An air deflector is arranged in the annular cavity, and sieve-shaped ventilation holes are evenly distributed on the inner surface of the cover. The inner surface of the cover is Equipped with pot bottom support frame.

The beneficial effect of the utility model is that: the center of the circular hole in the inner layer of the cover is the cooker head, and the arc-shaped pot body in the inner layer of the cover makes the cover body prevent flame extension, prevent wind and reflect scattered heat to the bottom of the pot; the cover The annular cavity in the body, the air deflector in the annular cavity and the ventilation hole on the inner surface of the cover can not only increase the lift of fresh air, increase the air flow through the ventilation hole, but also drive away the burned carbon dioxide and replenish it in time. Oxygen combustion; the cylindrical shape of the outer layer of the cover not only assists the role of the air deflector, but also prevents the heat loss of the cooker; the support legs of the cover and the bottom support frame are mainly to assist oxygen combustion to avoid insufficient combustion of gas air pollution caused.

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the air deflector is vertically connected to the inner layer of the cover and the outer layer of the cover, and the lower edge of the air deflector, the lower edge of the inner layer of the cover and the lower edge of the outer layer of the cover are flush.

Further, the thickness of the air deflector is 1-1.5 mm.

Further, the distance between the air deflectors is 15-20 mm.

Further, the ventilation holes in the inner layer of the cover are arranged in rows along the direction of the air deflector.

Further, the diameter of the air hole is 1-2 mm.

Further, there are three cover legs and they form 120° with each other, and the cover legs are fixedly connected with the air deflector at the corresponding position or with the outer layer of the cover.

Further, the upper edges of the inner layer of the cover and the outer layer of the cover are connected by an arc.

The beneficial effect of adopting the above further scheme is that a large amount of fresh air can be ensured to enter between the air deflectors of the annular cavity, pass through the sieve-shaped ventilation holes on the inner surface of the cover, and drive away the burned carbon dioxide under the flame, and supply oxygen for the second time. It compensates for the phenomenon of oxygen-deficient combustion of combustible gas, and at the same time ensures the stability of the cover when it is placed around the stove.

Further, the pot bottom support frame is made of heat-resistant steel.

Further, the cover is made of steel plate or composite material of steel and high temperature resistant ceramics.

The beneficial effect of adopting the above-mentioned further scheme is that the support frames at the bottom of the pot are three at an angle of 120 degrees to each other, the support frames at the bottom of the pot are made of heat-resistant steel and the cover body is made of steel plates and high-temperature-resistant ceramic composite materials, which can not only increase the load-bearing capacity , It also has strong stability against high temperature, corrosion and oxidation.
