- the circumferential wall (retention unit 22) of the cartridge accommodation portion 320 is attachable to and detachable from the bottom portion (power unit 21) of the cartridge accommodation portion 320.
- the vertical engagement convex portion 101 is inserted into the engagement concave portion 210 disposed on the same radius and the restriction for the rotation of the cartridge 11 around the axis O is performed. Accordingly, position alignment of the cartridge 11 in the circumferential direction is performed, and electrical conduction of the connection electrodes 213b, 214b (see Fig. 10 ) of the bottom portion 196e of the cartridge 11 and the pin electrode 49 of the power unit 21 is secured.
- the retention unit 22 is assembled to the power unit 21 at first. More specifically, after inserting the horizontal engagement convex portion 102 into the engagement groove 158 in the axial direction, the power unit 21 and the retention unit 22 are relatively rotated around the axis O. Therefore, the power unit 21 and the retention unit 22 are assembled with each other in the first rotation connection portion 301 in a state in which position alignments in the axial direction and the circumferential direction are performed. At the time of detaching the power unit 21 and the retention unit 22, operations reverse to the above-described operations are performed.

- the mouthpiece 23 is assembled with the retention unit 22 by the second rotation connection portion 302. More specifically, the male screw potion 160a of the mouthpiece main body 160 is screwed to the female screw portion 123a of the sleeve 123. Therefore, the first slip prevention member 161 comes in contact with the bottom portion 191c of the cartridge 11.
- the first slip prevention member 161 is elastically deformed such that the cartridge 11 is held in the retaining in the retention unit 22 in a state in which the cartridge 11 is pressed toward the power unit 21 side in the axial direction. A movement of the cartridge 11 with respect to the power unit 21 in the circumferential direction is restricted by the vertical engagement convex portions 101a-101c. Accordingly, the cartridge 11 is configured to not to rotate following the mouthpiece 23 due to the friction force applied between the first slip prevention member 161 and the cartridge 11.
- Fig. 20 is a view showing the state in which the cartridge 11 climbs over the vertical engagement convex portion 101.
- the first slip prevention member 161 comes in contact with the cartridge 11 at least before the screwing is finished. More specifically, as shown in Fig. 21 , at a moment when the male screw portion 160a of the mouthpiece 23 is about to engage with the female screw portion 123a of the retention unit 22, the first slip prevention member is not in contact with the cartridge 11; however, as shown in Fig. 22 , when the male screw portion 160a is screwed with the female screw portion 123a and rotated by a half-rotation or 1, 2 rotations, the first slip prevention member 161 is in contact with the cartridge 11.
- Fig. 22 is a view showing a state in which the mouthpiece 23 and the cartridge 11 are rotated together.
- Fig. 23 is a descriptive view showing the state in which the mouthpiece 23 is finally tightened.
- the mouthpiece 23 may be further screwed.
- the connection electrodes 213b, 214b are pressed by the pin electrodes 49 and the first slip prevention member 161 between the cartridge 11 supported by the power unit 21 and the mouthpiece main body 160 is compressed in the axial direction that the positioning of the cartridge 11 in the axial direction is performed.
- the positioning of the cartridge 11 in the circumferential direction and the axial direction and further the electrically conduction of the cartridge 11 and the power unit 21 are performed by the screwing of the mouthpiece 23.
- a gap between the cartridge 11 and the mouthpiece 23 is sealed by the engagement protrusion 171 of the first slip prevention member 161 being compressed in the axial direction.
- the liquid aerosol source is filled in the liquid storage room 202 of the tank 191, and then the gasket 192 and the mesh body 193 are inserted from the opening portion 191a of the tank 191 in this sequence.
- the surface 192b of the gasket 192 is in contact with the end surface 201a of the convex portion 201 of the tank 191.
- the surface 193b of the mesh body 193 is caused to overlap the other surface 192d of the gasket 192.
- the mesh body 193 itself is soft; however, the orientation the mesh body 193 is maintained by the gasket 192 and the poisoning thereof is performed by the gasket 192.
- the heater holder 196 is assembled to the opening portion 191a of the tank 191. More specifically, the engagement piece 206 side of the heater holder 196 is directed to face the opening portion 191a side of the tank 191 and the heater holder 196 is inserted into the opening portion 191a of the tank 191. At this time, positions of the engagement hole 198 and the guide concave portion 198a formed in the circumferential wall 191b of the tank 191 and a position of the engagement piece 206 of the heater holder 196 are aligned.
- the forces causing the engagement pieces 206 to be elastically deformed are balanced such that it is easy for the heater holder 196 to be inserted into the opening portion 191a of the tank 191.
- the bottom surface 224a of the concave portion 224 of the atomization container 195 is in contact with the internal surface at the internal side of the engagement piece 206 in the radial direction. Accordingly, when the engagement piece 206 is elastically deformed inwardly in the radial direction, the concave portion 224 of the atomization container 195 is slightly deformed inwardly in the radial direction.
- the engagement claw 207 moves along the guide concave portion 198a. Then, the engagement claw 207 climbs over a terminal end of the guide concave portion 198a (end portion at the engagement hole 198 side of the tank 191), and further the engagement claw 207 is inserted into the engagement hole 198 of the tank 191 by a restoring force of the engagement piece 206 and a restoring force of the concave portion 224 of the atomization container 195. Accordingly, the heater holder 196 is fixed to the tank 191 and the assembly of the cartridge 11 is finished.
- the air in the retention unit 22 is suctioned and tie pressure inside the retention unit 22 becomes negative.
- the air in the pressure change room S1 is suctioned through the inside of the atomization container 195 (inside the atomization room M) of the cartridge 11, the buffer space S3, and the communication port 51 such that it also becomes the negative pressure inside the pressure change room S1. More specifically, the air in the pressure change room S1 flows into the buffer space S3 through the communication port 51 and then flows into the heater holder 196 through the second air-suction hole 216.
- the air flowing into the heater holder 196 passes through the flow passage tube 197 through the ventilation passage 226 and the atomization container 195 and then enters the mouth of the user through the mouthpiece 23.
- the pressure sensor 53 outputs a start-up signal to the controller when the pressure sensor 53 detects that the pressure inside the pressure change room S1 is less than a predetermined value, for example.
- the controller receiving the start-up signal causes the heater 194 of the cartridge 11 to be electrified. Since it becomes the negative pressure inside the retention unit 22, fresh air is introduced in the retention unit 22 through the ventilation hole 131. Furthermore, the fresh air is introduced into the atomization room M of the cartridge 11 (the opening room 203 of the tank 191) through the first air-suction hole 209 formed in the heater holder 196 of the cartridge 11 and the ventilation passage 226 of the atomization container 195.
- the liquid aerosol source stored in the liquid storage room 202 of the tank 191 is absorbed by the mesh body 193 and further absorbed by the wick 204.
- the mesh body 193 and the wick 204 is saturated (exceeding a liquid retention force)
- the liquid accumulation portion 223 is formed on the external circumferential surface of the atomization container 195 positioned at the heater holder 196 side of the mesh body 193. Accordingly, the liquid aerosol source is stored in the liquid accumulation portion 223 and leakage to the heater holder 196 side (the side where the heater 194 is disposed) is prevented.
- a volume (space volume) of the liquid accumulation portion 223 is approximately 53.4 cubic millimeters.
- 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.
