Description

流體閥座Fluid seat

本案係關於一種流體閥座,尤指一種適用於流體輸送裝置之流體閥座。This case relates to a fluid valve seat, and more particularly to a fluid valve seat suitable for use in a fluid delivery device.

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、噴霧器、噴墨頭、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,為發展之重要內容。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 them, products such as micro-pumps, sprayers, inkjet heads, industrial printing devices, etc. The fluid transport structure is its key technology, which is how to break through its technical bottleneck with innovative structure and be an important part of development.

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。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, and a partition. The film 12, the compression chamber 111, the substrate 11 and the outlet channel 16 define a compression chamber 111 between the substrate 11 and the interlayer film 12, mainly for storing liquid, which will be compressed by the deformation of the interlayer film 12. The volume of chamber 111 is altered.

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內的液體受擠壓,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。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 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 predetermined spaces. In order to achieve the purpose of supplying fluid.

請再參閱第二圖,其係為第一圖(a)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內,再由出口擴流器18經出口流道192流出。Please refer to the second figure, which is a top view of the micro-push structure shown in the first figure (a). As shown in the figure, when the micro-push structure 10 is actuated, the direction of fluid transport is indicated by the symbol Y in the figure. As shown by the direction of the arrow, the inlet diffuser 17 is a tapered structure having different opening sizes at both ends, one end of the larger opening is connected to the inlet flow path 191, and one end of the smaller opening is connected to the micro compression chamber 111. 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 through the outlet diffuser 18.

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,所以為促使流率增加,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。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.

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。Therefore, how to develop a fluid delivery device that can improve the above-mentioned conventional technology is an urgent problem to be solved.

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之入口閥門通道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相對應之位置,而出口閥門通道222則設置於與閥體座21之出口暫存腔215內之開口214相對應之位置,並且,於本實施例中,閥體薄膜23及閥體蓋體22之間所形成之第一暫存室即為圖中所示之入口暫存腔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。Please refer to the fifth figure (a) and cooperate with the third figure. The fifth figure (a) is the schematic diagram of the back structure of the valve body cover shown in the third figure. 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 body The opening 213 of the seat 21 corresponds to the position, and the outlet valve passage 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 film 23 The first temporary storage chamber formed between the valve body cover 22 and the valve body cover 22 is the inlet temporary storage chamber 223 shown in the figure, and is not limited thereto, and is formed by the lower surface 228 of the valve body cover 22 The corresponding position of the inlet valve passage 221 is partially recessed and communicated with the inlet valve passage 221.

請參閱第五圖(b),其係為第五圖(a)之剖面結構示意圖,如圖所示,閥體蓋體22之上表面220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內,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內,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內之流體,則於致動器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內,以進行流體的輸送。Referring to FIG. 5(b), which is a cross-sectional structural view of the fifth figure (a), as shown, the upper surface 220 of the valve body cover 22 is partially recessed to form a pressure chamber 226. It is disposed corresponding to the actuator 242 of the actuating device 24, and the pressure chamber 226 communicates with the inlet temporary chamber 223 via the inlet valve passage 221 and simultaneously communicates with the outlet valve passage 222, thus, when the actuator 242 is subjected to voltage actuation to cause the actuator 24 to be convexly deformed, causing the volume of the pressure chamber 226 to expand to create a negative pressure differential, allowing fluid to flow through the inlet valve passage 221 into the pressure chamber 226, and thereafter, when applied to After the direction of the electric field of 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 to urge the fluid from the outlet valve. The passage 222 flows out of the pressure chamber 226. At the same time, part 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 diagram (c) Show) is a state in which it is closed under pressure, so the fluid will not The phenomenon of backflow is generated by the inlet valve piece 231. As for the fluid temporarily stored in the inlet temporary storage chamber 223, the actuator 242 is again actuated by the voltage, and the actuator device 24 is repeatedly deformed again to increase the pressure chamber. When the chamber 226 is in volume, it is again flowed into the pressure chamber 226 from the inlet temporary chamber 223 to the inlet valve passage 221 for fluid transport.

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。In addition, the valve body cover 22 also has a plurality of groove structures. In the embodiment, the upper surface 220 of the valve body cover 22 has a groove 227 disposed around the pressure chamber 226, and the lower surface is provided. The 228 has a groove 224 disposed around the inlet temporary cavity 223, a groove 225 disposed around the outlet valve passage 222, and a groove 229. Similarly, the groove structure is used for a sealing ring 27 (such as The seventh diagram (a) is shown in it.

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(c)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。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 electrical 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 switch And the second valve switch, in the 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 A hollow hole 2312 is provided around the periphery of the inlet valve piece 2313. Further, between the holes 2312, there is an extension portion 2311 connected to the inlet valve piece 2313. When the valve body film 23 is subjected to a pressure from the pressure chamber 226, it is downward. During the stress, as shown in the seventh figure (c), 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 opening 213 on the valve body seat 21, Its periphery and hollow bore 2312 extending portion 2311 to take advantage of sticking to the valve seat 21 above, it is thus acting to close the inlet valve structure 231 of the fluid can not flow out.

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內的密封環26已提供入口閥門結構231一預力(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內,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。When the valve body film 23 is subjected to the suction generated by the volume increase of the pressure chamber 226, since the seal ring 26 disposed in the groove 216 of the valve body seat 21 has provided the inlet valve structure 231 with a preforce, The inlet valve piece 2313 can produce a greater pre-tightening 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 the sixth figure). (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 is transmitted through the inlet temporary storage chamber 223 and the inlet valve passage 221 Into the pressure chamber 226, the inlet valve structure 231 can be quickly opened or closed according to the positive and negative pressure difference generated by the pressure chamber 226 to control the inflow and outflow of fluid and prevent the fluid from flowing back to the valve body seat. 21 on.

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內的密封環27將提供出口閥門結構232一預力(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內,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內洩出,以達到流體輸送之功能。Similarly, the other valve structure 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 will not be described again. However, the sealing ring 26 around the outlet valve structure 232 is disposed in a direction opposite to the sealing ring 27 of the inlet valve structure 231, as shown in the sixth diagram (c), so that when the pressure chamber 226 is compressed to generate a thrust, The seal ring 27 disposed within the recess 225 of the valve body cover 22 will provide a pre-tension of the outlet valve structure 232 such that the outlet valve plate 2323 can be produced by the extension of the extension 2321 to create a greater pre-tightening The effect is to prevent backflow. When the outlet valve structure 232 is displaced downward due to the positive pressure of the pressure chamber 226, the fluid can flow from the pressure chamber 226 through the valve body cover 22 via the hollow hole 2322. It is discharged into the temporary storage chamber 215 of the valve body seat 21 and can be discharged through the opening 214 and the outlet flow path 212. Thus, the fluid can be drained from the pressure chamber 226 via the mechanism of the opening of the outlet valve structure 232. To achieve fluid loss Function.

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內亦分別設置密封環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內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內之密封環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,而閥體薄膜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內時,由於其密封環27係設置於閥體蓋體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內之密封環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。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 surrounding 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 remaining part of the valve 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 at the inlet valve of the valve body film 23 The structure 231 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 likewise, when the sealing ring 27 is disposed in the recess surrounding the outlet valve passage 222. In the groove 225, since the sealing ring 27 is disposed on the lower surface 228 of the valve body cover 22, the sealing ring 27 causes the outlet valve structure of the valve body film 23 to protrude downward to form a downward bulge in the valve body. The micro-convex structure of the cover body 22 is only disposed in the opposite direction to the micro-convex structure formed on the inlet valve structure 231, but its functions are the same as those described above, and thus will not be described again. 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 cover. When the body 22 and the valve body cover 22 are in close contact with the actuating device 24, fluid leakage is prevented.

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。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.

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內,使得閥體薄膜23之入口閥門結構231微凸起於閥體座21之上,並藉由位於凹槽216內之密封環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。Please also refer to the seventh figure (a), (b), (c), as shown, when the cover body 25, the actuating device 24, the valve body cover 22, the valve body film 23, the sealing ring 26 and the valve body After the seats 21 are assembled to each other, 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 membrane 23 and the outlet valve passage 222 on the valve body cover 22, and since the sealing ring 26 is disposed in the recess 216, the inlet valve of the valve body membrane 23 is provided. The 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 not actuated. At the same time, a gap is formed with the upper surface 210 of the valve body seat 21. Similarly, the outlet valve structure 232 is also formed with the lower surface 228 of the valve body cover 22 by the same manner as the sealing ring 27 is disposed in the recess 225. gap.

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、閥體蓋體22上之入口暫存腔223、入口閥片通道221而流入壓力腔室226之內,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。When the actuator 242 is driven by a voltage, the actuating device 24 generates a bending 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 pressure chamber The volume of 226 is increased, thereby creating a suction force that causes the inlet valve structure 231 of the valve body membrane 23, the outlet valve structure 232 to withstand an upward pulling force, and the inlet valve plate of the inlet valve structure 231 having a pre-force (Preforce). The 2313 is rapidly opened (as shown in Fig. 6(b)) so that the liquid can be sucked in a large amount from the inlet passage 211 on the valve body seat 21, and flows through the opening 213 of the valve body seat 21, the valve body film 23 The inlet valve structure 231 hole 2312, the inlet temporary chamber 223 on the valve body cover 22, and the inlet valve passage 221 flow into the pressure chamber 226. At this time, due to the inlet valve structure 231 of the valve body film 23 The outlet valve structure 232 is subjected to the upward pulling force, so that the outlet valve structure 232 at the other end is caused by the upward pulling force so that the outlet valve piece 2323 located on the valve body film 23 seals the outlet valve passage 222, so that the outlet valve structure 232 is closed. Therefore, the fluid flows countercurrently.

當致動裝置24因電場方向改變而如第七圖(c)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對內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內之密封環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上之出口閥門通道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配合設置於閥體座21及閥體蓋體22上之凹槽216、225內的密封環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。When the actuating device 24 is bent downwardly as the arrow b shown in the seventh figure (c) is deformed due to the change of the electric field direction, the volume of the pressure chamber 226 is compressed, so that the pressure chamber 226 generates a fluid to the inside. The thrust force causes the inlet valve structure 231 and the outlet valve structure 232 of the valve body film 23 to receive 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 Figure 6(c)), the liquid is vented in a large amount, and the pressure chamber 226 passes through the outlet valve passage 222 on the valve body cover 22, and the hole 2322 of the outlet valve structure 232 on the valve body film 23. The outlet temporary chamber 215, the opening 214 and the outlet passage 212 on the valve body seat 21 flow out of the fluid delivery device 20, thereby completing the fluid transfer process. Similarly, since the inlet valve structure 231 is subjected to the downward movement. The thrust, thus causing the inlet valve piece 2313 to seal the opening 213, thereby closing the inlet valve structure 231 so that the fluid does not flow back, and is disposed in the valve body seat 21 and the valve body cover by the inlet valve structure 231 and the outlet valve structure 232.
