People have developed and have utilized the ceramic electric heating diaphragm as heater for this reason, this material has efficiently, environmental protection, heat efficiency advantages of higher, as shown in Figure 2, be existing heating collar 7, this heating collar 7 is made up of two box-like sleeves, six prismatic shells 8, composite heat shield 9, ceramic heating element layer 10, metal heat-conducting layer 11, high temperature heat conducting coating 12, retaining mechanism 13 and external connection seat 14; Two box-like sleeves are to be semicircle in two, outer is the chunk (71,72) of triangular prism shell, chunk (71,72) internal layer is a metal heat-conducting layer 11, and on the inner surface of metal heat-conducting layer 11, be coated with high temperature heat conducting coating 12, metal heat-conducting layer 11 outer semicircle are surrounded by ceramic heating element layer 10, ceramic heating element layer 10 outer semicircle are surrounded by composite heat shield 9, outside the composite heat shield 9 is the triangular prism shell, and chunk (71,72) docking port outside joint is provided with retaining mechanism 13 and external connection seat 14; Described ceramic heating element layer 10 is to be serially connected through electric cocainine by several conventional ceramic sheets 101, constitute ceramic heating element layer 10, as described in Figure 6, be the tiling expansion schematic diagram of ceramic heating element layer 10, the structural disadvantages of this ceramic heating element layer 10 is that these conventional ceramic sheet 10 thermal conversion efficiencies are low, power loss is big.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned structural disadvantages, and a kind of thermal conversion efficiency height, a kind of novel energy-conserving heating collar that power loss is little are provided.

The utility model is to be achieved through the following technical solutions: a kind of novel energy-conserving heating collar, form by two box-like sleeves, six prismatic shells, composite heat shield, ceramic heating element layer, metal heat-conducting layer, high temperature heat conducting coating, retaining mechanism and external connection seat; Two box-like sleeves are for semicircle, be the chunk of triangular prism shell outward in two, the chunk internal layer is the metal heat-conducting layer, and on the inner surface of metal heat-conducting layer, be coated with the high temperature heat conducting coating, the outer semicircle of metal heat-conducting layer is surrounded by the ceramic heating element layer, the outer semicircle of ceramic heating element layer is surrounded by composite heat shield, composite heat shield is outward the triangular prism shell, and chunk docking port outside joint is provided with retaining mechanism and external connection seat;

Of the present utility model being characterised in that: the ceramic heating element layer is to be serially connected through electric cocainine by some single ceramic sheets, and the surface of this potsherd is provided with several through holes;

The utility model compared with prior art, beneficial effect is, by on some single ceramic sheets of ceramic heating element, having additional several through holes, thereby can make thermal conversion rate up to more than 98%, and there is not any power loss, adopt the ceramic heating element of the utility model structure, the fast any exothermic material after in the market of its programming rate can reach 800 ℃ of maximum temperatures after tested within 45 seconds.
