Abstract: An intelligent water purifying system includes a water purifying module, a heating module, a raw water inlet port, and a pure water outlet port. An inlet end of the water purifying module is connected and in communication with a raw water inlet port, a water outlet end of the water purifying module is connected and in communication with an inlet port of the heating module, and an outlet port of the heating module is connected and in communication with a hot water output pipe. The heating module includes: a heating tank for storing water, and a heating module controller used to control heating of pure water in the heating tank to a preset temperature. The intelligent water purifying system is able to provide water purifying and heating functions at the same time.

Abstract: A filtering device includes a hollow body, a filtering core assembly securely received inside the body and composed of an outer filtering core and an inner filtering core securely received inside the outer filtering core. A first switch device is mounted at a bottom end of the body and operably connected to a bottom of the filtering core assembly. A second switch device is mounted at a top end of the body and operably connected to a top of the filtering core assembly. A first chamber is defined between an inner face of the body and an outer periphery of the outer filtering core. A second chamber is defined an inner periphery of the outer filtering core and an outer periphery of the inner filtering core. A third chamber is defined inside the inner filtering core, wherein the first switch device controls communication between the first chamber and the second chamber.

Abstract: A three-way connector includes a body provided with an inlet, a first outlet in line with the inlet, a first waterway defined to communicate the inlet with the first outlet and a second outlet communicating with the inlet and the first outlet via a second waterway vertically defined relative to the first waterway. A filter assembly is received inside the first waterway and having a texture in line with the first waterway.
