The ignition needle generally includes an electrode including a discharge end and a conductive end, and a protective shell surrounding the conductive end of the electrode with the discharge end of the electrode exposed. The existing ignition needle for the gas burner is generally provided with an electrode, the electrode is used as a discharge end, and a fire cover of the gas burner is used as a receiving end, so that the ignition needle has the problems of poor universality and low ignition success rate.
Disclosure of Invention
The first technical problem to be solved by the invention is to provide an ignition needle with good universality aiming at the prior art.
The second technical problem to be solved by the invention is to provide an ignition needle with high ignition success rate aiming at the prior art.
The third technical problem to be solved by the invention is to provide a gas burner with high ignition success rate aiming at the prior art.
The technical scheme adopted by the invention for solving the first and second technical problems is as follows: an ignition needle comprising a protective shell and an electrode needle inserted in the protective shell, one end of the electrode needle being exposed to the protective shell, characterized in that the electrode needle comprises a first electrode needle and a second electrode needle, which can both be a discharge end or a receiving end.
Preferably, the exposed sections of the first electrode needle and the second electrode needle are respectively located at different height positions with a gap left between the exposed sections. The exposed section of one of the first electrode needle or the second electrode needle can be selected as the discharge end according to the difference of the height of the ignition needle on the inner ring fire cover.
Preferably, the exposed section of the first electrode needle is higher than the exposed section of the second electrode needle, and the exposed section of the first electrode needle is bent in a direction away from the protective shell where the first electrode needle is located. When the first electrode needle is used as a discharge end, the density of fuel gas is higher than that of air, so that the fuel gas density of the area where the exposed section of the first electrode needle is positioned is higher, and the spark can be deflected to the direction of the inner ring fire cover through bending treatment, so that the ignition success rate is improved.
Preferably, after the exposed section of the first electrode needle extends horizontally to the direction of the second electrode needle, the end of the exposed section of the first electrode needle is bent away from the direction of the protective shell where the first electrode needle is located.
Preferably, the exposed section of the second electrode needle extends vertically upwards.
Preferably, the protective housing includes first cylinder and second cylinder that are used for inserting above-mentioned first electrode needle and second electrode needle respectively, and this first cylinder and the vertical interval setting of second cylinder are connected through the connecting block between the two, and in the cross section of this connecting block, the limit that is located first electrode needle bending direction side is circular-arc. Therefore, the ignition needle can be more tightly arranged on one side of the inner ring fire cover and can be closer to the fire hole on the inner ring fire cover, so that the concentration of a gas area where the ignition needle is positioned is higher, the ignition success rate is further ensured, the distance from the first electrode needle to the inner ring fire cover and the distance from the second electrode needle to the inner ring fire cover are equal, and the ignition distance is equal to the distance from the first electrode needle to the inner ring fire cover.
The invention solves the third technical problem by adopting the technical scheme that: the gas burner with the ignition needle comprises a cylindrical inner ring fire cover, wherein an ignition region is arranged on the side wall of the inner ring fire cover, and an ignition hole is formed in the ignition region.
Preferably, the distance from the end of the exposed section of the first electrode needle to the ignition region is equal to the distance between the end of the exposed section of the first electrode needle and the end of the exposed section of the second electrode needle. When the first electrode needle is a discharge end, the discharge end discharges, and as the ignition distance is equal to the distance from the first electrode needle to the inner ring fire cover, sparks randomly strike the inner ring fire cover and the receiving end (the second electrode needle), and the area is a fuel gas area and can be smoothly ignited; when one end of the ignition is in failure, the spark can be grounded through the other channel, so that the ignition success in the extreme case is ensured. Namely, when the first electrode needle is used as a discharge end, the second electrode needle and the fire cover can be used as receiving ends at the same time, and when one end of the first electrode needle is grounded and fails, the other end of the first electrode needle can be grounded. When the second electrode needle is a discharge end, current is led to the upper end from the lower end, the fuel gas is ignited through the fuel gas area, and if the first electrode needle is in failure in grounding, the spark is bridged to the inner ring fire cover through the first electrode needle, so that the ignition can be ensured.
Preferably, the exposed section of the first electrode needle is higher than the exposed section of the second electrode needle, and the exposed section of the first electrode needle is bent towards the inner ring fire cover, so that the spark can be deflected towards the inner ring fire cover, and the ignition success rate is improved.
Further, the exposed section of the second electrode needle extends vertically upwards, and after the exposed section of the first electrode needle extends horizontally towards the direction of the second electrode needle, the exposed section of the first electrode needle is bent towards the direction of the inner ring fire cover.
Compared with the prior art, the invention has the advantages that: the ignition needle is provided with the first electrode needle and the second electrode needle, and the first electrode needle and the second electrode needle can be used as a discharge end or a receiving end, so that the universality of the ignition needle can be improved, when one electrode needle is used as the discharge end, the other electrode needle and the inner ring fire cover can be used as the receiving end at the same time, and when one end of the electrode needle is grounded and fails, the other end of the electrode needle can be grounded through the other channel, so that the success rate of ignition is remarkably improved.

As shown in fig. 3 to 5, a gas burner comprises a cylindrical inner ring fire cover 4, wherein an ignition region 5 is arranged on the side wall of the inner ring fire cover 4, and an ignition hole 51 is arranged on the ignition region 5. One side of the inner ring fire cover 4 is provided with an ignition needle including a protective case 1 and an electrode needle inserted in the protective case 1, one end of which is exposed to the protective case 1, as shown in fig. 1 and 2. In this embodiment, the electrode pin includes a first electrode pin 2 and a second electrode pin 3, the protective housing 1 includes a first cylinder 11 and a second cylinder 12 respectively used for inserting the first electrode pin 2 and the second electrode pin 3, the first cylinder 11 and the second cylinder 12 are vertically spaced and arranged, and are connected through a connecting block 13, in a cross section of the connecting block 13, a side located at a bending direction side of the first electrode pin 2 is in a circular arc shape, so that the ignition pin can be more tightly arranged at one side of the inner ring fire cover 4 and can be closer to a fire hole on the inner ring fire cover 4, thereby enabling a concentration of a gas area where the ignition pin is located to be higher, further guaranteeing an ignition success rate, and enabling a distance from the first electrode pin 2 and the second electrode pin 3 to be equal to a distance from the inner ring fire cover 4 and enabling an ignition distance to be equal to a distance from the first electrode pin 2 and the second electrode pin 3 to the inner ring fire cover 4.
In addition, two electrode pins are arranged in the embodiment, so that the exposed section of each electrode pin can serve as a discharge end and a receiving end, and the universality of the ignition pin is improved. Further, the exposed sections 21,31 of the first electrode needle 2 and the second electrode needle 3 are respectively positioned at different height positions with a gap left between them, and the heights of the first electrode needle 2 and the second electrode needle 3 are different, so that one of the first electrode needle 2 and the second electrode needle 3 can be selected as a discharge end according to the difference of the heights of the ignition holes on the inner ring fire cover 4.
In this embodiment, the exposed section 21 of the first electrode needle 2 is higher than the exposed section 31 of the second electrode needle 3, and the exposed section 21 of the first electrode needle 2 is bent in a direction away from the protective shell 1 where the first electrode needle 2 is located, so that when the first electrode needle 2 is used as a discharge end, the spark can be biased toward the inner ring fire cover 4, thereby improving the ignition success rate. Further, the exposed section 31 of the second electrode needle 3 extends vertically upwards, and after the exposed section 21 of the first electrode needle 2 extends horizontally towards the direction of the second electrode needle 3, the end of the exposed section is bent towards the direction away from the protective shell 1 where the first electrode needle 2 is located. In this embodiment, the bending direction is toward the inner ring fire cover 4.
Further, in the present embodiment, the distance a from the end 211a of the exposed section 21 of the first electrode pin 2 to the ignition region 5 described above is equal to the distance b between the end 211a of the exposed section 21 of the first electrode pin 2 and the end 311a of the exposed section 31 of the second electrode pin 3.
In this example embodiment, when the first electrode needle 2 is the discharge end, the discharge end discharges, and since the ignition distance is equal to the distance from the first electrode needle 2 to the inner ring fire cover 4, sparks strike the inner ring fire cover 4 and the receiving end (the second electrode needle 3) at random, and the area is a gas area which can be ignited smoothly; when one end of the ignition is in failure, the spark can be grounded through the other channel, so that the ignition success in the extreme case is ensured. I.e. when the first electrode needle 2 is used as a discharge end, the second electrode needle 3 and the fire cover 4 can be used as receiving ends at the same time, and when one end of the two ends is grounded and fails, the other end of the two ends can be grounded.
When the second electrode needle 3 is a discharge end, current is led to the upper end from the lower end, the fuel gas is ignited through the fuel gas area, and if the first electrode needle 2 fails in grounding, the spark is bridged to the inner ring fire cover 4 through the first electrode needle 2, so that the ignition can be ensured.
