A mechanical sensor and a control circuit are used for opening or closing an electromagnetic valve in a gas path. The utility model is mainly characterized in that an operating coil and a maintaining coil of the electromagnetic valve are connected with the output terminal of the control circuit, and the output of mechanical sensor is connected with the input terminal of the circuit. The utility model has the advantages of simply structure, reliable and safe operation, and gas saving.
Description
The utility model is a kind of gas kitchen ranges safe energy saving device in the gas kitchen ranges manufacturing technology field.
At present, gas kitchen ranges is in use wasted combustion gas and is one and general is problem that people were concerned about again, can not control big fire burning things which may cause a fire disaster pass automatically, open the defect of the waste combustion gas that is caused in order to overcome family expenses or public gas kitchen ranges, there has been the structure of pair gas kitchen ranges to correct, as adopt mechanical driving device to control lighting automatically of big fire burning things which may cause a fire disaster or extinguish, reach the purpose of saving combustion gas.But the structure of this device is more numerous and diverse, driving parts, the contact switch of particularly controlling magnetic valve damages easily, less reliable some, electrical equipment control is with city power supply safety inadequately.
The purpose of this utility model and task are the gas kitchen ranges safe energy saving devices of lighting automatically or extinguishing of the control gas kitchen ranges big fire burning things which may cause a fire disaster that sensor combines with control circuit of designing a mechanism, reach save combustion gas and kitchen range safe in utilization in the adverse circumstances of high temperature, high humidity and greasy dirt.
The technical solution of the utility model is conceived substantially with a mechanical pick-up device and is connected with control circuit, the moving valve circle L of suction of magnetic valve in the output control gas circuit of circuit
