Definitions

  • the present invention relates to a flavor inhaler.
  • a flavor inhaler for inhaling flavor or the like without burning a material.
  • the flavor inhaler has, for example, a chamber that accommodates a flavor generating article and a heater that heats the flavor generating article accommodated in the chamber.
  • a flavor inhaler one that has a cylindrical heat insulator on an outer side of a member that accommodates a flavor generating article is known (see Patent Literature 1).
  • Patent Literature 1 discloses that the heat insulator can be a fibrous heat insulator or a foam heat insulator. However, Patent Literature 1 does not disclose at all how to attach such a heat insulator on an outer side of the container member that accommodates the flavor generating article. Such a heat insulator tends to be weak in structural strength, and some ingenuity is needed to attach the heat insulator to an outer side of the container member.
  • An object of the present invention is to more properly attach a heat insulator to an outer side of a containing unit.
  • a flavor inhaler that is capable of heating a consumable.
  • This flavor inhaler includes a containing unit that accommodates the consumable, a heating element that heats the consumable, a heat insulating member that is provided on an outer circumference of the containing unit, and a first tape member that is attached to the heat insulating member.
  • the first tape member has a first part that extends beyond a first end part of the heat insulating member in a circumferential direction and a second part that is located on the heat insulating member or extends beyond the heat insulating member. The first part is attached to the second part.
  • the heat insulating member tends to be weak in structural strength, in a case where the heat insulating member to which the first tape member has been attached is attached to the containing unit, there is a possibility that the first tape member is detached from the heat insulating member.
  • the first part of the first tape member is attached to the second part, and therefore an adhesion strength of the first tape member can be improved.
  • the heat insulating member can be properly attached to an outer side of the containing unit, and therefore the flavor inhaler has a good heat insulating function and can precisely heat the consumable.
  • the second end part of the heat insulating member can be fixed by being directly or indirectly attached to the containing unit by the fixing part.
  • a strength of the heat insulating member can be improved by the first tape member. Specifically, a tension strength of the heat insulating member in a circumferential direction can be improved. Furthermore, since the heat insulating member can be attached to the containing unit by winding the first tape member, the heat insulating member can be wound around the containing unit while being compressed. As a result, a thickness of the heat insulating member can be easily adjusted, and therefore the flavor inhaler can have good design accuracy.
  • a flavor inhaler in which it is still harder for heat of the heated consumable to be transmitted to an outside of the device is provided.
  • the thermistor can be disposed close to the heating element, and therefore a temperature of the heating element or the containing unit can be accurately acquired.
  • an eighth aspect is arranged such that the containing unit has a cylindrical side wall part; the side wall part has a flat outer surface; and the thermistor is located outside the flat outer surface in a radial direction.
  • the thermistor is sandwiched between the first tape member and the second tape member, and therefore the thermistor can be more firmly attached to the first tape member.
  • a tenth aspect is arranged to further include a shrinkable tube that is located on an outer side of the second tape member.
  • an eleventh aspect is arranged such that a length of the first tape member in an axis direction of the containing unit is 50% or more of a length of the heat insulating member in the axis direction.
  • a thirteenth aspect is arranged such that the containing unit has an opening through which the consumable is inserted and a bottom that makes contact with an end surface of the consumable; and the heating element is disposed closer to the opening than to the bottom.
  • a fourteenth aspect is arranged such that the heating element heats the consumable from an outer side.

  • a length of the first tape member 80 in the axis direction is preferably 50% or more of a length of the heat insulating member 70 in the axis direction. This can make it harder for the heat insulating member 70 to be displaced with respect to the chamber 50 or the heating element 42 .
  • the heat insulating member 70 generally has a higher coefficient of friction than the first tape member 80 that can be formed of a resin material or the like. In this respect, since 50% or more of the heat insulating member 70 in the axis direction is covered with the first tape member 80 , frictional force applied to the shrinkable tube 46 can be reduced when the cylindrical shrinkable tube 46 is disposed on an outer side of the heat insulating member 70 and the first tape member 80 . Therefore, a cylindrical member such as the shrinkable tube 46 can be easily disposed on the outer side of the heat insulating member 70 and the first tape member 80 .
  • the heating element 42 is preferably disposed closer to the opening 52 than to the bottom 56 of the chamber 50 .
  • a leading end of the consumable 110 is less heated by the heating element 42 , and therefore a material (e.g., the smokable substance 111 ) of the consumable can be made less likely to fall off from the leading end of the consumable 110 due to contraction of the leading end of the consumable 110 caused by heating.
  • the leading end side of the consumable 110 can be cooled relative to the consumable 110 on an opening 52 side where the consumable is inserted, secondhand smoke generated by heating of the consumable can be cooled on the leading end side, and leakage of the secondhand smoke from the leading end of the consumable 110 can be made less likely to occur.
  • the configuration in which the heating element 42 is provided close to the opening 52 through which the consumable is inserted makes it possible to inhale vapor (steam) generated from the consumable 110 without condensing the vapor and is therefore effective.
  • a temperature of a desired position of the chamber 50 can be increased by heat transfer from the heating element 42 without lowering a rate of temperature rise. This contributes to efficient generation of vapor and is therefore effective.
  • the thermistor 43 is configured to measure a temperature of the consumable 110 , the chamber 50 , or the heating element 42 .
  • the thermistor 43 is electrically connected to a PCB (not illustrated) by a wire 43 a and can transmit temperature data to the PCB.
  • the thermistor 43 is preferably provided on an outer surface of the first tape member 80 . With this configuration, the thermistor 43 can be easily fixed as compared with a case where the thermistor 43 is provided on an outer surface of the heat insulating member 70 . Furthermore, in a case where the thermistor 43 is attached to the first tape member 80 with the use of the second tape member 45 , the thermistor 43 is reattachable.
  • the thermistor 43 is preferably located outside the heating element 42 in the radial direction. With this configuration, the thermistor 43 can be disposed close to the heating element 42 , and therefore can accurately acquire a temperature of the heating element 42 or the chamber 50 . Furthermore, as illustrated in FIGS. 6 and 7 , the thermistor 43 is preferably located outside the flat outer surface 62 b of the flat part 62 in the radial direction. With this configuration, the thermistor 43 can be easily disposed on the outer surface of the first tape member 80 as compared with a case where the thermistor 43 is disposed on the outer surface 66 b of the curved part 66 .
  • the configuration in which the thermistor 43 is located on the flat outer surface 62 b can widen a distance between the heat insulator 32 and the thermistor 43 , and therefore can make physical contact between the heat insulator 32 and the thermistor 43 further less likely to occur.
  • the second tape member 45 is configured to fix the thermistor 43 together with the first tape member 80 so that the thermistor 43 is sandwiched between the second tape member 45 and the first tape member 80 .
  • the second tape member 45 is attached onto the thermistor 43 , and thereby the thermistor 43 is fixed to the outer surface of the first tape member 80 .
  • the thermistor 43 is sandwiched between the first tape member 80 and the second tape member 45 , and therefore the thermistor 43 can be more firmly attached to the first tape member 80 .
  • the second tape member 45 may be omitted, and the thermistor 43 may be fixed onto the outer surface of the first tape member 80 , for example, with the use of an adhesive or the like.
  • the shrinkable tube 46 has a cylindrical shape, is disposed on an outermost side of the heater 40 , and can be configured to fix the members that constitute the heater 40 to the chamber 50 .
  • the shrinkable tube 46 can be located on an outer side of the second tape member 45 .
  • the shrinkable tube 46 can fix the heating element 42 , the heat insulating member 70 , the first tape member 80 , the thermistor 43 , and the second tape member 45 to the chamber 50 by applying force so as to press these members against the chamber 50 .
  • the heater 40 need not necessarily include the thermistor 43 and the second tape member 45 .
  • the shrinkable tube 46 can be located on an outer side of the first tape member 80 so as to make contact with the outer surface of the first tape member 80 .
  • the shrinkable tube 46 can be, for example, a heat shrinkable tube that thermally shrinks upon application of heat in a state where the shrinkable tube 46 is disposed on an outer circumference side of the members that constitute the heater 40 .
  • the members that constitute the heater 40 can be pressed against the chamber 50 by the heat shrinkage of the shrinkable tube 46 .
  • the shrinkable tube 46 is a heat shrinkable tube
  • the shrinkable tube 46 can be for example, formed of a thermoplastic resin such as perfluoroalkoxy fluorine resin (PFA).
  • PFA perfluoroalkoxy fluorine resin
  • the shrinkable tube 46 is not limited to a heat shrinkable tube and can be any member that can accomplish a similar objective.
  • a tube or the like that elastically contracts can be used as the shrinkable tube 46 .
