Abstract
A water saving device is disclosed, which comprises a base having a water flow channel, a throttle ring and a support seat made of an elastic material, and a capacity space is formed in the base, and the support seat is disposed in the capacity space. An annular channel is formed between the support seat and the base. The water channel is in communication with the annular channel. The throttle ring is disposed in the annular channel. When the water pressure is increased to a certain extent, the throttle ring is deformed, and the cross-sectional area of the water flow channel is reduced. The water saving device can effectively prevent the throttle ring from shifting or falling off, and it also has good structural strength and stability that is not easily deformed or broken by external force.
