| 摘要 |
The present invention relates to a controllable hot-air balloon. A support (3) on which a heating device such as a candle (1) is placed is formed in the lower part of a box formed of paper or plastic. One or more spray nozzles are formed in one or more directions and spray hot air in the hot-air balloon to the side of the upper part or the upper part of the hot-air balloon. A valve is formed on a hole formed on a hot-air balloon main body of the spray nozzle facing the outside from the inside of the hot-air balloon. So, a solenoid valve, a step motor, and a servo motor are wirelessly controlled to open the valve to spray the heat of the hot-air balloon to a desired direction. Therefore, the controllable hot-air balloon can move forwards in a selected direction among all directions and can ascend and descend. |
