Background

The water purifier is also called a water purifier, and can purify raw water (such as tap water) according to the requirements of users so as to meet the requirements of people. In many countries, especially in developing countries, with the continuous development of industry and agriculture, the problem of water pollution is more and more serious, and the water source of domestic water for people is also influenced slightly or heavily. In addition, the quality of tap water is affected by the external environment and water supply pipelines. For example, the quality of tap water is affected by excessive sand in the tap water source, aging of the pipe network, poor quality of the tap water pipe, lack of cleaning of the water supply pipe network for a long time, and the like. Thus, tap water in many countries is of poor quality and unsuitable for direct consumption, under the influence of a number of factors. The water purifier can effectively remove impurities such as silt, colloid, rust, bacteria and even heavy metal ions in raw water, thereby improving the quality of domestic water and being increasingly favored by consumers. The existing household water purifier for purifying tap water mainly comprises an under-kitchen ultrafiltration water purifier, an RO membrane water purifier, a faucet water purifier and the like. Among these water purifiers, the under-kitchen ultrafiltration water purifier, the RO membrane water purifier, and the like are limited in their application fields due to their complicated structures and large volumes. The tap water purifier has the advantages of small volume, convenient installation and disassembly, capability of automatically purifying tap water under the pressure of the tap water without electric energy and the like, and is popular among many consumers. However, the existing faucet water purifier also has a plurality of defects.
