A flange extending outward in the circumferential direction is further provided on the outer side wall of the upper sleeve, and the upper end surface of the flange is flush with the upper end surface of the upper sleeve.

[0004] The conventional shunt channels are strip-shaped grooves extending in the up-and-down direction. Since the number of strip-shaped grooves is large, they are thin and all provided on the upper sleeve, and the volume of the upper sleeve is small, the dimensions of the processed strip-shaped grooves are relatively limited and small, and the processing difficulty is large, resulting in low production efficiency and a certain defective rate. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an air outlet mechanism of a spark ignition gasification furnace, which is convenient for processing and helps to improve production efficiency and the qualified rate.

Detailed Description of the Embodiment

[0027] The present invention will be further described in detail below in conjunction with the embodiments of the drawings.

[0028] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] Embodiment 1: As Figures 1 to 3 shown, an air outlet mechanism of a lighter gasification furnace includes a mounting base 1 and a mounting head 2. An installation groove 11 is provided at the upper end of the mounting base 1, and an air inlet hole 12 is provided at the bottom of the installation groove 11. The mounting head 2 is inserted and matched with the installation groove 11. A plurality of first grooves 13 distributed along the circumferential direction are provided on the installation groove 11, and a plurality of second grooves 21 distributed along the circumferential direction are provided on the mounting head 2. The plurality of first grooves 13 correspond to the plurality of second grooves 21 one by one. The first groove 13 and the corresponding second groove 21 cooperate to form a first air outlet hole 3 extending obliquely upward, and the lower end of the first air outlet hole 3 is communicated with the air inlet hole 12.

[0030] In this embodiment, the first groove 13 is provided on the side surface of the installation groove 11, the upper end of the first groove 13 penetrates the upper end surface of the mounting base 1, the second groove 21 is provided on the outer side surface of the mounting head 2, and the lower end of the second groove 21 penetrates the lower end surface of the mounting head 2.

[0031] In this embodiment, the cross-section of the installation groove 11 is circular, elliptical, polygonal or other irregular shapes.

[0032] During assembly, the mounting base 1 and the mounting head 2 are fitted together by inlaying, so that the first groove 13 and the corresponding second groove 21 cooperate to form a first air outlet hole 3 extending obliquely upward, and then it is installed at the inner bottom surface of the ceramic cup 5. A combustion chamber is formed inside the ceramic cup 5. The lower end of the mounting base 1 extends out of the ceramic cup 5 and is connected to the air mixing pipe 6.

[0033] It should be noted that this structure is the air outlet mechanism of a windproof lighter gasification furnace.

[0034] Embodiment 2: As Figure 2 and Figure 3 shown, the rest is the same as that of Embodiment 1. The difference is that a plurality of notches 14 are provided on the upper edge of the outer side surface of the mounting base 1. The plurality of notches 14 correspond to the plurality of first grooves 13 one by one, and the notches 14 are communicated with the corresponding first grooves 13. The setting of the notches 14 helps to enlarge the size of the air outlet end of the first air outlet hole 3, so that the flowing mixed gas can be more evenly diffused into the ceramic cup 5, which helps to improve the ignition rate.

[0035] Example 3: As Figures 1 to 3 shown, the rest is the same as in Example 1, and the difference is that an air storage chamber 4 is formed between the lower end surface of the mounting head 2 and the bottom of the mounting groove 11. The lower end of the first air outlet hole 3 and the upper end of the air inlet hole 12 are respectively communicated with the air storage chamber 4. The air storage chamber 4 can balance the air pressure to ensure a stable pressure and flow rate when the mixed gas is ejected, so that the formed flame is more stable when ignited and is not prone to sudden changes in size, which helps to improve the use experience of the lighter.

[0036] In this embodiment, at least one positioning block 22 is fixedly arranged on the side surface of the mounting head 2. The lower end surface of the positioning block 22 abuts against the upper end surface of the mounting base 1. The setting of the positioning block 22 can accurately assemble the relative positions of the mounting head 2 and the mounting base 1, so as to ensure the consistency of the size and shape of the air storage chamber 4 during the assembly process, reduce deviations, and at the same time help to improve the assembly efficiency. Preferably, a plurality of positioning blocks 22 are provided, and the plurality of positioning blocks 22 are distributed along the circumferential direction. A positioning block 22 is arranged between two adjacent second grooves 21. The positioning block 22 can prevent the roots of the two beams of mixed gas ejected from two adjacent first air outlet holes 3 from sticking together to ensure the ignition rate of the lighter.

[0037] Example 4: As Figures 4 to 6 shown, the rest is the same as in Example 1, and the difference is that a second air outlet hole 23 is provided in the center of the mounting head 2. The second air outlet hole 23 and the air inlet hole 12 are on the same axis, and the diameter of the second air outlet hole 23 is smaller than the diameter of the air inlet hole 12, so as to prevent the mixed gas flowing in from the air inlet hole 12 from directly spraying into the ceramic cup 5 through the second air outlet hole 23, and ensure that part of the mixed gas can be sprayed into the ceramic cup 5 through the first air outlet hole 3.

[0038] It should be noted that this structure is the air outlet mechanism of the direct-injection lighter gasifier. At this time, the mixed gas sprayed into the ceramic cup 5 through the second air outlet hole 23 forms a main flame after ignition, and the mixed gas sprayed into the ceramic cup 5 through the first air outlet hole 3 forms an auxiliary combustion flame after ignition.

[0039] Example 5: As Figure 1 and Figure 2 shown, the rest is the same as in Example 1 or Example 4, and the difference is that a first inclined surface 24 that slopes downward from the inside to the outside is provided on the upper end surface of the mounting head 2. The upper end surface of the mounting head 2 is not easy to accumulate dust and affect ignition, and has good stability.

[0040] Example 6: As Figure 4 and Figure 5As shown, the rest is the same as in the fourth embodiment, except that a boss 25 is fixedly arranged at the upper end of the mounting head 2, the upper end of the second air outlet 23 penetrates through the boss 25, and the side surface of the boss 25 is a second inclined surface 251 that slopes from the inside to the outside and downwards. The setting of the boss 25 can prevent the mixed gas ejected from the first air outlet 3 from bonding with the mixed gas ejected from the second air outlet 23, and the formed flame is relatively full when ignited.

[0041] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the implementation of the present invention is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
