DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with embodiments and drawings.

[0027] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0028] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1-2 A large flame lighter shown in the figure comprises a shell 2, a main body 3 slidably arranged in the shell 2 and a head cover 1, the sliding protrusion 301 of the main body 3 passes through the shell 1 from the stroke groove 202, the push portion 11 of the head cover 1 is rotatably connected to the main body 3, and a snap-fit ​​assembly is arranged at one end of the head cover 1 away from the push portion 11, the snap-fit ​​assembly comprises a second elastic member 15 and a limiting body 16 installed in the mounting cavity 101 of the head cover 1. In the present embodiment, the second elastic member 15 is a spring and the limiting body 16 is a sphere. Those skilled in the art may also set the limiting body 16 to a block with an arc surface or a triangular or trapezoidal cross-section and a guide inclined surface, so that it can gradually retract into the mounting cavity 101 under the push action of the inner wall of the shell 2.

[0031] A positioning hole 201 is formed in the shell 2 at a position corresponding to the limiting body 16, and a torsion spring is arranged between the head cover 1 and the main body 3. When the main body 3 is retracted into the shell 2, the limiting body 16 is located in the positioning hole 201 at the lower limit of the push of the second elastic member 15. When the user pushes the sliding protrusion 301 from the outside to slide in the travel groove 202 and thereby causes the main body 3 and the head cover 1 to slide relative to the shell 2, the limiting body 16 is retracted into the installation cavity 101 and moves upward under the pressure of the inner wall of the shell 2 until the head cover 1 drives the limiting body 16 to move out of the upper opening of the shell 2. At this time, the torsion spring drives the head cover 1 to flip relative to the main body 3, and the head cover 1 is opened to expose the ignition cavity 102.

[0032] The main body 3 has a gas storage structure, a gas outlet structure, and an ignition structure. The gas outlet structure includes a gas distribution chamber 42. The gas distribution chamber 42 has an air inlet channel 41 connected to the gas storage structure and an air outlet 51 matched with the ignition structure, and the air inlet channel 41 is connected to a plurality of air outlets 51 at the same time through the gas distribution chamber 42; the air inlet channel 41 is arranged on the bottom plate formed by the middle frame 4, and the air outlet 51 is arranged on the distribution plate 5 buckled with the bottom plate, and a gas distribution chamber 42 is formed between the bottom plate and the distribution plate 5; the plurality of air outlets 51 are linearly arranged or arranged on the distribution plate 5 to form a geometric pattern (for example, an arc, a triangle, etc.).

[0033] Furthermore, the plurality of gas outlets 51 in this embodiment are arranged linearly on the distribution plate 5 and include six gas outlets 51 arranged at intervals to ensure the formation of a linear flame.

[0034] like Figure 3-8 As shown, the bottom plate and the distribution plate 5 are separately arranged, and the bottom plate and the distribution plate 5 are buckled together up and down to form a gas distribution chamber 42 therebetween, a first positioning groove 43 is arranged on the surface of the bottom plate, and a first positioning protrusion 52 is arranged on the lower end surface of the distribution plate 5, a sealing ring is embedded in the first positioning groove 43, and the bottom plate and the distribution plate 5 are buckled together up and down to make the first positioning protrusion 52 located above the sealing ring and limit the sealing ring.

[0035] The bottom plate is integrated with the middle frame 4 of the lighter, the air inlet channel 41 is connected to the gas valve 7 of the gas storage structure, and the middle frame 4 also includes a support portion 46 arranged on the side of the bottom plate, and the support portion 46 limits the side of the distribution plate 5. The distribution plate 5 includes a first positioning protrusion 52 extending from its lower end surface, and the first positioning protrusion 52 is embedded in the positioning cavity 461 formed by the support portion 46, and a side of the first positioning protrusion 52 close to the bottom plate is provided with a slot 53 connected to a plurality of gas outlets 51, and the slot 53 cooperates with the bottom plate to form a gas distribution cavity 42, that is, the air inlet channel on the bottom plate, the slot on the first positioning protrusion, and the plurality of gas outlets 51 on the distribution plate are connected to form a gas path for gas distribution.

[0036] The inner wall of the support portion 46 is provided with a second positioning protrusion 44, and the distribution plate 5 has a second positioning groove 54 that cooperates with the second positioning protrusion 44. The ignition structure includes a micro switch located below the middle frame 4, and a through hole is provided on the second positioning protrusion 44. The ignition needle of the micro switch passes through the through hole to the top of the gas outlet 51 to facilitate ignition.

[0037] Regarding the micro switch, when the head cover 1 and the main body 3 are located inside the shell 2, the bottom of the main body 3 abuts against the bottom of the shell 2 so that the pressing part of the micro switch abuts against the inner wall of the bottom of the shell 2 and remains closed. When the main body 3 slides and drives the head cover 1 to expose the shell 2, the bottom of the main body 3 moves away from the bottom of the shell 2, causing the pressing part of the micro switch to pop out, causing the ignition needle to ignite.

[0038] When the user pushes the sliding protrusion 301 to Fig. 9When in the position shown, the head cover 1 is flipped open relative to the main body 3 under the drive of the torsion spring, driving the push part 11 to rotate and press the transmission part 12 downward, and the transmission part 12 further presses the movable end of the seesaw 6 to make the seesaw 6 tilt up to open the air valve 7, connect the air path from the air storage structure to the air intake channel 41, and at the same time turn on the micro switch for ignition; the movable end of the seesaw 6 is equipped with a first elastic member 14, and the first elastic member 14 pushes the movable end of the seesaw 6 when the head cover 1 is closed relative to the main body 3 (the transmission part 12 moves up), so that the seesaw 6 is reset and the air valve 7 is closed. At this time, the head cover 1 and the main body 3 are completely retracted into the shell 2, and the pressing part of the micro switch is against the inner wall of the bottom of the shell 2 to keep it closed.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
