Vacuum refreshing system

Abstract

The invention relates to a vacuum refreshing system, comprising a tank (2) and a vacuumizing host machine (1) above the tank (2); the vacuum refreshing system is characterized in that: the tank (2) comprises a vessel (22) and a vessel cover (21) arranged at the top part of the vessel (22); a sealing ring (23) is arranged at the periphery of the vessel cover (21), a dial plate (26) is arranged in the middle part of the vessel cover (21), figures 1-31 for indication and one picking sheet (24) are arranged on the scale zone of the dial plate (26), a one-way valve (25) is arranged in the middle part of the dial plate (26), and an air bag (27) is arranged at front side or rear side of the dial plate (26). The vacuum refreshing system adopts a motor-driven vacuum pump for air exhausting, the vacuumizing speed is rapid, the negative pressure is above 50Pa, in the operation and using process, the vessel condition can be monitored in a real-time way, and whether the vessel is leaked can be judged, so as to make corresponding display or control according to different conditions.

Description

technical field [0001] The invention relates to fresh-keeping equipment, in particular to a vacuum fresh-keeping system. Background technique [0002] At present, there are many kinds of fresh-keeping boxes on the market, most of which are exhausted by pressing the lid or using a manual air pump. To detect the vacuum degree in real time during the vacuuming process, and give instructions and alarms, it is impossible to accurately judge whether the vacuum environment in the container has reached the set requirements every time it is used, which will have a great impact on the freshness of food, and The preservation effect is different every time. This will affect the judgment of the user, and in serious cases will affect the health. Contents of the invention [0003] In view of the defects existing in the prior art, the object of the present invention is to provide a vacuum preservation system, which uses an electric vacuum pump to pump air, has a fast vacuuming speed, an...
