A motor powers the siphoning mechanism, the drive mechanism, and the fan, such that separate continuous bubble streams are created simultaneously.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to bubble blower machines and more particularly to a bubble blower machine capable of creating two continuous bubble streams simultaneously.

2. DESCRIPTION OF PRIOR ART INCLUDING INFORMATION DISCLOSED UNDER 37 CFR 1.97 AND 1.98

U.S. Pat. No. 8,636,557 discloses a hand-held bubble generating apparatus including a housing with a non-spill reservoir for storing bubble generating liquid. A tube carries the bubble generating liquid from the reservoir to a bubble assembly support inside the housing. The bubble assembly support has a main rotational bubble ring made up of a plurality of smaller individual rings spaced around the outer circumference of the main rotational bubble ring.
When the main rotational bubble ring is rotated proximate to and across a liquid dispensing section, each of the smaller individual rings receives enough bubble generating liquid to form a film across the ring. By rationing the amount of bubble liquid released on each individual ring, the device can incorporate a closed, non-spill reservoir. A stream of bubbles is produced when air is generated and blown through the film of bubble generating liquid on each of the individual rings of the main rotational bubble ring.
Although the bubble generating device of Pat. No. U.S. Pat. No. 8,636,557 works very well, it can only generate one continuous bubble stream at a time. The present invention is designed to overcome that limitation by providing a bubble film forming mechanism with two main rotational bubble rings, each having a plurality of smaller individual blowing rings. Each of the main rotational rings is capable of creating a continuous bubble stream. In this way, two continuous bubble steams can be created simultaneously.
This made possible by using only a single motor with modifications on the gears structure as well as the bubble siphoning feeding tubing. A major benefit of this design is that with the present invention, twice the number of bubbles are generated as compared to the amount produced in the patented bubble generating device, while at the same time keeping the design compact and easy for kids to carry around in an outdoor environment.

BRIEF SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, a bubble generating apparatus is provided including a housing having first and second end portions. First and second rotational ring structures are rotatably seated in the housing and disposed proximate to an opening defined in the second end portion of the housing.

DETAILED DESCRIPTION OF THE INVENTION

As seen in FIGS. 1, 2 and 3 , the bubble generating apparatus includes a housing, generally designated 10. Housing 10 has a handle portion 12 and a barrel portion 14. Barrel portion 14 has a front end 16 and a rear end 18.
A first rotational ring structure 20 is rotatably seated in a faceplate 22 which forms the front 16 of housing 10. A second rotational ring structure 24 is also seated in faceplate 22 at a location spaced from and in substantially the same plane as first rotational ring structure 20.
Each of the first and second rotational ring structures 20, 24 is formed of a plurality of individual rings 26. Rings 26 are arranged circumferentially within the rotational ring structures.
Handle portion 12 of housing 10 is hollow and functions as a reservoir to store bubble generating liquid. The handle is coupled to the housing by an internally threaded cap-like connector 28 designed to mate with the externally threaded top portion of handle 12. The handle is removable to allow the bubble generating liquid to be replenished.
A fan 30 is located in an opening in the rear 18 of the housing. When rotated, fan 30 will create an airflow through the housing. The fan is covered by a cage 19.
FIGS. 4, 5 and 6 show the liquid dispensing section of the blower is disposed proximate to the opening at the front end 16 of the housing. The liquid dispensing section includes a first conduit 32 and a second conduit 34. Each of the conduits 32, 34 has an outlet connected to the faceplate 22 to deliver bubble generating liquid onto the plurality of individual rings 26 of a different one of the first and second rotational ring structures 20, 24. That creates a film of bubble generating liquid across the plurality of individual rings 26 of each of the first and second rotational ring structures 20, 24.
When actuated, a siphoning mechanism 36 draws the bubble generating liquid from the reservoir in handle portion 12, through a supply conduit 38 and then through the outlets in first and second conduits 32, 34. In this way, the bubble generating liquid is provided to each of the first and second rotational ring structures 20, 24 and more particularly, to the individual rings 26 of each of the first and second rotational ring structures 20, 24.
Within the housings is a drive mechanism which rotates the first and second rotational ring structures. The drive mechanism includes a gear assembly, generally designated 40, which connects a motor 42 to each of the rotational ring structures 20 and 24. Motor 42 is situated within the housing near the rear end 18 of the housing, adjacent fan 30.
Motor 42 is energized by batteries (not shown) situated within a compartment in the top portion 44 of the housing. The battery compartment can be accessed through a removable cover 46 to replace the batteries. A pushbutton 48, accessible from the side of the housing, operates a switch within the housing (not shown). The switch electrically connects motor 42 with the batteries when pushbutton 48 is depressed.
As best seen in FIG. 7 , the front portion of gear assembly 40 includes a central gear 50 which is connected to the rotational ring structures 20 and 24 through gears 52 and 54, respectively. Rotational ring structures 20 and 24 each have gear teeth 56, 58 respectively situated around their exterior surface. Gear 52 engages the circumferential gear teeth 56 of rotational ring structure 20. Gear 54 engages the circumferential gear teeth 58 of rotational ring structure 24.
Motor 42 is connected to and powers siphoning mechanism 36, drive mechanism gear assembly 40 including central gear 50, and fan 30 such that the dual head blower can create two separate continuous bubble streams simultaneously, as illustrated in FIG. 9 .
While only a single preferred embodiment of the present invention has been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
