[0079] one, it is directed to the above-mentioned the scheme for 1) planting short-circuit heating wire 101 in situation, at least there is following two specific embodiment:
[0080] (1) referring to FIG. 4, discharge circuit 40 include: the first operational amplifier 401 and with the first operational amplifier 4
01 connected first resistor 402;
Two input terminals (i.e. negative, positive input terminal) of [0081] first operational amplifier 401 are connected with the positive and negative anodes (IN+/IN-) of the first battery 201 respectively, and the output end of the first operational amplifier 401 is connected by first resistor 402 with the anode of the second battery 30；The cathode of second battery 30 is connected with the cathode of the first battery 201；In addition, in the specific implementation process, the series resistor R1 between 201 anode of the first battery and 401 negative input end of the first operational amplifier can be needed according to circuit design (depending on resistance value is according to concrete condition)；
[0082] when the first battery 201 is electrically connected inch with the first operational amplifier 401, the second battery 30 is discharged by first resistor 402；By adjusting the resistance value of first resistor 402, the electric discharge inch for adjusting discharge circuit 40 is long, so that first inch is long long equal to second inch.
[0083] further, with continued reference to FIG. 4, protection circuit 50 includes: that second operational amplifier 501 and the first Jian close part
502；
[0084] input terminal of second operational amplifier 501 is connected with the first battery 201, and another input terminal is connected with the second battery 30, and output end closes part 502 with the first Jian and is connected；It is in parallel with heating wire 101 that first Jian closes part 502.Specifically, as shown in Figure 4, the negative input end of second operational amplifier 501 is connected on the positive and negative anodes of the first battery 201 by the bleeder circuit that resistance R2, R3 are constituted, positive input terminal is connected with the anode of the second battery 30, generating positive and negative voltage end (V+/V-) is connect with the positive and negative anodes of the first battery 201 respectively, and output end connects the anode of the first battery 201 by resistance R4；It is P-channel enhancement type FET that first Jian, which closes part 502, the grid (G1) that first Jian closes part 502 is connected with the output end of second operational amplifier 501, and the first Jian closes the source of part 502, drain electrode (Sl, D1) is connected with the positive and negative electrode of the first battery 201 respectively；The both ends of heating wire 101 are equally connected with the positive and negative anodes of the first battery 201 respectively, i.e. the first Jian closes part 502 and heating wire 101 is connected in parallel on the both ends of the first battery 201.
[0085] when the voltage of the second battery 30 is less than or equal to the preset value inch, it is in the conductive state that second operational amplifier 501 controls the pass the first Jian part 502, so that 101 short circuit of heating wire, and then the first battery 201 is made to stop powering to heating wire 101.
[0086] concrete operating principle of circuit shown in Fig. 4 are as follows: on the one hand, when electronic cigarette 100 detects that smoking acts inch, electricityTo the power supply of atomizer 10, (i.e. controller 60 controls the first battery 201 and powers pond bar 20 to atomizer 10, it is not drawn into Fig. 4), it powers with the first battery of inch 201 to the first operational amplifier 401, first battery, 201 voltage adds to the negative input end of the first operational amplifier 401 through resistance R1, the input terminal of first operational amplifier 401 exports low level, so as to form pressure difference between the second battery 30 and the input terminal of the first operational amplifier 401, and it is discharged by first resistor 402, between electric discharge inch by adjusting adjustable second battery 30 of resistance value of first resistor 402, so that it is atomized between inch unanimously with tobacco tar.On the other hand, when electronic cigarette 100 detects that user stops smoking inch, to the power supply of atomizer 10, (i.e. controller 60 controls the first battery 201 and stops powering the stopping of battery rod 20 to atomizer 10, it is not shown in Fig. 4), first operational amplifier 401 stops working, its output end stops output low level, and the second battery 30 stops electric discharge.During battery rod 20 is that atomizer 10 is powered, when more (i.e. 30 electricity of the second battery the is sufficient) inch of tobacco tar residue, the positive input terminal voltage of second operational amplifier 501 is higher than negative input end voltage, exports high level from the output end of second operational amplifier 501；Since the conducting of field-effect tube is controlled with cut-off by gate source voltage, for P-channel enhancement type FET, gate source voltage is the forward voltage then disconnected Jian of pipe, so, when the output end of second operational amplifier 501 exports high level inch, 1 voltage of grid G is higher than 1 voltage of source S (i.e. gate source voltage is forward voltage), and the first Jian closes part 502 (i.e. P-channel enhancement type FET) disconnected Jian, and the first battery 201 is continuously the power supply of heating wire 101；When tobacco tar will exhaust (i.e. critical to exhaust) inch, the electricity of second battery 30 will also discharge, if this inch detects user's smoking and detects 30 voltage of the second battery lower than the setting value, then the positive input terminal voltage of second operational amplifier 501 is lower than negative input end voltage, exports low level from the output end of second operational amplifier 501；For P-channel enhancement type FET; gate source voltage is that then pipe is connected backward voltage; so; when the output end of second operational amplifier 501 exports low level inch; 1 voltage of source S is higher than the voltage of grid G 1 (i.e. gate source voltage is backward voltage); first Jian closes part 502 (i.e. P-channel enhancement type FET) conducting; heating wire 101 is short-circuited; main control module in this inch battery rod 20 detects 101 short circuit of heating wire; then enter short-circuit protection state, the first battery 201 not output voltage.Wherein, controller 60 may include closing with the concatenated transistor Jian of the first battery 201 and for controlling the on-off that the transistor Jian is closed to control the single-chip microcontroller of the first battery 201 electric discharge.It is understood, therefore, that the circuit structure of controller 60 is not specifically limited herein.
