In a support device for aquarium accessories including a first fixing element appliable on the inner surface of a wall of an aquarium and a sustaining element for an accessory supportable by the first fixing element, the first fixing element has a concave cap and the sustaining element has a convex cap housable at least partially inside the concave cap. Furthermore, the support device includes a cap-shaped first magnetic or ferromagnetic element, the first fixing element includes a second magnetic or ferromagnetic element, and the convex cap of the sustaining element is interposed between the concave cap of the first fixing element and the first magnetic or ferromagnetic element so that, due to magnetic attraction between the first magnetic or ferromagnetic element and the second magnetic or ferromagnetic element, the sustaining element is supported by the first fixing element and, at the same time, it is rotationally movable.

Support device for aquarium accessories

Filtering device () to draw water from an aquarium and the like and make water circulate inside, including a container () comprising a first housing portion () having a first inlet () and a second inlet () for the entry of water taken from the aquarium into the first housing portion () which is able to contain at least one filter for filtering water, further including a flow control device () having an entry () for taking water from the aquarium and it has two operating positions, a first operating position or filtering position wherein the entry () is in communication with the first inlet (), so that water taken from the aquarium is put into the first housing portion (), passes through the first inlet (), is filtered and then is put back into the aquarium, and a second operating position or cleaning position or backwash position, wherein the entry () is in communication with the second inlet (), water taken from the aquarium enters into the first housing portion () through the second inlet (), so reversing the flow of water inside the first housing portion () and then is discharged so cleaning the filters.

A synchronous electric motor for operating a pump includes a motor body, a stator and a rotor coupled to an impeller of the pump. The motor also comprises a cylindrical element that extends towards the inside of the motor body from one of its outer walls so as to define a first cylindrical cavity open to the outside to insert inside the rotor, wherein the rotor has a circular cross section essentially corresponding to the inner section of the cylindrical element so that the rotor is in contact with the cylindrical element and then there is a friction between the rotor and the cylindrical element when the rotor rotates, and the rotor is shaftless and axially and directly coupled to the impeller of the pump.

A magnetic support () for aquariums includes a first and a second support element (), each of them having a magnet () so that by coupling the first and second support elements () by interposing an aquarium wall () between them, the attracting magnetic force operating between the two magnets () locks the two support elements (). Each support element () comprises a flat element () made up of flexible material having a peripheral projecting lip (), so that when the two support elements () are coupled together by interposing the wall (), the peripheral projecting lips () are flattened against the wall (), thus creating a suction effect.

In an aerator () for aquariums and ponds there is an impeller () operated by an electric motor () having a first entry () for the intake of water, a second entry () for the intake of air and an exit () where the water and air flow comes out, the impeller (), when it is operated, sucks water from said first entry (), creates a lower pressure which sucks air from said second entry () and mixes said sucked air with water generating a flow which comes out from the exit ().

Rotating aerator for aquariums and ponds

In a water distributor device for aquariums, ponds and the like, comprising a main body () wherein an impeller () is inserted, the impeller () is rotated by entering water and is kinematically connected by gears to a nozzle () rotatably mounted on the main body () and the gears continuously rotates said nozzle ().

Aquarium heater

An automatic distributor of fish food for aquariums comprising a rotating container ( ) for fish food, a cover ( ), an electric motor ( ) and transmission ( ) for transmitting the motion to the rotating container ( ). At the bottom ( ) of the container ( ) there is an housing ( ) for the electric motor ( ) and the transmission ( ), and furthermore the rotation axis of the rotating container ( ) is aligned with the motor axis of the electric motor ( ).

Automatic distributor of fish food for aquariums

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