Product Details knob ringed groove
silicone handle
vacuum valve
The handle of drawer plays an important role in this vacuum device. The metal part up front is a support while pulling out to reach pressure balance; the middle part is a soft and flexible silicone handle whose contact surface with front cap of the inner box must be flat, or the vacuum device won’t work. The bottom part is a knob which users can remove while the crisper needs washing.

sheetmetal elevated platform
vent
The hole which can be covered by the handle acts as a vent while the drawer is being vacuumed, and as a intake while releasing vacuum. The ringed groove surrounding the handle fits the mouth of vacuum machine, making it perfectly sealed while pumping. Behind the hole is a slightly elevated platform that prevents the knob blocking the intake while releasing vacuum.

vacuum machine
To be connected with the food management application, there are colour detector and white LED assembled in the mouth of vacuum machine. While pumping, the colour detector detects the colour of the handle and sends it to the application by bluetooth, so the interface will show up information of the corresponding crisper.
