         4 . The vaporizer of  claim 3 , wherein a position of the second heat conducting portion away from the first heat conducting portion is provided with a vent hole,
 wherein at least one air inlet hole is provided at a position of the second heat conducting portion close to the first heat conducting portion or on the vaporization sleeve, and   wherein the vent hole is in communication with the outside air, the air inlet hole is in communication with the vaporization cavity, one end of the first airway is in communication with the vent hole, and an other end is in communication with the air inlet hole.   
     
     
         5 . The vaporizer of  claim 3 , wherein the flange comprises a plurality of arc-shaped protrusions provided at intervals, and
 wherein the plurality of arc-shaped protrusions form the first airway with the inner side wall of the outer housing and an outer side wall of the heat conducting element.   
     
     
         6 . The vaporizer of  claim 3 , wherein the flange comprises a plurality of annular protrusions provided at intervals,
 wherein a first sub-airway is formed between two adjacent annular protrusions of the plurality of annular protrusions, each annular protrusion of the plurality of annular protrusions having a notch causing two adjacent sub-airways to be in communication with each other, and   wherein notches on the two adjacent annular protrusions of the plurality of annular protrusions are provided in a staggered manner.   
     
     
         7 . The vaporizer of  claim 6 , wherein a plane on which the plurality annular protrusions are located is perpendicular to an axial direction of the heat conducting element. 
     
     
         8 . The vaporizer of  claim 3 , wherein the flange comprises a spiral, and the first airway comprises a spiral airway. 
     
     
         9 . The vaporizer of  claim 5 , further comprising:
 a liquid storage cavity shell sleeved at least on an outer side of the vaporization sleeve and cooperating with the outer side wall of the vaporization sleeve to form a liquid storage cavity,   wherein the outer housing is sleeved on an outer side of the liquid storage cavity shell and is arranged to be spaced apart from the liquid storage cavity shell to form a thermal insulation space.   
     
     
         10 . The vaporizer of  claim 9 , further comprising:
 a heat dissipation sleeve sleeved on the outer side of the liquid storage cavity shell and configured to absorb heat on the liquid storage cavity shell.   
     
     
         11 . The vaporizer of  claim 10 , wherein the heat dissipation sleeve comprises a connecting sleeve and several connecting bars arranged on an outer side wall of the connecting sleeve, and
 wherein the several connecting bars are arranged at intervals along a circumferential direction of the connecting sleeve and are perpendicular to an axial direction of the connecting sleeve.   
     
     
         12 . The vaporizer of  claim 11 , wherein a radial size of the second heat conducting portion is greater a radial size of the first heat conducting portion,
 wherein an edge of a side surface of the second heat conducting portion facing the vaporization sleeve is provided with several avoidance portions,   wherein each of the at least one air inlet hole is correspondingly provided at a position in which each avoidance portion of the several avoidance portions is located, and   wherein two adjacent connecting bars of the several connecting bars cooperate with a side wall of the several avoidance portions to form a second airway, the second airway being in communication with the first airway.   
     
     
         13 . The vaporizer of  claim 10 , wherein a material of the heat conducting element comprises metal, and
 wherein a material of the heat dissipation sleeve comprises plastic.   
     
     
         14 . An electronic vaporization apparatus, comprising:
 a power supply component; and   the vaporizer of  claim 1  connected to the power supply component,   wherein the power supply component is configured to supply power to the vaporizer, and   wherein the vaporizer is configured to heat and vaporize an aerosol-forming substrate when powered on.
