Description

水龙头的改良结构 技术领域 本发明涉及水龙头的技术领域， 与其改良结构有关。 背景技术 随着科技的发展，人们对生活环境的卫生要求也越来越高。比如： 在一些提供直饮水的地区和国家，已经采用不锈钢材质的水管输送水 源。 但是， 目前水龙头的本体大多仍是利用生铁或铜铸造成型， 这种 水龙头， 不仅本身与水接触后会生锈或产生铜绿， 生成有毒物质， 使 水质发生变化， 而且， 水龙头与不锈钢水管因材质不同， 会产生电位 差， 更加速有毒物质的生成和生锈。  IMPROVED STRUCTURE OF A TURBINE FIELD OF THE INVENTION The present invention relates to the technical field of faucets and relates to improved structures thereof. BACKGROUND OF THE INVENTION With the development of science and technology, people's health requirements for living environments are also increasing. For example: In some regions and countries that offer direct drinking water, stainless steel pipes have been used to transport water. However, most of the faucet bodies are still cast by cast iron or copper. This faucet not only rusts or produces patina after contact with water, but also produces toxic substances, which change the water quality. Moreover, the faucet and stainless steel water pipe are made of materials. Different, it will produce a potential difference, which will accelerate the formation and rust of toxic substances.
因此， 本发明人针对现有水龙头的这一缺陷， 专门研制了一种不 锈钢本体的水龙头， 见中国发明专利 03239676. 7 《改进的水龙头》， 其直接利用不锈钢材质精密铸造一体成型水龙头本体，使水龙头的材 质与水管的材质相同而无电位差， 因而不会生锈或生成有毒物质， 以 保证用水卫生。  Therefore, the present inventors have specially developed a stainless steel body faucet for this defect of the existing faucet, see Chinese invention patent 03239676. 7 "Improved faucet", which directly uses a stainless steel material precision casting integrated molding faucet body, so that The material of the faucet is the same as that of the water pipe without potential difference, so it will not rust or generate toxic substances to ensure water sanitation.
但是， 对于类似图 1所示的不锈钢水龙头本体 10而言， 因为其 具有阀门 20的栓体 30安装在栓孔 40中后是支撑在阀座 50上，而阀 座 50处于本体 10的深处， 所以， 加工中存在不易在阀座 50上钻孔 成型的缺陷，加工难度高，废品率高，致使这类水龙头至今未能问世。  However, for the stainless steel faucet body 10 similar to that shown in Fig. 1, since the plug body 30 having the valve 20 is mounted in the bolt hole 40, it is supported on the valve seat 50, and the valve seat 50 is at the depth of the body 10. Therefore, there are defects in the processing that are not easy to be drilled on the valve seat 50, the processing is difficult, and the rejection rate is high, so that such faucets have not been available yet.
后有业者尝试将本体 10分成两段成型， 如图 2所示， 以方便在 阀座 50上钻孔， 但是， 本体 10的两段需通过焊接固定在一起， 焊接 精密度低， 焊接后的本体 10 内壁存在焊缝 A， 致使产品品质差， 所 以， 仍无法使不锈钢水龙头产品得到推广应用。  Later, the manufacturer tried to divide the body 10 into two sections, as shown in Fig. 2, to facilitate drilling on the valve seat 50. However, the two sections of the body 10 need to be fixed together by welding, and the welding precision is low, after welding. There is a weld bead A on the inner wall of the body 10, which results in poor quality of the product. Therefore, the stainless steel faucet product cannot be promoted and applied.
有鉴于此， 本发明人再度进行研究，对不锈钢水龙头的结构加以 改进， 本案油然而生。 发明内容 本发明的目的在于提供一种水龙头的改良结构， 使其加工容易， 成品率提高， 成本降低， 有利于产品的推广应用。  In view of this, the inventors conducted further research to improve the structure of the stainless steel faucet, and the case was born.
