Two-Path Water Output Device

Abstract

A two-path water output device includes a valve, and is mounted around by a shell. The valve has a first waterway and a second waterway. The first waterway is constantly connected to a water converter, while the second waterway is controlled to be open or closed by a control valve core. Such two-path structure is simple, novel and easily controllable for two types of water output like tap water and filtered water. When the second waterway is closed, the water pressure switches a water converter connected to the inlet end of the valve to the first waterway to output water. When the second waterway is open, the released pressure switches to the first waterway to output water.

What is claimed is: 
     
         1 . A two-path water output device comprising:
 a valve having:
 a first waterway defined inside the valve; 
 a second waterway defined inside the valve; 
 a control valve core mounted inside the valve to control the second waterway to open or close; and 
   a shell mounted around the valve.   
     
     
         2 . The two-path water output device as claimed in  claim 1 , wherein the valve has:
 an inlet end;   an outlet end;   a first inlet channel and a second inlet channel axially formed in the inlet end;   a first outlet channel and a second outlet channel axially formed in the outlet end;   a trough radially formed inside the valve, and communicating with the first inlet channel, the first outlet channel, the second inlet channel and the second outlet channel;   a first waterway sequentially formed by the first inlet channel, the trough and the first outlet channel and adapted to connect to a water converter;   a second waterway sequentially formed by the second inlet channel, the trough and the second outlet channel; and   a control valve core mounted inside the trough to control the second waterway to open or close.   
     
     
         3 . The two-path water output device as claimed in  claim 1 , wherein the valve has:
 an inlet end;   an outlet end;   a first inlet channel and a second inlet channel axially formed in the inlet end;   a first outlet channel and a second outlet channel axially formed in the outlet end;   a first trough radially formed inside the valve and communicating with the first inlet channel and the first outlet channel;   a second trough radially formed inside the valve and communicating with the second inlet channel and the second outlet channel;   a first waterway sequentially formed by the first inlet channel, the first trough and the first outlet channel, and adapted to connect to a water converter;   a second waterway sequentially formed by the second inlet channel, the second trough and the second outlet channel; and   a control valve core mounted inside the trough to control the second waterway to open or close.   
     
     
         4 . The two-path water output device as claimed in  claim 3 , wherein the first outlet channel includes a first inside outlet channel and a first outside outlet channel that are concentric to each other; and
 a switch valve core mounted inside the first trough, and selectively controls one of the first inside outlet channel and the first outside outlet channel to communicate with the first inlet channel.   
     
     
         5 . The two-path water output device as claimed in  claim 2 , wherein the second inlet channel is formed inside the first inlet channel. 
     
     
         6 . The two-path water output device as claimed in  claim 2 , wherein tap water flows through the first waterway, and filtered water flows through the second waterway.
