[0038] It should be noted that, in the absence of conflict, the technical features in the embodiments of the present invention can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the embodiments of the present invention and should not be regarded as an improper limitation on the embodiments of the present invention.

[0039] In the description of the embodiments of the present utility model, the orientation or position relationship of the "first direction" is based on the attached Figure 3 , Figure 4 , Figure 6 , Fig.11 and Fig.12 The orientation or position relationship shown in the “second direction” is based on the Fig.11 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the embodiments of the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the utility model.

[0040] The present invention provides an atomizing assembly 10 for atomizing an aerosol generating substrate in an aerosol generating device to form an aerosol. Figure 1 , Figure 2 , Figure 3 and Figure 4 The atomizer assembly 10 includes an atomizer core 11 and a mounting seat 12 .

[0041] The atomizing core 11 is used to atomize the aerosol generating substrate stored in the aerosol generating device to form an aerosol.

[0042] The atomizing core 11 has an atomizing region 11 a , and the atomizing region 11 a can atomize an aerosol-generating substrate to form an aerosol by heating or the like.

[0043] The specific method of forming the atomization area 11a is not limited. For example, the atomization core 11 includes a substrate and a heating body. The substrate is used to contact and absorb the aerosol generating substrate. The heating body forms the atomization area 11a to generate heat so that the aerosol generating substrate in the substrate is atomized to form an aerosol.

[0044] The mounting base 12 includes a matrix channel 12a, an atomizing chamber 12b and an air outlet channel 12c. The matrix channel 12a and the air outlet channel 12c are both connected to the outside of the atomizing assembly 10 and isolated from each other. The atomizing chamber 12b has a first mold outlet 12e along a first direction and a lower liquid port 12f connected to the matrix channel 12a. The atomizing core 11 blocks the lower liquid port 12f. The air outlet channel 12c has a second mold outlet 12g and an air outlet 12h that pass through along the first direction. The second mold outlet 12g is connected to the atomizing chamber 12b.

[0045] The aerosol generating substrate stored in other components of the aerosol generating device enters the substrate channel 12a through the inlet of the substrate channel 12a located on the outer surface of the atomizing assembly 10 .

[0046] It is understandable that at least a portion of the atomizer core 11 blocked at the lower liquid port 12 f is communicated with the substrate channel 12 a , so that the aerosol-generating substrate in the substrate channel 12 a can contact the atomizer core 11 and be absorbed by the atomizer core 11 .

[0047] The substrate channel 12a and the gas outlet channel 12c are isolated from each other to prevent the aerosol-generating substrate and the aerosol from mixing with each other.

[0048] The atomizing core 11 is sealed at the lower liquid port 12f, that is, the atomizing core 11 and the mounting seat 12 are sealed to reduce the probability of the aerosol-generating matrix entering the atomizing chamber 12b.

[0049] The atomizing region 11a of the atomizing core 11 is located in the atomizing cavity 12b, so that after the atomizing region 11a atomizes the aerosol-generating matrix absorbed in the atomizing core 11 to form an aerosol, the aerosol can directly enter the atomizing cavity 12b, and the aerosol in the atomizing cavity 12b is then discharged from the atomizing assembly 10 through the air outlet channel 12c.

[0050] The first die exit 12e is located on one side of the atomization chamber 12b along the first direction, and the second die exit 12g is located on one side of the air outlet channel 12c along the second direction. That is to say, in the process of manufacturing the mounting seat 12, the mounting seat 12 is a plastic part manufactured by an injection molding process, and the injection mold presses the blank into the positive direction of the first direction. After the blank is cooled and solidified, the injection mold is demolded in the reverse direction of the first direction, so that the injection mold can be released from the molded atomization chamber 12b and the air outlet channel 12c through the first die exit 12e and the second die exit 12g, thereby molding the atomization chamber 12b and the air outlet channel 12c at least once.

[0051] It should be noted that the positive direction and the reverse direction of the first direction only refer to two opposite directions of the straight line where the first direction is located, and do not specifically refer to any one direction.

[0052] It can be understood that the second die outlet 12g is connected to the atomization chamber 12b, so that the aerosol in the atomization chamber 12b can enter the air outlet channel 12c through the second die outlet 12g and then be discharged from the air outlet 12h, that is, the second die outlet 12g is also the entrance of the air outlet channel 12c.

[0053] The atomizer assembly 10 in the embodiment of the utility model is conducive to enabling the manufacturing equipment to manufacture the atomization chamber 12b and the air outlet channel 12c only by a demolding operation along the first direction during the manufacturing process of the mounting seat 12, which is conducive to simplifying the manufacturing steps of the mounting seat 12, reducing the manufacturing difficulty and manufacturing cost, and improving production efficiency.

[0054] In some embodiments, the substrate channel 12a extends in a straight direction. On the one hand, the aerosol generating substrate entering the substrate channel 12a can flow in a straight direction, thereby improving the flow efficiency of the aerosol generating substrate and facilitating the aerosol generating substrate to contact with the atomization core 11 in a timely manner during use of the aerosol generating device, thereby reducing the probability of dry burning of the atomization core 11. On the other hand, it is helpful to reduce the manufacturing difficulty of the substrate channel 12a.

[0055] It can be understood that the second die exit 12g and the air outlet 12h are located at opposite ends of the air outlet channel 12c along the first direction. In order to facilitate demolding, the air outlet channel 12c extends in a straight line direction. On the one hand, it is beneficial to shorten the flow path of the aerosol discharged from the atomization component 10, improve the flow efficiency of the aerosol, and facilitate the user to inhale the aerosol faster during the use of the aerosol generating device, thereby improving the user experience; on the other hand, it is beneficial to the manufacturing equipment to move in a straight line along the first direction from the opening of the atomization chamber 12b to manufacture the air outlet channel 12c, thereby reducing the manufacturing difficulty.

[0056] The extension direction of the substrate channel 12a refers to the flow direction of the aerosol generating substrate in the substrate channel 12a.

[0057] The extending direction of the air outlet channel 12c refers to the flow direction of the aerosol in the air outlet channel 12c.

[0058] The atomizer core 11 and the mounting seat 12 are in a fitted state, so as to reduce the probability of relative movement between the two and improve the sealing effect between the two.

[0059] The specific material of the mounting seat 12 is not limited, for example, silicone, so that the mounting seat 12 can be elastically deformed in the aerosol generating device to improve its sealing performance and better fit with the atomizer core 11; at the same time, at least one of the matrix channel 12a and the air outlet channel 12c extends in a straight line, which is conducive to demoulding in a straight line direction during the manufacturing process, thereby reducing the manufacturing difficulty.

[0060] In some embodiments, see Figure 3 and Figure 4 The portion of the atomizing core 11 located in the substrate channel 12 a and the atomizing region 11 a are located at opposite sides of the atomizing core 11 .

[0061] That is, the portion where the atomizing core 11 communicates with the substrate channel 12a is located on a side away from the atomizing region 11a.

[0062] This is beneficial to extend the length of the joint formed between the portion of the atomizer core 11 located in the matrix channel 12a and the atomization area 11a, and between the atomizer core 11 and the mounting seat 12, which is beneficial to further improve the sealing effect of the atomizer core 11 and further help reduce the probability of the aerosol-generating matrix entering the atomization cavity 12b.

[0063] The specific number of the matrix channels 12a is not limited, and can be one or more.

[0064] In some embodiments, the substrate channel 12 a penetrates the mounting base 12 to form an inlet on surfaces of two opposite sides of the mounting base 12 .

[0065] In this way, on the one hand, it is beneficial to clean the substrate channel 12a after long-term use, reduce the probability of blockage of the substrate channel 12a, and extend the service life of the atomizer component 10; on the other hand, it is beneficial for the aerosol generating substrate to flow into the substrate channel 12a when the atomizer component 10 is placed in different positions, thereby reducing the probability of dry burning of the atomizer core 11 due to the lack of aerosol generating substrate flowing into the two inlets.

[0066] The cross-sectional shape of the matrix channel 12a perpendicular to its extension direction is not limited, for example, circular, square, rectangular, etc.

[0067] The size of the cross section of the matrix channel 12a perpendicular to its extension direction is not limited. For example, in an embodiment where the cross section is rectangular, the edge size of the cross section is not less than 4 mm (millimeter) so that the flow rate entering the matrix channel 12a meets the requirements. The specific value can be 4 mm, 5 mm, 6 mm, 7 mm, etc.

[0068] It is understandable that the dimension of the surface of one side of the atomizer core 11 blocking the matrix channel 12a perpendicular to the extension direction of the matrix channel 12a is greater than the dimension of the cross section of the matrix channel 12a perpendicular to its extension direction at the side edge. For example, the dimension of the cross section of the matrix channel 12a perpendicular to its extension direction at the side edge is 4 mm, and the dimension of the surface of one side of the atomizer core 11 blocking the matrix channel 12a perpendicular to the extension direction of the matrix channel 12a is 6 mm, so as to improve the sealing effect.

[0069] The specific number of the air outlet channels 12c is not limited, and can be one or more.

[0070] In some embodiments, see Figure 4 The air outlet channel 12c and the matrix channel 12a are both located on the side of the atomization chamber 12b away from the first die outlet 12e along the first direction. There are at least two air outlet channels 12c, and the two air outlet channels 12c are arranged at intervals. The matrix channel 12a is located between the two air outlet channels 12c.

[0071] That is to say, the air outlet channel 12c and the matrix channel 12a are located on the same side of the atomizing chamber 12b, and are arranged alternately, which is conducive to more fully utilizing the space of the atomizing assembly 10, making the structure of the mounting base 12 more compact, and improving the adaptability of the atomizing assembly 10.

[0072] By using multiple air outlet channels 12c, each air outlet channel 12c can serve as a backup for each other, thereby reducing the probability that the aerosol condensed in the atomizing chamber 12b blocks the air outlet channel 12c and fails to remove the aerosol, which is beneficial to extending the service life of the atomizing assembly 10.

[0073] In some embodiments, see Figure 3 and Figure 4 The matrix channel 12a extends along the second direction and is located on the side of the atomization cavity 12b away from the first die outlet 12e along the first direction, and the first direction and the second direction are orthogonal.

[0074] This helps to reduce the size of the atomizer assembly 10 along the first direction, making the structure of the atomizer assembly more compact.

[0075] In some embodiments, see Figure 4 and Figure 5The atomizing chamber 12b includes a mounting groove 12d, one side of the mounting groove 12d is open along the first direction and a bottom wall of the other side is provided with a lower liquid port 12f, and the atomizing core 11 is embedded in the mounting groove 12d and sealed with the inner wall of the mounting groove 12d.

[0076] On one hand, the atomizer core 11 can abut against the bottom wall of the installation groove 12d provided with the lower liquid port 12f along the first direction; on the other hand, the atomizer core 11 can abut against the side wall of the installation groove 12d perpendicular to the first direction.

[0077] Thus, on the one hand, the inner walls of the mounting groove 12d in all directions constrain the position of the atomizer core 11, reducing the probability of functional failure caused by the position change between the atomizer core 11 and the mounting seat 12 during use; on the other hand, the seam between the atomizer core 11 and the mounting seat 12 is bent and extended, further reducing the probability of the aerosol-generating matrix penetrating into the atomizer cavity 12b from the seam position. Furthermore, it is convenient to put the atomizer core 11 into the mounting groove 12d from the opening of the atomizer cavity 12b, thereby simplifying the assembly operation steps.

[0078] The present invention also provides an aerosol generating device. Figures 6 to 12 The aerosol generating device includes a storage component 30 and an atomization component 10 of any one of the aforementioned embodiments.

[0079] The storage assembly 30 comprises a supply channel 30a, an exhaust channel 30c and a storage chamber 30b for storing an aerosol generating substrate, wherein the supply channel 30a is communicated with the storage chamber 30b, and the exhaust channel 30c is communicated with the outside of the aerosol generating device.

[0080] The aerosol-generating substrate stored in the storage chamber 30b is used to supply the atomizing assembly 10. The storage assembly 30 may be provided with fewer or no other devices having functions such as electric control and atomization, thereby reducing the manufacturing cost of the storage assembly 30.

[0081] The supply channel 30a is communicated with the substrate channel 12a, and the exhaust channel 30c is communicated with the exhaust channel 12c.

[0082] That is to say, the aerosol-generating substrate in the storage chamber 30b can contact the atomizing core 11 through the supply channel 30a and the substrate channel 12a in turn; the aerosol generated in the atomizing area 11a and thus the atomizing chamber 12b can be discharged from the aerosol generating device through the air outlet channel 12c and the exhaust channel 30c in turn for the user to inhale.

[0083] In this way, the replenishment of the aerosol generating substrate to the atomizing core 11 and the aerosol discharge in the aerosol generating device do not interfere with each other.

[0084] It should be noted that the specific connection relationship between the storage component 30 and the atomization component 10 in the aerosol generating device is not limited.

[0085] For example, the storage component 30 and the atomization component 10 are fixedly connected after manufacturing and assembly are completed, that is, it is difficult or impossible for a user to separate the two. In other words, the assembly formed by the two is used once, and the assembly formed by the two can be fixedly connected to other parts of the aerosol generating device after manufacturing and assembly are completed. In other words, the entire aerosol generating device is disposable to reduce the manufacturing cost of the aerosol generating device; it is also possible that the assembly formed by the two can be detachably connected to other parts of the aerosol generating device. In this way, after the aerosol generating matrix in the storage component 30 is exhausted, the assembly formed by the storage component 30 and the atomization component 10 can be replaced to replenish the aerosol generating matrix.

[0086] For another example, the storage component 30 and the atomizer component 10 are detachably configured, that is, after the aerosol generating matrix in the storage component 30 is exhausted, it is only necessary to replace the storage component 30 to achieve the purpose of replenishing the aerosol generating matrix of the aerosol generating device, while the atomizer component 10 can continue to be used, thereby reducing the user's replacement cost and improving the user experience.

[0087] In some embodiments, see Figures 6 to 12 The aerosol generating device also includes a shell 20, which is provided with an installation cavity 20a. One side of the installation cavity 20a is opened to form an installation port 20b. The storage component 30 is detachably connected to the shell 20 and can enter and exit the installation cavity 20a through the installation port 20b. The atomization component 10 is arranged in the installation cavity 20a.

[0088] At least a portion of the outer surface of the housing 20 forms the appearance of the aerosol generating device to protect other components of the aerosol generating device. For example, the atomizer assembly 10 is located in the mounting cavity 20 a to protect the atomizer assembly 10 .

[0089] The storage assembly 30 can completely enter the installation cavity 20a along the first direction through the installation opening 20b, that is, the storage assembly 30 is completely located in the installation cavity 20a; alternatively, a portion of the storage assembly 30 enters the installation cavity 20a and a portion of the storage assembly 30 is located outside the installation cavity 20a.

[0090] By means of the detachable connection between the storage component 30 and the shell 20, after the aerosol generating matrix in the storage component 30 is exhausted, the purpose of replenishing the aerosol generating matrix can be achieved by simply replacing the storage component 30, thereby extending the service life of the aerosol generating device, facilitating the reuse of components such as the atomization component 10 in the aerosol generating device, and helping to reduce the use cost and environmental pollution.

[0091] In some embodiments, see Figure 7 , Figure 8 and Fig. 9 The supply channel 30a is located on the side of the storage chamber 30b close to the atomizer assembly 10, which is conducive to shortening the size of the supply channel 30a so that the aerosol generating matrix in the storage chamber 30b can enter the matrix channel 12a more quickly, thereby improving the user experience and reducing the probability of dry burning of the atomizer core 11.

[0092] In some embodiments, see Fig.13 The storage assembly 30 is provided with a accommodating chamber 30f, which is open on one side along the first direction. Part or all of the atomizer assembly 10 can enter the accommodating chamber 30f through the opening of the accommodating chamber 30f and seal with the inner wall of the accommodating chamber 30f. The supply channel 30a and the exhaust channel 30c are both connected to the accommodating chamber 30f.

[0093] In this way, by extending at least part of the atomizer assembly 10 into the accommodating chamber 30f, it is convenient to achieve positioning during the installation of the storage assembly 30, thereby reducing the probability of misalignment between the atomizer assembly 10 and the storage assembly 30, which may cause the aerosol generating device to fail to work normally. At the same time, by sealing the atomizer assembly 10 with the inner wall of the accommodating chamber 30f, the connection between the supply channel 30a and the exhaust channel 30c is reduced, thereby reducing the probability of leakage of the aerosol generating matrix or contamination of the aerosol generating matrix by foreign matter such as external dust and germs.

[0094] It is understandable that it is necessary for the aerosol generating substrate to flow smoothly from the supply channel 30a into the substrate channel 12a.

[0095] For example, see Figure 7 , Figure 8 and Fig. 9 The supply channel 30a and the substrate channel 12a both extend in a straight direction, that is, the aerosol generating substrate in the storage chamber 30b can flow directly into the substrate channel 12a in a straight direction, thereby improving the flow efficiency of the aerosol generating substrate and facilitating the aerosol generating substrate to contact with the atomizing core 11 in a timely manner during use of the aerosol generating device, thereby reducing the probability of dry burning of the atomizing core 11.

[0096] The extending direction of the supply channel 30a refers to the flow direction of the aerosol generating substrate in the supply channel 30a.

[0097] In some embodiments, see Fig.10 and Fig.11 On a projection plane perpendicular to the extension direction of the supply channel 30a, the projection of the supply channel 30a coincides with the projection of the matrix channel 12a.

[0098] This is helpful to reduce the probability of the aerosol generating substrate being obstructed at the connection position between the supply channel 30a and the substrate channel 12a, further improving the flow efficiency of the aerosol generating substrate, and facilitating the aerosol generating substrate to contact with the atomizer core 11 in a timely manner during use of the aerosol generating device, thereby reducing the probability of dry burning of the atomizer core 11.

[0099] In some embodiments, see Figure 8 and Fig.10 The aerosol generating device further includes a power supply assembly 40, and the atomizing assembly 10 is disposed at one end of the power supply assembly 40 along the first direction and is electrically connected to the power supply assembly 40. The atomizing assembly 10 is powered by the power supply assembly 40, so that the atomizing assembly 10 can atomize the aerosol generating matrix to generate an aerosol; at the same time, the disassembly and assembly of the storage assembly 30 along the first direction is unlikely to affect the electrical connection between the atomizing assembly 10 and the power supply assembly 40, thereby reducing the risk of problems such as short circuits between the two.

[0100] It is understandable that, when the user inhales the aerosol, the external gas needs to enter the aerosol generating device and mix with the aerosol in the atomizing chamber 12b before being discharged from the aerosol generating device.

[0101] In some embodiments, see Fig. 9 and Fig.11 The power supply component 40 is provided with an air inlet channel 40a, and the outlet of the air inlet channel 40a is provided at one end of the power supply component 40 along the first direction, the atomization component 10 is covered at the outlet of the air inlet channel 40a, and the first outlet port 12e is connected to the air inlet channel 40a.

[0102] The inlet of the air inlet passage 40a communicates with the outside of the aerosol generating device.

[0103] During the user's inhalation, negative pressure is formed in the aerosol generating device, so that external gas enters through the entrance of the air inlet channel 40a and enters the atomization chamber 12b from its outlet. The gas entrains the aerosol generated by atomization in the atomization chamber 12b and enters the user's mouth through the air outlet channel 12c and the exhaust channel 30c in turn.

[0104] The specific method of supplying power to the atomizer core 11 is not limited.

[0105] For example, see Fig. 9 A portion of the power supply assembly 40 extends into the atomizing chamber 12b and is electrically connected to the atomizing core 11, so that during the installation of the atomizing assembly 10, the electrical connection between the power supply assembly 40 and the atomizing core 11 and the communication between the atomizing chamber 12b and the air inlet channel 40a can be completed simultaneously, which is conducive to simplifying the assembly steps.

[0106] It can be understood that a portion of the power supply assembly 40 extends into the atomization chamber 12b through the first die outlet 12e.

[0107] In some embodiments, see Figure 8 and Fig. 9 The power supply assembly 40 includes a pole 41 and a battery 42 . One end of the pole 41 is electrically connected to the battery 42 , and the other end of the pole 41 extends into the atomizing chamber 12 b and is electrically connected to the atomizing core 11 .

[0108] In some embodiments, see Fig.10 and Fig.11 , the exhaust channel 30c and the outlet channel 12c both extend along the first direction.

[0109] In this way, after the storage component 30 reaches the preset installation position along the first direction, the exhaust channel 30c and the air outlet channel 12c can be directly connected, reducing the probability of the aerosol being unable to be discharged smoothly due to misalignment between the two; the exhaust channel 30c and the air outlet channel 12c have the same extension direction, which is beneficial to improving the discharge efficiency of the discharged aerosol.

[0110] In some embodiments, see Fig.11 The second mold outlet 12g is located on the inner wall of the atomizing chamber 12b on one side away from the power supply assembly 40 along the first direction. In this way, the airflow can be discharged roughly along the first direction through the atomizing chamber 12b, the air outlet channel 12c, and the exhaust channel 30c in sequence, which is beneficial to reduce the probability of the airflow turning during the flow process and to reduce the suction resistance.

[0111] In some embodiments, see Fig.11 On the projection plane perpendicular to the first direction, the projection of the outlet of the air inlet channel 40a is outside the projection range of the air outlet channel 12c, which is conducive to the gas entering the atomization chamber 12b and mixing with the aerosol more fully before being discharged through the air outlet channel 12c, which is conducive to improving the user experience.

[0112] In some embodiments, see Fig.11 The exhaust channel 30c includes a confluence sub-channel 30d and an exhaust sub-channel 30e. The exhaust sub-channel 30e extends along the first direction and is connected to the outside of the aerosol generating device. The confluence sub-channel 30d is located at one end of the exhaust sub-channel 30e close to the mounting seat 12 along the first direction. The end of the confluence sub-channel 30d close to the mounting seat 12 along the first direction is open to form a confluence port. On the projection plane perpendicular to the first direction, the projection of the outlet of the air outlet channel 12c is located within the projection range of the confluence sub-channel 30d.

[0113] In this way, in the process of placing the storage component 30 along the first direction, the confluence channel 30d is directly covered on the outlet of the air outlet channel 12c to enable the exhaust channel 30c and the air outlet channel 12c to be connected, thereby reducing the probability of misalignment between the exhaust channel 30c and the air outlet channel 12c, and facilitating the smooth discharge of the aerosol out of the aerosol generating device.

[0114] In some embodiments, on the projection plane perpendicular to the first direction, the projection of the discharge sub-channel 30e is located within the projection range of the confluence sub-channel 30d, that is, the cross-sectional area of ​​the discharge sub-channel 30e perpendicular to the first direction is smaller than the cross-sectional area of ​​the confluence sub-channel 30d perpendicular to the first direction.

[0115] In this way, under the premise that the volume of the storage component 30 is constant, it is beneficial to reduce the volume of the discharge sub-channel 30e and increase the volume of the storage cavity 30b, thereby increasing the capacity of the aerosol generating matrix and extending the service life of the storage component 30.

[0116] The specific position of the conduit channel 30d is not limited.

[0117] For example, see Fig.11 and Fig.13 The storage assembly 30 is provided with a accommodating chamber 30f, part or all of the atomizer assembly 10 is located in the accommodating chamber 30f and is sealed and fitted with the inner wall of the accommodating chamber 30f, a groove 30g is provided on the inner wall of the accommodating chamber 30f along the first direction, and the groove 30g is open on one side along the first direction to communicate with the air outlet 12h, and the entrance of the discharge sub-channel 30e is located on the inner wall of the groove 30g along the first direction, and the groove 30g forms a confluence sub-channel 30d.

[0118] That is to say, the air outlet 12h is connected to the groove 30g. In this way, on the one hand, the sealing fit between the atomizer component 10 and the accommodating chamber 30f reduces the probability of leakage of the aerosol after flowing out from the air outlet 12h; on the other hand, after the storage component 30 is installed to the preset installation position relative to the atomizer component 10 along the first direction, the air outlet 12h can be directly connected to the confluence channel 30d, reducing the difficulty of assembly.

[0119] Various embodiments / implementations of the present invention can be combined with each other without causing any contradiction.
