Abstract

The invention provides multifunctional protective glasses based on electrowetting micro-fluidic driving and a method, an electrode channel and three liquid storage containers are arranged in a lens substrate, and orange deionized water, blue deionized water and a 0.2 mol / L Fe2 (SO4) 3 solution are stored in the three liquid storage containers respectively; the electrode channel is formed by sequentially connecting three liquid outlet channels, a mother electrode channel and a plurality of rows of sub electrode channels, the lower end of one liquid outlet channel is correspondingly communicated with the left side of one liquid storage container, the upper ends of the three liquid outlet channels are jointly communicated with the mother electrode channel which is horizontally arranged left and right and is located over the three liquid storage containers, the plurality of rows of sub electrode channels are arranged right above the mother electrode channel, the lower ends of the sub electrode channels are communicated with the mother electrode channel, and the mother electrode channel, each liquid outlet channel and each row of sub electrode channels are formed by front polar plates and rear polar plates. A programmable chip is used for controlling electrode time sequence voltage, liquid drops are adsorbed on a conductive substrate and move under the action of voltage based on electrowetting micro-fluidic driving, the automation degree is high, and liquid filling is rapid and uniform.

Description

technical field

[0001] The invention belongs to the technical field of optical glasses, and in particular relates to multifunctional protective glasses driven by electrowetting microfluidics, which are used to protect harmful rays such as strong light, glare, blue light and ultraviolet rays. Background technique

[0002] Artificial light on electronic screens is everywhere. Driving at night will cause glare, and there will be ultraviolet rays when going out. All kinds of harmful light will aggravate the fatigue of the eyes. At present, microfluidic color-changing protective glasses are mainly based on manual-driven liquid filling, thermopneumatic-driven micropumps, valveless piezoelectric-driven micropumps, and shape-memory alloy-driven micropumps. Manual drive needs to drive the liquid by hand, and the degree of automation is low; due to the low expansion rate of the gas, the pump body outputs less liquid, which is not suitable for large-area discoloration of the glasses le...

Embodiment Construction

[0028] see figure 1 , the multi-function protective glasses of the present invention have spectacle frame and left and right two eyeglasses 1, and two eyeglasses 1 are fixed on the spectacle frame, and switch, programmable chip 3 and respectively are respectively installed on the left and right sides frame feet of spectacle frame. Power supply 4, there are three switches on each frame foot, orange deionized water switch 21, blue deionized water switch 22 and Fe 2 (SO 4 ) 3Solution switch 23. The orange deionized water switch 21 is installed on the rearmost side of the frame leg, the blue deionized water switch 22 is on the front side of the orange deionized water switch 21, and the Fe 2 (SO 4 ) 3 Solution switch 23. The three switch buttons are circular, the same size, and the front and back positions are equidistant. Fe 2 (SO 4 ) 3 What solution switch 23 front sides are installed is power supply 4, and power supply 4 voltage is 60V, and what power supply 4 front si...
