Some exemplary embodiments embodying the features and advantages of the present invention are described in detail in the following description. It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and drawings are intended to be illustrative and not limiting.

The fluid transfer device of the electrical energy conversion mechanical energy of the present invention is for conveying a fluid, comprising a power input device, an actuator, a fluid inlet device and a fluid outlet device, wherein the power input device can receive the electric energy, and the electric energy drive The actuator, by movement of the actuator, causes the fluid to be directed to the fluid outlet device via the fluid inlet device.

Please refer to the first figure and the second figures A to C, which are structural diagrams of a preferred embodiment of the fluid transfer device for electrical energy conversion mechanical energy of the present invention. As shown in the figure, the fluid transfer device for the electrical energy conversion mechanical energy further includes a The base 11, the valve cover 12, a valve film 13 and a cover 15. The actuator 14 is integrally assembled by a vibrating film 141 and a movable piece 142, and is assembled by the cover 15 above the valve cover 12.

The base 11 has an inlet flow passage 111 for communication with the fluid inlet means, and an outlet flow passage 112 for communicating with the fluid outlet means such that fluid can be externally input to the base 11 via the inlet flow. The passage 111 is conveyed to an opening 113 of the base 11 and controlled by the valve body of the diaphragm cover 12 and the vibrating membrane 13, and then flows into the outlet flow passage 112 via an opening 114 to be connected to the fluid outlet means.

The valve cover 12 is disposed on the base 11 and is stacked with the base 11 to form an inlet valve portion and an outlet valve portion, and a portion of the upper surface 120 is recessed to form a pressure chamber 125 for And the inlet valve portion and the outlet valve portion; the inlet valve portion includes a valve passage 122 extending through the upper surface 120 to the lower surface 121 of the valve cover 12, an inlet temporary cavity 124 at the lower surface 121, and a The micro-convex structure 16 around the opening 113 of the susceptor 1 and the outlet valve portion include a valve passage 123 extending through the upper surface 120 to the lower surface 121 of the bonnet seat 1, and a valve passage 123 located at the lower surface 121. The micro-convex structure 16 and an exit temporary cavity 115 are connected above the opening 114 of the susceptor 1.

The valve film 13 is mainly a sheet structure having substantially the same thickness, and is disposed between the base 11 and the valve cover 12, and is partially hollowed out corresponding to the inlet valve portion and the outlet valve portion. The valve plate structure 131, 132, and the valve plate structure 131, 132 is in contact with the inlet valve portion and the micro-convex structure 16 of the outlet valve portion to generate a pre-force action (PREFORCE) to correspondingly close the base 1 The opening 113 and the valve passage 123 of the valve cover seat 12 can further close the inlet flow passage 111 and the outlet flow passage 112 of the base 1.

In addition, the base 1 and the inlet valve portion and the outlet valve portion of the valve cover 12 are respectively provided with a recess 17 for inserting the sealing member 18 to prevent the inlet valve portion and the outlet valve portion. A fluid leak occurs; and the bonnet 12 is clamped to the cover 15 and the actuator 14 is also provided with a recess 17 for insertion with the sealing member 18 to prevent the bonnet 12 from being placed. A fluid leak occurs in the pressure chamber 125.

Furthermore, the actuator 14 is assembled on the valve cover 12 to cover the pressure chamber 125, and the actuator is caused by electric energy to cause a deformation phenomenon of the actuator 14, or the actuator 14 is actuated. The actuator generates a rotating or vibrating phenomenon due to the action of electric energy and magnetic field.

Please also refer to the second diagrams A, B, and C. As shown in the figure, when the power input device receives an electric energy, the electric energy is transmitted and the actuator 14 is driven. At this time, the actuating piece 142 of the actuator 14 will be The deformation phenomenon occurs due to the electric field generated by the electric energy. As shown in the second figure B, the actuator 14 is bent upward in the direction indicated by the arrow a, so that the volume of the pressure chamber 125 is increased, thereby generating a suction force. The valve film 13 is subjected to an upward stress, and the valve structure 131 having a pre-stress (PREFORCE) is quickly opened, so that the liquid can be sucked in a large amount from the fluid inlet device and the inlet passage 111 on the base 11. And flowing into the pressure chamber 125 through the opening 113 on the base 11, the valve plate structure 131 on the valve film 13, the inlet temporary cavity 124 on the valve cover 12, and the valve passage 122. Since the valve film 13 as a whole is subjected to the upward stress, the valve plate structure 132 at the other end seals the valve passage 123 due to the upward stress, so that the valve plate structure 132 at the other end is closed, so that the fluid does not flow out.

When the actuator 14 is bent downward and deformed according to the arrow b shown in the second figure C in response to the change of the electric field direction, the volume of the pressure chamber 125 is compressed, so that the pressure chamber 125 generates a thrust to the internal fluid. The valve film 13 is subjected to a downward stress. At this time, the valve structure 132 at one end can be quickly opened by the pre-force (PREFORCE) provided by the micro-convex structure 16, and the liquid is instantaneously vented by the pressure chamber. 125 flows to the fluid outlet device via the valve passage 123 on the valve cover seat 12, the valve plate structure 132 at the end of the valve film 13 , the outlet temporary chamber 115 on the base 11 , the opening 114 and the outlet flow passage 112 . Thus the fluid transfer process is completed. Similarly, at this time, since the valve sheet structure 131 at the other end of the valve sheet film 13 is subjected to the downward stress, the opening 113 is sealed, that is, the other end valve structure 131 is closed, so that the fluid is temporarily unable to be input, and by the valve The sheet structures 131 and 132 are matched with the pre-stressing and complete sealing design of the micro-convex structure 16 disposed on the base 11 and the valve cover seat 12, so that the fluid can not be reflowed during the conveying process, thereby achieving high efficiency. transmission.

It can be seen that the fluid transfer device 10 of the electrical energy conversion mechanical energy of the present invention mainly drives the actuator 14 through the electric energy transmission, and the actuator 14 is operated in different forms to cause the fluid to flow from the inlet flow passage 111 of the valve cover seat 12. And circulating to the outlet flow path 112 to flow out. However, in other embodiments, in addition to being deformable in response to an electric field generated by electrical energy, the actuator 14 may cause a rotation or vibration phenomenon in response to a magnetic field, thereby also The volume of the pressure chamber 125 can be compressed, changed, and the fluid is forced to flow from the inlet flow passage 111 of the bonnet seat 12, and circulated to the outlet flow passage 112 for outflow, and the actuator 14 produces different deformation modes of operation. There are a variety of implementations, which may be varied depending on the actual application, and are not limited thereto.

In summary, the fluid transfer device of the electrical energy conversion mechanical energy of the present invention can input electric energy through the electric energy input device to drive the actuator, and the actuator moves to move the fluid from the inlet flow path to the outlet flow path, thereby The transport of fluids effectively converts electrical energy into mechanical energy and achieves efficient transmission.
