As shown in Figure 5, embodiment 2 is with the difference of embodiment 1: described venthole 13 upper open ends are positioned at bottle cap 2 sidepieces, and described pressure regulating hole 12 outer openings are positioned at bottle cap 2 tops; Described venthole 13 upper open end inwalls are provided with female thread, and described escape pipe 10 adopts with venthole 13 upper open ends and is threaded.
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 pressure variation 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 13, 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 14 can be at buoyancy of liquid effect float downward, when low-density ball 14 tops contact with bottle cap 2 lower surface, because bottle cap 2 interior bottom surface are made as the taper concave surface, club is mobile to place, summit under the guiding of taper concave surface, finally block venthole 13 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, by changing drainage container or the liquid in the drainage container being poured out, can carry out follow-up corresponding operation, easy to use.
In said process, be the space for gas communication between pipe 6 inwalls and the pressure variation indication ball 8 in described, increase gradually because the internal diameter of interior pipe 6 is bottom-up, along with pressure increases, pressure changes indication ball 8 and moves up, the space of gas communication becomes greatly gradually, so just can change the size that the height of indication ball 8 is read gas pressure from pressure; Regulate the actual internal area of pressure regulating hole 12 by control valve 11, can adjust the gas flow that enters from pressure regulating hole 12, under the situation that the negative-pressure sucking of vacuum suction equipment remains unchanged, the gas flow that enters from pressure regulating hole 12 more many (aperture that is control valve 11 is more big), the gas flow that enters from air inlet pipe 3 is just more few, thereby can realize the accurate adjusting of vacuum suction pressure.
