         8 . The electronic vaporization device of  claim 7 , wherein the vent tube comprises a step surface, the vent tube being sleeved in the assembling hole, and
 wherein the second seal end abuts against the step surface and seals the second seal end and the vent tube after the assembly is completed.   
     
     
         9 . The electronic vaporization device of  claim 8 , wherein the outwardly expanding opening section is arranged on the second seal end,
 wherein an inner wall of the outwardly expanding opening section and the step surface are both configured as inclined surfaces that match each other,   wherein the vent tube is sleeved in the assembling hole, and   wherein the inner wall of the outwardly expanding opening section abuts against the step surface in a limiting manner after the assembly is completed.   
     
     
         10 . The electronic vaporization device of  claim 1 , further comprising:
 a vaporization assembly,   wherein a vaporization cavity that is in communication with the liquid storage cavity is formed in the vent tube, and   wherein the vaporization assembly is assembled in the vaporization cavity.   
     
     
         11 . The electronic vaporization device of  claim 1 , further comprising:
 a battery core assembly,   wherein the housing assembly comprises a first housing,   wherein the battery core assembly is sleeved in the first housing,   wherein one end of the vent tube connected to the battery core assembly and an other end of the vent tube is sleeved at intervals with the first housing, and   wherein the liquid storage cavity is defined and formed between the vent tube and the first housing.   
     
     
         12 . The electronic vaporization device of  claim 1 , further comprising:
