Vaporizer and electronic vaporization device

A vaporizer, comprising an outer housing, the outer housing having a longitudinal direction and a horizontal direction perpendicular to the longitudinal direction, wherein the outer housing is internally provided with:

• a liquid storage cavity, configured to store a liquid substrate;
• a liquid absorbing element, extending in the horizontal direction, and constructed to be in fluid communication with the liquid storage cavity to absorb the liquid substrate;
• a first support member, located between the liquid absorbing element and the liquid storage cavity in the longitudinal direction, and at least partially defining a vaporization chamber surrounding the liquid absorbing element;
• a heating element, combined with the liquid absorbing element and configured to heat at least a part of the liquid substrate of the liquid absorbing element to form and release an aerosol to the vaporization chamber;
• and
• a vapor output channel, configured to output the aerosol in the vaporization chamber and comprising a through hole extending in the longitudinal direction on the first support member, wherein:
• the first support member is provided with a blocking part located between the heating element and the through hole;
• the blocking part is provided with a side opening, and at least a part of the vaporization chamber is in airflow communication with the vapor output channel through the side opening;
• and the side opening is opposite to at least a part of the heating element in the longitudinal direction.
