The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this utility model belongs. The terms used in this specification and in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more of the relevant listed items.

[0035] See also Figure 1-Figure 3 , an embodiment of the present application provides a liquid reservoir 100. The liquid reservoir 100 includes a first shell 1, a bracket 2, a first sealing member 3 and a child lock member 4. Specifically, the first shell 1 is provided with a first clamping structure 11. The bracket 2 is arranged in the first shell 1, and the bracket 2 and the first shell 1 jointly define a first liquid storage cavity 5 for storing a liquid matrix. The bracket 2 is provided with a liquid conducting channel 21, and the liquid conducting channel 21 is used for allowing the liquid matrix to flow out. The first sealing member 3 seals the liquid conducting channel 21. The child lock member 4 is provided with a second clamping structure 41, and the child lock member 4 and the first shell 1 are detachably connected through the second clamping structure 41 and the first clamping structure 11. Wherein, under the action of external force, the second clamping structure 41 is separated from the first clamping structure 11, so that the child lock member 4 is removed from the first shell 1 and the first sealing member 3 is exposed. By adding a child lock component 4 to the liquid reservoir 100, and the child lock component 4 and the first shell 1 are detachably connected to the first snap-fit ​​structure 11 through the second snap-fit ​​structure 41, it is difficult for children to remove the child lock component 4, preventing the first sealing component 3 from being easily opened by children, thereby preventing the risk of liquid matrix leakage and accidental ingestion by children.

[0036] In some embodiments, one of the first locking structure 11 and the second locking structure 41 includes a locking slot, and the other includes a buckle.

[0037] In some embodiments, see Figure 4 The second clamping structure 41 is provided with a pressing portion 411 and a clamping portion 412 , one end of the pressing portion 411 is fixed to the clamping portion 412 , and the clamping portion 412 is clamped to the first clamping structure 11 , so that the second clamping structure 41 is clamped to the first clamping structure 11 .

[0038] As an example, the first snap-fit ​​structure 11 includes a slot, and the second snap-fit ​​structure 41 includes a buckle. In other words, the buckle is located in the snap-fit ​​portion 412 and is snap-fitted to the slot. The other end of the pressing portion 411 is fixed to the child lock member 4, and the end of the snap-fit ​​portion 412 away from the pressing portion 411 is a free end. Under the action of an external force, the pressing portion 411 is pressed to deform, driving the snap-fit ​​portion 412 to move, so that the buckle disengages from the slot, thereby removing the child lock member 4 from the first housing 1. The second snap-fit ​​structure 41 is provided with a pressing portion 411 and a snap-fit ​​portion 412, so that the first housing 1 has a support function and its rigidity is maintained. As another example, the first snap-fit ​​structure 11 includes a buckle, and the second snap-fit ​​structure 41 includes a slot. In other words, the slot is located in the snap-fit ​​portion 412 and is snap-fitted to the buckle.

[0039] In some embodiments, the number of the first clamping structures 11 and the number of the second clamping structures 41 are both two, the two first clamping structures 11 are disposed opposite to each other, and the two second clamping structures 41 are disposed opposite to each other.

[0040] In some embodiments, the child lock component 4 is provided with a pressing groove 42, and the pressing portion 411 is accommodated in the pressing groove 42. There is a first gap between the two sides of the pressing portion 411 and the side walls of the pressing groove 42, so that the pressing portion 411 has movement space, and thus the pressing portion 411 can move relative to the pressing groove 42.

[0041] In some embodiments, the surface of the pressing portion 411 is provided with thick lines 4111 to prevent the pressing portion 411 from sliding when the user presses it when removing the child lock component 4, thereby facilitating the user to separate the child lock component 4 from the first shell 1.

[0042] In some embodiments, the child lock component 4 is provided with a reinforcing plate 43. One end of the reinforcing plate 43 is fixed to the side wall of the pressing groove 42. The reinforcing plate 43 is provided with a first receiving groove 431. The first receiving groove 431 is connected to the pressing groove 42 and receives the engaging portion 412. A second gap is provided between the engaging portion 412 and the side wall of the first receiving groove 431, allowing the engaging portion 412 to move relative to the first receiving groove 431. The reinforcing plate 43 increases the stability of the engagement between the buckle and the slot, preventing the buckle from loosening or falling off easily due to external vibration or impact.

[0043] In some embodiments, see Figure 5 The first housing 1 is provided with a guide groove 12, and the first engaging structure 11 is provided on the side wall of the guide groove 12. The guide groove 12 accommodates at least a portion of the reinforcing plate 43. When the child lock member 4 is installed on the first housing 1, the reinforcing plate 43 slides along the guide groove 12, causing the second engaging structure 41 to slide along the guide groove 12, thereby aligning and engaging the second engaging structure 41 with the first engaging structure 11, making it easier for the user to install the child lock member 4.

[0044] In some embodiments, see Figure 4 The child lock member 4 is provided with a support column 44, which is hollow. The support column 44 supports the first sealing member 3 to support the first sealing member 3 and prevent the first sealing member 3 from loosening or falling off due to external vibration or impact, causing the liquid guide channel 21 to be exposed and leaking the liquid matrix.

[0045] In some embodiments, see Figure 7 The bracket 2 is provided with a liquid guiding column 22 , which is hollow and has at least one liquid guiding hole 221 . The hollow liquid guiding column 22 is connected to the liquid guiding hole 221 to form a liquid guiding channel 21 .

[0046] In some embodiments, there are two liquid-conducting holes 221 , which are disposed opposite to each other. Obviously, in some embodiments, there are at least three liquid-conducting holes 221 , which are disposed around the liquid-conducting column 22 .

[0047] In some embodiments, there are two liquid-conducting columns 22 , and the two liquid-conducting columns 22 are arranged opposite to each other.

[0048] In some embodiments, the liquid guiding hole 221 is disposed on a side wall of the liquid guiding column 22 .

[0049] In some embodiments, the diameter of the liquid-conducting hole 221 is smaller than the inner diameter of the hollow portion of the liquid-conducting column 22. The smaller diameter of the liquid-conducting hole 221 relative to the inner diameter of the hollow portion of the liquid-conducting column 22 slows down the flow of the liquid matrix out of the hollow portion of the liquid-conducting column 22, thereby preventing leakage of the liquid matrix.

[0050] In some embodiments, the aperture or diameter of the liquid guide hole 221 is 0.5 mm to 1.5 mm. In some embodiments, the liquid guide hole 221 is circular, elongated, or has other shapes. The aperture or diameter of the liquid guide hole 221 is 0.5 mm to 1.5 mm, and the liquid guide hole 221 has a capillary effect.

[0051] In some embodiments, the aperture or diameter of the liquid guide hole 221 may be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, or 1.5 mm.

[0052] In some embodiments, see Figure 3 The first sealing member 3 is provided with a second receiving groove 31, which receives the liquid-conducting column 22, and the first sealing member 3 seals the liquid-conducting hole 221. It should be noted that the number of the second receiving grooves 31 corresponds to the number of the liquid-conducting columns 22, that is, the number of the second receiving grooves 31 is the same as the number of the liquid-conducting columns 22.

[0053] In some embodiments, see Figure 3 and Figure 7 The first housing 1 is provided with a suction nozzle 13 and an airflow tube 14, and the bracket 2 is provided with a socket 23. The suction nozzle 13 is connected to the airflow tube 14, and the end of the airflow tube 14 away from the suction nozzle 13 is plugged into the socket 23.

[0054] In some embodiments, see Figure 2 The first shell 1 is provided with a third clamping structure 15 , and the bracket 2 is provided with a fourth clamping structure 24 . The bracket 2 and the first shell 1 are clamped and fixed with the third clamping structure 15 via the fourth clamping structure 24 .

[0055] In some embodiments, see Figure 5 and Figure 6 One of the third clamping structure 15 and the fourth clamping structure 24 is a clamping slot, and the other is a clamping block, which is clamped in the clamping slot. As an example, the third clamping structure 15 is a clamping slot, and the fourth clamping structure 24 is a clamping block.

[0056] In some embodiments, see Figure 6 The bracket 2 is provided with a guide block 25, which is at least partially received in the guide groove 12. When the bracket 2 is mounted on the first housing 1, the guide block 25 slides along the guide groove 12, causing the fourth engaging structure 24 to slide along the guide groove 12, thereby aligning and engaging the fourth engaging structure 24 with the third engaging structure 15, making it easier for the user to install the bracket 2.

[0057] In some embodiments, the number of each of the third clamping structure 15, the fourth clamping structure 24, and the guide block 25 is two. The two third clamping structures 15 are disposed opposite to each other. The two fourth clamping structures 24 are disposed opposite to each other. The two guide blocks 25 are disposed opposite to each other.

[0058] In some embodiments, see Figure 2 and Figure 3 The liquid reservoir 100 further includes a second seal 6 , which is disposed between the bracket 2 and the first shell 1 . The second seal 6 is used to prevent the liquid matrix from leaking from between the bracket 2 and the first shell 1 , and from leaking from between the bracket 2 and the airflow tube 14 .

[0059] In some embodiments, see Figure 8 The second sealing member 6 is provided with a first through hole 61, which connects the first liquid storage cavity 5 and the liquid guiding channel 21. It should be noted that the number of the first through holes 61 is the same as the number of the liquid guiding columns 22.

[0060] In some embodiments, the second sealing member 6 is provided with a plug-in column 62, which is plugged into the socket 23. The plug-in column 62 is provided with a second through hole 621, and the second through hole 621 is for the airflow tube 14 to be plugged in. The plug-in column 62 is clamped by the side wall of the socket 23 and the airflow tube 14 to play a sealing role, thereby preventing the liquid matrix from leaking from between the airflow tube 14 and the bracket 2.

[0061] The present invention also provides an embodiment of an aerosol generating device, which includes a device body and the above-mentioned liquid reservoir 100. The liquid reservoir 100 can be connected to the device body after the child lock 4 and the first sealing member 3 are removed. The device body is provided with a second liquid storage chamber, and the first liquid storage chamber 5 provides a liquid matrix to the second liquid storage chamber. For the structure and function of the liquid reservoir 100, please refer to the above-mentioned embodiment and will not be described in detail here.

[0062] When the aerosol generating device is inhaled by the user, the air pressure in the second liquid storage chamber decreases, while the air pressure in the first liquid storage chamber 5 remains unchanged, so that the liquid matrix in the first liquid storage chamber 5 enters the second liquid storage chamber through the liquid guide channel 21; when the aerosol generating device is not in an operating state, the air pressure in the first liquid storage chamber 5 and the second liquid storage chamber remains balanced, and the liquid guide hole 221 has a certain capillary effect on the liquid matrix therein, so that the liquid matrix is ​​retained in the liquid guide hole 221, thereby preventing the liquid matrix from continuously entering the second liquid storage chamber when the aerosol generating device is not operating, thereby preventing the liquid matrix from leaking through the device body.

[0063] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. These embodiments do not serve as additional limitations on the content of the present invention. The purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of the present invention; further, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present invention.
