Composite filter element and water purifier with same

Abstract

The invention discloses a composite filter core and a water purifier with the composite filter core, wherein the composite filter core comprises a casing, a composite filter core body, a top cover and a press cover; a filter core taking-out opening is formed in the casing; the composite filter core body is arranged in the casing and can pass through the filter core taking-out opening; the composite filter core body comprises a plurality of filter core layers; the top cover is arranged on the top of the composite filter core body; the press core is detachably fixed at the filter core taking-out opening part and tightly presses the top cover on the top of the composite filter core body. The composite filter core according to the embodiment of the invention has the advantages that the composite filter core body, the top cover and the press cover are sequentially and detachably arranged in the casing, so that the press cover tightly presses the top cover on the top of the filter core body; the fixed installation of the composite filter core body is ensured; in addition, the top cover and the composite filter core body can be conveniently taken out from the filter core taking-out opening; when the filter core needs to be replaced, the press cover, the top cover and the composite filter core body only need to be sequentially taken out and then installed; the core replacing actions are few, the core replacing cost is low, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a composite filter element and a water purifier having the same. Background technique [0002] In related technologies, water purification equipment uses PP cotton, activated carbon, etc. as pre-filter elements, and then connects RO filter elements in series to form a water system connected by multi-stage filter elements for water purification. The pipeline connection of the whole system is complicated, installation and replacement are inconvenient, multi-joint connection, and many risk points of water leakage. More importantly, the service life of multi-stage filter elements is inconsistent. Consumers need to replace as many as three to five filter elements. Frequent purchase of filter elements is required and professional installers need to replace them. The consumer experience is poor and the overall cost is high.
