Abstract (en)
A sanitary cleaning device (1) including a nozzle (40), a water supply path (50), a backflow prevention mechanism (90), and a solution provision unit (100). The backflow prevention mechanism includes a tank (91) provided on the water supply path, a water inlet port (92) that is communicated with an upstream water supply path (51) on the water supply path and through which water flows into the tank, a water outlet port (93) that is communicated with a downstream water supply path (52) on the water supply path and through which water in the tank flows out to the downstream water supply path, and an overflow port (94) provided to form an air gap between the overflow port and the water inlet port. The solution provision unit includes a provision port (121) through which acid solution is provided by the user, a solution supply path (113) through which the acid solution provided through the provision port circulates, and a solution inlet port (112) through which the acid solution flowing through the solution supply path flows into the tank. The solution supply path of the solution provision unit includes an expansion part in which a flow-path cross-sectional area increases toward the solution inlet port (112).
