Description

Technical Field

[0001] This invention relates to the field of stoves, and particularly to a burner structure and a stove burner. Background Technology

[0002] Existing stove burners consist of an ignition needle and a burner cap structure. The ignition needle is positioned adjacent to and acts on the burner cap structure, generating an electric arc to ignite the gas-air mixture within it. However, existing burner cap structures often only have a single ignition hole; if this hole becomes blocked, ignition will fail. Furthermore, the concentration of gas in the mixture affects the ignition success rate; if a suitable gas concentration is not provided, ignition will also be difficult. Therefore, existing burner cap structures make it difficult to maintain a high ignition success rate. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect that the existing burner cap structure in the prior art often only has one ignition hole, which makes it difficult to maintain a stable and high level of ignition success rate of the stove burner, and to provide a burner cap structure and stove burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A flame cap structure includes a flame cap body and at least one partition. The outer wall of the flame cap structure has an inwardly recessed ignition groove. The partition is disposed in the ignition groove and divides the internal space of the ignition groove into a plurality of ignition chambers for cooperating with an ignition needle.

[0006] The burner cap body has a gas chamber, and the burner cap body has a plurality of ignition holes, all of which are connected to the gas chamber and the ignition slot, and the plurality of ignition holes are respectively connected to the plurality of ignition chambers.

[0007] In this design, the burner cap structure comprises a burner cap body and a separator that work together. The ignition groove formed on the outer wall of the burner cap body is divided into several ignition chambers by the separator. Since the gas chamber within the burner cap body and these ignition chambers are all connected to ignition holes, the gas can reach these chambers through the ignition holes. This allows the ignition chambers to work in conjunction with the ignition needle to achieve ignition, overcoming the limitation of existing technologies where only one ignition hole is blocked, thus ensuring a high ignition success rate. Furthermore, the different gas concentrations within the several ignition chambers further enhance the ignition success rate.

[0008] Preferably, a plurality of ignition chambers are spaced apart along the height direction of the burner cap body, and the internal space of the plurality of ignition chambers is of different sizes, so that different concentrations of gas are formed in the plurality of ignition chambers.

[0009] In this design, several ignition chambers are arranged longitudinally at intervals. Due to the obstruction effect brought about by the structural characteristics of the separator, an internal space can be formed. Therefore, the chambers are arranged at intervals along the height direction of the burner body, and the distance between them is different, forming internal spaces of different sizes. As a result, different concentrations of gas are formed in the several ignition chambers.

[0010] Preferably, the ignition holes in the plurality of ignition chambers have different diameters, so that different concentrations of gas are formed in the plurality of ignition chambers.

[0011] In this scheme, the ignition holes in the ignition chamber have different diameters, so the amount of gas passing through the ignition holes is also different. Since the ignition holes with different diameters are distributed in different ignition chambers, different concentrations of gas are formed in several ignition chambers in the end.

[0012] Preferably, the number of ignition holes in the plurality of ignition chambers is different, so that different concentrations of gas are formed in the plurality of ignition chambers.

[0013] In this design, the number of ignition holes in different ignition chambers is different. Therefore, the gas passing through the ignition holes will eventually converge in the ignition chambers differently, resulting in different concentrations of gas in several ignition chambers.

[0014] Preferably, the several separators have different diameters, and the outer edges of the several separators are all fitted against the inner wall of the ignition slot, and the ignition hole is connected to the ignition chamber so that different concentrations of gas are formed in the ignition chamber.

[0015] In this scheme, because the diameters of the various separators are different, the size of the space formed between the separators at different positions of the burner cap body is also different, resulting in different concentrations of gas in the ignition chamber.

[0016] Preferably, the ignition hole is connected to only one of the several ignition chambers; or, the ignition hole is connected to two adjacent ignition chambers.

[0017] In this design, the ignition hole is connected to one of the ignition chambers, and the concentration is relatively high when connected to one of them; or it is connected to two adjacent ignition chambers, and the concentration is relatively low when connected to both adjacent chambers. Therefore, this technical solution can also form different gas concentrations flowing to the ignition needle to ensure the ignition success rate.

[0018] Preferably, the flame cap body has at least one air hole, which is located at the opening of the ignition slot and is connected to the ignition chamber.

[0019] In this design, the air hole on the burner cap is located at the opening of the ignition slot and is connected to the ignition chamber, so that air can be smoothly introduced into the ignition chamber and come into contact with the gas for combustion.

[0020] Preferably, there are two separators to separate and form three ignition chambers.

[0021] In this solution, the number of separators is set to two, thereby dividing the ignition slot into three ignition chambers. This solution is easy to operate, can quickly achieve the effect of different concentration gradients, and ensures the success rate of ignition.

[0022] A stove burner includes the aforementioned burner cap structure.

[0023] In this design, the stove burner with a flame cap structure can achieve different concentrations within the cavity, thereby forming a gas gradient of different concentrations. Gas of different concentrations flows to the ignition needle, ensuring a high ignition success rate.

[0024] Preferably, the ignition needle has a plurality of ignition parts, and the plurality of ignition parts extend into a plurality of ignition chambers respectively.

[0025] In this design, several ignition parts on the burner cap structure extend into several ignition chambers to ensure full contact with the air and gas in the ignition chambers, thereby improving the ignition success rate.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0027] The positive and progressive effects of this invention are as follows: In this invention, the burner cap structure includes a burner cap body and a separator that cooperate with each other. The ignition groove formed on the outer wall of the burner cap body is divided into several ignition chambers by the separator. Since the gas chamber in the burner cap body and the several ignition chambers are all connected to the ignition holes, the gas can reach the several ignition chambers through the ignition holes, thus enabling the several ignition chambers to cooperate with the ignition needle to achieve ignition. This solves the defect in the prior art where only one ignition hole is blocked and ignition fails, ensuring a high ignition success rate. Furthermore, the different gas concentrations within the several ignition chambers further improve the ignition success rate. Attached Figure Description

[0050] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described herein.

[0051] This invention discloses a flame cap structure 1, as follows: Figure 1 and Figure 2As shown, the burner cap structure 1 includes a burner cap body 2 and at least one partition 3. The outer wall of the burner cap structure 1 has an inwardly recessed ignition groove 4. The partition 3 is disposed in the ignition groove 4 and divides the internal space of the ignition groove 4 into several ignition chambers 41 for cooperating with the ignition needle 8. The burner cap body 2 has a gas chamber 5. Several ignition holes 6 are opened on the burner cap body 2. The several ignition holes 6 are all connected to the gas chamber 5 and the ignition groove 4, and the several ignition holes 6 are respectively connected to the several ignition chambers 41. The burner cap structure 1 comprises a burner cap body 2 and a separator 3 that cooperate with each other. The ignition groove 4 formed on the outer wall of the burner cap body 2 is divided into several ignition chambers 41 by the separator 3. Since the gas chamber 5 in the burner cap body 2 and the several ignition chambers 41 are all connected to the ignition hole 6, the gas can reach the several ignition chambers 41 through the ignition hole 6, so that the several ignition chambers 41 cooperate with the ignition needle 8 to achieve ignition. This solves the defect in the prior art where only one ignition hole 6 is blocked and ignition cannot be successfully achieved, ensuring the ignition success rate. At the same time, the presence of different gas concentrations in the several ignition chambers 41 further improves the ignition success rate.

[0052] Specifically, the burner cap structure 1 is an inner ring burner cap, so its corresponding gas chamber 5 is an inner ring gas chamber, which is connected to the ignition chamber 41 through the ignition hole 6.

[0053] like Figure 2 and Figure 3 As shown, several ignition chambers 41 are spaced apart along the height direction of the burner cap body 2, and the internal space of the several ignition chambers 41 is of different sizes, so that different concentrations of gas are formed in the several ignition chambers 41. The several ignition chambers 41 are arranged longitudinally and spaced apart. Due to the obstruction effect brought about by the structural characteristics of the separator 3, an internal space can be formed. Therefore, the several ignition chambers 41 are spaced apart along the height direction of the burner cap body 2 and the distance between them is different, forming internal spaces of different sizes. Thus, different concentrations of gas are formed in the several ignition chambers 41.

[0054] like Figure 2 and Figure 3 As shown, the ignition holes 6 within several ignition chambers 41 have different aperture sizes, resulting in different concentrations of gas within each ignition chamber 41. Because the aperture sizes of the ignition holes 6 within the ignition chambers 41 are different, the amount of gas passing through the ignition holes 6 is also different. Since the ignition holes 6 with different aperture sizes are distributed in different ignition chambers 41, different concentrations of gas are ultimately formed within the several ignition chambers 41.

[0055] like Figure 2 and Figure 3As shown, the number of ignition holes 6 in the various ignition chambers 41 is different, so that different concentrations of gas are formed in the various ignition chambers 41. Since the number of ignition holes 6 in different ignition chambers 41 is different, the gas passing through the ignition holes 6 will eventually converge in the ignition chambers 41 differently, resulting in different concentrations of gas in the various ignition chambers 41.

[0056] like Figure 3 As shown, several separators 3 have different diameters, and the outer edges of these separators 3 are all fitted against the inner wall of the ignition slot 4. The ignition hole 6 is connected to the ignition chamber 41 to form gas of different concentrations within the ignition chamber 41. Because the diameters of the separators 3 are different, the size of the space formed between the separators 3 at different positions varies depending on the mechanism at different positions of the burner cap body 2, ultimately resulting in gas of different concentrations forming within the ignition chamber 41.

[0057] like Figure 2 and Figure 3 As shown, specifically, in this embodiment of the invention, the separator 3 is divided into an upper separator 31 and a lower separator 32 from top to bottom, and the ignition slot 4 is divided into an upper ignition chamber 411, a middle ignition chamber 412 and a lower ignition chamber 413 from top to bottom, and the space size of the upper ignition chamber 411, the middle ignition chamber 412 and the lower ignition chamber 413 increases sequentially.

[0058] like Figure 2 and Figure 3 As shown, the ignition hole 6 is connected to only one of the several ignition chambers 41; or, the ignition hole 6 is connected to two adjacent ignition chambers 41. When the ignition hole 6 is connected to one of the ignition chambers 41, the concentration is relatively high; or when it is connected to two adjacent ignition chambers 41, the concentration is relatively low. Therefore, this technical solution can also form different gas concentrations flowing to the ignition needle 8, ensuring the ignition success rate.

[0059] like Figure 2 As shown, at least one air hole 7 is provided on the burner cap body 2. The air hole 7 is located at the opening of the ignition groove 4 and is connected to the ignition chamber 41. The air hole 7 on the burner cap body 2 is located at the opening of the ignition groove 4 and is connected to the ignition chamber 41, so air can be smoothly introduced into the ignition chamber 41 and come into contact with the gas for combustion.

[0060] like Figure 2 and Figure 3 As shown, there are two separators 3 to form three ignition chambers 41. By setting the number of separators 3 to two, the ignition slot 4 is divided into three ignition chambers 41. This scheme is easy to operate, can quickly achieve the effect of different concentration gradients, and ensures the success rate of ignition.

[0061] like Figure 2 , Figure 3 and Figure 4 As shown, specifically in this embodiment of the invention, the ignition groove 4 of the inner ring burner cap is shaped like a teardrop. Several ignition holes 6 are distributed along the circumference of the teardrop-shaped ignition groove 4. Air holes 7 are located near the outlet of the teardrop-shaped ignition groove 4, and the rest are ignition holes 6. Two dividing pieces of different diameters are inserted into the teardrop-shaped ignition groove 4, dividing it into an upper ignition chamber 411, a middle ignition chamber 412, and a lower ignition chamber 413. The smaller-diameter dividing piece 3 is inserted between the ignition holes 6 in the upper and lower ignition chambers 41, while the larger-diameter dividing piece 3 is inserted onto the ignition holes 6 in the lower ignition chamber 413, dividing the ignition holes 6 into upper and lower parts.

[0062] The present invention also discloses a stove burner, including the aforementioned burner cap structure 1. The stove burner with burner cap structure 1 can achieve different concentrations within the cavity, thereby forming a gas gradient of different concentrations. Gas of different concentrations flows to the ignition needle 8, ensuring a high ignition success rate.

[0063] like Figure 1 and Figure 2 As shown, the ignition needle 8 has several ignition parts 81, which extend into several ignition chambers 41. The several ignition parts 81 on the burner cap structure 1 all extend into several ignition chambers 41 to ensure sufficient contact with the air and gas in the several ignition chambers 41, thereby improving the ignition success rate.

[0064] Specifically, such as Figure 1 As shown in the embodiment of the present invention, the stove burner also includes an anti-clogging cap 9, which is disposed on the upper part of the burner cap structure 1. The top of the anti-clogging cap 9 has an inwardly recessed liquid accumulation groove 91 for covering the ignition groove 4 and the ignition needle 8.

[0065] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention 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 present invention, but all such changes and modifications fall within the scope of protection of the present invention.
