CONSTITUTION:If a catalyst wire 6 is so previously wound as to maintain in a hollow state at the initial of winding with respect to guide grooves 5b, 5c of a coil guide plate 5, even if it is deformed due to dropping impact, it is guided via the groove 5c having the same bottom winding width as the coil inner diameter of the wires 6 provided at both ends, and the profile of the groove 5b of the other long side opposed to the bottom of the groove 5b of one long side is set larger than the coil inner diameter of the wire 6. Accordingly, the wire 6 is not removed from the grooves 5b, 5c. Thus, burning gas diffusion in a connector of the plate 5 to the wire 6 is expected to eliminate suppression of a catalyst burning efficiency.

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 chicaret lighter industry to improve profitability through market superiority and high added value, and the development and commercialization of chicaret lighters with new functions has been rapid. is being carried out. 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 install a catalyst in the nozzle of this windproof lighter to further improve its performance against wind.

Conventionally, this type of shikaret lighter has either a coiled catalyst wire as it is or two guide wires that are held inside the coil.
Either the structure was fixed to the crater ring through the book, or the structure used a coil guide plate with a guide groove as shown in FIG. 6, which was proposed earlier by the inventors. That is, the bottom winding was constructed using a coil guide plate 2 having a U-shaped guide groove 2a having the same width and the same inner diameter of the coil constituted by the catalyst wire 1.

Problems to be Solved by the Invention In such a conventional configuration, since the catalyst wire 1 and the U-shaped guide groove 2a of the coil guide plate 2 are in line contact, it is impossible to expect combustion scum to diffuse into this engaging portion. The catalytic combustion efficiency was suppressed, and the heat obtained by the catalytic combustion and accumulated in the catalytic wire 1 was conducted to the coil guide plate 2, thereby further suppressing the catalytic combustion.

Means for Solving the Problems In order to solve the problems, the present invention provides a coiled catalyst wire made of a platinum material or the like, and a bottom portion having a hollow elongated hole for wrapping the catalyst wire around the outer periphery. The winding is made so that the width is the same as the coil inner diameter of the catalyst wire at both ends, narrower than the coil inner diameter of the catalyst wire at the middle part, and the groove outer shape of one long side opposite to the groove bottom of the other long side. The dimensions of the catalyst wire are larger than the coil outer diameter of the catalyst wire, and each groove has a guide groove whose width is wider than the wire diameter of the catalyst wire. A coil guide plate having a fixing protrusion for fixing the terminal, a lower nozzle ring having an engaging portion for positioning and fixing the coil guide plate, and winding the catalyst wire positioned and fixed around the lower nozzle ring. An upper nozzle ring is fixed to the lower nozzle ring so as to clamp and fix the coil guide plate.

With this configuration, if the winding of the catalyst wire is set in advance so that it is initially kept in a hollow state around the guide groove of the coil guide plate, even if deformation occurs due to a drop impact, both ends will remain intact. The winding at the bottom of the catalyst wire, which is the same as the inner diameter of the coil, is guided by a guide groove with a width, and the catalyst wire can be wound at the bottom of either of the opposing guide grooves without deviating from the guide groove. In addition, for deformation in the longitudinal direction of the coil, each guide groove width is wider than the wire diameter of the catalyst wire (because it is provided, the catalyst wire will come into point contact with the guide groove). , combustion scum can be diffused at the engagement part between the catalytic wire and the coil guide plate, and the catalytic combustion efficiency is not suppressed.In addition, the heat obtained by catalytic combustion and accumulated in the catalytic wire is transferred to the coil. The conduction to the guide plate is also extremely reduced, and catalytic combustion is not suppressed.

Embodiment FIGS. 1, 2, 3, 4 and 5 show a catalytic nozzle for a lighter according to an embodiment of the present invention.

The present invention will be described in detail according to the figures and numbers. In FIGS. 1, 2, 3, 4, and 5, 3' is a lower crater ring that has engaging portions 3a for a coil guide plate, which will be described later, at two opposing locations on the upper surface side. ing. 4 is an upper nozzle ring which clamps and fixes a coil guide plate between it and the lower nozzle ring 3 as will be described later; 5 is a guide groove for a coiled catalyst wire 6 made of a hollow elongated hole 5a and a platinum material or the like; 5b and 5C on the outer periphery, and as shown in FIGS. 3 and 4, the intermediate guide groove 5b has a bottom winding whose width dimension B is the same as that of the catalyst wire. The guide groove 5 is smaller than the inner diameter of the coil 6 and is on one of the long sides.
The dimension C between the bottom of the guide groove 5b and the outer diameter of the opposite long side of the guide groove 5b is set larger than the inner diameter of the coil, and the width A of the bottom winding of the guide groove 5C at both ends is the inner diameter of the coil. It is set the same as before. Further, the groove width of these guide grooves 5b and 5c is set wider than the wire diameter of the catalyst wire 6, as shown in FIG. Further, reference numeral 5d designates fixing protrusions provided at opposite ends of the outer periphery of the coil guide plate 5 for fixing the ends of the catalyst wires 6.

When winding the catalyst wire 6 using the guide grooves 5b and 5c, the catalyst wire 6 is wound around the intermediate guide groove 5b so that the catalyst wire 6 is positioned in the hollow of the groove. Coil guide plate 5 whose terminal is fixed around fixing protrusion 5d
As shown in FIG. 2, the coil guide plate 5 is placed on the lower crater ring 3 using the engaging part 3a, and then the upper crater ring 4 is press-fitted into the lower crater ring 3. It is clamped and fixed between the crater ring 3 and the upper crater ring 4. Here, if necessary, use adhesive to attach both fire rings 3 and 4.
may be fixed at the positive size.

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 3 or the upper crater ring 4, and -
Then, catalytic combustion is started by the catalytic wire 6 at the same time as normal combustion (flame generation) due to sufficient air being sucked in and the scum being diffused to achieve the optimum 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, etc. are not directly related to the present invention. Since there is no such system and its configuration and operation are already known, the explanation will be omitted. After the combustion has started, the combustion may be temporarily stopped (the flame is extinguished) due to wind, etc., but even in this case, if the dregs continue to be ejected, the catalytic wire
As a result, catalytic combustion is restarted, and normal combustion is also restarted from this catalytic combustion. However, in the conventional configuration, the catalyst wire 1 and the U-shaped guide groove 2a of the coil guide plate 2 are in line contact as shown in FIG. Combustion efficiency was suppressed, and the heat obtained by catalytic combustion and accumulated in the catalytic wire 1 was conducted to the coil guide plate 2, thereby further suppressing catalytic combustion. On the other hand, according to the present invention, the catalyst wire 6 is connected to the guide grooves 5b and 5 of the coil guide plate 5.
If the winding (j is set in advance so that the winding is maintained in a hollow state at the initial stage), the coil inner diameter of the catalyst wire 6 provided at both ends can be adjusted even if deformation occurs due to a drop impact. The same bottom winding is guided by a guide groove 5c having a width dimension A, and the dimension C between the bottom of the guide groove 5b on one long side and the outer shape of the opposing guide groove 5b on the other long side is the same as the catalyst wire 6.
Since the catalyst wire 6 is set larger than the inner diameter of the coil, the catalyst wire 6 will not be deviated from the guide grooves 5b, 5c, and will be in point contact with the bottom of one of the opposing guide grooves 5b, 5c. becomes.

Furthermore, with respect to deformation in the longitudinal direction of the catalyst wire 6 and the long side direction of the coil guide plate 5, since the groove width of each guide groove 5b, 5c is provided wider than the wire diameter of the catalyst wire 6, The catalyst wire 6 comes into point contact with the guide grooves 5b and 5c. Therefore, combustion scum can be diffused at the engagement portion between the coil guide plate 5 and the catalytic wire 6, and the catalytic combustion efficiency is not suppressed. The conduction to the guide plate 5 is also extremely reduced, and catalytic combustion is no longer suppressed.

Effects of the Invention According to the present invention, the width of the bottom winding for winding the catalyst wire around the outer periphery of the catalyst wire made of a platinum material or the like and having a hollow elongated hole is reduced by the width at both ends. The diameter should be the same as the coil inner diameter of the catalyst wire, and the middle part should be narrower than the coil inner diameter.
The dimensions of the groove bottom on one long side of the bracket and the groove outer diameter on the opposite long side are set to be wider than the coil inner diameter of the catalyst wire, and each groove width is wider than the wire diameter of the catalyst wire. a coil guide plate having a fixing protrusion for fixing the end of the catalyst wire at opposing ends of the outer periphery; and a lower coil guide plate having an engaging part for positioning and fixing the coil guide plate. A structure comprising a crater ring, and an upper crater ring that is fixed to the lower crater ring in a positive manner so as to sandwich and fix the coil guide plate formed by winding the catalyst wire that is positioned and fixed on the lower crater ring. By doing so, it is possible to diffuse the combustion residue at the engagement part between the catalyst wire and the coil guide plate, so that the catalyst combustion efficiency is not suppressed, and the heat obtained from the catalyst combustion and accumulated in the catalyst wire is transferred to the coil guide. The conduction to the plate is also extremely reduced, and catalytic combustion is not suppressed.

Therefore, even if combustion is temporarily stopped, catalytic combustion is restarted by the catalytic wire, and normal combustion is resumed from this catalytic combustion.The re-ignition phenomenon, which is the original purpose of using a catalyst, is the catalytic combustion. Since it becomes possible to perform this extremely efficiently, the re-ignition phenomenon will occur more reliably than in the conventional structure. In addition, by providing a fixing protrusion on the coil guide plate for terminal treatment of the catalyst wire, the catalyst wire is securely held and fixed, and the catalyst shape is stable when the catalyst wire is wound around the coil guide plate. As a result, it is easy to handle until it is assembled into a crater ring, and is extremely valuable from a practical standpoint.
