1376455 九、發明說明：1376455 IX. Description of invention:
V 【發明所屬之技術領域】 ’ 本案係關於一種流體輸送裝置，尤指一種適用於微幫 浦結構之流體輸送裝置。 < 【先前技術】 目前於各領域中無論是醫藥、電腦科技、列印、能源 等工業，產品均朝精緻化及微小化方向發展，其中微幫 * 浦、喷霧器、喷墨頭、工業列印裝置等產品所包含之流體 輸送結構為其關鍵技術，是以，如何藉創新結構突破其技 ' 術瓶頸，為發展之重要内容。 ^ 請參閱第一圖（a)，其係為習知微幫浦結構於未作動時 之結構示意圖，習知微幫浦結構10係包含入口通道13、 微致動器15、傳動塊14、隔層膜12、壓縮室111、基板 11以及出口通道16,其中基板11與隔層膜12間係定義形 φ 成一壓縮室111，主要用來儲存液體，將因隔層膜12之形 變影響而使得壓縮室111之體積受到改變。 當一電壓作用在微致動器15的上下兩極時，會產生 一電場，使得微致動器15在此電場之作用下產生彎曲而 向隔層膜12及壓縮室111方向移動，由於微致動器15係 設置於傳動塊14上，因此傳動塊14能將微致動器15所 產生的推力傳遞至隔層膜12,使得隔層膜12也跟著被擠 壓變形，即如第一圖（b)所示，液體即可依圖中箭號X之方 向流動，使由入口通道13流入後儲存於壓縮室111内的液 6 1376455 v 體受擠壓，而經由出口通道16流向其他預先設定之空間， 以達到供給流體的目的。 • 請再參閱第二圖，其係為第一圖⑷所示之微幫浦結構 之俯視圖，如圖所示，當微幫浦結構10作動時流體之輸 送方向係如圖中標號Y之箭頭方向所示，入口擴流器17 係為兩端開口大小不同之錐狀結構，開口較大之一端係與 入口流道191相連接，而以開口較小之一端與微壓縮室111 I 連接，同時，連接壓縮室111及出口流道192之擴流器18 係與入口擴流器17同向設置，其係以開口較大的一端連 接於壓縮室111，而以開口較小的一端與出口流道192相 連接，由於連接於壓縮室111兩端之入口擴流器17及出口 擴流器18係為同方向設置，故可利用擴流器兩方向流阻 不同之特性，及壓縮室111體積之漲縮使流體產生單方向 之淨流率，以使流體可自入口流道191經由入口擴流器17 流入壓縮室111内，再由出口擴流器18經出口流道192 > 流出。 此種無實體閥門之微幫浦結構10容易產生流體大量 回流的狀況，所以爲促使流率增加，壓縮室111需要有較 大的壓縮比，以產生足夠的腔壓，故需要耗費較高的成本 在致動器15上。 因此，如何發展一種可改善上述習知技術缺失之流體 輸送裝置，實為目前迫切需要解決之問題。 7 1376455 【發明内容】 本案之主要目的在於提供一種流體輸送裝置，主要由 閥體座、閥體薄膜、閥體蓋體、振動薄膜及致動器堆疊而 成，其係藉由致動器作動時帶動振動薄膜產生形變，使介 於振動薄膜及閥體蓋體間之壓力腔室的體積改變，以產生 正負之壓力差，同時，由於閥體薄膜上之閥門結構其開合 反應迅速，使得壓力腔室於漲縮的瞬間可產生較大之流體 吸力與推力，故可使流體達到高效率之傳輸，並可有效阻 擋流體之逆流，俾解決習知技術之微幫浦結構於流體的傳 送過程中易產生流體回流之現象。 為達上述目的，本案之較廣義實施態樣為提供一種 流體輸送裝置，用以傳送流體，其係包含：閥體座，其係 具有出口通道及入口通道；閥體蓋體，其係設置於閥體座 上；閥體薄膜，其厚度係實質上相同，且設置於閥體座及 閥體蓋體之間，並具有複數個鏤空閥開關，包含第一閥開 關及第二閥開關；複數個暫存室，於閥體薄膜與閥體蓋體 之間形成第一暫存室，以及於閥體薄膜與該閥體座之間形 成第二暫存室；振動薄膜，其週邊係固設於閥體蓋體，於 未作動狀態時，振動薄膜係與閥體蓋體分離，以定義形成 壓力腔室；以及致動器，其係與振動薄膜連接；其中，當 致動器受電壓驅動而造成彎曲變形時，與致動器連接之振 動薄膜將連動而致使壓力腔室體積改變，進而產生壓力差 推動該流體，由該入口通道流經第一閥開關、第一暫存 室、壓力腔室、第二暫存室、第二闊開關後，從出口通道 8 1376455 流出。 【實施方式】 體現本案特徵與優點的一些典型實施例將在後段的 說明中詳細敘述。應理解的是本案能夠在不同的態樣上具 有各種的變化，其皆不脫離本案的範圍，且其中的說明及 圖示在本質上係當作說明之用，而非用以限制本案。 請參閱第三圖，其係為本案第一較佳實施例之流體輸 送裝置之結構示意圖，如圖所示，本案之流體輸送裝置20 可適用於醫藥生技、電腦科技、列印或是能源等工業，且 可輸送氣體或是液體，但不以此為限，流體輸送裝置20 主要係由閥體座21、閥體蓋體22、閥體薄膜23、複數個 暫存室、致動裝置24及蓋體25所組成，其中閥體座21、 閥體蓋體22、閥體薄膜23係形成一流體閥座201，且在 閥體蓋體22及致動裝置24之間形成一壓力腔室226，主 要用來儲存流體。 該流體輸送裝置20之組裝方式係將閥體薄膜23設置 於閥體座21及閥體蓋體22之間，並使閥體薄膜23與閥 體座21及閥體蓋體22相對應設置，且在閥體薄膜23與 閥體蓋體22之間形成一第一暫存室，而在閥體薄膜23與 閥體座21之間形成一第二暫存室，並且於閥體蓋體22上 之相對應位置更設置有致動裝置24，致動裝置24係由一 振動薄膜241以及一致動器242組裝而成，用以驅動流體 輸送裝置20之作動，最後，再將蓋體25設置於致動裝置 9 1376455 r 24之上方，故其係依序將閥體座21、閥體薄膜23、閥體 * 蓋體22、致動裝置24及蓋體25相對應堆疊設置，以完成 ' 流體輸送裝置20之組裝。 其中，閥體座21及閥體蓋體22係為本案流體輸送裝 . 置20中導引流體進出之主要結構，請參閱第四圖並配合 . 第三圖，其中第四圖係為第三圖所示之閥體座的侧面結構 示意圖，如圖所示，閥體座21係具有一個入口流道211 I 以及一個出口流道212，流體係可由外界輸入，經由入口 流道211傳送至閥體座21上表面210之一開口 213,並且， 於本實施例中，閥體薄膜23及閥體座21之間所形成的第 二暫存室即為圖中所示之出口暫存腔215，但不以此為 限，其係由閥體座21之上表面210於與出口流道212相 對應之位置產生部分凹陷而形成，並與出口流道212相連 通，該出口暫存腔215係用以暫時儲存流體，並使該流體 由出口暫存腔215經由一開口 214而輸送至出口通道 • 212，再流出閥體座21之外。以及，在閥體座21上更具 有複數個凹槽結構，用以供一密封環26(如第七圖（a)所示） 設置於其上，於本實施例中，閥體座21係具有環繞開口 213週邊之凹槽216、218，及環繞於出口暫存腔215週 邊之凹槽217。 請參閱第五圖（a)並配合第三圖，其中第五圖（a)係為第 三圖所示之閥體蓋體之背面結構示意圖，如圖所示，閥體 蓋座22係具有一上表面220及一下表面228,以及在閥體 蓋座22上亦具有貫穿上表面220至下表面228之入口閥 鬥通道221及出口閥門通道222，且該入口閥門通道221 係設置於與閥體座21之開口 213相對應么位置’而出口 闕門通道222則設置於與閥體座21之出口暫存腔215内 之開口 214相對應之位置，並且，於本實施例中’閥體薄 勝23及闕體蓋體22之間所形成之第一暫#室即為圖中所 系之入口暫存腔223，且不以此為限，其係由閥體蓋體22 之下表面228於與入口閥門通道221相對應之位置產生部 份凹陷而形成，且其係連通於入口閥門通道221 ° 請參閱第五圖（b)，其係為第五圖⑷之别面結構示意 圖，如圖所示，閥體蓋體22之上表面22〇係部份凹陷’ 以形成一壓力腔室226，其係與致動裝置24之致動器242 相對應設置，壓力腔室226係經由入口閥門通道221連通 於入口暫存腔223，並同時與出口閥門通道222相連通， 因此，當致動器242受電壓致動使致動裝置24上凸變形’ 造成壓力腔室226之體積膨脹而產生負壓差，可使流體經 入口閥門通道221流至壓力腔室226内，其後，當施加於 致動器242的電場方向改變後，致動器242將使致動裝置 24下凹變形壓力腔室226收縮而體積減小，使壓力腔室 226與外界產生正壓力差，促使流體由出口閥門通道222 流出壓力腔室226之外，於此同時，同樣有部分流體會流 入入口閥門通道221及入口暫存室223内，然而由於此時 的入口閥門結構231(如第六圖（c)所示）係為使受壓而關閉 的狀態，故該流體不會通過入口閥片231而產生倒流的現 象，至於暫時儲存於入口暫存腔223内之流體，則於致動 1376455 ¥ 器242再受電壓致動，重複使致動裝置24再上凸變形而 增加壓力腔室226體積時，再由入口暫存腔223經至入口 ' 閥門通道221而流入壓力腔室226内，以進行流體的輸送。 另外，閥體蓋體22上同樣具有複數個凹槽結構，以 . 本實施例為例，在閥體蓋座22之上表面220係具有環繞 、 壓力腔室226而設置之凹槽227，而在下表面228上則具 有環繞設置於入口暫存腔223之凹槽224、環繞設置於出 ^ 口閥門通道222之凹槽225以及凹槽229，同樣地，上述 凹槽結構係用以供一密封環27(如第七圖（a)所示）設置於 其中。 請參閱第六圖（a)並配合第三圖，其中第六圖（a)係為第 三圖所示之閥體薄膜之結構示意圖，如圖所示，閥體薄膜 23主要係以傳統加工、或黃光蝕刻、或雷射加工、或電鑄 加工、或放電加工等方式製出，且為一厚度實質上相同之 薄片結構，其上係具有複數個鏤空閥開關，包含第一閥開 φ 關以及第二閥開關，於本實施例中，第一閥開關係為入口 閥門結構231，而第二閥開關係為出口閥門結構232，其 中，入口閥門結構231係具有入口閥片2313以及複數個 環繞入口閥片2313週邊而設置之鏤空孔洞2312，另外， 在孔洞2312之間更具有與入口閥片2313相連接之延伸部 2311，當閥體薄膜23承受一自壓力腔室226傳遞而來向 下之應力時，如第七圖⑷所示，入口閥門結構231係整個 向下平貼於閥體座21之上，此時入口閥片2313會緊靠凹 槽216上密封環26突出部分，而密封住閥體座21上之開 12 1376455 、 口 213，且其外圍的鏤空孔洞2312及延伸部2311則順勢 浮貼於閥體座21之上，故因此入口閥門結構231之關閉 作用，使流體無法流出。 而當閥體薄膜23受到壓力腔室226體積增加而產生 . 之吸力作用下，由於設置於閥體座21之凹槽216内的密 . 封環26已提供入口閥門結構231 —預力（Preforce)，因而 入口閥片2313可藉由延伸部2311的支撐而產生更大之預 I 蓋緊效果，以防止逆流，當因壓力腔室226之負壓而使入 口閥門結構231往上產生位移（如第六圖（b)所示），此時， 流體則可經由鏤空之孔洞2312由閥體座21流至閥體蓋體 22之入口暫存腔223，並經由入口暫存腔223及入口閥門 通道221傳送至壓力腔室226内，如此一來，入口閥門結 構231即可因應壓力腔室226產生之正負壓力差而迅速的 開啟或關閉，以控制流體之進出，並使流體不會回流至閥 體座21上。 • 同樣地，位於同一閥體薄膜23上的另一閥門結構則 為出口閥門結構232，其中之出口閥片2323、延伸部2321 以及孔洞2322之作動方式均與入口閥門結構231相同， 因而不再贅述，惟出口閥門結構232週邊之密封環26設 置方向係與入口閥門結構231之密封環27反向設置，如 第六圖（c)所示，因而當壓力腔室226壓縮而產生一推力 時，設置於閥體蓋體22之凹槽225内的密封環27將提供 出口閥門結構232 —預力（Preforce)，使得出口閥片2323 可藉由延伸部2321之支撐而產生更大之預蓋緊效果，以 13 1376455 防止逆流，當因壓力腔室226之正壓而使出口閥門結構232 往下產生位移，此時，流體則可經由鏤空之孔洞2322由 壓力腔室226經閥體蓋體22而流至閥體座21之出口暫存 腔215内，並可經由開口 214及出口流道212排出，如此 一來，則可經由出口閥門結構232開啟之機制，將流體自 壓力腔室226内洩出，以達到流體輸送之功能。 請參閱第七圖（a)，其係為本案較佳實施例之流體輸送 裝置之未作動狀態示意圖，於本實施例中，所有的凹槽結 構216、217、218分別設置密封環26，而凹槽224、225、 229内亦分別設置密封環27，其材質係為可耐化性佳之橡 膠材料，且不以此為限，其中，設置於閥體座21上環繞 開口 213之凹槽216内的密封環可為一圓環結構，其厚度 係大於凹槽216深度，使得設置於凹槽216内之密封環26 係部分凸出於閥體座21之上表面210構成一微凸結構， 因而使得貼合設置於閥體座21上之閥體薄膜23之入口閥 門結構231之入口閥片2313因密封環26之微凸結構而形 成一向上隆起，而闊體薄膜23之其餘部分係與閥體蓋體 22相抵頂，如此微凸結構對入口閥門231頂推而產生一預 力（Preforce)作用，有助於產生更大之預蓋緊效果，以防止 逆流，且由於密封環26向上隆起之微凸結構係位於閥體 薄膜23之入口閥門結構231處，故使入口閥門結構231 在未作動時使入口閥片2313與閥體座21之上表面210之 間具有一間隙，同樣地，當密封環27設置於環繞出口閥 門通道222之凹槽225内時，由於其密封環27係設置於 1376455 閥體蓋體22之下表面228，因而該密封環27係使閥體薄 膜23之出口閥門結構向下凸出而形成一向下隆起於閥體 ' 蓋體22之微凸結構，此微凸結構僅其方向與形成於入口 閥門結構231之微凸結構係為反向設置，然而其功能均與 . 前述相同，因而不再贅述。至於其餘分別設置於凹槽結構 . 217、218及224、229以及227内之密封環26、27及28， 主要用來分別使閥體座21與閥體薄膜23、閥體薄膜23與 閥體蓋體22以及閥體蓋體22與致動裝置24之間緊密貼 合時，防止流體外洩。 當然，上述之微凸結構除了使用凹槽及密封環來搭配 形成外，於一些實施例中，閥體座21及閥體蓋體22之微 凸結構亦可採用半導體製程，例如：黃光蝕刻或鍍膜或電 鑄技術，直接在閥體座21及閥體蓋體22上形成。 請同時參閱第七圖（a)、（b)、（c)，如圖所示，當蓋體 25、致動裝置24、閥體蓋體22、閥體薄膜23、密封環26 φ 以及閥體座21彼此對應組裝設置後，閥體座21上之開口 213係與閥體薄膜23上之入口閥門結構231以及閥體蓋體 22上之入口閥門通道221相對應，且閥體座21上之開口 214則與閥體薄膜23上之出口閥片232以及閥體蓋體22 上之出口閥門通道222相對應，並且，由於密封環26設 置於凹槽216内，使得閥體薄膜23之入口闊門結構231 微凸起於閥體座21之上，並藉由位於凹槽216内之密封 環26頂觸閥體薄膜23而產生一預力（(Preforce)作用，使 得入口閥門結構231在未作動時則與閥體座21之上表面 15 1376455 210形成一間隙，同樣地，出口閥門結構232亦藉由將密 封環27設至於凹槽225中的相同方式與閥體蓋體22之下 表面228形成一間隙。 當以一電壓驅動致動器242時，致動裝置24產生 彎曲變形，如第七圖（b)所示，致動裝置24係朝箭號a所 指之方向向上彎曲變形，使得壓力腔室226之體積增加， 因而產生一吸力，使閥體薄膜23之入口閥門結構231、出 口閥門結構232承受一向上之拉力，並使已具有一預力 (Preforce)之入口閥門結構231之入口閥片2313迅速開啟 (如第六圖（b)所示），使液體可大量地自閥體座21上之入口 通道211被吸取進來，並流經閥體座21上之開口 213、閥 體薄膜23上之入口閥門結構231之孔洞2312、闊體蓋體 22上之入口暫存腔223、入口閥片通道221而流入壓力腔 室226之内，此時，由於閥體薄膜23之入口閥門結構231、 出口閥門結構232承受該向上拉力，故位於另一端之出口 閥門結構232係因該向上拉力使得位於閥體薄膜23上之 出口閥片2323密封住出口閥門通道222,而使得出口閥門 結構232關閉，因而流體逆流。 當致動裝置24因電場方向改變而如第七圖⑷所示之 箭號b向下彎曲變形時，則會壓縮壓力腔室226之體積， 使得壓力腔室226對内部之流體產生一推力，並使閥體薄 膜23之入口閥門結構231、出口閥門結構232承受一向下 推力，此時，設置於凹槽225内之密封環27上出口閥門 結構232的出口閥片2323其可迅速開啟（如第六圖（c)所 16 1376455 示），並使液體瞬間大量宣洩，由壓力腔室226經由閥體蓋 % ' 體22上之出口闕門通道222、閥體薄膜23上之出口閥門 結構232之孔洞2322、閥體座21上之出口暫存腔215、 開口 214及出口通道212而流出流體輸送裝置20之外， 因而完成流體之傳輸過程，同樣地，此時由於入口閥門結 構231係承受該向下之推力，因而使得入口閥片2313密 封住開口 213 ’因而關閉入口閥門結構231 ’使得流體不 逆流，並且’藉由入口閥門結構231及出口閥門結構232 I 配合設置於閥體座21及閥體蓋體22上之凹槽216、225 内的密封環26、27之設計，可使流體於傳送過程中不會 產生回流的情形，達到高效率之傳輸。 另外，於本實施例中，閥體座21以及閥體蓋體22之 材質係可採用熱塑性塑膠材料，例如聚碳酸酯樹酯 (Polycarbonate PC)、聚諷（Polysulfone，PSF)、ABS 樹脂 (Acrylonitrile Butadiene Styrene)、縱性低密度聚乙稀 φ (LLDPE)、低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)、 聚丙稀（PP)、聚苯硫醚（Polyphenylene Sulfide，PPS)、對位 性聚苯乙烯（SPS)、聚苯醚（PPO)、聚縮醛 (Polyacetal，POM)、聚對苯二曱酸二丁酯（PBT)、聚偏氟乙 烯(PVDF)、乙烯四氟乙烯共聚物（ETFE)、環狀烯烴聚合物 (COC)等熱塑性塑膠材料，但不以此為限，且於本實施例 中，壓力腔室226之深度係介於100//m至300μ m之間， 直徑介於10~30mm之間，且不以此為限。 % 於本實施例中，該閥體薄膜23與閥體座21及閥體蓋 17 1376455 體22之間的間隙距離可為10以111至79〇ym，且最佳者為 180 // m至300 " m，且於一些實施例中，該致動裝置24 之振動薄膜241與閥體蓋體22間的分隔距離，即間隙， 可為10/z m至790/z m，較佳者為1〇〇以m至3〇〇以m。 而閥體薄膜23係可以傳統加工或黃光餘刻或雷射加 工或電鑄加工或放電加工等方式製出，其材質可為任何耐 化性佳之有機高分子材料或金屬，當閥體薄膜23採用該 高分子材料，其彈性係數為2~ 20 Gpa，例如聚亞酿胺 (Polyimide，PI)，其彈性係數，即楊氏係數（e值）可為 lOGPa，當閥體薄膜23採用金屬材料時，例如鋁、鋁合金、 鎳、鎳合金、鋼、銅合金或不鐵鋼等金屬材料，其揚氏係 數係為2~240GPa’若該金屬材料為鋁金屬，其彈性係數 為70GPa，或是鎳金屬，其彈性係數為210GPa，或是不錄 鋼金屬’其彈性係數為240GPa等，且不以此為限。至於 閥體薄膜23之厚度可介於i〇#m至50"m，最佳者為21> 以 m 至 40 /z m。 以下分別就閥體薄膜23使用不同材質時所製成之方 法提出說明。 當閥體薄膜23之材質係為聚亞醯胺（Polyimide, PI) 時，其製造方法主要係利用反應離子氣體乾蝕刻（reactive ion etching，RIE)之方法’以感光性光阻塗佈於閥門結構之 上’並曝光顯影出閥門結構圖案後，再以進行银刻，由於 有光阻覆蓋處會保護聚亞醯胺（Polyimide，PI)片不被蝕 刻，因而可蝕刻出閥體薄膜23上之閥門結構。 18 1376455 若閥體薄膜23之材質為不銹鋼金屬，則可以黃光蝕 刻、雷射加工及機械加工等製出閥門結構，其中黃光蝕刻 的方式得到在不銹鋼片上的閥門結構之光阻圖案，再浸泡 於FeC13加HC1溶液中進行濕蝕刻，與前述方法類似，有 光阻覆蓋處會保護不銹鋼片不被蝕刻，因而可蝕刻出閥體 薄膜23上之閥門結構。 以及，若是閥體薄膜23之材質係為金屬鎳，則係利 用電鑄成形的方法，同樣利用黃光蝕刻方法，得到在不銹 鋼基板上之閥門結構的光阻圖案，然後進行鎳電鑄，有光 阻覆蓋處不會電鑄，當電鑄之鎳金屬達一定厚度後，將其 從不銹鋼基板上脫離，則可得到具閥門結構231、232之 閥體薄膜23。 另外，除了上述之製造方法之外，應用於閥體薄膜23 之所有材質均可用精密衝孔之加工方法，或是應用傳統機 械加工方式、雷射加工或電鑄加工或放電加工等方式製作 出其上之閥片結構，但不以此為限。 而，致動裝置24内之致動器242係為一壓電板，可 採用高壓電係數之锆鈦酸鉛（PZT)系列的壓電粉末製造而 成，其中致動器242的厚度可介於100// m至500y m之 間，較佳厚度為150 // m至250 /z m，楊氏係數係為100至 150GPa，且不以此為限。 而貼附致動器242之振動薄膜241之厚度為10/zm至 300# m，較佳厚度為100μ m至250// m，其材質可為一 單層金屬所構成，例如不錄鋼金屬，其楊氏係數係為 19 1376455 240Gpa，厚度係介於140// m至160// m，例如銅，其楊氏 係數係為lOOGpa，厚度係介於190/zm至210//m，且不 以此為限，或其材質可為金屬材料上貼附一層耐生化高分 子薄板以構成之雙層結構，。 於一些實施例中，爲了因應大流量流體傳輸的需求， 可於致動裝置24之致動器242上施予操作頻率為 10-50HZ，並配合以下條件： 致動器242之厚度約為100/zm至500//m之剛性特 性，較佳厚度為150 // m至250 /z m，楊氏係數約為 100-150Gpa。 以及振動薄膜241之厚度為10// m至300/z m之間， 較佳厚度為100# m至250/z m，楊氏係數為60-300GPa， 其材質可為一單層金屬所構成，例如不錄鋼金屬，其揚氏 係數係為240Gpa，厚度係介於140 /z m至160 #

device suitable for a micro-push structure. < 【Prior Art】 At present, in various fields, such as medicine, computer technology, printing, energy and other industries, the products are developing in the direction of refinement and miniaturization, among which micro-purifiers, sprayers, inkjet heads, The fluid transport structure contained in products such as industrial printing devices is its key technology. It is how to break through its technical bottlenecks with innovative structures and is an important part of development. ^ Please refer to the first figure (a), which is a schematic diagram of the conventional micro-pull structure when it is not actuated. The conventional micro-push structure 10 series includes an inlet channel 13, a microactuator 15, a transmission block 14, The interlayer film 12, the compression chamber 111, the substrate 11 and the outlet channel 16, wherein the substrate 11 and the interlayer film 12 define a shape φ into a compression chamber 111, which is mainly used for storing liquid, which will be affected by the deformation of the interlayer film 12. The volume of the compression chamber 111 is changed. When a voltage is applied to the upper and lower poles of the microactuator 15, an electric field is generated, causing the microactuator 15 to bend under the action of the electric field to move toward the interlayer film 12 and the compression chamber 111, due to the slight The actuator 15 is disposed on the transmission block 14, so that the transmission block 14 can transmit the thrust generated by the microactuator 15 to the interlayer film 12, so that the interlayer film 12 is also pressed and deformed, that is, as shown in the first figure. (b), the liquid can flow in the direction of the arrow X in the figure, so that the liquid 6 1376455 v stored in the compression chamber 111 after being flowed in through the inlet passage 13 is squeezed, and flows through the outlet passage 16 to other advances. Set the space to achieve the purpose of supplying fluid. • Please refer to the second figure, which is a top view of the micro-push structure shown in the first figure (4). As shown in the figure, when the micro-push structure 10 is actuated, the direction of fluid transport is indicated by the arrow Y in the figure. As shown in the direction, the inlet diffuser 17 is a tapered structure having different opening sizes at both ends, and one of the larger ends is connected to the inlet flow passage 191, and one end of the smaller opening is connected to the micro compression chamber 111 I. At the same time, the diffuser 18 connecting the compression chamber 111 and the outlet flow passage 192 is disposed in the same direction as the inlet diffuser 17, and is connected to the compression chamber 111 with a larger opening, and has a smaller opening and an outlet. The flow passages 192 are connected to each other. Since the inlet diffuser 17 and the outlet diffuser 18 connected to both ends of the compression chamber 111 are disposed in the same direction, the flow resistance of the diffuser can be utilized in different directions, and the compression chamber 111 can be utilized. The volumetric expansion causes the fluid to produce a unidirectional net flow rate such that fluid can flow from the inlet flow passage 191 into the compression chamber 111 via the inlet diffuser 17, and then exit the outlet flow passage 192 > . Such a micro-pump structure 10 without a physical valve is prone to a large amount of fluid backflow. Therefore, in order to increase the flow rate, the compression chamber 111 needs to have a large compression ratio to generate sufficient cavity pressure, so that it is expensive. The cost is on the actuator 15. Therefore, how to develop a fluid delivery device that can improve the above-mentioned conventional techniques is an urgent problem to be solved. 7 1376455 SUMMARY OF THE INVENTION The main object of the present invention is to provide a fluid delivery device which is mainly composed of a valve body seat, a valve body film, a valve body cover body, a vibration film and an actuator, which are actuated by an actuator.

As shown in the figure, the valve body cover 22 has An upper surface 220 and a lower surface 228, and an inlet valve passage 221 and an outlet valve passage 222 extending through the upper surface 220 to the lower surface 228 on the valve body cover 22, and the inlet valve passage 221 is disposed on the valve The opening 213 of the body seat 21 corresponds to the position 'and the outlet door channel 222 is disposed at a position corresponding to the opening 214 in the outlet temporary chamber 215 of the valve body seat 21, and in the present embodiment, the valve body The first temporary chamber formed between the thin win 23 and the body cover 22 is the inlet temporary storage chamber 223, and is not limited thereto, and is the lower surface of the valve body cover 22 228 is partially recessed at a position corresponding to the inlet valve passage 221, and is connected to the inlet valve passage 221 °. See FIG. 5(b), which is a schematic view of the other side of the fifth diagram (4). As shown, the upper surface 22 of the valve body cover 22 is partially recessed to form a pressure chamber 2 26, which is disposed corresponding to the actuator 242 of the actuating device 24, the pressure chamber 226 is communicated with the inlet temporary chamber 223 via the inlet valve passage 221, and simultaneously communicates with the outlet valve passage 222, thus The actuator 242 is actuated by voltage to cause the actuator device 24 to be convexly deformed to cause the volume of the pressure chamber 226 to expand to generate a negative pressure difference, allowing fluid to flow through the inlet valve passage 221 into the pressure chamber 226, after which After the direction of the electric field applied to the actuator 242 is changed, the actuator 242 will cause the lowering deformation pressure chamber 226 of the actuating device 24 to contract and reduce the volume, causing the pressure chamber 226 to generate a positive pressure difference from the outside, causing the fluid to be caused by The outlet valve passage 222 flows out of the pressure chamber 226. At the same time, some of the fluid also flows into the inlet valve passage 221 and the inlet temporary chamber 223, however, due to the inlet valve structure 231 at this time (as shown in the sixth figure (c) (shown) is a state in which the pressure is closed, so that the fluid does not flow backward through the inlet valve piece 231, and the fluid temporarily stored in the inlet temporary chamber 223 is actuated by the actuator 1376455 242 re-powered Actuation, the actuating means 24 repeats again when the convex deformation increases the volume of the pressure chamber 226, and then from the inlet to the inlet buffer cavity 223 through the 'pressure passage 221 flows into the pressure chamber 226, for delivery of fluid. In addition, the valve body cover 22 also has a plurality of groove structures. In this embodiment, the upper surface 220 of the valve body cover 22 has a groove 227 disposed around the pressure chamber 226. The lower surface 228 has a groove 224 disposed around the inlet temporary cavity 223, a groove 225 disposed around the valve passage 222, and a groove 229. Similarly, the groove structure is used for sealing. A ring 27 (shown in Figure 7 (a)) is disposed therein. Please refer to the sixth figure (a) and cooperate with the third figure. The sixth figure (a) is the structural diagram of the valve body film shown in the third figure. As shown in the figure, the valve body film 23 is mainly processed by conventional processing. Or yellow light etching, or laser processing, or electroforming processing, or electric discharge machining, and is a sheet structure having substantially the same thickness, and having a plurality of hollow valve switches thereon, including the first valve opening φOFF and the second valve switch, in the present embodiment, the first valve opening relationship is the inlet valve structure 231, and the second valve opening relationship is the outlet valve structure 232, wherein the inlet valve structure 231 has the inlet valve piece 2313 and a plurality of hollow holes 2312 disposed around the periphery of the inlet valve piece 2313, and further having an extension portion 2311 connected to the inlet valve piece 2313 between the holes 2312, when the valve body film 23 is subjected to a transfer from the pressure chamber 226 When the downward stress is applied, as shown in the seventh figure (4), the inlet valve structure 231 is entirely flatly attached to the valve body seat 21, and the inlet valve piece 2313 abuts against the protruding portion of the sealing ring 26 on the groove 216. And sealing the valve body seat 21 The upper opening 12 1376455 and the opening 213, and the hollow hole 2312 and the extending portion 2311 of the periphery thereof are floated on the valve body seat 21, so that the closing of the inlet valve structure 231 prevents the fluid from flowing out. When the valve body film 23 is subjected to the suction of the pressure chamber 226, the sealing ring 26 provided in the groove 216 of the valve body seat 21 has provided the inlet valve structure 231 - Preforce (Preforce) Therefore, the inlet valve piece 2313 can be made to have a larger pre-I-covering effect by the support of the extension portion 2311 to prevent backflow, and the inlet valve structure 231 is displaced upward due to the negative pressure of the pressure chamber 226 ( As shown in FIG. 6(b), at this time, the fluid can flow from the valve body seat 21 to the inlet temporary storage chamber 223 of the valve body cover 22 via the hollow hole 2312, and through the inlet temporary storage chamber 223 and the inlet. The valve passage 221 is transferred into the pressure chamber 226, so that the inlet valve structure 231 can be quickly opened or closed in response to the positive and negative pressure difference generated by the pressure chamber 226 to control the ingress and egress of the fluid and prevent the fluid from flowing back. To the valve body seat 21. • Similarly, another valve structure located on the same valve body film 23 is the outlet valve structure 232, wherein the outlet valve piece 2323, the extension portion 2321, and the hole 2322 are operated in the same manner as the inlet valve structure 231, and thus are no longer To be described, the seal ring 26 around the outlet valve structure 232 is disposed in a direction opposite to the seal ring 27 of the inlet valve structure 231, as shown in the sixth diagram (c), thus when the pressure chamber 226 is compressed to generate a thrust. The seal ring 27 disposed in the recess 225 of the valve body cover 22 will provide an outlet valve structure 232 - Preforce, such that the outlet valve piece 2323 can be produced by the extension 2321 to create a larger cover. The tight effect prevents the reverse flow at 13 1376455. When the outlet valve structure 232 is displaced downward due to the positive pressure of the pressure chamber 226, the fluid can be passed from the pressure chamber 226 through the valve body cover through the hollow hole 2322. 22 flows into the outlet temporary chamber 215 of the valve body seat 21, and can be discharged through the opening 214 and the outlet flow passage 212, so that the fluid can be self-pressure chamber via the mechanism of opening the outlet valve structure 232. Within 226 escape, in order to achieve delivery of the functional fluid. Please refer to the seventh diagram (a), which is a schematic diagram of the unactuated state of the fluid delivery device of the preferred embodiment of the present invention. In this embodiment, all the groove structures 216, 217, 218 are respectively provided with a sealing ring 26, and A sealing ring 27 is also disposed in the recesses 224, 225, and 229, and is made of a rubber material which is excellent in chemical resistance, and is not limited thereto. The recess 216 is disposed on the valve body seat 21 around the opening 213. The inner sealing ring can be a ring structure having a thickness greater than the depth of the groove 216, so that the sealing ring 26 disposed in the groove 216 protrudes from the upper surface 210 of the valve body seat 21 to form a micro convex structure. Therefore, the inlet valve piece 2313 of the inlet valve structure 231 of the valve body film 23 which is disposed on the valve body seat 21 is formed with an upward convexity due to the micro convex structure of the sealing ring 26, and the rest of the wide body film 23 is The valve body cover 22 abuts against the top, such that the micro-convex structure pushes the inlet valve 231 to generate a pre-force effect, which contributes to a greater pre-covering effect to prevent backflow, and since the sealing ring 26 is upward The raised micro-convex structure is located in the valve body The inlet valve structure 231 of the membrane 23 is such that the inlet valve structure 231 has a gap between the inlet valve piece 2313 and the upper surface 210 of the valve body seat 21 when not in operation, and similarly, when the sealing ring 27 is disposed around the outlet When the groove 225 of the valve passage 222 is disposed, the sealing ring 27 is disposed on the lower surface 228 of the body cover 22 of the 1376455, so that the sealing ring 27 protrudes downward from the outlet valve structure of the valve body film 23. a micro-convex structure bulging downwardly from the valve body' cover 22, the micro-convex structure being disposed only in a reverse direction to the micro-convex structure formed in the inlet valve structure 231, but the functions are the same as described above, and thus Let me repeat. The remaining seal rings 26, 27 and 28 respectively disposed in the groove structures 217, 218 and 224, 229 and 227 are mainly used to respectively form the valve body seat 21 and the valve body film 23, the valve body film 23 and the valve body. When the lid body 22 and the valve body cover 22 are in close contact with the actuating device 24, fluid leakage is prevented. Of course, the above-mentioned micro-convex structure is formed by using a groove and a sealing ring. In some embodiments, the micro-convex structure of the valve body 21 and the valve body cover 22 can also be a semiconductor process, for example, yellow etching. Or coating or electroforming technology is formed directly on the valve body seat 21 and the valve body cover 22. Please also refer to the seventh figure (a), (b), (c), as shown in the figure, when the cover body 25, the actuating device 24, the valve body cover 22, the valve body film 23, the sealing ring 26 φ and the valve After the body seats 21 are assembled and arranged correspondingly, the opening 213 of the valve body seat 21 corresponds to the inlet valve structure 231 on the valve body film 23 and the inlet valve passage 221 on the valve body cover 22, and the valve body seat 21 is The opening 214 corresponds to the outlet valve piece 232 on the valve body film 23 and the outlet valve passage 222 on the valve body cover 22, and since the sealing ring 26 is disposed in the groove 216, the inlet of the valve body film 23 is formed. The wide door structure 231 is slightly raised above the valve body seat 21, and a pre-force is generated by the seal ring 26 located in the recess 216 contacting the valve body film 23, so that the inlet valve structure 231 is When not actuated, a gap is formed with the upper surface 15 1376455 210 of the valve body seat 21. Similarly, the outlet valve structure 232 is also disposed under the valve body cover 22 by the same manner as the sealing ring 27 is disposed in the recess 225. The surface 228 forms a gap. When the actuator 242 is driven by a voltage, the actuator 24 produces a bend. Deformation, as shown in the seventh diagram (b), the actuating device 24 is bent upwardly in the direction indicated by the arrow a, so that the volume of the pressure chamber 226 is increased, thereby generating a suction force, so that the inlet of the valve body film 23 The valve structure 231 and the outlet valve structure 232 are subjected to an upward pulling force, and the inlet valve piece 2313 of the inlet valve structure 231 having a pre-force (Preforce) is quickly opened (as shown in FIG. 6(b)) to make the liquid A large amount of inlet passage 211 from the valve body seat 21 can be sucked in, and flows through the opening 213 of the valve body seat 21, the hole 2312 of the inlet valve structure 231 on the valve body film 23, and the wide body cover 22 The inlet temporary storage chamber 223 and the inlet valve passage 221 flow into the pressure chamber 226. At this time, since the inlet valve structure 231 of the valve body film 23 and the outlet valve structure 232 are subjected to the upward pulling force, the outlet valve at the other end is located. The structure 232 is such that the upward pulling force causes the outlet valve piece 2323 on the valve body film 23 to seal the outlet valve passage 222, so that the outlet valve structure 232 is closed, and thus the fluid flows backward. When the actuating device 24 changes due to the direction of the electric field, When the arrow b shown in the seventh figure (4) is bent downward, the volume of the pressure chamber 226 is compressed, so that the pressure chamber 226 generates a thrust to the internal fluid, and the inlet valve structure 231 of the valve body film 23 is formed. The outlet valve structure 232 is subjected to a downward thrust. At this time, the outlet valve piece 2323 of the outlet valve structure 232 disposed on the seal ring 27 in the recess 225 can be quickly opened (as shown in FIG. 6 (c), 16 1376455). And the liquid is vented instantaneously, and the pressure chamber 226 is passed through the valve body cover.
