At present, the fire cover of a gas stove usually comprises an inner ring fire cover and an outer ring fire cover, the heating mode of the fire cover to a pot body is basically the mode of combining an outer ring flame and an inner ring flame, but the center of the fire ring still has no flame, which can cause the heating effect of the center position of the pot bottom to be poor, therefore, the applicant provides an inner ring fire cover which can integrate an inner ring and a middle ring into a whole and can vertically and upwardly directly spray burning flame, and the burner of the domestic gas stove, like the Chinese utility model with the patent number ZL201420412292.5 (the granted number is CN204063043U), the body of the fire cover is provided with an inner ring wall and an outer ring wall, a central through hole is formed in the center of the inner ring wall, an annular channel is formed between the inner ring wall and the outer ring wall, a through hole is formed at the bottom of the annular channel, and the upper cover is of a sheet structure with meshes, the structure can lead the combustion of the inner ring fire cover to be concentrated, and the heat loss brought away by the secondary air is less, so the combustion temperature is higher, and the heat efficiency is better; however, since the inner ring fire cover is directly injected vertically upwards, the flow rate of the mixed gas is too high, so that the center of the cooker is easily blackened, and further improvement of the burner is needed.
In addition, with the development of urban gas industry, the kitchen range industry in China is greatly improved in the aspects of variety, material, performance, sales and the like. The important point in improving the performance is the improvement of the thermal efficiency. The burners of domestic gas cookers are atmospheric burners. The atmospheric burner is designed according to a partial premixing mode, and the primary air coefficient of the atmospheric burner is 0< alpha < 1. The atmospheric burner is divided into a head part and an ejector. The ejector is used for ejecting primary air required by combustion, and the head of the burner is used for uniformly distributing a gas-air mixture to the fire holes and carrying out stable and complete combustion. The gas of the gas stove mainly uses liquefied petroleum gas, natural gas, methane and the like, which are primary energy sources. Taking natural gas as an example, the usage amount of natural gas in China is increasing every year, and some of the natural gas is used for household gas. The majority of household gas is consumed in the cooking utensils, so that the heat efficiency of the cooking utensils is improved, the consumption of gas resources and the emission of greenhouse gas can be reduced, the gas cost of users can be reduced, and the air quality is improved. Therefore, the improvement of the efficiency of the gas stove is one of the struggle targets of the stove industry in China. In the actual use process of the existing gas stove, because a pot is placed on a pot support for heating, and a certain space interval is formed between the pot and a burner, the heat energy generated by gas combustion is used for heating the pot, and a considerable part of the heat energy is dissipated to the surrounding environment, so that energy waste is caused; in order to solve the above problems, heat collection and energy collection are provided in China in recent years, for example, "an energy collection ring for a gas stove and a gas stove with the energy collection ring" disclosed in chinese patent CN203404823U and "an energy collection type gas stove" disclosed in chinese patent CN204042984U, the gas stove is also provided with an energy collection pot support, although the energy collection ring structure can reduce the consumption of heat energy to a certain extent, the gas stove is generally placed in a ventilation place of a kitchen, when the wind force in the external environment is large, the combustion flame of the gas stove may swing and be unstable, sometimes even flameout, and the use is affected. In addition, the existing common gas stove has the phenomena of flameout, ignition failure and the like caused by sliding a pot, overflowing cooking soup into a burner head, a fire hole and the like of a burner.
