[0078] Furthermore, as shown in FIG. 2 and FIG. 3, the aerosol generating device 100 includes: a retention mechanism 30 assembled and received within the receiving space 155 for receiving and / or holding the aerosol-generating product 1000; and a heater 40 configured in the shape of an elongated pin or needle, or in the shape of a sheet, etc., wherein the heater 40 extends at least partially from the accommodation space 156 into the accommodation space 155 and / or the holding mechanism 30, so that when the aerosol-generating product 1000 is received and / or held in the holding mechanism 30, the heater 40 can be inserted into and heat the aerosol-generating product 1000; The receiving space 156 also includes a base or flange 50 that surrounds and is coupled to the heater 40 , and the receiving space 156 stabilizes the heater 40 by fastening and retaining the base or flange 50 .

Furthermore, several of the engaging projections 3111 have a tapered shape whose width gradually decreases in the radial direction of the retaining element 31.

[0087] When some of the engaging protrusions 3111 contact a surface area of ​​the aerosol-generating product 1000 , they squeeze or compress the surface area of ​​the aerosol-generating product 1000 , thereby clamping the aerosol-generating product 1000 .

[0088] In addition, a step 3122 and a positioning slot 3121 are provided on the inner surface of the segment 312 of the holding element 31, The retaining mechanism 30 further includes a flexible retaining element 32, which is made of a flexible material such as silica gel or a thermoplastic elastomer, and which is generally annular and has a positioning protrusion 322 extending radially outward; after assembly, the retaining element 32 is accommodated and held within the segment 312 and abuts against the step 3122; at the same time, the positioning protrusion 322 of the retaining element 32 extends into the positioning slot 3121, on the one hand providing positioning during assembly and on the other hand preventing rotation of the retaining element 32 relative to the tubular member 31.

[0089] Furthermore, the retaining element 32 has several clamping protrusions 321 extending radially inwardly, which at least partially clamp the aerosol-generating product 1000 receiving the retaining element 31. In practice, since the clamping protrusions 321 of the retaining element 32 are made of a flexible material, the clamping of the clamping protrusions 321 against the aerosol-generating product 1000 has a larger frictional force and is more stable than the clamping of the engagement protrusions 3111 against the aerosol-generating product 1000. The several clamping protrusions 321 are similarly spaced apart along the circumferential direction.

[0090] Furthermore, the retaining mechanism 30 further includes a cover 33 configured in a thin sheet shape. After assembly, the cover 33 is used to cover the opening of the retaining element 31 to prevent the retaining element 32 from loosening or falling out of the opening of the retaining element 31.

[0091] Further referring to FIG. 2, FIG. 4 to FIG. 6, the driving element 60 and the holding mechanism 30 are connected by a belt transmission method, and the holding mechanism 30 is driven to rotate by the belt transmission. Here, the above-mentioned "belt drive" is a mechanical term, and refers to a mechanical transmission that uses a flexible belt stretched by a pulley to move or transmit power. "Belt transmission" includes a friction belt drive that transmits power by the friction force between the belt and the pulley, and a synchronous belt drive that transmits power by the meshing of the belt with the teeth on the pulley, according to the transmission principle. The "belt transmission" in the embodiment of FIG. 2, FIG. 4 to FIG. 6 is a friction belt drive.

[0092] In the embodiment of FIGS. 2, 4 to 6, it specifically includes a rotatable pulley 62 and a transmission belt 63 .

[0093] The rotatable pulley 62 is located between the inner housing 150 and the first housing 10, and has an axial direction parallel to the axial direction of the holding mechanism 30. The rotating shaft 61 of the driving element 60 protrudes from the opening 158 to the outside of the accommodation space 154 and is inserted into the central hole 621 of the rotatable pulley 62, An annular transmission belt 63, such as a flexible belt, is joined with the rotatable pulley 62 and a part of the circumferential surface of the segment 312 of the holding element 31 to form a belt transmission therebetween, in which in practice the rotatable pulley 62 is the driving pulley in the belt transmission, and the segment 312 of the holding element 31 is the driven pulley in the belt transmission. In a specific practice, a groove 622 surrounding the rotatable pulley 62 is provided on the circumferential surface of the rotatable pulley 62, and a groove 3123 surrounding the segment 312 is provided on the circumferential surface of the segment 312 of the holding element 31, and the annular transmission belt 63 is assembled in the groove 622 and the groove 3123 for transmission. When the rotating shaft 61 of the driving element 60 rotates, the rotatable pulley 62 can move the holding element 31 to rotate around the central axis m.

[0094] Alternatively, in some other variant implementations, power is transmitted between the driving element 60 and the holding element 31 through a transmission mechanism such as a friction wheel transmission, a chain transmission, a gear transmission, a worm gear, a swing link mechanism, a link mechanism, etc., so that the driving element 60 drives the holding element 31 to rotate.

[0095] Alternatively, in some alternative embodiments, the driving element 60 is a cylinder or a hydraulic cylinder, or the like.

[0096] In some other implementations, the rotatable pulley 62 is a gear. Gear transmission is advantageous in terms of precision of control of the rotation angle compared to belt transmission, and gear members of gear transmission may be more difficult to produce and manufacture than pulleys in terms of precision.

[0097] The segments 312 of the retaining element 31 can rotate in response to rotation of the rotation shaft 61 and / or the rotatable pulley 62 of the drive element 60. Furthermore, the rotation of the rotation shaft 61 and / or the rotatable pulley 62 of the drive element 60 can be transmitted to the retaining element 31 via a transmission belt 63.

[0098] In the process in which the organic matter of the aerosol-generating product 1000 is heated by the heater 40, aerosol condensate or solid residue is generated, so that the aerosol-generating product 1000 is tightly attached or adhered to the surface of the heater 40, which is disadvantageous for the user to remove the aerosol-generating product 1000 from the receiving port 111. In this implementation, the heater 40 is needle-shaped extending along the central axis m of the holding element 31. During use, when the driving element 60 drives and rotates the holding element 31, the aerosol-generating product 1000 held in the holding element 31 rotates relative to the heater 40, which eliminates the tight attachment or adhesion of the aerosol-generating product 1000 to the surface of the heater 40, which is advantageous for the user to smoothly remove the aerosol-generating product 1000 from the holding element 31.

[0099] Also, in a more preferred embodiment, after heating is completed, the rotation of the holding element 31 by the driving element 60 may be in one direction, for example, counterclockwise as indicated by the arrow R in FIG. 4, or may be in only the clockwise direction.

[0100] Alternatively, in a further modified embodiment, the rotation of the holding element 31 by the driving element 60 includes two directions, counterclockwise and clockwise. For example, the rotation of the holding element 31 by the driving element 60 rotates at least one revolution counterclockwise and then one revolution clockwise, which is advantageous for breaking up tight adhesion or adhesion of the aerosol-generating product 1000 to the heater 40 surface.

[0101] In a more preferred embodiment, the rotation speed of the holding element 31 driven by the drive element 60 is 0.5 to 5 r / s. The rotation speed of the holding element 31 driven by the drive element 60 is substantially uniform or constant. Alternatively, in some other embodiments, the rotation speed of the holding element 31 driven by the drive element 60 varies, for example, gradually becomes faster or gradually becomes slower.

[0102] In a more preferred embodiment, the segment 311 of the retaining element 31 has an inner diameter of about 7.8 mm and an outer diameter of about 8.6 mm, and the projection height of the engagement projection 3111 relative to the inner surface of the segment 311 is about 1.0 to 2.5 mm. The segment 312 of the retaining element 31 has an inner diameter of about 8.4 mm and an outer diameter of about 9.8 mm.

[0103] The outer diameter of rotatable pulley 62 is approximately 5.0-7.6 mm, smaller than the outer diameter of one or both of segments 311 and / or segments 312 of retaining element 31, which is advantageous in reducing twisting of aerosol-generating product 1000 during rotation.

[0104] Also, in a more preferred embodiment, the ratio of the outside diameter of the rotatable pulley 62 to the outside diameter of the segment 312 serving as the driven pulley is between 0.1 and 10.

[0105] Furthermore, in practice, the above-mentioned holding mechanism 30, particularly the holding element 31, cannot be removed outside the outer housing.

[0106] 7 is a schematic diagram of a driving element 60a and a holding mechanism 30a in an aerosol generating device 100 according to another embodiment. In this embodiment, the holding mechanism 30a is a holding element 31a having a cavity defined therein for receiving and holding the aerosol-generating product 1000, the inner wall of the holding element 31a being provided with a number of engaging projections and flexible clamping elements for clamping the aerosol-generating product 1000; A cover 33a is provided at the upper end of the holding element 31a for covering the flexible clamping element and holding it within the holding element 31a.

[0107] The retaining element 31a further has an elongated extension arm 3121a extending radially outwardly, the extension arm 3121a being provided with an elongated guide hole 3122a, which in the preferred embodiment of FIG. 7 is a slotted hole extending along the length of the extension arm 3121a.

[0108] The driving element 60a is, for example, a motor, and the rotation shaft 61a of the driving element 60a is inserted into the rotatable pulley 62a, which is provided with a guide protrusion 622a arranged offset from the center or rotation shaft 61a, and which extends at least partially into the guide hole 3122a. In this implementation, when the driving element 60a drives the rotatable pulley 62a to rotate, the guide protrusion 622a moves in the guide hole 3122a to move and rotate the holding element 31a.

[0109] In the embodiment, as shown in Fig. 7, the rotation of the holding element 31a by the driving element 60a is performed within a certain angle α as indicated by the arrow R in Fig. 7. The driving element 60a drives the holding element 31a to rotate it around the central axis m. In the preferred embodiment, the angle α of the rotation of the aerosol-generating product 1000 held by the holding element 31a by the driving element 60a is less than 180 degrees, and preferably less than 90 degrees.

[0110] Also, in a more preferred embodiment, the aerosol-generating product 1000 clamped in the holding element 31a is rotated by the driving element 60a alternately in a clockwise and counterclockwise direction.

[0111] 8 and 9 show schematic diagrams of a driving element 60b and a holding mechanism in an aerosol generating device 100 according to another embodiment. a retaining element 31b, the interior of which is used to define a cavity for receiving the aerosol-generating product 1000, and in this embodiment the inner wall is substantially smooth and has no engaging protrusions on the inner wall for clamping the aerosol-generating product 1000; a bracket 71b for receiving and mounting the retaining element 31b, extending in a longitudinal direction and provided with a longitudinal side opening 711b for at least partially exposing the retaining element 31b; a bracket 72b extending substantially perpendicular to the longitudinal direction of the aerosol generating device 100 and abutting and fixed to the upper end of the bracket 71b; an annular element 32b arranged coaxially and aligned with the holding element 31b along the longitudinal direction, supported and held by a bracket 72b, and having on its inner wall a number of engagement projections 321b for clamping the aerosol-generating product 1000; a rotatable pulley 62b connected to a rotating shaft 61b of the driving element 60b, rotatable under the driving of the rotating shaft 61b of the driving element 60b, and attached to a bracket 72b and supported and held by the bracket 72b; and a transmission belt 63b, such as a flexible belt, that transmits between the rotatable pulley 62b and the annular element 32b. The rotatable pulley 62b is a drive pulley of the belt transmission, and the annular element 32b is a driven pulley of the belt transmission. In practice, the annular element 32b rotates about a central axis m of the holding element 31b / annular element 32b while clamping the aerosol-generating product 1000, thereby eliminating adhesion or adhesion to the heater 40b.

[0112] Also, in the embodiment of Figures 8 and 9, a base or flange 50b surrounds the outside of the heater 40b and is coupled thereto, and the aerosol generating device 100 stably mounts the heater 40b by holding the base or flange 50b.

[0113] 8 and 9, the retaining element 31b has a length of about 10-20 mm. The annular element 32b is spaced from the retaining element 31b, with the axial distance d1 between the annular element 32b and the retaining element 31b being about 2-8 mm. The axial extension of the annular element 32b is more than 5 mm, which is advantageous in preventing twisting during rotation of the aerosol-generating product 1000, and preferably the annular element 32b has a length of about 5-10 mm.

[0114] Alternatively, in yet another embodiment shown in Figs. 10-11, the aerosol generating device 100 comprises: a retaining element 31c used to define a cavity for receiving the aerosol-generating product 1000 therein, and in this embodiment, the inner wall of the retaining element 31c is substantially smooth, and the inner wall of the retaining element 31b does not have any engagement projections for clamping the aerosol-generating product 1000; a bracket 71c for receiving and mounting the retaining element 31c, extending in a longitudinal direction and provided with a longitudinal side opening 711c for at least partially exposing the retaining element 31c; a bracket 72c extending substantially perpendicular to the longitudinal direction of the aerosol generating device 100 and abutting and fixed to an upper end of the bracket 71c; an annular element 32c arranged coaxially and aligned with the holding element 31c along the longitudinal direction, supported and held by a bracket 72c, and having on its inner wall a number of engagement projections 321c for clamping the aerosol-generating product 1000; a heater 40c at least partially inserted within the holding element 31c; A base or flange 50c, a base portion 51c surrounding and coupled to the heater 40c for holding the heater 40c; a base or flange 50c including an elongated extension arm 52c extending radially outwardly of the base portion 51c and having an elongated guide hole 521c; and a driving element 60c, such as a motor, with a rotating shaft 61c inserted within a rotatable pulley 62c having an off-center guide protrusion 621c with the guide protrusion 621a extending at least partially within the guide hole 521c. In this implementation, when the driving element 60c drives the rotatable pulley 62c to rotate, the guide protrusion 621c moves within the guide hole 521c to move and rotate the base portion 51c, thereby allowing the heater 40c to rotate relative to the clamped aerosol-generating product 1000 and eliminating any adhesion or adhesion therebetween.

[0115] Alternatively, in some other variant implementations, the base or flange 50c may have only a base portion 51c and is connected to a drive element 60c by a belt transmission and driven by the drive element 60c to rotate the heater 40c relative to the clamped aerosol generating product 1000.

[0116] Also, as shown in the embodiment of Figures 10 to 12, heater 40c is a resistive heater and is connected to circuit board 22 via conductive lead wire 41c, and in this embodiment, conductive lead wire 41c needs to have a length longer than usual to prevent it from being stretched or pulled apart by rotation of heater 40c.

[0117] In this embodiment, the length of the conductive lead wire 41c is more than 25 mm, more preferably more than 35 mm, more preferably more than 45 mm. In this embodiment, the direction of rotation of the heater 40c by driving the driving element 60c is not constant in order to prevent the conductive lead wire 41c from being entangled or cut when the direction is constant. Therefore, in this embodiment, the rotation of the heater 40c by driving the driving element 60c is alternately performed counterclockwise and clockwise. In addition, the angle of rotation of the heater 40c by driving the driving element 60c is preferably less than 90 degrees.

[0118] Alternatively, in some other variant implementations, the driving element has a first rotation axis at a first end in the longitudinal direction and a second rotation axis at a second end in the longitudinal direction, where the first rotation axis of the driving element is used to drive the aerosol-generating product 1000 held by the holding element to rotate about the central axis of the cavity, and the second rotation axis of the driving element is used to drive the base or flange to rotate and further move the heater to rotate about the central axis of the cavity. In implementations, the driving element can drive the relative rotation of the aerosol-generating product 1000 and the heater via the first rotation axis and / or the second rotation axis.

[0119] 13 to 15 show schematic diagrams of a driving element 60d and a holding mechanism 30d of an aerosol generating device 100 according to yet another modified embodiment. In this embodiment, the holding mechanism 30d is a retaining element 31d having a cavity defined therein for receiving and holding the aerosol-generating product 1000, the retaining element 31d having a segment 311d and a segment 312d, and having several longitudinally extending engagement projections 3111d within the segment 311d for clamping or holding the aerosol-generating product 1000; a flexible holding element 32d having an annular shape and a clamping protrusion 321 for clamping the aerosol-generating product 1000; and a cover 33d for covering and fastening the holding element 32d at the upper end of the holding element 31d.

[0120] The heater 40d is configured in the shape of a sheet or blade extending at least partially within the retaining element 31d, and in the specific implementation shown in FIG. 15, the heater 40d has a length of about 19 mm, a width of 5 mm and a thickness of 0.5 mm; The driving element 60d has a telescopic shaft 61d that can freely expand and contract. In some implementations, the driving element 60d is a typical telescopic motor, and in other implementations, the telescopic shaft 61d of the driving element 60d is a typical rotary motor with a screw nut or steering bearing added to the rotary shaft, thereby converting circumferential rotation into telescopic movement.

[0121] The driving element 60d is used to drive the retention mechanism 30d to move along the width direction of the heater 40d to remove adhesion or adhesion of the aerosol-generating product 1000 to the surface of the heater 40d. For example, Fig. 13 shows a schematic diagram of one relative position of the retention mechanism 30d and the heater 40d, in which the heater 40d is substantially aligned with the central axis of the retention mechanism 30d. Fig. 14 shows a schematic diagram of the retention mechanism 30d moving to another position, in which the heater 40d is substantially offset from the central axis of the retention mechanism 30d.

[0122] In addition, in this embodiment, the driving element 60d drives the movement of the holding mechanism 30d, the direction of which is alternated toward both sides in the width direction of the heater 40d, and after the movement, it is finally necessary to reset the holding mechanism 30d and return it to the initial position shown in Figure 13.

[0123] In some preferred implementations, during movement of the retaining mechanism 30d by actuation of the driving element 60d, the maximum movement distance of the retaining mechanism 30d along the width direction of the heater 40d is less than 3 mm.

[0124] 13 and 14, the heater 40d is immovable, and the driving element 60d drives the holding mechanism 30d to move relative to the heater 40d. Alternatively, in some other modified embodiments, the holding mechanism 30d is fixed and immovable, and the driving element 60d drives the heater 40d to move relative to the holding mechanism 30d.

[0125] Alternatively, Fig. 16 shows a schematic diagram of a driving element 60e and a holding mechanism of an aerosol generating device 100 according to yet another modified embodiment. a holding element 31e for receiving and holding the aerosol-generating product 1000; a heater 40e at least a portion of which extends into and is received within the retaining element 31e, and which has a base or flange 50e surrounding and secured to its exterior for ease of assembly within the aerosol generating device 100; and a drive element 60e for driving a connection arm 62e connected to the holding element 31e, thereby enabling the holding element 31e to move axially relative to the heater 40e.

[0126] Alternatively, in yet another variant implementation, the driving element 60e drives the heater 40e to move relative to the holding element 31e along the axial direction of the holding element 31e.

[0127] In addition, in some implementations, the movement of the retaining element 31e is restricted within the outer housing of the aerosol generating device 100, and the retaining element 31e does not protrude outside the outer housing during movement. Also, a user cannot touch the retaining element 31e to move it. Also, in such implementations, the retaining element 31e is not connected to the outer housing, and the size or length of the outer housing does not change when the retaining element 31e is driven to move in the vertical direction of the outer housing.

[0128] Furthermore, in practice, the heater 40e has a length of approximately 15 to 20 mm, and the distance of the aerosol-generating product 1000 held by the holding element 31e is controlled to approximately 2 to 5 mm, i.e., there is no need to substantially extract or remove the aerosol-generating product 1000 from the aerosol generating device, and there is no need to substantially separate the aerosol-generating product 1000 and the heater 40e.

[0129] In addition, in some implementations, the axial movement of the holding element 31e caused by the driving element 60e is performed back and forth, and after the movement, it is necessary to further reset the holding element 31e to the initial state shown in FIG.

[0130] Also, in practice, a user can only remove the aerosol-generating product 1000 from the outer housing / cavity / retention mechanism by gripping or manipulating the portion of the aerosol-generating product 1000 that is exposed outside the outer housing.

[0131] In one implementation, movement of the aerosol generating product 1000 relative to the heaters 40 / 40a / 40b / 40c / 40d / 40e by actuation of the actuation elements 60 / 60a / 60b / 60c / 60d / 60e is controlled in time by a controller on the circuit board 22.

[0132] For example, Fig. 17 shows a schematic diagram of a heating curve of the aerosol-generating product 1000 within a predetermined time in one embodiment. Also, during heating, the controller of the circuit board 22 controls the heating temperature supplied from the heaters 40 / 40a / 40b / 40c / 40d / 40e to the aerosol-generating product 1000 according to the predetermined heating curve. In some implementations, the heating curve is within a predetermined time, and the predetermined time is set based on the amount of aerosol that can be generated from the aerosol-generating product 1000 and the inhalation time allowed by a user (e.g., 4 min). For example, with respect to the heating curve in Fig. 17, the heating process includes the following steps S1 to S3.

[0133] In the first step S1, the temperature is rapidly increased from room temperature to a first predetermined temperature T1 within t1 hours, and the temperature is preheated, which may be referred to as a preheating step; In the second stage S2, the temperature is lowered from the first predetermined temperature T1 to the second predetermined temperature T2 within the time period t2; In the third stage S3, the heating temperature is substantially maintained at a third predetermined temperature equal to the second predetermined temperature T2 until the end of the time t3, whereby the aerosol-generating product 1000 is stably heated at the second predetermined temperature T2 to generate an aerosol for inhalation, and after inhalation is completed, the heating is stopped and the aerosol-generating product 1000 is allowed to naturally cool. Alternatively, in some other variant implementations, during inhalation in the third stage S3, the third predetermined temperature may be higher or lower than the second predetermined temperature T2.

[0134] Accordingly, in some implementations, the controller controls the driving element 60 / 60a / 60b / 60c / 60d / 60e to drive the aerosol-generating product 1000 to move relative to the heater 40 / 40a / 40b / 40c / 40d / 40e at a certain frequency or number of times or at a predetermined time interval. The adhesion or adhesive strength of the aerosol-generating product 1000 to the heater 40 / 40a / 40b / 40c / 40d / 40e during heating can be reduced or prevented. For example, their relative movement is driven at a time interval of 20 to 180 s. More preferably, it is driven at a time interval of 120 s, 60 s, or 30 s.

[0135] Alternatively, in some other implementations, the controller controls the relative movement between the aerosol-generating product 1000 and the heater 40 / 40a / 40b / 40c / 40d / 40e within a specific time of the heating curve. For example, in one embodiment, in the pre-heating stage (0 to t1 hours) of the first stage S1, the relative movement between the aerosol-generating product 1000 and the heater 40 / 40a / 40b / 40c / 40d / 40e is driven once to reduce adhesion caused by the high temperature of the pre-heating stage, and in the third stage S3 (t2 to t3 hours), the relative movement is driven at least twice. Also, within a predetermined time before the end of the third stage S3, at least one movement is driven, so that the user can immediately remove the aerosol-generating product 1000 when inhalation is finished. Also, in the second stage S2, the relative movement by driving is prohibited or prevented.

[0136] In some preferred embodiments, one of the at least two movements driven in the third stage S3 (times t2 to t3) is performed within a predetermined time before the end of the third stage S3. In some preferred embodiments, the predetermined time before the end of the third stage S3 is 20 s, more preferably 10 s, more preferably 5 s, and more preferably 3 s.

[0137] From the above, by moving the aerosol-generating product 1000 once within a predetermined time immediately before the end time t3 of the heating process, the user can remove the aerosol-generating product 1000 when inhalation ends.

[0138] Furthermore, in practice, of the at least two movements driven in the third stage S3 (times t2 to t3), at least one is performed between time t2 and a predetermined time before the end of the third stage S3, for example, (the time from t2 to t3 minus the predetermined time).

[0139] In practice, the above "one movement" refers to a process in which the rotation shaft of the driving element starts to rotate, driving the holding element and the heater to change from a static state to a dynamic state relative to each other, and the rotation shaft of the driving element stops to rotate, driving the holding element and the heater to change from a dynamic state to a static state again. Alternatively, the "one movement" refers to the holding element and the heater starting to move from a static state relative to each other and then returning to a static state. Of course, during the "one movement", the relative movement of the holding element and the heater is maintained substantially continuously or without interruption.

[0140] In some implementations, the "single movement" may be in a fixed direction, or the "single relative movement" may be alternating or reciprocating in two opposing directions.

[0141] Alternatively, in some implementations, the movement time of a "single movement" is controlled to 1 to 10 s, and more preferably, to 2 to 6 s.

[0142] Alternatively, in some other implementations, the controller controls the relative movement between the aerosol-generating product 1000 and the heater 40 / 40a / 40b / 40c / 40d / 40e after the heating is terminated based on the monitoring. For example, the controller controls to prevent the relative movement before the heating process of the aerosol-generating product 1000 is terminated (e.g., 0 to t3 hours) to avoid affecting the heating. Also, the controller controls to perform the relative movement within a predetermined time (e.g., within 3 s, within 5 s, within 10 s, within 20 s) after the heating is terminated, which is advantageous for the user to remove the aerosol-generating product 1000 after the inhalation is terminated.

[0143] Alternatively, in some other implementations, the controller controls the relative movement to occur just before inhalation ends, for example within 10 s or 20 s before time t3, which is advantageous for the user to remove the aerosol generating product 1000 after inhalation ends.

[0144] In addition, in some other implementations, after the process of heating the aerosol generating product 1000 according to the above-mentioned heating curve for a predetermined time is completed, the holding element and heater that have moved relative to each other can be reset and controlled and driven to return to their initial positions before movement.

[0145] Also, in another embodiment, the control of the relative movement by the controller prevents the user from inhaling the aerosol-generating product 1000. Specifically, the controller determines the user's inhalation by monitoring the drop in temperature caused when the inhaled airflow of the user passes through the heater 40 / 40a / 40b / 40c / 40d / 40e during inhalation, and prevents the relative movement upon monitoring the user's inhalation.

[0146] In another specific embodiment, the controller determines the user's inhalation behavior based on the difference between the power supplied to the heater 40 / 40a / 40b / 40c / 40d / 40e during the inhalation process and the target power that maintains the heating temperature at a predetermined temperature of the heating curve.

[0147] In another variant embodiment, the movement of the aerosol generating product 1000 relative to the heater 40 / 40a / 40b / 40c / 40d / 40e is driven by user control. For example, an input element (not shown) is provided on the exterior housing of the aerosol generating device 100 for a user to operate to form an input signal, and the controller controls the relative movement based on the user's input signal. In some implementations, the input element is selected from a mechanical button, a membrane button, a mechanical switch, a rotary encoder, a dial, a knob, a capacitive touch button, a resistive touch button, a joystick, a slider, a trigger button, a touch screen, and a magnetic switch.

[0148] Example 2 An embodiment of the present application provides an aerosol generating device 100, as shown in Figures 18 to 20, the aerosol generating device 100 includes a first cavity 10A, a heater 40, a circuit board 22, a battery cell 21 and a holding element 31, the battery cell 21 and the heater 40 are all electrically connected to the circuit board 22, and the circuit board 22 includes a controller of the aerosol generating device 100, so that the controller of the aerosol generating device 100 can control the battery cell 21 to supply power to the heater 40. The holding element 31 is formed with a second cavity 51 defined therein, and at the same time, the holding element 31 is accommodated in the first cavity 10A, and the second cavity 51 is used for receiving and holding an aerosol generating product 1000 to be used in combination with the aerosol generating device 100, and the heater 40 extends at least partially into the second cavity 51 so as to be inserted into the aerosol generating product 1000 for heating and generating aerosol. It is easily understood that the battery cell 21 may be a rechargeable battery cell or a non-rechargeable battery cell.

[0149] The aerosol-generating product 1000 preferably employs a tobacco-containing material that releases volatile compounds from the substrate upon heating, or may be a non-tobacco material suitable for electrical heating to generate smoke after heating. The aerosol-generating product 1000 preferably employs a solid substrate, which may include one or more of the following powders, granules, elongated pieces, strips or sheets of vanilla leaf, tobacco leaf, homogenized tobacco, expanded tobacco, or the solid substrate may include additional tobacco or non-tobacco volatile flavor compounds to be released upon heating of the substrate. In this embodiment, the aerosol-generating product 1000 is described employing a cigarette filled with tobacco material therein.

[0150] As shown in Fig. 20, the heater 40 is configured in the shape of a long, thin pin, needle, or sheet so that it can be smoothly inserted into the aerosol-generating product 1000 and heated. In some implementations, the heater 40 is a resistive heating element that generates Joule heat when supplied with a direct current. Alternatively, in some other implementations, the heater 40 is a sensitive heating element made of a sensitive material that can be penetrated by a changing magnetic field to generate heat. Alternatively, in some other implementations, the heater 40 is an infrared heating element that heats the aerosol-generating product 1000 by emitting infrared rays.

[0151] In some embodiments, as shown in Figures 17 and 18, vertically extending ribs 52 are formed on the inner wall of the second cavity 51, and the ribs 52 are multiple and uniformly arranged around the inner wall of the second cavity 51, so that a clamping space is surrounded by the multiple ribs 52, thereby allowing the aerosol-generating product 1000 to be clamped by the multiple ribs 52 and held in the holding element 31 when contained in the second cavity 51.

[0152] 20 and 21, the aerosol generating device 100 further includes a driving pulley 60A and a driving element 60, the driving element 60 includes a rotating shaft 61, the rotating shaft 61 is connected to the driving pulley 60A and rotates the driving pulley 60A by rotating. At the same time, the holding element 31 is provided with a driven pulley 31A that rotates the holding element 31 by rotating, the aerosol-generating product 1000 is clamped by the ribs 52 and held by the holding element 31, and there is sufficient friction between the aerosol-generating product 1000 and the ribs 52, so that when the holding element 31 rotates, the aerosol-generating product 1000 can be moved and rotated synchronously. The drive pulley 60A and the driven pulley 31A are transmitted by gear meshing, so that when the drive element 60 drives and rotates the rotating shaft 61, the rotating shaft 61 moves and rotates the drive pulley 60A, which moves and rotates the driven pulley 31A, which further moves and rotates the aerosol-generating product 1000 relative to the heater 40, and under the effect of this relative rotation, the adhesion of tobacco to the heater 40 in the aerosol-generating product 1000 can be effectively reduced.

[0153] In some embodiments, the driving element 60 is a cylinder or a hydraulic cylinder, etc. In addition, the transmission relationship between the driving pulley 60A and the holding element 31 is not limited to the gear meshing transmission, and in some embodiments, the transmission can be performed by a transmission mechanism such as a chain transmission, a worm gear, a swing link mechanism, a link mechanism, or a belt pulley. In a specific embodiment, for the belt transmission method shown in FIG. 22, the driving pulley 60A and the driven pulley 31A are both belt pulleys, and a transmission belt 61B, which can be a flexible belt, is provided between the driving pulley 60A and the driven pulley 31A, so that the rotation of the driving pulley 60A can move the transmission belt 61B, and the movement of the transmission belt 61B further moves and rotates the driven pulley 31A, thereby realizing the transmission between the driving pulley 60A and the holding element 31.

[0154] It should be noted that in some embodiments, the retaining element 31 may be directly attached to the inside of the aerosol generating device 100, and the retaining element 31 and the aerosol generating device 100 are always connected throughout the entire process of inserting the aerosol generating product 1000 into the retaining element 31 and extracting it from the retaining element 31. In other embodiments, the retaining element 31 may be separate from the aerosol generating device 100, and as shown in FIG. 17, the aerosol generating device 100 includes a first part 80 and a second part 90, in which the retaining element 31 and the drive pulley 60A are all located in the first part 80, while the first cavity 10A, the heater 40, the circuit board 22, the battery cell 21 and the drive element 60 are all located in the second part 90, and the first part 80 may be coupled to or separated from the second part 90. The retaining element 31 is accommodated in the first cavity 10A with a portion exposed from the first part 80 and the first part 80 and the second part 90 being connected, and the user can separate the first part 80 and the second part 90 by operating the first part 80, and at the same time, the retaining element 31 and the second part 90 are also separated, so that the user can extract the aerosol generating product 1000 by operating the first part 80, and in this case, the first part 80 has the same role as a tobacco extractor.

[0155] The separable configuration of the retaining element 31 and the second part 90 allows, on the one hand, the retaining element 31 to be removed from the first cavity 10A, facilitating cleaning of the inner walls of the first cavity 10A, and, on the other hand, the retaining element 31 can also be removed and cleaned separately. However, throughout the entire steps of inserting the aerosol-generating product 1000 into and extracting it from the retaining element 31, the retaining element 31 remains connected to the aerosol-generating device 100.

[0156] In some embodiments, the aerosol generating device 100 does not need to be provided with a driving pulley 60A, and the holding element 31 does not need to be provided with a driven pulley 31A that transmits power to the driving pulley 60A. Instead, the rotating shaft 61 of the driving element 60 can be inserted into the holding element 31, and when the rotating shaft 61 rotates, the holding element 31 can be moved and rotated, which in turn can move and rotate the aerosol generating product 1000. Alternatively, in some embodiments, the aerosol generating product 1000 and the heater 40 can be rotated relatively in the same manner by rotating the heater 40 instead of the holding element 31. For example, the heater 40 is generally provided with a base, and in this case, the rotating shaft 61 of the driving element 60 can be inserted into the base of the heater 40, and the base can be moved and rotated by the rotation of the rotating shaft 61, which in turn can move and rotate the heater 40.

[0157] In some embodiments, still referring to FIG. 21, the retaining element 31 has an open end 54 for allowing the aerosol generating product 1000 to enter the second cavity 51, and a gear 531 on the driven pulley 31A is provided surrounding the open end 54, and by providing the gear 531 at the open end 54 of the retaining element 31, the structural design of other components of the aerosol generating device 100 can be facilitated.

[0158] In some embodiments, the driven pulley 31A and the retaining element 31 are integrally molded to reduce the steps of assembling the aerosol generating device 100 and to further improve the efficiency of assembling the aerosol generating device 100. Of course, in some other embodiments, the driven pulley 31A may be an independent member that is fixed to the retaining element 31 by a fixing device, so that the driven pulley 31A moves and rotates the retaining element 31 when it rotates.

[0159] Continuing to refer to FIG. 17, FIG. 17 shows a schematic diagram of a heating curve within a predetermined time of the aerosol-generating product 100 in the above embodiment. In the operation process of the aerosol generating device 100, the controller on the circuit board 22 controls the heater 40 according to the predetermined heating curve. In some implementations, the heating curve is within a predetermined time, and the predetermined time is set based on the amount of aerosol that can be generated from the aerosol-generating product 1000 and the inhalation time allowed by a user (e.g., 4 min). For example, with respect to the heating curve in FIG. 17, the heating process includes the following steps S1 to S3.

[0160] In a first stage S1, the temperature is rapidly increased from room temperature or an initial temperature to a first predetermined temperature T1 within a time period t1; In the second stage S2, the temperature is lowered from the first predetermined temperature T1 to the second predetermined temperature T2 within the time period t2; In the third stage S3, the heating temperature is substantially maintained at the second predetermined temperature T2 until the end of the time t3, so that the aerosol-generating product 1000 is stably heated at the second predetermined temperature T2 to generate an aerosol for inhalation, and after inhalation is completed, the heating is stopped and the aerosol-generating product 1000 is allowed to cool naturally. The shape of the heating curve is not limited to that shown in Figure 17, and in some other embodiments, the second predetermined temperature T2 during the second stage S2 may be approximately the same as the first predetermined temperature T1 or may be higher than the first predetermined temperature T1.

[0161] It should be explained that the first stage S1 and the second stage S2 may be collectively referred to as a pre-heating stage, and the third stage S3 may be referred to as a puffing stage, and after the completion of the pre-heating stage, the controller on the circuit board 22 controls the feedback element to provide feedback to the user, indicating to the user that the pre-heating is completed and puffing may begin, and the feedback element may be a vibration motor or an indicator light, etc. In the puffing stage, the controller controls the battery cell 21 to supply a small power to the heater 40, so as to substantially maintain the temperature at the second predetermined temperature T2, which is smaller than the power supplied from the battery cell 21 to the heater 40 in the pre-heating stage.

[0162] The pre-heating stage refers to a stage in which the temperature of the aerosol-generating product 1000 is increased to a temperature that generates a sufficient amount of aerosol, and when the pre-heating stage is completed, the solid tobacco inside the aerosol-generating product 1000 may have reached a temperature that releases volatile components contained in the tobacco. In the pre-heating stage, the power supplied to the heater 40 may depend on a first pre-heating temperature set by the controller. In the pre-heating stage, the heater 40 may be caused to reach the first pre-heating temperature by supplying a predetermined power. Here, the first predetermined temperature is not limited to one value and may generally be a temperature range.

[0163] The inhalation phase refers to a phase in which aerosol can be generated by the aerosol generating device 100 at a sufficient rate and can be inhaled by a user. In the inhalation phase, the temperature may be substantially maintained at a second predetermined temperature T2, where the second predetermined temperature is not limited to one value and may generally be a temperature range, and the temperature of the heater 40 may be reduced to a third predetermined temperature T3 by reducing the power supplied to the heater 40, where the third predetermined temperature T3 is less than the second predetermined temperature T2, and the temperature of the heating element may be increased to a fourth predetermined temperature T4 by increasing the power supplied to the heater 40, where the fourth predetermined temperature T4 is greater than the second predetermined temperature T2.

[0164] Based on the aerosol generating device 100 described in the above embodiments, one embodiment of the present application further provides a control method for the aerosol generating device 100, which controls the driving element 60 to drive and rotate the holding element 31 or the heater 40 within a predetermined time, thereby rotating the aerosol generating product 1000 in the holding element 31 and the heater 40 relatively, and reducing the adhesion of tobacco in the aerosol generating product 1000 to the heater 40 through the effect of the relative rotation.

[0165] Specifically, the method includes controlling the drive element 60 to drive one of the holding element 31 or the heater 40 to rotate relative to the other during the preheating stage, and controlling the drive element 60 to stop operation at or before completion of the preheating stage.

[0166] According to the description of the above embodiment, the heating curve of the heater 40 is determined by the controller on the circuit board 22, and the driving element 60 is also electrically connected to the controller, so that the controller can control whether the driving element 60 operates or not only based on the current state of the heater 40.

[0167] Since the pre-heating stage is generally short (within 30S), the heater 40 can be heated to a temperature that releases the volatile components contained in the tobacco in the aerosol-generating product 1000 in a short time, and in this case, the tobacco in the aerosol-generating product 1000 is very easily attached to the heater 40. Therefore, at this stage, the driving element 60 can be controlled to drive one of the holding element 31 or the heater 40 to rotate relative to the other, so that the aerosol-generating product 1000 and the heater 40 can be moved relatively, and the adhesion of the tobacco in the aerosol-generating product 1000 to the heater 40 can be effectively reduced under the action of the relative rotation. Specifically, the driving element 60 can also be controlled to stop operating at or before the completion of the pre-heating stage. On the other hand, since the third stage is the inhalation stage, controlling the driving element 60 to operate at this time is likely to affect the user's inhalation, resulting in a poor user experience.

[0168] Furthermore, tobacco leaves in cigarettes usually contain moisture, which is also called tobacco leaf moisture or tobacco leaf moisture content, and when the tobacco leaves are heated under the action of the moisture, they adhere to the heater 40. However, since the moisture in the tobacco leaves has already evaporated in the preheating stage, the moisture content in the tobacco leaves is very low in the inhalation stage, and in this case, the tobacco leaves are less likely to adhere to the heater 40 even under high temperature conditions, so it is sufficient to control the holding element 31 or the heater 40 to rotate relatively only in the preheating stage. It is understandable that in some other embodiments, in order to sufficiently reduce the adhesion of tobacco in the aerosol-generating product 1000 to the heater 40, the holding element 31 or the heater 40 may also be controlled to rotate relatively in the inhalation stage.

[0169] In some embodiments, the method further comprises controlling the drive element 60 at the start of the pre-heating stage to drive either the holding element 31 or the heater 40 to rotate relative to the other.

[0170] By controlling and operating the driving element 60 at the start of the pre-heating stage, the holding element 31 and the heater 40 can be rotated relatively at the beginning when the heating of the heater 40 starts, and as the temperature of the heater 40 gradually increases, the holding element 31 and the heater 40 rotate relatively, so that the tobacco in the aerosol-generating product 1000 is less likely to adhere to the heater 40. In addition, by controlling the driving element 60 to start operating at the start of the pre-heating stage and to stop operating at the end of the pre-heating stage, the driving element 60 can be operated throughout the entire pre-heating stage, i.e., the holding element 31 and the heater 40 can be rotated relatively throughout the entire pre-heating stage, which is more advantageous in reducing the adhesion of the tobacco in the aerosol-generating product 1000 to the heater 40.

[0171] It should be noted that controlling the driving element 60 to start operating at the beginning of the pre-heating phase and stop operating at the end of the pre-heating phase can also provide feedback information to the user, i.e., the user can start inhaling when he observes that the aerosol-generating product 1000 has stopped rotating, i.e., when the aerosol-generating product 1000 stops rotating, it indicates that the pre-heating phase is over and the heater 40 has entered the inhalation phase and the user can start inhaling. In the case where rotation is stopped before the end of the pre-heating phase, additional feedback information is required to inform the user of the end of the pre-heating phase.

[0172] In some embodiments, the method further comprises controlling the drive element 60 to drive the holding element 31 to move and rotate the aerosol-generating product 1000 relative to the heater 40 .

[0173] Typically, the heater 40 has electrode leads electrically connected to the circuit board 22, so when the heater 40 rotates, the electrode leads also rotate synchronously, and the electrode leads become entangled; therefore, it is preferable to set the holding element 31 to rotate, thereby eliminating the need to improve the form of the electrical connection between the heater 40 and the main board 20.

[0174] In a further embodiment, during the rotation of the holding element 31, the rotation time is 15S or more, or the number of rotations is 3 or more, in order to better reduce the adhesion of tobacco in the aerosol-generating product 1000 to the heater 40. The longer the rotation time or the higher the number of rotations of the holding element 31, the more advantageous it is for reducing the adhesion of tobacco in the aerosol-generating product 1000 to the heater 40, but if the rotation time of the holding element 31 is too long or the number of rotations is too high, the power consumption increases accordingly. Alternatively, in a further embodiment, the rotation direction of the holding element 31 may include two directions, counterclockwise and clockwise. For example, when the rotation time of the holding element 31 is 15S, the holding element 31 may rotate counterclockwise within the first 7S and clockwise within the last 8S. Alternatively, the holding element 31 may change the rotation direction at predetermined time intervals. By changing the rotation direction, the adhesion of tobacco in the aerosol-generating product 1000 to the heater 40 can be further reduced.

[0175] In some embodiments, during the rotation of the holding element 31 or the heater 40, the aerosol generating device 100 provides a feedback information of the rotation to a user to improve the user's experience, the method further comprising: It may further comprise driving the lighting assembly in a process whereby either the holding element 31 or the heater 40 rotates relative to the other to produce a lighting effect different from that produced during the suction phase.

[0176] Specifically, the aerosol generating device 100 may be provided with a lighting assembly, which is electrically connected to the controller on the circuit board 22, and the controller may control the lighting assembly to generate a corresponding lighting effect. For example, in the inhalation stage, in this case, the holding element 31 or the heater 40 both stop rotating, and the controller may control the lighting assembly to generate a red light. When the holding element 31 or the heater 40 rotates in the pre-heating stage, the controller may control the lighting assembly to generate a different lighting effect from the inhalation stage, such as a blue light or a green light. In some embodiments, the lighting effect may be controlled to indicate the current rotation speed of the holding element 31 or the heater 40, for example, a blue light indicates a fast rotation speed, and a green light indicates a slow rotation speed. Alternatively, in some embodiments, the lighting effect may indicate whether the holding element 31 or the heater 40 is rotating, for example, a blue light indicates that the holding element 31 or the heater 40 is not rotating, and a green light indicates that the holding element 31 or the heater 40 is rotating.

[0177] Alternatively, in some embodiments, the feedback information further comprises vibration feedback, in which case the aerosol generating device 100 is provided with a vibration feedback element (not shown) electrically connected to a controller on the circuit board 22, the vibration feedback element being a motor, and the controller being capable of controlling the vibration feedback element to vibrate; The method further includes driving the vibration feedback element to generate vibration, wherein the sequence of driving the holding element 31 to move the aerosol generating product 1000 to stop rotation is synchronized or approximately synchronized with the sequence of driving the vibration feedback element to initiate vibration.

[0178] Specifically, the sequence in which the controller controls the rotation of the holding element 31 is substantially the same as the sequence in which the controller controls the vibration feedback element; that is, when the holding element 31 starts to rotate, the vibration feedback element also starts to vibrate, and when the holding element 31 stops to rotate, the vibration feedback element also stops vibrating, thereby enabling the user to determine whether the holding element 31 is rotating due to the vibration of the vibration feedback element.

[0179] An embodiment of the present application further provides a method for controlling an aerosol generating device 100, the method comprising: controlling a driving element 60 to drive and rotate a holding element 31 or a heater 40 within a predetermined time period, thereby relatively rotating an aerosol generating product 1000 in the holding element 31 and the heater 40; the method includes: This includes controlling the drive element 60 to drive either the holding element 31 or the heater 40 to rotate relative to the other within the first 25S of a heating period of the heater 40.

[0180] Specifically, the heating period of the heater 40 includes the above-mentioned preheating stage and suction stage, and the first 25 S may be in the preheating stage or the suction stage, and when the preheating stage time is short, the first 25 S is in the suction stage, and when the preheating stage time is long, the first 25 S is in the preheating stage. The holding element 31 or the heater 40 may always rotate within the first 25 S of the heating period, or may rotate within a specific time within the first 25 S, for example, preferably within the first 15 to 25 S of the heating period.

[0181] An embodiment of the present application further provides a method for controlling an aerosol generating system, the aerosol generating system including the aerosol generating device 100 and the aerosol generating product 1000 described in the above embodiments, the method comprising: The method includes controlling the driving element 60 to drive and rotate the holding element 31 during the pre-heating stage, thereby placing the aerosol generating product 1000 in a rotating state, and controlling the driving element 60 to stop operation during the suction stage, thereby placing the aerosol generating product 1000 in a stationary state.

[0182] Specifically, according to the description of the embodiment above, the holding element 31 can accommodate and hold the aerosol-generating product 1000 in its second cavity 51, so that when the driving element 60 drives and rotates the holding element 31, the holding element 31 can move and synchronously rotate the aerosol-generating product 1000, and can further rotate the aerosol-generating product 1000 relative to the heater 40. Thus, by controlling and rotating the holding element 31 in the pre-heating stage, the aerosol-generating product 1000 can be brought into a rotating state in the pre-heating stage, and by controlling the driving element 60 to stop operating in the inhalation stage, the aerosol-generating product 1000 can be brought into a stationary state in the inhalation stage, thereby reducing the adhesion of tobacco in the aerosol-generating product 1000 to the heater 40 due to high temperature in the pre-heating stage.

[0183] It should be noted that reducing the tendency of the aerosol-generating product 1000 to adhere to the heater 40 due to high temperatures during the heating process is not limited to the method of rotating the aerosol-generating product 1000 and the heater 40 relative to each other, and in some other embodiments, the holding element 31 and the heater 40 may be moved relative to each other, that is, the aerosol-generating product 1000 and the heater 40 may be moved relative to each other, for example, the aerosol-generating product 1000 and the heater 40 may be moved relatively up and down, left and right, or back and forth in space, as long as there is relative movement between the aerosol-generating product 1000 and the heater 40.

[0184] Example 3 An embodiment of the present application provides an aerosol generating device 100, which, as shown in Fig. 23-24 with reference to Fig. 18, includes a cavity 10A, a heater 40, a circuit board 22, a battery cell 21 and a holding element 31, the battery cell 21 and the heater 40 are both electrically connected to the circuit board 22, and the circuit board 22 includes a controller of the aerosol generating device 100, so that the controller of the aerosol generating device 100 can control the battery cell 21 to supply power to the heater 40. The holding element 31 is formed with a second cavity 51 defined therein, and at the same time, the holding element 31 is accommodated in the cavity 10A, and the second cavity 51 is used for receiving and holding an aerosol generating product 1000 to be used in combination with the aerosol generating device 100, i.e., the holding element 31 can receive the aerosol generating product 1000 and accommodate it in the cavity 10A. The heater 40 extends at least partially into the second cavity 51 and can be inserted into the aerosol generating product 1000 to heat and generate an aerosol. It is readily understood that the battery cell 21 can be a rechargeable or non-rechargeable battery cell.

[0185] The aerosol-generating product 1000 preferably employs a tobacco-containing material that releases volatile compounds from the substrate upon heating, or may be a non-tobacco material suitable for electrical heating to generate smoke after heating. The aerosol-generating product 1000 preferably employs a solid substrate, which may include one or more of the following powders, granules, elongated pieces, strips or sheets of vanilla leaf, tobacco leaf, homogenized tobacco, expanded tobacco, or the solid substrate may include additional tobacco or non-tobacco volatile flavor compounds to be released upon heating of the substrate. In this embodiment, the aerosol-generating product 1000 is described employing a cigarette filled with tobacco material therein.

[0186] The heater 40 is configured in the shape of a long, thin pin, needle, or sheet so that it can be smoothly inserted into and heated by the aerosol-generating product 1000. In some implementations, the heater 40 is a resistive heating element that generates Joule heat when supplied with a direct current. Alternatively, in some other implementations, the heater 40 is a sensitive heating element made of a sensitive material that can be penetrated by a changing magnetic field to generate heat. Alternatively, in some other implementations, the heater 40 is an infrared heating element that heats the aerosol-generating product 1000 by emitting infrared radiation.

[0187] In some embodiments, as shown in Figures 23 and 24, vertically extending ribs 52 are formed on the inner wall of the second cavity 51, and there are multiple ribs 52, which are evenly arranged around the inner wall of the second cavity 51, so that the holding space is surrounded by the multiple ribs 52, and thereby, when the aerosol-generating product 1000 is contained in the second cavity 51, it can be clamped by the multiple ribs 52 and held in the holding space.

[0188] 24 and 21, the retaining element 31 is formed with an open end 54 for receiving the aerosol-generating product 1000, and the aerosol-generating device 100 further includes a rotatable pulley 60A and a driving element 60, the driving element 60 includes a rotating shaft 61, which is connected to the rotatable pulley A and rotates the rotatable pulley 60A. At the same time, the retaining element 31 is provided with a driven pulley 31A which rotates to move the retaining element 31, and the aerosol-generating product 1000 is clamped by the ribs 52 and held in the first cavity 51, and there is sufficient friction between the aerosol-generating product 1000 and the ribs 52, so that when the retaining element 31 rotates, the aerosol-generating product 1000 can be moved and rotated synchronously. The driven pulley 31A is provided with a gear 531, and the rotatable pulley 60A and the driven pulley 31A are transmitted by gear meshing, so that when the driving element 70 drives and rotates the rotating shaft 61, the rotating shaft 61 moves and rotates the rotatable pulley 60A, which moves and rotates the driven pulley 31A, which further moves and rotates the aerosol-generating product 1000 relative to the heater 40, and under the action of this relative rotation, the adhesion of tobacco to the heater 40 in the aerosol-generating product 1000 can be effectively reduced.

[0189] In some embodiments, the driving element 60 is a cylinder or a hydraulic cylinder, etc. In addition, the transmission relationship between the rotatable pulley 60A and the holding element 31 is not limited to the gear meshing transmission, and in some embodiments, the transmission can be performed by a transmission mechanism such as a chain transmission, a worm gear, a swing link mechanism, a link mechanism, or a belt pulley. In a specific embodiment, for the belt transmission method shown in FIG. 22, the rotatable pulley 60A and the driven pulley 31A are both belt pulleys, and a transmission belt 61B, which can be a flexible belt, is provided between the rotatable pulley 60A and the driven pulley 31A, so that the rotation of the rotatable pulley 60A can move the transmission belt 61B, and the movement of the transmission belt 61B further moves and rotates the driven pulley 31A, thereby realizing the transmission between the rotatable pulley 60A and the holding element 31.

[0190] Continuing to refer to FIG. 24, the aerosol generating device 100 has a proximal end 110 and a distal end 120 arranged opposite each other in the longitudinal direction, and since the aerosol generating device 100 is usually designed to have a small volume so that it is easy for users to carry, both the driving element 60 and the circuit board 22 extend along the longitudinal direction of the aerosol generating device 100 so as to reduce the structural space occupied as much as possible, thereby avoiding a significant increase in the volume of the aerosol generating device 100 due to the addition of the driving element 60 to the aerosol generating device 100.

[0191] 25, in order to fully utilize the structural space, the circuit board 22 includes a first part 22A and a second part 22B, which are electrically connected to each other for communication and are arranged in different directions, that is, the first part 22A and the second part 22B are not present in the same complete circuit board 22. The first part 22A and the second part 22B are provided with corresponding electronic components, and dividing the circuit board 22 into the first part 22A and the second part 22B eliminates the need to integrate all the electronic components into one circuit board, which increases the volume of the circuit board 22 and is inconvenient for the structural design of other components.

[0192] 25, in a further embodiment, the connection part 33 of the first part 22A and the second part 22B is connected via an FPC (Flexible Printed Circuit, flexible circuit board 22). Since the FPC has the characteristics of being freely bendable and foldable, lightweight, thin, and easy to assemble, the FPC connection can improve the efficiency during production and assembly while maintaining the need for miniaturization of the aerosol generating device 100.

[0193] In a further embodiment, still referring to FIG. 25, the first portion 22A and the second portion 22B are perpendicular to each other to further facilitate production and assembly and to save construction space.

[0194] In a further embodiment, the first part 22A is arranged to pass small current signals, and the second part 22B is arranged to pass large current signals, for example, the first part 22A can be electrically connected to a low power device such as an LED light 311 or a switch button 312, and the second part 22B is electrically connected to a high power device such as a heater 40 or a battery cell 21, thereby separating the small current signals and the large current signals to reduce mutual interference.

[0195] In a further embodiment, as shown in FIG. 26, the first part 22A and the second part 22B define an accommodation space 34, and the driving element 60 extends into the accommodation space 34, thereby eliminating the need to provide the driving element 60 in another position, further saving structural space and advantageous in maintaining the small volume needs of the aerosol generating device 100.

[0196] 24, in some embodiments, in order to facilitate electrical connection between the circuit board 22 and the driving element 60, the circuit board 22 and the driving element 60 are provided on the same side of the holding element 31, i.e., on the same side of the cavity 10A, so that the circuit board 22 is close to the driving element 60 and the electrical connection between the driving element 60 and the circuit board 22 is facilitated. In further embodiments, in order to prevent the high temperature of the heater 40 from being transferred to the electronic components on the circuit board 22 and affecting the reliability of the electronic components on the circuit board 22, the driving element 60 extends between the cavity 10A and the circuit board 22, and keeps the circuit board 22 as far away from the cavity 10A as possible, preventing the high temperature of the heater 40 in the cavity 10A from being transferred to the electronic components on the circuit board 22.

[0197] In some embodiments, the rotatable pulley 60A is provided at the proximal end of the aerosol generation device 100, such that the rotation shaft 61 of the drive element 60 extends therethrough to drive the rotation thereof. However, providing the rotatable pulley 60A at the proximal end of the aerosol generation device 100 is advantageous in terms of saving space structure.

[0198] In a further embodiment, at least a portion of the housing at the proximal end of the aerosol generating device 100 is transparent, thereby allowing a user to directly observe the rotation of the rotatable pulley 60A and / or the rotation of the driven pulley 31A on the retaining element 31 through the transparent portion, thereby enhancing the high-tech and cool feel of the aerosol generating device 100.

[0199] It should be noted that the specification and drawings of the present application show preferred embodiments of the present application, but are not limited to the embodiments described herein; further, those skilled in the art may make improvements and modifications based on the above description, and all such improvements and modifications shall fall within the scope of protection of the appended claims of the present application.
