A spill proof floor drain is a floor drain that prevents water from overflowing. A floor drain is a must-have tool for every household. One or several floor drains are installed in every bathroom for use at the intersection of drainage pipes. Traditional floor drains are only used to block large garbage, such as clumps of hair and large debris, from entering the sewer and blocking its operation. However, there are often many accidents in the sewer where the odor in the bathroom is very unpleasant due to the leakage from the floor drain. A spill proof floor drain can effectively solve such problems. Below, the editor will introduce in detail the anti overflow floor drain.

The principle of preventing overflow floor drain:

1. Water sealed floor drain

Most water sealed floor drains have shallow water seals and too little sealing capacity, which can dry up and cause odor due to factors such as time and dry weather; Moreover, the deeper the water seal height, the more it will affect the drainage speed (Jiajia'an, Liufang, Huoxiang, Juweijing, submarine second-generation), and the more serious the sedimentation of dirt, making it difficult to clean.

2. Spring sealed floor drain

Divided into upward and downward styles. The pop-up function is to press the cover plate, which will bounce up and reset when pressed again; The downward spring type is sealed by stretching the sealing gasket at the lower end of the sealing core with a spring. Due to the fact that the spring is made of boron iron, it is prone to rusting and gradually weakens its elasticity until it fails, resulting in a short lifespan. Additionally, the spring is prone to entanglement with hair and fabrics, making it difficult to clean.

3. Magnet sealed floor drain

Use the magnetic force of two magnets to attract the sealing gasket for sealing. Due to the poor quality of surface water, such as washing items and floors, the pollution may contain some iron impurities adsorbed on the magnet. After a period of time, the impurity layer will cause the sealing gasket to fail to close. In addition, due to the effect of the Earth's large magnetic field, the magnetic force will gradually weaken.

4. Double storage water trap floor drain

This type of structural floor drain has only recently appeared in the market. Its principle breaks through all vertically designed structures and horizontally designed floor drains. Its structure is simple but very effective in solving the shortcomings of the above structure. The double trap structure has a sealed water volume that is not easy to evaporate, and has good anti insect and anti odor effects, balancing the two conflicting functions of floor drains (drainage, anti odor and anti insect). The appearance of this structure may rewrite some indicators of the existing national floor drain standards.
