Fluid state detection device and salt chlorine machine

The embodiment of the utility model relates to the technical field of fluid detection, in particular to a fluid state detection device which is used for detecting the flowing state of fluid and comprises an electrolysis unit, a sensing unit and a shell. The electrolysis unit and the sensing unit are at least partially arranged in the shell; the electrolysis unit is configured to be capable of electrolyzing fluid in the shell so as to change the chemical characteristics of the fluid; the sensing unit is configured to be capable of detecting the chemical characteristics of the fluid in different flowing states in the shell so as to detect the flowing states of the fluid, the chemical characteristics, changed by the electrolysis unit, of the water body can be detected through the sensing unit, and in some cases, the component content change in the flowing water body is small; the component content change in the static water body is large, so that the function of determining the flowing state of the fluid without
