[0044] The present application provides an embodiment of a liquid reservoir 10, comprising a housing 1, a bracket 2, and a cover 3. The housing 1 defines a liquid storage chamber 11 for storing a liquid matrix. The bracket 2 is disposed within the housing 1 and has a liquid guide hole 21, which provides a path for the liquid matrix in the liquid storage chamber 11 to flow out. The cover 3 is connected to one end of the housing 1 and blocks the liquid guide hole 21, preventing the liquid guide hole 21 from being opened. The cover 3 is configured to be rotatable by a user from a locked position to an unlocked position. When the cover 3 is in the locked position, the cover 3 is restricted from longitudinally disengaging from the housing 1. When the cover 3 is in the unlocked position, the cover 3 can be removed from the housing 1 longitudinally to expose the liquid guide hole 21. A resistance providing mechanism 7 is at least partially disposed on the housing 1 and is configured to provide resistance during the rotation of the cover 3 from the locked position to the unlocked position.

[0045] The liquid reservoir 10 provided in the present application includes a cover body 3 connected to the shell 1 and covering the liquid guide hole 21. The cover body 3 needs to be rotated by the user from a locked position to an unlocked position before it can be removed and the liquid guide hole 21 can be exposed, thereby avoiding the problem of children opening the liquid guide hole 21 and causing the liquid matrix to leak. In addition, the cover body 3 is prevented from rotating from the unlocked position to the locked position. The cover body 3 can only be removed when it is in the unlocked position, making the removal of the cover body 3 more convenient.

[0046] In one embodiment of the present application, the shell 1 includes a first protrusion 12, which is arranged on the outer surface 13 of the shell 1, and the cover body 3 includes a limiting groove 31 and a guide groove 32 arranged on its inner surface and connected to each other. The limiting groove 31 defines the path for the first protrusion 12 to rotate from the locked position to the unlocked position, and the guide groove 32 extends roughly along the longitudinal direction of the cover body 3 to define the path for the first protrusion 12 to be removed from the shell.

[0047] In one embodiment of the present application, the limiting groove 31 extends along the circumferential direction of the liquid reservoir 10. In the process of the cover body 3 moving from the locked position to the unlocked position by rotation, the cover body 3 and the shell 1 only have a relative position change in the circumferential direction of the liquid reservoir 10.

[0048] In one embodiment of the present application, the extension direction of the limiting groove 31 has components in both the circumferential direction and the circumferential direction of the liquid reservoir 10. In the process of the cover body 3 moving from the locked position to the unlocked position by rotation, not only a relative change in position occurs in the circumferential direction of the liquid reservoir 10, but also a relative change in position occurs in the circumferential direction of the liquid reservoir 10.

[0049] In one embodiment of the present application, the extension direction of the guide groove 32 is along the axial direction of the liquid reservoir 10 , and the cover body 3 is removed from the housing 1 along the axial direction of the liquid reservoir 10 .

[0050] In one embodiment of the present application, when the cover 3 is in the unlocked position, the first protrusion 12 is located in the guide groove 32, so that the first protrusion 12 can move along the guide groove 32, thereby allowing the cover 3 to be removed from the housing 1. When the cover 3 is in the locked position, at least a portion of the first protrusion 12 is located in the limiting groove 31. At this time, the first protrusion 12 cannot move along the guide groove 32, so that the cover 3 cannot be removed from the housing 1.

[0051] In one embodiment of the present application, when the cover 3 is in the unlocked position, the first protrusion 12 is located at the intersection of the limiting groove 31 and the guide groove 32, so that the first protrusion 12 can move along the guide groove 32 to remove the cover 3 from the housing 1. When the cover 3 is in the locked position, the first protrusion 12 is located on the side of the limiting groove 31 away from the guide groove 32. At this time, the first protrusion 12 cannot move along the guide groove 32, and thus the cover 3 cannot be removed from the housing 1.

[0052] In one embodiment of the present application, the first protrusion 12 extends in the circumferential direction of the outer surface of the shell 1, and the size of the first protrusion 12 in the circumferential direction of the liquid reservoir 10 is larger than the size of the first protrusion 12 in the axial direction of the liquid reservoir 10, so that when the cover body 3 is in the locked position, the first protrusion 12 produces greater interference in the axial direction and is difficult to disengage from the limiting groove 31, but is easy to rotate in the circumferential direction of the liquid reservoir 10.

[0053] In one embodiment of the present application, the first protrusion 12 has a first side surface 121 facing the cover body 3, and the first side surface 121 is inclined from the intersection of the first side surface 121 and the outer surface 13 of the shell 1 toward a direction away from the cover body 3, so as to facilitate the first protrusion 12 to be installed in the limit groove along the longitudinal direction of the cover body 3.

[0054] In one embodiment of the present application, the diameter of the first protrusion 12 of the shell 1 is larger than the diameter of the inner surface of the cover body 3, and the cover body 3 can be a material with a certain elasticity, such as polycarbonate (PC), so that during the process of installing the first protrusion 12 to the limiting groove 31, the cover body 3 can produce a certain elastic deformation, and after the first protrusion 12 is installed to the limiting groove 31, the cover body 3 returns to its original state.

[0055] In one embodiment of the present application, the diameter of the first protrusion 12 of the shell 1 is smaller than the diameter of the limiting groove 31 of the cover body 3, so that after the first protrusion 12 can be installed in the limiting groove 31, the cover body 3 is in a locked position and cannot be removed from the shell 1.

[0056] In one embodiment of the present application, the first protrusion 12 has a second side surface 122 away from the cover body 3, and the second side surface 122 is inclined toward a direction away from the cover body 3 from the intersection of the second side surface 122 and the outer surface 13 of the shell 1, or the second side surface 122 is basically perpendicular to the longitudinal direction of the outer surface of the shell 1 to prevent the first protrusion 12 from sliding out of the limiting groove 31.

[0057] In one embodiment of the present application, the first protrusion 12 is in an elongated strip shape.

[0058] In one embodiment of the present application, the resistance providing mechanism 7 includes a second protrusion 14 arranged on the outer surface of the shell 1 and a rib 33 arranged on the inner surface of the cover body 3. The second protrusion 14 can interfere with the rib 33, thereby providing resistance during the process of rotating the cover body 3 from the locked position to the unlocked position.

[0059] In one embodiment of the present application, the cover 3 includes a first groove 34 and a second groove 35 separated by a rib 33 . When the cover 3 rotates from the locked position to the unlocked position, the second protrusion 14 rotates from the first groove 34 to the second groove 35 .

[0060] In one embodiment of the present application, the second protrusion 14 extends in the axial direction of the housing 1. The size of the second protrusion 14 in the axial direction of the liquid reservoir 10 is greater than the size of the second protrusion 14 in the circumferential direction of the liquid reservoir 10, so that when the cover 3 is rotated from the locked position to the unlocked position, the second protrusion 14 is interfered with by the rib 33 in the circumferential direction. The force required to rotate the cover 3 from the locked position to the unlocked position needs to be greater than a preset value. The preset value prevents children from rotating the cover 3 from the locked position to the unlocked position, but adults can rotate the cover 3 from the locked position to the unlocked position. In one embodiment of the present application, the preset value is 10N-50N, for example, the preset value can be 10N, 15N, 20N, 23N, 28N, 30N, 35N, 38N, 40N, 45N, 50N.

[0061] In one embodiment of the present application, the rib 33 extends along the axial direction of the liquid reservoir 10. The dimension of the rib 33 in the axial direction of the liquid reservoir 10 is greater than the dimension of the rib 33 in the circumferential direction of the liquid reservoir 10, so that when the cover 3 is rotated from the locked position to the unlocked position, the rib 33 is interfered with by the second protrusion 14 in the circumferential direction. The force applied during the rotation of the cover 3 from the locked position to the unlocked position needs to be greater than a preset value. The preset value prevents children from rotating the cover 3 from the locked position to the unlocked position, but adults can rotate the cover 3 from the locked position to the unlocked position.

[0062] In one embodiment of the present application, the rib 33 has a third side surface 331 facing the first groove 34, the first groove 34 has a first bottom surface 341, and the third side surface 331 is inclined from the intersection of the third side surface 331 and the first bottom surface 341 toward a direction away from the first groove 34, so that the second protrusion 14 passes over the rib 33 via the third side surface 331.

[0063] In one embodiment of the present application, the rib 33 has a fourth side surface 332 facing the second groove 35, the second groove 35 has a second bottom surface 351, the fourth side surface 332 is inclined from the intersection of the fourth side surface 332 and the second bottom surface 351 toward a direction away from the first groove 34, or the fourth side surface 332 is basically perpendicular to the second bottom surface 351 to prevent the cover body 3 from rotating back from the unlocked position to the locked position.

[0064] In one embodiment of the present application, the limiting groove 31 and the guide groove 32 are distributed counterclockwise along the circumference of the liquid reservoir 10. When the cover 3 rotates from the locked position to the unlocked position, the cover 3 rotates counterclockwise relative to the housing 1. Correspondingly, the first groove 34 and the second groove 35 are distributed counterclockwise along the circumference of the liquid reservoir 10.

[0065] In one embodiment of the present application, the number of the first protrusions 12 is two, and correspondingly, the number of the limiting grooves 31 and the number of the guide grooves 32 are also two. In one embodiment of the present application, the number of the second protrusions is two, and correspondingly, the number of the first grooves 34 and the number of the second grooves 35 are also two.

[0066] In one embodiment of the present application (not shown), the second protrusion 14 has a fifth side surface along the direction from the locked position to the unlocked position, and the fifth side surface is inclined from the intersection of the fifth side surface and the outer surface 13 of the housing 1 toward the unlocked position, so as to facilitate the rotation of the cover 3 from the locked position to the unlocked position. In one embodiment of the present application (not shown), the second protrusion 14 has a sixth side surface along the direction from the unlocked position to the locked position, and the sixth side surface is inclined from the intersection of the sixth side surface and the outer surface 13 of the housing 1 toward the locked position, or the sixth side surface extends from the intersection of the sixth side surface and the outer surface of the housing 1 in the radial direction of the liquid reservoir 10, so as to prevent the cover 3 from rotating from the unlocked position to the locked position.

[0067] In one embodiment of the present application, a bell mouth is provided on a side of the first groove 34 facing the housing 1 , so that the process of installing the second protrusion 14 in the first groove 34 is more convenient.

[0068] In one embodiment of the present application, the second protrusion 14 of the shell 1 is inserted into the bell mouth of the first groove 34 of the cover body 3, so that the cover body 3 is installed on the shell 1, and at the same time, the first protrusion 12 of the shell 1 interferes with the inner surface of the cover body 3, and the cover body 3 undergoes a certain deformation. After the first protrusion 12 is installed in the limiting groove 21, the cover body 3 recovers its deformation, and the first protrusion 12 is located in the limiting groove 31. Moreover, since the second side surface 122 of the first protrusion 12 is inclined from the intersection of the second side surface 122 and the outer surface 13 of the shell 1 toward a direction away from the cover body 3, or the second side surface 122 extends radially outward from the intersection of the second side surface 122 and the outer surface 13 of the shell 1 along the liquid reservoir 10, the first protrusion 12 cannot slide out of the limiting groove 31, and the cover body 3 is in a locked position.

[0069] In one embodiment of the present application, markings are provided on the second protrusion 14 of the housing 1 and the first groove 34 of the cover 3 to facilitate installation of the cover 3 on the housing 1. In one embodiment of the present application, a pair of arrows pointing opposite to each other are provided on the second protrusion 14 of the housing 1 and the first groove 34 of the cover 3 to facilitate installation of the cover.

[0070] In one embodiment of the present application, the outer surface of the cover 3 is provided with a rough structure to increase the friction when the user rotates the cover 3, making it easier for the user to rotate the cover 3. In one embodiment of the present application, the outer surface of the cover 3 is provided with vertical lines.

[0071] In one embodiment of the present application, the first protrusion 14 of the housing 1 rotates from the side of the limiting groove 31 away from the guide groove 32 to the intersection of the limiting groove 31 and the guide groove 32, and the cover 3 rotates from the locked position to the unlocked position. At this time, the second protrusion 14 moves from the first groove 34 across the rib 33 to the second groove. During the process of the second protrusion 14 moving from the first groove 34 to the second groove 35, a predetermined force must be overcome. The predetermined force is beyond the reach of an average child, thereby preventing children from opening the cover 3 and preventing leakage.

[0072] In one embodiment of the present application, when the cover 3 is in the unlocked position, the user can pull the cover 3 so that the first protrusion 12 passes through the guide groove 32, thereby removing the cover 3 from the shell 1. The user can open the liquid guide hole 21 to allow the liquid matrix in the liquid storage chamber 11 to flow out.

[0073] In one embodiment of the present application, when the cover 3 is in the unlocked position, the fourth side surface 332 is inclined from the intersection of the fourth side surface 332 and the second bottom surface 351 in a direction away from the first groove 34, or the fourth side surface 332 extends radially outward from the intersection of the fourth side surface 332 and the second bottom surface 351 in the liquid reservoir 10, so that the cover 3 cannot be rotated from the unlocked position to the locked position. As a result, the state between the cover 3 and the housing 1 can only be changed in the order of installation to locking, from locking to unlocking, and from unlocking to removal, making the installation and removal process of the cover 3 and the housing 1 more convenient and concise.

[0074] In one embodiment of the present application, the bracket 2 includes a hollow liquid-conducting column 22 extending outward from the liquid storage cavity 11 , and the liquid-conducting hole 21 is provided on a side wall of the liquid-conducting column 21 .

[0075] In one embodiment of the present application, the bracket 2 includes a buckle 23, and the housing 1 includes a slot 15, and the bracket 2 and the housing 1 are connected via the buckle 23 and the slot 15. In one embodiment of the present application, the slot 15 is located at one end of the second protrusion 14.

[0076] In one embodiment of the present application, the liquid reservoir 10 includes a seal 4 for sealing the liquid guide hole 21 . The seal 4 is disposed on the bracket 2 and covered by the cover 3 . The seal 4 includes an insertion hole 41 , and the liquid guide column 22 is inserted into the insertion hole 41 .

[0077] In one embodiment of the present application, the seal 4 includes a notch 42 , which allows a user's hand to act on the seal 4 to remove the seal 4 from the bracket 2 to expose the liquid guide hole 21 , thereby allowing the liquid matrix in the liquid reservoir 10 to flow out.

[0078] In one embodiment of the present application, a silicone film is provided on the liquid guide hole 21, which can prevent the liquid matrix in the liquid storage chamber 11 from leaking. When the cover body 3 is removed from the shell 1, the silicone film can be punctured by the user, so that the liquid matrix in the liquid storage chamber 11 can flow out of the liquid guide hole 21.

[0079] In one embodiment of the present application, the liquid reservoir 10 includes a mouthpiece 5 and an air tube 6. The mouthpiece is connected to the housing 1 for the user to hold in his mouth, and the air tube 6 is connected to the mouthpiece 5 for transporting the aerosol generated by the atomization assembly 20 to the mouthpiece 5.

[0080] In one embodiment of the present application, an aerosol generating device 100 is provided, comprising a battery assembly 30, an atomizer assembly 20 and the above-mentioned liquid reservoir 10. The atomizer assembly 20 is used to connect with the liquid reservoir 10 after removing the cover and atomize the liquid matrix. The battery assembly 30 is used to provide electrical energy to the atomizer assembly 20.

[0081] In one embodiment of the present application, liquid matrix can comprise the liquid that contains the tobacco material that contains volatile tobacco flavor component, can also be the liquid that comprises non-tobacco material.Liquid matrix can comprise water, medicinal liquid, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, peppermint, spearmint oil, various fruity fragrance components etc., but is not limited to this.

Vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and the vitamin E, but is not limited to this.Based on the different attributes of liquid matrix, aerosol matrix reservoir can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0082] In one embodiment of the present application, the atomizer assembly 20 includes a chamber for receiving and storing a liquid matrix. The atomizer assembly 20 also includes an atomizer core for atomizing the liquid matrix. The atomizer core is in fluid communication with the chamber, thereby enabling the atomizer core to transfer and atomize the liquid matrix in the chamber. After the atomizer assembly 20 is coupled to the liquid reservoir 10, the atomizer assembly 20 is connected to the liquid guide hole 21, allowing the liquid matrix in the liquid reservoir 10 to flow into the chamber of the aerosol generating device 100, thereby replenishing the chamber with the liquid matrix.

[0083] In one embodiment of the present application, the atomizer core may include a liquid wick and a heating element, with the heating element disposed on the liquid wick.
