Sterile water-making device for seedling culture nutrient solution

The invention provides a sterile water-making device for a seedling culture nutrient solution. The sterile water-making device includes a machine casing. The machine casing is internally divided intoa water purification bin, a filtering bin and a condensation bin from top to bottom. An air filtering assembly, a condenser, a primary filtering device and a discharging tank which are communicated sequentially are mounted in the condensation bin. A water suction pump for drawing water from the discharging tank and a filtering system communicated with the water suction pump are mounted in the filtering bin. A water storage tank, a water purification filtering device and a water outlet buffer tank are mounted in the water purification bin, wherein the water storage tank is communicated with thefiltering system, the water outlet buffer tank is provided with a tap, and water in the water storage tank sequentially passes the water purification filtering device, the water outlet buffer tank and the tap and then is disc
