An atomizer, comprising a device (10) for storing a liquid to be atomized and an atomizing device (40). The device (10) for storing a liquid to be atomized comprises a container (11) for storing a liquid to be atomized, wherein the container (11) is axially provided with a through hole (12), a plurality of liquid outlet holes (13) communicating with the container is provided on the inner wall of the through hole (12), a sealing structure (20) capable of sliding up and down is further provided in the through hole (12), and the sealing structure (20) seals the liquid outlet holes (13) and is configured to allow air in the though hole (12) to flow through. A heating and atomizing barrel (30) is provided on the atomizing device (40), wherein an adsorption layer (32) is provided on the outer wall of the heating and atomizing barrel (30), an electric heating device (31) pressing against the adsorption layer (32) is provided on the inner wall of the heating and atomizing barrel (30), and the heating and atomizing barrel (30) matches and is inserted into the device (10) for storing a liquid to be atomized so that the adsorption layer (32) presses against the inner wall of the through hole and covers the liquid outlet holes (13). The device (10) for storing a liquid to be atomized has a simple structure and good sealing performance. The atomizer has an advantage of quick and easy use and replacement of the device for storing a liquid to be atomized.La présente invention concerne un atomiseur, comprenant un dispositif de stockage (10) pour un liquide à atomiser et un dispositif datomisation (40).
