Description

Technical Field

[0001] The present application relates to the field of lighters, and in particular to a lighter. Background Art

[0002] A lighter is a small fire-making device. It is mainly used for making fire, smoking, cooking and other fire-making. The main parts of a lighter are the ignition mechanism and the gas storage box. When the ignition mechanism is activated, sparks burst out and shoot towards the gas area to ignite the gas. The ignition mechanism is the most active part of the evolution of the lighter and also the part with a more complex structure. The gas used in the lighter is mainly combustible gas. In the early days, kerosene was mostly used, but now butane, propane and liquefied petroleum gas are mostly used. They are pressurized and filled into the gas storage box. Once released into the air, they absorb heat and vaporize and expand rapidly, making them very easy to ignite.

[0003] In the related art, a lighter includes a handle, a casing and an iron shell. The lower part of the handle is embedded in the casing, and the iron shell is arranged on the outer sides of the casing and the handle. The iron shell is used to protect the casing to reduce the breakage of the lighter when it falls.

[0004] Regarding the above-mentioned related technologies, since the button is relatively long and there is a gap between the button and the casing, when the lighter is turned on, electricity will jump from the seesaw position to the iron shell, posing a risk of leakage. When the user holds the lighter, the electricity that jumps to the iron shell will shock the user, and the user will subconsciously let go, and the lighter will fall, resulting in low safety.

The end of the block 63 away from the shell abuts against the mounting plate 12 in the slot 121. During the installation of the upper shell 6 to the mounting plate 12, the block 63 moves toward the slot 121 along the outer wall of the mounting plate 12, and a gap for the movement of the block is left between the inner wall of the upper shell 6 and the outer wall of the mounting plate 12. A fire outlet 61 is provided on the upper shell 6, and the upper shell 6 closes the vicinity of the lighter fire outlet 61 to reduce the situation where the wind blows out the flame when the lighter is used.

[0039] Reference Figure 2 and 5 The outer wall of the housing 1 is provided with a pressing groove 11 in the vertical direction. The housing 1 is slidably connected with a button 3 at the pressing groove 11. The lower end of the part of the button 3 that slides in the pressing groove 11 is located inside the iron shell 2. The housing 1 and the iron shell 2 form a groove with an upper end open at the pressing groove 11. The button 3 slides in the groove. A piezoelectric igniter 5 is provided inside the housing 1. The electricity generated by the piezoelectric igniter 5 cannot jump to the iron shell 2 through the gap between the housing 1 and the button 3, thereby reducing the risk of electric shock and improving safety. The iron shell 2 is provided with a notch 21 on the side wall near the pressing groove 11 to avoid the button 3 from sliding. When the user presses the button 3 with a finger, the finger can move up and down with the button 3 from the notch 21. The iron shell 2 will not block the finger.

The rocker 4 does not directly contact the nozzle 72. The tilting rod 721 is inserted into the rocker 4 to limit the rocker 4. When the rocker 4 tilts the nozzle 72, the situation of the rocker 4 being separated from the nozzle 72 is reduced.

[0044] The implementation principle of a lighter in an embodiment of the present application is as follows: the upper end of the outer wall of the casing 1 and the upper end of the inner wall of the iron shell 2 are fitted together, the casing 1 and the iron shell 2 form a groove with an upper end open at the pressing groove 11, and the button 3 slides in the vertical direction in this cavity. The user presses the button 3, and the pressing block 31 drives the seesaw 4 to rotate. The seesaw 4 applies pressure to the piezoelectric igniter 5, thereby triggering the piezoelectric igniter 5. When the piezoelectric igniter 5 emits an electric spark, the other end of the seesaw 4 drives the nozzle 72 to tilt up, opens the air outlet valve 7, and the electric spark ignites the gas, and the flame emerges from the fire outlet 61. The pressing block 31 of the button 3 is inside the casing 1, and the sliding part is fitted outside the casing 1.
