleaning robot can be better ensured. Preferably, in the embodiment, the first feature 112 is a protruding rib protruding on the outer surface of the strip 11, and the protruding rib extends along the width direction of the strip 11. Thus, the first feature 112 has a simple structure, and can limit the position of the cleaning robot, so that the cleaning robot can be better ensured to be in place.

[0047] Further, the base plate 1 in the application further comprises an elastic member 4 and a limiting member 5, wherein the elastic member 4 is arranged between the fixed shaft 14 and the movable shaft 15 along the moving direction of the movable shaft 15. During the process that the cleaning robot enters the base station, the elastic member 4 is in the initial state and limits the movable shaft 15, and in the state that the cleaning robot is in place, the elastic member 4 is contracted to make the movable shaft 15 have a tendency to move away from the fixed shaft 14 to return to the initial state, and the limiting member 5 limits the movable shaft 15. Thus, the movable shaft 15 can be switched between the two states, and can be stably maintained in each state, so that the stability of the structure of the strip 11 in the two states is ensured, and then the cleaning robot can smoothly enter and exit the base station, and the orderly performance of the self-cleaning process of the cleaning robot can be ensured.

[0048] Further, the base 1 further comprises a wedge-shaped base 3, which is hollow and open at the top, and the strip 11 is shielded in the opening of the base 3. In the state that the cleaning robot is in place, the first groove 111 on the strip 11 is surrounded by the left and right side walls of the base 3 to form the cleaning tank 2. Thus, when the strip 11 is concave to form the first groove 111, the cleaning tank 2 is formed in the base station, which not only facilitates the construction of the cleaning tank 2 in the base station, but also facilitates the flattening of the strip 11 after cleaning.

[0049] Further, the left and right side walls of the base 3 are respectively provided with shaft holes 31 for inserting the corresponding ends of the driving shaft 12, the driven shaft 13 and the fixed shaft 14. There are also sliding holes 32 for the corresponding ends of the movable shaft 15 to slide back and forth, and the upper ends of the hole rims of each sliding hole 32 are respectively provided with a first mounting column 51, and the two ends of the movable shaft 15 are respectively provided with a second mounting column 52. The elastic member 4 is two and corresponds to the sliding hole 32, each elastic member 4 is a spring installed in the corresponding sliding hole 32, and one end of each spring is connected to the first mounting column 51 of the corresponding sliding hole 32, and the other end is connected to the second mounting column 52 of the corresponding end of the movable shaft 15. During the process of the cleaning robot entering and exiting the base station, the two ends of the movable shaft 15 respectively abut the lower ends of the hole rims of the corresponding sliding hole 32. Thus, the driving shaft 12, the driven shaft 13 and the fixed shaft 14 can be stably installed, and during the process of the cleaning robot entering and exiting the base station, the two ends of the movable shaft 15 are located at the lower ends of the corresponding sliding hole 32, and the two ends of the movable shaft 15 are positioned by the elastic force of the corresponding elastic member 4.

[0050] Further, the left and right side walls of the base 3 are respectively provided with a limiting groove 33 on one side of the corresponding sliding hole 32, which opens towards the sliding hole 32. The limiting member 5 is two and corresponds to the limiting groove 33, and each limiting member 5 is a block body accommodated in the corresponding limiting groove 33, and one end of each block body respectively protrudes out of the opening of the limiting groove 33. In the state that the cleaning robot is in place, each limiting member 5 abuts the corresponding end of the movable shaft 15. Thus, the movable shaft 15 can be positioned more stably, and the strip 11 can be better maintained in the state that the cleaning robot is in place.

[0051] In addition, the base 1 further comprises a motor 6 for driving the rotation of the driving shaft 12, and the outer side of one side of the base 3 is provided with a motor seat 7 for installing the motor 6. Furthermore, the radius of the driving shaft 12 is greater than that of the driven shaft 13, and the radii of the fixed shaft 14 and the movable shaft 15 are equal and smaller than that of the driven shaft 13. Thus, the strip 11 can travel more smoothly, which is conducive to ensuring the stability of the cleaning robot entering and exiting the base station.
