Abstract

The utility model discloses a kind of descaling device and flush-free urinal, descaling device is used for bathroom sanitary ware, including the liquid storage container for storing descaling liquid, pumping module and liquid delivery pipe, pumping module includes pumping pump, the liquid inlet end of this pumping pump is communicated liquid storage container, the liquid outlet end of pumping pump is communicated one end of liquid delivery pipe, to be transported to the descaling liquid pumped by pumping pump to the sewage passage of bathroom sanitary ware by liquid delivery pipe.The descaling device of the utility model is applied to bathroom sanitary ware, especially when flush-free urinal, can effectively remove the urine scale accumulated in sewage passage, significantly improve the phenomenon that the flow of sewage passage is not smooth and sewage efficiency is reduced due to scale formation.Compared with the traditional mechanical dredging mode needing to disassemble accessory, the descaling device of the utility model realizes more convenient and efficient maintenance operation, avoids complex disassembly process, makes product maintenance become simple and easy.
