Abstract

The utility model relates to a toy bricks type vacuum fresh-keeping box which relates to the vacuum fresh-keeping device of foods, composed of a fresh-keeping box part and a separable air pumping device, wherein, the fresh-keeping box is composed of a box body, a box cover, a sealing gasket, a one-way valve, a plug and a handle; the separable air pumping device is composed of an air pumping canister body, an air pumping canister cover, a top cover, a base, a sealing ring, a gas nozzle, a gas nozzle seat and a one-way valve; the fresh-keeping box is connected with the separable air pumping device by a flexible pipe. The required vacuum degree in the box can be achieved by repeated air pumping and air exhausting, and as a result the microorganisms on the foods bears repression or dies of asphyxia, achieving the fresh-keeping aim of putrescence prevention and mildew prevention. The toy bricks type vacuum fresh-keeping box has the advantages of reasonable structure, cheap price, strong practicability and repeatable use, and can be widely used for keeping food fresh for the household or the outgoing person.

Description

Blocks type vacuum fresh keeping box

The utility model relates to the food vacuum preservation device.

Plastic film bag in the existing food vacuum preservation technique, because of packing appearance spine and band juice food are arranged, be restricted in the use, thus, invented a kind of application number and be 89216692 vacuum fresh-keeping pot, though it has overcome above-mentioned shortcoming and has enlarged range of use, but must go back defectiveness unexpectedly, as: 1. body complexity, manufacture difficulty is big, and practicality is relatively poor; 2. the laborsaving principle of performance of a different dive of bleeding, inconvenience to some extent in the use; 3. can't learn level of vacuum.

The purpose of this utility model be to overcome above-mentioned defective and provide a kind of manufacturing simple, practical, bleed laborsaving, can learn the cordwood system vacuum crisper of degree of vacuum, also kept simultaneously the sort of not only reusable but also portable advantage of prior art, for the family and the government functionary that goes out provide very easy antistaling vacuum container.

The principle of design of cordwood system vacuum crisper is that the germ that is in the food surface under the vacuum state is suppressed or death by suffocation, thereby reaches anticorrosion, fungi-proof fresh-keeping purpose.

Its embodiment is the improvement of vacuum fresh-keeping pot: be made up of the separable air extractor of crisper partial sum.

The box body of crisper can be that end box or end box add that at least one has the middleboxes of 1-3 radial equipartition pore, forms block construction, and packing seal all is equipped with in lid and middleboxes, middleboxes and the mutual socket connection of end box on its faying face.Lid can be made dome or flat-top, and the flat-top lid of different-diameter can be used on various bottles, the jar.Chock plug, handle are arranged on the lid, and its recess has the pore and the check valve of 2-6 radial equipartition, and the shape of check valve can be cap shape or plate shaped diaphragm.

Air extractor is made up of air cylinder, air cylinder cover, top cover, base, piston, valve, valve seat etc., the valve that has an aperture is connected with pore on being arranged on air cylinder cover by flexible tube, the valve seat is plugged on the lid recess, and the pore and the diaphragm type check valve of 2～6 radial equipartitions also arranged on its midfeather.Left end is equipped with narrow meshed lid, degree of vacuum promptly thus aperture learn, when feel has gas, the expression degree of vacuum poor, also need continue to bleed, feel does not have gas, represents that promptly degree of vacuum is good.

The utility model is compared with original technology, rational in infrastructure, make simple, practical, the piston pressing action is to bleed, on to carry be exhaust, meet the labour-saving natural law, easy to use, can learn degree of vacuum by feel simultaneously, crisper is reusable, be applicable to family or travel outdoors, the government functionary is to the antistaling storing of any food.

Accompanying drawing provides structural representation of the present utility model.

Embodiment:

The cordwood system vacuum crisper is made up of the separable air extractor of crisper partial sum.Crisper is that 160 millimeters of φ, wall thickness are that 3 millimeters the end box (23) that has supporting (21), two middleboxes (20), dome lid (1) and handle (2) formed by external diameter.Middleboxes (20) have 3 radial equipartitions, diameter is the pore (22) of 4 millimeters of φ.Chock plug (9), handle (2) are arranged on the lid (1), recess have 6 communicate with middleboxes (20), the pore (16) of radial equipartition, be set with thick 0.6 millimeter cap shape diaphragm type one-way valve (8) on the flange, guarantee to open and close freely.Lid (1) and middleboxes (20), middleboxes (20) and end box (23), packing seal (19) all is equipped with in socket connection mutually on the faying face.

Air extractor has air cylinder (15), air cylinder cover (13), top cover (12), base (18), piston (11), valve (7), valve seat (6), air cylinder cover (13), base (18) is press-fitted with air cylinder (15), on the faying face that piston (11) slides seal ring (14) is housed, (17), seal ring is a consumable accessory, improve resistance to abrasion in order to reduce friction, adopt special process to vulcanize the fluorine plastic film of 0.1 millimeter of a bed thickness on the sealing surface of seal ring, for example seal ring (14) should vulcanize fluoroplastic at inside face, and seal ring (17) should vulcanize fluoroplastic at outside face.Base (18) is made and is hugged at the bottom of the maltese cross shape, and the air of piston (11) when pressing down discharged thus.Valve (7) is connected with air cylinder cover (13) by flexible tube (10), the valve seat (6) of pegging graft with valve (7) is plugged on lid (1) recess again and seal ring is housed, its midfeather also has 6 pores (5) and cap shape diaphragm type one-way valve (4) is housed, and left end is equipped with narrow meshed lid (3).

The part in addition that the utility model is relevant with food is a material with edible or medical non-toxic plastic all, check valve (4), (8) are made by nontoxic rubber with packing seal, be made of metal as a small amount of part in addition such as piston (11) (comprising piston rod), air cylinder (15), all the other are made by the common engineering plastics.

The principle of work of cordwood system vacuum crisper is when hand piston (11), air cylinder (15) inner chamber forms the region of no pressure, because the equilibrium relation of difference of pressure makes the air in the crisper back down check valve (8), air enters air cylinder (15) through each road pore, check valve this moment (4) is close to valve seat (6) midfeather under external atmosphere pressure, air is by isolated.When drawing on the piston (11), air cylinder (15) inner chamber air backs down check valve (4) through the pore discharge through flexible tube (10) and each road pore, and check valve this moment (8) is closed.Pump drainage gas so repeatedly, make the degree of vacuum that reaches required in the box, exhaust situation by feel lid (3) aperture place can be learnt the degree of vacuum that box is interior, raising along with degree of vacuum in the box, under bar pressure, check valve (8) further makes box sealed, and can shed air extractor this moment, does not tightly plug and can break away from because of the bar pressure relation makes lid (1) and box body.

(1) the preceding chock plug (9) that takes off earlier that opens the lid enters in the box outside air, eliminates can open the lid behind the inside and outside difference of pressure of box (1) and takes out food.
