[0002] This application claims priority to Chinese Utility Model Patent Application No. 2025211143021, filed on May 30, 2025, entitled "Liquid Storage Component, Atomizing Component and Electronic Atomizing Device", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic atomization technology, and in particular to a liquid storage component, an atomizing component, and an electronic atomization device. Background Technology

[0004] An electronic atomizing device is an electronic device that vaporizes stored e-liquid, medicinal liquid, or other atomizing liquid into vapor through electric heating or other methods. An electronic atomizing device typically includes a reservoir for storing the atomizing liquid and an atomizer core for absorbing the liquid and vaporizing it. For user convenience, the reservoir is usually pre-filled with atomizing liquid. However, because the reservoir and the atomizer core remain connected before use, changes in external air pressure during transport can easily cause the atomizing liquid to leak from the core, resulting in leakage even before the device is used.

[0005] In related technologies, to prevent leakage during transportation of electronic atomizing devices, a dedicated reservoir for storing the atomizing liquid can be provided. At the factory, the atomizing liquid is sealed and stored in the reservoir, while the reservoir cup with the atomizing coil is not pre-filled with atomizing liquid. This allows the reservoir and electronic atomizing device to be transported separately before use, thus preventing leakage during transport. When the user needs to use the device, the reservoir and electronic atomizing device are then assembled, allowing the pre-filled atomizing liquid to be transferred into the reservoir cup's storage space. However, this design still presents the following technical problems:

[0006] After assembling the reservoir and the e-cigarette device into one unit, in order to avoid the atomizer coil running dry due to lack of liquid, users need to wait until the atomizer coil absorbs the liquid in the reservoir until it becomes moist before they can start vaping. However, the process of the atomizer coil going from an empty state to a moist state is slow. As a result, even after assembling the reservoir and the e-cigarette device into one unit, users still need to wait a long time before they can start vaping, which undoubtedly reduces the user experience. Utility Model Content

[0007] The main objective of this application is to provide a liquid storage component, an atomizing component, and an electronic atomizing device, aiming to solve the technical problem in the related art where, after assembling a liquid storage container pre-filled with atomizing liquid and an electronic atomizing device without pre-filled atomizing liquid into one unit, the user needs to wait a long time before starting to use it for inhalation.

[0008] To achieve the above objectives, in a first aspect, this application provides an electronic atomizing device, which includes:

[0009] A liquid reservoir includes a first housing, a piston, and a flexible seal. The first housing has a first storage chamber for storing atomized liquid. The piston is at least partially slidably fitted within the first housing and has a guide hole for discharging the atomized liquid from the first storage chamber.

The slide rail portion slides in a one-to-one correspondence with each of the slide grooves. The first housing is also provided with a mist outlet channel. The top of the first housing is provided with a mouthpiece that communicates with the mist outlet channel. The first housing is provided with an inner tube portion. The inner tube portion has at least a portion of the mist outlet channel. The end of the inner tube portion away from the mouthpiece is inserted into the mounting hole. The outer peripheral wall of the inner tube portion is in elastic contact with the inner wall of the mounting hole. The first housing, the inner tube portion, and the sealing plug together define the first storage cavity. When the electronic atomizing device is in the second state, the mist outlet channel is connected to the atomizing channel, and the first housing is connected to the second housing.

[0018] In some embodiments, when the electronic atomizing device is in the first state, the first storage cavity contains atomizing liquid, and the second storage cavity does not contain atomizing liquid.

[0019] In some embodiments, when the electronic atomizing device is in the second state, the first housing and the second housing are detachably connected.

[0020] In some embodiments, the second end of the liquid guide tube has a pointed structure.

[0021] In some embodiments, the atomizing body further includes a third housing, a battery, and a control circuit board. The third housing is connected to the second housing, and the battery and the control circuit board are both installed inside the third housing. The control circuit board is electrically connected to the battery and the atomizing core, respectively.

[0022] In some embodiments, the pusher further includes a cup portion disposed within the second housing, the pusher being connected to the top end of the cup portion, the atomizing body further includes a base located within the second housing and an air duct having at least a portion of the atomizing channel, the base being sealed to the bottom end of the cup portion, one end of the air duct being sealed to the pusher and the other end being sealed to the base, the cup portion, the pusher, the air duct and the base together defining the second storage cavity, the side wall of the air duct being provided with at least one liquid inlet hole communicating with the second storage cavity, the atomizing core being installed inside the air duct and the outer wall of the atomizing core covering each of the liquid inlet holes.

[0024] In some embodiments, a gap exists between the outer wall of the liquid storage and the cavity wall of the second storage chamber to form an exhaust channel. The inner wall of the pusher is provided with a venting groove located above the liquid storage. One end of the venting groove is connected to the exhaust channel, and the other end is connected to the atomization channel. The side wall of the liquid storage is provided with a through groove extending along the height direction of the liquid storage. One end of the through groove penetrates the top surface of the liquid storage and the other end penetrates the bottom surface of the liquid storage. The first end of the liquid guide tube extends into the through groove, and the first end face of the liquid guide tube, the inner wall of the through groove, and the cavity wall of the second storage chamber together define a sealed space.

[0025] In some embodiments, the flexible seal includes a first sealing portion and a second sealing portion, the liquid guiding hole includes a first hole portion and a second hole portion spaced apart, and the liquid guiding tube includes a first pipe portion and a second pipe portion spaced apart. The first sealing portion seals the first hole portion, and the second sealing portion seals the second hole portion. The first end of the first pipe portion and the first end of the second pipe portion are both connected to the second storage cavity. When the electronic atomizing device is in the first state, the second end of the first pipe portion is sealed and fitted inside the first hole portion and is positioned opposite to the first sealing portion, and the second end of the second pipe portion is sealed and fitted inside the second hole portion and is positioned opposite to the second sealing portion. When the electronic atomizing device is changed from the first state to the second state, the second end of the first pipe portion pierces the first sealing portion and is connected to the first storage cavity, and the second end of the second pipe portion pierces the second sealing portion and is connected to the first storage cavity.

[0027] In some embodiments, the second end port of the second pipe portion is at least partially located within the second hole portion.

[0028] In some embodiments, the second end face of the first pipe portion includes a first inclined surface, a first longitudinal surface, and a first stepped surface. The first inclined surface is connected to the first stepped surface through the first longitudinal surface. The first longitudinal surface divides the second end port of the first pipe portion into two parts. The included angle between the first longitudinal surface and the first stepped surface is 80° to 100°. Along the axial direction of the first pipe portion, the first inclined surface is higher than the first stepped surface. The second end face of the second pipe portion includes a second inclined surface, a second longitudinal surface, and a second stepped surface. The second inclined surface is connected to the second stepped surface through the second longitudinal surface. The second longitudinal surface divides the second end port of the second pipe portion into two parts.

Along the axial direction of the second pipe portion, the second inclined surface is higher than the second stepped surface. Along the height direction of the pusher, the first stepped surface is higher than the second stepped surface.

[0029] Secondly, this application also provides a liquid storage component for use in combination with the atomizing body in the electronic atomizing device described in any of the above embodiments, wherein the liquid storage component is the liquid reservoir in the electronic atomizing device described in any of the above embodiments.

[0030] Thirdly, this application also provides an atomizing component for use in combination with the liquid reservoir in the electronic atomizing device described in any of the above embodiments, wherein the atomizing component is the atomizing body in the electronic atomizing device described in any of the above embodiments.

[0031] Compared with the prior art, this application has at least the following beneficial effects:

[0032] In the technical solution provided in this application embodiment, by designing an independent liquid reservoir and atomizing body, the liquid reservoir can be combined with the atomizing body to form an electronic atomizing device with a first state and a second state. In specific applications, the first storage chamber of the liquid reservoir can be pre-filled with atomizing liquid, while the second storage chamber of the atomizing body can be left unfilled. Thus, on the one hand, since the liquid guide hole of the liquid reservoir is sealed by a flexible seal, when transporting the electronic atomizing device, whether the liquid reservoir and atomizing body are transported separately or combined into the first state electronic atomizing device before transport, no leakage problem will occur. On the other hand, since the liquid reservoir has a piston for compressing the storage space of the first storage chamber, and the atomizing body has a liquid guide tube for piercing the flexible seal and a pushing part for driving the piston to compress, when the user needs to use the electronic atomizing device for inhalation, the liquid reservoir and atomizing body can be combined into the second state electronic atomizing device. In the process of assembling the liquid reservoir and the atomizing body into the second state of the electronic atomizing device, the liquid guide tube punctures the flexible seal and connects to the first storage chamber of the liquid reservoir, allowing the atomized liquid in the first storage chamber to be introduced into the second storage chamber of the atomizing body through the liquid guide tube. At the same time, the pusher part abuts against the piston and drives the piston to compress the storage space of the first storage chamber, increasing the pressure in the first storage chamber. Under the action of this increased pressure, the atomized liquid in the first storage chamber will be introduced into the second storage chamber more quickly, and the atomized liquid already introduced into the second storage chamber will be guided towards the atomizing core more quickly, so that the atomizing core can reach a wet state more quickly, thereby shortening the user's waiting time.

[0033] Therefore, the technical solution provided in this application embodiment can not only avoid leakage problems of electronic atomizing devices during transportation, but also shorten the waiting time for users to use it, thereby improving the user experience. Attached Figure Description

[0058] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0060] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, top, bottom, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0061] Furthermore, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0062] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0063] Furthermore, if the terms "and / or," "and / or," or "and / or" appear throughout the text, their meaning includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Additionally, the specification of this application describes numerous technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, feature A+B+C is disclosed in one example, and feature A+B+D+E is disclosed in another example. Features C and D are equivalent technical means that serve the same purpose. Technically, only one of them needs to be used, and it is impossible to use them simultaneously. Feature E can be combined with feature C technically. Therefore, the solution A+B+C+D should not be considered as having been recorded because it is technically infeasible, while the solution A+B+C+E should be considered as having been recorded.

[0064] Please refer to Figure 1-5 One embodiment of this application provides an electronic atomizing device, which includes a liquid reservoir 1 and an atomizing body 2, wherein:

[0065] The reservoir 1 includes a first housing 11, a piston 12, and a flexible seal 13. The first housing 11 has a first storage chamber 110 for storing atomized liquid. The piston 12 is at least partially slidably fitted within the first housing 11. The piston 12 has a liquid guide hole 1210 for discharging the atomized liquid from the first storage chamber 110. The flexible seal 13 seals the liquid guide hole 1210. The piston 12 is configured to move from a first position to a second position relative to the first housing 11 to compress the storage space of the first storage chamber 110.

[0066] The atomizing body 2 includes a second housing 21, an atomizing core 22, and a pusher 23. The second housing 21 has an atomizing channel 250 and a second storage chamber 2330 for storing atomizing liquid. The atomizing core 22 is connected to the second storage chamber 2330 so that the subsequent atomizing core 22 can draw atomizing liquid from the second storage chamber 2330 for heating and atomization. Moreover, the atomizing core 22 is installed on the airflow path of the atomizing channel 250 so that the vapor generated by the subsequent atomizing core 22 can be carried away by the suction airflow formed in the atomizing channel 250 for the user to inhale. The pusher 23 includes a pusher part 231 and a liquid guide tube 232. The pusher part 231 is connected to the second housing 21 and the liquid guide tube 232 respectively. The first end of the liquid guide tube 232 (i.e., the lower end of the liquid guide tube 232) is connected to the second storage chamber 2330.

[0067] The electronic atomizing device provided in this embodiment has a first state and a second state, wherein, as shown in the example... Figure 5 As shown, when the electronic atomizing device is in the first state, the second end (i.e., the upper end of the liquid guide tube 232) is sealed within the liquid guide hole 1210 and is positioned opposite to the flexible seal 13; please refer to the reference. Figure 5 and Figure 4 When the reservoir 1 is moved closer to the atomizing body 2 (i.e., the reservoir 1 is pushed downwards) to change the electronic atomizing device from the first state to the second state, the second end of the liquid guide tube 232 pierces the flexible seal 13 and connects to the first storage chamber 110. The pushing part 231 abuts against the piston 12 and drives the piston 12 from the first position to the second position. It should be noted that during the downward pushing of the reservoir 1, since the liquid guide tube 232 can maintain a sealed fit with the liquid guide hole 1210 of the piston 12 (specifically, the outer peripheral wall of the liquid guide tube 232 maintains elastic contact with the inner wall of the liquid guide hole 1210), after piercing the flexible seal 13, the atomized liquid in the first storage chamber 110 will not leak through the gap between the outer peripheral wall of the liquid guide tube 232 and the inner wall of the liquid guide hole 1210.

[0068] In this embodiment, it can be understood that, in specific implementation, the first storage chamber 110 of the liquid reservoir 1 may be pre-filled with atomizing liquid, while the second storage chamber 2330 of the atomizing body 2 may not be pre-filled with atomizing liquid.

[0069] In this embodiment, it should be noted that, in specific implementation, the flexible sealing element 13 can be a silicone film, a rubber film, or an aluminum foil, as long as it meets the requirements. This embodiment does not impose specific limitations on the structural form of the flexible sealing element 13. Furthermore, in some optional embodiments, in order to make the second end of the liquid guide tube 232 more easily pierce the flexible sealing element 13, the second end of the liquid guide tube 232 can be configured as a pointed structure. For example, the end face of the second end of the liquid guide tube 232 can be configured as an inclined surface, thereby forming a pointed structure at the second end of the liquid guide tube 232.

[0070] In this embodiment, based on the above structural design, on the one hand, since the liquid guide hole 1210 of the liquid reservoir 1 is sealed by the flexible seal 13 and the second storage cavity 2330 of the atomizing body 2 does not contain atomizing liquid before the liquid reservoir 1 and the atomizing body 2 are combined into the second state of the electronic atomizing device, when transporting the electronic atomizing device, whether the liquid reservoir 1 and the atomizing body 2 are transported separately or after the liquid reservoir 1 and the atomizing body 2 are combined into the first state of the electronic atomizing device, there will be no leakage problem between the liquid reservoir 1 and the atomizing body 2; on the other hand, when the user needs to use the electronic atomizing device for inhalation, the liquid reservoir 1 and the atomizing body 2 can be combined into the second state of the electronic atomizing device. During the process of combining the liquid reservoir 1 and the atomizing body 2 into the second state of the electronic atomizing device, the liquid guide tube 232 will pierce the flexible seal 13 and separate from the first storage cavity 2330 of the liquid reservoir 1. The cavities 110 are connected, allowing the atomizing liquid in the first storage cavity 110 to be introduced into the second storage cavity 2330 of the atomizing body 2 through the liquid guide tube 232. At the same time, the pusher 231 abuts against the piston 12 and drives the piston 12 from the initial first position to the predetermined second position, causing the storage space of the first storage cavity 110 to shrink due to compression by the piston 12, thereby increasing the pressure in the first storage cavity 110. Under the action of this increased pressure, the atomizing liquid in the first storage cavity 110 will be introduced into the second storage cavity 2330 more quickly. Moreover, after the atomizing liquid is introduced into the second storage cavity 2330, it will compress the air in the second storage cavity 2330, thereby increasing the air pressure in the second storage cavity 2330. Under the action of this increased air pressure, the atomizing liquid will be guided towards the atomizing core 22 more quickly, thereby enabling the atomizing core 22 to reach a wet state more quickly and shortening the user's waiting time.

[0071] Therefore, the technical solution provided in this embodiment can not only avoid leakage problems during the transportation of electronic atomizing devices, but also shorten the waiting time for users to use it, thereby improving the user experience.

[0072] Further, please refer to Figure 4 and Figure 5 In some optional embodiments of this application, assuming the volume of the second storage cavity 2330 is V2, and assuming the volume of the first storage cavity 110 decreases by V1 when the piston 12 moves from the first position to the second position, V1 can be set to 0.5V2≤V1≤V2. For example, assuming V2=2ML, the size of V1 can be set to 1ML~2ML. This setting not only allows the atomizing core 22 to reach a wetted state more quickly, but also effectively reduces the risk of leakage of atomizing liquid from the connection between the atomizing core 22 and the second storage cavity 2330 due to excessive air pressure generated in the second storage cavity 2330 during the process of "pressing" the atomized liquid in the first storage cavity 110 into the second storage cavity 2330.

[0073] Further, please refer to Figure 3-5 and Figure 11 In some optional embodiments of this application, the vertical distance L between the first position and the second position is 1.5 to 3.5 mm, that is, the stroke of the piston 12 during upward compression is 1.5 to 3.5 mm. This setting makes it easier to control the size range of V1 between 0.5V2 and V2.

[0074] Further, please refer to Figure 4-5 as well as Figure 11-12 In some optional embodiments of this application, the inner peripheral wall of the first storage cavity 110 is provided with a limiting step surface 113, which faces the piston member 12. When the piston member 12 is in the second position, the piston member 12 abuts against the limiting step surface 113. This arrangement ensures that the piston member 12 can accurately reach the desired second position, allowing the user to clearly perceive that the electronic atomizing device is in the second state. Specifically, during the process of the user assembling the liquid reservoir 1 and the atomizing body 2 to form the electronic atomizing device in the second state, when the piston member 12 abuts against the limiting step surface 113, the user can clearly perceive that the liquid reservoir 1 and the atomizing body 2 can no longer continue to move relative to each other, and thus can confirm that the electronic atomizing device is in the second state.

[0075] Further, please refer to Figure 5In some optional embodiments of this application, when the piston 12 is in the first position, the volume of the first storage chamber 110 can be set to 2 to 6 times the volume of the second storage chamber 2330. For example, assuming the volume of the second storage chamber 2330 of the atomizing body 2 is 2 ml (that is, it can hold 2 ml of atomizing liquid), then when the piston 12 is in the first position, the volume of the first storage chamber 110 of the reservoir 1 can be set to 4 ml to 12 ml, which is equivalent to indirectly increasing the atomizing liquid storage space of the atomizing body 2 by 2 to 6 times. This setting can not only effectively extend the usage time of the atomizing body 2, but also avoid the overall size of the electronic atomizing device being too large due to the excessive volume of the reservoir 1, thus affecting the user's portability.

[0076] Further, please refer to Figure 3-7 as well as Figure 11-12 In some optional embodiments of this application, the circumferential portion of the first housing 11 corresponding to the first storage cavity 110 is made of a transparent material. In specific implementations, the transparent material can be glass, acrylic, polycarbonate, etc., and the entire first housing 11 can be made of a transparent material. This arrangement allows the user to easily observe the remaining amount of atomizing liquid in the first storage cavity 110 of the liquid reservoir 1, enabling the user to intuitively know whether the atomizing liquid in the first storage cavity 110 has been completely consumed.

[0077] Furthermore, in some optional embodiments of this application, the specific structural composition of the liquid reservoir 1 may be as follows:

[0078] Specifically, please refer to Figure 3-12The reservoir 1 also includes a guide sleeve 14 made of a rigid material (such as metal or rigid plastic), which is at least partially fixed to the bottom end of the first housing 11, and the inner wall of the guide sleeve 14 is provided with at least one groove 140 extending along the height direction of the guide sleeve 14; the piston 12 includes a sealing plug 121 made of a flexible sealing material (such as silicone, rubber or silicone rubber) and a guide member 122 made of a rigid material (such as metal or rigid plastic). The sealing plug 121 has a mounting hole 1211 and a liquid guiding hole 1210. The outer peripheral wall of the sealing plug 121 is in elastic contact with the inner peripheral wall of the first housing 11. One end of the guide member 122 is fixedly connected to the sealing plug 121, and the other end is slidably engaged with the guide sleeve 14. The side wall of the guide member 122 is provided with at least one groove 140. The slide rail 1221 is adapted to each other, and each slide rail 1221 is slidably engaged with each slide groove 140 in a one-to-one correspondence; the first housing 11 is also provided with a mist outlet channel 1120, and the top of the first housing 11 is provided with a mouthpiece 111 that communicates with the mist outlet channel 1120. The first housing 11 is provided with an inner tube 112, which has at least a portion of the mist outlet channel 1120. The end of the inner tube 112 away from the mouthpiece 111 is inserted into the mounting hole 1211. The outer peripheral wall of the inner tube 112 is in elastic contact with the inner wall of the mounting hole 1211. The first housing 11, the inner tube 112 and the sealing plug 121 together define the first storage cavity 110. When the electronic atomizing device is in the second state, the mist outlet channel 1120 is connected to the atomization channel 250 and the first housing 11 is connected to the second housing 21.

[0079] In this embodiment, based on the above structural design, during the process of assembling the liquid reservoir 1 and the atomizing body 2 into the second state of the electronic atomizing device, on the one hand, the guiding effect between the slide rail 1221 and the slide groove 140 helps the pusher 231 to drive the entire piston 12 upward to compress more smoothly; on the other hand, since the sealing plug 121 can maintain a sealed fit with the first housing 11 and the inner tube 112 respectively during the upward compression of the piston 12, it can effectively prevent the atomized liquid in the first storage cavity 110 from leaking through the gap between the piston 12 and the inner wall of the first storage cavity 110.

[0080] In this embodiment, it should be noted that, in specific implementation, when the electronic atomizing device is in the second state, the connection between the first housing 11 and the second housing 21 can be a detachable connection (such as a magnetic connection, plug-in connection, or snap-fit ​​connection) or a non-detachable connection (such as a snap-fit ​​connection), depending on actual usage needs. This embodiment does not impose specific limitations on this. Preferably, when the electronic atomizing device is in the second state, the first housing 11 and the second housing 21 are detachably connected. With this configuration, after the atomizing liquid in the first storage chamber 110 and the second storage chamber 2330 is consumed, the user only needs to replace the new liquid reservoir 1 to continue using it, without having to replace the entire electronic atomizing device. That is, the atomizing body 2 can be reused, thereby helping to reduce the user's usage costs.

[0081] Furthermore, in some optional embodiments of this application, the structure of the atomizing body 2 can be as follows:

[0082] Specifically, please refer to Figure 4-5 In addition to 15-19, the pusher 23 also includes a cup portion 233 disposed within the second housing 21 (in some optional embodiments, the cup portion 233 and the second housing 21 can be fixed to each other by a snap-fit ​​connection). The pusher 231 is connected to the top of the cup portion 233. The atomizing body 2 also includes a base 24 located within the second housing 21 and an air duct 25 having at least a partial atomization channel 250. The base 24 can be made of silicone, rubber, or silicone rubber. The base 24 is sealed to the bottom end of the cup portion 233. One end of the air duct 25 is sealed to the pusher 231, and the other end is sealed to the base 24 (in some optional embodiments, the cup portion 233 and the second housing 21 can be fixed to each other by a snap-fit ​​connection). In the selected embodiment, the entire pusher 23 can be made of rigid plastic. The upper end of the airway tube 25 can be sealed to the pusher 231 through a flexible connecting sleeve 210, and the lower end of the airway tube 25 is tightly fitted to the base 24. The cup body 233, the pusher 231, the airway tube 25 and the base 24 together define the second storage cavity 2330. The side wall of the airway tube 25 is provided with at least one liquid inlet hole 251 that communicates with the second storage cavity 2330. The atomizing core 22 is installed in the airway tube 25, and the outer wall of the atomizing core 22 covers each liquid inlet hole 251 (that is, the atomizing core 22 is connected to the second storage cavity 2330 through each liquid inlet hole 251).

[0083] In this embodiment, based on the above structural design, the atomizing body 2 provided in this embodiment has the advantage of easy assembly. Specifically, during assembly, the atomizing core 22 can be installed in the airway tube 25 first, then the connecting sleeve 210 can be inserted into the lower side of the push part 231, then the lower end of the airway tube 25 can be inserted into the base 24, and then the upper end of the airway tube 25 can be inserted into the connecting sleeve 210 so that the base 24 and the lower end of the cup part 233 are tightly fitted, thereby obtaining a modular structure with the atomizing core 22. Finally, the modular structure can be installed into the second shell 21 for fixation. The whole assembly process is relatively convenient to operate.

[0084] Further, please refer to Figure 3 and Figure 13-14 In some optional embodiments of this application, the atomizing body 2 further includes a third housing 27, a battery 28, and a control circuit board 29. The third housing 27 is connected to the second housing 21. The battery 28 and the control circuit board 29 are both installed inside the third housing 27. The control circuit board 29 is electrically connected to the battery 28 and the atomizing core 22, respectively. In some specific application scenarios, users can trigger the control circuit board 29 to connect the battery 28 and the atomizing core 22 by pressing (in specific implementation, a switch button electrically connected to the control circuit board 29 can be set on the third housing 27) or by sucking (in specific implementation, an airflow sensor electrically connected to the control circuit board 29 can be set in the second housing 21 or the third housing 27, and the airflow sensor is used to detect changes in airflow along the path that connects the atomizing channel 250, the mist outlet channel 1120, and the mouthpiece 111 in sequence), so that the atomizing core 22 can be powered on to perform atomization and produce vapor that can be inhaled by the user. When the user bites the mouthpiece 111 to suck, the vapor produced by the atomizing core 22 can be expelled into the user's mouth and inhaled by the user.

[0085] In this embodiment, it should be noted that, in specific implementation, the connection between the third housing 27 and the second housing 21 can be a detachable connection (such as a magnetic connection, threaded connection, snap-fit ​​connection, plug-in connection, etc.) or a non-detachable connection (such as ultrasonic welding, hot melt adhesive bonding, etc.), which can be determined according to actual usage needs, and this embodiment does not impose specific limitations on this. In some optional embodiments, the sidewall of the third housing 27 is magnetically connected to the sidewall of the first housing 11 and the sidewall of the second housing 21, respectively.

[0086] Furthermore, considering that when the piston 12 is in the second position and the atomizing core 22 is wetted, the hydraulic pressure generated by the gravity of the atomizing liquid in the first storage chamber 110 still causes the atomizing liquid in the second storage chamber 2330 to flow towards the atomizing core 22 at a relatively fast rate, making it easy for the atomizing liquid to leak out of the atomizing core 22 and causing leakage problems. Based on this consideration, in order to reduce the risk of leakage in the electronic atomizing device in the second state, the atomizing body 2 can be optimized as follows:

[0087] Specifically, please refer to Figure 3-5 , Figure 14 as well as Figure 17-19 In some optional embodiments of this application, the atomizing body 2 further includes a storage liquid 26 made of a porous material (such as fiber cotton, sponge, porous glass, porous ceramic, etc.). The storage liquid 26 is disposed in the second storage cavity 2330. The storage liquid 26 is used to absorb the atomizing liquid in the second storage cavity 2330 and to transfer the atomizing liquid to the atomizing core 22 (in some optional embodiments, the storage liquid 26 may be in contact with the atomizing core 22). The first end port of the liquid guide tube 232 (i.e. the lower end port of the liquid guide tube 232) is spaced apart from the wall of the storage liquid 26.

[0088] In this embodiment, based on the above structural design, on the one hand, during the upward compression movement of the piston 12, the atomizing liquid in the first storage chamber 110 is absorbed by the storage liquid 26 after being introduced into the second storage chamber 2330. The atomizing liquid absorbed by the storage liquid 26 can be transferred to the atomizing core 22 through capillary action. As the atomizing liquid in the first storage chamber 110 is continuously introduced into the second storage chamber 2330, the air pressure in the second storage chamber 2330 will gradually increase. Under the action of air pressure, the atomizing liquid in the storage liquid 26 will be guided to the atomizing core 22 more quickly, thereby making... The atomizing core 22 can reach a wetted state more quickly. On the other hand, when the piston 12 is in the second position and the atomizing core 22 is wetted, the liquid storage 26 can absorb the atomized liquid in the second storage cavity 2330, thereby reducing the fluidity of the atomized liquid in the second storage cavity 2330. This slows down the speed at which the atomized liquid in the second storage cavity 2330 is guided to the atomizing core 22, thus reducing the risk of leakage in the electronic atomizing device in the second state due to the excessive speed at which the atomized liquid in the second storage cavity 2330 is guided to the atomizing core 22. In this embodiment, it should be noted that by setting the lower end of the liquid guide tube 232 at a distance from the wall of the liquid storage 26, it can be ensured that the atomized liquid in the first storage can be smoothly introduced into the second storage cavity 2330 and absorbed by the liquid storage 26, avoiding the lower end of the liquid guide tube 232 being blocked by the liquid storage 26, which would prevent the atomized liquid in the first storage cavity 110 from being difficult to smoothly introduced into the second storage cavity 2330.

[0089] Further, please refer to Figure 3 , Figure 14 , Figure 17 as well as Figures 19-20 In some optional embodiments of this application, a gap exists between the outer wall of the liquid storage 26 and the cavity wall of the second storage cavity 2330 to form an exhaust channel 261. The inner wall of the pusher 23 is provided with a venting groove 2310 located above the liquid storage 26. One end of the venting groove 2310 is connected to the exhaust channel 261 and the other end is connected to the atomization channel 250. The side wall of the liquid storage 26 is provided with a through groove 260 extending along the height direction of the liquid storage 26. One end of the through groove 260 penetrates the top surface of the liquid storage 26 and the other end penetrates the bottom surface of the liquid storage 26. The first end of the liquid guide tube 232 extends into the through groove 260, and the first end face of the liquid guide tube 232, the inner wall of the through groove 260, and the cavity wall of the second storage cavity 2330 together define a sealed space 2601.

[0090] In this embodiment, based on the above structural design, during the upward compression movement of the piston 12, after the atomizing liquid in the first storage chamber 110 is introduced into the sealed space 2601 through the liquid guide tube 232, the air pressure in the sealed space 2601 will increase. Under the squeezing action of the air pressure, the atomizing liquid in the sealed space 2601 will be introduced into the storage liquid 26 more quickly. After the atomizing liquid is introduced into the internal pores of the storage liquid 26, it will squeeze the air remaining in the internal pores of the storage liquid 26, so that the air remaining in the storage liquid 26 will be squeezed out into the exhaust channel 261 and finally discharged into the atomizing channel 250 through the ventilation groove 2310. After the air remaining in the storage liquid 26 is discharged from the storage liquid 26, the storage liquid 26 can more smoothly guide the atomizing liquid it has adsorbed to the atomizing core 22, thereby helping to further shorten the time required for the atomizing core 22 to reach a wet state. Furthermore, since the venting groove 2310 is located above the liquid storage 26 and the atomizing liquid in the second storage chamber 2330 is absorbed by the liquid storage 26, the atomizing liquid in the second storage chamber 2330 is unlikely to leak into the atomization channel 250 through the venting groove 2310.

[0091] In this embodiment, it should be noted that, in some specific application scenarios, in order to reduce the risk that the atomized liquid in the storage liquid 26 may leak out of the second storage chamber 2330 and into the atomization channel 250 through the venting groove 2310 due to the electronic atomizing device being inverted and subjected to vibration, the venting groove 2310 can be arranged in a roundabout manner, and / or the cross-sectional area of ​​the venting groove 2310 can be set to be smaller, for example, the cross-sectional area of ​​the venting groove 2310 can be set to 0.008mm. 2 ~0.15mm 2 .

[0092] In this embodiment, it should also be noted that the exhaust passage 261 can be formed in various ways during specific implementation, for example, as... Figure 17 and Figure 19 As shown, in some optional embodiments, the outer wall of the liquid storage 26 is provided with at least one first groove extending along the height direction of the liquid storage 26, which is the exhaust channel 261. For example, in other optional embodiments, the inner wall of the second storage cavity 2330 is provided with a second groove extending along the height direction of the pusher 23, which is the exhaust channel 261. Furthermore, in yet another optional embodiment, a portion of the outer wall surface of the liquid storage 26 (such as the outer wall and bottom surface of the liquid storage 26) contacts the inner wall of the second storage cavity 2330, while another portion of the outer wall surface of the liquid storage 26 (such as the top surface of the liquid storage 26; it can be understood that the outer wall of the liquid storage 26 is located between the top and bottom surfaces of the liquid storage 26) has a gap with the top wall of the second storage cavity 2330, thus forming the exhaust channel 261. This embodiment does not impose specific limitations on the specific formation method of the exhaust channel 261.

[0093] Furthermore, in some optional embodiments of this application, the number of liquid guiding tubes 232, the number of liquid guiding holes 1210, and the number of flexible seals 13 can all be set to two, and each liquid guiding tube 232, each liquid guiding hole 1210, and each flexible seal 13 is arranged in a one-to-one correspondence, as detailed below:

[0094] Please refer to Figure 4-5 , Figure 8-9 , Figure 12-13 and Figure 18-19 The flexible seal 13 includes a first sealing portion 131 and a second sealing portion 132. The liquid guiding hole 1210 includes a first hole portion 12101 and a second hole portion 12102 spaced apart. The liquid guiding tube 232 includes a first pipe portion 2321 and a second pipe portion 2322 spaced apart. The first sealing portion 131 seals the first hole portion 12101, and the second sealing portion 132 seals the second hole portion 12102. The first end of the first pipe portion 2321 and the first end of the second pipe portion 2322 are both connected to the second storage cavity 2330. When the electronic atomizing device is in use... In the first state, the second end of the first pipe section 2321 is sealed and fitted inside the first hole section 12101 and is disposed opposite to the first sealing section 131, and the second end of the second pipe section 2322 is sealed and fitted inside the second hole section 12102 and is disposed opposite to the second sealing section 132; when the electronic atomizing device is changed from the first state to the second state, the second end of the first pipe section 2321 pierces the first sealing section 131 and connects to the first storage cavity 110, and the second end of the second pipe section 2322 pierces the second sealing section 132 and connects to the first storage cavity 110.

[0095] In this embodiment, based on the above structural design, during the upward compression movement of the piston 12, the atomized liquid in the first storage chamber 110 can be simultaneously introduced into the second storage chamber 2330 through the first pipe section 2321 and the second pipe section 2322. Compared with setting the liquid guide pipe 232 as one, it is beneficial to further shorten the time required for the atomizing core 22 to reach a wet state.

[0096] In this embodiment, it should be noted that during subsequent use of the electronic atomizing device in the second state by the user, the atomized liquid in the second storage chamber 2330 (or liquid storage 26) will decrease due to consumption by the atomizing core 22. At the same time, the atomized liquid in the first storage chamber 110 will be introduced into the second storage chamber 2330 through the liquid guide tube 232 to replenish it under its own gravity. When the atomized liquid in the first storage chamber 110 decreases to a certain extent, the first storage chamber 110 will form a negative pressure due to the decrease in atomized liquid (at this time, the air pressure in the first storage chamber 110 is less than the atmospheric pressure). The existence of this negative pressure will prevent the atomized liquid in the first storage chamber 110 from continuing to be introduced into the second storage chamber 2330. To eliminate the negative pressure formed in the first storage chamber 110 so that the atomized liquid in the first storage chamber 110 can continue to be introduced into the second storage chamber 2330, air needs to enter the first storage chamber 110 through a return air process. Specifically, air from the external environment can enter the second storage chamber 2330 through the liquid inlet 251 of the atomization channel 250 and the air inlet 251 of the air passage 25 (in some specific application scenarios, the air in the atomization channel 250 can also enter the second storage chamber 2330 through the ventilation groove 2310). The air in the second storage chamber 2330 then flows back into the first storage chamber 110 through the liquid guide tube 232.

[0097] However, in some specific application scenarios, the applicant's research found that if the height of the first pipe section 2321 is set to be equal to the height of the second pipe section 2322 and the inner diameter of the first pipe section 2321 is set to be equal to the inner diameter of the second pipe section 2322, the atomizing liquid in the first storage chamber 110 will not be able to be continuously and stably introduced into the second storage chamber 2330. Specifically, during the user's vaping process, the atomizing liquid in the first storage chamber 110 will temporarily stop flowing into the second storage chamber 2330 or the flow rate into the second storage chamber 2330 will slow down. This can easily lead to insufficient atomizing liquid in the second storage chamber 2330 (or the liquid storage 26) and the inability to supply liquid to the atomizing core 22 in time, thereby increasing the risk of the atomizing core 22 running dry due to lack of liquid. The reason for this is that when the height of the first pipe section 2321 is equal to the height of the second pipe section 2322 and the inner diameter of the first pipe section 2321 is equal to the inner diameter of the second pipe section 2322, the flow velocity of the atomizing liquid in the first pipe section 2321 will be equal to the flow velocity of the atomizing liquid in the second pipe section 2322. Both the first pipe section 2321 and the second pipe section 2322 will be filled with atomizing liquid. Therefore, during the return air process, the resistance encountered by the air in the second storage cavity 2330 when passing through the first pipe section 2321 will be equal to the resistance encountered when passing through the second pipe section 2322. This causes the air in the second storage cavity 2330 to tend to flow back into the first storage cavity 110 while simultaneously passing through the first pipe section 2321 and the second pipe section 2322. However, due to the first pipe... Both section 2321 and the second pipe section 2322 are filled with atomizing liquid and both have the inertia of the atomizing liquid flowing downwards. Therefore, it is difficult for the air in the second storage chamber 2330 to flow back into the first storage chamber 110 through the first pipe section 2321 and the second pipe section 2322 at the same time. That is, both the first pipe section 2321 and the second pipe section 2322 will experience a relatively serious phenomenon of "liquid and air competing against each other in opposite directions" (i.e., the inertia of the atomizing liquid flowing downwards will hinder the air flowing upwards, and the air flowing upwards will hinder the atomizing liquid flowing downwards). This will lead to low air return efficiency, and the negative pressure formed in the first storage chamber 110 cannot be eliminated quickly. As a result, the atomizing liquid in the first storage chamber 110 cannot be continuously and stably introduced into the second storage chamber 2330.

[0098] Based on the above findings, in order to ensure that the atomizing liquid in the first storage chamber 110 can be continuously and stably introduced into the second storage chamber 2330 during the user's inhalation process, thereby reducing the risk of dry burning due to lack of liquid in the atomizing core 22, in some optional embodiments of this application, the liquid flow resistance of the first pipe section 2321 can be set to be greater than the liquid flow resistance of the second pipe section 2322. That is, the flow resistance of the atomizing liquid in the first pipe section 2321 is greater than the flow resistance of the atomizing liquid in the second pipe section 2322, so that the flow velocity of the atomizing liquid in the first pipe section 2321 is less than the flow velocity of the atomizing liquid in the second pipe section 2322. In specific implementations, to ensure that the flow rate of the atomized liquid in the first pipe section 2321 is less than the flow rate of the atomized liquid in the second pipe section 2322 after the liquid reservoir 1 and the atomizing body 2 are combined into the second state of the electronic atomizing device, in some optional embodiments, the height of the first pipe section 2321 can be set to be equal to the height of the second pipe section 2322, while the inner diameter of the first pipe section 2321 can be set to be smaller than the inner diameter of the second pipe section 2322; in other optional embodiments, the height of the first pipe section 2321 can be set to be greater than the height of the second pipe section 2322, while the inner diameter of the first pipe section 2321 can be set to be equal to the inner diameter of the second pipe section 2322; in still other optional embodiments, the height of the first pipe section 2321 can be set to be greater than the height of the second pipe section 2322, while the inner diameter of the first pipe section 2321 can be set to be smaller than the inner diameter of the second pipe section 2322.

[0099] In this embodiment, because the liquid flow resistance of the first pipe section 2321 is greater than that of the second pipe section 2322, most of the atomizing liquid in the first storage chamber 110 tends to be introduced into the second storage chamber 2330 through the second pipe section 2322 at a faster flow rate, thus filling the second pipe section 2322 with atomizing liquid. Simultaneously, a small portion of the atomizing liquid in the first storage chamber 110 is introduced into the second storage chamber 2330 through the first pipe section 2321 at a slower flow rate, resulting in insufficient liquid filling or gaps in the first pipe section 2321. Consequently, during the air return process, the air in the second storage chamber 2330 passes through the first pipe section 2322... The resistance encountered when passing through the first pipe section 2322 is less than that encountered when passing through the second pipe section 2322. This allows most of the air in the second storage chamber 2330 to preferentially flow back into the first storage chamber 110 through the first pipe section 2321 in the form of continuous airflow or bubble flow. This is equivalent to reducing the degree of "competition between liquid and air in the first pipe section 2321". Therefore, it can improve the efficiency and stability of air return, and the negative pressure formed in the first storage chamber 110 can be eliminated more quickly. This allows the atomizing liquid in the first storage chamber 110 to be continuously and stably introduced into the second storage chamber 2330 for replenishment, which in turn helps to reduce the risk of dry burning of the atomizing core 22 due to lack of liquid.

[0100] In this embodiment, it can be understood that by setting the liquid flow resistance of the first pipe section 2321 to be greater than the liquid flow resistance of the second pipe section 2322, it is equivalent to achieving the effect that "the first pipe section 2321 is mainly used for gas return and the second pipe section 2322 is mainly used for liquid discharge".

[0101] Further, please refer to Figure 4 , Figure 15 and Figure 18In some optional embodiments of this application, the second end face of the first pipe section 2321 includes a first inclined surface 23211, a first longitudinal surface 23212, and a first stepped surface 23213. The first inclined surface 23211 is connected to the first stepped surface 23213 through the first longitudinal surface 23212. The first longitudinal surface 23212 divides the second end face of the first pipe section 2321 in two. The included angle between the first longitudinal surface 23212 and the first stepped surface 23213 is 80° to 100° (exemplarily, the first longitudinal surface 23212 and the first stepped surface 23213 are arranged perpendicular to each other). Along the axial direction of the first pipe section 2321, the first inclined surface 23211 is higher than the first stepped surface 23213; the second end face of the second pipe section 2322... The surface includes a second inclined surface 23221, a second longitudinal surface 23222, and a second stepped surface 23223. The second inclined surface 23221 is connected to the second stepped surface 23223 via the second longitudinal surface 23222. The second longitudinal surface 23222 divides the second end port of the second pipe section 2322 in two. The included angle between the second longitudinal surface 23222 and the second stepped surface 23223 is 80° to 100° (exemplarily, the second longitudinal surface 23222 and the second stepped surface 23223 are arranged perpendicular to each other). Along the axial direction of the second pipe section 2322, the second inclined surface 23221 is higher than the second stepped surface 23223. Along the height direction of the pusher 23, the first stepped surface 23213 is higher than the second stepped surface 23223. For example, as shown in the figure... Figure 18 As shown, assuming the vertical height between the first step surface 23213 and the upper end surface of the push part 231 is H1, and the vertical height between the second step surface 23223 and the upper end surface of the push part 231 is H2, then H1 > H2. In specific implementation, the difference between H1 and H2 can be set to 1 to 5 mm.

[0102] In this embodiment, based on the above structural design, in the first aspect, the arrangement of the first inclined surface 23211 enables the upper end of the first pipe portion 2321 to form a pointed structure that facilitates piercing the first sealing portion 131. Similarly, the arrangement of the second inclined surface 23221 enables the upper end of the second pipe portion 2322 to form a pointed structure that facilitates piercing the second sealing portion 132. Secondly, by dividing the upper end of the first pipe section 2321 into two parts with a height difference, the atomizing liquid is less likely to form a liquid surface tension at the upper end of the first pipe section 2321, thereby avoiding the atomizing liquid forming a liquid surface tension at the upper end of the first pipe section 2321 and reducing the air return performance of the first pipe section 2321. Similarly, by dividing the upper end of the second pipe section 2322 into two parts with a height difference, the atomizing liquid is less likely to form a liquid surface tension at the upper end of the second pipe section 2322, thereby avoiding the atomizing liquid forming a liquid surface tension at the upper end of the second pipe section 2322 and reducing the liquid guiding performance of the second pipe section 2322. Thirdly, by setting the height of the first step surface 23213 to be higher than the height of the second step surface 23223, it is easier to make the liquid flow resistance of the first pipe section 2321 greater than the liquid flow resistance of the second pipe section 2322.

[0103] Further, please refer to Figure 4 In some optional embodiments of this application, the second end port of the second conduit portion 2322 is at least partially located within the second hole portion 12102. This arrangement ensures that the atomizing liquid in the first storage chamber 110 can ultimately be completely introduced into the second storage chamber 2330, thereby improving the utilization rate of the atomizing liquid in the first storage chamber 110 and avoiding waste of the atomizing liquid.

[0104] Further, please refer to Figure 4 and Figure 18In some optional embodiments of this application, the inner diameter of the first pipe portion 2321 is 0.6 to 1 mm, and the inner diameter of the second pipe portion 2322 is 1.2 to 2 mm. For example, the inner diameter of the first pipe portion 2321 can be set to 0.6 mm, 0.65 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc., and the inner diameter of the second pipe portion 2322 can be set to 1.2 mm, 1.4 mm, 1.6 mm, 1.7 mm, 1.8 mm, 2 mm, etc. In this way, on the one hand, it facilitates making the liquid flow resistance of the first pipe section 2321 greater than that of the second pipe section 2322. On the other hand, during the user's use of the electronic atomizing device in the second state for inhalation, not only can the air in the second storage chamber 2330 enter the first storage chamber 110 through the first pipe section 2321 at a more suitable flow rate, but the atomized liquid in the first storage chamber 110 can also be introduced into the second storage chamber 2330 through the second pipe section 2322 at a more suitable flow rate. This allows the atomized liquid in the first storage chamber 110 to be continuously and stably introduced into the second storage chamber 2330 for replenishment at a more suitable flow rate, avoiding the risk of leakage of the electronic atomizing device due to the atomized liquid being introduced into the second storage chamber 2330 too quickly, and avoiding the risk of dry burning of the atomizing core 22 due to insufficient liquid when the atomized liquid is introduced into the second storage chamber 2330 too slowly. In other words, it helps to improve the anti-leakage and anti-dry burning performance of the electronic atomizing device.
