AI Technical Summary
The existing burner's inner and outer ring flame cap design results in uneven heat distribution, reducing the stove's thermal efficiency and requiring a taller pot rack design, which affects user experience and appearance.
The outer ring of the burner cap is designed with a smaller angle between the flame holes and the horizontal plane than the inner ring of the burner cap. This reasonable distribution of flame hole angles concentrates the heat of the flames at the bottom of the pot, resulting in more even heating and allowing the pot rack to be designed to be lower.
It improves the combustion thermal efficiency of gas stoves, enhances their aesthetic appearance, and improves the user experience.

[0040] As shown in Figures 3 to 5 The burner 100 comprises an outer ring fire cover 110 and an inner ring fire cover 120, the outer ring fire cover 110 is arranged at the outer periphery of the inner ring fire cover 120. The upper surface of the outer ring fire cover 110 is higher than the upper surface of the inner ring fire cover 120, the inner ring surface of the outer ring fire cover 110 is provided with a first fire hole 111 towards the center of the burner 100, and the inner ring surface of the inner ring fire cover 120 is provided with a second fire hole 121 towards the center of the burner 100, and the included angle between the direction of the first fire hole 111 and the horizontal plane is smaller than the included angle between the direction of the second fire hole 121 and the horizontal plane.
[0041] The burner 100 can reasonably distribute the fire hole angles of the inner ring fire cover 120 and the outer ring fire cover 110, so that the flame heat is concentrated and distributed on the pot bottom heating surface, a good energy concentration effect is achieved, the pot is heated more uniformly, the combustion heat efficiency of the gas stove is improved, and the energy concentration effect is good under the premise of allowing the pot rack 150 to be designed to be lower, the appearance is improved, and the user's use experience is improved.
[0042] Optionally, as shown in Figure 4 and Figure 5As shown, the orientation of the first fire hole 111 is horizontal, that is, the included angle between the orientation of the first fire hole 111 and the horizontal plane is 0°, and the orientation of the second fire hole 121 is inclined upward, that is, the included angle between the orientation of the second fire hole 121 and the horizontal plane is greater than 0°. Under this structure, the height of the inner ring fire cover 120 is low and the second fire hole 121 is arranged obliquely upward, so that a flame that directly hits the bottom of the pot can be formed. The first fire hole 111 of the outer ring fire cover 110 is horizontally arranged towards the center of the burner 100, forming a planarly extended flame. The flames of the upper and lower two parts of the fire cover jointly form a relatively flat flame surface, so that the flame heat can be concentratedly distributed on the heating surface of the pot bottom, thereby improving the combustion heat efficiency of the stove; and the pot rack 150 can be designed to be lower, and a good energy concentration effect can also be achieved.
[0043] Specifically, the included angle between the orientation of the second fire hole 121 and the horizontal plane is in the range of 25°-65°. For example, it can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60° or 65°. The specific angle can be designed according to the actual situation.
[0044] In the present embodiment, at least two rings of fire holes are respectively arranged on the outer ring fire cover 110 and the inner ring fire cover 120, each ring of fire holes includes a plurality of fire holes, and the plurality of fire holes are uniformly distributed along the circumferential direction at equal intervals. The uniform distribution structure is beneficial to the uniformity of the fire. The first fire hole 111 and the second fire hole 121 can be, but are not limited to, circular holes. Of course, the shape of the first fire hole 111 and the second fire hole 121 is not limited to circular, but can also be rectangular, elliptical or other shapes, which will not be listed one by one here.
[0045] Specifically, at least two rings of first fire holes 111 are arranged on the inner ring surface of the outer ring fire cover 110 at intervals along the height direction.

It should be noted that the number of fire holes included in each ring of fire holes is not specifically limited in the present embodiment, and can be designed according to the actual situation.
[0046] In terms of spatial position relationship, the lowermost ring of first fire holes 111 is higher than the uppermost ring of second fire holes 121. That is, all the first fire holes 111 are located above the second fire holes 121. This structure can ensure that the upper and lower two parts of the flame jointly form a relatively flat flame surface.
[0047] In order to improve the flame intensity and further improve the combustion heat efficiency, the first fire holes 111 of two adjacent circles at different heights are arranged in a staggered manner in the circumferential direction. The second fire holes 121 of two adjacent circles at different heights are arranged in a staggered manner in the circumferential direction.
