In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0027] Embodiment 1: As Figures 1 to 4 shown, an air outlet head of a lighter includes a valve 1. A main air hole 11 and at least one auxiliary air hole 12 are provided on the valve 1. The intake end of the auxiliary air hole 12 is communicated with the main air hole 11. Among them, the main air hole 11 extends in the up and down direction and penetrates through the upper and lower ends of the valve 1. Preferably, at least two auxiliary air holes 12 are provided, and all the auxiliary air holes 12 are equidistantly distributed in the circumferential direction. The setting of the multiple auxiliary air holes 12 helps to improve the uniformity of the distribution of the combustion-supporting mixed gas.
[0028] In this embodiment, the valve 1 includes a first section 13, a second section 14, a third section 15, and a fourth section 16 connected in sequence from bottom to top. The first section 13 is used for insertion and cooperation with the heat insulation cup 2. The outer diameter of the second section 14 is larger than that of the third section 15, and a step structure is formed between the second section 14 and the third section 15. The outlet end of the auxiliary air hole 12 is communicated with the outer side surface of the second section 14. An outer convex ring 161 is provided on the outer side surface of the fourth section 16, and a plurality of diversion channels 162 distributed in the circumferential direction are provided on the outer convex ring 161. Preferably, the diversion channels 162 are equidistantly distributed in the circumferential direction, which helps to further improve the uniformity of the distribution of the combustion-supporting mixed gas.
[0029] In this embodiment, the auxiliary air hole 12 is in a flared shape, which helps the flowing combustion-supporting mixed gas to quickly diffuse.
[0030] Embodiment 2: As Figures 1 to 3 shown, the rest is the same as that of Embodiment 1, and the difference is that a plurality of convex ribs 163 distributed in the circumferential direction are fixedly provided on the outer side surface of the outer convex ring 161, and a diversion channel 162 is formed between two adjacent convex ribs 163. Preferably, the convex ribs 163 and the outer convex ring 161 are integrally formed. Of course, the diversion channel 162 can also be a through hole opened on the outer convex ring 161, and the through hole penetrates through the upper and lower end surfaces of the outer convex ring 161.
[0031] In this embodiment, the outer convex ring 161 and the fourth section 16 are integrally formed, which helps to simplify the processing technology, reduce the production cost, and improve the production efficiency.
[0032] Embodiment 3: As Figure 1 、Figure 3 and Figure 4 As shown in Figure 4 , the rest is the same as that of the first embodiment, except that a first cutting surface 141 with the same number as the auxiliary air holes 12 is provided on the outer side of the second section 14. The first cutting surfaces 141 correspond to the auxiliary air holes 12 one by one, and the air outlet ends of the auxiliary air holes 12 are communicated with the corresponding first cutting surfaces 141. The design of the first cutting surface 141 helps to increase the distance between the second section 14 and the heat insulation cup 2 and shorten the length of the auxiliary air holes 12, so that the combustion-supporting mixed gas flowing through the auxiliary air holes 12 can be more fully diffused, which helps to improve the uniformity of the distribution of the combustion-supporting mixed gas.
[0033] Furthermore, a second cutting surface 151 with the same number as the first cutting surfaces 141 is provided on the outer side of the third section 15. The second cutting surfaces 151 correspond to the first cutting surfaces 141 one by one, and the second cutting surfaces 151 are coplanar with the corresponding first cutting surfaces 141, which avoids the formation of a step between the first cutting surface 141 and the third section 15 and affects the flow direction and distribution of the combustion-supporting mixed gas. At the same time, it also helps to increase the distance between the third section 15 and the heat insulation cup 2, and the design is more reasonable.
[0034] Embodiment 4: As shown in Figure 1 and Figure 3 As shown in Figure 3 , the rest is the same as that of the third embodiment, except that the second cutting surface 151 and the corresponding first cutting surface 141 form a cutting plane, and a drainage groove 17 is provided on the cutting plane. The lower end of the drainage groove 17 is communicated with the auxiliary air hole 12, and the bottom of the drainage groove 17 is inclined from bottom to top and outward. Part of the combustion-supporting mixed gas flowing through the auxiliary air hole 12 can flow rapidly obliquely upward along the drainage groove 17. This part of the combustion-supporting mixed gas is faster and can quickly flow into the combustion chamber to ensure that there is continuously sufficient combustion-supporting mixed gas in the combustion chamber for ignition to form a combustion-supporting flame, which helps to improve the stability of the ignited flame and the flame is not easy to shake.
[0035] Embodiment 5: As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, an air outlet mechanism includes an insulation cup 2, an air mixing tube 3, an iron cup 4 and any one of the air outlet heads of the first to fourth embodiments. The bottom of the insulation cup 2 is provided with a mounting hole 21, the first section 13 of the valve 1 is provided with the mounting hole 21 and is connected to the upper end of the air mixing tube 3, the second section 14, the third section 15 and the fourth section 16 of the valve 1 are all located in the insulation cup 2, the middle of the air mixing tube 3 is provided with an air inlet 31, the lower part of the air mixing tube 3 is provided with a boosting cavity 32, the boosting cavity 32 is provided with a boosting sheet 33, a sealing ring 34, a filter 35 and a rubber tail cap 36 from top to bottom, and the iron cup 4 is sleeved on the insulation cup 2. Among them, the insulation cup 2 is a ceramic cup, and the area above the valve 1 in the insulation cup 2 is a combustion chamber. After the mixed gas is ignited, flames will be formed in the combustion chamber and the area above the insulation cup 2.
[0036] In this embodiment, the inner wall of the heat-insulating cup 2 is provided with a first inner ring 22, a second inner ring 23, and a third inner ring 24, which are distributed from bottom to top. The inner diameters of the first inner ring 22, the second inner ring 23, and the third inner ring 24 increase in sequence. The first section 13 of the valve 1 is fixedly provided with a positioning ring 131 located inside the first inner ring 22. The positioning ring 131 abuts against the inner bottom surface of the heat-insulating cup 2. An air storage chamber 5 is formed between the second inner ring 23 and the valve 1. The outlet end of the auxiliary air hole 12 is connected to the air storage chamber 5. The air storage chamber 5 helps to distribute the combustion-supporting mixed gas more evenly. Preferably, the positioning ring 131 is integrally formed with the first section 13 of the valve 1.
[0037] In this embodiment, the outer convex ring 161 is located inside the third inner ring 24 .
[0038] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
