<p>PURPOSE:To control the water spraying amount and the water spraying pressure by one person by connecting a water spray nozzle and a pumper through a circuit built-in type hose, and exchanging massages with the pumper side through a liaison device connected to the base of the spray nozzle through tip adaptors. CONSTITUTION:A spray nozzle 1 and a pumper are connected through a circuit built-in type hose which is a hose with built-in cable, and the cable in the circuit built-in type hose is drawn out through tip adaptors 4 and 5 between the spray nozzle 1 and the circuit built-in type hose. To the cable, is connected a liaison device 54 to exchange massages with the pumper side and/or to control the water supply control unit. As a result, the water spray amount and the water spray pressure can be controlled by a single water spray handler easily.</p> |
