Description

Smoking smoking equipment

The present invention relates to a smoke-removing smoking device for the purpose of smoke removal and deodorization when smoking cigarettes.

Smoke generated from cigarettes has a unique odor in both sidestream and mainstream smoke, and also adheres to indoor walls and furniture, producing odors and dirt. This is annoying not only for the people around but also for smokers.

Further, as a device conventionally devised to eliminate smoke and deodorize when smoking cigarettes, for example, as shown in

Patent Documents

1 and 2, there is a structure that filters and adsorbs cigarette smoke.

However, these apparatuses are insufficient in filtration and adsorption, and the fluidity of the gas is hindered in the stage of filtration and adsorption.

Also, these devices have disadvantages such as the need for filter replacement and dust collection cleaning.

On the other hand, as shown in

Patent Documents

3 and 4, for example, sidestream smoke rising from tobacco or mainstream smoke (smoke) exhaled by a smoker is introduced into a pipe-shaped tube, and the introduced smoke is introduced to the tip of the tube. An apparatus for decomposing by a heating means installed in the vicinity has been proposed. According to these apparatuses, since the smoke is decomposed by heating, the smoke can be made harmless relatively easily.

However, these apparatuses of

Patent Documents

3 and 4 have a complicated structure and cannot reduce the cost. For example, in the case of the conventional example of Patent Document 3, since the first cover that introduces smoke exhaled by the smoker is installed outside the exhaust inner cylinder that houses the cigarette, the outer diameter is increased and the structure is also increased. It is complicated and heavy, and cost cannot be reduced. Moreover, since a cigarette holder is attached to the cigarette cigarette mouth and smoke is sucked from the cigarette mouth of the cigarette holder, the cigarette holder is easily soiled with dirt and the like, and it takes time and effort to clean the cigarette holder.
On the other hand, in the case of the conventional example of Patent Document 4, it is necessary to provide a separate mainstream smoke blowing port in addition to the portion that sucks tobacco, the flow of detoxifying the sidestream smoke of cigarettes with candles, and the smoke exhaled by the smoker Since the flow of processing the wastewater with the purification material is provided separately, not only the structure becomes complicated, but also the apparatus becomes larger, the weight becomes heavier, and the cost cannot be reduced.

In the case of Patent Document 3, since the first cover and the second cover are connected at a right angle, when the second cover is oriented in the vertical direction, the first cover faces in the horizontal direction. For this reason, even if the convection effect due to the temperature rise of the electric heater occurs, the sidestream smoke generated from the cigarette tip tends to flow backward to the opening side (upstream side) of the first cover. In addition, the cigarette is installed in a horizontally installed exhaust cylinder, and one end of the cigarette is blocked by a mouthpiece. There is a risk that a fire that is lit tends to be incompletely burned and a suitable combustion cannot be obtained.

JP 2007-259842 A JP-A-8-154650 No. 7-41358 JP-A-5-207871

The present invention has been made in view of the above points, and its purpose is to allow tobacco smoke to flow smoothly, effectively decompose and detoxify the smoke, and at the same time have a simple structure, and further reduce the size of the device. An object of the present invention is to provide a smoke-removing smoking tool capable of reducing the manufacturing cost.

A smoke smoking device according to the present invention includes a smoking tube, and a cigarette combustion portion for storing a cigarette that burns is provided on the upstream side of the smoking tube, and a combustion heater is provided on the downstream side of the smoking tube. A smoke exhaust combustion exhaust section is provided to store both sidestream smoke generated from the burning cigarette and mainstream smoke discharged from the mouth of the smoker who smoked the cigarette, through the smoking pipe to the combustion heater. A smoke-removing smoking tool that is made to be nearly colorless and odorless by burning, with the downstream portion of the flue gas combustion exhaust portion facing up and down and the upper end as an exhaust port, while the cigarette combustion portion is directed upstream. And is continuously provided at the lower end of the flue gas combustion exhaust portion so as to extend obliquely downward or substantially vertically downward, and further, a cigarette mouth side portion is fixed to an upstream end portion of the cigarette combustion portion. Cigarette holder It is characterized in that a supply air opening formed by providing the air inlet for introducing the mainstream smoke discharged from the mouth of the smoker smoked the cigarette to the circumference. The “up and down direction” is a concept including an oblique up and down direction in addition to a vertical up and down direction.
According to the present invention, the sidestream smoke generated from the tip of the cigarette attached to the cigarette holder and the mainstream smoke (calling smoke) discharged from the cigarette smoker toward the air supply port of the air supply port However, after the inside of the cigarette combustion part rises in a smooth flow toward a diagonally upward or substantially vertical upward direction, and further rises in the flue gas combustion exhaust part facing upwards and downwards, it is decomposed and made harmless by the combustion heater. The air is exhausted from the exhaust port. In other words, the tobacco combustion part is formed so as to be directed obliquely upward or substantially vertically upward toward the downstream side thereof, so that only the ascending airflow due to heating of the combustion heater is applied to the entire smoking tube from the tobacco combustion part to the smoke combustion exhaust part. A smooth air flow is formed, and cigarette smoke flows smoothly on this air flow. That is, there is no fear of backflowing to the air supply port side. This makes it possible to smoke while effectively and reliably eliminating tobacco smoke and smell.
In addition, the smoking pipe has a simple structure in which the flue gas combustion exhaust part, the cigarette combustion part, and the air supply port part are continuously provided, so that the structure of the smoke smoking device can be simplified, thereby reducing the size and cost of the device. Can also be achieved.

Here, it is preferable that the flue gas combustion exhaust part, the cigarette combustion part, and the air supply port part are separate parts and are detachably connected to each other.
In this way, when the exhaust gas combustion exhaust part, the cigarette combustion part, and the air supply port part are configured as detachable separate parts, it is possible to easily attach and detach (replace) the cigarette to the air supply port part having the cigarette holder. In addition, it is possible to easily clean the tobacco ash collected inside the smoking tube and to clean the tobacco combustion part and the air supply port part where the tobacco smoke tends to be attached.

Further, the flue gas combustion exhaust part is configured by turning upward and downward and bending the lower part of the heater storage part storing the combustion heater obliquely downward, while the cigarette combustion part is formed in a substantially straight tube shape and is configured as the exhaust gas combustion exhaust gas. It is preferable to be installed in a state extending obliquely downward by connecting to the lower end of the part.
If the tobacco burning part is formed in a substantially straight tube shape in this way, the flow of air (smoke) passing through the inside can be made smoother. Moreover, the washing can be easily performed.
Moreover, it becomes easy to ignite the tip of the cigarette in a state where the cigarette combustion part is connected to the air supply port part to which the cigarette is attached. Further, after ignition, it is only necessary to connect the tobacco combustion part to the flue gas combustion exhaust part, and the handling thereof can be performed easily.

Further, an opening for discharging cigarette ash is provided at the bottom of the cigarette combustion section on the side to which the air supply port is connected, and the cigarette combustion extends toward the cigarette combustion section at the bottom of the air supply port. It is preferable to provide an ash storage part that covers the opening of the part and stores cigarette ash discharged from the opening.
According to this configuration, the tobacco ash that has fallen into the tobacco combustion section installed in a substantially straight tube shape and inclined obliquely downward toward the upstream side smoothly slides on the inclined surface in the tobacco combustion section and flows upstream. It moves to the side and is easily and reliably dropped from the opening of the tobacco combustion tube into the ash storage portion and stored. When the amount of ash in the ash storage part increases, the ash in the ash storage part can be easily discarded simply by removing the air inlet pipe from the tobacco combustion pipe.

Further, the cigarette holder of the air supply port is formed at a position where the smoker can directly hold the cigarette mouth by exposing the end of the cigarette mouth attached to the cigarette holder to the outside. Is more preferable.
If comprised in this way, a smoker can smoke by directly adding a cigarette mouthpiece. For this reason, it is not necessary to provide a cigarette mouth separately, and the structure is simplified. In addition, the mouthpiece provided separately does not get dirty with the spear, and it is not necessary to clean the mouthpiece.

More preferably, the flue gas combustion exhaust section, the cigarette combustion section, and the air supply port section have substantially the same inner diameter.
If comprised in this way, since the internal diameter of a smoking pipe becomes substantially the same over the full length, a stagnation is lost in the flow of air, and the smooth air flow is formed in the whole smoking pipe.

According to the smoke-removing smoking device of the present invention, tobacco smoke flows smoothly and can be effectively decomposed and rendered harmless. At the same time, the structure is simple, and the device is downsized and the manufacturing cost is reduced. be able to.

It is explanatory drawing of the usage method of the smoke-removing smoker 1-2. It is explanatory drawing of the usage method of the smoke-removing smoker 1-2.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is an overall schematic cross-sectional view of a smoke smoking tool 1-1 according to a first embodiment of the present invention. This smoke smoking tool 1-1 is mainly composed of the following three parts, and constitutes a smoking tube as a whole.

The first part is provided with a cigarette 5 and a cigarette holder 6 into which an air inlet 7 for taking in mainstream smoke discharged from the mouth and air for burning the cigarette 5 and the smoke of the cigarette 5 and a cigarette mouth 8 are inserted. A cigarette mouthpiece 8 is an air supply pipe 11 exposed to the outside.

By placing the cigarette mouth 8 in the air inlet 7 of the air inlet pipe 11, the smoker exhales the mainstream smoke discharged from the mouth from the air inlet 7 without any special action. It can be blown into the tube 11 and exhausted.

The smoke is sent to the flue gas combustion tube 13 by convection, which will be described later, and is completely burned by the combustion heater 1 to become a colorless and odorless gas and is discharged from the exhaust port 4.

The air intake pipe 11 is attached to and used in the tobacco combustion pipe 12, but by replacing the tobacco 5 by making the attachment / detachment easy, the ash of the tobacco 5 accumulated in the tobacco combustion pipe 12 is discarded, and the appliance is washed. Etc. can be done easily.

The second part is a tubular part that covers the cigarette combustion part 10, catches sidestream smoke, and sends the sidestream smoke and the mainstream smoke discharged from the mouth and blown into the air supply port 7 to the flue gas combustion tube 13. This is a certain tobacco combustion tube 12.

The tobacco combustion tube 12 also has a role of temporarily storing the ash of the tobacco 5. This mechanism eliminates the need for frequent ash disposal for smokers and the disposal of ash is a one-time process with a single cigarette. The effect of not contaminating the surrounding area with the ash of tobacco 5 can also be expected. In addition, there is no need to worry about the fire caused by the type of cigarette 5 or scorching the table.

¡By making a part or all of the material of the tobacco combustion tube 12 a transparent material such as heat-resistant glass, the combustion state and remaining amount of the tobacco 5 can be easily visually confirmed from the outside.

The third part is a tubular flue gas combustion tube 13 which is provided with a combustion heater 1 and combusts again the sidestream smoke and the mainstream smoke passing through this tube to form colorless and odorless gas and exhausts it from the exhaust port 4.

The combustion heater 1 may be any kind of combustion heater. That is, the combustion heater 1 may be, for example, an electric heat generation heater or a gas combustion heat generation heater. In short, the temperature necessary for the exhaust smoke of the cigarette 5 to sufficiently burn, and the exhaust gas of the cigarette 5 Any type of heater may be used as long as it has the contact area and shape of the smoke of the cigarette 5 and the heating element necessary for sufficient combustion.

The flue gas combustion pipe 13 flows in the direction of the exhaust port 4 from the air supply port 7 into the smoke-extinguishing smoking tool 1-1 by the upward flow of the heated gas and the chimney effect by making the exhaust port 4 upward in a cylindrical shape. It creates convection and directs mainstream and sidestream smoke to the combustion heater and ventilates inside the smoke smoking device for tobacco burning.

However, in consideration of the possibility that a reverse flow may occur in the gas inside the flue gas combustion tube 13 temporarily and slightly when the smoker sucks the cigarette 5, the volume between the combustion heater 1 and the cigarette combustion part 10 exceeds a certain level. To solve this problem.

As shown in FIG. 4, the main body can be placed on a desk or the like with the exhaust port 4 tilted upward so that the sidestream smoke can be smoothly guided to the combustion heater 1 during tobacco ignition and smoking rest time during combustion. A stand 14 separated from or integrally formed with is used.

Since the smoke smoking device 1-1 of the present invention covers the lit cigarette 5 and the combustion heater 1, the main body may become hot. Therefore, safety aspects such as burns and fires must be fully considered.

Considering the safety aspect that the smoker can safely hold and use the smoke-free smoking tool 1-1 with bare hands by covering the smoke-free smoking tool 1-1 with the heat insulating material 3, and also protect it from fire and burns.

Assuming that the combustion heater is misplaced when the combustion heater is in operation, etc., a safety device that takes into consideration the energy saving and fire safety that the combustion heater 1 automatically stops when there is no physical movement of the smoke smoking device 1-1 for a certain period of time It is preferable to provide.

Assuming that the smoke smoking device 1-1 is overturned when the combustion heater is activated, the combustion heater 1 is turned off when a certain amount of inclination as shown in FIG. It is preferable to provide a safety device that takes into account the energy saving that automatically stops and the safety against fire. Since the main body of the present invention is in the deodorization and deodorization by the recombustion of the flue gas, description of the mechanism system of the combustion heater 1 and its safety device is omitted.

The smoke smoking device 1-1 of the present invention achieves its purpose by a relatively simple method of reburning smoke, and therefore can be realized at a relatively low cost.

Also, it is convenient because there is no need for frequent filter replacement or dust collection, and there are no consumable parts, which is advantageous in terms of actual use and cost. In addition, the ash of the cigarette 5 is temporarily stored in the smoke-removing smoking tool 1-1 so that the ash of the cigarette 5 is not contaminated.

As described above, the smoke smoking tool 1-1 includes a smoking tube, and is provided with a tobacco combustion tube (cigarette combustion portion) 12 that houses the tobacco 5 that burns on the upstream side of the smoking tube, A smoke exhaust combustion pipe (smoke exhaust combustion exhaust) 13 for storing the combustion heater 1 is provided on the downstream side of the inside of the smoking pipe, and a sidestream smoke generated from the burning tobacco 5 and a smoker who has smoked the tobacco 5 A smoke smoking device for guiding both smoke of mainstream smoke discharged from the mouth of the smoke to the combustion heater 1 through the smoking pipe and re-combusting the smoke into a colorless and odorless gas, on the downstream side of the flue gas combustion pipe 13 The portion faces up and down, and its upper end is an exhaust port 4, while the tobacco combustion tube 12 is provided continuously to the lower end of the flue gas combustion tube 13 so as to extend obliquely downward toward the upstream side, Upstream end of the tobacco combustion tube 12 Is provided with an air supply port 7 for introducing mainstream smoke discharged from the mouth of the smoker who smoked the cigarette 5 around the cigarette holder 6 for fixing the portion of the cigarette 5 on the mouthpiece 8 side. A tube (air supply port) 11 is provided.

As a result, sidestream smoke generated from the tip of the cigarette 5 attached to the cigarette holder 6 and mainstream smoke (calling smoke) exhaled from the smoker of the cigarette 5 toward the air inlet 7 of the air inlet pipe 11. Each of them rises with a smooth flow in the cigarette combustion pipe 12 obliquely upward, and further rises with a smooth flow in the flue gas combustion pipe 13 facing upward and downward, and is decomposed and rendered harmless by the combustion heater 1. After that, the air is exhausted from the exhaust port 4. That is, since the tobacco combustion tube 12 is inclined obliquely upward toward the flue gas combustion tube 13, the cigarette combustion tube 12 is exhausted from the tobacco combustion tube 12 to the entire smoking tube only by the rising air flow by heating of the combustion heater 1. A smooth air flow toward the air is formed, and the smoke of the cigarette 5 flows smoothly along the air flow. That is, there is no possibility of backflowing to the air supply port 7 side. This makes it possible to smoke while effectively and reliably eliminating the smoke and smell of the cigarette 5. In addition, the smoking pipe has a simple structure in which the flue gas combustion pipe 13, the cigarette combustion pipe 12 and the air inlet pipe 11 are continuously installed, so that the structure of the smoke smoking device 1-1 can be simplified. It can also be reduced in size and cost.

Further, in the smoke smoking smoking tool 1-1, the smoke combustion tube 13, the tobacco combustion tube 12, and the air inlet tube 11 are separate parts and are detachably connected to each other. The cigarette 5 can be easily attached to and detached from the air supply pipe 11 having 6. In addition, the tobacco combustion pipe 12 and the air inlet pipe 11 can be easily cleaned.

Further, in the smoke smoking device 1-1, the flue gas combustion tube 13 is formed by turning the lower part of the heater housing portion storing the combustion heater 1 obliquely downward while facing the vertical direction, while the tobacco combustion tube 12 is substantially straight. It is formed in a tubular shape and connected to the lower end of the flue gas combustion pipe 13 so as to extend obliquely downward. Thus, since the tobacco combustion pipe 12 is formed in a substantially straight tube shape, the flow of air (smoke) passing through the inside can be made smoother. Moreover, the washing can be easily performed.

Further, in the smoke smoking device 1-1, the cigarette holder 6 of the air inlet tube 11 is connected to the end of the cigarette 5 attached to the cigarette holder 6 on the suction port 8 side (the supply of the air inlet tube 11). It is formed in the position where a smoker can hold the mouthpiece 8 of the cigarette 5 directly by exposing to the smoke side. For this reason, it is not necessary to separately provide the mouthpiece of the cigarette 5, and the structure is simplified. In addition, the mouthpiece provided separately does not get dirty with the spear, and it is not necessary to clean the mouthpiece.

Further, in this smoke smoking smoking tool 1-1, the inside diameters of the flue gas combustion tube 13, the tobacco combustion tube 12, and the air inlet tube 11 are made substantially the same. As a result, the inner diameter of the smoking tube becomes substantially the same over the entire length, so that there is no stagnation in the air flow, and a smooth air flow is formed throughout the smoking tube.

[Second Embodiment]
FIG. 6 is an overall schematic cross-sectional view of a smoke smoking tool 1-2 according to the second embodiment of the present invention. As shown in the figure, the smoke-removing smoking tool 1-2 includes a flue gas combustion tube (a flue gas combustion exhaust portion) 30, a cigarette combustion tube (a cigarette combustion portion) 40, and an air supply port tube (air supply port portion) 50 Are connected to each other, a combustion heater 70 installed in the flue gas combustion tube 30 corresponding to a downstream portion of the smoking tube 20, and the smoke exhausting smoking tube 30 is surrounded and surrounded by the smoke smoking.

As shown in these drawings, the tobacco combustion tube 40 is a cylindrical straight tube, and an opening 41 made of a substantially rectangular cutout is formed on the side (upstream side) to which the air supply tube 50 is connected at the bottom. Is formed. The material of the tobacco combustion tube 40 can be made of various materials such as glass, synthetic resin, and metal. The tobacco combustion tube 40 is preferably configured so that the inside can be seen through from the entire outside or a part of the outside.

8 is a view showing the air supply pipe 50, FIG. 8 (a) is a left side view of the air supply pipe 50, FIG. 8 (b) is a cross-sectional view (a cross-sectional view of the same part as FIG. 6), FIG. 8C is a right side view of the air supply pipe 50. The air supply port pipe 50 is formed from the side (downstream side) of the substantially cylindrical air supply port main body 51 and the cigarette combustion pipe 40 at the bottom of the air supply main body 51 toward the cigarette combustion pipe 40. A substantially rectangular box-shaped ash storage portion 53 extending substantially horizontally is provided. The air supply port main body 51 extends a plurality of (three) arms 55 from the tube portion toward the center, and a cigarette holder 57 is formed at the tip thereof. The cigarette holder 57 is located at the center of the air supply pipe 50. Three air supply ports 58 are formed between the arms 55. In other words, the air supply port 58 is provided around the cigarette holder 57. The cigarette holder 57 has a cylindrical shape, and the inner diameter of the cigarette holder 59 formed of a central opening is the outer diameter of the cigarette (hereinafter referred to as “cigarette”) 100 (more precisely, the outer diameter of the filter portion 103 of the cigarette 100). The dimensions are slightly smaller. The ash storage portion 53 is a rectangular box shape with an open upper surface, and the outer dimensions thereof are substantially the same as the outer dimensions of the opening 41 of the tobacco combustion tube 40. The material of the air supply pipe 50 can be composed of various materials such as synthetic resin and metal.

The flue gas combustion tube 30, the tobacco combustion tube rod 40 and the air inlet tube rod 50 are formed to have substantially the same inner diameter so that they can be connected to each other.

FIG. 9 is a view of the smoke combustion tube 30 of the smoke smoking device 1-2 as viewed from the exhaust port 35 side. As shown in FIGS. 6 and 6, the combustion heater 70 is configured by winding a resistance wire 73 around a heater holding member 71. The heater holding member 71 is made of ceramics, which is a heat-resistant insulating material, and is configured by arranging a plurality of (four) plate portions that are substantially rectangular flat and long in the vertical direction so as to protrude radially from the central axis. The cross section is a cross. Between the plate portions, four ventilation portions 77 penetrating in the vertical direction are formed. In this example, the resistance wire 73 uses a nichrome wire, and the nichrome wire wound in a coil shape is wound around the heater holding member 71 in a spiral shape. Both ends of the resistance wire 73 are drawn to the lower part of the heater holding member 71, connected to the lead wire 79, and drawn to the outside of the smoke smoking device 1-2.

The base 90 is substantially cylindrical as shown in FIGS. 6 and 9 and surrounds and surrounds the heater storage portion 31 of the flue gas combustion tube 30 and further below the heater storage portion 31 of the flue gas combustion tube 30. The bottom surface is configured as a mounting surface 93. The mounting surface 93 is located below the lower end portion of the air supply pipe 50, so that even if the smoke smoking tool 1-2 is placed on a desk or the like, the air supply pipe 50 or the like is placed. Does not touch the desk. The base 90 may be made of a material having a high heat insulating effect. In this example, diatomaceous earth is used, but another material such as a synthetic resin may be used.

Next, how to use the smoke smoking tool 1-2 will be explained. First, the flue gas combustion tube 30, the tobacco combustion tube rod 40 and the air inlet tube rod 50 are separated from each other, and the filter portion 103 which becomes the suction port of the tobacco 100 is placed in the cigarette holder 57 of the air inlet tube 50 as shown in FIG. 10. Insert and hold At this time, the end on the mouthpiece side is protruded by a predetermined dimension on the upstream side (outside) of the cigarette holder 57. Meanwhile, the combustion heater 70 is heated by energizing the combustion heater 70 in the flue gas combustion pipe 30.

Next, as shown in FIG. 11, the outer peripheral portion of the air inlet tube 50 is engaged with and attached to the outer periphery of the upstream end portion of the tobacco combustion tube 40. At this time, the ash storage part 53 of the air inlet pipe 50 is disposed below the opening 41 of the tobacco combustion pipe 40, and the opening 41 is covered by the ash storage part 53.

Next, ignite the tip of the cigarette 100 while smoking the mouthpiece of the cigarette 100. Next, as shown in FIG. 6, the tip inner peripheral portion on the downstream side of the tobacco combustion tube 40 is engaged with and attached to the tip outer periphery on the upstream side of the flue gas combustion tube 30.

At this time, the tobacco combustion pipe 40 surrounding the cigarette 100 is inclined obliquely upward toward the downstream side, and at the same time, the heater storage portion 31 of the flue gas combustion pipe 30 is oriented in the vertical direction (substantially vertical direction). In addition, ascending airflow is generated in the flue gas combustion tube 30 by the combustion heater 70. And the convection which goes to the exhaust port 35 from the air supply port 58 is produced in the inside of the smoking pipe 20 by the rising airflow and the chimney effect of this heated gas. For this reason, the outside air sucked from the air supply port 58 smoothly passes through the smoking pipe 20 and is then exhausted from the exhaust port 35. Accordingly, the sidestream smoke rising from the tip of the cigarette 100 also rides on the airflow and smoothly flows through the smoking tube 20 and is exhausted from the exhaust port 35, and at the same time, the inside of the smoking tube 20 is ventilated. The sidestream smoke is heated and recombusted when passing through the combustion heater 70 (its ventilation portion 77), becomes a colorless and odorless gas, and is exhausted from the exhaust port 35.

On the other hand, after the smoker smokes the mouth of the cigarette 100 exposed to the outside from the air inlet pipe 50 and sucks it, the mainstream smoke (calling smoke) is simply directed to the air inlet pipe 50. Thus, no special operation is required, and the mainstream smoke is smoothly sucked into the smoking tube 20 from the air supply port 58 on the airflow. The mainstream smoke also smoothly flows from the cigarette combustion tube 40 to the exhaust smoke combustion tube 30 together with the sidestream smoke, and after being recombusted by the combustion heater 70, becomes a colorless and odorless gas and is exhausted from the exhaust port 35. .

That is, since the tobacco combustion tube 40 is inclined obliquely upward toward the flue gas combustion tube 30, the smoke tube 20 is exhausted from the tobacco combustion tube 40 to the entire smoking tube 20 only by the updraft caused by the heating of the combustion heater 70. A smooth air flow toward 30 is formed, and the smoke of the cigarette 100 flows smoothly on this air flow, and there is no possibility that the air flows back to the air supply port 58 side. This makes it possible to smoke while effectively and reliably eliminating the smoke and smell of the cigarette 100.

In addition, the smoking pipe 20 has a simple structure in which the flue gas combustion pipe 30, the cigarette combustion pipe 40, and the air inlet pipe 50 are continuously installed, so that the structure of the smoke smoking device 1-2 can be simplified. This makes it possible to reduce the size and cost.

In addition, the smoke smoking device 1-2 has a cigarette holder 57 because the smoke combustion tube 30, the tobacco combustion tube 40, and the air inlet tube 50 are separate parts and are detachably connected to each other. The cigarette 100 can be easily attached to and detached from the mouth tube 50. In addition, the tobacco combustion tube 40 and the air inlet tube 50 that are easily attached to the tobacco 100 can be easily cleaned.

In addition, since the smoke smoking tool 1-2 has the tobacco combustion tube 40 formed in a substantially straight tube shape, the flow of air (smoke) passing through the inside becomes smoother. At the same time, cleaning is easy. Further, by making the tobacco combustion tube 40 a transparent material such as heat-resistant glass, the combustion state and remaining amount of the tobacco 100 inside the smoke smoking smoking device 1-2 can be visually confirmed from the outside.

Also in the smoke smoking device 1-2, since the smoker directly adds the mouthpiece (filter portion 103) of the cigarette 100, the structure is simplified, and the mouthpiece cleaning that occurs when the mouthpiece is provided separately is also possible. Is no longer necessary.

Also, in the case of the smoke-removing smoking device 1-2, since the inner diameters of the flue gas combustion tube 30, the tobacco combustion tube 40, and the air supply port tube 50 are substantially the same, the inner diameter of the smoking tube 20 is substantially the same over the entire length. As a result, the air flow is free of stagnation, a smoother air flow is formed in the entire smoking tube 20, and the smoke and smell of the cigarette 100 can be more effectively extinguished.

By the way, when the cigarette 100 is sucked as described above, the ash at the tip of the cigarette 100 falls into the combustion tube 20, slides on the inclined surface and moves upstream, and enters the ash storage portion 53 from the opening 41 of the tobacco combustion tube 40. It falls and is stored. When the amount of ash in the ash storage unit 53 increases, the air inlet tube 50 is removed from the tobacco combustion tube 40 and the ash in the ash storage unit 53 is discarded.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the smoke smoking device 1-2 described above, when a thermostat 80 is installed as a temperature detecting means in the vicinity of the combustion heater 70 as shown by a one-dot chain line in FIG. 6, and the ambient temperature of the combustion heater 70 exceeds a predetermined value, You may comprise so that it may detect and may interrupt the electricity supply to the combustion heater 70. FIG. Further, although the base 90 is provided in the smoke smoking tool 1-2, the base 90 may be omitted as in the smoke smoking tool 1-1 shown in FIG. Alternatively, the periphery of the flue gas combustion pipe 30 may be covered with another heat insulating member instead of the base 90. Further, the base 90 may be detachably installed on the smoking tube 20.

Further, as indicated by a dotted line in FIG. 6, the upper part of the exhaust port 35 of the flue gas combustion pipe 30 may be covered with a protective net 85 made of a metal net or the like, thereby preventing fingers and the like from being burned by the combustion heater 70. .

In addition, the combustion heater used in the present invention may be either an electric heat generation or a gas combustion heat generation, and the heating method is not limited. It may be.

In the smoke smoking device, the downstream portion of the flue gas combustion pipe is configured to be directed substantially vertically up and down, but may be configured to be directed obliquely up and down instead of vertically up and down. Further, in the smoke smoking device, the tobacco combustion pipe is provided continuously at the lower end of the flue gas combustion pipe so as to extend obliquely downward toward the upstream side, but substantially vertically downward instead of diagonally downward. You may provide continuously in the lower end of a flue gas combustion pipe so that it may extend. Moreover, although the said tobacco combustion tube was formed in the substantially straight tube shape, you may comprise it with a curved tube.
