The liquid-guiding and heat-generating structure 100 mainly includes an aerosol distribution member 10, a heat-generating member 20 and a liquid-absorbing member 30.

The aerosol dispensing member 10 has a first surface 11 and a second surface 12 opposite the first surface 11, and has a plurality of aerosol dispensing through holes 13 passing through the first surface 11 and the second surface 12; that is, the plurality of aerosol dispensing through holes 13 extend through the aerosol dispensing member 10 from the first surface 11 to the second surface 12. The heat generating member 20 is disposed adjacent to the first surface 11 and is configured to generate heat when energized; for example, the heat generating member 20 may be disposed in contact with or in close contact with the first surface 11, or the heat generating member 20 may be disposed on a side close to the first surface 11 with a certain distance from the first surface 11. The liquid absorbing member 30 is provided on the heat generating member 20, and serves to absorb liquid and to deliver the absorbed liquid to the vicinity of the heat generating member 20. The absorbent member 30 can have good liquid-wicking properties and can provide liquid-absorbing capabilities by, for example, allowing liquid to be uniformly distributed in the pores of the absorbent member 30 by capillary action; further, since the liquid in the liquid absorbing member 30 tends to be uniformly distributed, when the liquid in the portion of the liquid absorbing member 30 close to the heat generating member 20 is consumed by atomization, the liquid in the other portion of the liquid absorbing member 30 can be transported toward the vicinity of the heat generating member 20. The liquid may be a heat-nebulizable liquid such as tobacco tar, a medicinal liquid, or the like.

In this embodiment, the liquid guiding and heating structure 100 adopts the aerosol distribution member 10, the heating member 20 and the liquid absorbing member 30 which are sequentially arranged, and the aerosol distribution member 10 is provided with the plurality of aerosol distribution through holes 13, so that when the heating member 20 is powered on, the liquid delivered by the liquid absorbing member 30 is heated and atomized, and then the aerosol is emitted from the aerosol distribution through holes 13 in a controlled manner, thereby the atomized aerosol particles are uniform and fine.

In some embodiments, the aerosol dispensing member 10 may be a dense ceramic body and the aerosol dispensing through holes 13 are through holes perpendicular to the second surface 12. The dense ceramic body can be made of materials such as silicon carbide, aluminum nitride or aluminum oxide. Due to the dense ceramic material, the aerosol dispensing member 10 needs to be provided with through holes for the penetration of the aerosol, while the dense ceramic body does not leak gas or liquid except for these through holes. These gas mist distribution through holes 13 may be formed by mechanical drilling, laser drilling, or the like, or may be integrally molded or 3D printed with the gas mist distribution member 10. In addition, the wicking member 30 can be a multi-gap body having a plurality of liquid delivery gaps therein. For example, the liquid absorbing member 30 can be made of porous ceramic or fiberglass material, so that the liquid can be absorbed and transported by the capillary phenomenon generated by the internal pore structure of the porous ceramic or fiberglass material.

In some embodiments, the aerosol dispensing member 10 may be a zirconia sheet, such as a high density zirconia sheet; the aerosol dispensing through-hole 13 is a through-hole perpendicular to the second surface 12. The zirconia belongs to a compact ceramic material, and in the embodiment, the aerosol distribution member 10 is made of flaky zirconia; similarly, the aerosol dispensing through holes 13 may be formed by mechanical drilling, laser drilling, etc., or may be integrally molded or 3D printed with the aerosol dispensing member 10. Additionally, the absorbent member 30 can be absorbent cotton; for example, the absorbent member 30 may be a sheet of cotton or cotton cloth or the like, which has good liquid-wicking properties and allows liquid to be uniformly distributed in the pores of the absorbent member 30 by capillary action. By adopting the combination of the liquid absorption cotton and the zirconia sheets, the problems of poor taste, easy powder falling and great harm to human health caused by only adopting the ceramic core can be effectively solved, and the problems of large atomized particles, easy oil leakage and easy core pasting caused by only adopting the cotton core can also be effectively solved.

Since the second surface 12 of the aerosol dispensing member 10 is exposed through the first opening 52, after the heat generating member 20 is energized to heat and atomize the liquid delivered by the liquid absorbing member 30, the generated aerosol can be emitted from the aerosol dispensing through holes 13 through the first opening 52 for further delivery to the user for inhalation. In addition, the containing shell 50 is adopted to contain the aerosol distribution part 10, the heating part 20, the liquid absorbing part 30 and the pressing plate 40, so that the structure is simple and compact, one end of the cylindrical containing shell 50 is set as a liquid inlet end, the other end of the cylindrical containing shell is set as an atomizing end, the air channel is separated from the liquid to be atomized, and the atomized aerosol is carried thoroughly; on the other hand, the sheet heating element 20 is isolated from the liquid by the liquid absorbing element 30, so that the heat diffusion is small and the heat utilization rate is high.

By providing the first stopping portion 53 and the second stopping portion 54, the assembly of the aerosol dispensing member 10, the heat generating member 20, the liquid absorbing member 30 and the pressing plate 40 is further facilitated.

In a further embodiment, as shown in fig. 2, the receiving cavity 51 may include a first space 55 and a second space 56. Wherein the first space 55 can be used for accommodating the aerosol dispensing member 10, the heat generating member 20, the liquid absorbing member 30 and the pressing plate 40, and the second space 56 can be used for containing liquid. In other words, the part of the housing chamber 51 that houses the aerosol dispensing member 10, the heat generating member 20, the liquid absorbing member 30, and the pressing plate 40 is the first space 55, and the part other than the first space 55 is the second space 56. When the receiving chamber 51 has the second space 56, more liquid can be stored, so that the liquid in the second space 56 can be replenished to the liquid absorbing member 30 when the liquid absorbed in the liquid absorbing member 30 is consumed.

In some embodiments, the aperture of the aerosol dispensing through-hole 13 may be any value in the range of 5 μm to 100 μm, for example, may be 5 μm, 5.5 μm, 6 μm, 10 μm, 15 μm, 30 μm, 50 μm, 60 μm, 90 μm, 100 μm, and the like; the apertures of the plurality of aerosol dispensing through holes 13 may be the same or slightly different. In addition, the plurality of aerosol distribution through holes 13 may be evenly distributed, for example, may be distributed in a matrix form.
