Above-mentioned mechanical drive hand lever 8 can move forward and backward in cylinder 11 with piston 12.
The above-mentioned rear side that vacuumizes case 1 is provided with outgassing nonreturn valve 6.
Above-mentioned air inlet box 3 internal fixation have gas regulation piece 4.
The beneficial effects of the utility model are:
1, the utility model adopts manual mode by one or many push-and-pull piston, can make to produce the degree of vacuum that is lower than 0.7Mpa in the storage tank, and under the indication of vacuum indicator, can select to reach the optimal vacuum pressure of oneself expecting.
2, the utility model adopts gas regulation piece 4, and the ethene that discharges in the time of can removing fruits and vegetables and deposit delays the overdone of fruits and vegetables, by using the oxygen consumption agent, can reduce oxygen concentration in the storage tank, improve gas concentration lwevel, suppress the aerobic respiration and the decomposition of food, the freshness date that further prolongs food.
3, the storage tank that uses in the utility model is food grade PP material, has outstanding durability and shock-resistant ability, and by U.S. FDA (Food and Drug Administration) checking, for stored food overall safety.And common crisper adopts the PC material, and box body wall is thin, durability, poor impact resistance.
4, the utility model is fixed with sealing member around lid 9, makes that the degree of vacuum in the storage tank 2 can maintain metastable state the long period, avoids frequent push-and-pull mechanical drive hand lever.

The specific embodiment
Embodiment 1
A kind of vacuum energy-saving fresh-keeping box, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, contain storage tank 2, be provided with in the bottom of storage tank 2 and vacuumize case 1, air inlet box 3 is installed in storage tank 2, in the bottom of air inlet box 3 outgassing nonreturn valve 5 is installed, the installed in front of storage tank 2 has lid 9, and lid button 7 is installed on the lid 9.Lid 9 is movably connected on the storage tank 2 by axle 13, also is fixed with vacuum indicator 10 on it, and seal ring 17 is installed around the lid 9.Lid button 7 is movably connected on the lid 9 by axle 14, and lid button 7 is provided with blow off valve 16 and seal ring 15.Vacuumizing case 1 is made up of mechanical drive hand lever 8, cylinder 11, piston 12; Mechanical drive hand lever 8 is installed in vacuum tank 1 front, and the one end is connected with piston 12, and the other end stretches out and vacuumizes outside the case 1: piston 12 is installed together with cylinder 11 coupling sealings.Mechanical drive hand lever 8 can move forward and backward in cylinder 11 with piston 12.The rear side that vacuumizes case 1 is provided with outgassing nonreturn valve 6.Air inlet box 3 internal fixation have gas regulation piece 4.
Principle of work: adopted outgassing nonreturn valve 5 and outgassing nonreturn valve 6, during pulling mechanical drive hand lever 8, outgassing nonreturn valve 5 conducting gas boxes 3 and cylinder 11, outgassing nonreturn valve 6 not conductings, the gas in the storage tank 2 enters in the cylinder 11.When promoting mechanical drive hand lever 8, outgassing nonreturn valve 5 not conductings keep vacuum state in the storage tank 2, outgassing nonreturn valve 6 conductings, and the gas in the cylinder 11 communicates with the external world and discharges.Vacuum pumping is carried out in circulation repeatedly, and degree of vacuum further descends in the storage tank 2, thereby uses minimum number of times push-and-pull mechanical drive hand lever 8, just can make storage tank reach desirable degree of vacuum.When drawing back lid button 7, back down blow off valve 16, make storage tank 2 internal gas pressures identical, 9 taking-ups or deposit the storage thing of being convenient to open the lid with ambient pressure.When closing lid 9, unclamped the lid button at 7 o'clock, blow off valve 16 is closed not conducting.Also because adopted the gas regulation piece, this piece can be that groundwork is sodium sulphite, sodium bicarbonate, the synthetic oxygen consumption piece of making of reducibility iron powder, also can be the regulating block of similar palladium carbon catalyst, the gas regulation piece makes storage tank when isolating with outside air, has further reduced oxygen and the concentration that comprises the gases that accelerate the ripening such as ethene, thereby the aerobic respiration of more effective inhibition food and aerobic decompose, and have reached the purpose that prolongs fresh keeping time to greatest extent.
