Description
Technical Field
The present application relates to an intelligent disinfection device; in particular to a built-in intelligent disinfection device for manned tools and a manned tool with the built-in intelligent disinfection device.
Background
Public transport systems such as buses, subways and the like are main travel tools in cities and are the most dense transportation tools for mobile people. As a public transport means with the most dense personnel in unit time and unit area, the public transport passengers and the subway passengers have the hidden trouble of being easy to cross-infect various infectious germs and viruses in the air-conditioned vehicle with strong tightness. Daily disinfection of public transport means is of great importance. Particularly, in the environment of outbreak of new crown epidemic situation, the disinfection of public transport means is more strict and more important, and all points which are frequently contacted and possibly contacted by passengers are disinfected from the ground to the seats and from the armrests to the windows; even the points that passengers can not touch are disinfected, so that the infectious viruses in the air are killed.
There are already well established technologies for cabin exterior disinfection, but there are still many short panels for cabin interior disinfection. The traditional bus disinfection mainly depends on 'manual wiping and disinfectant spraying', which brings health risks to vehicle maintenance personnel to a certain extent, and the strict execution of disinfection standards is difficult to ensure under the condition of physical fatigue of the vehicle maintenance personnel; and the disinfection inefficiency, if disinfect to a plurality of buses simultaneously, then need a plurality of vehicle maintainer to operate, in case personnel quantity is not enough, then intelligence is disinfected to the bus one by one, and the bus that does not disinfect is in long-time stall state, and is unable work, also influences public transport operation efficiency.
The ultraviolet disinfection is an environment-friendly disinfection mode without secondary pollution, can fully utilize the advantages of sealing and dust-free, can quickly disinfect buses from inside to outside, and is widely applied in the period of new crown epidemic situations. However, ultraviolet rays can be blocked, and the viruses in partial dead angles cannot be irradiated after the ultraviolet rays are blocked, so a large number of ultraviolet lamps are required to be arranged for disinfection, meanwhile, the service life of the ultraviolet lamps is generally 8000 hours, the ultraviolet lamps are used for disinfection at high frequency in an epidemic situation period, the ultraviolet lamps are high in replacement frequency, and the disinfection cost is very high; in addition, ultraviolet light disinfection is required in dark environment, is more used for subway rail transit vehicles, but is not suitable for buses.
During the new crown epidemic situation, a disinfection device similar to a humidifier is also produced and placed in a carriage, a disinfectant is volatilized to the space of the carriage after being vaporized, theoretically, dead-angle-free disinfection can be achieved, but the speed is extremely low, the bus disinfection time is too long under the condition that air does not flow, and normal operation cannot be achieved, so that the disinfection device basically has no use value, or can only be used under the condition that the bus is parked for a long time (such as during the outage at night).
The other bus disinfection method is ozone disinfection, which has high disinfection efficiency and good disinfection effect, but ozone has great environmental pollution, and if ozone remains in the bus, the ozone can also have adverse effects on human health.
