若要調整外箱體在水中所受的浮力，使用者可透過進水管加水填充於容置空間來調整內箱體的重量，使外箱體可透過內箱體的容置空間的蓄水量來控制外箱體整體的下沈幅度

結果 (英文) 1:

To adjust the outer box suffered buoyancy in the water, the user can fill with water through inlet pipe accommodating space within the housing to adjust the weight of the outer casing can be water holding capacity of the inner space through the housing controlling the entire outer box sinking amplitude

結果 (英文) 2:

To adjust the buoyancy of the outer box in the water, the user can adjust the weight of the inner box by filling the capacity space with water from the inlet pipe and water, so that the outer box can control the overall lowering of the outer box by storing water through the storage of the inner box's capacity.

結果 (英文) 3:

In order to adjust the buoyancy of the outer box in the water, the user can adjust the weight of the inner box by filling the water into the holding space through the water inlet pipe, so that the outer box can control the overall sinking range of the outer box through the water storage of the holding space of the inner box
