DETAILED DESCRIPTION

[0029] The utility model will be described further in detail below in combination with the embodiment of the drawings.

[0030] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "inner", "outer" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, a particular orientation and operation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0031] Embodiment one: as shown in Figure 2 and Figure 3 , a porcelain cup, including the cup body 1 that is flat, the inside of cup body 1 forms combustion chamber 11, the upper end surface of cup body 1 is fixedly provided with the extension cylinder 2 that communicates with combustion chamber 11, the outer diameter of extension cylinder 2 is less than the outer diameter of cup body 1 in the same direction, and the stepped surface 12 around extension cylinder 2 is formed between cup body 1 and extension cylinder 2.

[0032] In the embodiment, the extension cylinder 2 is integrally formed with the cup body 1 or assembled with the cup body 1, and is preferably integrally formed, that is, the extension cylinder 2 and the cup body 1 are both made of ceramic material.

[0033] In the embodiment, the cross section of the combustion chamber 11 is in an oval shape or a polygonal shape, for example, an octagonal shape, as shown in Figure 4 .

[0034] In the technical solution, the outer diameter of the extension cylinder 2 is smaller than the outer diameter of the cup body 1 in the same direction, that is, the size of the upper part of the porcelain cup is small, and at this time, the fire outlet 51 of the air baffle 5 can be designed to be smaller, and the design size of the air baffle 5 can also be reduced (see Figure 5 ), which helps to reduce the thickness of the lighter, and further reduces the overall volume of the lighter, facilitating carrying.

[0035] In addition, when the combustion head 6 with oblique upward air outlet is matched (see Figure 5 ), the mixed gas flows obliquely upward into the combustion chamber 11, and the conventional combustion chamber 11 is relatively low, so that the mixed gas may hit the upper edge of the porcelain cup, and it is difficult to achieve good gas gathering effect, which is not conducive to ensuring the ignition rate. The technical solution adds the extension cylinder 2, the internal cooperation of the combustion chamber 11 and the extension cylinder 2 forms a longer space, the gas gathering effect is better, and the combustion head 6 with oblique upward air outlet can be matched, which helps to ensure the ignition rate.

[0036] Embodiment two: as shown in Figure 3 , the rest is the same as embodiment one, and the difference is that the cross section of the inner hole of the extension cylinder 2 and the cross section of the combustion chamber 11 are the same shape.

[0037] Further, the inner diameter of the extension cylinder 2 is equal to the inner diameter of the combustion chamber 11 in the same direction, facilitating processing and production.

[0038] Embodiment three: as shown in Figure 3 , Figure 5 and Figure 6 , the rest is the same as embodiment one, and the difference is that the lower end surface of the cup body 1 is provided with a perforation 13 and an insulating part 3, the perforation 13 is communicated with the combustion chamber 11, and the insulating part 3 is used to prevent the current from breaking through the air between the air baffle 5 and the air mixing pipe 7. The perforation 13 is a conventional structure, and the combustion head 6 is connected with the air mixing pipe 7 after penetrating the perforation 13.

[0039] After the extension tube 2 is installed, the combustion chamber 11 and the interior of the extension tube 2 form a longer space, resulting in a longer ignition distance. Without the insulation component 3, the current generated by the ignition assembly may break through the air between the wind shroud 5 and the air mixing pipe 7, or the air between the iron cup 4 and the air mixing pipe 7, without passing through the combustion chamber 11 to ignite the gas mixture. By installing the insulation component 3, the current can be prevented from breaking through the air between the wind shroud 5 and the air mixing pipe 7. At the same time, the installation of the insulation component 3 can also increase the overall length of the cup body 1, thereby extending the distance between the iron cup 4 and the air mixing pipe 7. This distance is ensured to be greater than the ignition distance, preventing the current from breaking through the air between the iron cup 4 and the air mixing pipe 7. Ultimately, this ensures that the current can only pass through the combustion chamber 11 to ignite the gas mixture, which helps to guarantee the ignition rate.

[0040] Example 4: Figure 7 As shown, the rest is the same as in Embodiment 3, except that the insulating component 3 includes two insulating partitions 31, which are distributed on both sides of the perforation 13 and are located along the short axis of the cup body 1. Preferably, the insulating partitions 31 are integrally formed with the cup body 1, that is, the insulating partitions 31 are made of ceramic material.

[0041] Example 5: Figure 6 As shown, the rest is the same as in Embodiment 3, except that the insulating element 3 is an insulating convex ring 32, which surrounds the through hole 13. Preferably, the convex ring 32 is integrally formed with the cup body 1, that is, the convex ring 32 is made of ceramic material.

[0042] Example 6: Figure 8 to Figure 10 As shown, a lighter gasifier includes an iron cup 4 and a ceramic cup of any one of Embodiments 1 to 5. The iron cup 4 includes a first sleeve 41, a connecting ring 42, a second sleeve 43, and a pressure ring 44 connected sequentially from bottom to top. The first sleeve 41 is fitted onto the outside of the cup body 1, the connecting ring 42 abuts against the stepped surface 12, the second sleeve 43 is fitted onto the outside of the extension tube 2, and the pressure ring 44 is located directly above the extension tube 2. Furthermore, a conductive ring 8 is provided between the pressure ring 44 and the extension tube 2, and the inner wall of the conductive ring 8 is provided with inwardly extending conductive needles 81.

[0043] In this technical solution, the step surface 12 is either a plane or an inclined surface that slopes downward from the inside out. The inclined surface can serve as a guide and facilitate personnel assembly. Correspondingly, the iron cup 4 is compatible with the porcelain cup to ensure that the iron cup 4 and the porcelain cup fit tightly together, which helps to improve the stability of the structure.

[0044] Typically, a burner head 6 is installed inside the cup body 1, and a perforation 13 is provided at the lower end of the burner head 6 (see...). Figure 6 It is then connected to the air mixing pipe 7.

[0045] The utility model has carried on the exemplary description above binding the drawing, obviously the implementation of the utility model is not limited by above-mentioned mode, as long as various improvements of method conception and technical scheme that have adopted the utility model or the conception and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
