Wherein the first liquid guide 11 has a first atomizing surface 111, the second liquid guide 12 has a second atomizing surface 121, a plurality of first penetrating holes are capable of delivering an atomized medium to the first atomizing surface 111, a plurality of second penetrating holes are capable of delivering an atomized medium to the second atomizing surface 121, and the atomized medium of the first atomizing surface 111 and the second atomizing surface 121 can be heated and atomized.

In the liquid guiding structure 101 of the above embodiment, since the first liquid guiding member 11 has the plurality of first penetrating holes and the second liquid guiding member 12 has the plurality of second penetrating holes, the porosity of the first liquid guiding member 11 is smaller than that of the second liquid guiding member 12, and the plurality of first penetrating holes can convey the atomized medium to the second liquid guiding member 12, so that the atomized medium can be stored in the second liquid guiding member 12 in advance through the first liquid guiding member 11. The first liquid guide 11 has a first atomization surface 111, the second liquid guide 12 has a second atomization surface 121, a plurality of first penetration holes can convey atomized media to the first atomization surface 111, a plurality of second penetration holes can convey atomized media to the second atomization surface 121, the atomized media of the first atomization surface 111 and the second atomization surface 121 can be heated and atomized, when the temperature is lower in the heating early stage, the viscosity of the atomized media is high, the flow speed of the atomized media in the first liquid guide 11 is low, and the atomized media mainly originate from the atomized media stored in the second liquid guide 12; after the later stage atomizing medium slowly heats up, the fluidity of the atomizing medium is enhanced, and the amount of the atomizing medium on the first atomizing surface 111 of the first liquid guide 11 is increased to match the amount of the atomizing medium required to be consumed at the later stage high temperature. Specifically, the first liquid guide 11 is in direct contact with the atomizing medium, and since the first liquid guide 11 has a small porosity, excessive overflow of the atomizing medium at the first liquid guide 11 can be prevented even if not used for a long period of time. The second liquid guide piece 12 is connected with the first liquid guide piece 11, and because the second liquid guide piece 12 has larger porosity, the atomized medium prestored in the second liquid guide piece 12 can keep normal permeation of the atomized medium when the temperature is lower in the heating early stage, so that the requirement of atomization in the heating early stage is met; after the temperature of the atomized medium in the first liquid guide 11 is increased in the later heating stage, the fluidity of the atomized medium is increased, and the first liquid guide 11 is provided with a first atomization surface 111, so that the exudation speed of the atomized medium on the first atomization surface 111 of the first liquid guide 11 is increased under the condition that the fluidity of the atomized medium is increased in the later heating stage, and the atomized medium can be used as a main atomization source in the later heating stage, but the heating speed is overall slowed down due to the fact that the first liquid guide 11 is far away from a heat source, the permeation speed of the atomized medium generally tends to be stable and is matched with the actual consumption speed of the atomized medium, and the atomized medium in the second liquid guide 12 is conveyed through the first liquid guide 11, so that even if the permeation of the atomized medium is increased in the later heating stage, the atomized medium conveyed into the second liquid guide 12 is not too much due to the limitation of the porosity of the first liquid guide 11, and the problem of excessive permeation and consumption of the atomized medium cannot be caused. The first liquid guide piece 11 and the second liquid guide piece 12 can realize liquid guide complementation in the earlier stage and the later stage of heating, so that atomization is uniform and full, the use experience of a user is improved, and atomized medium waste is avoided.

Thus, the liquid guiding structure 101 has a simple structure, and the liquid guiding speed of the liquid guiding structure 101 in the whole heating process is stable.

Illustratively, a host 200 (see fig. 7) of the aerosol-generating device heats the aerosol-generating substrate to generate an aerosol, which is able to enter the second nebulization channel 14 and the first nebulization channel 13 to mix with the nebulized gas nebulized by the nebulized medium to form a mixed gas for inhalation by the user. Illustratively, the aerosol is capable of heating and atomizing the atomizing medium of the second atomizing surface 121 as it flows through the second atomizing passage 14 because the aerosol carries heat and the aerosol has a temperature greater than the atomizing temperature of the atomizing medium. The aerosol can heat and atomize the atomizing medium of the first atomizing surface 111 as it flows through the first atomizing channel 13.

In some embodiments, the first plurality of penetration holes are capable of transporting the nebulized medium from inside to outside to the first nebulized surface 111 and the second plurality of penetration holes are capable of transporting the nebulized medium from inside to outside to the second nebulized surface 121. In this way, the atomized medium can be heated and atomized on the first atomization surface 111 and the second atomization surface 121, which provides a guarantee, and is beneficial to realizing stable liquid guiding of the liquid guiding structure 101 in the whole heating process.

Referring to fig. 3, in some embodiments, the first liquid guiding member 11 is formed with a first sub-channel 112 for conveying the atomized medium, the first sub-channel 112 and the first atomized channel 13 are communicated through a plurality of first penetration holes, a part of the first penetration holes can convey the atomized medium in the first sub-channel 112 to the first atomized surface 111, and another part of the first penetration holes can convey the atomized medium in the first sub-channel 112 to the second liquid guiding member 12. Through setting up first subchannel 112, first subchannel 112 can store partial atomized medium in advance, because first subchannel 112 is nearer from the heat source, atomized medium in the first subchannel 112 becomes strong in atomizing later stage mobility, ensure that the heating later stage atomized medium carries to first atomization surface 111 efficient enough, can guarantee simultaneously that the first drain piece 11 can in time carry comparatively abundant atomized medium to second drain piece 12 in the heating later stage, prevent to influence whole suction taste owing to atomized medium on the second drain piece 12 is not enough. The atomized medium in the first sub-channel 112 can be conveyed to the second liquid guide member 12 through the other part of the first penetration holes, the atomized medium flowing out of the first sub-channel 112 is conveyed to the second liquid guide member 12 through a plurality of first penetration holes, the atomized medium of the first liquid guide member 11 is effectively prevented from being conveyed to the second liquid guide member 12 too fast, too much atomized medium in the second liquid guide member 12 is caused, the problem that the atomized medium cannot be atomized in time due to too fast penetration speed of the second liquid guide member 12, and the atomized medium leaks out is avoided, and therefore the use experience of a user is improved.

Referring to fig. 3, in some embodiments, the second liquid guiding member 12 is formed with a second sub-channel 122, and another portion of the first penetrating holes can convey the atomized medium in the first sub-channel 112 to the second sub-channel 122. By providing the second sub-channel 122, a certain amount of atomizing medium can be stored in the second liquid guiding member 12 in advance, so that it is ensured that sufficient atomizing medium can be transported to the second atomizing surface 121 for atomization at the second liquid guiding member 12 in the heating stage.

In some embodiments, the first atomization channel 13 is disposed inside the first liquid guide 11, the second atomization channel 14 is disposed inside the second liquid guide 12, and the first atomization surface 111 is at least partially formed on an inner peripheral wall of the first liquid guide 11; the second atomizing surface 121 is at least partially formed on the inner peripheral wall of the second liquid guide 12. In this way, a guarantee is provided that the nebulizing medium can be nebulized inside the first liquid guide 11 and inside the second liquid guide 12.

In some embodiments, the first liquid guide 11 and the second liquid guide 12 are formed with a penetrating atomizing channel (not shown), and the plurality of first penetrating holes can convey the atomizing medium from outside to inside to the first atomizing surface 111, and the plurality of second penetrating holes can convey the atomizing medium from outside to inside to the second atomizing surface 121. Illustratively, a host 200 (see fig. 7) of the aerosol-generating device heats the aerosol-generating substrate to generate an aerosol, which can enter the nebulization channel to be mixed with the nebulized gas nebulized by the nebulized medium and then be inhaled by the user. Illustratively, the aerosol, which is heated and atomized by the first atomizing surface 111 inside the first liquid guide 11 and the second atomizing surface 121 inside the second liquid guide 12, can flow through the atomizing channel because the aerosol carries heat and has a temperature greater than the atomizing temperature of the atomizing medium.

Referring to fig. 4 and 5, in some embodiments, the first liquid guiding member 11 is provided with a first engaging portion 113, and the second liquid guiding member 12 is provided with a second engaging portion 123 that engages with the first engaging portion 113.

It will be appreciated that in other embodiments, the detent may be other shapes, such as an L-shape, etc.

In other embodiments, the first liquid guiding member 11 and the second liquid guiding member 12 may be connected by other connection methods, such as adhesive connection or magnetic connection.

In some embodiments, the porosity of the first liquid guide 11 is greater than 30% and less than or equal to 40%, and the porosity of the second liquid guide 12 is greater than or equal to 50% and less than or equal to 60%. In this way, in the heating process, it can be ensured that enough atomized medium is heated and atomized on the first atomization surface 111 of the first liquid guide 11 and the second atomization surface 121 of the second liquid guide 12 to ensure a better suction taste, and the problem of liquid leakage caused by excessive overflow of the atomized medium on the first liquid guide 11 and/or the second liquid guide 12 can be avoided.

Referring to fig. 6, in some embodiments, the liquid guiding structure 101 further includes a third liquid guiding member 15.

Thus, when the temperature is lower in the heating early stage, the viscosity of the atomized medium is high, the flow speed of the atomized medium in the first liquid guide 11 and the second liquid guide 12 is low, and the atomized medium mainly comes from the atomized medium stored in the third liquid guide 15; after the later-stage atomizing medium slowly heats up, the fluidity of the atomizing medium is enhanced, the quantity of the atomizing medium on the first atomizing surface 111 of the first liquid guide piece 11 and the quantity of the atomizing medium on the second atomizing surface 121 of the second liquid guide piece 12 are increased to some extent, the quantity of the atomizing medium consumed at the later-stage high temperature is matched, the complementation of the liquid guide in the earlier heating stage and the later heating stage is realized, the atomization is more uniform, the liquid leakage and the dry burning are effectively prevented, and the use experience of a user is improved.

At least part of the first liquid guide 11 is arranged in the filter body 102, and the atomizing medium in the storage silo 1021 can be conveyed to the second liquid guide 12 through the plurality of first permeation holes.

In the filter assembly 100 of the above embodiment, since the first liquid guiding member 11 of the liquid guiding structure 101 has the plurality of first penetrating holes and the second liquid guiding member 12 has the plurality of second penetrating holes, the porosity of the first liquid guiding member 11 is smaller than that of the second liquid guiding member 12, and the plurality of first penetrating holes can convey the atomized medium to the second liquid guiding member 12, the atomized medium can be stored in the second liquid guiding member 12 in advance through the first liquid guiding member 11.
