Description

Technical Field

[0002] Some kitchen faucet nozzle products currently on the market have the function of switching water outlet modes (the water outlet mode is divided into normal water outlet mode and bubble water outlet mode). Users can select the water outlet mode according to their needs. This type of faucet nozzle does not have a water purification function. The water purification function of the faucet mainly relies on the installation of a water purifier (with a water purification filter element) under the countertop. Since a water purifier needs to be installed under the countertop, the faucet water connection is complicated and the installation is troublesome. In addition, the filter element of the water purifier is not easy to check the remaining service life under the countertop, and it is not convenient to replace it, resulting in a poor user experience. Some existing water purification filter elements are not convenient for users to switch between raw water and purified water when using water.

[0003] In addition, some existing multifunctional faucet nozzles have a structure with a water outlet mode switching function, and the internal water path structure is complex. Considering the installation space, flexibility of use, aesthetics, production cost, etc., the internal structure of the kitchen faucet nozzle product should not be designed to be too complicated, and the volume should not be designed to be too large. Therefore, the existing nozzles with a water outlet mode switching function have a relatively small internal design space, which brings design difficulties to the structure with an added water purification function.
