【技术实现步骤摘要】
一种空气清新装置
本技术属于室内或车内空气清新领域,具体的说涉及一种空气清新装置。
技术介绍
空气清新装置是指针对室内或车内的各种环境问题提供降尘除霾、祛除有害装修残留以及异味等整体解决方案,以提高改善生活、办公条件,增进身心健康。车内环境污染物和污染来源主要包括颗粒物、油漆残留、二手烟等。室内如厕所内的异味,常用的消除方式有两种:一是加装抽气装置,通过改善通风条件促进厕所内的空气与外界空气交换,使异味快速转淡;二是设置空气清新装置,通过空气清新剂的芳香气味,中和消除或掩盖异味,使如厕者嗅觉较为舒适。目前的空气清新装置,在室内用的,体积大,笨重,移动不方便,在车内用的,需要插电,车熄火后,没法供电,车内异味的产生主要是熄火后车体在阳光下爆晒后产生的,断电后不能发挥净化车内异味的功能。在室内或在汽车内,人们常用释放香气的装置,把贮存于该装置之内的由香原料配制成的香精释放到空气中,使该处的空气环境中产生香气,从而遮盖或冲淡原来空气中可能存在的不良气味,达到空气清新的效果。现有技术中的空气清新装置,在使用中不能根据周围环境的状况调节透气孔的开度和数量,而且也不能根据环境状况调节空气清新剂的散发速度。
技术实现思路
针对现有技术存在的上述问题,本技术提供一种空气清新装置,能够根据周围环境的状况调节透气孔的开度和数量,调节空气清新剂的散发速度。本技术解决其技术问题采用的方案为:专利技术一种空气清新装置,包括外筒和内筒,外筒和内筒的下端均密封,内筒置于外筒内,在内筒中放入清新剂,内筒上开设透气孔,外筒上开设透气窗,其特征在于,内筒的上端开口,内筒的顶端高于外筒顶端,内筒上 ...
【技术保护点】
1.一种空气清新装置,包括外筒和内筒,外筒和内筒的下端均密封,内筒置于外筒内,在内筒中放入清新剂,内筒上开设透气孔,外筒上开设透气窗,其特征在于,内筒的上端开口,内筒的顶端高于外筒顶端,内筒上端螺纹连接内筒盖,内筒壁上具有透气孔的区域的宽度小于内筒圆周的一半,所述内筒能围绕中心轴转动;所述外筒透气窗部位设有能沿着外筒壁滑动的遮挡片,遮挡片的数量为三个,遮挡片沿透气窗的长度方向设置,每一个遮挡片能独立动作;所述内筒密封端中心部位有凹口,所述外筒密封端中心部位有凸台,所述凹口和所述凸台相连接;所述内筒盖内侧设置风扇,内筒盖内放置电池,风扇通过导线与电池相连,内筒盖上设置电源开关,电源开关与导线相连。
