Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1 and Figure 2, a kind of filter for purifier of the present invention, can be described as " not needing the filter core changed ", also can be described as " forever nonclogging filter core ", it comprises housing 1 and metal screen, and housing 1 comprises the first housing 11 and the second housing 12 be mutually tightly connected, and housing comprises a water inlet 13 and a delivery port 14, metal screen is longitudinally embedded in the inner chamber of housing 1, and the cross sectional shape of the shape of metal screen and housing cavity matches.
In the present invention, metal screen is the sintered meshwork 2 sintered by multilevel-cell filter screen, and in order to ensure the quality of filtered water, the precision of sintered meshwork is 8 μm-0.01 μm, and sintered meshwork 2 is made up of 2 to 12 layer unit filter screens.Preferably, this sintered meshwork is made up of 5 layer unit filter screens, and the precision of sintered meshwork is 1 μm, 2 μm or 3 μm.In the present invention, precision near the unit filter screen of water inlet side is less than the precision of delivery port side unit filter screen, when running water enters in purifier by water inlet, oarse-grained impurity and heavy metal molecules first filter by the unit filter screen of influent side, then short grained impurity and heavy metal molecules are successively by other unit strainer filterings.
In the present invention, one end that first housing 11 is connected with the second housing 12 is provided with concave station rank 111, one end that second housing 12 is connected with the first housing 11 is provided with boss rank 121, the inner surface on concave station rank is provided with internal thread, the outer surface on boss rank is provided with external screw thread, internal thread and external screw thread are sealed and matched, and the first housing 11 and the second housing 12 are tightly connected.In order to better reach goal of the invention of the present invention, the first housing 11 and the second housing 12 junction are provided with sealing strip 3 further.
As shown in Figure 3, for another kind of the present invention is used for the filter of purifier, it comprises housing 4 and is embedded at the sintered meshwork 2 in this housing 4, housing 4 has the first housing 41 and the second housing 42 to form, connection 43 place between first housing 41 and the second housing 42 adopts welded seal to connect, and can reach goal of the invention of the present invention equally.In addition, can also adopt between the first housing with the second housing to glued joint and to be connected or the connected mode that the two secure seal links together can connect by other.
As shown in Figure 4, for another filter for purifier of the present invention, it comprises the housing 5 be made up of the first housing 51 and the second housing 52, the two ends of housing 5 are respectively provided with a water inlet 53, longitudinally two sintered meshworks 2 are embedded with in the inner chamber of housing, these two sintered meshworks 2 are sintered by multilevel-cell filter screen and form, and be provided with certain distance between these two sintered meshworks 2, are provided with delivery port 54 in the bottom of housing 5 between two sintered meshworks 2.
In the present invention, metal screen can also be by metal dust or metallic fiber sintered sintering felt, and the precision of sintering felt is 5 μm-1 μm, and preferably, the precision of sintering felt is 5 μm.Sintered meshwork or sintering felt adopt 304 stainless steels, 316L stainless steel or copper product or other metal materials meeting food contact material standard to make, and the first housing and the second housing adopt plastic material injection molded.
The present invention has got three kinds of different stainless steel sintered meshworks respectively and a kind of sintering felt is tested, and test result meets the requirements completely, and test result is as follows:
In the present invention, if adopt 5 layers of filtering accuracy to be the filtration of sintered meshwork for running water of 1 μm, 2 μm or 5 μm, especially the sintered meshwork of 1 μm is adopted to filter, the impurity of less than 1 μm and heavy metal can be filtered out, more than this filter effect high twice than the pre-filtering device of at present all on the market purifiers.Further, filtering accuracy can also be adopted to be the sintering felt of 5 μm.And more high-precision sintered meshwork or sintering felt can also be utilized to filter, as long as impose suitable pressure, filter effect can set as required, and this will improve the quality of drinking water significantly, reduces the replacement cost of the filter core of purifier.
Filter for purifier of the present invention, directly makes filter with sintered meshwork and is arranged on running water pipe, thus replaces the cotton filter core of traditional PP or other filter core carries out prefilter, and coordinates RO film filter; In addition, according to water quality situation, sintered meshwork filter, RO film filter and active carbon filtering device can also be carried out any combination and filter, as:
1, sintered meshwork filter, the combination of RO film filter;
2, sintered meshwork filter, active carbon filtering device combination;
3, sintered meshwork filter, active carbon filtering device, the combination of RO film filter;
4, sintered meshwork filter, RO film filter, active carbon filtering device combination;
5, sintered meshwork filter, active carbon filtering device, RO film filter, active carbon filtering device combination.
Further, the filter for purifier of the present invention, carries out the prefilter of running water with metal screen.In use procedure, water inlet and delivery port are respectively equipped with triple valve and calutron, water intaking valve in Water treatment on water inlet and the outlet valve on delivery port are opened, and running water enters purifier and flows out through delivery port after sintered meshwork or sintering felt filter and drinks.When after filter work a period of time, water intaking valve, outlet valve is closed, cleaning water intaking valve on delivery port and the cleaning outlet valve on water inlet are opened, rinse water carries out back flush sintered meshwork or sintering felt from water outlet end with uniform pressure, rinse water flows out from water inlet, to reach the object of reverse cleaning metal screen, cleaning in the other direction can after each water intaking, according to water withdrawal setting scavenging period self-cleaning, cleaning process was only for tens seconds, rinse water adopts the water purification after filtering or running water to carry out cleaning, utilize the impurities left on the principle cleaning sintered meshwork of flushing in the other direction, reach the permanent object used, greatly reduce production cost, user does not often need more renew cartridge can reach good production effect.
In the present invention, can also fixed time cleaning be adopted, equipment arranges button, control cleaning function, according to different quality setting cleaning frequency.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
