Water purification machine

Abstract

A water purification machine is disclosed. The water purification machine comprises a shell, a filtering system, a booster pump, a water inlet magnetic valve, a wastewater magnetic valve, and the like, wherein the filtering system, the booster pump, the water inlet magnetic valve, the wastewater magnetic valve, and the like are arranged in the shell. The water purification machine is characterized in that: the filtering system comprises a front polypropylene (PP) filter core, a composite filter core and back filter cores; the composite filter core comprises a filter shell; a filtering material of a coarse filtering system and a reverse osmosis (RO) membrane filtering material of a fine filtering system are sequentially sleeved and packaged in the filter shell from outside to inside; and a source water inlet, a concentrated water outlet and a pure water outlet which are communicated with corresponding connecting pipes are formed in the bottom of the filter shell. Various levels of filtering materials are integrated and packaged in the composite filter core, so that the cost of plastic parts and the space occupied by the filter core are largely reduced, connectors and polyethylene (PE) pipes which are used for connecting the filter cores are also not needed, and the material cost and the labor cost are reduced. In addition, internal connectors are reduced, so that the error of water leakage is largely reduced. The water purification machine is simple and reasonable in structural layout, small in occupied space, low in cost, simple in production process, reliable in sealing performance and convenient to maintain and replace.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pure water machine with simple and reasonable structural layout, small occupied space, low cost and good sealing performance. Background technique [0002] With the continuous deterioration of the ecological environment, the crisis of fresh water resources for human survival has become increasingly prominent. In order to solve the problem of healthy drinking water, various drinking water devices have been born on the market in recent years, which better solve the problem of drinking water in homes and various indoor places. problem. The working principle of the existing household pure water machine is to pressurize the source water and then perform coarse filtration by PP filter element, UDF filter element, CTO filter element, etc., and then deeply separate into pure water and concentrated water through RO reverse osmosis membrane, and the pure water enters the storage ...

AI Technical Summary

Problems solved by technology

The filtration system generally includes a coarse filtration system and a fine filtration system. The filter materials of the coarse filtration system include PP cotton, activated carbon, ceramics, etc., and various filter materials are respectively packed in a plastic cylinder; the fine filtration system is mainly RO reverse osmosis membrane, which is also installed In a plastic cylinder, all kinds of filter materials are individually packaged through the plastic cylinder, and then the filter elements of all levels are connected in series with quick connectors and PE pipes. This traditional combination of filter elements not only occupies a large internal space of the machine, There are many consumables, cumbersome production process, many interfaces, high risk of water leakage, high production cost and after-sales maintenance cost
