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.

What is claimed is: 
     
         1 . A vacuum storage box, comprising at least one box body and a vacuum pumping component capable of being fixed on the box body, wherein the box body is provided with a vacuum pumping channel; the vacuum pumping component is detachably connected to 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, 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; and 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. 
     
     
         2 . The vacuum storage box according to  claim 1 , wherein an outer wall of the box body is provided with an accommodating groove; and the vacuum pumping component can be fixed into the accommodating groove. 
     
     
         3 . The vacuum storage box according to  claim 2 , wherein the vacuum pumping channel is disposed at the bottom of the accommodating groove; and an exhaust nozzle matched with the vacuum pumping channel is disposed on a bottom surface of the vacuum pumping component. 
     
     
         4 . The vacuum storage box according to  claim 2 , wherein the box body includes a body and a cover; and the accommodating groove is disposed on the cover. 
     
     
         5 . The vacuum storage box according to  claim 1 , wherein the vacuum pumping component 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. 
     
     
         6 . The vacuum storage box according to  claim 5 , wherein the box body is provided with a pressure detector; and when the vacuum pumping component is connected to the vacuum pumping channel, the pressure detector is electrically connected with the vacuum pumping component and configured to trigger the vacuum pumping component when the air pressure of the inner cavity of the box body is greater than the threshold. 
     
     
         7 . The vacuum storage box according to  claim 1 , wherein the vacuum pumping channel is provided with a through hole for running through the box body; and a one-way valve is disposed in the through hole and turned on during the vacuum pumping of the vacuum pumping component. 
     
     
         8 . The vacuum storage box according to  claim 7 , wherein a pressure relief rod is also disposed in the through hole; and an intake passage is formed by the through hole when the pressure relief rod is tilted and oscillated.
