Problems solved by technology

[0003] Aiming at the technical problems of the existing microfluidic liquid automatic color-changing glasses such as slow discoloration speed, uneven discoloration, short life of the liquid filling device, large volume, and difficulty in integration, the present invention proposes a microfluidic liquid automatic discoloration lens based on piezoelectric drive. The liquid filling device for photochromic glasses can realize the circulation of colored liquid between the lens of photochromic glasses and the liquid storage chamber, and complete the automatic, fast and uniform color changing function. It has a simple structure and small size, which can reach the size of millimeters without affecting the photochromic glasses. The overall volume is comfortable to wear, and the high elastic polydimethylsiloxane (PDMS) organic material is used to prolong the service life

Description

technical field [0001] The invention relates to the technical field of color-changing glasses, in particular to a microfluidic liquid automatic color-changing glasses liquid filling device based on piezoelectric drive. Background technique [0002] At present, the liquid filling methods for microfluidic color-changing glasses mainly include manual-driven liquid filling, thermopneumatic-driven micro-pump liquid filling, valveless piezoelectric-driven micro-pump liquid filling, and shape-memory alloy-driven micro-pump liquid filling. However, due to the fact that the manual-driven liquid filling method is not convenient for manual direct operation in actual use, the flexibility and controllability are poor; the thermopneumatic-driven micro-pump liquid filling method has a low expansion rate of the gas, and the amount of liquid output by the pump body is small , so it is only suitable for small color-changing structures, and the rapidity is poor; the system structure of the val...
