Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a disinfection robot. Background Technology

[0002] With the continuous development of technology, intelligent robots are being applied more and more widely in various fields. Especially driven by public health events such as the COVID-19 pandemic, disinfection and epidemic prevention have become a key focus of social attention. Traditional disinfection usually involves manual methods, gradually carrying out the disinfection work. This method incurs significant labor and time costs, and disinfection personnel face the risk of infection when performing disinfection work in medical facilities and public places with high traffic. Disinfection robots can effectively address these shortcomings, achieving unmanned disinfection while maintaining high precision and wide-area coverage, ensuring both disinfection efficiency and the safety of disinfection personnel.

[0003] Disinfection robots include atomizing disinfection robots and ultraviolet disinfection robots, among which atomizing disinfection robots are the most common in epidemic prevention applications. Atomizing disinfection robots atomize disinfectant to generate disinfectant gas, which is then rapidly diffused into the indoor space using the robot's pneumatic system. However, the limited detection range and spraying area of ​​the detector affect disinfection efficiency. For example, Chinese utility model patent CN2102287645U discloses an epidemic prevention robot, specifically including a lidar and a disinfection sprayer. It can detect the external environment and spray disinfectant through a disinfection mechanism, effectively eliminating viruses and bacteria and preventing their spread. However, the lidar is only located on one side of the robot, making it easily obstructed by obstacles during disinfection operations, and the disinfectant spray has a narrow spraying range.

[0004] Therefore, providing a disinfection robot with a wide detection range, extended spraying range, and simple structure to replace manual disinfection work is a research goal pursued by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a disinfection robot to solve the problems mentioned in the background art.

[0042] As an optional solution, the aforementioned detection device 2 is a laser detector 201, but it can also be replaced with other detection equipment as needed.

[0043] In the specific implementation process, in order to prevent the robot's movement from being hindered and unable to work properly, the aforementioned laser detector 201 adopts 6 detection ports to achieve 360° laser output, avoiding obstacles from affecting the laser detector 201's recognition of the surrounding area during the detection process, and ensuring that the disinfection robot does not deviate from the disinfection route. The aforementioned disinfection nozzles 302 are arranged in a ring on the outer shell 1, which can achieve 180° spraying. The overall shape of the aforementioned body is a frustum, which can lower the robot's center of gravity and improve the robot's movement stability, allowing the robot to move on slopes with larger angles.

[0044] Example 2

[0045] like Figure 1 , Figure 3 and Figure 4As shown, the disinfection robot in this embodiment differs from that in Embodiment 1 in that the liquid storage mechanism 4 includes a liquid storage tank 402, which includes a partition 405, a limiting block, and an annular tube 406. The partition 405 is fixedly connected to the liquid storage tank 402, the limiting block is detachably connected to the bottom of the liquid storage tank 402, and the annular tube 406 is interference-fitted with the limiting block. The partition 405 is a wave deflector with several small holes, and the annular tube 406 has several small holes. The outer shell 101 has a second window 103 relative to the liquid storage mechanism 4. The liquid storage mechanism 4 also includes a transparent baffle 401, a liquid inlet 403, a water pump 404, and an infusion pipe. The transparent baffle 401 is adapted to the second window 103 on the outer shell 101, which facilitates observation of the disinfectant content and convenient replenishment of disinfectant. The water pump 404 is connected to the disinfection nozzle 301 through an infusion pipe, and the infusion pipe is detachably connected to the annular tube 406.

[0046] As an optional option, the above-mentioned liquid storage tank 402 can be made of either polyethylene or stainless steel. Depending on the actual needs, it can also be replaced with other impact-resistant and corrosion-resistant materials.

[0047] As an optional solution, an inlet cap is provided at the aforementioned inlet 403, the inlet cap being adapted to the size of the aforementioned inlet 403 and threadedly connected.

[0048] As an optional solution, a rubber ring is provided between the infusion tube and the storage tank 402, and the infusion tube is connected to the rubber ring and the storage tank 402.

[0053] In specific operation, the aforementioned motion device 5 is driven by three Mecanum wheels. The ROS host computer controls the drive motors 502 of the three Mecanum wheels on the chassis to control the rotation speed and angle of the Mecanum wheels. Through the coordinated rotation of the Mecanum wheels, the disinfection robot can be controlled to rotate in place and move in various directions, achieving in-place turning and movement in any direction. The zero turning radius makes it suitable for high-precision pose adjustment and motion control. The aforementioned motion device 5, together with the aforementioned laser detector 201, can realize the robot's automatic movement. The aforementioned drive motor 502, ROS host computer, Mecanum wheels, and most of the electrical components... Source 503 is located inside the flat panel at the bottom of the disinfection robot to prevent damage from debris during the disinfection process. Pressing switch 6 on the outer casing 1 will automatically activate the automatic cruise function, avoiding obstacles and pedestrians. The automatic cruise route can be transmitted to the ROS host computer of the disinfection robot via interface 7. After the disinfection process is completed, the disinfection robot will automatically return to its initial position to prepare for the next disinfection. During operation, the disinfection robot can monitor its working status and battery level in real time, and automatically return to the charging station to recharge when the power is low. The disinfection robot can also record disinfection data for subsequent management and analysis.
