The present utility model is related to a suction-type device for capturing insects. It comprises a shell, a fan unit, a motive power unit, an electric power unit, a switch and a net section. The shell comprises an opening. The switch is electrically connected with the electric power unit for controlling the on/off state of a circuit of the electric power unit. The electric power unit generates electric energy and transmits the electric energy to the motive power unit. The motive power unit generates kinetic energy and transmits the kinetic energy to the fan unit. The fan unit is located inside the shell and generates airflow. The airflow penetrates through the opening and draws the insects toward the inside of the shell. The net section is located on a side of opposite to the opening to capture the insects which are drawn inward by the airflow.本創作係關於一種吸入式蚊蟲捕捉裝置，包含一殼體、一扇葉單元、一動力單元、一電力單元、一開關及一網部。該殼體具有一開口。該開關電性連接至該電力單元，用以控制該電力單元之電路的導通態樣。該電力單元用以產生一電能，並且將該電能傳遞至該動力單元。該動力單元用以產生一動能，並且將該動能傳遞至該扇葉單元。該扇葉單元係設於該殼體的內部，用以產生一氣流。其中該氣流能從該殼體的外部穿透該開口，並且將該開口外的蚊蟲吸入該殼體內。該網部係設於該開口的相反側，用以攔阻被吸入該殼體內的該蚊蟲。
