Abstract: A desktop aquarium device with enhanced water filtration is provided. The aquarium device contains a base and a spherical tank. A filtering dish is installed inside the base. The filtering device provides a winding pathway for water to flow through. Along the pathway, biological filtering balls are placed. An air pump is also fixedly installed inside the base. The base is closed from the bottom by a bottom cover. The tank is locked to the base and the tank provides an aquatic environment. Inside the tank, there are a filtering device and a water outlet. Through the water filtration provided by the biological filtering balls along the water pathway inside the filtering dish, the water in the tank requires less frequent replacement, making the aquatic cultivation simpler and more convenient.

Abstract: A heating and pumping device for liquids, in particular for water of aquariums, the device comprising a pump (24) having a pump body (32) and a thermo-heating element (26) having a thermo-heating body (60). There is a casing (22) which contains both the pump (24) and the thermo-heating element (26) such that a passage section (102) for water is defined between the thermo-heating element (26) and the casing (22). To seal the electrical parts of the thermo-heating element (26) and to prevent damage, a sole sealed zone (100) filled with resin is created between the pump body (32) and the thermo-heating body (60). This resin filled sole sealed zone (100) obviates the need for using other less effective sealing elements and gaskets.

Abstract: An electronic heater structure includes a tube body, a heating wire disposed on the bottom of the interior of the tube body and a temperature controlling circuit. The temperature controlling circuit employs a thermosensitive resistor for detecting the temperature and controlling the activation time of the heating wire. The temperature controlling circuit employs a relay for controlling whether the heating wire is powered on or off. An upper cap of the tube body is integrally formed with a projecting chamber for placing a thermosensitive resistor therein. The relay and the thermosensitive resistor are isolated from each other by a circuit board. The tube body is vacuumized to remove the thermoconductive medium therein. Except for the heating wire, the temperature controlling circuit itself will not generate high heat and emit electro-magnetic interference and the detection portion with the thermosensitive resistor can extend into the water to accurately detect the water temperature.

Abstract: An energy efficient aquarium system with a separate cover wherein the lamp or lamps are located below the filters and filter ponds thus heating the filter pond bottom and sides to further heat the water contained in the filter ponds thus eliminating the need for a separate heater and further saving the energy required to heat the water as it flows into the aquarium. Floats each with a filter condition indicator bar are located in the filter ponds wherein the filter condition indicator bars extend through the cover and further indicate the condition of the filter as the water rises in the filter ponds due to the filters filling up with debris that restricts the flow of water passing through the filter; as the water rises in the filter ponds, the float rises and further causes the filter condition indicator to rise wherein it may easily be seen. When the filter condition indicator rises to a predetermined height, the owner of the aquarium would be given notice that the filters need to be changed.
