[Technical Field]

The present invention relates to the field of mosquito killers and, more particularly, to an airflow type mosquito killer.

【Background technique】

Mosquitoes like to bite people or animals. In order to kill mosquitoes, people not only use mosquito coils, but also use mosquito swatters, electric mosquito swatters and DC mosquito traps. In addition, mosquito nets are used to block mosquitoes. Among them, mosquito coils can pollute the air during use, which is harmful to the human body, especially children, pregnant women and people with respiratory diseases; mosquito swatters or electric mosquito swatters require the user to keep waving with their hands, not only tiring And trouble, in addition, the effect of killing mosquitoes is not good enough; the DC type mosquito trap is equipped with lights, the mosquitoes tend to light, the mosquitoes are attracted by the light, the conductive tubes are arranged around the tubes for emitting lights, and the conductive lines are connected to the direct current When the mosquito enters the DC type mosquito trap, it will contact with the conductive wire and be directly electrocuted by the direct current. The mosquito trap is smokeless and tasteless by the direct current mosquito. The mosquito trap can automatically kill the mosquito after being energized. The mosquito effect is good.

However, since the DC-type mosquito trap directly kills mosquitoes that are close to the conductive wire by direct current, the user is vulnerable to direct current electric shock during use, which is not safe enough, especially for children. I have designed an airflow type mosquito killer, including a casing, a lamp fixed in the casing, a circuit board and a fan, and the casing corresponding to the fan is provided with an air inlet and an air outlet, and the casing is provided with a mosquito storage corresponding to the air outlet.
