Detailed Description
A preferred embodiment of the present utility model is described below with reference to fig. 1. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.
The utility model provides a sustainable inflatable unfolding cylinder which comprises an unfolding cylinder 1 and a cylinder cover 6, wherein the unfolding cylinder 1 is made of colorless transparent glass, is a cylinder with the height of about 25cm, is open at the top and has large inner cavity capacity, and the inner cavity condition of the unfolding cylinder 1 can be clearly observed. The top of the unfolding cylinder 1 is provided with a cylinder cover 6, the bottom of the cylinder body of the unfolding cylinder 1 is provided with an air inlet 2, and the unfolding cylinder is arranged at a position about 5cm away from the bottom surface. The air inlet 2 is connected with an air supply device 5 through a rubber hose 3, and the air density is higher than that of air or similar air. The rubber hose 3 serves as an inflation line, forming a passageway through which gas can be continuously inflated. The top end of the cylinder cover 6 is movably connected with a hook 9 through an adjusting screw 8. The height of the hook 9 can be adjusted by the adjusting screw 8, and the hook 9 is used for hanging test paper.
The outer surface of the cylinder opening of the unfolding cylinder 1 is provided with threads, the inner surface of the cylinder cover 6 is provided with threads, and the two are locked through a thread structure, so that the cylinder cover 6 is prevented from being jacked up too fast in gas flow rate. The top end of the inner wall of the cylinder cover 6 is provided with a sealing rubber strip, so that a good sealing effect can be achieved. The top end of the cylinder cover 6 is provided with a non-return valve 7. The check valve 7 only allows the gas in the expansion cylinder 1 to flow outwards, prevents the gas from flowing reversely, and is used for gradually evacuating the air in the expansion cylinder 1 and improving the gas concentration in the expansion cylinder 1. When the density of the gas is higher than that of the air, the gas enters the cylinder from the air inlet 2 below the unfolding cylinder 1 side, and the air in the upper layer in the cylinder is discharged through the check valve 7 under the condition that the air supply device 5 continuously supplies the air because the density of the gas is higher than that of the air, so that the concentration of the gas in the cylinder is controlled and regulated. The air inlet 2 is provided with a sealing plug to avoid the leakage of the air in the cylinder body of the unfolding cylinder 1. The rubber hose 3 is provided with a pressure valve 4. The pressure valve 4 can control the flow rate of the gas output and can automatically adjust the speed of the gas according to the requirement. The air supply means 5 include, but are not limited to, an air bag or a gas cylinder. The fixed air supply device 5 can be selected according to the self condition, and an air bag or an air bag can be selected if the portable device is required to be carried; if there is a longer gas supply requirement, a gas cylinder with a larger volume can be selected.
