As shown in fig. 3-12, the utility model provides a triplet lid of quick fixed lauter tub, will install two in triplet lid 4's inside water service pipe 404 earlier and block up 401 and 402 before installation filter core and lauter tub C, divide into the three-section to this kind of integral type water service pipe through increasing two blockings in water service pipe 404 to realize with the business turn over water interface assorted mesh of one, two, tertiary filter core, improved the antiknock performance of water purifier. In addition, for the 401 or 402 plug, the pressure of the water inlet contact surface and the pressure of the water outlet contact surface are almost equal, so the plug cannot be washed loose by water flow after being assembled in a pipeline, the phenomenon of water leakage or water leakage cannot occur easily, and the product with the structure has high reliability.

Further, as shown in fig. 4 and 7, the triple cover 4 is divided into three parts, namely a first-stage water filtering unit 410, a second-stage water filtering unit 411 and a third-stage water filtering unit 412, from two dotted lines, and each part is provided with an internal thread 405 for fixing a filter vat in a corresponding position; a cartridge water-seal 406 for separating the water before and after filtration by the cartridge; a central positioning post 407 for positioning the filter element to center and for guiding out the water purified by the filter element; in order to enhance the strength of the triplet cover 4 and improve the anti-explosion performance of the triplet cover, reinforcing

ribs

408 and 409 are additionally arranged between the two adjacent parts; in addition, a plane 413 which is attached to a side sealing ring C01 of the filter barrel C is designed; the plane 414 attached to the top surface sealing ring C02 of the filtering barrel C has double sealing effect, and can prevent water leakage due to untight matching between the filtering barrel C and the triplet cover 4. During water making, water flows in from the left water inlet 418 and flows out from the right water outlet 419; the water inlet 418 and the water outlet 419 are linearly distributed and are provided with internal thread structures for connecting a water conduit; the first-stage water filtering unit 410, the second-stage water filtering unit 411 and the third-stage water filtering unit 412 are respectively provided with a

through hole

415, 416 and 417 which are communicated with the main water pipeline 404 and the lower cavity of the triple cover 4.

As shown in fig. 8 and 9, the

plugs

401 and 402 may be circular, square or other shapes, preferably circular, as the water passage 404 of the triplet cover 4. In order to ensure reliable water sealing of the plug, the two

plugs

401 and 402 are loaded to the corresponding position of the main water pipeline 404 by quickly pressing down the arrow direction in fig. 8 by a tool fixture when the triplet cover 4 is demoulded for no more than 10 seconds and is not completely cooled during injection molding, so that the plugs can be well fixed in the water pipeline 404 and can be sealed after the triplet cover 4 is cooled and shrunk.

The working process of the triplet cover of the rapid fixing filter barrel and the flow direction of water are as follows:

as can be seen from the cross-sectional view of the filter vat in FIG. 10, the bottom of the filter vat also has a water sealing post C03 and a cartridge positioning post C04; the water sealing column C03 is used for sealing the lower part of the filter element; the filter element positioning column C04 is used for positioning the lower part of the filter element; the upper part of the filter barrel C is also provided with an external thread C05 matched with the triplet cover 4. When the filter element and the filter barrel C are arranged on the triplet cover 4, the filter can be connected to a tap water waterway for use.

The working principle is as follows: raw water firstly enters from a water inlet 418 at the left end of a water pipeline 404 in the figure 11 → flows to a plug 401 and is blocked, then flows into an interlayer space formed by a first filter barrel and a filter element at the left side from a communicating hole 415 → flows through a central positioning column 407 of a first-stage water filtering unit 410 of a triplet end cover from a central hole of a first-stage filter element after being filtered by the first-stage filter element → returns to the left side of the middle section of the water pipeline 404 again → then flows into a space formed by a middle filter barrel and a second-stage filter element from a communicating hole 416 → flows through a central positioning column 407 of a second-stage water filtering unit 411 of the triplet end cover from a central hole of the second-stage filter element after being filtered by the second-stage filter element and returns to the right side of the middle section of the water pipeline 404 through a central positioning column 407 of a second-stage water filtering unit 411 of the triplet end cover from a communicating hole 417 after being filtered by the third-stage filter element Thus, the three-stage filtration of water can be finished.

The triplet cover of the rapid fixed filter barrel in the utility model is integrated, so that the A/B pair wires shown in figure 1 are not used between the two end covers to connect, thereby reducing the connectors of the product and reducing the risk of water leakage; and because no butt thread is used between the end covers, a raw material belt cannot be used at the position, so that the material cost and the installation difficulty during the production of the product are reduced.

The utility model designs a pressure relief hole 403 on the right side of the middle cover of the triplet cover 4, the inner side of the hole is communicated with the water path inside the triplet cover 4, and the outer side is communicated with the atmosphere; the opening and closing of the aperture is controlled by connecting a pressure relief valve to the outside of the aperture. The valve connected with the hole is closed at ordinary times, when the filter element needs to be replaced, residual pressure in the water purifier can be released only by pressing the handle of the valve, and the filter barrel is screwed after pressure release, so that the filter barrel is easier to release than before pressure release.

The utility model discloses a concrete example is applied to explain the principle and the implementation mode of the utility model, and the explanation of the above example is only used to help understand the method and the core idea of the utility model; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
