Abstract:
A faucet aerator having a constant stream valve plate, comprising a casing (1), the casing being provided therein with an aerator (2), and a constant stream valve plate (3) being provided in the casing (1) and being located at a position above the aerator (2); the constant stream valve plate (3) comprises an upper stream limiting plate (41) and a lower stream limiting plate (42), the upper stream limiting plate (41) being an elastic component that may be deformed and displaced under the action of water pressure, and the upper stream limiting plate (41) being provided thereon with a water outlet hole (43); the lower stream limiting plate (42) is provided thereon with a water discharge port (44) and a conical column (45), the conical column (45) vertically corresponding to the position of the water outlet hole (43) on the upper stream limiting plate (41); the upper stream limiting plate (41) is deformed under the action of water pressure to drive the water outlet hole (43) to move towards the conical column (45), the conical column (45) partially or completely blocking the water outlet hole (43). Thus, a reasonable amount of water may be obtained whether in a high water pressure or low water pressure state, thereby reducing unnecessary waste.
