The invention discloses a pipeline connection method of a vertical pipeline base of a water purifier with a U-shaped cavity. A box-type base with an upward cavity opening used for placing filter containers is arranged; a water passing pipeline is connected with the filter containers and a water passing control part to form a filter channel; a vertical pipeline machine base provided with a transverse pipeline water gap and a downward pipeline connector and is communicated with the transverse pipeline water gap and the downward pipeline connector, and the U-shaped cavity provided with a transverse rigid pipeline at the bottom are also arranged; a transverse pipeline water opening of the vertical pipeline machine base is in sealed butt joint with the water passing control part; and one end, provided with the transverse rigid pipeline, of the bottom of the U-shaped cavity extends to the bottom of a facility cavity, is provided with a vertically upward pipeline interface, is hermetically butted with a downward pipeline interface of the vertical pipeline base to form a movably butted water passing pipeline in the filtering channel, and respectively communicates a downward water openings of the filter containers with a related water opening of the water passing control part arranged on the vertical assembly pipeline machine base.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] A water purifier with an upper module and a box-type base has the advantages of control display, self-replacement of the filter tube and convenient maintenance, especially the space between the box-type base cavity wall and the built-in filter tube can be used as the machine shell Structural storage Concentrated water constitutes a concentrated water storage chamber to facilitate the use of concentrated water reuse technology in small-sized machine environments. However, since the upper operating surface and the central core position of the machine are used for the setting of the above-mentioned basic functions, in the limited space structure range of the machine size of about 500mm×200mm×460mm, surrounding the setting position of the booster pump, connecting the filter gall Fixed stru...

Problems solved by technology

However, since the upper operating surface and the central core position of the machine are used for the setting of the above-mentioned basic functions, in the limited space structure range of the machine size of about 500mm×200mm×460mm, surrounding the setting position of the booster pump, connecting the filter gall Fixed structure mode, related pipeline connections, booster pump circuit control, pipeline and water storage structure settings of the concentrated water reuse system, filter gallbladder fixed structure of related water passing control components, convenient connection of pipelines, and equipment for the machine Some ad hoc functions such as pure and purified water double outlet technology, concentrated water quality monitoring and reuse technology, filter life dynamic detection and prompt technology, filter gallbladder recoil cleaning technology, machine remote automatic control detection technology, upper and lower dual The application of the joint device between the layer structures and the convenient mobile structure setting of the machine make the setting and installation of the relevant water control components and structures of the machine, especially the fastening and installation of the booster pump with large volume and weight and frequent operation. Connecting and repairing raises new questions

Secondly, the gallbladder chamber needs to place multiple gallbladders and store concentrated water, and the wall of the chamber is relatively thin but bears most of the weight of the machine. The shape requirements should not adopt the mode of setting reinforcement ribs on the outside, and it is not suitable to set a transverse reinforcement structure on the inside (difficult to remove the film), resulting in low rigidity of the box-type machine base, easy deformation or even damage

Third, since the main positions of the machine are used for the loading and unloading of the filter gallbladder and the control and display interface, the water-passing pipeline and the connected water-passing control components as the filter channel can only be scattered and arranged using the gaps between the components, resulting in " As a semi-finished product, the water purifier is always inseparable from the dilemma of after-sales maintenance service network, and can only be repaired by professional maintenance personnel

Fourth, for the box-type machine base, a conjoined double-chamber mode consisting of a filter cavity specially equipped with a water storage function and a facility cavity for placing water-passing control components is adopted. In order to meet the requirements of injection molding, the outer facade of the box-type machine base should be as vertical as possible. The extremely small mold draft angle leads to the existing mold demoulding problem, and the existence of the partition separating the two cavities makes the demoulding of the gallbladder cavity and the facility cavity more difficult

In addition, for the box-type machine base with the gallbladder chamber facing upward and the facility chamber facing downward, although it has the advantage of easy demoulding, due to the influence of demoulding during the injection molding process, it is difficult to pass the injection molding method near the port of the facility cavity. The installation seat structure is set, and then the connection structure of the cavity bottom cover is a cantilever beam structure, which leads to poor force bearing, especially when the heavy booster pump is placed, it is easy to shake during operation, and an auxiliary structure (fulcrum) needs to be equipped. Whether the connection between the structure and the side wall of the facility cavity (usually by bonding) is firm and affects the assembly efficiency

The above-mentioned defects and deficiencies make it difficult for the above-mentioned concentrated water storage chamber mode to be widely used in water purifiers
