[0024] The other end of the connecting pipe 12 is inserted into one side of the sealing end 15, the stopper 17 is provided with a ventilation hole at both ends, and the position of the small flow hole 16 is the same as the axial center of the ventilation hole on the stopper 17.

[0025] ​One end of the air guide pipe 9 is fixedly connected with the bottom of the fire row 4, one end of the air inlet pipe 13 is communicated with the gas, and the communication pipe 14 communicates the plurality of sealing ends 15 and the air guide pipe 9.

[0026] The air guide pipe 9 is provided with a moving port 26 at the position close to the bottom end of the guide plate 25, and the adjusting rod 27 is fixedly connected with the inside of the moving port 26 at one side of the adjusting roller 10, and the adjusting rod 27 is rotationally connected with the bottom end of the guide plate 25.

[0027] In the embodiment, the gas in the inside of the air inlet pipe 13 enters the connecting pipe 12 through the mechanical valve 2, enters the inside of the air guide pipe 9 through the sealing end 15, and is gathered between the sealing end 15 and the stopper 17 due to the blockage of the stopper 17. Since the air hole on the stopper 17 and the small flow hole 16 have the same position axis, and the diameter of the small flow hole 16 is small, the flow of the gas through the small flow hole 16 is small. After the gas passes through the small flow hole 16, the gas in the air guide pipe 9 is conducted to the inside of the cavity 8 through the air guide pipe 9, and enters the combustion base 20 through the cavity 8 and the fuel pipe 23, and finally the gas is emitted through the combustion base 20. The electronic ignition mechanism is arranged at the top of the shell 1, and the gas at the top of the combustion base 20 is ignited through the electronic ignition mechanism. Since the gas is small, the flame is small before use, and the combustion is maintained, which saves the gas.

[0028] Further, when the cookware is placed on the top of the shell 1, the bottom of the cookware will press the top of the sliding rod 5 due to the different sizes of the cookware, so that the sliding rod 5 slides in the inside of the shell 1, thereby pressing the sliding block 6 and the spring 7. The sliding block 6 slides downward to drive the linkage rod 24 and the guide plate 25 to press the adjusting rod 27 downward, so that the adjusting roller 10 rotates in the inside of the stopper 17, and the large flow hole 11 is switched with the small flow hole 16. The position of the large flow hole 11 is switched from deviating from the air hole on the stopper 17 to being the same as the axis of the air hole on the stopper 17, so that the air hole is communicated with the large flow hole 11. The diameter of the large flow hole 11 is much larger than that of the small flow hole 16, so that the flow of the gas through the large flow hole 11 is increased, the speed of the gas emitted from the top of the combustion base 20 is increased, the flame at the top of the combustion base 20 is increased, and the bottom of the cookware is continuously heated. According to the size of the cookware, the sliding rod 5 which is not pressed by the cookware has a small flame at the top of the fire row 4, which reduces the waste of fuel and saves the gas according to the size of the cookware.

[0029] Referring to Figure 1 , Figure 3 and Figure 4 , in a preferred embodiment, a plurality of air inlets 3 are arranged at two sides of the shell 1, and an air tank 18 is fixedly connected in the inside of the shell 1, and the inside of the air tank 18 is communicated with the air inlets 3.

[0030] The top of the fire row 4 is fixedly connected with a heat preservation plate 22, and the top edge of the heat preservation plate 22 is fixedly connected with a plurality of support rods 21, which serve to increase the distance between the cookware and the top of the heat preservation plate 22.

[0031] The side of the heat preservation plate 22 close to the edge of the top of the shell 1 is fixedly connected with a plurality of air pipes 19, and the bottom end of the air pipe 19 is inserted into the inside of the air box 18.

[0032] In this embodiment, when cooking, the flame temperature at the bottom of the cookware heats the surrounding air, the hot air rises, the heat preservation plate 22 reduces the contact between the flame and the air, which has the effect of maintaining the temperature at the top of the combustion base 20, and the plurality of support rods 21 keep the combustion base 20 away from the bottom of the cookware, so that fresh air enters the inside of the air pipe 19 through the air inlet 3 and the air box 18, mixes with the gas through the air pipe 19, and burns, which has the effect of providing oxygen for the gas combustion.

[0033] Working principle: when in use, the gas in the intake pipe 13 passes through the mechanical valve 2 into the connecting pipe 12, and then into the gas guide pipe 9 through the sealing end 15. Due to the blockage of the stopper 17, the gas gathered between the sealing end 15 and the stopper 17. Since the air hole on the stopper 17 and the small flow hole 16 have the same axis, and the diameter of the small flow hole 16 is small, the flow of gas through the small flow hole 16 is small. After the gas passes through the small flow hole 16, it enters the cavity 8 through the conduction of the gas guide pipe 9, and then enters the combustion base 20 through the cavity 8 and the fuel pipe 23. Finally, the gas is emitted through the combustion base 20. An electronic ignition mechanism is arranged on the top of the shell 1. The gas on the top of the combustion base 20 is ignited by the electronic ignition mechanism. Since the gas is small, the flame is small before use, and the combustion can be maintained, which saves gas. When the cooker is placed on the top of the shell 1, the size of the cooker is different, and the bottom of the cooker will press the top of the sliding rod 5, so that the sliding rod 5 slides in the shell 1, thereby pressing the sliding block 6 and the spring 7. The sliding block 6 slides downward to drive the linkage rod 24 and the guide plate 25 to press the adjusting rod 27 downward, so that the adjusting roller 10 rotates in the stopper 17, and the large flow hole 11 is switched with the small flow hole 16. The position of the large flow hole 11 deviates from the air hole on the stopper 17, and then rotates to the same axis of the large flow hole 11 and the air hole on the stopper 17, so that the air hole and the large flow hole 11 are communicated. The diameter of the large flow hole 11 is much larger than that of the small flow hole 16, so that the flow of gas through the large flow hole 11 is increased, the speed of the gas emitted from the top of the combustion base 20 is increased, the flame on the top of the combustion base 20 is increased, and the bottom of the cooker is continuously heated. According to the size of the cooker, the sliding rod 5 that is not pressed by the cooker has a small flame on the top of the fire grate 4, which reduces the waste of fuel and saves gas according to the size of the cooker. When cooking, the flame temperature at the bottom of the cooker heats the surrounding air, the hot air rises, and the heat plate 22 reduces the contact between the flame and the air, thereby maintaining the temperature of the top of the combustion base 20. By arranging a plurality of supporting rods 21, the combustion base 20 is kept away from the bottom of the cooker, so that fresh air enters the air pipe 19 through the air inlet 3 and the air tank 18, mixes with the gas in the air pipe 19, and burns, thereby providing oxygen for the gas combustion.

[0034] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. The replacement can be a partial structure, device, method step replacement, or a complete technical solution. According to the technical solution and the utility model concept of the present application, equivalent replacement or change should be covered within the protection scope of the present application.
