Versatile Soft Pumps for Fluid Transfer

Abstract

A multifunctional soft pump for fluid transmission, which includes an air pressure control module, an intermediate film and a fluid transmission module, the air pressure control module can control the volume change of the fluid transmission module chamber under the pressure of air pressure, and the air pressure control module It includes an air pressure control chamber and a pressure relief chamber. The intermediate film is located between the air pressure control module and the fluid transmission module, and is used to separate the air pressure control module and the fluid transmission module to form a closed chamber structure. The fluid transmission module includes a fluid control module. A cavity and a fluid transmission hole, the fluid transmission cavity can transmit fluid in one direction and can pump fluid according to the change of the volume of the chamber. The multi-functional soft pump of the invention has good environmental adaptability, simple structure, light weight and no noise, can transport fluid in one direction and play the role of a one-way valve, and can realize the pumping function of fluid through pneumatic drive.

Description

technical field [0001] The invention belongs to the field of fluid transportation, and relates to a multifunctional soft pump for fluid transportation, in particular to a fully soft multifunctional pneumatic soft pump capable of realizing the functions of one-way fluid transmission and fluid pumping.
