[0056] The guide structure 3 is connected to a side of the upper base 2 close to the second air inlet 20 and includes a guide block 31 . The side of the guide block 31 close to the second air inlet 20 is inclined upward.

[0057] Among them, there are multiple second air inlet holes 20, which are evenly distributed at the bottom of the upper base 2. After passing through the first air inlet hole 10, the gas is diverted by the second air inlet hole 20. The guide block 31 uses an inclined surface that tilts upward from inside to outside to make the gas quickly and evenly distributed to the top of the ignition device, so that the fire is uniform and the generation of smoke is reduced.

[0058] The present application sets up the lower base 1 and the upper base 2 to insulate the gas, especially the air channel corresponding to the upper base 2, which can Figure 3-6 The outer ring fire shown in the figure forms an insulation layer to reduce heat dissipation and improve thermal efficiency.

[0059] In a preferred embodiment of the present invention, the upper base 2 includes an upper base body 21 and a cylinder 22, an upper base through hole is opened at the bottom of the upper base body 21, and the cylinder 22 is sleeved on the inner periphery of the upper base through hole, wherein the second air inlet 20 is distributed on the outer periphery of the upper base through hole.

[0060] In a preferred embodiment of the present invention, the lower base 1 includes a lower base body 11, a support tube 12 and a connecting plate 13.

When assembling the lower base 1 and upper base 2, the cylinder 22 is inserted into the lower base through-hole and secured to the bottom periphery of the support cylinder 12, securing the lower base 1 and upper base 2.

[0062] In the present application, the bottom of the lower base body 11 and the bottom of the support tube 12 are in two different planes, so that the connecting plate 13 extends upward from the support tube 12 toward the lower base body 11, so that there is no contact between the base of the upper base body 21 and the connecting plate 13, avoiding the heat from the bottom of the upper base body 21 to be transferred to the connecting plate 13, achieving thermal insulation of the gas and reducing heat loss.

[0063] The second air inlet 20 is located above the first air inlet 10 and can divert the gas.

[0064] In a preferred embodiment of the present invention, the support tube 12 is a stepped tube, which includes a first step 121 located at the lower portion of the stepped tube. The first step 121 is provided with a plurality of third air inlet holes 1210 .

[0065] like Figure 2 、 4 and 5, the support tube 12 is a stepped tube, which has at least two steps, wherein the first step 121 is located at the lower part of the stepped tube, and the second step, the third step tube, and so on are arranged from bottom to top.

A second groove 211 corresponding to the first groove 111 is formed upward on the bottom of the upper base body 21, and an upper base through hole is provided at the bottom of the second groove 211, wherein the second groove 211 is sleeved on the outer periphery of the first groove 111.

[0069] like Figure 1 As shown, the first groove 111 is provided to facilitate the quick installation of the lower base 1 on the burner 4, and the second groove 211 is sleeved on the outer periphery of the first groove 111. The middle of the bottom of the second groove 211 and the first groove 111 is aligned with the middle of the burner 4, which facilitates centering and also facilitates the processing of the ignition divider 3.

[0070] In a preferred embodiment of the present invention, the guide block 31 is provided with a first air guide hole 32 and a second air guide hole 33.

The inner side is tilted upward and outward from the bottom of the upper base body 21, which can guide the gas. In addition, there are multiple first air guide holes 32, which are evenly spaced along the guide block 31. The first air guide holes 32 can increase the air outlet area, make the airflow more stable, and reduce the smoke. In particular, the second air guide holes 33 on the outer side of the guide block 31 can quickly guide the gas transported by the first air inlet 10 to the periphery, so that the gas is quickly and evenly distributed to the top air outlet end of the ignition divider. This solves the problem that the size of the combustion plate must be larger than the size of the burner 4, and that a large gas flow rate is required for stir-frying, resulting in uneven air outlet. Therefore, the present application can guide the gas to the outside through the guide block 31, the first air guide hole 32, and the second air guide hole 33, thereby improving combustion efficiency.

[0071] In a preferred embodiment of the present invention, there are multiple guide blocks 31, and the multiple guide blocks 31 are evenly distributed along the bottom of the upper base body 21, which can evenly guide the gas to the periphery of the ignition distributor.

[0075] like Figure 5-6 As shown, the second air inlet 20 is a grid hole to divert the gas, and a portion of the second air inlet 20 is covered by a cover plate 23. The cover plate 23 is conducive to reflecting heat. When 1 / 5≤a / b≤1 / 2, while ensuring the air outlet area, heat reflection is increased to improve thermal efficiency.

[0076] The cover plate 23 includes two vertical plate segments perpendicular to the upper air guide plate 323 and a connecting plate segment. The connecting plate segment connects the two vertical plate segments. The vertical plate segments are triangular or fan-shaped, while the connecting plate segment is rectangular or arc-shaped. One end of the connecting plate segment is connected to the upper base body 21, and the other end is located above the upper base body 21. The other end of the connecting plate segment and the two vertical plate segments form an outlet to facilitate air outlet and increase heat reflection. In this application, the air is discharged through the bottom and side walls of the cover plate 23.
