The invention discloses a liquid control micro reversing valve device based on optical driving and a using method thereof. The liquid control micro reversing valve device is characterized in that an air inlet is formed in the bottom of a valve body; an air outlet I and an air outlet II are formed in the top of the valve body in a symmetric manner; a photosensitive liquid droplet I, a photosensitive liquid droplet II and a photosensitive liquid droplet III are positioned in the channel of the valve body; the photosensitive liquid droplet I is positioned under the air outlet I; the photosensitive liquid droplet II is positioned right above the air inlet; the photosensitive liquid droplet III is positioned under the air outlet II; an optical driving group I controlled by a same switch is positioned on the two sides of the air outlet I; an optical driving group II controlled by a same switch is positioned on the two sides of the air outlet II; an optical driving group III controlled by a same switch is positioned on the two sides of the air inlet; an optical driver I is positioned under the photosensitive liquid droplet I; and an optical driver II is positioned under the photosensitive liquid droplet III. The liquid control micro reversing valve device based on optical driving and the using method thereof solve the problems that during the reversing process, the control precision is low, the dynamic response characteristic is poor and the flow efficiency is low.
