Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tobacco fire extinguishing element that can extinguish cleanly without wetting the smoke of the smoke without scattering the ash to the surroundings.
[0002]
[Prior art]
Safely extinguishing a cigarette butt that has been provided so far is to extinguish the fire by providing a projection that sandwiches the cigarette on the ashtray, or to extinguish the fire by dropping it into a water pot provided on the ashtray, It is convenient to temporarily extinguish a cigarette that is sucking, but when the side that contacts the protrusion gets wet and smokes again, it does not taste bad, and there is no risk of dropping off, the latter is Because it is in a state where nicotine-dissolved water and cigarette butt are mixed, water must be separated when it is thrown away, which is troublesome.
[0003]
[Problems to be solved by the invention]
In view of the above, the present invention provides a cigarette extinguishing element that can extinguish cleanly by dropping a sucked cigarette by its own weight and can automatically fall after extinguishing.
[0004]
[Means for Solving the Problems]
The tobacco fire extinguishing element of the present invention has a cylindrical body vertically passing through a tobacco insertion path, an upper end joined to an inner surface of the cylindrical body, a lower end is in contact with the inner surface in an extended state at normal temperature, and the insertion is performed during a heat load. Except for a shape memory alloy receiver that bends and deforms by interfering with the road, and a notch window that opens to the peripheral surface of the cylindrical body, the upper end is joined to the peripheral surface, and the lower end is from the notch window at room temperature. It consists of an open body made of a shape memory alloy that bends and deforms by interfering with the insertion path and expands and deforms outside the notch window under a thermal load, and is provided with means for expressing a time difference of thermal deformation in the open body. .
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The open body is selected from a plate-like one to a coil spring-like one, and as a means for expressing the time difference of thermal deformation, the thermal expansion rate is selected from the material, and the degree of thermal deformation due to physical frictional force or elastic force The one that restrains is selected. Therefore, when a cigarette with fire is inserted into the insertion path of the cylinder, it is first received by the open body, and the lower end of the receiver is thermally deformed by a thermal load to hold down the burning part of the cigarette, and at the same time the open body Senses heat and extends out of the notch window and leaves the combustion section. Soon, when the combusting part is extinguished, the receiver is at room temperature and the interference of the insertion path is released, so the cigarette automatically falls due to its own weight, and is opened by the means for expressing the time difference of thermal deformation with a slight delay. The body enters the insertion path through the cutout window so as to be in an interference state, and prepares for the acceptance of the next tobacco burning part.

【Example】
The cigarette fire extinguishing element a according to the present invention will be described in more detail with reference to examples. As shown in FIGS. 1 and 2, as shown in FIG. 1 and FIG. A shape memory alloy receiving body 3 that has a lower end that is in contact with the inner surface in a stretched state at normal temperature and that curves and deforms by interfering with the insertion path 1 at the time of thermal load, and an opening in the peripheral surface of the cylindrical body 2 The upper end is joined to the outer peripheral surface through the cutout window 4 and the lower end interferes with the insertion path 1 from the cutout window 4 at room temperature and is bent and deformed outward from the cutout window 4 at the time of heat load. The cylindrical body 2 is formed as a time difference expressing means so as to be deformed later than the receiving body 3 at the time of transition from the heat deformation state to the room temperature deformation. A bifurcated leg 6 that elastically and detachably holds the outer periphery is joined and hung on the outer periphery of the cylindrical body 2 Formed by hanging a child 7.
[0007]
Explaining the fire extinguishing state of the cigarette extinguishing element a constructed as described above, as shown in FIG. 4, first, a sucking cigarette 8 to be extinguished is inserted into the insertion path 1 of the cylindrical body 2 as shown in FIG. Then, the tip of the combustion part 9 is engaged with the curved deformation part 10 of the open body 5, and soon the lower end of the receiving body 3 receives heat from the combustion part 9 and is thermally deformed, and the curved deformation part 11 becomes the combustion part 9. At the same time, as shown in FIG. 4B, the open body 5 is also thermally deformed and extended and deformed outside the notch window 4. When the combustion section 9 extinguishes in this state, as shown in FIG. 4C, the receiving body 3 extends and deforms so as to follow the inner surface of the cylindrical body 2 and the open body 5 also tries to return to the original shape. Further, the leg 6 tries to engage with the outer periphery of the cylinder 2 with frictional force, so that the return of the open body 5 is delayed with a time difference from the return of the receiver 3, and the extinguished cigarette 8 has a supporting force. Will fall downward from the insertion path 1.
[0008]
The cigarette fire extinguishing element a having such a function is used for an ashtray b as shown in FIG. 5 as an example, and the hanging element 7 is engaged with a hanging hole 13 formed inside the upper lid 12. Thus, the tobacco fire extinguishing element a is suspended from the upper lid 12, and a cap 14 made of a heat-resistant synthetic resin is covered on the upper end of the upper lid 12 so as to cover the upper end of the cylindrical body 2 for use. . Accordingly, the sucking cigarette 8 is inserted into the insertion path 1 from the inner peripheral tapered surface of the cap 14, and the extinguished cigarette 8 is stored in the ashtray body 15, and occasionally the upper lid 12 is removed from the ashtray body 15 to remove the ashtray. The cigarette 8 stored in the main body 15 is discarded.
[0009]
In addition, as shown in FIG. 6, instead of the legs 6 as time difference expression means, one end of the spring 16 is engaged with the mounting seat 17 integrated with the back surface of the curved deformation portion 10 of the open body 5 and the other end is cylindrical. It is also possible to delay the restoration of the open body 5 by the tension of the spring 16 by engaging the receiving seat 18 integral with the outer peripheral surface 2.
[0010]
In addition, as shown in FIG. 7, the tobacco fire extinguishing element A is made of a shape memory alloy having a coil diameter gradually decreasing toward the lower end of the cylinder 2 having a required diameter and a required length at room temperature, and is spring-like. A state in which the open body 19 is suspended, the shape-memory alloy-made receiving body 3 is extended to the lower end of the open body 19 at room temperature, and the curved deformation portion 11 is extended downward from the lower end of the open body 19. In addition, the lower end horizontal portion 20 of the cylindrical body 2 is bent below the lower end of the open body 19 at room temperature, and is bent downward to the protruding end of the horizontal portion 20. What suspended the spring body 22 as a time difference expression means which provided the bending end 21 is also easily recalled from the present invention.
To explain the function of this, if the sucked cigarette 8 is dropped into the insertion path 1 of the cylindrical body 2, the cigarette 8 heats the small diameter portion 23 of the open body 19, and the open body 19 is deformed to have a large diameter. At the same time, the height of the spring body 22 is extended by expansion, and the lower end thereof is engaged with the bent end 21 of the spring body 22. On the other hand, at the time of extension, the curved deformation portion 11 of the receiving body 3 is heated to bend and deform toward the inner diameter side of the open body 19 to support the combustion portion 9 of the cigarette 8 and prevent its fall until extinction. When the cigarette 8 is extinguished, the receiver 3 expands and returns to its original shape, and the open body 19 attempts to reduce its diameter by reducing its extension state, but shortens due to the resistance of the bent end 21 of the spring body 22. A time difference appears in the diameter reduction, and the tobacco 8 extinguished during that time loses its supporting force and falls downward from the insertion path 1. Eventually, the lower end of the open body 19 is released from the bent end 21 and returns to the original form in the initial state.
[0011]
