Description

[0001] The disclosure relates to an atomizer and electronic cigarette comprising the same.

[0002] Conventional atomizers include e-liquid inlets of which the openings cannot be adjusted or sealed, causing excess e-liquid to flow to heating elements and leak outside the atomizers. During replacement of the heating elements, the e-liquid may flow out of the atomizers through the e-liquid inlets, which results in e-liquid waste. US 2020 / 245685 A1 discloses an electronic cigarette comprising a rotary valve. The rotary valve includes a first body, a second body, and a biasing member configured to exert a biasing force between the first and second bodies. The valve is actuated between an open position and a closed position based on the relative angular position of the first body with respect to the second body. CN 210137809 U discloses an atomizer. The atomizer includes a sealer, and a liquid-sealing component movable with respect to the sealer. A first chamfered part is arranged at one end of the liquid-sealing component, a second chamfered part is arranged at one end of the sealer. When the first chamfered part is in contact with the second chamfered part, the e-liquid on one side of the liquid-sealing component is prevented from flowing to the other side. When the first chamfered part is separated from the second chamfered part, a gap is formed between them, allowing the e-liquid to pass through the gap and flow to the opposite side of the liquid-sealing component.
