Description
Technical Field
The utility model relates to a water faucet, in particular to a water faucet with a water purifying function.
Background
Water is the source of life and the basis of health, water is the basis on which human beings and animals and plants live, and safe drinking water is vital to human health. With the development of society, the increase of population and the improvement of industry, water pollution is inevitably a real problem facing people, so that various household water purifiers become indispensable household appliances in daily life of people. However, the water purifiers on the market have poor product quality due to the difference of the advanced manufacturing process and are expensive. Especially, the water filtered by the reverse osmosis membrane is too pure and does not contain any pollutant, but also lacks the mineral substances and trace elements in the water; and electricity is consumed to boost the pressure to produce water, and at least two cups of wastewater are wasted when one cup of pure water is produced; most importantly, drinking too pure water for a long time is not good for health, and the water purifier is expensive and needs frequent replacement of the filter element.
The healthy drinking water actually restores the essence of natural water, removes rust, silt, pathogenic microorganisms, namely two worms (recessive sporozoon and giardia), bacteria, viruses living by parasitic bacteria and the like caused by secondary pollution in the water, and retains original mineral substances and trace elements in the water, so that the water is really healthy. The aperture of the ultrafiltration membrane is generally concentrated between 0.01 and 0.1 micron, which can just intercept various harmful substances in the tap water and retain beneficial mineral substances and trace elements in the water. However, ultrafiltration membranes with high market share are mainly organic polymer membranes, and most of the organic polymer membranes used in water purifiers are hollow fiber-shaped, and the shortage of low flow rate is compensated by high packing density. However, the filter element is prepared by adopting a phase inversion process, the influence factors in the phase inversion process are more, the formed aperture is uncontrollable, the aperture distribution is wider, the concentration ratio is poor, and the biological safety cannot be 100 percent guaranteed; secondly, the film made of the organic polymer material is soaked in water all day long, is easy to age and break silk, and even can overflow toxic substances. Finally, the organic polymer membrane has strong hydrophobicity, is easy to adhere bacteria, and has membrane aperture blockage, so the service life of the filter element is generally 6-24 months.
Besides the organic polymer filter element, a ceramic filter element is also provided, which is formed by firing diatomite at a high temperature. Because the diatomite is a porous material without regular particle shapes, the prepared ceramic filter element cannot be called a membrane filtration product, a fine screening mechanism basically does not exist, and the water purification mechanism with narrow pore size distribution and high filtration precision can be understood as a small part of coarse screening interception and a large part of capillary pore adsorption. Therefore, the safety of the produced water quality can be thought by adopting the filter element for purifying water, and the safety guarantee function is not realized. The diatomite filter element is mainly used for purifying water by adsorbing pollutants in water through developed capillary pores of diatomite, the filter element needs to be manually disassembled after the diatomite filter element is used for a week or a half month, the layer of diatomite with saturated adsorption is scrubbed by scouring pad or sand paper, and then the diatomite filter element is continuously adsorbed for use. If the membrane separation layer is fine, the original filtering precision can be damaged by sanding; and the thinner the general membrane separation layer is, the smaller the resistance to water permeation is, and the better the separation performance of the membrane is.
The filter element which can be really called as a ceramic membrane mainly comprises two types: alumina and silicon carbide. The alumina ceramic membrane support, the transition layer and the membrane layer are made of smaller powder, so that the prepared membrane has low porosity and large water permeation resistance. The water purifier with the alumina ceramic membrane filter element cannot be found in the whole water purification market, and the main reason is that the particle of the alumina support body is too small, the water production flux is too low, and the standard 2L/min of the water outlet of the water dispenser cannot be reached at all, which is the root cause that the water purifier with the real alumina ceramic membrane filter element as the filter element cannot be found in the market, the water production flow is too small, and the user experience is too poor. Silicon carbide is used as a novel ceramic membrane material, has the characteristics of large water permeation flux and good pollution resistance under the same aperture compared with an alumina ceramic membrane, and can be widely used in the water purification process of drinking water.
The tap is an indispensable daily product in family life, and is mainly used for controlling the water volume of running water and opening and closing. However, the conventional water faucet only has the functions of controlling the speed of tap water and opening and closing, and the functions are single. The utility model provides a water faucet with a water purifying function, which adopts a silicon carbide ceramic membrane as a filter element, based on the requirements of the current household water purifier that the cost is high, the product quality is not uniform, the safety is not guaranteed and people want to really obtain healthy drinking water.
