[0002] An aerosol generator is a device that uses control circuits and atomizing elements to control its operating state and vapor output for user use. The aerosol generator includes an atomizer, which has multiple sealing points. In related technologies, these multiple sealing points are difficult to achieve with a single component, resulting in a large number of sealing components and a complex atomizer structure. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide an atomizer and an aerosol generating device, which are intended to simplify the structure of the atomizer.

[0004] To solve the above problems, the technical solution of this application embodiment is implemented as follows: This application provides an atomizer, including: The housing has a cavity and an air outlet channel; The atomizing base is at least partially disposed in the cavity; The atomizing core has a first end and a second end disposed opposite to each other, and an inner cavity penetrating the first end and the second end, the inner cavity being in fluid communication with the air outlet channel; A sealing element defines a liquid storage chamber with the cavity wall of the cavity, and the sealing element has a liquid passage hole that is in fluid communication with both the liquid storage chamber and the atomizing core; The sealing element comprises an integrally formed first part and a second part. The first part is sealed to the cavity wall of the cavity, and the second part is sealed between the side wall of the air outlet channel and the second end. The axis of the liquid passage is parallel to the axis of the second part.

[0005] In some embodiments, the atomizer seat has a mounting groove, at least a portion of the first end is located within the mounting groove, and the liquid passage is in fluid communication with the atomizer core through the mounting groove.

[0006] In some embodiments, the atomizer includes a liquid reservoir located within the mounting groove and surrounding the atomizing core.

[0007] In some embodiments, the mounting groove includes a first groove and a second groove that are axially connected and aligned with the atomizing core, the atomizing core passing through the second groove and inserted into the first groove, and the liquid storage component being located in the second groove.

[0008] In some embodiments, the atomizing seat has a ventilation channel and a first air intake channel, one end of the first air intake channel is connected to the outside atmosphere, the other end is connected to the inner cavity and the ventilation channel, and the other end of the ventilation channel is connected to the liquid storage tank.

[0009] In some embodiments, the ventilation channel includes a groove located on the surface of the atomizing seat; and / or, The atomizing seat has an annular column that surrounds and forms at least a portion of the first air intake channel, and the top surface of the annular column is higher along the axial direction of the atomizer than the end of the ventilation channel that communicates with the first air intake channel.

[0010] In some embodiments, the atomizing seat has a second air intake channel, the first air intake channel being connected to the outside atmosphere through the second air intake channel, and the axial direction of the first air intake channel and the axial direction of the second air intake channel being set at an angle.

[0011] In some embodiments, the seal and the atomizing seat are arranged to form an air intake cavity, which surrounds the outer periphery of the first air intake channel, and the second air intake channel extends radially along the first air intake channel and its two ends are respectively connected to the air intake cavity and the first air intake channel.

[0012] In some embodiments, the seal further includes an integrally formed third portion located on the side of the air inlet chamber away from the liquid storage tank, and the third portion is sealed between the atomizing seat and the inner wall of the housing.

[0013] This application provides an aerosol generating apparatus, comprising: Power supply components; The atomizer described in any of the above embodiments is electrically connected to the power supply assembly.

[0014] In the atomizer of this application embodiment, since the axis of the liquid passage hole and the axis of the second part are parallel, when the seal is constructed as an integral structure, it can be molded along the axial direction of the liquid passage hole, thereby forming the liquid passage hole and the second part. This type of seal does not affect the complexity of mold processing and facilitates the seal to be set as an integrally molded structure. The integrally molded seal seals the gap between the atomizing seat and the housing through the first part, and at the same time, it can also seal the gap between the atomizing core and the side wall of the air outlet channel through the second part. That is, a single seal can achieve multiple seals at the same time, which helps to reduce the number of parts of the atomizer, thereby simplifying the structure of the atomizer.

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] This application provides an atomizer; please refer to [link / reference]. Figures 1 to 5 The atomizer 10 includes a housing 11, an atomizing core 13, an atomizing base 12, and a sealing element 14.

[0025] Furthermore, this application also provides an aerosol generating apparatus; please refer to [link to relevant documentation]. Figures 1 to 5 The aerosol generating device includes a power supply assembly and an atomizer 10 according to any embodiment of this application.

[0026] It should be noted that when the aerosol generating device adopts the atomizer 10 of any embodiment of this application, the aerosol generating device has all the advantages of the atomizer 10 of the corresponding embodiment, and the specific advantages are described in detail below.

[0027] The power supply component is mainly used to supply power to the atomizer 10 and control the opening and closing of the entire aerosol generation device. The atomizer 10 is mainly used to contain the aerosol generation matrix and heat and atomize the aerosol generation matrix after being powered on.

[0028] In some embodiments, the atomizer 10 and the power supply assembly can be mechanically and electrically connected together axially. Further, the atomizer 10 and the power supply assembly can be connected together in a detachable manner via magnetic connection, threaded connection, snap-fit ​​connection, or other similar methods. Both the atomizer 10 and the power supply assembly can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer 10 and the power supply assembly can also be connected together in a non-detachable manner.

[0029] Furthermore, the atomizer 10 and / or power supply assembly are not limited to being cylindrical; they can also be other shapes such as elliptical or square cylindrical.

[0030] Please see Figure 1 and Figure 2 The housing 11 has a cavity 11a and an air outlet channel 11b; at least a portion of the atomizing seat 12 is disposed in the cavity 11a; the atomizing core 13 has a first end 13b and a second end 13c disposed opposite to each other, and an inner cavity 13a penetrating the first end 13b and the second end 13c, the inner cavity 13a being in fluid communication with the air outlet channel 11b; the sealing member 14 and the cavity wall of the cavity 11a define a liquid storage chamber 10a, and the sealing member 14 has a liquid passage hole 14a, which is in fluid communication with both the liquid storage chamber 10a and the atomizing core 13.

[0031] Here, the user draws in aerosol through the air outlet channel 11b.

[0032] In some embodiments, please refer to Figure 2 The air outlet channel 11b extends along the height direction of the atomizer 10. It should be noted that, in the embodiments of this application, the height direction of the atomizer 10 should be understood as the orientation and direction of the atomizer 10 when it is in normal use posture and placed on a horizontal plane, and the height direction of the atomizer 10 is also the axial direction of the atomizer 10.

[0033] In some embodiments, please refer to Figure 2 The bottom side of the cavity 11a is open, and at least a portion of the atomizing seat 12 is located on the open side of the cavity 11a.

[0034] The liquid storage chamber 10a is used to store the aerosol generation matrix. The fact that the liquid passage 14a is in fluid communication with both the liquid storage chamber 10a and the atomizing core 13 means that the aerosol generation matrix in the liquid storage chamber 10a can be guided to the atomizing core 13 through the liquid passage 14a.

[0035] The atomizing core 13 is electrically connected to the power supply component. The atomizing core 13 can convert electrical energy into other forms of energy and apply them to the aerosol generating matrix, thereby atomizing the aerosol generating matrix and generating aerosol.

[0036] The atomizer base 12 provides an installation base for the atomizer core 13, and the atomizer base 12 can also support the seal 14 so that the seal 14 and the cavity wall of the cavity 11a are sealed together to define the liquid storage chamber 10a.

[0037] It should be noted that there are no restrictions on the specific way the atomizer core 13 is placed on the atomizer base 12.

[0038] In some embodiments, please refer to Figure 2 and Figure 4 The atomizer base 12 has a mounting groove 12m, with at least a portion of the first end 13b located within the mounting groove 12m. A liquid passage 14a is in fluid communication with the atomizer core 13 through the mounting groove 12m. The aerosol generation matrix within the liquid passage 14a can be guided to the atomizer core 13 through the mounting groove 12m. By providing the mounting groove 12m, the atomizer base 12 facilitates the insertion of the first end 13b of the atomizer core 13 into the interior of the atomizer base 12, thereby improving the installation stability and reliability of the atomizer core 13 on the atomizer base 12.

[0039] In other embodiments, the atomizer base 12 may not have a mounting groove 12m, and one end 13b of the atomizer core 13 may be directly disposed on the outer surface of the atomizer base 12 or disposed on the atomizer base 12 through other components.

[0040] The specific structure of the atomizer core 13 is not limited.

[0041] In some embodiments, please refer to Figure 2 The atomizing core 13 includes a body and a heating element 131. The body surrounds an inner cavity 13a, and the heating element 131 is disposed in the inner cavity 13a. The heating element 131 is electrically connected to a power supply assembly. The heating element 131 converts electrical energy into other forms of energy and acts on the aerosol generating matrix to heat and atomize the aerosol generating matrix, thereby generating an aerosol. The body includes a liquid guiding element that transmits or delivers the aerosol generating matrix to the heating element 131, for example, through capillary action or other forces. The material of the liquid guiding element includes, but is not limited to, non-woven fabric, cotton, ceramic, glass, quartz, or fiber.

[0042] The specific method by which the heating element 131 heats the aerosol to generate the matrix is ​​not limited. For example, it can be resistance heating, electromagnetic induction heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, plasma heating, etc.

[0043] Specifically, the heating element 131 that uses resistance heating is called a heating element. The heating element can convert electrical energy into heat energy, thereby heating the aerosol generation matrix to generate aerosols.

[0044] There are no restrictions on the specific type of heating element. For example, it can be a heating needle, heating film, heating mesh, heating plate, or heating wire, etc.

[0045] Please see Figure 2 and Figure 3 The sealing element 14 includes an integrally formed first part 141 and a second part 142. The first part 141 is sealed to the cavity wall of the cavity 11a, and the second part 142 is sealed between the side wall of the air outlet channel 11b and the second end 13c. The axis of the liquid passage 14a is parallel to the axis of the second part 142.

[0046] Specifically, the axis of the liquid passage 14a and the axis of the second part 142 are both parallel to the axis of the air outlet channel 11b. Furthermore, the axes of all three can be parallel to the height direction of the atomizer 10.

[0047] The first part 141 helps to increase the gap between the seal 14 and the cavity wall of the cavity 11a, thereby improving the sealing performance of the liquid storage tank 10a.

[0048] The specific shape of the second part 142 is not limited. For example, it can be various ring shapes such as a circular ring. Specifically, the shape of the second part 142 can match the cross-sectional shape of the air outlet channel 11b and the cross-sectional shape of the second end 13c of the atomizing core 13, which is beneficial to improving the sealing performance between the sidewall of the air outlet channel 11b and the atomizing core 13.

[0049] It should be noted that, in the embodiments of this application, the cross-section of any component refers to the cross-section perpendicular to its axial direction. For example, the cross-section of the air outlet channel 11b refers to the cross-section of the air outlet channel 11b obtained by cutting the air outlet channel 11b with a plane perpendicular to its axial direction.

[0050] The gap between the side wall of the air outlet channel 11b and the atomizing core 13 is sealed by the second part 142. This makes it easier for the user to draw out the aerosol generated in the atomizing core 13. At the same time, it also helps to reduce the probability that the aerosol generation matrix in the liquid storage chamber 10a will enter the air outlet channel 11b through this gap and cause leakage in the air outlet channel 11b.

[0051] In summary, in the atomizer 10 of this application embodiment, since the axis of the liquid passage 14a and the axis of the second part 142 are parallel, when the seal 14 is constructed as an integral structure, it can be demolded along the axial direction of the liquid passage 14a, thereby forming the liquid passage 14a and the second part 142. This type of seal 14 does not affect the complexity of mold processing, making it easy for the seal 14 to be set as an integrally formed structure. The integrally formed seal 14 seals the gap between the atomizing seat 12 and the housing 11 through the first part 141, and at the same time, it can also seal the gap between the atomizing core 13 and the side wall of the air outlet channel 11b through the second part 142. That is, a single seal 14 can achieve multiple seals at the same time, which helps to reduce the number of parts of the atomizer 10, thereby simplifying the structure of the atomizer 10.

[0052] Furthermore, in the atomizer 10 of this application embodiment, the atomizing core 13 can be disposed inside the integral component formed by the atomizing seat 12 and the sealing member 14. Therefore, during the assembly of the atomizer 10, the atomizing seat 12, the atomizing core 13 and the sealing member 14 can be assembled into an integral whole first. After injecting aerosol into the cavity 11a to generate a matrix, the integral whole formed by the atomizing seat 12, the atomizing core 13 and the sealing member 14 can be assembled with the shell 11. In this way, the assembly method of the atomizer 10 is simpler, which is conducive to improving the assembly efficiency of the atomizer 10, thereby improving the production efficiency of the atomizer 10.

[0053] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The atomizer 10 includes a liquid reservoir 16, which is located within the mounting groove 12m and surrounds the atomizing core 13. That is, the liquid reservoir 16 surrounds the outer periphery of the atomizing core 13.

[0054] The aerosol generating matrix in the storage chamber 10a flows through the liquid hole 14a to the storage element 16, and is then supplied to the atomizing core 13 via the storage element 16. The storage element 16 has a certain liquid-locking capacity, which helps to control the liquid supply rate of the storage chamber 10a to the atomizing core 13, thereby reducing the probability of leakage due to excessive liquid supply. At the same time, even if the surface of the atomizing core 13 used to absorb the aerosol generating matrix is ​​large, there will be no problem of excessive liquid supply. Therefore, no additional structure needs to be added to the surface of the atomizing core 13 used to absorb the aerosol generating matrix to limit the liquid supply rate, which simplifies the structure of the atomizing core 13.

[0055] The specific type of the liquid reservoir 16 is not limited. For example, it can be cotton. Preferably, the porosity of the liquid reservoir 16 is less than the porosity of the liquid guiding element of the atomizing core 13, such that the conduction velocity of the aerosol generating matrix in the liquid reservoir 16 is less than the conduction velocity in the liquid guiding element.

[0056] In this embodiment, the atomizer 10 has a liquid storage chamber 10a that stores the aerosol generating matrix in a liquid state. During liquid supply, the aerosol generating matrix is ​​guided along the height direction of the atomizer 10 through the liquid hole 14a to the liquid storage component 16, and then supplied radially to the atomizing core 13. The volume of the liquid storage component 16 does not need to be set to be equivalent to the volume of the liquid storage chamber 10a, which helps to reduce the amount of aerosol generating matrix remaining during the use of the atomizer 10. Moreover, the liquid storage component 16 can improve the leakage problem at the atomizing core 13. Therefore, the atomizing core 13 does not need to have any additional structures added to limit the liquid supply speed, which helps to simplify the structure of the atomizing core 13 and reduce the production cost of the atomizing core 13.

[0057] In some embodiments, please refer to the following: Figure 2 and Figure 4 The mounting slot 12m includes a first slot 12m1 and a second slot 12m2 that are connected and aligned along the axial direction of the atomizing core 13. The atomizing core 13 passes through the second slot 12m2 and is inserted into the first slot 12m1. The liquid storage component 16 is located in the second slot 12m2.

[0058] It is understandable that the diameter of the second tank 12m2 is larger than that of the first tank 12m1. That is, a stepped surface is formed on the side of the second tank 12m2 near the first tank 12m1, and the liquid storage component 16 can abut against the stepped surface.

[0059] In this embodiment, the liquid storage component 16 is accommodated by the second groove 12m2, which facilitates the installation of the liquid storage component 16. At the same time, a stepped surface can be formed on the groove wall of the installation groove 12m, which helps to further improve the installation stability and reliability of the liquid storage component 16.

[0060] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The atomizing seat 12 has an air exchange channel 12a and a first air inlet channel 12b. One end of the first air inlet channel 12b is connected to the outside atmosphere, and the other end is connected to the inner cavity 13a and the air exchange channel 12a. The other end of the air exchange channel 12a is connected to the liquid storage tank 10a.

[0061] In one specific embodiment, please refer to Figure 2 The other end of the first air intake channel 12b can be directly connected to the inner cavity 13a, and the other end of the air exchange channel 12a can be directly connected to the liquid passage 14a, that is, the other end of the air exchange channel 12a is connected to the liquid storage tank 10a through the liquid passage 14a.

[0062] As the aerosol generation matrix in the liquid storage chamber 10a is consumed, the negative pressure inside the liquid storage chamber 10a will increase, making it more and more difficult to dispense liquid. Replenishing the liquid storage chamber 10a with air through the ventilation channel 12a helps to maintain the air pressure inside the liquid storage chamber 10a, thereby enabling the liquid storage chamber 10a to continuously supply liquid to the atomizing core 13. This helps to improve the problem of burnt smell caused by insufficient aerosol generation matrix at the atomizing core 13.

[0063] The ventilation channel 12a is connected to the outside atmosphere through the first air intake channel 12b. In this way, the extension path of the ventilation channel 12a on the atomizer seat 12 can be set to be shorter, that is, it does not need to extend to the outer surface of the atomizer 10. This facilitates the opening of the ventilation channel 12a.

[0064] The specific structure of the ventilation channel 12a is not limited.

[0065] In some embodiments, the atomizing seat 12 has an internal ventilation channel 12a, that is, the cross-section of the ventilation channel 12a obtained by cutting the ventilation channel 12a with a plane perpendicular to the flow direction of the fluid in the ventilation channel 12a has a fully enclosed structure.

[0066] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 The ventilation channel 12a includes a groove 12a1 located on the surface of the atomizing seat 12.

[0067] Here, the cross-section obtained by cutting the ventilation channel 12a with a plane perpendicular to the flow direction of the fluid in the ventilation channel 12a has a semi-enclosed structure.

[0068] It is understandable that the groove 12a1 is formed on the surface of the atomizing seat 12, which makes the manufacturing process relatively simple and facilitates the formation of the air exchange channel 12a.

[0069] In one specific embodiment, please refer to Figure 4 and Figure 5 In an embodiment where the atomizing seat 12 has a mounting groove 12m, the groove 12a1 may be formed on the groove wall of the mounting groove 12m, and may be a capillary groove structure. This facilitates the connection between the air exchange channel 12a formed by the groove 12a1 and the first air intake channel 12b.

[0070] The specific dimensions of groove 12a are not limited.

[0071] In some embodiments, please refer to Figure 4 and Figure 5 The width of groove 12a1 ranges from 0.2mm to 0.5mm. This dimension is as follows... Figure 5As shown in D1. For example, it can be 0.2mm, 0.21mm, 0.23mm, 0.25mm, 0.27mm, 0.29mm, 0.3mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.4mm, 0.42mm, 0.44mm, 0.46mm, 0.48mm, 0.5mm, etc.

[0072] In some embodiments, please refer to Figure 4 and Figure 5 The depth of groove 12a1 ranges from 0.2mm to 0.5mm. This dimension is as follows... Figure 5 As shown in D2. For example, it can be 0.2mm, 0.21mm, 0.23mm, 0.25mm, 0.27mm, 0.29mm, 0.3mm, 0.32mm, 0.34mm, 0.36mm, 0.38mm, 0.4mm, 0.42mm, 0.44mm, 0.46mm, 0.48mm, 0.5mm, etc.

[0073] In this embodiment, the size of the groove 12a1 is more suitable. On the one hand, the groove 12a1 has a certain liquid-locking ability, which helps to reduce the probability of the aerosol generation matrix in the liquid storage chamber 10a leaking through the ventilation channel 12a. On the other hand, it helps to ensure the ventilation capacity of the ventilation channel 12a, thereby ensuring the air replenishment efficiency of the ventilation channel 12a, which helps to reduce the probability of burnt smell problems at the atomizing core 13.

[0074] In some embodiments, please refer to Figure 2 The atomizing seat 12 has an annular column 121, which surrounds and forms at least part of the first air intake channel 12b. The top surface of the annular column 121 is higher than the end of the air exchange channel 12a that is connected to the first air intake channel 12b along the axial direction of the atomizer 10.

[0075] That is, one end of the ventilation channel 12a is located below the inner cavity 13a and can be directly connected to the inner cavity 13a, and one end of the annular column 121 extends into the inner cavity 13a.

[0076] Here, the air inlet of the groove 12a1 is located at the bottom of the atomizing core 13, and a groove-shaped space is formed between the groove wall of the mounting groove 12m and the outer wall of the annular column 121. In this way, even if the aerosol generating matrix flows out through the ventilation channel 12a, it can remain in this groove-shaped space. Moreover, the air inlet of the ventilation channel 12a is liquid-sealed here, that is, gas can hardly enter the liquid storage chamber 10a. Therefore, the liquid storage chamber 10a will not continuously leak.

[0077] In some embodiments, please refer to Figure 2The atomizing seat 12 has a second air intake channel 12c, and the first air intake channel 12b is connected to the outside atmosphere through the second air intake channel 12c. The axial direction of the first air intake channel 12b and the axial direction of the second air intake channel 12c are set at an angle.

[0078] Specifically, the axial direction of the first air intake channel 12b can be parallel to the height direction of the atomizer 10, and the axial direction of the second air intake channel 12c can be perpendicular to the axial direction of the first air intake channel 12b.

[0079] In this embodiment, since the first air intake channel 12b and the second air intake channel 12c form an angle at their connection point, this angle helps to further reduce the probability of leakage of the atomizer 10.

[0080] In some embodiments, please refer to Figure 2 The first position is the connection point between the second air intake channel 12c and the first air intake channel 12b, and the second position is the end of the first air intake channel 12b furthest from the inner cavity 13a. The height of the first position is higher than the height of the second position. In this way, even if some aerosol generation matrix flows out through the first air intake channel 12b, it is more likely to flow into the bottom end of the first air intake channel 12b, making it difficult to enter the second air intake channel 12c. This helps to further reduce the probability of leakage of the atomizer 10.

[0081] In some embodiments, please refer to Figure 2 The first air intake channel 12b is formed into a closed structure at the end away from the inner cavity 13a and constitutes a sealing wall 122. The sealing wall 122 is provided with a wire hole 122a. The atomizer 10 also includes an electrical connector, which is sealed and passed through the wire hole 122a and electrically connected to the atomizing core 13.

[0082] The bottom end of the first air intake channel 12b is formed as a sealed wall 122, which helps to further reduce the probability of leakage of the atomizer 10.

[0083] Here, the liquid passage 14a penetrates the sealing wall 122 along the axial direction of the first air inlet channel 12b. The electrical connector is installed and sealed within the wire passage 122a.

[0084] It should be noted that there are no restrictions on the specific method by which the electrical connector is sealed and fixed within the wire hole 122a. For example, sealing and fixing can be achieved by applying adhesive.

[0085] Please see Figure 2 The atomizer 10 also includes a tip pin 15, an electrical connector is electrically connected to the tip pin 15, and after the power supply assembly is assembled with the atomizer 10, the power supply assembly is electrically connected to the tip pin 15.

[0086] In this embodiment, by providing a wire passage hole 122a and fixing the electrical connector within it, the atomizer 10 does not need to have a heating element for supporting the atomizing core 13 or a structure for fixing the electrical connector. This facilitates the installation of the annular column 121 on the atomizing base 12, thereby forming a groove-shaped space on the bottom side of the mounting groove 12m. This allows for the formation of a liquid seal at the air inlet of the groove 12a1 in case of leakage, thus reducing the probability of continuous leakage. Furthermore, the annular column 121 also provides support for the heating element 131.

[0087] In some embodiments, For example, please refer to Figure 2 The sealing element 14 and the atomizing seat 12 surround to form an air intake chamber 10b, which surrounds the outer periphery of the first air intake channel 12b. The second air intake channel 12c extends radially along the first air intake channel 12b and its two ends are respectively connected to the air intake chamber 10b and the first air intake channel 12b.

[0088] The air intake chamber 10b is formed by at least two components, which makes it easier for the components used to form the air intake chamber 10b to be demolded, thereby simplifying the production of the components of the atomizer 10.

[0089] In this embodiment, even if some of the aerosol generation matrix flows out through the second air inlet channel 12c, the aerosol generation matrix can be at least partially intercepted through the air inlet chamber 10b. This helps to further reduce the probability of leakage problems in the atomizer 10.

[0090] In some embodiments, please refer to Figure 2 The atomizing seat 12 has a third air intake channel 12d, and the air intake chamber 10b is connected to the outside atmosphere through the third air intake channel 12d. The connection port between the second air intake channel 12c and the air intake chamber 10b is the first connection port, and the connection port between the air intake chamber 10b and the third air intake channel 12d is the second connection port. On the axial section of the second air intake channel 12c, the first connection port and the second connection port are respectively located on both sides of the axis of the first air intake channel 12b.

[0091] The axial section of the second intake passage 12c refers to the section passing through the axis of the second intake passage 12c, and this section is parallel to or coplanar with the axis of the first intake passage.

[0092] In this way, after air enters the air intake chamber 10b through the second connecting port, it needs to rotate a certain angle around the wall forming the first air intake channel 12b before it can enter the second air intake channel 12c through the first connecting port. That is to say, even if some aerosol generating matrix flows into the air intake chamber 10b through the second air intake channel 12c, this part of the aerosol generating matrix still needs to flow around the first air intake channel 12b at a certain angle before it can seep out through the third air intake channel 12d. This helps to extend the flow path of the leak in the atomizer 10 and increases the difficulty of the leak flowing in the atomizer 10, thus further reducing the probability of leakage problems in the atomizer 10.

[0093] In some embodiments, please refer to Figure 2 The seal 14 also includes an integrally formed third part 143, which is located on the side of the air inlet chamber 10b away from the liquid storage chamber 10a, and the third part 143 is sealed between the atomizing seat 12 and the inner wall of the housing 11.

[0094] By setting the third part 143, the sealing performance of the gap between the atomizing seat 12 and the inner wall of the housing 11 is improved, which in turn improves the sealing performance of the air intake chamber 10b, thereby further reducing the risk of leakage.
