A birdbath fountain includes a water reservoir and recirculating system. Water for the fountain is pumped from the reservoir, with the excess water from the bowl being returned to the reservoir, thereby allowing for a bowl which remains full or at a consistent depth for a longer period of time, including periods of dry or windy weather conditions. In the preferred configuration, the bowl has a depth defined by an outer raised rim and an inner raised rim. A water-containing reservoir having a depth greater than the depth of the bowl resides within the inner raised rim. An electrically operated submersible pump disposed in the water-containing reservoir is operative to pump water from the reservoir to the fountain head, after which the water returns to the bowl. At least one notch in the inner raised rim provides a fluid path from the bowl back to the reservoir, thereby keeping the water level of the bowl substantially constant.

The top of the pipe extends into the cavity of the water supply device, and the water inlet pipe is connected between the sluice and the water supply device; the flow of water in unsaturated soil is generalized as a one-dimensional flow of water in vertically arranged open-hole containers under the action of gravity Flow model, using the principle of water balance and Bernoulli equation, for hydraulic calculation and derivation, the relationship between flow velocity and water level of any container unit at any time is obtained, and the model is verified by experiments. The results are in line with theoretical assumptions and unsaturated Soil seepage law.

The present invention relates to a bio-ink supply system, and more particularly, to a bio-ink supply system comprising: a hydrogel storage part; a cell storage unit; a mixing unit for receiving the hydrogel and the cell solution from the hydrogel storage unit and the cell storage unit; a sensor part for measuring the water level of the bio-ink inside the syringe; and a control section that receives a signal from the sensor section to maintain a constant water level of the bio-ink inside the syringe, and the mixing section supplies the bio-ink prepared by mixing a hydrogel and a cell solution to the syringe. The bio-ink supply system according to the present invention can continuously supply active bio-ink to a syringe of a bio-printer even in a 3D bio-printing process, and thus can continuously print large-scale living body tissues, or a plurality of orgonoids, organ chips, and the like.
