Negative pressure ball pouring needClamp the hose, remove the liquid bottle to pour out the liquid inside, then reconnect the bottle and release the clamp on the hose.
Negative pressure attraction device consists of regulator, liquid collection bottle, hose, etc.. There are two hose ports on the liquid collection bottle, one connecting to the negative pressure terminal, and one connecting to the working chamber. When the negative pressure terminal is connected, the negative air pressure will be generated in the liquid collection bottle, and the negative pressure will guide the dirt (such as dirty blood, phlegm, etc.) to flow into the liquid collection bottle from the other hose.
Negative pressure utilization
Negative pressure utilization is very common, people often make a part of the space in a negative pressure state, we can use the ubiquitous atmospheric pressure for our effectiveness. For example, when people breathe, when the lungs are in a state of expansion of negative pressure, the formation of a pressure difference between the inside and outside of the lungs, fresh air is pressed into the lungs.
