Abstract

The utility model discloses electrothermal warm clothing which has the key point that a control circuit is composed of a power supply Vcc, a crystal oscillator Z, an integrated block IC, a micro temperature controller and a high-frequency power switch tube Q. The crystal oscillator Z generates pulses with fixed frequency, after being amplified in the integrated block IC, the pulses are supplied to the high-frequency power switch tube Q by a capacitor, and the power of the high-frequency power switch tube Q is supplied by a resistance through an electric heating wire. According to the temperature needed by a human body, the electric heating wire is fixed at constant temperature of 38 DEG C, the micro temperature controller is installed in a warm clothing interlayer at a temperature sensitive position of a body skin adjusting the temperature automatically according to practical environment. The electrothermal warm clothing adopts a high-capacity lithium battery with the aging of 8 to 12 hours to supply power, can be connected with a vehicle by a convenient line for convenience and rapidness, and adopts the high-frequency power switch tube having the advantages of safety, electricity conservation, comfort, free movement and long service life. The electrothermal warm clothing is particularly suitable for the use of arthritis patients, rheumatism patients, persons having disability on legs and people working under the special environment.

Description

A kind of electrothermal clothes

One, technical field

The utility model relates to a kind of clothes by electric heating.

Two, background technology

Due to limited conditions, a lot of places also do not have heating installation, perhaps because of individual factor, as the handicapped crowd of leg, arthritis, rheumatisant etc., some crowd who under particular surroundings, works in addition, as the traffic police who stands guard, frontier guard, postman by motorcycle etc., cold of shank, the particularly crowd who under particular surroundings, works be can feel especially, may arthritis, rheumatism etc. be suffered from because of under the environment of cold, working for a long time.

Three, summary of the invention

The technical problems to be solved in the utility model is: design a kind of electrothermal clothes, provide the energy with the rechargable power supplies of carrying for warm-up, can effectively address the above problem.

The technical scheme that solution the utility model technical problem is taked is: an interlayer is established in daily cotton docile nearly inboard of wearing, be arranged in the interlayer heating wire also fixing, controller and charging plug can be located on the waist of trousers or the inboard, base of upper garment, heating wire can and be feared cold spots density different distributions at each position of whole body according to head-on wind, back side wind, also only branch shank or the shoulder back.Its key is: add thermal control and finished by control circuit and heating wire, control circuit is by rechargable power supplies Vcc, crystal oscillator Z, ic chip, minisize temperature controller R6, high frequency power switching tube Q forms, crystal oscillator Z one end connects 11 pin, the one termination power negative pole of ic chip, 12 pin, the one termination power negative pole of minisize temperature controller R6 one termination ic chip, 10 foot meridian capacitor C2 of ic chip connects the control utmost point of high frequency power switching tube Q, heating wire one end connects positive source through resistance R 7, the source electrode of one termination, the drain electrode of high frequency power switching tube Q connects the negative pole of power supply; With minisize temperature controller R6 be installed in the interlayer, body skin temperature-sensitive sensitive part.

In order to be applicable to the power supply in the direct use electric motor car, the rechargable power supplies Vcc of control circuit connects a mu balanced circuit through a diode, has an interpolation type plug on the mu balanced circuit, can be used for being connected with the storage battery of electric motor car.

Good effect of the present utility model is: when indoor use, can power by external power, and give the lithium cell charging of carrying simultaneously; High power capacity lithium battery power supply then when going out by carrying, timeliness can reach 8-12 hour; Can be connected by convenient line with motor vehicle, convenient and swift; Can be according to variations in temperature to be temperature automatically controlled on the spot, warmth retention property is good, and safety and comfort and motion are freely; Adopt the high frequency power switching tube, safe and power saving, long service life.The crowd who is particularly suitable for arthritis, rheumatisant, the handicapped people of shank and works under particular surroundings uses.

Four, description of drawings

Accompanying drawing is the connection diagram of electric principle of the present utility model and heating wire.

Five, the specific embodiment

With the heat insulation trousers is example, to make of Thermal-insulating pile cloth in the trousers of the daily cotton-padded trousers of wearing, an interlayer is established in the inboard in the trousers of shank, the heating wire standard is arranged and is fixed in the interlayer, knee position, front heating wire density is big slightly, back heating wire density is smaller slightly, and controller and charging plug are located on the waist of trousers, with minisize temperature controller be installed in the interlayer, shank inside skin responsive to temperature position.

As shown in drawings, of the present utility modelly add thermal control by a mu balanced circuit 1, control circuit 2 and heating wire 3 are finished, control circuit 2 is by rechargable power supplies Vcc, crystal oscillator Z, ic chip, minisize temperature controller R6, high frequency power switching tube Q forms, crystal oscillator Z one end connects 11 pin of ic chip, one termination power negative pole, 12 pin, the one termination power negative pole of minisize temperature controller R6 one termination ic chip, 10 foot meridian capacitor C2 of ic chip connects the control utmost point of high frequency power switching tube Q, heating wire 3 one ends connect positive source through resistance R 7, the source electrode of one termination high frequency power switching tube Q, the drain electrode of high frequency power switching tube Q connects the negative pole of power supply.The interpolation type plug is through 1 pin of a diode D1 connection ic chip, and output pin 6 pin of ic chip connect the rechargable power supplies Vcc of control circuit 2 through a diode D2.

When using electric vehicle power sources, the interpolation type plug that has on the mu balanced circuit 1 is connected with the power supply of electric motor car, voltage is confirmed the 1 pin power supply of diode D1, ic chip through polarity, dividing potential drop gives the 2-5 pin of IC to confirm voltage, make the constant 11.5V voltage of 6 pin output of ic chip, and the 9 pin power supply of giving ic chip through diode D2; Crystal oscillator Z produces the pulse of fixed frequency, and after the inner amplification of ic chip, by capacitor C 5 supply high frequency power switch pipe Q, the power supply of high frequency power switching tube Q is supplied with through heating wire 3 by resistance R 7.According to the needed by human body temperature, at 38 ℃, minisize temperature controller R6 can regulate temperature automatically according to actual environment with heating wire 3 constant temperature.Electric vehicle power sources is the rechargable power supplies Vcc charging of control circuit 2 through diode D2 simultaneously.

During no external application power supply, control circuit 2 is by rechargable power supplies Vcc power supply, and reason diode D2 isolates, and preceding mu balanced circuit 1 is not worked, and has only control circuit 2 work of back.
