The harm of ultraviolet rays to human body is certain. No matter what kind of ultraviolet light it is, it is harmful to human body. The difference is nothing more than the length of action time, and different ultraviolet energy has different harm to human body.
Ultraviolet rays with long wavelength are less harmful to human body because of their low energy. The ultraviolet in the wave band mentioned in this paper belongs to long-wave ultraviolet A light, and its wavelength is between 3 15-400 nm. It can penetrate clouds and glass into rooms and cars, penetrate into the dermis of the skin, cause tanning, and is also the main cause of skin aging, wrinkles and skin cancer.
UVA can be subdivided into UVA-2 (320-340 nm) and UVA- 1 (340-400 nm). UVA- 1 has the strongest penetrating power, and can directly reach the dermis to make the skin tan, which is the most harmful to the skin, but it is also the most easily overlooked, especially in non-summer. In other words, the ultraviolet band is harmful to the human body.
At the same time, it is also mentioned in the instructions of the photocatalyst mosquito repellent lamp that the mosquito-trapping lamp of the photocatalyst mosquito repellent lamp emits ultraviolet rays with a wavelength of 360-380 nm, and uses the phototaxis of mosquitoes to attract mosquitoes to be dried or electrocuted;
This kind of mosquito killer is easy to cause serious secondary pollution. After mosquito carcasses are air-dried or electrocuted, a large number of germs will spread into the air and on the surface of objects. This is also an aspect of the harm of mosquito repellent lamp to human body.
Many mosquito lamps on the market are actually photocatalyst mosquito killers. This mosquito killer uses light, smell and comprehensive technology to kill mosquitoes. Mosquitoes find people through the smell of carbon dioxide emitted by the human body. When they feel the flow of carbon dioxide gas, they will fly to it immediately. Moreover, mosquitoes have phototaxis, and ultraviolet rays attract them.
Photocatalytic mosquito repellent is to attract mosquitoes by using their favorite ultraviolet rays. 360-degree illumination, coupled with micro-temperature effect, releases carbon dioxide and airflow, simulates the humid smell of carbon dioxide emitted by human body, and lures mosquitoes to fly. The fan stirs the surrounding air to form a vortex, so that mosquitoes who are used to flying with the airflow come with the wind. Once the mosquito is sucked into the trap window, it is difficult to escape the vortex formed by the fan, and it will be sucked to the bottom of the trap by the vortex of the fan until it dries to death.
Extended data:
Pay attention to methods to reduce injuries:
However, the influence of mosquito repellent lamp on human health is limited. As long as you pay attention to the method, you can reduce the harm. In life, we should also pay attention to light pollution.
Under normal circumstances, people are not present when the mosquito repellent lamp works, because the human body is much more attractive to mosquitoes than the mosquito repellent lamp, which will be explained in this general manual.
Therefore, the mosquito repellent lamp has a certain impact on the human body, but it is alarmist to say that it is harmful, because the mosquito repellent lamp can only work effectively when no one is around.
Try to turn on the mosquito repellent lamp when people are away, and don't turn it on all night when sleeping. This is not only bad for human body, but also reduces the effect of the mosquito repellent lamp.
To sterilize, there must be light. Under the existing technical conditions, the light used for photocatalysis can already range from ultraviolet to far infrared. However, with the increase of wavelength, the technical requirements are higher, and ultraviolet light belongs to a relatively low stage.
The product price is also cheaper. Therefore, the mosquito killer using ultraviolet light can be determined to be harmful to human body through ultraviolet light. Therefore, if you want to reduce the harm of mosquito-repellent incense lamps to human body, you can choose to turn on the mosquito-repellent incense lamps when no one is around, or choose mosquito-repellent incense lamps with better quality and less harm to human body on the market, or even adopt original methods such as mosquito nets, which can not only repel mosquitoes, but also protect your health.
At present, mosquito killers are mainly divided into electric shock mosquito killing and inhalation mosquito killing. The electric shock mosquito killer is that mosquitoes are attracted by it, and are stuck through the external high-voltage power grid and electrocuted to death.
When people use this kind of mosquito killer, they often hear the popping sound, which is the sound made by instant high-pressure mosquito killing. The setting of high-voltage power grid has the hidden danger of electric shock, especially children, who can't touch and play at close range. Once they accidentally touch the high-voltage power grid when the mosquito killer is running, the consequences are unimaginable;
Not only that, the scattered mosquito bodies shattered by the high-voltage power grid will continue to pollute the environment, and if inhaled by the human body, it will be contagious.
The suction mosquito killer relies on the vortex airflow generated by the fan in the lamp to drag the mosquitoes close to it into the lamp and make them dry and dehydrate to death. Only when the power supply and the built-in fan are running and the mosquito body is locked in the mosquito killer, there is a danger of electric shock and injury. To sum up, inhalation mosquito killer is safer than electric mosquito killer.
The light in the mosquito killer is an ultraviolet ray, but the light frequency is much lower than that of the money detector. "phototaxis is the nature of mosquitoes. But mosquito killers don't just kill mosquitoes.
The light waves emitted by the mosquito killer attract mosquitoes to the trapping ring in the mosquito killer. Once mosquitoes enter the mosquito killer, they can be killed by high-voltage electric shock or inhalation and air drying. "
The light frequency used by mosquito killer is generally between 330-380nm of ultraviolet light wave, because this band of light is the favorite of mosquitoes, and only ultraviolet light wave above several thousand nm will cause harm to human body.
