Abstract
Description
Technical Field
[0001] This utility model relates to the field of robotics technology, specifically to a cleaning mechanism for a bathroom cleaning robot. Background Technology
[0002] In the existing bathroom cleaning field, some cleaning equipment uses a cleaning mechanism driven by a synchronous belt. This mechanism mainly consists of a synchronous belt, a push rod mounted on a lifting rail, and a cleaning actuator head located at the end of the push rod. In practical applications, this structure is commonly found in some bathroom cleaning robots or semi-automatic cleaning equipment. In scenarios such as home bathrooms and hotel bathrooms, the goal is to use the synchronous belt to drive the push rod, enabling the cleaning actuator head to move in both vertical and horizontal directions, thereby cleaning toilets, sinks, and other sanitary fixtures.
[0003] However, this existing technology has many drawbacks. In terms of motion stability, when the cleaning head extends to its end for cleaning, the change in mass distribution and shift in the center of gravity severely affect the overall motion stability of the mechanism, frequently causing jamming. This not only reduces cleaning efficiency but also results in incomplete cleaning. Regarding transmission accuracy, synchronous belt drives have significant shortcomings, making it difficult to guarantee the precision of each transmission. This causes deviations in the positioning and movement of the cleaning head, preventing accurate cleaning of all parts of the sanitary fixtures. As the cleaning head rises, falls, and moves forward and backward, the tubing at its end is prone to tangling and pulling, increasing motion resistance. In severe cases, this can completely obstruct the entire motion mechanism, preventing normal operation and significantly hindering the smooth progress of cleaning work. Utility Model Content
[0004] The purpose of this invention is to provide a cleaning mechanism for a bathroom cleaning robot to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning mechanism for a toilet cleaning robot, comprising: guide rails and telescopic push rods, wherein the telescopic push rods and the two guide rails are arranged in a parallel manner; a movable bracket, one end of which is movably mounted on the two guide rails and connected to the telescopic end of the telescopic push rod, thereby driving the movable bracket to move along the direction of the two guide rails via the telescopic push rods; an opening structure, which is movably mounted on the movable bracket in a vertical direction; and a cleaning structure, which is movably mounted on the movable bracket in a vertical direction, wherein the cleaning structure and the opening structure are parallel to each other.
[0006] In one feasible implementation, the cover opening structure includes: a cover opening push rod, the fixed end of which is installed at the top of the inside of the movable bracket; a cover opening drag chain, the stationary end of which is disposed on one side of the outer wall of the movable bracket; and an abutment component, which is connected to the bottom ends of the cover opening push rod and the cover opening drag chain respectively.
[0007] In one feasible implementation, the cleaning structure includes: a cleaning push rod, the fixed end of which is installed at the top of the interior of the movable bracket; a cleaning cable chain, the stationary end of which is fixedly disposed on the outer wall of the other side of the movable bracket; and a rinsing assembly, which is connected to the bottom ends of the cleaning push rod and the cleaning cable chain respectively.
[0008] In one feasible implementation, the abutment component includes: a connector, which is connected to the telescopic end of the cover-opening push rod and the movable end of the cover-opening drag chain, and has an opening space; a flap, which is hinged and rotatably installed in the opening space of the connector; and a suction cup, which is fixedly disposed on the bottom surface of the flap.
[0009] In one feasible implementation, the rinsing assembly includes: a rinsing head, which is fixedly mounted on the telescopic end of the rinsing push rod and the movable end of the rinsing cable chain; and a spray head, which is mounted on the bottom end of the rinsing head.
[0010] In one feasible implementation, the nozzle is configured as a rotatable atomizing nozzle.
[0011] Compared with existing technologies, the beneficial effects of this utility model are: the cleaning mechanism of this bathroom cleaning robot achieves a more stable and efficient cleaning effect. The combination of guide rails, telescopic push rods, and a moving bracket allows the moving bracket to move smoothly along the guide rail direction under the drive of the telescopic push rods. Compared with the original synchronous belt drive, this effectively improves the problem of center of gravity shift and enhances movement stability. During the cleaning process, once the moving bracket reaches the designated position, the opening and cleaning structures vertically mounted on it can be operated accordingly. The opening and cleaning chains respectively protect the internal pipelines of the opening and cleaning structures, preventing entanglement and ensuring smooth operation of all components. With this structural design, the device effectively solves the problems of instability and high movement resistance inherent in synchronous belt drives, ultimately enabling more stable and efficient cleaning of toilets and urinals in the bathroom cleaning robot, effectively removing stubborn stains, reducing cleaning dead spots, and achieving highly efficient cleaning of the bathroom.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a cleaning mechanism for a bathroom cleaning robot, comprising: a guide rail 1, a telescopic push rod 2, a movable support 3, a cover opening structure, and a cleaning structure. The telescopic push rod 2 and the two guide rails 1 are arranged parallel to each other. One end of the movable support 3 is movably mounted on the two guide rails 1 and connected to the telescopic end of the telescopic push rod 2. The telescopic push rod 2 drives the movable support 3 to move along the direction of the two guide rails 1. The cover opening structure is movably mounted on the movable support 3 in a vertical direction. The cleaning structure is movably mounted on the movable support 3 in a vertical direction, and the cleaning structure and the cover opening structure are parallel to each other.
[0019] It should be noted that when the cleaning structure of this bathroom cleaning robot is working, the telescopic push rod 2 first begins to move. Since the telescopic push rod 2 is parallel to the two guide rails 1, the extension and retraction of the telescopic push rod 2 will drive the moving bracket 3 to move along the direction of the two guide rails 1. When the moving bracket 3 moves to the corresponding position, it begins to perform the lid opening operation. The lid opening structure moves vertically on the moving bracket 3 until it reaches the position where the toilet lid or other lids need to be opened, and completes the lid opening action in cooperation with the telescopic push rod 2. If cleaning is required, the cleaning structure begins to operate, also moving vertically on the moving bracket 3, and performing cleaning operations at the appropriate position. The moving bracket 3 can again be driven by the telescopic push rod 2 to move along the direction of the guide rails 1. Combined with the vertical movement of the cleaning structure, cleaning work can be carried out on different positions. The entire cleaning process completes the cleaning-related workflow of the bathroom cleaning robot through the coordinated movement of the cleaning structure, the lid opening structure, and the cleaning robot.
[0020] In some examples, the opening structure includes: an opening push rod 4, an opening drag chain 5, and an abutment assembly. The fixed end of the opening push rod 4 is installed at the top inside the movable bracket 3; the stationary end of the opening drag chain 5 is located on one side of the outer wall of the movable bracket 3; and the abutment assembly is connected to the bottom ends of the opening push rod 4 and the opening drag chain 5, respectively.
[0021] It should be noted that when the cleaning mechanism of the toilet cleaning robot needs to perform the lid-opening action, firstly, the telescopic push rod 2 pushes the moving bracket 3 to move above the toilet seat. Then, the lid-opening push rod 4, installed at the top of the moving bracket 3, begins to operate. After the lid-opening push rod 4 is activated, its telescopic end begins to extend. As the lid-opening push rod 4 extends, the connected abutment component will move towards the toilet seat. During the displacement of the abutment component, the movable end of the lid-opening drag chain 5 will extend or curl accordingly with the movement of the abutment component. The lid-opening drag chain 5 is used to cover the wires in the cleaning robot and the lid-opening mechanism to ensure that the connected wires and other wiring harnesses are not excessively pulled or tangled during the movement of the abutment component. The abutment component moves downward continuously under the drive of the lid-opening push rod 4 until it contacts the lid or other object that needs to be opened. The lid is then held in place by the suction function of the abutment component. Finally, the lid-opening operation is completed through the cooperation of the telescopic push rod 2 and the lid-opening push rod 4. The lid-opening function of the cleaning structure is realized through the coordinated operation of the lid-opening push rod 4, the lid-opening drag chain 5, and the abutment component.
[0022] In some examples, the cleaning structure includes a cleaning push rod 6, a cleaning cable chain 7, and a rinsing assembly. The fixed end of the cleaning push rod 6 is installed at the top inside the movable bracket 3; the stationary end of the cleaning cable chain 7 is fixedly installed on the outer wall of the other side of the movable bracket 3; and the rinsing assembly is connected to the bottom ends of the cleaning push rod 6 and the cleaning cable chain 7, respectively.
[0023] It should be noted that after the toilet seat is opened via the opening mechanism, the telescopic push rod 2 moves the movable bracket 3 to above the toilet, and then the cleaning push rod 6 begins to operate. The telescopic end of the cleaning push rod 6 extends or retracts. As the telescopic end of the cleaning push rod 6 moves, the connected flushing assembly is displaced vertically. The movable end of the cleaning chain 7 extends or curls accordingly as the flushing assembly moves. The clean water and cleaning agent sprayed by the flushing assembly are provided through the pipeline connecting the cleaning robot and the flushing assembly. The cleaning chain 7 effectively protects the pipeline connected to the flushing assembly, preventing it from becoming tangled, knotted, or excessively stretched during the movement of the flushing assembly. Driven by the cleaning push rod 6, the flushing assembly moves continuously downward until it reaches the area that needs cleaning. Upon reaching the designated position, the flushing assembly begins to operate, performing a flushing operation on the target area. The extension and retraction of the cleaning push rod 6 allows for flushing at different heights of the toilet, achieving the cleaning function. The cleaning work is successfully completed thanks to the close cooperation between the cleaning push rod 6, the cleaning chain 7, and the flushing assembly.
[0024] In some examples, the abutment components include: a connector 8, a flap 9, and a suction cup 10. The connector 8 is connected to the telescopic end of the cover-opening push rod 4 and the movable end of the cover-opening drag chain 5, and has a movable space. The flap 9 is mounted in the movable space of the connector 8 via a hinge. The suction cup 10 is fixedly set on the bottom surface of the flap 9.
[0025] It should be noted that when performing the lid-opening task, firstly, the lid-opening push rod 4 begins to work, and its telescopic end extends. The connecting piece 8 moves vertically as the lid-opening push rod 4 extends, and with the movement of the connecting piece 8, the flap 9 installed in its movable space also moves. This continues until the suction cup 10, which can be a miniature electric suction cup, adheres to the toilet seat. Then, the lid-opening push rod 4 and the telescopic push rod 2 begin to retract, causing the flap 9 to flip via a hinge. Then, the lid-opening push rod 4 and the telescopic push rod 2 begin to perform corresponding actions, driving the connecting piece 8, the flap 9 adhering to the toilet seat, and the suction cup 10 together to move in the designated direction, thereby realizing the operation of lifting the toilet seat.
[0026] In some examples, the rinsing assembly includes a rinsing head 11 and a nozzle 12, wherein the rinsing head 11 is fixedly mounted on the telescopic end of the rinsing push rod 6 and the movable end of the rinsing cable chain 7, respectively; and the nozzle 12 is mounted on the bottom end of the rinsing head 11.
[0027] It should be noted that when the cleaning task begins, the cleaning push rod 6 is activated first, and its telescopic end begins to extend. As the cleaning push rod 6 extends and retracts, the cleaning head 11 moves vertically along its trajectory. When the cleaning head 11 moves to the position that needs cleaning, the nozzle 12 installed at the bottom of the cleaning head 11 starts to work, spraying cleaning liquid or water onto the target cleaning area. The cleaning push rod 6 drives the cleaning head 11 to move in different positions, and the nozzle 12 sprays continuously to complete the cleaning operation of the bathroom facilities. This is achieved smoothly through the coordinated operation of the cleaning push rod 6, the cleaning chain 7, the cleaning head 11, and the nozzle 12.
[0028] In some examples, the nozzle 12 is configured as a rotatable atomizing nozzle 12. The rotatable atomizing nozzle 12 allows it to spray cleaning fluid or water from multiple angles. When cleaning toilets and other sanitary fixtures, it can cover areas that are difficult for ordinary nozzles 12 to reach, such as corners, edges, and internal curved surfaces of the toilet, reducing cleaning dead spots, improving overall cleaning effectiveness, and ensuring effective cleaning. The atomizing nozzle 12 atomizes the cleaning fluid, increasing the contact area between the cleaning fluid and stains, allowing the cleaning fluid to be more evenly distributed on the surface of the object being cleaned, and more fully exerting its cleaning effect. The rotatable function allows the cleaning fluid to impact stains from different angles, enhancing the ability to remove stubborn stains, making toilets, urinals, etc., cleaner. The atomized cleaning fluid can more efficiently cover the cleaning area, and the rotating nozzle 12 can also spray the cleaning fluid precisely, avoiding waste. While achieving the same cleaning effect, it can reduce the amount of cleaning fluid and water used, thus reducing cleaning costs and conforming to environmental protection principles.
