Abstract

An atomizer and an electronic cigarette. The electronic cigarette includes an electronic cigarette body. Sequentially provided on the electronic cigarette body are a mouthpiece cover, an atomizing component, and a battery component. The mouthpiece cover covers an end surface of the atomizing component. Provided within the atomizing component are an e-liquid storage space used for storing an e-liquid, an atomizing core used for atomizing the e-liquid and electrically connected to the battery component, and a smoke channel used for discharging smoke to the mouthpiece cover and extended along the axis of the atomizing component. At least two smoke outlet gaps in communication with the smoke channel are formed on the end surface of the mouthpiece cover. The smoke outlet gaps are extended from the center of the end surface of the mouthpiece cover towards the periphery of the end surface of the mouthpiece cover.
