Abstract

The invention discloses a biplane oil driven micropump based on a giant magnetostrictive film driver. The biplane oil driven micropump comprises a pump body, and a substrate dividing the pump body into an upper pump body and a lower pump body, wherein an upper plane spiral coil is arranged on the upper surface of the upper pump body; the upper plane spiral coil is electrically connected with an external power supply; a positive magnetostrictive effect film is arranged on the upper surface of the substrate; an inverse magnetostrictive effect film is arranged on the lower surface of the substrate; a liquid inlet and a liquid outlet are formed in the pump body; a valve cavity is arranged in the pump body; the substrate forms an upper liquid cavity with the upper pump body and forms a lower liquid cavity with the lower pump body; both the liquid inlet and the valve cavity are communicated with the upper and lower liquid cavities; the valve cavity is communicated with the liquid outlet; one-way liquid inlet films are arranged in positions where the upper and lower liquid cavities are connected with the liquid inlet; one-way liquid outlet films are arranged in positions where the upper and lower liquid cavities are connected with the valve cavity. The biplane oil driven micropump adopts double liquid cavities, and has a larger pump cavity in the condition of the same volumes, with the flow being larger than that of the conventional film micropump.

Description

technical field [0001] The invention relates to the technical field of micropumps, in particular to a double-planar coil-driven micropump based on a giant magnetostrictive film driver. Background technique [0002] Micro-mechanical systems (MEMS) have developed rapidly in recent years. As an important power component in micro-fluidic devices, micro-pumps are the core components of micro-flow control systems. Because it can accurately detect and control the flow, it has great application prospects in the fields of micro-delivery of drugs, micro-injection of fuel, synthesis of DNA, cooling of integrated electronic components, microchemical analysis, and propulsion of micro-satellites. At present, the drive methods that have been widely used in micropumps include electrostatic drive, electromagnetic drive, piezoelectric drive, thermal drive, bimetal effect drive, shape memory alloy drive, and thin-film giant magnetostrictive material drive. Piezoelectric drive and electrostati...
