Water purification faucet
A faucet body is provided with a purified water flow channel, a waste water inlet pipe, a waste water outlet pipe, a transition hole and a vent hole, the purified water flow channel is connected with a purified water outlet of a filter, the waste water inlet pipe is connected with a waste water outlet of the filter, the transition hole is communicated with the waste water inlet pipe and the waste water outlet pipe, and the vent hole is communicated with the waste water outlet pipe and external air; the diameter of the transition hole is smaller than the pipe diameter of the wastewater outlet pipe and smaller than that of the vent hole, when wastewater in the wastewater outlet pipe is about to flow back, air in the vent hole enters the wastewater outlet pipe to form an air gap, and the vacuum state in the transition hole can be cut off to prevent wastewater from flowing back. Therefore, by arranging the simple structures in the faucet body, reverse flow of waste water can be permanently achieved, not only is excessive space in the faucet body not occupied, but also the structure of the filter can be greatly simplified, the size of the filter can be reduced, and more space under the table can be released.
本发明公开了净水龙头，龙头本体设有净水流道、废水进水管、废水出水管、过渡孔和通气孔，净水流道与过滤器净水出口相连，废水进水管与过滤器废水出口相连，过渡孔连通废水进水管和废水出水管，通气孔与废水出水管、外界空气相连通；过渡孔孔径小于废水出水管管径，且过渡孔孔径小于通气孔孔径，废水出水管内的废水即将出现逆流时，通气孔内的空气进入废水出水管内以形成空气间隙，可切断过渡孔内的真空状态，以避免废水逆流。由此，通过在龙头本体内设置该些简单的结构便能永久实现废水的反逆流，不仅不占用过多的龙头本体内的空间，而且还可极大简化过滤器的结构以及减小过滤器尺寸，进而释放更多台下空间。
