Description

Technical Field

[0001] This application relates to the field of robotic vacuum cleaner base station technology, and in particular to a self-cleaning robotic vacuum cleaner base station. Background Technology

[0002] The robot vacuum cleaner base station is the core supporting hub of the robot vacuum cleaner's intelligent cleaning system and the core carrier for realizing fully automated and unmanned sweeping and mopping operations. Its most basic core function is to provide the robot vacuum cleaner's main unit with accurate recharging positioning and power replenishment. The mainstream all-in-one base station now integrates multiple functions such as automatic dust collection, automatic mop cleaning and hot air drying, automatic water tank replenishment for the main unit, antibacterial and sterilization of the cleaning water circuit, and even automatic water supply and drainage. It integrates the post-cleaning processing steps that originally required frequent manual intervention into the entire process, reducing manual operation at the source and enabling the robot vacuum cleaner to truly achieve a closed-loop automated operation of "sweeping, mopping, washing, drying, and dust collection".

[0003] In daily home use, the core purpose of the robot vacuum's base station is to comprehensively reduce the frequency of manual cleaning, completely freeing up your hands for home cleaning. During daily cleaning, it can automatically recharge when the robot vacuum's main unit's battery is low, ensuring continuous cleaning of the entire house in large homes without the need for manual supervision or plugging and unplugging. After cleaning, it can automatically suck dust, hair, debris, and other garbage from the main unit's dustbin into the base station's large-capacity sealed dust bag, avoiding frequent manual cleaning of the dustbin. Most models only need to replace the dust bag every few months. For mopping scenarios, the base station can automatically wash, rub, and dry the mop with hot air, completely eliminating the hassle of hand-washing dirty mops.

[0004] However, existing base stations with mop cleaning functions generally have the following drawbacks: when the base station cleans the robot's cleaning end, the cleaning mechanism in the base station will wash off the mud and dust on the mop. These washed-off dirt and grime fall directly into the base station under gravity. If they are not treated, they will accumulate over time and form stubborn stains that are easy to stick back to the robot vacuum cleaner, causing secondary pollution to the surrounding environment and making it difficult for people to use. Summary of the Invention

[0005] The purpose of this application is to address the problem in the background technology that dirt washed away falls directly into the base station under gravity, and if not treated, it will accumulate over a long period of time to form stubborn stains that easily stick back to the robot vacuum cleaner, causing secondary pollution to the surrounding environment and making it unsuitable for people to use. This application provides a self-cleaning robot vacuum cleaner base station.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A self-cleaning robotic vacuum cleaner base station includes a base station body. A cleaning chamber is located at the bottom of the base station body, and a guide ramp is fixedly connected to one side of the bottom of the base station body. A touchscreen controller is installed on the base station body. A brush disc is installed on one side of the inner bottom of the cleaning chamber, and a water guiding structure is provided at the inner bottom of the cleaning chamber. A water tank is fixedly connected to one side of the base station body. Sprayers are installed on both sides of the water tank, with the spray ends of the sprayers installed on the inner wall of the cleaning chamber. A drive unit is fixedly connected to one side of the water tank, and the drive unit communicates with the sprayers on one side. A cleaning brush is installed inside the cleaning chamber, and the cleaning brush is driven by the drive unit. A waterproof component is installed on the guide ramp.

[0007] By adopting the above technical solution, when the robot vacuum enters the cleaning chamber, the brush disc can clean the cleaning components of the robot vacuum. After the robot vacuum is cleaned, it can be removed from the cleaning chamber. At this time, the touch screen controller can activate the spraying device. The operation of the spraying device causes its internal components to draw water from the water tank and spray the water into the cleaning chamber through the spraying end of the spraying device. This allows the cleaning chamber to self-clean, cleaning up the dirt dropped by the robot vacuum during cleaning, preventing dirt, odors, and bacterial growth on the bottom plate, avoiding the base station from becoming a secondary source of pollution, and maximizing the cleanliness and hygiene of the base station interior and the subsequent cleaning quality of the robot vacuum.

[0008] Furthermore, the water guiding structure includes a liquid guiding cavity formed at the bottom of the cleaning chamber, and multiple sets of leakage holes are formed at the bottom of the cleaning chamber, the leakage holes being in communication with the liquid guiding cavity.

[0009] By adopting the above technical solution, the wastewater generated during cleaning can flow into the liquid guiding cavity through the leakage hole, and then be guided to the water tank through the liquid guiding cavity so that the water tank can collect the wastewater.

[0010] Furthermore, a partition plate is fixedly connected to the middle of the interior of the water tank, which divides the water tank into a clean water tank and a wastewater tank. A filter screen is installed at the bottom of the wastewater tank. A sludge pump is fixedly connected to the bottom of the water tank. A sludge suction head is fixedly connected to the output end of the sludge pump. The sludge suction head is connected to the liquid guiding chamber. The drain end of the sludge pump is connected to the wastewater tank.

[0011] By adopting the above technical solution, a water inlet is provided on the top of the water tank, which can be used to replenish clean water to the clean water tank, while a drain outlet is provided on one side of the water tank, which can be used to discharge debris and water from the sewage tank.

[0012] Furthermore, the spraying component includes a pump fixedly connected to one side of the water tank. The two pumping ends of the pump correspond to the clean water tank and the wastewater tank, respectively. The output end of the pump is fixedly connected to a delivery pipe. One end of the delivery pipe is fixedly connected to a branch pipe. The branch pipe is installed on the base station body and multiple nozzles are fixedly connected to the branch pipe.

[0013] By adopting the above technical solution, the water inside the clean water tank or sewage tank can be extracted by the operation of the pump and transported to the delivery pipe. The water is then transported to the distribution pipe and sprayed into the clean tank through multiple nozzles.

[0014] Furthermore, the driving component includes a water passage box fixedly connected to one side of the water tank, a rotating shaft rotatably connected inside the water passage box, a driving impeller mounted on the rotating shaft, and the delivery pipe communicating with the water passage box.

[0015] By adopting the above technical solution, when the spraying component on one side is running, water can enter the water box from the delivery pipe, causing the drive impeller to rotate under the impact of the water flow, which in turn drives the rotating shaft to rotate, thereby driving the cleaning component.

[0016] Furthermore, the cleaning chamber has sliding grooves on both sides. The cleaning brush includes a drive plate that is slidably installed inside the sliding groove. A cleaning brush is fixedly connected to the bottom of the drive plate. A bidirectional threaded rod is threaded to one end of the drive plate, and a guide rod is threaded through the other side of the drive plate. The bidirectional threaded rod and the guide rod are respectively installed inside the two sliding grooves. A linkage is provided at one end of the bidirectional threaded rod, and the linkage is connected to the drive component in a transmission manner.

[0017] By adopting the above technical solution, the driving component can drive the linkage component, which can drive the bidirectional threaded rod to rotate. The rotating bidirectional threaded rod can drive the driving plate, causing the driving plate to reciprocate inside the slide groove, which can drive the cleaning brush to reciprocate to clean the bottom of the cleaning chamber.

[0018] Furthermore, the linkage includes a connecting box fixedly connected to one side of the base station body, an active disk rotatably connected to one end of the connecting box, a driven wheel fixedly connected to one end of the bidirectional threaded rod, a transmission belt drivingly connecting the active disk and the driven wheel, and one side of the active disk fixedly connected to the rotating shaft.

[0019] By adopting the above technical solution, the rotating shaft can drive the active disk to rotate, and the active disk will drive the driven wheel to rotate through the transmission belt, which in turn will drive the bidirectional threaded rod to rotate. The rotating bidirectional threaded rod can then drive the drive plate.

[0020] Furthermore, the waterproof component includes a servo motor fixedly connected to one side of the guide slope, an inner groove is provided on the guide slope, a water-proof plate is slidably connected inside the inner groove, a threaded drive rod is fixedly connected to the output end of the servo motor, the threaded drive rod is threadedly connected to the water-proof plate, and the threaded drive rod is through-connected to the guide slope.

[0021] By adopting the above technical solution, the servo motor can drive the threaded drive rod to rotate, and the rotating threaded drive rod can drive the baffle plate, causing the baffle plate to rise from the inner tank, thereby sealing the bottom of the opening of the cleaning chamber.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, when the robot vacuum enters the cleaning chamber, the cleaning components of the robot vacuum can be cleaned by the brush disc. After the robot vacuum is cleaned, it can be removed from the cleaning chamber. At this time, the touch screen controller can activate the spraying device. The operation of the spraying device causes its internal components to draw water from the water tank and spray the water into the cleaning chamber through the spraying end of the spraying device. This can perform self-cleaning of the cleaning chamber, clean up the dirt dropped by the robot vacuum during cleaning, prevent dirt, odor and bacteria growth on the bottom plate, avoid the base station becoming a secondary pollution source, and maximize the cleanliness and hygiene of the base station and the subsequent cleaning quality of the robot vacuum.

[0023] 2. In this application, the water tank is equipped with a clean water tank and a wastewater tank. When wastewater is generated during cleaning in the cleaning tank, it can be guided to the water tank through a water guiding structure. The wastewater is then pumped into the wastewater tank by internal components of the water tank for separation of water and impurities. When the spraying component cleans the inside of the cleaning tank, water can be drawn from the clean water tank or the water after impurity separation can be drawn from the wastewater tank. This allows for alternating extraction and use of water from the clean water tank and the wastewater tank during cleaning, thereby improving the utilization rate of water during cleaning and saving water resources.

[0024] 3. In this application, when the spraying component on one side draws water, the force generated by the water can drive the driving component, causing the internal components of the driving component to operate, which in turn drives the cleaning component, causing the internal components of the cleaning component to operate. Through its internal components, the bottom of the cleaning chamber can be cleaned, further removing dust and impurities adhering to the inside of the cleaning chamber. At the same time, the cleaning component can work with the water sprayed by the spraying component to perform a deep cleaning of the cleaning chamber, maximizing cleaning efficiency and cleaning quality.

[0025] 4. In this application, when the sweeping robot enters the cleaning chamber, the operation of the waterproof component allows the internal components of the waterproof component to rise within the guide slope, thereby sealing the lower end of the cleaning chamber. This prevents wastewater from overflowing when the base station cleans the sweeping robot, avoiding pollution to the surrounding environment and improving the cleanliness of the cleaning. At the same time, when the spray component performs self-cleaning on the inside of the cleaning chamber, the internal components of the waterproof component can rise again to block the wastewater generated during self-cleaning and prevent wastewater from overflowing.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0029] This application discloses a self-cleaning robot base station.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6A self-cleaning sweeping robot base station includes a base station body 1, a cleaning chamber at the bottom of the base station body 1, and a guide slope 3 fixedly connected to one side of the bottom of the base station body 1. A touch screen controller 2 is installed on the base station body 1. A brush disc 9 is installed on one side of the inner bottom of the cleaning chamber, and a water guiding structure is provided at the inner bottom of the cleaning chamber. A water tank 4 is fixedly connected to one side of the base station body 1. Spraying components 5 are installed on both sides of the water tank 4. The spraying end of the spraying component 5 is installed on the inner wall of the cleaning chamber. A driving component 6 is fixedly connected to one side of the water tank 4. The driving component 6 is connected to the spraying component 5 on one side. A cleaning brush 7 is installed inside the cleaning chamber. The cleaning brush 7 is connected to the driving component 6. A waterproof component 8 is installed on the guide slope 3. The water guiding structure includes a liquid guiding cavity 12 located at the bottom of the cleaning chamber. Multiple sets of leakage holes 11 are provided at the bottom of the cleaning chamber. The leakage holes 11 are connected to the liquid guiding cavity 12. Here, the wastewater generated during cleaning can flow into the liquid guiding cavity 12 through the leakage holes 11 and be guided to the water tank 4 through the liquid guiding cavity 12 so that the water tank 4 can collect the wastewater.

[0031] The sweeping robot drives into the cleaning chamber at the bottom of the base station body 1 via the guide ramp 3. After it arrives in place, the touch screen controller 2 issues a control command to activate the waterproof component 8 installed on the guide ramp 3. The waterproof component 8 rises from inside the guide ramp 3 to seal and block the bottom of the cleaning chamber opening, completing the pre-cleaning protection and preventing the sewage generated by subsequent cleaning operations from overflowing and polluting the surrounding environment. After the pre-protection is completed, the brush disk 9 on one side of the bottom of the cleaning chamber starts to operate, rotating and brushing the cleaning parts of the sweeping robot to remove dust, hair, stains and other dirt attached to the cleaning parts; the wastewater generated during the brushing process flows into the liquid guiding chamber 12 below through multiple sets of leakage holes 11 opened at the bottom of the cleaning chamber, and is guided to the water tank 4 on one side of the base station body 1 through the water guiding structure formed by the leakage holes 11 and the liquid guiding chamber 12, and is finally pumped into the wastewater tank of the water tank 4 for solid-liquid separation treatment, thus completing the cleaning operation of the sweeping robot; After the robot vacuum cleaner finishes cleaning and leaves the cleaning chamber, the touch screen controller 2 activates the drive unit 6 on one side of the water tank 4 and the spray units 5 on both sides of the water tank 4. The spray units 5 draw cleaning water from the water tank 4 and spray it into the cleaning chamber through the spray nozzles installed on the inner wall of the cleaning chamber, rinsing the inner wall and bottom of the cleaning chamber and removing residual dirt. At the same time, the fluid force generated by the spray unit 5 in delivering water drives the drive unit 6 connected to it to rotate. The drive unit 6 synchronously drives the cleaning brush unit 7 inside the cleaning chamber, causing the cleaning brush unit 7 to rotate and mechanically clean the bottom of the cleaning chamber. Together with the spray water, it achieves deep self-cleaning of the cleaning chamber, preventing dirt accumulation, bacterial growth and odor generation inside the chamber. The water tank 4 is divided into an independent clean water tank and a wastewater tank. During the cleaning operation, the clean water tank provides the original clean water source for the spraying component 5. The wastewater generated by the cleaning robot and the base station self-cleaning is guided by the water guiding structure composed of the leakage hole 11 and the liquid guiding cavity 12 and then pumped into the wastewater tank to complete solid-liquid separation. During the self-cleaning operation, the spraying component 5 can alternately draw clean water from the clean water tank and the recycled water after solid-liquid separation from the wastewater tank for rinsing the tank body, which greatly improves the water utilization rate and reduces water consumption. This base station activates waterproof protection in both core cleaning phases, forming a closed-loop anti-overflow system: First, during the robot vacuum's entry and cleaning phase, the waterproof component 8 rises to seal the bottom of the cleaning chamber opening, preventing wastewater generated by the brush disc 9 from overflowing; second, during the base station's self-cleaning phase, the waterproof component 8 rises again to seal the chamber opening, preventing rinsing wastewater generated by the spray component 5 and the brush component 7 from overflowing; after the entire cleaning process is completed, the touch screen controller 2 controls the waterproof component 8 to retract into the guide ramp 3, restoring the guide ramp 3's passage function and ensuring the robot vacuum's normal entry and exit from the chamber subsequently.

[0032] Reference Figure 4 A partition plate 41 is fixedly connected to the middle of the interior of the water tank 4. The partition plate 41 divides the water tank 4 into a clean water tank and a sewage tank. A filter screen plate 42 is installed at the bottom of the sewage tank. A sewage pump 43 is fixedly connected to the bottom of the water tank 4. A sewage head 44 is fixedly connected to the output end of the sewage pump 43. The sewage head 44 is connected to the liquid guiding chamber 12. The drain end of the sewage pump 43 is connected to the sewage tank.

[0033] The top of the water tank 4 is equipped with a water inlet, which can be used to replenish clean water to the clean water tank. The side of the water tank 4 is equipped with a drain outlet, which can be used to discharge debris and water from the sewage tank. By operating the sewage pump 43, the sewage in the liquid guiding chamber 12 can be extracted by the sewage suction head 44 and transported to the sewage tank. During this process, the impurities in the sewage are filtered by the filter screen 42, thereby separating the impurities and water in the sewage.

[0034] Reference Figure 4 and Figure 5 The spraying component 5 includes a pump 51 fixedly connected to one side of the water tank 4. The two pumping ends of the pump 51 correspond to the clean water tank and the sewage tank, respectively. The output end of the pump 51 is fixedly connected to a delivery pipe 52. One end of the delivery pipe 52 is fixedly connected to a diversion pipe 53. The diversion pipe 53 is installed on the base station body 1, and multiple nozzles 54 are fixedly connected to the diversion pipe 53.

[0035] By operating the pump 51, water can be extracted from the clean water tank or the wastewater tank and transported to the delivery pipe 52. The water is then transported to the distribution pipe 53, and the water is sprayed into the cleaning tank through multiple nozzles 54 to rinse the inside of the cleaning tank.

[0036] Reference Figure 5 and Figure 6 The driving component 6 includes a water box 61 fixedly connected to one side of the water tank 4. A rotating shaft 62 is rotatably connected inside the water box 61, and a driving impeller 63 is mounted on the rotating shaft 62. The delivery pipe 52 communicates with the water box 61. Slide grooves are provided on both sides of the cleaning chamber. The cleaning brush component 7 includes a driving plate 77 slidably installed inside the slide grooves. A cleaning brush 78 is fixedly connected to the bottom of the driving plate 77. A bidirectional threaded rod 75 is threaded to one end of the driving plate 77, and a guide rod is threaded through the other side of the driving plate 77. Rod 76, bidirectional threaded rod 75 and guide rod 76 are respectively installed inside two slide grooves. One end of bidirectional threaded rod 75 is provided with a linkage component, which is connected to drive component 6. The linkage component includes a connecting box 71 fixedly connected to one side of base station body 1. One end of the connecting box 71 is rotatably connected to an active disk 72. One end of bidirectional threaded rod 75 is fixedly connected to a driven wheel 74. A transmission belt 73 is connected between the active disk 72 and the driven wheel 74. One side of the active disk 72 is fixedly connected to the rotating shaft 62.

[0037] When the spray element 5 on one side is running, water can enter the water box 61 from the delivery pipe 52, causing the drive impeller 63 to rotate under the impact of the water flow, which in turn drives the rotating shaft 62 to rotate. The rotating shaft 62 drives the drive disc 72 to rotate, and through the transmission belt 73 drives the driven wheel 74 to rotate, which in turn drives the bidirectional threaded rod 75 to rotate. The rotating bidirectional threaded rod 75 drives the drive plate 77 to move back and forth inside the slide groove, which drives the cleaning brush 78 to reciprocate to clean the bottom of the cleaning chamber. This, together with the water sprayed by the spray element 5, performs deep cleaning. Here, when the drive plate 77 moves, the guide rod 76 can further limit and guide the drive plate 77 to prevent the drive plate 77 from warping when moving, and at the same time improve the smoothness of the movement of the drive plate 77.

[0038] Reference Figure 7 The waterproof component 8 includes a servo motor 82 fixedly connected to one side of the guide slope 3. The guide slope 3 has an inner groove 81, and a water-proof plate 84 is slidably connected inside the inner groove 81. The output end of the servo motor 82 is fixedly connected to a threaded drive rod 83, which is threadedly connected to the water-proof plate 84 and is through-connected to the guide slope 3.

[0039] When the servo motor 82 is running, it can drive the threaded drive rod 83 to rotate. The rotating threaded drive rod 83 can drive the baffle plate 84, so that the baffle plate 84 rises from the inner tank 81, which can seal the bottom of the opening of the cleaning chamber to prevent the sewage inside the cleaning chamber from flowing out and polluting the surrounding environment.

[0040] Working principle: After the sweeping robot enters the cleaning chamber at the bottom of the base station body 1 via the guide ramp 3, the touch screen controller 2 controls the waterproof component 8 on the guide ramp 3 to rise and seal the bottom of the cleaning chamber opening, forming an overflow protection to prevent the sewage generated during cleaning from overflowing and polluting the surrounding environment. After the protection is in place, the brush disk 9 at the bottom of the cleaning chamber starts to operate, rotating and brushing the cleaning parts of the sweeping robot to remove the attached dirt; the wastewater generated by brushing flows into the liquid guiding chamber 12 through multiple sets of leakage holes 11 at the bottom of the cleaning chamber, and is guided to the water tank 4 through the water guiding structure, and finally pumped into its wastewater tank to complete solid-liquid separation. After the robot vacuum cleaner finishes cleaning and leaves the chamber, the touch screen controller 2 activates the spray component 5 and the drive component 6. The spray component 5 draws cleaning water from the water tank 4 and sprays it through the water spray end on the inner wall of the cleaning chamber to rinse the chamber body under high pressure. At the same time, the fluid force generated by the water spray component 5 drives the drive component 6 to operate, synchronously driving the cleaning brush component 7 in the cleaning chamber to mechanically clean the bottom of the chamber. Combined with the spraying, the chamber body is deeply self-cleaned, preventing the accumulation of dirt, the growth of bacteria and the generation of odors. The water tank 4 is divided into a clean water tank and a wastewater tank. The clean water tank provides the original water source for cleaning operations. The wastewater generated during cleaning is recycled to the wastewater tank through the water guiding structure to complete solid-liquid separation. During the self-cleaning process, the spraying component 5 can alternately draw clean water from the clean water tank and the recycled water from the wastewater tank to rinse the tank body, which greatly improves the water utilization rate and reduces water consumption. This base station forms a two-stage waterproof and overflow prevention closed loop: during the cleaning stage when the sweeping robot enters the compartment, the waterproof component 8 rises to prevent the cleaning wastewater from overflowing; during the base station's self-cleaning stage, the waterproof component 8 rises again to seal the compartment opening and prevent the rinsing wastewater from overflowing; after the entire process is completed, the waterproof component 8 retracts into the guide slope 3 to restore the passage function and ensure that the sweeping robot can enter and exit the compartment normally in the future.
