Specifically, the planar shape of the groove 312 taken along the first direction is the same as the planar shape of the suction protrusion 311 taken along the first direction, the suction protrusion 311 is partially inserted into the groove 312, and the other portion of the suction protrusion 311 protrudes to the outside of the groove 312. Thus, on one hand, the liquid absorption protrusion 311 is inserted into the groove 312, so that the fixing effect of the groove 312 on the liquid absorption protrusion 311 is realized, and on the other hand, as the planar shape of the groove 312 cut along the first direction is the same as the planar shape of the liquid absorption protrusion 311 cut along the first direction, the outer surface of the part of the liquid absorption protrusion 311 inserted into the groove 312 is in contact with the groove wall of the groove 312, so that the transmission resistance of the aerosol forming substrate between the liquid absorption protrusion 311 and the liquid absorbing piece 31 can be reduced, and the aerosol forming substrate can be smoothly transmitted to the liquid absorbing piece 31 from the liquid absorption protrusion 311. In this embodiment, both the groove bottom wall and the groove side wall of the concave groove 312 are sufficiently in contact with the portion of the liquid suction protrusion 311 inserted into the concave groove 312.
In a specific embodiment, the porosity of the liquid absorbing protrusion 311 is different from the porosity of the liquid absorbing member 31, and the porosity of the liquid absorbing protrusion 311 is greater than the porosity of the liquid absorbing member 31, such that the liquid guiding capacity of the liquid absorbing protrusion 311 is greater than the liquid guiding capacity of the liquid absorbing member 31. In the actual use process, because the liquid absorbing protrusion 311 partially extends to the outside of the groove 312, the liquid absorbing area is increased, and because the liquid guiding capacity of the liquid absorbing protrusion 311 is greater than that of the liquid absorbing member 31, the mass of the aerosol-forming substrate absorbed by the liquid absorbing protrusion 311 with the same unit area in a unit time is greater than that absorbed by the liquid absorbing member 31 with the same unit area, by providing the groove 312, the contact area of the liquid absorbing protrusion 311 conducting the aerosol-forming substrate to the liquid absorbing member 31 is increased, that is, in the present embodiment, the contact area between the liquid absorbing protrusion 311 and the liquid absorbing member 31 is the groove wall area of the groove 312, the "groove wall" includes a groove bottom wall and a groove side wall, while in the first embodiment, the contact area between the liquid absorbing protrusion 311 and the liquid absorbing member 31 is only the plane area of the liquid absorbing protrusion 311 cut along the first direction, that is, in the first embodiment, the contact area between the liquid absorbing protrusion 311 and the liquid absorbing member 31 is equal to the The contact area of the groove bottom wall of the groove 312, the contact area between the liquid absorbing protrusion 311 and the liquid absorbing member 31 in the first embodiment is obviously smaller than the contact area between the liquid absorbing protrusion 311 and the liquid absorbing member 31 in the present embodiment. Thus, in this embodiment, the liquid-absorbing protrusion 311 can transmit the liquid-absorbing member 31 with a larger contact area while absorbing more aerosol-forming substrates, and the aerosol-forming substrates absorbed by the liquid-absorbing protrusion 311 can be efficiently transmitted to the liquid-absorbing member 31, thereby improving the liquid-guiding efficiency of the aerosol-forming substrates.

Thus, the mass of the aerosol-forming substrate absorbed by the part of the liquid absorption protrusion 311 extending out of the groove 312 in unit time is less than or equal to the mass of the aerosol-forming substrate conducted to the liquid absorption member 31 by the part of the liquid absorption protrusion 311 inserted into the groove 312 in unit time, so that the liquid absorption member 31 can completely absorb the aerosol-forming substrate on the liquid absorption protrusion 311, and the aerosol-forming substrate can be stably conducted with high efficiency. In a specific embodiment, L is 1.11mm and H is 1 mm.

In a specific embodiment, L is 1.11mm and h is 1.9 mm.
