Benefits of technology

The present invention provides a vacuum storage box that allows consumers to use an air pump to vacuumize the box. This improves the efficiency of the air pump and satisfies the consumer demand for long-term item storage. The box has a vacuum pumping component that can be fixed on the box body or used for long-term item storage. By detachably connecting the vacuum pumping component with the box body, the vacuum state of the inner cavity of the box body can be maintained. This allows for efficient use of the vacuum pumping component and satisfies the consumer demand for long-term item storage.

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.

embodiment 1

[0021]The present invention relates to a vacuum storage box, which, as illustrated in FIGS. 1 and 2, comprises a box body and a vacuum pumping component 3 capable of being fixed on the box body. The box body includes a body 1 and a cover 2; an outer wall is provided with an accommodating groove 21; the vacuum pumping component 3 can be fixed in the accommodating groove 21; a vacuum pumping channel is disposed at the bottom of the accommodating groove 21; an exhaust nozzle matched with the vacuum pumping channel is disposed on a bottom surface of the vacuum pumping component 3; and the vacuum pumping component 3 is provided with a pressure detector which is configured to detect the air pressure of the inner cavity of the box body via the vacuum pumping channel. When the vacuum pumping component 3 is connected to the vacuum pumping channel, if the air pressure of the inner cavity of the box body is greater than the threshold, the vacuum pumping component 3 will pump gas in the inner c...

embodiment 2

[0025]In a preferred embodiment 2 of the vacuum storage box provided by the present invention, the main technical proposal of the embodiment is the same with that of the embodiment 1. Features not explained in the embodiment adopt the explanation in the embodiment 1, so no further description will be given here. The difference between the embodiment and the embodiment 1 is that the box body is provided with a pressure detector. When the vacuum pumping component 3 is connected to the vacuum pumping channel, the pressure detector is electrically connected with the vacuum pumping component 3 and configured to trigger the vacuum pumping component 3 when the air pressure of the inner cavity of the box body is greater than the threshold. Considering the overall cost of products and other reasons, the conventional pressure detector will generally not adopt a small-size and high-precision pressure sensor for detection but adopt a spring or a spring plate for detection. Under the condition, ...

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...
