[0034] The application provides an aerosol generating device 10 comprising: a liquid storage 1 comprising a first housing 11 defining a first liquid storage cavity 111 for storing a liquid substrate; a device body 2 comprising a second housing 21, a first support 22 disposed in the second housing 21, the first support 22 defining a second liquid storage cavity 221 for storing the liquid substrate, and a liquid storage member 23 filled in at least part of the space of the second liquid storage cavity 221 for receiving and retaining the liquid substrate from the first liquid storage cavity 111; the liquid storage 1 comprises at least one liquid guide column 12 extending outwardly from the first liquid storage cavity 111, the liquid guide column 12 being hollow and having at least one liquid guide hole 121 formed thereon, the first support 22 comprises at least one ring wall 222 defining a receiving cavity 2221 therein, the liquid guide column 12 at least partially extends into the receiving cavity 2221 so that the liquid substrate in the first liquid storage cavity 111 is allowed to pass through the receiving cavity 2221 into the second liquid storage cavity 221, the liquid storage member 23 abuts against an end of the ring wall 222 to seal the receiving cavity 2221, the ring wall 222 has a gas guide passage 2222 avoiding the sealing of the liquid storage member 23, the gas guide passage 2222 provides a path for air to enter the receiving cavity 2221.

[0035] In an embodiment of the application, the ring wall 222 of the device body 2 of the aerosol generating device 10 has the gas guide passage 2222, so that the air in the second liquid storage cavity 221 of the device body 2 can enter the liquid storage 1 through the gas guide passage 2222, avoiding the problem that the air in the device body 2 has to pass through the liquid substrate retained between the liquid guide column 12 and the ring wall 222 or the liquid storage member 23 to enter the liquid storage 1, so that the speed of the liquid substrate of the aerosol generating device 10 from the first liquid storage cavity 111 into the second liquid storage cavity 221 is faster.

[0036] In an embodiment of the present application, the liquid reservoir 1 comprises a mouthpiece assembly 14 connected to the first housing 11 for a user to puff and an air tube 15 connected to the mouthpiece assembly 14 and arranged in the first housing 11 for guiding aerosol into the mouthpiece assembly 14. In an embodiment of the present application, the first housing 11, the mouthpiece assembly 14 and the air tube 15 are integrally formed, one end of the first housing 11 is a closed end connected to the integrally formed mouthpiece assembly 14, and the other end of the first housing 11 is an open end, the liquid reservoir 1 comprises a second support 13 arranged at the open end of the first housing 11, and the liquid guide column 12 is arranged in the second support 13, so that the liquid reservoir 1 can be filled with liquid substrate from the open end and then installed in the second support 13. In an embodiment of the present application, the liquid reservoir 1 comprises a second sealing member 16 arranged between the first housing 11 and the second support 13 for preventing the liquid substrate in the first liquid storage cavity 111 from leaking between the first housing 11 and the second support 13.

[0037] In an embodiment of the present application, one end of the first housing 11 is a closed end connected to the liquid guide column 12, and the other end of the first housing 11 is an open end connected to the detachable mouthpiece assembly 14 and the air tube 15, so that the liquid reservoir 1 can be filled with liquid substrate from the open end and then installed with the mouthpiece assembly 14.

[0038] In an embodiment of the present application, at least a portion of the ring wall 222 protrudes towards the second liquid storage cavity 221, and the ring wall 222 and the liquid reservoir 23 jointly define a first gas cavity 231, the first gas cavity 231 is communicated with the receiving cavity 2221 through the gas guide passage 2222, so that the air in the first gas cavity 231 can enter the receiving cavity 2221 through the gas guide passage 2222, and then enter the first liquid storage cavity 111 from the receiving cavity 2221, so that the liquid substrate in the first liquid storage cavity 111 can quickly enter the second liquid storage cavity 221.

[0039] In an embodiment of the present application, the first housing 11 comprises a first clamping buckle 112, the second housing 21 has a first clamping slot 211, and the first housing 11 and the second housing 21 are connected through the first clamping buckle 112 and the first clamping slot 211. In an embodiment of the present application, the first housing 11 further comprises a first protrusion 113, the second housing 21 has a guide slot 212, and the first housing 11 and the second housing 21 are installed through the first protrusion 113 and the guide slot 212. In an embodiment of the present application, the first housing 11 has a second clamping slot 114, the second support 13 comprises a second clamping buckle 131, and the first housing 11 and the second support 13 are connected through the second clamping slot 114 and the second clamping buckle 131.

[0040] In an embodiment of the present application, the number of liquid guide columns 12 can be multiple, and the number of liquid guide holes 121 corresponds to the number of liquid guide columns 12. In an embodiment of the present application, the number of liquid guide columns 12 is two. When the liquid medium in the liquid guide hole 121 of one of the liquid guide columns 12 flows from the first liquid storage cavity 111 into the second liquid storage cavity 221, the air pressure in the first liquid storage cavity 111 decreases. At this time, the air in the second liquid storage cavity 221 can flow into the first liquid storage cavity 111 through the liquid guide hole 121 of the other liquid guide column 12, thereby preventing the liquid medium in the first liquid storage cavity 111 from flowing into the second liquid storage cavity 221 due to the decrease in air pressure.

[0041] In an embodiment of the present application, the number of ring walls 222 corresponds to the number of liquid guide columns 12. In an embodiment of the present application, the number of liquid guide columns 12 is two, and the number of ring walls 222 is two. In an embodiment of the present application, the first support 22 includes a first ring wall 2223 and a second ring wall 2224. The air guide passage 2222 is arranged in one of the two ring walls 222, so that one of the liquid guide columns 12 of the aerosol generating device 10 and the second ring wall 2224 form a liquid guide-out passage, and the other liquid guide column 12 and the first ring wall 2223 having the air guide passage 2222 form an air guide-in passage, so that the liquid guide-out passage and the air guide-in passage are relatively independent of each other, and do not interfere with each other, thereby ensuring smooth flow of the liquid medium in the liquid reservoir 1. In an embodiment of the present application, both of the two ring walls 222 have the air guide passage 2222, so that the air of the aerosol generating device 10 more easily flows from the first gas cavity 231 into the first liquid storage cavity 111 through the receiving cavity 2221, and the liquid medium more easily and quickly flows from the first liquid storage cavity 111 into the second liquid storage cavity 221.

[0042] In an embodiment of the present application, the liquid guide hole 121 is arranged in the side wall of the liquid guide column 12. In an embodiment of the present application, the diameter of the liquid guide hole 121 is smaller than the inner diameter of the hollow portion of the liquid guide column 12. The diameter of the liquid guide hole 121 is relatively small with respect to the inner diameter of the hollow portion of the liquid guide column 12, so that the liquid medium flows out of the hollow portion of the liquid guide column 12 at a slower speed, thereby avoiding leakage of the liquid medium from the atomization assembly 24 after too much liquid medium remains in the liquid storage member 23 of the second liquid storage cavity 221.

[0043] In an embodiment of the present application, the diameter of the liquid guide hole 121 is 0.5mm-1.5mm. In an embodiment of the present application, the liquid guide hole 121 is a circular, long strip or other shape opening, and the diameter of the liquid guide hole 121 is 0.5mm-1.5mm, so that the liquid guide hole 121 has a capillary effect. When the aerosol generating device 10 is being puffed by a user, the air pressure in the second liquid storage cavity 221 decreases, and the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid substrate in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guide column 12; when the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage cavity 111 and the second liquid storage cavity 221 remains balanced, the liquid guide hole 121 has a certain capillary effect on the liquid substrate therein, and the liquid substrate is kept in the liquid guide hole 121, avoiding the continuous entry of the liquid substrate into the second liquid storage cavity 221 when the aerosol generating device 10 is not in operation, so that the liquid substrate leaks through the atomization assembly 24. In an embodiment of the present application, the diameter of the liquid guide hole 121 can be 0.5mm, 0.8mm, 1.0mm, 1.2mm, 15mm.

[0044] In an embodiment of the present application, the distance between the outer side wall of the liquid guide column 12 and the inner side wall of the ring wall 222 is between 0.1mm-1.0mm. At this time, the outer side wall of the liquid guide column 12 and the inner side wall of the ring wall 222 also have a capillary effect. When the aerosol generating device 10 is being puffed by a user, the air pressure in the second liquid storage cavity 221 decreases, and the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid substrate in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guide column 12; when the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage cavity 111 and the second liquid storage cavity 221 remains balanced, the outer side wall of the liquid guide column 12 and the inner side wall of the ring wall 222 have a certain capillary effect on the liquid substrate therein, and the liquid substrate is kept between the outer side wall of the liquid guide column 12 and the inner side wall of the ring wall 222, avoiding the continuous entry of the liquid substrate into the second liquid storage cavity 221 when the aerosol generating device 10 is not in operation, so that the liquid substrate leaks through the atomization assembly 24. In an embodiment of the present application, the distance between the outer side wall of the liquid guide column 12 and the inner side wall of the ring wall 222 can be 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm.

[0045] In an embodiment of the present application, the liquid guide column 12 abuts against the liquid storage piece 23.

[0046] In an embodiment of the present application, the distance between the liquid guide column 12 and the liquid storage member 23 is 0.1mm-1.0mm. In this case, the liquid guide column 12 and the liquid storage member 23 also have a capillary effect. When the aerosol generating device 10 is being puffed by a user, the air pressure in the second liquid storage cavity 221 decreases, while the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid substrate in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guide column 12. When the aerosol generating device 10 is not in operation, the air pressure in the first liquid storage cavity 111 and the second liquid storage cavity 221 remains balanced, and the liquid guide column 12 and the liquid storage member 23 have a certain capillary effect on the liquid substrate therebetween, so that the liquid substrate is kept between the liquid guide column 12 and the liquid storage member 23, avoiding the continuous entry of the liquid substrate into the second liquid storage cavity 221 when the aerosol generating device 10 is not in operation, so that the liquid substrate is prevented from leaking through the atomization assembly 24. In an embodiment of the present application, the distance between the liquid guide column 12 and the liquid storage member 23 can be 0.1mm, 0.2mm, 0.4mm, 0.6mm, 0.8mm, or 1.0mm.

[0047] In an embodiment of the present application, the device body 2 comprises a liquid storage member 23 made of a capillary core material, and the liquid substrate in the second liquid storage cavity 221 is wholly or partially received or kept by the liquid storage member 23, so that the liquid substrate in the second liquid storage cavity 221 is not easy to leak through the atomization assembly 24 during the transportation or standing of the aerosol generating device 10 or the device body 2, and a better taste can be obtained at the initial stage of puffing when the user uses the aerosol generating device 10. In an embodiment of the present application, the liquid storage member 23 can be made of an elastic organic porous material, and the liquid storage member 23 can have a hardness or flexibility between the generally flexible plant cotton / non-woven fabric (having a Shore hardness less than 20A) and the rigid porous ceramic / microporous metal (having a Shore hardness greater than 80A), so that the structure is stable and has very low expansion after absorbing and infiltrating the liquid substrate, and also has a certain hardness, so that it can be easily fixed and kept.

[0048] In an embodiment of the present application, one end of the ring wall 222 abuts against the liquid storage member 23, and the other end is connected to the first support 22, so that the ring wall 222 surrounds a receiving cavity 2221 for receiving the liquid substrate, and the ring wall 222 has a gas guiding passage 2222, so that the receiving cavity 2221 and the gas cavity in the second liquid storage cavity 221 are in communication, thereby facilitating the air in the second liquid storage cavity 221 to pass through the gas guiding passage 2222 of the ring wall 222 and then enter the first liquid storage cavity 111 through the receiving cavity 2221, ensuring the air pressure balance between the first liquid storage cavity 111 and the second liquid storage cavity 221, so that the liquid substrate in the aerosol generating device 10 can enter the second liquid storage cavity 221 from the first liquid storage cavity 111 at a faster speed.

In one embodiment of the present application, the minimum width size of the air guide passage 2222 is 0.1mm-1.0mm. In one embodiment of the present application, the minimum aperture size of the air guide passage 2222 is 0.1mm-1.0mm.
