[0133] Example 1

[0134] Referring to Figure 1, this application provides an embodiment of an atomizer. The atomizer 100 includes a housing 1 and an atomizing component 2. The housing 1 is provided with a liquid storage chamber 11 for storing a liquid matrix. The atomizing component 2 is in fluid communication with the liquid storage chamber 11, thereby atomizing the liquid matrix to generate an aerosol.

[0135] In some embodiments, the atomizer 100 is a component of an aerosol generating device, which includes a power supply component (not shown) that is electrically connected to the atomizer 100 to provide electrical power to the atomizer 100, thereby enabling the atomizing component 2 to atomize the liquid matrix.

[0136] The power supply assembly includes a power source, which may include any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery. The power supply assembly may also include a circuit board electrically connected to the power source, on which at least one controller is disposed, for controlling the electrical power output of the power source. In some embodiments, the controller includes at least one microprocessor or microcontroller. The microprocessor or microcontroller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor.

[0137] In some embodiments, the liquid matrix is ​​liquid at room temperature. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include, but are not limited to, areca nut extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. The vitamin mixture may be a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited to. The atomizer 100 can be used in various fields, such as medical applications and electronic aerosol atomization.

[0138] In some embodiments, the atomizing assembly 2 includes a liquid guiding element 22 and a heating element 21, with the heating element 21 disposed adjacent to the liquid guiding element 22. The liquid guiding element 22 may be a porous body for guiding the liquid matrix into the atomization range of the heating element. The heating element 21 is used to heat the atomized liquid matrix, thereby generating an aerosol. Porous bodies include, but are not limited to, porous ceramics, cotton, nonwoven fabrics, gauze, and fibrous products.

[0139] In some embodiments, the liquid storage chamber 11 includes a first liquid storage chamber 111 and a second liquid storage chamber 112 that are isolated from each other, and both the first liquid storage chamber 111 and the second liquid storage chamber 112 are in fluid communication with the atomizing component 2.

[0140] The liquid matrix stored in different liquid storage chambers 11 can be different, so that when the atomizing component 2 atomizes the liquid matrix provided by different liquid storage chambers 11, it can produce aerosols with different flavors or aromas. The aerosol generating matrix stored in different liquid storage chambers 11 can be the same, so that when the atomizing component 2 atomizes the liquid matrix provided by different liquid storage chambers 11, it can produce aerosols with the same flavor or aroma.

[0141] In some embodiments, the atomizer 100 further includes a liquid storage element 3, which has a large number of pores and is capable of adsorbing a large amount of liquid matrix. The liquid storage element 3 is disposed in the liquid storage chamber 11, and at least partially of the liquid matrix stored in the liquid storage chamber 11 is retained in the liquid storage element 3, thereby preventing the liquid matrix from leaking out of the liquid storage chamber 11. The liquid storage element 3 includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0142] When the liquid storage chamber 11 includes a first liquid storage chamber 111 and a second liquid storage chamber 112 that are isolated from each other, the liquid storage element 3 includes a first liquid storage element 31 disposed in the first liquid storage chamber 111 and a second liquid storage element 32 disposed in the second liquid storage chamber 112.

[0143] It should be noted that the liquid storage chamber 11, including the first liquid storage chamber 111 and the second liquid storage chamber 112 which are isolated from each other, is optional rather than mandatory.

[0144] In some embodiments, the atomizer 100 further includes an air guide tube 4, which is in fluid communication with the atomizing component 2 and is capable of discharging the aerosol generated by the atomizing aerosol matrix from the atomizing component 2 out of the atomizer 100. The air guide tube 4 may extend longitudinally along the housing, and an aerosol channel extending longitudinally along the housing 1 is provided within the housing 1, at least partially defined in the air guide tube 4.

[0145] In some embodiments, the atomizer 100 further includes a mouthpiece 12 having an inhalation port 121 for discharging the aerosol generated by the atomizer 100. The mouthpiece 12 can be held in the mouth by a user, and when held in the mouth, the inhalation port 121 is positioned towards the user's oral cavity, so that the user can inhale the aerosol generated by the atomizer 100 by inhaling through the mouthpiece 12. The aerosol channel is in fluid communication with the inhalation port 121 to guide the aerosol to the inhalation port 121.

[0146] Furthermore, the suction nozzle 12 and the housing 1 are integrally injection molded. Even further, one end of the air guide tube 4 is connected to the suction nozzle 12 and communicates with the air intake 121, and the suction nozzle 12, the housing 1 and the air guide tube 4 are integrally injection molded.

[0147] In some embodiments, referring to Figures 2 and 3, the heating element 21 includes a first heating portion 211, a second heating portion 212, and a connecting portion 213. The connecting portion 213 is electrically connected to the first heating portion 211 and the second heating portion 212, thereby enabling the first heating portion 211 and the second heating portion 212 to be assembled as a whole. Furthermore, the first heating portion 211 and the second heating portion 212 are non-coplanar and spaced apart, resulting in the heating element 21 having a large atomization area.

[0148] In some embodiments, the heating element 21 is formed by stamping a metal sheet to reduce the production cost of the heating element 21 and improve the production efficiency of the heating element 21.

[0149] In some embodiments, the first heating portion 211 and the connecting portion 213 have the same thickness D. In some embodiments, the second heating portion 212 and the connecting portion 213 have the same thickness D. In some embodiments, the first heating portion 211 and the second heating portion 212 have the same thickness D.

[0150] In some embodiments, the first heating part 211 and the connecting part 213 have the same height H. In some embodiments, the second heating part 212 and the connecting part 213 have the same height H. In some embodiments, the first heating part 211 and the second heating part 212 have the same height H.

[0151] In some embodiments, the first heating part 211 and the second heating part 212 have the same width W.

[0152] In some embodiments, the first heating element 211 and the second heating element 212 have the same structural features. Furthermore, the first heating element 211 and the second heating element 212 have the same dimensions. Even further, the heating element 21 has a surface-symmetrical structure or a centrosymmetric structure.

[0153] In some embodiments, referring to Figures 2 and 3, the first heating part 211 and the second heating part 212 are respectively connected to opposite ends of the connecting part 213, and the first heating part 211 and the second heating part 212 extend toward the same side of the connecting part 213, so that the first heating part 211 and the second heating part 212 are arranged approximately face to face.

[0154] In some embodiments, the connecting portion 213 is formed by bending the first heating portion 211 and the second heating portion 212 from the same metal sheet, thereby providing lateral support between the first heating portion 211 and the second heating portion 212. The ends of the first heating portion 211 and the second heating portion 212 opposite to the connecting portion 213 are free ends. After assembly, the free ends are anchored by the first bracket 6, so that the connecting portion 213 can provide support force to make the first heating portion 211 and the second heating portion 212 approach or adhere closely to the corresponding liquid guiding element 22, so that the fit between the first heating portion 211 and the second heating portion 212 and the corresponding liquid guiding element 22 is tighter, preventing the heating element from warping or twisting during the heating process, which helps to improve the efficiency of the first heating portion 211 and the second heating portion 212 in heating and atomizing the liquid matrix on the liquid guiding element 22.

[0155] Referring to Figures 2 and 3, as one example of the heating element 21, the first heating portion 211 is disposed perpendicular to the connecting portion 213, and the second heating portion 212 is disposed perpendicular to the connecting portion 213, thereby constructing the heating element 21 into a U-shaped structure. In one example, the first heating portion 211 and the second heating portion 212 are disposed parallel to each other, and both the first heating portion 211 and the second heating portion 212 extend in a plane to form a flat heating portion; and in other examples, the first heating portion 211 and the second heating portion 212 are arranged to extend in a curved surface, thereby connecting with the connecting portion 213 and constructing a C-shaped structure. In another example, the first heating portion 211 and the second heating portion 212 are arranged at an angle to each other. The first heating portion 211 and the second heating portion 212 may form an inclined angle in the longitudinal direction, for example, the extending direction of the first heating portion 211 and the second heating portion 212 is inclined at an acute angle to the axis of the aerosol channel. The first heating part 211 and the second heating part 212 can also form an inclined angle in the lateral direction. For example, the first heating part 211 and the second heating part 212 are inclined to each other, and the angle between the two and the connecting part 213 is less than 90 degrees.

[0156] In some embodiments, the average resistance value per unit area of ​​the first heating part 211 and the average resistance value per unit area of ​​the second heating part 212 are greater than the average resistance value per unit area of ​​the connecting part 213.

[0157] For example, referring to Figures 2 and 3, the first heating part 211 includes a mesh structure, or the first heating part 211 is provided with multiple through holes to increase the average resistance value per unit area of ​​the first heating part 211. Similarly, the second heating part 212 includes a mesh structure, or the second heating part 212 is provided with multiple through holes to increase the average resistance value per unit area of ​​the second heating part 212.

[0158] In some embodiments, referring to Figures 2 and 3, the heating element 21 includes a first pin 214 and a second pin 215, which are used for electrical connection to a power supply. A first heating part 211 and a second heating part 212 are electrically connected between the first pin 214 and the second pin 215, so that the first heating part 211 and the second heating part 212 can be connected in series with the power supply.

[0159] Furthermore, the heating element 21 also includes a third pin 216 connected to the connection portion 213, the first heating portion 211 is electrically connected between the first pin 214 and the third pin 216, and the second heating portion 212 is electrically connected between the second pin 215 and the third pin 216.

[0160] The first pin 214 and the second pin 215 can be electrically connected to the same electrode of the power supply, and the third pin 216 can be electrically connected to the other electrode of the power supply, so that the third pin 216 becomes the common positive or common negative pin of the first heating part 211 and the second heating part 212.

[0161] In some embodiments, the controller can independently control the circuit connection between the first pin 214 and the power supply and independently control the circuit connection between the second pin 215 and the power supply, thereby independently controlling the power supply to provide electrical power to the first heating part 211 and the second heating part 212, so that the first heating part 211 and the second heating part 212 can independently heat the atomized liquid matrix.

[0162] In some embodiments, referring to Figures 4-8, the atomizer 100 further includes a first support 6 and electrodes 7, the electrodes 7 being used for electrically connecting pins and a power source. The number of electrodes 7 can be the same as the number of pins; for example, when including a first pin 214, a second pin 215, and a third pin 216, it can include a first electrode electrically connected to the first pin 214, a second electrode electrically connected to the second pin 215, and a third electrode electrically connected to the third pin 216.

[0163] The preferred electrode 7 and the atomizing component 2 are both held on the first support 6.

[0164] In some embodiments, referring to FIG7, the first bracket 6 is provided with a stepped hole 61 having a step 611. The first pin 214 includes a first bent end 2141, which is located in the stepped hole 61 and abuts against the step 611, such that the step 611 is located between the first bent end 2141 and the first heating part 211. The electrode 7 is riveted in the stepped hole 61 and abuts against the first bent end 2141, so that the electrode 7 and the first pin 214 can maintain a stable electrical connection without welding. At the same time, the first bent end 2141 can also prevent the first pin 2141 from exiting the stepped hole 61 before the electrode 7 is riveted into the stepped hole 61.

[0165] The second pin 215 can have the same structural features as the first pin 214. The third pin 216 can have the same structural features as the first pin 214. The number of stepped holes 61 can be the same as the number of electrodes 7, and multiple stepped holes 61 are arranged in a one-to-one correspondence with multiple electrodes 7.

[0166] In some embodiments, referring to FIG8, the electrode 7 includes a first electrode 71 electrically connected to a first pin 214, a second electrode 72 electrically connected to a second pin 215, and a third electrode 73 electrically connected to a third pin 216. The third electrode 73 is elongated and its shape has a symmetry line A. The first electrode 214 and the second electrode 215 are arranged alternately and symmetrically with respect to the symmetry line A of the third electrode 73. Thus, the atomizer 100 and the power supply assembly can have multiple different electrical connection directions. For example, the atomizer 100 can be inserted into the power supply assembly in two different orientations rotated 180 degrees, without the need for a foolproof design. In this embodiment, preferably, the third electrode 73 is electrically connected to the connection portion 213 of the heating element 21, the first electrode 71 is electrically connected to the first heating portion 211 of the heating element 21, and the second electrode 72 is electrically connected to the second heating portion 211 of the heating element 21.

[0167] In some embodiments, referring to Figures 2 and 3, the heating element 21 includes a hook-shaped fixing portion 217 for anchoring or holding the heating element 21 on the first bracket 6.

[0168] Furthermore, the first bracket 6 is partially fitted into the hook-shaped fixing part 217, thereby holding the heating element 21 on the first bracket 6.

[0169] The air inlet 121 is located at the proximal end of the atomizer 100, and the hook-shaped fixing part 217 is preferably located at the proximal end of the heating element 21, so that the first bracket 6 can overcome the gravity of the heating element 21 and support the heating element 21.

[0170] In some embodiments, referring to Figures 2 and 3, the fixing part 217 includes a first fixing part 2171 and a second fixing part 2172. The first fixing part 2171 is disposed on the same side as the first heating part 211, and the second fixing part 2172 is disposed on the same side as the second heating part 212, so as to ensure that the first heating part 211 can be disposed adjacent to the liquid guiding element 22, and to ensure that the second heating part 212 can be disposed adjacent to the liquid guiding element 22.

[0171] The fluid guiding element 22 can also be held on the first support 6. For example, the first support 6 is provided with a window that is in fluid communication with the liquid storage chamber, and at least a portion of the fluid guiding element 22 can be interference-filled in the window to maintain connection with the first support 6.

[0172] In some embodiments, referring to FIG5, the liquid guiding element 22 includes a first liquid guiding element 221 and a second liquid guiding element 222, which are held at a distance from each other on the first support 6. A first heating portion 211 is disposed adjacent to the first liquid guiding element 221, so that the first heating portion 211 is close to or in contact with the first liquid guiding element 221, such that the first heating portion 211 is mainly used to heat the liquid matrix in the first liquid guiding element 221 to generate an aerosol. Similarly, a second heating portion 212 is disposed adjacent to the second liquid guiding element 222, such that the second heating portion 212 is mainly used to heat the liquid matrix in the second liquid guiding element 222 to generate an aerosol.

[0173] Furthermore, referring to Figure 5, the first support 6 is provided with a first window 62 and a second window 63 spaced apart from each other. At least a portion of the first liquid guiding element 221 is held in the first window 62, and at least a portion of the second liquid guiding element 222 is held in the second window 63, thereby separating and holding the first liquid guiding element 221 and the second liquid guiding element 222. Preferably, the first window 62 and the second window 63 are arranged opposite to each other or symmetrically.

[0174] In some embodiments, referring to Figures 4 and 5, an atomizing chamber 64 for releasing aerosols and providing airflow is defined between the first heating element 211 and the second heating element 212. The atomizing chamber 64 is in fluid communication with the intake port 121. Heating by the heating element 21 causes volatile substances generated by the evaporation of the liquid matrix to combine with air primarily in the atomizing chamber 64 to form an aerosol. The atomizing chamber 64 may be defined within the first support 6.

[0175] The first heating part 211 and the second heating part 212 can be arranged facing the same atomizing chamber 64, so that the aerosol generated by the first heating part 211 heating the liquid matrix and the aerosol generated by the second heating part 212 heating the liquid matrix are mainly formed in the same atomizing chamber 64, and then the aerosol formed by either heating part can flow from the same atomizing chamber 64 to the air intake 121.

[0176] In some embodiments, when the liquid storage chamber 11 includes a first liquid storage chamber 111 and a second liquid storage chamber 112 that are isolated from each other, the first liquid guiding element 221 is configured to conduct the liquid matrix stored in the first liquid storage chamber 111 to the first heating part 211 for heating and atomization, and the second liquid guiding element 222 is configured to conduct the liquid matrix stored in the second liquid storage chamber 112 to the second heating part 212 for heating and atomization. Since the first heating part 211 and the second heating part 212 are disposed facing the same atomization chamber 64, when the first heating part 211 and the second heating part 212 simultaneously receive electrical power for heating, the aerosol generated by the first heating part 211 through heating and atomizing the liquid matrix stored in the first liquid storage chamber 111 can mix with the aerosol generated by the second heating part 212 through heating and atomizing the liquid matrix stored in the second liquid storage chamber 112 in the atomization chamber 64. In some alternative examples, the liquid matrix stored in the first liquid storage chamber 111 and the second liquid storage chamber 112 has different compositions or types, thereby providing the user with a richer mixed flavor when the first heating unit 211 and the second heating unit 212 are working simultaneously.

[0177] Of course, the controller can control the first heating part 211 and the second heating part 212 to heat up individually or both at the same time by controlling the on and off of the circuit between the three pins and the power supply.

[0178] In some embodiments, the central axis of the atomizing chamber 64 is substantially coincident with the central axis of the aerosol channel to reduce the obstruction of aerosol flowing from the atomizing chamber 64 into the intake port 121, reduce the generation of condensate, and reduce the retention loss of aerosol during the process of flowing from the atomizing chamber 64 into the intake port 121.

[0179] In the embodiment shown in Figure 1, the air outlet of the atomizing chamber 64 is located at the proximal end of the atomizing chamber 64. Furthermore, the air outlet of the atomizing chamber 64 is positioned towards the direction of the inlet 121.

[0180] In some embodiments, referring to FIG1, the first heating element 211 and the second heating element 212 are both arranged substantially parallel to the aerosol channel. In other embodiments, the first heating element 211 and / or the second heating element 212 are arranged inclined to the central axis of the aerosol channel.

[0181] In some embodiments, referring to FIG1, the atomizing chamber 64 and the air inlet 121 or the aerosol channel are arranged on the same central axis.

[0182] In some embodiments, the cross-sectional area of ​​the atomizing chamber 64 is approximately the same as the ventilation area of ​​the aerosol channel, or the width W1 of the atomizing chamber 64 is approximately the same as the width or inner diameter D1 of the aerosol channel, so as to reduce the obstruction of aerosol flowing from the atomizing chamber 64 into the aerosol channel and reduce the loss of aerosol during the process of aerosol flowing from the atomizing chamber 64 into the aerosol channel.

[0183] In some embodiments, referring to Figure 1, the first bracket 6 has a support portion 65, which is disposed facing the air guide pipe 4 or facing the air inlet 121, and is used to support the atomizing assembly 2. The support portion 65 has an airflow inlet 66 communicating with the atomizing chamber 64, through which outside air can be guided into the atomizing chamber 64. The airflow inlet 66 can be located between the first window 62 and the second window 63, or between the first heating part 211 and the second heating part 212. The airflow inlet 66 and the air outlet of the atomizing chamber 64 can be located on opposite sides of the atomizing chamber 64.

[0184] Furthermore, the airflow inlet 66 includes a first airflow inlet 661 disposed adjacent to the first heating section 211 to guide airflow across the surface of the first heating section 211, thereby increasing the mixing efficiency of volatile substances generated by the atomized liquid matrix of the first heating section 211 with air, and also preventing turbulence from forming near the surface of the first heating section 211 or in the atomization chamber 64. Even further, the airflow inlet 66 also includes a second airflow inlet 662 disposed adjacent to the second heating section 212 to guide airflow across the surface of the second heating section 212, thereby increasing the mixing efficiency of volatile substances generated by the atomized liquid matrix of the second heating section 212 with air, and also preventing turbulence from forming near the surface of the second heating section 212 or in the atomization chamber 64.

[0185] In some embodiments, referring to Figures 4 and 6, the first support 6 includes a first sidewall 67 defining the atomizing chamber, and a first positioning groove 671 is provided on the first sidewall 67. The heating element 21 includes a first positioning portion 218, and a first positioning portion 219 is disposed in the first positioning groove 671. When assembling the heating element 21 and the first support 6, the heating element 21 can be positioned by the first positioning portion 218 corresponding to the first positioning groove 671, so as to prevent the heating element 21 from twisting or misaligning during the assembly process, so that the heating element 21 can be accurately engaged on the first support 6, which is beneficial to improving the yield rate.

[0186] Furthermore, a second positioning groove 762 is provided on the first sidewall 67, and the heating element 21 also includes a second positioning part 219 disposed in the second positioning groove 672. By providing multiple positioning parts and multiple positioning grooves in a one-to-one correspondence, the engagement accuracy and engagement yield between the heating element 21 and the first bracket 6 are further improved.

[0187] In the embodiment shown in FIG3, the first positioning part 218 is connected to the end of the first heating part 211 opposite to the connecting part 213, thereby the first positioning part 218 helps to position the first heating part 211. The second positioning part 219 is connected to the end of the second heating part 212 opposite to the connecting part 213, thereby the second positioning part 219 helps to position the second heating part 212.

[0188] In some embodiments of this application, the first liquid guiding element 221 is first installed and held in the first window 62, and the second liquid guiding element 222 is installed and held in the second window 63. Then, the heating element 21 is placed in the atomizing chamber 64, and the first heating element 211 is positioned so that it is adjacent to the first liquid guiding element 221 by engaging with the first positioning groove 671 through the first positioning part 218. The first heating element 211 is positioned so that it is adjacent to the first liquid guiding element 221 by interfering with the first support 6 through the first fixing part 2171. This allows the first heating element 211 to remain close to or in contact with the first liquid guiding element 221, and also prevents the first heating element 211 from becoming loose. At the same time, the second heating element 212 is positioned so that it is adjacent to the second liquid guiding element 222 by engaging with the second positioning groove 672 through the second positioning part 219. The second fixing part 2172 is positioned so that it is adjacent to the second liquid guiding element 222 by interfering with the first support 6 through the second fixing part 2172. This allows the second heating element 212 to remain close to or in contact with the second liquid guiding element 222, and also prevents the second heating element 212 from becoming loose.

[0189] In the embodiment shown in FIG3, the first pin 214 is connected to the first positioning part 218, and the second pin 215 is connected to the second positioning part 219.

[0190] In some embodiments, referring to FIG4, the connecting portion 213 is disposed facing the first sidewall 67. Alternatively, the first support 6 further includes a second sidewall 68 disposed opposite to the first sidewall 67, the second sidewall 68 defining a portion of the boundary of the atomizing chamber 64, and the connecting portion 213 disposed adjacent to the second sidewall 68, preferably the connecting portion 213 being tightly fitted against the second sidewall 68. The connecting portion 213 is located between the first sidewall 67 and the second sidewall 68. The atomizing chamber 64 is disposed between the connecting portion 213 and the first sidewall 67.

[0191] Furthermore, the first window 62 and the second window 63 are both disposed between the first sidewall 67 and the second sidewall 68, and the atomizing chamber 64 is located between the first window 62 and the second window 63.

[0192] In some embodiments, as shown in Figures 1, 8 and 9, the atomizer 100 further includes a sealing seat 5, and a liquid storage chamber 11 is defined between the housing 1 and the sealing seat 5, thereby sealing the liquid storage chamber 11.

[0193] The sealing seat 5 may include a second support 51 and a seal 52, with at least a portion of the second support 51 disposed within and connected to the housing 1, and at least a portion of the seal 52 located between the second support 51 and the housing 1 to provide a seal between the second support 51 and the housing 1 to prevent leakage of the liquid matrix in the reservoir 11.

[0194] In some embodiments, the first bracket 6 is connected to the sealing seat 5, such that the first bracket 6, the sealing seat 5 and the atomizing component 2 held on the first bracket 6 form a whole, which can then be assembled with the housing 1, which helps to simplify the process flow of the atomizer 100, improve the production efficiency of the atomizer 100 and reduce the production cost of the atomizer 100.

[0225] The heating element 21a includes:

[0226] The first heating element 211a, the second heating element 212a, and the connecting element 213a are electrically connected, allowing the first heating element 211a and the second heating element 212a to be assembled as a single unit. Furthermore, the first heating element 211a and the second heating element 212a are non-coplanar and spaced apart, resulting in a larger atomization area for the heating element 21a.

Furthermore, the first heating element 211a and the second heating element 212a have the same dimensions.

[0281] The atomizing component 1 may include a liquid absorption component 12 and a heating element 11. The liquid absorption component 12 is used to guide the aerosol generating matrix to the heating element 11, so that at least a portion of the aerosol generating matrix in the liquid absorption component 12 can be atomized to generate aerosol under the heat released by the heating element 11.

[0282] In some embodiments, the atomizer 200 includes a housing 2, the housing 2 having a storage cavity 21 for storing an aerosol generation matrix. The atomizing component 1 is in fluid communication with the storage cavity 21, so that the atomizing component 1 can atomize the aerosol generation matrix contained in the storage cavity 21 to generate an aerosol.

[0283] In some embodiments, the atomizer 200 further includes an air guide tube 3, which guides the aerosol generated by the atomizing aerosol matrix of the atomizing component 1 to the air outlet 41 of the atomizer 200, so that the aerosol can flow out of the atomizer 200 through the air outlet 41. The atomizing component 1 may be disposed inside the housing 2.

[0284] It should be noted that the outer shell 2 has a proximal end 51 and a distal end 52 arranged opposite each other in the longitudinal direction, and the air outlet 41 of the atomizer 200 can be arranged on the proximal end 51 of the outer shell 2.

[0285] In some embodiments, as shown in FIG17, the atomizer 200 further includes a support assembly 6, at least a portion of the atomizing component 1 is disposed in the support assembly 6, and the support assembly 6 has a first inlet 611, the first inlet 611 being able to guide at least a portion of the aerosol generation matrix in the storage cavity 21 to the atomizing component 1 for atomization.

[0286] In some embodiments, the heating element 11 includes a first heating section 111, which can generate Joule heating when it receives current, thereby atomizing the aerosol generation matrix. Of course, the first heating section 111 can also generate other energy besides Joule heating, such as microwaves, when it receives current or voltage, thereby increasing the molecular kinetic energy or thermal energy of the aerosol generation matrix, so that the aerosol generation matrix is ​​atomized.

[0287] The first heating section 111 is provided corresponding to the first inlet 611. The first heating section 111 can be mainly used to atomize at least part of the aerosol generation matrix introduced by the first inlet 161.

[0288] In order to increase the atomization efficiency of the atomizer 200, the heating element 11 may also include a second heating element 112 that is spaced apart from the first heating element 111. By increasing the number of heating elements, the atomization area of ​​the atomization assembly 1 is increased, thereby improving the atomization efficiency of the atomizer 200 and increasing the amount of aerosol.

[0289] When the second heating unit 112 receives an electric current, it can generate Joule heating, thereby atomizing the aerosol generation matrix. Of course, when the second heating unit 112 receives an electric current or voltage, it can also generate other energies besides Joule heating, such as microwaves, thereby increasing the molecular kinetic energy or thermal energy of the aerosol generation matrix, thus atomizing the aerosol generation matrix.

[0290] To prevent dry burning, the support assembly 6 may also have a second inlet 621, which can guide at least a portion of the aerosol generation matrix in the storage cavity 21 to the atomizing assembly 1 for atomization. Furthermore, a second heating unit 112 is provided corresponding to the second inlet 621, and the second heating unit 112 can be mainly used to atomize at least a portion of the aerosol generation matrix introduced by the second inlet 621.

[0291] In some embodiments, the support assembly 6 has an atomizing chamber 63 in which aerosol is mainly formed. The first heating element 111 and the second heating element 112 can both be disposed facing the atomizing chamber 63, so that at least a portion of the aerosol generated by the atomization of the first heating element 111 and at least a portion of the aerosol generated by the atomization of the second heating element 112 can be formed in the same atomizing chamber 63. The atomizing chamber 63 can be connected to the air outlet 41 via the air guide tube 3. Preferably, at least two of the atomizing chamber 63, the air guide tube 3, and the air outlet 41 are arranged along a common central axis.

[0292] In some embodiments, referring to Figures 21, 23, 24, and 28, the heating element 11 further includes a connecting portion 113 / 113', which is electrically connected to the first heating portion 111 and the second heating portion 112. At least one of the first heating portion 111 and the second heating portion 112 is not coplanar with the connecting portion 113 / 113'.

[0293] In the embodiments shown in Figures 24 and 28, the first heating element 111 and the second heating element 112 are connected on opposite sides of the connecting portion 113 / 113', or the first heating element 111 and the second heating element 112 are arranged face to face, so that the heating element 11 is approximately U-shaped. Based on this, the atomizing chamber 63 can be located between the first heating element 111 and the second heating element 112.

[0294] In some embodiments, referring to FIG17, the support assembly 6 further includes a first base 64, which supports the heating element 11, thereby allowing at least a portion of the heating element 11 to be held within the support assembly 6. For ease of description, the surface of the first base 64 facing the proximal end 51 is defined as the mounting surface 641, and the surface of the first base 64 facing away from the proximal end 51 is defined as the base surface 642. The first heating portion 111 and the second heating portion 112 may be located on the same side as the mounting surface 641. In other words, the atomizing chamber 62 may be located on the same side as the mounting surface 641.

[0295] In some embodiments, as shown in Figures 17 and 31, a vent 643 communicating with an atomizing chamber 63 is provided on the first base 64. Along the airflow direction, the vent 643 is located upstream of the atomizing chamber 63, and the vent 643 can guide the airflow into the atomizing chamber 63.

[0296] In some embodiments, referring to Figures 29 and 30, the first heating part 111 and the second heating part 112 both extend from the connecting part 113' toward the proximal end 51, such that the connecting part 113' is located between the first heating part 111 / the second heating part 112 and the distal end 52, and the atomizing chamber 63 is located between the connecting part 113' and the air outlet 41, and the connecting part 113' is horizontally arranged and extends laterally.

[0297] Therefore, the heating element 11 can be moved by driving the connecting part 113', and then the connecting part 113' can be placed horizontally on the first base 64. The connecting part 113' can then be pressed through the space between the first heating part 111 and the second heating part 112, so that the connecting part 113' is tightly against the first base 64, or the first pin 114, the second pin 115, and / or the third pin 116 can pass through the first base 64, thereby keeping the heating element 11 on the first base 64, that is, mounting the heating element 11 on the bracket assembly 6. Compared to a vertically arranged connecting part 113, a horizontally arranged or laterally arranged connecting part 113' has a lower center of gravity and / or a larger force-bearing area, thereby effectively preventing the connecting part 113' from bending and deforming.

[0298] In some embodiments, referring to Figures 20 and 26, the vent 643 includes a first vent 6431 disposed near the first heating part 111 and a second vent 6432 disposed near the second heating part 112. Therefore, the airflow entering the atomizing chamber 63 through the first vent 6431 is more likely to concentrate towards the first heating part 111 than the airflow entering the atomizing chamber 63 through the second vent 6432, and the airflow entering the atomizing chamber 63 through the second vent 6432 is more likely to concentrate towards the second heating part 112 than the airflow entering the atomizing chamber 63 through the first vent 6431.

[0299] In some embodiments, as shown in Figures 20 and 26, the first base 64 includes a base 645 and a guide member 644 disposed between the first vent 6431 and the second vent 6432.

[0300] The guide member 644 has a first guide surface 6441 corresponding to the first vent 6431. The first guide surface 6441 is inclined along the airflow direction or relative to the surface where the first heating part 111 is located, so as to guide the airflow that enters the atomizing chamber 63 through the first vent 6431 to be blown obliquely toward the first heating part 111.

[0301] As an example, referring to FIG20, at least a portion of the first guide surface 6441 extends in the atomizing chamber 63, so that the first guide surface 6441 can continue to guide the airflow obliquely towards the first heating part 111 within the atomizing chamber 63, which is beneficial to concentrate more airflow towards the central region of the first heating part 111, thereby also helping to reduce the temperature of the central region of the first heating part 111, which is beneficial to prevent the central region of the first heating part 111 from dry burning.

[0302] As an example, referring to FIG27, at least a portion of the first guide surface 6441 is located on the same side as the base surface 642 and extends beyond the base surface 642 to guide the airflow obliquely into the first vent 6431, thereby enabling the airflow to be obliquely blown toward the first heating part 111.

[0303] As an example, the first guide surface 6441 at least partially defines a portion of the boundary of the first vent 6431.

[0304] In some embodiments, as shown in Figures 20 and 26, the guide member 644 has a second guide surface 6442 provided corresponding to the second vent 6432. The second guide surface 6442 is inclined along the airflow direction or inclined relative to the surface where the second heating part 112 is located, so as to guide the airflow that enters the atomizing chamber 63 through the second vent 6432 to be blown obliquely toward the second heating part 112.

[0305] As an example, referring to FIG20, at least a portion of the second guide surface 6442 extends in the atomizing chamber 63, so that the second guide surface 6442 can continue to guide the airflow obliquely towards the second heating part 112 within the atomizing chamber 63, which is beneficial to concentrate more airflow towards the central region of the second heating part 112, thereby also helping to reduce the temperature of the central region of the second heating part 112, which is beneficial to prevent the central region of the second heating part 112 from dry burning.

[0306] As an example, referring to FIG27, at least a portion of the second guide surface 6442 is located on the same side as the base surface 642 and extends beyond the base surface 642 to guide the airflow obliquely into the second vent 6432, thereby enabling the airflow to be obliquely blown toward the second heating part 112.

[0307] As an example, the second guide surface 6442 at least partially defines a portion of the boundary of the second vent 6432.

[0308] The first guide surface 6441 and / or the second guide surface 6442 may include an inclined plane. The first guide surface 6441 and / or the second guide surface 6442 may include an arc surface.

[0309] Preferably, referring to Figures 20 and 26, the flow guide 644 is configured as a wedge-shaped structure, such that the first flow guide surface 6441 and the second flow guide surface 6442 are located on opposite sides of the flow guide 644. More preferably, the first flow guide surface 6441 and the second flow guide surface 6442 have approximately the same area, and the area of ​​the first flow guide surface 6441 and the second flow guide surface 6442 is larger than the area of ​​the other surfaces of the flow guide 644.

[0310] In some embodiments, referring to Figures 26 and 27, the guide member 644 extends away from the proximal end 51, such that the guide member 644 is located outside the atomizing chamber 63, thereby allowing the connecting portion 113' to extend in a straight line or along a plane between the first heating portion 111 and the second heating portion 112 while being horizontally arranged and closely attached to the mounting surface 641, so as to reduce the lateral extension length of the connecting portion 113'.

[0311] In some embodiments, the vent 643 is formed on the base 645, or the vent 643 is located between the guide member 644 and the base 645. In the embodiments shown in Figures 23 and 27, the first vent 6431 and the second vent 6432 are disposed between the base 645 and the guide member 644, and the first vent 6431 and the second vent 6432 are independently located on opposite sides of the guide member 644.

[0312] In some embodiments, referring to FIG28, the connecting portion 113' is horizontally connected to the first base 64. The guide member 644 includes a first support surface 6411 disposed towards the proximal end 51, and the base 645 includes a second support surface 6412 disposed towards the proximal end 51. The connecting portion 113' is at least partially connected to the first support surface 6411 and / or the second support surface 6412. Preferably, the first support surface 6411 and the second support surface 6412 are flush. Preferably, the connecting portion 113' is partially connected to the first support surface 6411 and partially connected to the second support surface 6412. The mounting surface 641 includes the second support surface 6412; in some embodiments, the mounting surface 641 also includes the first support surface 6411.

[0313] In some embodiments, as shown in Figures 29 and 30, the connecting part 113' is horizontally arranged and connected to the first base 64, and the heating element 11 is also provided with a hollow hole 1131 for connecting the vent hole 643 and the atomizing chamber 63.

[0314] As an example, the perforation 1131 is formed on the connecting part 113', thereby guiding the airflow from the vent 643 to the atomizing chamber 63.

[0315] As an example, the vent 643 includes a first vent 6431 disposed near the first heating part 111, and the perforated hole 1311 includes a first perforated hole opened between the connecting part and the first heating part 111. The first perforated hole is disposed corresponding to the first vent 6431, thereby guiding the airflow from the first vent 6431 to the atomizing chamber 63.

[0316] As an example, the vent 643 includes a second vent 6432 disposed near the second heating part 112, and the perforation 1131 includes a second perforation formed between the connecting part 113' and the second heating part 112. The second perforation is disposed corresponding to the second vent 6432, thereby guiding the airflow from the second vent 6432 to the atomizing chamber 63.

[0317] The first and second perforated holes can be spaced apart by the connecting part 113'.

[0318] In other embodiments, the first and second perforations may also be formed on the connecting portion 113'.

[0319] In some embodiments, as shown in Figures 21 and 27, the support assembly 64 further includes a flexible member 65 disposed on the first base 64. The flexible member 65 abuts against the first heating part 111, so that the first heating part 111 is in close contact with the corresponding liquid absorption assembly 12, for example, so that the first heating part 111 is in close contact with the first liquid absorption assembly 121, thereby improving the atomization efficiency of the first heating part 111.

[0320] The flexible member 65 can also simultaneously abut against the second heating part 112, so that the second heating part 112 is in close contact with the corresponding liquid suction component 12, for example, so that the second heating part 112 is in close contact with the second liquid suction component 122, thereby improving the atomization efficiency of the second heating part 112. Of course, different flexible members 65 can also be used to abut against the first heating part 111 and the second heating part 112 respectively.

[0321] The flexible member 65 is elastic, so that when the flexible member 65 comes into contact with the heating part, the flexible member 65 makes soft contact with the heating part, which helps to reduce damage to the heating part when the two come into contact. The flexible member 65 may include a silicone product.

[0322] In some embodiments, referring to Figures 21, 26, and 33, the support assembly 6 includes a first sub-support 61 and a second sub-support 62. The first sub-support 61 and the second sub-support 62 are manufactured independently and can be connected to each other by assembly. After the first sub-support 61 and the second sub-support 62 are connected to each other, at least a portion of the atomizing component 1 is held or clamped between the first sub-support 61 and the second sub-support 62, and at least a portion of the atomizing chamber 63 may also be located between the first sub-support 61 and the second sub-support 62. In other words, after the first sub-support 61 and the second sub-support 62 are connected to each other, a holding cavity for mounting the atomizing component 1 is defined between the first support and the second support.

[0323] The first sub-support 61 defines a first inlet 611, and the second sub-support 62 defines a second inlet 621. The first inlet 611 and the second inlet 621 can independently receive the aerosol generating matrix from the storage cavity 21, and then guide the aerosol generating matrix in the storage cavity 21 to the atomizing component 1. Therefore, when at least one of the first inlet 611 and the second inlet 621 is open, the aerosol generating matrix stored in the storage cavity 21 can be guided to the atomizing component 1, and then atomized by the atomizing component 1 to generate aerosol.

[0324] In some embodiments, referring to Figures 21, 26, and 33, the liquid absorption assembly 12 includes a first liquid absorption assembly 121 and a second liquid absorption assembly 122 that are independently disposed of each other. The first liquid absorption assembly 121 is disposed corresponding to the first heating part 111, which is mainly used to atomize the aerosol generation matrix on the first liquid absorption assembly 121. The second liquid absorption assembly 122 is disposed corresponding to the second heating part 112, which is mainly used to atomize the aerosol generation matrix on the second liquid absorption assembly 122.

[0325] In some embodiments, the first sub-support 61 has a first holding cavity 612 for holding the first liquid absorption assembly 121, and the heating element 11 can be held on the first base 64, such that the heating element 11 and the first liquid absorption assembly 121 can be assembled with the support assembly 6 respectively. Further, the second sub-support 62 has a second holding cavity 622 for holding the second liquid absorption assembly 122, so that the first liquid absorption element 121, the heating element 11, and the second liquid absorption element 122 can be assembled with the support assembly 6 independently of each other.

[0326] In some embodiments, the process of combining the support assembly 6 with the atomizing assembly 1 includes: (1) obtaining the mutually discrete atomizing assembly 1, the first sub-support 61 and the second sub-support 62; (2) connecting the first sub-support 61 and the second sub-support 62, wherein after the first sub-support 61 and the second sub-support 62 are connected to each other, a retaining cavity is formed between the first sub-support 61 and the second sub-support 62; and (3) assembling at least a portion of the atomizing assembly 1 into the retaining cavity for retention.

[0327] In some embodiments, the assembly process of the support assembly 6 and the atomizing assembly 1 includes: (1) obtaining the mutually discrete atomizing assembly 1, the first sub-support 61, and the second sub-support 62; (2) assembling the atomizing assembly 1 with the first sub-support 61, wherein the first sub-support 61 and the second sub-support 62 are still mutually discrete; (3) connecting the first sub-support 61 and the second sub-support 62, such that at least a portion of the atomizing assembly 1 is enclosed between the first sub-support 61 and the second sub-support 62, and the atomizing assembly 1 is connected to the first inlet 611 and the second inlet 621. This facilitates easier and more convenient assembly of the atomizing assembly 1 between the first sub-support 61 and the second sub-support 62, and also reduces damage to the atomizing assembly 1 during assembly.

[0328] In some embodiments, the process of combining the support assembly 6 and the atomizing assembly 1 includes: (1) obtaining a mutually discrete heating element 11, a first liquid absorption assembly 121, a second liquid absorption assembly 122, a first sub-support 61, and a second sub-support 62; (2) assembling the first liquid absorption element 121 into a first holding cavity 612 defined by the first sub-support 61, and assembling the second liquid absorption element 122 into a second holding cavity 622 defined by the second sub-support 62; (3) combining the heating element 11 with the first sub-support 61, at which time the first sub-support 61 and the second sub-support 62 are still mutually discrete; (4) connecting the first sub-support 61 and the second sub-support 62, such that at least a portion of the heating element 11 is enclosed between the first sub-support 61 and the second sub-support 62, and the first heating part 111 is disposed corresponding to the first liquid absorption element 121, and the second heating part 112 is disposed corresponding to the second liquid absorption element 122. Thus, the atomizing assembly 1 is formed after the first sub-support 61 and the second sub-support 62 are connected. The assembly process provided in this embodiment helps to automate the assembly of the bracket assembly 6 and the atomizing assembly 1, thereby significantly improving the production efficiency of the atomizer 200.

[0329] Furthermore, before connecting the first sub-support 61 and the second sub-support 62, the heating element 11 can be assembled on the first base 64, so that the heating element 11 is held by the first base 64. Then, the heating element 11 is combined with the first sub-support 61 by connecting the first base 64.

[0330] Furthermore, when the first sub-support 61 is connected to the second sub-support 62, the first base 64 is also connected to the second sub-support 62.

[0331] In some embodiments, the first sub-support 61 and the second sub-support 62 are directly physically connected when they are connected to each other. In some embodiments, the first sub-support 61 and the second sub-support 62 are connected through a first base 64, and the first sub-support 61 and the second sub-support 62 may not have direct contact, or they may have direct physical contact.

[0332] In some embodiments, referring to Figures 20 and 26, the first sub-support 61 includes a third sidewall 613, on which a first outlet 614 is provided for connecting the first inlet 611 and the atomizing assembly 1. The first liquid-absorbing assembly 121 is sandwiched between the third sidewall 613 and the first heating part 111. The third sidewall 613 defines a portion of the boundary of the first holding cavity 612, and the third sidewall 613 can abut against the first liquid-absorbing assembly 121 in the lateral direction. The first outlet 614 is formed on the third sidewall 613, so that the first liquid-absorbing assembly 121 can conduct aerosol generation matrix to the first heating part 111 in the lateral direction.

[0333] In some embodiments, the first liquid absorption assembly 121 includes a first liquid absorption element 1211 and a second liquid absorption element 1212 stacked laterally. The first liquid absorption element 1211 abuts against a third sidewall 613, and the second liquid absorption element 1212 is disposed in close contact with the first heating portion 111. The second liquid absorption element 1212 is configured to conduct at least a portion of the aerosol generating matrix on the first liquid absorption element 1211 to the first heating portion 111. The first liquid absorption element 1211 and the second liquid absorption element 1212 are independent of each other and are stacked laterally, which helps to increase the liquid-locking capacity of the first liquid absorption assembly 121 and helps to prevent leakage of the aerosol generating matrix through the first liquid absorption assembly 121.

[0334] In some embodiments, when the first absorbent assembly 121 is at least partially held in the first retaining cavity 612, the first absorbent assembly 121 is held against the wall defining the first retaining cavity 612 to prevent leakage of the aerosol-generating matrix along the wall defining the first retaining cavity 612. The first absorbent assembly 121 may be interference-fitted into the first retaining cavity 612. Of course, in other embodiments, the size of the first absorbent assembly 121 may be approximately the same as the size of the first retaining cavity 612. After absorbing the aerosol-generating matrix, the first absorbent assembly 121 expands, thereby compressing the wall defining the first retaining cavity 612 to achieve a seal and prevent leakage of the first absorbent assembly 121 along the wall defining the first retaining cavity 612.

[0335] In some embodiments, the second sub-support 62 includes a fourth sidewall 623, on which a second outlet 624 is provided for communicating with the second inlet 621 and the atomizing assembly 1. The second liquid-absorbing assembly 122 is sandwiched between the fourth sidewall 623 and the second heating part 112. The fourth sidewall 623 defines a portion of the boundary of the second holding cavity 622 and is capable of laterally abutting against the second liquid-absorbing assembly 122. The second outlet 624 is formed on the fourth sidewall 623, so that the second liquid-absorbing assembly 122 can laterally conduct aerosol generation matrix to the second heating part 112.

[0336] In some embodiments, the second liquid absorption assembly 122 includes a third liquid absorption element 1221 and a fourth liquid absorption element 1222 stacked laterally. The third liquid absorption element 1221 abuts against a fourth sidewall 623, and the fourth liquid absorption element 1222 is disposed in close contact with the second heating portion 112. The fourth liquid absorption element 1222 is configured to conduct at least a portion of the aerosol generating matrix on the third liquid absorption element 1221 to the second heating portion 112. The third liquid absorption element 1221 and the fourth liquid absorption element 1222 are independent of each other and are stacked laterally, which helps to increase the liquid-locking capacity of the second liquid absorption assembly 122 and helps to prevent leakage of the aerosol generating matrix through the second liquid absorption assembly 122.

[0337] In some embodiments, when the second absorbent assembly 122 is at least partially held in the second retaining cavity 622, the second absorbent assembly 122 is held against the wall defining the second retaining cavity 622 to prevent leakage of the aerosol-generating matrix along the wall defining the second retaining cavity 622. The second absorbent assembly 622 may be interference-fitted into the second retaining cavity 622. Of course, in other embodiments, the size of the second absorbent assembly 122 may be approximately the same as the size of the second retaining cavity 622. After absorbing the aerosol-generating matrix, the second absorbent assembly 122 expands, thereby compressing the wall defining the second retaining cavity 622 to achieve a seal and prevent leakage of the second absorbent assembly 122 along the wall defining the second retaining cavity 622.

[0338] In some embodiments, the first base 64 extends laterally, and the opposite ends of the first base 64 in the lateral direction are correspondingly connected to the first sub-support 61 and the second sub-support 62.

[0339] In some embodiments, the first sub-support 61 has a first receiving cavity 615 for receiving at least a portion of the first base 64, and the first sub-support 61 includes a first support portion 616, the first support portion 616 including a wall defining a partial boundary of the first holding cavity 612, the first support portion 616 being located between the first receiving cavity 612 and the first holding cavity 615, such that when the first base 64 is at least partially held in the first receiving cavity 615, the first base 64 is spaced apart from the first liquid absorption assembly 121, which helps to prevent the aerosol generation matrix from leaking out of the support assembly 6.

[0340] Furthermore, the first support portion 616 is used to support the first liquid suction assembly 121 in the longitudinal direction, thereby causing the first base 64 and the first liquid suction assembly 121 to be spaced apart in the longitudinal direction. The first support portion 616 includes a wall defining a portion of the boundary of the first receiving cavity 615, which can contact the mounting surface 641 of the first base 64.

[0341] In some embodiments, the first sub-support 61 further includes a third support portion 617, which is longitudinally spaced from the first support portion 616. When the first base 64 is connected to the first sub-support 61, at least a portion of the first base 64 is disposed between the first support portion 616 and the third support portion 617, and the third support portion 617 can support the first base 64 longitudinally. In other words, at least a portion of the first receiving cavity 615 is disposed between the first support portion 616 and the third support portion 617. Furthermore, by using the longitudinally spaced first support portion 616 and the third support portion 617, at least a portion of the first base 64 must be laterally assembled into the first receiving cavity 615, and after the second sub-support 62 is connected, the third support portion 617 can also prevent the first base 64 from detaching longitudinally.

[0342] In some embodiments, the second support 63 has a second receiving cavity 625 for receiving at least a portion of the first base 64, and the second sub-support 62 includes a second support portion 626, which includes a wall defining a partial boundary of the second holding cavity 622. The second support portion 626 is located between the second receiving cavity 625 and the second holding cavity 622, such that when the first base 64 is at least partially held in the second receiving cavity 625, the first base 64 is spaced apart from the second liquid absorption element 122, which helps to prevent the aerosol generation matrix from leaking out of the support assembly 6.

[0343] Furthermore, the second support portion 626 is used to support the second liquid-absorbing assembly 122 in the longitudinal direction, thereby causing the first base 64 and the second liquid-absorbing assembly 122 to be spaced apart in the longitudinal direction. The second support portion 626 includes a wall defining a portion of the boundary of the second receiving cavity 625, which can contact the mounting surface 641 of the first base 64.

[0344] In some embodiments, the second sub-support 62 further includes a fourth support portion 627, which is longitudinally spaced from the second support portion 626. When the first base 64 is connected to the second sub-support 62, at least a portion of the first base 64 is disposed between the second support portion 626 and the fourth support portion 627, and the fourth support portion 627 can support the first base 64 longitudinally. In other words, at least a portion of the second receiving cavity 625 is disposed between the second support portion 626 and the fourth support portion 627. Furthermore, by using the longitudinally spaced second support portion 626 and the fourth support portion 627, at least a portion of the first base 64 must be laterally assembled into the second receiving cavity 625, and after the first sub-support 61 is connected, the fourth support portion 627 can also prevent the first base 64 from detaching longitudinally.

[0345] In some embodiments, the first sub-bracket 61 and the second sub-bracket 62 are snap-fitted together so that they can remain in a combined state after being combined.

[0346] For example, the first sub-support 61 is provided with a first connecting arm 618 extending laterally and a first fastening part 619 provided on the first connecting arm 618, while the second sub-support 62 is provided with a first fastening engagement part (not shown). When the first sub-support 61 and the second sub-support 62 are connected, the first connecting arm 618 guides the first sub-support 61 and the second sub-support 62 to combine with each other laterally until the first fastening part 619 and the first fastening engagement part are engaged. One of the first fastening part 619 and the first fastening engagement part includes a protrusion, and the other includes a groove. Preferably, the groove is a blind groove. By fitting the protrusion into the groove, the first fastening part 619 and the first fastening engagement part are engaged, thus preventing the first sub-support 61 and the second sub-support 62 from separating laterally.

[0347] As an example, the second sub-support 62 is provided with a second connecting arm 628 extending laterally and a second fastening portion 629 provided on the second connecting arm 628, while the first sub-support 61 is provided with a second fastening engagement portion (not shown). When the first sub-support 61 and the second sub-support 62 are connected, the second connecting arm 628 guides the first sub-support 61 and the second sub-support 62 to engage laterally until the second fastening portion 629 and the second fastening engagement portion are engaged. One of the second fastening portion 629 and the second fastening engagement portion includes a protrusion, and the other includes a groove. Preferably, the groove is a blind groove. By fitting the protrusion into the groove, the second fastening portion 629 and the second fastening engagement portion are engaged, thus preventing the first sub-support 61 and the second sub-support 62 from separating laterally. Furthermore, the second fastening part 629 and the second fastening engagement part are located on opposite sides of the bracket assembly 6, and the first connecting arm 618 and the second connecting arm 628 are located on opposite sides of the bracket assembly 6. Similarly, the first fastening engagement part and the second fastening engagement part are located on opposite sides of the bracket assembly 6.

[0348] As an example, the first sub-support 61 is further provided with a third connecting arm 618' extending laterally and a third fastening part 619' provided on the third connecting arm 618', while the second sub-support 62 is provided with a third fastening engagement part 630'. When the first sub-support 61 and the second sub-support 62 are connected, the third connecting arm 618' guides the first sub-support 61 and the second sub-support 62 to combine with each other laterally until the third fastening part 619' and the third fastening engagement part 630' are snapped together. One of the third fastening part 619' and the third fastening engagement part 630' includes a protrusion, and the other includes a groove. Preferably, the groove is a blind groove. By fitting the protrusion into the groove, the third fastening part 619' and the third fastening engagement part 630' are snapped together, thus preventing the first sub-support 61 and the second sub-support 62 from separating laterally. Furthermore, the third fastening part 619' and the third fastening engagement part 630' are disposed on opposite sides of the first sub-support 61, and the first connecting arm 618 and the third connecting arm 618' are disposed on opposite sides of the first sub-support 61. Similarly, the first fastening engagement part and the third fastening engagement part 630' are disposed on opposite sides of the second support.

[0349] As an example, the second sub-support 62 is further provided with a fourth connecting arm 628' extending laterally and a fourth fastening part 629' provided on the fourth connecting arm 628', while the first sub-support 61 is provided with a fourth fastening engagement part. When the first sub-support 61 and the second sub-support 62 are connected, the fourth connecting arm 628' guides the first sub-support 61 and the second sub-support 62 to combine with each other laterally until the fourth fastening part 629' and the fourth fastening engagement part are engaged. One of the fourth fastening part 629' and the fourth fastening engagement part includes a protrusion, and the other includes a groove. Preferably, the groove is a blind groove. By fitting the protrusion into the groove, the fourth fastening part 629' and the fourth fastening engagement part are engaged, thus preventing the first sub-support 61 and the second sub-support 62 from separating laterally. Furthermore, the second fastening part 629 and the fourth fastening part 629' are disposed on opposite sides of the second sub-support 62, and the second connecting arm 628 and the fourth connecting arm 628' are disposed on opposite sides of the second sub-support 62. Similarly, the second fastening engagement part and the fourth fastening engagement part are disposed on opposite sides of the first sub-support 61.

[0350] As an example, the first sub-support 61 is also provided with a first connecting arm 618 and a third connecting arm 618' extending laterally. The first connecting arm 618 and the third connecting arm 618' are located on opposite sides of the first sub-support 61, and the first connecting arm 618 and the third connecting arm 618' are located at different longitudinal heights of the first support. The first connecting arm 618 is provided with a first fastening part 619, and the third connecting arm 618' is provided with a third fastening part 619'. The first sub-support 61 also has a second fastening engagement part (not shown) adjacent to the first connecting arm 618 and a fourth fastening engagement part (not shown) adjacent to the third connecting arm 619'.

[0351] Meanwhile, the second sub-support 62 is also provided with a second connecting arm 628 and a fourth connecting arm 628' extending laterally. The second connecting arm 628 and the fourth connecting arm 628' are located on opposite sides of the second sub-support 62, and the second connecting arm 628 and the fourth connecting arm 628' are located at different longitudinal heights of the second sub-support 62. The second connecting arm 628 is provided with a second fastening part 629, and the fourth connecting arm 628' is provided with a fourth fastening part 629'. The second sub-support 62 also has a first fastening engagement part (not shown) adjacent to the second connecting arm 628 and a third fastening engagement part 630' adjacent to the fourth connecting arm 628'.

[0352] When the first sub-support 61 and the second sub-support 62 are connected, the third connecting arm 618' and the second connecting arm 628 can be located on the same side and are staggered. The third fastening part 619' is snapped into the third fastening engagement part, and the second fastening part 619' is snapped into the second fastening engagement part. The first connecting arm 618 and the fourth connecting arm 628' are located on the same side and are staggered. The first fastening part 619' is snapped into the first fastening engagement part.

[0353] Thus, when the first sub-support 61 and the second sub-support 62 are connected, the first sub-support 61 is connected by the first connecting arm 618 and the third connecting arm 618', and the second sub-support 62 is connected by the second connecting arm 628 and the fourth connecting arm 628', so that the first sub-support 61 and the second sub-support 62 hug each other.

[0354] As an example, referring to FIG33, the second sub-support 62 includes a mating groove a, and the first sub-support 61 includes a mating portion b. When the first sub-support 61 and the second sub-support 62 are connected, at least a portion of the mating portion b is located in the mating groove a. Further, the mating groove a has an opening providing entry for the mating portion b, the opening being laterally disposed such that the first sub-support 61 and the second sub-support 62 are laterally connected. Further still, the second sub-support 62 is also provided with a laterally extending third connecting arm 628 and a fourth connecting arm 628', which are disposed on opposite sides of the second sub-support 62. In this embodiment, the third connecting arm 628 and the fourth connecting arm 628' may be disposed at the same longitudinal height of the second sub-support 62. The third connecting arm 628 is provided with a second fastening portion 629, and the fourth connecting arm 628' is provided with a fourth fastening portion 629'; the first support 62 is provided with a second fastening engagement portion 620 and a fourth fastening engagement portion. When the first sub-bracket 61 and the second sub-bracket 62 are connected, at least a portion of the mating part b is located in the mating groove a, and the second fastening part is snapped into connection with the second fastening engagement part 620, and the third fastening part 629' is snapped into connection with the fourth fastening engagement part.

[0355] It should be noted that the connection between the first sub-support 61 and the second sub-support 62 via snap-fit ​​is optional, not mandatory. For example, the first sub-support 61 and the second sub-support 62 can also be connected by welding and / or screws to maintain their combined state. Furthermore, the first sub-support 61 and the second sub-support 62 can be connected by a binding or clamping member, wherein the clamping member includes an elastic clamping sleeve, or the clamping member includes a shell capable of simultaneously covering at least a portion of the first sub-support 61 and the second sub-support 62, and capable of inwardly pressing the first sub-support 61 and the second sub-support 62 so that the first sub-support 61 and the second sub-support 62 are tightly pressed together.

[0356] It should be noted that combining the first sub-support 61 and the second sub-support 62 in the transverse direction is optional, not mandatory. For example, in other embodiments, the first sub-support 61 and the second sub-support 62 can also be combined in the longitudinal direction. After the two are combined, the first sub-support 61 and the second sub-support 62 are mainly arranged in the transverse direction.

[0357] In some embodiments, referring to FIG17, at least one of the first inlet 611 and the second inlet 621 is disposed toward the proximal end 51. In other words, the first inlet 611 and / or the second inlet 621 are opened longitudinally, so that at least a portion of the aerosol generating matrix in the storage cavity 21 can enter the first inlet 611 and / or the second inlet 621 longitudinally. Compared with both the first inlet 611 and the second inlet 612 being opened laterally, this helps to reduce the space occupied by the support assembly 6 in the storage cavity 21, which is beneficial to increasing the volume of the storage cavity 21, allowing the atomizer 200 to store more aerosol generating matrix, thereby helping to improve the user experience. Furthermore, the support assembly 6 has an end disposed toward the proximal end 51, which defines a portion of the boundary of the storage cavity 21, and at least one of the first inlet 611 and the second inlet 621 is located on this end. Furthermore, the first sub-support 61 includes a first top wall c disposed toward the proximal end 51, and a first inlet 611 is formed on the first top wall c, which can define a portion of the boundary of the storage cavity 21; and / or, the second sub-support 62 includes a second top wall d disposed toward the proximal end 51, and a second inlet 621 is formed on the second top wall d, which can define a portion of the boundary of the storage cavity 21.

[0358] In some embodiments, the first sub-support 61 includes a first top wall c disposed toward the proximal end 51 and a first side wall e extending from the first top wall c in a direction away from the proximal end 51. A first inlet 611 is formed on the first top wall c. The support assembly 6 also includes a first seal 66, at least partially disposed between the first side wall e and the housing 2, to provide a seal between the first side wall e and the housing 2, thereby preventing leakage of the aerosol-generating matrix from the housing 2 and the first sub-support 61. The first seal 66 may be made of silicone.

[0359] As an example, the first seal 66 has a first annular portion surrounding the first sub-support 61, with a portion of the first annular portion disposed between the first sub-support 61 and the second sub-support 62. The first annular portion can resiliently abut against the second sub-support 62 or the second seal 67, thereby providing a seal between the first sub-support 61 and the second sub-support 62. Alternatively, the first annular portion can be spaced apart from the second sub-support 62. A portion of the first annular portion can be disposed between the first sub-support 61 and the housing 2, thereby providing a seal between the first sub-support 61 and the housing 2.

[0360] If the first inlet 611 is positioned facing the proximal end 51 or is located on the first top wall c, the first annular portion can be positioned adjacent to the first top wall c. When the first annular portion is positioned adjacent to the first top wall c, the sealing requirements between the first sub-support 61 and the second sub-support 62 can be reduced in the interval between the first annular portion and the distal end 52.

[0361] As an example, a portion of the air duct 3 is surrounded by a first sub-support 61 and a second sub-support 62, and a portion of the first seal 66 is disposed between the first sidewall e and the air duct 3 to provide a seal between the first sidewall e and the air duct 3, thereby preventing the aerosol generating matrix from leaking from between the air duct 3 and the first support 6.

[0362] As an example, referring to FIG17, the atomizer 200 further includes a partition 7 disposed within the housing 2 and dividing the storage chamber 21 into a first storage chamber 211 and a second storage chamber 212. A first inlet 611 is used to guide the aerosol generating matrix in the first storage chamber 211 to the atomizing assembly 1, and a second inlet 621 is used to guide the aerosol generating matrix in the second storage chamber 212 to the atomizing assembly 1. A first seal 66 is partially disposed between the first sidewall e and the partition 7 to provide a seal between the first sidewall e and the partition 7, thereby preventing leakage of the aerosol generating matrix from the air guide tube 3 and the first support 6.

[0363] As an example, the first seal 66 and the first sub-support 61 are integrally formed by in-mold injection molding. In particular, when the first seal 66 includes a first annular portion surrounding the first sub-support 61 and the first sub-support 61 has an irregular peripheral shape, in-mold injection molding helps to bond the first seal 66 to the first support, making the first seal 66 fit snugly with the first sub-support 61.

[0364] In some embodiments, the second sub-support 62 includes a second top wall d disposed toward the proximal end 51 and a second side wall f extending from the second top wall d in a direction away from the proximal end 51. A second inlet 621 is formed on the second top wall d. The support assembly 6 also includes a second seal 67, at least partially disposed between the second side wall f and the housing 2, to provide a seal between the second side wall f and the housing 2, thereby preventing leakage of the aerosol-generating matrix from the housing 2 and the second sub-support 62. The second seal 67 may be made of silicone.

[0365] As an example, the second seal 67 has a second annular portion surrounding the second sub-support 62, with a portion of the second annular portion disposed between the first sub-support 61 and the second sub-support 62. The second annular portion can resiliently abut against the first sub-support 61 or the first seal 66, thereby providing a seal between the first sub-support 61 and the second sub-support 62. Alternatively, the second annular portion can be spaced apart from the first sub-support 61. A portion of the second annular portion can be disposed between the second sub-support 62 and the housing 2, thereby providing a seal between the second sub-support 62 and the housing 2.

[0366] As an example, a portion of the air duct 3 is surrounded by a first sub-support 61 and a second sub-support 62, and a portion of the second seal 67 is disposed between the second sidewall f and the air duct 3 to provide a seal between the second sidewall f and the air duct 3, thereby preventing leakage of the aerosol generating matrix from between the air duct 3 and the second sub-support 62.

[0367] As an example, the second seal 67 is partially disposed between the second sidewall f and the partition 7 to provide a seal between the second sidewall f and the partition 7, thereby preventing the aerosol generation matrix from leaking from the gas duct 3 and the second sub-support 62.

[0368] Furthermore, the partition 7 is partially fitted between the first sub-support 61 and the second sub-support 62, and the opposite sides of the partition 7 elastically abut against the first seal 66 and the second seal 67, respectively.

[0369] As an example, the second seal 67 and the second sub-support 62 are integrally formed by in-mold injection molding. In particular, when the second seal 67 includes a second annular portion surrounding the second sub-support 62 and the second sub-support 62 has an irregular peripheral shape, in-mold injection molding helps to bond the second seal 67 to the second sub-support 62, ensuring a close fit between the second seal 67 and the second sub-support 62.

[0370] The first seal 66 is independent of the second seal 67, and the first seal 66 and the second seal 67 can be molded or manufactured separately. The first seal 66 and the second seal 67 can be made of the same material. The first seal 66 and the second seal 67 can have the same shape or structure.

[0371] It should be noted that the partition 7 is optional rather than mandatory. In the embodiment shown in FIG31, the first inlet 611 and the second inlet 621 are connected to the same storage cavity.

[0372] In some embodiments, referring to FIG31, a first inlet 611 is provided on a first top wall c, a second inlet 621 is provided on a second top wall d, and the bracket assembly 6 further includes a seal 68. The annular portion of the seal 68 is disposed around the first sub-bracket 61 and the second sub-bracket 62, and provides a seal between the first side wall e and the housing 2, and between the second side wall f and the housing 2. At the same time, the annular portion of the seal 68 can also tightly clamp the first sub-bracket 61 and the second sub-bracket 62 together, so that the first sub-bracket 61 and the second sub-bracket 62 remain in a combined state.

[0373] As an example, referring to Figure 33, a retaining groove g is provided on the first sub-support 61, a portion of the air duct 3 is located in the retaining groove g, and the seal 68 provides a seal between the first sub-support 61 and the air duct 3.

[0374] The sealing element 68 may include a first part and a second part having an annular portion. The first and second parts can be integrally formed and thus interconnected. When the first and second parts are integrally formed, a first guide hole 681 is formed on the first part corresponding to the first inlet 611, so that the aerosol generating matrix in the storage cavity 211 can flow into the first inlet 611. The area of ​​the first guide hole 681 may be larger than the area of ​​the first inlet 611, so that a portion of the first top wall c is exposed through the first guide hole 681. Furthermore, a second guide hole 682 is formed on the first part corresponding to the second inlet 621, so that the aerosol generating matrix in the storage cavity 211 can flow into the second inlet 621. The area of ​​the second guide hole 682 may be larger than the area of ​​the second inlet 621, so that a portion of the second top wall d is exposed through the second guide hole 682.

[0375] Of course, the first part and the second part can also be independent of each other.

[0376] As an example, the first sub-support 61 and the second sub-support 62 together form a retaining groove g, a portion of the air duct 3 is located in the retaining groove g, the first seal 66 provides a seal between the first sub-support 61 and the air duct 3, and the second seal 67 provides a seal between the second sub-support 62 and the air duct 3.

[0377] In some embodiments, referring to Figures 17 and 31, the first sub-support 61 is provided with a first outlet 614 communicating with the atomizing component 1 and a first channel h communicating with the first inlet 611 and the first outlet 614. After the aerosol generating matrix flows into the first inlet 611, it needs to flow through the first channel h to the first outlet 614 and finally to the atomizing component 1.

[0378] As an example, the cross-sectional area of ​​the first inlet 611 is larger than the cross-sectional area of ​​the first outlet 614. Therefore, when the first inlet 611 is positioned towards the proximal end 51, or when the first inlet 611 is opened longitudinally, the first channel h can receive and store a portion of the aerosol generation matrix. Thus, when the user inhales into the atomizer 200, causing the atomizer 200 to tilt, the first channel h can lock in a portion of the aerosol generation matrix, allowing the first liquid absorption assembly 121 to maintain the acquisition of the aerosol generation matrix. This helps ensure that the atomizing assembly 1 has sufficient aerosol generation matrix for atomization and helps prevent the atomizing assembly 1 from dry-burning.

[0379] As an example, the cross-sectional area of ​​the first outlet 614 near the atomizing component 1 or near the holding cavity of the atomizing component 1 is different from the cross-sectional area of ​​the first outlet 614 away from the atomizing component 1 or near the first channel h, so as to adjust the velocity of the aerosol generating matrix flowing from the first channel h to the atomizing component 1. Furthermore, the cross-sectional area of ​​the first outlet 614 near the atomizing component 1 or near the holding cavity of the atomizing component 1 is larger than the cross-sectional area of ​​the first outlet 614 away from the atomizing component 1 or near the first channel h, so as to reduce the velocity of the aerosol generating matrix flowing from the first channel h to the atomizing component 1 and prevent leakage of the aerosol generating matrix due to excessive flow rate.

[0380] As an example, the first outlet 614 has multiple outlets to ensure that a sufficient aerosol generation matrix is ​​directed to the atomizing component 1, thereby preventing the atomizing component 1 from burning dry.

[0381] As an example, a strip groove h1 is provided on the wall of the first channel h, which can extend to the first inlet 611 to prevent air bubbles from adhering to the wall of the first channel h and the first inlet 611, thus helping to prevent the first channel h and the first inlet 611 from being blocked by air bubbles.

[0382] As an example, the cross-sectional area of ​​the first inlet 611 is larger than that of the first channel h, so as to prevent the bubbles generated in the first channel h from accumulating and increasing in size at the first inlet 611 and blocking the first inlet 611, ensuring that the aerosol generation matrix can smoothly enter the first channel h, which helps to prevent the atomizing component 1 from burning dry.

[0383] As an example, the cross-sectional area of ​​the first inlet 611 is greater than 1 / 4 of the cross-sectional area of ​​the storage cavity 21. Furthermore, the cross-sectional area of ​​the first inlet 611 is greater than 1 / 2 of the cross-sectional area of ​​the first storage cavity 211. This is to prevent the first inlet 611 from being blocked by air bubbles, ensuring that the aerosol generation matrix can smoothly enter the first outlet 614.

[0384] As an example, the opening directions of the first inlet 611 and the first outlet 614 are intersecting or perpendicular, which helps to reduce the size of the bracket assembly 6.

[0385] As an example, the edge of the first inlet 611 is provided with a recessed structure to prevent air bubbles from adhering to the first inlet 611, thus helping to prevent the first inlet 611 from being blocked by air bubbles.

[0386] As an example, a first groove i extending from the first outlet 614 is provided on the third sidewall 613 where the first outlet 614 is located. The first groove i is positioned facing the atomizing assembly 1. The first groove i is used to guide the aerosol generating matrix discharged from the first outlet 614 to a wider area, so that a larger area of ​​the first liquid absorption assembly 121 can absorb the aerosol generating matrix discharged from the first outlet 614. This helps to ensure that the aerosol generating matrix is ​​evenly distributed in the first liquid absorption assembly 121 and helps to prevent local areas of the first liquid absorption assembly 121 from being scorched by the first heating part 111. Preferably, the first groove i extends longitudinally.

[0387] As an example, the atomizing assembly 1 includes a first end portion disposed away from the proximal end 51 and a second end portion disposed towards the proximal end 51, with a first outlet 614 disposed adjacent to the first end portion. Further, the opening of the first outlet 614 towards the first liquid-absorbing assembly 121 is disposed adjacent to the first end portion of the first liquid-absorbing assembly 121, and the first heating element 111 is mainly located between the first and second ends. This allows the first liquid-absorbing assembly 121 to conduct the aerosol-generating matrix from the first end portion towards the second end portion, enabling the aerosol-generating matrix to be conducted against gravity, thus helping to prevent leakage of the aerosol-generating matrix. Moreover, when the user inhales into the atomizer 200, causing the atomizer 200 to tilt, the first outlet 614 can be immersed in the aerosol-generating matrix, allowing the first liquid-absorbing assembly 121 to maintain the acquisition of the aerosol-generating matrix. This helps ensure that the atomizing assembly 1 has a sufficient amount of aerosol-generating matrix for atomization and helps prevent the atomizing assembly 1 from dry-burning.

[0388] In some embodiments, the second sub-support 62 is provided with a second outlet 624 that connects to the atomizing component 1 and a second channel j that connects the second inlet 621 and the second outlet 624. After the aerosol generating matrix flows into the second inlet 621, it needs to flow through the second channel j to the second outlet 624 and finally to the atomizing component 1.

[0389] As an example, the cross-sectional area of ​​the second inlet 621 is larger than that of the second outlet 624. Therefore, when the second inlet 621 is positioned towards the proximal end 51, or when the second inlet 621 is opened longitudinally, the second channel j can receive and store a portion of the aerosol generation matrix. Thus, when the user inhales into the atomizer 200, causing the atomizer 200 to tilt, the second channel j can lock in a portion of the aerosol generation matrix, allowing the second liquid absorption assembly 122 to maintain the acquisition of the aerosol generation matrix. This helps ensure that the atomizing assembly 1 has sufficient aerosol generation matrix for atomization and helps prevent the atomizing assembly 1 from dry-burning.

[0390] As an example, the cross-sectional area of ​​the second outlet 624 near the atomizing component 1 or near the holding cavity of the atomizing component 1 is different from the cross-sectional area of ​​the second outlet 624 away from the atomizing component 1 or near the second channel j, so as to regulate the velocity of the aerosol generating matrix flowing from the second channel j to the atomizing component 1. Furthermore, the cross-sectional area of ​​the second outlet 624 near the atomizing component 1 or near the holding cavity of the atomizing component 1 is larger than the cross-sectional area of ​​the second outlet 624 away from the atomizing component 1 or near the second channel j, so as to reduce the velocity of the aerosol generating matrix flowing from the second channel j to the atomizing component 1 and prevent leakage of the aerosol generating matrix due to excessive flow rate.

[0391] As an example, the second outlet 624 has multiple outlets to ensure that sufficient aerosol generation matrix is ​​directed to the atomizing component 1, thereby preventing the atomizing component 1 from burning dry.

[0392] As an example, a strip groove h1 is provided on the wall of the second channel j, which can extend to the second inlet 621 to prevent air bubbles from adhering to the wall of the second channel j and the second inlet 621, thus helping to prevent the second channel j and the second inlet 621 from being blocked by air bubbles.

[0393] As an example, the cross-sectional area of ​​the second inlet 621 is larger than that of the second channel j to prevent bubbles generated in the second channel j from accumulating and increasing in size at the second inlet 621 and blocking the second inlet 621, ensuring that the aerosol generation matrix can smoothly enter the second channel j, which helps to prevent the atomizing component 1 from burning dry.

[0394] As an example, the cross-sectional area of ​​the second inlet 621 is greater than 1 / 4 of the cross-sectional area of ​​the storage cavity 21. Furthermore, the cross-sectional area of ​​the second inlet 621 is greater than 1 / 2 of the cross-sectional area of ​​the second storage cavity 212. This is to prevent the second inlet 621 from being blocked by air bubbles, ensuring that the aerosol generation matrix can smoothly enter the second outlet 624.

[0395] As an example, the opening directions of the second inlet 621 and the second outlet 624 are intersecting or perpendicular, which helps to reduce the size of the bracket assembly 6.

[0396] As an example, the edge of the second inlet 621 is provided with a recessed structure to prevent air bubbles from adhering to the second inlet 621, thus helping to prevent the second inlet 621 from being blocked by air bubbles.

[0397] As an example, a second groove k extending from the second outlet 624 is provided on the fourth sidewall 623 where the second outlet 624 is located. The second groove k is positioned towards the atomizing assembly 1. The second groove k is used to guide the aerosol generating matrix discharged from the second outlet 624 to a wider area, so that a larger area of ​​the second liquid absorption assembly 122 can absorb the aerosol generating matrix discharged from the second outlet 624. This helps to ensure that the aerosol generating matrix is ​​evenly distributed in the second liquid absorption assembly 122 and helps to prevent local areas of the second liquid absorption assembly 122 from being scorched by the second heating part 112. Preferably, the second groove k extends longitudinally.

[0398] As an example, the atomizing assembly 1 includes a first end facing away from the proximal end 51 and a second end facing the proximal end 51, with a second outlet 624 disposed adjacent to the first end. Further, the opening of the second outlet 624 facing the second liquid-absorbing assembly 122 is disposed adjacent to the first end of the second liquid-absorbing assembly 122, and the second heating part 112 is mainly located between the first and second ends. This allows the second liquid-absorbing assembly 122 to conduct the aerosol-generating matrix from the first end to the second end, enabling the aerosol-generating matrix to be conducted against gravity, thus helping to prevent leakage of the aerosol-generating matrix. Moreover, when the user inhales into the atomizer 200, causing the atomizer 200 to tilt, the second outlet 624 can be immersed in the aerosol-generating matrix, allowing the second liquid-absorbing assembly 122 to maintain the acquisition of the aerosol-generating matrix. This helps ensure that the atomizing assembly 1 has a sufficient amount of aerosol-generating matrix for atomization and helps prevent the atomizing assembly 1 from dry-burning.

[0399] The second channel j is set independently of the first channel h.

[0400] In some embodiments, the support assembly 6 is disposed inside the housing 2 and forms a sealing connection with the inner wall of the housing 2. Furthermore, the atomizer 200 also includes a second base 8, which is connected to the housing 2 and supports the support assembly 6, thereby keeping the support assembly 6 inside the housing 2.

[0401] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
