Silent device for submerge pump of aquarium

Abstract

This invention discloses a silent device of submerge motor for aquarium, comprising a main body, a plurality of partition boards arranged in the interlaced longitudinal and transversal directions, an open passage individually disposed at the upper and lower sections of the longitudinal and transversal partition, an air inlet and an air outlet disposed at the bottom and the top of the main body respectively, a filter cotton and a netted cover disposed at the top the main body, such that the air outlet is connected to the air inlet duct of a submerge motor. After the air enters the main body through the air inlet, the air form upper and lower turnabout passages by the interlaced partition boards to lengthen the conveyance path and diminish the molecular collision in order to achieve the silent effect.

1 . an improved silent device for submerge pump motor of aquarium, comprising: 
 a main body, having interlaced partition boards in transversal and longitudinal directions and an open passage disposed respectively at the top and the bottom of said transversal partition board and longitudinal partition board; an air inlet and an air outlet disposed at one side of the bottom and the top of said main body respectively; a fixing hole disposed at each of the four comers of a rear surface for fixing the same number of vacuum cups;    a fixing base with a transversal “H” shaped cross section, and its side having a through hole corresponding to said air inlet of said main body and a plurality of protruded brackets having partition arrangement disposed at the bottom;    a piece of filter cotton, disposed under said fixing base; and    a netted cover, disposed under said filter cotton and having a footer disposed at bottom of said netted cover;    by the assembling of foregoing elements, the air outlet of said main body for connecting an air incoming duct of a submerge pump allowing air to enter from the air inlet, and then passing through a turnabout passage formed by said partition boards in order to elongate the conveyance path and diminish the collision of the molecules in the air, and thus attaining the silent effect.    
   
   
       2 . The improved silent device for submerge pump motor of aquarium of  claim 1 , 
 wherein said transversal and longitudinal partition boards in said main body is set at a position selected one from having its top lower than the top of said main body and its bottom higher than the bottom of said main body to define an upper open passage and a lower open passage.
