Abstract

The invention relates to a manufacturing method of a multi-flow passage fluid conveying device. The method comprises the following steps: a valve body layer is formed and is provided with at least one. The invention relates to a manufacturing method of a multi-flow passage fluid conveying device. The method comprises the following steps: a valve body layer is formed and is provided with at least one inlet channel and at least one outlet channel; a valve body cover layer is correspondingly formed on the valve body layer and is provided with a pressure chamber; a flexible film is formed and is pro inlet channel and at least one outlet channel; a valve body cover layer is correspondingly formed on the valve body layer and is provided with a pressure chamber; a flexible film is formed and is provided with a plurality of valve (plate) structures, the valve structures have equal thickness and are made of identical material, and the rigidity of at least one valve structure is different from thavided with a plurality of valve (plate) structures, the valve structures have equal thickness and are made of identical material, and the rigidity of at least one valve structure is different from that of other valve structures; an actuating device is formed; the flexible film is arranged between the valve body layer and the valve body cover layer, and valve body layer, the flexible film and the vt of other valve structures; an actuating device is formed; the flexible film is arranged between the valve body layer and the valve body cover layer, and valve body layer, the flexible film and the valve body cover layer are mutually assembled and positioned; and the actuating device is used for sealing the pressure chamber of the valve body cover layer to form a multi-flow passage fluid convey in valve body cover layer are mutually assembled and positioned; and the actuating device is used for sealing the pressure chamber of the valve body cover layer to form a multi-flow passage fluid conveying device.g 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 multi-channel 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] see figure 1 , which is a structural schematic diagram of a known micropump structure. The known micropump structure 10 is composed of a valve body seat 11, a valve body cover 12, a valve body film 13, a microactuator 14 and a cover body 15, wherein, The valve body f...

AI Technical Summary

Problems solved by technology

[0007] The main purpose of the present invention is to provide a manufacturing method of a multi-channel fluid delivery device to solve the problem of mixing two different liquids in different proportions with the known micropump structure, which needs to be drawn by two pumps according to different proportions and then stirred Mixing, or using only one pump, but it must be equipped with an external flow regulating valve, which will increase the complexity of the entire pump system and other disadvantages
