[0002] In the prior art, a typical aerosol generation device is provided, which includes an independently existing liquid reservoir and a device body. The liquid reservoir is used to store a certain volume of liquid matrix, and a heating element for receiving the liquid matrix and evaporating the liquid matrix by heating is arranged in the device body. In some exemplary solutions, the liquid reservoir and the device body usually establish liquid conduction through a liquid guiding column with a liquid guiding hole. When the liquid reservoir is installed on the device body, the liquid guiding column of the liquid reservoir is inserted into the annular wall of the device body, and the annular wall of the device body abuts against the liquid storage member of the capillary material. During the suction process by the user, when the liquid matrix in the liquid reservoir is consumed and the air pressure becomes lower, the air in the device body must pass through the gap between the liquid guiding column and the annular wall, or pass through the liquid matrix held in the liquid storage member to enter the liquid reservoir. However, when the liquid matrix held in the liquid storage member is in a relatively saturated state, it is difficult for air to pass through the liquid storage member and enter the liquid reservoir, thereby preventing the liquid matrix in the liquid reservoir from being replenished to the liquid storage member in the device body through the above-mentioned liquid guiding column.

[0047] The present application provides an aerosol generating device 10, comprising: a liquid reservoir 1, including a first housing 11, the first housing 11 defining a first liquid storage chamber 111 for storing a liquid matrix; a device body 2, including a second housing 21, a first bracket 22 and a liquid storage member 23, the first bracket 22 being disposed within the second housing 21, the first bracket 22 defining a second liquid storage chamber 221 for storing a liquid matrix, the liquid storage member 23 being filled in at least a part of the space of the second liquid storage chamber 221 for receiving and holding the liquid matrix from within the first liquid storage chamber 111; the liquid reservoir 1 includes at least one liquid guiding column 12 extending outward from the first liquid storage chamber 111, the liquid guiding column 12 being hollow and having at least one liquid guiding hole 121 formed therein, the first bracket 22 includes at least one annular wall 222, an accommodating chamber 2221 is defined within the annular wall 222, at least a part of the liquid guiding column 12 extends into the accommodating chamber 2221 such that the liquid matrix in the first liquid storage chamber 111 is allowed to enter the second liquid storage chamber 221 through the accommodating chamber 2221, the liquid storage member 23 abuts against the end of the annular wall 222 to block the accommodating chamber 2221, and the annular wall 222 has a gas guiding channel 2222 that avoids being blocked by the liquid storage member 23, and the gas guiding channel 2222 provides a path for air to enter the accommodating chamber 2221.

[0048] In one embodiment of the present application, the annular wall 222 of the device body 2 of the aerosol generating device 10 has a gas guiding channel 2222, such that air in the second liquid storage chamber 221 of the device body 2 can enter the liquid reservoir 1 through the gas guiding channel 2222, avoiding the problem that air in the device body 2 must pass through the liquid matrix held between the liquid guiding column 12 and the annular wall 222 or the liquid storage member 23 to enter the liquid reservoir 1, and enabling the liquid matrix of the aerosol generating device 10 to enter the second liquid storage chamber from the first liquid storage chamber at a relatively fast speed.

[0049] In an embodiment of the present application, the liquid reservoir 1 includes a nozzle assembly 14 and a trachea 15. The nozzle assembly 14 is connected to the first housing 11 for the user to hold in the mouth. The trachea 15 is connected to the nozzle assembly 14 and is disposed within the first housing 11 for guiding the aerosol into the nozzle assembly 14. In an embodiment of the present application, the first housing 11, the nozzle assembly 14, and the trachea 15 are integrally formed. One end of the first housing 11 is a closed end, to which the integrally formed nozzle assembly 14 is connected. The other end of the first housing 11 is an open end. The first liquid reservoir 1 includes a second bracket 13. The second bracket 13 is disposed at the open end of the first housing 11. The liquid guiding column 12 is disposed on the second bracket 13. The liquid reservoir 1 with this structure can be filled with the liquid matrix from the open end and then the second bracket 13 can be installed. In an embodiment of the present application, the liquid reservoir 1 includes a second seal 16. The second seal 16 is located between the first housing 11 and the second bracket 13 for preventing the liquid matrix in the first liquid storage cavity 11 from leaking between the first housing 11 and the second bracket 13.

[0050] In an embodiment of the present application, one end of the first housing 11 is a closed end, to which the liquid guiding column 12 is connected. One end of the first housing 11 is an open end, to which the detachable nozzle assembly 14 and trachea 15 are connected. The liquid reservoir 1 with this structure can be filled with the liquid matrix from the open end and then the nozzle assembly 14 can be installed.

[0051] In an embodiment of the present application, at least a part of the annular wall 2222 protrudes towards the second liquid storage cavity 221. The annular wall 2222 and the liquid storage member 23 jointly define a first gas cavity 231. The first gas cavity 231 communicates with the receiving cavity 2221 through the air guiding channel 2222, so that the air in the first gas cavity 231 can enter the receiving cavity 2221 through the air guiding channel 2222 and then enter the first liquid storage cavity 111 from the receiving cavity 2221, enabling the liquid matrix in the first liquid storage cavity 111 to quickly enter the second liquid storage cavity 221.

[0052] In an embodiment of the present application, the first housing 11 includes a first buckle 112. The second housing 21 has a first slot 211. The first housing 11 and the second housing 21 are connected through the first buckle 112 and the first slot 211. In an embodiment of the present application, the first housing 11 further includes a first protrusion 113. The second housing 21 has a guiding groove 212. The first housing 11 and the second housing 21 are installed through the first protrusion 113 and the guiding groove 212. In an embodiment of the present application, the first housing 11 has a second slot 114. The second bracket 13 includes a second buckle 131. The first housing 11 and the second bracket 13 are connected through the second slot 114 and the second buckle 131.

[0053] In an embodiment of the present application, the number of liquid guiding columns 12 can be multiple, and the number of liquid guiding holes 121 corresponds to the number of liquid guiding columns 12. In an embodiment of the present application, the number of liquid guiding columns 12 is two. When the liquid matrix in the liquid guiding hole 121 of one of the liquid guiding columns 12 enters the second liquid storage cavity 221 from the first liquid storage cavity 111, the air pressure in the first liquid storage cavity 111 decreases. At this time, the air in the second liquid storage cavity 221 can enter the first liquid storage cavity 111 through the liquid guiding hole 121 of the other liquid guiding column 12, thereby preventing the liquid matrix in the first liquid storage cavity 111 from being unable to enter the second liquid storage cavity 211 due to the decrease in air pressure.

[0054] In an embodiment of the present application, the number of annular walls 222 corresponds to the number of liquid guiding columns 12. In an embodiment of the present application, the number of liquid guiding columns 12 is two, and the number of annular walls 222 is two. In an embodiment of the present application, the first bracket 22 includes a first annular wall 2223 and a second annular wall 2224. An air guiding channel 2222 is provided in one of the two annular walls 222 of the first annular wall 222, such that one liquid guiding column 12 of the aerosol generating device 10 and the second annular wall 2224 form a liquid outlet channel, and the other liquid guiding column 12 and the first annular wall 222 with the air guiding channel 2222 form an air inlet channel. Thus, the liquid outlet channel and the air inlet channel are relatively independent and will not cause relative interference between them, ensuring the smooth outflow of the liquid matrix in the liquid storage device. In an embodiment of the present application, both of the two annular walls 222 have an air guiding channel 2222, making it easier for the air of the aerosol generating device 10 to enter the first liquid storage cavity 111 from the first gas cavity 231 through the receiving cavity 2221, and making it easier for the liquid matrix to quickly enter the second liquid storage cavity 221 from the first liquid storage cavity 111.

[0055] In an embodiment of the present application, the liquid guiding hole 121 is provided on the side wall of the liquid guiding column 12. In an embodiment of the present application, the aperture of the liquid guiding hole 121 is smaller than the inner diameter of the hollow part of the liquid guiding column 12. The aperture of the liquid guiding hole 121 is relatively small with respect to the inner diameter of the hollow part of the liquid guiding column 12, such that the outflow speed of the liquid matrix from the hollow part of the liquid guiding column 12 is slower, thereby avoiding the leakage of the liquid matrix from the atomizing component 24 after too much liquid matrix is retained in the liquid storage member 23 of the second liquid storage cavity 221.

[0056] In an embodiment of the present application, the aperture diameter or diameter of the liquid guiding hole 121 is 0.5 mm - 1.5 mm. In an embodiment of the present application, the shape of the liquid guiding hole 121 is a circular opening, a strip-shaped opening or an opening of other shapes, and the aperture diameter or diameter of the liquid guiding hole 121 is 0.5 mm - 1.5 mm, so that the liquid guiding hole 121 has a capillary action. When the aerosol generating device 10 is sucked by the user, the air pressure in the second liquid storage cavity 221 decreases, and the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid matrix in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guiding column 12; when the aerosol generating device 10 is not in a working state, the air pressures in the first liquid storage cavity 111 and the second liquid storage cavity 211 are balanced, and the liquid guiding hole 121 has a certain capillary action on the liquid matrix therein, and the liquid matrix is held in the liquid guiding hole 121, avoiding that when the aerosol generating device 10 is not working, the liquid matrix continuously enters the second liquid storage cavity 221, so that the liquid matrix leaks through the atomization assembly 24. In an embodiment of the present application, the aperture diameter or diameter of the liquid guiding hole 121 can be 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm.

[0057] In an embodiment of the present application, the outer side wall of the liquid guiding column 12 and the inner side wall of the annular wall 222 maintain a spacing between 0.1 mm and 1.0 mm. At this time, there is also a capillary action between the outer side wall of the liquid guiding column 12 and the inner side wall of the annular wall 222. When the aerosol generating device 10 is sucked by the user, the air pressure in the second liquid storage cavity 221 decreases, and the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid matrix in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guiding column 12; when the aerosol generating device 10 is not in a working state, the air pressures in the first liquid storage cavity 111 and the second liquid storage cavity 221 are balanced, and the outer side wall of the liquid guiding column 12 and the inner side wall of the annular wall 222 have a certain capillary action on the liquid matrix therein, and the liquid matrix is held between the outer side wall of the liquid guiding column 12 and the inner side wall of the annular wall 222, avoiding that when the aerosol generating device 10 is not working, the liquid matrix continuously enters the second liquid storage cavity 221, so that the liquid matrix leaks through the atomization assembly 24. In an embodiment of the present application, the distance between the outer side wall of the liquid guiding column 12 and the inner side wall of the annular wall 222 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm.

[0058] In an embodiment of the present application, the liquid guiding column 12 abuts against the liquid storage member 23.

[0059] In one embodiment of the present application, the distance between the liquid guiding column 12 and the liquid storage member 23 is 0.1 mm - 1.0 mm. At this time, there is also a capillary action between the liquid guiding column 12 and the liquid storage member 23. When the aerosol generating device 10 is sucked by the user, the air pressure in the second liquid storage cavity 221 decreases, and the air pressure in the first liquid storage cavity 111 remains unchanged, so that the liquid matrix in the first liquid storage cavity 111 enters the second liquid storage cavity 221 through the liquid guiding column 12; when the aerosol generating device 10 is not in a working state, the air pressures in the first liquid storage cavity 111 and the second liquid storage cavity 221 are balanced, and there is a certain capillary action on the liquid matrix therein between the liquid guiding column 12 and the liquid storage member 23, and the liquid matrix is held between the liquid guiding column 12 and the liquid storage member 23, avoiding the continuous entry of the liquid matrix into the second liquid storage cavity 221 when the aerosol generating device 10 is not working, so that the liquid matrix leaks through the atomizing assembly 24. In one embodiment of the present application, the distance between the liquid guiding column 12 and the liquid storage member 23 can be 0.1 mm, 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm.

[0060] In one embodiment of the present application, the device body 2 includes a liquid storage member 23 made of a capillary core material, and all or part of the liquid matrix in the second liquid storage cavity 221 is received or held by the liquid storage member 214, so that when the aerosol generating device 10 or the device body 2 is in transportation or static state, the liquid matrix in the second liquid storage cavity 221 is not easily leaked through the atomizing assembly 24; and a better taste can be obtained at the initial stage of suction when the user uses the aerosol generating device 10. In one embodiment of the present application, the liquid storage member 23 can be made of an elastic organic porous material, and the liquid storage member 23 can have a hardness or flexibility between that of a normal flexible plant cotton / non-woven fabric (Shore hardness less than 20A) and that of a rigid porous ceramic / microporous metal (Shore hardness greater than 80A), so that the structure is stable and has extremely low expansion after absorbing and infiltrating the liquid matrix, and has a certain hardness so that it can be easily fixed and held. In one embodiment of the present application, the liquid storage member 23 can be hard rayon.

[0061] In one embodiment of the present application, one end of the annular wall 2221 abuts against the liquid storage member 23, and the other end is connected to the first bracket 22, so that the annular wall 222 encloses a receiving cavity 2221 for receiving the liquid matrix. The annular wall 222 has a gas guiding channel 2222, so that the gas cavities in the receiving cavity 2221 and the second liquid storage cavity 221 are communicated, so that the air in the second liquid storage cavity 221 can pass through the gas guiding channel 2222 of the annular wall 222 and then enter the first liquid storage cavity 111 through the receiving cavity 2221, ensuring the air pressure balance between the first liquid storage cavity 111 and the second liquid storage cavity 221, so that the liquid matrix of the aerosol generating device 10 can enter the second liquid storage cavity from the first liquid storage cavity at a faster speed.

[0062] In one embodiment of the present application, the air guiding channel 2222 includes a notch, and the notch is located on the side of the annular wall facing the second liquid storage cavity 221.

[0063] In one embodiment of the present application, the air guiding channel 2222 is a groove provided on the annular wall 22, so that the air in the second liquid storage cavity 221 can enter the receiving cavity 2221.

[0064] In one embodiment of the present application, the air guiding channel 2222 is a groove, a slit or a notch provided on the annular wall 22, so that the receiving cavity 2221 and the trachea 15 maintain gas communication.

[0065] In one embodiment of the present application, the size of the air guiding channel 2222 in at least one direction is 0.1 mm - 1.0 mm, so that the air guiding channel 2222 has a capillary action. When the user inhales the aerosol generating device 10 and the liquid matrix is consumed, the air in the second liquid storage cavity 221 will enter the first liquid storage cavity 11; when the user does not inhale the aerosol generating device 10 and the liquid matrix is not consumed, the air guiding channel 2222 can hold a certain amount of liquid matrix, avoiding the liquid matrix from entering the second liquid storage cavity 221 from the first liquid storage cavity 111, and avoiding the excessive liquid matrix in the second liquid storage cavity 221 from leaking from the atomizing assembly 24. In one embodiment of the present application, the minimum width size of the air guiding channel 2222 is 0.1 mm - 1.0 mm. In one embodiment of the present application, the minimum pore size of the air guiding channel 2222 is 0.1 mm - 1.0 mm.

[0066] In one embodiment of the present application, the inner side wall of the first bracket 22 has a rib 223, and the liquid storage member 23 abuts against the rib 223, so that an air passage that is vertically communicated is formed between the first bracket 22 and the liquid storage member 23, and the gas cavities on the upper and lower sides of the liquid storage member 23 in the second liquid storage cavity 221 are communicated, so that the liquid matrix in the liquid storage member 23 is more evenly distributed.

[0067] In one embodiment of the present application, the device main body 2 includes an atomizing assembly 24, and the atomizing assembly 24 is disposed in the second housing 22 and adjacent to the second liquid storage cavity 221, and is used for atomizing the liquid matrix held in the liquid storage member 23 to generate aerosol.

In an embodiment of the present application, the inner side wall of the first bracket 22 near the mounting hole 224 has a first air passage 225, and the first air passage 225 communicates the first gas chamber 231 with the external air. When the user inhales the aerosol generating device 10, the liquid matrix in the second liquid storage chamber 221 is consumed and the air pressure becomes smaller. On the one hand, the liquid matrix in the first liquid storage chamber 111 enters the second liquid storage chamber 221. On the other hand, the external air enters the second liquid storage chamber 221 through the first air passage 225 to maintain the air pressure balance in the second liquid storage chamber 221.

[0069] In an embodiment of the present application, the device body 2 further includes a first seal 26. The first bracket 22 includes a liquid injection hole 226 and a receiving cavity 227. The first seal 26 is disposed in the receiving cavity 227 and seals the liquid injection hole 226. In an embodiment of the present application, the second bracket 22 has a liquid injection hole 226, and the liquid matrix in the second liquid storage chamber 221 can be injected through the liquid injection hole 226 and retained in the liquid storage member 23. In an embodiment of the present application, the first seal 26 includes a plug body 261, and the plug body 261 is disposed in the liquid injection hole 226 and seals it.

[0070] In an embodiment of the present application, the first seal 26 has a first through hole 262 and a second through hole 263. The first through hole 262 communicates with the mounting hole 224. The trachea 15 and the support tube 25 are sleeved on the first through hole 262. The second through hole 263 communicates with the annular wall 222, so that the liquid matrix in the first liquid storage chamber 111 can enter the second liquid storage chamber 221.

[0071] In an embodiment of the present application, the device body 2 further includes a battery assembly 27, and the battery assembly 27 supplies electric energy to the atomization assembly 24.
