In order to be able to control to ensure this effect, the water duct 13 is provided with a regulator 15, and the regulator 15 is able to regulate the water flow of the water duct 13.
Because the water delivery speed is low, the aperture of the water flow is small, and the effect of the conventional regulator is difficult to achieve. The adjuster 15 of the present invention is preferably as shown in fig. 5 and 6, the adjuster 15 including an adjuster shaft 151, an adjusting sleeve 152, a ball spring 154, and two adjuster end caps 153; the adjusting sleeve 152 is sleeved on the adjuster shaft 151, the adjusting sleeve 152 is provided with a plurality of third water conveying holes 1521 which are axially arranged, and the third water conveying holes 1521 are uniformly distributed on the circumference and have different diameters; the two regulator end covers 153 are respectively connected to two ends of the regulator shaft 151 and are in fit sealing with two ends of the regulating sleeve 152, and a fourth water delivery hole 1531 is formed in each regulator end cover 153; the regulator shaft 151 is provided with positioning taper holes 1511 with the same number as the third water delivery holes 1521, and the positioning taper holes 1511 are uniformly distributed on the circumference; the ball spring 154 is connected with the adjusting sleeve 152, the ball of the ball spring 154 can be embedded into the positioning taper hole 1511 to realize the positioning of the adjusting sleeve 152, and when the ball is embedded into the positioning taper hole 1511, the third water delivery hole 1521 corresponds to the fourth water delivery hole 1531 in position; the water pipe 13 is connected to the regulator end cap 153 and communicates with the fourth water delivery hole 1531.
The handheld regulator end cap 153 rotates the regulating sleeve 152 to align the third water delivery hole 1521 with different diameters with the fourth water delivery hole 1531, so that water flows through the third water delivery hole 1521, and the water flow is different when the diameters of the third water delivery hole 1521 are different, thereby realizing the water flow speed regulation.
The regulator end cap 153 may be coupled to the regulator shaft 151 in a manner as shown in fig. 5, with one regulator end cap 153 being formed integrally with the regulator shaft 151; one end of the adjuster shaft 151 is provided with a square positioning hole, and the other adjuster end cover 153 is provided with a square positioning shaft which is inserted into the square positioning hole, so that the adjuster end cover 153 and the adjuster shaft 151 are prevented from rotating relatively; the fastener compresses the adjuster end cap 153 against the adjuster shaft 151.
