[0035] See attached Figure 1 Figure 5 Figure 6a , Figure 6b and Figure 7This embodiment describes a burner suitable for home kitchen stoves, specifically a burner assembly of a burner. The burner assembly is composed of an anti-dry burning probe 1, a heat insulation sheet 2, an inner ring fire cover 3, an outer ring fire cover 4, a burner body 5, and a stove frame 6, which are assembled in sequence. In order to minimize the gas consumption ratio of the burner and improve the calorific value effect of the burner in a dynamic state, this embodiment emphasizes the design of a secondary air channel 51, an outer ring air climbing channel 52, an inner ring air and gas mixing channel 53, a 360° epoxy filler 54, a suspension limit ring 55, an air guide ring 56, a crescent nozzle protection cover 57, and a bell-mouth ejector tube 58 on the burner body 5; therefore, the secondary air channel in the embodiment is arranged between the outer ring air climbing channel and the inner ring air and gas mixing channel, The 360° epoxy resin is arranged at the outer edge of the burner body, and its circumference is smaller than that of the burner body; and the air guide ring is arranged on an outer side of the burner body, and its circumference is equal to that of the 360° epoxy resin; in practice, the burner body 5 in this example is arranged on the furnace frame 6; such a design realizes a compact layout of the burner body, and at the same time ensures sufficient mixed oxygen between the burner assembly and the burner, and the thermal effect of the burner reaches an optimal level.

[0036] See also Figure 2 The contribution of this embodiment is also reflected in the structural design of the anti-dry burning probe 1, the heat insulation sheet 2, the inner ring fire cover 3, the outer ring fire cover 4, the stove head body 5, and the stove frame 6. For example, the anti-dry burning probe 1 is composed of a probe 11 with a thermistor, a probe rod 12, a probe fixing bolt 13, and a probe anti-slip tenon riveted workpiece 14. When there is no one on duty, in order to prevent the pot on the stove from drying out, once the thermistor installed in the probe 11 (not shown) senses that the temperature of the pot bottom reaches 270°C, the probe rod 12 automatically extends and drives the heat insulation sheet 2 to block heat from the pot bottom; in a static state, the anti-dry burning probe is vertically arranged in the stove head body, and the probe is flush with the heat insulation sheet.

[0037] See also Figure 3a , Figure 3b The embodiment is about the heat insulation sheet 2 in the stove head assembly. In practice, four outer ring baffles 21 and four limit plates 22 are arranged on the main body, and a hollow heat dissipation port 23 is arranged between every two outer ring baffles on the heat insulation sheet main body; the heat insulation sheet main body is arranged on the inner ring fire cover 3; in practice, the function of the heat insulation sheet is to cooperate with the anti-dry burning function of the anti-dry burning probe, and the limit plate 22 is limited to the height between it and the fire cover. When the anti-dry burning probe is activated, the outer ring baffle blocks the fire hole on the fire cover, and the heat insulation sheet isolates the heat of the fire cover, and the heat of the fire cover is dissipated from the hollow heat dissipation port, thereby ensuring that the bottom of the pot is not dry burned.

[0038] See also Figure 4a , Figure 4bThe embodiment describes an inner ring fire cover 3 in a burner assembly, on which a heat insulation plate limiting step 31, a fire stabilizing groove 32, a fire hole 33, an anti-overflow cap 34, an assembly step 35 and a fire stabilizing hole 36 are provided; in practice, the fire stabilizing groove matches the angle of the fire hole, which can effectively prevent flying fire and flame separation when the burner is burning; the anti-overflow cap can prevent the soup from bursting into the pot without fire; the heat insulation plate limiting step and the assembly step are both specific workstations specially designed for use with the heat insulation plate and enable the fire cover body to accurately fall onto the outer ring fire cover.

[0039] See also Figure 5a , Figure 5b The embodiment describes an outer ring fire cover 4 in a burner head assembly, on which a fire cover body is provided with an ignition groove 41, a fire hole 42, a fire stabilizing hole 43, an assembly step 44, an anti-overflow cap 45, and a fire stabilizing groove 46; the functions of these functional components are similar to those of the components on the inner ring fire cover, and will not be described in detail in this example; in practice, the fire cover body is directly arranged on the burner head body.

[0040] See also Figure 6a , Figure 6b The embodiment describes that the bell-mouthed ejector pipe 58 is respectively connected to an outer ring air climbing channel 52. After the gas and air are mixed once, they enter the outer ring air climbing channel 52 through the bell-mouthed ejector pipe 58. At this time, due to the wavy structure inside the outer ring air climbing channel 52, the mixed gas flows in a ring shape and fluctuates continuously along the wavy structure, which is conducive to fully mixing the gas and air, thereby improving the combustion effect of the mixed gas.

[0041] In summary, the present invention has detailed the structural characteristics of the burner head assembly of the burner by means of an expanded diagram and an explanation of an embodiment. In reality, from the perspective of mass production of products, the above technical solutions can provide a truly beneficial reference and reference for the establishment of industry standards.
