Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a smoking device, and more specifically to a smoking aid that suppresses purple smoke generated during smoking.

[Conventional technology]

Cigarette smoke is divided into so-called mainstream smoke, which is directly inhaled by smokers, and so-called sidestream smoke (purple smoke), which rises from a placed cigarette.Sidestream smoke is more irritating and unpleasant than mainstream smoke, and is harmful to the human body. It is known.

Compared to mainstream smoke, sidestream smoke has a generation temperature of 200~200°C.
It is characterized by its low temperature of 300℃ and strong alkalinity due to the amines produced.

One way to easily suppress such sidestream smoke is to wrap a cigarette in paper containing finely divided carbon and use the combustion heat of the carbon to suppress the generation of sidestream smoke. Not only did the thicker packaging result in a larger packaging volume, but the ignited carbon particles could fall, creating a risk of fire.

Additionally, a method has been devised in which a non-flammable tube is placed over the burning part of the cigarette, but this method has the disadvantage that the longer the tube is, the more the cigarette will disappear.

There are ashtrays that extinguish the fire naturally by inserting a cigarette into a vertical hole, and in this case too, the generation of sidestream smoke can be suppressed for a short period of time, but these ashtrays are made of non-breathable material. Since the fire is extinguished by suppressing the air supply, it has the disadvantage that in order to continue smoking, care must be taken to ensure that the fire does not go out.

[Problem that the invention attempts to solve]

The present invention eliminates the various drawbacks of the conventional means as described above, and provides a smoking aid that safely and easily suppresses unpleasant components in sidestream smoke, and that can easily extinguish cigarettes when necessary. The purpose is to provide

[Means for solving problems]

In order to solve the above-mentioned problems, the smoking aid of the present invention has a first layer 5 that is heat-resistant, breathable, and has low thermal conductivity, and a second layer 6 that is impermeable and has high thermal conductivity. A cigarette holding member 2 is formed by laminating layers such that one of the layers is on top, and a cigarette holding member 2 is provided with a cigarette inserting member that penetrates through the boundary surface 7 of the first layer 5 and the second layer 6 and opens on at least one side. It has a structure in which holes 3 are provided.

The first layer 5 has a heat resistance of 800 to 1200 degrees Celsius to the extent that it will not be burned or deformed by cigarette fire, has breathability that can supply the air necessary for the cigarette to continue burning, and has sufficient heat resistance to burn the cigarette. It is made of a material with a low thermal conductivity that can sufficiently store heat without dissipating it, and such a material has a thermal conductivity of 0.5 min ^-1 cm ^-2 or more at a pressure difference of 40 mm water column. Selected from laminates of asbestos, alumina fiber, quartz glass fiber, etc. below 0.1Kcal・m ^-1・hr ^-1・deg ^-1 .

The second layer 6 is made of a material that is sufficiently impermeable to block the air supplied to the burning tobacco and has a high thermal conductivity to dissipate the heat of combustion of the tobacco and reduce the temperature of the burning part. Such materials are selected from metals, high temperature plastics, ceramics, etc.

The hole 3 is large enough to allow insertion of a cigarette, and preferably there is no gap between the cigarette and the inner wall of the hole 3 in order to prevent air from flowing along the surface of the cigarette.

[Effect]

When it is necessary to place a cigarette in the smoking aid of the present invention, a lit cigarette is inserted into the hole 3 of the cigarette holding member 2, and the burning part is placed inside the first layer 5 having air permeability. When this is done, air is supplied through the layer 5, so that the cigarette continues to burn without being extinguished.

Moreover, since the first layer 5 has a low thermal conductivity, the combustion heat is accumulated without being dissipated and increases the temperature of the combustion part, which causes sidestream smoke (purple smoke) with an unpleasant irritating odor that is generated during low-temperature combustion. ) occurrence is suppressed.

Furthermore, the smoke that diffuses into the layer 5 from the combustion part passes through the layer 5 that has become hot due to the accumulated combustion heat, so that the smoke that escapes to the outside of the cigarette holding member 2 as a result of being thermally decomposed is Further decrease.

In this way, the cigarette that continues to burn inside the first layer 5 has holes 3 that penetrate through the interface 7 between the first layer 5 and the second layer 6 and are provided as continuous holes. , the combustion part can be easily positioned inside the second layer 6 without extracting it from the hole 3, but at this time, since the second layer 6 is non-breathable, the supply of air is cut off, Moreover, its high thermal conductivity dissipates combustion heat and lowers the temperature, so the cigarette stops burning and is extinguished.

Further, when a cigarette is inserted through the opening provided in the second layer 6 and the burning part at the tip is inside the first layer 5, the burning part will naturally move into the second layer as combustion progresses. 6, the cigarette will be extinguished automatically.

[Embodiment 1] FIG. 1 is a sectional view of a smoking aid that is an embodiment of the present invention.

In this figure, an ashtray 1 includes a cigarette holding member 2 which is made by laminating a first layer 5 that is heat resistant, air permeable, and has a low thermal conductivity, and a second layer 6 that is non-air permeable and has a high thermal conductivity. The cigarette holding member 2 is provided with a hole 3 for inserting a cigarette through the interface 7 between the first layer 5 and the second layer 6. It is open on both sides.

The first layer 5 is a layer made of 70% Al ₂ O ₃ and 30% SiO ₂ with a heat resistance of 1200°C, and its thermal conductivity
0.04Kcal・m ⁻¹・hr ⁻¹・deg ⁻¹ and air permeability is 2.4・min ⁻¹・cm ⁻² at a pressure difference of 40 mm water column.

The second layer 6 is made of non-porous ceramic and has a thermal conductivity of 0.6 Kcal·m ^-1 ·hr ^-1 ·deg ^-1 .

When a lit cigarette 4 is inserted into this smoking aid and the burning part 9 at the tip is positioned inside the first layer 5, the cigarette continues to burn without extinguishing, and at this time, no purple smoke is generated. The unpleasant and unpleasant irritating odor has been drastically reduced.

The cigarette 4 is then inserted shallowly to transfer the burning portion to the second layer 6, whereupon it easily extinguishes.

Furthermore, if the cigarette 4 that had continued to burn inside the first layer 5 was left unattended, as it burned, the burnt portion 9 would eventually move to the second layer 6 and soon disappear by itself.

[Embodiment 2] FIG. 2 is a cross-sectional view of another embodiment of the present invention.

In the smoking aid shown in the figure, a cigarette holding member 2 consisting of a first layer 5 and a second layer 6 similar to those shown in Example-1 is placed on an ashtray 1 with the second layer 6 facing downward. One of the holes 3 for inserting a cigarette provided in the holding member 2 is closed only on the lower surface side. In this way, the hole 3 for inserting a cigarette in the present invention
may be open on at least one side and closed on the other side.

In this embodiment as well, a lit cigarette is inserted into the hole 3.
The same results as in Example-1 were obtained.

[Embodiment 3] FIG. 3 is a cross-sectional view of another embodiment of the present invention.

In the smoking aid shown in the figure, there is a container 1 that also serves as an ashtray.
The second layer 6 is formed by providing a layer of granular members made of a non-breathable material with high thermal conductivity inside the second layer 6, and on top of the second layer 6, a heat-resistant material with breathable heat conductivity and low thermal conductivity is provided. A tobacco holding member 2 is formed by providing a layer of the produced granular material and using this as a first layer 5.

The hole 3 into which the cigarette is inserted is formed at the same time as the cigarette is pushed into the holding member 2.

The first layer is made by molding a heat-resistant, breathable, and low thermal conductivity material such as Denka Alsen Board (manufactured by Denki Kagaku Kogyo) into granules of approximately 3 mm in size, and the second layer The first and second layers 6 are formed by rocking by using a granular material that is impervious to air and has high thermal conductivity, such as ceramic beads or metal beads, which have a higher specific gravity than the material of the first layer 5. It facilitates restoration.

In this example as well, when a lit cigarette was inserted into the cigarette holding member, the same effects as in Example-1 and Example-2 were obtained.

In this way, the first layer 5 and the second layer 6 in the present invention may be granular layers.

〔effect〕

As mentioned above, with the smoking aid of the present invention, when placing a cigarette, simply inserting a lit cigarette into the cigarette holding member 2 causes the cigarette to continue burning and generates sidestream smoke (purple smoke) that has an unpleasant irritating odor. ), there is no need to worry about it disappearing as with conventional means.

In addition, the present invention is extremely safe as there is no need to drop the flame unlike in conventional methods.Moreover, when you want to extinguish the cigarette, you can extinguish it simply by changing the position of the tip of the cigarette in the cigarette holding member 2, making it easy to handle. is extremely simple.

Thus, the present invention provides a smoking aid that eliminates the various drawbacks of conventional methods, safely and easily suppresses unpleasant components in sidestream smoke, and that can easily extinguish cigarettes when necessary. be.
