In order to make the objects, 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 with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

In order to solve the technical problem of poor liquid leakage prevention effect of the electronic atomization device in the prior art, an embodiment of the invention provides an atomizer. The atomizer includes an air inlet, an air outlet, and an airflow channel. The airflow channel is respectively communicated with the air inlet and the air outlet, and an atomizing core is arranged in the airflow channel. This atomizer still includes first capillary imbibition structure and second capillary imbibition structure, and air current passageway between air inlet and the atomizing core is located to first capillary imbibition structure and second capillary imbibition structure to first capillary imbibition structure is located between atomizing core and the second capillary imbibition structure. Wherein, have the clearance between first capillary imbibition structure and the second capillary imbibition structure, the gas that gets into from the gas inlet reaches the atomizing core through clearance, first capillary imbibition structure in proper order. As described in detail below.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an atomizer according to an embodiment of the present invention, and fig. 2 is a schematic structural sectional diagram of the atomizer shown in fig. 1 in a direction a-a.

In one embodiment, the nebulizer 10 may be in the form of an electronic cigarette, for example. Of course, a medical atomizing apparatus and the like applied to the medical field may be used. The following description is given by way of example, and not by way of limitation, of a nebulizer 10 in the form of an electronic cigarette.

Specifically, the atomizer 10 includes an air inlet 11, an air outlet 12, and an air flow passage 13. The air flow channel 13 communicates with the air inlet 11 and the air outlet 12, respectively, and an atomizing core 14 is disposed in the air flow channel 13, wherein the atomizing core 14 is used for atomizing aerosol substrate (such as tobacco tar, liquid medicine, etc.) in the atomizer 10.

The position of the air inlet 11 is the position where the atomizer 10 is to be fed. When the user sucks, external air enters the air flow channel 13 from the air inlet 11 to carry the aerosol substrate atomized by the atomizing core 14 in the air flow channel 13 to the air outlet 12 and is output to the user along the air outlet 12 for the user to suck.

Alternatively, the atomizing wick 14 may be a porous heat-generating body that absorbs the aerosol substrate by capillary force and generates heat to atomize the aerosol substrate. Preferably, the atomizing core 14 may be a porous ceramic heat-generating body or the like, which may be further provided with a heat-generating film. Of course, in other embodiments of the present invention, the atomizing core 14 may also be a design of collocating fiber cotton and heating wire, and is not limited herein.

The atomizer 10 of the present embodiment further comprises a first capillary wicking structure 15 and a second capillary wicking structure 16. The first capillary wicking structure 15 and the second capillary wicking structure 16 are provided in the air flow passage 13 between the air inlet 11 and the atomizing wick 14, and the first capillary wicking structure 15 is located between the atomizing wick 14 and the second capillary wicking structure 16.

It should be noted that, since the first capillary wicking structure 15 is close to the atomizing wick 14 relative to the second capillary wicking structure 16, the condensed aerosol substrate in the air flow channel 13 will be absorbed by the first capillary wicking structure 15 first. And since the first capillary wicking structure 15 communicates with the second capillary wicking structure 16, after the amount of liquid absorbed by the first capillary wicking structure 15 reaches a threshold value, the liquid (i.e., aerosol matrix) in the first capillary wicking structure 15 further enters the second capillary wicking structure 16 to be absorbed by the second capillary wicking structure 16.

Specifically, when the accumulated liquid in the gas flow channel 13 is small, the aerosol substrate is absorbed by the first capillary wicking structure 15 by capillary force to lock the aerosol substrate. And when the liquid loading in the air flow channel 13 is large, and the amount of the liquid loading absorbed by the first capillary liquid absorption structure 15 reaches the threshold value, the aerosol substrate in the first capillary liquid absorption structure 15 further enters the second capillary liquid absorption structure 16 and is absorbed by the second capillary liquid absorption structure 16 through capillary force.

That is to say, the atomizer 10 of this embodiment increases its stock solution (store hydrops promptly, the same below) volume through first capillary imbibition structure 15 and second capillary imbibition structure 16, can reduce the risk that the hydrops leaked, and then improves the leak protection liquid effect of atomizer 10.

Also, the first capillary-wicking structure 15 and the second capillary-wicking structure 16 of the present embodiment have a gap 17 therebetween. The gas entering from the gas inlet 11 sequentially passes through the gap 17 and the first capillary liquid absorption structure 15 to reach the atomization core 14, so that the gas is allowed to be uniformly mixed in the gap 17 and uniformly distributed to the first capillary liquid absorption structure 15, and then the atomized aerosol substrate is output to a user through the first capillary liquid absorption structure 15. Moreover, the first capillary liquid absorption structure 15 also plays a role of rectification, so that the flow speed and the flow direction of the air flow passing through the first capillary liquid absorption structure 15 are relatively consistent, the atomization core 14 is better covered by the air flow, the air flow in the atomizer 10 is optimized to better carry the atomized aerosol substrate at the atomization core 14 to the air outlet 12, further, the aerosol carrying the aerosol substrate is better provided for a user, and the user experience of the atomizer 10 is favorably improved.

Furthermore, the aerosol substrate absorbed in the first capillary wicking structure 15 is driven by the airflow to return to the atomizing wick 14 for re-atomization when being sucked by the user, which can improve the utilization of the aerosol substrate of the atomizer 10 of the present embodiment.

Alternatively, the first and second capillary wicking structures 15, 16 may be capillary grooves or the like having a capillary force capable of absorbing the aerosol substrate by the capillary force. Of course, the first capillary liquid absorption structure 15 and the second capillary liquid absorption structure 16 may be other structures having capillary force, for example, the surface of the air flow channel 13 is subjected to roughening treatment such as grinding, so as to form structures having capillary force in the form of frosted surface, lines, etc., that is, the first capillary liquid absorption structure 15 and the second capillary liquid absorption structure 16. As will be explained below.

In one embodiment, the first capillary wicking structure 15 comprises a plurality of capillary channels that extend in parallel and have the same cross-sectional area, such that the flow velocity and direction of the air flow through each capillary channel is the same, thereby optimizing the flow straightening action of the first capillary wicking structure 15. Further, the plurality of capillary grooves may extend in a direction close to the air outlet 12.

Referring to fig. 2 and 3, fig. 3 is a schematic structural view of a portion of the atomizer shown in fig. 2.

In one embodiment, the atomizer 10 has a plurality of air inlets 11. Fig. 2 and 3 show the case where the atomizer 10 has two air inlets 11. After reaching the gap 17, the gas entering from the two gas inlets 11 can be mixed at the gap 17 and then reach the atomizing core 14 through the first capillary liquid absorption structure 15, specifically, the gas entering from the two gas inlets 11 is mixed at the gap 17 and uniformly distributed into the first capillary liquid absorption structure 15, and the gas flow in the atomizer 10 is optimized in cooperation with the rectification action of the first capillary liquid absorption structure 15 so as to better carry the aerosol matrix atomized at the atomizing core 14 to the gas outlet 12.

Of course, in other embodiments of the present invention, the atomizer 10 may have only one gas inlet 11, and the gas entering from the gas inlet 11 passes through the gap 17 and the first capillary wicking structure 15 to reach the atomizing core 14 in sequence, which is not limited herein.

Please continue to refer to fig. 2 and 3. In an embodiment, after the user stops sucking, the aerosol in the atomizer 10 will flow back, and in order to prevent the backflow aerosol from directly leaking from the air inlet 11 to cause a liquid leakage problem, a blocking member 131 is disposed in the air flow channel 13 of this embodiment, the blocking member 131 forms a block between the gap 17 and the air inlet 11 to limit the direct communication between the gap 17 and the air inlet 11, so that the gap 17 is communicated with the air inlet 11 through the second capillary liquid-absorbing structure 16.

Through the above manner, the reflowing aerosol firstly passes through the first capillary liquid absorption structure 15, wherein the condensed aerosol matrix is firstly absorbed by the first capillary liquid absorption structure 15, and the reflowing aerosol which passes through the first capillary liquid absorption structure 15 and reaches the gap 17 cannot directly escape from the air inlet 11 under the limitation of the blocking piece 131, but enters the second capillary liquid absorption structure 16, and through the secondary absorption of the second capillary liquid absorption structure 16, most aerosol matrices in the reflowing aerosol are all locked in the atomizer 10 and cannot leak from the atomizer 10, wherein the blocking piece 131 is arranged to reduce the risk that the reflowing aerosol directly escapes from the air inlet 11, which is beneficial to further reducing the risk of liquid leakage and improving the liquid leakage prevention effect of the atomizer 10.

It should be noted that the air inlet path of the atomizer 10 of the present embodiment is air inlet 11-second capillary liquid absorbing structure 16-gap 17-first capillary liquid absorbing structure 15-atomizing core 14-air outlet 12-user, wherein the air inlet path at the bottom of the air flow channel is shown by the dashed arrow in fig. 4. The aerosol backflow path (when the user stops pumping) of the atomizer 10 of the present embodiment is the reverse of the aforementioned air inlet path, specifically, the air outlet 12-the atomizing core 14-the first capillary wicking structure 15-the gap 17-the second capillary wicking structure 16-the air inlet 11, wherein due to the wicking action of the second capillary wicking structure 16 and the limitation of the blocking member 131, the backflow aerosol hardly escapes from the air inlet 11, and the risk of liquid leakage is greatly reduced.

Further, with continued reference to fig. 2 and 3, the barrier member 131 includes a first barrier member 1311 and a second barrier member 1312, the first barrier member 1311 and the second barrier member 1312 are disposed at an angle on a plane and cooperate to define a gap 17, wherein after the first barrier member 1311 and the second barrier member 1312 are abutted with the second capillary wicking structure 16, the gap 17 is abutted with the second capillary wicking structure 16, such that the gap 17 is communicated with the air inlet 11 through the second capillary wicking structure 16. In this way, the return atomized gas can directly enter the second capillary wicking structure 16 only through the gap 17 and cannot directly escape from the air inlet 11 under the restriction of the first barrier 1311 and the second barrier 1312.

Further, with continued reference to fig. 2 to 4, the airflow passage 13 includes an air inlet passage 134 and an intermediate passage 135 which are communicated with each other, the air inlet passage 134 is further communicated with the air inlet 11, and the intermediate passage 135 is further communicated with the air outlet 12. Wherein the atomizing wick 14, the first capillary wicking structure 15, and the second capillary wicking structure 16 are provided in the intermediate passage 135.

Still further, the gas flow channel 13 may further include an outlet channel 136, and the intermediate channel 135 communicates with the gas outlet 12 through the outlet channel 136.

The second capillary wicking structure 16 is disposed near the port 1341 of the air inlet channel 134 communicating with the intermediate channel 135, wherein the other port of the air inlet channel 134 opposite to the port 1341 is the air inlet 11. The intermediate passage 135 is provided with a first bank 181 and a second bank 182 that surround the periphery of a port 1341 of the intake passage 134 communicating with the intermediate passage 135. The first dam 181 is disposed adjacent to the gap 17 opposite the second dam 182 and the first dam 181 forms a barrier between the gap 17 and the air inlet passage 134 to restrict the gap 17 from communicating directly with the air inlet passage 134, thereby allowing the gap 17 to communicate with the air inlet passage 134 through the second wicking structure 16. Wherein the first bank 181 may be a part of the first barrier 1311 or the second barrier 1312, fig. 3 illustrates a case where the first bank 181 is a part of the first barrier 1311, which will be explained in detail below.

Further, the height of the first dam 181 is higher than the height of the second dam 182 to form a vent 183 between the first dam 181 and the second dam 182, the gas inlet channel 134 communicates with the second capillary wicking structure 16 through the vent 183 and further communicates with the gap 17, and the gas entering from the gas inlet channel 134 needs to be diverted through the vent 183 into the second capillary wicking structure 16 and further to the gap 17, as shown in fig. 3 and 4, wherein the path of the gas entering from the port 1341 of the gas inlet channel communicating with the middle channel and diverted through the vent 183 into the second capillary wicking structure 16 is shown by the dashed arrow in fig. 4.

Fig. 4 shows the situation that the first dam 181, the second dam 182 and the sidewall of the bottom of the middle channel 135 cooperate to surround the port 1341 of the air inlet channel communicating with the middle channel, wherein the second dam 182 is respectively disposed on both sides of the first dam 181, that is, the vent holes 183 are respectively disposed on both sides of the first dam 181. That is, the gas entering from the gas inlet passage is diverted into the second capillary wicking structure 16 through the vent holes 183 at both sides of the first bank 181.

Fig. 3 and 4 also show that two opposite air inlet channels 134 are arranged at the bottom of the middle channel 135, the gap 17 is arranged opposite to the second capillary wicking structure 16 between the two air inlet channels 134, and the air entering from the two air inlet channels 134 is diverted to enter the second capillary wicking structure 16 between the two air inlet channels 134, and after confluence, enters the gap 17 together, and then reaches the atomizing core 14 through the first capillary wicking structure 15 to carry the atomized aerosol substrate out to the user.

Further, with continued reference to fig. 4, the first dam 181 and the second dam 182 are also used to separate the air inlet channel from the second capillary wicking structure 16, specifically, to separate the port 1341 of the air inlet channel communicating with the atomizing chamber from the second capillary wicking structure 16. As such, even when the second capillary wicking structure 16 absorbs a large amount of aerosol substrate, the aerosol substrate absorbed by the second capillary wicking structure 16 does not leak from the air intake passage, further reducing the risk of leakage.

Further, the first bank 181 and the second bank 182 have a height higher than that of the second capillary-wicking structure 16, and the risk of liquid leakage can be further reduced in addition to the provision of the first bank 181 and the second bank 182.

Please continue to refer to fig. 3. In one embodiment, the orthographic projection of the port 1341 of the air inlet passage 134 communicating with the intermediate passage 135 on the reference plane is located outside the orthographic projection of the gap 17 on the reference plane, wherein the reference plane (as indicated by the plane α in fig. 3) is perpendicular to the relative direction of the first and second capillary wicking structures 15, 16 (the relative direction of the first and second capillary wicking structures 15, 16 is indicated by the arrow X in fig. 3). That is, for a straight-liquid atomizer, the reference plane is perpendicular to the central axis of the atomizer.

That is to say, the air inlet channel 134 and the gap 17 of the present embodiment are disposed in a staggered manner on the reference plane, and are also used to avoid the problem of liquid leakage caused by the atomizing gas flowing back from the gap 17 directly escaping from the air inlet channel 134, which is beneficial to further reducing the risk of liquid leakage and improving the liquid leakage prevention effect of the atomizer 10.

Fig. 3 shows that the orthographic projections of the two intake passages 134 on the reference plane are located on opposite sides of the orthographic projection of the gap 17 on the reference plane, respectively.

Please continue to refer to fig. 3. In one embodiment, the air inlet passage 134 includes at least two segments of first sub-passages 1342, and adjacent first sub-passages 1342 are connected by a second sub-passage 1343, wherein the extending direction of the first sub-passages 1342 is different from the extending direction of the second sub-passages 1343. That is to say, air inlet channel 134 is the form of extending of winding, and air inlet channel 134 that winding extends has increased the atomizing gas of backward flow and has passed through the difficulty that air inlet channel 134 escaped to further reduce the risk of weeping, be favorable to improving the leak protection effect of atomizer.

Referring to fig. 2, fig. 3 and fig. 5, fig. 5 is a schematic diagram of an exploded structure of an embodiment of an atomizing core, a first carrier and a second carrier according to the present invention.

In an embodiment, the nebulizer 10 further comprises a first carrier 132 and a second carrier 133. The first carrier 132 and the second carrier 133 are butted to form the gas flow channel 13, and a cavity formed by butting the first carrier 132 and the second carrier 133 is used for gas to flow. The atomizing wick 14 and the first capillary wicking structure 15 are provided in the first carrier 132 and the first carrier 132 communicates with the air outlet 12. The air inlet 11 and the second capillary wicking structure 16 are provided in the second carrier 133.

That is, the air flow channel 13 of the atomizer 10 of the present embodiment is designed to be a split structure, so as to facilitate the injection molding of the components. Specifically, aerosol substrate leaking at the atomizing wick 14 on the first carrier 132 is first absorbed by the first capillary wicking structure 15 on the first carrier 132. When the amount of liquid loading absorbed by the first capillary wicking structure 15 reaches a threshold value, the aerosol substrate in the first capillary wicking structure 15 will further seep down to the second capillary wicking structure 16. Because of the extremely large liquid storage volume of the second capillary wicking structure 16 on the second carrier member 133, it is able to absorb a substantial portion of the downwardly-permeated aerosol substrate while preventing the aerosol substrate from leaking out of the atomizer 10.

Specifically, the first dam 181 of the above-described embodiment is provided to the second carrier 133, the portion of the first carrier 132 abutting the second carrier 133 constitutes the first stopper 1311 of the above-described embodiment together with the first dam 181, and the second stopper 1312 of the above-described embodiment is also provided to the first carrier 132, as shown in fig. 3.

Of course, in other embodiments of the present invention, the first carrier 132 and the second carrier 133 may also be integrally formed by 3D printing, and are not limited herein.

Referring to fig. 6, fig. 6 is a schematic cross-sectional view of the atomizer shown in fig. 1 in the direction of B-B.

In an embodiment, the atomizer 10 further includes a third capillary liquid absorption structure 19, the third capillary liquid absorption structure 19 is disposed on a portion of the inner wall of the air flow channel 13, which is close to the atomizing core 14, and the third capillary liquid absorption structure 19 is used for cooperating with the first capillary liquid absorption structure 15 to absorb the liquid loading, so as to further increase the liquid storage capacity inside the atomizer 10, further reduce the risk of liquid leakage, and facilitate improving the liquid leakage prevention effect of the atomizer 10.

Further, the third capillary wicking structure 19 is provided to the first carrier 132 of the above-described embodiment. Specifically, the third capillary wicking structures 19 are provided in the side walls of the cavities of the first carrier 132, while the first capillary wicking structures 15 are provided in the bottom of the cavities of the first carrier 132. The aerosol substrate absorbed by the third capillary wicking structure 19 will flow further towards the first capillary wicking structure 15 to be absorbed by the first capillary wicking structure 15.

It should be noted that the first capillary wicking structure, the second capillary wicking structure, and the third capillary wicking structure may be capillary grooves. As shown in fig. 3, the first capillary wicking structure 15 preferably extends in the opposite direction thereof from the second capillary wicking structure 16. That is, the first capillary wicking structure 15 extends in the longitudinal direction. Of course, the third capillary wicking structure may also extend in the longitudinal direction, and is not limited herein.

Please continue to refer to fig. 4. The second capillary wicking structure 16 includes first capillary channels 161 and second capillary channels 162. The first capillary groove 161 and the second capillary groove 162 communicate with each other and extend in different directions. By the above manner, the speed of the second capillary liquid absorption structure 16 for absorbing the aerosol substrate is improved, the effect of the second capillary liquid absorption structure 16 for absorbing the aerosol substrate is improved, the risk of liquid leakage is further reduced, and the liquid leakage prevention effect of the atomizer is improved.

In the present embodiment, for a straight liquid type atomizer, the plane defined by the extending directions of the first capillary groove 161 and the second capillary groove 162 is perpendicular to the central axis of the atomizer, and the capillary grooves of the first capillary suction structure extend in the central axis direction of the atomizer.

Optionally, the capillary grooves of the first, second and third capillary wicking structures preferably have a width of less than 1mm, so that the first, second and third capillary wicking structures have sufficient capillary wicking capability. If the width of the capillary groove is too large, the capillary absorption capacity of the capillary groove is weak and insufficient for use. Also, the design value of the capillary groove width is also dependent on the viscosity of the aerosol substrate and the structural design constraints of the atomizer. In addition, the larger the depth of the capillary groove is, the larger the liquid storage amount is, so that under the condition that the structure allows, the depth of the capillary groove is increased, the liquid storage amount of the capillary groove is increased, and the liquid leakage risk is reduced.

In summary, in the atomizer provided by the present invention, after the amount of the accumulated liquid absorbed by the first capillary liquid-absorbing structure reaches the threshold value, the accumulated liquid in the first capillary liquid-absorbing structure further enters the second capillary liquid-absorbing structure and is absorbed by the second capillary liquid-absorbing structure, that is, the amount of the accumulated liquid in the first capillary liquid-absorbing structure is increased by the first capillary liquid-absorbing structure and the second capillary liquid-absorbing structure, so that the risk of leakage of the accumulated liquid can be reduced, and the liquid leakage prevention effect of the atomizer can be further improved.

Second, the first and second capillary wicking structures of the present invention have a gap therebetween. The gas that gets into from the air inlet passes through clearance, first capillary imbibition structure in proper order and reaches the atomizing core to allow gas even mixed flow in the clearance, and evenly distributed to in the first capillary imbibition structure, and then export to the user through first capillary imbibition structure and carry the aerosol substrate after the atomizing. And, first capillary imbibition structure still plays the effect of rectification for the velocity of flow and the flow direction of the air current through first capillary imbibition structure are comparatively unanimous, thereby make the air current cover atomizing core better, optimize the air current in the atomizer and carry the aerosol matrix of atomizing core department to the gas outlet better, and then provide the aerial fog that carries aerosol matrix better for the user, are favorable to improving user experience.

Furthermore, the blocking piece is arranged in the airflow channel, and the blocking piece forms blocking between the gap and the air inlet so as to prevent the backflow atomized air from directly leaking from the air inlet to cause the problem of liquid leakage.

In addition, the air inlet channel and the gap are arranged in a staggered mode, namely the air inlet part of the atomizer and the main atomizing air channel are arranged in a staggered mode, and the problem of liquid leakage caused by the fact that atomized air flowing back from the gap directly escapes from the air inlet channel is also solved.

Furthermore, the aerosol substrate absorbed in the first capillary wicking structure is returned to the atomizing wick for re-atomization under the driving of the air flow during the user's drawing, which can improve the utilization of the aerosol substrate of the atomizer of the present invention.
