Automobile cigarette lighter and automobile

Abstract

The invention discloses an automobile cigarette lighter and an automobile. The automobile cigarette lighter comprises a shell body, a base and a hot-melting insulating layer, wherein the shell body is connected with a negative electrode of a power source, and an automobile cigarette lighter inserting hole is formed in the shell body; the base is connected with a positive electrode of the power source; and the hot-melting insulating layer is arranged between the base and the shell body, so that when the temperature of the heated automobile cigarette lighter in the automobile cigarette lighter inserting hole exceeds the first preset temperature and the time of duration exceeds the preset time, the hot-melting insulating layer is dissolved, a heating circuit is made to short-circuit, and an overcurrent fuse wire of the automobile cigarette lighter is fused. By means of the automobile cigarette lighter, safety accidents triggered by continuous heating of the cigarette lighter can be avoided, the safety of the automobile is effectively improved, and the whole safety performance of the automobile is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an automobile cigarette lighter and a vehicle. Background technique [0002] The principle of the car cigarette lighter is that when the inner heating core of the cigarette lighter is pressed, the heating core is stuck by the bimetallic sheet on the outer shell of the cigarette lighter, so that a section of the electric heating wire in the middle of the heating core is in contact with the outer shell of the cigarette lighter. The positive contact of the cigarette lighter power supply in the middle of the body base is in contact with it, and because the other section of the electric heating wire is connected to the power supply accessory through the housing, the electric heating wire is energized and heated. When the electric heating wire is heated to a certain temperature, the bimetal sheet on the outer casing of the cigarette lighter is deformed due to heat, which makes it impo...

Problems solved by technology

[0003] However, in long-term use, the bimetal sheet or internal spring of the cigarette lighter will fail due to aging or external force. Once the bimetal sheet or internal spring fails, the heating core will not be normally disconnected from the positive pole of the power supply. The electric heating wire of the cigarette lighter continues to heat, which will cause safety accidents, such as causing the vehicle to ignite spontaneously, greatly reducing the safety of the vehicle
