Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a contactless cleaning robotic arm. Background Technology

[0002] Toilets, as a common sanitary fixture, are difficult to clean in real time, especially in public places. Because they cannot be cleaned immediately after each use, they are easily contaminated by urine, sweat, and other waste. This waste mainly accumulates on the surface of the toilet seat that contacts the buttocks and on the skirt of the toilet seat that supports the pelvic cavity. Because they cannot be cleaned immediately, the waste accumulates quickly, emitting unpleasant odors and leaving obvious stains. Moreover, the accumulated dirt becomes even more difficult to remove, leading to a negative user experience. Even in some public places (such as airports and hotels) where manual cleaning is relatively timely, contact cleaning tools are generally used, and these tools themselves are not necessarily very clean and may be another source of bacterial and viral contamination.

[0003] An automatic toilet cleaning device is currently available, installed inside the toilet seat, comprising a large arm and a small arm, with a cleaning brush mounted on the small arm. When not in use, the large and small arms retract and fold inside the toilet seat. After flushing, the large and small arms extend downwards, allowing the cleaning brush to move down and clean the inner wall and bottom of the toilet. However, placing the cleaning brush on the toilet seat is neither hygienic nor aesthetically pleasing. Furthermore, because this cleaning device only has a large and small arm, the working range of the cleaning brush is limited. If it were placed in other locations, such as on the outside of the toilet body, its limited range of motion and angle would prevent it from completing the cleaning operation. Additionally, since the cleaning brush is in direct contact with the inner wall and bottom of the toilet, bacteria inevitably remain on it. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning robotic arm with a wide cleaning range and no contact with the area to be cleaned.

[0005] To achieve the above objectives, this utility model provides a contactless cleaning robotic arm, comprising a first rotating arm, a second rotating arm, a third rotating arm, an operating arm, and a common tube. The first rotating arm has a first rotary drive and a second rotary drive respectively at its two ends. The first rotary drive can drive the first rotating arm to rotate around a first axis. The first end of the second rotating arm is rotatably connected to the second end of the first rotating arm. The second rotary drive can drive the second rotating arm to rotate around a second axis, which is perpendicular to the first axis. The second end of the second rotating arm has a third rotary drive. The first end of the third rotating arm is rotatable from the second end of the second rotating arm. The system is connected to a third rotating drive unit that drives a third rotating arm to rotate around a third axis, which is parallel to the second axis. An operating rotating drive unit is provided at the second end of the third rotating arm. The first end of the operating arm is rotatably connected to the second end of the third rotating arm. The operating rotating drive unit drives the operating arm to rotate around an operating axis, which is perpendicular to the third axis. A cleaning nozzle is provided at the second end of the operating arm, which can spray water and / or blow air. The first end of the common pipe is used to connect to a water source and / or an air source. The second end of the common pipe is connected to the cleaning nozzle. The middle part of the common pipe is connected to the first rotating arm, the second rotating arm, the third rotating arm, and the operating arm, respectively.

[0006] As can be seen from the above solution, by setting up multiple rotating arms, even if the cleaning robotic arm is placed on the outer wall of the toilet body, the operating arm can still move flexibly to above the seat or toilet skirt, effectively increasing its range of motion. Simultaneously, the cleaning nozzle has both rinsing and drying functions, allowing for sequential cleaning and drying of the seat or toilet skirt. By using a shared pipe, cleaning water and drying share a single conduit, which helps save space and piping.

[0007] A further embodiment is that the first rotary drive component includes a motor, a drive gear, a driven gear, a planetary carrier, and an upper cover. The drive gear is mounted on the drive shaft of the motor, and the upper cover is mounted on the motor. Multiple teeth are provided on the inner peripheral wall of the upper cover. The planetary carrier is positioned between the upper cover and the motor. Mounting posts and a first power rod are respectively provided on both sides of the planetary carrier. The driven gear is connected to the mounting posts and meshes with the drive gear and the teeth. The first power rod extends upward through the upper cover. The motor drives the driven gear and the planetary carrier to rotate through the drive gear, thereby driving the first power rod to rotate.

[0008] A further option is that the structures of the second rotary drive, the third rotary drive, and the operating rotary drive are all the same as the structure of the first rotary drive.

[0009] A further embodiment is that the first rotating arm is provided with a first lug, a first mounting part, and a first mounting groove. The first mounting part and the first mounting groove are respectively located at both ends of the first rotating arm, and the first lug is located between the first mounting part and the first mounting groove. The first mounting part is fixedly connected to the first power rod, the first lug protrudes from the bottom wall of the first rotating arm, and the second rotation drive is located in the first mounting groove. The second power rod of the second rotation drive penetrates through the bottom of the first mounting groove.

[0010] A further embodiment is that the second rotating arm is provided with a second lug, a second mounting part, and a second mounting groove. The second mounting part and the second mounting groove are respectively located at both ends of the second rotating arm, and the second lug is located between the second mounting part and the second mounting groove. The second mounting part is fixedly connected to the second power rod, and the second lug protrudes from the bottom wall of the second rotating arm. The third rotary drive component is located in the second mounting groove, and the third power rod of the third rotary drive component penetrates through the bottom of the second mounting groove.

[0011] A further embodiment is that the third rotating arm is provided with a third mounting part and a third mounting groove, which are respectively located at both ends of the third rotating arm; the third mounting part is fixedly connected to the third power rod, and the operating rotation drive component is located in the third mounting groove, with the operating power rod of the operating rotation drive component protruding from the third mounting groove.

[0012] A further option is to provide a fourth mounting part on the first end of the operating arm, which is fixedly connected to the operating power rod, and the cleaning nozzle is arranged inside the second end of the operating arm along the length of the operating arm.

[0013] A further embodiment is that the first rotating arm has a first groove, a first through hole, and a second through hole, with the two ends of the first groove communicating with the first through hole and the second through hole, respectively; the second rotating arm has a second groove, a third through hole, and a fourth through hole, with the two ends of the second groove communicating with the third through hole and the fourth through hole, respectively; the third rotating arm has a third groove, a fifth through hole, and a sixth through hole, with the two ends of the third groove communicating with the fifth through hole and the sixth through hole, respectively; the operating arm has an operating groove and a seventh through hole, with the seventh through hole located at the first end of the operating arm and communicating with the operating groove; a common pipe is respectively installed in the first through hole, the first groove, the second through hole, the third through hole, the second groove, the fourth through hole, the fifth through hole, the third groove, the sixth through hole, the seventh through hole, and the operating groove.

[0014] As can be seen from the above scheme, with the above settings, the common pipe is directly placed in multiple through holes and multiple grooves, and it can be firmly fixed without additional fasteners, thereby effectively preventing the common pipe from coming loose from the rotating arm during the cleaning process.

[0015] A further solution is to install a sterilization module on the second end of the operating arm.

[0016] As can be seen from the above scheme, the above settings facilitate the disinfection and sterilization of the cleaned toilet seat or toilet skirt. Attached Figure Description
