[0008] The mouthpiece, the protective cover, and the housing can be of stainless steel.

[0009] The support, the base, the atomization unit, and the housing can be in threaded connection.

[0010] Advantages of the electronic cigarette according to embodiments of the disclosure are summarized as follows. The protective cover can move up and down along the cylinder. To refill the atomization unit, the protective cover can be rotated upwards, and the slide block is pushed to one side. The e-liquid inlet of the atomizing assembly is exposed, and the e-liquid can be injected. After refilling, the slide block is pushed back and the protective cover descends to seal the e-liquid inlet. The mouthpiece, the protective cover, and the housing are of stainless steel.
