Abstract: An air-flowing type mosquito killing device comprises a housing, a circuit board, a lamp, and a fan fixed in the housing by a screw. The housing corresponding to an air outlet of the fan is configured with a mosquito opening. The present disclosure use the fan fixed in the housing by the screw, which makes the fan firmly fixed in the housing because of the firm fixing of the screw. The screw is convenient to be installable or disassemble, which saves installation time, and is convenient to inspect and maintain when the failure occurs. The mosquitoes are attracted by the light, airflow generated by the fan draws the mosquitoes to the housing, and the mosquitoes are blown the mosquito opening. The fan constantly rotates, which dries the air and dehydrates the mosquitoes, thus killing the mosquito and keeping people far away from mosquito distractions.
