Technical Field

The invention relates to the technical field of bath appliances, in particular to a novel shower water purification shower head capable of synchronously removing hardness, residual chlorine and pathogenic microorganisms in water.

Background

In recent years, researchers have conducted studies on water quality improvement methods for the water quality characteristics of bathing water. Aiming at the problem of hardness in water for bathing, the conventional water purification shower head generally adopts a filter material filtering method (interception effect) comprising an interception filter screen, a PET (polyethylene terephthalate) non-woven fabric, activated carbon fibers and the like, but the interception filter screen and the PET non-woven fabric can only remove suspended particles with larger particle size, and the filtering effect is poor; although the activated carbon fiber can remove the hardness of the formed calcium carbonate and magnesium carbonate precipitates, the activated carbon fiber cannot remove the hardness of calcium/magnesium which is soluble in water and cannot realize the softening of water; therefore, there is a need to find a method for simultaneously removing the hardness of the calcium carbonate and magnesium carbonate precipitates and the soluble calcium/magnesium hardness.

Aiming at the problem of residual chlorine in bath water, the prior art mainly removes the residual chlorine in the bath water by a method (oxidation-reduction reaction) of adding reducing substances, wherein the commonly used reducing substances comprise sulfur dioxide, sodium sulfite, sodium bisulfite, sodium thiosulfate, activated carbon, KDF (high-purity copper/zinc alloy), activated carbon and the like. Sulfur dioxide, sodium sulfite, sodium bisulfite and sodium thiosulfate can be removed by oxidation-reduction reaction with residual chlorine, but a large amount of sulfate radicals (SO) are generated by oxidation reaction of residual chlorine with sulfur dioxide, sodium sulfite, sodium bisulfite, sodium thiosulfate and the like₄ ^2-) May not satisfy the highest allowable SO in drinking water₄ ^2-And (4) specifying the concentration. KDF filter material, which can be oxidized-reduced (electrically) by electrochemistryDaughter transfer) reaction effectively reduces or removes chlorine in water, but residual chlorine chemically reacts with KDF to release copper ions (Cu)²⁺) And zinc ion (Zn)²⁺) There is a possibility that the maximum allowable copper and zinc contents in drinking water cannot be satisfied. The activated carbon filter material is a porous material, has the functions of adsorption, interception and reduction, can effectively intercept suspended substances in water, adsorbs organic pollutants and heavy metals in the water, and removes residual chlorine through oxidation-reduction reaction. However, the activated carbon material is a porous material and has a large number of pore structures, so that a large number of organic pollutants can be adsorbed, favorable conditions, namely rich carbon sources, are provided for breeding of microorganisms, the breeding of the microorganisms on the activated carbon material can generate the risk of microorganism leakage, and particularly, the shower water has potential safety hazards due to the leakage of pathogenic microorganisms. Therefore, it is also necessary to ensure that residual chlorine in the shower water is removed and that the water does not contain substances (Cu) with potential safety hazards²⁺、Zn²⁺、SO₄ ^2-And microorganisms, etc.).

Aiming at the problem of pathogenic microorganisms in water for bathing, according to the national standard requirements, the regeneration of the microorganisms is controlled by using residual chlorine in water in the prior art, warm water is reserved in a hose part connected with a spray head in a shower device for a long time, the release of carbon-containing substances in the hose can be accelerated by the residual chlorine in a warm water environment, the carbon-containing substances become nutrient substances of bacteria and pathogenic bacteria, the bacteria in the hose can be propagated again when the residual chlorine is consumed, the bacteria in the hose can flow out along with the next shower, directly contact with people, or float in the air along with steam, enter the human body along with respiration, and the pathogenic risk of bacterial infection exists. Therefore, it is necessary to remove microorganisms trapped in the shower water.

However, the existing water purification shower head or water purification device for shower only controls the residual chlorine and suspended substances in water, and does not consider the risk of microorganism regeneration in the water for shower and the damage of calcium and magnesium hardness to skin, for example, the main filter element of the Philips (Philips) household chlorine removal shower head adopts a KDF filter material, which can effectively reduce or remove the chlorine and heavy metals in water through electrochemical oxidation-reduction (electron transfer) reaction,but the chemical reaction of residual chlorine and KDF releases copper ions (Cu)²⁺) And zinc ion (Zn)²⁺) There is a possibility that the maximum allowable copper and zinc contents in drinking water cannot be satisfied. The TOCLAS water purification shower head imported from Japan adopts a triple purification mode of PET non-woven fabric-activated carbon fiber-calcium sulfite, but calcium sulfite is oxidized by residual chlorine to generate a large amount of sulfate radicals (SO)₄ ^2-) May not satisfy the highest allowable SO in drinking water₄ ^2-And (4) specifying the concentration. In addition, the activated carbon material has the functions of adsorption, interception and reduction, can effectively intercept suspended substances in water, adsorbs organic pollutants and heavy metals in water, and removes residual chlorine through oxidation-reduction reaction. However, the granular activated carbon has a rough surface, and a large amount of organic matters are adsorbed on the surface, so that favorable conditions are provided for breeding of microorganisms, and the phenomenon of breeding of microorganisms in the activated carbon filter material is easily caused. Therefore, the single use of activated carbon as the filter material of a shower water purification sprinkler without a subsequent disinfection step is a safety risk. In summary, the current research and the development of commercial water purification shower products are mostly aimed at removing suspended substances, residual chlorine and heavy metals in the bath water, and controlling the hardness of residual chlorine, calcium and magnesium (Ca) in the bath water²⁺、Mg^{2 +}) And pathogenic microorganisms, and the like, and lacks a shower water purification shower head device capable of synchronously removing hardness, residual chlorine and pathogenic microorganisms in water.
