[0055] An embodiment of the present application provides an aerosol generating device 10, such as Figure 1-5The device includes: a liquid reservoir 1, including a first shell 11, in which a first liquid storage chamber 12 for storing a liquid matrix is ​​defined; a device body 2, including a second shell 21, in which a second liquid storage chamber 22 for storing a liquid matrix is ​​defined; a liquid storage member 23, which is filled in at least part of the space of the second liquid storage chamber 22, and is used to receive and retain the liquid matrix from the first liquid storage chamber 12; an atomization assembly 3, which is arranged in the second shell 21 and adjacent to the second liquid storage chamber 22, and is used to atomize the liquid matrix retained in the liquid storage member 23, so as to generate an aerosol; wherein a fluid channel 123 is provided between the first liquid storage chamber 12 and the second liquid storage chamber 22 to connect the two, and the fluid channel 123 is configured to have an open state and a closed state; when the fluid channel 123 is in a closed state, the liquid matrix in the first liquid storage chamber 12 is prevented from entering the second liquid storage chamber 22, and when the fluid channel 123 is in an open state, the liquid matrix in the first liquid storage chamber 12 is allowed to enter the second liquid storage chamber 22 and is absorbed by the liquid storage member 23.

[0056] The present application sets a first liquid storage chamber 12 and a second liquid storage chamber 22, and a liquid storage part 23 is provided in the second liquid storage chamber 22 adjacent to the atomizer assembly 3, so that the liquid matrix in the second liquid storage chamber 22 is adsorbed and retained on the liquid storage part 23, and is not easy to leak when the aerosol generating device 10 is stationary or transported; and when sucking, the liquid matrix in the liquid storage part 23 can enter the atomizer assembly 3 in time to avoid dry burning and maintain a good taste. In addition, the first liquid storage chamber 12 and the second liquid storage chamber 22 can be connected through the fluid channel 123, so that the liquid matrix in the second liquid storage chamber 22 is absorbed and retained by the liquid storage part 23 without leaking. At the same time, the liquid matrix in the first liquid storage chamber 12 can supplement the liquid matrix in the second liquid storage chamber 22, so that the aerosol generating device 10 has a larger capacity as a whole.

[0057] 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 part 23, a bracket 24, and a support tube 25. The bracket 24, the first shell 11 and the second shell 12 cooperate to form the appearance surface of the aerosol generating device 10. The bracket 24 is snapped to the second shell 12, 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 atomization 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 12 can drive the relative movement of the air tube 13 and the bracket.

[0058] In one embodiment of the present application, the first housing 11 and the second housing 21 have a first position and a second position. Figure 1When the first shell 11 and the second shell 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; Figure 2 and Figure 3 As shown, when the first shell 11 and the second shell 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 is absorbed by the liquid storage member 23. In one embodiment of the present application, the first shell 11 and the second shell 12 are movably connected, so that the relative positions of the first shell 11 and the second shell 12 change, thereby driving the fluid channel 123 to open or close, so that the liquid matrix in the first liquid storage chamber 12 can supplement the liquid matrix in the second liquid storage chamber 22, so that the aerosol generating device 10 as a whole has a larger capacity. 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 12 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 shell changes the relative positions of the first shell 11 and the second shell 12 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.

[0059] In one embodiment of the present application, the liquid storage member 23 is filled in at least part of the space of the second liquid storage chamber 22, and is used to receive and retain the liquid matrix from the first liquid storage chamber 12. In one embodiment of the present application, the liquid storage member 23 fills the second liquid storage chamber 22 completely, and the liquid matrix in the first liquid storage chamber 12 is absorbed by the liquid storage member 23 after entering the second liquid storage chamber 22. In one embodiment of the present application, the liquid storage member 23 fills part of the space of the second liquid storage member 112, and part of the liquid matrix entering the second liquid storage chamber 22 from the first liquid storage chamber 12 is absorbed by the liquid storage member 23, and the other part is distributed in the space of the second liquid storage chamber 22 that is not filled with the liquid matrix. The liquid matrix in the second liquid storage chamber 22 is fully or partially received or retained by the liquid storage member 23, so that the liquid matrix in the second liquid storage chamber 22 is not easy to leak through the atomizer assembly 3 during the transportation or stationary process of the aerosol generating device 10; and a better taste can be obtained at the initial stage of inhalation when the user uses the aerosol generating device 10.

[0060] 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 can have a hardness or flexibility between that of ordinary flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A), so that the structure is stable and has extremely low expansion after absorbing and infiltrating the liquid matrix, and has a certain hardness that can be easily fixed and maintained. In one embodiment of the present application, the liquid storage member 23 can be hard artificial cotton. In one embodiment of the present application, the atomization component 3 is embedded in the support tube 25, such as Figure 8 As shown, the atomization 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 element 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 aerosol is generated by atomization and 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, so as to be inhaled by the user. The support tube 25 is further provided with a liquid guide port 251 , and the liquid guide port 251 fluidly connects the second liquid storage chamber 22 and the liquid guide member 31 , so that the liquid matrix in the second liquid storage chamber 22 can enter the liquid guide member 31 through the liquid guide port 251 .

[0061] In one embodiment of the present application, the liquid guide member 31 of the atomizer assembly 3 is distributed in the support tube 25 along the axial extension of the support tube 25, and 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 combined with 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 net, and the liquid guide member 31 is a porous ceramic.

[0062] 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, and the first heating element 321 and the second heating element 322 are controlled by the circuit board assembly 8 to control the heating state. 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 initial stage of the user's inhalation, heated together in the middle stage, 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.

[0063] In one embodiment of the present application, Figure 1-5As shown, the liquid reservoir 1 includes a first valve body 4, which is located 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 and 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, and the liquid guide column 42 is hollow and has at least one liquid guide hole 43 formed thereon; 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 41 that can be movably connected to the liquid guide column 42, and the first sealing member 41 closes the liquid guide hole when the first housing 11 is in the first position, and 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 gas-conducted through the first vent 44. In one embodiment of the present application, the first shell 11 and the second shell 12 are roughly cylindrical, the first liquid storage chamber 12 and the second liquid storage chamber 22 are also roughly cylindrical, and the projection of the sealing portion 41 of the first valve body 4 in the axial direction of the aerosol generating device 10 is roughly annular. In one embodiment of the present application, the liquid guide column 42 is a hollow columnar body protruding from the sealing portion 41, and the liquid guide column 42 has a liquid guide cavity 421, and the liquid guide cavity 421 is fluid-conducted 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 fluid-conducted with the second liquid storage chamber through the liquid guide hole 43. When the liquid conducting hole 43 is closed, the liquid matrix in the liquid conducting cavity 421 is prevented from entering the second liquid storage cavity 22 ; when the liquid conducting hole 43 is open, the liquid matrix in the liquid conducting cavity 421 is allowed to enter the second liquid storage cavity 22 and thus be absorbed by the liquid storage member 23 .

[0064] In one embodiment of the present application, the number of liquid-conducting columns 42 may be multiple, and the number of liquid-conducting holes 43 corresponds to the number of liquid-conducting columns 42. In one embodiment of the present application, the number of liquid-conducting columns 42 is two, and the number of liquid-conducting holes 43 is also two. In another embodiment of the present application, the number of liquid-conducting columns 43 may be three, and the number of liquid-conducting holes 43 is also three. In another embodiment of the present application, the number of liquid-conducting columns 43 may be four, and the number of liquid-conducting holes 43 is also four. In one embodiment of the present application, the number of liquid-conducting columns 42 is two, and when the liquid matrix in the liquid-conducting hole 43 of one of the liquid-conducting columns 42 enters the second liquid storage chamber 22 from the liquid-conducting cavity 421, the air pressure in the first liquid storage chamber 12 decreases, and at this time, the air in the second liquid storage chamber 22 can enter the first liquid storage chamber 12 through the liquid-conducting hole 43 of another liquid-conducting column 42, thereby preventing the liquid matrix in the first liquid storage chamber 12 from being unable to enter the second liquid storage chamber 22 due to the reduction in air pressure.

[0065] In one embodiment of the present application, the liquid guiding hole 43 is disposed on the side wall of the liquid guiding column 42. In one embodiment of the present application, the diameter of the liquid guiding hole 43 is smaller than the inner diameter of the hollow portion of the liquid guiding column 42. The diameter of the liquid guiding hole 43 is smaller than the inner diameter of the hollow portion of the liquid guiding column 42, so that the liquid matrix flows out of the hollow portion of the liquid guiding column 42 at a slower speed, thereby preventing the liquid matrix from leaking from the atomization assembly 3 after the liquid storage member 23 of the second liquid storage chamber 22 retains too much liquid matrix.

[0066] In one embodiment of the present application, the aperture or diameter of the liquid guide hole 43 is 0.5mm-1.5mm. 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 0.5mm-1.5mm, 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 a working state, the air pressure in the first liquid storage chamber 12 and the second liquid storage chamber 22 is kept balanced, and the liquid guide hole 43 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is ​​kept in the liquid guide hole 43, which prevents the liquid matrix from continuously entering the second liquid storage chamber 22 when the aerosol generating device 10 is not working, thereby causing the liquid matrix to leak through the atomizing 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.
