Abstract

本实用新型公开了一种厕所防臭装置,系安装在 楼房厕所下水口处的单向阀装置。它的壳体呈喇叭 状,单向阀通过弹簧控制打开或闭合。该装置可以阻 止下水道的臭气挥发。

Description

本发明涉及一种厕所防臭装置。尤其是安装在厕所下水口处的防臭装置。
众所周知,由现有的楼房厕所下水口处挥发出的臭气,造成了室内空气的污染。已经公开的专利申请“自动防回水控制装置”(公开号CN1069094A),该装置即解决了回水外溢,也解决了臭气挥发问题。该装置包括上、下管状及突出的浮球仓构成的壳体。装置管壁内设有凹形槽,凹形槽内装有橡胶密封圈浮球仓内壁两侧各设有一道浮球滚道凸台,呈斜坡形,浮球滚道凸台上托架着一个由橡胶或塑料构成的充气式空心浮球。该装置的不足之处是若要解决现有楼房厕所防臭问题,必须更换现有的蹲式大便器。另外,还存在充气式空心浮球一旦损坏,不易更换的问题。
本发明的目的是较容易地解决现有楼房厕所的防臭问题,以及便于维修的问题。
本发明的要点是在厕所下水口处按装一个单向阀装置。单向阀和壳体通过绞接座处的螺纹连接。单向阀打开或闭合通过弹簧控制。壳体呈喇叭状,按置在厕所下水口处。壳体和单向阀可以采用ABS、PE、PS、PVC、PP、NAS、AS及尼龙材料,采用注塑或挤压工艺制成。
该装置具有以下优点:1、价格便宜。2、按装、维修方便。3、弹簧失灵可以更换。
下面结合附图对本发明的实施例作进一步详细的描述。
图1为本发明厕所防臭器的侧视图。
图2为本发明厕所防臭器局部向视图。
从图1、图2可知该装置呈下面小,上面大的喇叭状。单向阀2和壳体1在绞接处通过螺纹连接。同时连接单向阀2和壳体的弹簧6一端固定在弹簧卡座4上,另一端固定在壳体下端的凹槽5中。
当该装置处于防臭工作状态时,单向阀2与壳体底面闭合,阻断下水口处臭气上升。当冲洗厕所时,由于水流的压力,迫使单向阀2向下打开,污物和水流通过。冲洗完毕,水流中断,即恢复防臭状态。
