DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the invention of a buttress receiver using a dry fire extinguishing method, which completely prevents the atmosphere of a room or the like from being polluted by the combustion smoke of the butts under dry conditions.
In addition, odors are sufficiently suppressed to extinguish fire of cigarette butts,
It is an object of the present invention to provide a buttress receiver which can efficiently suppress smoke, has a simple structure, and is easy to manufacture.

[0002]

2. Description of the Related Art If water is used as a method for extinguishing a cigarette butt generated by smoking, simple and accurate extinguishing can be achieved, but in this case, it is necessary to store water in a saucer or the like. It is necessary to frequently replace and clean the fire extinguishing water, and the odor will be unpleasant, which will cause discomfort to the user. In particular, when the fire extinguishing water is scattered, it is absorbed by other objects and it is extremely difficult to clean and deodorize. In addition, since the collected butts have sufficiently absorbed water, it is not easy to incinerate them.

[0003] On the other hand, if the above cigarette butts are left undisturbed, considerable smoke is generated and the atmosphere is polluted.
The present inventor has repeatedly studied to extinguish a cigarette butt as described above under dry conditions, and found that the cigarette butt was extinguished under dry conditions.
Proposals such as 00 (57-197898) were made, and the cigarette butt was successfully extinguished under dry conditions, and its practical use has been achieved.

[0004]

The above-mentioned proposal proposed by the present inventors aims at extinguishing butts under dry conditions, extinguishing butts without allowing smoke to enter in a room. Cleaning, incineration and other handling can be facilitated, but due to the dry extinguishing, the burning of the butts continues for a considerable period of time, so that a considerable amount of smoke is filled in the butt storage facilities, and this filled smoke is Even if it is impossible to confirm the smoke due to the leakage from the seal portion to the outside, there is a high possibility that a considerable odor will leak.

Further, according to the proposal of the present inventor, it is indispensable to store the injected butts in a position other than immediately below the inlet so as to keep the smoke rising from the butts in the cooling container and prevent the smoke from leaking outside. Therefore, it is indispensable to attach a hat-shaped dispersion deploying unit at the position directly below the inlet, and this hat-shaped dispersion deploying unit disperses the injected butts and injects smoke rising from the butts. It is understood that it is a necessary component to keep out of the mouth.
However, a considerable number of man-hours are required for the work of mounting such a dispersed deployment unit body while maintaining a predetermined gap immediately below the input port,
It is difficult to manufacture and assemble. In addition, there is a possibility that the butts or the like thrown into a support rod or the like for holding the dispersing / deploying unit right below the throw-in port may be caught, thereby hindering the function of bending angle. Furthermore, in order to secure the dropping of the butts just below the input port, which is a funnel-shaped funnel, the cap-shaped dispersion part is provided with a certain interval, but such a work is required. In general, the container is large and has a high attitude, so that it has to be an expensive product.

In order to smoothly drop the butts dropped from the funnel into the cooling chamber, it is naturally preferable that the discharge pipe be as large as possible. There is a tendency for some of the smoke to leak out, and there is a limit to the increase in the diameter of the discharge tube. One technique is to smoothly insert the butts in the limited diameter range.

[0007] Further, since it is necessary to take out and process the cigarette butts properly received, it is necessary to disassemble the cigarette butts and set the cigarette butts inside the cigarette butts so that the cigarette butts can be taken out. If a buttress receiver falls down, it is highly possible that such a decomposable body will decompose and scatter the inside of the butts, etc. However, there are still problems such as difficulty in scattering.

[0008]

SUMMARY OF THE INVENTION The present invention has been studied to solve the above-mentioned problems in the prior art and ignited by improving a discharge port of a funnel portion for introducing a charged butt into a cooling chamber. The position where the butts are introduced into the cooling chamber is defined, and the smoke rising from the ignition butts is properly prevented from entering the inlet, and the smoke rising from the ignition butts is also added to the top surface of the cooling chamber. Circulates such that the smoke collected at the top portion is cooled by the external air, descends along the bottom outer surface of the funnel member provided at the top portion, and returns to the bottom of the cooling chamber again. The present invention has succeeded in obtaining a preferable dry-type fire extinguishing butt that effectively prevents the smoke component and odor from leaking to the outside even under the conditions for forming a flow, as follows.

(1) An as-ignited butt is received in a vertical cooling chamber via a funnel to cool and extinguish the fire, and is formed to hang below the funnel. The end of the buttocks having the same diameter is bent to the side of the discharge pipe in the cooling chamber while the end of the pipe remains tubular, and the open end of the discharge pipe is projected so as to be parallel to the axial direction of the cooling chamber. Butt receiver with dry fire extinguishing method.

[0010]

The as-ignited butts are received in a vertical cooling chamber via a funnel to cool and extinguish the fire, and have the same diameter formed by hanging down the lower part of the funnel. When the end of the buttocks discharge tube is bent to the side of the discharge tube in the above-mentioned cooling chamber while keeping the tubular shape, the ignition butts which are successively thrown in at the time of initial injection of the butts are always discharged toward the outer peripheral side at the bottom of the cooling room. As a result, the combustion smoke rises from the outer peripheral side of the bottom of the cooling chamber, and the generated smoke rises along the outer peripheral side of the inner surface of the vertical cooling chamber. Form a state where no smoke is generated.

Further, since the opening end of the discharge pipe is parallel to the axial direction of the cooling chamber, the generated smoke rising along the vertical cooling chamber peripheral side as described above is cooled while the funnel-shaped part is being formed. After reaching the bottom surface (outside), as described above, the rise of the input ignition butts generated smoke causes the action of the air falling from the central part of the cooled cooling chamber toward the lower part of the cooling chamber along the butts discharge pipe, In this way, it is possible to prevent smoke or odor falling along the discharge tube from entering (mixing) into the discharge tube from the opening end parallel to the axial direction of the discharge tube. In other words, it is possible to accurately prevent the above-mentioned descending flow from being led out of the discharge pipe to the outside, and to effectively secure complete smokelessness in a room or the like.

As the amount of butts injected into the cooling chamber gradually increases, the upper surface of the deposited butts gradually rises.
After the emission trajectory a from the vertical opening 34 in FIG. 1 becomes equal to or more than the position where it collides against the inner surface of the cooling chamber 1, the deposited position of the injected butts gradually moves toward the center of the cooling chamber 1. Figure 1
The rising smoke b rises as shown in (1), that is, the rising smoke becomes close to the vertical opening 34. Even if the rising smoke b is generated at the extension of the vertical opening 34, the rising smoke b Only rising smoke parallel to the section 34 substantially avoids entering the discharge opening 34 from the opening 34. It is natural that the level of such butts rises further, so that the rising smoke rising from the central portion of the cooling chamber or the rear side of the curved bottom surface 33 does not enter the opening portion 34 beyond the opening portion 34.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION
To explain the details, the inventors of the present invention have two phenomena of convection and stagnation in the behavior of cigarettes that continue burning in the cooling chamber as shown in the drawing, that is, smoke generated from butts introduced from the funnel body. I knew that. That is, the gas containing smoke or odor generated from the butts has a large ascending power under the condition that the temperature immediately after generation is relatively high, and rises in the cooling chamber, and the cylindrical shape closed at the top by the funnel body. Although a convection phenomenon occurs under the condition of the chamber, when the temperature of the gas thus increased is reduced by the cooling effect of the external air, the gas loses its rising power and eventually sinks below the cooling chamber to form a stagnant state. Therefore, in the cooling chamber, stagnation from the top (naturally, the specific gravity is large) is generally observed at the bottom, even though there is partial convection around the butts during combustion. It can be said that fire extinguishing and smoke extinction without releasing smoke and odor can be achieved by the convection and the stagnation (although this stagnation is supplied to the combustion of the new butts).

Under the above-described conditions, the present inventors assume that a large number of people will meet, etc., and even if a large amount of burning butts such as 5 to 10 tubes are simultaneously injected into the cooling chamber. It has been known that smoke can be effectively extinguished in a smokeless and odorless state. That is, even if a large number of butts are sequentially injected by a large number of smokers into the cooling chamber having a diameter of about 15 cm with the above-mentioned convection and stagnation phenomena in a short time, the cooling chamber stays under the above-described conditions. It is presumed that the fire extinguishing was accelerated due to a significant decrease in the oxygen content of the portion, and in any case, the fire extinguishing function tended to be improved by a large amount of injection.

The inventor of the present invention has obtained a preferable operation based on these practical confirmations by an easy-to-manufacture structure. Specific examples thereof will be described with reference to the accompanying drawings. As shown in FIG. 1, putting the ignited butts 7 immediately after smoking into the cooling chamber 1 through the funnel unit 3 and trying to cool and extinguish the fire itself is the same as the prior art described above by the present inventor. Same, but
In the present invention, the discharge port 34 formed to hang down from the funnel unit 3 is curved to the side of the discharge tube, and the vertical discharge port 34 is formed to protrude to the side of the discharge tube 30. is there. That is, the released ignition butts 7 generally continue burning outside the bottom of the cooling chamber 1.

In FIG. 1, the funnel unit 3
A cushion section 11 having a circular cross section is attached to the outside of the top end of the cooling chamber 1 in order to lock and attach the cooling section 1 to the cooling chamber 1, and the cushion section 11 is formed in a ring shape on the peripheral side of the funnel section 3 with respect to the cushion section 11. The bent engagement portion 31 is resiliently locked, that is, the distal end side 32 of the engagement portion 31.
Is pressed down while being in contact with the outer side from the top of the cushion portion 11, whereby the engagement portion 31 is appropriately bent and expanded, and the cushion portion body 11 is also appropriately elongated to elastically engage, which is preferable. It is configured to be attached to the cylindrical cooling chamber 1 under airtight sealing conditions. Moreover, the funnel part 3 is placed in the cooling chamber 1
, And the direction of the discharge port 34 in the cooling chamber 1 can be appropriately changed.

FIG. 1 shows a simple structure according to the present invention. That is, the structure according to the present invention is set on a concrete surface or soil layer, and is directly provided on the bottom surface of the cooling chamber 1. However, when the device according to the present invention is set on a Japanese-style room or a dew surface, it is preferable to provide a leg for taking a space between the cooling room 1 and the bottom surface. Further, a reinforcing member 14 can be appropriately provided in an opening or an intermediate portion of the cooling chamber 1.

FIG. 2 shows a case where the above-described cooling chamber 1 is set in the external container 2. In this case, the cushion 11 is attached to the external container 2 in the same manner as in FIG. Is provided, and the funnel unit 3 is attached. The discharge tube 30 of the funnel unit 3 is short and small, and the external container 2 is separately provided.
Funnel unit 3 for cooling chamber 1 as an internal container set by mounting seat 12 of hanging hardware 13 on support seat 20 of
The discharge pipe 30a has a curved bottom surface 33 and a vertical opening 34 formed in the same manner as in FIG. 1 in such a discharge pipe 30a.

When the external container 2 is also used as shown in FIG. 2, the joint between the cooling chamber 1 and the funnel 3a is bent so that the cushion 15 is bent.
Is locked by locking the bent portion 33, but the seal is of a double structure, and the input port 30 is connected to the input port 30a.
, And may have a light engagement relationship because the funnel 3a is unlikely to be disengaged even if it falls down.

The functional relationship of the present invention as described above is typically as shown in FIG. 1 and FIG. 2, and the butt 7 put into the cooling chamber 1 from the discharge pipe 30 or 30a.
Is a curved bottom surface 3 formed by projecting the lower end of the discharge pipe 30 toward the side wall of the cooling chamber 1 as shown by an arrow a in FIG.
The air is discharged to the side by the orientation of 3, and is inverted on the inner surface of the cooling chamber 1 and falls and accumulates around the inner surface of the cooling chamber. The smoke generated by the combustion of the butts 7 is light under high temperature conditions, rises along the inner surface of the cooling chamber as shown by the arrow b, and gathers at the outer peripheral part of the cooling chamber on the lower surface of the funnel 3 to form an outer part. Due to the cooling by air, its specific gravity increases. The smoke whose specific gravity becomes large in this manner causes a convection phenomenon in which it falls along the lower surface of the funnel 3 and sequentially falls in the cooling chamber 1 toward the center as shown by an arrow b '. Then, it descends along the lower surface of the discharge tube 30, and such a descending flow appropriately avoids entering the vertical opening 34 and avoids entering the curved bottom surface 33, and appropriately avoids the cooling chamber 1. Sinks into the lower center of the cooling chamber 1
A stagnant layer is formed in the lower part of the cooling chamber, and the stagnated layer is held in the cooling chamber 1, and is further cooled down in the holding state of the cooling chamber to further reduce the volume and reduce the volume to be held at the bottom of the cooling chamber 1. Will remain. The cooling chamber 1 as described above
The generation or flow of smoke in the inside and the reduction and concentration of smoke components at the bottom are sufficiently confirmed by experiments using a cooling chamber 1 such as made of glass, or by fouling of accumulated butts at the bottom of the cooling chamber 1.

According to the present invention as described above, the butt of the ignited cigarette is received in the cooling chamber via the funnel unit 3 and cooled to extinguish the fire. The discharge pipe 33 is bent in the cooling chamber so as to protrude to the side of the discharge pipe 30, and the discharge port 3 having a vertical shape or a bottom protruding and opening at an angle to the pipe axis direction.
In the initial stage of the injection of the butts 7 into the cooling chamber 1, the injected butts are discharged and deposited in the direction of the wall surface of the cooling chamber, thereby limiting the possibility that smoke generated from the butts enters the discharge port 34. Since the discharge port 34 is vertically perpendicular to the cooling chamber 1 or has an inclined bottom protruding downward, it is possible to prevent the rising smoke from entering the discharge port. The protrusion amount of the discharge port 34 to the side in the discharge pipe 30 is effective when it is 5 mm or more. Generally, it is preferable that the discharge port 34 is about 5 to 20 mm to obtain a preferable effect of preventing ascending smoke from entering.

As shown in FIG. 2, the outer container 2 comprises an outer container 2 and an inner container 1 set in the outer container 2. The inner container 1 serves as a cooling chamber. By receiving the butts in the funnel part 3a set in the cooling chamber 1 through the body 3, the cooling chamber 1 has a double structure in which the cooling chamber 1 is built in the external container 2, and is a relatively short desk or tabletop butts. In the receiving device, smoke components and odors are effectively prevented from leaking, and an appropriate beautification purpose or the like is achieved in the outer container 2. Further, a hanging metal fitting 13 is provided in the inner container 1 to facilitate cleaning by taking out.

The above-mentioned funnel 3 is elastically engaged and sealed to the outer container 2 and the circumferential edge 11 formed at the top end of the inner container 1 serving as the cooling chamber. In order to prevent the funnel 3 from being detached from the external container 2 and the cooling chamber 1 even when the butts are laid down, the funnel 3 is housed. It makes sense that things are scattered.

The above-described discharge port 30 is provided in the discharge tube 3.
0a, and even if the discharge tube 30a has a curved bottom surface 33, it can be easily mass-produced by a method in which a press formed as a divided body is opposed and welded. Can be easily manufactured by the conventional technique, and the whole manufacturing and assembling is easy.

The lower end portion of the discharge tube having an open end 34 formed to protrude to the side of the discharge tube 30a is connected as a cast member formed separately from the discharge port 30 formed in the funnel member 3. As a result, the discharge tube 30a can be easily manufactured as a roll-formed body using a relatively thin layer material, and the discharge port portion has high durability as a cast part, and preferably projects to the side of the discharge tube 30a. The cigarette receiver according to the present invention, which has a fire extinguishing function and a cigarette releasing function, is easy to manufacture and has high durability, can be manufactured and assembled at a low cost and simply.

According to the present invention, a relatively large inlet 3
In the case where 0 is used, it is preferable that the curved bottom surface 33 and the opening 34 described above are further protruded to the side of the inlet 30 as shown in FIG. That is, even if the opening 34 protruding to the side is a large-diameter opening 34, the rising smoke flow b rising from the lower part of the cooling chamber 1 is supplied to the inlet 30.
Is further restricted than in the case of FIGS.

Further, in the present invention, the curved bottom surface 33 as described above is used.
As shown in FIG. 4, the connection discharge pipe 36 is die-cast as a separate body, as shown in FIG. That is, the input port 30 is a cutting component body formed by a cut surface orthogonal to the axis as in a general funnel, and the lower end of the input port 30 is received and connected to the connecting portion 35, and the curved bottom surface 33 and The opening 34 can be easily formed by a cast body.

A specific example of the experiment using the large-diameter inlet 30 as described above will be described. The cooling chamber 1 is a steel cylinder having a diameter of 145 mm and a height of 300 mm.
The input port 30 as shown in FIG. 3 has a relatively large diameter of 38 mm and a length of 150 mm.
It was manufactured as an opening that protruded 10 mm from the side surface of No. 0. That is, to the buttress receiver of the present invention, a specially ignited 15 cigarettes were ignited at the same time and fire extinguishing and smoking were examined. However, no leakage of smoke was found outside the cooling chamber 1. The funnel 3 was removed two minutes after the introduction, and the fire extinguishing state was examined. However, it was confirmed that all butts were completely extinguished.

It should be noted that the apparatus according to the present invention as described above is provided with the cooling chamber 1 as shown in FIG.
I will perform the input deposition around the bottom outer peripheral part of the
As the buttocks are gradually deposited from the bottom, the surface of the buttocks deposited layer moves to the upper layer of the cooling chamber 1. However, since the butts 7 are released from the vertical openings 34, the outer periphery of the openings 34 is increased. Dropping in the direction, and the smoke rises from the fall position.
There is essentially no drain from zero.

Therefore, the device according to the present invention can be used for the purpose of receiving or extinguishing the butts 7 up to the vicinity of the above-mentioned opening 34, and can smoothly achieve the purpose of extinguishing fire extinguishing of a large number of butts such as several hundreds. it can.

[0031]

According to the present invention as described above, the bottom surface of the discharge port in the funnel-shaped member is curved to form a vertical or inclined discharge port with a protruding bottom. It regulates the direction of discharge of the butts in the cooling chamber, and also properly prevents smoke and other ingress from the butts from entering the outlets, effectively achieving convection and stagnation in the cooling chamber, and smoothly achieving the preferred dry fire extinguishing. However, since the fire extinguishing process for a relatively large amount of butts can be performed easily and smoothly, the invention is industrially highly effective.
