Between two adventitia 2a, 2b, also be provided with two superimposed inner membrance 1a, 1b up and down, and two inner membrances have identical width with two adventitias, the two side ends periphery of two inner membrances is heat-sealed line 3c, 3h heat-sealing bonding too, and two inner membrances are separated by many heat-sealing line 3e too.But the length of two inner membrances is shorter than two adventitias, and as Fig. 4 B, the top of two inner membrances is positioned at inflatable region and the end in the top of two adventitias; The bottom of two inner membrances is positioned at the gas storage district and is shorter than the bottom of two adventitias, and Fig. 4 A center line 33 is the bottom of two inner membrances.
All be provided with a reverse air-stopping valve in each air chamber of two adventitias, this reverse air-stopping valve comprises two inner membrance 1a, 1b that place between two adventitia 2a, the 2b.The intermembranous heat proof material 1c that is coated with in advance in two, its shape also claims heat-resisting joint as joint.Two inner membrances and heat proof material 1c all extend to the gas storage district from inflatable region.
Two inner membrance 1a and 1b are by ring-type heat-sealing line 3f heat-sealing bonding, this ring-type heat-sealing line 3f is located in the gas storage district, heat proof material 1c runs through the first heat-sealing line 3b and ring-type heat-sealing line 3f, and heat proof material 1c and the first heat-sealing line 3b intersection and between two inner membrances, form the first air intake 2e, heat proof material 1c and ring-type heat-sealing line 3f intersection and between two inner membrances, form the second air intake 2f.From the first air intake 2e to forming first gas passage the second air intake 2f.
In inflatable region 3a-3b, the inside of two adventitias is heat-sealed a 2c heat-sealing bonding with the outside of adjacent inner membrance respectively, and this heat seal point 2c preferably is positioned at the top end near two inner membrances.
Described gas storage district 3b-3d is filled with air and forms independently gas column 11, gas column comprises curved regions 11a and cylinder district 11b, shown in Fig. 4 B, curved regions is the zone that seals from the first heat-sealing line 3b to ring-type between the line 3f, and the cylinder district then is the following zone of ring-type heat-sealing line 3f.When the gas in the gas storage district is oppressed two inner membrances, in curved regions, form a plurality of fold 110 between two inner membrances; And in the cylinder district, two inner membrances are attached on a slice adventitia tightly and entirely.
When air seal 1 of the present invention is put on the air, gas at first enters along inflation road 9 from inflation inlet 12, in inflatable region, two adventitias are expanded and fill out intermembranously in the air course 9, two not engage mutually because of being coated with heat proof material 1c, and two adventitias and adjacent interior intermembranous bonded to each other because of being respectively equipped with heat seal point 2c, when air course is filled out in the expansion of two adventitias, nature is also outwards opened two inner membrances, thereby the self-opening first air intake 2e makes air admission gas storage district.In the time of between gas is by two inner membrance 1a, 1b in the first air intake 2e inflow gas storage district, because of the two interior intermembranous heat proof materials that are coated with do not engage two inner membrances mutually, make the second air intake 2f self-opening thus, gas charges into gas column 11 by this second air intake 2f, and then make gas column 11 inflations, because each gas column is inflation all, so whole air seal 1 is full of fully.
Curved regions 11a is the plane before inflation, along with constantly inflating to gas column, gas column becomes spheroidal gradient circular arc district by the plane gradually at curved regions 11a, because of from the plane to the circular arc, there being the shrinkage " π " of nature, shown in Fig. 4 C, so the interior adventitia of inflation rear curved surface district 11a produces many fold because of natural shrinkage, and after the inflation, inflatable region 3a-3b also produces many fold because of shrinkage.Although the compressing of the gas in the gas column 11 is positioned at two inner membrance 1a, the 1b of curved regions 11a and makes it can attach a slice adventitia 2a or 2b, thereby cover the first air intake 2e, but two inner membrance 1a, 1b of curved regions can't smoothly be attached at a slice adventitia 2a or 2b because of being formed with many fold 110, shown in Fig. 4 B, provide the finedraw of air inversion in the gas column.
But at the cylinder district of curved regions 11a downside 11b, gas column 11 is cylindric at 11b place, cylinder district, gas compressing in the gas column 11 is positioned at two inner membrance 1a, the 1b of cylinder district 11b, make two inner membrances be attached in a slice adventitia 2a or the 2b tightly and entirely, thereby cover the second air intake 2f and seal gas column 11, gas in the gas column 11 can't be leaked by fold 110 adverse currents that are positioned at curved regions 11a, thereby reach the effect of holding one's breath.
In Fig. 5 A and Fig. 5 B, 3f forms with heat-sealing means bonding two inner membrance 1a, 1b owing to ring-type heat-sealing line, so the thickness of ring-type heat-sealing line 3f makes the second air intake 2f and ring-type heat-sealing line 3f form high low head greater than the thickness of two inner membrance 1a and 1b.When gas column 11 inflations, gas compressing two inner membrance 1a, 1b in the gas column 11 are to cover the first air intake 2e and the second air intake 2f, thereby sealing gas column 11, gas in the gas column 11 can't be leaked by fold 110 adverse currents that are positioned at curved regions 11a, not only strengthen airtight effect, also prolonged the service life of air seal greatly.
The variation of first embodiment
Fig. 4 D is the variation of first embodiment of the invention, and its structure and Fig. 4 C difference are, are provided with heat- sealing line 4g and 4h among Fig. 4 D.In Fig. 4 D, also be provided with a pair of arcuation heat-sealing line 4g and heat-sealing line 4h on two inner membrance 1a and the 1b or on two inner membrance 1a and 1b and arbitrary adventitia 2a or the 2b, heat-sealing line 4g rises and opens in ring-type heat-sealing line 3f, the place, bottom that ends at the bottom of inner membrance or approach inner membrance.Between this a pair of arcuation heat-sealing line 4g and be formed with air conduct path 13 between two inner membrances, described heat-sealing line 4h makes the bottom of two inner membrances form gas port 14 between described a pair of arcuation heat-sealing line 4g.
In the present embodiment, with two inner membrances superimposed after, first heat-sealing ring-type heat-sealing line 3f, and then seal a pair of arcuation heat-sealing line 4g and heat-sealing line 4h.
Shown in Fig. 4 D, when to air seal 1 inflation, gas enters along inflation road 9 from inflation inlet 12, at first make the expansion of two adventitias and fill out air course 9, and two adventitias and adjacent interior intermembranous bonding mutually because of being respectively equipped with heat seal point 2c, intermembranously in two do not engage mutually because of being coated with heat proof material 1c, thus when air course is filled out in the expansion of two adventitias, nature is also outwards opened two inner membrances, thereby the self-opening first air intake 2e makes the curved regions 11a in the air admission gas storage district, and then opens the second air intake 2f again, make air along air conduct path 13, air extractor duct 14 charges into gas column 11, gas column is expanded and seal line 3b from first to swell.
Because of curved regions 11a is plane before inflation, along with continuous inflation, curved regions becomes spheroidal gradient circular arc district by the plane gradually, because of from the plane to the circular arc, there being the shrinkage " π " of nature, so the interior adventitia of inflation rear curved surface district 11a produces numerous fold because of natural shrinkage, and after the inflation, inflatable region 3a-3b also produces many fold because of natural shrinkage.
Behind the air admission second air intake 2f, the periphery of cylinder district 11b is a burnishing surface, no wrinkle.Because ring-type heat-sealing line 3f is with two inner membrance heat-sealing bonding, therefore not can with after two adventitias are superimposed just the operation of heat-sealing heat- sealing line 4g and 4h conflict mutually.Also because ring-type heat-sealing line 3f not with arbitrary adventitia 2a heat-sealing bonding, so after inflation, curved regions 11a is a gradient circular arc district, ring-type heat-sealing line 3f just is the bend line that is changed into the cylinder smooth surface by the circular arc inclined-plane, so 3f begins to be provided with heat- sealing line 4g and 4h from this ring-type heat-sealing line, purpose is when the gas column aerification, and air is oppressed two inner membrances in the gas column, and two inner membrances below ring-type heat-sealing line 3f are overlayed tightly in a slice adventitia.
In addition, for being called fold district 3a-3b-3f to the zone the heat-sealing line 3f again from heat-sealing line 3a to heat-sealing line 3b, this zone is the plane before inflation, and behind the inflation, the surface can produce the fold that nature shrinks, and fold is tightened naturally by air pressure.But after the inflation, there is not fold from the gas column below the ring-type heat-sealing line 3f, all no longer include fold on the adventitia promptly, in this zone, gas column forms the very smooth face of cylinder behind aerification, and heat-sealing line 3f, 4g, 4h are at the surperficial envelope trace of giving prominence to that forms of gas column, and gas can be suppressed above-mentioned envelope trace earlier when the gas column inner air pressure is big.At this moment, if stand in and see two inner membrances in the gas column, can find, gas is at first suppressed ring-type heat-sealing line 3f and heat-sealing line 4g, 4h, thereby the second air intake 2f, air conduct path 13 and air extractor duct 14 are closed, and then two inner membrances of compacting ring-type heat-sealing line 3f outlet area, thereby block back flow of gas all sidedly, reach and strengthen the air tight effect.
In the present invention, above-mentioned ring-type heat-sealing line 3f forms with heat-sealing means bonding two inner membrance 1a, 1b, also can be to form with heat-sealing means bonding a slice adventitia 2a or 2b, two inner membrances.Ring-type heat-sealing line 3f can be arranged at the intersection of curved regions 11a and cylinder district 11b, or it is interior or be arranged in the curved regions 11a to be arranged at cylinder district 11b.
In the present invention, remove in the inflation road 9 can inflate external, but also water-filling gas mixture or liquid thus, can be taken in gas or air-water mixture or liquid in the gas column, liquid is through freezing and form icicle with as the refrigeration mediator.
