下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.
现有的雾化组件是通过在雾化芯的表面设置凹槽结构与储油组件的储液腔相连以实现雾化液的传导。然而在雾化芯的表面设置凹槽结构一方面会降低雾化组件的结构强度,缩短其使用寿命;二是凹槽结构不利于雾化液浸润,使雾化液在雾化组件中分布不均;三是在烧制过程中,由于陶瓷烧结需要使用埋烧粉进行掩埋,埋烧粉容易进入雾化组件的凹槽结构中,影响雾化组件的正常使用。为提高雾化组件的结构强度和导油速度,提高雾化组件生产的合格率,本申请实施例提供了一种雾化组件,该雾化组件不仅解决了由于设置凹槽结构使得雾化芯的结构强度降低的问题,同时也很好地减少了雾化芯漏油的情况,具有很好的雾化效果。The existing atomizing assembly is connected with the liquid storage cavity of the oil storage assembly by arranging a groove structure on the surface of the atomizing core to realize the conduction of the atomized liquid. However, setting the groove structure on the surface of the atomizing core will, on the one hand, reduce the structural strength of the atomizing component and shorten its service life; on the other hand, the groove structure is not conducive to the infiltration of the atomizing liquid, so that the distribution of the atomizing liquid in the atomizing component is not good. The third is that during the firing process, because the ceramic sintering needs to be buried with buried sintered powder, the buried sintered powder is easy to enter the groove structure of the atomizing component, which affects the normal use of the atomizing component. In order to improve the structural strength and oil guiding speed of the atomizing assembly, and improve the production pass rate of the atomizing assembly, the embodiment of the present application provides an atomizing assembly, which not only solves the problem that the atomizing core is caused by the setting of the groove structure. At the same time, it also reduces the oil leakage of the atomizing core, and has a good atomization effect.
