In an embodiment of the present application, the liquid output member 13 defines a first accommodation chamber 131. The liquid reservoir 1 includes a first seal 31, and the first seal 31 is disposed in the first accommodation chamber 131.

When the liquid storage cavity 1 is inserted into the main body 22, the convex rib 114 first inserts along the longitudinal guiding groove 2211, and then the first housing 11 and the second housing 221 are rotated relative to each other, and the convex rib 114 can be assembled in place along the circumferential guiding groove 2212.

[0101] In an embodiment of the present application, after the liquid storage device 1 is loaded into the device main body 2 or the liquid storage device 1 and the atomizer 21 are loaded into the main body, the first housing 11 and the base 12 of the liquid storage device 1 are fixedly connected. The liquid output member 13 of the liquid storage device 1 is positioned on the first bracket 212 through the first positioning post 134. The first bracket 212 and the second bracket 216 are fixedly connected, and the second bracket 216 and the second housing 221 are fixedly connected.

[0102] In an embodiment of the present application, the aerosol generating device 10 further includes at least one liquid guiding column 5. The liquid guiding column 5 is hollow and is provided with at least one liquid guiding hole 51, and the liquid guiding hole 51 communicates with the liquid outlet 121.

In one embodiment of the present application, the number of the liquid-conducting columns 5 is two, and when the liquid matrix in the liquid-conducting hole 51 of one of the liquid-conducting columns 5 enters the second liquid-conducting chamber 211 from the first liquid-conducting chamber 111, the air pressure in the first liquid-conducting chamber 111 decreases, and at this time, the air in the second liquid-conducting chamber 211 can enter the first liquid-conducting chamber 211 through the liquid-conducting hole 51 of another liquid-conducting column 5, thereby preventing the liquid matrix in the first liquid-conducting chamber 111 from being unable to enter the second liquid-conducting chamber 211 due to the decrease in air pressure.

[0104] In one embodiment of the present application, the liquid guiding hole 51 is disposed on the side wall of the liquid guiding column 5. In one embodiment of the present application, the diameter of the liquid guiding hole 51 is smaller than the inner diameter of the hollow portion of the liquid guiding column 5. The diameter of the liquid guiding hole 51 is smaller than the inner diameter of the hollow portion of the liquid guiding column 5, so that the liquid matrix flows out of the hollow portion of the liquid guiding column 5 at a slower speed, thereby preventing the liquid matrix from leaking from the atomizing assembly 4 after the liquid storage member 214 of the second liquid storage chamber 211 retains too much liquid matrix.

[0105] In one embodiment of the present application, the aperture or diameter of the liquid guide hole 51 is 0.5 mm-1.5 mm. In one embodiment of the present application, the shape of the liquid guide hole 51 is a circular, elongated or other shaped opening, and the aperture or diameter of the liquid guide hole 51 is 0.5 mm-1.5 mm, so that the liquid guide hole 51 has a capillary effect. When the aerosol generating device 10 is inhaled by the user, the air pressure in the second liquid storage chamber 211 decreases, and the air pressure in the first liquid storage chamber 111 remains unchanged, so that the liquid matrix in the first liquid storage chamber 111 enters the second liquid storage chamber 211 through the liquid guide column 5; when the aerosol generating device 10 is not in a working state, the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 211 is balanced, and the liquid guide hole 51 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is ​​kept in the liquid guide hole 51, which prevents the liquid matrix from continuously entering the second liquid storage chamber 211 when the aerosol generating device 10 is not working, thereby causing the liquid matrix to leak through the atomizing assembly 4. In one embodiment of the present application, the aperture or diameter of the liquid guiding hole 51 may be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, or 15 mm.

[0106] In one embodiment of the present application, the liquid guiding column 5 is disposed on the liquid output member 13 , and the liquid guiding column 5 extends outward away from the first liquid storage chamber 111 . The first bracket 212 defines a liquid flow channel 14 , and the liquid flow channel 14 allows the liquid guiding column 5 to pass through.

The liquid guiding column 5 is provided on the first support 212 and extends outwardly away from the second liquid storage chamber 211.

[0110] In one embodiment of the present application, a spacing between the outer sidewall of the liquid guiding column 5 and the inner sidewall of the liquid flow channel 14 is maintained between 0.1 mm and 1.0 mm. At this time, there is also a capillary action between the outer sidewall of the liquid guiding column 5 and the inner sidewall of the liquid flow channel 14. When the aerosol generating device 10 is being suctioned by a user, the air pressure in the second liquid storage chamber 211 decreases, and the air pressure in the first liquid storage chamber 111 remains unchanged, such that the liquid matrix in the first liquid storage chamber 111 enters the second liquid storage chamber 211 through the liquid guiding column 5; when the aerosol generating device 10 is not in a working state, the air pressures in the first liquid storage chamber 111 and the second liquid storage chamber 211 are kept in balance, and there is a certain capillary action between the outer sidewall of the liquid guiding column 5 and the inner sidewall of the liquid flow channel 14 on the liquid matrix therein, and the liquid matrix is held between the outer sidewall of the liquid guiding column 5 and the inner sidewall of the liquid flow channel 14, avoiding the continuous entry of the liquid matrix into the second liquid storage chamber 211 when the aerosol generating device 10 is not working, thereby preventing the liquid matrix from leaking through the atomizing assembly 4. In one embodiment of the present application, the distance between the outer sidewall of the liquid guiding column 5 and the inner sidewall of the liquid flow channel 14 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm.
