The time from the start of the work of the atomizing piece (51) to the start of oscillating atomization is shortened by decreasing the contact area of the tobacco tar guide body, and thus the smoke production speed is higher. Moreover, the phenomenon will not occur that atomization is difficult to implement after the tobacco tar guide body is in a tobacco tar absorption oversaturated state.

Description

Field of the Invention

[0001] The present invention belongs to an atomizer and an electronic cigarette comprising the same.

Background of the Invention

[0002] At present, the existing ultrasonic high frequency atomization electronic cigarette is covered with a piece of tobacco tar guide cotton on the surface of an ultrasonic high frequency atomizing piece, and the contact between the tobacco tar guide cotton and the atomizing piece is surface contact.

[0003] With respect to a piezoelectric ceramic atomizing piece, after powering up, the piezoelectric ceramic piece does not immediately oscillate to atomize the tobacco tar guide cotton. Instead, after powering up, the piezoelectric ceramic first produces heat and then oscillates after the heat reaches a certain degree so as to atomize the tobacco tar guide cotton. Therefore, when the tobacco tar guide cotton is covered on the surface of the piezoelectric ceramic piece and is powered up, the piezoelectric ceramic piece produces heat, but as the tobacco tar guide cotton absorbs the heat itself, and the contact surface between the tobacco tar guide cotton and the piezoelectric ceramic piece is large, a part of heat will be transferred to the tobacco tar guide cotton, such that it takes the piezoelectric ceramic a long time to produce the heat necessary for the oscillation of itself. This causes an over long time from the start of the work of the piezoelectric ceramic piece to the start of oscillating atomization, and the user needs to wait for a long time to inhale the first puff of smoke, accordingly the user experience is poor.

[0004] Moreover, because of the contact between the tobacco tar guide cotton and the piezoelectric ceramic piece is surface contact, the phenomenon often occurs that atomization is difficult to implement after the tobacco tar guide cotton is in a tobacco tar absorption oversaturated state.

Summary of the Invention

[0005] In view of the above problems, the present invention aims at providing an atomizer having a high smoke production speed and a good atomization effect, and an electronic cigarette comprising the same.
