In one embodiment of the present application, the base 15 is provided with a first magnetic member 16, and the first magnetic member 16 is connected to a second magnetic member 31 of the battery assembly 3. In one embodiment of the present application, the first magnetic member 16 and the second magnetic member 31 are magnets or magnetic materials.

[0079] In one embodiment of the present application, the conductive contact 19 is arranged at the center of the base 15, and the number of the first magnetic members 16 is two, and the two first magnetic members 16 are located on both sides of the conductive contact 19.

[0080] In one embodiment of the present application, the atomizer 1 comprises a second sealing member 17, which is located between the first support 12 and the base 15 to prevent leakage of the liquid substrate.

[0081] In an embodiment of the present application, the atomizer 1 comprises a liquid storage member 18 arranged in the first liquid storage cavity 121 for absorbing and storing the liquid substrate. In an embodiment of the present application, the liquid storage member 18 can be made of an elastic organic porous material.

In an embodiment of the present application, the liquid storage member 18 can be a hard cotton.

[0082] An embodiment of the present application provides an aerosol generating device 10 comprising the liquid storage 2, the battery assembly 3 and the atomizer 1 described above. The liquid storage 2 is arranged in the first mounting cavity 111 for providing the liquid substrate to the first liquid storage cavity 121. The battery assembly 3 is arranged in the second mounting cavity 112 for providing the atomizer 1 with electric energy.

[0083] In an embodiment of the present application, the liquid storage 2 comprises a second housing 21 and a second support 22. The second housing 21 and the second support 22 jointly define a second liquid storage cavity 211 for storing the liquid substrate. In an embodiment of the present application, the second housing 21 comprises a fifth clamping portion 212, and the second support 22 comprises a sixth clamping portion 221.

In an embodiment of the present application, the number of the liquid guide columns 222 can be multiple, and the number of the liquid guide holes 223 corresponds to the number of the liquid guide columns 222. In an embodiment of the present application, the number of the liquid guide columns 222 is two. When the liquid substrate in the liquid guide hole 223 of one of the liquid guide columns 222 flows out of the second liquid storage cavity 211, the air pressure in the first liquid storage cavity 121 decreases. At this time, the outside air can enter the second liquid storage cavity 211 through the liquid guide hole 223 of the other liquid guide column 222, thereby preventing the liquid substrate in the second liquid storage cavity 211 from being unable to flow out due to the decrease in air pressure.

[0086] In an embodiment of the present application, the liquid guide hole 223 is arranged on the side wall of the liquid guide column 222. In an embodiment of the present application, the diameter of the liquid guide hole 223 is smaller than the inner diameter of the hollow portion of the liquid guide column 222. The diameter of the liquid guide hole 223 is relatively small compared to the inner diameter of the hollow portion of the liquid guide column 222, so that the liquid matrix flows out of the hollow portion of the liquid guide column 222 at a slower speed, thereby avoiding leakage of the liquid matrix.

[0087] In an embodiment of the present application, the diameter of the liquid guide hole 223 is 0.5mm-1.5mm. In an embodiment of the present application, the shape of the liquid guide hole 223 is a circular, long strip-shaped or other shape opening, and the diameter of the liquid guide hole 155 is 0.5mm-1.5mm, so that the liquid guide hole 155 has a capillary effect, allowing the liquid matrix in the second liquid storage cavity 211 to flow out when the liquid reservoir 2 is in operation; when the liquid reservoir 2 is not in operation, the liquid guide hole 223 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is retained in the liquid guide hole 223, avoiding continuous flow of the liquid matrix when the liquid reservoir 2 is not in operation, thereby preventing leakage of the liquid matrix. In an embodiment of the present application, the diameter of the liquid guide hole 223 can be 0.5mm, 0.8mm, 1.0mm, 1.2mm or 15mm.

[0088] In an embodiment of the present application, the liquid guide hole 223 is arranged on the side wall of the liquid guide column 222.

[0089] In an embodiment of the present application, after the liquid reservoir 2 is installed behind the atomizer 1, the liquid guide column 222 is inserted into the liquid flow channel 123, the liquid guide hole 223 and the liquid flow channel 123 are in communication, and the liquid reservoir 2 can provide the atomizer with liquid matrix. In an embodiment of the present application, the liquid reservoir 2 is installed in front of the atomizer 1, and after the atomizer 1 is injected with liquid matrix, a sealing plug can be used to plug the liquid flow channel 123. In an embodiment of the present application, the liquid reservoir 2 is installed in front of the atomizer 1, and a sealing film is arranged in the second through hole 143 of the first sealing member 14, and when the liquid reservoir 2 is installed in the atomizer 1, the liquid guide column 222 pierces the sealing film, so that the liquid guide hole 223 and the liquid flow channel 123 are in communication.

[0090] In an embodiment of the present application, the battery assembly 3 comprises a second magnetic member 31, and the atomizer 1 and the battery assembly 3 are connected by the first magnetic member 16 and the second magnetic member 31.

[0091] In an embodiment of the present application, the battery assembly 3 comprises an electrode column 33, and the battery assembly 3 is electrically connected to the atomizer 1 by the electrode column 33 and the conductive contact member 19 of the atomizer 1.

[0092] In one embodiment of the application, the battery assembly 3 further comprises a battery 32, which provides electrical power to the atomisation assembly 13. In one embodiment of the application, the battery 32 provides a DC supply voltage in the range of about 2.5 V to about 9.0 V, and the battery 32 can provide a DC current in the range of about 2.5 A to about 20 A.
