The shoe adopts the breathable insole, so as to increase the air permeability and comfort to the sole.

Description

Technical Field

[0001] The utility model relates to the technical field of footwear, in particular to a breathable insole and a pair of shoes thereof. Background Art

[0002] At present, most of the breathable shoes on the market only rely on opening holes in the upper or using breathable fabrics to achieve the ventilation effect. The sweat glands on the soles of the feet are particularly dense, especially at the toes. During walking, the greater the body load, the more the sweat glands on the soles of the feet secrete. The high heat and high humidity environment in the shoes due to friction, squeezing, and sweating will not only make the feet uncomfortable to wear, but also cause active bacterial metabolism and produce odor. Therefore, the ventilation effect is not ideal. Better results can be achieved by combining sole ventilation. At present, the products on the market for sole ventilation include breathable insoles, but their structures are too simple and the effect is very poor, or their designs are too complicated, the production cost is high, and the effect is not necessarily ideal. Summary of the invention

[0003] The utility model aims to provide a breathable insole and shoes thereof to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A breathable insole comprises an insole layer, an air bag layer and a filler; the insole layer is a soft pad body, and the insole layer is attached to the air bag layer; a resilient filler is arranged inside the air bag layer corresponding to the rear sole, an air inlet is arranged above the air bag layer corresponding to the heel, an air outlet is arranged at the air bag layer corresponding to the forefoot, and the width of the air bag layer corresponding to the forefoot is smaller than the width of the forefoot; a protrusion is arranged between the insole layer and the air bag layer corresponding to the heel, so that an air inlet channel connected to the air inlet is formed therebetween, and the protrusion can be arranged on the insole layer or the filler.

[0006] As an improvement of the above solution, a side surround is provided at the edge of the insole layer. If the insole layer is made of a material with poor air permeability, air holes are provided in addition to covering the air inlet position; if the insole layer is made of a material with good air permeability, an airtight layer is provided to cover the air inlet position.

[0007] As an improvement to the above solution, the airbag layer and the filler can be integrated.

[0008] As an improvement of the above solution, the edges of the insole layer and the airbag layer corresponding to the air inlet position are provided with external protrusions, and the external protrusions can be provided on the insole layer or the airbag layer.

[0009] A pair of shoes using the breathable insole described in the above solution.

[0010] A shoe comprises a soft midsole, wherein the air bag layer described in the above scheme is embedded in the midsole.

[0011] In the above technical solution, the beneficial effects of the utility model are:

[0012] When a person wears the shoes with the breathable insole and walks or runs, and the heel touches the ground first, the insole layer and the air bag layer are pressed against each other at the corresponding heel position, so that the air inlet is closed and the air in the air bag layer is pressed to the moist and hot area of ​​the forefoot, thereby improving the air circulation at the contact part between the sole and the insole and reducing the accumulation of sweat, which is similar to the effect of keeping the back dry and comfortable by the ventilation function of a car seat. The air circulation in the shoe can also make it easier for the moist and hot air to be discharged out of the shoe through the existing breathable structure of the shoe.

[0013] When the forefoot touches the ground again and bends to exert force to lift the heel to make the person move forward, the upper and lower layers of the air bag layer corresponding to the forefoot position are squeezed and are in a close contact state. At this time, the air outlet is not connected to the air bag layer corresponding to the rear foot position. At the same time, because the heel is lifted, the bulge pushes up the insole layer, the air inlet returns to the open state, and the filling returns to its original state. The relatively dry and cold air near the shoe opening at the heel is affected by the negative pressure in the air bag layer, and will pass through the insole layer and be sucked into the air bag layer from the air inlet. Compared with the prior art, the utility model has the advantages of simple structure, low manufacturing cost, good ventilation effect, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. Example

[0022] Refer to the attached Figure 1-4 The breathable insole shown includes: an insole layer 1, an airbag layer 2, and a filler 3; the insole layer 1 is a soft pad body, and the insole layer 1 is attached to the airbag layer 2; a resilient filler 3 is provided inside the airbag layer 2 corresponding to the rear sole position, an air inlet 21 is provided above the airbag layer 2 corresponding to the heel position, and an air outlet 22 is provided at the airbag layer 2 corresponding to the forefoot position, and the width of the airbag layer 2 corresponding to the forefoot position is smaller than the width of the forefoot; a protrusion 31 is provided between the insole layer 1 and the airbag layer 2 corresponding to the heel position, so that an air inlet channel 4 connected to the air inlet 21 is formed therebetween, and the protrusion 31 can be provided on the insole layer 1 or the filler 3.

[0023] The specific implementation method is as follows: when a person is walking or running, in most cases the heel touches the ground first, and then the forefoot touches the ground and bends to exert force to lift the heel to move forward.

[0024] When a person wears the shoes with the breathable insole and walks or runs, the first action is that when the heel touches the ground first, the protrusion 31 is pressed into the air inlet 21, and at the same time, the insole layer 1 and the air bag layer 2 corresponding to the heel are in a close contact state after being pressed. Previously, because the protrusion 31 lifted the insole layer 1, the gap between the insole layer 1 and the air bag layer 2 corresponding to the heel position disappeared, and the air inlet channel 4 also disappeared. At this time, the air inlet 21 is in a closed state, and at the same time, the air bag layer 2 and the filler 3 are squeezed and compressed. The air in the air bag layer 2 is pressed to the forefoot and discharged from the air outlet 22 located at the forefoot. The discharged air will pass through the insole layer 1 and be discharged to the forefoot where the sweat glands are most dense, so that airflow is generated in the sole and the shoe.

[0025] In the second action, when the forefoot touches the ground again and bends to lift the heel to make the person move forward, the upper and lower layers of the air bag layer 2 corresponding to the forefoot position are squeezed and are in a close contact state. At this time, the air outlet 22 is not connected with the air bag layer 2 corresponding to the rear foot position. At the same time, because the heel is lifted, the protrusion 31 pushes up the insole layer 1, and a gap appears between the insole layer 1 and the air bag layer 2 corresponding to the heel position, so that the air intake channel 4 and the air intake port 21 are restored to a connected state, and the filler 3 returns to its original state. The relatively dry and cold air near the shoe opening at the heel is affected by the negative pressure in the air bag layer 2, and will pass through the insole layer 1 through the air intake channel 4, and be sucked into the air bag layer 2 from the air intake port 21.

[0026] It should be noted that when the upper and lower layers of the airbag layer 2 corresponding to the forefoot position are squeezed, in order to achieve a completely close fit and prevent the humid and stuffy air at the forefoot from entering the airbag layer 2 from the air outlet 22 and affecting the ventilation effect, the width of the airbag layer 2 corresponding to the forefoot position is smaller than the width of the forefoot.

[0027] It should also be noted that if the insole layer 1 is made of a material with poor air permeability, it is necessary to provide air holes 12 in addition to covering the air inlet 21, so that the air at the heel can smoothly pass through the insole layer 1 into the air bag layer 2, and the air in the air bag layer 2 can smoothly pass through the insole layer 1 to reach the forefoot; if the insole layer 1 is made of a material with good air permeability, an airtight layer 13 is provided covering the air inlet 21 to prevent the air bag layer 2 from being squeezed and the air inside it from being discharged from the air inlet 21 to affect the ventilation effect.

[0028] In the first embodiment, the edge of the insole layer 1 is provided with a side enclosure 11, which can concentrate the air in the airbag layer 2 and discharge it upward to the front sole of the foot, and can also play a stabilizing role to prevent the insole layer 1 and the airbag layer 2 from being misaligned.

[0029] In the first embodiment, the airbag layer 2 and the filler 3 can be integrated to further simplify the structure. For example, if a 3D printing process is used in the production process, the airbag layer 2 and the filler 3 can be formed in one step without placing the filler 3 separately.

[0030] In the first embodiment of the present invention, an outer protrusion 14 is provided on the edge of the insole layer 1 and the air bag layer 2 corresponding to the position of the air inlet 21. The outer protrusion 14 can be provided on the insole layer 1 or the air bag layer 2. The outer protrusion 14 can assist the protrusion 31 to quickly lift the insole layer 1 to prevent the insole layer 1 from being sucked at the air inlet 21 and affecting the air intake speed when the negative pressure in the air bag layer 2 is too large. Example

[0031] A pair of shoes using the breathable insole as described in the above solution. Example

[0032] A shoe comprises a soft midsole, in which the airbag layer 2 described in the above scheme is embedded. When the thickness of the midsole and the sole of the shoe remains unchanged and the overall weight of the shoe is not affected, for example, when it is used in lightweight running shoes, the original comfort and sports properties can still be maintained, and at the same time, better air permeability can be achieved.

[0033] Of course, the present invention is not limited to the above-mentioned embodiments, and the combination of different features of the above-mentioned embodiments can also achieve good results. Those skilled in the art can also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
