An embodiment of the utility model provides an ignition needle, including discharge head 100 and needle body 200, the outside cover of needle body 200 is equipped with interior sleeve pipe 400 of pottery, and the needle body 200 lower extreme is connected with wire 300, still includes supplementary ceramic pipe 600 in addition, and the cover is established and is met on wire 300 and with the interior sleeve pipe 400 lower extreme of pottery. The auxiliary ceramic tube 600 is connected to the lower end of the ceramic inner sleeve 400 to sleeve the easily-melted part of the lead 300, so that the easily-melted part of the lead 300 is separated from the outside, the lead 300 cannot be discharged to the outside of the auxiliary ceramic tube 600 under the condition of melting, the ignition needle can normally ignite, and the service life of the ignition needle is prolonged.

In some embodiments of the present invention, the present invention further comprises an outer sleeve 500, wherein the outer sleeve 500 is disposed outside the inner ceramic sleeve 400. The ceramic inner sleeve 400 can be protected by adding an outer sleeve 500, and the ignition needle is prevented from being broken off during installation.

In some embodiments of the present invention, the outer sleeve 500 is provided with a positioning structure, and the auxiliary ceramic tube 600 does not cover the positioning structure. Through setting up location structure, the installation location of the whole ignition needle of being convenient for, and set up supplementary ceramic pipe 600 and do not shelter from the location structure on the outer tube 500, make this location structure need not influenced by supplementary ceramic pipe 600, the ignition needle is outer rather than the cooperation structure that corresponds need not carry out great change, has avoided the waste of transforming the cost.

In some embodiments of the present invention, the positioning structure on the outer sleeve 500 is a positioning boss 510 provided on the outer surface. For example, referring to fig. 3, the lower portion of the outer sleeve 500 is provided with an annular positioning boss 510. The annular positioning boss 510 is arranged on the outer sleeve 500, so that the whole ignition needle can be conveniently installed and positioned.

It is contemplated that the positioning boss 510 may also be square, petal-shaped, or other irregular shapes, and may be configured according to an externally mounted structure, without limitation.

In some embodiments of the present invention, the auxiliary ceramic tube 600 is a bent structure. By arranging the auxiliary ceramic tube 600 to be of a bent structure, the length of the lead 300 sleeved by the auxiliary ceramic tube 600 can be longer in a limited space, and meanwhile, the situation that the auxiliary ceramic tube is arranged to be long-strip-shaped, which is equivalent to prolonging the waste installation space of the ignition needle, is avoided.

In some embodiments of the present invention, the inner wall of the bending portion of the auxiliary ceramic tube 600 abuts against the wire 300. Set to the structure of buckling through supplementary ceramic pipe 600, the department of bending inner wall and wire 300 butt simultaneously, the frictional force that the butt produced makes wire 300 fixed, prevents to become flexible.

In some embodiments of the present invention, the bending structure of the auxiliary ceramic tube 600 is L-shaped. For example, referring to fig. 1 to 3, the auxiliary ceramic tube 600 is provided in an L-shaped structure. Through setting up supplementary ceramic pipe 600 to L shape structure, the wire 300 length that can make supplementary ceramic pipe 600 cover in finite space is longer, and L shape structure is comparatively simple simultaneously, convenient assembling.

In some embodiments of the present invention, the bending portion of the L-shaped auxiliary ceramic tube 600 abuts against the wire 300. For example, referring to fig. 3, the auxiliary ceramic tube 600 has an L-shaped structure, the inner wall of the L-shaped bent portion abuts against the lead 300, and the lead 300 is fixed by the friction force generated at the abutting portion to prevent looseness.

In some embodiments of the present invention, the auxiliary ceramic tube 600 includes a vertical end 610 and a horizontal end 620, the vertical end 610 is connected to the inner ceramic sleeve 400, the horizontal end 620 is sleeved on the wire 300, and the vertical end 610 is shorter than the horizontal end 620. For example, referring to fig. 3, the auxiliary ceramic tube 600 is an L-shaped structure having a vertical end 610 and a horizontal end 620, and an upper portion of the vertical end 610 is sleeved with a lower portion of the inner ceramic sleeve 400, but the connection manner also includes, but is not limited to, a threaded connection, an adhesive connection, a snap connection, a fastener connection, and the like, and mainly plays a role in fixing the auxiliary ceramic tube 600. The horizontal end 620 serves to isolate the lead 300 from the outside by allowing the auxiliary ceramic tube 600 to surround one end of the lead 300. Meanwhile, the length of the vertical end 610 is shorter than that of the horizontal end 620, so that the vertical end 610 does not influence the positioning effect of the positioning structure on the outer sleeve 500 due to overlong, and the horizontal end 620 is longer in length and is more difficult to discharge outwards in a melting state due to the fact that the length of the protected lead 300 is longer.

In some embodiments of the present invention, the ceramic inner sleeve 400 is provided with a limiting structure, the limiting structure is provided with a protrusion 410 on the upper portion, and the lower end of the protrusion 410 abuts against the outer sleeve 500. For example, referring to fig. 3 and 4, a protrusion 410 having a large axial diameter is provided on the upper portion of the ceramic inner tube 400, and the lower end surface of the protrusion 410 abuts against the upper end surface of the outer tube 500. Through set up protruding portion 410 on ceramic inner tube 400, restrict the relative position between ceramic inner tube 400 and outer tube 500 to also can play the effect of spacing ceramic inner tube 400 through fixed outer tube 500, make ignition needle location accurate.

In some embodiments of the present invention, the present invention further comprises a positioning sleeve, which is sleeved outside the ceramic inner sleeve 400, and the upper end surface of the positioning sleeve abuts against the lower end surface of the outer sleeve 500. The position of the outer sleeve 500 in the vertical direction is limited by the matching of the positioning sleeve and the protruding part 410 on the ceramic inner sleeve 400, so that the outer sleeve 500 can also play a role of limiting the ceramic inner sleeve 400, and the ignition needle is accurately positioned.

In some embodiments of the present invention, the auxiliary ceramic tube 600 is L-shaped, and a plurality of protrusions 630 are disposed on the inner wall of the bending portion and the butt portion of the conducting wire. For example, referring to fig. 5 and 6, the protrusion 630 is formed at the contact portion between the inner wall of the bent portion of the L-shaped auxiliary ceramic tube 600 and the lead in a tooth shape. The friction force between the auxiliary ceramic tube 600 and the lead 300 is increased by providing the plurality of tooth-shaped protrusions 630, so that the lead 300 can be better fixed and prevented from loosening.

It is contemplated that the shape of the protrusions 630 may also be a cone or other irregular pattern, and is not limited herein.

In some embodiments of the present invention, the outer sleeve 500 may not be included, and the positioning structure is directly disposed on the inner ceramic sleeve 400. For example, referring to fig. 7, the locating structure provided on the ceramic inner sleeve is an annular boss 420. In this embodiment, the annular boss 420 is disposed on the ceramic inner sleeve 400, so that the whole ignition needle can be conveniently mounted and positioned, and the outer sleeve 500 is omitted, thereby saving the cost.
