## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a water flow controller or controlling device for a faucet assembly, and more particularly to a water flow controlling device for automatically closing or shutting off a faucet device or for shutting off the water when an outer housing or receptacle of the faucet device is removed or disengaged or separated from the water mixing or controlling mechanism of the faucet device.
2. Description of the Prior Art
Typical water flow controlling devices for faucets comprise a control mechanism for automatically controlling a faucet to deliver the water for a predetermined time interval and for flushing or cleaning purposes; or for mixing the cold and hot water to provide a mixed water with a suitable mixing temperature and for preventing the users from being hurt by the hot water.
For example, U.S. Pat. No. 4,147,631 to Deines et al., and U.S. Pat. No. 4,172,796 to Corder disclose two of the typical fluid flow controlling devices including a complicated structure for controlling the faucet to mix or blend the cold and hot water to provide a mixed water with a suitable mixing temperature, and to supply or deliver the water out through an outlet nozzle or outlet port or the like.
However, normally, the typical fluid flow controlling devices for the faucet devices comprise a complicated structure that may not be easily fixed or repaired. For example, the cold and hot water supplied lines from the cold and hot water reservoir to the typical fluid flow controlling devices or to the faucet devices should all be cut off or switched off before the parts or elements of the typical fluid flow controlling devices of the faucet devices may be dismantled or removed or disengaged or separated from each other for fixing or repairing purposes.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional water flow controlling devices for faucets.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a water flow controlling device for a faucet device and for automatically closing or shutting off a faucet device or for shutting off the water when an outer housing or receptacle of the faucet device is removed or disengaged or separated from the water mixing or controlling mechanism of the faucet device.
In accordance with one aspect of the invention, there is provided a water faucet device comprising a controlling mechanism including a bottom wall, a housing disposed on the bottom wall and having a compartment formed in the housing, and a casing disposed on the bottom wall and located beside and adjacent the housing and having a chamber formed in the casing, and having a passage formed and located between the housing and the casing for communicating the chamber of the casing and the compartment of the housing with each other, the casing including a valve seat formed or provided in the casing, a check valve device engaged in the chamber of the casing for engaging with the valve seat of the casing and for blocking and releasing the chamber of the casing and for controlling a water to flow out of the chamber of the casing, two pipes attached to the bottom wall for supplying cold and hot water into the compartment of the housing, a control device engaged in the compartment of the housing for controlling a mixing of the cold and the hot water, a receptacle including an outlet port, and including a chamber formed in the receptacle for receiving and engaging with the housing and the casing and the bottom wall of the controlling mechanism, and including a partition provided in the chamber of the receptacle for forming a space in the receptacle and for separating the space and the chamber of the receptacle from each other, and including a conduit provided in the receptacle and having a bore formed in the conduit and communicating with the chamber and the space of the receptacle, the space of the receptacle being communicating with the outlet port but spaced from the chamber of the receptacle with the partition, and an actuator tube attached to the conduit of the receptacle and including a lower portion extended out of the conduit of the receptacle, and including an actuating protrusion extended from the lower portion of the actuator tube and located within the chamber of the receptacle and engaged into the chamber of the casing and engaged with the check valve device for disengaging the check valve device from the valve seat of the casing and for opening or releasing the chamber of the casing and for allowing the water to flow out through the chamber of the casing and then to flow into the actuator tube, and the check valve device being engaged with the valve seat of the casing for blocking the chamber of the casing when the actuating protrusion of the actuator tube is disengaged from the casing and separated from the check valve device, and thus for allowing the parts or elements of the fluid flow controlling device of the water faucet device may be dismantled or removed or disengaged or separated from each other for fixing or repairing purposes without shutting off or switching off the cold and the hot water supplying pipes that are attached to the bottom wall of the housing.
The receptacle includes a second check valve device disposed and engaged into the conduit of the receptacle for controlling the water to flow through the conduit of the receptacle, and for limiting and guiding the water to flow only from the chamber of the receptacle into the space of the receptacle and then to flow out through the outlet port of the receptacle, and for preventing the water from flowing backward from the space into the chamber of the receptacle.
The controlling mechanism includes a pathway formed in the housing or in the casing, and an actuating mechanism includes a shaft engaged in the pathway of the casing or the housing for engaging with the control device and for controlling the control device to mix the cold and the hot water to the required or predetermined temperature. A knob may further be provided and attached to the shaft for actuating or operating the shaft relative to the housing or the casing.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
