FIELD OF THE INVENTION [0001] The present invention relates to insoles, and particular to an air-ventilating insole, wherein a plurality of spiral springs are distributed in an air chamber between an upper insole and a lower insole so as to have a preferred stability. Thereby, the insole has preferred arrangement of the air ventilating holes so that the shoe with the insole of the present invention can have preferred air ventilation effect. BACKGROUND OF THE INVENTION [0002] In the prior art shoe with air ventilating function has pumps or airbags or check valves or air guide tubes, etc. in the sole of the shoe for controlling air to flow unidirectionally. Since these devices have a larger volume, if they are installed in a shoe, other than the strength of the shoe being reduced, the user will feel uneasy. Thereby, the shoe cannot be washed in water. [0003] To improve above mentioned defects, in U.S. patent Ser. No. 10/647,571, assigned to the inventor of the present invention, an air-ventilating insole is developed which can be placed in a shoe so as to have a preferred effect with a lower cost. In the prior arts, a plurality of spiral springs with smaller size are used. In the prior art, the spiral springs have a lateral round positioning ends. No positioning slots is formed. Thereby, the spiral springs will swing and vibrate so as to affect the air exchange function. Furthermore, the adhering structure by the upper insole, lower insole, and rubber strips to form an air chamber is easy to detach or destroyed so that air vents out. SUMMARY OF THE INVENTION [0004] Accordingly, the primary object of the present invention is to provide an air-ventilating insole, wherein the air outlets face upwards. It can be used in cold weather. If it is cold or no ventilation effect is necessary, the insole can be upside down and the left insole is exchanged with the right insole so that the air outlets face downward. As a result air in the air chamber is hindered in the air chamber. Thus the air chamber is used as an air inflation pad which has the effect of softness and protection. [0005] To achieve above objects, the present invention provides an air-ventilating insole comprises an upper insole; a center of the upper insole being formed with a receiving groove; an enclosing frame enclosing the receiving groove; a plurality of U shape positioning slots being formed on the enclosing frame; a heel portion of the upper insole being formed with a plurality of air inlets and a front thenar portion of the upper insole being formed with a plurality of air outlets; a lower insole located below the upper insole; an air chamber being formed; a plurality of spiral springs installed between the upper insole and lower insole; the spiral springs being installed to the U shape positioning slots of the enclosing frame; each spiral spring being formed as a truncated cone and further as the spiral spring is compressed to be on a same plane; one end of the spiral spring being formed with a U shape positioning end which is embedded into a respective U shape positioning slot of the upper insole; a ventilating layer stuck above the upper insole at a position for contacting the bottom of the leg; a plurality of air input holes being formed in the ventilating layer, which are communicated to the air inlets. When the heel presses upon the insoles, the air inlets of the upper insole and the air input holes of the ventilating layer will compress air in the air chamber so as to flow upward to the front thenar portion of the user's leg. [0006] Moreover, in the present invention, if it is cold or no ventilation effect is necessary, the insole can be upside down and the left insole is exchanged with the right insole so that the air outlets face downward. As a result air in the air chamber is hindered in the air chamber. Thus the air chamber is used as an air inflation pad which has the effect of softness and protection. [0007] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing. BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 is an exploded perspective view of the present invention. [0009] FIG. 2 is an assembled perspective view of the present invention. [0010] FIG. 3 is a plane schematic view of the present invention showing the treading operation of the present invention. [0011] FIG. 4 is a plane cross section view showing the state that the leg is left from ground. [0012] FIG. 5 shows the second embodiment of the present invention. [0013] FIG. 6 shows the third embodiment of the present invention. [0014] FIG. 7 shows one application of the present invention. DETAILED DESCRIPTION OF THE INVENTION [0015] In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. [0016] Referring to FIGS. 1 and 2, the structure of the present invention is illustrated. The insole 1 of present invention includes the following elements. [0017] An upper insole 11 is included. A center of the upper insole 11 is formed with a receiving groove 111. An enclosing frame 112 encloses the receiving groove 111. A plurality of U shape positioning slots 113 are formed on the enclosing frame 112. A heel portion of the upper insole 11 is formed with a plurality of air inlets 114 and a front thenar portion of the upper insole 11 is formed with a plurality of air outlets 115 [0018] A lower insole 12 is located below the upper insole 11. An air chamber S is formed by the upper insole 11 and lower insole 12. [0019] A plurality of spiral springs 14 are installed between the upper insole 11 and lower insole 12. The spiral springs 14 are installed to the U shape positioning slots 113 of the enclosing frame 112. Each spiral spring 14 has an upper plane and a lower plane a plurality of coils are wound between the upper plane and a lower plane. Thereby, the spiral spring 14 are formed as a truncated cone and further the spiral spring 14 can be compressed to be on a same plane. One end of the spiral spring 14 is formed with a U shape positioning end 141 which is embedded into a respective U shape positioning slot 113 of the upper insole 11 as the upper insole 11 and the lower insole 12 are adhered together. Thereby, the U shape positioning end 141 can be used to position the orientation of the spiral spring 14 so as to have the effect of enhancing the structure of the insole. Continue reading...
