Abstract

PURPOSE:To provide a cigarette lighter adapted to light a cigarette by a solar beam converged through a lens, thereby achieving for a cigarette lighter a semi-permanental usabilty with no use of gas, flint and the like. CONSTITUTION:A through port 4 for insertion of cigarettes is bored in a central portion of a column body 1 such that the port 2 penetrates the body 1 from a reverse side to an upper central surface of the body 1. A leaf spring 3 capable of retaining a cigarette inserted into the port 2 from the reverse side thereof is secured in the port 2. The column body 1 has an external thread 4 formed around an outer periphery of its upper edge. A convex lens 7 is secured to an upper edge of a cylinder 6 having an internal thread 5 engageable with the external thread 4 formed on an interior surface of the lower edge thereof. The convex lens 7 has its focal point be in line with a top end face cigarette inserted into the port 2 by screwing the cylinder 6 into the upper edge of the column body 1. A cigarette lighter utilizing a solar heat is arranged in the above mentioned way. When trying to light a cigarette, a cigarette is inserted into the port 2 up to its upper edge from the reverse side of the column body 1, and retained by the leaf spring 3 thereat, then the convex lens 7 secured to the upper edge of the cylinder 6 is oriented in the direction of the sun.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for focusing sunlight to ignite cigarettes.

Conventionally, various types of lighters have been sold as cigarette lighters, but they all have the disadvantage of being relatively expensive as they require replenishment of gas, flint, batteries, etc.

The present invention is a cigarette igniter that ignites a cigarette by concentrating sunlight with a lens in order to eliminate the above-mentioned drawbacks, and is characterized by the fact that it can be used semi-permanently without the need for gas, flint, etc. That is.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A cigarette insertion hole 2 is opened in the center of the column 1 so as to communicate from the bottom surface to the center of the top surface, and a leaf spring 3 is attached to the insertion hole 2 for securing a cigarette inserted from the bottom surface. A convex lens 7 is attached to the upper end of the cylindrical body 6, which has a male thread 4 carved on the outer periphery of the upper end of the body 1, and an inner thread 5 that engages with the male thread 4 carved on the inner surface of the lower end.
, and the cylinder 6 is screwed onto the upper end of the column 1 so that the focal point of the convex lens 7 coincides with the tip of the cigarette inserted into the insertion hole 2. This is what it is made of.

Next, the effects of the present invention will be explained with reference to embodiment figures.

When lighting a cigarette, the cigarette is inserted from the bottom surface of the column 1 into the insertion hole 2 up to the upper end, and is locked by the leaf spring 3. In this state, the convex lens 7 at the top of the tube 6 is directed toward the sun. Since the sunlight is focused by the convex lens 7 onto the upper end of the insertion hole 2, the upper end of the inserted cigarette is ignited by the focused sunlight. The lit cigarette is pulled out from the insertion hole 2 and smoked, and while the cigarette igniter 8 is carried like a lighter, it can be easily ignited by sunlight during the daytime, and has the remarkable effects mentioned above. 0 that plays
