Description
Technical field
The present invention relates to the adjustable fore filter of self-cleaning and its application method before a kind of water purifier.
Background technology
The fore filter of prior art, after being typically mounted on the water meter of house lead in waterpipe, caused by ensuring in pipe network
A large amount of precipitated impurities will not be damaged to user's human body, and positive guarantor is played to concealed pipe, tap, electrical equipment etc.
Shield acts on.However, press its operation principle so that easy attachment dirt on the filter core outer wall of fore filter, after accumulation of mud not only
Not easy cleaning, but also the filter effect of fore filter can be influenceed.And because some dead angles can deposit many impurity on its inwall,
Therefore reach that to clean up be relatively difficult, and cumbersome using common manual teardown blowdown mode.Modern such
In allegro life, user is likely difficult to clean on time, and the blocking of filter core outer wall, or the iron in water are will result in after permanent
Rust, suspension, into dirty material tap will be flowed directly out, if this water is drunk into after human body, life and health will be caused
Very big harm.On the other hand, home sector water, including clear lavatory are allowed after fore filter being arranged on into water meter, clean-up
Deng water is used, will also pass through fore filter is filtered, and some are wasted rather.Further, the water quality of some northern areas is harder, if by before
Put after filter is placed in water meter, filter harder raw water for a long time, the waste of filter element replacing and material will be greatly increased, if but by its
Used before being placed in water purifier, only allow water and drinking water for kitchen use to be filtered, then can extend the use longevity of its own and water purifier
Life.Therefore, market is needed in specific environment with the conditions of, the self-cleaning used before a kind of water purifier and regulatable prefilter
Device.
