Embodiment：Governor circuit figure (see Fig. 3).

Now circuit structure is described below：

Be delayed break contactWith stop button T, the normally-closed contact exported by subsidiary engine 2 (via plug Socket C1 networks), start button Q, relay J, series winding access civil power both ends successively, and J-1 contacts and be connected in start button Q's Both ends；The contact of J-2, J-3, J-4 tri- and company, and be serially connected with live wire, then contacted again with K1；Four of power outlet 20 insert Hole _ _ is connected to the civil power both ends after K1 successively, and the mechanical, electrical magnet valve 15 of fuel feeding cigarette, electromagnetic oven use respectively, and the 4th jack is standby； Behind S1 both ends and DT 1-0 ends series winding, the mains supply after K1, and DT-D indicator lamps and the both ends for being connected in S1 are connected to；DT 2 ends be connected with S3 one end, S3 another line of termination civil power 0；Contact S1-1 one end is closed in delay, connects the line of civil power 0, another Terminate S2 one end and K2 common port 0；One end of S2 another termination audible-visual annunciator 18, and be connected with the live wire after K1； K2 10 line of termination, K2 2 ends are connected with the other end of audible-visual annunciator 18.

Now operation principle is described below：

A, in abnormal cases, i.e., when gas concentration is exceeded, the automatic sound-light alarm-of subsidiary engine 2 and meanwhile its it is normally closed output touch Point (being networked via plugs and sockets C1) disconnects, and causes networking to fail, therefore relay J dead electricity, then appliance circuit whole power-off _ electromagnetism The dead electricity of valve 15 is closed, so as to cut off source of the gas；Simultaneously its another group of normally opened contact (being networked via plugs and sockets C2) but closure _ so as to Trigger special voice IC6 audio alerts _ prompting user correctly to dispose, until dangerous situation excludes, alarm stops, and now instrument is automatically extensive Normal condition is arrived again.

B, in normal state, instrument should use according to the following steps：

Instrument power plug is inserted into power outlet first, K1 is also preliminarily placed in the position of " logical ", and the gas circuit of gas-cooker is pressed Figure connects, by by-passing valveClose, then in the case where being not powered on, because magnetic valve 15 (normally closed) is off state, therefore gas circuit It is obstructed.Now：

First, start button Q, J-1 self-insurance adhesive is pressed, then relay J is obtained electric, the equal adhesive of J-2, J-3 and J-4, therefore electric Road is powered, and lampblack absorber obtains electric work, and magnetic valve 15, which is powered, to be opened, and is now opened gas stove switch and be can be used, flowmeter 10 is aobvious Show gas flow, micro differential pressure switch contact K2 actions, connect 0-2, be i.e. audible-visual annunciator 18 and S2 is simultaneously even stand-by；Other electromagnetism Stove is also powered stand-by.

2nd, S1 is used for circular flow in short-term (such as steamed bun), such as is arranged to 10 minutes (The times _ can be according to personal habits And concrete condition, arbitrarily set)；S2 is used for sound and light alarm, is arranged to 1.5 minutes；Timing (time _ can root when S3 is used for long According to personal habits and concrete condition, arbitrarily set) operation (such as Tun meat, stewing rice), such as be arranged to 30 minutes, it is applicable respectively In different situations, selected for user.

3rd, after pressing start button Q, DT buttons are pressed, make DT_D lamps bright, i.e., indication circuit enters circular flow shape in short-term State, S1 i.e. with other electrical equipment it is electric, timing 10 assign to after, delay close contact S1-1 act, S2 obtain electric then sound and light alarm _ Remind housewife's processing：Such as _ such as still need to recycling work in 10 minutes, then DT is pressed, DT_D lamps go out, and sound and light alarm stops, then presses Once DT reset, DT-D lamps are bright, then S1 again it is electric _ work on, until again run 10 minutes after, S1-1 is closed again On, then second of sound and light alarm ... repeats above step as that need to continue cycling through.

If the 4th, after sound and light alarm, user is in 1.5 minutes of setting, non-timely processing _ be then delayed break contactIt will act, then relay J dead electricity, J-1 to J-4 break entirely, circuit dead electricity, and all electrical equipment power off, therefore magnetic valve 15 Also automatically shutting down gas circuit _ flame-out ensures safety.

Timing operation mode of operation when the 5th, such as using long, operation are as follows：

1st, by start button Q, then be powered work；

2nd, DT is pressed, DT-D lamps is gone out, now DT 0_2 is connected, (and 0_1 breaks, S1 dead electricity, then the first pattern is automatic Stop.) after then S3 obtains electric _ continuous firing 30 minutes, be delayed break contactDisconnect, then relay J dead electricity, Suo You electricity Device powers off, died.

6th, the conversion of above two operational mode-very is simple, in the process of running, presses multifunctional button DT, DT-D lamps are bright, as the operational mode of tape loop alarm in short-term；DT-D lamps go out, timing operation pattern when as long.

7th, the design also has advantage _ electric-linked：Stop button T is pressed, then powers off, die；Conversely, shut-off stove Switch _ on tool and forgotten also worry by stop button T (some careless housewives are often such ...), now due to minute-pressure The 0_1 that difference switch contact K2 acted _ made K2 is connected, and causes S2 to obtain electric effect, after 1.5 minutes _ delay break contactIt will act, and cause relay J1 dead electricity _ _ also to automatically power off, both saved the energy, and be advantageous to extend magnetic valve 15 again Service life.

8th, just because of two kinds of operational modes _ _ of the design be respectively provided with automatically power off, function of dying, so even if at home _ _ also can reliably automatically power off, die under nobody extreme case, can effectively avoid the generation of the major accidents such as fire, it is ensured that Safety.

9th, under power-off condition, not influence gas furnace use, by-passing valve 16 can be opened and supplied, when having electricity, then will bypass Valve is closed.
