The specific embodiment

In the embodiment of Fig. 1 and Fig. 2, show, it is a kind of automatic waterer, promptly need not to connect any piped water supply system, we can use the plastic beverage tube 10 of a hard, can be transparent for instance, the sanitation and hygiene that supply water in order to guarantee be put into water in 12 li in the pocket of an elastomeric material, it is (as shown in Figure 1) before being unkitted full water, and its volume is obviously less than the volume of beverage cartridge 10.

See from Fig. 1 that as us before the filled with water, the length of sack 12 is about as much as high half of tube 10, its diameter is obviously than little (as shown in Figure 2) of a neck 14.Usually the diameter of the elasticity pocket of scalability and length are by the viscosity decision of beverage.

After filling water, soft bag 12 just is attached on the inwall of tube.

In this legend, soft bag 12 has an opening, on every side around an edge 16, repeatedly is buckled on the neck 14 and (sees Fig. 1 and Fig. 3).

For making soft bag 12 paste the inwall (Fig. 2) of beverage cartridge 10, in the process that is filled with water in bag 12, the air in the tube must be discharged.For this reason, at least will be in practical operation in a design hole (not marking among the figure), the optional position of beverage cartridge 10.

After filling water, tube is sealed up (see figure 3) by the stopper 20 of a known models.

The tube plug 20 of this known models have one by ratchet device by the channel shaped top 24 securing lateral margins 22 of tube neck, and a tube neck outer wall is covered by the edge 16 of soft bag 12.

Tube plug 20 comprises a central opening 26, breach by one stretch in the tube cylindrical object 28 around, the end of this cylindrical object 28 is by interior plug 30 sealings that comprise two edges 32,34 itself.The inwall of cylindrical object 28 is close at edge 32, and edge 34 is affixed on its outer wall.The interior plug 30 of cylinder 28 wall ends fixes with the evagination part 36 of this cylinder 28 thanks to the groove on the edge 34.

Central opening 26 is sealed by a disk 40.Stick on tube plug 20 outer field disks 40,, just can not stick again in case opened.Therefore, the beverage cartridge that quilt tears disk 40 off can not be used, because it does not have disk protection, prevents that any foreign object improperly from entering in the tube.

Obviously, at the bottom of central opening 26, cylindrical object 28 and the post plug 30 be with water-feed in coolant outlet pipe 42 cooperatings.Therefore after beverage cartridge was installed on the water-feed, the tube neck rotated (promptly with Fig. 1, Fig. 2 and opposite direction shown in Figure 3) downwards, and coolant outlet pipe 42 is inserted in the center breach 26.These water pipe 42 ends of inserting beverage cartridge are leak frees.Plug 30 in pipe end is pushed open, and interior plug is common and water pipe 42 ends constitute ratchet structure, just as the drawn part of with dashed lines among Fig. 3.Some openings 44 appear in water pipe 42 in tube, water flows out by these breach.Water pipe also be connected (among the figure not show) with an outside water cock.

After beverage cartridge was pulled out from water-feed, interior plug 30 was often got back to the original position of cylindrical object 28 ends, can still keep its leak tightness like this after beverage cartridge leaves water-feed.

Tube is sent to a washing and dress water center then.There, tube plug 20 and soft bag 12 are dropped, after tube cleans and finishes, again according to different embodiments, be filled with water preceding or be filled with water after mix new soft bag 12 and new tube plug, can guarantee the cleaning in the tube like this.

Therefore, use the water-feed beverage that provides and the beverage that is contained in the disposable bottle of the beverage cartridge of being furnished with soft bag 12 to meet hygienic requirements equally.

Fig. 4 and Fig. 4 a present is one and is furnished with and meets the beverage cartridge 10 that the present invention requires and the water-feed 50 of interior soft bag 12.On Fig. 4, we can see that soft bag filled beverage, and bag is filled with water and only accounts for about 1/4th of 10 volume Fig. 4 a on.During water supply, pocket is soft, and extraneous air can not enter in the bag by liquid, because pocket reverts to its initial small size gradually.So, water just can not contact with extraneous air, the liquid quality in the tube is played an Additional Protection effect yet.

The water that sack is 12 li is only discharged by its gravity.Yet if sack 12 is elastomeric materials, its elasticity produces a kind of slight pressure, can improve the stability that liquid is discharged.

So we notice: utilization the present invention, still can continue to use beverage cartridge and traditional bucket, and need not reequip original water-feed, and reduce the danger of water pollution significantly.In fact, in dress water process, some residues may be trapped in the tube after the cleaning, but do not have the effect that infects bacterium, and the gas of water service periphery can not enter in the supply water.

The existence of soft bag 12 has also limited the infringement to water service that may cause in the process that is filled with water.In fact use traditional water-filling method, we can pour the liquid of the undue surplus in the beverage cartridge that fills with in the water service into again.So, with existing device systems, contaminated beverage cartridge can pollute whole water supply tank, and has used the disposable soft bag just can this thing happens.

In the invention described above design-calculated mode, the unique transformation that will carry out the traditional water supply device is: to the beverage cartridge punching, buy cheap soft bag according to the embodiment of adopting on the other hand on the one hand.

In embodiment of the present invention shown in Figure 5, soft bag 60 connects the tube plug 62 of a sealing beverage cartridge (not having among Fig. 5 to indicate).

The upper wall 64 that this plug 62 includes a central opening 66, this opening by one to the soft bag 60 inner cylinder shape inner walls 68 that protrude around.Tube plug also comprise one with Fig. 3 in the similar outward flange 70 in edge 22 of the model of showing, promptly be used for carrying out the ratchet joint with the tube neck top of beverage cartridge.

It is legal that soft bag 60 edge of opening are used such as mounting method or hot glue, connects the medial surface of the upper wall 64 between cylinder-shaped sleeve 68 and outward flange 70.

A central plug 72 is used for soft bag 60 and fills with liquid rear enclosed center port 66, and tube plug 62 then is installed in a neck place.

Upper wall 64 comprises an air gate 74 at least, and it is between upper wall outward flange and the soft bag 60.The air between soft bag and beverage cartridge inwall can be discharged in this hole 74 after soft bag 60 fills with liquid.This hole 74 along with finding time of soft bag, that is to say when sack is positioned on the water-feed in the beverage supply process, also can allow the outer interior space of tube of the soft bag of air admission.

Fig. 6 changes embodiment according to one of Fig. 5 design-calculated.In this was a, soft bag 60 upper edges linked to each other with cylindrical inner sleeve 68.Central plug 72 has a cylindrical outward flange 76 that is used for by ratchet device and 68 cooperations of cylindrical inner sleeve.In this example, have on the outward flange 76 of central plug 72 one with cylinder shape inner wall 68 on the groove 80 of watt rib 82 interlocks.

Also have a centre opening 84 on the central plug 72, the cylindrical object 86 of (situation of describing as Fig. 3) one and is used for that the water supply pipe of water-feed is entered wherein in the inner embedding in edge.Cylindrical object 86 interior plug 88 identical with interior plug 30 among Fig. 3 by and that have a same function seals.

When beverage cartridge was installed on the water-feed, plug 88 was the same with Nei Sai 30 in this, separated with cylindrical object 86, and when tin when water-feed takes out, returned the closed circular cylindrical objects once more.But when beverage cartridge was pulled away water-feed, interior plug 88 (the interior plug 30 in Fig. 3) did not return and blocks cylindrical object 86 sometimes, and was trapped in the soft bag 60 that will be dropped.Since but soft bag will be dropped, so this function error can not cause any defective.

Now will the description of the present invention a kind of production method relevant with Fig. 7 and Fig. 8, it can utilize the stopper of traditional beverage cartridge, i.e. stopper identical, and need not on tube, to punch with the stopper described 20 among Fig. 3, so as when water filling air-out and introduce air when supplying water.

For this reason, the opening part of soft bag 90 (see figure 7)s is connected with the top 94 that a ring set 92 its medial surfaces are used to be attached to beverage cartridge 96, the medial surface of this ring set 92 has the groove 98 of an opening at least, and it both can lead to the inner space 100 between soft bag 90 and the tube inwall, also can lead to the tube outside.

Show in the legend, can be equipped with various groove, as 98 ' 1,98 ' 2 grades (referring to Fig. 8).

In soft bag 90 water filling processes, do not settle the sealing stopper.On the contrary, as described in Figure 3, in water supply process, stopper has been placed (Fig. 7 does not indicate).This plug portion ground obstruction extraneous air enters the interlayer between soft bag 90 and beverage cartridge.Yet stopper can the complete closed blocks air, so still allow the interlayer of soft bag 90 of air admission and beverage cartridge 96.But in the time of except water filling, the amount of this emptying gas is also little.Differing in size of air exhaustion amount but do not cause disadvantage, because water supply speed will be much more slowly than flooding rate.

In order to reduce groove 98 quantity or tangent plane, the water filling of soft bag 90 can be undertaken by the method that makes ring set 92 leave the neck top 94 of beverage cartridge 96.Under this condition, the air in the soft bag 90 outside beverage cartridges can emit from the slit of 92 of top 94 and ring sets when water filling.

No matter be the equipment of what embodiment, for the ease of the liquid supply in the water-feed, pressurization around be in the tube soft bag.

In device of the present invention shown in Fig. 9, Figure 10 and Figure 11, there is a sleeve pipe 112 stopper 110 inboards, and are similar with the sleeve pipe 68 in the embodiment device of showing among Fig. 6, and the sleeve pipe inner end has a groove 114 to cast on the soft bag 116 (seeing Figure 11).

For this reason, stopper can use polyethylene or polypropylene material, and has its bottom of a groove 114 fixing breach 118 ' 1 and 18 ' 2 is separately arranged, and groove edge has pore 120 ' 1 etc., equally also is stationary distribution.

Subsequently, this groove is immersed in the latex of fusing, so that engage, cast in, as shown in figure 11 with soft bag 116.

In this case, whole stopper and soft bag are all discardable.

In Figure 12, Figure 13 and Figure 14, stopper 122 comprises annulus 122 and middle body 134.Annulus has a sleeve pipe 124, and cannula tip has a groove 126, can hold in the mouth the crimping 128 of soft bag 130.

Crimping 128 is fixed with the ring set 132 of middle body cooperation by means of one in groove 126 ends, middle body 134 then have have one the outside sleeve 138, its end ridge 140 is close to crimping 128 with ring set 132, for making it stick on groove 126 bottoms, embed by a double wedge on the sleeve 138 144 when the middle body 134 of stopper stoppers annulus 122 centers 146 li of grooves interlock and be connected with annulus 122.

In this embodiment, sleeve pipe 124 end diameter are greater than the diameter of other parts, so that make an edge 150, form the required last fixed card of ring set 132.

Shown in Figure 12, the middle body 134 of stopper comprises a center groove 152, is similar to the groove 86 shown in Fig. 6, its inner bottom is a circular cone stage body 154, and effect is similar to the interior plug 88 among Fig. 6, that is to say, when beverage cartridge is pulled away water-feed, the transpiration of its prevention or confined liquid.

In these two examples, the section piece that this circular cone stage body 154 has some side cuts or sections in advance can stretch in the beverage cartridge for making water inlet pipe and water outlet pipe 42 (see figure 3)s.As shown in figure 13, cross section form radially in advance, promptly cross section 156 loop axis lines 160 compile to center-point 158.
