The burner head 1 is provided with a mounting seat 11, and the mounting seat 11 is provided with a through hole 12. When the burner head 1 is placed horizontally, the axial direction of the through hole 12 is along the vertical direction, and the through hole 12 penetrates through the top and bottom of the mounting seat 11. The ignition needle 2 vertically passes through the mounting seat 11 through the through hole 12. A first limiting portion 21 is provided on the outer wall of the ignition needle 2, and the first limiting portion 21 abuts against the top of the mounting seat 11 to provide support for the ignition needle 2 through the mounting seat 11. A second limiting portion 22 is also provided on the outer wall of the ignition needle 2. The second limiting portion 22 is located below the bottom of the mounting seat 11. The spring card 3 is inserted between the bottom of the mounting seat 11 and the second limiting portion 22. Both ends of the spring card 3 in the first direction a are formed with support platforms 31, and both support platforms 31 abut against the bottom of the mounting seat 11. The spring card 3 between the two support platforms 31 is recessed downward to form an arc portion 32, and the arc portion 32 abuts against the second limiting portion 22, so as to axially limit the ignition needle 2 through the spring card 3, realize the installation of the ignition needle 2 on the mounting seat 11 of the burner head 1. When installing the ignition needle 2, only need to insert the ignition needle 2 into the through hole 12 of the mounting seat 11, make the first limiting portion 21 of the ignition needle 2 support on the mounting seat 11, and then insert the spring card 3 between the bottom of the mounting seat 11 and the second limiting portion 22. When disassembling the ignition needle 2, only need to pull out the spring card 3 to pull out the ignition needle 2 from the through hole 12 of the mounting seat 11. Thus, the disassembly and assembly of the ignition needle 2 are more convenient through the ignition needle mounting structure of the present application, and the ignition needle 2 will not be damaged during the disassembly and assembly process.

[0038] In this embodiment, preferably, as Figure 5 shown, when the ignition needle 2 is inserted into the through hole 12 of the mounting seat 11 and the first limiting portion 21 abuts against the top of the mounting seat 11, the distance between the second limiting portion 22 and the bottom of the mounting seat 11 is d, and the depression depth of the arc portion 32 of the spring card 3 is h, d ≤ h. Thus, when the spring card 3 is inserted between the second limiting portion 22 and the bottom of the mounting seat 11, the arc portion 32 of the spring card 3 can just abut against the second limiting portion 22, or the arc portion 32 abuts against the second limiting portion 22 in a compressed state, and further axially limit the ignition needle 2 through the spring card 3.

[0039] In an embodiment of the present application, preferably, as Figures 1 to 4 shown, the second limiting portion 22 is annular along the circumferential direction of the ignition needle 2. One end of the spring card in the first direction a is formed with a U-shaped opening 33.
