Embodiment 1
[0028] Example 1. A method for fastening and connecting a booster pump of a water purifier with an upper and a lower double-layer structure, in which a plurality of filter galls 7 including a pre-filter and a reverse osmosis membrane filter are connected in series and a booster The pump 26 constitutes a filter channel, wherein the part corresponding to the pre-filter gallbladder 7a, 7b, 7c is a pre-filter channel, and the inlet and outlet pipes 34, 33 of the booster pump 26 are respectively connected to the rear end of the pre-filter channel and the reverse osmosis membrane The water inlet 7d1 of the filter gallbladder 7d; the reverse osmosis membrane filter gallbladder pure water port 7d2 is connected to the pure water pipeline, and the concentrated water discharge pipeline connected to the reverse osmosis membrane filter gallbladder drain outlet 7d3 is provided with a concentrated water discharge flow control device 6; The module 20 is used as a base for connecting the rear ...
Embodiment 2
[0033] Example 2. On the basis of Embodiment 1, the upper module is provided with a wire connection to the electric control device and a downward upper pair of contact point structures; The contact point structure corresponds to and connects the booster pump 26 control end with wires; the lower contact point structure is either arranged on the upper end surface of the bracket structure or on the upper end surface of the frame structure, wherein:
[0034] When the lower contact point structure is arranged on the upper end surface of the support structure, the lower contact point structure located on the upper end surface of the support structure is docked with the upper contact point structure of the upper module, and at the same time, the lower butt joint nozzle on the upper end surface of the frame structure passes through the frame window and The upper butt joint nozzle of the upper module is sealed butt joint.
[0035] For the mode (not shown) that the lower pair of contac...
Embodiment 3
[0041]Example 3. On the basis of Embodiments 1 and 2, the frame structure includes an upper pressure structure with a lower butt contact point structure, a lower butt joint nozzle and a fastening standard fitting structure, and a lower pressing structure with a corresponding fastening standard fitting fitting structure. Structure; the upper and lower pressure structures are respectively located on the upper and lower sides of the pump head part where the inlet and outlet booster pumps are installed, and the pump head part is clamped and integrated by fastening standard parts; the upper pressure structure is fixed by fastening standard parts It is hoisted and fixed below the bracket structure; in addition, triple shock absorbers are installed: the pump head shock absorbers are installed between the upper and lower pressure structures and the pump head part; the upper pressure structure and the bracket structure are installed and installed Shock absorbing parts; fastening shock ...
