Detailed Description

The following describes embodiments of the present invention in detail with reference to the drawings and examples.

As shown in fig. 1, a breathable waterproof sole comprises an anti-skid outsole 4 and a midsole 9, wherein the midsole 9 is annular, an upper breathable waterproof layer 1 and a lower breathable waterproof layer 2 are respectively arranged on the upper surface and the lower surface of the midsole 9, so that a cavity is formed in the midsole 9, and the anti-skid outsole 4 is positioned below the lower breathable waterproof layer 2. An air bag breathable interlayer 3 is arranged in the cavity, the outer side wall of the air bag breathable interlayer 3 is attached to the inner side wall of the insole 9, and the upper surface and the lower surface of the air bag breathable interlayer are respectively contacted with the upper breathable waterproof layer 1 and the lower breathable waterproof layer 2.

As shown in fig. 2, the air-bag breathable interlayer 3 is sandwiched and wrapped between the upper breathable waterproof layer 1 and the lower breathable waterproof layer 2, and the whole air-bag breathable interlayer 3 is wrapped inside.

As shown in fig. 3 and 4, the air bag ventilation interlayer 3 comprises two air bags 7, the two air bags 7 are respectively arranged on the front palm part and the back palm part, and the two air bags 7 are communicated with each other through a connecting hole 5 along the foot length direction. The side of encircleing gasbag 7 is provided with foamed rubber 8, and foamed rubber 8 is located the medial surface of insole 9, and a plurality of poroid passageways 6 run through the side of foamed rubber 8 and insole 9, with gasbag 7 and external intercommunication.

Gasbag 7 is elastic material, the inside and outside is made by calendering rubber, constitute by flexible netted material between the inside and outside, itself have certain surface with last waterproof ventilative layer 1 contact be equipped with waterproof ventilative micropore, can realize shrink and kick-back and the external world carries out gas exchange, the gasbag inner chamber is provided with the elastic rubber gasbag support column 17 that is provided with a plurality of vertical directions, in order to realize bearing function and prevent because the gasbag repeated compression rebound performance deterioration after kick-backing. The thickness of the air bag wall is not more than 3mm, namely, only one layer of air-permeable waterproof membrane is arranged on the contact part of the air-permeable waterproof layer 1 and the air bag 7. The foamed rubber 8 wrapped outside plays a role in maintaining the structure of the whole air-permeable interlayer 3 of the air bag, and has good elasticity and plasticity. The foamed rubber 8 can also play a good load-bearing function.

As shown in fig. 5, both sides 10 of the anti-skid outsole 4 and the front tip 11 of the outsole have an empennage protection airbag sandwich structure to prevent deformation and damage to the airbag 7, thereby ensuring the support of the airbag structure.

As shown in figure 6, the antiskid outsole 4 is divided into several pieces, the heel 12 adopts wavy patterns, the front tip 13 and the central fossa part 14 adopt small geometrical triangular bulges which are uniformly arranged, and the two sides 15 of the front end adopt irregular large patterns. Secondly, a plurality of lines 16 are inserted into the sole part, and the lines can be bent and stretched in the walking process of a human body, so that mud is prevented from being brought, the wearing is more comfortable, the requirements of skid resistance of different parts are met respectively, the weight of the sole can be reduced at the line clearance part, and the effects of light weight and wearing resistance are achieved.

The utility model discloses in, including the ventilative intermediate layer 3 parcel of gasbag, gasbag 7 itself has elasticity, and lifting of people's foot falls down, presses or forms the linker with the external world during gassing 7, and humid hot gas circulates and exchanges with fresh gas around going on through the gasbag shrink. The concrete steps do, when the people's foot fell down, the last ventilative waterproof layer 1 of insole arranges moist heat gas to the shoes insole gasbag ventilative intermediate layer 3's structure, gets into in the gasbag 7 promptly, then passes through 9 lateral walls in the insole outside by the poroid passageway 6 of shoes both sides again, can let the discharge that sweat gas accelerates like this, has promoted the dry and comfortable degree in the shoes greatly to owing to used waterproof ventilative surface fabric, the waterproof performance of sole has also ensured. When the foot of a person is lifted, fresh air enters the sole from the porous channel 6, so that the exchange of air inside and outside the shoe is realized, and the air inside the shoe is ensured to be dry. The air bag 7 is an important component of the air bag breathable interlayer 3, and mainly depends on the expansion and contraction of the air bag 7 to exchange air with the outside, and the air flow direction is shown in figure 4. When the air bag is not worn, the air bag 7 maintains the original shape, and because the calendered rubber structure and the flexible net-shaped material between the surface and the inner surface have good elastic plasticity, the stable state of air in the inner cavity of the air bag 7 is maintained when the air bag is not extruded by external force, and only in the walking process, the air bag is deformed and reset to exchange air with the outside through the pressure extrusion of human feet.

To sum up, the utility model discloses when having solved the sole ventilative, also reached waterproof effect to compare with present bleeder vent structure, gasbag simple structure easily realizes, can comparatively effectual realization shoes inner chamber damp and hot air and the convection current of external fresh air through its self shrink and recovery, and is comfortable and easy to wear, possesses anti-skidding function simultaneously, experiences and feels good.

The utility model discloses the design that the gasbag structure can also be retrencied and retrench more retrencied, for example reduce the gasbag area and be a plurality of with the gasbag according to sole pressure distribution, communicate again, fall through lifting of people's foot and make the gasbag receive to rise to carry out with the exchange between the external gas.
