Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a catalytic nozzle for a lighter, which is mainly used for the nozzle of a cigarette lighter.

Conventional technology In recent years, there has been an active movement in the cigarette lighter industry to improve profitability through superiority in the market and higher added value. This is happening rapidly. Among them, many so-called internal combustion type lighters are being commercialized as windproof lighters, which use a fine nozzle hole diameter to increase the speed of gas ejection, suck in primary air, and use it as a burner to perform part of the combustion inside the crater. . Furthermore, there is an active movement to further improve the performance against wind by installing a catalyst in the vent of the Windbu P-Flyter.

Conventionally, this type of cigarette lighter has a structure in which a coiled catalyst wire is fixed to a tinder ring by passing one or two holding guide wires through the coil.

Problems to be Solved by the Invention In such a conventional configuration, the impact caused by the falling ring of the lighter body can cause the coil shape to become distorted or deformed, and in extreme cases, the catalyst wire may even break, resulting in the loss of gas flow. The catalyst wire came off the flow path, causing variations in the catalytic reaction.

Means for Solving the Problem In order to solve this problem, the present invention has a catalyst wire made of platinum material or the like, a hollow elongated hole, and a guide groove for winding the catalyst wire around the outer periphery. a lower crater ring having a coil guide plate, an engaging portion for positioning and fixing the coil guide plate, and a lower crater ring for sandwiching and fixing the coil guide plate and the catalyst wire, which are positioned and fixed to the lower crater ring. The upper crater ring is press-fitted into the upper crater ring.

With this structure, the catalyst wire is always held and fixed in a fixed position with respect to the nozzle ring, and the coil guide plate ensures that it is held in the upper and lower positions by the coil guide plate even in the event of a fall impact of the lighter body or the like. Also, the shape of the coil itself (winding pitch)
In addition, the coil end of the catalyst wire is compressed and fixed by the catalyst wire guide groove provided on the coil guide plate and the upper nozzle ring, so it does not shift, resulting in the positional relationship of the catalyst wire with respect to the nozzle ring. becomes certain.

Embodiment FIGS. 1, 2, 3 and 4 show a catalytic nozzle for a lighter according to an embodiment of the present invention. The configuration will be explained according to the numbers along with the drawings. In FIGS. 1, 2, 3, and 4, reference numeral 1 denotes a lower crater ring, which has engaging portions 1& of a coil guide plate, which will be described later, at two opposing locations on the upper surface side.

2 is an upper nozzle ring which clamps and fixes the coil guide plate and the catalyst wire between it and the lower nozzle ring 1, as will be described later; 3 is a hollow elongated hole 31L and a guide groove 3b for the catalyst wire 4 made of platinum material or the like. A thin coil guide plate 4a is a coil end portion of the catalyst wire 4.

Then, as shown in FIG.
By placing the coil guide plate 3 on the lower crater ring 1 using 1L and then press-fitting the upper crater ring 2 into the lower crater ring 1, the coil guide plate 3 is inserted between the lower crater ring 1 and the upper crater ring 2. The catalyst wire 4 wound around the coil guide plate 3 is compressed and held between the two fire rolling rings 1.2, and is also clamped and fixed between the two fire rolling rings 1.2. be done. Here, if necessary, both roller rings 1.2 may be press-fitted and fixed using an adhesive.

Next, the combustion process will be explained. The catalyst nozzle according to the present invention is used by being installed above the gas nozzle portion of a lighter. First, increase the flow velocity from either the lower crater ring 1 or the upper crater ring 2,
- Catalytic combustion is started in the catalytic wire 4 at the same time as normal combustion (flame generation) by sucking enough air and diffusing the gas to achieve optimal conditions for combustion. Here, the structure and operation of performing normal combustion by diffusion of gas to achieve optimal conditions for combustion and discharge action of a high voltage generator using a piezoelectric element are not directly related to the present invention. Since it is unrelated and its configuration and operation are already known techniques, the explanation will be omitted. After the combustion has started, the combustion may be temporarily stopped (the flame is extinguished) by wind, etc., but even in this case, if the gas continues to be ejected, the catalytic wire 4 will cause catalytic combustion again. is restarted, and normal combustion is also restarted from this catalytic combustion. However, in the conventional structure, the coiled catalyst wire was not sufficiently held and fixed, so the catalyst wire sometimes came off from the gas flow path and the catalytic reaction did not occur.However, according to the present invention,
The catalyst wire 4 is securely held and fixed on the coil guide plate 3, and the coil guide plate 3 is also clamped and fixed between the lower nozzle ring 1 and the upper nozzle ring 2, so that the catalyst wire 4 is always kept within the gas flow path. 4 will be located.

Effects of the Invention As described above, according to the present invention, a catalyst wire made of platinum material or the like, a coil guide plate having a hollow elongated hole and a guide groove for winding the catalyst wire around the outer periphery, a lower crater ring having an engaging portion for positioning and fixing the coil guide plate; and a lower crater ring that is press-fitted into the lower crater ring so as to sandwich and fix the coil guide plate and the catalyst wire, which are positioned and fixed to the lower crater ring. By having an upper crater ring, the catalyst wire is securely held and fixed to the coil guide plate, and furthermore, the coil guide plate is sandwiched and fixed between the lower crater ring and the upper crater ring. Therefore, the catalyst wire is always positioned within the gas flow path range, and the pre-adjusted positional relationship between the catalyst wire and the gas flow path is unaffected by external loads such as drop impact, allowing catalytic combustion to occur. Normal combustion can be stably obtained and highly reliable. Also, compared to the conventional configuration in which a relatively soft catalyst wire is wound into a single coil and a holding wire is further incorporated into the inner diameter of the coil,
In the present invention, since the catalyst wire is wound around the coil guide plate, it is easy to handle in terms of strength, and there is an extremely large possibility of cost reduction in terms of workability. In addition, since the coil end of the catalyst wire can be compressed and fixed with two crater rings, it is superior in both reliability and cost compared to conventional methods such as spot welding, making it suitable for practical use. The value is extremely large.
