[0040] The liquid reservoir 10 provided by the present application includes a child lock assembly 4. The child lock assembly 4 includes a base 41, a detachable portion 42, and a stress weakening portion 43. The stress weakening portion 43 can be broken under the action of an external force, so that the base 41 and the detachable portion 42 are separated. Before the liquid reservoir 10 is installed on the device main body 20, the child lock assembly 4 seals the first seal 3 within the first housing 1 to prevent the first seal 3 from being opened by children.

[0041] In an embodiment of the present application, the stress weakening portion 43 refers to a structure that is easily broken under the action of an external force.

[0042] In an embodiment of the present application, the stress weakening portion 43 may include a material that is easily broken after being stressed. For example, the material of the stress weakening portion 43 is a brittle material relative to the base 41 and the detachable portion 42.

[0043] In an embodiment of the present application, the base 41, the detachable portion 42, and the stress weakening portion 43 are made of the same material. The thickness of the stress weakening portion 43 is smaller than the thickness of the base 41 or the detachable portion 42. The stress weakening portion 43 can be broken under the action of an external force.

[0044] In an embodiment of the present application, the stress weakening portion 43 is a virtual broken line. That is, the stress weakening portion 43 includes a plurality of connecting portions 431 located between the base 41 and the detachable portion 42. The connecting portions 431, the base 41, and the detachable portion 42 jointly enclose a connecting groove 432 that can cooperate with the first housing 1. In an embodiment of the present application, the stress weakening portion 43 includes a plurality of connecting portions 431 and a plurality of connecting grooves 432.

The first housing 1 and the child lock assembly 4 are connected through the interference fit between the first buckle 12 and the connection groove 432. When the user detaches the detachable portion 42 from the base 41, the connecting portion 431 of the stress-weakened portion 43 breaks, and the snap connection between the first buckle 12 and the connection groove 432 disappears, separating the first housing 1 and the child lock assembly 4.

[0048] In an embodiment of the present application, the first housing 1 includes a first buckle 12. The detachable portion 42 can be provided with a first snap groove. The first housing 1 and the child lock assembly 4 are connected through the first buckle 12 and the first snap groove. When the user detaches the detachable portion 42 from the base 41, the connecting portion 431 of the stress-weakened portion 43 breaks, separating the base 41 and the first housing 1, and the detachable portion 42 remains on the first housing 1.

[0049] In an embodiment of the present application, the first housing 1 includes a guiding portion 13, and the child lock assembly 4 includes a guiding groove 45. The child lock assembly 4 is installed on the first housing 1 through the cooperation of the guiding portion 13 and the guiding groove 45.

[0051] In an embodiment of the present application, the detachable portion 42 can be in interference fit with the first housing 1, making the fit between the detachable portion 42 and the first housing 1 tighter before the stress-weakened portion 43 breaks. In an embodiment of the present application, the base 41 can be in interference fit with the first housing 1, making the fit between the base 41 and the first housing 1 tighter before the stress-weakened portion 43 breaks.

[0052] In one embodiment of the present application, the outer surface of the base 41 is provided with rough textures, so that when the user removes the detachable part 42, it is convenient for the user to fix the base 41 and apply external force to cause relative displacement with the detachable part 42, thereby removing the detachable part 42 from the base 41; on the other hand, it is convenient for the user to separate the base 41 from the first shell 1.

[0053] In one embodiment of the present application, the first housing 1 includes a mouthpiece 14 and an air tube 15. The mouthpiece 14 is connected to the first housing 1 for the user to hold in their mouth, and the air tube 15 is connected to the mouthpiece 14 for providing aerosol to the user.

The aperture or diameter of the liquid guiding hole 22 is 0.5 mm - 1.5 mm. The liquid guiding hole 22 has a capillary action. When the aerosol generating device 100 is sucked by the user, the air pressure in the second liquid storage cavity decreases, and the air pressure in the first liquid storage cavity 11 remains unchanged, so that the liquid matrix in the first liquid storage cavity 11 enters the second liquid storage cavity through the liquid guiding column 22. When the aerosol generating device 100 is not in the working state, the air pressures in the first liquid storage cavity 11 and the second liquid storage cavity are balanced. The liquid guiding hole 22 has a certain capillary action on the liquid matrix therein, and the liquid matrix is held in the liquid guiding hole 22, avoiding the continuous entry of the liquid matrix into the second liquid storage cavity when the aerosol generating device 100 is not working, so that the liquid matrix leaks through the atomization assembly. In one embodiment of the present application, the aperture or diameter of the liquid guiding hole 22 can be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm.

[0060] In one embodiment of the present application, the first seal 3 has at least one groove 31.

[0061] In one embodiment of the present application, the bracket 2 includes two liquid guiding columns 21. Correspondingly, the first seal 3 has two grooves 31, and the two liquid guiding columns 21 are respectively inserted into the two grooves 31.

[0062] In one embodiment of the present application, the bracket 2 includes a second buckle 24, and the first housing 1 includes a second clamping groove 16. The bracket 2 and the first housing 1 are fixedly connected through the second buckle 24 and the second clamping groove 16.

[0063] In one embodiment of the present application, the first seal 3 further includes an insertion groove 32. The air pipe 15 passes through the insertion hole 23 and then is inserted into the insertion groove 32. The first seal 3 also seals the air pipe 15 to prevent foreign objects from entering the air pipe 15.

[0064] In one embodiment of the present application, the liquid reservoir 10 further includes a second seal 5. The second seal 5 is arranged between the bracket 2 and the air pipe 15 to prevent the liquid matrix from leaking between the bracket 2 and the air pipe 15.

[0065] In one embodiment of the present application, the second seal 5 includes a first through hole 51, and the first liquid storage cavity 11 and the liquid guide hole 22 are communicated through the first through hole 51. In one embodiment of the present application, the second seal 5 includes a second through hole 52, and the air pipe 15 passes through the second through hole 52 and the insertion hole 23 and is inserted into the insertion groove 32.

[0066] In one embodiment of the present application, the first seal 3 includes a top surface 34, a bottom surface 35 and a side surface 36. The top surface 34 faces the liquid guide column 21, the bottom surface 35 faces the base 41, and the side surface 36 is located between the top surface 34 and the bottom surface 35.
