Description

Technical Field

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

[0002] An aerosol generating device is a device capable of atomizing an aerosol generating matrix to generate aerosols. An exemplary aerosol generating device exists, comprising a support and a heating element. The heating element includes two heating sections and a connecting section connecting the two heating sections. The heating element is moved by clamping the end of the connecting section facing the outlet of the aerosol generating device, aligning the heating element with a corresponding portion of the support. Then, the end of the connecting section facing the outlet is pressed to form a stable connection between the heating element and the support. Finally, the connecting section and the two heating sections are both erected on the support.

[0003] However, the heating element is made of a conductive sheet, which makes the connection part less rigid. As a result, the connection part is extremely easy to bend and deform during the process of pressing the connection part to join the heating element and the bracket, resulting in high rework rate and low production efficiency. Summary of the Invention

[0075] Please refer to Figure 1 This application provides an aerosol generating device, which includes an atomizer 200 and a power supply component 100. The power supply component 100 can be used in conjunction with the atomizer 200 and can provide electrical power to the atomizer 200 so that the atomizer 200 atomizes the aerosol generating matrix to generate aerosol.

[0076] In some embodiments, the aerosol-generating matrix includes a liquid matrix that is liquid at room temperature. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components. The liquid matrix may also contain a liquid containing non-tobacco substances. The liquid matrix may contain water, 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 flavoring components, etc. Flavorings may contain ingredients that can provide the user with various aromas or flavors.

[0077] In some embodiments, the aerosol-generating matrix includes a solid matrix that is solid at room temperature. The solid matrix may comprise a solid containing tobacco-containing substances, including volatile tobacco aroma components. The solid matrix may also comprise a solid containing non-tobacco substances.

[0078] In other embodiments, the aerosol generating matrix also includes a paste-like matrix that is in the form of a paste at room temperature.

[0079] In some embodiments, the atomizer 200 includes an atomizing core 1 for atomizing an aerosol generating matrix to produce an aerosol.

[0080] The atomizing core 1 may include a liquid absorption assembly 12 and a heating element 11. The liquid absorption assembly 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 assembly 12 can be atomized to generate aerosol under the heat released by the heating element 11.

[0081] The liquid absorption component 12 may include a porous body. The porous body may be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body may also be a porous ceramic or a porous metal; this application does not limit the structure and composition of the porous body.

[0082] 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 core 1 is in fluid communication with the storage cavity 21, so that the atomizing core 1 can atomize the aerosol generation matrix contained in the storage cavity 21 to generate an aerosol.

[0083] In some embodiments, the atomizer 200 further includes an air guide tube 3, which guides the aerosol generated by the atomizing aerosol matrix from the atomizing core 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 core 1 may be disposed inside the housing 2.

[0084] 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.

[0085] In some embodiments, the atomizer 200 further includes a liquid reservoir element (not shown) having a large number of pores capable of adsorbing a large amount of liquid matrix. The liquid reservoir element is disposed in a storage cavity, and at least partially retains the liquid matrix stored in the storage cavity within the liquid reservoir element, thereby preventing leakage of the aerosol-generating matrix from the storage cavity. The liquid reservoir element 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.

[0086] In some embodiments, reference may be made to Figure 1 The aerosol generating device also includes a nozzle 4, at least a portion of which can be held in the mouth by a user, the nozzle 4 being used to introduce aerosols into the user's oral cavity.

[0087] Furthermore, the atomizer 200 includes a mouthpiece 4, or the mouthpiece 4 of an aerosol generating device is disposed on the atomizer 200, thereby the mouthpiece 4 includes the aforementioned air outlet 41. Even further, the mouthpiece 4 is integrally formed with the outer shell 2.

[0088] In some embodiments, reference may be made to Figure 2The atomizer 200 also includes a support assembly 6, at least a portion of the atomizing core 1 is disposed in the support assembly 6, and the support assembly 6 has a first inlet 611, which can guide at least a portion of the aerosol generation matrix in the storage chamber 21 to the atomizing core 1 for atomization.

[0089] 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.

[0090] 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.

[0091] 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 atomizing core 1 is increased, thereby improving the atomization efficiency of the atomizer 200 and increasing the amount of aerosol.

[0092] 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.

[0093] 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 core 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.

[0094] 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.

[0095] In some embodiments, reference may be made to Figure 6 The first heating part 111 and the second heating part 112 are not coplanar, so that the aerosol is more concentrated, which can reduce the loss of aerosol in the atomizer 200 and also help to reduce the size of the atomizing chamber 63.

[0096] In some embodiments, reference may be made to Figure 6 , Figure 8 , Figure 9 and Figure 13 The heating element 11 also includes a connecting portion 113 / 113', which is located between the first heating portion 111 and the second heating portion 112, and is electrically connected to the first heating portion 111 and the second heating portion 112. The connecting portion 113 / 113' can support the first heating portion 111 and the second heating portion 112 to a certain extent, maintaining a distance and a certain rigidity between them. Based on this, the connecting portion 113 / 113' can have greater rigidity. The first heating portion 111 and the second heating portion 112 can be connected in series through the connecting portion 113 / 113'.

[0097] In some embodiments, reference may be made to Figure 6 , Figure 8 , Figure 9 and Figure 13 At least one of the first heating part 111 and the second heating part 112 is not coplanar with the connecting part 113 / 113'. Preferably, the first heating part 111, the second heating part 112, and the connecting part 113 / 113' are not coplanar with each other. More preferably, the first heating part 111 and the second heating part 112 extend on the same side of the connecting part 113 / 113'.

[0098] In such Figure 9 and Figure 13 In the illustrated embodiment, 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, thereby making the heating element 11 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.

[0099] In some embodiments, reference may be made to Figure 2The support assembly 6 also 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 part 111 and the second heating part 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.

[0100] In some embodiments, reference may be made to Figure 2 and Figure 16 The first base 64 has a vent 643 that connects to the atomizing chamber 63. Along the airflow direction, the vent 643 is located upstream of the atomizing chamber 63 and can guide the airflow into the atomizing chamber 63.

[0101] In some embodiments, reference may be made to Figure 6 The first heating part 111 and the second heating part 112 are vertically mounted on the first base 64.

[0102] For example, the first heating element 111 and / or the second heating element 112 may be arranged perpendicular to the mounting surface 641.

[0103] For example, the first heating part 111 can be inclined relative to the mounting surface 641, so that the first heating part 111 is inclined toward the vent 643. Therefore, at least part of the airflow entering the atomization chamber 63 through the vent 643 can be blown obliquely toward the first heating part 111, so that the airflow can be more concentrated on the surface of the first heating part 111 and the volatile substances generated by the aerosol generation matrix can be more fully combined with the airflow, thereby helping to form a larger amount of aerosol.

[0104] For example, the second heating part 112 can be inclined relative to the mounting surface 641, so that the second heating part 112 is inclined toward the vent 643. Therefore, at least part of the airflow entering the atomization chamber 63 through the vent 643 can be blown obliquely toward the second heating part 112, so that the airflow can be more concentrated on the surface of the second heating part 112 and the volatile substances generated by the aerosol generation matrix can be more fully combined with the airflow, thereby helping to form a larger amount of aerosol.

[0105] In some embodiments, the connecting portion 113 / 113′ is connected to the first base 64.

[0106] As an example, you can refer to Figure 6The connecting portion 113 is located on the same side as the mounting surface 641, and the connecting portion 113 is vertically mounted on the first base 6. Furthermore, the first heating portion 111 extends laterally from one side of the connecting portion 113 in a direction away from the connecting portion 113, and the second heating portion 112 extends laterally from the other side of the connecting portion 113 in a direction away from the connecting portion 113.

[0107] As an example, you can refer to Figure 12 The connecting portion 113' is located on the same side as the mounting surface 643, and the connecting portion 113' is horizontally disposed on the first base 64, thereby the connecting portion 113' is supported longitudinally by the first base 64. Furthermore, the connecting portion 113' is arranged parallel to the mounting surface 641. Of course, in other embodiments, at least a portion of the connecting portion 113' may be embedded inside the first base 64. Alternatively, in other embodiments, the connecting portion 113' may be located on the same side as the base surface 642, thereby placing the first heating portion 111 and / or the second heating portion 112 on opposite sides of the first base 64.

[0108] In some embodiments (not shown), the connecting portion is horizontally disposed and spaced longitudinally from the first base, so that the atomizing chamber can be located between the connecting portion and the first base.

[0109] When the connecting part 113 is vertically arranged, the connecting part 133 can be approximately trapezoidal. The first heating part 111 and the second heating part 112 are respectively connected to the waist of the trapezoid, so that at least part of the airflow entering the atomizing chamber 63 through the vent 643 can be blown obliquely toward the first heating part 111 and / or the second heating part 112.

[0110] When the connecting part 113′ is horizontally arranged and connected to the first base 64, the angle between the first heating part 111 and / or the second heating part 112 and the connecting part 113′ can be an acute angle, so that at least part of the airflow entering the atomizing chamber 63 through the vent 643 can be blown obliquely toward the first heating part 111 and / or the second heating part 112.

[0111] When the connecting part 113′ is horizontally arranged and the connecting part 113′ is spaced apart from the first base 64 in the longitudinal direction, the included angle between the first heating part 111 and / or the second heating part 112 and the connecting part 113′ can be an obtuse angle, so that at least part of the airflow entering the atomizing chamber 63 through the vent 643 can be blown obliquely toward the first heating part 111 and / or the second heating part 112.

[0112] In some embodiments, reference may be made to Figure 14 and Figure 15The first heating part 111 and the second heating part 112 both extend from the connecting part 113′ toward the proximal end 51, so 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.

[0113] 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 attached to 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.

[0114] In some embodiments, reference may be made to Figure 5 and Figure 11 The vent 643 includes a first vent 6431 located near the first heating part 111 and a second vent 6432 located 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.

[0115] In some embodiments, reference may be made to Figure 5 and Figure 11 The first base 64 includes a base 645 and a guide member 644 disposed between the first vent 6431 and the second vent 6432.

[0116] 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.

[0117] As an example, you can refer to Figure 5At 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 in the atomizing chamber 63, which is conducive to concentrating more airflow in the central area of ​​the first heating part 111, thereby also helping to reduce the temperature of the central area of ​​the first heating part 111, which is beneficial to preventing the central area of ​​the first heating part 111 from dry burning.

[0118] As an example, you can refer to Figure 12 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.

[0119] As an example, the first guide surface 6441 at least partially defines a portion of the boundary of the first vent 6431.

[0120] In some embodiments, reference may be made to Figure 5 and Figure 11 The guide member 644 has a second guide surface 6442 corresponding to the second vent 6432. The second guide surface 6442 is inclined along the airflow direction or relative to the surface where the second heating part 112 is located, so as to guide the airflow that enters the atomization chamber 63 through the second vent 6432 to be blown obliquely toward the second heating part 112.

[0121] As an example, you can refer to Figure 5 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 in the atomizing chamber 63, which is conducive to concentrating more airflow into the central area of ​​the second heating part 112, thereby also helping to reduce the temperature of the central area of ​​the second heating part 112, which is beneficial to preventing the central area of ​​the second heating part 112 from dry burning.

[0122] As an example, you can refer to Figure 12 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.

[0123] As an example, the second guide surface 6442 at least partially defines a portion of the boundary of the second vent 6432.

[0124] 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.

[0125] Preferred options can be referenced. Figure 5 and Figure 11 The flow guide 644 is configured as a wedge shape, 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.

[0126] In some embodiments, reference may be made to Figure 11 and Figure 12 The guide member 644 extends away from the proximal end 51, so that the guide member 644 is located outside the atomizing chamber 63. This allows the connecting part 113′ to be horizontally arranged and closely attached to the mounting surface 641, while extending in a straight line or along a plane between the first heating part 111 and the second heating part 112, thereby reducing the lateral extension length of the connecting part 113′.

[0127] 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. Figure 8 and Figure 12 In the embodiment shown, 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.

[0128] In some embodiments, reference may be made to Figure 13 The connecting portion 113' is horizontally connected to the first base 64. The guide member 644 includes a first support surface 6411 facing the proximal end 51, and the base 645 includes a second support surface 6412 facing the proximal end 51. At least a portion of the connecting portion 113' is 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.

[0129] In some embodiments, reference may be made to Figure 14 and Figure 15 The connecting part 113′ is horizontally arranged and connected to the first base 64. The heating element 11 is also provided with a hollow hole 1131 for connecting the vent 643 and the atomizing chamber 63.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] The first and second perforated holes can be spaced apart by the connecting part 113'.

[0134] In other embodiments, the first and second perforations may also be formed on the connecting portion 113'.

[0135] In some embodiments, the heating element 11 further includes a first pin 114 and a second pin 115, and the first heating part 111, the connecting part 113 / 113', and the second heating part 112 are sequentially electrically connected between the first pin 114 and the second pin 115. Thus, when the heating element 11 establishes a conductive path with the power supply assembly 100 through the first pin 114 and the second pin 115, the first heating part 111 and the second heating part 112 form a series connection between the positive and negative terminals of the power supply assembly 100, so that the first heating part 111 and the second heating part 112 have the same operating current.

[0136] In some embodiments, the heating element 11 further includes a third pin 116 electrically connected to the connection portion 113 / 113′. Thus, the first heating portion 111 is electrically connected between the first pin 114 and the third pin 116, and the second heating portion 112 is electrically connected between the second pin 115 and the third pin 116.

[0137] The first pin 114 and the second pin 115 can be electrically connected to the same electrode of the power supply assembly 100, while the third pin 116 can be electrically connected to another electrode of the power supply assembly 100.

[0138] The power supply assembly 100 can make the first heating part 111 and the second heating part 112 have the same operating voltage through the first pin 114, the second pin 115 and the third pin 116. Of course, the first heating part 111 and the second heating part 112 can also have different operating voltages and different operating currents.

[0139] The aerosol generating device may also include a controller, which can control the power output of the power supply component 100 and control the power supply component 100 to output power to the heating element 11 through at least two of the first pin 114, the second pin 115 and the third pin 116, so that the first heating part 111 and the second heating part 112 can work independently. Thus, the controller can select at least one of the first heating part 111 and the second heating part 112 to work, or can adjust the working power of the first heating part 111 and the second heating part 112 separately.

[0140] In some embodiments, reference may be made to Figure 12 The end of the first pin 114 is located on the same side as the base surface 642 of the first base 64, so as to facilitate the electrical connection between the end of the first pin 114 and the corresponding electrode.

[0141] Furthermore, the first heating part 111 is held on the first base 64 and the first heating part 111 is located on the side of the first base 64 away from the base surface 642, that is, the first heating part 111 and the mounting surface 641 are on the same side. In order to save materials, it is preferable that the first pin 114 passes through the first base 64, so that the end of the first pin 111 is on the same side as the base surface 642 of the first base 64.

[0142] Furthermore, the end of the first pin 114 is bent to be substantially parallel to the base surface 642, thereby forming the first abutment portion 1141.

[0143] In some embodiments, reference may be made to Figure 12 The end of the second pin 115 is located on the same side as the base surface 642 of the first base 64, so as to facilitate the electrical connection of the end of the second pin 115 with the corresponding electrode.

[0144] Furthermore, the second heating part 112 is held on the first base 64 and the second heating part 112 is located on the side of the first base 64 away from the base surface 642, that is, the second heating part 112 and the mounting surface 641 are on the same side. In order to save materials, it is preferable that the second pin 115 passes through the first base 64, so that the end of the second pin 115 is on the same side as the base surface 642 of the first base 64.

[0145] Furthermore, the end of the second pin 115 is bent to be substantially parallel to the base surface 642, thereby forming the second abutment portion 1151.

[0146] In some embodiments, reference may be made to Figure 9 and Figure 15 The end of the third pin 116 is located on the same side as the base surface of the first base 64, so as to facilitate the electrical connection between the end of the third pin 116 and the corresponding electrode.

[0147] Furthermore, the connecting portion 113 / 113′ is located on the side of the first base 64 away from the base surface 642, that is, the connecting portion 113 / 113′ and the mounting surface 641 are on the same side. In order to save materials, it is preferable that the third pin 116 passes through the first base 64, so that the end of the third pin 116 is on the same side as the base surface 642 of the first base 64.

[0148] Furthermore, the end of the third pin 116 is bent to be substantially parallel to the base surface, thereby forming the third abutment portion 1161.

[0149] In some embodiments, reference may be made to Figure 6 and Figure 12 The support assembly 64 also 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 suction assembly 12, for example, so that the first heating part 111 is in close contact with the first liquid suction assembly 121, thereby improving the atomization efficiency of the first heating part 111.

[0150] 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.

[0151] 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.

[0152] In some embodiments, reference may be made to Figure 8 , Figure 13 and Figure 14 The first base 64 is provided with a positioning part 646, and the flexible member 65 is provided with a positioning mating part 651. The positioning part 646 and the positioning mating part 651 are fitted together, so that the flexible member 65 can be stably held on the first base 64, and the positioning part 646 can provide support so that the flexible member 65 can abut against the first heating part 111 and / or the second heating part 112.

[0153] As an example, you can refer to Figure 14The positioning and fitting part 651 includes a positioning groove provided inside the flexible member 65, and the positioning part includes a positioning post extending from the second support toward the proximal end of the atomizer, the positioning post being interference-fitted into the positioning groove.

[0154] As an example, the positioning part 645 includes a first positioning part 6451 and a second positioning part 6452 spaced apart, and the flexible member 65 is at least partially interference-fitted between the first positioning part 6451 and the second positioning part 6452.

[0155] In some embodiments, reference may be made to Figure 15 The connecting portion 113' is horizontally disposed and adjacent to the mounting surface 641, and the connecting portion 113' has a clearance space for the positioning portion 645 and / or the flexible member 65 to pass through. Further, the end of the flexible member 65 disposed away from the proximal end 51 contacts the connecting portion 113' and is supported longitudinally by the connecting portion 113'. Alternatively, the mounting surface 641 of the first base 64 contacts and supports the flexible member 65 longitudinally. Further, the second support surface 6412 contacts and supports the flexible member 65 longitudinally.

[0156] In some embodiments, reference may be made to Figure 6 , Figure 11 and Figure 18 The support assembly 6 includes a first support 61 and a second support 62, which are manufactured independently and can be connected to each other by assembly. After the first support 61 and the second support 62 are connected, at least a portion of the atomizing core 1 is held or clamped between the first support 61 and the second support 62, and at least a portion of the atomizing chamber 63 may also be located between the first support 61 and the second support 62. In other words, after the first support 61 and the second support 62 are connected, a holding cavity for mounting the atomizing core 1 is defined between the first support and the second support.

[0157] The first support 61 defines a first inlet 611, and the second 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 core 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 core 1, and then atomized by the atomizing core 1 to generate aerosol.

[0158] In some embodiments, reference may be made to Figure 6 , Figure 11 and Figure 18The liquid absorption assembly 12 includes a first liquid absorption assembly 121 and a second liquid absorption assembly 122, which are independently arranged. The first liquid absorption assembly 121 is disposed corresponding to the first heating part 111, and the first heating part 111 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, and the second heating part 112 is mainly used to atomize the aerosol generation matrix on the second liquid absorption assembly 122.

[0159] In some embodiments, the first 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 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.

[0160] In some embodiments, the process of combining the support assembly 6 with the atomizing core 1 includes: (1) obtaining mutually discrete atomizing core 1, first support 61 and second support 62; (2) connecting the first support 61 and second support 62, wherein after the first support 61 and second support 62 are connected to each other, a retaining cavity is formed between the first support 61 and second support 62; and (3) assembling at least a portion of the atomizing core 1 into the retaining cavity for retention.

[0161] In some embodiments, the assembly process of the support assembly 6 and the atomizing core 1 includes: (1) obtaining the mutually discrete atomizing core 1, the first support 61, and the second support 62; (2) assembling the atomizing core 1 with the first support 61, wherein the first support 61 and the second support 62 are still mutually discrete; and (3) connecting the first support 61 and the second support 62, such that at least a portion of the atomizing core 1 is enclosed between the first support 61 and the second support 62, and the atomizing core 1 is connected to the first inlet 611 and the second inlet 621. This facilitates easier and more convenient assembly of the atomizing core 1 between the first support 61 and the second support 62, and also reduces damage to the atomizing core 1 during assembly.

[0162] In some embodiments, the assembly process of the support assembly 6 and the atomizing core 1 includes: (1) obtaining a mutually discrete heating element 11, a first liquid absorption assembly 121, a second liquid absorption assembly 122, a first support 61, and a second support 62; (2) assembling the first liquid absorption element 121 into a first holding cavity 612 defined by the first support 61, and assembling the second liquid absorption element 122 into a second holding cavity 622 defined by the second support 62; (3) combining the heating element 11 with the first support 61, at which time the first support 61 and the second support 62 are still mutually discrete; (4) connecting the first support 61 and the second support 62, such that at least a portion of the heating element 11 is surrounded between the first support 61 and the second 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 core 1 is formed after the first support 61 and the second support 62 are connected. The assembly process provided in this embodiment helps to automate the assembly of the bracket assembly 6 and the atomizing core 1, thereby significantly improving the production efficiency of the atomizer 200.

[0163] Furthermore, before connecting the first bracket 61 and the second bracket 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 bracket 61 by connecting the first base 64.

[0164] Furthermore, when the first bracket 61 is connected to the second bracket 62, the first base 64 is also connected to the second bracket 62.

[0165] In some embodiments, the first bracket 61 and the second bracket 62 are directly physically connected to each other. In some embodiments, the first bracket 61 and the second bracket 62 are connected by a first base 64, and the first bracket 61 and the second bracket 62 may not have direct contact, or they may have direct physical contact.

[0166] In some embodiments, reference may be made to Figure 5 and Figure 11 The first support 61 includes a third sidewall 613, on which a first outlet 614 is provided for connecting the first inlet 611 and the atomizing core 1. The first liquid absorption 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 absorption assembly 121 in the lateral direction. The first outlet 614 is opened on the third sidewall 613, so that the first liquid absorption assembly 121 can conduct aerosol generation matrix to the first heating part 111 in the lateral direction.

[0167] 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.

[0168] 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.

[0169] In some embodiments, the second 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 core 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 abutting against the second liquid-absorbing assembly 122 in the lateral direction. The second outlet 624 is formed on the fourth sidewall 623, so that the second liquid-absorbing assembly 122 can conduct aerosol generation matrix to the second heating part 112 in the lateral direction.

[0170] 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.

[0171] 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.

[0172] In some embodiments, the first base 64 extends laterally, and the first support 62 and the second support 62 are correspondingly connected at opposite ends of the first base 64 in the lateral direction.

[0173] In some embodiments, the first support 61 has a first receiving cavity 615 for receiving at least a portion of the first base 64, and the first support 61 includes a first support portion 616, which includes a wall defining a partial boundary of the first holding cavity 612. The first support portion 616 is 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.

[0174] 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.

[0175] In some embodiments, the first bracket 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 bracket 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 bracket 62 is connected, the third support portion 617 can also prevent the first base 64 from detaching longitudinally.

[0176] 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 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.

[0177] 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.

[0178] In some embodiments, the second bracket 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 bracket 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 bracket 61 is connected, the fourth support portion 627 can also prevent the first base 64 from detaching longitudinally.

[0179] In some embodiments, the first bracket 61 and the second bracket 62 are snap-fitted together so that they can remain in a combined state after being combined.

[0180] For example, the first bracket 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 bracket 62 is provided with a first fastening engagement part (not shown). When the first bracket 61 and the second bracket 62 are connected, the first connecting arm 618 guides the first bracket 61 and the second bracket 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 bracket 61 and the second bracket 62 from separating laterally.

[0181] As an example, the second bracket 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 bracket 61 is provided with a second fastening engagement portion (not shown). When the first bracket 61 and the second bracket 62 are connected, the second connecting arm 628 guides the first bracket 61 and the second bracket 62 to combine 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 bracket 61 and the second bracket 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.

[0182] As an example, the first bracket 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 bracket 62 is provided with a third fastening engagement part 630'. When the first bracket 61 and the second bracket 62 are connected, the third connecting arm 618' guides the first bracket 61 and the second bracket 62 to combine with each other laterally until the third fastening part 619' and the third fastening engagement part 630' are engaged. 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 engaged, thus preventing the first bracket 61 and the second bracket 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 bracket 61, and the first connecting arm 618 and the third connecting arm 618' are disposed on opposite sides of the first bracket 61. Similarly, the first fastening engagement part and the third fastening engagement part 630' are disposed on opposite sides of the second bracket.

[0183] As an example, the second bracket 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 bracket 61 is provided with a fourth fastening engagement part. When the first bracket 61 and the second bracket 62 are connected, the fourth connecting arm 628' guides the first bracket 61 and the second bracket 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 bracket 61 and the second bracket 62 from separating laterally. Furthermore, the second fastening part 629 and the fourth fastening part 629′ are disposed on opposite sides of the second bracket 62, and the second connecting arm 628 and the fourth connecting arm 628′ are disposed on opposite sides of the second bracket 62. Similarly, the second fastening engagement part and the fourth fastening engagement part are disposed on opposite sides of the first bracket 61.

[0184] As an example, the first bracket 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 provided on opposite sides of the first bracket 61, and the first connecting arm 618 and the third connecting arm 618′ are provided at different longitudinal heights of the first bracket. 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 bracket 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′.

[0185] Meanwhile, the second bracket 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 bracket 62, and the second connecting arm 628 and the fourth connecting arm 628′ are located at different longitudinal heights of the second bracket 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 bracket 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′.

[0186] When the first bracket 61 and the second bracket 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 mating part, and the second fastening part 619' is snapped into the second fastening mating 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 mating part.

[0187] Thus, when the first bracket 61 and the second bracket 62 are connected, the first bracket 61 is connected by the first connecting arm 618 and the third connecting arm 618', and the second bracket 62 is connected by the second connecting arm 628 and the fourth connecting arm 628', so that the first bracket 61 and the second bracket 62 hug each other.

[0188] As an example, you can refer to Figure 18 The second bracket 62 includes a mating groove a, and the first bracket 61 includes a mating portion b. When the first bracket 61 and the second bracket 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 positioned so that the first bracket 61 and the second bracket 62 are laterally connected. Further still, the second bracket 62 is also provided with a laterally extending third connecting arm 628 and a fourth connecting arm 628', which are located on opposite sides of the second bracket 62. In this embodiment, the third connecting arm 628 and the fourth connecting arm 628' can be positioned at the same longitudinal height of the second bracket 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 bracket 62 is provided with a second fastening engagement portion 620 and a fourth fastening engagement portion. When the first bracket 61 and the second 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 the second fastening engagement part 620, and the third fastening part 629' is snapped into the fourth fastening engagement part.

[0189] It should be noted that the connection between the first bracket 61 and the second bracket 62 via snap-fit ​​is optional, not mandatory. For example, the first bracket 61 and the second bracket 62 can also be connected by welding and / or screws to maintain their combined state. Furthermore, the first bracket 61 and the second bracket 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 bracket 61 and the second bracket 62, and capable of inwardly pressing the first bracket 61 and the second bracket 62 so that the first bracket 61 and the second bracket 62 are close together.

[0190] It should be noted that combining the first support 61 and the second support 62 in a transverse direction is optional, not mandatory. For example, in other embodiments, the first support 61 and the second support 62 can also be combined in a longitudinal direction. After combination, the first support 61 and the second support 62 are mainly arranged in a transverse direction.

[0191] In some embodiments, reference may be made to Figure 2 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 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 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.

[0192] In some embodiments, the first 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 support 61. The first seal 66 may be made of silicone.

[0193] As an example, the first seal 66 has a first annular portion surrounding the first bracket 61, with a portion of the first annular portion disposed between the first bracket 61 and the second bracket 62. The first annular portion can resiliently abut against the second bracket 62 or the second seal 67, thereby providing a seal between the first bracket 61 and the second bracket 62. Alternatively, the first annular portion can be spaced apart from the second bracket 62. A portion of the first annular portion can be disposed between the first bracket 61 and the housing 2, thereby providing a seal between the first bracket 61 and the housing 2.

[0194] 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 support 61 and the second support 62 can be reduced in the interval between the first annular portion and the distal end 52. In other words, when the first annular portion is disposed adjacent to the first top wall c, the proximal end of the first support 61 can establish a sealing connection with the proximal end of the second support 62 or with the partition 7. Since the first seal 66 can prevent the aerosol generating matrix from flowing across the first seal 66 to the middle region and / or the distal end of the first support 61, not only can less aerosol generating matrix adhere to the outer wall of the first support 61, reducing aerosol generating matrix waste, but even if there is a connection gap between the first support 61 and the distal end of the first support 61 and the second support 62, the first seal 66 can isolate the storage cavity 21 and the connection gap, thereby preventing the aerosol generating matrix in the storage cavity 21 from leaking from the connection gap between the first support 61 and the second support 62. Therefore, the connection method of the first support 61 and the second support 62 can be simplified and the process requirements for connecting the first support 61 and the second support 62 can be reduced, which helps to improve production efficiency and reduce production costs, and can also effectively prevent the aerosol generating matrix from leaking through the support assembly 6.

[0195] As an example, a portion of the air duct 3 is surrounded by a first support 61 and a second support 62, and a portion of a 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.

[0196] As an example, you can refer to Figure 2 The atomizer 200 also includes a partition 7, which is disposed within the housing 2 and divides 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 core 1, and a second inlet 621 is used to guide the aerosol generating matrix in the second storage chamber 212 to the atomizing core 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 between the air guide tube 3 and the first support 6.

[0197] Furthermore, the atomizing core 1 includes a first liquid-absorbing component 121 corresponding to the first heating unit 111 and a second liquid-absorbing component 122 corresponding to the second heating unit 112. A first inlet 611 guides the aerosol-generating matrix in the first storage cavity 211 to the first liquid-absorbing component 121 for atomization by the first heating unit 111 to generate a first aerosol. A second inlet 621 guides the aerosol-generating matrix in the second storage cavity 212 to the second liquid-absorbing component 122 for atomization by the second heating unit 112 to generate a second aerosol. When the aerosol-generating matrix stored in the first storage cavity 211 and the aerosol-generating matrix stored in the second storage cavity 212 have the same composition, the generated first aerosol and second aerosol are the same. When the aerosol-generating matrix stored in the first storage cavity 211 and the aerosol-generating matrix stored in the second storage cavity 212 have different compositions, the first aerosol and second aerosol are different. When the first heating unit 111 and the second heating unit 112 are operating simultaneously, at least a portion of the first aerosol and at least a portion of the second aerosol can be mixed in the atomization chamber 63 and then guided to the outlet 41 via the air guide tube 3. When only one of the first heating unit 111 and the second heating unit 112 is operating, the air guide tube 3 guides either the first aerosol or the second aerosol to the outlet 41.

[0198] As an example, the first seal 66 and the first bracket 61 are integrally formed by in-mold injection molding. In particular, when the first seal 66 includes a first annular portion surrounding the first bracket 61 and the first bracket 61 has an irregular peripheral shape, in-mold injection molding helps to bond the first seal 66 to the first bracket, making the first seal 66 fit snugly against the first bracket 61.

[0199] In some embodiments, the second 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 support 62. The second seal 67 may be made of silicone.

[0200] As an example, the second seal 67 has a second annular portion surrounding the second bracket 62, with a portion of the second annular portion disposed between the first bracket 61 and the second bracket 62. The second annular portion can resiliently abut against the first bracket 61 or the first seal 66, thereby providing a seal between the first bracket 61 and the second bracket 62. Alternatively, the second annular portion can be spaced apart from the first bracket 61. A portion of the second annular portion can be disposed between the second bracket 62 and the housing 2, thereby providing a seal between the second bracket 62 and the housing 2.

[0201] The second inlet 621 is positioned facing the proximal end 51 or is located on the second top wall d, allowing the second annular portion to be positioned adjacent to the second top wall d. When the second annular portion is positioned adjacent to the second top wall d, the sealing requirements between the first support 61 and the second support 62 can be reduced within the interval between the second annular portion and the distal end 52. This simplifies the connection method of the first support 61 and the second support 62 and reduces the process requirements for connecting them, thus improving production efficiency and reducing production costs. It also effectively prevents leakage of the aerosol-generating matrix through the support assembly 6.

[0202] As an example, a portion of the air duct 3 is surrounded by a first support 61 and a second 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 the aerosol generating matrix from leaking from between the air duct 3 and the second support 62.

[0203] 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 air duct 3 and the second support 62.

[0204] Furthermore, the partition 7 is partially fitted between the first bracket 61 and the second bracket 62, and the opposite sides of the partition 7 elastically abut against the first seal 66 and the second seal 67, respectively.

[0205] As an example, the second seal 67 and the second bracket 62 are integrally formed by in-mold injection molding. In particular, when the second seal 67 includes a second annular portion surrounding the second bracket 62 and the second bracket 62 has an irregular peripheral shape, in-mold injection molding helps to bond the second seal 67 to the second bracket 62, making the second seal 67 fit snugly against the second bracket 62.

[0206] 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.

[0207] It should be noted that separator 7 is optional, not mandatory. (In the example...) Figure 16 In the embodiment shown, the first inlet 611 and the second inlet 621 are connected to the same storage cavity.

[0208] In some embodiments, reference may be made to Figure 16The first inlet 611 is located on the first top wall c, and the second inlet 621 is located on the second top wall d. The bracket assembly 6 also includes a sealing member 68. The annular portion of the sealing member 68 is arranged around the first bracket 61 and the second bracket 62, and provides a seal between the first side wall e and the outer shell 2, and between the second side wall f and the outer shell 2. At the same time, the annular portion of the sealing member 68 can also tightly clamp the first bracket 61 and the second bracket 62 together, so that the first bracket 61 and the second bracket 62 remain in the combined state.

[0209] The first inlet 611 is disposed or opened on the first top wall c facing the proximal end 51, and the second inlet 621 is disposed or opened on the second top wall d facing the proximal end 51. This allows the sealing member 68 to be disposed adjacent to the first top wall c and the second top wall d, and to tightly clamp the first bracket 61 and the second bracket 62 at the adjacent first top wall c and the second top wall d. When the sealing member 68 is disposed adjacent to the first top wall c and the second top wall d, the sealing requirements between the first bracket 61 and the second bracket 62 can be reduced in the interval between the sealing member 68 and the distal end 52. Therefore, the connection method of the first bracket 61 and the second bracket 62 can be simplified and the process requirements for connecting the first bracket 61 and the second bracket 62 can be reduced, which helps to improve production efficiency and reduce production costs, and can also effectively prevent the leakage of aerosol generation matrix through the bracket assembly 6.

[0210] As an example, you can refer to Figure 18 The first bracket 61 is provided with a retaining groove g, a portion of the air guide tube 3 is located in the retaining groove g, and the sealing element 68 provides a seal between the first bracket 61 and the air guide tube 3.

[0211] 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.

[0212] Of course, the first part and the second part can also be independent of each other.

[0213] As an example, the first support 61 and the second 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 support 61 and the air duct 3, and the second seal 67 provides a seal between the second support 62 and the air duct 3.

[0214] In some embodiments, reference may be made to Figure 2 and Figure 16 The first support 61 is provided with a first outlet 614 that connects to the atomizing core 1 and a first channel h that connects 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 core 1.

[0215] 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 intake assembly 121 to maintain the acquisition of the aerosol generation matrix. This helps ensure that the atomizer core 1 has sufficient aerosol generation matrix for atomization and helps prevent the atomizer core 1 from dry-burning.

[0216] As an example, the cross-sectional area of ​​the first outlet 614 near the atomizing core 1 or near the holding cavity of the atomizing core 1 is different from the cross-sectional area of ​​the first outlet 614 away from the atomizing core 1 or near the first channel h, in order to regulate the flow rate of the aerosol generating matrix from the first channel h to the atomizing core 1. Furthermore, the cross-sectional area of ​​the first outlet 614 near the atomizing core 1 or near the holding cavity of the atomizing core 1 is larger than the cross-sectional area of ​​the first outlet 614 away from the atomizing core 1 or near the first channel h, in order to reduce the flow rate of the aerosol generating matrix from the first channel h to the atomizing core 1, preventing leakage of the aerosol generating matrix due to excessive flow rate.

[0217] As an example, the first outlet 614 has multiple outlets to ensure that a sufficient aerosol generation matrix is ​​directed to the atomizing core 1, thereby preventing the atomizing core 1 from burning dry.

[0218] 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.

[0219] 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 core 1 from burning dry.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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 core 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.

[0224] As an example, the atomizing core 1 includes a first end facing away from the proximal end 51 and a second end facing the proximal end 51, with a first outlet 614 disposed adjacent to the first end. Further, the opening of the first outlet 614 facing the first liquid absorption assembly 121 is disposed adjacent to the first end of the first liquid absorption assembly 121, and the first heating part 111 is mainly located between the first and second ends. This allows the first liquid absorption assembly 121 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 first outlet 614 can be immersed in the aerosol generating matrix, allowing the first liquid absorption assembly 121 to maintain the intake of the aerosol generating matrix. This helps ensure that the atomizing core 1 has a sufficient amount of aerosol generating matrix for atomization and helps prevent the atomizing core 1 from dry burning.

[0225] In some embodiments, the second support 62 is provided with a second outlet 624 that connects to the atomizing core 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 core 1.

[0226] 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 intake assembly 122 to maintain the acquisition of the aerosol generation matrix. This helps ensure that the atomizing core 1 has sufficient aerosol generation matrix for atomization and helps prevent the atomizing core 1 from dry-burning.

[0227] As an example, the cross-sectional area of ​​the second outlet 624 near the atomizing core 1 or near the holding chamber of the atomizing core 1 is different from the cross-sectional area of ​​the second outlet 624 away from the atomizing core 1 or near the second channel j, in order to regulate the velocity of the aerosol generating matrix flowing from the second channel j to the atomizing core 1. Furthermore, the cross-sectional area of ​​the second outlet 624 near the atomizing core 1 or near the holding chamber of the atomizing core 1 is larger than the cross-sectional area of ​​the second outlet 624 away from the atomizing core 1 or near the second channel j, in order to reduce the velocity of the aerosol generating matrix flowing from the second channel j to the atomizing core 1, preventing leakage of the aerosol generating matrix due to excessive flow rate.

[0228] As an example, the second outlet 624 has multiple outlets to ensure that sufficient aerosol generation matrix is ​​directed to the atomizing core 1, thereby preventing the atomizing core 1 from burning dry.

[0229] 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.

[0230] 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. This ensures that the aerosol generation matrix can smoothly enter the second channel j, which helps to prevent the atomizing core 1 from burning dry.

[0231] 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.

[0232] 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.

[0233] 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.

[0234] 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 core 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.

[0235] As an example, the atomizing core 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 absorption assembly 122 is disposed adjacent to the first end of the second liquid absorption assembly 122, and the second heating part 112 is mainly located between the first and second ends. This allows the second liquid absorption 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 absorption assembly 122 to maintain the intake of the aerosol generating matrix. This helps ensure that the atomizing core 1 has a sufficient amount of aerosol generating matrix for atomization and helps prevent the atomizing core 1 from dry burning.

[0236] The second channel j is set independently of the first channel h.

[0237] 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.

[0238] The atomizer 200 may also include absorbent cotton 9, which is held between the first base 64 and the second base 8 to absorb aerosol and aerosol condensate that flow back through the vent 643 on the first base 64, thereby preventing aerosol and aerosol condensate from leaking out of the atomizer 200.

[0239] In some embodiments, the atomizer 200 further includes a first electrode 201 and a second electrode 202. The first electrode 201 is used for electrical connection with a first pin 114, and the second electrode 202 is used for electrical connection with a second pin 115. When the end of the first pin 114 includes a first abutment portion 1141 substantially parallel to the base surface 642 of the first base 64, the first electrode 201 is electrically connected to the first pin 114 through the first abutment portion 1141, instead of achieving the electrical connection between the first electrode 201 and the first pin 114 by soldering. Similarly, when the end of the second pin 115 includes a second abutment portion 1151, the second electrode 202 is electrically connected to the second pin 115 by abutting against the second abutment portion 1151.

[0240] When the heating element 11 further includes a third pin 116 connected to the connecting portion 113 / 113′, the atomizer 200 may also include a third electrode 203. When the end of the third pin 116 includes a third abutment portion 1161, the third electrode 203 is electrically connected to the third pin 116 by abutting the third abutment portion 1161.

[0241] In some embodiments, the first electrode 201 and the second electrode 202 are held on the second base 8, with one end of the first electrode 201 and the second electrode 202 away from the proximal end 51 exposed on the second base 8, so that when the atomizer 200 is engaged with the power supply assembly 100, the first electrode 201 and the second electrode 202 can be abutted by the output electrode associated with the power supply assembly 100.

[0242] When the third electrode 203 is present, the third electrode 203 can also be held on the second base 8, and the end of the third electrode 202 facing away from the proximal end 51 of the atomizer 200 can also be exposed on the second base 8.

[0243] In some embodiments, an air inlet 81 is provided on the second base 8. The air inlet 81 is used to guide air into the atomizer 200 and then into the atomization chamber 63 through the vent 643.

[0244] 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.
