The utility model provides an alkaline zinc-manganese battery which comprises a battery steel shell, a cathode current collector assembly is assembled at the upper end of the battery steel shell, an anode ring is coaxially embedded in the battery steel shell, an isolation tube is sleeved in a central cavity of the anode ring, and cathode zinc paste is filled in the isolation tube; an annular closed cavity is defined by the top surface of the positive electrode ring, the bottom surface of the negative electrode current collector assembly, the outer circumferential surface of the isolation tube and the inner circumferential surface of the battery steel shell, a hydrogen storage piece is embedded in the closed cavity, and the hydrogen storage piece is formed by pressing a hydrogen storage material. According to the alkaline zinc-manganese battery disclosed by the utility model, hydrogen generated in the battery can be transferred and stored in the hydrogen storage material in time, so that air pressure change in the battery caused by hydrogen evolution in the battery and side effects caused by the air pressure change are prevented.

The utility model relates to an automatic filter device for water quality detection, include: the shell is inside and is established pressure chamber, the left and right sides of shell are fixedly connected with water inlet and drain respectively, and the position of pressure chamber is detachably connected with filter core near drain, pump liquid subassembly is set up in the side of shell near water inlet, is used for reciprocating pumping liquid. The utility model relates to the technical field of water quality detection. The automatic filter device for water quality detection can be used for filtering the impurity particle of interfering detection in sewage through the filter core set up, thereby improves the detection accuracy, and the anti -blocking subassembly set up in the shell can use the backflushing filter core of filtered water when reciprocating pumping water of pump liquid subassembly, can effectively prolong the service life of filter core, thereby reduces the use cost of automatic filter device, further improves the practicality of automatic filter device.
