The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail.

As depicted in figs. 1 and 2, health care heating cushion of the present utility model, the cotton layer 2 of pin that comprises two-layer rectangle, between the cotton layer 2 of two-layer pin, be provided with two-layer nonwoven layer 4, be placed with a plurality of linear heating wires 1 of Serpentis that U-shaped is interconnected to constitute end to end that are shaped as between the two-layer nonwoven layer 4, heating wire 1 adopts the fine heating wire of silica gel carbon, heating wire 1 is fixed on the non-woven fabrics 4 by car clothing suturing with thread management, be in series with two temperature controllers 5 at heating wire 1, temperature controller 5 is coated with pyrocondensation glued membrane 7 with the junction of heating wire 1, make it have good air-tightness, be respectively equipped with the PVC layer 3 of rectangle at the up and down two ends of the cotton layer 2 of pin, PVC layer 3, four limits between the cotton layer 2 of pin and the nonwoven layer 4 are carried out thermal welding by high frequency mould (the about 15mm of slot pitch) to it, and the cotton layer 2 of pin is bonded together with PCV layer 3 and nonwoven layer 4.

As shown in Figure 3, the surface of PVC layer 3 is provided with the rectangular channel 6 by the high frequency hot melt, the two ends of rectangular channel 6 have arc, this rectangular channel 6 be rectangular array with 5 row, 21 column distributions on PVC layer 3, the length of rectangular channel 6 is that 19.5mm, width are 3mm, col width between two rectangular channels 6 is 15mm, and line-spacing is 32mm.

As shown in Figure 4, temperature controller 5 is coated with respectively pyrocondensation glued membrane 7 with the junction of heating wire 1, and pyrocondensation glued membrane 7 is bonding by glue for heat-shrink tube, even in water, circuit part also can work.

Temperature raises after heating wire 1 energising, temperature controller 5 temperature also increase, when the rising of temperature controller 5 temperature reaches its cut off value, temperature controller 5 interior metal shell fragments are flicked by make position, cut off circuit, heating wire 1 is stopped heating immediately, when temperature controller 5 temperature progressively drop to its closing value, temperature controller 5 interior metal shell fragments automatically reset to make position by open position again, circuit turn-on, heating wire 1 heats immediately, thereby product temperature is controlled within the set point, plays overheated, overcurrent protection; The weight of the cotton layer 2 of the pin of nonwoven layer 4 outside upper and lower surfaces is that 100g is thick, makes whole heating main body feel soft, and sense next to the skin well during use.Pin cotton layer 2 is done welding with PVC layer 3 usefulness high frequency mould to the cotton layer 2 of pin, PVC layer 3 and nonwoven layer 4 unifications, has both guaranteed air-tightness and the safety of heating main body outer surface, again whole heating main body tightly is fixed together.Sense next to the skin is better during use, and more sense is evenly for the heating of PVC layer 3 outer surface.

Because the high temperature resistant silica gel carbon fiber exothermic wire 1 of high-tech that uses low-carbon environment-friendly is made pyrotoxin, make whole product X ray penetration power stronger, its far infrared emissivity is more than 3 times of metal heating wire, whole product far infrared normal emittance is up to 86%, be applicable to the auxiliary analgesia of the pain that chronic soft tissue injuries, strain and arthroxerosis disease etc. cause, pure physics analgesia, without any side effects.
