Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a multi-environmental adaptable toilet cleaning robot that can be adapted to cleaning toilets of different sizes. Background Technology

[0002] Currently, traditional manual cleaning methods for household bathrooms have prominent problems such as low efficiency, incomplete coverage, and high safety risks. On the one hand, for special groups such as the elderly and pregnant women, manual cleaning of toilet bowls requires frequent bending over and vigorous scrubbing, which is labor-intensive, and the wet bathroom floor is slippery and prone to causing falls. On the other hand, the inner wall of the toilet bowl has a complex curved structure with many dead corners such as water traps and edge gaps. Manual cleaning relies on experience and operating techniques, making it difficult to completely remove dirt, which can easily breed bacteria and affect hygiene and health.

[0003] While some toilet cleaning devices exist in the existing technology, they still have significant drawbacks: The "A Cleaning Tool for Dead Corners of Public Toilets" with publication number CN215016645U, although it reduces the workload of cleaning staff through a specific structure, still requires manual hand operation and does not get rid of the dependence on manpower. Moreover, the cleaning range and angle of the tool are limited by the hand operation.

[0004] The "adaptive cleaning toilet" with the publication number CN212956821U adopts an integrated design of cleaning module and toilet. Although it can achieve a certain degree of automatic cleaning, it requires a complete renovation of the toilet and cannot be adapted to the existing toilets already installed in the home. The renovation cost is high and the applicability is poor, making it difficult to promote in ordinary households.

[0005] Other automated cleaning equipment may not be thoroughly cleaned due to the inflexible adjustment of the cleaning head angle and position, resulting in incomplete cleaning of toilet bowl corners (such as the bottom of the water trap and the corners of the edges); or due to its complex structure and high manufacturing cost, it may not meet the economic needs of household users; or due to the lack of waterproof and corrosion-resistant design, it may have a short service life in the humid environment of the bathroom. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a multi-environmentally adaptable intelligent toilet cleaning robot. This robot eliminates the dependence on manual hand operation, realizes full automation of toilet cleaning, and reduces the labor intensity and safety risks for the elderly, pregnant women and other groups. At the same time, it has good environmental adaptability and can be adapted to household toilets of different depths, widths and shapes without modifying existing toilets. Through the adjustment of the multi-angle cleaning mechanism, it can achieve full coverage and thorough cleaning of the inner wall of the toilet.

[0007] This utility model relates to a multi-environmentally adaptable toilet cleaning robot, comprising a shell, a telescopic module, and a cleaning module; the telescopic module is connected between the shell and the cleaning module and is used to push the cleaning module outward; the cleaning module includes a sliding frame, a rotating brush head, and a brush head translation mechanism; the sliding frame is rotatably connected to the telescopic module; the rotating brush head is mounted on the sliding frame and can be translated along the sliding frame under the drive of the brush head translation mechanism.

[0008] In some possible implementations, the telescopic module includes an inner support panel, an outer support panel, a scissor mechanism disposed between the two support panels, and a ball screw module for actuating the scissor mechanism; the scissor mechanism includes several pairs of scissor arms that are hinged to each other to form an X structure, one end of the scissor arm is hinged to a support panel, and the other end is connected to another support panel via a linear slide rail.

[0009] In some possible implementations, two parallel longitudinal guide rods are fixedly installed on both sides of the sliding frame, and a transverse guide rod is slidably connected between the two longitudinal guide rods. The rotating brush head is slidably connected to the transverse guide rod. The brush head translation mechanism is used to drive the transverse guide rod to slide along the longitudinal guide rod.

[0010] In some possible implementations, the brush head translation mechanism includes a stepper motor and a belt drive mechanism; the stepper motor is fixedly mounted on one end of the sliding frame, and the belt drive mechanism includes a driving pulley mounted on the motor output shaft, a driven pulley mounted on the other end of the sliding frame, and a synchronous belt cooperating between the driving pulley and the driven pulley; the end of the transverse guide rod is fixedly connected to the synchronous belt through a connecting fastener.

[0011] In some possible implementations, the rotating brush head includes a brush and a DC brushless motor that drives the brush to rotate; the transverse guide rod is provided with a brush adjustment servo that drives the rotating brush head to swing as a whole.

[0012] In some possible implementations, the outer casing includes a housing and a double-leaf hatch controlled to open and close by a servo motor.

Detailed Implementation

[0024] like Figure 1 The illustration shows a multi-environmentally adaptable toilet cleaning robot, comprising a shell 1, a telescopic module 1, and a cleaning module 3. The telescopic module 1 is fixed at one end to the shell 1 and connected at the other end to the cleaning module 3, for extending the cleaning module 3 outward. The cleaning module 3 includes a sliding frame 8, a rotating brush head 9, and a brush head translation mechanism. The sliding frame 8 is rotatably connected to the telescopic module 1. The rotating brush head 9 is mounted on the sliding frame 8 and can translate along the sliding frame 8 under the drive of the brush head translation mechanism.

[0025] The outer casing 1 includes a housing and two double-leaf doors controlled by a servo motor. The two double-leaf doors are connected to the housing by hinges. The telescopic module 1 and the cleaning module 3 are located inside the housing when not in operation. Waterproof sealing rings are provided at the seams of the outer casing 1, providing waterproof and dustproof performance. When not in operation, the telescopic module 1 and the cleaning module 3 are stored inside the housing, which can prevent internal components from being corroded by the humid environment and dust of the bathroom, thus protecting the core components. When in operation, the servo motor drives the double-leaf doors to open, providing space for the telescopic module 1 to push the cleaning module 3 outward, ensuring that the cleaning module 3 can extend smoothly and carry out cleaning operations. This balances protection and ease of operation, while the overall encapsulation structure also improves the aesthetics of the equipment and is suitable for the home bathroom environment.

[0026] like Figure 2 As shown, the telescopic module 1 includes an inner support panel, an outer support panel, a scissor mechanism disposed between the two support panels 4, and a ball screw module 5 for driving the scissor mechanism. The scissor mechanism includes two pairs of scissor arms 7 hinged together to form an X-structure. One end of each scissor arm 7 is hinged to one support panel 4, and the other end is connected to the other support panel 4 via a linear slide rail 6. Bearing seats and linear slide rails 6 are respectively provided on the opposite surfaces of the two support panels 4. The bearing seats are used to rotatably connect with the pivot at one end of each scissor arm 7, and the sliders of the linear slide rails 6 are used to connect to the other end of each scissor arm 7. The two sliders of the two sets of linear slide rails 6 are connected by a connecting rod, and the ball screw module 5 can synchronously drive the two pairs of scissor arms 7 by pushing the connecting rod. Figure 5 As shown, the ball screw module 5 includes a support seat I 5-1, a nut 5-2, a screw 5-3, a support seat II 5-4, a coupling 5-5, and a stepper motor 5-6. The stepper motor 5-6 is fixedly mounted on the inner support panel by a motor bracket. The screw 5-3 is supported between the support seat I 5-1 and the support seat II 5-4 by a bearing. The rotating shaft of the stepper motor 5-6 is connected to the screw through the coupling 5-5. The nut 5-2 is mounted on the screw 5-3 and connected to the connecting rod. When cleaning is required, the stepper motor 5-6 receives a control signal and starts. Its shaft drives the lead screw 5-3 to rotate through the coupling 5-5. Since the nut 5-2 is installed on the lead screw 5-3 and connected to the connecting rod between the sliders of the two sets of linear slide rails 6, the rotation of the lead screw 5-3 is converted into the linear movement of the nut 5-2 along the axis of the lead screw 5-3, which in turn drives the connecting rod to move synchronously. The connecting rod drives the slider of the linear slide rail 6 to slide along the slide rail, so that the two pairs of scissor arms 7 in the scissor mechanism, which are hinged to each other in an X structure, move synchronously. One end of the scissor arm 7 rotates around the bearing seat on the support panel, and the other end slides with the slider. Finally, the scissor mechanism between the inner support panel and the outer support panel gradually unfolds, and the cleaning module 3 connected to the outer support panel is pushed outward smoothly and accurately to the cleaning operation area inside the toilet bowl, providing the positional conditions for the cleaning module 3 to perform all-round scrubbing of the inner wall of the toilet bowl.

[0027] like Figure 3 As shown, the sliding frame 8 of the cleaning module 3 is connected to the outer support panel via a hinge 10. The outer support panel is equipped with a servo motor for driving the sliding frame 8 to unfold or retract. When cleaning is required, the outer support panel moves to a position close to the front end of the toilet bowl under the drive of the telescopic module 1. The servo motor drives the sliding frame 8 to rotate to a horizontal position, so that the rotating brush 3-4 is vertically downward. After cleaning is completed, the servo motor drives the sliding frame 8 to return to a position parallel to the support panel, so that the entire device is in a folded state, making it easy to store inside the outer shell 1.

[0028] like Figure 4 As shown, two parallel longitudinal guide rods 3-6 are fixedly installed on both sides of the sliding frame 8, and a transverse guide rod 3-2 is slidably connected between the two longitudinal guide rods 3-6; the transverse guide rod 3-2 is provided with connecting fasteners 3-5 at both ends, and the connecting fasteners 3-5 are provided with through holes that slide with the longitudinal guide rods 3-6; the rotating brush head 9 includes a brush 3-4 and a DC brushless motor 3-8 that drives the brush 3-4 to rotate; the transverse guide rod 3-2 is provided with a brush adjusting rudder that drives the rotating brush head 9 to swing as a whole. The brush adjustment servo motor 3-7 is mounted on the servo motor base, which is mounted on the horizontal guide rod. The DC brushless motor 3-8 of the rotating brush head 9 is fixedly mounted on the output end of the servo motor. Therefore, the rotating brush head 9 can swing at a certain angle under the drive of the brush adjustment servo motor 3-7. By adjusting the angle, the brush 3-4 can be made to closely fit the curved surface structure of the toilet bowl, which breaks through the limitation of fixed angle brush heads in cleaning complex curved surfaces and greatly improves the cleaning coverage of dead corner areas. The brush head of this cleaning module 3 uses a compound motion of "rotation + swing" to make the bristles exert multi-directional and dynamic force on the toilet bowl wall, which can more efficiently remove stubborn dirt.

[0029] The brush head translation mechanism drives the transverse guide rod 3-2 to slide along the longitudinal guide rod. To enable the rotating brush head 9 to move in the plane of the sliding frame 8, the cleaning module 3 further includes a brush head translation drive mechanism. This mechanism mainly includes a stepper motor 3-1 and a conveyor belt assembly. The stepper motor 3-1 is fixedly installed at one end of the sliding frame 8, and a drive pulley is provided on the motor output shaft. Two driven pulleys are provided at the other end of the sliding frame 8. The synchronous belt or conveyor belt set on both sides of the sliding frame 8 cooperates with the drive pulley and the driven pulleys to form a closed loop structure. The transverse guide rod 3-2 is fixed to the synchronous belt or conveyor belt through the connecting fastener 3-5. When the stepper motor 3-1 rotates, the drive pulley drives the conveyor belt to move in a cycle, thereby driving the transverse guide rod 3-2 to slide linearly along the longitudinal guide rod 3-6, realizing the longitudinal translation of the rotating brush head 9 on the sliding frame 8. At the same time, the rotating brush head 9 can be laterally adjusted by swinging laterally on the transverse guide rod 3-2 under the control of a servo motor. Through the above structural design, the rotating brush head 9 can achieve a composite motion of "longitudinal translation, rotation, and lateral oscillation." The stepper motor 3-1 controls the longitudinal translation, the brush adjustment servo motor 3-7 controls the brush head oscillation angle, and the DC brushless motor 3-8 drives the brush 3-4 to rotate at high speed. This multi-degree-of-freedom motion allows the brush 3-4 to closely conform to the curved surface and edges of the toilet bowl, achieving comprehensive, thorough cleaning of the inner wall, bottom, and corner areas of the toilet bowl, significantly improving cleaning efficiency and environmental adaptability.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
