[0002] In recent years, with the popularization of automatic cleaning equipment, the functions of automatic cleaning equipment have become more and more, especially the application of automatic cleaning equipment that integrates multiple functions such as sweeping, vacuuming, mopping, dust removal, and mop cleaning has become more and more common.

[0003] In the prior art, clean water is added to the automatic cleaning device through the clean water tank of the base station. When the automatic cleaning device runs to the designated position of the base station, the base station is connected to the automatic cleaning device through a docking assembly.

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Based on this, this embodiment provides a passive base station for a cleaning robot and a cleaning robot adapted therewith, which can be described in detail through specific embodiments below:

[0034] Reference Figure 1 , 7 As shown, a passive base station 1 for a cleaning robot 2 provided in this embodiment includes a filling module, wherein the filling module includes a clean water tank 11 and a clean water docking assembly 12, the clean water tank 11 is provided with a water inlet 111 and a water outlet 112, the water inlet 111 is used to connect to an external water source, and the water outlet 112 is docked with the cleaning robot 2 through the clean water docking assembly 12, so that the clean water in the clean water tank 11 can flow to the cleaning robot 2, the filling module also includes a passive self-driving assembly 13, the passive self-driving assembly 13 includes a float assembly, the float assembly can adapt to the change of the water level height of the clean water tank 11 and move by itself, so that the float assembly includes a first state and a second state, wherein, in the first state, the float assembly closes the water inlet 111, so that clean water cannot flow into the clean water tank 11 from the external water source; in the second state, the float assembly opens the water inlet 111, so that clean water can flow into the clean water tank 11 from the external water source.

[0035] The passive base station 1 for the cleaning robot 2 provided in this embodiment can utilize the buoyancy of the clean water in the clean water tank 11 to control the height of the float assembly and close the water inlet 111 through the setting of the passive self-driven component 13, so that the passive base station 1 can complete the work of injecting water into the cleaning robot 2 and quantitatively storing water without the need for an external power source. The passive base station 1 only needs an external water source to ensure that the amount of water in the clean water tank 11 is always maintained within a preset range. In other words, the passive base station 1 is not restricted by the location of the power supply, which improves the flexibility of the passive base station 1, so that the passive base station 1 only needs to be set in a location with an external water source such as a bathroom, kitchen, balcony, etc., so as to make it more convenient to rationally arrange the working route and working environment of the cleaning robot 2; and this passive self-driven method has no electronic components, simplifies the structure and reduces costs, and can also reduce the failure rate of the passive base station 1, making the work more reliable.

[0036] Continue to refer to Figures 2 to 4 As shown, the second state is generally when the water outlet 112 is opened, and the clean water tank 11 injects clean water into the cleaning robot 2, causing the water level in the clean water tank 11 to decrease. The first state is generally when the water outlet 112 is closed, and the water level in the clean water tank 11 does not meet the preset requirement. At this time, the water inlet 111 is in an open state, causing the water level in the clean water tank 11 to increase. When the water inlet speed of the water inlet 111 is greater than the water outlet speed of the water outlet 112, when the water outlet 112 is opened, the water level in the clean water tank 11 can also be increased in the first state.

[0037] In some embodiments, the float assembly includes a floating block 131, wherein the floating block 131 can float up and down to adapt to the change of the water level of the clean water tank 11, so that the floating block 131 can close or open the water inlet 111; specifically, the floating block 131 can be a structure with a density lower than that of the clean water, ensuring that the floating block 131 always at least partially leaks out of the water surface and can move itself following the change of the water level of the clean water; the floating block 131 can specifically be a plastic ball filled with air, or other foam, plastic or other structures.

[0038] In a further embodiment, a track 134 for limiting the horizontal movement of the floating block 131 may be provided in the clean water tank 11, the track 134 extends in the height direction, and the floating block 131 floats up and down along the extension direction of the track 134, wherein the water inlet 111 is located in the track 134. By setting the track 134, it can be ensured that the floating block 131 can accurately block the water inlet 111 when following the rise of the water surface, and will not shake in the horizontal direction, thereby affecting the sealing effect of the water inlet 111.

[0039] Continue to refer to Figures 2 to 4As shown, the float assembly also includes an abutment block 133 and a connecting rod 132, the connecting rod 132 has a rotating portion, the connecting rod 132 is rotatably connected to the clean water tank 11 through the rotating portion, the first end of the connecting rod 132 is connected to the floating block 131, and the second end of the connecting rod 132 is connected to the abutment block 133; when the float assembly switches from the second state to the first state, the floating block 131 floats up with the rise of the water surface of the clean water tank 11, so that the abutment block 133 descends with the rise of the water surface of the clean water tank 11 until the abutment block 133 abuts against the water inlet 111; and / or, when the float assembly switches from the first state to the second state, the floating block 131 descends with the drop of the water surface of the clean water tank 11, so that the abutment block 133 descends with the drop of the water surface of the clean water tank 11 It descends and rises until the abutment block 133 is separated from the water inlet 111; it should be understood that since the floating block 131 is connected to the first end of the connecting rod 132, when the water level in the clean water tank 11 is too low, the floating block 131 may be separated from the water surface and cannot continue to follow the water level to descend. At this time, the abutment block 133 is also above the water inlet 111. At this time, water can enter the water inlet 111 without affecting the normal operation of the clean water tank 11; through the arrangement of the connecting rod 132 and the abutment block 133, a lever principle can be formed, and the distance between the floating block 131 and the rotating part can be greater than the distance between the abutment block 133 and the rotating part, thereby amplifying the buoyancy of the water and increasing the pressure of the abutment block 133 to block the water inlet 111.

[0040] It should be noted that when the float assembly switches from the second state to the first state, clean water flows into the clean water tank 11 from the external water source through the water inlet 111, so that the water level of the clean water tank 11 has an upward trend; and / or, when the float assembly switches from the first state to the second state, the clean water in the clean water tank 11 is injected into the cleaning robot 2 through the clean water docking assembly 12, so that the water level of the clean water tank 11 has a downward trend; it should be understood that when the amount of clean water in the clean water tank 11 reaches the preset requirement, the abutment block 133 blocks the water inlet 111, and the float assembly is in the first state at this time; when the water outlet 112 is opened, the water level in the clean water tank 11 drops, and this is the switching from the first state to the second state. Due to the drop in water level, the floating block 131 also begins to drop, and the abutment block 133 begins to lose the pressure on the water inlet 111 and moves away from the water inlet 111. The water inlet 111 begins to open. If the water inlet speed of the water inlet 111 is greater than the water outlet speed of the water outlet 112, the water level in the clean water tank 11 will soon rise to the preset requirement again, so that the abutment block 133 will block the water inlet 111 again, and so on. When the water outlet 112 is closed, the abutment block 133 will block and open the water inlet 111 many times. If the water inlet speed of the water inlet 111 is less than the water outlet speed of the water outlet 112, the water level in the clean water tank 11 will only continue to drop when the water outlet 112 is open, until the water outlet 112 is closed, and the water level in the clean water tank 11 will gradually rise to the preset requirement, and at this time the second state switches to the first state; it should be understood that the water outlet speed of the water outlet 112 should be set to be greater than the water inlet speed of the water inlet 111, so as to protect the float assembly and the water inlet 111 and increase the service life of the base station.

[0041] In some embodiments, the clean water base station may further include a motion guide component 14, which is used to guide the cleaning robot 2 when it is preparing to dock with the clean water base station to collect water, so that the cleaning robot 2 is adjusted to move directly toward the clean water docking component 12 before it is fully docked with the clean water base station; specifically, the motion guide component 14 may include a protruding structure 141 that extends out from the docking position of the cleaning robot 2 and is arranged on the clean water base station, and a groove structure 142 that is arranged on the cleaning robot 2 and is concave-convexly matched with the protruding structure 141, thereby achieving a guiding effect before the cleaning robot 2 is fully docked with the clean water docking component 12.

[0042] Continue to refer to Figure 1 , Figure 2 and Figure 7As shown, the clean water base station also includes a positioning detection point 15, which is used for the cleaning robot 2 to detect whether it has moved into position; when the cleaning robot 2 has moved into position, that is, when the clean water box 21 is fully docked with the clean water docking assembly 12, the sensor on the cleaning robot 2 can detect the corresponding positioning detection point 15, and then open the water outlet 112 of the clean water base station to discharge water. This setting can avoid the situation where the water outlet 112 is opened by the water injection drive 22 before the cleaning robot 2 is fully docked with the clean water docking assembly 12, thereby causing pollution to the clean water base station and the cleaning robot 2 itself; the positioning detection point 15 can also be used to guide the route of the cleaning robot 2, so as to further improve the efficiency of the docking of the cleaning robot 2 with the clean water base station.

[0043] In some embodiments, the float assembly is used to open or close the water inlet 111. When the amount of clean water in the clean water tank 11 meets the preset requirements, the float assembly closes the water inlet 111, wherein the preset requirement for the amount of clean water in the clean water tank 11 is not less than the maximum clean water storage capacity of the cleaning robot 2; that is, the amount of clean water in the clean water tank 11 can at least meet the need to completely fill the clean water box 21 of the cleaning robot 2 with clean water once.

[0044] Furthermore, the preset requirement for the amount of clean water in the clean water tank 11 is not less than the sum of the maximum clean water storage capacity of the cleaning robot 2 and the amount of clean water required for the cleaning robot 2 to complete a single self-cleaning task; that is, when the amount of clean water in the clean water box 21 of the cleaning robot 2 is 0, it can first go to the clean water base station to add water to the amount of clean water required to complete a self-cleaning, and then perform self-cleaning. After completing self-cleaning, it can immediately reconnect with the clean water tank 11 to complete the complete filling of the clean water box 21 with clean water; thereby significantly improving the water replenishment efficiency of the cleaning robot 2 and avoiding the situation where the cleaning robot 2 waits for the clean water tank 11 to be replenished at the clean water base station.

[0045] Specifically, the preset requirement for the amount of clean water in the clean water tank 11 can be the sum of the maximum clean water storage capacity of the cleaning robot 2 and the amount of clean water required for the cleaning robot 2 to complete a single self-cleaning task; for example, when the maximum clean water storage capacity of the clean water box 21 is 280ml and the water consumption of the cleaning robot 2 for self-cleaning is 220ml, the preset requirement for the amount of clean water in the clean water tank 11 can be 500ml, thereby ensuring that one water filling operation in the clean water tank 11 can complete the self-cleaning of the cleaning robot 2 and the total water consumption for cleaning the floor.

[0046] In some embodiments, when the amount of clean water in the clean water tank 11 reaches a preset requirement, the water surface in the clean water tank 11 should have a certain distance from the top cover of the clean water tank 11, so as to ensure that when the clean water tank 11 shakes or the water surface in the clean water tank 11 fluctuates, it will not penetrate or spill out from the gap in the top cover of the clean water tank 11, thereby ensuring the cleanliness of the area near the clean water tank 11.

[0047] In the second aspect, the utility model provides a cleaning robot 2 adapted to the above passive base station 1, which can be specifically referred to Figure 5 One of the embodiments shown in Figure 6 In another embodiment shown in the figure, the cleaning robot 2 includes a clean water box 21 for storing clean water, and a water injection drive 22. The clean water in the clean water box 21 can be used for the cleaning robot 2 to complete floor cleaning and self-cleaning tasks. The clean water docking assembly 12 is docked with the clean water box 21. The clean water docking assembly 12 includes a normally closed mechanism for closing the water outlet 112 under normal conditions. The water injection drive 22 is connected to the normally closed mechanism and is used to drive the normally closed mechanism to open the water outlet 112 so that the clean water in the clean water tank 11 flows into the clean water box 21.

[0048] In some embodiments, the water injection drive 22 provided on the cleaning robot 2 is used to drive the normally closed mechanism to switch from a closed state to an open state after the clean water box 21 of the cleaning robot 2 is docked with the clean water docking assembly 12 of the clean water base station, thereby opening the water outlet 112 of the clean water base station and allowing clean water to flow into the clean water box 21; through the setting of the water injection drive 22, a driving force for opening the water outlet 112 of the clean water base station can be provided, that is, the clean water base station does not need to provide additional driving force for the opening and closing of the water outlet 112. At this time, the water outlet 112 of the clean water base station can be opened by setting valves, baffles, etc. without external The normally closed mechanism is in a normally closed state under force drive, and is used to cooperate with the water injection drive component 22. It should be understood that the normally closed mechanism can always provide a compressive elastic force to the valve or baffle structure through a spring or other structure, so as to ensure the sealing of the water outlet 112. The normally closed mechanism can also be opened by setting a trigger pressure. When the amount of clean water in the clean water tank 11 reaches the preset requirement, the pressure reaching the trigger pressure value cannot be applied to the normally closed mechanism. At this time, the water injection drive component 22, such as a mechanical lever or an air pump or other structure, is used to increase the pressure in the opening direction of the normally closed mechanism, and the normally closed mechanism will open and open the water outlet 112.

[0049] Continue to refer to Figure 5 and Figure 6 As shown, the water injection drive component 22 is an air pump or a telescopic mechanism; when the water injection drive component 22 is an air pump, the water injection drive component 22 is connected to the clean water box 21, and after the clean water box 21 is connected to the water outlet 112, the air pump is used to extract the air in the clean water box 21 to form a negative pressure, thereby switching the normally closed mechanism to an open state and opening the water outlet 112; when the water injection drive component 22 is a telescopic mechanism driven by a motor, after the clean water box 21 is connected to the water outlet 112, the normally closed mechanism is pushed to switch the normally closed mechanism to an open state and open the water outlet 112; the water injection drive component 22 can also be a mechanical lever or other device that can provide a driving force for opening the normally closed mechanism.

[0050] Specifically, after the cleaning robot 2 moves to the clean water base station and after the water outlet 112 of the clean water base station is docked with the clean water box 21, the clean water in the clean water base station can be directly injected into the clean water box 21, so that the cleaning robot 2 can perform ground cleaning or self-cleaning and other tasks; specifically, a water level monitoring component can be provided in the clean water box 21, which is used to monitor whether the amount of clean water in the clean water box 21 meets the requirements. When the amount of clean water in the clean water box 21 meets the requirements, the water outlet 112 of the clean water base station is closed, the cleaning robot 2 drives away from the clean water base station, and performs ground cleaning or self-cleaning and other tasks.

[0051] In some embodiments, the cleaning robot 2 includes at least one of a drying module, a charging module, and a dust collection module, which respectively correspond to a drying base station, a charging base station, and a dust collection base station separated from the passive base station 1; that is, the passive base station 1 can only realize the function of replenishing clean water for the cleaning robot 2, and can be set at a location where no external power supply is required, as long as the location can be connected to an external water source; specifically, it can be a kitchen, bathroom, balcony and other locations in a home environment; thereby realizing the functional division of multiple base stations and providing a more reasonable working route and working environment for the cleaning robot 2.

[0052] In a further embodiment, the cleaning robot 2 also includes a self-cleaning module, which is used to perform self-cleaning when the cleaning robot 2 is located at a station to be cleaned, or when the cleaning robot 2 is docked with the clean water docking assembly 12; it should be understood that the cleaning robot 2 can automatically clean the mop and other cleaning tools at the bottom when using the self-cleaning module, and the station to be cleaned can specifically be near the passive base station 1 or other base stations to avoid contaminating the floor in the house and affecting the normal life of the user.

[0053] The specific implementation method and implementation principle are the same as those in the above embodiment, and can bring the same or similar technical effects, which will not be described one by one here. For details, please refer to the description of the above passive base station embodiment for a cleaning robot.
