Description

Technical Field

[0001] The present invention relates to the field of public health technology, and in particular to a device and method for fully automatic disinfection of handrails. Background Art

[0002] In the existing technology, with the continuous development and research and exploration of human society, more and more viruses and bacteria have been discovered by humans. At the same time, some viruses and bacteria have spread among humans, seriously affecting human life safety. At the same time, as the scope of human activities gradually expands, the spread of viruses among humans is also accelerated. Therefore, there is an urgent need for a device that can disinfect places that people have contacted in time and kill the virus before it begins to spread, especially in some public places with large traffic such as social welfare institutions and nursing homes. In order to facilitate people's movements, these places will add handrails in some passages, and different groups of people will not Inadvertent contact with the handrail, when there are bacteria and viruses on the handrail, will spread through contact, especially when severe infectious diseases occur, it is very important to disinfect the handrails regularly, quantitatively and comprehensively. In the existing technology, the cleaning of the handrails is mainly based on manual wiping, and it is not possible to achieve regular, quantitative and full coverage disinfection, resulting in untimely and incomplete disinfection. The disinfection methods of using machine spray disinfection and mobile disinfection robots have the problems of dead corners of disinfection and cannot achieve timely and rapid disinfection. Therefore, a disinfection method and equipment for handrails are needed, so that the handrails can be disinfected regularly, quantitatively and fully covered.

[0003] The Chinese invention patent with application number: 202010677878.4 discloses a disinfectant wiping mechanism for an escalator handrail disinfection device, which belongs to the field of public health technology. It solves technical problems such as incomplete disinfection of existing escalators. The escalator handrail disinfection device includes a shell to which a liquid storage tank is fixed, and the disinfectant wiping mechanism includes a nozzle rack and a wiping rack installed in the disinfection chamber of the shell near the rear end and arranged sequentially from the outside to the inside. A plurality of nozzles are provided on the nozzle rack, and a wiping piece is fixed on the wiping rack. The wiping piece includes a straight strip segment and two arc segments matching the two ends of the handrail. A liquid extraction mechanism is provided between the liquid storage tank and the nozzle, which can be driven by the movement of the handrail to extract the disinfectant in the liquid storage tank and transport it to the nozzle for spraying. However, the disinfectant wiping mechanism of the handrail disinfection device of this escalator has a relatively complex structure. It can only disinfect the escalator, but cannot drive the equipment to automatically disinfect the handrail. It cannot fully cover the disinfection area, resulting in dead corners for disinfection. It cannot ensure that the wiping component is always in contact with the handrail, resulting in poor disinfection effect. It cannot achieve the timed and quantitative disinfection tasks of the handrail and the role of emergency avoidance. Summary of the invention

[0055] Among them, the wiping cleaning component can be installed with a rag with disinfectant according to usage requirements.

[0056] Working principle:

[0057] The handheld mobile terminal equipped with a background data management system can control the equipment and view the disinfection status of the armrest 2 in real time, count the disinfection data, and make the disinfection data visualized and quantifiable. The device for fully automatic disinfection of the armrest 2 is a professional disinfection equipment with a communication function. The disinfection function is realized through the internal UVC ultraviolet lamp 14, which is an important part of the disinfection work. The mobile disinfection on the armrest 2 is completed by the motion control component. The main control system box 22 controls the drive motor 4 to drive the active wheel mechanism 5 to move, so that the equipment can walk on the track of the armrest 2, so as to achieve the purpose of disinfecting the entire armrest 2. During the movement, wiping cleaning components are installed on both sides of the equipment. The wiping cleaning components use its elastic structure to achieve a close fit between the wiping blade 18 or the rag and the outer surface of the armrest 2, so as to achieve the purpose of cleaning the surface of the armrest 2 during the movement. The sensor system components include a human infrared sensor 19, a laser obstacle avoidance sensor 20 and an anti-fall sensor 21, among which the human body The infrared sensor 19 is used to detect and count the number of times the human body contacts the handrail 2. When the detected and counted number of human body contacts reaches the system preset number value, the device will disinfect the entire handrail 2, that is, it realizes the quantitative disinfection of the handrail 2. Among them, the equipment also has the function of timed disinfection, that is, when the quantitative disinfection value is not reached within a timed disinfection cycle, the handrail 2 disinfection device will perform timed disinfection. Timed disinfection and quantitative disinfection are complementary. Quantitative disinfection takes precedence over timed disinfection. After a quantitative disinfection is completed, the timing cycle is started. Within a cycle, if the quantitative disinfection value is not reached, the timed disinfection task is performed when the timed disinfection cycle comes, otherwise quantitative disinfection is performed, and the whole process is analogous. The function of the anti-fall sensor 21 is to prevent the handrail 2 disinfection device from detaching from the handrail 2 and causing damage to the device. The laser obstacle avoidance sensor 20 is used to detect obstacles in the forward direction of the device so that the device can brake in time. Through the sensor system components, the timed and quantitative disinfection tasks of the handrail 2 and the emergency avoidance functions can be realized.
