Description
Technical field
The utility model belongs to art of filters, more particularly to a kind of pair scrapes filter.
Background technology
The filter of prior art includes shell, the cleaning fixed mount being located in shell, is set on cleaning fixed mount
Inner core, interior core outer surface fixed cover are provided with screen pack, as illustrated in fig. 1 and 2, when filter works, the cleaning function of filter
It is realised in that：When inner core rotates, relying solely on the inwall wall of the cleaning fixed mount for the outer surface for being close to screen pack will remain
Dirt impurity in screen pack outer surface wipes out, but be primarily present erasing area it is small, erasing it is uneven so that cleaning performance compared with
Difference, the inwall wall for cleaning fixed mount is even likely occurred by the extruding of dirt impurity so that dirt impurity together penetrates with liquid
The shortcomings that screen pack.
In order to solve the above-mentioned technical problem, people have carried out long-term exploration, such as Chinese patent discloses a kind of pair and scraped
Wash filter [application number：CN201520460502.2], including shell 4, be located in shell 4 cleaning fixed mount 1, be located at cleaning
Inner core 2 on fixed mount 1, the outer surface of inner core 2 are fixed with screen pack 3, it is characterised in that：Clean fixed mount 1 and be provided with cleaning
Device, water flow into from the side of shell 4, by screen pack 3 filter out dirt impurity after flow into inner core 2, cleaning device is by screen pack
The dirt impurity of 3 outer surfaces residual is disposed, and cleaning device includes the fixed cleaning item 5 being located on cleaning fixed mount 1, cleaning item
5 outer ends are against on the outer surface of screen pack 3 and scrape the dirt impurity that the outer surface of screen pack 3 remains.
Although such scheme sets silica gel cleaning item to be cleaned to screen pack by blocking on cleaning fixed mount, accelerate
Cleaning item scrapes the dirt impurity of screen pack outer surface residual, improves cleaning performance and filter efficiency, but it can only be right
Screen pack, which carries out cleaning, to be cleaned to the inwall of shell, due to screen pack during cleaned easily by under cleaning
The impurity come is attached on outer casing inner wall, and the structure do not cleaned to outer casing inner wall easily causes the pollution of outer casing inner wall,
And then cause the pollution of screen pack and influence the attractive in appearance of filter.
