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 overheating alarm plug for a hair dryer. The plug comprises a housing; two external connection electric columns are inserted into the outer wall of the housing in a penetrating manner; two internal connection electric columns corresponding to the two external connection electric columns in position are fixed to the inner wall of the housing; a rotation groove is formed in the side wall of the housing and penetrates through the side wall of the housing; a rotating plate is slidably connected to the inner wall of the rotation groove; insulating plates are fixed to thetwo ends of the rotating plate; two sets of symmetrically-arranged elastic pieces are fixed to the side wall of the rotating plate. According to the plug, when the temperature of the position of the plug rises to a certain degree, an air bag expands to be large enough, so that connecting sheets are in contact with power connection sheets, and a lamp tube is electrified and flashes, so that a usercan be warned; since the noise of the hair dryer in a using process is large and the hair dryer is close to the ears of the user, the receiving capacity of the user to external sound is weakened, thesensitivity of the user to light is high, and therefore, the warning effect of the flashing light is better, and the user can respond more quickly.

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 ...
