Background technology
Along with the such as electric heating appliance such as electric cooking pot, warmer widespread use, the family fire caused by electric heating appliance fault and the hidden danger of safety in production also increasing.This is because electric heating appliance may make the thermoplastic of inside and outside or timber produce smog and naked light at work.Traditional security protection measure settles smoke alarm in a room, but this mode can only process by reminding user, cannot initiatively take measures, and controls burning things which may cause a fire disaster.Make it no longer produce heat if can cut off the electricity supply when electric heating appliance heating is smoldered, just effectively can reduce the possibility that fire occurs.
Chinese patent CN200810037244.1, September 24 2008 day for announcing, announce a kind of warning system based on smog alarm, comprise smoke alarm body, and for being arranged on the host main body near smoke alarm body, it also comprises: whether the smokescope for detecting according to smoke alarm body exceeds standard and send the wireless launcher of corresponding alarm signal, host main body inside is provided with the wireless receiver receiving alarm signal, being provided with what receive that wireless launcher sends when wireless receiver is that the defence area that the alarm signal in warning defence area starts corresponding warning defence area starts module for starting described smoke alarm body region, for after defence area startup module has started the warning defence area at smoke alarm body place, and wireless receiver sends alarm enabling signal alarm after receiving the alarm signal of wireless launcher transmission starts module, and the gsm module of corresponding alarm is sent for starting the alarm enabling signal that sends of module and respective objects communicator according to alarm, so can realize setting warning defence area as required.This type of prior art does not say complex structure, but this type of technology cannot realize after smog appears in any room, at once by all consuming device power-off, controls the object that potential fire origin generates heat further.
Utility model content
The utility model object is that solving prior art cannot realize after smog appears in any room, at once by all consuming device power-off, control the problem that potential fire origin generates heat further, after providing a kind of any room to occur smog, at once by all consuming device power-off, control the heavy current box of the smoke sensing power-off that potential fire origin generates heat further.
The utility model solves the technical scheme that its technical matters adopts: a kind of heavy current box of smoke sensing power-off, comprise casing, casing connects L inlet wire, N inlet wire and PE inlet wire, several air switches and break alarm circuit is provided with in described casing, be connected with L inlet wire by isolating switchs of several series connection after the inlet wire of described air switch is interconnected on inlet wire tie point, the outlet of described air switch is connected with socket respectively, the all corresponding smog probe of each isolating switch, each smog probe all connects with corresponding isolating switch, described inlet wire tie point is connected with the L line link of break alarm circuit, the N line link of break alarm circuit is connected with N inlet wire, described break alarm circuit comprises AC/DC change-over circuit, relay K 1, electric capacity C1, resistance R1 and electric bell, the L line input end of described AC/DC change-over circuit is connected with inlet wire tie point, the N line input end of described AC/DC change-over circuit is connected with N inlet wire, the L line output terminal of described AC/DC change-over circuit is connected with the first end of relay K 1, second end of relay K 1 is connected with the N line output terminal of AC/DC change-over circuit with electric bell by the normally closed contact of relay K 1 successively, second end of relay K 1 is also connected with the N line output terminal of AC/DC change-over circuit with resistance R1 by electric capacity C1 successively.The live wire end of incoming cables of heavy current box is in series with one or more isolating switch, and these isolating switchs are subject to the control of smoke sensing probe, and smoke sensing probe is placed in the roof of not chummery.When there being smog to produce in room, smoke sensing probe meeting trigger alarm loudspeaker and coupled isolating switch simultaneously, the live wire of heavy current box disconnects by this isolating switch.Because all isolating switchs are all connected on live wire end of incoming cables, therefore any one room detects that smog all can cut off general supply.The utility model interrupt line warning circuit normally closed contact that do not work at ordinary times is in open mode, when isolating switch works, relay K 1 must not be electric, normally closed contact is in closure state, electric capacity C1 discharges, also quit work after of short duration electric discharge is reported to the police, both played the effect of warning, prevented again the fire that further electricity consumption causes.
As preferably, break alarm circuit also comprises diode D1, the anode of described diode D1 is electrically connected with the second end of relay K 1, and the negative electrode of described diode D1 is connected with described electric capacity C1, and the negative electrode of described diode D1 is also connected with the normally closed contact of described relay K 1.Such setting, serves anti-reverse effect.
As preferably, break alarm circuit also comprises the normally opened contact of relay K 1, the normally opened contact moving contact of described relay K 1 is electrically connected with the second end of relay K 1, the normally opened contact stationary contact of described relay K 1 is connected with described electric capacity C1, and the normally opened contact stationary contact of relay K 1 is also connected with the normally closed contact of described relay K 1.Arrange like this and serve anti-reverse effect equally.
Substantial effect of the present utility model is: after smog appears in any room, at once by all consuming device power-off, control potential fire origin to generate heat further, the utility model interrupt line warning circuit normally closed contact that do not work at ordinary times is in open mode, when isolating switch works, relay K 1 must not be electric, normally closed contact is in closure state, and electric capacity C1 discharges, and also quits work after of short duration electric discharge is reported to the police, both play the effect of warning, prevent again the fire that further electricity consumption causes.
