Description

Technical Field

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

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

[0003] An example of such a product is a heating device that releases compounds by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol-providing products, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or a fragrance and / or an aerosol-generating substance (e.g., glycerol). Known electronic atomization devices replenish a liquid matrix to a reusable body by an independently replaceable liquid source. Utility Model Content

Figures 5 to 13 As shown, the first portion 316 has a window 314 facing the second side 140 ; ​​the first joint 1161 and the second joint 1162 extend from the window 314 into the holding space 150 .

[0172] In some embodiments, the first joint 1161 and the second joint 1162 are arranged to be spaced apart in the longitudinal direction; and the second joint 1162 is closer to the second portion 317 / distal end 120 than the first joint 1161 .

[0173] In some embodiments, the first joint 1161 and the second joint 1162 are hollow tubular; and the first joint 1161 and the second joint 1162 are in communication with the first liquid storage chamber. Specifically, the tubular first joint 1161 and the second joint 1162 are integrally molded with the first tubular element 116; further, the first joint 1161 and the second joint 1162 extend from the first tubular element 116.

[0174] according to Figures 5 to 13 As shown, the second connector 116 is configured to provide a channel for replenishing the liquid matrix of the reservoir 40 to the first liquid storage chamber. Fig.11 As shown by the middle arrow R31 , the liquid matrix in the liquid reservoir 40 flows to the capillary element 34 via the second connector 116 and is then received by the capillary element 34 , and then transferred to the liquid retaining element 33 by the capillary element 34 , thereby allowing the liquid reservoir 40 to replenish the liquid matrix to the first liquid storage chamber / liquid retaining element 33 through the second connector 116 .

[0175] according to Figures 5 to 13 As shown, the first joint 1161 is configured to provide an air exchange channel for connecting the first liquid storage chamber to the liquid reservoir 40. When the liquid reservoir 40 replenishes the liquid matrix to the first liquid storage chamber / liquid retaining element 33 through the second joint 116, the air in the first liquid storage chamber / liquid retaining element 33 flows into the liquid reservoir 40 via the first joint 1161 to balance or adjust the pressure in the liquid reservoir 40.

[0176] according to Figures 5 to 13 As shown, a connection structure is also arranged on the atomizing body 30 and the liquid reservoir 40, so as to prevent the liquid reservoir 40 from being separated from the atomizing body 30 along the width direction when the liquid reservoir 40 is combined with the atomizing body 30. Specifically, the connection structure includes:

[0177] The first connection structure 312 is, for example, formed or arranged as a protrusion on the surface of the first portion 316; the first connection structure 312 is arranged in the groove 311 on the surface of the first portion 316;

[0178] The second connecting structure 411 is located on the liquid reservoir 40 and is adapted to the first connecting structure 312; for example, the second connecting structure 411 has a connecting arm with a clamping hole 412; when the liquid reservoir 40 is combined with the atomizing body 30, the clamping protrusion of the first connecting structure 312 extends into the clamping hole 412 of the second connecting structure 411, so that the liquid reservoir 40 is stably combined with the atomizing body 30 to prevent the liquid reservoir 40 from being separated from the atomizing body 30 along the width direction.

[0179] according to Figures 5 to 13 As shown, the connection structure allows the first module 410 of the liquid reservoir 40 to move longitudinally relative to the atomizing body 30. Figures 5 to 13 In the embodiment, when the liquid reservoir 40 is combined with the atomizing body 30, the second connecting structure 411 is extended into the groove 311. The longitudinal dimension of the groove 311 is larger than the longitudinal dimension of the second connecting structure 411; the longitudinal dimension of the clamping hole 412 of the second connecting structure 411 is larger than the longitudinal dimension of the clamping protrusion of the first connecting structure 312. Thus, when the first connecting structure 312 and the second connecting structure 411 are connected, the first module 410 of the liquid reservoir 40 and the atomizing body 30 can move relative to each other in the longitudinal direction.

[0180] according to Figures 5 to 13 As shown, a positioning structure is also arranged between the atomizing body 30 and the liquid reservoir 40 to provide positioning when the liquid reservoir 40 is combined with the atomizing body 30. Specifically, the positioning structure includes:

[0181] a first positioning structure 313 , such as a positioning hole 313 formed or arranged on a surface of the first portion 316 ;

[0182] The second positioning structure 413 , for example, a positioning protrusion 413 formed or arranged on the surface of the liquid reservoir 40 .

[0183] When the liquid reservoir 40 is combined with the atomizing body 30, the second positioning structure 413 can be aligned with the first positioning structure 313, thereby providing guidance. Accordingly, the longitudinal dimension of the positioning hole 313 is larger than the longitudinal dimension of the positioning protrusion 413, so that the positioning protrusion 413 can move longitudinally in the positioning hole 313, which allows the first module 410 of the liquid reservoir 40 to move longitudinally relative to the atomizing body 30.

[0184] according to Figures 5 to 13 As shown, the liquid reservoir 40 includes a first module 410 and a second module 420, which is beneficial for the assembly and preparation of the liquid reservoir 40.

[0186] The second shell 41 at least partially defines the outer body of the liquid reservoir 40; when the liquid reservoir 40 is combined with the atomizing body 30, the second shell 41 of the liquid reservoir 40 and the first shell 31 of the atomizing body 30 jointly define the complete outer shell of the atomizer 100. And, when the atomizer 100 is received in the receiving cavity 211 of the power mechanism 200, part of the outer shell of the atomizer 100 is located outside the power mechanism 200.

[0187] according to Figures 5 to 13 As shown, the second housing 41 has an operating portion 418 on the second side 140; the operating portion 418 is defined by a step, a protrusion or a recess, etc. on the second side 140 of the second housing 41. In use, the operating portion 418 is configured to be operated by a user's finger, thereby driving the first module 410 of the liquid reservoir 40 to move relative to the atomizing body 30 in the longitudinal direction.

[0188] When the atomizer 100 is received in the receiving cavity 211 of the power mechanism 200, the operating portion 418 of the second housing 41 is exposed outside the receiving cavity 211. Specifically, for example, the operating portion 418 can abut against the first end of the power mechanism 200.

[0189] according to Figures 5 to 13 As shown, the first module 410 of the liquid reservoir 40 further includes:

[0190] The second liquid storage chamber 42 is formed or defined in the second housing 41 for storing liquid matrix. The side of the second liquid storage chamber 42 close to the proximal end 110 is closed, and the side of the second liquid storage chamber 42 toward the distal end 120 is open. In use, the liquid matrix in the second liquid storage chamber 42 leaves from the side of the distal end 120.

The closing element 43 defines a liquid output connector 431 to provide a channel path for the liquid matrix in the second liquid storage chamber 42 to leave or be output. After assembly, the liquid matrix in the second liquid storage chamber 42 can only be output or leave from the liquid output connector 431 of the closing element 43. The closing element 43 is rigid, for example, made of a rigid polymer plastic. According to Figures 5 to 13 As shown, after assembly, the gap between the closing element 43 and the second housing 41 is sealed by a sealing ring such as an O-ring.

[0193] according to Figures 5 to 13 As shown, a receiving cavity 450 is defined in the second housing 41 for receiving the second module 420 of the reservoir 40. The receiving cavity 450 is defined between the closing element 140 and the distal end 120 of the second housing 41. The side of the receiving cavity 450 toward the distal end 120 is open, so that the second module 420 of the reservoir 40 can be received or combined into the second housing 41 from one side of the distal end 120, and then assembled with the first module 410, for example Figure 8 As shown by the middle arrow P2, the second housing 41 is also provided with a first guide structure 416, such as a notch, and the second module 420 is provided with a second guide structure 466; when the second module 420 is received or combined into the second housing 41, the first guide structure 416 and the second guide structure 466 cooperate to provide guidance when the second module 420 is assembled with the first module 410.

The liquid output connector 431 has a free end located in the accommodating cavity 450 or toward the distal end 120, and the free end is closed. The liquid output connector 431 has a side wall or side surface extending longitudinally to the free end, and has a liquid outlet 432 located on the side wall or side surface for the liquid matrix to flow out. In some embodiments, the diameter or width of the liquid outlet 432 can limit the liquid matrix from flowing out in large quantities, and the liquid matrix can only flow out at a predetermined rate. In a specific embodiment, the diameter or width of the liquid outlet 432 is between 0.5 and 1.5 mm; in a more specific embodiment, the diameter or width of the liquid outlet 432 is 0.8 mm. The liquid outlet 432 is arranged near the free end of the liquid output connector 431.

[0195] according to Figures 5 to 13 As shown, the first module 410 of the liquid reservoir 40 further includes:

[0196] The deformable sealing valve 44 is mounted or arranged on the closing element 43 and is retained by the closing element 43. The sealing valve 44 is basically annular in shape; the sealing valve 44 has a sealing portion 441 arranged perpendicular to the axial direction; a slit or cutout 442 is provided on the sealing portion 441 to make the sealing portion 441 deformable, thereby allowing the ventilation joint 462 of the second module 420 to pass through the sealing portion 441 to the second liquid storage chamber 42. Furthermore, when the ventilation joint 462 of the second module 420 passes through the sealing portion 441 to the second liquid storage chamber 42, the sealing valve 44 provides sealing between the ventilation joint 462 of the second module 420 and the closing element 43. Furthermore, when the ventilation joint 462 of the second module 420 is removed from the second liquid storage chamber 42, the sealing portion 441 can return to Fig. 9 The initial state shown in FIG. 4 is thus closed, thereby closing the air connection between the second liquid storage chamber 42 and the ventilation joint 462. Fig. 9 As shown, the slits or cutouts 442 on the sealing portion 441 are in the shape of a cross.

[0197] according to Figures 5 to 13 As shown, the second module 420 of the liquid reservoir 40 includes:

When the second module 420 is assembled or combined in the first module 410, the liquid output connector 431 penetrates the plug hole 451 of the third sealing element 45 to the liquid buffer chamber 461. And, when the second module 420 is assembled or combined in the first module 410, the flexible third sealing element 45 elastically abuts between the base 46 and the closing element 43, thereby providing a seal therebetween. On the one hand, the liquid cache chamber 461 caches a certain amount of liquid matrix, shortening the path length of the liquid matrix replenished from the second liquid storage chamber 42 to the first liquid storage chamber, which is more advantageous for replenishing the liquid matrix to the first liquid storage chamber more quickly when the liquid matrix in the first liquid storage chamber is scarce. On the other hand, the liquid cache chamber 461 caches a certain amount of liquid matrix to maintain a certain hydraulic pressure, which helps to balance the liquid matrix delivery rate between the second liquid storage chamber 42 and the first liquid storage chamber, so that the delivery of the liquid matrix is ​​not too fast or too slow.

[0200] exist Figures 5 to 13 As shown in , the outer diameter and / or inner diameter of the liquid output connector 431 is gradually reduced, which is beneficial for inserting the liquid output connector 431 into the plug hole 451; specifically, the outer diameter and / or inner diameter of the liquid output connector 431 is gradually reduced in the direction close to the free end.

Accordingly, the fourth sealing element 48 also defines a ventilation channel 483 connecting the ventilation connector 462 and the first connection port 481. When the liquid reservoir 40 is combined with the atomizing body 30, the ventilation channel 483 at least partially provides air communication between the first connector 1161 and the ventilation connector 462. For example Fig.10 As shown by the middle arrow R41, when the liquid reservoir 40 is combined with the atomizer body 30, the air in the first liquid storage chamber / capillary element 34 flows into the first connecting port 481 through the first joint 1161, and is then delivered to the ventilation joint 462 through the ventilation channel 483, and finally escapes into the second liquid storage chamber 42 in the form of bubbles to relieve or balance the pressure in the second liquid storage chamber 42.

Similarly, the second connection port 482 is exposed through the avoidance port 471, so that the second joint 1162 can pass through the avoidance port 471 to the second module 420 to align with the second connection port 482 and connect.

[0208] exist Figures 5 to 13 As shown in the figure, a window 415 is also arranged on the second shell 41 of the first module 410; when the second module 420 is accommodated or combined in the first module 410, the covering element 17 extends out of the window 415 and is exposed, so that the first connector 1161 and the second connector 1162 extend into the second module 420 for connection.

[0209] exist Figures 5 to 13 In the embodiment, when the second module 420 and the first module 410 are longitudinally assembled, there is no rigid mechanical connection between them; thus, after assembly, the second module 420 and the first module 410 can be moved or separated longitudinally relative to each other.

[0210] according to Figure 4 , Fig.12 and Fig.13 As shown in, when the liquid reservoir 40 is combined with the atomizing body 30, the first joint 1161 and the second joint 1162 extend into the second module 420 for connection, so that the second module 420 is immovable in the longitudinal direction with respect to the atomizing body 30. The first module 410 can be moved between the first position and the second position relative to the atomizing body 30 by the user's operation in the longitudinal direction; when the first module 410 is moving, the first connecting structure 312 and the second connecting structure 411 can cooperate to provide a limit at the first position and / or the second position. Similarly, when the first module 410 is moving, the first positioning structure 313 and the second positioning structure 413 can also cooperate to provide a limit at the first position and / or the second position.

Figure 4 The first module 410 is in the first position, Fig.12 and Fig.13 Specifically, the user moves the operation unit 418 along the proximal end 110, such as Fig.10 As shown by the arrow P3, the first module 410 is Figure 4 The first position moves to Fig.12 and Fig.13 The second position in .

[0212] In the first position, the sealing element 43 and the flexible third sealing element 45 are longitudinally abutted and fitted; and the liquid output connector 431 passes through the insertion hole 451 of the third sealing element 45, and the liquid output connector 431 at least partially extends into the liquid buffer chamber 461, thereby making the second liquid storage chamber 42 and the liquid buffer chamber 461 / the first liquid storage chamber liquid-connected; at this time, the liquid matrix in the second liquid storage chamber 42 can be replenished to the liquid buffer chamber 461 through the liquid outlet 432 of the liquid output connector 431, and finally replenished to the first liquid storage chamber. In the second position, the sealing element 43 and the flexible third sealing element 45 are longitudinally separated and have a spacing d1; and the liquid outlet 432 of the liquid output connector 431 is located in the insertion hole 451 of the third sealing element 45; and the liquid outlet 432 is located in the sealing area defined between the first sealing rib 4511 and the second sealing rib 4512 on the inner surface of the insertion hole 451, so that the liquid outlet 432 is closed or blocked. At this time, the liquid matrix in the second liquid storage chamber 42 cannot be replenished to the liquid cache chamber 461 / the first liquid storage chamber.

[0213] In the first position, the ventilation connector 462 of the second module 420 passes through the sealing portion 441 of the sealing valve 44 of the first module 410 and extends into the second liquid storage chamber 42, thereby allowing the second liquid storage chamber 42 and the first liquid storage chamber / capillary element 34 to be air-connected, allowing the air in the first liquid storage chamber / capillary element 34 to enter the second liquid storage chamber 42 to relieve or balance the pressure difference between the first liquid storage chamber and the second liquid storage chamber 42. In the second position, the ventilation connector 462 of the second module 420 partially extends into the sealing valve 44 and does not penetrate the sealing portion 441, and then the sealing portion 441 of the sealing valve 44 abuts against the free end of the ventilation connector 462 to close the air connection between the ventilation connector 462 and the second liquid storage chamber 42; at this time, the second liquid storage chamber 42 and the first liquid storage chamber / capillary element 34 are in non-air connection to prevent the air in the first liquid storage chamber / capillary element 34 from entering into the second liquid storage chamber 42 to relieve or balance their pressure difference.

[0214] according to Figure 4 , Fig.12 and Fig.13As shown in the figure, in the first position, the surface of the second shell 41 of the first module 410 at the proximal end 110 is flatly engaged with the surface of the first shell 31 of the atomizing body 30. In the second position, the surface of the second shell 41 of the first module 410 at the proximal end 110 is more protruding than in the first position, and is non-flatly engaged with the surface of the first shell 31 of the atomizing body 30.

Also, a connection structure or a retaining structure is arranged between the first module 410 and the second module 420, such as a slide groove or a buckle structure arranged between the first module 410 and the second module 420; the connection structure or the retaining structure is used to provide connection, retention or limitation for the first module 410 and the second module 420 of the liquid reservoir 40 when they are in the first position and the second position.

[0216] In some embodiments, for example, according to Figure 5 As shown in FIG. 4 , when the first module 410 and the second module 420 of the liquid reservoir 40 are in the first position or in the second position, the liquid reservoir 40 can be combined with the atomizing body 30 or detached from the atomizing body 30 along the width direction.

[0217] In some embodiments, for example, before being sold or used by a consumer, the first module 410 and the second module 420 of the liquid reservoir 40 are pre-assembled in the first position and then packaged or sold; during product sales, production or packaging, a sealing component or sealing structure such as a sealing plug or a sealing film is arranged at the avoidance opening 471 on the covering element 17 to close and seal the avoidance opening 471. When used by a consumer, the sealing component or sealing structure such as the sealing plug or the sealing film is removed or torn off, so that the liquid reservoir 40 is combined with the atomizing body 30 again.

[0218] For example, in some embodiments, the first module 410 and the second module 420 of the liquid storage device 40 are pre-assembled in the second position before being packaged or sold before being sold or used by consumers; at this time, the second liquid storage cavity 42 is closed, and the avoidance opening 471 on the covering element 17 may not be provided with the sealing components such as the sealing plug or the sealing film. Of course, sealing components such as the sealing plug or the sealing film may also be provided in the same manner for multiple sealing.

[0276] exist Fig. 20 As shown, the liquid reservoir 100a is in a first position relative to the atomizing body 200a; in the first position, the first latching protrusion 11a extends into the first latching groove 212a, and the second latching protrusion 12a extends into the second latching groove 213a, thereby stably maintaining the liquid reservoir 100a in the first position.

[0277] exist Fig. 22 As shown, the liquid reservoir 100a is in the second position relative to the atomizing body 200a; in the second position, the first latching protrusion 11a extends into the second latching groove 213a, and the second latching protrusion 12a is located in the receiving cavity 211a and is in a non-connected structure, thereby stably maintaining the liquid reservoir 100a in the second position.

[0278] according to Figure 20 to Figure 23 As shown, in the first position of the reservoir 100a, the end cap 20 abuts against the inner bottom wall / partition wall 214a of the receiving chamber 211a. In the second position of the reservoir 100a, there is a distance d11 between the end cap 20 and the inner bottom wall / partition wall 214a of the receiving chamber 211a.

[0279] according to Figure 20 to Figure 21 As shown, in the first position, the liquid input connector 241a of the atomizing body 200a passes through the liquid output interface 431a and at least partially extends into the second liquid storage chamber 42a. Fig. 20 and Fig.21 As shown in FIG. 1 , the liquid inlet 2411a on the liquid input connector 241a at least partially extends into the second liquid storage chamber 42a, thereby being in fluid communication with the second liquid storage chamber 42a. Also, at this time, the first sealing element 242a also passes through the liquid output interface 431a and extends into the second liquid storage chamber 42a. In this first position, the liquid matrix of the second liquid storage chamber 42a can flow from the liquid inlet 2411a into the liquid input connector 241a, and then be absorbed by the capillary element 250a and transferred to the first liquid storage chamber / liquid retaining element 271a, as shown in FIG. Fig. 20 and Fig.21 As shown by the arrow R2.

[0280] In the first position, the liquid reservoir 100a and the atomizing body 200a jointly define an airflow channel of the electronic atomizing device. The airflow channel provides a flow path from the air inlet 221a via the atomizing assembly / heating element 280a to the air outlet 111a, so as to output the aerosol generated by the atomizing assembly / heating element 280a to the air outlet 111a. In an embodiment, the airflow path of the complete airflow channel is as follows: Fig. 20 As shown by the middle arrow R1, the air entering from the air inlet 221a passes through the air inlet channel to the atomizer assembly / heating element 280a, and carries the aerosol generated by the heating element 280a, passes through the trachea insertion port 2451a of the sealing element 310 in turn, and then enters the aerosol output tube 112a, and is finally output to the air outlet 111a to be inhaled by the user.

[0281] according to Figure 22 to Figure 23 As shown, the user moves the second housing 10a, for example, by pulling the housing 10a. Fig. 22 As shown by the arrow P12, the liquid reservoir 100a is Fig. 20 and Fig.21 The first position moves to Fig. 22 and Fig.23 In the second position, the liquid input connector 241a of the atomizing body 200a only extends into the liquid output interface 431a, and does not extend into the second liquid storage chamber 42a. Fig. 22 and Fig.23 As shown in FIG, the first sealing element 242a and the second sealing element 243a on the liquid input connector 241a elastically abut against the inner surface of the liquid output interface 431a to form a seal, thereby closing the liquid inlet 2411a. At this time, the liquid matrix in the second liquid storage chamber 42a cannot be replenished to the atomizing body 200a through the liquid inlet 2411a.

[0282] according to Figures 14 to 23 As shown, the number of liquid input connectors 241a of the atomizing body 200a is at least two, for example, the liquid input connector 241a may include a first connector and a second connector arranged in parallel; accordingly, the number of liquid output interfaces 431a on the liquid reservoir 100a is also at least two, for example, the liquid output interface 431a may include a first interface and a second interface arranged in parallel. 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 end of the first connector and the free end of the second connector are flush. And, the distance between the liquid inlet 2411a on the first connector and the free end is equal to the distance between the liquid inlet 2411a on the second connector and the free end.

[0283] In use, when the liquid matrix in the second liquid storage chamber 42a of the liquid reservoir 100a flows into the first liquid storage chamber / atomization body 200a from at least one of the liquid inlets 2411a on the multiple liquid input connectors 241a, the liquid inlet 2411a of at least another liquid input connector 241a is used as an air inlet to provide air from the first liquid storage chamber / atomization body 200a to enter the second liquid storage chamber 42a of the liquid reservoir 100a to maintain pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0284] Alternatively, in an embodiment, two liquid inlets 2411a are arranged on the side wall of each liquid input connector 241a in opposite directions in a radial direction; when one of the liquid inlets 2411a provides liquid matrix to supplement the first liquid storage chamber, the air in the first liquid storage chamber is provided from the other liquid inlet 2411a to enter the liquid reservoir 100a to maintain the pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0285] In a more preferred embodiment, for example Figures 14 to 23 As shown, the inner surface of the liquid input connector 241a is provided with:

[0286] The ventilation groove 2412a is basically arranged to extend in the longitudinal direction. The ventilation groove 2412a is located between the first liquid storage chamber / liquid retaining element 271a and the liquid inlet 2411a, and is used to form a ventilation channel between the capillary element 250a and the inner surface of the liquid input connector 241a. When the liquid matrix in the liquid reservoir 100a is transferred to the first liquid storage chamber / liquid retaining element 271a through the capillary element 250a, the air in the first liquid storage chamber / liquid retaining element 271a flows from the ventilation groove 2412a to the liquid inlet 2411a, and then escapes from the liquid inlet 2411a to the second liquid storage chamber 112a to balance the pressure of the second liquid storage chamber 112a and the first liquid storage chamber.

[0287] In some embodiments, the ventilation groove 2412a extends to the liquid inlet 2411a and is connected to the liquid inlet 2411a. The ventilation groove 2412a has a depth of about 0.5-2.0 mm and a width of about 0.5-2.0 mm.

[0288] In the embodiment, the ventilation channel provided by the ventilation groove 2412a allows air exchange between the first liquid storage chamber and the second liquid storage chamber 42a to avoid the liquid matrix transferred by the capillary element 250, which is beneficial for maintaining unobstructed ventilation.

[0289] In some embodiments, a plurality of partition spaces are also defined within the first liquid storage chamber, such as the partition space between the base 340a and the lower surface of the liquid retaining element 271a, the partition space between the outer surface of the liquid retaining element 271a and the inner surface of the bracket 240a, or the partition space between the upper surface of the liquid retaining element 271a and the bracket 240a.

[0290] Specifically, for example, the bracket 240a is also provided with an annular convex edge 2413a extending from the liquid input connector 241a toward the first liquid storage chamber; the upper surface of the liquid retaining element 271a abuts against the annular convex edge 2413a, so that the ventilation channel can only communicate with the airflow of the first liquid storage chamber through the microporous pores in the portion of the liquid retaining element 271a close to the upper surface. This prevents or avoids the air in the liquid input connector 241a from directly communicating with the outside air through the gap or gap between the liquid retaining element 330 and the bracket 240a. When the liquid matrix in the first liquid storage chamber is consumed, the portion of the liquid retaining element 271a close to the upper surface is free of liquid matrix, and the porous pores in this portion provide a channel for transmitting negative pressure between the liquid input connector 241a and the first liquid storage chamber, so that the liquid input connector 241a can maintain balance with the negative pressure or pressure in the first liquid storage chamber.

[0291] In some embodiments, in the first position, as the liquid matrix absorbed and retained by the liquid retaining element 271a in the first liquid storage chamber is consumed, when the negative pressure in the first liquid storage chamber exceeds a predetermined threshold, the liquid reservoir 100a is driven by the negative pressure to replenish the liquid matrix to the first liquid storage chamber, such as Fig.21 As shown by the arrow R2. When a predetermined amount of liquid matrix is ​​added to the first liquid storage chamber so that the negative pressure of the first liquid storage chamber is lower than the predetermined threshold again, the pressure difference between the first liquid storage chamber and the second liquid storage chamber 42a reaches a balance to prevent the liquid matrix from being further added to the first liquid storage chamber. Furthermore, during use, the liquid matrix can be added to the first liquid storage chamber only according to a predetermined amount each time as the user's suction or use control. Specifically, the electronic atomization device can respond to the user's suction, and automatically add the liquid matrix of the liquid storage chamber 100a to the atomization body 200a according to a predetermined amount during each suction process or during the lag period after the suction is completed.

[0292] In some embodiments, in the first position, there is a distance between the outer surface of the liquid input connector 241a and the inner surface of the liquid output interface 431a, and the distance defines a capillary channel located between the liquid input connector 241a and the liquid output interface 431a; and the liquid matrix flowing out of the liquid output interface 431a is adsorbed and retained through the capillary channel to prevent the liquid matrix of the second liquid storage chamber 42a from being replenished to the liquid input connector 241a in large quantities. In use, the capillary channel can control the liquid matrix of the second liquid storage chamber 42a to be replenished to the first liquid storage chamber according to a predetermined amount through capillary action, which is beneficial for preventing the first liquid storage chamber from being oversaturated with the liquid matrix. Specifically, in use, the liquid matrix in the capillary channel forms a liquid film to close the liquid inlet 2411a of the liquid input connector 241a, thereby preventing the liquid matrix from being replenished to the first liquid storage chamber in large quantities.

[0293] In an embodiment, the volume of the first liquid storage chamber is smaller than the volume of the second liquid storage chamber 42 / 42a. The amount of liquid matrix that the second liquid storage chamber 42 / 42a can absorb and store is greater than the amount of liquid matrix that the first liquid storage chamber can absorb and store. For example, in some specific embodiments, the second liquid storage chamber 42 / 42a can absorb and store 5 to 20 mL of liquid matrix, more specifically, for example, 10 mL; the first liquid storage chamber can store 5 to 20 mL of 0.5 to 3 mL of liquid matrix, more specifically, for example, 2 mL.

[0294] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
