Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device and a liquid reservoir for the 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). Known electronic atomizing devices replenish the liquid matrix to a reusable body via a separate, replaceable liquid source. Summary of the Invention

[0058] 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.

[0059] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0060] Figures 1 to 3 A schematic diagram of an electronic atomizing device according to an embodiment is shown; in this embodiment, the electronic atomizing device includes a first body 100 and a second body 200; the first body 100 and the second body 200 can each exist independently, while also being combined with each other.

[0061] In one embodiment, the first body 100 can store more liquid matrix than the second body 200 for replenishing the liquid matrix during use. The second body 200 can store a relatively smaller amount of liquid matrix and atomize the liquid matrix to generate an aerosol. The first body 100 and the second body 200 exist independently of each other before being combined; and when the first body 100 is combined with the second body 200, they together define a complete electronic atomizing device for use or inhalation of an aerosol by a user. Alternatively, in some embodiments, the first body 100 is primarily used as a reservoir to store a larger amount of liquid matrix; the second body 200 defines the atomizing function for storing a relatively smaller amount of liquid matrix and atomizing it to generate an aerosol.

[0062] In some embodiments, when the first body 100 and the second body 200 exist separately or independently, they cannot be independently used or pumped by the user. For example, in Figures 1 to 4 As shown, the first body 100 at least partially defines a mouthpiece for use or inhalation by a user; the second body 200 is capable of atomizing a liquid matrix to generate an aerosol. When the first body 100 is removed or detached from the second body 200, the first body 100 cannot atomize the liquid matrix to generate an aerosol independently, and the second body 200 cannot be inhaled by the user independently.

[0063] In some embodiments, the first body 100 and the second body 200 can only be used by the user when they are combined to define a complete electronic atomizing device, and are recycled as a whole after the liquid matrix inside them is consumed. In some embodiments, once the first body 100 is combined with the second body 200 to define a complete electronic atomizing device, the first body 100 cannot be disassembled or replaced from the second body 200.

[0064] Alternatively, in some other embodiments, the first body 100 is removably attached to the second body 200; in use, the first body 100 is used as a consumable and can be replaced, while the second body 200 is reusable; when the liquid matrix in the first body 100 is consumed, the user can remove the consumed first body 100 from the second body 200 and replace it with a new first body 100.

[0065] according to Figures 1 to 7 As shown, the first body 100 has a proximal end 110 and a distal end 120 that are opposite each other in the longitudinal direction; in use, the proximal end 110 is the end that is closer to the user for suction; the distal end 120 is the end that is farther away from the user.

[0066] according to Figures 1 to 7As shown, the first body 100 includes several components disposed within a first housing 10 (which may be referred to as a housing). The overall design of the first housing 10 is variable, and the type or configuration of the first housing 10, which defines the overall size and shape of the first body 100, is also variable. Typically, the first housing 10 may be formed from a single integral housing, or the first housing 10 may be formed from two or more separable bodies. Figures 1 to 7 As shown, the first housing 10 may contain one or more reusable components; the first housing 10 is located near and defines the proximal end 110 of the first body 100; in some examples, all or only part of the first housing 10 may be formed of a metal or alloy such as stainless steel or aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, etc. The first housing 10 is open toward the distal end 120.

[0067] exist Figures 1 to 7 As shown, the first body 100 also includes a closing element 140, which is close to and defines the distal end 120 of the first body 100. Furthermore, the closing element 140 closes the opening of the first housing 10 toward the distal end 120.

[0068] exist Figures 1 to 7 As shown, the first housing 10 includes:

[0069] A first portion 11 and a second portion 12 are arranged sequentially along the longitudinal direction; when the first body 100 is attached to the second body 200, the second portion 12 is inserted into or extends into the second body 200, while the first portion 11 is located outside the second body 200. The first portion 11 and the second portion 12 have different widths or thicknesses, thereby forming or defining a step between the first portion 11 and the second portion 12; when the first body 100 is attached to the second body 200, a stop is provided by the first end 210 of the second body 200 abutting against the step between the first portion 11 and the second portion 12.

[0070] according to Figures 1 to 7 As shown, at least one or more connecting structures 121 are arranged on the outer surface of the second part 12. When the first body 100 is attached to the second body 200, the second part 12 is inserted into or extends into the second body 200, and a mechanical connection is established between the second part 12 and the second body 200 by at least one or more connecting structures 121, thereby stably attaching the first body 100 to the second body 200. Figures 1 to 7 In the embodiment shown, the connection structure 121 is, for example, a protrusion or groove located on the outer surface of the second part 12.

[0071] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0072] The air outlet 113 is located near the proximal end 110 and is used for user suction.

[0073] An aerosol output tube 111 extends from the outlet 113 toward the distal end 120 for delivering aerosol to the outlet 113; in an embodiment, the aerosol output tube 111 is integrally molded with the first housing 10.

[0074] A first liquid reservoir 112 is used to store a liquid matrix; at least a portion of the first liquid reservoir 112 is defined between the aerosol outlet tube 111 and the first housing 10. The side of the first liquid reservoir 112 near the proximal end 110 is closed, and the boundary of the first liquid reservoir 112 facing the distal end 120 is closed or defined by a sealing element 140. In use, the liquid matrix within the first liquid reservoir 112 exits from the sealing element 140. In some embodiments, the first liquid reservoir 112 is primarily defined between the first portion 11 of the first housing 10 and the aerosol outlet tube 111; and at least a portion of the first housing 10, such as the first portion 11, is transparent. Thus, the liquid matrix within the first liquid reservoir 112 is visible through the outer surface of the first portion 11 of the first housing 10.

[0075] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0076] The sealing element 140 is arranged substantially perpendicular to the longitudinal direction of the first body 100; the sealing element 140 is located at the distal end 120 of the first body 100. The sealing element 140 is close to and closes the opening of the first liquid storage chamber 112 toward the distal end 120.

[0077] according to Figures 1 to 7 As shown, the sealing element 140 is also provided with a tracheal perforation 143; after assembly, the aerosol output tube 111 extends out of the first body 100 after passing through at least part of the tracheal perforation 143, thereby facilitating connection with the second body 200.

[0078] In some embodiments, the closure element 140 is rigid, for example, made of a rigid polymer plastic. The closure element 140 is coupled to the first housing 10 by a tight fit or similar means, forming a seal between them. In this embodiment, no flexible sealing material is used to provide a seal between the closure element 140 and the first housing 10.

[0079] according to Figures 1 to 7As shown, at least one or more liquid outlet connectors 144 are arranged on the closure element 140; the at least one or more liquid outlet connectors 144 extend away from the reservoir 112. In this embodiment, the at least one or more liquid outlet connectors 144 extend toward the distal end 120 and terminate at and define the distal end 120. In this embodiment, the liquid outlet connector 144 is a hollow tubular shape. The interior of the liquid outlet connector 144 surrounds or defines a liquid outlet channel 141; the liquid outlet channel 141 is used to provide a pathway for the liquid matrix in the first reservoir 112 to leave or exit. After assembly, the liquid matrix in the first reservoir 112 can only be output or exited from the liquid outlet channel 141 in the liquid outlet connector 144 of the closure element 140.

[0080] according to Figures 1 to 7 As shown, the liquid outlet connector 144 is arranged to protrude from the first body 100 / closure element 140 at its distal end 120; or, the liquid outlet connector 144 protrudes from the distal end 120 relative to other portions of the first body 100. In this embodiment, the liquid outlet channel 141 extends substantially longitudinally along the first body 100. In this embodiment, the liquid outlet connector 144 and / or the liquid outlet channel 141 has a length of approximately 4 to 12 mm. In this embodiment, the liquid outlet channel 141 has a diameter of 1.5 to 5.0 mm. For example, in one specific embodiment, the diameter of the liquid outlet channel 141 is 1.9 mm.

[0081] according to Figures 1 to 7 As shown, the liquid outlet connector 144 has a closed free end 146; and the liquid outlet connector 144 with its closed free end 146 defines the distal end 120 of the first body 100. The liquid outlet connector 144 has an increased outer diameter or wall thickness at the free end 146. This increased outer diameter or wall thickness further defines an abutment step on the outer surface of the liquid outlet connector 144. A liquid outlet 145 is arranged on the sidewall of the liquid outlet connector 144 for the liquid matrix to flow out. In some embodiments, the diameter or width of the liquid outlet 145 can limit the outflow of a large amount of liquid matrix and ensure that the liquid matrix flows out only at a predetermined rate. In a specific embodiment, the diameter or width of the liquid outlet 145 is between 0.5 and 1.5 mm; in a more specific embodiment, the diameter or width of the liquid outlet 145 is 0.8 mm. The liquid outlet 145 is arranged close to the free end 146 of the liquid outlet connector 144.

[0082] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0083] A movable blocking element 160 is arranged around the liquid outlet connector 144; the blocking element 160 is movable relative to the liquid outlet connector 144 along the axial direction of the liquid outlet connector 144 to selectively block and close the liquid outlet 145 or expose and open the liquid outlet 145.

[0084] For example Figure 6 and Figure 7 A schematic diagram of the blocking element 160 in the open and closed positions is shown. Figure 6 In the middle, the blocking element 160 surrounds or wraps around the liquid outlet connector 144 from the outside, and blocks and closes the liquid outlet 145 to prevent the liquid matrix from being discharged from the liquid outlet 145. When the blocking element 160 moves axially along the liquid outlet connector 144 to Figure 7 When opening a location, for example Figure 7 As indicated by the middle arrow P3, the shielding element 160 avoids the liquid outlet 145, thereby exposing and opening the liquid outlet 145 to allow the liquid matrix to be discharged from the liquid outlet 145.

[0085] In some embodiments, the shielding element 160 is flexible, for example, made of a flexible silicone, thermoplastic elastomer, or other material. In some embodiments, the shielding element 160 is configured as an annular shape surrounding the liquid outlet connector 144.

[0086] according to Figures 1 to 7 As shown, the first body 100 also includes:

[0087] The elastic element 150 is used to provide an elastic force to bias the blocking element 160 toward the closed position and to stably hold the blocking element 160 in the closed position.

[0088] In one embodiment, the elastic element 150 includes a linear spring surrounding the liquid outlet connector 144. In assembly, the elastic element 150 is positioned between the closure element 140 and the blocking element 160. One end of the elastic element 150 abuts against or connects to the closure element 140, and the other end abuts against or connects to the blocking element 160. Figure 6 In this configuration, the elastic force of the elastic element 150 provides a stop by stably pressing the blocking element 160 against the step defined by the free end 146, thereby stably holding the blocking element 160 in the closed position. The elastic element 150 is actuable between an extended state and a compressed state, and biased back to the extended state; Figure 6 In the middle, when the blocking element 160 is in the closed position, the elastic element 150 is in the extended state; Figure 7 In the middle, the elastic element 150 is pressed into a compressed state.

[0089] In this embodiment, the first body 100 does not include or has no heating element or atomizing component capable of heating or atomizing the liquid matrix to generate an aerosol. Only the second body 200 is provided with a heating element or atomizing component capable of heating or atomizing the liquid matrix to generate an aerosol.

[0090] according to Figures 8 to 13 As shown, the second body 200 includes:

[0091] The first end 210 and the second end 220 are opposite to each other in the longitudinal direction;

[0092] The first side 280 and the second side 290 are opposite to each other along the width direction;

[0093] A second housing 20 extends between a first end 210 and a second end 220. The second housing 20 is open at the first end 210 of the second body 200, thereby defining a receiving cavity 211 at the first end 210 of the second body 200. When the first body 100 is attached to the second body 200, the receiving cavity 211 is used to receive a portion of the first body 100; specifically, a second portion 12 of the first housing 10 is inserted into or received within the receiving cavity 211.

[0094] according to Figures 8 to 13 As shown, the second body 200 also includes:

[0095] A support 320 is used to accommodate, support, or hold the various functional components used for liquid matrix atomization. The support 320 also divides and defines a portion of the space within the second housing 20 to form a receiving cavity 211; when the first body 100 is received within the receiving cavity 211 of the second body 200, the first body 100 is at least partially supported by the support 320. Figures 8 to 13 As shown, the support element 320 is securely connected to the second housing 20 by riveting or snap-fitting.

[0096] Specifically according to Figure 9 As shown, the bracket 320 includes:

[0097] The first support portion 3210 is arranged substantially perpendicular to the longitudinal direction of the second shell 20;

[0098] The second support portion 3220 is basically in the form of a thin sheet extending from the first support portion 3210 toward the first end 210;

[0099] The third support portion 3230 is basically arranged in a tubular shape extending from the first support portion 3210 toward the second end 220. The third support portion 3230 is open toward the second end 220.

[0100] After assembly, a receiving cavity 211 is formed by the first support portion 3210 and the second support portion 3220 and the first end 210 of the second housing 20. The second support portion 3220 is close to the second side 290; and the second support portion 3220 extends substantially straight to make the boundary of the receiving cavity 211 close to the second side 290 straight, which is advantageous for providing foolproof or prompting the user that the first body 100 can only be received in the receiving cavity 211 in a predetermined direction.

[0101] according to Figures 8 to 13 As shown, the second body 200 also includes:

[0102] Cell 240 is used for power supply;

[0103] The partition wall 250 extends longitudinally along the second housing 20; the partition wall 250 is integrally molded with the second housing 20; the partition wall 250 is located between the first support portion 3210 and the second end 220 of the bracket 320.

[0104] After assembly, the third support portion 3230 of the bracket 320 is installed and held between the partition wall 250 and the first side 280 of the second housing 20. Furthermore, the partition wall 250 isolates and defines an electronic chamber between the partition wall 250 and the second side 290 of the second housing 20; the electronic chamber is for mounting and accommodating electronic components such as the battery cell 240 and a control circuit board (not shown).

[0105] according to Figures 8 to 13 As shown, the bracket 320 defines or arranges the following:

[0106] A receiving cavity 323 is defined or formed on the first support portion 3210; and the receiving cavity 323 is arranged toward or adjacent to the receiving cavity 211; the third support portion 3230 is arranged to be longitudinally aligned with the receiving cavity 323 and is in communication with it.

[0107] A flexible sealing element 310 is housed and assembled within a receiving cavity 323. The sealing element 310 assembled within the receiving cavity 323 is annular in shape; an air tube insertion hole 311 is arranged within the sealing element 310; when the first body 100 is received within the second body 200, the aerosol output tube 111 is at least partially inserted into the air tube insertion hole 311 to form an assembly.

[0108] according to Figures 8 to 13 As shown, the bracket 320 defines or arranges the following:

[0109] The second liquid storage chamber 324 is defined by a portion of the space within the third support portion 3230; or, the second liquid storage chamber 324 is defined by a hollow portion within the third support portion 3230 of the support element 320, and the second liquid storage chamber 324 is located within the support element 320; the second liquid storage chamber 324 forms a liquid matrix storage space located within the second body 200 for storing liquid matrix;

When the flexible sealing element 310 is received and assembled in the receiving chamber 323, the sealing element 310 partially abuts axially against the support inner wall 321 to form a stop.

[0113] according to Figures 8 to 13 As shown, the annular inner support wall 321 and the tubular third support portion 3230 form or define the following:

[0114] The liquid inlet 322 extends from the receiving cavity 323 to the second liquid storage cavity 324. The sealing element 310 has a clearance hole 312 opposite to the liquid inlet 322; when the sealing element 310 is received and installed within the receiving cavity 323 of the support element 320, the clearance hole 312 is opposite to the liquid inlet 322, thereby exposing and opening the liquid inlet 322.

[0115] according to Figures 8 to 13 As shown, the bracket 320 defines or arranges the following:

[0116] A tubular element 340 is housed or held within the third support portion 3230 of the support element 320; the tubular element 340 extends axially along the third support portion 3230 of the support element 320; the tubular element 340 penetrates the liquid holding element 330; after assembly, a portion of the upper end of the tubular element 340 extends into the inner wall 321 of the support and is fixed by riveting or interference fitting. A step 327 is defined within the inner wall 321 facing the second liquid storage chamber 324; after assembly, a portion of the upper end of the tubular element 340 is inserted into the inner wall 321 of the support and abuts against the step 327.

[0117] An atomizing assembly, located within the tubular element 340 and in fluid communication with the liquid holding element 330 and / or the second liquid reservoir 324, is used to draw in a liquid matrix and atomize it to generate an aerosol; see also Figures 8 to 13 As shown, the atomizing assembly includes a liquid guiding element 350 and a heating element 360 combined with the liquid guiding element 350.

[0118] In some embodiments, the support element 320 and / or the tubular element 340 are made of rigid ceramic, stainless steel, or polymer plastic, etc.

[0119] In some embodiments, the liquid holding element 330 may be made of a rigid porous material such as porous ceramic or porous glass, or it may be made of a flexible porous fiber such as porous cotton fiber, porous nonwoven fabric or porous sponge.

[0120] In some embodiments, the liquid guiding element 350 is flexible, for example, made of flexible fibers such as cotton fibers, nonwoven fabric, or sponge; the liquid guiding element 350 is configured as a tubular or cylindrical shape arranged along the longitudinal direction of the third support portion 3230 of the support element 320; the liquid guiding element 350 is coaxial with the liquid holding element 330 and / or the tubular element 340 and is located within the liquid holding element 330 and / or the tubular element 340. Alternatively, in some other variations, the liquid guiding element 350 may also include a rigid porous element, such as porous ceramic or porous glass. The outer surface of the liquid guiding element 350 is in fluid communication with the liquid holding element 330 and / or the second liquid reservoir 324, thereby allowing the outer surface of the liquid guiding element 350 to draw liquid matrix from the liquid holding element 330 and / or the second liquid reservoir 324, such as... Figure 13 As indicated by the middle arrow R12.

[0121] In some embodiments, the liquid guiding element 350 is surrounded and held by the liquid holding element 330, and contacts the liquid holding element 330 to form fluid communication. Alternatively, in some other embodiments, the liquid guiding element 350 is held within a tubular element 340, which is provided with a plurality of liquid perforations 341; the liquid guiding element 350 draws liquid matrix from the liquid holding element 330 and / or the second liquid reservoir 324 through the liquid perforations 341 on the tubular element 340.

[0122] In some embodiments, the inner surface of the liquid guiding element 350 in the radial direction is configured as an atomizing surface, which is coupled / adhered / abutted against the heating element 360; subsequently, after the liquid matrix is ​​transferred to the atomizing surface, it is heated and atomized by the heating element 360 to generate an aerosol and released. See also Figures 8 to 13As shown, the heating element 360 is arranged to extend longitudinally along the liquid guiding element 350, and the heating element 360 is coaxially arranged with the liquid guiding element 350. In some alternative embodiments, the heating element 360 is a resistance heating mesh, resistance heating coil, etc. In this embodiment, the heating element 360 is a heating element wound from a sheet-like or mesh-like substrate. Conductive pins 361 are soldered or arranged on the heating element 360, and are electrically connected to a control circuit board through the conductive pins 361 for guiding current on the heating element 360.

[0123] In some variations, the heating element 360 may be bonded to the liquid guiding element 350 by means of printing, deposition, sintering, or physical assembly. In some other variations, the liquid guiding element 350 may have a planar or curved surface for supporting the heating element 360, which is formed on the planar or curved surface of the liquid guiding element 350 by means of mounting, printing, deposition, etc. Alternatively, in some variations, the heating element 360 is a conductive trace formed on the surface of the liquid guiding element 350. In some variations, the conductive trace of the heating element 360 may be in the form of printed lines formed by printing. In some variations, the heating element 360 is a patterned conductive trace. In some variations, the heating element 360 is planar. In some variations, the heating element 360 is a tortuous, meandering, reciprocating, or zigzag-extending conductive trace.

[0124] See Figures 8 to 13 As shown, the second body 200 also includes:

[0125] A flexible base 370 is disposed between the third support portion 3230 and the second end 220 of the bracket 320; the flexible base 370 is at least partially inserted into the third support portion 3230, thereby closing the opening of the third support portion 3230 and / or the second liquid storage chamber 324 toward the second end 220, and supporting the liquid holding element 330 and the atomizing assembly.

[0126] Specifically, the base 370 is provided with a insertion slot 372 for inserting and installing the tubular element 340; after assembly, the lower end of the tubular element 340 is inserted into the insertion slot 372 of the base 370 for installation and fixation. After assembly, the liquid holding element 330 and / or the tubular element 340 are longitudinally clamped or held between the inner support wall 321 and the base 370.

[0127] according to Figures 8 to 13 As shown, the second body 200 also includes:

[0128] An air inlet 221, located at the second end 220, is used to allow outside air to enter during suction.

[0129] The air intake passage 371, defined by the base 370, provides a flow path for delivering air entering through the air intake 221 to the atomizing assembly.

[0130] according to Figure 11 As shown, the electronic atomizing device defined when the first body 100 is attached to the second body 200 includes:

[0131] An airflow channel provides a flow path from the air inlet 221 through the atomizing assembly / heating element 360 to the air outlet 113, to output the aerosol generated by the atomizing assembly / heating element 360 to the air outlet 113. In an embodiment, the entire airflow channel is partially defined by the second body 200 and partially by the first body 100. A supporting inner wall 321 surrounds and defines a portion of the airflow channel.

[0132] Specifically, the complete airflow path during suction is as follows: Figure 8 and Figure 11 As shown by the middle arrow R2, the air entering from the air inlet 221 passes through the air intake channel 371 to the atomizing component / heating element 360, and carries the aerosol generated by the heating element 360 through the air pipe insertion hole 311 of the supporting inner wall 321 and the sealing element 310 in sequence before entering the aerosol output pipe 111, and finally output to the air outlet 113 to be inhaled by the user.

[0133] In some embodiments, the liquid holding element 330 has an upper surface and a lower surface that are opposite to each other in the axial direction. The upper surface of the liquid holding element 330 abuts against the inner support wall 321 and covers the liquid inlet interface 322. In still other embodiments, the base 370 has a plurality of protrusions extending toward the liquid holding element 330; after assembly, the lower surface of the liquid holding element 330 abuts against the protrusions, forming or defining a gap between it and the base 370.

[0134] In some embodiments, the liquid retention element 330 is defined by a single porous fiber element. Alternatively, in some further variations, the liquid retention element 330 includes a first porous fiber material layer and a second porous fiber material layer arranged sequentially in the axial direction. The first porous fiber material layer defines the upper surface of the liquid retention element 330, and the second porous fiber material layer defines the lower surface of the liquid retention element 330. The liquid retention element 330 is formed by stacking the first and second porous fiber material layers on top of each other.

[0135] In some embodiments, the second porous fiber material layer is made of a flexible capillary fiber material, such as natural cotton fiber, nonwoven fiber, etc.

[0136] In some embodiments, the first porous fiber material layer includes rayon, or rigid rayon or artificial foam made of filamentous polyurethane. For example, the first porous fiber material layer uses 138# rigid synthetic organic polymer fiber; or, for another example, the first porous fiber material layer uses 138# rigid synthetic organic polymer fiber with a density of 0.1–0.9 mg / mm². 3 The density. The first porous fiber material layer is prepared from oriented fibers arranged substantially along its length, width, or radial direction. The arrangement of the oriented fibers along the length or width of the first porous fiber material layer gives it strong bending resistance and thus a rigid texture. Specifically, for example, the first porous fiber material layer may be rigid rayon comprising oriented polyester fibers, or rigid rayon or artificial foam composed of filamentous polyurethane, etc.

[0137] according to Figures 8 to 13 As shown, after assembly, the upper surface of the liquid holding element 330 abuts against the port of the liquid inlet interface 322 defined by the support element 320 and covers the port of the liquid inlet interface 322; this prevents or avoids air in the liquid inlet interface 322 from communicating with the outside air through the gap or opening between the liquid holding element 330 and the third support portion 3230. When the liquid matrix in the second reservoir 324 is consumed, the portion of the liquid holding element 330 near the upper surface is free of liquid matrix. The porous structure in this portion provides a channel for transmitting negative pressure between the capillary channel / liquid inlet interface 322 and the second reservoir 324, so that the capillary channel / liquid inlet interface 322 can maintain balance with the negative pressure or pressure in the second reservoir 324.

[0138] according to Figure 11 and Figure 13 As shown, when the first body 100 is combined with the second body 200, the liquid output connector 144 of the sealing element 140 of the first body 100 extends into or penetrates the liquid input interface 322, thereby fluidly connecting the first liquid storage chamber 112 of the first body 100 and the second liquid storage chamber 324 of the second body 200.

[0139] according to Figure 11 and Figure 13As shown, when the first body 100 is attached to the second body 200, the liquid outlet 145 on the liquid outlet connector 144 of the sealing element 140 is located within the liquid inlet interface 322. Furthermore, the outer surface of the liquid outlet connector 144 is not in contact with the inner surface of the liquid inlet interface 322, thus defining a first distance d21 between the outer surface of the liquid outlet connector 144 and the inner surface of the liquid inlet interface 322. Also, the outer surface of the free end 146 of the liquid outlet connector 144 inserted into the liquid inlet interface 322 is defined between the inner surface of the liquid inlet interface 322. Finally, the free end 146 of the liquid outlet connector 144 inserted into the liquid inlet interface 322 is not in contact with the liquid holding element 330 located in the second liquid reservoir 324, thus defining a third distance d23 between the liquid outlet connector 144 and the liquid holding element 330.

[0140] In some embodiments, the first spacing d21 is greater than the second spacing d22. In some alternative embodiments, the first spacing d21 is approximately between 0.2 and 2.0 mm; in some alternative embodiments, the second spacing d22 and / or the third spacing d23 is approximately between 0.1 and 0.5 mm. In still other specific embodiments, the first spacing d21 is approximately 0.5 mm; the second spacing d22 and / or the third spacing d23 is 0.15 mm. Or in still other specific embodiments, the first spacing d21 is approximately 1.0 mm; the second spacing d22 and / or the third spacing d23 is 0.25 mm.

[0141] In this embodiment, a capillary channel is defined between the liquid output connector 144 and the liquid input interface 322 by a first spacing d21 and a second spacing d22. This capillary channel, defined by the first spacing d21 and the second spacing d22, adsorbs and retains the liquid matrix flowing from the liquid outlet 145 of the liquid output connector 144, thereby preventing a large amount of liquid matrix from the first reservoir 112 from being replenished to the second reservoir 324. In this embodiment, the capillary channel, defined by the first spacing d21 and the second spacing d22, allows for capillary control of replenishing the liquid matrix from the first reservoir 112 to the second reservoir 324 in a predetermined amount; this is advantageous for preventing the second reservoir 324 from becoming oversaturated with the liquid matrix.

[0142] Specifically, in use, when the amount of liquid matrix absorbed and held by the liquid holding element 330 in the second liquid storage chamber 324 is sufficient, the negative pressure or pressure in the second liquid storage chamber 324 is lower than a preset threshold. At this time, if... Figure 13As indicated by the middle arrow R11, the liquid matrix flowing out of the liquid outlet 145 of the liquid output connector 144 is adsorbed and retained within the capillary channel defined by the first spacing d21 and the second spacing d22, forming a liquid film to seal the liquid outlet 145, thereby preventing a large amount of liquid matrix from the first storage chamber 112 from being replenished to the second storage chamber 324. As the liquid matrix adsorbed and retained by the liquid holding element 330 in the second storage chamber 324 is consumed, when the negative pressure in the second storage chamber 324 exceeds a predetermined threshold, the liquid matrix retained within the capillary channel defined by the first spacing d21 and the second spacing d22 flows along the inner surface of the liquid input interface 322 into the second storage chamber 324, as shown by the negative pressure. Figure 13 As indicated by arrow R12. When a predetermined amount of liquid matrix is ​​added to the second reservoir 324, causing the negative pressure of the second reservoir 324 to fall below the predetermined threshold again, the liquid matrix flowing out from the liquid outlet 145 on the liquid output connector 144 is adsorbed in the capillary channel defined by the first spacing d21 and the second spacing d22, reaching an equilibrium and preventing further addition of liquid matrix to the second reservoir 324. Furthermore, by maintaining a capillary channel between the liquid output connector 144 and the liquid input interface 322, the first reservoir 112 can be controlled to replenish the second reservoir 324 with a predetermined amount each time, based on the user's inhalation or usage. Specifically, the electronic atomizing device can respond to the user's inhalation and automatically replenish the liquid matrix of the first body 100 to the second body 200 in a predetermined amount during each inhalation or during the lag period after inhalation.

[0143] In this embodiment, the volume of the first liquid storage chamber 112 within the first body 100 is greater than the volume of the second liquid storage chamber 324 within the second body 200. The amount of liquid matrix that the first liquid storage chamber 112 can absorb and store is greater than the amount of liquid matrix that the second liquid storage chamber 324 of the second body 200 can absorb and store. For example, in some specific embodiments, the first liquid storage chamber 112 within the first body 100 can absorb and store 5–20 mL of liquid matrix, more specifically, for example, 10 mL; the second liquid storage chamber 324 of the second body 200 can store 5–20 mL of 0.5–3 mL of liquid matrix, more specifically, for example, 2 mL.

[0144] Alternatively, in some variations, the capillary channel defined by the non-contact boundary between the outer surface of the liquid output connector 144 and the inner surface of the liquid input interface 322 can be replaced by capillary grooves on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322. In this variation, when the liquid output connector 144 is inserted into the liquid input interface 322, the outer surface of the liquid output connector 144 may abut or contact the inner surface of the liquid input interface 322, and the capillary channel is defined between them by the capillary grooves on the outer surface of the liquid output connector 144 and / or the inner surface of the liquid input interface 322.

[0145] Alternatively, in some other variations, a plurality of longitudinally extending ridges are arranged on the outer surface of the liquid output connector 144; and these ridges are spaced apart around the liquid output connector 144 in the circumferential direction. When the liquid output connector 144 is inserted into the liquid input interface 322, a capillary channel is defined between the liquid output connector 144 and the liquid input interface 322 by the gaps between the ridges.

[0146] exist Figure 11 and Figure 13 As shown, the third gap d23 defined between the liquid output connector 144 and the liquid holding element 330 can prevent the liquid matrix in the capillary channel from being directly drawn away by the porous liquid holding element 330.

[0147] In this embodiment, the diameter of the liquid outlet 145 of the liquid output connector 144 is greater than the first spacing d21; and the first spacing d21 is greater than the second spacing d22. This arrangement progressively reduces the area of ​​the channel during the liquid matrix outflow process, which is advantageous for progressively reducing the flow rate and increasing liquid retention to achieve a predetermined amount of liquid matrix supply.

[0148] according to Figures 3 to 13 As shown, the number of liquid output connectors 144 of the first body 100 may include multiples; for example, in an embodiment, the number of liquid output connectors 144 of the first body 100 is two. Furthermore, the number of liquid outlets 145 on each liquid output connector 144 may also include multiples. In use, when the liquid matrix in the first liquid storage chamber 112 flows out from at least one of the liquid outlets 145 on the multiple liquid output connectors 144, at least another liquid outlet 145 is used as an air inlet to provide air into the liquid output connector 144 and up to the first liquid storage chamber 112, in order to maintain pressure balance within the first liquid storage chamber 112.

[0149] according to Figures 3 to 13As shown, the first body 100 has at least two liquid output connectors 144, for example, the liquid output connectors 144 may include a first connector and a second connector arranged side by side; correspondingly, the second body 200 also has at least two liquid input interfaces 322, for example, the liquid input interfaces 322 may include a first interface and a second interface arranged side by side. The first connector and the second connector are respectively arranged on both sides of the atomizing assembly, and the first interface and the second interface are respectively arranged on both sides of the atomizing assembly. In some embodiments, the free ends 146 of the first connector and the free ends 146 of the second connector are flush. Furthermore, the distance between the liquid outlet 145 on the first connector and the free end 146 is equal to the distance between the liquid outlet 145 on the second connector and the free end 146.

[0150] For example, in one embodiment, each liquid output connector 144 has two liquid outlets 145 arranged on its sidewall in a radially opposite direction; when the liquid matrix in the liquid output connector 144 flows out from one of the two liquid outlets 145 into the liquid input interface 322, the air in the liquid input interface 322 enters the liquid output connector 144 from the other of the two liquid outlets 145.

[0151] according to Figures 10 to 13 As shown, during the process of the user combining the first body 100 with the second body 200, the bracket 320 drives the shielding element 160 of the first body 100 to move from the closed position to the open position, so that when the first body 100 is combined with the second body 200, the liquid outlet 145 of the liquid output connector 144 extends into the liquid input interface 322 and is exposed to form a connection.

[0152] Specifically, according to Figure 8 and Figure 9 As shown, when the sealing element 310 is received in the receiving cavity 323, the inner diameter of the clearance hole 312 of the sealing element 310 is slightly larger than the inner diameter of the liquid inlet interface 322; thus, an operating step 326 is formed between the receiving cavity 323 of the bracket 320 and the liquid inlet interface 322; when the user operates to attach the first body 100 to the second body 200, the operating step 326 blocks the blocking element 160, thereby causing the liquid outlet connector 144 to move relative to the blocking element 160 during the insertion into the liquid inlet interface 322, thereby moving the blocking element 160 from the closed position to the open position to open the liquid outlet 145. In the embodiment, the operating step 326 is partially defined by the supporting inner wall 321 and partially defined by the bottom wall of the receiving cavity 323.

[0153] During user operation, the process by which the operating step 326 blocks the blocking element 160 to cause relative movement with the liquid outlet connector 144 can be found in [reference needed]. Figures 10 to 13As shown. Wherein:

[0154] Figure 10 and Figure 11 The image shows the user operation along the edge. Figure 10 The middle arrow P11 shows a schematic diagram of one state during the process of joining the first body 100 to the second body 200; there is still a gap d11 between the first body 100 and the second body 200, thus the predetermined joining state has not been achieved. Figure 10 and Figure 11 As shown, the liquid output connector 144 only partially extends into or is inserted into the liquid input interface 322, and the blocking element 160, in the closed position, abuts against the operating step 326, thus forming a blockage. Figure 10 and Figure 11 In the shown configuration, only the free end 146 of the liquid outlet connector 144 extends into the liquid inlet interface 322. And in Figure 10 and Figure 11 As shown, the elastic element 150 is in an extended state.

[0155] Figure 12 and Figure 13 The image shows the user's operation path. Figure 12 The middle arrow P12 further points to Figure 10 The first main body 100 is pressed down, causing it to engage with the second main body 200 in a predetermined engagement state; in Figure 12 and Figure 13 As shown, if the user further presses the first body 100, the liquid output connector 144 will extend or insert further into the liquid input interface 322, while the blocking element 160 is blocked by the operating step 326 and remains within the sealing element 310. Figure 13 In the predetermined engagement state shown, the liquid outlet 145 of the liquid outlet connector 144 extends into and is exposed at the liquid inlet interface 322, thereby establishing conductivity. And in Figure 12 and Figure 13 As shown, the elastic element 150 is in a compressed state.

[0156] exist Figure 12 and Figure 13 As shown, when the first body 100 is coupled to the second body 200 in a predetermined coupling state, the blocking element 160 is blocked and thus held within the clearance hole 312 of the sealing element 310; and the annular blocking element 160 is at least partially radially compressed or squeezed by the sealing element 310 and the liquid outlet connector 144, thereby providing a seal between them.

[0157] In some embodiments, when the first body 100 is detached or removed from the second body 200 by user operation, the elastic element 150 provides a bias to move the blocking element 160 from the open position to the closed position, so that the liquid outlet 145 is closed in the removed state after the first body 100 has been removed.

[0158] 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.
