Abstract

A thermal insulation insole, which comprises an upper insole (1) and a lower insole (2), characterized in that: a heating layer (3) is arranged between the upper insole (1) and the lower insole (2), and the heating layer ( 3) There is an airgel insulation layer (4) on the outer tight sleeve, and a thermal pad (5) is installed between the heating layer (3) and the upper insole (1), and the heating layer (3) is connected by a heat pipe (6) onto the thermal pad (5). The utility model generates heat through the heat-generating agent in the heat-generating layer under the action of foot pressure and air, and due to the thermal insulation effect of the airgel heat-insulating layer, most of the heat energy generated by the heat-generating layer is transferred to the heat-conducting pad through the heat-conducting tube, improving It is not affected by the external humid environment, and it can also play the function of heat preservation in extremely cold conditions.

Description

Insoles

technical field

The utility model belongs to the field of daily necessities, and in particular relates to an insole capable of heat preservation.

Background technique

With the rapid development of the economy, people pay more and more attention to their own health, especially the foot health, which they did not pay much attention to before. Various foot massage shops have sprung up like mushrooms after rain. Where the acupoints are located, massaging the soles of the feet is of great significance and good curative effect on human health. In winter, especially in the cold weather, people need to keep warm to prevent the severe cold. In the past, people burned coal to keep warm. Nowadays, people use air-conditioning, heating, and electric heating methods for heating. However, when people go to outdoor activities or work and study for a long time in places without heating facilities, such as standing guard, sentry, fishing, driving, reconnaissance, and forestry operations, they will Unable to keep warm is prone to frostbite, especially the human feet, because people walk upright, the weight of the whole body is pressed on the human feet, which makes the human feet heavy, and because there are many sweat glands on the feet, the feet are easy to be wet In winter, when the cold wind blows, the feet will feel very wet and cold, which makes people uncomfortable.

The insole is usually used by people to put it in the shoes, which can make the shoes more comfortable to wear and can keep people's feet warm. However, traditional insoles are generally made of cloth and lack the function of heat preservation. Can't play the effect of keeping warm to human body foot in cold winter.

The authorized patent number CN201790086U of the Chinese patent "Electric Heat Insulation Insole" discloses an electric heat insulation insole heated by a resistance wire and a heat conduction bag for heat conduction and heat preservation. It includes a heat-conducting bag filled with heat-conducting liquid. The main points of its structure are that the heat-conducting bag is arranged between the upper insole and the lower insole, and a resistance wire and a battery are arranged inside the lower insole, and a switch is arranged on the lower insole; the resistance wire, resistance, The switch is connected in series; the thermal conduction bag and the upper layer insole are provided with a through hole corresponding to the switch of the lower layer insole. But the resistance wire and the battery in this thermal insulation insole are easily affected with damp and lost the function of generating heat energy.

At present, with the rapid development of science and technology in the market, there is a thermal insulation material called aerogel, which is a solid material form, and the solid with the smallest density in the world. Since more than 99.8% of airgel is air, it is very Good heat insulation effect, one inch thick airgel is equivalent to the heat insulation function of 20 to 30 pieces of ordinary glass.

Utility model content

The purpose of this utility model is to provide a heat-insulating insole, which utilizes the excellent heat-insulating performance of the existing airgel material, avoids the drawbacks of the existing heat-insulating insoles that cannot function for a long time, and can be used without any external energy. Provides a continuous undertone for thermal insulation.

Technical solutions

In order to achieve the above technical purpose, the utility model designs a thermal insole, which includes an upper insole and a lower insole, and is characterized in that: there is a heating layer between the upper insole and the lower insole, and the heating layer is tightly covered with air condensation A heat-conducting pad is installed between the heat-generating layer and the upper shoe-pad, and the heat-generating layer is connected to the heat-conducting pad through a heat-conducting pipe.

The heating layer contains a heating agent.

The upper insole and the lower insole are tightly stitched.

The heat-generating layer is sewn together with the lower layer insole.

The heat conduction pad is sewn together with the upper shoe-pad.

Beneficial effect

The utility model generates heat through the heat-generating agent in the heat-generating layer under the action of foot pressure and air, and due to the thermal insulation effect of the airgel heat-insulating layer, most of the heat energy generated by the heat-generating layer is transferred to the heat-conducting pad through the heat-conducting tube, improving It is not affected by the external humid environment, and it can also play the function of heat preservation in extremely cold conditions.
