[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0013] The following describes an embodiment of the utility model based on its overall structure.

[0014] like Figure 1 The specific embodiment of the automatic backwashing pH detector shown includes a pH meter sensor base 13; the pH meter sensor base 13 is provided with a threaded hole to install a pH sensor 9, and the threaded part is sealed; the pH sensor base 13 is installed with a drain pipe 7, a clean water pipe 9 and a sewage pipe 10 through a clamp joint, and the installation part is sealed; one end of the sewage pipe 10 is connected to the pH sensor base 13, and the other end is installed in the sewage pipe 11 with a filter screen 12; a sewage outlet 14 is provided at the bottom of the pH sensor base 13.

[0015] Specifically, a filter 12 is provided to prevent debris from damaging the probe portion of the pH sensor 9 and affecting the measurement result.

[0016] Specifically, one end of the clean water pipe 8 is connected to the PH sensor base 13, and the other end is connected to the clean water source; the clean water switch valve 1, the clean water switch valve 2, the clean water check valve 1, and the clean water check valve 2 are installed on the clean water pipe 8 in sequence.

[0017] Specifically, the drainage pipe 7 is sequentially installed with a drainage switch valve 3 and a flow regulating valve 4 .
