Description

[Detailed description of the invention] A: Industrial application field This invention relates to a heat-sensitive device that allows a burning cigarette temporarily placed in an ashtray to slide into the center of the ashtray so that it does not fall somewhere other than the ashtray. .

B: Conventional technology Conventionally, a thermostat and a cigarette resting part are provided around the periphery of an ashtray, and when the combustion temperature of the cigarette is transmitted to the thermostat, the cigarette resting part tilts upward, causing the cigarette to slide into the center of the ashtray. Ta.

C: Problems that the invention aims to solve Thermostats are made by bonding together multiple metals with different coefficients of expansion, and as they require advanced technology and are expensive to manufacture, they have not been widely used in general households. .

D: Means for Solving the Problems As mentioned above, the present invention aims to provide a simple heat sensor for ashtrays that does not require advanced technology to manufacture, is inexpensive, and can be widely used in general households.

To explain with reference to the drawings below, a shape memory alloy 4 bent in one direction supported by a saddle 5 on the upper part of the legs 2, 2 of a T-shaped body 1 having legs 2, 2, and a part 6 for holding a cigarette 11 at the tip thereof. It has a structure with

E: Function To explain the function below, the periphery 10 of the ashtray 9
When the main body 1 is clamped and fixed between the legs 2, 2 and the clamping legs 3, 3, and a lit cigarette 11 is placed on the cigarette rest part 6, the shape is fixed to the main body 1 with the saddle 5 as the cigarette burns. As heat is transferred to the memory alloy 4 and the cigarette is returned to the memorized bent shape, the cigarette resting part 6 provided at the tip moves upward, and as the angle of inclination with the fixed part of the saddle 5 increases, the cigarette is rested and burned. The burning cigarette slides into the ashtray. In addition, when placing a cigarette on the cigarette again, the shape memory alloy automatically returns to its original memorized state as heat dissipates, making it possible to place the cigarette on the cigarette again.

F: Example As another embodiment, a shape memory alloy 4 which is bent in one direction and has a cigarette resting part 6 at one end.
It is also possible to have a structure in which the other end is fixed to and integrated with a part of an arbitrary ashtray.

G: Effects of the invention According to the structure and method of use as described above, unlike the thermostat method described in the conventional technology, the manufacturing process is simplified without requiring advanced manufacturing technology, and therefore mass production can be easily carried out. Because the product can be made at a low price, it has become popular in ordinary households and does not cause scorch marks on floor coverings and tatami mats caused by cigarettes in the home.In particular, the causes of fires caused by cigarettes, which occur frequently, are reduced, and valuable property and precious human lives are saved. It has great effects, such as being able to protect people.

Furthermore, the proposed device is removable, making it portable, and can be easily attached to empty cans and bottles, which can be used as substitutes for ashtrays, so it can be used in small spaces such as camping or traveling. if,
It also has the effect of making smoking safer.
