Abstract
The utility model relates to a pair of rechargeable electrothermal shoes. The sole of each shoe is provided with a heat generating system composed of a plurality of in parallel arranged PTC elements which are connected by conducting wires and switches, and a discharging and charging circuit formed by low-voltage rechargeable power supply and a rechargeable jack. The PTC element becomes hot when the switches are connected, so the temperature in shoes raise to a degree and then the shoes are kept in constant temperature state. The rechargeable electrothermal shoes provided by the utility model has simple structure, can be used for heating without influencing wearing and walking, and can be used in leather shoes, travel shoes and heat insulating shoes in winter.
Description
The utility model relates to a kind of electric heating shoes, and particularly a kind of the dress fitted the electric heating shoes that relaxes.
The shoes that generally use constitute the no heating of footwear system itself by sole, vamp and necessary shoe-pad now.A kind of multifunction electric hot shoe that China's patent 89202421.6 is introduced, under 220 volts of alternating voltages, work, during user mode, attaching plug is inserted supply socket, then both feet are put into boots, gauge tap pulls out top grade, switch is pulled out low-grade when feel is moderate to temperature or turns off, and reaches the effect of heating.This multifunction electric hot shoe must generate heat under energising (220 volts) state, can only staticly use, and be not suitable for outdoor dress, and the boots specification is big, and (300 * 260 * 240mm), easy burn-out makes simultaneously the people produce a kind of sense of insecurity.
At above-mentioned defective, it is a kind of simple in structure, easy to use that the utility model provides, and can control constant temperature automatically, and do not lose a kind of electric heating shoes of conventional shoe function again.
The electric heating shoes that the utility model provides is achieved in that in common footwear to be provided with heat-generating system that heat-generating system is connected and forms with switch with lead with the PTC element by the low pressure charge power supply.With lead low pressure charge power supply and charging jack are linked to be a charging circuit in addition.When user mode, open switch, power supply and PTC element switches, according to the characteristic of PTC element, the PTC element heating, temperature is risen, when arriving the Curie-point temperature of PTC element, the resistance value of PTC element is anxious to be increased, and output current is die-offed, caloric value is descended, temperature descends thereupon, and when dropping to Curie-point temperature when following, resistance value diminishes, output current increases, PTC element heating amount increases again, and temperature rises, and the temperature of this PTC element is controlled at about Curie-point temperature automatically thus, the basic temperature constant state that keeps plays warming effect.Closing swap switch during non-working condition gets final product.When the low pressure charge power supply need be charged, close swap switch, the output of the low-voltage DC that obtains after 220 volts of alternating current transformations and rectification is inserted the charging jack, promptly chargeable.Can use after the power source charges, but low pressure charge power supply recharge is more than 500 times.
The electric heating shoes that the utility model provides, its mesolow charge power supply is selected the low-voltage direct charge power supply for use, and voltage is 3～36 volts, can be in series with the above DC charging battery of 3 joints, preferably selects for use 3 joint 1.2V rechargeable batteries to be in series; It is 20 ℃～50 ℃ PTC element that the PTC element is selected Curie-point temperature for use, preferably 30 ℃～35 ℃ PTC element, and the number of PTC element is more than 1, the shape of PTC element is advisable to be fit to install and do not influence dress, be preferably button-type, thickness is 3mm, and diameter is 20mm.
The electric heating shoes that the utility model provides, its heat-generating system can be arranged on any suitable position in the footwear, preferably are contained on the sole, and heel portion is installed the low pressure charge power supply, and first half is installed the PTC element, and rationally distribute.Again the chassis plate made from the hard material of good heat conductive performance is covered on the sole, chassis plate and sole are combined into one with pasting glue or shoe tack.
The electric heating shoes that the utility model provides, the switch that wherein is attached in the heat-generating system can adopt pressure sensitive switch, produces pressure in wearing footwear PTC element and power circuit are connected; When taking off shoes, pressure disappears, and circuit disconnects.Also can use regular tap, stay a power switch hole on chassis plate, in the time of using, earlier switch be got to out shelves, circuit is connected, and puts on shoes; After taking off shoes, switch is got to the pass shelves, circuit disconnects.On chassis plate, also stay a hole, use for low pressure charge power supply charging jack.
The electric heating shoes that the utility model provides, the charger of power supply source charging usefulness can be special-purpose, also the transformation rectifying power supply apparatus that can use with existing pocket radio cassette player.When special-purpose, as long as form a transformation rectifying circuit device with transformer and rectification diode, make 220 volts of alternating voltage transformations be rectified into low-voltage dc voltage, its output inserts the charging jack and gets final product.
The electric heating shoes that the utility model provides, it is when using 1.2 volts of rechargeable batteries of three joints to be composed in series power supply, peak power output can reach 4W, when the temperature of PTC element arrives Curie-point temperature, when being in basic temperature constant state, consumed power is little, the once sustainable use of power source charges is about 6 hours, when the PTC element is arranged at sole, can rationally distribute by the main acupuncture point of sole, can play a role in health care.
The electric heating shoes that the utility model provides, its circuit are that the positive pole of power supply divides two-way after being connected by battery: the one tunnel connects switch connects each PTC element in parallel again; Arrive negative pole again; Another road connects charging jack negative pole, and the positive pole of charging jack is received the negative pole of power supply again.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.
With reference to Fig. 1, sole is divided into sole (7) and base (3) with heat guard (9).Below the heel portion of base (3), fixed installation 3 joints have the rechargeable battery (4) of 1.2 volts of better performances, with contact (12) 3 joint rechargeable battery series connection are linked, and charging jack (10) and rechargeable battery (4) are linked to be a charging circuit with lead (11).5 Curie-point temperatures of first half fixed installation at base (3) are the PTC element (5) of 30 degree, and one of them PTC element is the position of Yongquan acupoint under foot, and PTC element (5) is selected button-type for use, and diameter is 20mm, and thick is 3mm.With lead each PTC element is connected in parallel, is connected through the both positive and negative polarity of switch again with power supply (4).Chassis plate (2) leaves seven holes, and one is charging jack usefulness, and one is switch usefulness, and five is that the position of PTC element is over against locating.Again this chassis plate (2) is overlayed on the base (7), with shoe tack chassis plate (2) and base (7) are fixed again.
When user mode, open switch (6), connect power supply, make the PTC element heating, rise to Curie-point temperature through short period PTC component temperature, promptly arrive the basic temperature constant state that keeps of control automatically.The heat that the PTC element sends passes on the pin by chassis plate (2) and liner (cloth matter) (1), makes pin warm, and general sustainable about 6 hours of temperature constant state is up to stop heating when running down of battery PTC element.In the time of obsolete, as long as close swap switch (6), rechargeable battery (4) exhausts when needing charging, switch (6) is in turns off the position, the output that reaches 4 volts dc source after transformation and rectification is made circular plug, insert charging jack (10), promptly chargeable.Can reuse after the charging.
