Description

A faucet water purifier with a three-stage water outlet structure

technical field

The invention relates to the technical field of faucet water purifiers, in particular to a faucet water purifier with a three-stage water outlet structure.

Background technique

The water purifier can purify raw water (for example, tap water) according to the user's requirements, so that it can meet people's needs. In many countries, especially in developing countries, with the continuous development of industry and agriculture, the problem of water pollution has become more and more serious, and the water sources of people's domestic water have also been slightly or severely affected. In addition, the water quality of tap water will also be affected by the external environment and water supply pipelines. For example, too much sand in the tap water source, aging pipe network, poor quality of tap water pipes, and lack of cleaning of the water supply pipe network for a long time will all affect the water quality of tap water. Therefore, under the influence of many factors, the quality of tap water in many countries is poor and not suitable for direct drinking. The water purifier can effectively remove impurities such as sediment, colloid, rust, bacteria, and even heavy metal ions in raw water. Some existing faucet water purifiers have a three-stage structure, which can be switched between the three functions of water purification, shower and air bubbles by using a switching valve. Three water distribution ports are set on the partition, and the water inlet is switched between the three water distribution ports through a rotating valve core, and a sealing ring needs to be set between the valve core and the partition plate, but this setting method is difficult to obtain during the switching process. The middle sealing ring is prone to wear and tear, resulting in poor sealing effect and low service life.
