the utility model provides a prevent suck-back cushion flask, includes the bottle, and the inside of bottle is provided with the interlining, the upper surface of bottle is provided with the bottleneck, and the upper surface of bottleneck is provided with the intake pipe, and the upper surface of bottleneck still is provided with the outlet duct, and the one end of outlet duct is provided with the gas outlet, and the inside of gas outlet is provided with the pellicle.
As a still further scheme of the utility model: the material of bottle is organic glass, can guarantee the transparency of cushion flask and improve the shock resistance of cushion flask.
As a still further scheme of the utility model: the material of interior intermediate layer is polyvinyl chloride, can strengthen the acid and alkali corrosion resistance degree of buffer bottle.
As a still further scheme of the utility model: the outside of bottleneck is provided with the sealing washer, is convenient for people to carry out the experiment work.
As a still further scheme of the utility model: the air outlet pipe and the semipermeable membrane form a connecting structure through the air outlet, so that the buffer bottle is not easy to suck liquid backwards.
As a still further scheme of the utility model: one end of the air outlet pipe is provided with an external thread, and an internal thread is arranged inside the air outlet, so that the air outlet can be conveniently installed.
As a still further scheme of the utility model: the air outlet pipe and the air outlet form a fixed structure through threads, so that the semipermeable membrane is fixed conveniently.
Compared with the prior art, the utility model has the beneficial effects that:
1. according to the buffer bottle, the bottle body made of organic glass and the inner interlayer made of polyvinyl chloride can ensure the transparency of the buffer bottle, and meanwhile, the acid-base corrosion resistance and impact resistance of the buffer bottle are greatly improved, so that the buffer bottle is not easy to damage, the working efficiency of people is improved, and the use requirements of people are met.
2. According to the utility model, through the semi-permeable membrane arranged at the air outlet, air can pass through the semi-permeable membrane, but liquid cannot pass through the semi-permeable membrane, so that the buffer bottle is not easy to suck back liquid, and the purpose of protecting the sampler is achieved.
