Abstract

An electric heating shoe, which is the type of heat retainable, comprises a body of the shoe, and an electric heating member at the bottom of the body of the shoe. The electric heating member consists of a flexible and self-closable electric heater, and a circuit breaker for controlling temperature. The circuit breaker is at the rear of electric heater. The electric heating member is within a thermal insulating layer. A shoe-pad is placed on the thermal insulating layer. A socket is provided at the outer surface of the heel for the body of the shoe. There is also provided a power supply, which includes an indicator, a circuit breaker for timing, and two plugs. The electric heater would be heated rapidly as the power is supplied. The heating temperature could be controlled by both the circuit breaker for controlling temperature and the circuit breaker for timing. The heat is released through the thermal insulating layer. The heat preservation of the shoe is very well. The shoe is easily used and safe. The cost is lower.

Description

TECHNICAL FIELD

BACKGROUND OF THE INVENTION The present invention relates to a shoe with heating equipment, and particularly to a heat-storable electric shoe. BACKGROUND

In cold areas, people wear thermal shoes to protect their feet from the cold. The general thermal shoes are made of materials to increase the thickness of the shoe body to achieve thermal insulation. When the outdoor temperature is relatively low, Or in the winter when people are away for a long time, this traditional heat-insulated shoes seem to be powerless. Due to its poor heat insulation performance and short heat preservation time, the feet of people wearing this heat-insulated shoes in winter are often frostbite.

In order to overcome the shortcomings of the traditional thermal insulation shoes, an electric heating shoe has been introduced on the market. The structure is to provide an electric heating component at the bottom of the shoe. The power source used is generally a DC power source composed of multiple DC batteries. This type of electric heating shoes uses a series of multiple batteries as a direct current power source for heating components such as heating wires, which has low power, limited heat generation, short duration, and requires frequent replacement, is inconvenient to use, and the cost is too high, in addition, This electric heating shoe lacks effective thermal insulation measures, so the thermal insulation effect is poor and not ideal.

The purpose of the present invention is to provide a convenient, economical, safe, good thermal insulation effect, heat-storable heating shoes to overcome the shortcomings of current electric shoes. Technical solution

A heat-storable electric heating shoe includes a shoe body and an electric heating component, wherein the electric heating component is located at the bottom of the shoe body, and is characterized in that the electric heating component is composed of a flexible, self-enclosed electric heater and a temperature-controlled circuit breaker. The temperature-controlled circuit breaker is located at the rear of the self-closing electric heater. This electric heating component is located in a thermal insulation layer provided with a thickened insole on the thermal insulation layer. In addition, there is a socket on the outside of the heel of the shoe body, and an electric device. The power supply device includes an indicator light, a time-controlled circuit breaker, and two power plugs. Power plug connection-attached

The present invention will be described in detail with the help of the following drawings, in which Figure i is a schematic structural view of an embodiment of the present invention. Description of the best embodiment

The following describes in detail the heating and heat storage working principle of the heat-storable electric heating shoe according to the present invention with reference to the drawings.

As shown in FIG. 1, the heat-storable electric heating shoe 12 according to the present invention includes a shoe body 11 and an electric heating component 10, wherein the electric heating component 10 is located at the bottom of the shoe body 11, and the electric heating component 10 is a flexible, self-closing electric heater. 1 and the temperature-controlled circuit breaker 4. The temperature-controlled circuit breaker 4 is located at the rear of the self-closing electric heater 1, the electric heating component 10 is located in the thermal insulation layer 2 provided, and the thermal insulation layer ^{2 is} provided with a thick insole ³ .

When the weather is cold, when people need to wear the electric heating shoes and go out, the power plug 8 of the power supply device 13 is connected to the socket 5 of the sole of the shoe body 11, and the power plug 9 of the power supply device 13 is connected to an external power supply to heat the electricity. The heater 1 is quickly heated, and the heating temperature is controlled by a temperature-controlled disconnection ¾ 4 provided behind the electric heater 1 and a time circuit breaker 7 of the power supply unit 13. The indicator 6 is on during heating, and when the temperature is set, the indicator 6 is off. Because the electric heater 1 and the temperature-controlled circuit breaker ^{4 are} buried in the heat insulation layer ² , the heat released by the electric heater 1 is surrounded by the heat insulation layer ² , and part of the heat ^: exists in the heat insulation layer. When the electric heater 1 to the set temperature, the power will be automatically cut off after the heat preservation, the indicator light 6 goes out, and the power plugs 8 and 9 of the power supply unit 13 are unplugged. The user puts on the shoes, and the heat is slowly released from the heat insulation layer ² and the thickened insole. This can keep the shoe warm for a long time.

The above-mentioned flexible, self-closing electric heater 1 uses a resistance wire, which is heated to 180 for about ² minutes. After power failure, its temperature slowly releases heat through the mineral cotton filling, and the temperature of the insole is about 30 TC. Temperature-10 hours, the shoe's thermal insulation time can reach 1.5 ~ 2 hours, thus achieving a heat-storable electric heating shoe that can be heated quickly and warmed for a long time.

The specific heating temperature of the heat-storable electric heating shoe according to the present invention can be adjusted by the user according to the situation.

Due to the combination of commercially available temperature-controlled circuit breakers and time-controlled circuit breakers, self-sealing electric heaters are buried in mineral wool and thickened insoles ^{3 are} provided to ensure safe and reliable use.

When reheating is needed, the user can easily and quickly re-energize. The heat-storable electric heating shoe according to the present invention is convenient, fast, safe and reliable, simple in production technology, and low in cost. Its heat preservation effect Good, long heat preservation time, can be widely used in industry, agriculture and civil etc. Although the preferred embodiments of the present invention are described in conjunction with the drawings, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the present invention.
