[0162] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0163] One embodiment of this application discloses an aerosol generation system for atomizing a liquid matrix to generate an inhalable aerosol. The aerosol generation system of this disclosure can also be characterized as an aerosol delivery or drug delivery article. Therefore, such a device or system can be adapted to provide one or more inhalable forms or states of a substance (e.g., flavoring agents and / or pharmaceutical active ingredients). For example, the inhalable substance can be substantially in aerosol form (i.e., a suspension of fine solid particles or droplets in a gas). Accordingly, the atomized liquid matrix can be a liquid precursor comprising flavoring agents and / or pharmaceutical active ingredients before aerosol formation. In a more preferred embodiment, the liquid matrix is ​​a pharmaceutical agent for generating an inhalable drug; then the aerosol generation system is a drug delivery device suitable for medical use.

[0164] Figure 1 and Figure 2 A schematic diagram of an aerosol generation system in one embodiment is shown; the system typically includes several components disposed within an external body or housing (which may be referred to as a shell). The overall design of the external body or housing can vary, and the type or configuration of the external body that defines the overall size and shape of the aerosol generation system can vary. Typically, a body resembling an elongated rod or bar shape can be formed from a single integral shell, or the shell can be formed from two or more separable bodies. For example, the aerosol generation system may have a control body at one end, which has a housing containing one or more reusable components (e.g., a battery such as a rechargeable battery and / or a rechargeable supercapacitor, and various electronic devices for controlling the operation of the article), and an external body or housing at the other end that can be removably coupled and contains disposable parts (e.g., a disposable liquid source, fragrance cartridge).

[0165] Further in Figure 1 and Figure 2 In the specific implementation shown, the aerosol generation system includes:

[0166] The device includes an aerosol generating apparatus 100 and a liquid source 200 that can be used disposablely or reusably. In some alternative embodiments, the liquid source 200 can be prepared in the form of capsules, liquid capsules, etc., containing a liquid matrix that can be atomized by the aerosol generating apparatus 100 to generate aerosols. During use, the liquid source 200 can be received into or removed from the aerosol generating apparatus 100 by the user. Typically, in some embodiments, when the user needs to perform aspiration, the liquid source 200 is received into the aerosol generating apparatus 100, allowing the aerosol generating apparatus 100 to obtain the liquid matrix within the liquid source 200 and atomize it to generate aerosols. When the liquid matrix within the liquid source 200 is depleted, the user can remove the liquid source 200 from the aerosol generating apparatus 100 for replacement, etc.

[0167] See further Figures 2 to 4 In one specific embodiment shown, the liquid source 200 is generally configured in a columnar shape, including:

[0168] The outer wall 220 is basically arranged in a ring; in Figure 4 In one embodiment shown, the outer wall 220 is generally elliptical cylindrical in shape;

[0169] The top wall 210 is located at the first end of the outer wall 220 along the axial direction, and seals the outer wall 220 at the first end of the outer wall 220.

[0170] The fractured wall 240 is located at the second end of the outer wall 220 along the axial direction.

[0171] In some embodiments, a reservoir 250 for storing a liquid matrix is ​​formed by at least a portion of the interior of the outer wall 220 being hollow. Alternatively, in another embodiment, the reservoir 250 for storing a liquid matrix is ​​defined by the outer wall 220, the fractured wall 240, and the top wall 210 together.

[0172] In practice, at least part of the fractured wall 240 can be broken or fractured under compression or puncture, forming a rupture or break, thereby causing the liquid matrix in the reservoir 250 to flow out and be atomized.

[0173] In some embodiments, the top wall 210 and the outer wall 220 are coupled and connected by molding from a moldable material. The top wall 210 and the outer wall 220 are both substantially rigid.

[0174] In some embodiments, the fractured wall 240 may be a flexible sealing membrane or a rigid film, etc. The fractured wall 240 may include a metal foil, a polymer film, etc.

[0175] Furthermore, in implementation, the top wall 210 is a part for the user to operate the liquid source 200 by gripping and applying force with their fingers during the above operations; at the same time, in order to facilitate the user's operation, the operating part 210 has a larger cross-sectional area than the outer wall 220, which is beneficial to the user's operation convenience.

[0176] Further based on Figures 2 to 4 As shown, the liquid source 200 also includes:

[0177] Flexible element 230; in one embodiment shown in the figure, the flexible element 230 is configured to be annular around or attached to the outer sidewall 220; and the flexible element 230 protrudes from the surface of the outer sidewall 220.

[0178] In one implementation, the flexible element 230 is used to at least partially squeeze or compress the liquid source 200 when it is received in the aerosol generating device 100, thereby forming an interference fit between the liquid source 200 and the aerosol generating device 100, so that the liquid source 200 can be received stably in the aerosol generating device 100 without loosening or detachment.

[0179] In some other implementations, the flexible element 230 is also used to seal the joint gaps between the aerosol generating devices 100 when the liquid source 200 is received in the aerosol generating device 100, so as to prevent leakage from the gaps between them.

[0180] Further based on Figures 2 to 4 As shown, the liquid source 200 can be received by the aerosol generating device 100 from one or more angles. Specifically, the liquid source 200, which is substantially elliptical cylindrical in shape, is centrally symmetrical; therefore, in practice, the liquid source 200 can be... Figure 2 The angle shown, or after rotating 180 degrees around the axis, can be received by the aerosol generating device 100.

[0181] See further Figures 1 to 3 As shown, the main body of the aerosol generating device 100 is constructed to be cylindrical; specifically in the embodiment shown in the figure, the main body of the aerosol generating device 100 has a length direction, a width direction and a thickness direction; and the length dimension of the main body of the aerosol generating device 100 is greater than the width dimension and the width dimension is greater than the thickness dimension.

[0182] Further, as shown in the figure, the aerosol generating device 100 includes:

[0183] The proximal end 110 and distal end 120 are opposite each other along the length direction; and the left end 130 and right end 140 are opposite each other along the width direction. In use, the proximal end 110 is usually the end closer to the user.

[0184] In some embodiments, the aerosol generating device 100 may include a separate, individual housing that can be formed from any of a variety of different materials. The housing may be formed from any suitable structurally sound material. In some examples, the housing may be formed from a metal or alloy such as stainless steel or aluminum. Other suitable materials include various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, and so on.

[0185] Furthermore, in some embodiments, the housing structure of the aerosol generating device 100 includes:

[0186] The upper housing 11 is located near the proximal end 110, and the lower housing 12 is located near the distal end 120. In practice, the upper housing 11 and the lower housing 12 together define the outer shell of the aerosol generating device 100.

[0187] In the embodiment shown in the figure, the upper housing 11 defines the proximal end 110 of the aerosol generating device 100, and the lower housing 12 defines the distal end 120 of the aerosol generating device 100.

[0188] In some embodiments, after assembly, the upper housing 11 and the lower housing 12 are substantially non-removable or non-separable by the user.

[0189] Furthermore, in some embodiments, the upper housing 11 is rigid, while at least a portion of the surface of the lower housing 12 is flexible.

[0190] Further based on Figure 3 In the preferred embodiment shown, the lower housing 12 includes a rigid inner layer 121 and a flexible covering layer 122 that covers or forms outside the rigid inner layer 121; thus, in this embodiment, the rigid inner layer 121 provides rigid support and connection, and the flexible covering layer 122 provides surface flexibility. In some embodiments, the rigid inner layer 121 may include metal, organic polymer, etc.; the flexible covering layer 122 may include silicone, elastomer, flexible resin, etc.

[0191] In some embodiments, the rigid inner layer 121 and the flexible covering layer 122 of the lower housing 12 are formed by injection molding two moldable materials into a mold using a two-color injection molding process, followed by curing. The rigid inner layer 121 and the flexible covering layer 122 obtained by two-color injection molding are substantially inseparable.

[0192] Specifically Figure 3 In a more preferred embodiment shown, the aerosol generating apparatus 100 includes:

[0193] The button switch 30 allows the user to activate or turn on the aerosol generator 100 by pressing the button switch 30, so that the aerosol generator 100 atomizes the liquid matrix originating from the liquid source 200 to generate inhalable aerosols.

[0194] In some embodiments, the push-button switch 30 is disposed on the lower housing 12; and the push-button switch 30 is disposed on the left side end 130.

[0195] See further Figure 1 and Figure 2 As shown, the aerosol generating device 100 includes:

[0196] The nozzle 20 is removably coupled to the aerosol generating device 100 for use by a user to aspirate the generated aerosol. Of course, based on conventional design, the nozzle 20 has an air intake A at its free end, through which the user aspirates the aerosol during suction.

[0197] In some embodiments, the nozzle 20 is removably attached to the upper housing 11; and the nozzle 20 is disposed at the left end 130.

[0198] In some embodiments, the nozzle 20 is at least partially flexible; for example, the nozzle 20 is made of flexible silicone material.

[0199] In some embodiments, the nozzle 20 is a hollow cylindrical shape.

[0200] In some embodiments, at least a portion of the nozzle 20 near the air intake A is flattened. Specifically in Figure 1 In this design, at least a portion of the nozzle 20 near the intake port A has a width dimension w1 greater than its thickness dimension h1, thus exhibiting a flat shape. Simultaneously, the intake port A is also a flat shape with a width dimension greater than its thickness dimension. Furthermore, the cross-sectional area of ​​at least a portion of the nozzle 20 gradually decreases along the direction approaching the intake port A.

[0201] according to Figure 3 In one embodiment shown, the aerosol generating device 100 is provided with a substantially circular insertion groove 112; correspondingly, the nozzle 20 is opposite to the connecting portion 22 of the suction port A, and during assembly, the connecting portion 22 is at least partially inserted into or extends into the insertion groove 112 to connect with the aerosol generating device 100. Accordingly, the cross-sectional area of ​​the connecting portion 22 is smaller than the maximum cross-section of the nozzle 20. In some embodiments, the cross-section of the insertion groove 112 is substantially circular; and the insertion groove 112 has a depth of approximately 4 to 10 mm.

[0202] Further in Figure 1In a more preferred embodiment, the free end of the nozzle 20, at a distance d1 along the width direction of the aerosol generating device 100 relative to the left end 130, has a feature that allows the user's fingers to smoothly press or operate the button switch 30 simultaneously while the user's lips are drawing air from the inhalation port A. Alternatively, the nozzle 20, at a distance d2 along the length direction of the aerosol generating device 100 relative to the button switch 30, has a feature that allows the user's fingers to smoothly press or operate the button switch 30 simultaneously while the user's lips are drawing air from the inhalation port A.

[0203] In some embodiments, the distance d1 between the free end of the nozzle 20 and the left end 130 along the width direction of the aerosol generating device 100 is greater than 15 mm; more preferably, the distance d1 is greater than 20 mm; in the specific embodiment shown in the figure, the distance d1 is 34 mm. Alternatively, in some embodiments, the distance d2 between the nozzle 20 and the push-button switch 30 along the length direction of the aerosol generating device 100 is greater than 8 mm; more preferably, the distance d2 is greater than 12 mm; in the specific embodiment shown in the figure, the distance d2 is 17 mm.

[0204] Further based on Figure 3 As shown, the axial or extending direction of the suction nozzle 20 is at an angle to the length direction of the aerosol generating device 100; thus, the suction nozzle 20 is arranged at an angle and is relatively inclined toward the proximal end 110, which is also away from the push-button switch 30, which is advantageous for the user to operate the push-button switch 30 smoothly during suction.

[0205] See further Figure 2 As shown, the aerosol generating device 100 includes:

[0206] The receiving cavity 510 is located near the proximal end 110 and is either open or exposed at the proximal end 110; thus, in use, the liquid source 200 can be removably received at the proximal end 110 into the receiving cavity 510.

[0207] Further based on Figure 3 In the preferred embodiment shown, the aerosol generating apparatus 100 further includes:

[0208] A rechargeable battery cell 150 is used for power supply; the battery cell 150 is basically housed within the lower housing 12.

[0209] A charging port 124 is located at the distal end 120; during use, the battery cell 150 is charged through this charging port 124; and,

[0210] Circuit board 160 controls the operation of aerosol generating device 100.

[0211] See further Figures 5 to 10 As shown, the aerosol generating device 100 also includes:

[0212] The atomizing mechanism 40 is used to atomize the liquid matrix provided by the liquid source 200 to generate an aerosol.

[0213] In the specific embodiment shown in this figure, the atomizing mechanism 40 includes at least a vibrating element 42, which atomizes the liquid matrix transmitted to the vibrating element 42 into an aerosol through mechanical vibration. In an optional embodiment, the vibrating element 42 can be a conventional sheet-like ultrasonic vibrating component or a sheet-like piezoelectric ceramic; or, for example, the ultrasonic atomizing sheet proposed in patent CN112335933A. During use, these vibrating elements 42 disperse the liquid matrix through high-frequency vibration (preferably a vibration frequency of 1.7MHz to 4.0MHz, which is beyond the range of human hearing and belongs to the ultrasonic band) to generate a naturally suspended aerosol of particles, which is then output to the suction nozzle 20.

[0214] In typical implementation, the atomizing mechanism 40, especially the vibrating element 42, is activated or started by the user through the operation of the button switch 30.

[0215] Further based on Figures 5 to 10 In a preferred embodiment, the aerosol generating apparatus 100 further includes:

[0216] Container 50, located near proximal end 110; essentially, after assembly, container 50 is situated within upper housing 11. In implementation, the space within container 50 at least partially defines a receiving cavity 510 for receiving and containing liquid source 200. In some embodiments, container 50 also forms a liquid delivery channel 520 for delivering a liquid matrix originating from liquid source 200 to atomizing mechanism 40, particularly vibrating element 42.

[0217] In terms of arrangement, both the container 50 and the atomizing mechanism 40 are housed and held within the upper housing 11; the container 50 is relatively closer to the right end 140, and the atomizing mechanism 40 is relatively closer to the left end 130.

[0218] Further based on Figures 5 to 10 As shown, the receiving cavity 510 defined within the container 50 is closer to the proximal end 110 than the liquid transfer channel 520. The container 50 also includes:

[0219] The puncture mechanism 60, which is at least partially exposed within the receiving cavity 510, is used to puncture the fractured wall 240 of the liquid source 200 when the liquid source 200 is received into the receiving cavity 510, thereby releasing the liquid matrix within the liquid source 200 into the liquid delivery channel 520 after puncture.

[0220] exist Figure 9In one embodiment shown, the piercing mechanism 60 includes:

[0221] A puncturing element is used to puncture the fractured wall 240 of the liquid source 200. In this embodiment, the puncturing element is movably disposed within the container 50, particularly rotatably.

[0222] The puncturing element includes at least an elongated first spiral arm 610 and a second spiral arm 620; an angle exists between the first spiral arm 610 and the second spiral arm 620. As shown in the figure, the angle between the first spiral arm 610 and the second spiral arm 620 is an obtuse angle greater than 90 degrees.

[0223] A connector 63 is used to stably install and connect the puncturing mechanism 60 within the container 50. Specifically, the container 50 has a insertion hole 55, and the connector 63 has a pin portion 632, which is inserted into the insertion hole 55 during assembly to stably connect with the container 50. The connector 63 also has a base portion 631, which is mainly used for assembling the puncturing component; in the figure, the base portion 631 also has an assembly groove 633 for mounting the puncturing component.

[0224] The pin 64 passes through the first mounting hole 634 on the base portion 631 and the second mounting hole 613 on the puncture member in sequence; after assembly, the puncture member is stably connected and held on the base portion 631 of the connector 63 by the pin 64; and after assembly, the puncture member can rotate about the pin 64.

[0225] In the above implementation, the piercing mechanism 60 is non-removable after assembly; therefore, the piercing mechanism 60 cannot be removed from the receiving cavity 510 or extended outside the opening, which improves the safety of the device by preventing the piercing mechanism 60 from piercing the user's fingers during use.

[0226] Meanwhile, the puncture mechanism 60 is basically away from the opening of the receiving cavity 510 and is attached to the inner bottom wall of the receiving cavity 510 away from the opening; this is advantageous in preventing the user from coming into contact with the puncture mechanism 60 when changing the liquid source 200, avoiding scratching or puncturing the user's fingers during operation, and improving the safety of the device.

[0227] Alternatively, in other variations, the first rotating arm 610 may be configured to move linearly and telescopically, capable of piercing the fractured wall 240 of the liquid source 200 through linear movement.

[0228] In some embodiments, the second mounting hole 613 is located at the connection between the first rotating arm 610 and the second rotating arm 620.

[0229] In some embodiments, the first spiral arm 610 is generally in the shape of a thin sheet; the free tip 611 of the first spiral arm 610 is configured to be thin or sharp or wedge-shaped, which is advantageous for piercing in use.

[0230] In some embodiments, the first rotating arm 610 is further provided with a first protrusion 612. Specifically, the first protrusion 612 is located on both sides of the first rotating arm 610 in the thickness direction. Furthermore, the height of the first protrusion 612 gradually decreases at least partially along the direction near the free front end 611; thus, at least a portion of the first protrusion 612 near the free front end 611 is inclined. Therefore, when the free front end 611 pierces the fractured wall 240 of the liquid source 200, it is advantageous to enlarge the rupture opening of the fractured wall 240 through the first protrusion 612.

[0231] In some embodiments, the second rotating arm 620 has a free end opposite to the first rotating arm 610; the second rotating arm 620 has a volume-enlarged portion 621 at the free end. At least a portion of the surface of the volume-enlarged portion 621 is arranged at an angle.

[0232] In some embodiments, the puncturing element comprises at least part of metal; or, the first rotating arm 610 comprises metal; making the first rotating arm 610 comprise a free front end 611 of metal material can have suitable hardness and ease of processing, which is advantageous for puncturing.

[0233] See further Figures 5 to 7 As shown, the container 50 is also provided with a biasing element for biasing or resetting the first rotating arm 610 toward a first position by a biasing force. Specifically, the figure includes a magnetic body 53; correspondingly, the free end 611 of the first rotating arm 610 includes a magnetic metal or alloy; thus, the first rotating arm 610 can be magnetically attracted and stably bonded to the inner surface of the container 50 by the magnetic body 53. In optional embodiments, the magnetic metal or alloy includes iron, cobalt, nickel, or an alloy containing at least one of them, such as stainless steel, iron-aluminum alloy, permalloy, etc.

[0234] Alternatively, in another variation of the embodiment, the magnetic body 53 may be replaced by an elastic element such as a torsion spring or spring, which uses elastic force to reset the first rotating arm 610 in a direction away from the proximal end 110, so that the free front end 611 of the first rotating arm 610 is basically biased or biased away from the proximal end 110.

[0235] See further Figures 5 to 7 As shown, a stop protrusion 54 is also provided inside the container 50; when the liquid source 200 is received into the receiving cavity 510, the liquid source 200 abuts against the stop protrusion 54 to provide a stop. Of course, this is mainly due to the rigid outer wall 220 of the liquid source 200 abutting against the stop protrusion 54.

[0236] Further details regarding the puncture process of the puncture mechanism 60 against the liquid source 200 during implementation can be found in [link to documentation]. Figures 5 to 7 shown. specific:

[0237] Figure 5 The diagram shows a first position of the puncture mechanism 60 before the liquid source 200 is received into the receiving cavity 510 of the container 50. In this first position, the first spiral arm 610 of the puncture member is magnetically attracted by the magnetic body 53 and thus stably attached to or bonded to the inner surface of the container 50; the first spiral arm 610 is substantially horizontal. Also in this first position, the second spiral arm 620 is relatively closer to the proximal end 110 and is tilted relative to the first spiral arm 610.

[0238] Figure 6 The diagram illustrates a state in which the liquid source 200 is partially received by the receiving cavity 510 and contacts the second rotating arm 620. When the liquid source 200 is placed into the receiving cavity 510 along the direction indicated by arrow R3 in the diagram, the rigid outer wall 210 of the liquid source 200 first contacts the free end of the second rotating arm 620 and forms abutment. As the user continues to operate the liquid source 200 deeper into the receiving cavity 510 along the direction indicated by R3, it will press on the free end of the second rotating arm 620, causing the second rotating arm 620 to rotate around the pin 64 as indicated by arrow R41. Simultaneously, the second rotating arm 620 correspondingly drives the first rotating arm 610 to rotate around the pin 64 as indicated by arrow R42.

[0239] Further based on Figure 6 and Figure 9 As shown, the increased volume of the portion 621 is advantageous for increasing the contact or abutment area with the rigid outer wall 210 of the liquid source 200. Furthermore, during the operation where the liquid source 200 is partially received into the receiving cavity 510, the rotation direction R41 of the second rotating arm 620 is away from the proximal end 110, and the rotation direction R42 of the first rotating arm 610 is towards or near the proximal end 110.

[0240] Figure 7 A schematic diagram shows a second position in which the liquid source 200 is fully received within the receiving cavity 510. In this second position, the liquid source 200 abuts against the stop protrusion 54 to form a stop; the second rotating arm 620 is pressed by the liquid source 200 to engage or adhere to the inner surface of the container 50; and the free tip 611 of the first rotating arm 610 at least partially pierces the fractured wall 240 of the liquid source 200 and extends into the liquid storage cavity 250 to release the liquid matrix. In this embodiment, the first rotating arm 610 is relatively tilted and closer to the proximal end 110 than the second rotating arm 620. Furthermore, it can be seen from the figure that the rotation angle of the first rotating arm 610 and / or the second rotating arm 620 when rotating from the first position to the second position is less than 90 degrees.

[0241] exist Figure 9 In a more preferred embodiment, the extension length h3 of the second rotating arm 620 is longer than the extension length h2 of the first rotating arm 610. Based on a lever-like principle, when the user receives the liquid source 200 into the receiving cavity 510, it is easier to drive the rotation and puncture of the first rotating arm 610 by pressing the second rotating arm 620. In some preferred embodiments, the extension length h3 of the second rotating arm 620 is between 8 and 15 mm; the extension length h2 of the first rotating arm 610 is between 3 and 8 mm.

[0242] Based on the above, a lever is formed between the first rotating arm 610 and the second rotating arm 620 with the pin 64 as the fulcrum; and the second rotating arm 620 rotates with the pin 64 as the center or fulcrum under the drive of the first rotating arm 610. Of course, the actuation or movement of the first rotating arm 610 and the movement of the second rotating arm 620 are simultaneous or synchronous.

[0243] according to Figure 9 In the preferred embodiment shown, both the first spiral arm 610 and / or the second spiral arm 620 are elongated sheets. Furthermore, the length dimension of the first spiral arm 610 is greater than its width dimension, and the width dimension of the first spiral arm 610 is greater than its thickness dimension. Similarly, the length dimension of the second spiral arm 620 is greater than its width dimension, and the width dimension of the second spiral arm 620 is greater than its thickness dimension.

[0244] In some embodiments, the extension length h2 of the first rotating arm 610 ensures that the free front end 611 of the first rotating arm 610 is not abutted against or in contact with the outer wall 210 of the liquid source 200 during operation. Alternatively, the free front end 611 is configured with an arc-shaped or wedge-shaped cut to avoid the outer wall 210 of the liquid source 200.

[0245] See further Figure 10 As shown, the liquid transfer channel 520 includes:

[0246] The first section 5210 is close to and connected to the receiving cavity 510;

[0247] The second section 5220 is close to and connected to the atomizing mechanism 40.

[0248] Further in Figure 10 In the illustrated embodiment, the first segment 5210 and the second segment 5220 are substantially at an angle; according to the preferred embodiment shown in the figure, the first segment 5210 and the second segment 5220 form an obtuse angle greater than 90 degrees. Furthermore, the extension length of the first segment 5210 is greater than the extension length of the second segment 5220.

[0249] Furthermore, the inner diameter of at least part of the first section 5210 gradually decreases along the direction approaching the second section 5220; thus, the first section 5210 is generally constructed in a funnel shape. Also, the first section 5210 is substantially inclined, thus forming an angle with the length direction of the aerosol generating device 100.

[0250] Furthermore, at least a portion of the inner diameter of the first section 5210 gradually decreases in the direction approaching the second section 5220. Also, the first section 5210 is substantially inclined. Similarly, the vibratory element 42 is also arranged at an angle; thus, the vibratory element 42 forms an angle with the longitudinal direction of the aerosol generating device 100.

[0251] See further Figure 10 As shown, the vibrating element 42 of the atomizing mechanism 40, such as the piezoelectric ceramic sheet described above, is substantially perpendicular to the second section 5220.

[0252] See further Figure 10 As shown, the atomizing mechanism 40 also includes:

[0253] The first bracket 41 and the second bracket 43 clamp the vibrating element 42 from both sides to stably hold the vibrating element 42.

[0254] And further according to Figure 3 and Figure 10 Both the first support 41 and the second support 43 are approximately annular in shape. Specifically:

[0255] The first support 41 is arranged relatively close to the second section 5220 of the liquid transfer channel 520; and the annular central hole of the first support 41 is opposite to and communicates with the outlet of the second section 5220; for supplying the liquid matrix to the vibratory element 42 along the arrow R1 shown in the figure.

[0256] The second support 42 is arranged relatively close to the nozzle 20; the annular central hole of the second support 42 is connected to the internal aerosol output channel 23 of the nozzle 20; then the aerosol generated by the atomization of the liquid matrix by the vibrating element 42 is output to the aerosol output channel 23 of the nozzle 20 through the annular central hole of the second support 42 as shown by arrow R1 in the figure.

[0257] See further Figure 10 As shown, the upper housing 11 also defines a holding space 113 for accommodating and holding the atomizing mechanism 40; the atomizing mechanism 40 is substantially accommodated and held within the holding space 113.

[0258] Further in Figure 10In one embodiment shown, to facilitate a tight connection between the atomizing mechanism 40 and the liquid delivery channel 520, the first bracket 41 has at least a partially protruding connector 411; when the atomizing mechanism 40 is assembled into the holding space 113, the connector 411 at least partially surrounds and encloses the wall forming the second section 5220 to ensure stable assembly.

[0259] Figure 10 In one embodiment, a sealing element 5221 is also provided on the wall defining the second section 5220, which provides a seal for the joint gap when the joint portion 411 surrounds and encloses the wall forming the second section 5220.

[0260] Similarly, a sealing element 44 is also provided on the second bracket 42 to provide a seal between the inner wall of the retaining space 113 and the atomizing mechanism 40 when the atomizing mechanism 40 is assembled in the retaining space 113.

[0261] See after assembly. Figure 3 As shown, the connecting part 22 of the nozzle 20 abuts against the second bracket 42 of the atomizing mechanism 40. Of course, the atomizing mechanism 40 is not detachable after assembly.

[0262] For airflow during suction, see Figure 3 As shown, the nozzle has one or more air inlets 21 near the connection portion 22. External air enters the aerosol output channel 23 of the nozzle 20 through the air inlet 21 as indicated by arrow R2 in the figure, and carries the aerosol in the aerosol output channel 23 to the air inlet A for inhalation by the user.

[0263] See further Figure 11 As shown, the aerosol generating device 100 also includes:

[0264] The inner housing 13, together with the lower housing 12, defines a closed first space 123 substantially located within the lower housing 12; the first space 123 is a space for mounting the battery cell 150 and / or the circuit board 160. The inner housing 13 is at least partially surrounded by the lower housing 12, and a sealing element 133 is provided between them to provide a seal.

[0265] Furthermore, at least a portion of the inner housing 13 is also surrounded and enclosed by the upper housing 11; and a sealing element 132 is also provided between them to provide a seal between them.

[0266] Further in Figure 11In one embodiment, a second space 134 is further defined between the inner housing 13 and the upper housing 11; in practice, this second space 134 is a space for accommodating and assembling the container 50 and / or the atomizing mechanism 40. Furthermore, the inner housing 13 also has a boss 131 at least partially located within the upper housing 11; naturally, the boss 131 protrudes towards the proximal end 110. The container 50 is provided with screw holes 55 extending from its inner surface to its outer surface, and is connected to the boss 131 via screws 56 or similar fastening components passing through these screw holes 55; thereby ensuring that the container 50 is stably and securely mounted and held within the upper housing 11.

[0267] Furthermore, a flexible cap 57 is provided inside the screw hole 55, and after assembly, the cap 57 extends at least partially into the receiving cavity 510 of the container 50. The cap 57 covers or seals the screw hole 55 to prevent the screw 56 or similar fasteners from being exposed inside the container, thereby preventing the liquid matrix in the receiving cavity 510 from flowing towards the screw 56 and causing corrosion; on the other hand, the flexibility of the cap 57, when in contact with the liquid source 200, facilitates the receiving and removal of the liquid source 200.

[0268] Similarly, the container 50 is provided with a sealing element 58 between the portion of the container 50 that is joined to the upper housing 11 at the proximal end 110 to provide a seal between them.

[0269] In practice, the first space 123 is essentially sealed and airtight; the second space 134 is also essentially sealed and airtight. Furthermore, the first space 123 and the second space 134 are airtight with each other. During use, aerosols, liquid matrix, air, etc., from the surface of the housing or inside or outside the receiving cavity 510 are essentially unable to enter the first space 123.

[0270] In some embodiments, the upper housing 11, lower housing 12, and inner housing 13 are all configured to prevent disassembly by the user. They are essentially immovable and removable relative to each other, and similarly, the functional spaces they define are fixed in fixed positions relative to each other.

[0271] During use, the aerosol generating device 100 can be rinsed with water or washing liquid as a whole, and water or air cannot penetrate into the first space 123 during the rinsing process.

[0272] As can be seen from the diagram, the length of the first space 123 is longer than that of the second space 134.

[0273] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
