Electronic vaporization device and vaporizer

Abstract

A vaporizer includes: a liquid storage cavity; a vent tube at least partially mounted in the liquid storage cavity, the vent tube being partially exposed outside the liquid storage cavity, and electrically connectable to an external power supply assembly; and a heating assembly arranged in the vent tube, the heating assembly including a first conductive connecting portion electrically connected to the vent tube.

What is claimed is: 
     
         1 . A vaporizer, comprising:
 a liquid storage cavity;   a vent tube at least partially mounted in the liquid storage cavity, the vent tube being partially exposed outside the liquid storage cavity, and configured to be electrically connected to an external power supply assembly; and   a heating assembly arranged in the vent tube, the heating assembly comprising a first conductive connecting portion electrically connected to the vent tube.   
     
     
         2 . The vaporizer of  claim 1 , further comprising:
 an opening in communication with the liquid storage cavity,   wherein the vent tube comprises a conductive contact portion, and the conductive contact portion is arranged at the opening.   
     
     
         3 . The vaporizer of  claim 2 , wherein the vent tube comprises a main body mounted in the liquid storage cavity, the main body comprises a first end, and the first end is arranged close to the opening, and
 wherein the conductive contact portion is connected to the first end and presents an angle relative to the main body, and extends toward an end surface of the opening.   
     
     
         4 . The vaporizer of  claim 1 , further comprising:
 a conductive structure partially mounted to the vent tube and being insulated from the vent tube, the conductive structure being configured to be electrically connected to the power supply assembly, and   wherein the heating assembly comprises a second conductive connecting portion electrically connected to the conductive structure.   
     
     
         5 . The vaporizer of  claim 4 , further comprising:
 a connecting structure sleeved over an outer periphery of the conductive structure, the connecting structure partially extending through the vent tube and being connected to the power supply assembly, and   wherein the second conductive connecting portion is arranged between the connecting structure and the conductive structure.   
     
     
         6 . The vaporizer of  claim 5 , wherein the connecting structure comprises a non-metallic member. 
     
     
         7 . The vaporizer of  claim 5 , wherein a thread structure is arranged on the connecting structure. 
     
     
         8 . The vaporizer of  claim 1 , wherein the heating assembly comprises a porous element, and
 wherein the first conductive connecting portion extends through the porous element and is electrically connected to the vent tube.   
     
     
         9 . The vaporizer of  claim 8 , further comprising:
 a liquid absorbing structure sleeved over an outer periphery of the porous element.   
     
     
         10 . The vaporizer of  claim 1 , wherein the heating assembly comprises a heating element comprising a heating portion, and
 wherein the first conductive connecting portion is formed at one end of the heating portion.   
     
     
         11 . The vaporizer of  claim 1 , wherein a liquid inlet hole in communication with the liquid storage cavity is arranged on the vent tube. 
     
     
         12 . The vaporizer of  claim 1 , further comprising:
 a vaporization housing,   wherein the liquid storage cavity is formed in the vaporization housing,   wherein an opening in communication with the liquid storage cavity is arranged on the vaporization housing, and   wherein the vent tube is partially exposed at the opening.   
     
     
         13 . An electronic vaporization device, comprising:
 the vaporizer of  claim 1 ; and   the external power supply assembly connected to the vaporizer.   
     
     
         14 . The electronic vaporization device of  claim 13 , wherein the external power supply assembly comprises a power supply and a conductive member connected to the power supply, and
 wherein the conductive member is electrically connected to the vent tube of the vaporizer.
