As shown in figure 3,31 one side of the vacuum compression bag is provided with unidirectional extraction valve 33, sack is provided with sealing strip
32。
Embodiment 3
As shown in fig. 6, the elastic sealing cover lower surface is provided with circular concave 13, it is around provided with circular boss
14.Lower surface of the present invention is the contact surface with vacuum compression bag.As shown in Figure 1, the elastic sealing cover side is provided with
Exhaust passage 15 is communicated with vacuum pump outlet nozzle 10.
Wherein, the boss is as shown in table 1 below from the difference in height of concave surface, and material hardness is all mutually 50 (shore A types)
It is all mutually 12mm with projection width, takes the vacuum compression bag of several 20cm*30cm sizes, and fills the half-full state of article, into
Row vacuumizes test 10 times, and counts it and vacuumize average time.
Table 1
| Difference in height (mm) | 0.5 | 0.8 | 1 | 3 | 10 | 15 | 20 | 30 |
| Pumpdown time (min) | 20 | 13 | 1.1 | 1 | 1 | 1.2 | 1.3 | 1.4 |
By upper table 1 it is found that when smaller difference in height, in vacuum, channel is easy inside the extraction valve of vacuum compression bag
It is squeezed by concave surface, pumping is unsmooth, and the time is longer, when especially less than 1mm.When difference in height is more than 1mm, pumpdown time, which has greatly, to be changed
Kind, when difference in height is more than 3mm, the pumpdown time is more satisfactory.Therefore, difference in height of the boss from concave surface is preferably
1mm-30mm, most preferably 1-3mm.
Embodiment 4
As shown in fig. 6, the elastic sealing cover lower surface is provided with circular concave 13, it is around provided with circular boss
14.Lower surface of the present invention is the contact surface with vacuum compression bag.
Wherein, difference in height 3mm of the boss of elastic sealing cover from concave surface, and material hardness is all mutually 50 (shore A
Type), the elastic sealing cover for taking projection width of different sizes is sample, using the vacuum compression bag of several 20cm*30cm sizes,
And the half-full state of article is filled, carries out vacuumizing test 10 times, and count it and vacuumize the number of failure.
Table 2
| Width (mm) | 0.5 | 1 | 1.5 | 3 | 5 | 10 | 15 | 20 |
| Lose number | 8 | 2 | 1 | 0 | 0 | 0 | 0 | 0 |
By upper table 2 it is found that when smaller projection width, when the later stage negative pressure vacuumized is larger, boss is easily deformed,
It causes gas leakage and vacuumizes failure, when especially width is less than 1mm.Therefore, the projection width of elastic sealing cover is preferably sized to
Advantageous effect is notable when 1mm-15mm, especially 3mm-15mm.
Embodiment 5
As shown in fig. 6, difference in height 2mm of the boss of elastic sealing cover from concave surface, and projection width is all mutually 12mm, is taken
The silicone elastomer sealing cover of different hardness size is sample, using the vacuum compression bag of several 20cm*30cm sizes, and is filled
The half-full state of article carries out vacuumizing test 10 times, and counts it and vacuumize average time.
Table 3
| Hardness (shore A types) | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 |
| Pumpdown time (min) | 13 | 2 | 1 | 1 | 1 | 1 | 1.5 | 6 |
As seen from the above table, when the hardness of silicone elastomer sealing cover is too small, silica gel is easily deformed gas leakage, and especially hardness is less than 20
When.When hardness is too big, sealing effect not with great difficulty gas leakage, when especially hardness is more than 70.Therefore, the hardness of silicone elastomer sealing cover
It is preferably sized to 20-70 (shore A types), advantageous effect is notable when especially hardness is 30-60 (shore A types).
The foregoing is merely illustrative of the preferred embodiments of the present invention, is to combine specific preferred embodiment to institute of the present invention
The further description of work is, and it cannot be said that the specific implementation of the present invention is confined to these explanations.All spirit in the present invention
With within principle made by all any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention.
