Description

Water purification quality guaranteeing system

Technical Field

The invention particularly relates to a water purification quality guarantee system.

Background

The existing water purification system comprises a raw water supply unit, a raw water purification unit, a water-air mixer, a booster pump, a water purification tank, a hot liner, a water faucet assembly, an ozone generator and an air pump, wherein the water faucet assembly comprises a cold water faucet and a hot water faucet, the water purification tank comprises a water tank body and a water tank cover used for sealing the water tank body, the water tank body is connected with a water inlet connector and a water outlet connector, the water tank body is also provided with a steam inlet, the water outlet connector is communicated with a water inlet of the hot liner and the cold water faucet, the steam inlet is communicated with a steam outlet of the hot liner, and the water inlet connector is communicated with a water outlet of the booster pump. The raw water supply unit is communicated with the water inlet end of the water-gas mixer through the raw water purification unit, the air pump is communicated with the air inlet end of the ozone generator, the output end of the ozone generator is communicated with the air inlet end of the water-gas mixer, the water outlet end of the water-gas mixer is communicated with the water inlet of the booster pump, and the water outlet of the hot liner is communicated with the hot water faucet.

The raw water supply unit provides raw water which does not accord with the drinking water standard, and the raw water is purified by the raw water purification unit, mixed with ozone by the water-gas mixer and then output ozone water to the water purification tank. On one hand, water stored in the water purifying tank enters the hot liner to be heated, and hot water is supplied through the hot water faucet. The water stored in the clean water tank is supplied with normal temperature water through a cold water faucet.

Existing water purification systems have the following disadvantages:

firstly, after ozone water is delivered to a water purification tank, ozone in the water is naturally decomposed into oxygen-enriched water which is rich in oxygen and is suitable for drinking, but if water is taken little or water is not taken for a long time, water in the water purification tank and a pipeline is aged or polluted, so that the water is not suitable for drinking and is harmful to human health.

Secondly, because the water quality is easy to age and pollute, bacteria and pollutants are easy to accumulate in the water purifying tank and the pipeline, the water purifying tank and the pipeline need to be cleaned regularly, the use and maintenance cost is increased, and meanwhile, cleaning agent residues are generated, and the human health is harmed.

Thirdly, in the process of taking water, because the ozone water is continuously supplemented into the water tank body, the newly added ozone water is continuously mixed into the oxygen-enriched water in the original water tank body, and the water taken by the user contains certain ozone, has special fishy smell and affects the use.

Fourthly, when the hot courage heats, steam in the hot courage gets into this internally through steam inlet water tank, heats this internal water of water tank to a certain extent, and cold water tap receives the water through steam heating through water connectors, influences cold water taste.

Fifthly, the water faucet assembly comprises a water outlet nozzle, wherein the water outlet nozzle is cylindrical, one half of the water outlet of the cold water faucet and one half of the water outlet of the hot water faucet are both communicated with the outside through the water outlet nozzle, and finally, the cold water and the hot water both flow out through the water outlet nozzle. Because the pipe diameter of the water outlet nozzle is large, the water outlets actually used by the cold water faucet and the hot water faucet are only half of the area of the water outlets, so that the water flow from the cold water faucet and the hot water faucet is small, the flow speed is slow, the water pressure is low, the effect of flushing the inner wall of the water outlet nozzle cannot be achieved, bacteria on the inner wall of the water outlet nozzle cannot be flushed, and the drinking water pollution is caused. Meanwhile, the water outlet nozzle is integrally connected with the faucet component, so that the faucet component is inconvenient to clean.

Sixthly, the water-gas mixer is easy to be corroded by ozone and return water, so that the ozone generator does not generate ozone when meeting water and corrode the ozone generator, the function of sterilizing and disinfecting water by using ozone is lost, the working reliability is low, the human health is harmed, the use and maintenance cost is increased, and the working reliability is low.

In a word, in the existing water purification system, purified water cannot be circulated, is easy to be secondarily polluted, cannot supplement oxygen according to needs, and is low in quality.
