Embodiment one:
As shown in fig. 1, the lighter combustion head of the present embodiment mainly includes: porcelain cup 1, metal sleeve 3 and air outlet part 2. Wherein, the inner wall of the porcelain cup 1 is provided with an inner extension section 1-2. The metal sleeve 3 is provided with a lower limit part 3-3, and the lower limit part 3-3 is of a lower limit structure after the porcelain cup 1 is assembled. And the top of the metal sleeve 3 is turned outwards to form a flange 3-1, and a groove 3-4 is formed between the flange 3-1 and the lower limit part 3-3 in a surrounding manner. The inward extending section 1-2 on the porcelain cup 1 is arranged in the groove 3-4, the flange 3-1 and the lower limiting part 3-3 limit the inward extending section 1-2 in the groove 3-4, namely, the lower part of the inward extending section 1-2 on the porcelain cup 1 is limited by the lower limiting part 3-3, and the upper part is limited by the flange 3-1, so that the porcelain cup 1 is ensured not to be separated from the metal sleeve 3. Because the porcelain cup 1 is a hard and brittle material, the porcelain cup is easy to be broken or broken when being strongly extruded or pressed, and the plasticity of metal is much better than that of porcelain, after the porcelain cup 1 is arranged on the metal sleeve 3, the flange 3-1 is formed by outwards flanging the top of the metal sleeve 3, so that the inward extension section 1-2 of the porcelain cup 1 is limited between the flange 3-1 and the lower limit, the assembly is simple, and the quality of the porcelain cup 1 can be ensured.
Specifically, after the inner extension section 1-2 is sleeved on the metal sleeve 3, the top of the metal sleeve 3 is turned outwards to form a flange 3-1 of the metal sleeve, and the flange 3-1 and the lower limiting part 3-3 enclose a groove 3-4, so that the inner extension section 1-2 is limited in the groove 3-4. In the process, the groove 3-4 is formed after the flange 3-1 is formed by flanging in the later period, the structure of the groove 3-4 is not required to be processed in advance, and the manufacturing is simple. The flange 3-1 is an annular flange 3-1, the inner extension 1-2 is an annular inner extension 1-2, the annular flange 3-1 and the annular inner extension 1-2 are simple to mold, the most reliable connection between the porcelain cup 1 and the metal sleeve 3 is ensured, and the porcelain cup 1 is not easy to loose. In this embodiment, the inner extension 1-2 on the porcelain cup 1 abuts against the lower limit portion 3-3, and the flange 3-1 abuts against the inner extension 1-2, which is hard-connected, i.e. the porcelain cup 1 is fixed on the top of the metal sleeve 3. Or the inward extending section 1-2 on the porcelain cup 1 is movably propped against the lower limiting part 3-3 and the flange 3-1, namely, the porcelain cup 1 can move left and right or up and down relative to the metal sleeve 3 at the moment, the porcelain cup is in soft connection, and the two modes can meet the requirements, namely, the requirements on the manufacturing and assembling precision between the porcelain cup 1 and the metal sleeve 3 are low, and the assembly between the porcelain cup 1 and the metal sleeve 3 is simple.
In this embodiment, the flanging angle when the top of the metal sleeve 3 is turned outwards to form the flange 3-1 is smaller than 90 degrees, specifically, the flanging angle when the top of the metal sleeve 3 is turned outwards to form the flange 3-1 is optimally between 30 degrees and 60 degrees, which ensures that the flange 3-1 can form an upper limit on the inward extending section 1-2 of the porcelain cup 1 and can also ensure that the process is easy to realize when the flange is formed into the flange 3-1, because when the flanging angle is too large, the metal sleeve 3 is easy to crack due to too large plastic deformation, and when the flanging angle is too large, the requirement on the flanging tool is also relatively high. Wherein, the top of the inward extending section 1-2 of the porcelain cup 1 is provided with a first inclined plane 1-1, the top of the metal sleeve 3 is turned outwards to form a flange 3-1, and a second inclined plane is formed on the outer wall of the flange 3-1, and when the flange of the metal sleeve 3 forms the second inclined plane, the second inclined plane is stuck on the first inclined plane 1-1, so that the hard connection of the porcelain cup 1 and the metal sleeve 3 is realized. Or after the flanging forms a second inclined plane, the first inclined plane 1-1 and the second inclined plane are movably propped against each other to realize the flexible connection between the porcelain cup 1 and the metal sleeve 3. The provision of the first inclined surface 1-1 prevents interference of the flange 3-1 with the inward extension 1-2 of the porcelain cup 1 when the flange 3-1 is formed by flanging.
The air outlet component 2 of the embodiment is arranged in the porcelain cup 1 and the metal sleeve 3, the air outlet component 2 is inserted into the metal sleeve 3, the air outlet component 2 is provided with an air outlet hole 2-1, and the air outlet hole 2-1 is communicated with the metal sleeve 3. Specifically, an air inlet hole 3-2 is arranged on the metal sleeve 3, and an air outlet hole 2-1 is communicated with the air inlet hole 3-2.
Optionally, in this embodiment, a microporous sheet 4, an O-ring 5, a filter screen 6 and a sealing sleeve 7 are further disposed at the bottom of the metal sleeve 3 in sequence.
Embodiment two:
As shown in fig. 2, the lighter combustion head of the present embodiment is different from that of the first embodiment mainly in the difference of the air outlet member 2. The structure and the installation manner of the air outlet member 2 of the present embodiment are different from those of the first embodiment.
Specifically, the air outlet member 2 of the present embodiment is mounted in the porcelain cup 1 and the metal sleeve 3 by a bracket 8. Wherein, support 8 includes upper tube and down tube that links to each other, and the diameter of upper tube is greater than the diameter of down tube, and forms a step between upper tube and the down tube. The lower pipe is arranged in the metal sleeve 3 in a penetrating way, the step is propped against the inner extension section 1-2, the upper pipe is arranged in the porcelain cup 1, and the air outlet part 2 is arranged in the upper pipe. The air outlet component 2 is arranged in the metal sleeve 3 and the porcelain cup 1 through the bracket 8, so that the air outlet component 2 can be conveniently replaced and maintained.
In addition, in the embodiment, the air outlet component 2 is provided with a central air outlet hole 2-1 and a plurality of side air outlet holes 2-2, and the side air outlet holes 2-2 are arranged along the circumferential direction of the central air outlet hole 2-1.
Embodiment III:
As shown in fig. 3, in the lighter combustion head of the present embodiment, compared with the second embodiment, the bracket 8 is omitted, the air outlet member 2 of the present embodiment is directly mounted in the porcelain cup 1, and no connection relationship is formed between the air outlet member 2 and the metal sleeve 3.
In the three schemes of the utility model, the inner wall of the porcelain cup 1 is provided with the inward extending section 1-2, in the assembling process, when the porcelain cup 1 is placed on the metal sleeve 3, the top of the metal sleeve 3 is outwards turned to form the flange 3-1, so that the inward extending section 1-2 on the porcelain cup 1 is limited between the lower limiting part 3-3 and the flange 3-1, namely, the inward extending section 1-2 is limited in the groove 3-4, the porcelain cup 1 can move up and down or move left and right (soft connection) or can be fixed (hard connection) in the groove 3-4, the precision requirement is low, the assembling between the porcelain cup 1 and the metal sleeve 3 is simple, the connection stability is good, and the porcelain cup is not easy to fall off. The flange 3-1 at the top of the metal sleeve 3 is formed by flanging after the porcelain cup 1 is assembled, and after the flange 3-1 is formed by flanging, the flange 3-1 and the lower limit part 3-3 enclose a groove 3-4, so that the groove 3-4 structure does not need to be arranged in advance.
