The specific embodiment

As shown in Figure 1, a kind of intelligent-induction cigar lighter comprises power circuit 1, and this circuit is that civil power provides after step-down, rectification, voltage stabilizing+the 5V working power; It is characterized in that: it is provided with microprocessor control circuit 2, photoelectric sensor circuit 3, touch induction circuit 4, the circuit 5 that lights a cigarette, delay circuit 6, overtemperature alarm circuit 7, wherein the input port of the microprocessor chip IC2 of microprocessor control circuit 2 connects the time K switch 1～K7 is set, delivery outlet J is connected through the base stage of resistance R 6 with switching tube VT2, and switching tube VT2 and relay J 1 are serially connected in both ends of power; Photoelectric sensor circuit 3 is formed transceiver circuit by transmitting tube VD11, receiving tube VD12, the work of the output signal of receiving tube VD12 control auxiliary reclay J2 after triode VT3, VT4 amplify, and the normally opened contact of J2 is controlled the work of the circuit that lights a cigarette; The signal output pin of the touch sensible sheet TP1 of touch induction circuit 4 and the input pin of control chip IC4 join, the work of the output pin control auxiliary reclay J4 of IC4, the work of the normally opened contact control auxiliary reclay J2 of J4; The supply pin of the control chip IC3 of delay circuit 6 is by the normally opened contact control of auxiliary reclay J2, and the output pin of IC3 is controlled the work of auxiliary reclay J5; The temperature detect switch (TDS) ST control auxiliary reclay J3 work of overtemperature alarm circuit 7, J3 contact control Music Clip IC6 work.The detailed operation principle of circuit is such: power supply is given the T1 transformer-supplied through the plug-type earth leakage protective device; form step-down rectifier, filtering, voltage stabilizing through VD, VIM, C1, C2, ICI, C3, C4 etc.; provide 5 reliable and stable couchers to make voltage R1, VD5 to complete machine and form the indication that powers on; form current limliting voltage stabilizing, filtering through R2, VD6, VD7, VD8, C5 again, the operating voltage of 1.5V is provided for eight little processing time control chip LD 1 of IC2.The PV end is the detection of power loss end, the highest mouthful of line voltage is lower than the supply voltage of chip, externally during power down when 5V power supply (in the schematic diagram no), the PV port is low level, chip will be closed the driving output of J port automatically, thereby reduce the energy consumption of battery (for chip power supply), prolong battery service time.When regularly being set when arriving the opening time, by IC2, J port output high level triggers VT2 conducting J1 through R6 and gets electricly, and contact 1 adhesive provides 5V voltage to inductive control circuit, and VD10 regularly enables indicator lamp.When cigarette set-point mouth, block the signal of telecommunication that VD11 sends, VD12 carried and ended this moment, and VT3 ends, and triggers VT4 by R10 through R11, and J2 gets electric, and contact 1 and contact 2 adhesives are simultaneously powered to IC3.2 adhesives of J2 contact, through the R25 current limliting, by IC5,6,4 pin trigger the VS1 conducting through J3, J5, R23 conducting IC5,220V civil power.Through the VD18 rectification, R26 current limliting C10 discharges and recharges, and D1 conducting VD15 sends strobe light, and prompting heating wire this moment is in heating.Pass through the filtering of VD16-VD19 full-bridge rectification again, switch change-over, small size magnetic core insulate step-down transformer, three parts are formed.Through the triple diffusing surface glassivation of alteration switch NPN type planar ransistor, VT8, VT9 give T3, make secondary coil obtain 12V/50W voltage again, give the heating wire power supply that lights a cigarette, and cigarette is lighted rapidly.After IC3 powers on, form the limit delay circuit through RP1, R15, R16, C6,5 pin are made end of voltage ratio, through RP1.R16。After the time of C6, trigger interior overturn set, 3 pin output Gao Ping, J5 gets electric, and the contact disconnects, and end lights a cigarette.TP1 is the touch sensible sheet, when staff touch sensible sheet, because the induction effect of human body, there is signal to enter 2 pin of IC4, so IC4 triggers set by TP, the 3 pin output high level of IC4, J4 gets electric, contact J4/1 adhesive, and J2 gets electric back conducting J2/1, form photoelectricity through J3, J5, R24, IC5, R25 and isolate triggering VS1 conducting electrical isolation transformer, power to heating wire.This touch function is for easily focus cigarette is provided under the varying environment temperature fast.Because IC4 is operated in monostability, after hand leaves metal touch sheet, through RP3.C8 is after the time, overturns again and reset in time base circuit inside, and IC4,3 pin return to electronegative potential again.When frequency of utilization was too high, ST was the directly-heated type temperature detect switch (TDS), and switch motion is 180 ℃, because of ST is mounted on the heat radiation aluminium flake, with heating wire certain distance is arranged, when frequency of utilization was high, the temperature of heating wire passed to ST through the heat radiation aluminium flake gradually, the contact is disconnected, this moment, VT5 ended, and triggered VT6 by R13 through R14, and J3 gets, disconnect the power supply that leads to IC5, make the outage of electrical isolation transformer.In addition, 2 adhesives of J3 normally opened contact, the IC6 musical film gets electric, the luminous prompting of VD17, this moment, BL1 sent interesting to listen to music, pointed out at this moment overtemperature.This product is fit to public occasion, use the smoking seat, has easy to use, health, safe and reliable advantage.
