Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device and a liquid injection method for the electronic atomization device. Background Technology

[0002] Electronic atomizing devices, as alternatives to traditional cigarettes, typically include a fluid cup, a seal, an atomizer coil, and a mouthpiece. The fluid cup contains an atomizing chamber, an outlet channel connecting to the atomizing chamber, and a reservoir for storing the atomized liquid. The fluid cup has an opening connecting to the reservoir. The seal is located at the opening of the fluid cup. The atomizer coil is disposed within the atomizing chamber and is in fluid communication with the reservoir. The atomizer coil heats the atomized liquid, thereby forming an inhalable aerosol within the atomizing chamber that leads to the outlet channel. The mouthpiece is located at the opening of the fluid cup and has a draw port connected to the outlet channel.

[0003] In related technologies, when injecting liquid into the reservoir, a single injection hole is usually provided on the oil cup or sealing element. After the reservoir is filled with atomizing liquid, the nozzle is placed over the opening of the oil cup. During the injection process, the space inside the reservoir is gradually filled with atomizing liquid. To balance the internal and external air pressure of the reservoir, an exhaust channel must be provided to expel the air from the reservoir; otherwise, the atomizing liquid cannot fill the reservoir completely. When using a single injection hole, the gap between the injection needle and the wall of the injection hole is usually used as the exhaust channel. To seal the injection hole after injection, a sealing post is usually provided on the nozzle. After the nozzle is placed over the opening of the oil cup, the sealing post can be inserted into the injection hole to seal it. However, during the insertion of the sealing post into the injection hole, the air pressure inside the reservoir increases, forcing some atomizing liquid into the atomizing core. When the atomizing liquid squeezed into the atomizing core exceeds the maximum liquid capacity of the atomizing core, leakage will occur. Furthermore, when the gap between the injection needle and the wall of the injection orifice serves as the venting channel, there is a risk of blockage if atomized liquid adheres to the injection needle. To reduce this risk, the size of the injection orifice is typically increased to create a larger gap between the injection needle and the orifice wall. However, increasing the orifice size also necessitates increasing the size of the sealing post used to seal it. This increases the amount of atomized liquid forced into the atomizing core when the sealing post is inserted, thus increasing the risk of leakage. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an electronic atomizing device and a liquid injection method for the electronic atomizing device, which helps to reduce the amount of atomizing liquid squeezed into the atomizing core during assembly, thereby reducing the risk of leakage.

[0005] An electronic atomizing device according to a first aspect of this application includes: a housing having a liquid storage chamber having an opening at one end of the housing for liquid injection; a mouthpiece assembly including a mouthpiece, a seal, and a movable member integrally assembled thereon, the seal being movable relative to the mouthpiece in a longitudinal direction, the seal being used to block the opening and having a through hole for venting; the movable member being movably disposed between the mouthpiece and the seal, the movable member having a first working position for restricting the longitudinal movement of the seal relative to the mouthpiece and a second working position for releasing the restriction; the mouthpiece having a sealing portion that is capable of blocking the through hole when the movable member is in the second working position; and a driving structure for driving the movable member from the first working position to the second working position.

[0006] The electronic atomizing device according to the first aspect of this application has at least the following beneficial effects: During assembly, liquid is first injected into the liquid storage chamber through the opening of the liquid storage chamber. After the injection is completed, the nozzle assembly, which is pre-assembled as a single unit and consists of a nozzle, a seal, and a movable part, is assembled at the opening of the liquid storage chamber. When the nozzle, seal, and movable part are pre-assembled as a single unit, the movable part is ensured to be in a first working position. During the process of applying force to the nozzle assembly to seal the opening of the liquid storage chamber, since the movable part is in the first working position, the relative longitudinal movement of the nozzle and the seal is restricted, preventing the sealing portion on the nozzle from temporarily blocking the through hole. This allows exhaust through the through hole, thereby reducing the amount of atomized liquid squeezed into the atomizing core during assembly. During the process of the seal blocking the opening of the liquid storage chamber, or after the seal blocks the opening, the movable part is moved from the first working position to the second working position by a driving structure to release the restriction, thereby allowing the sealing portion on the nozzle to block the through hole after the seal blocks the opening of the liquid storage chamber. In the above assembly process, the through hole is only used for venting, that is, there is no need to inject liquid through the through hole in conjunction with the injection needle. Compared with the existing technology, there is no need to consider the situation where the gap between the injection needle and the inner wall of the through hole is blocked by the atomized liquid during the injection process. Therefore, the size of the through hole can be reduced, which helps to reduce the amount of atomized liquid squeezed into the atomizing core during the sealing process of the through hole, thereby reducing the risk of leakage.

[0007] According to some embodiments of this application, the suction nozzle is provided with a first limiting part, the movable part is provided with a first clearance through hole, and the sealing member is provided with a clearance groove. The first limiting part can pass through the first clearance through hole and be inserted into the clearance groove when the movable part is in the second working position. The first limiting part can abut against the movable part when the movable part is in the first working position to restrict the sealing member from moving longitudinally relative to the suction nozzle.

[0008] According to some embodiments of this application, the through hole includes an exhaust section away from the liquid storage chamber and a sealing section close to the liquid storage chamber. The diameter of the exhaust section is larger than the diameter of the sealing section, and the sealing section is used to cooperate with the sealing part to block the through hole.

[0009] According to some embodiments of this application, the movable part is provided with a second clearance through hole, and the sealing part can pass through the second clearance through hole and block the through hole when the movable part is in the second working position.

[0010] According to some embodiments of this application, the second clearance through hole is elongated so that the sealing part can pass through the second clearance through hole when the movable member is in the first working position.

[0011] According to some embodiments of this application, the driving structure includes a pushing part disposed on the housing and protruding longitudinally from the opening. The movable part includes a main body and a force-receiving part disposed at one end of the main body and extending outward and obliquely upward. The pushing part is used to act on the force-receiving part when the nozzle assembly is assembled at the opening to drive the movable part from the first working position to the second working position.

[0012] According to some embodiments of this application, the seal is provided with an assembly groove, the main body is disposed in the assembly groove, and the main body can move from the first working position to the second working position within the assembly groove.

[0013] According to some embodiments of this application, a positioning structure is provided between the seal and the main body, the positioning structure being used to position at least one of the first working position and the second working position.

[0014] According to some embodiments of this application, the positioning structure includes a locking block and a locking slot, one of which is disposed on the main body and the other is disposed on the sealing member, and the locking block and the locking slot can cooperate with each other to position the second working position.

[0015] According to some embodiments of this application, the sealing element is provided with a second limiting part, and the main body is provided with a first mating part that cooperates with the second limiting part for limiting. The first mating part and the second limiting part can cooperate with each other to position the first working position.

[0016] According to some embodiments of this application, the card block is disposed on the seal, the card groove is disposed at one end of the main body away from the force-bearing part, the first mating part is disposed at one end of the main body close to the force-bearing part, and a second mating part is disposed at one end of the main body away from the force-bearing part to cooperate and limit the card block. The second mating part is located on the side of the card groove away from the force-bearing part, and the second mating part and the card block can cooperate with each other to position the first working position.

[0017] The liquid injection method of the electronic atomizing device according to the second aspect embodiment of this application, which is applied to the electronic atomizing device according to the first aspect embodiment of this application, includes the following steps:

[0018] A preset amount of atomizing liquid is injected into the liquid storage chamber through the opening;

[0019] The sealing element is used to seal the opening, and the moving part is driven from the first working position to the second working position by the driving structure. Finally, the sealing part is driven to seal the through hole so that the nozzle assembly can be assembled into the opening.

[0020] An electronic atomizing device according to a third aspect of this application includes: a housing having a liquid storage chamber having an opening at one end of the housing for liquid injection; a mouthpiece assembly including an integrally assembled mouthpiece, a seal, and a movable member, the seal being used to block the opening and having a through hole for venting, the movable member being movably disposed between the mouthpiece and the seal, the movable member having a third working position for avoiding the through hole and a fourth working position for blocking the through hole; and a driving structure for driving the movable member to move from the third working position to the fourth working position.

[0021] The electronic atomizing device according to the third aspect of this application has at least the following beneficial effects: During assembly, liquid is first injected into the liquid storage chamber through the opening of the storage chamber. After the injection is completed, the nozzle assembly, which is pre-assembled as a single unit and consists of a nozzle, a seal, and a movable part, is assembled at the opening of the liquid storage chamber. When the nozzle, seal, and movable part are pre-assembled as a single unit, the movable part is ensured to be in the third working position. During the process of applying force to the nozzle assembly to seal the opening of the liquid storage chamber, since the movable part does not move to the fourth working position, exhaust can be achieved through the through hole, thereby reducing the amount of atomizing liquid squeezed into the atomizing core during assembly. During the process of the seal sealing the opening of the liquid storage chamber, or after the seal seals the opening of the liquid storage chamber, the movable part can be moved from the third working position to the fourth working position by a driving structure to seal the through hole. In the above assembly process, the through hole is only used for venting, that is, there is no need to inject liquid through the through hole in conjunction with the injection needle. Compared with the prior art, there is no need to consider the situation where the gap between the injection needle and the inner wall of the through hole is blocked by the atomized liquid during the injection. In addition, by using the movable part to seal the through hole, compared with the prior art, there is no need to consider the leakage problem caused by the atomized liquid in the storage chamber being squeezed into the atomizing core when the sealing column is inserted into the through hole, which helps to reduce the risk of leakage.

[0022] The liquid injection method of the electronic atomizing device according to the fourth aspect embodiment of this application, which is applied to the electronic atomizing device according to the third aspect embodiment of this application, includes the following steps:

[0023] A preset amount of atomizing liquid is injected into the liquid storage chamber through the opening;

[0024] The sealing element is used to seal the opening, and the moving part is driven by the driving structure to move from the third working position to the fourth working position to seal the through hole, so as to assemble the nozzle assembly into the opening.

[0049] Reference Figures 1 to 12 An electronic atomizing device according to an embodiment of this application includes a housing 100, a mouthpiece assembly, and a drive structure.

[0050] Specifically, the housing 100 has a liquid storage chamber 110 for storing atomizing liquid. The liquid storage chamber 110 has an opening 120 located at one end of the housing 100 for liquid injection. The nozzle assembly is assembled at the opening 120. The nozzle assembly includes an integrally assembled nozzle 210, a seal 220, and a movable member 230. The seal 220 is movable relative to the nozzle 210 in the longitudinal direction. The seal 220 is used to seal the opening 120 and has a through hole 221 for venting. The movable member 230 is movably disposed between the nozzle 210 and the seal 220. The component 230 has a first working position for restricting the longitudinal movement of the seal 220 relative to the nozzle 210 and a second working position for releasing the restriction. The nozzle 210 is provided with a sealing part 211 for blocking the through hole 221. The sealing part 211 can block the through hole 221 when the movable component 230 is in the second working position. A drive structure is provided in at least one of the housing 100, the nozzle 210, and the seal 220. The drive structure is used to drive the movable component 230 from the first working position to the second working position when the nozzle assembly is assembled at the opening 120.

[0051] It should be noted that the vertical direction mentioned above refers to the X direction in the attached diagram.

[0052] During assembly, liquid is first injected into the storage chamber 110 through the opening 120. After the injection is completed, the nozzle assembly, which is pre-assembled as a single unit consisting of the nozzle 210, the seal 220, and the movable part 230, is assembled at the opening 120. When the nozzle 210, the seal 220, and the movable part 230 are pre-assembled, the movable part 230 is ensured to be in the first working position. During the process of applying force to the nozzle assembly to seal the opening 120 with the seal 220, the movable part 230, being in the first working position, restricts the relative longitudinal movement of the nozzle 210 and the seal 220. This prevents the sealing part 211 on the nozzle 210 from temporarily blocking the through hole 221, allowing air to escape through the through hole 221. This, in turn, helps reduce the amount of atomizing liquid squeezed into the atomizing core during assembly. During the process of sealing the opening 120 with the seal 220, or after the seal 220 seals the opening 120, the moving part 230 is moved from the first working position to the second working position by the driving structure to release the restriction, so that the sealing part 211 provided on the nozzle 210 can seal the through hole 221 after the seal 220 seals the opening 120. In the above assembly process, the through hole 221 is only used for venting, that is, there is no need to inject liquid through the through hole 221 in conjunction with the injection needle. Compared with the prior art, there is no need to consider the situation that the gap between the injection needle and the inner wall of the through hole 221 is blocked by the atomized liquid during the injection. Therefore, the size of the through hole 221 can be reduced, which helps to reduce the atomized liquid squeezed into the atomizing core during the process of sealing the through hole 221 with the seal 220, thereby helping to reduce the risk of leakage.

[0053] It should be noted that in some embodiments, the movable member 230 is movably disposed between the suction nozzle 210 and the sealing member 220 and is capable of moving in a direction intersecting the longitudinal direction.

[0054] Specifically, the movable component 230 is movably disposed between the mouthpiece 210 and the seal 220 and is capable of moving in a direction perpendicular to the longitudinal direction. In some embodiments, the electronic atomizing device has a first direction and a second direction perpendicular to the longitudinal direction, the first direction and the second direction intersecting each other. The electronic atomizing device has a first dimension along the first direction and a second dimension along the second direction, the first dimension being larger than the second dimension. A drive structure is used to drive the movable component 230 to move along the first direction to ensure that the movable component 230 has sufficient movement space. In other embodiments, the drive structure is used to drive the movable component 230 to move along the second direction, or the first dimension is equal to or smaller than the second dimension.

[0055] It should be noted that in some of the embodiments, the movable member 230 can be a sheet structure made of a rigid material, such as a metal sheet made of a rigid metal material. For example, the metal sheet can be a steel sheet.

[0056] Reference Figures 1 to 6 In some embodiments, the nozzle 210 has a receiving cavity 212, and the seal 220 is embedded in the receiving cavity 212.

[0057] Reference Figures 1 to 7 In some embodiments, the suction nozzle 210 is provided with a first limiting part 213, the movable member 230 is provided with a first clearance through hole 2311 for passing through the first limiting part 213, and the sealing member 220 is provided with a clearance groove 222 for inserting the first limiting part 213. The first limiting part 213 can pass through the first clearance through hole 2311 and be inserted into the clearance groove 222 when the movable member 230 is in the second working position. The first limiting part 213 can abut against the movable member 230 when the movable member 230 is in the first working position. At this time, the first limiting part 213 and the first clearance through hole 2311 are misaligned to restrict the sealing member 220 from moving longitudinally relative to the suction nozzle 210. Its structure is simple and easy to implement.

[0058] Reference Figures 1 to 6In some embodiments, the through hole 221 includes an exhaust section 221a away from the liquid storage chamber 110 and a sealing section 221b close to the liquid storage chamber 110. The diameter of the exhaust section 221a is larger than the diameter of the sealing section 221b. The sealing section 221b is used to cooperate with the sealing part 211 to seal the through hole 221. During assembly, the sealing part 211 provided on the nozzle 210 is first inserted into the exhaust section 221a. That is, after the sealing part 211 is inserted into the through hole 221, it does not immediately seal the through hole 221, but can exhaust air through the gap between the sealing part 211 and the hole wall of the exhaust section 221a. The sealing of the through hole 221 is completed only when the sealing part 211 is inserted into the sealing section 221b. This helps to further reduce the atomizing liquid squeezed into the atomizing core during the process of the sealing part 211 sealing the through hole 221.

[0059] Specifically, the sealing section 221b is used to press against the sealing part 211 to seal the through hole 221.

[0060] Reference Figures 1 to 6 In some embodiments, the diameter of the exhaust section 221a decreases from the end of the exhaust section 221a away from the sealing section 221b to the end of the exhaust section 221a closer to the sealing section 221b, giving the exhaust section 221a a certain guiding effect, thereby allowing the sealing part 211 to be smoothly inserted into the sealing section 221b. In addition, after the movable part 230 moves to the second working position to release the restriction, the sealing part 211 can gradually move from the exhaust section 221a to the sealing section 221b until it is inserted into the sealing section 221b to completely seal the through hole 221. This can prevent the sealing part 211 from sealing the through hole 221 too quickly, which helps to avoid leakage caused by air inside the through hole 221 being unable to be discharged in time and squeezing the atomizing liquid in the liquid storage chamber 110 into the atomizing core.

[0061] Reference Figures 1 to 7 In some embodiments, the movable member 230 is provided with a second clearance through hole 2312 for the sealing part 211 to pass through. The sealing part 211 can pass through the second clearance through hole 2312 and block the through hole 221 when the movable member 230 is in the second working position. During assembly, the second clearance through hole 2312 can play a positioning role.

[0062] Reference Figure 6 and Figure 7 In some embodiments, the second clearance through-hole 2312 is elongated so that the sealing part 211 can pass through the second clearance through-hole 2312 when the movable part 230 is in the first working position. During assembly, the sealing part 211 is always disposed within the second clearance through-hole 2312, wherein the second clearance through-hole 2312 is elongated so that the sealing part 211 does not interfere with the movement of the movable part 230 relative to the sealing part 220.

[0063] It should be noted that in some other embodiments, the sealing part 211 can abut against the movable part 230 when the movable part 230 is in the first working position. At this time, the sealing part 211 is misaligned with the second clearance through hole 2312 to restrict the sealing part 220 from moving longitudinally relative to the suction nozzle 210. Based on this, the first limiting part 213 and the first clearance through hole 2311 mentioned above can be provided, or the first limiting part 213 and the first clearance through hole 2311 can be omitted. This is not limited here.

[0064] Reference Figures 1 to 7 In some embodiments, the drive structure includes a pushing part 130, which is disposed on the housing 100 and protrudes longitudinally from the opening 120. The movable part 230 includes a main body 231 and a force-receiving part 232, which is disposed at one end of the main body 231 and extends outward and obliquely upward. The pushing part 130 is used to act on the force-receiving part 232 when the nozzle assembly is assembled at the opening 120, so as to drive the movable part 230 to move from a first working position to a second working position. During the process of sealing the opening 120 with the seal 220, the pushing part 130 acts on the force receiving part 232 to make the movable part 230 gradually move from the first working position to the second working position. After the seal 220 seals the opening 120, the movable part 230 moves to the second working position to release the restriction, so that the suction nozzle 210 can move relative to the seal 220 in the longitudinal direction, thereby enabling the sealing part 211 provided on the suction nozzle 210 to seal the through hole 221.

[0065] Reference Figures 1 to 7 In some embodiments, the seal 220 is provided with a third clearance through hole 223 for the pushing part 130 to pass through. The pushing part 130 is used to pass through the third clearance through hole 223 and act on the force receiving part 232 when the nozzle assembly is installed at the opening 120, so as to drive the movable part 230 from the first working position to the second working position. On the one hand, the third clearance through hole 223 can play a positioning role when the seal 220 is installed. On the other hand, the hole wall of the third clearance through hole 223 can play a supporting and protective role during the process of the pushing part 130 acting on the force receiving part 232, which helps to prevent the pushing part 130 from breaking due to the reaction force.

[0066] Reference Figure 6 and Figure 7 In some embodiments, the first clearance through hole 2311 and the second clearance through hole 2312 are both provided on the main body 231.

[0067] It should be noted that in some other embodiments, the second clearance through hole 2312 may not be provided, and this is not a limitation here. Specifically, whether the movable member 230 is in the first working position or the second working position, it will not block the through hole 221, that is, the movable member 230 moving to the second working position will not interfere with the sealing part 211 blocking the through hole 221.

[0068] It should be noted that in some other embodiments, the movable part 230 can also be manually driven to move by a manual button that is slidably disposed on the outer wall of the housing 100 and connected to the movable part 230, which is not limited here.

[0069] Reference Figure 7 In some embodiments, the seal 220 is provided with an assembly groove 224, and the main body 231 is disposed in the assembly groove 224. The main body 231 can move from a first working position to a second working position in the assembly groove 224. The assembly groove 224 can limit the activity area of ​​the movable part 230, which is beneficial to improving the stability and reliability of the movable part 230 during operation.

[0070] It should be noted that in some embodiments, a positioning structure is provided between the seal 220 and the main body 231, the positioning structure being used to position at least one of the first working position and the second working position.

[0071] Reference Figures 7 to 12 In some embodiments, the positioning structure includes a locking block 225 and a locking groove 2313. One of the locking block 225 and the locking groove 2313 is disposed on the main body 231, and the other is disposed on the seal 220. The locking block 225 and the locking groove 2313 can cooperate with each other to position the second working position. Specifically, when the movable member 230 moves to the second working position, the locking block 225 engages with the locking groove 2313 to position the second working position.

[0072] Reference Figures 7 to 12 In some embodiments, the seal 220 is provided with a second limiting portion 226, and the main body 231 is provided with a first mating portion 2314 that cooperates with and limits the second limiting portion 226. The first mating portion 2314 and the second limiting portion 226 can cooperate with each other to position the first working position. Specifically, when the movable member 230 moves to the first working position, the first mating portion 2314 and the second limiting portion 226 abut against each other to position the first working position. The engaging block 225 and the slot 2313 enable the positioning structure to position not only the second working position of the movable member 230 but also the first working position of the movable member 230.

[0073] Reference Figures 7 to 12In some embodiments, the locking block 225 is disposed on the seal 220, the locking groove 2313 is disposed at the end of the main body 231 away from the force-bearing part 232, the first mating part 2314 is disposed at the end of the main body 231 close to the force-bearing part 232, and the end of the main body 231 away from the force-bearing part 232 is provided with a second mating part 2315 that cooperates with and limits the locking block 225. The second mating part 2315 is located on the side of the locking groove 2313 away from the force-bearing part 232. The second mating part 2315 and the locking block 225 can cooperate with each other to position the first working position. When the movable part 230 moves to the first working position, the first mating part 2314 and the second limiting part 226 abut against each other to position the first working position. At the same time, the second mating part 2315 and the locking block 225 cooperate to limit the movable part 230. Before the sealing part 220 seals the opening 120, the movable part 230 can be limited to the first working position, which helps to improve the stability and reliability of the movable part 230 during operation.

[0074] Reference Figures 7 to 12 In some embodiments, both the locking block 225 and the slot 2313 are triangular, so that when the movable part 230 is moved by force, the locking block 225 can easily be locked into or disengaged from the slot 2313.

[0075] The liquid injection method of the electronic atomizing device according to the embodiments of this application, applied to the electronic atomizing device of the above embodiments, includes the following steps:

[0076] A preset amount of atomizing liquid is injected into the liquid storage chamber 110 through the opening 120;

[0077] The seal 220 is sealed in the opening 120, and the moving part 230 is driven from the first working position to the second working position by the drive structure. Finally, the sealing part 211 is driven to seal the through hole 221 so that the nozzle assembly can be assembled in the opening 120.

[0078] It should be noted that, in some embodiments, the movable part 230 may be in the first working position before the step of sealing the seal 220 into the opening 120.

[0079] An electronic atomizing device according to another embodiment of this application includes a housing 100, a mouthpiece assembly, and a drive structure.

[0080] Specifically, the housing 100 has a liquid storage chamber 110, which has an opening 120 located at one end of the housing 100 for liquid injection. The suction nozzle assembly includes a suction nozzle 210, a sealing member 220, and a movable member 230 assembled together. The sealing member 220 is used to block the opening 120 and has a through hole 221 for venting. The movable member 230 is movably disposed between the suction nozzle 210 and the sealing member 220. The movable member 230 has a third working position for avoiding the through hole 221 and a fourth working position for blocking the through hole 221. The driving structure is used to drive the movable member 230 to move from the third working position to the fourth working position.

[0081] During assembly, liquid is first injected into the storage chamber 110 through the opening 120. After injection, the nozzle assembly, consisting of the pre-assembled nozzle 210, seal 220, and movable part 230, is assembled at the opening 120. When assembling the nozzle 210, seal 220, and movable part 230, the movable part 230 is ensured to be in the third working position. During the process of applying force to the nozzle assembly to seal the opening 120 with the seal 220, since the movable part 230 does not move to the fourth working position, air can be released through the through hole 221, thereby reducing the amount of atomizing liquid squeezed into the atomizing core during assembly. During or after the seal 220 seals the opening 120, the movable part 230 is moved from the third working position to the fourth working position by a drive structure to seal the through hole 221. In the above assembly process, the through hole 221 is only used for venting, that is, there is no need to inject liquid through the through hole 221 in conjunction with the injection needle. Compared with the prior art, there is no need to consider the situation where the gap between the injection needle and the inner wall of the through hole 221 is blocked by the atomizing liquid during the injection process. In addition, by using the movable part 230 to seal the through hole 221, compared with the prior art, there is no need to consider the leakage problem caused by the atomizing liquid in the liquid storage chamber 110 being squeezed into the atomizing core when the sealing column is inserted into the through hole 221, which helps to reduce the risk of leakage.

[0082] In addition, the electronic atomizing device of the other embodiment described above can continue to use the driving structure and positioning structure of the electronic atomizing device of the above embodiment.

[0083] A liquid injection method for an electronic atomizing device according to another embodiment of this application, applied to the electronic atomizing device of the other embodiment described above, includes the following steps:

[0084] A preset amount of atomizing liquid is injected into the liquid storage chamber 110 through the opening 120;

[0085] The seal 220 is sealed in the opening 120, and the moving part 230 is moved from the third working position to the fourth working position by the drive structure to seal the through hole 221, so as to assemble the nozzle assembly in the opening 120.

[0086] It should be noted that, in some embodiments, the movable part 230 may be in the third working position before the step of sealing the seal 220 into the opening 120.
