Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an aerosol generation device. Background Technology

[0002] An aerosol generating device is a device that includes an atomizer for atomizing a liquid formulation to generate an aerosol. An exemplary aerosol generating device exists, including a housing and an atomizer at least partially disposed within the housing. The atomizer is configured to be replaceable, requiring the replacement of the atomizer to first obtain a new atomizer, then remove the original atomizer, and finally assemble the new atomizer into the housing.

Both the first and second atomizers are configured to move relative to the housing, thereby switching between a hidden state (covered by the housing) and an exposed state (at least partially protruding from the housing). Both the first and second atomizers include a mouthpiece, which is housed inside the housing in the hidden state and exposed outside the housing in the exposed state to provide inhalation for the user. The transmission mechanism is linked to the first and second atomizers, and when one of the first and second atomizers changes from an exposed state to a hidden state, the transmission mechanism can drive the other to move, causing the other to change from a hidden state to an exposed state, thereby selectively providing inhalation for the user. Therefore, when it is necessary to change the atomizer, there is no need to remove the atomizer and assemble a new one. Simply by changing the mouthpiece of one atomizer from being exposed outside the housing to being housed inside the housing, the mouthpiece of the other atomizer can be automatically changed from being housed inside the housing to being exposed outside the housing. Thus, the atomizer can be changed with a simple operation. Attached Figure Description

[0047] Please refer to Figure 1 This application provides an embodiment of an aerosol generating device 100, which includes a housing 1 and at least two atomizers 2 that are movable relative to the housing 1.

[0048] In some embodiments, the atomizer 2 includes an atomizing core 26, which, when powered, atomizes an aerosol generation matrix to generate an aerosol.

[0049] As an example, the aerosol generating matrix includes a liquid matrix, and the atomizing core 26 includes a liquid-absorbing element and a heating element disposed on the liquid-absorbing element. The liquid-absorbing element can be a porous body for guiding the liquid matrix into the atomization range of the heating element. The heating element is used to heat the atomized liquid matrix, thereby generating a sol.

[0050] As an example, the aerosol generating matrix includes a liquid matrix, and the atomizing core 26 includes an ultrasonic element capable of generating ultrasonic waves, which can use ultrasonic waves to atomize the liquid matrix to form an aerosol.

[0051] Of course, the atomizing core 26 may also include other elements that enable the liquid matrix to be atomized into an aerosol.

[0052] In some embodiments, the atomizer 2 includes a storage chamber 21 for storing an aerosol generation matrix. When the storage chamber 21 is used to store a liquid matrix, the storage chamber 21 is in fluid communication with the atomizing core 26, so that the liquid matrix stored in the storage chamber 21 can flow to the atomizing core 26 and be atomized by the atomizing core 26.

[0053] The aerosol generating matrix stored in the storage chamber 21 of different atomizers 2 can be the same, so that different atomizers 2 can produce aerosols with the same flavor or aroma. The aerosol generating matrix stored in the storage chamber 21 of different atomizers 2 can be different, so that different atomizers 2 can produce aerosols with different flavors or aromas.

[0054] In some embodiments, the aerosol generating matrix includes a liquid matrix, which is liquid at room temperature. The liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco flavor components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but are not limited to these. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. The vitamin mixture may be a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited to these. The atomizer 2 can be used in various fields, such as medical and electronic aerosol atomization.

[0055] In some embodiments, the atomizer 2 further includes an air guide tube 22, which is in fluid communication with the atomizing core 26. The air guide tube 22 can guide the aerosol generated by the atomizing aerosol matrix generated by the atomizing core 26 to the corresponding atomizer 2.

[0056] At least a portion of the atomizing core 26 may be disposed in the air delivery tube 22. Alternatively, the atomizer 2 may also include a compartment in which the atomizing core 26 is disposed. The compartment is connected to the storage chamber 21 via a liquid channel, allowing the liquid matrix in the storage chamber 21 to be transferred to the atomizing core 26. The compartment is in fluid communication with the air delivery tube 22, allowing the aerosol formed in the compartment to be discharged through the air delivery tube 22.

[0057] In some embodiments, the atomizer 2 further includes a liquid reservoir element (not shown), which has a large number of pores and is capable of adsorbing a large amount of liquid matrix. The liquid reservoir element is disposed in a storage cavity, and at least partially of the liquid matrix stored in the storage cavity is retained in the liquid reservoir element, thereby preventing the liquid matrix from leaking out of the storage cavity. The liquid reservoir element includes, but is not limited to, one of the following materials: cotton fiber, polypropylene fiber, polyester fiber, nylon fiber, porous ceramic material, polymer fiber, or various combinations of the above materials.

[0058] The atomizer 2 also includes a mouthpiece 23 with an air inlet 231. The air inlet 231 is used to discharge the aerosol generated by the atomizer 2. When the mouthpiece 23 is exposed outside the housing 1, it can be held in the mouth by the user. When held in the mouth by the user, the air inlet 231 is oriented towards the user's mouth, so that the user can inhale the aerosol generated by the atomizer 2 by sucking the mouthpiece 23.

[0059] The atomizer 2 is configured to move relative to the housing 1. By moving the atomizer 2 relative to the housing, it can switch between a hidden state, where it is covered by the housing 1, and an exposed state, where it protrudes at least partially from the housing 1. When the atomizer 2 is in the exposed state, its mouthpiece 23 is exposed outside the housing, allowing the user to inhale the aerosol generated by the atomizer 2, thus putting the atomizer 2 into use. When the atomizer 2 is in the hidden state, its mouthpiece 23 is housed inside the housing 1, making it inconvenient or impossible for the user to hold in their lips, thus putting the atomizer 2 into a non-use state.

[0060] For ease of description, two of the multiple atomizers 2 are defined as the first atomizer 24 and the second atomizer 25.

[0061] Thus, the first atomizer 24 is movable relative to the housing 1, and the first atomizer 24 can switch between an exposed state and a concealed state. Specifically, the first atomizer 24 is configured to move relative to the housing 1 between a first position and a second position. When in the first position, the first atomizer 24 is in an exposed state, with its mouthpiece 23 protruding from the housing 1 and exposed outside the housing 1. When in the second position, the first atomizer 24 is in a concealed state, with at least a portion of its mouthpiece 23 covered by the housing 1 and thus housed inside the housing 1. Furthermore, when the first atomizer 24 moves from the first position to the second position, the first atomizer 24 changes from an exposed state to a concealed state; conversely, when it moves from the first position to the second position, the first atomizer 24 changes from a concealed state to an exposed state.

[0062] Similarly, the second atomizer 25 is movable relative to the housing 1, and the second atomizer 25 23 can switch between an exposed state and a concealed state. Specifically, the second atomizer 25 is configured to move relative to the housing 1 between a third position and a fourth position. In the third position, the second atomizer 25 is in an exposed state, with its mouthpiece 23 protruding from the housing 1 and exposed outside the housing 1. In the fourth position, the second atomizer 25 is in a concealed state, with at least a portion of its mouthpiece 23 covered by the housing 1 and thus housed inside the housing 1. Furthermore, when the second atomizer 25 moves from the third position to the fourth position, the second atomizer 25 changes from an exposed state to a concealed state; conversely, when it moves from the third position to the fourth position, the second atomizer 25 changes from a concealed state to an exposed state.

[0063] In some embodiments, reference may be made to Figure 2The aerosol generating device 100 also includes a transmission mechanism 3. The transmission mechanism 3 is linked to at least two atomizers 2, so that the transmission mechanism 3 will respond to any movement or change of any atomizer 2. Furthermore, during the operation of the transmission mechanism 3, at least two atomizers 2 move simultaneously relative to the housing 1.

[0064] Furthermore, the transmission mechanism 3 is configured to drive at least one atomizer 2 to move from a hidden state to an exposed state when any one atomizer 2 moves from an exposed state to a hidden state, thereby changing the atomizer 2 in the exposed state. Thus, under the action of the transmission mechanism 3, at the same time as one atomizer 2 changes from an exposed state to a hidden state, at least one atomizer 2 automatically changes from a hidden state to an exposed state.

[0065] More specifically, the transmission mechanism 23 is configured to drive the other atomizer 24 to move when the other atomizer 25 changes from an exposed state to a hidden state, thereby providing the user with inhalation in either the sleeve 23 of the first atomizer 24 or the mouthpiece of the second atomizer 25.

[0066] In some embodiments, the atomizer 2 is configured to move along a straight trajectory between an exposed state and a concealed state to shorten the travel distance of the atomizer 2 between the exposed state and the concealed state, which helps to simplify the structure of the aerosol generating device 100 and reduce the volume of the aerosol generating device 100.

[0067] Furthermore, the straight-line trajectories of at least two atomizers 2 are parallel to each other, thereby preventing the at least two atomizers 2 from colliding when they move simultaneously relative to the housing 1. Even further, the straight-line trajectories of all atomizers 2 are parallel to each other.

[0068] More specifically, both the first atomizer 24 and the second atomizer 25 are configured to move along a straight trajectory when they change between a hidden state and an exposed state, and the straight trajectory of the first atomizer 24 and the straight trajectory of the second atomizer 25 are parallel to each other.

[0069] More specifically, the first atomizer 24 can move along a first straight line trajectory between a first position and a second position, and the second atomizer 25 can move along a second straight line trajectory between a third position and a fourth position. The first straight line trajectory can be parallel to the second straight line trajectory.

[0070] In some embodiments, when the first atomizer 24 is in an exposed state, it can be operated to change to a concealed state. More specifically, when the first atomizer 24 is in an exposed state, its mouthpiece 23 is exposed outside the housing 1, allowing the mouthpiece 23 to be operated to move the first atomizer 24 relative to the housing 1. The first atomizer 24 can be driven to move from an exposed state to a concealed state by operating it. Furthermore, while driving the first atomizer 24 to move by operating it, the linkage between the first atomizer 24 and the transmission mechanism 3 can cause the transmission mechanism 3 to operate, thereby driving the second atomizer 25 to move from a concealed state to an exposed state.

[0071] In some embodiments, when the second atomizer 25 is in an exposed state, the second atomizer 25 can be operated to change to a hidden state. Furthermore, while driving the second atomizer 25 to move by operating the second atomizer 25, the transmission mechanism 3 can be operated through the linkage between the second atomizer 25 and the transmission mechanism 3 to drive the first atomizer 24 to move from a hidden state to an exposed state.

[0072] Alternatively, not shown, the transmission mechanism includes an operating part exposed outside the housing. The user can drive the transmission mechanism through the operating part to make the first atomizer and the second atomizer move simultaneously, thereby changing the atomizer 2 in the exposed state.

[0073] In some embodiments, at least one atomizer 2 of the plurality of atomizers 2 is in an exposed state, and at least one atomizer 2 is in a concealed state. There are limitations on all atomizers 2 being simultaneously exposed and all atomizers 2 being simultaneously concealed. For example, the mouthpiece 23 of only one of the first atomizer 24 and the second atomizer 25 may be exposed, while the mouthpiece 23 of the other may be concealed.

[0074] In some embodiments, the transmission mechanism 3 is configured to cause the first atomizer 24 and the second atomizer 25 to move synchronously in opposite directions; or, refer to Figure 1 and Figure 2 It is located at the same end of the housing 1 adjacent to the first position of the first atomizer 24 and the third position of the second atomizer 24. Thus, after changing the atomizer 2 which is in the exposed state, the user can continue to use the atomizer 100 and inhale the atomizer generated by other atomizers 2 without having to tilt, turn or invert the atomizer 100.

[0075] In some embodiments (not shown), a first atomizer is provided with a first rack, the first rack including a plurality of first protrusions or a plurality of first grooves spaced apart from each other, and the plurality of first protrusions or a plurality of first grooves are arranged in a straight line. A second atomizer is provided with a second rack, the second rack including a plurality of second protrusions or a plurality of second grooves spaced apart from each other, and the plurality of second protrusions or a plurality of second grooves are arranged in a straight line.

[0076] The transmission mechanism includes gears that mesh with a first rack and a second rack. Thus, when the gears rotate, the first atomizer and the second atomizer can move simultaneously. Furthermore, the gears can be driven to rotate by operating either the first or second atomizer, thereby driving the other atomizer to move. Alternatively, the rotation of the gears can drive the first and second atomizers to move simultaneously in different directions.

[0077] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes a power supply assembly 4, a first receiving part 5 movable relative to the housing 1, and a first power supply electrode (not shown) disposed on the first receiving part 5, the first power supply electrode being electrically connected to the power supply assembly 4.

[0078] Power supply component 4 includes a power source, which may include any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery. Power supply component 4 may also include a circuit board electrically connected to the power source, and at least one controller disposed on the circuit board for controlling the electrical power output of the power source. In some embodiments, the controller includes at least one microprocessor or microcontroller. The microprocessor or microcontroller may include a logic gate array, or may include a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor.

[0079] The aerosol generating apparatus 100 may further include a first conductive wire (not shown) for electrically connecting the first power supply electrode and the power supply assembly 4. One end of the first conductive wire may be soldered to the first power supply electrode, and the other end may be electrically connected to the power supply assembly 4. The first conductive wire may have a considerable length, thereby enabling the first receiving portion 5 to maintain a stable electrical connection with the first power supply electrode and the power supply assembly 4 when moving relative to the housing 1. The first conductive wire may include a spring wire, thereby being retractable.

[0080] The first power supply electrode may include a metal sheet, a metal spring, or a metal spring needle. The first power supply electrode may be held on the first receiving part 5 by means of insert injection molding or assembly, or the first power supply electrode may be a conductive layer formed on the surface or surface layer of the first receiving part 5 by means of coating, deposition, ion implantation, particle sputtering, etc.

[0081] The first atomizer 24 also includes a first electrode 241. The first atomizer 24 is connected to the first receiving part 5. When the first atomizer 24 and the first receiving part 5 are connected, the first electrode 241 is electrically connected to the first power supply electrode, and then the first atomizer 24 is electrically connected to the power supply assembly 4.

[0082] The first atomizer 24 is connected to the first receiving part 5 so that the first atomizer 24 and the first receiving part can keep synchronized and move in the same direction.

[0083] The first receiving part 5 or the first atomizer 24 cooperates with the transmission mechanism 3, so that the first receiving part 5 or the first atomizer 24 can be driven by the transmission mechanism 3.

[0084] For example, a first rack 51 is provided on the first receiving part 5 or the first atomizer 24, and the transmission mechanism 3 includes a gear 31, which meshes with the first rack 51. Thus, when the gear 31 rotates, the first receiving part 5 and the first atomizer 24 can be driven to move relative to the housing 1 through the first rack 51, or when the first atomizer 24 and the first receiving part 5 move relative to the housing 1, the first rack 51 can drive the gear 31 to rotate.

[0085] The first electrode 241 has at least two electrodes, and the first power supply component may have at least two electrodes. The first electrode 241 is electrically connected to the atomizing core 26 of the first atomizer 24. The atomizing core 26 of the first atomizer 24 can form a power supply circuit between the first electrode 241 and the corresponding first power supply component and the power supply component 4.

[0086] Preferably, the first rack 51 is disposed on the first receiving portion 5, and the first atomizer 24 is removably connected to the first receiving portion 5, and the first electrode 241 is detachably electrically connected to the first power supply electrode. This allows the first atomizer 24 to be replaced.

[0087] Furthermore, the first atomizer 24 is configured to move from an exposed state to a concealed state along a first direction, and from a concealed state to an exposed state along a second direction. When the first atomizer 24 is in the exposed state, it can be operated to remove it from the first receiving portion 5 along the second direction. For example, when the first atomizer 24 is in the exposed state, the mouthpiece 23 of the first atomizer 24 can be operated to remove the first atomizer 24 from the first receiving portion 5 along the second direction. The first direction is opposite to the second direction.

[0088] Furthermore, the first receiving part 5 includes a receiving cavity in which a portion of the first atomizer 24 is removably disposed.

[0089] In some embodiments, reference may be made to Figure 2 and Figure 3The aerosol generating device 100 also includes a second receiving part 6 movable relative to the housing 1 and a second power supply electrode disposed on the second receiving part 6, the second power supply electrode being electrically connected to the power supply assembly.

[0090] The aerosol generating apparatus 100 may further include a second conductor (not shown) for electrically connecting the second power supply electrode and the power supply assembly 4. One end of the second conductor may be soldered to the second power supply electrode, and the other end may be electrically connected to the power supply assembly 4. The second conductor may have a considerable length, thereby enabling the second receiving portion 6 to maintain a stable electrical connection with the second power supply electrode and the power supply assembly 4 when moving relative to the housing 1. The second conductor 4 may include a spring wire, thereby being retractable.

[0091] The second power supply electrode may have the same structural features as the first power supply electrode, and the second power supply electrode may be made of the same material or by the same method as the first power supply electrode.

[0092] The second atomizer 25 also includes a second electrode 251. The second atomizer 25 is connected to the second receiving part 6. When the second atomizer 25 and the second receiving part 6 are connected, the second electrode 251 is electrically connected to the second power supply electrode, and then the second atomizer 25 is electrically connected to the power supply assembly 4.

[0093] The second atomizer 25 is connected to the second receiving part 6 so that the second atomizer 25 and the second receiving part 6 can move synchronously and in the same direction.

[0094] The second receiving part 6 or the second atomizer 25 cooperates with the transmission mechanism 3, so that the second receiving part 6 or the second atomizer 25 can be driven by the transmission mechanism 3.

[0095] For example, a second rack 62 is provided on the second receiving part 6 or the second atomizer 25, and the transmission mechanism 3 includes a gear 31, which meshes with the second rack 62. Thus, when the gear 31 rotates, the second receiving part 6 and the second atomizer 25 can be driven to move relative to the housing 1 via the second rack 62, or when the second atomizer 25 and the second receiving part 6 move relative to the housing 1, the gear 31 can be driven to rotate via the second rack 62.

[0096] Preferably, gear 31 is disposed between the first receiving part 5 and the second receiving part 6, or gear 31 is disposed between the first atomizer 24 and the second atomizer 25.

[0097] The second electrode 251 has at least two electrodes, and the second power supply component may have at least two electrodes. The second electrode 251 is electrically connected to the atomizing core 26 of the second atomizer 25. The atomizing core 26 of the second atomizer 25 can form a power supply circuit with the power supply component 4 through the second electrode 251 and the corresponding second power supply component.

[0098] Preferably, the second rack 61 is disposed on the second receiving portion 6, and the second atomizer 25 is removably connected to the second receiving portion 6, and the second electrode 251 is detachably electrically connected to the second power supply electrode. This allows the second atomizer 25 to be replaced.

[0099] Furthermore, the second atomizer 25 is configured to move from an exposed state to a concealed state along a first direction, and to move from a concealed state to an exposed state along a second direction. When the second atomizer 25 is in the exposed state, the second atomizer 25 can be operated to remove it from the second receiving portion 6 along the second direction. For example, when the second atomizer 25 is in the exposed state, the mouthpiece 23 of the second atomizer 25 can be operated to remove the second atomizer 25 from the second receiving portion 6 along the second direction.

[0100] The first receiving part 5 and the second receiving part 6 can have the same structural features.

[0101] In such Figure 3 In the embodiment shown, the first rack 51 and the second rack 61 are located on opposite sides of the gear 31, and the direction in which the first rack 51 extends is parallel to the direction in which the second rack 61 extends, so that the first atomizer 24 and the second atomizer 25 can perform synchronous linear motion in opposite directions.

[0102] In some embodiments, reference may be made to Figure 1 The housing 1 is provided with a first opening 11. When the first atomizer 24 is in an exposed state, it protrudes from the first opening 11 out of the housing 1 and is exposed outside the housing 1 so that it can be held in the mouth by the user. When the first atomizer 24 is in a hidden state, at least part of the mouthpiece 23 of the first atomizer 24 is retracted into the housing 1 and covered by the housing 1 and then contained inside the housing 1.

[0103] The housing 1 may also be provided with a second opening 12 independent of the first opening 11. When the second atomizer 25 is in the exposed state, it protrudes from the housing 1 through the second opening 12 and is exposed outside the housing 1, so that it can be held in the mouth by the user. When the second atomizer 25 is in the hidden state, at least part of the mouthpiece 23 of the second atomizer 25 is retracted into the housing 1 and blocked by the housing 1 and then contained inside the housing 1.

[0104] Preferably, the first opening 11 and the second opening 12 are located at the same end of the housing 1.

[0105] Furthermore, not shown, the aerosol generating device also includes a cover plate, one end of which is rotatably connected to the housing to block the opening corresponding to any atomizer when it is switched to a hidden state, so as to prevent solid debris from the outside from entering the atomizer in the hidden state.

[0106] For example, the cover is connected to the housing via a hinge. Preferably, the hinge is located between the first opening and the second opening, and the cover is configured to flip between the first opening and the second opening, such that when the first atomizer is in a hidden state, the cover can cover the first opening, and when the second atomizer is in a hidden state, the cover can flip to cover the second opening. Furthermore, during the movement of the first atomizer from a hidden state to an exposed state, the first atomizer can drive the cover to flip, so that the cover automatically flips from covering the first opening to covering the second opening, and vice versa.

[0107] In some embodiments, reference may be made to Figure 1 and Figure 2 The housing 1 is provided with a first air inlet 13 and a second air inlet 14 that communicate with the outside air. The first air inlet 13 is configured to be connected to the first atomizer 24 when the first atomizer 24 is exposed, and to be disconnected from the first atomizer 24 when the first atomizer 24 is hidden. The second air inlet 14 is configured to be connected to the second atomizer 25 when the second atomizer 25 is exposed, and to be disconnected from the second atomizer 25 when the second atomizer 25 is hidden.

[0108] Therefore, when one of the first atomizer 24 and the second atomizer 25 is in an exposed state and the other is in a hidden state, only the atomizer 2 in the first atomizer 24 and the second atomizer 25 in the exposed state is in fluid communication with the outside air through the corresponding air inlet.

[0109] Furthermore, the first receiving part 5 is also provided with a first vent 52 that is in communication with the first atomizer 24. When the first atomizer 24 is in the hidden state, the air passage between the first vent 52 and the first air inlet 13 is disconnected; see reference Figure 2 When the first atomizer 24 is exposed, the air passage between the first vent 52 and the first air inlet 13 is connected.

[0110] Furthermore, the second receiving part 6 is also provided with a second vent 62 that communicates with the second atomizer 25. (See reference...) Figure 2 When the second atomizer 25 is in a hidden state, the air passage between the second vent 62 and the second air inlet 14 is disconnected; when the second atomizer 25 is in an exposed state, the air passage between the second vent 62 and the second air inlet 14 is open.

[0111] In some embodiments, the first atomizer 24 is configured to block the first air inlet 13 when it is in a concealed state. For example, when the first atomizer 24 is in a concealed state, the first atomizer 24 covers the first air inlet 13 on the inside of the housing 1, so that the first air inlet 13 is blocked from entering the first vent 51.

[0112] In some embodiments, reference may be made to Figure 2 The first receiving part 5 is configured to block the first air inlet 13 when the first atomizer 24 is in a hidden state. For example, when the first atomizer 24 is in a hidden state, the first receiving part 5 covers the first air inlet 13 on the inside of the housing 1, so that the first air inlet 13 is blocked from entering the first vent 51.

[0113] In some embodiments, the second atomizer 25 is configured to block the second air inlet 14 when it is in a hidden state.

[0114] In some embodiments, reference may be made to Figure 2 The second receiving part 6 is configured to block the second air inlet 14 when the second atomizer 25 is in a hidden state.

[0115] In some embodiments, the power supply component 4 is configured to provide electrical power only to the atomizer 2 in the first atomizer 24 and the second atomizer 25 that is exposed when the atomizer 100 is aspirated, such that only one of the first atomizer 24 and the second atomizer 25 generates aerosol.

[0116] For example, the aerosol generating device 100 further includes a first airflow detector (not shown) in airflow communication with the inlet 231 of the first atomizer 24 and a second airflow detector (not shown) in airflow communication with the inlet 231 of the second atomizer 25. The first airflow detector is used to detect whether the first atomizer 24 is being aspirated based on airflow changes. Specifically, when the first atomizer 24 is being aspirated, the airflow velocity, air pressure, or airflow direction at the inlet 231, air guide tube 22, and atomizing core 26 of the first atomizer 24 will change. When the change exceeds a threshold, the first airflow detector generates a first detection signal to indicate that the first atomizer 24 has been aspirated. Similarly, the second airflow detector is used to detect whether the second atomizer 25 is being aspirated based on airflow changes. The first and second airflow detectors can be airflow detectors of the same specification, for example, both can be microphones. The power supply component 4 is configured to provide electrical power to the atomizer 2 being aspirated.

[0117] Therefore, when only the atomizer 2 in the first atomizer 24 and the second atomizer 25 is in an exposed state and is in fluid communication with the outside air through the corresponding air inlet, when drawing in the atomizer 2 in the exposed state, it is possible to prevent the power supply component 4 from also providing electrical power to the atomizer 2 in the hidden state.

[0118] Furthermore, a first airflow detector is disposed on the first receiving part 5, so that the first airflow detector can move with the first receiving part 5.

[0119] The second airflow detector can also be installed on the second receiving part 6, so that the second airflow detector can move with the second receiving part 6.

[0120] In some embodiments, the ventilation area of ​​the second air inlet 14 is larger than the air intake area of ​​the first air inlet 13, and / or the number of second air inlets 14 is greater than the number of first air inlets 13. Therefore, the suction resistance of drawing from the second atomizer 25 is less than the suction resistance of drawing from the first atomizer 24.

[0121] Furthermore, when the first atomizer 24 is the exposed atomizer 2, the power supply component 4 provides a first power to the first atomizer 24; when the second atomizer 25 is the exposed atomizer 2, the power supply component 4 provides a second power to the second atomizer 25, wherein the first power is less than or equal to the second power. Therefore, the amount or concentration of aerosol generated when the first atomizer 24 is the exposed atomizer 2 is different from the amount or concentration of aerosol generated when the second atomizer 25 is the exposed atomizer 2, thus providing a different sensory experience to the user after changing the exposed atomizer 2.

[0122] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
