Description

The electric heating shoes of eddy-current heating

Technical field

The utility model relates to a kind of electric heating shoes that heats by way of electromagnetic induction.

Background technology

Electric heating shoes is the insulating product of using winter.Be mainly used in the area that does not have the warming equipment of air-conditioning, electric heating shoes is little because of volume, easy donning, and power consumption is little, and is extensively popular with users, Midwest and south in China, winter is as old man, patient, student, housewife's warming equipment.

Popular electric heating shoes divides according to power supply mode on the market now, and can be divided into two classes: a class is battery powered electric heating shoes, and another kind of is the electric heating shoes of using mains-supplied.

This two classes electric heating shoes cuts both ways, the great advantage of battery powered electric heating shoes is a safety, the user can freely-movable, but caloric value is little, frequent charge, at every turn charge limited, battery cost height service time, increase footwear body weight etc., all be its weak point; With the electric heating shoes of mains-supplied, have good heating effect, can prolong arbitrarily service time, and shortcoming is to have the civil power high pressure in the footwear body, and when footwear body wearing and tearing, or in footwear when moist, electric leakage is easily gently then got an electric shock, and is heavy then cause the personal safety problem; In addition, shoes must be changed during use, also inconvenience activity can not be moved.

Therefore, a kind of safe, efficiently, electric heating shoes is the urgent need in market easily.

Summary of the invention

The purpose of this utility model is to make a kind of electric heating shoes that generates heat by electromagnetic induction.It mainly is made up of electrical energy transmitter and heating footwear etc., and transmitter separates fully with the heating footwear.During use, the heating footwear are placed on the top of transmitter.In the heating footwear heater is arranged, it is a sheet metal, and it can receive electromagnetic energy and form eddy current, produces heat.

Electrical energy transmitter is to convert electrical energy into electromagnetic wave by the VOX series electric energy transmitter module of a special use and a LC resonant tank to launch; As the sheet metal (being heater) that energy receives, place the electromagnetic field of transmitting coil, the reception electromagnetic energy forms eddy current and generates heat.

Usually, electric heating shoes always uses in pairs, in every footwear a heater must be arranged respectively, therefore, the electric energy radiating portion must be with two transmitting coils, and two coils can serial or parallel connection, formation LC resonant tank in parallel with electric capacity then, two heater power supplies about two coils are respectively.

If fixing temperature is arranged in the assurance footwear, must in every footwear, increase a temp control switch, when temperature reaches set point, reduce the caloric value of heating sheet automatically, to realize the purpose of temperature control.Implementation method is that heater is made the open loop shape, connects temperature detect switch (TDS) at opening part.

Adopt the electric energy emission IC of VOX series, it can be converted into magnetic energy with electric energy, launches by coil.It need provide two voltages, and one is the driving voltage of chip, can be by obtaining behind the rectifying and wave-filtering after the civil power step-down; Another is that LC launches needed emission voltage, can directly or after isolation or the transformation, be obtained behind the rectifying and wave-filtering by civil power.

The beneficial effects of the utility model are: because electrical energy transmitter is separated fully with the heating footwear, guaranteed the independence and the freedom of two footwear bodies, also guaranteed the security of electric heating shoes, flexibility and comfortableness can ensure user's personal safety fully.This electric heating shoes can use in warming shoe, also can leather shoes or other footwear in use, therefore, city shoe also can become electric heating shoes, and needn't change shoes when using.

The specific embodiment

Electrical energy transmitter shown in Fig. 1, transmitting chip IC1, emission resonant capacitance C1, left side transmitting coil L1A and right transmitting coil L1B series connection, these four elements have been formed the radiating portion of electric energy, and electric energy is converted into magnetic energy outwards to be launched, and transmit direction is perpendicular to coil plane.At this moment,, will receive electromagnetic energy in the sheet metal and form eddy current, thereby make the sheet metal heating if in this magnetic field, put into a sheet metal.Sheet metal places footwear inside, and when the sheet metal adstante febre, the footwear body is along with heating.Left side transmitting coil L1A makes left footwear fever, and right transmitting coil L1B makes right footwear heating.

Transmitting chip IC1 is special-purpose VOX series electric energy transmitter module (as VOX330MP05S, VOX12MP05 etc.), and it can be converted into magnetic energy with electric energy, launches by left transmitting coil L1A and right transmitting coil L1B.It need provide two voltages, and one is the driving voltage 9-12V of chip, can be by obtaining behind the rectifying and wave-filtering after the civil power step-down; Another is that LC launches needed emission voltage (400V following), can directly or after isolation or the transformation, be obtained behind the rectifying and wave-filtering by civil power.

Further specify below in conjunction with example.

Fig. 2 is the scheme of installation of electrical energy transmitter.After left side transmitting coil L1A and the right transmitting coil L1B series connection (or in parallel), place between base plate A1 and the panel A2.Left side transmitting coil L1A has identical parameter with right transmitting coil L1B, comprises inductance value and Q value etc., and during installation, two coils are line of symmetry with the center line of base plate A1, lay respectively at the both sides of center line; Base plate A1 and panel A2 must be insulation, waterproof, high-intensity high-abrasive material, and thermal conductivity is preferably arranged, and gather to prevent internal heat.
