Problems solved by technology

However, limited by the volume limitations of these traditional motors and gas valves, it is difficult to reduce the overall device volume of such instruments and equipment, that is, it is difficult to achieve the goal of thinning, and it is impossible to make it portable.
In addition, these traditional motors and gas valves will also generate noise when they are in operation, resulting in inconvenience and discomfort in use

Abstract

A piezoelectric actuator is suitable for a miniature fluid control device. The piezoelectric actuator comprises a suspension board, an outer frame, a plurality of brackets and a piezoelectric ceramicboard. The suspension board is square-shaped and has a first surface and a corresponding second surface. The second surface is provided with a projection. The outer frame is arranged outside the suspension board in a surrounding manner and has a first surface and a corresponding second surface. Furthermore the second surface of the outer frame and the second surface of the suspension board are coplanar except for the outer area of the projection. The bracket is connected between the suspension board and the outer frame and has a length of 1.11mm to 1.21mm and a width of 0.2mm to 0.6mm. The piezoelectric ceramic board has an edge length which does not exceed that of the suspension board, and furthermore adheres to the first surface of the suspension board.

Description

technical field [0001] The invention relates to a piezoelectric actuator, in particular to a piezoelectric actuator suitable for a miniature ultra-thin and quiet micro fluid control device. Background technique [0002] At present, in various fields, whether it is medicine, computer technology, printing, energy and other industries, products are developing towards refinement and miniaturization. Among them, micro pumps, sprayers, inkjet heads, industrial printing devices and other products contain fluid delivery structures. Its key technology, therefore, how to break through its technical bottleneck through innovative structure is an important content of development. [0003] For example, in the pharmaceutical industry, many instruments or equipment that need to be driven by pneumatic power usually use traditional motors and pneumatic valves to achieve the purpose of gas delivery. However, limited by the volume limitations of such traditional motors and gas valves, it is di...
