Description

Hair straightener

Technical field: the utility model relates to a kind of Hair straightener.

Technical background: traditional electric heating Hair straightener has the unmanageable shortcoming of its operating temperature, therefore both has been unfavorable for hairdressing moulding processing, also will produce the adverse consequences of injury to client's hair.

Summary of the invention: the purpose of this utility model is that a kind of Hair straightener will be provided, and it can control the operating temperature that sets automatically, uses thereby help the user.

The utility model is to constitute like this, it comprises that two upper inner have the anchor clamps that metal scalds plate, with the circuit of being located in the anchor clamps housing, it is characterized in that: circuit comprises rectification, the mu balanced circuit part, by first comparator, second comparator, the control signal circuit, controllable silicon and be located at metal and scald main body circuit part that the heat-generating pipe circuit part on the lateral body connects to form behind the plate and temperature sensor and the decimal system or the octal representation device thermoregulation circuit part of scalding plate temperature in order to the reflection metal, described control signal circuit is connected to form by electric capacity and diode reverse and that connect, insert the positive input terminal of first comparator from the dc reference signal voltage of regulator rectifier circuit output, the signal voltage of temperature sensor is imported the negative input end of first comparator, the decimal system or octal representation device are connected on temperature sensor and are linked on the circuit of first comparator, in order to the control design temperature, the output of first comparator is received the negative input end of second comparator, gets the positive input terminal that a faint ac signal is received second comparator again from AC power line.

This stretcher mainly is by supplying the direct current part, temperature control part branch, operating circuit part three parts formation.Wherein partly form by rectification circuit and mu balanced circuit for direct current; Temperature control part branch: produce different control signals by counter, carry out the setting value that dividing potential drop was controlled temperature afterwards by different resistance and negative temperature coefficient respectively; The operating circuit part mainly is the circuit that can produce the heat-generating pipe composition of heat.Principle is: be incorporated into the positive input terminal of operational amplifier for the output direct current of direct current part, but the voltage of the design temperature that counter produces as the negative input end of operational amplifier, both voltages compare control the heating operating circuit work whether.Therefore, the utlity model has can the auto-control temperature, is convenient to the user and manipulates the remarkable advantage effective with hairdressing.

The specific embodiment:

The utility model embodiment comprises that two upper inner have the anchor clamps that metal scalds plate 1, with the circuit of being located in the anchor clamps housing 2, it is characterized in that: circuit comprises rectification, the mu balanced circuit part, by first comparator, second comparator, the control signal circuit, controllable silicon and be located at metal and scald main body circuit part that heat-generating pipe 3 circuit parts on the plate 1 back lateral body connect to form and temperature sensor and the decimal system or the octal representation device thermoregulation circuit part of scalding plate temperature in order to the reflection metal, described control signal circuit is connected to form by electric capacity and diode reverse and that connect, insert the positive input terminal of first comparator from the dc reference signal voltage of regulator rectifier circuit output, the signal voltage of temperature sensor is imported the negative input end of first comparator, the decimal system or octal representation device are connected on temperature sensor and are linked on the circuit of first comparator, in order to the control design temperature, the output of first comparator is received the negative input end of second comparator, gets the positive input terminal that a faint ac signal is received second comparator again from AC power line.

Above-mentioned circuit main body is installed in the anchor clamps handle housing, and the button 4 of the described decimal system or octal representation device thermoregulation circuit part passes from the through hole of handle housing.

In order to guarantee the trouble free service of Hair straightener, be connected with on the above-mentioned heat-generating pipe circuit part in order to realize the fuse of overtemperature protection.

The course of work of the utility model embodiment is as follows:

The voltage of alternating current 220V is through R ₁, D ₁, Z ₁, C ₁The half-wave rectifier voltage circuit output DC source of forming offers dual operational amplifier I _C1As its positive input terminal, i.e. reference signal.I _C24017 is decade counter, and when pressing touch-switch successively, input 14 is imported a pulse signal successively, and its corresponding output 2,4,7,10 is exported high level signal successively, passes through resistance R separately respectively ₁₁, R ₁₀, R ₉, R ₈Carry out dividing potential drop with negative temperature coefficient (NTC) and obtain different voltage as dual operational amplifier I _C1Negative input end 2 so just can obtain different desired temperatures.When temperature is low, R _tResistance bigger, I _C12 ends when being higher than the current potential of reference signal of 3 ends, 1 end is output as level "0", is input to the negative input end 6 of 5,6,7 comparators of forming, by alternating current 220V through resistance R ₆, R ₇Dividing potential drop obtains a faint AC signal and is passed to positive input terminal 5, and at this moment the current potential of 5 ends is higher than the current potential of 6 ends, and 7 ends just have output signal, through C ₂, D ₂, D ₃Produce a pulse signal and trigger bidirectional triode thyristor VT ₁Conducting, the work of heat-generating pipe energising at this moment, heatable.Raise gradually as if temperature, then R _tResistance reduce I gradually _C12 terminal potentials just descend, when temperature reaches setting value, I _C12 ends be lower than the voltage of 3 ends, this moment 1 output HIGH voltage, 7 ends just do not have signal output, not conducting of controllable silicon, the heating circuit is not worked, thereby reaches temperature auto control.FS ₁Be Thermal Cutoffs, can play the effect of protection.When out of control or controllable silicon punctured in the mode of diode when control circuit, temperature just might exceed controlling value, at this moment, but just quick-break of fuse, thus circuit cut off, play the effect of holding circuit.

The utility model is simple in structure, and is easy to use, is the desirable specific purpose tool of hairdresser.
