Description
Technical field
The utility model relates to a kind of blind person's hand warmer.
Background technology
Plug and socket is the electricity consumption coupling device widely used during people live. The technology of plugs and sockets is very ripe, but concerning the elderly of blind person, Disabled persons and visual deterioration, or some wretched insufficiency part. Electricity is commonly called as " tiger ", will breed disaster with careless slightly in electric process. But blind person because of visual problems because of carelessness touching can cause great accident that it shines into injury.
Owing to the copper sheet of plug head is outer exposing outside, the copper sheet on plug must could insert in the hole on alignment socket, concerning eye illness person, visual deterioration old man and blind person, is a very difficult thing by plug insertion socket. One usually being adopted to seem that very the guidance method blind person of " effectively " touches the method for braille at present, with a finger " navigator ", after having touched the jack on socket, plug is injected jack by another hand. When the copper sheet on plug contacts with the copper sheet in jack, when the finger of " navigator " does not also leave socket, electric shock accident is it is possible to there occurs.
Existing socket for blind men continues to use plastics or metal epirelief point, "ON" and "Off" in the switch use braille system of socket at the outer of common socket. During use, blind person touches switch along the convex point of socket outer, by the braille touched on blind person's switch, blind person just knows what state switch is in, if that opens then shuts it, then can safety, relieved plug is injected socket, open switch again, so that it may to employ.
But also being far from solving concerning danger blind person on this basis, blind person still directly removes contact power supply with hand, and this wherein also also exists and dangerous does not solve. In China more than 1,200 ten thousand blind persons, understand braille less than 10%. So existing socket for blind men does not have too big meaning for most of blind person.
Practical novel content
For problems of the prior art, the purpose of this utility model is to provide the technical scheme of a kind of blind person's hand warmer.
Described a kind of blind person's hand warmer, it is characterized in that comprising hand warmer body and heating unit, heating unit comprises magnetic electricity converting electrical energy and accepts module, PTC thermistor and heating module, and magnetic electricity converting electrical energy accepts module, PTC thermistor and heating module and forms loop;The two ends that magnetic electricity converting electrical energy accepts module arrange fusible cut-out, and the two ends of heating module are arranged in parallel power light.
Described a kind of blind person's hand warmer, it is characterised in that described heating module adopts electromagnetism heating arrangement, is made up of heater coil and iron plate, and iron plate contacts with the heating liquid in hand warmer body.
Described a kind of blind person's hand warmer, it is characterised in that described power light two ends are arranged in parallel hummer.
Described a kind of blind person's hand warmer, it is characterised in that described magnetic electricity converting electrical energy accepts module and matches with the electromagnetic switching device module without spring hole scoket.
The utility model working process: user by hand warmer near without spring hole scoket, produce induction electricity, magnetic electricity converting electrical energy accepts module and accepts magnetic field generation current, is sent to the inner circuit of hand warmer, and hummer is sounded, whether user learns putting position and charges, heating module starts heating, is heated to temperature of saturation because of the excessive turn-off current of resistance, and hand warmer stops heating, hummer cuts out sound, heats complete. Mainly it is supplied to blind person or amblyopia crowd use, when making blind person need not worry that hand warmer plug-in is heated again, there is safety problem.
Advantage of the present utility model:
1. hand warmer adopts inductance coupling electric energy type of transmission;
2. magnetic electricity converting electrical energy accepts module and coordinates with the electromagnetic switching device module without spring hole scoket, and magnetic electricity converting electrical energy accepts module installation in hand warmer, solves employing plug at present and charges and bring the problem of danger;
3. heating module adopts electromagnetism heating, safe and reliable efficiency height;
4. install hummer additional and can allow blind person is clear learns whether heating completes.
Accompanying drawing explanation
Fig. 1 is electrical block diagram of the present utility model;
In figure: 1-magnetic electricity converting electrical energy accepts module, 2-fusible cut-out, 3-PTC thermistor, 4-power light, 5-hummer, 6-heating module, 7-electromagnetic switching device module.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
A kind of blind person's hand warmer, this hand warmer with without spring hole scoket with the use of, the structure without spring hole scoket refers to 201420102644.7. The utility model comprises hand warmer body and heating unit, heating unit comprises magnetic electricity converting electrical energy and accepts module 1, PTC thermistor 3 and heating module 6, magnetic electricity converting electrical energy accepts module, PTC thermistor and heating module and forms loop, and magnetic electricity converting electrical energy accepts module and matches with the electromagnetic switching device module 7 without spring hole scoket. When hand warmer temperature is higher than set(ting)value, PTC thermistor disconnects, and disconnects heating circuit; The two ends that magnetic electricity converting electrical energy accepts module arrange fusible cut-out 2, play protection circuit effect, and the two ends of heating module are arranged in parallel power light 4, play the effect of prompting heating.
Heating module of the present utility model adopts electromagnetism heating arrangement, is made up of heater coil and iron plate, and iron plate contacts with the heating liquid in hand warmer body.
Using to be more suitable for blind person, be arranged in parallel hummer 5 at power light two ends, hand warmer position is with, when contacting without spring hole scoket, hummer sound production prompt blind person, reminds the particular location without spring hole scoket.
The utility model with without spring hole scoket with the use of, the charging part of electric hand warmer changes magnetic electricity converting electrical energy into and accepts module, when electric hand warmer is when without spring hole scoket, can rely on without the electromagnetic switching device module automatic absorbing in spring hole scoket in receptacle face, carry out the transmission of electric energy, thus hand warmer makes electrified regulation.The mode electric energy transmitting that this hand warmer is transmitted by inductance coupling electric energy, adopts the principle with electromagnetism heating to use magnetic field induction eddy current thermostatically heating principle simultaneously, is heated by heating liquid in hand warmer, better control temperature, ensure security.
When heater coil energising, heater coil produces high frequency magnetic field so that the iron plate being in heater coil is generated heat by magnetic field induction. Electric energy can be whole by the heat energy being converted into iron plate in said process, in whole process, iron plate and heater coil are without any physical contact, and the conversion of energy has been responded to by magnetic field eddy current and iron plate completely.
Circuit inside is provided with a PTC thermistor, and when temperature reaches set(ting)value time, hand warmer stops heating, and when lower than set(ting)value, heating is started working. Add hummer in circuit simultaneously, help blind person to learn and whether put whether seat correctly and has filled electricity with.
