Description

Technical Field

[0001] The utility model relates to the technical field of disinfection robots, in particular to a disinfection robot with an obstacle avoidance function. Background Art

[0002] A sweeping and disinfecting robot is an intelligent device that is commonly used for cleaning and disinfecting floors in hospitals, laboratories, offices, and other places. These robots combine the functions of sweeping robots and disinfection equipment, and can automatically cruise and clean the floor while releasing disinfectants or ultraviolet light and other technologies to kill pathogens such as bacteria and viruses. These robots are usually equipped with a variety of sensors, such as lidar, cameras, etc., to avoid obstacles during the cleaning process and ensure that all areas are covered. They may also have mapping functions that can remember and plan cleaning paths to improve cleaning efficiency.

[0003] In terms of disinfection, existing sweeping and disinfecting robots can use different technologies, including ultraviolet disinfection, spray disinfection, etc. Ultraviolet disinfection can kill microorganisms such as bacteria and viruses through radiation, while spray disinfection achieves the same effect by spraying disinfectants. The use of these robots can reduce the labor intensity of manual cleaning, improve cleaning efficiency, and ensure the standardization and consistency of the disinfection process.

[0004] However, the existing sweeping and disinfecting robots cannot disassemble the cleaning broom separately for cleaning or replacement. Therefore, when the broom needs to be replaced, the operation and maintenance are relatively complicated, time-consuming and laborious, and the service life of the sweeping and disinfecting machine is also reduced.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The outer wall of the slide bar 12 is sleeved with a second spring 14, one end of the second spring 14 is fixedly connected to the inside of the connecting plate 6, the other end of the second spring 14 is fixedly connected to the push plate 15, and the lower surface of the mounting plate 7 is fixedly connected to the broom 18;

[0031] Specifically, the slider 13 is slid to both sides, which drives the push plate 15 to compress the second spring 14. At the same time, the slide bar 12 can be pulled, which drives the hook 16 to rotate inside the mounting ring 5. In this process, the hook 16 releases the restriction on the fixing ring 11, and the mounting plate 7 slides outward. In this way, the broom 18 can be removed from the inside of the mounting ring 5. This makes the cleaning and replacement process of the broom 18 simple and quick.

[0032] This not only improves the practicality of the disinfection robot, but also extends its service life, because timely replacement and cleaning of the broom 18 can ensure cleaning effect and operating efficiency. At the same time, it makes the maintenance and care of the disinfection robot easier, helps to maintain its good working condition, improves the cleaning and disinfection effect, and thus ensures the hygiene and safety of the use environment.

[0033] Reference Figure 1 and Figure 3 The positioning assembly includes a sleeve 8, a first spring 9 is arranged inside the sleeve 8, one end of the first spring 9 is fixedly connected to the inside of the sleeve 8, the other end of the first spring 9 is fixedly connected to the top plate 10, and a push rod 17 is fixedly connected to the inside of the mounting ring 5, and the push rod 17 slides inside the sleeve 8;

[0034] Specifically, the push rod 17 slides into the sleeve 8 to push the top plate 10, so that the top plate 10 can compress the first spring 9, and then the first spring 9 can push the push rod 17 back by elastic force, so that the hook 16 can be better restricted to the outer wall of the fixing ring 11, thereby achieving the effect of strengthening the connection between the mounting ring 5 and the mounting plate 7.

[0035] Reference Figure 1 and Figure 4 A motor 20 is fixedly connected to the inside of the body 1, and a turntable 21 is fixedly connected to the output end of the motor 20; a movable plate 22 is slidably connected to the inside of the turntable 21, and a fan-shaped plate 23 is rotatably connected to the outer wall of the movable plate 22; the outer wall of the fan-shaped plate 23 is slidably connected to the inside of the body 1, and a pad 24 is slidably connected to the inside of the fan-shaped plate 23; the outer wall of the pad 24 is fixedly connected to a limiting block 25, and a fourth spring 27 is arranged inside the pad 24, one end of the fourth spring 27 is fixedly connected to the pad 24, and the other end of the fourth spring 27 is fixedly connected to the outer wall of the limiting block 25, and the outer wall of the limiting block 25 is slidably connected to the inside of the fan-shaped plate 23; a third spring 26 is arranged inside the fan-shaped plate 23; one end of the third spring 26 is fixedly connected to the inside of the fan-shaped plate 23, and the other end of the third spring 26 is fixedly connected to the outer wall of the pad 24;

[0036] When it is necessary to reduce the space occupied by the disinfection robot and reduce the impact of the collision, the motor 20 is started, and the motor 20 drives the turntable 21 to rotate. The rotation of the turntable 21 causes the movable plate 22 to pull the fan-shaped plate 23, so that the fan-shaped plate 23 slides into the interior of the body 1, thereby saving space. In this process, the pad 24 slides inside the fan-shaped plate 23 and is limited by the limit block 25 to limit its position. When the pad 24 collides with the wall, the pad 24 can compress the third spring 26.

[0037] This can reduce the force generated by the machine when it is hit, thereby mitigating the impact. At the same time, it can also help the robot itself avoid obstacles and improve the safety of the robot. By reducing the space occupied by the robot and mitigating the impact of collisions, this design ensures the safety of the disinfection robot during use and ensures that it can complete cleaning and disinfection tasks safely and effectively.

[0038] Working principle: When the broom 18 needs to be disassembled and replaced, the slider 13 is slid to both sides to drive the push plate 15 to compress the second spring 14, and at the same time, the slide bar 12 can be pulled to drive the hook 16 to rotate around the rotating shaft 19 inside the mounting ring 5, so that the hook 16 can release the restriction on the fixing ring 11, and then slide out of the mounting plate 7, so that the broom 18 can be disassembled from the inside of the mounting ring 5;

[0039] When it is necessary to reduce the space occupied by the disinfection robot and to buffer the impact of collision on the robot, the motor 20 drives the turntable 21 to rotate, so that the turntable 21 can pull the fan-shaped plate 23 through the movable plate 22, and then the fan-shaped plate 23 can be slid into the interior of the body 1, thereby saving space. At the same time, the pad 24 slides inside the fan-shaped plate 23, and the limit block 25 pushes the fourth spring 27 to be compressed, so that the limit block 25 can slide inside the pad 24 and the fan-shaped plate 23 to limit the position of the pad 24. When the pad 24 collides with the wall, the pad 24 can compress the third spring 26, thereby achieving the effect of reducing the force generated by the machine when it is hit, and at the same time, the machine itself can avoid obstacles, thereby improving the safety of the disinfection robot and ensuring the safe use of the disinfection robot.
