1 and 2 show cross-sectional views of an aerosol generating device 10 according to an embodiment of the present invention. The aerosol generating device 10 includes a casing 12, which includes a first casing 14 and a second casing 16. The second casing 16 is slidable relative to the first casing 14 between a compressed position shown in FIG. 2 and an expanded position shown in FIG. 1. The second casing 16 can also be separated from the first casing 14.

The aerosol generating device 10 also includes a controller 18 and a power supply 20 located in the first casing 14, and a heater 22 extending from one end of the first casing 14. The power supply 20 is a power supply including a rechargeable battery. The heater 22 is An electric heater including a resistive heating element 24. During use, the controller 18 supplies power from the power supply 20 to the resistive heating element 24 to resistively heat the heater 22.

A sensor 26 and a first magnet 28 are located on the first housing 14 near the heater 22. The sensor 26 is an optical sensor. The optical sensor includes a light transmitter and a light receiver. The light transmitter is an infrared light emitting diode, and the light receiver is a photoelectric diode. The photodiode is sensitive to infrared light emitted from the infrared light emitting diode. An optical window 30 covers the sensor 26, wherein the optical window is transparent to infrared light transmitted from the infrared light emitting diode.

The second casing 16 defines a cavity 32 for receiving an aerosol-generating object and an opening 34 located in the cavity 32. When the second casing 16 is attached to the first casing 14, the heater 22 extends into the cavity 32 via a heater opening 36 defined by the second casing 16. An air inlet 38 is formed by a gap between the first casing 14 and the second casing 16. The air inlet 38 is in fluid communication with the cavity 32 through an airflow opening 40 defined by the second casing 16.

When the aerosol-generating object is received in the cavity 32, the aerosol-generating object and the aerosol-generating device 10 together form an aerosol-generating system. During use, the heater 22 heats the aerosol-generating object received in the cavity 32 to generate an aerosol. When a user draws an aerosol-generating object, air is drawn into the aerosol-generating device 10 through the air inlet 38 and passes through the airflow opening 40 Into the cavity 32. Air then flows through the aerosol-generating object to deliver the generated aerosol to the user.

The aerosol generating device 10 also includes a cover element 42 including a cover portion 44 covering an end wall 46 of the second casing 16 and a shaft portion extending through the end wall 46. 48. The cover element 42 is rotatable between a closed position in which the cover portion 44 covers the opening 34 and an open position in which the cover portion 44 does not cover the opening 34. The closed position is shown in FIG. 2 and the open position is shown in FIG. 1. 3 to 5 schematically illustrate rotation of the cover element 42 from the closed position (FIG. 3) to the open position (FIG. 5).

A mechanical linkage device 50 is located in the second housing 16. The mechanical linkage device is configured to interact with the shaft portion 48 of the cover element 42. FIG. 6 shows an exploded view of the mechanical linkage device 50.

The mechanical linkage device 50 includes a base 152 attached to the second casing 16 by screws 54. The second magnet 56 is mounted on the base 152 and is configured to interact with the first magnet 28 on the first housing 14. In particular, the first and second magnets 28, 56 are magnetically attracted to each other to help attach the second housing 16 and the first housing 14.

A locking mechanism 158 and a closing mechanism 159 are also mounted on the base 152 and include a shaft sleeve 160, a cam 162, a cam follower 164, a cam follower biasing spring 165, a torsion spring 166, a A release pin 168 and a release pin biasing spring 169.

The cam 162 is connected to one end of the shaft portion 48 of the cover member 42 by a tight fit. Therefore, when the cover element 42 is closed When rotating between the closed position and the open position, the cam 162 also rotates. The shaft sleeve 160 and the torsion spring 166 are positioned coaxially around the shaft portion 48 of the cover element 42.

The cam follower 164 is slidably received in the base 152 and engages the first cam surface 163 formed on the cam 162. Therefore, when the cam 162 rotates during the rotation of the cover member 42, the cam follower 164 moves up and down inside the base 152. An indicator element 74 containing an optically reflective aluminum layer is located on the bottom surface of the cam follower 164. When the cam follower 164 moves up and down in the base 152, the sensor 26 senses a change in the distance between the sensor 26 and the indicator element 74. Based on the sensing distance between the sensor 26 and the indicator element 74, the sensor 26 provides a signal to the controller 18 indicating that the cover element 42 is in a closed position or an open position.

If the signal from the sensor 26 indicates that the cover element 42 is in the closed position, it is assumed that the aerosol-generating object is not received in the cavity 32, and the controller 18 will not be removed from the power supply 20 The heater 22 is supplied with electricity for heating the aerosol-generating object.

If the signal from the sensor 26 indicates that the cover element 42 is in the open position, the aerosol-generating article can be received in the cavity 32, and the controller 18 can supply power to the power supply from the power supply 20 The heater 22 is used to heat the aerosol-generating object.

If the sensor 26 cannot detect the indicator element 74, it is assumed that the second casing 16 is separated from the first casing 14. In this case, the sensor 26 provides instructions for the second housing 16 and The first housing 14 is separated from the signal to the controller 18, and the controller 18 will prevent power from being supplied to the heater 22.

The operation of the locking mechanism 158 and the closing mechanism 159 will now be described with reference to FIGS. 7 to 18.

Figure 7 shows the cover element 42 in a closed position. When the cover element 42 is in the closed position, the cam follower 164 is biased to a lowered position by the cam follower biasing spring 165, and the release pin 168 is biased by the first housing 14. Keep it in the raised position, as shown in Figure 8.

When the cover element 42 rotates to the open position, the rotation of the cam 162 causes the cam follower 164 to rise to the raised position against the force of the cam follower biasing spring 165 and loads the torsion spring 166 . As shown in FIG. 10, the release pin 168 remains in its raised position.

When the cover element 42 reaches the open position, the cam follower 164 is received in a detent 171 defined by the first cam surface 163 of the cam 162, as shown in FIG. 11. When the cam follower 164 is received in the detent 171, the torsion spring 166 cannot rotate the cam 162 and the cover element 42 back to the closed position. The release pin 168 remains in its raised position, as shown in FIG. 12.

When the second housing 16 is moved away from the first housing 14, the release pin biasing spring 169 pushes the release pin 168 into a lowered position, as shown in FIGS. 13 and 14. During the movement of the release pin 168 to its lowered position, a protrusion 173 on the release pin 168 engages a second cam surface 175 defined by the base 152, which rotates the release pin 168 to move the protrusion The portion 173 is located below the cam follower 164.

When the second casing 16 is moved toward the first casing 14, the first casing 14 pushes the release pin 168 upward against the force of the release pin biasing spring 169. When the release pin 168 moves upward, the projection 173 on the release pin 168 engages the cam follower 164 and pushes the cam follower 164 to its raised position, as shown in FIGS. 15 and 16. When the cam follower 164 is pushed to its raised position, the cam follower 164 is disengaged from the detent 171 defined by the first cam surface 163 of the cam 162.

When the cam follower 164 is disengaged from the detent 171 defined by the first cam surface 163 of the cam 162, the torsion spring 166 rotates the cam 162 and returns the cover member 42 to the closed position, as shown in FIG. 17 Show. At the same time, the first housing 14 continues to push the release pin 168 upward, and the convex portion 173 on the release pin 168 engages a third cam surface 177 defined by the second housing 16. The third cam surface 177 rotates the convex portion 173 away from the cam follower 164, so that the release pin 168 is disengaged from the cam follower 164, as shown in FIG. 18. At this point, the locking mechanism 158 and the closing mechanism 159 have returned to the initial configuration shown in FIGS. 7 and 8.

FIG. 19 shows an exploded view of an alternative configuration of the mechanical linkage 50.

The alternative mechanical linkage device includes a base 252 connected to the second housing 16 by screws 54. The second magnet 56 is mounted on the base 252 and is configured to interact with the first magnet 28 on the first housing 14. In particular, the first and second magnets 28, 56 are magnetically attracted to each other to help attach the second housing 16 And the first case 14.

A locking mechanism 258 and a closing mechanism 259 are also mounted on the base 252 and include a washer 260, a first gear 262, a gear cam follower 264, a cam follower bias spring 265, a release Element 268 and a release element bias spring 269.

The washer 260 is formed of a low-friction material to facilitate rotation of the first gear 262 on the base 252. The first gear 262 is closely connected to one end of the shaft portion 48 of the cover member 42. Therefore, when the cover element 42 rotates between the closed position and the open position, the first gear 262 also rotates.

The gear cam follower 264 is slidably received in the base 252 and engages the first gear 262 and a first cam surface 263 formed by the base 252. Therefore, when the first gear 262 is rotated during the rotation of the cover member 42, the gear cam follower 264 moves up and down inside the base 252. An indicator element 74 containing an optically reflective aluminum layer is located on the bottom surface of the gear cam follower 264. When the gear cam follower 264 moves up and down in the base 252, the sensor 26 senses a change in the distance between the sensor 26 and the indicator element 74. Based on the sensing distance between the sensor 26 and the indicator element 74, the sensor 26 provides a signal to the controller 18 indicating whether the cover element 42 is in a closed position or an open position.

If the signal from the sensor 26 indicates that the cover element 42 is in the closed position, it is assumed that the aerosol-generating object is not received in the cavity 32, and the controller 18 will not be supplied from the power source. The reactor 20 supplies power to the heater 22 for heating the aerosol-generating object.

If the signal from the sensor 26 indicates that the cover element 42 is in the open position, the aerosol-generating article is acceptable in the cavity 32, and the controller 18 can supply power to the heating from the power supply 20 The device 22 is used for heating the aerosol-generating object.

If the indicator element 74 cannot be detected by the sensor 26, it is assumed that the second casing 16 has been separated from the first casing 14. In this case, the sensor 26 provides a signal indicating that the second casing 16 is separated from the first casing 14 to the controller 18, and the controller 18 will prevent power from being supplied to the heater 22 .

The operation of the latch mechanism 258 and the closing mechanism 259 will now be described with reference to FIGS. 20 to 29.

Figure 20 shows the cover element 42 in a closed position. When the cover element 42 is in the closed position, the gear cam follower 264 is biased to a lowered position by the cam follower bias spring 265, and the release element 268 is held in the raised position by the first housing 14 High position, as shown in Figure 21. In the raised position, an inner rib 290 on the release element 268 engages an outer rib 292 on the gear cam follower 264, as shown in FIGS. 28 and 29.

When the cover element 42 is rotated to the open position, the rotation of the first gear 262 causes the gear cam follower 264 to rotate, which causes the release element 268 to rotate. During the rotation of the gear cam follower 264, the first cam surface 263 lifts the gear cam follower 264 to a raised position against the force of the cam follower biasing spring 265, as shown in FIG. 22 . When the cover element 42 reaches the open position, the gear is convex The wheel follower 264 is received in a detent 271 defined by the first cam surface 263, as shown in FIG. When the gear cam follower 264 is received in the detent 271, the cover element 42 cannot rotate back to the closed position.

When the second casing 16 moves away from the first casing 14, the release element biasing spring 269 pushes the release element 268 to a lowered position, which releases the inner rib 290 on the release element 268 from the The outer rib 292 on the gear cam follower 264. During the movement of the release element 268 to its lowered position, a first protrusion 273 on the release element 268 engages a second cam surface 275 defined by the base 252, which rotates the release element 268 to a second protrusion The portion 280 is located below a third cam surface 282 defined by the base 252, as shown in FIGS. 24 and 25.

When the second casing 16 is moved toward the first casing 14, the first casing 14 pushes the release element 268 upward against the force of the release element biasing spring 269, as shown in FIG. 26. . When the release member 268 moves upward, the inner rib 290 on the release member 268 engages the outer rib 292 on the gear cam follower 264 and releases the gear cam follower 264 from the detent 271. At the same time, the second convex portion 280 on the release member 268 engages the third cam surface 282, as shown in FIG. 27, which enables the release member 268, the gear cam follower 264, and the cover member Rotate back to the initial configuration shown in Figs.

30 and 31 show a further alternative configuration of the mechanical linkage 50.

The further alternative mechanical linkage device includes a base 52 connected to the second casing 16 by screws 54. The second magnet 56 is mounted on the base 52 and is configured to interact with the first magnet 28 on the first housing 14. In particular, the first and second magnets 28, 56 are magnetically attracted to each other to help attach the second housing 16 and the first housing 14.

A biasing mechanism 58 is also installed on the base 52. The biasing mechanism 58 includes a washer 60, a first gear 62, a spring holder 64, a torsion spring 66, a main shaft 68, and a cover 70.

The washer 60 is formed of a low-friction material to facilitate the rotation of the first gear 62 on the base 52. The first gear 62 is tightly connected to one end of a shaft portion 48 connected to the cover element 42. Therefore, when the cover element 42 rotates between the closed position and the open position, the first gear 62 also rotates.

A second gear 72 is formed on the outer surface of the spring bracket 64 to engage the first gear 62. The spring bracket 64 is rotatably received in the base 52 and engages a cam surface formed on the base 52. Therefore, when the spring bracket 64 rotates relative to the cam surface, the spring bracket 64 functions as the same cam follower and moves up and down along the main shaft 68. An indicator element 74 containing an optically reflective aluminum layer is located on the bottom surface of the spring holder 64. When the spring bracket 64 moves up and down along the main shaft 68, the sensor 26 senses a change in the distance between the sensor 26 and the indicator element 74. Based on the sensing distance between the sensor 26 and the indicator element 74, the sensor 26 provides an indication whether the cover element 42 is in a closed position or open The position signal is given to the controller 18.

If the signal from the sensor 26 indicates that the cover element 42 is in the closed position, it is assumed that the aerosol-generating object is not received in the cavity 32, and the controller 18 will not be removed from the power supply 20 The heater 22 is supplied with electricity for heating the aerosol-generating object.

If the signal from the sensor 26 indicates that the cover element 42 is in the open position, the aerosol-generating article can be received in the cavity 32, and the controller 18 can supply power to the power supply from the power supply 20 The heater 22 is used to heat the aerosol-generating object.

If the sensor 26 cannot detect the indicator element 74, it is assumed that the second casing 16 is separated from the first casing 14. In this case, the sensor 26 provides a signal indicating that the second casing 16 is separated from the first casing 14 to the controller 18, and the controller 18 will prevent power from being supplied to the heater 22 .

A first end of the torsion spring 66 engages the spring holder 64, and a second end of the torsion spring 66 engages the cover 70. When the user rotates the cover element 42 from the closed position to the open position, the spring holder 64 rotates and loads the tensile spring 66. When the user releases the cover element 42, the load on the tensile spring 66 exerts a rotational force on the spring holder 64, which biases the cover element 42 from the open position to the closed position.
