Abstract

The invention discloses a self-adaption two-way inverse suction prevention device. The device comprises a bottle body, two air pipes, a siphon, the two air pipes are respectively connected to an air inlet end and an air outlet end, the siphon is arranged on the bottom of the bottle body, an inner pipe port of the siphon is provided with a plug which is pulled by a floating ball, the floating ballis connected with the bottom of the bottle body through a spring, the floating ball moves up and down with the amount of liquid in the bottle body, and drives the plug to move, and controls the opening and closing of the inner pipe port of the siphon. The control method is simple, convenient, and easy to achieve.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to an adaptive bidirectional anti-suckback device. Background technique [0002] In chemical experiments, liquid sucking back will have adverse effects on experiments, such as bursting of glass instruments, contamination of reaction reagents, etc. Therefore, certain measures must be taken in related experiments to prevent sucking back of absorbing liquid. Existing anti-suckback bottles usually adopt a short-in and long-out connection mode. If a connection error occurs, it cannot prevent liquid from being sucked back. Contents of the invention [0003] In view of this, an adaptive two-way anti-suckback device is provided, the air inlet pipe and the air outlet pipe of the anti-suckback bottle can be connected interchangeably, and the operation method is simpler, more convenient and easy to implement. [0004] The purpose of the present invention is achieved through the f...
