Description

Technical Field

[0001] This utility model relates to the field of gas stoves, and in particular to a stainless steel burner for gas stoves. Background Technology

[0002] In the gas stove burner market, aluminum is often used by manufacturers to reduce costs because it is easy to form and inexpensive.

[0027] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0028] Example 1: As Figures 1 to 7 As shown, this embodiment provides a stainless steel burner, including a base 1, a gas distribution plate 2, an inner flame cap 3, and an outer flame cap 4, wherein the gas distribution plate 2 is installed on the base, the inner flame cap 3 and the outer flame cap 4 are installed on the gas distribution plate 2, a first air intake channel 11 is formed at the bottom center of the base 1, and a second air intake channel 21 is formed at the center of the gas distribution plate 2.

[0029] A first connecting edge 12 extending downward is provided on the edge of the base 1. The outer flame cover 4 includes an inner slope 41 and an outer slope 42. A flame outlet 9 is provided on the outer slope 42. A second connecting edge 422 extending downward is provided on the edge of the outer slope 42. The second connecting edge 422 is closely attached to the outer side of the first connecting edge 12. The bottom of the second connecting edge 422 is bent inward to form a rolled edge structure 5. The rolled edge structure 5 is wrapped around the bottom of the first connecting edge 12.

[0030] The base 1, the gas distribution plate 2, the inner flame cover 3, and the outer flame cover 4 are all made of stainless steel.

[0031] This embodiment provides a stainless steel burner, which uses stainless steel material to increase the stability and service life of the burner. At the same time, the rolled edge structure 5 of the base 1 and the outer flame cap 4 can effectively prevent gas leakage, and the tight connection between the base 1 and the outer flame cap 3 can reduce the risk of gas leakage.

[0032] Specifically, the rolled edge structure 5 effectively increases the contact area between the base 1 and the outer flame cap 4. This contact area is sufficiently wide, and the rolled edge structure 5 makes the connection between the base 1 and the outer flame cap 4 more secure, allowing them to be more effectively fixed together. This effectively reduces air leakage between the base 1 and the outer flame cap 4. Furthermore, this structure effectively solves the problem of abnormal noise caused by flameout after combustion in sheet metal flame spreaders on the market.

[0033] Specifically, the rolled edge structure 5 is U-shaped and includes an upward-facing connecting groove 51. The bottom of the first connecting edge 12 is inserted into the connecting groove 51 and tightly connected to it. The open edge of the rolled edge structure 5 faces inward to the burner, keeping the burner exterior smooth and preventing scratches to the user.

[0034] Furthermore, a connecting seat 6 is provided at the center of the air distribution plate 2. The connecting seat 6 and the air distribution plate 2 are riveted together. An external thread 61 is provided on the outer edge of the open end of the connecting seat 6, and an internal thread 31 adapted to the external thread 61 is provided at the end of the inner burner cap 3. The inner burner cap 3 is detachably threaded together with the external thread 61 of the connecting seat 6 through its internal thread 31. This design not only fixes the connecting seat 6 and the air distribution plate 2 together, but also facilitates the disassembly and assembly of the inner burner cap 3 from the connecting seat 6, making disassembly and replacement convenient.

[0035] Preferably, an inner air intake pipe 7 is provided at the center of the air distribution plate 2, and a second air intake channel 21 is formed in the inner air intake pipe 7. A slot A 71 is provided on the outer edge of the end of the inner air intake pipe 7, and the inner air intake pipe 7, the air distribution plate 2, and the connecting seat 6 are connected together through the slot A 71. This facilitates the fixed installation of the inner air intake pipe 7 with the air distribution plate 2 and the connecting seat 6, and prevents air leakage from the inner air intake pipe 7.

[0036] Specifically, an external air intake pipe 8 is provided at the bottom center of the base 1, and the first air intake channel 11 is formed in the external air intake pipe 8. A slot B 81 is provided on the outer edge of the end of the external air intake pipe 8, and the external air intake pipe 8 and the base 1 are connected together through the slot B 81. This facilitates the fixed installation of the external air intake pipe 8 and the base 1 and prevents air leakage from the external air intake pipe 8. In addition, the burner forms a dual channel, with gas entering through two channels and burning on the inner burner cap 3 and the outer burner cap 4 respectively, which allows the user to adjust the flame size as needed.

[0037] Furthermore, the flame outlet 9 includes a first group of flame outlets 91 and a second group of flame outlets 92 distributed circumferentially. The first group of flame outlets 91 includes several upper flame outlets 911 near the upper edge of the outer slope surface 42, and the second group of flame outlets 92 includes several lower flame outlets 921 near the lower edge of the outer slope surface 42. The upper flame outlets 911 and the lower flame outlets 921 are staggered and spaced apart. Because the first group of flame outlets 91 forms equidistant blocks that avoid the furnace ears, when the gas is burned, the flame is prevented from directly burning the furnace ears, effectively reducing flue gas emissions and improving thermal efficiency.

[0038] Furthermore, the length of the upper flame outlet 911 is greater than the length of the lower flame outlet 921. The upper flame outlet 911 is closer to the cookware, allowing for greater movement at the upper flame outlet 911, while the flame from the lower flame outlet 921 is slightly smaller, which helps to save gas usage.

[0039] Furthermore, the burner is made of stainless steel, which increases its stability and service life.

[0040] Furthermore, the inner flame cap 3 has several internal flame outlet holes 32 at its columnar portion, allowing the inner flame cap 3 to better burn the combustion gases.

[0041] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
