Description

一种净化空气的吸尘器
技术领域
本发明涉及吸尘器及空气净化技术领域，具体涉及一种净化空气的吸尘器。
背景技术
吸尘器按结构可分为立式、卧式和便携式。吸尘器的工作原理是，利用电动机带动叶片高速旋转，在密封的壳体内产生空气负压，吸取尘屑。
吸尘器主要由起尘、吸尘、滤尘三部分组成，一般包括串激整流子电动机、离心式风机、滤尘器(袋)和吸尘附件。一般吸尘器的功率为400-1000W或更高，便携式吸尘器的功率一般为250W及其以下。吸尘器能除尘，主要在于它的“头部”装有一个电动抽风机。抽风机的转轴上有风叶轮，通电后，抽风机会以每秒500圈的转速产生极强的吸力和压力，在吸力和压力的作用下，空气高速排出，而风机前端吸尘部分的空气不断地补充风机中的空气，致使吸尘器内部产生瞬时真空，和外界大气压形成负压差，在此压差的作用下，吸入含灰尘的空气。灰尘等杂物依次通过地毯或地板刷、长接管、弯管、软管、软管接头进入滤尘袋，灰尘等杂物滞留在滤尘袋内，空气经过滤片净化后，再由机体尾部排出。
吸尘器的工作原理是吸尘器电机高速旋转,从吸入口吸入空气，使尘箱产生一定的真空，灰尘通过地刷、接管、手柄、软管、主吸管进入尘箱中的滤尘袋，灰尘被留在滤尘袋内，过滤后的空气再经过一层过滤片进入电机，这层过滤片是防止尘袋破裂灰尘吸入电机的一道保护屏障，进入电机的空气经电机流出,由于电机运行中碳刷不断的磨损，因此流出吸尘器前又加了一道过滤。过滤材料越细密就可以将空气过滤得吸尘器越干净，但透气度就越差，这样影响了电机吸入的风量，降低了吸尘器效率。它的透气度是较低的，因此都做成波浪形以增加透气面积。
但现有的吸尘器过滤部件，其设计的主要考虑是过滤灰尘。但在目前的室内环境中，由于空气中富含大量气态以及微粒污染物，这些气态以及微粒污染物附着在灰尘颗粒上。当吸尘时，其从灰尘颗粒表面脱附，从而重新进入室内环境的气体，导致空气被再次污染。
发明内容
