Document Type and Number:
WIPO Patent Application WO/2021/147159
Kind Code:
A1
Abstract:
A bubble machine producing bubbles by means of waving comprises a fan (3), an airflow path (5), and a bubble outlet. An airflow generated by the fan (3) reaches the bubble outlet via the airflow path (5), and is blown into a liquid film at the bubble outlet so as to produce a bubble that can be maintained at the bubble outlet. A check valve (6) is provided in the airflow path. The bubble machine producing bubbles by means of waving can produce bubbles for stage effects or for the entertainment of children, and can maintain a bubble at the bubble outlet for a long time without having to keep the fan turned on.
