Abstract
The utility model discloses a vacuum preservation box which is characterized in that a manual air pump capable of exhausting air inside the box to atmosphere is penetrated in a hole arranged in the box wall of a storage box, wherein an air pumping opening of the manual air pump which seals off the hole is arranged inside the storage box; an operating handle of the manual air pump is exposed out of the storage box; a door plate mounted on the opening in one side wall of the storage box is moveable relative to the opening through manual operation so as to open or close the opening; the manual air pump exhausts the air inside the storage box to absorb the door plate so as to seal the opening, so that a sealing gasket fixed on the periphery of the opening contacts and is matched with the inner side surface of the door plate due to the extrusion from the door plate so as to seal the inside of the storage box. According to the vacuum preservation box, the structure is simple, the sealing degree is high, the vacuum maintenance time and the preservation time can be prolonged, no power is consumed, low carbon and environmental protection are achieved and a large amount of food is preserved.
Description
Technical field
The utility model relates to food fresh-keeping device, particularly the vacuum safe deposit box.
Background technology
Vacuum crisper is a kind of very practical food fresh-keeping device, food can be deposited categorizedly, vacuum crisper can make the food of packing into wherein be in vacuum state and by fresh-keeping, certainly, also food can be placed in the refrigerator cold deposit fresh-keeping or the vacuum crisper of vacuum freshness retaining food be positioned in the refrigerator refrigerate.The principle of vacuum freshness retaining is: with part air extraction in the vacuum crisper, make its box body inside be relative partial vacuum state, contained amount of oxygen declines to a great extent in the box body, can play breed bacteria and the vegetative effect on the food of preventing, so, preserve food with vacuum state, can the interior food of putting of fresh-keeping within a certain period of time box body.Though with the vacuum crisper cold storing and fresh-keeping in refrigerator, the food fresh keeping that is positioned in the vacuum crisper is of great benefit to, but need reach higher fresh-keeping degree by the refrigerator of electric energy work after all, in addition, only depend on common vacuum crisper that food is carried out vacuum freshness retaining, can not satisfy the demand of the modern life, the conventional vacuum crisper fresh-keeping quantity of food less than normal, the sealing grade is low, and the degree of vacuum that is reached is also lower, degree of vacuum can reduce along with escape of air, even fresh-keeping failure phenomenon occurs.
The utility model content
The purpose of this utility model is to provide a kind of vacuum safe deposit box, and it is simple in structure, and sealing grade height prolongs time and fresh keeping time that degree of vacuum keeps, need not power consumption, the environmental protection low-carbon (LC), and fresh-keeping quantity of food is big.
The purpose of this utility model is achieved in that a kind of vacuum safe deposit box, interspersed being installed with can be with air exhaustion in its casing to the manual suction pump of atmosphere in the perforate of storage box tank wall setting, its bleeding point of manual suction pump that blocks this perforate places storage box inside, and the operation lever of manual suction pump exposes to outside the storage box; The door-plate of installing on the opening that is provided with on storage box one side box wall is by manually this opening activity relatively, so that this opening is opened or seals, manual suction pump makes door-plate absorption seal this opening air exhaustion in the storage box, and make the tightening seal washer that installs along open circumferential be subjected to the door-plate extruding and the cooperation that contacts with the inner plate surface of door-plate, with the storage box inner sealing.
The utility model vacuum freshness retaining principle is identical with the principle of conventional vacuum crisper, when the artificial manual suction pump of operation with storage box in during air extraction (air extracting pump can make the degree of vacuum in the storage box further improve manually), the door-plate that is movably arranged on the storage box opening can push contact with tightening seal washer mutually under the atmospheric effect in the external world, and then reach the purpose that improves storage box sealing grade, effectively prevent escape of air, prolong the time that degree of vacuum keeps in the storage box greatly, can make the condition of high vacuum degree in the storage box keep the longer time, therefore, fresh keeping time is also longer, and perhaps outer power supply can be worked.The utility model is simple in structure, and sealing grade height prolongs time and food fresh-keeping time that degree of vacuum keeps, need not power consumption, the environmental protection low-carbon (LC), and fresh-keeping quantity of food is big.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a sectional structure scheme drawing of the present utility model.
The specific embodiment
A kind of vacuum safe deposit box, as shown in drawings, in the perforate 11 of storage box 1 tank wall setting, intert be installed with can be with its casing in air exhaustion to the manual suction pump 2 of atmosphere, manual suction pump 2 its bleeding points 12 that block this perforate 11 place storage box 1 inside, and the operation lever 3 of manual suction pump 2 exposes to outside the storage box 1; The door-plate of installing on the opening 5 that is provided with on storage box 1 one side box walls 6 is by manually these opening 5 activities relatively, so that this opening 5 is opened or seals, manual suction pump 2 makes door-plate 6 absorption seal this opening 5 the interior air exhaustion of storage box (1), and make the tightening seal washer 4 that installs along opening 5 peripheries be subjected to door-plate 6 extruding and the cooperation that contacts with the inner plate surface of door-plate 6, with storage box 1 inner sealing.Described manual suction pump 2 is not limited to the statement category shown in these specific embodiments and the drawings, also can be the manually operated manual suction pump of other any dependence.
On the whole external box wall of storage box 1, thermal insulation layer 9 is being set, prevent to take place in atmosphere and the storage box interchange of heat, the food that places in the storage box 1 is preserved in suitable range of temperatures, further stoped outside air in storage box 1, to carry out transfer of heat, improve fresh-keeping degree.
Storage box 1 is packed in and supports on the seat board 10.
In storage box 1, installing the rack 7 that is layered arrangement, to reach the food layering, to deposit categorizedly.
Be hinged on storage box 1 tank wall in movable door-plate 6 one sides of installing on the opening 5.Installing hand draw ring 8 on door-plate 6 outer plate surface, i.e. grip handle, convenient pulling door-plate 6 makes described opening 5 uncovered, opens storage box 1.
