Structural Features



The tabletop adopts a basic oval design, with square-round anti-collision structures added at the corners to effectively avoid bumps and collisions. The four sides are all heightened for leak-proof treatment, which can greatly reduce water splashing during use. The tabletop integrates a hand sanitizer pump and a detachable elbow water nozzle design, and a foldable funnel is provided as a gift.

If you encounter any problems during installation, you can contact customer service for consultation at any time.


The support column adopts a single-column design, innovatively equipped with a double-head installation structure: the top adopts a special-shaped buckle design; first press the large head firmly to fix it, then press along the direction of the small head to complete the stable installation. The bottom adopts a screw installation method; turn clockwise to the fixed buckle to ensure stable installation. The double-head installation design not only ensures the convenience of assembly and disassembly, but also fully guarantees the portability of the product. The support column is made by hollow blow molding process, with inherent structural rigidity, which is stable, durable and not easy to break. The column body is specially designed with a perforable pipe hole, inspired by the traditional Chinese bridge hole shape, which has both aesthetic and practical value.


Water Tank.With a capacity of 17L, the water tank adopts a foot-operated water outlet design, which is convenient and hygienic to use.
