Description

Technical Field

[0001] The utility model relates to the field of insoles, in particular to an anti-odor foam insole. Background Art

[0002] Sports shoe insoles are generally made of foam as the main material. They are soft in texture and can support the sole of the foot to improve the adaptability of the sole and midsole. At the same time, the insole can act as a transition medium to improve wearing comfort.

[0003] The insole is covered by the sole of the foot, and sweat is easily absorbed by the insole. The sole of the foot, the shoe upper and the insole form a humid and hot space, and air is not easy to flow in this space. The sweat on the insole is easy to breed bacteria in a large number in a humid and hot environment and produce odor. The purpose of the utility model is to propose a new insole structure to solve the above technical problems and avoid the insole from producing odor and affecting the wearing experience. Utility Model Content

[0004] The utility model aims to provide an anti-odor foam insole to solve the problems mentioned in the background technology.

[0006] In order to optimize the above technical solution, further measures are taken: a forefoot pressure block is formed on the forefoot phalanx part of the top of the upper foam layer, and the forefoot pressure block is used to bear the force of the forefoot to ensure that the gap on both sides of the upper foam layer and the lower foam layer can be fully squeezed by the forefoot.

[0007] As a further improvement to the above technical solution: a heel pressing block is formed on the heel calcaneus portion of the top surface of the upper foam layer, and the heel pressing block is used to bear the force of the heel to ensure that the gap on both sides of the upper foam layer and the lower foam layer can be fully squeezed by the heel.

[0008] As a further improvement of the technical solution: it also includes a first fabric layer, which is located circumferentially and connected to the upper foam layer, and covers the through holes. Airflow in and out of the through holes can dry the first fabric layer covering the through holes.

[0009] As an improvement to the above technical solution: it also includes a second fabric layer, the second fabric layer and the first fabric layer can just cover the top surface of the upper foam layer, and the water absorption of the first fabric layer is greater than that of the second fabric layer.

[0010] As an improvement to the above technical solution: a convex strip is formed on the outer side of the foam side wall along the length direction of the foam side wall, and the outward convex strip can clamp the upper wall of the shoe to prevent the insole from moving.

[0011] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0012] The utility model provides an odor-proof foam insole, which utilizes the squeezing of the upper foam layer and the lower foam layer during wearing to generate airflow, so that the airflow can dry the first fabric layer through the through holes, and at the same time, the sweat on the second fabric layer can be transferred to the first fabric layer due to the difference in water absorption, which can promote the flow of air in the shoe cavity and the drying of sweat, and prevent the sweat from breeding bacteria in a hot and humid environment to produce odor and affect the wearing experience.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-2 The utility model provides an anti-odor foam insole, comprising an upper foam layer 1, a lower foam layer 2, a foam side wall 3, a first fabric layer 4 and a second fabric layer 5. The cross section of the upper foam layer 1 is in the shape of an inverted isosceles triangle, and a through hole 103 is formed circumferentially on the upper foam layer 1. A forefoot pressing block 101 is formed on the front metacarpal and phalangeal part of the top surface of the upper foam layer 1, and a heel pressing block 102 is formed on the heel calcaneal part of the top surface of the upper foam layer 1.

[0020] The lower foam layer 2 is located below the upper foam layer 1 and the middle portion of the lower foam layer 2 is connected to the middle portion of the upper foam layer 1 .

[0021] The foam side wall 3 surrounds the upper foam layer 1 and the lower foam layer 2, and the foam side wall 3 surrounds the gap formed by the sides of the upper foam layer 1 and the lower foam layer 2. Preferably, the foam side wall 3 uses the same material as the upper foam layer 1 and the lower foam layer 2, and a convex strip 301 is formed on the outer side of the foam side wall 3 along the length direction of the foam side wall 3.

[0022] The first fabric layer 4 is located on the upper foam layer 1 and connected to the upper foam layer 1 in the circumferential direction. The first fabric layer 4 covers the through holes 103 . The airflow in and out of the through holes 103 can dry the first fabric layer 4 covering the through holes 103 .

[0023] The second fabric layer 5 and the first fabric layer 4 can just cover the top surface of the upper foam 1 . The water absorption of the first fabric layer 4 is greater than that of the second fabric layer 5 . The transfer of sweat is achieved through the difference in water absorption between the first fabric layer 4 and the second fabric layer 5 .

[0024] The first fabric layer 4 and the second fabric layer 5 refer to material layers composed of fabrics. The specific type of fabric used is not the technical content to be protected by the applicant, nor is it a necessary technical feature of the technical solution. Technical personnel can choose different types of fabrics according to actual needs in the specific implementation. As long as the above-mentioned water absorption requirements are met, they can be applied and will not have a substantial impact on the technical solution.

[0025] Working principle: the upper foam 1 is in contact with the sole of the foot, and the sweat secreted by the sole of the foot can be absorbed by the first fabric layer 4 and the second fabric layer 5 through the contact. When the wearer walks, the sole of the foot will squeeze the upper foam 1 and the lower foam 2, so that the gap between the upper foam 1 and the lower foam 2 is intermittently squeezed, so that the air in the gap can leave from the through hole 103 in the form of airflow, which can promote air flow in the shoe cavity to prevent sweat from breeding bacteria and producing odor in a hot and humid environment. At the same time, in the process of airflow entering and exiting the through hole 103, the sweat absorbed by the first fabric layer 4 can be dried by the airflow, which cooperates with the breathable structure of the upper to help keep the shoe cavity and the first fabric layer 4 and the second fabric layer 5 dry.

[0026] Since the water absorption of the first fabric layer 4 is greater than that of the second fabric layer 5 , the sweat absorbed by the second fabric layer 5 can be transferred to the first fabric layer 4 after the first fabric layer 4 is dried by the air flow.

[0027] The force on the sole of the foot is mainly distributed along the line from the big toe bone of the forefoot to the calcaneus bone of the heel. The purpose of providing the forefoot pressure block 101 and the heel pressure block 102 is to support the sole of the foot so that the upper foam layer 1 and the lower foam layer 2 are fully squeezed.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
