Description

TECHNICAL FIELD

[0001] The utility model relates to electronic smoking set field, especially a kind of aerosol generating device. BACKGROUND

[0002] There are mainly three types of cigarette lifting structures used in aerosol generating devices on the market: user rotating cigarette (i.e., aerosol generating article) lifting, motor-assisted lifting and IQOS type mechanical lifting. Among them, IQOS is a heat-not-burn (Heat Not Burn) tobacco product launched by Philip Morris International. The name is an abbreviation of "INTELLIGENT QUITTING SMOKING SYSTEM", which translates to "Intelligent Smoking Cessation System", but in fact it is not a smoking cessation tool, but a new type of aerosol generating device.

[0003] For aerosol generating devices provided with a circumferentially symmetrical heating body, the user can extract the aerosol generating article by rotating the aerosol generating article. User rotating cigarette lifting refers to the user holding the mouthpiece and repeatedly rotating the cigarette clockwise and counterclockwise, which drives the smoking material to separate from the heating body through the resistance between the smoking materials. However, this lifting method requires users to deliberately learn. In addition, users are prone to forget to rotate the cigarette when using the aerosol generating device and directly pull the cigarette out of the aerosol generating device, which causes the smoking material to fall into the heating cavity, making it inconvenient for the user to use the aerosol generating device subsequently.

[0004] In the IQOS product, the shell and the internal lifting structure are connected through a transmission component. The user performs an upward pushing action on the shell, i.e., the user applies an upward pushing force on the shell, which drives the internal lifting structure to move upward through the transmission component, causing the aerosol generating article in the lifting structure to move upward, thereby achieving the separation of the aerosol generating article from the heating body and preventing the smoking segment in the aerosol generating article from adhering to the heating body, which causes the smoking material to fall inside the aerosol generating device. Many cigarette companies currently use similar lifting structures in their products. Although this lifting structure is simple. However, this lifting structure needs to connect the lifting structure and the shell through a transmission component, and the mass of the transmission component increases the thermal load of the aerosol generating device. At the same time, due to the large connection area and contact area of the lifting structure, the transmission component and the shell, it increases the heat conduction of the aerosol generating device. When too much heat is conducted to the surface of the aerosol generating device, if the surface temperature is too high, it will cause the user's experience to decrease.

[0005] The principle of the motor-assisted cigarette lifting structure is similar to that of the IQOS, except that the motor-assisted cigarette lifting structure provides power for the cigarette lifting structure by a motor. The motor-assisted cigarette lifting structure converts the rotational work of the motor into the axial linear motion of the cigarette lifting structure. The motor-assisted cigarette lifting structure needs to provide a motor and install it in the aerosol generating device, which not only increases the components and space occupation of the device, but also increases the difficulty of circuit design in the aerosol generating device. Furthermore, the motor and the cigarette lifting structure are connected by a transmission structure such as a lead screw structure, which is complex in structure design, high in production cost, and increases heat conduction of the aerosol generating device.

[0006] With the development of technology, aerosol generating devices with a cigarette lifting structure using magnetic attraction principle have appeared. That is, the cigarette lifting structure and the body of the aerosol generating device are respectively provided with magnets that attract each other. When the aerosol generating device is used, the cigarette lifting structure can be attracted and fixed to the body. When the cigarette is lifted, a force greater than the attractive force is used to release the attraction between the cigarette lifting structure and the body. However, the aerosol generating device has many problems. If the magnetic attraction between the cigarette lifting structure and the body of the aerosol generating device is too large, it is very laborious to lift the cigarette lifting structure, which will cause a series of problems, such as the cigarette being suddenly lifted with great force, which is easy to cause the aerosol generating substrate in the smoking segment of the cigarette to fall into the aerosol generating device, which is not easy to clean and brings bad user experience. If the magnetic attraction between the cigarette lifting structure and the body of the aerosol generating device is too small, it is not convenient for users to use. Utility model content

[0039] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail in combination with the drawings.

[0040] Figure 1 and Figure 2 An aerosol generating system is shown, which includes an aerosol generating device 0 and an aerosol generating article 3 provided by the utility model.

[0041] In some possible embodiments provided by the utility model, reference is made to Figure 3 , Figure 4 and in combination withFigure 1 and Figure 2 An aerosol-generating device 0 comprises a smoking extractor 1 and a body 2.

[0042] The smoking extractor 1 is configured to accommodate an aerosol-generating article 3. The smoking extractor 1 is provided with a first magnet unit 11. Figure 3 to Figure 4 The smoking extractor 1 is exemplarily a smoking tube as shown.

[0043] The body 2 is provided with a driving assembly 5, and the driving assembly 5 is provided with a second magnet unit 21. Figure 3 、 Figure 4 and in combination with Figure 5 The movement of the driving assembly 5 can move the second magnet unit 21 relative to the first magnet unit 11 between a first position D and a second position E. When the second magnet unit 21 is located at the first position D, the second magnet unit 21 and the first magnet unit 11 are mutually adsorbed, so that the smoking extractor 1 and the body 2 are adsorbed and fixed. When the second magnet unit 21 is located at the second position E, the second magnet unit 21 and the first magnet unit 11 are unadsorbed, so that the smoking extractor 1 and the body 2 are unadsorbed and fixed.

[0044] In this embodiment, referring to Figure 3 and Figure 1 When the second magnet unit 21 is located at the first position D, the second magnet unit 21 and the first magnet unit 11 are mutually adsorbed, and the smoking extractor 1 and the body 2 have a large adsorption force, so that the smoking extractor 1 is stably adsorbed and fixed to the body 2, and it is difficult to extract the smoking extractor 1 and the aerosol-generating article 3 located therein. If the smoking extractor 1 is forcibly extracted, the aerosol-generating substrate in the smoking segment of the aerosol-generating article 3 will fall into the heating cavity, which is not easy to clean and is not convenient for the user to use the aerosol-generating device 0 subsequently, and the user will have a bad experience.

[0045] Referring to Figure 2 and Figure 5 When the second magnet unit 21 is located at the second position E, the second magnet unit 21 and the first magnet unit 11 are unadsorbed, the adsorption force between the smoking extractor 1 and the body 2 is weakened, and the body 2 unadsorbs and fixes the smoking extractor 1, so that the smoking extractor 1 and the aerosol-generating article 3 located therein are easily extracted.

[0046] In the utility model, the driving assembly can move along the radial direction of the aerosol-generating device, can rotate along the circumferential direction of the aerosol-generating device, and can also move along the axial direction of the aerosol-generating device, and the utility model does not limit this, as long as the movement of the driving assembly can move the second magnet unit relative to the first magnet unit between the first position and the second position, so that the smoking extractor and the body are adsorbed and fixed or unadsorbed and fixed.

[0047] In the present embodiment, the driving assembly rotates along the circumference of the aerosol-generating device to move the second magnet unit relative to the first magnet unit between the first position and the second position, so that the cigarette lifter is adsorbed and fixed to the body or released from the adsorption and fixation. Figure 5 、 Figure 1 and Figure 2 The state conversion of the mutual adsorption and release of the second magnet unit 21 and the first magnet unit 11 is realized by moving the second magnet unit 21 between the first position D and the second position E, and further, the state switching of the aerosol-generating article 3 being more firmly fixed in the cigarette lifter 1 and being easily extracted from the cigarette lifter 1 is realized, which makes the cigarette lifting operation of the aerosol-generating device 0 simple, convenient and fast, and makes the user have a good experience.

[0048] In other possible embodiments, the driving assembly moves along the axis of the aerosol-generating device to move the second magnet unit relative to the first magnet unit between the first position and the second position, so that the cigarette lifter is adsorbed and fixed to the body or released from the adsorption and fixation. For example, the driving assembly is a toggle, and the second magnet unit is arranged on the toggle. The toggle can move along the axis. When the toggle is pulled up, the second magnet unit is located at the first position, and the second magnet unit and the first magnet unit are mutually adsorbed, so that the cigarette lifter is adsorbed and fixed to the body. When the toggle is pressed down, the second magnet unit is located at the second position, and the second magnet unit and the first magnet unit are released from the adsorption, so that the cigarette lifter is released from the adsorption and fixation to the body.

[0049] With the above technical solution, the first magnet unit 11 is arranged on the cigarette lifter 1, and the second magnet unit 21 is arranged on the body 2. The characteristics of the opposite poles of the first magnet unit 11 and the second magnet unit 21 are used to move the cigarette lifter 1 relative to the body 2 to extract the aerosol-generating article 3. The aerosol-generating device 0 omits the conveying structure, so that the connecting structure is simple, and the number of components is also reduced.

[0050] In the first embodiment of the present utility model, the first magnet unit includes a sub-magnet one and a sub-magnet two, and the sub-magnet one and the sub-magnet two are arranged opposite along the radial direction of the aerosol-generating device 0. The second magnet unit includes a sub-magnet three and a sub-magnet four, and the sub-magnet three and the sub-magnet four are arranged opposite along the radial direction of the aerosol-generating device 0.

[0051] When the second magnet unit is in the first position, the sub-magnet one and the sub-magnet three are arranged opposite to each other and are mutually attracted, and the sub-magnet two and the sub-magnet four are arranged opposite to each other and are mutually attracted, so that the cigarette lifter 1 is attracted and fixed on the body. When the second magnet unit is in the second position, the sub-magnet one and the sub-magnet four are arranged opposite to each other and are mutually repelled, and the sub-magnet two and the sub-magnet two are arranged opposite to each other and are mutually repelled, so that the cigarette lifter is repelled in the body. Rotating the second magnet unit in the first position by 180° along the circumference can reach the second position.

[0052] By changing the relative positions of the sub-magnet one, the sub-magnet two, the sub-magnet three and the sub-magnet four, the attraction and repulsion states of the first magnet unit and the second magnet unit are changed, and the attraction and repulsion of the cigarette lifter and the body are realized. When the cigarette lifter and the body are attracted, the cigarette lifter is stably fixed and attracted in the body, facilitating the insertion of the aerosol generating article in place. When the cigarette lifter and the body are repelled, the cigarette lifter is easily extracted from the body. Further, when the cigarette lifter and the body are repelled, the cigarette lifter is subjected to a larger repelling force, so that the cigarette lifter and the aerosol generating article located therein move upward along the axial direction of the aerosol generating device, realizing the extraction of the aerosol generating article.

[0053] In the second embodiment of the present application, with reference to Figure 5 and in combination with Figure 1 to Figure 3 , the driving assembly 5 is provided with a third magnet unit 22.

[0054] In some possible embodiments, the synchronous movement of the second magnet unit and the third magnet unit can be realized by the movement of one component in the driving assembly 5. Exemplarily, with reference to Figure 5 , the driving assembly 5 includes a rotating member, and the second magnet unit 21 and the third magnet unit 22 are arranged on the rotating member. The second magnet unit 21 includes two second magnets, which are arranged opposite to each other along the radial direction R of the aerosol generating device 0. The third magnet unit 22 includes two third magnets, which are arranged opposite to each other along the radial direction R. Each second magnet and each third magnet are arranged apart along the circumferential direction Q of the aerosol generating device 0. Since the second magnet unit 21 and the third magnet unit 22 are both arranged on the rotating member, rotating the rotating member can realize the synchronous movement of the second magnet unit 21 and the third magnet unit 22.

[0055] In other possible embodiments, the movement of the second magnet unit and the third magnet unit is realized by the movement of different components in the driving assembly 5, respectively.

[0056] Whether the same component in the driving assembly 5 drives the second magnet unit and the third magnet unit to realize synchronous movement or different components in the driving assembly 5 respectively drive the second magnet unit and the third magnet unit to move. In any case, the movement of the driving assembly 5 can enable the third magnet unit 22 to move relative to the first magnet unit 11 between the first position D and a third position (not shown in the figure). When the third magnet unit 22 is located at the first position D, the third magnet unit 22 and the first magnet unit 11 repel each other, so that the cigarette lifter 1 is repelled in the body 2. When the third magnet unit 22 is located at the third position, the third magnet unit 22 and the first magnet unit 11 are no longer repelled, so that the cigarette lifter 1 is no longer repelled in the body 2.

[0057] In some possible embodiments, when the third magnet unit 22 is located at the first position D, the third magnet unit 22 and the first magnet unit 11 repel each other, so that the cigarette lifter 1 is easily extracted from the body 2.

[0058] In the present embodiment, when the third magnet unit 22 is located at the first position D, the third magnet unit 22 and the first magnet unit 11 repel each other, and the cigarette lifter 1 and the aerosol generating article 3 located therein move upward along the axial direction Z of the aerosol generating device 0 under the action of the repulsive force (as shown in Figure 2 ), that is, move towards the direction away from the aerosol generating device 0, so that the aerosol generating article 3 is separated from the position that can be normally heated for smoking, and the extraction of the aerosol generating article 3 is realized.

[0059] The state conversion of the third magnet unit 22 and the first magnet unit 11 repelling each other and no longer repelling each other is realized by the movement of the third magnet unit 22 between the first position D and the third position. By the principle of repulsion between the same poles, the extraction of the aerosol generating article 3 can be realized by using the third magnet unit 22 and the first magnet unit 11, without the need for the user to manually extract the aerosol generating article 3, which makes the cigarette lifting operation of the aerosol generating device 0 more simple, convenient and fast, and the user has a better experience.

[0060] In some possible embodiments of the present utility model, referring to Figure 3 and Figure 5 , the first position D is opposite to the first magnet unit 11 along the axial direction Z of the aerosol generating device 0. The second position E is staggered with the first magnet unit 11 along the axial direction Z.

[0061] Referring to Figure 3 , when the second magnet unit 21 is located at the first position D, the second magnet unit 21 and the first magnet unit 11 are opposite to each other along the axial direction Z of the aerosol generating device 0, and the adsorption force between the second magnet unit 21 and the first magnet unit 11 is the largest, so that the cigarette lifter 1 is stably adsorbed and fixed in the body 2.

[0062] When the second magnet unit 21 is located at the second position E, the second magnet unit 21 is staggered with the first magnet unit 11 along the axial direction Z of the aerosol-generating device 0, the attractive force between the second magnet unit 21 and the first magnet unit 11 is weakened, and the attractive force between the cigarette lifter 1 and the body 2 is weakened, facilitating the extraction of the cigarette lifter 1 and the aerosol-generating article 3 located therein.

[0063] In some possible embodiments of the present application, the first position D is opposite to the first magnet unit 11 along the axial direction Z of the aerosol-generating device 0. The third position is staggered with the first magnet unit 11 along the axial direction Z.

[0064] When the third magnet unit 22 is located at the first position D, the third magnet unit 22 is opposite to the first magnet unit 11 along the axial direction Z of the aerosol-generating device 0, and the repulsive force between the third magnet unit 22 and the first magnet unit 11 is the largest, so that the cigarette lifter 1 is repelled in the body 2 and is easy to be extracted. Further, when the repulsive force between the third magnet unit 22 and the first magnet unit 11 is the largest and is equal to or greater than the gravity of the cigarette lifter 1 and the aerosol-generating article 3 located therein, the cigarette lifter 1 can move upward along the axial direction Z of the aerosol-generating device 0, i.e., in the Z1 direction, under the action of the repulsive force, thereby achieving the extraction of the aerosol-generating article 3.

[0065] When the third magnet unit 22 is located at the third position, the third magnet unit 22 is staggered with the first magnet unit 11 along the axial direction Z of the aerosol-generating device 0, the repulsive force between the third magnet unit 22 and the first magnet unit 11 is weakened, and the repulsive force between the cigarette lifter 1 and the body 2 is weakened, so that the cigarette lifter 1 can move upward along the axial direction Z of the aerosol-generating device 0 for a limited distance. Even when there is no repulsive force between the third magnet unit 22 and the first magnet unit 11, there is no repulsive force between the cigarette lifter 1 and the body 2, and the cigarette lifter 1 will not displace along the axial direction Z of the aerosol-generating device 0.

[0066] As mentioned above, Figure 5 It is shown that the second magnet unit 21 and the third magnet unit 22 are both arranged on the rotating member, and the synchronous movement of the second magnet unit 21 and the third magnet unit 22 can be achieved by rotating the rotating member. In this embodiment, reference is made to Figure 3 、 Figure 4 and Figure 5, the second magnet unit 21 is located at the first position D, the second magnet unit 21 is arranged opposite to the first magnet unit 11 along the axial direction Z of the aerosol generating device 0, and the third magnet unit 22 is staggered along the axial direction Z of the first magnet unit 11. When the third magnet unit 22 is located at the first position D, the third magnet unit 22 is arranged opposite to the first magnet unit 11 along the axial direction Z of the aerosol generating device 0, and the second magnet unit 21 is staggered along the axial direction Z of the first magnet unit 11. That is, in fact, the first magnet unit 11 and the second magnet unit 21 are arranged apart along the axial direction Z; the first magnet unit 11 and the third magnet unit 22 are arranged apart along the axial direction Z.

[0067] In some possible embodiments of the present application, with reference to Figure 5 and in combination with Figure 3 , the aerosol generating device 0 comprises a driving assembly 5 for driving the second magnet unit 21 to move between the first position D and the second position E and / or the third magnet unit 22 to move between the first position D and the third position.

[0068] The driving assembly 5 can be electrically driven, for example, by a motor, or manually driven, for example, by a knob or a rotating member.

[0069] The driving assembly 5 comprises a rotating member 51, which is capable of rotating along the circumferential direction Q of the aerosol generating device 0. Preferably, the second magnet unit 21 and the third magnet unit 22 are arranged apart along the circumferential direction Q on the rotating member 51 and are capable of rotating with the rotating member 51.

[0070] For example, the rotating member is in the shape of "X", and for another example, the rotating member is in the shape of "+". Preferably, the rotating member 51 is a rotating disc.

[0071] Further, in some possible embodiments, the second position and the third position are the same position. When the second magnet unit 21 is located at the first position D, the third magnet unit 22 is located at the second position E, and when the second magnet unit 21 is located at the second position E, the third magnet unit 22 is located at the first position D.

[0072] With reference to Figure 3 to Figure 5 , the second magnet unit 21 and the third magnet unit 22 are arranged on the rotating member 51 and are capable of moving between the first position D and the second position E with the rotation of the rotating member 51, which ingeniously realizes the switching between the mutual attraction and mutual repulsion of the cigarette lifter 1 and the body 2, so that the cigarette lifter 1 moves along the axial direction Z, especially moves upward along the axial direction Z, and the aerosol generating article 3 is quickly and conveniently extracted. At the same time, the aerosol generating device 0 has a simple structure design, which reduces the production cost.

[0073] In some possible embodiments of the present application, with reference to Figure 3and Figure 4 The aerosol-generating device 0 comprises a heating body 4 extending along the axial direction Z. A hole 14 is provided at the geometric center of the bottom of the cigarette holder 1 for the heating body 4 to pass through.

[0074] The shape of the hole 14 is adapted to the shape of the heating body 4 so that the heating body 4 can pass through the hole 14. For example, the heating body 4 is a heating needle, and the hole 14 is circular; or the heating body 4 is a sheet, and the hole 14 is rectangular. The shape of the heating body 4 and the hole 14 is not limited in the present application, as long as the shape of the hole 14 is adapted to the shape of the heating body 4, and the heating body 4 can pass through the hole 14.

[0075] Compared with the method of rotating the cigarette (i.e. the aerosol-generating article 3) by the user, the aerosol-generating device 0 provided by the present application does not need to rotate the aerosol-generating article 3 along the circumferential direction Q, but only relies on the cooperation of different magnet units to realize the movement of the cigarette holder 1 and the aerosol-generating article 3 located therein along the axial direction Z, thereby realizing the extraction of the aerosol-generating article 3. Therefore, the aerosol-generating device 0 provided by the present application is not limited to use in the aerosol-generating device 0 provided with the heating body 4 symmetrical along the circumferential direction Q, but can also be used in the aerosol-generating device 0 provided with the heating body 4 asymmetrical.

[0076] In some possible embodiments of the present application, with reference to Figure 1 to Figure 4 The cigarette holder 1 has an adsorption position F and an extraction position T relative to the body 2. The cigarette holder 1 can move between the adsorption position F and the extraction position T. With reference to Figure 1 At the adsorption position F, the aerosol-generating article 3 located in the cigarette holder 1 is embedded in the body 2. With reference to Figure 2 At the extraction position T, the aerosol-generating article 3 located in the cigarette holder 1 is exposed more from the body 2 than at the adsorption position F. With reference to Figure 3 and Figure 5 When the second magnet unit 21 is located at the first position D, the cigarette holder 1 is adsorbed by the body and moves to the adsorption position F. When the third magnet unit 22 is located at the first position D, the cigarette holder 1 is repelled by the body and moves to the extraction position T.

[0077] In the present embodiment, the adsorption position F of the cigarette holder 1 is located below the extraction position T thereof along the axial direction Z, and the cigarette holder 1 located at the adsorption position F can move upward along the axial direction Z to reach the extraction position T. With reference to Figure 1 to Figure 5 When the second magnet unit 21 is located at the first position D, the cigarette holder 1 is adsorbed and moves to the adsorption position F. At the adsorption position F, the aerosol-generating article 3 can be inserted in place and heated. When the third magnet unit 22 is located at the first position D, the cigarette holder 1 is repelled and moves to the extraction position T, thereby realizing the extraction of the aerosol-generating article 3.

[0078] In the present embodiment, reference is made to Figure 3 , the adsorption position F is a position in which the aerosol generating article 3 can be normally heated for smoking in the holder 1. It is also a position in which the aerosol generating article 3 can be inserted into the holder 1.

[0079] Specifically, the insertion of the aerosol generating article 3 into the holder 1 means that the aerosol generating article 3 is inserted into the holder 1, and the aerosol generating article 3 moves downward along the axial direction Z of the aerosol generating device 0, i.e., moves along the Z2 direction or moves toward the inside of the aerosol generating device 0, until the bottom end of the aerosol generating article 3, i.e., the end away from the filter, contacts the stop portion of the holder 1 to prevent further insertion of the aerosol generating article 3. At this time, the aerosol generating article 3 is installed in place. After the aerosol generating article 3 is installed in place, the aerosol generating article 3 can be normally heated.

[0080] The extraction position T is a position in which the holder 1 is detached from the aerosol generating article 3 and the aerosol generating article 3 can be normally heated for smoking. Exemplarily, the extraction position T is shown in Figure 4 . It is also a position in which the aerosol generating article 3 is extracted from the holder 1.

[0081] Specifically, the extraction of the aerosol generating article 3 from the holder 1 means that the aerosol generating article 3 moves upward along the axial direction Z of the aerosol generating device 0, i.e., moves toward the outside of the aerosol generating device 0, and the heating body 4 is separated from the aerosol generating article 3.

[0082] Continuing to refer to Figure 3 and Figure 4 , in some possible embodiments provided by the present utility model, the aerosol generating device 0 further comprises a guide 6 and a sliding member 7. One of the guide 6 and the sliding member 7 is arranged on the body 2, and the other is arranged on the holder 1. Through cooperation of the guide 6 and the sliding member 7, the holder 1 moves between the adsorption position F and the extraction position T.

[0083] Exemplarily, the sliding member 7 can be a roller, a ball, or a bearing. The guide 6 can be a guide rail.

[0084] Referring to Figure 3 and Figure 4 , in the present embodiment, the guide 6 extends along the axial direction Z of the aerosol generating device 0. The sliding member 7 is connected to the holder 1 and located on the guide 6. The holder 1 moves between the adsorption position F and the extraction position T along the guide 6 through the sliding member 7.

[0085] In the present embodiment, the holder 1 moves between the adsorption position F and the extraction position T through rolling friction of the guide 6 and the sliding member 7. The rolling friction effectively reduces the movement resistance of the holder 1.

[0086] In some possible embodiments of the utility model, the sliding member 7 is spherical. That is, the sliding member 7 is a ball. The sliding member 7 is preferably made of a non-polar material, such as PA (polyamide), PC (polycarbonate), PEEK (polyether ether ketone), etc. In some possible embodiments, the guide member 6 is preferably made of a non-polar material of rigid material, avoiding using a material with good thermal conductivity as the material of the guide member 6, and reducing the heat conduction of the aerosol generating device 0.

[0088] Exemplarily, the limiting structure can include a slot 02 arranged on the shell 01 and a stopper (for example, a dial stopper) arranged on the rotating member 51, and the stroke of the stopper can be limited by the width of the slot 02 (that is, the size of the slot 02 in the circumferential direction), thereby limiting the circumferential movement of the rotating member 51.

[0089] Alternatively, referring to Figure 5 , the driving assembly 5 includes a fixed shaft 52, and the limiting structure includes a limiting portion 521 arranged on the fixed shaft 52 and a stop block 511 arranged on the rotating member 51.

[0090] The limiting portion 521 is arranged on the fixed shaft 52 and protrudes in the radial direction R of the aerosol generating device 0. The rotating member 51 is sleeved on the fixed shaft 52, and the rotating member 51 rotates around the fixed shaft 52, that is, the rotating member 51 moves in the circumferential direction Q around the fixed shaft 52.

[0091] The stop block 511 is arranged on the rotating member 51 and protrudes in the radial direction R. The limiting portion 521 cooperates with the stop block 511 to block the movement of the stop block 511, thereby limiting the rotation of the rotating member 51 by a predetermined angle.

[0092] As shown in Figure 5 , the rotating member 51 is annular. The rotating member 51 includes a sleeving member 53 for sleeving the rotating member 51 on the fixed shaft 52, so that the rotating member 51 can move in the circumferential direction Q around the fixed shaft 52. The rotating member 51 is provided with the stop block 511, which protrudes in the radial direction R and is arranged on the rotating member 51. One end of the stop block 511 is connected to the sleeving member 53, and the other end is connected to the rotating member 51.

[0093] Exemplarily, as shown in Figure 5As shown, the rotating member 51 is provided with two blocks, which are a first block 511A and a second block 511B. The first block 511A and the second block 511B are oppositely arranged along the radial direction R. The fixed shaft 52 is provided with a limiting portion 521 protruding along the radial direction R. The initial position is that the first block 511A is in contact with the limiting portion 521. When the rotating member 51 is rotated by 180° clockwise, the limiting portion 521 blocks the second block 511B from continuing to move clockwise. In the embodiment, the limiting portion 521 cooperates with the block to limit the predetermined angle of rotation of the rotating member 51 to 180°.

[0094] In some possible embodiments of the utility model, as shown in Figure 5 As shown, the second magnet unit 21 and the third magnet unit 22 are arranged at intervals along the circumferential direction Q on the rotating member 51. The second magnet unit 21 includes two second magnets. The third magnet unit 22 includes two third magnets. Each second magnet and each third magnet are arranged at intervals on the rotating member 51 along the circumferential direction Q.

[0095] Referring to Figure 3 to Figure 5 , the third magnet unit 22 is located at the second position E, the second magnet unit 21 is located at the first position D, the second magnet unit 21 is attracted to the first magnet unit 11, the cigarette lifter 1 is located at the adsorption position F, and the aerosol generating article 3 can be inserted into position. The rotating member 51 is rotated by 90° clockwise, the second magnet unit 21 is switched to the second position E, the third magnet unit 22 is switched to the first position D, the third magnet unit 22 is repelled from the first magnet unit 11, so that the cigarette lifter 1 moves upward along the axial direction Z until the cigarette lifter 1 is located at the lifting position, facilitating the lifting of the aerosol generating article 3.

[0096] In other possible embodiments, the rotating member 51 is provided with two blocks, which are a third block and a fourth block (not shown in the figure). The third block and the fourth block are arranged on the rotating member 51 and protrude along the radial direction R. The third block and the fourth block are 90°. The initial position is that the third block is in contact with the limiting portion 521. When the rotating member 51 is rotated by 90° clockwise, the limiting portion 521 blocks the third block from continuing to move clockwise. The limiting portion 521 cooperates with the block to limit the predetermined angle of rotation of the rotating member 51 to 90°.

[0097] In some other possible embodiments, in the aerosol generating device 0 provided by the utility model, the predetermined angle of rotation of the rotating piece 51 can be limited by setting the positions of the limiting part 521 and the stopper 511 according to actual needs and specific circumstances, and the utility model does not make any limitation on this. In some other possible embodiments, in the aerosol generating device 0 provided by the utility model, the limiting structure of the predetermined angle of rotation of the rotating piece 51 is not limited to the form of the limiting part 521 and the stopper 511 provided in the embodiment, and the utility model does not make any limitation on this, as long as it can realize the rotation of the rotating piece 51 by a predetermined angle.

[0098] Exemplarily, the limiting structure of the predetermined angle of rotation of the rotating piece 51 can be in the form of concave-convex cooperation, for example, a convex part is arranged on the outer surface of the fixed shaft 52, and a concave part is arranged on the inner surface of the sleeving piece 53, and the predetermined angle of rotation of the rotating piece 51 is limited by the concave-convex cooperation. Or, a concave part is arranged on the outer surface of the fixed shaft 52, and a convex part is arranged on the inner surface of the sleeving piece 53, and the predetermined angle of rotation of the rotating piece 51 is limited by the concave-convex cooperation. The limiting structure of the predetermined angle of rotation of the rotating piece 51 can also be in the form of clamping, for example, a clamping piece is arranged on the outer surface of the fixed shaft 52, and an engaging piece is arranged on the inner surface of the sleeving piece 53, and the predetermined angle of rotation of the rotating piece 51 is limited by the clamping form. Or, an engaging piece is arranged on the outer surface of the fixed shaft 52, and a clamping piece is arranged on the inner surface of the sleeving piece 53, and the predetermined angle of rotation of the rotating piece 51 is limited by the clamping form.

[0099] In some other possible embodiments, the fixed shaft is provided with a limiting part. The limiting part is arranged on the fixed shaft and protrudes along the radial direction of the aerosol generating device, and the limiting part extends along the axial direction. As shown in the figure, Figure 5 The driving assembly shown in the figure is hollow except for the sleeving piece, the stopper, the rotating piece 51, and the second magnet unit 21 and the third magnet unit 22 arranged on the rotating piece 51. That is to say, the space formed by the inner side of the sleeving piece 53, the stopper, and the rotating piece is a hollow part. The limiting part is arranged to protrude along the radial direction R and extend along the axial direction Z, and the part extending along the axial direction of the limiting part extends into the aforementioned hollow part. In this way, the part extending along the axial direction of the limiting part can be in contact with the stopper, and the limiting part is blocked by the stopper and can no longer move along the circumferential direction. In this way, the limiting part and the stopper can cooperate to limit the rotation of the rotating piece by a predetermined angle.

[0100] In some other possible embodiments, the driving assembly 5 comprises a rotating shaft. The rotating member 51 rotates with the rotation of the rotating shaft. The fixed structure of the rotating shaft is provided with a limiting portion. The limiting portion is provided on the fixed structure of the rotating shaft and protrudes along the radial direction of the aerosol generating device 0. The rotating member 51 is sleeved on the rotating shaft. The rotating member 51 is provided with a stopper, and the stopper is provided on the rotating member 51 and protrudes along the radial direction. The limiting portion cooperates with the stopper to block the movement of the stopper and limit the rotation of the rotating member 51 by a predetermined angle.

[0101] Reference Figure 5 In the present embodiment, the rotating member 5 is annularly symmetrical, with a hollow center, which reduces the mass of the rotating member 5 and the mass of the aerosol generating device 0.

[0102] In some possible embodiments of the present application, the aerosol generating device 0 comprises an elastic member (not shown in the figure). The elastic member is used to assist the lifting device 1 to recover from the lifting position T to the adsorbing position F.

[0103] One end of the elastic member is connected to the rotating member 51, and the other end is connected to the non-moving part. Preferably, one end of the elastic member is connected to the rotating member 51, and the other end is connected to the fixed shaft 52.

[0104] Exemplarily, the elastic member can be a spring or a torsion spring or an elastic sheet.

[0105] In the present embodiment, after the user releases his hand, the rotating member 51 can automatically reset to the second magnet unit 21 located at the first position D, so that the lifting device 1 is adsorbed by the body 2, and the lifting device 1 will reset to the adsorbing position F. Therefore, the setting of the elastic member realizes the automatic recovery of the lifting device 1 from the lifting position T to the adsorbing position F, realizes the automation of the aerosol generating device 0, and is convenient for the user to use.

[0106] Reference Figure 1 and Figure 2 and in combination Figure 3 and Figure 5 In some possible embodiments of the present application, the aerosol generating device 0 comprises a housing 01. The housing 01 is provided with a groove 02. The outer peripheral side surface of the rotating member 51 is exposed from the groove 02, so that the outer peripheral side surface of the rotating member 51 can be driven to rotate the rotating member 51, and further enable the second magnet unit 21 and / or the third magnet unit 22 to be placed at the first position D respectively with the rotation of the rotating member 51.

[0107] Exemplarily, the extension on the rotating member 51 is exposed from the groove 02 (not shown in the figure).

[0108] Preferably, as shown in Figure 1 and Figure 2 , the outer peripheral side surface of the rotating member 51 is exposed from the groove 02, and the user can directly contact the rotating member 51 and push the rotating member 51 to rotate.

[0109] In some possible embodiments, the rotating member is provided with a second magnet unit. The outer circumferential side of the rotating member is exposed from the groove, and a user can directly contact the rotating member and push the rotating member to rotate, so that the second magnet unit provided on the rotating member is switched between the first position and the second position. When the second magnet unit is located at the first position, the second magnet unit and the first magnet unit are attracted to each other, so that the cigarette lifter and the body are fixed by attraction; when the second magnet unit is located at the second position, the second magnet unit and the first magnet unit are separated from each other, so that the cigarette lifter and the body are separated from each other.

[0110] In other possible embodiments, referring to Figure 5 , the rotating member 51 is provided with a second magnet unit 21 and a third magnet unit 22, and the second magnet unit 21 and the third magnet unit 22 are uniformly spaced along the circumferential direction Q of the rotating member 51. The outer circumferential side of the rotating member 51 is exposed from the groove 02, and a user can directly contact the rotating member 51 and push the rotating member 51 to rotate, so that the second magnet unit 21 and the third magnet unit 22 can be respectively located at the first position D with the rotation of the rotating member 51. When the second magnet unit 21 is located at the first position D, the third magnet unit 22 is located at the second position E, the second magnet unit 21 and the first magnet unit 11 are attracted to each other, so that the cigarette lifter 1 and the body 2 are fixed by attraction, and the cigarette lifter 1 is located at the attraction position F; when the third magnet unit 22 is located at the first position D, the second magnet unit 21 is located at the second position E, and the third magnet unit 22 and the first magnet unit 11 are repelled from each other, so that the cigarette lifter 1 and the body 2 are repelled from each other, and the cigarette lifter 1 is located at the extraction position T.

[0111] So that the second magnet unit 21 and the third magnet unit 22 provided thereon can be switched between the first position D and the second position E, so that the cigarette lifter 1 can be switched between the attraction position F and the extraction position T, and the user can easily extract the aerosol generating article 3.

[0112] In some possible embodiments of the present application, referring to Figure 1 and Figure 2 , the outer circumferential side of the rotating member 51 is provided with an anti-skid structure 512. The friction between the user and the rotating member 51 is increased, and the user can easily push the rotating member 51 to rotate.

[0113] Exemplarily, the anti-skid structure 512 is at least one of a protruding point, a protruding line, and a protruding pattern.

[0114] Exemplarily, the protruding pattern can be a vertical pattern, an inclined pattern, or a combination of the vertical pattern and the inclined pattern. In the present embodiment, the anti-skid structure 512 is a vertical pattern.

[0115] In other possible embodiments of the present application, the anti-skid structure is not limited to this shape or this form.

[0116] Referring to Figure 3 and Figure 5 In some possible embodiments provided by the present application, the first magnet unit 11 includes two first magnets. The two first magnets are oppositely arranged along the radial direction R of the aerosol generating device 0. This makes the smoke lifting cylinder 1 uniformly stressed in the radial direction R, so that it moves more smoothly in the axial direction Z.

[0117] Referring to Figure 3 and Figure 4 In some possible embodiments provided by the present application, the second magnet unit 21 includes two second magnets. The two second magnets are oppositely arranged along the radial direction R of the aerosol generating device 0.

[0118] Referring to Figure 4 The third magnet unit 22 includes two third magnets. The two third magnets are oppositely arranged along the radial direction R. Each second magnet and each third magnet are arranged along the circumferential direction Q of the aerosol generating device 0. In this way, when the first position D is reached, the two second magnets are oppositely arranged along the axial direction Z with the two first magnets, or the two third magnets are oppositely arranged along the axial direction Z with the two first magnets, respectively.

[0119] Referring to Figure 3 and Figure 7 In some possible embodiments provided by the present application, the aerosol generating device 0 includes a top cover 03. The top cover 03 is used to close the upper surface of the aerosol generating device 0. The top cover 03 is provided with an insertion hole 04 for inserting the aerosol generating article 3. The insertion hole 04 and the smoke lifter 1 are oppositely arranged along the axial direction Z of the aerosol generating device 0, so that the aerosol generating article 3 inserted into the insertion hole 04 enters the smoke lifter 1.

[0120] Referring to Figure 7 The inner surface of the insertion hole 04 is provided with a corrugated structure 05, and the corrugated structure 05 forms an air inlet channel between the outer surface of the inserted aerosol generating article 3. As Figure 7 A cross-sectional view of the top cover of the aerosol generating device is shown. The corrugated structure 05 has an irregular shape, which has a substantially circular profile, and a plurality of rectangular protrusions are arranged on the circular profile, and the plurality of rectangular protrusions protrude along the radial direction of the circle center to the circle circumference, respectively.

[0121] Referring to Figure 8When the aerosol generating device 0 is in use, the airflow enters the gap of the corrugated structure 05, passes through the outer wall of the smoke riser 1, enters the inside of the aerosol generating article 3 through the hole 14 at the bottom of the smoke riser 1 (the hole 14 is used for inserting the heating body 4), and finally enters the user's oral cavity. Among them, when the airflow passes through the outer wall of the smoke riser 1, the aerosol generating device 0 preheats the air by using the heat dissipated by the outer wall of the smoke riser 1, thereby improving the heat utilization efficiency. At the same time, since the air is preheated, the fluctuation of the heating temperature is reduced, which is beneficial to improve the stability of the smoke.

[0122] With reference to Figure 3 In some possible embodiments provided by the present application, the top cover 03 and the shell of the aerosol generating device 0 are locked by threads.

[0123] In some other possible embodiments provided by the present application, the top cover 03 and the shell of the aerosol generating device 0 are matched by magnetic attraction, buckling or the like.

[0124] With reference to Figure 3 And Figure 7 In some other possible embodiments provided by the present application, the two guide piece mounting holes 06 are further provided on both sides of the insertion hole 04 of the top cover 03, and are used for mounting the guide piece 6.

[0125] In some other possible embodiments, the aerosol generating device 0 further comprises a plugging piece for the two guide piece mounting holes 06. After the guide piece 6 is mounted, the guide piece mounting hole 06 is covered by the plugging piece. The plugging piece and the guide piece mounting hole 06 can be connected by threads or buckling or the like. The present application does not limit the connection mode between the two.

[0126] In some possible embodiments provided by the present application, the aerosol generating device 0 further comprises a limiting piece (not shown in the figure) for limiting the relative sliding stroke of the sliding piece 7 and the guide piece 6.

[0127] The limiting piece is used for limiting the sliding piece 7. When the third magnet unit 22 is located at the first position D, the first magnet unit 11 repels the third magnet unit 22, so that the sliding piece 7 moves upward along the axial direction Z, and at the same time, the sliding piece 7 drives the smoke riser 1 to move upward along the axial direction Z, that is, to move along the Z1 direction. In order to prevent the sliding piece 7 and the smoke riser 1 from being pulled out of the aerosol generating device 0, it is necessary to set a limiting piece to limit the movement of the sliding piece 7. When the sliding piece 7 contacts the limiting piece, the sliding piece 7 will stop moving upward along the axial direction Z, thereby limiting the farthest movement distance of the sliding piece 7 along the axial direction Z.

[0128] In some possible embodiments, the limiting piece is arranged on the guide piece 6.

[0129] In some other possible embodiments, the aerosol-generating device 0 comprises a top cover 03 for covering the top of the aerosol-generating device 0, and the limiting member is arranged on the top cover 03.

[0130] With reference to Figure 6 In some possible embodiments of the present application, the cigarette lifter comprises two ear-shaped protrusions 81 arranged opposite to each other along the radial direction R of the aerosol-generating device 0. The limiting member comprises the ear-shaped protrusions 81 to prevent the cigarette lifter 1 from being separated from the body 2.

[0131] Specifically, in combination with Figure 3 and Figure 4 , the ear-shaped protrusions 81 can abut against the top cover 03 to limit the moving position of the cigarette lifter 1 and prevent the cigarette lifter 1 from being separated from the body 2. In this embodiment, the ear-shaped protrusions 81 have a limiting function. Specifically, when the cigarette lifter 1 moves to the lifting position T along the axial direction Z, the ear-shaped protrusions 81 can abut against the top cover 03 to prevent the cigarette lifter 1 from continuing to move upward along the axial direction Z.

[0132] With reference to Figure 6 , the ear-shaped protrusions 81 comprise the sliding member 7, the guide rail limiting channel 82 and the first magnet unit 11. The guide rail limiting channel 82 is used to limit the guide member 6 in the axial direction Z so that the guide member 6 is in contact with the sliding member 7 and guides the sliding member 7 to move along the guide member 6 in the axial direction Z.

[0133] With reference to Figure 6 , Figure 9 to Figure 11 , the shape of the guide rail limiting channel 82 is matched with the shape of the guide member 6. The guide member 6 can be inserted into the guide rail limiting channel 82, and the sliding member 7 arranged on the ear-shaped protrusion 81 is in contact with the guide member 6. The guide rail limiting channel 82 facilitates fixing the relative position of the sliding member 7 and the guide member 6. When the cigarette lifter 1 moves between the adsorption position F and the lifting position T, the sliding member 7, the guide rail limiting channel 82 and the first magnet unit 11 all move together with the axial direction Z movement of the cigarette lifter 1.

[0134] In this embodiment, with reference to Figure 9 , the surface of the guide member 6 in contact with the sliding member 7 is an arc surface, and the size thereof is matched with the size of the sliding member 7. The sliding member 7 can be placed in the guide member 6 and move along the guide member 6 in the axial direction Z.

[0135] Exemplarily, in this embodiment, with reference to Figure 9 , the cross-sectional shape of the guide member 6 is a first straight line 821, a second straight line 822, a third straight line 823, a fourth straight line 824, a fifth straight line 825 and a first arc line 826 connected in sequence. The radius of the first arc line 826 is equal to the radius of the sliding member 7. Figure 10 Figure 9 ​the view of the guide in the L view angle in the figure. Figure 11 for Figure 9 the view of the guide in the O view angle in the figure.

[0136] In some possible embodiments provided by the present application, when the third magnet unit 22 is located at the first position D, the repulsive force between the first magnet unit 11 and the third magnet unit 22 is equal to or greater than the gravity of the cigarette lifter 1 and the aerosol generating article 3 accommodated therein. This makes the cigarette lifter 1 stop moving to the lifting position T and cannot continue to move upward along the axial direction Z, that is, along the Z1 direction, that is, the cigarette lifter 1 is limited.

[0137] Generally, there are three main ways for heat dissipation, namely heat conduction, heat radiation and heat convection. In the aerosol generating device 0, heat conduction is the main heat transfer mode. The structure of the existing aerosol generating device 0 increases the heat conduction of the aerosol generating device 0, so that the surface temperature of the aerosol generating device 0 is relatively high, reducing the user experience. For example, in the IQOS product, the cigarette lifting structure needs to be connected to the shell through a transmission component, and the mass of the transmission component is large, increasing the heat load of the aerosol generating device 0. At the same time, due to the large connection area and contact area of the cigarette lifting structure, the transmission component and the shell, the heat conduction of the aerosol generating device 0 is increased. When too much heat is conducted to the surface of the aerosol generating device 0, if the surface temperature is too high, the user experience will be reduced.

[0138] To solve the problem of heat conduction of the aerosol generating device 0, the structure of the aerosol generating device 0 is further improved in the present application.

[0139] Reference Figure 3 In some possible embodiments provided by the present application, the driving assembly 5 and the cigarette lifter 1 are arranged along the axial direction Z of the aerosol generating device 0. This makes the cigarette lifter 1 not in direct contact with the driving assembly 5, that is, the cigarette lifter 1 and the driving assembly 5 are separated from each other, reducing the path of heat conduction, so that the surface temperature of the aerosol generating device 0 will not be too high, providing a good user experience.

[0140] Continuing to refer to Figure 3 The aerosol generating device 0 comprises a partition plate 9 arranged between the driving assembly 5 and the cigarette lifter 1, and the partition plate 9 divides the body 2 into a first partition space 91 and a second partition space 92. The first partition space 91 comprises the cigarette lifter 1. The second partition space 92 comprises the driving assembly 5. The partition plate 9 is used to prevent the smoke or condensate of the cigarette lifter 1 from entering the second partition space 92 from the first partition space 91. Preventing the condensate from entering the second partition space 92 from the first partition space 91 can effectively prevent the circuit board from being corroded by the condensate.

[0141] In some possible embodiments provided by the utility model, the cigarette lifter 1 is arranged separately from the driving assembly 5, and a cavity portion between the outer peripheral wall of the cigarette lifter 1 and the inner peripheral wall of the aerosol generating device 0 can be filled with a material such as aerogel for inhibiting heat convection heat transfer. This can effectively inhibit heat dissipation caused by heat convection.

[0142] In some possible embodiments provided by the utility model, the aerosol generating device 0 comprises a housing 01 and a top cover 03, and the baffle 9 is connected with the housing 01 or the top cover 03.

[0143] Reference Figure 3 In some possible embodiments provided by the utility model, in the aerosol generating device 0, the baffle 9 is connected with the housing 01.

[0144] In the embodiment, the aerosol generating device 0 comprises a heating body base, and the heating body 4 is arranged on the heating body base 41.
