Abstract
The utility model relates to an automatic temperature control electrically heated suit, which comprises a faceshield, a sandwich, and an inner layer. The inner layer is provided with a heating resistance wire and an automatic temperature device. The automatic temperature device comprises a negative temperature critesister, an operational amplifier, and a drive three electrode tube. The utility model not only heats by utilizing the electric power, but also keeps a constant temperature, and the wearing is comfortable and convenient.
Description
Technical field:
The utility model belongs to human daily living article technical field, relates in particular to a kind of battery that utilizes and is the resistance wire in the energy heated clothing, makes it produce the clothes of heat.
Technical background:
The clothes that linings such as tradition cloth cotton or chemical fibre are made though the resisting cold thermal effect is arranged, self can not generate heat, and in the winter of severe cold, endures cold for preventing health, can only wear thicker cotton dress, and action is inconvenient.Though the cold-proof underwear weight after the improvement is light, heat insulation effect is better, sucting wet air permeability is relatively poor, wears uncomfortable.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the deficiency that conventional garments only has thermal effect, and a kind of convenience comfortable and easy to wear is provided, and can produce heat, and can prevent too high or too low for temperature, the automatic temperature-controlled electric heating clothes of saves energy.
The utility model is made up of face shield 1, interlayer 2 and internal layer 3, is provided with the resistive heater 4 that is connected with battery, switch in the interlayer 2.Resistive heater 4 can be symmetrical set at the anterior part of chest of clothes and back.
The utility model utilizes the battery heating, the temperature control equipment that is provided with resistive heater and forms in the interlayer by negative tempperature coefficient thermistor, operational amplifier etc., the energized resistive heater can produce heat, and can pass through temperature control equipment, the energized resistive heater can produce heat, and can regulate temperature, saves energy by temperature control equipment Y, in light weight, wear very convenient comfortable.
Description of drawings;
Accompanying drawing 1 is removed structural representation behind the outer cover for the utility model embodiment.
Accompanying drawing 2 is the utility model dress material cutaway view.
Accompanying drawing 3 is a temperature control equipment electrical schematic diagram of the present utility model.
Accompanying drawing 4 is No. four temperature control equipment electrical schematic diagrams of another embodiment of the utility model.
Embodiment:
Further describe the utility model structure and operation principle below in conjunction with embodiment.
Face shield 1 and internal layer 3 can be made with gentle matter cloth, and style can be decided interlayer 2 internal fixation resistive heater 4 and temperature control equipments according to each one hobby.
Referring to accompanying drawing 2, battery BT1 serial connection switch links to each other with the power positive end VCC of operational amplifier IC1 (LM324).Its negative terminal of operational amplifier IC1 is connected on the center of R5 (5.1K Ω) and R13 (5.1K Ω) series circuit, and the R5 other end links to each other with power supply VCC, and R13 other end ground connection makes the IC1 negative input end get 1/2VCC (negative terminal comparative voltage).R12 (5.1K Ω) and Rt1 (negative tempperature coefficient thermistor, normal temperature resistance are 5.1K Ω) series connection, its central point and operational amplifier IC1 anode join, as the anode comparative voltage.The Rt1 resistance is bigger when temperature is low, make the voltage of IC anode higher, when being higher than negative terminal comparative voltage 1/2VCC, IC1 exports high level, make BG1 (3DD15) saturation conduction by current-limiting resistance R9 (4.7K Ω), because heating resistance wire (R1=10 Ω-20 a Ω) end links to each other with the collector electrode that drives triode BG1, the other end links to each other by the anode of K switch with battery BT1, battery forms the loop, thereby can heat heating resistance wire R1 by K, R1, BG1 like this.Because Rt1 is near R1, the R1 heating descends the resistance of negative temperature coefficient Rt1, and IC1 positive input terminal voltage is descended, when dropping to IC1 load comparative voltage 1/2VCC, IC1 is output as 0, BG1 ends, and battery BT1 makes temperature descend not to the R1 heating so gradually, at this moment the Rt1 resistance raises, IC1 positive input terminal voltage rises, when surpassing negative terminal comparative voltage 1/2VCC, IC1 output HIGH voltage, at this moment BG1 is saturated again, battery to the R1 heating, goes round and begins again like this and carries out again, reaches temperature automatically controlled purpose.
Accompanying drawing 3 is another embodiment of the utility model, and heating resistor is symmetrical set four road attemperating unit electrical schematic diagrams at electric heating clothes chest and back part.
