The inner ring 4 is placed in the outer supporting portion 8, the outer diameter of the inner ring 4 is required to be not larger than the inner diameter of the outer supporting portion 8 so that the inner ring 4 can be placed freely, the lowest end of the inner ring 4 does not exceed the lowest end of the outer supporting portion 8, the shoulder 7 is supported on the outer ventilation platform 9 of the outer shell 1, therefore the bottom of the inner ring 4 can be free from contact with a gas stove, the shoulder 7 is in contact with the outer ventilation platform 9, the height of the shoulder 7 cannot be lower than 3cm, the width of the platform portion 6 is not smaller than 3cm, and the effect of the platform portion 6 is to increase heat reflection when the large pot is used, so that an energy-saving effect is generated.
The height of the shoulder 7 is limited so that the shoulder 7, the platform 6 and the external ventilation part form a cavity to generate swirling wind, so that the shoulder 7 is too low or the platform 6 is too narrow, and the formed cavity is too small to achieve the effect of swirling wind.
When a pan having a diameter larger than the maximum diameter of the inner housing 2 but smaller than the inner diameter of the upper end of the outer housing 1 is used, the pan body completely presses the inner housing 2, but the platform portion 6 of the inner housing 2 is inclined at an angle to the outer wall 10 of the general pan body because it is horizontally disposed, so that the ventilation holes a-114 of the platform portion 6 can also function.

The vent holes A-215 are arranged between the two anti-skid brackets 3, do not interfere with the fixation of the anti-skid brackets 3, do not affect the strength of the whole inner cover body 2, and are not limited to the above number; the ventilation hole B-1 and the ventilation hole A-215 form rotational flow, namely, under the action of the air draft of the exhaust fan, the outside air flows out from the ventilation hole A-215 through the ventilation hole B-1 in a rotating way to form a first layer of air flow, so that the effects of wrapping and energy gathering are achieved, the ventilation hole B-318 and the ventilation hole A-114 form a second layer of air flow, and the second layer of air flow is wrapped and energy gathering again.
It should be noted that when the outer diameter of the pan body is larger than the inner diameter of the outer shell 1, and the whole pan body completely covers the edge of the outer shell 1, at this time, the outside air enters the outer shell 1 through the vent holes B-217 to form a new air flow, and the effects of wrapping and energy gathering can be achieved as well.
