Description
Technical field
The present invention relates to Domestic water purifying fields, about the compound integrated morphology of a variety of filter materials, more particularly to inside and outside one kind
The combined filtration component of filter core energy relative rotation
Background technique
Currently, the filtering of Domestic water purifying, most of to improve mouthfeel filtering using preposition coarse filtration, the filtering of film essence and postposition.
But the filtering of so more filter materials is completed, previous water purifier needs to install multiple filter cores, and every filter core is packed into different filters
Material completes above-mentioned filtering, obtains the drinking water of high-quality mouthfeel, and the quantity of filter core increases, occupies therewith in household water filter
Volume is also just quite big, causes the volume of water purifier larger, the use in family brings many inconvenience, and small size is net at present
Approval and favor of the hydrophone increasingly by market, so each component of water purifier needs to carry out integrated and modularization, filter core
Integrated and modularization mainly uses the compound of filter core multistage filter material.
The current composite filter element in market is more using being realized inside single filter core by multilayer fixed structure mostly
Kind of filter material it is compound, but due to the stationarity of structure, there is considerable restraint in filter material complex method and diversity, and due to
Reasons in structure will also result in filter core cannot be using conveniently detaching structure；
The present inventor based on years of experience and practice in relevant industries, proposes that a kind of inside and outside filter core energy is opposite as a result,
The combined filtration component of rotation, to overcome the deficiencies of existing technologies.
Summary of the invention
The purpose of the present invention is to provide a kind of combined filtration components of inside and outside filter core energy relative rotation, to solve above-mentioned back
The problem of being proposed in scape technology.
The invention provides the following technical scheme:
A kind of combined filtration component of inside and outside filter core energy relative rotation, including external filter element and built-in filter core, it is described external
