The upper of conventional shoes has a certain breathability, and air circulation is carried out through the upper, but the air circulation speed is slow, and the circulation of air in the shoe cavity cannot be effectively solved. Therefore, breathable soles appear on the market, and heel air bags are arranged at the heel of the sole, and the heel air bag is transmitted to other positions of the shoe body through the air pipe, but the use degree of the air bag of this sole is limited, and the air bag is vertically forced during walking, and the heel air bag is limited by the air bag placement groove, so only part of the area of the air bag can be pressed, and the air in the air bag cannot be fully utilized. Secondly, the heel air bag is transmitted to the forefoot or other positions through the air pipe, and since the sole is a relatively closed space, rapid circulation cannot be formed, which affects the transmission speed of the air pipe and the air permeation effect. At the same time, the air transmitted from the air pipe to the forefoot or other positions is transmitted into the shoe cavity through the air holes of the insole, and then discharged by the upper, so the air circulation speed is slow, which affects the air permeation effect.

[0024] Referring to Figures 1-5 The utility model discloses a kind of breathable outer circulation air bag shoe sole, including shoe sole body 1, the shoe sole body 1 upper end portion has heel groove 11 and forefoot groove 12, and the shoe sole body is provided with through hole 13 passing through shoe sole body, the through hole 13 is covered with polyurethane waterproof breathable membrane 5. The shoe sole forefoot is provided with front air bag 2, front air bag 2 is placed in forefoot groove 12, the shoe sole heel is provided with rear air bag 3, rear air bag 3 is placed in heel groove 11, and front air bag 2 and rear air bag 3 are connected by air inlet passage 4. Among them, front air bag 2 and rear air bag 3 are preferably elliptical structure, the diameter of front air bag 2 is greater than the diameter of rear air bag 3, the height of front air bag 2 is less than the height of rear air bag 3, the height of front air bag 2 is compatible with the height of insole forefoot inner chamber, and rear air bag is compatible with the height of shoe sole heel. Specifically, the rear air bag 3 has air inlet pipe 31 and air outlet end 32, wherein the air outlet end 32 is air outlet port or air outlet pipe. The shoe sole body heel side wall has groove hole 14 adapted to air inlet pipe, and air inlet pipe 31 is installed in groove hole 14. One-way air inlet valve 33 and polyurethane waterproof breathable membrane 5 are provided in the air inlet pipe 31, the air outlet end 32 is connected with the air inlet of air inlet passage 4, the air outlet of air inlet passage 4 is connected with the air inlet end of front air bag 2, and the end of front air bag 2 in contact with insole has a plurality of air bag air holes 21.
[0025] During walking or running, the heel and the forefoot of the foot alternately touch the ground, which drives the rear air bag and the front air bag to be alternately squeezed. The rear air bag 3 inhales fresh air from the outside through the air inlet pipe. When the heel touches the ground and squeezes the rear air bag 3, the rear air bag transmits the fresh air to the front air bag 2 through the air inlet channel 4. During the transmission of fresh air in the air inlet channel 4, the air in the inner cavity of the front air bag 2 is filled, and the excess air is discharged in turn through the air permeable hole 21 and the through hole 13. Based on the principle of air pressure difference, the air inlet speed of the air inlet channel is accelerated, so that the rear air bag quickly rebounds and resets. During the rebounding and resetting of the rear air bag, fresh air is quickly inhaled through the air inlet pipe, which improves the comfort of wearing and accelerates the speed of the rear air bag inhaling fresh air. When the front air bag 2 is squeezed, the air in the front air bag is transmitted to the shoe cavity through the air permeable hole 21 and the air permeable hole of the insole. The squeezing of the front air bag 2 enhances the speed and quantity of fresh air entering the shoe cavity, ensuring that more air enters the shoe cavity. When the gas in the shoe cavity reaches a certain density, the turbid gas in the shoe body is output to the outside of the shoe body through the through hole of the sole, realizing the internal and external circulation of air.
[0026] Further, the upper end of the sole body 1 is provided with an insole 6, and the insole has a plurality of insole air permeable holes 61. The positions of the air permeable holes 61 are preferably set at positions corresponding to the forefoot air bag or the air permeable holes are uniformly distributed on the entire insole. The lower end surface of the insole is provided with a rear protrusion 62 at the heel, and is provided with a front protrusion 63 at the forefoot. The front protrusion 63 has a plurality of protrusion air permeable holes 64 in communication with the insole air permeable holes 61. The insole 6 is placed on the upper end of the sole body, the rear protrusion 62 of the insole abuts against the rear air bag 3, and the front protrusion 63 of the insole abuts against the front air bag 2. During walking, the front and rear protrusions are used in cooperation with the front and rear air bags. The protrusions increase the squeezing range of the air bags. The rear protrusion 62 is used in cooperation with the rear air bag 3 to squeeze the fresh air in the rear air bag to the front air bag to the maximum extent. The front protrusion 63 is used in cooperation with the front air bag 2 to transmit the fresh air in the front air bag 2 to the shoe cavity to the maximum extent through the insole air permeable holes. After the front and rear protrusions are used in cooperation with the front and rear air bags to discharge the gas in the front and rear air bags to the maximum extent, the front and rear air bags rebound at a relatively high speed during resetting, so that the front air bag or the rear air bag is replenished with gas more timely and quickly, and the air circulation in the entire sole is more smooth. At the same time, when the protrusions of the insole bottom squeeze the corresponding air bags, the protrusion parts fill the sunken grooves caused by the squeezing of the air bags, thereby improving the comfort of wearing.
[0027] Further, the air inlet channel preferably has two structures, specifically including: 1. The air inlet channel 4 is a Tesla valve structure. The air inlet end of the Tesla valve structure is connected with the air outlet end of the rear air bag, and the air outlet end of the Tesla valve structure is connected with the air inlet end of the front air bag (see Figure 1 2. The air inlet channel 4 includes an air inlet pipe, and a one-way air inlet valve is arranged in the air inlet pipe. The one-way air inlet valve realizes one-way air inlet from the rear air bag to the front air bag, preventing the air from flowing back after the front air bag is squeezed (see Figure 2as shown).
