As preferably, in order to increase the firmness of airway, the making material of described airway is PVC.
As preferably, when airway is clamped by fixed block and slip, increase the sealing of airway, in described airway
Also it is arranged with rubber tube.
The invention has the beneficial effects as follows, this has the gas-cooker deft design of automatic closing gas function, structure after fire extinguishing
Rationally, by the conducting rod on on-off control knob and bus against, connect power supply, make temperature sensor check at burner
Temperature, when the temperature checked is relatively low, PLC control motor rotate, close airway so that gas-cooker is air tight, protect
Hinder the safety of people.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only with
The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
As Figure 1-Figure 4, a kind of have the gas-cooker of automatic closing gas function after fire extinguishing, including main body 1 and arrange
Airway 4, burner 3, pan bracket 2, on-off control knob 5, PLC, aneroid battery and air shutter structure on the body 1;
Described airway 4 connects with burner 3, and described burner 3 is positioned at the top of main body 1, and described pan bracket 2 is positioned at combustion
The top of burner 3, described on-off control knob 5 controls the open and close of burner 3;
Described air shutter structure includes conducting rod 6, bus 7, spring 8, screw mandrel 9, temperature sensor 13, motor 12, fixes
Block 11 and slide block 10, described conducting rod 6 has two, and two conducting rods 6 are arranged at the homonymy of on-off control knob 5, described in lead
It is internal that electric pole 6 is positioned at main body 1, and described bus 7 is positioned at the side of conducting rod 6, and described bus 7 is vertically arranged, described conduction
The length of bar 7 is more than the diameter of on-off control knob 5, and two conducting rods 6 are arranged at the homonymy of bus 7, described conducting rod 6
And being provided with space between bus 7, described bus 7 is connected with main body 1 by spring 8, and described temperature sensor 13 is arranged on
On pan bracket 2, one end of described screw mandrel 9 is arranged on motor 12, and described motor 12 is fixed on fixed block 11, described fixed block
11 are arranged in main body 1, and described slide block 10 is provided with through hole, are provided with screw thread, the screw thread in described through hole and silk in described through hole
Bar 9 mates, and one end of described screw mandrel 9 is connected on the output shaft of motor 12, and described screw mandrel 9 is through fixed block 11 and through hole, institute
The other end stating screw mandrel 9 is positioned at the top of slide block 10, and described fixed block 11 and slide block 10 lay respectively at the both sides of airway 4, institute
State fixed block 11 and slide block 10 all with airway 4 against;
