[0022] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0023] As shown in the figure, a fuel lighter comprises a lighter body 1, wherein the lighter body 1 is provided with a accommodating cavity and an oil bottle 5 arranged in the accommodating cavity, the upper end of the oil bottle 5 is provided with a pipe joint 6 which is inserted into the oil bottle 5 and seals with the oil bottle 5, the lower end of the lighter body 1 is provided with an openable bottom cover 4, the upper end of the lighter body is provided with an ignition portion 17 adapted to the pipe joint, the oil bottle is located directly below the ignition portion 17, and the bottom cover 4 and the pipe joint 6 cooperate to clamp the oil bottle 5; the technical scheme is to set the bottom cover and the lighter body into a detachable structure, and the ignition portion and the oil bottle are in the same straight line, so that the oil bottle can be directly taken out of the lighter body after the bottom cover and the lighter body are separated, and then after the oil bottle is replaced, the oil bottle is put back into the lighter body, and the bottom cover and the ignition portion cooperate to clamp the oil bottle and the pipe joint, so it has the advantages of simple structure and convenient disassembly and assembly.

[0024] The bottom cover of the technical solution has two embodiments;

[0025] Embodiment 1: The inner bottom surface of the bottom cover 4 is provided with a top column 9 which contacts and cooperates with the bottom of the oil bottle 5; the top column is in hard contact with the bottom of the oil bottle, and the top column cooperates with the ignition frame to clamp the oil bottle.

[0026] Embodiment 2: A first elastic member 22 is provided between the inner bottom surface of the bottom cover 4 and the bottom of the oil bottle 5 to elastically abut against the two. A positioning column 23 is provided on the inner bottom surface of the bottom cover 4 for installing the first elastic member 22. The first elastic member adopts a spring and provides elastic pressure. The first elastic member and the ignition part cooperate to clamp the oil bottle.

[0027] Both the first embodiment and the second embodiment can achieve stable installation of the oil bottle, the difference being that one is hard contact and the other is elastic contact.

[0028] In addition, the bottom cover installation method of the present technical solution also has two embodiments;

[0029] Embodiment three: The lighter body 1 includes a top cover 3, an ignition frame 2 with the ignition part 17, and a bracket 13 for installing the top cover and the ignition frame 2. The bottom of the lighter body 1 is provided with a plurality of positioning protrusions 10 adapted to the bottom cover. A fastener connecting the bottom cover 4 and the bracket 13 is provided between the two. The fastener can be a screw. When disassembling, the bottom cover is removed first by removing the screws between the bottom cover and the bracket, and then the oil bottle can be conveniently replaced.

[0030] Embodiment 4: The bottom cover 4 is provided with a slider 18 which is slidably installed and plugged into the side wall of the lighter body 1. The side wall of the lighter body is provided with a slot 19 corresponding to the slider 18. The slider 18 is provided with a force-bearing portion 20 exposed at the bottom of the bottom cover 4. A second elastic member 21 is provided between the slider 18 and the bottom cover 4 to abut against the two. The force-bearing portion has anti-slip patterns. By pressing the force-bearing portion with a fingernail, the slider overcomes the elastic pre-tightening force of the second elastic member and withdraws from the slot, thereby realizing the separation of the lighter body and the bottom cover. After that, the oil bottle can be easily replaced.

[0031] In addition, there is another embodiment in which the bottom cover is partially opened. The principle is similar to that of the fourth embodiment. The bottom cover is fixed to the bottom of the lighter body, and only the area where the slider is configured can be opened. This area is hingedly mounted on the bottom cover.

[0032] The ignition part 17 is provided with a through hole 7 for the top end of the pipe joint 6 to pass through, and an interference fit or a clearance fit is adopted between the through hole and the pipe joint. The pipe joint 6 is provided with an annular boss 8 which contacts and cooperates with the lower bottom wall of the ignition part 17; after the bottom cover is installed on the bottom of the lighter body, the bottom cover will push the bottom of the oil bottle so that the annular boss at the upper end is close to the lower bottom wall of the ignition frame, thereby maintaining the stability of the oil bottle.

[0033] When removing the oil bottle, if the through hole and the pipe joint are clearance fit, the pipe joint will be removed along with the oil bottle, and then the pipe joint and the oil bottle will be manually separated to add oil; if the through hole and the pipe joint are interference fit, the pipe joint will remain in the through hole, and only the oil bottle will be removed. After the fuel is added, align it with the cotton core and insert it back into the pipe joint.

[0034] The side wall of the lighter body 1 corresponding to the oil bottle 5 is provided with a viewing window 11, through which the amount of oil in the oil bottle can be observed.

[0035] A sealing ring 12 is arranged between the end of the pipe joint 6 inserted into the oil bottle 5 and the oil bottle 5, which has the advantage of good sealing performance.

[0036] The pipe joint 6 is provided with a cotton core 16 connecting the oil bottle 5 and the outside; the arc head corresponds to the cotton core.

[0037] The lighter of the present technical solution can be applied to an electric arc fuel lighter or a flint fuel lighter. In the electric arc fuel lighter, a battery 14 is installed in the bracket 13 , and an arc head 15 connected to the battery 14 is provided in the ignition frame 2 .
