A water purifier may include: a filter filtering raw water to provide purified water; a discharge port through which the purified water is discharged outside; water pipes providing a flow space for the purified water to flow; a flow path module including a body part supporting the water pipes; and a tubing assembly detachably connected to the water pipes to selectively open and close at least a portion of the water pipes when connected thereto. The tubing assembly has one side connected to the filter and the other side connected to the flow path module, and the flow path module receives the purified water filtered by the filter through the tubing assembly. The flow path module may be placed above the tubing assembly, and disposed between the filter and the discharge port while overlapping at least a portion of the tubing assembly without overlapping the filter when viewed from above.

A water purifier that purifies water to provide purified water may include: a purified water tank accommodating the purified water; and a discharge port discharging the purified water to an outside of the water purifier. The purified water tank may include: a tank main body that provides an accommodation space for accommodating the purified water; a discharge buffer part having an inlet which communicates with the accommodation space so that the purified water in the accommodation space flows in the discharge buffer part, the discharge buffer part extending in an up-down direction; an outlet tube including an insertion portion extending downward in the discharge buffer part to discharge the purified water to the discharge port through a discharge flow path; and a gasket extending from the insertion portion to an inner peripheral surface of the discharge buffer part to reduce sloshing of the purified water in the discharge buffer part.

Provided by the present invention is a faucet water purifier, a control valve and a disk assembly for a faucet water purifier, which comprises a control valve and a filtering device, wherein the filtering device defines a first communicating opening, a second communicating opening and a third communicating opening, the control valve comprises a valve body and a valve core, wherein the valve body defines a valve cavity, a first opening, a second opening, a third opening, a fourth opening, a fifth opening, a raw water inlet and a draining opening, wherein the valve core is disposed inside the valve cavity, wherein the first opening is communicated with the first communicating opening of the filtering device, the second opening is communicated with the second communicating opening of the filtering device, the fourth opening is communicated with the third communicating opening of the filtering device, the third opening is communicated with a water outlet of the filtering device, and the raw water inlet of the valve body is adapted to be communicated with a raw water source.

The invention provides filters and methods of assembling filters. In an exemplary embodiment, the filter includes a porous element, a compression element, and a housing. The compression element can be configured to receive the porous element, thereby forming an assembly. For example, the compression element can receive the porous element in a slip-fit relationship. The housing can have an opening formed therein that is configured to receive the assembly. In some embodiments, the assembly can be retained within the opening when the assembly is received therein. For example, the opening can receive the assembly in a press-fit relationship.
