CN2321259Y - Warm keeping shoes - Google Patents

Abstract

The utility model relates to a pair of heated warm keeping shoes with low voltage power supplying. The warm keeping shoes are composed of insteps, warm keeping material layers of the insteps, soles and the warm keeping material layers of the soles, wherein the front part and the underside of the feet part of each of the soles are respectively provided with a heater and a conducting strip, and a heel of each of the shoes is provided with a battery box, an interface of an external power supply and a power switch. The heater is a kind of ceramic (PTC) heating material with the positive temperature coefficient. The heated warm keeping shoes especially adapt to be worn in the cold environment outdoors. When the power supply is switched on, the produced heat can heighten the skin temperature of the toes and accelerate the blood circulation of the feet, which can improve people's cold hardiness ability in the cold environment.

Description

A kind of warming shoe

The utility model relates to a kind of warming shoe, particularly a kind of low-voltage of using, the hot type warming shoe that direct current supply is safe and reliable.

Footwear are indispensable apparatus of wearing in people's daily life, and particularly in cold environment, people's tolerance time length depends on the thermal property of footgear to a great extent.Foot particularly toe is that human body be cannot say for sure the position of warming up most, this is difficulty because the backflow heart of lower limb blood need overcome the effect of gravity, the activity of toe is very little again, so even the warming amount at other positions such as trunk is enough, the skin temperature of toe also can be because of warming bad the reduction, below the toe skin temperature drop to 5 ℃, severe pain is reduced to below-4 ℃ unbearably, the situation of frostbite will occur.Present warming shoe only adopts passive insulation effect, can not guarantee the antifreeze of foot, even the military wool shoe of warming value about up to 2 Crows, in-30 ℃ cold environment, wearing it after 1 hour toe also can severe pain unbearably.The electrically heated warming shoe of civilian interchange that China's patent 93206825.1 a kind of usefulness of introducing is common, its shortcoming is that it must have lead to connect, be confined to use in the conductor length radius region, be difficult to be implemented in cold outdoor free activity, and because the higher meeting of supply voltage brings hidden danger to the people.

The purpose of this utility model is to provide a kind of hot type warming shoe with the low voltage and direct current power supply, and it can make the warming of human foot effectively, prolongs the tolerance time of people in cold environment; The hidden danger of aforementioned Heating insulation shoe and the restriction of zone of action have been eliminated simultaneously again.

The purpose of this utility model is achieved in that at the warming shoe sole forepart and is provided with groove near the toe place and near place, arch of the foot spring acupuncture point that a calandria is installed respectively, and being close to respectively has a conducting strip on the calandria; Be provided with groove at the heel position, battery case is installed; Have two apertures at the heel medial surface, power switch and external direct current power supply socket are installed respectively; The wire casing that above-mentioned each parts are reserved by sole connects with lead.Described calandria is a kind of positive temperature coefficient ceramic (PTC) heating material, this material be the mixture by barium strontium titanate and strontium barium niobate when constituting its room temperature resistance be 15-25 Ω, all can operate as normal under the 3-24V DC voltage.Behind power connection, the heat that calandria produced is by the conducting strip conduction and be radiated to toe and arch of the foot position, to promote the increase of foot's VPV, improves toe skin temperature to comfort temperature, thereby reaches the warming purpose of human foot.

Owing to the utlity model has special structural design and adopt novel heating material.So have the advantage of aspects on the implementation:

1. the utility model is easy to use both can be with 3 joint common batteries or rechargeable battery powered, in outdoor application; Also can externally import, reduce use cost, in indoor or mobile automobile, use.

2. the calandria that the utility model adopted, has quick heating, heat loss is few, it is effective to heat up, under the powered by direct current of 3-12V voltage, the calandria Curie temperature just can reach 30-80 ℃ in 10 minutes, and the conducting strip surface temperature is at 25-70 ℃, can make 10-30 ℃ of toe skin temperature rise, to reach comfort conditions.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a body cutaway view of the present utility model.

Fig. 2 is a sole vertical view of the present utility model.

Following specific structural features and the working condition that the utility model proposes that illustrate in conjunction with the embodiments with reference to accompanying drawing.

Referring to Fig. 1, shown in Figure 2, the utility model master protects dim material layer 3, the heat insulating material formed layer 2 of sole and sole 1 by vamp 4, vamp and forms.Described sole 1 is provided with three difform grooves, calandria 11, conducting strip 12 are installed respectively, calandria 13, conducting strip 14, battery case 18, heel medial surface at sole 1 has two apertures, power switch 16, external power interface 17 are installed respectively, and above-mentioned each parts connect into a loop by lead 15.It is characterized in that described calandria 11,13 is round ceramic (PTC) sheet, be that mixture by barium strontium titanate and strontium barium niobate constitutes, resistance 15-25 Ω during its room temperature, conducting strip 12 is a cashew nut shape heat conduction copper sheet, conducting strip 14 is circular heat conduction copper sheet, battery case 18 can be placed side by side No. 5 batteries of 3 joints, power switch 16 can break-make power supply saves energy, external power interface 17 can insert low-voltage dc power supply.Behind power connection, calandria 11,13 heats that produced are respectively by conducting strip 12,14, with conduction and the mode of radiation to person's toe position and arch of the foot position transfer of heat, its skin temperature is gone up rapidly to comfort temperature, help the blood circulation of human body foot in cold environment simultaneously, strengthen the human body cold tolerance.When foot feels overheated, but powered-down switch 16 quits work.

Claims (3)

1. low voltage power supply hot type warming shoe, calandria (11), (13) are housed on the sole of described warming shoe, be close to a heat conduction copper sheet (12), (14) are respectively arranged on the calandria, battery case (18), power switch (16) and external power interface (17) are housed at its heel place, be linked to be an integral body by lead (15) between them, it is characterized in that calandria (11) and conducting strip (12) are installed in is close to people's toe position, and calandria (13) and conducting strip (14) are installed near place, people's arch of the foot spring acupuncture point.
