[0043] The utility model will be described below with a preferred embodiment and in combination with the drawings.

[0044] As Figs. 1-2As shown, the embodiment provides an inner igniter 001, which includes an igniter body 1 and a plurality of ignition pipes 2, the ignition pipes 2 are located above the top surface of the igniter body 1, the pipe ends of the ignition pipes 2 are respectively arranged on the side surface of the igniter body 1 and respectively communicate with the gas chamber (not shown in the figure) inside the igniter body 1, a plurality of ignition ports 201 are arranged on the surface of each ignition pipe 2, the ignition pipes 2 are intersected above the top surface of the igniter body 1, and the secondary air flow gaps 3 communicating to the top surface of the igniter body 1 are formed between adjacent two ignition pipes 2, and a plurality of auxiliary heating fire holes 101 are arranged on the igniter body 1, which communicate to the gas chamber inside the igniter body 1, and the auxiliary heating fire holes 101 are arranged close to the pipe ends of the ignition pipes 2.

[0045] By arranging a plurality of ignition pipes 2 above the top surface of the inner igniter 001, the ignition pipes 2 communicate with the gas chamber inside the igniter body 1, the ignition ports 201 are arranged on each ignition pipe 2, and the ignition pipes 2 are intersected above the top surface of the igniter body 1, the gas flows from the gas chamber inside the igniter body 1 into the ignition pipes 2, and flows along the ignition pipes 2 to above the top surface of the igniter body 1, and flows out through the ignition ports 201, and is dispersed above the top surface of the igniter body 1, so that the gas burns in the range near the center of the top of the inner igniter 001, and when the pot is arranged on the burner, the bottom of the pot is heated more evenly.

[0046] At the same time, the secondary air flow gaps 3 communicating to the top surface of the igniter body 1 are formed between adjacent two ignition pipes 2, and the gas flowing in each ignition pipe 2 can be fully mixed with the secondary air, which improves the combustion efficiency and solves the problem of off-flame. Arranging the pipe ends of the ignition pipes 2 on the side surface of the igniter body 1 can increase the coverage area of the ignition pipes 2, so that the edge of the pot bottom can also be heated, and further increase the uniformity of the heating of the pot bottom. The auxiliary heating fire holes 101 arranged on the igniter body 1 close to the pipe ends of the ignition pipes 2 can preheat the gas passing through the ignition pipes 2, so that the gas temperature reaches the ignition point faster, accelerates the combustion of the gas, and the flame is more stable, avoiding off-flame.

[0047] Specifically, in the embodiment, as shown in the figure, Fig. 1 that is, the pipe end part of the ignition pipe 2 connected with the igniter body 1 is perpendicular to the side surface of the igniter body 1, when the gas flows from the gas chamber inside the igniter body 1 into the ignition pipe 2, the gas flows vertically to the side wall of the igniter body 1 and smoothly enters the ignition pipe 2, so that the gas flow resistance is smaller and the gas flows more smoothly.

[0048] Meanwhile, in the present embodiment, the pilot conduit 2 is curved in an obliquely upward direction from the side surface of the pilot body 1. By curving the pilot conduit 2 in the obliquely upward direction from the side surface of the pilot body 1, the pilot conduit 2 does not need to extend too much in the radially outward direction of the inner pilot 001, the path of the gas flow to above the top surface of the pilot body 1 is shortened, and the radial dimension of the entire inner pilot 001 can be controlled not to be too large.

[0049] Of course, in other embodiments, the pilot conduit 2 can also extend outward in a direction perpendicular to the side surface of the pilot body 1 for a distance before being curved obliquely upward, so as to increase the projection area of the pilot conduit 2 in the vertical direction, thereby widening the area of the combustion region.

[0050] In the present embodiment, as shown in Fig. 2 , the setting position of the outlet port 201 on the pilot conduit 2 is at least located outside the projection area of the top surface of the pilot body 1 in the vertical direction. By this structural setting scheme, the heating area of the outlet port 201 is improved.

[0051] In the present embodiment, the number of auxiliary heating ports 101 is equal to the number of conduit end portions of the pilot conduit 2, and the auxiliary heating ports 101 are arranged between two adjacent conduit end portions of the pilot conduit 2. That is, the auxiliary heating ports 101 in the present embodiment are arranged on the side surface of the pilot body 1, so that the auxiliary heating ports 101 are closer to the conduit end portions of the pilot conduit 2, so that the gas can be preheated before flowing out through the outlet port 201. Each auxiliary heating port 101 can heat the conduit end portions of the two adjacent pilot conduits 2, and each conduit end portion can also be heated by the two adjacent auxiliary heating ports 101, so that the heating of the conduit end portions is more uniform.

[0052] Of course, in other embodiments, the number of auxiliary heating ports 101 can also be 3 times or more than the number of pilot conduits 2. Setting the number of auxiliary heating ports 101 to be a multiple of the number of pilot conduits 2 can enable each conduit to correspond to the same number of auxiliary heating ports 101, so that the preheating of the pilot conduits 2 is more uniform. Meanwhile, the positions of the auxiliary heating ports 101 can also be arranged on the top surface of the pilot body 1, and / or the auxiliary heating ports 101 can be arranged directly below the pilot conduits 2, or the auxiliary heating ports 101 can be arranged on both the top surface and the side surface of the pilot body 1, which will not be described here.

[0053] Meanwhile, in the present embodiment, as shown in Fig. 1 and Fig. 2As shown, the projection of the ignition pipe 2 in the vertical direction extends along the radial direction of the inner igniter 001, and the intersection positions of the plurality of ignition pipes 2 are located on the axis of the inner igniter 001, the distance from the axis to the communication position with the igniter body 1 is equal for each ignition pipe 2, and the ignition pipes 2 can be symmetrically arranged with the axis of the inner igniter 001 as the center. By arranging the intersection positions of the ignition pipes 2 on the axis of the inner igniter 001, the uniformity of the combustion gas in the ignition pipe 2 can be improved, and the entire inner igniter 001 is more beautiful.

[0054] Of course, in other embodiments, as long as the plurality of pipes intersect at the top surface of the igniter body 1, the intersection positions can be arbitrarily selected, and basically the uniformity of the combustion gas can be ensured to be relatively uniform above the top surface of the igniter body 1, but the closer the intersection position is to the axis of the inner igniter 001, the higher the uniformity of the combustion gas, and the more beautiful the entire inner igniter 001.

[0055] In the embodiment, as shown in the figure, Fig. 2 the number of ignition pipes 2 is 5, and the plurality of ignition pipes 2 are uniformly distributed along the circumferential direction of the inner igniter 001. By arranging 5 ignition pipes 2, the density of the ignition pipes 2 is ensured, and the 5 ignition pipes 2 are uniformly distributed along the circumferential direction of the inner igniter 001, ensuring the uniformity of the ignition pipes 2, thereby ensuring the uniform distribution of the combustion gas above the top surface of the igniter body 1 and the sufficient concentration.

[0056] Of course, in other embodiments, the number of ignition pipes 2 can also be greater than 5, and the more the number of ignition pipes 2, the greater the density of the ignition pipes 2 above the top surface of the igniter body 1, and the more uniform the distribution of the combustion gas, but the number of ignition pipes 2 should not be too large. When the number of ignition pipes 2 is equal to 10, increasing the number of ignition pipes 2 does not greatly improve the uniformity of the distribution of the combustion gas, and increases the manufacturing cost, which will not be described here.

[0057] In the embodiment, as shown in the figure, Fig. 2 the specific form of the fire outlet 201 is a plurality of fire holes distributed along the axial direction of the ignition pipe 2, and specifically, the number of fire holes on each ignition pipe 2 in the embodiment is 3. By arranging 3 fire holes on each ignition pipe 2, the distribution density of the fire holes in the axial direction of the ignition pipe 2 is high, which can meet the requirement of the concentration of the combustion gas and make the combustion gas more uniform.

[0058] At the same time, along the radial direction outward of the inner igniter 001, the hole diameter of the fire hole gradually increases. Since along the radial direction outward of the inner igniter 001, the area covered by the fire hole will gradually increase, therefore, arranging the fire hole to gradually increase along the radial direction outward can further improve the uniformity of the distribution of the combustion gas.

[0059] Of course, in other embodiments, the form of the fire outlet 201 can also be a fire slot, that is, an axially extending fire slot is arranged on the fire distribution pipe 2, and the specific fire slot can be a relatively long strip-shaped slot extending to the axis of the inner burner 001, or a plurality of relatively short strip-shaped slots distributed along the axial direction of the fire distribution pipe 2, which will not be repeated here. By arranging the fire slot to extend to the axis of the inner burner 001, the center of the top of the inner burner 001 also has gas spouting, and in turn the center of the pot has flame burning, so that the pot is heated more evenly.

[0060] In the embodiment, the wall thickness of the fire distribution pipe 2 is equal to 1mm. By arranging the wall thickness of the fire distribution pipe 2 to be 1mm, the structural strength of the fire distribution pipe 2 is ensured.

[0061] Of course, in other embodiments, the wall thickness of the fire distribution pipe 2 can also be thicker, that is, the wall thickness of the fire distribution pipe 2 can be greater than 1mm, so as to increase the structural strength of the fire distribution pipe 2.

[0062] In the embodiment, a burner is also provided, which comprises the above-mentioned inner burner 001. By arranging the above-mentioned inner burner 001 in the burner, the combustion efficiency of the burner can be improved, and the problem of off-flame can be avoided.

[0063] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that this is only an example, the protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the utility model, but these changes and modifications all fall within the protection scope of the utility model.
