Embodiment Construction
[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0028] Generally, when a traditional gas stove is working, the gas pressure in front of the nozzle is the pressure required by the national standard or lower, so the kinetic energy of the gas injected from the nozzle is not high, and the amount of air injected into the burner cannot achiev...

The invention relates to a gas control device and a gas stove. The gas control device comprises a gas inlet main pipe, a first branch pipe, a main injection pipe, a pressurization mechanism and a combustor, wherein one end of the first branch pipe communicates with the air inlet main pipe, and the other end of the first branch pipe is provided with a first nozzle. When the gas control device works, gas is fed into the first branch pipe through the gas inlet main pipe, the pressure of the gas in the first branch pipe is increased through the pressurization mechanism, the gas with the increased pressure is conveyed into the main injection pipe through the first nozzle, the gas is introduced into an outer ring main cavity through the main injection pipe, and after the gas is evenly mixed in the outer ring main cavity of the combustor, fire is sprayed outwards through outer ring main fire holes for combustion. Due to the fact that the gas on the first branch pipe is pressurized, the kinetic energy is enlarged when the gas is sprayed to the main injection pipe from the first nozzle, naturally injected air is relatively increased, the coefficient of excess air is generally larger than 1 so that sufficient combustion can be achieved, the content of harmful gas in smoke can be reduced, and the purpose of environmental protection is achieved.
Description
technical field [0001] The invention relates to the technical field of stoves, in particular to a gas control device and a gas stove. Background technique [0002] With the rapid development of stoves, gas stoves have become an indispensable electrical product for families and are used for cooking in life. There are strict requirements for the inlet pressure of gas stoves, that is, the rated inlet pressure: 2000Pa for natural gas stoves, 2800Pa for liquefied petroleum gas stoves, and 1000Pa for artificial gas stoves. The inside of the traditional gas stove is only equipped with a fire regulating valve or a pressure reducing valve (such as a proportional valve of an intelligent control stove, which has a pressure reducing function), and most of them adopt the working mode of atmospheric combustion with natural injection. However, the traditional gas stove has the defect of insufficient combustion of gas, and then the content of harmful gases (CO, NOX) in the flue gas will be...
