Abstract
This application provides an atomizer and an electronic atomization device. The atomizer includes a housing, and the housing is internally provided with: a liquid storage cavity; an atomization assembly; a sealing element; a holder, configured to support the sealing element; and an air channel, including a first channel portion formed between the side surface of the holder and the sealing element and a second channel portion formed between the upper surface of the holder and the sealing element, where the first channel portion has a cross-sectional area greater than that of the second channel portion. The atomizer can supplement air to the liquid storage cavity to relieve or balance the negative pressure in the liquid storage cavity through the air channel; and the air channel including a portion with a different cross-sectional area, is advantageous for air to overcome the pressure of a liquid substrate into the liquid storage cavity.
