The volume of the liquid storage chamber of the atomizer (i.e., the liquid storage capacity of the atomizer) is generally fixed, so that the number of puffs that the atomizer can provide for the user is limited. Once the atomized liquid in the liquid storage chamber of the atomizer is consumed, it is usually necessary to replace the atomizer with a new one before continuing to use it, which increases the user's usage cost.

[0061] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0062] Please refer to Figure 3-4 , Figure 8-9 , Figure 13-14 and Fig.17 The embodiment of the utility model provides an atomizer 2, which is used to be detachably assembled into one with an expansion bin 1 having a first suction nozzle 115 and a liquid outlet pipe 12 for use, such as Figure 1-2 , Figure 6-7 , Figure 10-12 , Figure 15-16 as well as Figure 18-19 As shown, the expansion chamber 1 is provided with a first airway 114 connected to the first suction nozzle 115 and a first liquid storage chamber 10 connected to the liquid outlet pipe 12. Specifically, the atomizer 2 provided in the embodiment of the utility model includes a second shell 21, a second suction nozzle 23 and an atomizing core 22 installed in the second shell 21, the second shell 21 is provided with a second liquid storage chamber 211 and a second airway 212 separated from each other, the second shell 21 is provided with at least one injection hole 213 connected to the second liquid storage chamber 211, the second suction nozzle 23 is detachably connected to the second shell 21 and covers each injection hole 213, and the second suction nozzle 23 is connected to the second airway 212, and the atomizing core 22 is respectively connected to the second liquid storage chamber 211 and the second airway 212;

[0063] Among them, when the second suction nozzle 23 is removed from the second shell body 21 and the expansion chamber 1 and the atomizer 2 are assembled into one, the first air channel 114 is connected with the second air channel 212, and the liquid outlet pipe 12 is inserted into the injection hole 213 and connected with the second liquid storage chamber 211, so that the atomized liquid in the first liquid storage chamber 10 can be injected into the second liquid storage chamber 211 through each liquid outlet pipe 12.

[0064] In this embodiment, it should be noted that, in a specific implementation, the number of the injection holes 213 can be flexibly set according to actual needs, and can be one, two, or more than two. This embodiment does not impose a specific limitation on this. For example, Figure 3 , Figure 13-14 as well as Fig.17 As shown, the number of the injection holes 213 can be set to two.

[0065] Based on the above structural design, the use principle of the atomizer 2 provided in this embodiment is as follows:

[0066] Please refer to Figure 3-7 As shown, before the expansion chamber 1 and the atomizer 2 are assembled into one body for use, the expansion chamber 1 can be inverted so that the liquid outlet port of the liquid outlet pipe 12 of the expansion chamber 1 is arranged upward (such as Figure 5 As shown); then, the pre-prepared atomized liquid is injected into the first liquid storage chamber 10 of the expansion chamber 1 at the liquid outlet pipe 12; then, the second suction nozzle 23 of the atomizer 2 is removed from the second shell 21 of the atomizer 2, and then the expansion chamber 1 pre-filled with the atomized liquid is assembled with the atomizer 2 at the injection hole 213 of the atomizer 2, so that the first liquid storage chamber 10 of the expansion chamber 1 can be connected with the second liquid storage chamber 211 of the atomizer 2 through the liquid outlet pipe 12, and the first airway 114 of the expansion chamber 1 is connected with the second airway 212 of the expansion chamber 1. In this way, during the atomization work of the atomizer core 22, as the atomizer 2 The atomized liquid in the second liquid storage chamber 211 is gradually consumed by the atomizer core 22, and the atomized liquid in the first liquid storage chamber 10 of the expansion chamber 1 can be injected into the second liquid storage chamber 211 of the atomizer 2 through each liquid outlet pipe 12 for replenishment. At the same time, when the user inhales at the first suction nozzle 115, an inhalation airflow is formed on the path where the second airway 212, the first airway 114, and the first suction nozzle 115 are sequentially connected. When the inhalation airflow flows through the atomizer core 22, the inhalation airflow takes away the aerosol generated by the atomizer core 22, and the aerosol finally flows out from the first suction nozzle 115 to the user's mouth along with the inhalation airflow and is inhaled by the user.

[0067] In the technical solution of the present embodiment, on the first hand, since the atomizer 2 provided in the present embodiment can be assembled into one with the expansion bin having the first liquid storage chamber 10 for use, it is possible to expand the liquid storage capacity of the atomizer 2 without changing the volume of the second liquid storage chamber 211 of the atomizer 2, thereby enabling the atomizer 2 to provide the user with more inhalation puffs and enabling the atomizer 2 to be reused without replacement, thereby reducing the user's use cost.

[0068] Secondly, since the second shell 21 of the atomizer 2 provided in this embodiment is provided with an injection hole 213, when the atomized liquid in the second liquid storage chamber 211 of the atomizer 2 is consumed, the user can remove the second suction nozzle 23 of the atomizer 2 and inject the pre-prepared atomized liquid into the second liquid storage chamber 211 of the atomizer 2 through the injection hole 213 for replenishment. After the atomized liquid is replenished, the second suction nozzle 23 can be put back into place so that the atomizer 2 can continue to be used without replacing a new atomizer 2, thereby reducing the user's usage cost.

[0069] Thirdly, since the atomizer 2 provided in this embodiment has the second suction nozzle 23, the user can use the atomizer 2 alone for suction. Moreover, since the atomizer 2 can also be assembled into a whole with the expansion bin 1 having the first suction nozzle 115 for suction, the user can flexibly choose the usage method of the atomizer 2 according to actual usage requirements, thereby improving the flexibility of the use of the atomizer 2.

[0070] For further information, please refer to Figure 3-4 , Figure 7 as well as Fig.10 In some optional embodiments of the utility model, each injection hole 213 is located at the top surface of the second shell 21, and each injection hole 213 is sealed and connected with a seal 24, wherein, in the specific implementation, the specific structural form of the seal 24 can be a sealing film (aluminum foil, silicone film, rubber film, etc.), or a sealing plug (such as a rubber plug or a silicone plug), or a sealing cover, and this embodiment does not impose specific restrictions on this. It should be noted here that when the structural form of the seal 24 is a sealing film, when the second suction nozzle 23 is detached from the second shell 21 and the expansion bin 1 is assembled into one with the atomizer 2, the liquid outlet pipe 12 will pierce the corresponding sealing film and pass through the injection hole 213 and then communicate with the second liquid storage chamber 211. At this time, the technical solution of this embodiment can be applied to the disposable scenario of assembling the atomizer 2 and the expansion bin 1 into one for suction (in this scenario, when the atomized liquid in the atomizer 2 and the expansion bin 1 is consumed, the user can discard the atomizer 2 and the expansion bin 1 as a whole). When the sealing member 24 is in the form of a sealing plug or a sealing cover, before the expansion chamber 1 and the atomizer 2 are assembled into one, the second suction nozzle 23 needs to be detached from the second shell 21 and the sealing plug or the sealing cover needs to be removed from the liquid injection hole 213, and then the expansion chamber 1 and the atomizer 2 are assembled into one, so that the corresponding liquid outlet pipe 12 is inserted into the corresponding liquid injection hole 213 and connected to the second liquid storage chamber 211. At this time, the technical solution of this embodiment can be applied to the one-time use scenario of assembling the atomizer 2 and the expansion chamber 1 into one for suction, and can also be applied to the scenario of repeated recycling of the atomizer 2 for suction (in this scenario, when the atomized liquid in the atomizer 2 is consumed, the user can remove the second suction nozzle 23 and the sealing member 24 in turn, and then inject the pre-prepared atomized liquid into the second liquid storage chamber 211 of the atomizer 2 through the liquid injection hole 213 for replenishment, thereby realizing the recycling and reuse of the atomizer 2).

[0071] In the present embodiment, based on the above structural design, by providing a sealing member 24 for sealing the liquid injection hole 213 at the liquid injection hole 213 of the atomizer 2, on the first hand, it is possible to better prevent the atomized liquid in the second liquid storage chamber 211 of the atomizer 2 from leaking to the outside through the installation gap between the second shell 21 and the second suction nozzle 23 from the liquid injection hole 213 during the process of the user using the atomizer 2 alone for suction; on the second hand, it is possible to reduce the risk of the atomized liquid in the second liquid storage chamber 211 leaking from the connection between the atomizer core 22 and the second liquid storage chamber 211 before the atomizer 2 of the present embodiment is used for suction, because if the second storage chamber 211 of the atomizer 2 is connected to the atomizer core 22, the atomizer core 22 will be connected to the second liquid storage chamber 211. The liquid chamber 211 is connected to the outside through the injection hole 213, which will cause the internal air pressure of the second liquid storage chamber 211 to be the same as the external air pressure. Under the dual effects of the internal air pressure of the second liquid storage chamber 211 and the gravity of the atomized liquid itself, the atomized liquid in the second liquid storage chamber 211 will more easily leak from the connection between the atomizer core 22 and the second liquid storage chamber 211. On the third aspect, when the structural form of the sealing member 24 is a sealing film, it can also effectively reduce the risk of leakage of the atomized liquid in the second liquid storage chamber 211 from the injection hole 213 due to tipping over the atomizer 2 during the process of assembling the expansion chamber 1 pre-filled with atomized liquid and the atomizer 2 pre-filled with atomized liquid into one.

[0072] In some other optional embodiments of the present invention, please refer to Fig.17 , a sealing structure 26 is provided in the bottom of the second suction nozzle 23 (specifically, the part of the second suction nozzle 23 that contacts the top of the second shell 21), and the sealing structure 26 covers each injection hole 213. Such a configuration can also better prevent the atomized liquid in the second liquid storage chamber 211 of the atomizer 2 from leaking to the outside through the installation gap between the second shell 21 and the second suction nozzle 23 from the injection hole 213 when the user uses the atomizer 2 alone for suction. Among them, in the specific implementation, the material of the sealing structure 26 can be a sealing material of the type of rubber, silica gel, silicone rubber, etc. It should be noted here that the technical solution of this embodiment can be applicable to the one-time use scenario of assembling the atomizer 2 and the expansion chamber 1 into one body for suction, and can also be applicable to the scenario of repeatedly using the atomizer 2 for suction.

[0073] For further information, please refer to Figure 3-5 , Figure 7 , Figure 13-15 as well as Figure 17-19In some optional embodiments of the utility model, at least one buckle portion 214 is convexly provided on the top side wall of the second shell 21, and the buckle portion 214 is used to buckle with the second suction nozzle 23 or the expansion chamber 1. It can be understood here that in some application scenarios where the atomizer 2 is used alone, the bottom inner wall of the second suction nozzle 23 is provided with a groove adapted to the buckle portion 214 of the second shell 21. Before the second suction nozzle 23 is detached from the top of the second shell 21, the buckle portion 214 of the second shell 21 will be buckled in the groove of the second suction nozzle 23, thereby realizing a detachable connection between the second shell 21 and the second suction nozzle 23. In some application scenarios where the atomizer 2 and the expansion chamber 1 are assembled into one for use, a card slot 1160 compatible with the buckle portion 214 is provided on the inner wall of the connecting portion 116 located at the bottom of the expansion chamber 1. When the second suction nozzle 23 is detached from the second shell 21 and the expansion chamber 1 is assembled into one with the second shell 21 of the atomizer 2, the buckle portion 214 of the second shell 21 will be buckled into the card slot 1160 of the expansion chamber 1, thereby realizing a detachable connection between the expansion chamber 1 and the second shell 21 of the atomizer 2.

[0074] For further information, please refer to Figure 17-18 In some optional embodiments of the utility model, a liquid storage 25 for absorbing atomized liquid is provided in the second liquid storage chamber 211 of the atomizer 2, and the liquid storage 25 is in contact with the atomization core 22. In the specific implementation, the specific material of the liquid storage 25 can be a porous material such as liquid-conducting cotton, non-woven fabric, sponge, etc. that can absorb atomized liquid. With such arrangement, on the one hand, since the atomized liquid in the second liquid storage chamber 211 is adsorbed by the liquid storage 25, in some usage scenarios where the expansion chamber 1 pre-filled with atomized liquid and the atomizer 2 pre-filled with atomized liquid are assembled into one, the risk of leakage of the atomized liquid in the second liquid storage chamber 211 from the liquid injection hole 213 due to tipping over the atomizer 2 can be effectively reduced; on the other hand, the liquid storage 25 adsorbed with the atomized liquid is in contact with the atomizer core 22, so during the heating and atomization process of the atomizer core 22, the liquid storage 25 can supply the atomized liquid to the atomizer core 22 in a timely manner, thereby reducing the risk of the atomizer core 22 being dry-burned due to lack of liquid during the heating and atomization process.

[0075] For further information, please refer to Figure 7 , Fig.10 , Fig.15 as well as Fig.18 In some optional embodiments of the present invention, the volume of the second liquid storage chamber 211 of the atomizer 2 can be set to be less than or equal to the volume of the first liquid storage chamber 10 of the expansion chamber 1 (that is, the volume of the first liquid storage chamber 10 is greater than or equal to the volume of the second liquid storage chamber 211). Such a setting is equivalent to at least doubling the liquid storage capacity of the atomizer 2, so that the atomizer 2 can provide the user with a more sufficient number of inhalation puffs.

[0076] Correspondingly, please refer to Figure 1-19 The present utility model also provides an expansion chamber 1, which is used to be detachably assembled with the atomizer 2 in any of the above embodiments for use. Specifically, Figure 1-2 , Figure 11-12 as well as Fig.16 As shown, the expansion bin 1 provided in the embodiment of the utility model includes a first shell 11, in which a first liquid storage chamber 10 and a first air channel 114 separated from the first liquid storage chamber 10 are provided, a first suction nozzle 115 connected to the first air channel 114 is protrudingly provided on the first shell 11, and at least one liquid outlet pipe 12 connected to the first liquid storage chamber 10 is protrudingly provided on the side of the first shell 11 facing away from the first suction nozzle 115.

[0077] Among them, Figure 6-7 , Fig.10 , Fig.15 as well as Fig.18 As shown, when the second suction nozzle 23 is detached from the second shell 21 and the expansion chamber 1 and the atomizer 2 are assembled into one, the first air channel 114 of the expansion chamber 1 is connected with the second air channel 212 of the atomizer 2, and the corresponding liquid outlet pipe 12 is inserted into the corresponding liquid injection hole 213 and connected with the second liquid storage chamber 211 of the atomizer 2, so that the atomized liquid in the first liquid storage chamber 10 can be injected into the second liquid storage chamber 211 through each liquid outlet pipe 12.

[0078] In this embodiment, it should be noted that, in specific implementation, the number of the liquid outlet pipes 12 can be flexibly set according to actual needs, and can be one, two, or more than two. This embodiment does not impose specific restrictions on this. For example, Figure 2 , Fig.12 as well as Fig.16 As shown, the number of the liquid outlet pipes 12 can be set to two.

[0079] Based on the above structural design, the usage principle of the expansion bin 1 provided in this embodiment is as follows:

[0080] Please refer to Figure 3-7 As shown, before the expansion chamber 1 and the atomizer 2 are assembled into one body for use, the expansion chamber 1 can be inverted so that the liquid outlet port of the liquid outlet pipe 12 of the expansion chamber 1 is arranged upward (such as Figure 5As shown); then, the pre-prepared atomized liquid is injected into the first liquid storage chamber 10 of the expansion chamber 1 at the liquid outlet pipe 12. For example, the bottle mouth of the injection bottle storing the atomized liquid can be inserted into the liquid outlet port of the liquid outlet pipe 12, and then the atomized liquid in the injection bottle can be injected into the first liquid storage chamber 10 of the expansion chamber 1 by squeezing the bottle body of the injection bottle; then, the second suction nozzle 23 of the atomizer 2 is removed from the second shell 21 of the atomizer 2, and then the expansion chamber 1 pre-filled with the atomized liquid is assembled with the atomizer 2 at the injection hole 213 of the atomizer 2, so that the first liquid storage chamber 10 of the expansion chamber 1 can be connected with the atomizer 2 through the liquid outlet pipe 12. The second liquid storage chamber 211 of the atomizer 2 is connected, and the first air channel 114 of the expansion chamber 1 is connected to the second air channel 212 of the expansion chamber 1. In this way, during the atomization operation of the atomizer 2, as the atomized liquid in the second liquid storage chamber 211 of the atomizer 2 is gradually consumed by the atomization core 22, the atomized liquid in the first liquid storage chamber 10 can be injected into the second liquid storage chamber 211 through each liquid outlet pipe 12 for replenishment. At the same time, the aerosol generated by the atomization operation of the atomizer 2 can flow out to the user's mouth through the second air channel 212, the first air channel 114 and the first suction nozzle 115 in turn and be inhaled by the user.

[0081] It can be seen that in the technical solution of the present embodiment, by specially matching the atomizer 2 with an expansion chamber 1 that can be used in conjunction with the atomizer 2, the liquid storage capacity of the atomizer 2 can be expanded without changing the volume of the second liquid storage chamber 211 of the atomizer 2, so that the atomizer 2 can provide the user with more puffs and the atomizer 2 can be reused without replacement, thereby reducing the user's usage cost.

[0082] For further information, please refer to Figure 7 , Fig.10 , Fig.15 as well as Fig.18In some optional embodiments of the utility model, the liquid storage capacity of the expansion chamber 1 can be set to 1.5 to 15 times the liquid storage capacity of the atomizer 2, that is, assuming that the volume of the first liquid storage chamber 10 of the expansion chamber 1 is V1, and the volume of the second liquid storage chamber 211 of the atomizer 2 is V2, then 1.5V2≤V1≤15V2, specifically, assuming V2=2ML, then 3ML≤V1≤30ML. With such a configuration, compared with the method of directly replenishing the atomizer 2 with a liquid storage bottle, the technical solution of this embodiment can effectively reduce the number of times the user replenishes the atomizer 2 with atomizer liquid during the user's use of the atomizer 2 for suction, that is, the user does not need to frequently perform liquid filling operations on the atomizer 2. To facilitate understanding of the technical solution of the present embodiment, some specific usage scenarios are used as examples for relevant explanations. For example, assuming that the liquid storage capacity of the atomizer 2 is fixed at 2ML, and the liquid storage capacity of the expansion chamber 1 is 10ML, when a user is out for five days of inhalation use, 8ML of atomized liquid is needed. After the atomized liquid in the atomizer 2 is consumed, if a liquid storage bottle is used to directly replenish the atomizer 2 with atomized liquid, the user needs to carry the liquid storage bottle with him and perform three liquid filling operations on the atomizer 2 through the liquid storage bottle during the five days of inhalation use; and if the expansion chamber 1 is used to replenish the atomizer 2 with atomized liquid, the user only needs to perform one liquid filling operation on the expansion chamber 1 through the liquid storage bottle before going out to meet the user's inhalation use needs for at least five days, and there is no need to carry a liquid storage bottle with him, thereby effectively reducing the number of times the user replenishes the atomizer 2 with atomized liquid, which is beneficial to improving the user's usage experience.

[0083] For further information, please refer to Figure 2 , Figure 7 , Fig.12 , Fig.15 , Fig.16 and Fig.19 In some optional embodiments of the present invention, a connecting portion 116 disposed around each liquid outlet pipe 12 is convexly provided on the side of the first housing 11 facing away from the first suction nozzle 115, and the connecting portion 116 is used to be detachably connected to the second housing 21 of the atomizer 2. In this embodiment, the arrangement of the connecting portion 116 can facilitate the detachable assembly of the expansion chamber 1 and the atomizer 2 into one piece for use, for example, the expansion chamber 1 can be quickly assembled into one piece with the top of the second housing 21 by docking for use.

[0084] For further information, please refer to Figure 2 , Figure 5 , Figure 7 , Fig.12 , Fig.14 , Fig.15 as well as Figure 18-19In some optional embodiments of the utility model, in order to facilitate the detachable connection between the connecting portion 116 and the second housing 21 of the atomizer 2, at least one card slot 1160 is recessed on the inner wall of the connecting portion 116, and the card slot 1160 is used for snap connection with the second housing 21 of the atomizer 2. It can be understood here that in some specific application scenarios, the outer wall of the second housing 21 of the atomizer 2 is provided with a card slot 214 adapted to the card slot 1160. When the expansion chamber 1 and the atomizer 2 are assembled into one, the card slot 214 of the atomizer 2 will be snapped into the card slot 1160 of the expansion chamber 1, thereby realizing the snap connection between the expansion chamber 1 and the atomizer 2, so that the expansion chamber 1 and the atomizer 2 can be firmly assembled together for use without being easily separated from each other.

[0085] It should be noted here that, in some alternative embodiments, in order to facilitate the detachable connection between the connecting portion 116 and the second shell 21 of the atomizer 2, at least one clamping portion may be convexly provided on the inner wall of the connecting portion 116, and the clamping portion is used to be snap-connected with the second shell 21. Specifically, the outer wall of the second shell 21 of the atomizer 2 is provided with a groove adapted to the clamping portion. When the expansion bin 1 and the atomizer 2 are assembled into one, the clamping portion will be snapped into the groove of the second shell 21. In some other alternative embodiments, in order to facilitate the detachable connection between the connecting portion 116 and the second shell 21 of the atomizer 2, the connecting portion 116 is made of a magnetic conductive material (such as iron, iron alloy, cobalt, nickel, etc.), and the connecting portion 116 is used to be magnetically connected with the second shell 21 of the atomizer 2. Specifically, the outer wall of the second shell 21 of the atomizer 2 is provided with a magnet. When the expansion bin 1 and the atomizer 2 are assembled into one, the connecting portion 116 and the outer wall of the second shell 21 are attracted.

[0086] For further information, please refer to Figure 2 , Figure 5 as well as Figure 7-10 In some optional embodiments of the utility model, a first magnetic part 13 spaced apart from each liquid outlet pipe 12 is fixed to the side of the first shell 11 facing away from the first suction nozzle 115, and the first magnetic part 13 is used to be magnetically connected to the electronic atomization device, wherein the electronic atomization device includes the aforementioned atomizer 2 and a power supply host 3 connected to the atomizer 2, and the power supply host 3 is provided with a second magnetic part 31 for attracting the first magnetic part 13. In this way, in some scenarios where the expansion bin 1 of this embodiment is assembled into one body for use with the electronic atomization device provided with the second magnetic part 31, the magnetic attraction between the first magnetic part 13 and the second magnetic part 31 can be used to make the expansion bin 1 and the electronic atomization device more firmly assembled together for use without being easily separated from each other.

[0087] In this embodiment, it should be noted that, in the specific implementation, in some optional embodiments, one of the first magnetic component 13 and the second magnetic component 31 is a magnet, and the other is an object made of a magnetic conductive material, for example, it can be a metal sheet or a metal block made of a magnetic conductive material such as iron, iron alloy, cobalt, nickel, etc.; in other optional embodiments, the first magnetic component 13 and the second magnetic component 31 are both magnets, as long as the first magnetic component 13 and the second magnetic component 31 can attract each other, this embodiment does not impose any specific restrictions on the specific structural form of the first magnetic component 13 and the second magnetic component 31.

[0088] In some other optional embodiments of the present invention, the structure of the expansion bin 1 may also be as follows:

[0089] For details, please refer to Figure 11-15 The first shell 11 includes a first shell portion 111 and a second shell portion 112. The first shell portion 111 is provided with a first airway 114 and a first cavity 1110 separated from the first airway 114. The first suction nozzle 115 is provided at the top of the first shell portion 111. Each liquid outlet pipe 12 is provided at the bottom of the first shell portion 111 and communicates with the first cavity 1110. The connecting portion 116 is provided at the bottom of the first shell portion 111 and surrounds each liquid outlet pipe 12. The second shell portion 112 is strip-shaped and its top is connected to the side wall of the first shell portion 111 as a whole. A second cavity 1120 is arranged in the second shell portion 112. The second cavity 1120 is connected with the first cavity 1110 to form a first liquid storage cavity 10. A through hole 1121 connected with the first cavity 1110 is opened at the bottom of the second shell portion 112. A detachable sealing plug 14 is sealed at the through hole 1121. The sealing plug 14 can be a silicone plug, a rubber plug, etc.

[0090] In this embodiment, based on the above structural design, in addition to the aforementioned operation method of assembling the expansion bin 1 and the atomizer 2 of this embodiment into one body for use, the expansion bin 1 of this embodiment can also be used as follows:

[0091] When in use, the expansion chamber 1 can be directly assembled with the atomizer 2 at the injection hole 213 of the atomizer 2; then the expansion chamber 1 is inverted together with the atomizer 2, so that the through hole 1121 located at the bottom of the expansion chamber 1 is set upward; then the sealing plug 14 is removed to expose the through hole 1121 located at the bottom of the expansion chamber 1 (if the through hole 1121 is originally exposed, this operation is not required); then the pre-prepared atomized liquid is injected into the second cavity 1120 of the expansion chamber 1 at the through hole 1121 until the second cavity 1120 is filled with the atomized liquid or is nearly filled with the atomized liquid; finally, the sealing plug 14 is inserted into the through hole 1121 for sealing to complete the liquid injection process of the expansion chamber 1.

[0092] In this embodiment, it can be understood that after the atomized liquid in the second liquid storage chamber 211 of the atomizer 2 and the first cavity 1110 of the first shell 111 is consumed, the user can replenish the atomized liquid in the second shell 112 into the second liquid storage chamber 211 of the atomizer 2 by tilting the expansion chamber 1.

The third shell 113 and the second shell 112 are arranged perpendicular to each other and are relatively spaced apart from the bottom of the first shell 111. The third shell 113 is provided with a through hole 1130 which is relatively spaced apart from the connecting portion 116 of the expansion bin 1. The through hole 1130 is used for the electronic atomization device to pass through. Specifically, the electronic atomization device includes a power host 3 and the aforementioned atomizer 2 connected to the upper end of the power host 3. When the expansion bin 1 of this embodiment is assembled into one with the electronic atomization device, the atomizer 2 and the power host 3 successively pass through the through hole 1130 of the third shell 113 until the top of the atomizer 2 is connected to the connecting portion 116 of the expansion bin 1 as an integral whole (at this time, the bottom of the power host 3 is located in the through hole 1130), thereby completing the assembly between the expansion bin 1 and the electronic atomization device.

[0094] Furthermore, considering that in some specific application scenarios, the injection hole 213 of the atomizer 2 is also sealed and connected with a sealing member 24 (such as a sealing film) in the form of a sealing film. Figure 3-4 As shown), based on this application scenario, in order to facilitate the liquid outlet pipe 12 of the expansion bin 1 to pierce the seal 24 at the injection hole 213 and communicate with the second liquid storage chamber 211 of the atomizer 2 when the expansion bin 1 and the atomizer 2 are assembled into one for use, in some optional embodiments of the utility model, such as Figure 2 and Figure 7 As shown, the end of the liquid outlet tube 12 away from the first liquid storage chamber 10 is a tip, that is, the lower end of the liquid outlet tube 12 is a tip.

Thanks to the improvement of the above atomizer 2, the electronic atomization device of this embodiment has the same technical effect as the above atomizer 2, which will not be repeated here. It should be noted here that in the specific implementation, the connection between the atomizer 2 and the power host 3 can be a detachable connection (for example, a magnetic connection, a snap connection, a threaded connection, etc.), or a non-detachable fixed connection, which can be determined according to actual needs, and this embodiment does not make specific limitations on this.
