[0002] An electronic lighter mainly includes a housing, an electronic igniter, a button, and a rocker arm. The housing serves as a gas storage component, with a gas nozzle and a spark chamber located at the top. The spark chamber contains a receiving compartment, and the electronic igniter is vertically mounted within the receiving compartment. The head of the rocker arm is engaged with the gas nozzle on the housing, while the tail of the rocker arm extends to the upper end of the electronic igniter. The button arm slides into the upper end of the receiving compartment, and its lower part abuts against the tail of the rocker arm and the top of the electronic igniter. To use it, simply press the button arm, which simultaneously activates the electronic igniter and the tail of the rocker arm, thus igniting the lighter. It is very simple and convenient to use.
[0003] Currently, most piezoelectric ceramic lighters on the market are ignited by a push-button mechanism. Since these lighters are generally exposed, they are prone to ignition when accidentally touched during carrying or other activities, which can pose a safety hazard. Summary of the Invention

The lower end of the vertical shaft 6 extends into the air storage chamber 1a and is provided with a valve core assembly for controlling the opening or closing of the air intake pipe 2 between it and the lower end of the air intake pipe 2; the first horizontal plate 7 is provided with a flame outlet 7a; when the first horizontal plate 7 rotates to be directly above the through hole 1b, the flame outlet 7a and the through hole 1b are in a coaxial position, the valve core assembly opens the lower end opening of the air intake pipe 2, the second horizontal plate 8 is directly above the pressing block 5, at this time the second horizontal plate 8 is pressed, the second horizontal plate 8 drives the pressing block 5 to move downward; when the first horizontal plate 7 rotates to be directly above the pressing block 5, the valve core assembly closes the lower end opening of the air intake pipe 2, the second horizontal plate 8 is directly above the through hole 1b.
[0024] In this embodiment, the valve core assembly includes a valve core plate 9, an end plate 3 with a vertically upward extending connecting post 10, a first vertical rod 10a at the upper end of the connecting post 10, a second vertical rod 11 parallel to the first vertical rod 10a fixedly disposed within the air storage chamber 1a, the valve core plate 9 being slidably connected between the first vertical rod 10a and the second vertical rod 11 in a vertical direction, and a valve core rod 12 fixedly disposed on the valve core plate 9, the valve core rod 12 being used to open or close the lower end of the air intake pipe 2. The vertical shaft 6 has an opening at one end; a threaded rod 6a, threadedly connected to the valve core plate 9, is fixedly provided at the lower end of the vertical shaft 6. When the vertical shaft 6 rotates, the threaded rod 6a drives the valve core plate 9 to move upward or downward. When the first horizontal plate 7 rotates to directly above the through hole 1b, the threaded rod 6a drives the valve core plate 9 to move downward to the lower end position, opening the lower end opening of the air intake pipe 2. When the first horizontal plate 7 rotates to directly above the pressing block 5, the threaded rod 6a drives the valve core plate 9 to move upward to the upper end position, closing the lower end opening of the air intake pipe 2. When the valve core plate 9 is in the lower end position, it abuts against the upper end of the connecting column 10. When the valve core plate 9 is in the upper end position, it abuts against the upper end surface of the air storage chamber 1a.
[0025] In this embodiment, the end of the first horizontal plate 7 is provided with two lugs 7b, and the end of the second horizontal plate 8 is provided with a connecting part 8a rotatably connected between the two lugs 7b.

Under the action of the limiting protrusion 8b and the vertical limiting groove 7c, the second horizontal plate 8 can only be flipped downward from the horizontal position or flipped from the downward position to the horizontal position. When the second horizontal plate 8 is in the horizontal position, the limiting protrusion 8b abuts against the lower end of the vertical limiting groove 7c.
[0026] In this embodiment, the upper end of the body 1 is provided with a positioning slot 1c, and a positioning ball 14 is provided in the positioning slot 1c.

[0027] In this embodiment, the upper end of the second horizontal plate 8 is provided with an arc-shaped pressing groove 8d. The lower side of the end of the second horizontal plate 8 away from the first horizontal plate 7 is provided with an arc-shaped chamfer 8e.
[0028] The present invention also discloses a method for using the above-mentioned safe and accident-proof lighter, comprising the following steps;
[0029] When the lighter is needed, rotate the first horizontal plate 7 to be directly above the through hole 1b. The flame outlet 7a and the through hole 1b are in a coaxial position. The positioning ball 14 enters the first positioning hole 71 and positions the first horizontal plate 7 in the first position. The first horizontal plate 7 drives the threaded rod 6a to rotate through the vertical shaft 6. The threaded rod 6a drives the valve core plate 9 to move downward along the first vertical rod 10a and the second vertical rod 11. The valve core plate 9 drives the valve core rod 12 downward to open the lower end opening of the gas inlet pipe 2. At this time, the second horizontal plate 8 is directly above the pressing block 5. Press the second horizontal plate 8. The second horizontal plate 8 drives the pressing block 5 to move downward to press the electronic lighter 4. At the same time, it drives the gas outlet needle 2a of the valve control component to emit gas, so as to realize the ignition of the lighter.
[0030] When the lighter needs to be put away or put away, rotate the first horizontal plate 7 to be directly above the pressing block 5. The first horizontal plate 7 drives the threaded rod 6a to rotate in the opposite direction via the vertical shaft 6. The threaded rod 6a drives the valve core plate 9 to move upward along the first vertical rod 10a and the second vertical rod 11. The valve core plate 9 drives the valve core rod 12 to close the lower opening of the air inlet pipe 2. At this time, the second horizontal plate 8 is directly above the through hole 1b, blocking the through hole 1b. The positioning ball 14 enters the second positioning hole 72 and positions the first horizontal plate 7 in the second position. Here, rotating the first horizontal plate 7 directly above the pressing block 5 can effectively prevent the pressing block 5 from being accidentally moved downward. The valve core rod 12 of the valve core assembly closes the lower opening of the air inlet pipe 2 to prevent the gas in the gas storage chamber 1a from flowing out through the valve control assembly when the pressing block 5 moves downward. The second horizontal plate 8 is directly above the through hole 1b, blocking the through hole 1b to prevent dust from entering the through hole 1b.
