| description | A negative pressure bottle capable of preventing liquid leakage comprises a bottle body and a stomach tube connecting tube. The device is characterized in that the upper end of the bottle body is movably connected with the stomach tube connecting tube through a connecting structure; a bottle opening of the bottle body is of a double-layer structure and comprises an inner first bottle opening body and an outer second bottle opening body, and a containing cavity capable of containing liquid is formed between the first bottle opening body and the second bottle opening body. A through hole communicated with the interior of the bottle body is formed in the accommodating cavity; by means of the mode, liquid flowing out of the exhaust hole still flows back into the bottle body after passing through the containing cavity and the through hole, the problem that in the prior art, a negative pressure bottle is prone to liquid leakage and pollutes air is solved, and drainage liquid can be conveniently and uniformly metere |
