[0048] One embodiment of this application provides a liquid matrix replenishment container 10, comprising: a first housing 1, a first support 2, a first seal 3, and a cover 4. The first support 2 and the first housing 1 together define a first liquid storage cavity 11 for storing liquid matrix. The first support 2 also defines a liquid passage 21, which communicates with the first liquid storage cavity 11 and provides a path for the liquid matrix to flow out of the first liquid storage cavity 11. The first seal 3 is disposed within the liquid passage 21 to prevent the liquid matrix from flowing out of the liquid passage 21, and the first seal 3 has a receiving cavity 33. The cover 4 is disposed on the first support 2 and covers the opening of the liquid passage 21. The cover 4 includes a first cover 41 and a second cover 42 connected to each other. The first cover 41 is removably connected to the first support 2, and at least a portion of the second cover 42 extends into the receiving cavity 33 of the first seal 3, thereby radially abutting the first seal 3 against the inner wall of the liquid passage 21.

[0049] The cover 4 of the liquid matrix replenishment container 10 of this application is connected to the first support 2 and blocks the opening of the liquid passage 21, which avoids the problem of liquid matrix leakage caused by children opening the first seal 3. Furthermore, the second cover 42 of the cover 4 abuts against the first seal 3, so that the cover 4 and the first seal 3 will not loosen, thereby avoiding the problem of leakage.

[0050] In one embodiment of this application, the first housing 1 and the first support 2 of the liquid matrix replenishment container 10 jointly define a first liquid storage cavity 11 for storing liquid matrix and together constitute the outer surface of the liquid matrix replenishment container 10. The liquid matrix replenishment container 10 is used to provide liquid matrix to the device body 20 of the aerosol generating device 100. In one embodiment of this application, a second sealing member is further provided between the first housing 1 and the first support 2 to prevent leakage of liquid matrix in the liquid storage cavity 11 defined by the first housing 1 and the first support 2.

[0051] In one embodiment of this application, the liquid matrix may comprise a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The liquid matrix may comprise water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include menthol, peppermint, spearmint oil, various fruit flavoring components, etc., but are not limited to these. Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical and electronic aerosol atomization.

[0052] In one embodiment of this application, the first support 2 includes a sidewall 25 and a bottom wall 26 adjacent to the sidewall 25. A liquid passage 21 is located on the sidewall 25, and the bottom wall 26 defines an injection hole 27. The liquid matrix in the liquid matrix replenishment container 10 is injected into the first liquid storage chamber 11 through the injection hole 27, and the liquid matrix in the first liquid storage chamber 11 can flow out through the liquid passage 21 into the device body 20. In one embodiment of this application, the liquid matrix replenishment container 10 further includes a silicone stopper 6, which is disposed on the injection hole 27 and seals the injection hole 27.

[0053] In one embodiment of this application, the projection of the injection hole 27 onto the side wall 25 at least partially coincides with the liquid passage 21, allowing almost all of the liquid matrix in the first liquid storage chamber 11 to flow into the liquid passage 21. In another embodiment of this application, the bottom wall 26 is inclined along the direction of the injection hole 27 toward the liquid passage 21, and the projection of the injection hole 27 onto the side wall 25 at least partially coincides with the liquid passage 21. The inclined bottom wall 26 allows the liquid matrix in the first liquid storage chamber 11 to flow along the bottom wall 26 toward the liquid passage 21.

[0054] In one embodiment of this application, the first cover 41 includes a first snap-fit ​​portion 411, and the second cover 42 includes a second snap-fit ​​portion 421. The first cover 41 and the second cover 42 are connected by the first snap-fit ​​portion 411 and the second snap-fit ​​portion 421. In one embodiment of this application, one of the first snap-fit ​​portion 411 and the second snap-fit ​​portion 421 is a buckle, and the other of the first snap-fit ​​portion 411 and the second snap-fit ​​portion 421 is a slot. In one embodiment of this application, the slot may be defined between two protrusions. In one embodiment of this application, after the first cover 41 and the second cover 42 are assembled together, they are installed to the first bracket 2, such that the second cover 42 abuts against the first sealing member 3. In one embodiment of this application, both the first cover 41 and the second cover 42 are injection-molded plastic parts.

[0055] In one embodiment of this application, the first cover 41 includes a rib 415, and the second cover 42 includes a guide groove 422. The rib 415 of the first cover 41 is installed to the second cover 42 along the guide groove 422 of the second cover 42.

[0056] In one embodiment of this application, the first cover 41 is configured to be rotatable by a user from a locked position to an unlocked position. When the first cover 41 is in the locked position, it is restricted from detaching along the first support 2. When the first cover 41 is in the unlocked position, it can be removed from the first support 2 to expose the opening of the liquid passage 21. In one embodiment of this application, when the first cover 41 is in the locked position, it is restricted from detaching along the first support 2, and the second cover abuts against the first seal 3 to prevent leakage of the liquid matrix in the liquid passage 21. In one embodiment of this application, when the first cover 41 is in the unlocked position, it can be removed from the first support 2 to expose the first seal 3, allowing the user to open the first seal 3 to provide a path for the liquid matrix in the first reservoir 11 to flow out.

[0057] In one embodiment of this application, the user needs to go through two steps to open the cover 3: first, rotate the cover 3 from the locked position to the unlocked position, and then remove the cover 3, thereby preventing the cover 3 from being opened by children.

[0058] In one embodiment of this application, the first bracket 2 includes a first protrusion 22 disposed on the outer surface of the first bracket 2, and the first cover 41 includes a limiting groove 412 and a guide groove 413 disposed on its inner surface and communicating with each other. The limiting groove 412 defines the path for the first protrusion 22 to rotate from the locked position to the unlocked position, and the guide groove 413 defines the path for the first protrusion 22 to be removed from the first bracket.

[0059] In one embodiment of this application, the first support 2 includes a main body 23 and a liquid passage 24. The liquid passage 24 extends outward from the main body 23 and defines a liquid passage 21. A first protrusion 22 is located on the outer surface of the liquid passage 24.

[0060] In one embodiment of this application, the cross-section of the liquid-passing part 24 and the cross-section of the first cover 41 are generally annular. The liquid-passing part 24 and the first cover 41 can rotate relative to each other, thereby allowing the first cover 41 to switch between a locked position and an unlocked position.

[0061] In one embodiment of this application, the first protrusion 22 extends along the circumferential direction of the liquid-passing portion 24. In one embodiment of this application, the first protrusion 22 is elongated. In one embodiment of this application, the limiting groove 412 of the first cover 41 extends along the circumferential direction of the first cover 41, and the guide groove 413 of the first cover 41 extends along the axial direction of the first cover 41. The first cover 41 and the liquid-passing portion 24 rotate relative to each other, causing the first cover 41 to switch from the locked position to the unlocked position. Then, the first cover 41 can be removed by pulling it out along the axial direction of the first cover 41. At this time, the second cover 42 also disengages from the first seal 3 along with the first cover 41.

[0062] In one embodiment of this application, the first protrusion 22 is provided with a groove 221, and the first cover 41 is provided with a second protrusion 414. When the first cover 41 is in the locked position, the second protrusion 414 is located in the groove 221. The groove 221 on the first protrusion 22 and the second protrusion 414 on the first cover allow the user to feel that the cover 4 is properly installed when it is mounted on the first bracket 2, thanks to the engagement of the groove 221 and the second protrusion 414. In one embodiment of this application, when the user removes the first cover 41, a preset external force is required to break the engagement of the groove 221 and the second protrusion 414. In one embodiment of this application, the preset force prevents a child from rotating the first cover 41 from the locked position to the unlocked position, but allows an adult to rotate the first cover 41 from the locked position to the unlocked position. In one embodiment of this application, the preset value is 10N-50N, for example, the preset value can be 10N, 15N, 20N, 23N, 28N, 30N, 35N, 38N, 40N, 45N or 50N.

[0063] In one embodiment of this application, the second protrusion 414 extends along the axial direction of the first cover 41. In another embodiment of this application, the second protrusion 414 is elongated.

[0064] In one embodiment of this application, the liquid matrix replenishment container 10 includes a sealing mask 5 disposed on the side of the liquid passage 21 away from the first liquid storage chamber 11. The sealing mask 5 has a through hole 53 through which at least a portion of the second cover 42 passes, and the inner diameter of the through hole 53 is smaller than the outer diameter of the first seal 3. The liquid matrix replenishment container 10 is fitted with the sealing mask 5 before the cover 4 is installed. When the cover 4 is removed from the first support 2, the sealing mask 5 prevents the first seal from being removed along with the cover 4.

[0065] In one embodiment of this application, a sealing mask 5 is disposed over the liquid-passing portion 24. The sealing mask 5 is provided with a third snap-fit ​​portion 51, and the liquid-passing portion 24 is provided with a fourth snap-fit ​​portion 241. The sealing mask 5 and the liquid-passing portion 24 are connected through the third snap-fit ​​portion 51 and the fourth snap-fit ​​portion 241. In another embodiment of this application, the sealing mask 51 further includes a clearance portion 52, through which a first protrusion 22 on the liquid-passing portion 24 is exposed to the sealing mask 5.

[0066] In one embodiment of this application, the first sealing element 3 includes a sealing body 31 and a sealing liquid portion 32. A receiving cavity 33 is located within the sealing body 31. The sealing body 31 is disposed within the liquid passage 21, and the sealing liquid portion 32 is disposed within the sealing body 31 to close the receiving cavity 33. In one embodiment of this application, the sealing body 31 has a raised rib on the side facing the first cover 41, thereby sealing the sealing body 31 and the first cover 41. In one embodiment of this application, the sealing body 31 has a raised rib on the side facing the second cover 42, thereby sealing the sealing body 31 and the second cover 42.

[0067] In one embodiment of this application, the sealing portion 32 is a silicone film. When the liquid matrix replenishment container 10 is installed onto the device body 20, the sealing portion 32 is punctured, allowing the liquid matrix in the liquid passage 21 to flow into the device body 20. In one embodiment of this application, the thickness of the sealing portion 32 is 0.15mm-0.3mm, so that the sealing portion 32 can be punctured by the device body 20. In one embodiment of this application, the thickness of the sealing portion 32 is 0.15mm, 0.18mm, 0.2mm, 0.23mm, 0.25mm, 0.28mm, or 0.3mm.

[0068] In one embodiment of this application, the sealing part 32 is a one-way valve, allowing the liquid matrix in the liquid passage 21 to flow out of the liquid passage 21, while the liquid matrix in the device body 20 can flow into the liquid passage. In another embodiment of this application, the sealing part 32 protrudes towards the first liquid storage chamber 11, such that the sealing part 32 is punctured along the direction from the device body 20 toward the liquid matrix replenishment container 10. When the liquid matrix replenishment container 10 is removed from the device body 20, the sealing part 32 protruding towards the first liquid storage chamber 11 closes again, preventing the liquid matrix in the liquid passage 21 from flowing out.

[0069] One embodiment of this application provides an aerosol generating device, including a device body 20 and the aforementioned liquid matrix replenishment container 10. The liquid matrix replenishment container 10 can be assembled to the device body 20 after the cover 4 is removed, and is used to provide liquid matrix to the device body 20.

[0070] In one embodiment of this application, the device body 20 includes a cartridge assembly 201, a liquid matrix replenishment container 10, and a battery rod 202. After the liquid matrix replenishment container 10 and the cartridge assembly 201 are assembled together, they can be installed onto the battery rod 202.

[0071] In one embodiment of this application, the battery rod 202 includes a second housing 2021, which defines a mounting cavity 20211 in which the liquid matrix replenishment container 10 and the cartridge assembly 201 are mounted.

[0072] In one embodiment of this application, the cartridge assembly 201 includes a second support 2011, which includes a support body 20111 and a connecting portion 20112 connected to each other. When the liquid matrix replenishment container 10 is installed on the cartridge assembly 201, the connecting portion 20112 punctures the first seal 3 of the liquid matrix replenishment container 10, so that the liquid matrix in the liquid passage 21 can flow to the cartridge assembly 201.

[0073] In one embodiment of this application, the second support 2011 defines a second liquid storage chamber 20113, and the second liquid storage chamber 20113 is provided with a liquid storage component 2012 for absorbing and holding liquid matrix. The liquid matrix in the liquid matrix replenishment container 10 can enter the second liquid storage chamber 20113 through the liquid passage 21.

[0074] In one embodiment of this application, the liquid storage component 2012 can be made of an elastic organic porous material. The liquid storage component 2012 can have a hardness or flexibility between that of ordinary flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and rigid porous ceramic / microporous metal (Shore hardness greater than 80A). Therefore, the structure is stable and has extremely low expansion after absorbing and wetting the liquid matrix, and also has a certain hardness so that it can be easily fixed and maintained.

[0075] In one embodiment of this application, the liquid reservoir 2012 may be rigid synthetic cotton.

[0076] In one embodiment of this application, the cartridge assembly 201 further includes an atomizing assembly 2013 disposed in the second liquid storage chamber 20113. The atomizing assembly 2013 can absorb and atomize the liquid matrix to generate an aerosol for the user to inhale.

[0077] In one embodiment of this application, the atomizing assembly 2013 may include a liquid-absorbing element and a heating element, with the heating element disposed on the liquid-absorbing element. The liquid-absorbing element may be a porous body for guiding the liquid matrix into the atomization range of the heating element. The heating element is used to heat the atomized aerosol matrix, thereby generating an aerosol. The porous body may be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body may also be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0078] In one embodiment of this application, the atomizing component 2013 may include an ultrasonic element capable of high-frequency vibration under ultrasonic drive. The atomizing component 2013 utilizes ultrasonic vibration to atomize a liquid matrix into an aerosol. Of course, the atomizing component 2013 may also include other elements capable of atomizing a liquid matrix into an aerosol.

[0079] In one embodiment of this application, the battery rod 202 further includes a battery assembly 2022 that provides electrical power to the atomizing assembly 2013. The DC supply voltage provided by the battery assembly 2022 is in the range of about 2.5V to about 9.0V, and the DC current provided by the battery assembly 2022 is in the range of about 2.5A to about 20A. Typically, the battery assembly 2022 is a rechargeable battery. Alternatively, the battery assembly 2022 may be another form of charge storage device, such as a capacitor. The battery assembly 2022 may require recharging and may have a capacity that allows for storing sufficient energy for one or more aspirations; for example, the battery assembly 2022 may have sufficient capacity to allow for continuous aerosol generation over a predetermined period of time. In another example, the battery assembly 2022 may have sufficient capacity to allow for the initiation of a predetermined number of aerosol-generating articles.

[0080] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification.
