The specific embodiment
As shown in Figure 1, 2: this combustion gas leakproof alarm set, it comprises casing (1), is installed in power supply (2), indicator lamp (3) and buzzer (4) in the casing, contact device A and contact device B, power supply, indicator lamp and buzzer are connected by lead successively, power supply (2), buzzer (4) are connected with the contact device A of similar " contactor " by lead, and contact device A device is on fuel cartridge (5); Power supply (2), indicator lamp (3) are connected with the contact device B of similar " contactor " by lead, and contact device B is installed in the valve (13) of gas-cooker (12); The rated power of buzzer and indicator lamp differs less than 0.1 watt, and the resistance of buzzer is more than 20 times of indicator lamp resistance.
Described combustion gas leakproof alarm set, its contact device A is made up of fixed block (8) and contact ring (10), fixed block (8) is installed on the guard shield (7) of fuel cartridge, fixed block is provided with two sheet metals (9), power supply (2) is connected by a lead and a sheet metal are terminal, and buzzer (4) is connected by lead and another sheet metal are terminal; Contact ring (10) device is on air valve (6), and contact ring is provided with contact head (11); The Unscrew air valve, contact head extrusion metal sheet makes the two metal sheets contact, and buzzer is sounded a buzzer.
Described combustion gas leakproof alarm set, its contact device B is made up of circular gasket (14) and Metal Contact bar (15), pad the right and left is installed the wire (16) of first quarter moon shape, and Metal Contact bar (15) is arranged on pad (14) central authorities, be positioned at valve handle under; Power supply (2) one ends are connected with a wire by lead, and indicator lamp (3) one ends are connected with another wire by lead.
Described combustion gas leakproof alarm set, it can adopt several contact devices B, and device is in several valves of two kitchen ranges or many kitchen ranges.
Operation principle of the present utility model: the series connection of two electrical equipment, resistance difference is apart from huge, and rated power is more or less the same, then an electrical work and another electrical work is not obvious.
The switching of the air valve of fuel cartridge and the valve of gas-cooker, determine jointly the duty of buzzer and indicator lamp, the logical relation of the two be " or ".
The air valve of Unscrew fuel cartridge, drive the contact ring rotation on the air valve, contact head on the contact ring contacts with sheet metal, the extrusion metal sheet makes the two metal sheets contact, as shown in Figure 3, K switch 1 closure, power supply, indicator lamp, buzzer form the closed-loop path, and buzzer is sounded a buzzer, and indicator lamp does not work; The valve of Unscrew gas-cooker then, the Metal Contact bar that drives under the valve handle rotates, and contacts with the wire of two symmetries, as shown in Figure 3, K switch 2 closures, power supply, indicator lamp form the closed-loop path, buzzer is by short circuit, and buzzer is sounding not, and indicator lamp is bright; Close the valve of gas-cooker, the Metal Contact bar disconnects with wire and being connected, and K switch 2 disconnects, and buzzer is sounded a buzzer, and indicator lamp does not work; Close the air valve of fuel cartridge again, contact head on the contact ring and sheet metal disconnect, and two metal sheets does not contact, and K switch 1 disconnects, and buzzer is sounding not, and indicator lamp does not work, and the combustion gas in the fuel cartridge is not just leaked; If close the air valve of fuel cartridge earlier, the air valve of gas-cooker does not close, and promptly K switch 1 disconnects, K switch 2 closures, and then indicator lamp is bright, reminds the end user to close the air valve of gas-cooker, closes not sounding of back buzzer, and indicator lamp does not work.
Hence one can see that, and this combustion gas leakproof alarm set reminds people is all closed all valves finishing after meal, stops the possibility of gas leakage.
