In the ultrasonic electronic cigarette atomizer on the market at present, an ultrasonic atomization sheet comprises a piezoelectric ceramic matrix and an upper surface electrode and a lower surface electrode which are respectively arranged on the upper surface and the lower surface of the piezoelectric ceramic matrix, and when two poles of a power supply are respectively connected with the upper surface electrode and the lower surface electrode, the piezoelectric ceramic matrix can generate high-frequency oscillation, so that smoke oil is atomized into smoke on the surface of the piezoelectric ceramic matrix. When using ultrasonic atomization piece atomizing tobacco tar, the ultrasonic atomization piece is equivalent to a electric capacity in atomizing circuit, so the energy that ultrasonic atomization piece bore after the circuit opens circuit is nowhere released, ultrasonic atomization piece releases the high energy in the twinkling of an eye when putting through the circuit once more on each components and parts of mainboard, consequently burns components and parts easily, for example the MOS pipe is punctured by high voltage to influence the normal work of circuit.

For solving this kind of situation, can insert a resistance board between the upper surface electrode of the ultrasonic atomization piece of current ultrasonic wave electron smog spinning disk atomiser and the lower surface electrode, make the atomizer after the outage, the resistance on ultrasonic atomization piece and the resistance board forms a closed circuit to consume the energy of ultrasonic atomization piece self storage after the circular telegram breaks off again, guarantee that the ultrasonic atomization piece can normally work after circular telegram once more, avoid ultrasonic atomization piece to release instantaneous high voltage and burn out other electronic components after circular telegram once more. However, the conventional resistor plate needs many parts for assembly, has many processes and high cost, and is fixed and conductive with the upper surface electrode and the lower surface electrode of the ultrasonic atomization sheet through screws or soldering tin, so that the risk of insecure fixation such as insufficient soldering is easy to occur.

In addition, in the existing atomizer, the oil guide cotton is generally clamped and fixed by adjacent components, and sometimes the situation of over-tight clamping occurs, so that the oil guide efficiency of the oil guide cotton is reduced, and the dry burning phenomenon is easy to occur; sometimes, the oil guide cotton is clamped too loosely, so that the oil guide cotton is easy to fall off under the action of a spring pressing the oil guide cotton to the ultrasonic atomization sheet, and even the oil leakage phenomenon occurs.
