Bubble generating assembly

1. A bubble generating assembly, comprising:

a housing having a motor, an air generator, tubing, and a bubble producing device associated therewith;

a source of bubble solution coupled to the bubble producing device via the tubing; and

a pump system provided inside the housing that draws bubble solution from the source to the bubble producing device;

wherein the bubble producing device includes a tubular member having an inner surface and an outer surface, and at least one flow opening in the tubular member, and the tubular member longitudinally aligned with the air generator so that air from the air generator will flow along both the inner and outer surfaces; and

a bubble solution flow path which extends from the source of bubble solution through the tubing to the interior of the tubular member, along the inner surface of the tubular member, and through the at least one flow opening to the outer surface of the tubular member such that bubble solution coats both the inner and outer surfaces.

2. The assembly of claim 1 , wherein the tubular member has a generally conical configuration.

3. The assembly of claim 1 , wherein the tubular member has a narrowed rear end and a front end that has a greater diameter than the diameter of the rear end.

4. The assembly of claim 1 , wherein the bubble producing device further includes a housing, with the tubular member retained inside the housing and having spacers for spacing the outer surface of the tubular member from the housing.

5. A bubble generating assembly, comprising:

a housing having a motor, an air generator and a bubble producing device associated therewith;

a source of bubble solution, and tubing that fluidly connects the source of bubble solution to the bubble producing device; and

a pump system provided inside the housing that draws bubble solution from the source to the bubble producing device;

wherein the bubble producing device includes:

a cylindrical housing having a cylindrical wall and an opening provided in the cylindrical wall;

a tubular member retained inside the cylindrical housing and having an inner surface and an outer surface, with at least one spacer positioned between the outer surface of the tubular member and the cylindrical wall, the tubular member longitudinally aligned with the air generator, and having a tubular wall with an opening extending through the tubular wall that is aligned with the opening of the cylindrical housing; and

a bubble solution flow path defined by the tubing, the opening in the cylindrical wall and the opening in the tubular wall that delivers bubble solution to the inner surface of the tubular member; wherein the tubular wall has a plurality of flow openings, and the bubble solution flow path further delivers bubble solution from the inner surface through one of the flow openings to coat the outer surface.

6. The assembly of claim 5 , wherein the tubular member has a generally conical configuration.

7. The assembly of claim 5 , wherein the tubular member has a narrowed rear end and a front end that has a greater diameter than the diameter of the rear end.

8. A method of forming bubbles, comprising:

a. providing a bubble generating assembly having:

a housing having a motor, an air generator, tubing, and a bubble producing device associated therewith;

a source of bubble solution coupled to the bubble producing device via the tubing; and

a pump system provided inside the housing that draws bubble solution from the source to the bubble producing device;

wherein the bubble producing device includes a tubular member having an inner surface and an outer surface, and at least one flow opening in the tubular member,

b. longitudinally aligning the tubular member with the air generator;

c. flowing bubble solution from the source of bubble solution through the tubing to the interior of the tubular member, along the inner surface of the tubular member, and through the at least one flow opening to the outer surface of the tubular member such that bubble solution coats both the inner and outer surfaces; and

d. blowing air along both the inner and outer surfaces.

9. The method of claim 8 , further comprising:

providing the bubble producing device with a cylindrical housing that surrounds the tubular member;

spacing the outer surface of the tubular member from the cylindrical housing; and

blowing air through the space defined by the outer surface of the tubular member and the cylindrical housing.

10. The method of claim 9 , further including:

flowing bubble solution from the tubing through an opening in the cylindrical housing and another opening in the tubular member to the inner surface of the tubular member.
