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, stuffiness and bacteria breeding in the shoes. Most of the foot sweat in the shoes appears between the soles of the feet and the soles of the shoes. The sweat here is difficult to evaporate and will accumulate on the insoles and insoles of the shoes where the feet step. The existing soles generally have poor air permeability. Therefore, the utility model proposes a breathable sole with good air permeability. Utility Model Content

[0003] In view of this, an object of the present invention is to provide a breathable sole to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a breathable sole, applied to shoes, comprising a midsole and an outsole arranged from top to bottom, wherein an air cavity is arranged at the heel position at the bottom of the midsole, and the air cavity is connected to one or more breathing ducts, and the breathing ducts are connected to the outside, and a Y-shaped branch air groove is connected to the side of the air cavity close to the sole of the foot; the two ends of the branch air groove are connected to an annular air groove, and a plurality of cascaded arc air grooves are arranged on the side of the annular air groove close to the sole of the foot, and the two ends of the arc air groove close to the annular air groove are connected to the annular air groove, and the two ends of the arc air groove of the rear stage are connected to the arc air groove of the front stage, and the arc air groove located at the sole of the foot is provided with a plurality of evenly distributed breathing holes.

[0005] Furthermore, the annular air groove is circular or elliptical.

[0006] Furthermore, the arc-shaped air groove is an ellipse with a missing corner, and the missing corner angle is 100°-120°.

[0007] Furthermore, the long axis direction of the arc-shaped air groove is consistent with the short side direction of the midsole.

[0008] Furthermore, the plurality of cascaded arc-shaped air grooves are arranged from large to small in the direction toward the toes.

[0009] Furthermore, there are two breathing ducts, which are respectively arranged at the rear end and the outer side of the heel of the midsole.

[0010] Furthermore, the structure of the air cavity is in the shape of a whale.

[0011] Beneficial Effects

[0012] Compared with the prior art, the utility model has at least the following advantages: through the whale-shaped air cavity, Y-shaped branch air groove, annular air groove and cascade arc air groove, a breathing system of the sole is formed, which effectively helps the air circulation between the sole and the sole, dissipates heat, has excellent air permeability, and makes the foot comfortable. When walking, the sole is squeezed and bent, so that the air cavity and each air groove are deformed, which accelerates the circulation of air. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 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.

[0017] 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.

[0018] 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.

[0019] See also Figure 1-Figure 2, this embodiment is applied to shoes, and proposes 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. 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 with two breathing ducts 4, which are respectively arranged at the rear end and the outer side of the heel of the midsole 2, and the breathing ducts 4 are connected to the outside. The side of the air cavity 3 close to the sole position is connected with a Y-shaped branch air groove 5; the two outer ends of the branch air groove are connected with a circular or elliptical annular air groove 6, and the side of the annular air groove 6 close to the sole position is provided with a plurality of cascaded arc-shaped air grooves 7, and the two ends of the arc-shaped air groove 7 close to the annular air groove 6 are connected with the annular air groove 6, and the two ends of the arc-shaped air groove 7 of the rear stage are connected with the arc-shaped air groove 7 of the front stage, and the arc-shaped air groove 7 located at the sole position is provided with a plurality of evenly distributed breathing holes 8, and the breathing holes 8 are connected to the top surface of the midsole 2.

[0020] In the technical solution of the utility model, the arc-shaped air groove 7 is an ellipse with missing corners. The long axis direction of the arc-shaped air groove is consistent with the short side direction of the midsole. The missing angle α of the missing corner ellipse is 100°-120°. The multiple cascaded arc-shaped air grooves 7 are arranged from large to small in the direction toward the toes, presenting a series of bubble-like structures, and in combination with the annular air groove 6, the branch air groove 5 and the whale-shaped air cavity 3, the respiratory system of the entire midsole is shaped like a whale's air jet, which is interesting.

[0021] When in use, the whale-shaped air cavity 3, the Y-shaped branch air groove 5, the annular air groove 6 and the cascaded arc-shaped air grooves form a breathing system of the sole. Compared with the existing sole structure, it effectively helps the air flow between the sole and the sole, dissipates heat, has excellent air permeability, and makes the foot comfortable. When walking, the sole is squeezed and bent, so that the air cavity and the air grooves are deformed, which accelerates the circulation of air.
