[0035] The technical solutions of the present application will be further described in detail below with specific embodiments and accompanying drawings. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by ingredients, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail according to the description in the specification and general technical knowledge in the art.

[0036] For the convenience of understanding the technical solutions of the present application, the width direction of the atomization device is defined as the X-axis direction, the thickness direction of the atomization device is defined as the Y-axis direction, and the height direction of the atomization device is defined as the Z-axis direction, which is consistent with the direction of gravity.

[0037] Referring to Figures 1-2 In some embodiments of the present application, a liquid storage bin is provided, which comprises a bin body 11, an atomization assembly 20, and a baffle 112. The bin body 11 defines a first accommodating space 111.

[0038] The atomization assembly 20 is arranged in the first accommodating space 111 and defines a liquid storage cavity with the first accommodating space 111. The liquid storage cavity is configured to store a first atomization substrate. The first atomization substrate is in a liquid state and has fluidity.

[0039] Referring to Figure 2 The baffle 112 is arranged in the liquid storage cavity and is configured to divide the liquid storage cavity into an upper chamber 113 and a lower chamber 114. The baffle 112 can form a blocking effect on the first atomization substrate in the liquid storage cavity.

[0040] The baffle 112 is provided with a first through hole 1121, which is configured to communicate the upper chamber 113 and the lower chamber 114.

[0041] It should be noted that the "upper" and "lower" in the present application refer to the upper part in the direction of gravity and the lower part in the direction of gravity. The upper chamber 113 refers to the chamber in the upper part of the liquid storage cavity in the direction of gravity, and the lower chamber 114 refers to the chamber in the lower part of the liquid storage cavity in the direction of gravity. The first atomization substrate in the upper chamber 113 can automatically flow to the lower chamber 114 under the action of gravity through the first through hole 1121, thereby ensuring the normal liquid supply of the atomization assembly 20.

[0042] The liquid storage bin of the present application forms a blocking effect on the first atomization substrate through the baffle 112, significantly reduces the fluctuation amplitude of the first atomization substrate and the generation of shock waves, effectively alleviates the impact of the first atomization substrate on the atomization assembly 20 when the liquid storage bin shakes or vibrates, avoids the adverse effects of shock waves on the liquid locking effect of the atomization assembly 20 itself, significantly reduces the risk of liquid leakage of the liquid storage bin, and improves the user experience.

[0043] The first through hole 1121 is arranged at least one, and a plurality of first through holes 1121 can be uniformly distributed on the baffle 112 or arranged according to the use requirements. The diameters of different first through holes 1121 can be the same or different, and the present application does not make any limitation thereon, as long as the upper chamber 113 and the lower chamber 114 can be communicated through the first through hole 1121.

[0044] Referring to 1 to Figure 3In some embodiments, the atomization assembly 20 comprises a tube body 21, a liquid guide 22, the tube body 21 being in communication with the first containing space 111 and the external space, and the tube body 21 being configured to allow airflow to pass through, so that the airflow in the external space can flow through the tube body 21, the atomization assembly 20 and the first containing space 111.

[0045] The liquid guide 22 is arranged in the tube body 21 and used to adsorb the first atomization substrate.

[0046] The tube wall of the tube body 21 is provided with at least one liquid inlet (not labeled), and the liquid inlet is configured to communicate the liquid storage cavity and the liquid guide 22, so that the first atomization substrate can automatically flow to the liquid guide 22 through the liquid inlet, and the liquid path between the liquid guide 22 and the liquid storage cavity is communicated.

[0047] The tube body 21 is in communication with the first containing space 111 on one side, and forms a converging and fixing effect on the liquid guide 22 on the other side, thereby realizing the gas path communication between the atomization assembly 20 and the external space.

[0048] Please refer to Figures 1-2 In some embodiments, the baffle 112 is fixedly connected between the outer wall surface of the tube body 21 and the inner wall surface of the first containing space 111.

[0049] The liquid inlet communicates the lower chamber 114 and the liquid guide 22.

[0050] The liquid inlet communicates the lower chamber 114 and the liquid guide 22, and the flow of the first atomization substrate from the upper chamber 113 to the lower chamber 114 per unit time can be controlled by adjusting the number of first through holes 1121 and the size of the first through holes 1121, thereby realizing the liquid suction control of the liquid guide 22 and preventing excessive first atomization substrate from entering the liquid guide 22 through the liquid inlet per unit time, which can cause the liquid guide 22 to be oversaturated, thereby significantly reducing the risk of liquid leakage of the atomization assembly 20 due to oversaturation.

[0051] The liquid inlet is preferably arranged close to the gravity direction lower end of the tube body 21, so as to ensure that there is no excessive first atomization substrate remaining in the lower chamber 114 after the first atomization substrate is consumed. The baffle 112 is arranged close to the liquid inlet, so that the volume of the lower chamber 114 is smaller than that of the upper chamber 113, which is conducive to controlling the liquid suction amount of the liquid guide 22 per unit time and further reducing the risk of liquid leakage of the atomization assembly 20 due to oversaturation.

[0052] The baffle 112 is preferably inclined downward from one end of the tube body 21 to one end of the inner wall surface of the first containing space 111, so that the baffle 112 forms an umbrella-shaped structure, which is conducive to the atomization substrate in the upper chamber 113 flowing to the lower chamber 114 under the action of gravity, thereby ensuring the continuity and stability of the liquid supply of the lower chamber 114 to the atomization assembly 20.

[0053] Referring to Figure 1 In some embodiments, the liquid storage bin further comprises a wave breaker 115, which is arranged in the upper chamber 113 and has a gap between the outer wall of the tube body 21 or the inner wall of the first containing space 111, and the gap is configured for the first atomized substrate to flow to the lower chamber 114.

[0054] Since the baffle 112 is arranged close to the liquid inlet, the upper chamber 113 has a relatively larger volume than the lower chamber 114. During early use, the upper chamber 113 has a larger storage of the first atomized substrate, and in the case of abnormal shaking and vibration of the liquid storage bin, the fluctuation amplitude of the first atomized substrate in the upper chamber 113 is large, and the shock wave is strong. Due to the fluidity of the liquid, it will seriously affect the stability of the first atomized substrate in the lower chamber 114.

[0055] The wave breaker 115 is a plate structure, which can form a blocking effect on the first atomized substrate in the upper chamber 113, significantly reduce the fluctuation amplitude of the first atomized substrate in the upper chamber 113 and the generation of shock wave, significantly reduce the adverse effects of the first atomized substrate in the upper chamber 113 on the first atomized substrate in the lower chamber 114, alleviate the impact of the first atomized substrate in the lower chamber 114 on the liquid guide 22, and further reduce the risk of liquid leakage of the liquid storage bin.

[0056] The wave breaker 115 is arranged at least one, and multiple wave breakers 115 can be arranged equidistantly along the axial direction of the tube body 21, or arranged non-equidistantly along the axial direction of the tube body 21, or arranged staggeredly around the circumferential direction of the tube body 21, which is not limited in the present application, as long as it meets the actual use requirements.

[0057] In some embodiments, the projection area of the wave breaker 115 on the vertical cross section of the liquid storage cavity is less than half of the vertical cross section area of the liquid storage cavity, so as to ensure that the first atomized substrate in the upper chamber 113 can flow smoothly to the lower chamber 114, and ensure that the lower chamber 114 can continuously and stably supply liquid to the atomization assembly 20.

[0058] Referring to Figures 2-3 In some embodiments, the tube body 21 comprises a first tube body 211 and a second tube body 212, the first tube body 211 is fixedly connected in the first containing space 111, and the liquid inlet comprises at least one first liquid inlet 2111 (as shown in Figure 3 Fig. 1) arranged on the wall of the first tube body 211. The first liquid inlet 2111 is preferably arranged close to the lower end of the first tube body 211 and in the lower chamber 114, and the baffle 112 is arranged close to the first liquid inlet 2111.

[0059] The second tube body 212 is arranged in the first tube body 211, and the liquid inlet further comprises at least one second liquid inlet 2121 (as shown in Figure 3

[0060] The liquid guide 22 is at least partially fixed and clamped between the first tube body 211 and the second tube body 212, and the liquid guide 22 at least partially seals the first liquid inlet 2111 and the second liquid inlet 2121.

[0061] The tube body 21 adopts an inner and outer double tube body 21 nested structure, which at least partially fixes and clamps the liquid guide 22 between the first tube body 211 and the second tube body 212, and seals the first liquid inlet 2111 and the second liquid inlet 2121 through the liquid guide 22. The double tube body 21 nested structure has stronger structural strength than a single tube body, which can better support the liquid guide 22, improve the reliability and stability of the fixed connection between the tube body 21 and the liquid guide 22, and on the other hand, also improves the reliability of the liquid guide 22 sealing the liquid inlet, further reducing the risk of liquid leakage of the atomization assembly 20.

[0062] Please refer to Figures 2-3 In some embodiments, the liquid guide 22 comprises a first liquid guide 221 and a second liquid guide 222, and an atomization air channel 2221, the first liquid guide 221 is fixed and clamped between the first tube body 211 and the second tube body 212, and at least partially seals the first liquid inlet 2111 from the inside and at least partially seals the second liquid inlet 2121 from the outside.

[0063] The second liquid guide 222 is arranged in the second tube body 212 and at least partially seals the second liquid inlet 2121 from the inside.

[0064] The atomization air channel 2221 is arranged on the second liquid guide 222 and is configured to allow airflow to pass through.

[0065] In use, the first atomization substrate in the lower chamber 114 flows to the first liquid guide 221 through the first liquid inlet 2111, and then is transmitted to the second liquid guide 222 by the first liquid guide 221 through the second liquid inlet 2121, and finally is transmitted to the atomization air channel 2221 by the second liquid guide 222.

[0066] The liquid guide 22 adopts an inner and outer double-layer structure design, has a larger liquid absorption amount, and has better liquid guiding and locking effects, further reducing the risk of liquid leakage of the atomization assembly 20.

[0067] In actual manufacture, the first liquid guide 221 on the outside and the second liquid guide 222 on the inside can be made of different materials and different porosity porous materials, so that the first liquid guide 221 and the second liquid guide 222 have different liquid absorption and liquid guiding characteristics, to improve the liquid guiding efficiency and improve the atomization effect. ​

[0068] Referring to Figures 4-5 In some embodiments of the present application, an atomization device 100 is provided, which comprises a housing 10 having an air inlet 12 (as shown in Figure 5 Fig. 1) and an air outlet 13, a liquid storage tank as any of the above, wherein the tank body 11 is formed in the housing 10, an atomization assembly 20 is in air communication with the air inlet 12 and the air outlet 13, and the atomization assembly 20 is in liquid communication with the liquid storage cavity for atomizing a first atomization substrate and generating a first aerosol.

[0069] In use, a user sucks the air outlet 13 to generate a negative pressure in the housing 10, and the airflow outside the housing 10 enters from the air inlet 12, carries the generated first aerosol when flowing through the atomization air channel 2221 of the atomization assembly 20, and is finally discharged from the air outlet 13 for the user to smoke.

[0070] The atomization device 100 provided by the present application has the above-mentioned liquid storage tank, which can form a blocking effect on the first atomization substrate through the baffle 112 during use, significantly reducing the risk of liquid leakage of the liquid storage tank due to shaking, vibration, etc., and improving the user experience.

[0071] Referring to Figures 2-3 , Figure 5 In some embodiments, the atomization assembly 20 further comprises a first heating member 23, which is accommodated in the atomization air channel 2221 and at least partially abuts the second liquid guide member 222, for heating and atomizing the first atomization substrate transmitted by the second liquid guide member 222 to the atomization air channel 2221 and generating a first aerosol.

[0072] The air inlet end of the atomization air channel 2221 is in communication with the air inlet 12 through the air inlet end of the tube body 21, and the air outlet end of the atomization air channel 2221 is in communication with the air outlet 13 through the air outlet end of the tube body 21, and the first aerosol is generated in the atomization air channel 2221.

[0073] The liquid guide member 22 adsorbs the first atomization substrate in the liquid storage cavity through its own liquid absorption characteristics, and transmits the adsorbed first atomization substrate to the atomization air channel 2221, and the first heating member 23 heats the first atomization substrate transmitted to the atomization air channel 2221 by contact heating to atomize, and generates a first aerosol in the atomization air channel 2221.

[0074] Referring to Figures 1-2 , Figure 5In some embodiments, the liquid storage bin further comprises a first fixed groove 116 and a second fixed groove 117 arranged along the Z-axis, the first fixed groove 116 is arranged at the bottom of the first accommodating space 111, and the second fixed groove 117 is arranged at the top of the first accommodating space 111. The first fixed groove 116 and the second fixed groove 117 are coaxially arranged, and the first fixed groove 116 is provided with a first through hole 1161 penetrating therethrough, and the second fixed groove 117 is provided with a second through hole 1171 penetrating therethrough. The first through hole 1161 is in communication with the gas inlet 12 and is configured to allow the gas flow to flow from the gas inlet 12 into the first accommodating space 111; the second through hole 1171 is in communication with the gas outlet 13 and is configured to allow the gas flow to flow out of the first accommodating space 111.

[0075] The atomization assembly 20 is fixedly connected between the first fixed groove 116 and the second fixed groove 117 along the Z-axis. The atomization air channel 2221 axially penetrates the second liquid guide 222, and the gas inlet end of the atomization air channel 2221 is in communication with the gas inlet 12 through the first through hole 1161, and the gas outlet end of the atomization air channel 2221 is in communication with the gas outlet 13 through the second through hole 1171, so as to realize the gas path communication of the atomization assembly 20, the gas inlet 12 and the gas outlet 13.

[0076] The atomization assembly 20 is accommodated in the first accommodating space 111, which is beneficial to improve the utilization rate of the internal space of the atomization device 100, and is beneficial to the adsorption of the first atomization substrate from the liquid storage cavity by the liquid guide 22, thereby ensuring the continuous and stable supply of the first atomization substrate and the continuous and stable generation of the first aerosol.

[0077] Please refer to Figures 2-3 In some embodiments, the atomization assembly 20 further comprises a sealing member 24 and an air guide member 25. The lower end of the first pipe body 211 is inserted and fixed in the first fixed groove 116, the upper end of the first pipe body 211 is inserted and fixed in the second fixed groove 117, and the second pipe body 212 is accommodated in the first pipe body 211. The sealing member 24 is sealingly clamped between the bottom of the first pipe body 211, the bottom of the second pipe body 212 and the bottom surface of the first fixed groove 116, so as to prevent the first atomization substrate on the first liquid guide 221 from leaking out of the first accommodating space 111 through the first through hole 1161.

[0078] The air guide member 25 is accommodated in the second pipe body 212 and located at the gas inlet end of the second pipe body 212. The air guide member 25 is provided with a first air guide through hole 251 penetrating axially, and the outer wall surface of the air guide member 25 is circumferentially provided with a plurality of air guide grooves 252 (such as Figure 3As shown in FIG. 6, the air guide grooves 252 are arranged in a continuous tooth groove shape in the circumferential direction of the air guide member 25. The air guide grooves 252 and the inner wall of the second tube body 212 define a plurality of second air guide holes (not shown). The air flow entering through the first air guide hole 1161 flows to the atomization air passage 2221 through the first air guide hole 251 and the second air guide hole, realizing multi-channel air inlet of the atomization assembly 20. The air flow flowing through the first air guide hole 251 has a faster flow rate, the air flow flowing through the second air guide hole has a relatively slower flow rate and smaller flow rate, so that the atomization assembly 20 can realize multi-channel air inlet and form a flow rate difference, reducing the risk of oil explosion caused by the air flow directly passing through the atomization air passage 2221.

[0079] Referring to FIG. 1, the aerosol generating device 100 includes a housing 10, an atomization assembly 20 arranged in the housing 10, and a second aerosol generating assembly 30 arranged in the housing 10. Figure 5 In some embodiments, the atomization device 100 further includes a second aerosol generating assembly 30 arranged in the housing 10, and the second aerosol generating assembly 30 includes at least one second containing space 310 configured to store a second atomization substrate configured to provide a second aerosol with a preset odor.

[0080] At least one of the first aerosol and the second aerosol is discharged through the air outlet 13; or the first aerosol and the second aerosol are mixed and then discharged through the air outlet 13.

[0081] The second atomization substrate is different from the first atomization substrate, and the second atomization substrate contains an effective component with a preset odor. The second atomization substrate can be configured to volatilize a second aerosol with a preset odor at room temperature, or can be configured to atomize a second aerosol with a preset odor under heating conditions.

[0082] In use, the air flow enters the inside of the housing 10 from the air inlet 12. The air flow can be configured to flow only through the atomization assembly 20; or the air flow can be configured to flow only through the second aerosol generating assembly 30; or the air flow can be configured to flow partially through the atomization assembly 20 and partially through the second aerosol generating assembly 30; and finally all the air flow is discharged through the air outlet 13.

[0083] When the airflow is configured to flow through the atomization assembly 20 only, only the first aerosol is discharged from the air outlet 13, and the user is provided with the first aerosol having specific functions and effects alone; when the airflow is configured to flow through the second aerosol generating assembly 30 only, only the second aerosol is discharged from the air outlet 13, and the user is provided with the second aerosol having a preset odor alone; when the airflow is configured to flow through the atomization assembly 20 partially and the second aerosol generating assembly 30 partially, the first aerosol and the second aerosol are mixed and discharged through the air outlet 13, providing the user with a mixed aerosol having a preset odor, functions and effects, enriching the taste of the aerosol that the atomization device 100 can provide, improving the smoking taste, meeting the diversified and personalized use requirements of the user, and improving the user experience.

[0084] The second aerosol generating assembly 30 can include only one second containing space 310, or can include a plurality of second containing spaces 310. The same odor second atomization substrate can be stored in different second containing spaces 310, or different odor second atomization substrates can be stored in different second containing spaces 310, which is not limited in the present application, and can meet the actual use requirements of the user.

[0085] In the following embodiments, the first atomization substrate is taken as an example of the smoke oil containing a smoking agent and a tobacco component or a tobacco substitute component, the second aerosol generating assembly 30 includes a plurality of second containing spaces 310, and different second containing spaces 310 store second atomization substrates with different odors. The second atomization substrate is taken as an example of the fragrance liquid containing volatile fragrance components, and the second atomization substrate can automatically emit the second aerosol with a preset fragrance odor at room temperature. The smoke oil provides the user with the first aerosol having the tobacco component or the tobacco substitute component and the smoke, and the fragrance liquid provides the user with the second aerosol having a preset fragrance odor.

[0086] Please refer to Figures 5-6 In some embodiments, the second aerosol generating assembly 30 includes a rotating member 31 and at least two second containing spaces 310. The rotating member 31 is movably connected in the housing 10 and is configured to rotate around the central axis 311 (as shown in Figure 6 The second containing space 310 is arranged circumferentially around the central axis 311 of the rotating member 31 and is used for storing the second atomization substrate.

[0087] The end of the rotating member 31 facing the air inlet 12 is provided with a plurality of second air inlets 312 (as Figure 5The rotating member 31 is provided with a plurality of second air outlet holes 341 at one end thereof facing the air outlet 13, the second air inlet holes 312 are connected between the air inlet 12 and the corresponding second accommodating spaces 310, and the second air outlet holes 341 are connected between the corresponding second accommodating spaces 310 and the air outlet 13. The rotating member 31 rotates around the central axis 311 thereof to rotate at least one second accommodating space 310 to a set position, and the second accommodating space 310 in the set position is connected in air flow communication with the air inlet 12 and the air outlet 13 through the corresponding second air inlet holes 312 and the second air outlet holes 341.

[0088] In use, the user manually drives the rotating member 31 to rotate, rotates the second accommodating space 310 storing the second atomized substrate with a preset fragrance to a set position, and the air flow entering through the air inlet 12 enters the second accommodating space 310 in the set position through the corresponding second air inlet holes 312, carries out the second aerosol, and then is discharged from the corresponding second air outlet holes 341. The second aerosol can be configured to be mixed with the first aerosol and discharged from the air outlet 13 to provide the user with a mixed aerosol with a preset fragrance, tobacco components or tobacco substitute components; or the second aerosol can also be configured to be discharged from the air outlet 13 alone to provide the user with the first aerosol with a preset fragrance.

[0089] The user can independently switch the second accommodating space 310 in air flow communication with the air inlet 12 and the air outlet 13 by rotating the rotating member 31, thereby changing the fragrance of the first aerosol discharged from the air outlet 13, realizing fragrance conversion, and the operation of switching the fragrance is simple and convenient, meets the diversified and personalized use requirements of the user, and improves the user experience.

[0090] The second atomized substrate can be any one or more physical forms of solid, semi-solid or liquid, which is not limited in the present application, and can volatilize the first aerosol with a preset fragrance at room temperature. It should be noted that the room temperature in the present application refers to the general room temperature, and the temperature range is between 10°C and 35°C.

[0091] Please refer to Figures 5-6 In some embodiments, the second aerosol generating assembly 30 further comprises a liquid storage element 32, the number of the liquid storage elements 32 is preferably matched with the number of the second accommodating spaces 310, and the liquid storage elements 32 are accommodated in the corresponding second accommodating spaces 310 to adsorb the liquid second atomized substrate. The hollow channels 321 are provided on the liquid storage elements 32 (as shown in FIG. 6) and are connected between the second air inlet holes 312 and the second air outlet holes 341. Figure 6 The hollow channels 321 are connected between the second air inlet holes 312 and the second air outlet holes 341.

[0092] The liquid storage element 32 is made of a porous material and absorbs the liquid second atomization base through its liquid absorption property, reducing the risk of leakage of the second atomization base from the second air inlet hole 312 and the second air outlet hole 341. Compared with the solid or semi-solid second atomization base, the solubility of the fragrance components in the liquid second atomization base is higher, and the fragrance volatilization duration is longer, which is conducive to prolonging the service life of the second atomization base, and there is no solid residue after the fragrance volatilization is completed, which is more environmentally friendly.

[0093] When in use, the airflow flows into the second containing space 310 in the set position through the second air inlet hole 312, and then flows through the liquid storage element 32 through the hollow channel 321, which is conducive to the rapid flow of the airflow through the second containing space 310 and the carrying out of the second aerosol, improves the volatilization efficiency of the second aerosol, and ensures the supply amount of the second aerosol.

[0094] Please refer to Figure 5 In some embodiments, the atomization device 100 further comprises a merging cavity 14, which is in communication with the air outlet 13 and the output end of the atomization assembly 20 and the second containing space 310, and is configured to allow the first aerosol and / or the second aerosol to flow to the air outlet 13.

[0095] The merging cavity 14 communicates the output end of the atomization assembly 20 and the second containing space 310 with the air outlet 13, which can make at least one of the first aerosol and the second aerosol be discharged through the air outlet 13, or make the first aerosol and the second aerosol be mixed and then discharged through the air outlet 13.

[0096] The liquid absorbing cotton (not shown in the figure) can be arranged in the merging cavity 14 to absorb large particle droplets in the first aerosol and the second aerosol, prevent the large particle droplets from being inhaled by the user along with the airflow discharged from the air outlet 13, and ensure the suction taste of the aerosol discharged from the air outlet 13.

[0097] Please refer to Figure 5 In some embodiments, the shell 10 is arranged along the Z-axis direction, i.e. the direction of gravity, the air inlet 12 is arranged at the bottom of the shell 10, and the air outlet 13 is arranged at the top of the shell 10. The mounting cavity 15 (as shown in Figure 7 The second aerosol generating assembly 30 is movably connected in the mounting cavity 15.

[0098] The first accommodating space 111 and the mounting cavity 15 are arranged side by side along the X axis in the shell 10, and the merging cavity 14 is transversely arranged at the upper end of the first accommodating space 111 and the mounting cavity 15. The merging cavity 14 has a first air inlet through hole 141 communicating with the atomization assembly 20 and a second air inlet through hole 142 communicating with the second accommodating space 310, wherein the first air inlet through hole 141 is arranged at the left bottom of the merging cavity 14 and connected with the second through hole 1171, and the second air inlet through hole 142 is arranged at the right bottom of the merging cavity 14 and communicates with the second air outlet hole 341 corresponding to the second accommodating space 310 in the set position. The second through hole 1171 constitutes the output end of the atomization assembly 20, and the second air outlet hole 341 constitutes the output end of the second accommodating space 310.

[0099] Please refer to Figure 5 , Figure 6 The second aerosol generating assembly 30 further comprises a central shaft 33 fixedly connected in the mounting cavity 15 along the Z axis, and a first shaft hole 313 (as shown in Figure 6 ) is arranged through the central axis 311 of the rotating member 31. The rotating member 31 is rotatably connected to the central shaft 33 through the first shaft hole 313. Eight second accommodating spaces 310 are arranged around the first shaft hole 313.

[0100] The second air inlet hole 312 is arranged at the lower end of the rotating member 31 facing the air inlet 12, and the second air outlet hole 341 is arranged at the upper end of the rotating member 31 facing the merging cavity 14. The number of the second air inlet holes 312 and the second air outlet holes 341 is preferably matched with the number of the second accommodating spaces 310, that is, one second air outlet hole 341 and one second air inlet hole 312 are arranged at the upper and lower ends of each second accommodating space 310.

[0101] When in use, the user can manually drive the rotating member 31 to rotate 45° around the central shaft 33 to switch the second accommodating space 310 in gas path communication with the air inlet 12 and the merging cavity 14, so as to change the fragrance of the second aerosol discharged from the air outlet 13 and realize fragrance conversion.

[0102] Please refer to Figure 6 In a specific embodiment, eight first grooves 314 are arranged around the first shaft hole 313 on the rotating member 31, and a notch 3141 is formed at the axial upper end of the first groove 314. The second air inlet hole 312 penetrates the bottom surface of the first groove 314, so that the airflow entering from the air inlet 12 can enter the corresponding first groove 314 through the second air inlet hole 312.

[0103] The second aerosol generating component 30 also includes a first flexible member 34, which is detachably connected to the upper end of the rotating member 31 and closes the slot 3141. The first flexible member 34 and the first groove 314 define a second receiving space 310. A second air outlet 341 is provided through the first flexible member 34 so that the airflow in the second receiving space 310 can be discharged through the corresponding second air outlet 341. The upper end of the central shaft 33 movably abuts against the inner wall surface of the first flexible member 34.

[0104] The liquid storage element 32 can be inserted into the corresponding first groove 314 through the slot 3141.

[0105] In use, if the second atomizing matrix in a certain second containment space 310 is consumed or the fragrance is weakened, the user can remove the first flexible part 34 and add the second atomizing matrix to the corresponding first groove 314 or the liquid storage element 32 through the slot 3141, so as to realize the recycling of the second aerosol generating component 30, reduce the user's operating cost, and extend the service life of the atomizing device 100.

[0106] The first flexible component 34 is made of a flexible material and has a certain degree of elasticity. The flexible material can be selected from silicone, rubber, soft plastic, etc., and this application does not limit it.

[0107] The first flexible member 34 at least partially seals against the top surface of the mounting cavity 15 on the upper end face of the confluence cavity 14, so that the second vent 341 corresponding to the second accommodating space 310 outside the set position can be sealed by the top surface of the mounting cavity 15, so as to prevent the second atomizing matrix in the second accommodating space 310 in the non-use state from evaporating the second aerosol.

[0108] Please see Figure 6 , Figure 7 Correspondingly, the second aerosol generating component 30 also includes a second flexible member 35, which is fixedly connected to the bottom of the mounting cavity 15 and at least partially abuts against the bottom surface of the rotating member 31. The second flexible member 35 is made of a flexible material and has a certain degree of elasticity. The flexible material can be selected from silicone, rubber, soft plastic, etc., and this application does not limit it.

[0109] A second through hole 351 is provided on the second flexible member 35 along the Z-axis. The second through hole 351 is configured to connect the air inlet 12 with the second air inlet 312 corresponding to the second accommodating space 310 in a set position.

[0110] The bottom surface of the installation cavity 15 is provided with a fixed shaft 151 extending along the Z-axis, and the lower end of the central shaft 33 is inserted and fixed on the fixed shaft 151. The second shaft hole 352 is provided at the center of the second flexible piece 35, and the fixed shaft 151 at least partially penetrates the second shaft hole 352 and is fixedly connected with the central shaft 33. The upper end surface of the second flexible piece 35 at least partially seals against the bottom surface of the rotating piece 31, so that the second air inlet hole 312 corresponding to the second containing space 310 in the set position can be closed by the second flexible piece 35, avoiding the second aerosol from the second atomized substrate in the second containing space 310 in the non-use state.

[0111] The first flexible piece 34 cooperates with the top surface of the installation cavity 15 to seal the air outlet end of the second containing space 310 in the set position; and the second flexible piece 35 cooperates with the bottom surface of the rotating piece 31 to seal the air inlet end of the second containing space 310 in the set position, which can avoid the second aerosol from the second containing space 310 in the non-use state, improve the shelf life of the second atomized substrate, and prolong the service life of the second atomized substrate.

[0112] In some embodiments, at least one second containing space 310 is configured as an empty position, wherein the second containing space 310 configured as the empty position does not store the second atomized substrate.

[0113] In actual use, when the user only needs the atomization device 100 to provide the first aerosol, i.e., smoke containing only tobacco components or tobacco substitute components, the empty position second containing space 310 without storing the second atomized substrate can be rotated to the set position, which ensures that the resistance of the atomization device 100 is as small as possible, realizes the pure atomization smoking condition of the atomization device 100, and meets the diversified and personalized use requirements of the user.

[0114] In other embodiments, a one-way valve or a switch can also be provided on the second air inlet through hole 142, and the one-way valve or the switch is configured to close the air outlet end of the second containing space 310 in the set position in the pure atomization smoking condition of the atomization device 100. In addition, a one-way valve or a switch can also be provided on the second through hole 351 to simultaneously close the air inlet end and the air outlet end of the second containing space 310 in the set position in the pure atomization smoking condition of the atomization device 100.

[0115] Compared with the technical solution of setting the at least one second containing space 310 as an idle position, the closure of the second containing space 310 in the set position is realized by a one-way valve or a switch, which to some extent increases the structural complexity and manufacturing cost of the atomization device 100, but is beneficial to increasing the storage of the second atomization substrate of different fragrance smells in the second aerosol generating assembly 30 and increasing the aroma types of the second aerosol.

[0116] As shown in Figure 5 The second containing space 310 set as an idle position is not provided with a liquid storage element 32.

[0117] Please refer to Figure 5 In some embodiments, the atomization device 100 further comprises a first air chamber 16 and a second air chamber 17. The first air chamber 16 is arranged at the lower end of the first containing space 111, and the first air chamber 16 is communicated with the air inlet 12 and the first through hole 1161, and is configured to guide the airflow from the air inlet 12 to the atomization air channel 2221.

[0118] The second air chamber 17 is arranged at the lower end of the mounting cavity 15, and the second air chamber 17 is communicated with the air inlet 12 and the second through hole 351, and is configured to guide the airflow from the air inlet 12 to the second containing space 310 in the set position.

[0119] The atomization device 100 of the present application realizes the air path communication of the atomization air channel 2221, the air inlet 12 and the merging cavity 14 by arranging the first air chamber 16, realizes the air path communication of the second containing space 310 in the set position, the air inlet 12 and the merging cavity 14 by arranging the second air chamber 17, so that part of the airflow entering through the air inlet 12 can be guided to the atomization air channel 2221 under the guidance of the first air chamber 16, and part of the airflow can be guided to the second containing space 310 in the set position under the guidance of the second air chamber 17, and then the first aerosol generated in the atomization air channel 2221 is carried out by the airflow, and the second aerosol volatilized in the second containing space 310 is carried out by the airflow.

[0120] Please refer to Figure 4 In some embodiments, the atomization device 100 further comprises an air inlet adjusting mechanism 40 connected between the air inlet 12 and the first air chamber 16 and the second air chamber 17, and configured to adjust the air inlet amount of the first air chamber 16 and the second air chamber 17.

[0121] The atomization device 100 of the present application adjusts the air inlet amount of the first air chamber 16 and the second air chamber 17 through the air inlet adjusting mechanism 40, so that the user can independently control the airflow size flowing through the atomization air channel 2221 and the second containing space 310 through the air inlet adjusting mechanism 40 to adapt to different working conditions of the atomization device 100.

[0122] For example, when the user only needs the atomization device 100 to provide the first aerosol, the air inlet 12 can be fully distributed to the first air chamber 16 by the air inlet adjusting mechanism 40, at this time the air inlet amount of the second air chamber 17 can be zero, and the first heating element 23 can be configured to be in an energized operating state to heat and generate the first aerosol by heating the first atomization substrate transmitted by the liquid guide 22 to the atomization air channel 2221.

[0123] When the user only needs the atomization device 100 to provide the second aerosol, the air inlet 12 can be fully distributed to the second air chamber 17 by the air inlet adjusting mechanism 40, at this time the air inlet amount of the first air chamber 16 can be zero, and the first heating element 23 can be configured to be in a de-energized and stopped state to prevent the atomization assembly 20 from being burned out and causing the wick to be burned out.

[0124] When the user needs the atomization device 100 to provide a mixed aerosol containing the first aerosol and the second aerosol, the air inlet 12 can be partially distributed to the first air chamber 16 and partially distributed to the second air chamber 17 by the air inlet adjusting mechanism 40, at this time there is air flow into both the first air chamber 16 and the second air chamber 17, and the first heating element 23 can be configured to be in an energized operating state. Further, the first heating element 23 can be configured to operate at different heating powers to adapt to different working conditions of the atomization device 100. For example, in a lung suction working condition, the air flow per puff of the user is relatively larger, and the demand for the mixed aerosol, especially the first aerosol, is larger, at this time the first heating element 23 can be configured to operate at a larger heating power, and the user can distribute more air flow to the first air chamber 16 by the air inlet adjusting mechanism 40 to meet the large air inlet amount requirement of the atomization assembly 20 in the lung suction working condition; for example, in a mouth suction working condition, the air flow per puff of the user is relatively smaller than in the lung suction working condition, and the demand for the mixed aerosol, especially the first aerosol, is smaller, at this time the first heating element 23 can be configured to operate at a smaller heating power, and the user can distribute relatively less air flow to the first air chamber 16 by the air inlet adjusting mechanism 40 to meet the smaller air inlet amount requirement of the atomization assembly 20 in the mouth suction working condition.

[0125] Please refer to Figure 6 、 Figure 7 In some embodiments, the atomization device 100 further comprises a positioning assembly arranged between the rotating member 31 and the inner wall of the mounting cavity 15, configured to limit the rotation of the rotating member 31. The positioning assembly comprises a positioning groove 315 (as shown in Figure 6 ) and a positioning elastic member 152 (as shown in Figure 7The number of positioning grooves 315 is preferably matched with the number of second accommodating spaces 310. The positioning grooves 315 are arranged on the outer wall of the rotating member 31 and correspond to the second accommodating spaces 310 one by one. The positioning elastic members 152 are arranged at least one and fixedly connected to the bottom surface of the mounting cavity 15, configured to be matched and clamped with the positioning grooves 315.

[0126] When the rotating member 31 rotates any one of the second accommodating spaces 310 to a set position, the positioning elastic members 152 are at least partially elastically clamped in the corresponding positioning grooves 315 to limit the rotation of the rotating member 31, realize the positioning of the rotating member 31, avoid the problem that the second accommodating space 310 cannot form a gas path communication with the air inlet 12 and the merging cavity 14 due to insufficient rotation angle or excessive rotation angle of the rotating member 31, and also avoid the problem that the second aerosol generated during use is accidentally switched due to the rotating member 31 being easily rotated by external force interference.

[0127] Please refer to Figure 4 、 Figure 7 In some embodiments, the atomization device 100 further comprises a window 18 formed on the shell 10 and communicating the mounting cavity 15 with the external space of the shell 10. The rotating member 31 is at least partially exposed to the window 18, so as to facilitate the user to rotate the rotating member 31 through the window 18, and facilitate the user to use.

[0128] The above application of specific examples to the technical solutions of the present application is only used to help understand the content of the present application and does not limit the present application.
