It is provided with plastic cement valve rod, is provided on the pumping chamber by pressure cylinder.
It is described that the folding that several places are connected is provided with by pressure cylinder in novel air extraction structure on above-mentioned crisper
Portion.
It is described that the upper surface of pressure cylinder is provided with handle in novel air extraction structure on above-mentioned crisper.
It is described to be tied by pressure cylinder for food-grade flexible material is manufactured in novel air extraction structure on above-mentioned crisper
Structure.
It is described to be respectively provided with by the pressure cylinder and bottom of pumping chamber in novel air extraction structure on above-mentioned crisper
There is spring fixed seat, is provided with spring between described two spring fixed seats.
In novel air extraction structure on above-mentioned crisper, it is provided with a return-air hole on the fresh-keeping box cover, described time
Return-air lid is provided on stomata.
In novel air extraction structure on above-mentioned crisper, the return-air lid is knot made of food-grade flexible material
Structure.
In novel air extraction structure on above-mentioned crisper, the return-air lid has chamber, the middle-end of the return-air lid
Portion forms the fixation annular groove for being arranged on return-air hole, and the upper end of the return-air lid is according to the pressure change in crisper
And it is raised or sunken.
Compared with the prior art, the utility model has prominent and beneficial technical effects that:
1. the air inside crisper is taken away, is allowed by being provided with an air extractor on box cover by the utility model
Food in crisper extends its storage time, so that food is unlikely to deteriorate.
2. the utility model is by pressing the air extracted in crisper by pressure cylinder, when will be by pressure cylinder pull-up, pumping
Channel is opened, and outlet passageway is closed by plastic cement valve rod, and the air in crisper is extracted at this time, when being pressed downward by pressure cylinder, out
Gas channel is opened, and air discharge, bleed-off passage is closed by plastic cement valve rod.
3. the spring of the utility model design is to can press by the elastic force of spring after pressing is by pressure cylinder
Cylinder resets, and reduces certain labour, saves strength.
4. the utility model is provided with a return-air lid on box cover, can be covered by return-air end can learn it is fresh-keeping
The number of box inner air, when return-air covers end to lower recess, illustrate the air inside crisper it is less, when return-air covers end
Portion's explanation is still upward, and it is insufficient to illustrate that the air inside crisper extracts.
