Abstract: Disclosed is a water dispenser. The water dispenser includes a water outlet component; a water cooling module for accessing a water source, an output port of the water cooling module being communicated with the water outlet component through a first water pump; and/or a water heating module, an input port of the water heating module accessing the water source through a second water pump, an output port of the water heating module being communicated with the water outlet component, the water outlet component accessing the water source through the second water pump.

Abstract: Provided are a central tube for a filter cartridge and a filter device having same. The central tube (100) comprises a first half tube (1), a second half tube (2) and a membrane element (3), wherein the first half tube (1) has a first mating surface, and the first mating surface is grooved to form a first flow channel (111); the second half tube (2) has a second mating surface, the second mating surface is grooved to form a second flow channel (21), and the first half tube (1) and the second half tube (2) are butt-jointed to form a hollow, straight tube shape; and the membrane element (3) is arranged between the first half tube (1) and the second half tube (2) and seals the first flow channel (111) and the second flow channel (21), respectively.

Abstract: Disclosed is a water softener that includes a water softener valve and an ion exchange tank. The water softener valve includes a valve body and valve core assembly. The valve body includes a valve chamber, and a water inlet passage and a water outlet passage in communication with the valve chamber. The valve chamber, the water inlet passage, and the water outlet passage all extend in a first orientation, and the water inlet passage and the water outlet passage are both located at a periphery of the valve chamber and are disposed on opposite sides of the valve chamber in a second orientation. The water inlet passage and the water outlet passage respectively define a water inlet and a water outlet at a same end of the valve body along the first orientation. The second orientation and the first orientation are perpendicular to each other.
