Be used to judge whether to connect with the mains back button input for the first time to select to connect the selected cell of password generation unit or comparing unit; The function of selected cell is: if judged result is cryptographic key input for the first time behind the last power supply, the input of cryptographic key is communicated with the password generation unit so, if judged result is not cryptographic key input for the first time behind the last power supply, the input of cryptographic key is communicated with the password comparing unit so;
Optionally with described selected cell conducting to generate lighter and open password and with the password generation unit of the password feed-in password comparing unit that generated, described password generation unit will be gone up the unlatching password of the numerical value of the button input first time behind the power supply as lighter; Cryptographic key 8 has three: cryptographic key A, cryptographic key B be the combinatorial input password arbitrarily, cryptographic key C is an acknowledgement key, behind the password of after loading onto battery, setting by the own desire of any combinatorial input of cryptographic key A, B for the first time, press acknowledgement key C affirmation again after, single-chip microcomputer 12 promptly can be remembered this password automatically.
Optionally with the selected cell conducting, open the consistent password comparing unit that is condition to executing agency's output arming sequence of password with input code and lighter; The igniter (lighter) that accesses to your password earlier will be by the previous password of setting of cryptographic key A, B input, after press acknowledgement key C and confirming, when selected cell is judged on not being behind the power supply button input for the first time, the password and the unlatching password of button input is compared; As (for example: high level signal) conform to then single-chip microcomputer 12 outputs to safety and arming device output arming sequence;
Open cryptographic core to after consistent at input code and lighter, the delay unit of the effective time of default arming state picks up counting, and lighter is in the arming state, is 10 seconds as setting effective time, executing agency's action in 10 seconds effective time, lighter can be lighted a fire;
The reference edge of password comparing unit is connected with the output of password generation unit, the output of password comparing unit is connected with executing agency, executing agency cooperates with the sparking assembly, delay unit is connected with the output change-over switch of password comparing unit, be that delay unit is used to control the time that comparing unit output high level state is kept, the state of the change-over switch of the output of comparing unit is judged whether to surpass the judged result decision of effective time by delay unit, when the password comparing unit is output as high level, delayer timing this moment and executing agency's action, lighter is in the arming state and exceeds default effective time up to the delay unit timing, delayer zero clearing this moment, the output change-over switch of comparing unit action simultaneously, the output of single-chip microcomputer changes into low level by high level, and safety position recovers in executing agency.
The executing agency that shows among Fig. 7 is an automatically controlled travel switch 9, described automatically controlled travel switch 9 cooperates with button ignition switch 3 and is installed in the casing 1 of button ignition switch lower end, when correct input of password and affirmation, above-mentioned single-chip microcomputer 12 output high level, allow automatically controlled travel switch 9 switch on, the bolt indentation on the automatically controlled travel switch 9, the button ignition switch 3 of lighter just can be pressed, press hand otherwise the bolt of automatically controlled travel switch can block, can't light a fire.Both safety continues automatic disconnection again after 10 seconds, so can guarantee the time enough igniting again.
The executing agency that shows among Fig. 8 is the magnetic valve 10 that is contained in vapour case exit, magnetic valve 10 is by 12 controls of this single-chip microcomputer, only just export high level signal (and continuing 10 seconds) and give magnetic valve 10 at the input proper password and after confirming, can open the gas outlet in the vapour case 5 after magnetic valve 10 energisings, fuel output is closed after 10 seconds automatically.
The course of work of remainder and embodiment 1 are identical.
Executing agency is an one stroke switch 11 among Fig. 9, and described travel switch 11 cooperates with the skull 2 of lighter, and travel switch 11 is installed in the casing 1 of skull inboard.Load onto travel switch at skull 2 and shell 1 joint, this switch is controlled by this enciphered ignition device, after the correct input of password and confirming, and enciphered ignition device output high level signal, the bolt on the switch is withdrawn, and then skull can be opened, otherwise pins skull, can't open.Delay procedure in the single-chip microcomputer is limited to 10 seconds in the time of can guaranteeing high level lasting, closes the output of single-chip microcomputer after 10 seconds automatically, and skull can not be opened.
The course of work of remainder and embodiment 1 are identical.
