Abstract: The disclosure provides a liquid taking device and a liquid taking method. The liquid taking device comprises a liquid taking bottle, a heavy ball and liquid taking ropes. The liquid taking bottle has a first mouth and a bottom opposite to the first mouth. The heavy ball is arranged in the liquid taking bottle. The liquid taking device can be controlled to reach different depths under the ground by the action of two liquid ropes. When the first mouth of the bottle is placed facing downward, the heavy ball blocks the first mouth of the bottle under its own gravity to prevent liquid leakage; when the first mouth of the bottle is turned upwards under the action of the liquid taking rope, the heavy ball falls onto the bottom of the bottle, such that an external liquid can flow into the liquid taking device, which has a good practical utility.

Abstract: The floor member, in one embodiment of the invention, is a floor member unit having a surface declination at the periphery of a top surface and extending downwardly to a peripheral beveled edge, and intersecting with the beveled edge between the top surface and a bottom surface. The surface declination can be curved or uncurved. In another embodiment of the invention the floor member unit is laminated in offset relationship to an underlayer of the same size and shape as the floor member unit. In either embodiment, the floor member can be formed as a floor tile or a floor plank.
