Description

本考案は、微小液滴生成装置に関し、特に、微小液滴生成効果を向上させた微小液滴生成装置に関する。 The present invention relates to a microdroplet generation device, and more particularly to a microdroplet generation device with an improved microdroplet generation effect.

現在市場で最も広く使用されている霧化装置は、通常圧電材料からなる振動素子、及びノズルの二部材を具え、振動素子を液体を収容するチャンバ内に設置し、またはノズルと連結して、圧電材料の導電時に発生する高速往復振動を利用して、液体が前述のノズルを通過するようにするか、あるいはノズルを駆動して振動を発生させて、液体が高周波振動を受けてノズルから噴出するようにして、液体がノズルの微小な噴出孔から微細な液体顆粒となって噴出するようにして液体霧化を行っている。 Currently, the most widely used atomizing apparatus on the market comprises two members, a vibration element and a nozzle, usually made of a piezoelectric material, and the vibration element is installed in a chamber containing liquid or connected to a nozzle. Utilizing the high-speed reciprocating vibration generated when the piezoelectric material conducts, the liquid passes through the nozzle described above, or the nozzle is driven to generate vibration, and the liquid is subjected to high-frequency vibration and ejected from the nozzle. Thus, the liquid atomization is performed so that the liquid is ejected as fine liquid granules from the minute ejection holes of the nozzle.

図１に示すように、公知技術の微小液滴霧生成装置の構造断面図では、微小液滴霧生成装置１はノズル１１及び振動素子１２を具え、ノズル１１に微細噴出孔１１１を密に形成し、振動素子１２とノズル１１は一固定間隙１２１を保持し、振動素子１２の駆動によって往復振動して、流体を圧迫し、ノズル１１の噴出孔１１１から噴出するようにして、微小霧滴を形成する。
しかし、この種の設計ではノズルと振動素子との間隙を厳密に制御しなければ微細霧滴を噴出する機能を達成できないため、相互の対応が製造上非常に難しい。
特開２００３−３８６４６号公報 As shown in FIG. 1, in the structure cross-sectional view of a known micro droplet mist generation device, the micro droplet mist generation device 1 includes a nozzle 11 and a vibration element 12, and fine ejection holes 111 are densely formed in the nozzle 11. The vibrating element 12 and the nozzle 11 hold a fixed gap 121, reciprocally vibrate by driving the vibrating element 12, press the fluid, and eject the fine mist droplets from the ejection hole 111 of the nozzle 11. Form.
However, in this type of design, the function of ejecting fine mist droplets cannot be achieved unless the gap between the nozzle and the vibration element is strictly controlled.
