CHECK VALVE FOR SHOWER NOZZLE AND SHOWER NOZZLE WITH CHECK VALVE
Document Type and Number:
Japanese Patent JP3950929
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a highly durable shower nozzle with a check valve, capable of forming a air-mixed jet with a large quantity of air by sucking a large quantity of outside air with very small resistance of sucked air without generating vibration or noise.
SOLUTION: A spray part is disposed in one end and a water supply part is disposed in the other end of a tubular body with a water channel inside in the shower nozzle. The negative pressure is formed inside the tubular body with the water current fed from the water supply part to the tubular body, and the outside air is sucked through an intake with the negative pressure to form the air mixed jet inside the tubular body. The shower nozzle is for spraying the air mixed jet from the spray part, and has the check valve in the intake part. The check valve comprises a movable valve element and a valve seat on which the valve element is seated for closing the intake, and is structured to press the valve element by a pressure energizing means in the direction of opening the valve.
