Abstract
The utility model relates to a domestic vacuum food fresh-keeping device which belongs to the technical field of human necessities. The vacuum food fresh keeping device is composed of a tap, a jet injector, a water prevention and regurgitation device, a vacuum valve, flanged joint and a vacuum container, wherein, the jet injector is connected with the tap; the water prevention and regurgitation device and the vacuum valve are installed between the jet injector and the vacuum container. When the tap water is started up, the air in the vacuum container is pumped because of the function of the jet injector, and the multi-purpose fresh-keeping box has the function of food preservation in the vacuum container. The domestic vacuum food fresh-keeping device uses the tap water as the motive power, and has the advantages of no pollution, maintenance free and low cost.
Description
The utility model relates to a kind of home-use vacuum food preservation device, belongs to technical field of living necessaries of humans.
At present, existing a kind of food preservation unit on the market is that Japan utilizes the patented technology of West Germany to produce, and mainly is made of a desk fan type vacuum pump and food-packaging bag capper.The minimum pressure of pump can be extracted into about 740 torrs, and barometric pressure is about 760 torrs, promptly can take out in the atmosphere 2.6% gas, and the food in the food bag generally can be preserved 3～5 days.The shortcoming of this preservation device is: the energy is made in (1) electricity consumption, and (2) rotation speed of the fan is higher, and the maintenance problem is many, influences service life, and (3) are taken out gas flow and had only 2.6%, influence field of application, (4) package unit fetch long price, and influence is applied.
The purpose of this utility model is a kind of energy that do not need of design, and is easy to use, low-cost home-use vacuum food preservation device.
To be home-use vacuum food preservation device flow device and vacuum vessel is formed by water cock, jet pump, vacuum valve, waterproof are counter to content of the present utility model.Jet pump is connected with water cock, and waterproof is counter to flow device and vacuum valve is installed between jet pump and the vacuum vessel.When opening tap water,, play effect to the food fresh keeping in the vacuum vessel because the air in the vacuum vessel is taken out in the effect of jet pump.
Description of drawings:
Fig. 1 is the utility model structure principle chart.
Fig. 2 is an embodiment of the present utility model.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.Among Fig. 1, the 1st, water cock, the 2nd, the anti-device that flows of waterproof, the 3rd, vacuum adapter, the 4th, vacuum valve, the 5th, vaccum seal ring, the 6th, vacuum-tight container, the 7th, jet pump, the 8th, vacuum adapter.When turning on water cock 1, jet pump 7 is just taken the air of vacuum-tight container 6 away, and general home-use tap water can be extracted into the gas pressure intensity in 1 liter of container below 30 torrs in 1 minute, promptly can take out the gas more than 95%.Without tap water the time, close vacuum valve 4, just can keep the degree of vacuum in the vacuum vessel 5.The anti-degree of vacuum that flows device 2 protection vacuum vessels 5 of waterproof.Vaccum seal ring 4 is in order to keep the degree of vacuum of container.Among Fig. 2, the 9th, flange connects, and the 10th, vacuum interface to be got.When whenever using tap water, the degree of vacuum of vacuum vessel 6 just can improve constantly with standby.When vacuum sealing tableware need extract vacuum, wait to get on the vacuum interface 10 as long as be connected to the vacuum rubber pipe, open vacuum valve, the air in the tableware just can be taken away, plays the effect to the food fresh keeping in the tableware.
Claims (2)
1, a kind of home-use vacuum food preservation device is characterized in that described device is made up of water cock, jet pump, anti-device, vacuum valve and the vacuum vessel of flowing of waterproof; Described jet pump and water cock join; Described waterproof is counter to flow device and vacuum valve and is installed on the pipeline that jet pump and vacuum vessel join.
