Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Generally, when a traditional gas stove works, the gas pressure in front of a nozzle is the pressure required by national standards or lower, so that the kinetic energy of the gas ejected from the nozzle is not high, the air quantity injected into a combustor is not enough to the required quantity for complete combustion, namely the excess air coefficient is less than 1, so that insufficient combustion is caused, the content of harmful gases (CO and NOX) in smoke is high, and the harmful gases are harmful to the health of a user and pollute the environment.
Referring to fig. 1 or 2, fig. 1 shows a schematic structural diagram of a gas control device according to an embodiment of the present invention, and fig. 2 shows a schematic structural diagram of a gas control device according to another embodiment of the present invention. An embodiment of the present invention provides a gas control device, including: the gas inlet device comprises a gas inlet main pipe 10, a first branch pipe 20, a main injection pipe 30, a pressurizing mechanism 40 and a combustor 50.
When the gas control device works, the gas inlet main pipe 10 sends gas into the first branch pipe 20, the pressurizing mechanism 40 enables the gas of the first branch pipe 20 to increase pressure, the gas with increased pressure is conveyed into the main injection pipe 30 through the first nozzle 21, the main injection pipe 30 introduces the gas into the outer ring main chamber 51, and the gas is uniformly mixed in the outer ring main chamber 51 of the combustor 50 and then is sprayed out and combusted through the outer ring main fire holes 52. Because the gas on the first branch pipe 20 has been through the pressurization, when spouting main injection pipe 30 from first nozzle 21, kinetic energy increase, consequently the air that the nature was penetrated can increase relatively, and general surplus air coefficient all can be greater than 1, consequently can the abundant burning, harmful gas content in the flue gas can reduce, reaches the purpose of environmental protection.
Referring to fig. 2, the burner 50 further includes an outer ring auxiliary chamber 53 and a plurality of outer ring auxiliary fire holes 54 communicated with the outer ring auxiliary chamber 53. The gas control device further comprises a second branch pipe 60 and an auxiliary injection pipe 70. One end of the second branch pipe 60 is communicated with the intake manifold 10, and the other end of the second branch pipe 60 is provided with a second nozzle 61. The second nozzle 61 is arranged opposite to the air inlet end of the auxiliary injection pipe 70, and the air outlet end of the auxiliary injection pipe 70 is communicated with the outer ring auxiliary chamber 53.
So, gas controlling means is at the during operation, and more than the main fire hole 52 of foretell outer loop has the gas burning, and simultaneously, main intake manifold 10 can send the gas into second branch road pipe 60 in step, and the gas in second branch road pipe 60 is the ordinary pressure, jets into supplementary injection pipe 70 through second nozzle 61, and supplementary injection pipe 70 draws the gas to introduce the outer loop auxiliary chamber 53 naturally in, after the misce bene in the outer loop auxiliary chamber 53 of combustor 50, the supplementary fire hole 54 of outer loop outwards spouts the burning.
The excess air coefficient of the gas naturally introduced into the outer ring auxiliary chamber 53 is low, the flow rate of the gas and air mixture flowing out of the outer ring auxiliary fire hole 54 is low, the flame leaving phenomenon cannot occur, meanwhile, the gas and air mixture acts as a flame stabilizing effect on the main flame near the outer ring main fire hole 52, the combustion is stable, the flame leaving phenomenon or even the flameout phenomenon on the outer ring fire cover can be avoided, and the gas and air mixture is most obvious particularly in a cold state. In addition, the mixed gas flowing out of the outer ring main fire holes 52 is pressurized, so that the kinetic energy of the gas sprayed out of the first nozzle 21 is increased, the injected air is relatively increased, the coefficient of the excess air is larger than 1, and the gas is combusted to form a light flame, and the mixed gas flowing out of the outer ring auxiliary fire holes 54 and not pressurized is compared with the mixed gas flowing out of the outer ring main fire holes 52, the coefficient of the excess air is smaller than 1, and the mixed gas is combusted to form a thick flame, so that the outer ring main fire holes 52 and the outer ring auxiliary fire holes 54 form thick-thin combustion, and the generation of NOx is also reduced. The aim of reducing the emission of harmful gases is achieved.
In one embodiment, a plurality of outer ring main fire holes 52 and a plurality of outer ring auxiliary fire holes 54 are alternately arranged on the combustor 50.

Thus, the outer ring auxiliary fire holes 54 are located adjacent to the outer ring main fire holes 52, so as to provide a good flame stabilizing effect for the main flame, so that the combustion is stable, and the phenomenon of flame separation and even flameout on the outer ring fire cover in a cold state can be avoided.
Specifically, the outer ring main fire holes 52 are closer to the central fire holes 56 of the burner 50 than the outer ring auxiliary fire holes 54, that is, the outer ring auxiliary fire holes 54 are farther from the central fire holes 56 of the burner 50 than the outer ring main fire holes 52, so that the outer ring auxiliary fire holes 54 can be more sufficiently contacted with the secondary air, and the gas combustion of the outer ring auxiliary fire holes 54 is more sufficient. Further, a plurality of outer ring main fire holes 52 are circumferentially arranged at equal intervals centering on the center of the combustor 50, and a plurality of outer ring auxiliary fire holes 54 are circumferentially arranged at equal intervals centering on the center of the combustor 50.
It should be noted that the outer ring auxiliary chamber 53 and the outer ring main chamber 51 are isolated from each other. When the outer ring auxiliary fire holes 54 are farther from the central fire holes 56 of the combustor 50 than the outer ring main fire holes 52, the outer ring auxiliary chamber 53 is farther from the central fire holes 56 of the combustor 50 than the outer ring main chamber 51.
As an alternative, the outer ring main fire holes 52 may be located farther from the central fire holes 56 of the combustor 50 than the outer ring auxiliary fire holes 54, that is, the outer ring auxiliary fire holes 54 are located closer to the central fire holes 56 of the combustor 50 than the outer ring main fire holes 52.
