Abstract: An ultrasonic spray coating system includes a piezoelectric transducer, a spray-forming head and a liquid supply applicator. The spray-forming head has an air-entrainment mechanism. The air-entrainment mechanism has an air-stream channel that is formed inside a main body and a bottom body of the spray-forming head for connection with a high-pressure air source, and an air vent formed in a bottom surface of the bottom body and communicates with the air-stream channel. A length of the air vent in a horizontal direction is greater than that of the air-stream channel. The liquid supply applicator has a discharge orifice, and a control component for controlling the size of the discharge orifice.

Abstract: A feeding mold is provided with a charging runner for coating, a feeding runner connected to the charging runner, and a mold base adjacent to the feeding runner. The feeding runner is provided with a splitting manifold communicated with the charging runner, a discharging end face located at the end of feeding runner and apart from an atomizing knife edge of ultrasonic oscillating element by a gap, and a slit channel connected to the splitting manifold and discharging end face. The mold base is connected at a side edge thereof to the bottom of discharging end face, and inclined at a first angle toward the discharging end face. The side edge is located at the lowest position. Accordingly, the backflow of coating on the discharging end face to the mold base from the side edge and formation of trickle are impossible, so as to use coating adequately and avoid pollution.
