Description

Technical Field

[0001] The utility model relates to the technical field of lighters, in particular to a four-piece assembly in a lighter. Background Art

[0002] The four parts of the existing lighters on the market include: a disc for adjusting the size of the flame (because most lighters use sponges as flame adjustment pieces, the flame adjustment pieces are also called sponges, followed by non-woven fabrics, constant flow valve pieces, etc.), a T-shaped sponge seat, an aluminum core sleeve, and a drainage core. In the past two decades of production, most sponges and T-shaped sponge seats are manually pressed into one body with a jig before leaving the factory, and the rest are loose parts. After being sold to lighter manufacturers, they are also manually loaded into the lighter three times in sequence using a jig. In this process, due to the small parts, many varieties, and complex structures, there are many jigs and assembly processes in the assembly process, resulting in a high scrap rate in production. This is because it is necessary to check whether the parts are missed, reversed, or upside down every time they are placed, especially the sponge and T-shaped sponge seat. After being placed, the head of the lighter is deep and small, and it is difficult for light to reach, making it difficult to observe, and the parts are small and difficult to place. In addition, it is difficult for workers who are paid by piecework in actual production to control the scrap rate. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a four-piece assembly in a lighter, which has a simple structure and is easy to install, can greatly reduce the difficulty of installation, improve production efficiency, and increase the yield.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A four-piece assembly in a lighter is provided, comprising:

[0006] A flame regulating plate, wherein a through hole is provided in the middle thereof;

[0007] A T-shaped sponge seat, the upper end of which can be inserted into the through hole;

[0008] A core sleeve, which is located at the lower end of the T-shaped sponge seat and is integrally formed with the T-shaped sponge seat;

[0009] A drainage core is installed in the inner cavity of the core sleeve.

[0010] Furthermore, the drainage core and the core sleeve are composite and integrated.

[0011] Furthermore, the drainage core can be inserted into the inner cavity of the core sleeve.

[0012] Specifically, the diameter of the upper end of the drainage core is slightly larger than the diameter of the lower end.

[0013] Furthermore, it also includes an extended trustee tube installed at the lower end of the core sleeve, and the extended trustee tube is integrally formed with the core sleeve.

[0014] Furthermore, a guide groove is provided on the side wall of the core sleeve, and the guide groove is communicated with the inner cavity of the core sleeve.

[0015] Furthermore, a guide groove is provided on the side wall of the core sleeve, and the guide groove is not communicated with the inner cavity of the core sleeve.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The four-piece assembly in the lighter of the utility model example, the T-shaped sponge seat and the core sleeve are integrally formed, and the original two-time stamping or upsetting of the T-shaped sponge seat and the core sleeve is improved to one-time stamping or upsetting, thereby improving production efficiency and reducing the generation of scraps. At the same time, the problem that the split parts are too small and too thin to be hot-formed by a die-casting machine is optimized. In addition, the installation process is also reduced during the installation process, making the installation simpler. It also avoids the problem of plastic in the middle of the original T-shaped sponge seat and the core sleeve when the drainage core is separately assembled due to the burrs and excessive thickness at the T-shaped big head of the drainage core produced separately. The plastic of the multi-microporous drainage core has good compressibility, which will change the flame of the lighter. That is, this structure does not force the drainage core, and will not affect the force of the flame adjustment plate;

[0018] 2. In the four-piece assembly of the lighter of the utility model, the drainage core and the core sleeve can be integrally formed. The original method of making the upper end of the drainage core into a T-shaped large head and then inserting it into the T-shaped inner cavity of the core sleeve to prevent the drainage core from falling off is changed to pre-embed the T-shaped sponge seat and the core sleeve composite body into a drainage core thermoforming mold to be thermoformed into one, which can also save production costs according to customer requirements, so that the structure does not need to be assisted by an extended trustee, and can also ensure that it is fixed and will not fall off;

[0019] 3. In the four-piece assembly of the lighter of the utility model, when the extended trustee portion is very short or zero, the upper end diameter of the drainage core is slightly larger than the lower end diameter to prevent it from falling off, and it is also beneficial for demoulding during production. In addition, it is also beneficial for reducing bending and breaking during transportation and automated production;

[0020] 4. In the four-piece assembly of the lighter of the utility model, the drainage core can be riveted with the core sleeve extension tube, so that the drainage core will not fall off, achieving the purpose of assembling small parts before producing the lighter;

[0021] 5. In the four-piece assembly of the lighter of the utility model example, the sponge is pressed into the sponge seat and can be directly synthesized at one time on the molding mold using a jig after the drainage core is hot-formed, thereby saving the process of screening the T-shaped sponge seat once. This assembly allows the sponge to be pressed onto a synthetic part that is dozens of times larger than before, and the large part will not be placed upside down or sideways in the small cavity of the lighter, thereby solving the inspection problem of a large number of waste products in the production of lighters.

[0028] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Embodiment 1:

[0031] like Figure 1-2As shown, this embodiment provides a four-piece assembly in a lighter, including a flame adjustment plate (sponge) 1, a T-shaped sponge seat 31, a core sleeve 32 and a drainage core 5. The flame adjustment plate 1 has a through hole 2 in the middle, and the upper end of the T-shaped sponge seat 31 can be inserted into the through hole 2 and has an interference fit with the through hole 2; the drainage core 5 is installed in the inner cavity of the core sleeve 32. In this embodiment, the core sleeve 32 is integrally formed at the lower end of the T-shaped sponge seat 31 to form a T-shaped sponge seat and core sleeve composite body 3. The composite body can be formed in one piece with metal or plastic by stamping, upsetting, die casting, injection molding and other methods during the production process. Compared with the original method of producing the two components separately, the structure of the composite body is easier to produce, and also reduces the later installation process, thereby improving the yield rate of the lighter.

[0032] The drainage core 5 and the core sleeve 32 of this embodiment are also integrated. Specifically, during the production process, after the T-shaped sponge seat and the core sleeve composite body 3 are pre-embedded into one end of the drainage core 5 mold, plastic powder is injected into the inner cavity of the composite body and the mold cavity connected with the drainage core 5 mold, and then thermoplastic molding is performed, so that the T-shaped sponge seat and the core sleeve composite body 3 are connected to the drainage core 5 as a whole, and the original form of producing the upper end of the drainage core as a T-shaped big head and assembling it with the T-shaped inner cavity in the core sleeve so that the drainage core will not fall after entering the core sleeve is changed to an embedded integrated molding so that it will not fall off, thereby greatly saving production costs according to customer requirements, and this structure can ensure that it will not fall off even without the assistance of the extension tube 33.

[0033] The side wall of the core sleeve 32 is provided with a guide groove 4 connected to the inner cavity, which is used to connect the liquid or gas with the inner cavity of the lighter during inflation and deflation.

[0034] The four-piece assembly in the lighter of the present embodiment combines all the parts into one piece and then assembles them into the lighter in the factory, which can greatly improve production efficiency and is conducive to automated production. In addition, the production method of the assembly reduces the number of parts, optimizes the structure, reduces the scrap rate, and solves the problem of the sponge and the T-shaped sponge seat being placed upside down, too little, or tilted during the installation process, and also reduces the labor intensity of workers who need to stretch their necks and lean forward to let their eyes vertically enter the narrow space in the lighter for inspection. At the same time, it also optimizes the problems of flame change, sparking, and difficulty in adjustment after the manufacturer intentionally reduces the sponge area to reduce the reversed position.

[0035] Embodiment 2:

[0036] like Figure 3 As shown, on the basis of the first embodiment, this embodiment adds a structure of an extended trust pin 33 , and the extended trust pin 33 is located at the lower end of the core sleeve 32 and is integrally formed with the core sleeve 32 .

[0037] The guide groove 4 of this embodiment is not connected to the inner cavity of the core sleeve 32.

[0038] Embodiment three:

[0039] like Figure 4 As shown, the drainage core 5 can be formed in one piece or produced separately according to customer requirements. The drainage core 5 of this embodiment is a cylindrical shape produced separately.

[0040] Specifically, in order to make the drainage core 5 more resistant to bending, the upper end diameter of the drainage core 5 is slightly larger than the lower end diameter, so that the drainage core 5 can be more firmly fixed in the core sleeve 32.

[0041] In addition, an extension tube 33 is integrally formed at the lower end of the core sleeve 32, and the thin wall of the extension tube 33 can be riveted inward to prevent the drainage core 5 from falling off. The lengths of the drainage core 5 and the extension tube 33 can be customized according to customer needs. In addition, the guide groove 4 is not connected to the inner cavity of the core sleeve 32.

[0042] Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in this application.
