Description

Technical Field

[0001] This utility model relates to the field of insole structure technology, specifically to a multi-layer massage insole. Background Technology

[0002] People's feet are prone to fatigue and stuffiness during prolonged walking. To alleviate foot fatigue and avoid stuffiness, functional insoles such as massage insoles and cooling insoles have appeared on the market. However, most existing massage insoles have fixed protrusions, limiting their massage effect; existing cooling insoles rely on fabric and lack active air circulation, making the cooling effect difficult to maintain. Some insoles have adopted multi-layered functional designs to achieve massage and cooling functions, but the interlayer coordination is poor, failing to fully utilize the changes in foot pressure during walking to achieve a combination of efficient massage and comfortable experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-layered massage insole that combines efficient massage and cooling sensation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-layer massage insole, comprising a top layer, a middle layer and a bottom layer arranged sequentially from top to bottom. The top layer is made of a cooling fabric. The middle layer includes a central airbag assembly and side airbags. The central airbag assembly is a closed structure and includes at least two interconnected airbags, which are positioned at acupoints on the foot. The side airbags are arranged along the circumference of the insole and communicate with the outside.

[0005] The surface layer is provided with micropores.

[0006] The diameter of the micropores is 0.5~1mm.

[0007] The density of the micropores is higher in the forefoot than in the heel.

[0008] The thickness of the surface layer is 1~2mm.

[0009] The intermediate layer also includes a crescent-shaped airbag, which is a sealed structure and is located at the arch of the foot.

[0010] The side airbag is equipped with a first one-way air valve and a second one-way air valve with opposite air outlet directions.

[0011] The bottom surface of the bottom layer is provided with anti-slip texture.

[0012] The thickness of the bottom layer is 2-3 mm.

[0013] The bottom layer is made of EVA (ethylene-vinyl acetate copolymer).

[0014] The beneficial effects of this utility model are as follows: The massage insole of this utility model is equipped with a central airbag component and side airbags, which can achieve dynamic massage and active air circulation cooling by walking and squeezing, and further avoid stuffiness by combining with the cooling fabric on the surface, thus improving the comfort experience of the feet.

[0016] 3. Bottom layer. Detailed Implementation

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figure 1 as well as Figure 2 A multi-layered massage insole includes a top layer 1, a middle layer 2, and a bottom layer 3 arranged sequentially from top to bottom. The top layer 1 is made of a cooling fabric. The middle layer 2 includes a central airbag assembly 21 and side airbags 22. The central airbag assembly 21 is a closed structure and includes at least two interconnected airbag bodies 211, which are located at acupoints on the foot. The side airbags 22 are arranged around the circumference of the insole and communicate with the outside.

[0019] As described above, the beneficial effects of this invention are as follows: The surface layer 1 of the massage insole is made of a cooling fabric, which can reduce foot stuffiness. The airbags 211 of the central airbag assembly 21 continuously massage the acupoints on the soles of the feet during walking, relieving foot fatigue; the interconnected airbags 211 can better coordinate with changes in the feet during walking to provide a massage, enhancing the soothing effect. The side airbags 22 can be compressed during walking, causing gas exchange between the airbags and the air inside the shoe. The air exchanges heat with the feet during the flow, enhancing the cooling experience by utilizing air flow and the cooling properties of the fabric.

[0020] Furthermore, the surface layer 1 is provided with micropores 11.

[0021] As can be seen from the above description, the micropores 11 are used to promote air circulation and keep the feet dry.

[0022] Furthermore, the diameter of the micropore 11 is 0.5~1mm.

[0023] Furthermore, the density of micropores 11 is higher in the forefoot than in the heel.

[0024] As can be seen from the above description, the forefoot area is prone to sweating, and the distribution density of micropores 11 is relatively high.

[0025] Furthermore, the thickness of surface layer 1 is 1~2mm.

[0026] As can be seen from the above description, the surface layer 1 is thinner, which improves the skin-friendly feel.

[0027] Furthermore, the intermediate layer 2 is made of TPU (thermoplastic polyurethane elastomer).

[0028] Furthermore, the thickness of TPU is 1~2mm.

[0029] As can be seen from the above description, the middle layer 2, as the core layer of the massage function, needs to have good elasticity and resilience.

[0030] Furthermore, the airbag bodies 211 are connected to each other through microchannels 212.

[0031] Furthermore, the intermediate layer 2 also includes a crescent-shaped airbag 23, which is a closed structure and is located at the arch of the foot.

[0032] As can be seen from the above description, a crescent-shaped air bladder is provided at the arch of the foot, which can better conform to the shape of the arch, provide good support, and distribute the pressure on the arch.

[0033] Furthermore, the side airbag 22 is provided with a first one-way air valve 221 and a second one-way air valve 222 with opposite air outlet directions.

[0034] As described above, the first one-way air valve 221 and the second one-way air valve 222 allow air to enter the side airbag 22 and exit the side airbag 22, respectively. Compared with a two-way air valve, the use of two one-way air valves improves ventilation efficiency and prevents the accumulation of moisture and heat inside the shoe; it also enhances wearing comfort and extends the lifespan of the insole.

[0035] Furthermore, the lower surface of the bottom layer 3 is provided with anti-slip texture.

[0036] The anti-slip texture can be any existing texture with anti-slip effect, such as raised, diamond, or herringbone patterns.

[0037] As can be seen from the above description, the lower surface of the bottom layer 3 is provided with anti-slip texture, which can increase the friction between the insole and the sole and prevent the insole from sliding inside the shoe.

[0038] Furthermore, the thickness of the bottom layer 3 is 2~3mm.

[0039] Furthermore, the material of the bottom layer 3 is EVA.

[0040] As can be seen from the above description, the bottom layer 3 is made of EVA, which has good support and shock absorption properties.
