Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device. 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). 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.

[0086] 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.

[0087] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0088] Figure 1 and Figure 2 A schematic diagram of an embodiment of an electronic atomizing device is shown, including several components disposed within a housing (which may be referred to as a casing). The overall design of the casing can vary, and the type or configuration of the external body that defines the overall size and shape of the electronic atomizing device can also vary. Typically, the elongated body can be formed from a single, integral casing, or the elongated casing can be formed from two or more separable bodies.

[0089] For example, an electronic atomizing device may have a control body at one end, which has a housing containing one or more reusable components (e.g., a battery such as a rechargeable battery and / or a rechargeable supercapacitor, and various electronic devices for controlling the operation of the product).

[0090] In some embodiments, the housing of the electronic atomizing device substantially defines the outer surface of the electronic atomizing device; in Figures 1 to 2 In the specific embodiment shown, the electronic atomizing device includes:

[0091] The housing may contain one or more reusable components; the housing has a proximal end 110 and a distal end 120 opposite each other in the longitudinal direction; in use, the proximal end 110 is the end closer to the user for suction; the distal end 120 is the end further away from the user;

[0092] In some examples, the housing may be formed wholly or partially from metals or alloys such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plated overplastic, ceramics, and so on.

[0093] In some embodiments, the housing is formed by several components. Figure 1 and Figure 2 In the illustrated embodiment, the housing includes:

[0094] A first housing 11 and a second housing 12 are joined longitudinally; wherein the first housing 11 is adjacent to or defines the proximal end 110, and the second housing 12 is adjacent to or defines the distal end 120.

[0095] according to Figures 3 to 20 As shown, to facilitate modular production and assembly of the electronic atomizing device, the electronic atomizing device in this embodiment includes a first module 130 and a second module 140. In production, the first module 130 and the second module 140 are first assembled separately, and then they are joined longitudinally to form a complete electronic atomizing device. After assembly, the first module 130 is positioned near or defines the proximal end 110, and the second module 140 is positioned near or defines the distal end 120.

[0096] In this embodiment, the second module 140 of the electronic atomizing device 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 air outlet 111 for the user to inhale.

[0097] In some embodiments, after the first module 130 and the second module 140 are longitudinally combined to assemble a complete electronic atomizing device, 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 electronic atomizing device; 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.

[0098] according to Figures 3 to 20 As shown, the second module 140 includes:

[0099] The second housing 12 has an upper end 1210 opposite to the distal end 120; the second housing 12 is open at the upper end 1210.

[0100] The container 20 is basically cylindrical, at least partially located within the second housing 12, and surrounds and defines a liquid storage cavity 201 for storing a liquid matrix.

[0101] An electronic chamber is formed or defined between the liquid reservoir 201 and the distal end 120; the electronic chamber houses and contains electronic components such as a battery cell 125 for power supply and a circuit board (not shown).

[0102] In one embodiment, the electronic chamber is isolated from the reservoir 201; specifically, the container 20 has a partition wall 210 arranged substantially perpendicular to the longitudinal direction of the electronic atomizing device; this partition wall 210 is located between the reservoir 201 and the electronic chamber, and provides isolation between the reservoir 201 and the electronic chamber. Alternatively, the electronic chamber is formed or defined between the partition wall 210 and the distal end 120.

[0103] In this embodiment, the side of the liquid storage chamber 201 facing the distal end 120 is closed and defined by the partition wall 210 of the container 20.

[0104] In some embodiments, the container 20 is transparent, for example, made of transparent plastic. The second housing 12 is provided with at least one or more windows 121 through which at least a portion of the container 20 is visible. Thus, in use, the remaining amount of liquid matrix in the reservoir 201 within the container 20 can be viewed through the windows 121.

[0105] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0106] A charging interface 122, such as a type-C interface, is located between the battery cell 125 and the remote end 120 for charging the battery cell 125.

[0107] The cell holder 126 is located inside the electronic chamber and is used to house and retain the cell 125.

[0108] In an embodiment, the cell retainer 126 is made of a rigid material such as plastic, ceramic, or metal. In an embodiment, the cell retainer 126 is generally L-shaped. In an embodiment, a portion of the cell retainer 126 surrounds the cell 125 from its outer periphery, and a portion is located between the cell 125 and the distal end 120, thereby providing retention for the cell 125 both longitudinally and peripherally.

[0109] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0110] A flexible first buffer element 128 is located between the cell 125 and the partition wall 210 to provide flexible buffering between them to protect the cell 125.

[0111] A flexible second buffer element 129 is located between the cell 125 and the cell retainer 126 to provide flexible buffering between them to protect the cell 125.

[0112] In the embodiments, the first buffer element 128 and / or the second buffer element 129 are made of flexible silicone, elastomer or polyurethane foam, etc.

[0113] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0114] An airflow sensor 127 is located within the electronic chamber and is securely held to the partition wall 210. Specifically, a mounting groove may be arranged on the surface of the partition wall 210 facing the electronic chamber, and the airflow sensor 127 is accommodated within the mounting groove. The airflow sensor 127 is used to sense changes in airflow through the electronic atomizing device during user inhalation. The airflow sensor 127 is connected to a circuit board via conductive leads.

[0115] according to Figures 3 to 20 As shown, a portion of the container 20 extends beyond the upper end 1210 of the second housing 12. Furthermore, a connecting groove 123 is defined between the container 20 and the second housing 12, and the connecting groove 123 is open at the upper end 1210 for connecting the first housing 11 to the second housing 12 after insertion.

[0116] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0117] A sealing element 42 is attached to the container 20 and seals the liquid storage chamber 201. The sealing element 42 is at least partially located between the liquid storage chamber 201 and the atomizing assembly 30, separating and isolating the two components. Alternatively, the side of the liquid storage chamber 201 facing away from the partition wall 210 is sealed by the sealing element 42. In embodiments, the sealing element 42 is made of a rigid material such as plastic or ceramic.

[0118] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0119] The capillary element 52 extends from the liquid reservoir 201 into the enclosed element 42. In some embodiments, the capillary element 52 is flexible, for example, made of a flexible capillary fiber material such as cotton fiber or nonwoven fiber; or in other embodiments, the capillary element 52 is rigid, for example, made of a rigid porous ceramic body, porous glass, etc.

[0120] In one embodiment, the capillary element 52 is used to transfer the liquid matrix in the reservoir 201 toward the proximal end 110 to the atomizing assembly 30. In another embodiment, the capillary element 52 is arranged along the longitudinal central axis of the electronic atomizing device.

[0121] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0122] A rigid tubular element 51 is longitudinally mounted and held between the closure element 42 and the partition wall 210. The tubular element 51 may be made of, for example, a rigid metal or ceramic, and more specifically, for example, stainless steel. The tubular element 51 is arranged around a portion of the capillary element 52 to support and hold the capillary element 52 within the reservoir 201.

[0123] In this embodiment, the tubular element 51 is a mesh-like tube with several perforations or slits 511 on its wall. The liquid matrix in the storage chamber 201 passes through the perforations or slits 511 and is drawn in by the capillary element 52, and then transferred via the capillary element 52 to the atomizing assembly 30 for atomization, for example... Figures 3 to 20 As indicated by the middle arrow R1.

[0124] exist Figures 3 to 20 In the illustrated embodiment, the tubular element 51 and the partition wall 210 are manufactured separately and then assembled. The partition wall 210 has a generally annular insertion portion 211 extending toward the proximal end 110; after assembly, one end of the tubular element 51 is inserted into the insertion portion 211 and secured. The other end of the tubular element 51 is inserted into the closing element 42.

[0125] Alternatively, in some other variations, the tubular element 51 may be integrally molded with the partition wall 210; then, after fabrication, the tubular element 51 is integrally and securely connected to the partition wall 210.

[0126] In some embodiments, the capillary element 52 has a diameter d52 of about 4 to 10 mm; and the capillary element 52 has a length of about 30 to 60 mm.

[0127] In some embodiments, the tubular element 51 has a wall thickness of approximately 0.1 to 1.0 mm; and the tubular element 51 has a length of approximately 20 to 40 mm.

[0128] according to Figures 3 to 20 As shown, the capillary element 52 may include a first segment 521 and a second segment 522 arranged in the longitudinal direction; wherein the first segment 521 is closer to the proximal end 110.

[0129] After assembly, the second section 522 is accommodated and held within the tubular element 51; or, the second section 522 is located within the reservoir 201. The first section 521 extends out of the tubular element 51 and / or the reservoir 201; and the first section 521 extends into the closure element 42 and is thereby surrounded by the closure element 42.

[0130] In this embodiment, the length of the second segment 522 is equal to the length of the tubular element 51, approximately 20 to 40 mm; the length of the first segment 521 is approximately 10 to 20 mm.

[0131] according to Figures 3 to 20 As shown, after assembly, a gap d21 of, for example, 0.2 to 2.0 mm, exists between the sealing element 42 and the outer surface of the first section 521, thus preventing the outer surface of the first section 521 from being completely covered by the sealing element 42; and an air cavity 43, at least partially surrounding the first section 521, is defined between the sealing element 42 and the outer surface of the first section 521 by the gap d21. The air cavity 43 at least partially surrounds the first section 521 and is in air communication with the airflow channel through the electronic atomizing device; when the user inhales, the negative pressure of the airflow channel can be transmitted to the air cavity 43, thereby generating a differential negative pressure on the outside of the first section 521, promoting the wetting and transfer of the liquid matrix from the second section 522 to the first section 521.

[0132] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0133] The flexible first sealing element 41 is made of, for example, a flexible silicone material, and at least partially covers the surface of the closure element 42 facing the proximal end 110; and the first sealing element 41 is at least partially located between the closure element 42 and the container 20, thereby providing a seal between them.

[0134] according to Figures 12 to 17 As shown, there is a positioning mechanism between the closure element 42 and the first sealing element 41, such as a positioning protrusion 427 on the closure element 42 and a hole on the first sealing element 41 into which the positioning protrusion 427 is inserted; during assembly, the positioning protrusion 427 is inserted into the hole of the first sealing element 41 to provide positioning.

[0135] according to Figures 12 to 17 As shown, the closing element 42 also defines:

[0136] At least one or more support walls 421 are provided with steps 423; the support walls 421 are for mounting and holding the atomizing assembly 30. After assembly, an air cavity 43 is formed by the at least one or more support walls 421 surrounding the first segment 521 of the capillary element 52 and defining the gap between them. When the atomizing assembly 30 is mounted and held within the at least one or more support walls 421, the atomizing assembly 30 is closer to the proximal end 110 than the liquid reservoir 201; and the atomizing assembly 30 contacts and abuts against the first segment 521 of the capillary element 52 to form a liquid guide, thereby indirectly drawing liquid matrix from the first segment 521 of the capillary element 52 from the liquid reservoir 201.

[0137] according to Figures 12 to 17 As shown, the first sealing element 41 is provided with:

[0138] The basic feature is an annular flange 411; after assembly, at least one or more support walls 421 of the sealing element 42 extend into or insert into the annular flange 411. When the first module 130 and the second module 140 are assembled into a complete electronic atomizing device, the flange 411 provides at least partially a seal between the at least one or more support walls 421 of the sealing element 42 and the first module 130.

[0139] according to Figure 13 As shown, at least one or more support walls 421 are not closed in the circumferential direction surrounding the atomizing assembly 30. Thus, when the atomizing assembly 30 is received and assembled within the at least one or more support walls 421, an air gap 431 is formed between the atomizing assembly 30 and the flange 411, defined by the unclosed positions between adjacent support walls 421; and this air gap 431 provides air communication between the air cavity 43 and the airflow channel / atomizing chamber. This allows the negative pressure within the airflow channel to be conducted to the air cavity 43 via the air gap 431 during inhalation. Alternatively, at least a portion of the outer surface of the first segment 521 of the capillary element 52 is in air communication with the airflow channel / atomizing chamber through the air gap 431. In some embodiments, the width of the air gap 431 is approximately 1 to 3 mm.

[0140] according to Figures 12 to 17 As shown, the enclosing element 42 is also provided with:

[0141] At least one or more clamping walls 422 are arranged around the support wall 421; and the clamping walls 422 are spaced apart from the support wall 421 and have a gap 424. Correspondingly, the first sealing element 41 is provided with a clearance hole 414 for the clamping walls 422 to pass through.

[0142] After assembly, at least one or more clamping walls 422 are arranged around the protrusion 411 of the first sealing element 41 and clamp the protrusion 411 of the first sealing element 41 between the clamping walls 422 and the support wall 421, which is advantageous for preventing the protrusion 411 from being pulled outward and bent during the assembly of the sealing element 42 and the first sealing element 41.

[0143] according to Figures 3 to 20 As shown, the second module 140 also includes:

[0144] The atomizing assembly 30 is configured to indirectly draw a liquid matrix from the first segment 521 of the capillary element 52 originating from the reservoir 201 and atomize the liquid matrix to generate an aerosol. In an embodiment, the atomizing assembly 30 includes a porous element 31 and a heating element 32. In another embodiment, the atomizing assembly 30 further includes a holding element 33 for receiving and holding the porous element 31.

[0145] In the embodiments, the porous element 31 may include flexible porous fiber elements such as cotton fibers, non-woven fibers, and sponges, or it may also include rigid porous elements such as porous ceramic bodies, porous glass, or foam metal.

[0146] In some embodiments, the heating element 32 is prepared from a sheet of resistive metal by cutting or etching. For example, the heating element 32 is prepared from a resistive metal such as an iron-chromium-aluminum alloy or a nickel-chromium alloy. In some embodiments, the heating element 32 and the porous element 31 are prepared independently and then assembled together; or in some embodiments, the heating element 32 is prepared on the surface of the porous element 31 and combined with the porous element 31 by deposition, printing, or other methods.

[0147] In this embodiment, the atomizing component 30 is arranged substantially perpendicular to the longitudinal direction of the electronic atomizing device. In this embodiment, the atomizing component 30 is substantially block-shaped.

[0148] In one embodiment, the porous element 31 has a length of approximately 6–12 mm, a width of 3–6 mm, and a thickness of approximately 2–4 mm. Correspondingly, the substantially planar heating element 32 has a length of approximately 6–12 mm and a width of 3–6 mm.

[0149] In this embodiment, the porous element 31 is substantially longitudinally positioned to abut and contact the first segment 521 of the capillary element 52, thereby indirectly drawing in the liquid matrix originating from the reservoir 201. Specifically, the porous element 31 is substantially sheet-like, having a first surface and a second surface facing away from each other; the first surface of the porous element 31 is arranged toward the proximal end 110 and is configured as an atomizing surface; a heating element 32 is at least partially attached to the first surface of the porous element 31 for heating at least a portion of the liquid matrix within the porous element 31 to generate an aerosol. The second surface of the porous element 31 is arranged toward the distal end 120 and is configured as a liquid-absorbing surface for abutting and contacting the first segment 521 of the capillary element 52 to draw in the liquid matrix.

[0150] In some embodiments, the first and / or second surfaces of the porous element 31 are flat planes. Alternatively, in some other embodiments, the first and / or second surfaces are curved surfaces. Or, in still other embodiments, the heating element 32 is a planar heating element.

[0151] In this embodiment, the retaining element 33 is generally configured in the shape of a frame or bracket. Furthermore, the retaining element 33 has a receiving hole 331 extending longitudinally through it, the receiving hole 331 being adapted to the shape of the porous element 31. The porous element 31 is then received within the receiving hole 331 and subsequently housed within the retaining element 33.

[0152] In this embodiment, the heating element 32 includes:

[0153] A first electrical connection portion 321, a second electrical connection portion 323, and a heating portion 322 located between the first electrical connection portion 321 and the second electrical connection portion 323. The first electrical connection portion 321 and the second electrical connection portion 323 define the electrical connection area of ​​the heating element 32, and the heating portion 322 defines the heating area of ​​the heating element 32.

[0154] In this embodiment, the heating portion 322 is substantially planar.

[0155] In one embodiment, the heating portion 322 is arranged in a mesh shape; or in another embodiment, the heating portion 322 may be configured as a meandering conductive trajectory or conductive pattern. Or in yet another variation of the embodiment, the heating portion 322 may also have more shapes, such as a wave shape, a spiral shape, a U-shape, etc.

[0156] After assembly, the heating portion 322 of the heating element 32 is at least partially attached to the surface of the retaining element 33 facing the proximal end 110.

[0157] In one embodiment, the heating portion 322 has a first tooth 3221 extending to one side in the width direction and a second tooth 3222 extending to the other side in the width direction. Specifically, the first tooth 3221 extends from the mesh portion of the heating portion 322 to one side, and the second tooth 3222 extends from the mesh portion of the heating portion 322 to the other side. After assembly, the mesh-like heating portion 322 crosses the receiving hole 331 of the frame or frame-shaped retaining element 33 in the width direction. Furthermore, after assembly, both the first tooth 3221 and the second tooth 3222 are at least partially engaged with the frame or frame-shaped retaining element 33, which is advantageous for promoting fixation.

[0158] In this embodiment, when current is guided onto the heating portion 322 through the first electrical connection portion 321 and the second electrical connection portion 323, essentially no current flows through the first tooth portion 3221 and the second tooth portion 3222; therefore, the first tooth portion 3221 and the second tooth portion 3222 are essentially non-heated areas of the heating element 32. The heat-generating area of ​​the heating portion 322 is defined by the mesh portion located between the first tooth portion 3221 and the second tooth portion 3222.

[0159] In one embodiment, a positioning mechanism is further provided between the holding element 33 and the heating element 32 to provide positioning during the assembly of the atomizing assembly 30 and to prevent relative movement of the holding element 33 and the heating element 32 in the length and width directions of the atomizing assembly 30. In a specific embodiment, the positioning mechanism includes:

[0160] At least one or more positioning protrusions 332 are arranged on the surface of the retaining element 33 facing the proximal end 110;

[0161] At least one or more positioning holes 325 are arranged in the first electrical connection portion 321 and / or the second electrical connection portion 323 of the heating element 32 for a positioning protrusion 332 to extend into. After assembly, the positioning protrusion 332 extends into the positioning hole 325 to provide positioning.

[0162] according to Figures 12 to 17 As shown, the first electrical connection portion 321 also has a first hook portion 3211 bent from one side of the atomizing assembly 30 to the other side, and the second electrical connection portion 323 also has a second hook portion 3231 bent from one side of the atomizing assembly 30 to the other side; during assembly, the first hook portion 3211 and / or the second hook portion 3231 abut against and engage with the second surface of the retaining element 33 / porous element 31, thereby keeping them connected.

[0163] according to Figures 12 to 17As shown, a defined clamping opening 324 is surrounded within the first hook portion 3211 and / or the second hook portion 3231; the retaining element 33 is at least partially located within the clamping opening 324.

[0164] according to Figures 12 to 17 As shown, when the atomizing assembly 30 is installed and assembled within the support wall 421 of the enclosing element 42, the first hook portion 3211 of the first electrical connection portion 321 and the second hook portion 3231 of the second electrical connection portion 323 longitudinally abut against the step 423. The surfaces of the first electrical connection portion 321 and / or the second electrical connection portion 323 facing the proximal end 110 can be soldered with conductive leads, thereby connecting the first electrical connection portion 321 and / or the second electrical connection portion 323 to the circuit board of the electronic chamber. Specifically, for example, a first conductive lead (not shown) can be connected to the first electrical connection portion 321, and a second conductive lead (not shown) can be connected to the second electrical connection portion 323.

[0165] according to Figure 12 As shown, in the embodiment, the support wall 421 of the sealing element 42 and / or the protruding edge 411 of the first sealing element 41 are provided with lead grooves for the first conductive lead and / or the second conductive lead to pass through, and after assembly, the lead grooves provide restriction and retention for the first conductive lead and / or the second conductive lead, so as to facilitate the installation and fixation of the first conductive lead and / or the second conductive lead. Specifically in Figures 12 to 17 As shown, a first lead groove 412 is arranged on the protrusion 411 of the first sealing element 41, and a first conductive lead and / or a second conductive lead extends out of the protrusion 411 after passing through the first lead groove 412. Additionally, a second lead groove 413 is also provided on the surface of the first sealing element 41 facing the proximal end 110, and the first conductive lead and / or the second conductive lead extending out of the protrusion 411 extends from within the second lead groove 413 to the space between the first sealing element 41 and the container 20.

[0166] according to Figure 12 As shown, a third lead groove 230 is also arranged on the outer surface of the container 20. The first conductive lead and / or the second conductive lead extending from the second lead groove 413 enter the third lead groove 230, and then pass through the third lead groove 230 of the container 20 to enter the electronic cavity and connect with the circuit board.

[0167] In some embodiments, the first conductive lead and / or the second conductive lead are at least partially confined and fixed within the first lead groove 412 and / or the second lead groove 413 on the first sealing element 41.

[0168] In some embodiments, the first conductive lead and / or the second conductive lead are at least partially confined between the container 20 and the second housing 12; specifically, they are confined within the third lead groove 230 of the container 20. In some embodiments, the first conductive lead and / or the second conductive lead are at least partially longitudinally bypassing the container 20 and / or the liquid storage chamber 201 before connecting to a circuit board inside the electronic chamber.

[0169] Alternatively, in some embodiments, the first conductive lead and / or the second conductive lead passes through the container 20 and / or the reservoir 201. For example, in some optional embodiments, the container 20 and / or the reservoir 201 are provided with lead through-holes extending longitudinally along the direction of the electronic atomizing device, the lead through-holes being defined by a longitudinally extending tubular wall within the container 20 and / or the reservoir 201. After assembly, the first conductive lead and / or the second conductive lead pass through the lead through-holes defined by the tubular wall and connect to a circuit board within the electronic chamber.

[0170] root Figures 3 to 8 , Figures 12 to 20 As shown, the second module 140 also includes:

[0171] The sensing channel 221 is at least partially defined by a tubular wall 220 extending longitudinally within the reservoir 201. In an embodiment, the tubular wall 220 is integrally molded with the container 20.

[0172] In the use of the electronic atomizing device, the airflow sensor 127 is connected to the airflow channel through the sensing channel 221, thereby enabling the airflow sensor 127 to sense changes in the airflow flowing through the electronic atomizing device when the user inhales. Furthermore, the circuit board controls the battery cell 125 to output power to the atomizing assembly 30 / heating element 32 based on the sensing results of the airflow sensor 127.

[0173] In an embodiment, the sensing channel 221 is at least partially located within the container 20; and the sensing channel 221 extends substantially longitudinally through the liquid storage chamber 201; and the sensing channel 221 is isolated from the liquid storage chamber 201 by a tubular wall 220.

[0174] root Figures 3 to 8 , Figures 12 to 20 As shown, after the atomizing assembly 30 is assembled, the capillary element 52 and the porous element 31 are substantially perpendicular. Furthermore, the first segment 521 of the capillary element 52 extends at least partially into the retaining element 33 and abuts against the liquid-absorbing surface of the porous element 31. Also, after assembly, the capillary element 52 is at least partially compressed and squeezed, which is advantageous for maintaining liquid transfer between the first segment 521 of the capillary element 52 and the porous element 31.

[0175] Alternatively, in some other embodiments, the capillary element 52 is arranged at an angle relative to the longitudinal direction of the electronic atomizing device. After assembly, the capillary element 52 and the porous element 31 have an angle of inclination of less than 90°.

[0176] Alternatively, in some variations, the first segment 521 of the capillary element 52 is non-contact with the liquid-absorbing surface of the porous element 31, and the liquid matrix is ​​adsorbed and transferred from the capillary element 52 to the porous element 31 through capillary action formed by capillary gaps or capillary spacing. For example, in some embodiments, there is a capillary gap or capillary spacing of approximately 0.2 to 1.5 mm between the first segment 521 of the capillary element 52 and the liquid-absorbing surface of the porous element 31.

[0177] according to Figure 20 As shown, the diameter d52 of the capillary element 52 is larger than the width of the heating element 32 / heating portion 322, so that a portion of the capillary element 52 is located outside the width of the heating portion 322 along the width direction of the heating portion 322. Alternatively, a portion of the projection of the capillary element 52 along the longitudinal direction of the electronic atomizing device 100 onto the plane containing the heating portion 322 is located outside the heating portion 322.

[0178] according to Figure 20 As shown, the diameter d52 of the capillary element 52 is larger than the length d322 of the heating portion 322; in some embodiments, the length of the heating portion 322 is approximately between 3 and 8 mm. The projection of the capillary element 52 along the longitudinal direction of the electronic atomizing device 100 onto the plane containing the heating portion 322 completely covers the heating portion 322, which is advantageous for ensuring sufficient delivery of the liquid matrix to the heating portion 322 for atomization.

[0179] Alternatively, in some other embodiments, the ratio of the area of ​​the capillary element 52 projected along the longitudinal direction of the electronic atomizing device 100 onto the plane containing the heating portion 322 within the heating portion 322 to the total area of ​​the heating portion 322 is greater than 0.6. More preferably, the ratio is greater than 0.8. Or more specifically, the ratio is 1.0, i.e. Figure 20 The projection of the capillary element 52 onto the plane where the heating part 322 is located completely covers the heating part 32.

[0180] In some embodiments, the ratio of the diameter of the capillary element 52 to the length dimension d322 of the heating portion 322 is greater than 0.7.

[0181] according to Figure 20 As shown, the diameter d52 of the capillary element 52 is smaller than the length of the heating element 32, and therefore the capillary element 52 does not protrude beyond the length of the heating element 32 along the length direction of the heating element 32.

[0182] In the embodiment, the diameter d52 of the capillary element 52 is smaller than the length of the heating element 32, but larger than the length dimension d322 of the heating portion 322.

[0183] according to Figures 2 to 11 As shown, the first module 130 includes:

[0184] A first housing 11 defines an outlet 111 located at a proximal end 110; the outlet 111 is used to output aerosol. The first housing 11 is open at the end opposite to the proximal end 110, and the other end of the first housing 11 opposite to the proximal end 110 has a connecting portion 115, on which at least one or more first connecting structures 116, such as connecting holes, are arranged. When the first module 130 and the second module 140 are longitudinally joined, the connecting portion 115 of the first housing 11 is inserted into the connecting groove 123 defined between the container 20 of the second module 140 and the second housing 12, and the first connecting structure 116 engages with a second connecting structure on the second module 140, such as a latch, to securely connect the first module 130 and the second module 140.

[0185] according to Figures 2 to 11 As shown, the first module 130 also includes:

[0186] The clamping element 14 is assembled and housed within the first housing 11; in the embodiment, the clamping element 14 is made of flexible silicone, thermoplastic elastomer, etc.

[0187] When the first module 130 and the second module 140 are combined, the clamping element 14 is longitudinally pressed against the atomizing component 30, and the clamping element 14 and the sealing element 42 together stably hold the atomizing component 30 between them.

[0188] Specifically, after assembly, the clamping element 14 engages or abuts against the first side of the atomizing assembly 30 facing the proximal end 110, and the support wall 421 engages or abuts against the second side of the atomizing assembly 30 away from the first side, thereby longitudinally clamping or holding the atomizing assembly 30 between the clamping element 14 and the support wall 421 of the sealing element 42.

[0189] In this embodiment, the clamping element 14 clamps the atomizing assembly 30 by abutting against the heating element 32. Specifically, in this embodiment, the clamping element 14 abuts against the edge of the heating element 32. Specifically, after assembly, the clamping element 14 at least partially abuts against the first tooth 3221 and the second tooth 3222 of the heating portion 322 of the heating element 32 to clamp the heating element 32. In use, the clamping element 14 can prevent the heating portion 322 of the heating element 32 from deforming or bending towards the proximal end 110 during heating, thereby preventing the heating portion 322 of the heating element 32 from separating from the atomizing surface of the porous element 31, which is beneficial for reducing the dry burning of the heating portion 322.

[0190] In some embodiments, the clamping element 14 may also simultaneously abut against the first electrical connection portion 321 and the second electrical connection portion 323 of the heating element 32 to clamp the heating element 32. After assembly, the clamping element 14 avoids the grid-like heating area of ​​the heating portion 322 of the heating element 32.

[0191] exist Figures 2 to 11 In the illustrated embodiment, the clamping element 14 is configured as a block arranged vertically to the electronic atomizing device.

[0192] exist Figures 2 to 11 In the embodiment shown, the clamping element 14 and the heating element 32 are further defined by:

[0193] Atomizing chamber 141 is provided to provide space for the release of aerosols generated by heating element 32. In an embodiment, heating element 32 is fluid-permeable, so that aerosols generated by heating on the atomizing surface of porous element 31 pass through heating element 32 and are released into atomizing chamber 141.

[0194] In this embodiment, the atomizing chamber 141 is primarily defined by a recess on the surface of the clamping element 14 facing the heating element 32. After assembly, the atomizing chamber 141 located between the clamping element 14 and the heating element 32 is defined by the recess on the surface of the clamping element 14 facing the heating element 32.

[0195] according to Figure 7 , Figure 8 and Figure 10 As shown, the height dimension d12 of the atomizing chamber 141 in the longitudinal direction of the electronic atomizing device is approximately between 0.1 and 3.0 mm; Figure 7 and Figure 8 As shown, the height dimension d12 of the atomizing chamber 141 in the longitudinal direction of the electronic atomizing device is basically constant. In a specific embodiment, the height dimension d12 of the atomizing chamber 141 in the longitudinal direction of the electronic atomizing device is approximately between 0.2 and 2.0 mm.

[0196] In this embodiment, the atomizing chamber 141 is substantially flat. The length of the atomizing chamber 141, defined by the cavity on the surface of the clamping element 14 facing the heating element 32, is greater than its width, and its width is greater than its height d12.

[0197] In an embodiment, the width of the atomizing chamber 141 is less than or equal to the width of the atomizing assembly 30; thus, after assembly, at least a portion of the clamping element 14 is longitudinally abutted against the support wall 421 of the enclosing element 42, thereby providing support and blocking for the clamping element 14 to prevent the flexible clamping element 14 from moving toward the atomizing assembly 30 to compress the atomizing chamber 141 or the assembly from being compressed to cause it to adhere to the heating element 32.

[0198] exist Figures 2 to 11 In the embodiment shown, the first module 130 further includes:

[0199] A bracket 13, located within the first housing 11, surrounds and encloses the clamping element 14 circumferentially, thereby at least partially accommodating and retaining the clamping element 14. In this embodiment, the bracket 13 is rigid; the bracket 13 may be made of materials such as plastic or ceramic. Specifically, an assembly cavity 132 is arranged on the surface of the bracket 13 facing the open end of the first housing 11, within which the clamping element 14 is accommodated and mounted.

[0200] according to Figure 9 , Figure 10 and Figure 11 As shown, the outer surface of the bracket 13 is provided with at least one or more positioning protrusions 135; correspondingly, the inner surface of the first housing 11 is provided with a groove adapted to the positioning protrusions 135. After assembly, the positioning protrusions 135 of the bracket 13 extend into the grooves on the inner surface of the first housing 11 to provide positioning during the assembly of the bracket 13 and the first housing 11. Furthermore, after assembly, the positioning protrusions 135 extending into the grooves on the inner surface of the first housing 11 connect the bracket 13 and the first housing 11 and prevent relative rotation between the bracket 13 and the first housing 11.

[0201] exist Figures 2 to 11 In the embodiment shown, the first module 130 further includes:

[0202] A flexible second sealing element 15 is located within the first housing 11 and between the bracket 13 and the open end of the first housing 11. After assembly, the second sealing element 15 at least partially abuts against the clamping element 14 longitudinally, thereby preventing the clamping element 14 from detaching and falling out of the assembly cavity 132 of the bracket 13 along the longitudinal direction of the electronic atomizing device.

[0203] In this embodiment, there is a gap between the second sealing element 15 and the open end of the first housing 11.

[0204] In this embodiment, the second sealing element 15 and the bracket 13 are securely connected. Specifically Figures 9 to 11 As shown, the second sealing element 15 is provided with at least one or more connection holes 154, and the bracket 13 is provided with at least one or more pins 137 that are inserted into the connection holes 154; after assembly, the second sealing element 15 and the bracket 13 abut against each other longitudinally and are connected and secured by the cooperation of the pins 137 and the connection holes 154.

[0205] In this embodiment, the second sealing element 15 is annular in shape with a clearance hole 153. After the first module 130 and the second module 140 are assembled, the support wall 421 of the sealing element 42 and the protruding edge 411 of the first sealing element 41 extend into the second sealing element 15 through the clearance hole 153, thereby positioning the atomizing assembly 30 opposite the clamping element 14 and defining the atomizing chamber 141. Furthermore, a plurality of abutting protrusions 157 are arranged on the inner surface of the clearance hole 153 of the second sealing element 15; the plurality of abutting protrusions 157 are arranged circumferentially spaced along the clearance hole 153. After assembly, the abutting protrusions 157 longitudinally abut against the clamping element 14 to prevent the clamping element 14 from falling out of the assembly cavity 132 of the bracket 13.

[0206] After assembly, at least a portion of the first sealing element 41 and the second sealing element 15 are in contact; thus, the first sealing element 41 and the second sealing element 15 provide a seal between the closing element 42 and the bracket 13. Also after assembly, at least a portion of the first conductive lead and / or the second conductive lead is confined and held between the first sealing element 41 and the second sealing element 15.

[0207] exist Figures 2 to 11 In the embodiment shown, the first module 130 further includes:

[0208] An air inlet 114 is located on the surface of the first housing 11 for allowing air to enter;

[0209] The air intake channel provides a path for air to enter the atomizing chamber 141.

[0211] The first air inlet groove 131 formed or arranged on the bracket 13 is aligned with and connected to the air inlet 114;

[0212] The second air inlet groove 142 is located on the clamping element 14; the second air inlet groove 142 is in communication with the atomizing chamber 141; after assembly, the second air inlet groove 142 provides air communication between the atomizing chamber 141 and the first air inlet groove 131 of the bracket 13.

[0213] In this embodiment, the air intake channel is defined by the first air intake groove 131 on the bracket 13 and the second air intake groove 142 on the clamping element 14, thereby allowing air from the air intake 114 to enter the atomizing chamber 141, such as... Figures 7 to 8 As indicated by the middle arrow R2.

[0214] In one embodiment, a first air intake groove 131 on the bracket 13 is formed on the surface of the bracket 13 facing the second sealing element 15; after assembly, the first air intake groove 131 is covered by the second sealing element 15. Alternatively, in another embodiment, at least a portion of the air intake passage is formed or defined between the bracket 13 and the second sealing element 15.

[0215] In one embodiment, the second air inlet groove 142 is in the form of a notch or recess on the surface of the clamping element 14. In another embodiment, the second air inlet groove 142 is offset from the heating element 32 / atomizing assembly 30 in the longitudinal direction of the electronic atomizing device. Specifically, after assembly... Figure 7 and Figure 8 As shown, in the longitudinal direction of the electronic atomizing device, the second air inlet groove 142 is opposite to the support wall 421 of the sealing element 42 and the protruding edge 411 of the first sealing element 41.

[0216] In this embodiment, at least a portion of the cross-sectional area of ​​the air intake passage is variable. Figure 7 and Figure 8 As shown, the height of the first air inlet groove 131 on the bracket 13 varies along the longitudinal direction of the electronic atomizing device; specifically, at least a portion of the height of the first air inlet groove 131 increases along the direction approaching the atomizing chamber 141. Figure 7 and Figure 8 As shown, the height d11 of the second air inlet groove 142 in the longitudinal direction of the electronic atomizing device varies; specifically, at least a portion of the height d11 of the second air inlet groove 142 decreases along the direction close to the atomizing chamber 141, which is advantageous for promoting the convergence of airflow toward the heating element 32. In this embodiment, the second air inlet groove 142 is conical.

[0217] In one embodiment, at least a portion of the cross-sectional area of ​​the air intake passage first increases and then decreases along the direction approaching the atomizing chamber 141.

[0218] In some embodiments, the height d11 of the second air inlet groove 142 in the longitudinal direction of the electronic atomizing device is greater than the height d12 of the atomizing chamber 141 in the longitudinal direction of the electronic atomizing device. In some embodiments, the ratio of the maximum value of the height d11 of the second air inlet groove 142 to the height d12 of the atomizing chamber 141 is between 1.2 and 3.0.

[0219] exist Figures 2 to 11In the illustrated embodiment, the air intake channel, defined by the first air intake groove 131 of the bracket 13 and the second air intake groove 142 of the clamping element 14, extends substantially straight. Specifically, the air intake channel extends substantially perpendicular to the longitudinal direction of the electronic atomizing device. For example, in Figures 2 to 11 As shown, the air intake channel extends substantially straight along the radial direction of the electronic atomizing device from the air intake 114 to the atomizing chamber 141. In this embodiment, the air intake 114 is aligned with the second air intake slot 142 of the clamping element 14.

[0220] exist Figures 2 to 11 In the illustrated embodiment, a sensing connector 152 is also disposed on the second sealing element 15; the sensing connector 152 protrudes from the open end of the second sealing element 15 toward the first housing 11. After assembly, the sensing connector 152 extends into or is inserted into the tubular wall 220 defining the sensing channel 221 within the container 20 of the second module 140, thereby connecting the sensing channel 221 and the air intake channel so that the airflow sensor 127 can sense changes in airflow during user inhalation.

[0221] according to Figure 7 and Figure 8 As shown, after assembly, the sensing channel 221 is arranged perpendicular to the air intake channel. In this embodiment, the sensing channel 221 is relatively closer to the air intake 114 and further away from the atomizing chamber 141. Specifically, for example in... Figure 7 As shown, the distance d31 between the sensing channel 221 and the air inlet 114 is approximately 1 to 4 mm.

[0222] exist Figures 2 to 11 In the embodiment shown, the first module 130 further includes:

[0223] The aerosol output channel 112 is used to output the aerosol in the atomizing chamber 141 to the air outlet 111. In this embodiment, both the support 13 and the clamping element 14 are annular in shape. The aerosol in the atomizing chamber 141 passes sequentially through the annular central hole of the clamping element 14 and the annular central hole of the support 13 before entering the aerosol output channel 112.

[0224] In some embodiments, the aerosol output channel 112 is defined by a portion of the first housing 11. Furthermore, the aerosol output channel 112 extends from the outlet 111 toward the distal end 120.

[0225] In this embodiment, the electronic atomizing device may have:

[0226] An airflow channel defines the airflow path from the air inlet 114 through the atomizing chamber 141 / heating element to the air outlet 111, so as to deliver the aerosol to the air outlet 111.

[0227] In an embodiment, the airflow channel may include an intake portion and an output portion; wherein, the intake portion is used to allow air to enter the atomizing chamber 141 from the intake port 114; and the output portion is used to output aerosol from the atomizing chamber 141 to the outlet port 111. The intake portion may include an intake channel defined by the first intake groove 131 of the support 13 and the second intake groove 142 of the clamping element 14; the output portion may include a path formed by the annular central hole of the clamping element 14, the annular central hole of the support 13, and the aerosol output channel 112. In some embodiments, the intake and output portions of the airflow channel are substantially perpendicular.

[0228] In this embodiment, the aerosol output channel 112 is substantially aligned with or directly connected to the heating element 32. Furthermore, the aerosol output channel 112 / outlet 111 and the heating element 32 are substantially arranged along the longitudinal central axis of the electronic atomizing device. Therefore, the projection of the outlet 111 along the longitudinal direction of the electronic atomizing device 100 onto the plane containing the heating element 32 is substantially entirely within the heating portion 322.

[0229] In the embodiments, according to Figure 6 As shown, along the longitudinal direction of the electronic atomizing device 100, the distance d4 between the air outlet 111 and the heating element 32 is less than 45 mm, which is advantageous for promoting rapid aerosol output and reducing the large amount of condensate generated during the output process. In some more preferred embodiments, the distance d4 between the air outlet 111 and the heating element 32 is less than 35 mm; for example, in some specific embodiments, the distance d4 between the air outlet 111 and the heating element 32 can be 20-30 mm; more specifically, for example, the distance d4 between the air outlet 111 and the heating element 32 is 25 mm.

[0230] Alternatively, in some variations, the aerosol output channel 112 is arranged off-center from the longitudinal central axis of the electronic atomizing device. In such variations, the aerosol output channel 112 and the heating element 32 are staggered longitudinally in the electronic atomizing device.

[0231] according to Figures 9 to 13 As indicated by the middle arrow R3, the electronic atomizing device also defines the following:

[0232] A ventilation channel is provided to connect the atomizing chamber 141 and the liquid storage chamber 201 with air, thereby balancing the pressure between the liquid storage chamber 201 and the outside. Specifically, as the negative pressure in the liquid storage chamber 201 gradually increases due to the consumption of the liquid matrix, air can enter the liquid storage chamber 201 through the ventilation channel to alleviate and balance the negative pressure in the liquid storage chamber 201.

[0233] In this embodiment, the complete path of the ventilation channel is defined by multiple components; specifically, the ventilation channel includes:

[0234] A first ventilation groove 143 is formed on the surface of the clamping element 41 facing the heating element 32; and the first ventilation groove 143 extends from the atomizing chamber 141 to the edge of the clamping element 41 in the width direction, and the first ventilation groove 143 communicates with the atomizing chamber 141; and after assembly, it extends to the inner surface of the mounting cavity 132 of the bracket 13.

[0235] The second ventilation groove 1391 is formed on the bracket 13 and is in air communication with the first ventilation groove 143, which extends to the inner surface of the assembly cavity 132 after assembly.

[0236] A ventilation compartment 1393 is formed on the surface of the bracket 13 facing the second sealing element 15 and communicates with the second ventilation groove 1391; or, the second ventilation groove 1391 extends from the inner surface of the mounting cavity 132 of the bracket 13 into the ventilation compartment 1393.

[0237] The first ventilation port 138 is defined by the bracket 13 and is connected to the ventilation compartment 1393 through the connecting hole 1392;

[0238] The second vent 158 ​​is arranged on the second sealing element 15; after assembly, the second vent 158 ​​is aligned with and connected to the first vent 138.

[0239] The third vent 418 is arranged on the first sealing element 41; when the first module 130 and the second module 140 are assembled, the third vent 418 and the second vent 158 ​​are aligned and connected.

[0240] The third ventilation groove 428 is formed on the sealing element 42 and extends through the liquid storage chamber 201; the third ventilation groove 428 is aligned with and connected to the third ventilation hole 418.

[0241] according to Figures 9 to 13 As indicated by the middle arrow R3, when the negative pressure in the liquid storage chamber 201 exceeds a predetermined threshold, the air in the atomizing chamber 141 enters the second ventilation groove 1391 of the bracket 13 through the first ventilation groove 143 of the clamping element 41, and then enters the first ventilation hole 138 through the ventilation compartment 1393 and the connecting hole 1392. It then passes through the second ventilation hole 158 of the second sealing element 15, the third ventilation hole 418 of the first sealing element 41, and the third ventilation groove 428 of the sealing element 42 in sequence to enter the liquid storage chamber 201, thereby relieving or regulating the pressure of the liquid storage chamber 201.

[0242] In this embodiment, it is formed or arranged between the proximal end 110 and the reservoir 201; more specifically, in this embodiment, the complete path of the ventilation channel is tortuous. Furthermore, the ventilation channel bypasses or crosses the atomizing chamber 141 / atomizing assembly 30.

[0243] In one embodiment, a portion of the ventilation passage is formed or defined between the second sealing element 15 and the support 13. In another embodiment, a portion of the ventilation passage is formed between the sealing element 42 and the first sealing element 41. In yet another embodiment, the ventilation passage extends longitudinally through the sealing element 42.

[0244] according to Figures 3 to 10 As shown, the first module 130 also includes:

[0245] The porous absorption element 12 is located longitudinally between the support 13 and the first housing 11.

[0246] In this embodiment, the absorber element 12 may be made of flexible fibrous materials such as fiber cotton, sponge, or silk fiber. In this embodiment, the absorber element 12 is flexible. After assembly, the absorber element 12 is used to absorb aerosol condensate from the output portion of the airflow channel.

[0247] In an embodiment, the absorbent element 12 is at least partially housed and surrounded by the support 13. Furthermore, a collection groove 136 is arranged on the surface of the support 13 facing the proximal end 110; when the absorbent element 12 is mounted within the support 13, the collection groove 136 is covered by the absorbent element 12; thus, in use, the collection groove 136 can be used to receive and collect excess condensate adsorbed within the absorbent element 12.

[0248] according to Figures 3 to 10 As shown, the bracket 13 is defined by:

[0249] At least one or more condensate guiding channels 133 are provided for guiding or directing condensate from the atomizing chamber 141 and / or the airflow channel to the absorption element 12.

[0250] In one embodiment, the condensate guiding channel 133 is in the form of a through-hole passing through the bracket 13. Also, in another embodiment, the condensate guiding channel 133 extends from the inner top wall of the assembly cavity 132 to the surface of the bracket 13 facing the proximal end 110. Figure 7 As shown, the condensate guiding channel 133 is bent.

[0251] exist Figure 7 , 10 and Figure 11 As shown, the port of the condensate guiding channel 133 on the inner top wall of the assembly cavity 132 is in the form of a groove to avoid being blocked or blocked by the clamping element 41 housed in the assembly cavity 132.

[0252] exist Figure 9 As shown, a groove 134 is arranged on the surface of the support 13 facing the proximal end 110. Figure 9The groove 134 is annular. The port of the condensate guide channel 133 on the surface of the support 13 facing the proximal end 110 is located within the groove 134.

[0253] according to Figures 4 to 10 As shown, the first housing 11 also has a flange 117 extending longitudinally from the aerosol output channel 112 toward the distal end 120. Figures 4 to 10 As shown, the convex edge 117 is annular in shape. And,

[0254] After assembly, the flange 117 is inserted into the absorber element 12, and the absorber element 12 is arranged at least partially around the flange 117.

[0255] After assembly, the flange 117 does not abut against the surface of the bracket 13 facing the proximal end 110. Figure 7 As shown, the protruding edge 117 and the surface of the support 13 facing the proximal end 110 have capillary gaps, for example, about 0.1 to 1.0 mm; and the aerosol condensate that falls from the inner surface of the aerosol output channel 112 onto the protruding edge 117 is adsorbed and transferred to the absorption element 12 for absorption by the capillary adsorption effect of the capillary gap.

[0256] Furthermore, during use, on the one hand, the liquid or condensate mixed in the aerosol during user suction can be guided to the absorption element 12 for adsorption via the condensate guiding channel 133. On the other hand, the condensate falling from the inner surface of the aerosol output channel 112 under the action of gravity can be transferred to the absorption element 12 for absorption through the capillary gap between the protrusion 117 and the support 13, so as to minimize the risk of the outlet 111 receiving condensate.

[0257] For example in Figure 10 In the embodiment shown, a plurality of radially extending capillary grooves 118 are arranged on the surface of the protrusion 117 toward the free end of the distal end 120, which is advantageous for enhancing capillary force.

[0258] 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.
