The cigarette lighter is a component of all cars that is used to facilitate the ignition of cigarettes when the owner smokes. The cigarette lighter socket is an electronic device similar to a household power source porous socket, which is connected to a car power source through a plug, and then leads to a plurality of cigarette lighter sockets.
