Abstract
The utility model relates to the improvement of the structure of packing valve bag of the isolating agent liquid in a spraying pot. The utility model is characterized in that the lower part of a spring seat of the valve head is provided with a connecting tube, and the lower end of the connecting tube is provided with a sealing convex body. An upper port of the bag body is sealed and integrated with the sealing convex body. The length of upper edge of the valve cover to the bottom face of the canned bag body is larger than the length of the upper edge of the valve cover to the upper edge of the convex body of the bottom face of a spraying pot body, and therefore, the utility model has the advantages of reasonable structure, steady assembly, convenient production and assembly, good impact resilient performance, long product life, high yield, etc.
Description
The utility model relates to a kind of structural improvement that is widely used as the miniaturised nebuliser (jar) that sprays air freshener, pesticide, extinguishing chemical and so on, but especially relates to a kind of structural improvement that is arranged at the packing bag valve of fluid partitioning in the aerosol can.
At present, the monobasic packing is adopted in the production of state's internal sprayer, pesticide more, promptly in tank body, do not establish packing inside bag, but liquid and the driving that desire is sprayed placed in the jar together with gas butane or propane, and it is caused the fog-spray nozzle ejection by the tube connector that is opened on the bottom.Because propane, butane are inflammable and explosive toxic gas, have leakage in whole process of production unavoidably.So, after butane, propane gas are full of the workshop, then the direct labor being damaged, and be absolutely unsafe, whole workshop will be an inflammable and explosive dangerous material workshop.Equally, this product also all has certain danger in storage, transportation.When spraying, also often carrying butane, propane gas secretly in addition, all unfavorable for environmental sanitation and safety.
For this reason, the someone uses the aerosol can of two-component packaging bag instead, and its structure is directly to be provided with packing bag valve or both closely to be provided with on the spring base of spray valve.Like this, it is installed in the aerosol can, and after being full of compressed air, after the bag valve of filling solution upwards shrinks about 10mm, bag soars with in fact having only a fulcrum and is hung in the tank body, along with carrying is moved or use, the bag in it is ceaselessly vibration thereupon also, long its firmness that influences of time one.Simultaneously, because the hypotelorism between valve and the bag valve need be proposed the inflation of lid back when can is inflated, also be unfavorable for production operation.In addition, the product such as miniature fire extinguisher needs horizontal or vertical direction freely to fall each once from two meters high in the relevant product of country detects.To this, the aerosol can of existing said structure is difficult to detection by relevant product because of its bag valve that is hung in jar mouthful easily breaks.
Goal of the invention of the present utility model provides a kind of rational in infrastructure, and assembling is firm, the aerosol can two-component packaging bag valve of good impact resistance.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: be provided with tube connector below described holder for valve spring, be provided with in the lower end of tube connector and seal convex body; Described bag upper port with seal the convex body involution and be integral; And the bottom surface length of the extremely canned back of valve gap upper limb bag is greater than the upper limb of valve gap upper limb to the tank body bottom surface convex body of spraying.Like this, the bag of depositing liquid is except upper port is fixing, especially also fit closely with the jar end of arcuation epirelief at the bottom of making bag, make it firmly to be combined into one with tank body all the time, become another stable lower fulcrum of bag below, thus can solve well because of carry move or use in bag vibration and even the powerful problem that influences its firmness that is caused of impacting.
Described holder for valve spring below is provided with the boss with tube connector upper end interference fit; Be provided with strengthening wing on the convex body sealing of tube connector lower end, and the height that seals convex body is greater than bag seal widths 4-6mm.The sealing of sealing with further raising and adjust bag up and down.
In order both to improve the steadiness that combines between bag and the tank body, avoid again connecting and closely be absorbed in the bag and influence the sealing strength that tube connector seals convex body and bag, through repetition test research, generally to be advisable than the long 3-8mm of upper limb of valve gap upper limb to the tank body bottom surface convex body of spraying in described valve gap upper limb to the bottom surface length of canned back bag.
Therefore, the utlity model has rational in infrastructurely, assembling is firm, produce easy to assembly, good impact resistance, life of product is long, characteristics such as yield rate height.
Accompanying drawing 1 is that the utility model is arranged on a kind of partial cutaway schematic in the tank body;
Accompanying drawing 2 is a kind of agent structure schematic diagrames in the utility model;
Accompanying drawing 3 is that tube connector seals the A of plush copper to enlarged diagram in the accompanying drawing 2.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model and structure are specifically described.
Bag 5 adopts the aluminum-plastic composite membrane thermoplastic to be bonded, and its bottom surface 13 is arcuation and sticks into one with two sides, and four jiaos is four triangular shape involution sheets 15.Described strengthening wing 12 that seals convex body 10, its both sides and tube connector 3 and play matrix 14 usefulness mould one injection mouldings and make (referring to accompanying drawing 1 and accompanying drawing 3), and make boss 8 interference fit of its openend and holder for valve spring 7 belows.In order to improve both bond strengths, can on described boss 8, be provided with bulge loop, 3 mouthfuls of ends of tube connector inboard is provided with corresponding grooves.Then, in the heat seal of special use mechanically, the upper end and the strengthening wing 12 thermoplastic involutions that seal convex body 10 and both sides of bag 5 are integral.And described holder for valve spring 7 inboard and go up and can valve gap 1 be set and the first-class member of spraying accordingly by prior art.
Usually, manufacturer can produce the utility model by batch by required specification, then by the producer of production spray, be placed in the tank body the utility model of slightly being longer than tank body is folding, utilizing inflation technology under the lid on the inflator, dried compressed air is injected tank inner chamber 4, make it to produce 3kg/cm
2Air pressure; Again required cleaning agent or agrochemical liquor high pressure are injected in the bag 5, the bottom and the tank body of the back bag 5 that expands firmly are combined into one, become another lower fulcrum of bag below, and make the air pressure in the jar increase to 6kg/cm
2About, thereby reached foregoing invention purpose of the present utility model.
Certainly, above-mentioned production stage also can integral body be finished on a streamline, directly makes the aerosol can of required safe, cleaning.
