The invention has the advantages that:
the test tube is when disposing solution, annular housing floats in the liquid level top, shake even in-process, the bubble of production floats on the liquid level, and the gathering is in annular housing inner circle, inertial force drives counter weight ball reciprocating sliding in annular housing, slide the in-process and stretch and extrude elasticity gasbag repeatedly, elasticity gasbag is when being stretched, pump to elasticity gasbag through the floating bubble in the defoaming pipe with the liquid level top in, elasticity gasbag is when being extruded, internal pressure increases, make the bubble break, and discharge by the defoaming pipe once more, thereby play good defoaming effect.
In the process that the counterweight balls slide in the annular shell in a reciprocating mode, the counterweight balls are close to and far away from each permanent magnet periodically, and then the permanent magnets receive attraction and repulsion force which change periodically, the defoaming needle is driven to stretch and retract repeatedly, bubbles among the annular shells are punctured, the defoaming effect is further improved, and the experiment is prevented from being influenced.
Preferably, the annular housing is made of plastic and has a density less than that of water.
Preferably, the embedded closed coil that is equipped with many circles of heliciform winding and puts that is of annular housing's lateral wall, install the piece that generates heat on annular housing's the inside wall, closed coil's both ends are linked with the positive pole and the negative pole coupling of the piece that generate heat respectively, and the counter weight ball is at the reciprocal slip in-process, and closed coil continuously cuts the magnetic induction line of counter weight ball and produces induced-current, for the piece power supply that generates heat, annular housing surface temperature rises for bubble surface moisture evaporates, thereby promotes the bubble and breaks fast.
