E-cigarette atomization device capable of controlling the supply of e-liquid by relative movement of components

Abstract

The present invention provides an atomization generating device for e-cigarettes, comprising an e-liquid storage portion for storing and supplying an e-liquid, an atomizing portion for heating and atomizing the e-liquid, and a sealing portion located between the e-liquid storage portion and the atomizing portion, wherein the e-liquid storage portion and the atomizing portion are designed to be relatively movable to isolate the sealing portion to prevent the e-liquid leakage caused by long-term placement. Before use, e-liquid in the storage tank is not in contact with the outside, which ensures the quality and taste of the e-liquid. When in use, e-liquid flows towards the heating component, and when not in use seals the e-liquid; thereby prolonging storage life of e-liquid, and preventing e-liquid from contacting outside air, and being oscillated by the outside and from flowing out and leaking.
