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.

The first embodiment is as follows: referring to fig. 1, 2, 3, 5, 6 and 7, a liquid corrosion prevention bottle cap comprises an inner collar and an outer sleeve seat 7;

the inner sleeve ring and the outer sleeve seat 7 are made of hard plastics such as ABS, PE, PP, PVC and the like, and the materials of the inner sleeve ring and the outer sleeve seat can also be selected from other metal or nonmetal materials such as stainless steel, glass and the like according to requirements.

The inner lantern ring comprises an exhaust ring 1, an exhaust ring connecting ring 2, a waterproof breathable film 3, a clamping strip 4, a convex ring 5 and a net rack 6, wherein the outer diameter of the exhaust ring connecting ring 2 is smaller than that of the exhaust ring 1, and the exhaust ring connecting ring and the net rack are integrally arranged on the upper side of the exhaust ring 1;

the net frame 6 is integrally arranged at the inner side of the junction of the exhaust ring 1 and the exhaust ring connecting ring 2, in order to ensure air permeability, the net frame 6 is cross-shaped, and the net frame 6 can also adopt a net structure so as to improve the strength of the bottle pad;

the waterproof breathable film 3 is attached to the lower side of the net rack 6 and covers the holes of the net rack 6, so that the distance between the waterproof breathable film 3 and the bottom of the outer sleeve seat 7 is large, the waterproof breathable film 3 can be prevented from being polluted or impacted by liquid, the waterproof breathable film 3 is attached to the lower side of the net rack 6, the net rack 6 can reinforce the waterproof breathable film 3, and the service life of the waterproof breathable film 3 can be prolonged;

the inside card strip 4 of a plurality of inserts tight fit in outer cover seat 7 of the outside circumference interval arrangement of exhaust ring 1, the steadiness that interior lantern ring and outer cover seat 7 are connected is guaranteed, the lower extreme protrusion exhaust ring 1's of card strip 4 lower surface, and the upper end outside of exhaust ring go-between 2 is provided with bulge loop 5, and bulge loop 5 is used for being connected of bottle pad and thread cover 9.

A plurality of arc-shaped liquid discharge holes 8 are formed in the bottom of the outer sleeve seat 7 at intervals in the circumferential direction, and the boundary line between the outer edge of each liquid discharge hole 8 and the inner side surface and the inner bottom surface of the outer sleeve seat 7 coincides, so that liquid deposition inside the outer sleeve seat 7 can be reduced.
