For example, patent application nos.: 201821830057.4 includes the non-woven fabrics basic unit, is fixed in resistance wire on the non-woven fabrics basic unit, connects in the controller of resistance wire, the resistance wire is made on the non-woven fabrics basic unit through the nylon wire, and the resistance wire is even crooked distribution, the controller includes casing, pyroelectric infrared sensor, delay switch circuit and light-emitting component, pyroelectric infrared sensor is located the surface of casing and responds to the human body and is close to and export sensing signal, and delay switch circuit connects and is used for receiving sensing signal and realize the instantaneous closure and the time delay disconnection of switch contact in pyroelectric infrared sensor, light-emitting component is controlled by delay switch circuit and realizes luminous suggestion, has reached the effect of convenient to use.

In view of the above-mentioned related art, the inventor believes that the heating wire of the device is not stable enough, may be broken off and damaged during use or washing, and the heating wire has large power, and the power circuit lacks a protection device during starting.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems, the utility model provides a safe and intelligent heating pad, which aims to solve the problems in the prior art.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides a safe and intelligent heating pad which comprises a silica gel sleeve and non-woven fabrics; install the power in the silica gel cover, the control panel is installed to silica gel cover outer wall, the control panel with power electric connection, the non-woven fabrics is equipped with the sewing line, install the heater in the non-woven fabrics, the temperature controller is installed to the heater, the heater runs through the non-woven fabrics and extend to the non-woven fabrics outer end and with silica gel cover fixed connection, the heater with power electric connection, NTC thermistor is installed to the power.

Adopt above-mentioned technical scheme, fix the heater in the non-woven fabrics through the sewing line, make the heater strip more firm, difficult not hard up drops, through this product of temperature controller energy-conservation more, safety and accurate accuse temperature, restrain too big electric current through NTC thermistor, protect its power supply circuit.

Preferably, the NTC thermistor penetrates through the silica gel sleeve and the non-woven fabric and extends into the non-woven fabric, and the heating wire is matched with the NTC thermistor.

By adopting the technical scheme, after the heating wire starts to work and generate heat through the design, the temperature is increased, the resistance of the NTC thermistor is reduced, and the normal work cannot be influenced.

The technical scheme has the following advantages or beneficial effects:

1. fix the heater in the non-woven fabrics through the sewing line, make the heater strip more firm, difficult not hard up drops, through this product of temperature controller energy-conservation more, safety and accurate accuse temperature, restrain too big electric current through NTC thermistor, protect its power supply circuit.
