Abstract
Description
Technical Field
[0001] The utility model relates to the field of insoles, in particular to an anti-sweat type elastic cotton insole. Background Art
[0002] Insoles can provide comfortable foot support for the soles of the feet. In the shoemaking and health care industries, most of the structures of sports shoe insoles are composed of soft foam. The foam is soft and has microscopic gaps and has certain water absorption.
[0003] Although the insole foam is water-absorbent, the middle part of the insole is closely attached to the sole of the foot, so the sweat in the middle part of the insole is not easy to evaporate and will bring a stuffy and humid feeling to the sole of the foot, which is easy to cause bacteria to breed and cause odor. The circumference of the insole is not covered by the sole of the foot, so the sweat absorbed by the circumference of the insole is easy to evaporate. The purpose of the utility model is to propose a new insole structure to solve the problem that sweat is easily retained in the middle part of the insole, causing stuffy feet. Utility Model Content
[0004] The utility model aims to provide a sweat-proof insole with elastic cotton to solve the problems mentioned in the background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: it includes a foam main body, a first fabric layer, a second fabric layer and a waterproof side wall, the first fabric layer is located on the bottom surface of the foam main body and is connected to the foam main body in a circumferential direction, the water absorption of the first fabric layer is greater than the water absorption of the foam main body, the second fabric layer is located below the first fabric layer and is connected to the second fabric layer, the water absorption of the second fabric layer is greater than the water absorption of the first fabric layer, the waterproof side wall is connected to the second fabric layer and surrounds the side of the second fabric layer, and the space between the waterproof side wall and the first fabric layer, the second fabric layer and the foam main body constitutes a sweat storage tank.
[0006] In order to optimize the above technical solution, further measures are taken: the height of the waterproof side wall is flush with the height of the foam body. The purpose of this design is to ensure the sweat storage tank's sweat capacity while not affecting the wearing and use of the insole.
[0007] As a further improvement of the above technical solution: it also includes a waterproof bottom membrane, which covers the foam body, the first fabric layer and the bottom surface of the second fabric layer. The waterproof bottom membrane is connected to the waterproof side wall. By setting the waterproof bottom membrane, sweat can be concentrated and absorbed by the first fabric layer and the second fabric layer.
[0008] As a further improvement of the technical solution: the foam body does not completely cover the first fabric layer, and the exposed first fabric layer increases its contact area with sweat, which helps to improve the first fabric layer's ability to absorb sweat.
[0009] As an improvement to the above technical solution: the first fabric layer does not completely cover the second fabric layer, and the exposed second fabric layer increases its contact area with sweat, which helps to improve the second fabric layer's ability to absorb sweat.
[0010] 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:
[0011] The utility model provides an anti-sweat type insole elastic cotton, which achieves sweat separation through the difference in water absorption, and can transfer the sweat secreted by the sole of the foot to the second fabric layer and the sweat storage groove which are not covered by the sole of the foot, thereby helping to achieve the evaporation of sweat and reducing the discomfort caused by sweat to the bottom surface of the sole of the foot.

[0016] 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.
[0017] Example
[0018] See also Figure 1 and 2 The utility model provides a sweat-proof insole elastic cotton, comprising a foam body 1, a first fabric layer 2, a second fabric layer 3, a waterproof side wall 4 and a waterproof bottom membrane 5. The first fabric layer 2 is located on the bottom surface of the foam body 1 and is circumferentially connected to the foam body 1. The water absorption of the first fabric layer 2 is greater than that of the foam body 1, and the foam body 1 does not completely cover the first fabric layer 2.
[0019] The second fabric layer 3 is located below the first fabric layer 2 and connected to the second fabric layer 3. The water absorption of the second fabric layer 3 is greater than that of the first fabric layer 2. The first fabric layer 2 does not completely cover the second fabric layer 3. It should be noted that the first fabric layer 2 and the second fabric layer 3 refer to material layers composed of fabrics. The specific type of fabric used is not the content to be protected by the applicant. During implementation, technical personnel can choose different types of fabrics to participate in the production of insoles according to actual needs. As long as the aforementioned requirements on water absorption can be met, they can be applied without substantial impact on the technical effect.
[0020] The waterproof side wall 4 is connected to the second fabric layer 3 and surrounds the side of the second fabric layer 3. The height of the waterproof side wall 4 is flush with the height of the foam body 1. The space between the waterproof side wall 4 and the first fabric layer 2, the second fabric layer 3 and the foam body 1 forms a sweat storage tank 401.
[0021] The waterproof bottom membrane 5 covers the bottom surfaces of the foam body 1, the first fabric layer 2 and the second fabric layer 3. The waterproof bottom membrane 5 is connected to the waterproof side wall 4. The waterproof side wall 4 and the waterproof bottom membrane 5 refer to side wall-shaped and membrane-shaped components made of waterproof materials, preferably rubber materials.
[0022] Working principle: The foam body 1 is in contact with the sole of the foot and can absorb the sweat secreted by the sole of the foot. Since the water absorption of the foam body 1 is lower than that of the first fabric layer 2, the sweat absorbed by the foam body 1 will gradually transfer to the first fabric layer 2 based on the difference in water absorption. Since the water absorption of the first fabric layer 2 is lower than that of the second fabric layer 3, the sweat absorbed by the first fabric layer 2 will gradually transfer to the second water absorption layer based on the difference in water absorption, thereby ensuring that the sweat secreted by the sole of the foot can be transferred to the part of the insole that has no contact with the sole of the foot, avoiding the sweat being tightly covered by the sole of the foot, causing a stuffy and humid feeling on the sole of the wearer's foot.
[0023] The sweat storage groove 401 is located on the circumference of the insole and has no contact with the sole of the foot. During wearing, the insole will be squeezed by the sole of the foot, and the sweat not absorbed by the first fabric layer 2 and the second fabric will be stored in the sweat storage groove 401, reducing the flow of sweat. The sweat storage groove 401 is located at the edge of the insole, and the sweat stored in the sweat storage groove 401 is more conducive to sweat evaporation than the middle part of the insole covered by the sole of the foot.
[0024] 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.
