The ignition device 3 comprises an ignition needle 31 and an ignition switch 32, wherein the ignition needle 31 is arranged vertically and comprises an electrode needle 311 and a ceramic tube 312 sleeved outside the electrode needle 311. The base 1 is in the shape of a round basin, and the burner 2 is arranged in the base 1 along the central axis direction of the base 1, and a hollow hole is provided on the bottom wall of the base 1. Further, a first positioning component for positioning the lower end of the ceramic tube 312 is arranged on the inner bottom surface of the base 1, and the ignition switch 32 is detachably installed in the base 1 and the operating part 320 of the ignition switch 32 is exposed outside the base 1, and the lower end of the ceramic tube 312 abuts against the inner side end of the ignition switch 32 so that the two are positioned relative to each other.

[0028] As can be seen from the above, in the utility model, a hollow hole is provided on the bottom wall of the base 1, so that the weight of the base 1 can be greatly reduced in combination with the thickness design of the base 1, which is conducive to achieving lightweight. At the same time, by providing the hollow hole, on the one hand, air can be added for the combustion of the stove head 2, and on the other hand, heat can be prevented from accumulating inside the base 1. Further, the ignition needle 31 and the ignition switch 32 are both installed on the base 1 in a detachable manner, so that the ignition needle 31 and the ignition switch 32 can be removed respectively when carrying, and then installed on the base 1 when using, so as to further achieve the lightweight of the camping stove. In addition, the lower end of the ceramic tube 312 is positioned by the first positioning component, and at the same time, the lower end of the ceramic tube 312 is abutted against the inner end of the ignition switch 32 to position the two relative to each other, so as to facilitate the stable installation of the ignition needle 31 and the ignition switch 32 on the base 1.

[0029] Preferably, the ignition switch 32 is in the shape of a long block and is installed on the inner bottom surface of the base 1 in the horizontal direction. The lower end of the ceramic tube 312 is bent toward one side and extends horizontally to form an extension portion 3121, the extension direction of the extension portion 3121 is perpendicular to the extension direction of the ignition switch 32, and the free end of the extension portion 3121 abuts against one side of the inner end of the ignition switch 32. Thereby, the ceramic tube 312 can be better positioned with the ignition switch 32, and the ignition needle 31 and the ignition switch 32 can be further ensured to be firmly installed on the base 1. Further preferably, in this embodiment, a positioning column 321 is convexly provided on one side of the inner end of the ignition switch 32, and the positioning column 321 extends along the length direction of the extension portion 3121 and is inserted into the opening of the extension portion 3121.

The first positioning block 51 can realize horizontal positioning of the inner end of the ignition switch 32, and the second positioning blocks 52 can realize left and right positioning of the outer end of the ignition switch 32, so that the ignition switch 32 can be more stably installed on the base 1 to avoid displacement during use.

[0032] Furthermore, the bottom wall of the base 1 is raised downward and at least three legs 13 are formed at the bottom of the base 1, wherein the side wall of one of the legs 13 on the side of the mounting surface 10 is the positioning wall 61 of the first positioning assembly, and the first positioning assembly also includes a positioning rib 62 protruding from the mounting surface 10. The positioning wall 61 extends along the length direction of the extension 3121 and abuts against the corresponding side of the extension 3121, while the positioning rib 62 is located on the other side of the extension 3121 and abuts against the lower end of the ceramic tube 312. In this way, the bottom can be placed stably by setting the legs 13, and the ignition needle 31 can be stably set in the base 1 by the mutual positioning of the first positioning assembly and the ignition switch 32.

[0033] Furthermore, the above-mentioned hollow holes include a first hollow hole 11, and there are at least two of the first hollow holes 11, and each first hollow hole 11 is respectively arranged between two connected legs 13, and is opened along the extension direction of the bottom wall of the base 1 between the two legs 13. In this way, while ensuring the firmness of the internal structure of the base 1, the opening area of ​​each first hollow hole 11 can be as large as possible, so that the lightweight of the base 1 can be better achieved. Further, the above-mentioned hollow holes also include a second hollow hole 12, and the second hollow hole 12 corresponds to the above-mentioned legs 13 one by one, and is respectively opened on the side wall of the base 1 corresponding to each leg 13. In this way, while ensuring the firmness of the internal structure of the base 1, the opening area on the base 1 can be further expanded, and the lightweight of the base 1 can be further achieved.

[0034] Furthermore, a pot support 7 is mounted on the base 1, and the pot support 7 is in the shape of a disc, and the bottom wall cover of the pot support 7 is arranged on the opening of the base 1, and the upper end of the burner 2 is arranged in the center of the bottom wall, and the bottom wall is provided with a mounting hole 71 for the upper end of the ignition needle 31 to pass through, and at least one notch 72 concave from top to bottom is provided on the side wall of the pot support 7. Thus, the upper positioning of the ignition needle 31 can be achieved, and the stable installation of the ignition needle 31 on the base 1 can be ensured. At the same time, by providing the notch 72, the influence of heat accumulation on the structure of the pot support 7 during use can be avoided, and the service life of the pot support 7 can be extended.

[0035] Furthermore, when the lightweight camping stove in the utility model is used, the energy-gathering pot 8 can be placed on the pot support 7. The energy-gathering pot 8 includes a pot body 81 and a pot cover 82 covering the opening of the pot body 81.
