Description

Technical Field

[0001] This utility model relates to the field of atomization technology, specifically to an atomizer and an aerosol generating device. Background Technology

[0002] Aerosol generating devices are used to generate aerosols for users to inhale.

[0003] The aerosol generating device is equipped with an airflow channel, which is used to connect the main storage chamber of the aerosol generating device for storing the aerosol generating matrix and to connect directly or indirectly with the outside world, so as to maintain the pressure balance between the main storage chamber and the external air pressure of the aerosol generating device, and facilitate the flow of the aerosol generating matrix to contact the atomizing core used to convert the aerosol generating matrix into aerosol.

[0004] In related technologies, the main storage chamber is equipped with a porous liquid storage device that can absorb the aerosol generation matrix to reduce its fluidity, thereby controlling the rate at which the atomizing core absorbs and generates the aerosol generation matrix. A ventilation pipe is also provided in the main storage chamber, a portion of which can be inserted into the interior of the liquid storage device. The airflow channel communicates with the main storage chamber through the ventilation pipe.

[0005] During the assembly of the aerosol generating device, as the venting pipe is inserted into the liquid storage component, the venting pipe will compress a portion of the liquid storage component along the insertion direction, making the solid structure within that portion of the unit volume denser and reducing the space of pores, thereby increasing the resistance to gas flow within that portion of the liquid storage component. Utility Model Content

[0006] In view of this, the present invention aims to provide an atomizer and aerosol generating device that are beneficial to improving the airflow exchange efficiency between the airflow channel and the liquid storage component.

[0007] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0008] This utility model embodiment provides an atomizer, the atomizer comprising:

[0009] Atomizer coil;

[0010] The mounting components include an installation space, and the atomizing core is disposed within the installation space and together with the inner wall of the installation space forms a main storage cavity;

[0011] A liquid storage device is located within the main storage cavity, and the liquid storage device is provided with pores to store the aerosol generation matrix;

[0012] An air exchange pipe is at least partially disposed within the liquid storage component and extends along a first direction. An airflow channel is provided inside the air exchange pipe, and the airflow channel communicates with the outside of the atomizer. An opening communicating with the airflow channel is provided on the outer surface of the air exchange pipe. In a projection plane parallel to the first direction, at least a portion of the projection of the opening forms an angle α with the first direction, and 0°≤α<90°.

[0013] In some embodiments, at least a portion of the surface of the ventilation pipe along the first direction is an inclined plane, the inclined plane being a plane and forming an acute angle with the first direction, and the opening including a first sub-port, at least a portion of which is located on the inclined plane.

[0014] In some embodiments, the end face of the ventilation pipe along the first direction is the inclined surface, and the first sub-port is completely located within the inclined surface;

[0015] Alternatively, the surface of the ventilation pipe along the first direction may further include an end plane, the end plane extending perpendicularly to the first direction and connecting with the inclined surface, the inclined surface being located on the side of the end plane along the first direction near the connection position between the ventilation pipe and the inner wall of the installation space.

[0016] In some embodiments, the opening includes a second sub-port located on the sidewall of the ventilation pipe perpendicular to the first direction.

[0017] In some embodiments, the airflow channel includes a channel body and an air exchange slot, the channel body extending along a first direction, the air exchange slot extending along a second direction and communicating with the channel body, the first direction intersecting the second direction, and the air exchange slot opening on one side along the second direction to form at least a portion of the second sub-port.

[0018] In some embodiments, the area of ​​the contour formed by the second sub-port is not less than the minimum cross-sectional area of ​​the channel body perpendicular to the first direction;

[0019] And / or, the ventilation duct is open on one side along a third direction, which is perpendicular to the first direction and the second direction, respectively.

[0020] In some embodiments, the opening is located inside the liquid reservoir.

[0021] In some embodiments, the mounting assembly includes a housing and a sealing body. The housing has a mounting cavity that is open on one side along the first direction. The atomizing core is located in the mounting cavity. The sealing body is sealed over the open portion of the mounting cavity and is in a sealed fit with the atomizing core along the first direction. The atomizing core, the sealing body, and the housing together form the main storage cavity. At least one of a portion of the inner wall of the mounting cavity along the first direction and a portion of the surface of the sealing body on one side along the first direction forms the ventilation pipe.

[0022] In some embodiments, the sealing body is provided with a mounting hole extending through the first direction, the mounting hole connecting the outside of the atomizer and the main storage chamber, and the air exchange pipe passing through the mounting hole and sealingly fitting against the inner wall of the mounting hole.

The storage component has an additional storage chamber, the main storage chamber and the additional storage chamber are connected, and the airflow channel is connected to the outside of the aerosol generating device.

[0024] In the embodiments of this application, the atomizer, during the relative movement between the liquid storage component and the air exchange pipe along the first direction, helps to reduce or even eliminate the compression deformation caused by the solid structure of the air exchange pipe forming the opening on the liquid storage component, thereby reducing the tendency of the liquid storage component to become denser due to force, thus meeting the airflow flow requirements between the opening and the pores of the liquid storage component, which helps to make the airflow between the liquid storage component and the airflow channel more stable, and reduces the probability of negative pressure forming in the main storage cavity and affecting the flow of the aerosol generation matrix.

[0052] This application provides an atomizer 10 for use in an aerosol generating device. The atomizer 10 can convert an aerosol generating matrix into an aerosol for a user to inhale.

[0053] Specifically, see Figures 1 to 3 The atomizer 10 includes an atomizing core 11, a mounting assembly 12, and a liquid reservoir 13.

[0054] The mounting assembly 12 has an mounting space 12a, the atomizing core 11 is located in the mounting space 12a and together with the inner wall of the mounting space 12a forms the main storage cavity 12b, and the airflow channel 121d connects to the outside of the atomizer 10.

[0055] The liquid storage device 13 is located in the main storage cavity 12b, and the liquid storage device 13 is provided with pores to store the matrix generated by absorbing aerosols.

[0056] At least a portion of the air exchange pipe 121 is disposed within the liquid storage component 13 and extends along the first direction. An airflow channel 121d is provided inside the air exchange pipe 121, which connects to the outside of the atomizer 10. An opening 121a is provided on the outer surface of the air exchange pipe 121, which communicates with the airflow channel 121d. In a projection plane parallel to the first direction, at least a portion of the projection of the opening 121a forms an angle α with the first direction, and 0°≤α<90°.

[0057] After the atomizing core 11 comes into contact with the aerosol generating matrix, it can convert the aerosol generating matrix into aerosol through heating or other means. The aerosol is then discharged from the atomizer 10 for the user to inhale.

[0058] Installation space 12a is used to accommodate atomizing core 11 and aerosol generation matrix.

[0059] At least a portion of the atomizing core 11 is spaced apart from the inner wall of the mounting space 12a to form a main storage cavity 12b, which is used to contain the aerosol generation matrix.

[0060] It is understandable that the aerosol generation matrix is ​​a fluid medium that can flow within the main storage chamber 12b to contact the atomizing core 11.

[0061] Understandably, as the aerosol-generating matrix in the main storage chamber 12b is consumed, the air pressure in the main storage chamber 12b becomes negative relative to the air pressure in the atomizing chamber 11a, making it difficult for the aerosol-generating matrix in the main storage chamber 12b to flow to the atomizing core 11. Since the airflow channel 121d is connected to the outside of the atomizer 10, under the negative pressure state in the main storage chamber 12b, air from outside the atomizer 10 can enter the main storage chamber 12b through the airflow channel 121d, thereby restoring the air pressure in the main storage chamber 12b to a normal state and reducing the adverse effects on the flow of the aerosol-generating medium in the main storage chamber 12b.

[0062] The liquid reservoir 13 and the atomizing core 11 are in fluid communication, allowing fluid to flow from one to the other. The specific method of achieving fluid communication between the two is not limited; for example, they may be in direct contact, or a channel may be provided between them so that fluid can pass through the channel to make contact with both.

[0063] After the reservoir 13 comes into contact with the aerosol generating matrix, the aerosol generating matrix can be absorbed by the reservoir 13 and stored in the space within its pores through capillary action. At least some of the pores are interconnected, so that the aerosol generating matrix can flow inside the reservoir 13 and onto the atomizing core 11, which is in fluid communication with the reservoir 13. Thus, when the aerosol generating matrix in the atomizing core 11 is consumed to a certain extent, the reservoir 13 can replenish the aerosol generating matrix to the atomizing core 11. At the same time, due to the presence of pores, airflow can also pass through the reservoir 13 through the interconnected pores. In other words, the channels formed by the interconnected pores in the reservoir 13 allow both airflow and aerosol generating matrix to pass through.

[0064] Air from outside the atomizer 10 can enter the pores of the liquid storage component 13 through the airflow channel 121d and opening 121a. At the same time, the obstruction of the inner wall of the pores in the liquid storage component 13 makes it difficult for the aerosol generation matrix in the main liquid storage chamber to form a liquid flow that flows directly into the airflow channel 121d through the opening 121a, thus reducing the risk of leakage of the aerosol generation matrix through the airflow channel 121d.

[0065] During the assembly of the atomizer 10, the liquid reservoir 13 can move relative to the air exchange tube 121 in a first direction, such that at least a portion of the air exchange tube 121 is inserted into the liquid reservoir 13 in the first direction. During the relative movement of the two in the first direction, the air exchange tube 121 abuts against a portion of the liquid reservoir 13 in the first direction and applies a force in the first direction to the liquid reservoir 13.

[0066] It is understandable that because the liquid storage component 13 has pores, the structural strength of the liquid storage component 13 is low. Therefore, the vent pipe 121 can squeeze the liquid storage component 13 along the first direction, so that a part of the surface of the liquid storage component 13 near the vent pipe 121 along the first direction is compressed. As a result, the spatial proportion of pores in this part of the liquid storage component 13 is lower than that of other parts of the liquid storage component 13, and the solid structure forming the pores is more compact. Therefore, it is difficult for gas to flow in this part.

[0067] See Figure 6 and Figure 7 The projection of the solid structure forming the boundary of opening 121a onto a projection plane parallel to the first direction forms line segments. The angle between the extension direction of at least a portion of these line segments and the straight line extending along the first direction is α. 0°≤α<90° indicates that the extension direction of at least a portion of the solid structure forming the boundary of opening 121a is inclined to or parallel to the relative movement direction between the ventilation pipe 121 and the liquid storage component 13, i.e., the first direction. Therefore, it is beneficial to reduce or even eliminate the squeezing force between this portion of the solid structure and the liquid storage component 13 in contact with it.

[0068] In this embodiment, the atomizer 10, during the relative movement between the liquid storage component 13 and the air exchange pipe 121 along the first direction, helps to reduce or even eliminate the compression deformation caused by the solid structure of the air exchange pipe 121 forming the opening 121a on the liquid storage component 13. This reduces the tendency of the liquid storage component 13 to become denser due to stress, thereby meeting the airflow requirements between the opening 121a and the pores of the liquid storage component 13. This helps to make the airflow between the liquid storage component 13 and the airflow channel 121d more stable, reducing the probability of negative pressure forming in the main storage cavity 12b and affecting the flow of the aerosol generation matrix.

[0069] It is understood that, in a projection plane parallel to the first direction, the projected profile of the boundary of opening 121a can be a straight line segment or a circular arc segment. In an embodiment where the projected profile of the boundary of opening 121a is a straight line segment, see [reference needed]. Figure 4 The angle between the line containing the straight line segment and the line extending along the first direction is α; in an embodiment where the projected profile of the boundary of the opening 121a is an arc segment, the angle between the line containing at least a portion of the tangent of the arc segment and the line extending along the first direction is α.

[0070] It is understandable that one end of the airflow channel 121d can be directly connected to the outside of the atomizer 10; or one end of the airflow channel 121d can be connected to other channels inside the atomizer 10, which are directly connected to the outside of the atomizer 10.

[0071] In some embodiments, see Figure 2 The atomizing core 11 has an atomizing chamber 11a, which is connected to the outside of the atomizer 10. The atomizing chamber 11a is isolated from the main storage chamber 12b, so that the aerosol generating matrix in the main storage chamber 12b is difficult to enter the atomizing chamber 11a without being converted into aerosol, thereby reducing the risk of the aerosol generating matrix leaking from the atomizer 10.

[0072] It is understandable that the pores of the liquid storage component 13 can be macroscopically visible to the naked eye or microscopically invisible to the naked eye, as long as they meet the requirements of absorbing aerosols through capillary action to generate a matrix and allowing airflow to pass through.

[0073] The specific form of the liquid storage component 13 is not limited, such as cotton wool, sponge, or fiber structure woven or twisted from chemical fibers such as polyester and nylon.

[0074] In some embodiments, see Figure 4 and Figure 5 The liquid storage component 13 covers at least a portion of the circumference of the air exchange pipe 121 perpendicular to the first direction. This facilitates the stop fit between the liquid storage component 13 and the air exchange pipe 121 in any direction perpendicular to the first direction, and helps to maintain the stability of the position of the opening 121a and the liquid storage component 13 during the use of the atomizer 10.

[0075] In some embodiments, see Figure 4 and Figure 6 At least a portion of the surface of the ventilation pipe 121 along the first direction is an inclined plane 121b, the inclined plane 121b is a plane and the angle between it and the first direction is an acute angle, the opening 121a includes a first sub-opening 121aa, at least a portion of the first sub-opening 121aa is located on the inclined plane 121b.

[0076] The inclined plane 121b is a plane, which helps to simplify the production process of forming the surface of the ventilation pipe 121 along the first direction.

[0077] The angle between the inclined plane 121b and the first direction is an acute angle, that is, the angle between the normal of the inclined plane 121b and the straight line containing the first direction is an acute angle. Therefore, the force of the contact between the vent pipe 121 and the liquid storage device 13 can be divided into a component force along the first direction and a component force perpendicular to the first direction.

[0078] During the movement of the venting pipe 121 relative to the liquid storage unit 13 along the first direction, it is beneficial to increase the contact area between the portion of the venting pipe 121 forming the first sub-orifice 121aa and the liquid storage unit 13, and only a portion of the force exerted by the venting pipe 121 on the liquid storage unit 13 can compress the liquid storage unit 13. Therefore, when the inclined surface 121b and the liquid storage unit 13 move relative to each other along the first direction and come into contact, the force exerted on the liquid storage unit 13 can be reduced, thereby reducing the tendency for the portion of the liquid storage unit 13 in contact with the inclined surface 121b to become denser, which is beneficial to meeting the airflow requirements between the first sub-orifice 121aa on the inclined surface 121b and the pores of the liquid storage unit 13.

[0079] It is understandable that, on the projection plane parallel to the first direction, the angle α between the projection of the contour of the first sub-mouth 121aa located on the inclined plane 121b and the straight line along the first direction satisfies 0° < α < 90°.

[0080] In some embodiments, see Figure 6 The end face of the ventilation pipe 121 along the first direction is an inclined surface 121b, and the first sub-port 121aa is completely located within the inclined surface 121b.

[0081] The end face of the ventilation pipe 121 along the first direction refers to the surface of the end of the ventilation pipe 121 along the first direction away from the connection position between the ventilation pipe 121 and the installation space 12a.

[0082] The end face is a bevel 121b, which means that the end face is a complete plane. This is beneficial to increase the size of the bevel 121b and further reduce the pressure applied to the liquid storage component 13 when the bevel 121b moves relative to and abuts against the liquid storage component 13 in the first direction. It is also beneficial to form the bevel 121b in one step during the manufacturing process by cutting, grinding and other methods, which reduces the dimensional matching requirements during the manufacturing process of the bevel 121b and simplifies the manufacturing process.

[0083] The first sub-port 121aa is completely located within the inclined plane 121b, which helps to increase the number of pores connected to the first sub-port 121aa and improve the airflow efficiency.

[0084] In some embodiments, see Figure 4 The ventilation pipe 121 also includes an end plane 121c on one side of the first direction. The end plane 121c extends perpendicularly to the first direction and is connected to the inclined surface 121b. The inclined surface 121b is located on the side of the end plane 121c along the first direction near the connection position between the ventilation pipe 121 and the inner wall of the installation space 12a.

[0085] During the movement of the ventilation pipe 121 relative to the liquid storage component 13 in the first direction, the end plane 121c contacts and compresses the liquid storage component 13 before the inclined surface 121b, which helps to reduce the compression of the portion of the liquid storage component 13 opposite to the inclined surface 121b in the first direction, and helps to meet the airflow requirements between the first sub-port 121aa on the inclined surface 121b and the pores of the liquid storage component 13.

[0086] In some embodiments, at least a portion of the surface of the ventilation pipe 121 along the first direction is an arc surface, and at least a portion of the first sub-port 121aa is located on the arc surface.

[0087] This increases the contact area between the portion of the ventilation pipe 121 surrounding the first sub-port 121aa and the liquid storage component 13 along the first direction. Furthermore, only a portion of the force exerted by the ventilation pipe 121 on the liquid storage component 13 can be transmitted to the liquid storage component 13 along the first direction, thereby reducing the pressure applied to the liquid storage component 13. This helps to reduce the tendency of the portion of the liquid storage component 13 in contact with the arc surface to become denser, which is beneficial to meeting the airflow requirements between the first sub-port 121aa on the inclined surface 121b and the pores of the liquid storage component 13.

[0088] It is understandable that the arc surface can be either convex or concave along the first direction.

[0089] It is understood that the liquid storage component 13 may be pre-formed with an insertion hole extending along the first direction, with one side of the insertion hole open along the first direction so that the vent pipe 121 can be inserted into the insertion hole through the open position of the insertion hole along the first direction, and the vent pipe 121 can abut against the bottom wall of the insertion hole along the first direction; or, the vent pipe 121 may be directly inserted into the liquid storage component 13 along the first direction, and a portion of the liquid storage component 13 may be squeezed along the first direction so that at least a portion of the vent pipe 121 is embedded in the liquid storage component 13.

[0090] The specific number of the first sub-mouth 121aa is not limited; it can be one or more.

[0091] In some embodiments, see Figure 5 and Figure 7 The opening 121a includes a second sub-opening 121ab, which is located on the side wall of the ventilation pipe 121 perpendicular to the first direction.

[0092] During the movement of the venting pipe 121 relative to the liquid storage component 13 in the first direction, the portion of the venting pipe 121 surrounding the second sub-port 121ab will not interact with the liquid storage component 13 in the first direction. Therefore, the spatial proportion of the internal pores of the liquid storage component 13 located near the second sub-port 121ab is less affected by the interaction force between the venting pipe 121 and the liquid storage component 13, which is beneficial to meeting the airflow requirements between the second sub-port 121ab and the pores of the liquid storage component 13.

[0093] Understandably, see Figure 5 On a projection plane parallel to the first direction, the angle α between the projection of the partial outline of the second sub-mouth 121ab and the straight line along the first direction is 0°.

[0094] The specific method of forming the second sub-mouth 121ab is not limited.

[0095] For example, see Figure 5 and Figure 7 The airflow channel 121d includes a channel body and an air exchange groove 121db. The channel body extends along a first direction, and the air exchange groove 121db extends along a second direction and communicates with the channel body. The first direction intersects with the second direction. The air exchange groove 121db is open on one side along the second direction to form at least a portion of the second sub-port 121ab.

[0096] In this way, an airflow path is formed in which the pores of the channel body, the air exchange groove 121db, and the liquid storage component 13 are interconnected. The channel body is connected to the outside of the atomizer 10, so that external gas can enter the pores of the liquid storage component 13 in sequence through the channel body and the air exchange groove 121db.

[0097] In some embodiments, the first direction is perpendicular to the second direction.

[0098] In some embodiments, see Figure 8 The ventilation slot 121db passes through the ventilation pipe 121 along the second direction.

[0099] In this way, on the one hand, it is beneficial to increase the number of second sub-ports 121ab and the total area of ​​the contour formed by the second sub-ports 121ab, thereby reducing the risk of airflow obstruction caused by blockage of the second sub-ports 121ab; on the other hand, in the process of manufacturing the ventilation groove 121db, there is no need to consider the depth dimension of the ventilation groove 121db along the second direction, which is beneficial to reduce manufacturing difficulty and improve manufacturing efficiency.

[0100] In some embodiments, the area of ​​the contour formed by the second sub-port 121ab is not less than the minimum cross-sectional area of ​​the channel body perpendicular to the first direction.

[0101] The outline formed by the second sub-port 121ab refers to the shape formed by the structure of the ventilation pipe 121 covering the second sub-port 121ab along its original extension direction. The surface area of ​​this shape is the area of ​​the outline formed by the second sub-port 121ab.

[0102] This ensures that the airflow through the second sub-port 121ab meets the airflow requirements inside the main channel, which helps reduce the probability of a negative pressure state occurring inside the main storage chamber 12b.

[0103] In some embodiments, see Figure 8 The ventilation duct 121db is open on one side along the third direction, which is perpendicular to the first direction and the second direction respectively.

[0104] This is beneficial to the total area of ​​the contour formed by the second sub-port 121ab, reducing the risk of airflow obstruction caused by the second sub-port 121ab being blocked.

[0105] During the manufacturing of the ventilation pipe 121, a portion of the blank forming the ventilation pipe 121 can be cut along the second direction and then the portion can be peeled off along the third direction to form the ventilation groove 121db.

[0106] In some embodiments where the ventilation slot 121db extends through the ventilation pipe 121 in the second direction, see [reference]. Figure 8 The ventilation duct 121db opens along one side in the third direction.

[0107] In this way, the ventilation groove 121db can be formed by burning, cutting or other methods along the second direction, which reduces the manufacturing difficulty of the ventilation groove 121db and improves the manufacturing efficiency.

[0108] In some embodiments, see Figure 9 and Figure 10 The ventilation slot 121db is open on one side along the first direction, and part of the inner wall of the ventilation slot 121db forms the end face of the ventilation pipe 121 away from the connection position between the ventilation pipe 121 and the inner wall of the installation space 12a along the first direction.

[0109] Thus, a portion of the liquid storage component 13 can enter the ventilation groove 121db along the first direction, thereby reducing the compression of that portion of the liquid storage component 13 along the first direction, so that the airflow can flow between that portion of the liquid storage component 13 and the ventilation groove 121db.

[0110] In some embodiments, see Figure 10 The channel body 121da is open on one side along the first direction to communicate with the open position of the ventilation slot 121db along the first direction. This simplifies the manufacturing difficulty of the channel body 121da.

[0111] In some embodiments, the opening 121a is located outside the reservoir 13.

[0112] In other words, the air exchange tube 121 passes through the liquid storage component 13 in the first direction. That is to say, the air exchange tube 121 will only squeeze the liquid storage component 13 in the first direction when it moves relative to the liquid storage component 13 in the first direction during the assembly of the atomizer 10. However, during the user's daily use of the atomizer 10, the air exchange tube 121 will not squeeze the liquid storage component 13 in the first direction.

[0113] In other embodiments, see Figure 4 and Figure 5 The opening 121a is located inside the liquid storage component 13.

[0114] This allows for a stop-and-go fit between the air exchange tube 121 and the liquid storage unit 13, reducing the probability that the air exchange tube 121 will move relative to the storage unit 20 and cause the opening 121a to detach from the liquid storage unit 13 during the use of the atomizer 10. Furthermore, the gas and aerosol generation matrix must pass through the liquid storage unit 13 to enter and exit the opening 121a, which helps to reduce the probability of the aerosol generation matrix flowing into the airflow channel 121d by utilizing the porous structure formed in the liquid storage unit 13 during gas flow.

[0115] During daily use, due to factors such as vibration of the atomizer 10, the liquid storage component 13 may move relative to the air exchange tube 121, posing a risk that the air exchange tube 121 may puncture or detach from the liquid storage component 13.

[0116] In some embodiments where the opening 121a is located inside the liquid reservoir 13, see [reference]. Figure 5 The distance between the edge of the opening 121a and the outer surface of the liquid reservoir 13 along the first direction ranges from 3 mm to 10 mm. That is, 3 mm ≤ L1 ≤ 10 mm.

[0117] This increases the travel distance of the opening 121a from the liquid storage component 13 along the first direction, which helps to reduce the probability that the liquid storage component 13 can move relative to the ventilation pipe 121 and cause the opening 121a to be exposed. It also helps to reduce the risk that the liquid storage component 13 can move relative to the ventilation pipe 121 and cause the opening 121a to detach from the liquid storage component 13, thereby reducing the risk that the aerosol generation matrix will directly flow into the airflow channel 121d.

[0118] The specific distance between the edge of the opening 121a and the outer surface of the liquid storage component 13 along the first direction can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc.

[0119] The specific structural form of mounting component 12 is not limited.

[0120] In some embodiments, see Figure 3 The mounting assembly 12 includes a housing 122 and a sealing body 123. The housing 122 has a mounting cavity 122a, which is open on one side along a first direction. The atomizing core 11 is located in the mounting cavity 122a. The sealing body 123 is sealed and covers the open part of the mounting cavity 122a and is sealed and fitted with the atomizing core 11 along the first direction. The atomizing core 11, the sealing body 123 and the housing 122 together form a main storage cavity 12b. At least one of the inner wall of the mounting cavity 122a along the first direction and the surface of the sealing body 123 along the first direction is provided with a ventilation pipe 121.

[0121] During the assembly and installation of component 12, the air exchange pipe 121 is inserted into the liquid storage component 13 along the first direction, and then the sealing body 123 is placed over the opening of the installation cavity 122a along the first direction, so that the space between the sealing body 123 and the inner wall of the installation cavity 122a forms the installation space 12a, and the space formed between the atomizing core 11, the sealing body 123 and the shell 122 forms the main storage cavity 12b, and the liquid storage component 13 is located in the main storage cavity 12b.

[0122] Thus, the direction in which the vent pipe 121 is inserted into the liquid storage component 13 is the same as the direction in which the sealing body 123 covers the mounting cavity 122a, which helps to improve assembly efficiency.

[0123] It is understood that the ventilation pipe 121 may be provided only on the inner wall of the mounting cavity 122a, or only on the surface of the sealing body 123; or the ventilation pipe 121 may be provided on both the inner wall of the mounting cavity 122a and the sealing body 123.

[0124] The sealing body 123 is made of an elastic material to achieve a sealing effect on the main storage cavity 12b.

[0125] The specific structural form of the ventilation pipe 121 is not limited.

[0126] In some embodiments, see Figure 3 The sealing body 123 is provided with a mounting hole 123a that extends through in the first direction. The mounting hole 123a connects the outside of the mounting assembly 12 and the main storage cavity 12b. A part of the ventilation pipe 121 passes through the mounting hole 123a and is sealed and fitted to the inner wall of the mounting hole 123a.

[0127] The air exchange pipe 121 is sealed to the inner wall of the mounting hole 123a, which can reduce the probability that the aerosol generation matrix in the main storage chamber 12b will leak from the mounting hole 123a into the outside of the atomizer 10.

[0128] In some embodiments, the area of ​​the cross-section of the channel body 121da perpendicular to the first direction is 0.02 mm². 2 (Squaremillimeter, square millimeter) to 0.8 mm 2 .

[0129] Within this size range, the capillary action between the surface tension and air pressure of the aerosol generating matrix entering the airflow channel 121d can be utilized to form a liquid film in the aerosol generating matrix within the airflow channel 121d, thereby reducing the probability of the aerosol generating matrix flowing out of the airflow channel 121d.

[0130] The diameter of the cross-section of the channel body 121da perpendicular to its extension direction can be 0.02 mm. 2 0.03mm 2 0.05mm 2 0.08mm 2 0.1mm 2 0.2mm 2 0.3mm 2 0.4mm 2 0.5mm 2 0.6mm 2 .

[0131] The cross-sectional shape of the ventilation pipe 121 perpendicular to the first direction is not limited; for example, see [reference needed]. Figure 8 The cross-section is annular, which helps to reduce the deformation of the ventilation pipe 121 under external force; see reference. Figure 11 The cross-section is an elliptical ring. (See reference) Figure 12 The cross-section is a triangular ring, see reference. Figure 13 and Figure 14 The cross-section is a polygonal annular shape, which helps to suppress the tendency of the ventilation pipe 121 to rotate relative to the mounting hole 123a.

[0132] The specific material of the ventilation pipe 121 is not limited, such as stainless steel, engineering plastics, etc.

[0133] The specific material of the seal is not limited, such as silicone rubber, fluororubber, etc.

[0134] The specific method of forming the bevel 121b on the ventilation pipe 121 is not limited. For example, the pipe is cut at a certain angle with the first direction by grinding to form the bevel 121b on the cut surface.

[0135] The specific method of forming the ventilation groove 121db on the ventilation pipe 121 is not limited. For example, a portion of the pipe material can be removed by laser cutting to form the ventilation groove 121db.

[0136] This application also provides an aerosol production apparatus, see below. Figure 15 and Figure 17 The aerosol generating device includes a storage unit 20 and any of the atomizers 10 in the aforementioned embodiments. The storage unit 20 is provided with an additional storage chamber 20a. The main storage chamber 12b and the additional storage chamber 20a are connected. The airflow channel 121d is connected to the outside of the aerosol generating device.

[0137] After the airflow enters the main storage chamber 12b through the airflow channel 121d, it then enters the auxiliary storage chamber 20a, so that the aerosol generating device in the auxiliary storage chamber 20a can enter the main storage chamber 12b, thereby replenishing the loss of the aerosol generating matrix in the main storage chamber 12b.

[0138] Thus, opening 121a also helps to improve the efficiency of aerosol generation matrix in the auxiliary storage chamber 20a being replenished into the main storage chamber 12b.

[0139] In some embodiments, the storage unit 20 is detachably connected to the atomizer 10.
