INSTRUCTIONS: [Technical field to which the invention pertains] This case relates to a large-flow fluid delivery device, and more particularly to a large-flow fluid delivery device suitable for a micro-pump structure. [Prior Art] In all fields, whether it is pharmaceutical, computer technology, printing, energy and other industrial products, the products are developing in the direction of refinement and miniaturization. Among them, micro-purchon nozzles, inkjet heads, industrial columns The fluid transport structure contained in products such as printing devices is its key technology. Therefore, how to break through its technical bottlenecks through innovative structures 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-pull structure system includes an inlet channel, a microactuator 15, a transmission block 14, and a compartment. The film 12, the squeezing chamber 1U, the substrate ❹u: and the outlet channel 16 define a compression chamber 111 between the substrate n and the interlayer film 12, mainly for recording liquid, which will be affected by the deformation of the interlayer film 12. The Zhao product of the (4) contraction chamber m was 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 11 , due to the slight The actuator 15 is again placed on the transmission block 14, so that the transmission block 14 can transmit the thrust of the microactuator 15 to the interlayer film 12, so that the interlayer film 12 is also deformed by being squeezed, that is, as shown in the first figure. B is thousands, and six _day r is as shown in Figure 13. The liquid can flow according to the arrow in the figure. 200938729 • Flow, so that the liquid that is stored in the compression chamber 111 after flowing in through the inlet channel 13 is subjected to Squeeze and flow through the outlet passage 16 to other pre-set spaces for the purpose of supplying fluid. Please refer to the second figure, which is a top view of the micro-push structure shown in FIG. A. 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. In the direction indicated, 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 passage 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 Φ and out of the outlet flow passage 192 through 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 large-flow fluid transport device that can improve the above-mentioned conventional techniques is an urgent problem to be solved. 7 200938729 [Summary of the Invention] The main purpose of the present invention is to provide a high-flow fluid delivery device that solves the problem of the flow of fluid in the micro-pump structure of the prior art during fluid transfer.

As shown, the valve body cover 22 has an upper surface 220 . And the lower surface 228, and the valve body cover 22 also has an inlet valve door passage 221 and an outlet valve passage 222 extending through the upper surface 22A to the lower surface 228, and the inlet valve passage 221 is disposed at the valve body seat The opening 213 of the 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 embodiment, the valve body film 23 and The first temporary storage chamber formed between the valve body cover 22 is the inlet temporary storage chamber 223 shown in the drawing, and is not limited thereto, and is formed by the lower surface 228 of the valve body cover 22 and the inlet. The corresponding position of the valve passage 221 is partially recessed and communicated with the inlet valve passage 221. 200938729 ' Please refer to the fifth figure B, which is a sectional 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. Corresponding to the actuator 242 of the actuating device 24, 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 actuated The actuator 242 is biased by the voltage to cause the actuator 24 to be convexly deformed, causing 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, and thereafter, when applied After the direction of the electric field of the actuator 242 is changed, the actuator 242 will contract the lower deformation pressure chamber 226 of the actuating device 24 to reduce the volume, causing the pressure chamber 226 to generate a positive pressure difference from the outside, thereby promoting the fluid The outlet valve passage 222 flows out of the pressure chamber 226. At the same time, some of the flow impurities also flow into the inlet wide door passage 221 and the inlet temporary storage chamber 223, however, due to the inlet valve structure 231 at this time (as shown in the sixth figure) C is shown to be pressed The state of the fluid so that the fluid does not flow back through the inlet valve plate 231, as for the fluid temporarily stored in the inlet temporary chamber 223, is then actuated at the actuator 242 to repeat the actuation. When the device 24 is again convexly deformed to increase the volume of the pressure chamber 226, the inlet temporary chamber 223 flows into the pressure chamber 226 through the inlet valve passage 221 to perform fluid transportation. In addition, the valve body cover 22 also has a plurality of groove structures. In the embodiment, the upper surface 22 of the valve body cover 22 has a groove 227 disposed around the pressure chamber 226. On the lower surface 228, there is a groove 224 disposed around the inlet temporary storage chamber 223, a groove 225 surrounding the outlet valve passage 222, and a groove 229. Similarly, the above-mentioned 11 200938729 • groove structure is used for A seal ring 27 (shown in Figure 7A) is placed in the middle of it - see Figure 6 and in conjunction with the third figure, where the sixth figure A is the valve body film shown in Figure 3. Schematic diagram, as shown in the figure, the valve body film 23 is mainly produced by conventional processing, or yellow light etching, or laser processing, or electroforming processing, or electric discharge machining, and is a sheet having substantially the same thickness. The structure has a plurality of hollow valve switches including a first valve switch and a second valve switch. In this embodiment, the first valve opening relationship is an inlet® valve structure 231, and the second valve opening relationship is an outlet valve. Structure 232, wherein the inlet valve structure 231 is attached 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 interlayer film 23 is subjected to a self-pressure chamber When the chamber 226 transmits downward stress, as shown in FIG. 7C, the inlet valve structure 231 is entirely flatly attached to the valve body seat 21, and the inlet valve piece 2313 is sealed against the recess 216. The ring 26 protrudes from the opening 213 of the valve body seat 21, and the hollow hole 2312 and the extension portion 2311 of the outer periphery thereof are floated on the valve body seat 21, so that the closing of the inlet valve structure 231, Keep the fluid out of the flow. When the valve body film 23 is subjected to the suction generated by the volume increase of the pressure chamber 226, the seal ring 26 provided in the groove 216 of the valve body seat 21 has provided the inlet valve structure 231 - Preforce. Therefore, the inlet valve piece 2313 can generate a larger pre-covering effect by the support of the extension portion 2311 to prevent backflow, and when the pressure is negative due to the pressure chamber 226, the 12:38738729-mouth door structure 231 is The displacement is generated (as shown in Figure 6B). At this time, the fluid can flow from the valve body seat 21 to the inlet temporary chamber 223' of the valve body cover 22 through the hollow hole 2312 and temporarily stored through the inlet. The chamber 221 is transferred into the pressure chamber 226, so that the inlet door 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 flow in and out of the fluid. And the fluid does not flow back to the valve body seat 21. 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 no longer 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 FIG. 6C, thus setting when the pressure chamber 226 is compressed to generate a thrust. The seal ring 27 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 of the extension 2321 to create a greater pre-tightening Effect to prevent backflow 'When the outlet door 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 22 via the hollowed hole 2322. Flowing into the outlet temporary chamber 215 of the valve body seat ' can be discharged through the opening 214 and the outlet flow passage 212, so that the fluid can be drained from the pressure chamber 226 via the mechanism of opening the outlet valve structure 232. Out In order to achieve delivery of the functional fluid. Please refer to FIG. 7A, 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 junctions 13 200938729 'structures 216, 217, 218 are respectively provided with sealing rings. 26' and the grooves 224, 225, and 229 are also respectively provided with a sealing ring 27' which is made of a rubber material which is excellent in chemical resistance, and is not limited thereto, and is disposed on the valve body seat 21 The seal ring in the recess 216 of the opening 213 may be a ring structure having a thickness 姗 greater than the depth of the recess 216 such that the seal ring 26 disposed in the recess 216 protrudes from the upper surface of the valve body seat 21. The 210 forms a micro-convex structure, so that the inlet valve piece 2313 of the inlet valve structure 231 of the valve body film 23 disposed on the valve body seat 21 is shaped like an upward bulge due to the micro-convex structure of the seal ring 26, and the valve The remaining portion of the body film 23 is abutted against the valve body cover 22 so that the micro-twisted structure pushes the inlet door 231 to produce a pre-force effect, which contributes to a greater pre-tightening effect. Prevent backflow' and because the seal ring 26 is uplifted The convex structure is located at the inlet valve structure 231 of the valve body film 23, so that the inlet valve structure 231 has a gap between the inlet piece 2313 and the upper surface 210 of the valve body seat 21 when not in operation, and similarly, when sealing When the ring 27 is disposed in the groove 225 surrounding the outlet valve door passage 222, since the seal ring 27 is disposed on the lower surface 228 of the valve body cover 22, the seal ring 27 is the outlet valve of the valve body film 23. The structure protrudes downward to form a micro-convex structure that bulges downwardly from the valve body cover 22. The micro-convex structure is only disposed opposite to the micro-convex structure formed in the inlet valve structure 231, but its function is The foregoing is the same 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. The lid body 22 and the valve body cover 22 and the actuating device 24 are closely attached to the 200938729' to prevent fluid leakage. Of course, the above-mentioned micro-convex structure is formed by using a groove and a sealing ring. In some embodiments, the micro-frame 21 and the valve body cover 22 may also be formed by a semiconductor process, for example, yellow. Photoetching or coating or electroforming techniques are formed directly on the valve body seat 21 and the valve body cover 22. Please refer to FIG. 7A, B, and C at the same time. 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 seal ring 26 and the valve body seat 21 are assembled correspondingly with each other, Thereafter, the opening 213 of the valve body seat 21 corresponds to the inlet valve structure 231 on the valve body membrane 23 and the inlet valve passage 221 on the valve body cover 22, and the opening 214 on the valve body seat 21 is connected to the valve The outlet valve piece 232 on the body film 23 and the outlet valve passage 222 on the valve body cover 22 correspond to each other, and since the seal ring 26 is disposed in the groove 216, the inlet valve structure 231 of the valve body film 23 is slightly convex. Above the valve body seat 21, a pre-force 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 in contact with the valve when it is not actuated. The upper surface 210 of the body seat 21 forms a gap. Similarly, the outlet valve structure 232 also forms a gap with the lower surface 228 of the valve body cover 22 in the same manner as the seal ring 27 is disposed in the recess 225. When a voltage drives the actuator 242, the actuating device 24 produces a bending deformation, such as As shown in Fig. 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, and the inlet valve structure 231 and the outlet valve of the valve body film 23 are formed. The structure 232 is subjected to an upward pulling force and has a pre-stress 15 200938729
