in operation, since the micropores remain closed when no pressure exists in the expansion chamber 71, after the tap water to be filtered enters the expansion chamber 71 in the rubber block 7 through the water inlet 14, the tap water to be filtered fills the expansion chamber 71 and expands the expansion chamber 71, then the pressure in the expansion chamber 71 increases to the extent that the micropores are opened, the tap water in the expansion chamber 71 flows out from the micropores into the housing 3 to start filtering, and at the same time, after the expansion chamber 71 is subjected to the action of the tap water to be filtered entering the interior, the expansion is started firstly because the thickness of the expansion chamber 71 close to the side wall of the filter layer 6 is thinner, after the expansion of the expansion chamber 71, the part of the rubber block 7 facing the filter layer 6 begins to expand, further contact and extrusion cardboard 5, carry out secondary restriction and fixed cardboard 5, avoid cardboard 5 to install and appear not hard up after the mounting panel 4, influence the hugging closely between filter layer 6 and the mounting panel 4, lead to appearing the gap between filter layer 6 and the mounting panel 4, cause unfiltered running water to enter into and collect in the chamber 42, influence final filter effect, simultaneously, restriction and the fixed cardboard 5 through inflation, convex rubber piece 7, can further avoid at the filtration in-process, cardboard 5, filter layer 6 receive the influence of the water pressure of waiting filtered running water, lead to cardboard 5 to appear lax between one end that is close to base 1 and the mounting panel 4, lead to unfiltered running water to enter into and collect in the chamber 42, influence the filter effect of compound filter core to running water.
As one embodiment of the present invention, the mounting plate 4 is made of stainless steel material; the base 1 and the housing 3 are made of plastic material;
during operation, through using stainless steel material to make mounting panel 4, can guarantee that mounting panel 4 has good intensity, avoid in production, the installation, deformation, distortion appear in mounting panel 4, lead to cardboard 5 can not normally block to mounting panel 4, make the gap appear between cardboard 5 and the mounting panel 4, finally make lie in between cardboard 5 and the mounting panel 4 filter layer 6 can not hug closely on mounting panel 4, cause unfiltered running water to enter into in collecting chamber 42 from the gap between filter layer 6 and mounting panel 4, influence the filter effect of compound filter core, simultaneously, in compound filter core use, through the mounting panel 4 of stainless steel material preparation, can effectually resist the inside water pressure that exists of filtering the in-process, avoid mounting panel 4 to receive the effect of water pressure, appear deforming and influence the normal use of mounting panel 4, lead to the filter effect of compound filter core not good.
As an embodiment of the present invention, the side surface of the fixing post 2 is provided with a micro groove 21, and the length direction of the micro groove 21 is the same as the length direction of the fixing post 2; the micro grooves 21 are distributed uniformly around the central line of the fixed column 2; the fixed column 2 has magnetism, and the fixed column 2 is a permanent magnet;
during operation, as the fixed column 2 has magnetism, the metal particles contained in tap water to be filtered entering the composite filter element are influenced by the magnetic force of the fixed column 2 and are adsorbed to the fixed column 2 to be fixed, the possibility that external metal particles still move and are attached to the filter layer 6 after entering the composite filter element is reduced, the filtering effect of the filter layer 6 is improved, meanwhile, the metal particles existing in the space in the composite filter element are prevented from diffusing everywhere, the filtering effect and the service life of the filter layer 6 are influenced, and meanwhile, the micro grooves 21 formed in the surface of the fixed column 2 can effectively increase the surface area of the fixed column 2, the metal particles adsorbed by the fixed column 2 are stored in the micro grooves 21, and the possibility that the metal particles are dissociated again is reduced.
A composite filter element ultrafiltration water purifier, wherein the composite filter element in the ultrafiltration water purifier is one of the composite filter elements.
The specific working procedure is as follows:
during operation, tap water to be filtered is introduced into the composite filter element from the water inlet 14, then purified water after filtration in the filter element is discharged from the water outlet 13 on the filter element, meanwhile, tap water to be filtered enters the composite filter element from the water inlet 14, then directly enters the space in the shell 3 through the water inlet 14 passing through the base 1, then sequentially passes through the through holes on the clamping plate 5, the filter layer 6 and the mesh 41 on the mounting plate 4 under the action of external pressure to enter the collecting cavity 42 in the mounting plate 4, filtration is completed, then, filtered purified water entering the collecting cavity 42 enters the collecting cavity 11 in the base 1 through the communication hole 12, finally, discharged from the water outlet 13 communicated to the collecting cavity 11, and meanwhile, the projection of the mounting plate 4 on the base 1 is spiral, so that the surface area of the mounting plate 4 is relatively large, the surface area of the filter layer 6 is further larger, the volume of water passing through which is contacted and contacted in unit time of the filter layer 6 is larger, the filtration speed of the composite filter element is improved, meanwhile, the filtered tap water in the PP cotton layer 61 in the filter layer is firstly contacted with the large volume of the filter layer 6, and the active carbon layer is simultaneously removed by the filter layer 63, and the active carbon is simultaneously, and the impurities in the filter layer is further removed; after the clamping plate 5 is mounted on the mounting plate 4, one end, close to the base 1, of the clamping plate 5 contacts and presses the rubber block 7, and an opening, close to the base 1, of the clamping plate 5 is fixed through the rubber block 7; after the tap water to be filtered enters the expansion cavity 71 in the rubber block 7 through the water inlet 14, the tap water to be filtered fills the expansion cavity 71 first, the expansion cavity 71 is expanded, then the pressure in the expansion cavity 71 is increased to the extent that the micropores are opened, the tap water in the expansion cavity 71 flows out of the micropores into the shell 3 to start filtering, meanwhile, after the expansion cavity 71 is expanded under the action of the tap water to be filtered entering the expansion cavity, the expansion cavity 71 is thinner near the side wall of the filter layer 6, so that after the expansion cavity 71 is expanded, the part of the rubber block 7 facing the filter layer 6 is expanded first, and further contacts and presses the clamping plate 5 to secondarily limit and fix the clamping plate 5; the mounting plate 4 is made of stainless steel materials, so that the mounting plate 4 is guaranteed to have good strength; because the fixed column 2 has magnetism, the metal particles contained in the tap water to be filtered entering the composite filter element are influenced by the magnetic force of the fixed column 2 and adsorbed on the fixed column 2 for fixing, and meanwhile, the micro-groove 21 arranged on the surface of the fixed column 2 can effectively increase the surface area of the fixed column 2, and the metal particles adsorbed by the fixed column 2 are stored in the micro-groove 21.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
