Description

Technical Field

[0001] The utility model relates to the technical field of insoles, in particular to a ventilated and breathable insole. Background Art

[0002] Insoles are a kind of anti-wear and cushioning device widely used in shoes. However, when wearing shoes, in addition to the anti-wear and cushioning effects, their comfort, shock absorption and breathability effects cannot be ignored.

[0003] With the improvement of living standards, people have higher and higher requirements for wearing comfort. Whether the feet are comfortable or not is one of the aspects that people pay attention to. Most of the existing insoles only have a cushioning effect. When people exercise or in the hot weather in spring, summer and autumn, a lot of heat will accumulate in the feet. If the air permeability of the shoes is not good, many shoes will often feel damp and uncomfortable when worn due to poor air permeability, especially for people who sweat a lot of feet. The damp and hot feet are prone to athlete's foot and foot odor. In order to improve the problem of stuffiness when wearing shoes, insoles are generally directly perforated, or grooves and holes are connected to form a channel design so that hot air can flow in the shoes to reduce the feeling of dampness and heat. However, since the hot air is still limited to the sole and cannot produce circulation convection with the outside air, the heat dissipation effect is quite limited.

[0004] In view of this, the designer has made in-depth considerations on the many deficiencies and inconveniences caused by the imperfections in the existing insole structure design, and has actively researched, improved and trial-produced to develop the present utility model. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a ventilated and breathable insole that can improve wearing comfort.

[0019] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] like Figure 1 As shown, the utility model discloses an insole, which includes a sweat-absorbing layer 1, a breathable layer 2 and an anti-slip layer 3, wherein the breathable layer 2 is fixedly arranged between the sweat-absorbing layer 1 and the anti-slip layer 3. The sweat-absorbing layer 1, the breathable layer 2 and the anti-slip layer 3 are all existing materials, wherein the sweat-absorbing layer 1 can be a canvas layer, which is skin-friendly and sweat-absorbent, has a soft texture, strong moisture absorption capacity, and is durable, wear-resistant, corrosion-resistant, anti-bending, and anti-stretching; the breathable layer 2 can be an EVC layer, which is light and has good elasticity, can absorb ground vibrations, reduce impacts on the feet, and protect the health of the feet; the anti-slip layer 3 can be a polyurethane layer, which can effectively increase the adhesion of the insole and reduce the risk of slipping.

[0022] like Figures 2 to 5 As shown, the front part of the breathable layer 2 is provided with a plurality of exhaust holes 21 at the position corresponding to the sole of the foot, the rear part of the breathable layer 2 is provided with an air chamber 22 at the position corresponding to the heel, an air bag 3 is installed in the air chamber 22, an exhaust channel 23 is formed between the air chamber 22 and the exhaust hole 21, a plurality of air inlet channels 24 connected to the air chamber 22 are arranged at intervals on the rear side wall of the breathable layer 2, each air inlet channel 24 is provided with an air inlet check valve 4 connected to the air bag 3, and the air bag 3 is provided with an air outlet check valve 5 at the connection between the exhaust channel 23 and the air chamber 22. The air bag can be made of PVC or rubber, which helps to improve the elasticity and restoring force of the air bag.

[0023] The exhaust principle of the insole of the utility model is: when the user's heel touches the ground, pressure will be applied to the airbag 3 of the insole, and the gas in the airbag 3 can only be discharged from the air outlet one-way valve 5 along the exhaust channel 23, and sprayed out from the multiple exhaust through holes 21 of the sole of the foot. In the process of lifting and falling of the foot, the heel does not apply pressure to the airbag 3, the airbag 3 is reset, and the air outside the insole will enter the airbag 3 from the multiple air intake one-way valves 4 in the air intake channel 24 to realize the air intake process. Such a cycle enables the shoes to achieve the effects of exhaust, ventilation, sterilization, cooling, etc., so that the user's feet can remain dry and comfortable, and the problem of athlete's foot and foot odor can be effectively alleviated.

[0024] In order to enhance the ventilation effect and facilitate processing, the air chamber 22 and the exhaust channel 23 of the breathable layer 2 of the utility model both pass through the bottom of the breathable layer 2, and the breathable layer 2 and the anti-slip layer 3 are glued together.

[0025] like Figure 1 As shown, the sweat-absorbing layer 1 is provided with a plurality of air outlet holes 11 corresponding to the air exhaust holes 21 of the air-permeable layer 2 .

[0026] In this embodiment, the breathable layer 2 is provided with four exhaust holes 21 corresponding to the four toe gaps of the sole of the foot. Four branch channels 25 are formed between the exhaust channel 23 and the four exhaust holes 21. When the airbag 3 is exhausted, the air can be exhausted from the toe gaps of the user.

[0027] like Figure 6 As shown, the air intake check valve 4 includes a valve body 41 and a ball valve 42. A valve cavity 43 is provided in the valve body 41. The ball valve 42 is arranged in the valve cavity 43. A valve inlet 44 connected to the air intake passage 24 of the air permeable layer 2 is provided at one end of the valve cavity 41. The diameter of the valve inlet 44 is smaller than the diameter of the ball valve 42. A plurality of valve outlets 45 connected to the valve cavity 43 and the airbag 3 are provided at the other end of the valve cavity 42. The valve outlet 45 of the air intake check valve 4 is multi-porous, blocking the ball valve 42 in the valve cavity 43 without blocking air. The valve inlet 44 is a single hole. When the gas in the airbag 3 flows back from the valve outlet 45 into the valve cavity 43, the ball valve 42 blocks the valve inlet 44, thereby playing the role of a one-way valve.

[0028] Still Figure 6 As shown, the structure of the air outlet check valve 5 is the same as that of the air inlet check valve 4, and comprises a valve body 51, a ball valve 52, a valve cavity 53, a valve air inlet 54 and a valve air outlet 55. The valve air inlet 54 of the air outlet check valve 5 is connected to the airbag 3, and the valve air outlet 55 is connected to the exhaust channel 23 of the breathable layer 2.

[0029] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
