Description

Technical Field

The present invention belongs to the technical field of electronic cigarettes, and particularly relates to an ultrasonic electronic cigarette atomizer.

Technical Field

At present, electronic cigarette has become a relatively mature smoking alternative on the market. Compared with the traditional heating atomization by an electric heating wire, the ultrasonic electronic cigarette atomizes tobacco tar by using an ultrasonic vibration atomization piece, the atomization temperature is lower, and the temperature during atomization process does not exceed 180 degrees Celsius, therefore the problem of producing formaldehyde, carbon monoxide and other harmful substances at high temperatures is effectively solved, meanwhile, no peculiar smell will be produced due to scorching at a high temperature, and thus the atomization taste is effectively improved.
The existing ultrasonic electronic cigarette atomizer comprises a tobacco tar cup and a suction nozzle connected with one end of a side wall of the tobacco tar cup, wherein an atomization piece and a liquid guide structure are provided in the tobacco tar cup, the liquid guide structure communicates the atomization piece and a tobacco tar storage cavity in the tobacco tar cup, and the smoke produced by the atomization piece after atomizing tobacco tar enters the oral cavity of a smoker from the suction nozzle. The atomization piece essentially comprises a front surface and a back surface, namely, a first surface and a second surface, that can atomize the tobacco tar, however, the liquid guide structure is only in contact with one surface of the atomization piece actually, namely, the liquid guide structure only guides the tobacco tar in the tobacco tar storage cavity to one surface of the atomization piece, therefore the atomization piece in the existing ultrasonic electronic cigarette atomizer only performs single-surface atomization, as a result, the amount of smoke is relatively small, therefore the atomization efficiency is low, and the energy utilization rate is low. Meanwhile, as the atomization piece performs the single-surface atomization, only one kind of tobacco tar can be atomized at a time, the taste of smoke is single, and the requirements for multiple tastes cannot be satisfied.
