Specific Embodiments

[0015] Such as Figure 1 , Figure 2As shown in the figure, a leak-proof lighter with an independent configuration of an air outlet valve and an air regulating valve according to an embodiment of the present invention includes a body 1 and an igniter 2 disposed on the body 1. The igniter 2 is a common piezoelectric ignition assembly, and its structure will not be described in detail herein. The body 1 has an inner cavity 11 for storing oil, and a channel 12 is also formed on the body 1. The channel 12 is used to convey the oil in the inner cavity 11 to the nozzle of the igniter 2. An air outlet valve 3 and an air regulating valve 4 are also disposed on the body 1. The air outlet valve 3 and the air regulating valve 4 are independently configured. More specifically, a joint portion 13 is formed on the body 1, and a middle hole 131 is formed on the joint portion 13. The inner cavity 11 is communicated with the channel 12 through the middle hole 131. The air outlet valve 3 is disposed above the joint portion 13, and the air regulating valve 4 is disposed below the joint portion 13; the air outlet valve 3 includes a valve body 31 and a valve core 32. The valve body 31 is connected to the body 1 by a thread and is sealed by a sealing member. The sealing member is generally an O-ring (not shown in the figure) sleeved outside the valve body 31. The valve core 32 is movably disposed in the valve body 31 and is acted on by an elastic member. The elastic member is generally a spring (not shown in the figure). The elastic member makes the valve core 32 have a downward movement tendency so as to keep the middle hole 131 blocked; the air regulating valve 4 includes a core tube 41 having a cavity 411. Communication holes 412 are formed at both the upper and lower ends of the core tube 41. The lower part of the core tube 41 is connected to the body 1 by a thread and is sealed by a sealing member. The sealing member is two O-rings (not shown in the figure). The upper part of the core tube 41 has an extension column 413 extending into the middle hole 131, and a plurality of sponge pads 42 are sleeved outside the extension column 413; for easy processing and forming, the core tube 41 includes an upper tube body 41a and a lower tube body 41b. The upper tube body 41a and the lower tube body 41b are integrally formed by interference fit and ensure the sealing performance of the insertion part. One communication hole 412 is formed at the upper end of the upper tube body 41a, and the other communication hole 412 is formed at the lower end of the lower tube body 41b; an installation groove 41a1 is also formed on the upper tube body 41a, and an O-ring is disposed at the installation groove 41a1; a bottom cover 5 is further provided at the lower part of the body 1. When the bottom cover 5 is opened and the core tube 41 is rotated by a special tool, the pressure state of the sponge pads 42 is changed, that is, the adjustment of the flame size and height of the lighter is realized.

[0016] The air outlet valve and the air regulating valve are independently configured. When the air regulating valve is adjusted, it will not affect the air outlet valve, and it is not easy to leak at the air outlet valve, so the service life of the product is extended.

[0017] During specific use, for easy understanding of the present invention, it will be described in combination with the accompanying drawings;

[0018] During ignition, the control rod drives the valve core 32 to move axially upward. The valve core 32 no longer blocks the middle hole 131. The hydraulic oil in the inner cavity 11 sequentially passes through the lower communication hole 412, the cavity 411, the upper communication hole 412, the gap between the upper pipe body 41a and the joint part 13, the sponge pad 42 to the middle hole 131. At the same time, the hydraulic oil vaporizes and reaches the nozzle of the igniter 2 through the channel 12. At this time, the igniter 2 releases a high-voltage arc, causing the vaporized hydraulic oil to be ignited.

[0019] When it is necessary to adjust the size and height of the flame, open the bottom cover 5 and rotate the core pipe 41 (the upper pipe body 41a and the lower pipe body 41b rotate synchronously) through a special tool. The compression state of the sponge pad 42 changes, and the gap at this position changes, that is, the adjustment of the size and height of the flame of this lighter is realized. The more severely the sponge pad 42 is squeezed, the smaller and lower the flame; during the adjustment process, the valve body 31 is not affected, that is, the valve body 31 will not become loose due to multiple adjustments of the gas regulating valve 4, and this lighter is not prone to leakage.

[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
