The utility model provides an ultrasonic
coupling agent spraying device suitable for special equipment. The utility model provides an ultrasonic
coupling agent spraying device. The ultrasonic
coupling agent spraying device comprises a box provided with a holding part, a
nozzle assembly, a liquid suction
pipe and a limiting switch. A containing groove is formed in the top of the box body, and the
nozzle assembly is arranged in the containing groove and can be switched between the vertical direction and the horizontal direction. A limiting switch is arranged on the containing groove and used for limiting movement of the
nozzle assembly. The top of the liquid suction
pipe is communicated with the nozzle assembly, and the rest part of the liquid suction
pipe is inserted into the box body; when the ultrasonic coupling agent spraying device is used, the ultrasonic coupling agent spraying device can be fixed to the hand through the holding part, the limiting switch is controlled through the
thumb, so that the nozzle assembly is switched from the horizontal state to the vertical state, then the
thumb continues to be operated to control the nozzle assembly, and an ultrasonic coupling agent in the box body flows out of the nozzle assembly; and after the ultrasonic coupling agent is sprayed, the limiting switch is controlled by the
thumb again, so that the nozzle assembly is recovered from the vertical state to the horizontal state.
