Atomizer for electronic cigarette

An atomizer for an electronic cigarette, comprising a liquid cartridge device with a liquid outlet, atomization cotton, and an ultrasonic atomization piece, wherein:

• a middle part of the atomization cotton abuts against a central area of the ultrasonic atomization piece by a spring to form an atomization zone, and an end portion of the atomization cotton is pressed against a bottom of the liquid cartridge device and covers the liquid outlet;
• an atomization cavity is formed between the ultrasonic atomization piece and a bottom of the liquid cartridge device, and a gas inlet of the atomization cavity and a gas outlet of the atomization cavity are disposed at a top of the atomization cavity;
• characterized in that:
• the gas inlet of the atomization cavity is misaligned with the liquid outlet, so that the gas flow direction at the gas inlet of the atomization cavity is misaligned with the flow direction of an e-liquid on the atomization cotton, and a gas flow between the gas inlet of the atomization cavity and the gas outlet of the atomization cavity has a turning;
• and
• a gas distribution valve is disposed at the gas outlet of the atomization cavity, at least one groove is disposed on the periphery of the gas distribution valve, and the gas outlet of the atomization cavity is communicated with the atomization cavity through the groove.
