Fluid transportation actuator

Abstract

A fluid transportation actuator is disclosed and includes a silencing jet orifice plate, a chamber frame, an actuator, an insulation frame and a conductive frame. The silencing jet orifice plate includes a silencing plate, a suspension plate and a central aperture. The suspension plate is permitted to undergo a bending vibration. The central aperture is formed on a center of the suspension plate. The silencing plate is disposed and fixed in the central aperture disposed at the center of the suspension plate. The chamber frame is stacked on the suspension plate. The actuator is stacked on the chamber frame. The actuator generates the bending vibration in a reciprocating manner as a voltage is applied thereto. The actuator includes a piezoelectric-thin-plate pin. The insulation frame is stacked on the actuator. The conductive frame is stacked on the insulation frame and includes a conductive-frame pin.

FIELD OF THE INVENTION[0001]The present disclosure relates to a fluid transportation actuator, and more particularly to a fluid transportation actuator assembled and combined with different metal materials.BACKGROUND OF THE INVENTION[0002]In the prior art, fluid transportation actuators are mainly constructed by stacking conventional mechanical components, and each mechanical component is miniaturized or thinned to achieve the goal of miniaturization and thinning of the overall device. However, while the conventional mechanical components are miniaturized, it is not easy to control the dimensional accuracy, and the assembly accuracy is also difficult to control. It results in different product yields and even unstable fluid flow rates. In addition, while the mechanical components are miniaturized, the single-material fluid transportation actuator has the problem of insufficient structural toughness during being driven and easy to result in the problems of interference and unrecogniz...

AI Technical Summary

Benefits of technology

The present patent describes a fluid transportation actuator that includes a silencing jet orifice plate, a chamber frame, an actuator, insulation frame and a conductive frame. The actuator generates bending vibrations to achieve fluid transportation when a voltage is applied to it. The silencing jet orifice plate is driven in resonance by the actuator to vibrate and displace the suspension plate, which causes a displacement of the fluid in the chamber. The technical effects of this actuator include improved fluid transportation with reduced noise and vibrations.

Problems solved by technology

However, while the conventional mechanical components are miniaturized, it is not easy to control the dimensional accuracy, and the assembly accuracy is also difficult to control.

It results in different product yields and even unstable fluid flow rates.

In addition, while the mechanical components are miniaturized, the single-material fluid transportation actuator has the problem of insufficient structural toughness during being driven and easy to result in the problems of interference and unrecognizable of the driving point.

Furthermore, in the conventional fluid transportation actuator, the output fluid cannot be converged effectively or the element size is too small results in insufficient fluid propulsion force.

It leads to the problem of insufficient amount of fluid transportation.
