Description

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 including an atomizer used to atomize liquid formulations to generate aerosols. However, due to the size limitation of the atomizer, the amount of liquid formulation that can be stored in the atomizer is limited. An exemplary aerosol generating device exists, including multiple atomizers and multiple microphones. The microphones are fluidly connected to the multiple atomizers through multiple independent detection airways, each corresponding to one of the atomizers. The microphones are used to determine whether a corresponding atomizer is being aspirated based on changes in airflow in the detection airways, and when a corresponding atomizer is detected being aspirated, the microphones control a power supply to provide electrical power to that atomizer, causing it to generate aerosols. Furthermore, by selectively activating one of the detection airways, or the inlet or outlet airway of one of the atomizers, one atomizer can be designated as the working atomizer, while the others are designated as non-working atomizers.

[0003] However, when the aerosol generator is turned on, both the microphone corresponding to the working atomizer and the microphone corresponding to the non-working atomizer are in a power-consuming on state, resulting in high power consumption of the aerosol generator, which is not conducive to extending the battery life of the aerosol generator.

[0066] Please refer to Figure 1 and Figure 2 This application provides an embodiment of an aerosol generating device 100, which includes a power supply 1, a control component 3, and a plurality of atomizers 2. The control component 3 is used to selectively switch the power supply 1 to provide electrical power to one or at least two of the plurality of atomizers 2, thereby causing the atomizer 2 that is provided with electrical power to atomize the aerosol generating matrix to generate aerosol.

[0067] In some embodiments, the aerosol-generating matrix includes nicotine. Nicotine may include nicotine or nicotine salts. Nicotine has a neurostimulatory effect and is used to provide the user with the pleasure of inhalation. The aerosol generated by the aerosol-generating matrix contains nicotine.

[0068] In some embodiments, the aerosol generating matrix includes flavorings used to stimulate the user's sense of smell to provide aroma or to stimulate the user's sense of taste to adjust flavor.

[0069] Flavoring agents may include cooling agents. Cooling agents make the aerosol refreshing and cool, which helps to enhance the throat-soothing effect. Cooling agents include, but are not limited to, at least one of: N,2,3-trimethyl-2-isopropylbutyramide (WS-23), menthol, peppermint oil, and N-ethyl-p-menthyl-3-carboxamide (WS-3).

[0070] Flavoring agents may include sweeteners. Sweeteners enhance the sweetness of the aerosol, improving its flavor. Sweeteners include, but are not limited to, N-[N-(3,3-dimethylbutyl)]-L-α-aspartic-L-phenylalanine 1-methyl ester (also known as neotame). Sweeteners may also include, but are not limited to, one or more of the following: sucralose, steviol glycosides, neotame, acesulfame potassium, aspartame, glycyrrhizin, sodium saccharin, cyclamate, and monk fruit extract.

[0071] Flavoring agents may include tobacco extracts. The main components of tobacco extracts include tobacco cellulose, tobacco leaf protein, and other substances with tobacco aroma, but do not include nicotine or similar substances. Tobacco extracts can enhance the similarity between the smoke and traditional cigarette smoke, giving the aerosol a traditional cigarette flavor.

[0072] Flavoring agents may include flavorings. Flavorings can reduce the irritation caused by tobacco extracts. For example, flavorings may include at least one of 2-acetylpyrazine, ethyl maltol, and methyl dihydrojasmonate. Flavorings may also include throat-soothing ingredients. Throat-soothing ingredients include, but are not limited to, at least one of eugenol, clove leaf oil, clove bud oil, Peruvian balsam oil, fenugreek tincture, star anise oil, vanilla bean tincture, tea polyphenols, lemon oil, and propylene glycol.

[0073] In some embodiments, the aerosol generating matrix includes both nicotine and flavoring agents.

[0074] In some embodiments, the aerosol generating matrix includes a solid matrix that is solid at room temperature, including but not limited to tobacco, tobacco shreds, or solid particles.

[0075] Furthermore, the atomizer 2 includes a heating element for heating the solid matrix. The heating element releases heat to cause the solid matrix to produce volatile substances, thereby generating an aerosol. This heating element for heating the solid matrix may include at least one of an external heating element, an internal heating element, and an air heating element. As used herein, an "external heating element" refers to a heating element that provides heat or radiates infrared radiation from the outside of the solid matrix to heat it. An "internal heating element" refers to a heating element that provides heat or radiates infrared radiation from the inside of the solid matrix to heat it. An "air heating element" refers to a heating element positioned upstream of the solid matrix along the airflow direction to heat air, which then flows into the solid matrix to heat it.

[0076] In some embodiments, the aerosol generating matrix includes a paste-like matrix that is in the form of a paste at room temperature.

[0077] In some embodiments, the aerosol generating matrix includes a liquid matrix that is liquid at room temperature. Further, the atomizer 2 includes an atomizing core 21 for atomizing the liquid matrix, thereby generating an aerosol.

[0078] As an example, the atomizing core 21 includes a liquid-absorbing element and a heating element, with the heating element disposed on the liquid-absorbing element. The liquid-absorbing element can be a porous body used to guide the aerosol-generating matrix into the atomization range of the heating element. The heating element is used to heat the atomized aerosol-generating matrix, thereby generating an aerosol. The porous body can be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber, or nylon fiber. The porous body can be porous ceramic or porous metal; this application does not limit the structure and composition of the porous body.

[0079] Of course, the atomizing core 21 may also include an ultrasonic element capable of generating ultrasonic waves, which enables the atomizing core to atomize the liquid matrix into an aerosol using ultrasonic waves. The atomizing core may also include other elements capable of atomizing the aerosol-generating matrix into an aerosol.

[0080] In some embodiments, reference may be made to Figure 2 The atomizer 2 includes a cup body 22, which has a storage cavity inside for storing the aerosol generation matrix. When the liquid matrix is ​​stored in the storage cavity, the atomizing core 21 is in fluid communication with the storage cavity, so that the atomizing core 21 can atomize at least a portion of the liquid matrix stored in the storage cavity.

[0081] In some embodiments, the atomizer 2 further includes a tube 23, which guides the aerosol generated by the atomizing core 21 from the aerosol generating matrix to the outlet 41 of the aerosol generating device 100, so that the aerosol flows out of the aerosol generating device 100 through the outlet 41. Further, see... Figure 2At least a portion of the tube 23 is located in the storage cavity, the tube 23 is configured to extend longitudinally in the storage cavity, and the tube 23 is connected to the nozzle 4 of the aerosol generating device.

[0082] The mouthpiece 4 is provided with an air outlet 41. At least a portion of the mouthpiece 4 can be held in the mouth by a user, and when the user holds the mouthpiece 4, the air outlet 41 is oriented towards the user's oral cavity. The user inhales the aerosol generated by the atomizer 2 by sucking on the mouthpiece 4.

[0083] In some embodiments, at least a portion of the atomizing core 21 is held in the tube 23. Further, the sidewall of the tube 23 has a liquid guiding hole for guiding the aerosol generating matrix in the storage cavity into the atomizing core 21. Preferably, at least a portion of the liquid guiding hole is located in the first storage cavity.

[0084] In other embodiments, reference may be made to Figure 2 The atomizer 2 also includes a compartment located upstream of the tube 23 along the airflow direction. The atomizing core 21 is disposed in the compartment. The compartment is connected to the storage chamber through a liquid channel, so that the aerosol generation matrix in the storage chamber can be transferred to the atomizing core 21. The compartment is fluidly connected to the tube 23, so that the aerosol formed in the compartment can be discharged by the tube 23.

[0085] In some embodiments, the atomizer 2 further includes a liquid reservoir element 24 having a large number of pores 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 within the liquid reservoir element 24, thereby preventing leakage of the aerosol-generating matrix from the storage cavity. The liquid reservoir element 24 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.

[0086] For ease of description, two of the multiple atomizers 2 included in the aerosol generating device 100 are defined as a first atomizer 25 and a second atomizer 26. The first atomizer 25 and the second atomizer 26 may have the same structural features. Alternatively, the first atomizer 25 and the second atomizer 26 may have different structural features.

[0087] In some embodiments, both the first atomizer 25 and the second atomizer 26 have a storage cavity for storing the aerosol generating matrix. Based on this, as an example, the composition or ratio of the aerosol generating matrix stored in the first atomizer 25 and the second atomizer 26 can be different, thereby enabling the first atomizer 25 and the second atomizer 26 to produce aerosols with different flavors or textures. Of course, the first atomizer 25 and the second atomizer 26 can also store the exact same aerosol generating matrix, thereby enabling them to produce aerosols with the same flavor and texture.

[0088] The power source 1 can be any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery. In some embodiments, the control component 3 includes a circuit board 31 electrically connected to the power source 1. The circuit board 31 has at least one controller, which controls the electrical power output of the power source 1, for example, controlling the power supply power of the power source 1 to the atomizer 2. Of course, the controller can also control other operations of the aerosol generating device 100, such as controlling the charging of the power source 1, thereby performing charging management and charging protection for the power source 1.

[0089] In some embodiments, the first atomizer 25 and the second atomizer 26 are configured to be selectable as at least one of the working atomizers. The working atomizer receives electrical power from the power source 1 when the aerosol generating device 100 is drawn in, thereby atomizing the aerosol generating matrix to produce aerosol. The non-working atomizer is configured to be unable to be drawn in or to not receive electrical power from the power source 1 when the aerosol generating device is drawn in, thus preventing it from atomizing the aerosol generating matrix and producing aerosol.

[0090] In some embodiments, the first atomizer 25 and the second atomizer 26 are configured to be working atomizers simultaneously.

[0091] In some embodiments, the first atomizer 25 and the second atomizer 26 are configured not to be working atomizers at the same time, and at most one of them can be a working atomizer at any given time.

[0092] In some embodiments, reference may be made to Figure 2 and Figure 3 The control component 3 includes a switch 34, a first sensor 32, and a second sensor 33. The switch 34 is configured to selectively enable at least one of the first sensor 32 and the second sensor 33 to receive electrical power supplied by the power source 1, thereby entering a sensing state. The first sensor 32 is configured, in the sensing state, to respond to changes in airflow in the first atomizer 25 and control the power source 1 to provide electrical power to the first atomizer 25, causing the first atomizer 25 to generate aerosol. The second sensor 33 is configured, in the sensing state, to respond to changes in airflow in the second atomizer 26 and control the power source 1 to provide electrical power to the second atomizer 26, causing the second atomizer 26 to generate aerosol.

[0093] Therefore, the sensor corresponding to the working atomizer can be controlled to enter the sensing state by the switching device, and the sensor corresponding to the non-working atomizer can be controlled to enter the non-sensing state. When the sensor is in the non-sensing state, the circuit between it and the power supply 1 can be disconnected, or the power supply 1 can provide it with 0W, or the sensor in the non-sensing state can be prevented from entering the sensing state due to lack of energy or insufficient energy by other means, thereby helping to reduce the power consumption of the power supply 1 and extend the battery life of the aerosol generating device 100.

[0094] In some embodiments, reference may be made to Figure 3 and Figure 4 The switching element 34 includes an operating element 341 that can be driven to move or be driven to deform. The operating element 341 is operable, and the control component 3 is configured to select at least one of the first sensor 32 and the second sensor 33 to enter a sensing state based on the position, shape, direction of movement, and / or number of times the operating element 341 is operated. It should be noted that a change in the position of the operating element 341 includes spatial displacement of the operating element 341 or rotation of the operating element 341.

[0095] In some embodiments, when the actuating member 341 is configured to be driven to move along a first direction, it controls the first sensor 32 to enter a sensing state. The control component 3 may also include a reset member (not shown) that acts on the actuating member 341 to automatically reset the actuating member to its initial position after the driving force applied to the actuating member is removed, and the first sensor may continue to maintain the sensing state when the actuating member is reset to its initial position.

[0096] Furthermore, the operating element 341 is configured to control the second sensor 33 to enter a sensing state when it is driven again to move along the first direction again. The reset element can automatically reset the operating element 341 to its initial position after the driving force applied to the operating element 341 is removed, and the second sensor 33 can continue to maintain the sensing state when the operating element is reset to its initial position.

[0097] Furthermore, the operating element 341 is configured to, when driven for the third time to move along the first direction again, control the first sensor 32 and the second sensor 33 to simultaneously enter the sensing state, or select the first sensor 32 to enter the sensing state again, or select the first sensor 32 and the second sensor 33 to simultaneously enter the non-sensing state.

[0098] In some embodiments, when the operating member 341 is configured to be driven to move in a second direction different from the first direction, the second sensor 33 is controlled to enter a sensing state. A reset member can automatically reset the operating member 341 to its initial position after the driving force applied to it is removed, and the second sensor 33 can continue to maintain the sensing state when the operating member 341 is reset to its initial position. The first direction and the second direction can be opposite in direction, but are not limited thereto.

[0099] In some embodiments, the actuator 341 is configured to move between a first position and a second position, and to control the first sensor 32 to enter a sensing state when in the first position, and to control the second sensor 33 to enter a sensing state when in the second position. As an example, the actuator 341 is configured to move along a straight or curved trajectory between the first and second positions. Alternatively, the actuator 341 is configured to be rotatable, and may have the same spatial coordinates when in the first and second positions.

[0100] In some embodiments, the operating member 341 is configured to also move to a third position, and the first sensor 32 and the second sensor 33 are configured to be in a non-sensing state when the operating member 341 is in the third position; or the aerosol generating device 100 is configured to shut down when the operating member 341 is in the third position, thereby causing the first sensor 32 and the second sensor 33 to be in a non-sensing state. The third position is a position different from the first position and the second position. Preferably, the third position is between the first position and the second position.

[0101] In some embodiments, the actuating member 341 is configured to also move to a fourth position, and the first sensor 32 and the second sensor 33 are configured to both be in a sensing state when the actuating member 341 is in the fourth position. The fourth position is a position different from the first position and the second position.

[0102] In some embodiments, the switching element 34 includes a first switching element 342 and a second switching element 343. The first sensor 32 is configured to enter a sensing state when the first switching element 342 is triggered, and the second sensor 33 is configured to enter a sensing state when the second switching element 343 is triggered. Therefore, by triggering the first switching element 342 alone, only the first sensor 32 and the second sensor 33 can enter the sensing state. Similarly, by triggering the second switching element 343 alone, only the second sensor 33 can enter the sensing state.

[0103] In some embodiments, at least a portion of both the first switch 342 and the second switch 343 is exposed, allowing them to be operated and triggered independently. For example, the aerosol generating device 100 further includes a housing 5. The first switch 342 includes a first button (not shown) exposed outside the housing 5, which can be triggered by pressing, sliding, or rotating the first button. The second switch 343 includes a second button (not shown) exposed outside the housing 5, which can be triggered by pressing, sliding, or rotating the second button. The first and second buttons are independently configured and can be operated separately.

[0104] In some embodiments, reference may be made to Figure 3 and Figure 4 The switching element 34 also includes an operating element 341, which is configured to move between a first position and a second position, triggering a first switching element 342 when in the first position and triggering a second switching element 343 when in the second position. Thus, the first switching element 341 and / or the second switching element 342 can be selectively triggered by changing the position of the operating element 341. In this embodiment, the first switching element 342 and the second switching element 343 can be concealed inside the aerosol generating device 100.

[0105] Furthermore, the switching element 34 also includes a trigger element 344 that is linked to the operating element 341. For example, the trigger element 344 is held on the operating element 341, so that the trigger element 344 can move or deform with the operating element 341. Or, for example, the trigger element 344 is held on the circuit board 31, and the operating element 341 can drive at least a partial movement or deformation of the trigger element 344.

[0106] The operating element 341 is configured to trigger the first switch element 342 via the trigger element 344 when it is in the first position, and to trigger the second switch element 343 via the trigger element 344 when it is in the second position.

[0107] In some embodiments, the first switching element 342 includes an inductive switch, and the trigger element 344 is provided with a sensing element (not shown) that can be sensed by the inductive switch. For example, when the inductive switch includes a magnetic inductive switch, the sensing element includes a magnetic element capable of generating a magnetic field, and the magnetic element may include a magnet. The first switching element 342 can be triggered by moving or deforming the trigger element 344, thereby causing the sensing element to move closer to or away from the inductive switch included in the first switching element 342. Further, the second switching element 343 also includes an inductive switch, thereby triggering the second switching element 343 when the sensing element 541 moves closer to or away from the inductive switch included in the second switching element 343. The inductive switch includes, but is not limited to: infrared inductive switches, microwave inductive switches, ultrasonic inductive switches, piezoelectric inductive switches, electromagnetic inductive switches, capacitive inductive switches, etc. The first switching element 342 and the second switching element 343 may include the same inductive switch or may include different inductive switches.

[0108] It should be noted that the trigger 344 may be provided with only one sensing element, and the first switch 342 and the second switch 343 may be triggered by the same sensing element; or the trigger 344 may be provided with two sensing elements, and the first switch 342 and the second switch 343 may be triggered by different sensing elements.

[0109] In some embodiments, the first switching element 342 includes a contact switch, which is triggered by physical contact. A trigger element 344 is provided with a trigger portion (not shown). By moving or deforming the trigger element 344, the trigger portion can be moved closer to or away from the contact switch included in the first switching element 342, thereby triggering the first switching element 342. Furthermore, the second switching element 343 also includes a contact switch, so by moving the trigger element 344, the trigger portion can be moved closer to or away from the contact switch included in the second switching element 343, thereby triggering the second switching element 343. The contact switch includes, but is not limited to, microswitches, tactile switches, toggle switches, push-button switches, and key switches.

[0110] It should be noted that the trigger 344 may be provided with only one trigger part, and the first switch 342 and the second switch 343 may be triggered by the same trigger part; or the trigger 344 may be provided with two trigger parts, and the first switch 342 and the second switch 343 may be triggered by different trigger parts.

[0111] In some embodiments, reference may be made to Figure 5The first switching element 342 includes a first pin 3421 and a second pin 3422. A trigger element 344 is configured to connect the first pin 3421 and the second pin 3422 when the operating element 341 is in a first position, such that the first pin 3421 and the second pin 3422 are electrically connected, or that the impedance between the first pin 3421 and the second pin 3422 is changed, thereby triggering the first switching element 342. Furthermore, the first pin 3421 and the second pin 3422 are spaced apart, and when the operating element 341 is in a second position, the circuit between the first pin 3421 and the second pin 3422 is disconnected.

[0112] In some embodiments, reference may be made to Figure 5 The second switching element 343 includes a third pin 3431 and a fourth pin 3432. The trigger element 344 is configured to connect the third pin 3431 and the fourth pin 3432 when the operating element 341 is in the second position, such that the third pin 3431 and the fourth pin 3432 are electrically connected, or that the impedance between the third pin 3431 and the fourth pin 3432 changes, thereby triggering the second switching element 343. Furthermore, the third pin 3431 and the fourth pin 3432 are spaced apart, and when the operating element 341 is in the first position, the circuit between the third pin 3431 and the fourth pin 3432 is disconnected.

[0113] In some embodiments, reference may be made to Figure 5 The trigger 344 includes a damping portion 3442, a base 3441, and a moving portion 3443 movably disposed on the base 3441 and driven to move by the operating member 341. The moving portion 3443 is configured to approach or contact the first switch 342 when the operating member 341 is in a first position, thereby triggering the first switch 342; and to approach or contact the second switch 343 when the operating member 341 is in a second position, thereby triggering the second switch 343.

[0114] The first switch element 342 and the second switch element 343 are held at a distance from each other on the base 3441. At least a portion of the damping element 3442 is located between the first switch element 342 and the second switch element 343 to provide damping when the operating element 341 drives the moving part 3443 to move. On the one hand, this helps prevent the moving part 3443 from moving from being close to or in contact with the first switch element 342 to being close to or in contact with the second switch element 343, or from being close to or in contact with the second switch element 343 to being close to or in contact with the first switch element 342, without the driving of the operating element or without expectation. It also helps to keep the operating element 341 more stably in the first or second position. On the other hand, it also provides a tactile feedback for the user when selecting the sensor to enter the sensing state through the operating element 341, and also indicates that the first switch element 342 or the second switch element 343 has been triggered.

[0115] In such Figure 5 In the illustrated embodiment, the trigger 344 further includes an elastically deformable spring arm 3444, which can be connected to the base 3441. A damping portion 3442 is disposed on the spring arm 3444, so that during the movement of the operating member 341 between the first and second positions, the damping portion 3442 can yield under the compression or interference of the moving portion 3443, thereby reducing wear on the damping portion 3442 and the moving portion 3443. The base 3441, the spring arm 3444, and the damping portion 3442 can be integrally injection molded. In other embodiments, the damping portion 3442 itself is configured to be elastically deformable to yield appropriately under the compression or interference of the moving portion 3443.

[0116] It should be noted that the moving part 3443 may include the triggering part or the sensing component described above, or the triggering part / sensing component described above may be disposed on the moving part 3443.

[0117] In some embodiments, the aerosol generating device 100 further includes an air inlet (not shown) for guiding air into the aerosol generating device. When the aerosol generating device 100 is drawn in, outside air can enter the working atomizer through the air inlet, thereby causing changes in the airflow in the working atomizer, including changes in at least one of the direction, velocity, and pressure of the airflow in the working atomizer.

[0118] The air inlet may be one or more. The first atomizer 25 and the second atomizer 26 may be in fluid communication with the same air inlet. Alternatively, the air inlet may include a first air inlet for fluid communication only with the first atomizer 25 and a second air inlet for fluid communication only with the second atomizer 26.

[0119] In some embodiments, the switch 34 is further configured to open the air passage between the first atomizer 25 and the air inlet when the first sensor 32 is in a sensing state, and to close the air passage between the second atomizer 33 and the air inlet.

[0120] For example, when the first atomizer 25 is the working atomizer and the second atomizer 26 is the non-working atomizer, the first sensor 32 can be selected to enter the sensing state by the switch 34, and the switch 34 opens the air passage between the first atomizer 25 and the air inlet, so that during inhalation, outside air can enter the first atomizer 25 and cause a change in the airflow of the first atomizer 25. The first sensor 32 responds to the change in airflow of the first atomizer 25 to control the power supply 1 to provide electrical power to the first atomizer 25, so that the first atomizer 25 atomizes the aerosol generation matrix to produce aerosol. Figure 2 In the illustrated embodiment, the first atomizer 25 and the second atomizer 26 share the same mouthpiece 4, so that the airflow flowing through the first atomizer (working atomizer) 25 and the airflow flowing through the second atomizer (non-working atomizer) 26 can be discharged from the aerosol generating device 100 through the same air outlet 41. The switching element 34 opens the air passage between the first atomizer 25 and the air inlet while closing the air passage between the second atomizer 26 and the air inlet. This helps to prevent the airflow containing aerosol output from the first atomizer 25 from mixing with the airflow mainly composed of air flowing into the air outlet 41 through the second atomizer 26 during inhalation, thereby reducing the concentration of aerosol at the air outlet 41 and causing a decrease in taste.

[0121] In some embodiments, the switch 34 is further configured to open the air passage between the second atomizer 26 and the air inlet when the second sensor 33 is in a sensing state, and to close the air passage between the first atomizer 25 and the air inlet.

[0122] In some embodiments, when the air passage between the first atomizer 25 and the corresponding air inlet is open, the air passage between the first sensor 32 and the air inlet is also open, so that when the inhalation stops, the air pressure at the sensing surface of the first sensor 32 is balanced with the air pressure at its reference surface.

[0123] In some embodiments, when the air passage between the second atomizer 26 and the corresponding air inlet is open, the air passage between the second sensor 33 and the air inlet is also open, so that when the inhalation stops, the air pressure at the sensing surface of the second sensor 33 is balanced with the air pressure at its reference surface.

[0124] In some embodiments, the switch 34 includes an operating member 341 movable between a first position and a second position. The operating member 341 is configured to control the first sensor 32 to enter a sensing state when in the first position, and to open the air passage between the first atomizer 25 and the air inlet. This enables the first sensor 32 to sense changes in airflow in the first atomizer 25 and to control the power supply 1 to provide electrical power to the first atomizer 25, while allowing a large amount of outside air to enter the first atomizer 25 during inhalation.

[0125] As an example, you can refer to Figure 4 and Figure 6 The control component 3 also includes a base 35, on which a first air inlet 3511 is provided. The first air inlet 3511 is located between the air inlet and the first atomizer 25 along the airflow direction. Further, the operating member 241 is configured to open the first air inlet 3511 when in the first position, thereby allowing air entering from the air inlet to flow into the first atomizer 25, thus opening the air passage between the first atomizer 25 and the air inlet. And / or, when the operating member 314 is in the second position, the air passage between the first atomizer 25 and the air inlet can be disconnected by sealing the first air inlet 3511 with the operating member 341, thereby disconnecting the air passage between the first atomizer 25 and the air inlet when the operating member 241 is in the second position.

[0126] In some embodiments, the operating member 341 is configured to control the second sensor 33 to enter a sensing state when in the second position, and to open the air passage between the second atomizer 26 and the air inlet. This enables the second sensor 33 to sense changes in airflow in the second atomizer 26 and to control the power supply 1 to provide electrical power to the second atomizer 26, while allowing a large amount of outside air to enter the second atomizer 26 during inhalation.

[0127] As an example, you can refer to Figure 4 and Figure 6 A second air inlet 3512 is provided on the base 35, located between the air inlet and the second atomizer 26 along the airflow direction. Further, the operating member 341 is configured to open the second air inlet 3512 when in the second position, thereby allowing air entering from the air inlet to flow into the second atomizer 26, thus opening the air passage between the second atomizer 26 and the air inlet. And / or, when the operating member 341 is in the first position, the air passage between the second atomizer 26 and the air inlet can be disconnected by sealing the second air inlet 3512, thereby disconnecting the air passage between the second atomizer 26 and the air inlet when the operating member 341 is in the first position.

[0128] In some embodiments, reference may be made to Figure 8 The operating member 341 includes an operating part 3411 and a first sealing part 3412. The operating part 3411 can be operated to drive the moving part 3443 to move and drive the first sealing part 3412 to move. When the operating member 341 is in the first position, the first switch 342 is triggered, causing the first sensor 32 to enter the sensing state. At the same time, the first air inlet 3511 is sealed by the first sealing part 3412 to prevent air from entering the first atomizer 25 through the air inlet.

[0129] As an example, along the direction of airflow, when the operating member 341 is in the first position, the first sealing part 3412 blocks air from entering the first air inlet 3511 upstream of the first air inlet 3511, thereby disconnecting the air passage between the air inlet and the first air inlet 3511.

[0130] As an example, at least one of the base 35 and the first sealing portion 3412 includes a sealing ring made of a flexible material, including but not limited to silicone. When the operating member 341 is in the first position, the sealing ring elastically deforms to provide a seal between the base 35 and the operating member 341. Further, see... Figure 7 and Figure 8 The base 35 is provided with a first sealing ring 3513, and the first sealing part 3412 includes a second sealing ring. When the operating member 341 is in the first position, the first sealing ring 3513 and the second sealing ring are arranged end-to-end facing each other, so that they are in direct contact; or, when the operating member 341 is in the first position, one of the first sealing ring 3513 and the second sealing ring is arranged around the periphery of the other, so that they are arranged side-to-side facing each other. Furthermore, the base 35 includes a rubber article 351, at least a portion of the first air inlet 3511 is defined by the rubber article 351, and the rubber article 351 has an annular protrusion arranged around the first air inlet 3511, which forms the first sealing ring 3513.

[0131] As an example, the operating element 341 further includes a connecting portion 3413, on which the operating portion 3411 and the first sealing portion 312 are connected, and the operating portion 3411 and the first sealing portion 3412 are disposed on opposite sides of the connecting portion 3413. The operating portion 3411 can drive the connecting portion 3413 to move, thereby driving the moving part 3443 to move through the connecting portion 3413, thereby triggering the first switching element 342 and / or the second switching element 343. Furthermore, the first switch 342 and the second switch 343 are disposed inside the housing 5. A through hole 51 is provided on the housing 5. At least a portion of the operating part 3411 is located in the through hole 51, and the operating part 3411 is configured to occupy only a portion of the space in the through hole 51, so that the operating part 3411 can be displaced in the through hole 51 along the extension direction of the through hole 51 on the housing 5. The connecting part 3413 is disposed corresponding to the through hole 51 and is located inside the through hole 51. At least a portion of the connecting part 3413 is exposed through the through hole 51 and partially hidden in the housing 5, so that the connecting part 3413 cannot be detached from the housing 5 by passing through the through hole 51. The operating part 3411 is connected to the front of the connecting part 3413 and is thus exposed, while the first sealing part 3412 is connected to the back of the connecting part 3413 and is thus covered and hidden.

[0132] In some embodiments, reference may be made to Figure 7 The base 35 also includes a first retaining cavity 3515, in which the first sensor 32 is at least partially and hermetically held. For example, when the first sensor 32 is at least partially disposed in the first retaining cavity 3515, a hermetically sealed connection is formed between the sidewall of the first sensor 32 and the base 35 to prevent airflow outside the sensing surface and outside the reference surface of the first sensor 32 from flowing through the gap between the sidewall of the first sensor 32 and the base 25. The sidewall of the first sensor 32 is located between the sensing surface and the reference surface of the first sensor 32.

[0133] Furthermore, a first flow guide hole 3516 is provided on the base 35, which connects the first atomizer 25 and the first holding cavity 3515, allowing the first sensor 32 to be in fluid communication with the first atomizer 25 through the first flow guide hole 3516. The sensing surface of the first sensor 32 can be positioned facing the opening of the first flow guide hole 3516 towards the interior of the first holding cavity 3515, or the sensing surface of the first sensor 32 can be offset from the opening of the first flow guide hole 3516 towards the interior of the first holding cavity 3515. The first sensor 32 can sense changes in the airflow in the first atomizer 26 by sensing changes in the airflow in the first flow guide hole 3516.

[0134] Furthermore, one can refer to Figure 6The base 35 also includes a first chamber 3517 that fluidly communicates with the first atomizer 25 and the first air inlet 3511. One end of the first guide hole 3516 is located in or facing the first chamber 3517. Thus, the first air inlet 3511 and the first guide hole 3516 are fluidly communicated through the first chamber 3517.

[0135] Preferably, the first guide hole 3516 is opposite to the opening of the first holding cavity 3515 and is higher than the bottom of the first chamber 3517 to prevent liquid from flowing from the first chamber 3517 into the first holding cavity 3515.

[0136] In some embodiments, reference may be made to Figure 7 and Figure 8 The operating member 341 includes an operating part 3411 and a second sealing part 3414. The operating part 3411 can be operated to drive the moving part 3443 and the second sealing part 3414 to move. When the operating member 341 is in the second position, the second switch 343 is triggered, causing the second sensor 33 to enter the sensing state. At the same time, the second air inlet 3512 is sealed by the second sealing part 3414 to prevent air from entering the second atomizer 26 through the air inlet.

[0137] As an example, along the direction of airflow, when the operating member 341 is in the second position, the second sealing part 3414 blocks air from entering the second air inlet 3512 upstream of the second air inlet 3512, thereby disconnecting the air passage between the air inlet and the second air inlet 3512.

[0138] As an example, at least one of the base 35 and the second sealing part 3414 includes a sealing ring made of a flexible material. When the operating member 341 is in the second position, the sealing ring elastically deforms to provide a seal between the base 35 and the operating member 341. Further, see... Figure 7 The base 35 is provided with a third sealing ring 3514, and the second sealing part 3141 includes a fourth sealing ring. When the operating member 341 is in the second position, the third sealing ring 3514 and the fourth sealing ring are arranged end-to-end facing each other, so that they are in direct contact; or, when the operating member 341 is in the second position, one of the third sealing ring 3514 and the fourth sealing ring is arranged around the periphery of the other, so that they are arranged side-to-side facing each other. Furthermore, the base 35 includes a rubber article 351, at least a portion of the second air inlet 3512 is defined by the rubber article 35, and the rubber article 351 has an annular protrusion arranged around the second air inlet 3512, which forms the second sealing ring 3514.

[0139] As an example, the operating component 341 also includes a connecting portion 3413, on which the operating portion 3411 and the second sealing portion 3414 are connected, and the operating portion 3411 and the second sealing portion 3414 are disposed on opposite sides of the connecting portion 3413. Furthermore, the second sealing portion 3414 is connected to the back side of the connecting portion 3413 and is thus covered and hidden.

[0140] Preferably, the first sealing part 3412 and the second sealing part 3414 are integrally formed.

[0141] In some embodiments, reference may be made to Figure 6 and Figure 7 The base 35 also includes a second retaining cavity 3518, in which the second sensor 33 is at least partially and hermetically held. For example, when the second sensor 33 is at least partially disposed in the second retaining cavity 3518, a hermetically sealed connection is formed between the sidewall of the second sensor 33 and the base 35 to prevent airflow outside the sensing surface and outside the reference surface of the second sensor 33 from flowing through the gap between the sidewall of the second sensor 33 and the base 35. The sidewall of the second sensor 33 is located between the sensing surface and the reference surface of the second sensor 33.

[0142] Furthermore, a second flow guide hole 3519 is provided on the base 35, which connects the second atomizer 26 and the second holding cavity 3518, allowing the second sensor 26 to be in fluid communication with the second atomizer 26 through the second flow guide hole 3519. The sensing surface of the second sensor 33 can be positioned facing the opening of the second flow guide hole 3519 towards the interior of the second holding cavity 3518, or the sensing surface of the second sensor 33 can be offset from the opening of the second flow guide hole 3519 towards the interior of the second holding cavity 3518. The second sensor 33 can sense changes in airflow in the second atomizer 26 by sensing changes in airflow in the second flow guide hole 3519.

[0143] Furthermore, one can refer to Figure 6 The base 35 also includes a second chamber 3520 that is fluidly connected to the second atomizer 26 and the second air inlet 3512. One end of the second guide hole 3519 is located in or facing the second chamber 3520. Thus, the second air inlet 3512 and the second guide hole 3519 are fluidly connected through the second chamber 3520.

[0144] Preferably, the second guide hole 3519 is opposite to the opening of the second retaining cavity 3518 and is higher than the bottom of the second chamber 3520 to prevent liquid from flowing from the second chamber 3520 into the second retaining cavity 3518.

[0145] In some embodiments, the base 35 includes a support 352 and a rubber article 351 held by the support 352. At least one of a first holding cavity 3515, a first air inlet 3511, a first chamber 3517, and a first guide hole 3516 is provided on the rubber article 351. And / or, at least one of a second holding cavity 3518, a second air inlet 3512, a second chamber 3520, and a second guide hole 3519 is provided on the rubber article 351.

[0146] In some embodiments, one of the operating member 341 and the bracket 352 is provided with a slide rail 3521, and the other is provided with a sliding part 3415 that can slide along the slide rail 3521.

[0147] For example, you can refer to Figure 8 and Figure 9 The connecting part 3413 is provided with a sliding part 3415, and the bracket 352 is provided with a grooved slide rail 3521. At least a portion of the sliding part 3415 is slidably disposed in the slide rail 3415, so that when the operating part 3411 drives the connecting part 3413 to move along the slide rail 3415, the connecting part 3413 can be prevented from separating from the bracket 352 in a direction perpendicular to the sliding direction.

[0148] In some embodiments, at least a portion of the operating element 341 is exposed through a through-hole 51 on the housing 5 to be operable, wherein the air inlet may include a hole penetrating the operating element 341, and / or the air inlet includes a gap between the operating element 341 and the housing 5. Thus, outside air can enter the corresponding atomizer 2 through the operating element 341 and / or from the gap between the operating element 341 and the housing 5, and then through the open air inlet.

[0149] In some embodiments, reference may be made to Figure 2 and Figure 10 The first sensor 32 and the second sensor 33 are electrically connected to the circuit board 31, thereby connecting the circuit board 31 to the first switch 342 and the second switch 343. The first switch 342 or / or the second switch 343 can be triggered by the trigger 344, causing either the first sensor 32 or the second sensor 33 to enter a sensing state.
