Technical Field
The invention relates to the technical field of water treatment, in particular to a technology of a pre-filter with an inner brush.
Background
With the improvement of the living standard of people along with the progress of technology, people begin to have higher demands on water and dietary health in daily life. The secondary pollution of rust, sediment and the like in the pipelines causes the water quality of domestic water to be poor and the control of water equipment to be malfunctioning, reduces the service life of other domestic appliances related to water and even generates huge potential safety hazards, so that from the aspect of large environment, all household users need to install a pre-filter to improve the water quality and protect the domestic water equipment. The pre-filter is a secondary pollution gram and is a reliable impurity filtering device.
The pre-filters in the current market mainly comprise a forward flushing type, a back flushing type, a siphon flushing type and the like. However the process comprises, different types of pre-filters have different problems:
the flushing strength of the forward flushing filter is very weak, the filter element is easy to be blocked, smaller impurities cannot be flushed out, the filter element is embedded deeper and tighter, secondary pollution is easy to occur, and a consumer needs to open the shell to take the filter element out of the toothbrush for brushing, so that the time and the labor are consumed.
The siphon type pre-filter product has a complex structure, is not thoroughly washed, is deeper and tighter in the filter element due to impurities embedded in the filter element if the water quality is relatively poor, finally causes the blocking of the filter element, causes secondary pollution, and is very difficult to maintain once the blocking of the filter element. On the other hand, most siphon-type pre-filter products sacrifice filtration accuracy for flushing, usually the filtering accuracy is all above 50 microns. Such as Chinese patent: pre-filter technology published on 2015152203. X (application number), is a typical siphon type prefilter.
Chinese patent: 201510243765.2 (application number) discloses a new technology, the name of which is 'bidirectional powerful spray washing prefilter', integrates two functions of forward flushing and back flushing, basically solves the defect that the prefilter in the current market has only one-way flushing function, but has the defects of excessively complex internal structure, influenced water flow and higher manufacturing cost.
At present, compared with other prefilters, the back flushing type prefilter has some improvements in technology, but the filter flask is required to be opened to take out the filter screen when the filter screen is blocked by the trapped matters in the filter screen holes, and auxiliary brushes (which can be replaced by toothbrushes), air guns and other tools are used for cleaning, so that the filter screen brings trouble to users.
Currently, the pre-filter on the market is approximately T-shaped, and if the post-reconstruction access of the T-shaped pre-filter is required for the owners of the old and decorated communities, the post-reconstruction access is difficult due to the limitation of the space in the water meter box.
