Description
Technical field
The present invention relates to water-treatment technology field, particularly relate to a kind of technology of the fore filter with interior brush.
Background technology
Along with the raising of the progressive people's living standard of science and technology, people starts having had higher requirement with water and healthy diet in daily life.The control that the water supply in city causes the water degradation of domestic water and water equipment due to secondary pollutions such as ducted iron rust, silts is malfunctioning; and make other relate to reduce with the Domestic electrical equipment life of water; even produce huge potential safety hazard; therefore; from large environment, every household all needs to install fore filter to improve water quality and protection domestic water equipment.Fore filter is the jinx of secondary pollution, is a kind of device for filtering impurities reliably.
The fore filter of existing market mainly comprises along types such as wash type, backwash type, siphon types.But there is different problem problems in dissimilar fore filter:
Very weak along the backwash rate rinsing fore filter, filter core is easily blocked, and not only less impurity rinses not out, on the contrary in filter core embedding more deeply, tighter, easily become secondary pollution, consumer needs to open housing and filter core is brought out scrubs with toothbrush, takes time and effort.
Siphonic fore filter product structure is complicated, it is thorough to rinse, if water-quality ratio is poor, impurity in filter core embedding more deeply, tighter, finally cause filter core to block, cause secondary pollution, get up very difficult once filter core blocks maintenance.On the other hand, most siphonic fore filter product sacrifices filtering accuracy to reach developing result, and usual filtering accuracy is all more than 50 microns.As Chinese patent: on 201520252203.X (application number) the fore filter technology announced, be exactly a kind of typical siphonic fore filter.
Chinese patent: 201510243765.2 (application numbers) disclose a new technology, its denomination of invention is " two-way powerful hydro-peening fore filter ", be integrated with two kinds of functions along flushing and backwash, substantially the drawback only having one-way flushing function of the existence of fore filter is in the market solved, but internal structure is too complicated, discharge is influenced and manufacturing cost is higher.
At present, the fore filter that backwash type fore filter compares other has had some to improve technically, but run into the trapped substance be blocked in opening of sieve, need to open filter flask and take out filter screen, with the cleaning of the auxiliary instrument such as hairbrush (available toothbrush replacement), air gun, also make troubles to user.
At present, fore filter is on the market roughly in T shape, and for the owner of renovated old community, this T-shaped fore filter accesses as wanted Late reformation, due to the restriction in space in meter box, is difficult to transformation.
