Abstract
The utility model discloses a fresh-keeping storage box, which comprises a box body (1), a box cover (2), a box cover negative pressure cavity (3), a box body negative pressure cavity (4), a evacuating device (5), a discharge/charge valve (7), a discharge/charge hole (8) and an evacuating hole (9). The fresh-keeping storage box is characterized in that the box body negative pressure cavity (4) and the box cover negative pressure cavity (3) are respectively arranged in the box body (1) and the box cover (2); the discharge/charge hole (8) is formed at proper position of the box cover (2); the upper part of the discharge/charge hole (8) is connected with the discharge/charge valve (7); and one side of the discharge/charge valve (7) is connected with the evacuating device (5) through the evacuating hole (9). When in use, ice cubes and foods can be arranged in the box, and the box body is evacuated by the evacuating device (5) and is filled with nitrogen through the discharge/charge valve (7) to achieve freezing, vacuum and nitrogen preservation. Anyone of the above three methods can be selected for preserving foods according to the conditions at the given time and place. The fresh-keeping storage box suits mobile and immobile food preservation occasions.
Description
Technical field
The utility model relates to a kind of utensil of preserved food, and more particularly, the utility model relates to a kind of fresh-keeping wanigan.
Background technology
At present, the method for preserving of food long period mainly is divided into methods such as freezing, vacuum, high pressure, sterilization, medicine and nitrogen preservation.Wherein, freezing method the most commonly.But freezing method relies on power supply mostly, generally speaking, must possess refrigerator, refrigerator-freezer, flows to use to be inconvenient to transport and carry; Vacuum preservation then more is used for the food preservation that plastic sheeting is made packing material, nearly all is disposable, as no specialized equipment, and the food of user in can only disposable enjoyment packing material, food toos many or too much for use, and can only abandon.Up to the present, do not see the fresh-keeping wanigan easy to carry that freezing, the vacuum of collection, nitrogen method for preserving etc. are incorporated into one on the market as yet.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, by certain improvement design, methods such as freezing, vacuum, nitrogen preservation is integrated in one, and makes fresh-keeping wanigan both have fresh-keeping storage thing function, is convenient for carrying again.
The purpose of this utility model is achieved by following technical proposals.
Establish casing negative pressure cavity 4 and case lid negative pressure cavity 3 respectively in casing 1 and case lid 2, case lid 2 appropriate locations are provided with exhaust air-filled pore 8, and exhaust air-filled pore 8 tops connect exhaust charge valve 7, and the one side connects air extractor 5 by aspirating hole 9; Air extractor 5 is provided with one group of device of the movable part 14 of bleeding of band seal ring 6 for the end that the slideway 13 of bleeding connects with aspirating hole 9 is provided with extraction valve 11 and spring 12 in the slideway 13 of bleeding; Seal by seal gasket 10 between casing 1 and the case lid 2.
Principle of the present utility model is: owing to casing, case lid are provided with negative pressure cavity, formed vacuum heat-insulating layer, reduced the transmission of heat energy significantly, when inserting in the case, can keep the low-temperature condition in the case long period, simultaneously to ice cube, be provided with exhaust charge valve and exhaust air-filled pore on the case lid, can charge into nitrogen or other anti-corrosive properties gas in case, exhaust air-filled pore one side is provided with air extractor, can bleed to make in the case by air extractor to form vacuum and air is extracted.
The beneficial effects of the utility model are: 1, freezing, vacuum, the nitrogen method for preserving trinity can make the food in the wanigan reach fresh-keeping purpose the long period.2,, reach and make things convenient for practical purpose owing to do not use uses of can flowing of external power supply, this fresh-keeping wanigan.3, when not possessing above-mentioned three kinds of conditions simultaneously, can take any one method for preserving according to the condition of there and then, make this fresh-keeping wanigan possess the function of fresh-keeping storage thing simultaneously, overcome that fresh-keeping on the market wanigan at present is subjected to condition restriction and the problem that can not conveniently use.
Description of drawings
Fig. 1 is a sectional structure scheme drawing of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
The casing 1 of machine-shaping band casing negative pressure cavity 4; The case lid 2 of machine-shaping band case lid negative pressure cavity 3, exhaust air-filled pore 8, aspirating hole 9 and the slideway 13 of bleeding is assembled then.During assembling, casing 1 and being connected of case lid 2 can be adopted turnover plate type and sliding cover type, and its junction seals with seal gasket 10; Exhaust air-filled pore 8 top movable sealed attachment exhaust charge valves 7, the aspirating hole 9 of one side connects extraction valve 11 with slideway 13 bonded assemblys of bleeding are inboard, and the spring 12 of packing in the slideway 13 of bleeding, is with the movable part 14 of bleeding of seal ring 6.
During use, if there and then has ice cube, nitrogen, the food that can in case, put into ice cube and need to preserve, and extract air in the case by air extractor 5, charge into nitrogen by exhaust charge valve 7 then, can to need preserve article form freezing, vacuum, the Trinitarian fresh-keeping and storing effect of nitrogen method for preserving.There and then can be put into food as there not being ice cube in case, extract air in the case by air extractor 5 then, and charge into nitrogen by exhaust charge valve 7, forms the effect of nitrogen vacuum preservation.If there and then does not have nitrogen, can in case, put into ice cube and food, extract air in the case by air extractor 5 then, form freezingly, the effect of vacuum preservation is not if there and then has ice cube and nitrogen, can extract air in the case by air extractor 5, form the effect of vacuum preservation.
Claims (1)
1, a kind of fresh-keeping wanigan, comprise casing (1), case lid (2), case lid negative pressure cavity (3), casing negative pressure cavity (4), air extractor (5), exhaust charge valve (7), exhaust air-filled pore (8), aspirating hole (9) is characterized in that, in casing (1) and case lid (2), establish casing negative pressure cavity (4) and case lid negative pressure cavity (3) respectively, case lid (2) appropriate location is provided with exhaust air-filled pore (8), and exhaust appendix (8) top connects exhaust charge valve (7), and the one side connects air extractor (5) by aspirating hole (9).
