Description

Technical Field

[0001] The invention relates to a stove burner. Background Art

[0002] Gas stoves are very popular and are one of the most traditional kitchen appliances. However, the ignition success rate is a technical issue that needs to be continuously improved during the use of gas stoves. In the existing technology, the ignition pin of the inner ring fire cover of the gas stove is often close to a fire hole in the ignition area, serving as the ignition hole, but the distance from the other fire holes is different. Because the different distances from the fire holes will lead to differences in ignition efficiency, the ignition hole closer to the ignition pin often has the highest ignition success rate. However, if the ignition hole encounters a problem during ignition and cannot ignite normally, the other fire holes at a longer distance will also fail to ignite well, ultimately making it impossible to ensure an optimal ignition success rate. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a stove burner in order to overcome the defect that the ignition structure setting in the inner ring fire cover in the prior art has problems resulting in a low ignition success rate.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A stove burner includes an inner ring fire cover and an ignition structure. The outer wall surface of the inner ring fire cover has an inwardly recessed ignition groove. The ignition structure is located in the ignition groove. The inner ring fire cover is provided with a plurality of ignition holes. The plurality of ignition holes extend outward from the inner wall surface of the inner ring fire cover into the ignition groove. The plurality of ignition holes face the ignition structure.

[0006] In this solution, an inner ring fire cover and an ignition structure corresponding thereto are provided in the stove burner, and an ignition groove is provided in the inner ring fire cover, so that the ignition structure can complete ignition in the ignition groove, providing an ignition environment for the ignition structure. At the same time, limiting the placement of the ignition structure in the ignition groove also saves space in the stove burner; and the ignition holes on the inner ring fire cover all extend outward from the inner wall surface of the inner ring fire cover into the ignition groove, and the ignition holes are all facing the ignition structure, ensuring that the gas can flow smoothly into the ignition groove. At the same time, the ignition structure is equidistant from several ignition holes, which can solve the problem of poor ignition success rate in the prior art due to the difference in the distance between the ignition structure and the ignition hole.

[0007] Preferably, the distances between the plurality of ignition holes and the ignition structure are equal.

[0008] In this solution, since the plurality of ignition holes are arranged on the wall surface of the annular ignition groove, the plurality of ignition holes are equidistant from the ignition groove. Therefore, even if one end of the ignition hole is blocked, the other ignition holes can still play the same role, thereby ensuring the success rate of ignition.

[0009] Preferably, the ignition structure is an ignition needle, which includes a needle body and a support component. The support component is located outside the ignition groove, one end of the needle body is connected to the support component, and the other end of the needle body extends into the ignition groove.

[0010] In this solution, the ignition needle is mainly composed of a needle body and a supporting component. The supporting component is connected to one end of the needle body to fix the needle body, so that the needle body and the supporting component are fixed to the stove burner together. At the same time, the other end of the needle body extends into the ignition groove to facilitate ignition. The gas and air can mix in the ignition groove and directly combine with the ignition needle to complete ignition, which is convenient and quick, and improves the ignition success rate.

[0011] Preferably, the needle body comprises an ignition component and a connecting component, and the connecting component is connected to the supporting component;

[0012] The bottom of the ignition groove is annular, and the plurality of ignition holes are all located at the bottom of the ignition groove;

[0013] The ignition component is annular in shape and is located in the ignition groove. The end of the ignition component is connected to the connecting component. There is a distance between the end of the ignition component and the front end of the ignition component. Several ignition holes are all facing the ignition component.

[0014] In this solution, the needle body is mainly composed of an ignition component and a connecting component. The connecting component can be directly connected to the supporting component to drive the ignition component connected to the connecting component to be fixed as well, and finally the needle body can be fixed on the supporting component; at the same time, since the bottom of the ignition groove is set to be annular, the ignition holes set on the ignition groove are also distributed in a ring shape on the ignition groove; finally, the ignition component is also set to be annular, and because the ignition component is set in the ignition groove, the ignition component and the ignition groove are both annular, so the ignition holes on the ignition groove are at the same distance from the ignition component, which greatly improves the ignition success rate.

[0015] Preferably, the distance between the ignition component and the upper end of the inner ring fire cover is S1, and the distance between the ignition component and the ignition hole is S2, S1>S2.

[0016] In this solution, the larger area of ​​S1 can provide a larger mixing space, which is conducive to the external air flowing into the ignition groove from the second air hole to have a space to fully mix with the gas. After the two are fully mixed, they will contact the ignition structure to ensure the success rate of ignition; at the same time, S1 is set relatively small to ensure that the distance between the annular ignition structure and each ignition hole is equal, ensuring a more accurate distance, and also facilitating contact with the gas to complete ignition.

[0017] Preferably, the distance between the end of the ignition component and the front end of the ignition needle is S3, S3>S1>S2.

[0018] In this solution, S3 is set to the maximum, which can play a protective role. Because the ignition component needs to be energized, if the front end of the ignition component and the end of the ignition component are too close, adverse reactions such as leakage are likely to occur, resulting in an increased degree of danger. Therefore, this setting can play a protective role.

[0019] Preferably, a first air hole is provided on the inner ring fire cover, and the first air hole passes through the outer wall surface of the inner ring fire cover to the inner wall surface of the ignition groove and is connected with the ignition groove. The first air hole is located at the notch of the ignition groove.

[0020] In this solution, the first air hole is distributed at the ignition slot. At the same time, the first air hole runs through the outer wall of the inner ring fire cover to the inner wall of the ignition slot, ensuring that the air can flow smoothly into the ignition slot through the first air hole and be fully mixed with the gas to ensure the combustion success rate.

[0021] Preferably, a plurality of second air holes are provided on the top of the inner ring fire cover, and a plurality of main fire holes are provided on the outer wall of the inner ring fire cover. The plurality of second air holes are located above the main fire holes, and the second air holes pass through the outer wall of the inner ring fire cover to the inner wall of the ignition groove and are connected with the inside of the ignition groove.

[0022] In this solution, the second air hole opened on the top of the inner ring fire cover is located above the main fire hole, providing a second way for external air to circulate into the ignition groove. Similarly, the second air hole is also set on the outer wall surface of the inner ring fire cover, penetrates into the inner wall surface of the ignition groove and is connected with the ignition groove, ensuring that the air can flow smoothly into the ignition groove and improving the ignition success rate.

[0023] Preferably, a plurality of the second air holes are located above a plurality of the ignition holes, and a plurality of the second air holes and a plurality of the ignition holes are arranged alternately.

[0024] In this solution, the second air hole is also located above the ignition hole. Several second air holes are staggered with the main fire hole. Multiple second air holes and ignition holes can be set in a limited space, so that more air and gas can be mixed, increasing the amount of air during ignition while also improving the ignition success rate.

[0025] Preferably, the inner ring fire cover includes an inner ring fire cover body and an anti-blocking brim, the anti-blocking brim is arranged on the upper part of the inner ring fire cover body and can block the ignition structure, and the top of the anti-blocking brim has an inwardly concave liquid accumulation groove.

[0026] In this solution, the anti-blocking cap edge is arranged on the upper part of the inner ring fire cover body so that it can block the ignition structure. When placed in combustion, it may produce related substances such as water, affecting normal ignition and ignition success rate, and play an anti-blocking role. At the same time, a liquid accumulation groove is provided on the top of the anti-blocking cap edge, and the liquid accumulation groove is concave inward, so the liquid accumulated on the liquid accumulation groove can be stably accumulated in the liquid accumulation groove, and is not easy to flow out, thereby avoiding affecting the ignition success rate.

[0027] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0028] The positive progressive effect of the present invention is that: in the present invention, by arranging an inner ring fire cover and an ignition structure corresponding thereto in the stove burner, and at the same time arranging an ignition groove in the inner ring fire cover, the ignition structure can complete ignition in the ignition groove, providing an ignition environment for the ignition structure. At the same time, limiting the ignition structure to be placed in the ignition groove also saves space in the stove burner; and, the ignition holes on the inner ring fire cover all extend outward from the inner wall surface of the inner ring fire cover into the ignition groove and the ignition holes all face the ignition structure, ensuring that the gas can flow smoothly into the ignition groove. At the same time, the ignition structure is equidistant from several ignition holes, which can solve the problem of poor ignition success rate in the prior art due to the difference in the distance between the ignition structure and the ignition hole.

[0047] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0048] This embodiment discloses a stove burner 1, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the stove burner 1 includes an inner ring fire cover and an ignition structure 3. The outer wall surface of the inner ring fire cover has an inwardly recessed ignition groove. The ignition structure 3 is located in the ignition groove. The inner ring fire cover is provided with a plurality of ignition holes 21. The plurality of ignition holes 21 extend outward from the inner wall surface of the inner ring fire cover into the ignition groove. The plurality of ignition holes 21 are all facing the ignition structure 3. By providing an inner ring fire cover and an ignition structure 3 corresponding thereto in the stove burner 1, and providing an ignition groove in the inner ring fire cover, the ignition structure 3 can complete ignition in the ignition groove, providing an ignition environment for the ignition structure 3. At the same time, limiting the ignition structure 3 to be placed in the ignition groove also saves space in the stove burner 1; and, the ignition holes 21 on the inner ring fire cover all extend outward from the inner wall surface of the inner ring fire cover into the ignition groove, and the ignition holes 21 all face the ignition structure 3, ensuring that the gas can flow smoothly into the ignition groove. At the same time, the ignition structure 3 is equidistant from several ignition holes 21, which can solve the problem of poor ignition success rate in the prior art due to the difference in distance between the ignition structure 3 and the ignition hole 21.

[0049] like Figure 3 and Figure 4 As shown, specifically, the ignition area in the inner ring fire cover is shaped like a "water drop", and the ignition structure 3 and the ignition groove are both located in the ignition area, so the ignition holes 21 are evenly distributed along the ignition area.

[0050] The ignition holes 21 are equidistant from the ignition structure 3. Since the ignition holes 21 are arranged on the wall of the annular ignition groove, the ignition holes 21 are equidistant from the ignition groove. Therefore, even if one ignition hole 21 is blocked, the other ignition holes 21 can still play the same role, ensuring the success rate of ignition.

[0051] The ignition structure 3 is an ignition needle, which includes a needle body 31 and a support member 32. The support member 32 is located outside the ignition groove. One end of the needle body 31 is connected to the support member 32, and the other end of the needle body 31 extends into the ignition groove. The ignition needle is mainly composed of the needle body 31 and the support member 32. The support member 32 is connected to one end of the needle body 31 to fix the needle body 31, so that the needle body 31 and the support member 32 are fixed to the stove burner 1 together. At the same time, the other end of the needle body 31 extends into the ignition groove to facilitate ignition. Gas and air can mix in the ignition groove and directly combine with the ignition needle to complete ignition, which is convenient and fast, and improves the success rate of ignition.

[0052] like Figure 3 As shown, the needle body 31 includes an ignition component 311 and a connecting component 312, and the connecting component 312 is connected to the supporting component 32; the bottom of the ignition groove is annular, and several ignition holes 21 are all located at the bottom of the ignition groove; the ignition component 311 is annular in shape and is located in the ignition groove, the end of the ignition component 311 is connected to the connecting component 312, and there is a distance between the end of the ignition component 311 and the front end of the ignition component 311, and several ignition holes 21 are all facing the ignition component 311. The needle body 31 is mainly composed of an ignition component 311 and a connecting component 312. The connecting component 312 can be directly connected to the supporting component 32, thereby driving the ignition component 311 connected to the connecting component 312 to be fixed as well, and finally the needle body 31 is fixed on the supporting component 32; at the same time, since the bottom of the ignition groove is set to be annular, the ignition holes 21 set on the ignition groove are also distributed in a ring shape on the ignition groove; finally, the ignition component 311 is also set to be annular, and because the ignition component 311 is set in the ignition groove, the ignition component 311 and the ignition groove are both annular, so the ignition holes 21 on the ignition groove are at the same distance from the ignition component 311, which greatly improves the ignition success rate.

[0053] The distance between the ignition component 311 and the upper end of the inner ring fire cover is S1, and the distance between the ignition component 311 and the ignition hole 21 is S2, where S1>S2. The larger area of ​​S1 can provide a larger mixing space, which is conducive to the space for the external air to be fully mixed with the gas after flowing into the ignition groove from the second air hole 24. After the two are fully mixed, they will contact the ignition structure 3 to ensure the success rate of ignition. At the same time, S1 is set relatively small to ensure that the distance between the annular ignition structure 3 and each ignition hole 21 is equal, ensuring a more accurate distance and facilitating contact with the gas to complete ignition.

[0054] The distance between the end of the ignition component 311 and the front end of the ignition component 311 is S3, where S3>S1>S2. Setting S3 to the maximum value provides protection because the ignition component 311 requires electricity, and if the front end of the ignition component 311 and the end of the ignition component 311 are too close, leakage and other adverse reactions may occur, increasing the risk. Therefore, this setting provides protection.

[0055] Specifically, S1 refers to the vertical distance between the outer wall of the ignition component 311 and the horizontal plane where the upper end of the ignition groove is located, S2 refers to the straight-line distance between the outer wall of the ignition component 311 and the ignition hole 21 at the upper end, and S3 refers to the straight-line distance between the front end and the end of the needle body 31.

[0056] like Figure 2 、 Figure 3 and Figure 4 As shown, the inner ring fire cover is provided with a first air hole 23, which runs from the outer wall of the inner ring fire cover to the inner wall of the ignition groove and communicates with the ignition groove. The first air hole 23 is located at the notch of the ignition groove. The first air holes 23 are distributed at the notch of the ignition groove. At the same time, the first air holes 23 run from the outer wall of the inner ring fire cover to the inner wall of the ignition groove, ensuring that air can flow smoothly into the ignition groove through the first air holes 23 and fully mix with the gas to ensure the success rate of combustion.

[0057] like Figure 2 、 Figure 3 and Figure 4 As shown, the top of the inner ring fire cover is provided with a plurality of second air holes 24, and the outer wall of the inner ring fire cover is provided with a plurality of main fire holes 22. The plurality of second air holes 24 are located above the main fire holes 22, and the second air holes 24 penetrate from the outer wall of the inner ring fire cover to the inner wall of the ignition groove and communicate with the ignition groove. The second air holes 24 opened on the top of the inner ring fire cover are located above the main fire holes 22, providing a second way for external air to circulate into the ignition groove. Similarly, the second air holes 24 are also provided on the outer wall of the inner ring fire cover, penetrate to the inner wall of the ignition groove and communicate with the ignition groove, ensuring that air can flow smoothly into the ignition groove and improving the success rate of ignition.

[0058] Specifically, a plurality of main fire holes 22 are distributed circumferentially on the outer wall surface of the inner ring fire cover, and the second air holes 24 are located above the main fire holes 22 , and the second air holes 24 and the main fire holes 22 are staggered.

[0059] The plurality of second air holes 24 are located above the plurality of ignition holes 21, and the plurality of second air holes 24 are staggered with the plurality of ignition holes 21. The second air holes 24 are also located above the ignition holes 21. By staggering the plurality of second air holes 24 with the ignition holes 21, multiple second air holes 24 and ignition holes 21 can be arranged in a limited space, allowing more air and gas to mix, increasing the amount of air during ignition and improving the ignition success rate.

[0060] Specifically, the ignition area is distributed with upper and lower layers of holes. The upper layer of holes includes second air holes 24 and ignition holes 21, and the ignition holes 21 and second air holes 24 are staggered. The lower layer of holes is uniformly distributed ignition holes 21, among which the first air holes 23 extend from the outer wall of the inner ring fire cover to the inner wall of the ignition groove.

[0061] like Figure 5 As shown, the inner ring fire cover includes an inner ring fire cover body and an anti-blocking brim 25. The anti-blocking brim 25 is arranged on the upper part of the inner ring fire cover body and can block the ignition structure 3. The top of the anti-blocking brim 25 has an inwardly concave liquid accumulation groove 251. The anti-blocking brim 25 is arranged on the upper part of the inner ring fire cover body so that it can block the ignition structure 3. When placed in the fire cover, it may produce related substances such as water, affecting normal ignition and ignition success rate, and play an anti-blocking role. At the same time, the top of the anti-blocking brim 25 is provided with a liquid accumulation groove 251, and the liquid accumulation groove 251 is concave inward, so the liquid accumulated on the liquid accumulation groove 251 can be stably accumulated in the liquid accumulation groove 251 and is not easy to flow out, thereby avoiding affecting the ignition success rate.

[0062] Specifically, there is a certain gap between the anti-blocking cap edge 25 and the horizontal plane where the upper end of the ignition groove is located, so the anti-blocking cap edge 25 does not directly contact the inner ring fire cover body. The gap between the two can reserve more circulation space for external air, thereby improving the ignition success rate and avoiding wear caused by direct contact between the two.

[0063] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
