[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 an atomization component and an electronic atomization device. Background Technology

[0004] An electronic atomizing device is an electronic device that can vaporize stored e-liquid, medicinal liquid, or other atomizing liquid into vapor mist through electric heating or other means. An electronic atomizing device typically includes a first storage chamber for storing the atomizing liquid and an atomizing core connected to the first storage chamber. The atomizing core is used to absorb the atomizing liquid in the first storage chamber and vaporize the atomizing liquid into vapor mist.

[0005] In related technologies, the volume of the first storage chamber of an electronic atomizing device is typically designed to be relatively small (usually 2 ml), making it impossible to pre-fill with a large amount of atomized liquid at the factory, thus resulting in a short continuous operating time. To improve the operating time of electronic atomizing devices, a reservoir can be added to replenish the atomized liquid in the first storage chamber. When the atomized liquid stored in the first storage chamber is consumed by the atomizer coil, the atomized liquid pre-filled in the second storage chamber can be replenished by gravity, thereby extending the operating time of the electronic atomizing device. However, the applicant's research has found that such electronic atomizing devices equipped with reservoirs generally suffer from the following problems:

[0006] There is usually only one liquid channel between the first and second storage chambers. This can easily lead to a problem where the atomizer coil runs dry and burns out because the atomized liquid in the second storage chamber cannot be replenished to the first storage chamber in time. The reason for this is that during vaping, the atomized liquid in the first storage chamber decreases due to consumption by the atomizer coil. Simultaneously, the atomized liquid in the second storage chamber, under its own gravity, flows through the liquid channel into the first storage chamber to replenish it. However, when the atomized liquid in the second storage chamber decreases to a certain level, a negative pressure (the air pressure inside the second storage chamber is lower than atmospheric pressure) forms. This negative pressure prevents the atomized liquid from the second storage chamber from continuing to flow into the first storage chamber. To eliminate the negative pressure in the second storage chamber and allow the atomized liquid to continue flowing into the first storage chamber, air needs to enter the second storage chamber through a return air process. Specifically, air from the outside environment enters the first storage chamber through the connection between the atomizing core and the first storage chamber. The air in the first storage chamber then flows counter-currently into the second storage chamber through the liquid guiding channel. Since the liquid supply path of the atomized liquid in the second storage chamber into the first storage chamber through the liquid guiding channel and the return air path of the air in the first storage chamber into the second storage chamber through the liquid guiding channel are completely overlapping, this is the same path. Furthermore, since the flow directions of the two are opposite, a severe "reverse flow competition between liquid and air" phenomenon will occur in the liquid guiding channel, resulting in low return air efficiency and poor stability. This makes it impossible to quickly eliminate the negative pressure formed in the second storage chamber of the liquid reservoir, which will cause the atomizing liquid in the second storage chamber to be introduced into the first storage chamber too slowly. This can easily lead to insufficient atomizing liquid in the first storage chamber, making it impossible to supply liquid to the atomizing core in time (especially when the atomizing core is continuously atomizing at a high power). This can lead to the problem of dry burning of the atomizing core due to lack of liquid.

Compared with the technical solution of setting only one liquid guide channel between the first storage chamber and the second storage chamber, the efficiency and stability of gas return can be improved, so that the negative pressure formed in the first storage chamber of the liquid reservoir can be eliminated more quickly. Thus, the atomized liquid in the first storage chamber of the liquid reservoir can be continuously and stably introduced into the second storage chamber of the atomizing body through the second liquid guide pipe for replenishment, thereby effectively reducing the risk of dry burning of the atomizing core due to lack of liquid.

[0052] 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

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] Please refer to Figure 1-11 One embodiment of this application provides an electronic atomizing device, which includes a liquid reservoir 1 and an atomizing body 2, wherein:

[0059] like Figure 3-9 As shown, the liquid reservoir 1 includes a first housing 11 and a sealing plug 12. The first housing 11 has a first storage chamber 110 for storing atomizing liquid. The sealing plug 12 is sealed and fitted inside the first housing 11 (specifically, the sealing plug 12 is sealed and fitted inside the bottom of the first housing 11). The sealing plug 12 has a first liquid guiding hole 121 and a second liquid guiding hole 122 that are spaced apart. In specific implementation, the material of the sealing plug 12 can be silicone, rubber or silicone rubber.

[0060] like Figure 3-5 as well as Figure 10-16As shown, the atomizing body 2 includes a second housing 25, an atomizing core 22, and a first liquid guide tube 23 and a second liquid guide tube 24 spaced apart. The second housing 25 has an atomizing channel 280 and a second storage chamber 250 for storing atomizing liquid. The atomizing core 22 is connected to the second storage chamber 250, allowing subsequent atomizing cores 22 to draw atomizing liquid from the second storage chamber 250 for heating and atomization. Furthermore, the atomizing core 22 is installed on the airflow path of the atomizing channel 280, so that the vapor generated by subsequent atomizing cores 22 can be carried away by the suction airflow formed in the atomizing channel 280 for user inhalation. The upper end of the first liquid guide tube 23 is connected to the top of the second housing 25, and a portion of the first liquid guide tube 23 is sealed to the first liquid guide hole 121. The upper end of a liquid guide tube 23 is connected to the first storage cavity 110, and the lower end of the first liquid guide tube 23 is connected to the second storage cavity 250. The upper end of the second liquid guide tube 24 is connected to the top of the second housing 25. A portion of the second liquid guide tube 24 is sealed to the second liquid guide hole 122. The upper end of the second liquid guide tube 24 is connected to the first storage cavity 110, and the lower end of the second liquid guide tube 24 is connected to the second storage cavity 250. The liquid flow resistance of the first liquid guide tube 23 is greater than that of the second liquid guide tube 24. That is, the flow resistance of the atomized liquid in the first liquid guide tube 23 is greater than that in the second liquid guide tube 24, so that the flow velocity of the atomized liquid in the first liquid guide tube 23 is less than that in the second liquid guide tube 24.

[0061] In this embodiment, it should be noted that, in specific implementations, to ensure that the liquid flow resistance of the first liquid guide tube 23 is greater than that of the second liquid guide tube 24, in some optional embodiments, the height of the first liquid guide tube 23 can be set to be equal to the height of the second liquid guide tube 24 (that is, along the height direction of the atomizing body 2, the height of the upper end of the first liquid guide tube 23 is equal to the height of the upper end of the second liquid guide tube 24), while the inner diameter of the first liquid guide tube 23 is set to be smaller than the inner diameter of the second liquid guide tube 24. In other optional embodiments, the height of the first liquid guide tube 23 can also be set to be greater than the height of the second liquid guide tube 24 (that is, along the height direction of the atomizing body 2, the height of the upper end of the first liquid guide tube 23 is greater than the height of the upper end of the second liquid guide tube 24), while the inner diameter of the first liquid guide tube 23 is set to be equal to the inner diameter of the second liquid guide tube 24. In some alternative embodiments, the height of the first liquid guide tube 23 may be set to be greater than the height of the second liquid guide tube 24, while the inner diameter of the first liquid guide tube 23 may be set to be smaller than the inner diameter of the second liquid guide tube 24. This is only necessary if the flow resistance of the atomized liquid in the first liquid guide tube 23 is greater than the flow resistance of the atomized liquid in the second liquid guide tube 24; this embodiment does not impose specific limitations on this.

[0062] In this embodiment, it should be further explained that, in some specific application scenarios, the applicant has found that, in addition to the problem of dry burning due to lack of liquid in the atomizing core 22 caused by using a single liquid guide tube to connect the first storage chamber 110 and the second storage chamber 250, the same problem of dry burning due to lack of liquid in the atomizing core 22 can also be caused by using two liquid guide tubes of the same specifications (i.e., the inner diameter and height of the two liquid guide tubes are the same). The reason for this is that when the specifications of the two liquid guide tubes are the same, the flow rate of the atomizing liquid in the two liquid guide tubes will be the same, and both liquid guide tubes will be filled with atomizing liquid. Therefore, during the air return process, the resistance encountered by the air in the second storage chamber 250 when passing through one of the liquid guide tubes will be equal to the resistance encountered when passing through the other liquid guide tube, resulting in the air in the second storage chamber 250 being unable to dry-burn due to lack of liquid. The air tends to flow back into the first storage chamber 110 of the reservoir 1 through both liquid guide tubes. However, since both liquid guide tubes are filled with atomizing liquid and both have the inertia of the atomizing liquid flowing downward, it is difficult for the air in the second storage chamber 250 to flow back into the first storage chamber 110 through both liquid guide tubes at the same time. That is, both liquid guide tubes of the same specification 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 downward will hinder the air flowing upward, and the air flowing upward will hinder the atomizing liquid flowing downward). This will result in low air return efficiency, and the negative pressure formed in the first storage chamber 110 cannot be eliminated quickly. As a result, the speed at which the atomizing liquid in the first storage chamber 110 flows into the second storage chamber 250 is too slow, making the atomizing core 22 prone to dry burning due to lack of liquid.

[0063] In the technical solution provided in this embodiment, since the liquid flow resistance of the first liquid guide tube 23 is greater than that of the second liquid guide tube 24, most of the atomizing liquid in the first storage cavity 110 tends to be introduced into the second storage cavity 250 at a faster flow rate through the second liquid guide tube 24, thus filling the second liquid guide tube 24 with atomizing liquid. Simultaneously, a small portion of the atomizing liquid in the first storage cavity 110 is introduced into the second storage cavity 250 at a slower flow rate through the first liquid guide tube 23, resulting in insufficient liquid filling or gaps in the first liquid guide tube 23. Consequently, during the air return process, the air in the second storage cavity 250 passes through the first liquid guide tube 23... The resistance encountered when passing through the first liquid guide tube 23 is less than that encountered when passing through the second liquid guide tube 24. This allows most of the air in the second storage chamber 250 to preferentially flow back into the first storage chamber 110 in the form of a continuous airflow or bubble flow through the first liquid guide tube 23. This reduces the degree of "competition between liquid and air flowing back and forth in the first liquid guide tube 23," thereby improving the efficiency and stability of air return. This allows the negative pressure formed in the first storage chamber 110 to be eliminated more quickly, enabling the atomizing liquid in the first storage chamber 110 to be continuously and stably introduced into the second storage chamber 250 for replenishment. This, in turn, helps reduce the risk of dry burning of the atomizing core 22 due to lack of liquid. It can be understood that in this embodiment, by setting the liquid flow resistance of the first liquid guide tube 23 to be greater than that of the second liquid guide tube 24, it is equivalent to achieving the effect that "the first liquid guide tube 23 is mainly used for air return, and the second liquid guide tube 24 is mainly used for liquid output."

[0064] In this embodiment, it is understood that in some specific application scenarios, the liquid reservoir 1 and the atomizing body 2 are two independent modules at the factory. During use, the user can combine the liquid reservoir 1 and the atomizing body 2 into a single unit to form a complete electronic atomizing device. In some optional embodiments, the first storage chamber 110 of the liquid reservoir 1 may be pre-filled with atomizing liquid at the factory, while the second storage chamber 250 of the atomizing body 2 may not be pre-filled with atomizing liquid. In other optional embodiments, both the first storage chamber 110 of the liquid reservoir 1 and the second storage chamber 250 of the atomizing body 2 may be pre-filled with atomizing liquid at the factory. Whether the second storage chamber 250 of the atomizing body 2 is pre-filled with atomizing liquid at the factory depends on the actual usage, and this embodiment does not impose specific limitations on this.

[0065] It is understood here that when the first storage chamber 110 of the reservoir 1 is pre-filled with atomizing liquid, in order to prevent the atomizing liquid in the first storage chamber 110 from leaking to the outside through the first liquid guide hole 121 and the second liquid guide hole 122 before the reservoir 1 and the atomizing body 2 are combined into one unit for use, and at the same time, in order to ensure that after the reservoir 1 and the atomizing body 2 are combined into one unit, the atomizing liquid in the first storage chamber 110 can be introduced into the second storage chamber 250 of the atomizing body 2 through the first liquid guide tube 23 and the second liquid guide tube 24, such as... Figure 9 As shown, the reservoir 1 typically also includes a first flexible seal 13 for sealing the first liquid guide hole 121 and a second flexible seal 14 for sealing the second liquid guide hole 122, such as... Figure 4 As shown, when the liquid reservoir 1 and the atomizing body 2 are combined into a single unit to form a complete electronic atomizing device, the upper end of the first liquid guide tube 23 will pierce the first flexible seal 13, and the upper end of the second liquid guide tube 24 will pierce the second flexible seal 14, thereby connecting the upper ports of both the first liquid guide tube 23 and the second liquid guide tube 24 to the first storage cavity 110. The structural form of the first flexible seal 13 and the second flexible seal 14 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 first flexible seal 13 and the second flexible seal 14.

[0066] It should be noted that, compared to the factory-pre-filled atomizing liquid in the second storage chamber 250 of the atomizing body 2, the advantage of not pre-filling the second storage chamber 250 of the atomizing body 2 is that, during the separate transportation of the atomizing body 2, the atomizing liquid will not leak from the atomizing core 22 due to factors such as changes in external air pressure, thus avoiding the problem of leakage before the atomizing body 2 is used. The disadvantage is that, after the liquid reservoir 1 and the atomizing body 2 are combined into one unit, in order to avoid the problem of the atomizing core 22 running dry due to lack of liquid, the user needs to wait until the liquid-free atomizing core 22 has absorbed the atomizing liquid in the second storage chamber 250 until it is moist before starting to use it. In other words, after the liquid reservoir 1 and the atomizing body 2 are combined into one unit, the user still needs to wait a relatively long time before starting to use it.

[0067] Further, please refer to Figure 4 and Figure 15In some optional embodiments of this application, the inner diameter of the first liquid guide tube 23 is 0.6-1 mm, and the inner diameter of the second liquid guide tube 24 is 1.2-2 mm. For example, the inner diameter of the first liquid guide tube 23 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 liquid guide tube 24 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 liquid guide tube 23 greater than that of the second liquid guide tube 24. On the other hand, during the user's use of the electronic atomizing device for inhalation, not only can the air in the second storage chamber 250 enter the first storage chamber 110 through the first liquid guide tube 23 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 250 through the second liquid guide tube 24 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 250 at a more suitable flow rate for replenishment. This avoids the risk of leakage of the electronic atomizing device due to the atomized liquid being introduced into the second storage chamber 250 too quickly, and also avoids 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 250 too slowly. In other words, it helps to improve the anti-leakage and anti-dry burning performance of the electronic atomizing device.

[0068] Further, please refer to Figure 4 In some optional embodiments of this application, the upper port of the second liquid guide tube 24 is at least partially located within the second liquid guide hole 122. This arrangement ensures that the atomizing liquid in the first storage cavity 110 can ultimately be completely introduced into the second storage cavity 250, thereby improving the utilization rate of the atomizing liquid in the first storage cavity 110 and avoiding waste of the atomizing liquid.

[0069] Further, please refer to Figure 3-4 In some optional embodiments of this application, the volume of the first storage chamber 110 is 2 to 5 times the volume of the second storage chamber 250. For example, assuming the volume of the second storage chamber 250 of the atomizing body 2 is 2 ml (that is, it can hold 2 ml of atomizing liquid), the volume of the first storage chamber 110 of the liquid reservoir 1 can be set to 4 ml to 10 ml, which is equivalent to indirectly increasing the atomizing liquid storage space of the atomizing body 2 by 2 to 5 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 excessively large volume of the liquid reservoir 1, thus affecting the user's portability.

[0070] Further, please refer to Figure 1 and Figure 3In 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.

[0071] Furthermore, in some optional embodiments of this application, the specific structural composition of the liquid reservoir 1 may be as follows:

[0072] Specifically, please refer to Figure 3-4 as well as Figure 6-9 The outer peripheral wall of the sealing plug 12 is in elastic contact with the inner peripheral wall of the first housing 11. The first housing 11 is also provided with a mist outlet channel 1120. The top of the first housing 11 is provided with a suction nozzle 111 that communicates with the mist outlet channel 1120. The sealing plug 12 also has a mounting hole 123. The mounting hole 123, the first liquid guide hole 121, and the second liquid guide hole 122 are arranged alternately. The first housing 11 is provided with an inner tube 112. The inner tube 112 has at least a portion of the mist outlet channel 1120. The lower end of the inner tube 112 is inserted into the mounting hole 123. The outer peripheral wall of the inner tube 112 is in elastic contact with the inner wall of the mounting hole 123. The first housing 11, the inner tube 112, and the sealing plug 12 together define the first storage cavity 110.

[0073] In this embodiment, based on the above structural design, the liquid reservoir 1 provided in this embodiment has the advantages of simple structure and convenient assembly. Moreover, since the sealing plug 12 can maintain a sealed fit with the first housing 11 and the inner tube 112 respectively, it can effectively prevent the atomized liquid in the first storage cavity 110 from leaking through the gap between the sealing plug 12 and the inner wall of the first storage cavity 110.

[0074] Furthermore, in some specific application scenarios, considering that after the atomizing core 22 reaches a wet state, 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 250 to flow towards the atomizing core 22 at a relatively fast rate, which may cause the atomizing liquid to leak out from the atomizing core 22, resulting in a leakage problem. Based on this consideration, in order to reduce the risk of leakage in the electronic atomizing device, the atomizing body 2 can be optimized as follows:

[0075] Specifically, please refer to Figure 3-4 , Figure 11 as well as Figure 14-16The atomizing body 2 also includes a liquid storage 26 made of porous materials (such as fiber cotton, sponge, porous glass, porous ceramics, etc.). The liquid storage 26 is disposed in the second storage cavity 250. The liquid storage 26 is used to adsorb the atomizing liquid in the second storage cavity 250 and can transfer the atomizing liquid adsorbed by itself to the atomizing core 22 through capillary action (in some optional embodiments, the liquid storage 26 can be in contact with the atomizing core 22). The lower port of the first liquid guide tube 23 and the lower port of the second liquid guide tube 24 are both spaced apart from the wall surface of the liquid storage 26.

[0076] In this embodiment, based on the above structural design, firstly, the liquid storage 26 can adsorb the atomizing liquid in the second storage cavity 250, thereby reducing the fluidity of the atomizing liquid in the second storage cavity 250, slowing down the speed at which the atomizing liquid in the second storage cavity 250 guides the atomizing core 22, and thus reducing the risk of leakage of the electronic atomizing device due to the atomizing liquid in the second storage cavity 250 guiding the atomizing core 22 too fast. Secondly, by setting the lower end of the first liquid guide tube 23 apart from the wall of the liquid storage 26, the lower end of the first liquid guide tube 23 can be prevented from being blocked by the liquid storage 26, thus affecting the efficiency of subsequent gas return. Thirdly, by setting the lower end of the second liquid guide tube 24 apart from the wall of the liquid storage 26, the atomized liquid in the first storage chamber 110 can be smoothly introduced into the second storage chamber 250 and absorbed by the liquid storage 26, thus preventing the lower end of the second liquid guide tube 24 from being blocked by the liquid storage 26, thus affecting the efficiency of introducing the atomized liquid in the first storage chamber 110 into the second storage chamber 250.

[0077] Further, please refer to Figure 3-4 , Figure 11 as well as Figure 14-17In some optional embodiments of this application, the inner wall of the second housing 25 is provided with a venting groove 2510 located above the liquid storage 26. A gap exists between the outer wall of the liquid storage 26 and the cavity wall of the second storage chamber 250, forming an exhaust channel 263. One end of the venting groove 2510 is connected to the exhaust channel 263, and the other end is connected to the atomization channel 280. The side wall of the liquid storage 26 is provided with a first through groove 261 and a second through groove 262 spaced apart. Both the first through groove 261 and the second through groove 262 extend along the height direction of the liquid storage 26. The upper end of the first through groove 261 and the second through groove 262 are connected together. The upper ends of the two through grooves 262 both penetrate the top surface of the liquid storage 26, and the lower ends of the first through groove 261 and the second through groove 262 both penetrate the bottom surface of the liquid storage 26. The lower end of the first liquid guide tube 23 extends into the first through groove 261, and the lower end face of the first liquid guide tube 23, the inner wall of the first through groove 261, and the cavity wall of the second storage cavity 250 together define the first sealed space 2611. The lower end of the second liquid guide tube 24 extends into the second through groove 262, and the lower end face of the second liquid guide tube 24, the inner wall of the second through groove 262, and the cavity wall of the second storage cavity 250 together define the second sealed space 2621.

[0078] In this embodiment, based on the above structural design, in some application scenarios where the second storage cavity 250 of the atomizing body 2 is not pre-filled with atomizing liquid, when the liquid reservoir 1 and the atomizing body 2 are combined into one unit, the atomizing liquid in the first storage cavity 110 will be simultaneously introduced into the first storage cavity 110 through the first liquid guide tube 23 and the second liquid guide tube 24 under its own gravity. (It can be understood that, since the liquid flow resistance of the first liquid guide tube 23 is greater than that of the second liquid guide tube 24, the flow velocity of the atomizing liquid in the first liquid guide tube 23 will be less than that of the second liquid guide tube 24.) (The flow rate of the atomizing liquid in the second liquid guide tube 24) When the atomizing liquid in the first storage chamber 110 is introduced into the first sealed space 2611 through the first liquid guide tube 23, the first air pressure in the first sealed space 2611 will increase. Under the squeezing action of the increased first air pressure, the atomizing liquid in the first sealed space 2611 will be introduced into the part of the storage liquid 26 located between the first sealed space 2611 and the atomizing core 22 (for ease of description, the part of the storage liquid 26 located between the first sealed space 2611 and the atomizing core 22 is defined as the first storage liquid). After the atomizing liquid is introduced into the internal pores of the first liquid storage section, it will compress the air remaining in the internal pores of the first liquid storage section, causing the air remaining in the first liquid storage section to be squeezed out into the exhaust channel 263 and finally discharged into the atomizing channel 280 through the venting groove 2510; at the same time, when the atomizing liquid in the first storage cavity 110 is introduced into the second sealed space 2621 through the second liquid guide tube 24, the second air pressure in the second sealed space 2621 will increase. Under the compression action of the increased second air pressure, the second sealed space The atomizing liquid in 2621 will be introduced into the part of the reservoir 26 located between the second sealed space 2621 and the atomizing core 22 at an accelerated rate (for ease of description, the part of the reservoir 26 located between the second sealed space 2621 and the atomizing core 22 is defined as the second reservoir). After the atomizing liquid is introduced into the internal pores of the second reservoir, it will compress the air remaining in the internal pores of the second reservoir, so that the air remaining in the second reservoir will be squeezed out into the exhaust channel 263 and finally discharged into the atomizing channel 280 through the ventilation groove 2510. After the air remaining in the first and second liquid storage sections is expelled from the liquid storage 26, the entire liquid storage 26 can absorb and store more atomizing liquid and more smoothly guide the absorbed atomizing liquid to the atomizing core 22. This not only helps to shorten the time required for the atomizing core 22 to reach a humid state, but also helps the liquid storage 26 to replenish the atomizing core 22 more promptly during subsequent use of the electronic atomizing device, thereby reducing the risk of the atomizing core 22 running dry due to lack of liquid.

[0079] In this embodiment, it is understood that when the atomized liquid in the first storage chamber 110 of the liquid reservoir 1 decreases to a certain extent and requires air return to eliminate the negative pressure formed in the first storage chamber 110, air from the external environment can be introduced into the first storage chamber 110 through the following two air return paths:

[0080] The first air return path is as follows: atomizing channel 280 → the position where the atomizing core 22 connects to the first storage chamber 110 → the internal pores of the liquid storage 26 → the first sealed space 2611 and the second sealed space 2621 → the first liquid guide tube 23 and the second liquid guide tube 24 → the first storage chamber 110. Since the air in the second storage chamber 250 experiences less resistance when passing through the first liquid guide tube 23 than when passing through the second liquid guide tube 24, the air in the first sealed space 2611 can be introduced into the first storage chamber 110 at a faster rate, while the air in the second sealed space 2621 is introduced into the first storage chamber 110 at a relatively slower rate.

[0081] The second return air path is: atomization channel 280 → ventilation slot 2510 → exhaust channel 263 → internal pores of liquid storage 26 → first sealed space 2611 and second sealed space 2621 → first liquid guide tube 23 and second liquid guide tube 24 → first storage chamber 110.

[0082] In this embodiment, it should be noted that since the venting groove 2510 is located above the liquid storage 26 and the atomized liquid in the second storage chamber 250 is absorbed by the liquid storage 26, the atomized liquid in the second storage chamber 250 is unlikely to leak into the atomization channel 280 through the venting groove 2510. It should also be noted that in some specific application scenarios, to reduce the risk of atomized liquid in the liquid storage 26 seeping into the exhaust channel 263 and then leaking into the atomization channel 280 through the venting groove 2510 due to the electronic atomizing device being inverted and subjected to vibration, the venting groove 2510 can be arranged in a roundabout manner, and / or its cross-sectional area can be made smaller, for example, the cross-sectional area of ​​the venting groove 2510 can be set to 0.008mm² to 0.15mm². 2 .

[0083] In this embodiment, it should also be noted that the exhaust channel 263 can be formed in various ways during specific implementation, for example, as... Figure 3 and Figure 16As 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 263. For example, in other optional embodiments, the inner wall of the second storage cavity 250 is provided with a second groove extending along the height direction of the second housing 25, which is the exhaust channel 263. 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 250, 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 250, thus forming the exhaust channel 263. This embodiment does not impose specific limitations on the specific formation method of the exhaust channel 263.

[0084] Furthermore, in some optional embodiments of this application, the structure of the atomizing body 2 can be as follows:

[0085] Specifically, please refer to Figure 10-17 The second housing 25 includes a cup body 252 and a top cover 251 having a first connecting through hole 2511. The atomizing body 2 also includes a base 27 having a second connecting through hole 270 and an air duct 28 having at least a partial atomizing channel 280. The top cover 251 is integrally connected to the top of the cup body 252, and the inner wall of the top cover 251 is provided with an air vent 2510. The base 27 is sealed to the bottom of the cup body 252. The upper end of the air duct 28 can be sealed and connected to the first connecting through hole 2511 of the top cover 251 through a flexible connecting sleeve 210. The lower end of the air duct 28 is sealed and fitted in the second connecting through hole 270 of the base 27. The cup body 252, the top cover 251, the air duct 28, and the base are all connected together. 27 together define the second storage cavity 250. The side wall of the air passage tube 28 is provided with at least one liquid inlet hole 281 that communicates with the second storage cavity 250. The atomizing core 22 is installed in the air passage tube 28 and the outer wall of the atomizing core 22 covers each liquid inlet hole 281 (that is, the atomizing core 22 is connected to the second storage cavity 250 through each liquid inlet hole 281). The upper end of the first liquid guide tube 23 and the upper end of the second liquid guide tube 24 are integrally connected to the upper side of the top cover 251 (in some optional embodiments, the first liquid guide tube 23, the second liquid guide tube 24 and the entire second housing 25 can all be made of rigid plastic, and the first liquid guide tube 23, the second liquid guide tube 24 and the second housing 25 can be integrally formed by injection molding).

[0086] 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 28 first, then the upper end of the connecting sleeve 210 can be inserted into the first connecting through hole 2511 of the push part, then the lower end of the airway tube 28 can be inserted into the second connecting through hole 270 of the base 27, and then the upper end of the airway tube 28 can be inserted into the connecting sleeve 210 so that the base 27 and the lower end of the cup body 252 are tightly fitted. In this way, the assembly of the atomizing body 2 can be completed. The whole assembly process is relatively convenient to operate.

[0087] Further, please refer to Figure 3-4 as well as Figure 10-17 In some optional embodiments of this application, the atomizing body 2 may further include a shell 21, with the second shell 25 and the base 27 both located within the shell 21, and the shell 21 connected to the first shell 11 and the second shell 25 respectively. In this embodiment, the shell 21 improves the impact resistance of the atomizing body 2. Specifically, the connection between the first shell 11 and the shell 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, the first shell 11 and the shell 21 are detachably connected. With this configuration, once the atomizing liquid in the first storage chamber 110 and the second storage chamber 250 is consumed, the user only needs to replace the new liquid reservoir 1 to continue using the device, without needing to replace the entire electronic atomizing device. This means the atomizing body 2 can be reused, thereby reducing user costs. Furthermore, in specific implementations, the cup body portion 252 of the second housing 25 and the outer housing 21 can be fixed to each other by means of a snap-fit ​​connection.

[0088] Further, please refer to Figure 3 , Figure 5 as well as Figure 10-11In some optional embodiments of this application, the atomizing body 2 further includes a third housing 293, a battery 291, and a control circuit board 292. The third housing 293 is connected to the second housing 25 (specifically, the third housing 293 is indirectly connected to the second housing 25 through the outer shell 21). The battery 291 and the control circuit board 292 are both installed inside the third housing 293. The control circuit board 292 is electrically connected to the battery 291 and the atomizing core 22, respectively. In some specific application scenarios, users can trigger the control circuit board 292 to connect the battery 291 and the atomizing core 22 by pressing (in specific implementation, a switch button electrically connected to the control circuit board 292 can be set on the third housing 293) or by sucking (in specific implementation, an airflow sensor electrically connected to the control circuit board 292 can be set in the outer housing 21 or the third housing 293, and the airflow sensor is used to detect the airflow changes on the path that the atomizing channel 280, the mist outlet channel 1120, and the mouthpiece 111 are connected in sequence). This allows the atomizing core 22 to be powered on to perform atomization and produce vapor that can be inhaled by the user. When the user bites the mouthpiece 111 and sucks, the vapor produced by the atomizing core 22 can be discharged into the user's mouth and inhaled by the user.

[0089] In this embodiment, it should be noted that, in specific implementation, the connection between the third housing 293 and the outer 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 293 is magnetically connected to the sidewall of the first housing 11 and the sidewall of the outer housing 21, respectively.

[0090] Furthermore, please refer to the following: Figure 4-5 , Figure 9-10 , Figure 12 and Figure 15 In some optional embodiments of this application, in order to make it easier for the upper end of the first liquid guide tube 23 to pierce the first flexible seal 13 and the upper end of the second liquid guide tube 24 to pierce the second flexible seal 14 when the liquid reservoir 1 and the atomizing body 2 are combined into one unit, the upper ends of the first liquid guide tube 23 and the upper ends of the second liquid guide tube 24 can both be set as pointed structures. For example, the upper end face of the first liquid guide tube 23 and the upper end face of the second liquid guide tube 24 can both be set as inclined surfaces, so that the upper ends of the first liquid guide tube 23 and the upper ends of the second liquid guide tube 24 are both formed as pointed structures.

[0091] Further, please refer to Figure 12 and Figure 15In some optional embodiments of this application, the upper end face of the first liquid guide tube 23 includes a first inclined surface 231, a first longitudinal surface 232, and a first stepped surface 233. The first inclined surface 231 is connected to the first stepped surface 233 through the first longitudinal surface 232. The first longitudinal surface 232 divides the upper end of the first liquid guide tube 23 into two parts. The included angle between the first longitudinal surface 232 and the first stepped surface 233 is 80° to 100° (exemplarily, the first longitudinal surface 232 and the first stepped surface 233 are arranged perpendicular to each other). Along the height direction of the atomizing body 2, the first inclined surface 231 is higher than the first stepped surface 233. The upper end face of the second liquid guide tube 24 includes a second inclined surface 241, a second longitudinal surface 242, and a second stepped surface 243. The second inclined surface 241 is connected to the second stepped surface 243 through the second longitudinal surface 242. The second longitudinal surface 242 divides the upper end of the second liquid guide tube 24 into two parts. The included angle between the second longitudinal surface 242 and the second stepped surface 243 is 80° to 100° (exemplarily, the second longitudinal surface 242 and the second stepped surface 243 are arranged perpendicular to each other). Along the height direction of the atomizing body 2, both the second inclined surface 241 and the first stepped surface 243 are set higher than the second stepped surface 243. For example, as shown in the example... Figure 15 As shown, taking the upper end face of the top cover 251 as the height measurement reference, assuming that the vertical height between the first step surface 233 and the upper end face of the top cover 251 is H1, and the vertical height between the second step surface 243 and the upper end face of the top cover 251 is H2, then H1 > H2. In specific implementation, the difference between H1 and H2 can be set to 1 to 5 mm, that is, the height difference between the first step surface 233 and the second step surface 243 can be set to 1 to 5 mm.

[0092] In this embodiment, based on the above structural design, in the first aspect, the setting of the first inclined surface 231 enables the upper end of the first liquid guide tube 23 to form a pointed structure that facilitates piercing the first flexible seal 13. Similarly, the setting of the second inclined surface 241 enables the upper end of the second liquid guide tube 24 to form a pointed structure that facilitates piercing the second flexible seal 14. Secondly, by dividing the upper end of the first liquid guide tube 23 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 liquid guide tube 23, thereby avoiding the atomizing liquid forming a liquid surface tension at the upper end of the first liquid guide tube 23 and reducing the gas return performance of the first liquid guide tube 23. Similarly, by dividing the upper end of the second liquid guide tube 24 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 liquid guide tube 24, thereby avoiding the atomizing liquid forming a liquid surface tension at the upper end of the second liquid guide tube 24 and reducing the liquid guiding performance of the second liquid guide tube 24. Thirdly, by setting the height of the first step surface 233 to be higher than the height of the second step surface 243, it is easier to make the liquid flow resistance of the first liquid guide tube 23 greater than the liquid flow resistance of the second liquid guide tube 24.

[0093] Correspondingly, embodiments of this application also provide an atomizing component, which is used in a detachable combination with a liquid storage component, such as... Figure 6-9 As shown, the liquid storage assembly includes a first flexible seal 13, a second flexible seal 14, and a liquid reservoir 1 in the electronic atomizing device mentioned in any of the above embodiments. The first flexible seal 13 seals the first liquid guide hole 121, and the second flexible seal 14 seals the second liquid guide hole 122. The atomizing assembly is the atomizing body 2 in the electronic atomizing device mentioned in any of the above embodiments (e.g., Figure 3-5 as well as Figure 10-17 (as shown); where, as Figure 4 , Figure 9 and Figure 15 As shown, when the atomizing component and the liquid storage component are used as a whole, the upper end of the first liquid guide tube 23 pierces the first flexible seal 13, the upper port of the first liquid guide tube 23 is connected to the first storage cavity 110, and part of the first liquid guide tube 23 is sealed with the first liquid guide hole 121. The upper end of the second liquid guide tube 24 pierces the second flexible seal 14, the upper port of the second liquid guide tube 24 is connected to the first storage cavity 110, and part of the second liquid guide tube 24 is sealed with the second liquid guide hole 122.

[0095] It should be noted that other details of the atomizing components and electronic atomizing devices disclosed in this application can be found in the prior art, and will not be repeated here.
