Abstract

The present invention relates to an automatically ignited candle which comprises an electric heating wire type electronic ignitor. The candle comprises a 3V power supply, a hand-operated switch and a sound controlled switch. In the present invention, a layer of antimony trisulfide and a layer of potassium chlorate are coagulated on the surface of an electric heating wire rapidly burnt to turn red after the power supply of the candle is switched on, the antimony trisulfide and the potassium chlorate on the surface of the electric heating wire also reach an ignition point since the antimony trisulfide and the potassium chlorate are heated, and thereby, an open flame is generated to ignite the candle. The electric heating wire type electronic ignitor is mainly used for the ignition of birthday candles.

Description

Automatically ignited candle

The present invention relates to a kind of automatically ignited candle of forming by nichrome wire formula ignition.

In the present prior art, nichrome wire formula ignition all is independent use basically.As the no flame wind-proof type electronic lighter of being sold on the present market, just said nichrome wire formula electronic lighter also has nichrome wire formula electric furnace etc.They have only played the effect of transmitting heat after energising, all directly do not produce naked light.

Task of the present invention provides a kind of simple in structure, the automatically ignited candle that cost is low.Present nichrome wire formula ignition does not all directly produce naked light after energising.

Automatically ignited candle of the present invention is the power supply by 3V, a manual switch, an audio-switch, the circuit that candle and ignition are formed.The power supply of 3V is made up of two batteries, and manual switch is a power switch total in the circuit, and it is connected on the back of 3V power supply, is to be used for avoiding causing unnecessary loss owing to extraneous vibration, sound etc. make audio-switch by the random power supply of connection automatically.Audio-switch is one and after manual switch is connected power supply, reaches a kind of switch of automatic connection power supply by sound, vibration according to human needs that it is connected on the back of manual switch again.Candle then is connected on the back of audio-switch, the inside and top at candle, the electric wire size of using is the same, two wires of its inside are very thin iron stamen line, using thin iron stamen line is in order not allow iron stamen line occupy the area at tiny candle inside and top, and it is attractive in appearance to influence the candle top, so the electric wire at candle the inside and top is thin more good more, but can not be less than the ability to bear of ignition applied voltage.Candle is in combustion processes, and two iron stamen lines of candle the inside also can burn, and the insulation layer of iron stamen line is generally made with polyvinyl chloride, so it at incendiary simultaneously, also will emit harmful and poisonous gas.So the present invention removes the iron stamen line insulating layer at candle the inside and top, adopts the sort of wick line of using in the candle, and it is swathed separately.At the top of candle, be provided with an ignition, the employed nichrome wire material ranges of this ignition is very wide, uses so long as the rubescent metallic substance that can generate heat after energising all can be used as nichrome wire.In making processes, of nichrome wire is fixed on positive pole, the other end is fixed on negative pole.Because present nichrome wire formula ignition does not all directly produce naked light in energising, so in technical solution of the present invention, adopt surface solidification last layer antimony trisulfide and Potcrate at nichrome wire.When the power supply of candle was switched on, the nichrome wire of ignition was also just burnt red, and antimony trisulfide and Potcrate have also just reached point of ignition, so also just produced naked light, candle has also just been ignited simultaneously.In order to increase the success ratio of ignition, in ignition, set up one nichrome wire again, and again at surface solidification last layer needle antimony and Potcrate, ignition also just had double shield in the process of igniting like this.In the candle process of igniting,,,, also easily extinguish sometimes even ignited so the candle wick is difficult for being ignited when igniting because the wick line of candle is a line matter.Therefore, the position of igniting of candle top wick line is soaked into paraffin and rosin.Encase together with antimony trisulfide and Potcrate wick line and twice nichrome wire again, make a circle the candle top, in the time of can making the candle igniting like this burning more prosperous, can make the top attractive in appearance solid again, form an integral body.

Since this nichrome wire in surface solidification one deck antimony trisulfide and Potcrate, thereby the nichrome wire that makes this ignition energising and burnt rapidly red in, antimony trisulfide that it is surperficial and Potcrate also with regard to reached point of ignition because of being heated, have produced naked light therefrom.

The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments

It shown in the figure schematic circuit of the present invention

Automatically ignited candle circuit as described in Figure, it is the power supply by 3V, a manual switch, an audio-switch, candle and ignition are formed.Want automatically ignited candle igniting, at first will open manual switch, connects total power supply, and then clap or by other sound, the vibration grade makes audio-switch connect power supply automatically with hand, at this moment the power supply of candle also just has been switched on.In two supply leads below candle, one is connected on positive pole, and one is connected on negative pole.At the inside and the top of candle, the diameter of two wires is 0.15 millimeter, and no polyvinyl chloride insulation layer swathes it with the wick line separately, to replace insulation layer.Like this when candle combustion, just can be because of the heat transfer of iron stamen line yet, and with inner boiling hotization of candle, be out of shape.Top at candle, what ignition adopted is two road nichrome wire, one be connected on negative or positive electrode above, the other end is connected on below negative pole or the anodal, wherein one nichrome wire is connected on the front, another road is connected on the back side, their arranging of formula of staggering, and at the surface solidification last layer antimony trisulfide and the Potcrate of twice nichrome wire.Wick line place at the candle top, with paraffin and rosin lamp line is soaked into, last be set in together with antimony trisulfide and Potcrate twice nichrome wire and the wick line with the top again, whole like this candle top is exactly an integral body, both attractive in appearance, burning is more prosperous in the time of making the candle igniting again.In optimum implementation of the present invention, the metallic substance that nichrome wire adopts is a steel wire, because the fusing point of steel is lower, so its power consumption is also just less relatively, steel has not only hard but also toughly in addition, withstands big pressure, stands the advantage of big pulling force.The length of nichrome wire should be less than 20 millimeters, and its power consumption and heat transfer are directly proportional with length, and power consumption is just few more more in short-term when length, and it is just fast more to conduct heat.The size of nichrome wire is relevant with candle top electric wire size, and in a kind of metallic substance, the cross-sectional area of candle top electric wire must be more than or equal to 2.5 times of nichrome wire cross-sectional area.Only under this ratio situation, heat-transfer effect the best of nichrome wire, and its power consumption and conducting heat also is directly proportional with the section area size, when the cross-sectional area of nichrome wire more hour, its power consumption is just few more, it is just fast more to conduct heat, and also just is easy to be burnt red.

Since in the surface solidification of nichrome wire one deck antimony trisulfide and Potcrate, so after candle is connected power supply, nichrome wire will be burnt red rapidly, and the antimony trisulfide on nichrome wire surface and Potcrate have also just reached point of ignition because of being heated, so also just produced naked light, candle has also just been ignited simultaneously.Because the wick line is to have soaked into paraffin and rosiny,, burns easily and go below the lamp line of wax so that candle wick line can burn when being ignited is more violent.
