  • a residual liquid quantity in the liquid storage room 202 of the tank 191 is 1/3 and a headspace volume expansion coefficient (a volume expansion coefficient of the air in the residual 2/3 space in the liquid storage room 202) is 6%
  • there is approximately 100 cubic millimeters of the liquid aerosol source being extruded from the liquid storage room 202 due to the air expansion in the liquid storage room 202 of the tank 191.
  • the extruded liquid aerosol source there is approximately 20-30 cubic millimeters of the liquid aerosol source may be retained by the mesh body 193 and the wick 204.
  • the remaining 70-80 cubic millimeters of the liquid aerosol source is accumulated in the accumulation portion 223.
  • the liquid accumulation portion 223 is formed that the gap between the external circumferential surface of the cylinder portion 217 and the circumferential wall 191b of the tank 191 gradually becomes narrower towards the tip end of the protrusion portion 219 from the seal portion 222. In other words, in the vicinity of the protrusion portion 219 of the cylinder portion 217, the narrow portion 279 where the gap between the protrusion portion 219 and the circumferential wall 191b of the tank 191 becomes narrow is formed.
  • the liquid aerosol source stored in the liquid accumulation portion 223 is suctioned through the narrow portion 279 (the interval between the protrusion portion 219 and the circumferential wall 191b of the tank 191). Then, the liquid aerosol source is absorbed by the mesh body 193. In other words, the liquid aerosol source stored in the liquid accumulation portion 223 flows back to the liquid storage room 202 of the tank 191 through the narrow portion 279. At this time, since the narrow portion 279 is covered (blocked) by the external circumferential portion of the mesh body 193, a capillary force due to the mesh body 193 also applies such that the liquid aerosol source efficiently flows back to the liquid storage room 202 of the tank 191.
  • the liquid accumulation portion 223 and the external air are communicated through the notch portions 222a of the seal portion 222 and a gap between the engagement hole 198 of the tank 191 and the engagement piece 206 (engagement claw 207) of the heater holder 196.
  • the liquid accumulation portion 223 and the external air may be communicated through the notch portions 222a of the seal portion 222 and the first air-suction hole 209 of the heater holder 196. Accordingly, it is impossible to generate a pressure difference between the inside and outside the liquid accumulation portion 223. As a result, an unintentional leakage of the liquid aerosol source to the outside from the liquid accumulation portion 223 is prevented and the liquid aerosol source efficiently flows back to the liquid storage room 202 of the tank 191.
  • the horizontal engagement convex portion 102 may be disposed in the retention unit 22 and the engagement groove 158 may be disposed in the power unit 21.
  • the bending portion 106 may be disposed in the retention unit 22 and the engagement piece 142 (tip end portion 142a) may be disposed in the power unit 21. Not only the bending portion 106 but also the tip end portion 142a of the engagement piece 142 may be elastically deformed in the radial direction, and in the engagement piece 142, only the tip end portion 142a may be elastically deformed in the radial direction.
  • the annular piece 82 (elastic ring) forming the bending portion 106 is attached to the power unit 21 where the horizontal engagement convex portion 102 is disposed, and the tip end portion 142a protruding inwardly in the radial direction relatively to the engagement concave portion 155 is formed in the engagement piece 142 forming the engagement groove 158 in the retention unit 22 where the engagement groove 158 is disposed.
  • a configuration according to the present embodiment has the power unit 21 (power source), the retention unit 22 (accommodation portion) formed in a cylindrical shape and capable of accommodating the aerosol source, and the mouthpiece 23 (suction port portion) where the suction port 23a for suctioning the aerosol generated by atomizing the aerosol source is formed, wherein the power unit 21 and the retention unit 22 are connected by the rotation connection mechanism 310 and the lock mechanism 311.
  • a configuration according to the present embodiment has the main body unit 10 and the cartridge 11 configured to accommodate the aerosol source and inserted in the retention unit 22 of the main body unit 10 to be attachable to and detachable from the retention unit 22.
  • an example of the suction device 1 configured for the tobacco capsule 12 to be attachable to and detachable from is described as an example of an aerosol generation device for generating aerosol without combustion is described; however, the aerosol generation device is not limited to the configuration only.
  • a configuration without the tobacco capsule 12 such as an electrical tobacco may be provided.
  • the aerosol source including a flavor is accommodated in the cartridge 11 and the aerosol including the flavor is generated by the aerosol generation device.
  • the retention unit 22 is formed in a cylindrical shape to surround the circumference of the cartridge 11; however, the retention unit 22 is not limited to the configuration only.
  • the retention unit 22 only has to be a configuration capable of retaining the cartridge 11.
  • attachment and detachment of the cartridge 11 and the main body unit 10 is not limited to the configuration of accommodating the cartridge 11 in the retention unit 22 and being retained by the mouthpiece 23, and the configuration of simply connecting or disconnecting the pin electrodes 49 with the connection electrodes 213b, 214b is included.
  • the power unit 21 and the retention unit 22 are formed in cylindrical shapes and disposed coaxially; however, the power unit 21 and the retention unit 22 are not limited only to this configuration.
  • the power unit 21 and the retention unit 22 may be formed in different shapes.
  • a divided unit of an aerosol generation device comprises a main body portion in a cylindrical shape, an engagement piece formed in an end portion of the main body portion in an axial direction, the engagement piece extending from the end portion along the axial direction and bending in a circumferential direction of the main body portion, and a concave portion formed in an internal circumferential surface of a portion of the engagement piece bending in the circumferential direction.
  • the present invention relates to a main body unit of an aerosol generation device, an aerosol generation device and a non-combustion suction device, and reliability (connection strength) of a connection state of the unit may be secured by the rotation connection mechanism.
