US Patent 10363492 Bubble machine for producing vertical bubbles

A bubble machine has a fan assembly that has a fan housing, and a fan coupled to the fan housing. A bubble dispenser is disposed above the fan housing, and has a mounting section that is secured inside the fan housing, and a bubble solution collection section covering the fan below. The housing, the mounting section and the bubble solution collection section define at least one space through which air generated by the fan can flow upwardly. A bubble wand assembly has a plurality of bubble wands that are disposed above the bubble dispenser in a manner such that each of the plurality of bubble wands is rotated over the bubble solution collection section to be coated with bubble solution, and then rotated over the at least one space so that air from below can be blown through the bubble wand to generate bubbles.
