Description

Technical Field

[0001] The utility model relates to the field of sponge products, in particular to a low-hardness shock-absorbing sponge insole. Background Art

[0002] Insoles are essential daily necessities for people. They are generally used in conjunction with the soles of shoes and are placed on the surface of the soles. There are many types of insoles nowadays, such as massage insoles, shock-absorbing insoles, foam insoles, etc. Among them, most shock-absorbing insoles are air cushion shock-absorbing insoles and insoles made according to the elasticity of the material itself.

[0003] After searching, we found a low-hardness shock-absorbing sponge insole with the authorization announcement number CN220369574U. Although this insole has the advantages of large compression of the buffer body, better feedback rebound force and shock-absorbing effect, the insole has poor air permeability and the sponge has poor deodorizing effect on sweat, which makes the sponge insole prone to odor when worn for a long time.

[0004] Therefore, a low-hardness shock-absorbing sponge insole is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the present invention is to provide a low-hardness shock-absorbing sponge insole in order to solve the above-mentioned problems, thereby improving the poor air permeability of the insole and the poor deodorizing effect of the sponge on sweat, which causes the sponge insole to easily produce odor when worn for a long time.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme, a low-hardness shock-absorbing sponge insole, comprising: an upper sponge pad; a supporting mechanism, wherein the supporting mechanism is arranged at the bottom of the upper sponge pad and can make the upper sponge pad breathable and moisture-absorbent; wherein, the supporting mechanism includes a lower sponge pad arranged at the bottom of the upper sponge pad, a buffer pad is arranged on the top of the lower sponge pad, a middle layer bracket is arranged between the upper sponge pad and the lower sponge pad, and a breathable component is installed inside the middle layer bracket.

[0007] The breathable component includes an arched portion fixedly installed in the inner cavity of the middle layer support, and a plurality of ventilation holes are installed through the surface of the arched portion. The top and bottom of the inner cavity of the ventilation hole are fixedly installed with an activated carbon layer, and the inner cavity of the ventilation hole is installed with a filling piece, and the interior of the filling piece is filled with moisture-absorbing particles. A bamboo charcoal fiber pad is installed between the lower sponge pad and the middle layer support, and a plurality of ventilation holes are opened on the surface of the bamboo charcoal fiber pad. The top of the buffer pad passes through the ventilation holes and extends to the top of the bamboo charcoal fiber pad.

[0008] Preferably, mounting grooves are provided on both sides of the top of the lower sponge pad, an air cushion is installed inside the mounting groove, and the interior of the air cushion is filled with latex particles.

[0009] Preferably, mounting openings are provided on both sides of the surface of the bamboo charcoal fiber mat, and the top of the air cushion passes through the mounting openings and extends to the top of the bamboo charcoal fiber mat.

[0010] Preferably, the air cushion is made of a polyurethane component, and the latex particles are made of a latex component.

[0011] Preferably, micropores are provided on the surface of the vent hole, and the number of the micropores is multiple, and the micropores are equidistantly provided on the surface of the vent hole.

[0012] The beneficial effects of the utility model are:

[0013] By installing ventilation holes through the surface of the arched portion, the air permeability of the insole can be increased. At the same time, the filling piece cooperates with the moisture-absorbing particles filled inside during the ventilation process to absorb moisture in the gas during the ventilation process. While the ventilation holes are ventilating, the deodorizing property of the bamboo charcoal fiber pad is used to eliminate odors inside the shoes. This improves the air permeability of the insole while absorbing moisture inside the shoes, preventing excessive moisture inside the shoes from generating odors and affecting the comfort of the user.

[0014] By setting a middle layer support and an arched part between the upper sponge pad and the lower sponge pad, the insole can have a certain supporting performance without sacrificing the pedaling comfort. The air cushion is installed between the upper sponge pad and the lower sponge pad, which can increase the compression amount when stepping on, thereby improving the feedback and rebound force of the insole. At the same time, the latex particles filled inside the air cushion can prevent the lower sponge pad from deforming and affecting the comfort of the insole. BRIEF DESCRIPTION OF THE DRAWINGS
