Description

A New Type of Reverse Osmosis Household Water Purifier

technical field

The utility model relates to a water purifier. In particular, it relates to a novel reverse osmosis household water purifier.

Background technique

With the improvement of residents' living standards, more and more families have begun to use household water purifiers, of which there are two mainstream technologies: ultrafiltration and reverse osmosis. There are generally two problems in the design of reverse osmosis household water purifiers. One is that the produced water is acidic, and drinking acidic purified water for a long time is not conducive to human health. The other is that the produced water needs to be stored in the water storage tank first, and the pure water in the water storage tank passes through the faucet for people to drink. Professional cleaning inside will cause the growth of bacteria, the purified water will be polluted twice, and the water quality will be reduced. Under such circumstances, drinking such water directly will threaten human health and pose a very large safety hazard.

Contents of the invention

The technical problem to be solved by the utility model is to provide a novel reverse osmosis household water purifier capable of adjusting pH and retaining regeneration bacteria.

The technical solution adopted by the utility model is: a new type of reverse osmosis household water purifier, including a pretreatment unit, a high-pressure pump and an advanced treatment unit connected in sequence through pipelines, and the pretreatment unit is composed of PP filter element, granular activated carbon filter element and compressed activated carbon filter element, the water inlet end of the PP filter element is connected to the municipal tap water inlet, the water outlet end of the compressed activated carbon filter element is connected to the water inlet end of the high-pressure pump through a pipeline, and the advanced treatment unit It is composed of a reverse osmosis membrane filter element, the water outlet end of the reverse osmosis membrane filter element is respectively connected to the concentrated water inlet end and the water inlet of the water storage tank, and the water outlet of the water storage tank is passed through a post that can adjust pH and intercept regenerative bacteria Disposal unit to water tap.

The post-processing unit includes a connected alkalization ball filter element and a PVDF ultrafiltration membrane filter element, the water inlet end of the alkalization ball filter element is connected to the water outlet of the water storage tank, and the water outlet end of the PVDF ultrafiltration membrane filter element is connected to Take the tap.

A low pressure switch is arranged on the pipeline between the compressed activated carbon filter element and the high pressure pump.

A high-pressure switch is arranged on the pipeline between the high-pressure pump and the reverse osmosis membrane filter element.

The utility model provides a novel reverse osmosis domestic water purifier, which can correct the shortcomings and hidden dangers of the existing reverse osmosis water purifier while retaining the advantages of the existing reverse osmosis water purifier. The weakly alkaline water produced is closer to the pH of human body fluids, and long-term drinking is good for health. The utility model can minimize the risk of bacteria breeding due to the long-term storage of pure water in the water storage tank and the lack of professional cleaning of the inside of the water tank by setting the PVDF ultrafiltration filter element. The alkalization ball filter element of the utility model adopts an integrated design and needs to be replaced as a whole; the ultrafiltration filter element adopts a shell-core separation design, and the filter element can be replaced separately, which is more economical.

detailed description

A new type of reverse osmosis household water purifier of the present utility model will be described in detail below in conjunction with the embodiments and accompanying drawings.

A new type of reverse osmosis household water purifier of the utility model is based on the design of mainstream water purifiers in the market, adding an alkali particle filter element and a rear PVDF ultrafiltration filter element to achieve the effect of adjusting pH and retaining regenerative bacteria, ensuring People's drinking water is safe.

As shown in Figure 1, a new type of reverse osmosis household water purifier of the present utility model includes a pretreatment unit, a high-pressure pump 5 and an advanced treatment unit connected in sequence through pipelines, and the pretreatment unit is sequentially connected in series A PP filter element 1, a granular activated carbon filter element 2 and a compressed activated carbon filter element 3 are formed. The water inlet end of the PP filter element 1 is connected to the water inlet 13 of municipal tap water, and the water outlet end of the compressed activated carbon filter element 3 is connected to the inlet of the high-pressure pump 5 through a pipeline. The water end, the advanced treatment unit is composed of a reverse osmosis membrane filter element 7, the water outlet end of the reverse osmosis membrane filter element 7 is respectively connected to the concentrated water inlet end 12 and the water inlet of the water storage tank 8, and the water storage tank 8 The outlet of the water passes through the post-treatment unit capable of adjusting the pH and retaining the regenerated bacteria to the water tap 11.

Described aftertreatment unit comprises the connected alkalization ball filter element 9 and PVDF ultrafiltration membrane filter element 10, and the water inlet end of described alkalization ball filter element 9 connects the water outlet of described water storage tank 8, and described PVDF ultrafiltration membrane filter element The water outlet of 10 is connected with water tap 11.

A low pressure switch 4 is arranged on the pipeline between the compressed activated carbon filter element 3 and the high pressure pump 5 .

A high pressure switch 6 is arranged on the pipeline between the high pressure pump 5 and the reverse osmosis membrane filter element 7 .

A new type of reverse osmosis household water purifier of the present utility model, on the basis of the original pressure of the municipal tap water, first removes large particles of mechanical impurities in the water through the PP filter element 1 in the pretreatment unit, and then absorbs the residual water in the water through the granular activated carbon filter element 2 Chlorine, pesticides and other substances, and then pass through the compressed activated carbon filter element 3 to remove odors and heavy metals in the water.
