1. According to the material, it can be divided into SUS304 stainless steel, cast iron, all plastic, brass, zinc alloy material faucet, polymer composite faucet and other categories.

2. According to function, it can be divided into basin, bathtub, shower, kitchen sink faucet.

3. According to the structure, it can be divided into single-type, double-type and triple-type faucets. In addition, there are single handles and double handles. The single-connected type can be connected to the cold water pipe or the hot water pipe; the double-connected type can connect two hot and cold pipes at the same time, and is mostly used for the bathroom sink and the faucet of the kitchen sink with hot water supply; the triple-type hot and cold water is removed. Outside the pipe, it can also be connected to a shower head, mainly used for the faucet of the bathtub. The single handle faucet can adjust the temperature of the hot and cold water through one handle, and the double handle needs to adjust the cold water pipe and the hot water pipe separately to adjust the water temperature.

4, according to the way to open, can be divided into spiral, wrench, lift and induction. When the spiral handle is opened, it needs to rotate a lot of turns; the wrench type handle generally only needs to be rotated 90 degrees; the lift-type handle only needs to be lifted up to discharge water; the inductive faucet will automatically discharge water as long as the hand reaches under the faucet. In addition, there is a time-closed faucet. After the switch is turned off, the water will flow for a few more seconds before stopping, so that the dirty things on the hands when the faucet is closed can be washed again.

5. According to the valve core, it can be divided into rubber core (slow open valve core), ceramic valve core (fast open valve core) and stainless steel valve core. The most critical factor affecting the quality of the faucet is the spool. The use of rubber core faucets is mostly screw-type open cast iron faucets, which have now been basically eliminated; ceramic valve faucets have appeared in recent years, the quality is better, now more common; stainless steel valve cores have only recently appeared, more suitable Areas with poor water quality.

5. Faucet water purifier

The main water purification technologies for faucet water purifiers are as follows: (1) Activated carbon technology Fujian Tianbing Water Purifier is the main water purification material for activated carbon as the leading water purifier. The nano-active filter has better adsorption capacity. It has a good filtering effect on chlorine, heavy metals and pesticides in water before adsorption is saturated. (2) Hollow fiber technology Japan's Toray and Mitsubishi Rayon, domestically produced home water, etc. use a hollow fiber membrane-based water purification technology, which can filter out most of the pollutants in the water, and need to replace the filter core regularly. (3) Ceramics and nano-KDF technology Most domestic products adopt microporous ceramic filter cores and nano-KDF filter materials, dechlorination balls and alkaline balls. The water discharge flow is larger than that of hollow fiber technology. The water purifier and ceramic filter can be used repeatedly for cleaning. After a certain service life, the filter element should be replaced regularly.
