Description

Technical Field

[0001] The utility model belongs to the field of insoles, and in particular relates to a popcorn foam insole. Background Art

[0002] In the prior art, insoles are usually made of Hypoli material, PU foam material, popcorn material (EUV material), etc., among which PU foam material has the advantages of air permeability and high cost performance, but it is easy to hydrolyze in a humid or high temperature environment, causing the material to become hard and brittle, crack or crush, so that the PU insole will hydrolyze when the foot is exposed to moisture or high temperature for a long time, affecting the normal use of the insole. The popcorn insole adopts a porous structure design, which has good moisture absorption, can absorb sweat from the foot in time, keep the foot dry and refreshed, and has good flexibility and elasticity, can support the foot well and reduce foot fatigue, but the cost of popcorn material is relatively high, which will increase the cost of the insole, which is not conducive to its promotion and use.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solutions of the utility model embodiments, the drawings required for describing the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, drawings can also be obtained based on these drawings without paying creative work.

[0016] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, 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] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 utility model.

[0018] See also Figure 1 As shown, the utility model is a popcorn foam insole, comprising a foam insole body 1, the inner circle of the bottom surface of the foam insole body 1 is provided with a groove 2, a film airbag 3 is fixedly installed inside the groove 2, and the film airbag 3 is filled with popcorn particles 4;

[0019] Among them, the foam insole body 1 is made of foamed PU material, and popcorn particles 4 are installed on the bottom of the foam insole body 1 through a film airbag 3, so that the insole has the high elasticity of popcorn material, can well support the foot and reduce foot fatigue, while retaining the air permeability of the PU foam material, so that the insole has high air permeability, and compared with pure popcorn insoles, the amount of popcorn material used is smaller, so that the cost of the insole is lower, which is conducive to the promotion and use of insoles.

[0020] Specifically, a plurality of film airbags 3 are provided, and the plurality of film airbags 3 are distributed in sections in the groove 2, and each film airbag 3 is filled with popcorn grains 4. When the foot walks, different parts of the sole are subjected to different forces. By arranging the film airbags 3 in sections along the bottom of the foam insole main body 1, popcorn grains 4 of different thicknesses can be filled in the corresponding film airbags 3 according to the force conditions of the insole, which is beneficial to the reasonable distribution of the popcorn grains 4. While ensuring the supporting elasticity of the insole, the use of popcorn grains 4 is reduced, thereby reducing the preparation cost of the insole. At the same time, the segmented design can reduce the volume of each film airbag 3, prevent the popcorn grains 4 in the film airbag 3 from moving and deviating under the pressure of the foot, thereby causing the popcorn grains in the film airbag 3 to be unevenly distributed.

[0021] Specifically, the bottom surface of the film airbag 3 is flush with the bottom surface of the outer circle of the foam insole body 1, so that the force is evenly applied to all parts of the insole when it is used.

[0022] Specifically, a through groove is provided in the groove 2 and passes through the foam insole main body 1, and a film airbag 3 is installed in the through groove. The film airbag 3 and popcorn particles 4 are installed by providing the through groove, so that when the insole is used, the main force-bearing area of ​​the top surface is directly in contact with the film airbag 3, so that the popcorn particles 4 in the film airbag 3 can directly absorb moisture and perspiration from the foot, keeping the foot dry and refreshed, and at the same time preventing the foam insole main body 1 from being hydrolyzed and damaged in a humid environment of the foot, thereby increasing the service life of the insole.

[0023] Specifically, the film airbag 3 is fixedly connected to the foam insole main body 1 by sewing or inlaying and pressing. When the film airbag 3 is arranged on the bottom surface of the groove 2, the film airbag 3 can be fixedly connected to the foam insole main body 1 by inlaying and pressing. When the film airbag 3 needs to be installed in the through groove, the film airbag 3 needs to be connected to the foam insole main body 1 by sewing to improve the stability of the connection between the film airbag 3 and the foam insole main body 1.
