Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and atomizer. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices replenish the liquid matrix to a reusable atomizer via a separately replaceable reservoir and pump the liquid matrix from the reservoir into the atomizer via a manually or electrically operated pump.

[0306] In some embodiments, the atomizer 200 and the power supply unit 100 exist independently of each other before being combined; and when the atomizer 200 is combined with the power supply unit 100, the power supply unit 100 can provide power to atomize the liquid matrix to generate an aerosol, which can then be used or inhaled by the user.

[0307] according to Figures 1 to 7 As shown, the electronic atomizing device also includes:

[0308] The reservoir 400 and the drive mechanism 300 are removably received by the power supply unit 100; the reservoir 400 stores a liquid matrix and can be driven by the user to replenish the liquid matrix in the reservoir 400 to the atomizer 200 by operating the drive mechanism 300.

[0309] according to Figures 1 to 7 As shown, the power supply unit 100 includes:

[0310] The first end 110 and the second end 120 are opposite to each other in the longitudinal direction;

[0311] The first side 130 and the second side 140 are opposite to each other along the width direction.

[0312] according to Figures 1 to 7 As shown, the power supply unit 100 includes:

[0313] The housing defines at least a portion of the outer surface of the power supply body 100. In embodiments, the housing is defined by a plurality of components, such as in Figures 1 to 7 In the case, the outer shell includes a first housing 10 and a second housing 141 located between the first housing 10 and the proximal end 110.

[0314] In one embodiment, the second housing 141 is arranged close to the second side 140 and defines the first end 110. The second housing 141 is spaced apart from the first side 130, and thus the second housing 141 of the outer shell protrudes relative to the first housing 10 at the first end 110.

[0315] In one embodiment, the first housing 10 has a window 142 on the second side 140; when the reservoir 400 is received by the power supply unit 100, the remaining amount of liquid matrix in the reservoir 400 can be observed through the window 142.

[0316] according to Figures 1 to 7 As shown, the power supply unit 100 includes:

[0317] The first receiving cavity 111 is arranged near the first side 130 and has an opening facing the first end 110. In use, the atomizer 200 can be received at least partially from the first end 110 into the first receiving cavity 111, thereby establishing a conductive connection with the power supply body 100.

[0318] In this embodiment, the first receiving cavity 111 is located between the second housing 141 and the first side 130. The surface of the second housing 141 facing the first side 130 is a longitudinally extending flat plane; thus, in use, when the atomizer 200 is received in the first receiving cavity 111, it can move against the surface of the second housing 141 facing the first side 130 toward the second end 120, so as to be guided by the surface of the second housing 141.

[0319] according to Figures 1 to 7 As shown, the power supply unit 100 also includes:

[0320] The second receiving cavity 112 is arranged near the second side 140 and has an opening toward the first end 110. In use, the drive mechanism 300 can be received at least partially from the first end 110 into the second receiving cavity 112.

[0321] In this embodiment, the second receiving cavity 112 is defined by a second housing 141. The second receiving cavity 112 is primarily located within the second housing 141.

[0324] Alternatively, in some other embodiments, the cover 121 is rotatably connected to the outer casing / first housing 10 by means of a hinge or pivot, thereby selectively closing or opening the third receiving cavity 122 by rotating the cover 121. Alternatively, in some other embodiments, the cover 121 is linearly movably arranged on the outer casing / first housing 10, and the third receiving cavity 122 is selectively closed or opened by moving the cover 121 between an open position and a closed position.

In an embodiment, the electronic support 115 at least partially surrounds the area between the circuit board 114 and the battery cell 113, thereby providing isolation between them.

[0333] In this embodiment, electronic components such as battery cell 113 and circuit board 114 are assembled within an electronic cavity defined between electronic support 115 and first housing 10. The electronic cavity is located between first receiving cavity 111 and second end 120, and between third receiving cavity 122 and first side 130.

[0334] During assembly, the circuit board 114 can be securely connected to the electronic support member 115 by mechanical means such as screws or clips, and is thus supported by the electronic support member 115. Furthermore, the battery cell 113 is housed within the electronic support member 115, and is thus supported and held by the electronic support member 115.

Specifically, the first air inlet 131 is provided with a blocking component that can be moved by the user, so that the area of ​​the first air inlet 131 blocked by the blocking component can be selectively adjusted by the user's movement operation, thereby adjusting the size of the first air inlet 131.

[0338] Alternatively, in some other variations, the size of the first air inlet 131 is given and non-adjustable.

[0339] according to Figures 1 to 7 As shown, the power supply unit 100 also includes:

[0340] An air intake passage 132 extends from a first air inlet 131 to a first receiving chamber 111; when the atomizer 200 is received in the first receiving chamber 111, the air intake passage 132 provides a communication path for delivering air from the first air inlet 131 to the atomizer 200. Alternatively, when the atomizer 200 is received in the first receiving chamber 111, the atomizer 200 is in communication with the first air inlet 131 via the air intake passage 132.

When the atomizer 200 is received within the first receiving cavity 111, the second electrical contact 222 of the atomizer 200 abuts against or contacts the first electrical contact 133 to form a conductive connection, thereby establishing a conductive connection between the atomizer 200 and the power supply unit 100.

[0351] In some embodiments, there are two first electrical contacts 133; the two first electrical contacts 133 are arranged at intervals on both sides of the port of the air intake channel 132 along the thickness direction of the power supply body 100.

When the drive mechanism 300 is received in the second receiving cavity 112 and combined with the power supply body 100, the cylinder element 35 is surrounded by the enclosure structures 142 and provided with retention, thereby stably holding the drive mechanism 300 in the second receiving cavity 112.

[0416] In some alternative embodiments, the operating element 31 can be pressed by a user, thereby driving the piston 33 within the cylinder element 35 to move from a first position toward a second end 120 to a second position. Furthermore, when the user releases the pressing operation on the operating element 31, the elastic restoring force of the elastic element 32 drives the piston 33 to move from the second position toward a first end 110 to the first position.

In another embodiment, the container 41 is arranged to extend substantially longitudinally. In some embodiments, the volume of the first reservoir 213 of the atomizer 200 is smaller than the volume of the second reservoir 411 of the container 41. For example, in some embodiments, the volume of the first reservoir 213 of the atomizer 200 may be between 2 and 5 mL; and the volume of the second reservoir 411 of the container 41 may be between 10 and 30 mL.

[0426] A liquid outlet pipe 44 extends longitudinally from the second liquid storage chamber 411 of the container 41 to the outside of the lid 42. Specifically, the lid 42 has a recess 421; the liquid outlet pipe 44 extends from the second liquid storage chamber 411 of the container 41 through the clearance hole 433 of the sealing element 43 into the recess 421 of the lid 42, and is partially exposed within the recess 421. After assembly, the liquid outlet pipe 44 has a free end extending into the second liquid storage chamber 411 of the container 41; the free end of the liquid outlet pipe 44 is close to the bottom surface of the second liquid storage chamber 411. Furthermore, the liquid outlet pipe 44 has a notch 441 for allowing the liquid matrix in the second liquid storage chamber 411 to enter the liquid outlet pipe 44.

In an embodiment, the first connector 512 of the fluid transfer mechanism 500 can squeeze or apply pressure to the blocking portion 45, thereby causing the slit 451 to open in response to an increase in pressure on the blocking portion 45, thereby allowing the first connector 512 to extend through the blocking portion 45 into the second reservoir 411 and communicate with the second reservoir 411.

[0429] In this embodiment, when the reservoir 400 is independently removed or replaced from the electronic atomizing device, the slit 451 of the shielding portion 45 contracts to form a self-sealing mechanism. This allows the shielding portion 45 to provide shielding or sealing between the first drive interface 424 and the second reservoir 411, preventing residual liquid matrix inside the second reservoir 411 from flowing out of the exposed first drive interface 424. Here, "self-sealing" is a mechanical term referring to the ability of an object to achieve a seal under certain conditions without the need for external auxiliary sealing devices.

When the atomizer 200 is received in the first receiving cavity 111, the fourth connector 532 is inserted into the second interface 232 of the atomizer 200, and then fluidly communicates with the first liquid storage cavity 213 through the second conduit 234.

[0452] according to Figures 3 to 5 , Figures 15 to 19 As shown, the fluid transfer mechanism 500 also includes:

[0453] A second fluid channel is disposed between the second drive interface 511 and the third connector 531; a portion of the second fluid channel may be located within the first support 51, and another portion may be located within the second support 52; for example, the second fluid channel includes a channel portion 513 located within the first support 51 and a channel portion 523 located within the second support 52. After assembly, the second fluid channel is defined by the channel portion 513 and the channel portion 523.

[0454] according to Figures 3 to 5 , Figures 15 to 19 As shown, the fluid transfer mechanism 500 also includes:

[0455] A second valve 524 is disposed within a second fluid passage for selectively opening or closing the second fluid passage. Specifically, the second valve 524 is disposed between a passage portion 513 within the first support 51 and a passage portion 523 within the second support 52.

[0456] In an embodiment, the second valve 524 can drive the piston 33 to move from a second position to a first position within the cylinder element 35 according to the elastic element 36 to open the second fluid channel, so that the air in the first liquid storage chamber 213 of the atomizer 200 is drawn into the cylinder 341 through the second fluid channel.

[0457] In this embodiment, the second valve 524 is a check valve or a one-way valve; specifically, the second valve 524 is a check valve that can open the second fluid channel when the pressure difference between the piston cylinder 341 and the first liquid storage chamber 213 of the atomizer 200 exceeds a predetermined threshold. Specifically, the second valve 524 is a silicone check valve; in this embodiment, the first side of the second valve 524 faces the second drive interface 511, and the second side faces the third connector 531; when the pressure on the first side of the second valve 524 is less than the pressure on the second side, and the pressure difference exceeds a predetermined threshold, the second valve 524 bends or deforms toward the second drive interface 511, thereby opening the second fluid channel.

[0458] according to Figures 3 to 5 , Figures 15 to 19 As shown, the fluid transfer mechanism 500 also includes:

[0459] A third fluid channel 525 is formed or connected between the second connector 522 and the fourth connector 532; after assembly, the third fluid channel 525 provides fluid communication between the liquid output pipe 44 of the reservoir 400 and the second pipe 234 of the atomizer 200.

[0460] Alternatively, in one embodiment, the assembled complete electronic atomizing device may include:

[0461] The first fluid channel is formed or connected between the piston cylinder 341 of the drive mechanism 300 and the second liquid storage chamber 411 of the liquid storage tank 400;

[0462] The second fluid channel is formed or connected between the piston cylinder 341 of the drive mechanism 300 and the first liquid storage chamber 213 of the atomizer 200;

[0463] The third fluid channel is formed or connected between the second liquid storage chamber 411 of the liquid storage tank 400 and the first liquid storage chamber 213 of the atomizer 200.

[0464] In this embodiment, the first fluid channel, the second fluid channel, and the third fluid channel are independent of each other. In this embodiment, the first fluid channel can be selectively opened or closed by the first valve 54. In this embodiment, the second fluid channel can be selectively opened or closed by the second valve 524. In this embodiment, the third fluid channel is always open.

[0465] In use, the electronic atomizer can be held by the user and selectively used in a first orientation (upright) and a second orientation (inverted). The first orientation, where the electronic atomizer is upright, can be characterized by the user holding the atomizer with the first end 110 facing away from the ground. In this first orientation, the electronic atomizer is upright, making it easy to inhale with the atomizer's outlet 211 facing the user's lips. The second orientation, where the electronic atomizer is inverted, can be characterized by the user holding the electronic atomizer with the first end 110 facing the ground. In this second orientation, the electronic atomizer is inverted, with the atomizer's outlet 211 facing the ground.

[0466] In the embodiments, according to Figures 20 to 22 As shown, in the first orientation where the electronic atomizing device is upright, due to gravity, the notch 441 of the liquid output pipe 44 of the reservoir 400 is sealed or submerged by the liquid matrix in the second reservoir 411; and in the first orientation where the electronic atomizing device is upright, the first free end 235 of the first pipe 233 of the atomizer 200 is not sealed or submerged by the liquid matrix in the first reservoir 213, and the second free end 236 of the second pipe 234 is sealed or submerged by the liquid matrix in the first reservoir 213.

[0467] See Figures 20 to 22 As shown, in the first orientation where the electronic atomizing device is in the upright position, the user can press or operate the operating element 31 of the drive mechanism 300 to replenish the liquid matrix in the second liquid storage chamber 411 of the liquid reservoir 400 into the first liquid storage chamber 213 of the atomizer 200. Specifically, during the user's operation of pressing the operating element 31, the flow process of air and liquid matrix in the electronic atomizing device may include:

[0468] S10, such as Figure 20As indicated by the middle arrow P11, when the user presses the operating element 31, it drives the piston 33 to move from the first position to the second position within the cylinder 341, at which point the elastic element 36 is compressed. During the movement of the piston 33, the space within the cylinder 341 is compressed or reduced, thereby driving the first valve 54 to open the first fluid passage 514. This allows air within the cylinder 341 to enter the second reservoir chamber 411 of the reservoir 400 via the first fluid passage 514 within the fluid transmission mechanism 500. Figure 20 As indicated by the middle arrow R41.

[0469] At this time, because air from the cylinder 341 enters the second liquid storage chamber 411 of the liquid reservoir 400, the pressure in the second liquid storage chamber 411 increases, resulting in a positive pressure state; such as Figure 21 As shown by the middle arrow R42, the liquid matrix in the second liquid storage chamber 411 can be driven by positive pressure, enter the liquid output pipe 44 through the notch 441, and then enter the first liquid storage chamber 213 of the atomizer 200 through the third fluid channel 525 and the second pipe 234 of the atomizer 200, thereby replenishing the liquid matrix of the second liquid storage chamber 411 to the first liquid storage chamber 213.

[0470] When the liquid matrix is ​​replenished into the first liquid storage chamber 213, causing the pressure inside the first liquid storage chamber 213 to be in a positive pressure state, such as Figure 20 and Figure 21 As shown by the middle arrow R43, the air in the first liquid storage chamber 213 can be discharged into the airflow channel of the atomizer 200 through the first perforation 261 on the first tubular element 26 and the capillary micropores in the first section of the capillary element 27, and then enter the outside atmosphere, thereby balancing or eliminating the positive pressure in the first liquid storage chamber 213.

[0471] S20, such as Figure 22 As indicated by the middle arrow P22, after the user releases the pressure on the operating element 31, the elastic restoring force of the elastic element 36 resets the operating element 31 and the piston 33, driving the piston 33 to move from the second position to the first position. During the movement of the piston 33, the space inside the cylinder 341 gradually expands, generating negative pressure, which in turn drives the second valve 524 to open the second fluid channel. This allows the air in the first liquid storage chamber 213 of the atomizer 200 to enter the cylinder 341 through the first pipe 233 and the second fluid channel in the fluid transmission mechanism 500, as shown in the image. Figure 22 As indicated by the middle arrow R44.

[0472] When the air in the first liquid storage chamber 213 is drawn into the plug cylinder 341, causing the first liquid storage chamber 213 to be in a negative pressure state, the external air can be replenished into the first liquid storage chamber 213 through the capillary micropores in the first section of the capillary element 27 and the first perforation 261 on the first tubular element 26, thereby balancing or eliminating the negative pressure in the first liquid storage chamber 213.

[0473] In an embodiment, the piston 33 has a given travel distance or stroke when the user presses it, thereby driving a predetermined amount of liquid matrix to be replenished from the second reservoir 411 of the reservoir 400 to the first reservoir 213 in each user operation. In some embodiments, the predetermined amount of liquid matrix may be approximately 0.2 to 2 mL.

[0474] In an embodiment, in the first orientation where the electronic atomizing device is upright, the second perforation 262 of the first tubular element 26 is close to the bottom surface of the first liquid storage chamber 213, and the second perforation 262 is sealed or submerged by the liquid matrix in the first liquid storage chamber 213; thus, in the first orientation where the electronic atomizing device is upright, the second perforation 262 of the first tubular element 26 provides delivery of the liquid matrix in the first liquid storage chamber 213 to the atomizing assembly 29. In the embodiment, in the first orientation where the electronic atomizing device is in the upright position, the first perforation 261 of the first tubular element 26 is close to the top surface of the first liquid storage chamber 213, and thus the first perforation 261 is not sealed or submerged by the liquid matrix in the first liquid storage chamber 213; thus, in the first orientation where the electronic atomizing device is in the upright position, the first perforation 261 of the first tubular element 26 provides communication between the first liquid storage chamber 213 and the outside air, so as to provide pressure relief when the liquid matrix is ​​added to the first liquid storage chamber 213, causing the pressure in the first liquid storage chamber 213 to increase, or to provide air replenishment when the air in the first liquid storage chamber 213 is drawn into the plug cylinder 341, causing the first liquid storage chamber 213 to be under negative pressure, thereby balancing the pressure of the first liquid storage chamber 213 and the outside.

[0475] In this embodiment, during the process of the user operating the drive mechanism 300 to replenish the liquid matrix from the second reservoir 411 to the first reservoir 213, the first valve 54 opening the first fluid channel 514 and the second valve 524 opening the second fluid channel are performed alternately; however, the opening of the first fluid channel 514 by the first valve 54 and the opening of the second fluid channel by the second valve 524 are not performed simultaneously. The first fluid channel 514 and the second fluid channel are not opened at the same time.

[0476] In the embodiments, according to Figures 23 to 25As shown, in the second orientation where the electronic atomizing device is inverted, due to gravity, the notch 441 of the liquid output pipe 44 of the reservoir 400 is not sealed or submerged by the liquid matrix in the second reservoir 411, and is instead surrounded by air in the second reservoir 411; and, in the second orientation where the electronic atomizing device is inverted, the first free end 235 of the first pipe 233 of the atomizer 200 is sealed or submerged by the liquid matrix in the first reservoir 213, and the second free end 236 of the second pipe 234 is not sealed or submerged by the liquid matrix in the first reservoir 213.

[0477] Figures 23 to 25 The diagram shows a second orientation in which, when a user holds the electronic atomizing device in an inverted position, the liquid matrix in the first reservoir 213 of the atomizer 200 can be drawn into the cylinder 341 of the drive mechanism 300 by pressing or operating the operating element 31 of the drive mechanism 300. According to... Figures 23 to 25 As shown, in the second orientation where the electronic atomizing device is in an inverted state, the flow process of air and liquid matrix within the electronic atomizing device when the user presses the operating element 31 may include:

[0478] S10a, such as Figure 23 As indicated by the middle arrow P21, when the user presses the operating element 31, it drives the piston 33 to move from the first position to the second position within the cylinder 341, at which point the elastic element 36 is compressed. During the movement of the piston 33, the space within the cylinder 341 is compressed or reduced, driving the first valve 54 to open the first fluid passage 514, thereby allowing air from the cylinder 341 to enter the second storage chamber 411 of the reservoir 400 via the first fluid passage 514 within the fluid transmission mechanism 500. Figure 23 As indicated by the middle arrow R51, the second liquid storage chamber 411 is under positive pressure.

[0479] In the second orientation where the electronic atomizing device is inverted, the notch 441 of the liquid output tube 44 is not submerged by the liquid matrix in the second liquid storage chamber 411; and further according to Figure 24 As shown by the middle arrow R51, when air enters the second liquid storage chamber 411 from the cylinder 341, it escapes in the form of bubbles, passes through the liquid matrix, and enters the liquid output pipe 44 through the notch 441. The positive pressure in the second liquid storage chamber 411 drives it to enter the first liquid storage chamber 213 of the atomizer 200 from the third fluid channel 525 and the second pipe 234.

[0480] When air enters the first liquid storage chamber 213, causing the pressure inside the first liquid storage chamber 213 to become positive, such as Figure 23 and Figure 24As shown by the middle arrow R51, the air in the first liquid storage chamber 213 can be discharged into the airflow channel of the atomizer 200 through the second perforation 262 on the first tubular element 26 and the capillary micropores in the second section of the capillary element 27, and then enter the outside atmosphere, thereby balancing or eliminating the positive pressure in the first liquid storage chamber 213.

[0481] S20a, such as Figure 25 As shown by the middle arrow P22, after the user releases the pressure on the operating element 31, the elastic restoring force of the elastic element 36 resets the operating element 31 and the piston 33, driving the piston 33 to move from the second position to the first position. During the movement of the piston 33, the space inside the cylinder 341 gradually expands, generating negative pressure, which in turn drives the second valve 524 to open the second fluid channel and draws the liquid matrix in the first storage chamber 213 from the first pipe 233 and the second fluid channel in the fluid transfer mechanism 500 into the cylinder 341 for buffering. Figure 25 As indicated by the middle arrow R52.

[0482] When the liquid matrix in the first liquid storage chamber 213 is drawn into the plug cylinder 341, causing a negative pressure state in the first liquid storage chamber 213, external air can be supplied to the first liquid storage chamber 213 through the capillary micropores in the second section of the capillary element 27 and the first perforation 261 on the first tubular element 26, thereby balancing or eliminating the negative pressure in the first liquid storage chamber 213. Figure 25 As indicated by the middle arrow R53.

[0483] During use, the liquid matrix stored in the plug cylinder 341 can be discharged into the second reservoir chamber 411 of the reservoir 400 when the user presses the operating element 31 to compress the volume of the plug cylinder 341 in the next operation.

[0484] In this embodiment, in the second orientation where the electronic atomizing device is inverted, the second perforation 262 of the first tubular element 26 is near the bottom surface of the first liquid storage chamber 213, and thus the second perforation 262 is not sealed or submerged by the liquid matrix in the first liquid storage chamber 213; and the first perforation 261 is near the top surface of the first liquid storage chamber 213, and thus the first perforation 261 is sealed or submerged by the liquid matrix in the first liquid storage chamber 213. Furthermore, in the second orientation where the electronic atomizing device is inverted, the second perforation 262 of the first tubular element 26 provides communication between the first liquid storage chamber 213 and the outside atmosphere, so as to provide pressure relief when air enters the first liquid storage chamber 213 causing an increase in pressure, or to provide air replenishment when the liquid matrix in the first liquid storage chamber 213 is drawn into the plug cylinder 341 causing a negative pressure in the first liquid storage chamber 213, thereby balancing the pressure of the first liquid storage chamber 213 with the outside.

[0485] Figures 26 to 30A schematic diagram of an electronic atomizing device according to another embodiment is shown; in this embodiment, the electronic atomizing device includes an atomizer 200a and a power supply unit 100a; the power supply unit 100a and the atomizer 20a can each exist independently, while also being combined with each other.

[0486] In some embodiments, the atomizer 200a and the power supply unit 100a exist independently of each other before being combined; and when the atomizer 200a is combined with the power supply unit 100a, the power supply unit 100a can provide power to atomize the liquid matrix to generate an aerosol, which can then be used or inhaled by the user.

[0487] according to Figures 26 to 32 As shown, the electronic atomizing device also includes:

[0488] The reservoir 400a and the drive mechanism 300a are removably received by the power supply unit 100a; the reservoir 400a stores a liquid matrix and can be driven by the user to replenish the liquid matrix in the reservoir 400a to the atomizer 200a by operating the drive mechanism 300a.

[0489] according to Figures 26 to 32 As shown, the power supply unit 100a includes:

[0490] The first end 110a and the second end 120a are opposite to each other in the longitudinal direction;

[0491] The first side 130a and the second side 140a are opposite to each other along the width direction.

[0492] according to Figures 26 to 32 As shown, the power supply unit 100a includes:

[0493] The housing defines at least a portion of the outer surface of the power supply body 100a. In embodiments, the housing is defined by a plurality of components, such as in Figures 26 to 32 In the case, the outer shell includes a first housing 10a and a second housing 141a located between the first housing 10a and the first end 110a.

[0494] In one embodiment, the second housing 141a is arranged close to the second side 140a and defines the first end 110a. The second housing 141a is spaced from the first side 130a, and thus the second housing 141a of the outer shell protrudes relative to the first housing 10a at the first end 110a.

[0495] In one embodiment, the first housing 10a has a window 142a on the second side 140a; when the reservoir 400a is received by the power supply unit 100a, the remaining amount of liquid matrix in the reservoir 400a can be observed through the window 142a.

[0496] according to Figures 26 to 32 As shown, the power supply unit 100a includes:

[0497] The first receiving cavity 111a is arranged near the first side 130a and has an opening facing the first end 110a; in use, the atomizer 200a can be received at least partially from the first end 110a into the first receiving cavity 111a, thereby establishing a conductive connection with the power supply body 100a.

[0498] In this embodiment, the first receiving cavity 111a is located between the second housing 141a and the first side 130a. The surface of the second housing 141a facing the first side 130a is a longitudinally extending flat plane; thus, in use, when the atomizer 200a is received in the first receiving cavity 111a, it can move against the surface of the second housing 141a facing the first side 130a toward the second end 120a, so as to be guided by the surface of the second housing 141a.

[0499] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0500] The second receiving cavity 112a is arranged near the second side 140a and has an opening facing the first end 110a. In use, the drive mechanism 300a can be received at least partially from the first end 110a into the second receiving cavity 112a.

[0501] In this embodiment, the second receiving cavity 112a is defined by a second housing 141a. The second receiving cavity 112a is primarily located within the second housing 141a.

[0502] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0503] The third receiving cavity 122a is arranged close to the second side 140a and has an opening facing the second end 120a; the first housing 10a is provided with a removable door cover 121a at the second end 120a for covering or closing the opening of the third receiving cavity 122a facing the second end 120a; when the door cover 121a is removed, the opening of the third receiving cavity 122a is opened, thereby allowing the reservoir 400a to be received into or removed from the user's second end 120a.

[0504] Alternatively, in some other embodiments, the cover 121a is rotatably connected to the outer casing / first housing 10a by means of a hinge or pivot; thereby, the third receiving cavity 122a is selectively closed or opened by rotation. Alternatively, in some other embodiments, the cover 121a is linearly movably arranged on the outer casing / first housing 10a, and the third receiving cavity 122a is selectively closed or opened by moving the cover 121a between an open position and a closed position.

[0505] In this embodiment, the third receiving cavity 122a and the second receiving cavity 112a are longitudinally isolated.

[0506] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0507] Battery cell 113a, used for power supply;

[0508] Circuit board 114a, such as PCB board, FPC board, etc., is used to control the battery cell 113a to provide power to atomizer 200a.

[0509] In this embodiment, the battery cell 113a and the circuit board 114a are arranged substantially along the longitudinal direction of the power supply body 100a. Furthermore, the battery cell 113a and the circuit board 114a are mounted and arranged between the first receiving cavity 111a and the second end 120a; and the battery cell 113a and the circuit board 114a are mounted and arranged between the first side 130a and the third receiving cavity 122a.

[0510] In one embodiment, the circuit board 114a is arranged closer to the first side 130a than the battery cell 113a.

[0511] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0512] An electronic support 115a is provided for supporting or holding electronic components such as circuit board 114a and battery cell 113a. In an embodiment, the electronic support 115a at least partially surrounds the area between circuit board 114a and battery cell 113a, thereby providing isolation between them.

[0513] In this embodiment, electronic components such as battery cell 113a and circuit board 114a are assembled within an electronic cavity defined between electronic support member 115a and first housing 10a. The electronic cavity is located between first receiving cavity 111a and second end 120a, and between third receiving cavity 122a and first side 130a.

[0514] During assembly, the circuit board 114a is securely connected to the electronic support member 115a via mechanical connections such as screws or clips, and is thus supported by the electronic support member 115a. Furthermore, the battery cell 113a is housed within the electronic support member 115a, and is thus supported and held by the electronic support member 115a.

[0515] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0516] The first air intake 131a is used to provide air intake.

[0517] In one embodiment, a first air inlet 131a is arranged on a first side 130a. In another embodiment, the size of the first air inlet 131a is adjustable. Specifically, a blocking component or similar component that can be moved by a user is arranged inside the first air inlet 131a, so that the area blocked by the blocking component can be selectively adjusted by the user's movement, thereby adjusting the size of the first air inlet 131a.

[0518] Alternatively, in some other variations, the size of the first air inlet 131a is given and not adjustable.

[0519] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0520] An air intake channel 132a extends from a first air intake port 131a to a first receiving chamber 111a. When the atomizer 200a is received in the first receiving chamber 111a, the air intake channel 132a provides a communication path for delivering air from the first air intake port 131a to the atomizer 200a. Alternatively, when the atomizer 200a is received in the first receiving chamber 111a, the atomizer 200a is connected to the first air intake port 131a via the air intake channel 132a. When the atomizer 200a is received in the first receiving chamber 111a, the second air intake port 221a of the atomizer 200a is aligned with and connected to the port of the air intake channel 132a located in the first receiving chamber 111a.

[0521] according to Figure 30 As shown, the air intake channel 132a is located at the port of the first receiving cavity 111a and is basically elliptical. Specifically, in the embodiment, the extension dimension of the air intake channel 132a at the port of the first receiving cavity 111a along the width direction of the power supply body 100a is greater than the extension dimension along the thickness direction of the power supply body 100a.

[0522] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0523] An airflow sensor 116a, such as a microphone sensor or a MEMS sensor, is used to sense changes in airflow through the power supply unit 100a during user inhalation. In an embodiment, the airflow sensor 116a is mounted on a circuit board 114a, for example, by means of soldering or other secure mounting methods. Figure 29 In the embodiment shown, the airflow sensor 116a is arranged on the surface of the circuit board 114a facing the second side 140a.

[0524] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0525] A flexible encapsulation element 117a, for example made of silicone or thermoplastic elastomer, encapsulates the airflow sensor 116a.

[0526] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0527] The sensing connection channel 118a is used to connect the airflow sensor 116a to the air intake channel 132a, so that the airflow sensor 116a can sense the changes in airflow flowing through the air intake channel 132a.

[0528] In this embodiment, the sensing connection channel 118a is essentially defined by the wrapping element 117a. The sensing connection channel 118a is arranged to extend longitudinally along the power supply body 100a.

[0529] according to Figures 26 to 32 As shown, the power supply unit 100a also includes:

[0530] The first electrical contact 133a is at least partially exposed within the first receiving cavity 111a. The first electrical contact 133a is substantially elastic, for example, it includes a conductive spring pin. Furthermore, the first electrical contact 133a is arranged to extend substantially longitudinally. The first electrical contact 133a is electrically connected to the circuit board 114a. When the atomizer 200a is received within the first receiving cavity 111a, the second electrical contact 222a of the atomizer 200a abuts against or contacts the first electrical contact 133a to form a conductive connection, thereby establishing a conductive connection between the atomizer 200a and the power supply unit 100a.

[0531] In some embodiments, there are two first electrical contacts 133a; the two first electrical contacts 133a are arranged at intervals on both sides of the port of the air intake channel 132a along the thickness direction of the power supply body 100a.

[0604] In an embodiment, when the reservoir 400a is independently removed or replaced from the electronic atomizing device, the slit 451a of the shielding portion 45a is contracted, thereby providing a shield between the first drive interface 424a and the second reservoir 411a to prevent residual liquid matrix inside the second reservoir 411a from flowing out from the exposed first drive interface 424a.

In this second orientation, the electronic atomizing device is inverted, with the outlet 211a of the atomizer 200a facing towards the ground.

[0615] In an embodiment, when the gravity element 46a, such as the gravity ball, is in the open position, the pressure relief channel is opened; and when the gravity element 46a, such as the gravity ball, is in the closed position, the pressure relief channel is closed.

[0616] For example Figure 38 and Figure 45 The diagram shows a schematic of a gravity element 46a, such as a gravity ball, in the open position when the reservoir 400a is in the first orientation. In this embodiment, the gravity element 46a is accommodated or assembled within the pressure relief communication cavity 431a. When the gravity element 46a, such as the gravity ball, is in the open position, the gravity element 46a longitudinally abuts against the sealing element 43a and has a first distance d11 with the cover 42a. Furthermore, when the pressure in the second reservoir 411a is greater than the external pressure, the air in the second reservoir 411a can enter the pressure relief communication cavity 431a, bypass the gravity element 46a, such as the gravity ball, and exit through the pressure relief hole 422a of the cover 42a.

[0617] For example Figure 48 The diagram shows a schematic of a gravity element 46a, such as a gravity ball, moving from an open position to a closed position under the influence of gravity when the reservoir 400a is in the first orientation. The gravity element 46a longitudinally abuts against the cover 42a and blocks and seals the pressure relief hole 422a of the cover 42a, thereby closing the pressure relief channel. At this time, when the pressure inside the second reservoir 411a is greater than the external pressure, the air inside the second reservoir 411a cannot leave through the pressure relief channel, thus preventing pressure relief from being provided to the second reservoir 411a.

[0618] according to Figures 28 to 30 , Figures 39 to 43 As shown, the power supply unit 100a of the electronic atomizing device also includes:

[0619] A fluid transfer mechanism 500a is provided to provide fluid communication between the atomizer 200a, the reservoir 400a, and the drive mechanism 300a.

[0620] In the embodiment, the fluid transport mechanism 500a is arranged substantially perpendicular to the longitudinal direction of the electronic atomizing device; a portion of the fluid transport mechanism 500a is exposed in the first receiving cavity 111a and defines a portion of the bottom surface of the first receiving cavity 111a away from the first end 110a; and a portion of the fluid transport mechanism 500a is exposed in the third receiving cavity 122a and defines a portion of the top surface of the third receiving cavity 122a facing the first end 110a.

[0621] In this embodiment, the fluid transfer mechanism 500a is securely mounted or held on the electronic support 115a. The fluid transfer mechanism 500a is at least partially located between the second receiving cavity 112a and the third receiving cavity 122a.

[0622] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a includes:

[0623] The first support 51a and the second support 52a are joined together; the first support 51a and the second support 52a are prepared separately and then assembled or joined, which is advantageous for the assembly and preparation of the fluid transmission mechanism 500a. In some embodiments, the first support 51a and the second support 52a may be made of flexible silicone, or rigid polymer plastic, ceramic or metal and other materials.

[0624] In the embodiment, the first support 51a is closer to the second side 140a than the second support 52a.

[0625] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a includes:

[0626] The second drive interface 511a is arranged on the first side surface of the first support 51a facing the second receiving cavity 112a; when the drive mechanism 300a is received and installed in the second receiving cavity 112a, the connector 351a of the cylinder element 35a is inserted into the second drive interface 511a for connection.

[0627] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a includes:

[0628] The first connector 512a is located on the second side surface of the first support 51a facing the second end 120a; and after assembly, the first connector 512a extends toward the third receiving cavity 122a. When the reservoir 400a is received and assembled in the third receiving cavity 122a, the first connector 512a is inserted into the first drive interface 424a of the reservoir 400a and passes through the slit 451a of the shielding portion 45a, thereby extending into and communicating with the second reservoir 411a.

[0629] In an embodiment, a first fluid channel 514a is formed or defined within the fluid transfer mechanism 500a, located between the first connector 512a and the second drive interface 511a; the first fluid channel 514a provides fluid communication between the piston cylinder 341a of the drive mechanism 300a and the second liquid storage chamber 411a of the liquid reservoir 400a.

[0630] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a includes:

[0631] A first valve 54a is disposed within a first fluid passage 514a for selectively opening or closing the first fluid passage 514a.

[0632] In this embodiment, the first valve 54a can open the first fluid passage 514a when the gravity element 46a, such as the gravity ball, is in the open position and the user presses the operating element 31a of the drive mechanism 300a to drive the piston 33a to move from a first position to a second position within the cylinder element 35a. This allows air in the piston cylinder 341a to enter the second reservoir chamber 411a of the reservoir 400a through the first fluid passage 514a. Conversely, when the gravity element 46a, such as the gravity ball, is in the closed position, the first valve 54a closes the first fluid passage 514a.

[0633] In this embodiment, the first valve 54a is a check valve or a one-way valve; specifically, the first valve 54a is a check valve that can open the first fluid passage 514a when the pressure difference between the plug cylinder 341a and the second liquid storage chamber 411a exceeds a predetermined threshold. Specifically, the first valve 54a is a silicone check valve; in this embodiment, the first side of the first valve 54a faces the second drive interface 511a, and the second side faces the first connector 512a; when the pressure on the first side of the first valve 54a is greater than the pressure on the second side, and the pressure difference is greater than a predetermined threshold, the first valve 54a bends or deforms toward the first connector 512a, thereby opening the first fluid passage 514a.

[0634] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0635] The second connector 522a is located on the surface of the second support 52a facing the second end 120a; and after assembly, the second connector 522a extends toward the third receiving cavity 122a. When the reservoir 400a is received and assembled in the third receiving cavity 122a, the second connector 522a is inserted into the cavity 421a on the surface of the cover 42a of the reservoir 400a and connected to the liquid output pipe 44a.

[0636] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0637] The third connector 531a is located on the surface of the second support 52a facing the first end 110a; and the third connector 531a is at least partially inserted into or exposed in the first receiving cavity 111a. When the atomizer 200a is received in the first receiving cavity 111a, the third connector 531a is inserted into the first interface 231a of the atomizer 200a, and then fluidly communicates with the first liquid storage cavity 213a through the first conduit 233a.

[0638] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0639] The fourth connector 532a is located on the surface of the second support 52a facing the first end 110a; and the fourth connector 532a is at least partially inserted into or exposed in the first receiving cavity 111. When the atomizer 200a is received in the first receiving cavity 111a, the fourth connector 532a is inserted into the second interface 232a of the atomizer 200a, and then fluidly communicates with the first liquid storage cavity 213a through the second conduit 234a.

[0640] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0641] A second fluid channel is disposed between the second drive interface 511a and the third connector 531a; a portion of the second fluid channel may be located within the first support 51a, and another portion may be located within the second support 52a; for example, the second fluid channel includes a channel portion 513a located within the first support 51a and a channel portion 523a located within the second support 52a. After assembly, the second fluid channel is jointly defined by the channel portion 513a and the channel portion 523a.

[0642] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0643] A second valve 524a is disposed within a second fluid passage for selectively opening or closing the second fluid passage. Specifically, the second valve 524a is disposed between a passage portion 513a within the first support 51a and a passage portion 523a within the second support 52a.

[0644] In an embodiment, the second valve 524a can drive the piston 33a to move from the second position to the first position within the cylinder element 35a according to the elastic element 36a, thereby opening the second fluid channel. This allows the air in the first liquid storage chamber 213a of the atomizer 200a to be drawn into the plug cylinder 341a via the second fluid channel, thereby generating a negative pressure in the first liquid storage chamber 213a of the atomizer 200a.

[0645] In this embodiment, the second valve 524a is a check valve or a one-way valve; specifically, the second valve 524a is a check valve that can open the second fluid channel when the pressure difference between the cylinder 341a and the first liquid storage chamber 213a of the atomizer 200a exceeds a predetermined threshold. Specifically, the second valve 524a is a silicone check valve; in this embodiment, the first side of the second valve 524a faces the second drive interface 511a, and the second side faces the third connector 531a; when the pressure on the first side of the second valve 524a is less than the pressure on the second side, and the pressure difference exceeds a predetermined threshold, the second valve 524a bends or deforms toward the second drive interface 511a, thereby opening the second fluid channel.

[0646] according to Figures 28 to 30 , Figures 39 to 43 As shown, the fluid transfer mechanism 500a also includes:

[0647] The third fluid channel 525a is formed or connected between the second connector 522a and the fourth connector 532a; after assembly, the third fluid channel 525a provides fluid communication between the liquid output pipe 44a of the reservoir 400a and the second pipe 234a of the atomizer 200a.

[0648] Alternatively, in one embodiment, the assembled complete electronic atomizing device may include:

[0649] The first fluid channel is formed or connected between the piston cylinder 341a of the drive mechanism 300a and the second liquid storage chamber 411a of the liquid storage tank 400.

[0650] The second fluid channel is formed or connected between the piston cylinder 341a of the drive mechanism 300a and the first liquid storage chamber 213a of the atomizer 200a.

[0651] The third fluid channel is formed or connected between the second liquid storage chamber 411a of the liquid storage tank 400a and the first liquid storage chamber 213a of the atomizer 200a.

[0652] In this embodiment, the first fluid channel, the second fluid channel, and the third fluid channel are independent of each other. In this embodiment, the first fluid channel can be selectively opened or closed by the first valve 54a. In this embodiment, the second fluid channel can be selectively opened or closed by the second valve 524a. In this embodiment, the third fluid channel is always open.

[0653] See Figures 44 to 47 As shown, in the first orientation where the electronic atomizing device is in the upright position, the user can press or operate the operating element 31a of the drive mechanism 300a to replenish the liquid matrix in the second liquid storage chamber 411a of the liquid reservoir 400a into the first liquid storage chamber 213a of the atomizer 200a. Figures 44 to 47As shown, the gravity element 46a of the reservoir 400a is in the open position with the pressure relief channel open, thus the pressure relief channel is open. Specifically, during the user's operation of pressing the operating element 31a, the flow process of air and liquid matrix within the electronic atomizing device may include:

[0654] S100, such as Figure 44 As indicated by the middle arrow P11, the user presses the operating element 31a, which in turn drives the piston 33a to move from the first position to the second position within the cylinder 341a. During this movement, the elastic element 36a is compressed. As the piston 33a moves, the space within the cylinder 341a is compressed or reduced, thereby driving the first valve 54a to open the first fluid passage 514a. This allows air within the cylinder 341a to enter the second storage chamber 411a of the reservoir 400a via the first fluid passage 514a within the fluid transmission mechanism 500a. Figure 44 As indicated by the middle arrow R41. And according to... Figure 45 As shown, the air entering the second liquid storage chamber 411a of the liquid storage tank 400a will be discharged through the pressure relief channel to the gap between the liquid storage tank 400a and the first housing 10a, and finally flow into the outside atmosphere.

[0655] S200, such as Figure 46 As indicated by the middle arrow P12, after the user releases the pressure on the operating element 31a, the elastic restoring force of the elastic element 36a resets the operating element 31a and the piston 33a, driving the piston 33a to move from the second position to the first position. During the movement of the piston 33a, the space inside the cylinder 341a gradually expands, generating negative pressure, which in turn drives the second valve 524a to open the second fluid channel. This allows the air in the first liquid storage chamber 213a of the atomizer 200a to enter the first pipe 233a through the connecting hole 235a, and then flow through the second fluid channel in the fluid transmission mechanism 500a into the cylinder 341a, as shown in the image. Figure 46 As indicated by the middle arrow R42.

[0656] In this process S200, some of the air in the first liquid storage chamber 213a of the atomizer 200a is drawn into the plug cylinder 341a, thereby creating a negative pressure in the first liquid storage chamber 213a of the atomizer 200a.

[0657] S300, such as Figure 47 As indicated by the middle arrow R43, the negative pressure within the first liquid storage chamber 213a of the atomizer 200a drives the liquid matrix in the second liquid storage chamber 411a of the liquid storage tank 400a to be drawn into the first liquid storage chamber 213a of the atomizer 200a, thereby replenishing the first liquid storage chamber 213a of the atomizer 200a with liquid matrix. Specifically in Figure 47In the liquid matrix transfer path indicated by the middle arrow R43, the liquid matrix in the second liquid storage chamber 411 of the liquid storage tank 400a enters the liquid output pipe 44a through the notch 441a, and then enters the first liquid storage chamber 213a through the third fluid channel 525a in the fluid transfer mechanism 500a and the second pipe 234a of the atomizer 200a.

[0658] In this embodiment, the area of ​​the connecting gap 236a of the second pipe 234a is larger than the area of ​​the connecting hole 235a of the first pipe 233a.

[0659] In an embodiment, the piston 33a has a given travel distance or stroke when the user presses it, thereby driving a predetermined amount of liquid matrix to be drawn from the second reservoir 411a of the reservoir 400a into the first reservoir 213a in each user operation. In some embodiments, the predetermined amount of liquid matrix may be approximately 0.2 to 2 mL.

[0660] Figures 48 to 52 The diagram illustrates that when a user holds the electronic atomizing device in an inverted position (second orientation), the liquid matrix in the first reservoir 213a of the atomizer 200a can be drawn into the cylinder 341a of the drive mechanism 300a by pressing or operating the operating element 31a of the drive mechanism 300a. Figures 48 to 52 As shown, the gravity element 46a of the reservoir 400a is in the closed position with the pressure relief channel closed, thus the pressure relief channel of the reservoir 400a is closed. Specifically, in the second orientation where the electronic atomizing device is in the inverted state, the flow process of air and liquid matrix within the electronic atomizing device when the user presses the operating element 31a may include:

[0661] S100a, such as Figure 49 As indicated by the middle arrow P21, the user presses the operating element 31a, which in turn drives the piston 33a to move from the first position to the second position within the cylinder 341a. During this movement, the elastic element 36a is compressed. As the piston 33a moves, the space within the cylinder 341a is compressed or reduced, driving the first valve 54a to open the first fluid passage 514a. This allows air from the cylinder 341a to enter the second storage chamber 411a of the reservoir 400a via the first fluid passage 514a within the fluid transmission mechanism 500a. Figure 49 As indicated by the middle arrow R51.

[0662] See further Figure 50As indicated by the middle arrow R51, since the pressure relief channel of the liquid reservoir 400a is closed by the gravity element 46a and the liquid matrix in the second liquid reservoir 411a sinks downward, the notch 441a on the end of the liquid output pipe 44a facing the second end 220a is surrounded by air; the air entering the second liquid reservoir 411a of the liquid reservoir 400a flows towards the second end 220a in the form of bubbles, and then enters the liquid output pipe 44a through the notch 441a, and then enters the first liquid reservoir 213a through the third fluid channel 525a in the fluid transmission mechanism 500a and the second pipe 234a of the atomizer 200a.

[0663] See further Figure 51 As indicated by the middle arrow R51, the air entering the first liquid storage chamber 213a creates a positive pressure within it. Driven by this pressure, the air entering the first liquid storage chamber 213a sequentially passes through the first perforation 261a of the first tubular element 26a, the capillary micropores in the capillary element 27a, and the capillary micropores in the porous element 291a before entering the airflow channel and finally being discharged to the outside atmosphere, thus providing pressure relief to the first liquid storage chamber 213a. Figure 51 As shown, when the electronic atomizing device is held in the second orientation in an inverted state, the first perforation 261a of the first tubular element 26a is not sealed or submerged by the liquid matrix in the first liquid storage chamber 213a; at this time, the first perforation 261a of the first tubular element 26a is surrounded by air in the first liquid storage chamber 213a, thereby providing air communication between the first liquid storage chamber 213a and the outside atmosphere.

[0664] S200a, such as Figure 52 As shown by the middle arrow P22, after the user releases the pressure on the operating element 31a, the elastic restoring force of the elastic element 36a resets the operating element 31a and the piston 33a, driving the piston 33a to move from the second position to the first position. During the movement of the piston 33a, the space inside the cylinder 341a gradually expands, generating negative pressure, which in turn drives the second valve 524a to open the second fluid channel; thereby, the liquid matrix in the first liquid storage chamber 213a of the atomizer 200a can be drawn into the first pipe 233a through the connecting hole 235a and the second fluid channel in the fluid transfer mechanism 500a and then into the cylinder 341a for buffering. The flow path of the liquid matrix is ​​as follows: Figure 52 As indicated by the middle arrow R52. Simultaneously, because the liquid matrix in the first liquid storage chamber 213a is drawn into the plug cylinder 341 for buffering, a negative pressure is formed within the first liquid storage chamber 213a, allowing air from the outside atmosphere to flow along... Figure 52As indicated by the middle arrow R53, the liquid enters the first liquid storage chamber 213a after passing through the capillary micropores in the porous body element 291a, the capillary micropores in the capillary element 27a, and the first perforation 261a of the first tubular element 26a, so as to eliminate the negative pressure in the first liquid storage chamber 213a.

[0665] When the user presses the operating element 31a again, the liquid matrix buffered in the plug cylinder 341a can be injected into the second liquid storage chamber 411a of the liquid reservoir 400 through the first fluid channel 514a opened by the first valve 54a.

[0666] In an embodiment, when the electronic atomizing device is in the inverted second orientation, the capillary micropores in the porous element 291a, the capillary micropores in the capillary element 27a, and the first perforation 261a of the first tubular element 26a together define a pressure balance channel connecting the first liquid storage chamber 213a to the outside atmosphere; when... Figure 51 When the pressing operation element 31a shown causes air to be injected into the first liquid storage chamber 213a and become positively pressured, the air in the first liquid storage chamber 213a can be... Figure 51 As indicated by the middle arrow R51, it is discharged from the first tubular element 26a to the outside atmosphere; and, when as Figure 52 When the operating element 31a is reset by the elastic element 36a, causing the liquid matrix in the first liquid storage chamber 213a to be drawn away and resulting in a negative pressure in the first liquid storage chamber 213a, air from the outside atmosphere can enter the first liquid storage chamber 213a through the first tubular element 26a to balance the negative pressure in the first liquid storage chamber 213a. In an embodiment, when the electronic atomizing device is in the second orientation in an inverted state, the first perforation 261a of the first tubular element 26a at least partially provides air communication between the first liquid storage chamber 213a and the outside atmosphere.
