Abstract

The utility model relates to novel warm-keeping shoes, which are suitable for cold weather. The warm-keeping shoes are improved on the basis that common shoes cannot keep warm. The design solves a series of problems of the common shoes that: the warm-keeping effect is poor, the water-preventing and ventilating cannot be realized, the temperature in the shoes cannot be automatically controlled and the like. The warm-keeping shoes are characterized in that: a temperature control circuit is arranged under an insole (10); the temperature in the shoes are detected by a temperature detecting circuit; a critical temperature point is preset by the temperature detecting circuit; when the temperature in the shoes is detected to be lower than the critical point by the temperature detecting circuit, a switch (K2) is controlled by voltage and a circuit of a heating element (11) is switched on, thus promoting the heating element (11) to emit heat; when the temperature in the shoes is higher than the critical point, the circuit of the heating element (11) is switched off by a touch switch (K1), thus leading the heating element (11) to stop emitting heat, and keeping the temperature in the shoes in a certain comfortable range. As the fabric of the insole (10) adopts nano materials, the warm-keeping shoes also have the characteristics of uniform heat emitting, good warm-keeping effect, good ventilating and water preventing.

Description

Novel warming shoe

Affiliated technical field:

The design relates to footwear, particularly controls the warming shoe field of heater heating automatically.

Technical background:

At arctic weather, people wear general shoes can feel very cold, and foot also can get chilblains when serious, and is very uncomfortable, influenced people's life, working and learning; Along with the raising of social life quality, people are also growing to the healthy attention degree of individual, and to the also raising day by day of love degree of pin, at arctic weather, pin is the same with hand easy to be ice-cold; Though existing warming shoe has solved warming problem, there is many-sided deficiency, such as, heating efficiency is not high, and warming effect is bad, and a lot of warming shoes are as long as a logical heating that powers on and will not stop, electricity wasting so very, temperature is too high sometimes also can injure pin, unfavorable to foot; Also have the warming efficient of some warming shoes not high, can not waterproof, can not breathe freely, can not control shoe temperature automatically.

Summary of the invention:

The purpose of this utility model is the defective that overcomes prior art, and a kind of novel warming shoe is provided.

Technical scheme: this designs by upper of a shoe 7, shoe-pad 10, and sole 8, temperature sensing circuit, voltage cut-out K2, lead 12, soft-touch control K1, power supply E constitutes.

The external structure of the utility model warming shoe: 14 the usefulness nanometer is heat insulating material formed encases in upper of a shoe of upper of a shoe 7 outer 13 and the upper of a shoe cun, and some silk flosses are put in the centre.Heater 11 is polytetrafluoroethylene (PTFE) electricity plastics, its good electrical property, and dielectric constant and the dielectric loss of polytetrafluoroethylene (PTFE) in wider frequency range is all very low, and specific insulation and arc resistance are all higher.

The internal structure of the utility model warming shoe: heater 11 is connected with voltage cut-out K2 by lead 12, and voltage cut-out K2 is connected with operational amplifier 6 on the temperature sensing circuit, and temperature sensing circuit connects the positive and negative polarities of power supply E; Shoe-pad 10 is made up of the two-layer heat insulating material formed and heater 11 of up and down a, b, have on lower floor is heat insulating material formed one with the equirotal openning of groove, She Ji purpose is in order to make easier induction heater 11 variation of temperature of temperature inductor R1, the temperature of sensing to be expressed accurately like this.Voltage cut-out K2 is a prior art, on market, can reach, temperature-control circuit and voltage cut-out are fixed on 15 li of sole grooves.

Temperature sensing circuit is by sensitive regulon, the memory storage unit, and voltage comparator circuit and power supply are formed, and sensitive regulon is composed in series by two resistance, and the memory storage unit is made up of diode and capacitances in series, and voltage comparator is made up of arithmetic unit.

Temperature sensor R1, resistance R 5, R3 pick out from positive supply E series connection, be added to the positive terminal of diode 2 at the B of resistance R 3 point current potential, diode 2 series capacitance C, soft-touch control K1 is connected in parallel on the two ends of capacitor C, and arithmetic unit amplifier 6 is connected into the voltage follower mode, its input termination capacitor C, output termination voltage cut-out K2, voltage cut-out K2 connects shoe-pad 10.The negative terminal connecting resistance R3 of power supply E, capacitor C, soft-touch control K1.As shown in Figure 2.

The course of work of temperature sensing circuit: after shoe temperature rises, temperature sensor R1 resistance changes, cause that operating point B current potential raises, the memory storage unit recovers to follow the tracks of the input that keeps the corresponding high potential of B point and send into operational amplifier 6, the current potential that A is ordered is directly sent into the other end of operational amplifier 6, the voltage comparator of operational amplifier 6 formations compares the potential difference between A, the B point thus, the signal of telecommunication is transferred to voltage cut-out K2, receive low-voltage, impel the disconnection of internal switch, make heater 11 stop heating.When shoe temperature drops to when preestablishing temperature, cause the decline of A point current potential, and certain voltage difference when taking place in the current potential of ordering with B, voltage comparator is a high potential with the electronegative potential high jump, voltage cut-out K2 receives the signal of telecommunication, the closure of trigger voltage gauge tap K2 internal switch makes heater 11 heatings.Too high when heating a period of time sensation shoe temperature, can stop heating by being located at the soft-touch control K1 of heel of a shoe inboard.Soft-touch control K1 is located at the inboard of footwear, and bipod is passable a little at a touch.In implementation process, the design temperature critical point is a certain value, when temperature-control circuit detects temperature and is lower than this critical point, impels heater 11 heating heat radiations, when temperature-control circuit detects temperature and is higher than this critical point, impels heater 11 to stop heating.Carry out so repeatedly, keep shoe temperature in certain temperature range, to change, make the pin can be not too high and uncomfortable because of shoe temperature, and less demanding to power supply E, longer than the power using time that uses same cost, saved resource.And present technique adopt heat insulating material formed be novel nanometer technology, warming effect is more superior, the shoe-pad 10 that is made into it is ventilative good, thereby is preventing that pin from can play certain effect on smelly.

Power supply E adopts high cumulative charged lithium cells.Battery is placed in the heel, one slot is set in the heel, various circuit are completed in advance, expose two contact points, be complementary, two elastic hooks are set in the heel again with the positive and negative polarities of power supply, the two-phase corresponding groove is set on power supply, design makes things convenient for picking and placeing of power supply E like this, has the charger of adapter in addition.The lining of shoe-pad 10 adopts nano material, has heating evenly, good warmth retention effect, ventilative and waterproof effect.

Advantage and characteristics:

1: heating is even, and good warmth retention effect is ventilative.

2: the integral body of footwear all adopts novel nano-material, and whole footwear can play waterproof effect.

3: heating temp can be controlled, and puts on comfortablely, saves.
