LIQUID DISPENSER USING ULTRASONIC ACTUATOR

摘要

PURPOSE: A liquid dispenser using an ultrasonic actuator is provided, which exhibits a uniform dispensing rate and high efficiency even for a highly viscous liquid and is manufactured at low cost. CONSTITUTION: The liquid dispenser using an ultrasonic actuator comprises: an ultrasonic actuator(1) that actuates using power supplied through an electronic circuit(7); a vibration plate(2) attached to the ultrasonic actuator(1) to vibrate together with the same and cut to have a hole having a diameter of 1 to 20 mm, and a bent portion(21) produced by bending the cut portion; and a core(3) that absorbs a liquid stored in a liquid container(5) and having a top surface contacting the bent portion(21). The liquid absorbed into the core(3) is dispensed from a portion contacting the bent portion(21) by vibration of the vibration plate(2).
