The invention discloses a multilayer detachable three-dimensional freshwater fish temporary rearing bin which comprises a bin body and a plurality of detachable temporary rearing bins located in the bin body, the temporary rearing bins are slidably arranged in containing grooves formed in the bin body, and the temporary rearing bins located on the same column are vertically aligned at equal intervals to serve as an experimental group. And a communicating assembly movably penetrating through each temporary rearing bin is arranged in each experimental group correspondingly. According to the freshwater fish temporary rearing device, distinguishing, temporary rearing, observation and experimental operation of freshwater fish can be achieved, circulation can be achieved, the communicating assembly is matched, fishes are prevented from entering other temporary rearing bins at the communicating position, connectivity of all the temporary rearing bins is assisted to be slowed down, great help is provided for observation of experimental operation such as virus resistance, infectivity and virus tolerance of the freshwater fish, and the survival rate of the freshwater fish is increased. The method has scientific research value and daily use value.

The present invention relates to a user-detecting water-saving flush valve. Toilets installed in public restrooms or office buildings are equipped with flush valves, and after a user finishes using the toilet, they operate a lever to flush the toilet by discharging water from the inlet pipe through the outlet pipe. However, due to infectious viruses such as COVID-19, users are reluctant to operate the lever, and sometimes, users fail to operate the lever while distracted, causing serious discomfort to the next user. Therefore, the present invention relates to a semi-automatic water-saving flush valve that detects the user's movement and allows the toilet to be flushed automatically after use without the user having to operate the lever for defecation or urination.
