Automobile-mounted cigarette lighter with protection device

Abstract

The invention discloses an automobile-mounted cigarette lighter with a protection device. When bimetallic strips of existing cigarette lighters can not be popped, motormeters are burnt out due to too high temperatures. A return spring sleeves a guide positioning pipe which sleeves a connection bar, the tail portion of the connection bar and a draw button are fixed, one end of a resistance wire is embedded into a kerf of the head portion of the connection bar, the other end of the resistance wire is fixed on the inner wall of a resistance seat, a bimetallic strip is embedded into a groove in the top of a porcelain seat, the bottom of the porcelain seat is embedded into the inner wall of the bottom of a casing, the bottom of a conductive spring is snapped into the porcelain seat, the resistance seat is arranged at the top of the bimetallic strip, a box body of a thermal insulation box is arranged at the bottom of the casing, the top of a plastic seat is embedded into a base cover of the thermal insulation box, the top of a lug plate is embedded into the top of the plastic seat, a wire holder is arranged at the bottom of the lug plate, and a clamp nut compresses the wire holder. According to the automobile-mounted cigarette lighter with the protection device, when the bimetallic strip can not pop up the resistance seat, a circuit module forcibly turns off a circuit to guarantee safety of the cigarette lighter and motormeters.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a car cigarette lighter, in particular to a car cigarette lighter with a protective device. Background technique [0002] A cigarette lighter is a car device whose main function is to light a cigarette. When the cigarette lighter is pressed in, the heating part is embedded in the bimetal sheet of the cigarette lighter socket, and a loop is formed inside, the circuit is turned on, and the resistance wire will be heated to a temperature sufficient to make the cigarette burn (1050-1100°C). , the user can use to light a cigarette. But now many cigarette lighters have a common problem, that is, when the bimetal sheet cannot pop out of the heating part of the cigarette lighter, the resistance wire is always heated, and when the temperature is too high, it will burn out the car instrument or other parts; A wire is added to the smoke device to cut off the power when the temperature is...
