[0002] This application claims priority to Chinese Patent Application No. 202510364348.7, filed on March 26, 2025, entitled “Atomizer and Electronic Atomizing Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and more particularly to an atomizer and electronic atomization device. Background Technology

[0004] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0005] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). The applicant has proposed an electronic atomizing device with an upper atomizing structure in patent CN221449912U, in which the atomizing surface of the atomizing component is arranged facing the outlet for the fastest possible aerosol output.

[0140] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0141] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0142] According to Figures 1 through 7, an electronic atomizing device in one embodiment includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply unit 200 that supplies power to the atomizer 100. In the embodiments shown in Figures 1 through 7, the atomizer 100 and the power supply unit 200 of the electronic atomizing device are detachable from each other; electronic atomizing devices with such detachable atomizer 100 and power supply unit 200 are, for example, so-called "refillable" electronic atomizing devices. Alternatively, in some other variations, the atomizer 100 and the power supply unit 200 of the electronic atomizing device are securely enclosed and fixed by a housing component of the electronic atomizing device, so that the atomizer 100 and the power supply unit 200 cannot be detachable from each other from within the housing component. Electronic atomizing devices with such non-detachable atomizer 100 and power supply unit 200 are, for example, so-called "integrated or disposable" electronic atomizing devices.

[0143] As shown in Figures 1 to 8, the power supply unit 200 includes:

[0144] The first end 210 and the second end 220 along the length direction;

[0145] The outer casing 230 extends from the first end 210 to the second end 220, defining the outer surface of the power supply body 200;

[0146] The receiving cavity 211 is defined within the housing 230 and near the first end 210, and is open at the first end 210; the receiving cavity 211 is for removably receiving at least a portion of the atomizer 100 through the open opening.

[0147] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0148] An electronic chamber, located between the receiving chamber 211 and the second end 220, is used to define an assembly space for mounting electronic devices such as the battery cell 240 and the circuit board 250.

[0149] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0150] The rigid support 260 is made of ceramic or polymer plastic, etc., and the support 230 is at least partially located between the receiving cavity 211 and the second end 220.

[0151] As shown in Figures 1 to 8, the rigid bracket 260 has a first support portion 261 and a second support portion 262 arranged in a longitudinal direction perpendicular to the power supply body 200; wherein the first support portion 261 and the second support portion 262 are arranged at intervals in the longitudinal direction.

[0152] In one embodiment, the bracket 260 further has sidewalls located at the first support portion 261 and the second support portion 262, connecting the first support portion 261 and the second support portion 262, and at least partially surrounding and enclosing the battery cell 240 from the outside to provide support.

[0153] In one embodiment, the first support portion 261 is at least partially located between the receiving cavity 211 and the electronic chamber to separate or define the receiving cavity 211 and the electronic chamber. Alternatively, at least a portion of the boundary of the receiving cavity 211 is separated and defined by the first support portion 261. Alternatively, the first support portion 261 defines the longitudinal length of the receiving cavity 211. And after assembly, the first support portion 261 is at least partially located between the battery cell 240 and the receiving cavity 211, and isolates the battery cell 240 and the receiving cavity 211.

[0154] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0155] Battery cell 240 and circuit board 250 are located within the electronic chamber. Battery cell 240 is used for power supply; circuit board 250 is used for controlling the power output of battery cell 240. Battery cell 240 is longitudinally housed or held between first support portion 261 and second support portion 262. Circuit board 250 is arranged substantially perpendicular to the longitudinal direction of power supply body 200; circuit board 250 is located between second support portion 262 and distal end 220. Circuit board 250 is securely connected to second support portion 262 by fasteners such as screws.

[0156] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0157] A charging interface 222, such as a USB-Type-C interface, is located at the second end 220 and is used to charge the battery cell 240. In this embodiment, the charging interface 222 can be directly connected to the circuit board 250 by soldering or the like, which is more advantageous than separating the charging interface 222 from the circuit board 250 and then connecting it via leads or the like.

[0158] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0159] The flexible first buffer element 241 and the flexible second buffer element 242 may be made of flexible silicone or polyurethane foam, etc. The first buffer element 241 is at least partially disposed between the battery cell 240 and the first support portion 261 to provide cushioning between them.

[0160] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0161] A first magnetic element 271 is arranged adjacent to the receiving cavity 211. When at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the first magnetic element 271 magnetically attracts the second magnetic element 171 on the atomizer 100, thereby stably receiving or holding the atomizer 100 within the receiving cavity 211.

[0162] As shown in Figures 1 to 8, the power supply unit 200 also includes:

When at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the first electrical contact 272 abuts against a second electrical contact 172 on the atomizer 100 to form a conductive connection, thereby providing power output from the battery cell 240 to the atomizer 100. The first electrical contact 272 is securely mounted or arranged on a first support portion 261 of the bracket 260; alternatively, the first electrical contact 272 extends longitudinally through the first support portion 261 of the bracket 260. Furthermore, the first electrical contact 272 extends from the electronic chamber into the receiving cavity 211. In an embodiment, the first electrical contact 272 is connected to a circuit board 250 via soldered wire leads, thereby establishing a conductive connection with the circuit board 250.

[0164] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0165] The first air inlet 221 provides an entrance for external air to enter the power supply unit 200; the first air inlet 221 is connected to the receiving cavity 211;

[0168] The gap located between the bracket 260 / cell 240 and the outer casing 230;

[0169] The trachea 282 extends longitudinally through the first support portion 261 of the support 260; the trachea 282 defines a communication port for air to enter the receiving cavity 211. The trachea 282 is rigid, for example, made of rigid ceramic or metal alloy.

[0170] As shown by arrow R2, during use, external air enters through the first air inlet 221, passes longitudinally through the gap between the bracket 260 / battery cell 240 and the outer shell 230, and then flows into the air tube 282 through the gap between the battery cell 240 and the first support part 261. After passing through the air tube 282, it enters the receiving chamber 211 and then enters the atomizer 100.

[0171] As shown in Figures 1 to 8, the power supply unit 200 also includes:

[0172] An airflow sensor 290 is used to sense changes in airflow through the e-cigarette device / air intake channel during user inhalation. The airflow sensor 290 is securely mounted or held to a first support portion 261 of a bracket 260. The airflow sensor 290 is enclosed by a flexible sealing element 281. The sealing element 281 is made of silicone or a thermoplastic elastomer, etc. The sealing element 281 at least partially provides cushioning between the airflow sensor 290 and the first support portion 261. In an embodiment, an air tube 282 passes through the sealing element 281. The airflow sensor 290 is arranged offset from the longitudinal central axis of the e-cigarette device.

[0173] As shown in Figure 8, the sealing element 281 at least partially passes through the first support portion 261 and is exposed within the receiving cavity 211; the sealing element 281 has an exposed surface located in the receiving cavity 211.

[0174] As shown in Figure 8, the power supply unit 200 also includes:

[0175] A sensing connection channel is at least partially formed or arranged on the exposed surface of the sealing element 281 located in the receiving cavity 211. The airflow sensor 250 is connected to the communication port of the air intake channel located in the receiving cavity 211 via the sensing connection channel, thereby enabling the airflow sensor 290 to sense changes in airflow through the electronic atomizing device / air intake channel when the user inhales.

[0176] As shown in Figure 8, the sensing connection channel includes:

[0177] An air groove 284 is formed on the exposed surface of the sealing element 281 located in the receiving cavity 211, and an air hole 285 extends from the air groove 284 to the airflow sensor 290. The air groove 284 extends between the air hole 285 and the communication port of the air intake passage located in the receiving cavity 211. As shown in FIG8, a sensing connection channel is at least partially formed on the inner surface of the receiving cavity 211 opposite to the opening. The sensing connection channel extends at least partially from the receiving cavity 211 through the sealing element 281 to the airflow sensor 290. In the embodiment shown in FIG8, the sensing connection channel is substantially formed or defined within the sealing element 281.

[0178] As shown in Figure 8, the sealing element 281 is further arranged on the exposed surface of the receiving cavity 211 with:

[0179] The annular rib 283 is a closed ring. The air groove 284, air hole 285, and air intake channel are all located within and surrounded by the annular rib 283. When the atomizer 100 is received in the receiving cavity 211, the rib 283 abuts against and blocks it, preventing the air groove 284 from being squeezed or compressed by the atomizer 100 and thus contracting or closing.

[0180] As shown in Figures 3-7 and Figures 9 to 16, the atomizer 100 includes:

[0181] The proximal end 110 and the distal end 120 are longitudinally opposite to each other; wherein, according to the needs of normal use, the proximal end 110 is configured as the end for the user to inhale aerosol, and an air outlet 111 for the user to inhale is provided in the proximal end 110; while the distal end 120 is the end that is connected to the power supply unit 200.

[0182] As shown in Figures 3-7 and Figures 9-16, the atomizer 100 includes several components disposed within a housing 10 (which may be referred to as a shell). The overall design of the housing 10 is variable, and the type or configuration of the housing 10 that defines the overall size and shape of the atomizer 100 is variable. Typically, the housing 10 may be formed from a single integral shell, or the housing 10 may be formed from two or more separable bodies. In some examples, all or only part of the housing 10 may be formed from a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, etc. As shown in Figures 9-16, the housing 10 includes: a first shell 11 and a second shell 12 joined longitudinally; the first shell 11 is adjacent to and defines a proximal end 110, and the second shell 12 is adjacent to and defines a distal end 120.

[0183] To facilitate modular production and assembly of the atomizer 100, in this embodiment, the atomizer 100 includes a first module 130 and a second module 140. During production, the first module 130 and the second module 140 are first assembled separately, and then they are joined longitudinally to form a complete atomizer 100. In this embodiment, the second module 140 of the atomizer 100 is a functional module that stores a liquid matrix and atomizes it to generate an aerosol, while the first module 130 is a functional module that outputs the aerosol to the outlet 111 for the user to inhale.

[0184] In some embodiments, after the first module 130 and the second module 140 are longitudinally combined to assemble a complete atomizer 100, the first module 130 can be detached from the second module 140 by user operation. For example, in some embodiments, the first module 130 and the second module 140 are combined in the product packaging of the atomizer 100; during use, the first module 130 can be detached from the second module 140 by user operation. Or in other embodiments, the first module 130 cannot be detached or separated from the second module 140 after being assembled into the atomizer 100.

[0185] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 includes:

[0186] The second housing 12 is basically a cylindrical shape extending longitudinally along the atomizer 100; the second housing 12 is open or vented toward the proximal end 110; the second housing 12 has partition walls 121 arranged longitudinally perpendicular to the atomizer 100.

[0187] A reservoir 124 is provided for storing a liquid matrix. The reservoir 124 is defined within the second housing 12, or the second housing 12 surrounds and defines the reservoir 124. More specifically, the reservoir 124 is substantially defined by the cylindrical sidewalls of the second housing 12 and the partition wall 121. The side of the reservoir 124 near the distal end 120 is closed by the partition wall 121; and the side of the reservoir 124 near the proximal end 110 is open or exposed.

[0188] In some embodiments, the second housing 12 is transparent, for example, made of transparent plastic. This allows the remaining amount of liquid matrix in the reservoir 124 to be viewed through the second housing 12.

[0189] As shown in Figure 8 of Figure 3, the outer casing 230 of the power supply unit 200 is further provided with at least one or more windows 212. In use, when the atomizer 100 is received within the receiving cavity 211 of the power supply unit 200, at least a portion of the second housing 12 is received within the receiving cavity 211, and the first housing 11 is exposed outside the receiving cavity 211. Furthermore, in use, the remaining amount of liquid matrix in the liquid storage chamber 124 within the second housing 12 can be viewed through the windows 212.

[0190] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0191] A sealing element 15 is attached to the opening of the second housing 12 facing the proximal end 110 and seals the liquid reservoir 124. In an embodiment, the sealing element 15 may be arranged substantially perpendicular to the longitudinal extension of the atomizer 100. In an embodiment, the sealing element 15 is made of a rigid material such as plastic or ceramic.

[0192] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0193] The flexible sealing element 14 may be made of flexible silicone or thermoplastic elastomer, etc.; the sealing element 14 is at least partially located between the closure element 15 and the second housing 12 to provide a seal between them. The sealing element 14 at least partially covers or encloses the surface of the closure element 15 facing the proximal end 110.

[0194] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0195] Atomizing assembly 30 is used to receive a liquid matrix originating from the reservoir 124 and atomize it to generate an aerosol. In an embodiment, the atomizing assembly 30 is at least partially located within the sealing element 14 and / or the closure element 15. Furthermore, the atomizing assembly 30 is arranged relatively closer to the proximal end 110 than the reservoir 124.

[0196] As shown in Figures 9 to 16, the atomizing component 30 includes:

[0197] Porous element 31 and heating element 32 incorporated in porous element 31.

[0198] In some embodiments, the porous element 31 is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the porous element 31 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the atomizer 100. Alternatively, in some other variations, the porous element 31 may also include a rigid porous element, such as porous ceramic or porous glass. The outer surface of the porous element 31 is in liquid communication with the first segment 161 of the capillary element 16, thereby the outer surface of the porous element 31 is used to absorb the liquid matrix, as shown by arrow R1 in Figures 6 and 7.

[0199] In some embodiments, the inner surface of the porous element 31 in the radial direction is configured as an atomizing surface, which is combined / attached / abutted to the heating element 32; subsequently, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 32 to generate an aerosol and released. Referring to Figures 9 to 16, the heating element 32 is arranged to extend longitudinally along the porous element 31, and the heating element 32 is coaxially arranged with the porous element 31. In some optional embodiments, the heating element 32 may be a resistance heating mesh, a resistance heating coil, etc. In this embodiment, the heating element 32 is a heating element wound from a sheet-like or mesh-like substrate. Conductive leads 321 are welded or arranged on the heating element 32, and current is guided on the heating element 32 through the conductive leads 321.

[0200] In some variations, the heating element 32 may be bonded to the porous element 31 by means of printing, deposition, sintering, or physical assembly. In some other variations, the porous element 31 may have a planar or curved surface for supporting the heating element 32, which is formed on the planar or curved surface of the porous element 31 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 32 may be a conductive trace formed on the surface of the porous element 31. In some variations, the conductive trace of the heating element 32 may be in the form of printed lines formed by printing. In some variations, the heating element 32 may be a patterned conductive trace. In some variations, the heating element 32 may be planar. In some variations, the heating element 32 may be a tortuous, meandering, reciprocating, or bent conductive trace.

[0201] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0202] The capillary element 16 extends from the reservoir 124 into the sealing element 14 and / or the closure element 15. In some embodiments, the capillary element 16 is flexible, for example, made of flexible capillary fiber materials such as cotton fibers, nonwoven fibers, sponge, or silk fibers; or in other embodiments, the capillary element 16 is rigid, for example, made of rigid porous ceramic bodies, porous glass, etc.

[0203] In one embodiment, the capillary element 16 is used to transfer the liquid matrix in the reservoir 124 toward the proximal end 110 to the atomizing assembly 30. In another embodiment, the capillary element 16 is arranged along the longitudinal central axis of the atomizer 100.

[0204] In this embodiment, the capillary element 16 is a hollow tubular shape. The capillary element 16 abuts longitudinally against the partition wall 121 to provide a stop.

[0205] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0206] A tubular support wall 122 is located at least partially within the capillary element 16, thereby providing support for the capillary element 16 within it. In an embodiment, the capillary element 16 is arranged to enclose or surround the support wall 122.

[0207] In one embodiment, the support wall 122 is arranged to extend from the partition wall 121 toward the proximal end 110. In another embodiment, the support wall 122 and / or the partition wall 121 are integrally molded with the second housing 12. Therefore, after fabrication, the support wall 122 and the partition wall 121 are integrally fastened together. Alternatively, in yet another embodiment, the support wall 122, the partition wall 121, and the second housing 12 are fabricated separately and then assembled together.

[0208] In this embodiment, the longitudinal extension length of the support wall 122 is less than the longitudinal extension length of the capillary element 16.

[0209] As shown in Figures 9 to 16, the capillary element 16 may include a first segment 161 and a second segment 162 arranged longitudinally; wherein the first segment 161 is closer to the proximal end 110.

[0210] In one embodiment, the second section 162 is located within the reservoir 124 to draw in the liquid matrix; and the second section 162 is arranged to surround or enclose the support wall 122. The first section 161 extends through the sealing element 14 and / or the closure element 15, or the first section 161 extends into the sealing element 14 and / or the closure element 15. Upon assembly, the second section 162 is bonded to and held on the support wall 122; or, the second section 162 is located within the reservoir 124. The first section 161 extends outside the reservoir 124; and the first section 161 extends into the sealing element 14 and is thus surrounded by the sealing element 14.

[0211] In some embodiments, at least one longitudinally extending capillary groove or rib is arranged on the outer surface of the support wall 122; for example, in some embodiments, the outer surface of the support wall 122 has a plurality of capillary grooves or ribs arranged at intervals in the circumferential direction. In embodiments, at least one longitudinally extending capillary channel is formed or defined between the support wall 122 and the capillary element 16 by the capillary groove or rib. At least one longitudinally extending capillary channel is advantageous in that it can overcome the gravity of the liquid matrix by capillary adsorption or capillary action, thus facilitating the delivery of the liquid matrix to the atomizing assembly 30.

[0212] In a more specific embodiment, at least one capillary channel is formed between the second segment 162 of the capillary element 16 and the support wall 122. Furthermore, at least one capillary channel may extend to the porous element 31; after assembly, at least one capillary channel is connected to the porous element 31.

[0213] As shown in Figures 9 to 16, the atomizing component 30 is housed and held within the first section 161 of the capillary element 16; in use, the outer surface of the porous element 31 draws liquid matrix from the reservoir 124 from the first section 161 of the capillary element 16. Alternatively, in some other embodiments, the porous element 31 is surrounded and held by the first section 161 of the capillary element 16 and contacts the first section 161 to form fluid communication.

[0214] As shown in Figures 9 to 16, the atomizing component 30 and / or the porous element 31 are substantially longitudinally abutted against the support wall 122, and are thus at least partially supported or held by the support wall 122. Alternatively, in some other embodiments, the atomizing component 30 and / or the porous element 31 have a longitudinal gap greater than 0.1 mm from the support wall 122, thereby creating a gap between the porous element 31 and the support wall 122 rather than contact.

[0215] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0216] A tubular element 40 is at least partially located within a first section 161 of a capillary element 16; a porous element 31 is held within the tubular element 40. At least one or more liquid perforations 42 are arranged on the wall of the tubular element 40; after assembly, the liquid perforations 42 are surrounded or covered by the first section 161 of the capillary element 16. The porous element 31 can draw liquid matrix originating from the reservoir chamber 124 from the first section 161 of the capillary element 16, at least through the liquid perforations 42 of the tubular element 40.

[0217] Alternatively, as shown in Figures 9 through 16, at least a portion of the porous element 31 extends beyond the tubular element 40, thereby drawing in the liquid matrix by directly contacting the first segment 161 of the capillary element 16.

[0218] As shown by arrow R1 in the figure, during use, the liquid matrix in the storage chamber 124 is delivered from the second section 162 to the first section 161, and then absorbed by the porous element 31 and delivered to the heating element 32 for atomization.

[0219] In some embodiments, the tubular element 40 is longitudinally joined to the support wall 122 by riveting or clamping. After assembly, the tubular element 40 and the support wall 122 are sealed, and therefore no flexible sealing material is provided between them.

[0220] In the embodiments shown in Figures 9 to 16, the tubular element 40 and the support wall 122 are each separately manufactured and then assembled. After assembly, the support wall 122 is at least partially inserted into the tubular element 40 for secure connection. Alternatively, in some other variations, the tubular element 40 and the support wall 122 are integrally molded. Alternatively, the tubular element 40 may be defined by a portion of the support wall 122, or the support wall 122 may be defined by a portion of the tubular element 40.

[0221] In some embodiments, the outer diameter d52 of the capillary element 16 is approximately 4 to 10 mm; and the capillary element 16 has a length of approximately 30 to 60 mm. In some embodiments, the tubular capillary element 16 has a wall thickness of approximately 0.5 to 3.0 mm.

[0222] In this embodiment, the length of the second segment 162 is equal to the length of the support wall 122, approximately 20–40 mm; the length of the first segment 161 is approximately 5–20 mm. The length of the first segment 161 is less than the length of the second segment 162.

[0223] In this embodiment, the inner diameter of the capillary element 16 is less than or equal to the outer diameter of the tubular element 40. Therefore, after assembly, interference is formed between the first segment 161 of the capillary element 16 and the tubular element 40 to maintain sufficient compression or contact between the capillary element 16 and the tubular element 40. This is advantageous for allowing the porous element 31 to adequately draw liquid matrix from the first segment 161 of the capillary element 16. In a more preferred embodiment, the inner diameter of the capillary element 16 is approximately 0 to 0.6 mm smaller than the outer diameter of the tubular element 40.

[0224] In some embodiments, the end of the capillary element 16 near or toward the proximal end 110 protrudes further than the atomizing component 30 / porous element 31. Alternatively, the atomizing component 30 / porous element 31 is located within the first segment 161 of the capillary element 16 and does not extend beyond or protrude from the capillary element 16. In some alternative embodiments, the end of the capillary element 16 near or toward the proximal end 110 is flush with the atomizing component 30 / porous element 31. Alternatively, in some embodiments, the longitudinal distance between the end of the capillary element 16 near or toward the proximal end 110 and the atomizing component 30 / porous element 31 is greater than or equal to 0 mm; more preferably, the longitudinal distance between the end of the capillary element 16 near or toward the proximal end 110 and the atomizing component 30 / porous element 31 is between 0.2 and 2.0 mm.

[0225] In one embodiment, the tubular element 40 extends at least partially from within the capillary element 16 toward the proximal end 110 or extends through the capillary element 16. After assembly, the tubular element 40 is at least partially exposed outside the first segment 161 of the capillary element 16. In some embodiments, the portion of the tubular element 40 extending outside the first segment 161 of the capillary element 16 has a length of approximately 0.4 to 4.0 mm.

[0226] As shown in Figures 9 to 16, the sealing element 14 has a central aperture 144 through which a first segment 161 of the capillary element 16 passes or extends; the first segment 161 of the capillary element 16 at least partially extends into the central aperture 144. A fence 141 extending toward the proximal end 110 is also arranged on the sealing element 14; the fence 141 at least partially surrounds or defines the central aperture 144. In an embodiment, the fence 141 is annular.

[0227] After assembly, the first segment 161 of the capillary element 16 is at least partially located within and surrounded by the enclosure 141. The enclosure 141 is not in contact with the first segment 161 of the capillary element 16. There is a gap of approximately 0.5 to 3.0 mm between the enclosure 141 and the first segment 161 of the capillary element 16. In an embodiment, the gap between the enclosure 141 and the first segment 161 of the capillary element 16 defines a first air cavity 163 surrounding the first segment 161 of the capillary element 16.

[0228] In one embodiment, an air communication hole 41 is arranged on the wall of the tubular element 40; the air communication hole 41 is located on the portion of the tubular element 40 extending beyond the first segment 161 of the capillary element 16. Furthermore, the air communication hole 41 avoids the capillary element 16 and / or the atomizing assembly 30. More specifically, the air communication hole 41 is closer to the proximal end 110 than the capillary element 16 and the atomizing assembly 30. For example, as shown in FIG. 9, the air communication hole 41 is exposed outside the first segment 161 of the capillary element 16.

[0229] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0230] An end cap 19 is disposed at the distal end 120 and attached to the second housing 12. Alternatively, the end cap 19 is formed or attached to the distal end 120 of the second housing 12. The end cap 19 may be connected to the second housing 12 by riveting or mechanical means. The end cap 19 may be made of rigid plastic or ceramic, etc.

[0231] As shown in Figures 9 to 16, the atomizer 100 also includes:

[0232] An air inlet 123, disposed on the end cap 19, is located or defined for supplying air into the atomizer 100 during inhalation. When at least a portion of the atomizer 100 is received and housed within the receiving chamber 211, the air inlet 123 is aligned and connected to the air intake passage of the power supply unit 200 at the communication port / air tube 282 located in the receiving chamber 211. Air enters the atomizer 100 from the air intake passage of the power supply unit 200 via the air inlet 123.

[0233] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0234] The second magnetic element 171 is securely arranged on the end cap 20. When at least a portion of the atomizer 100 is received and housed in the receiving cavity 211, the second magnetic element 171 is magnetically attracted to the first magnetic element 271 of the power supply body 200, thereby stably receiving or holding the atomizer 100 in the receiving cavity 211.

[0235] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0236] The second electrical contact 172 extends at least partially from the distal end 120 through the end cap 20 into the contact hole 127 on the partition wall 121. The second electrical contact 172 is at least partially exposed at the distal end 120. When at least a portion of the atomizer 100 is received and housed within the receiving cavity 211, the second electrical contact 172 and the first electrical contact 272 of the power supply body 200 abut against each other to form a conductive connection for supplying power from the battery cell 240 to the atomizer 100.

[0237] As shown in Figures 9 to 16, the following are also formed or defined on the surface of the partition wall 121 facing the distal end 120:

[0238] A contact hole 127 is provided for at least partially receiving and retaining the second electrical contact 172. The contact hole 127 is defined by a first raised edge 128 surrounding the surface of the partition wall 121.

[0239] After assembly, the conductive lead 321 extends longitudinally through the holes 129 of the support wall 122 and the partition wall 121 and is then bent at least partially into the contact hole 127, where it conducts electricity by contacting or welding with the second electrical contact 172.

[0240] In one embodiment, a wire groove 1281 is also arranged on the first protrusion 128. The conductive lead 321 is at least partially confined and held within the wire groove 1281.

[0241] As shown in Figures 9 to 16, the second module 140 of the atomizer 100 also includes:

[0242] A porous absorber element 18, for example made of a flexible porous fibrous material, is located between the partition wall 121 and the end cap 19 to absorb aerosol condensate falling from the support wall 122 to the air inlet 123. The absorber element 18 may be made of fibrous materials such as fiber cotton, sponge, or silk fibers.

[0243] As shown in Figures 9 to 16, the first module 130 of the atomizer 100 includes:

[0244] The first housing 11 and the absorption element 13 located within the first housing 11.

[0245] In one embodiment, the first housing 11 has at least one first connecting portion 115 extending toward the distal end 120; the first connecting portion 115 has a first connecting structure 116. The second housing 12 has at least one second connecting portion 125; the second connecting portion 125 has a second connecting structure 126. Specifically, the first connecting structure 116 may be a connecting hole, a connecting groove, etc., arranged on the first connecting portion 115. The second connecting structure 126 may be a connecting protrusion, etc., arranged on the second connecting portion 125.

[0246] In the assembly of the first module 130 and the second module 140, the first connecting part 115 of the first housing 11 extends into the second connecting part 125 aligned with the second housing 12 for assembly; and the first connecting structure 116 and the second connecting structure 126 cooperate to connect and fasten the first module 130 and the second module 140.

[0247] In one embodiment, the first housing 11 defines an outlet 111 at the proximal end 110; and an aerosol channel 112 extending from the outlet 111 toward the distal end 120 for discharging aerosols.

[0248] In one embodiment, the first housing 11 further includes an annular retaining wall 113; the absorption element 13 is housed and retained within the retaining wall 113. The retaining wall 113 extends longitudinally. After the first module 130 and the second module 140 of the atomizer 100 are assembled, the retaining wall 113 abuts longitudinally against the surface of the sealing element 14 facing the proximal end 110. Furthermore, the retaining wall 113 is located outside and around the enclosure 141 of the sealing element 14. After assembly, a gap exists between the retaining wall 113 and the enclosure 141, and this gap forms or defines a second air cavity 114 located between the retaining wall 113 and the enclosure 141.

[0249] In this embodiment, the enclosure 141 of the sealing element 14 has a plurality of notches 143 arranged thereon; the plurality of notches 143 are arranged at intervals in the circumferential direction. Thus, the second air cavity 114 is in air communication with the first air cavity 163 through the notches 143.

[0250] In this embodiment, the porous absorber element 13 may be made of a porous fibrous material, such as fiber cotton, sponge, silk fiber, etc. After the first module 130 and the second module 140 of the atomizer 100 are assembled, the enclosure 141 of the sealing element 14 abuts against the absorber element 13 longitudinally, at least partially supporting the absorber element 13 longitudinally. In this embodiment, the absorber element 13 is annular. After assembly, at least a portion of the tubular element 40 extends into or is inserted into the absorber element 13. And, when at least a portion of the tubular element 40 is inserted into the absorber element 13, the air communication hole 41 avoids the absorber element 13.

[0251] In an embodiment, a first air cavity 163 and / or a second air cavity 114 are formed or defined longitudinally between the absorption element 13 and the sealing element 14 of the atomizer 100. The first air cavity 163 and / or the second air cavity 114 are separated by a fence 141 of the sealing element 14. Furthermore, the first air cavity 163 and / or the second air cavity 114 are in air communication through a notch 143 in the fence 141.

[0252] As indicated by arrow R2 in Figures 7, 8, and 10, the atomizer 100 also defines:

[0253] The airflow channel defines the path of air from the air inlet 123 through the atomizing assembly 30 / heating element 32 to the air outlet 111, so as to output the aerosol to the air outlet 111. In the path shown by arrow R2, the airflow channel runs substantially longitudinally through the atomizer 100; and the airflow channel is substantially without bends.

[0254] In this embodiment, the complete airflow channel is defined by multiple components; the complete airflow channel includes:

[0255] The central hole formed on the absorption element 18;

[0256] Hole 129 of partition wall 121;

[0257] The hollow space within the tubular support wall 122;

[0258] The cylindrical atomizing component 30 is hollow;

[0259] The tubular element 40 is partially hollow;

[0260] Aerosol channel 112.

[0261] When the user inhales, the flow path in the airflow channel of the atomizer 100 is as shown by arrow R2. The air entering from the air inlet 123 passes through the absorption element 18 and the hole 129 of the partition wall 121 in sequence and enters the support wall 122. Then it passes through the support wall 122 and enters the atomizing assembly 30, and then carries the aerosol from the aerosol channel 112 to the air outlet 111 for the user to inhale.

[0262] In one embodiment, the airflow channel is at least partially defined by a support wall 122.

[0263] In this embodiment, the first air cavity 163 is in air communication with the airflow channel through the air communication hole 41 of the tubular element 40. When the user draws air, the negative pressure of the airflow channel can be transmitted to the first air cavity 163, thereby generating a negative pressure outside the first section 161 of the capillary element 16, which promotes the wetting and transfer of the liquid matrix from the second section 162 to the first section 161.

[0264] In this embodiment, the outer surface of the first section 161 is in communication with the airflow channel. Specifically, the outer surface of the first section 161 is in air communication with the airflow channel through the air communication hole 41 of the tubular element 40.

[0265] As indicated by arrow R3 in Figures 9 and 15, the atomizer 100 also includes:

[0266] A ventilation channel is provided to connect the liquid storage chamber 124 with the airflow channel, thereby balancing the pressure between the liquid storage chamber 124 and the outside. Specifically, as the negative pressure inside the liquid storage chamber 124 gradually increases due to the consumption of the liquid matrix, air can enter the liquid storage chamber 124 through the ventilation channel to alleviate and balance the negative pressure in the liquid storage chamber 124.

[0267] In this embodiment, the complete path of the ventilation channel is defined by multiple components; specifically, as shown in Figures 9 and 15, the ventilation channel includes at least:

[0268] At least one or more ventilation holes 142 are formed or arranged on the sealing element 14; the ventilation holes 142 pass through the sealing element 14 along the longitudinal direction of the atomizer 100;

[0269] At least one or more ventilation slots 152 are formed or arranged on the enclosure element 15; specifically, the ventilation slots 152 extend longitudinally through the enclosure element 15 and are located on the peripheral surface of the enclosure element 15.

[0270] An air gap 153 is formed between the sealing element 14 and the closing element 15 to provide communication between the air exchange groove 152 and the air exchange hole 142.

[0271] In use, as shown by arrow R3 in Figures 9 and 15, when the negative pressure in the liquid storage chamber 124 exceeds a predetermined threshold, the air in the airflow channel enters the first air chamber 163 through the air communication hole 41 on the tubular element 40, and then enters the second air chamber 114 through the notch 143 on the fence 141; finally, it enters the liquid storage chamber 124 from the second air chamber 114 through the ventilation hole 142, the air gap 153 and the ventilation groove 152 in sequence, thereby relieving or regulating the pressure of the liquid storage chamber 124.

[0272] In one embodiment, a ventilation channel is formed or arranged between the proximal end 110 and the liquid reservoir 124. More specifically, the ventilation channel is at least partially formed between the second air cavity 114 and the liquid reservoir 124. In another embodiment, the ventilation channel is at least partially formed or defined by the sealing element 14 and / or the closure element 15.

[0273] As shown in Figure 15, the closure element 15 is also provided with at least one or more pins 151; in one aspect, these pins 151 extend at least partially into or insert into the vent 142 to provide support in order to prevent the flexible sealing element 14 from being squeezed or otherwise compressed during assembly, which would cause the vent 142 to be compressed or closed; in another aspect, the pins 151 can provide positioning and connection during the assembly of the closure element 15 and the sealing element 14.

[0274] As shown in Figure 15, after assembly, the retaining wall 113 of the first housing 11 abuts against the surface of the sealing element 14 facing the proximal end 110, and avoids the vent 142. The vent 142 is located within the retaining wall 113.

[0275] In one embodiment, an annular rib 146 is further arranged on the surface of the sealing element 14 facing the proximal end 110; the rib 146 is aligned with the retaining wall 113 of the first housing 11 in the longitudinal direction of the atomizer 100. After assembly, the retaining wall 113 of the first housing 11 longitudinally abuts against the rib 146 and at least partially compresses or squeezes the rib 146 to provide a seal between the retaining wall 113 and the sealing element 14.

[0276] As shown in Figure 15, the first housing 11 also has a second flange 115 extending longitudinally from the aerosol channel 112 toward the distal end 120. In an embodiment, the second flange 115 is annular in shape. After assembly, the second flange 115 is inserted into the absorption element 13, and the absorption element 13 is arranged at least partially around the second flange 115.

[0277] As shown in Figure 15, after assembly, the second protrusion 115 is longitudinally aligned with the tubular element 40, but not abutting or connected. In Figure 15, the distance between the second protrusion 115 and the tubular element 40 is, for example, approximately 0.1 to 1.0 mm; and the aerosol condensate falling from the inner surface of the aerosol channel 112 onto the second protrusion 115 is adsorbed and transferred to the absorption element 13 for absorption by capillary adsorption of this distance.

[0278] Furthermore, during use, on the one hand, the liquid or condensate mixed in the aerosol during user suction can be adsorbed by the absorption element 13, and on the other hand, the condensate falling from the inner surface of the aerosol channel 112 under the action of gravity can be transferred to the absorption element 13 for absorption, so as to minimize the risk of the outlet 111 receiving condensate.

[0279] As shown in Figure 15, the second protruding edge 115 is coaxially arranged with the porous element 31; and the second protruding edge 115 and the porous element 31 are spaced apart longitudinally. Furthermore, the inner diameter d31 of the porous element 31 is smaller than the inner diameter d115 of the second protruding edge 115. In some optional embodiments, the inner diameter d115 of the second protruding edge 115 is 0 mm to 2.0 mm larger than the inner diameter d31 of the porous element 31.

[0280] As shown in Figures 15 and 16, the inner diameter of the central hole 144 of the sealing element 14 is not constant. In the embodiment shown in Figure 15, the central hole 144 is a stepped hole with a varying inner diameter. In some embodiments, a portion of the inner surface of the central hole 144 contacts or abuts against the outer surface of the first segment 161 of the capillary element 16, and a portion has a gap 147 between it and the outer surface of the first segment 161 of the capillary element 16. The gap 147 has a width of approximately 0.5 mm; or the gap 147 is between 0.1 and 1.0 mm. After assembly, the gap 147 communicates with the first air cavity 163; furthermore, the gap 147 may also provide communication between the outer surface of the first segment 161 of the capillary element 16 and the airflow channel.

[0281] Specifically, as shown in Figure 16, the central hole 144 of the sealing element 14 has a first portion 1441 and a second portion 1442 arranged longitudinally in sequence; the first portion 1441 has an inner diameter slightly larger than that of the second portion 1442. Specifically, the inner diameter of the first portion 1441 is 0.5 to 1.0 mm larger than that of the second portion 1442.

[0282] After assembly, the inner surface of the second portion 1442 abuts or contacts the first segment 161 of the capillary element 16, which is advantageous for preventing the liquid matrix of the reservoir 124 from seeping between them. A gap 147 is formed or defined between the inner surface of the first portion 1441 and the first segment 161 of the capillary element 16.

[0283] In some embodiments, the length d41 of the first portion 1441 is slightly greater than the length d42 of the second portion 1442; specifically, the length d41 of the first portion 1441 is approximately 2 to 5 mm; and the length d42 of the second portion 1442 is approximately 1 to 3.5 mm.

[0284] In some embodiments, the inner diameter d51 of the second portion 1442 is slightly smaller than the outer diameter d52 of the first segment 161 of the capillary element 16. After assembly, the area where the first segment 161 of the capillary element 16 contacts the second portion 1442 interferes and is thus squeezed or compressed. In some specific embodiments, the inner diameter d51 of the second portion 1442 is 0 to 0.6 mm smaller than the outer diameter d52 of the first segment 161.

[0285] As shown in Figure 16, the liquid perforation 42 on the tubular element 40 is mainly opposite to the portion of the first section 161 that is surrounded by the first portion 1441.

[0286] Alternatively, in some embodiments, at least one third air cavity is further defined between the tubular support wall 122 and the capillary element 16. For example, in some specific embodiments, the third air cavity may be defined by an air groove on the outer surface of the tubular support wall 122. In some embodiments, the air groove defining the third air cavity may be annular around the support wall 122; or, the air groove defining the third air cavity may be longitudinally extending.

[0287] In some embodiments, the third air cavity may be in air communication with the first air cavity 163 / airflow channel via the slit 147; or in other embodiments, the third air cavity may be in communication with the airflow channel via other connecting channels. During suction, the negative pressure within the airflow channel can be transmitted to the third air cavity, thereby generating a negative pressure within the second section 162 of the capillary element 16 near the atomizing assembly 30, which promotes the wetting and transfer of the liquid matrix to the first section 161.

[0288] In some embodiments, the third air cavity may be spaced apart from the porous element 31; or, the third air cavity may be connected to the porous element 31.

[0289] In some embodiments, the third air cavity is relatively close to the atomizing assembly 30. Alternatively, the third air cavity is relatively closer to the first inner wall of the reservoir 121 facing the proximal end 110, and farther from the second inner wall of the reservoir 121 facing the distal end 120. The first inner wall of the reservoir 121 facing the proximal end 110 may be defined by the sealing element 15; the second inner wall of the reservoir 121 facing the distal end 120 may be defined by the partition wall 121.

[0290] Alternatively, in some embodiments, the distance between the third air cavity and the sealing element 15 is greater than the distance between the third air cavity and the partition wall 121.

[0291] 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.
