The present embodiment discloses an ignition needle assembly and a gas cooker including the same, as shown in fig. 1 to 4, the gas cooker includes an ignition needle assembly 1, a burner 2 and a high temperature resistant insulation protection sleeve 3, the burner 2 is provided with a mounting hole 21 and a burner 22, the ignition needle assembly 1 is partially penetrated in the high temperature resistant insulation protection sleeve 3, and the high temperature resistant insulation protection sleeve 3 is at least partially penetrated in the mounting hole 21. The high-temperature-resistant insulating protective sleeve 3 is preferably made of high-temperature-resistant materials such as silicon rubber or polytetrafluoroethylene, so that the root of the ignition needle assembly 1 can be insulated and protected, the ignition needle assembly 1 can be fixed in the mounting hole 21 by utilizing the elastic deformation capability of the high-temperature-resistant insulating protective sleeve 3, the ignition needle assembly 1 is ensured to have no shaking after being mounted, and the ignition distance is ensured to be stable.
As shown in fig. 5 and 6, the ignition needle assembly 1 includes a pole needle 11, a housing 12, a wire 13, and an insulating sheath 14, the bottom end of the pole needle 11 is welded to the top end of the wire 13, and the housing 12 is wrapped around the pole needle 11 and the wire 13. Wherein the top end of the pole needle 11 protrudes from the top of the housing 12, and the bottom end of the wire 13 protrudes from the bottom end of the housing 12. The housing 12 is preferably made of a ceramic material with good insulating properties. The insulating sheath 14 is sleeved outside the wire 13 and partially penetrates the shell 12, so that the wire 13 is prevented from being leaked due to abrasion by the shell 12. As shown in fig. 2, the upper half part of the housing 12 is inserted into the mounting hole 21, and the lower half part is inserted into the high temperature resistant insulation protective sleeve 3, so that the high temperature resistant insulation protective sleeve 3 and the insulation protective sleeve 14 can perform double protection function on the wire 13.
At least one turn of firing tip 111 for discharge is formed in the circumferential direction outside the pole needle 11, and the firing tip 111 is located outside the housing 12. As shown in fig. 2, the firing tip 111 protrudes from the top end of the mounting hole 21. As shown in fig. 4, after the pole needle 11 rotates to an arbitrary position around its own axis, at least one ignition tip 111 can discharge toward the burner 22 on the burner 2, and the straight line with double arrow in fig. 4 is a discharge arc.
The ignition needle assembly 1 uses a plurality of ignition tips 111 which are annularly arranged to replace the existing unidirectional polar needle, no matter how the polar needle 11 rotates around the axis of the polar needle, at least one ignition tip 111 is arranged towards the burner 22, so that the charge current concentration during the discharge of the ignition needle assembly 1 can be ensured, the discharge is smooth, the ignition success rate is improved, and the problem that the unidirectional polar needle needs to be fixed in direction is solved. It is not necessary to install the ignition needle assembly with which of the firing tips 111 can be aligned with the burner 22 because all of the firing tips 111 function identically, and the installation efficiency is high and the installation difficulty is low.
The specific shape of the firing tip 111 is not limited, and it is sufficient to ensure sufficient discharge energy. In the present embodiment, the cross section of the ignition tip 111 is zigzag along the direction perpendicular to the axis of the pole needle 11. Discharge energy is concentrated at the tip end of the firing tip 111, and the firing success rate is high.
On the basis of the above structure, the ignition tip 111 extends in the axial direction of the pole needle 11 to form a rib 112. The ribs 112 can increase the strength of the firing tip 111, prevent the firing tip 111 from being damaged due to external impact, and prolong the service life of the ignition needle assembly 1.
In order to avoid the effect of ignition being affected after the pole needle 11 rotates around the axis of the pole needle by a certain angle, all the ignition tips 111 are symmetrically arranged relative to the axis of the pole needle 11. The firing tip 111 facing the burner 22 is identical regardless of how the pole needle 11 is turned, and the firing capability is stable.
The ignition tip 111 may be provided on the outer peripheral surface of the pole needle 11, and in this embodiment, the ignition tip 111 is located at the tip end of the pole needle 11, and the ignition tip 111 extends in the radial direction of the pole needle 11. The ignition tip 111 can be exposed only by extending a small section of the top end of the pole needle 11 out of the mounting hole 21, so that ignition can be normally performed, and interference with surrounding structures due to overlong extension of the top end of the pole needle 11 is avoided; in addition, the length of the top end of the pole needle 11 extending out of the mounting hole 21 is shortened, so that moment generated when external force impacts the pole needle 11 is reduced, and the probability of breaking the pole needle 11 is reduced.
Note that the above is only a preferred embodiment of the present utility model and the technical principle applied. It will be understood by those skilled in the art that the present utility model is not limited to the particular embodiments described herein, and that various obvious changes, modifications and substitutions may be made therein without departing from the scope of the utility model.
