detailed description

This embodiment proposes a water purifier with a simple structure, which can effectively purify tap water and ensure that the purified water obtained after purification is safe and rich in nutrients. Fig. 1 is a schematic diagram of the external connection structure of a water purifier 100 according to an embodiment of the present invention. As shown in FIG. 1 , the water inlet 101 of the water purifier is connected to an external tap water outlet 200 , and the water outlet 102 of the water purifier is connected to a valve 300 . One or more filter modules provided inside the water purifier 100 can effectively filter harmful substances such as sediment, rust, heavy metals, bacteria, etc. in the tap water, and can also retain minerals to provide people with safe and nutritious purified water, thereby Ensure people's health. The valve 300 can be a faucet, and the flow of the purified water is controlled by opening and closing the faucet, making the process of using the purified water easier and more convenient for the user. In addition, the external connection structure of the entire water purifier 100 is very simple, and there are few joints, which can effectively reduce the risk of water leakage.

Fig. 2 is a schematic diagram of the internal connection structure of the water purifier 100 according to an embodiment of the present invention. As shown in FIG. 2 , the water purifier 100 may generally include: a coarse filtration module 10 , a heavy metal removal module 20 and an ultrafiltration module 30 .

Coarse filtration module 10, its water inlet 11 is connected with the water inlet 101 of water purifier, to remove the large particle impurity in tap water; Heavy metal removal module 20, its water inlet 21 is connected with the water outlet 12 of coarse filtration module 10 , the heavy metal removal module 20 includes a chelating resin filter element to absorb heavy metal ions in tap water; the ultrafiltration module 30, its water inlet 31 is connected to the water outlet 22 of the heavy metal removal module 20, to filter out bacteria in the tap water and obtain purification water. The water outlet 32 of the ultrafiltration module 30 is connected to the water outlet 102 of the water purifier to provide purified purified water.

Wherein, the coarse filtration module 10, the heavy metal removal module 20, and the ultrafiltration module 30 may include, in addition to the respective filter elements for filtering tap water, containers for accommodating their respective filter elements. In this case, the coarse filtration module 10, the heavy metal removal module 20, and the ultrafiltration module The filter modules 30 can be connected by pipelines. In some other embodiments, the coarse filtration module 10 , the heavy metal removal module 20 and the ultrafiltration module 30 may also be directly connected through respective filter elements.

The three filter modules inside the water purifier 100 are arranged in sequence according to the order of the coarse filter module 10 , the heavy metal removal module 20 , and the ultrafiltration module 30 . impurities in the water; then the heavy metal ions in the water are adsorbed by the chelating resin filter element of the heavy metal removal module 20; finally, the bacteria in the water are filtered by the ultrafiltration module 30. The method of purifying tap water is more scientific, and only three modules can be used to obtain safe and nutritious drinking water for mothers and infants. In addition, the coarse filtration module 10 , the heavy metal removal module 20 , and the ultrafiltration module 30 can be arranged in sequence from top to bottom, or from left to right in sequence.

The heavy metal removal module 20 is detachably connected with the coarse filtration module 10 and the ultrafiltration module 30, so as to be replaced after the chelating resin filter core is saturated with adsorbed heavy metal ions. After the chelating resin absorbs heavy metal ions and is saturated, it can be considered that the chelating resin has reached its service life. The chelating resin filter element is disassembled and discarded, and it can continue to be used after a new filter element is replaced. The process of maintaining and updating the filter element is simple and convenient, effectively saving the cost of water purification .

In a preferred embodiment, the coarse filtration module 10 includes a polypropylene fiber filter element or a pleated filter element; the heavy metal removal module 20 includes a chelating resin filter element; and the ultrafiltration module 30 includes an ultrafiltration membrane.

Among them, the polypropylene fiber filter element, also known as "PP cotton filter element", is a tubular filter element made of non-toxic and tasteless polypropylene particles, which are heated and melted, sprayed, drawn, and formed. The polypropylene fiber filter element can effectively remove various particles and impurities in tap water; as a multi-layer deep structure, it has a large amount of dirt; the filtration flow rate is large and the pressure difference is small; it does not contain any chemical adhesives, which is more hygienic and safe; , deep layer, coarse and fine filtration are integrated, effectively reducing the cost of filtration. Polypropylene pleated filter element is an advanced fixed depth filter element with filtration accuracy ranging from 0.1μm to 60μm. The filter membrane of the polypropylene pleated filter element will not affect the filtration accuracy due to pressure fluctuations, and has the characteristics of low pressure difference, high flux, good filtration accuracy and low economic cost.

The heavy metal removal module 20 uses a chelating resin filter element to absorb heavy metal ions in tap water, because the chelating resin is a type of cross-linked functional polymer material that can form multi-coordination complexes with heavy metal ions. The mechanism of chelating resin to adsorb heavy metal ions is that the functional atoms on the resin undergo a coordination reaction with heavy metal ions to form a stable structure similar to small molecular chelates. The mechanism of ion exchange resin adsorption of heavy metal ions is electrostatic interaction. Compared with ion exchange resins, chelating resins have a stronger binding force with heavy metal ions, and the effect of adsorbing heavy metal ions to purify tap water is also better.

Ultrafiltration membrane is a microporous filtration membrane with consistent pore size and rated pore size ranging from 0.001 to 0.02 μm. The ultrafiltration membrane is driven by the pressure difference on both sides of the membrane. When tap water flows through its surface, its pore size only allows water molecules, beneficial minerals and trace elements in the water to pass through, and the volume of the smallest bacteria is above 0.02 microns. Therefore, the bacteria can be intercepted by the ultrafiltration membrane, so that the process of filtering bacteria in tap water can be realized.

The water purifier 100 of the present embodiment purifies tap water by sequentially arranging the coarse filtration module 10, the heavy metal removal module 20, and the ultrafiltration module 30, and can remove harmful substances such as sediment, rust, heavy metals, bacteria, etc. Substances provide people with safe and nutritious purified water to ensure people's health. Wherein the heavy metal removal module 20 comprises a chelating resin filter element, the chelating resin filter element has a strong adsorption capacity, can absorb heavy metal ions in tap water, and the heavy metal removal module 20 adopts a disposable design, after the chelating resin absorbs heavy metal ions and is saturated, The heavy metal removal module 20 can be disassembled and replaced with a new chelating resin filter element to continue to use, the maintenance process is simple and convenient, and the cost of water purification can be effectively saved.

Further, in the water purifier 100 of this embodiment, its water inlet 101 is connected to the outlet 200 of tap water, and the water outlet 102 of the water purifier is connected to the valve 300, which can work under tap water pressure without additional installation of a booster pump , save energy consumption, and produce no noise. The entire water purification process of the water purifier 100 produces no waste water, saving water resources. Only three modules are used to achieve good water purification effects. The structure of the entire waterway is simple, reducing the risk of water leakage. Prompt the user experience.
