  • the housing pipe 11 may have the form of a hollow pipe.
  • the carrier chamber 12 may be disposed at one end portion of the housing pipe 11 in the longitudinal direction.
  • the carrier chamber 12 according to an embodiment may be filled with the propellant therein.
  • the inside of the carrier chamber 12 may maintain a state of high pressure.
  • the propellant filled in the carrier chamber 12 may exist in a gaseous state at atmospheric pressure but may be stored in a liquid state inside the carrier chamber 12 due to the high pressure.
  • the pressure inside the carrier chamber 12 may be higher than atmospheric pressure, desirably a pressure of 2 times the atmospheric pressure (2 bar), and more desirably a pressure of 6 times the atmospheric pressure (6 bar).

  • the mouthpiece portion 13 may be disposed at the other end portion of the housing pipe 11 in the longitudinal direction.
  • the other end portion of the housing pipe 11 in the longitudinal direction may refer to the end portion opposite to the carrier chamber 12.
  • the mouthpiece portion 13 according to an embodiment may be a part that the mouth of the user of the powder inhalation device 10 contacts to inhale the powder.
  • the first valve 14a and the second valve 14b may open when the user of the powder inhalation device 10 starts inhaling the powder and may close when the user ends inhaling the powder.
  • the first valve 14a may be disposed between the housing pipe 11 and the carrier chamber 12. It may be desirable that the inside of the carrier chamber 12 according to an embodiment be maintained at a pressure higher than atmospheric pressure, and it may be desirable that the pressure inside the housing pipe 11 according to an embodiment be maintained lower than the pressure inside the carrier chamber 12. In this case, when the user's inhalation starts and the first valve 14a is opened, a liquid-type propellant filled in the carrier chamber 12 may vaporize and flow into the housing pipe 11 through the first valve 14a.
  • the second valve 14b may be disposed between the housing pipe 11 and the mouthpiece portion 13.
  • the second valve 14b according to an embodiment may be opened only when the user bites the mouthpiece portion 13 and inhales so that the user may inhale the powder only when desired.

  • the powder supply 15 may be disposed between the first valve 14a and the second valve 14b.
  • the powder supply 15 may spray powder into a path formed by the housing pipe 11.
  • the powder supply 15 may spray powder from a direction perpendicular to the path formed by the housing pipe 11.
  • the powder supply 15 may be disposed tilted obliquely to the path formed by the housing pipe 11. In this case, since the initial spray direction of the powder supplied by the powder supply 15 and the moving direction of the propellant transferred along the housing pipe 11 form an acute angle, more efficient transfer may be possible.
  • the powder inhalation device 10 may further include a carrier cartridge 16.
  • the carrier cartridge 16 may refill the carrier chamber 12 with a propellant.
  • the carrier cartridge 16 according to an embodiment may be disposed at the opposite end portion to one end portion of the carrier chamber 12 facing the housing pipe 11.
  • the carrier cartridge 16 according to an embodiment may include the same propellant material as the propellant material filled in the carrier chamber 12.
  • the propellant according to an embodiment may be HFA-134a (1, 1, 1, 2-Tetrafluorodthane), propylene glycol (co-solvents propylene glycol), polyethylene glycol, HAF227 (1, 1, 1, 2, 3, 3, 3-Heptafluoropropane), 152a (1, 1-Difluoroethane) and/or ethanol or a mixture thereof.
  • the powder inhalation device 10 may further include a controller 17 and a switch 18.
  • the controller 17 may control the overall operation of the powder inhalation device 10. Specifically, the controller 17 may control the operation of components included in the powder inhalation device 10. In addition, the controller 17 may verify a state of each of the components of the powder inhalation device 10 to determine whether the powder inhalation device 10 is in an operable state.
  • the controller 17 may include at least one processor.
  • the processor may be implemented as an array of a plurality of logic gates or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored.
  • the processor may be implemented in other types of hardware.
  • the controller 17 may include an inhalation detection sensor.
  • the inhalation detection sensor may control the opening and closing of the first valve 14a and/or the second valve 14b by detecting when the user of the powder inhalation device 10 intends to inhale or perform an inhaling action.
  • the powder inhalation device 10 may further include a battery (not shown) capable of supplying power.
  • the first valve 14a and/or the second valve 14b may be manually opened and closed.
  • the switch 18 according to an embodiment may be disposed at a position where the thumb or index finger may be placed when the user grips the powder inhalation device 10, and when the switch 18 is clicked during inhalation, the first valve 14a and/or the second valve 14b may be opened so that the powder may be transferred.
  • FIGS. 3A, 3B , and 4 are diagrams schematically illustrating the powder supply 15 according to an embodiment.
  • the powder supply 15 may include a powder cartridge 152 in which powder may be accommodated and a powder spray 154.
  • the powder cartridge 152 may accommodate powder particles MP.
  • the powder particles MP may include a medium that may be transferred to the user.
  • the powder cartridge 152 according to an embodiment may include powder, and the powder according to an embodiment may include one cigarette's worth of nicotine medium or more.
  • the powder cartridge 152 may include an opening through which the powder particles MP are discharged. Through the opening of the powder cartridge 152, the powder particles MP may be transferred to the powder spray 154.
  • the powder spray 154 may include an opening through which the powder particles MP are discharged. Through the opening of the powder spray 154, the powder particles MP may be transferred into the housing pipe 11.
  • the powder spray 154 may include a streamlined structure. Since the powder spray 154 according to an embodiment may be inserted and disposed on the path formed by the housing pipe 11, when the propellant is transferred toward the mouthpiece portion 13, it may be desirable that the powder spray 154 have a streamlined structure in order to minimize resistance due to the powder spray 154.
  • the powder spray 154 may include a tubular shape formed in the longitudinal direction. In order to minimize resistance due to the powder spray 154 on the path along which the propellant is transferred toward the mouthpiece portion 13, it may be desirable that the powder spray 154 have a narrow and long tubular shape.
  • the powder spray 154 may be disposed tilted obliquely to the path formed by the housing pipe 11 (see FIG. 2 ). In this case, since the initial spray direction of the powder supplied by the powder supply 15 and the moving direction of the propellant transferred along the housing pipe 11 form an acute angle, more efficient transfer may be possible.
  • the powder supply 15 may include a powder cartridge 152 and a powder spray 154.
  • the powder cartridge 152 may include a plurality of powder capsules MC including a powder material.
  • the powder cartridge 152 may include an opening through which the powder capsule MC is discharged. Through the opening of the powder cartridge 152, the powder capsules MC may be transferred to the powder spray 154.
  • the powder supply 15 may further include a crushing unit 156.
  • the crushing unit 156 may crush the powder capsules MC discharged from the powder cartridge 152. Powder included in the powder capsules MC crushed by the crushing unit 156 according to an embodiment may be discharged and transferred into the housing pipe 11.
  • the powder material sprayed by the powder spray 154 may move toward the mouthpiece portion 13 together with the propellant discharged from the carrier chamber 12.
  • the propellant may be a highly evaporative material and may be quickly vaporized and/or evaporated simultaneously when discharged from the high-pressure carrier chamber, that is, the carrier chamber 12.
