Problems solved by technology

[0006] This kind of micropump structure 10 without physical valves is prone to a large amount of backflow of fluid, so in order to increase the flow rate, the compression chamber 111 needs to have a larger compression ratio , in order to generate enough chamber pressure, it needs to spend a higher cost on the actuator 15

Abstract

The present invention relates to a fabrication method of a fluid-conveying device. The method includes the following steps: a valve body layer is formed; a valve body cover layer, which is provided with a pressure chamber, is correspondingly formed on the valve body layer; a flexible film, which is provided with a plurality of valve plate structures, is formed; an actuating film is formed; an actuating plate is formed and attached on the actuating film to form an actuator; the flexible film is arranged between the valve body layer and the valve body cover layer; the valve body layer, the flexible film and the valve body cover layer are assembled together and positioned; and the actuator is arranged on the valve body cover layer, so that the actuating film can seal the pressure chamber of the valve body cover layer to form the fluid-conveying device.

Description

technical field [0001] The invention relates to a manufacturing method of a fluid delivery device, in particular to a manufacturing method of a fluid delivery device suitable for a micropump structure. Background technique [0002] At present, in various fields, whether it is medicine, computer technology, printing, energy and other industries, products are developing towards refinement and miniaturization. Among them, the fluid delivery structures included in products such as micropumps, sprayers, inkjet heads, and industrial printing devices As its key technology, how to break through its technical bottleneck with the help of innovative structure is an important content of development. [0003] Please refer to Fig. 1 (a), it is the structural representation of known micropump structure when not actuating, and known micropump structure 10 comprises inlet channel 13, microactuator 15, transmission block 14, interlayer film 12, The compression chamber 111, the base plate 11 ...
