TECHNICAL FIELDEmbodiments of this application relate to the technical field of electronic vaporization devices, and in particular, to a vaporizer and an electronic vaporization device.
BACKGROUNDTobacco products (such as cigarettes, cigars, and the like) burn tobacco during use to produce tobacco smoke. Attempts are made to replace these tobacco-burning products by manufacturing products that release compounds without burning tobacco.
An example of this type of products is a heating device that releases compounds by heating rather than burning materials. For example, the materials may be tobacco or other non-tobacco products, where the non-tobacco products may or may not include nicotine. As another example, there are aerosol-providing products, for example, electronic vaporization devices. These devices usually contain vaporizable liquid, and the liquid is heated to be vaporized, so as to generate an inhalable aerosol.
For the known electronic vaporization device, the liquid substrate is stored in and provided from the liquid storage chamber, and the liquid substrate is sucked by the liquid guide element and transferred to the heating element to be heated and vaporized. With the consumption of the liquid, the negative pressure in the liquid storage chamber gradually increases, so that the liquid substrate can hardly be sucked and transferred by the liquid guide element.
