Description

A nebulizer and its electronic cigarette

Technical field

Background technique

At present, the ultrasonic high-frequency atomized electronic cigarette is covered with an oil guiding cotton on the surface of the ultrasonic high-frequency atomizing sheet, and the contact between the oil guiding cotton and the atomizing sheet is in surface contact.

For the atomized sheet of piezoelectric ceramics, after energization, the piezoelectric ceramic sheets do not immediately oscillate the oil guide cotton. Instead, it is energized to generate heat. After the heat reaches a certain level, it will oscillate and atomize the oil guide cotton. Therefore, when the oil guiding cotton is covered on the surface of the piezoelectric ceramic sheet, the piezoelectric ceramic sheet generates heat, but since the oil guiding cotton itself absorbs heat and the contact surface with the piezoelectric ceramic sheet is large, part of the heat is transferred to The oil guide cotton causes the piezoelectric ceramic to take a long time to generate the heat required to achieve its own oscillation. This will make the time from the start of the piezoelectric ceramic piece to the start of the oscillation atomization too long, and the user can take a long time to smoke the first cigarette, and the experience is poor.

Moreover, due to the surface contact, it is often difficult to atomize after the oil-impregnated cotton oil is supersaturated.
