Vacuum storage box

Abstract

The present invention provides a storage box, which comprises a box body and a vacuum pumping component capable of being fixed on the box body. The box body is provided with a vacuum pumping channel. The vacuum pumping component is detachably connected with the vacuum pumping channel. When the vacuum pumping component is connected to the vacuum pumping channel, if the air pressure of an inner cavity of the box body is greater than the threshold, gas in the inner cavity of the box body will be pumped to allow the inner cavity of the box body to maintain the vacuum state. During the daily use of consumers, a plurality of box bodies and a vacuum pumping component may be prepared. When store items of a specific box body need to be stored for a long time, the vacuum pumping component is fixed on the box body.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the technical field of storage boxes, in particular to a vacuum storage box.BACKGROUND OF THE INVENTION[0002]In order to store food and other perishable items, more and more storage containers adopt vacuuming means to prolong the oxidative deterioration process of items so as to achieve the objective of freshness.[0003]Currently, there are mainly two means for the vacuum pumping of the storage containers. One is as follows: a vacuum unit and a container are separated; in the use process, an air pump leans against a vacuum valve on the container for vacuum pumping; and after the vacuum pumping process is completed, the air pump is separated from the vacuum valve. The means adopts one air pump for the vacuum pumping of a plurality of containers, so that the cost is low. But three are also some defects: (1) as daily-use vacuum vessels are not highly precise vessels and have limited sealing performance, the degree of vacuum wi...

Benefits of technology

[0016]The advantages of the present invention: the present invention provides a storage box, which comprises a box body and a vacuum pumping component capable of being fixed on the box body. The box body is provided with a vacuum pumping channel. The vacuum pumping component is detachably connected with the vacuum pumping channel. When the vacuum pumping component is connected to the vacuum pumping channel, if the air pressure of an inner cavity of the box body is greater than the threshold, gas in the inner cavity of the box body will be pumped to allow the inner cavity of the box body to maintain the vacuum state. When the vacuum pumping component is separated from the vacuum pumping channel, the connection between the inner cavity of the box body and the outside is hindered by the vacuum pumping channel to allow the inner cavity of the box body to maintain the vacuum state. During the daily use of consumers, a plurality of box bodies and a vacuum pumping component may be prepared. When store items of a specific box body need to be stored for a long time, the vacuum pumping component is fixed on the box body. Thus, when the air pressure of the inner cavity of the box body is greater than the threshold, the vacuum pumping component will pump gas in the inner cavity of the box body to allow the inner cavity of the box body to maintain the vacuum state. When store items of a specific box body need to be stored for a short time, the vacuum pumping component is taken from the box body for long-term item storage and used for the vacuum pumping of the inner cavity of the box body after the items are placed well and may be continuously placed on the box body for long-term item storage after the vacuum pumping process is completed. Therefore, the vacuum pumping component can be more fully utilized and the consumer demand for long-term item storage can be also satisfied.

Problems solved by technology

But three are also some defects: (1) as daily-use vacuum vessels are not highly precise vessels and have limited sealing performance, the degree of vacuum will be inevitably gradually reduced in the storage process, and long-term storage cannot be achieved unless the vessels are regularly vacuumized by consumers; and (2) as the air pump is separated from the vessel and only needs to be used in the vacuum pumping process, the air pump tends to be randomly placed after use and hence is lost and is not conducive for later use.

Although the means can prolong the preservation time, an air pump is fixed on a box body and can only vacuumize the box body matched therewith, so that the utilization rate of the air pump is very low.

Moreover, the air pump is a relatively expensive device, so the replacement of beneficial storage containers by similar vessels is unrealistic and wasteful as for consumers.
