Description

Technical Field

[0001] The utility model relates to the technical field of insoles, and more specifically, to a breathable insole. Background Art

[0002] Shoes are necessities in people's daily life, and insoles are cushioning components placed on the inner bottom of shoes. They can make loose shoes fit better, improve the contact between the bottom of the feet and the soles, make the inner bottom of the shoes flat and smooth for comfortable wearing, and at the same time, have the functions of keeping the inner bottom of the shoes perfectly clean, removing foot sweat and absorbing moisture.

[0003] At present, in order to have certain breathable and heat-dissipating performance, ventilation holes are provided on the part of the insole that contacts the human foot. However, in actual use, the middle layer of the insole will block the lower opening of the ventilation opening, and the human foot will block the upper opening of the ventilation opening, resulting in the ineffective dissipation of heat in the ventilation holes and thus failing to achieve a good ventilation effect. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a breathable insole to solve the above technical problems.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A breathable insole includes an insole main body. The insole main body includes an anti-odor and antibacterial layer, an elastic middle layer, a traditional Chinese medicine layer, and a breathable layer from bottom to top. The breathable layer is distributed with a number of heat dissipation cavities, and the top surface of each heat dissipation cavity is densely covered with a number of first ventilation holes. A convergence cavity is formed at the corresponding position of the breathable layer corresponding to the human foot arch. There is a ventilation channel between the convergence cavity and each heat dissipation cavity, and a number of second ventilation holes are arrayed on the top surface of the ventilation channel. A number of third ventilation holes are opened on the inner side wall of the insole main body at the corresponding position of the convergence cavity.

[0006] The utility model is further provided that: Two ventilation channels are provided between each heat dissipation cavity and the convergence cavity.

[0007] The utility model is further provided that: There are four heat dissipation cavities, and the four heat dissipation cavities are spaced apart on the outer side of the sole and facing the direction of the foot arch.

[0008] The utility model is further provided that: The anti-odor and antibacterial layer is composed of a bamboo fiber antibacterial layer and a mint fiber layer.

[0009] The utility model is further provided that: The traditional Chinese medicine layer includes an upper covering layer, traditional Chinese medicine materials, and a lower covering layer. Diffusion micropores are formed on the side of the upper covering layer close to the breathable layer.

[0010] The utility model is further provided that: The traditional Chinese medicine materials include a mixture of graphene and polyether.

[0011] The present utility model is further configured such that a number of protrusions are distributed at intervals on the upper surface of the elastic middle layer.

[0012] In summary, the present utility model has the following beneficial effects: A number of heat dissipation cavities are distributed on the insole body. When worn, the heat of the human foot enters the heat dissipation cavity through the first ventilation holes or enters the ventilation channel through the second ventilation holes, and the heat finally enters the confluence cavity. Since the confluence cavity is located at the corresponding position of the human foot arch, due to the arch of the foot arch, there is a relatively large space at the confluence cavity, which is conducive to the dissipation of the heat of the gas in the confluence cavity, thereby effectively improving the ventilation and heat dissipation effect of the sole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0019] Please refer to Figures 1-3As shown in the figure, an air-permeable insole according to an embodiment of the present utility model includes an insole main body 1. The insole main body 1 includes an odor-proof and antibacterial layer 10, an elastic middle layer 11, a traditional Chinese medicine layer 12, and an air-permeable layer 2 from bottom to top. The air-permeable layer 2 is distributed with a plurality of heat dissipation cavities 20. The top surfaces of the heat dissipation cavities 20 are densely covered with a plurality of first air holes 21. An intersection cavity 22 is formed at the corresponding position of the insole main body 1 corresponding to the human foot arch. There is an air-permeable channel 23 between the intersection cavity 22 and each heat dissipation cavity 20, and a plurality of second air holes 24 are arrayed on the top surface of the air-permeable channel 23. A plurality of third air holes 25 are opened on the inner side wall of the insole main body 1 corresponding to the intersection cavity 22.

[0020] During use, a plurality of heat dissipation cavities 20 are distributed on the insole main body 1. When worn, the heat of the human foot enters the heat dissipation cavities 20 through the first air holes 21 or enters the air-permeable channel 23 through the second air holes 24, and the heat finally enters the intersection cavity 22. Since the intersection cavity 22 is at the corresponding position of the human foot arch, due to the arch of the foot arch, there is a large space at the intersection cavity 22, which is conducive to the divergence of the gas heat in the intersection cavity 22, thereby effectively improving the air-permeable and heat-dissipating effect of the shoe sole.

[0021] Two air-permeable channels 23 are provided between each heat dissipation cavity 20 and the intersection cavity 22.

[0022] During use, the air-permeable channel 23 ensures the effective guidance of the air inside the heat dissipation cavity 20 to the intersection cavity 22. At the same time, the air-permeable channel 23 extends outward along the direction of the foot arch, and the air-permeable channel 23 covering the insole can further improve the air-permeable and heat-dissipating effect of the insole.

[0023] Four heat dissipation cavities 20 are distributed, and the four heat dissipation cavities 20 are spaced apart on the outer side of the sole and facing the direction of the foot arch.

[0024] During use, the four heat dissipation cavities 20 can fully ensure the air permeability and heat dissipation at each position when the human foot is worn.

[0025] The odor-proof and antibacterial layer 10 is composed of a bamboo fiber antibacterial layer 13 and a mint fiber layer 14.

[0026] During use, the odor-proof and antibacterial layer 10 can make the insole have better odor-proof and antibacterial capabilities.

[0027] The traditional Chinese medicine layer 12 includes an upper covering layer 15, traditional Chinese medicine materials 16, and a lower covering layer 17. Diffusion micropores 18 are formed on the side of the upper covering layer 15 close to the air-permeable layer 2.

[0028] During use, the diffusion micropores 18 are opened to facilitate the full volatilization of the traditional Chinese medicine materials 16. Further, when the gas in the heat dissipation cavities 20 and the air-permeable channels 23 circulates, it will also promote the volatilization of the traditional Chinese medicine materials 16 in the traditional Chinese medicine layer 12.

[0029] The traditional Chinese medicine materials 16 include a mixture of graphene and polyether.

[0030] When in use, graphene has the effects of improving blood circulation, relieving pain, and antibacterial and bacteriostatic. The 16 types of traditional Chinese medicine materials can be increased, decreased, or replaced according to actual production needs. For example, Carex meyeriana Kunth, lavender, or mugwort can be used.

[0031] Among them, Carex meyeriana Kunth has the effects of removing odors and sterilizing, and releasing the unique aromatic smell of Carex meyeriana Kunth, thereby improving the air permeability and antibacterial performance of the insole; lavender has the effect of eliminating sweat odor, and can emit fragrance when idle, which is beneficial to inhibiting odor and has a certain antibacterial and deodorizing effect; mugwort has the traditional Chinese medicine effects of regulating qi and blood, and dispelling dampness and cold.

[0032] A number of protrusions 19 are distributed at intervals on the upper surface of the elastic middle layer 11.

[0033] When in use, the elastic middle layer 11 is made of a highly elastic material to ensure the overall elasticity of the insole. The protrusions 19 are provided to have a massaging effect and improve blood circulation when the user wears and walks.

[0034] At the same time, it should be noted that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present invention.

[0035] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches should also be regarded as within the protection scope of the present invention.
