Specifically, heat generating member 1 is usually alloy material, due to special-purpose of the heat generating member 1 in electronic cigarette, it must possess certain heat resistance, plasticity, weldability and toughness etc..Nickel is excellent resistant material, is important alloy element, and nickel can form Ovshinsky element of volume in Exothermal Alloys；Chromium is used as the alloying element in Exothermal Alloys, the paradoxical movement for promoting it internal develops in terms of being conducive to corrosion failure, chromium improves the electrode potential of iron-based solid solution, and the electronics that chromium absorbs iron is passivated iron, while effect of the nickel in Exothermal Alloys is just brought into play after coordinating with chromium；Carbon is the element of stable austenite, and the degree acted on is very big (about 30 times of nickel), and the affinity of carbon and chromium is very big in addition, the carbonization with chromium formation a series of complex
Thing, can effectively improve the intensity and corrosion resistant candle property of Exothermal Alloys；Silicon can significantly improve the elastic limit, yield point and tensile strength of Exothermal Alloys, and silicon and molybdenum, chromium etc. are combined, and Exothermal Alloys corrosion resistance and oxidation resistant effect are improved, while the heat resistance of Exothermal Alloys can be improved；In addition, p and ses are essential harmful debris in some alloys, as phosphorus can cause alloy " cold brittleness ", sulphur occur alloy can be caused " red brittleness " occur, due to reduction, the two content can improve process costs, the two can not be completely eliminated generally in specific implementation process, can only alap its content of reduction, or usually alleviate the two negative effect brought by adding other members within the specific limits；Manganese can slacken and eliminate the harmful effect of sulphur, manganese is similar to nickel for the effect of austenite, but the effect of manganese does not lie in form austenite, but be to reduce the critical quenching rate of Exothermal Alloys, increase the stability of austenite in cooling, suppress the decomposition of austenite, the austenite formed under high temperature is maintained to normal temperature and the quenching degree of alloy can be improved, manganese content very high alloy has good wearability and other physical properties；Iron is the necessary element of many alloys.The element of above-mentioned composition alloy respectively has its effect and purposes (or drawback), in order that Exothermal Alloys can finally realize specific application performance, the content of every kind of element must is fulfilled for certain proportioning, in this programme, the material of heat generating member 1 by weight percentage, including：0.02%~0.08% carbon (C), 0.05%~1% silicon (Si), 1%~2% manganese (Mn), 0.015%~0.045% phosphorus (P), 0.01%~0.03% sulphur (S), 16.5%~20% chromium (Cr), 8.5%~15% nickel (Ni), and iron (Fe).
In specific implementation process, the constituent of heat generating member 1 has following several situations：
1) heat generating member 1 is specifically included：0.02%~0.08% carbon, 0.05%~1% silicon, 1%~2% manganese, 0.015%~0.045% phosphorus, 0.01%~0.03% sulphur, 16.5%~18.1% chromium, 8.5%~15% nickel, and the percentage by weight for making heat generating member 1 overall reach 100% iron.Such as 0.03% carbon, 0.08% silicon, 2% manganese, 0.045% phosphorus, 0.03% sulphur, 17% chromium, 14% nickel.
2) heat generating member 1 is specifically included：0.02%~0.08% carbon, 0.05%~1% silicon, 1%~2% manganese, 0.015%~0.045% phosphorus, 0.01%~0.03% sulphur, 16.5%~20% chromium, 10.5%~14.5% nickel, and the percentage by weight for making heat generating member 1 overall reach 100% iron.Such as 0.08% carbon, 1% silicon, 2% manganese, 0.045% phosphorus, 0.03% sulphur, 19% chromium, 14% nickel.
3) in addition to above-mentioned material, heat generating member 1 also includes the molybdenum (Mo) of other materials, such as 2%~3.5%, molybdenum
The quenching degree and heat resistance of alloy can be significantly improved, temper brittleness is prevented, remanent magnetism and coercivity is improved, the weight ratio that now content of iron (Fe) can make composition overall reaches 100%.Specifically, heat generating member 1 includes：0.02%~0.08% carbon, 0.05%~1% silicon, 1%~2% manganese, 0.015%~0.045% phosphorus, 0.01%~0.03% sulphur, 16.5%~18.1% chromium, 10.5%~13.5% nickel, 2%~2.5% molybdenum, and the percentage by weight for making heat generating member 1 overall reach 100% iron；Such as 0.08% carbon, 1% silicon, 2% manganese, 0.045% phosphorus, 0.03% sulphur, 17% chromium, 12% nickel and 2.5% molybdenum.Or, heat generating member 1 is specifically included：0.02%~0.08% carbon, 0.05%~1% silicon, 1%~2% manganese, 0.015%~0.045% phosphorus, 0.01%~0.03% sulphur, 16.5%~18.1% chromium, 12.5%~14.5% nickel, 2%~2.5% molybdenum, and the percentage by weight for making heat generating member 1 overall reach 100% iron；Such as 0.03% carbon, 1% silicon, 2% manganese, 0.045% phosphorus, 0.03% sulphur, 17% chromium, 14% nickel and 2.5% molybdenum.Under both proportionings, the temperature-coefficient of electrical resistance of heat generating member 1 is about 1.1 × 10-3/℃。
In a word, above-mentioned a variety of mix proportion schemes or similar mix proportion scheme on heat generating member 1 are passed through so that when between 0 DEG C~350 DEG C, the temperature-coefficient of electrical resistance of heat generating member 1 is 0.3 × 10-3/ DEG C~3 × 10-3/ DEG C so that in heat generating member 1 during temperature rises, significant change can occur for the heating resistor of heat generating member 1.
Further, in specific implementation process, the heat generating member 1 obtained is matched by above-mentioned material has good heat resistance, plasticity, weldability and toughness etc., and heat generating member 1 can be thread or sheet.Wherein, when heat generating member 1 is thread, set its a diameter of 0.08mm~0.4mm, because the toughness and hardness of heat generating member 1 in this programme are better than traditional nichrome and Aludirome, when assembling thread heat generating member 1, be not in the situation of heating wire crimp, preferably ensure that the normal work of heat generating member 1.In addition, it refer to Fig. 2 a and Fig. 2 b, Fig. 2 a are a kind of concrete structure diagram of thread heat generating member 1, heat generating member 1 is the device for being provided with helical form atomization portion, the end of the atomization portion is provided with two connection ends being connected with power supply module (11,12), in conjunction with Fig. 2 b, and the atomization portion is used to contact tobacco tar adsorption piece 13 (the oil suction cotton-padded covering being for example wound into by cotton material), so that tobacco tar adsorption piece 13 adsorbs tobacco tar, and atomization tobacco tar is carried out during 1 operational heat of heat generating member.
In specific implementation process, the original supply voltage of power supply device (such as battery) in power supply circuit 2 is smaller (such as 4.2V), in order to after detecting user's smoking and battery be electrically connected with heat generating member 1, rapidly heat generating member 1 can be heated, so that the temperature water that the temperature of heat generating member 1 is rapidly risen to needed for atomization tobacco tar
It is flat, usually require to set the booster circuit being connected with power supply circuit 2 in electronic cigarette, it is therefore an objective to which the primary voltage that battery is exported is boosted, in the case where battery output electric energy and load are certain, to increase power output, and then quick heating heat generating member 1；In this process, in order to increase atomization amount of smoke to improve the usage experience of user, booster circuit can export as far as possible big power to heat generating member 1 in existing electronic cigarette, but if blindly increase heating power can cause the temperature of heat generating member 1 too high again, ultimately result in the bad consequence that electronic cigarette burns.To this, the present embodiment provides a kind of specific voltage-regulating circuit 3, can be that heat generating member 1 provides heating power as big as possible on the premise of not causing to burn cotton (i.e. the heating temp of heat generating member 1 is maintained in preset temperature range) during boosting.
