Automatic expansion shower head for kitchen sink

Abstract

The present invention provides an automatic telescope shower head set for kitchen sink, which is typically comprised of a main body, a shower head and a restoring spring; wherein said main body has a fitting set upon the top end for connecting to the outlet end of a delivery hose, and a tube set upon the center; said shower head has a shroud tube built upon the top end for containing into the inside of the tube of the main body, cooperating to the delivery hose, the fitting, the tube and the shower head, to construct the water flowing channel, there are a pair of opposite a reversion fin and a crowned collar built upon the inside wall of the tube and the outside wall of the shroud tube respectively so that the both ends of the restoring spring touch against the opposite faces of said inversion fin and said crowned collar, thereby the restoring force of the restoring spring pushing the shroud tube up bringing the shower head to restore the original position, there are sealing loops set upon the contacting surfaces of each pair of adjacent components. The structure makes the volume of the faucet reduce, and prevents the shower head from striking damage, and facilitates to using and storing.

1 . An automatic telescope shower head set for kitchen sink typically comprised of a main body, a shower head and a restoring spring; wherein said main body has a fitting set upon the top end for connecting to the outlet end of a delivery hose, and a tube set upon the center; said shower head has a shroud tube built upon the top end for containing into the inside of the tube of the main body, cooperating to the delivery hose, the fitting, the tube and the shower head, to construct the water flowing channel, there are a pair of opposite a reversion fin and a crowned collar built upon the inside wall of the tube and the outside wall of the shroud tube respectively so that the both ends of the restoring spring touch against the opposite faces of said inversion fin and said crowned collar, thereby the restoring force of the restoring spring pushing the shroud tube up bringing the shower head to restore the original position, there are sealing loops set upon the contacting surfaces of each pair of adjacent components.  
   
   
       2 . An automatic telescope shower head set for kitchen sink as claimed in  claim 1 , wherein said fitting and said main body can be molded individually into tow parts, and can be secured into one component via thread-joint, in the same way, said shroud tube and the shower head can be also molded tow parts independently, and can be connected together by securing connection.  
   
   
       3 . An automatic telescope shower head set for kitchen sink as claimed in  claim 1 , wherein said main body has a housing built on the bottom downward for supplying a space containing the shower head moving down-up under the water pressure or the restoring spring working as sliding out or sliding back in original position.  
   
   
       4 . An automatic telescope shower head set for kitchen sink as claimed in  claim 1 , wherein said fitting extends a guiding tube axially downward located at the inside of the tube of the main body, coordinating it, said shroud tube has an axial ring groove built on the circle wall for fitting on said guiding tube of said fitting in up-down moving connection.
