The filter tank 24 is internally provided with a filter material which can be synthetic fiber filter cotton or other common filter materials. The height of the filter tank 24 is larger than that of the overflow port, so that the water level in the filter tank 24 is higher than that in the incubation tank 1, and the water in the filter tank 24 is pressed into the incubation tank 1 under the action of gravity. The water storage tank 23 is used for supplying water to the filter tank 24, and the water storage tank 23 is communicated with the filter tank 24 through a water supply system. The regulating system is used for regulating the water quality in the water storage tank 23 and comprises a sensor system 18, a controller 16, a heater 17 and an aeration device. A sensor system 18 is provided in the reservoir 23 to monitor the water quality in the reservoir 23. The controller 16 is electrically connected to the sensor system 18 and the aeration device, respectively, to control the amount of aeration of the aeration device into the reservoir 23 based on the water quality in the reservoir 23. The heater 17 is positioned in the water storage tank 23, the heater 17 is electrically connected with the controller 16, and the heating temperature and the heating time of the heater 17 can be adjusted through the controller 16, so that the temperature of the hatching water can be adjusted.
When the device is used, a certain amount of water is injected into the water storage tank 23, the water in the water storage tank 23 is introduced into the filter tank 24 through the water supply system, and enters the incubation tank 1 after being buffered and filtered by the filter tank 24, so that the water inlet mode of micro water flow is realized.
