Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to an atomizer and an aerosol generation device. Background Technology

[0002] Aerosol generating devices are used to atomize an aerosol generating matrix to produce aerosols for user use. Currently, the aerosol generating matrix within these devices is susceptible to leakage due to factors such as temperature and pressure under various operating conditions, including environmental testing, transportation, and use. In related technologies, solving the leakage problem requires repeated adjustments and verifications of the atomizing core during development, impacting the product development cycle. Alternatively, some aerosol generating devices incorporate manual or electric valves to prevent leakage through core separation. However, manual valves require user operation, which can lead to users forgetting to close them, causing leakage, while electric valves are more expensive and have lower reliability.

Detailed Implementation

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0033] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0035] In related technologies, for example, when an aerosol generating device is in operation, the external atmospheric pressure is lower than the internal pressure, creating a positive pressure state inside the device. This can easily push the aerosol generating matrix outwards, leading to leakage. Similarly, when the aerosol generating device is in a high-temperature environment, the expansion of the internal gas increases the internal pressure, again making it prone to leakage under positive pressure. Furthermore, when the aerosol generating device is in use or transitions from a low-temperature to a high-temperature environment, the significant change in internal pressure from negative to positive can also easily cause leakage of the aerosol generating matrix.

[0036] This application provides an aerosol generating device, such as... Figures 1 to 4 As shown, the aerosol generating device may include an atomizer 1 and a power supply unit 2; the power supply unit 2 is electrically connected to the atomizer 1 and is used to supply power to the atomizer 1.

[0037] The power supply unit 2 may include a circuit board 21 and a battery cell 22. The atomizer 1 and the battery cell 22 are electrically connected to the circuit board 21, allowing the battery cell 22 to supply power to the atomizer 1 via the circuit board 21. To enrich the functionality of the aerosol generating device, the power supply unit 2 may also include electronic components such as a controller, a charging interface, and a display screen, all of which are electrically connected to the circuit board 21. For example, the controller can be used to control the atomization power of the atomizer 1, the charging interface can be used to connect an external power source to charge the battery cell 22, and the display screen can be used to display data such as the start / stop status of the aerosol generating device, atomization power, and remaining battery power. This application does not impose any special restrictions on the specific structure of the power supply unit 2.

[0038] It is understood that the aerosol generating device can be configured as a disposable product, i.e., the atomizer 1 and the power supply unit 2 are fixedly connected. Alternatively, the aerosol generating device can also be configured as a detachable product, i.e., the atomizer 1 and the power supply unit 2 can be configured as a detachable connection structure, allowing the user to replace the power supply unit 2 of the aerosol generating device according to usage needs. This application does not impose any special restrictions on the specific structural form of the aerosol generating device.

[0039] To address the leakage problem, this application also provides an atomizer 1, such as... Figures 2 to 4 As shown, the atomizer 1 may include a housing 4 and an atomizing core assembly 5. The housing 4 has a liquid storage chamber 41 for storing an aerosol generating matrix 3, and an air chamber 42 is defined between the aerosol generating matrix 3 and the cavity wall of the liquid storage chamber 41. The atomizing core assembly 5 is in liquid-conducting communication with the liquid storage chamber 41 and is used to atomize the aerosol generating matrix 3 to generate aerosol. The atomizing core assembly 5 has an atomization channel 51 and a ventilation channel 52. The atomization channel 51 is configured to communicate with the outside for aerosol discharge. One end of the ventilation channel 52 is connected to the atomization channel 51, and the other end of the ventilation channel 52 has at least two ventilation ports 521, which are connected to the liquid storage chamber 41. The air chamber 42 is configured to change its position within the liquid storage chamber 41 as the atomizer 1 is placed, and the air chamber 42 is configured to allow air to be circulated with the ventilation channel 52 through at least one ventilation port 521 when in different position states.

[0040] Thus, a portion of the reservoir 41 can be used to provide storage space for the aerosol generating matrix 3, while another portion of the reservoir 41 forms an air chamber 42 between the aerosol generating matrix 3 and the cavity wall of the reservoir 41. Depending on the placement of the atomizer 1, the air chamber 42 can be located at different positions within the reservoir 41. Since the atomization channel 51 of the atomizing core assembly 5 is connected to the outside, and one end of the ventilation channel 52 is connected to the atomization channel 51, while the other end of the ventilation channel 52 is connected to the reservoir 41 through the ventilation port 521, the pressure within the reservoir 41 can be maintained in balance with the pressure outside the atomizer 1 through the ventilation effect of the ventilation channel 52, thereby reducing the risk of leakage of the aerosol generating matrix 3. By providing at least two air vents 521 on the atomizing core assembly 5, the atomizer 1 can always maintain at least one air vent 521 connected to the air chamber 42 in different positions under different placement conditions. This allows the atomizer 1 to maintain the pressure balance inside and outside the liquid storage chamber 41 under different placement conditions, thereby reducing the problem of excessive pressure inside the liquid storage chamber 41 caused by different placement conditions, which could lead to leakage of the aerosol generation matrix 3.

[0041] This application provides a ventilation channel 52 on the atomizing core assembly 5, connecting the atomizing channel 51 and the liquid storage chamber 41. This allows the gas chamber 42 within the liquid storage chamber 41 to connect to the outside of the atomizer 1 via the ventilation channel 52 and ventilation ports 521. This enables the liquid storage chamber 41 to reduce the risk of leakage of the aerosol generating matrix 3 under various operating conditions by balancing the internal and external pressure difference. Compared to traditional technologies, this method eliminates the need for additional manual or electric valves, user operation, and is lower in cost and more reliable. Furthermore, by providing at least two ventilation ports 521 on the ventilation channel 52, the pressure difference between the inside and outside of the liquid storage chamber 41 can be maintained in different placement states of the atomizer 1, thereby reducing the risk of leakage in different placement states. Consequently, when conducting environmental testing of the aerosol generating device, there is no need for repeated adjustments and verification of the atomizing core, thus shortening the development cycle of the aerosol generating device.

[0042] It is understood that the ventilation channel 52 provided on the atomizing core assembly 5 in this application is not limited to venting the gas in the storage chamber 41 from the atomizer 1 when the storage chamber 41 is under positive pressure, but also includes guiding air from outside the atomizer 1 into the storage chamber 41 when the storage chamber 41 is under negative pressure. For example, when the user is using the aerosol generating device, as the liquid level of the aerosol generating matrix 3 drops, a negative pressure state may also be formed in the storage chamber 41. At this time, the ventilation channel 52 can also be used to introduce air from outside the atomizer 1 into the air chamber 42 of the storage chamber 41 to balance the pressure difference inside and outside the storage chamber 41, thereby making it easier for the aerosol generating matrix 3 to be atomized.

[0043] Furthermore, depending on the different appearance designs of the aerosol generating device, the housing 4 can be configured as a columnar, strip-shaped, or box-shaped structure. The structure of the housing 4 can be configured such that the shell body and bottom cover are detachably connected, or that the outer shell and inner shell are detachably connected. The liquid storage chamber 41 can be formed by the housing 4 to store liquid. For example, the aerosol generating device may also include a first sealing element 6 and a support 7. The support 7 is installed inside the housing 4 to divide the interior of the housing 4 into different installation spaces, allowing the atomizing core assembly 5 and the power supply unit 2 to be assembled in different installation spaces. The first sealing element 6 is installed between the support 7 and the housing 4, so that the first sealing element 6 and the housing 4 together enclose and form the liquid storage chamber 41. In other embodiments, an independent liquid storage tank structure can also be provided inside the housing 4 to form the liquid storage chamber 41. This application does not impose any special limitations on the specific structure of the housing 4.

[0044] In some embodiments, the ventilation channel 52 may be configured as a capillary channel.

[0045] By configuring the ventilation channel 52 as a capillary channel, it can adsorb the aerosol generating matrix 3 to a certain extent. When there is pressure in the liquid storage chamber 41, the aerosol generating matrix 3 can preferentially release pressure by flowing into the capillary channel, thereby reducing leakage caused by the aerosol generating matrix 3 flowing directly into the atomizing core assembly 5. The diameter of the capillary channel can be set to 0.5mm-1mm to enable the ventilation channel 52 to adsorb the aerosol generating matrix 3. This application does not impose any special limitations on the specific diameter of the capillary channel.

[0046] In some embodiments, such as Figures 1 to 4 As shown, the housing 4 has a height direction and a thickness direction, wherein two air vents 521 are arranged at intervals along the height direction of the housing 4, and / or wherein two air vents 521 are arranged at intervals along the thickness direction of the housing 4.

[0047] The aerosol generating device can have width, thickness, and height directions in the XYZ three-dimensional coordinate space. For ease of description, the following embodiments will use the X direction as the width direction, the Y direction as the thickness direction, and the Z direction as the height direction for illustrative purposes. By arranging two air exchange ports 521 at intervals along the Z direction of the housing 4, the gas chamber 42 in the liquid storage chamber 41 can be connected to the atomization channel 51 through at least one air exchange port 521 in both upright and inverted states. By arranging two air exchange ports 521 at intervals along the Y direction of the housing 4, the gas chamber 42 in the liquid storage chamber 41 can be connected to the atomization channel 51 through at least one air exchange port 521 in the state where the atomizer 1 is placed flat on both sides of the XZ plane. Therefore, the liquid storage chamber 41 of the atomizer 1 can be connected to the external air guide in different placement states, thereby reducing the risk of leakage of the aerosol generation matrix 3 caused by excessive pressure in the liquid storage chamber 41.

[0048] In some embodiments, such as Figure 5 and Figure 6 As shown, the atomizing core assembly 5 may include an atomizing tube 53 and an air exchange tube 54: the atomizing tube 53 is in liquid-conducting communication with the liquid storage chamber 41; the atomizing tube 53 has an atomizing channel 51; the air exchange tube 54 is disposed on the wall of the atomizing tube 53 facing the liquid storage chamber 41; the air exchange tube 54 has an air exchange channel 52.

[0049] By configuring the atomizing tube 53 and the ventilation tube 54 as detachable components, the ventilation tube 54 can be formed by hot bending or cold bending and assembled onto the wall of the atomizing tube 53 facing the liquid storage chamber 41, thereby reducing the assembly difficulty of the atomizing core assembly 5. In other embodiments, the ventilation tube 54 can also be assembled onto the wall of the atomizing tube 53 away from the liquid storage chamber 41. Alternatively, the ventilation tube 54 can be integrally formed onto the atomizing tube 53, i.e., the ventilation channel 52 is formed onto the tube wall of the atomizing tube 53. This application does not impose any special restrictions on the specific location of the ventilation tube 54 on the atomizing tube 53.

[0050] The atomizing core assembly 5 may include an atomizing element, which can atomize the aerosol generating matrix 3 into an aerosol by heating. For example, the atomizing element may include a heating element and an outer liquid guiding element. The heating element may be a resistance heating structure such as a heating mesh or heating element. The power supply unit 2 is electrically connected to the heating element to supply power, so that the heating element can generate heat when energized to heat the aerosol generating matrix 3. The outer liquid guiding element can be used to adsorb the aerosol generating matrix 3 for heating and atomization by the heating element. Alternatively, the atomizing element can also atomize the aerosol generating matrix 3 into an aerosol by ultrasonic high-frequency vibration. For example, the atomizing element may include an ultrasonic atomizing plate and a contact liquid guiding element. The power supply unit 2 is electrically connected to the ultrasonic atomizing plate to supply power, so that the ultrasonic atomizing plate can generate high-frequency vibration when energized to atomize the aerosol generating matrix 3. The contact liquid guiding element can be used to adsorb the aerosol generating matrix 3 for atomization by the ultrasonic atomizing plate. This application does not impose any special restrictions on the specific atomization method of the atomizing element. The atomizing element can be disposed inside the atomizing tube 53 and communicate with the liquid guide of the atomizing tube 53.

[0051] In some embodiments, such as Figures 5 to 8 As shown, the ventilation channel 52 may include a first ventilation channel 522 and a second ventilation channel 523; the ventilation tube body 54 may include a first ventilation tube 541 and a second ventilation tube 542. The first ventilation tube 541 has a first ventilation channel 522 and a first port 5221 and a second port 5222 communicating with the first ventilation channel 522. The first ventilation tube 541 is arranged along the wall of the atomizing tube body 53 and is connected to the atomizing channel 51 through the first port 5221. The second port 5222 is a ventilation port 521. The second ventilation tube 542 has a second ventilation channel 523 and a third port 5231 and a fourth port 5232 communicating with the second ventilation channel 523. The second ventilation tube 542 is arranged along the wall of the atomizing tube body 53 and is connected to the atomizing channel 51 through the third port 5231. The fourth port 5232 is another ventilation port 521.

[0052] Therefore, the first ventilation pipe 541 and the second ventilation pipe 542 can function as independent ventilation pipe bodies 54 for ventilation. That is, the air pressure inside the air chamber 42 can be released sequentially through the second port 5222, the first ventilation channel 522, and the first port 5221 into the atomizing channel 51. Alternatively, the air pressure inside the air chamber 42 can also be released sequentially through the fourth port 5232, the second ventilation channel 523, and the third port 5231 into the atomizing channel 51. The first ventilation channel 522 and the second ventilation channel 523 are independent of each other and do not interfere with each other, ensuring that the airflow does not become turbulent when the air chamber 42 in different positions exchanges air with the outside of the atomizer 1, thus ensuring the reliability of the ventilation.

[0053] In other embodiments, the ventilation tube 54 can also be configured as a structure in which a main ventilation channel 52 and two branch ventilation channels 52 are connected to each other, and the main ventilation channel 52 is connected to the atomization channel 51. The two ventilation ports 521 are respectively provided on the two branch ventilation channels 52, which can also allow the air chamber 42 in different positions to exchange air with the outside of the atomizer 1. This application does not impose any special restrictions on the specific structural form of the ventilation tube 54.

[0054] In some embodiments, such as Figures 5 to 8 As shown, the atomizer 1 may also include a mouthpiece 8, which is connected to the housing 4 and communicates with the atomization channel 51 for airflow; the second port 5222 is located close to the mouthpiece 8, and the fourth port 5232 is located away from the mouthpiece 8.

[0055] For example, when the aerosol generating device is placed upright, i.e., its placement surface is the XY plane and the nozzle 8 faces upwards, the aerosol generating matrix 3 is away from the nozzle 8, and the gas chamber 42 is close to the nozzle 8. At this time, the first port 5221 of the first ventilation pipe 541 is connected to the atomization channel 51 of the atomizing tube 53, and the second port 5222 of the first ventilation pipe 541 is located inside the liquid storage chamber 41 on the side close to the nozzle 8. This allows the gas chamber 42 to connect with the atomization channel 51 through the second port 5222 and the first ventilation channel 522, thereby balancing the pressure difference inside and outside the liquid storage chamber 41. Similarly, when the aerosol generating device is placed upside down, i.e., its placement surface is the XY plane and the nozzle 8 faces downwards, the aerosol generating matrix 3 is close to the nozzle 8, and the gas chamber 42 is away from the nozzle 8. At this time, the third port 5231 of the second air exchange pipe 542 is connected to the atomization channel 51 of the atomization tube body 53, and the fourth port 5232 of the second air exchange pipe 542 is located on the side of the liquid storage chamber 41 away from the nozzle 8, so that the air chamber 42 can be connected to the atomization channel 51 through the fourth port 5232 and the second air exchange channel 523, which can also balance the pressure difference inside and outside the liquid storage chamber 41.

[0056] Therefore, when the aerosol generating device is placed upright or upside down on the XY plane, the liquid storage chamber 41 can be connected to the outside of the atomizer 1 through the first ventilation pipe 541 or the second ventilation pipe 542, so that the liquid storage chamber 41 can maintain the internal and external air pressure balance when the atomizer 1 is in different placement states, thereby reducing the risk of leakage of the aerosol generating matrix 3.

[0057] In some embodiments, such as Figure 9 As shown, the first ventilation pipe 541 may include a first pipe segment 5411, a second pipe segment 5412, and a third pipe segment 5413 connected in sequence; the second pipe segment 5412 extends circumferentially along the atomizing pipe body 53, and its two ends are respectively connected to the first pipe segment 5411 and the third pipe segment 5413; both the first pipe segment 5411 and the third pipe segment 5413 extend toward the nozzle 8; the first pipe segment 5411 is located on the side of the atomizing pipe body 53 away from the third pipe segment 5413; the first port 5221 is opened at the end of the first pipe segment 5411 away from the second pipe segment 5412, and the second port 5222 is opened at the end of the third pipe segment 5413 away from the second pipe segment 5412.

[0058] The axial directions of the first tube segment 5411 and the third tube segment 5413 can be parallel to the axial direction of the atomizing tube body 53. By setting the first tube segment 5411 and the third tube segment 5413 on the atomizing tube body 53, and placing the second tube segment 5412 on the side away from the nozzle 8, the path length of the first ventilation tube 541 can be increased, thereby making it less likely for the aerosol generating matrix 3 in the liquid storage chamber 41 to leak from the first ventilation tube 541. In addition, when the aerosol generating device is inverted, even if some of the aerosol generating matrix 3 in the liquid storage chamber 41 flows into the second port 5222, the aerosol generating matrix 3 cannot climb from the third tube segment 5413 to the second tube segment 5412 under the action of gravity, thereby reducing the risk of leakage of the aerosol generating matrix 3. Furthermore, by placing the first tube segment 5411 and the third tube segment 5413 on opposite sides of the atomizing tube body 53, the first port 5221 and the second port 5222 can be located on opposite sides of the atomizing tube body 53. The first tube segment 5411 and the third tube segment 5413 can be set to the same length, so that the first port 5221 and the second port 5222 can be located at the same height of the atomizing tube body 53, and the first port 5221 and the second port 5222 can be as close as possible to the nozzle 8, so that the air pressure inside and outside the liquid storage chamber 41 can be quickly balanced through the first air exchange tube 541. This application does not impose any special restrictions on the specific lengths of the first tube segment 5411, the second tube segment 5412, and the third tube segment 5413.

[0059] In some embodiments, such as Figure 9As shown, the second ventilation pipe 542 may include a fourth pipe segment 5421 and a fifth pipe segment 5422; the fifth pipe segment 5422 is disposed away from the mouthpiece 8, extends circumferentially along the atomizing tube body 53, and is connected to the fourth pipe segment 5421; the fourth pipe segment 5421 extends toward the mouthpiece 8, and is disposed on the side of the atomizing tube body 53 away from the first pipe segment 5411; the third port 5231 is opened at the end of the fourth pipe segment 5421 away from the fifth pipe segment 5422, and is also opened on the side of the atomizing tube body 53 away from the first port 5221; the fourth port 5232 is opened at the end of the fifth pipe segment 5422 away from the fourth pipe segment 5421, and is also opened on the side of the atomizing tube body 53 away from the third port 5231.

[0060] For example, when the aerosol generating device is placed horizontally, i.e., when the placement surface of the aerosol generating device is the XZ plane, the aerosol generating matrix 3 is located on the lower side of the atomizing tube 53, and the gas chamber 42 is located on the upper side of the atomizing tube 53. Since the third port 5231 is located on the opposite side of the first port 5221, and the fourth port 5232 is located on the opposite side of the third port 5231, at least one of the second port 5222 and the fourth port 5232 can be located inside the gas chamber 42, so that the gas chamber 42 can still be connected to the outside of the atomizer 1 through the first air exchange pipe 541 or the second air exchange pipe 542, thereby balancing the pressure difference inside and outside the liquid storage chamber 41.

[0061] Specifically, when the aerosol generating matrix 3 is located on one side of the first port 5221 and the gas chamber 42 is located on one side of the second port 5222, the gas in the gas chamber 42 can flow from the second port 5222 into the atomization channel 51 through the first air exchange pipe 541 from the first port 5221. Figure 8 The gas flows into the aerosol generating device (as indicated by the solid arrow in the middle) to release pressure and balance the pressure difference in the storage chamber 41. When the aerosol generating matrix 3 is located on one side of the third port 5231 and the gas chamber 42 is located on one side of the fourth port 5232, the gas in the gas chamber 42 can flow from the third port 5231 into the atomization channel 51 through the second air exchange pipe 542 via the fourth port 5232. Figure 8 The airflow direction indicated by the hollow arrow can also be discharged outside the aerosol generating device to relieve pressure and balance the pressure difference in the storage chamber 41. Therefore, regardless of which side of the XZ plane the aerosol generating device is placed on, the storage chamber 41 can still be connected to the outside of the atomizer 1 through the first ventilation pipe 541 or the second ventilation pipe 542. This ensures that the storage chamber 41 maintains internal and external pressure balance in different placement states, reducing the risk of leakage of the aerosol generating matrix 3.

[0062] The axial direction of the fourth tube segment 5421 can be parallel to the axial direction of the atomizing tube body 53. Similarly, by placing the third port 5231 closer to the nozzle 8 and the fifth tube segment 5422 further away from the nozzle 8, the path length of the second ventilation tube 542 can be increased, thus making it less likely for the aerosol generating matrix 3 in the liquid storage chamber 41 to leak from the second ventilation tube 542. Furthermore, when the aerosol generating device is placed upright, even if some of the aerosol generating matrix 3 in the liquid storage chamber 41 flows into the fourth port 5232, the aerosol generating matrix 3 cannot rise from the fourth tube segment 5421 to the third port 5231 under the action of gravity, thereby reducing the risk of leakage of the aerosol generating matrix 3. The fourth port 5232 can be located as far away from the nozzle 8 as possible. The third port 5231 and the first port 5221 can be located on the same cross-section of the atomizing tube 53 (the cross-section is perpendicular to the axis of the atomizing tube 53), so that both the third port 5231 and the first port 5221 are close to the nozzle 8. This allows the air pressure inside and outside the liquid storage chamber 41 to be quickly balanced through the second ventilation pipe 542, and the aerosol generation matrix 3 inside the liquid storage chamber 41 is less likely to leak from inside or outside the second ventilation pipe 542. This application does not impose any special restrictions on the specific lengths of the fourth pipe segment 5421 and the fifth pipe segment 5422.

[0063] Furthermore, the second tube segment 5412 can be positioned closer to the nozzle 8 than the fifth tube segment 5422, or it can be positioned further away from the nozzle 8 than the fifth tube segment 5422, or it can be positioned on the same cross-section of the atomizing tube body 53 as the fifth tube segment 5422 (the cross-section is perpendicular to the axis of the atomizing tube body 53). This application does not impose any special restrictions on the relative positional relationship between the second tube segment 5412 and the fifth tube segment 5422. To extend the length of the first air exchange tube 541 and the second air exchange tube 542, the first air exchange tube 541 and the second air exchange tube 542 can also be arranged in a spiral or serpentine pattern on the atomizing tube body 53. This application does not impose any special restrictions on the specific shape of the first air exchange tube 541 and the second air exchange tube 542 on the atomizing tube body 53.

[0064] Therefore, by placing the second port 5222 and the third port 5231 on the opposite side of the first port 5221, and the fourth port 5232 on the opposite side of the third port 5231, the air pressure in the storage chamber 41 can be exchanged through the spaced arrangement of the second port 5222 and the fourth port 5232 along the axial direction of the atomizing tube 53 when the aerosol generating device is placed upright or upside down. When the aerosol generating device is placed horizontally, the air pressure in the storage chamber 41 can be exchanged through the spaced arrangement of the second port 5222 and the fourth port 5232 along the radial direction of the atomizing tube 53. Thus, by providing only two ventilation channels 52 on the atomizing tube 53, this application can achieve internal and external air pressure balance when the aerosol generating device is placed upright, upside down, or horizontally, thereby reducing the risk of leakage of the aerosol generating matrix 3.

[0065] In other embodiments, to maintain pressure balance inside and outside the liquid storage chamber 41 in other placement states of the aerosol generating device, a third, fourth, or more ventilation pipes 54 can be provided on the atomizing tube 53 to achieve pressure balance inside and outside the aerosol generating device in more placement states. This application does not impose any special limitation on the specific number of ventilation pipes 54 provided on the atomizing tube 53.

[0066] In some embodiments, such as Figure 10 As shown, the atomizing tube body 53 is provided with a connecting chamber 531 and a first mounting hole 532 and a second mounting hole 533 communicating with the connecting chamber 531; a first air exchange pipe 541 is installed in the first mounting hole 532, and a first port 5221 is connected to the connecting chamber 531; a second air exchange pipe 542 is installed in the second mounting hole 533, and a third port 5231 is connected to the connecting chamber 531; the atomizing tube body 53 is also provided with a through hole 534, and the connecting chamber 531 is connected to the atomizing channel 51 through the through hole 534.

[0067] Therefore, both the first ventilation channel 522 and the second ventilation channel 523 can be connected to the through hole 534 through the connecting chamber 531, thereby connecting the first ventilation channel 522 and the second ventilation channel 523 to the atomization channel 51. In addition, when the first ventilation pipe 541 and the second ventilation pipe 542 are exchanging air, and some of the aerosol generating matrix 3 flows into the ventilation channel 52 with the gas flow, the connecting chamber 531 can also serve as a buffer space for the aerosol generating matrix 3, so that the aerosol generating matrix 3 is retained in the connecting chamber 531, thereby preventing the aerosol generating matrix 3 from leaking directly out from the through hole 534.

[0068] Furthermore, since the ventilation channel 52 is a capillary channel, it can adsorb a certain amount of aerosol generating matrix 3. When the XZ plane of the aerosol generating device is laid flat, if the aerosol generating matrix 3 is located on one side of the first port 5221 and the gas chamber 42 is located on one side of the second port 5222, the aerosol generating matrix 3 can flow from the fourth port 5232 into the second ventilation pipe 542 under capillary action, and the aerosol generating matrix 3 can climb along the second ventilation pipe 542 to the third port 5231. At this time, since the first port 5221 is also connected to the third port 5231 through the connecting chamber 531, the aerosol generating matrix 3 can flow from the third port 5231 into the first port 5221 through the connecting chamber 531, thereby causing the aerosol generating matrix 3 to flow from the first port 5221 into the first ventilation pipe 541. Therefore, the aerosol generating matrix 3 in the first ventilation pipe 541 can act as a liquid seal for the first ventilation channel 522, preventing the second port 5222 from communicating with the air chamber 42. This prevents the first ventilation pipe 541 from communicating with the outside of the atomizer 1. Furthermore, both the first ventilation pipe 541 and the second ventilation pipe 542 are liquid-sealed by the aerosol generating matrix 3, and the aerosol generating matrix 3 in the liquid storage chamber 41 no longer climbs along the second ventilation pipe 542. This achieves the self-locking function of the first ventilation channel 522, reducing the risk of leakage of the aerosol generating matrix 3. If the aerosol generating matrix 3 is located on the side of the third port 5231 and the air chamber 42 is located on the side of the fourth port 5232, the aerosol generating matrix 3 can flow from the second port 5222 into the first ventilation pipe 541 under capillary action, and the aerosol generating matrix 3 climbs along the first ventilation pipe 541 to the first port 5221. At this time, since the first port 5221 is also connected to the third port 5231 through the connecting chamber 531, the aerosol generating matrix 3 can flow from the first port 5221 through the connecting chamber 531 into the third port 5231, thereby allowing the aerosol generating matrix 3 to flow from the third port 5231 into the second ventilation pipe 542. Similarly, the aerosol generating matrix 3 in the second ventilation pipe 542 can act as a liquid seal for the second ventilation channel 523, preventing the fourth port 5232 from connecting with the air chamber 42. This prevents the second ventilation pipe 542 from connecting to the outside of the atomizer 1. Furthermore, since both the first ventilation pipe 541 and the second ventilation pipe 542 are liquid-sealed by the aerosol generating matrix 3, the aerosol generating matrix 3 in the liquid storage chamber 41 no longer climbs along the first ventilation pipe 541, thus achieving the self-locking function of the second ventilation channel 523.

[0069] This application provides a connecting chamber 531 on the atomizing tube 53, which not only serves to temporarily store the aerosol generating matrix 3, but also connects the first ventilation pipe 541 and the second ventilation pipe 542. This allows the first ventilation pipe 541 and the second ventilation pipe 542 to self-lock through the liquid seal of the aerosol generating matrix 3 when the aerosol generating device is placed flat, thereby reducing the risk of leakage of the aerosol generating matrix 3.

[0070] In some embodiments, such as Figure 10 and Figure 11 As shown, the connecting chamber 531 is located near the nozzle 8 of the atomizing tube 53; and / or, a plurality of through holes 534 are evenly arranged along the circumference of the atomizing tube 53, and the aperture of each through hole 534 is configured such that the aerosol generating matrix 3 can block the through hole 534 under the action of liquid tension.

[0071] Since the aerosol generating device is mostly placed upright, by positioning the connecting chamber 531 near the nozzle 8 on the atomizing tube 53, the connecting chamber 531 can be located within the gas chamber 42 in most cases, thereby improving the leak-proof performance of the atomizer 1. Furthermore, when the connecting chamber 531 is positioned near the nozzle 8, the height of the first port 5221 and the third port 5231 along the Z-direction can be increased, making it less likely for the aerosol generating matrix 3 to flow into the connecting chamber 531 under capillary action. The ventilation efficiency of the ventilation channel 52 can be improved by providing multiple through holes 212 circumferentially on the atomizing tube 53. Moreover, when the aerosol generating matrix 3 flows into the connecting chamber 531, under low ventilation pressure, the aerosol generating matrix 3 can form a liquid seal at the through hole 534 under liquid tension, preventing leakage of the aerosol generating matrix 3 from the through hole 534. When the ventilation pressure is high, the through hole 534 can be opened for ventilation. For example, the diameter of the through hole 534 can be set to 0.3mm-0.5mm. This application does not impose any special restrictions on the diameter of the through hole 534.

[0072] In some embodiments, such as Figure 3 and Figure 4As shown, the atomizing tube 53 may include an outer tube 535, an inner tube 536, a liquid guiding element 537, and a liquid suction element 538; the outer tube 535 is sleeved on the outside of the inner tube 536, and the side of the outer tube 535 away from the nozzle 8 is provided with a liquid inlet 5350, and the side of the inner tube 536 away from the nozzle 8 is provided with a liquid outlet 5360; the liquid guiding element 537 is disposed between the outer tube 535 and the inner tube 536 to adsorb aerosols from the liquid inlet 5350 to generate matrix 3. Liquid is supplied through the liquid passage 5360; the liquid suction element 538 is located between the outer tube 535 and the inner tube 536, and is set close to the suction nozzle 8; the first assembly hole 532 and the second assembly hole 533 are set in the outer tube 535, and the through hole 534 is set in the inner tube 536; the liquid suction element 538, the liquid guide element 537, the outer tube 535 and the inner tube 536 together form a communicating chamber 531, and the first port 5221 and the third port 5231 are both spaced apart from the inner tube 536.

[0073] When using the aerosol generating device, the liquid guide 537 can absorb the aerosol generating matrix 3 in the storage chamber 41 through the liquid inlet 5350 on the outer tube 535. The atomizing element is sleeved in the inner tube 536 and absorbs the aerosol generating matrix 3 in the liquid guide 537 through the liquid passage 5360 on the inner tube 536, so that the atomizing element can atomize and generate aerosol. The aerosol can be discharged from the atomizing channel 51 through the nozzle 8 outside the aerosol generating device for user use. The first ventilation pipe 541 and the second ventilation pipe 542 are respectively connected to the first mounting hole 532 and the second mounting hole 533 on the outer tube 535, so that the outer tube 535 can support and fix the first ventilation pipe 541 and the second ventilation pipe 542.

[0074] The outer tube 535 can be provided with multiple liquid inlet holes 5350 in its circumferential direction, and the inner tube 536 can be provided with multiple liquid outlet holes 5360 in its circumferential direction. This allows the aerosol generating matrix 3 in the liquid storage chamber 41 to flow into the atomizing element from different directions, ensuring the stability and reliability of the liquid supply from the liquid storage chamber 41 to the atomizing element. This application does not impose any special limitation on the specific number of liquid inlet holes 5350 and liquid outlet holes 5360. Furthermore, both the liquid inlet holes 5350 and liquid outlet holes 5360 are located on the side of the atomizing tube 53 away from the nozzle 8, making it easier for the aerosol generating matrix 3 in the liquid storage chamber 41 to flow into the atomizing element.

[0075] The suction element 538 can be used to absorb the aerosol generating matrix 3 or condensate at the nozzle 8 to reduce the risk of leakage of the aerosol generating matrix 3 or condensate from the nozzle 8. Furthermore, the aerosol generating device may also include a second seal 9 connected between the atomizing tube 53 and the nozzle 8 to seal the gap between them, thereby reducing the risk of leakage of the aerosol generating matrix 3 or condensate from the nozzle 8.

[0076] In some embodiments, the conduction resistance of the ventilation channel 52 is less than the liquid conduction resistance of the atomizing core assembly 5.

[0077] By setting the conduction resistance of the ventilation channel 52 to be less than the liquid guiding resistance of the atomizing core assembly 5, when the gas pressure in the gas chamber 42 is high, the gas is preferentially discharged from the atomizer 1 through the ventilation channel 52 for pressure relief, rather than being discharged from the atomizer 1 through the liquid guiding component 537 and the atomizing component. This reduces the problem of leakage of the aerosol generation matrix 3 from the atomizing component. The conduction resistance of the ventilation channel 52 can be set by configuring the number and path of the ventilation tubes 54. For example, the more ventilation tubes 54 there are, the lower the conduction resistance of the ventilation channel 52. Alternatively, the shorter the path of the ventilation tubes 54, the lower the conduction resistance of the ventilation channel 52. This application does not impose any special restrictions on the specific number and path length of the ventilation tubes 54.

[0078] In some embodiments, such as Figure 12 As shown, the cross-sectional shape of the shell 4 can be set to a rectangle, a waist shape or an ellipse, and the cross-section is perpendicular to the axis of the atomizing tube 53.

[0079] For example, when the housing 4 is laid flat, it can have a first placement surface 43. Since rectangular, waist-shaped, or elliptical cross-sections all have a major axis and a minor axis, when the first placement surface 43 of the aerosol generating device is laid flat, the first port 5221 and the third port 5231 are arranged opposite each other in the Y direction, and the second port 5222 and the fourth port 5232 are arranged opposite each other in the Y direction, so that either the first ventilation pipe 541 or the second ventilation pipe 542 can communicate with the air chamber 42. In other embodiments, the cross-sectional shape of the housing 4 can also be set as a square. Since the dimensions of the major axis and the minor axis are the same in the square, the aerosol generating device can also be laid flat on the second placement surface 44. At this time, a third ventilation pipe and a fourth ventilation pipe can be added inside the aerosol generating device, and the third ventilation pipe and the fourth ventilation pipe can be arranged opposite each other in the X direction, so that when the aerosol generating device is laid flat on the second placement surface 44, the liquid storage chamber 41 can still communicate with the outside of the atomizer 1 through the ventilation channel 52. This application does not impose any special restrictions on the specific location and number of the ventilation pipe body 54.
