5. Spring-type floor drain: divided into upper and lower types. The spring-up type is to press the cover plate, the cover plate bounces up, and when pressed again, it will reset; the spring-down type is to use the spring to stretch the sealing gasket at the lower end of the sealing core to seal. Since the spring is made of boron iron, it is easy to rust and its elasticity gradually increases. It will weaken until it fails, and the life is not long. In addition, the spring is easy to entangle the hair and fabric, and it is not easy to clean.
Advantages: good deodorant effect. Disadvantages: slow drainage, and easy to block for home use.
6. Flap floor drain: It is to use gravity to open when there is water, and close when there is no water. It looks like it will deodorize, but the actual use is quite different.
Disadvantages: These self-sealing floor drains are not deodorant, easy to block, and have a short lifespan. Advantages: There are more choices of panel styles.
7. Floating ball floor drain: use the buoyancy of water to float a ball to close the drain to achieve deodorant function. When the water flows into the drain outlet of the floor drain, the buoyancy of the water lowers the floating ball and floats the sewage out. When there is no water, the floating ball will close the drain to achieve the sealing function. Frequent cleaning is required.
Disadvantages: poor drainage function, easy to block, easy to retain dirt to cushion the floating ball and lose the sealing function. Advantages: long life.
8. Plastic basket floor drain: A plastic basket is used instead of the buckle bowl. This is another form of water-sealed floor drain, but it is more convenient to clean.
