PURPOSE: An ultrasonic wave mosquito killing machine is provided to paralyze the nervous system of a mosquito and then kill the mosquito by radiating the ultrasonic wave of 40 KHz at 120 decibels and making the 12th articular joint among thirteen articular joints of the mosquito detect and react the electric signal. CONSTITUTION: An ultrasonic wave mosquito killing machine radiates ultrasonic wave by using a sensor for exclusively using ultrasonic wave, wherein the wave uses a longitudinal wave of ultrasonic waves, that is capable of present in a solid body, liquid, and gaseous body. Two ultrasonic wave sensors are disposed oppositely each other, such that a spiral pulse is doubled than a case using a single sensor. The prior machine using an audible frequency constituted by lowering the sound not to be audible to human being, whereas the present machine uses an amplitude of 120 decibels (comparable with an amplitude, 60 decibels, upon human being speaks) so as to instantly detect the mosquito coming into the band of the amplitude. A main board(7) of the ultrasonic wave mosquito killing machine(5) is constituted to have a frequency generator(5) and an electronic sensor(6) which are mounted in a lower case(4) and a battery casing(8) formed therein, in which batteries are inserted. A turn on/off switch(10) is mounted on the main board(7) to be protruded from the lower case(4) by attaching an upper case(12) and a lower case(4) each other.
