According to Figures 5 to 13 As shown in FIG. 12, the complete airflow passage is jointly defined by a plurality of components. Specifically, according to Figures 5 to 13 As shown by the arrow R1 in FIG. 12, the external air entering from the second air inlet 322 passes through the second sealing element 325, the support element 35 in sequence, and is then delivered to the heating element 37; and then passes through the heating element 37 and carries the heated aerosol generated by the heating element 37, and is output to the air outlet 111 via the second tubular element 115, the first sealing element 114, the first absorbing element 113, and the aerosol output tube 112, and is then inhaled by the user at the air outlet 111.

[0101] According to Figures 5 to 13 As shown in FIG. 12, the atomization body 30 further comprises:

[0102] A porous second absorbing element 326, such as fiber cotton, is arranged adjacent to or around the second air inlet 321 for absorbing the aerosol condensate flowing to the second air inlet 321 in the airflow passage at the second air inlet 321. According to Figures 5 to 13 As shown in FIG. 12, the second absorbing element 326 is mounted or retained between the end cap 32 and the second portion 317; or, the second absorbing element 326 is between the end cap 32 and the first shell 31; or, the second absorbing element 326 is between the end cap 32 and the second sealing element 325.

[0103] According to Figures 5 to 13 As shown in FIG. 12, the atomization body 30 further comprises:

[0104] A first joint 1161 and a second joint 1162 at least partially extend from the atomization body 30 / the first portion 316 to the holding space 150.

[0105] According to Figures 5 to 13As shown, the first and second tabs 1161, 1162 extend from the first portion 316 toward the second side 140 in the width direction; and, the first and second tabs 1161, 1162 are at least partially exposed to the holding space 150. According to Figures 5 to 13 As shown, the first portion 316 has a window 314 toward the second side 140; and, the first and second tabs 1161, 1162 extend from the window 314 into the holding space 150.

[0106] In some embodiments, the first and second tabs 1161, 1162 are spaced apart in the longitudinal direction; and, the second tab 1162 is closer to the second portion 317 / distal end 120 than the first tab 1161.

[0107] In some embodiments, the first and second tabs 1161, 1162 are hollow tubes; and, the first and second tabs 1161, 1162 are in communication with the first reservoir. Specifically, the tubular first and second tabs 1161, 1162 are integrally molded with the first tubular element 116; and, the first and second tabs 1161, 1162 extend from the first tubular element 116. After assembly, the first and second tabs 1161, 1162 are opposite the porous wicking element 34; and, the first and second tabs 1161, 1162 are in fluid communication with the outer side surface of the wicking element 34.

[0108] According to Figures 5 to 13 As shown, the second tab 1162 is configured to provide a passage for replenishing the liquid substrate of the reservoir 40 to the first reservoir. In use, as shown by the arrow R31 in Figure 11 The liquid substrate in the reservoir 40 is received via the second tab 116 and transferred by the wicking element 34 to the liquid holding element 33, thereby causing the reservoir 40 to replenish the liquid substrate to the first reservoir / liquid holding element 33 through the second tab 116.

[0109] According to Figures 5 to 13 As shown, the first tab 1161 is configured to provide an air exchange passage for air communication between the first reservoir and the reservoir 40. When the reservoir 40 replenishes the liquid substrate to the first reservoir / liquid holding element 33 through the second tab 1162, the air in the first reservoir / liquid holding element 33 flows to the reservoir 40 via the first tab 1161 to balance or adjust the pressure in the reservoir 40.

[0110] According to Figures 5 to 13 As shown, the atomizing body 30 and the reservoir 40 are further provided with a connecting structure for preventing the reservoir 40 from being separated from the atomizing body 30 in the width direction when the reservoir 40 is combined with the atomizing body 30. Specifically, the connecting structure comprises:

[0111] The first connecting structure 312, for example, is a clamping protrusion formed or arranged on the surface of the first portion 316; the first connecting structure 312 is arranged in the groove 311 on the surface of the first portion 316;

[0112] 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 clamping hole 412 on the connecting arm; 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 in the width direction.

[0113] According to Figures 5 to 13 As shown in FIG. 1, the connecting structure allows the first module 410 of the liquid reservoir 40 to move relative to the atomizing body 30 in the longitudinal direction. For example, in Figures 5 to 13 When the liquid reservoir 40 is combined with the atomizing body 30, the second connecting structure 411 extends into the groove 311. At this time, the size of the groove 311 in the longitudinal direction is greater than the size of the second connecting structure 411 in the longitudinal direction; the size of the clamping hole 412 of the second connecting structure 411 in the longitudinal direction is greater than the size of the first connecting structure 312, for example, the clamping protrusion in the longitudinal direction. Therefore, 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.

[0114] According to Figures 5 to 13 As shown in FIG. 1, the connecting structure allows the first module 410 of the liquid reservoir 40 to move relative to the atomizing body 30 in the longitudinal direction. For example, in

[0115] The first positioning structure 313, for example, is a positioning hole 313 formed or arranged on the surface of the first portion 316;

[0116] The second positioning structure 413, for example, is a positioning protrusion 413 formed or arranged on the surface of the liquid reservoir 40.

[0117] 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 size of the positioning hole 313 in the longitudinal direction is greater than the size of the positioning protrusion 413 in the longitudinal direction, so that the positioning protrusion 413 can move in the longitudinal direction within the positioning hole 313, thereby allowing the first module 410 of the liquid reservoir 40 to move relative to the atomizing body 30 in the longitudinal direction.

[0118] According to Figures 5 to 13As shown, the liquid reservoir 40 comprises a first module 410 and a second module 420, which is advantageous for assembly and manufacture of the liquid reservoir 40. According to Figures 5 to 13 As shown, the second connecting structure 411 and the second positioning structure 413 are both formed or arranged on the first module 410.

[0119] According to Figures 5 to 13 As shown, the first module 410 of the liquid reservoir 40 comprises:

[0120] a second housing 41 at least partially defining an outer body of the liquid reservoir 40; when the liquid reservoir 40 is coupled to the atomizing body 30, the complete outer shell of the atomizer 100 is jointly defined by the second housing 41 of the liquid reservoir 40 and the first housing 31 of the atomizing body 30. When the atomizer 100 is received in the receiving cavity 211 of the power supply mechanism 200, part of the outer shell of the atomizer 100 is located outside the power supply mechanism 200.

[0121] According to Figures 5 to 13 As shown, the second housing 41 has an operation portion 418 at the second side 140; the operation portion 418 is defined by a step, a protrusion or a recess, etc. of the second housing 41 at the second side 140. In use, the operation portion 418 is configured to be operable by a finger of a user, thereby driving the first module 410 of the liquid reservoir 40 to move relative to the atomizing body 30 in the longitudinal direction.

[0122] When the atomizer 100 is received in the receiving cavity 211 of the power supply mechanism 200, the operation portion 418 of the second housing 41 is exposed outside the receiving cavity 211. Specifically, for example, the operation portion 418 can abut against the first end of the power supply mechanism 200.

[0123] According to Figures 5 to 13 As shown, the first module 410 of the liquid reservoir 40 further comprises:

[0124] a second liquid storage cavity 42 formed or defined in the second housing 41 for storing the liquid substrate. The second liquid storage cavity 42 is closed at a side close to the proximal end 110, and is open at a side facing the distal end 120. In use, the liquid substrate in the second liquid storage cavity 42 exits from the side facing the distal end 120.

[0125] According to Figures 5 to 13 As shown, the first module 410 of the liquid reservoir 40 further comprises:

[0126] The closure element 43 is arranged substantially perpendicular to the longitudinal direction of the second housing 41. The closure element 43 is arranged on the side of the second reservoir chamber 42 facing the distal end 120 and serves to close the side of the first reservoir chamber 112 facing the distal end 120. The closure element 43 is defined with a liquid output connector 431 for providing a passage path for the liquid matrix inside the second reservoir chamber 42 to exit or output. After assembly, the liquid matrix inside the second reservoir chamber 42 can only exit or output from the liquid output connector 431 of the closure element 43. The closure element 43 is rigid, for example made of rigid polymer plastic. According to Figures 5 to 13 As shown, the gap between the closure element 43 and the second housing 41 after assembly is sealed by a sealing ring, for example an O-ring.

[0127] According to Figure 8 As shown, the second housing 41 is defined with a receiving cavity 450 for receiving the second module 420 of the reservoir 40. The receiving cavity 450 is defined between the closure element 140 and the distal end 120 of the second housing 41. The side of the receiving cavity 450 facing the distal end 120 is open so that the second module 420 of the reservoir 40 can be received or coupled into the second housing 41 from the side of the distal end 120 to assemble with the first module 410, for example Figures 5 to 13 As shown, the second housing 41 is defined with a receiving cavity 450 for receiving the second module 420 of the reservoir 40. The receiving cavity 450 is defined between the closure element 140 and the distal end 120 of the second housing 41. The side of the receiving cavity 450 facing the distal end 120 is open so that the second module 420 of the reservoir 40 can be received or coupled into the second housing 41 from the side of the distal end 120 to assemble with the first module 410, for example

[0128] According to Figures 5 to 13 As shown, the closure element 43 is defined with at least one or more liquid output connectors 431 extending outwards towards the distal end 120. The at least one or more liquid output connectors 431 are located substantially inside the receiving cavity 450. The liquid output connector 431 is a hollow tube, and the inside of the liquid output connector 431 surrounds or defines a liquid output passage. The liquid output connector 431 has a free end located inside the receiving cavity 450 or towards 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 allow the liquid matrix to flow out only at a predetermined rate. In specific embodiments, the diameter or width of the liquid outlet 432 is between 0.5-1.5 mm; in more specific embodiments, the diameter or width of the liquid outlet 432 is 0.8 mm. The liquid outlet 432 is arranged close to the free end of the liquid output connector 431.

[0129] According toFigure 9 As shown, the first module 410 of the reservoir 40 further comprises:

[0130] The deformable sealing valve 44 is mounted or arranged on the closure element 43 and held by the closure element 43. The sealing valve 44 is substantially ring-shaped; the sealing valve 44 has a sealing portion 441 arranged perpendicularly to the axial direction; the sealing portion 441 is provided with slits or notches 442 or the like to make the sealing portion 441 deformable, so as to allow the ventilation connector 462 of the second module 420 to penetrate through the sealing portion 441 into the second reservoir cavity 42. And, when the ventilation connector 462 of the second module 420 penetrates through the sealing portion 441 into the second reservoir cavity 42, the sealing valve 44 provides sealing between the ventilation connector 462 of the second module 420 and the closure element 43. And, when the ventilation connector 462 of the second module 420 is removed from the second reservoir cavity 42, the sealing portion 441 can return to the initial state shown in Figure 9 Fig. 4, so as to close the air communication between the second reservoir cavity 42 and the ventilation connector 462. According to Figures 5 to 13 As shown, the slits or notches 442 on the sealing portion 441 are cross-shaped.

[0131] According to Figures 5 to 13 As shown, the second module 420 of the reservoir 40 comprises:

[0132] The rigid base 46 is hollow inside; when the second module 420 is assembled or combined into the first module 410, the base 46 is inside the second housing 41 of the first module 410 from the distal end 120, and closes the opening of the accommodation cavity 450 towards the distal end 120.

[0133] According to Figures 5 to 13As shown, a liquid buffer cavity 461 is arranged in the base 46 for buffering or storing the liquid substrate flowing out of the second liquid storage cavity 42 of the first module 410. The liquid buffer cavity 461 is open towards the side of the proximal end 110 and is shielded or closed by a flexible third sealing element 45 arranged on the base 46. The flexible third sealing element 45 is provided with a plug-in hole 451 for the liquid output connector 431 to penetrate into the liquid buffer cavity 461. When the second module 420 is assembled or coupled into the first module 410, the liquid output connector 431 penetrates the plug-in hole 451 of the third sealing element 45 into the liquid buffer cavity 461. Also, when the second module 420 is assembled or coupled into the first module 410, the flexible third sealing element 45 elastically abuts between the base 46 and the closure element 43, thereby providing a seal therebetween. In one aspect, the liquid buffer cavity 461 buffers a certain amount of liquid substrate, which shortens the path length of the liquid substrate from the second liquid storage cavity 42 to the first liquid storage cavity, which is more advantageous for faster replenishment of the liquid substrate to the first liquid storage cavity when the liquid substrate in the first liquid storage cavity is depleted. In another aspect, the liquid buffer cavity 461 buffers a certain amount of liquid substrate to maintain a certain amount of hydraulic pressure, which helps to balance the rate of delivery of the liquid substrate between the second liquid storage cavity 42 and the first liquid storage cavity, so that the delivery of the liquid substrate is not too fast or too slow.

[0134] In Figures 5 to 13 As shown in FIG. 4, the outer diameter and / or the inner diameter of the liquid output connector 431 is gradually reduced, which is advantageous for inserting the liquid output connector 431 into the plug-in hole 451; in particular, the outer diameter and / or the inner diameter of the liquid output connector 431 gradually reduces in the direction towards the free end.

[0135] In Figures 5 to 13 As shown in FIG. 4, the base 46 is further provided with a removable liquid filling plug 49 towards the side of the distal end 120; when the liquid filling plug 49 is removed, the liquid filling port is opened to enable filling of the liquid substrate into the liquid buffer cavity 461 from the liquid filling port by a liquid filling device, such as a liquid filling syringe. Figures 5 to 13 As shown in FIG. 4, the plug-in hole 451 and the liquid filling plug 49 / liquid filling port are arranged opposite to each other in the longitudinal direction of the second module 420 and are substantially longitudinally aligned.

[0136] In Figures 5 to 13 As shown in FIG. 4, the second module 420 of the liquid reservoir 40 comprises:

[0137] a first connecting port 481 and a second connecting port 482 arranged towards the first side 130; the first connecting port 481 and the second connecting port 482 are arranged spaced apart in the longitudinal direction. When the liquid reservoir 40 is coupled to the atomizing body 30, the first connector 1161 of the atomizing body 31 is inserted into the first connecting port 481 and the second connector 1162 is inserted into the second connecting port 482.

[0138] InFigures 5 to 13 As shown in FIG. 4, the first connection port 481 and the second connection port 482 are defined by a flexible fourth sealing element 48 received or arranged within the base 46 for providing sealing by the fourth sealing element 48 when the reservoir 40 is coupled to the atomizing body 30.

[0139] In Figure 10 As shown in FIG. 4, a liquid connection passage 4611 is also defined in the base 46 between the second connection port 482 and the liquid buffer cavity 461, such that the second connection port 482 and the liquid buffer cavity 461 are in liquid communication; and the liquid connection passage 4611 at least partially provides the liquid connection between the second connection 1162 and the liquid buffer cavity 461 when the reservoir 40 is coupled to the atomizing body 30. For example Figures 5 to 13 As shown by the arrow R32 in FIG. 4, the liquid substrate in the second reservoir cavity 42 is first output from the liquid outlet 432 of the liquid output connection 431 to the liquid buffer cavity 461, and then delivered to the second connection port 482 via the liquid connection passage 4611. In use, the second connection port 482 is used as an output or replenishment of the liquid substrate of the reservoir 40 / second reservoir cavity 42 to the liquid output interface of the first reservoir cavity / atomizing body.

[0140] In Figure 10 As shown in FIG. 4, the second module 420 is also arranged with a vent connection 462 extending out from the base 46 towards the proximal end 110; the vent connection 462 is protruded relative to other parts of the second module 420. The vent connection 462 is pierced through a flexible third sealing element 45. The vent connection 462 is hollow and tubular. Accordingly, the fourth sealing element 48 is also defined with a vent passage 483 communicating the vent connection 462 and the first connection port 481. The vent passage 483 at least partially provides the air communication between the first connection 1161 and the vent connection 462 when the reservoir 40 is coupled to the atomizing body 30. For example Figures 5 to 13 As shown by the arrow R41 in FIG. 4, when the reservoir 40 is coupled to the atomizing body 30, the air of the first reservoir cavity / capillary element 34 is first flowed into the first connection port 481 via the first connection 1161, then delivered to the vent connection 462 via the vent passage 483, and finally escaped into the second reservoir cavity 42 in the form of air bubbles to relieve or balance the pressure in the second reservoir cavity 42.

[0141] In Figures 5 to 13As shown in

[0142] In Figures 5 to 13 As shown in

[0143] In Figure 4 When the second module 420 is assembled with the first module 410 longitudinally, they are not fastened mechanically connected between each other; so after assembly, the second module 420 and the first module 410 can move or separate relative to each other in the longitudinal direction.

[0144] According to Figure 12 , Figure 13 and Figure 4 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 to connect, so that the second module 420 is longitudinally immovable with the atomizing body 30. The first module 410 can be moved by the user between the first position and the second position relative to the atomizing body 30 in the longitudinal direction; the first module 410 can be limited in position by the cooperation of the first connecting structure 312 and the second connecting structure 411 in the first position and / or the second position during movement. Similarly, the first module 410 can also be limited in position by the cooperation of the first positioning structure 313 and the second positioning structure 413 in the first position and / or the second position during movement.

[0145] According to Figure 12 , Figure 13 and Figure 4 When the liquid reservoir 40 is combined with the atomizing body 30, the first module 410 can be moved by the user through the operation part 418 between the first position and the second position relative to the atomizing body 30. Among them, Figure 12 the first module 410 is in the first position in Figure 13 , andFigure 10 The first module 410 is in the second position. Specifically, the user operates the operation portion 418 to move along the proximal end 110, as indicated by an arrow P3, so as to move the first module 410 from the first position to the second position in the first module 410 and the second module 420. Figure 4 The first module 410 is in the second position. Specifically, the user operates the operation portion 418 to move along the proximal end 110, as indicated by an arrow P3, so as to move the first module 410 from the first position to the second position in the first module 410 and the second module 420. Figure 12 The first module 410 is in the second position. Specifically, the user operates the operation portion 418 to move along the proximal end 110, as indicated by an arrow P3, so as to move the first module 410 from the first position to the second position in the first module 410 and the second module 420. Figure 13 The first module 410 is in the second position. Specifically, the user operates the operation portion 418 to move along the proximal end 110, as indicated by an arrow P3, so as to move the first module 410 from the first position to the second position in the first module 410 and the second module 420. Figure 4 The first module 410 is in the second position. Specifically, the user operates the operation portion 418 to move along the proximal end 110, as indicated by an arrow P3, so as to move the first module 410 from the first position to the second position in the first module 410 and the second module 420.

[0146] In the first position, the closure element 43 is longitudinally abutting and in contact with the flexible third sealing element 45; and the liquid output connector 431 passes through the insertion hole 451 of the third sealing element 45, and the liquid output connector 431 is at least partially inserted into the liquid buffer cavity 461, so that the second liquid storage cavity 42 is in liquid communication with the liquid buffer cavity 461 / the first liquid storage cavity; at this time, the liquid matrix in the second liquid storage cavity 42 can be supplemented to the liquid buffer cavity 461 through the liquid outlet 432 of the liquid output connector 431, and finally to the first liquid storage cavity. In the second position, the closure element 43 is longitudinally separated from the flexible third sealing element 45 with 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 convex rib 4511 and the second sealing convex rib 4512 on the inner surface of the insertion hole 451, so that the liquid outlet 432 is closed or closed. At this time, the liquid matrix in the second liquid storage cavity 42 cannot be supplemented to the liquid buffer cavity 461 / the first liquid storage cavity.

[0147] In the first position, the second module 420 air exchange connector 462 penetrates the sealing portion 441 of the sealing valve 44 of the first module 410 and is inserted into the second liquid storage cavity 42, so that the second liquid storage cavity 42 is in air communication with the first liquid storage cavity / capillary element 34, to allow the air in the first liquid storage cavity / capillary element 34 to enter the second liquid storage cavity 42 to relieve or balance the pressure difference between the first liquid storage cavity and the second liquid storage cavity 42. In the second position, the air exchange connector 462 of the second module 420 is partially inserted into the sealing valve 44 and does not penetrate the sealing portion 441, so that the free end of the air exchange connector 462 is closed by the sealing portion 441 of the sealing valve 44 to close the air communication between the air exchange connector 462 and the second liquid storage cavity 42; at this time, the second liquid storage cavity 42 is not in air communication with the first liquid storage cavity / capillary element 34, to prevent the air in the first liquid storage cavity / capillary element 34 from entering the second liquid storage cavity 42 to relieve or balance the pressure difference between them.

[0148] According to Figure 12 , Figure 13 and Figure 5As shown in FIG. 1, 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 atomization 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 convex than in the first position, and is non-flatly engaged with the surface of the first shell 31 of the atomization body 30.

[0149] In some embodiments, the first module 410 and the second module 420 of the liquid reservoir 40 can be movable relative to each other between the first position and the second position. In addition, a connecting structure or a retaining structure, such as a sliding groove or a snap structure arranged between the first module 410 and the second module 420, etc., is arranged between the first module 410 and the second module 420, and is used to provide connection or retention or positioning of the first module 410 and the second module 420 of the liquid reservoir 40 in the first position and the second position.

[0150] In some embodiments, for example, according to Figures 14 to 23 As shown in FIG. 1, the first module 410 and the second module 420 of the liquid reservoir 40 can be combined with or detached from the atomization body 30 in the first position or in the second position.

[0151] In some embodiments, for example, the first module 410 and the second module 420 of the liquid reservoir 40 are pre-assembled in the first position before packaging or selling; then a sealing member or a sealing structure, such as a sealing plug or a sealing film, is arranged at the relief opening 471 of the covering element 17 to seal the relief opening 471. When used by the consumer, the sealing member or the sealing structure is removed or torn off, and then the liquid reservoir 40 is combined with the atomization body 30.

[0152] For example, in some embodiments, the first module 410 and the second module 420 of the liquid reservoir 40 are pre-assembled in the second position before packaging or selling; at this time, the second liquid cavity 42 is closed, and the relief opening 471 of the covering element 17 can not be arranged with the above sealing member. Of course, the sealing member can also be arranged for multiple sealing.

[0153] Figures 1 to 4 FIG. 1 shows a schematic diagram of an electronic atomization device according to another embodiment; in this embodiment, the electronic atomization device comprises an atomization body 200a and a liquid reservoir 100a; the atomization body 200a and the liquid reservoir 100a can exist independently, and can be combined with each other.

[0154] In one embodiment, the reservoir 100a can store more liquid substrate than the atomizing body 200a for replenishing the atomizing body 200a with liquid substrate in use. The atomizing body 200a can store relatively less liquid substrate and atomize the liquid substrate to generate aerosol. The reservoir 100a and the atomizing body 200a exist independently of each other before they are combined; and the reservoir 100a and the atomizing body 200a together define a complete electronic atomization device after they are combined, for use or for aerosol vaping by a user.

[0155] In some embodiments, the reservoir 100a and the atomizing body 200a, when they exist independently of each other, are each incapable of being independently used or vaped by a user. For example, as shown in Figures 14 to 23 the reservoir 100a at least partially defines a mouthpiece for use or vaping by a user; and the atomizing body 200a can atomize liquid substrate to generate aerosol. When the reservoir 100a is removed or separated from the atomizing body 200a, the reservoir 100a is incapable of atomizing liquid substrate to generate aerosol by itself, and the atomizing body 200a is incapable of being vaped by a user by itself.

[0198] According to Figures 14 to 23 As shown, the liquid reservoir 100a further includes:

[0199] An air outlet 111a at the proximal end 110a for the user to draw on;

[0200] An aerosol output tube 112a extending from the air outlet 111a towards the distal end 120a for delivering aerosol to the air outlet 111a; in embodiments, the aerosol output tube 111 is integrally moulded with the second housing 10a;

[0201] A second liquid storage chamber 42a for storing liquid substrate; at least a portion of the second liquid storage chamber 42a is defined between the aerosol outlet tube 112a and the second housing 10a. The side of the second liquid storage chamber 42a proximal to the proximal end 110a is closed, and the boundary of the side of the second liquid storage chamber 42a distal to the distal end 120a is closed or defined by a closing element 43a. In use, the liquid substrate within the second liquid storage chamber 42a exits from the closing element 43a. In some embodiments, the second liquid storage chamber 42a is mainly defined between the second housing 10a and the aerosol outlet tube 112a.

[0202] According to Figures 14 to 23 As shown, the liquid reservoir 100a further comprises:

[0203] A closing element 43a arranged substantially perpendicular to the longitudinal direction of the liquid reservoir 100a for closing the opening of the second liquid storage chamber 42a distal to the distal end 120a. After assembly, the closing element 43a is covered by the end cap 20a. The closing element 43a is provided with at least one or more liquid outlet interfaces 431a that penetrate through the end cap 20a and extend to the distal end 120a. In this embodiment, and as terminated by the at least one or more liquid outlet interfaces 431a at the distal end 120a, the distal end 120a is defined.

[0204] In embodiments, the liquid outlet interface 431a is hollow and tubular in shape. The liquid outlet interface 431a internally surrounds or defines a liquid outlet channel 432a; the liquid outlet channel 432a is for providing a path for the liquid substrate within the second liquid storage chamber 42a to exit or be outputted.

[0205] According to Figures 20 to 23 As shown, after assembly, the aerosol outlet tube 112a at least partially penetrates through the closing element 43a and the end cap 20a, and in turn at least partially exposed outside the end cap 20a, and in turn facilitates connection with the air tube insertion interface 2451a on the atomizing body 200a.

[0206] According to Figure 20 As shown, the liquid reservoir 100a further comprises:

[0207] A flexible fourth sealing element 44a arranged at least partially between the closing element 43a and the second housing 10a for providing sealing therebetween. Further, at least a portion of the fourth sealing element 44a is also positioned between the closing element 43a and the aerosol outlet tube 112a for providing sealing therebetween.

[0208] According to Figure 22 As shown, when the liquid reservoir 100a is combined or received within the receiving cavity 211a, the liquid reservoir 100a is movable along the longitudinal direction relative to the atomizing body 100a between a first position and a second position.

[0209] Wherein, the surface of the second housing 10a is arranged with first and second longitudinally spaced protrusions 11a, 12a; the inner surface of the receiving cavity 211a is arranged with first and second longitudinally spaced slots 212a, 213a.

[0210] In Figures 20 to 23 the illustrated embodiment, the liquid reservoir 100a is in the first position relative to the atomizing body 200a; in the first position, the first protrusion 11a extends into the first slot 212a, and the second protrusion 12a extends into the second slot 213a, thereby stably retaining the liquid reservoir 100a in the first position.

[0211] In Figures 20 to 21 the illustrated embodiment, the liquid reservoir 100a is in the second position relative to the atomizing body 200a; in the second position, the first protrusion 11a extends into the second slot 213a, and the second protrusion 12a is located in the receiving cavity 211a and in a non-connected structure, thereby stably retaining the liquid reservoir 100a in the second position.

[0212] According to Figure 20 the illustrated embodiment, in the first position, the end cover 20 is in abutment with the inner bottom wall / separator wall 214a of the receiving cavity 211a. In the second position, the end cover 20 has a spacing d11 from the inner bottom wall / separator wall 214a of the receiving cavity 211a.

[0213] According to Figure 21 the illustrated embodiment, in the first position, the liquid input connector 241a of the atomizing body 200a penetrates the liquid output interface 431a and extends at least partially into the second liquid storage cavity 42a. In Figure 20 and Figure 21 the illustrated embodiment, the liquid inlet 2411a on the liquid input connector 241a extends at least partially into the second liquid storage cavity 42a, thereby being in fluid communication with the second liquid storage cavity 42a. At this time, the first sealing element 242a also penetrates the liquid output interface 431a and extends into the second liquid storage cavity 42a. In this first position, the liquid matrix of the second liquid storage cavity 42a can flow from the liquid inlet 2411a into the liquid input connector 241a, and then be transmitted to the first liquid storage cavity / liquid holding element 271a after being absorbed by the capillary element 250a, as indicated by arrow R2 in Figure 20 and Figures 22 to 23 .

[0214] In the first position, the liquid reservoir 100a and the atomization body 200a jointly define an airflow passage of the electronic atomization device. The airflow passage provides a flow path from the air inlet 221a to the air outlet 111a via the atomization assembly / heating element 280a, to output the aerosol generated by the atomization assembly / heating element 280a to the air outlet 111a. In embodiments, the airflow path of the complete airflow passage is as shown by the arrow R1 in FIG. 1A. Air entering from the air inlet 221a passes through the air inlet passage to the atomization assembly / heating element 280a, and carries the aerosol generated by the heating element 280a to sequentially pass through the air tube insertion port 2451a of the sealing element 310 and then enter the aerosol output tube 112a, and then finally be output to the air outlet 111a for suction by the user. Figure 22

[0215] According to the embodiment shown in FIG. 1B, the user moves the second housing 10a, specifically, for example, by a pulling operation, as shown by the arrow P12, so that the liquid reservoir 100a is moved from the first position in Figure 20 Figure 21 Figure 22 Figure 23 Figure 22 Figure 23 In the second position, the liquid input connector 241a of the atomization body 200a only extends into the liquid output interface 431a and does not extend into the second liquid storage cavity 42a. As shown in FIG. 1C and FIG. 1D, 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 substrate in the second liquid storage cavity 42a cannot be supplemented to the atomization body 200a through the liquid inlet 2411a. Figures 14 to 23 Figures 14 to 23

[0216] According to the embodiment shown in FIG. 1B, the number of liquid input connectors 241a of the atomization body 200a is at least two, for example, the liquid input connector 241a can include a first connector and a second connector arranged side by side; correspondingly, the number of liquid output interfaces 431a on the liquid reservoir 100a is also at least two, for example, the liquid output interface 431a can include a first interface and a second interface arranged side by side. The first connector and the second connector are arranged on the two sides of the atomization assembly, and the first interface and the second interface are arranged on the two sides of the atomization 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. Figure 21

[0217] ​​​​​​​​​In use, when liquid substrate in the second liquid storage chamber 42a of the liquid reservoir 100a flows from at least one of the liquid inlets 2411a of the plurality of liquid input joints 241a into the first liquid storage chamber / atomizing body 200a, at least another liquid inlet 2411a of the liquid input joint 241a is used as an air inlet to provide air from the second liquid storage chamber 42a of the liquid reservoir 100a into the first liquid storage chamber / atomizing body 200a to maintain pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0218] Alternatively, in an embodiment, two liquid inlets 2411a are arranged on the sidewall of each liquid input joint 241a in opposite radial directions; when one of the liquid inlets 2411a provides liquid substrate to supplement the first liquid storage chamber, air in the first liquid storage chamber flows from the other liquid inlet 2411a into the liquid reservoir 100a to maintain pressure balance between the first liquid storage chamber and the second liquid storage chamber 42a.

[0219] In a more preferred embodiment, for example ​ As shown, the inner surface of the liquid input joint 241a is arranged with:

[0220] The air exchange groove 2412a is arranged substantially in the longitudinal direction. The air exchange groove 2412a is located between the first liquid storage chamber / liquid retaining element 271a and the liquid inlet 2411a to form an air exchange passage between the capillary element 250a and the inner surface of the liquid input joint 241a. When the liquid substrate 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 air exchange groove 2412a to the liquid inlet 2411a, and then escapes from the liquid inlet 2411a into the second liquid storage chamber 112a to balance the pressure between the second liquid storage chamber 112a and the first liquid storage chamber.

[0221] In some embodiments, the air exchange groove 2412a extends to and connects with the liquid inlet 2411a. The air exchange groove 2412a has a depth of about 0.5-2.0 mm and a width of about 0.5-2.0 mm.

[0222] In an embodiment, the air exchange passage provided by the air exchange groove 2412a allows air exchange between the first liquid storage chamber and the second liquid storage chamber 42a to bypass the liquid substrate transferred by the capillary element 250a, which is advantageous for maintaining the air exchange passage unobstructed.

[0223] In some embodiments, the first liquid storage cavity is further defined by a plurality of spacers, such as the spacer between the base 340a and the lower surface of the liquid holding element 271a, the spacer between the outer surface of the liquid holding element 271a and the inner surface of the support 240a, or the spacer between the upper surface of the liquid holding element 271a and the support 240a.

[0224] Specifically, for example, the support 240a is also provided with an annular protrusion 2413a extending from the liquid inlet connector 241a toward the first liquid storage chamber; the upper surface of the liquid holding element 271a abuts against the annular protrusion 2413a, so that the ventilation channel can only communicate with the airflow of the first liquid storage chamber through the micropores in the portion of the liquid holding element 271a near the upper surface. This prevents or avoids the air in the liquid inlet connector 241a from directly communicating with the outside air through the gap or opening between the liquid holding element 330 and the support 240a. When the liquid matrix in the first liquid storage chamber is consumed, the portion of the liquid holding element 271a near the upper surface is without liquid matrix. The porous structure in this portion provides a channel for transmitting negative pressure between the liquid inlet connector 241a and the first liquid storage chamber, so that the liquid inlet connector 241a can maintain balance with the negative pressure or pressure in the first liquid storage chamber.

[0225] In some embodiments, in the first position, when the liquid matrix absorbed and held by the liquid holding element 271a in the first liquid reservoir is consumed, such that the negative pressure in the first liquid reservoir exceeds a predetermined threshold, the liquid reservoir 100a replenishes the liquid matrix into the first liquid reservoir under the drive of the negative pressure, such as... ​ As indicated by the middle arrow R2, when a predetermined amount of liquid matrix is ​​added to the first storage chamber, causing the negative pressure of the first storage chamber to fall below the predetermined threshold again, the pressure difference between the first and second storage chambers 42a reaches equilibrium, preventing further addition of liquid matrix to the first storage chamber. Therefore, during use, the liquid matrix can be added to the first storage chamber only in a predetermined amount each time, depending on the user's inhalation or usage control. Specifically, the electronic atomizing device can respond to the user's inhalation and automatically replenish the liquid matrix in the storage chamber 100a to the atomizing body 200a in a predetermined amount during each inhalation or during the lag period after inhalation.

[0226] In some embodiments, in the first position, there is a spacing between the outer surface of the liquid input joint 241a and the inner surface of the liquid output interface 431a, and the spacing defines a capillary passage between the liquid input joint 241a and the liquid output interface 431a; and the capillary passage adsorbs and holds the liquid matrix flowing out of the liquid output interface 431a to prevent the liquid matrix of the second liquid storage cavity 42a from supplementing the first liquid storage cavity in a large amount. In use, the capillary passage can control the liquid matrix of the second liquid storage cavity 42a to supplement the first liquid storage cavity in a predetermined amount by capillary action, which is advantageous for preventing the first liquid storage cavity from over-saturating the liquid matrix. Specifically, in use, the liquid matrix in the capillary passage forms a liquid film to seal the liquid inlet 2411a of the liquid input joint 241a, thereby preventing the liquid matrix from supplementing the first liquid storage cavity in a large amount.

[0227] In embodiments, the volume of the first liquid storage cavity is smaller than the volume of the second liquid storage cavity 42 / 42a. The second liquid storage cavity 42 / 42a can absorb and store a larger amount of liquid matrix than the first liquid storage cavity.
