Title:
FLUID QUANTITATIVE SUPPLY DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/252604
Kind Code:
A1
Abstract:
A fluid quantitative supply method. By applying an external force to a substrate (1), the micro holes (11) located on the substrate (1) are stressed to deform, and the micro holes (11) use a surface where an axial central position thereof is located as a reference surface, and perform multi-dimensional gradual expansion and contraction at the axial two ends of the reference surface, so as to achieve the entrance and discharge of a fluid by means of the micro holes (11). The fluid is conveyed from one surface of the substrate (1) to the other surface, and the micro holes (11) are used as fluid conveying pipes, thereby achieving the quantitative conveyance of the fluid by means of precise control. A fluid quantitative supply device, comprising: a micro-deformation region (16) is controlled by means of a servo driving body (2) to deform, and the micro holes (11) are enabled to use the surface where the axial central position thereof is located as the reference surface, and perform multi-dimensional gradual expansion and contraction at the axial two ends of the reference surface. The device is artful in design, and by using a microstructure design idea, performs quantitative separation on fluid molecules by means of micro-nanoscale micro holes (11), thereby achieving quantitative conveyance.
