As shown in connection with fig. 1-4. The utility model discloses a burner, which comprises a burner body 1 and an ignition needle 2, wherein the outer side surface of the burner body 1 is provided with a mounting part 3 with a mounting hole 30 for mounting the ignition needle 2; the burner also comprises a limit protector 4 and a fastener 5; the limit protection piece 4 is made of elastic deformation materials and is arranged between the mounting hole 30 and the ignition needle 2; the fastener 5 is fitted on the mounting portion 3, and the tip of the fastener 5 has an abutment portion 511, and the abutment portion 511 abuts the limit protector 4 to fix the ignition needle 2 in the mounting hole 30.

According to the burner disclosed by the utility model, the limit protector 4 is arranged between the mounting hole 30 and the ignition needle 2, so that soft contact is realized between the ignition needle 2 and the inner wall of the mounting hole 30 through the limit protector 4 made of elastic deformation materials, rigid hard contact is avoided between the ignition needle 2 and the inner wall of the mounting hole 30, meanwhile, when the abutting part 511 of the fastener 5 is abutted with the limit protector 4 to act on the ignition needle 2, enough acting force can be applied, the risk that the ceramic shell of the ignition needle 2 is cracked due to concentrated stress can be avoided, meanwhile, the ignition needle 2 can be firmly fixed in the mounting hole 30 and is not easy to loose and incline, and the reliability and the fastening performance of the ignition needle 2 are ensured so that the burner has better reliability.

The limiting protection piece 4 is made of elastic deformation materials such as high-temperature resistant rubber, high-temperature resistant silica gel and high-temperature resistant plastic, so that the problem that the limiting protection piece 4 is not easy to age and lose elastic deformation in the long-term use process of the burner is solved, the fact that soft contact is realized between the outer wall of the ignition needle 2 and the inner wall of the mounting hole 30 through the limiting protection piece 4 is ensured, and the ceramic outer wall which is usually adopted by the ignition needle 2 is protected from being cracked to generate electric leakage.

In some embodiments, the limit guard 4 comprises: the force dissipation block 41, the outer side of the force dissipation block 41 is provided with a plane-shaped stress surface 411, the abutting part 511 of the fastening piece 5 is abutted with the stress surface 411, and the inner side of the force dissipation block 41 opposite to the stress surface 411 is provided with an intrados surface matched with the outer wall of the ignition needle 2; a protective sleeve 42 is wrapped around the outer wall of the ignition needle 2 so that the outer wall of the ignition needle 2 and the inner wall of the mounting hole 30 are in "soft contact" through the protective sleeve 42.

The abutting portion 511 of the fastener 5 abuts against the planar force receiving surface 411, so that the force receiving portion of the abutting portion 511 on the force dissipating block 41 changes from a point to a surface with a larger area, and the force receiving area is larger, and the pressing force of the abutting portion 511 of the fastener 5 on the force dissipating block 41 is dispersed; meanwhile, the extrusion force is further diffused through the inner cambered surface of the force dispersing block 41 to act on the outer wall of the ignition needle 2, so that the fastener 5 can be ensured to generate larger extrusion force on the force dispersing block 41, the ignition needle 2 is ensured to be fixed firmly and cannot be loosened, and meanwhile, the ceramic outer wall of the ignition needle 2 is also protected from being cracked under the action of the extrusion force.

The wall thickness of the force dissipating block 41 is greater than the wall thickness of the protective sleeve 42. The force dissipation block 41 is provided with a larger wall thickness, so that the dispersing capability of the force dissipation block 41 to the extrusion force is improved, and the extrusion force is further prevented from being concentrated at the joint of the stress surface 411 of the force dissipation block 41 and the joint part 511, thereby being beneficial to protecting the ignition needle 2.

In some embodiments, the force dissipating block 41 is integrally formed with the protective sheath 42, and the two are connected to form an integral collar. During assembly, the ring sleeve is arranged in the mounting hole 30, and after the lower end of the ignition needle 2 passes through the ring sleeve structure, the ignition needle 2 is assembled on the mounting part 3 by using the fastener 5 and is abutted against the stress surface 411 of the force dissipation block 41 through the abutting part 511 to generate a pressing force for fixing the ignition needle 2 in the mounting hole 30.

Correspondingly, the lower end of the ignition needle 2 is provided with the limiting ring 21, when the lower end of the ignition needle 2 is inserted into the annular sleeve, the limiting ring 21 presses the cap peak 43 on the step 301, so that the annular sleeve is prevented from generating axial movement relative to the ignition needle 2 in the use process, and the fixation of the ignition needle 2 is ensured to be firm and reliable.

In some embodiments, the force dissipating block 41 and the protective sleeve 42 may be separate structures. For example, when the protective sleeve 42 is fitted over the lower end of the ignition needle 2 and the force dissipation block 41 is separated from the protective sleeve 42, the ignition needle 2 is fixed in the mounting hole 30 by the pressing force generated by the abutting portion 511 of the fastener 5 against the force dissipation block 41. It is envisioned that when the force dissipating block 41 and the protective sleeve 42 are of a split construction, the operation of securing the ignition needle 2 is not as convenient as if they were an integral construction.

The mounting hole 30 is provided with a part of the inner wall opposite to the mounting surface 31 as a planar vertical inner wall 33, and the vertical inner wall 33 is abutted against the stress surface 411 of the force dissipation block 41 to play a radial limiting role on the force dissipation block 41 in the mounting hole 30, so that the limiting protector 4 cannot rotate in the mounting hole 30, and the abutting part 511 is ensured to be abutted against and connected with the stress surface 411 to improve the reliability of the fixing structure of the ignition needle 2.

In some embodiments, the fastening portion 51 is in threaded fastening fit with the assembly groove 32, and the pressing force of the fastener 5 on the limit protector 4 can be adjusted by adjusting the threaded fastening degree of the fastening portion 51 relative to the assembly groove 32.
