DETAILED DESCRIPTION

[0027] The air-permeable shoe pad provided by the utility model will be described in detail below in combination with the drawings and specific embodiments. Meanwhile, it is explained here that in order to make the embodiment more detailed, the following embodiments are the best and preferred embodiments, and other alternative ways can also be adopted by the skilled in the art to implement some known technologies; and the drawings are only for more specific description of the embodiment, and are not intended to specifically limit the utility model.

[0028] As Figures 1-5 shown, the embodiment of the utility model provides an air-permeable shoe pad, which comprises a shoe pad body 1, the shoe pad body 1 comprises an air fiber pad 2, the surface of the air fiber pad 2 is fixed with a surface pad 4, the surface pad 4 is fixedly connected with the air fiber pad 2 in a hot melt adhesive manner, the air fiber pad 2 is formed by cutting after disordered stacking of a wire rod of TPU material, a plurality of irregular gaps are arranged between the stacked wire rods, and the gaps generated in this way can improve the air permeability of the air fiber pad 2.

[0029] The positioning assembly 5 is used to prevent deformation of the shoe pad body 1 when the shoe pad body 1 is inserted into a shoe, the air fiber pad 2 has good air permeability, can keep the feet dry, reduce stuffiness and odor, and improve the comfort of wearing, the surface pad 4 is fixed on the surface of the air fiber pad 2, on the one hand, the surface pad 4 can protect the air fiber pad 2 and avoid abrasion caused by direct contact with the feet, and can also prevent the phenomenon of slipping between the feet and the air fiber pad 2; on the other hand, the surface pad 4 can be made of softer and skin-friendly materials, further improving the comfort when the feet contact the shoe pad, the positioning assembly 5 solves the problem that the ordinary shoe pad is easily deformed during insertion into the shoe, makes the insertion of the shoe pad more smooth, and also ensures the accuracy of the initial position of the shoe pad in the shoe, reducing the discomfort caused by subsequent displacement of the shoe pad.

[0030] As Figure 2 and Figure 5As shown, in this embodiment, the surface of the air fiber pad 2 is provided with a plurality of protrusions 3 corresponding to the foot bottom acupoints (not shown in the figure). The protrusions 3 are produced by randomly stacked TPU material wires, so that the air fiber pad 2 has a concave-convex grainy feeling on the side facing the foot bottom. The face pad 4 is attached to the surface of the protrusions 3. The human foot bottom is distributed with numerous acupoints, which are closely related to the health of the body. The protrusions 3 corresponding to the foot bottom acupoints on the air fiber pad 2 can stimulate the foot bottom acupoints during walking or standing, promote blood circulation in the feet, relieve foot fatigue, and may have a positive impact on the health of the body in the long term. The face pad 4 is attached to the surface of the protrusions 3, which not only ensures the stimulating effect of the protrusions 3 on the acupoints, but also avoids the discomfort caused by direct contact of the protrusions 3 with the feet, and plays a buffering and transitional role. The air fiber pad 2 and the face pad 4 are connected by ultrasonic high-frequency sealing around the four sides.

[0031] As shown in Figure 3 , in this embodiment, the positioning assembly 5 includes a positioning band 6 fixed on the side surface of the air fiber pad 2. The face pad 4 is wrapped on the surface of the positioning band 6. The positioning band 6 is fixed on the side surface of the air fiber pad 2, which provides additional support and constraint for the insole body 1. When the insole is inserted into the shoe, the positioning band 6 can enhance the overall structural strength of the insole body 1, so that it is not easy to be twisted and deformed. The face pad 4 wrapped on the surface of the positioning band 6 not only makes the appearance of the insole more neat, but also protects the positioning band 6 from being damaged by direct friction with the inner wall of the shoe, prolonging the service life of the positioning band 6. The positioning band 6 and the side surface of the air fiber pad 2 are fixedly connected by hot melt adhesive.

[0032] As shown in Figure 3 , in this embodiment, the positioning band 6 has a cavity 7 inside. The cross-sectional shape of the cavity 7 is rhombic. The rhombic cavity 7 has unique mechanical properties. During the insertion of the insole into the shoe, when subjected to external pressure, the rhombic cavity 7 can better disperse the pressure. Compared with other shapes of cavities 7, it has stronger bending resistance. This further enhances the supporting effect of the positioning band 6 on the insole body 1, more effectively prevents the insole from bending and deforming during insertion, and ensures that the insole can be smoothly inserted into the shoe and maintain a good shape.

[0033] As shown in Figure 3 , in this embodiment, the cavity 7 is filled with air. Air has a certain elasticity and pressure. After the cavity 7 is filled with air, the anti-deformation ability of the positioning band 6 is significantly improved. When the insole is inserted into the shoe, even if subjected to a larger external force, the buffering effect of the air can reduce the degree of deformation of the positioning band 6, thereby better protecting the insole body 1 from deformation.

[0034] As shown in Figure 4As shown, in the embodiment, two auxiliary grooves 8 are formed on the side of the positioning band 6 facing the surface pad 4, and the two auxiliary grooves 8 are symmetrically arranged about the middle part of the air fiber pad 2, the setting of the auxiliary grooves 8 increases the flexibility and adjustability of the positioning band 6, when the insole is folded in half and inserted into the shoe, the auxiliary grooves 8 can make the positioning band 6 more easily bent, reduce the difficulty of folding in half, and also better adapt to the shape of the space inside the shoe, the two auxiliary grooves 8 are symmetrically arranged about the middle part of the long edge of the air fiber pad 2, which ensures the balance and stability of the insole during the folding and inserting process, so that the stress on both sides of the insole is more uniform, further improving the convenience and accuracy of insertion.

[0035] As shown, Figure 3 In the embodiment, the corner of the air fiber pad 2 is provided with an arc chamfer, which avoids scratching and damage to the inside of the shoe caused by sharp corners, and also reduces the frictional resistance between the insole body 1 and the shoe, making the insole insertion more smooth.

[0036] Working principle: when the insole is inserted into the shoe, it is folded in half from the middle of the short edge of the insole body 1 downward, due to the existence of the positioning band 6, the bending resistance of the insole body 1 is improved, which avoids deformation during insertion, the rhombus-shaped cavity 7 further enhances the bending resistance of the positioning band 6, and the air filled inside improves the anti-deformation ability of the positioning band 6, which provides double protection against bending of the insole body 1 during insertion, after the insole body 1 is inserted into the shoe, it does not need to be adjusted multiple times, the positioning band 6 drives the insole body 1 to spread in the shoe by its own elasticity, during use, the positioning band 6 plays a role in positioning the insole body 1, preventing its side from deforming during wear, and the protruding part 3 on the air fiber pad 2 can correspond to the foot acupoints, improving the comfort of use, and the whole breathable insole realizes its functions of ventilation, deformation prevention and comfortable support through this process.

[0037] The utility model covers any alternative, modification, equivalent method and scheme which is made on the essence and range of the utility model. In order to make the public have the thorough understanding of the utility model, the specific details are explained in the above preferred embodiment of the utility model, and the utility model can also be completely understood without the description of these details for the person skilled in the art.

[0038] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection range of the utility model.
