1. Classification of deodorant floor drains: water-sealed VS self-sealing floor drain
Deodorant floor drains can be divided into two categories in terms of structure: water-sealed deodorant floor drains and self-sealing deodorant floor drains. The principle of water-sealed deodorant floor drains is to use the water in the drain trap to achieve the sealing effect, while self-sealing deodorant floor drains generally use springs. , magnets, bearings and other mechanical devices or soft materials seal the odor of the floor drain.

(1). Introduction of new water-sealed floor drain
The traditional water-sealed floor drain has a simple structure, and although the deodorant effect is good, there are also many problems. With the advancement of technology, on the basis of traditional water-sealed floor drains, new types of water-sealed and deodorant floor drains with various structures have appeared. It not only improves the deodorant ability, but also avoids some drawbacks of traditional floor drains.
(2). Introduction of self-styled floor drain
To solve the shortcomings of traditional water-sealed floor drains, one is to study improved water-sealed floor drains, and the other is to study other isolated and sealed self-sealing devices to replace water seals, so as to completely avoid self-sealing floor drains that do not store water for a long time and dry up. The current self-sealing floor drains are generally sealed and deodorized through mechanical devices or silicone materials. Self-sealing floor drains have good deodorization, drainage and self-cleaning capabilities, but because most of them are controlled by mechanical devices, there are failures.
2. Choose the deodorant floor drain according to the space used
Water-sealed floor drains are more odor-proof, and self-sealing floor drains have relatively smooth drainage. Both have their advantages and disadvantages. In order to promote strengths and avoid weaknesses, it is recommended to use different floor drains for different spaces. For places where water is often used, deep water sealing floor drains can be used. For example, the shower area has a large drainage area. Water sealing floor drains are more odor-proof and less prone to failure; self-sealing floor drains are more suitable for places where water is not frequently used. For example, kitchens or balconies are generally only used for Temporary drainage, using self-sealing floor drains can avoid the situation that the water-sealed floor drains dry up and do not deodorize; in addition, for washing machines and other large-displacement floor drains, try to choose straight-type self-sealing floor drains.
