In addition, the descriptions related to "preferred", "less preferred", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

Example 1

Referring to fig. 1 and 2, the present embodiment provides a breathable sole, which includes a sole body 1, the sole body 1 includes a forefoot portion 11, an arch portion 12, and a rearfoot portion 13, a groove 131 is disposed on an upper surface of the rearfoot portion 13, an elastic airbag 2 is disposed in the groove 131, an air inlet/outlet 21 is disposed in a front portion of the elastic airbag 2, a main air groove 101 located in front of the air inlet/outlet 21 is disposed on the upper surface of the sole body 1, a rear end of the main air groove 101 is communicated with the groove 131, and a front end of the main air groove 101 extends to a front portion of the forefoot portion 11.

The elastic air bag 2 is made of elastic rubber, and can be integrally formed with the sole body 1 through injection molding or can be bonded together through an adhesive after being formed respectively.

When a user wears the shoe with the shoe body to walk, when the foot of the user falls to the ground, the heel of the foot of the user is stepped on the elastic air bag 2 to press out the air in the elastic air bag 2, the air flows to the forefoot along the main air groove 101, when the foot of the user is lifted, the heel of the foot of the user is lifted relative to the sole, at the moment, the elastic air bag 2 restores to the original shape under the action of the self elastic force, the external air is sucked into the elastic air bag 2, then the foot of the user falls to the ground again to press out … … the air in the elastic air bag 2, therefore, the elastic air bag 2 can be continuously inflated and deflated in the walking process of the user, the ventilating effect can be achieved, compared with the existing ventilating sole, holes do not need to be formed in the bottom surface and the side surface of the sole, and the waterproof performance is good.

Furthermore, the upper surface of forefoot portion 11 is provided with a plurality of left branch air grooves 102, one end of each left branch air groove 102 is connected to main air groove 101, and the other end extends toward the left side of sole body 1. The upper surface of forefoot portion 11 is provided with a plurality of right branch air grooves 103, one end of right branch air groove 103 is communicated with main air groove 101, and the other end extends toward the right side of sole body 1. By adopting the design, the air flow extruded by the elastic air bag 2 can circulate in most areas of the half sole of the foot of the user, and the ventilation effect is better.

The front part of the groove 131 is provided with a flow guide channel 104 which is gradually narrowed from back to front, the rear end of the main air groove 101 is directly communicated with the flow guide channel 104, and the air inlet and outlet 21 of the elastic air bag 2 faces the flow guide channel 104. The design of the flow guiding channel 104 can provide a better flow guiding effect, so that the air flow pressed out by the elastic air bag 2 can smoothly circulate along the main air groove 101.

Further, a limiting boss 132 is arranged in the groove 131, the top of the elastic airbag 2 is covered on the limiting boss 132, and the top of the elastic airbag 2 abuts against the limiting boss 132 when deforming downwards. The design of the limit boss 132 can improve the support of the sole part 13 of the foot to the sole of the user, and can limit the maximum downward deformation amplitude of the elastic air bag 2 and improve the reset speed of the elastic air bag 2.

Further, a gap 105 for deforming the elastic airbag 2 is left between the inner side wall of the groove 131 and the elastic airbag 2. Adopt such design, can reserve the space of deformation for elastic airbag 2, user's foot is stepped on elastic airbag 2, can avoid the inside wall extrusion elastic airbag 2's of recess 131 lateral wall and damage elastic airbag 2, is favorable to promoting elastic airbag 2's life.

Example 2

Fig. 3 shows embodiment 2 of the present invention, and this embodiment has a similar structure to embodiment 1, and the only difference is that: the upper surface of the elastic air bag is covered with a breathable net cloth 3 for shielding the air inlet and the air outlet.

The breathable net cloth 3 can play a role in skid resistance and can shield the air inlet and outlet, and bad phenomena such as foot damage, elastic air bag damage and the like caused by the fact that external sand and stone particles enter the elastic air bag 2 are prevented. The breathable net cloth 3 can adopt a structure similar to a mosquito net, and can reduce wind resistance as far as possible on the basis of blocking sand particles from entering the elastic air bag 2.

The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct or indirect application is included in other related technical fields in the patent protection scope of the present invention.
