Description

Technical Field

[0001] The utility model relates to the technical field of bathroom appliances, in particular to a fine sand filtering faucet. Background Art

[0002] The existing tap water supply system often cannot guarantee the purity of the water quality, especially in some areas, where there are more pollutants such as fine sand, impurities, microorganisms, etc. in the tap water, which poses a potential threat to people's health. Therefore, most of the current bathroom faucets are equipped with filtering structures to intercept impurities such as fine sand and dust in the tap water.

[0003] In the existing bathroom faucets with filtering structures, the filtering structure is generally arranged inside the faucet. After the faucet has been used for a period of time, the internal filtering structure of the faucet will intercept too many impurities, which will cause the fluidity to decrease, resulting in a decrease in the water flow rate of the faucet. Therefore, the filtering structure needs to be cleaned regularly. The traditional faucet filtering structure is arranged inside it. When cleaning the filtering structure, the faucet needs to be disassembled, which is time-consuming and laborious. In addition, the sealing ring is easily lost during the disassembly process, causing unnecessary trouble. Utility Model Content
