Abstract
The utility model discloses a temperature adjustable electrothermal cap, and the utility model belongs to the hair-waving appliance, composed of a transformer, a voltage regulating control circuit and an electrothermal cap. The utility model is low-voltage and safe. The voltage on both ends of the heating wires in the electrothermal cap can be adjusted in the 20-36v. The temperature of the electrothermal cap can be continuously stepless-adjusted in the 30-60 DEG C, and the utility model has the advantages that the utility model saves energy, the utility model does not pollute the environment, and the utility model has convenient operation.
Description
The utility model is to belong to a kind of hair-waving apparatus.
At present, along with improving constantly of people's living standard, the more and more and the most frequently used chemistry hair-waving of the people of hair-waving needs can make Hair styling through overheated warming up.Past is to adopt the hot water towel to carry out heat to warm up always, and this method has many inconvenience.The one, hot towel scalds to such an extent that barber and client are unable to stand, and variations in temperature is big.Heat-insulating property is poor; The 2nd, waste is big, and scalding a hair needs two bottles of water, and utilization rate is low; The 3rd, the coal stove contaminated environment that is used to heat up water.
Task of the present utility model provides a kind of temperature adjustable electrically heated cap, works under the low pressure situation, guarantees safety, but quick heating, good heat insulating continuous stepless temperature adjustment, and under the mains fluctuations situation, still can guarantee safe work.
The utility model adopts a low-tension transformer B to guarantee the not having danger of electric shock, constitutes voltage-adjustable control loop by bidirectional triode thyristor 3CTS, variable potentiometer W etc., with control load r
1, r
2(heating wire in the electric heating cap) makes its terminal voltage adjustable arbitrarily between 20～36V, and the temperature in the electric heating cap is adjustable arbitrarily between 30～60 ℃.
Below in conjunction with accompanying drawing the utility model is explained in detail.
The utility model comprises a low-tension transformer B, its primary coil and capacitor C

2The short circuit that short causes.
The utility model is work like this:
When connecting power supply, convert supply voltage 220V to 36V low pressure by transformer B, pass through resistance R
1, potentiometer W is to capacitor C
2Carry out the index charging, at this moment, diac 2CTS conducting, capacitor C
2The terminal voltage control that is added in bidirectional triode thyristor 3CTS extremely go up.Work as capacitor C
2Terminal voltage when being raised to certain value, bidirectional triode thyristor 3CTS conducting at this moment, is inserted CT
1And CT
2Load---heating wire r in the electric heating cap
1, r
2On obtain the voltage of certain value, make and produce corresponding temperature in the electric heating cap.
When changing the resistance of potentiometer W, capacitor C
2Corresponding the changing of charging index.Thereby changed the angle of flow of bidirectional triode thyristor 3CTS, at this moment, r
1, r
2On just obtain different magnitudes of voltage, the temperature in the electric heating cap is changed, reach the purpose of stepless temperature-regulating, meanwhile, LED is also luminous, shows the intensification situation in the electric heating cap.
Be one group of parameter of the utility model most preferred embodiment below, heating wire r
