Abstract

The utility model discloses an electric heating pad for warming which is composed of an outer decorative protecting layer, an insulating layer and a heating layer, and relates to the technical field of daily necessities. The utility model can be used as a seat cushion for people to prevent cold in winter or other daily articles, which has the advantages of stable heat energy, big heat capacity, high heat efficiency, convenient manufacture and low cost.

Description

Electric heating pad for warming

The utility model Electric heating pad for warming relates to the daily necessities technical field, is applicable to people's winter protection in winter seat cushion or as commodity.

At present domestic have electric blanket for people's warming, form by cloth, resistance wire and mains switch, its weak point is the manufacturing technique requirent height, it is inhomogeneous that the resistance wire local pyrexia exists thermal source, unsettled phenomenon, simultaneously, general only as bedding, can not use as seat cushion, it is narrow to exist range of application, problem of ultra-high price.

The purpose of this utility model provides a kind of Electric heating pad for warming, use this Electric heating pad for warming can reach thermal source evenly, stable, price is low, the purpose of winter protection in winter.

The design of the utility model Electric heating pad for warming (Fig. 1～2) is made up of outer decoration protective layer (1) insulating barrier (2), heating layer (3), mains switch (4).It is that heating layer (3) is done basic unit with the nylon cloth of heatproof more than 120 ℃ that its structure connects, coated with conductive coating constitutes in the above, electrode is made on the both sides of heating layer (3), and on electrode, the mains switch (4) that is connected the band plug is then gone up formation with wire bonds.Insulating barrier (2) adopts and meets national electrical insulating material, and the insulation temperature resistant grade is that the cloth of E level is made on the upper and lower layer of heating layer (3).The upper and lower layer that outer decoration protective layer (1) adopts continuous synthetic fibre blending cloth to make at insulating barrier (2) upward constitutes Electric heating pad for warming.

The effect of the utility model Electric heating pad for warming is compared with prior art: 1, because the pyrotoxin of heating layer is to adopt electrically-conducting paint, have the advantage that thermal source is stable, heat is big, the heat efficiency is high; 2, therefore easy to make owing to select for use cloth to make matrix, it is low and use light effect to have a cost.

Fig. 1 is the cross-section structure of the utility model Electric heating pad for warming;

Fig. 2 is the shape assumption diagram of Fig. 1.

The embodiment of the utility model Electric heating pad for warming is to be example to produce an Electric heating pad for warming, select the nylon cloth of a 420 * 420mm of 120 ℃ of commercially available heatproofs for use, and the heating electrically-conducting paint of 260 * 260mm is made in coating thereon, this coating is for being mixed with certainly, require to apply evenly, certain thickness is arranged.Adopt metal electrode film to be sewn to sewing machine on the both sides of heating layer (3), lead one end is welded on the electrode slice, and the other end is welded on 220V, on the hand switch of 1A50Hg (4), and the other end plug of switch.Select two of commercially available insulated nylon cloth 420 * 420mm for use, use stitching sewing machine on the upper and lower layer of heating layer (3).Select the continuous synthetic fibre cloth of colored shape 420 * 420mm for use two, make equally to go up and constitute Electric heating pad for warming at the upper and lower layer of insulating barrier (2).

Claims

1, a kind of Electric heating pad for warming; form by cloth, mains switch; it is characterized in that scribbling electrically-conducting paint on the heating layer (3); metal electrode is made on the both sides of heating layer (3); wire bonds is on electrode and mains switch (4); insulating barrier (2) is made on the upper and lower layer of heating layer (3), decorates protective layer (1) outward and makes formation on the upper and lower layer of insulating barrier (2).
