WATER-CONSERVING URINAL VALVE USING A SHAPE-MEMORY ALLOY AND A WATER-CONSERVING URINAL VALVE USING A SHAPE-MEMORY ALLOY CAPABLE OF ONE-TOUCH FORCED OPENING

摘要

Disclosed are a water-conserving urinal valve using a shape-memory alloy and a water-conserving urinal valve using a shape-memory alloy which is capable of one-touch forced opening. The water-conserving urinal valve using a shape-memory alloy and the water-conserving urinal valve using a shape-memory alloy capable of one-touch forced opening comprise: an upper stopper formed with through holes allowing urine to flow in; an outer structure for collecting urine; a valve stopper separated from the outer structure such that urine is discharged; a biasing spring which is interposed between the upper stopper and the valve stopper and imparts a resilient force to the valve stopper so as to prevent the smell of urine and odours in the drain from flowing back; and a shape-memory alloy spring which is inserted inside the biasing spring and imparts a resilient force, towards the lower side of the outer structure, to the valve stopper such that the valve stopper is opened by urine; and, here, the outer structure and the upper stopper are screwed together such that the valve stopper opens by moving downwards. The above arrangement can prevent odours such as the smell of urine since the valve is normally blocked off by means of the exterior biasing spring using a double spring structure.
