Atomization tube

Abstract

An atomization tube is configured to be disposed within a liquid storage cavity of an electronic cigarette device. The atomization tube includes a tubular first portion configured to receive a heating core, and a tubular second portion. The tubular first portion includes an inlet hole and an exhaust hole. Liquid enters the tubular first portion from the liquid storage cavity through the inlet hole to contact the heating core.

What is claimed is: 
     
         1 . An atomization tube configured to be disposed within a liquid storage cavity of an electronic cigarette device, comprising:
 a tubular first portion configured to receive a heating core; and   a tubular second portion;   wherein the tubular first portion includes an inlet hole and an exhaust hole; and wherein liquid enters the tubular first portion from the liquid storage cavity through the inlet hole to contact the heating core.   
     
     
         2 . The atomization tube of  claim 1 , wherein the exhaust hole is disposed on the tubular first portion adjacent an upper portion of the heating core. 
     
     
         3 . The atomization tube of  claim 1 , wherein the inlet hole is disposed on the tubular first portion towards a bottom of the liquid storage cavity. 
     
     
         4 . The atomization tube of  claim 1 , wherein tubular first portion includes cotton wrapped around the heating core. 
     
     
         5 . The atomization tube of  claim 1 , further comprising a blocking member disposed in the tubular first portion between the heating core and the tubular second portion. 
     
     
         6 . The atomization tube of  claim 5 , wherein the exhaust hole is disposed on the tubular first portion adjacent a portion of the blocking member. 
     
     
         7 . The atomization tube of  claim 5 , wherein the blocking member includes an exhaust portion and an abutment portion; and wherein the abutment portion is configured to abut against an inner wall of the atomization tube. 
     
     
         8 . The atomization tube of  claim 7 , wherein an outer diameter of the abutment portion is greater than an outer diameter of the exhaust portion. 
     
     
         9 . The atomization tube of  claim 7 , wherein a distance between an outer diameter of the exhaust portion and the inner wall of the atomization tube surrounding the exhaust portion defines a gap between the exhaust portion and a portion of the atomization tube surrounding the exhaust portion. 
     
     
         10 . The atomization tube of  claim 7 , wherein abutment of the abutment portion against the inner wall of the atomization tube aligns the exhaust portion with the exhaust hole, and whereby gas flows between the exhaust portion and the exhaust hole. 
     
     
         11 . The atomization tube of  claim 5 , wherein the blocking member includes a central channel extends through which gas passes from the heating core into the tubular second portion. 
     
     
         12 . The atomization tube of  claim 5 , wherein the blocking member further includes a protruding portion and a chamfer portion disposed between the protruding portion and the exhaust portion. 
     
     
         13 . The atomization tube of  claim 12 , wherein the protruding portion has a smaller outer diameter than the outer diameter of the exhaust portion. 
     
     
         14 . The atomization tube of  claim 12 , wherein liquid condenses on at least a portion of at least one of the protruding portion and the chamfer portion, and wherein the condensed liquid then moves towards the chamfer portion along a portion of the outer diameter of the exhaust portion. 
     
     
         15 . The atomization tube of  claim 1 , wherein the heating core is configured to vaporize liquid, and the tubular second portion is configured to guide vaporized liquid upwards.
