The insect trap embodies two primary operations including actuation of ultrasonic waves to excite an attractant and form a mist and formation of an airflow backpressure, thereby ensuring that the attractant is not disturbed by external forces during the course of volatilization, and thus preventing dilution of the attractant. Moreover, intermittent operation of a motor results in substantial savings in power. The insect trap primarily uses a mist excitation device 2 to excite and disperse an insect attractant as attractant particles that suspend in the air and diffuse. After achieving a predetermined diffusion concentration, operation switches over to actuate a backpressure device 5, which pressures insects attracted close to an attracting area into a receiving chamber through a mechanical unidirectional valve. A preparation inducement period and alternating working times realize mechanical ensnaring of insects, and provides power saving features and safety in use. |
