This improves the efficiency of the atomizer in expelling aerosols, which is beneficial to enhancing the user experience. It also helps to reduce the number of atomizer components and improve the assembly efficiency of the atomizer. Attached Figure Description

[0074] In the description of the embodiments of this application, for ease of explanation, as shown in the accompanying drawings, the direction of arrow X is the straight line direction of the "first direction"; and the direction of arrow Y is the straight line direction of the "second direction".

[0075] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0076] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical term "contact" should be interpreted broadly, and can be direct contact, contact through an intermediate medium layer, contact between two contacting parties with substantially no interaction force, or contact between two contacting parties with interaction force.

[0077] This application provides an atomizer 10. Referring to Figures 1 to 4, the atomizer 10 includes an atomizing component 11, a housing 12, and a mounting base 13.

[0078] Mounting base 13 includes an airflow channel 13a, both ends of which are connected to the outside of mounting base 13. The inner wall of airflow channel 13a is provided with mounting hole 13b, which connects airflow channel 13a and the outside of mounting base 13. Atomizing component 11 blocks mounting hole 13b. Housing 12 and mounting base 13 together form liquid storage chamber 12a. Atomizing component 11 is in fluid communication with liquid storage chamber 12a. Mounting base 13 is an integral structure.

[0079] Airflow can enter from one end of airflow channel 13a and exit from the other end.

[0080] The storage chamber 12a is used to store the aerosol generation matrix. The aerosol generation matrix is ​​a fluid medium that can flow within the storage chamber 12a.

[0081] The atomizing component 11 is used to atomize the aerosol generation matrix by means of heating or other methods.

[0082] The atomizing component 11 is fluidly connected to the liquid storage chamber 12a, so that the aerosol generation matrix in the liquid storage chamber 12a can come into contact with the atomizing component 11.

[0083] The atomizing component 11 seals the mounting hole 13b, which on the one hand makes it difficult for the aerosol generation matrix in the liquid storage chamber 12a to directly enter the airflow channel 13a; on the other hand, the aerosol generated by the atomizing component 11 can directly diffuse into the airflow channel 13a.

[0084] The mounting base 13 is a one-piece structure, meaning that the mounting base 13 is a separate part, rather than an assembly formed by splicing multiple parts.

[0085] Referring to Figure 5, the small particle size segment refers to aerosols with a diameter ranging from 0.8 μm to 2 μm; the medium particle size segment refers to aerosols with a diameter ranging from 2.5 μm to 8 μm; and the large particle size segment refers to aerosols with a diameter ranging from 10 μm to 50 μm. The comparative example is a technical solution formed by splicing multiple components into the mounting base 13. The carry-out efficiency refers to the percentage of aerosols in the corresponding particle size range that leave the airflow channel 13a. The flue gas conversion efficiency is the overall efficiency of the aerosols from the small, medium, and large particle size segments that are carried out of the airflow channel 13a. As shown in Figure 5, the integrated structure of the mounting base 13 in this embodiment significantly improves the flue gas conversion efficiency compared to the comparative example.

[0086] Referring to Figure 6, the comparative example shows the airflow velocity in different regions within the mounting base 13 in a technical solution formed by splicing multiple components. Referring to Figure 7, the embodiment of this application shows the airflow velocity in different regions within the mounting base 13 in a technical solution using an integrated structure. Comparing Figures 6 and 7, it can be seen that, compared to the comparative example, the embodiment of this application shows a significantly lower airflow velocity and smaller differences in velocity between different regions, resulting in smoother airflow.

[0087] In this embodiment, the atomizer 10 is independently enclosed by the mounting base 13 to form an airflow channel 13a. This reduces the gaps on the inner wall of the airflow channel 13a, thereby reducing the probability that aerosols entering the airflow channel 13a will diffuse to other areas of the atomizer 10 through the gaps in the airflow channel 13a. This improves the efficiency of aerosol discharge from the atomizer 10, which is beneficial to enhancing the user experience. It also helps to reduce the number of parts in the atomizer 10 and improve the assembly efficiency of the atomizer 10.

[0088] The specific way in which the mounting base 13 forms an integral structure is not limited. For example, the mounting base 13 can be a single non-removable component formed by bonding multiple sub-components together; or the mounting base 13 can be a single component manufactured in one go by injection molding, additive manufacturing or other methods.

[0089] This application also provides an aerosol generating device, which includes the atomizer 10 in the aforementioned embodiments. Thus, by adopting an integrated structure for the mounting base 13, the overall airtightness of the aerosol generating device is improved, the probability of aerosol diffusion within the aerosol generating device is reduced, and the service life of the aerosol generating device is extended.

[0090] The specific structural form of the airflow channel 13a is not limited.

[0091] In some embodiments, referring to Figures 4 and 11, the airflow channel 13a includes a mounting cavity 13aa, a transition channel 13ab, and an air inlet channel 13ac. The mounting hole 13b is disposed in the mounting cavity 13aa. The transition channel 13ab connects the mounting cavity 13aa and the air inlet channel 13ac and is located upstream of the mounting cavity 13aa along the airflow direction. Both the air inlet channel 13ac and the mounting cavity 13aa can be connected to the outside of the atomizer 10. Both the mounting cavity 13aa and the air inlet channel 13ac extend along a first direction. In a direction perpendicular to the first direction, the mounting cavity 13aa and the air inlet channel 13ac are staggered.

[0092] In other words, the airflow flows sequentially along the intake channel 13ac, the transition channel 13ab, and the mounting cavity 13aa.

[0093] Understandably, the extension direction of the transition channel 13ab is different from that of the mounting cavity 13aa and the intake channel 13ac.

[0094] The mounting cavity 13aa and the intake channel 13ac are staggered, meaning that the line connecting the center of the cross section of the mounting cavity 13aa and the line connecting the center of the cross section of the intake channel 13ac are not on the same straight line and are parallel.

[0095] This allows the arrangement of the mounting cavity 13aa and the air intake channel 13ac to adapt to the shape and arrangement requirements of other components within the atomizer 10, making the structure of the atomizer 10 more compact.

[0096] In some embodiments, in a projection plane perpendicular to the first direction, at least a portion of the projection of the mounting cavity 13aa is located outside the projection range of the air intake channel 13ac, in order to accommodate the shape and arrangement requirements of other components within the atomizer 10.

[0097] In some embodiments, referring to FIG4, in a projection plane perpendicular to the first direction, the projection of the mounting cavity 13aa is completely outside the projection range of the air intake channel 13ac, so as to better accommodate the shape and arrangement requirements of other components within the atomizer 10.

[0098] In some embodiments, one end of the air intake channel 13ac is opened to form the air intake port 13d of the airflow channel 13a, so that the airflow outside the atomizer 10 enters the airflow channel 13a through the opening of the air intake channel 13ac.

[0099] It is understood that the connection between the mounting cavity 13aa and the transition channel 13ab is located on one side of the inner wall of the transition channel 13ab along the first direction, and the connection between the intake channel 13ac and the transition channel 13ab is located on the other side.

[0100] In some embodiments, referring to FIG4, the transition channel 13ab extends along a second direction, intersecting the first direction and the second direction, and the transition channel 13ab is open on one side along the second direction to communicate with the outside of the mounting base 13.

[0101] In this way, the transition channel 13ab can be formed during the manufacturing process of the mounting base 13 by means of excavation, drafting or other methods along the second direction, which facilitates the formation of the transition channel 13ab.

[0102] In some embodiments, the first direction is substantially perpendicular to the second direction.

[0103] In some embodiments, referring to FIG4, the end of the transition channel 13ab away from its open position is connected to either the mounting cavity 13aa or the air intake channel 13ac, thereby helping to reduce the size of the transition channel 13ab and reduce manufacturing difficulty.

[0104] In some embodiments, referring to FIG4, along the second direction, the cross-sectional area of ​​the transition channel 13ab gradually decreases in the direction away from its open position, and the end of the transition channel 13ab away from its open position is connected to the mounting cavity 13aa.

[0105] In this way, on the one hand, it is convenient for the mounting base 13 to form the transfer channel 13ab during the manufacturing process; on the other hand, it is convenient for the airflow in the transfer channel 13ab to enter the mounting cavity 13aa.

[0106] In some embodiments, referring to Figures 3 and 4, the atomizer 10 further includes a sealing sleeve 14, at least a portion of which is sealed over the open position of the transition channel 13ab, thereby reducing the risk of leakage caused by the opening formed by the open position of the airflow transition channel 13ab within the airflow channel 13a.

[0107] In some embodiments, referring to FIG4, along the first direction, the dimension between the connection position of the transition channel 13ab and the intake channel 13ac and the inner wall of the opposite transition channel 13ab is greater than 2.5 mm. That is, along the first direction, the dimension between the connection position of the transition channel 13ab and the intake channel 13ac and the inner wall of the opposite transition channel 13ab is L1, where L1 > 2.5 mm (millimeters).

[0108] Thus, after the airflow flows out of the intake channel 13ac and into the transition channel 13ab, the process of the airflow changing from flowing in the first direction to flowing in the second direction is conducive to a smoother and more gentle airflow turning process, reducing the probability of airflow generating turbulence, reducing the resistance encountered by the airflow, reducing the probability of the airflow hitting the inner wall of the transition channel 13ab in the first direction and rebounding, thereby hindering the entry of subsequent airflow, and helping to reduce the noise generated by the airflow flowing in the transition channel 13ab.

[0109] Along the first direction, the specific value of the dimension between the connection position of the transition channel 13ab and the intake channel 13ac and the inner wall of the corresponding transition channel 13ab can be 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc.

[0110] In some embodiments, referring to FIG4, along the first direction, the dimension between the communication position of the transition channel 13ab and the mounting cavity 13aa and the inner wall of the opposite transition channel 13ab is greater than 2mm. That is, along the first direction, the dimension between the communication position of the transition channel 13ab and the mounting cavity 13aa and the inner wall of the opposite transition channel 13ab is L7, where L7 > 2mm.

[0111] This makes the airflow smoother as it turns from the transition channel 13ab into the mounting cavity 13aa, which helps reduce the probability of airflow generating eddies.

[0112] Understandably, since the mounting base 13 is a one-piece structure, there are no gaps in the inner wall corresponding to the position where the airflow turns from the transition channel 13ab to enter the mounting cavity 13aa, which helps to make the airflow smoother.

[0113] In some embodiments, referring to FIG4, a buffer groove 13c is provided on one inner wall of the transition channel 13ab along the first direction. The buffer groove 13c is open on one side along the first direction and faces the communication position between the transition channel 13ab and the intake channel 13ac.

[0114] The inner wall of the transition channel 13ab is recessed on the side opposite to the connection position of the transition channel 13ab and the intake channel 13ac along the first direction to form a buffer groove 13c.

[0115] After the airflow enters the transfer channel 13ab, it can enter the buffer groove 13c through the open position of the buffer groove 13c. Under the constraint of the inner wall of the buffer groove 13c, it diffuses in all directions of the buffer groove 13c perpendicular to the first direction.

[0116] Thus, the constraint effect of the inner wall of the buffer groove 13c reduces the probability of airflow forming turbulence in the transfer channel 13ab, which is conducive to the airflow flowing more smoothly to the mounting cavity 13aa.

[0117] In some embodiments, in a projection plane perpendicular to the first direction, the projection of the connection position between the transition channel 13ab and the intake channel 13ac is located within the projection range of the open position of the buffer groove 13c.

[0118] This allows more airflow from the intake channel 13ac to enter the buffer groove 13c, where its flow direction is constrained by the inner wall of the buffer groove 13c, thereby further reducing the probability of turbulence forming in the transition channel 13ab.

[0119] In some embodiments where the transition channel 13ab is open on one side along the second direction, referring to FIG4, the buffer groove 13c is open on the side along the second direction near the open position of the transition channel 13ab, thereby facilitating the manufacture of the buffer groove 13c.

[0120] In some embodiments, referring to Figure 4, the inner wall of the buffer groove 13c near the connection position between the transition channel 13ab and the mounting cavity 13aa is an arc surface 13ca.

[0121] It is understood that at least part of the airflow flows within the buffer groove 13c until the inner wall of the buffer groove 13c near the connection position between the transition channel 13ab and the mounting cavity 13aa comes into contact with the inner wall of the buffer groove 13c. Under the constraint of this part of the inner wall, the airflow turns and flows out of the buffer groove 13c and toward the mounting cavity 13aa.

[0122] Thus, this part of the inner wall is a circular arc surface 13ca, which helps to guide the airflow to turn more gently and smoothly, thereby reducing the probability of turbulence generated during the turning process.

[0123] In some embodiments, the inner circumferential walls of the buffer groove 13c perpendicular to the first direction are all arc surfaces 13ca. This is beneficial to ensure that all airflows exiting the buffer groove 13c can achieve a smoother and more gentle turn under the constraint of the inner wall of the buffer groove 13c, reducing the probability of turbulence and making the airflow in the transition channel 13ab smoother.

[0124] In some embodiments, referring to FIG4, the edge of the open position of the buffer groove 13c near the communication position between the transition channel 13ab and the mounting cavity 13aa is rounded.

[0125] In other words, the side of the structure forming the opening of the buffer groove 13c near the connection position between the transition channel 13ab and the mounting cavity 13aa is rounded.

[0126] This makes the process of guiding the airflow out of the buffer trough 13c smoother and more gentle, thereby reducing the chance of turbulence during the outflow process.

[0127] In some embodiments, referring to Figure 4, the minimum distance between the connection position of the transition channel 13ab and the intake channel 13ac and the top wall of the buffer groove 13c along the first direction is greater than 2mm. That is, the minimum distance between the connection position of the transition channel 13ab and the intake channel 13ac and the top wall of the buffer groove 13c along the first direction is L2, where L2 > 2mm.

[0128] This helps to reduce the probability of airflow generating turbulence, reduce the resistance to airflow, and reduce the probability that airflow will bounce off the inner wall of the buffer groove 13c in the first direction and thus hinder the entry of subsequent airflow.

[0129] The specific dimensions of the minimum distance between the connection position of the transition channel 13ab and the intake channel 13ac and the top wall of the buffer groove 13c along the first direction can be 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 3mm, 3.5mm, etc.

[0130] In some embodiments, referring to FIG8, the airflow channel 13a includes a mounting cavity 13aa and an air inlet channel 13ac. A mounting hole 13b is provided in the mounting cavity 13aa. The air inlet channel 13ac communicates with the mounting cavity 13aa and is located upstream of the mounting cavity 13aa along the airflow direction. Both the air inlet channel 13ac and the mounting cavity 13aa can communicate with the outside of the atomizer 10 respectively. The mounting cavity 13aa and the air inlet channel 13ac both extend along a first direction and are aligned.

[0131] In other words, the mounting cavity 13aa is directly connected to the air intake channel 13ac.

[0132] Alignment of the mounting cavity 13aa and the intake passage 13ac means that the line connecting the centers of the cross sections of the mounting cavity 13aa and the line connecting the centers of the cross sections of the intake passage 13ac are on the same straight line.

[0133] In this way, after the airflow enters the intake channel 13ac, it can flow continuously in the first direction into the mounting cavity 13aa, which helps to reduce the probability of the airflow changing direction during the flow process, reduce the probability of turbulence generated during the airflow process, and make the airflow flow more smoothly.

[0134] In some embodiments, referring to Figures 4 and 11, the mounting hole 13b is located on the side of the mounting cavity 13aa perpendicular to the first direction, that is, the atomizing component 11 is located on the side of the mounting cavity 13aa perpendicular to the first direction.

[0135] In some embodiments, the atomizing component 11 has an atomizing surface 11a that is in fluid communication with the mounting cavity 13aa.

[0136] The atomizing surface 11a refers to the portion of the outer surface of the atomizing component 11 that can atomize aerosol to generate a matrix.

[0137] In this way, the aerosol generation matrix generated by the atomizing surface 11a can directly enter the mounting cavity 13aa, thereby mixing with the airflow entering the mounting cavity 13aa to form an aerosol.

[0138] In some embodiments, referring to FIG4, the plane containing the atomizing surface 11a is parallel to the first direction.

[0139] In other words, both the atomizing surface 11a and the mounting cavity 13aa extend along the first direction.

[0140] This increases the probability of the airflow in the mounting cavity 13aa coming into contact with the atomizing surface 11a during the flow in the first direction, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix.

[0141] In some embodiments, referring to FIG10, in a projection plane perpendicular to the first direction, the projection of the atomizing surface 11a is located outside the projection range of the air inlet 13d of the mounting cavity 13aa.

[0142] In other words, the atomizing surface 11a and the structure of the mounting base 13 for forming the air inlet 13d of the mounting cavity 13aa are offset in a direction perpendicular to the first direction.

[0143] This allows the airflow to flow in from the air inlet 13d of the mounting cavity 13aa without being blocked by the atomizing component 11 itself, which is conducive to the airflow flowing more smoothly through the atomizing surface 11a, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix.

[0144] In some embodiments where the atomizing surface 11a is parallel to the first direction and the projection of the atomizing surface 11a is located outside the projection range of the air inlet 13d of the mounting cavity 13aa, referring to Figures 4 and 10, in a projection plane perpendicular to the first direction, along the normal direction of the projection of the atomizing surface 11a, the distance between the end of the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is no greater than 1.1 mm. That is, the distance between the end of the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is L3, where L3 ≤ 1.1 mm.

[0145] Thus, within the aforementioned range, it is beneficial to improve the efficiency of aerosol particles leaving the mounting cavity 13aa with the airflow, reduce aerosol residue in the mounting cavity 13aa, and improve the user experience.

[0146] In some embodiments, the distance between the projected profile of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a ranges from 0.2 mm to 0.4 mm. That is, 0.2 mm ≤ L3 ≤ 0.4 mm. This further improves the efficiency of aerosol exiting the mounting cavity 13aa.

[0147] In the above embodiments, the specific value of the distance between the projected outline of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a can be 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, or 1.1mm.

[0148] It should be noted that the distance between the projection outline of the air inlet 13d and the projection of the atomizing surface 11a is 0mm, which means that a part of the projection outline of the air inlet 13d coincides with the projection of the atomizing surface 11a.

[0149] In some embodiments, referring to FIG9, at least a portion of the projection of the atomizing surface 11a is located within the projection range of the air outlet 13e of the mounting cavity 13aa in a projection plane perpendicular to the first direction.

[0150] In other words, the atomizing surface 11a and the structure of the air outlet 13e forming the mounting cavity 13aa are offset in a direction perpendicular to the first direction.

[0151] This allows the airflow to flow unobstructed towards the structure forming the air outlet 13e of the mounting cavity 13aa, which facilitates the smoother flow of air out of the mounting cavity 13aa and thus helps reduce the resistance to airflow.

[0152] In some embodiments, referring to Figures 3 and 4, the housing 12 is provided with an exhaust channel 12b, which extends along a first direction and connects the mounting cavity 13aa with the outside of the atomizer 10.

[0153] Thus, the airflow and aerosol are discharged from the atomizer 10 through the discharge channel 12b for the user to inhale.

[0154] In some embodiments, referring to Figures 3, 4, and 9, the atomizing surface 11a is parallel to the first direction. In a projection plane perpendicular to the first direction, the geometric center of the projection range of the air outlet 13e is the first center 13ea. The first center 13ea is located on the side of the projection of the atomizing surface 11a away from the atomizing component 11. Along the normal direction of the working plane, the distance between the first center 13ea and the atomizing surface 11a does not exceed 1.75mm. That is, the distance between the first center 13ea and the atomizing surface 11a is L4, where L4 ≤ 1.75mm.

[0155] This allows for a more compact structure of the atomizer 10 while also facilitating smoother airflow out of the mounting cavity 13aa.

[0156] The distance between the edge of the projected profile of the air outlet 13e on the working plane away from the first center 13ea and the working plane can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, etc.

[0157] In some embodiments, referring to FIG4, the distance between the atomizing surface 11a and the inner wall of the mounting cavity 13aa on the opposite side of the atomizing surface 11a ranges from 2 mm to 4.5 mm. That is, the distance between the atomizing surface 11a and the inner wall of the mounting cavity 13aa on the opposite side of the atomizing surface 11a is L5, where 2 mm ≤ L5 ≤ 4.5 mm.

[0158] This allows the cross-sectional dimensions of the mounting cavity 13aa to meet the flow rate requirements of the airflow, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix after the airflow enters the mounting cavity 13aa.

[0159] The specific distance between the atomizing surface 11a and the inner wall of the mounting cavity 13aa on the opposite side of the atomizing surface 11a can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, etc.

[0160] In some embodiments, referring to FIG10, on a projection plane perpendicular to the first direction, the projection of the air inlet 13d of the mounting cavity 13aa is rectangular, and the long side of the projection is parallel to the atomizing surface 11a.

[0161] This allows the airflow from the air inlet 13d of the mounting cavity 13aa to flow directly through the plane where the atomizing surface 11a is located, and increases the area of ​​the atomizing surface 11a that the airflow can flow through, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix.

[0162] In some embodiments, the cross-sectional area of ​​the air inlet 13d of the mounting cavity 13aa is greater than 3 mm². 2 (square millimetre, square millimeter).

[0163] This helps ensure that the airflow entering the mounting cavity 13aa meets the requirements and reduces the resistance encountered by the airflow entering the mounting cavity 13aa.

[0164] In some embodiments, referring to FIG4, along the first direction, the distance between the atomizing surface 11a and the air inlet 13d of the mounting cavity 13aa is greater than 0.2mm. That is, the distance between the atomizing surface 11a and the air inlet 13d of the mounting cavity 13aa is L6, where L6 > 0.2mm.

[0165] This allows the airflow to have sufficient space to diffuse after entering the mounting cavity 13aa and to contact the edge of the atomizing surface 11a, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix.

[0166] The specific value of the distance between the atomizing surface 11a and the air inlet 13d of the mounting cavity 13aa can be 0.21mm, 0.22mm, 0.23mm, 0.25mm, 0.26mm, 0.28mm, 0.3mm, 0.35mm, 0.4mm, etc.

[0167] This application provides an atomizer 10. Referring to Figures 1 to 4, 9 and 11, the atomizer 10 is provided with an air inlet channel 13ac, an atomizing chamber 10a and an air outlet channel 10b connected sequentially along the airflow direction. The atomizing chamber 10a extends along a first direction.

[0168] The atomizer 10 includes a housing 12, a mounting base 13, and an atomizing assembly 11.

[0169] Mounting base 13 includes at least a portion of an air inlet channel 13ac and at least a portion of an air outlet channel 10b, and housing 12 and mounting base 13 together enclose a liquid storage cavity 12a.

[0170] The atomizing component 11 and the mounting base 13 together form an atomizing cavity 10a. The atomizing component 11 has an atomizing surface 11a, which forms part of the inner wall of the atomizing cavity 10a. In a projection plane perpendicular to the first direction, at least a portion of the projection of the atomizing surface 11a is located within the projection range of the air outlet 13e of the atomizing cavity 10a.

[0171] Air from outside the atomizer 10 can form an airflow that enters the mounting base 13, enters from one end of the atomizing chamber 10a and flows out from the other end, eventually exiting the atomizer 10. The opening at the end where the airflow enters the atomizing chamber 10a is the air inlet 13d of the atomizing chamber 10a, and the opening at the end where the airflow exits the atomizing chamber 10a is the air outlet 13e of the atomizing chamber 10a.

[0172] In some embodiments 3, the atomizing assembly 11 includes a liquid guiding element 117 and an atomizing body 111. The atomizing body 111 is located on the surface of the liquid guiding element 117, and the aerosol generating matrix in the liquid storage chamber 12a can be conducted through the liquid guiding element 117 to the atomizing body 111 for atomization to form an aerosol. In these embodiments, the area of ​​the surface of the liquid guiding element 117 covered by the atomizing body is the atomizing surface 11a.

[0173] In other embodiments, the atomizing component includes an atomizing body 111, and a portion of the surface of the atomizing body 111 atomizes the aerosol matrix that comes into contact with it, and this portion of the surface is called the atomizing surface 11a.

[0174] It is understandable that the airflow in the atomizing chamber 10a flows along the extension direction of the atomizing chamber 10a, that is, along the first direction.

[0175] It is understandable that a portion of the airflow flowing in the first direction within the atomization chamber 10a can flow through the atomization surface 11a to mix with the atomized aerosol generation matrix to form an aerosol.

[0176] It is understood that at least a portion of the air outlet 13e of the atomizing chamber 10a is located on one side of the atomizing surface 11a along the first direction.

[0177] The atomizing surface 11a and the structure of the mounting base 13 for forming the air outlet 13e of the atomizing chamber 10a are offset in a direction perpendicular to the first direction.

[0178] In this embodiment, the atomizer 10, by ensuring that the projection of the atomizing surface 11a at least partially overlaps with the projection of the air outlet 13e of the atomizing cavity 10a, reduces the risk of airflow turbulence caused by obstruction or rebound due to the solid structure forming the air outlet 13e of the atomizing cavity 10a after flowing through the atomizing surface 11a in the first direction towards the air outlet 13e. This facilitates smoother airflow out of the atomizing cavity and reduces interference from turbulent airflow on subsequent airflow through the atomizing surface 11a. This also helps ensure that the mixing effect of subsequent airflow with the atomized aerosol generation matrix meets expectations and improves the efficiency of the airflow in carrying the aerosol out of the atomizing cavity 10a.

[0179] The atomizing surface 11a can atomize the aerosol generating matrix that comes into contact with it by means of heating or other methods.

[0180] The specific method of forming the atomizing chamber 10a is not limited.

[0181] For example, referring to FIG11, the mounting base 13 includes a mounting cavity 13aa and a mounting hole 13b. The mounting cavity 13aa extends along a first direction, and the mounting hole 13b is located on the side of the mounting cavity 13aa perpendicular to the first direction and connects the mounting cavity 13aa with the outside of the mounting base 13. The atomizing assembly 11 blocks the mounting hole 13b to form an atomizing cavity 10a together with the mounting base 13.

[0182] The atomizing component 11 blocks the mounting hole 13b, which on the one hand makes it difficult for the aerosol generating matrix in the liquid storage chamber 12a and the airflow in the atomizing chamber 10a to directly exchange and flow between the mounting channel and the liquid storage chamber 12a; on the other hand, the atomizing component 11 can absorb the aerosol generating matrix from the liquid storage chamber 12a and allow the generated aerosol to diffuse directly into the mounting chamber.

[0183] It is understandable that the opening formed by the connection between the mounting hole 13b and the atomizing chamber 10a is neither the air inlet 13d of the atomizing chamber 10a nor the air outlet 13e of the atomizing chamber 10a.

[0184] The atomizing surface 11a can be a flat surface or a curved surface.

[0185] In some embodiments, referring to Figures 4 and 9, in a projection plane perpendicular to the first direction, the geometric center of the projection range of the air outlet 13e of the atomizing chamber is the first center 13ea, which is located on the side of the projection of the atomizing surface 11a away from the atomizing component 11.

[0186] The first center 13ea is the geometric center of the geometric figure formed by the projection of the air outlet 13e.

[0187] In other words, the first center 13ea is located outside the projection of the atomizing component 11, and the first center 13ea and the projection of the atomizing component 11 are spaced apart along the relative direction between the first center 13ea and the atomizing surface 11a.

[0188] This allows more airflow within the atomizing chamber 10a to flow directly out of the atomizing chamber 10a along the first direction, ensuring that the flow rate of airflow out of the atomizing chamber 10a meets the demand and reducing suction resistance during the user's inhalation process.

[0189] In some embodiments, referring to FIG3, the atomizing surface 11a is parallel to the first direction.

[0190] In other words, the atomizing surface 11a is a plane and extends along the first direction.

[0191] This increases the probability of the airflow in the atomizing chamber 10a coming into contact with the atomizing surface 11a during the flow in the first direction, thereby improving the mixing effect between the airflow and the atomized aerosol generation matrix. It also helps to reduce the adverse effect of the atomizing surface 11a on the resistance of the airflow in the atomizing chamber 10a, making the airflow in the atomizing chamber smoother.

[0192] It is understandable that, since the atomizing surface 11a is parallel to the first direction, the projected outline of the atomizing surface 11a is a line segment in the projection plane perpendicular to the first direction.

[0193] In some embodiments, referring to Figures 4 and 9, the distance between the first center 13ea and the atomizing surface 11a along the normal direction of the atomizing surface 11a does not exceed 1.75 mm (millimeters). That is, the distance between the first center 13ea and the atomizing surface 11a is L4, where L4 ≤ 1.75 mm.

[0194] Referring to Figure 12, the vertical axis represents the output efficiency value, and the horizontal axis A1, A2, A3, A4, and A5 represent the distances between different first centers 13ea and atomizing surfaces 11a. Among them, A1 = 0 mm, A2 = 0.45 mm, A3 = 0.9 mm, A4 = 1.32 mm, and A5 = 1.75 mm.

[0195] As shown in Figure 12, the carry-out efficiency of aerosols in the small particle size range first increases with the increase of the L4 value, and then decreases after exceeding the value of A4; the carry-out efficiency of aerosols in the medium particle size range also increases with the increase of the L4 value, and the carry-out efficiency of the medium particle size range decreases significantly when the maximum distance exceeds A4; the carry-out efficiency of aerosols in the large particle size range also increases with the increase of the L4 value, and the carry-out efficiency of the large particle size range decreases significantly when the maximum distance exceeds A4.

[0196] As shown in Figure 12, the carry-out efficiency of each particle size range and the overall carry-out efficiency both meet the expected requirements.

[0197] Thus, within the aforementioned range, it is beneficial to improve the efficiency of aerosol particles leaving the atomization chamber 10a with the airflow, reduce aerosol residue in the atomization chamber 10a, and improve the user experience.

[0198] In some embodiments, the distance between the first center 13ea and the atomizing surface 11a ranges from 0.7 mm to 1.1 mm. That is, 0.7 mm ≤ L4 ≤ 1.1 mm. This further improves the efficiency of aerosol exiting the atomizing chamber 10a.

[0199] The specific distance between the first center 13ea and the atomizing surface 11a can be 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.45mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.3mm, 1.32mm, 1.4mm, 1.5mm, 1.75mm, etc.

[0200] It is understood that in the embodiment where the atomizing surface 11a is parallel to the first direction, referring to FIG4, since the first center 13ea is located on the side of the atomizing surface 11a whose projection is away from the atomizing component 11, the distance between the first center 13ea and the atomizing surface 11a along the normal direction of the atomizing surface 11a is L4, and the distance between the first center 13ea and the projection outline of the air outlet 13e located on the edge of the atomizing surface 11a away from the first center 13ea is L8, where L4 < L8.

[0201] In some embodiments, referring to FIG4, the atomizing surface 11a is parallel to the first direction, and the inner wall of the atomizing cavity 10a includes a first wall 10aa. Along the normal direction of the atomizing surface 11a, the first wall 10aa and the atomizing surface 11a are arranged at intervals, and the distance between the atomizing surface 11a and the first wall 10aa is 2mm to 4.5mm. That is, the distance between the atomizing surface 11a and the first wall 10aa is L5, where 2mm≤L5≤4.5mm.

[0202] This makes it difficult for the aerosol generated by the atomizing surface 11a to come into contact with the first wall 10aa, thus reducing the probability of aerosol recondensation and improving the efficiency of aerosol discharge from the atomizer 10.

[0203] The specific value of the distance between the atomizing surface 11a and the first wall 10aa can be 2mm, 2.5mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, or 4.5mm.

[0204] In some embodiments, the distance between the atomizing surface 11a and the first wall 10aa is 3 mm to 4 mm.

[0205] In this way, the probability of aerosols generated by the atomizing surface 11a coming into contact with the first wall 10aa and causing the aerosols to recondense is reduced, while also making the space of the atomizing chamber 10a more compact and improving the efficiency of airflow out of the atomizing chamber 10a.

[0206] It is understood that in some embodiments of the mounting base 13 including the mounting cavity 13aa, a portion of the inner wall of the mounting cavity 13aa forms a first wall 10aa.

[0207] In some embodiments, referring to Figures 4 and 9, in a projection plane perpendicular to the first direction, the projection of the atomizing surface 11a is located outside the projection range of the air inlet 13d of the atomizing cavity 10a.

[0208] In other words, the atomizing surface 11a and the structure of the air inlet 13d of the mounting base 13 for forming the atomizing chamber 10a are offset in a direction perpendicular to the first direction.

[0209] This allows the airflow to flow into the atomizing chamber 10a through the air inlet 13d without being blocked by the atomizing component 11 itself, which helps the airflow to flow more smoothly through the atomizing surface 11a, thereby improving the mixing effect between the airflow and the aerosol.

[0210] In some embodiments where the atomizing surface 11a is parallel to the first direction and the projection of the atomizing surface 11a is located outside the projection range of the air inlet 13d of the atomizing cavity 10a, referring to Figures 9 and 10, in the projection plane perpendicular to the first direction, along the normal direction of the atomizing surface 11a, the minimum distance between the projection profile of the air inlet 13d and the projection of the atomizing surface 11a is no greater than 1.1 mm. That is, the distance between the end of the projection profile of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is L3, where L3 ≤ 1.1 mm.

[0211] It is understood that in these embodiments, referring to FIG10, in the projection plane perpendicular to the first direction, the geometric center of the projection range of the air inlet 13d is the second center 13da. The second center 13da is located on the side of the projection of the atomizing surface 11a away from the atomizing component 11. Along the normal direction of the atomizing surface 11a, the distance between the second center 13da and the atomizing surface 11a is L9. The distance between the projection contour of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a is L3, where L3 < L9.

[0212] Thus, within the aforementioned range, it is beneficial to improve the efficiency of aerosol particles leaving the atomization chamber 10a with the airflow, reduce aerosol residue in the atomization chamber 10a, and improve the user experience.

[0213] In some embodiments, the distance between the projected profile of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a ranges from 0.2 mm to 0.4 mm. That is, 0.2 mm ≤ L3 ≤ 0.4 mm. This further improves the efficiency of aerosol exiting the atomizing chamber 10a.

[0214] It should be noted that the distance between the projection outline of the air inlet 13d and the projection of the atomizing surface 11a is 0mm, which means that a part of the projection outline of the air inlet 13d coincides with the projection of the atomizing surface 11a.

[0215] In some embodiments, the atomizing surface 11a is parallel to the first direction, and in the projection plane perpendicular to the first direction, along the normal direction of the atomizing surface 11a, the distance between the projection profile of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a does not exceed 1.1 mm.

[0216] Thus, within the aforementioned range, it is beneficial to improve the efficiency of aerosol particles leaving the atomization chamber 10a with the airflow, reduce aerosol residue in the atomization chamber 10a, and improve the user experience.

[0217] In some embodiments, referring to FIG13, the atomizing surface 11a is parallel to the first direction. In a projection plane perpendicular to the first direction, at least a portion of the projection of the atomizing surface 11a lies within the projection range of the air inlet 13d of the atomizing cavity 10a. Along the normal direction of the atomizing surface 11a, the distance between the end of the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a does not exceed 0.2 mm. That is, the distance between the end of the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is L3, where L3 ≤ 0.2 mm.

[0218] Thus, within the aforementioned range, it is beneficial to improve the efficiency of aerosol particles leaving the atomization chamber 10a with the airflow, reduce aerosol residue in the atomization chamber 10a, and improve the user experience.

[0219] In the above embodiments, the specific value of the distance between the projected outline of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a can be 0.05mm, 0.1mm, 0.15mm, 0.2mm, etc.

[0220] Referring to Figure 14, the vertical axis represents the output efficiency value. The horizontal axis, B1, B2, B3, B4, B5, and B6, represent the distances between the projected contours of different air inlets 13d and the projections of the end closest to the atomizing component 11 and the atomizing surface 11a. Specifically, B1 = -0.2 mm, B2 = 0 mm, B3 = 0.4 mm, B4 = 0.55 mm, B5 = 0.7 mm, and B6 = 1.1 mm.

[0221] As shown in Figure 14, the overall carry-out efficiency first increases as the air inlet 13d moves further away from the ceramic center, and then decreases after the value of L3 exceeds 1.1 mm. When the value of L3 is less than -0.2 mm, part of the carry-out efficiency is blocked by the atomizing component 11 at the air inlet 13d, and the carry-out efficiency of the medium and large particle size segments is lower than that of other L3 values ​​in this range. When the value of L3 is greater than 1.1 mm, the carry-out efficiency of the small and medium particle size segments is lower.

[0222] It should be noted that in Figure 14, the value of L3 is -0.2mm, which refers to an embodiment in which at least a portion of the projection of the atomizing surface 11a is located within the projection range of the air inlet 13d of the atomizing cavity 10a in the projection plane perpendicular to the first direction, and the distance between the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is 0.2mm along the normal direction of the atomizing surface 11a; the value of L3 is 0.4mm, which refers to an embodiment in which the projection of the atomizing surface 11a is located outside the projection range of the air inlet 13d of the atomizing cavity 10a in the projection plane perpendicular to the first direction, and the distance between the projection outline of the air inlet 13d near the atomizing component 11 and the projection of the atomizing surface 11a is 0.4mm along the normal direction of the atomizing surface 11a. In other words, the positive and negative values ​​of L3 represent two opposite directions along the normal direction of the atomizing surface 11a, respectively, and the distance between the projection profile of the air inlet 13d near the end of the atomizing component 11 and the projection of the atomizing surface 11a.

[0223] In some embodiments, along the first direction, the distance between the atomizing surface 11a and the air inlet 13d of the atomizing cavity 10a is greater than 0.2 mm. That is, the distance between the atomizing surface 11a and the air inlet 13d of the atomizing cavity 10a is L6, where L6 > 0.2 mm.

[0224] This allows the airflow to have enough space to diffuse after entering the atomization chamber 10a and to come into contact with the edge of the atomization surface 11a, thereby improving the mixing effect between the airflow and the aerosol.

[0225] In some embodiments, in the projection plane perpendicular to the first direction, part of the projection of the atomizing surface 11a is located within the projection range of the air outlet 13e of the atomizing cavity 10a, and part is located outside the projection range of the air outlet 13e of the atomizing cavity 10a.

[0226] This helps to reduce the difficulty of manufacturing the atomizing surface 11a of the atomizing component 11 and reduce manufacturing costs.

[0227] In other embodiments, in a projection plane perpendicular to the first direction, the projection of the atomizing surface 11a is entirely within the projection range of the air outlet 13e of the atomizing chamber 10a.

[0228] This allows the airflow and aerosol flowing through the atomizing surface 11a to continue flowing in the first direction and directly through the air outlet 13e, thereby improving the efficiency of carrying the aerosol out of the atomizing chamber 10a.

[0229] In some embodiments, referring to Figures 9, 15, 16 and 17, the projection range of the air outlet 13e in the projection plane perpendicular to the first direction is one of a circle, an ellipse, a square and a rectangle.

[0230] Figures 9 and 18 show an embodiment where the projection area of ​​the air outlet 13e is square, Figure 10 shows an embodiment where the projection area of ​​the air outlet 13e is circular, Figure 11 shows an embodiment where the projection area of ​​the air outlet 13e is elliptical, and Figure 12 shows an embodiment where the projection area of ​​the air outlet 13e is rectangular.

[0231] Thus, the regular shape of the air outlet 13e facilitates the smoother flow of air and aerosol out of the atomizing chamber 10a, reducing the resistance to airflow.

[0232] In some embodiments, the air outlet channel 10b is entirely located in the mounting base 13, meaning that the mounting base 13 is directly connected to the outside of the atomizer 10.

[0233] In other embodiments, referring to FIG3, the housing 12 is provided with a cavity, which is open on one side along a first direction. The mounting base 13 is sealed in the open position of the cavity so that the mounting base 13 and the housing 12 surround to form a liquid storage cavity 12a. The cavity is provided with a mounting post 121 extending along the first direction. The mounting post 121 is provided with a through discharge channel 12b to communicate with the outside of the atomizer 10. The mounting base 13 also includes a carry-out channel 13f, which communicates the atomizing cavity 10a and the outside of the mounting base 13 and is located downstream of the atomizing cavity 10a along the airflow direction. A part of the mounting post 121 is inserted into the carry-out channel 13f so that the discharge channel 12b communicates with the carry-out channel 13f. The discharge channel 12b and the carry-out channel 13f together form the air outlet channel 10b.

[0234] In this way, the aerosol discharged from the atomizing chamber 10a can be discharged from the atomizer 10 through the discharge channel 12b for the user to inhale.

[0235] It is understandable that the air outlet 13e of the atomizing chamber 10a corresponds to the inlet of the exhaust channel 13f.

[0236] In some embodiments with an exhaust channel 12b, referring to Figures 4 and 9, at least a portion of the projection of the atomizing surface 11a is located within the projection range of the exhaust channel 12b in a projection plane perpendicular to the first direction.

[0237] This allows aerosols to flow more smoothly into the emission channel 12b.

[0238] In the embodiment where the atomizing surface 11a is parallel to the first direction, referring to Figures 4 and 9, along the normal direction of the atomizing surface 11a, the distance between the first center 13ea and the atomizing surface 11a is L4, and the distance between the first center 13ea and the edge of the atomizing surface 11a opposite to the first center 13ea is L10, where L4 < L10.

[0239] This allows aerosols to flow more smoothly into the emission channel 12b.

[0240] It is understandable that, referring to Figures 4 and 9, L4 < L10 ≤ L8.

[0241] In some embodiments where a mounting cavity 13aa is provided, the outgoing channel 13f is connected to the mounting cavity 13aa.

[0242] In some embodiments where the air outlet 13e of the atomizing chamber 10a is rectangular, the projection of the outlet channel 13f in the projection plane perpendicular to the first direction is rectangular, and the projection of the mounting post 121 is circular or elliptical, so as to add a sealing structure between the mounting post 121 and the inner wall of the outlet channel 13f to improve the sealing performance.

[0243] In some implementations, referring to Figures 4 and 9, the atomizer 10 also includes a sealing sleeve 14, a portion of which is sandwiched between the mounting post 121 and the inner wall of the delivery channel 13f to improve sealing.

[0244] In the projection plane perpendicular to the first direction, the outer contour projection shape of the structure of the mounting column 121 forming the inlet of the discharge channel 12b is one of a circle, an ellipse, a square, and a rectangle. For example, referring to FIG9, the outer contour projection shape of the structure of the mounting column 121 forming the inlet of the discharge channel 12b is a circle.

[0245] In some embodiments, the area of ​​the projected region of the air outlet 13e in a projection plane perpendicular to the first direction is greater than 6.8 mm². 2 (square millimetre, square millimeter).

[0246] This helps to improve the efficiency of aerosol discharge from the atomizing chamber 10a, reduce the flow velocity of the airflow out of the atomizing chamber 10a, make the airflow smoother, and reduce the probability of abnormal noise generated during the airflow process.

[0247] The specific value of the projected area of ​​the air outlet 13e can be 6.81 mm². 2 6.85mm 2 6.9mm 2 7mm 2 7.1mm 27.2mm 2 7.3mm 2 7.4mm 2 7.5mm 2 .

[0248] In some embodiments where the atomizing surface 11a is parallel to the first direction, in a projection plane perpendicular to the first direction, referring to FIG17, the projection range of the air outlet 13e is rectangular and the long side of the rectangle is parallel to the atomizing surface 11a.

[0249] The longer side of a rectangle is the longer of the two perpendicular sides of the rectangle.

[0250] This helps to increase the range of contact between the airflow in the atomizing chamber 10a and the atomizing surface 11a, thereby improving the mixing effect between the airflow and the aerosol.

[0251] In some embodiments where the atomizing surface 11a is parallel to the first direction, referring to FIG10, in a projection plane perpendicular to the first direction, the projection range of the air inlet 13d of the atomizing component 11 is rectangular and the long side of the rectangle is parallel to the atomizing surface 11a.

[0252] This helps to increase the range of contact between the airflow in the atomizing chamber 10a and the atomizing surface 11a, thereby improving the mixing effect between the airflow and the aerosol.

[0253] In some embodiments, the area of ​​the projected region of the air inlet 13d of the atomizing component 11 in a projection plane perpendicular to the first direction is greater than 3.0 mm². 2 .

[0254] This helps ensure that the airflow entering the atomizing chamber 10a meets the requirements and reduces the resistance encountered by the airflow entering the atomizing chamber 10a.

[0255] The specific value of the cross-sectional area of ​​the air inlet 13d of the atomizing chamber 10a can be 3.1 mm. 2 3.2mm 2 3.3mm 2 3.4mm 2 3.5mm 2 3.6mm 2 3.8mm 2 4.0mm 2 4.2mm 2 4.5mm 2 5mm 2 wait.

[0256] In some embodiments, referring to FIG18, in a projection plane perpendicular to the first direction, the projection of the air inlet 13d of the atomizing cavity 10a at least partially overlaps with the projection of the air outlet 13e of the atomizing cavity 10a, so as to reduce the probability of turbulence generated by the airflow in the atomizing cavity.

[0257] This application provides an atomizer 10. Referring to Figures 1 to 3, 10, 11 and 19, the atomizer 10 includes a housing 12, a mounting base 13 and an atomizing component 11.

[0258] The mounting base 13 is provided with an airflow channel 13a and a mounting hole 13b. The airflow channel 13a passes through the mounting base 13, and the mounting hole 13b connects the airflow channel 13a with the outside of the mounting base 13. The housing 12 and the mounting base 13 together form a liquid storage cavity 12a.

[0259] The atomizing component 11 seals the mounting hole 13b. The atomizing component 11 includes an atomizing body 111, a liquid guide 117, and a liquid storage component 112. The airflow channel 13a passes through the mounting base 13. The liquid storage component 112 is in fluid communication with the liquid storage chamber 12a. Both the liquid storage component 112 and the liquid guide 117 are provided with pores for absorbing the aerosol generation matrix. The porosity of the liquid guide 117 is greater than that of the liquid storage component 112. The liquid guide 117 is located between the atomizing body 111 and the liquid storage component 112 and is in fluid communication with both.

[0260] The airflow channel 13a passes through the mounting base 13, meaning that the openings at both ends of the airflow channel 13a are connected to the outside of the mounting base 13.

[0261] Airflow can enter from one end of airflow channel 13a and exit from the other end.

[0262] The atomizing component 11 seals the mounting hole 13b, which on the one hand makes it difficult for the aerosol generating matrix in the liquid storage chamber 12a and the airflow in the airflow channel 13a to directly exchange and flow between the airflow channel 13a and the liquid storage chamber 12a; on the other hand, the atomizing component 11 can absorb the aerosol generating matrix from the liquid storage chamber 12a and mix the atomized aerosol generating matrix with the air in the airflow channel 13a to form an aerosol.

[0263] The atomizer 111 can convert the aerosol generating matrix that it contacts or absorbs into aerosols through heating or other means.

[0264] The atomizing body 111 is in fluid communication with the airflow channel 13a, so that the atomized aerosol matrix of the atomizing body 111 can be mixed with the airflow in the airflow channel 13a to form an aerosol.

[0265] At least a portion of the liquid storage component 112 is located within the liquid storage cavity 12a, such that the aerosol generating matrix within the liquid storage cavity 12a can come into contact with the liquid storage component 112, thereby absorbing and storing a portion of the aerosol generating matrix into the pores.

[0266] It is understandable that the aerosol matrix located in the pores, due to the capillary effect generated by its surface tension, adheres to the inner wall of the pores, making it difficult to detach from the pores and return to the liquid storage chamber 12a under the action of external forces such as gravity.

[0267] The liquid storage element 112 is in fluid communication with the atomizer 111, and at least some of the pores are in communication with each other, so that the aerosol generation matrix can pass through the liquid storage element 112 and be delivered to the liquid guide element 117 in fluid communication with the liquid storage element 112.

[0268] Understandably, because the porosity of the liquid guiding component 117 is greater than that of the liquid storage component 112, the aerosol generating matrix flows from the pores of the liquid storage component 112 into the pores of the liquid guiding component 117. In other words, a flow path of the aerosol generating matrix is ​​formed from the liquid storage component 112 → the liquid guiding component 117 → the atomizer 111.

[0269] As the atomizer 111 consumes the aerosol generating matrix, the aerosol generating matrix in the pores of the liquid storage component 112 can continuously flow into the pores of the liquid guide component 117. The aerosol generating matrix flowing out of the pores of the liquid guide component 117 comes into contact with the liquid guide component 117, so that the atomizer 111 can continuously atomize the aerosol generating matrix.

[0270] In this embodiment, the atomizer 10, by providing a liquid storage component 112, allows the liquid storage component 112 to store a portion of the aerosol generating matrix through contact with the aerosol generating matrix. This ensures that regardless of the orientation of the atomizer 10, a portion of the aerosol generating matrix can be provided to the atomizing body 111 through the liquid storage component 112. This reduces the probability that the atomizing body 111 will not be able to contact the aerosol generating matrix when the atomizer 10 is in any orientation, which is beneficial to improving the user experience.

[0271] The specific structure and material of the pores formed by the liquid storage component 112 are not limited, such as fiber structures woven or twisted from cotton, sponge, polyester, nylon and other chemical fibers.

[0272] It is understandable that the size of the pores in the liquid storage component 112 and the liquid guiding component 117 may or may not be visible to the naked eye.

[0273] In some embodiments, referring to Figures 10 and 19, the liquid reservoir 112 is attached to the liquid guide 117.

[0274] In this way, fluid communication is achieved between the liquid storage component 112 and the liquid guiding component 117, shortening the flow path of the aerosol generation matrix between the liquid storage component 112 and the liquid guiding component 117, reducing the risk of interruption in the supply of aerosol generation matrix to the liquid guiding component 117, and enabling the aerosol generation matrix stored in the liquid storage component 112 to come into contact with the atomizer 111 more promptly through the liquid guiding component 117, further reducing the probability of problems such as dry burning of the atomizer 111.

[0275] In some embodiments, referring to Figures 10 and 19, the liquid reservoir 112 is located on one side of the liquid guide 117 along the second direction, and in a projection plane perpendicular to the second direction, the projection of the liquid guide 117 is located within the projection range of the liquid reservoir 112.

[0276] This increases the area of ​​fluid communication between the liquid guide 117 and the liquid storage 112, thereby improving the effect of the liquid storage 112 in supplying the aerosol generation matrix to the liquid guide 117. In addition, it increases the volume of the liquid storage 112, thereby increasing the total volume of the pores in the liquid storage 112 and increasing the amount of aerosol generation matrix that can be stored in the liquid storage 112.

[0277] It is understandable that the liquid storage component 112 is located on one side of the liquid guiding component 117 along the second direction, and the atomizer 111 is located on the other side.

[0278] In some embodiments, referring to Figures 19, 20, and 21, the atomizing assembly 11 further includes a bracket 113. The bracket 113 includes a first mounting cavity 113a, a second mounting cavity 113b, and a connecting hole 113c. A portion of the first mounting cavity 113a is open and communicates with the airflow channel 13a. A portion of the second mounting cavity 113b is open and communicates with the liquid storage cavity 12a. The connecting hole 113c connects the first mounting cavity 113a and the second mounting cavity 113b. At least a portion of the liquid guide 117 is located in the first mounting cavity 113a, and at least a portion of the liquid storage component 112 is located in the second mounting cavity 113b.

[0279] The bracket 113 provides a mounting position for the liquid guide 117 and the liquid reservoir 112. The bracket 113 is fixed to the mounting base 13 to fix the positions of the atomizer 111 and the liquid reservoir 112.

[0280] During the assembly of the atomizing component 11, the liquid guide 117 can be installed into the first mounting cavity 113a through the open position of the first mounting cavity 113a, and the inner wall of the first mounting cavity 113a plays a role in constraining and positioning the liquid guide 117; through the open position of the first mounting cavity 113a, the atomizing body 111 can come into contact with the liquid guide 117.

[0281] During the assembly of the atomizing component 11, the liquid storage component 112 can be installed into the second mounting cavity 113b through the open position of the second mounting cavity 113b, and the inner wall of the second mounting cavity 113b plays a role in constraining and positioning the liquid storage component 112; through the open position of the second mounting cavity 113b, the liquid storage component 112 can achieve fluid communication with the liquid storage cavity 12a.

[0282] The connecting hole 113c connects the first mounting cavity 113a and the second mounting cavity 113b, so that the aerosol generation matrix can pass through the connecting hole 113c and be absorbed by the liquid guiding element 117 located in the first mounting cavity 113a.

[0283] In some embodiments, referring to FIG19, a portion of the liquid storage component 112 passes through the connecting hole 113c and contacts the liquid guide component 117, thereby utilizing the space within the connecting hole 113c, which is beneficial to increasing the amount of aerosol generation matrix that can be stored within the liquid storage component 112.

[0284] In some embodiments, referring to FIG19, the first mounting cavity 113a and the second mounting cavity 113b are spaced apart along the second direction, and both the first mounting cavity 113a and the second mounting cavity 113b are open along the second direction but their opening directions are opposite.

[0285] This allows for the simultaneous installation of the liquid guide 117 and the liquid reservoir 112 along the second direction during the assembly of the atomizing assembly 11, thereby improving assembly efficiency. Furthermore, the inner walls of the first mounting cavity 113a and the second mounting cavity 113b of the connecting hole can respectively restrict the relative positions of the liquid guide 117 and the liquid reservoir 112 in the second direction.

[0286] It is understandable that the connecting hole 113c penetrates the bracket 113 along the second direction.

[0287] In some embodiments, referring to FIG20, the bracket 113 is provided with a positioning post 1131 protruding in the second direction on at least one side of the second direction, so that during the automated assembly of the atomizing component 11, the positioning post 1131 can be used to identify the position of the liquid guide 117 and the liquid storage component 112 and fix the position of the bracket 113.

[0288] In some embodiments, referring to Figures 10 and 11, the mounting hole 13b extends along a second direction, with one side open and communicating with the airflow channel 13a, and the other side communicating with the liquid storage chamber 12a.

[0289] This facilitates the installation of the atomizing component 11 into the mounting hole 13b along the second direction during the assembly process, and simultaneously enables the atomizing body 111 mounted on the liquid guide 117 to be in fluid communication with the airflow channel 13a on one side along the second direction, while the liquid storage component 112 is exposed to the outside on the other side along the second direction, so that the liquid storage component 112 can be in fluid communication with the liquid storage chamber 12a after the subsequent assembly of the housing 12.

[0290] In some embodiments, referring to FIG19, the atomizing assembly 11 further includes a first sealing ring 114 and a second sealing ring 115. At least a portion of the first sealing ring 114 is disposed in the first mounting cavity 113a and sandwiched between the bracket 113 and the liquid guide 117, and the second sealing ring 115 is sandwiched between the bracket 113 and the mounting base 13.

[0291] It is understandable that both the first sealing ring 114 and the second sealing ring 115 can undergo elastic deformation to achieve the sealing function.

[0292] The first sealing ring 114 reduces the probability that the aerosol generation matrix flowing out of the liquid storage component 112 will leak into the airflow channel 13a through the gap between the support 113 and the liquid guide 117.

[0293] The second sealing ring 115 reduces the probability that the aerosol generation matrix in the liquid storage chamber 12a will leak into the airflow channel 13a through the gap between the bracket 113 and the mounting base 13.

[0294] The specific material of the first sealing ring 114 is not limited, such as silicone, rubber, etc.

[0295] The specific material of the second sealing ring 115 is not limited, such as silicone, rubber, etc.

[0296] In some embodiments, referring to Figures 21 and 22, the bracket 113 further includes a connecting hole 113d, which connects the first mounting cavity 113a to the outside of the bracket 113. The atomizing assembly 11 also includes a connector 116, which passes through the connecting hole 113d to connect the first sealing ring 114 and the second sealing ring 115. The first sealing ring 114, the second sealing ring 115 and the connector 116 are an integral structure.

[0297] In other words, the first sealing ring 114, the second sealing ring 115, and the connector 116 are different parts of the same component.

[0298] In this way, the first sealing ring 114, the second sealing ring 115 and the connector 116 can be installed on the bracket 113 simultaneously, which helps to simplify the assembly steps of the atomizing component 11 and improve assembly efficiency.

[0299] The specific method by which the first sealing ring 114, the second sealing ring 115, and the connector 116 form an integrated structure is not limited, such as injection molding, additive manufacturing, etc.

[0300] In some embodiments, referring to Figures 19 and 21, the bracket 113 includes a mounting plate 1132 and a first limiting plate 1133. A connecting hole 113c penetrates the mounting plate 1132 along a second direction. The first limiting plate 1133 is disposed on one side of the mounting plate 1132 along the second direction and extends along the second direction. There are two first limiting plates 1133, which are spaced apart to jointly enclose a first mounting cavity 113a and a connecting hole 113d. A first sealing ring 114 is sandwiched between the atomizing body 111 and the mounting plate 1132 along the second direction. A second sealing ring 115 is sandwiched between the mounting base 13 and the mounting plate 1132 along the second direction. The second sealing ring 115 is circumferentially disposed around the two first limiting plates 1133 away from the first mounting cavity 113a.

[0301] It is understandable that the first limiting plate 1133 is inserted between the first sealing ring 114 and the second sealing ring 115.

[0302] The first limiting plate 1133 can limit the position of the first sealing ring 114 and the second sealing ring 115.

[0303] During the assembly of the atomizing component 11, the first sealing ring 114, the second sealing ring 115 and the connector 116 can be assembled along the second direction, and then the atomizing body 111 can be assembled along the same direction.

[0304] This allows the liquid guide 117, bracket 113, first sealing ring 114, second sealing ring 115 and connector 116 to be assembled along the second direction during the assembly of the atomizing component 11, without the need for any other directions, which helps to improve assembly efficiency.

[0305] In some embodiments, referring to Figures 19 and 20, the bracket 113 further includes a second limiting plate 1134, which is disposed on the side of the mounting plate 1132 opposite to the first limiting plate 1133 along the second direction and extends along the second direction, and the second limiting plate 1134 surrounds to form a second mounting cavity 113b.

[0306] This allows the liquid storage component 112 to be assembled along the second direction, which helps improve assembly efficiency.

[0307] In some embodiments, referring to FIG20, the second limiting plate 1134 and the positioning post 1131 are located on the same side of the mounting plate 1132 along the second direction, so as to seal the mounting hole 13b of the assembled atomizing component 11 along the second direction.

[0308] In some embodiments, referring to Figures 3 and 23, the housing 12 has a cavity, which is open on one side along a first direction. At least a portion of the mounting base 13 is inserted into the cavity through the open position to form a liquid storage chamber 12a. The atomizer 10 also includes a sealing sleeve 14, which includes a sleeve body 141 and a first sealing rib 142. A portion of the mounting base 13 located inside the cavity covers the sleeve body 141. The sleeve body 141 has a through liquid passage hole 141a. The liquid storage component 112 is in fluid communication with the liquid storage chamber 12a through the liquid passage hole 141a. The first sealing rib 142 is located on the surface of the sleeve body 141 opposite to the mounting base 13 and is sandwiched between the sleeve body 141 and the housing 12. The first sealing rib 142 surrounds the circumference of the sleeve body 141 along the first direction and is located on the side of the liquid passage hole 141a near the open position of the cavity.

[0309] The first sealing rib 142 is a ring structure.

[0310] The sealing fit between the sealing sleeve 14 and the mounting base 13, and the sealing fit between the first sealing rib 142 and the housing 12, help reduce the risk of leakage of the aerosol generation matrix from the gap between the housing 12 and the mounting base 13.

[0311] The reservoir 112 is able to expose at least part of its surface to the reservoir cavity 12a through the clearance hole, so that the sealing sleeve 14 does not prevent the reservoir 112 from absorbing aerosols to form a matrix.

[0312] It is understood that, along the first direction, a portion of the sleeve body 141 and at least a portion of the first sealing rib 142 are located between the open position of the cavity and the atomizing assembly 11.

[0313] In some embodiments, referring to FIG23, there are multiple first sealing ribs 142, and the multiple first sealing ribs 142 are arranged along the second direction, which helps to further improve the sealing effect.

[0314] The specific number of the first sealing ribs 142 can be 1, 2, 3, 4, 5, etc.

[0315] In some embodiments, referring to Figures 19, 10 and 23, the sealing sleeve 14 further includes a limiting beam 144, which spans across the opposite sides of the liquid passage 141a. The limiting beam 144 and the mounting base 13 together form a limiting space, and at least a portion of the atomizing component 11 is located in the limiting space.

[0316] The limiting beam 144 is located inside the liquid storage cavity 12a.

[0317] Thus, the limiting beam 144 can restrict the relative movement between the atomizing component 11 and the mounting hole 13b, thereby helping to maintain the sealing between the atomizing component 11 and the mounting hole 13b.

[0318] The limiting beam 144 is fitted with the atomizing component 11 to reduce the probability of the atomizing component 11 moving relative to the mounting base 13.

[0319] In some embodiments, the limiting beam 144 is positioned across the opposite sides of the liquid passage 141a along the first direction to reduce the risk that the limiting beam 144 and the inner wall of the cavity may fail to limit the atomizing component 11 due to frictional deformation during the insertion of the sealing sleeve 14 into the cavity along the first direction with the mounting base 13.

[0320] In some embodiments, referring to Figures 3 and 23, the sealing sleeve 14 further includes a second sealing rib 143. The second sealing rib 143 is located on the surface of the sleeve body 141 opposite to the mounting base 13 and is sandwiched between the sleeve body 141 and the housing 12. The second sealing rib 143 is located on the side of the first sealing rib 142 away from the open position of the cavity and is connected to the first sealing rib 142 to jointly enclose and form a lateral sealing area 143a. The liquid passage hole 141a is located on the side of the sleeve body 141 perpendicular to the first direction, and at least a portion of the lateral sealing area 143a is located on the other side.

[0321] Due to the sealing effect of the first sealing rib 142 and the second sealing rib 143, it is difficult for the aerosol generation matrix to flow into the lateral sealing area 143a.

[0322] This helps reduce the amount of aerosol-generating matrix flowing into the narrow gap between the sealing sleeve 14 and the inner wall of the cavity, thereby improving the utilization rate of the aerosol-generating matrix in the storage chamber 12a. At the same time, with the first direction being approximately vertical, the second sealing rib 143 can act as a guide, directing the aerosol-generating matrix towards the liquid passage 141a to contact the storage component 112, thus improving the efficiency of the storage component 112 in absorbing the aerosol-generating matrix.

[0323] The number of second sealing ribs 143 is unlimited; there can be one or more, with multiple second sealing ribs 143 arranged in parallel to each other.

[0324] It is understood that in some embodiments where there are multiple first sealing ribs 142, the second sealing rib 143 is connected to the first sealing rib 142 at the open position furthest from the cavity.

[0325] In some embodiments, the sealing sleeve 14 is an integral structure, that is, the limiting beam 144, the first sealing rib 142, the second sealing rib 143 and the sleeve body 141 are different parts of the same component. This helps to improve the sealing performance, reduce the assembly difficulty and simplify the assembly steps.

[0326] Understandably, the sealing sleeve 14 can undergo elastic deformation to improve the sealing performance.

[0327] The specific material of the sealing sleeve 14 is not limited, such as rubber, silicone, etc.

[0328] In some embodiments, referring to Figures 3 and 19, a mounting post 121 is provided in the cavity, the mounting post 121 extends along a first direction, the mounting post 121 is provided with a through discharge channel 12b, a part of the mounting post 121 is inserted into the airflow channel 13a so that the discharge channel 12b communicates with the airflow channel 13a, and a part of the sleeve body 141 is sandwiched between the airflow channel 13a and the mounting post 121.

[0329] Thus, by using the sleeve body 141, a seal can be achieved between the mounting column 121 and the mounting base 13, reducing the probability that the aerosol generation matrix will leak from the gap between the mounting column 121 and the mounting base 13 into the discharge channel 12b and the airflow channel 13a.

[0330] In some embodiments, the aerosol generating apparatus further includes a power supply component electrically connected to the atomizing component 11 to provide electrical energy to the atomizing component 11 so that the atomizing component 11 converts the electrical energy into heat energy.

[0331] The various embodiments / implementations of this application can be combined with each other without creating contradictions.

For those skilled in the art, the embodiments of this application can have various modifications and variations.
