[0050] One embodiment of the present application provides an aerosol generating device 10, as shown in Figures 1-5, comprising: a liquid reservoir 1, comprising a first shell 11, wherein the first shell 11 defines a first liquid storage chamber 12 for storing a liquid matrix; a device body 2, comprising a second shell 21, wherein the second shell 21 defines a second liquid storage chamber 22 for storing a liquid matrix; a liquid storage member 23, which fills at least a portion of the space in the second liquid storage chamber 22 and is used to receive and retain the liquid matrix from the first liquid storage chamber 12; an atomizing assembly 3, which is disposed in the second shell 21 and adjacent to the second shell 21; The liquid storage chamber 22 is used to atomize the liquid matrix retained in the liquid storage member 23 to generate an aerosol. A fluid channel 123 is provided between the first liquid storage chamber 12 and the second liquid storage chamber 22 to connect the two. The fluid channel 123 is configured to have an open state and a closed state. When the fluid channel 123 is in the closed state, the liquid matrix in the first liquid storage chamber 12 is prevented from entering the second liquid storage chamber 22. When the fluid channel 123 is in the open state, the liquid matrix in the first liquid storage chamber 12 is allowed to enter the second liquid storage chamber 22 and be absorbed by the liquid storage member 23.

[0051] The present application provides a first liquid storage chamber 12 and a second liquid storage chamber 22, with a liquid storage member 23 provided adjacent to the second liquid storage chamber 22 of the atomizer assembly 3. This allows the liquid matrix in the second liquid storage chamber 22 to be adsorbed and retained on the liquid storage member 23, making it less likely to leak when the aerosol generating device 10 is stationary or transported. Furthermore, during inhalation, the liquid matrix in the liquid storage member 23 can enter the atomizer assembly 3 in a timely manner, avoiding dry burning and maintaining a good taste. Furthermore, the first liquid storage chamber 12 and the second liquid storage chamber 22 can be connected via a fluid channel 123, allowing the liquid matrix in the second liquid storage chamber 22 to be absorbed and retained by the liquid storage member 23 without leaking. At the same time, the liquid matrix in the first liquid storage chamber 12 can replenish the liquid matrix in the second liquid storage chamber 22, giving the aerosol generating device 10 a larger overall capacity.

[0052] In one embodiment of the present application, the liquid reservoir 1 includes a first shell 11 and an air tube 13, and the device body 2 includes a second shell 21, a liquid storage member 23, a bracket 24, and a support tube 25. The bracket 24, the first shell 11, and the second shell 21 cooperate to form the exterior surface of the aerosol generating device 10. The bracket 24 is snapped onto the second shell 21. One end of the air tube 13 is connected to the first shell 11, and the other end of the air tube 13 is movably connected to the bracket 24. The first shell 11, the bracket 24, and the air tube 13 together form a first liquid storage chamber 12; the support tube 25 is embedded in the bracket 24, and the bracket 24, the support tube 25, and the atomizing assembly 3 together form a second liquid storage chamber 22. In one embodiment of the present application, the relative movement of the first shell 11 and the second shell 21 can drive the relative movement of the air tube 13 and the bracket.

[0053] In one embodiment of the present application, the first housing 11 and the second housing 21 have a first position and a second position. As shown in FIG1 , when the first housing 11 and the second housing 21 are in the first position, the fluid channel 123 is closed, and the liquid matrix is ​​prevented from entering the second liquid storage chamber 22. As shown in FIG2 and FIG3 , when the first housing 11 and the second housing 21 are in the second position, the fluid channel 123 is opened, and the liquid matrix in the first liquid storage chamber 12 is allowed to enter the second liquid storage chamber 22 and be absorbed by the liquid storage member 23. In one embodiment of the present application, the first housing 11 and the second housing 21 are movably connected, so that the relative position of the first housing 11 and the second housing 21 can be changed, thereby driving the fluid channel 123 to open or close, so that the liquid matrix in the first liquid storage chamber 12 can replenish the liquid matrix in the second liquid storage chamber 22, thereby increasing the overall capacity of the aerosol generating device 10. In one embodiment of the present application, when the user needs to use the aerosol generating device 10 for inhalation, the user can change the relative positions of the first shell 11 and the second shell 21 so that the shell 1 is in the second position, the fluid channel 123 is opened, and the liquid matrix in the first liquid storage chamber 12 is allowed to enter the second liquid storage chamber 22 and be absorbed by the liquid storage member 23; when the user does not need to use the aerosol generating device 10 for inhalation, the user can change the relative positions of the first shell 11 and the second shell 21 so that the shell 1 is in the first position, the fluid channel 123 is closed, and the liquid matrix is ​​prevented from entering the second liquid storage chamber 22, thereby preventing the liquid matrix from leaking when the aerosol generating device 10 is not working.

[0054] In one embodiment of the present application, the liquid reservoir 23 fills at least a portion of the second liquid reservoir 22, and is used to receive and retain the liquid matrix from the first liquid reservoir 12. In one embodiment of the present application, the liquid reservoir 23 completely fills the second liquid reservoir 22, and the liquid matrix in the first liquid reservoir 12 is absorbed by the liquid reservoir 23 upon entering the second liquid reservoir 22. In one embodiment of the present application, the liquid reservoir 23 partially fills the second liquid reservoir 22, and a portion of the liquid matrix entering the second liquid reservoir 22 from the first liquid reservoir 12 is absorbed by the liquid reservoir 23, while the remaining portion is distributed in the space of the second liquid reservoir 22 not filled with liquid matrix. The liquid matrix in the second liquid reservoir 22 is fully or partially received or retained by the liquid reservoir 23, which prevents the liquid matrix in the second liquid reservoir 22 from leaking through the atomizer assembly 3 during transportation or storage of the aerosol generating device 10. Furthermore, when a user uses the aerosol generating device 10, a better taste is obtained during the initial puff.

[0055] In one embodiment of the present application, the liquid storage member 23 can be made of an elastic organic porous material. The liquid storage member 23 has a hardness between that of conventional flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A). After absorbing and soaking in a liquid matrix, the liquid storage member 23 has extremely low expansion, thus having a relatively stable structural shape, which can be easily fixed and maintained. As an alternative example, the liquid storage member 23 can be artificial or natural fiber cotton.

[0056] In one embodiment of the present application, the atomizer assembly 3 is embedded in the support tube 25. As shown in FIG8 , the atomizer assembly 3 includes a liquid guide 31 and a heating element 32. The liquid guide 31 has a liquid guide surface 311 and a heating surface 312 arranged opposite to each other. The liquid guide surface 311 is arranged opposite to the liquid storage member 23 and is in fluid communication with the second liquid storage chamber 22. The liquid guide 31 guides the liquid matrix from the liquid guide surface 311 to the heating surface 312. One side of the heating surface 312 is the atomization chamber 33. The liquid matrix is ​​heated by the heating element 32 on the heating surface 312, and atomized to generate an aerosol that enters the atomization chamber 33. The support tube 25 and the air pipe 13 are connected by an interference fit, so that the aerosol generated by heating the liquid matrix on the heating surface 312 of the liquid guide 31 can enter the air pipe 13 from the atomization chamber 33, thereby being inhaled by the user. The support tube 25 is further provided with a liquid guide port 251 . The liquid guide port 251 fluidically connects the second liquid storage chamber 22 and the liquid guide member 31 . The liquid matrix in the second liquid storage chamber 22 can enter the liquid guide member 31 through the liquid guide port 251 .

[0057] In one embodiment of the present application, the liquid guide member 31 of the atomizer assembly 3 is distributed within the support tube 25 and extends along the axial direction of the support tube 25. The heating element 32 is attached to the heating surface 312 of the liquid guide member 31. For example, the heating element 32 can be bonded to the surface of the liquid guide member 31 by printing, deposition, sintering, or physical assembly. In one embodiment of the present application, the heating element 32 is a mesh heating network, and the liquid guide member 31 is porous ceramic.

[0058] In one embodiment of the present application, the atomizer assembly 3 further includes a conductive pin 34, and the heating element 32 is electrically connected to the battery assembly 7 and the circuit board assembly 8 of the aerosol generating device 10 through the conductive pin 34. The battery assembly 7 is used to provide electrical energy to the aerosol generating device 10, and the circuit board assembly 8 can control the current and voltage supplied by the battery assembly 7 to the atomizer assembly 3 and control the heating state of the atomizer assembly 3. The heating element 32 includes a first heating element 321 and a second heating element 322. The heating state of the first heating element 321 and the second heating element 322 is controlled by the circuit board assembly 8. For example, the first heating element 321 and the second heating element 322 can be heated at the same time, so that the liquid matrix of the heating surface 312 is atomized faster; only one of the first heating element 321 or the second heating element 322 can be in a heating state to avoid the heating element 32 from heating too fast and causing dry burning; the first heating element 321 and the second heating element 322 are heated separately at the beginning of the user's inhalation, heated together in the middle, and heated separately in the later stage to avoid dry burning of the heating element 32. In other embodiments, the working states of the first heating element 321 and the second heating element 322 can also be set according to specific circumstances.

[0059] In one embodiment of the present application, as shown in Figures 1-6, the liquid reservoir 1 includes a first valve body 4, which is positioned between the first liquid storage chamber 12 and the second liquid storage chamber 22. The first valve body 4 includes a sealing portion 41 and a liquid guide column 42. The sealing portion 41 is used to separate the first liquid storage chamber 12 from the second liquid storage chamber 22, and the liquid guide column 42 is provided with a liquid guide hole 43. The liquid reservoir 1 includes at least one liquid guide column 42 extending outward from the first liquid storage chamber 12. The liquid guide column 42 is hollow and has at least one liquid guide hole 43 defined therein. When the first housing 11 is in the second position, the liquid guide column 42 is at least partially inserted into the second liquid storage chamber 22, so that the liquid guide hole 43 communicates with the second liquid storage chamber 22. The liquid reservoir 1 also includes a first sealing member 51 movably connected to the liquid guide column 42. When the first housing 11 is in the first position, the first sealing member 51 seals the liquid guide hole 43. The liquid guide hole 43 allows the liquid matrix in the first liquid storage chamber 12 to flow into the second liquid storage chamber 22. In one embodiment of the present application, the first valve body 4 is clamped between the first shell 11 and the air pipe 13, and the first valve body 4 is provided with a first vent 44, and the air pipe 13 and the atomization chamber 33 are connected to each other through the first vent 44. In one embodiment of the present application, the first shell 11 and the second shell 21 are roughly cylindrical, the first liquid storage chamber 12 and the second liquid storage chamber 22 are also roughly cylindrical, and the sealing portion 41 of the first valve body 4 is roughly annular in the axial direction of the aerosol generating device 10. In one embodiment of the present application, the liquid guide column 42 is a hollow cylindrical body protruding from the sealing portion 41, and the liquid guide column 42 has a liquid guide cavity 421. The liquid guide cavity 421 is in fluid communication with the first liquid storage chamber 12, and the liquid guide cavity 421 is filled with a liquid matrix. The liquid guide cavity 421 can be in fluid communication with the second liquid storage chamber through the liquid guide hole 43. When the liquid guide hole 43 is closed, the liquid matrix in the liquid guide cavity 421 is prevented from entering the second liquid storage cavity 22 ; when the liquid guide hole 43 is open, the liquid matrix in the liquid guide cavity 421 is allowed to enter the second liquid storage cavity 22 and thus be absorbed by the liquid storage member 23 .

[0060] In one embodiment of the present application, there may be multiple liquid-conducting columns 42, and the number of liquid-conducting holes 43 corresponds to the number of liquid-conducting columns 42. In one embodiment of the present application, there are two liquid-conducting columns 42, and the number of liquid-conducting holes 43 is also two. In another embodiment of the present application, there may be three liquid-conducting columns 42, and the number of liquid-conducting holes 43 is also three. In another embodiment of the present application, there may be four liquid-conducting columns 42, and the number of liquid-conducting holes 43 is also four. In one embodiment of the present application, there are two liquid-conducting columns 42. When the liquid matrix in the liquid-conducting hole 43 of one liquid-conducting column 42 enters the second liquid-conducting chamber 22 from the liquid-conducting cavity 421, the air pressure in the first liquid-conducting chamber 12 decreases. At this time, air in the second liquid-conducting chamber 22 can enter the first liquid-conducting chamber 12 through the liquid-conducting hole 43 of the other liquid-conducting column 42, thereby preventing the liquid matrix in the first liquid-conducting chamber 12 from being unable to enter the second liquid-conducting chamber 22 due to the decrease in air pressure.

[0061] In one embodiment of the present application, a liquid guide hole 43 is provided on the sidewall of the liquid guide column 42. In one embodiment of the present application, the diameter of the liquid guide hole 43 is smaller than the inner diameter of the hollow portion of the liquid guide column 42. The smaller diameter of the liquid guide hole 43 relative to the inner diameter of the hollow portion of the liquid guide column 42 slows down the flow of the liquid matrix from the hollow portion of the liquid guide column 42, thereby preventing the liquid matrix from leaking from the atomizer assembly 3 after the liquid storage member 23 of the second liquid storage chamber 22 retains an excessive amount of liquid matrix.

[0062] In one embodiment of the present application, the aperture or diameter of the liquid guide hole 43 is 0.5 mm to 1.5 mm. In one embodiment of the present application, the shape of the liquid guide hole 43 is a circular, elongated or other shaped opening, and the aperture or diameter of the liquid guide hole 43 is 0.5 mm to 1.5 mm, so that the liquid guide hole 43 has a capillary effect. When the aerosol generating device 10 is inhaled by the user, the air pressure in the second liquid storage chamber 22 decreases, and the air pressure in the first liquid storage chamber 12 remains unchanged, so that the liquid matrix in the first liquid storage chamber 12 enters the second liquid storage chamber 22 through the first valve body 4; when the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage chamber 12 and the second liquid storage chamber 22 remain balanced, and the liquid guide hole 43 has a certain capillary effect on the liquid matrix therein, so that the liquid matrix is ​​retained in the liquid guide hole 43, thereby preventing the liquid matrix from continuously entering the second liquid storage chamber 22 when the aerosol generating device 10 is not in operation, thereby preventing the liquid matrix from leaking through the atomizer assembly 3. In one embodiment of the present application, the aperture or diameter of the liquid guide hole may be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, or 15 mm.

[0063] In one embodiment of the present application, the distance between the outer wall of the liquid-guiding column 42 and the inner wall of the bracket 24 is 0.1 mm to 1.0 mm. At this time, there is also a capillary effect between the outer wall of the liquid-guiding column 42 and the bracket 24. When the aerosol generating device 10 is inhaled by the user, the air pressure in the second liquid storage chamber 22 decreases, while the air pressure in the first liquid storage chamber 12 remains unchanged, so that the liquid matrix in the first liquid storage chamber 12 enters the second liquid storage chamber 22 through the first valve body 4; when the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage chamber 12 and the second liquid storage chamber 22 remains balanced, and there is a certain capillary effect between the outer wall of the liquid-guiding column 42 and the bracket 24 on the liquid matrix therein, so that the liquid matrix is ​​retained between the outer wall of the liquid-guiding column 42 and the bracket 24, thereby preventing the liquid matrix from continuously entering the second liquid storage chamber 22 when the aerosol generating device 10 is not in operation, thereby preventing the liquid matrix from leaking through the atomizer assembly 3. In one embodiment of the present application, the distance between the outer wall of the liquid-guiding column 42 and the inner wall of the bracket 24 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1.0 mm.

[0064] In one embodiment of the present application, the distance between the outer wall of the liquid-guiding column 42 and the outer wall of the liquid storage member 23 is 0.1 mm to 1.0 mm. Similarly, a capillary effect exists between the outer wall of the liquid-guiding column 42 and the outer wall of the liquid storage member 23. When the aerosol generating device 10 is inhaled by the user, the air pressure in the second liquid storage chamber 22 decreases, while the air pressure in the first liquid storage chamber 12 remains unchanged, allowing the liquid matrix in the first liquid storage chamber 12 to enter the second liquid storage chamber 22 through the first valve body 4. When the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage chamber 12 and the second liquid storage chamber 22 remains balanced. The outer wall of the liquid-guiding column 42 and the outer wall of the liquid storage member 23 have a certain capillary effect on the liquid matrix therein, and the liquid matrix is ​​retained between the outer wall of the liquid-guiding column 42 and the outer wall of the liquid storage member 23. This prevents the liquid matrix from continuously entering the second liquid storage chamber 22 when the aerosol generating device 10 is not in operation, thereby preventing the liquid matrix from leaking through the atomizer assembly 3. In one embodiment of the present application, the distance between the outer wall of the liquid guiding column 42 and the outer wall of the liquid storage component 23 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1.0 mm.

[0065] In one embodiment of the present application, the sealing portion 41 and the liquid guiding column 42 of the first valve body 4 are integrally formed, which is beneficial to improving the sealing performance of the liquid guiding cavity 421, so that liquid can be conducted between the first liquid storage cavity 12 and the second liquid storage cavity 22 only when the liquid guiding hole 43 is connected. When the liquid guiding hole 43 is closed, the liquid matrix in the liquid guiding cavity 421 is prevented from entering the second liquid storage cavity 22.

When a user inhales from the aerosol generating device 10, the liquid matrix in the second liquid storage chamber 22 is consumed. At this point, the air pressure in the first gas chamber 2461 and the second gas chamber 2462 decreases, and the gas in the trachea 13 can enter the first gas chamber 2461 or the second gas chamber 2462 along the first air channel 244, thereby balancing the air pressure in the first gas chamber 2461 or the second gas chamber 2462 with the air pressure in the trachea 13. Simultaneously, the air pressure in the first gas chamber 2461 and the second gas chamber 2462 can be balanced via the second air channel 245, thereby balancing the air pressure on both sides of the liquid storage member 23.
