The invention discloses an intelligent unmanned boiling vending machine. The vending machine structurally comprises an adjusting panel, a boiling frame plate, a lining inductor, an external thermal insulation casing, a pedestal, a convenient knob and a heat insulated pad. A slide head can be introduced by an internal draining wire plate when water is overflown during boiling after addition of rawmaterials, an internal circuit is stimulated to push out a push arm, the push arm is pushed out by push columns and triangular blocking sheets, and the four triangular blocking sheets can cover the whole boiling frame plate, boiling water tends not to overflow or spray out. and a consumer is avoided from hidden safety hazards during shopping; and when food is taken out and the water level is reduced, the pressure intensity of water is reduced, a water compressed tablet is pressed in by a spring and extrudes the internal space to reduce the volume, the water level is increased again, and afteraddition of water, the water compressed tablet is drawn back to position of an opposite side rope, and if too much water is added, the spring is compressed in the opposite direction, the water compressed tablet moves rightwards to slightly increase the volume of the device, and water overflow is further prevented.
