A water circulation unit for a fish bowl is provided to achieve excellent circulation and purification efficiencies by circulating water which flows into an inflow tower uniformly from an upper and a lower inflow hole thereof. A water circulation unit for a fish bowl includes: an inflow tower(10); a circulation pump(20), arranged in an upper part inside the inflow tower; a filter(40), arranged directly under the circulation pump; an upper inflow hole(11), formed in an upper periphery of the inflow tower; a lower inflow hole(12), formed in a lower periphery of the inflow tower; a discharging hole(13), arranged in one upper side of the inflow tower so as to be connected to a discharging pipe; an inflow space(14), arranged in front and rear centers inside the inflow tower respectively so as to be connected to the corresponding inflow hole; and a pumping space(15), arranged in a lower end inside the inflow tower so that water is fed from the inflow holes and the inflow space through the pumping space to the circulation pump, and then discharged to the discharging pipe. |
