WATER STORAGE DEVICE, SANITARY WATER SUPPLY DEVICE, AND SANITARY CLEANING DEVICE

摘要

Disclosed are a water storage device, a sanitary water supply device, and a sanitary cleaning device. The water storage device is arranged in a cleaning waterway of the sanitary cleaning device and comprises a water tank (1) used for storing cleaning water, and the water tank (1) is provided with a water inflow structure and a water outflow structure. The water storage device further comprises: a buoyancy mechanism, which is arranged in the water tank (1) and comprises a first buoyancy component (2), and a control switch, which is arranged at the top of the water tank (1). The first buoyancy component (2) of the buoyancy mechanism, when same has floated to a first position, is linked with the control switch to output a signal for controlling the water tank (1) to stop water inflow, the first buoyancy component (2), when same has lowered to a second position, is linked with the control switch (3) to output a signal for controlling the water tank (1) to carry out water inflow, and the first position is higher than the second position. The buoyancy mechanism matches with the control switch (3) to detect an upper limit water level and a lower limit water level of the water tank (1), such that not only can the water inflow condition of the water tank (1) be effectively controlled, and the cost is low, but also, a power-on and water-off water-electricity separation mode is used, such that same is safe to use.
