WATTER SUPPLIER HOSE MANUFACTURING METHOD FOR A SPROUT GROWING DEVICE

摘要

PURPOSE: A producing method of a water supply hose of a vegetable growing apparatus is provided to improve the lifetime of the water supply hose by heat-molding the hose into a spiral form. CONSTITUTION: A producing method of a water supply hose of a vegetable growing apparatus comprises the following steps: extruding silicon to obtain a silicon hose; winding the silicon hose on a mold(210) with a spiral groove(211); and heat-molding the silicon hose at 150~300deg C for 3~6 hours. The spiral groove has the bottom surface with the smaller curvature then the curvature of the silicon hose.
