Abstract

The utility model relates to a corrosion-proof, damp-proof and dust-proof vacuum fresh keeping box which can keep fresh for foods, vegetables, meat, fishes, aquatic products, marine products and medicines and is used for storage and transportation. A box cover is also called a vacuum utensil cover. The center of a cover plate (1) of the vacuum utensil cover shown in the picture 1 is provided with cylindrical barrel, a vacuum utensil mouth head (4) is arranged in the cylindrical barrel, and the external thread of the vacuum utensil mouth head and internal thread of a rotary hand wheel (5) can act mutually; a mouth head positioning sleeve (3) is fixed on the inner wall of the cylindrical barrel of the cover plate (1) by a memory alloy shaft (2). When the rotary hand wheel (5) is rotated, the vacuum utensil mouth head (4) can move along the axial direction in the mouth head positioning sleeve (3), and thus, the utility model can realize to open and close air holes on the cover plate (1). The utility model is applied to families, hotels, trains, ships and hospitals, and besides, the utility model provides storage and transport package for operators.

Description

Vacuum fresh-keeping box

The utility model relates to the fresh-keeping, anticorrosion, moistureproof, dustproof of food, vegetables, meat, fish, aquatic products, marine product and medicine etc., particularly the preservation of food of people's daily life etc., the vacuum fresh-keeping box of transportation.

What fresh-keeping, anticorrosion, moistureproof, the dustproof people of food were used always is electric refrigerator, and find several problems in the process of using electric refrigerator: 1, food is dry easily, deposits several different food and scurries flavor easily; 2, consumption of current is big, and power consumption every day is about 1 degree; 3, the amount of food of depositing is limited; 4, inconvenience transportation; 5, vacuumize Keeping life weak point etc. relatively.More to vacuumizing store method at present, use small-sized hand-operated vacuum pumping pump as canned food, plastics for the vessel that vacuumize packing, family's use, its sealing makes and seals with adhesive tape, and existing problems are troubles of operation.In addition, make the used life that seals with adhesive tape short, only be useful for the small-sized vessel of family.

The purpose of this utility model provides a kind of newly-designed vacuum fresh-keeping box, and it mainly solves the vacuum ware lid when vacuumizing.

The purpose of this utility model is achieved in that the center on case lid opens a circular hole, vacuumizes on this circular hole, after exhausting round mouth is sealed, and the way of the employing tape seal that has, this way is short service life, is not easy to adopt electric vacuum pump again.The utility model is to adopt vacuum ware mouth on circular hole, and the negative thread of vacuum ware mouth and the aspirate tube of vacuum pump have externally threaded tube head and join; The outside thread of vacuum ware mouth and the negative thread mutual action of rotation hand wheel make vacuum ware mouth along moving axially, and realize that the air gate way of open and close cover plate realizes.

The concrete structure of utility model has following enforcement and accompanying drawing thereof to provide:

Fig. 1 is according to the total section-drawing that the utility model proposes vacuum extractor.

Describe structure and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

The utility model is by casing, and vacuum rubber seal ring, case lid claim vacuum ware lid again.A cylinder barrel is opened in the center of the cover plate (1) of vacuum ware lid, and vacuum ware mouth (4) is housed in the cylinder barrel, and the negative thread of vacuum ware mouth (4) and the aspirate tube of vacuum pump have externally threaded tube head and join; The outside thread of vacuum ware mouth (4) contacts with the negative thread of rotation hand wheel (5), rotates rotation hand wheel (5), make vacuum ware mouth (4) mouth locating bush (3) in along moving axially the pore on the realization open and close cover plates (1).Mouth locating bush (3), in the cylinder barrel of cover plate (1), pass through memorial alloy axle (2), diameter is 2 millimeters, be heated contraction and be placed in the mouth locating bush (3), again with rotation hand wheel (5), vacuum ware mouth (4), mouth locating bush (3) assembling one, put in the cylinder barrel of cover plate (1), the memorial alloy axle (2) after the assembling cools off elongation at ambient temperature, mouth locating bush (3) is fixed on the cylinder barrel inwall of cover plate (1).Action principle according to bolt and nut, rotation hand wheel (5) makes vacuum ware mouth (4), in mouth locating bush (3) along moving axially the gas port of opening cover plate (1), when air is found time in the casing, rotation hand wheel (5) vacuum ware mouth (4) covers the gas port of tight cover plate (1), and the tube head with aspirate tube takes down at last.

The utility model is used family, restaurant, train, steamer, hospital.The package of preservation, transportation also is provided for the manager.So the utility model is widely used and is remote.
