As shown in fig. 6: the outer surface of the side hole is covered with an elastic film 8, the elastic film 8 is positioned right above the side hole 3, the width of the elastic film 8 is half of that of the side hole, the side hole 3 is divided into two uniform small holes by the elastic film 8, and the two small holes are semicircular. When the pressure-adjustable water-saving device is used, the elastic film 8 can be changed into different shapes under different fluid pressures, when the pressure is small, the water outlet area of the semicircular small hole is small, but when the pressure is increased, the water outlet area of the semicircular small hole is also increased, and the maximum adjustment benefit is that: in the case of manual work, the thrust of the hand cannot be kept substantially constant, by the action of the adjustment of the elastic membrane 8, so that the fluid is ejected at substantially the same speed. In order to make better use of the adjustment effect of the elastic membrane 8, the side hole 3 is made in an elliptical shape, which makes it easier to adjust the size of the two holes.
The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related fields are also included in the scope of the present invention.
