For the atomization device with DTL (Direct To Lung, lung suction) -MTL (Mouth To Lung, mouth suction) dual-mode switching function, the atomization assembly has different requirements for the air intake amount in different working modes, and therefore the air intake adjusting mechanism needs to be matched to realize the air intake amount adjustment in different working modes.

[0003] In related designs, the adjusting piece of the air intake adjusting mechanism is generally set to gradually increase or decrease the air intake amount in the process of moving from the starting position to the terminal position.

When the adjusting member is in the second position, the stop portion at least partially blocks the air inlet through hole. When the adjusting member is in the third position, the second opening communicates the air inlet through hole and the external space of the housing with a maximum air passage area. The second position is between the first position and the third position. During movement of the adjusting member from the first position to the second position, the area of the first opening in communication with the air inlet through hole gradually decreases. During movement of the adjusting member from the second position to the third position, the area of the second opening in communication with the air inlet through hole gradually increases.

[0006] In some embodiments, the air inlet member is provided with an air inlet groove, and the air inlet groove is provided with an air inlet through hole and an air inlet blind hole. The air inlet groove communicates with the air inlet end of the atomization assembly through the air inlet through hole. The opening area of the first opening is greater than the opening area of the second opening. When the adjusting member is in the first position, the first opening corresponds to the air inlet through hole in a projection of the air inlet member. When the adjusting member is in the third position, the second opening corresponds to the air inlet blind hole in the projection of the air inlet member.

[0007] In some embodiments, one side of the air inlet member facing the adjusting member is provided with a sealing portion surrounding the periphery of the air inlet groove. The stop portion is sealingly abutted on the sealing portion.

[0008] In some embodiments, the air inlet adjusting mechanism further comprises: an air inlet adjusting port, which is arranged at one end of the housing and corresponds to the air inlet groove, and is configured to communicate the air inlet groove and an external space of the housing. The adjusting member is at least partially movably clamped between the air inlet adjusting port and the air inlet groove.

[0011] In some embodiments, the shell is internally provided with a liquid storage cavity for storing an atomized substrate, the atomizing assembly comprises a liquid guide part in liquid path communication with the liquid storage cavity, the liquid guide part is provided with an atomizing air channel, an air inlet end of the atomizing air channel being in communication with the air inlet through hole of the air inlet part; a heating part is accommodated in the atomizing air channel and at least partially attached to the liquid guide part; the shell is provided with an air outlet hole in communication with an air outlet end of the atomizing air channel.

[0012] In some embodiments, the liquid storage cavity is provided with a liquid storage part in liquid path communication with the liquid guide part, the liquid storage part is provided with a gas exchange channel configured to be in communication with an external space of the liquid storage cavity.

[0013] In some embodiments, the atomizing device further comprises an air inlet channel in communication with the air inlet through hole and an air inlet end of the atomizing assembly; an air flow sensor comprising a negative pressure surface responsive to a suction negative pressure for controlling the heating of the heating part, the negative pressure surface being in air flow communication with the air inlet channel; wherein the air inlet channel and the negative pressure surface are both parallel to the height direction of the atomizing device.

[0014] In some embodiments, the atomizing device further comprises a regulation button electrically connected to the heating part for switching the working mode of the heating part; and / or a display module for displaying the running state of the atomizing device.

[0015] The atomizing device provided in the present application comprises a shell, an atomizing assembly and an air inlet adjusting mechanism, the air inlet adjusting mechanism comprises an air inlet part in communication with an air inlet end of the atomizing assembly through an air inlet through hole and an adjusting member moving relative to the shell, the adjusting member comprises a stop part, a first opening and a second opening penetrating through the stop part.

[0016] When the adjusting member is in the first position, the first opening communicates the air inlet hole with the outside space of the shell with its maximum air passage area, so that the air outside the atomization device can enter the air inlet hole through the first opening and flow to the atomization assembly through the air inlet member, realizing the maximum air intake in one working mode of mouth suction or lung suction. When the adjusting member is in the second position, the stop portion blocks at least part of the air inlet hole, at which time the air intake of the air inlet hole is relatively minimum, and in the case that the stop portion completely blocks the air inlet hole, the air inlet hole does not intake air, suitable for blocking the air flow interaction between the atomization device and the outside space in the shutdown state, preventing mis-triggering. When the adjusting member is in the third position, the second opening communicates the air inlet hole with the outside space of the shell with its maximum air passage area, so that the air outside the atomization device can enter the air inlet hole through the second opening and flow to the atomization assembly through the air inlet member, realizing the maximum air intake in the other working mode of mouth suction or lung suction.

[0017] The atomization device of the present application only needs to drive the adjusting member to move between the first position and the third position during use, so that the air intake of the atomization assembly can be adjusted from large to small and from small to large in the two working modes of mouth suction and lung suction, and the function of blocking the air flow interaction between the atomization device and the outside space in the shutdown state can be realized at the second position between mode switching, and by presetting the positions corresponding to the maximum air intake in different modes, it is beneficial to quickly and accurately adjust to the best air intake preset in the current working mode of the atomization device after mode switching, and the air intake adjusting operation is more convenient, efficient and accurate.

[0037] The technical solutions of the present application will be described in further detail below with specific embodiments in conjunction with the 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 of the 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.

[0038] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0039] In order to facilitate the understanding of 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.

[0040] Please refer to Figures 1 to 11 In some embodiments of the present application, an atomization device 100 is provided, which comprises a shell 1, the inside of the shell 1 is provided with an atomization assembly 2 (as shown in Figure 8 ), one end of the shell 1 is provided with an air inlet adjusting mechanism 3 (as shown in Figure 2 ), the air inlet adjusting mechanism 3 comprises: an air inlet piece 31 and an adjusting piece 32, the air inlet piece 31 is provided with an air inlet through hole 313 which is in communication with the air inlet end of the atomization assembly 2.

[0041] Please refer to Figure 4The adjusting member 32 is configured to move between a first position, a second position and a third position relative to the housing 1, and comprises a stop portion 321, a first opening 322 and a second opening 323 passing through the stop portion 321. The first opening 322 can have an opening area different from that of the second opening 323.

[0042] Referring to Figure 5 When the adjusting member 32 is in the first position, the first opening 322 communicates the air inlet hole 313 with the external space of the housing 1 with its maximum ventilation area. In the present embodiment, the first position corresponds to the right side of the X-axis in the figure.

[0043] Referring to Figure 6 When the adjusting member 32 is in the second position, the stop portion 321 at least partially blocks the air inlet hole 313. In the present embodiment, the second position corresponds to the middle of the X-axis in the figure, wherein the stop portion 321 is configured to completely block the air inlet hole 313, so that when the adjusting member 32 is in the second position, the air inlet of the atomization assembly 2 is completely blocked. In other embodiments, the stop portion 321 can also be configured to partially block the air inlet hole 313 when the adjusting member 32 is in the second position, so that a small amount of airflow can still enter the atomization assembly 2 through the air inlet hole 313.

[0044] Referring to Figure 7 When the adjusting member 32 is in the third position, the second opening 323 communicates the air inlet hole 313 with the external space of the housing 1 with its maximum ventilation area. In the present embodiment, the third position corresponds to the left side of the X-axis in the figure.

[0045] It should be noted that the maximum ventilation area of the first opening 322 refers to the maximum effective area through which the first opening 322 and the air inlet hole 313 can communicate. The maximum ventilation area of the second opening 323 refers to the maximum effective area through which the second opening 323 and the air inlet hole 313 can communicate.

[0046] The second position is between the first position and the third position, and the adjusting member 32 passes through the second position when moving from the first position to the third position or when moving from the third position to the first position.

[0047] When the adjusting member 32 moves from the first position to the second position, the area through which the first opening 322 and the air inlet hole 313 communicate gradually decreases; when the adjusting member 32 moves from the second position to the third position, the area through which the second opening 323 and the air inlet hole 313 communicate gradually increases.

[0048] Similarly, the area of the second opening 323 communicating with the air inlet hole gradually decreases when the adjusting member 32 moves from the third position to the second position; and the area of the first opening 322 communicating with the air inlet hole 313 gradually increases when the adjusting member 32 moves from the second position to the first position.

[0049] When the adjusting member 32 is in the first position, the first opening 322 communicates the air inlet hole 313 with the external space of the shell 1 at the maximum air passage area, so that the air outside the atomization device 100 can enter the air inlet hole via the first opening 322 and flow to the atomization assembly 2 through the air inlet member 31, realizing the maximum air intake in one working mode of mouth suction or lung suction.

[0050] When the adjusting member 32 is in the second position, the stop portion 321 blocks the air inlet member 31, so that the external air cannot enter the atomization assembly 2, which is suitable for blocking the air flow interaction between the atomization device 100 and the external space in the stop state to prevent accidental triggering.

[0051] When the adjusting member 32 is in the third position, the second opening 323 communicates the air inlet hole 313 with the external space of the shell 1 at the maximum air passage area, so that the air outside the atomization device 100 can enter the air inlet hole 313 via the second opening 323 and flow to the atomization assembly 2 through the air inlet member 31, realizing the maximum air intake in the other working mode of mouth suction or lung suction.

[0052] The atomization device 100 of the present application can realize the adjustment of the air intake of the atomization assembly 2 from large to small and from small to large in the two working modes of mouth suction and lung suction by only driving the adjusting member 32 to move between the first position and the third position, and can realize the function of blocking the air flow interaction between the atomization device 100 and the external space in the stop state at the second position between the mode switching, and can realize the actual adjustment requirement of the air intake from small to large after the mode switching without moving the adjusting member 32 in the reverse direction, by presetting the positions corresponding to the maximum air intake in different modes, which is conducive to quickly and accurately adjusting to the best air intake preset in the current working mode of the atomization device after the mode switching, and the air intake adjustment operation is more convenient, efficient and accurate.

[0053] In the DTL lung suction mode, the atomization assembly 2 has a relatively larger air intake requirement; in the MTL mouth suction mode, the atomization assembly 2 has a relatively smaller air intake requirement. Therefore, the first opening 322 and the second opening 323 of the adjusting piece 32 can be provided with different opening areas, and one of the first opening 322 and the second opening 323 with a relatively larger opening area is configured to be used for air intake in the lung suction mode, and one of the first opening 322 and the second opening 323 with a relatively smaller opening area is configured to be used for air intake in the mouth suction mode. The following examples take the first opening 322 with a larger opening area than the second opening 323 as an example for illustration.

[0054] Please refer to Figure 3 、 Figures 8 to 9 In some embodiments, the air intake piece 31 comprises a base body 311, and an air intake groove 312 is arranged on a surface of the base body 311 facing the adjusting piece 32. The bottom of the air intake groove 312 is provided with the air intake through hole 313 and the air intake blind hole 3121, and the air intake groove 312 communicates with the air intake end of the atomization assembly 2 through the air intake through hole 313.

[0055] In a specific embodiment, the air intake through hole 313 and the air intake blind hole 3121 are arranged in parallel along the slotting direction of the air intake groove 312, wherein the air intake through hole 313 is located on the left side of the bottom surface of the air intake groove 312, the air intake blind hole 3121 is located on the right side of the bottom surface of the air intake groove 312, and the air intake through hole 313 penetrates the air intake groove 312 and the base body 311 along the Z-axis.

[0056] As shown in Figure 6 , when the adjusting piece 32 is in the second position, the stop portion 321 closes the air intake groove 312, and the first opening 322 and the second opening 323 are respectively adjacent to the left and right ends of the air intake groove 312.

[0057] As shown in FIG. 5, when the adjusting piece 32 is in the first position, the projection of the first opening 322 on the air intake piece 31 corresponds to the air intake through hole 313, and at this time, the second opening 323 is outside the right end of the air intake groove 312. As shown in FIG. 7, when the adjusting piece 32 is in the third position, the projection of the second opening 323 on the air intake piece 31 corresponds to the air intake blind hole 3121, and at this time, the first opening 322 is outside the left end of the air intake groove 312.

[0058] The air inlet groove 312 of the air inlet piece 31 is in communication with the air inlet end of the atomization assembly 2 through the air inlet through hole 313, and the air inlet groove 312 is concave from the side of the base body 311 facing the adjusting piece 32. When the adjusting piece 32 is in the second position, the stop portion 321 blocks the air inlet groove 312, preventing external air from entering the air inlet end of the atomization assembly 2 through the air inlet groove 312 and the air inlet through hole 313 of the air inlet piece 31. This is suitable for blocking the air flow interaction between the atomization device 100 and the external space in the shutdown state, which can prevent the atomization device 100 from leaking liquid when not in use, and can also avoid the problem of external objects entering the air inlet piece 31 through the first opening 322 or the second opening 323 on the adjusting piece 32, thereby causing the air inlet through hole 313 to be blocked, thereby protecting the air inlet through hole 313.

[0059] When the adjusting piece 32 is in the first position, the projection of the first opening 322 on the air inlet piece 31 corresponds to the air inlet through hole 313, and the stop portion 321 blocks the slot area of the air inlet groove 312 except the area corresponding to the air inlet through hole 313. At this time, the first opening 322 directly communicates the air inlet through hole 313 and the external space of the shell 1 with the largest air passage area, realizing the maximum air intake in the lung suction working mode. In addition, the first opening 322 corresponds to the air inlet through hole 313 at this time, and the external air can directly enter without obstruction, which is more efficient in terms of air intake to meet the demand for rapid air intake in the lung suction working mode.

[0060] When the adjusting piece 32 is in the third position, the projection of the second opening 323 on the air inlet piece 31 corresponds to the air inlet blind hole 3121, and the stop portion 321 blocks the slot area of the air inlet groove 312 except the area corresponding to the second opening 323. At this time, the second opening 323 tortuously communicates the air inlet through hole 313 and the external space of the shell 1 with the largest air passage area, realizing the maximum air intake in the mouth suction working mode. In addition, the second opening 323 and the air inlet through hole 313 are approximately "Z" type staggered communication, and when the external air enters through the second opening 323, it will be at least stopped by the air inlet blind hole 3121, which can limit the air intake flow to a certain extent to meet the relatively smaller air intake demand in the mouth suction working mode.

[0061] In some embodiments, the opening area of the air inlet through hole 313 is not less than the opening area of the first opening 322, so that when the adjusting member 32 is in the first position, the air outside the shell 1 directly flows to the air inlet through hole 313 through the first opening 322, and the maximum air intake amount can enter the air inlet member 31 and the atomization assembly 2, and the air intake efficiency is the highest, at this time, the atomization assembly 2 is configured to operate in the lung suction working mode. When the adjusting member 32 is in the third position, the air outside the shell 1 can flow to the air inlet through hole 313 through the second opening 323, and a relatively smaller air intake amount can enter the air inlet member 31 and the atomization assembly 2, and the air flow is at least partially blocked by the bottom surface of the air inlet groove 312 during the air intake process, and the air intake amount is relatively smaller, at this time, the atomization assembly 2 is configured to operate in the oral suction working mode.

[0062] Please refer to Figures 5 to 7 In some embodiments, the opening area of the first opening 322 is greater than the opening area of the second opening 323, and the opening size of the first opening 322 matches the opening size of the air inlet through hole 313.

[0063] When the adjusting member 32 is in the first position, the projection of the first opening 322 on the air inlet member 31 corresponds to the air inlet through hole 313, and the second opening 323 is outside the right end of the air inlet groove 312, the air outside the shell 1 enters the air inlet groove 312 through the first opening 322 and flows to the atomization assembly 2 through the air inlet through hole 313, at this time, the atomization assembly 2 is configured to operate in the lung suction working mode, and the atomization assembly 2 has the maximum air intake amount in this working mode. During the movement of the adjusting member 32 from the first position to the second position, the area of the first opening 322 communicating with the air inlet groove 312 gradually decreases; during the movement of the adjusting member 32 from the second position to the first position, the area of the first opening 322 communicating with the air inlet groove 312 gradually increases. In this way, the variable adjustment of the air intake amount of the atomization assembly 2 by the adjusting member 32 in the lung suction working mode is realized.

[0064] When the adjusting member 32 is in the third position, the projection of the second opening 323 on the air inlet member 31 corresponds to the air inlet blind hole 3121, and the first opening 322 is outside the left end of the air inlet groove 312, the air outside the shell 1 enters the air inlet groove 312 through the second opening 323 and flows to the atomization assembly 2 through the air inlet through hole 313, at this time, the atomization assembly 2 is configured to operate in the oral suction working mode, and the atomization assembly 2 has the maximum air intake amount in this working mode. During the movement of the adjusting member 32 from the third position to the second position, the area of the second opening 323 communicating with the air inlet groove 312 gradually decreases; during the movement of the adjusting member 32 from the second position to the third position, the area of the second opening 323 communicating with the air inlet groove 312 gradually increases. In this way, the variable adjustment of the air intake amount of the atomization assembly 2 by the adjusting member 32 in the oral suction working mode is realized.

[0065] Please refer toFigure 3 、 Figures 5 to 7 In some embodiments, the air inlet member 31 is provided with a sealing portion 314 on the side facing the adjusting member 32, the sealing portion 314 being arranged outside the periphery of the air inlet groove 312, and the stop portion 321 is sealingly abutted against the sealing portion 314.

[0066] The stop portion 321 of the adjusting member 32 is sealingly abutted against the sealing portion 314 of the air inlet member 31, so that the sealing portion 314 seals the air inlet groove 312 and the adjusting member 32, preventing the air entering through the first opening 322 or the second opening 323 from leaking out of the gap between the adjusting member 32 and the air inlet member 31, and ensuring that all the air entering through the corresponding opening of the adjusting member 32 flows to the atomization assembly 2 through the air inlet groove 312 and the air inlet through hole 313, thereby avoiding air leakage and ensuring the atomization effect.

[0067] In some embodiments, the air inlet member 31 is made of a flexible material, and the base body 311 and the sealing portion 314 are integrally formed of the flexible material. The flexible material can be selected from silica gel material, rubber material, soft plastic material, etc., which are not limited in the present application. The flexible material can achieve good sealing between the sealing portion 314 of the air inlet member 31 and the stop portion 321 of the adjusting member 32, and prevent the air entering through the first opening 322 or the second opening 323 from leaking out of the gap between the air inlet groove 312 and the stop portion 321.

[0068] Please refer to Figure 2 In some embodiments, the air inlet adjusting mechanism 3 further comprises an air inlet adjusting opening 33, the air inlet adjusting opening 33 being arranged at one end of the housing 1 and corresponding to the air inlet groove 312, the air inlet adjusting opening 33 being configured to communicate the air inlet groove 312 and the external space of the housing 1. The adjusting member 32 is at least partially movably clamped between the air inlet adjusting opening 33 and the air inlet groove 312.

[0069] In combination with Figure 2 and Figure 6 When the adjusting member 32 is in the second position, the stop portion 321 closes the air inlet groove 312 on the side facing the air inlet member 31, the stop portion 321 closes the air inlet adjusting opening 33 on the side away from the air inlet member 31, and the first opening 322 and the second opening 323 are both closed by the inner wall of the housing 1, so that the air outside the housing 1 cannot enter the air inlet member 31 and the atomization assembly 2 through the adjusting member 32.

[0070] Please refer to Figure 2 and Figure 5When the adjusting member 32 is in the first position, the first opening 322 corresponds to between the air inlet through hole 313 and the left end of the air inlet adjusting port 33, and the second opening 323 is closed by the inner wall of the shell 1. At this time, the air outside the shell 1 flows to the atomization assembly 2 in sequence through the air inlet adjusting port 33, the first opening 322, the air inlet groove 312 and the air inlet through hole 313.

[0071] In combination Figure 2 and Figure 7 When the adjusting member 32 is in the third position, the second opening 323 corresponds to between the air inlet blind hole 3121 and the right end of the air inlet adjusting port 33, and the first opening 322 is closed by the inner wall of the shell 1. At this time, the air outside the shell 1 flows to the atomization assembly 2 in sequence through the air inlet adjusting port 33, the second opening 323, the air inlet groove 312 and the air inlet through hole 313.

[0072] Please refer to Figure 8 and Figure 9 In an embodiment, the shell 1 includes an outer shell 11, an inner shell assembly, and a bottom cover 12. The outer shell 11 has an inner cavity, and one end of the shell 1 along the Z-axis direction is provided with a mouthpiece 111 which communicates with the inner cavity thereof, and the other end along the Z-axis direction is provided with a first mounting port 112 which communicates with the inner cavity thereof. The inner shell assembly is fixedly installed in the inner cavity of the outer shell 11 through the first mounting port 112, and the inner shell assembly communicates the mouthpiece 111 and the first mounting port 112. The bottom cover 12 is fixedly encapsulated on the first mounting port 112, and the air inlet adjusting port 33 is provided through the bottom cover 12.

[0073] The atomization assembly 2 is arranged in the inner shell assembly, for heating an atomization substrate to atomization and generating an aerosol. The air inlet member 31 is arranged at one end of the inner shell assembly towards the bottom cover 12, and the air inlet through hole 313 communicates with the air inlet end of the atomization assembly 2 through the inner shell assembly. The adjusting member 32 is movably connected between the air inlet member 31 and the bottom cover 12, and the adjusting member 32 is freely adjustable between the first position and the third position compared to the shell 1.

[0074] The air inlet end of the atomization assembly 2 communicates with the air inlet adjusting port 33 through the air inlet through hole 313, the air inlet groove 312, the first opening 322 or the second opening 323, and the air outlet end of the atomization assembly 2 communicates with the mouthpiece 111.

[0075] When in use, the user inhales from the mouthpiece 111 to generate a negative pressure inside the shell 1, and the air outside the shell 1 flows to the air inlet end of the atomization assembly 2 through the air inlet adjusting port 33 on the bottom cover 12, the first opening 322 or the second opening 323 on the adjusting member 32, the air inlet groove 312 and the air inlet through hole 313 on the air inlet member 31, so as to bring out the aerosol generated by the atomization assembly 2 by using the airflow, and make the aerosol discharged through the mouthpiece 111 for the user to smoke.

[0076] The air inlet member 31 in the embodiment is integrally formed by using silica gel material, and is elastically clamped between the inner shell assembly and the adjusting member 32. The air inlet member 31 can realize good sealing between the movable member and the inner shell assembly by using its own elasticity, so as to ensure that the air entering through the first opening 322 or the second opening 323 of the adjusting member 32 can all flow to the atomization assembly 2 through the air inlet groove 312 and the air inlet through hole 313, avoiding the problem of air leakage. In addition, the elastic air inlet member 31 can provide a certain resistance for the movement of the adjusting member 32, so as to position the adjusting member 32 and keep the position of the adjusting member 32, avoiding the problem that after the air inlet amount is adjusted to an appropriate size, the position of the adjusting member 32 is changed by external force interference, affecting the normal air inlet of the atomization assembly 2, and ensuring the reliability of adjusting the air inlet amount of the atomization device 100 by the air inlet adjusting mechanism 3.

[0077] Please refer to Figure 2 and Figure 4 In some embodiments, the adjusting member 32 further comprises a knob 324 fixedly connected to the stopper 321, and the knob 324 at least partially extends into the air inlet adjusting port 33 along the Z axis, and the first opening 322 and the second opening 323 are respectively located on two sides of the knob 324.

[0078] When the adjusting member 32 is in the first position, the knob 324 is stopped in the right end inner wall of the air inlet adjusting port 33 to limit the limit of the movement of the adjusting member 32 to the right side along the air inlet adjusting port; when the adjusting member 32 is in the third position, the knob 324 is stopped in the left end inner wall of the air inlet adjusting port 33 to limit the limit of the movement of the adjusting member 32 to the left side along the air inlet adjusting port.

[0079] In use, the user can drive the adjusting member 32 to reciprocate within the opening range of the air intake adjusting port 33 by the dialing part 324, and when the dialing part 324 is stopped on any one of the inner walls at the left and right ends of the air intake adjusting port 33, the adjusting member 32 can be quickly moved to the first position or the second position, so that the atomization assembly 2 has the maximum air intake amount in the corresponding working mode, which plays an indicating role of the maximum air intake amount in the corresponding working condition, and the user does not need to manually gradually control the air intake amount, but only needs to move the dialing part 324 to the end of the path trajectory of the air intake adjusting port 33 to achieve the optimal air intake amount in the corresponding working condition, which is convenient for the user to adjust the air intake amount of the atomization assembly 2 and more convenient to use.

[0080] Please refer to Figure 3 , Figures 5 to 7 In some embodiments, the air intake member 31 further comprises a first abutting part 315 arranged on one side of the base body 311 facing the adjusting member 32, and the first abutting part 315 is provided with at least two parts extending along the moving path direction of the adjusting member 32 and distributed on both sides of the air intake groove 312. The height of the first abutting part 315 is consistent with the height of the sealing part 314, and during the reciprocating movement of the adjusting member 32 between the first position and the third position, the side of the stop part 321 facing the air intake member 31 at least partially abuts the first abutting part 315 at all times, so as to prevent the end of the adjusting member 32 away from the air intake groove 312 from being warped upward in the Z-axis direction after the position of the adjusting member 32 changes, and to avoid air leakage between the stop part 321 of the adjusting member 32 and the periphery of the air intake groove 312 of the air intake member 31.

[0081] Please refer to Figures 4 to 7 In some embodiments, the adjusting member 32 further comprises a second abutting part 325 arranged on one side of the stop part 321 facing the bottom cover 12, and the second abutting part 325 is provided with at least two parts extending along the moving path direction of the adjusting member 32 and distributed on both sides of the first opening 322 and the second opening 323. During the reciprocating movement of the adjusting member 32 between the first position and the third position, the side of the bottom cover 12 facing the adjusting member 32 at least partially abuts the second abutting part 325 at all times, so as to prevent the end of the adjusting member 32 away from the air intake groove 312 from being warped, shaken and the like in the Z-axis direction after the position of the adjusting member 32 changes, and to avoid air leakage between the stop part 321 of the adjusting member 32 and the periphery of the air intake groove 312 of the air intake member 31.

[0082] The design of the first abutting portion 315 and the second abutting portion 325 can stably hold the adjusting member between the air inlet member 31 and the bottom cover 12, avoid the problems such as warping and shaking during the position change of the adjusting member 32, and ensure the movement stability of the adjusting member 32. On the other hand, the first abutting portion 315 and the second abutting portion 325 cooperate with the sealing portion 314 to provide certain damping for the movement of the adjusting member 32 on the opposite two surfaces, realize the limiting of the position change of the adjusting member 32, and ensure the precise adjustment of the air inlet adjusting mechanism 3 on the air inlet amount of the atomization device 100.

[0083] The first abutting portion 315 and the second abutting portion 325 can be made of flexible materials, which can be selected from silica gel materials, rubber materials, soft plastic materials, etc., and the present application does not limit this. The flexible materials can realize good sealing between the first abutting portion 315 and the second abutting portion 325 and the stop portion 321, and provide appropriate friction damping for the movement of the adjusting member 32, thereby limiting the adjusting member 32.

[0084] Please refer to Figures 2 to 7 In some embodiments, the adjusting member 32 moves along an arc-shaped path between the first position, the second position and the third position, and the center axis of the arc-shaped path is coaxially arranged with the central axis 10 of the shell 1 (as shown in Figure 8 .

[0085] The arrangement of the adjusting member 32 moving along the arc-shaped path can reduce the straight line length of the air inlet adjusting port 33 and the air inlet groove 312, reduce the space occupation of the bottom cover and the air inlet member 31, and be beneficial to the miniaturization and intensification design of the atomization device 100. Compared with the straight line path, the first opening 322 and the second opening 323 have a relatively larger air inlet area adjustable interval when the adjusting member 32 moves along the arc-shaped path, which can realize more precise air inlet amount adjustment.

[0086] Correspondingly, the air inlet adjusting port 33, the first opening 322 and the second opening 323 of the adjusting member 32 are arranged as arc-shaped openings matched with the curvature of the arc-shaped movement path of the adjusting member, the stop portion 321 of the adjusting member 32 is arranged as an arc-shaped plate structure matched with the curvature of the arc-shaped movement path of the adjusting member, and the overall size of the stop portion 321 is larger than the opening size of the air inlet adjusting port 33 to prevent the adjusting member 32 from being pulled out of the air inlet adjusting port 33.

[0087] Please refer to Figure 8 and Figure 10 In some embodiments, the shell 1 is provided with a liquid storage cavity 18 (as shown in Figure 8The atomization assembly 2 comprises a liquid guide 21 and a heating element 22. The liquid guide 21 is in liquid communication with the liquid storage cavity 18 and is configured to absorb the atomization substrate stored in the liquid storage cavity 18 and deliver the atomization substrate to the heating element 22. The heating element 22 is configured to heat the atomization substrate delivered by the liquid guide 21 to an atomized state and generate aerosol.

[0088] The liquid guide 21 is provided with an atomization air passage 2111, and the air inlet end of the atomization air passage 2111 is in communication with the air inlet through hole 313 of the air inlet member 31. The heating element 22 is accommodated in the atomization air passage 2111 and at least partially adheres to the liquid guide 21.

[0089] Correspondingly, the housing 1 is provided with an air outlet hole 1111 in communication with the air outlet end of the atomization air passage 2111, and the air outlet hole 1111 is formed in the end of the mouthpiece portion 111.

[0090] In use, the liquid guide 21 delivers the atomization substrate absorbed from the liquid storage cavity 18 to the heating element 22 accommodated in the atomization air passage 2111, and the heating element 22 generates heat under the driving of electricity to heat the atomization substrate to an atomized state and generate aerosol. At the same time, external air entering through the air inlet adjusting mechanism 3 enters the atomization air passage 2111 from the air inlet end to carry out the generated aerosol under the action of fluid and discharge outwardly from the air outlet end of the atomization air passage 2111 and the air outlet hole 1111 of the mouthpiece portion 111 for the user to inhale.

[0091] Please refer to Figure 10 In an embodiment, the liquid guide 21 comprises a main body portion 211 and an extension portion 212. The main body portion 211 is provided in a columnar structure extending along the Z-axis, and the atomization air passage 2111 penetrates the main body portion 211 in the axial direction. The extension portion 212 is provided in a strip-shaped structure or a block-shaped structure extending in the radial direction of the main body portion 211 and can extend into the liquid storage cavity 18 in the radial direction to facilitate the liquid guide 21 to directly absorb the atomization substrate from the liquid storage cavity 18.

[0092] Please refer to Figure 8 In some embodiments, the inner housing assembly comprises a first inner housing 13, a connecting middle frame 14, and an atomization air guide tube 15.

[0093] The atomization assembly 2 further comprises a seat body 23 and a wick tube 24. The first inner housing 13 has an inner cavity, and the first inner housing 13 is provided with a sealing member 16 at the upper end in the Z-axis direction, which communicates the inner cavity of the first inner housing 13 with the air outlet hole 1111, and is provided with a second mounting opening 131 at the lower end in the Z-axis direction, which communicates the inner cavity of the first inner housing 13.

[0094] The sealing member 16 is provided with a first air guide hole 161 along the central axis 10 of the shell 1. The atomization air guide pipe 15 is a tubular structure with both ends open, arranged in the inner cavity of the first inner shell 13 along the central axis 10 of the shell 1, and the upper end of the atomization air guide pipe 15 facing away from the second mounting port 131 is fixedly connected to the first air guide hole 161 and communicates with the air outlet hole 1111 through the first air guide hole 161.

[0095] The connecting middle frame 14 is fixedly connected to the second mounting port 131 towards the upper end of the first inner shell 13, and the seat body 23 is fixedly clamped between the connecting middle frame 14 and the first inner shell 13 and closes the second mounting port 131.

[0096] The seat body 23 is provided with a fixed part 231 extending along the central axis 10 of the shell 1 towards the upper end surface of the atomization air guide pipe 15, and the fixed part 231 is provided with an air passage hole 2311 penetrating the fixed part 231 and the seat body 23 in the axial direction.

[0097] The core pipe 24 is a tubular structure with both ends open, the lower end is fixedly inserted into the fixed part 231, and the upper end is fixedly inserted into the atomization air guide pipe 15 towards the lower end of the second mounting port 131. The air passage hole 2311 communicates the outer space of the bottom surface of the connecting middle frame 14 facing away from the first inner shell 13 with the core pipe 24 and the atomization air guide pipe 15.

[0098] The seat body 23, the core pipe 24, the atomization air guide pipe 15, the sealing member 16, and the first inner shell 13 define the liquid storage cavity 18.

[0099] Please refer to Figure 10 , at least one liquid inlet is provided on the inner wall of the core pipe 24, and the liquid inlet communicates the liquid storage cavity 18 with the inner cavity of the core pipe 24. The main part 211 of the liquid guide member 21 is accommodated in the core pipe 24, and the extension part 212 of the liquid guide member 21 extends from one of the liquid inlets into the liquid storage cavity 18, so that the atomization substrate in the liquid storage cavity 18 can be adsorbed onto the main part 211 of the liquid guide member 21 through the extension part 212 and each liquid inlet respectively, and then transmitted to the heating element 22 accommodated in the atomization air guide pipe 2111 by the main part 211.

[0100] The liquid inlet includes at least one first liquid inlet 241 penetrating the pipe wall of the core pipe 24 at one end, which is used to communicate the liquid storage cavity 18 with the inner wall of the core pipe 24, and when the liquid guide member 21 is assembled on the core pipe 24, the extension part 212 is loaded from the pipe wall of the core pipe 24 at one end and extends into the liquid storage cavity 18 through the first liquid inlet 241.

[0101] Please refer to Figure 10In some embodiments, the liquid inlet further comprises at least one second liquid inlet 242 extending through the wall of the core tube 24 in the radial direction, and the opening shape of the second liquid inlet 242 can be set as a regular shape such as a circle, an ellipse, a polygon, etc., or an irregular shape.

[0102] When in use, a part of the atomized substrate in the liquid storage cavity 18 is adsorbed to the main body 211 through the extension 212 extending into the first liquid inlet 241, and a part is directly adsorbed to the main body 211 through the second liquid inlet 242, so that the liquid guiding efficiency is higher.

[0103] Please refer to Figure 8 In some embodiments, a liquid absorbing cotton 19 is arranged between the sealing member 16 and the suction nozzle 111, and a via hole is arranged through the liquid absorbing cotton 19 in the axial direction and communicates the first air guiding hole 161 and the air outlet hole 1111. The liquid absorbing cotton 19 is used to adsorb liquid particles in the aerosol, so as to avoid the liquid particles from being inhaled into the mouth of the user and affecting the suction taste of the aerosol. In addition, the liquid absorbing cotton 19 can also play a role in cooling the aerosol, so as to prevent the temperature of the discharged aerosol from being too high and causing the user to be scalded.

[0104] After the air outside the shell 1 enters the inner shell assembly through the air inlet adjusting mechanism 3, it flows to the atomization air duct 2111 through the air passage hole 2311 and the core tube 24, the aerosol generated by the heating element 22 heating the atomized substrate enters the atomization air duct 15 under the action of the airflow, and finally is discharged from the first air guiding hole 161 of the sealing member 16, the via hole of the liquid absorbing cotton 19 and the air outlet hole 1111 of the suction nozzle 111 for the user to inhale.

[0105] The inner shell assembly and the atomization assembly 2 of the aerosolizing device 100 of the present application can be quickly assembled in an axial installation manner, and the number of components is small and the manufacturing cost is low, so that the production and manufacturing of the aerosolizing device 100 are facilitated.

[0106] Please refer to Figure 8 and Figure 10 In some embodiments, a liquid storage member 25 is arranged in the liquid storage cavity 18, and the liquid storage member 25 and the liquid guiding member 21 form a liquid path communication.

[0107] The atomized substrate in the liquid storage cavity 18 is adsorbed on the liquid storage member 25 and then transmitted to the liquid guiding member 21 through the liquid storage member 25, which significantly reduces the risk of liquid leakage of the liquid storage cavity 18 compared with the way that the atomized substrate in the liquid storage cavity 18 directly enters the liquid guiding member 21 through the liquid inlet, and improves the user experience.

[0108] Please refer to Figure 10 A ventilation passage 251 is arranged on the liquid storage member 25, and the ventilation passage 251 is configured to communicate with the outside space of the liquid storage cavity 18.

[0109] The heating element operates at a relatively larger power in the lung suction condition, and the heat radiated outward is larger. Because the atomized substrate is adsorbed on the liquid storage element, and the liquid storage element is in liquid path communication with the liquid guide element, part of the atomized substrate adsorbed on the liquid storage element will be atomized due to the heat radiation of the heating element during use, and an aerosol is formed inside the liquid storage cavity. When the atomization device continuously operates at a large power condition, more aerosol accumulates inside the liquid storage cavity, and the pressure inside the liquid storage cavity is larger, so the atomization device is prone to failure due to the excessively high pressure in the liquid storage cavity, and in severe cases, an explosion accident may occur, which has a high safety risk.

[0110] The atomization device 100 provided in the present application is provided with the ventilation channel 251 on the liquid storage element 25, which provides a pressure relief path for the atomized atomized substrate on the liquid storage element 25, can timely discharge the aerosol from the liquid storage cavity 18, prevent the high pressure risk caused by the accumulation of the aerosol in the liquid storage cavity 18, and ensure the use safety of the atomization device 100.

[0111] Please refer to Figure 10 In a specific embodiment, two ventilation channels 251 are arranged on the left and right side walls of the liquid storage element 25 along the Z-axis. Correspondingly, the sealing element 16 is provided with a plurality of ventilation holes (not marked), which are arranged on the inner wall of the first air guide hole 161 and communicate the liquid storage cavity 18 with the outside space.

[0112] During use, part of the atomized substrate on the liquid storage element 15 is atomized by the heat radiated from the heating element 22, and the generated aerosol can be discharged from the first air guide hole 161 through the ventilation channel 251 and the ventilation hole, mixed with the airflow discharged from the atomization air guide pipe, and then discharged from the air outlet hole 1111 for the user to smoke.

[0113] Please refer to Figure 8 and Figure 11 In some embodiments, the atomization device 100 further comprises a control assembly 4 electrically connected with the heating element 22, for controlling the operation of the heating element 22 and switching the working mode of the heating element 22.

[0114] The working mode of the heating element 22 needs to be adjusted correspondingly according to the air inlet amount of the atomization assembly 2, so as to prevent the problems of burnt wick caused by the operation of the heating element 22 at a large power when the air inlet amount is insufficient, and the problems of low aerosol concentration and poor taste caused by the operation of the heating element 22 at a small power when the air inlet amount is too large.

[0115] Please refer to Figure 8 In some embodiments, the atomization device further comprises an air inlet channel 173 and an airflow sensor 9, and the air inlet channel 173 communicates the air inlet hole 313 with the air inlet end of the atomization assembly 2.

[0116] The airflow sensor 9 comprises a negative pressure surface 91 for controlling the heating of the heating element 22 in response to the suction negative pressure, and the negative pressure surface 91 is in airflow communication with the air inlet channel 173.

[0117] In this embodiment, the height direction of the atomization device 100 is the Z-axis direction, and the air inlet channel 173 and the negative pressure surface 91 of the airflow sensor 9 are both arranged in the vertical direction.

[0118] The airflow sensor 9 is electrically connected to the control assembly 4, detects the airflow change in the air inlet channel 173 through the negative pressure surface 91, and sends an airflow change detection signal to the control assembly 4, and the control assembly 4 controls the operation of the heating element 22 according to the received airflow change detection signal.

[0119] For example, when the airflow sensor 9 detects that there is no airflow passing through the air inlet channel 173, at this time the atomization assembly 2 does not intake air, and the control assembly 4 can be configured to control the heating element to be powered off according to the airflow change detection signal in this state, so as to prevent the heating element 22 from being dry-burned; when the airflow sensor 9 detects that there is airflow passing through the air inlet channel 173, at this time the atomization assembly 2 intakes air, and the control assembly 4 can be configured to control the heating element to heat according to the airflow change detection signal in this state, so as to make the atomization device 100 enter the working state. In this way, the atomization device 100 can be automatically started and stopped according to the airflow change in the air inlet channel 173, without the need to configure physical start and stop keys for the atomization device, which is convenient for user operation and use.

[0120] When the airflow sensor 9 detects that the airflow in the air inlet channel 173 is enhanced, at this time the air intake amount of the atomization assembly 2 is increased, and the control assembly 4 can be configured to correspondingly increase the heating power of the heating element according to the airflow change detection signal in this state, so as to prevent the problem of poor atomization effect caused by insufficient heating of the heating element 22; when the airflow sensor 9 detects that the airflow in the air inlet channel 173 is weakened, at this time the air intake amount of the atomization assembly 2 is reduced, and the control assembly 4 can be configured to correspondingly reduce the heating power of the heating element according to the airflow change detection signal in this state, so as to prevent the problem of burnt core caused by excessive heating of the heating element 22.

[0121] In the related art, the negative pressure surface 91 of the airflow sensor 9 is generally arranged transversely to ensure the accuracy of the detection result, but the transversely arranged negative pressure surface 91 is easy to drip and leak the atomized substrate, which affects the normal use of the atomization device.

[0122] The atomization device 100 provided in the application sets the negative pressure surface 91 of the airflow sensor 9 in the height direction of the atomization device 100, that is, the vertical direction, which can prevent the atomization substrate from leaking onto the negative pressure surface 91 of the airflow sensor 9, and since the airflow of the atomization assembly 2 is large under the lung suction condition, even if the negative pressure surface 91 is vertically set, it will not substantially affect the accuracy of the detection result of the airflow sensor 9.

[0123] Please refer to Figure 8 and Figure 11 In some embodiments, the control assembly 4 comprises a PCB control board 41 and a control button 42, the PCB control board 41 is integrated with a control module 411, the control module 411 is electrically connected with the airflow sensor 9, the control button 42 and the heating element 22 respectively, and is used for controlling the operation of the heating element 22. The control button 42 is configured to send a control signal to the control module 411 after being pulled, pressed or touched, and the control module 411 switches the working mode of the heating element 22 according to the received control signal.

[0124] In some embodiments, the control button 42 of the control assembly 4 can be set as a switch controlled by a pull rod, and the pull rod can be set to be linked with the adjusting element 32 to drive the pull rod to move synchronously when the position of the adjusting element 32 changes, thereby changing the control signal output by the control button 42, to realize the automatic switching of the working mode of the heating element 22 while adjusting the air intake.

[0125] Please refer to Figure 2 and Figure 8 In some embodiments, the control button 42 of the control assembly 4 can also be set as a switch controlled by pressing or touching and independently controlled compared with the air intake adjusting mechanism 3, so that the user can select the appropriate working mode of the heating element 22 according to the actual air intake of the atomization assembly 2 after the position of the adjusting element 32 changes by pressing or touching the control button 42, which is better in self-controlling degree and higher in flexibility of mode switching control, and is more in line with the personal use habits of the user.

[0126] Please refer to Figure 8 and Figure 9 In an embodiment, the inner shell assembly further comprises a second inner shell 17, the second inner shell 17 has an inner cavity, and the upper end of the second inner shell 17 in the Z-axis direction is provided with a third mounting port 171 communicating with the inner cavity thereof. The air inlet channel 173 is arranged in the inner cavity of the second inner shell 17 along the Z-axis direction, and the lower end of the air inlet channel 173 penetrates through the bottom surface of the second inner shell 17 and forms a communication port 1731 (as shown in Figure 9 ) communicating with the air inlet through hole 313.

[0127] The connecting middle frame 14 is fixedly connected to the third mounting port 171 towards the lower end of the second inner shell 17, and the inner cavity of the second inner shell 17 is communicated with the air vent 2311, so that the air entering the second inner shell 17 through the communication port 1731 can enter the atomization air channel 2111 in the core tube 24 through the air vent 2311.

[0128] The connecting middle frame 14 fixedly connects the first inner shell 13 and the second inner shell 17, so that the components of the inner shell assembly can be assembled in the Z-axis direction, the structure is simple and stable, the assembly is convenient, the internal density of the atomization device 100 is higher, the automatic assembly is facilitated, and the production cost can be reduced.

[0129] Please refer to Figure 11 In some embodiments, the atomization device 100 further comprises a display module 5 and a power supply module 6. The display module 5 is electrically connected with the control assembly 4 to display the running state of the atomization device 100. The power supply module 6 is electrically connected with the display module 5, the control assembly 4, the airflow sensor 9 and the heating element 22 respectively to supply power for the atomization device 100.

[0130] The power supply module 6 comprises a battery 61, which can be a rechargeable battery or a disposable dry battery, and the present application does not make any limitation in this regard.

[0131] The display module 5 comprises a display screen 51 electrically connected with the control module 411 through a display circuit. The display screen 51 can be an LED display screen, an OLED display screen or a liquid crystal display screen. The display screen 51 can be configured to display the working mode of the atomization device 100 (such as MTL mouth suction mode, DTL lung suction mode), the heating power and on / off state of the heating element 22, the light special effect under different working conditions, the battery 61 power information, the liquid amount information of the atomization substrate in the liquid storage cavity 18 and the like.
