But the purpose of this utility model provides a kind of long-period freshness preserving food and the edible antistaling container that need not thaw before.
Technical solution of the present utility model is: a kind of antistaling container, form by the housing 2 that has door 1, in housing 2, be provided with vacuum pump 3, be connected to conduit 4 with straight empty pump 3, be connected to check (non-return) valve 5 on conduit 4, be connected to pressure relay 6 with conduit 4, the electric contact of pressure relay 6 connects vacuum pump 3, the edge of door 1 is provided with sealing band 7, and door 1 is provided with valve switch handle 8.
Be connected to compression indicator 9 with vacuum pump 3, in housing 2, be provided with dividing plate 10,
Be connected to silencer 11 with vacuum pump 3.
The utility model is compared with prior art, can realize long-period freshness preserving to food or medicine etc., and it is not because freezing, not influence of quality to food or medicine etc., before edible, need not thaw, give very big convenience, and because objectionable impuritiess such as not fluorine-containing Lyons, ozone, foul air not can be widely used in national defence, medical treatment, family etc.
Fig. 1 is the scheme drawing of the utility model embodiment.
Below in conjunction with drawings and Examples the utility model is further described:
As shown in the figure, housing 2 and door 1 all adopt the aluminum alloy manufacturing to form, and are provided with three layers of dividing plate 10 in housing 2, and door 1 is provided with the handle 8 of by-pass valve control switch, on door 1 edge, be connected to sealing band 7, between bottom dividing plate and bottom, place vacuum pump 3, connect a conduit 4, be connected to check (non-return) valve 5 on the conduit 4 with vacuum pump 3, be connected to compression indicator 9 and pressure relay 6 with check (non-return) valve 5, the electric contact of pressure relay 6 connects vacuum pump 3, in order to abate the noise, also is connected to silencer 11 with vacuum pump 5.
Using method: and close door 1, connect the power supply of vacuum pump 3, vacuum pump 3 work, when pressure arrived certain value, pressure relay 6 control vacuum pumps 3 quit work, and when changing as pressure, pressure relay 6 makes vacuum pump carry out work again.If will open door 1, hold handle 8 and press valve switch, make internal and external pressure balance, open door 1 then.
