The air inlet interface 23, the solenoid valve chamber 22, and the spool chamber are connected in sequence.

[0034] The main temperature control component 7 is provided with a lower main air outlet pipe 71.

[0035] The spool 4 is provided with a main air guide hole 41 and a lower long pilot flame guide hole 42.

[0036] The spool 4 is arranged in the spool chamber 21. The main air guide hole 41 cooperates with the connection points of the upper main fire airway 241, the upper long pilot flame airway 242, and the main control air outlet chamber 26 with the spool chamber 21. The lower long pilot flame guide hole 42 cooperates with the connection point of the lower long pilot flame outlet pipe 25 with the spool chamber 21.

[0037] Such as Figure 5 、 Figure 6 、 Figure 10 As shown, the lower long pilot flame guide hole 42 includes a circular hole portion 421 and an arc-shaped groove portion 422. The circular hole portion 421 is arranged at one end of the arc-shaped groove portion 422.
