Abstract

The invention relates to a sealed milk powder cover. The sealed milk powder cover comprises a cover body; the cover body sleeves an opening of a milk powder tank; a cavity is formed in the cover body;a vacuumizing device and an automatic deflation device are mounted in the cavity, and are electrically connected with an electric control device; a sealing cover is arranged at the bottom of the cavity; a sealing ring is arranged in the sealing cover; the sealing ring is a flexible elastic hollow sealing ring; a concave-convex structure is arranged on the side surface of the sealing ring; an airpump in the milk powder cover is started to vacuumize the milk powder tank for permanent preservation; when the milk powder tank needs to be opened, the deflation valve is opened to relieve a vacuum state; and the sealed milk powder cover is conveniently used, and effectively solves the problem of easy wetting after opening of the milk powder tank.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing milk powder cover. Background technique [0002] Milk powder is a common food in daily life. For milk powder, which is used in a small amount each time and lasts for a long time per can, there are higher requirements for the sealing of the packaging. When the package of milk powder is opened for the first time, air will enter the package, making it difficult to seal, and it is easy to be affected by moisture, oxidation and agglomeration, which will affect the quality of milk powder. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a sealed milk powder cap with good sealing performance. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] A sealed milk powder cover, including a cover body, the cover body is set on the opening of the milk powder t...
