Description

Technical Field

[0001] The present invention relates to the field of electronic smoking devices, and in particular to an aerosol generating device. Background Art

[0002] There are three main types of cigarette lifting structures used in aerosol generating devices on the market: users rotating cigarettes (i.e. aerosol generating products) to lift cigarettes, motor-assisted cigarette lifting, and IQOS-style mechanical cigarette lifting. Among them, IQOS is a heat-not-burn tobacco product launched by Philip Morris International. The name is the abbreviation of "INTELLIGENT QUITTING SMOKING SYSTEM", which literally means "intelligent smoking cessation system", but in fact it is not a smoking cessation tool, but a new type of aerosol generating device.

[0003] For an aerosol generating device provided with a circumferentially symmetrical heating body, the user can extract the aerosol generating product by rotating the aerosol generating product. When the user rotates the cigarette to extract the cigarette, the user pinches the cigarette holder and repeatedly rotates the cigarette clockwise and counterclockwise to separate the smoking substance from the heating body through the resistance between the smoking substances. However, this method of extracting the cigarette requires the user to learn it deliberately. In addition, when using the aerosol generating device, the user is likely to forget to rotate the cigarette and directly pull the cigarette out of the aerosol generating device, which causes the smoking substance to fall into the heating chamber, making it inconvenient for the user to use the aerosol generating device later.

[0004] In the IQOS product, the shell and the internal cigarette lifting structure are connected through a transmission component. When the user pushes upward on the shell, that is, the user applies an upward thrust on the shell, the shell will drive the internal cigarette lifting structure to move upward through the transmission component, so that the aerosol generating product in the cigarette lifting structure moves upward, thereby realizing the separation of the aerosol generating product from the heating body, and avoiding the adhesion of the smoking section in the aerosol generating product to the heating body, resulting in the smoking material being left inside the aerosol generating device. At present, many Chinese tobacco companies use similar cigarette lifting structures in their products. Although this cigarette lifting structure is simple. However, the cigarette lifting structure needs to be connected to the shell through a transmission component, and the mass of the transmission component is large, which increases the heat load of the aerosol generating device. At the same time, due to the large connection area and contact area between the cigarette lifting structure, the transmission component and the shell, the heat conduction of the aerosol generating device will be increased. When too much heat is conducted to the surface of the aerosol generating device, if its surface temperature is too high, the user experience will be reduced.

[0005] The principle of the motor-assisted cigarette lifting structure is similar to that of IQOS, except that it uses a motor to provide power for the cigarette lifting structure. The motor-assisted cigarette lifting structure converts the motor's rotational work into axial linear motion of the cigarette lifting structure. The motor-assisted cigarette lifting structure requires a motor to be provided and installed in the aerosol generating device, which not only increases the number of components and space occupied by 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 through a transmission structure such as a screw structure, which has a complex structural design and a high production cost, and the screw structure will increase the heat conduction of the aerosol generating device.

[0006] With the development of technology, an aerosol generating device with a cigarette lifting structure that adopts the principle of magnetic attraction has emerged. That is, the cigarette lifting structure and the body of the aerosol generating device are respectively provided with magnets that attract each other. When using the aerosol generating device, the cigarette lifting structure can be adsorbed and fixed on the body. When extracting the cigarette, a force greater than the adsorption force is used to release the adsorption of the cigarette lifting structure from the body. However, there are many problems with the aerosol generating device. If the magnetic attraction between the cigarette lifting structure and the body of the aerosol generating device is large, it will be very laborious to extract the cigarette lifting structure, which will cause a series of problems. For example, if the cigarette is suddenly extracted with great force, it is easy to cause the aerosol generating matrix in the smoking section of the cigarette to fall off and enter the interior of the aerosol generating device, which is not easy to clean and brings a bad user experience. If the magnetic attraction between the cigarette lifting structure and the body of the aerosol generating device is small, it is not convenient for users to use. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

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

[0041] In some possible embodiments provided by the present invention, reference is made to Figure 3 , Figure 4 Combined with Figure 1 and Figure 2 , an aerosol generating device 0 includes a cigarette holder 1 and a body 2.

[0042] The cigarette holder 1 is used to contain the aerosol generating product 3. The cigarette holder 1 is provided with a first magnet unit 11. For example, the cigarette holder 1 is as follows Figure 3 to Figure 4 A cigarette holder is shown.

[0043] The body 2 is provided with a driving assembly 5, and a second magnet unit 21 is provided on the driving assembly 5. The second magnet unit 21 is spaced apart from the first magnet unit 11 along the axial direction Z of the aerosol generating device 0. Figure 3 , Figure 4 Combined with Figure 5 , the movement of the driving assembly 5 can make the second magnet unit 21 move between the first position D and the second position E relative to the first magnet unit 11. 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 cigarette holder 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 de-adsorbed, so that the cigarette holder 1 and the body 2 are de-adsorbed and fixed.

[0044] In this embodiment, reference 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 attracted, and there is a large adsorption force between the cigarette holder 1 and the body 2, so that the cigarette holder 1 is stably adsorbed and fixed to the body 2, and it is difficult to extract the cigarette holder 1 and the aerosol generating product 3 therein. If brute force is used to extract, the aerosol generating matrix of the smoking section in the aerosol generating product 3 will fall into the heating chamber, which is difficult to clean and inconvenient for the user to use the aerosol generating device 0 later, giving the user a bad experience.

[0045] refer 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 released from adsorption, the adsorption force between the cigarette holder 1 and the main body 2 is weakened, and the main body 2 releases the adsorption and fixation of the cigarette holder 1, so it is easy to extract the cigarette holder 1 and the aerosol generating product 3 therein.

[0046] In the present invention, the driving component can move along the radial direction of the aerosol generating device, can also rotate along the circumferential direction of the aerosol generating device, and can also move along the axial direction of the aerosol generating device. The present invention does not limit this, as long as the movement of the driving component can make the second magnet unit move between the first position and the second position relative to the first magnet unit so that the cigarette holder is adsorbed and fixed to the body or released from adsorption and fixation.

[0047] In this embodiment, the driving assembly rotates along the circumference of the aerosol generating device to move the second magnet unit between the first position and the second position relative to the first magnet unit, so that the cigarette holder is fixed to or released from the body. Figure 5 , Figure 1 and Figure 2 The second magnet unit 21 is moved between the first position D and the second position E to realize the state conversion of the second magnet unit 21 and the first magnet unit 11 being mutually adsorbed and de-adsorbed, thereby realizing the state conversion of the aerosol generating product 3 being more firmly fixed in the cigarette holder 1 and being easy to be extracted from the cigarette holder 1. This makes the cigarette removing operation of the aerosol generating device 0 simple, convenient and quick, so that the user has a good experience.

[0048] In some other possible embodiments, the driving component moves along the axial direction of the aerosol generating device to move the second magnet unit between the first position and the second position relative to the first magnet unit, so that the cigarette holder is adsorbed and fixed to the body or released from adsorption and fixation. For example, the driving component is a toggle member, and the second magnet unit is provided on the toggle member. The toggle member can move axially. When the toggle member is lifted, the second magnet unit is located at the first position, and the second magnet unit and the first magnet unit are adsorbed to each other, so that the cigarette holder is adsorbed and fixed to the body. When the toggle member 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 adsorption, so that the cigarette holder is released from adsorption and fixation to the body.

[0049] By adopting the above technical solution, the first magnet unit 11 is arranged on the cigarette holder 1, and the second magnet unit 21 is arranged on the body 2. The first magnet unit 11 and the second magnet unit 21, which are not in direct contact, attract each other by their opposite poles, so that the cigarette holder 1 moves relative to the body 2 to extract the aerosol generating product 3. The aerosol generating device 0 omits the transmission structure, making the connection structure simple and reducing the number of parts.

[0050] In the first embodiment of the present invention, the first magnet unit includes sub-magnet 1 and sub-magnet 2, and sub-magnet 1 and sub-magnet 2 are arranged opposite to each other along the radial direction of the aerosol generating device 0. The second magnet unit includes sub-magnet 3 and sub-magnet 4, and sub-magnet 3 and sub-magnet 4 are arranged opposite to each other along the radial direction of the aerosol generating device 0.

[0051] When the second magnet unit is in the first position, sub-magnet 1 and sub-magnet 3 are arranged opposite to each other and attract each other, sub-magnet 2 and sub-magnet 4 are arranged opposite to each other and attract each other, so that the cigarette holder 1 is adsorbed and fixed on the body. When the second magnet unit is in the second position, sub-magnet 1 and sub-magnet 4 are arranged opposite to each other and repel each other, sub-magnet 2 and sub-magnet 2 are arranged opposite to each other and repel each other, so that the cigarette holder is repelled in the body. The second magnet unit in the first position can be rotated 180° along the circumferential direction to reach the second position.

[0052] By changing the relative positions of sub-magnet 1, sub-magnet 2, sub-magnet 3 and sub-magnet 4, the adsorption and repulsion states of the first magnet unit and the second magnet unit are changed, thereby achieving adsorption and repulsion between the cigarette holder and the body. When the cigarette holder and the body are adsorbed, the cigarette holder is stably fixed and adsorbed in the body, which facilitates the insertion of the aerosol generating product. When the cigarette holder and the body are repelled, the cigarette holder is easily extracted from the body. Furthermore, when the cigarette holder and the body are repelled, the cigarette holder is subjected to a large repulsive force, so that the cigarette holder and the aerosol generating product located therein move upward along the axial direction of the aerosol generating device, thereby achieving the extraction of the aerosol generating product.

[0053] In the second embodiment of the present invention, reference Figure 5 Combined with Figures 1 to 3 The driving assembly 5 is provided with a third magnet unit 22 .

[0054] In some possible embodiments, the second magnet unit and the third magnet unit can be moved synchronously by moving a component in the driving assembly 5. Figure 5 The driving assembly 5 includes a rotating member, on which a second magnet unit 21 and a third magnet unit 22 are provided. The second magnet unit 21 includes two second magnets. The two second magnets 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. The two third magnets are arranged opposite to each other along the radial direction R. Each second magnet and each third magnet are arranged at intervals 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, the synchronous movement of the second magnet unit 21 and the third magnet unit 22 can be achieved by rotating the rotating member.

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

[0056] Regardless of whether the same component in the driving assembly 5 drives the second magnet unit and the third magnet unit to achieve synchronous movement or different components in the driving assembly 5 drive the second magnet unit and the third magnet unit to move respectively. In short, the movement of the driving assembly 5 can make the third magnet unit 22 move between the first position D and the third position (not shown in the figure) relative to the first magnet unit 11. 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 holder 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 holder 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 holder 1 is repelled in the body 2 and the cigarette holder 1 is easily extracted from the body 2 .

[0058] In this 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 holder 1 and the aerosol generating product 3 located therein move upward along the axial direction Z of the aerosol generating device 0 under the action of the repulsive force, that is, move along the Z1 direction (such as Figure 2 As shown), that is, it moves in a direction away from the aerosol generating device 0, so that the aerosol generating product 3 is out of a position where it can be heated and inhaled normally, thereby realizing the extraction of the aerosol generating product 3.

[0059] By moving the third magnet unit 22 between the first position D and the third position, the third magnet unit 22 and the first magnet unit 11 can be switched to a state of mutual repulsion and elimination of repulsion. By utilizing the principle that like poles repel each other, the aerosol generating product 3 can be extracted by utilizing the third magnet unit 22 and the first magnet unit 11. There is no need for the user to manually extract the aerosol generating product 3, which makes the cigarette extraction operation of the aerosol generating device 0 simpler, more convenient, and faster, giving the user a better experience.

[0060] In some possible embodiments provided by the present invention, reference is made 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 offset from the first magnet unit 11 along the axial direction Z.

[0061] refer to Figure 3 When the second magnet unit 21 is located at the first position D, the second magnet unit 21 is opposite to the first magnet unit 11 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 holder 1 is firmly 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 and the first magnet unit 11 are offset along the axial direction Z of the aerosol generating device 0, the adsorption force between the second magnet unit 21 and the first magnet unit 11 is weakened, and the adsorption force between the cigarette holder 1 and the main body 2 is weakened, which facilitates the extraction of the cigarette holder 1 and the aerosol generating product 3 located therein.

[0063] In some possible embodiments of the present invention, 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 offset from 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 and the first magnet unit 11 are opposite to each other 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 holder 1 is repelled in the body 2, and the cigarette holder 1 is easily extracted. Furthermore, when the repulsive force between the third magnet unit 22 and the first magnet unit 11 is the largest, and the repulsive force is equal to or greater than the gravity of the cigarette holder 1 and the aerosol generating product 3 located therein, the cigarette holder 1 can move upward along the axial direction Z of the aerosol generating device 0, that is, move along the Z1 direction, under the action of the repulsive force, to achieve extraction of the aerosol generating product 3.

[0065] When the third magnet unit 22 is located at the third position, the third magnet unit 22 and the first magnet unit 11 are offset 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, the repulsive force between the cigarette holder 1 and the body 2 is weakened, and the cigarette holder 1 can move a limited distance upward along the axial direction Z of the aerosol generating device 0. 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 holder 1 and the body 2, and the cigarette holder 1 will not be displaced along the axial direction Z of the aerosol generating device 0.

[0066] As mentioned earlier, Figure 5 The second magnet unit 21 and the third magnet unit 22 are both arranged on the rotating member, and the second magnet unit 21 and the third magnet unit 22 can be synchronously moved by rotating the rotating member. Figure 3 , Figure 4 and Figure 5 , 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 arranged opposite to each other along the axial direction Z of the aerosol generating device 0, and the third magnet unit 22 and the first magnet unit 11 are staggered along the axial direction Z. When the third magnet unit 22 is located at the first position D, the third magnet unit 22 and the first magnet unit 11 are arranged opposite to each other along the axial direction Z of the aerosol generating device 0, and the second magnet unit 21 and the first magnet unit 11 are staggered along the axial direction Z. That is to say, in fact, the first magnet unit 11 and the second magnet unit 21 are arranged at intervals along the axial direction Z; the first magnet unit 11 and the third magnet unit 22 are arranged at intervals along the axial direction Z.

[0067] In some possible embodiments provided by the present invention, reference is made to Figure 5 Combined 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 toggle member or a rotating member.

[0069] The driving assembly 5 comprises a rotating member 51 which can rotate 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 on the rotating member 51 at intervals along the circumferential direction Q and can rotate with the rotation of the rotating member 51.

[0070] For example, the rotating member is in an "X" shape, or in a "+" shape. Preferably, the rotating member 51 is a rotating disk.

[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; 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] refer to Figures 3 to 5 The second magnet unit 21 and the third magnet unit 22 are arranged on the rotating member 51, and the two move between the first position D and the second position E with the rotation of the rotating member 51, so as to skillfully realize the switching between the state of mutual attraction and mutual repulsion between the cigarette holder 1 and the body 2, so that the cigarette holder 1 moves along the axial direction Z, especially when the cigarette holder 1 moves upward along the axial direction Z, the aerosol generating product 3 can be quickly and conveniently extracted. At the same time, the aerosol generating device 0 has a simple structural design, which reduces the production cost.

[0073] In some possible embodiments provided by the present invention, reference is made to Figure 3 and 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 matches the shape of the heating body 4 so that the heating body 4 can pass through the hole 14. For example, if the heating body 4 is a heating needle, the hole 14 is circular; for another example, if the heating body 4 is a sheet, the hole 14 is rectangular. The present invention does not limit the shape of the heating body 4 and the hole 14, as long as the shape of the hole 14 matches the shape of the heating body 4 and the heating body 4 can pass through the hole 14.

[0075] Compared with the method of users rotating cigarettes (i.e., aerosol generating products 3) to extract cigarettes, the aerosol generating device 0 provided by the present invention does not need to rotate the aerosol generating products 3 along the circumferential direction Q. Only by cooperating with different magnet units, the cigarette extractor 1 and the aerosol generating products 3 therein can be moved along the axial direction Z to extract the aerosol generating products 3. Therefore, the aerosol generating device 0 provided by the present invention is not limited to being used in an aerosol generating device 0 provided with a heating body 4 that is symmetrical in the circumferential direction Q, but can also be used in an aerosol generating device 0 provided with an asymmetric heating body 4.

[0076] In some possible embodiments provided by the present invention, reference is made to Figures 1 to 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. Figure 1 , at the adsorption position F, the aerosol generating article 3 located in the cigarette holder 1 is embedded in the body 2. Figure 2 At the extraction position T, the aerosol generating product 3 located in the cigarette holder 1 is more exposed from the body 2 than at the adsorption position F. Figure 3 and Figure 5 When the second magnet unit 21 is located at the first position D, the cigarette holder 1 is attracted 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 this embodiment, the adsorption position F of the cigarette extractor 1 is located below its extraction position T along the axial direction Z. The cigarette extractor 1 located at the adsorption position F can move upward along the axial direction Z to reach the cigarette extraction position T. Figures 1 to 5 When the second magnet unit 21 is located at the first position D, the cigarette holder 1 is attracted and moved to the adsorption position F. At the adsorption position F, the aerosol generating product 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 moved to the extraction position T, so that the aerosol generating product 3 can be extracted.

[0078] In this embodiment, reference Figure 3 The adsorption position F is the position where the aerosol generating article 3 in the cigarette holder 1 can be heated and inhaled normally. It is also the position where the aerosol generating article 3 can be inserted into the cigarette holder 1 in place.

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

[0080] The extraction position T is the position where the cigarette holder 1 is separated from the aerosol generating product 3 and can be normally heated and smoked. Figure 4 The extraction position T shown is also the position of the aerosol-generating article 3 when it is extracted from the cigarette holder 1 .

[0081] Specifically, the aerosol generating product 3 is extracted from the cigarette holder 1 , which means that the aerosol generating product 3 moves upward along the axial direction Z of the aerosol generating device 0 or toward the outside of the aerosol generating device 0 , and the heating body 4 is separated from the aerosol generating product 3 .

[0082] Continue to refer Figure 3 and Figure 4 In some possible embodiments provided by the present invention, the aerosol generating device 0 further includes a guide 6 and a slide 7. One of the guide 6 and the slide 7 is disposed on the body 2, and the other is disposed on the cigarette dispenser 1. Through the cooperation of the guide 6 and the slide 7, the cigarette dispenser 1 moves between the adsorption position F and the extraction position T.

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

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

[0085] In this embodiment, the cigarette holder 1 is moved between the adsorption position F and the extraction position T by the rolling friction between the guide member 6 and the sliding member 7. The rolling friction effectively reduces the movement resistance of the cigarette holder 1.

[0086] In some possible embodiments of the present invention, the sliding member 7 is spherical. In other words, the sliding member 7 is a ball. The sliding member 7 is preferably made of non-polar materials, such as PA (polyamide), PC (polycarbonate), PEEK (polyetheretherketone), etc. In some possible embodiments, the guide member 6 is preferably made of a rigid non-polar material, avoiding the use of materials with good thermal conductivity as the guide member 6 material, thereby reducing the heat conduction of the aerosol generating device 0.

[0087] refer to Figure 3 and Figure 5 In some possible embodiments provided by the present invention, the aerosol generating device 0 includes a limiting structure for limiting the rotation angle of the rotating member 51 .

[0088] Exemplarily, the limiting structure may include a groove 02 arranged on the shell 01 and a stop member (such as a toggle stop member) on the rotating member 51. The width of the groove 02 (that is, the circumferential dimension of the groove 02) can limit the stroke of the stop member, thereby limiting the circumferential movement of the rotating member 51.

[0089] Alternative, reference Figure 5 The driving assembly 5 includes a fixed shaft 52 , and the limiting structure includes a limiting portion 521 provided on the fixed shaft 52 and a stopper 511 provided on the rotating member 51 .

[0090] The limiting portion 521 is protruded from the fixed shaft 52 along 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 along the circumferential direction Q around the fixed shaft 52.

[0091] The stopper 511 is protruded from the rotating member 51 along the radial direction R. The stopper 521 cooperates with the stopper 511 to prevent the stopper 511 from continuing to move, and limits the rotating member 51 to rotate at a predetermined angle.

[0092] like Figure 5 As shown, the rotating member 51 is an annular structure. The rotating member 51 includes a sleeve member 53, which is used to sleeve 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 a stopper 511, which protrudes from the rotating member 51 along the radial direction R. One end of the stopper 511 is connected to the sleeve member 53, and the other end is connected to the rotating member 51.

[0093] For example, Figure 5As shown, the rotating member 51 is provided with two stops, namely, a first stop 511A and a second stop 511B. The first stop 511A and the second stop 511B are arranged opposite to each other along the radial direction R. A stopper 521 is protrudingly provided on the fixed shaft 52 along the radial direction R. The initial position is that the first stopper 511A contacts the stopper 521. When the rotating member 51 is rotated 180° clockwise, the stopper 521 blocks the second stopper 511B from continuing to move clockwise. In this embodiment, the stopper 521 cooperates with the stopper to limit the predetermined angle of rotation of the rotating member 51 to 180°.

[0094] In some possible embodiments provided by the present invention, Figure 5 As shown, the second magnet unit 21 and the third magnet unit 22 are arranged at intervals on the rotating member 51 along the circumferential direction Q. The second magnet unit 21 includes two second magnets. The third magnet unit 22 includes two third magnets. Along the circumferential direction Q, each second magnet and each third magnet are arranged at intervals on the rotating member 51.

[0095] refer to Figures 3 to 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 holder 1 is located at the adsorption position F, and the aerosol generating product 3 can be inserted in place. The rotating member 51 is rotated 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 and the first magnet unit 11 are repelled, so that the cigarette holder 1 moves upward along the axial direction Z until the cigarette holder 1 is located at the cigarette holding position, so as to facilitate the extraction of the aerosol generating product 3.

[0096] In some other possible embodiments, the rotating member 51 is provided with two stops, namely, a third stopper and a fourth stopper (not shown in the figure). The third stopper and the fourth stopper are protruding from the rotating member 51 along the radial direction R. The third stopper and the fourth stopper are 90° apart. The initial position is that the third stopper contacts the limiting portion 521. When the rotating member 51 is rotated 90° clockwise, the limiting portion 521 blocks the third stopper from continuing to move clockwise. The limiting portion 521 cooperates with the stopper 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 present invention, it is possible to set the positions of the limiting portion 521 and the stopper 511 to limit the predetermined angle of rotation of the rotating member 51 according to actual needs and specific circumstances, and the present invention does not limit this. In some other possible embodiments, in the aerosol generating device 0 provided by the present invention, the limiting structure of the predetermined angle of the rotating member 51 is not limited to the form of the limiting portion 521 and the stopper 511 provided in this embodiment, and the present invention does not limit this, as long as it can realize the rotation of the rotating member 51 by a predetermined angle.

[0098] Exemplarily, the position-limiting structure of the predetermined angle of the rotating member 51 can be in the form of concave-convex matching, for example, a protrusion is provided on the outer surface of the fixed shaft 52, and a concave portion is provided on the inner surface of the sleeve 53, and the predetermined angle of rotation of the rotating member 51 is limited by the concave-convex matching. Alternatively, a concave portion is provided on the outer surface of the fixed shaft 52, and a protrusion is provided on the inner surface of the sleeve 53, and the predetermined angle of rotation of the rotating member 51 is limited by the concave-convex matching. The position-limiting structure of the predetermined angle of the rotating member 51 can also be in the form of a snap-fit, for example, a snap-fitting member is provided on the outer surface of the fixed shaft 52, and a coupling member is provided on the inner surface of the sleeve 53, and the predetermined angle of rotation of the rotating member 51 is limited by the snap-fit. Alternatively, a coupling member is provided on the outer surface of the fixed shaft 52, and a snap-fitting member is provided on the inner surface of the sleeve 53, and the predetermined angle of rotation of the rotating member 51 is limited by the snap-fit.

[0099] In some other possible embodiments, the fixed shaft is provided with a limiting portion. The limiting portion is provided on the fixed shaft and protrudes in the radial direction of the aerosol generating device, and the limiting portion extends in the axial direction. Figure 5 The driving assembly shown is a hollow part except for the sleeve, the stopper, the rotating member 51, and the second magnet unit 21 and the third magnet unit 22 arranged on the rotating member 51. In other words, the space formed by the sleeve 53, the stopper and the inner side of the rotating member are all hollow parts. The limiting part is arranged to be a structure protruding in the radial direction R and extending in the axial direction Z, and the part extending in the axial direction thereof extends into the aforementioned hollow part. In this way, the part extending in the axial direction of the limiting part can contact with the stopper, and it is blocked by the stopper and no longer moves in the circumferential direction. This arrangement can also enable the limiting part to cooperate with the stopper to limit the rotating member to rotate by a predetermined angle.

[0100] In some other possible embodiments, the driving assembly 5 includes a rotating shaft. The rotating member 51 rotates with the rotation of the rotating shaft. A limiting portion is provided on the fixed structure of the rotating shaft. The limiting portion protrudes radially from the aerosol generating device 0 and is provided on the fixed structure of the rotating shaft. The rotating member 51 is sleeved on the rotating shaft. The rotating member 51 is provided with a stopper, which protrudes radially from the rotating member 51. The limiting portion cooperates with the stopper to prevent the stopper from continuing to move, and limits the rotating member 51 to rotate a predetermined angle.

[0101] refer to Figure 5 In this embodiment, the rotating member 5 is a ring-shaped symmetrical structure with a hollow center, which reduces the mass of the rotating member 5 and also reduces the mass of the aerosol generating device 0.

[0102] In some possible embodiments provided by the present invention, the aerosol generating device 0 includes an elastic member (not shown in the figure) for assisting the cigarette holder 1 to return to the adsorption position F from the extraction position T.

[0103] One end of the elastic member is connected to the rotating member 51 , and the other end is connected to the non-moving component. 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 may be a spring, a torsion spring, or an elastic sheet.

[0105] In this embodiment, after the user lets go, the rotating member 51 can automatically reset to the second magnet unit 21 at the first position D, so that the cigarette holder 1 is adsorbed by the body 2, and the cigarette holder 1 is reset to the adsorption position F. Therefore, the provision of the elastic member enables the cigarette holder 1 to automatically return from the extraction position T to the adsorption position F, thereby realizing the automation of the aerosol generating device 0 and facilitating the use of the user.

[0106] refer to Figure 1 and Figure 2 Combined with Figure 3 and Figure 5 In some possible embodiments provided by the present invention, the aerosol generating device 0 includes a housing 01. A slot 02 is provided on the housing 01. The outer peripheral side of the rotating member 51 is exposed from the slot 02, so that the outer peripheral side of the rotating member 51 can be driven to cause the rotating member 51 to rotate, thereby enabling the second magnet unit 21 and / or the third magnet unit 22 to be respectively placed in the first position D as the rotating member 51 rotates.

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

[0108] Preferably, if Figure 1 and Figure 2 As shown, the outer peripheral side 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, a second magnet unit is provided on the rotating member. The outer peripheral side of the rotating member is exposed from the groove, and the user can directly contact the rotating member and push the rotating member to rotate, thereby switching the second magnet unit provided thereon 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 mutually adsorbed, so that the cigarette holder and the body are adsorbed and fixed; when the second magnet unit is located at the second position, the second magnet unit and the first magnet unit are de-adsorbed, so that the cigarette holder and the body are de-adsorbed and fixed.

[0110] In some other possible embodiments, refer 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 evenly spaced along the circumferential direction Q of the rotating member 51. 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, so that the second magnet unit 21 and the third magnet unit 22 can be respectively placed in the first position D as the rotating member 51 rotates. 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 the second magnet unit 21 and the first magnet unit 11 are mutually attracted, so that the cigarette holder 1 and the body 2 are attracted and fixed, and the cigarette holder 1 is located at the adsorption 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 repel each other, so that the cigarette holder 1 and the body 2 repel each other, and the cigarette holder 1 is located at the extraction position T.

[0111] Thereby, the second magnet unit 21 and the third magnet unit 22 arranged thereon can be switched between the first position D and the second position E respectively, so that the cigarette holder 1 can be switched between the adsorption position F and the extraction position T, which is convenient for the user to extract the aerosol generating product 3.

[0112] In some possible embodiments provided by the present invention, reference is made to Figure 1 and Figure 2 The outer peripheral side of the rotating member 51 is provided with an anti-slip structure 512. The friction between the user and the rotating member 51 is increased, making it easier for the user to push the rotating member 51 to rotate.

[0113] Exemplarily, the anti-slip structure 512 is at least one of a convex point, a convex strip, and a convex pattern.

[0114] Exemplarily, the convex pattern can be a vertical pattern, a diagonal pattern, or a combination of the vertical pattern and the diagonal pattern. In this embodiment, the anti-slip structure 512 is a vertical pattern.

[0115] In some other possible embodiments provided by the present invention, the anti-slip structure is not limited to this shape or form.

[0116] refer to Figure 3 and Figure 5 In some possible embodiments provided by the present invention, the first magnet unit 11 includes two first magnets. The two first magnets are arranged opposite to each other along the radial direction R of the aerosol generating device 0. This makes the cigarette holder 1 evenly stressed in the radial direction R, making it move more smoothly along the axial direction Z.

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

[0118] refer to Figure 4 The third magnet unit 22 includes two third magnets. The two third magnets are arranged opposite to each other in the radial direction R. Each second magnet and each third magnet are arranged at intervals along the circumferential direction Q of the aerosol generating device 0. This arrangement realizes that in the first position D, the two second magnets are arranged opposite to the two first magnets along the axial direction Z, or the two third magnets are arranged opposite to the two first magnets along the axial direction Z respectively.

[0119] refer to Figure 3 and Figure 7 In some possible embodiments provided by the present invention, the aerosol generating device 0 includes a top cover 03. The top cover 03 is used to seal 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 product 3. The insertion hole 04 and the cigarette holder 1 are arranged with a relative spacing along the axial direction Z of the aerosol generating device 0, so that the aerosol generating product 3 enters the cigarette holder 1 after being inserted into the insertion hole 04.

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

[0121] refer to Figure 8 When inhaling, the airflow enters the aerosol generating device 0 from the gap of the corrugated structure 05, passes through the outer wall of the cigarette holder 1, and enters the interior of the aerosol generating product 3 through the hole 14 at the bottom of the cigarette holder 1 (the hole 14 is used to insert the heating body 4), and finally enters the user's mouth. When the airflow passes through the outer wall of the cigarette holder 1, the aerosol generating device 0 uses the heat dissipated from the outer wall of the cigarette holder 1 to preheat the air, 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 improving the stability of smoke output.

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

[0123] In some other possible embodiments provided by the present invention, the top cover 03 and the outer shell of the aerosol generating device 0 are matched with each other by means of magnetic attraction, snap fastening, etc.

[0124] refer to Figure 3 and Figure 7In some other possible embodiments provided by the present invention, two guide member installation holes 06 are further provided on both sides of the insertion hole 04 of the top cover 03 for installing the guide member 6.

[0125] In some other possible embodiments, the aerosol generating device 0 further includes two blocking members for the guide member installation holes 06. After the guide member 6 is installed, the blocking member covers the guide member installation hole 06. The blocking member and the guide member installation hole 06 may be connected by a threaded connection or a snap connection, etc. The present invention does not limit the connection method between the two.

[0126] In some possible embodiments provided by the present invention, the aerosol generating device 0 further includes a limiter (not shown in the figure) to limit the relative sliding stroke of the sliding member 7 and the guiding member 6 .

[0127] The limiter is used to limit the sliding member 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 member 7 moves upward along the axial direction Z, and at the same time, the sliding member 7 drives the cigarette holder 1 to move upward along the axial direction Z, that is, along the Z1 direction. In order to prevent the sliding member 7 and the cigarette holder 1 from escaping from the aerosol generating device 0, it is necessary to set a limiter to limit the movement of the sliding member 7. When the sliding member 7 contacts the limiter, the sliding member 7 will stop moving upward along the axial direction Z, thereby limiting the maximum movement distance of the sliding member 7 in the axial direction Z.

[0128] In some possible embodiments, the limiting member is disposed on the guiding member 6 .

[0129] In some other possible embodiments, the aerosol generating device 0 includes a top cover 03 , which is used to cover the top of the aerosol generating device 0 , and the limiting member is disposed on the top cover 03 .

[0130] refer to Figure 6 In some possible embodiments provided by the present invention, the cigarette holder includes two ear-shaped protrusions 81, and the two ear-shaped protrusions 81 are arranged opposite to each other along the radial direction R of the aerosol generating device 0. The limiting member includes the ear-shaped protrusions 81 to prevent the cigarette holder 1 from being separated from the body 2.

[0131] Specifically, combined Figure 3 and Figure 4 The ear-shaped protrusion 81 can abut against the top cover 03 to limit the moving position of the cigarette holder 1 and prevent the cigarette holder 1 from being separated from the body 2. In this embodiment, the ear-shaped protrusion 81 has a limiting function. Specifically, when the cigarette holder 1 moves along the axial direction Z to the extraction position T, the ear-shaped protrusion 81 can abut against the top cover 03 to prevent the cigarette holder 1 from continuing to move upward along the axial direction Z.

[0132] refer to Figure 6The ear-shaped protrusion 81 includes a sliding member 7, a guide rail limiting channel 82 and a 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 contacts the sliding member 7 and guides the sliding member 7 to move in the axial direction Z along the guide member 6.

[0133] refer to Figure 6 , Figures 9 to 11 The shape of the guide rail limiting channel 82 matches 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 provided on the ear-shaped protrusion 81 contacts the guide member 6. The guide rail limiting channel 82 is convenient for fixing the relative position of the sliding member 7 and the guide member 6. When the cigarette holder 1 moves between the adsorption position F and the extraction position T, the sliding member 7, the guide rail limiting channel 82 and the first magnet unit 11 will move together with the axial Z movement of the cigarette holder 1.

[0134] In this embodiment, reference Fig. 9 The surface where the guide 6 contacts the sliding member 7 is an arc-shaped surface, and its size is adapted to the size of the sliding member 7. The sliding member 7 can be placed in the guide 6 and move along the guide 6 in the axial direction Z.

[0135] For example, in this embodiment, reference Fig. 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 which are connected in sequence. The radius of the first arc line 826 is equal to the radius of the sliding member 7. Fig.10 for Fig. 9 A view of the guide in L perspective. Fig.11 for Fig. 9 View of the guide in O perspective.

[0136] In some possible embodiments provided by the present invention, 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 holder 1 and the aerosol generating product 3 contained therein. This makes the cigarette holder 1 stop when it moves to the extraction position T, and does not continue to move upward along the axial direction Z, that is, along the Z1 direction, which means that the cigarette holder 1 has a limiting effect.

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

[0138] In order to solve the heat conduction problem of the aerosol generating device 0 , the present invention further improves the structure of the aerosol generating device 0 .

[0139] refer to Figure 3 In some possible embodiments provided by the present invention, the driving assembly 5 and the cigarette holder 1 are spaced apart along the axial direction Z of the aerosol generating device 0. This prevents the cigarette holder 1 from directly contacting the driving assembly 5, that is, the cigarette holder 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 for the user.

[0140] Continue to refer Figure 3 The aerosol generating device 0 includes a partition 9, which is disposed between the driving assembly 5 and the cigarette holder 1. The partition 9 divides the body 2 into a first partition space 91 and a second partition space 92. The first partition space 91 includes the cigarette holder 1. The second partition space 92 includes the driving assembly 5. The partition 9 is used to prevent smoke or condensate of the cigarette holder 1 from entering the second partition space 92 from the first partition space 91. Preventing 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 present invention, the cigarette holder 1 is separated from the driving assembly 5, and the cavity between the outer peripheral wall of the cigarette holder 1 and the inner peripheral wall of the aerosol generating device 0 can be filled with a material such as aerogel that inhibits heat transfer by thermal convection. This can effectively inhibit the heat dissipation caused by thermal convection.

[0142] In some possible embodiments provided by the present invention, the aerosol generating device 0 includes a shell 01 and a top cover 03 , and the partition 9 is connected to the shell 01 or the partition 9 is connected to the top cover 03 .

[0143] refer to Figure 3 In some possible embodiments provided by the present invention, in the aerosol generating device 0 , the partition 9 is connected to the shell 01 .

[0144] In this embodiment, the aerosol generating device 0 includes a heating body base, and the heating body 4 is arranged on the heating body base 41. The heating body base 41 is arranged on the partition 9, and the partition 9 is used to support the heating body base 41. In this embodiment, the heat conduction path of the heating body 4 is mainly conducted from the heating body base 41 to the housing 01 of the aerosol generating device 0 through the partition 9.
