The outer ring air outlet 114 is selectively communicated with the air inlet 112 through an air separation passage to form an outer ring air path.
When the gas stove needs to start ignition operation, the valve core 12 is controlled to rotate to an ignition gear, so that the gas inlet 112 is communicated with the inner ring gas outlet 113 through an ignition channel, only the inner ring gas channel is discharged at the moment, and other gas channels are closed, and referring to fig. 4-6, the valve body structure is provided with an independent ignition gear, and the ignition gear only provides the needed most proper gas supply amount for ignition so as to meet the stable ignition under different environmental conditions, thereby avoiding the problems of starting ignition under the condition of rated maximum load, easy deflagration, ignition failure and the like. After the ignition of the gas stove is successful, the valve core 12 is controlled to rotate to the maximum fire power gear, so that the air inlet 112 is respectively communicated with the inner ring air outlet 113 and the outer ring air outlet 114 through the air dividing channels, and all air paths are exhausted at the moment, and the gas stove is referenced to fig. 7-9.
In particular, the gas separation channel and the ignition channel may be independent of each other or may partially overlap.

The valve core 12 has oppositely disposed tapered and connecting segments. The ignition channel comprises an ignition hole 121 and a central air passage 120, wherein the central air passage 120 is arranged at the central position of the conical section of the valve core 12 and penetrates through one surface of the conical section, which is away from the connecting section, so that one end of the central air passage 120, which is away from the connecting section, is always communicated with the inner ring air outlet 113.

When the valve core 12 rotates to the air inlet 112 and is communicated with the central air passage 120 through the air inlet part, the valve body structure is in a fire gear beyond the ignition gear, and at the moment, the inner ring air passage is closed or the other air passages are closed.
Referring to fig. 4, the air intake portion includes a plurality of air intake holes 122, all of the air intake holes 122 are disposed on the outer side wall of the tapered section of the valve core 12 at intervals in the circumferential direction, and all of the air intake holes 122 are located on the same plane as the ignition hole 121.

The middle ring cavity of the burner 2 communicates with the middle ring air outlet 115 to achieve the desired gas for middle ring combustion of the burner 2.
When the air inlet 112 can be communicated with the middle ring air outlet 115 through the ignition channel, at this time, the inner ring air channel and the middle ring air channel of the ignition gear are both air-out, and the outer ring air channel is closed, as shown in fig. 4-6, the ignition is started under the condition of rated maximum load, the problem of easy deflagration is avoided, and after the ignition is successful, the middle ring fire can be ignited quickly, so that the ignition efficiency is improved. When the valve core 12 rotates to the maximum fire power, the air inlet 112 is respectively communicated with the inner ring air outlet 113, the middle ring air outlet 115 and the outer ring air outlet 114 through ignition channels, and the air inlet is referred to as 7-9.
