One-way valve having vacuum breaking and flow-guiding functions

Abstract

A one-way valve having vacuum breaking and flow-guiding functions is disclosed. It mainly includes a water supplier, a circular wing, and a one-way valve. The water supplier has at least one first inlet, an outlet and a vacuum valve. The outlet is disposed on said water supplier and extending to an interior of a vacuum valve. The vacuum valve connects with a water guiding element. The vacuum valve has a receiving space and a vacuum hole communicating with the receiving space. This circular wing has a channel, a circular flange and a pivoting element. The circular wing is disposed in the receiving space. The circular flange is mounted on the circular wing and extending outward and disposed in the receiving space. A gap is disposed between one end of the circular flange and an inner wall of the receiving space; and a pivoting portion for pivoting with said one-way valve. This one-way valve is rotatable so as to open or close said channel approximately within 90 degrees.

1 . A one-way valve having vacuum breaking and flow-guiding functions comprising: 
 a water supplier having at least one first inlet, an outlet and a vacuum valve; said first inlet being disposed on said water supplier to provide water from said outlet; said outlet being disposed on said water supplier and extending to an interior of a vacuum valve; said vacuum valve having two ends, one end of said vacuum valve allowing said water supplier protruding, the other end of said vacuum valve connecting with a water guiding element; said vacuum valve having a receiving space and a vacuum hole communicating with said receiving space;    a circular wing having a channel, a circular flange and a pivoting element; said circular wing being disposed in said receiving space of said vacuum valve, said channel communicating with said outlet, said circular flange mounted on said circular wing and extending outward from said channel and disposed between said water guiding element and said receiving space, a gap being disposed between one end of said circular flange and a wall of said receiving space; and a pivoting portion for pivoting with said one-way valve;    said one-way valve being facing said channel of said circular wing, said one-way valve being pivotable so as to open or close said channel.    
   
   
       2 . The one-way valve having vacuum breaking and flow-guiding functions as claimed in  claim 1 , further comprising: 
 a second inlet, said first inlet, said second inlet and said outlet being connected.    
   
   
       3 . The one-way valve having vacuum breaking and flow-guiding functions as claimed in  claim 1 , wherein said water guiding element is a hose.  
   
   
       4 . The one-way valve having vacuum breaking and flow-guiding functions as claimed in  claim 1 , wherein said one-way valve having a rotating angle substantially less than 90 degrees.
