DETAILED DESCRIPTION OF THE PRESENT INVENTION For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates. Referring to FIGS. 1, 2 and 3 , there is shown an improved structure of a hot packing comprising a plurality of hot packing bags 10 , 20 . The hot packing bags 10 , 12 contain sodium acetate solution 101 , 201 of self-heat emission, and iron plates 102 , 202 , and also only contains non-conductive liquid (for instance, water) or solid. The surface of the hot packing bags 10 , 20 are positioned with a plurality of thermal melting points 11 , 21 , such that the top and bottom surfaces of the bag body are combined at appropriate sections so as to avoid the contents within the bag body to accumulate at a specific area. The surrounding edge of a plurality of hot packing bags 10 , 20 connectedly sealed to form into another separate lamination layer for the mounting of electric heating plate 30 (for instance flexible membrane of carbon element). Thus, the heating plate 30 is not dipped within the hot packing bags 10 , 20 . The hot packing bags 10 , 20 can totally sealed and leakage proof. In addition, the wire 40 externally connected to the electric heating plate 30 passes through the sealed area of the two hot packing bags 10 , 20 . Thus, at the passage of the wire 40 is provided with a fastening ring 50 to provide the function of fastening and to entirely protect the hot packing bags 10 , 20 from damages as a result of the pulling of the wire 40 . The wire 40 is additionally connected with a timer 60 , a temperature regulator 70 so as to effectively control the heat emission of the electric heating plate 30 at a specific temperature so as to avoid excessive temperature to break the hot packing bags. Thus the hot packing bags 10 , 20 provide the function of heat packing treatment. Referring to FIG. 4 , the size of the electric heating plate 30 is substantially smaller than that of the hot packing bags 10 , 20 . The heat emission object 31 on the electric heating plate 30 is a loop shape. Thus, the heating plate 30 can provide heat evenly at every corner within the hot packing bags 10 , 20 . The electric heating plate 30 is provided with temperature control element 32 so as to sense the emitted temperature of the electric heating plate 30 so as to allow the user to control the electric heating plate 30 to a specific temperature so as to avoid excessive temperature of the heating plate 30 to break the hot packing bags 10 , 20 . In addition, the center of the electric heating plate 30 is provided with a through hole 33 . Thus, the top and bottom of the hot packing bags 10 , 20 are combined to each other at the through hole 33 by means of the heat melting points 11 , 21 . Referring to FIG. 5 , the surface of the timer 60 is provided with a rotating button 61 and the surrounding edge of the rotating button 61 has markings with various type of temperature control mode so that the heating plate 30 stops emitting heat after it has reached an appropriate time. With the supplement of the temperature regulator 70 , the present structure is a safe device and is electricity saving. Referring to FIGS. 6 and 7 , the electric heating plate 30 can be substituted with semiconductor cold/hot chip 80 . The semiconductor cold/hot chip 80 has a function one of a cold surface and a hot surface, and an extended regulating switch 81 is provided for switching function, such that the cold/hot surface can be interchanged. The surface of the cold/hot chip 80 is provided with temperature control element 801 to sense the temperature of the cold/hot chip 80 . Thus, by means of the operation of the temperature control button 82 , the cold/hot chip 80 will not produce excessive temperature, avoiding the melting of hot packing bags 10 , 20 . As can be seen from FIG. 7 , the top and bottom surface of the cold/hot chip 80 are located near to the hot packing bags 10 , 20 and are adhered with heat-reduction plate 83 to avoid the excessive heat from melting the hot packing bags 10 , 20 . In actual application, if sodium acetate solution within the hot packing bags 10 , 20 (any one) becomes crystallized state after utilization, the surface with heat energy produced by the cold/hot chip 80 will rapidly restore the hot packing bag, and the other cold surface of the cold/hot chip 80 will cause the hot packing back to provide cold packing effect Thus, the hot packing bags 10 , 20 have the rapid effect of restoration and cold/hot packing function. It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
