Abstract

The invention aims to provide a vacuum cover for a storage container, wherein the vacuum cover for the storage container is simple in structure and capable of conducting immediate vacuumizing or immediate pressure relief on a wide-mouth storage container. The vacuum cover for the storage container comprises a cover body. The portion, close to the edge, on the lower side of the cover body is provided with a groove matched with a mouth of the storage container in a surrounding manner. A first seal ring is arranged in the groove. The cover body is further provided with a cavity. The cavity is provided with a vacuumizing pressing block in a matched manner through a first reset spring. The vacuumizing pressing block and the cavity cooperate and form a vacuumizing chamber. The bottom of the cavity is provided with a vacuumizing opening communicating with an inner cavity of the storage container. The vacuumizing opening is provided with a one-way valve in a matched manner. The vacuumizing pressing block is pressed circularly, and then the inner cavity of the storage container is vacuumized. The cover body is further provided with a pressure relief device. The outer end of the pressure relief device is exposed out of the cover body. The pressure relief device is pressed, and then the pressure in the storage container recovers to the normal pressure. The vacuum cover for the storage container is applied to the field of vacuum devices.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to a storage tank vacuum cover used on a storage tank, especially a wide-mouth storage tank, for instant vacuuming to form a vacuum environment. Background technique [0002] Storage tanks can be seen everywhere in life, such as large storage tanks, small bottle storage tanks, etc. used to store dry goods in stores or supermarkets, and storage tanks used to store dry food at home. In the prior art, these storage tanks all without exception just utilize bottle caps to directly cover the storage tanks to play a storage function. In this way, after the bottle cap is closed, part of the air will remain in the tank, which will cause the food in the tank to be stored for too short a time or even cause food corruption, and it will not be able to preserve it. In addition, for small bottle-mouth storage tanks, there is also a method of combining a vacuum structure with a bottle cap in the ...
