Description

Detailed Description of the Invention

[0001]

This invention relates to a cigarette fire extinguisher. This fire extinguisher can be suitably used in an environment where it is necessary to extinguish a cigarette fire instantly even without an ashtray or water.

[0002]

2. Description of the Related Art Usually, a cigarette is extinguished by extinguishing it in the ashtray or on the ground, or by dropping it on the ground and trampling it in a place without the ashtray.

[0003]

However, in the case of smearing, it takes a long time to completely extinguish the fire, and most smokers leave the tip of the burning cigarette just by rubbing it a few times. Therefore, smoke will continue to be emitted for a long time in the absence of a smoker, which not only causes annoyance to smokers in the vicinity but also causes a fire by reburning in a place without an ashtray.
However, it is unrealistic to require smokers to carry ashtrays, and there are very few suitable ashtrays.

An object of the present invention is to solve the above problems and provide a portable fire extinguisher suitable for carrying, which can extinguish a cigarette instantly without an ashtray or water.

[0005]

In order to achieve the object, a cigarette fire extinguisher according to the present invention is made of a non-combustible material and has a cylindrical shape in which an inner edge of a cross section orthogonal to an axis has a circular penetrating shape, and its inner diameter is m, where t is the outer diameter of the cigarette, m
Is greater than t at at least one axial end,
It is characterized in that it is smaller than t at at least one intermediate point.

[0006]

When the cigarette fire extinguisher of the present invention is used to extinguish a smoking cigarette, the tip of the burning cigarette is inserted into the cigarette fire extinguisher from the end of m> t. m
Since> t, ash can be easily inserted without spilling outside. Then, it is pushed to the midpoint of m <t. Since m <t at the midpoint, the tip of the burning cigarette is compressed in the radial direction. Therefore, tobacco leaves are closely packed, and the air passages in the tobacco are blocked to completely extinguish the fire. After extinguishing the cigarette, you can throw it out in the trash, and it is completely extinguished, so there is no danger of reburning. Further, since this cigarette fire extinguisher is made of a non-combustible material and has a penetrating cylindrical shape, it can be easily cleaned by blowing on it after use to be ready for reuse.

In the case of a cigarette fire extinguisher in which m gradually decreases from the one end toward the intermediate point, the tip of the cigarette slides along the inner peripheral surface from the position where m = t. It becomes easy to push to the middle point of. As a result, m at the midpoint can be made sufficiently small, and the compression rate at the midpoint becomes high. In other words, the porosity of the tobacco tip when reaching the midpoint becomes extremely low, and the fire can be extinguished instantly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a cigarette fire extinguisher of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a cigarette fire extinguisher of an embodiment, and FIG. 2 is an axial sectional view showing a use state of the cigarette fire extinguisher.

The cigarette fire extinguisher 1 is made of a non-combustible material such as brass and has a vertically symmetrical cylindrical shape in which the inner edge of the cross section orthogonal to the axis is circular and penetrates. The wall thickness is approximately uniform at about 1 mm, and the inner and outer diameters change continuously in the axial direction so that the inner and outer diameters are large at both ends and small at the middle portion. Of particular importance is the inner diameter, where m is the inner diameter, and t is the outer diameter of the cigarette T (usually 8 mm), m is greater than t at both ends 2, 2 in the axial direction, for example, about 10 mm, It gradually decreases from both ends 2 and 2 toward the intermediate point 3,
A minimum of 6 mm at the intermediate point 3 after passing through the position 4 that is equal to t on the way.
Designed to be degree.

When the cigarette fire extinguisher 1 is used to extinguish a smoking cigarette T, the tip of the burning cigarette T is cut from one end 2 of the cigarette T as shown in FIG. Insert in fire extinguisher. Since it is vertically symmetrical, either end 2 may be used. Since m> t, ash can be easily inserted without spilling outside. Then, as shown by the chain double-dashed line in FIG. From the position 4 at which m is equal to t on the way to the intermediate point 3, m <t. Compressed in the direction. Therefore, the leaves of the tobacco T are closely packed, the air passage in the tobacco T is blocked, and the fire is completely extinguished within 3 seconds. Moreover, since the cigarette T itself blocks the smoke outlet, the smoke does not rise. After extinguishing the cigarette T, it can be discarded in the trash box, and since it has been extinguished completely, there is no risk of reburning even if it is discarded. Further, since this cigarette fire extinguisher 1 is made of a non-combustible material and has a cylindrical shape that penetrates, it can be easily cleaned by blowing on it after use and ready for reuse.
Furthermore, since this cigarette extinguisher 1 has a small tubular shape,
You can also carry it in a container with a lid. Therefore,
Even field workers in forests can smoke without worrying about forest fires.

In this example, the cigarette fire extinguisher 1 has a vertically symmetrical shape. However, only the upper half has the requirements of the present invention, and the lower half has a more stable shape with a wider end and a lower edge. You may fix it on an ashtray at any time by fixing a magnet.

[0012]

[Effects of the Invention] Since there is no dullness after smoking,
Don't bother smokers. Fire can be prevented if used by workers in forests and construction sites.
