With the rapid development of economy, energy crisis and environmental pollution have become more and more serious social strategic issues. International regional conflicts are largely due to the redistribution of energy and the final solution to energy competition. Environmental pollution has affected human existence. Reducing pollutant emissions has become a primary issue that countries all over the world need to solve.

Gas cookers are widely used in people's daily life because of their cleanliness and ease of use. However, most of the existing gas cookers and range hoods are two separate kitchen utensils. The machine is hung in the space above the stove. The existing problems are: 1. The range hood takes up space and hinders the operation; 2. The distance between the range hood and the stove is large, the suction is not concentrated, and the suction rate is low; 3. The stove occupies the countertop and is difficult to clean, which affects the appearance; 4. The range hood and stove and the surroundings have oil fume adhered, and oil drips, so it is troublesome to disassemble and clean the range hood; 5. The range hood and stove are made of non-stick oil coating for easy scrubbing, and some stoves are made of heat-resistant explosion-proof glass , increased production costs.

In addition, the burners of the existing stoves are mostly large-diameter disc burners, and the air intake method is horizontal air intake. This kind of burner has the following disadvantages. First, the heat utilization rate is not high, and a large amount of heat energy is radiated and wasted. The second is that insufficient combustion has a large amount of CO and harmful gases to get rid of and pollute the environment.
