Description

Smoking equipment

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

Conventionally, smoking ignites the leaves of cigarettes, vaporizes components such as nicotine and tar contained in the leaves of cigarettes at the time of burning (air-dispersed particles or fumes), and sucks 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.

The smoking tool referred to in Patent Document 1 has a heater for heating 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. It has become. When the leaves of cigarettes are heated by this heater, nicotine and the like are vaporized and can be sucked.

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. In the following description, the virtual axis along the insertion direction of the cigarette is defined as the insertion axis C, the smoker side in the insertion direction in the smoking posture is defined as the front side, and the opposite side is defined as the back side. The smoking tool 1 is arranged inside a cylindrical cylinder portion 73 into which a cigarette is inserted from the front side to the back side, and inside the cylinder portion 73, and extends in the axial direction of the cylinder portion 73 to heat the cigarette. The heater unit 20, the stopper unit 30 integrally provided on the base end side (back side) of the heater unit 20, and the connection for the heater unit 20 integrally provided on the base end side of the heater unit 20 to receive power. The terminal portion (heat receiving portion on the heater side) 35, the heater support 70 arranged on the inner side of the cylinder portion 73 and engaging with the stopper portion 30, and the heater portion 20 are arranged so as to be reciprocally movable in the axial direction. It has a cleaning unit 40, a substrate 50 and the like arranged in parallel with the cylinder unit 73.

The cylinder portion 73, the heater portion 20, the heater support 70, the substrate 50, and the like are housed in the housing 10. The housing 10 is divided into a front side housing 10A and a back side housing 10B, and can be separated along the insertion axis C direction.

<Cylinder>
As shown in FIG. 2A, the tubular portion 73 has a substantially cylindrical shape here, and has a front side opening 73A and a back side opening 73B. The inside of the cylinder portion 73 is a cigarette storage space 73C in which a part of the cigarette is housed. The cylinder portion 73 is made of metal (aluminum in this embodiment), and is made of a material (independent member) different from the material (resin in this embodiment) of the surrounding outer cylinder 13. By making the tubular portion 73 an independent component with respect to the front housing 10A, it is possible to form a structure in which the heat of the tubular portion 73 is not easily transferred to the front housing 10A. The wall thickness of the peripheral wall of the tubular portion 73 is preferably 0.2 mm or more, more preferably 0.4 mm or more, and even more preferably 0.6 mm or more. The inner diameter of the tubular portion 73 is preferably in the range of 6.0 mm to 9.0 mm, more preferably 7.0 mm to 7.8 mm. The inside of the tubular portion 73 serves as a holding space 73C for holding the cigarette. As shown in FIG. 3B, the maximum accommodation length G of the cigarette in the holding space 73C of the tubular portion 73 is preferably 10 mm to 20 mm, more preferably 11 mm or more and 18 mm or less, and further preferably 12 mm or more and 16 mm or less. And. If the stopper step portion 12A (details will be described later) is provided on the inner side, the maximum accommodation length G of the tubular portion 73 can be further reduced. The distance E from the innermost surface (bottom surface) of the holding space 73C to the opening K of the front side housing 10A is preferably 12 mm to 45 mm, more preferably 15 mm or more and 40 mm or less. When the wall thickness of the cylinder portion 73 is increased, the amount of heat stored in the cylinder portion 73 increases, so that the fluctuation range of the temperature due to aeration during smoking (during suction) can be reduced. Since the rigidity of the tubular portion 73 is also increased, deformation during disassembly and cleaning can be suppressed. On the other hand, by shortening the maximum accommodation length G of the tobacco in the cylinder portion 73 to about the length of the leaf portion of the tobacco, only the leaf portion of the tobacco can be heated in a limited manner, and power saving can be achieved. The cylinder portion 73 can be made of a material other than metal, and for example, a highly heat-resistant resin can be used. Further, the shape of the cylinder portion 73 is not limited to a complete cylinder shape in which both ends are open, and may be a bottomed cylinder shape in which the bottom portion is formed on one side (the tip end side of the cigarette).

As shown in FIG. 2B, the cylinder portion 73 is inserted inside the outer cylinder 13 formed in the front side housing 10A. As shown in FIG. 3, the outer cylinder 13 is formed with a stopper step portion 12A whose inner wall diameter is reduced inward in the radial direction. The stopper step portion 12A engages with the front opening 73A of the cylinder portion 73. The tubular portion 73 cannot move toward the front side in the insertion axis C direction. On the other hand, the inner opening 73B of the tubular portion 73 is in contact with the heater support 70 described later, so that the tubular portion 73 cannot move to the inner side in the insertion shaft C direction. As a result, the tubular portion 73 is held so as to be sandwiched between the stopper step portion 12A and the heater support 70. It is preferable to form a gap 13X in the circumferential direction between the cylinder portion 73 and the outer cylinder 13, so that the heat of the cylinder portion 73 is not easily transferred to the outer cylinder 13.

<Case>
The housing 10 has a cigarette heating space 10E and a substrate accommodating space 10D. As shown in FIG. 3A, the cigarette heating space 10E and the substrate accommodating space 10D are arranged in parallel in the orthogonal direction of the insertion axis C. As shown in FIG. 2B, the cigarette heating space 10E is mainly composed of the front housing 10A. An opening K for inserting a cigarette is formed on the front surface of the front housing 10A. As shown in FIG. 2A, the substrate accommodating space 10D is mainly composed of the rear housing 10B. The back side of the cigarette heating space 10E is covered with the back side housing 10B. The front side of the substrate accommodating space 10D is mainly covered by the front side housing 10A.

The front side housing 10A includes a board cap area 80 that covers the front side of the board accommodation space 10D. As shown in FIG. 3C, the inner side surface (back side surface) of the substrate cap region 80 is the substrate regulation end surface 80A. The substrate restricting end surface 80A abuts on the front side edge of the substrate 50 to restrict the movement of the substrate 50 in the insertion axis C direction. On the other hand, if the front side housing 10A is removed from the back side housing 10B, the substrate 50 can be taken out from the board accommodation space 10D of the back side housing 10B.

The back side housing 10B includes a heating space cap region 88 that covers the back side of the cigarette heating space 10E. As shown in FIG. 3A, a stepped portion 88A that engages with the heater support 70 from the back side is formed inside the heating space cap region 88. The step 88A restricts the movement of the heater support 70 to the back side. On the other hand, since the heater support 70 is engaged with the back opening 73B of the cylinder 73, the movement of the front side is restricted by the cylinder 73. If the back housing 10B is removed from the front housing 10A, the heater support 70, the heater portion 20, the cylinder portion 73, and the like can be taken out from the cigarette heating space 10E of the front housing 10A. The front housing 10A and the back housing 10B are connected by a claw, press fitting, or the like.

As shown in FIG. 2A, a pair of slit-shaped substrate recesses 14 extending in the insertion axis C direction are formed on the inner wall of the substrate accommodation space 10D in the rear housing 10B. The substrate 50 is positioned in the substrate accommodating space 10D by inserting both end edges of the rectangular substrate 50 in the width direction into the pair of substrate recesses 14. The longitudinal direction (insertion axis C direction) of the substrate 50 is positioned by being sandwiched between the back side housing 10B and the front side housing 10A in the insertion axis C direction. As a result, the plane direction (longitudinal direction) of the substrate 50 is parallel to the insertion axis C direction.

As shown in FIG. 3A, when viewed from the orthogonal direction of the insertion axis C, the range of 50% or more in the insertion axis direction of the substrate 50 and the range of 50% or more in the insertion axis direction of the tubular portion 73 are mutual. It becomes a positional relationship superimposed on. As a result, as shown in FIG. 1 (D), the outer dimension L (excluding the first power receiving connector 54A protruding outward as a male) of the housing 10 in the insertion axis C direction can be compactly configured. .. Here, the outer dimension L is 8 cm or less, preferably 6 cm or less, and more preferably 5 cm or less. In this embodiment, it is set to about 3.6 cm, which is 4 cm or less.

Further, as shown in FIGS. 3B and 3C, the total width of the substrate 50 in the orthogonal direction (width direction) of the insertion axis C of the substrate 50 is 50% or more when viewed from the orthogonal direction of the insertion axis C. The positional relationship is such that it overlaps with 80% or more of the insertion axis C orthogonal direction (diameter direction) of 73. In particular, 50% or more of the total width in the insertion axis C orthogonal direction (width direction) of the substrate 50 overlaps with the total width in the insertion axis C orthogonal direction (diameter direction) of the tubular portion 73. As a result, the substrate 50 and the tubular portion 73 are compactly configured so as to overlap each other. Therefore, as shown in FIG. 1C, the outer dimension W2 in the direction orthogonal to the insertion axis C of the housing 10 can be compactly configured. can. Here, the outer dimension W2 is 4 cm or less, preferably 3 cm or less (actually 2.3 cm). In the present embodiment, the outer dimension W1 of the housing 10 is also compactly configured to be 4 cm or less, preferably 3 cm or less (actually 2.5 cm).

<Heater part, etc.>
As shown in FIG. 3B, the heater portion 20 has a rod shape 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 (not shown) that becomes hot when energized due to a high resistance value, inside or on the surface. In the non-heated region 24, a low temperature wiring element (not shown) having a lower resistance value than the high temperature wiring element and hardly generating heat even during energization is provided inside or on the surface. The tip of the heater portion 20 has a conical shape whose diameter is reduced toward the tip so that 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 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 stopper portion 30 is housed in a key-shaped recess 78 formed in the heater support 70 and engages with each other in the insertion shaft C direction (see FIG. 3A).

Further, a connection terminal portion (heat receiving portion on the heater side) 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 insertion axis C direction. As shown in FIGS. 2A and 3A, the connection terminal portion 35 is electrically connected to the substrate side terminal portion (board side supply portion) 52 of the substrate 50 by the wiring 63. The metal pin may be long, for example, 3 cm or more, and may also serve as the wiring 63 by covering it with an insulating tube. By the way, by arranging the connection terminal portion 35 on the back side and the board side terminal portion 52 on the front side in the housing 10, the length of the wiring 63 is positively lengthened, and at the same time, the wiring 63 is formed on the outer cylinder. The outer peripheral side of 13 is crawled. By lengthening the wiring 63, it is possible to suppress the heat of the heater unit 20 from being transferred to the substrate 50 via the wiring 63. The length of the wiring 63 is preferably 1 cm or more, more preferably 3 cm or more, and further preferably 4 cm or more from the viewpoint of heat insulating properties. The connection terminal portion 35 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. Further, the connection terminal portion (heat receiving portion on the heater side) 35 and the wiring 63 may be integrated.

<Board>
As shown in FIG. 2, the substrate 50 is connected to the substrate side terminal portion (board side supply portion) 52, which is arranged near the edge on the front side and where the wiring 63 is welded, the power control circuit 53, and the outside. It includes first and second

power receiving connectors

54A and 54B to which electric power is supplied, an input switch 55, an LED 56, and a temperature control volume 57. A slit 50A is formed in the vicinity of the substrate-side terminal portion 52 of the substrate 50 so that the heat of the heater portion 20 transmitted via the wiring 63 does not diffuse to the entire substrate 50 (FIG. FIG. 3 (C)). The first power receiving connector 54A is a large-sized USB standard connector (male / type A) and is connected to an external power source. The second power receiving connector 54B is a small miniUSB standard or MicroUSB standard (here, MicroUSB standard) connector (female / type B) and is connected to an external power supply. The housing 10 (back side housing 10B) is formed with a first connector opening 11A for exposing (protruding) the male shape of the first power receiving connector 54A to the outside. Similarly, the housing 10 (back side housing 10B) is formed with a second connector opening 11B for allowing the female shape of the second power receiving connector 54B to face the outside (see FIG. 1B). By preparing both large and small USB standards as the first and second

power receiving connectors

54A and 54B, it is possible to support various external power supplies. The connector may be other than the USB standard, for example, Apple Inc. The company's Lightning® standard may be adopted.

As shown in FIG. 1, the first power receiving connector 54A having a male shape is arranged so as to project toward the inner side in the insertion axis C direction on the inner side surface of the housing 10. As a result, the connection direction of the first power receiving connector 54A (the direction of attachment / detachment to / from the external power source) is parallel to the direction of the insertion shaft C. On the other hand, the female-shaped second power receiving connector 54B faces the side surface of the housing 10 (the surface orthogonal to the front side surface and the back side surface). As shown in FIG. 1 (E), when the back side direction of the insertion shaft C is 0 degree, the connection direction (attachment / detachment direction to / from the external power supply) R of the second power receiving connector 54B is the insertion shaft C direction (the first). It has an angle α with respect to (1 connection direction of the power receiving connector 54A), and here the angle α is set to 20 degrees or more and 120 degrees or less, and is 90 degrees in this embodiment.

Further, as shown in FIG. 1 (E), when viewed from the side surface, the second power receiving connector 54B overlaps with the cigarette holding space 73C in the tubular portion 73. More specifically, the center position R in the insertion shaft C direction of the second power receiving connector 54B is located on the front side of the center Lm of the outer dimension L in the insertion shaft C direction of the housing 10. Although the details will be described later, when the second power receiving connector 54B is set to such a position, the smoking cigarette is hard to break when an external force acts on the second power receiving connector 54B. Is possible.

Further, as shown in FIG. 2A, the width direction Wa of the first power receiving connector 54A is parallel to the surface direction of the substrate 50. The width direction Wb of the second power receiving connector 54B is also parallel to the surface direction of the substrate 50. As a result, even when the first power receiving connector 54A and the second power receiving connector 54B are directly mounted on the substrate 50, the whole can be configured extremely thin.

The first and second

power receiving connectors

54A and 54B are connected to a battery or battery as an external power source, or are connected to a converter (AC-DC adapter) that converts a household AC power source (commercial power source) into a direct current. The external power supply connected to the first and second

power receiving connectors

54A and 54B is preferably a DC power supply of about 5.0 V. The smoking tool 1 of the present embodiment is characterized in that a battery or a battery is not mounted inside, but a battery may be built in as a preliminary. The power control circuit 53 controls the current and / or voltage supplied via the first and second

power receiving connectors

54A and 54B to adjust the temperature of the heating region 22 of the heater unit 20. For example, in the reference power mode (described later), it is preferable to control the power so that it is stable at an average voltage of 5.0 V and an average current of 0.4 to 1.0 A (more than 0.6 A in this embodiment). Further, in the high power mode (described later), it is preferable to control so as to be stable at an average voltage of 5.0 V and an average current of more than 1.0 A (more than 1.5 A in this embodiment). Although it depends on the temperature and humidity of the external environment, for example, it is preferable to control the heating region 22 within the range of 180 ° C. (reference power mode side) to 240 ° C. (high power mode side) according to the purpose.

The input switch 55 is a button switch for switching the heating ON / OFF and the heating mode by the heater unit 20. This operation is performed on the side surface of the housing 10 via the external operation unit 11C which is movably arranged in the direction orthogonal to the insertion axis C (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 11D formed in the housing 10 (see FIGS. 1A and 1F).

The temperature adjustment volume 57 is a volume switch that adjusts the temperature level of heating by the heater unit 20. This operation is performed by exposing a part of the rotatable disk 57A from the side surface of the housing 10 and rotating the disk 57A. The present invention is not limited to the rotary volume, and an electronic volume provided with a setting button, a set value digital display screen, a non-volatile storage device for holding the final setting state, and the like can also be adopted.

<Heater support, etc.>
As shown in FIG. 3A, the heater support 70 is a cylindrical member having a heater through hole 75A through which the heater portion 20 penetrates. The heater portion 20 is inserted into the heater through hole 75A from the rear end side toward the front end side. It is preferable to have a gap between the heater through hole 75A and the heater portion 20. The gap can prevent the heat of the heater portion 20 from being transferred to the heater support 70. Further, at the time of suction, since the outside air is introduced into the heater unit 20 and the surrounding cigarettes through this gap, the heat of the heater unit 20 can be diffused to the entire cigarette. The heater support 70 is preferably made of a material having high heat insulating properties and / or heat resistance (for example, a material having high heat resistance such as polycarbonate, polypropylene, PEEK, etc.). This is because the heat of the heater unit 20 can be suppressed from being transferred to the housing 10. A key-shaped recess 78 is formed in the middle of the heater through hole 75A, and engages with the stopper portion 30 of the heater portion 20 in the insertion shaft C direction. As a result, the heater support 70 can hold the heater portion 20. On the other hand, as shown in FIGS. 3B and 4A, an engaging protrusion 79 is formed on the outer peripheral surface of the heater support 70 and engages with the rear housing 10B (not shown). It plays the role of a rotation stopper. The heater support 70 and the tubular portion 73 may be integrated (integrated into a single member).

<Cleaning section>
As shown in FIG. 4, the cleaning unit 40 is arranged so as to be reciprocating in the axial direction while approaching or abutting on the outer peripheral surface of the heater unit 20. As shown in FIG. 4A, the cleaning portion 40 is a cylindrical member, and a through hole 44 is formed inside the cleaning portion 40. 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 tubular portion 73 (that is, the inner peripheral surface of the cigarette holding space 73C). As a result, the cleaning portion 40 approaches or comes into contact with the inner peripheral surface of the tubular portion 73, and can reciprocate from the rear end surface 73B toward the front side while sliding in the axial direction.

As shown in FIG. 4B, a saw-toothed first protrusion 40A having a saw-tooth cross section is formed on the tip surface of the cleaning portion 40 along the edge of the through hole 44. The first protrusion 40A has a role of scraping off tobacco leaves adhering to the outer peripheral surface of the heater portion 20, and also suppresses the burning of tobacco accumulated on the tip surface of the cleaning portion 40 from entering the through hole 44. Take on the role of Further, on the tip surface, a second protrusion 40B having a saw-tooth cross section is formed so as to be convex toward the front along the outer peripheral edge. The second protrusion 40B plays a role of preventing scorching and the like from entering the gap between the cylinder portion 73 and the cleaning portion 40, and scraping off tobacco leaves and rolling paper adhering to the inner peripheral surface of the cylinder portion 73. ..

The back side of the cleaning portion 40 has a leg portion 46 extending in the insertion shaft C direction. The leg portion 46 penetrates the leg portion opening 75B formed in the heater support 70 and extends to the back side. In the present embodiment, the leg opening 75B is continuous with the heater through hole 75A, but may be formed separately.

As shown in FIG. 4A, a clog portion 47 extending in the direction orthogonal to the insertion axis C is engaged in the vicinity of the rear end of the leg portion 46. An operation unit 120 is integrally provided on the clogs 47, and the operation unit 120 is projected (exposed) outward from the housing 10 (see FIG. 1 (B)). When the user slides the operation unit 120 from the back side in the axial direction to the front side, the leg portion 46 and the cleaning portion 40 are interlocked with the front side in the axial direction so as to be pushed by the clogs 47. As a result, the heater unit 20 and the cleaning unit 40 can be slid relative to each other so that the cigarette can be easily taken out and at the same time the heater unit 20 can be cleaned. On the other hand, the movement of the leg portion 46 and the cleaning portion 40 to the inner side in the axial direction is performed by pushing the cleaning portion 40 with a cigarette or the like. As shown in FIG. 3B, a step portion 46A is formed at the rear end of the leg portion 46. By engaging the step portion 46A with the back end surface 73B of the tubular portion 73, slipping out of the cleaning portion 40 is restricted. It is also preferable to engage the clogs 47 and the legs 46 in both directions of the insertion shaft C, and the legs 46 and the cleaning portion 40 can be moved to the back side by the operation portion 120.

As shown in FIGS. 1 (G) and 2 (B), the front side housing 10A and / or the back side housing 10B has a shaft for avoiding interference with the sliding clogs 47 and the operation unit 120. A directional slit 10S is formed. Further, as shown in FIG. 3B, a guide groove 10T for guiding the operation unit 120 in the insertion shaft C direction is formed inside the front side housing 10A and / or the back side housing 10B. When the operation unit 120 is housed in the guide groove 10T, the clogs portion 47 is in a posture of engaging with the inner end of the leg portion 46.

<Insulation structure>
As shown in FIG. 5A, the isolation wall 60 is detachably arranged in the rear housing 10B at a location adjacent to the cylinder portion 73 and the outer cylinder 13. The isolation wall 60 partitions the tobacco heating space 10E and the substrate accommodating space 10D, and suppresses the transfer of heat on the tobacco heating space 10E side to the substrate accommodating space 10D. The isolation wall 60 is a plate-shaped member that extends in the insertion axis C direction. As shown in FIG. 3A, a fine first gap 62A is formed between the isolation wall 60 and the outer cylinder 13, and the air in the first gap 62A plays the role of a heat insulating material. It has become like. A second gap 62B is formed between the isolation wall 60 and the substrate 50, and the air in the second gap 62B plays the role of a heat insulating material and suppresses heat transfer to the substrate 50.

In the first gap 62A, a first heat reflecting layer / heat guiding layer 64A made of a material having a high heat reflectance such as copper or an aluminum sheet is arranged. In the second gap 62B, a second heat reflecting layer / heat guiding layer 64B made of a material having a high heat reflectance such as copper or an aluminum sheet is arranged. The first and second heat-reflecting layers / heat-conducting

layers

64A and 64B are made of a material having heat-reflecting characteristics and / or heat-conducting characteristics, and suppress the heat transfer on the heater portion 20 side to the substrate accommodation space 10D. Or, the heat on the heater unit 20 side is transferred in the surface direction (heat sink direction). The first and second heat reflecting layers /

heat guiding layers

64A and 64B may be brought into close contact with both sides of the separation wall 60. In this case, by using a so-called raw substrate (a material in which thin copper foils are attached to both surfaces of a material such as glass epoxy or paper phenol, which is called a copper-clad laminate), the isolation wall 60 and the first and first and the like are used. The second heat reflecting layer /

heat guiding layer

64A and 64B can be integrally configured. Further, the first and second heat-reflecting layers / heat-conducting

layers

64A and 64B may be formed by applying the heat-reflecting paint to the outer cylinder 13 and the isolation wall 60.

As described above, between the cylinder portion 73 and the substrate 50, the outer cylinder 13, the first gap 62A, the first heat reflection / heat guide layer 64A, the isolation wall 60, the second heat reflection / heat guide layer 64B, and the second gap 62B. By arranging the above, the heat of the heater unit 20 is less likely to be transferred to the substrate 50, and the heat can be released to the heat sink side, especially during continuous smoking. can. In this embodiment, the case where the structure is at least three layers (first heat reflecting layer / heat guiding layer 64A, isolation wall 60, second heat reflecting layer / heat guiding layer 64B) is exemplified except for the air layer. The present invention is not limited to this, and when the air layer is removed, it is preferably two or more layers, preferably three or more layers, and more preferably four or more layers.

Returning to FIG. 5, the front housing 10A is provided with a separable heat sink 65. The heat sink 65 has a heat dissipation structure having unevenness 65A on the outer peripheral surface side. The heat sink 65 is connected to the isolation wall 60 and the second heat reflecting layer / heat guiding layer 64B via the claws 65B. As a result, the heat of the isolation wall 60 and the like can be positively released to the outside of the housing. Further, a heat dissipation hole 66 is formed in the heat sink 65. The heat radiating hole 66 plays a role of discharging the heat of the substrate accommodating space 10D to the outside by communicating the substrate accommodating space 10D with the outside air. When the heat sink 65 is made of a metal material, the heat sink 65 and the first and / or the second heat reflecting layer /

heat guiding layers

64A and 64B are bonded to each other with a material having high heat conductivity such as solder to improve heat dissipation. You can also do it. For example, when the isolation wall 60 and the first and second heat-reflecting layers / heat-conducting

layers

64A and 64B are configured by the above-mentioned raw substrate, the heat sink 65 with respect to the first and second heat-reflecting layers / heat-conducting

layers

64A and 64B. May be soldered to form a heat dissipation module as a whole, and a member independent of the housing 10.

Further, although the case where the heat sink 65 is brought into contact with the second heat reflecting layer / heat guiding layer 64B is exemplified here, the present invention is not limited to this, and the heat sink 65 is separated from the isolation wall 60 or the first heat reflecting layer / heat conducting layer. It may be brought into contact with 64A.

<How to assemble smoking equipment>
Next, an example of how to assemble 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.

(Assembly of internal heating module)
As shown in FIG. 2, the board-side terminal portion 52 of the substrate 50 and the connection terminal portion 35 of the heater portion 20 are connected via the wiring 63, and the heater portion 20 is connected to the opening 75A of the heater support 70. On the other hand, insert it from the back side toward the front side. The leg portion 46 of the cleaning portion 40 is inserted into the leg portion opening 75B of the heater support 70 from the front side to the back side. As a result, the internal heating module is completed by the substrate 50, the wiring 63, the heater unit 20, the heater support 70, and the cleaning unit 40.

(Preparation of the back housing)
The clogs 47 and the operation portion 120 integrally formed are set in the heating space cap region 88 of the rear housing 10B. After that, the internal heating module is set in the substrate accommodation space 10D of the rear housing 10B while inserting the substrate 50. Further, the cylinder portion 73 is set in the internal heating module.

(Preparation of heat dissipation module)
The first and second heat-reflecting layers / heat-conducting

layers

64A and 64B are set on both sides of the isolation wall 60, and the heat sink 65 is bonded to the second heat-reflecting layer / heat-conducting layer 64B by soldering or the like. Complete the heat dissipation module. In this way, the heat dissipation module in which the separation wall 60, the first and second heat reflection layers / heat guide layers 64A and 64B, and the heat sink 65 are integrated is set in the back housing 10B.

(Conclusion of housing)
When the above preparations are completed, the back side housing 10B and the front side housing 10A are connected to complete the assembly of the entire smoking tool 1.

<Power control device>
Next, the power control device 101 mainly provided on the substrate 50 of the smoking tool 1 will be described. As shown in FIG. 6A, the power control device 101 receives power from the first and second

power receiving connectors

54A and 54B connected to the external power source 1001 to be DC and the first or second

power receiving connectors

54A and 54B. It is controlled by a power control circuit 53 that receives power, an input switch 55 that operates the power control circuit 53, a temperature control volume 57, an LED 56 that informs the user of the control state of the power control circuit 53 by light, and a power control circuit 53. It is configured to include a board-side terminal portion 52 to which power is supplied.

The power control circuit 53 is a gate that turns on / off the current supplied from the computing device 110 composed of a microcomputer, a clock element, a register, etc., and the first or second

power receiving connectors

54A, 54B to obtain a pulse current waveform. It has a device 128 and a smoothing circuit 130 that smoothes (averages) the pulsed voltage that has passed through the gate device 128. The smoothing circuit 130 has a coil 132 connected in series to the board-side terminal portion 52 and a capacitor 134 connected in parallel to the board-side terminal portion 52. The smoothing circuit 130 may be omitted.

The gate device 128 is, for example, a transistor, and switches ON / OFF of the current based on the gate signal from the calculation device 110. The calculation device 110 receives an operation signal from the input switch 55 and the temperature adjustment volume 57, generates a desired gate signal, and at the same time, switches ON / OFF of the LED 56 based on the control state. The drive power required by the arithmetic unit 110, the input switch 55, the temperature control volume 57, and the LED 56 is supplied from the power control circuit 53 by wiring (not shown).

With the above configuration, the power control device 101 performs so-called PWM control (pulse width modulation control) and changes the width (duty ratio) of the pulses emitted at regular intervals to obtain an average voltage (average output). Control.

<External power supply>
The external power supply 1001 is a so-called mobile battery, which is a DC power supply 1050 composed of a lithium ion battery or the like, a connector 1080 that supplies the DC power supply 1050 to the outside, and a current detection mechanism that measures the current value supplied to the connector 1080. 1010, a voltage detection mechanism 1020 that measures the voltage value supplied to the connector 1080, a cutoff mechanism 1040 that cuts off the power supplied to the connector 1080, and current values and voltage values of the current detection mechanism 1010 and the voltage detection mechanism 1020. Based on this, it has a computer 1030 that cuts off the power supply by the cutoff mechanism 1040. The safety device 1060 is configured by the current detection mechanism 1010, the voltage detection mechanism 1020, the cutoff mechanism 1040, and the computer 1030. When a current exceeding the upper limit current threshold value or a voltage exceeding the upper limit voltage threshold value is output from the connector 1080, the safety device 1060 is activated and the power supply is cut off for a certain period of time. It is preferable that the voltage detection mechanism 1020 is omitted and the current detection mechanism 1010 detects the current to activate the safety device 1060. Of course, as the external power supply 1001, one that does not have the safety device 1060 may be adopted.

The external power supply 1001 is, for example, a mobile battery with 5V specifications. Further, in the safety device 1060, the upper limit current threshold value is often set to about 3.0 A or more. Here, a mobile battery is illustrated as an external power source 1001, but an AC-DC adapter (a device connected to a commercial power source that converts alternating current to direct current power) connected to a commercial power source via a cable is referred to as an external power source 1001. You can also do it. In addition, the mobile battery may be connected to the power control device 101 via a cable.

<Control configuration of power control device>
FIG. 6B shows a control configuration (control function block) realized by the power control program of the power control device 101. The power control device 101 includes a reference power control unit 1200, a high power control unit 1210, a mode control unit 1230, and an output manual adjustment unit 1250.

The reference power control unit 1200 operates the heater unit 20 in a reference power mode that is a desired reference power. The high power control unit 1210 operates the heater unit 20 in a high power mode in which the power is larger than the reference power. The mode control unit 1230 switches between the operation in the reference power mode and the operation in the high power mode. In the case of PWM control, the pulse width of the reference power mode is set small, and the pulse width of the high power mode is set large. The ratio of the actual pulse width to the maximum pulse width is referred to as a duty ratio. The high power control unit 1210 may control the heater unit 20 to operate while switching the power value in a plurality of stages within a range larger than the reference power. For example, at the start of the high power mode, the power value can be gradually increased from the reference power. Similarly, in the latter half of the high power mode, the power value can be gradually lowered toward the reference power.

In detail, the mode control unit 1230 includes a high power-reference power automatic switching unit 1231, a reference power-non-heating automatic switching unit 1232, a high power-reference power operation switching unit 1233, a high power start unit 1234, and a reference power-non-heating unit. It has an operation switching unit 1235.

The high power-reference power automatic switching unit 1231 automatically (forces) switches to the reference power mode when the operation time in the high power mode elapses from the large power upper limit time (for example, 30 seconds). The reference power-non-heating automatic switching unit 1232 puts the heater unit 20 in the non-heating state (standby state) when the operation time in the reference power mode elapses from the reference power upper limit time (for example, 5 minutes).

The high power-reference power operation switching unit 1233 receives the "temperature lowering operation" from the input switch 55 which is the operation unit during the high power mode, and switches to the reference power mode. The reference power-non-heating operation switching unit 1235 receives the "non-heating operation (OFF operation)" from the input switch 55 during the reference power mode, and switches the heater unit 20 to the non-heating state. The high power start unit 1234 accepts the "heating start operation (ON operation)" from the input switch 55 when the heater unit 20 is not heated, or the "heating operation" from the operation unit in the reference power mode. Switch to high power mode. In this embodiment, the "heating start operation (ON operation)" and the "heating operation" are long-press operations of the input switch 55 (for example, long-press operation for 1 second or longer), and "temperature lowering operation". The "operation" is a "long press release operation" after the long press operation of the input switch 55. The "non-heating operation (OFF operation)" is a short-press operation of the input switch 55 (for example, a short-press operation of less than 1 second).

The details will be described later, but by making the "heating start operation (ON operation)" and "heating operation" more complicated or time-consuming than the "non-heating operation (OFF operation)", it can be easily increased. It is designed not to shift to power mode. On the other hand, by making the "non-heating operation (OFF operation)" a simple or short-time operation, it is possible to easily shift to the standby state.

Further, in the present embodiment, the "heating start operation (ON operation)" and the "heating operation" are the same operation, and the same operation is performed to shift to the "high power mode". In other words, the transition from the "standby state" to the "reference power mode" is not accepted. Further, the "non-heating operation (OFF operation)" accepts only the "reference power mode", and does not accept the transition from the "high power mode" to the "non-heating state". In this way, by limiting the operation order of "heating start"-> "high power mode"-> "reference power mode"-> "non-heating state", it is simple (only two types of operation patterns) and convenient for the user. High operation can be realized.

The high power control unit 1210 further has a slow start control unit 1215. The slow start control unit 1215 regulates the supply current and / or the supply voltage to the heater unit 20 at the start of operation in the high power mode. More specifically, the regulated amount of the slow start control unit 1215 is set to a level at which the power supplied to the heater unit 20 does not exceed the upper limit current threshold value and / or the upper limit voltage threshold value of the safety device 1060 of the external power supply 1001. .. As a result, the power supply from the external power supply 1001 is not cut off by the safety device 1060.

The output manual adjustment unit 1250 increases or decreases the output at an arbitrary timing in each of the high power mode and / or the reference power mode. Specifically, it accepts the volume operation input from the temperature control volume 57 and outputs the output within the range from the maximum value to the minimum value in the high power mode and / or within the range from the maximum value to the minimum value in the reference power mode. adjust. The concept of "accepting the volume operation input from the temperature adjustment volume 57" includes the temperature adjustment volume 57 at timings such as every clock, every main loop of the program, every pulse cycle, every time the mode is changed, every fixed time, and so on. This includes the case where the set value of is read and the pulse width is calculated and determined based on the set value.

In the present embodiment, when the resistance value of the heater unit 20 at room temperature is 1.5Ω to 2.5Ω (here, 2Ω), the duty ratio in the high power mode is 30% or more by the output manual adjustment unit 1250. It is controlled so as to generate a fluctuation range. Specifically, it is possible to adjust from 100% (maximum value) to 60% (minimum value). Further, the duty ratio in the reference power mode is controlled by the output manual adjustment unit 1250 so as to generate a fluctuation range of 20% or more. Specifically, it is possible to adjust from 53% (maximum value) to 26% (minimum value). When the resistance value of the heater unit 20 at room temperature is 0.5Ω to 1.5Ω (for example, 1Ω), the duty ratio in the high power mode should have a fluctuation range of 15% or more, and the reference power mode should be used. The duty ratio is controlled so as to generate a fluctuation range of 10% or more.

In particular, when a mobile battery is used as the external power supply 1001, the output and voltage differ depending on the manufacturer, individual differences within the same manufacturer, battery charge rate, degree of battery deterioration, etc., and actually 4.75V to 5 Variation of about .25V occurs. This variation width (1.0 to 1.1052 times based on 4.75 V) is squared when converted to the output (W), so it becomes 1.0 to 1.2216 times. It gets even bigger. The temperature control volume 57 is effective in absorbing this variation width, and is preferably configured so that the maximum duty ratio is 1.10 times or more the minimum duty ratio, and more preferably 1.20 times or more. And. The maximum duty ratio is 1. It is more preferably 30 times or more, and even more preferably 1.50 times or more. Since the temperature adjustment volume 57 uses a rotary variable resistor, the duty ratio can be adjusted in multiple stages (for example, more than 100 stages).

<Control flow of power control device>
7 and 8 show an operation flow and a timing chart by the power control program. First, in step S300, when the external power supply 1001 is connected to the smoking tool 1, the power supply is turned on in the unheated state, and the process proceeds to step S310 to initialize the power control circuit 53. Initialization means resetting the control information based on the previously input operation mode. After that, the process proceeds to step S320 to enter a standby state (non-heating state) for waiting for an operation input from the user. Even if the input switch 55 is in the long-pressed state from the stage before the power is turned on for some reason and the long-press release operation (warming operation) is performed in the standby state (step S322), the operation is performed. Becomes invalid and returns to step S320, and remains in the standby state. If the input switch 55 is in the long-pressed state from the stage before the power is turned on, and the initialization is completed by the subsequent power-on, the process automatically proceeds to step S334 to determine the long-pressed operation. May be done.

When a short press operation is input from the input switch 55 in step S320 (step S332), the operation becomes invalid and returns to step S320, and remains in the standby state (see FIG. 8A). That is, even if the user accidentally presses the input switch 55 momentarily, the heating is not started. On the other hand, when the long press operation (heating start operation) is received in step S320 (step S334), the process proceeds to step S340 to activate the high power start unit 1234 and start heating in the high power mode (step S340). (See FIG. 8 (A)). As a result, at the start of smoking, quick heating in the high power mode is realized. Each time heating in the high power mode is started, a timer for counting the high power upper limit time (for example, 30 seconds) is started. When the input switch 55 is pressed in step S320, the preheating by the weak output is temporarily started at the same time, and when it is determined in the step S332 that the short press operation is performed, the preheating is stopped and the preheating is stopped and the preheating is stopped. If it is determined that the operation is a long press, the preheating may be changed to the heating in the high power mode. Further, in the case of the high power mode of step S340 via step S334, the slow start control described later is executed.

After the start of heating in the high power mode (step S340) and before the high power upper limit time (for example, 30 seconds), when the long press release operation (warming operation) of the input switch 55 is performed (step S352), step S360 is performed. The process proceeds to transition to the reference power mode by the high power-reference power operation switching unit 1233 (step S360) (see FIG. 8A). As a result, the user can easily transition to the reference power mode at a desired time while checking the smoking condition in the high power mode, can prevent power waste of the external power source 1001, and can suppress overheating. On the other hand, in the high power mode of step S340, if the long press operation of the input switch 55 continues for the large power upper limit time (for example, 30 seconds) or more, the process proceeds to step S354 to activate the high power-reference power automatic switching unit 1231. Then, the mode automatically shifts to the reference power mode (step S360) (see FIG. 8A). By the way, while the high power mode of step S340 via step S334 is maintained, the long press operation is continued and after the transition to the reference power mode (step S360), the long press release operation (temperature lowering operation) of the input switch 55 is performed. However (step S356), the operation becomes invalid and returns to step S360, and the reference power mode remains (see FIG. 8A). Each time heating in the reference power mode is started, a timer for counting the reference power upper limit time (for example, 5 minutes) is started.

In the reference power mode (step S360), when a long press operation (heating start operation) is received within the reference power upper limit time (for example, 5 minutes) (step S372), the high power start unit 1234 is activated and the step is performed. Returning to S340, heating in the high power mode is started again (see FIG. 8A). As a result, even during smoking in the reference power mode, additional heating in the high power mode becomes possible as needed. For example, in the latter half of smoking, when the taste becomes weak, the taste can be strengthened by additional heating. In addition, additional heating is effective even when the first long press operation is released too early. If the user momentarily shifts to the high power mode and then returns to the reference power mode, the user can intentionally reset the timer of the reference power upper limit time to extend the smoking time. In the case of the high power mode of step S340 via step S372, the slow start control described later is not executed.

Further, in the reference power mode (step S360), when a short press operation is input from the input switch 55 within the reference power upper limit time (for example, 5 minutes) (step S374), the reference power-non-heating operation switching unit. 1235 is activated and transitions to the standby state (step S320) (see FIG. 8A). This is an operation to end smoking by oneself. Further, when the operation duration of the reference power mode (step S360) reaches the reference power upper limit time (for example, 5 minutes) or more, the process proceeds to step S376 to activate the reference power-non-heating operation switching unit 1235 and automatically. Transition to the standby state (step S320) (see FIG. 8B). This is an action to automatically end smoking. The long press operation is continued to shift to the reference power mode (step S360) while the high power mode of step S340 via step S334 is maintained, and the reference power upper limit time (for example, 5 minutes) is continued while the long press operation is continued. Even when the above is reached, as shown by the dotted line in FIG. 7, the process proceeds to step S376 and automatically transitions to the standby state (step S320).

When the input switch 55 is pressed in step S360, temporary heating equivalent to a large amount of electric power is started at the same time, and when it is determined in step S374 that the operation is a short press operation, the temporary heating is stopped (step S320). ), If it is determined in step S372 that the operation is a long press, the temporary heating may be followed by the transition to the main heating in the high power mode (step S340).

In FIGS. 8A and 8B, the control state (VR) of the output manual adjustment unit 1250 is the maximum output (VR-MAX), the duty ratio in the high power mode is 100%, and the reference power mode is used. The case where the duty ratio is set to 53% is illustrated. On the other hand, FIG. 8C is a case where the control state (VR) of the output manual adjustment unit 1250 is set to the minimum output (VR-MIN) in the same control flow and timing chart as in FIG. 8B. That is, the duty ratio of heating in the high power mode is set to 60%, and the duty ratio of heating in the reference power mode is set to 26%. Of course, it is also possible to adjust the level in the middle between the minimum value (VR-MIN) and the maximum value (VR-MAX) by the volume operation input from the temperature adjustment volume 57.

<Slow start control flow>
FIG. 9 shows the timing chart of the slow start control unit 1215 with the elapsed time axis enlarged. The slow start control unit 1215 controls so that the final duty ratio of the high power mode is reached while increasing the duty ratio with the passage of time at the start of the operation of the high power mode in step S340. Here, the duty ratio is gradually increased. In the middle, a step may be included to temporarily reduce the duty ratio. When the high power start unit 1234 is started by the long press operation (heating start operation) in the reference power mode (step S360), this slow start control is not performed.

Specifically, in FIG. 9A, the control state (VR) of the output manual adjustment unit 1250 is the maximum output (VR-MAX), and the process of increasing the duty ratio to 100% in the high power mode in four steps is performed. show. When the long press operation (heating start operation) is accepted (step S334), heating in the high power mode is started (step S340), and first, the first step is heating at a duty ratio of 40% for 1 second (step S340A). The second stage is heated at a duty ratio of 60% for 1 second (step S340B), the third stage is heated at a duty ratio of 80% for 1 second (step S340C), and the fourth stage is heated at a duty ratio of 100%, which is the final output. (Step S340D). When the fourth stage elapses for 27 seconds, the mode automatically shifts to the reference power mode.

Further, FIG. 9B shows a process in which the control state (VR) of the output manual adjustment unit 1250 is the minimum output (VR-MIN), and the duty ratio is increased to 60% in the high power mode in four steps. When the long press operation (heating start operation) is accepted (step S334), heating in the high power mode is started (step S340), and first, the first step is heating at a duty ratio of 24% for 1 second (step S340A). The second stage is heated with a duty ratio of 36% for 1 second (step S340B), the third stage is heated with a duty ratio of 48% for 1 second (step S340C), and the fourth stage is heated with a duty ratio of 60%, which is the final output. (Step S340D).

The resistance value of the heater unit 20 is generally small at low temperatures and large at high temperatures. At the start of heating by the heater unit 20, the temperature of the heater unit 20 becomes low, so if the voltage of the external power supply 1001 (5V specification) is directly applied to the heater unit 20, the current supplied from the external power supply 10001 becomes the external power supply 10001. The threshold value of the safety device 1060 is exceeded (for example, over 3.0 A), and as a result, as shown by the dotted line F in FIG. 9 (A), excessive power is applied to the heater unit until the temperature of the heater unit 20 is sufficiently raised. Can be supplied to 20. Actually, before that, the safety device 1060 of the external power supply 10001 is activated and cuts off the power supply.

Therefore, in the present embodiment, the slow start control unit 1215 narrows down the electric power (average voltage or average current) supplied to the heater unit 20 at low temperature, and then the temperature of the heater unit 20 rises and the resistance value increases. After that, increase the duty ratio to the final duty ratio in the high power mode. As a result, an excessive current of, for example, 3.0 A or more does not always flow in the heater unit 20, and it is not necessary to start the safety device 1060 of the external power supply 1001. In particular, in the present embodiment, the safety device 1060 of the external power supply 1001 is prevented from being activated by controlling the safety side so that a current exceeding 2.0 A does not flow.

In this embodiment, a plurality of definitions of the slow start period (time zone) by the slow start control unit 1215 can be considered. One is the idea defined by the power standard, and in a broad sense, the power (average current x average voltage) supplied to the heater unit 20 should be equal to or less than the final target value in the high power mode. The time zone to be controlled (power standard slow start period in a broad sense). Further, in a narrow sense, a time zone in which the power supplied to the heater unit 20 (average current x average voltage) is controlled to be maintained at 80% or less of the final target value in the high power mode (power reference throw in the narrow sense). Start period). The other is the idea of defining by the average current value or the average voltage value. Explaining the duty ratio of the current control shown in FIG. 9, in a broad sense, the duty ratio is higher than the duty ratio which is the final target of the high power mode. It is a small controlled time zone (current / voltage reference slow start period in a broad sense). Further, in a narrow sense, it is a time zone in which the duty ratio is controlled to be 80% or less of the duty ratio which is the final target of the high power mode (current / voltage reference slow start period in the narrow sense).

At this time, the current / voltage reference slow start period (total time of the first to third stages) in a broad sense is preferably 10 seconds or less, and if it is larger than that, the heating speed is delayed, which is convenient at the start of smoking. Sex is reduced. Preferably, the current / voltage reference slow start period in a broad sense is 8 seconds or less. In this embodiment, it is set to 5 seconds or less (actually 3 seconds). On the other hand, in order not to activate the safety device 1060 of the external power supply 1001, the current / voltage reference slow start period in a broad sense is preferably 2 seconds or more.

The current / voltage reference slow start period in a narrower sense is preferably 8 seconds or less, and if it is longer than that, the heating speed is delayed and the convenience at the start of smoking is reduced. Preferably, the current / voltage reference slow start period in the narrow sense is 6 seconds or less. On the other hand, in order not to activate the safety device 1060 of the external power supply 1001, the current / voltage reference slow start period in the narrow sense is preferably 1 second or longer.

Similarly, as shown in FIG. 9A, the power standard slow start period (N) in a broad sense is preferably 10 seconds or less, and if it is larger than that, the heating speed is delayed and the convenience at the start of smoking is convenient. Decreases. Preferably, the power reference slow start period in a broad sense is 8 seconds or less. In this embodiment, it is set to 5 seconds or less (actually 3 seconds). On the other hand, in order not to activate the safety device 1060 of the external power supply 1001, the power standard slow start period in a broad sense is preferably 2 seconds or more.

The power standard slow start period (N1 + N2 + N3) in a narrower sense is preferably 8 seconds or less, and if it is longer than that, the heating speed is delayed and the convenience at the start of smoking is reduced. Preferably, the power reference slow start period in the narrow sense is 6 seconds or less. On the other hand, in order not to activate the safety device 1060 of the external power supply 1001, the power reference slow start period in the narrow sense is preferably 1 second or longer.

In the present embodiment, the slow start control unit 1215 exemplifies the case where the slow start is realized by gradually increasing the duty ratio, but the present invention is not limited to this. For example, as shown in FIG. 10A, the slow start control unit 1215 includes a constant current control device 150 arranged in the power control circuit 53, and heaters only a constant current or a current whose upper limit is regulated. You may let it flow to the part 20. As the constant current control device 150, for example, a constant current diode or the like can be used.

Further, for example, as shown in FIG. 10B, the slow start control unit 1215 includes a variable resistance device 160 arranged in series with the heater unit 20 in the power control circuit 53, and the resistance value of the variable resistance device 160 can be determined. It may be varied by the calculation device 110. During the slow start period, the resistance value of the variable resistance device 160 is increased to compensate for the shortage of the resistance value of the heater unit 20. After the end of the slow start period (after raising the temperature of the heater unit 20), the resistance value of the variable resistance device 160 may be controlled to be small. As the variable resistance device 160, a digital potentiometer or the like can be used.

In addition, in FIGS. 8 and 9, except for the slow start, the case where the electric power is maintained constant during the operation of the high power mode and / or the reference power mode is illustrated, but as shown in FIG. 11, for example, each mode is illustrated. In the middle of the operation of, the power may be controlled to be gradually reduced or increased.

<How to use smoking equipment>
As shown in FIG. 12A, the cigarette T is inserted into the tubular portion 73 through the opening K for inserting the cigarette in the housing 10. When the tobacco T is strongly pushed inside, the heating region 22 of the heater portion 20 pierces the inside of the leaves of the tobacco T. At this time, the cleaning portion 40 is pushed toward the rear end side together with the leg portion 46, the clogs portion 47, and the operation portion 120 by the tip of the cigarette T. In this state, the USB female terminal (not shown) of the external power supply 1001 serving as a mobile battery is directly inserted into the first power receiving connector 54A to integrate the smoking device 1 and the external power supply 1001. The user may hold either or both of the smoking equipment 1 and the external power supply 1001 by hand. Since the smoking tool 1 and the external power supply 1001 are integrated, it is easy to hold by hand. Further, since the smoking tool 1 has an extremely small outer dimension L in the insertion axis C direction, for example, when smoking while holding the external power source 1001, the angle of the cigarette T held by the mouth and the gripping angle of the external power source 1001 are obtained. The bending moment acting on the first power receiving connector 54A can be small due to the displacement.

After that, when the switch 55 is pressed and held via the external operation unit 11C to start heating the cigarette T in the high power mode, the temperature of the leaves and the cylinder portion 73 of the cigarette T rises, and nicotine and the like contained in the leaves are charged. Ingredients vaporize and become ready for smoking. Smoking of cigarette T is possible even while the switch 55 is pressed and held. After that, while smoking, the long press is released to shift to the reference power mode, and the switch 55 is pressed and held again to easily shift to the high power mode. When the smoking of the cigarette T is completed through the reference power mode, the switch 55 is briefly pressed (may be automatically turned off by the timer) to end smoking. Press and hold the switch 55 to switch to the high power mode, release the long press to switch to the reference power mode, and press and hold the switch 55 to end smoking. As you can choose, it is very convenient. After that, as shown in FIG. 4, if the operation unit 120 is slid in the axial direction, the cigarette is pushed toward the front side by the cleaning unit 40, so that the cigarette T may be pulled out in the axial direction by hand. The internal cleaning unit 40 reciprocates relative to the heater unit 20 in the axial direction, so that the residue can be scraped off. If the next new cigarette T is set in the smoking tool 1, it is possible to start new smoking as it is. In the case of continuous smoking of a plurality of cigarettes T, since the cylinder portion 73 and the heater portion 20 are already at high temperature at the start of smoking of the cigarettes T later, the long press of the switch 55 is released early and the high power mode is performed. It is also possible to end. By the way, in the reference power mode, smoking is possible for several minutes by keeping the leaves of the tobacco T at an appropriate temperature.

As shown in FIG. 12B, the external power supply 1001 serving as a mobile battery may be connected to the second power receiving connector 54B by using a cable 2001 having a MicroUSB connector (male). Since the smoking tool 1 is pulled vertically downward by the gravity of the cable 2001 and the external power supply 1001, if the second power receiving connector 54B is connected so as to face vertically downward, the smoking tool 1 can be inserted even with a small holding force. The axis C can be stabilized in a posture close to horizontal. In other words, the external force that tries to bend the cigarette during smoking becomes small, and the cigarette becomes difficult to break. Therefore, when the user grips the smoking tool 1 by hand, the load acting on the hand is small, and the user can smoke in a comfortable posture. In particular, in the present embodiment, the smoking tool 1 is made lightweight and compact by not incorporating a battery for heating the heater, and further, the position of the second power receiving connector 54B formed on the side surface and the cigarette T to be inserted are located. Superimpose in the axial direction. As a result, even if an external force (for example, the weight of the battery or cable itself) acts on the second power receiving connector 54B, the bending moment acting on the cigarette while smoking (while holding) can be minimized, so that the cigarette bends or breaks. At the same time, it is possible to prevent the smoking tool 1 from falling out of the cigarette. There is no need to hold the cigarette T strongly with the mouth, and there is an advantage that it is hard to get tired.

By the way, since the MicroUSB connector of the second power receiving connector 54B has low strength, it is easily damaged when a bending moment acts in a direction orthogonal to the connection direction (detachment direction). In the present embodiment, the second power receiving connector 54B is formed on the front side of the side surface of the housing 10, and the cable 2001 having the MicroUSB connector (male) can be hung in the vertical direction. Since the bending moment with respect to the connection direction does not act on the 54B, the damage is suppressed. As the compact USB connector, a MiniUSB connector (male or female) or the like can be adopted in addition to the MicroUSB. As for the type, C type may be adopted in addition to A type and B type.

FIG. 12C shows a state in which the AC-DC adapter 3001 connected to the external power outlet serving as a commercial power source is connected to the second power receiving connector 54B of the smoking tool 1 by using the cable 4001. The AC-DC adapter 3001 generally has a USB type A or USB type C female connector. The cable 4001 connected to the female connector has a MicroUSB connector (male) at its tip, and the MicroUSB connector (male) is connected to the second power receiving connector 54B. In this case as well, as in FIG. 12B, the smoking posture of the smoking tool 1 is stabilized by the cable 4001 and the AC-DC adapter 3001, so that it is possible to smoke in a comfortable posture. The cable 4001 and the AD-DC adapter 3001 may be integrated.

According to this smoking tool 1, a mobile battery (external power source 1001) that can be used with a smartphone or the like can be used as it is for smoking. For example, a user who smokes frequently can use a general-purpose, large-capacity mobile battery to continuously smoke with the smoking device 1, so he / she has multiple smoking devices with a built-in small-capacity battery and charges all of them individually. It eliminates the complexity of carrying around. Moreover, since the smoking tool 1 is extremely compact, it does not get in the way when it is carried around.

Furthermore, this smoking tool 1 is lightweight. As a result, for example, if the smoking tool 1 and the external power supply 1001 are connected by using a long cable 2001 of 50 cm or more and the cigarette T attached to the smoking tool 1 is sucked by the mouth, a so-called sucking cigarette state is obtained. Since both hands are free, it is possible to smoke while working. If the external power supply 1001 is used as the AC-DC adapter 3001, there is no concern that the battery will run out, and smoking will be possible for a long time. In particular, in the case of the present smoking tool 1, since the second power receiving connector 54B is formed on the side surface of the housing 10, when the cable 2001 is hung in the vertical direction, the smoking tool 1 is in a posture of holding a cigarette by itself, and the cigarette T Since the load acting on the mouth that holds the cigarette is small, it is not tiring.

<Modification example of arrangement of power receiving connector>
In the smoking tool 1 of the present embodiment, a case where the first power receiving connector 54A (male), which is a USB standard, is arranged so as to project toward the back side on the back side surface of the housing 10 is illustrated. Not limited to. For example, as in the modified example of the present embodiment shown in FIG. 13, the first power receiving connector 54A may be arranged so as to project on the side surface of the housing 10 in the direction orthogonal to the insertion shaft C. At this time, as shown in FIG. 13 (A), the width direction Wa of the first power receiving connector 54A can be made parallel to the insertion shaft C, and as shown in FIG. 13 (B), the first power receiving connector. The width direction Wa of 54A can also be orthogonal to the insertion axis C. It should be noted that the angle difference between the direction of the insertion shaft C and the connection direction of the first power receiving connector 54A (male) can be set diagonally so as to be in the range of 0 degrees to 90 degrees. In this way, when the smoking tool 1 and the external power source 1001 are combined, the whole becomes an L-shape. Therefore, by grasping the external power source 1001 by hand, it is possible to easily obtain a smoking posture with less burden.

<Deformation example of the cylinder part>
In the smoking tool 1 according to the modified example of FIG. 14, 0.7 × G2 <G1 <1. The case of setting in the range of 5 × G2 is shown. It is preferably set in the range of 0.8 × G2 <G1 <1.3 × G2, and more preferably G2 <G1 <1.3 × G2. By doing so, the maximum accommodation length G1 of the tubular portion 73 can be approximated to the heating distance G2 of the leaf portion by the heater portion 20, so that only the leaf portion of the cigarette can be heated in a limited manner. Waste of heat is suppressed and power saving can be achieved.

It should be noted that the smoking device of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
