Description

technical field [0001] The invention relates to a fluid delivery device, in particular to 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 through 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 film 13 includes an inlet valve structure 131 and an outlet va...

AI Technical Summary

Problems solved by technology

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