Abstract

The invention discloses a membrane rolling structure, which comprises a central pipe and a membrane roll, wherein the central pipe comprises a filter material body and end covers, the end covers are connected to the two ends of the filter material body respectively, a flow channel is formed in the center of the filter material body, and the two ends are embedded into the end covers and bonded andsealed with the end covers; the membrane roll comprises guide cloth, a membrane and a grid, and the membrane roll is wound on the central pipe. The central pipe is directly made of a filter material,and can be used as a front or rear filter element; in the membrane rolling structure, the central pipe is matched with the membrane roll to form the two-in-one composite filter element structure, andthe filter element is high in integration, so that when the structure is mounted on a water purifier, the structure of the water purifier is simpler, the space can be saved, and the filter element cost and the overall production cost of the water purifier can be further saved.

Description

technical field [0001] The invention relates to a rolling film structure. Background technique [0002] Most of the existing reverse osmosis water purifiers are composed of multi-stage filtration, including a pre-filter, an RO filter, and a post-filter. Too many filter elements make the structure of the water purifier more complex and bulky. The composite filter structure has gradually become a development trend, which not only optimizes the overall structure, but also saves production costs. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a roll film structure. [0004] The present invention is achieved through the following technical proposals: a film roll structure, including a central tube and a film roll, the central tube includes a filter material body and end caps, and the end caps are respectively connected to both ends of the filter material body, the There is a flow channel in...
