技术领域technical field

本申请实施例涉及气溶胶生成系统技术领域，尤其涉及一种雾化器及电子雾化装置。The embodiments of the present application relate to the technical field of aerosol generation systems, and in particular, to an atomizer and an electronic atomization device.

背景技术Background technique

烟制品(例如，香烟、雪茄等)在使用过程中燃烧烟草以产生烟草烟雾。人们试图通过制造在不燃烧的情况下释放化合物的产品来替代这些燃烧烟草的制品。Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning them.

此类产品的示例为加热装置，其通过加热而不是燃烧材料来释放化合物。例如，该材料可为烟草或其他非烟草产品，这些非烟草产品可包含或可不包含尼古丁。作为另一示例，存在有气溶胶提供制品，例如，所谓的电子雾化装置。这些装置通常包含液体，该液体被加热以使其发生汽化，从而产生可吸入蒸气或气溶胶。已知的电子雾化装置中采用液体泵向加热器传递液体，液体泵在非工作时仍然有少量的液体渗流向加热器，影响通过液体泵供应给加热器的液体的量的准确性。An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing articles, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize it, resulting in a breathable vapor or aerosol. In the known electronic atomization device, a liquid pump is used to transfer liquid to the heater. When the liquid pump is not working, a small amount of liquid seeps to the heater, which affects the accuracy of the amount of liquid supplied to the heater by the liquid pump.
