Detailed description of the invention
Be further described the utility model below in conjunction with drawings and Examples, this is preferred embodiment of the present utility model.
Embodiment.
As shown in figures 1 to 6, a kind of vacuum crisper of the present utility model, comprise tank body 1, base 2 and upper cover 3, described tank body 1 is connected with described upper cover 3 by described base 2, described upper cover 3 is provided with hood-opening device 7 and first by gland 5, described hood-opening device 7 is connected with described upper cover 3 by gland 5 respectively with described first, and described base 2 is provided with air bag 4 and the first check valve 6, and described first check valve 6 is connected with described air bag 4 by gland 5 respectively with described first.This crisper uses seal ring 41 to prevent air from flowing into, and uses multiple check valve and air bag 4 to cooperatively interact and extracts air out crisper, this crisper good seal performance, swept volume is large, and fresh keeping time is long, practical, be convenient to processing, cost is lower, is suitable for large range promotion use.
