E-cigarette, e-cigarette vaporizer, and vaporization assembly

An e-cigarette vaporizer, configured to vaporize a liquid substrate to generate inhalable aerosols, and the e-cigarette vaporizer comprising:

• a liquid storage cavity, configured to store the liquid substrate;
• a porous body, in fluid communication with the liquid storage cavity to absorb the liquid substrate;
• and
• a heating element, formed on the porous body and configured to heat the liquid substrate in at least a part of the porous body to form aerosols, wherein the heating element comprises a first electrode connection portion, a second electrode connection portion, and a resistance heating trajectory extending between the first electrode connection portion and the second electrode connection portion, wherein:
• the porous body comprises a vaporization surface, and the heating element is formed on the vaporization surface;
• the vaporization surface comprises a length direction and a width direction perpendicular to the length direction;
• the first electrode connection portion and the second electrode connection portion are sequentially arranged along the length direction;
• and
• an area of a region defined by a first imaginary straight line running through a joint of the resistance heating trajectory and the first electrode connection portion along the width direction and a second imaginary straight line running through a joint of the resistance heating trajectory and the second electrode connection portion along the width direction on the vaporization surface is less than two thirds of an area of the vaporization surface.
