Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of tap special-purpose cleaner, and its volume is little, and is simple in structure, and cost is low, reliable operation.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

The special-purpose cleaner of a kind of tap, has housing, the bottom of fixedlying connected with housing seal, in order to the soft interface that is connected with tap, be located at the filter core in the housing, the middle part of bottom has delivery port, its technical scheme is that it also has to be located at and turns over the water platform above the described filter core, turn over the die cavity that the water platform is a upper end open, its upper end open place has outward extending edge, filter core is tubular, the die cavity that turns over the water platform stretches into the endoporus of filter core, its edge is supported by the upper surface of filter core, it is spacing by filter core to turn over the water platform, the lower surface of filter core contacts with bottom and is spacing by bottom, the endoporus of filter core is connected with delivery port on the bottom, turn over have the upper surface of guaranteeing to turn over the water edge of table and filter core between the top inner wall of the upper surface of the upper surface of water edge of table or filter core and housing the upper surface respectively and form the supporter in gap between the top inner wall of housing, the middle part, upper surface of housing has the connector that stretches into one section tubular in the housing, described soft interface is fixedly connected with connector and be connected, connector stretches in the die cavity that turns over the water platform, the bottom face of connector and lateral surface are respectively and turn over the diapire of die cavity of water platform and the gap between the madial wall, the gap of turning between the top inner wall of the upper surface of water edge of table and housing forms first water channel, the upper surface of filter core and lateral surface respectively and the top inner wall of housing and the gap between the madial wall form second water channel, described first water channel is connected with second water channel.

In the technique scheme, it is cylindric that described connector preferably is, connector has internal thread, the bottom of described soft interface has external screw thread, soft interface is threaded with connector and is connected, and preferably is set with the retaining cover of annular in the soft interface in the corresponding section of the position that is threaded therewith.Delivery port place on the above-mentioned bottom preferably is fixed with filter screen.Upper surface preferably neat mutually with the upper surface of filter core or that turn over the water edge of table, above-mentioned upper surface of turning over the water edge of table exceeds the upper surface of filter core, and described supporter is preferably and is positioned at a plurality of projections upper surface, that be evenly distributed of turning over the water edge of table.The lower surface of above-mentioned filter core by the spacing concrete structure of bottom can be, the upper surface of bottom has an annular projection in the delivery port position, and this annular projection stretches into the endoporus of filter core and filter core is spacing.The top of above-mentioned soft interface preferably is set with the larynx hoop that it is connected with tap.The above-mentioned die cavity that turns over the water platform is preferably cylindrical, turns over the water platform by the spacing concrete structure of filter core can be, it stretches into the die cavity of endoporus of filter core and the endoporus of filter core matches in the junction to turn over the water platform.

Said structure of the present utility model makes current turn to 180 ° to turn to 90 ° through turning over the water platform at first water channel by soft interface again, enter second water channel (filter space) from first water channel, because filter core compresses, therefore the current that enter second water channel can only enter the endoporus of filter core by filter element filtering, flow out through the filter screen current.The utility model is mounted in a kind of pure physical filtering device on the running water tap delivery port, the filter core precision is at 1 micron, can remove the particulate matter more than 1 micron in the water, filter out above three kinds of materials of mentioning in the background technology, be organic granular material, organism in water particulate matter in inorganic particle material, the water in the water, make household drinking water reduce organic or inorganic impurity, reliable operation.Owing to adopt soft interface, just dock with faucet outlet and be easy to, for more firm, adopt the larynx banding solid, also adopted the structure that increases the retaining cover, and in case use when mixing water valve water temperature to raise to produce to become flexible, it is more reliable to work.The cleaner that is installed in faucet outlet is too high can be used in influence, and the too low filter element life that then influences is through experiment repeatedly, think that whole height is proper at 60mm, the utility model has adopted this size, its volume little (miniaturization), simple (just) is installed, is easy to change.Housing is preferably transparent, so that the user supervises the cleaner working condition, takes relative measure for accident.Simultaneously it water quality detection is very favourable for various places water supply network system, can obtain the actual measurement thing beyond the conventional detection.Very necessary especially for state of emergency situation.Avoided water supply pipe in bad repair and have visible biology to enter the generation that pipeline causes accident.Also have, the delivery port place on the above-mentioned bottom is fixed with filter screen, can prevent that foreign material from entering in the housing from delivery port, and it is more reliable to work.The utility model is simple in structure, cost is low, filter effect is obvious, has compact overall structure, rational characteristics.It has adopted the material of safety and sanitation, and the recyclable utilization of material is environmental.
