In the above process, the rotating air guiding member 3 is rotated circumferentially by a certain angle (for example, 45 degrees), and the rotating air guiding member air guiding hole 31 on the rotating air guiding member 3 and the fixed air guiding member 4 are The fixed air guiding member air guiding hole 41 is in a non-opposing state, the air flow passage is not connected, and the device returns to a natural state, that is, the device air flow passage is in a closed state.

The beneficial effects of the invention:

In view of the deficiencies of the existing mouthpiece and the electronic cigarette airflow passage, the present invention provides a device for automatically opening/closing the airflow passage by inserting the cigarette when the cigarette holder or the electronic cigarette is not in use, when the airflow passage is automatically closed. This can not only save the internal volatile substances more effectively, but also enable consumers to more easily open and close the airflow channel when needed, which effectively enhances the consumer's experience.
