Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and in particular to an atomization body and an electronic atomization device. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning articles by creating products that release compounds without combustion.

For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing products, such as so-called electronic atomization devices. These devices typically include a liquid storage chamber to store a liquid, which is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or fragrances and / or aerosol-generating substances (e.g., glycerol). Known electronic atomization devices connect the liquid storage chamber to the external atmosphere through a straight or straight ventilation channel, which is easily blocked by liquid entry.

[0068] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0069] The present application proposes an electronic atomization device for atomizing a liquid matrix to generate an aerosol.

[0070] Figures 1 to 7 A schematic diagram of an electronic atomization device according to an embodiment is shown; in this embodiment, the electronic atomization device includes a reusable power supply body and at least two atomization bodies such as atomization body 200 and atomization body 300 that can be replaced as consumables.

[0071] In an embodiment, the power supply body defines the external structure or external surface of the electronic atomization device; at least two atomization bodies, such as atomization body 200 and atomization body 300, are completely received in the power supply body for use. In an embodiment, after the at least two atomization bodies, such as atomization body 200 and atomization body 300, are received in the power supply body by a user, the electronic atomization device is defined or formed into a usable state for the user to inhale.

[0072] In an embodiment, an atomizing body, such as atomizing body 200 and atomizing body 300, stores a liquid matrix and includes an atomizing assembly to atomize the liquid matrix to generate an aerosol. In an embodiment, a power supply body is used to control the supply of power to the atomizing body, such as atomizing body 200 and atomizing body 300, when the atomizing body is received in the power supply body, so that the atomizing body generates an aerosol.

[0073] In the embodiment, the power supply body defines a mouthpiece 111 for the user to inhale, and the user inhales during use. The atomizing body, such as the atomizing body 200 and the atomizing body 300, does not have a mouthpiece for the user to inhale.

[0074] In embodiments, when the atomizer bodies, such as atomizer body 200 and atomizer body 300, are detached from the power supply body or separated from each other and exist independently, the power supply body and the atomizer body cannot independently generate aerosol for user inhalation. In some embodiments, the power supply body and the atomizer body can only be used by the user when they are combined into a complete electronic atomization device, and can be removed and replaced when the liquid matrix inside the atomizer body is consumed.

[0075] Alternatively, in some alternative embodiments, once the atomizer body is combined with the power supply body to define a complete electronic atomization device, the atomizer body cannot be removed or replaced from the power supply body. Thus, the power supply body and the atomizer body can only be used by the user when they are combined to define a complete electronic atomization device. After the liquid matrix inside the atomizer body is consumed, it and the power supply body are discarded or recycled as a whole.

[0076] according to Figures 1 to 7 As shown, the power supply body has a proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end close to the user for suction; the distal end 120 is the end away from the user.

[0077] according to Figures 1 to 7 As shown, the power supply body includes several components disposed within a housing (which may be referred to as a shell). The overall design of the shell may vary, and the type or configuration of the shell that may define the overall size and shape of the power supply body may vary. Generally, the shell may be formed from a single, integral shell, or the shell may be formed from two or more separable bodies. Figures 1 to 7 As shown, the housing can include one or more reusable components; in some examples, all or only a portion of the housing can be formed from a metal or alloy such as stainless steel, aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, and the like.

[0078] according to Figures 1 to 7 As shown, the outer shell of the power supply body is constructed in a flat shape. Specifically, the longitudinal length of the outer shell is greater than the width, and the width is greater than the thickness. The power supply body also includes: a first side 130 and a second side 140 that are opposite to each other in the width direction; and a front side 150 and a rear side 160 that are opposite to each other in the thickness direction.

[0079] according to Figures 1 to 7 As shown, the housing of the power supply body includes:

[0080] The first housing 11 and the second housing 12 are connected in the longitudinal direction of the power supply body; the first housing 11 is close to or defines a proximal end 110, and the second housing 12 is close to or defines a distal end 120. In an embodiment, the first housing 11 can be detached or removed from the second housing 12.

[0081] according to Figures 1 to 7As shown, the second housing 12 has an upper end 1210 facing away from the distal end 120; the upper end 1210 of the second housing 12 is open. After assembly, the first housing 11 is at least partially inserted or extended into the second housing 12 to connect with the second housing 12. Specifically, the first housing 11 is provided with at least one elastic latching protrusion 113; the inner surface of the second housing 12 is provided with at least one latching groove adapted to the latching protrusion 113; when the first housing 11 is at least partially inserted or extended into the second housing 12, a mechanical connection is established by the latching protrusion 113 extending into the latching groove of the inner surface of the second housing 12. The latching protrusion 113 is located at the first side 130 and / or the second side 140.

[0082] For example Figures 3 to 7 As shown in FIG. 2, when the first housing 11 is detached or removed from the second housing 12, the atomization body, such as the atomization body 200 and the atomization body 300, is at least partially exposed or revealed outside the upper end 1210 of the second housing 12, so that the user can hold the exposed part of the atomization body, such as the atomization body 200 and the atomization body 300, to operate, thereby detaching or replacing the atomization body, such as the atomization body 200 and the atomization body 300, for example Figure 4 As shown by the arrow in FIG. 2, when the first housing 11 is combined with the second housing 12, the exposed part of the atomization body, such as the atomization body 200 and the atomization body 300, exposed outside the upper end 1210 of the second housing 12 is covered or surrounded by the first housing 11.

[0083] When the atomization body 200 and the atomization body 300 are received in the power supply body, the atomization body 200 and the atomization body 300 are symmetrical along the longitudinal central axis of the power supply body. Alternatively, the atomization body 200 and the atomization body 300 have rotational symmetry of 180 degrees around the longitudinal central axis of the power supply body. When the atomization body 200 and the atomization body 300 are received in the power supply body, the atomization body 200 and the atomization body 300 are arranged spaced apart in the width direction of the power supply body. Specifically, the atomization body 200 is located between the longitudinal central axis of the power supply body and the first side 130, so that the atomization body 200 is closer to the first side 130 than the atomization body 300; the atomization body 300 is located between the longitudinal central axis of the power supply body and the second side 140, so that the atomization body 300 is closer to the second side 140 than the atomization body 200.

[0084] According to Figures 1 to 7 As shown in FIG. 1, the first housing 11 defines or is provided with a suction port 111 for the user to draw; and the suction port 111 defines an air outlet 112 at the proximal end 110 for outputting aerosol. The suction port 111 is convex relative to the first housing 11 at the proximal end 110. The suction port 111 is arranged offset from the longitudinal central axis of the power supply body.

[0085] According to Figure 5 、 Figures 8 to 11 As shown, the nozzle 111 can be operated by a user to move between a first position and a second position. Figure 5 In the figure, the suction nozzle 111 is located in the first position; Figure 11 , the suction nozzle 111 is located at the second position.

[0086] In the first position, the mouthpiece 111 is in airflow communication with the atomizing body 200; the user can inhale the aerosol produced by the atomizing body 200 through the air outlet 112. In the second position, the mouthpiece 111 is in airflow communication with the atomizing body 300; the user can inhale the aerosol produced by the atomizing body 300 through the air outlet 112.

[0087] In the first position, the suction nozzle 111 is disconnected from the atomizing body 300 in air flow. In the second position, the suction nozzle 111 is disconnected from the atomizing body 200 in air flow.

[0088] In the first position, the suction nozzle 111 is close to the first side 130 ; in the second position, the suction nozzle 111 is close to the second side 140 .

[0089] according to Figure 5 、 Figures 8 to 11 As shown, the suction nozzle 111 can rotate around the longitudinal center axis of the power supply body, thereby moving between a first position and a second position.

[0090] according to Figure 5 、 Figures 8 to 11 As shown, the suction nozzle 111 can also be operated by the user to change between the locked state and the unlocked state. The suction nozzle 111 is prevented from moving between the first position and the second position when in the locked state. The suction nozzle 111 is allowed to move between the first position and the second position when in the unlocked state.

[0091] For example Figure 8 and Figure 9 Schematic diagram showing a user unlocking the suction nozzle 111 located at the first position from a locked state through operation; Figure 8 and Figure 9 As shown by the middle arrow P11, the user pulls the nozzle 111 to disengage the nozzle 111 from the holding cavity 118 of the first shell 11, thereby forming an unlocked state of the nozzle 111. Figure 5 In the locked state shown, the nozzle 111 is at least partially located within the retaining cavity 118 and is restricted by the retaining cavity 118 so as to be unable to move or rotate.

[0092] according to Figure 10 As shown by the middle arrow P12 , in the unlocked state, the user rotates the suction nozzle 111 to move the suction nozzle 111 from the first position to the second position. Figure 11The schematic diagram shows the nozzle 111 being rotated to the second position. Figure 11 The middle suction nozzle 111 is connected to the atomizing body 300. Accordingly, in the unlocked state, the user can also operate the suction nozzle 111 to rotate, so that the suction nozzle 111 can be rotated from Figure 11 The second position shown in FIG is moved to Figure 5 First position shown.

[0093] according to Figure 5 、 Figures 8 to 11 As shown, during the operation of moving and unlocking the suction nozzle 111, the suction nozzle 111 cannot be disassembled or separated from the first housing 11. During the operation of moving and unlocking the suction nozzle 111, the suction nozzle 111 and the first housing 11 remain connected.

[0094] according to Figure 5 、 Figures 8 to 11 As shown, the suction nozzle 111 is connected to the first housing 11 via a pin 115. In this embodiment, the pin 115 and the first housing 11 are connected via a countersunk screw. This prevents the suction nozzle 111 from separating from the first housing 11 during movement and unlocking operations. In this embodiment, the pin 115 is arranged substantially along the longitudinal center axis of the power supply body.

[0095] according to Figure 5 、 Figures 8 to 11 As shown, the power supply entity also includes:

[0096] The elastic element 117 is used to provide an elastic force to bias the suction nozzle 111 toward the locked state; alternatively, after the user releases the operation on the suction nozzle 111 in the first position or the second position, the elastic element 117 can provide an elastic force to drive the suction nozzle 111 from the unlocked state to the locked state.

[0097] For example, Figure 11 In the embodiment, when the suction nozzle 111 is manually rotated to the second position by the user, the user stops pulling or holding the suction nozzle 111, and the elastic element 117 provides elastic force to drive the suction nozzle 111 to at least partially extend into or move into the retaining cavity 118, thereby locking it.

[0098] In an embodiment, the elastic element 117 is linearly elastic and is arranged around the pin 115 .

[0099] according to Figure 5 、 Figures 8 to 11 As shown, an aerosol output tube 114 is arranged in the mouthpiece 111 and extends from the air outlet 112 away from the proximal end 110. In the first position, the aerosol output tube 114 connects the air outlet 112 to the atomizing body 200 in airflow communication. In the second position, the aerosol output tube 114 connects the air outlet 112 to the atomizing body 300 in airflow communication.

[0100] According to Figure 5 , Figures 8 to 11 , the first shell 11 is further provided with:

[0101] A flexible sealing element 15 is made of flexible material such as silica gel; when the suction nozzle 111 is in the first position, the sealing element 15 is located between the aerosol outlet pipe 114 and the first shell 11 to provide airtight sealing for the gap therebetween.

[0102] A flexible sealing element 16 is made of flexible material such as silica gel; when the suction nozzle 111 is in the second position, the sealing element 16 is located between the aerosol outlet pipe 114 and the first shell 11 to provide airtight sealing for the gap therebetween.

[0109] In embodiments, the first elastic body 129 and the second elastic body 128 are located between the first partition wall 126 and the second partition wall 127. The electric core 170 is elastically retained between the first elastic body 129 and the second elastic body 128. After assembly, the first elastic body 129 is located between the circuit board 180 and the electric core 170.

[0218] According to Figures 1 to 15As shown, the second housing 12 of the power supply body is provided with at least one or more first windows 122, which are arranged near or located on the first side 130. The second housing 12 is provided with at least one or more second windows 123, which are arranged near or located on the second side 140.

[0219] When the atomizing body 200 is received in the power supply body, the user can observe the remaining amount of liquid substrate in the container 321 of the atomizing body 200 located in the first receiving cavity 131 through the first window 122. Furthermore, when the atomizing body 300 is received in the power supply body, the user can observe the remaining amount of liquid substrate in the container 321 of the atomizing body 300 located in the second receiving cavity 141 through the second window 123.

[0220] according to Figures 16 to 27 As shown, the container 321 is adjacent to and defines the second end 320. The container 321 is open toward the first end 310.

[0221] according to Figures 16 to 27 As shown, the reservoir 32 also includes:

[0222] The connector element 322 is coupled to the opening of the container 321 toward the first end 310. In some embodiments, the connector element 322 at least partially extends into the container 321 and is tightly connected to the container 321 by riveting, interference fit, or the like. A flexible sealing element 328, such as an O-ring, is disposed between the connector element 322 and the inner wall of the container 321 to provide a seal therebetween.

[0223] according to Figures 16 to 27 As shown, the connector element 322 is provided or arranged with at least two liquid output connectors; specifically, the connector element 322 is arranged with:

[0224] The first liquid output joint 323 and the second liquid output joint 324 are arranged at intervals; the first liquid output joint 323 and the second liquid output joint 324 are arranged at intervals along the thickness direction of the atomizing body 200 / the atomizing body 300.

[0225] After assembly, the first liquid output connector 323 and the second liquid output connector 324 are inserted into the atomizer 31 to replenish the liquid matrix in the container 321 and / or the second liquid storage chamber 329 into the first liquid storage chamber of the atomizer 31 .

[0226] according to Figures 16 to 27As shown, the first liquid output connector 323 and the second liquid output connector 324 are arranged to extend longitudinally. Furthermore, the first liquid output connector 323 and the second liquid output connector 324 are arranged to extend away from the container. The first liquid output connector 323 and the second liquid output connector 324 are protruding. The first liquid output connector 323 and the second liquid output connector 324 have exposed free ends for insertion into the atomizer 31. The first liquid output connector 323 and the second liquid output connector 324 extend to the same length.

[0227] according to Figures 16 to 27 As shown, the connector element 322 is also provided with a first connecting structure, such as a connecting hook 325; and the end cap 34 of the atomizer 31 is provided with a second connecting structure, such as a connecting slot 347. When the liquid reservoir 32 and the atomizer 31 are assembled, the first connecting structure, such as the connecting hook 325, cooperates with the second connecting structure, such as the connecting slot 347, to establish a mechanical connection between the liquid reservoir 32 and the atomizer 31. Furthermore, once the liquid reservoir 32 and the atomizer 31 are assembled, the connection between the first connecting structure and the second connecting structure is non-detachable or releasable. Therefore, during use, once the atomizer 31 and the liquid reservoir 32 are assembled, they cannot be disassembled or separated by the user.

[0228] In an embodiment, the first connection structure, such as the connection hook 325 , is located before the first liquid output connector 323 and the second liquid output connector 324 .

[0229] according to Figures 16 to 27 As shown, the atomizer 31 is provided with:

[0230] First liquid input interface 343 and second liquid input interface 344. When the liquid reservoir 32 and the nebulizer 31 are assembled, the first liquid output connector 323 is inserted into the nebulizer 31 via the first liquid input interface 343, establishing a first liquid transfer channel connecting the second liquid storage chamber 329 to the first liquid storage chamber of the nebulizer 31. The second liquid input interface 344 is inserted into the nebulizer 31 via the second liquid input interface 344, establishing a second liquid transfer channel connecting the second liquid storage chamber 329 to the first liquid storage chamber of the nebulizer 31. During use, the liquid matrix in the second liquid storage chamber 329 is replenished to the first liquid storage chamber of the nebulizer 31 via the first liquid transfer channel and / or the second liquid transfer channel.

[0231] In an embodiment, when the atomizing body 200 / atomizing body 300 is received within the power supply body, the first liquid output connector 323 / first liquid delivery channel and the second liquid output connector 324 / second liquid delivery channel are spaced apart along the thickness direction. For example, the first liquid output connector 323 / first liquid delivery channel is located between the second liquid output connector 324 / second liquid delivery channel and the front side 150; and the second liquid output connector 324 / second liquid delivery channel is located between the first liquid output connector 323 / first liquid delivery channel and the rear side 160. Alternatively, the first liquid output connector 323 / first liquid delivery channel is relatively closer to the front side 150, while the second liquid output connector 324 / second liquid delivery channel is relatively closer to the rear side 160.

[0232] according to Figures 16 to 27 As shown, the second sealing base 35 of the atomizer 31 is provided with a first joint avoidance hole 353 and a second joint avoidance hole 354. The first joint avoidance hole 353 is aligned with the first liquid input interface 343, and the second joint avoidance hole 354 is aligned with the second liquid input interface 344. After the liquid reservoir 32 and the atomizer 31 are assembled, the first liquid output joint 323 passes through the first joint avoidance hole 353 of the second sealing base 35, extends into the first liquid storage cavity, and abuts against the lower surface of the first liquid retaining element 316. The second liquid output joint 324 passes through the second joint avoidance hole 354 of the second sealing base 35, extends into the first liquid storage cavity, and abuts against the lower surface of the first liquid retaining element 316.

[0233] In an embodiment, the distal end 120 and / or the first side 130 and / or the second side 140 of the power supply body and / or the electronic atomization device are configured to be arc-shaped; and at least a portion of the surface of the front side 150 and the rear side 160 of the power supply body and / or the electronic atomization device is flat; thus, the power supply body and / or the electronic atomization device cannot be placed vertically on a horizontal surface but can only be placed horizontally on the horizontal surface. After the atomization body 200 / atomization body 300 is received in the power supply body, the electronic atomization device can only be placed horizontally on a horizontal surface, for example Figure 28 shown.

[0234] In use, when the power supply body and / or the electronic atomization device is placed horizontally on a horizontal surface, one of the front side 150 and the rear side 160 faces upward and the other faces downward. Figure 28 In the horizontal orientation shown, the front side 150 faces upward and the rear side 160 faces downward.

[0235] In use, when the power supply body and / or the electronic atomization device is placed horizontally, one of the first liquid output connector 323 and the second liquid output connector 324 of the atomization body 200 / atomization body 300 transfers the liquid matrix while the other provides a channel for air exchange. Figure 28 As shown, when the power supply body and / or the electronic atomization device is placed horizontally on a horizontal surface, the liquid matrix in the second liquid storage chamber 329 of the atomization body 200 / atomization body 300 can be replenished with the liquid matrix to the first liquid storage chamber of the atomizer 31 via the first liquid output connector 323 / first liquid delivery channel near the rear side 160, as shown in FIG. Figure 28 As shown by the arrow R51. Figure 28 As shown by the middle arrow R52, when the liquid matrix in the second liquid storage chamber 329 is replenished into the first liquid storage chamber of the atomizer 31, the air in the first liquid storage chamber of the atomizer 31 can enter the second liquid storage chamber 329 via the second liquid output connector 324 / the second liquid transfer channel, so as to exchange air between the first liquid storage chamber and the second liquid storage chamber 329 of the atomizer 31 to balance the pressure therebetween.

[0236] according to Figures 16 to 27 As shown, the atomizing body 200 / atomizing body 300 further includes:

[0237] At least one first capillary element 326, located in the first liquid output connector 323 / first liquid delivery channel;

[0238] At least one first capillary element 327 is located in the second liquid output connector 324 / the second liquid delivery channel.

[0239] In some embodiments, the first capillary element 326 and / or the first capillary element 327 are made of a flexible natural capillary fiber material, such as a flexible natural cotton fiber or a natural non-woven fabric fiber.

[0240] Alternatively, in some other embodiments, the first capillary element 326 and / or the first capillary element 327 are made of an artificial capillary fiber material, such as a hard polyester fiber, or a hard filamentous polyurethane fiber or an artificial foam. The first capillary element 326 and / or the first capillary element 327 made of the artificial capillary fiber material has a hardness between that of natural plant cotton / non-woven fabric (Shore hardness less than 20A) and that of rigid porous ceramic / microporous metal (Shore hardness greater than 80A). Thus, the structure is stable and exhibits extremely low expansion after absorbing and soaking in a liquid matrix. Therefore, after assembly, the first capillary element 326 and / or the first capillary element 327 can more stably contact and abut against the inner wall of the first liquid output connector 323 / the second liquid output connector 324, thereby preventing the first capillary element 326 and / or the first capillary element 327 from moving within the first liquid output connector 323 / the second liquid output connector 324 after assembly. In an embodiment, the density of the first capillary element 326 and / or the first capillary element 327 made of artificial capillary fiber material is greater than the density of natural plant cotton / non-woven fiber; the first capillary element 326 and / or the first capillary element 327 with relatively large density has relatively greater ability and efficiency in adsorbing and transferring liquid matrix than natural plant cotton / non-woven fiber.

[0241] During use, the first capillary element 326 and the first capillary element 327 can absorb and buffer the liquid matrix through capillary action to adjust the flow rate of the liquid matrix delivered from the second liquid storage chamber 329 to the first liquid storage chamber; they can prevent leakage caused by excessive flow when replenishing the liquid matrix, and release the liquid matrix when the flow is slow to ensure the supply rate.

[0242] according to Figures 16 to 27 As shown, the first capillary element 326 is flush with the free end of the first liquid output connector 323; the first capillary element 327 is flush with the free end of the second liquid output connector 324. After assembly, the first capillary elements 326 and 327 abut against the underside surface of the first liquid retaining element 316, thereby being in fluid communication with the first liquid retaining element 316.

[0243] In an embodiment, the density of the first capillary element 326 and / or the first capillary element 327 made of artificial capillary fiber material is greater than the density of the first liquid retaining element 316 .

[0244] according to Figures 16 to 27 As shown, a second capillary element 383 and a second capillary element 384 are further arranged in the first liquid retaining element 316 of the atomizer 31 .

[0245] according to Figures 16 to 27As shown, the first liquid retaining element 316 has a first receiving hole 3163 and a second receiving hole 3164 extending from the upper surface to the lower surface. The second capillary element 383 is received and retained in the first receiving hole 3163. The second capillary element 384 is received and retained in the second receiving hole 3164.

[0246] In an embodiment, the second capillary element 383 and / or the second capillary element 384 are made of an artificial capillary fiber material, for example, the second capillary element 383 and / or the second capillary element 384 are made of a hard artificial cotton of polyester fiber, or a hard artificial cotton or artificial foam of filamentous polyurethane. The second capillary element 383 and / or the second capillary element 384 of the above artificial capillary fiber material has a hardness between that of a common natural plant cotton / non-woven fabric (Shore hardness less than 20A) and a rigid porous ceramic / microporous metal (Shore hardness greater than 80A). In an embodiment, the density of the second capillary element 383 and / or the second capillary element 384 prepared from the artificial capillary fiber material is greater than the density of the first liquid-retaining element 316 of the natural plant cotton / non-woven fabric fiber; the second capillary element 383 and / or the second capillary element 384 with a relatively large density has a relatively greater ability and efficiency in adsorbing and transferring liquid matrices than the first liquid-retaining element 316 prepared from the natural plant cotton / non-woven fabric fiber.

[0247] During use, the second capillary element 383 and / or the second capillary element 384 are used to absorb and buffer the liquid matrix within the first liquid-retaining element 316. The second capillary element 383 and / or the second capillary element 384 have a greater liquid absorption capacity than the first liquid-retaining element 316 and have a better liquid-locking ability to prevent the first liquid-retaining element 316 of the natural cotton fiber from being oversaturated with the absorbed liquid matrix and from seeping out.

[0248] according to Figures 16 to 27 As shown, after assembly, the second capillary element 383 and / or the second capillary element 384 are flush with the upper surface of the first liquid retaining element 316. The second capillary element 383 and / or the second capillary element 384 are spaced a distance d11 from the lower surface of the first liquid retaining element 316. In some embodiments, the distance d11 is approximately 1 to 4 mm.

[0249] according to Figures 16 to 27As shown, after assembly, the second capillary element 383 is longitudinally aligned with the first capillary element 326; but there is a spacing d11 between the second capillary element 383 and the first capillary element 326 and they are non-contacting. The second capillary element 384 is longitudinally aligned with the first capillary element 327; but there is a spacing d11 between the second capillary element 384 and the first capillary element 327 and they are non-contacting. Further in use, the spacing d11 is advantageous for preventing the liquid matrix delivered by the first capillary element 326 to the first liquid holding element 316 from being taken away by the second capillary element 383.

[0250] According to Figures 16 to 27 As shown, the inner surface of the first liquid output connector 323 is further arranged with a first capillary groove 3231; the inner surface of the second liquid output connector 324 is further arranged with a second capillary groove 3241. The first capillary groove 3231 is arranged extending from the free end of the first liquid output connector 323 towards the container 321. The second capillary groove 3241 is arranged extending from the free end of the second liquid output connector 324 towards the container 321.

[0251] In embodiments, the first capillary groove 3231 and the second capillary groove 3241 are arranged extending substantially in the longitudinal direction. The first capillary groove 3231 can be used to form a channel for air exchange between the first capillary element 326 and the inner surface of the first liquid output connector 323. The second capillary groove 3241 can be used to form a channel for air exchange between the first capillary element 327 and the inner surface of the second liquid output connector 324.

[0252] When the liquid matrix in the second liquid storage chamber 329 of the container 321 is delivered by the first capillary element 326 to the first liquid storage chamber / first liquid holding element 316, the air in the first liquid storage chamber / first liquid holding element 316 can further exchange with the second liquid storage chamber 329 through the first capillary groove 3231. And when the liquid matrix in the second liquid storage chamber 329 of the container 321 is delivered by the first capillary element 327 to the first liquid storage chamber / first liquid holding element 316, the air in the first liquid storage chamber / first liquid holding element 316 can further exchange with the second liquid storage chamber 329 through the first capillary element 327.

[0253] In some embodiments, the first capillary groove 3231 and / or the second capillary groove 3241 has a depth of about 0.5-2.0 mm and a width of about 0.5-2.0 mm.

[0254] In embodiments, the air exchange provided by the first capillary groove 3231 and / or the second capillary groove 3241 can be independent of the liquid matrix delivered by the first capillary element 326 / first capillary element 327, and it is advantageous for assisting air exchange to keep the air exchange channel unobstructed.

[0255] according to Figure 24 As shown, the extension length of the first capillary groove 3231 and / or the second capillary groove 3241 is shorter than the length of the first capillary element 326 / the first capillary element 327 .

[0256] according to Figures 16 to 27 As shown, the atomizer 31 is also provided with:

[0257] The ventilation channel R4 provides a channel path connecting the first liquid storage chamber of the atomizer 31 with the external atmosphere or outside air.

[0258] according to Figure 27 As shown in FIG, the ventilation channel R4 includes:

[0259] The first ventilation communication hole 313 is arranged on the main housing 311 and located at the first end 310;

[0260] A ventilation groove 373 is formed or arranged on the first sealing base 37; the ventilation groove 373 is formed on the first surface of the first sealing base 37 facing the first end 310;

[0261] The second ventilation communication hole 374 passes through or extends from the ventilation groove 373 to the second surface of the first sealing base 37 facing the first liquid storage chamber.

[0262] Alternatively, the ventilation channel R4 includes:

[0263] The first channel portion is defined by the first ventilation communication hole 313;

[0264] The second channel portion is defined by the ventilation groove 373;

[0265] The third channel portion is defined by the second ventilation communication hole 374.

[0266] The first channel portion is in communication with the external atmosphere; the third channel portion is in communication with the first liquid storage chamber; and the second channel portion provides communication between the first channel portion and the third channel portion.

[0267] In this embodiment, the first ventilation hole 313 is connected to the outside atmosphere. The first end 310 of the first ventilation hole 313 defines a first connection port for connecting to the outside atmosphere. Furthermore, the first ventilation hole 313 connects the ventilation channel R4 to the outside atmosphere. In this embodiment, the second ventilation hole 374 extends through the first liquid storage chamber and connects to the first liquid storage chamber. Furthermore, the second surface of the first sealing base 37 defines a second connection port connected to the first liquid storage chamber. Specifically, the second connection port defined by the second ventilation hole 374 connects to the first liquid storage chamber via a first space defined between the upper surface of the first liquid retaining element 316 and the first sealing base 37. Furthermore, the second ventilation hole 374 connects the ventilation channel R4 to the first liquid storage chamber. One of the first connection port defined by the first ventilation hole 313 and the second connection port defined by the second ventilation hole 374 is closer to the front side 150, while the other is closer to the rear side 160.

[0268] In an embodiment, the first ventilation communication hole 313 defines a first connection port at the first end 310 , which is spaced apart from the air outlet 312 , and an area of ​​the first connection port is smaller than an area of ​​the air outlet 312 .

[0269] In an embodiment, the ventilation groove 373 is arranged to extend along the thickness direction of the atomizing body 200 / atomizing body 300. Alternatively, after assembly, the ventilation groove 373 is arranged to extend along the thickness direction of the electronic atomizing device.

[0270] exist Figure 27 In the illustrated embodiment, the ventilation channel R4 connects the first liquid storage chamber of the atomizer 31 with the external atmosphere to balance the pressure of the first liquid storage chamber of the atomizer 31 and the outside world. Specifically, when the atomizing body 200 / atomizing body 300 is subjected to environmental testing or is transported at high altitude and low pressure, if the pressure in the first liquid storage chamber is greater than or less than the pressure of the outside world, the ventilation channel R4 connects the first liquid storage chamber of the atomizer 31 with the external atmosphere to balance their pressures. Or when the user consumes the liquid matrix in the first liquid storage chamber of the atomizer 31 during inhalation, the negative pressure in the first liquid storage chamber gradually increases, then the ventilation channel R4 can provide a channel path for external air to enter the first liquid storage chamber from the first ventilation connecting hole 313 to relieve the negative pressure in the first liquid storage chamber of the atomizer 31.

[0271] exist Figure 27In the illustrated embodiment, the first ventilation communication hole 313 is aligned with the ventilation groove 373 at one end along its length, thereby establishing air communication therewith; the second ventilation communication hole 374 is in air communication with the ventilation groove 373 at the other end along its length. The passage path of the ventilation channel R4 is thus curved. The passage path of the ventilation channel R4 is non-linear. Furthermore, the first passage portion defined by the first ventilation communication hole 313 and the third passage portion defined by the second ventilation communication hole 374 both extend longitudinally of the atomizer 31. Furthermore, the first passage portion defined by the first ventilation communication hole 313 and the third passage portion defined by the second ventilation communication hole 374 are offset relative to each other in the longitudinal direction of the atomizer 31.

[0272] exist Figure 27 In the illustrated embodiment, the ventilation passage R4 is located between the first liquid storage chamber of the atomizer 31 and the first end 310. The ventilation passage R4 does not bypass or cross the first liquid storage chamber of the atomizer 31.

[0273] In the embodiment, when the atomizing body 200 / atomizing body 300 is received in the power supply body, the first ventilation communication hole 313 is connected to the external atmosphere through the gap between the atomizing body 200 / atomizing body 300 and the first shell 11. Furthermore, when the atomizing body 200 / atomizing body 300 is received in the power supply body, the ventilation channel R4 can maintain communication between the first liquid storage chamber of the atomizing body 200 / atomizing body 300 and the atmosphere.

[0274] In the embodiment, for example Figure 28 As shown in , when the power supply body and / or the electronic atomization device are placed horizontally, one of the first ventilation communication hole 313 and the second ventilation communication hole 374 is close to the front side 150, and the other is close to the rear side 160, and the ventilation groove 373 of the ventilation channel R4 extends along the thickness direction of the atomization body 200 / atomization body 300. Then, the liquid matrix in the atomizer 31 cannot flow into the ventilation channel R4 to form a blockage. When the power supply body and / or the electronic atomization device are placed horizontally, it is beneficial to keep the ventilation channel R4 normal and prevent the liquid matrix from entering.

[0275] In some embodiments, the ventilation channel R4 is isolated or separated from the air flow channel through the atomizer 31.

[0276] according to Figure 3 As shown in , when the atomizing body 200 and the atomizing body 300 are received in the power supply body, the first ventilation communication hole 313 of the atomizing body 200 and the first ventilation communication hole 313 / first connection port of the atomizing body 300 are away from each other. Figure 3As shown in , the first ventilation communication hole 313 of the atomizing body 200 is basically close to the first side 130 , and the first ventilation communication hole 313 / first connection port of the atomizing body 300 is basically close to the second side 140 .

[0277] In an embodiment, when the atomizing body 200 is received in the power supply body, the first ventilation communication hole 313 of the atomizing body 200 is located between the air flow channel of the atomizing body 200 and the first side 130. When the atomizing body 300 is received in the power supply body, the first ventilation communication hole 313 of the atomizing body 300 is located between the air flow channel of the atomizing body 300 and the second side 140.

[0278] according to Figure 3 In the illustrated embodiment, when the atomizing body 200 is received in the power supply body, the first ventilation communication hole 313 of the atomizing body 200 is located between the longitudinal center axis of the power supply body and the rear side 160. Figure 3 In the illustrated embodiment, when the atomizing body 300 is received in the power supply body, the first ventilation communication hole 313 of the atomizing body 300 is located between the longitudinal center axis of the power supply body and the front side 150 .

[0279] Or according to Figure 3 In the illustrated embodiment, the distance between the first ventilation communication hole 313 of the atomizing body 200 and the front side 150 is greater than the distance between the first ventilation communication hole 313 and the rear side 160; the distance between the first ventilation communication hole 313 of the atomizing body 300 and the front side 150 is less than the distance between the first ventilation communication hole 313 and the rear side 160. The distance between the first ventilation communication hole 313 of the atomizing body 200 and the front side 150 is greater than the distance between the first ventilation communication hole 313 of the atomizing body 300 and the front side 150.
