Description

Technical Field

[0001] This utility model relates to the field of shoe insole technology, and in particular to a shock-absorbing memory foam shoe insole with matrix ventilation holes. Background Technology

[0002] Memory foam insoles, also known as slow rebound insoles, are a type of polyurethane polymer with an open-cell structure. This material has special viscoelastic properties, exhibiting very soft material characteristics and a strong impact energy absorption capacity. When subjected to external pressure, it can disperse pressure through the slow deformation of the molecular chains, avoiding local stress concentration. After the external force is released, the molecular chains can gradually return to their original shape, achieving the "slow rebound" effect.

[0003] Currently, when using shock-absorbing memory foam insoles, due to the dense structure of memory foam, its breathability is poor. To improve this, some products use a small number of irregular or simply arranged ventilation holes on the surface of the insole. However, this approach often has two disadvantages: too few or too small holes will have a negligible improvement effect, while blindly increasing or adding more holes will significantly weaken the support and shock absorption performance of memory foam, resulting in uneven support and easy collapse, making it difficult for the insole to have both breathability and shock absorption properties. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing memory foam insole with a matrix of breathable holes to solve the problem mentioned in the background art that it is not convenient to make the insole have both breathable and shock-absorbing properties.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a shock-absorbing memory foam insole with matrix ventilation holes, comprising an upper memory foam pad and a lower memory foam pad composite thereunder, wherein the upper memory foam pad is provided with matrix gradient units on the forefoot and heel, the matrix gradient units including small ventilation holes, medium ventilation holes and large ventilation holes, the lower memory foam pad is provided with a groove airflow channel network on the forefoot and heel, and the lower memory foam pad is provided with an embedding groove at the arch, wherein a stabilizing component is provided inside the embedding groove.

[0008] As a further embodiment of this utility model, the matrix gradient unit consists of nine holes in a 3x3 grid, with the small ventilation hole located at its center, four medium ventilation holes located at the edges of the small ventilation holes, and the large ventilation holes located at its four corners.

[0009] As a further embodiment of this utility model, the small, medium, and large air vents are all designed with a micro-conical shape, where the upper diameter is slightly larger than the lower diameter.

[0010] As a further embodiment of this utility model, vertical air holes are provided in the two grooved airflow channel networks, with the same position as the matrix gradient unit of the upper memory foam pad.

[0015] (III) Beneficial Effects

[0016] This invention provides a shock-absorbing memory foam insole with a matrix of breathable holes, which has the following beneficial effects:

[0017] 1. This shock-absorbing memory foam insole with matrix ventilation holes creates a three-dimensional air circulation system by setting matrix gradient units consisting of small, medium, and large ventilation holes in the forefoot and heel of the upper memory foam pad, which are connected to the corresponding groove airflow channel network on the lower memory foam pad. This system not only significantly enhances the breathability and heat dissipation performance of the insole and effectively removes moisture and heat, but also ensures the structural integrity of the memory foam material by the matrix and gradient distribution of the holes, maximizing the preservation of its original slow rebound and uniform pressure distribution characteristics. This cleverly solves the technical contradiction of traditional breathability design and shock absorption performance being difficult to balance.

[0018] 2. This shock-absorbing memory foam insole with matrix ventilation holes, through the setting of stabilizing components, forms a highly elastic and supportive hollow support bridge with the frame and "X" reinforcement during use. This helps to provide stable support for the arch area and prevent the insole from twisting and collapsing during exercise. In addition, the fiber mesh with silver ions on the surface provides antibacterial and deodorizing functions, and the cotton felt sweat-absorbing layer at the bottom further absorbs residual sweat. Working together with the ventilation system, it achieves multiple functions of shock absorption, support, breathability, antibacterial and sweat absorption, significantly improving the overall comfort and hygiene of wearing the shoes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a shock-absorbing memory foam insole with matrix ventilation holes, comprising an upper memory foam pad 1 and a lower memory foam pad 2 composite therebelow. The upper memory foam pad 1 has matrix gradient units on both the forefoot and heel, each unit including small ventilation holes 3, medium ventilation holes 4, and large ventilation holes 5. The lower memory foam pad 2 has a grooved airflow channel network 6 on both the forefoot and heel. By setting the matrix gradient units composed of small ventilation holes 3, medium ventilation holes 4, and large ventilation holes 5 on the forefoot and heel of the upper memory foam pad 1, and connecting them with the corresponding grooved airflow channel network 6 on the lower memory foam pad 2, a three-dimensional air circulation system is created. This system not only significantly enhances the breathability and heat dissipation performance of the insole, effectively expelling moisture and heat, but the matrix and gradient distribution of the holes also ensures the structural integrity of the memory foam material. The design maintains the original slow rebound and even pressure distribution characteristics to the maximum extent, thus cleverly solving the technical contradiction of traditional breathability and shock absorption performance. The lower memory foam pad 2 has an embedded groove 7 at the arch, and a stabilizing component 8 is set inside the embedded groove 7. Through the setting of the stabilizing component 8, the frame 801 and the "X" reinforcement 802 form a highly elastic and highly supportive hollow support bridge during use, which helps to provide stable support for the arch position and prevent the insole from twisting and collapsing during exercise. In addition, the fiber mesh 9 with silver ions on the surface provides antibacterial and deodorizing functions, and the cotton felt sweat-absorbing layer 10 at the bottom further absorbs residual sweat. Working together with the breathability system, they achieve multiple functions of shock absorption, support, breathability, antibacterial and sweat absorption, significantly improving the overall comfort and hygiene of wearing.

[0026] The matrix gradient unit consists of nine holes arranged in a 3x3 grid. Small vent holes 3 are located at the center, four medium vent holes 4 are located at the edges of the small vent holes 3, and large vent holes 5 are located at the four corners. By setting up the matrix gradient unit, the vent diameter is differentiated according to the pressure distribution characteristics within a unit area, thereby maximizing the air permeability and optimizing the structural strength.

[0027] The small vent 3, medium vent 4, and large vent 5 all adopt a micro-conical design with the upper diameter slightly larger than the lower diameter. The micro-conical design facilitates the unidirectional flow of air from top to bottom under foot pressure, while preventing backflow of moisture and foreign matter from the lower layer, thus improving the efficiency of active ventilation.

[0028] The two grooved airflow channel networks 6 have vertical air holes in the same position as the matrix gradient unit of the upper memory foam pad 1. The grooved airflow channel network 6 is vertically connected to the matrix gradient unit, which guides and diffuses the air entering from the upper vent to the bottom and sides of the insole, forming a three-dimensional airflow channel that runs through the thickness of the insole and forms an air circulation with the space inside the shoe, thereby effectively removing hot and humid air.

[0029] The stabilizing component 8 includes a frame 801 embedded in the mounting groove 7. The frame 801 has an integrated "X" reinforcement 802 stamped diagonally inside. The stabilizing component 8 provides dynamic and stable elastic support for the arch of the foot, effectively preventing the insole from collapsing or breaking due to bending during long-term use or strenuous exercise, and ensuring the durability of the arch support.

[0030] The frame 801 and the "X" reinforcement 802 are made of silicone. The frame 801 and the "X" reinforcement 802 form a hollow support bridge. Through the setting of silicone material and hollow support bridge structure, it can maintain the high elasticity and flexibility of the material while ensuring sufficient support rigidity, so as to make the support comfortable and not uncomfortable to the feet.

[0031] The surface of the memory foam pad 1 is composited with a fiber mesh 9. The surface of the fiber mesh 9 is coated with silver ions through ion exchange technology. The fiber mesh 9 with silver ions can inhibit the growth of bacteria in foot sweat, reduce odor from the source, and improve the hygiene and health protection of the insole.

[0032] The bottom of the memory foam pad 2 is laminated with a sweat-absorbing layer 10, which is made of cotton felt. The sweat-absorbing layer 10 absorbs and temporarily stores the small amount of sweat or moisture that seeps down from above, keeping the bottom of the insole and the insole dry, preventing sweat from accumulating and damaging the shoes, and serving as the last line of defense for the breathability system.

[0033] In this invention, the working steps of the device are as follows:

[0034] First step: When the foot steps on the insole, the upper memory foam pad 1 and the lower memory foam pad 2 exert their slow rebound characteristics, absorb the impact and distribute the pressure evenly, and the stabilizing component 8 at the arch provides elastic support to stabilize the gait;

[0035] The second step: foot pressure causes the hot and humid air inside the shoe to be forced into the insole through the micro-cone matrix gradient unit. After the air enters, it is diffused laterally and guided longitudinally through the groove airflow channel network 6 on the lower memory foam pad 2, and finally discharged from the edge and bottom of the insole to a larger space in the shoe cavity.

[0036] The third step: During the breathable circulation process, the fiber mesh 9 in contact with the foot continuously inhibits bacterial growth. A small amount of sweat that cannot evaporate in time is guided downwards, and some is absorbed and temporarily stored by the cotton felt absorbent layer 10, gradually evaporating in subsequent breathable circulations, thus working together to keep the foot contact surface and the inner environment of the shoe dry and clean.

However, those skilled in the art, understanding the principle of the above utility model, can clearly understand the specifics of its power mechanism, power supply system, and control system. The control method in the application document is automatic control through a controller, and the control circuit of the controller can be implemented by those skilled in the art through simple programming.

The machinery, parts and equipment adopt conventional models in the existing technology, and the structure and principle of the components known to those skilled in the art can be known by those skilled in the art through technical manuals or conventional experimental methods.
