Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and a liquid reservoir. Background Technology

[0002] 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.

[0003] 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). In a known electronic atomizing device as proposed in Chinese Patent CN113995169A, a liquid matrix is ​​supplied to a reusable atomizing body via a separate, replaceable liquid source; when the liquid source is attached to the atomizing body, the stored liquid matrix is ​​delivered by the liquid source to the atomizing body for atomization to produce an aerosol.

[0088] 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.

[0089] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes a reservoir 100 for storing a liquid matrix, an atomizing body 200 for receiving the liquid matrix from the reservoir 100 and atomizing it to generate an aerosol, and a power supply body 300 for supplying power to the atomizing body 200. Figure 1 In the illustrated embodiment, any one of the liquid reservoir 100, atomizing body 200, and power supply body 300 of the electronic atomizing device can exist independently and be detached.

[0090] In some embodiments, the reservoir 100, the atomizing body 200, and the power supply body 300 can each exist independently, while also being combined to form a complete electronic atomization device. In some embodiments, the atomizing body 200 is used to atomize a liquid matrix to generate an aerosol, and the reservoir 100, when combined with the atomizing body 200, can replenish the liquid matrix to the atomizing body 200. Before the reservoir 100 and the atomizing body 200 are combined, they exist independently of each other.

[0091] In some embodiments, the power supply unit 300 provides power to the atomizing unit 200, thereby causing the atomizing unit 200 to atomize the liquid matrix. In some embodiments, when the atomizing unit 200 is attached to the power supply unit 300, a conductive connection can be established between them, thereby allowing the power supply unit 300 to provide power to the atomizing unit 200. Before being attached to the power supply unit 300, the atomizing units 200 exist independently of each other.

[0092] For example, in some embodiments, the reservoir 100, the atomizing body 200, and the power supply body 300 are packaged separately when the electronic atomizing device is sold or before it is used by the consumer. When used by the consumer, the atomizing body 200 is then attached to the power supply body 300, and the reservoir 100 is attached to the atomizing body 200.

[0093] In some embodiments, the reservoir 100 is used as a replacement consumable. After the reservoir 100 is used after being attached to the atomizing body 200 until the stored liquid matrix is ​​consumed, the reservoir 100 can be detached or removed from the atomizing body 200 to facilitate replacement with a new reservoir 100.

[0094] In some embodiments, the atomizing body 200 and the power supply body 300 are reusable.

[0095] exist Figure 1 and Figure 2 In the illustrated embodiment, the liquid reservoir 100, the atomizing body 200, and the power supply body 300 are sequentially and longitudinally combined to form an electronic atomizing device. When they are combined to form the electronic atomizing device, the atomizing body 200 is longitudinally located between the liquid reservoir 100 and the power supply body 300.

[0102] according to Figures 3 to 4 As shown, the power supply unit 300 also includes:

[0103] A rigid support element 330 is located within the housing 30 and extends longitudinally along the power supply body 300. The support element 330 is used to provide support for at least the battery cell 350 and the circuit board 360.

[0104] In one embodiment, the support element 330 includes a first support portion 331 and a second support portion 332 arranged longitudinally. The outer diameter of the first support portion 331 is smaller than the outer diameter of the second support portion 332. The battery cell 350 and the circuit board 360 are surrounded or enclosed by the second support portion 332, and are thus housed within the second support portion 332 and supported by it. The first support portion 331 is essentially in the shape of an annular fence.

[0105] In one embodiment, the first support portion 331 is closer to the upper end 310 and forms or defines a insertion groove 311 between it and the outer shell 30 for the atomizing body 200 to be inserted and connected.

[0106] according to Figures 3 to 4 As shown, the power supply unit 300 also includes:

[0107] Electrical contact 312 is electrically connected to circuit board 360. Electrical contact 312 extends longitudinally at least partially between circuit board 360 and upper end 310. Electrical contact 312 is at least partially exposed within insertion slot 311. In an embodiment, electrical contact 312 avoids the first support portion 331 of support element 330.

[0108] In an embodiment, when the atomizing body 200 is attached to the power supply body 300 from the upper end 310, an electrical contact 312 establishes a conductive connection between the atomizing body 200 and the circuit board 360, thereby enabling the circuit board 360 to control the supply of power to the atomizing body 200 via the electrical contact 312.

[0110] A first connecting structure 317 is formed or arranged on the housing 30; when the atomizing body 200 is attached to the power supply body 300 from the upper end 310, the first connecting structure 317 provides a mechanical connection with the atomizing body 200. In an embodiment, the first connecting structure 317 is a snap-fit ​​groove formed or arranged on the housing 30.

[0111] according to Figures 3 to 4 As shown, the power supply unit 300 also includes:

[0112] The positioning mechanism includes a first positioning protrusion 314 and a second positioning protrusion 315 spaced apart. The first positioning protrusion 314 and the second positioning protrusion 315 are located within the insertion groove 311 and extend longitudinally along the power supply body 300. A positioning slot 316 is formed or defined between the first positioning protrusion 314 and the second positioning protrusion 315. The positioning mechanism is used to provide positioning when the atomizing body 200 is attached to the power supply body 300 from the upper end 310. Specifically, the atomizing body 200 is provided with a positioning protrusion 225 that can be inserted into it; when the atomizing body 200 is attached to the power supply body 300 from the upper end 310, the positioning protrusion 225 is aligned and inserted into the positioning slot 316 to provide assembly positioning.

[0113] In some embodiments, the positioning mechanism is also used to prevent the atomizing body 200 attached to the power supply body 300 from rotating relative to the power supply body 300.

[0114] according to Figures 3 to 4 As shown, the power supply unit 300 also includes:

[0115] The sealing element 340 is made of flexible silicone, thermoplastic elastomer, or the like. The sealing element 340 is installed and arranged within the first support portion 331 of the support element 330. Furthermore, the sealing element 340 is at least partially exposed.

[0116] In this embodiment, a first air connection 341 is surrounded or defined on the sealing element 340. When the atomizing body 200 is attached to the power supply body 300, the first air connection 341 connects the atomizing body 200 and the first airflow channel R21 of the power supply body 300, thereby allowing air to enter the atomizing body 200. The first air connection 341 is surrounded and defined by the annular protrusion 342 of the sealing element 340. When the atomizing body 200 is attached to the power supply body 300, the atomizing body 200 longitudinally abuts against the sealing element 340, and the sealing element 340 provides an airtight seal between the atomizing body 200 and the power supply body 300.

[0117] according to Figures 3 to 4 As shown, the power supply unit 300 also includes:

[0118] The first airflow passage R21 provides a passage path for air to be delivered via the air inlet 321 at the lower end 320 to the first air communication port 341 defined by the sealing element 340.

[0119] In some embodiments, the first airflow passage R21 is defined by a plurality of components.

[0120] In some embodiments, the first airflow passage R21 is at least partially located between the housing 30 and the battery cell 350. Alternatively, the first airflow passage R21 is at least partially defined by a gap between the housing 30 and the battery cell 350.

[0121] In some embodiments, the first airflow channel R21 bypasses or crosses the circuit board 360.

Circuit board 360 can determine the user's inhalation action based on the sensing result of sensor 370 and control the supply of power to atomizing body 200.

[0126] In some embodiments, the sensor 370 is securely disposed on the circuit board 360 by means of soldering or the like. More specifically, the sensor 370 is disposed on the surface of the circuit board 360 facing the upper end 310.

[0129] according to Figure 3 and Figure 4As shown, the power supply unit 300 also includes:

[0130] A sensing connection channel R3 is used to connect sensor 370 to the air in the first airflow channel R21.

[0146] according to Figures 5 to 8 As shown, the atomizing component includes:

[0147] Porous element 240 and heating element 250 incorporated in porous element 240.

[0148] In some embodiments, the porous element 240 is flexible, for example, made of flexible fibers such as cotton fibers or nonwoven fabrics, or made of porous polymers such as sponges; the porous element 240 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the atomizing body 200. Alternatively, in some other variations, the porous element 240 may also include rigid porous elements, such as porous ceramics or porous glass.

[0149] In some embodiments, the outer surface of the porous element 240 is configured as a liquid-absorbing surface, thereby absorbing the liquid matrix. In some embodiments, the inner surface of the porous element 240 in the radial direction is configured as an atomizing surface, which is combined / adhered / abutted against the heating element 250; thereby, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 250 to generate an aerosol and released.

[0150] according to Figures 5 to 8 As shown, the heating element 250 is arranged to extend longitudinally along the porous element 240, and the heating element 250 is coaxially arranged with the porous element 240. In some alternative embodiments, the heating element 250 may be a resistance heating mesh, a resistance heating coil, etc. In this embodiment, the heating element 250 is formed by winding a sheet-like or mesh-like substrate. Conductive leads 251 are welded or arranged on the heating element 250, and current is guided on the heating element 250 through the conductive leads 251.

[0151] In some variations, the heating element 250 may be bonded to the porous element 240 by means of printing, deposition, sintering, or physical assembly. In some other variations, the porous element 240 may have a planar or curved surface for supporting the heating element 250, which is formed on the planar or curved surface of the porous element 240 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 250 may be a conductive trace formed on the surface of the porous element 240. In some variations, the conductive trace of the heating element 250 may be in the form of printed lines formed by printing. In some variations, the heating element 250 may be a patterned conductive trace. In some variations, the heating element 250 may be planar. In some variations, the heating element 250 may be a tortuous, meandering, reciprocating, or zigzag-extending conductive trace.

[0152] according to Figures 5 to 8 As shown, the tubular retaining element 230 may include a first segment 231, a second segment 232, and a third segment 233 arranged longitudinally. The first segment 231 is located closer to the first end 210. During assembly, the third segment 233 surrounds and engages with the support wall 213, thereby securely mounting the retaining element 230. In some embodiments, the third segment 233 is securely connected to the support wall 213 by riveting, interference fitting, or other means. In an embodiment, the tubular retaining element 230 abuts longitudinally against the partition wall 212 to form a stop.

[0153] In an embodiment, at least a portion of the outer diameter of the first segment 231 is reduced. At least a portion of the first segment 231 is configured as a shape with a contracted outer diameter; or, the first segment 231 is a constricted shape. In another embodiment, the first segment 231 defines the free end of the retaining element 230 facing the first end 210. When the reservoir 100 is received within the receiving cavity 211, at least a portion of the retaining element 230 is inserted into the reservoir 100. The first segment 231 defines an aerosol outlet for the output aerosol at its free end.

[0154] In some embodiments, the atomizing assembly / porous element 240 is housed and held within a second section 232. In some embodiments, a plurality of liquid guide holes 2321 are arranged on the second section 232 for the porous element 240 to receive a liquid matrix originating from the reservoir 100.

[0155] according to Figures 5 to 8 As shown, the atomizing body 200 also includes:

[0156] A flexible sealing element 260 is disposed within the housing 20 and longitudinally abuts against the partition wall 212. The sealing element 260 may be made of silicone, thermoplastic elastomer, or the like.

[0157] In this embodiment, the sealing element 260 is essentially sheet-like.

[0158] In one embodiment, the sealing element 260 is arranged around a portion of the third segment 233 of the retaining element 230.

[0159] After assembly, the sealing element 260 defines a portion of the boundary of the receiving cavity 211; more specifically, the sealing element 260 defines the receiving cavity 211 away from the bottom surface of the first end 210. When the reservoir 100 is received in the receiving cavity 211, the reservoir 100 abuts longitudinally against the sealing element 260, thereby providing a seal between the reservoir 100 and the atomizing body 200 by the sealing element 260.

[0160] In one embodiment, an assembly structure 261 is arranged on the surface of the sealing element 260 facing away from the partition wall 212. The assembly structure 261 provides an operating position for a jig or tooling device to assemble the sealing element 260 into the housing 20. Specifically, for example, the assembly structure 261 is a blind hole located on the surface of the sealing element 260; during assembly, a jig or tooling device extends into the assembly structure 261 to transfer the sealing element 260 from the first end 210 into the housing 20 and abut against the partition wall 212.

[0161] according to Figures 5 to 8 As shown, the atomizing body 200 also includes:

[0162] A generally annular or sheet-like covering element 280 is used to cover or block the conductive lead 251. Specifically, the conductive lead 251 connected to the heating element 250 extends between the covering element 280 and the partition wall 212 after passing through the gap between the support wall 213 and the third section 233 of the retaining element 230, and the first lead hole on the partition wall 212. In some embodiments, the conductive lead 251 connected to the heating element 250 extends through the gap between the third section 233 of the retaining element 230 and the support wall 213 to the first lead hole on the partition wall 212. Alternatively, in some other embodiments, the third section 233 of the retaining element 230 has a second lead hole through which the conductive lead 251 passes, extending from inside the retaining element 230 through the second lead hole to the outside of the retaining element 230, and extending between the sealing element 260 and the third section 233 of the retaining element 230 to the first lead hole on the partition wall 212.

[0163] according to Figures 5 to 8 As shown, the atomizing body 200 also includes:

[0164] A basic annular wire isolating element 270 is located within the retaining element 230. The wire isolating element 270 is situated between the support wall 213 and the atomizing assembly. The wire isolating element 270 is annular in shape and has several circumferentially spaced wire grooves arranged on its outer surface. During assembly, the two conductive leads 251 are confined within different wire grooves to form an isolation, thereby preventing problems such as short circuits caused by the two conductive leads 251 coming into contact with each other during assembly.

[0165] In one embodiment, the covering element 280 is provided with a contact hole 226; the conductive lead 251 extends at least partially into the contact hole 226. When the atomizing body 200 is attached to the power supply body 300, the electrical contact 312 on the power supply body 300 extends into or is inserted into the contact hole 226, thereby contacting or abutting against the conductive lead 251 to establish a conductive connection with the heating element 250.

[0166] In this embodiment, the electrical contacts 312 are arranged off-center from the center of the power supply body 300. Furthermore, there are two electrical contacts 312; the two contacts 312 are arranged non-centrally symmetrically about the central axis of the power supply body 300. Also in this embodiment, the two contact holes 226 are arranged non-centrally symmetrically about the central axis of the atomizing body 200.

[0167] In one embodiment, an air inlet 222 is also provided on the covering element 280. The air inlet 222 is aligned with and communicates with the annular support wall 213.

[0168] according to Figures 5 to 8 As shown, the atomizing body 200 also includes:

[0169] The second airflow channel R22 provides a channel path from the air inlet 222 through the atomizing component / heating element 250 to the aerosol outlet at the free end of the holding element 230.

[0170] In this embodiment, the second airflow channel R22 is arranged to extend along the central axis of the atomizing body 200.

[0171] according to Figure 8 In the embodiment shown, when the atomizing body 200 is attached to the power supply body 300, the annular protrusion 342 of the sealing element 340 of the power supply body 300 is inserted into the air inlet 222, thereby connecting the first airflow channel R21 and the second airflow channel R22.

[0172] according to Figure 8 In the illustrated embodiment, the second airflow passage R22 at least partially passes through the support wall 213. Furthermore, the gap between the rigid cover element 280 and the partition wall 212 is in airflow communication with the lead hole on the partition wall 212; during suction, the second airflow passage R22 is in communication with the gap between the rigid cover element 280 and the partition wall 212.

[0173] After assembly, the flexible sealing element 260 simultaneously shields and seals the gap between the support wall 213 and the third section 233 of the retaining element 230, the first lead hole, and / or the second lead hole. Thus, when the reservoir 100 is received in the receiving chamber 211 of the atomizing body 200, the flexible sealing element 260 provides airtight isolation between the receiving chamber 211 and the second airflow channel R22. In one aspect, this prevents negative pressure from the airflow during suction from being transmitted to the receiving chamber 211, causing air in the receiving chamber 211 to enter the suction airflow channel; in another aspect, when the reservoir 100 is removed, the negative pressure generated by the removal operation in the receiving chamber 211 will not be transmitted to the airflow channel, preventing false triggering of the sensor 370.

[0174] according to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the reservoir 100 includes:

[0175] A longitudinally extending outer casing 10 defines at least a portion of the outer surface of the reservoir 100. The outer casing 10 has a proximal end 110 and a distal end 120 facing away from each other. In use, the proximal end 110 is configured as the end where the user inhales the aerosol, and an outlet 111 for the user to inhale is provided at the proximal end 110; while the distal end 120 is configured as the end that extends into and engages with the atomizing body 200.

[0176] In an embodiment, a flange 11 is provided on the outer surface of the outer shell 10, which surrounds the outer shell 10 in the circumferential direction; when the liquid reservoir 100 is inserted into or received in the receiving cavity 211 from the first end 210 of the atomizing body 200, the flange 11 longitudinally abuts against the first end 210 of the atomizing body 200 to provide a stop.

[0177] In this embodiment, a mouthpiece for user aspiration is formed or defined by a portion of the housing 10 located between the proximal end 110 and the flange 11; and a space for storing the liquid matrix is ​​defined within a portion of the housing 10 located between the flange 11 and the distal end 120. When the reservoir 100 is received within the atomizing body 200, the portion of the housing 10 located between the proximal end 110 and the flange 11 is received within the receiving cavity 211 of the atomizing body 200; and the portion of the housing 10 located between the flange 11 and the distal end 120 is exposed outside the receiving cavity 211.

[0178] according to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the reservoir 100 includes:

[0179] Liquid storage chamber 12 is used to store liquid matrix;

[0180] At least one porous capillary element 15 is located within or fills the space of the liquid storage chamber; the capillary element 15 is used to adsorb and retain the liquid matrix stored in the liquid storage chamber 12.

[0181] In this embodiment, the capillary element 15 is annular. In this embodiment, the capillary element 15 is made of a flexible or rigid porous material or fibrous material, such as porous fiber cotton or sponge. Furthermore, when the reservoir 100 is received within the receiving cavity 211 of the atomizing body 200, the reservoir cavity 12 and the capillary element 15 are substantially completely contained within the receiving cavity 211.

[0182] In this embodiment, the liquid reservoir 12 is located between the flange 11 and the distal end 120.

[0183] according to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the reservoir 100 also includes:

[0184] A first sealing base 13 and a second sealing base 14 are arranged longitudinally within the housing 10.

[0185] The liquid reservoir 12 and / or capillary element 15 are defined or arranged between the first sealing base 13 and the second sealing base 14. The first sealing base 13 and the second sealing base 14 are made of flexible silicone or other materials.

[0186] In this embodiment, the capillary element 15 is held longitudinally between the first sealing base 13 and the second sealing base 14.

[0187] In one embodiment, the first sealing base 13 is relatively closer to the proximal end 110, and the second sealing base 14 is relatively closer to the distal end 120. In another embodiment, the second sealing base 14 closes the distal end 120 of the housing 10. The second sealing base 14 is attached to the distal end 120 of the housing 10.

[0188] In this embodiment, a plurality of protrusions 142 are arranged on the surface of the second sealing base 14 facing the liquid storage cavity 12. After assembly, the lower surface of the capillary element 15 abuts against the protrusions 142 and has a first gap space 143 between it and the second sealing base 14.

[0189] exist Figure 2 and Figure 10 In the illustrated embodiment, the outer casing 10 has a plurality of circumferentially spaced connecting holes 121; the second sealing base 14 has a plurality of circumferentially spaced locking protrusions 145. After assembly, the locking protrusions 145 of the second sealing base 14 extend into the connecting holes 121 of the outer casing 10, thereby fastening the second sealing base 14 to the outer casing 10. Figure 2 In the illustrated embodiment, the protrusion height of the latch 145 is greater than the wall thickness of the housing 10, so that at least a portion of the latch 145 extends beyond the outer surface of the housing 10 after assembly. For example, in some embodiments, the portion of the latch 145 extending beyond the housing 10 after assembly protrudes 0.1 to 1.5 mm more than the outer surface of the housing 10.

[0190] exist Figure 12 In the illustrated embodiment, when the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, the portion of the latch 145 extending outside the outer shell 10 abuts against the inner surface of the outer shell 20 of the atomizing body 200, and an interference fit is formed between the latch 145 and the outer shell 20 to generate frictional force to stably hold the reservoir 100 in the receiving cavity 211 of the atomizing body 200.

[0191] In this embodiment, a connector 141 extending longitudinally through the reservoir 100 is arranged on the second sealing base 14. The connector 141 is aligned with and communicates with the central hole of the annular capillary element 15. When the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, the holding element 230 of the atomizing body 200 is at least partially inserted from the connector 141 into the capillary element 15, thereby causing the porous element 240 located in the second section 232 of the holding element 230 to contact or communicate with the capillary element 15, thereby drawing the liquid matrix from the capillary element 15, such as... Figure 12As indicated by the middle arrow R1. In use, the liquid matrix can be delivered directly from the inner surface of the capillary element 15 to the porous element 240, which is advantageous for reducing the transport path of the liquid matrix.

[0192] according to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the reservoir 100 also includes:

[0193] A tubular element 16 is located within the capillary element 15 and is arranged along the longitudinal direction of the reservoir 100. In some embodiments, the tubular element 16 may include a fiberglass tube, a stainless steel tube, a ceramic tube, a glass tube, or a plastic tube, etc.

[0194] In some embodiments, the extension length of the tubular element 16 is less than the length of the capillary element 15 extending longitudinally along the reservoir 100; furthermore, the tubular element 16 is attached only to a portion of the inner surface of the capillary element 15, while avoiding another portion. Or, in a more specific embodiment, the inner surface of the capillary element 15 includes a first surface portion and a second surface portion arranged longitudinally; the first surface portion surrounds and holds the tubular element 16, while the second surface portion avoids the tubular element 16.

[0195] In some embodiments, the inner diameter of the tubular element 16 is slightly larger than or equal to the outer diameter of the first segment 231 of the holding element 230 of the atomizing body 200. And, the inner diameter of the tubular element 16 is slightly smaller than the outer diameter of the second segment 232 of the holding element 230 of the atomizing body 200.

[0196] In some embodiments, when the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, a first segment 231 of the holding element 230 of the atomizing body 200 is at least partially inserted into the tubular element 16, thereby connecting the holding element 230 to the tubular element 16. Also, when the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, a second segment 232 of the holding element 230 is surrounded or wrapped by a second surface portion of the inner surface of the capillary element 15. The porous element 240 is in liquid communication with the second surface portion of the inner surface of the capillary element 15 to draw in the liquid matrix.

[0197] In some embodiments, when the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, the second sealing base 14 at least partially surrounds or encloses at least a portion of the third segment 233 of the retaining element 230 to establish a seal between them.

[0198] In an embodiment, when the reservoir 100 is received in the receiving cavity 211 of the atomizing body 200, the second sealing base 14 longitudinally abuts against the sealing element 260 of the atomizing body 200.

[0199] according to Figure 1 , Figure 2 , Figures 9 to 12 As shown, the reservoir 100 also includes:

[0200] Air passage R23 defines the passage path from the insertion port 141 of the second sealing base 14 to the air outlet 111.

[0201] In this embodiment, the air passage R23 is defined by multiple components. Specifically, the housing 10 also has a tube wall 112 extending from the air outlet 111 to the distal end 120. Furthermore, an annular porous absorption element 113 is arranged between the tube wall 112 and the first sealing base 13. The absorption element 113 may include porous fiber cotton, sponge, etc., to absorb aerosol condensate flowing towards the air outlet 111.

[0202] In the embodiment, the airflow path of the air passage R23 formed between the insertion port 141 and the air outlet 111 can be defined by multiple components, including the pipe wall 112, the central hole of the absorption element 113, the hollow 131 of the first sealing base 13, the tubular element 16, and the second surface portion of the inner surface of the capillary element 15.

[0203] Alternatively, in some embodiments, a detachably connected mouthpiece element is also arranged on the first end 210 of the housing 20 of the atomizing body 200; and the mouthpiece element defines an outlet for discharging aerosol, thereby allowing the user to inhale the aerosol. The housing 10 of the reservoir 100 does not have a mouthpiece portion for inhalation. When the mouthpiece element is connected to the first end 210 of the housing 20, the receiving cavity 211 is blocked or closed; and when the mouthpiece element is detached from the first end 210 of the housing 20, the reservoir 100 can be received within the receiving cavity 211. And when the reservoir 100 can be received within the receiving cavity 211, the mouthpiece element can cover the reservoir 100 to prevent the reservoir 100 from being removed from the atomizing body 200.

[0204] In one embodiment, a second spacer space 151 is formed or defined between the inner surface of the reservoir 12 and the outer surface of the capillary element 15. In some embodiments, the inner surface of the reservoir 12 may have at least one or more longitudinally extending ridges or other protruding structures, which define the second spacer space 151 between the inner surface of the reservoir 12 and the outer surface of the capillary element 15. The second spacer space 151 is in communication with the first spacer space 143.

[0205] In some embodiments, the first partition space 143 is connected to the air channel R23, so that when the negative pressure gradually increases due to the consumption of the liquid matrix in the liquid reservoir 12 / capillary element 15, the second partition space 151 and / or the first partition space 143 are connected to the air channel R23 to balance the pressure of the liquid reservoir 12 / capillary element 15.

[0206] according to Figure 12 As shown, in the complete electronic atomizing device composed of the liquid reservoir 100, the atomizing body 200 and the power supply body 300, the complete airflow path when the user inhales is defined by a portion of the first airflow path R21 of the power supply body 300, the second airflow path R22 of the atomizing body 200 and the third airflow path R23 of the liquid reservoir 100.

[0207] When the user inhales, the pressure in the airflow channel and / or the first airflow channel R21 of the heating element 250 drops to a negative pressure or below a predetermined threshold. The sensor 370 can output an electrical signal, such as a high-level signal, indicating user inhalation when the sensed pressure is below the predetermined threshold. Furthermore, the control circuitry of the circuit board 360 is configured to control the power output to the heating element 250 based on the high-level signal output by the sensor 370.

[0208] In this embodiment, when the reservoir 100 is received within the atomizing body 200, the capillary element 15 is isolated from the airflow channel passing through the electronic atomizing device. Specifically, a first surface portion of the inner surface of the capillary element 15 is isolated from the airflow channel by a tubular element 16; a second surface portion of the inner surface of the capillary element 15 is isolated from the airflow channel by a retaining element 230. The tubular element 16 is arranged to extend axially along the capillary element 15.

[0209] In an embodiment, when the reservoir 100 is removed from the atomizing body 200, the second surface portion of the inner surface of the capillary element 15 is exposed to the air passage R23.

[0210] according to Figure 11 and Figure 12 As shown, during use, the user can first connect the second end 220 of the atomizing body 200 to the power supply body 300 to establish their conductive connection; then, as shown... Figure 11 As indicated by the middle arrow P11, the liquid reservoir 100 is received from the first end 210 of the atomizing body 200 into the receiving cavity 211 of the atomizing body 200 to form a complete electronic atomizing device. Furthermore, after assembly, the outer casing 30 of the power supply body 300, a portion of the outer casing 20 of the atomizing body 200, and a portion of the outer casing 10 of the liquid reservoir 100 collectively define the outer casing and / or outer surface of the electronic atomizing device.

[0211] exist Figure 13 In the illustrated embodiment, for example, as indicated by arrow P12, when the user removes or detaches the reservoir 100 from the electronic atomizing device after inhalation, the removal action generates a negative pressure in the receiving cavity 211 of the atomizing body 200. This negative pressure is transmitted to the sensor 370 via the airflow channel, potentially causing the sensor 370 to falsely trigger. In one embodiment, the control circuit of the circuit board 360 of the power supply body 300 is configured to delay the response to the sensing result of the sensor 370 to avoid controlling the power output to the heating element 250 in case of false triggering. Specifically, in an embodiment, the control circuit of the circuit board 360 of the power supply body 300 may be configured as follows:

[0212] During the first phase of the continuous electrical signal of sensor 370, the high-level pulse signal indicating the user's suction action output by sensor 370 is not responded to, thus preventing power output to heating element 250.

[0213] During the second time phase of the pulsed electrical signal of sensor 370, in response to the high-level pulse signal output by sensor 370 indicating the user's suction action, power is allowed or controlled to be output to heating element 250.

[0214] In some embodiments, the first time phase may typically be set to 0.2 to 0.8 s; more specifically, the first time phase may be set to 0.5 s.

[0215] Typically, the user's aspiration time is greater than 2 seconds, and more specifically, the user's aspiration time can be between 3 and 5 seconds; the duration during which the sensor 370 may be falsely triggered during the user's removal of the reservoir 100 is less than 0.8 seconds; therefore, the control circuit of the circuit board 360 does not respond to the high-level signal generated by the sensor 370 being triggered in the first phase, so as to avoid outputting power to the heating element 250 in the event of false triggering.

[0216] Alternatively, in some other embodiments, the control circuit of the circuit board 360 of the power supply unit 300 may be configured as follows:

[0217] Before the duration of the electrical signal generated by sensor 370 reaches a predetermined duration, the high-level signal indicating the user's suction action output by sensor 370 may not be responded to, thus preventing power output to heating element 250; and when the duration of the electrical signal generated by sensor 370 reaches the predetermined duration, the high-level signal indicating the user's suction action output by sensor 370 is responded to, allowing or controlling power output to heating element 250. Accordingly, the predetermined duration may typically be set to 0.2 to 0.8 s; more specifically, the predetermined duration may be set to 0.5 s.

[0218] according to Figure 2 , Figure 10 , Figure 12 and Figure 13 In the illustrated embodiment, to eliminate Figure 13 When the reservoir 100, indicated by the middle arrow P12, is removed individually, a negative pressure is generated in the receiving cavity 211 of the atomizing body 200. The circumferentially spaced protrusions 145 of the second sealing base 14 abut against the inner surface of the outer shell 20 of the atomizing body 200, creating an air gap between the inner surface of the outer shell 20 of the atomizing body 200 and the outer surface of the outer shell 10 of the reservoir 100; and this air gap is between 0.1 and 1.5 mm. During the removal of the reservoir 100, external air can enter from the first end 210 of the outer shell 20 along the air gap between the inner surface of the outer shell 20 and the outer surface of the outer shell 10 into the space between the second sealing base 14 and the sealing element 260, thereby eliminating or eliminating the negative pressure generated in the receiving cavity 211. Figure 13 As indicated by the middle arrow R12.

[0219] exist Figure 2 , Figure 10 , Figure 12 and Figure 13 In the illustrated embodiment, since the plurality of protrusions 145 are arranged circumferentially at intervals, the air gap extends from the first end 210 of the housing 20 to the space between the second sealing base 14 and the sealing element 260.

[0220] In this embodiment, the atomizing body 200 and / or the porous element 240 are not stored or adsorbed with liquid matrix before the user attaches the reservoir 100 to the atomizing body 200 or in the packaging of the electronic atomizing device. Also, in the packaging of the electronic atomizing device, only the reservoir chamber 12 of the reservoir 100 is filled with liquid matrix.

[0221] In some embodiments, the reservoir 100 may be filled or stored with approximately 2 to 10 mL of liquid matrix in its reservoir chamber 12. When all the liquid matrix in the reservoir chamber 12 of the reservoir 100 has been consumed, the user may disassemble or remove the reservoir 100 separately to replace it with a new one.

[0222] Figures 14 to 19 The diagram shows an atomizing body 200a of yet another embodiment being sold or packaged independently; in this embodiment, the atomizing body 200a includes:

[0223] The housing 20 extends from the first end 210 to the second end 220; the housing 20 has a partition wall 212 arranged vertically to the housing 20, and the partition wall 212 has a support wall 213 extending toward the first end 210; the housing 20 has a connecting portion 221 with a reduced outer diameter at the second end 220 for connection with the power supply body 300.

[0224] The sealing element 260 is located inside the housing 20 and longitudinally abuts against the partition wall 212;

[0225] A receiving cavity 211 is formed or defined between a sealing element 260 and a first end 210; the receiving cavity 211 is open at the first end 210.

[0226] A tubular retaining element 230 extends at least partially within a receiving cavity 211 for receiving and retaining a porous element 240 and a heating element 250; the retaining element 230 surrounds and is coupled to a support wall 213, and the retaining element 230 abuts longitudinally against a partition wall 212, thereby the retaining element 230 is supported and retained by the partition wall 212 and the support wall 213.

[0227] More specifically, the retaining element 230 includes a first section 231, a second section 232, and a third section 233 arranged longitudinally in sequence; the first section 231 is for insertion into the tubular element 16 of the reservoir 100, the third section 233 surrounds and is coupled to the support wall 213; the second section 232 accommodates and retains the porous element 240 and the heating element 250.

[0228] according to Figures 14 to 19 As shown, the atomizing body 200a also includes:

[0229] The sealing element 29a extends at least partially from the first end 210 of the housing 20 into the receiving cavity 211, thereby sealing the receiving cavity 211. In some embodiments, the sealing element 29a is rigid; for example, in some embodiments, the sealing element 29a may be made of rigid polymer plastic, ceramic, etc.

[0230] In this embodiment, the closure element 29a is generally configured to be tubular in shape.

[0231] In an embodiment, the sealing element 29a includes a suction nozzle portion 291a; the suction nozzle portion 291a forms or defines an air outlet 2911a; when the sealing element 29a extends into the receiving cavity 211 and longitudinally abuts against the sealing element 260, the suction nozzle portion 291a is exposed outside the receiving cavity 211.

[0232] In this embodiment, the closure element 29a further includes:

[0233] The shielding portion 292a is basically an annular sheet arranged circumferentially around the sealing element 29a; when the sealing element 29a extends into the receiving cavity 211 and longitudinally abuts against the sealing element 260, the shielding portion 292a is basically flush with the first end 210 of the receiving cavity 211, thereby the shielding portion 292a basically closes or shields the opening of the first end 210 of the receiving cavity 211.

[0234] In an embodiment, the outer diameter of the shielding portion 292a is smaller than the diameter of the opening at the first end 210 of the receiving cavity 211, thereby creating a gap between it and the housing 20, which in turn defines the air inlet 216a for air to enter the receiving cavity 211.

[0235] In this embodiment, the closure element 29a further includes:

[0236] A first extension portion 293a and a second extension portion 294a extend sequentially from the shielding portion 292a away from the nozzle portion 291a. Both the first extension portion 293a and the second extension portion 294a are hollow tubular; and the outer diameter of the first extension portion 293a is smaller than the outer diameter of the second extension portion 294a. A plurality of circumferentially spaced abutting protrusions 295a are arranged on the surface of the second extension portion 294a away from the first extension portion 293a.

[0237] When the closure element 29a extends into the receiving cavity 211, the abutment protrusion 295a longitudinally abuts against the sealing element 260 to provide a stop. The longitudinal abutment protrusion 295a abuts against the sealing element 260, resulting in a sealed connection between the closure element 29a and the sealing element 260, but with a gap. The first extension portion 293a and the second extension portion 294a are arranged around the retaining element 230 and are spaced apart from it.

[0238] In one embodiment, the atomizing body 200a further defines an airflow channel R4, providing a flow path for outside air from the air inlet 216a to the air outlet 2911a. In this embodiment, the airflow channel R4 avoids passing through the atomizing components.

[0239] Specifically, the airflow channel R4 includes:

[0240] The air intake section extends between the housing 20 and the sealing element 29a from the air intake port 216a toward the bottom surface of the sealing element 260 / receiving cavity 211;

[0241] The air outlet extends from the bottom surface of the sealing element 260 / receiving cavity 211 to the air outlet 2911a within the sealing element 29a.

[0242] In this embodiment, the air inlet and air outlet are connected by a gap formed when the abutment protrusion 295a longitudinally abuts against the sealing element 260.

[0243] In one embodiment, the vent portion extends substantially longitudinally through the closure element 29a. In another embodiment, a portion of the vent portion is formed or defined between the retaining element 230 and the closure element 29a.

[0244] In this embodiment, the outer diameter of the first extension 293a of the sealing element 29a is smaller than the inner diameter of the housing 20, so that the first extension 293a does not contact the inner surface of the housing 20. The outer diameter of the second extension 294a is substantially equal to the inner diameter of the housing 20, and thus the second extension 294a contacts the inner surface of the housing 20. A longitudinally extending notch 2941a is arranged on the second extension 294a to provide or define a portion of the air intake portion between the second extension 294a and the housing 20.

[0245] In the embodiments, according to Figure 18 As shown, when the atomizing body 200a is combined with the power supply body 300, if the user draws air into the air outlet 2911a of the mouthpiece portion 291a of the sealing element 29a, air is delivered from the air inlet 216a to the air outlet 2911a by the airflow channel R4, and essentially no airflow is formed through the power supply body 300 and / or the atomizing assembly. Therefore, during use... Figure 18 As shown, if the user draws air through the outlet 2911a of the nozzle portion 291a of the sealed element 29a, the sensor 370 will not be triggered, and consequently, the heating element 250 will not heat up. And in Figure 18 As shown, when the user draws air from the outlet 2911a of the nozzle portion 291a of the sealing element 29a, no aerosol is generated and delivered to the user from the outlet 2911a. Furthermore, in this embodiment, the nozzle portion 291a of the sealing element 29a primarily provides decorative, aesthetic, or simulation functions, rather than drawing aerosol 91a, such as a so-called "dummy nozzle".

[0246] according to Figure 19 As shown, the sealing element 29a of the atomizing body 200a can be removed from the receiving cavity 211 by the user through the exposed mouthpiece portion 291a. Figure 19 As indicated by the middle arrow P2, when the sealing element 29a is removed, the space of the receiving cavity 211 is released, and the opening of the receiving cavity 211 at the first end 210 is exposed and opened; then the user can then... Figure 11 The liquid reservoir 100 is then received from the opening of the first end 210 of the receiving cavity 211 and used within the receiving cavity 211.

[0247] Alternatively, in some other variations, the atomizing body 200 / 200a and the power supply body 300 are integrated, and therefore cannot be disassembled relative to each other. In the product sales or packaging of the electronic atomizing device, the atomizing body 200 / 200a and the power supply body 300 are securely assembled as a single unit. The liquid reservoir 100, however, is packaged separately.

[0248] 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.
