1. Field of the Invention
The present invention relates to an improved water-saving device structure, in particular relates to an improved water-saving device structure applied in a water-conservation device in the related technical field.
2. Description of the Related Art
In conventional water-saving devices, the main part of them lies in the structure of foaming head. The foaming head includes a water-guiding seat body utilized to be connectively disposed on a water-outflow opening of a faucet, a water-entry sheet body accommodated in the water-guiding seat body, and a net cover body accommodated in the water-guiding seat body (not shown in FIGs.). When the water-guiding seat body is connectively disposed on the water-outflow opening of the faucet, an outflow water from the faucet entering into the foaming head through the water-entry sheet body is mixed with air or bubbles blended by the net cover body, thereby increasing the flow rate of the bubbles in the water to reduce the volume of the outflow water per unit from the faucet and to slow down the flow rate of the outflow water for obtaining a water-saving effect. However, due to the inconsistent flow rate and pressure of the outflow water whenever the faucet is opened, the outflow water from the faucet cannot be effectively regulated by the water-entry sheet body and the net cover body disposed in the water-guiding seat body, and thus the outflow water from the foaming head is unstable. Moreover, because the faucet cannot regulate the flow rate of the outflow water at different water pressures, the flow rate of the outflow water from the faucet is not uniform and the time of the outflow water in use is extended, and thus the water-saving effect is not perfect.
In view of this, the purpose of the present invent is to provide an improved water-saving device structure to increase the outflow water stability and the water-saving effect.
The improved water-saving device structure of the present invention comprises a water-outflow seat body, a water-barrier sheet body and a water-entry cover body. The water-outflow seat body comprises an outer seat circular wall portion, a water-outflow middle seat portion, a plurality of stopping wall portions disposed between the outer seat circular wall portion and the water-outflow middle seat portion, a water-storage circular slot portion disposed between the stopping wall portions and the water-outflow middle seat portion, a position-limiting clamping portion disposed inside the outer seat circular wall portion, a seat top surface disposed on top of the water-outflow middle seat portion, a plurality of water-inflow openings recessed on top of the seat top surface, and a water-outflow opening centrally penetrated through the water-outflow middle seat portion. The water-barrier sheet body, fixedly clamped in between the water-outflow middle seat portion and the stopping wall portions of the water-outflow seat body, comprises a centrally-disposed water-conducting opening corresponding to the water-outflow opening of the water-outflow seat body, an elastic stopping portion outwardly extended from a peripheral ring of the water-conducting opening, and a fixed ring disposed on an outermost ring of the elastic stopping portion. The water-entry cover body, covered on the water-outflow seat body, comprises a centrally-disposed water-entry opening corresponding to the water-conducting opening of the water-barrier sheet body and a lower peripherally-disposed compression ring compressively engaged in between the position-limiting clamping portion and the outer seat circular wall portion of the water-outflow seat body. A water-storage room is disposed in the compression ring of the water-entry cover body. When the water-entry opening of the water-entry cover body is relatively disposed on the water-outflow opening of the faucet or the shower head, the high pressure entry water downwardly presses the water-barrier sheet body to cause the downwardly-moved elastic stopping portion thereof to block the water-inflow openings of the water-outflow seat body, so that the water flow is conducted to the water-outflow opening of the water-outflow seat body through the water-conducting opening of the water-barrier sheet body; moreover, the low pressure entry water is conducted to the water-outflow opening of the water-outflow seat body via one path traveling from the water-conducting opening of the water-barrier sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of the stopping wall portions of the water-outflow seat body, the water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained no matter what the high or low pressure entry water is supplied, and also the water-saving effect and the outflow water with steady flow rate can be obtained.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The present invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:

In summary, the present invention provides the following advantages. Firstly, the outflow water with steady flow rate can be obtained no matter what the high or low pressure entry water is supplied. That is, when the water-entry opening of the water-entry cover body is relatively disposed on the water-outflow opening of the faucet or the shower head, the high pressure entry water downwardly presses the water-barrier sheet body to cause the downwardly-moved elastic stopping portion thereof to block the water-inflow openings of the water-outflow seat body, so that the water flow is conducted to the water-outflow opening of the water-outflow seat body through the water-conducting opening of the water-barrier sheet body; moreover, the low pressure entry water is conducted to the water-outflow opening of the water-outflow seat body via one path traveling from the water-conducting opening of the water-barrier sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of the stopping wall portions of the water-outflow seat body, the water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Secondly, the outflow water with constant flow rate can be obtained no matter what the high or low pressure entry water is supplied, and the waste of the water is decreased by reducing the water pressure variation, thus to obtain water-saving effect.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
