Water aerating device for aquarium

Abstract

A water aerating device for an aquarium includes a container having an entrance and an exit arranged to allow water to flow into and out of a space of the container, and having a housing. A pumping device is disposed in the container for pumping the water into and out of the space of the container, and simultaneously for pumping air into the housing and the space of the container. A rotor is rotatably received in the housing, a receptacle secured to the rotor and having one or more paddle blades received in the space of the container, to pump the water. The receptacle includes a chamber having one or more fan blades to draw air into the receptacle.

1 . A water aerating device for an aquarium, said water aerating device comprising: 
 a container for being attached to the aquarium, and including a space formed therein, and including an entrance and an exit arranged to allow water to flow into and out of said space of said container, said container including a housing disposed therein and having a port, and    means for pumping the water into and out of said space of said container, and simultaneously for pumping air into said housing and said space of said container.    
   
   
       2 . The water aerating device as claimed in  claim 1 , wherein said pumping means includes a rotor rotatably received in said housing, a receptacle secured to said rotor and rotated in concert with said rotor and having at least one paddle blade extended therefrom and received in said space of said container, to pump the water into and out of said space of said container.  
   
   
       3 . The water aerating device as claimed in  claim 2 , wherein said rotor includes a casing rotatably received in said housing, and having a bore formed therein and communicating with said port of said housing, to allow air to flow into said receptacle via said bore of said casing.  
   
   
       4 . The water aerating device as claimed in  claim 3 , wherein said rotor includes at least one magnet engaged onto said casing.  
   
   
       5 . The water aerating device as claimed in  claim 3 , wherein said rotor includes a pipe engaged in said bore of said casing, and having an air passage formed therein, for communicating said receptacle with said port of said housing, to allow air to flow into said receptacle via said air passage of said pipe.  
   
   
       6 . The water aerating device as claimed in  claim 3 , wherein said casing includes at least one depression formed therein, said receptacle includes at least one projection extended therefrom and engaged into said at least one depression of said casing, to allow said receptacle and said casing to be solidly secured together.  
   
   
       7 . The water aerating device as claimed in  claim 2 , wherein said receptacle includes a chamber formed therein and having at least one fan blade provided therein, for drawing air into said receptacle when said rotor and said receptacle are rotated relative to said housing by said actuating means.  
   
   
       8 . The water aerating device as claimed in  claim 7 , wherein said at least one paddle blade of said receptacle includes a groove formed therein, to allow the air to flow out of said chamber of said receptacle and to flow into said space of said container.  
   
   
       9 . The water aerating device as claimed in  claim 2 , wherein said pumping means includes means for actuating said rotor and said receptacle to rotate relative to said housing, and to operate said at least one paddle blade of said receptacle to propel the water into and out of said space of said container.  
   
   
       10 . The water aerating device as claimed in  claim 9 , wherein said actuating means includes a stator disposed in said container to. actuate said rotor.  
   
   
       11 . The water aerating device as claimed in  claim 10 , wherein said stator is attached onto said housing.  
   
   
       12 . The water aerating device as claimed in  claim 10  further comprising a water resistive glue engaged onto said stator, to enclose and protect said stator.  
   
   
       13 . The water aerating device as claimed in  claim 1  further comprising a hose coupled to said port of said housing, to supply air into said housing via said port of said housing.  
   
   
       14 . A water aerating device for an aquarium, said water aerating device comprising: 
 a container for being attached to the aquarium, and including a space formed therein, and including an entrance and an exit arranged to allow water to flow into and out of said space of said container, said container including a housing disposed therein and having a port,    a rotor rotatably received in said housing,    a receptacle secured to said rotor and rotated in concert with said rotor, said receptacle including at least one paddle blade extended therefrom and received in said space of said container, to pump the water into and out of said space of said container, and    means for actuating said rotor and said receptacle to rotate relative to said housing, and to operate said at least one paddle blade of said receptacle to propel the water into and out of said space of said container.
