Description

Technical Field

[0001] The utility model relates to the technology of insoles, in particular to a breathable insole structure. Background Art

[0002] Shoes are one of the necessities of human life. With the development and progress of society, people not only require good-looking styles and wearing comfort for the shoes on their feet, but also pay attention to the breathable and sweat-removing functions of the shoes; in the structure of shoes, the sole or insole is the most important part, which not only plays a load-bearing role, but also protects the sole of the foot. Due to the existence and continuous change of the force between the sole of the foot and the sole or insole, when the insole is not breathable, during long-term use by people, in the areas near the toes and the arch of the foot of the foot, due to excessive sweating, the humidity in the above areas increases, which will cause active bacterial metabolism, resulting in odor and discomfort in wearing the foot; traditional insoles are generally cut into a thin sheet of appropriate thickness according to the size of the shoe shape and laid inside the shoe body. Such insoles not only have no elasticity and a single structure, but also have poor air permeability and ventilation performance. The sweat generated by the feet is difficult to effectively and timely discharge, often resulting in the reproduction of bacteria, thus generating odor, which greatly affects the wearing comfort.

[0003] Later, a shoe product with a breathable function appeared on the market. Most of them achieve the mutual circulation of air inside and outside the shoe cavity through a hollow or non-closed shoe upper, thereby realizing the breathable function of the shoe product; however, the structure design of the shoe product is not good. It can only increase the air permeability of the instep position, and the air at the sole position still cannot be well dredged and exhausted. After long-term wearing, it is very uncomfortable, affecting the wearing comfort of users and having a small scope of application.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the utility model is to provide a breathable insole structure, which uses air flow to flow into the breathable channel from the air vent or the air inlet and outlet channel, and then flows out from the air inlet and outlet channel or the air vent, so as to realize the formation of an air flow cycle inside the insole body, improve the breathable effect of the shoe product, improve the user experience effect, and have a wide range of applications.

The second airbag cavity at the frontmost end communicates with the last segment of the first airbag cavity on the left side of the forefoot area. One end of the air inlet / outlet channel communicates with the last second airbag cavity.

[0009] As a preferred solution, the first airbag cavity, the second airbag cavity and the first breathable channel are in a Y shape.

[0010] As a preferred solution, a third airbag cavity is further arranged on the hindfoot area. There are a number of third airbag cavities and they are arranged at intervals in a ring shape. The third airbag cavities are located at the rear end of the second airbag cavities. All of the number of third airbag cavities are interconnected through a second breathable channel. The third airbag cavities and the second airbag cavities are connected through a connecting channel.

[0011] As a preferred solution, a fourth airbag cavity is arranged between the number of third airbag cavities. The volume of the fourth airbag cavity is larger than that of the third airbag cavity, the second airbag cavity and the first airbag cavity.

[0012] As a preferred solution, a fifth airbag cavity is further included. The fifth airbag cavity is arranged at intervals around the edges of the first airbag cavity in the forefoot area and the second airbag cavity in the hindfoot area on the forefoot area and the hindfoot area.

[0013] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it mainly realizes that airflow flows into the air permeable channel from the air permeable port or the air inlet and outlet channel through the design of each component, and then flows out from the air inlet and outlet channel or the air permeable port, so as to form air circulation in the insole body and improve the ventilation effect of the shoe product.
