Device can prevent human electric shock, and the mica sheet of addition can completely cut off heat, prevent the damage to hair dryer shell, add at handle
The triode entered, then can when human body is not in contact with hair dryer handle, high current by the way that not, hair dryer can not work,
Force power-off, avoid due to people is in a hurry or forgets to turn off hair dryer switch and caused by fire.But in the program when
The low current circuit in triode can be then closed when people holds handle, and controls alternating current to be communicated to electricity by triode and blows
On various circuit elements in wind, and circuit element is operated, uniquely relies on single triode to control whole circuit
Switch, its induction switching-off effect and precision it is poor and in user when not in use, when the triode in handle has touched
It equally can also make its work during conductive component, its security performance is bad.
Utility model content

Bottom plate 6 is fixedly connected, and the top of protection cylinder 17 is fixedly connected with buckle 19, and the bottom of upper mounted plate 4 offers neck, card
Button 19 is flexibly connected by neck with upper mounted plate 4, when without using hair dryer, is pushed up protection cylinder 17, is blocked buckle 19
In the neck that the bottom of upper mounted plate 4 opens up, the processing of the touch-proof to reaction diaphragm 8 is realized, otherwise is using hair dryer
In the case of, pull downward on protection cylinder 17.By the cooperation between said structure, to the automatic power interruption mechanism of hair drier
Improved, its inductive effects is good and security performance is high, solves when hair dryer is forgotten to turn off after use, at hair dryer
In start shape body, prolonged operation produces substantial amounts of heat, so as to cause to occur fire or it is other dangerous the problem of.
Operation principle：The electric blower that this can be automatically powered off when in use, is held in hair dryer handle 2 in user
There can be a pressure to the reaction diaphragm 8 of the both sides of electric switch housing 5 during electric switch housing 5, because two reaction diaphragms 8 are same
When be pressurized to the longitudinal axis of electric switch housing 5, and the surface of push rod 9 is transferred the pressure to, so that the side of release link 10
The pushing block 12 of connection moves to the longitudinal axis of electric switch housing 5, due to the motion of two pushing blocks 12, so that and reed
15 side is in contact and promotes the motion of two pieces of reeds 15, and the electrode contact 16 for making to connect on two reeds 15 closes, now
Because the bonding wire piece 14 that the top of reed 15 and wire 13 is connected is connected, and the plug of the bottom of wire 13 is connected with general supply,
So two electrode contacts 16, once closing, two wires 13 form circuit loops, make electric heating element in hair drier, electronic
The a series of circuit controling element such as machine and power on, you can using hair drier, when hair dryer is forgotten to turn off after use
When, because user is not applying pressure to the surface of reaction diaphragm 8, return to release link 10 using the reset of back-moving spring 11
To initial position, pushing block 12 is set to depart from the side of reed 15, so that reed 15 returns to initial position, two electrode contacts 16
Separate, two wires 13 are not forming circuit loop, it is achieved thereby that being automatically powered off to hair drier.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
