Description

PM2.5换气扇
技术领域
本发明涉及一种换气扇，特别是一种利用水帘吸收PM2.5的PM2.5换气扇。
背景技术
目前，空气污染日益严重，不少地方的空气PM2.5指数经常处于非良好的状态，一些地方达到中度污染，有些室内场所甚至达到重度污染，影响人们了的身体健康，一种室内使用的PM2.5换气扇已经成为人们净化室内空气的需要。
发明内容
本发明的目的是克服现有技术的不足，提供一种PM2.5换气扇，用于吸收室内的灰尘以及PM2.5，净化室内的空气。
本发明所采用的技术方案是：PM2.5换气扇包括有过滤装置、外壳以及控制器；过滤装置包括有双向排气扇、水泵、水帘喷头以及百叶窗，双向排气扇包括有电机以及风叶，外壳设有进风口、出风口以及水箱，电机的机座与外壳固定连接，电机的前轴与风叶固定连接，电机的后轴与单向传动联轴器连接，单向传动联轴器与水泵的转轴固定连接，水泵的外壳座与外壳固定连接；电机正转时，带动水泵正转，电机反转时，由于单向传动联轴器只有单向传动的功能，水泵不转动；百叶窗位于出风口，百叶窗与外壳连接，水帘喷头位于百叶窗的上部，水箱位于百叶窗的下部，水帘喷头与水泵的出水口连接，水泵的入水口与外壳的水箱连接；水箱设有过滤水，用于产生过滤水帘，百叶窗设有过滤水帘，过滤水帘由水帘喷头喷出，水帘喷头喷出的过滤水帘经百叶窗流入水箱；水箱设有进水电磁阀以及水位开关，进水电磁阀与自来水管连接，用于向水箱自动补充水；控制器设有控制线与电机、进水电磁阀以及水位开关连接；水箱设有水过滤器以及消毒液注入装置，水过滤器用于净化过滤水，消毒液注入装置用于向过滤水注入消毒液。
PM2.5换气扇的工作原理是：将PM2.5换气扇安装于房间的墙壁孔上，并使外壳的出风口位于室内一侧，进风口位于室外一侧，利用控制器控制其过滤装置直接把室内的空气排出到室外，然后，将室外的新鲜空气通过其过滤装置过滤后引入室内，如此不断循环；由室外引入新鲜空气时，控制器控制电机正转，电机带动风叶以及水泵正转，水箱的过滤水被水泵抽至水帘喷头，由水帘喷头喷到百叶窗，过滤水由百叶窗的上部流向下部，过滤水在百叶窗形成一个过滤水帘；同时，风叶正转，将室外的新鲜空气由进风口抽入，新鲜空气经过百叶窗的过滤水帘过滤后由出风口进入室内，利用过滤水帘吸收新鲜空气中的灰尘以及PM2.5；引入新鲜空气时间到，控制器控制电机反转，单向传动联轴器反转不起传动作用，水泵不转动，电机只带动风叶反转，室内的空气由出风口进入，经百叶窗以及进风口排到室外，把室内的空气排到室外；如此不断循环。
本发明的有益效果是：PM2.5换气扇设有过滤装置，过滤装置设有双向排气扇、百叶窗、水泵以及水帘喷头，百叶窗设有过滤水帘，利用控制器控制双向排气扇的电机反转，把室内的空气排出到室外；利用控制器控制双向排气扇的电机正转，把室外的新鲜空气抽入室内，新鲜空气进入室内时先经过百叶窗的过滤水帘过滤，利用过滤水帘吸收室外空气的灰尘以及PM2.5，从而达到了更换以及净化室内空气的目的；同时，于过滤水帘加入消毒液，使过滤水帘具有消毒新鲜空气的功能。
