So, can avoid the second clearance too big for it is spacing earlier between ferrule and the boss, lead to the problem that the ignition needle can not effectively be fixed.

Illustratively, the first gap is 0.1mm to 0.4 mm. For example, 0.1mm, 0.2mm, 0.3mm, 0.4mm and so on, so, can guarantee that the ferrule overlaps smoothly on first periphery wall, and can avoid first clearance too big and lead to effectively fixing the ferrule and then can not effectively fix the problem of ignition needle and thermocouple.

Illustratively, the second gap is between 0.15mm and 0.3 mm. For example, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc., so that the first ferrule can be ensured to be smoothly sleeved on the ignition needle, and the problem that the ignition needle cannot be effectively fixed due to the overlarge second gap can be avoided.

Exemplarily, the second ferrule has a second through hole, a distance between the first through hole and the central through hole is defined as L1, a distance between the second through hole and the central through hole is defined as L2, and L1 > L2. Therefore, the installation position requirements of the ignition needle and the thermocouple can be well adapted, and the ignition needle and the thermocouple can be effectively fixed.

Illustratively, the ignition needle has a third limit table surface, and the third limit table surface abuts against the upper end surface of the mounting table. So, when the installation point fire needle, can make the ignition needle from last down insert the mount table, it is spacing just to form with the up end of mount table through the spacing mesa of third, simple to operate.

The middle part of the upper end of the burner 10 is provided with a boss 110, the burner 10 is provided with a mounting table 120 outside the boss 110, the mounting table 120 is provided with a first mounting hole 121 and a second mounting hole 122, the ignition needle 20 is arranged in the first mounting hole 121 in a penetrating manner, the thermocouple 30 is arranged in the second mounting hole 122 in a penetrating manner, and the ignition needle 20 and the thermocouple 30 are connected on the mounting table 120 through a fixing structure 40.

The fixing structure 40 includes a ferrule 410 fitted over the boss 110, the ferrule 410 having a first ferrule 4110 and a second ferrule 4120 fitted over the ignition pin 20 and the thermocouple 30, respectively, the first ferrule 4110 having a first through hole 4111, and the second ferrule 4120 having a second through hole 4121.

The ignition needle 20 has a first limit land 21. The thermocouple 30 has a second stop surface 31, which abuts against the lower end surface 1201 of the mounting table 120, and a connecting section 32, to which a fastener (not shown in the drawings) is connected, which is capable of pressing down the second collar 4120 to abut the first collar 4110 against the first stop surface 21.

During installation, the ignition needle 20 is inserted into the first installation hole 121 from top to bottom above the installation platform 120, and the ignition needle 20 is in contact with the installation platform 120 through size restriction to form limiting; the thermocouple 30 is inserted into the second mounting hole 122 from below the mounting table 120 to the top, and the thermocouple 30 is limited by the contact with the mounting table 120 due to size constraint. Then, the ferrule 410 is sleeved on the boss 110 (in the process, the first through hole 4111 is aligned with the ignition pin 20, and the second through hole 4121 is aligned with the thermocouple), and then the thermocouple 30 is sleeved with a fastener for fixing, after the ferrule 410 is locked, the side deflection is generated, and the first ferrule 4110 abuts against the first limit table surface 21 of the ignition pin 20 under the lateral acting force for limiting.

In the burner, the ignition needle 20 and the thermocouple 30 are not easy to loosen and incline under the action of the hoop, that is, the hoop can simultaneously keep good positioning for the ignition needle and the thermocouple, and based on the arrangement of the connecting section 32 and the fastener, when the fastener presses the second hoop 4120, the first hoop 4110 can be attached to the first limiting table surface 21 of the ignition needle 20 under the transverse acting force, so that the adjustment is convenient, the distance from the near end (the near end is the end of the burner, which is closer to the small burner cap 50), the inclination control is also convenient, and the adjustment precision is more accurate.

As an exemplary embodiment, the ferrule 410 has a central through hole 4101, the boss 110 has a first peripheral wall 111, a first gap is formed between the first peripheral wall 111 and the central through hole 4101, when the ferrule 410 is sleeved on the boss 110, the central through hole 4101 needs to be aligned with the boss 110, and the ferrule 410 can be smoothly sleeved on the boss 110 by the first gap; the ignition needle 20 is provided with a second peripheral wall 22 at a position close to the first limiting table surface 21, a second gap is formed between the second peripheral wall 22 and the first through hole 4111, and when the hoop 410 is sleeved on the boss 110, the first through hole 4111 needs to be aligned with the ignition needle 20; the first gap is greater than the second gap. Therefore, the problem that the ignition needle 20 cannot be effectively fixed due to the fact that the second gap is too large and the hoop 410 and the boss 110 are limited in advance can be avoided.

Illustratively, the first gap is 0.1mm to 0.4mm, such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, etc., so as to ensure that the ferrule 410 is smoothly sleeved on the first peripheral wall 111, and avoid the problem that the first gap is too large to effectively fix the ferrule 410 and thus the fire needle 20 and the thermocouple 30.

Illustratively, the second gap is 0.15mm to 0.3mm, such as 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc., so that the first ferrule 4110 can be ensured to be smoothly sleeved on the ignition needle 20, and the problem that the ignition needle 20 cannot be effectively fixed due to the fact that the second gap is too large can be avoided.

As an exemplary embodiment, the connecting section 32 is threaded, and the fastener is a nut that is adjustably coupled to the threads, as shown in FIG. 6. Therefore, the purpose of adjustment can be achieved by screwing/unscrewing the nut, and the adjustment is more convenient.

The connection between the fastener and the connecting section 32 is not limited to a threaded connection, and in an embodiment not shown, the connection between the fastener and the connecting section 32 may also be a snap connection, such as: the connecting section 32 has a slot, and the fastening member may be an elastic clamp spring disposed in the slot. So, can reach the purpose of compressing tightly through establishing the elasticity jump ring card in the draw-in groove to, change different elasticity jump rings and can reach the regulation purpose.
