Embodiment

[0017] refer to Figure 1-3 , an overheat alarm plug for a hair dryer, comprising a housing 1, the outer wall of the housing 1 is inserted with two external electric poles 2, and the inner wall of the shell 1 is fixed with two internal electric poles corresponding to the positions of the two external electric poles 2. The column 3 and the side wall of the shell 1 are provided with a turning groove 23, and the inner wall of the turning groove 23 is slidably connected with a turning plate 4, and the turning plate 4 and the turning groove 23 are sealed and slid, so as to prevent external things from contacting the turning plate 4 with enough clearance. In the event of an electric shock, the two ends of the rotating plate 4 are fixed with insulating plates 7. The insulating plates 7 are used to hold the rotating plate 4 to rotate, so as to avoid direct contact with the rotating plate 4 and cause electric shock. The side walls of the rotating plate 4 are fixed with two sets of symme...

Abstract

The invention discloses an overheat alarm plug for a hair dryer, which comprises a casing, the outer wall of the casing is inserted with two external electric posts, and the inner wall of the casing is fixed with two inner plugs corresponding to the positions of the two external electric posts. The side wall of the housing is provided with a turning slot, the inner wall of the turning slot is slidably connected with a turning plate, both ends of the turning plate are fixed with insulating plates, and the side wall of the turning plate is fixed with Two sets of shrapnel arranged symmetrically. The advantage is that when the temperature at the plug position rises to a certain level, the air bag will expand enough to make the connecting piece contact with the connecting piece, so that the lamp tube will flicker when it is powered on, and the user will be warned. Large and close to people's ears, the user's ability to receive external sounds is weakened, and the sensitivity to light is strong. Therefore, using flashing lights to warn has a better effect and enables users to respond faster.

Description

technical field [0001] The invention relates to the technical field of hair dryers, in particular to an overheat alarm plug for a hair dryer. Background technique [0002] The hair dryer is a combination of a set of heating wires and a high-speed small fan. When energized, the heating wire will generate heat, and the wind blown by the fan will become hot air after passing through the heating wire. If only the small fan rotates, but the heating wire is not hot, then what is blown out is only wind but not heat. It is quick and convenient to use, and is widely loved by people. [0003] Generally, the power of the hair dryer is large, and it needs to be used intermittently during use, but it is generally difficult for users to do so, which makes the power line of the hair dryer seriously heated, and the plug position will also heat up, and it is difficult for the device on the hair dryer itself to detect the plug. This makes the temperature of the plug unobservable, and it is ...
