Description

[Detailed description of the invention] Industrial application field: The present invention relates to an ashtray that can prevent accidents of any size caused by a lit cigarette falling down.

Background of the invention: Smoking is an ancient habit, and there are various types of smoking tools. Ashtrays are one such type, and in addition to disposing of ashes or cigarette butts, those with cigarette trays are also used to temporarily store cigarettes while smoking. Cigarette holders attached to ashtrays are often groove-shaped or gutter-shaped; however, in these ordinary cigarette holders, a lit cigarette that is placed on it gradually burns and shortens, causing the center of gravity to become smaller. It was often lost and fell outside the ashtray, causing fire damage and resulting in serious injuries.

BACKGROUND OF THE INVENTION Various measures have been taken to prevent the harm caused by unpuffed cigarettes falling from the cigarette tray and out of the ashtray. That is, an ashtray 20 or the like in which a groove-shaped cigarette holder is formed to be narrower than the outside diameter of the cigarette to hold cigarettes, or an ashtray 20 in which the mounting bracket 22 of the gutter-shaped cigarette holder 21 is made of bimetal as shown in FIG. This is an example. However, in the former case, if the fire advances to the gripping point, it is inevitable that the cigarette will fall, and in the latter case, when the heat of the flame of the abandoned cigarette is transferred, the bimetal deforms and the gutter-shaped cigarette receiver 21 stands upright, causing the cigarette to slide into the ashtray 20. However, the cigarette did not go out and the smoke continued to swell.

Purpose of the invention: The purpose of this invention is to solve these problems.If a cigarette is left on the attached cigarette tray, the cigarette will first extinguish the burning flame, and then put the cigarette in the ashtray. The purpose is to provide an ashtray into which extinguished cigarettes can slide out. The ultimate objective is to effectively prevent the unpleasant odor caused by continuous smoking of cigarettes and the mismanagement caused by cigarette burns.

Structure/Example of the invention: Hereinafter, one embodiment of the invention will be described based on the drawings.

As shown in FIG. 1 or 2, the ashtray 10 of the present invention includes an ashtray main body 1 and a cigarette tray 4 attached thereto.
It is made up of. The cigarette holder 4 shown in FIG. 1 has a fixing part 2 which is clipped to the edge of the ashtray main body 1, but it can also be directly fixed by casting or adhesive.

The fixed part 2 has a support piece 3 made of a shape memory alloy.
is fixed thereto, and a cigarette holder 4 made of a shape memory alloy is attached thereto. At room temperature, the tobacco receiver 4 formed in this manner has a support piece 3 interposed therebetween, with the tobacco receiver 4 being provided almost horizontally, and the upper part being open in the shape of a gutter, so that cigarettes can be placed thereon. It has become convenient to place it. It is fixed to the ashtray main body 1 by the fixing part 2, and an ashtray 10 is constructed. Shape memory alloys can be used without inserting any mechanical deformation.
A two-way reversible shape memory alloy that exhibits a reversible shape memory phenomenon only through thermal cycles of heating and cooling is used. In addition to the nickel-titanium alloy, this alloy
It is possible to use common alloys for the same purpose.
Further, it goes without saying that the structure of the present invention also includes a case where the supporting piece portion and the cigarette receiving portion are integrated into one body due to manufacturing procedures.

Functions and effects of the invention: When the ashtray 10 of the invention is actually used, if a smoking cigarette is placed on the cigarette tray 4 in the gutter state shown in FIG. 1 or 3 and left there, the cigarette will gradually burn out. The crater approaches the cigarette tray 4,
reach.

The heat of the cigarette flame is transmitted to the tobacco receiver 4 and further to the support piece 3 via the tobacco receiver 4, raising the temperature of these. When the temperature rises, the support piece 3 and the tobacco holder 4 made of shape memory alloy gradually transform into a preset shape corresponding to the temperature rise. That is, as shown in FIG. 4, the cigarette holder 4 curls from a gutter-like shape, and the edges overlap to form a tubular shape, and at the same time, the support piece 3 behaves in such a way as to make the cigarette holder 4 stand up. In this way, the cigarettes placed in the cigarette tray 4 are wrapped in a tube that is deformed by the heat of the left cigarettes, and are squeezed and extinguished in an oxygen-deficient state.Then, as the cigarettes are extinguished, the temperature drops slightly When the tightening is loosened, the cigarette slides out of the cigarette tray 4 (the state shown in FIG. 2), which was in an upright or nearly upright state, and falls into the ashtray main body 1. Cigarettes dropped into the ashtray 10 are completely extinguished before being thrown into the firetray, making it safe and sanitary.

After the abandoned cigarette is extinguished and safely dropped, each part returns to normal temperature, and the cigarette tray 4 returns to its gutter shape.
The support piece 3 returns to the position of holding the cigarette holder 4 horizontally.

The ashtray of this invention automatically extinguishes a cigarette that is left unsmoked, then drops it into the ashtray's firetray, and then repeats the process of returning to its original state. We will also contribute to the conservation of In addition to this, as long as shape memory alloys are used,
A cigarette tray with a variety of shapes is considered. Both have the function of extinguishing the cigarette by enveloping the part that causes the ignition by utilizing their deformation characteristics, and together with the above effect, they also have the effect of enhancing the taste of moving interiors.
