DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0046] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] In the related technologies of aerosol generating systems, in order to enable a single aerosol generating product to achieve the purpose of multiple puffs, the cross-section of the aerosol generating product is usually designed to be circular, and the aerosol generating product can rotate relative to the aerosol generating device. However, in this solution, during the user experience, it can be seen that the aerosol generating product rotates, which is quite different from the solution in which the aerosol generating product does not rotate during the user's traditional puffing process. Some users may not be suitable for this aerosol generating system.

[0048] Based on this, an embodiment of the present application provides an aerosol generating system. The aerosol generating system can achieve the purpose of multiple puffs of a single aerosol generating product by rotating a heating component for heating the aerosol generating product relative to the aerosol generating product, and does not require the aerosol generating product to rotate. This solves the problem of the existing aerosol generating system that, during the user experience, the user can see that the aerosol generating product rotates, which is quite different from the solution in which the aerosol generating product does not rotate during the user's traditional puffing process, and some users may not be suitable for this aerosol generating system.

[0049] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0050] See also Figure 1 , Figure 1 It is a schematic diagram of the internal structure of an aerosol generating system provided in one embodiment of the present application. Figure 2 is a cross-sectional view taken along line AA of an aerosol generating system provided by an embodiment of the present application; Figure 3 yes Figure 2 In this embodiment, an aerosol generating system is provided. The aerosol generating system includes an aerosol generating article 1 and an aerosol generating device 2.

[0051] The aerosol generating product 1 is packaged as an atomizing medium, including an aerosol generating matrix, and the aerosol generating matrix is ​​partially or entirely used to form an aerosol when the temperature is raised to 200-500°C. The aerosol generating matrix can be a solid matrix, which can include one or more of powders, particles, fragments, strips or flakes of one or more plant leaves such as tobacco, vanilla leaves, tea leaves, mint leaves, etc.; or, the solid matrix can contain additional volatile aroma compounds to be released when the matrix is ​​heated. Of course, the aerosol generating matrix may also include a liquid matrix or a paste matrix, such as oils with added aroma components, liquid medicine, etc. The specific structure and function of the aerosol generating product 1 can be referred to the existing aerosol generating products, which will not be repeated here.

[0052] The aerosol generating device 2 is used to heat the aerosol generating product 1 to form an aerosol for the user to inhale. The specific structure and function of the aerosol generating device 2 can refer to the relevant description of the aerosol generating device 2 in the following embodiment.

[0053] Combination Figure 2 and Figure 3 In this embodiment, an aerosol generating device 2 is provided. The aerosol generating device 2 includes a shell assembly and a laser module 25. The shell assembly has a receiving chamber 21, and the aerosol generating product 1 is received in the receiving chamber 21. The laser module 25 is disposed on one side of the receiving chamber 21, and is used to emit a laser to heat the aerosol generating product 1 in the receiving chamber 21. In a specific embodiment, the laser module 25 is configured to be able to rotate around the receiving chamber 21, so as to heat the aerosol generating product 1 in the receiving chamber 21 from different directions along the circumferential direction of the aerosol generating product 1, and uniformly form an aerosol. Among them, the cross-section of the receiving chamber 21 at any position along the depth direction thereof is a central axis symmetrical figure; the laser module 25 can be specifically configured to rotate around the central axis M of the receiving chamber 21; the present application takes the cylindrical receiving chamber 21 as an example for explanation. Of course, it can be understood that the accommodating cavity 21 can also be an irregular cavity structure; in this case, the laser module 25 can be specifically configured to rotate around the axis of rotation, with the axis where the center of the circle with the maximum diameter within the figure where the cross section of the accommodating cavity 21 is located being the rotation axis.

[0054] The laser module 25 used to heat the aerosol generating product 1 is configured to be rotatable around the central axis M of the accommodating chamber 21, which not only ensures that each position of the aerosol generating product 1 along its circumferential direction can be uniformly heated and atomized to improve the utilization rate of the aerosol generating product 1, thereby increasing the number of puffs of the aerosol generating product 1; but also does not require the aerosol generating product 1 to be rotated, which matches the user's traditional non-rotating aerosol generating product puffing scheme and has better adaptability.

[0055] like Figure 3 As shown, the shell assembly includes a shell 20 and a heat sink 23 disposed in the shell 20. The heat sink 23 is used to absorb waste heat when the laser module 25 is working, and at the same time fix, support and drive the laser module 25 to rotate. Specifically, the heat sink 23 is a hollow cylindrical structure, and the hollow structure inside the heat sink 23 forms a receiving chamber 21. The aerosol generating product 1 is accommodated in the receiving chamber 21. The heat sink 23 is configured to be able to rotate relative to the shell 20 around the central axis M of the receiving chamber 21. The laser module 25 is disposed inside the side wall of the heat sink 23 and is configured to be able to rotate with the heat sink 23; so as to heat the aerosol generating product 1 in the receiving chamber 21 from different directions. Specifically, the heat sink 23 can be a hollow cylinder; of course, it can also be a hollow prism. The heat sink 23 can specifically be a heat sink.

[0056] By making the heat sink 23 rotate relative to the housing 20, the laser module 25 rotates along with the heat sink 23; thus, not only can the laser module 25 rotate relative to the central axis M of the accommodating chamber 21, but also the housing 20 and the aerosol generating product 1 can be kept relatively still; thus, when the user uses the aerosol generating device 2, the aerosol generating product 1 and the aerosol generating device 2 seen by the user are relatively still, which is similar to the traditional suction scheme and has better applicability.

[0057] In some embodiments, see Figures 4 to 5 , Figure 4 is a schematic diagram of the overall structure of the heat sink; Figure 5 for Figure 4 The inner surface of the heat sink 23, that is, the inner surface of the side wall of the accommodating cavity 21, has a groove 231, and the laser module 25 is specifically arranged in the groove 231. In this way, the groove 231 can be used to protect the laser module 25.

[0058] Specifically, the groove 231 extends along the central axis direction Y of the accommodating chamber 21, and the length of the groove 231 is greater than the length of the laser module 25, the width of the groove 231 is greater than the transverse width of the laser module 25, and the depth of the groove 231 is greater than the thickness of the laser module; to ensure that the laser module 25 is entirely accommodated in the groove 231, that is, any end or any position of the laser module 25 does not protrude from the space where the groove 231 is located. Compared with the solution in which at least part of the laser module 25 protrudes from the inner surface of the accommodating chamber 21, the laser module 25 will not affect the insertion and removal of the aerosol generating product 1 and the assembly of other components in the accommodating chamber 21; at the same time, it can also prevent the aerosol generating product 1 and other components in the accommodating chamber 21 from damaging the laser module 25.

[0059] The length of the groove 231 refers to the size of the groove 231 along the central axis direction Y of the accommodating cavity 21; the width of the groove 231 refers to the size of the groove 231 along the circumferential direction of the accommodating cavity 21; and the depth of the groove 231 refers to the size of the groove 231 along the radial direction of the accommodating cavity 21. The length of the laser module 25 refers to the size of the laser module 25 along the central axis direction Y of the accommodating cavity 21; the width of the laser module 25 refers to the size of the laser module 25 along the circumferential direction of the accommodating cavity 21; and the thickness of the laser module 25 refers to the size of the laser module 25 along the radial direction of the accommodating cavity 21.

[0060] In a specific embodiment, see Figure 6 to Figure 7 . Figure 6 FIG. 4 is another schematic diagram of the overall structure of the heat sink. Figure 7 The schematic diagram of the structure of the laser module arranged in the heat dissipation part is shown in FIG. The heat dissipation element 23 includes a plurality of heat dissipation parts 234, and the plurality of heat dissipation parts 234 are distributed along the circumferential direction of the heat dissipation element 23, and each two adjacent heat dissipation parts 234 are detachably connected. Among the plurality of heat dissipation parts 234 constituting the heat dissipation element 23, at least one heat dissipation part 234 is used to assemble the laser module 25. The heat dissipation part 234 can assemble the laser module 25 by setting a groove 231. The groove 231 is set in the same manner as the above-mentioned groove 231. The separate structure of the heat dissipation element 23 allows the laser module 25 to be installed on a heat dissipation part 234 first, and then the other heat dissipation parts 234 are assembled with the heat dissipation part 234 on which the laser module 25 is installed, which is more conducive to the mounting of the laser module 25 than the integrated heat dissipation element 23. Specifically, after the laser module 25 is mounted, the two adjacent heat dissipation parts 234 are fixed by screws or solder mounting. Preferably, the number of the heat dissipation parts 234 can be two; in this way, the laser module 25 can be easily installed, and compared with the solution in which the heat dissipation element 23 includes more heat dissipation parts 234, the structure of the heat dissipation element 23 is simpler, easy to assemble, and saves assembly time.

[0061] Specifically, the groove 231 penetrates two end surfaces of the heat sink 23 along the central axis direction Y of the accommodating cavity 21 .

[0062] Specifically, the laser module 25 can be welded in the groove 231 by soldering; of course, the laser module 25 can also be fixed in the groove 231 by a fixing member. The fixing member can be a screw, a clamp, etc.

[0063] See also Figure 8 , Figure 8 It is a schematic diagram of the overall structure of the laser module. The laser module 25 includes a laser emitting area 251, or multiple laser emitting areas 251. The laser module 25 is used to convert electrical energy into laser light energy. The laser is irradiated on the aerosol generating matrix to locally generate high temperature of 200-500°C to generate aerosol by heating. The laser emitting area 251 extends along the central axis direction Y of the accommodating cavity 21, and multiple laser emitting areas 251 are arranged at intervals along the central axis direction Y of the accommodating cavity 21, and are used to emit lasers to heat the aerosol generating product 1 at corresponding positions. Specifically, the laser emitting area 251 provides an energy density of 0.5W / mm for the surface of the aerosol generating matrix of the aerosol generating product 1. 2 After the laser module 25 is powered on, the multiple laser emission areas 251 are sequentially lit to irradiate and heat different positions of the aerosol generating substrate, thereby achieving multiple puffs of the aerosol generating product 1.

[0064] In this embodiment, the laser module 25 also includes a plurality of positive and negative electrode pads 252, and every two positive and negative electrode pads 252 form a group of power supply electrodes. Each group of power supply electrodes corresponds to a laser emission area 251 and is electrically connected to the corresponding laser emission area 251 to supply power to the laser emission area 251, thereby respectively controlling whether each of the plurality of laser emission areas 251 is lit; after the laser module 25 is powered on, different positions of the aerosol generation matrix are sequentially lit and irradiated to realize multiple puffs.

[0065] Specifically, the laser module 25 may include two laser emitting regions 251 and three positive and negative electrode pads 252; the three positive and negative electrode pads 252 form two groups of power supply electrodes, that is, the two groups of power supply electrodes share one positive and negative electrode pad 252, and the two groups of power supply electrodes are electrically connected to the laser emitting regions 251 respectively to control whether the corresponding laser emitting regions 251 are lit. For ease of description, the following embodiments all take this as an example.

[0066] Specifically, the heat sink 23 may be made of aluminum alloy, copper, brass, etc., or a combination of multiple materials. Figure 5As shown, in order not to affect the instantaneous light efficiency of the laser module 25, the thickness T of the heat sink 23 on the second surface of the laser module 25 in the irradiation direction is greater than or equal to 2mm; for example, the thickness T is 2mm, 3mm, 5mm, or 8mm, etc. The unit heat dissipation volume is designed to be about 300-500mm based on the waste heat power. 3 / W; for example, 350mm 3 / W, 400mm 3 / W, 450mm 3 / W, 500mm 3 / W, etc. The total volume of the heat sink 23 is about 6000-10000mm 3 ; For example, 7000mm 3 、7500mm 3 , 8000mm 3 、8500mm 3 or 9000mm 3 In this way, the requirement that the temperature of the housing 20 of the aerosol generating device 2 is ≤ 48° C. can be met, thus avoiding the occurrence of burns.

[0067] It should be noted that the heat generated by the laser module 25 requires a certain volume of heat sink 23, such as a metal heat sink, to absorb the heat. The above unit heat dissipation volume means that under the current environment, 100-500mm is required for every 1W of waste heat. 3 The heat sink volume is used to absorb heat to ensure that the temperature of the aerosol generating device 2 does not exceed 48°C. Among them, according to the specific heat capacity of metal, the temperature of a unit area of ​​metal will rise after absorbing a certain amount of heat. We require the shell temperature to be no higher than 48°C. The heat sink usually needs to be kept within 50°C, so the temperature difference of the heat sink absorbing heat is fixed at 50-25°C; among them, 25°C refers to room temperature. It can be understood that if the heat is more, a larger volume of heat sink is needed to absorb the heat to ensure that the temperature of the heat sink will not be too high.

[0068] In some embodiments, the housing assembly further includes a rolling member 24, which is disposed between the outer surface of the side wall of the heat sink 23 and the inner surface of the housing 20, so as to reduce the friction resistance of the heat sink 23 relative to the housing 20 through the rolling member 24, so as to facilitate the smooth rotation of the heat sink 23. In a specific embodiment, at least one of the outer surface of the heat sink 23 and the inner surface of the housing 20 has a slide groove, and the rolling member 24 is embedded in the slide groove to limit the sliding direction and position of the rolling member 24. The rolling member 24 can be a ball.

[0069] Specifically, the inner surface of the housing 20 is provided with a first slide groove (not marked in the figure) and a second slide groove (not marked in the figure) extending along the circumferential direction of the housing 20. The first slide groove is provided at one end of the housing 20 away from the bottom of the accommodating cavity 21. The second slide groove is provided at one end of the housing 20 close to the bottom of the accommodating cavity 21. Figure 4 As shown, the outer surface of the heat sink 23 is provided with a third slide groove 232 and a fourth slide groove 233 extending along the circumferential direction of the heat sink 23. The third slide groove 232 is provided corresponding to the first slide groove and cooperates with the first slide groove to form a slideway; the fourth slide groove 233 is provided corresponding to the second slide groove and cooperates with the second slide groove to form another slideway, and the rolling element 24 is embedded in the slideway.

[0070] Specifically, the rolling element 24 may also be replaced by a bearing or other structure that facilitates rolling.

[0071] In another embodiment, see Figure 9-12 , Fig. 9 This is a cross-sectional view taken along the AA line of an aerosol generating system provided in another embodiment of the present application. Fig.10 for Fig. 9 A schematic diagram of the structure of the aerosol generating device; Fig.11 for Fig.10 The enlarged view of point B in the middle; Fig.12 It is an overall schematic diagram of an embodiment of an upper bracket. The shell assembly also includes an upper bracket 29, which can be made of Teflon or other metal materials. The upper bracket 29 is connected to the outer shell 20, and is located on the side of the cavity opening of the heat sink 23 facing the accommodating cavity 21; wherein, one of the upper bracket 29 and the heat sink 23 has a circumferential groove, and the other has a circumferential protrusion 291 matching the circumferential groove; the circumferential protrusion 291 is embedded in the circumferential groove and can slide along the extension direction of the circumferential groove. In this way, the circumferential protrusion 291 and the circumferential groove can be used to limit the heat sink 23 to prevent the heat sink 23 from shaking in the radial direction, and will not affect the rotation of the heat sink 23. In one embodiment, combined with Fig.12 The upper bracket 29 has a circumferential protrusion 291 on one side facing the heat sink 23, and the circumferential protrusion 291 is in a closed loop. The heat sink 23 has a circumferential groove on one side facing the cavity opening of the accommodating cavity 21, and the circumferential groove extends along the circumferential direction of the heat sink 23 and is in a closed loop. The circumferential protrusion 291 of the upper bracket 29 is embedded in the circumferential groove of the heat sink 23, and the heat sink 23 can rotate relative to the upper bracket 29.

[0072] Of course, in other embodiments, the outer surface of the side wall of the heat sink 23 can also be made of a material with a low friction coefficient, such as polytetrafluoroethylene (Teflon); the heat sink 23 with a low friction coefficient and the inner surface of the outer shell 20 slide and rotate through an arc-shaped constraint, thereby realizing low-resistance rotational movement of the heat sink 23 relative to the outer shell 20.

[0073] For details, see Figures 9 to 11. The housing assembly further includes a transmission gear 30 and a driving member (not shown); the transmission gear 30 is connected to the heat sink 23. In a specific embodiment, the transmission gear 30 is sleeved on the outer wall surface of the heat sink 23 and is interference fit with the heat sink 23 so as to be relatively fixed to the heat sink 23. Of course, in other embodiments, the transmission gear 30 may also be integrally formed with the heat sink 23; or the transmission gear 30 may be connected to the heat sink 23 by welding, clamp fixing, etc. The driving member is meshed with the transmission gear 30 to drive the transmission gear 30 to rotate, thereby driving the heat sink 23 to rotate. Furthermore, the outer wall surface of the side wall of the heat sink 23 at one end facing the upper bracket 29 is recessed toward the central axis M of the heat sink 23 to define a step, and the transmission gear 30 is sleeved on the step of the heat sink 23, and the outer wall surface of the side wall of the transmission gear 30 is flush with the outer wall surface of the side wall of the heat sink 23, and the side surface of the transmission gear 30 facing the upper bracket 29 is flush with the side surface of the heat sink 23 facing the upper bracket 29; in this way, the transmission gear 30 will not protrude from the outer wall surface of the heat sink 23, and the transmission gear 30 will not affect the connection between the upper bracket 29 and the heat sink 23 and the installation of other components in the outer casing 20, and it saves space and is conducive to the miniaturized production of the product.

[0074] In one embodiment, the housing assembly includes a light-transmitting tube 22, which is sleeved in a heat sink 23. The inner cavity of the light-transmitting tube 22 is used to accommodate and fix the aerosol-generating product 1 around the periphery. The laser module 25 is located between the light-transmitting tube 22 and the heat sink 23. The laser can penetrate the light-transmitting tube 22 and irradiate the aerosol-generating product 1. The aerosol-generating matrix of the aerosol-generating product 1 generates aerosol after being irradiated with laser light and heated. In this way, the light-transmitting tube 22 can be used to protect the laser module 25 to prevent the laser module 25 from being damaged during the process of inserting the aerosol-generating product 1 into the accommodating cavity. At the same time, by setting the light-transmitting tube 22 to be light-transmitting, such as a glass tube, compared with other non-light-transmitting tubes, such as a black tube, it will not affect the laser penetrating and irradiating the aerosol-generating product 1 in the light-transmitting tube 22.

The laser module 25 is located between the light-transmitting tube 22 and the heat sink 23. After the laser module 25 is powered on, the laser passes through the light-transmitting tube 22 and irradiates the aerosol-generating product 1 to heat it to form an aerosol.

[0076] In another embodiment, the light-transmitting tube 22 is configured to be rotatable relative to the aerosol-generating product 1, the light-transmitting tube 22 is fixedly mounted inside the heat sink 23, the heat sink 23 and the light-transmitting tube 22 rotate relative to the aerosol-generating product 1, and after the laser module 25 is powered on, the laser passes through the light-transmitting tube 22 and irradiates the aerosol-generating product 1 to heat and form an aerosol. The surface of the light-transmitting tube 22 is smooth, and is used to reduce the friction resistance of the heat sink 23 rotating relative to the aerosol-generating product 1.
