Abstract
The invention relates to a water quality detection electrode capable of automatically exchanging a membrane. The water quality detection electrode comprises a water quality detection electrode body, wherein the lower end of the water quality detection electrode body is sleeved by a sleeve shell; the sleeve shell is internally provided with two fully-closed cavities which are mutually separated; the left cavity located at the left side is internally provided with a roller which is wound by a filtering layer; an outlet end of the filtering layer on the roller transversely penetrates through a water inlet at the middle part of the sleeve shell and penetrates into the right cavity at the right side of the sleeve shell to be fixedly connected with a rotary shaft; the width of the filtering layer is greater than the diameter of the water inlet. According to the water quality detection electrode capable of automatically exchanging the membrane, a filtering layer structure capable of being automatically replaced is additionally arranged at the water inlet end and is used for separating dirt in water, so that the dirt is prevented from being contacted with sensitive parts on the water quality detection electrode; the water quality detection electrode has a good filtering effect and is convenient to use.
