The specific disinfection mode comprises the following steps: sterilizing the air and the object surfaces by sterilizing personnel or automatic sterilizing machines through atomizing, spraying or scrubbing the sterilizing agents such as alcohol, hydrogen peroxide, chlorine-containing sterilizing agents, peracetic acid and the like.
However, these chemical disinfectants on the one hand can directly damage human bodies and equipment, and disinfection byproducts can also increase the risk of cancer of human bodies, so that the chemical disinfectants need to be used under unmanned conditions, and due to the short action time of the chemical disinfectants, the problem that bacteria are easy to leak during a disinfection interval in public transportation means and public places (hospitals, schools, banks, airports, stations and the like) with large personnel flow is solved.
In addition, most of atomization disinfection machines are mainly used for atomizing hydrogen peroxide, hypochlorous acid and the like into the air and sterilizing by diffusion, so that the atomization disinfection machines cannot be used under the condition of people; the photocatalysis sterilizer mainly combines ultraviolet irradiation with photocatalysis, is not suitable for killing bacteria gas due to low photochemical conversion efficiency, has low sterilization efficiency, is difficult to meet sterilization requirements, and can generate ozone to cause secondary pollution in the use process of a 254nm ultraviolet lamp.
CN109107381a discloses a photocatalytic air purifier with self-purifying capability, which comprises a power supply, a controller, a shell, a coarse filter screen, a high-efficiency filter screen, an activated carbon screen, a photocatalytic screen, an ultraviolet lamp positioned behind the photocatalytic screen, and a first fan positioned behind the ultraviolet lamp, wherein the coarse filter screen, the high-efficiency filter screen, the activated carbon screen, the photocatalytic screen, the ultraviolet lamp and the first fan are sequentially arranged in parallel; the filter screen disinfection and sterilization device and the active carbon drying device are also included. The filter screen sterilizing device can kill bacteria growing on the filter screen, and the frequency of manually cleaning the filter screen is reduced; the activated carbon drying device can remove the moisture absorbed by the activated carbon, so that the activated carbon recovers part of the activity.
CN213789117U discloses a portable spray sterilizer, which comprises a tank body, wherein the upper end of the tank body is provided with a water inlet and a spray opening, the water inlet is communicated with a water tank in the tank body through a pipeline, the water tank is arranged in an open way, an ultrasonic atomizer is arranged in the water tank, and an ozone generator is arranged in the tank body and outside the water tank; the photocatalytic screen plate is arranged in the box body and at the spraying opening, the blowing fan is arranged in the spraying opening, and the blowing fan, the photocatalytic screen plate and the ozone generator are electrically connected with a power supply. The scheme provides a disinfection system without adding chemical disinfectant, thereby saving the adding cost of the disinfectant.
Therefore, the disinfection purifier in the prior art has the problems of short duration, no need of using an unmanned space, harm of byproducts to human bodies and the like, so that the problem of harm to human bodies can be solved while the continuous disinfection and purification is ensured, and the technical problem of urgent need to be solved at present is also ensured.
