A bubble machine includes a housing, a liquid storage tank, a film forming device, a blower and a drive assembly. The liquid storage tank is connected to the housing, and the liquid storage tank is provided with a liquid storage chamber, a liquid discharge hole and a liquid return hole. The film forming device includes a mounting shell and a film covering body. The mounting shell is provided with a liquid collecting chamber, a first through hole, a second through hole and a film forming hole. The first through hole communicates the liquid collecting chamber with the liquid discharge hole. The second through hole communicates the liquid collecting chamber with the liquid return hole. The film forming hole penetrates the mounting shell and communicates with the liquid collecting chamber. The film covering body is provided in the liquid collecting chamber and is opposite to the film forming hole.

A bubble generating device that includes a housing having an outer surface and a motor and fan device positioned in the housing. The fan device may be operably coupled to the motor so that the motor, when activated, causes the fan device to rotate to generate an upward air stream within the housing. The bubble generating device may also include a trough for containing bubble solution and a spout protruding beyond the outer surface of the housing and configured such that bubble solution fed into the spout flows into the trough. A bubble generating assembly may be operably coupled to the motor, so that when the motor is activated the motor causes bubble generating members of the bubble generating assembly to move into contact with the bubble solution in the trough and then into alignment with the upward air stream to generate bubbles from the bubble solution.

The present invention is a bubble generating pool toy that generates air bubbles in a swimming pool in response to movement of levers provided on the toy. The toy is used by positioning it behind a user's back and grasping two levers which extend from each side of the toy. By repeated pushing the levers sideward away from each other in front of the user's chest and then allowing the levers to once again come together in front of the user's chest under the power of bellows that are outwardly biased, the bellows provided on the toy are alternately expanded and compressed. Expansion and compression of the bellows causes air to be pulled downward through tubes fitted with one-way valves and forces the air to exit the toy via bubble stones located under the surface of the water in the swimming pool, creating air bubbles in the water.

[Problem] To provide a presentation system that effectively uses the characteristic of a float body such as a bubble. [Solution] This presentation system 100 comprises: a tornado fan in which a plurality of blowers each perform blowing so that clockwise or counterclockwise air flow is generated in a presentation space surrounded by exhaust ports 114 of the plurality of blowers when viewed in a plan view; and a supply device 12 that supplies a float body such as a bubble into the presentation space. It is possible to cause an aggregate of bubbles to float in the vicinity of the center in the presentation space by means of a vortex air flow formed in the presentation space.

An automatic bubble blowing apparatus wearable on the head and having an inflatable ornamental skin. The inflatable ornamental skin is a non-tooled component which can be manufactured to have a variety of festive appearances. The apparatus has straps which can be used to secure the apparatus to the head of a user. Alternatively, the automatic bubble blowing apparatus can be utilized on a horizontal surface, such as a table, with the straps hidden under the apparatus. The automatic bubble blowing apparatus includes a power source, a surfactant solution reservoir, a fan for creating an air stream out an exit aperture, a mechanism for creating a surfactant film across the exit aperture, and an on-off switch which controls both power to the fan and sealing and unsealing of the exit aperture.
