Abstract
The utility model relates to a fresh-keeping device capable of making vacuum, which comprises a sealable fresh-keeping plastic bag and a jet vacuum pump, wherein, the jet vacuum pump is a T-branch pipe, a pipe opening of one end is sheathed with a water pipe, and the an opening pipe of one end is a water outlet; a non-return valve is arranged on the connecting opening of a by-passing branch pipe and the water pipe, the opening of the by-passing branch pipe is communicated with a flexible pipe, and an injection needle is arranged on the free end of the flexible pipe. The utility model has simple structure and can be connected to a water tap without disturbing the use of water; the utility model can also be used conveniently.
Description
The utility model belongs to home-use packaging for foodstuff device, especially for the fresh-keeping device of fresh provisions.
The food fresh keeping packing that family uses is the most commonly used with plastic bag.The general practice is that the aquatic foods product are contained in sealing preservation in the food bag.Its shortcoming is always to have air to exist in the sealing bag, and air is the factor that influences food fresh keeping.
The purpose of this utility model is to propose a kind of preservation device technical scheme of making vacuum, solves the problem of making the vacuum freshness retaining condition when family uses fresh-keeping plastic bag.
Content of the present utility model comprises a sealable fresh-keeping plastic bag, also has a jet vacuum pump, the structure of jet vacuum pump is a three-way pipe, the one end mouth of pipe can with the water pipe socket, the one end mouth of pipe is a water outlet, bypass branch and water pipe handing-over mouth are non-return valves, and the bypass branch mouth is communicated with a flexible pipe, and hose free end has an injection needle.
Characteristics of the present utility model are that the negative pressure of utilizing current to form vacuumizes freshness protection package.The design's device simple in structure, practical.
Embodiment of the present utility model as shown in drawings.
Accompanying drawing is an overall schematic of the present utility model.
Number in the figure is represented respectively:
1. jet pump, 2. non-return valve, 3. vacuum lamp, 4. water halter, 5. water inlet pipe mouth, 6. effluent pipe mouth, 7. flexible pipe, 8. injection needle, 9. fresh-keeping foodstuff bag.
In conjunction with the accompanying drawings the utility model is specified:
This device is whole to comprise that the structure of jet pump 1, flexible pipe 7, injection needle 8, freshness protection package 9, jet pump 1 is a three-way pipe, comprises that coolant inlet pipe 5, the coolant outlet pipe 6 and the bypass branch that connect are vacuum lamp 3.Coolant inlet pipe 5 is enclosed within on the water halter 4, vacuum lamp 3 has non-return valve 2 with the overflow pipe junction.Vacuum lamp 3 is communicated with flexible pipe 7, syringe needle 8, and syringe needle 8 thrusts leak free freshness protection package 9.
The usage of this device is a tap water when flowing, jet pump 1 can form negative pressure with the air in the freshness protection package 9 along syringe needle 8, flexible pipe 7, vacuum lamp 3 by non-return valve 2 sucking-offs, and water can not enter.After air is taken out to the greatest extent in freshness protection package, syringe needle 8 can be transferred to, paste the non-drying glue sheet rapidly at the pin hole place, can make to keep vacuum in the freshness protection package.
This device construction is simple, can be connected at ordinary times and not hinder water on the water halter.Also very convenient during use.
