Method for forming connected filter chambers and channels by butt joint of water purifier dual-row filter cartridges and engine bases

Abstract

The invention discloses relates to the water treatment industry, particularly relates to the filtration of drinking water, and discloses a method for forming connected filter chambers and channels by butt joint of water purifier dual-row filter cartridges and engine bases. The connected filter chambers and channels comprise injection molding cartridge bodies with movable covers and seal elements and injection molding engine bases with water passing pipelines; the injection molding cylinder bodies, in which built-in filtering containers are arranged, are of structures bigger in upper part and smaller in lower part; the sealed butt joint parts arranged on the injection molding engine bases are corresponding to the bottom parts of dual-row multi-cavity injection molding cartridge bodies; connected filter cartridges, which are formed by butt joint in a sealed mode by a plastic welding connection technology or a bonding agent bonding technology, are bigger in upper part and smaller in lower part and are connected with the engine base; the connected filter cartridges and the movable covers as well as the seal elements form a plurality of connected seal cavities bigger in upper part and smaller in lower part; a space is reserved in the periphery of the lower part of each cartridge body; each water passing pipeline of the injection molding bases is connected with each filter cartridge in series by correspondingly arranged sealed chamber water passing interfaces so as to form filter channels which are respectively connected with a water inlet and a water outlet of each internally arranged filter cartridge in series, wherein at least one water passing interface is positioned in the sealed butt joint parts of the engine bases and is in butt joint in a sealed mode with water openings with seal elements on the lower end surfaces of the internally arranged filter containers.

Problems solved by technology

[0002] At present, the water purifier adopts the structure of lower machine base, single-row three-cavity conjoined body and upper split screw cap, on the basis of retaining the low-cost built-in filter gall of the traditional open filter cavity structure water purifier, and adopts movable upper The cover and the built-in filter gallbladder mode have the advantages of labor-saving, convenient, and not easy to overflow, etc. It overcomes the difficulty of opening the cavity to replace the built-in filter gallbladder of the traditional open-type filter cavity structure water purifier, easy water overflow, unstable component assembly quality, low efficiency, Defects and deficiencies such as high labor intensity

However, the water purifier adopting the lower machine base, the single-row three-cavity conjoined body and the upper-set split screw cap structure produces new problems: in view of the diameter of the filter cartridge of the open filter cavity is much larger than the diameter of the closed filter gall, in addition, each A corresponding gap needs to be left between the filter cartridges to facilitate the opening of the separate screw caps, so it is impossible to set more filter chambers within a limited length like a water purifier with a closed filter gall

But at the same time, it also leads to a more complicated structure of the double-row conjoined filter cartridge

In particular, the setting of the upper cover makes the size of the upper port of each filter cartridge larger. In addition, the inner cavity of the filter cartridge needs to be set with a large upper and a lower draft taper, uniform cylinder wall and other injection molding process requirements, so that the one-piece filter cartridge The outer side has a structure with a small bottom and a large top, and the lower part of the filter cartridge is connected to the machine base, which makes it impossible to use the single-row one-piece filter cartridge split mold for demoulding mode, and can only increase the external size of the lower part of the cylinder to make it appear "" On the basis of "lower big and upper small", demoulding along the axis of the filter cartridge upwards, but this will increase the excess weight of the filter cartridge, significantly increase the manufacturing cost of the one-piece filter cartridge, and cause unnecessary waste that does not meet the "low-carbon" requirements

Even without considering the uniformity of the cylinder wall, it is difficult to realize the multi-directional core-pulling demoulding injection molding process, and the efficiency is extremely low.

[0003] The patent application materials with the Chinese patent application number 201210137668.1 disclose a number of technical solutions that use multiple single filter cartridges and machine bases to form a double-row conjoined filter cavity, including standard parts and pressure plate connection modes, thread spin The connection mode of the connection and the threaded sleeve, and the connection mode of the internal buckle, but they all require a relatively complicated and cumbersome connection structure, locking structure, and sealing structure set on the connection filter cartridge and the machine base, and seal the two parts with a seal. At the place, the structure of the filter cartridge and the machine base is relatively complicated, and the reinforcement structure is added around the joint, resulting in an increase in the weight and cost of the components

Especially for the use of rigid pipeline open groove bases to form assembled machine bases through the cooperation of standard fasteners, cover plates, and gaskets. In addition to the above-mentioned problems, it is easy to cause poor sealing of plane laying pipeline open grooves in addition to the above-mentioned problems. Strict cross-talk

The above-mentioned defects and deficiencies directly affect the promotion and use of the double-row conjoined filter cartridge structure of the water purifier
