Description

Technical Field

[0001] The utility model belongs to the technical field of lighter accessories, in particular to a lighter gasification furnace with visible flame. Background Art

[0002] A lighter is an ignition device, which usually includes a shell, a gas storage box assembly, an ignition device, an air mixing tube, a gasifier and a gas supply control mechanism. The gasifier generally includes a gas outlet, a ceramic cup and an iron cup. The gas storage box assembly, the air mixing tube, the gas outlet and the ceramic cup are connected in sequence. The fuel gas in the gas storage box assembly is mixed with the air through the air mixing tube. The mixed gas is sprayed into the ceramic cup through the gas outlet. The ignition device emits sparks towards the ceramic cup, igniting the mixed gas in the ceramic cup to form a flame.

[0003] When using a lighter under strong light, although the ignited flame itself emits light, the brightness of the flame may be suppressed under strong light, especially in the sun. The brightness of the sun far exceeds the brightness of the flame, making it difficult for the ignited flame to be captured by the naked eye, which will cause the user to be unable to confirm whether the lighter has ignited the flame. In order to confirm whether the lighter has ignited the flame, the user generally puts the palm close to the gasification furnace of the lighter to block the strong light, but if the flame has been ignited at this time, since the length of the ignited flame cannot be confirmed, there may be a risk of the flame burning the palm or fingers, posing a safety hazard. Utility Model Content

[0009] Preferably, a flange is provided on the side of the heat-insulating cup, and the lower end of the side plate is bent inward to form a convex edge, and the upper end surface of the convex edge abuts against the lower end surface of the flange.

[0010] Preferably, a nickel-chromium wire is arranged in the transparent tube, and two ends of the nickel-chromium wire extend into between the transparent tube and the top cover respectively.

[0011] Preferably, color-changing beads are fixedly provided on the nickel-chromium wire.

[0012] Preferably, a limiting ring is provided between the top cover and the transparent tube, and the upper end surface of the limiting ring is provided with at least two first slots, one end of the first slot passes through the inner wall of the limiting ring, one end of the nickel-chromium wire is inserted into one of the first slots, and the other end of the nickel-chromium wire is inserted into another of the first slots.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] 1. By providing a transparent tube and an opening on the side of the iron cup, when using a lighter, the user can observe whether there is a ignited flame in the heat-insulating cup through the opening and the transparent tube. In addition, since the transparent tube has a certain light-gathering effect, it helps to improve the brightness and visibility of the flame, making it easier for the user to observe the flame through the transparent tube. The user does not need to block the strong light with his hands, which is more convenient to use. In addition, there is no risk of burns when observing the flame from the side, and the safety is better.

[0017] 2. By setting an opening on the iron cup, it helps to reduce material costs and thus reduce production costs;

[0018] 3. In a weak light environment, such as at night, the lighter used with the gasifier can also be used for lighting. The setting of the opening and the transparent tube can reduce the obstruction of the flame brightness, making it easier for the flame to fully illuminate the surrounding environment, thus expanding the scope of application.
