When the ozone concentration is 0.02ppm, people with a sensitive sense of smell can detect it, which is called the sensory threshold. When the concentration is 0.15ppm, it is the olfactory threshold, which can be smelled by most people, and it is also a health standard point. When the concentration reaches 1-10ppm, it is called the irritation range. In fact, the safe use of ozone can completely ensure that human health is not endangered.

The solar mosquito killer lamp is a product approved by the state as a utility model patent. This product uses solar energy (amorphous silicon) production technology and new solar cell technology to convert solar energy into electrical energy storage, and uses solar energy to supply power to the mosquito lamp tube, which causes the temptation of mosquitoes and electrocutes the mosquitoes to death. Its larger power comes from solar thermal power, which has made great progress in [1] and…
