For achieving the above object, the utility model Electric heating kneecap, comprise knee-pad body and controller, it is characterized in that the knee-pad body has internal layer, the structure of skin and interlayer, interlayer is the lining that individual layer contains the yarn that generates heat, described heating yarn is formed with one or more heater in lining, be interconnected with one another formation series connection and/or parallel circuit by the extension of heating yarn between the heater, the two ends of described circuit electric energy input are respectively equipped with terminals, adjacent at two terminals is provided with a pocket, put a controller in the pocket, controller and two terminals are connected to form a loop.

Described heating yarn is to be wound in outside natural and/or the chemical fibre yarn by a kind of silk in silver, copper, nickel, chromium, molybdenum, aluminium, tin or the tungsten of diameter 0.02mm-0.09mm, and its resistance value is 0.5 Ω/m-150 Ω/m.

Described heater is along the horizontal continuous weaving of interlayer cloth cover by the heating yarn, and inweave the conventional yarn of some lines between every adjacent heating yarn, the heating yarn is knitted to the heater two ends and is come and gone serial connection formation rectangle, prismatic, circle, ellipse or square a kind of geometry with folding U limit form, and its area is less than 250cm ²

Described controller is to be electrically connected with power management module and control circuit for pulse-width modulation successively by the polymer rechargeable battery to be installed in the box, power interface, connecting line, function key and LED with the corresponding connection of circuit in the box are set on box, and its output voltage is 3.7V-24V.

Described function key comprises heat-flash key, weak hot key, low-grade fever key, warming key and startup and close key.

After adopting technique scheme, advantage of the present utility model and good effect are, form heater because the heating yarn directly inweaves in the knee-pad interlayer, make heater and interior folder combine together, the quality softness, no foreign body sensation, but dress multi-direction bending and extension, moisture absorption is ventilative, can not only in cold environment, continue for a long time initiatively to heat to heat, stop rheumatism cold air to be invaded, by the regulatory function key, make the temperature of knee keep weighing apparatus fixed, build the cosy impression of knee, thereby stimulate circulation, improve kneed nutrition supply, help health, and manufacture craft is simple, and anti-bending is anti-rubs, and easily goes into water washing, durable in use, the practicality height.
