Electronic cigarettes are also known as virtual cigarettes and electronic atomizers. As an alternative cigarette, e-cigarettes are used to quit smoking. E-cigarettes have a similar appearance and taste to cigarettes, but generally do not contain other harmful components such as tar, aerosols, etc. in cigarettes.

Electronic cigarettes are mainly composed of an atomizer and a power supply unit. The atomizer is used as the core device for generating atomized gas from electronic cigarettes. At present, electronic aerosolizers on the market generally include oil storage devices, oil guiding devices, and heat generating devices. The oil storage devices are generally glass or other containers for storage. The liquid smoke and the oil guiding device introduce the smoke liquid in the oil storage container onto the heat generator, and the heat generating device generates heat to atomize the smoke liquid. The liquid storage device in such an atomizer stores a liquid that is easy to flow and needs to be sealed and stored.

In such an atomizer, there are several problems due to the use of a container for storing smoke liquid:

1. The structure is complicated. Since the container in the atomizer stores the easily flowing smoke liquid, the atomizer device needs to ensure the airtightness to ensure that the liquid does not leak out of the atomizer.

2. During the use, transportation and storage of the product, the atomizer is prone to liquid leakage due to changes in internal and external air pressure, which affects the function and use of the product.

Embodiment 1, this embodiment is an electronic cigarette in which a liquid smoke is stored in a liquid storage device 100 having a novel structure. As shown in FIG. 3 and FIG. 4, the liquid storage device 100 of the novel structure is as shown in FIG. Figure 1 and Figure 2. The liquid storage device 100 of the novel structure stores the liquid smoke by using the microporous material. In the embodiment, the volume of the micropore voids in the microporous material used for the liquid storage device 100 accounts for 30-60% of the volume of the entire microporous material. In practice, the volume of the micropore voids accounts for 40% of the volume of the entire microporous material in practice. Of course, 50% or the like can also be selected, and different volume ratios can be used in practice depending on the liquid smoke.

In this embodiment, as the liquid storage device 100 in the electronic cigarette, it is considered that the electronic cigarette is generally cylindrical.
