PROBLEM TO BE SOLVED: To easily attach drain equipment to a shower hose and to automatically discharge remaining water in the hose after usage by arranging a mobile valve inside a main body to be movable forward/backward through the use of a spring force. SOLUTION: A cylindrical tubular body having a hose end insertion groove 11a and a crew thread 11b at both ends is formed, a front jaw 11d, a rear jaw 11e and a sliding part 11f are arranged on its inner surface and a drain hole 11c is disposed at its lower end to constitute the main body 11. The mobile valve 13 is disposed inside the main body 11 so as to be movable forward/ backward by the intervention of a spring 14 between a flange 13a and the rear jaw 11e of the main body 11 to constitute drain equipment 10. When water pressure is added to the equipment 10 which is connected to the shower hose 9b, the mobile valve 13 is moved to right against the spring 14, the drain hole 11c is clogged and shower water is injected. When the pressure is eliminated, the valve 13 is moved to left by the force of the spring 14, the hole 11c is opened and remaining water is discharged. Thus, remaining water in the hose 9 is automatically discharged. |
