Description

Technical Field

[0001] The utility model relates to the field of gas stoves, in particular to a burner head and a gas stove. Background Art

[0002] The existing one-piece aluminum burner is formed by die-casting, and the burner and the gas distribution plate are connected as one. There are two types: one is that the connection between the inner ring and the outer ring is hollowed out, commonly known as "heaven and earth through". However, the "heaven and earth through" type of burner has a significant effect in reducing the temperature rise inside the stove and replenishing secondary air, but the large through hole is not conducive to preventing liquid overflow. In the event of an overflow in the pot during use, the liquid can easily flow into the inside of the stove, which is not conducive to cleaning.

[0003] The other design is to seal the connection between the inner and outer rings. This burner design prevents liquid from flowing into the stove in the event of an overflow. However, since there are no effective through-holes in the burner, the stove cannot effectively dissipate heat, and the temperature rise of internal components can easily exceed the standard, shortening the service life. To meet the temperature rise requirements, the load of liquefied gas models cannot be increased. Utility Model Content

The side wall of the burner base 1 is provided with an oxygen supply hole 7, and the oxygen supply hole 7 is connected to the sunken groove 2 space. The bottom of the groove 2 is provided with oxygen supply holes 8 around the central tube. The other end of the oxygen supply hole 8 is located at the bottom of the burner base 1. The oxygen supply hole 8 forms an oxygen supply channel, so that the outside air directly enters the space of the groove through the bottom of the burner base 1 to supply oxygen to the combustion of the center fire. Preferably, a plurality of oxygen supply holes 8 can be provided. The function of the oxygen supply hole 8 is to form an oxygen supply channel to help the outside air circulate into the space of the groove 2, reduce the temperature rise inside the stove, and also supply oxygen to the center fire. Figure 7 The path indicated by the arrow in FIG. 1 is a schematic diagram of the flow path of the air in the burner base 1 entering the groove through the oxygen supply channel.

[0029] refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 7 In a preferred embodiment, a raised shielding portion 9 is provided on the outer wall of the central tube 3, and the shielding portion 9 is located directly above the oxygen supply through hole 8. The shielding portion 9 is formed in a ring around the outer circumference of the central tube 3 to form a ring-shaped brim structure. The shielding portion 9 completely covers the oxygen supply through hole 8, and there is a gap between the shielding portion 9 and the oxygen supply through hole 8. When overflow occurs, the brim will block the overflowing liquid in the pot and the liquid will drip onto the shielding portion 9 instead of dripping into the oxygen supply through hole 8. The overflowed liquid cannot enter the interior of the cooker through the oxygen supply through hole 8, which has the effect of preventing splashing and overflow.

[0030] Preferably, the bottom of the groove 2 is set as an inclined surface with a high middle and low edges. When overflow occurs, if a large amount of liquid overflows from the pot, the inclined bottom surface of the groove 2 is set so that the liquid dripping from the edge of the brim to the bottom of the groove will not flow back into the oxygen supply hole 8.

[0031] refer to Figure 6 and Figure 7 In a preferred embodiment, an annular step 10 is provided around the center tube 3 on the bottom of the groove 2, that is, the top of the annular step 10 is higher than the plane of the bottom of the groove 2, thereby forming a partition, and the oxygen supply through hole 8 is located on the inner side of the ring of the annular step 10, and the shielding portion 9 completely covers the annular step 10. There is a gap between the shielding portion 9 and the annular step 10, and the annular step 10 separates the oxygen supply through hole 8 from the area not covered by the shielding portion 9 in the groove 2. When overflow occurs, if a large amount of liquid overflows from the pot, the liquid dripping onto the bottom of the groove 2 is blocked by the annular step 10 in the area not covered by the shielding portion 9, so that the liquid will not flow to the inner side of the ring of the annular step 10 where the oxygen supply through hole 8 is located.

[0032] In a preferred embodiment, a removable annular bottom plate (not shown) is provided at the bottom of the recess 2. The shape of the bottom plate matches that of the recess 2. The bottom plate is located below the shielding portion 9 to catch any liquid that drips from the shielding portion 9. In the event of a pot overflow, the brim of the cap blocks the overflow, allowing the liquid to drip down the edge of the brim onto the bottom plate. This prevents the overflowed liquid from flowing from the uncovered area of ​​the shielding portion to the area where the oxygen supply hole 8 is located, preventing the overflowed liquid from entering the interior of the cooktop through the oxygen supply hole 8.

[0033] In a preferred embodiment, the bottom surface of the second gas pipe where it connects to the outer ring combustion chamber 52 is a spirally upward slope. This spiral arrangement provides a better transition, allowing for smooth flow of gas from the second gas pipe into the outer ring combustion chamber 52 with minimal obstruction. It also leaves more space on the side of the base for the oxygen-enriching holes 7, helping the central combustion chamber 51 to receive more oxygen from the air.

[0034] In a preferred embodiment, a lighter is provided on the burner base 1. A mounting groove is provided on the side wall of the central tube, and the lighter is fixed in the mounting groove.

[0035] In a preferred embodiment, a flame detection needle is provided on the burner base 1, and a mounting groove is provided on the side wall of the central tube, and the flame detection needle is fixed in the mounting groove.

The ejector pipe outlet is connected to the burner's gas pipe inlet, and the damper plate 12 is fixed to the ejector pipe inlet. Optionally, the ejector pipe is die-cast and mated to the burner base 1 and then screwed in place. The damper plate 12 is die-cast and positioned at the bell mouth of the ejector pipe. It is screwed to the bell mouth and serves to secure the nozzle.

[0038] This invention provides an oxygen supply hole 8 below the center flame in the burner base 1, facilitating air flow and effectively reducing the internal temperature rise of the stove while supplying oxygen to the center flame. Furthermore, in the event of a pot overflow, the shielding portion 9 blocks the overflow, preventing the spilled liquid from entering the stove through the oxygen supply hole 8, thus preventing spillage and maintaining cleanliness. This solves the problem of internal temperature rise in gas stoves and preventing spilled liquid from flowing into the stove, making it difficult to supply oxygen to the center flame.
