Technical Field
[0001] The utility model relates to the technical field of burners, and particularly relates to an inner ring burner head and a burner comprising the same. Background Art
[0002] The ignition needle of a burner is usually arranged close to the inner ring burner head. In the existing inner ring burner head, ignition holes are arranged corresponding to the ignition needle. However, it is found in use that the burner still has problems such as difficult ignition and low ignition success rate. Therefore, an inner ring burner head is needed to solve the above problems. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the defects of difficult ignition and low ignition success rate of the existing burner, and to provide an inner ring burner head and a burner comprising the same.
[0004] The utility model solves the above technical problem by the following technical scheme:
[0005] An inner ring burner head, the inner ring burner head comprising:
[0006] A truncated plane, the truncated plane is arranged at the edge of the inner ring burner head, and the truncated plane extends along the height direction of the inner ring burner head;
[0007] Ignition holes, a plurality of ignition holes are provided, and the plurality of ignition holes are located on the truncated plane. The ignition holes penetrate through the truncated plane and are communicated with the gas channel of the inner ring burner head. The plurality of ignition holes are arranged in a "pin" shape, and the plurality of ignition holes are all arranged corresponding to the ignition needle.
[0008] In this solution, by providing a truncated plane and arranging a plurality of ignition holes on the truncated plane, the gas flowing through the ignition holes to the ignition needle flows out simultaneously and at the same flow rate when flowing out of the inner ring burner head, ensuring sufficient gas volume on the outer peripheral side of the ignition needle, thereby improving the ignition success rate. In addition, the ignition success rate can also be improved by increasing the number of ignition holes, so that the ignition needle can achieve successful ignition when a certain ignition hole is ignited. The plurality of ignition holes arranged in a "pin" shape can make the gas fill all positions at the end of the ignition needle. When a certain ignition hole is ignited, the remaining ignition holes provide a flame stabilizing function when being ignited, reducing the ignition difficulty and preventing accidental flameout in the case of setting a single ignition hole.
[0009] Preferably, the number of the ignition holes near the top of the inner ring burner head is less than the number of the ignition holes far from the top of the inner ring burner head.
[0010] In this solution, through the above setting, a larger number of ignition holes are arranged corresponding to the end of the ignition needle to ensure sufficient gas volume at the end of the ignition needle.
[0011] Preferably, the inner ring burner cap further includes a blockage prevention channel, which communicates with the ignition holes near the top of the inner ring burner cap, extends into the gas channel, and is provided with a plurality of communication holes along the height direction of the inner ring burner cap downward.
[0012] In this solution, through the above settings, when the ignition holes are affected by the overflow of the cookware, the overflow liquid flows into the gas channel through the ignition holes, the blockage prevention channel and the communication holes, thereby preventing the channel for the gas to flow to the ignition holes from being blocked and affecting ignition failure. The arrangement of the plurality of communication holes enables the overflow liquid to still be discharged through other communication holes in the case where a certain communication hole is blocked.
[0013] Preferably, the blockage prevention channel extends horizontally and penetrates through the inner ring burner cap.
[0014] In this solution, through the above settings, to further improve the ability of the blockage prevention channel to prevent blockage by overflow liquid, the overflow liquid can directly flow out from the penetration.
[0015] Preferably, the inner ring burner cap includes a brim, which is arranged at the top of the inner ring burner cap, and a protrusion is arranged in the area corresponding to the ignition holes on the brim.
[0016] In this solution, by setting the protrusion, the ignition holes and the ignition needle are shielded along the direction of the overflow of the cookware to prevent accidental flameout.
[0017] Preferably, a retaining edge is arranged at one end of the protrusion away from the outer surface of the inner ring burner cap, the retaining edge is arranged corresponding to the ignition holes, and the retaining edge extends towards the ignition needle along the height direction of the inner ring burner cap.
[0018] In this solution, by setting the retaining edge, the gas flowing out of the ignition holes is blocked, so that the gas flow rate is reduced and accumulates between the retaining edge and the ignition holes, and the gas concentration on the outer periphery of the ignition needle is increased.
[0019] Preferably, a boss is further arranged on the protrusion, the boss is arranged corresponding to the ignition needle, and the boss is located between the retaining edge and the outer surface of the inner ring burner cap.
[0020] In this solution, by setting the boss, a breakdown voltage can be generated faster when the ignition needle ignites, and the ignition response efficiency is improved.
[0021] Preferably, the inner ring burner cap is further provided with a first flame stabilizing groove and a second flame stabilizing groove, and the first flame stabilizing groove and the second flame stabilizing groove are sequentially arranged below the ignition holes along the height direction of the inner ring burner cap.
[0022] In this solution, the first flame-stabilizing groove and the second flame-stabilizing groove are provided to improve the flame-stabilizing ability of the inner ring burner cap.
[0023] Preferably, the first flame-stabilizing groove is arranged horizontally and communicated with the gas passage. The second flame-stabilizing groove includes a first section and a second section that are sequentially communicated. The first section is arranged horizontally and penetrates the outer surface of the inner ring burner cap. The second section is arranged between the first section and the gas passage and communicated with the gas passage. The second section is inclined outward from the flowing direction of the gas passage.
[0024] In this solution, by arranging the first section and the second section in the second flame-stabilizing groove, the ability of the second flame-stabilizing groove to prevent liquid overflow and blockage, that is, the anti-blocking ability, is improved.

[0026] In this solution, the burner includes the above-mentioned inner ring burner cap, so as to improve the ignition success rate of the burner and reduce the ignition difficulty.
[0027] The positive and progressive effects of the present utility model are as follows: by providing a cutting plane and arranging a plurality of ignition holes on the cutting plane, the gas flowing through the ignition holes to the ignition needle flows out simultaneously and at the same flow rate when flowing out of the inner ring burner cap, ensuring sufficient gas volume on the outer peripheral side of the ignition needle, thereby improving the ignition success rate. In addition, the ignition success rate can also be improved by increasing the number of ignition holes, so that the ignition needle can achieve successful ignition when igniting a certain ignition hole. The distribution of multiple ignition holes in a "pin" shape can make the gas fill all positions at the end of the ignition needle. When a certain ignition hole is ignited, the remaining ignition holes provide a flame-stabilizing function when being ignited, reducing the ignition difficulty and preventing accidental flameout in the case of setting a single ignition hole.

[0045] The following is a preferred embodiment and is described in more clearly and completely in conjunction with the accompanying drawings for the present utility model.
[0046] This embodiment provides an inner-ring burner head, and the specific structure is as Figure 1 , Figure 2 and Figure 3 shown. The inner-ring burner head includes:
[0047] Cutting plane 1, the cutting plane 1 is arranged at the edge of the inner-ring burner head, and the cutting plane 1 extends along the height direction of the inner-ring burner head;
[0048] Ignition hole 2, there are multiple ignition holes 2, the multiple ignition holes 2 are located on the cutting plane 1, the ignition holes 2 penetrate the cutting plane 1 and are communicated with the gas channel of the inner-ring burner head, the multiple ignition holes 2 are arranged in a "pin" shape, and the multiple ignition holes 2 are correspondingly arranged with the ignition needle (not shown in the figure).
[0049] Specifically, the inner ring burner cap is of a cylindrical structure, and a plurality of ignition holes are provided on the side of the inner ring burner cap. A cover body is provided on the top of the inner ring burner cap to seal the gas passage of the inner ring burner cap. The plurality of ignition holes are communicated with the gas passage so that they can be ignited by the ignition hole 2 when the ignition hole 2 is ignited by the ignition needle. This is the prior art and will not be elaborated here. It should be noted that the cut plane 1 is flush with itself. When the cut plane 1 intersects the cylindrical inner ring burner cap in the height direction, a plane is formed at the edge of the inner ring burner cap, and the plurality of ignition holes 2 are provided on the cut plane 1 so that the gas outlet ends of the plurality of ignition holes 2 are flush with each other in the horizontal direction, so that the gas flowing through the ignition hole 2 to the ignition needle flows out of the inner ring burner cap simultaneously and at the same flow rate, ensuring that there is sufficient gas on the outer peripheral side of the ignition needle, thereby improving the ignition success rate. By increasing the number of ignition holes 2 to improve the ignition success rate, the ignition needle can achieve successful ignition when igniting a certain ignition hole 2. In the case where the gas outlet ends are flush, the gas flow rates are the same, and it is easier for the gas to accumulate on the outer peripheral side of the ignition needle.
[0050] It can be understood that compared with the "one" - shaped distribution of the plurality of ignition holes 2, the "pin" - shaped distribution of the plurality of ignition holes 2 on the cut plane 1 can make the gas fill each position at the end of the ignition needle. And when a certain ignition hole 2 is ignited, the plurality of ignition holes 2 distributed in a "pin" - shaped pattern can provide a flame - stabilizing function when the remaining ignition holes 2 are ignited, reducing the ignition difficulty and preventing accidental flameout in the case of setting a single ignition hole 2. In this embodiment, the number of the plurality of ignition holes 2 is at least three to meet the "pin" - shaped distribution. In other embodiments, the number of the ignition holes 2 can also be greater than three, such as six, as long as the "pin" - shaped distribution is satisfied.
[0051] Further, the number of ignition holes 2 at the top of the inner ring burner cap is less than the number of ignition holes 2 away from the top of the inner ring burner cap. Taking the number of ignition holes 2 being three as an example, among the three ignition holes 2 distributed in a "pin" - shaped pattern, one ignition hole 2 is arranged close to the top of the inner ring burner cap, and the remaining two ignition holes 2 are arranged away from the top of the inner ring burner cap, so as to arrange a larger number of ignition holes 2 corresponding to the end of the ignition needle to ensure sufficient gas at the end of the ignition needle.
[0052] In this embodiment, the inner ring burner cap further includes an anti - blockage channel 3. The anti - blockage channel 3 is communicated with the ignition hole 2 close to the top of the inner ring burner cap. The anti - blockage channel 3 extends into the gas passage, and a plurality of communication holes 31 are opened downward along the height direction of the inner ring burner cap.
[0053] Specifically, the anti-blocking channel 3 is arranged in the gas channel and at least one ignition hole 2 communicates with the anti-blocking channel 3. In this embodiment, the ignition hole 2 near the top of the inner ring burner cap is taken as an example to illustrate the anti-blocking channel 3. A plurality of communication holes 31 are arranged on the anti-blocking channel 3, and the communication holes 31 extend downward in the height direction of the inner ring burner cap, so that when the ignition hole 2 is affected by the overflow of the cookware, the overflow liquid flows into the gas channel through the ignition hole 2, the anti-blocking channel 3 and the communication holes 31, thereby preventing the channel for the gas to flow to the ignition hole 2 from being blocked and causing ignition failure.
[0054] In this embodiment, the number of the communication holes 31 is two. In other embodiments, the number of the communication holes 31 can also be three or more. The arrangement of the plurality of communication holes 31 enables the overflow liquid to still be discharged through other communication holes 31 in the case where a certain communication hole 31 is blocked, ensuring that the anti-blocking channel 3 is unblocked and the gas in the gas channel can smoothly flow into the ignition hole 2 from the anti-blocking channel 3.
[0055] Furthermore, the anti-blocking channel 3 extends in the horizontal direction and penetrates the inner ring burner cap.
[0056] Specifically, the anti-blocking channel 3 extends from the inner wall of the gas channel close to the section plane 1 to the opposite inner wall of the gas channel, and penetrates the inner wall of the inner ring burner cap far from the section plane 1. That is to say, both ends of the anti-blocking channel can receive and discharge the overflow liquid. By increasing the outflow path of the overflow liquid, the anti-overflow liquid blocking ability of the anti-blocking channel 3 is further improved, and the overflow liquid can directly flow out from the penetration. And the situation where the communication holes 31 are blocked is reduced.
[0057] In addition, the horizontally arranged anti-blocking channel 3 can prevent the overflow liquid from accumulating in the anti-blocking channel 3, so as to improve the smoothness of the anti-blocking channel 3.
[0058] In this embodiment, the inner ring burner cap includes a brim 4, the brim 4 is arranged at the top of the inner ring burner cap, and a protruding part 41 is arranged at the brim 4 corresponding to the area where the ignition hole 2 is located.
[0059] It can be understood that the size of the brim 4 is larger than the diameter of the inner ring burner cap. This is the prior art and will not be elaborated here. And the size of the protruding part 41 is larger than the edge size of the other brim 4. The protruding part 41 extends horizontally towards the area where the ignition hole 2 and the ignition pin are located, so as to block the overflow liquid from dripping onto the ignition hole 2 and the ignition pin when the cookware overflows, preventing accidental flameout.
[0060] At the same time, in this embodiment, a baffle 411 is arranged at one end of the protruding part 41 far from the outer surface of the inner ring burner cap. The baffle 411 is arranged corresponding to the ignition hole 2, and the baffle 411 extends towards the ignition pin in the height direction of the inner ring burner cap.
[0061] Specifically, the retaining eaves 411 are made of a plate material and integrally formed with the protruding portion 41. The retaining eaves 411 extend downward along the height direction of the inner ring burner cap, and the ignition needle is located between the retaining eaves 411 and the ignition hole 2 to block the gas flowing out of the ignition hole 2, reducing the gas flow rate and accumulating the gas between the retaining eaves 411 and the ignition hole 2, that is, accumulating the gas on the outer peripheral side of the ignition needle, increasing the gas concentration on the outer peripheral side of the ignition needle, and thus improving the ignition success rate.
[0062] In this embodiment, a boss 412 is further provided on the protruding portion 41. The boss 412 is arranged corresponding to the ignition needle and is located between the retaining eaves 411 and the outer surface of the inner ring burner cap.
[0063] Specifically, the boss 412 is of a cylindrical structure or a conical structure and extends toward the end of the ignition needle, reducing the distance between the ignition end of the ignition needle and the brim 4, thereby reducing the time required for the ignition needle to discharge, enabling the ignition needle to generate a breakdown voltage faster when igniting, and improving the ignition response efficiency.
[0064] As Figure 4 shown, in this embodiment, the inner ring burner cap is further provided with a first flame stabilizing groove 5 and a second flame stabilizing groove 6. The first flame stabilizing groove 5 and the second flame stabilizing groove 6 are sequentially arranged below the ignition hole 2 along the height direction of the inner ring burner cap.
[0065] Specifically, the first flame stabilizing groove 5 is located below the ignition hole 2, and the second flame stabilizing groove 6 is located below the first flame stabilizing groove 5. Both the first flame stabilizing groove 5 and the second flame stabilizing groove 6 are communicated with the gas passage of the inner ring burner cap so as to be ignited by the ignition hole 2 when the ignition hole 2 is ignited. It can be understood that at least part of the first flame stabilizing groove 5 and the second flame stabilizing groove 6 is located below the projection direction of the protruding portion 41 to improve the flame stabilizing ability of the inner ring burner cap through the shielding of the protruding portion 41. By increasing the number of flame stabilizing grooves, compared with a single flame stabilizing groove, its fire retention and flame stabilizing ability is stronger.
[0066] In this embodiment, the first flame stabilizing groove 5 is arranged horizontally and communicated with the gas passage. The second flame stabilizing groove 6 includes a first section 61 and a second section 62 that are sequentially communicated. The first section 61 is arranged horizontally and penetrates the outer surface of the inner ring burner cap. The second section 62 is arranged between the first section 61 and the gas passage and is communicated with the gas passage. The second section 62 is inclined outward from the flowing direction of the gas passage.
[0067] Specifically, the first flame stabilizing groove 5 is arranged below the anti-blocking passage 3. Multiple flame stabilizing holes may be arranged in the first flame stabilizing groove 5, or the first flame stabilizing groove 5 is only a rectangular cut groove, so as to ignite the first flame stabilizing groove 5 through the ignition hole 2 and retain the flame through the first flame stabilizing groove 5 when the ignition hole 2 is blocked by overflow liquid and goes out, that is, the function of flame stabilizing and fire retention.
[0068] Further, the second flame stabilizing groove 6 is arranged below the first flame stabilizing groove 5. The second flame stabilizing groove 6 includes a first section 61 arranged in the horizontal direction. The first section 61 is used to penetrate the outer surface of the inner ring burner cap towards the ignition pin. The second section 62 is arranged to incline outwards in the flowing direction of the gas passage. When the overflow liquid blocks the first flame stabilizing groove 5 and the first section 61, the inclined second section 62 is used to divert the overflow liquid into the gas passage, thereby preventing the second flame stabilizing groove 6 from being blocked, ensuring the ability of the second flame stabilizing groove 6 to prevent overflow liquid from being blocked, that is, the anti-blocking ability, and further retaining the flame through the second flame stabilizing groove 6 to prevent accidental flameout.
[0069] This embodiment also provides a burner, which includes the above-mentioned inner ring burner cap.
[0070] Specifically, the burner is provided with an inner ring burner cap and an ignition pin. The inner ring burner cap includes a truncated plane 1, a plurality of ignition holes distributed in a "pin" shape, a retaining edge 411, and a first flame stabilizing groove 5 and a second flame stabilizing groove 6. When the burner is ignited, the corresponding time is shorter, the ignition efficiency is higher, the ignition success rate is correspondingly improved, the ignition difficulty of the burner is reduced, and the actual use experience of users is improved.
[0071] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only an example. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
