Description

Technical Field

[0001] The utility model relates to the technical field of aerosol heating, in particular to an aerosol generating device. Background Art

[0002] Electronic cigarettes are a type of heat-not-burn aerosol generating device that produces an aerosol for consumers to inhale by heating the aerosol generating product with a heating element but not burning it, thereby reducing the harmful smoke components produced by traditional aerosol generating products during the combustion process.

[0003] When consumers use it, the e-cigarette goes through a preheating stage and a suction stage. In the preheating stage, the heating element provides a large amount of heat to preheat the aerosol generating product, so that the aerosol generating product can quickly heat up and produce the first puff of smoke. Then the e-cigarette enters the suction stage, and the process of consumers inhaling the aerosol generating product mainly occurs in the suction stage.

[0004] However, in known electronic cigarettes, the heat distribution on the heating body is not uniform, and the temperature of the heat concentration area is significantly higher than that of other areas. During the preheating stage and the inhalation stage, the depth of the heating body inserted into the aerosol generating product remains unchanged, so that the part of the aerosol generating product corresponding to the heat concentration area on the heating body always corresponds to the heat concentration area on the heating body, which can easily cause the corresponding part of the aerosol generating product to overheat, while other parts of the aerosol generating product cannot be fully heated, resulting in low utilization rate of tobacco in the aerosol generating product.

[0060] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0061] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions, and the first feature "above", "above" and "above" the second feature include the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. The first feature "below", "below" and "below" the second feature include the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0064] like Figures 1 to 13As shown, this embodiment provides an aerosol generating device, in which the heating element 320 in the aerosol generating device is inserted into the accommodating cavity 210 at different depths during the preheating stage and the holding stage. Since the accommodating cavity 210 accommodates the aerosol generating product 1000, the heat concentration area of ​​the heating element 320 can be changed to the position of the aerosol generating product 1000 corresponding to the preheating stage and the holding stage. This can prevent the aerosol generating product 1000 from sticking to the heating element 320 due to over-baking, affecting the separation of the aerosol generating product 1000 from the heating element 320, and can fully heat the aerosol generating product 1000, which is beneficial to improving the utilization rate of the aerosol generating product 1000.

[0065] In some embodiments, the aerosol generating article 1000 includes a mouthpiece and an aerosol generating substrate. The aerosol generating substrate can generate a volatile substance when heated to a preset temperature. The volatile substance combines with air to form an aerosol. The aerosol generating substrate may contain tobacco or nicotine. The aerosol generating substrate has an upper end and a lower end that are arranged opposite to each other. The upper end is arranged toward the mouthpiece, and the lower end is arranged opposite to the mouthpiece. The user inhales the aerosol formed in the aerosol generating article 1000 by sucking on the mouthpiece.

[0066] In some embodiments, the aerosol-generating article 1000 comprises a cigarette.

[0067] The process of consumers inhaling the aerosol generating product 1000 mainly occurs in the suction stage. Before reaching the holding stage, it is necessary to go through a preheating stage so that the temperature of the aerosol generating matrix in the aerosol generating product 1000 can quickly reach a temperature capable of emitting smoke.

[0068] In some embodiments, the depth to which the heating element 320 is inserted into the receiving cavity 210 during the preheating stage includes a first depth, and the depth to which the heating element 320 is inserted into the receiving cavity 210 during the inhalation stage includes a second depth different from the first depth, for example, the first depth is greater than the second depth. By making the first depth different from the second depth, the heat concentration area of ​​the heating element 320 corresponds to a different position of the aerosol generating article 1000 during at least a portion of the preheating stage and during at least a portion of the holding stage. In other words, the position of the aerosol generating article 1000 mainly heated by the heating element 320 during at least a portion of the preheating stage is different from that during at least a portion of the holding stage. When the first depth is greater than the second depth, the depth to which the heating element 320 is inserted into the receiving cavity 210 during at least a portion of the preheating stage is greater than the depth to which the heating element 320 is inserted into the receiving cavity 210 during at least a portion of the holding stage. When the heating element 320 is inserted into the accommodating cavity 210 to a first depth during the preheating stage, the heat concentration area of ​​the heating element 320 is closer to the upper end of the aerosol generating substrate, which helps to quickly emit smoke during the inhalation process; at the same time, the contact area between the heating element 320 and the aerosol generating substrate can be increased, so that the aerosol generating substrate can absorb a large amount of heat in a short time, thereby shortening the preheating time; when the heating element 320 is inserted into the accommodating cavity 210 to a second depth during the holding stage, the heat concentration area of ​​the heating element 320 can be moved downward, and the contact area between the heating element 320 and the aerosol generating substrate can be reduced, which can reduce the heat intake of the aerosol generating substrate during the holding stage, and help prevent the aerosol generating product 1000 from being overheated and burnt.

[0069] In some embodiments, the heat provided by the heating element 320 to the aerosol generating article 1000 is adjusted mainly by changing the depth of the heating element 320 inserted into the accommodating cavity 210. Therefore, in this embodiment, the heating element 320 can have the same heating power in the preheating stage and the holding stage.

[0070] In some embodiments, when the depth of the heating element 320 inserted into the accommodating cavity 210 is a first depth, the heating power of the heating element 320 is the same as when the depth of the heating element 320 inserted into the accommodating cavity 210 is a second depth.

[0071] In some embodiments, the heat provided by the heating element 320 to the aerosol generating article 1000 is adjusted by changing the depth of the heating element 320 inserted into the accommodating cavity 210, and the heat provided by the heating element 320 to the aerosol generating article 1000 is adjusted by adjusting the electric power, current, voltage, pulse frequency, etc. provided by the power supply component 130 for the heating element 320 to generate heat.

[0072] For example, the heating power when the heating element 320 is inserted into the accommodating cavity 210 to a first depth is greater than the heating power when the heating element 320 is inserted into the accommodating cavity 210 to a second depth.

[0073] It should be noted that the heating power of the heating element 320 is affected by the current, voltage and / or pulse frequency provided by the power supply component 130. Therefore, by regulating the power output of the power supply component 130 to the heating element 320, the heating power and heating temperature of the heating element 320 can be adjusted. In some embodiments, the heating power of the heating element 320 is determined by at least one of the electric power, current and voltage provided by the power supply component 130 to the heating element 320. Regarding the control of the heating power of the heating element 320, it can be achieved by at least one of the current and voltage provided by the power supply component 130 to the heating element 320. For example, in the preheating stage and the holding stage, the current provided by the power supply component 130 to the heating element 320 is equal. For example, in the preheating stage and the holding stage, the voltage provided by the power supply component 130 to the heating element 320 is equal. For example, in the preheating stage and the holding stage, the energy provided by the power supply component 130 to the heating element 320 per unit time is equal. For another example, in the preheating stage and the maintaining stage, the power supply assembly 130 provides the same electric power to the heating element 320, that is, the heating efficiency of the heating element 320 is the same in the two stages.

[0074] Of course, in other embodiments, the heating power can also be changed while the first depth is greater than the second depth. Exemplarily, under the premise that the first depth is greater than the second depth, the heating power of the heating element 320 in the preheating stage is greater than the heating power in the holding stage. This arrangement enables the aerosol generating matrix to absorb heat faster, thereby further shortening the time of the preheating stage, reducing the waiting time of consumers before inhaling, and improving the user experience. Exemplarily, compared to the preheating stage, at least one of the current, voltage or electric power provided by the power supply component 130 to the heating element 320 in the holding stage can be appropriately reduced, so that the heating power of the heating element 320 in the heating component 300 is appropriately reduced.

[0075] The heat distribution on the heating element 320 is not uniform. In order to prevent the aerosol generating substrate from being burnt due to local overheating during the inhalation stage, and from being insufficiently baked due to local underheating, the insertion depth of the heating element 320 during the holding stage can also be changed.

[0076] In some embodiments, the holding stage includes a first stage and a second stage, and the depths of the heating element 320 inserted into the accommodating cavity 210 are different in the first stage and the second stage. Exemplarily, the depth of the heating element 320 inserted into the accommodating cavity 210 in the first stage is the third depth, and the depth of the heating element 320 inserted into the accommodating cavity 210 in the second stage is the fourth depth. In the order of time, the first stage is before the second stage, wherein the third depth is preferably greater than the fourth depth; wherein the third depth and the fourth depth may both be less than the second depth, or both be greater than the second depth, or the third depth is greater than the second depth, and the second depth is greater than the fourth depth; of course, the third depth or the fourth depth may also be equal to the second depth.

[0077] Alternatively, in some embodiments, the holding stage includes a first stage and a second stage. In a timing sequence, the first stage is before the second stage, the depth of the heating element 320 inserted into the accommodating cavity 210 in the first stage is the second depth, and the depth of the heating element 320 inserted into the accommodating cavity 210 in the second stage is the third depth, and preferably the second depth is greater than the third depth.

[0078] Alternatively, in some embodiments, the holding stage includes a first stage and a second stage. In a timing sequence, the first stage is before the second stage. The depth of the heating element 320 inserted into the accommodating cavity 210 in the first stage is a third depth. The depth of the heating element 320 inserted into the accommodating cavity 210 in the second stage is a second depth. Preferably, the third depth is greater than the second depth.

[0079] The holding stage is divided into a plurality of stages in sequence, for example, at least into a first stage and a second stage. By inserting the heating element 320 into the accommodating cavity 210 to different depths at different stages of the holding stage, the heat-concentrated area on the heating element 320 can heat different parts or areas of the aerosol generating product 1000, thereby preventing some areas or positions of the aerosol generating product 1000 from being over-baked while the remaining areas are not fully baked.

[0080] Preferably, the later the stage in the time sequence, the smaller the depth of the heating element 320 inserted into the accommodating cavity 210. Since the ignition point of the aerosol generating product 1000 decreases as the volatile substances in the aerosol generating product 1000 volatilize, reducing the depth of the heating element 320 inserted into the accommodating cavity 210 in the later stage can reduce the heat intake of the aerosol generating product 1000 and prevent the aerosol generating product 1000 from being burnt or burned.

[0081] The depth of the heating element 320 inserted into the accommodating cavity 210 is changed manually or automatically. In some embodiments, the aerosol generating device further comprises a driving mechanism 400 and a first holder 200, the accommodating cavity 210 is provided on the first holder 200, at least one of the heating assembly 300 and the first holder 200 including the heating element 320 is interfered with by the driving mechanism 400, so that the two move relative to each other under the driving of the driving mechanism 400, thereby changing the depth of the heating element 320 inserted into the accommodating cavity 210. Different objects are driven by the driving mechanism 400 to adapt to different internal structures of the aerosol generating device.

[0082] In some embodiments, the driving mechanism 400 and the heating assembly 300 are interfered with each other to drive the heating assembly 300 to move relative to the first holder 200. By driving the heating assembly 300 to move, the first holder 200 can be relatively fixed, which is conducive to simplifying the structure of the first holder 200 and improving the convenience of operation.

[0083] Combination Figure 3 As shown, in order to facilitate the driving of the heating element 320, in some embodiments, the heating assembly 300 includes a fixing member 310, the heating element 320 is linked to the fixing member 310, and the driving mechanism 400 is interfered with the fixing member 310. The heating assembly 300 is driven to move relative to the first retaining member 200. The above-mentioned setting of the driving position can make the heating element 320 not interfered and can give full play to its heating function.

[0084] In the first implementation of this embodiment, the fixing member 310 includes a base 3101, and the heating element 320 is fixed on the base 3101; the driving mechanism 400 is in interference fit with the base 3101. This arrangement enables the driving mechanism 400 to drive the base 3101 to move relative to the first holding member 200, thereby driving the heating element 320 to move relative to the first holding member 200.

[0085] In the second implementation of the present embodiment, the fixing member 310 further includes a second retaining member 3102, at least a portion of the first retaining member 200 is movably disposed in the second retaining member 3102, and the driving mechanism 400 is interference-matched with the second retaining member 3102. In the present implementation, the base 3101 is linked to the bottom of the second retaining member 3102. This arrangement enables the driving mechanism 400 to drive the second retaining member 3102 to move relative to the first retaining member 200, thereby driving the heating element 320 to move relative to the first retaining member 200 through the base 3101.

[0086] To facilitate driving the heating component 300 and / or the first retaining member 200, the driving mechanism 400 includes an electric driving unit 420 and a transmission unit. The electric driving unit 420 is electrically connected to the power supply component 130, and the transmission unit is interfered with at least one of the heating component 300 and the first retaining member 200, so that at least one of the heating component 300 and the first retaining member 200 is linked with the transmission unit, and the transmission unit can respond to the driving movement of the electric driving unit 420.

[0087] like Figure 5 , Fig. 9 and Fig.10 As shown, in the first implementation of this embodiment, the electric drive unit 420 includes an electromagnet 450, and the transmission unit includes a magnetic member 460 and a reset elastic member 470 for resetting the magnetic member 460. Among them, the reset elastic member 470 can apply elastic force to the magnetic member 460. Exemplarily, the electromagnet 450 is arranged on the housing 100 or a support frame 440 relatively fixed to the housing 100; the base 3101 is linked to the magnetic member 460, and the energized electromagnet 450 can adsorb the magnetic member 460 to the adsorption position, so as to increase the depth of the heating element 320 inserted into the accommodating cavity 210; the de-energized electromagnet 450 loses the adsorption force on the magnetic member 460, and under the action of the reset elastic member 470, the magnetic member 460 is driven to move to the reset position, thereby driving the depth of the heating element 320 inserted into the accommodating cavity 210 to decrease.

[0088] The electromagnet 450 has a mounting groove 451 inside, and the magnetic member 460 at the reset position is at least partially located in the mounting groove 451. The reset elastic member 470 is located in the mounting groove 451, and the two ends of the reset elastic member 470 abut against the magnetic member 460 and the electromagnet 450 respectively to apply elastic force to the magnetic member 460. The outer periphery of the base 3101 is connected or integrally formed with a connecting member 3104, and the connecting member 3104 is screwed to the magnetic member 460.

[0089] In the second implementation of this embodiment, the electric drive unit 420 includes a telescopic motor or a telescopic cylinder, and the transmission unit includes a connecting rod connected to the telescopic motor or the telescopic cylinder so as to be telescopic under the drive of the electric drive unit 420. Exemplarily, the base 3101 is linked to the connecting rod, and the connecting rod is driven to move under the action of the electric drive unit 420, so that the depth of the heating element 320 inserted into the accommodating cavity 210 can be changed.

[0090] In the third implementation of this embodiment, the electric drive unit 420 includes a rotary motor or a rotary cylinder, and the transmission unit includes a threaded rod connected to the rotary motor or the rotary cylinder so as to be able to rotate under the drive, and the threaded rod is threadedly connected to at least one of the heating component 300 and the first holder 200, so that at least one of the heating component 300 and the first holder 200 can move along the threaded rod. Exemplarily, the base 3101 is provided with a screw hole or the base 3101 is connected with a nut provided with a screw hole, and the threaded rod is threadedly engaged in the screw hole. During the rotation of the electric drive unit 420, the threaded rod is driven to rotate, thereby driving the base 3101 to move along the axial direction of the threaded rod, and then driving the depth of the heating element 320 inserted into the accommodating cavity 210 to change.

[0091] In the fourth implementation of the present embodiment, the electric drive unit 420 includes a rotating motor or a rotating cylinder, and the transmission unit includes a transmission rod connected to the rotating motor or the rotating cylinder so as to be able to rotate under the drive, and the transmission rod is connected to at least one of the heating component 300 and the first holder 200, so that at least one of the heating component 300 and the first holder 200 can rotate and move along the transmission rod. In other words, the transmission rod rotates around its own axis under the drive of the electric drive unit 420, thereby driving the base 3101 to rotate around its own axis, and at the same time, reciprocating along the axis of the transmission rod. Exemplarily, the cross section of the transmission rod is polygonal, the base 3101 is provided with a transmission hole whose profile is adapted to the cross section of the transmission rod, the transmission rod is penetrated in the transmission hole, the outer periphery of the base 3101 is provided with a thread, the base 3101 and the housing 100 are threadedly matched, and the transmission member can drive the base 3101 to rotate during the rotation process, so that the base 3101 can be lifted and lowered along the axis of the transmission rod during the rotation process around its own axis.

[0092] like Figures 6 to 8As shown, in order to facilitate the relative movement between the heating component 300 and / or the first holder 200, in some embodiments, the driving mechanism 400 can also be implemented by other structures. For example, the driving mechanism 400 includes an electric drive unit 420 and a rotating unit 410 that can be driven to rotate by the electric drive unit 420; a matching unit is provided on at least one of the heating component 300 and the first holder 200; one of the rotating unit 410 and the matching unit includes a slide rail 4111 that extends obliquely or spirally, and the other includes a sliding unit 311 that is slidably connected to the slide rail 4111. For example, the rotating unit 410 includes a spirally extending and groove-shaped slide rail 4111, and the matching unit includes a protruding sliding unit 311, which is inserted into the slide rail 4111 and can slide along the extension direction of the slide rail 4111. In some embodiments, the sliding portion 311 is disposed on the base 3101 of the heating component 300. Under the driving action of the electric drive portion 420, the rotating portion 410 rotates around its own axis, thereby driving the sliding portion 311 to move longitudinally, and then driving the base 3101 connected to the heating element 320 to move longitudinally.

[0093] To facilitate the linkage between the electric drive unit 420 and the rotating unit 410, in some embodiments, the driving mechanism 400 further includes a support frame 440 and a first gear 430, the first gear 430 is connected to the electric drive unit 420, the rotating unit 410 includes a second gear 412, the second gear 412 is meshed with the first gear 430 so as to be driven to rotate by the electric drive unit 420, and the rotating unit 410 is rotatably connected to the support frame 440. Through the gear transmission, the rotation angle of the rotating unit 410 can be accurately controlled, so that the longitudinal displacement of the heating element 320 can be accurately controlled.

[0094] In some embodiments, the rotating part 410 includes a sliding sleeve 411 , the second gear 412 is rotatably connected to the support frame 440 , the sliding sleeve 411 and the second gear 412 are coaxially linked, and the slide rail 4111 is disposed on the sliding sleeve 411 .

[0095] In some embodiments, the radius of the second gear 412 is greater than the radius of the first gear 430. This arrangement makes the rotation speed of the second gear 412 lower than the rotation speed of the first gear 430, which is more conducive to controlling the rotation angle of the second gear 412 and the longitudinal movement accuracy of the heating element 320.

[0096] In some embodiments, the longitudinal movement stroke of the heating element 320 is 2 mm to 3 mm. In some embodiments, the depth difference between the second depth and the first depth is 2 mm to 3 mm. In some embodiments, the depth difference between the second depth and the first depth is 5 mm to 20 mm. In other embodiments, the longitudinal movement stroke of the heating element 320 can also be reasonably set according to the length of the aerosol generating article 1000 and the specific length of the internal aerosol generating substrate, and is not limited to the above description.

[0097] In other embodiments, the heating assembly 300 and the first holder 200 can also rotate relative to each other, so that the depth of the heating element 320 inserted into the accommodating cavity 210 is different. In other words, the heating element 320 and the first holder 200 can move relative to each other and can also rotate relative to each other. With this arrangement, even if the heat concentration area of ​​the heating element 320 is distributed around the axis of the heating element 320 or along the axis of the heating element 320, the position of the heat concentration area can be changed relative to the aerosol generating product 1000, which can prevent the aerosol generating product 1000 from sticking to the heating element 320 due to over-baking, thereby affecting the separation of the aerosol generating product 1000 from the heating element 320; and can fully heat the aerosol generating product 1000, which is beneficial to improve the utilization rate of the aerosol generating product 1000.

[0098] like Figure 3 As shown, in this embodiment, the housing 100 has a first installation cavity 110 and a second installation cavity 120 capable of receiving at least part of the first retaining member 200, the base 3101 defines at least part of the boundary of the bottom of the second installation cavity 120, the second retaining member 3102 defines at least part of the boundary of the second installation cavity 120 in the circumferential direction, and the first retaining member 200 is configured to be at least partially located in the second retaining member 3102 when the heating assembly 300 is located in the first position. The above arrangement enables the base 3101 and the second retaining member 3102 to enclose part of the boundary of the second installation cavity 120 for accommodating at least part of the first retaining member 200.

[0099] In some embodiments, the second holder 3102 is slidably connected to the first holder 200. This arrangement can achieve stability of the first holder 200 during the process of entering and exiting the second mounting cavity 120, avoid misalignment, and help ensure accurate docking between the aerosol generating article 1000 in the first holder 200 and the heating element 320, thereby ensuring that the heat provided by the heating element 320 to the aerosol generating article 1000 is reasonably and effectively utilized.

[0100] The first retaining member 200 further comprises a tubular body 230 , the proximal end of which is open for at least a portion of the aerosol generating article 1000 to be inserted therein for retention, and a base 220 is disposed at the distal end of the tubular body 230 , and when the aerosol generating article 1000 is inserted into the tubular body 230 , it can abut against the base 220 .

[0101] There is a first gap between the tubular body 230 and the second retaining member 3102, and the first gap provides at least a part of the airway for the outside air to flow to the bottom support 220. With the above arrangement, before inhalation, the aerosol generating product 1000 needs to be placed in the tubular body 230, and then the tubular body 230 and the aerosol generating product 1000 are placed together in the second installation cavity 120, and the air can flow downward along the outer wall of the tubular body 230 and the first gap between the second retaining member 3102 to the bottom support 220, so that the aerosol generated by the aerosol generating product 1000 can flow out at the mouthpiece of the aerosol generating product 1000 and be inhaled by the user.

[0102] It should be noted that the above-mentioned proximal end and distal end are both based on the state of the aerosol generating device when the user uses the aerosol generating device. The proximal end is the end position close to the user's mouth, and the distal end is the end position away from the user's mouth.

[0103] Combination Figure 4 and Fig.13 As shown, in some embodiments, the inner wall of the tubular body 230 has a third protrusion 231, and the third protrusion 231 is used to abut the aerosol generating article 1000 so that a second gap is formed between the inner wall of the tubular body 230 and the aerosol generating article 1000, and the second gap provides at least a part of the airway for the outside air to flow to the bottom support 220. In one implementation of this embodiment, a plurality of third protrusions 231 are provided, and the plurality of third protrusions 231 are arranged on the inner wall of the tubular body 230 around the axis of the tubular body 230, and any two third protrusions 231 are formed with a notch. The outside air can enter the second gap through the notch and finally flow to the bottom support 220. Further, the plurality of third protrusions 231 are evenly distributed on the inner wall of the tubular body 230. With this arrangement, the air can flow evenly to the bottom support 220. In another implementation of this embodiment, a connecting groove is provided on the inner wall of the tubular body 230, and the connecting groove connects the outside and the bottom support 220. This arrangement allows external air to flow to the base 220 through the connecting groove.

[0104] In some embodiments, the heating element 320 extends longitudinally, and the driving mechanism 400 can drive the fixing member 310 to move longitudinally. For ease of description and understanding, in order to achieve different depths of the heating element 320 inserted into the accommodating cavity 210, it can be achieved by moving the fixing member 310, wherein the fixing member 310 can move between a first position and a second position.

[0105] Combination Figure 3 and Fig.13 As shown, the bottom bracket 220 is arranged at the bottom of the first retaining member 200, and an avoidance hole 221 is arranged at the middle position of the bottom bracket 220. When the fixing member 310 is located at the first position, at least a part of the heating element 320 passes through the avoidance hole 221. The above arrangement enables the bottom bracket 220 to move upward while holding the lower end of the aerosol generating product 1000 when the first retaining member 200 moves upward, thereby loosening the connection between the aerosol generating product 1000 and the heating element 320, making it easier to pull out the aerosol generating product 1000 later, and preventing the aerosol generating product 1000 from breaking during the pulling out process.

[0106] Combination Figure 3 and Figure 4 As shown, in some embodiments, at least part of the driving mechanism 400 is disposed in the first mounting cavity 110. To prevent the aerosol in the second mounting cavity 120 from diffusing into the first mounting cavity 110, the sealing member 500 provides a sealed connection between the housing 100 and the fixing member 310, so that the second mounting cavity 120 is sealed and isolated from the first mounting cavity 110. The above arrangement prevents the aerosol generated by the aerosol generating article 1000 in the second mounting cavity 120 from entering the first mounting cavity 110, which is conducive to ensuring the function of the driving mechanism 400, thereby ensuring that it can smoothly drive the fixing member 310 to move relative to the first retaining member 200, thereby improving the user experience.

[0107] Since the fixing member 310 and the first retaining member 200 have relative motion, at least part of the sealing member 500 will change or deform. In other words, during the longitudinal movement of the fixing member 310, part of the sealing member 500 remains stationary, and part of the sealing member 500 deforms and / or moves. The above-mentioned structure can make the sealing member 500 meet the sealing requirements between two relatively moving parts.

[0108] Combination Figure 4As shown, in some embodiments, the sealing member 500 includes a connecting portion 530, a first sealing portion 510 sealedly connected to the housing 100, and a second sealing portion 520 sealedly connected to the fixing member 310; the connecting portion 530 is sealedly connected between the first sealing portion 510 and the second sealing portion 520; the connecting portion 530, the first sealing portion 510 and the second sealing portion 520 are separately arranged. This arrangement facilitates the separate production of each component in the sealing member 500, and also facilitates the assembly between the first sealing portion 510 and the housing 100, and facilitates the assembly between the second sealing portion 520 and the fixing member 310. In other implementations of this embodiment, the connecting portion 530 is integrally formed with at least one of the first sealing portion 510 and the second sealing portion 520. Exemplarily, the connecting portion 530 is integrally formed with the first sealing portion 510 and the second sealing portion 520. This molding method is conducive to ensuring the sealing performance between the components. In this embodiment, during the movement of the fixing member 310 , the first sealing portion 510 remains stationary, the connecting portion 530 is deformed, and the second sealing portion 520 moves in the longitudinal direction.

[0109] Combination Figure 3 and Figure 4 As shown, in order to facilitate fixing the first sealing portion 510 of the sealing member 500, in some embodiments, the aerosol generating device further comprises a bracket 600 fixed relative to the housing 100, and at least a part of the bracket 600 is fixed in the housing 100; the bracket 600 supports the sealing member 500, and the first sealing portion 510 is arranged between the housing 100 and the bracket 600, and the second sealing portion 520 is arranged between the fixing member 310 and at least the fixing member 310 in the bracket 600. With the arrangement of the bracket 600, the sealing member 500 is subjected to an upward supporting force, so that the sealing member 500 is conveniently installed on the bracket 600 first and then the two are placed together in the housing 100. In the process of moving the bracket 600 from bottom to top during the installation process, the sealing member 500 is simultaneously pushed upward, and finally the sealing member 500 is sandwiched between the bracket 600 and the housing 100. The second sealing portion 520 is sealingly connected to the fixing member 310 , and when the fixing member 310 is located at the second position, the second sealing portion 520 is also connected to the bracket 600 , that is, in the suction stage, at least part of the second sealing portion 520 is sandwiched between the fixing member 310 and the bracket 600 .

[0110] The bracket 600 includes a support body 610 and a support platform 620 disposed on the support body 610. When the fixing member 310 is located at the second position, the lower end of the second sealing portion 520 abuts against the support platform 620. The support body 610 may be cylindrical, and at least a portion of the fixing member 310 is slidably disposed in the support body 610. Further, a second protrusion 630 is disposed on the support platform 620, and the second protrusion 630 is used to support the sealing member 500; and the first sealing portion 510 is sandwiched between the second protrusion 630 and the housing 100.

[0111] Recombination Fig.11 As shown, in order to improve the convenience of installation, an annular first protrusion 511 is provided on the outer periphery of the first sealing portion 510. The first protrusion 511 is more likely to be deformed after being squeezed than the first sealing portion 510 with a larger area, so that it is easier to sandwich the first sealing portion 510 between the housing 100 and the second protrusion 630; at the same time, the first protrusion 511 that is more likely to be deformed is also easier to achieve a sealing effect, preventing gas from passing between the first protrusion 511 and the housing 100.

[0112] Recombination Fig.12 As shown, during the movement of the fixing member 310 between the first position and the second position, the second sealing portion 520 is driven to move. In order to strengthen the connection between the second sealing portion 520 and the fixing member 310, in some embodiments, the second sealing portion 520 includes a second vertical sealing portion 521 and a second horizontal sealing portion 522 arranged on the second vertical sealing portion 521, and a sealing docking portion 3103 is arranged on the periphery of the fixing member 310, and the sealing docking portion 3103 and the second horizontal sealing portion 522 are arranged to overlap in sequence along the longitudinal direction. Among them, the directions of the second vertical sealing portion 521 and the second horizontal sealing portion 522 are perpendicular, that is, the second vertical sealing portion 521 extends in the longitudinal direction, and the second horizontal sealing portion 522 extends in the transverse direction. The above-mentioned structure is arranged so that during the process of the fixing member 310 moving in the longitudinal direction, the fixing member 310 and the second sealing part 520 interact with each other through the sealing docking part 3103 and the second horizontal sealing part 522, and the sealing docking part 3103 generates a vertical force on the second horizontal sealing part 522 to complete the longitudinal driving of the second sealing part 520.

[0113] In some embodiments, the support body 610 of the bracket 600 is slidably connected to the fixing member 310. The bracket 600 and the housing 100 are relatively fixed, and the fixing member 310 and the support body 610 are slidably connected so that the fixing member 310 moves smoothly between the first position and the second position relative to the housing 100. In some embodiments, the support frame 440 is fixed relative to the housing 100, or the support frame 440 and the bracket 600 are integrally formed.

[0114] In some embodiments, the connecting portion 530 is configured to deform and / or move during the longitudinal movement of the fixing member 310. Exemplarily, in an embodiment where the connecting portion 530, the first sealing portion 510, and the second sealing portion 520 are integrally formed, the connecting portion 530 is twisted and deformed during the longitudinal movement of the fixing member 310. In another exemplary embodiment, in an embodiment where the connecting portion 530 and the second sealing portion 520 are integrally arranged and the connecting portion 530 and the first sealing portion 510 are separately arranged, the connecting portion 530 changes position during the longitudinal movement of the fixing member 310. The connecting portion 530 and the first sealing portion 510 are sealed and slidably matched.

[0115] Combination Figure 3 and Figure 4 In some embodiments, the longitudinal orthographic projection of the first sealing portion 510 is located outside the longitudinal orthographic projection of the second sealing portion 520. The above structure allows the first sealing portion 510 and the second sealing portion 520 to be longitudinally staggered, which facilitates the relative movement of the two in the longitudinal direction without position interference; at the same time, the longitudinally staggered first sealing portion 510 and the second sealing portion 520 also provide space for the arrangement of the connecting portion 530.

[0116] In order to facilitate the relative movement between the first sealing portion 510 and the second sealing portion 520, in some embodiments, when the fixing member 310 is in the first position, the connecting portion 530 is tilted. This arrangement provides sufficient length margin for the deformation of the connecting portion 530, so as to facilitate the movement of the fixing member 310 between the first position and the second position. In some embodiments, when the fixing member 310 is in the second position, the connecting portion 530 is tilted.

[0117] In some embodiments, when the fixing member 310 is located at the first position and the second position, the connecting portion 530 is tilted and has a first inclination and a second inclination, respectively, and the first inclination is smaller than the second inclination. This arrangement makes the length of the connecting portion 530 greater than the distance between the first sealing portion 510 and the second sealing portion 520 in the lateral direction, so that the deformation of the connecting portion 530 provides a sufficient length margin.

[0118] In some embodiments, when the fixing member 310 is located at the first position, the connecting portion 530 is tilted, and when the fixing member 310 is located at the second position, the connecting portion 530 is horizontally arranged.

[0119] In some embodiments, when the fixing member 310 is in the first position, the connecting portion 530 is tilted downwardly toward the second sealing portion 520 , and when the fixing member 310 is in the second position, the connecting portion 530 is tilted upwardly toward the second sealing portion 520 .

[0120] To improve the durability of the seal 500, in some embodiments, at least the connecting portion 530 in the seal 500 is an elastic member. When the fixing member 310 is in the first position, the connecting portion 530 is in an elastic stretching state. In one implementation of this embodiment, when the fixing member 310 is in the first position, the connecting portion 530 is in an elastic stretching state, and when the fixing member 310 is in the second position, the connecting portion 530 is in an initial state. In another implementation of this embodiment, when the fixing member 310 is in the first position, the connecting portion 530 is in an elastic stretching state and has a first elongation, and when the fixing member 310 is in the second position, the connecting portion 530 is also in an elastic stretching state and has a second elongation, and the first elongation is greater than the second elongation.

[0121] Recombination Figure 1 As shown, the aerosol generating device further includes a housing 700, which is sleeved on the outer side of the housing 100 to form a protective shell of the aerosol generating device. Among them, patterns or texts can be set on the housing 700 to serve as an indicator mark of the suction end and charging port of the aerosol generating device, and can also be used to improve the overall aesthetics.

[0122] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
