Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to a smoking water pipe that allows cigarette smoke to pass through water and be sucked out.

(Prior Art) Conventionally, water pipes generally include a cigarette insertion part and a tobacco suction port in a casing, and a smoke conduit that communicates with the cigarette insertion part extends to the inner bottom of the casing, and is placed above the water level in the casing. By sucking out the smoke from the smoke outlet from the position, the smoke from the cigarette inserted into the cigarette insertion part passes through the water in the casing and is guided to the smoke outlet, and in this process water-soluble components such as nicotine are dissolved and removed in the water. This is done to obtain a mild taste.

However, in conventional water pipes, the smoke introduced into the smoke conduit is discharged directly into the water from the lower end opening, resulting in considerably large air bubbles and the smoke is smoked without sufficiently dissolving and removing nicotine, etc. Furthermore, the main purpose of conventional water pipes is to dissolve and remove nicotine in water, and so-called tar contained in smoke along with nicotine and the like could hardly be removed. Furthermore, the conventional water pipe has a drawback in that when the casing falls down, the water inside leaks out from the cigarette insertion port and the suction port.

(Problems to be solved by the invention) This invention was developed in view of the above-mentioned circumstances, and is capable of sufficiently removing tar as well as nicotine, etc., and which does not cause water leakage even if the casing collapses. The purpose is to provide pipes.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes a casing 1 that is filled with water, and a thick lid that covers the casing watertightly and detachably. body 2
The lid body 2 is provided with a cigarette insertion port 3 and a cigarette suction port 4 that communicate with the inside of the casing, respectively, and a smoke conduit that communicates with the cigarette insertion port 3 and extends to the lid body 2 near the inside bottom surface of the casing. A filter tip 6 is inserted into the smoke pipe 5, and a check valve 7 is installed at the lower end of the smoke pipe 5 to normally seal the smoke pipe 5 and to open the smoke pipe during smoking.
is removably attached, and the cigarette inlet 4
, an elastic body 9 having a flue 8 is built in so that its tip slightly protrudes from the lid body 2, and a pipe portion corresponds to the tobacco suction port 4 and comes into elastic contact with the elastic body 9; 10 is rotatably pivotally attached to the lid body 2.

(Example) In Fig. 1, 1 is a casing made of glass, synthetic resin, etc., approximately the size of a cigarette case, with an open top, and the inside is filled with water up to about the middle of the casing. . Reference numeral 2 is a thick lid made of synthetic resin, which has a circular hole-shaped cigarette insertion opening 3 that opens on one side and communicates with the inside of the casing, and a corresponding opening on the other side that also has a hole inside the casing. A communicating tobacco outlet 4 is bored, and a watertight ring 11 is fitted to the outer peripheral surface of the lid 2 to cover the casing 1 in a watertight and removable manner. A bottomed smoke conduit 5 made of stainless steel or synthetic resin is connected to the cigarette insertion port 3 and is provided in the lid body 2.
are connected, and their lower ends hang down near the bottom inside the casing. A cap member 12 is fitted to the upper end of the smoke pipe 5, and an orifice hole 13 is formed in this, and a plurality of ventilation holes 5a are bored at the bottom of the lower end, as shown in FIG. A check valve 7 made of rubber or soft synthetic resin, which is formed into a disk shape and has a protrusion 7a in the center, is fitted to the bottom of the smoke pipe 5, and the check valve 7 normally controls the ventilation hole 5a. is blocking the Further, the tobacco suction port 4 has a smoke passage 8 in the center thereof for passing smoke,
The substantially thick ring-shaped elastic body 9 has a tip end surface 9a formed into a slightly arcuate surface, a rear end outer periphery formed in a step shape, and an O-ring 18 fitted thereto. The elastic material is preferably a soft synthetic resin such as vinyl chloride. A bearing portion 14 is provided in a protruding manner on the lid body 2 in correspondence with the tobacco suction port 4.
A pipe portion 10 is rotatably connected to this by a shaft 15 so that the tip end surface 10a always presses the elastic body 9. Note that the distal end surface 10a of the pipe portion 10 is formed in a convex circular arc shape, and the corresponding outer wall 2a of the lid body is formed in a convex circular arc shape. It is designed to be able to rotate while elastically contacting an elastic body 9 that extends slightly along the outer wall 2a and projects slightly. Furthermore, a stopper 17 is provided on the tip end 10a of the pipe section 10 to prevent further rotation when the pipe section 10 is extended, and when the pipe section 10 is folded (FIG. 2), the pipe section 10 closes to the casing. A recess 16a is formed in the former so as to closely align with 1.
However, a protrusion 16b is formed on the latter.

Fig. 1 shows the state during smoking, where smoke from a cigarette T inserted into the cigarette insertion port 3 is introduced into the smoke pipe 5, compressed through the orifice hole 13, and passes through with an increased flow velocity. At this point, the filter tip 6 is expanded and tar remains attached to the filter tip 6 inserted into the smoke pipe 5, and the check valve 7 is opened from the lower end vent hole 5a of the smoke pipe 5, allowing small particles to be submerged in the water. The tobacco is discharged as bubbles a, and after water-soluble components such as nicotine contained in the smoke are dissolved and removed in the water, the tobacco is naturally smoked from the pipe portion 10 through the tobacco suction port 4. Note that during smoking, the elastic body 9 is in elastic contact with the distal end surface 10a of the pipe portion 10, so that the pipe portion 10 is airtightly connected to the flue 8, and smoke does not leak to the outside during smoking. There isn't.

If the water or filter inside the casing 1 becomes dirty due to smoking, remove the lid 2 from the casing 1, replace the water, and replace the smoke conduit with the lid 2.
At the same time, the cap member 12 is removed from the smoke pipe 5, and the filter tip 6 inside is replaced.

FIG. 2 shows a state in which the pipe part 10 is not in use, and the pipe part 10 is folded along the side surface of the casing 1 around the shaft 15, and even in this case, the tip surface 10a of the pipe part 10 is connected to the elastic body 9. Since the folded state is reliably maintained,
This prevents water from leaking, and furthermore, the check valve 7 at the lower end of the smoke pipe 5 closes the bottom of the smoke pipe 5, preventing water from leaking from the cigarette insertion opening 3. do not have.

(Effects) According to the present invention, harmful components contained in smoke are removed by dry tar removing action by the filter tip 6 inserted into the smoke conduit 5 and wet dissolving action of water-soluble components such as nicotine by the water in the casing 1. can be removed efficiently.

Further, according to the present invention, when smoking, the pipe portion 10
is in elastic contact with the elastic body 9 on the lid 2 side, so the flue 8 on the lid side and the pipe section 10 are airtightly connected to prevent smoke leakage, and the pipe section 1
Even when folded, it is in elastic contact with the elastic body 9 and maintains its folded state reliably, prevents water from leaking, and is compact and convenient to carry.

Further, when not in use, the tobacco suction port 4 penetrating through the lid body 2 is blocked by the tip 10a of the pipe portion 10, and the smoke conduit 5 leading to the tobacco insertion port 3 is blocked by the check valve 7. Therefore, water will not leak even if the casing 1 falls sideways.
