Abstract
A pre-washing device for water circulating tubes of a massaging bath tub includes a cap member for a water circulating tube head, a rotary adjustment block locked with the cap member and formed with opposing wedge-shaped openings, and an inner seat located at the water circulating tube head and having channels for the adjustment block to rotate to two stages. A partitioning plate is disposed in the inner seat and includes wedge-shaped openings corresponding to those of the adjustment block. The adjustment block rotates relative to the inner seat so as to align or offset to control the flow of water from the bath tub into the cap member. A valve body and an independent tube are disposed in the water circulating tube head. The valve body is controlled in cooperation with the opening and closing of the water circulating tube head. That is, when the water circulating tube is closed, the valve body is opened, permitting the water to flow from the independent tube into the water circulating tube for pre-washing.
