即本实施例优选技术方案的净化组件，通过滤网4以及涂在滤网4内表面并由紫外光灯6激活的光触媒涂层5，可将滤网4内部空气中的污染物吸附并同时分解和/或消除，从而使污染物不会残留在滤网4上。即本实施例优选技术方案的净化组件，可同时将滤网4内部空气中的污染物吸附并分解和/或消除，可见，本实施例优选技术方案净化组件的该种净化方法，不同于现有技术中先通过滤网吸附空气中的污染物，然后再通过负离子、光触媒或UVC消除未被滤网吸附的有机化合物、氮氧化物、细菌及病毒等污染物的方法。
根据一个优选实施方式，滤网4为圆筒型结构，如图2所示。优选的，滤网4的一端与入风口1连接，滤网4的另一端密封，并使经光触媒涂层5和滤网4净化后的空气能够从滤网4的侧面排出。如图1所示，滤网4与入风口1连接的一端具有开口，便于经入风口1进入的空气可以进入滤网4内；滤网4远离入风口1的一端密封，避免未净化的空气经滤网4远离入风口1的一端排 出。本实施例优选技术方案的滤网4为圆筒型结构，外部空气经入风口1进入滤网4内部，通过滤网4以及涂在滤网4内表面的光触媒涂层5进行净化处理，由于滤网4的另一端密封，净化后的空气只能从滤网4的侧面排出，即净化后的空气经滤网4的侧面排出至滤网4与壳体2之间的区域，然后再经出风口3排出至外部。
根据一个优选实施方式，滤网4的内侧形成为待净化空间7，滤网4的外侧形成为净化空间8，并且待净化空间7的气压高于净化空间8的气压。本实施例优选技术方案的滤网4的内侧是指涂有光触媒涂层5对的一侧，即滤网4远离壳体2的一侧；滤网4的外侧是指滤网4靠近壳体2的一侧。外部空气经入风口1进入滤网4内部后，在滤网4的内侧形成待净化空间7；空气经滤网4以及涂在滤网4内表面的光触媒涂层5的净化作用后排出，在滤网4的外侧形成净化空间。优选的，待净化空间7的气压高于净化空间8的气压，在压力的推动作用下，可使待净化空间7的空气不断通过涂有光触媒涂层5的滤网4，经净化后从滤网4的侧面排出。
根据一个优选实施方式，空气净化装置还包括风扇9，如图1所示。优选的，风扇9位于入风口1与净化组件之间，以通过风扇9的作用将外部空气引入到净化组件内。本实施例优选技术方案通过风扇9的作用，可将外部的空气不断引入到净化组件内进行净化处理。或者是空气净化装置还包括抽风机(在图中未示出)。优选的，抽风机位于净化组件与出风口3之间，以通过抽风机的作用将净化空间8中净化后的空气排出。本实施例优选技术方案通过抽风机不断将净化空间8中净化后的空气抽出，从而可促使外部待净化空气不断从入风口1进入净化组件内。即本实施例优选技术方案可通过风扇主动向净化组件内送入待净化空气，也可以通过抽风机被动向净化组件内送入待净化空气。本实施例优选技术方案设置于出风口3用于排出净化空间8中空气的装置不限于抽风机，也可以是风扇，其原理类似于现有技术的抽油烟机。
根据一个优选实施方式，空气净化装置还包括束风管10，如图1所示。束风管10的一端与风扇9连接，束风管10的另一端与净化组件连接，以通过束 风管10的作用将经风扇9引入的空气导入净化组件内。或者是束风管10的一端与入风口1连接，束风管10的另一端与净化组件连接，以通过束风管10的作用将经入风口1的空气导入净化组件内。
优选的，束风管10与风扇9连接的一端的尺寸与风扇9的尺寸相当，束风管10与净化组件连接的一端的尺寸与净化组件的尺寸相当。或者是束风管10与入风口1连接的一端的尺寸与入风口1的尺寸相当，束风管10与净化组件连接的一端的尺寸与净化组件的尺寸相当。
如图1所示，束风管10为喇叭形。本实施例优选技术方案，束风管10与风扇9连接的一端的尺寸与风扇9的尺寸相当，与滤网4连接的一端的尺寸与滤网4的尺寸相当，使得风扇9引入的空气可全部导入滤网4内部，以便可以对引入净化装置内部的全部空气进行净化。
本实施例的另一方面还提供了一种空气净化方法。本实施例的空气净化方法是使用本实施例任一技术方案的空气净化装置来完成的。
优选的，本实施例的空气净化方法包括如下步骤：
S1：启动空气净化装置，引入待净化空气。优选的，外部待净化空气通过入风口1、风扇9和束风管10引入滤网4内部。
S2：分解和/或消除待净化空气中的污染物。优选的，进入滤网4内部的待净化空气，穿过内表面涂有光触媒涂层5的滤网4，待净化空气中的污染物被吸附在滤网4上并同时被光触媒涂层5分解和/或消除。
S3：排出净化后的空气。优选的，经光触媒涂层5和滤网4净化的空气经滤网4的侧面排出至净化空间8，净化空间8内的空气经出风口3排出至空气净化装置外部。
本实施例的净化方法，通过光触媒涂层5和滤网4同时将滤网4内部空气中的污染物吸附并分解和/或消除，使得污染物不会残留在滤网4上，从而不会滋生细菌，也不会对环境造成二次污染，解决了现有技术的净化设备和/或净化方法造成部分污染物残留在净化设备的滤网上，不仅滋生细菌，也可能对环境 造成二次污染的技术问题。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
