Abstract

本实用新型提供一种下水道自封地漏,包括上体、下体和弹性密封皮腕,上体与下体套装在一起,上体呈盒形,其侧面设有出水口,下体的下部呈锥形并设有落水孔,弹性密封皮腕固定套装在下体上并与下体紧密贴合,上体、弹性密封皮腕与下体之间形成一个密封腔。使用时,污水流入经上体侧面的出水口进入密封腔,水流压力使弹性密封皮腕打开,污水沿落水孔排出;当没有水流时,弹性密封皮腕靠自身弹性与下体紧密贴合,实现自动密封。本实用新型结构简单,不需水封,不借助弹簧、磁铁等外力,利用水流压力自动调节弹性密封碗开闭。本实用新型具有结构简单、能够自动封堵的特点。

Description

一种下水道自封地漏
技术领域
本实用新型涉及一种用于废水排出的地漏,属于地漏技术领域。 
背景技术
地漏是连接排水管道系统与室内地面的重要接口,其性能好坏直接影响室内空气的质量。目前的地漏一般有栅格式、水封式以及自封式几类,栅格式只有排水功能,没有防臭功能;水封式极易干涸,需要经常往存水弯中补水,费时费力;自封式地漏有浮球自封式、弹簧自封式和磁铁自封式等,浮球自封式利用一个塑料球漂浮来封闭排水口,但一段时间内不补水,密封就会失效;弹簧自封式结构复杂,容易锈蚀,寿命短,容易缠绕毛发、织物,不易清理;磁铁自封式用两片磁铁的磁力吸合密封垫来密封,污水中的杂质吸附在磁铁上就会导致密封垫无法闭合,需要经常擦拭,并且磁力会逐渐消失。 
发明内容
本实用新型针对现有地漏存在的不足,提供一种结构简单、使用方便、能够自动封堵的下水道自封地漏。 
本实用新型的下水道自封地漏,采用以下技术方案: 
该地漏,包括上体、下体和弹性密封皮腕,上体与下体套装在一起,上体呈盒形,其侧面设有出水口,下体的下部呈锥形并设有落水孔,弹性密封皮腕固定套装在下体上并与下体紧密贴合,上体、弹性密封皮腕与下体之间形成一个密封腔。
使用时,污水流入经上体侧面的出水口进入密封腔,水流压力使弹性密封皮腕打开,污水沿落水孔排出;当没有水流时,弹性密封皮腕靠自身弹性与下体紧密贴合,实现自动密封。 
本实用新型结构简单,不需水封,不借助弹簧、磁铁等外力,利用水流压力自动调节弹性密封碗开闭。本实用新型具有结构简单、能够自动封堵的特点。   
附图说明
附图1是本实用新型下水道自封地漏的结构示意图。 
其中:1、上体,2、出水口,3、下体,4、弹性密封皮腕,5、落水孔,6、密封腔。 
具体实施方式
附图给出了本实用新型下水道自封地漏的结构,该地漏包括上体1、下体3和弹性密封皮腕4,上体1与下体3套装在一起,上体1为一上部开口的盒形结构,其侧面设有多个出水口2,下体3的下部呈锥形并设有落水孔5,弹性密封皮腕4固定套装在下体3上并与下体3紧密贴合,上体1、弹性密封皮腕4与下体3之间形成一个密封腔6。 
使用时,将下体固定在下水道落水口处,带有弹性密封皮腕4的上体1套装在下体3上,弹性密封皮腕4与下体3的下部自动紧密贴合。污水流入上体1,并经上体1侧面的出水口2进入密封腔6,水流压力使与下体3紧密贴合的弹性密封皮腕4打开,沿落水孔5排出。当没有水流时,弹性密封皮腕4靠自身弹性与下体3紧密贴合,实现自动密封。当弹性密封皮腕4的弹性下降与下体3贴合不紧密时,可以拿出上体1,进行更换。
