    • A faucet assembly comprise: a water supply pipeline comprising a water outlet pipeline section (1100) and a water inlet pipeline section (1200) connected to each other, wherein the water inlet pipeline section (1200) contains a throat section (1201) with smaller cross sectional diameter; a shell (1300) made of hard materials and wrapped around the throat section (1201), so as to define a space (1202) that contains air around the throat section (1201), while the throat section (1201) has an opening to the space (1202); a flexible membrane wrapping layer (1400) made of elastic materials and is hermetically sealed on the inner side of the shell (1300), so that the space that contains air has an elastic, retractable and sealed boundary, and not equipped with a heater; a heater (1500), which is connected in series to the aforesaid inlet pipeline section (1200) and is positioned in the upstream of the aforesaid shell (1300) along the water outlet direction, to heat the water that is about to flow into the throat section (1201). The faucet assembly can take advantage of the negative pressure to return water when the water supply is stopped; it has a larger deformable closed space, wherein a larger negative pressure can be formed. No retained water in the outlet conduit can be realized when turning off the faucet, at the same time, no leakage in the water outlet can be achieved when heating the water. It can realize the output of four kinds of water, no retained water in the outlet conduit and at the same time no leakage occurring in the water outlet when heating the water.
    • 一种龙头组件,包括:供水管路,包括相互连接的出水管路段(1100)和进水管路段(1200),其中,进水管路段(1200)包含喉部(1201) 横截面直径; 由硬质材料制成并围绕喉部1201以限定包含喉部1201周围的空气的空间1202的壳体1300,同时喉部1201具有至 空间(1202); 由弹性材料制成的柔性膜包裹层(1400),其被密封在壳体(1300)的内侧上,使得包含空气的空间具有弹性的,可伸缩的和密封的边界,并且不配备加热器; 与上述入口管路部分(1200)串联连接并且沿着出水方向位于上述壳体(1300)的上游的加热器(1500),用于加热即将流入 喉部(1201)。 当停止供水时,龙头组件可以利用负压来返回水; 它具有较大的可变形封闭空间,其中可形成较大的负压。 关闭水龙头时,出水管内不会有残留的水分,同时加热水时不会出现渗水。 它可以实现四种水的输出,出水管道内不留积水,同时加热水时不出水。
