[0041] Please refer to Figure 1-Figure 3 One embodiment of the present application provides an aerosol generating device, the aerosol generating device comprises a first assembly 2 and a second assembly 1, wherein the second assembly 1 comprises a plurality of atomizers 11, and as shown in the present application, "plurality" means two or more. Figure 2 In the illustrated embodiment, the second assembly 1 includes four atomizers 11 in total, and the four atomizers 11 are arranged in an array.

[0042] At least two of the multiple atomizers 11 can be used to contain different liquid matrices, including liquid matrices with different flavors or liquid matrices with different ingredients and proportions. Of course, in some embodiments, all the atomizers 11 can contain the same liquid matrix.

[0043] Wherein, liquid matrix can comprise the liquid containing tobacco substance containing volatile tobacco flavor component, can also be the liquid comprising non-tobacco substance.Liquid matrix can comprise water, liquid medicine, solvent, ethanol, plant extract, spices, flavoring agent or vitamin mixture etc., and spices can comprise betel nut extract, menthol, European mint, green mint oil, various fruity fragrance components etc., but is not limited to this.Flavoring agent can comprise the composition that can provide various fragrance or local flavor to the user.Vitamin mixture can be the mixture that is mixed with at least one in vitamin A, vitamin B, vitamin C and vitamin E, but is not limited to this.Based on the different attributes of liquid matrix, aerosol generating device can be used for different fields, such as, medical treatment, electronic aerosol atomization etc.

[0044] The atomizer 11 includes a liquid cup 111 for accommodating a liquid matrix and an atomizing core 112 in fluid communication with the liquid cup 111. The atomizing core 112 is used to atomize the liquid matrix so that the liquid matrix produces an aerosol. The atomizing core 112 may include an absorbent element and a heating element. The absorbent element may be a porous body or fiber, capable of absorbing the liquid matrix and capable of guiding the liquid matrix into the atomization range of the heating element; the heating element is used to atomize at least part of the liquid matrix on the absorbent element to form an aerosol. The heating element may be combined with the absorbent element so that the heating element can form a whole with the heating element. In some embodiments, the liquid cup 111 has a liquid storage cotton, and the liquid matrix is ​​adsorbed in the liquid storage cotton and thus retained in the liquid cup 111. Of course, the liquid storage cotton is optional and not mandatory.

[0045] At least a portion of the wall of the liquid cup 111 may be transparent, so that a user can observe the remaining amount of the liquid matrix inside the liquid cup 111 through the wall of the liquid cup 111 .

[0046] The second assembly 1 may further include a second housing 13, wherein the plurality of atomizers 11 are accommodated in the second housing 13, wherein at least a portion of the second housing 13 has a window 131, wherein the window 131 is transparent, so that the liquid cup 111 can be visually observed through the window 131. When at least a portion of the wall of the liquid cup 111 is transparent, the remaining amount of the liquid matrix in the liquid cup 111 can be visually observed through the second housing 13 and the liquid cup 111 in sequence. The window 131 may have one or more windows. Figure 1 In the illustrated embodiment, there are a plurality of viewing windows 131 , and the plurality of viewing windows 131 correspond one-to-one to the plurality of atomizers 11 , so that the remaining amount of liquid matrix in different atomizers 11 can be observed through different viewing windows 131 .

[0047] Each of the above-mentioned atomizers 11 may also include a first air channel 113, the first air channel 113 is in fluid communication with the atomizer core 112, and the first air channel 113 is used to transmit aerosol. In one example, the atomizer 11 may have an atomization compartment in fluid communication with the liquid cup 111, the atomization core 112 is accommodated in the atomization compartment, and the first channel 113 is in fluid communication with the atomization compartment; alternatively, reference may be made to Figure 2 In another example, at least a portion of the atomizer core 112 is arranged in the first channel 113 .

[0048] Each of the above-mentioned atomizers 11 may also include a second electrode group 114. The heating element generates heat by drawing electricity from the second electrode group 114. The second electrode group 114 may include a positive output electrode and a negative output electrode. The positive output electrode and the negative output electrode may be electrically connected to the opposite ends of the heating element respectively.

[0049] You can refer to Figure 1 and Figure 2The aerosol generating device further comprises a mouthpiece 3, which can be selectively connected to the first air passage 113 fluid in any atomizer 11 in the second assembly 1, or the mouthpiece 3 can be simultaneously connected to the first air passage 113 fluid in multiple atomizers 11. At least a part of the mouthpiece 3 can be held in the mouth of the user, so that the user can inhale the aerosol generated by the atomizer by sucking the mouthpiece 3.

[0050] The aerosol generating device further includes a power supply assembly, which includes a first electrode group 4, and the first electrode group 4 is used to be electrically connected to at least one atomizer 11 in the second assembly 1. The first electrode group 4 is electrically connected to the second electrode group 114 of the atomizer 11 to be electrically connected to the atomizer 11. The electrical connection between the first electrode group 4 and the second electrode group 114 can be abutment, and the abutment between the first electrode group 4 and the second electrode group 114 can be elastic abutment. The electrodes in the first electrode group 4 can include a positive output electrode and a negative output electrode, and the positive output electrode and the negative output electrode in the first electrode group 4 are respectively used to be electrically connected to the positive output electrode and the negative output electrode in the second electrode group 114 of the atomizer 11.

[0051] The power supply assembly may further include a battery cell, which may be any suitable battery, and the battery cell may provide power to the atomizer 11 electrically connected to the first electrode group 4 through the first electrode group 4, and the positive output electrode and the negative output electrode in the first electrode group 4 may be electrically connected to the positive output end and the negative output end of the battery cell 41, respectively. The power supply assembly may further include a circuit board, and the circuit board may electrically connect the battery cell and the first electrode group 4. When the first electrode group 4 is electrically connected to at least one atomizer 11 in the second assembly 1, the circuit board may control the battery cell to provide power to the first electrode group 4, thereby enabling the atomizer core 112 in the atomizer 11 electrically connected to the first electrode group 4 to obtain power and atomize the liquid matrix.

[0052] The first assembly 2 and the second assembly 1 are rotatably connected around an axis in the first direction, and the relative position relationship between the plurality of atomizers 11 in the second assembly 1 and the first assembly 2 can be changed by rotation. For example, the atomizer 11 in the non-working position is rotated to the working position by rotation, and the atomizer 11 in the working position is the atomizer selected by operation. In some examples, the atomizer selected by operation can be activated, and then can generate aerosol for the user to inhale or use.

[0053] When the liquid matrix in the atomizer 11 at the working position is exhausted, a new atomizer 11 with sufficient liquid matrix can be rotated to replace the atomizer 11 with exhausted liquid matrix in the working position. Alternatively, when there is a need to change the smoking taste, an atomizer 11 with another flavor can be rotated to replace the original atomizer 11 in the working position. It should be noted that the working position can be occupied by only one atomizer 11 at the same time; or the working position can accommodate two or more atomizers 11 at the same time, so that the user can inhale the aerosol generated by multiple atomizers 11 at the same time.

[0054] In one embodiment, reference may be made to Figure 1 and Figure 2 The second housing 13 of the second assembly 1 has a viewing window 131, and at least a portion of the liquid cup 111 of the atomizer 11 is transparent, so that the user can observe the remaining amount of the liquid matrix in the liquid cup 11. The user can determine whether to switch the atomizer 11 in the working position based on the remaining amount of the liquid matrix in the atomizer 11.

[0055] In order to facilitate the user to determine whether one or more atomizers 11 in the second assembly 1 are rotated to the working position, or to determine whether one or more atomizers 11 in the second assembly 1 are rotated to become the atomizer selected by the operation, the first assembly 2 includes a first feedback member 22, and the second assembly 1 includes a second feedback member 14. During the relative rotation of the first assembly 2 and the second assembly 1 around the axis of the first direction, the relative position of the first feedback member 22 and the second feedback member 14 can change, and at least one of the first feedback member 22 and the second feedback member 14 can be elastically deformed in the second direction, and when the positions of the first feedback member 22 and the second feedback member 14 are relatively punctual, feedback can be provided to the user through the elastic deformation to prompt that at least one atomizer 11 in the second assembly 1 is selected by the operation. For example, during the relative rotation of the first assembly 2 and the second assembly 1, the deformation amount of the elastic deformation changes relatively punctually between the first feedback member 22 and the second feedback member 114, thereby providing the user with feedback that at least one atomizer 11 in the second assembly 1 is selected by the operation or can be activated.

[0056] The second direction is perpendicular to the first direction. The mouthpiece 3 and the second assembly 1 are arranged in the first direction, and / or the atomizer 11 in the second assembly 1 and the first assembly 2 are arranged in the first direction. The multiple atomizers 11 in the second assembly 1 are arranged relative to each other in the second direction.

[0057] In one embodiment, a change in the deformation amount of the elastic deformation may cause a change in the electrical parameters of a detector or a capacitor in the aerosol generating device. The controller on the circuit board may control a buzzer or a player to produce an auditory prompt, and / or a motor or a vibrator to produce a tactile prompt, and / or an LED light or a display to produce a visual prompt based on the change in the electrical parameters. The auditory prompt, tactile prompt and / or visual prompt are used as feedback that at least one atomizer 11 in the second assembly 1 has been selected or can be started, so as to prompt the user to perceive that the second assembly 1 can stop rotating relative to the first assembly 2.

[0058] In one embodiment, when the positions of the first feedback member 22 and the second feedback member 114 are relatively aligned, the amount of elastic deformation causes collisions between other components in the aerosol generating device, thereby causing at least part of the aerosol generating device to vibrate and / or emit sounds. Vibration and / or sound are used as feedback that at least one atomizer 11 in the second assembly 114 is selected or can be activated, so as to prompt the user to perceive that the second assembly 1 stops rotating relative to the first assembly 2.

[0059] In one embodiment, when the positions of the first feedback member 22 and the second feedback member 114 are relatively aligned, the first feedback member 22 and the second feedback member 114 interfere with each other, thereby causing the deformation amount of the elastic deformation to change. As an example, the interference between the first feedback member 22 and the second feedback member 114 includes a collision between the two, thereby causing at least part of the aerosol generating device to vibrate or emit a sound, and using the vibration and / or sound as feedback that at least one atomizer 11 in the second assembly is selected or can be activated, so as to prompt the user to perceive that the second assembly 1 can stop rotating relative to the first assembly 2. As an example, the interference between the first feedback member 22 and the second feedback member 114 includes that one is at least partially embedded in the other, or the interference between the first feedback member 22 and the second feedback member 114 includes that the two have a force on each other, so that the resistance to the rotation of the second assembly 1 relative to the first assembly 2 suddenly increases, or the smoothness of the rotation of the second assembly 1 relative to the first assembly 2 changes, which can make the user have obvious tactile sensation, and use this tactile sensation as feedback that at least one atomizer 11 in the second assembly 1 has been selected or can be activated, to prompt the user to perceive that the second assembly 1 can stop rotating relative to the first assembly 2.

[0060] In one embodiment, the first assembly 2 includes a first retaining member 21, and the second assembly 1 includes a second retaining member 12. One of the first retaining member 21 and the second retaining member 12 includes an annular wall 121, and the other includes a protrusion 211, and the annular wall 121 surrounds at least a portion of the periphery of the protrusion 211; one of the first feedback member 22 and the second feedback member 14 includes a groove 141 arranged on the inner side of the annular wall 121, and the other includes an embedded portion 221 at least partially exposed on the outer side of the protrusion 211; when the first feedback member corresponds to the second feedback member, at least a portion of the embedded portion 221 is located in the groove 141.

[0061] Furthermore, when at least a portion of the embedded portion 221 is located in the groove 141, the groove 141 provides a clearance space, so that the extrusion force on at least one of the first feedback member 22 and the second feedback member 14 in the second direction is reduced, and at least part of the elastic potential energy can be released, thereby changing the deformation amount of the elastic deformation.

[0062] When the first assembly 2 and the second assembly 1 continue to rotate relative to each other around the axis in the first direction so that the first feedback member 22 and the second feedback member 14 are offset from each other, the embedded portion 221 disengages from the groove 141, so that the extrusion force in the second direction on at least one of the first feedback member 22 and the second feedback member 14 is restored and has a larger elastic potential energy again, so that the deformation amount of the elastic deformation changes again when the embedded portion 221 disengages from the groove 141.

[0063] For example, when at least one of the first feedback member 22 and the second feedback member 14 releases elastic potential energy in the second direction, the embedded portion 221 collides with the groove 141 , thereby generating the above feedback.

[0064] For example, when at least one of the first feedback member 22 and the second feedback member 14 releases elastic potential energy in the second direction, at least a portion of the embedded portion 221 is located in the groove 141, and the resistance to the rotation of the second assembly 1 relative to the first assembly 2 suddenly increases, or the smoothness of the rotation of the second assembly 1 relative to the first assembly 2 changes, thereby generating the above-mentioned feedback.

[0065] In one embodiment, reference may be made to Figure 3 and Figure 4The annular wall 121 has an open first end 1211, and the first end 1211 is used for the protrusion 211 to be inserted into the annular wall 121, so that at least a portion of the protrusion 211 is surrounded by the annular wall 121. The groove 141 includes a wire groove, which extends to the first end 1211 or extends to the vicinity of the first end 1211. During the process of at least a portion of the protrusion 211 being inserted into the annular wall 121, the embedded portion 221 slides along the groove 141. Because the groove 141 can provide a clearance space, during the process of at least a portion of the protrusion 211 being inserted into the annular wall 121, the embedded portion 221 slides along the groove 141, which can reduce the resistance of the protrusion 211 to be inserted into the annular wall 121, and helps the protrusion 211 to be combined with the annular wall 121. In addition, the groove 141 has a guiding function, which can guide the protrusion 211 to enter the annular wall 121.

[0066] In order to facilitate the insertion of the protrusion 211 into the annular wall 121, the inner side surface of the annular wall 121 may include a guiding bevel 1212. The guiding bevel 1212 is arranged adjacent to the first end 1211. Along the direction in which the protrusion 211 is inserted into the annular wall 121, the guiding bevel 1212 gradually converges, thereby gradually reducing its size. Therefore, the starting end of the guiding bevel 1212 has a larger size, and preferably the size of the starting end of the guiding bevel 1212 is larger than the size of the head end of the protrusion 211. The groove 141 can extend to the guiding bevel 1212, and the end of the groove 141 can be critically arranged with the guiding bevel 1212. The groove 141 and the first end 1211 of the annular wall 121 are separated by the guiding bevel 1212. Figure 3 and Figure 4 In the embodiment, the end of the groove 131 is located on the guiding slope 1212 , so that the groove 141 does not extend to the first end 1211 of the annular wall 121 .

[0067] Since the groove 141 is disposed on the inner side of the annular wall 121, it is concealed, especially when the groove 141 does not extend to the first end 1211. In order to facilitate the combination of the protruding portion 211 and the annular wall 121, the embedded portion 221 can be aligned with the groove 141 so that it can fall into the groove 141 accurately, and then move along the groove 141. Figure 1In the illustrated embodiment, the first assembly 2 has a first alignment mark 23 that is at least partially exposed, the second assembly 1 has a second alignment mark 15 that is at least partially exposed, the groove 141 or the wire groove is linear and extends along the first direction, or the extension direction is substantially parallel to the first direction, and when the first alignment mark 23 is aligned with the second alignment mark 15, the embedded portion 221 and the groove 141 or the wire groove are located on the same straight line extending along the first direction, or the embedded portion 221 falls into the groove 141 or the wire groove. Therefore, in the process of combining the protruding portion 221 with the annular wall 121, as long as the first alignment mark 23 exposed to the outside and the second alignment mark 15 exposed to the outside are aligned with each other, it can be ensured that the embedded portion 221 can accurately fall into the groove 141, and then move along the groove 141, so that the protruding portion 221 enters the annular wall 121, and the two are combined.

[0068] exist Figure 4 and Figure 5 In the illustrated embodiment, the first retaining member 21 is at least partially exposed and provided with a first alignment mark 23, and the second retaining member 12 is at least partially exposed and provided with a second alignment mark 15. At least one of the first alignment mark 23 and the second alignment mark 15 can be a color bar, a color block, text, an icon, a bump or a groove.

[0069] As an example, the embedded portion 221 includes a spherical ball, and during the relative rotation of the first assembly 2 and the second assembly 1, the spherical ball is rollingly connected with the inner side of the annular wall 121, which is beneficial to reduce the resistance of the relative rotation of the first assembly 2 and the second assembly 1. The spherical ball can be made of metal or have a smooth surface.

[0070] In the first preferred embodiment of the present application, reference can be made to Figure 5 and Figure 6 , the first electrode group 4 is fixed on the first holding member 21, so that when the first assembly 2 and the second assembly 1 rotate relative to each other around the axis of the first direction, the second assembly 1 can rotate relative to the first electrode group 4, and when the first feedback member 22 and the second feedback member 14 are aligned relative to each other, the first electrode group 4 is only electrically connected to one of the atomizers 11, so that the atomizer 11 is selected for operation. Therefore, by making the first assembly 2 and the second assembly 1 rotate relative to each other, the first electrode group 4 can be selectively electrically connected to only one of the atomizers 11. In this embodiment, the second holding member 12 can be arranged between the mouthpiece 3 and the first holding member 21.

[0071] As an example of the first preferred embodiment, reference can be made to Figure 2, the mouthpiece 3 can rotate relative to the second assembly 1, and the mouthpiece 3 can selectively communicate with one of the atomizers 11 in fluid communication. When the mouthpiece 3 is in fluid communication with one of the atomizers 11, the user can inhale the aerosol generated by the atomizer 11 through the mouthpiece 3. The aerosol generating device also includes a connecting shaft 5, which connects the mouthpiece 3 and the first assembly 2 to link the mouthpiece 3 and the first assembly 2, so that under the connection of the connecting shaft 5, the mouthpiece 3 and the first assembly 2 can rotate synchronously relative to the second assembly 1. When the first feedback member 22 is aligned with the second feedback member 14, the mouthpiece 3 is in fluid communication with the atomizer 11 while the first electrode group 4 is electrically connected to only one of the atomizers 11.

[0072] As an example of the first preferred embodiment, reference can be made to Figure 2-Figure 4 , the second holder 12 holds and supports the atomizer 11, and holds the plurality of atomizers 11 in the second shell 13. Specifically, at least a portion of the second holder 12 is disposed in the second shell 13, and the second holder 12 supports the plurality of atomizers 11, so that the plurality of atomizers 11 are held in the second shell 13. The second holder 12 may include one or more partitions 122, and the one or more partitions 122 divide the internal space of the second shell 13 into a plurality of holding spaces, each of which may hold an atomizer 11. The outer end of the holding space defined by the second holder 12 may be open, which can reduce the volume of the aerosol generating device on the one hand, and reduce the manufacturing cost of the second holder 12 on the other hand, and at the same time, it can visually not block the second shell 13 and the liquid cup 11, which is conducive to the user observing the remaining amount of the liquid matrix in the liquid cup 11.

[0073] For further information, please refer to Figure 3 and Figure 4 The second retaining member 1 includes an internally hollow central tube 123, a plurality of partitions 122 are radially arranged on the periphery of the central tube 123 and are all connected to the central tube 123, and the connecting shaft 5 connects the first retaining member 21 and the mouthpiece 3, so that the first retaining member 21 and the mouthpiece 3 can be linked and can rotate synchronously relative to the second assembly 1, so that when the first electrode group 4 is electrically connected to one of the atomizers 11, the mouthpiece 3 is fluidically connected to the atomizer 11.

[0074] Specifically, one end of the connecting shaft 5 is connected to the first retaining member 21 , and the other end passes through the central tube 123 and is connected to the mouthpiece 3 . When the first assembly 2 and the second assembly 1 rotate relative to each other, the connecting shaft 5 rotates in the central tube 123 .

[0075] The central tube 123 and the partition plate 122 may be integrally injection molded.

[0076] As an example of the first preferred embodiment, reference can be made to Figure 2-Figure 6The first retaining member 21 includes a protruding portion 211, and the second retaining member 12 includes an annular wall 121. Since the first assembly 2 includes the first feedback member 22 and the first retaining member 21, the first feedback member 22 includes the above-mentioned embedding portion 221; similarly, the second feedback member 14 includes the above-mentioned groove 141.

[0077] In such Figure 2 and Figure 6 In the illustrated embodiment, the first feedback member 22 further includes an elastic portion 222 hidden inside the protruding portion 211 .

[0078] In such Figure 2 and Figure 6 In the illustrated embodiment, the deformation direction of the elastic portion 222 is in the same straight line with its extension direction. Specifically, the elastic portion 222 is a spring extending in the second direction, or a silicone, rubber or sponge that can be deformed in the second direction. The protrusion 211 has a receiving groove 2111 extending in the second direction inside, and at least part of the elastic portion 222 is received in the receiving groove 2111. The groove wall of the receiving groove 2111 can define the deformation direction of the elastic portion 222. When the first feedback member 22 and the second feedback member 14 are not relatively aligned, or during the relative rotation of the first assembly 2 and the second assembly 1, the elastic portion 222 elastically abuts the embedded portion 221, and the elastic portion 222 can be in an elastic compression state, with a large deformation amount, and thus has a large elastic potential energy. When the first feedback member 22 and the second feedback member 14 are relatively aligned, the elastic portion 222 pushes at least part of the embedded portion 221 into the groove 141, and the deformation amount of the elastic portion 222 is reduced, thereby releasing at least part of the elastic potential energy.

[0079] When the first feedback member 22 and the second feedback member 14 are not aligned relative to each other, or during the relative rotation of the first assembly 2 and the second assembly 1, the embedded portion 221 is at least partially accommodated in the accommodating groove 2111, and the annular wall 121 abuts against the elastic portion 222 through the embedded portion 221, so that the elastic portion 222 maintains a larger deformation amount.

[0080] When the first feedback member 22 is aligned with the second feedback member 14 , at least a portion of the embedded portion 221 is located in the groove 141 , so that the volume of the embedded portion 221 accommodated in the accommodating groove 2111 is reduced, resulting in a reduction in the deformation of the elastic portion 22 .

[0081] It should be noted that, in other examples, the elastic portion 222 may be a spring sheet connected to the side wall of the protrusion 221. The spring sheet may be a metal spring sheet, or may be integrally injection molded with the protrusion 211. The extension direction of the spring sheet intersects with its deformation direction and is not on the same straight line. For example, the extension direction of the spring sheet and its deformation direction are perpendicular to each other.

[0082] In such Figure 2-Figure 5In the illustrated embodiment, at least a portion of the first electrode group 4 may be surrounded by the annular wall 121 , for example, the first electrode group 4 may be fixed on the protrusion 211 .

An air hole 25 in fluid communication with the outside is provided on the first retaining member 21, and a hollow flexible member 24 is also fixed on the first retaining member 21, and the end of the flexible member 24 protrudes out of the first retaining member 21. When the first feedback member 22 corresponds to the second feedback member 14, the flexible member 24 elastically abuts the second assembly 1, and seals and conducts the air hole 25 and the air inlet 16 of an atomizer 11, so that the air hole 25 is only in fluid communication with the air inlet 16 of an atomizer 11, so that when the first feedback member 22 is aligned with the second feedback member 14, the air hole 25 is in fluid communication with the atomizer 11 while the first electrode group 4 is electrically connected to one of the atomizers 11.

[0084] In such Figure 5 In the illustrated embodiment, the air hole 25 is disposed on the protrusion 221 .

Therefore, by rotating the first assembly and the second assembly relative to each other, the mouthpiece can be selectively communicated with only one of the atomizer fluids. In this embodiment, the first retaining member can be arranged between the mouthpiece and the second retaining member.

[0086] As an example of the second preferred embodiment, the aerosol generating device further includes a connecting shaft and a fixing seat, the first electrode group is fixed on the fixing seat, one end of the connecting shaft is a first retaining member, and the other end passes through the second retaining member and is connected to the fixing seat, and the connecting shaft can rotate in the second retaining member, so that during the relative rotation of the first retaining member and the second retaining member, the fixing seat can rotate relative to the second retaining member, so that when the mouthpiece is in fluid communication with an atomizer, the first electrode group is electrically connected to the atomizer. The second retaining member can be located between the fixing seat and the first retaining member.

[0087] The fixing seat may also be provided with an air hole connected to an external fluid, so that when the first electrode group is electrically connected to an atomizer, the air hole is connected to the atomizer fluid.
