Description

Technical Field

[0001] The utility model belongs to the technical field of lighter accessories, and particularly relates to a gasifier for a lighter. Background Art

[0002] The gas outlet mechanism of a lighter generally includes accessories such as an air mixing tube, a gas outlet part, a heat insulation cup, and a conductive structure. The tail of the gas outlet part is inserted into the air mixing tube, and the head of the gas outlet part extends into the heat insulation cup. The gas in the gas storage tank assembly is mixed with air through the air mixing tube, and the mixed gas is sprayed into the heat insulation cup through the gas outlet part. When the conductive structure is electrified, a spark is emitted into the heat insulation cup to ignite the mixed gas in the heat insulation cup to form a flame.

[0003] As described in a lighter burner head disclosed in the patent application No. CN201720976426.X, a conductive cup is sleeved on the upper end of a porcelain cup. The outer section of the conductive cup is installed on the outer wall of the porcelain cup, and the inner section of the conductive cup extends into the inner cavity of the porcelain cup. The distance between the lower end of the inner section and the upper end of the gas outlet part is within the ignition distance range.

[0004] Since the inner section of the conductive cup extends obliquely downward into the porcelain cup, it needs to be bent during processing, which will reduce the structural strength of the connection of the inner section. When the mixed gas sprayed into the heat insulation cup flows upward, it may cause the inner section to bend upward and be damaged. If the inner section of the conductive cup is widened to improve the structural strength, it will hinder the diffusion of more mixed gas, and thus affect the shape of the ignited flame. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a gasifier for a lighter with better structural strength.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: a gasifier for a lighter, including a heat insulation cup and a conductive cup. The conductive cup is sleeved on the outside of the heat insulation cup. A pressure ring is fixedly arranged at the upper end of the conductive cup. The pressure ring presses on the upper end surface of the heat insulation cup. A conductive member is fixedly arranged on the inner ring of the pressure ring. The conductive member and the pressure ring are on the same plane.

[0007] Preferably, the conductive member presses on the upper end surface of the heat insulation cup.

[0008] Preferably, the conductive member is a conductive needle or a conductive sheet.

[0009] Preferably, one end of the conductive member is fixedly connected to the inner ring of the pressure ring, and the other end of the conductive member is on the upper end surface of the heat insulation cup or extends above the inner cavity of the heat insulation cup.

[0010] Preferably, a plurality of the conductive members are provided, and the plurality of conductive members are equally spaced along the circumferential direction.

[0011] Preferably, the conductive member is a conductive ring, and the outer ring of the conductive ring is fixedly connected to the inner ring of the pressing ring.

[0012] Preferably, the inner diameter of the conductive ring is greater than, equal to, or less than the diameter of the upper opening of the heat-insulating cup.

[0013] Preferably, the bottom of the heat-insulating cup is provided with a mounting hole and an air outlet portion, the air outlet portion is inserted and fitted with the mounting hole, and the distance between the conductive member and the upper end of the air outlet portion is within the ignition distance range.

[0014] Preferably, a conductive head is provided on the air outlet portion, and the distance between the conductive head and the conductive member is within the ignition distance range.

[0015] Preferably, the conductive heads are provided on the upper end surface of the air outlet portion and a plurality of them are equally spaced along the circumferential direction.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] 1. By providing a conductive member on the inner ring of the pressing ring and located on the same plane as it, the conductive member can be obtained simultaneously when processing the pressing ring, without the need to bend the conductive member, so as to ensure the structural strength at the connection between the conductive member and the pressing ring. It is difficult for the upward flowing mixed gas to cause the conductive member to bend upward, and the structural strength is good, which helps to extend the service life;

[0018] 2. After eliminating the need to bend the conductive member, the processing technology can be simplified, which can not only improve production efficiency, reduce processing errors, but also help to improve the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1: As shown in Figure 1 and Figure 2 , a gasification furnace for a lighter includes a heat-insulating cup 1 and a conductive cup 2. The conductive cup 2 is sleeved outside the heat-insulating cup 1. A pressing ring 21 is fixedly arranged at the upper end of the conductive cup 2. The pressing ring 21 presses on the upper end surface of the heat-insulating cup 1. A conductive member 3 is fixedly arranged on the inner ring of the pressing ring 21. The conductive member 3 and the pressing ring 21 are on the same plane.

[0034] In this embodiment, the conductive member 3 presses on the upper end surface of the heat-insulating cup 1.

[0035] Conventionally, the heat-insulating cup 1 is made of a ceramic cup, and the conductive cup 2 is made of an iron cup.

[0036] Preferably, the conductive cup 2 and the pressing ring 21 are integrally provided, and the conductive member 3 and the pressing ring 21 are integrally provided, which is convenient for processing and production. Of course, other fixing methods can also be used, such as welding.

[0037] Embodiment 2: As Figure 1 and Figure 2 shown, the rest is the same as that in Embodiment 1, and the difference is that the conductive member 3 is a conductive needle 31. One end of the conductive needle 31 is fixedly connected to the inner ring of the pressing ring 21, and the other end of the conductive needle 31 is located on the upper end surface of the heat-insulating cup 1. Preferably, a plurality of conductive needles 31 are provided, and the plurality of conductive needles 31 are equidistantly distributed along the circumferential direction, which helps to improve the ignition rate.

[0038] In this embodiment, the conductive needle 31 and the pressing ring 21 are integrally provided.

[0039] Embodiment 3: The rest is the same as that in Embodiment 2, and the difference is that the other end of the conductive needle 31 extends above the inner cavity of the heat-insulating cup 1.

[0040] Embodiment 4: As Figures 3 to 6 shown, the rest is the same as that in Embodiment 1, and the difference is that the conductive member 3 is a conductive sheet 32. One end of the conductive sheet 32 is fixedly connected to the inner ring of the pressing ring 21, and the other end of the conductive sheet 32 is located on the upper end surface of the heat-insulating cup 1. Preferably, a plurality of conductive sheets 32 are provided, and the plurality of conductive sheets 32 are equidistantly distributed along the circumferential direction, which helps to improve the ignition rate.

[0041] In this embodiment, the cross-section of the conductive sheet 32 is a sector, a circle, a triangle, a trapezoid, a rectangle, a polygon or other irregular shapes. The conductive sheet 32 is preferably a sector, and the pressing ring 21 and the plurality of conductive sheets 32 cooperate to form an internal gear ring shape.

[0042] In this embodiment, the conductive sheet 32 and the pressing ring 21 are integrally provided.

[0043] Embodiment 5: As Figure 7 and Figure 8 shown, the rest is the same as that in Embodiment 4, and the difference is that the other end of the conductive sheet 32 extends above the inner cavity of the heat-insulating cup 1.

[0044] In Embodiments 2 to 5, when the conductive needles 31 and the conductive sheets 32 are completely located on the upper end surface of the heat-insulating cup 1, they can avoid contact with the upward flowing mixed gas and may be bent, and the reliability is better. At the same time, it can also avoid interfering with the mixed gas, and the fullness of the formed flame during ignition is better. When the conductive needles 31 and the conductive sheets 32 extend above the inner cavity of the heat-insulating cup 1, it helps to shorten the ignition distance to fully ensure the ignition rate.

[0045] Example 6: As Figure 9 and Figure 10 shown, the rest is the same as that in Example 1, and the difference lies in that the conductive member 3 is a conductive ring 33, and the outer ring of the conductive ring 33 is fixedly connected to the inner ring of the pressing ring 21. Compared with the conductive pin 31 and the conductive sheet 32, the conductive ring 33 is not easily bent and has better structural strength.

[0046] In this embodiment, the inner diameter of the conductive ring 33 is greater than, equal to, or less than the diameter of the opening on the heat insulation cup 1.

[0047] When the inner diameter of the conductive ring 33 is greater than or equal to the diameter of the opening on the heat insulation cup 1, the conductive ring 33 is completely located on the upper end surface of the heat insulation cup 1, which can avoid contact with the upward flowing mixed gas and has better reliability.

[0048] When the inner diameter of the conductive ring 33 is less than the diameter of the opening on the heat insulation cup 1, a part of the conductive ring 33 extends above the inner cavity of the heat insulation cup 1, which can play a certain role in gas gathering and make the flame shape more concentrated.

[0049] In this embodiment, the conductive ring 33 and the pressing ring 21 are integrally provided.

[0050] Example 7: As Figure 11 shown, the rest is the same as that in Example 1, and the difference lies in that the bottom of the heat insulation cup 1 is provided with an installation hole 11 and an air outlet part 4, the air outlet part 4 is inserted and matched with the installation hole 11, and the distance between the conductive member 3 and the upper end of the air outlet part 4 is within the ignition distance range.

[0051] In this embodiment, the lower end of the air outlet part 4 is connected with an air mixing pipe 5, the middle part of the air mixing pipe 5 is provided with an air inlet hole 51, the lower part of the air mixing pipe 5 is provided with a pressurizing cavity 52, and a pressurizing sheet 6, a sealing ring 7, a filter screen 8 and a rubber tail cap 9 are sequentially arranged in the pressurizing cavity 52 from top to bottom.

[0052] Example 8: As Figure 11 shown, the rest is the same as that in Example 7, and the difference lies in that the air outlet part 4 is provided with a conductive head 41, and the distance between the conductive head 41 and the conductive member 3 is within the ignition distance range.

[0055] 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.
