micro gas transfer device

Abstract

A miniature gas transmission device comprises the components of a gas outlet plate which is provided with a gas outlet pipe, a gas outlet and a plurality of projections, wherein the gas outlet pipe isarranged on the first surface of the gas outlet plate, the gas outlet is arranged in the gas outlet pipe and penetrates through the gas outlet plate for discharging gas, the plurality of projectionsare arranged on the second surface of the gas outlet plate, and at least one ventilating opening which is recessed is defined between two adjacent projections; a resonance plate; a piezoelectric actuator which has a suspension plate that has a first surface and a second surface; an outer frame; at least one bracket which is connected with the suspension plate and the outer frame and is arranged between the suspension plate and the outer frame; a piezoelectric component which adheres to the first surface of the suspension plate; and a cover plate which has a side wall and a base plate, whereinthe side wall projects from the base plate in a manner of surrounding the circumferential edge of the base plate and forms an accommodating space with the base plate.

Description

【Technical field】 [0001] This case is about a miniature gas transmission device, especially a miniature ultra-thin and silent micro gas transmission 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, the fluid delivery included in products such as micro pumps, sprayers, inkjet heads, and industrial printing devices Structure is its key technology, so how to use innovative structure to break through its technical bottleneck 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 structure of these traditional motors and gas valves, it is difficult to reduce the volume of such ...

AI Technical Summary

Problems solved by technology

However, limited by the structure of these traditional motors and gas valves, it is difficult to reduce the volume of such instruments and equipment, so that the volume of the overall device cannot be reduced, that is, it is difficult to achieve the goal of thinning, so it is impossible to install It is not convenient to use on or in conjunction with portable devices, and these traditional motors and gas valves also generate noise when they are actuated, making users anxious, resulting in inconvenient and uncomfortable use

[0004] In addition, the gas inlet and outlet of the known micro-gas transmission device are performed by different components, so it must have many components to achieve the purpose of gas inlet and outlet. However, due to the large number of components required, the assembly process is more complicated.
