## Abstract

A bubble blower tube includes a blower tube defining opposing mouthpiece and an outlet, a check valve mounted in the outlet to prohibit flowing of air or bubble fluid from the outlet toward the mouthpiece, a bubble-forming tube having a connection end connected to the periphery of the blower tube and a bubble-forming end shaped like a trumpet and suspending outside the blower tube, and a bubble fluid retaining ring located at the bubble-forming end of the bubble-forming tube and defining an outer bubble fluid retaining part and an inner bubble fluid retaining part.

## Claims

### Claim 1

A bubble blower tube, comprising:
a blower tube (1) comprising a mouthpiece at one end thereof, an outlet at an opposite end thereof;
a check valve mounted in said outlet for allowing air to pass from said mouthpiece toward said outlet and prohibiting air from flowing through said outlet toward said mouthpiece;
a bubble-forming tube comprising a connection end integrally connected to the periphery of said blower tube in a flush manner, a bubble-forming end shaped like a trumpet and suspending outside said outlet of said blower tube, a fluid storage chamber defined between said outer perimeter of the outlet of said blower tube and an inner perimeter of said bubble-forming tube, and an annular stop flange extending around an outer perimeter of said bubble-forming tube between said connection end and said bubble-forming end; and
a bubble fluid retaining ring comprising an outer bubble fluid retaining part and an inner bubble fluid retaining part, said outer bubble fluid retaining part comprising a plurality of main bubble fluid retaining ribs and main bubble fluid grooves alternatively and radially arranged on an end edge of said bubble-forming end of said bubble-forming tube, said inner bubble fluid retaining part comprising a plurality of supplementary bubble fluid retaining ribs and supplementary bubble fluid grooves alternatively and axially arranged around an inner perimeter of said bubble-forming end of said bubble-forming tube, said supplementary bubble fluid grooves being respectively connected to said main bubble fluid grooves.

### Claim 2 (depends on 1)

The bubble blower tube as claimed in claim 1, wherein said blower tube further comprises a positioning member mounted in said outlet, said positioning member comprising a positioning hole, and a rack connected between an outer wall of said positioning member and an inner wall of said outlet; said check valve comprises an elastically deformable flap stopped at said outlet and a positioning rod perpendicularly extended from a bottom wall of said elastically deformable flap and positioned in said positioning hole.
