Therefore, such terms should not be construed as limitations to the embodiments of the present application.

[0035] An embodiment of the present application provides a storage assembly 10, configured to store an aerosol-generating material in an aerosol-generating device. Referring to FIG. 1 to FIG. 4 and FIG. 6 to FIG. 9, the storage assembly 10 includes a storage member 12 and a blocking member 13.

[0036] The storage member 12 is provided with a storage cavity 10a for storing the aerosol-generating material and an exhaust channel 14a for discharging an aerosol.

[0037] The storage member 12 is made of a light-transmitting material to observe the aerosol-generating material in the storage cavity 10a from the outside of the storage member 12.

[0038] The light-transmitting material is the material with the light transmittance of not less than 50%.

[0039] In this way, during use of the aerosol-generating device, a user can observe a stock of the aerosol-generating material in the storage cavity 10a through the storage member 12, so that the user determines replenishment timing of the aerosol-generating material.

[0040] The exhaust channel 14a passes through the storage member 12, so that the aerosol can pass through the exhaust channel 14a to be inhaled by the user.

[0041] A column 14 is arranged in the storage cavity 10a, and the exhaust channel 14a is at least partially located in the column 14. It may be understood that, after the user stops inhaling the aerosol, a part of the aerosol cannot be discharged from the exhaust channel in time, and then is condensed on the inner wall of the exhaust channel 14a to form a condensate. Because the storage member 12 is made of the light-transmitting material, the user can observe the condensate on the inner wall of the exhaust channel 14a.

[0042] The blocking member 13 is arranged in the storage cavity 10a, where the column 14 passes through the blocking member 13. In other words, the blocking member 13 can block the line of sight of the user, to reduce a probability that the user directly observes the condensate on the inner wall of the exhaust channel 14a.

[0043] In the storage assembly 10 in this embodiment of the present application, the storage member 12 made of the light-transmitting material is arranged, so that the user can observe the stock of the aerosol-generating material in the storage cavity 10a, and the user can more accurately determine timing at which the aerosol-generating material is exhausted. The blocking member 13 is arranged, so that the probability that the user directly observes the condensate on the inner wall of the exhaust channel 14a is reduced, and the user's sense of view during the use can be improved.

[0044] It may be understood that, after the user observes, through the storage member, that the aerosol-generating material in the storage assembly 10 is exhausted, the user may select to replace the storage assembly 10 to replenish the aerosol-generating material in the aerosol-generating device; or the user may select to directly discard the aerosol-generating device, in other words, the aerosol-generating device is disposable.

[0045] A specific manner of replacing the storage assembly 10 is not limited.

[0046] For example, only the storage assembly 10 may be replaced, in other words, components such as an atomization core 11 and a power supply assembly 20 in the aerosol-generating device are fixedly connected to be reused, so that costs of replenishing the aerosol-generating material are reduced. For another example, the storage assembly 10 and the atomization core 11 jointly form an atomizer, and the atomizer is detachably configured, so that the aerosol-generating material is replenished by replacing the atomizer through overall disassembly and assembly. In this way, a new atomization core 11 is replaced, thereby improving efficiency of atomizing the aerosol after the replacement.

[0047] In an embodiment in which the atomizer can be replaced through overall disassembly and assembly, referring to FIG. 2, the storage member includes a shell 121 and a mounting base kit 122, where the shell 121 covers a side of the mounting base kit 122 to jointly enclose the storage cavity. The atomization core 11 includes an atomization region, where the atomization region can atomize the aerosol-generating material to form the aerosol through heating or the like. The atomization core 11 is arranged in an atomization cavity in the mounting base kit 122, and a plurality of channels are formed in the mounting base kit, where the channels are partially for conveying the aerosol-generating material to the atomization core 11, and are partially for discharging the aerosol out of the exhaust channel 14a.

[0048] A specific manner of forming the atomization region is not limited. For example, the atomization core 11 includes a substrate and a heating element, where the substrate is configured to come into contact with the aerosol-generating material and absorb the aerosol-generating material, and the heating element forms the atomization region to generate heat to atomize the aerosol-generating material in the substrate to form the aerosol.

[0049] It should be noted that, a specific material of the atomization core 11, a related structure and principle for forming the aerosol through atomization, a specific structure of a forming channel of the mounting base kit 122, and the like are disclosed in the related art, and are not described herein again.

[0050] It may be understood that, the light transmittance of the material of the blocking member 13 is less than that of the material of the storage member 12, or the material of the blocking member 13 is opaque, to block the line of sight of the user, thereby reducing the probability that the user directly observes the condensate on the inner wall of the exhaust channel 14a.

[0051] It may be understood that, the color of the outer surface of the blocking member 13 is different from the color of the aerosol-generating material, so that the user can determine the stock of the aerosol-generating material in the storage cavity 10a based on the blocking member 13 as a background reference.

[0052] It may be understood that, the blocking member 13 occupies a part of a volume in the storage cavity 10a.

[0053] In some embodiments, referring to FIG. 4, the blocking member 13 is provided with an accommodating cavity 13a and a communicating hole 13b. The blocking member 13 is provided with the communicating hole 13b, the accommodating cavity 13a is in communication with the storage cavity 10a through the communicating hole 13b, and the communicating hole 13b is for the aerosol-generating material to flow out of the accommodating cavity 13a.

[0054] To be specific, a part of the aerosol-generating material can be stored in the accommodating cavity 13a, and as the aerosol-generating material in the storage cavity 10a is consumed, the aerosol in the accommodating cavity 13a can flow into the storage cavity 10a through the communicating hole 13b for use.

[0055] In this way, the accommodating cavity 13a is arranged, so that the amount of the aerosol-generating material stored in the storage assembly 10 can be increased, thereby prolonging the service life of the storage assembly 10.

[0056] In some embodiments, the accommodating cavity 13a is located above the communicating hole 13b in a height direction of the column 14. The height direction is the direction of gravity during use of the aerosol-generating device.

[0057] In this way, during the use of the aerosol-generating device, the aerosol-generating material in the accommodating cavity 13a can directly flow into the communicating hole 13b under the action of gravity, so that a probability that the aerosol-generating material accumulated in the accommodating cavity 13a cannot be replenished into the storage cavity 10a is reduced.

[0058] The blocking member 13 is at least partially made of a light-transmitting material, so that the user can observe the stock of the aerosol-generating material in the accommodating cavity 13a.

[0059] In some embodiments, the side of the blocking member 13 close to the column 14 is made of a non-light-transmitting material, and the side of the blocking member 13 away from the column 14 is made of a light-transmitting material, so that the probability that the user observes the condensate in the exhaust channel 14a is reduced while the user can observe the aerosol-generating material in the accommodating cavity 13a.

[0060] In some embodiments, referring to FIG. 2 to FIG. 4, FIG. 7, and FIG. 9, the column 14 extends in a straight-line direction, so that the exhaust channel 14a can extend in the straight-line direction, thereby improving efficiency of discharging the aerosol; and the thickness of the wall of the column 14 can be reduced, thereby improving space utilization in the storage assembly 10.

[0061] In some embodiments, referring to FIG. 2 to FIG. 4, and FIG. 7, the two ends of the blocking member 13 in an extending direction of the column 14 abut against the inner wall of the storage cavity 10a.

[0062] In this way, the inner wall of the storage cavity 10a limits a position of the blocking member 13 in the extending direction of the column 14, so that the blocking member 13 remains fixed in the extending direction of the column 14, thereby reducing an adverse impact of an abnormal sound generated by movement of the blocking member 13 on user experience, and ensuring that the blocking member 13 always blocks the column 14.

[0063] It may be understood that, the two ends of the blocking member 13 in the extending direction of the column 14 may abut against only the storage member 12; or may abut against only the atomization core 11. Alternatively, one end of the blocking member 13 in the extending direction of the column 14 may abut against the storage member 12, and the other end of the blocking member 13 in the extending direction of the column 14 may abut against the atomization core 11.

[0064] In some embodiments, in FIG. 2 to FIG. 4, the outer side surface of the column 14 in an extending direction of the column 14 is tapered, the blocking member 13 is provided with a through mounting hole 13c, the inner wall of the mounting hole 13c is tapered in the extending direction of the column 14, and the inner wall of the mounting hole 13c can be attached to the outer side surface of the column 14 in the extending direction of the column 14.

[0065] To be specific, the cross-sectional area of the column 14 perpendicular to the extending direction of the column 14 gradually increases in the extending direction of the column 14, the cross-sectional area of the inner wall of the mounting hole 13c perpendicular to the extending direction of the column 14 gradually increases in the extending direction of the column 14, and the cross-sectional areas increase in the same direction. The outer side surface of the column 14 in the extending direction of the column 14 can abut against the inner wall of the mounting hole 13c in the extending direction of the column 14, thereby limiting a tendency of the blocking member 13 moving in a direction in which the cross-sectional area of the column 14 increases in the extending direction of the column 14.

[0066] In this way, the blocking member 13 can remain fixed in the extending direction of the column 14, thereby reducing an adverse impact of an abnormal sound generated by movement of the blocking member 13 on user experience, and ensuring that the blocking member 13 always blocks the column 14.

[0067] In some embodiments, the end of the blocking member 13 away from a direction in which the cross-sectional area of the blocking member 13 perpendicular to an extending direction of the column 14 increases in the extending direction of the column 14 abuts against the inner wall of the storage cavity 10a, so that the position of the blocking member 13 can remain fixed.

[0068] Specific shapes of the tapered shape of the outer side surface of the column 14 in the extending direction of the column 14 and the tapered shape of the inner wall of the mounting hole 13c in the extending direction of the column 14 are not limited, for example, a cone or a pyramid.

[0069] It may be understood that, the tapered shape of the outer side surface of the column 14 in the extending direction of the column 14 and the tapered shape of the inner wall of the mounting hole 13c in the extending direction of the column 14 are the same.

[0070] In some embodiments, referring to FIG. 2, FIG. 4, FIG. 7, and FIG. 9, the storage member further includes a supply channel 12a, the supply channel 12a is in communication with the storage cavity 10a, and the supply channel 12a is for the aerosol-generating material to flow out of the storage cavity 10a. In this way, the aerosol-generating material in the storage cavity 10a can be discharged from the storage assembly 10 through the supply channel 12a.

[0071] In some embodiments in which the communicating hole 13b is provided, referring to FIG. 4, the opening of the end of the communicating hole 13b away from the accommodating cavity 13a is located on the side of the blocking member 13 close to the inlet of the supply channel 12a, so that the aerosol-generating material in the accommodating cavity 13a can enter the supply channel 12a in a more timely manner.

[0072] In some embodiments in which the supply channel 12a is provided, referring to FIG. 2 and FIG. 4, the blocking member 13 is spaced apart from the inlet of the supply channel 12a.

[0073] In this way, a probability that the inlet of the supply channel 12a is blocked because the blocking member 13 comes into contact with the atomization core 11 can be avoided, thereby maintaining free flow between the storage cavity 10a and the supply channel 12a.

[0074] In some embodiments in which the supply channel 12a is provided, referring to FIG. 2 and FIG. 4, the column 14 extends in a first direction, and on a projection plane perpendicular to the first direction, the projection of the inlet of the supply channel 12a is located within the projection range of the blocking member 13.

[0075] In this way, the blocking member 13 can have a blocking effect on the inlet of the supply channel 12a, thereby improving the user's sense of view.

[0076] A specific manner in which the blocking member 13 is spaced apart from the inlet of the supply channel 12a is not limited.

[0077] For example, a plurality of support protrusions are arranged on the end surface of the end of the atomization core 11 close to the storage member 12 in the first direction, and the support protrusions extend in the first direction and abut against the blocking member 13. In other words, the blocking member 13 is spaced apart from the inlet of the supply channel 12a in the first direction.

[0078] In some embodiments in which the supply channel 12a is provided, on a projection plane perpendicular to the first direction, the projection of the inlet of the supply channel 12a is at least partially located on the outer side of the projection of the blocking member 13 away from the projection of the column 14. In other words, the blocking member 13 is spaced apart from the inlet of the supply channel 12a in a direction perpendicular to the first direction.

[0079] In this way, the aerosol-generating material in the storage cavity 10a can directly enter the supply channel 12a in the first direction, thereby reducing an adverse impact on efficiency of the aerosol-generating material entering the supply channel 12a due to blocking by the blocking member 13.

[0080] It may be understood that, the projection of the inlet of the supply channel 12a may be partially located on the outer side of the projection of the blocking member 13 away from the projection of the column 14; or the projection of the inlet of the supply channel 12a may be completely located on the outer side of the projection of the blocking member 13 away from the projection of the column 14.

[0081] In some embodiments in which the supply channel 12a is provided, referring to FIG. 2 and FIG. 4, the blocking member 13 is provided with a through airflow guiding channel 13d, the first end of the airflow guiding channel 13d is in communication with the storage cavity 10a, and on a projection plane perpendicular to the first direction, the projection of the inlet of the supply channel 12a is at least partially located within the projection range of the opening of the second end of the airflow guiding channel 13d.

[0082] In this way, the aerosol-generating material in the storage cavity 10a can pass through the airflow guiding channel 13d and enter the supply channel 12a, thereby reducing an adverse impact on efficiency of the aerosol-generating material entering the supply channel 12a due to blocking by the blocking member 13.

[0083] It may be understood that, in the embodiments in which the airflow guiding channel 13d is provided, the blocking member 13 may be spaced apart from the inlet of the supply channel 12a; or the blocking member 13 may be attached to the wall surface of the storage cavity 10a provided with the inlet of the supply channel 12a.

[0084] In some embodiments, the first direction is a length direction of the storage assembly 10 and the height direction of the column 14.

[0085] The length direction of the storage assembly 10 is a straight-line direction in which a maximum size value in three-dimensional sizes of the storage assembly 10 is located.

[0086] In some embodiments, the airflow guiding channel 13d is provided on the two sides of the blocking member 13 in a third direction, and the inlet of the supply channel 12a is provided on the two sides of the column 14 in the third direction, thereby improving the efficiency of the aerosol-generating material entering the supply channel 12a.

[0087] It may be understood that, during the use of the aerosol-generating device by the user, a placement direction of the storage assembly 10 has an important impact on case of the aerosol in the storage cavity 10a entering the supply channel 12a.

[0088] In some embodiments, referring to FIG. 3 and FIG. 5, the blocking member 13 includes a plurality of airflow guiding bodies 131. The plurality of airflow guiding bodies 131 are arranged on the two sides of the column 14 in a second direction. Airflow guiding bodies 131 on each side are arranged in steps and the ends of the airflow guiding bodies 131 close to the inlet of the supply channel 12a are flush. In a direction away from the column 14, the sizes of the airflow guiding bodies 131 on each side in the first direction and the sizes of the airflow guiding bodies 131 on each side in a third direction decrease step by step. An airflow guiding channel 13d is provided on at least one side of the blocking member 13 in the third direction. The first direction, the second direction, and the third direction are orthogonal.

[0089] When the aerosol-generating device is at a placement position in which the first direction is perpendicular to the direction of gravity, in a state in which the second direction is approximately the same as the direction of gravity, because the airflow guiding bodies 131 located on one side of the column 14 in the second direction are arranged in steps in the second direction and the sizes of the airflow guiding bodies 131 in the third direction decrease step by step, the aerosol-generating material is squeezed to flow to the two sides of the blocking member 13 in the third direction. In this way, a liquid level of the aerosol-generating material can be raised, so that the aerosol-generating material more easily enters the airflow guiding channel 13d located in the region. In a state in which the third direction is approximately the same as the direction of gravity, under the action of gravity, the aerosol-generating material naturally deposits on the two sides of the blocking member 13 in the third direction. In this way, the liquid level of the aerosol-generating material can be raised, so that the aerosol-generating material more easily enters the airflow guiding channel 13d located in the region.

[0090] When the aerosol-generating device is at a placement position in which the first direction is in the direction of gravity and the inlet of the supply channel 12a is located below the storage member 12, the airflow guiding bodies 131 located on one side of the column 14 in the second direction are arranged in steps and the sizes of the airflow guiding bodies 131 in the first direction decrease step by step, in other words, the blocking member 13 occupies more space in the storage cavity 10a in the second direction as the airflow guiding bodies 131 are closer to the inlet of the supply channel 12a in the first direction. Therefore, as the aerosol-generating material in the storage cavity 10a decreases, the liquid level of the aerosol-generating material can be raised under squeezing of the airflow guiding bodies 131 on the aerosol-generating material, so that the aerosol-generating material more easily enters the airflow guiding channel 13d located on one side of the column 14 in the third direction.

[0091] In this way, through arrangement of the airflow guiding bodies 131, more aerosol-generating materials can enter the supply channel 12a, thereby improving utilization of the aerosol-generating material.

[0092] In some embodiments, referring to FIG. 5, a plurality of airflow guiding protrusions 1311 are provided on the end of the airflow guiding body 131 away from the inlet of the supply channel 12a in the first direction. The two side surfaces of the airflow guiding protrusion 1311 in the third direction are airflow guiding surfaces 1311a. In a direction close to the inlet of the supply channel 12a, two airflow guiding surfaces 1311a of a same airflow guiding protrusion 1311 are away from each other in the third direction.

[0093] In this way, the aerosol-generating material in contact with the airflow guiding surfaces 1311a can flow to two sides in the third direction under the guiding action of the airflow guiding surfaces 1311a, so that the aerosol-generating material can flow into the airflow guiding channel 13d, and the efficiency of the aerosol-generating material entering the supply channel 12a can be improved.

[0094] A specific shape of the airflow guiding surface 1311a is not limited, and may be a flat surface or a circular arc surface.

[0095] Referring to FIG. 5, the end surface of the airflow guiding body 131 away from the column 14 in the second direction is a plane extending in the first direction, to improve efficiency of the aerosol-generating material flowing on the airflow guiding body 131.

[0096] A specific quantity of airflow guiding protrusions 1311 on one airflow guiding body 131 is not limited, and may be one or more. Referring to FIG. 5, the plurality of airflow guiding protrusions 1311 are arranged in the third direction.

[0097] In some embodiments, referring to FIG. 5, two airflow guiding surfaces 1311a of a same airflow guiding protrusion 1311 intersect at the end of the airflow guiding protrusion 1311 away from the inlet of the supply channel 12a. In other words, the airflow guiding protrusion 1311 forms a peak shape, to reduce a probability that the aerosol-generating material remains on a surface of the airflow guiding protrusion 1311.

[0098] In some embodiments, referring to FIG. 5, the blocking member 13 includes a tray 132, the airflow guiding body 131 is arranged on the side of the tray 132 facing away from the inlet of the supply channel 12a in the first direction, and the tray 132 and the inner wall of the storage cavity 10a block and fit in a direction using the first direction as a rotation axis, to suppress relative rotation between the blocking member 13 and the storage member 12.

[0099] It may be understood that, the airflow guiding channel 13d passes through the tray 132.

[0100] In some embodiments in which the column 14 extends in the first direction and abuts against the inlet of the supply channel 12a and the supply channel 12a is provided, referring to FIG. 6 and FIG. 7, in a direction away from the inlet of the supply channel 12a in the first direction, the cross-section area of the blocking member 13 perpendicular to the first direction gradually increases, the blocking member 13 abuts against the inlet of the supply channel 12a, and the contact area between the blocking member 13 and the inlet of the supply channel 12a is located between the column 14 and the inlet of the supply channel 12a.

[0101] In this way, when the aerosol-generating device is at a placement position in which the first direction is perpendicular to the direction of gravity, the aerosol-generating material can partially flow facing the inlet of the supply channel 12a under guidance of the outer side surface of the blocking member 13, so that the aerosol-generating material can enter the supply channel 12a in time.

[0102] A specific shape of the outer contour of the blocking member 13 is not limited; and may be an entire circular arc surface, or may be formed by splicing a plurality of planes, or may be formed by splicing a plurality of circular arc surfaces, or may be formed by splicing a plurality of circular arc surfaces and a plurality of planes.

[0103] In some embodiments, referring to FIG. 7, the end of the blocking member 13 away from the inlet of the supply channel 12a at least partially abuts against the inner wall of the storage cavity 10a in a direction perpendicular to the first direction. A probability of relative rotation between the blocking member 13 and the column 14 can be suppressed through a friction force between the blocking member 13 and the inner wall of the storage cavity 10a. In some embodiments, referring to FIG. 7, a positioning groove is provided on the inner wall of the side of the storage cavity 10a away from the inlet of the supply channel 12a in the first direction. The side of the positioning groove facing the inlet of the supply channel 12a in the first direction is open. The blocking member 13 is inserted into the positioning groove through the opening of the positioning groove, and abuts against the inner wall of the positioning groove in the first direction and the direction perpendicular to the first direction, to limit a position of the blocking member 13 in the first direction, and suppress a movement tendency of the blocking member 13 rotating relative to the inner wall of the storage cavity 10a and the column 14.

[0104] In some embodiments, the column 14 and the blocking member 13 slidably fit in an extending direction of the column 14, and the material density of the blocking member 13 is less than the density of the aerosol-generating material.

[0105] In other words, the blocking member 13 can float near the liquid level of the aerosol-generating material, and move in the extending direction of the column 14 under the action of a floating force of the aerosol-generating material.

[0106] In this way, as a content of the aerosol-generating material changes, a position of the liquid level of the aerosol-generating material changes, and the position of the blocking member 13 also changes accordingly, so that the user can determine a current stock of the aerosol-generating material in the storage cavity 10a by directly observing a floating position of the blocking member 13.

[0107] It may be understood that, after the aerosol-generating material is consumed to a certain amount, the floating force generated by the aerosol-generating material is insufficient to enable the blocking member 13 to be in a floating state.

[0108] In some embodiments, referring to FIG. 9, the blocking member 13 includes a floating ball, the floating ball is spherical, the column 14 extends in the first direction, and the inlet of the supply channel 12a and the column 14 are spaced apart in a direction perpendicular to the first direction. In this way, in a state in which the aerosol-generating material in the storage cavity 10a is consumed to a point that the aerosol-generating material cannot provide an enough floating force to enable the blocking member 13 float, because the surface of the side of the floating ball facing the inlet of the supply channel 12a is circular-arc-shaped, even if the floating ball abuts against the end surface of the atomization core 11 provided with the inlet of the supply channel 12a, the inlet of the supply channel 12a is not completely blocked. In this way, the aerosol-generating material in the storage cavity 10a can enter the supply channel 12a.

[0109] In some embodiments, referring to FIG. 8 and FIG. 9, the blocking member 13 includes a floating ball and an annular plate, the column 14 passes through the floating ball, and the annular plate is arranged around the surface of the floating ball.

[0110] The annular plate is arranged, so that the contact area between the blocking member 13 and the aerosol-generating material in the storage cavity 10a can increase, thereby suppressing the aerosol-generating material from surging to form bubbles during transportation of the aerosol-generating device.

[0111] An embodiment of the present application further provides an aerosol-generating device. Referring to FIG. 1 to FIG. 4 and FIG. 6 to FIG. 9, the aerosol-generating device includes an atomization core 11 and the storage assembly 10 in any one of the foregoing embodiments, where the power supply assembly 20 is electrically connected to the atomization core 11, the atomization core 11 is configured to atomize the aerosol-generating material to form the aerosol, and the atomization core 11 is in communication with the exhaust channel 14a.

[0112] The power supply assembly 20 is configured to supply power to the atomization core 11, so that the atomization core 11 can atomize the aerosol-generating material to form the aerosol.

[0113] The aerosol-generating material in the storage assembly 10 is discharged from the storage assembly 10 and comes into contact with the atomization core 11, the atomization core 11 atomizes the aerosol-generating material to form the aerosol, and the aerosol is then discharged from the aerosol-generating device through the exhaust channel 14a in communication with the atomization core 11, for a user to inhale.

[0114] In some embodiments, referring to FIG. 2 to FIG. 4, one side of the power supply assembly 20 is provided with a mounting cavity, one side of the mounting cavity is open, the atomization core 11 is located in the mounting cavity, and the storage member 12 is partially located in the mounting cavity and partially located outside of the mounting cavity, so that the user can observe a remaining stock of the aerosol-generating material in the storage cavity 10a of the aerosol-generating device from the outside of the aerosol-generating device.

[0115] In some embodiments, the inner wall of the mounting cavity is at least partially made of a light-transmitting material, so that a field of view in which the user observes the stock of the aerosol-generating material in the storage cavity 10a can be expanded, thereby improving user experience. The embodiments / implementations of the present application may be combined with each other without contradictions.
