Floating device

Abstract

A levitation device is disclosed, which can be used with a heat source to heat cold air to generate hot air, and uses the hot air to provide buoyancy for airborne flight. The levitation device includes a main body, a base frame, and a stop material. The main body has a bottom opening, and its interior forms a cold air heating area and a hot air containing area, with airflow guided by cold and hot air channels. The base frame can house the heat source and support the main body. The stop material extends to a position adjacent to the hot air channels to prevent hot air from escaping from the bottom. This effectively reduces hot air loss, improves levitation stability and flight time, and is particularly suitable for applications requiring safety and environmental sustainability during sky lantern activities.

Claims

1. A buoyancy device, which can be coupled with a heat source to heat cold air to generate hot air, the buoyancy device comprising: A device body having a bottom opening at its bottom, and the interior of the device body having a hot air receiving area, a cold air heating area, a hot air flow channel, and a cold air flow channel, the hot air flow channel being connected to the bottom opening and extending to the hot air receiving area, and the cold air flow channel being connected to the bottom opening and extending to the cold air heating area; a device base frame for mounting the heat source, the device base frame being joined to the bottom of the device body to provide support for the bottom opening and to position the mounted heat source within the cold air heating area; And a stop material, which is connected to the equipment base; wherein, the cold air can flow into the cold air heating area through the cold air flow channel, so that the heat source can heat the cold air to generate the hot air, and cause the hot air to drift toward the hot air receiving area to provide buoyancy to the equipment body so that the equipment body floats. The stop material extends to a position adjacent to the hot air passage connecting to the bottom opening to prevent the hot air from flowing out of the hot air receiving area through the bottom opening.

2. The floating device as described in claim 1, wherein, The hot air containment area is higher than the cold air heating area.

3. The floating device as claimed in claim 1 further includes a counterweight material disposed on the device body to adjust the counterweight of the device body and prevent the floating device body from tilting, thereby reducing the extent to which hot air flows out of the hot air containing area through the bottom opening.

4. The floating device as described in claim 1, wherein, The bottom opening has a central region and a peripheral region. The central region is located at the center of the bottom opening, and the peripheral region is located at the periphery of the central region. The cold air flow channel is connected to the central region. The stop material avoids the central region to prevent the cold air from flowing into the cold air heating area through the cold air flow channel. The hot air flow channel is connected to the peripheral region. The stop material extends to a position adjacent to the peripheral region to prevent the hot air from flowing out of the hot air receiving area through the peripheral region.

5. The floating device as described in claim 4, wherein, The bottom opening periphery area has a left bottom opening periphery sub-area and a right bottom opening periphery sub-area. The left bottom opening periphery sub-area and the right bottom opening periphery sub-area are located to the left and right of the center area of ​​the bottom opening, respectively. The hot air flow channel connects the left bottom opening periphery sub-area and the right bottom opening periphery sub-area. The stop material extends to a position adjacent to the left bottom opening periphery sub-area and the right bottom opening periphery sub-area to prevent the hot air from flowing out of the hot air receiving area through the left bottom opening periphery sub-area and the right bottom opening periphery sub-area.

6. The floating device as described in claim 5, wherein, The cross-sectional lengths of the outer sub-region of the left bottom opening, the outer sub-region of the right bottom opening, and the center region of the bottom opening can be substantially the same, or configured in a preset proportion to form airflow separation and balance.

7. The floating device as described in claim 4, wherein, The area surrounding the bottom opening is a hollow ring structure.

8. The floating device as claimed in claim 1, further comprising a stop support that provides support to the stop material so that the stop material can stop the hot air from flowing out of the hot air receiving area through the bottom opening on a transverse stop surface, the transverse stop surface being transversely extended.

9. The floating device as claimed in claim 1, further comprising a stop support that provides support to the stop material so that the stop material can stop the hot air from flowing out of the hot air receiving area through the bottom opening on a longitudinal stop surface, the longitudinal stop surface being longitudinally extended.

10. The floating device as claimed in claim 1, further comprising a stop support that provides support to the stop material so that the stop material can stop the hot air from flowing out of the hot air receiving area through the bottom opening on an inclined stop surface, the inclined stop surface being inclined.
