Description

Technical Field

[0001] The utility model relates to a gas burner head with sufficient combustion. Background Art

[0002] The gas burner mainly mixes gas and air, and then outputs the mixed gas through the fire cover for combustion. Whether the gas burner can fully burn the gas is an important indicator for judging the quality of the burner. For this reason, the burner manufacturers continue to improve the appearance of the gas burner, hoping that the outside air can more easily enter the combustion area of ​​the gas and provide sufficient oxygen for the gas combustion. However, with the emergence of windproof stove racks, it is difficult for the outside air to enter the combustion area of ​​the gas. The current common practice is to solve this problem by fully pre-mixing oxygen and gas in the early stage. Although there is a certain effect, it is still difficult to solve the problem of air entering the combustion area.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the structure of the gas burner head of this embodiment;

[0013] Figure 2 for Figure 1 A is an enlarged view of the middle image. DETAILED DESCRIPTION

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0015] Please see attached Figure 1-2 The utility model provides a gas stove with sufficient combustion, which includes a stove base and a windproof grate 1. An outer ring air cavity 2 and a central air cavity 3 are arranged on the stove base. The central air cavity is arranged in the middle of the outer ring air cavity. An outer ring fire cover 4 and a central fire cover 5 are respectively covered on the outer ring air cavity 2 and the central air cavity 3. An inner ring air duct 7 is arranged on the bottom plate 6 of the stove base. The inner ring air duct is located between the outer ring air cavity 2 and the central air cavity 3. A plurality of first air outlet holes 8 are circumferentially distributed on the top of the inner ring air duct 7. The first air outlet hole can output fresh air from the outside to supplement oxygen for the area between the outer ring air cavity and the central air cavity, so that the gas can burn more fully. The first air outlet hole is in a trumpet shape with a wide outside and a narrow inside. The windproof grate 1 is arranged around the outer ring air cavity 2. The first air outlet hole adopts a design of a wide outside and a narrow inside, which can reduce the output wind pressure and disperse quickly to avoid excessive wind speed affecting the flame.

[0016] The inner annular air duct 7 is connected to an air inlet pipe 9, and a hole for the air inlet pipe to pass through is opened on the bottom plate 6 of the furnace head base. The air inlet pipe can be connected to a blowing device, and the blowing device can specifically be a blower.

[0017] The aperture of the smaller end of the first air outlet 8 is 0.8MM-1.5MM, preferably 0.8MM, 1.0MM, 1.2MM and 1.5MM, which is selected according to actual needs. Within this aperture range, the output air volume can be ensured, and foreign matter can be prevented from entering the inner annular air duct through the first air outlet.

[0018] The inner annular air duct 7 is provided with a connecting ear, which is fixed to the bottom plate 6 of the burner base by screws. The screw installation and fixing has the advantages of easy installation and disassembly.

[0019] An outer annular air duct 10 is arranged on the bottom plate 1 of the burner base, and the outer annular air duct is located between the outer annular air cavity 2 and the windproof grate 1. A plurality of second air outlets are circumferentially distributed on the top of the outer annular air duct. The function of the outer annular air duct is the same as that of the inner annular air duct, and will not be repeated here.

[0020] The outer annular air duct 10 is connected to the inner annular air duct 7 and is connected via a main air duct, which is connected to the blowing device.

[0021] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment.
