As a preferred embodiment of the present utility model, as described in accompanying drawing 1, tap water enters from tap water inlet 1, passes through three-way ball valve 2 sequentially along water inlet pipe 9, pressure reducing valve 3, polypropylene melt-blown filter element 4 , granular activated carbon filter element 5, carbon rod filter element 6, water inlet solenoid valve 7, magnetized water quality processor 8, pressure stabilizing pump 10, reverse osmosis membrane filter device 11, check valve 13 on the outlet pipe 12, high pressure switch 14, storage Water pressure tank 15, post-installed granular activated carbon filter element 16, water outlet 17; reverse osmosis membrane filter device 11 is also connected with waste water port 21 through waste water pipe 22 at the same time, and waste water pipe 22 is provided with combined solenoid valve 18 with waste water ratio in sequence, Rear activated carbon fiber filter element 19, rear diatomaceous earth ceramic filter element 20, waste water outlet 21.

Described three-way ball valve 2, three-way ball valve has T type and L type. The T-shape can make the three orthogonal pipelines communicate with each other and cut off the third channel to play the role of diversion and confluence. The L three-way ball valve type can only connect two pipelines that are orthogonal to each other, and cannot maintain the interconnection of the third pipeline at the same time, and only plays a distribution role. The utility model selects whether to feed tap water through the opening and closing of the three-way ball valve.

The pressure reducing valve 3 is used to detect the low water pressure in the water pipe, and avoid the idling operation of the pump when the water pressure is low.

The polypropylene melt-blown filter element 4, the granular activated carbon filter element 5, and the carbon rod filter element 6 belong to the pre-filter element processing group, and the function of the pre-filter element processing group is to perform preliminary filtration on tap water. Among them, the polypropylene melt-blown filter element 4 is made of continuous polypropylene long fibers produced by the melt-blown process, has chemical compatibility, and is used for main filtration to remove mud, sand, rust, and suspended solids in water; the granular activated carbon filter element 5 is made of non-toxic Toxic and tasteless high-efficiency coconut shell activated carbon and coal-based activated carbon are used as the main body, supplemented by food-grade material binders, which are often prepared by expensive processes. They are mainly used for adsorption and removal of heavy metals, pesticides, colloids, and organic substances (chloroform, Carbon tetrachloride, haloacetic acid, phenols, endocrine disruptors, antibiotics, etc.), residual chlorine, chroma, turbidity, odor and taste, etc.; the carbon rod filter element 6 is made of high-quality activated carbon, and is bonded with low thermal melting The agent is obtained by continuous extrusion molding, which can simultaneously play the role of filtration and adsorption, so it can remove heavy metals, pesticides, suspended solids, colloids, organic matter, residual chlorine, color, turbidity, odor and taste in water. The pre-filter element treatment group is formed by connecting the above-mentioned different filter elements in series, and performs multiple filtrations on the tap water to remove most impurities and peculiar smells in the water, and can reduce the filtration burden of the reverse osmosis filter device 11 behind.

Described water inlet solenoid valve 7 is in normally closed state in the fact that does not make water, just opens when making water.

The unique magnetized water quality processor 8 of the utility model can be a permanent magnet type processor, comprising at least one pair of magnets and a shell covering the magnets, and each pair of magnets is respectively arranged on both sides of the water inlet pipe.

The unique magnetized water quality processor 8 of the utility model can also be an eddy current type magnetized water treatment device, comprising a shell provided with a water inlet and a water outlet, the shell is a hollow cylinder structure, and the interior is provided with a cylindrical magnetic energy generating device. There is a gap between the magnetic energy generating device and the outer surface to form an annular water tank. Due to the water pressure, when the water flows through the annular water tank, a spiral vortex is formed along the outer surface of the magnetic energy generating device, and then flows out from the water outlet. The magnetic energy generating device can generate a magnetic field. The pressure action causes the water flow to generate a spiral eddy current along the magnetic field lines, which increases the path for the water to be magnetized in the magnetic field of the magnetic energy generating device, so that the water molecules can absorb a large amount of magnetic energy. The magnetized water quality processor 8 can change the physical and chemical properties of water, reduce the fouling of the reverse osmosis filter device, and effectively prolong its service life.

The pressure stabilizing pump 10 mainly increases the stable pressure for the reverse osmosis membrane filter device 11 to realize the effect of reverse osmosis.

Reverse osmosis membrane filtration device 11, that is, RO reverse osmosis membrane, because the pore size of the RO membrane is five millionths of a hair, it is generally invisible to the naked eye, and bacteria and viruses are 5,000 times larger than it. Therefore, only water molecules and some Mineral ions beneficial to the human body can pass through, and other impurities and heavy metals are all discharged from the waste water pipe 22 .

The reverse osmosis membrane filter device 11 is connected to the water inlet of the high pressure switch 14 through the check valve 13 on the water outlet pipe 12. The check valve 13 can prevent the backflow of water in the water outlet pipe 12, which affects the water purification of the reverse osmosis membrane filter device. .

The water storage pressure tank is used to store clean water.

The post-installed granular activated carbon filter element 16 can recontaminate the purified water in the water storage pressure tank 15 to ensure the purity of the effluent.

The reverse osmosis membrane filtration device 11 is connected to the waste water pipe 22, and the combined solenoid valve 18 with waste water ratio can better control the opening and closing of the waste water pipe 22, so as to realize the automatic discharge of water in the waste water pipe.

Further than the prior art, the preferred embodiment of the utility model is provided with a post-installed activated carbon fiber filter element 19 and a post-installed diatomite ceramic filter element 20 on the waste water pipe 22, and they can further filter and adsorb the waste water, so that The waste water coming out of the waste pipe can still play a role in the process of laboratory use.

Preferably, the raw material of the activated carbon fiber filter element is viscose-based fiber or polyacrylonitrile fiber, and the fiber diameter is 5-10 microns. The porosity of the diatomite ceramic filter element is 0.05-0.2 microns.

Specifically, when the water purification device shown in accompanying drawing 1 is energized to produce water, when the high pressure switch 14 detects a high pressure, the high pressure switch takes off, and the waste water ratio combination solenoid valve 18 is closed, and passes through the pre-filter element treatment group, the magnetized water treatment device 8 The pure water treated with the reverse osmosis membrane filtration device 11 enters the water storage pressure tank 15 . When the pressure water storage tank 15 is full of a bucket of water, the high pressure switch 14 cannot detect the high pressure signal, and the high pressure switch 14 is closed. When pure water needs to be used, the water outlet 17 is opened, and the water in the pressure water storage tank 15 comes out from the water outlet 17 through the outlet pipe 12 through the rear filter element 16, and can be used directly, which is safe and reliable. When the water requirement used in the experiment is slightly lower than that of pure water, the waste water outlet 21 can be opened to use the filtered waste water through the rear filter elements 19 and 20.

The utility model adopts a multi-stage filter core structure before and after the reverse osmosis membrane filter device, which effectively improves the utilization rate of raw water and reduces the waste of water resources; moreover, a magnetized water treatment device is also set in front of the reverse osmosis membrane filter device , reducing the fouling phenomenon of the reverse osmosis membrane filter device, effectively improving its service life.

It should be understood that this description is not intended to limit the present invention to the above-mentioned exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments within the spirit and scope of the invention as defined by the appended claims.
