Problems solved by technology
However, although this invention solves the problem of water stop when replacing and disassembling the filter element, the technical solution has a complex structure and many materials, so the manufacturing cost is high; in addition, it also has the same defects as the existing RO membrane filter, The remaining water after treatment adopts an unscientific short-circuit output mode; in view of the above-mentioned shortcomings, the present invention provides the society with a single-layer water inlet and water stop mechanism, scientific and reasonable water passages, compact layout, simple structure, and small volume. , Sealed and reliable quick connection three-way RO membrane filter connection mechanism, which brings convenience to the production of enterprises and the daily life of users

Embodiment Construction
[0049] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0050] like figure 1 , figure 2 As shown, the upper part of the quick docking joint (5) is provided with symmetrical double-slope projections (43) that are interlocked with the quick docking cover (2).
[0051] like figure 1 , figure 2 As shown, at the position below the double-slope bulge (43) aligned with the spool stem (19), there are symmetrical right double-slope spool stem drive projections (7) and left double-slope valve The mandrel drives the lug (13).
[0052] like figure 1 , figure 2 As shown, the shapes of the above-mentioned double-slope bump (43), right double-slope spool rod driving bump (7) and left double-slope spool rod driving bump (13) are all inclined-plane structures with protruding front ends. The oblique block on the circumference of the body; the oblique block has the function of locking the quick docking joint (5) and the quick dock...

The invention belongs to the field of water purifier, and particular relates to a quick-connection three-way RO(reverse osmosis membrane) filter connecting mechanism which is provided with a quick connector and a quick connector cover. Double-bevel protrusions for controlling on and off of check valves are arranged on two sides of the quick connector. A pure water passage, a source water feeding passage, a residual water discharging passage and a batcher seat are respectively arranged at the center, on the two sides and at the back of the upper portion of the quick connector cover. The residual water discharging passage is connected with a batcher. In mounting of a filter, the double-bevel protrusions act on tails of valve spools of the check valves; once the check valves are switched on, a cover is combined with the quick connector cover, the source water feeding passage and the residual water discharging passage are opened, and the filter is in a working state; in processes of changing, assembling and detecting the filter element and detaching a filter cartridge, the double-bevel protrusions are released, the check valves on the left and right sides are reset, the source water feeding passage and the residual water discharging passage are closed, so that the filter element is changed, assembled and detected on a water-stop condition, and product assembly and detection are facilitated for users.
Description
technical field [0001] The invention belongs to the field of household water purifiers, in particular to a fast connection mechanism for a three-way RO membrane filter. Background technique [0002] In the daily use of water purifiers, it is very common to clean and replace the filter element. However, the operation of disassembling the filter element is a professional operation, and the disassembly operation must be carried out under the condition of water stop. Therefore, inventing a filter that can automatically stop water when cleaning and replacing the filter element is a preferred technical solution; patent: 20132017242.1, patent name: one-way valve for water purification filter and water purification filter, Disclosed is a vertical and horizontal structure and a technology for water-stopping measures for water passages arranged in multiple layers. However, although this invention solves the problem of water stop when replacing and disassembling the filter element, th...
