[0009] The aerosol generating device has a plurality of air outlet channels, and the aerosol generated by the corresponding aerosol generating substrate in one of the oil reservoirs is communicated with one of the mouthpieces through one of the air outlet channels.

[0010] The mouthpieces have a storage state and a working state. In the working state, one end of the mouthpiece away from the air outlet channel is exposed to the housing assembly. In the storage state, the mouthpiece is stored inside the housing assembly. When one of the mouthpieces is in the working state, the remaining mouthpieces are in the storage state.

[0011] In some embodiments, the housing assembly comprises a housing body and a housing cover arranged on the housing body, and the housing body and the housing cover define the containing area;

[0012] In the height direction of the aerosol generating device, a part of the area on the top side of the containing area is open and forms a first opening, and the housing cover comprises a shielding part which constitutes the top wall of the containing area and shields the mouthpiece in the storage state.

[0013] In some embodiments, the shell cover is rotatably arranged on the shell body, and the shell cover is rotated relative to the shell body to switch the suction nozzle shielded by the shielding portion; and / or,

[0014] The suction nozzle comprises a connecting section, a pleated section and a suction section, one end of the connecting section is communicated with the air outlet channel, the pleated section is arranged at the other end of the connecting section, and the suction section is arranged at one end of the pleated section away from the connecting section.

[0015] In some embodiments, in the height direction of the aerosol generating device, the minimum size of the end of the shell cover exposed outside the shell body in connection with the shell body is not less than 5 mm; and / or,

[0016] The shell cover is provided with a first rotation matching portion, the shell body is provided with a second rotation matching portion, one of the first rotation matching portion and the second rotation matching portion is a guide groove, and the other is a guide protrusion, and at least part of the guide protrusion is arranged in the guide groove.

[0017] In some embodiments, the suction nozzle in the working state is a first suction nozzle, the first suction nozzle corresponds to a first oil tank, part of the structure of the first oil tank is exposed to the aerosol generating device through the first opening, and in the plane perpendicular to the height direction of the aerosol generating device, the first oil tank and the shielding portion are arranged in a spaced manner.

[0018] In some embodiments, in the plane perpendicular to the height direction of the aerosol generating device, the spacing between the first oil tank and the shielding portion is 1 mm to 2 mm.

[0019] In some embodiments, part of the area on the side of the accommodating area is open and forms a second opening, the suction nozzle in the working state is a first suction nozzle, the first suction nozzle corresponds to a first oil tank, and at least part of the first oil tank is exposed to the aerosol generating device through the second opening.

When a user inhales different flavored aerosols, they can inhale through the nozzle on the oil tank corresponding to the flavor. The connection between the nozzle and the corresponding air outlet channel does not need to be disconnected. After inhalation, the condensate in the nozzle can flow back to the atomizing core of the aerosol generating device through the corresponding air outlet channel, thus being reusable. This helps reduce condensate residue and the likelihood of dirt accumulation leading to poor hygiene. At the same time, different flavored aerosols reach the mouth through independent channels via specific nozzles, avoiding the situation where multiple oil tanks share one nozzle. This helps improve the problem of flavor mixing when switching flavors. Attached Figure Description

[0040] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The present application provides an aerosol generating device.

[0042] It should be noted that the specific type of the aerosol generating device of the embodiments of the present application is not limited. Exemplarily, the aerosol generating device can be a medical atomization equipment, can be an air humidifier, or can be an electronic cigarette or the like atomization equipment.

[0043] Please refer to Figure 1 and Figure 2 , the aerosol generating device comprises a shell assembly 10, an oil tank 20 and a suction nozzle 30.

[0044] The shell assembly 10 is provided with a containing area 10a; the number of the oil tanks 20 is multiple, and each oil tank 20 is arranged in the containing area 10a.

[0045] It should be noted that the number of the containing areas 10a is not limited.

[0046] For example, the number of the containing areas 10a can be one-to-one corresponding to the number of the oil tanks 20. In this way, one oil tank 20 is arranged in each containing area 10a, and during the dismounting process of the oil tank 20 from the containing area 10a, no friction, interference and the like problems will be caused with other oil tanks 20, so that the dismounting of each oil tank 20 is facilitated.

[0047] For example, the number of accommodation areas 10a can be less than the number of oil reservoirs 20, i.e., two or more oil reservoirs 20 can be arranged in one accommodation area 10a. Further, the number of accommodation areas 10a can be one, so that all the oil reservoirs 20 are arranged in one accommodation area 10a. It can be understood that the reduction in the number of accommodation areas 10a is conducive to simplifying the structure of the shell assembly 10 and reducing the production difficulty of the shell assembly 10, thereby improving the production efficiency of the shell assembly 10.

[0048] When the plurality of oil reservoirs 20 are arranged in the same accommodation area 10a, the fixing manner of each oil reservoir 20 in the accommodation area 10a is not limited.

[0049] For example, in the circumferential direction of the aerosol generating device, the two adjacent oil reservoirs 20 are magnetically attracted and matched. In this way, the fixing manner of each oil reservoir 20 in the accommodation area 10a is relatively simple and convenient for user operation. Moreover, the interaction between the oil reservoirs 20 is conducive to reducing the risk of a single oil reservoir 20 falling out of the accommodation area 10a.

[0050] In the embodiments of the present application, the "circumferential direction of the aerosol generating device" can be understood in the following manner:

[0051] The direction of rotation around the axial direction of the height direction of the aerosol generating device is the circumferential direction. It should be noted that the height direction of the aerosol generating device is understood based on the normal use state, as shown in FIG. 1. Figure 1

[0052] Each oil reservoir 20 can store aerosol generating substrate. In this way, each oil reservoir 20 can store aerosol generating substrate of different flavors, so that one aerosol generating device can provide different smoking flavors.

[0053] The number of nozzles 30 corresponds to the number of oil reservoirs 20, and the aerosol generating device has a plurality of air outlet channels 20a. The aerosol generated by the corresponding aerosol generating substrate in one oil reservoir 20 is communicated with one nozzle 30 through one air outlet channel 20a.

[0054] The aerosol generated by the corresponding aerosol generating substrate in each oil reservoir 20 by heating and atomization can flow out through the air outlet channel 20a corresponding to the oil reservoir 20, and the user can smoke the corresponding flavor of aerosol by sucking through the nozzle 30 corresponding to the oil reservoir 20.

[0055] The nozzle 30 has a storage state and a working state. In the working state, the end of the nozzle 30 away from the air outlet channel 20a is exposed to the shell assembly 10. In the storage state, the nozzle 30 is stored inside the shell assembly 10. When one nozzle 30 is in the working state, the remaining nozzles 30 are in the storage state.​

[0056] Here, the "one end of the suction nozzle 30 is exposed to the outer surface of the shell assembly 10 away from the air outlet passage 20a" means that one end of the suction nozzle 30 is exposed to the outer surface of the shell assembly 10.

[0057] Here, the suction nozzle 30 in the working state is the first suction nozzle 60, and the oil tank 20 corresponding to the first suction nozzle 60 is the first oil tank 40; the remaining suction nozzles 30 in the storage state are the second suction nozzles 70, and the oil tanks 20 corresponding to the second suction nozzles 70 are the second oil tanks 50.

[0058] It can be understood that the first suction nozzle 60 and the first oil tank 40 are each only one, and the second suction nozzle 70 and the second oil tank 50 can be more than one. For example, the aerosol generating device includes two suction nozzles 30 and two oil tanks 20 in total, one of the suction nozzles 30 is the first suction nozzle 60, the other suction nozzle 30 is the second suction nozzle 70, one of the oil tanks 20 is the first oil tank 40, and the other oil tank 20 is the second oil tank 50; for another example, the aerosol generating device includes three suction nozzles 30 and three oil tanks 20, one of the suction nozzles 30 is the first suction nozzle 60, and the other two suction nozzles 30 are the second suction nozzles 70, one of the oil tanks 20 is the first oil tank 40, and the other two oil tanks 20 are the second oil tanks 50.

[0059] In this way, the suction nozzle 30 in the storage state can be hidden inside the shell assembly 10, and thus it is beneficial to reduce the probability of dirt entering the suction nozzle 30 in the storage state; at the same time, only the suction nozzle 30 in the working state is exposed to the outer surface of the shell assembly 10, and thus it is beneficial to reduce the probability of the user sucking the wrong suction nozzle 30, thereby improving the user's experience.

[0060] In the related art, the aerosol generating device is provided with only one suction nozzle, and the position of the suction nozzle is adjusted to make the suction nozzle communicate with the air outlet passages of different oil tanks, so as to suck aerosols of different flavors. The aerosol generating device of this structure is prone to leaving more condensate on the displacement path of the suction nozzle, resulting in poor hygiene and the problem of flavor mixing after switching flavors caused by the remaining condensate.

[0061] The aerosol-generating device of the embodiment of the present application, one oil tank 20 corresponds to one suction nozzle 30, when the user sucks aerosol of different flavors, can suck the suction nozzle 30 on the oil tank 20 of different flavors by mouth, the connection relationship between the suction nozzle 30 and the air outlet channel 20a corresponding to the suction nozzle 30 does not need to be removed, and the condensed liquid in the suction nozzle 30 can flow back to the inside of the atomizing core of the aerosol-generating device through the air outlet channel 20a corresponding to the suction nozzle 30 after the suction is finished, so that it can be repeatedly consumed, thereby, it is helpful to reduce the residue of the condensed liquid and reduce the probability of poor hygiene caused by dirt accumulation; at the same time, the aerosol of different flavors realizes independent channel to the mouth through a specific suction nozzle 30, avoiding the situation that multiple oil tanks 20 share one suction nozzle 30, thereby, it is helpful to improve the suction string taste problem after switching flavors.

[0062] In some embodiments, referring to Figure 3 and Figure 5 , each oil tank 20 is provided with an air outlet channel 20a, that is, each oil tank 20 is provided with an air outlet channel 20a, and each suction nozzle 30 is arranged on each oil tank 20, and one end of the suction nozzle 30 is in communication with the air outlet channel 20a of the oil tank 20 corresponding to the suction nozzle 30.

[0063] In this way, the aerosol generated by the aerosol-generating substrate stored in the oil tank 20 directly flows out of the oil tank 20, and the aerosol does not flow through other components of the aerosol-generating device except the oil tank 20 and the suction nozzle 30 corresponding to the oil tank 20. After the aerosol-generating substrate in the oil tank 20 is used up, the oil tank 20 can be replaced integrally with the suction nozzle 30 corresponding to the oil tank 20, so that after replacing the new oil tank 20, there will be no taste mixing problem between the aerosol-generating substrate stored in the oil tank 20 before replacement and the aerosol-generating substrate stored in the oil tank 20 after replacement, thereby helping to improve the user's suction experience.

[0064] In some embodiments, referring to Figures 1 to 3 , Figure 5 , the oil tank 20 is provided with a receiving groove 20b, one end of the air outlet channel 20a is in communication with the receiving groove 20b, and in the storage state, the remaining part of the suction nozzle 30 except that arranged in the air outlet channel 20a is located in the receiving groove 20b.

[0065] In this way, the suction nozzle 30 in the storage state can accommodate part of the volume of the suction nozzle 30, thereby helping to reduce the volume of the suction nozzle 30 in the storage state protruding from the outer surface of the oil tank 20, thereby facilitating the storage of the suction nozzle 30 in the storage state inside the shell assembly 10.

[0066] The material of the suction nozzle 30 is not limited herein. For example, the suction nozzle 30 can be made of rubber, silica gel or the like. That is, the suction nozzle 30 is a flexible tube. When the suction nozzle 30 is in the working state, the end of the suction nozzle 30 away from the air outlet channel 20a protrudes from the outer surface of the oil tank 20, so as to facilitate the user to hold the suction nozzle 30 in the mouth for suction. When the suction nozzle 30 is switched to the storage state, the flexible tube is deformed, so that the suction nozzle 30 is stored in the storage groove 20b except for the part arranged in the air outlet channel 20a.

[0067] The flexible tube can be an elastic flexible tube. That is, under the constraint of external force or other structures, the suction nozzle 30 is in the storage state, and the part of the suction nozzle 30 except for the part arranged in the air outlet channel 20a is stored in the storage groove 20b. After the constraint of external force or other structures is removed, the suction nozzle 30 restores the elastic deformation and is automatically switched to the working state. Thus, the user needs to perform less operation, and the use of the aerosol generating device is more convenient.

[0068] The flexible tube can also be a plastic flexible tube. Herein, the suction nozzle 30 needs to be deformed by external force when it is switched between the working state and the storage state. Therefore, the suction nozzle 30 can remain in the storage state when it is not constrained by other structures or external force. Thus, it is beneficial to simplify the structure of the aerosol generating device and reduce the production cost of the aerosol generating device.

[0069] It should be noted that the direction of the deformation of the suction nozzle 30 is not limited.

[0070] Exemplarily, the suction nozzle 30 can be arranged to be retractable along the axial direction thereof. In the working state, one end of the suction nozzle 30 in the axial direction protrudes out of the storage groove 20b. When the suction nozzle 30 is switched from the working state to the storage state, the suction nozzle 30 is deformed along the axial direction thereof and the axial dimension thereof is shortened, so that the end of the suction nozzle 30 away from the air outlet channel 20a can be retracted into the storage groove 20b.

[0071] Exemplarily, as shown in Figure 2 , Figure 4 and Figure 5 , the suction nozzle 30 can also be a bending deformation structure. Specifically, in the process of switching the suction nozzle 30 from the working state to the storage state, a part of the suction nozzle 30 is bent and deformed, so that the end of the suction nozzle 30 away from the air outlet channel 20a can fall down and be stored in the storage groove 20b.

[0072] In some embodiments, as shown in Figures 1 to 3 , the shell assembly 10 includes a shell body 11 and a shell cover 12 arranged on the shell body 11, and the shell body 11 and the shell cover define a containing area 10a. In the height direction of the aerosol generating device, a part of the top side of the containing area 10a is open and forms a first opening 12a. The shell cover 12 includes a shielding part 121, which constitutes a top wall of the containing area 10a and shields the suction nozzle 30 in the storage state.

[0073] It should be noted that the height direction of the aerosol-generating device needs to be understood based on its normal use state. Exemplarily, the height direction of the aerosol-generating device is as shown in Figure 1 .

[0074] It should be noted that in the embodiments of the present application, "upper", "lower", "top", "bottom" all need to be understood based on the height direction of the aerosol-generating device, and specifically as shown in Figure 1 .

[0075] Specifically, the first opening 12a is provided on the shell cover 12, and the accommodation area 10a is in communication with the outside of the aerosol-generating device through the first opening 12a, and the side wall of the shielding part 121 can constitute part of the outer edge of the first opening 12a.

[0076] Each oil tank 20 is exposed on the top side of the accommodation area 10a. In this way, when the air outlet channel 20a corresponding to the oil tank 20 is arranged at the oil tank 20, the mouthpiece 30 corresponding to the oil tank 20 is facilitated to be installed in the air outlet channel 20a corresponding to the oil tank 20.

[0077] Here, the mouthpiece 30 in the storage state is shielded by the shielding part 121, so as to facilitate reducing the probability of impurities such as dust entering the inside of the mouthpiece 30; at the same time, the user cannot hold the mouthpiece 30 in the storage state in the mouth to suck, reducing the probability of the user sucking the wrong mouthpiece 30, thereby facilitating improving the user's experience.

[0078] In some embodiments, referring to Figures 1 to 4 , the mouthpiece 30 in the working state is a first mouthpiece 60, the oil tank 20 corresponding to the first mouthpiece 60 is a first oil tank 40, part of the structure of the first oil tank 40 is exposed to the aerosol-generating device through the first opening 12a, and in a plane perpendicular to the height direction of the aerosol-generating device, the first oil tank 40 and the shielding part 121 are arranged in a spaced manner.

[0079] It should be noted that in the embodiments of the present application, the first mouthpiece 60 does not specifically refer to a specific mouthpiece 30, and the first oil tank 40 also does not specifically refer to a specific oil tank 20. All mouthpieces 30 of the aerosol-generating device can be switched to the working state, and the mouthpiece 30 switched to the working state is the first mouthpiece 60 of the embodiments of the present application, and at this time, the oil tank 20 corresponding to the mouthpiece 30 is the first oil tank 40.

[0080] In the embodiments, each oil tank 20 can be disassembled from the first opening 12a along the height direction of the aerosol-generating device, and during the disassembly process, the shielding part 121 does not interfere with the disassembly of the oil tank 20, thereby facilitating the disassembly of each oil tank 20, thereby facilitating improving the disassembly efficiency of each oil tank 20.

[0081] In addition, when users use the aerosol generating device and need to replace the oil tank 20 themselves, the oil tank 20 is easier to disassemble and assemble, which helps to improve the user experience.

[0082] In some embodiments, please refer to Figure 3 and Figure 4 On a plane perpendicular to the height direction of the aerosol generating device, the distance between the first oil tank 40 and the shielding part 121 is 1mm to 2mm. For example, it can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc.

[0083] For example, the distance between the first oil tank 40 and the shielding part 121 is as follows: Figure 4 As shown in D1.

[0084] In this embodiment, the distance between the first oil tank 40 and the shielding part 121 is relatively reasonable. On the one hand, the gap between the first oil tank 40 and the shielding part 121 is not less than 1mm, which helps to ensure the convenience of disassembling and assembling each oil tank 20. On the other hand, the gap between the first oil tank 40 and the shielding part 121 is not greater than 2mm, which helps to ensure the shielding effect of the shielding part 121 on other oil tanks 20 and the suction nozzles 30 on other oil tanks 20.

[0085] In some embodiments, please refer to Figures 1 to 3 The cover 12 is rotatably disposed on the shell body 11. The cover 12 rotates relative to the shell body 11 to switch the nozzle 30 blocked by the blocking part 121.

[0086] In this embodiment, it can be that during the rotation of the cover 12 relative to the body 11, the blocking part 121 acts on the nozzle 30 in the working state and switches the nozzle 30 to the storage state; or it can be that the nozzle 30 in the working state is switched to the storage state manually or by other means, and then the cover 12 is rotated so that the blocking part 121 blocks the nozzle 30 that has been switched to the storage state.

[0087] In this embodiment, when switching the flavor of the inhalation, the mouthpiece 30, which is currently in working state, will switch to the storage state. At this time, the user can operate the cover 12 to cover the mouthpiece 30 after it has switched to the storage state, which makes it convenient for the user to operate.

[0088] In some embodiments, please refer to Figures 1 to 3 , Figure 5 The cover 12 rotates relative to the body 11 and can switch the working nozzle 30 to the storage state through the blocking part 121.

[0089] The shell cover 12 rotates under the action of an external force, and contacts the side wall of the suction nozzle 30 in the working state through the shielding part 121. The shielding part 121 extrudes the suction nozzle 30 in the working state under the action of the torsion force, so that the suction nozzle 30 is deformed and switched to the storage state.

[0090] In this embodiment, the shielding part 121 can synchronously drive the suction nozzle 30 in the working state to switch to the storage state during the switching of the shielding suction nozzle 30. That is, the user does not need to separately switch the suction nozzle 30 in the working state to the storage state. In this way, the user's operation during the switching of the suction taste is less, and the use is more convenient.

[0091] In some embodiments, referring to Figure 3 , Figure 5 and Figure 7 , the suction nozzle 30 includes a connecting section 31, a pleated section 32, and a suction section 33. One end of the connecting section 31 is arranged in the air outlet channel 20a, the pleated section 32 is arranged at the other end of the connecting section 31, and the suction section 33 is arranged at one end of the pleated section 32 away from the connecting section 31.

[0092] It should be noted that the length of the pleated section 32 is not limited, and the specific size can be designed according to actual needs.

[0093] One end of the connecting section 31 can be assembled in the air outlet channel 20a in an interference fit. In this way, the user can replace the new suction nozzle 30 after using the suction nozzle 30 for a period of time.

[0094] In this embodiment, by arranging the pleated section 32 on the suction nozzle 30, the bending deformation of the suction nozzle 30 is facilitated, so that the suction nozzle 30 can be switched between the working state and the storage state.

[0095] Further, based on the embodiment that the suction nozzle 30 is a plastic hose, by arranging the pleated section 32 on the plastic hose, the plastic hose can be kept in the working state or the storage state.

[0096] In some embodiments, referring to Figure 3 and Figure 5 , in the height direction of the aerosol generating device, the minimum size of the end of the shell cover 12 exposed to the shell body 11 is not less than 5 mm. For example, it can be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0097] Exemplarily, the minimum size of the end of the shell cover 12 exposed to the shell body 11 is shown as D2 in Figure 5 .

[0098] By designing the size to be no less than 5 mm, when the user holds the aerosol generating device, it is convenient to apply a torsional force to the shell cover 12, thereby facilitating the user to reduce the difficulty of twisting the shell cover 12 and improving the user's experience.

[0099] It can be understood that the maximum value of the size can be controlled according to the overall height size of the aerosol generating device, so that the user can apply a torsional force.

[0100] In some embodiments, referring to Figure 3 , Figure 5 and Figure 6 , the shell cover 12 is provided with a first rotation cooperation part 122, and the shell body 11 is provided with a second rotation cooperation part 11a. One of the first rotation cooperation part 122 and the second rotation cooperation part 11a is a guide groove, and the other is a guide protrusion. At least part of the guide protrusion is arranged in the guide groove.

[0101] The guide groove can provide a displacement path for the guide protrusion, so as to facilitate the shell cover 12 to rotate according to the designed trajectory under the torsional force. In this way, it is beneficial to improve the reliability and stability of the rotation cooperation between the shell cover 12 and the shell body 11.

[0102] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5 , part of the area around the accommodation area 10a is open and forms a second opening 12b. The mouthpiece 30 in the working state is a first mouthpiece 60. The first mouthpiece 60 corresponds to a first oil tank 40. At least part of the first oil tank 40 is exposed to the aerosol generating device through the second opening 12b.

[0103] Here, the side of the accommodation area 10a refers to the side corresponding to the direction perpendicular to the height direction of the aerosol generating device.

[0104] In this way, after each oil tank 20 is switched to the working state, the liquid storage tank of the oil tank 20 can also be exposed to the aerosol generating device through the second opening 12b, so as to facilitate the user to confirm the liquid level of the aerosol generating substrate in the first oil tank 40, thereby facilitating the user to confirm whether a new oil tank 20 needs to be replaced.

[0105] In some embodiments, referring to Figure 1 , Figure 4 and Figure 5 , neither the first opening 12a nor the second opening 12b is a full-enclosing structure. The inner wall surface of the first opening 12a is a first structure surface 123, and the inner wall surface of the second opening 12b is a second structure surface 124. The two ends of the first structure surface 124 are respectively connected to the two ends of the second structure surface 124.

[0106] It can be understood that the side wall surface of the shielding portion 121 constitutes at least part of the first structure surface 123.

[0107] That is, the first opening 12a is a semi-enclosed structure (the first structure surface 123 is a bent section); or, the first structure surface 123 extends in a straight line. The second opening 12b is also a semi-enclosed structure.

[0108] In this embodiment, there is no spacing wall between the first opening 12a and the second opening 12b, that is, the first opening 12a and the second opening 12b constitute an integral gap, so that the oil tank 20 is more convenient to disassemble and assemble.
