The first protrusions 123 are arranged at intervals along the circumferential direction of the outer ring portion 120. A first spacing groove 122 is provided between two adjacent first protrusions 123, and each first protrusion 123 is provided with at least one second fire hole 121. The inner ring portion 110 and the outer ring portion 120 form a height step, so that the flame on the first fire hole 111 of the inner ring portion 110 can be separated from the flame on the second fire hole 121 of the outer ring portion 120, thereby avoiding continuous flames, and the second fire holes 121 on the outer ring portion 120 are separated by the first spacing groove 122, so that the flames on each second fire hole 121 can also avoid continuous flames. By reducing continuous flames, the secondary air can be more fully supplemented during combustion and the combustion can be more complete, thereby improving the thermal efficiency of combustion and reducing the smoke content.

[0028] Specifically, the fire cover body 100 can be in a ring shape and can be provided with an inner ring portion 110 and an outer ring portion 120, both of which are in the shape of a circular ring, and there is a height difference between the upper end surface of the inner ring portion 110 and the upper end surface of the outer ring portion 120, and the inner ring portion 110 is higher than the outer ring portion 120, so that the inner ring portion 110 and the outer ring portion 120 have a step, and the inner ring portion 110 and the outer ring portion 120 can be an integrated structure, which can be made by casting, machining or stamping, and the upper end surface of the inner ring portion 110 can be provided with a plurality of first fire holes 111 that pass through from top to bottom, and the first fire holes 111 are used for flame ejection and combustion, and the outer ring portion 120 has a plurality of first protrusions 123, and the first protrusions 123 are arranged at intervals along the outer ring portion 120 and are evenly arranged in an annular direction, and the first protrusions 123 are arranged between them.

It can be understood that one second fire hole 121 or multiple second fire holes 121 can be set on each first protruding portion 123. Due to the first spacing groove 122, the upper second fire hole 121 of each first protruding portion 123 is separated by the first spacing groove 122, so that the flames passing through each first protruding portion 123 will not be connected, and there is a height difference between the inner ring portion 110 and the outer ring portion 120, so that the first fire hole 111 and the second fire hole 121 are separated in height, so that the flames in these two areas will not be connected, so that the secondary air is fully supplemented during combustion, so that the flame burns more fully under the fire distribution of the fire cover, thereby improving the thermal efficiency of combustion and reducing the smoke content generated by combustion.

[0029] Reference Figure 1 and Figure 3In some embodiments of the present invention, the first fire hole 111 is in the shape of an annular strip, and the first fire hole 111 is arranged at intervals inside and outside, which can facilitate the processing of the first fire hole 111.

[0030] Specifically, the shape of the first fire hole 111 can match the shape of the inner ring portion 110 and be in the shape of an annular strip. The first fire hole 111 can be cut and formed on the top surface of the inner ring portion 110, and the first fire hole 111 can be set to two, in an inner and outer circle. The shape of the first fire hole 111 can be easy to manufacture, and the fire cover can be rotated to cooperate with the cutting tool for cutting. Compared with the method of drilling holes one by one, the processing efficiency is faster.

[0031] It should be noted that the first fire hole 111 is not limited to the above embodiment, and other embodiments may be adopted. For example, the first fire hole 111 may be directly drilled, and the formed circular holes may be arranged at intervals along the circumferential direction of the inner ring portion 110 .

[0032] It is understandable that when the first fire hole 111 is processed, the fire cover can be fixed and the tool can be rotated to cut the inner ring portion to form the annular first fire hole 111 .

[0034] Specifically, the inner ring portion 110 may be provided with a plurality of second protrusions 113, and the second protrusions 113 may be evenly spaced around the inner ring portion 110 so that second spacing grooves 112 are formed between the second protrusions 113, and first fire holes 111 may be provided on the second protrusions 113. It can be understood that one first fire hole 111 or a plurality of first fire holes 111 may be provided on each second protrusion 113, and the second spacing grooves 112 can separate the flames passing through the first fire holes 111 on each second protrusion 113 so that they will not be connected, thereby improving the secondary air supplement effect of combustion, making combustion more complete, and further improving the combustion thermal efficiency of the fire cover.

[0035] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the first fire hole 111 is in a strip shape, and the first fire hole 111 is arranged to extend along the circumferential direction of the inner ring portion 110. This can facilitate the processing of the first fire hole 111.

[0036] Specifically, the first fire hole 111 can be directly cut on the upper end surface of the inner ring portion 110 to form a strip, and the setting direction is circumferential. During processing, the fire cover can be rotated so that the cutting tool can perform circumferential cutting relative to the fire cover, and the first fire hole 111 on each second raised portion 113 can be completed. The processing is convenient and efficient.

[0037] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the first fire hole 111 is arranged through the top wall and two side walls of the second protrusion 113, so that the second spacing groove 112 is directly connected to the first fire hole 111. It is convenient for air to enter from the second spacing groove 112 for replenishment, so that the combustion is more complete.

[0038] Specifically, when processing the first fire hole 111, the cutting depth can be increased so that the first fire hole 111 can penetrate the top wall and two side walls of the second protrusion 113, so that the first fire hole 111 can form an opening on the side wall of the second spacing groove 112, so that the first fire hole 111 can be directly connected to the second spacing groove 112. During combustion, air can enter through the second spacing groove 112 for replenishment, so that the flame at the first fire hole 111 can further burn fully.

[0039] Reference Figures 1 to 4 In some embodiments of the present invention, the second fire hole 121 is in a strip shape, and the second fire hole 121 is arranged to extend along the circumferential direction of the outer ring portion 120. This can facilitate the processing of the second fire hole 121.

[0040] Specifically, when processing the second fire hole 121, the fire cover can be rotated, and the cutting tool can cut on the top wall of the outer ring portion 120 to form a ring-shaped strip opening, and the opening is the second fire hole 121. When the fire cover rotates one circle, the second fire hole 121 can be cut on each second raised portion 113, and the processing efficiency is high.

[0041] It should be noted that the second fire hole 121 is not limited to the above embodiment, and other embodiments may be adopted. For example, the second fire hole 121 may be directly drilled, and the formed circular holes may be arranged at intervals along the circumferential direction of the inner ring portion 110 .

[0042] It is understandable that when processing the second fire hole 121 , the fire cover can be fixed and the cutter can be rotated to cut the outer ring portion to form the annular second fire hole 121 .

[0043] Reference Figures 1 to 4In some embodiments of the present invention, the second fire hole 121 is arranged through the top wall and two side walls of the first protrusion 123, so that the second fire hole 121 is directly connected to the first spacing groove 122.

[0044] Specifically, when processing the second fire hole 121, the cutting depth can be increased so that the cutting tool can penetrate the top wall and two side walls of the first protrusion 123, so that an opening can be formed on the side wall of the first spacing groove 122. During combustion, air can enter from the first spacing groove 122 and then flow to the second fire hole 121 for replenishment, so that the flame at the second fire hole 121 burns more fully.

[0045] Reference Figures 1 to 4 In some embodiments of the present invention, the first protrusion 123 is provided with an inclined surface 1231 , the inclined surface 1231 is located between the upper end surface of the first protrusion 123 and the outer side wall of the outer ring portion 120 , and the second fire hole 121 is provided on the inclined surface 1231 .

[0046] Specifically, the first raised portion 123 can be processed with a bevel 1231. During processing, the fire cover can be rotated, and the tool cuts the bevel 1231 on the outer ring portion 120. The second fire hole 121 can be cut on the bevel 1231, so that the second fire hole 121 on the bevel 1231 can be further separated from the second fire hole 121 on the second raised portion 113, which can not only improve the air supplement effect, but also make the combustion condition more stable.

[0047] Reference Figures 1 to 4 In some embodiments of the present invention, the angle between the inclined surface 1231 and the upper end surface of the first protrusion 123 is 45°. Specifically, a 45° cutting tool is easy to obtain and can facilitate the processing of the inclined surface 1231.

[0048] It should be noted that the specific angle of the inclined surface 1231 is not limited to the above embodiment, and other embodiments may also be adopted. For example, the angle between the inclined surface 1231 and the upper end surface of the first protrusion 123 may also be set to 60°.

[0049] According to the second aspect of the present invention, the gas stove includes a gas stove using the stacked flame cover. By using the stacked flame cover, the gas stove can be burned, through the flame division of the stacked flame cover, so that the first fire hole 111 and the second fire hole 121 can be fully supplemented with air. Since the secondary air is supplemented more fully, the gas stove can burn more fully, thereby improving the combustion thermal efficiency and reducing the smoke content.
