当前,一次性气溶胶发生装置的雾化器结构中,一般是将玻纤管与雾化芯直接组装在一起。由于玻纤管的顶部与雾化器的吸嘴连接,玻纤管的底部插设于雾化芯的雾化支架的内侧,而玻纤管本身具有一定的弹性,致使玻纤管与雾化芯之间的结构稳定性较差,通常会导致雾化芯与玻纤管之间存在装配间隙,容易出现漏液现象,降低用户使用的体验感。At present, in the atomizer structure of the disposable aerosol generating device, the glass fiber tube and the atomizing core are generally directly assembled together. Because the top of the glass fiber tube is connected to the suction nozzle of the atomizer, the bottom of the glass fiber tube is inserted inside the atomization bracket of the atomizing core, and the glass fiber tube itself has a certain degree of elasticity, which makes the glass fiber tube and the atomizer The structural stability between the cores is poor, which usually leads to an assembly gap between the atomizing core and the glass fiber tube, which is prone to liquid leakage and reduces the user experience.
