Adjustable water flow control apparatus for showers

摘要

The present invention is an adjustable water flow control apparatus for showers which includes an outer housing, an outer inlet member, an outer valve, an inner housing, an inner inlet member, an inner valve, an outlet, an actuating means and a biasing means. The actuating means is configured to axially move the inner housing together with the inner inlet member between a decreased flow position and an increased flow position for water flow control.

1. An adjustable water flow control apparatus for showers comprising:
an outer housing which receives and surrounds a guiding sleeve therein; an outer inlet member securely engaged with a first end of the outer housing; an outer valve securely received within the outer inlet member for controlling water flow into the outer housing; an inner housing disposed with a guiding means on an exterior surface thereof, wherein the guiding means cooperates with the guiding sleeve for axial movement of the inner housing along and within the outer housing; an inner inlet member securely engaged with a first end of the inner housing and having a tapered end which cooperates with a tapered end of the guiding sleeve; the inner inlet member is in water communication with the outer inlet member; an inner valve securely received within the inner inlet member for controlling water flow into the inner housing; the inner valve has a smaller flow rate than the outer valve; the inner housing defines a first water pathway which is in water communication with an outlet at a second end of the outer housing; area between the guiding sleeve and the inner housing defines a second water pathway which is in water communication with the outlet; and an actuating means configured to axially move the inner housing together with the inner inlet member between a decreased flow position and an increased flow position; at the decreased flow position, the tapered end of the inner inlet member engages with the tapered end of the guiding sleeve in a water sealed manner so that water from the outer inlet member is blocked from flowing through an intersection between the inner inlet member and the guiding sleeve to enter the second water pathway and only flows through the inner inlet member to enter the first water pathway; at the increased flow position, the tapered end of the inner inlet member disengages from the tapered end of the guiding sleeve so that water from the inner inlet member flows through the inner inlet member to enter the first water pathway and flows through the intersection between the inner inlet member and the guiding sleeve to enter the second water pathway.
