Operation principle of the present utility model and worked as follows:
During concrete the application, air inlet pipe 3 of the present utility model connects drainage container, and escape pipe 10 of the present utility model connects vacuum suction equipment.
After opening vacuum suction equipment, the pipette on the drainage container moves to liquid place to be absorbed, and liquid to be absorbed enters in the drainage container under suction function.During normal the use, pipe 6 in the gas that vacuum suction equipment sucks enters through air inlet pipe 3, air inlet 4 successively, in described between pipe 6 inwalls and the change in flow indication ball 8 is the gas communication space, gas is upwards circulation from this space, the gap that several openings 7 through interior pipe 6 upper ends enter between outer tube 5 and the interior pipe 6 flows downward, passage on bottle cap 29 enters in the bottle 1 then, flows out from venthole 12, escape pipe 10 at last.
Continuous attraction along with vacuum suction equipment, liquid in the drainage container is on the increase, after drainage container has been expired, liquid can be in pipeline flows to the bottle 1 of this utility model vacuum suction protection bottle, continuous rising along with liquid level in the bottle 1, low-density ball 13 can be at buoyancy of liquid effect float downward, when low-density ball 13 tops contact with bottle cap 2 lower surface, because bottle cap 2 interior bottom surface are made as the taper concave surface, club moves to place, summit under the guiding of taper concave surface, finally block venthole 12 lower open ends, the negative pressure that vacuum suction equipment produces will can not produce suction function in to drainage container, thereby when having avoided liquid too much, liquid can be drawn in the vacuum suction equipment, guarantees that vacuum suction equipment can be not contaminated.
After liquid in the drainage container is filled,, can carry out follow-up corresponding operation by changing drainage container or the liquid in the drainage container being poured out, easy to use.
In said process, be the space that is used for gas communication between pipe 6 inwalls and the change in flow indication ball 8 in described, increase gradually because the internal diameter of interior pipe 6 is bottom-up, along with flow velocity increases, change in flow indication ball 8 moves up, the space of gas communication becomes greatly gradually, so just can indicate the height of ball 8 to read the size of gas flow rate from change in flow.Promptly realize the adjusting of flow velocity size, read accurate gas flow rate by the position of indication ball 8 by the actual internal area of control valve 11 adjustments of gas circulation pipeline.
