The size relationship between the working end of the ignition pin 310 and the first mounting hole 221 is not limited. Preferably, the limiting protrusion 312b is annular, which helps to reduce the installation difficulty and simplify the installation process. The middle body 312 is an insulator, such as a ceramic body, and can insulate between the gas distribution plate 200 and the working end, and between the working end and the terminal, so as to ensure electrical safety.

Further, a limiting groove (not shown) is coaxially disposed on the air distribution plate 200 corresponding to the first mounting hole 221, and the limiting protrusion 312b is matched with the limiting groove. At this time, the limiting protrusion 312b is limited in the limiting groove, and the size of the limiting protrusion 312b is matched with that of the limiting groove, so that the centering performance of the ignition needle 310 during installation can be realized through the limiting protrusion 312b, and the first butt joint 313 and the first joint 401 of the ignition needle 310 can be smoothly butted and well contacted. Of course, in other embodiments, the body 312a and the first mounting hole 221 may be matched in size to achieve a smooth butt joint and good contact between the first pair of tabs 313 and the first tab 401.

Further, referring to fig. 4, the ignition needle 310 further includes a stopper 314 and an elastic member 315, the stopper 314 is detachably mounted on the body 312a and is located at a side of the gas distribution plate 200 close to the burner 100, the elastic member 315 is sleeved on the body 312a and is limited between the gas distribution plate 200 and the stopper 314, and the elastic member 315 is used for providing a pre-tightening force for pressing the gas distribution plate 200 and the limiting protrusion 312b against each other. When the fire needle 310 is installed, after the body 312a is installed in place (i.e., the limiting protrusion 312b abuts against the air distribution plate 200), the elastic member 315 is inserted into the body 312a, and then the stopper 314 is installed on the body 312 a. At this time, the elastic element 315 can generate a pretightening force under the limit of the gas distribution plate 200 and the stop element 314, and the gas distribution plate 200 and the limit protrusion 312b can be pressed against each other under the pretightening force to keep abutting, so that the ignition needle 310 is stably connected with the gas distribution plate 200. When the ignition needle 310 needs to be replaced, the stopper 314 is removed, the elastic member 315 is removed, and the body 312a is removed from the first mounting hole 221. In this embodiment, the retainer ring and the elastic member 315 are used to cooperate with the limiting protrusion 312b to realize stable connection between the ignition needle 310 and the gas distribution plate 200, so that the connection is reliable and the body 312a is convenient to disassemble and assemble.

Further, referring to fig. 5, the body 312a has an annular groove 312c recessed along a direction perpendicular to the first direction, the stopper 314 is sleeved on the annular groove 312c, and an outer wall of the stopper 314 protrudes compared with an outer wall of the body 312 a. At this time, the stop member 314 is a stop ring, the stop ring is disposed in the annular groove 312c and protrudes out of the body 312a, the elastic member 315 is limited between the stop ring and the gas distribution plate 200, and at this time, the stop ring can effectively support the elastic member 315, thereby ensuring the connection reliability of the ignition needle 310 and the gas distribution plate 200. In other embodiments, a connection hole may be formed in the body 312a along a direction perpendicular to the first direction, the stopper 314 is a stop rod, the stop rod is inserted into the connection hole, and the elastic member 315 may be supported by a portion of the stop rod outside the connection hole.

Among them, the elastic member 315 is preferably a spring.

Of course, in other embodiments, the ignition needle 310 may be stably connected to the gas distribution plate 200 by adopting other manners. For example, the body 312a is loosely fitted into the first mounting hole 221, or a locking nut is sleeved on the body 312a, the locking nut and the limiting protrusion 312b are located at both sides of the gas distribution plate 200, and the body 312a is locked with the gas distribution plate 200 by using the locking nut and the limiting protrusion 312 b.

In the embodiment, referring to fig. 4, the gas panel 200 has a fastening hole 230 communicating with the second mounting hole 222, the fastening hole 230 is disposed in a direction perpendicular to the first direction, and a fastening member for fixing the thermocouple 320 in the second mounting hole 222 is disposed in the fastening hole 230. Generally, the thermocouple 320 is in clearance fit with the second mounting hole 222, which facilitates the assembly and disassembly of the thermocouple. The fastener may apply a radial pressure to the thermocouple 320 to bring it into close contact with the wall of the second mounting hole 222. Of course, a recess may be formed in the side of the thermoelement 320, and the fastening member may be partially inserted into the recess so that the thermoelement 320 can be fixed in the second mounting hole 222. Wherein the fastening member may be a screw, and the fastening hole 230 may be a threaded hole. Of course, the fastener may be a pin, the fastening hole 230 a pin hole, etc.

When it is necessary to clean the gas range panel 600, the user may detach the gas distribution plate 200 (together with the central fire cover 700) from the burner 100 and simultaneously detach the ignition device 300 for cleaning. When the ignition device 300 is damaged, the user detaches the gas distribution plate 200 from the burner 100 and then replaces the ignition device 300 with the gas distribution plate 200. Compared with the prior art, when the gas stove is cleaned, the gas distribution disc 200 is only required to be detached without detaching the furnace end 100 and the gas stove panel 600, the ignition device 300 is detached synchronously, the periphery of the furnace end 100 can be cleaned, and the ignition device 300 is convenient to replace.
