Description

FIELD OF THE INVENTION

The present invention relates a water faucet with function of noise reduction and pressure adjustment, and more particularly, to a water faucet having function of noise reduction and pressure adjustment that prevents the resonance in a pipeline occurred due to the vibration of water flowing therein.

BACKGROUND OF INVENTION

With the progress of the technology, people develop more water sources and better water storage methods, i.e., such as well digging and dam constructing in response to the requests of life living needed. Nowadays, a water storage place is allocated in a higher location for supplying water to a house as a water supplying scheme with convenience, in which a pipeline is used for transporting water. As water is supplied to the house, people can regulate water flow by opening or closing a water faucet installed in the house. With the trend of energy saving, many water faucets used at home have been manufactured with a function of water adjustment.
A conventional water adjusting device can be found in a Taiwan patent No. 026242 , entitled as "Integrated ball valve water faucet", generally comprising a ball valve, a flow control lever, a stable block, a leak proof ring, a reinforcement ring, and an integrated shell as a cover for covering these elements. The ball valve has an opening and is linked with the flow control lever so that the ball valve can be rotating while the flow control lever is manipulated. The fluid is flowing out from the tube opening when the ball valve opening is in a position facing toward the tube opening, and the fluid is stopped when the lateral side without the opening of the ball valve is in a position facing toward the tube opening. Thus, the flow control lever and the ball valve are operated for opening, closing, and adjusting the water flow.
However, although the conventional ball valve has the functions of opening, closing and adjusting the water flow, it is found that the vibration of water flow will generate vigorous resonance in the pipeline and it will result a noise not only annoying a user, but also leading to hearing impairment. Because of these drawbacks, the water faucet needs to be further improved.

The present invention further comprises an outflowing element (2) connecting between the adjusting element (1) and a outflowing unit (3), wherein the outflowing element (2) is connected with one end, whose inner diameter of the flowing channel (111) is smaller than the inner diameter of the other end, of the adjusting element (1).
In the present invention, the noise caused by resonance in the pipeline can be reduced by providing a gradually reducing width of flowing channel (111) and enabling the water valve (12) to regulate the water amount that flows through the outflowing element (2).
The above is a main embodiment of the present invention that is embodied with the essential technical features as defined in claim 1. The other claims that depend on claim 1 define other added technical features. These claims should not be deemed as a limitation of claim 1.
Please further refer to FIG. 5. For efficiently use the water valve (12) to regulate water amount flowing through the outflowing element (2), the water valve (12) is formed with a water valve channel (121) that flows through the water valve (12). On a side of the water valve (12) is formed with a position-controlling notch (122) for turning a direction of the water valve (12) to either a position that the water valve channel (121) is connected with the flowing channel (111) or a position that the water valve channel (121) blocks the communication with the flowing channel (111). A fastening ring (123) is for fastening the water valve (12) on a side opposite to the side that the position-controlling notch (122) is provided, and the outflowing element (2) has a controlling unit (21) for opening, closing and adjusting the water flow. In a preferred embodiment, to prevent from being touched or moved by children, the position-controlling notch (122) is preferably placed at bottom side of water valve (12). In addition, for ensuring that water valve (12) will not get loosed with the guiding pipe (11) while the water valve (12) is turned, the water valve (12) is provided with a fastening ring (123) fastened on the side opposite to the side that the position-controlling notch (122) is formed.
