背景技術
一般に、この種のシガーライターは、着火部が

から手間が掛つてコスト高なものになつている。BACKGROUND ART In general, this type of cigarette lighter usually includes a heater in which the ignition part is formed into a spiral shape with a nichrome wire exposed on the surface side.
However, this tends to cause clogging with ash and dregs getting stuck in the gaps between the nichrome wires, which can cause shortening and breakage, or shorten the lifespan of the nichrome wires due to oxidation and deterioration. There is. In addition, the ignition surface is metallic in color and has irregularities due to the spiral nichrome wire, resulting in poor traction properties.
Moreover, since many nichrome wires have to be wound, it is time-consuming and costly.
このニクロム線によるヒーターに代え、電気抵

いう点を解決すべく、粉末治金法で成形焼結した
抵抗発熱体に多数の凹凸着火表面を一体に形成し
たもの（実公昭55−4690号）が知られている。 Instead of this nichrome wire heater, a cigarettelet is made of a resistance heating element using a powder metallurgy method, in which metal oxide powder mixed with electrically resistive powder metal or metal powder is pressure-molded and sintered to provide a smooth ignition surface. In order to solve the problem of ignition failure due to poor air circulation to the lighter (Utility Model Publication No. 47-36294) and its tobacco contact surface, we integrated a large number of uneven ignition surfaces into a resistance heating element molded and sintered using powder metallurgy. The one formed in 1983 (Utility Model Publication No. 55-4690) is known.

点がある。 However, if the surface of a cigarette lighter is made with many irregularities in order to improve ignition performance, although air can circulate well, the structure becomes complicated, manufacturing costs increase, and weak parts are created. This also has the disadvantage that the recesses become clogged with ash and debris.
考案の開示
本考案は、上述した欠点を除去するべく改良し

焼結体で発熱するよう構成されている。 That is, in the cigarette lighter according to the present invention, the ignition surface is curved upward and is formed of a ceramic sintered body, and the ceramic sintered body is housed in a holder having sufficient strength, and the opening edge is made of ceramic. The holder is brought into contact with the outer circumferential surface of the sintered body to serve as one electrode, and the support rod with its upper end buried in the approximate center of the ceramic sintered body is used as the other electrode, and the ceramic is sintered by passing current between these external electrodes. It is designed to generate heat within its body.

ので、強度も大きく、製造も容易である。 In this cigarette lighter, the ignition surface is made of a ceramic sintered body that is curved upward, so even if you touch the cigarette to the ignition surface when lighting a cigarette, it is difficult to make a close contact between the cigarette and the ignition surface, and the air leaks out. Since the circulation is not obstructed, cigarettes can be easily lit. Furthermore, since the curved surface has no irregularities, it has high strength and is easy to manufacture.

ることにより形成できる。 The ignition surface of this cigarette lighter is formed of a fired ceramic material 1 having a low electrical resistance such as silicon carbide or barium titanate and having a specific resistance μ≦10 3 Ωcm. Since the ceramic sintered body 1 is capable of self-heating due to resistance loss, it can itself be constructed as a conductor (see FIG. 1).
Further, the heater 2 may be placed inside the electrically insulating ceramic sintered body 1 made of alumina, silicon nitride, or the like as the conductor (see 2nd section). This heater 2 can be formed by embedding a heating element made of a metal such as Ni--Cr wire or an inorganic non-metal as a component before firing the ceramic material.

よう構成すればよい。 The ceramic sintered body 1, whose upper part is curved, is housed in a holder 3 made of a conductive metal material with sufficient strength. The holder 3 is formed in the shape of a saucer with a generally concave cross section, and protects the ceramic sintered body 1 by connecting its opening edge to the circumferential side of the ceramic sintered body 1 by crimping or brazing. It can also be used as one side of the external electrode. Also, ceramic sintered body 1
A support rod 4 with the upper end of the shaft embedded is provided approximately in the center of the support rod 4, and this support rod 4 is attached so that it can be used as the other side of the external electrode. The support rod 4 and the holder 3 are electrically isolated by interposing insulating rings 5 and 6, and the holder 3 and the support rod 4 can be used as external electrodes to conduct electricity. Further, when the heater 2 is buried, the outer end of the spirally arranged heater 2 may be connected to the holder 3, and the support rod 4 may be connected to the inner end thereof.

ることにより回路閉成するよう構成できる。 In addition, when constructing a cigarette lighter for a vehicle using this ignition part, the ceramic sintered body 1 can be incorporated to generate heat by bringing the holder 3 into contact with the electrical system installed on the socket side of the instrument panel. I can do it. This switch mechanism uses a spring-biased push button made of bimetal, etc., similar to existing ones, and when the push button is press-fitted into the socket of the instrument panel, a ceramic sintered body 1
Alternatively, the heater 2 may be energized, and when the ceramic sintered body 1 rises to a certain temperature, the circuit may be closed by returning to its original state due to spring deflection.

て目詰まり等を全く生じない。 In the cigarette lighter constructed in this way, the ignition surface for lighting a cigarette is formed of a ceramic sintered body 1 that is curved upward. Since the upwardly curved surface of the ceramic sintered body 1 can be made smooth by barrel polishing or the like, no ash or debris will adhere to it, and no clogging will occur.

意の色を付けることもできる。 Moreover, since the shape of the ignition surface is curved upward, when igniting a cigarette, the cigarette and the ignition surface are unlikely to come into close contact with each other, and air circulation is not obstructed, so ignition can be easily performed. Further, the ceramic sintered body can be colored, and any color can be applied to improve the fashionability.

The simple shape ensures air circulation during ignition, making ignition easy without reducing cost and strength, and using an inexpensive ceramic sintered body as a heating element. This makes it possible to reduce costs, and also improves fashionability because color can be deposited on the ignition surface.
