Abstract
To enhance the fresh-keeping effect of foods, and extend the fresh-keeping time, the utility model designs especially a vacuum fresh-keeping box for holding foods wherein the design can be used conveniently and has a good fresh-keeping effect. The vacuum fresh-keeping box comprises a box body 1, a box cover 2, a joint washer 3, an air extracting valve 4, and a pressure indicator 5. The air in the box is pumped by the air extracting pump to preserve foods in the vacuum environment.
Description
Technical field
The utility model relates to a kind of container of splendid attire food, and concrete is a kind of vacuum crisper.
Background technology
The container of past splendid attire food is general bowl, dish, box.For fresh-keeping, bowl, dish, the box that will fill food are usually put refrigerator into.In the atmosphere various bacteriums are always arranged, the air quality in the refrigerator is poorer.Therefore, the poor effect of food fresh keeping, the resting period of a specified duration food spoiled easily.
Summary of the invention
In order to improve the fresh-keeping effect of food, increase the fresh-keeping resting period, the utility model is ad hoc has counted a kind of vacuum crisper of splendid attire food of easy to use, good refreshing effect.
The principle of work of vacuum crisper is seen Fig. 1, Fig. 2, and this vacuum crisper is made of box body 1, lid 2, tightening seal washer 3, evacuating valve 4, pressure indicator 5.Resilient tightening seal washer is placed in the binding site of box body and lid.Box body and lid are made by metal, enamel or hard plastic, and evacuating valve and pressure indicator all are installed on the lid.Taper valve core 6, spring 7 are arranged in the evacuating valve of this vacuum crisper, air can only be drawn out of can not reflux, the taper valve core afterbody has a long handle.Be used for manual venting.Evacuating valve is made of taper valve core 6, spring 7, valve nozzle nut 8, the valve nozzle 9 of bleeding, tightening seal washer 10, nut 11, tightening seal washer 12, the valve casing top 13 of bleeding, tightening seal washer 14, the valve casing bottom 15 of bleeding.Bleed valve casing top and the bottom organizine mouths with tightening seal washer 14 driving fits, bleed between valve casing top and lid through nut 11 by tightening seal washer 12 driving fits.Bleed valve nozzle 9 and bleed tightening seal washer 10 is arranged between valve casing top is compressed it by valve nozzle nut 8.
When in box body 1, putting into the lid 2 that tightening seal washer 3 is arranged on the food bonnet, the valve nozzle 9 of bleeding of evacuating valve 4 is connected on the extraction pipe of air extracting pump and bleeds.After pressure indicator indication air is exhausted, take out extraction pipe, close evacuating valve at the effect inferior pyramidal spool 6 of spring 7.Air is taken out the back bar pressure with box body and lid force together tightly in the box.In box, get along well air contact of food, few bacteria, fresh keeping time is long.If vacuum crisper is put in the refrigerator, fresh-keeping effect is better, just can deposit for a long time.When need open the lid, the long handle of taper valve core afterbody is pulled outwardly, in the air admission box, lid unclamps naturally.
The pressure indicator of this vacuum crisper can adopt simple and easy inexpensive pressure gauge, and an also available elastic membrane 16 is fixed a pressure indication body 18 (see figure 3)s and come qualitative display box internal pressure on the elastic membrane.Bar pressure can be seen 18 displacements of pressure indication body with the elastic membrane compressive strain by the aperture on the pressure indicator shell 17 when air is evacuated in the box.Can make an outstanding step 19 on the pressure indication body 18, it can trigger contact switch 20 and produce electric signal output when the pressure indication body is shifted.The electric signal may command minipump of output stops to bleed.Also can use small-sized hand-operated pump bowl to bleed,, be convenient to outdoor use without power supply.
Good effect of the present utility model: batch manufacturing is with low cost, and is easy to use, and the effect of food fresh keeping is splendid, and the holding time is long.
