Bubble blower

Abstract

A bubble blower includes an open frame-shaped bubble blower body defining a main solution-retaining portion, a peripheral rib extending around the main solution-retaining portion and a main passage between the main solution-retaining portion and the peripheral rib, and bubble-blowing rings spaced along an inside wall of the open frame-shaped bubble blower body each defining an inner solution-retaining portion, an outer solution-retaining portion connected with the main solution-retaining portion of the bubble blower body, a sub passage between the inner solution-retaining portion and the outer solution-retaining portion in fluid communication with the main passage of the bubble blower body to form a solution supply passage.

What the invention claimed is: 
     
         1 . A bubble blower, comprising:
 a bubble blower body in form of an open frame, said bubble blower body comprising an opening and a main solution-retaining portion extending around said opening; and   a bubble-blowing rings respectively extended from an inside wall of said bubble blower body and suspending in said opening of said bubble blower body, each said bubble-blowing ring comprising a center opening, an inner solution-retaining portion extending around said center opening, and an outer solution-retaining portion extending around an outside wall thereof and suspending in the opening of said bubble blower body, the outer solution-retaining portions of said bubble-blowing rings being connected with said solution-retaining portion to form an enclosed solution-retaining loop.   
     
     
         2 . The bubble blower as claimed in  claim 1 , wherein said bubble blower body further comprises a peripheral rib extending around said main solution-retaining portion, and a main passage defined between said main solution-retaining portion and said peripheral rib; each said bubble-blowing ring further comprises a sub passage defined between the inner solution-retaining portion and outer solution-retaining portion thereof, the sub passages of said bubble-blowing rings being kept in fluid communication with said main passage of said bubble blower body to form a solution supply passage.
