Description

Leg warming surrounding tube

Technical Field

The invention relates to a leg warming surrounding tube, in particular to a leg warming surrounding tube which does not consume electric energy, can freely walk after being worn and can keep the lower legs warm.

Background

The shank is the necessary place for blood to pass between the thigh and the foot, the blood vessel of the shank is contracted in winter, the blood flow is not smooth, and the foot is always cold; in winter, the blood flow of the lower leg is smooth, the foot connected with the lower leg can be perfused with blood at any time, and the foot feels warm and flexible naturally.

In winter, the heat preservation of the lower leg is very important. The shank is kept warm, thereby not only protecting the shank, but also protecting the feet, and achieving two purposes at one stroke.

At present, the electric leg warmer is used for people to sit on a stool and surround the legs with the electric leg warmer, the temperature is adjustable, the use is convenient, and people feel warm and comfortable. Unfortunately, it has limitations.

Children cannot take a personal electric leg warming device to a classroom, even if the children take the device, where in the classroom is so many electric sockets, the wires on the floor are criss-cross, how do the people walk in the classroom? How is the teacher convenient to walk near the student for tutoring?

The elderly cannot always sit and they need to walk out frequently. In winter, the electric leg warmer cannot be taken out, and no electricity is available outdoors, so that the electric leg warmer has no effect. The outside cold can force people, the legs are not noticed to keep warm, and the feet are numb and hard, so that the people easily fall down.

There is a need in the society for a calf warming device that does not require electricity for portability and walking.

The social needs are the source of our creations.

Disclosure of Invention

The invention aims to provide a leg warming leg surrounding tube which does not consume electric energy, can freely walk after being worn and can keep the legs warm.

In order to solve the technical problem, the technical scheme of the invention is as follows:

a leg warming surrounding tube comprises a warming part and a connecting part.

The thermal insulation piece is trapezoidal after being unfolded, wide at the upper part and narrow at the lower part, cylindrical after being surrounded on the shank, thick at the upper part and thin at the lower part, and sequentially formed by laminating a surface layer, an air bubble layer, a reflecting layer and an inner layer from outside to inside.

The surface layer is cotton cloth, chemical fiber cloth or leather.

The air bubble layer has a substrate made of soft, nontoxic and low-thermal conductivity plastic sheet, multiple closed air bubbles densely distributed in the air bubble layer, and the outer surface of the air bubble layer is adhered to the inner surface of the surface layer.

The reflecting layer is a mirror copper film and is plated on the inner surface of the bubble layer substrate.

The inner layer is made of cotton cloth, camel hair or fur, and the outer surface of the inner layer is adhered to the inner surface of the reflecting layer.

The connecting piece is fixedly connected to the warm-keeping piece, so that the warm-keeping piece can be enclosed on the shank without being scattered, and the warm-keeping piece can be separated from the shank.

When the warm keeping piece is enclosed on the lower leg, the upper end of the warm keeping piece is close to the knee, the lower end of the warm keeping piece encloses the ankle, air in a plurality of closed bubbles on a bubble layer of the warm keeping piece prevents heat from being dissipated outwards through conduction and convection, and a mirror copper film on a reflecting layer reflects the heat radiation of the lower leg to the periphery back to the lower leg, so that the leg warming enclosure can not only keep the lower leg warm, but also does not consume electric energy, and people can move freely.

There are two preferred embodiments of the connector.

A first preferred version of the fastener is one which is known as a common hook and loop fastener.

A second preferred version of the connector is that known as a male and female snap.

After the structure is adopted, the matrix of the bubble layer of the thermal insulation part is a soft and nontoxic plastic sheet with low heat conductivity coefficient, so that the thermal insulation part is harmless to a human body, and the heat dissipated outwards through conduction is little.

After the structure is adopted, because a plurality of closed bubbles are densely distributed in the bubble layer of the thermal insulation piece, because the heat conductivity coefficient of the air in the bubbles is very small, the heat conducted outwards through the air in the bubbles is negligible, and the air between the bubbles does not have convection, thereby avoiding the heat from being outwards dissipated through the convection.

After the structure is adopted, the heat which occupies more than half of the total heat dissipated by the lower leg in an infrared radiation mode is left in the leg warming surrounding tube due to the reflection of the mirror copper film of the warm-keeping part reflecting layer to the infrared radiation.

After the structure is adopted, the heat-insulating piece carries out multiple blocking on three heat transfer modes, so that the lower leg can be effectively insulated. Blood in the blood vessels of the lower legs smoothly flows, so that the blood vessels in the feet can be perfused in time, and the feet cannot be numb and frostbitten.

After the structure is adopted, a new product which does not consume electric energy, can freely walk after being worn and has the function of keeping the lower legs warm is provided for the students in the primary school, the middle school and the primary school, even children in kindergarten and the old, and a gap is filled for the social requirement.
