[0008] The external air inlet of the above multi-cartridge aerosol delivery device is located between the main body and the atomizer, which can solve the problems caused by the too long air passage of the main body in the prior art.

[0009] In some embodiments, a plurality of atomizers are provided, for example, two, that is, the corresponding number of inner shells is two, and the two inner shells are arranged side by side in the receiving cavity.

[0010] In some embodiments, the above-mentioned receiving cavity can be a complete cavity or can be divided into a plurality of independent receiving cavities. Further, the receiving cavity is spaced apart into receiving cavities that are equal in number and adapted to the number of atomizers, and each atomizer can move between a first position and a second position in the corresponding receiving cavity.

[0011] In some embodiments, the main body is provided with an operation window on the side wall of the cylinder along the axial direction of the cylinder or the longitudinal direction with height, which communicates with the receiving cavity. One end of the operation window close to the opening is used to define the first position, and the other end of the operation window defines the second position. Specifically, the aforementioned operation window can be a strip-shaped hole extending in the length direction. The atomizer is received in the receiving cavity through the opening, and the user can operate the atomizer to move between the first position and the second position in the receiving cavity through the operation window. It can be understood that after the atomizer moves to the first position, the atomizer is electrically connected to the electrical contact and can obtain power supply to atomize the aerosol-forming matrix to form an aerosol.

[0012] In some embodiments, a first air groove is provided on the inner wall of the outer shell near the second position and communicates with the operation window; when the inner shell is in the first position, the first air groove communicates with the air passage; when the inner shell is in the second position, the first air groove is blocked by the inner shell.

[0013] In some embodiments, a second air groove is provided at one end of the outer wall of the inner shell near the proximal end, and the second air groove communicates with the air passage; when the inner shell is in the first position, at least part of the second air groove is exposed outside the operation window to realize the communication between the external atmosphere and the air passage; when the inner shell is in the second position, the second air groove is covered by the inner wall of the outer shell, blocking the communication between the operation window and the second air groove.

[0015] In some embodiments, the housing of the main body is cylindrical. One end of the cylinder has an opening to form a receiving cavity inside the cylinder. A power source is disposed inside the other end of the cylinder. Further, a partition is disposed inside the cylinder to separate the power source from the receiving cavity. The power output terminal of the power source forms an electrical contact inside the receiving cavity. Wherein, an atomization core for receiving electric energy to generate aerosol is disposed on the inner housing. After each atomizer moves to the first position, the mouthpiece is exposed outside the receiving cavity, and the atomization core is electrically connected to the electrical contact; after each atomizer moves to the second position, the mouthpiece is received in the receiving cavity, and the atomization core is disconnected from the electrical contact.

[0016] In some embodiments, the electrical contacts in the above embodiments are disposed on a partition or wall shared by a plurality of receiving cavities.

[0017] In some embodiments, each atomizer is provided with a unique identification unit, that is, each inner housing is provided with a unique identification unit, and the identification unit is exposed outside the operation window.

[0032] To make the above objects, features, and advantages of the present application more apparent and understandable, the following will describe in detail the specific implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] In the description of the present application, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] Aerosol delivery devices can be used in different fields, including but not limited to, for example, medical atomization, beauty atomization, and e-cigarettes used in industries such as replacing cigarettes. They are mainly used to atomize an aerosol-forming substrate to form an aerosol. The aerosol-forming substrate can be a liquid substrate such as a medicine solution or a nutrient solution. Taking an e-cigarette that can replace a cigarette as an example, when the e-cigarette is working, the aerosol-forming substrate contains nicotine or synthetic nicotine and can be atomized by an atomizer to form an aerosol. Of course, flavors or sweeteners that stimulate taste or smell can also be added to the aerosol-forming substrate. Existing atomization methods can be heating atomization or non-heating atomization. Among them, heating atomization methods include resistance heating, electromagnetic heating, laser heating, infrared heating, and microwave heating, etc.; non-heating atomization methods include ultrasonic atomization, pressure atomization, mechanical vibration atomization, and compressed air atomization, etc. It can be understood that in the e-cigarette industry, the atomizer includes a mouthpiece. And in some actual products, the cartridge includes a container that forms the outer shape of the cartridge, and an atomization component can be provided in the container. Among them, the atomization component at least includes an atomization chamber and an atomization core (heating element). A liquid storage cavity is formed between the atomization chamber and the inner wall of the container. The atomization chamber is respectively communicated with the mouthpiece and the liquid storage cavity. The atomization core receives the aerosol-forming substrate stored in the liquid storage cavity to atomize and form an aerosol, and the user sucks the aerosol in the atomization chamber through the mouthpiece. Therefore, the cartridge is also called an atomizer in some cases.

[0035] As Figures 1-6 shown, the present application provides a multi-cartridge aerosol delivery device, including a main body and at least two atomizers 20 capable of atomizing an atomization substrate to form an aerosol, and an operation part. Among them, the main body has a housing 10 with a proximal end and a distal end relative to the X-axis along the longitudinal Y-axis. The housing 10 is provided with a receiving cavity 12 near the distal end. One end of the receiving cavity 12 near the distal end is provided with an opening communicated with the receiving cavity 12, and an operation window 11 communicating with the receiving cavity 12 is provided on the housing 10 between the proximal end and the distal end. The operation window 11 defines a first position near the proximal end and a second position near the distal end; each atomizer 20 has an inner housing that defines an air passage allowing aerosol to flow through inside. The inner housing is movably arranged in the receiving cavity 12. There is a gap 50 between the side of the inner housing near the distal end and the housing. The gap 50 is communicated with the air passage; one end of the operation part 30 passes through the operation window 11 and is connected to the inner housing, and the other end of the operation part 30 is exposed outside the operation window 11.

[0036] In some embodiments, as Figure 1 shown, the operation window 11 is strip-shaped. One end of it near the proximal end along the length direction (Y-axis) is the first position, and one end near the distal end (X-axis) is the second position. Further, in some embodiments, the proximal end of the main body is near the bottom of the aerosol delivery device, and the distal end of the main body is near the mouthpiece 21 of the aerosol delivery device.

[0037] When the user uses the operation unit 30 to move the inner shell (atomizer 20) to the first position, the gap 50 is blocked by the outer shell; when the operation unit 30 positions the inner shell at the second position, the gap 50 is at least partially exposed to the operation window 11, such that the airway communicates with the external atmosphere through the gap 50. It can be understood that the inner shell can be configured as a container having the external shape of the atomizer 20, that is, the so-called inner shell here is only the inner shell relative to the main body housing.

[0038] The user pushes out a certain atomizer 20 required according to the desired operation need from the main body accommodation cavity 12, such that the mouthpiece 21 disposed on the atomizer 20 is exposed to the accommodation cavity 12, and the user can suck the aerosol generated by the atomizer 20 by holding the mouthpiece 21 in the mouth. When the user no longer needs to suck the aerosol, the user can operate the exposed atomizer 20 to retract into the accommodation cavity 12, and the mouthpiece 21 retracts into the accommodation cavity 12 along with the atomizer 20, preventing the mouthpiece 21 from being exposed and contaminated, and reducing the overall length of the aerosol delivery device for easy carrying.

[0039] In some embodiments, each atomizer includes a unique mouthpiece with a unique flavor. When the user is not satisfied with the aerosol effect generated by one of the atomizers, the user can operate any atomizer to be exposed to the accommodation cavity 12, such that the corresponding mouthpiece 21 is exposed, preventing the mouthpiece 21 from having a mixed taste due to the alternate use of the atomizer 20 while still sharing the mouthpiece 21.

[0040] In some embodiments, a first air groove communicating with the operation window 11 is provided on one side of the inner wall of the outer shell 10 near the second position. The first air groove extends from the inner wall of the outer shell 10 along the moving direction of the inner shell (atomizer 20) to the operation window 11. It can be understood that one end of the first air groove communicates with the operation window 11, and the other end thereof is a closed end; when the inner shell is at the first position, the first air groove is blocked by the inner shell (atomizer 20); when the inner shell (atomizer 20) is at the second position, the first air groove communicates with the airway. Those skilled in the art can understand that the first air groove is the gap 50 between the outer shell 10 and the inner shell (atomizer 20) that can be blocked or conducted to the airway.

[0041] Similarly, in some embodiments, such as Figure 5As shown, a second air groove is provided on the outer wall of the inner shell on the side close to the proximal end. The second air groove extends from the outer wall of the inner shell along the moving direction of the inner shell until it communicates with the air passage. After the inner shell is in the first position, the second air groove is covered by the inner wall of the outer shell, blocking the communication between the operation window and the second air groove; after the inner shell is in the second position, at least a part of the second air groove is exposed outside the operation window 11 to realize the communication between the external atmosphere and the air passage. Those skilled in the art can understand that the second air groove is a gap between the outer shell 10 and the inner shell (atomizer 20) that can be blocked or conducted to the air passage.

[0042] Specifically, as Figure 2 shown, the inner shell is provided with an atomization core that receives electric energy to generate aerosol. The atomization core is arranged in the air passage. After the inner shell moves to the first position, the mouthpiece 21 is exposed outside the receiving cavity 12. The gap 50 between the inner shell and the outer shell 10 communicates with the air passage. At the same time, the atomization core is electrically connected to the electrical contact. As Figures 4-7 shown, when the inner shell moves to the second position, the mouthpiece 21 is received in the receiving cavity 12. The gap 50 between the inner shell and the outer shell 10 is blocked by the outer shell 10. At the same time, the atomization core is disconnected from the electrical contact, and the atomizer 20 cannot perform normal atomization work.

[0043] In some embodiments, as Figure 3 shown, the outer shell 10 of the above-mentioned main body is cylindrical. One end of the cylinder has an opening to form a receiving cavity 12 inside the cylinder, and a power source 40 is arranged inside the other end of the cylinder. Further, as Figure 4 shown, a partition 13 is arranged inside the cylinder to separate the power source 40 from the receiving cavity 12. The output end extended from the power source 40 forms an electrical contact on the inner wall of the receiving cavity 12. It can be understood that the electrode of the atomization core in the atomizer 20 for receiving electric energy forms a contact point on the side close to the electrical contact. When the atomizer 20 moves to the first position, the contact point contacts the electrical contact to complete the electrical connection.

[0044] Among them, the power source 40 is a rechargeable or non-rechargeable battery.

[0045] In some embodiments, as Figures 2-5As shown, a long operation window 11 communicating with the accommodation cavity 12 is formed on the side wall of the cylindrical outer shell 10 along the Y-axis direction or the longitudinal direction with height of the outer shell 10. One end of the operation window 11 close to the opening in the Y-axis direction is used to define the first position, and one end of the operation window 11 close to the X-axis defines the second position. The atomizer 20 is accommodated in the accommodation cavity 12 through the opening, and the user can operate the atomizer 20 to move within the accommodation cavity 12 between the first position and the second position through the operation window. It can be understood that after the atomizer 20 moves to the first position, the atomizer 20 is electrically connected to the electrical contact and can obtain power supply from the power source 40 to atomize the aerosol-forming matrix to form an aerosol.

[0046] In some embodiments, the above-mentioned accommodation cavity 12 can be a complete cavity or can be divided into two independent accommodation cavities 12. Further, as Figure 4 shown, the accommodation cavity 12 is divided by the partition 13 into accommodation cavities 12 that are equal in number and adapted to the atomizers 20, and each atomizer 20 can move within the corresponding accommodation cavity 12 between the first position and the second position.

[0047] In some embodiments, the electrical contacts in the above embodiments are arranged on the partition 13 or the wall shared by the plurality of accommodation cavities 12. Further, electrical contacts are respectively arranged on both sides of the partition 13 to achieve electrical parallel connection with the corresponding atomizers 20, and the positions of the electrical contacts are close to the second position. It can be understood that the positions of the electrical contacts are close to the open end of the accommodation cavity 12 so that after the atomizer 20 moves towards the open direction to the second position, the atomizer 20 can contact and be electrically connected to the electrical contacts.

[0048] In some embodiments, the multi-cartridge aerosol delivery device further includes an operation part 30 that can move relative to the main body. One end of the operation part 30 passes through the operation window 11 and is arranged in the accommodation cavity 12 and is connected to the atomizer 20. As Figure 4 shown, one end of the operation part 30 passes through the operation window 11 to form a support 31 in the accommodation cavity 12, and the atomizer 20 is fixed on the support 31. When the user operates the operation part 30 to move within the operation window 11, the atomizer 20 makes the same moving action within the accommodation cavity 12. Further, the other end of the operation part 30 is exposed outside the operation window 11 to form an operation end 32 for the user to operate the atomizer 20 to move relative to the main body between the first position and the second position. Further, the operation part 30 can operate at least one atomizer 20 or a plurality of atomizers 20 among the plurality of atomizers 20 to move relative to the main body between the first position and the second position simultaneously.

[0049] In some embodiments, the multi-cartridge aerosol delivery device is provided with the operation parts 30 corresponding to the number of the atomizers 20, and each operation part 30 is connected to a corresponding atomizer 20 to operate the corresponding atomizer 20 to move between a first position and a second position. Further, the operation part 30 is at least partially disposed in the accommodation cavity 12 to carry the atomizer 20.

[0050] In some embodiments, a part of the operation part 30 is exposed outside the housing 10, and the surface of the part of the operation part 30 exposed outside the housing 10 protrudes or is flush with the surface of the housing 10. It can be understood that the part of the operation end 32 of the operation part 30 protruding from the housing 10 can be toggled by the user. If the part of the operation end 32 of the operation part 30 exposed outside the housing 10 is flush with the surface of the housing 10, the user can operate the operation part 30 by pushing.

[0051] As Figure 7 shown, the aerosol delivery device provided by the present application has a first atomizer 20A and a second atomizer 20B. Among them, one end of the housing 10 of the aerosol delivery device has an accommodation cavity 12 for accommodating 2 atomizers. The housing 10 is provided with a first operation window 11A and a second operation window 11B equal in number to the atomizers 20. Each operation window communicates with the accommodation cavity 12. The first operation part 30A and the second operation part 30B equal in number to the atomizers 20 are at least partially exposed outside the operation window 11. Refer to Figure 6 shown, the first atomizer 20A is moved by the user using the first operation part 30A to the second position limited by the range of the operation window 11. The first nozzle 21A on the first atomizer 20A is exposed outside the accommodation cavity 12. The gap 50 between the housing 10 and the inner housing communicates with the air passage. At the same time, the first atomizer 20A is electrically connected to the electrical contact on the inner wall of the accommodation cavity 12; while the second atomizer 20B is not moved and operated. It is located in the first position and is accommodated in the accommodation cavity 12. At the same time, the second nozzle 21B of the second atomizer 20B is also hidden in the accommodation cavity 12. The gap 50 between the housing 10 and the inner housing is blocked and cannot communicate with the air passage. At the same time, the second atomizer 20B cannot form an electrical connection with the electrical contact either.

[0052] In some embodiments, each atomizer is provided with a unique identification unit that allows the user to identify the flavor or other different functions of the atomizer. Specifically, the identification unit may be at least one of a pattern and a color. In some embodiments, the identification unit can be configured on the nozzle to configure the nozzle into different shapes for the user to identify.

[0053] Compared with the prior art, multiple atomizers each including a mouthpiece can move relative to the main body separately, so that when the mouthpiece is exposed outside the main body, it can be ventilated, powered on and used by the user; when the mouthpiece is hidden inside the main body, it cannot be ventilated or powered on, so as to prevent the user from still using the same mouthpiece after switching the atomizer.

[0054] The above are only partial or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the overall concept of the present invention, or any direct / indirect application in other related technical fields is included in the scope of protection of the present invention.
