[0003] 一般而言， 粒径 2. 5微米至 10微米的粗颗粒物主要来自道路扬尘等； 2. 5 微米以下的细颗粒物 （PM2. 5 ) 则主要为日常发电、 工业生产、 汽车尾气排 放等过程中经过燃烧而排放的残留物， 大多含有重金属等有毒物质。
实用新型内容
[0004] 为克服上述缺陷本发明要解决的技术问题是设计一种空气净化器，功能 齐全， 能用于过滤细颗粒物， 保证空气湿度， 改善空气质量。
[0005] 解决技术问题所采用的技术方案为： 设计一种空气净化器， 包括机壳， 机壳设有定时报警器，所述机壳支撑着进气口与排气口，所述进气口与排气口之 间连接有空气流道， 所述空气流道中设有气泵、 风扇、 预滤器、 过滤膜以及加湿 单元、 芳香单元、 杀菌装置， 风扇生成流过空气流道的动力气流， 加湿单元使从 储箱供给来的水汽化来提高室内空气的湿度，芳香单元使储箱存储的芳香剂随气 流挥发而出， 杀菌装置对通过气流进行灭菌， 所述过滤膜的孔径小于 2. 5微米， 所述加湿单元包括所述储箱和加湿元件，所述储箱用于对水进行贮存，所述加湿 元件包括对从储箱供给来的水进行吸取的吸水构件，加湿单元使被吸取至吸水构 件的水汽化而进行加湿， 加湿元件呈圆盘形状， 并能以转轴 为中心进行旋转， 所述储箱设有进水管和出水管， 并相应的设置进水阀和出水阀，所述加湿单元包 括一空腔， 空气流道经过该空腔的开口，所述加湿单元按照空气流道的方向置于 过滤膜之后且杀菌装置之前， 所述杀菌装置为紫外线杀菌装置或臭氧杀菌装置， 所述预滤器为活性炭纤维、竹炭纤维或矿物质材料， 所述过滤膜为超滤膜、渗透 或反渗透膜， 所述过滤膜为孔径 1微米的微滤膜。
[0006] 实用新型效果： 功能齐全， 气味芳香， 能够定时报警， 保证空气湿度， 改善空气质量。在本实用新型技术方案的空气净化器中， 能在稳定的状态下设置 贮存有水的箱， 加湿单元位于机器的上部， 因此容易进行加湿单元的维修， 能使 空气容易朝吸水构件流动。

具体实施;^
[0012] 以下，参照附图对本实用新型的实施方式进行说明。以下实施方式是 本 实用新型的具体例子， 并不限定本实用新型的技术范围。
[0013] 该具有加湿功能的空气净化器， 包括机壳， 机壳设有定时报警器， 所述 机壳支撑着进气口与排气口，所述进气口与排气口之间连接有空气流道，所述空 气流道中设有气泵 1、风扇 2、预滤器 3、过滤膜 4以及加湿单元 5、芳香单元 6、 杀菌装置 7， 风扇 2生成流过空气流道的动力气流， 加湿单元 5使从储箱 8供给 来的水汽化来提高室内空气的湿度，芳香单元 6使储箱 8存储的芳香剂随气流挥 发而出， 杀菌装置 7对通过气流进行灭菌， 所述过滤膜的孔径小于 2. 5微米， 所 述加湿单元 5包括所述储箱 8和加湿元件，所述储箱用于对水进行贮存，所述加 湿元件包括对从储箱 8供给来的水进行吸取的吸水构件 9， 加湿单元使被吸取至 吸水构件的水汽化而进行加湿，加湿元件呈圆盘形状， 并能以转轴为中心进行旋 转， 所述储箱 8设有进水管 10和出水管 11， 并相应的设置进水阀和出水阀， 所 述加湿单元 5包括一空腔， 空气流道经过该空腔的开口，所述加湿单元 5按照空 气流道的方向置于过滤膜之后且杀菌装置之前，所述杀菌装置 7为紫外线杀菌装 置或臭氧杀菌装置， 所述预滤器 3为活性炭纤维、竹炭纤维或矿物质材料， 所述 过滤膜 4为超滤膜、渗透或反渗透膜， 所述过滤膜 4为孔径 1微米的微滤膜。所 述定时报警器 12与总控电路线连接并设有开关 13， 通过控制面板可以预定开机 时长， 当连续开机时间达到预定的时间 （比如 4小时） ， 定时报警器 12发出警 报，一操作者可以选择关闭开关 13， 也可以选择整机断电， 防止设备长时间疲劳 运行。
[0014] 空气净化器具有加湿功能和空气净化功能。用户能仅选择空气净化功能， 但在选择加湿功能时， 空气净化功能也伴随着起作用。经过滤膜 4过滤后的空气 已达到国家空气标准，然而考虑到医院或学校地区空气环境复杂（空气中细菌含 量较高） ， 因此， 在本净化器出气以前设置杀菌装置一套（紫外光消毒或臭氧消 毒） 以进一步提高出气的空气质量。
[0015] 长方体形状的机壳，所述机壳支撑着进气口与排气口，所述进气口与排 气口之间连接有空气流道， 所述空气流道中依次连接设有气泵 1、 风扇 2、 预滤 器 3、 过滤膜 4以及加湿单元 5、 芳香单元 6、 杀菌装置 7， 以上各部件均架设有 支撑框架。
[0016] 使用时， 空气在气泵 1的作用下沿空气流道流动， 依次通过气泵 1、 风 扇 2、 预滤器 3、 过滤膜 4以及加湿单元 5、 芳香单元 6、 杀菌装置 7， 可有效过 滤 PM2. 5颗粒物等有害物， 提高了空气质量。 [0017] 加湿元件位于上方，加湿元件能从设于主体壳体的四个侧面中的一个侧 面的侧方门进行装拆， 因此， 容易进行维修作业。
[0018] 风扇 2是能改变风量的多叶片式风扇，通过叶片旋转， 空气沿着转轴方 向被吸入， 并从叶片朝离心方向吹出。
[0019] 预滤器 3是壁薄且柔软的树脂制的网，将空气中含有的粒子较大的尘埃 等去除，能从设于主体壳体的四个侧面中的一个侧面的未图示的开闭门加以取出。
[0020] 吸水构件 9成形为环状； 其驱动机构使吸水构件 9朝规定方向回旋。吸 水构件 9由兼具吸水性和通气性的材料构成。与吸水构件 9的下部浸渍在储箱 8 的水中。
[0021] 储箱 8可由进水管 10补充水量，也可从出水管 11排放久存的低质量的 水， 正常使用状态进水阀和出水阀都关闭。
[0022] 当在空气净化器的电源接通的状态下启动加湿功能时，通过驱动而使吸 水构件 9回旋。 吸水构件 9的下部浸渍在 9水中， 因此， 通过吸水构件 9回旋 而能整体高效地吸水。 此外， 与空气净化动作时相同地， 形成由风扇 2从吸入 口吸入并从吹出口吹出的气流。 因此， 空气在流过吸水构件 9时， 促进被吸取至 吸水构件 9的水的汽化， 从而形成加湿空气。 该加湿空气沿着风道流动， 并被从 设于主体壳体的上表面前方的吹出口吹出。
[0023] 需要指出的是， 上述实施方式仅是本实用新型优选的实施例，对于本技 术领域的普通技术人员来说，在符合本实用新型工作原理的前提下，任何等同或 相似的替换均落入本实用新型的保护范围。
