Background technique

The so-called gas cooker refers to kitchen utensils heated by direct fire with gaseous fuels such as liquefied petroleum gas, artificial gas, and natural gas. Gas stoves are also called hobs, and their popularity is known to everyone, but it is difficult to see a common concept. Just like firewood stoves, kerosene stoves, coal pellet stoves and so on. According to the source of gas, gas stoves are mainly divided into liquefied gas stoves, gas stoves, and natural gas stoves. According to the focal point, it can be divided into single focal point, double focal point and multiple focal point. Gas stoves have become an essential cooking tool for families and restaurants. On the one hand, gas stoves are easy to use and do not need to burn wood like traditional firewood stoves. On the other hand, gas stoves cause less air pollution.

In the gas cooker of the prior art, the stove core usually adopts a structure of multiple nozzles. The shortcoming of this structure is that the nozzles are small and are easily damaged during use (after a certain amount of alcohol-based fuel is burned, the nozzles become larger, and the flame is weak and hits the kitchen. Oil stains are easy to block), and when the fire is small, there will be misfire phenomenon, which has potential safety hazards, and the combustion efficiency is low, the gas cannot be fully mixed with the air, resulting in low combustion efficiency of the gas, low flame temperature, and poor flame temperature uniformity Well, serious waste.
