Technical Field

[0002] Traditional electronic atomization devices such as electronic cigarettes are usually designed with an atomizer, which can atomize the aerosol matrix stored therein for users to inhale. However, traditional atomizers usually have leakage. The aerosol matrix (such as tobacco oil, etc.) in the atomizer is easy to leak from the bottom of the atomizer to the outside of the shell. On the one hand, the aerosol matrix leaked outside the shell has an adverse effect on the user's experience.

The outer wall of the anti-leakage element is provided with a plurality of fins surrounding the outer periphery of the first air flow channel. The fins abut against the inner wall of the shell, and capillary grooves are formed between adjacent fins.

[0014] In order to solve the above technical problems, another technical solution adopted by the present invention is: to provide an electronic atomization device. The electronic atomization device includes a first air inlet and a first air outlet. The electronic atomization device also includes a first air flow channel, the first air flow channel is connected to the first air inlet and the first air outlet respectively, and an atomization assembly is arranged in the first air flow channel.

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] See also Figure 1 , Figure 1 It is a schematic structural diagram of the first embodiment of the atomizer of the present invention.

[0031] In order to solve the technical problem of serious leakage of atomizers and electronic atomization devices in the prior art, an embodiment of the present invention provides an atomizer 1. The atomizer 1 includes a first air inlet 11 and a first air outlet 12. The atomizer 1 also includes a first air flow channel 13, which is connected to the first air inlet 11 and the first air outlet 12 respectively, and an atomization assembly 14 is arranged in the first air flow channel 13. The atomizer 1 also includes a second air flow channel 151, and the two ends of the second air flow channel 151 respectively intersect with the first air flow channel 13 to form a first intersection 1511 and a second intersection 1512, wherein the first intersection 1511 is located between the first air outlet 12 and the atomization assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the atomization assembly 14. The atomizer 1 also includes a capillary liquid absorption structure 152, and the capillary liquid absorption structure 152 is connected to the second air flow channel 151. When the first air outlet 12 performs a suction action, the accumulated liquid near the second intersection 1512 in the first air flow channel 13 enters the second air flow channel 151 through the second intersection 1512 and is absorbed by the capillary liquid absorption structure 152. This is described in detail below.

[0032] In one embodiment, the atomizer 1 is a component used to atomize an aerosol matrix in an electronic atomization device. The electronic atomization device using the atomizer 1 of this embodiment may be an electronic cigarette, etc., and the atomizer 1 thereof is used to atomize the smoke oil (i.e., the aerosol matrix) for inhalation by the user. Of course, in other embodiments of the present invention, the electronic atomization device using the atomizer 1 of this embodiment is not limited to the product form of an electronic cigarette. For example, the atomizer 1 of the electronic atomization device can also be used to atomize liquid medicine, etc. The atomized liquid medicine is inhaled by the user to assist the user's drug treatment, etc. The following description takes the product form of the electronic atomization device using the atomizer 1 of this embodiment as an electronic cigarette as an example, which is only for the purpose of discussion and does not constitute a limitation.

[0033] Specifically, the atomizer 1 includes a first air inlet 11 and a first air outlet 12, and a first air flow channel 13 respectively connecting the first air inlet 11 and the first air outlet 12. When the user inhales, that is, the first air outlet 12 inhales, the outside air enters the first air flow channel 13 from the first air inlet 11, and flows toward the first air outlet 12 along the first air flow channel 13.

[0034] Furthermore, an atomizing assembly 14 is provided in the first air flow channel 13. The atomizing assembly 14 is a component in the atomizer 1 for atomizing the aerosol matrix. When the user inhales, the air entering the first air flow channel 13 from the first air inlet 11 will carry the aerosol matrix atomized by the atomizing assembly 14 to the first air outlet 12, and will be output from the first air outlet 12 for the user to inhale.

[0035] Optionally, the atomizing component 14 is preferably a porous heating element, which absorbs the aerosol matrix through capillary force and generates heat to atomize the aerosol matrix. Preferably, the atomizing component 14 can be a porous ceramic heating element, etc., and a heating film can be further provided at the bottom thereof. Of course, in other embodiments of the present invention, the atomizing component 14 can also be a design of a combination of fiber cotton and heating wire, which is not limited here.

[0036] The atomizer 1 further includes a second airflow channel 151. The second airflow channel 151 is separated from the first airflow channel 13, and two ends of the second airflow channel 151 intersect with the first airflow channel 13 to form a first intersection 1511 and a second intersection 1512, respectively.

[0037] The atomizer 1 further includes a capillary liquid absorption structure 152 , which is connected to the second air flow channel 151 and is used for absorbing the accumulated liquid entering the second air flow channel 151 .

[0038] Since the atomizing assembly 14 is designed in the first air flow channel 13, the aerosol matrix absorbed by the atomizing assembly 14 will inevitably remain in the first air flow channel 13. In addition, since the temperature of the aerosol matrix after atomization is relatively high and the temperature of the inner wall of the first air flow channel 13 is relatively low, the temperature of the aerosol matrix after atomization will drop sharply and condense when it contacts the inner wall of the first air flow channel 13, and the condensed aerosol matrix will remain in the first air flow channel 13. Therefore, the above factors will cause the aerosol matrix to remain in the first air flow channel 13, i.e., form effusion. When there is too much effusion in the first air flow channel 13, it will inevitably leak to the outside of the atomizer 1.

[0039] In view of this, the second air flow channel 151 is designed in this embodiment. Among them, the first intersection 1511 is located between the first air outlet 12 and the atomizer assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the atomizer assembly 14. In other words, the first intersection 1511 is closer to the first air outlet 12 than the second intersection 1512. . In this way, when the first air outlet 12 is sucked, an air flow from the first air inlet 11 to the first air outlet 12 will be generated in the first air flow channel 13, and the air pressure of the first air flow channel 13 at the first intersection 1511 will be lower than the air pressure of the second air flow channel 151 at the first intersection 1511, and the air pressure of the first air flow channel 13 at the second intersection 1512 will be higher than the air pressure of the second air flow channel 151 at the second intersection 1512. Therefore, the pressure difference between the first air flow channel 13 at the second intersection 1512 and the second air flow channel 151 will drive the accumulated liquid in the first air flow channel 13 near the second intersection 1512 to enter the second air flow channel 151 through the second intersection 1512 and be absorbed by the capillary absorption structure 152, thereby reducing the accumulated liquid in the first air flow channel 13, which is beneficial to alleviate the leakage of the atomizer 1 and improve the user experience.

[0040] It should be noted that when the first air outlet 12 is sucking, the outside air enters the first air flow channel 13 from the first air inlet 11, and an air flow from the first air inlet 11 to the first air outlet 12 is generated in the first air flow channel 13. At the same time, part of the air entering the first air flow channel 13 from the first air inlet 11 will flow into the second air flow channel 151 from the second intersection 1512, and the air in the second air flow channel 151 will converge from the first intersection 1511 to the first air flow channel 13, forming a complete air flow path. Figure 1Indicated by the dotted arrow. That is to say, when the first air outlet 12 is sucked, a pressure difference will be generated between the first air flow channel 13 and the second air flow channel 151 at the second intersection 1512, thereby driving the accumulated liquid in the first air flow channel 13 to flow into the second air flow channel 151 through the second intersection 1512. When the first air outlet 12 is not sucked, that is, when the user is not sucking, the air pressure in the first air flow channel 13 is about a standard atmospheric pressure, about 101.325 kPa, and the difference between the air pressure in the first air flow channel 13 and the second air flow channel 151 is not obvious. At this time, the amount of the accumulated liquid in the first air flow channel 13 absorbed by the second air flow channel 151 is relatively limited.

[0041] Furthermore, the second airflow channel 151 of this embodiment is used to cooperate with the capillary liquid absorption structure 152 to absorb the accumulated liquid in the first airflow channel 13, and is not a cavity for storing aerosol matrix in the atomizer 1. For example, the electronic atomization device in the form of the above-mentioned electronic cigarette product usually has a smoke oil cavity designed in the atomizer 1 to store smoke oil (i.e., aerosol matrix).

[0042] The first air inlet 11 and the first air outlet 12 of the atomizer 1 of this embodiment can be arranged in a straight line at intervals, that is, the atomizer 1 of this embodiment adopts a straight liquid design. Of course, in other embodiments of the present invention, the atomizer 1 can also adopt other forms of design besides the straight liquid design, which is not limited here.

[0043] In one embodiment, the second air flow channel 151 is connected to the capillary liquid absorption structure 152 for absorbing the accumulated liquid entering the second air flow channel 151 from the second intersection 1512 .

[0044] Furthermore, the capillary liquid absorption structure 152 includes a plurality of capillary grooves 1521, and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second air flow channel 151 from the second intersection 1512 through capillary force. Figure 1 In addition, a plurality of capillary grooves 1521 are sequentially arranged at intervals along the extension direction of the second air flow channel 151 and connected to the second air flow channel 151, wherein the capillary grooves 1521 relatively close to the second intersection 1512 are preferentially used to absorb and store the accumulated liquid entering the second air flow channel 151. The specific structural design and implementation of the capillary grooves 1521 will be described below.

[0045] Please continue reading Figure 1 In one embodiment, the first air flow channel 13 includes an air outlet channel 131 and an atomizing chamber 132, wherein an atomizing assembly 14 is disposed in the atomizing chamber 132. The air outlet channel 131 is connected to the atomizing chamber 132 and the first air outlet 12, and the atomizing chamber 132 is also connected to the first air inlet 11. In other words, the first air outlet 12, the air outlet channel 131, the atomizing chamber 132 and the first air inlet 11 are connected in sequence.

[0046] The cross-sectional area of ​​the air outlet channel 131 is smaller than the cross-sectional area of ​​the atomizing chamber 132. When the airflow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, the cross-sectional area of ​​the air outlet channel 131 is smaller, the airflow velocity in the air outlet channel 131 is larger, and the corresponding air pressure is lower, which is conducive to increasing the pressure difference between the air outlet channel 131 and the atomizing chamber 132, so that the atomized aerosol matrix can be better provided to the user for inhalation.

[0047] The cross sections of the gas outlet channel 131 and the atomizing chamber 132 are perpendicular to their respective extension directions, and the extension direction of the gas outlet channel 131 is defined as the direction extending from the atomizing chamber 132 to the first gas outlet 12, and the extension direction of the atomizing chamber 132 is defined as the direction extending from the first gas inlet 11 to the gas outlet channel 131. For example, Figure 1 In the straight liquid atomizer 1 shown, the air outlet channel 131 and the atomizing chamber 132 extend in the direction from the first air inlet 11 to the first air outlet 12 .

[0048] Furthermore, the first intersection 1511 is provided at the air outlet channel 131, and the second intersection 1512 is provided at the atomizing chamber 132. Thus, when an airflow from the first air inlet 11 to the first air outlet 12 is generated in the first air flow channel 13, the air pressure of the air outlet channel 131 is lower than the air pressure of the second air flow channel 151, and the air in the second air flow channel 151 flows into the air outlet channel 131 through the first intersection 1511, while the air pressure of the atomizing chamber 132 is higher than the air pressure of the second air flow channel 151, and the air in the atomizing chamber 132 flows into the second air flow channel 151 through the second intersection 1512, thereby forming the above-mentioned complete air flow passage.

[0049] Of course, in other embodiments of the present invention, since when the first air outlet 12 is sucked, an airflow is generated in the first air flow channel 13 from the first air inlet 11 to the first air outlet 12, the air pressure in the first air flow channel 13 is gradually reduced in the direction from the first air inlet 11 to the first air outlet 12. In view of this, the first intersection 1511 and the second intersection 1512 can also be both arranged in the air outlet channel 131, or both arranged in the atomizing chamber 132. As long as the first intersection 1511 is closer to the first air outlet 12 relative to the second intersection 1512, the design of the embodiment of the present invention to alleviate the leakage of the atomizer 1 can be realized. In a preferred embodiment, the second intersection 1512 is located at the bottom of the atomizing chamber 132, so that the accumulated liquid at the bottom of the atomizing chamber 132 can be absorbed by the capillary liquid absorption structure 152 along the second air flow channel 151 during suction.

[0050] Specifically, when an airflow from the first air inlet 11 to the first air outlet 12 is generated in the first air flow channel 13, the air pressure in the atomization chamber 132 is P1, the air pressure in the air outlet channel 131 is P2, and the air pressure in the second air flow channel 151 is P3, wherein P1>P3>P2.

[0051] The air pressure in the atomizing chamber 132 is greater than the air pressure in the second air flow channel 151 . The pressure difference between the atomizing chamber 132 at the second intersection 1512 and the second air flow channel 151 will drive the accumulated liquid in the atomizing chamber 132 near the second intersection 1512 to enter the second air flow channel 151 through the second intersection 1512 and be absorbed by the capillary absorption structure 152 .

[0052] In one embodiment, the volume of the accommodation space in the second air flow channel 151 and the capillary liquid absorption structure 152 is smaller than the volume of the accommodation space in the atomizing chamber 132. Wherein, the accommodation space is defined as the space in the cavity for storing air and aerosol matrix. The volume of the accommodation space in the second air flow channel 151 and the capillary liquid absorption structure 152 is small. When the airflow from the first air inlet 11 to the first air outlet 12 is generated in the first air flow channel 13, the airflow velocity in the second air flow channel 151 and the capillary liquid absorption structure 152 is fast, and the corresponding air pressure is small, which is conducive to increasing the pressure difference between the second air flow channel 151 and the atomizing chamber 132, that is, increasing the force that drives the accumulated liquid in the atomizing chamber 132 to enter the second air flow channel 151, which is further conducive to reducing the accumulated liquid in the first air flow channel 13, especially reducing the accumulated liquid at the bottom of the atomizing chamber 132, thereby alleviating the leakage of the atomizer 1 and improving the user's experience.

[0053] Furthermore, the second airflow channel 151 is separated from the first airflow channel 13. Specifically, the second airflow channel 151 is separated from the air outlet channel 131 and the atomizing chamber 132, respectively, and the second airflow channel 151 is connected with the air outlet channel 131 and the atomizing chamber 132 through the first intersection 1511 and the second intersection 1512. The separation is conducive to ensuring the pressure difference between the second airflow channel 151 and the air outlet channel 131 and the atomizing chamber 132, ensuring that there is a sufficient pressure difference to drive the accumulated liquid in the atomizing chamber 132 into the second airflow channel 151, and also ensuring the formation of the above-mentioned complete airflow passage.

[0054] Optionally, a partition 16 may be provided between the second air flow channel 151 and the first air flow channel 13, such as Figure 1 As shown, the second air flow channel 151 and the first air flow channel 13 are separated from each other, which is not limited here.

[0055] It should be noted that the atomizer 1 may also include a liquid leakage-proof cavity 15, in which the second air flow channel 151 and the capillary liquid absorption structure 152 are arranged, the liquid leakage-proof cavity 15 is separated from the first air flow channel 13, and the liquid leakage-proof cavity 15 is connected to the first air flow channel 13 through the first intersection 1511 and the second intersection 1512 respectively.

[0056] Of course, in other embodiments of the present invention, the second air flow channel 151 and the capillary liquid absorption structure 152 can also be designed to be integrally formed in the atomizer 1, instead of additionally designing an anti-leakage cavity 15 in the atomizer 1 as described above, and then setting the second air flow channel 151 and the capillary liquid absorption structure 152 in the anti-leakage cavity 15, which will be explained below.

[0057] In summary, the atomizer provided by the present invention has two ends of the second air flow channel that intersect with the first air flow channel to form a first intersection and a second intersection, wherein the first intersection is located between the first air outlet and the atomizing assembly, and the second intersection is located between the first air inlet and the atomizing assembly. In other words, the first intersection is closer to the first air outlet relative to the second intersection. In this way, when the first air outlet is sucked, an airflow from the first air inlet to the first air outlet will be generated in the first air flow channel, and the air pressure of the first air flow channel at the first intersection will be less than the air pressure of the second air flow channel at the first intersection, and the air pressure of the first air flow channel at the second intersection will be greater than the air pressure of the second air flow channel at the second intersection. Therefore, the pressure difference between the first air flow channel and the second air flow channel at the second intersection will drive the accumulated liquid in the first air flow channel near the second intersection to enter the second air flow channel through the second intersection and be absorbed by the capillary absorption structure, so as to reduce the accumulated liquid in the first air flow channel, especially reduce the accumulated liquid at the bottom of the atomization chamber, thereby helping to alleviate the leakage of the atomizer and the electronic atomization device, thereby improving the user's experience and reducing the risk of damage to the host due to the aerosol matrix penetrating into the host of the electronic atomization device.

Figure 4 It is a schematic structural diagram of an embodiment of a liquid leakage prevention element of the present invention.

[0059] In one embodiment, the atomizer 1 is as described in the above embodiment, and has a first air inlet 11 and a first air outlet 12 and a first air flow channel 13 connecting the first air inlet 11 and the first air outlet 12. The atomizer 1 also includes a housing 17, and the first air inlet 11 and the first air outlet 12 are opened on the housing 17.

The liquid storage cavity 19 is connected to the anti-leakage liquid element 18, and is further connected to the atomization assembly 14 in the anti-leakage liquid element 18, so that the aerosol matrix in the liquid storage cavity 19 can be heated and atomized by the atomization assembly 14, as shown in FIG. Figure 3 shown.

[0063] In one embodiment, a gap 183 is provided inside the liquid leakage prevention element 18. The inner wall of the liquid leakage prevention element 18 of the gap 183 and the inner wall of the housing 17 surround to form a first air flow channel 13 provided in the liquid leakage prevention element 18, and the outer wall of the liquid leakage prevention element 18 and the inner wall of the housing 17 surround to form a second air flow channel 151. In addition, the capillary liquid absorption structure 152 is provided in the space surrounded by the outer wall of the liquid leakage prevention element 18 and the inner wall of the housing 17, as shown in FIG. Figure 4 As shown, Figure 4 The housing 17 is omitted.

[0064] Of course, in other embodiments of the present invention, the vacant portion 183 of the liquid leakage prevention element 18 has a shell structure independent of the shell 17, and can also surround and form the first airflow channel 13 provided in the liquid leakage prevention element 18, without relying on the inner wall of the shell 17. Similarly, the portion of the liquid leakage prevention element 18 in the second airflow channel 151 can also have a shell structure independent of the shell 17, and it and the outer wall of the liquid leakage prevention element 18 can also surround and form the second airflow channel 151, which is not limited here.

[0065] Please continue reading Figure 4 . Further, a dam 184 is provided on the outer wall of the anti-leakage element 18, and the dam 184 abuts against the inner wall of the housing 17. The dam 184 is used to separate the second airflow channel 151 and the first airflow channel 13, so as to realize the separation setting of the second airflow channel 151 and the first airflow channel 13. And a first connecting groove 185 is provided in the portion of the dam 184 corresponding to the first intersection 1511, so that the first airflow channel 13 and the second airflow channel 151 intersect to form the first intersection 1511. A second connecting groove 186 is provided in the portion of the dam 184 corresponding to the second intersection 1512, so that the first airflow channel 13 and the second airflow channel 151 intersect to form the second intersection 1512. Among them, the second connecting groove 186 can also be a groove body similar to a capillary groove, and the accumulated liquid in the first airflow channel 13 is also absorbed by capillary force.

[0066] Figure 4 The atomizing chamber 132 and part of the air outlet channel 131 of the first air flow channel 13 are arranged in the anti-leakage element 18. The first connecting groove 185 is arranged corresponding to the air outlet channel 131 in the anti-leakage element 18, and the second connecting groove 186 is arranged corresponding to the atomizing chamber 132 in the anti-leakage element 18.

[0067] and Figure 4 It is also shown that the second air flow channel 151 and the capillary liquid absorption structure 152 are respectively provided on the opposite sides of the first air flow channel 13 in the liquid leakage prevention element 18. Further, the second air flow channel 151 and the capillary liquid absorption structure 152 on both sides of the first air flow channel 13 in the liquid leakage prevention element 18 are preferably arranged in a mirror-symmetrical manner. Further, the liquid leakage prevention element 18 has a first intersection 1511 and a second intersection 1512 on both sides in the predetermined direction, and the liquid leakage prevention element 18 has a first connecting groove 185 and a second connecting groove 186 arranged corresponding to the first intersection 1511 and the second intersection 1512 on both sides in the predetermined direction. The first air flow channel 13 in the liquid leakage prevention element 18 penetrates the liquid leakage prevention element 18 along the predetermined direction, and then communicates with the second air flow channels 151 on both sides in the predetermined direction. Wherein, the predetermined direction (such as Figure 4 The relative directions of the second air flow channels 151 on both sides of the first air flow channel 13 in the anti-leakage element 18 are perpendicular to each other (as shown by the arrow X in the middle). Figure 4 , and is perpendicular to the extension direction of the first air flow channel 13 in the anti-leakage element 18 (as shown by the arrow Y in the figure). Figure 4 (as indicated by the arrow Z in the middle).

[0068] Please continue reading Figure 4In one embodiment, the outer wall of the anti-leakage element 18 is provided with a plurality of capillary grooves 1521 surrounding the outer periphery of the first air flow channel 13 , and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second air flow channel 151 from the second intersection 1512 through capillary force.

[0069] Specifically, the outer wall of the anti-leakage element 18 is provided with a plurality of fins 1522 surrounding the outer periphery of the first airflow channel 13, and capillary grooves 1521 are formed between adjacent fins 1522. In addition, the fins 1522 abut against the inner wall of the housing 17 to ensure that the capillary grooves 1521 can absorb and store the accumulated liquid through capillary force.

[0070] Furthermore, the plurality of capillary grooves 1521 are arranged at intervals and parallel to each other along the extension direction of the second airflow channel 151. After the capillary grooves 1521 relatively close to the second intersection 1512 are full of accumulated liquid, the capillary grooves 1521 relatively far from the second intersection 1512 continue to absorb the accumulated liquid until the storage volume of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation. When the storage volume of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation, the anti-leakage element 18 can be disassembled for cleaning so as to be used again, or a new atomizer 1 can be replaced, which is not limited here.

[0071] It should be noted that the part of the anti-leakage element 18 where the second airflow channel 151 and the capillary liquid absorption structure 152 are located can be a detachable structure, so that the second airflow channel 151 and the capillary liquid absorption structure 152 can be easily assembled into the anti-leakage element 18, and it can also be convenient to clean the anti-leakage element 18 as described above. Of course, in other embodiments of the present invention, the part of the anti-leakage element 18 where the second airflow channel 151 and the capillary liquid absorption structure 152 are located can also be an integral structure with the original anti-leakage element 18 and cannot be disassembled, which is not limited here.

[0072] See also Figure 5 and Figure 6 . Figure 5 The figure shows the situation of liquid accumulation in the first air flow channel 31 of the conventional atomizer 3 when the user takes 60, 90 and 120 puffs. Figure 6 The embodiment of the atomizer 1 shows the situation of liquid accumulation in the first air flow channel 13 when the user takes 60, 90 and 120 puffs of the atomizer 1, and Figure 6 It also shows the situation that the capillary absorption structure 152 absorbs the accumulated liquid when the user takes 60, 90 and 120 puffs of the atomizer 1 of this embodiment. It can be seen that the situation of the accumulated liquid in the first air flow channel 13 of the atomizer 1 of this embodiment is significantly improved.

[0073] In summary, the atomizer provided by the present invention has a portion of the first air flow channel connected to the first intersection closer to the first air outlet in the extension direction of the first air flow channel relative to the portion of the first air flow channel connected to the second intersection. In this way, when the user inhales, an air flow from the first air inlet to the first air outlet will be generated in the first air flow channel, and the air pressure of the portion of the first air flow channel connected to the second intersection is greater than the air pressure at the second intersection of the second air flow channel, that is, there is a pressure difference on both sides of the second intersection, and the pressure difference on both sides of the second intersection will drive the accumulated liquid in the first air flow channel to flow into the second air flow channel through the second intersection and be absorbed by the capillary liquid absorption structure, so as to reduce the accumulated liquid in the first air flow channel, especially reduce the accumulated liquid at the bottom of the atomization chamber, thereby helping to alleviate the leakage of the atomizer and improve the user's experience.

The electronic atomization device also includes a capillary liquid absorption structure 152, which is connected to the second air flow channel 151. When the first air outlet 12 is sucking, the accumulated liquid near the second intersection 1512 in the first air flow channel 13 enters the second air flow channel 151 through the second intersection 1512 and is absorbed by the capillary liquid absorption structure 152. The details have been described in detail in the above embodiment and will not be repeated here.
