[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] Example 1: According to Figures 1-3 As shown, this utility model provides a novel structure for the ignition head of a flint lighter, including a head component 1. The head component 1 is provided with a flint hole and a spring hole. Both ends of the outer diameter of the flint hole and the spring hole are elliptical holes 7, and a tie rod 2 is provided at the front end of the pry plate position.

[0025] The inner diameter of the elliptical inner hole of the firestone hole and the spring hole is provided with a second chamfered opening 3, and the outer diameter of the upper and lower ends of the elliptical inner hole is provided with a first chamfered opening 4. The first chamfered opening 4 is a double chamfer on both sides.

[0026] The machine head component 1 has a T-shaped opening 5 at the bottom of the pry plate. The top of the machine head component 1 has a chamfer 6 symmetrically placed at the grinding wheel position. The machine head component 1 is made of metal or alloy. The design of the elliptical hole 7 makes it easier for the machine head component 1 to cooperate with other components during assembly, reducing the assembly difficulty. The tie rod 2 is used to enhance the structural strength of the machine head component 1, prevent deformation or damage during assembly or use, and, more importantly, enable the pry plate to easily pry open the air valve.

[0027] Assembly process: Pre-processing, the head part 1 is mass-produced by injection molding process to ensure that the dimensional accuracy of the elliptical hole 7, chamfered opening, T-shaped through opening 5, etc. reaches ±0.05mm.

[0028] Component Installation: Insert the flint and spring into their corresponding holes, guiding them into place accurately using the second chamfered notch 3. Adjust the fitting angle between the head assembly 1 and other components using the curvature of the elliptical hole 7 to complete the initial assembly. Structural Reinforcement: Ensure the connection strength between the tie rod 2 and the head assembly 1, and importantly, ensure the function of easily prying open the air valve with a pry bar.

[0029] Functional Testing: Simulating operating table operation verifies the stability of the flint's ignition, the smoothness of the grinding wheel's rotation, and the ease of disassembly and reassembly of the pry bar. Improved Assembly Efficiency: The oval hole 7 and chamfered design reduce assembly time by 30% and lower the defect rate to below 1%. Structural Strength Verification: After 100,000 cycles of loading testing, the head component 1 showed no deformation or breakage, and the stress distribution in the tie rod area was uniform, effectively enabling the pry bar to easily pry open the air valve. The prying force was reduced to less than 5N. Overall, the product exhibits strong functional adaptability and smooth operation. After the grinding wheel is installed, the operating noise is reduced to 45dB, meeting the requirements of high-end products.
