Description

The present invention relates to a smoking device in which a cigarette is heated by a heater to smoke.

Conventionally, smoking ignites tobacco leaves, vaporizes components such as nicotine and tar contained in the tobacco leaves during combustion (aerial dispersion particles or fumes), and inhales them. It has been pointed out that this conventional smoking practice has the harmful effect of passive smoking by people around it because substances harmful to the human body become smoke and stay in the room when the tobacco leaves and their wrapping paper are burned.

Therefore, in recent years, without igniting the tobacco leaves, the tobacco leaves or substances containing suction components contained in the tobacco leaves (here, these are collectively defined as "tobacco") are heated by an electric heater. Smoking tools that vaporize this suction component are becoming widespread. According to this, since the tobacco leaves and the rolling paper do not burn, the harmful effects of second-hand smoke are reduced.

In this type of smoking equipment, a heater for heating is arranged inside the tubular member, and when the cigarette is inserted into the tubular member, the heater pierces the tip of the cigarette in the axial direction. .. When the leaves of cigarettes are heated by this heater, nicotine and the like are vaporized and can be sucked. A sliding cylinder for pulling out the cigarette after the suction is completed is arranged on the inner peripheral side of the tubular member, and the sliding cylinder holds the cigarette. When this sliding cylinder is pulled out from the tubular member, the sliding cylinder and the cigarette cigarette are interlocked and forcibly separated from the heater. Since the integrity of the cigarette is maintained in the sliding cylinder at the time of withdrawal, it is possible to prevent a part of the cigarette from being cut off and remaining (see Patent Document 1).

Patent No. 6050826

Conventional smoking equipment has the following problems.

(1) Even if a sliding cylinder is present, cigarette burnt residue, burnt residue, leaf debris, etc. gradually remain around the heater. However, it is difficult to clean the residue because the structure is such that the heater and the like cannot be disassembled.

(2) If the circumference of the heater is scratched with a stick or the like for the purpose of cleaning, the heater has a structure that is easily broken, so that there is a problem that the heater is easily broken. In that case, only the heater cannot be replaced, so there is no choice but to repurchase the smoking equipment itself. Similarly, since the heater is made of ceramic, it will break instantly due to rapid cooling when it is exposed to moisture such as rain or sweat in a high temperature state immediately after smoking. Even in that case, there is a problem that there is no choice but to repurchase the smoking equipment itself.

(3) Since the assembly structure of the heater, the battery for heating the heater, the circuit board for voltage control, and the like is complicated, there is a problem that the manufacturing cost increases.

(4) The residue accumulated around the heater hinders the reciprocating movement of the sliding cylinder. As a result, the paper-wrapped cigarette is inserted and sucked in a state where the sliding cylinder is not sufficiently pushed in, and the heating by the heater tends to be insufficient.

(5) When smoking is repeated, stress is applied to the heater due to contact with the cigarette, and the heater, the heater holding portion, and the like may be deformed (displaced). As a result, when the heater interferes with the sliding cylinder, the heater is easily broken by the manual operation of the sliding cylinder. In particular, when the heater is in the shape of a metal rod, the heater is easily bent.

(6) The sliding cylinder tends to get hot. Therefore, it is dangerous for smokers to pull the hot sliding cylinder toward you with the cigarette.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 show the overall configuration of the smoking device 1 according to the first embodiment of the present invention. The smoking tool 1 is arranged inside the holding cylinder 10 and the holding cylinder 10 in which the cigarette is inserted from the front end side to the rear end side, and extends in the axial direction of the holding cylinder 10 to heat the cigarette. 20 The substrate 50 accommodated on the rear end side inside the holding cylinder 10, the front side engaging portion 78 fixed inside the holding cylinder 10 and engaged with the stopper portion 30, and the shaft with respect to the heater portion 20. It has a cleaning unit 40 and the like that are arranged so as to be reciprocally movable in the direction.

<Holding cylinder>

As shown in FIG. 4A, the holding cylinder 10 has a substantially cylindrical shape here, and has a front end opening 10A and a rear end opening 10B. On the inside, the front end side is the cigarette accommodating space 10C for accommodating the cigarette, and the rear end side is the substrate accommodating space 10D for accommodating the substrate 50. Further, between the cigarette accommodating space 10C and the substrate accommodating space 10D, there is a heater portion mounting space 10E in which a part of the heater portion 20 extends.

The holding cylinder 10 includes an engaging portion regulating step portion 12 formed so that the inner wall is radially inwardly reduced in diameter in the vicinity of the tip opening 10A. The engaging portion regulating step portion 12 has an engaging surface 12A facing the rear end side, and another member (cleaning portion stopper 48 or inner cylinder 70) that directly engages with the engaging surface 12A is interposed therein. However, it finally engages with the front side engaging portion 78 in the axial direction. As a result, the front side engaging portion 78 cannot move to the tip side in the axial direction.

On the inner wall of the substrate accommodating space 10D in the holding cylinder 10, a pair of slit-shaped substrate recesses 14 extending in the axial direction are formed so as to substantially face each other in the radial direction. By inserting both end edges of the substrate 50 in the width direction into the pair of substrate recesses 14, the substrate 50 is positioned in the circumferential direction in the substrate accommodation space 10D (see FIG. 1D). A positioning surface 14A is formed at the inner end of the recess 14 for the substrate, and the substrate 50 is positioned on the distal end side in the axial direction by bringing the tip edge of the substrate 50 into contact with the positioning surface 14A. NS. When the substrate 50 is fixed at an offset in the radial direction from the axis of the substrate accommodation space 10D, the slit-shaped recesses 14 for the substrate are also formed so as to face each other at a position offset in the radial direction from the axis. It's fine. That is, the slit-shaped recesses 14 for the substrate may face each other along a predetermined string of the inner peripheral circle.

As shown in FIG. 4C, the holding cylinder 10 includes a rear end cap 80 that is removable with respect to the rear end opening 10B. Here, the rear end opening 10B is a female screw and the rear end cap 80 is a male screw, so that the two are connected by a screw fastening structure. The inner side surface (tip side surface) of the rear end cap 80 is a substrate regulating step portion 88 extending inward in the radial direction as compared with the rear end opening 10B. As shown in FIG. 1, the substrate restricting step portion 88 abuts on the rear end edge of the substrate 50 to restrict the substrate 50 from moving toward the rear end side in the axial direction. On the other hand, if the rear end cap 80 is removed, at least the substrate 50, the heater portion 20, and the like can be taken out from the rear end opening 10B of the holding cylinder 10. In this embodiment, all the internal parts including the inner cylinder 70 and the like can be taken out from the rear end opening 10B. Although the structure in which the rear end cap 80 is fastened to the holding cylinder 10 by a screw is illustrated here, another joining method such as a claw or press fitting may be used.

<Heater part, etc.>

As shown in FIG. 3B, the heater portion 20 is a strip-shaped plate extending in the axial direction, and the front end side is a heating region 22 having a high temperature, and the rear end side is a non-heating region 24 having a low temperature or a normal temperature. .. The heating region 22 is provided with a high temperature wiring element 22A inside or on the surface, which becomes hot when energized due to a high resistance value. In the non-heated region 24, a low temperature wiring element 24A having a lower resistance value than the high temperature wiring element 22A and hardly generating heat even during energization is provided inside or on the surface. The tip of the heater portion 20 is inclined so as to have an angle with respect to the direction perpendicular to the axis so that the tip of the heater portion 20 can be smoothly inserted into the inside of the tobacco leaf.

The stopper portion 30 is integrally arranged on the base end side of the heater portion 20. The stopper portion 30 constitutes a step that expands in the radial direction (at least one of the width direction and the thickness direction, and here, the width direction) with respect to the heater portion 20. The stopper portion 30 may be integrally formed of the same material as the heated region 22 and the non-heated region 24, or may be bonded, welded, and engaged with each other by a separate member from the heated region 22 and the non-heated region 24. It may be integrated. The front end side engaging surface 30A of the stopper portion 30 engages with the rear end side engaging surface 78B of the front end side engaging portion 78 via the elastic plate 16 (see FIG. 1). Further, a connection terminal portion 35 is provided on the rear end side of the heater portion 20 with respect to the stopper portion 30. The connection terminal portion 35 is composed of a plurality of metal pins extending in the axial direction. The connection terminal portion 30 is not limited to the metal pin structure, but is a socket structure in which a metal pin or a metal plate is combined inside or outside the male or female socket of the insulator, or a plate structure in which a metal electrode surface is formed on the surface of the insulating substrate. , Various terminal structures such as a fastening structure for fixing with a screw, a sandwiching structure for winding a wire or the like around a screw, a crimp terminal structure, and the like can be adopted.

<Board>

As shown in FIG. 3C, the substrate 50 includes a connector portion 52 which is arranged at the end edge on the tip side and into which a metal pin of the connection terminal portion 35 is detachably inserted, a temperature control circuit 53, and an outside. It includes a power receiving connector 54 that is connected and supplied with power, a switch 55, and an LED 56. The power receiving connector 54 is a USB standard (specifically, microUSB) connector here, and is connected to external power. The holding cylinder 10 is formed with a connector opening 11A for exposing the power receiving connector 54 to the outside (see FIG. 1B). The external power is preferably a DC power supply of about 5.0 V. The power receiving connector 54 is connected to a converter that converts a household AC power supply into a direct current, or is connected to an external battery, an external battery, or the like. Although not particularly shown here, a battery or a battery may be mounted inside the smoking tool 1. The temperature control circuit 53 controls the current and / or voltage supplied through the power receiving connector 54 to control the temperature of the heating region 22 of the heater unit 20. In the present embodiment, the heating region 22 is controlled to be stable within the range of 180 ° C to 240 ° C.

The switch 55 switches ON / OFF of heating by the heater unit 20. This operation is performed via the external operation unit 11B which is movably arranged in the holding cylinder 10 in the radial direction (see FIG. 1C). The LED 56 informs the smoker of the ON / OFF operating state and failure state of heating by turning on / blinking / turning off. The light of the LED 56 is emitted to the outside through the light transmitting portion 11C formed in the holding cylinder 10 (see FIG. 1C).

<Interenging part (inner cylinder) on the other side>

As shown in FIG. 1, the front side engaging portion 78 is composed of a part of a bottomed inner cylinder 70 arranged on the inner circumference of the holding cylinder 10. Specifically, as shown in FIG. 3E, the inner cylinder 70 is formed on a cylindrical cylinder portion 73 extending in the axial direction, a bottom portion 75 formed on the rear end side of the cylinder portion 73, and a bottom portion 75. Has an opening of 75A. The heater portion 20 is inserted into the opening 75A from the rear end side toward the front end side. It is preferable to have a gap (not shown) between the opening 75A and the heater portion 20. The gap can prevent the heat of the heater portion 20 from being transferred to the inner cylinder 70. The inner cylinder 70 is preferably made of a material having high heat insulating properties or heat resistance (for example, a material having high heat resistance such as polycarbonate or polypropylene). This is because the heat of the heated cigarette can be suppressed from being transferred to the holding cylinder 10.

The periphery of the opening 75A in the bottom portion 75 is the front side engaging portion 78. As shown in FIG. 1, the rear end side engaging surface 78B of the front side engaging portion 78 comes into contact with the tip end side engaging surface 30A of the stopper portion 30 via the elastic plate (elastic member) 16 (axial direction). Engage in). Therefore, the heater portion 20 is restricted from moving toward the tip end side by the stopper portion 30.

<Rear side engaging part, etc.>

Inside the holding cylinder 10, a rear side engaging portion 39 that regulates the movement of the heater portion 20 to the rear side is provided. In the present embodiment, the rear engaging portion 39 is realized by the connector portion 52. That is, the heater portion 20 is restricted from moving to the rear side by the connector portion 52. The movement restriction of the heater portion 20 by the connector portion 52 is not limited to the case where the stopper portion 30 and the connector portion 52 are engaged with each other. For example, the pin of the connection terminal portion 35 in the heater portion 20 is set to be longer, and the pin tip of the connection terminal portion 35 is set to the connector portion 52 before the stopper portion 30 or the like in the heater portion 20 engages with the connector portion 52. It also includes the case where the heater portion 20 collides with the bottom of the hole, which restricts the movement of the heater portion 20 to the rear side.

<Heater fixing structure>

Inside the holding cylinder 10, a heater fixing structure 15 is provided so that the heater portion 20 can be fixed in the axial direction at the time of assembly and the heater portion 20 can be opened at the time of disassembly. The heater fixing structure 15 of the present embodiment is composed of the front side engaging portion 78, the rear side engaging portion 39 (connector portion 52), the stopper portion 30, and the like, which have already been described. At the time of disassembly, if the front side engaging part 78 is removed to the tip side of the holding cylinder 10 or the rear side engaging part 39 (connector part 52) is separated from the heater part 20, the heater part 20 becomes independent. It can be opened and only the heater unit 20 can be replaced.

As shown in FIG. 3F, the elastic plate 16 is elastically deformable in the axial direction and is made of a heat insulating material. For example, the material of the elastic plate 16 is preferably silicone rubber or the like. The elastic plate 16 absorbs shape errors of various parts and members such as an outer dimension error of the substrate 50, an installation error of the connector portion 52, and a shape error of the stopper portion 30 due to its elastic deformation. The elastic plate 16 is not an essential configuration, and its installation location is not limited to this embodiment.

<Cleaning section>

As shown in FIG. 1, the cleaning unit 40 is arranged so as to be reciprocally movable in the axial direction while approaching or abutting on the outer peripheral surface of the heater unit 20. As shown in FIG. 3A, the cleaning portion 40 is a cylindrical member, and a groove-shaped through hole 44 is formed inside. The shape of the through hole 44 viewed from the axial direction is substantially the same as the shape of the heater portion 20 viewed from the axial direction, and the heater portion 20 is inserted into the through hole 44. As a result, the cleaning unit 40 approaches or comes into contact with the outer peripheral surface of the heater unit 20 and can reciprocate in the axial direction while sliding with the heater unit 20.

The outer diameter of the cleaning portion 40 substantially coincides with the inner diameter of the inner peripheral surface of the inner cylinder 70 (that is, the inner peripheral surface of the holding space for cigarettes). As a result, the cleaning unit 40 approaches or comes into contact with the inner peripheral surface of the inner cylinder 70, and can move back and forth while sliding in the axial direction. Therefore, the cleaning unit 40 also serves as a holding member that indirectly holds the heater unit 20 by interposing between the inner cylinder 70 and the heater unit 20.

On the tip surface of the cleaning portion 40, a first protrusion 40A having a saw-tooth cross section that is convex in the tip direction is formed along the edge of the through hole 44. The first protrusion 40A plays a role of scraping off the tobacco leaves adhering to the outer peripheral surface of the heater portion 20. Further, on the tip surface, a second protrusion 40B having a saw-tooth cross section that is convex in the tip direction along the outer peripheral edge is formed. The second protrusion 40B plays a role of preventing scorching and the like from entering the gap between the inner cylinder 70 and the cleaning portion 40, and scraping off tobacco leaves and rolling paper adhering to the inner peripheral surface of the inner cylinder 70. ..

The cleaning unit 40 is set so that the axial dimension L is the same as or larger than the diameter R. Further, except for the through hole 44, the cleaning portion 40 is a solid member. This solid portion becomes a weight region 42 having a desired weight, and the smoker vibrates the holding cylinder 10 in the axial direction to create inertia in the cleaning portion 40. As a result, the cleaning unit 40 reciprocates inside the holding cylinder 10 relative to the heater unit 20 and the inner cylinder 70.

A compression spring 60 serving as a urging means for urging the cleaning portion 40 toward the tip end is arranged between the rear end surface of the cleaning portion 40 and the bottom portion 75 of the inner cylinder 70. The compression spring 60 urges the cleaning unit 40 toward the tip side only in a part of the range on the base end side during the reciprocating movement stroke (movement stroke) of the cleaning unit 40. Specifically, when an external force other than gravity is not applied to the cleaning unit 40 (see FIG. 1), the compression spring 60 does not urge the cleaning unit 40. On the other hand, when the cleaning unit 40 is pushed to the back side (rear end side) by the inertial force of the cleaning unit 40, or when the cleaning unit 40 is pushed to the back side through the cigarette inserted by the smoker (FIG. 6 (FIG. 6). B)), the compression spring 60 is contracted, and the cleaning portion 40 is urged toward the tip side by its elasticity (repulsion).

As shown in FIG. 1, a cylindrical cleaning portion stopper 48 is installed between the inner cylinder 70 and the engaging portion regulating step portion 12 on the inner peripheral surface of the holding cylinder 10 (FIG. 3 (D). )reference). The inner diameter of the cleaning portion stopper 48 is set to be smaller than the inner diameter of the inner cylinder 70, and as a result, a cleaning portion regulating step portion 49 projecting inward in the radial direction is formed at the boundary between the two. By engaging the cleaning portion regulating step portion 49 with the tip surface of the cleaning portion 40 in the axial direction, one limit of the moving stroke of the cleaning portion 40 is defined. The other limit of the movement stroke of the cleaning portion 40 is defined by the rear end surface of the cleaning portion 40 engaging with the bottom portion 75 of the inner cylinder 70 via the contracted spring 60.

An elastic ring 18 is arranged between the stopper 48 for the cleaning portion and the step portion 12 for restricting the engaging portion (see FIG. 4B). The elastic ring 18 is elastically deformable in the axial direction and is made of a material having high heat resistance or heat insulating properties. Similar to the elastic plate 16, the elastic ring 18 causes an outer dimension error of the substrate 50, an installation error of the connector portion 52, a shape error of the stopper portion 30, the inner cylinder 70, the stopper 48 for the cleaning portion, and the like due to its elastic deformation. Absorb. The elastic ring 18 is not an essential configuration, and its installation location is not limited to this embodiment.

<How to assemble smoking equipment>

Next, a method of assembling the smoking tool 1 will be described. Since the disassembling method may be performed in the reverse procedure to the assembling method, the description thereof is omitted here.

As shown in FIG. 5, the connector portion 52 (rear side engaging portion 39) of the substrate 50 and the connection terminal portion 35 are connected to integrate the two, and the heater portion 20 thereof is opened to the elastic plate 16 and the inner cylinder 70. Insert from the rear end side toward the tip side with respect to 75A. As a result, the stopper portion 30 engages with the front side engaging portion 78 via the elastic plate 16. On the other hand, inside the inner cylinder 70, the compression spring 60 and the cleaning portion 40 are inserted from the front end side to the rear end side. As a result, the internal heating module M is completed by the substrate 50, the connection terminal portion 35, the stopper portion 30, the heater portion 20, the inner cylinder 70 (front side engaging portion 78), the compression spring 60, and the cleaning portion 40.

The elastic ring 18 and the stopper 48 for the cleaning portion are inserted into the holding cylinder 10 in advance from the rear end opening 10B. Then, the internal heating module M is inserted through the rear end opening 10B. When the internal heating module M is pushed toward the tip of the holding cylinder 10, the tip surface of the inner cylinder 70 becomes a step portion 12 for restricting the engaging portion of the holding cylinder 10 via the elastic ring 18 and the stopper 48 for the cleaning portion. Engage in the axial direction. After that, if the rear end cap 80 is screwed into the rear end opening 10B of the holding cylinder 10 and the substrate regulating step portion 88 is brought into contact with the rear end edge of the substrate 50, the inside of the holding cylinder 10 is inside. The heating module M is completely positioned, and the assembly of the smoking tool 1 is completed. As a result, the heater portion 20 is fixed in the axial direction by the heater holding structure 15 (front side engaging portion 78, stopper portion 30, rear side engaging portion 39 (connector portion 52), etc.) provided inside the holding cylinder 10. Will be done. At the same time, since disassembly is easy, only the heater portion 20 (and its integrated parts), which is the most fragile part, can be replaced as a consumable item.

<How to use smoking equipment>

As shown in FIG. 6A, the cigarette T is inserted inward through the tip opening 10A of the holding cylinder 10. As shown in FIG. 6B, when the tobacco T is strongly pushed into the inside, the heating region 22 of the heater portion 20 pierces the inside of the leaf of the tobacco T. At this time, the cleaning portion 40 is temporarily pushed toward the rear end side by the tip of the cigarette T, and the compression spring 60 contracts. However, when the smoker releases his hand from the cigarette T, FIG. 6 (C) shows. As shown, the restoring force of the compression spring 60 slightly pushes back the cleaning unit 40 and the cigarette T to stop. In this state, when the switch 55 is turned on and the heating of the tobacco T by the heater unit 20 is started, the components such as nicotine contained in the leaves of the tobacco T are vaporized, and smoking becomes possible. When smoking is completed, the switch 55 may be turned off (may be automatically turned off by a timer), and then the cigarette T may be pulled out in the axial direction by hand as shown in FIG. 6 (D). At this time, a part of the leaf of the cigarette T may become a residue Z and remain on the peripheral surface of the heater portion 20 or the inner peripheral surface of the inner cylinder 70.

Therefore, after smoking, as shown in FIG. 7A, the smoker vibrates the holding cylinder 10 in the vertical direction while pointing the tip opening 10A of the holding cylinder 10 vertically downward (not shown here). However, when the state shown in FIG. 7A is reached, the cleaning unit 40 moves vertically downward). As a result, as shown in FIGS. 7B and 7C, the internal cleaning unit 40 reciprocates relative to the heater unit 20 and the inner cylinder 70 in the axial direction, thereby scratching the residue Z. Drop it. With this simple operation, the inside of the holding cylinder 10 is always in a clean state. When the state of FIG. 7A is used as a reference, the movement stroke S of the front end surface of the cleaning portion 40 is the stroke SA in the contraction direction (rear end direction) of the compression spring 60 (see FIG. 7B). , Is the sum of the stroke SBs in the tip direction (see FIG. 7C). In this way, by securing a bidirectional stroke at the start of vibration, the initial movement of the cleaning unit 40 can be smoothed.

Further, in the present embodiment, as shown in FIG. 7, the entire cleaning unit 40 is always housed inside the holding cylinder 10 in the entire reciprocating movement process of the cleaning unit 40. By doing so, the cleaning unit 40 whose temperature has risen does not protrude to the outside from the holding cylinder 10, so that the smoker is highly safe.

Further, in the present embodiment, when the heater unit 20 is viewed sideways, at least a part of the cleaning unit 40 overlaps with the heater unit 20 in the entire reciprocating movement stroke of the cleaning unit 40. That is, the heater unit 20 is always present in the through hole 44 of the cleaning unit 40. By doing so, since the heater unit 20 is always held by the cleaning unit 40 during vibration, the trouble of bending the heater unit 20 can be reduced. In particular, in the present embodiment, as shown in FIG. 7C, since the tip of the heater section 20 always protrudes from the cleaning section 40, interference between the tip and the cleaning section 40 is avoided, and at the time of vibration. Damage to the heater unit 20 in the above can be reduced.

As described above, according to the smoking tool 1 of the present embodiment, the heater portion 20 is provided with a stopper portion 30 having a step in the radial direction, and the stopper portion 30 is fixed to the holding cylinder 10 side. By engaging with the joint portion 78 in the axial direction, it is positioned on the tip side in the axial direction. As a result, the positioning accuracy of the heater unit 20 is improved, so that the cigarette can be heated in a stable state at all times.

Further, according to this structure, since the heater portion 20 is positioned not by adhesion or welding but by engagement in the axial direction, the heater portion 20 and the stopper portion 30 are either pulled out from the rear end side or engaged on the front side. By removing the joint portion 78 from the holding cylinder 10, the heater portion 20 can be easily disassembled. In particular, in the present smoking tool 1, the front side engaging portion 78 (inner cylinder 70) is detachable in the axial direction with respect to the holding cylinder 10. Therefore, as shown in FIG. 5, since the front side engaging portion 78 and the heater portion 20 (stopper portion 30) can be assembled and modularized in advance and then mounted on the holding cylinder 10, assembly and disassembly become extremely easy. .. Further, since this structure is easy to disassemble, only the heater portion 20 (and its integrated parts), which is the most fragile part, can be replaced as a consumable item.

At this time, since the holding cylinder 10 side is provided with an engaging portion regulating step portion 12 that regulates the movement of the front side engaging portion 78 (inner cylinder 70) to the tip side in the axial direction. The positioning work of the front side engaging portion 78 (inner cylinder 70) is also facilitated, and as a result, the positioning work of the heater portion 20 is indirectly simplified. Since the positioning accuracy of the front side engaging portion 78 (inner cylinder 70) is also high, the positioning accuracy of the heater portion 20 is also indirectly high.

In the present embodiment, the front side engaging portion 78 is provided by the bottom portion 75 of the inner cylinder 70. Therefore, if the inner cylinder 70 is positioned on the holding cylinder 10, the front side engaging portion 78 can be fixed. Is completed at the same time. Further, due to the heat insulating property of the inner cylinder 70, it is possible to suppress the heat of the heater portion 20 from being transferred to the holding cylinder 10 and the substrate 50 side.

Further, in the present smoking tool 1, a substrate restricting step portion 88 (rear end cap 80) for restricting the movement of the substrate 50 to the rear end side in the axial direction is provided in the holding cylinder 10. When the substrate 50 is positioned toward the rear end side by the substrate regulation step portion 88, the heater portion 20 mounted on the connector portion 52 is also indirectly positioned. Therefore, the heater portion 20 is positioned by the engaging portion 78 with respect to the front end side, and is positioned by the substrate 50 with respect to the rear end side, so that the heater portion 20 is stably held in the holding cylinder 10 in the axial direction.

Further, since the substrate regulating step portion 88 (rear end cap 80) is detachable from the remaining portion of the holding cylinder 10, if this is removed, the substrate 50 and the heater portion 20 can be opened at the rear end of the holding cylinder 10. It can be disassembled very easily from 10B.

Furthermore, since the smoking tool 1 is provided with a cleaning unit 40 that reciprocates in the axial direction with respect to the inner peripheral surfaces of the heater unit 20 and the inner cylinder 70, the residue Z adhering to the heater unit 20 and the like is provided. Can be easily scraped off. As a result, the cigarette storage space 10C can be always kept clean.

In particular, the cleaning unit 40 has a weight region 42 having a predetermined weight, and the cleaning unit 40 is reciprocated in the axial direction due to the inertia when the holding cylinder 10 is vibrated in the axial direction. At this time, since the entire cleaning unit 40 is housed inside the holding cylinder 10 in the entire area of the reciprocating movement process, the safety at the time of cleaning is enhanced. Further, since a slide structure or the like for forcibly operating the cleaning unit 40 from the outside is not required, the structure of the smoking tool 1 can be simplified.

In the smoking tool 1, at least a part of the cleaning unit 40 always overlaps with the heater unit 20 in the axial direction in the entire area of the reciprocating movement stroke. By doing so, since the heater unit 20 is always held by the cleaning unit 40, it is possible to prevent the heater unit 20 from bending. In this embodiment, since the tip of the heater section 20 protrudes from the cleaning section 40, it is possible to suppress the wear of the tip during vibration.

Further, the smoking tool 1 has a compression spring 60 (a urging means) for urging the cleaning portion 40 toward the tip end side. The compression spring 60 can provide the cleaning unit 40 with a stroke SA in the compression direction of the compression spring 60. For example, if the gap between the cleaning unit 40 and the heater unit 20 is clogged with the residue Z of cigarettes, the cleaning unit 40 is pressed to the back side (rear end side) with a stick or the like to compress the compression spring 60. It is possible to release the residue Z clogged in the gap by causing the compression spring 60 to be released or releasing the pressing force to restore the compression spring 60.

<Modification example of heater holding structure>

In the smoking tool 1 of the first embodiment, the case where the connector portion 52 is also used as the rear side engaging portion 39 of the heater holding structure 15 has been exemplified, but the present invention is not limited thereto. For example, as shown in FIG. 8, a concave groove extending in the circumferential direction may be formed around the stopper portion 30, and the opening 75A of the bottom portion 75 may be fitted into the concave groove. By doing so, in the concave groove of the stopper portion 30, the front end side engaging surface 30A that engages with the bottom portion 75 on the front end side and the rear end side engaging surface that engages with the bottom portion 75 on the rear side. A heater holding structure 15 in which 30B is formed and fixed in the axial direction is realized. Incidentally, the bottom portion 75 results in serving both the front side engaging portion 78 and the rear side engaging portion 39.

At this time, as shown in FIGS. 8B to 8D, it is preferable that the inner cylinder 70 is configured to be separable into a plurality of cylinder pieces 71 by the separation boundary 70X extending in the axial direction. In this way, if the inner cylinder 70 (front side engaging portion 78 and rear side engaging portion 39) including the opening 75A can be disassembled in the radial direction, these can be freely fitted into the recesses of the stopper 30. It can be combined or separated. Here, the case of separating into two cylinder pieces 71 is illustrated, but it may be separated into three or more.

Further, in the modified example of FIG. 8, a case where a concave groove extending in the circumferential direction is provided around the stopper portion 30 and fitted with the opening 75A of the bottom portion 75 is illustrated, but the present invention is not limited to this. For example, as in the heater holding structure 15 shown in FIG. 9, the stopper portion 30 of the heater portion 20 is omitted, and the heater portion 20 is pressed so as to be sandwiched from the radial direction by the opening 75A of the bottom portion 75, and the holding force (friction) thereof is obtained. The heater portion 20 may be fixed and held in the axial direction by force). At this time, it is preferable to effectively suppress the relative slip in the axial direction by arranging the high friction resistance material 75B such as high heat resistant rubber on the inner circumference of the opening 75A (or the outer circumference of the heater portion 20).

Further, in the smoking tool 1 of the first embodiment, the case where the bottom portion 75 of the inner cylinder 70 is engaged with the stopper portion 30 of the heater portion 20 is exemplified as the heater holding structure 15, but the present invention is not limited thereto. For example, as shown in FIG. 10, the inner cylinder 70 may be omitted, and a circular holding plate 76 instead of the bottom portion 75 may be fixed to the inner circumference of the holding cylinder 10. An opening 76A is formed in the holding plate 76, and the heater portion 20 is inserted into the opening 76A. A stepped portion (here, a concave groove extending in the circumferential direction) 10P is formed on the inner peripheral surface of the holding cylinder 10, and the holding plate 76 is engaged with the stepped portion 10P in the axial direction (particularly in the tip direction). Match. As a result, since the holding plate 76 is fixed in the holding cylinder 10 in the axial direction (particularly in the tip direction), the heater portion 20 can be held via the holding plate 76.

At this time, as shown in FIGS. 10B and 10C, it is preferable that the holding cylinder 10 is configured to be separable into a plurality of cylinder pieces 10Y by the separation boundary 10X extending in the axial direction. In this way, if the holding cylinder 10 including the stepped portion (recessed groove) 10P is made disassembled in the radial direction, the holding plate 76 can be freely held or opened by the stepped portion 10P. Here, the case of separating into two cylinder pieces 10Y is illustrated, but it may be separated into three or more. By attaching the female tip cap 77 to the tip side of the holding cylinder 10 and attaching the female rear end cap 80 to the rear end side, the holding cylinder 10 is radially oriented after assembly. Do not separate. Since the holding cylinder 10 has a divided structure, the cleaning section regulating step portion 49 is directly formed on the inner peripheral surface of the holding cylinder 10, and the tip surface of the cleaning portion 40 is engaged with the cleaning section 40 in the axial direction. You may combine them. On the other hand, when the holding cylinder 10 is not a split structure, the cleaning section regulating step portion 49 may be provided on the tip cap 77 side.

Further, in the heater holding structure 15 of FIG. 10, a case where a holding plate 76 as an independent member is interposed between the holding cylinder 10 and the heater portion 20 is illustrated, but the present invention is not limited thereto. For example, as shown in FIG. 11A, the holding plate can be omitted by forming the stopper portion 30 of the heater portion 20 into a plate shape that reaches the inner peripheral surface of the holding cylinder 10. Therefore, the outer peripheral edge of the stopper portion 30 is axially engaged with the step portion 10P formed on the inner peripheral surface of the holding cylinder 10. Due to the concave groove (bidirectional step portion) of the step portion 10P, the heater portion 20 cannot move in both axial directions. That is, the recess 10P also serves as the rear engaging portion 39 and the front engaging portion 78.

Further, as in 11 (B), the step portion 10P may be a unidirectional step portion whose diameter is reduced from the rear end side toward the tip side. By doing so, it is possible to restrict the movement of the heater portion 20 toward the tip end only by inserting the stopper portion 30 of the heater portion 20 from the rear end side of the holding cylinder 10 and engaging it with the step portion 10P. In this case, since it is not necessary to form the holding cylinder 10 in a divided structure, the tip cap 77 can be omitted. Although not particularly shown, a structure in which the stopper portion 30 is inserted from the tip side can also be adopted as a step portion in the other direction in which the step portion 10P is reduced in diameter from the front end side to the rear end side.

Furthermore, as shown in FIG. 12, the holding plate 76 of FIG. 10 may be integrally molded on the inner peripheral surface of the holding cylinder 10. In this case, as shown in FIGS. 12B and 12C, it is preferable that the holding cylinder 10 and the holding plate 76 can be divided in the radial direction, which improves convenience during assembly and disassembly.

In the heater holding structure 15 of the first embodiment, the case where the bottom portion 75 and the elastic plate 16 are flattened and the stopper portion 30 is engaged only in the axial direction is illustrated, but the present invention is not limited thereto. For example, as shown in FIG. 13A, a convex portion 75E may be formed on the rear surface side of the bottom portion 75, and a concave groove 75F extending in the radial direction may be formed in the convex portion 75E. When at least a part of the stopper portion 30 is inserted into the concave groove 75F, the stopper portion 30 is positioned in the radial direction or the circumferential direction, so that the central axis of the heater portion 20 and the central axis of the holding cylinder 10 are coaxial. The accuracy can be improved. Further, as shown in FIG. 13B, it is also preferable that the concave groove 75F has a tapered shape (V-groove shape). By doing so, the frontage on the insertion side of the concave groove 75F becomes wide, so that the stopper portion 30 can be easily inserted, and the stopper portion 30 to be inserted can automatically realize centering along the inclined surface. , The coaxial accuracy can be further improved. Further, if the concave groove 75F has a tapered shape, there is an advantage that the inclination of the stopper portion 30 can be appropriately allowed if an external force acts on the heater portion 20 to incline the groove portion 20.

In addition, in FIG. 13, since the wall thickness of the bottom portion 75 is thin, the convex portion 75E is formed on the rear surface side and the concave groove 75F is formed in the convex portion 75E. , The concave groove 75F may be formed directly on the rear surface side.

Next, the smoking device 1 according to the second embodiment of the present invention will be described with reference to FIG. The parts, members, and structures that are the same as or similar to the smoking equipment of the first embodiment will be omitted, and only the points different from those of the first embodiment will be described.

The cleaning portion 40 has a leg portion 46 extending in the axial direction on the rear end side. The leg portion 46 penetrates the leg portion opening 75B formed in the bottom portion 75 of the inner cylinder 70 and extends toward the substrate accommodating space 10D. On the other hand, the compression spring (urging member) shown in the first embodiment is omitted. As shown in FIG. 14B, the length of the leg portion 46 is set so that a part of the leg portion 46 always extends to the substrate accommodating space 10D within the range of the entire stroke of the cleaning portion 40. Is preferable.

According to the smoking tool 1 according to the second embodiment, when the cleaning portion 40 cannot be reciprocated for some reason, the rear end cap 80 is removed and the leg portion 46 is pushed toward the tip side with a stick or the like. For example, the cleaning unit 40 can be forcibly moved.

Next, the smoking device 1 according to the third embodiment of the present invention will be described with reference to FIG. The parts, members, and structures that are the same as or similar to the smoking equipment of the second embodiment will be omitted, and only the points different from those of the second embodiment will be described.

In this smoking tool 1, the legs 46 of the cleaning portion 40 are set thicker as compared with the second embodiment. By doing so, the weight of the leg portion 46 is increased, so that the leg portion 46 can bear a part or all of the weight region 42. As a result, it is possible to reduce the volume of the cleaning portion 40 on the main body side excluding the leg portion 46, so that the size can be reduced in the axial direction. As a result, the total length of the smoking device 1 in the axial direction is shorter than that of the first and second embodiments.

As a modification of the third embodiment, as shown in FIGS. 16 and 17, a geta portion 47 extending in the radial direction is connected to the vicinity of the rear end of the leg portion 46, and the geta portion 47 is held by the holding cylinder. It is preferable to project outward from 10 and provide an operation unit 120 at the tip thereof. When the user slides the operation unit 120 in the axial direction, the cleaning unit 40 moves in the axial direction via the leg unit 46 in conjunction with this. As a result, the heater portion 20 can be manually cleaned without shaking the holding cylinder 10, so that the weight of the leg portion 46 can be reduced. The holding cylinder 10 is formed with an axial slit 10S for avoiding interference with the sliding clogs 47. Specifically, the operation portion 120 and the clog portion 47 are integrally formed, the clog portion 47 is inserted into the inside through the slit 10S, and the innermost end of the clog portion 47 is formed on the leg portion 46. Insert into opening 46A. As a result, the clogs 47 and the legs 46 are internally connected. At this time, a return protrusion 47A is formed on the side surface of the clog portion 47, and the return protrusion 47A is forcibly pushed into the slit 10S at the time of insertion. After the insertion, the return protrusion 47A becomes an obstacle so that the clog portion 47 cannot be easily removed from the slit 10S. At the time of disassembly, if the clogs 47 are forcibly pulled, the return protrusion 47A and the slit 10S are disengaged and can be removed from the slit 10S. The operation unit 120 is formed with a notch 120A for avoiding interference with the external operation unit 11B, if necessary.

Next, the smoking device 1 according to the fourth embodiment of the present invention will be described with reference to FIG. The parts, members, and structures that are the same as or similar to the smoking equipment of the second embodiment will be omitted, and only the points different from those of the second embodiment will be described.

As compared with the second embodiment, the engaging protrusion 46A is projected from the rear end of the leg portion 46 of the cleaning portion 40. The engaging protrusion 46A can be axially engaged with the leg opening 75B. Therefore, as shown in FIG. 18B, when the cleaning portion 40 moves toward the tip end side, the engaging protrusion 46A and the leg opening 75B engage with each other, and the cleaning portion 40 stops. Along with this, the stopper 48 for the cleaning portion shown in the first embodiment becomes unnecessary, so that the inner cylinder 70 extends integrally to the step portion 12 for restricting the engaging portion. Although the compression spring 65 is provided in FIG. 18, it can be omitted.

Next, the smoking device 1 according to the fifth embodiment of the present invention will be described with reference to FIG. 19 (A). The parts, members, and structures that are the same as or similar to the smoking equipment of the fourth embodiment will be omitted, and only the points different from those of the fourth embodiment will be described.

As compared with the fourth embodiment, an escape space 90 for avoiding contact with the heater portion 20 is formed inside the main body of the cleaning portion 40. The escape space 90 reaches the rear end of the main body of the cleaning unit 40. As a result, the front end surface of the main body of the cleaning unit 40 is in contact with the heater unit 20 and can be cleaned, but the rear end surface is not in contact with the heater unit 20 due to the escape space 90.

The escape space 90 can reduce the sliding resistance when the cleaning unit 40 reciprocates. Further, since the contact area with the heater unit 20 is reduced, it is possible to suppress the heat of the heater unit 20 from being transferred to the substrate 50 side. At the same time, the air warmed in the escape space 90 enters the cigarette side through the through hole 44 at the time of suction, so that the suction efficiency can be improved. In order to effectively heat the air in the escape space 90, it is desirable to extend the heating region 22 of the heater unit 20 to the inside of the escape space 90.

In the smoking tool 1, the leg portion 46 is linearly guided by the leg opening 75B, so that the posture of the cleaning portion 40 is always stable. Along with this, as shown in FIG. 19B, the outer edge of the tip surface of the cleaning portion 40 can be separated from the inner wall of the inner cylinder 70. That is, an annular second escape space 92 is also formed around the tip surface of the cleaning portion 40. In this way, the heat of the tip surface of the cleaning portion 40 is difficult to transfer to the inner cylinder 70. The residue Z of cigarettes may enter the second escape space 92, but if the outer peripheral edge of the cleaning portion 40 is brought close to the inner cylinder 70 on the base end side of the main body, cleaning is performed. It will be possible.

Next, the smoking device 1 according to the sixth embodiment of the present invention will be described with reference to FIG. 20 (A). The parts, members, and structures that are the same as or similar to the smoking equipment of the first embodiment will be omitted, and only the points different from those of the first embodiment will be described.

The smoking tool 1 has a structure without a cleaning portion. Therefore, the bottom portion 75 of the inner cylinder 70 is thickened in the axial direction so as to supplement the space of the cleaning portion. In this way, if the bottom portion 75 is made thick and the heater portion 20 is held by the opening 75A, the posture of the heater portion 20 can always be stabilized. The bottom portion 75 is not limited to the case where it is integrated with the inner cylinder 70, and may be a separate body.

It is preferable that the opening 75A formed in the bottom portion 75 holds at least a part of the heating region 22 on the tip side of the heater portion 20. That is, it is preferable that the tip surface of the bottom portion 75 reaches the heating region 22. By doing so, the axial distance (hereinafter referred to as the holding distance) from the connection terminal portion 35 or the stopper portion 30 to the holding portion of the heater portion 20 by the opening 75A becomes long, so that the posture of the heater portion 20 becomes stable. As a result, it is possible to increase the durability against the bending moment acting on the heater portion 20 when the cigarette is inserted. Further, the tip of the inserted tobacco can be sufficiently heated by the heating region 22, so that the tobacco leaves are not wasted.

In order to stabilize the posture of the heater unit 20, it is preferable to secure a certain degree of axial length of the non-heating region 24. On the other hand, it is also possible to shorten the axial length of the non-heating region 24 to shorten the holding distance, and the heater portion 20 tends to be slanted with respect to the axis of the holding cylinder 10. , Bending moment can be absorbed moderately.

Further, as a modification of the smoking tool 1 according to the sixth embodiment, it is preferable to form an escape space 90 in the bottom portion 75 as shown in FIG. 20 (B). The escape space 90 reduces the contact area between the bottom portion 75 and the heater portion 20. As a result, it is possible to suppress a situation in which the heat of the heater portion 20 is wastedly released through the bottom portion 75.

It is preferable that the escape space 90 reaches the substrate 50 side. That is, the front end surface of the bottom portion 75 holds the heater portion 20, but the rear end surface is not brought into contact with the heater portion 20 by the escape space 90. On the other hand, in order to make the bottom portion 75 function as the front side engaging portion 78, a part of the bottom portion 75 may be engaged only with the stopper portion 30.

The air warmed in the escape space 90 may be allowed to enter the cigarette side through the opening 75A at the time of suction to improve the suction efficiency. In order to effectively heat the air in the escape space 90, it is desirable to extend the heating region 22 of the heater unit 20 to the inside of the escape space 90.

The shape of the bottom portion 75 and the front side engaging portion 78 is not limited to the case shown in FIG. 20, and can be variously deformed. For example, as in the modified example shown in FIG. 21, the bottom portion 75 holding the heater portion 20 may be thinned, and the position fixing leg portion 93 may extend from the bottom portion 75 toward the rear end side. If the position fixing leg portion 93 is brought into contact with the substrate restricting step portion 88, positioning of the rear end side of the bottom portion 75 is realized.

At this time, as shown in FIG. 21B, the clip means 94 may be provided on the connector portion 52 of the substrate 50. The clip means 94 functions as the front side engaging portion 78 of the present invention and engages with the stopper portion 30 in the axial direction. As a result, it is possible to prevent the heater portion 20 from falling off to the tip side. If the clip means 94 is opened, the connection terminal portion 35 can be pulled out as shown in FIG. 21 (C).

Next, the smoking device 1 according to the seventh embodiment of the present invention will be described with reference to FIG. 22. The parts, members, and structures that are the same as or similar to the smoking equipment of the first embodiment will be omitted, and only the points different from those of the first embodiment will be described.

In the smoking tool 1, the holding cylinder 10 includes a removable tip cap 77 in the vicinity of the tip. Here, a male screw is formed on the outer peripheral surface near the tip of the holding cylinder 10 excluding the tip cap 77, and a female screw is formed on the inner peripheral surface of the tip cap 77. By screwing a male screw and a female screw, both are connected. The tip cap 77 has an annular shape, and a tip opening 10A and a step portion 12 for restricting an engaging portion are formed. When the tip cap 77 is removed, the engaging portion regulating step portion 12 is indirectly separated from the remaining portion of the holding cylinder 10.

When assembling the smoking tool 1, the tip cap 77 should be removed in advance, and at least the front engaging portion 78 and the heater portion 20 should be inserted axially from the tip side to the rear end side of the holding cylinder 10. Just do it. Specifically, the internal heating module M is pre-assembled using the substrate 50, the connection terminal portion 35, the stopper portion 30, the heater portion 20, the inner cylinder 70 (front side engaging portion 78), the compression spring 60, and the cleaning portion 40. Then, the internal heating module M is inserted from the tip end side of the holding cylinder 10.
