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 sliding member slidably coupled with the faucet head to enable a user to operate the control valve within the water valve by operating the sliding member from a side of the faucet head.

First claim

What is claimed is:

1. A faucet comprising:
a faucet base having a first and second end, the faucet base being configured to be mounted to support the faucet near the first end and to regulate water flow through the faucet;
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 configured 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 configured 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;
an aerator within the chamber and located between the first end and the second end of the chamber, the aerator 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 air inlet being coupled with the chamber, and
a control valve movable within the aerator between a first position and a second position, the first position enabling mixing air from the 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 a water flow from the first end of the chamber to the second end of the chamber, the control valve using a water pressure supplied by the water hose to facilitate an operation of the control valve;

a sliding member movably coupled with the faucet head at a side of the faucet head, the sliding member being configured to enable the operation of the control valve within the aerator by being slid from the side of the faucet head in a direction substantially parallel to the direction of the water flow from the first end of the chamber to the second end of the chamber, the sliding of the sliding member causing the control valve to move between the first position and the second position; and
a switch valve near the second end of the chamber to switch a flow of the water-and-air mixture between a stream discharge and a spray discharge.

2. The faucet of claim 1 , wherein the chamber is an opening provided within the faucet head, and the faucet head provides the chamber therein through one of a uni-body construction or a multiple-part construction.

3. The faucet of claim 1 , wherein the sliding member comprises a first surface and a second surface mechanically coupled with the first surface, the first surface being configured for user operation in a direction substantially parallel to a side surface of the faucet head.

4. The faucet of claim 3 , wherein the second surface is configured to engage with the control valve to move the control valve from the second position to the first position when the first surface is slid in a direction substantially opposite to the direction of the water flow from the first end of the chamber to the second end of the chamber, the second surface is configured to engage with the control valve to restore the control valve from the first positon to the second position by moving the control valve from the first position to the second position when the first surface is slid again in the direction substantially opposite to the direction of the water flow from the first end of the chamber to the second end of the chamber, and at least one of the sliding member and the control valve is coupled to a spring that returns the sliding member to an initial position when the sliding member is not being operated.

5. The faucet of claim 1 , wherein the sliding member is operated 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 sliding member is further operated to cause the control valve to move from the first position to the second position.

6. The faucet of claim 1 , wherein the chamber includes at least one air inlet at or near a side of the faucet head or the second end of the chamber, the at least one air inlet of the chamber is in communication with the at least one air inlet of the aerator to enable the aerator's mixing of water and air.

7. The faucet of claim 1 , wherein the aerator contains a screen coupled with the control valve and located downstream of the control valve, the screen having a plurality of water passageways and being in communication with the at least one air inlet of the aerator to enable the aerator's mixing of water and air.

8. The faucet of claim 1 , wherein the faucet base further comprises a water flow control coupled with the water hose, a cold water intake, and a hot water intake to vary, when a water flow is enabled, a mix of cold water and hot water going into the water hose.

9. The faucet of claim 1 , wherein the chamber includes a cavity between the first end and the second end of the chamber for receiving the aerator, and the aerator is a pre-assembled assembly with the control valve inside the aerator and with a driving member protruding through one end of the aerator and coupled with the control valve to cause the control valve to move between the first and the second position.

10. The faucet of claim 1 , wherein the outlet comprises a water outlet, the water outlet comprises a center outlet and a plurality of peripheral outlets, and the second end of the chamber provides a stream discharge of the mixture of water and air through the center outlet of the water outlet and a spray discharge of the mixture of water and air through the plurality of peripheral outlets of the water outlet.

11. A faucet comprising:
a faucet base having a first and second end;
a water hose extending within the faucet base and being movable through the second end of the faucet base;
a faucet head having a first end, a second end, a chamber between the first and second end of the faucet head and coupled with the water hose, and an outlet coupled with the chamber at or near the second end of the faucet head to discharge a mixture of water-and-air flow, the first end of the faucet head being configured to be coupled to the second end of the faucet base while remaining coupled to the water hose and to be dismountable from the second end of the faucet base while remaining coupled to the water hose;
an aerator within the chamber, the aerator comprising:
one or more air inlets and a water inlet to enable mixing air from the one or more air inlets with water from the water inlet, the water inlet coupled with the water hose, the one or more air inlets being coupled with the chamber, and
a control valve movable within the aerator between a first position and a second position, the first position enabling mixing air from the 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, the control valve being configured to move between the first position and the second position in a direction substantially parallel t
