Electronic vaporization device and vaporizer thereof

Abstract

A vaporizer includes: a shell; an outer tube disposed in the shell; and an inner tube disposed in the outer tube. An inhalation opening is formed at an end of the shell. A main airway in communication with the inhalation opening is formed inside the inner tube. An auxiliary airway in communication with the inhalation opening is formed between the outer tube and the inner tube.

What is claimed is: 
     
         1 . A vaporizer, comprising:
 a shell;   an outer tube disposed in the shell; and   an inner tube disposed in the outer tube,   wherein an inhalation opening is formed at an end of the shell,   wherein a main airway in communication with the inhalation opening is formed inside the inner tube, and   wherein an auxiliary airway in communication with the inhalation opening is formed between the outer tube and the inner tube.   
     
     
         2 . The vaporizer of  claim 1 , wherein the auxiliary airway comprises at least one air guide groove that is recessed and formed in an outer wall surface of the inner tube and/or an inner wall surface of the outer tube. 
     
     
         3 . The vaporizer of  claim 1 , wherein the auxiliary airway comprises an annular airflow channel formed between an outer wall surface of the inner tube and an inner wall surface of the outer tube. 
     
     
         4 . The vaporizer of  claim 1 , further comprising:
 a vaporization assembly disposed in the shell and is in communication with the main airway.   
     
     
         5 . The vaporizer of  claim 4 , wherein a liquid storage cavity is formed between the shell and the outer tube, and
 wherein the vaporization assembly is at least partially disposed in the inner tube and is in communication with the liquid storage cavity.   
     
     
         6 . The vaporizer of  claim 5 , wherein at least one first liquid inlet in communication with the liquid storage cavity is formed in the outer tube, and
 wherein at least one second liquid inlet that communicates the at least one first liquid inlet with the vaporization assembly is formed in the inner tube.   
     
     
         7 . The vaporizer of  claim 1 , wherein an air inlet channel is formed in the shell,
 wherein two ends of the main airway are respectively in communication with the air inlet channel and the inhalation opening, and   wherein two ends of the auxiliary airway are respectively in communication with the air inlet channel and the inhalation opening.   
     
     
         8 . The vaporizer of  claim 7 , wherein the shell comprises a liquid storage shell and a base disposed at a lower end of the liquid storage shell, and
 wherein the air inlet channel is formed in the base.   
     
     
         9 . The vaporizer of  claim 8 , wherein a first mounting hole that is concave downward is formed in a top surface of the base, and
 wherein lower ends of the outer tube and the inner tube are both accommodated in the first mounting hole.   
     
     
         10 . The vaporizer of  claim 9 , wherein a support surface is provided at a bottom of the first mounting hole,
 wherein lower end surfaces of the outer tube and the inner tube both abut against the support surface, and   wherein at least one vent opening that communicates the air inlet channel with the auxiliary airway is formed in the inner tube.   
     
     
         11 . The vaporizer of  claim 8 , wherein the shell comprises a suction nozzle disposed at an upper end of the liquid storage shell,
 wherein an air outlet hole is formed in the suction nozzle, and   wherein the inhalation opening is formed at an outlet at an upper end of the air outlet hole.   
     
     
         12 . The vaporizer of  claim 11 , wherein upper ends of the outer tube and the inner tube both extend into the air outlet hole. 
     
     
         13 . An electronic vaporization device, comprising:
 the vaporizer of  claim 1 ; and   an airflow sensor in communication with the auxiliary airway and the main airway.
