Abstract
The utility model discloses a vacuum sealing nozzle, belonging to the sealing device, which comprises a sealing body. An air hole is arranged in the sealing body; a pressing block is arranged out of the sealing body; the tope of the sealing body is provided with a top cover. The utility model is characterized in that a cone valve is arranged in the air hole; the conical surface of the cone valve is matched with the inner conical surface of the sealing body; a blocking sleeve is arranged on a sealing body at the back side of the cone valve. The utility model is suitable for any soft packaging bags. After the packaging bag is pumped in vacuum, the cone valve can automatically prop closely and seal the air hole under the effect of the positive and negative pressure difference. The utility model has the advantages of convenient use, good sealing performance, low cost and repeat utilization, which is particularly suitable for family use.
Description
Technical field
The utility model provides a kind of vacuum seal to shut up, and belongs to seal arrangement.
Background technique
People more and more are accustomed to using vacuum-packed food or clothing now, this mode can make food fresh-keeping for a long time, and nondiscolouring is spoiled, and it is little that clothing is stored volume, and not mouldy round insect bite of moisture-sensitive etc., but this vacuum packaging is directly implemented by producer mostly, belongs to disposable use, after people buy, unpacking is promptly useless, if food is not eaten up or is thought and again clothing stored, can only it be tightened with hand push-through packs bag, effect is not satisfactory.Several home-use vacuum pumping devices are arranged in the market, and as evacuator, vacuum collection article bag etc., evacuator is a mechanical device, price height, complicated operation; Vacuum collection article bag is not too perfect owing to structure, the phenomenon that on the link of bleeding, often leaks air, and can only preserve clothing, can not store food, so all can not satisfy the growing life requirement of people.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provides a kind of and reuses, and is easy to operate, and good airproof performance is cheap, and the vacuum seal that especially is fit to family's use is shut up.
The purpose of this utility model is achieved through the following technical solutions: it has the envelope body, be provided with vent in the envelope body, seal the external briquetting that is provided with, top at the envelope body is provided with top cover, its special way is, be provided with mitre velve in vent, the conical surface of mitre velve matches with the inner conical surface of envelope body, is provided with interstage sleeve on the envelope body of mitre velve rear side.
The utility model has adopted movable mitre velve structure, therefore after being evacuated in the article bag, under the effect of positive and negative pressure, mitre velve can hold out against the closed vent hole automatically, overcome the shortcoming that existing collection bag needs the hand-tight make-up draught excluder to seal, easy to use, and the conical surface seal effect is stronger than existing plane sealing effect, can avoid gas leak phenomenon well.
Below in conjunction with the drawings and specific embodiments, the utility model is explained further.
Description of drawings:
Fig. 1-a kind of structural representation of the present utility model;
Fig. 2-another kind of structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 envelope body, 2 vents, 3 top covers, 4 briquettings, 5 mitre velves, 6 interstage sleeves, 7 pressure rings, 8 filter screens, 9 fore-sets, 10 package bags, 11 seal washers.
Specific embodiment
With reference to figure 1, envelope body 1 is made hollow type, and vent 2 is left at the center, the envelope body 1 outer briquetting 4 that is provided with, briquetting 4 can be for being threaded with envelope body 1, also can be clamping, grafting or the like,, in the vent 2 of envelope body 1, mitre velve 5 is set as long as the packing body sealing and fixing that can will put into is between the two lived, the conical surface of mitre velve 5 matches with the inner conical surface of envelope body 1, on the envelope body 1 of mitre velve 5 rear sides, fixedly install interstage sleeve 6, lose, top cover 3 is installed on the top of envelope body 1 to prevent that mitre velve 5 from dropping out.Whole vacuum seal is shut up and all can be adopted rubber-plastics material to make.
The utility model is applicable on any soft wrapping bag, is example with the plastic packaging bag, opens an aperture in package bag 10, vacuum seal is shut up put into the hole, and chucking briquetting 4 makes the aperture limit of package bag 10 enclose fixing seal between envelope body 1 and briquetting 4.During use, pack in the package bag food or clothing, seal sack, open the top cover 3 that vacuum seal is shut up then, insert pump bowl (or dust collector suction pipe), outwards bleed, air is discharged by vent 2 in the bag, and after treating to be evacuated in the bag, mitre velve 5 pushes against vent 2 automatically under external air pressure, extract pump bowl, lid presses closer and covers 3 and get final product.Also can set up a seal washer 11 in top cover 3 inboards, to strengthen sealing effect.If want to take out bag interior article, as long as open sack, mitre velve 5 unclamps automatically at this moment, can be to vacuum seal any damage of having shut up, and package bag and vacuum seal are shut up and all can repeatedly be recycled.
The long period storing products in order to prevent gas leakage, can be provided with fore-set 9 (with reference to figure 2) on top cover 3 if desired, and the other end of fore-set 9 is against on the mitre velve 5, so just can guarantee that mitre velve 5 is not loosening for a long time, plays the better seal effect.
In addition, on the bottom of envelope body 1, also can be provided with pressure ring 7, between pressure ring 7 and envelope body 1, fixedly install filter screen 8, when preventing from outwards to bleed article in the bag be released.This kind structure is applicable to granule food such as storing rice, mung bean.
