When the user completes suctioning, the outer case is controlled to move along the circumferential direction before the aerosol-forming substrate is pulled out, and the circumferential movement will be transferred to the axial movement, so that the axial movement of the outer case will drive the pressing mechanism to apply a radial pressing force to the aerosol-forming substrate.
Under the radial pressing force, on the one hand, the inner case can move in the circumferential direction with the outer case, and can be rotationally switched from the first position to the second position along the circumferential direction with respect to the aerosol generating device; on the other hand, the outer package of the aerosol generating substrate can rotate with the inner case along the circumferential direction and drive the aerosol-forming substrate and the heating body to be relatively moved in the circumferential direction.

The aerosol-forming substrate can be easily pulled out from the heating body by the user, which is convenient to use and also convenient for users to clean the aerosol generating device. Meanwhile, since the heating body and the aerosol-forming substrate are relatively moved in the circumferential direction and have no relative movement in the axial direction, the heating body have no movement in the axial direction during pulling out the aerosol-forming substrate, such that the stability of the connection between the heating body and the aerosol generating device is maintained and the life of the heating body is extended.

Although the description of the present invention will be described in conjunction with the preferred embodiments, the present invention is not limited thereto. Rather, the present invention is described in conjunction with the embodiments so as to cover other possible alternatives or modifications developed based on claims of the present invention. In order to provide a thorough understanding of the present invention, many specific details are included in the following description. In addition, some of specific details are omitted in the description in order to avoid confusing or obscuring key points of the present invention. It should be noted that in the case of no conflict, the embodiment of the invention and the features in the embodiments can be combined with each other.
Referring to
When a user is suctioning, the aerosol-forming substrate is placed in an inner chamber 11a of the inner case 11, and the heating body 23 is inserted into the aerosol-forming substrate. At this time, the aerosol-forming substrate is in contact with the heating body 23, and the heating body 23 is controlled to heat the aerosol-forming substrate to generate an aerosol for the user to suction. When the user finishes suctioning, the outer case 14 is controlled to move along the circumferential direction before the aerosol-forming substrate is pulled out, and the circumferential movement will be transferred to the axial movement, so that the axial movement of the outer case 14 will drive the pressing mechanism 30 to apply a radial pressing force to the aerosol-forming substrate.
Under the radial pressing force, on the one hand, the inner case 11 can move in the circumferential direction with the outer case 14, and can be rotationally switched from the first position to the second position along the circumferential direction with respect to the aerosol generating device 1; on the other hand, the outer package of the aerosol-forming substrate can rotate with the inner case 11 along the circumferential direction, and drive the aerosol-forming substrate and the heating body 23 to be relatively moved in the circumferential direction. The aerosol-forming substrate cannot be easily separated from the outer package, preventing the aerosol-forming substrate from not rotating synchronously while the outer package of the aerosol-forming substrate is rotating synchronously with the inner case 11 along the circumferential direction. After the aerosol-forming substrate is rotated by a sufficient distance along the circumferential direction in synchronization with the inner case 11, that is, after the aerosol-forming substrate is moved by a sufficient distance along the circumferential direction with respect to the heating body 23, and when the aerosol-forming substrate is pulled out from the heating body 23 along the axial direction, the aerosol-forming substrate remaining on the heating body 23 will be less, which is more conducive for users to clean the aerosol generating device 1.
In summary, the aerosol-forming substrate being adhered to the heating body 23 is released from the heating body 23 during the relative movement in circumferential direction between the aerosol-forming substrate and the heating body 23. The aerosol-forming substrate can be easily pulled out from the heating body 23 by the user, which is convenient to use and also convenient for users to clean the aerosol generating device. Meanwhile, since the heating body 23 and the aerosol-forming substrate are relatively moved in the circumferential direction and have no relatively movement in the axial direction, the heating body 23 has no movement in the axial direction during pulling out the aerosol-forming substrate, such that the stability of the connection between the heating body 23 and the aerosol generating device is maintained, and the service life of the heating body 23 is extended.
In the embodiment of the present invention, the inner case 11 is rotationally switched from the first position to the second position along the circumferential direction (shown as the z-direction in
The aerosol-forming substrate has a first axial position with respect to the heating body 23 in the first position; the aerosol-forming substrate has a second axial position with respect to the heating body 23 in the second position, and the first axial position is the same as the second axial position. That is, both in the first position and in the second position, the aerosol-forming substrate is in contact with the heating body 23 without relative movement in the axial direction. Preferably, the aerosol-forming substrate and the heating body 23 have no relative movement in the axial direction during switching from the first position to the second position.
In other embodiments, the first axial position may not be the same as the second axial position. During the rotation of the inner case with respect to the aerosol generating device, the aerosol-forming substrate is in contact with the heating body, and the heating body and the aerosol-forming substrate not only move in the circumferential direction but also move in the axial direction; just the aerosol-forming substrate and the heating body are relatively movable in the circumferential direction and the aerosol-forming substrate is in contact with the heating body during switching from the first position to the second position.
In addition, in the embodiment, during switching from the first position to the second position, the inner case 11 rotates along the circumferential direction, and the heating body 23 remains stationary; in other embodiments, the heating body may rotate along the circumferential direction, and the inner case may remain stationary. Just in the second position, the aerosol-forming substrate and the heating body are relatively moved in the circumferential direction. When the heating body 23 rotates along the circumferential direction, the heating body 23 may rotate synchronously with the aerosol generating device 1 at which the heating body 23 is located, or alternatively, the heating body 23 also may rotate while the aerosol generating device 1 at which the heating body 23 is located may remain stationary.
Additionally, a specific type of the aerosol-forming substrate of the present invention is not limited, as long as it can generate an aerosol for the user to suction after being heated by the heating body 23. The aerosol-forming substrate can be heated but not burned in the process of heating the aerosol-forming substrate by the heating body 23. For example, in the embodiment, the aerosol-forming substrate is a solid aerosol-forming substrate containing a tobacco component, and the aerosol-forming substrate is wrapped by an outer package (for example, an aluminum foil layer).
In addition, a specific shape of the heating body 23 is not limited. In the embodiment, the heating body 23 has a columnar shape with a circular cross section. In other embodiments, the heating body 23 may have a quadrilateral, triangular or polygonal cross section. As the number of sides of the cross section of the heating body 23 increases, the aerosol-forming substrate is more easily released from the heating body 23 during the relative movement in circumferential direction between the heating body 23 and the aerosol-forming substrate. When the aerosol-forming substrate is pulled out from the heating body 23, the amount of aerosol-forming substrate remaining on the heating body 23 is less, which is more advantageous for the user to clean the aerosol generating device 1.
A specific material of the heating body 23 is not limited, as long as it can generate heat after being energized, so as to heat the aerosol-forming substrate to generate an aerosol. For example, in the embodiment, the material of the heating body 23 comprises ceramic.
Additionally, in the embodiment, while the inner case 11 rotates synchronously from the first position to the second position along the circumferential direction, the inner case 11 is rotatable along the circumferential direction in synchronization with the outer case 14. In other embodiments, the outer case may not rotate synchronously with the inner case, as long as the aerosol-forming substrate and the heating body are relatively movable in the circumferential direction, or alternatively in the process of the circumferential rotation of the outer case, at least part of the process is that the inner shell rotates synchronously with the outer shell. In the embodiment, the aerosol-forming substrate is subjected to a radial pressing force during the process from the first position to the second position.
Referring to
In the present embodiment, the convex component 141 extends along the axial direction. However, the extending direction of the convex component is not limited, as long as the inner case is rotatable along the circumferential direction in synchronization with the outer case after the convex component is disposed in the first groove. In addition, the matching form between the inner case and the outer case is not limited to using the convex component and the first groove. Other matching forms may also be used as long as the inner case can rotate synchronously with the outer case along the circumferential direction.
Specifically, referring to
As shown in
When the user is suctioning, the aerosol-forming substrate is placed in the inner chamber 11a of the inner case 11, and the heating body 23 is inserted into the aerosol-forming substrate. At this time, the first convex portions 143 fit with the second concave portions 22 and the second convex portions 21 fit with the first concave portions 144. When the user finishes suctioning, the outer case 14 is controlled to move along the circumferential direction before the aerosol-forming substrate is pulled out, so that the first convex portions 143 and the first concave portions 144 move in the circumferential direction. During this process, the highest points of the first convex portions 143 will be separated from the lowest points of the second concave portions 22, and the highest points of the second convex portions 21 will be separated from the lowest points of the first concave portions 144; the first convex portions 143 and the first concave portions 144 will move along the surface of the second convex portions 21 and the second concave portions 22, and then gaps occur in the axial direction between the first convex portions 143 and the second concave portions 22, as well as between the second convex portions 21 and the first concave portions 144. So, the circumferential movement of the outer case 14 will be transferred to movement along an axial direction.
While the first convex portions 143 move from the lowest points of the second concave portions 22 to the highest points of the second convex portions 21, the outer case 14 will move away from the second end in the axial direction. While the first convex portions 143 move from the highest points of the second convex portions 21 to the lowest points of the second concave portions 22, the outer case 14 will move towards the second end in the axial direction. Equivalently, the circumferential movement of the outer case 14 will be transformed into upwards and downwards reciprocating movement of the outer case 14 in the axial direction. When the first convex parts 143 has been fit with the second concave portions 22 again, the second convex parts 21 has been fit with the first concave parts 144 again, no gap exists between the first convex parts 143 and the second concave portions 22, and no gap exists between the second convex parts 21 and the first concave parts 144, the outer case 14 will not move in the axial direction. The outer case 14 is rotated sequentially to proceed with the reciprocating movement in the axial direction, so that the radial pressing force can be fully applied to the aerosol-forming substrate by the pressing mechanism 30, and it is convenient for the aerosol-forming substrate and the heating body 23 to produce relative movement in the circumferential direction.
In other embodiments, one of the first end and the second end comprises the first convex portion and the other comprises the second concave portion. The first convex portion matches with the second concave portion. For example, the first end comprises the first convex portion, and the second end comprises the second concave portion, wherein the shape of the first convex portion of the first end matches with the shape of the second concave portion of the second end, and the first convex portion cooperates with the second concave portion. In addition, the portion of the first end apart from the first convex portion and the portion of the second end apart from the second concave portion are flat-surface portions that can match with each other. This matching form of the first end and the second end can also be used to achieve the purpose of moving the outer case along the circumferential direction and transferring the circumferential movement to the axial movement.
In the embodiment, the circumferential movement of the outer case 14 is transferred to the axial movement by matching the first convex parts 143 with the second concave parts 22 and matching the second convex parts 21 with the first concave parts 144. Other matching forms may also be used, as long as the circumferential movement can be transferred to the axial movement. For example, in other embodiments, the outer case is screwed with the aerosol generating device, which is equivalent to that one of the outer case and the aerosol generating device is provided with an external thread on its outer circumferential surface, the other is provided with an internal thread on its inner circumferential surface, so that the outer case can be screwed with the aerosol generating device. The circumferential movement is transferred to the axial movement by rotating the outer case.
Or alternatively in other embodiments, the outer surface of the inner case is provided with a spiral groove extending along the axial direction, and the inner surface of the outer case is provided with a convex part, wherein the convex part is disposed in the spiral groove and is slidable within the spiral groove. When the outer case moves in the circumferential direction, the convex part will slide in the spiral groove, so that the circumferential movement of the outer case can be transferred to axial movement.
Referring to
In the embodiment, the portion between the first end 31 and the second end 32 is used for applying the radial pressing force to the aerosol-forming substrate; a convex portion 33 is provided between the first end 31 and the second end 32, and the convex portion 33 protrudes from the first through-hole 12 toward the inner wall of the outer case 14.
When the outer case 14 moves in the axial direction, the inner wall of the outer case 14 will press the convex part 33. Since the first end 31 is connected fixedly with the inner case 11 and the second end 32 is connected flexibly with the inner case 11, the pressed convex part 33 will drive the portion between the first end 31 and the second end 32 to move towards the aerosol-forming substrate along the radial direction after being squeezed, so as to apply the radial pressing force to the aerosol-forming substrate.
In addition, after the aerosol-forming substrate has been suctioned, if the smoking product is pulled out without operating the pressing mechanism 30, the aerosol-forming substrate will be separated from the outer package of the smoking product and stick to the heating body 23, because the friction force between the aerosol-forming substrate of the smoking product and the outer package is smaller than the adhesive force between the aerosol-forming substrate and the heating body. In this case, the convex part 33 can be pressed to drive the portion between the first end 31 and the second end 32 to move towards the aerosol-forming substrate along the radial direction, so as to apply the radial pressing force to the aerosol-forming substrate. As a result, the aerosol-forming substrate will be crushed, which is convenient for separating the aerosol-forming substrate from the heating body 23 to clean the heating body 23.
The inner wall of the outer case 14 may have inner diameters with a larger size on the top and a smaller size on the bottom. The convex part 33 is in contact with the portion of the inner wall of the outer case 14 with a larger inner diameter at the initial state, and the convex portion 33 is in contact with the portion of the inner wall of the outer case 14 with a smaller inner diameter when the outer case 14 moves in the axial direction, so that the inner wall of the outer case 14 will press the convex part 33. The inner wall of the outer case 14 is not limited to a specific shape, as long as the inner wall of the outer case 14 can press the convex part 33 so that the pressing mechanism 30 can apply the radial pressing force to the aerosol-forming substrate when the outer case 14 moves in the axial direction.
Referring to
In other embodiments, the portion between the second end and the convex part is provided with the curved portion mentioned above, and the portion between the first end and the convex part is in a shape of a bar, without being curved. Or alternatively, the portion between the first end and the convex part is provided with the curved portion mentioned above, and the portion between the second end and the convex part is also provided with the curved portion mentioned above. Or alternatively, the portion between the first end and the convex part is in a shape of a bar, without being curved, and the portion between the second end and the convex part is also in a shape of a bar, without being curved.
In the present embodiment, the convex part 33 is abutted against the inner wall of the outer case 14. The convex part 33 is pressed immediately when the outer case 14 moves in the axial direction, so the aerosol-forming substrate is subjected to the radial pressing force immediately. In other embodiments, the convex part is not abutted against the inner wall of the outer case. Additionally, when the convex part 33 is abutted against the inner wall of the outer case 14, there is an elastic force between the convex part 33 and the inner wall of the outer case 14 along the radial direction. Under the elastic force, the outer case 14 cannot move easily in the axial direction unless an external force is applied to the outer case 14, for example when the user rotates the outer case 14 in the circumferential direction. This is equivalent to that the elastic force has a limiting effect in the axial direction, preventing the outer case 14 from falling off along the axial direction with respect to the inner case 11. In addition, the outer case 14 and the inner case 11 can also be maintained by the elastic force when rotating in the circumferential direction, that is the outer case 14 and the inner case 11 can rotate stably along the circumferential direction.
In other embodiments, there may be no elastic force between the convex part and the inner wall of the outer case at the initial state. At the meantime, there is an elastic force between the convex part 33 and the inner wall of the outer case 14, which helps the outer case 14 press the convex part 33 after the outer case 14 moves in the axial direction, so that the pressing mechanism 30 can further apply the radial pressing force to the aerosol-forming substrate.

The inner wall of the second groove 142 may have inner diameters with a larger size on the top and a smaller size on the bottom. The convex part 33 is in contact with the portion oft the inner wall of the second groove 142 with a larger inner diameter at the initial state, and the convex portion 33 is in contact with the portion oft the inner wall of the second groove 142 with a smaller inner diameter when the outer case 14 moves in the axial direction, so that the second groove 142 will press the convex part 33. The inner wall of the second groove 142 is not limited to a specific shape, as long as the second groove 142 can press the convex part 33 so that the pressing mechanism 30 can apply the radial pressing force to the aerosol-forming substrate when the outer case 14 moves in the axial direction.
In addition, provided with the second groove 142, the inner case 11 and the outer case 14 can also rotate synchronously without the convex component 141 and the first groove 111. For example, the convex part 33 is disposed behind the second groove 142, the convex part 33 will not be separated from the second groove 142 when the outer case 14 moves in the axial direction, and will be driven to move in circumferential direction by the second groove 142. In other embodiments, both the convex component and the first groove can be provided.

In the present embodiment, three pressing mechanisms 30 are provided and spaced apart along the circumferential direction. In other embodiments, other amount of the pressing mechanism may be selected. After increasing the contact area, a plurality of the pressing mechanisms 30 can be provided and spaced apart along the circumferential direction so that the pressure can be uniformly distributed on the aerosol-forming substrate, which is advantageous for the aerosol-forming substrate to move synchronously with the inner case 11 along the circumferential direction.
In other embodiments, the portion between the first end and the second end facing the aerosol-forming substrate is provided with a convex part (not shown in figures). The convex part can be used for clamping the aerosol-forming substrate and applying the radial pressing force to the aerosol-forming substrate.

In the embodiment, the outer case 14 is detachably connected to the inner case 11. When the heating body 23 needs cleaning, the outer case 14 is moved along the axial direction with respect to the inner case 11, and the force applied to the outer case 14 can overcome the elastic force present between the convex part 33 and the outer case 14, making the outer case 14 separate from the inner case 11. After the outer case 14 has been dismantled, the second through-hole 13 is exposed, so that a brush (not shown in figures) can be used to clean the heating body 23.

The plane of the second surface 45 is set at an acute angle with the plane of the first surface 44. In the embodiment, the acute angle ranges from 30 degrees to 60 degrees, including 30 degrees and 60 degrees, and it may also be 43.5 degrees. Within this range of the angle, it is advantageous for the debris in the third through-hole 41 to flow out from the inclined hole 42.
