The reservoir 232 is for storing a liquid aerosol-generating substrate 232a, which may in particular be a cylindrical container fitted with a housing 260, sealed at one end and having an opening at the other end, the sealed end of the reservoir 232 being located to one side of the mouthpiece assembly 210. A gap is provided between the reservoir 232 and the housing 260, which gap forms part of the gas passage 238 of the overall gas passage. Specifically, the air passage 238 may be one or more through grooves formed on the outer periphery of the cylindrical storage tank 232, or the storage tank 232 may be integrally recessed inward to form the air passage 238 with the housing 260. The air passage 238 may be straight, or may be curved or inclined, and the present invention is not limited thereto.

The oil seal cover 234 and the oil-permeable member 236 are disposed at one end of the storage tank 232 having an opening, and the oil seal cover 234 and the oil-permeable member 236 are sequentially disposed from the inside to the outside of the storage tank 232.

In other embodiments, as shown in fig. 8, the oil cap 234 may be configured in a pattern such that a portion thereof is inserted into the tank 232 and another portion thereof is exposed to the port of the tank 232. As another preferred embodiment, the oil seal cover 234 further has a cavity for accommodating the oil-permeable member 236. Preferably, the oil seal cover 234 is in interference fit with the storage tank 232, and the outer diameter of the oil seal cover 234 exposed out of the port of the storage tank 232 is consistent with the outer diameter of the storage tank 232.

Specifically, the oil seal cover 234 may be made of silicone, rigid plastic or metal, and the oil-permeable member 236 may be made of a fiber bundle material or other materials with liquid storage capacity.

Referring to fig. 9, a schematic view of a tank assembly 330 according to another embodiment of the present invention is shown, in which the tank assembly 330 is different from the tank assembly 230 of the previous embodiment only in that the tank 332 has openings at both ends, and the port of the tank 332 near the nozzle assembly 210 is provided with an upper cover 332a for sealing. The upper cover 332a is provided in a form to be fitted to the storage tank 332. Specifically, as shown in fig. 9, the upper cover 332a may be provided inside the tank 332, or may be provided in a pattern in which a portion is inserted into the tank 332 and another portion is exposed out of the port of the tank 332. Preferably, the upper cover 332a is in interference fit with the storage tank 332, and the outer diameter of the outer portion of the upper cover 332a exposed out of the port of the storage tank 332 is identical to the outer diameter of the storage tank 332. The material of the upper cover 332a may be silicone. A protruding catch may be further provided in the tank 332 for catching the upper cover 332 a.

An advantage of having an open reservoir at both ends and sealed with a silicone top cap as opposed to an open reservoir at one end is that the open reservoir at one end must be filled with liquid aerosol-generating substrate before other components can be placed, and therefore the assembly process is complicated, and the liquid aerosol-generating substrate is prone to deterioration, leaking oil or evaporation after filling. And the liquid aerosol generating substrate can be injected by puncturing the silica gel upper cover through the injector after other components are installed by adopting silica gel upper cover sealing, and the sealing effect can still be recovered after the upper cover is punctured due to the characteristics of the silica gel. Therefore, the mode that the openings at the two ends of the storage tank are sealed by the silica gel upper cover not only enables the assembly process to be simpler and the cost to be lower, but also prevents oil leakage and volatilization by injecting the liquid aerosol generating substrate, and has the effect of prolonging the service cycle of the product.

In other embodiments, the air passages 238 through both ends of the reservoir 232 may be provided not outside the reservoir 232 but inside the reservoir 232 to form a hollow passage.

Preferably, the reservoir 232, the housing 260 and the wrapper 270 all have see-through regions so that a user can see the consumption of the liquid aerosol-generating substrate 232 a.
