Atomizer switch device in electronic cigarette

Abstract

An atomizer switch device provided in a disposable electronic cigarette comprises a key-switch ( 1 ), a battery ( 3 ) and a heating unit ( 2 ). The key switch ( 1 ) is provided on the housing of the disposable electronic cigarette and connected in series in the current loop comprising the battery ( 3 ) and the heating unit ( 2 ). The cost of the disposable electronic cigarette is decreased by using the atomizer switch device.
