Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a breathable sole. Background Art

[0002] Shoes are an indispensable daily necessity in people's daily life. The comfort of shoes depends not only on the soles that conform to human anatomy, but also on whether the shoes can discharge the water vapor generated by sweating in the shoes to avoid dampness, heat and bacteria breeding in the shoes. Most of the foot sweat in the shoes appears between the soles of the feet and the soles. The sweat here is difficult to evaporate and will gather on the insoles and insoles where the feet step. Existing shoes generally achieve ventilation through the design of upper fabrics and structures. The soles generally have poor air permeability, and the feet sweat and heat, which is easy to breed bacteria. Therefore, the utility model proposes a breathable sole with good air permeability. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model adopts such a technical scheme: a breathable sole, applied to shoes, comprising a midsole and an outsole arranged from top to bottom, the bottom of the midsole is provided with an air cavity at the heel position, the top of the air cavity is connected with a first air groove, the end of the first air groove is connected with two second air grooves, the two second air grooves are in a V-shaped structure facing the sole position; the ends of the two second air grooves are connected by a third air groove of an L-shaped structure, a plurality of cascaded fourth air grooves are provided on one side of the third air groove close to the toe position, the fourth air groove is a rhombus or rectangular structure with missing corners, and the top angles of the plurality of fourth air grooves are located on the longitudinal center line of the midsole; the two ends of the fourth air groove close to the third air groove are connected with the two ends of the third air groove, the two ends of the fourth air groove of the rear stage are connected with the fourth air groove of the front stage, and the fourth air groove located at the sole position is provided with a plurality of evenly distributed air holes; the air cavity is connected with a plurality of air vents connected with the outside.

[0005] Furthermore, the fourth air groove includes two branch air grooves in an eight-shaped structure; the outer ends of the two branch air grooves are connected by a connecting air groove in an L-shaped structure.

[0006] Furthermore, the bending point of each of the fourth air grooves connecting the air grooves is located on the longitudinal center line of the midsole.

[0007] Furthermore, the plurality of cascaded fourth air grooves are arranged from large to small in a direction toward the toes.

[0008] Furthermore, there are two ventilation ducts, which are respectively arranged at the rear end and the outer side of the heel of the midsole.

[0009] Furthermore, the structure of the air cavity is in the shape of a whale.

[0010] Beneficial Effects

[0011] Compared with the prior art, the utility model has at least the following advantages: a new type of ventilation system of the sole is formed by the whale-shaped air cavity, the first air groove, the second air groove, the third air groove and the fourth air groove, which effectively helps the circulation between the sole and the outside air and dissipates moisture and heat, has good ventilation performance, and makes the foot dry and comfortable. When walking, the sole is squeezed and bent, so that the air cavity and the air groove space are deformed, which speeds up the circulation of air. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to make the purpose, technical scheme and advantages of the utility model clearer, a detailed description is given below in conjunction with the accompanying drawings and specific implementation methods. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] See also Figure 1-Figure 2 This embodiment is applied to shoes, and provides a breathable sole, including a midsole 2 and an outsole 1 arranged from top to bottom, and the outsole 1 is fixed to the bottom surface of the midsole 2 by gluing. The bottom of the midsole 2 is provided with an air cavity 3 of a whale-shaped structure at the heel position, and the air cavity 3 is connected to two air permeable pipes 4 communicating with the outside, which are respectively arranged at the rear end and the outer side of the heel of the midsole.

[0019] The top of the air cavity 3 is connected to a first air groove 5, and the ends of the first air groove 5 are connected to two second air grooves 6, and the two second air grooves 6 are in a V-shaped structure facing the sole of the foot; the ends of the two second air grooves 6 are connected by a third air groove 7 of an L-shaped structure, and a plurality of cascaded fourth air grooves 8 are arranged on the side of the third air groove 7 close to the toe position. The fourth air groove 8 is a diamond or rectangular structure with missing corners, and specifically, the fourth air groove 8 includes two branch air grooves 80 in an eight-shaped structure; the outer ends of the branch air grooves 80 are connected by an L-shaped connecting air groove 81.

[0020] The top corners of the plurality of fourth air grooves 8 are located on the longitudinal center line of the midsole, that is, the bending point of the connecting air groove 81 of each fourth air groove 8 is located on the longitudinal center line of the midsole 2 .

[0021] The first fourth air groove 8 near the third air groove 7 has two ends of its branch air groove 80 connected to two ends of the third air groove 7. The two ends 80 of the branch air groove of the rear stage fourth air groove 8 are connected to the connecting air groove 81 of the front stage fourth air groove 8, and the fourth air groove 8 located at the sole position is provided with a plurality of evenly distributed air holes 9.
