[0069] Please refer to Figure 1 and Figure 2 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.

[0070] In some embodiments, the atomizer 2 includes an atomizing core 26, which, when powered, atomizes an aerosol generation matrix to generate an aerosol.

[0071] 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.

[0072] 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.

[0073] Of course, the atomizing core 26 may also include other elements that enable the liquid matrix to be atomized into an aerosol.

[0074] In some embodiments, the atomizer 2 includes a storage chamber 23 for storing an aerosol generation matrix. When the storage chamber 23 is used to store a liquid matrix, the storage chamber 23 is in fluid communication with the atomizing core 26, so that the liquid matrix stored in the storage chamber 23 can flow to the atomizing core 26 and be atomized by the atomizing core 26.

[0075] The aerosol generating matrix stored in the storage chamber 23 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 23 of different atomizers 2 can be different, so that different atomizers 2 can produce aerosols with different flavors or aromas.

[0076] 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 areca nut extract, 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.

[0077] In some embodiments, the atomizer 2 further includes an air guide tube 24, which is in fluid communication with the atomizing core 26 and can guide the aerosol generated by the atomizing aerosol matrix generated by the atomizing core 26 to the corresponding atomizer 2.

[0078] At least a portion of the atomizing core 26 may be disposed within the air delivery tube 24. Alternatively, the atomizer 2 may further include a compartment in which the atomizing core 26 is disposed. The compartment is connected to the storage chamber 23 via a liquid channel, allowing the liquid matrix in the storage chamber 23 to be transferred to the atomizing core 26. The compartment is in fluid communication with the air delivery tube 24, allowing the aerosol formed in the compartment to be discharged through the air delivery tube 24.

[0079] 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.

[0080] The atomizer 2 also includes a mouthpiece 25 with an air inlet 251. The air inlet 251 is used to discharge the aerosol generated by the atomizer 2. When the mouthpiece 25 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 251 is positioned towards the user's mouth, so that the user can inhale the aerosol generated by the atomizer 2 by inhaling through the mouthpiece 25.

[0081] In some embodiments, if the aerosol generating matrix comprises a solid matrix, the atomizer 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. The heating element for heating the stationary 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 the stationary matrix. 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 the stationary matrix. An "air heating element" refers to a heating element disposed upstream of the stationary matrix along the airflow direction for heating air, which then flows into the stationary matrix to heat the solid matrix.

[0082] The fixing matrix includes, but is not limited to: tobacco, shredded tobacco, granules, flakes or strips.

[0083] For ease of description, two of the multiple atomizers 2 are defined as the first atomizer 21 and the second atomizer 22. The first atomizer 21 is configured to move relative to the housing 1, and the second atomizer 22 is also configured to move relative to the housing 1. Furthermore, the first atomizer 21 and the second atomizer 22 are linked, so that when the position of the first atomizer 21 changes or moves, the position of the second atomizer 22 changes or moves accordingly.

[0084] In some embodiments, the aerosol generating device 100 further includes a support 3, and the first atomizer 21 and the second atomizer 22 can be connected to the support 3 at the same time, so that the first atomizer 21 and the second atomizer 22 can be linked together through the support 3.

[0085] Furthermore, the support 3 is disposed inside the housing 1, and the support 3 is configured to move relative to the housing 1 between a first position and a second position. When the support 3 is in the first position, the mouthpiece 25 of the first atomizer 21 extends from the housing 1, allowing the user to hold the mouthpiece 25 of the first atomizer 21 in their mouth, thus enabling the first atomizer 21 to be used and generate aerosol. When the support 3 is in the second position, the mouthpiece 25 of the second atomizer 22 extends from the housing 1, allowing the user to hold the mouthpiece 25 of the second atomizer 22 in their mouth, thus enabling the second atomizer 22 to be used and generate aerosol.

[0086] Furthermore, when the support 3 is in the first position, the mouthpiece of the second atomizer 22 is located within the housing 1, thus the circumference of the mouthpiece 25 of the second atomizer 22 is blocked by the housing 1, preventing the user from holding the mouthpiece 25 of the second atomizer 22 in their mouth and keeping it clean and hygienic. When the support 3 is in the second position, the mouthpiece 25 of the first atomizer 21 is located within the housing 1, thus the circumference of the mouthpiece 25 of the first atomizer 21 is blocked by the housing 1, preventing the user from holding the mouthpiece 25 of the first atomizer 21 in their mouth and keeping it clean and hygienic.

[0087] In some embodiments, the housing 1 has a proximal end and a distal end disposed opposite to each other. When the support 3 is in a first position, the mouthpiece 25 of the first atomizer 21 extends from the proximal end of the housing 1, and when the support 3 is in a second position, the mouthpiece 25 of the second atomizer 22 extends from the distal end of the housing 1.

[0088] In some embodiments, reference may be made to Figure 2The aerosol generating device 100 also includes a power supply 4, which is configured to establish a power supply path between the support 3 and the first atomizer 21 when the support 3 is in a first position, thereby enabling the power supply 4 to provide electrical power for the first atomizer 21 to atomize the aerosol generating matrix and generate aerosols. When the support 3 is in a second position, the power supply 4 establishes a power supply path between the power supply 4 and the second atomizer 22, thereby enabling the power supply 4 to provide electrical power for the second atomizer 22 to atomize the aerosol generating matrix and generate aerosols.

[0089] The power source 4 may include any suitable battery, such as a lithium battery, a rechargeable battery, or a disposable battery. The power source 4 may include a sports charger, which is detachably connected to the housing 1 or the bracket 3.

[0090] In some embodiments, the aerosol generating device 100 further includes a controller for controlling the power supply 4 to provide electrical power to the first atomizer 21 or the second atomizer 22. Of course, the controller can also protect the power supply 4 or control other operations of the aerosol generating device 100. The controller may include 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 programs executable in the microprocessor. Furthermore, those skilled in the art will understand that the controller may include another type of hardware.

[0091] In some embodiments, reference may be made to Figure 2 The proximal and distal ends of the housing 1 are located at opposite ends of the housing 1 in the longitudinal direction. The bracket 3 is configured to move longitudinally between a first position and a second position. The power supply 4 is arranged laterally with the bracket 3 to prevent the power supply 4 from obstructing the longitudinal movement of the bracket 3.

[0092] Furthermore, the power supply 4 is disposed within the housing 1, and the aerosol generating device 100 also includes a partition plate 5 disposed within the housing 1, with the power supply 4 and the support 3 positioned on opposite sides of the partition plate 5. Even further, the support 3 is configured to move along the partition plate 5. Preferably, see [reference needed]. Figure 3 The surface of the partition plate 5 facing the bracket 3 includes a plane, and the bracket 3 is configured to move along the plane.

[0093] In some embodiments, reference may be made to Figure 3 and Figure 4 The aerosol generating device 100 also includes a power supply electrode 6 electrically connected to a power supply 4, the power supply 4 being configured to output electrical power through the power supply electrode 6. The power supply electrode 6 is configured to be electrically connected to a first atomizer 21 when the support 3 is in a first position, thereby establishing a power supply path between the power supply 4 and the first atomizer 21. When the support 3 is in a second position, the power supply electrode is electrically connected to a second atomizer 22, thereby establishing a power supply path between the power supply 4 and the second atomizer 22.

[0094] In some embodiments, reference may be made to Figure 3 The power supply electrode 6 includes a first power supply electrode 61 and a second power supply electrode 62, and the power supply 4 is configured to output electrical power independently through the first power supply electrode 61 and the second power supply electrode 62.

[0095] When the support 3 is in the first position, the first power supply electrode 61 is electrically connected to the first atomizer 21, so that the power supply 4 can output electrical power to the first atomizer 21 through the first power supply electrode 61. When the support is in the second position, the second power supply electrode 62 is electrically connected to the second atomizer 22, so that the power supply 4 can output electrical power to the second atomizer 22 through the second power supply electrode 62.

[0096] Furthermore, when the support 3 is in the first position, the electrical connection between the second power supply electrode 62 and the second atomizer 22 is disconnected, thus rendering the second atomizer 22 unusable. When the support 3 is in the second position, the electrical connection between the first power supply electrode 61 and the first atomizer 21 is disconnected, thus rendering the first atomizer 21 unusable.

[0097] There may be two first power supply electrodes 61, which are electrically connected to the positive and negative terminals of the power supply 4, respectively. When establishing a power supply path between the power supply 4 and the first atomizer 21, the two first power supply electrodes 61 are electrically connected to the two electrodes of the first atomizer 21, respectively.

[0098] There can be two second power supply electrodes 62, which are electrically connected to the positive and negative terminals of the power supply 4, respectively. When establishing a power supply path between the power supply 4 and the second atomizer 22, the two second power supply electrodes 62 are electrically connected to the two electrodes of the second atomizer 22, respectively.

[0099] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 includes a partition plate 5 disposed within a housing 1, and a support 3 configured to move along the partition plate 5 between a first position and a second position, wherein a power supply electrode 6 is held on the partition plate 5.

[0100] In such Figure 3 In the illustrated embodiment, the partition plate 5 extends longitudinally and has a transverse through hole, in which at least a portion of the power supply electrode 6 is held. Preferably, the end of the power supply electrode 6 facing the support 3 is substantially flush with the plane of the partition plate 5 facing the support 3.

[0101] Furthermore, at least four through holes are provided on the partition plate 5, and at least a portion of the first power supply electrode 61 and at least a portion of the second power supply electrode 62 are held in the corresponding through holes.

[0102] In some embodiments, reference may be made to Figure 4 , Figure 6 and Figure 7 The support 3 includes a retainer 33 facing the partition plate 5, and a first connecting electrode 71 is disposed on the retainer 33. The first connecting electrode 71 is configured to electrically connect the first atomizer 21 and the power supply electrode 6 when the support 3 is in the first position, thereby establishing a power supply path between the power source 4 and the first atomizer 21. Further, when the support 3 is in the first position, the first connecting electrode 71 electrically connects the first atomizer 21 and the first power supply electrode 61. The number of first connecting electrodes 71 can be equal to the number of first power supply electrodes 61, so that multiple first connecting electrodes 71 can be electrically connected to multiple first power supply electrodes 61 in a one-to-one correspondence.

[0103] Preferably, when the first connecting electrode 71 is electrically connected to the first power supply electrode 61, the first connecting electrode 61 and the first power supply electrode 71 are in elastic contact. For example, the first connecting electrode 61 includes a spring or a spring pin.

[0104] In some embodiments, reference may be made to Figure 4 , Figure 6 and Figure 7 The retainer 33 is also provided with a second connecting electrode 72. The second connecting electrode 72 is configured to electrically connect the second atomizer 22 and the power supply electrode 6 when the support 3 is in the second position, thereby establishing a power supply path between the power source 4 and the second atomizer 22. Furthermore, when the support 3 is in the second position, the second connecting electrode 72 is electrically connected to the second atomizer 22 and the second power supply electrode 62. The number of second connecting electrodes 72 can be equal to the number of second power supply electrodes 62, so that multiple second connecting electrodes 72 can be electrically connected to multiple second power supply electrodes 62 in a one-to-one correspondence.

[0105] Preferably, when the second connecting electrode 62 is electrically connected to the second power supply electrode 72, the second connecting electrode 62 and the second power supply electrode 72 are in elastic contact. For example, the second connecting electrode 62 includes a spring or a spring pin.

[0106] In some embodiments, reference may be made to Figure 6 The bracket 3 is provided with a first power-taking electrode 81, and the first connecting electrode 71 is electrically connected to the first atomizer 21 through the first power-taking electrode 81. The direction of the first power-taking electrode 81 connecting to the first atomizer 21 is basically perpendicular to the direction of the first connecting electrode 71 connecting to the power supply electrode 6.

[0107] Furthermore, the first power-taking electrode 81 is configured to be directly electrically connected to the first atomizer 21. When the first atomizer 21 is connected to the bracket 3, the first atomizer 21 can be electrically connected to the first power-taking electrode 81.

[0108] In such Figure 6 In the illustrated embodiment, the support 3 includes a first receiving cavity 311 for accommodating at least a portion of the first atomizer 21, and a portion of the first power-taking electrode 81 may be exposed in the first receiving cavity 311, so that when at least a portion of the first atomizer 21 is accommodated in the first receiving cavity 311, the first atomizer can establish an electrical connection with the first power-taking electrode.

[0109] The first power-taking electrode 82 can extend approximately longitudinally, and the first connecting electrode 72 can extend approximately laterally.

[0110] In some embodiments, the first atomizer 21 is configured to be removably housed in the first receiving cavity 311, thereby making the first atomizer 21 connected to the bracket 3 replaceable. Preferably, the opening of the first receiving cavity 311 is disposed toward the proximal end of the housing 1, and the first atomizer 21 is configured to be longitudinally fitted into the first receiving cavity 311 or longitudinally removed from the first receiving cavity 311.

[0111] In some embodiments, the direction of movement of the bracket 3 between the first position and the second position is perpendicular to the direction in which the first connecting electrode 71 is electrically connected to the power supply electrode 6. Further, the bracket 3 is configured to move longitudinally between the first position and the second position, thereby electrically connecting the first connecting electrode 71 and the power supply electrode 6 laterally.

[0112] Furthermore, the first connecting electrode 71 can move longitudinally relative to the power supply electrode 6 along with the bracket 3, and the first connecting electrode 71 can slide along the partition plate 5 while the bracket 3 moves longitudinally. When the bracket 3 is in the first position, the first connecting electrode 71 is aligned with and abuts against the power supply electrode 6 or the first power supply electrode 61, thereby establishing an electrical connection between the first connecting electrode 71 and the power supply electrode 6 or the first power supply electrode 61. When the bracket 3 is in the second position, the first connecting electrode 71 is offset from the power supply electrode 6 or the first power supply electrode 61, thereby disconnecting the electrical connection between the first connecting electrode 71 and the power supply electrode 6 or the first power supply electrode 61.

[0113] In some embodiments, reference may be made to Figure 6 The bracket 3 is provided with a second power-taking electrode 82, and the second connecting electrode 72 is electrically connected to the second atomizer 22 through the second power-taking electrode 82. The direction of the second power-taking electrode 82 connecting to the second atomizer 22 is basically perpendicular to the direction of the second connecting electrode 72 connecting to the power supply electrode 6.

[0114] Furthermore, the second power-taking electrode 82 is configured to be directly electrically connected to the second atomizer 22. When the second atomizer 22 is connected to the bracket 3, the second atomizer 22 can be electrically connected to the second power-taking electrode 82.

[0115] In such Figure 6In the illustrated embodiment, the support 3 includes a second receiving cavity 321 for accommodating at least a portion of the second atomizer 22, and a portion of the second power-taking electrode 82 may be exposed in the second receiving cavity 321, so that when at least a portion of the second atomizer 22 is accommodated in the second receiving cavity 321, the second atomizer 22 can establish an electrical connection with the second power-taking electrode 82.

[0116] The second power-taking electrode 82 can extend approximately longitudinally, and the second connecting electrode 72 can extend approximately laterally.

[0117] In some embodiments, the second atomizer 22 is configured to be removably housed in the second receiving cavity 321, thereby making the second atomizer 22 connected to the bracket 3 replaceable. Preferably, the opening of the second receiving cavity 321 is disposed toward the distal end of the housing 1, and the second atomizer 22 is configured to be longitudinally fitted into the second receiving cavity 321 or longitudinally removed from the second receiving cavity 321.

[0118] In some embodiments, the direction of movement of the bracket 3 between the first position and the second position is perpendicular to the direction in which the second connecting electrode 72 is electrically connected to the power supply electrode 6. Further, the bracket 3 is configured to move longitudinally between the first position and the second position, thereby electrically connecting the second connecting electrode 72 and the power supply electrode 6 laterally.

[0119] Furthermore, the second connecting electrode 72 can move longitudinally relative to the power supply electrode 6 along with the bracket 3, and the second connecting electrode 72 can slide along the partition plate 5 as the bracket 3 moves longitudinally. When the bracket 3 is in the second position, the second connecting electrode 72 is aligned with and abuts against the power supply electrode 6 or the second power supply electrode 62, thereby establishing an electrical connection between the second connecting electrode 72 and the power supply electrode 6 or the second power supply electrode 62. When the bracket 3 is in the first position, the second connecting electrode 72 is offset from the power supply electrode 6 or the second power supply electrode 62, thereby disconnecting the electrical connection between the second connecting electrode 72 and the power supply electrode 6 or the second power supply electrode 62.

[0120] In some embodiments, reference may be made to Figure 6 and Figure 7 The bracket 3 includes a first bracket 31 for connecting the first atomizer 21 and a second bracket 32 ​​for connecting the second atomizer 22. The first bracket 31 and the second bracket 32 ​​are connected to each other and have a cavity 34 between them. The first power-taking electrode 81 is held on the first bracket 31 and is electrically connected to the first connecting electrode 71 in the cavity 34.

[0121] For example, not shown, the aerosol generating device includes an integrally formed conductive element, which includes a first power-taking electrode and a first connecting electrode, with a portion of the conductive element disposed within the cavity. The first power-taking electrode and the first connecting electrode may be disposed at opposite ends of the conductive element.

[0122] For example, you can refer to Figure 6 The first power-taking electrode 81 and the first connecting electrode 71 are independent of each other, so that the first power-taking electrode 81 can be independently held on the bracket 3, and the first connecting electrode 71 can be independently held on the retainer 33. The first power-taking electrode 81 and the first connecting electrode 71 can be electrically connected by a conductive element (not shown), which includes, but is not limited to, a wire or a metal piece, so that the conductive element is located in the cavity 34. Alternatively, the first power-taking electrode 81 and the first connecting electrode 71 can be electrically connected by welding or abutting against each other, so that a portion of the first power-taking electrode 81 and / or a portion of the first connecting electrode 71 is located in the cavity 34.

[0123] In some embodiments, reference may be made to Figure 6 and Figure 8 The retainer 33 connects both the first bracket 31 and the second bracket 32. Furthermore, there is a receiving area between the first bracket 31 and the second bracket 32, and the retainer 33 is held within this receiving area, such that at least a portion of the retainer 33 is located between the first bracket 31 and the second bracket 32. Preferably, the surfaces of the first bracket 31, the second bracket 32, and the retainer 33 facing the partition plate 5 are all substantially planar, and the surfaces of all three facing the partition plate 5 are substantially flush.

[0124] In some embodiments, reference may be made to Figure 2 and Figure 5 The aerosol generating device 100 includes a first opening 911 and a first cover 1a disposed near the proximal end of the housing 1. The nozzle 25 of the first atomizer 21 is configured to extend from the first opening 911 when the support 3 is in a first position and retract into the housing 1 when the support 3 is in a second position. The first cover 1a is configured to cover the first opening 911 after the nozzle 25 of the first atomizer 21 is retracted into the housing 1, thereby preventing solid substances or particles from falling into the nozzle 25 of the first atomizer 21 or into the air inlet 251 of the first atomizer 21.

[0125] Furthermore, the aerosol generating device 100 includes a first end cap 91 disposed near the end of the housing 1, a first opening 911 being provided on the first end cap 91, a first shielding cover 1a being movably connected to the first end cap 91 or the housing 1, and when the support 3 is in the first position, the first shielding cover 1a continues to be connected to the housing 1 and / or the first end cap 91, and the first shielding cover 1a is offset from the first opening 911.

[0126] For example, the first cover 1a is configured to slide laterally relative to the first end cap 91 and the housing 1. The first cover 1a can be slid to cover or open the first opening 911. When it is necessary to change the first atomizer 21 from an unusable state to a usable state, the first cover 1a can be moved laterally first to open the first opening 911, and then the bracket 3 can be moved to the first position so that the nozzle 25 of the first atomizer 21 passes through the first opening 911, thereby protruding from the first opening 911 and the housing 1.

[0127] Alternatively, for example, the first cover 1a is configured to rotate relative to the first end cap 91 and the housing 1, and the first cover 1a can be rotated to cover or open the first opening 911.

[0128] Furthermore, the proximal and distal ends of the housing 1 are located at opposite ends of the housing 1 in the longitudinal direction. The first shielding cover 1a is configured such that the axis of rotation for rotation relative to the first end cover 91 and the housing 1 extends laterally, with the lateral direction being perpendicular to the longitudinal direction. When the first shielding cover 1a covers the first opening 911, the first surface of the first shielding cover 1a faces the distal end of the housing 1. During the movement of the support 3 from the second position to the first position, the nozzle 25 of the first atomizer 21 gradually pushes up the first shielding cover 1a until the first shielding cover 1a flips over, at which point the first surface of the first shielding cover 1a faces away from the distal end of the housing 1.

[0129] In some embodiments, reference may be made to Figure 2 and Figure 5 The aerosol generating device 100 includes a second opening 921 and a second cover 2a disposed at the distal end adjacent to the housing 1. The nozzle 25 of the second atomizer 22 is configured to extend from the second opening 921 when the support 3 is in the second position and retract into the housing 1 when the support 3 is in the first position. The second cover 2a is configured to cover the second opening 921 after the nozzle 25 of the second atomizer 22 is retracted into the housing 1, thereby preventing external solid substances or particles from falling into the nozzle 25 of the second atomizer 22 or into the air inlet 251 of the second atomizer 22.

[0130] Furthermore, the aerosol generating device 100 includes a second end cap 92 disposed at the far end of the housing 1, a second opening 921 being provided on the second end cap 92, a second shielding cover 2a being movably connected to the second end cap 92 or the housing 1, and when the support 3 is in the second position, the second shielding cover 2a continues to be connected to the housing 1 and / or the second end cap 92, and the second shielding cover 2a is offset from the second opening 921.

[0131] For example, the second cover 2a is configured to slide laterally relative to the second end cap 92 and the housing 1. The second cover 2a can be slid to cover or open the second opening 921. When it is necessary to change the second atomizer 22 from an unusable state to a usable state, the second cover 2a can be moved laterally first to open the second opening 921, and then the bracket 3 can be moved to the second position so that the mouthpiece 25 of the second atomizer 22 passes through the second opening 921, thereby protruding from the second opening 921 and the housing 1.

[0132] Alternatively, for example, the second cover 2a is configured to rotate relative to the second end cover 92 and the housing 1, and the second cover 2a can be rotated to cover or open the second opening 921.

[0133] Furthermore, the proximal and distal ends of the housing 1 are located at opposite ends of the housing 1 in the longitudinal direction. The second shielding cover 2a is configured such that the axis of rotation of the housing 1 relative to the second end cover 92 extends laterally, with the lateral direction being perpendicular to the longitudinal direction. When the second shielding cover 2a covers the second opening 921, the second surface of the second shielding cover 2a faces the proximal end of the housing 1. During the movement of the support 3 from the first position to the second position, the nozzle 25 of the second atomizer 22 gradually pushes up the second shielding cover 2a until the second shielding cover 2a flips over, at which point the second surface of the second shielding cover 2a faces away from the proximal end of the housing 1.

[0134] In some embodiments, reference may be made to Figure 1 The aerosol generating device 100 further includes an operating member 3a, which is at least partially exposed and thus operable. The operating member 3a is linked to the support 3, thereby driving the support 3 to move between a first position and a second position. Preferably, the operating member 3a is configured to drive the support 3 to move along a linear trajectory between the first position and the second position.

[0135] In some embodiments, reference may be made to Figure 1 The housing 1 has a relief groove 11, at least a portion of which corresponds to the operating member. At least a portion of the operating member 3a is located in the relief groove 11 and thus exposed. The operating member 3a is configured to move in the relief groove 11.

[0136] Furthermore, the clearance groove 11 includes a linear groove 111, and the operating member 3a can be operated to move along the extension direction of the linear groove 111. Even further, the linear groove 111 extends in a straight line, so that the operating member 3a can move linearly along the linear groove 111, thereby driving the support 3 to move between a first position and a second position. Preferably, the movement trajectory of the operating member 3a is parallel to the movement trajectory of the support 3, and the operating member 3a and the support 3 are configured to move synchronously in the same direction. More preferably, the operating member 3a is connected to the support 3. For example, the first support 31 and the second support 32 are interconnected, and the operating member 3a is connected to either the first support 31 or the second support 32.

[0137] Of course, in other embodiments, the operating member 3a may be configured to rotate in the relief groove 11 to drive the bracket 3 to make linear motion between the first position and the second position, or to drive the bracket 3 to rotate between the first position and the second position.

[0138] In some embodiments, reference may be made to Figure 7 There are two operating members 3a, both of which are connected to the bracket 3. Correspondingly, two clearance grooves 11 are formed on the housing 1, and the two operating members 3a can move in the two clearance grooves 11 respectively. Moreover, the bracket 3 can be driven to move between a first position and a second position by operating either operating member 3a. Preferably, the two clearance grooves 11 are respectively provided on two opposite side walls of the housing 1.

[0139] In some embodiments, reference may be made to Figure 2 and Figure 3 The housing 1 has an air inlet 12. When the support 3 is in the first position, the air inlet 12 is connected to the first atomizer 21. This allows outside air to enter the first atomizer 21 through the air inlet 12 when the user inhales through the mouthpiece 25 of the first atomizer 21. The air inlet combines with volatiles generated by the aerosol-generating matrix in the first atomizer 21 to form an aerosol, which then flows out through the mouthpiece 25. When the support 3 is in the second position, the air inlet 12 is connected to the second atomizer 22. This allows outside air to enter the second atomizer 25 through the air inlet 12 when the user inhales through the mouthpiece 25 of the second atomizer 22. The air inlet combines with volatiles generated by the aerosol-generating matrix in the second atomizer 25 to form an aerosol, which then flows out through the mouthpiece 25.

[0140] In some embodiments (not shown), the air intake includes a common air intake, and the first atomizer and the second atomizer are configured to share the common air intake. When the bracket is in a first position, the common air intake communicates with the first atomizer, and when the bracket is in a second position, the common air intake communicates with the second atomizer.

[0141] In some embodiments, reference may be made to Figure 2 and Figure 3 The air inlet 12 includes a first air inlet 121 and a second air inlet 122 independent of the first air inlet 121. When the bracket 3 is in the first position, the first air inlet 121 is connected to the first atomizer 21, so that outside air can enter the first atomizer 21 through the first air inlet 121. When the bracket 3 is in the second position, the second air inlet 122 is connected to the second atomizer 22, so that outside air can enter the second atomizer 22 through the second air inlet 122.

[0142] The first air inlet 121 and the second air inlet 122 can have the same ventilation cross-sectional area, so that under the same suction force, the first air inlet 121 and the second air inlet 122 have the same air intake volume in the same amount of time. The first air inlet 121 and the second air inlet 122 can also have different ventilation cross-sectional areas. The first air inlet 121 and the second air inlet 122 can have the same number. The first air inlet 121 and the second air inlet 122 can also have different numbers.

[0143] In some embodiments, reference may be made to Figure 2 and Figure 3 The bracket 3 is provided with a first connecting hole 312 for connecting the first atomizer 21 and a second connecting hole 322 for connecting the second atomizer 22. The second connecting hole 322 is independent of the first connecting hole 312. When the bracket 3 is in the first position, the housing 1 covers the second connecting hole 322, making the second connecting hole 322 hidden, and the air inlet 12 is connected to the first connecting hole 312. When the bracket 3 is in the second position, the housing 1 covers the first connecting hole 312, making the first connecting hole 312 hidden, and the air inlet 12 is connected to the second connecting hole 322.

[0144] The first connecting hole 312 and the second connecting hole 322 may have the same ventilation cross-sectional area. Alternatively, the first connecting hole 312 and the second connecting hole 322 may have different ventilation cross-sectional areas. The first connecting hole 312 and the second connecting hole 322 may have the same number. Alternatively, the first connecting hole 312 and the second connecting hole 322 may have different numbers.

[0145] Furthermore, the first connecting hole 312 can maintain communication with the first receiving cavity 311, or when the first atomizer 21 is connected to the bracket 3, the first connecting hole 312 can maintain communication with the first atomizer 21.

[0146] And / or, the second communication hole 322 can maintain communication with the second receiving cavity 321, or when the second atomizer 22 is connected to the bracket 3, the second communication hole 322 can maintain communication with the second atomizer 22.

[0147] In some embodiments, reference may be made to Figure 2 and Figure 7 A first sealing element 313 is provided on the bracket 3 and / or the housing 1. The first sealing element 313 is provided corresponding to the first connecting hole 312 to provide a seal between the air inlet 12 and the first connecting hole 312 when the bracket 3 is in the second position, so that the air inlet 12 is isolated from the first connecting hole 312 to prevent outside air from entering the first atomizer 21 through the air inlet 12.

[0148] Furthermore, when the bracket 3 is in the first position, the first seal 313 sealably connects the first air inlet 121 and the first connecting hole 312, so that the air entering the first air inlet 121 can enter the first connecting hole 312 without leakage, and helps to prevent the air entering through the second air inlet 122 from entering the first connecting hole 312.

[0149] Preferably, the first seal 313 is disposed on the first bracket 31.

[0150] In some embodiments, reference may be made to Figure 2 and Figure 7 A second seal 323 is provided on the bracket 3 and / or the housing 1. The second seal 323 is provided corresponding to the second connecting hole 322 to provide a seal between the air inlet 12 and the second connecting hole 322 when the bracket 3 is in the first position, so that the air inlet 12 is isolated from the second connecting hole 322 to prevent outside air from entering the second atomizer 22 through the air inlet 12.

[0151] Furthermore, when the bracket 3 is in the second position, the second seal 323 sealably connects the second air inlet 122 and the second connecting hole 322, so that the air entering the second air inlet 122 can enter the second connecting hole 322 without leakage, and helps to prevent the air entering through the first air inlet 121 from entering the second connecting hole 322.

[0152] Preferably, the second seal 323 is disposed on the second bracket 32.

[0153] In some embodiments, when the bracket 3 is in the second position, the air passage between the first atomizer 21 and the first air inlet 121 is disconnected under the action of the first seal 313. Further, when the bracket 3 is in the first position, the air passage between the second atomizer 22 and the second air inlet 122 is disconnected under the action of the second seal 323.

[0154] In some embodiments, the bracket 3 is configured to be movable to a third position. When the bracket 3 is in the third position, the air inlet 12 is isolated from the airflow of both the first atomizer 21 and the second atomizer 22, so that outside air cannot enter the first atomizer 21 through the air inlet 12, nor can it enter the second atomizer 22 through the air inlet 12.

[0155] When the atomizer 2 is inhaled through the mouthpiece 25, the airflow within the atomizer 2 changes. This airflow change includes, but is not limited to, a change in at least one of the following: air pressure, airflow velocity, or airflow direction. The airflow sensor 4a is a sensor capable of sensing airflow changes when the airflow change reaches a threshold value, at least one of its electrical parameters changes. Furthermore, the airflow sensor 4a can generate a control signal based on its sensing result.

[0156] In some embodiments, reference may be made to Figure 2 The aerosol generating device 100 also includes an airflow sensor 4a, which is configured to communicate with the first atomizer 21 when the support 3 is in the first position to sense changes in airflow in the first atomizer 21. The controller can then control the power supply 4 to provide electrical power to the first atomizer 21 based on the sensing result. When the support 3 is in the second position, the atomizer 22 is connected to sense changes in airflow in the second atomizer 22. The controller can then control the power supply 4 to provide electrical power to the second atomizer 22 based on the sensing result.

[0157] In some embodiments (not shown), the airflow sensor includes a common airflow sensor, wherein a first atomizer and a second atomizer are configured to share the common airflow sensor. When the support is in a first position, the common airflow sensor is connected only to the first atomizer of the first atomizer and the second atomizer. When the support is in a second position, the common airflow sensor is connected to the second atomizer of the first atomizer and the second atomizer.

[0158] In some embodiments, reference may be made to Figure 2 The airflow sensor 4a includes a first airflow sensor 4a1 and a second airflow sensor 4a2, independent of the first airflow sensor 4a1. When the bracket 3 is in the first position, the first airflow sensor 4a1 is connected to the first atomizer 21, so that the first airflow sensor 4a1 can sense changes in airflow in the first atomizer 21, and the controller can then control the power supply 4 to provide electrical power to the first atomizer 21 based on the sensing result. When the bracket 3 is in the second position, the second airflow sensor 4a2 is connected to the second atomizer 22, so that the second airflow sensor 4a2 can sense changes in airflow in the second atomizer 22, and the controller can then control the power supply 4 to provide electrical power to the second atomizer 22 based on the sensing result.

[0159] In some embodiments, reference may be made to Figure 2 and Figure 4 The bracket 3 is provided with a third connecting hole 314 for connecting the first atomizer 21 and a fourth connecting hole 324 for connecting the second atomizer 22. The third connecting hole 314 is independent of the fourth connecting hole 324.

[0160] When the support 3 is in the first position, the airflow sensor 4a connects to the third connecting hole 314, and thus connects to the first atomizer 21; for example, when the support 3 is in the first position, the first airflow sensor 4a1 corresponds to and connects to the third connecting hole 314, thus the first airflow sensor 4a1 connects to the first atomizer 21. When drawing air into the mouthpiece 25 of the first atomizer 21, the gas near the sensing part of the first airflow sensor 4a1 flows to the mouthpiece 25 of the first atomizer 21 through the third connecting hole 314, thereby causing a change in the airflow near the sensing part of the first airflow sensor 4a1, such as the appearance of negative pressure. Based on this, the first airflow sensor 4a1 senses the change in airflow in the first atomizer 21, and then causes the controller to control the power supply 4 to provide electrical power to the first atomizer 21.

[0161] When the support is in the second position, the airflow sensor 4a connects to the fourth connecting hole 324, and thus connects to the second atomizer 22. For example, when the support 3 is in the second position, the second airflow sensor 4a2 corresponds to and connects to the fourth connecting hole 324, thus connecting the second airflow sensor 4a2 to the second atomizer 22. When drawing air into the mouthpiece 25 of the second atomizer 22, the gas near the sensing part of the second airflow sensor 4a2 flows to the mouthpiece 25 of the second atomizer 22 through the fourth connecting hole 324, causing a change in the airflow near the sensing part of the second airflow sensor 4a2, such as the appearance of negative pressure. Based on this, the second airflow sensor 4a2 senses the change in airflow in the second atomizer 22, and then causes the controller to control the power supply 4 to provide electrical power to the second atomizer 22.

[0162] In some embodiments, reference may be made to Figure 2 The partition plate 5 is disposed between the bracket 3 and the airflow sensor 4a, and the partition plate 5 is provided with a through hole 51 that connects to the airflow sensor 4a. When the bracket 3 is in the first position, the through hole 51 connects to the third through hole 314; when the bracket 3 is in the second position, the through hole 51 connects to the fourth through hole 324.

[0163] Furthermore, the through-hole 51 includes a first through-hole 511 that communicates with the first airflow sensor 4a1 and a second through-hole 512 that communicates with the second airflow sensor 4a2, wherein the first through-hole 511 is independent of the second through-hole 512. When the bracket 3 is in the first position, the first through-hole 511 communicates with the third through-hole 314; when the bracket 3 is in the second position, the second through-hole 512 communicates with the fourth through-hole 324.

[0164] In some embodiments, reference may be made to Figure 2 A third seal 52 is provided on the partition plate 5 and / or the bracket 3. The third seal 52 is provided corresponding to the third connecting hole 314 so as to seal the connection between the through hole 51 and the third connecting hole 314 when the bracket 3 is in the first position. This prevents the gas in the second atomizer 22 from entering the third connecting hole 314 through the fourth connecting hole 324 and prevents the gas in other parts of the housing 1 from entering the third connecting hole 314. This helps to improve the sensing sensitivity and accuracy of the airflow sensor 4a.

[0165] Furthermore, when the bracket 3 is in the first position, the third seal 53 seals the first through hole 511 and the third through hole 314, and isolates the first through hole 511 and the second through hole 512, which helps to prevent changes in airflow near the sensing part of the second airflow sensor 4a2, and also helps to improve the sensing sensitivity and accuracy of the first airflow sensor 4a1.

[0166] Preferably, the third seal 52 is disposed on the first bracket 31.

[0167] In some embodiments, reference may be made to Figure 2 A fourth sealing element 53 is provided on the partition plate 5 and / or the bracket 3. The fourth sealing element 53 is provided corresponding to the fourth connecting hole 324 so as to seal the connection between the through hole 51 and the fourth connecting hole 324 when the bracket 3 is in the second position. This prevents the gas in the first atomizer 21 from entering the fourth connecting hole 324 through the third connecting hole 314 and prevents the gas in other parts of the housing 1 from entering the fourth connecting hole 324, which helps to improve the sensing sensitivity and accuracy of the airflow sensor 4a.

[0168] Furthermore, when the bracket 3 is in the first position, the fourth seal 53 seals the second through hole 512 and the fourth through hole 324, and isolates the first through hole 511 and the second through hole 512, which helps to prevent changes in airflow near the sensing part of the first airflow sensor 4a1, and also helps to improve the sensing sensitivity and accuracy of the second airflow sensor 4a2.

[0169] Preferably, the fourth seal 53 is disposed on the second bracket 32.

[0170] In some embodiments, when the bracket 3 is in the second position, the air path between the first atomizer 21 and the first airflow sensor 4a1 is disconnected under the action of the third seal 52 and / or the fourth seal 53. Further, when the bracket 3 is in the first position, the air path between the second atomizer 22 and the second airflow sensor 4a2 is disconnected under the action of the third seal 52 and / or the fourth seal 53.

[0171] In some embodiments, reference may be made to Figure 3and Figure 7 One of the partition plate 5 and the bracket 3 is provided with a longitudinally extending guide rail 54, and the other is provided with a sliding part 35. The sliding part 35 is slidably connected to the guide rail 54, allowing the sliding part 35 to slide longitudinally along the guide rail 54, thereby allowing the bracket 3 to slide longitudinally relative to the partition plate 5. The sliding engagement between the sliding part 35 and the guide rail 54 helps the bracket 3 to move more smoothly between the first and second positions. Figure 3 In the illustrated embodiment, the guide rail 54 is disposed on the partition plate 5, and further, the guide rail 54 and the partition plate 5 are integrally formed. In such a case... Figure 7 In the embodiment shown, both the first bracket 31 and the second bracket 32 ​​are provided with sliding parts 35, so that both the first bracket 31 and the second bracket 32 ​​can be slidably connected to the guide rail 54.

[0172] 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.
