Description

一种分离器及具有该分离器的吸尘器 技术领域
本实用新型涉及吸尘器技术领域，尤其涉及一种分离器及具有该分离器的吸尘器。
背景技术
分离器，是用于气固体系或者液固体系分离的一种设备。工作原理为靠气流切向引入造成的旋转运动，使具有较大惯性离心力的固体颗粒或液滴甩向外壁面分开。分离器应用在吸尘器中，作用是在空气从吸尘器中向外排出之前，将被吸入的空气中的可能依然含有的残余的污染物/灰尘留下。分离器通常不可转动地安装在吸尘器的电机的电机轴上，并以高速进行旋转。
现有的分离器一般包括顶板和底板，顶板和底板均呈圆形，顶板的直径大于底板的直径，这种分离器吸风力较小，对于吸入的固体颗粒或液滴的速度改变较小，在分离器的初始速度较低的情况下，容易吸进固体颗粒或液滴，导致垃圾分离效果较差，而且吸入的固体颗粒或液滴会粘附于过滤元件上，影响过滤元件的使用寿命。

为了达到上述目的，本实用新型采用的技术方案如下：
本实用新型一方面提供了一种分离器，包括顶板、底板和多个格栅条，所述顶板和所述底板均呈圆形，所述顶板的直径小于所述底板的直径，
所述分离器具有电机连接部，所述电机连接部的中心与所述分离器的旋转中心重合；
