The plant bionic solar still as claimed in claim 1, wherein the desalination process of the device refers to the transpiration of plant leaves, and the specific process is as follows: the sunlight passes through the light-transmitting plate (15), is absorbed by the heat-absorbing plate (17) and is converted into heat energy, and the heat energy is conducted to the seawater in the hydrophilic fiber membrane (18) below; the hydrophilic fiber membrane (18) is used as an evaporation surface, seawater in the hydrophilic fiber membrane starts to evaporate after being heated, generated water vapor passes through the distillation membrane (19), is diffused into the condensation interlayer (20), is condensed by the condensation plate (21), and condensed fresh water flows through the fresh water pipeline (8) under the action of gravity and is finally collected in the fresh water tank (10).
6. The plant bionic solar still according to claim 1, wherein the water delivering and draining mode of the device refers to the water spitting phenomenon of plants, and the specific process is as follows: the seawater is absorbed by the bionic hydrophilic root (1), then is conveyed to a water conveying core (13) in the bionic stem (3), and is conveyed to the bionic veins (5) under the action of water potential difference; through utilizing capillary suction, the sea water in bionical vein (5) permeates through hydrophilic fiber pipe (23), constantly diffuses to hydrophilic fibrous membrane (18) on both sides, make hydrophilic fibrous membrane (18) remain the moist state throughout, the rivers that the salt ion that the while evaporation process produced dissolved in hydrophilic fibrous membrane (18) form concentrated sea water, concentrated sea water droplet (7) are followed the section of stretching out of bionical vein (5) and are dropped downwards, by outside the device of being discharged, the accumulation of salt crystal at the evaporation surface has been avoided.
