Abstract

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a push-to-rotate member movably coupled with the faucet head to enable operating the control valve within the water valve by operating the push member from or near a side of the faucet head.

First claim

What is claimed is:

1. A faucet comprising:
a faucet base having a first end and a second end, the faucet base being adapted to be mounted to support the faucet near the first end and to regulate a water flow;
a water hose coupled with the faucet base by extending through the first end and second end of the faucet base, the water hose being adapted to be flexible and movable through an opening in the first end and through an opening in the second end;
a faucet head movably coupled to the second end of the faucet base, the faucet head being adapted to be dismountable from the second end of the faucet base while remaining coupled to the water hose to direct a mixture of water-and-air flow to a location away from the faucet base and to be relocated back to the second end the faucet base to discharge the mixture of water-and-air flow while being coupled to the faucet base;
a chamber within the faucet head having a first end and a second end, the first end of the chamber being coupled with the water hose and being coupled, in a dismountable manner, to the second end of the faucet base, the second end of the chamber providing an outlet to discharge the mixture of water-and-air flow;
a water valve within the chamber between the first end and the second end of the chamber, the water valve comprising:
at least one air inlet and a water inlet to enable mixing air from the at least one air inlet with water from the water inlet, the water inlet being coupled with the water hose, the at least one air inlet being coupled with the chamber, and
a control valve movable within the water valve between a first position and a second position, the first position enabling mixing air from the at least one air inlet with water from the water inlet to provide the mixture of water-and-air flow, and the second position enabling shut-off of the mixture of water-and-air flow, a direction of the control valve's movement between the first position and the second position being substantially parallel to a direction of the water flow from the first end of the chamber to the second end of the chamber, the control valve using a water pressure from the water supplied by the water hose to facilitate an operation of the control valve; and

a push member movably coupled with the faucet head and comprising a plunger and a rotating device movably coupled to the plunger and the control valve, the push member being adapted to enable an operation of the control valve within the water valve by pressing the plunger from a side of the faucet head to cause the rotating device to rotate between a first angular position and a second angular position relative to the plunger, a rotation of the rotating device between the first and second angular positions causing the control valve to move between the first position and the second position, wherein
the plunger is pressed to cause the control valve to move from the second position to the first position, and the control valve remains in the first position until the plunger is further pressed to cause the control valve to move from the first position to the second position.

2. The faucet of claim 1 , wherein the plunger is adapted for user operation in a direction substantially perpendicular to a side surface of the faucet head, the rotating device being adapted to engage with the control valve so that the rotating device rotating to a different angular position from a current angular position causes the control valve to move between the second position and the first position every time the plunger is pressed and released.

3. The faucet of claim 2 , wherein the push member comprises a spring that urges against the plunger when the plunger is being pressed.

4. A faucet comprising:
a faucet base having a first end and a second end, the faucet base being adapted to be mounted to support the faucet near the first end and to regulate a water flow;
a water hose coupled with the faucet base by extending through the first end and second end of the faucet base, the water hose being adapted to be flexible and movable through an opening in the first end and through an opening in the second end;
a faucet head movably coupled to the second end of the faucet base, the faucet head being adapted to be dismountable from the second end of the faucet base while remaining coupled to the water hose to direct a mixture of water-and-air flow to a location away from the faucet base and to be relocated back to the second end the faucet base to discharge the mixture of water-and-air flow while being coupled to the faucet base;
a chamber within the faucet head having a first end and a second end, the first end of the chamber being coupled with the water hose and being coupled, in a dismountable manner, to the second end of the faucet base, the second end of the chamber providing an outlet to discharge the mixture of water-and-air flow;
a water valve within the chamber between the first end and the second end of the chamber, the water valve comprising:
at least one air inlet and a water inlet to enable mixing air from the at least one air inlet with water from the water inlet, the water inlet being coupled with the water hose, the at least one air inlet being coupled with the chamber, and
a control valve movable within the water valve between a first position and a second position, the first position enabling mixing air from the at least one air inlet with water from the water inlet to provide the mixture of water-and-air flow, and the second position enabling shut-off of the mixture of water-and-air flow, a direction of the control valve's movement between the first position and the second position being substantially parallel to a direction of the water flow from the first end of the chamber to the second end of the chamber, the control valve using a water pressure from the water supplied by the water hose to facilitate an operation of the control valve; and

a push member movably coupled with the faucet head and comprising a plunger and a rotating device movably coupled to the plunger and the control valve, the push member being adapted to enable an operation of the control valve within the water valve by pressing the plunger from a side of the faucet head to cause the rotating device to rotate between a first angular position and a second angular position relative to the plunger, a rotation of the rotating device between the first and second angular positions causing the control valve to move between the first position and the second position, wherein the push member further comprises a seat and a spring, the plunger and the rotating device being adapted to be slidably coupled to the seat, the spring being adapted to be coupled to the rotating device to urge the rotating device towards the plunger, the plunger being adapted to drive the rotating device, while the plunger is being pressed, in a direction away from the seat and cause the rotation device to rotate upon the urging of the spring.

5. A faucet comprising:
a faucet base having a first end and a second end, the faucet base being adapted to be mounted to support the faucet near the first end and to regulate a water flow;
a water hose coupled with the faucet base by extending through the first end and second end of the faucet base, the water hose being adapted to be flexible and movable through an opening in the first end and through an opening in the second end;
a faucet head movably coupled to the second end of the faucet base, the faucet head being adapted to be dismountable from the second end of the faucet base while remaining coupled to the water hose to direct a mixture of water-and-air flow to a location away from the faucet base and to be relocated back to the second end the faucet base to discharge the mixture of water-and-air flow while being coupled to the faucet base;
