Description

The present invention relates to a smokeless smoking device that is easier for smokers to use by further improving the smokeless smoking device.

Aikos, which Philip Morris launched in Japan in 2014, and Glow, which BAT launched in Sendai City in 2016, are said to be heat-not-burn tobacco and are selling very well. These cigarettes are made from chemically treated tobacco leaves that emit smoke when heated, and are finished in a shape similar to that of cigarettes with a filter. It is finished in a shape that is different in thickness and length from the rolled cigarette. The cigarette for Aikos is called heat stick and has a length of about 7.2φ and about 45 mm, and the cigarette for glow is called Neostec and has a length of about 5.2φ and a length of about 83 mm. The filter section of these cigarettes is made in a squid to carry nicotine generated by heating tobacco leaves and smoke to the smoker's mouth without absorbing it.
The smokeless smoking device using the cigarette cigarette heat stick for Philip Morris's Aikos disclosed as Example 3 in Patent Document 1 can smoke and smoke, and therefore, in a place where smoking is possible, Smoke smoking. It is very popular because you can smoke smokelessly in non-smoking areas.

Japanese Patent Application No. 2016-039568

Aikos and Glow have a mechanism to hold the heat stick and neo stick when the heat stick and neo stick are inserted into the holder and the main body, so the smoker sucks from the filter part of the cigarette. However, since the smokeless smoking device disclosed as Example 3 in Patent Document 1 does not have a mechanism for holding the cigarette, Patent Document 1
As shown in FIG. 6 inside, the entire cigarette is put into the guide tube A and sucked from the mouthpiece.

For this reason, nicotine and smoke generated by heating the cigarette part of the cigarette pass through the route of the filter part ⇒ spacer ⇒ tip part C ⇒ mouthpiece ⇒ smoker's mouth.
It is carried to the smoker's mouth, but the air between the rolled paper of the cigarette and the guide tube A also enters through the spacer and is carried to the smoker's mouth, so that the generated nicotine and smoke are diluted. There's a problem.

Furthermore, when smoking is continued with the smokeless smoking device, the generated nicotine adheres to the wall surface inside the smokeless smoking device, and the heat of the heater during smoking causes these adhering substances to re-evaporate during smoking. It has been found that the taste of nicotine is deteriorated, but since it cannot be disassembled and cleaned, the inside is cleaned with a cotton swab or the like, but there is also a problem that these adhering substances cannot be completely removed.

Furthermore, the heater for heating may also be disconnected during use, and in such a case, there is a problem that the smokeless smoking device must be disassembled and the heater replaced by returning it to the manufacturer.

FIG. 1 is an axial sectional view of the smokeless smoking device 100 according to the first embodiment of the present invention. In the smokeless smoking device 100 of the first embodiment, a cigarette holding tube 78 is newly attached to the spacer 111.

FIG. 2 is an axial sectional view of the smokeless smoking device 100 according to the second embodiment of the present invention. The smokeless smoking device 100 of the second embodiment incorporates a newly devised cigarette holding mechanism 93, a removable heating cylinder portion 91, and a removable heater portion 92.

Explanatory drawing of how to assemble smokeless smoking equipment of Example 2 Axial cross-sectional view of a mouthpiece with a tobacco leaf filling Axial sectional view of smokeless smoking device disclosed as FIG. 6 in Patent Document 1.

FIG. 8 is an axial sectional view of a conventional smokeless smoking device 100 disclosed as Example 3 in Patent Document 1. The smoker pulls out the guide tube A118 with the end component B108 to the point where it stops at the guide tube B6. Next, the heat stick 68 is inserted into the guide tube A118 with the cigarette portion at the head, and the spacer 111, the tip component C119, and the commercially available mouthpiece 53 are integrated (hereinafter referred to as the mouthpiece portion). Is inserted into the guide tube A118 and inserted into the main body. As a result, the heater 131 is inserted into the substantially center portion of the cigarette portion of the heat stick 68. The smokeless smoking tool 100 includes a rechargeable battery 29, a rechargeable battery holder 9, a USB receptor 26 that receives a charging voltage, a charging display LED 27, a power supply SW28, a charging circuit unit, a main printed board 31, a switch 22, a display 136, a button 30, and a battery. Part connection part 24, terminal part 102
, The outer tube 104, and the tip component 101. Since these are described in detail in Patent Document 1, they will be omitted here. When the power supply SW28 is turned on in this state, a controlled voltage is supplied to the heater 131 from the microcomputer mounted on the main printed circuit board 31, and the heater generates heat. As a result, the cigarette portion of the heat stick 68 is heated, nicotine and smoke are generated, and the smoker can suck these from the mouthpiece. However, it was found that the air in the space created by the outside of the heat stick 68 and the inside of the guide tube A118 flows from the tip of the spacer 111, dilutes nicotine and smoke, and dilutes these tastes.

FIG. 1 is an axial sectional view of the smokeless smoking device 100 of the first embodiment of the present application, which has been proposed to improve the above problems. In the cross section, the cigarette holding tube 78, which is fitted with the spacer 111, is shown.
It has been newly added. Since the outer diameter of the cigarette holding tube 78 is smaller than the inner diameter of the guide tube A118, and the inner diameter thereof is made very slightly larger than the outer diameter of the heat stick 68 to be inserted, the heat stick 68 is the cigarette holding tube. It is inserted into the inside of the 78 with almost no gap.

The heat stick 68 is inserted into the cigarette holding tube 78 that is fitted with the spacer 111, and this is inserted into the smokeless smoking device together with the guide tube A118 of the smokeless smoking device 100. When the power supply SW28 is turned on in this state, the heater 131 is heated by the controlled voltage from the microcomputer mounted on the main printed circuit board. As a result, the tobacco portion of the heat stick 68 is heated, and nicotine and smoke are generated. In this state, the smoker has a commercially available mouthpiece 5
When sucked from 3, the nicotine and the smoke are carried to the smoker's mouth, but due to the adoption of the cigarette holding tube 78, the air outside the wrapping paper of the heat stick 68 is almost in the smoker's mouth. It wasn't carried and it no longer dilutes the taste of nicotine and smoke.

FIG. 2 is an axial sectional view of the smokeless smoking device 100 according to the second embodiment of the present application. This smokeless smoking tool 100
Is a smokeless smoking device that enables direct suction from the filter portion of the heat stick 68 without using a mouthpiece portion, and the smokeless smoking device can be disassembled and cleaned.

The major differences from the conventional smokeless smoking device 100 and the smokeless smoking device 100 of the first embodiment of the present application are as described below.
1) As shown in FIG. 6, the outer pipe 104 is separated into the outer pipe A107 and the outer pipe B105.
However, the outer tube 104 of the conventional smokeless smoking device is also made by laminating two semicircular resin parts into a tubular shape, but since the two semicircular resin parts are adhered to each other, the two semicircular resin parts are adhered to each other. There is no separation between the two parts.
2) There is no mouthpiece part, and the tip part 101 is the tip part A109 and the tip part B110.
, P plate F17, screw 74, and spring 20 are assembled into a cigarette holding mechanism 93.
3) Furthermore, there is no guide tube A118, instead, the inner tube 5, P plate B11, P plate C12, P plate D.
A heating cylinder portion 91 composed of a pedestal 33 and a pedestal 33 is incorporated.
4) Further, a heater unit 92 composed of a P plate A10, a heater 131, a pin C58, and a pin D59 is incorporated.
5) Further, the heater unit 92 includes pins A18 and pins B1 mounted on the main P plate 31.
By connecting 9, pin C58, and pin D59 with connectors (not shown), respectively.
Power is supplied from the main P plate to the heater 131.

FIG. 6 is a partial view illustrating the configuration of the smokeless smoking device 100 according to the second embodiment of the present application. FIG. 6A shows an outer tube B105 and a terminal part 102 having a stopper 8 integrated with an adhesive, which is further integrated with a rechargeable battery holder 9 with an adhesive. Further, the rechargeable battery holder 9 incorporates a charging circuit section and a main circuit section, and is covered with a battery section connecting portion 24. A predetermined position of the outer tube B105 in this state (not shown, but inside the outer tube B105, FIG. 4
A recess is made so as to place the heater portion 92 and the heating cylinder portion 91 shown in the above in a predetermined place. ), The heater portion 92 and the heating cylinder portion 91 are placed, and the pin A18, the pin C58, and the pin B19 are placed.
After connecting the pin D59 and the pin D59 electrically using a connector, the outer tube A shown in FIG. 6 (B).
The 107 and the cigarette holding mechanism 93 are fixed to the rechargeable battery holder 9 with the screw 74. What, screw 7
The nut that receives 4 is attached to the P plate D16 that receives the + electrode of the rechargeable battery. The hole 1 is a hole for taking in outside air, and when a smoker sucks from the filter part of the inserted cigarette, the air pressure in the smokeless smoking tool drops, and the outside air is taken into the jig from this hole 1. Inner tube 5
While cooling the outside of the P-plate B11, it enters the inside of the inner tube 5 and is carried to the smoker's mouth together with the generated nicotine and smoke.

From the above structural explanation, the smokeless smoking tool 100 of the second embodiment of the present application can be obtained by removing the screw 74.
The outer tube A107 and the cigarette holding mechanism 93 shown in FIG. 6B can be easily removed, and the heating cylinder portion 91 and the heater portion 92 inside can be taken out. It is not necessary to explain that it is possible to completely clean them by this. Furthermore, at least the outer tube A107 is made of a transparent material.
For example, if it is made of transparent ABS resin or the like, the state of the internal heating cylinder portion 91 and the heater portion 92, and the state of the heater portion 92, etc.
The degree of dirt inside the jig can be seen from the outside, which makes it easier to use. In FIG. 6B, the outer tube A107 and the cigarette holding mechanism 93 are fixed and integrated with an adhesive, but the cigarette holding mechanism 93 is like a stopper 8 of a terminal component 102. The outer tube A107 and the cigarette holding mechanism 93 can be manufactured as separate parts without being bonded to each other. In this case, the outer tube A107 can be removed by removing the screw 74 and the cigarette holding mechanism 93.

Next, the cigarette holding mechanism 93 will be described. In this mechanism, the heat stick 68 inserted in the smokeless smoking device 100 is placed under the P plate F17 so that the heat stick 68 does not come out of the smokeless smoking device 100 during smoking. It is a mechanism that holds down with the force of. FIG. 3A is a perspective view seen from substantially the left side of the tip component A109. The substantially oval P plate F storage portion 2 is dug. When the P plate F17 shown in FIG. 3B (in the present application, the P plate F17 is made of the P plate, but a resin part having the same shape may be used) is inserted in the P plate F17 storage portion 2. The P plate F17 is made to move c + d (0 <d <c) in the vertical direction. Further, a cigarette insertion hole 3 through which the heat stick 68 passes is formed substantially in the center thereof. Since the outer diameter of the heat stick is about 7.2 mmφ, the diameter of the hole 3 is set to 7.5 mmφ so that it can be easily inserted when the heat stick is inserted. P plate F shown in FIG. 3 (B)
A hole 7 is formed in 17. FIG. 3C illustrates the shape of the hole 7.
The hole 7 shown in the figure is in the state of a = b = 3.75 mm and c = 0.6 mm in (C). When the P plate F17 is incorporated into the P plate F storage portion 2 together with the spring 20, the P plate F17 is the spring 2
When the center of the hole 3 and the center of the radius b are aligned with each other by being pressed upward by the force of 0, the hole 2 and the P plate F17 are designed so that a gap d is formed at the upper part. By designing in this way, when the P plate F17 is pressed above the P plate F insertion portion 2 by the force of the spring 20, the hole created by the cigarette insertion hole 3 and the elongated hole 7 of the P plate F The upper half is a semicircle with a radius of 3.75 mm, and the lower half is a composite of a semicircle with a radius of 3.75 mm moved upward. It is not necessary to explain that this shape becomes a circle with a radius of 3.75 mm when the protrusion 41 is pushed in with a finger.
When a heat stick is inserted into a circle having a radius of 3.75 mm formed by pushing the protrusion 41 with a finger and the finger is removed, the P plate F17 is moved upward by the force of the spring 20 and has a radius. The circle of b holds down the heat stick so that the heat stick does not come out. In FIG. 3 (c), the semicircle b is, for example, the outer diameter of the heat stick to be inserted about 7.
It was experimentally confirmed that the force for pressing the inserted heat stick was increased by the circle having the radius b by making the hole 7 the same as or slightly smaller than 2 mm. It is clear that this mechanism can be applied not only to heat sticks but also to commercially available cigarettes of about 8φ and cigarettes of about 5.2 mmφ for glow by changing the design dimensions of the elongated holes.

Next, the heating cylinder portion 91 shown in FIG. 4 will be described. This part consists of 3 P plates and 5 inner pipes.
It is composed of (AL tube or glass tube). The inner diameter of the inner pipe 5 is made to be the outer diameter of the heat stick 68 + 0.1 to 0.2 mmφ. The P plate D13 and the P plate C12 are drilled with a hole slightly larger than the outer diameter of the inner pipe 5, and the inner pipe 5 is made to fit tightly into this hole. Alternatively, the P plate D13 and the P plate C12 can each be made of two P plates. In this case, the hole of the P plate constituting the left side of the P plate C12 is much smaller than the outer diameter of the inner pipe 5, and the hole of the P plate constituting the right side is slightly larger than the outer diameter of the inner pipe 5, P. The hole of the P plate constituting the left side of the plate D13 is slightly larger than the outer diameter of the inner pipe 5, and the hole of the P plate constituting the right side is made substantially the same as the outer diameter of the heat stick, so that the inner pipe 5 is formed. It can also be made so that it does not come off. P board B
A hole 38 through which the heater 131 passes (this hole also has a role of allowing the outside air taken in from the hole 1 to flow into the inner pipe 5) is formed in the eleven at a substantially center position. Further, two pedestals 33 having screw holes are fixed up and down so that the heater portion 92 can be attached and fixed. The P plate C12 and the P plate B11 are adhered to each other. Further, two to four pins may be set between the P plate D13 and the P plate C12 to prevent the positional relationship between the two from moving.

Next, the heater unit 92 shown in FIG. 4 will be described. Since the smokeless smoking device uses a rechargeable battery as a power source, it is necessary to reduce the heat capacity of the heater itself as much as possible in order to raise the heater temperature to 200 ° C. or higher. The heater unit 92 includes a pin C58 that receives power from the P plate A10 and a pin C58.
A pin D59 is attached, and a screw hole 34 for fixing the heater portion 92 to the heating cylinder portion 91 is drilled. The slit 35 inserts and solders a lug terminal forming one electrode of the heater 131. An axial sectional view of the heater 131 attached to the P plate A10 is shown in FIG. In order to reduce the heat capacity of this heater 131,
An AL tube with a thin surface oxide film is used, and the electrical connection between the nichrome wire or Kanthal wire and the lead wire of the heater is devised. In FIG. 5A, the AL tube 81 has an outer diameter of 1.3φ, a wall thickness of 0.07 mm, and a length of 16 mm, and has an insulating oxide film formed on the outer surface. Copper tape 8 with a width of 3 to 4 mm and a thickness of 0.1 mm, leaving 1 mm from the left end of the AL tube 81.
Wind 4 In practice, although not shown, ultra-thin heat resistant tape is wrapped to ensure insulation between the copper tape and the AL tube with surface oxide film. Next, 0.6φ, length = 23
In the right tip of the mm brass wire or phosphor bronze wire 86, in the insertion hole of the fastener 83 (specifically, AF-0.5 (H) -B commercially available under the name Socket-kun), nichrome wire or Cantal line 82
By passing through the brass wire or the phosphor bronze wire 86, an electrical connection between the two is made.
Further, in order to make the electrical connection more reliable, the connection portion is soldered with lead-free solder having a melting point of 226 ° C. Next, the nichrome wire or cantal wire 8 connected and fixed at the tip.
2 is wound around the AL tube in a coil shape, and the end is also wound on the copper tape 84. In this state, the connection between the two is made only by contact, and only a very unstable connection is made. Therefore, in order to ensure the electrical connection between the two, eyelets (inner diameter of about 1) from the right side.
.. By sliding the 7 mmφ) 85 onto the copper foil, the nichrome wire or the cantal wire 82 is pressed against the soft copper tape 84, and the electrical connection becomes more reliable. Further, the lug terminal 87 processed as shown in FIG. 5B is passed through an eyelet and fixed with solder to form one lead wire of the heater 131. The other lead wire 86 is AL.
It passes through the tube 81 and extends to the left side of the heater 131 to become the other lead wire. In addition, the fastener 83 at the tip and the brass wire or phosphor bronze wire are soldered using lead-free high-temperature solder having a melting point of 226 ° C. to further secure the connection with the nichrome wire or the cantal wire. Further, with the same solder, the solder is also poured between the eyelet and the copper tape to further secure the connection between the nichrome wire or the cantal wire and the eyelet or the copper tape. Furthermore, by using copper tape, even if the outer diameter of the AL tube and the inner diameter of the eyelet are different, it can be dealt with by changing the number of turns of the copper tape.

By the structure and method described above, the heat capacity of the manufactured heater 131 became very small, and the heater temperature could be sufficiently raised to 200 ° C. or higher even with the power of the rechargeable battery. Normal,
Nichrome wire and cantal wire cannot be connected to the leader lead wire by welding (because the resistance value of the welded part rises, the temperature of that part rises abnormally, and the wire breaks), so screws and caulking will occur. Although they are used, when they are used, their heat capacities are large, and the surface temperature of 200 ° C. or higher cannot be obtained with the electric power from the rechargeable battery. However, as described above, the combined use of pressure welding and high-temperature solder enables a connection with a small heat capacity. This structure is the same as that of the heater 131 used in the smokeless smoking device of the first embodiment.

As shown in FIG. 4 heater unit 92, the heater 131 made as described above has the P plate A10.
Attached to. The brass wire or phosphor bronze wire 86 of the heater 131 and the lug terminal 87 are electrically connected to the pins C and D on the P plate A10, respectively.

As is clear from the above description, the smokeless smoking device 100 of Example 2 has no mouthpiece.
Even if you smoke from the filter part of the inserted heat stick 68, the cigarette holding mechanism 93 proposed in the present application prevents the smokeless smoking device from coming out, and the part to which nicotine generated during smoking adheres is completely decomposed. -It is clear that it can be taken out, cleaned cleanly and reassembled. Furthermore, it is not necessary to explain that the heater can be easily replaced.

FIG. 7 is an axial sectional view of a mouthpiece 94 having a tobacco leaf filling portion used in combination with the smokeless smoking tool 100 of the second embodiment of the present application. With the recent spread of heated tobacco such as Aikos and Glow, some smokers end up impregnating tobacco leaves with smoke-producing e-cigarette liquids (such as glycerin), which are usually It seems that it is beginning to be understood that if you take out the tobacco leaves from the cigarette, sprinkle with liquid, and heat the tobacco leaves, you can get nicotine, smoke, and smoke. It is becoming widespread that such smoking methods are cheaper. Therefore, a mouthpiece 94 having a tobacco leaf filling portion having the structure shown in FIG. 7 was devised. 53 is a mouthpiece commercially available under the name Select 25. Reference numeral 15 is a tubular portion made of molded resin, which connects the mouthpiece 53 and the AL tube A14.
Parts to fix. Reference numeral 14 is a thin-walled AL tube having an outer diameter of about 7.5 mmφ (almost the same as the outer diameter of the cigarette heat stick for Aikos). Smokers loosen the tobacco leaves of a cigarette with a filter,
After filling the tobacco leaf filling portion 36, a few drops of glycerin or the like are dropped, and after leaving it for a while, a mouthpiece having the tobacco leaf filling portion and a heat stick 68 are inserted into the smokeless smoking tool 1.
Insert at 00. Due to the cigarette holding mechanism 93, the mouthpiece does not come out of the smokeless smoking device. By the insertion, the heater 131 is inserted almost in the center of the tobacco leaf, the tobacco leaf is heated, and nicotine and smoke are evaporated, so that the smoker can suck from the mouthpiece 53.

By attaching a cigarette holding mechanism to the conventional smokeless smoking equipment, it has become possible to suck from the inserted heat stick filter part without using a mouthpiece. Furthermore, by placing the heating cylinder part and the heater part in the outer tube composed of two parts, it becomes possible to disassemble and clean it, and it is possible to prevent the taste from deteriorating when smoking due to the adhesion of evaporated nicotine.
