AI Technical Summary

Technical Problem

Existing vacuum food storage containers are designed too simply and cannot adjust the storage environment according to the characteristics of different foods, resulting in insufficient applicability.

Method used

A stackable vacuum food storage container was designed, which adopts a switching mechanism consisting of an arc-shaped fixing tube, an arc-shaped insertion tube, a connecting rod, an air outlet tube, and an air-blocking rod. The vacuum and non-vacuum states are switched by rotating the container body, and a miniature vacuum pump is used to control the vacuuming operation of multiple containers.

Benefits of technology

It enables separate storage based on food characteristics, is easy to operate, reduces production costs, is highly adaptable, and allows for arbitrary adjustment of the number of vacuum boxes as needed, making it widely applicable.

Abstract

The utility model discloses a stackable vacuum preservation box, which relates to the technical field of vacuum preservation containers and comprises a plurality of box bodies, two limiting blocks are fixedly arranged on the side wall of each box body, a box cover is arranged at the top of each box body, and a circular groove connected with the box body in an inserted mode is arranged at the bottom of each box cover. Through the arrangement of the arc-shaped fixing pipe, the arc-shaped inserting pipe, the connecting rod, the air outlet pipe, the partition plate and the air blocking rod, separated storage according to different food storage characteristics is achieved, the switching mode is simple, the number of the vacuum box bodies can be adjusted at will, switching between the vacuum state and the non-vacuum state can be achieved only by screwing, operation is easy, convenient and fast, and practicability is high. According to the vacuum box, only one micro vacuum pump is needed to control the vacuumizing work of the multiple box bodies, each box body does not need to be provided with one micro vacuum pump, the manufacturing cost is greatly reduced, the number of the vacuum box bodies can be freely switched according to requirements, and the vacuum box is high in applicability and worthy of popularization.
