Description

Technical Field

[0001] This invention relates to the field of smart toilets, specifically to a smart toilet with a robotic arm and a control method thereof. Background Technology

[0002] A toilet currently has a rotating nozzle installed below the central area of ​​the lid, which is integrated with the bottom edge of the lid via a connecting rod. Although this rotating nozzle can be used to rinse the toilet bowl and seat, its location inside the lid makes it highly susceptible to contamination from bacteria and wastewater splashing onto its surface during flushing. This contamination is particularly severe when flushing with the lid closed, directly impacting the hygienic effect of subsequent rinses. Furthermore, placing the rotating nozzle inside the lid increases its overall weight, making manual opening inconvenient for users and affecting the smooth operation of the automatic lid-opening function. Summary of the Invention

[0003] The first objective of this invention is to provide a safe, hygienic, and automatically cleaning smart toilet with a robotic arm.

[0004] A second objective of this invention is to provide a control method for the aforementioned intelligent toilet with a robotic arm.

[0005] To achieve the aforementioned first objective, the present invention provides an intelligent toilet with a robotic arm, comprising a toilet body, a seat ring, and a robotic arm. The seat ring is rotatably connected above the toilet body. The first end of the robotic arm is connected to the toilet body, and the second end of the robotic arm is movable in the horizontal and vertical directions to extend above the seat ring or the toilet body. The second end of the robotic arm is provided with a cleaning head.

[0006] As can be seen from the above solution, by installing a robotic arm on the toilet body, the robotic arm can automatically extend when cleaning is needed. When the seat is in the lowered position, the robotic arm cleans the surface of the seat; when the seat is flipped up, the robotic arm cleans the toilet skirt at the top of the toilet body, which helps to meet the cleaning needs of both male and female users. Compared with the prior art, this invention performs cleaning with the lid open, which not only achieves automatic cleaning but also effectively reduces the overall weight of the lid.

[0007] A further design involves providing a receiving cavity on one side of the toilet body, recessed into the outer wall of the toilet body, and positioned below the seat ring; the first end of a robotic arm is rotatably connected to the receiving cavity, and the second end of the robotic arm can extend or retract into the receiving cavity.

[0008] As can be seen from the above solution, after cleaning, the robotic arm will retract and embed itself inside the toilet body, keeping the cleaning head away from the internal space of the toilet. This effectively avoids contamination caused by bacteria and sewage during flushing, while also saving space and ensuring that the user's normal use is not affected in any way.

[0009] A further embodiment is that the robotic arm includes a first rotating arm, a first rotary drive, a second rotating arm, a second rotary drive, an operating arm, and an operating rotary drive; the first end of the first rotating arm is rotatably connected to one end of the receiving cavity, and the first rotary drive drives the first rotating arm to rotate about a first axis; the second end of the first rotating arm is rotatably connected to the first end of the second rotating arm, and the second rotary drive drives the second rotating arm to rotate about a second axis, the second axis being perpendicular to the first axis; the operating arm is connected to the second end of the second rotating arm, and the operating rotary drive drives the operating arm to rotate about an operating axis.

[0010] As can be seen from the above solution, the operating arm can be flexibly extended above the seat or toilet skirt through the above settings, thereby enabling convenient and efficient cleaning of the corresponding area.

[0011] A further embodiment is that the robotic arm also includes a third rotating arm and a third rotary drive. The two ends of the third rotating arm are rotatably connected to the second end of the second rotating arm and the first end of the operating arm, respectively. The third rotary drive drives the third rotating arm to rotate around a third axis, which is parallel to the second axis and perpendicular to the operating axis.

[0012] As can be seen from the above scheme, the above settings help to increase the cleaning range of the operating arm, enabling it to completely cover the entire seat and toilet skirt, thereby completely eliminating cleaning dead corners.

[0013] A further solution is to have a cleaning head equipped with a nozzle and / or a sterilization module, wherein the nozzle can spray water and / or blow air, and the sterilization module can emit sterilization light. As can be seen from the above solution, the above setup ensures that the cleaning process follows a sequence of rinsing with water first, followed by air drying, which guarantees hygiene and facilitates subsequent use. It also facilitates thorough sterilization and disinfection of the toilet seat or toilet skirt, comprehensively improving safety during use.

[0014] A further solution is that the smart toilet with a robotic arm also includes an air pump and / or a water pump. The air pump is equipped with an air inlet for connecting to the outside world, and the air outlet of the air pump is connected to the nozzle through an air outlet pipe. The water pump is equipped with a water inlet pipe for connecting to a water source, and the water pump is connected to the nozzle through a water outlet pipe.

[0015] A further design involves a mounting base at the rear of the toilet body, on which a control module, an air pump, and a water pump are mounted. The control module is electrically connected to the air pump and the water pump, respectively. A common pipe is connected to the robotic arm, with one end of the water outlet pipe and one end of the air outlet pipe connected to the first end of the common pipe, and the second end of the common pipe connected to the nozzle.

[0016] As can be seen from the above scheme, the above settings help to reduce the number of pipes and facilitate pipe laying.

[0017] A further solution is that the smart toilet with a robotic arm also includes a flip-up lid, which is positioned above the seat ring and has a human body detection module that is electrically connected to the control module.

[0018] As can be seen from the above solution, by setting up a human detection module, the user's status can be monitored in real time, and automatic cleaning can be triggered immediately after the user moves away.

[0019] A further solution is to install a wireless charging module in the seat ring, with the wireless charging module corresponding to the human body detection module.

[0020] As can be seen from the above solution, by setting up a wireless charging module, a convenient charging method is provided for the human body detection module.

[0021] To achieve the second objective mentioned above, the present invention provides a control method for an intelligent toilet with a robotic arm, comprising the following steps: The human detection module detects whether the user has left. If so, the robotic arm is extended to move the cleaning head above the area to be cleaned; Start the cleaning program, first control the nozzle to spray water to rinse the area to be cleaned, then control the nozzle to blow air to dry the area to be cleaned, and then control the sterilization module to disinfect and sterilize the area to be cleaned. During the cleaning process, the human detection module detects whether a user is approaching in real time. If so, the cleaning process is stopped immediately and the robotic arm is controlled to retract to its initial position. Attached Figure Description

The second end of the common pipe 10 extends along the extension direction of the robotic arm 4 and is connected to the nozzle 49. The water pump 9 and the air pump 8 are started alternately by the control module 7 to achieve water spraying followed by air blowing.

[0041] To prevent flushing water from entering the air pump 8, a one-way valve 82 can be installed on the air outlet pipe 81 to ensure that gas can move from one end of the air pump 8 to the other end of the common pipe 10, and that flushing water cannot enter the air pump 8 from the other end of the common pipe 10 through the air outlet pipe 81.

The nozzle of the nozzle 49 is arranged facing the second end of the operating arm 47, and the nozzle 49 can spray water and / or blow air. During water spraying or air blowing, the nozzle 49 can spray water or blow air from the center of the area to be cleaned outwards, or from the outside of the area to be cleaned towards the center, without limitation. The sterilization module 50 is located on one side of the nozzle 49, and the sterilization module 50 is used to irradiate sterilization light outwards, facilitating the disinfection of the entire toilet. The sterilization module 50 is preferably an ultraviolet lamp. To facilitate the laying of the common pipe 10, a first groove 411 is provided on the first rotating arm 41. The first groove 411 extends along the length of the first rotating arm 41, and a first through hole 412 and a second through hole 413 are respectively opened at both ends of the first rotating arm 41.

[0056] The wiring routing of the sterilization module 50 is set with reference to the routing of the common conduit 10, and will not be described again here.

[0057] See Figure 7 The first rotary drive component 42 includes a motor 421, a drive gear 422, a driven gear 423, a planetary carrier 424, and an upper cover 425.

[0058] The driving gear 422 is mounted on the drive shaft of the motor 421. There are three driven gears 423, which are respectively mounted on the outer periphery of the driving gear 422. The planetary carrier 424 is mounted above the driven gears 423. The upper and lower sides of the planetary carrier 424 are respectively provided with a first power rod 4241 and three fixed shafts 4242, and the driven gears 423 are mounted on the corresponding fixed shafts 4242.

[0060] When the motor 421 starts, the driving gear 422 drives the driven gear 423 to rotate. With the cooperation of the teeth, the driven gear 423 also revolves around the sun, thereby driving the planetary carrier 424 and the first power rod 4241 to rotate.

[0061] The structures of the second rotary drive member 44, the third rotary drive member 46, and the operating rotary drive member 48 are all the same as those of the first rotary drive member 42, and will not be described again here.

[0062] In another embodiment, the first rotary drive 42, the second rotary drive 44, the third rotary drive 46 and the operating rotary drive 48 can also be servos. The structure of the servos is prior art and will not be described in detail here.

[0063] Combination Figure 1 and Figure 2 A human body detection module 31 is provided on the inward side of the upper cover 3, and the human body detection module 31 is electrically connected to the control module 7. The human body detection module 31 can be a distance sensor, preferably an infrared distance sensor.

[0064] When the top cover 3 is open, the human body detection module 31 emits a detection light directly above the seat ring 2 to detect whether the user has left. Once the user is detected to have left, the control module 7 controls the robotic arm 4 to extend and perform cleaning operations.

[0065] In this embodiment, a capacitor or battery is provided inside the human body detection module 31. A wireless charging module (not shown in the figure) is provided on the inner front side of the seat ring 2, and the wireless charging module is correspondingly provided with the human body detection module 31.

[0066] In the vertical direction, the rotation axis of the seat ring 2 is lower than the rotation axis of the upper cover 3; in the horizontal direction, the rotation axis of the seat ring 2 is located in front of the rotation axis of the upper cover 3.

[0067] When the top cover 3 is flipped down onto the seat ring 2, the capacitor or battery of the human body detection module 31 is just close to the wireless charging module, making it convenient to wirelessly charge it.

[0068] When both the top cover 3 and the seat ring 2 are flipped upwards, the highest point of the seat ring 2 is lower than the location of the human body detection module 31, thus preventing the seat ring 2 from obstructing the human body detection module 31.

[0069] Example of a control method for a smart toilet with a robotic arm: Combination Figures 1 to 7 Based on the above-described smart toilet embodiment, the control method provided in this embodiment includes the following steps: The human body detection module 31 detects whether the user has left; If so, the control module 7 controls the robotic arm 4 to extend, so that the cleaning head moves above the area to be cleaned. When the seat ring 2 is in the flipped-down state, the area to be cleaned refers to the surface of the seat ring 2; when the seat ring 2 is in the flipped-up state, the area to be cleaned is the toilet skirt 11.

[0070] The cleaning process begins with the control module 7 initiating a series of actions. First, the control module 7 controls the nozzles 49 to spray water, rinsing the area to be cleaned from the inside out or from the outside in. Then, the control module 7 controls the nozzles 49 to blow air from the inside out or from the outside in to dry any remaining moisture in the area. Next, the control module 50 activates, using ultraviolet light to disinfect the area. During the water spraying, air blowing, and disinfection processes, the robotic arm 4 moves above the area to be cleaned along a preset trajectory, ensuring that the entire area is rinsed, dried, and disinfected. The preset trajectory extends from the starting point of the area to its endpoint, with the starting and ending points coinciding.

[0071] During the cleaning process, the human body detection module 31 detects in real time whether the user is close. If so, the control module 7 immediately stops the cleaning program, that is, turns off the water pump 9, air pump 8 and sterilization module 50, and controls the robotic arm 4 to retract to the initial position. In this embodiment, the initial position is inside the receiving cavity 121 of the toilet body 1.

[0072] In summary, this invention, by incorporating a robotic arm 4 on the toilet body 1, automatically extends when cleaning is required. When the seat ring 2 is in the lowered position, the robotic arm 4 cleans the surface of the seat ring 2; when the seat ring 2 is flipped up, the robotic arm 4 cleans the toilet skirt 11 at the top of the toilet body 1, thus simultaneously meeting the cleaning needs of both male and female users. Compared with existing technologies, this invention performs cleaning while the lid 3 is open, not only achieving automatic cleaning but also effectively reducing the overall weight of the lid 3.

[0073] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
