Detailed ways

Please refer to FIG. 1 to FIG. 7 , a two-way flow water saving device includes a body 10 , a cover 20 and an elastic ring 30 . The body 10 has a peripheral wall 11, a bottom wall 12 fixed to the first port of the peripheral wall 11, and a center column 13 fixed to the center of the end face of the bottom wall 12 facing the second port of the peripheral wall 11. The bottom wall 12 is provided with multiple A first water hole 14 arranged around the central column 13. The cover 20 is mounted on the second port of the peripheral wall 11 and connected to the central column 13 , and has a plurality of second water holes 21 arranged around the central column 13 . The elastic ring 30 is adapted to slide and fit outside the center column 13, and can selectively abut against the bottom wall 12 or the cover 20 under the action of forward and reverse water flow to selectively cooperate with the first water hole 14 or the second water hole. 21 to achieve water conservation. Preferably, the port area of the first water hole 14 and the port area of the second water hole 21 are not equal, so that the forward installation and reverse installation have different flow rates and different water-saving effects, and the selected water-saving effect can be selected according to needs. Installation method is required. The elastic ring 30 is preferably an O-RING elastic ring, but it is not limited thereto, and other elastic members can also be used as required.

In a preferred solution, the bottom of the peripheral wall 11 can also protrude from the bottom of the inner turning surface with a plurality of circumferentially spaced protrusions 15, the bottom surface of the protrusions 15 and the end surface of the bottom wall 12 facing the second port of the peripheral wall 11 flush. When the elastic ring 30 abuts against the bottom wall 12, it can cooperate with the protrusion 15 to control and form a small flow rate. In this way, through the cooperation of the elastic ring 30 and the protrusion 15 of the sliding sleeve with the first water hole 14 and the second water hole 21 of different port areas, when the two-way flow water saving device of the present invention is forward or reverse When installed in the water outlet terminal, the conversion effect between the smaller flow and the larger flow can be realized, which is particularly outstanding.

In this embodiment, the connection method between the body 10 and the cover 20 is, for example, as follows: the second port of the peripheral wall 11 is provided with an annular slot 111, and the peripheral edge of the cover 20 fits into the annular slot 111; An insertion hole 131 is recessed on the end surface of the central column 13 , and an insertion column 22 is protruded on the end surface of the cover portion 20 , and the insertion column 22 is adapted to be inserted into the insertion hole 131 .

Preferably, the opposite end surfaces of the cover 20 and the bottom wall 12 are protrudingly provided with a boss 40, which is beneficial to dismantle the utility model from the water outlet terminal by clamping it with a tool.

In this embodiment, the outer rotating surface of the peripheral wall 11 is a cylindrical surface and is recessed with an annular installation groove 112, and an elastic sealing ring 60 is installed in the annular installation groove 112, and the elastic sealing ring 60 can be an O-RING elastic ring , but not limited thereto, other elastic materials can also be used as required. The elastic sealing ring 60 at least partially protrudes out of the cylindrical surface in a free state.
