Abstract
This application provides an e-cigarette vaporizer and an e-cigarette. The vaporizer includes a liquid storage cavity, configured to store a liquid substrate; an air channel, providing a flowing path for external air to enter the liquid storage cavity and provided with a communication opening for the external air to enter the liquid storage cavity; and a sealing element, including a blocking part sealing the communication opening, where the blocking part is configured to open at least a part of the communication opening in response to a change of a negative pressure in the liquid storage cavity for the external air to enter the liquid storage cavity. A flexible component can open the air channel in response to the change of the negative pressure in the liquid storage cavity due to flexibility, so that the external air can enter the liquid storage cavity to reduce the negative pressure.
