Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a solution for an infusion bottle venting device.

An infusion bottle vent comprising:

the protection sleeve 2 is fixed with a fixing ring 23 on the inner wall of the protection sleeve 2;

a sliding column 3, the sliding column 3 is arranged in the protective sleeve 2, the sliding column 3 can move in the protective sleeve 2,

the ventilation needle 6 is set to be hollow tubular, the ventilation needle 6 comprises an insertion part 61, an intermediate connection part 62 and an air outlet part 63, the insertion part 61 penetrates through the sliding column, the insertion part 61 and the air outlet part 63 are arranged in parallel, the insertion part 61 and the sliding column 3 are fixed together, a connection side groove 24 for the intermediate connection part 62 to penetrate through is arranged on the side wall of the protection sleeve 2, and the insertion part 61 can penetrate through the fixing ring 23 to move out of the protection sleeve 2 by moving the intermediate connection part 62.

The insertion part 61 is completely arranged in the protective sleeve 2, so that the protective function can be achieved, and the phenomenon that a person is hurt by a needle of the insertion part 61 is avoided.
