[0027] Reference Figure 1 , Figure 2 and Figure 3 A central flame cap includes a flame cap body 100 and a top cover 200. The top cover 200 is located on the upper side of the flame cap body 100 and defines a central gas cavity 300 between the top cover 200 and the flame cap body 100. The top cover 200 is provided with at least two protrusions 210. Multiple protrusions 210 are stacked longitudinally and their radial dimensions decrease from bottom to top. Each protrusion 210 is provided with multiple first flame holes 201. One end of the first flame hole 201 communicates with the central gas cavity 300, and the other end is located on the peripheral sidewall of the protrusion 210. Multiple first flame holes 201 of the same protrusion 210 are evenly spaced along the circumference of the protrusion 210.

[0028] Understandably, such as Figure 1 , Figure 2 and Figure 3As shown, the top cover 200 is provided with two protrusions 210. The protrusions 210 are roughly cylindrical in shape. The two protrusions 210 are stacked in the vertical direction. The radial dimension of the protrusion 210 on the lower side is larger than that of the protrusion 210 on the upper side. Each protrusion 210 is provided with a plurality of first flame holes 201. The input end of the first flame hole 201 is connected to the central gas chamber 300, and its output end is located on the peripheral side wall of the protrusion 210. In use, the central burner cap is positioned in the middle of the burner head, and the central gas passage is connected to the central gas chamber 300, allowing gas to be delivered to the central gas chamber 300 and output for combustion through the first flame hole 201. Because the top cover 200 has multiple stacked protrusions 210, and the radial dimensions of these protrusions decrease from bottom to top, a tower-like structure is formed on the top cover 200. Each protrusion 210 is surrounded by multiple first flame holes 201, placing the multiple first flame holes 201 at different heights in each layer, creating intervals in both the horizontal and vertical directions. The height difference of the first flame holes 201 in the vertical direction facilitates better air replenishment. The protrusion 210 at the center is at the highest level, allowing for convenient external air replenishment to the center, which is beneficial for achieving complete combustion of the gas output from the center of the top cover 200, ensuring thermal efficiency, and avoiding energy waste.

[0029] In practical applications, the boss 210 can be provided with three or more, and the specific number of the first fire hole 201 can be set according to the actual needs of use.

[0030] In some embodiments, in two adjacent bosses 210, a plurality of first fire holes 201 on the lower boss 210 and a plurality of first fire holes 201 on the upper boss 210 are alternately distributed around the axis of the top cover 200.

[0031] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first flame holes 201 on the lower boss 210 are not aligned longitudinally with the first flame holes 201 on the upper boss 210. They are alternately distributed around the axis of the top cover 200, causing the upper and lower layers of first flame holes 201 to be misaligned. This achieves better fire coverage and facilitates air replenishment. In practical applications, the specific distribution of the first flame holes 201 on the boss 210 can be adjusted according to actual usage requirements.

[0032] In some embodiments, the outer periphery of the boss 210 is provided with an extended protrusion 211, the first protrusion 211 being located above the gas outlet end of the first flame hole 201. It is understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer periphery of the boss 210 is provided with an outwardly extending first protrusion 211. The first protrusion 211 is located above the gas outlet end of the first burner hole 201, forming a roof-like shielding structure. This reduces the possibility of foreign objects entering the first burner hole 201 from above, helping to avoid clogging the first burner hole 201 and preventing water accumulation inside the burner, thus facilitating use. In practical applications, the specific structure of the first protrusion 211 can be varied according to actual usage needs.

[0033] In some embodiments, the top cover 200 is detachably connected to the flame cap body 100. It is understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the top cover 200 can be detached from the flame cap body 100. During manufacturing, the top cover 200 and the flame cap body 100 can be processed separately. This split structure reduces processing difficulty and facilitates the manufacturing of the central flame cap. In use, different top covers 200 can be replaced as needed to change the combustion heating effect on the upper side of the central flame cap, improving adaptability and ease of use. In practical applications, the top cover 200 and the flame cap body 100 can also be an integral structure. Besides the structure shown in the diagram, the flame cap body 100 can also be a simple ring structure, depending on the specific application requirements.

[0034] In some embodiments, the lower side of the top cover 200 is provided with a downwardly extending protruding first positioning ring 220, and the upper side of the flame cap body 100 is provided with an upwardly extending protruding second positioning ring 110. The top cover 200 is detachably placed on the upper side of the flame cap body 100 and the first positioning ring 220 and the second positioning ring 110 are fitted together.

[0035] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a first positioning ring 220 is provided on the lower side of the top cover 200, and a second positioning ring 110 is provided on the upper side of the flame cap body 100. During assembly, the top cover 200 is placed on the upper side of the flame cap body 100, and the first positioning ring 220 and the second positioning ring 110 are fitted together. The first positioning ring 220 is inserted into the inner side of the second positioning ring 110, and the outer wall of the first positioning ring 220 contacts the inner wall of the second positioning ring 110, thereby restricting the horizontal movement of the top cover 200 relative to the flame cap body 100 and realizing the installation fit between the two. Its structure is simple and convenient for production, assembly and use. In practical applications, in addition to the above structure, the top cover 200 and the flame cap body 100 can also be detachably connected by a threaded structure, which can be set according to the actual use needs.

[0036] In some embodiments, the outer periphery of the flame cap body 100 is provided with a plurality of second flame holes 101, which communicate with the central gas cavity 300. It is understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple second flame holes 101 are evenly spaced along the circumference of the burner cap body 100. By setting the second flame holes 101, the central burner cap can be heated by both the top flame and the outer peripheral flame, which helps to improve the heating capacity of the burner at the central burner cap and facilitates cooking. In actual applications, the specific number and distribution of the second flame holes 101 can be set according to actual usage needs.

[0037] Furthermore, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer periphery of the burner cap body 100 is provided with multiple flame stabilizing holes 102. The flame stabilizing holes 102 are connected to the central gas chamber 300 and their outlet ends are provided with flame stabilizing grooves 103. The flame stabilizing grooves 103 are annular and are connected to the outlet ends of multiple flame stabilizing holes 102. The flame stabilizing grooves 103 are located below the second burner hole 101, which helps to assist the combustion of the gas output from the second burner hole 101 and achieve the effect of flame stabilization.

[0038] In some embodiments, the flame cap body 100 is provided with a partition 120, which is located in the central air cavity 300 and can divide the central air cavity 300 into a first air cavity 301 and a second air cavity 302. The first flame hole 201 communicates with the first air cavity 301, and the second flame hole 101 communicates with the second air cavity 302.

[0039] Understandably, such as Figure 2 , Figure 3 and Figure 4As shown, the dividing part 120 is located in the central gas cavity 300, and its overall structure is roughly funnel-shaped. The dividing part 120 divides the central gas cavity 300 into a first gas cavity 301 and a second gas cavity 302. The inner and upper sides of the funnel-shaped structure are the first gas cavity 301, and the outer side of the funnel-shaped structure is the second gas cavity 302. The first flame hole 201 communicates with the first gas cavity 301, and the second flame hole 101 communicates with the second gas cavity 302. In use, the gas supply to the first gas cavity 301 and the second gas cavity 302 can be controlled separately to achieve separate control of the flame at the top of the central burner cap or the flame on the outer periphery, so as to adapt to different combustion heating needs. In practical applications, the dividing part 120 can also be located on the top cover 200, or the dividing part 120 can be detached from the burner cap body 100 and the top cover 200. The specific structure and setting position of the dividing part 120 can be changed according to the actual use needs.

[0040] In some embodiments, the outer periphery of the flame cap body 100 is provided with an extended protrusion 130, the second protrusion 130 being located above the gas outlet end of the second flame hole 101. It is understood that, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer periphery of the burner cap body 100 is provided with an outwardly extending second protrusion 130. The second protrusion 130 is located above the gas outlet end of the second burner hole 101, forming a roof-like shielding structure. This reduces the possibility of foreign objects entering the second burner hole 101 from above, helping to avoid clogging the second burner hole 101 and preventing water accumulation inside the burner, thus facilitating use. In practical applications, the specific structure of the second protrusion 130 can be varied according to actual usage needs.
