Background
The floor drain is a connector for connecting a building sewer pipeline system and indoor ground, and is a necessary facility for places such as modern family toilets, bathrooms, kitchens, balconies and the like. The floor drain has three core functions, wherein the first core function is to discharge water flow on the ground of the toilet, the bathroom, the kitchen and the balcony into a sewer pipeline system; the second core function is to prevent the smell from returning to the sewer pipe, and the third core function is to filter impurities such as hair mixed in the ground sewage and prevent the impurities from entering the floor drain to cause blockage.
The common floor drains in the market at present mainly comprise a water seal floor drain and a mechanical closed floor drain. However, in practical use, both of these two kinds of floor drains cannot prevent the smell from returning 100%, and the smell can be occasionally returned after the floor drain is used for a period of time.
Under normal conditions, after ground water flow is drained into a sewer pipe from the floor drain, the odor return prevention functional structure of the floor drain is closed to seal the sewer pipe and prevent the sewer pipe from returning odor. However, sometimes the odor-returning prevention function of the floor drain fails due to the evaporation of water in the water seal of the water seal floor drain or the hair being stuck on the baffle of the mechanical closed floor drain, and the odor of the sewer pipe returns to the indoor environment.
Under the normal condition, when the odor-returning prevention functional structure of the existing floor drain is not tightly sealed on a sewer pipe, a user cannot visually check the odor-returning prevention functional structure on the surface of the floor drain, so that when the floor drain begins to return odor, the user cannot find and process the odor-returning prevention functional structure in time, and only when the odor is diffused in a room and the nose of people can smell the odor, the user can know that the odor-returning of the floor drain is caused.
People do not want the sewer to return odor, but people can not disassemble the floor drain to check whether the odor-return-preventing functional structure of the floor drain is tightly closed or not after every time of water drainage. Therefore, it is the current situation that the problem of floor drain odor return occurs in many households.
