Abstract

The utility model relates to a thermostatic electric heating sole, which mainly comprises an outer bottom, batteries in a battery cabin on the heel part of the outer bottom, and a heat conducting layer which is arranged on the upper surface of the outer bottom and is clamped between the upper and the lower metal thermal fins on the front and the rear parts of vola; PTC heating blocks which are dispersed in through holes of the heat conducting layer are used as a heating element, a constant temperature state in the shoes is kept by utilizing a thermostat which is arranged between the PTC heating blocks and the batteries, and the thermostat is connected with the PTC heating blocks and the batteries. The utility model has the advantages of less power consumption, energy saving, and long service life.

Description

The constant temperature electric heating sole

The utility model relates to a kind of sole, particularly a kind of warming constant temperature electric heating sole of foot that makes.

The warming shoe of Chu Shouing as cotton leather shoes, cotton-padded shoes etc., himself does not have heater in the market, cold season, the invasion and attack that rely on the heat insulating ability of foot self temperature and footwear to resist extraneous cold temperature fully.Because the heat-insulating property of these footwear is relatively poor, concerning the workman of long-term operation in the open air and keep the soldier on limit, be difficult to guarantee that foot do not suffer from cold and frostbite.And disclosed electric heating shoes patent mostly adopts heating wire as heater element, because the heating wire frangibility, so its service life is shorter.Particularly the power consumption of heating wire is bigger, the also corresponding increase of use cost.In addition, now the electric heating shoes of public offering can not be realized automatic outage because of there not being attemperating unit when shoe temperature is higher, makes the wearer be difficult to adapt to, but also wastes electric energy.

At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of thermal property height and long service life, little, the energy-conservation constant temperature electric heating sole of power consumption.

The purpose of this utility model is achieved in that it comprises outer bottom and the battery that is located in the outer bottom heel institute charged pool storehouse, it is characterized in that: the outer bottom upper surface the front and rear of sole be provided with respectively be held on the heat-conducting layer between the upper and lower metal fin and be embedded in heat-conducting layer with the heating of the PTC in through hole block, be positioned at sole middle part at the outer bottom upper surface and be provided with the heat-conducting metal net that heat conduction is used, PTC heating block links to each other with battery in the battery compartment by lead.

In order to keep being in preferable temperature constant state in the footwear, between PTC heating block and battery, a temperature controller is set, when shoe temperature reached temperature required, PTC heating block cut off the power supply automatically, otherwise, automatic the getting of PTC heating block.

The utility model has the advantages that: utilize PTC heating block as heater element, not only power consumption is little, and not fragile, long service life, the temperature controller of setting up between PTC heating block and battery not only helps keeping being in temperature constant state in the footwear, and helps saves energy.

Below in conjunction with accompanying drawing the utility model is explained.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A view among Fig. 1.

Fig. 3 is the utility model circuit theory diagrams.

By accompanying drawing as can be known, this constant temperature electric heating sole mainly comprises outer bottom 1 and is located at the battery 9 in the outer bottom 1 heel battery compartment 8 and is located at outer bottom 1 upper surface and is held on heat-conducting layer 5 between the upper and lower metal fin 3,4 in the sole front and rear portions, the front and back heat-conducting layer with through hole in be inlaid with PTC heating block 2, this heating block links to each other with battery 9 by temperature controller 7 (SL-48 ℃) with lead, be positioned at the sole middle part at outer bottom 1 upper surface and be provided with the heat-conducting metal net 6 that heat conduction is used, this position is because of easy to break, so do not establish metal fin.And heat-conducting metal net frangibility not, the somewhere was fractureed does not influence its conduction heat yet.Sequence number 10 is the battery compartment lid among the figure, and sequence number 11 is a charging socket.

Claims

1, a kind of constant temperature electric heating sole, it comprises outer bottom and the battery that is located in the outer bottom heel institute charged pool storehouse, it is characterized in that: the outer bottom upper surface the front and rear of sole be provided with respectively be held on the heat-conducting layer between the upper and lower metal fin and be embedded in heat-conducting layer with the heating of the PTC in through hole block, be positioned at sole middle part at the outer bottom upper surface and be provided with the heat-conducting metal net that heat conduction is used, PTC heating block links to each other with battery in the battery compartment by lead.

2, constant temperature electric heating sole according to claim 1 is characterized in that: between PTC heating block and battery a temperature controller is set.
