Abstract
An ultrasonic electronic cigarette atomizer is disclosed, including an atomization core, an atomizer housing, and a liquid bin. When liquid is filled into the liquid bin, the liquid passing hole is closed and the air outlet channel is closed, to avoid leakage or immersion of liquid, the atomizer is clean and sanitary, waste is avoided, and cost is saved. The whole operation is very simple, the atomization core is convenient to replace, hands are not stained with liquid, and the liquid is convenient to fill. The cigarette liquid is unlikely to flow out through the liquid filling hole, and large granular cigarette liquid generated in atomization can be recycled.
