Rotating ejection type oozing hose for plant cultivation

Abstract

A rotating ejection type oozing hose comprises a rotation generator formed at an ejection opening at an interval along a longitudinal direction of a hose, applying a rotational force to a flow of water from an inner space of the hose to an outer space. The rotation generator comprises a barrel-shaped rotating space extended from the ejection opening and formed inside the hose. The rotating space is defined by a side portion formed to be extended from an inner wall of the hose and having a rotational force applying passage horizontally connecting the inner space of the hose to the rotating space and a bottom portion for closing a lower end of the side portion. The rotational force applying passage faces a point deviating from a center portion of the rotating space, applying a rotational force to water flowing into the rotating space through the rotational force applying passage.

What is claimed is: 
     
         1 . A rotating ejection type oozing hose for plant cultivation, comprising a plurality of rotation generators ( 200 ) formed at ejection openings ( 102 ) in a line in one band, and wherein an upper surface of the side portion ( 210 ) of each rotation generator ( 200 ) is formed to be attached to an inner surface of the hose ( 100 ); wherein ejection openings ( 102 ) are formed by punching at an interval along a longitudinal direction of a hose ( 100 ) of a soft rubber material, applying a rotational force to a flow of water ejected from an inner space ( 104 ) of the hose ( 100 ) to an outer space ( 106 ) thereof,
 wherein the rotation generator ( 200 ) comprises a barrel-shaped rotating space ( 212 ) extended from the ejection opening ( 102 ) and formed inside the hose ( 100 ),   wherein the rotating space ( 212 ) is defined by a side portion ( 210 ) and a bottom portion ( 240 ), the side portion ( 210 ) formed to be extended from an inner wall of the hose ( 100 ) and having two rotational force applying passages ( 214 ) horizontally connecting the inner space ( 104 ) of the hose ( 100 ) to the rotating space ( 212 ), and the bottom portion ( 240 ) for closing a lower end of the side portion ( 210 ), and   wherein the rotational force applying passages ( 214 ) are oriented to face a point deviating from a center portion P of the rotating space ( 212 ), applying a rotational force to a flow of water flowing into the rotating space ( 212 ) through the rotational force applying passages ( 214 ); and   wherein the two rotational force applying passages ( 214 ) are formed symmetrically with respect to the center of the rotating space ( 212 ).   
     
     
         2 . The rotating ejection type oozing hose of  claim 1 , wherein the rotation generator ( 200 ) further comprises a filter ( 220 ) provided with a filtering hole ( 222 ) for filtering water flowing into the rotational force applying passages ( 214 ) from the inner space ( 104 ); and a decompressor ( 250 ) having at least one bending path for adjusting a pressure of water flowing into the rotational force applying passages ( 214 ). 
     
     
         3 . The rotating ejection type oozing hose of  claim 1 , wherein the rotation generator ( 200 ) further comprises an ascending force reinforcement protrusion ( 230 ) formed on the bottom portion ( 240 ) corresponding to the center portion of the rotating space ( 212 ), more reinforcing an ascending force of water ascending to the ejection opening ( 102 ) while rotating in the inner space ( 212 ).
