The inner exhaust port may be formed on an outer wall of the inner gas channel 110 facing the outer gas channel 120, the outer exhaust port may be formed on an outer wall of the outer gas channel 120 facing the inner gas channel 110, such that the inner exhaust port and the outer exhaust port are oppositely disposed, the gas in the inner gas channel 110 may be discharged to a gap between the inner gas channel 110 and the outer gas channel 120 through the inner exhaust port, the gas in the outer gas channel 120 may be discharged to a gap between the outer gas channel 120 and the inner gas channel 110 through the outer exhaust port, and the ignition pin 200 disposed between the outer gas channel 120 and the inner gas channel 110 may simultaneously ignite the mixture gas in the inner gas channel 110 and the outer gas channel 120. Thereby achieving the purpose of simplifying the structure of the combustion device of the application.

Of course, in other trial manners of this application, the inner exhaust port and the outer exhaust port may also be disposed in a staggered manner, or disposed opposite to each other, so that a plurality of ignition needles 200 may be correspondingly disposed to ignite the mixed gas in the inner combustion gas channel 110 and the outer combustion gas channel 120 correspondingly, and a plurality of pressing plates 400 and baffles 500 may be disposed to fix and enclose the plurality of ignition needles 200.

In some embodiments, the above baffle 500 may be disposed at a side of the ignition needle 200 facing the outer gas passage 120, so that the baffle 500 may be located between the ignition needle 200 and the outer gas passage 120, thereby blocking foreign materials entering the furnace body 100 from the outside of the furnace body 100 and components located at the outside of the furnace body 100 from impacting and colliding with the ignition needle 200.

Of course, the baffle 500 may also be disposed on a side of the ignition needle 200 facing the inner combustion gas channel 110, and thus may be disposed between the ignition needle 200 and the inner combustion gas channel 110, so as to block foreign matter entering the inner side of the furnace body 100 or components located on the inner side of the furnace body 100 from impacting and colliding with the ignition needle 200.

Alternatively, the shielding plate 500 may be provided in plural, and the plural shielding plates 500 may be respectively provided at plural sides of the ignition needle 200, so as to protect the ignition needle 200 in plural directions, so that the shielding plate 500 has a better protection effect on the ignition needle 200.

Still alternatively, the shielding plate 500 may be provided in a sleeve-like structure and the ignition needle 200 may be sleeved therein, so that the shielding plate 500 has an optimal protection effect on the ignition needle 200.

In some embodiments, in order to improve the stability and reliability of the baffle 500 after the baffle 500 is fixed, the protrusion 111 may be disposed on the inner combustion gas channel 110, and the groove 530 matched with the protrusion 111 may be disposed on the baffle 500, and the protrusion 111 on the inner combustion gas channel 110 may be removed and embedded in the groove 530 of the baffle 500, so that the protrusion 111 and the baffle 500 may abut against each other, so that the protrusion 111 and the baffle 500 may be limited by each other, so that the distance between the baffle 500 and the outer wall of the inner combustion gas channel 110 is fixed, and the baffle 500 may be prevented from shifting.

Specifically, the protrusion 111 may be disposed on the outer wall of the inner combustion gas channel 110, the groove 530 may be disposed on a side plate surface of the baffle 500 facing the outer wall of the inner combustion gas channel 110, and the groove 530 may penetrate the upper side end surface of the baffle 500, so that when the pressure plate 400 and the baffle 500 are mounted on the furnace body 100, the protrusion 111 and the groove 530 cooperate to position the pressure plate 400 and the baffle 500, so as to facilitate assembling the pressure plate 400 and the baffle 500 in place.

Of course, the number of the protrusions 111 and the number of the grooves 530 may be plural, and the number of the protrusions 111 corresponds to the number of the grooves 530, so that the plurality of protrusions 111 can be respectively embedded in the plurality of grooves 530, and thus the baffle 500 and the pressing plate 400 are more stable, and the assembling process is more precise.

The outer wall of the inner gas channel 110 may further be provided with a sleeve plate 112, the sleeve plate 110 may be provided with openings corresponding to the ignition needle 200 and the thermocouple 300, and the openings may be sleeved on the ignition needle 200 and the thermocouple 300, so as to further position the ignition needle 200 and the thermocouple 300, so that the ignition needle 200 and the thermocouple 300 may be more stable.

In some embodiments, in the case that the number of the pressing plates 400 is one, in order to reduce the volume of the pressing plates 400, the ignition needle 200 and the thermocouple 300 may be disposed close to each other, so that the ignition needle 200 and the thermocouple 300 may maintain a small distance, and thus when the pressing plates 400 press the ignition needle 200 and the thermocouple 300 at the same time, the area of the plate surface on the pressing plates 400 for pressing the ignition needle 200 and the thermocouple 300 may be correspondingly reduced, thereby making the pressing plates 400 more compact and reducing the difficulty of the manufacturing process of the pressing plates 400.

Specifically, the ignition needle 200 has a first connection line from the center to the center of the furnace body 100, the thermocouple 300 has a second connection line from the center to the center of the furnace body 100, and the first connection line and the second connection line form an angle of less than 180 degrees, so that the ignition needle 200 and the thermocouple 300 can be disposed closely.

Of course, the furnace body 100 may be further divided into the first side 130 and the second side 140 by a predetermined dividing line, which passes through the center of the furnace body 100, and when the bearing end surface of the furnace body 100 is circular, the predetermined dividing line may be equally divided into the furnace body 100. The ignition needle 200 and the thermocouple 300 may be simultaneously disposed at the first side 130 or the second side 140 of the furnace body 100, so that the ignition needle 200 and the thermocouple 300 are located at the same side of the furnace body 100, and thus, the interval between the ignition needle 200 and the thermocouple 300 may be reduced, and the pressing plate 400 may be more miniaturized.

Of course, in other embodiments of the present application, the number of the pressing plates 400 may be provided in plurality, and in the case where the pressing plates 400 are provided in plurality, the positions where the ignition needle 200 and the thermocouple 300 are provided may not be limited, and specifically, the ignition needle 200 and the thermocouple 300 may be provided on the first side 130 and the second side 140 of the furnace body 100, respectively, or on the same side of the furnace body 100 while maintaining a large interval. The plurality of pressing plates 400 can respectively press the ignition needle 200 and the thermocouple 300 on the furnace body 100, so that the arrangement positions of the ignition needle 200 and the thermocouple 300 can be freely arranged according to the specific structure of the furnace body 100 and the distribution condition of the components on the furnace body 100, and the structure of the combustion device can be more reasonable and compact.

In some embodiments, in order to protect the thermocouple 300, the baffle 500 may be disposed at least on one side of the thermocouple 300, so that the baffle 500 may prevent foreign materials entering the furnace body 100 and components on the furnace body 100 from colliding with the thermocouple 300 to damage the thermocouple 300, thereby improving the reliability of the thermocouple 300. Through the arrangement mode of the baffle 500, the baffle 500 can protect and shield the ignition needle 200 and the thermocouple 300, so that the baffle 500 has a stronger protection function.

Therefore, in order to reduce the volume of the baffle 500, the ignition needle 200 and the thermocouple 300 can be arranged close to each other on the same side, so that the area of the plate surface of the baffle 500 can be reduced under the condition that only one baffle 500 is arranged, and the volume of the baffle 500 is further reduced, and the structure of the combustion device is more compact.

In some embodiments, the first receiving groove 510 may be disposed on the baffle 500, and at least a portion of the ignition needle 200 may be disposed in the first receiving groove 510, so that the baffle 500 may enclose at least a portion of the ignition needle 200 therein, thereby making the baffle 500 have a better protection effect on the ignition needle 200. Specifically, the inner wall of the first receiving groove 510 may be opposite to the outer walls of the multiple sides of the ignition needle 200, so that the outer walls of the multiple sides of the ignition needle 200 are all located in the first receiving groove 510, and the outer walls of the multiple sides of the ignition needle 200 may be protected by the baffle 500.

The baffle 500 may further include a second receiving groove 520, and at least a portion of the thermocouple 300 may be disposed in the second receiving groove 520, such that the baffle 500 may further enclose at least a portion of the thermocouple 300 therein, thereby enabling the protection effect of the baffle 500 on the thermocouple 300 to be better. Specifically, the inner wall of the second receiving groove 520 may be opposite to the outer walls of the plurality of sides of the thermocouple 300, such that the outer walls of the plurality of sides of the thermocouple 300 are all located in the second receiving groove 520, and such that the outer walls of the plurality of sides of the thermocouple 300 may be protected by the barrier 500.
