[0064] One embodiment of this application provides an aerosol generating device 10, as shown in Figures 1-3, comprising: a reservoir 1 and a device body 2. The reservoir 1 includes a first housing 11, within which a first reservoir chamber 111 for storing a liquid matrix and an outlet 121 for discharging the liquid matrix from the first reservoir chamber 111 are defined. The device body 2 includes a second housing 221 and an atomizer 21 disposed within the second housing 221, within which a second reservoir chamber 211 for storing the liquid matrix is ​​defined. The reservoir 1 also includes a liquid output member 13 disposed adjacent to the outlet, which is rotatable relative to the first housing 11 between a first position and a second position. When the liquid output member 13 is in the first position, the outlet 121 is opened, thereby connecting the first reservoir chamber 111 and the second reservoir chamber 211. When the liquid output member 13 is in the second position, the outlet 121 is blocked, thereby preventing the first reservoir chamber 111 from replenishing the second reservoir chamber 211 with the liquid matrix. The liquid reservoir 1 can be operatively connected to the atomizer 21 of the device body 2 from a separated state. After the liquid reservoir 1 is connected to the atomizer 21, the atomizer 21 can drive the liquid output component 13 to rotate. The liquid output component 13 remains connected to the atomizer 21 and cannot be separated in both the first and second positions.

[0065] The aerosol generating device 10 provided in this application has a first housing 11 and a liquid output component 13 that can rotate relative to each other. The first housing 11 and the liquid output component 13 can open or close the liquid outlet 121 by rotating relative to each other, so that the user can open and close the liquid outlet 121 according to the usage situation during the use of the aerosol generating device 10, thereby avoiding liquid matrix leakage.

[0066] One embodiment of this application provides a liquid reservoir 1, as shown in Figures 4-5 and 7. The liquid reservoir 1 includes a first housing 11 and a liquid output member 13. The first housing 11 defines a first liquid storage chamber 111 for storing a liquid matrix and a liquid outlet 121 for discharging the liquid matrix. The liquid output member 13 is disposed adjacent to the liquid outlet 121 and is rotatable relative to the first housing 11 between a first position and a second position. When the liquid output member 13 is in the first position, the liquid outlet 121 is opened, thereby connecting the first liquid storage chamber 111 and the second liquid storage chamber 211. When the liquid output member 13 is in the second position, the liquid outlet 121 is blocked, thereby preventing the first liquid storage chamber 111 from replenishing the second liquid storage chamber 211 with liquid matrix. The first housing 11 has a sleeve portion surrounding the liquid output member 13. The sleeve portion is provided with an arcuate groove 113 having a predetermined arc angle in the circumferential direction. The arcuate groove 113 is used to retain a portion of the atomizer 21 and provide a rotation path.

[0067] In one embodiment of this application, the first seal 31 is located between the first housing 11 and the liquid output component 13, preventing the liquid matrix in the first liquid storage chamber 111 from leaking between the first housing 11 and the liquid output component 13, thus maintaining good sealing even during relative rotation of the first housing 11 and the liquid output component 13. In one embodiment of this application, the liquid output component 13 defines a first receiving cavity 131, and the liquid reservoir 1 includes the first seal 31, which is disposed in the first receiving cavity 131. In one embodiment of this application, referring to FIG11, the first seal 31 defines a first through hole 311. When the first housing 11 is in a first position relative to the liquid output component 13, the first through hole 311 provides liquid connectivity between the first liquid storage chamber 111 and the second liquid storage chamber 211, allowing the liquid matrix in the first liquid storage chamber 111 to enter the second liquid storage chamber 211.

[0068] In one embodiment of this application, as shown in FIG4, the liquid reservoir 1 further includes a suction nozzle assembly 15 and an air tube 16. The suction nozzle assembly 15 is connected to the first housing 11 for a user to hold and draw in aerosol. The air tube 16 is connected to the suction nozzle assembly and located inside the first housing 11. In one embodiment of this application, the first housing 11, the suction nozzle assembly 15, and the air tube 16 are detachably connected. In another embodiment of this application, the first housing 11, the suction nozzle assembly 15, and the air tube 16 are detachably connected, and one end of the first housing 11 is an open end and the other end is a closed end, with the suction nozzle assembly 15 and the air tube 16 located at the open end.

In another embodiment of this application, when the first housing 11 is in the first position relative to the liquid output component 13, the liquid outlet 121 and the first through hole 311 of the first sealing component 31 at least partially overlap to ensure that the liquid matrix in the first liquid storage chamber 111 can enter the second liquid storage chamber 211. In another embodiment of this application, the first housing 11 is provided with a first insertion hole 126, one end of the air tube 16 is connected to the suction nozzle assembly 15, and the other end of the air tube 16 is inserted into the first insertion hole 126.

[0070] In one embodiment of this application, the first sealing member 31 is rotatable with the liquid output member 13 and is provided with a rib 312 in the direction facing the liquid outlet 121. The rib 312 defines a limiting groove for the liquid outlet 121 on the rotation path. During the rotation of the first housing 11 relative to the liquid output member 13, the liquid outlet 121 moves through the limiting groove formed by the rib 312, so that the liquid matrix in the first liquid storage chamber 111 will not leak during the relative rotation of the first housing 11 and the liquid output member 13. In one embodiment of this application, the rib 312 includes an annular first rib 3121, and a first through hole 311 is located inside the first rib 3121. When the first housing 11 is in a first position relative to the liquid output member 13, the projection of the liquid outlet 121 on the first sealing member 31 is within the range of the first rib 3121, so that when the liquid outlet 121 is opened, the liquid matrix in the first liquid storage chamber 111 will not leak. In one embodiment of this application, the rib 312 includes an annular second rib 3122, and the first through hole 311 avoids the second rib 3122. When the first housing 11 is in the second position relative to the liquid output member 13, the second rib 3122 closes the liquid outlet 121.

In addition, the second through groove 323 also communicates with a first through groove 2126, so that the first through groove 2126 can be connected to atmospheric pressure.

[0086] One embodiment of this application provides a main unit 22, as shown in Figures 23-24, including: a second housing 221, a battery assembly 222 disposed in the second housing 221, and a second magnetic element 223, wherein the battery assembly 222 is capable of providing electrical energy. In one embodiment of this application, the atomizer 21 and the main unit 22 are detachably connected via a first magnetic element 213 and a second magnetic element 223, allowing the user to replace one of the atomizer 21 and the main unit 22 as needed. In one embodiment of this application, the main unit 22 further includes a receiving cavity 224, within which the atomizer 21 is removably housed by the magnetic attraction of the first magnetic element 213 and the second magnetic element 223. In one embodiment of this application, a portion of the liquid reservoir 1 can be housed within the receiving cavity 224 and can rotate relative to the main unit 22.

[0087] In one embodiment of this application, the main unit 22 further includes a limiting portion 225 protruding from the receiving cavity 224. The limiting portion 225 is at least partially inserted into the atomizer 21 to prevent the atomizer 21 from rotating relative to the main unit 21. The first housing 11 can be provided for user operation to rotate relative to the atomizer 21. The limiting portion 225 is at least partially inserted into the atomizer 21 to prevent the atomizer 21 from rotating, thereby providing locking of the atomizer 21 to the liquid output member 13.

[0088] In one embodiment of this application, the first housing 11 of the liquid reservoir 1 includes a protrusion 114, and the second housing 221 of the main unit 22 includes a longitudinal guide groove 2211 and a circumferential guide groove 2212. The longitudinal guide groove 2211 provides a path for the protrusion 114 to be inserted, and the circumferential guide groove 2212 provides a path for the protrusion to rotate circumferentially. When the liquid reservoir 1 is inserted into the main unit 22, the protrusion 114 is first inserted along the longitudinal guide groove 2211, and then the first housing 11 and the second housing 221 are rotated relative to each other, so that the protrusion 114 can be assembled into place along the circumferential guide groove 2212.

[0089] In one embodiment of this application, when the liquid reservoir 1 is installed into the main body 2 of the device, or when the liquid reservoir 1 and the atomizer 21 are installed into the main unit, the first housing 11 and the base 12 of the liquid reservoir 1 are fixedly connected. The liquid output component 13 of the liquid reservoir 1 is positioned on the first bracket 212 by 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. The relative rotation of the first housing 11 and the second housing 221 can drive the base 12 and the liquid output component 13 to rotate relative to each other, thereby opening and closing the liquid outlet 121, thus making the first liquid storage chamber 111 and the second liquid storage chamber 211 connected or disconnected.

[0090] In one embodiment of this application, the aerosol generating device 10 further includes at least one liquid guiding column 5, which is hollow and has at least one liquid guiding hole 51, which is connected to the liquid outlet 121.

[0091] In one embodiment of this application, the number of liquid guiding columns 5 can be multiple, and the number of liquid guiding holes 51 corresponds to the number of liquid guiding columns 5. In one embodiment of this application, the number of liquid guiding columns 5 is two. When the liquid matrix in the liquid guiding hole 51 of one of the liquid guiding columns 5 enters the second liquid storage chamber 211 from the first liquid storage chamber 111, the air pressure in the first liquid storage chamber 111 decreases. At this time, the air in the second liquid storage chamber 211 can enter the first liquid storage chamber 211 through the liquid guiding hole 51 of the other liquid guiding column 5, thereby preventing the liquid matrix in the first liquid storage chamber 111 from being unable to enter the second liquid storage chamber 211 due to the decrease in air pressure.

[0092] In one embodiment of this application, a liquid guiding hole 51 is disposed on the side wall of the liquid guiding column 5. In another embodiment of this 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 smaller diameter of the liquid guiding hole 51 relative to the inner diameter of the hollow portion of the liquid guiding column 5 results in a slower outflow rate of the liquid matrix from the hollow portion of the liquid guiding column 5, thereby preventing leakage of the liquid matrix from the atomizing assembly 4 after excessive liquid matrix is ​​retained in the liquid storage component 214 of the second liquid storage chamber 211.

[0093] In one embodiment of this application, the aperture or diameter of the liquid guiding hole 51 is 0.5mm-1.5mm. In another embodiment of this application, the shape of the liquid guiding hole 51 is circular, elongated, or other shaped opening, and the aperture or diameter of the liquid guiding hole 51 is 0.5mm-1.5mm, so that the liquid guiding hole 51 has a capillary effect. When the aerosol generating device 10 is drawn in by the user, the air pressure in the second liquid storage chamber 211 decreases, while 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 guiding column 5. When the aerosol generating device 10 is not in working state, the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 211 remains balanced. The liquid guiding hole 51 has a certain capillary effect on the liquid matrix therein, and the liquid matrix is ​​retained in the liquid guiding hole 51, 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 component 4. In one embodiment of this application, the aperture or diameter of the liquid guiding hole 51 can be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, or 15 mm.

[0094] In one embodiment of this application, a liquid guide column 5 is disposed on a liquid output component 13. The liquid guide column 5 extends outward away from the first liquid storage cavity 111. The first bracket 212 defines a liquid flow channel 14 through which the liquid guide column 5 can pass.

[0095] In one embodiment of this application, a first support 212 is provided inside the second housing 221, a second liquid storage cavity 211 is defined within the first support 212, and a liquid guide column 5 is disposed on the first support 212 and extends outward away from the second liquid storage cavity 211. In another embodiment of this application, the liquid output component 13 is provided with a liquid flow channel 14 through which the liquid guide column 5 can pass.

[0096] In one embodiment of this application, the atomizer 21 includes a liquid storage element 214, which fills at least a portion of the space in the second liquid storage chamber 211, and the opening at one end of the liquid flow channel 14 is blocked by the liquid storage element 214.

[0097] In one embodiment of this application, the end of the liquid guiding column 5 is tapered, and the first sealing member 33 includes a sealing film, which is tapered, and the liquid guiding column 5 can puncture the sealing film.

[0098] In one embodiment of this application, the outer wall of the liquid guide column 5 and the inner wall of the liquid flow channel 14 are maintained at a distance between 0.1 mm and 1.0 mm. At this time, there is also a capillary effect between the outer wall of the liquid guide column 5 and the inner wall of the liquid flow channel 14. When the aerosol generating device 10 is drawn in by the user, the air pressure in the second liquid storage chamber 211 decreases, while 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 operation, the air pressure in the first liquid storage chamber 111 and the second liquid storage chamber 211 are balanced. The outer wall of the liquid guide column 5 and the inner wall of the liquid flow channel 14 have a certain capillary effect on the liquid matrix therein. The liquid matrix is ​​held between the outer wall of the liquid guide column 5 and the inner wall of the liquid flow channel 14, which avoids the liquid matrix continuously entering the second liquid storage chamber 211 when the aerosol generating device 10 is not in operation, thereby preventing the liquid matrix from leaking through the atomizing component 4. In one embodiment of this application, the distance between the outer wall of the liquid guiding column 5 and the inner wall of the liquid flow channel 14 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1.0 mm.

[0099] Referring to Figures 4 and 5, one embodiment of this application provides a liquid reservoir 1 as an independent accessory of an aerosol generating device. In its unused state, the liquid reservoir 1 can be independently packaged and stored. In its used state, the liquid reservoir 1 can be combined and connected with an atomizer 21. The liquid reservoir 1 includes a first housing 11 and a liquid output component 13. The first housing 11 defines a first storage chamber 111 for storing a liquid matrix and an outlet 121 for discharging the liquid matrix from the first storage chamber 111. The liquid output component 13 is disposed adjacent to the outlet 121 and is rotatable relative to the first housing 11 between a first position and a second position. When the liquid output component 13 is in the first position, the outlet 121 is open; when the liquid output component 13 is in the second position, the outlet 121 is blocked. The first housing 11 has a sleeve portion surrounding the liquid output component 13. The sleeve portion is provided with an arcuate groove 113 having a predetermined arc angle along the circumferential direction. The arcuate groove 113 is used to retain a portion of the atomizer 21 and provide a rotation path.
