The specific embodiment

Following according to detailed description of the embodiment shown in the drawing as back:

Shown in Figure 1 is the block diagram of the utility model collecting bag, and an end that discloses collecting bag 100 among the figure is a sack 101, and end is edge sealing 104 in addition.Have the parallel strip of paper used for sealing 102,103 of wall scroll or two bar at sack 101 places, strip of paper used for sealing be above public rail with down female rail symmetry involution after and with the sack sealing of room 108, gas is no longer passed in and out by sack.Next has strip hot melt envelope line 106 on the edge sealing 104, this envelope line 106 constitutes the exhaust duct 107 in a narrow footpath with edge sealing 104, and seals the barrier line that line 106 also becomes exhaust duct 107 and room 108; Exhaust duct 107 1 ends are provided with drain pipe overflow pipe 105 again, the plasticity capping 7 that this drain pipe overflow pipe 105 more can be set up plastics valve nozzle 109 (as shown in Figure 2) and match, and end is provided with an exhaust pass 9 or drain valve 6 (as shown in Figure 2) at least in addition; Wherein, exhaust pass 9 is the little openings that are positioned on the

envelope line

106, and 107 of room 108 and exhaust ducts are ganged up mutually; And blow off valve 6 also is located on the envelope line 106, and room 108 and exhaust duct 107 are ganged up mutually.

Aforementioned drain valve 6 structures are made up of the

plastic foil

61,62 of two symmetries and the heat-resisting thin slice 63 that is folded between two plastic foil as shown in Figure 3, and drain valve 6 one ends after the combination are arrival end 64, and end is exit end 65 in addition.Again for drain valve 6 is combined with collecting bag 100, can melt the envelope line 106 that forms that pressurizes by aforementioned hot decides the face of bag up and down 100a, the 100b of collecting bag 100 and plastic foil 61, the 62 glue blows of drain valve 6, this envelope line 106 preferably is positioned near arrival end 64 places, because it is molten that arrival end 64 inside have up and down two heat-resisting thin slices 63 can not produce glue, so arrival end 64 just can involution, so blow off valve 6 can keep unimpeded to allow air pass through.

As shown in Figure 5, after the interior collecting bag that bedding and clothing 200 are arranged 100 is reeled, gases in the room 108 can be subjected to crowded and go into exhaust duct 107 via drain valve 6 or exhaust pass 9, discharged by drain pipe overflow pipe 105 (or plastics valve nozzle 109) via exhaust duct 107 backs, this can prevent that gas from no longer bleeding back in room 108 again.

The arrival end 64 of aforementioned drain valve 6 is to be positioned at room 108, and exit end 65 is to be positioned at exhaust duct 107, so at room 108 air pressure during greater than exhaust duct 107 air pressure (as Fig. 4), air can be entered in the blow off valve 6 by arrival end 64, and two

plastic foil

61,62 strut about making, and air can be imported in the exhaust duct 107 smoothly, just understand auto-closing until two ends, 64,65 air pressure balance final vacuum valves 6, recover as Fig. 3 state, and the blow off valve 6 after the closure makes very difficult generation of air bleed back on the contrary.

See also Fig. 6, for preventing that aforementioned air from being bled back in exhaust duct 107 by drain pipe overflow pipe 105, the powerful paster 8 of can fitting on drain pipe overflow pipe 105 just makes air not reflux after powerful paster 8 is with drain pipe overflow pipe 105 sealings, only makes air exhaustion opening Shi Caineng.Secondly, more can be as Fig. 2, shown in Figure 7, at drain pipe overflow pipe 105 a plastics valve nozzle 109 is set, the flange of valve nozzle can be consolidated drain pipe overflow pipe 108, and the disjunctor chassis 1091 of bottom surface can be fixing with the bag face of the going up 100a fusion of collecting bag, cover on the flange of plastics valve nozzle 109 in addition and reach closing function, avoid capping 7 to break away from plastics valve nozzles 9 backs again and lose, can extend a coupling link 71 at capping 7 root edges and be set on the plastics valve nozzle 9 by a plasticity capping 7.In addition, more can be as shown in Figure 8, with powerful paster 8 sealing labels on the flange of plastics valve nozzle 109 and reach the osed top effect.

To sum up statement, but the collecting bag of the utility model exhaust improved at practising the formula shortcoming, prevent after the collecting bag exhaust is finished that by this gas from bleeding back in bag, and reach splendid leak-stopping and the anti-function that bleeds back.
