Abstract: Disclosed is an electronic cigarette lighting device with a safety mechanism, and the device includes a casing with a combustion-supporting hole formed on the casing, a heat generating unit installed in the casing and alternately positioned with the combustion-supporting hole, and a slide cover installed at the top of the casing and normally covered onto the combustion-supporting hole. After the slide cover is pushed to expose the combustion-supporting hole, the heat generating unit starts generating heat to produce high temperature. A safety mechanism is installed between the casing and the slide cover and capable of blocking the slide cover, such that a user has to release the blocked status of the safety mechanism first before the user can push the slide cover and uses the electronic cigarette lighting device, so that the device can prevent an improper operation of the cigarette lighting device and improve safety.
