Electronic vaporization device and vaporizer thereof

Abstract

A vaporizer includes: a shell; a base inserted into a lower end of the shell; a vent tube passing through the shell; a liquid storage cavity formed between an outer wall surface of the vent tube and an inner wall surface of the shell; a vaporization core provided in the vent tube and in communication with the liquid storage cavity in a liquid guide manner; and at least one vent channel communicating the liquid storage cavity with an outside. A lower end of the vent tube is inserted into the base. The at least one vent channel is formed between the base and the shell and/or between the base and the vent tube.

What is claimed is: 
     
         1 . A vaporizer, comprising:
 a shell;   a base inserted into a lower end of the shell;   a vent tube passing through the shell;   a liquid storage cavity formed between an outer wall surface of the vent tube and an inner wall surface of the shell;   a vaporization core provided in the vent tube and in communication with the liquid storage cavity in a liquid guide manner; and   at least one vent channel communicating the liquid storage cavity with an outside,   wherein a lower end of the vent tube is inserted into the base, and   wherein the at least one vent channel is formed between the base and the shell and/or between the base and the vent tube.   
     
     
         2 . The vaporizer of  claim 1 , wherein an upper end surface of the base extends downward to form a mounting hole,
 wherein the vent tube comprises an accommodating section accommodated in the mounting hole, and   wherein an outer wall surface of the accommodating section and/or a hole wall surface of the mounting hole is recessed to form at least one vent channel.   
     
     
         3 . The vaporizer of  claim 2 , wherein a lower end surface of the base extends upward to form an electrode hole in communication with the mounting hole,
 wherein the vaporizer further comprises an electrode column that passes through the electrode hole and forms a vent gap with the hole wall surface of the electrode hole, and   wherein the at least one vent channel is in communication with the vent gap.   
     
     
         4 . The vaporizer of  claim 3 , wherein at least one air inlet hole is provided in a hole wall of the electrode hole to communicate the vent gap with the outside. 
     
     
         5 . The vaporizer of  claim 3 , further comprising:
 an insulating sleeve fitted between an outer wall surface of the electrode column and a hole wall surface of the electrode hole,   wherein at least one vent passage is formed on the insulating sleeve, and   wherein the vent gap is in communication with the outside via the at least one vent passage.   
     
     
         6 . The vaporizer of  claim 3 , wherein a diameter of the mounting hole is larger than a diameter of the electrode hole, and
 wherein the diameter of the mounting hole matches an outer diameter of the accommodating section.   
     
     
         7 . The vaporizer of  claim 1 , wherein an outer wall surface of the base is recessed to form the at least one vent channel. 
     
     
         8 . The vaporizer of  claim 1 , wherein the at least one vent channel extends in a linear shape. 
     
     
         9 . The vaporizer of  claim 1 , wherein the at least one vent channel extends in a nonlinear shape. 
     
     
         10 . The vaporizer of  claim 9 , wherein the nonlinear shape comprises at least one of a zigzag shape, a helical shape, and a curved shape. 
     
     
         11 . An electronic vaporization device, comprising:
 the vaporizer of  claim 1 .
