Abstract
The invention discloses an automatic control real-time disinfection and atomization device for an elevator, a disinfection method of the device and a disinfectant adding method of the device.
Description
Technical Field
The invention relates to a disinfection and atomization device for an elevator, a disinfection method of the disinfection and atomization device, and a disinfectant adding method of the disinfection and atomization device, in particular to an automatic control real-time disinfection and atomization device for an elevator, a disinfection method of the disinfection and atomization device, and a disinfectant adding method of the disinfection and atomization device.
Background
In a closed space, when bacteria or viruses are generated, disinfection is generally performed rarely at present, or disinfection is performed at intervals, and if new bacteria and viruses exist after a period of time passes after disinfection, timely disinfection is difficult to perform. The buttons in the elevator, the elevator wall and the ground can be adhered with bacteria, viruses and the like, and the bacteria, the viruses and the like can not be killed in time.
At present, disinfection methods of elevators mainly comprise disinfection liquid, ozone, ultraviolet rays and air filtration, and human body detection mainly comprises infrared detection (conventional heat release infrared detection) and pressure detection laid on the ground. The inside of the elevator is mainly used for killing bacteria or viruses by detecting a human body, automatically or manually controlling and spraying disinfectant, direct or indirect ultraviolet rays, ozone and the like when no human exists.
The above sterilization method has the following disadvantages:
(1) the disinfection can not be carried out in real time, newly generated bacteria or viruses and the like can not be killed and killed immediately, and the transmission path can not be cut off immediately, so that the infection between people is easy to cause;
(2) using manual controls such as: the safe high-speed medical elevator with the application number of 201721117667.5 is characterized in that an operating button is arranged beside a spray head, the operating button starts the spray head to spray disinfection liquid into a lift car, the button needs to be manually operated, the use is inconvenient, and secondary pollution is possible to the button;
(3) the sterilization mode has certain defects in the prior air filtration sterilization, ultraviolet ray, disinfectant and ozone sterilization, the ultraviolet ray direct sterilization mode adopts the ultraviolet ray with specific intensity to irradiate a space for a certain time to kill bacteria or viruses, when a person is in the elevator, an ultraviolet lamp and the like cannot be started, because the ultraviolet ray is harmful to the human body, when the person breathes out harmful bacteria or viruses in the elevator, the harmful bacteria or viruses cannot be killed in time, and when a plurality of persons are in the elevator, cross infection is caused; the ultraviolet indirect sterilization mode is that an air circulating device is arranged at the top in an elevator, and the air in the circulating device is irradiated by ultraviolet rays for sterilization, so that the problem exists that the circulating device has flow limitation, bacteria or viruses carried by droplets generated by exhalation of a human body cannot be immediately sterilized, the bacteria or viruses are difficult to be absorbed into a circulating air duct at the top and fall to the ground due to the influence of gravity, and the ultraviolet rays need to be irradiated for a certain time for sterilization, so that the real-time sterilization requirement cannot be met; the traditional disinfectant has large taste and can not be used by people generally. Can not be directly sprayed on people, and when no people is detected, the disinfection is carried out, and the ventilation is carried out for a period of time, so that suitable people can enter(ii) a The traditional disinfection mode also comprises ozone which is a strong oxidant and has special odor, so that the ozone can not be directly used for people, is only suitable for disinfecting elevators when no one is in use, and adopts 20mg/m3Ozone with concentration is acted for 30min, the killing rate of natural bacteria reaches more than 90%, the concentration requires great harm to human bodies, and the ozone can enter after at least 30min after disinfection;
(4) detect human body and adopt the heat release infrared sensor usually, can only detect the human body of activity, when personnel are static, whether someone exists can not be judged to this sensor, whether someone in the elevator is detected to the mode that the pressure sensor was laid to the part adoption ground in the elevator, like application number 201610217084.3's a novel elevator, when pressure sensor detected pressure value in the elevator and is initial value, nobody used the elevator promptly, control ultraviolet sterilizing lamp work this moment, disinfect to the elevator. The mode is suitable for installation of an elevator manufacturer, subsequent installation is inconvenient, and if the whole ground is detected, the mode is difficult to modify and wire distribution and requires a cable to be connected to a controller;
(5) the replacement of the disinfectant is in doubt, how to place the disinfectant is basically not involved, and particularly when a disinfecting device is arranged at the top, people can hardly touch the top of the elevator when climbing without an external tool, and the disinfectant is difficult to add;
(6) the safety can not be guaranteed, and the use safety and the equipment safety need to be guaranteed.
