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

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

3. According to the structure, it can be divided into several types of faucets such as single type, double type and triple type. In addition, there are single handles and double handles. Single type can be connected to cold water pipe or hot water pipe; double type can be connected to both cold and hot pipes at the same time, mostly used for bathroom basins and kitchen sinks with hot water supply; triple type except for two cold and hot water pipes In addition to the pipes, shower nozzles can also be connected, mainly for bathtub faucets. The single-handle faucet can adjust the temperature of cold and hot water with one handle, while 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 opening method, it can be divided into screw type, wrench type, lift type and induction type. When the screw handle is opened, it needs to rotate many times; the wrench-type handle generally only needs to rotate 90 degrees; the lift-up handle only needs to be lifted up to discharge water; the inductive faucet will automatically discharge water as long as the handle is under the faucet. In addition, there is also a faucet that is closed with a delay. After the switch is turned off, the water will flow for a few seconds before stopping, so that the dirt on the hand can be washed away when the faucet is turned off.

5. According to the valve core, it can be divided into rubber core (slow opening valve core), ceramic valve core (quick opening valve core) and stainless steel valve core. The most important thing that affects the quality of the faucet is the valve core. Faucets using rubber cores are mostly screw-opening cast iron faucets, which have been basically eliminated; ceramic valve core faucets have appeared in recent years, with better quality, and are now more common; stainless steel valve cores have only recently appeared and are more suitable Areas with poor water quality.

6. Faucet water purifier

The main water purification technologies used in faucet water purifiers are as follows: (1) Activated carbon technology Fujian Tianbing Water Purifiers all think that activated carbon is the main water purification material for faucet water purifiers, and the adsorption capacity of nano active filter elements is relatively good. Before the adsorption is saturated, it has a relatively good filtering effect on chlorine, heavy metals, and pesticides in the water. (2) Hollow fiber technology Japan's Toray and Mitsubishi Rayon, domestic Jiayou Water, etc. use hollow fiber membrane-based water purification technology, which can filter most of the pollutants in the water, and the filter element needs to be replaced regularly. (3) Ceramic and nano-KDF technology. Most domestic products adopt water purification technology based on microporous ceramic filter elements and nano-KDF filter media, dechlorination balls, and alkaline balls. The water flow rate is greater than that of hollow fiber technology. The water purifier and the ceramic filter element can be repeatedly cleaned and used. After a certain service life, the filter element needs to be replaced regularly.
