Electronic atomization device with adjustable air inlet

Abstract

Disclosed is an electronic atomization device with an adjustable air inlet, which includes a cigarette holder, an atomizer connected to the cigarette holder and a battery assembly for supplying power to the atomizer. An air inlet is disposed at an upper portion of the atomizer for connecting the atomizer to outside world and a switch assembly is disposed between the atomizer and the cigarette holder for opening or closing the air inlet. As disclosed in the present invention, the air inlet can be closed completely by means of the switch assembly thereby preventing the condensate and liquid flavor from flowing to the outside world, avoiding the outsider surface of the electronic atomization device getting dirty and reducing the possibility of the damage of the battery assembly.
