Embodiment
As shown in Figure 3, a kind of gas-cooker backfire control device, includes the vent line of gas-cooker, and vent line is main to be supplied
Tracheae 21, it connects outer source of the gas.The main connected component air supply pipe of air supply pipe 21, branch air supply pipe connection burner 11.Branch air supply pipe is connected
Ignition switch 12, ignition switch 12 connects two gas-cooker air supply pipes 22, and a gas-cooker air supply pipe 22 connects outer mixing chamber 23,
Another gas-cooker air supply pipe 22 connects interior mixing chamber 24, and two mixing chambers all connect burner 11.Burner 11 is provided with point
Fiery pin 31 and thermocouple 32（Also it is blowout protection pin）, the connection ignition switch 12 of ignition electrode 31, ignition switch 12 is interior to be provided with electromagnetism
Valve 34, the electric-connection thermal galvanic couple 32 of magnetic valve 34.
Such as Fig. 3,4, outer mixing chamber 23, interior mixing chamber 24 are designed with air inlet 5（Also it is air register）, mixing chamber passes through combustion gas
Stove air supply pipe 22 supplies combustion gas, and from there is air inlet 5 to supply air, burner 11 is conveyed to after its internal mix.Research discovery,
During tempering, flame is burnt at air inlet 5.
So, this gas-cooker backfire control device fixed temperature relay 4, the temp probe 41 of temperature relay 4 is located at
In the top of air inlet 5.Circuit communication between temperature relay 4 and magnetic valve 34, thermocouple 32, and temperature relay 4 controls
Make the closure of the circuit, disconnect, temperature relay 4 is closed type.
