Description
Technical field
The utility model relates to a kind of for content provides the package of special vacuum environment, relates in particular to by the accessory equipment of bleeding this compressed bag is vacuumized vacuum compression bag with article in compression and the storage bag.
Background technology
Vacuum compression bag is mainly by coming the volume of article in the compressed bag with the mode of air extraction in the bag, thereby is convenient to preserve article, and the article in the vacuum compression bag are difficult for producing and go mouldy simultaneously, and the holding time is long.Therefore, except the manufactured materials of vacuum bag own, the leak tightness of the exhaust gear on the bag is to guarantee that article can keep the key of compressive state for a long time.
The exhaust gear sealing effectiveness of at present known vacuum compression bag product is not good, is unfavorable for being sealed in the long-time preservation of the article in the bag like this.In addition, the structure of the exhaust gear of known product is multipart combination, relative complex, and the commercial production cost is excessive.For example, at publication number is " CN101157417 ", name is called in the Chinese invention patent of " a kind of vacuum compression bag gas nozzle that improves structure " and discloses a kind of vacuum compression bag gas nozzle that improves structure, comprise pedestal, seal ring and end cap, pedestal has air intake and air extractor duct, there are seal ring and end cap in the air extractor duct place of pedestal spiral respectively, it is characterized in that: described pedestal is made up of interior cover and overcoat, interior cover has the exhaust passage, the exhaust passage air inlet end of interior cover extends jacket bottom and constitutes the air intake of pedestal, the air extractor duct of pedestal is located at the overcoat top open part, the exhaust passage inwall is provided with flow deflector, flow deflector extends the exhaust passage air inlet end, also be fixed with an annulus in the described exhaust passage, the outlet side, exhaust passage of interior cover is provided with a piston pad, and piston pad is provided with the slotting axle of band dop, insert dop on the axle and pass annulus and holding, cover top and seal outlet side, described exhaust passage in piston pad places in the annulus outside.The invention has the beneficial effects as follows that such sealing structure is good, and gas has sufficient space to flow when bleeding, it is satisfactory for result to bleed.In addition, be " CN1785160 " at publication number, name is called in the Chinese invention patent of " a kind of vacuum bag of efficiently bleeding " and discloses a kind of vacuum bag of efficiently bleeding, include bag, bag is provided with the mouth of bleeding, and is provided with one deck dividing plate in the mouth of bleeding, and has air gate on this dividing plate; The obstruction sheet that can be used to block air gate is installed on described dividing plate.When vacuumizing, pump bowl docks and outwards stirs the piston of bleeding with the mouth of bleeding, block sheet and in bag, produce deformation under the positive air pressure effect, so the air in the bag is through air gate, the mouth and block of bleeding is drawn out of after slit between the sheet enters in the pump bowl, when then piston being pushed away preparation in pump bowl and bleeding next time, thereby block under the pressurized air effect in the mouth of bleeding sheet reset clog air gate in case in the mouth of bleeding residual air reenter in the true airbag, like this with less number of times, in the short period of time vacuum bag can more thoroughly be evacuated, so pumping efficiency height of the present invention, vacuumize effective; Its mouth of bleeding that brings simple in structure is young simultaneously, bleeds easily.
Though above-mentioned prior art has illustrated valve or vacuum compression bag and the exhaust valve thereof that is used to vacuumize, but because the complex structure of these valves, vacuumize the back owing to mainly concentrated its underpart, the stressed position of inner patch causes unbalance stress, thereby easy deformation and cause the gas leakage of whole vacuum compression bag, and it is complicated that these gas nozzle structures are slightly disliked, and increased the industrial implementation cost simultaneously.
