Abstract: An exemplary atomizer for an electronic cigarette includes an atomizing sleeve, a liquid chamber sealed in the atomizing sleeve, and an atomizing assembly arranged at a bottom end of the sleeve. The atomizing sleeve defines an air outlet at a top end thereof. The atomizing assembly includes a hollow fixing holder, a transmission component, a seal cover, an elastic element, an air pipe, and a heating component. The seal cover is movable with the transmission component between a first position where a liquid passage is formed between the seal cover and the fixing holder, and a second position where the liquid passage is closed. The elastic element is configured for storing energy when the liquid passage is open, and for driving the transmission component to move downwards and bringing the seal cover to move downwards to close the liquid passage.
