Claim 14:
15. The filtration and purification processing method according to claim 1, wherein both the inlet valve and the outlet valve are valve units, the valve unit comprises a valve conductive layer, a valve substrate layer, and a flexible membrane, wherein the valve conductive layer is made of a charged piezoelectric material, electrically connecting to a microprocessor to be controlled by the microprocessor to deform, wherein an accommodating space is maintained between the valve conductive layer and the valve substrate layer, wherein the flexible membrane is made of a flexible material and attached on a side of the valve conductive layer so as to be placed in the accommodating space, wherein a plurality of holes are respectively formed on the valve conductive layer, the valve substrate layer, and the flexible membrane, the holes of the valve conductive layer and the holes of the flexible membrane are aligned with each other, and the holes of the valve substrate layer and the holes of the valve conductive layer are not aligned with each other, wherein when the valve conductive layer is not controlled by the microprocessor, the valve conductive layer is retained in the accommodating space and spaces apart from the valve substrate layer, thereby allowing the valve unit to be in an opened state since the holes of the valve substrate layer and the holes of the valve conductive layer are aligned with each other, wherein when the valve conductive layer is controlled by the microprocessor to deform, the valve conductive layer is moved close to and attach to the valve substrate layer, so that the flexible membrane covers the holes of the valve substrate layer, thereby allowing the valve unit to be in a closed state since the holes of the flexible membrane and the holes of the valve substrate layer are aligned with each other.
