Abstract

The invention belongs to the technical field of microfluid control and in particular relates to a novel piezoelectric driving microfluid mixer and a preparation technology thereof. The microfluid mixer consists of a base body, a base plate, a top plate and a circular piezoelectric vibrator, wherein the base body comprises an inlet, an inlet cavity, a passive mixing unit, a conical inlet end opening, a lower pump cavity, a conical series end opening, a horizontal series channel, a vertical series channel and an upper pump cavity. According to the novel piezoelectric driving microfluid mixer, the upper pump cavity and the lower pump cavity form a serially connected structure and share the circular piezoelectric vibrator; the passive mixing unit consists of a plurality of groups of staggered tri-prism bulges. The novel piezoelectric driving microfluid mixer has the main advantages that a main mixing function and a pumping function for fluid are structurally combined together, and the pumping process of microfluid is also the full mixing process of microfluid; due to the serially connected pump structure, the pumping flow and the pumping pressure are obviously increased; the main structure is prepared by a micro injection molding technology for a thermoplastic polymer material; the novel piezoelectric driving microfluid mixer has the characteristics of low cost, high biological compatibility, suitability for batch production and the like.

Description

technical field [0001] The invention belongs to the technical field of microfluidics, and in particular relates to a novel piezoelectric-driven microfluidic mixer and a preparation process thereof. Background technique [0002] Driven by the development of microelectromechanical systems (MEMS), microfluidic technology has developed extremely rapidly in recent years, and microfluidic devices have been widely used in the fields of biology, medical treatment and food. In the working process of various microfluidic devices, the mixing of two or more microfluids is the key technology, so most of the occasions are almost inseparable from an important functional device: microfluidic mixer, its main function It is to realize the rapid and efficient mixing of micron or even nanoscale fluids. [0003] At present, many researchers at home and abroad have done a lot of work on microfluidic mixers and developed various microfluidic mixers. According to different working methods, existi...
