Abstract

The utility model provides an electric heat textile, which comprises an electric heating device inside and also a controller, a switch, and a power supply which are electrically connected with an electrical heat device (1). A voltage fluctuation, which can induct electric heating devices, is arranged in the controller and modulated into carrier sampling devices and data analysis devices of the voltage signal. A switch controller (2) which can control the opening and closing of the switch according to the related voltage signal is also arranged in the controller. The product imposes electric heating device as a sensor element to induce the changes of the temperature, the pressure, the electricity or electric capacity when the body approach or leave, to bring voltage wave, and then modulate into a voltage signal via circuit so as to achieve the purpose of controlling the opening or closing of the switch automatically, and prevent the hidden dangers caused by continuing use after the departure, and moreover prevent the accident and save energy at the same time.

Description

A kind of electric heating yarn fabric

Technical field

The utility model relates to a kind of electric heating yarn fabric, i.e. various electric heating yarn fabrics such as Electric heating bed mattress, electric blanket or electric heating clothes.

Background technology

In the prior art, electric heating products such as various Electric heating bed mattresses, electric blanket or electric heating clothes by adopting hand switch, make the electrothermal device heating, thereby make similar electric heating products heating such as mattress, blanket or clothes, to satisfy the heating demand of people when the cold snap.Yet above-mentioned electric heating products is owing to adopt hand switch, and when not in use, the user usually can forget and turn off power supply, thereby has certain potential safety hazard, also wastes energy simultaneously.

The utility model content

But the purpose of this utility model is to provide a kind of automatic open close to prevent unexpected electric heating yarn fabric.

For achieving the above object, technical solution of the present utility model is: a kind of electric heating yarn fabric, and its inside is provided with electrothermal device, and it also is provided with controller, switch and power supply and is electrically connected with electrothermal device; But and in controller, be provided with the voltage fluctuation of Induction Heating device and it be modulated into the carrier wave sampler and the data analysis set-up of voltage signal, also being provided with can be according to above-mentioned voltage signal and on-off controller that control switch opens and closes.

Described electrothermal device is sheet metal, wire or heating wire.

After adopting such scheme, the utility model utilizes electrothermal device (as sheet metal, wire or heating wire etc.) itself as sensing element, the variation of temperature, pressure, electric charge or capacitance when the induction human body is toward or away from, and the generation voltage fluctuation, be modulated into voltage signal through oversampling circuit again, thereby reach the purpose of automatic control switch energising or outage, and prevent to continue the potential safety hazard that energising brings because of the user leaves the back, and then can avoid unexpected generation, but while energy savings.

Embodiment

Electric heating yarn fabric described in the utility model comprises various electric heating products such as Electric heating bed mattress, electric blanket or electric heating clothes, and as shown in Figure 1, 2, the utility model is that embodiment is illustrated with the electric blanket.

This electric heating products (being electric blanket 1) inside is provided with electrothermal device 2, and this electrothermal device 2 can be heatable elements such as sheet metal, wire or heating wire, and present embodiment is example with the heating wire.This electric blanket 1 also is provided with controller 3, switch 4 and power supply 5 and is electrically connected with electrothermal device 2, is provided with carrier wave sampler 6 and data analysis set-up 7 in controller 3, and also being provided with can be according to voltage signal and on-off controller 8 that control switch opens and closes.

Operation principle of the present utility model is: because electrothermal device 2 is (as sheet metal, wire or heating wire) when human body is toward or away from, even disconnect power supply, also can sense the temperature of human body, pressure, the variation of electric charge or capacitance, and the generation voltage fluctuation, the utility model can be taken a sample by 6 pairs of these voltage fluctuations of carrier wave sampler, carry out data analysis by data analysis set-up 7 again, and be modulated into voltage signal, this voltage signal can be by on-off controller 8 and the keying of control switch, thereby reaches automatic unlatching or close the effect of electric heating products.

In addition, described switch 4 also can be by the keying of manual control model control switch except that can controlling by above-mentioned automatic induction.

Cooperate shown in Figure 3ly again, the course of work of the present utility model is as follows:

One, human body induction function:

After human body signal receives through M, after triode Q4-9014 amplification, by C4Carry out clutter filtering, amplify by oscillator U1A again, U1B carries out value relatively, the square wave of output rule, pass to the P93 mouth of single-chip microcomputer 5840 then by isolation light lotus root, single-chip microcomputer inside is analyzed P93 mouth waveform, the state of control LED lamp, the state of control controllable silicon SCR 1 conducting and shutoff is realized heating and the not control of heated condition.

Two, temperature gear controlled function:

Utilize energising outage duty ratio relation that gear is set.Total time is set to 10S, regulates its conduction time, carries out the setting of temperature gear with power-off time.

Three, mechanical timer function:

By the selection of timing gear, single-chip microcomputer is judged, enters regularly 2H, 6H, 9H state.
