Described first diaphragm seal 21C and described second diaphragm seal 22C overlaps between the described first air chamber layer 101C of described inflation unit 11C and described second air chamber layer 102C.Described first diaphragm seal 21C and described second diaphragm seal 22C is the overlapped two thin layer flexible membranes be made of plastics.Preferably, described first diaphragm seal 21C and described second diaphragm seal 22C is identical two membranes.

Often described first diaphragm seal 21C and described second diaphragm seal 22C has a proximal edge, and it extends the entrance of the described charge valve 20C of described inflation unit 11C, and a distal edge, and it is inner that it extends to described inflation unit.Preferably, described first diaphragm seal 21C and the described proximal edge of the second diaphragm seal 22C and the border of distal edge are adjoined separately.

In the present embodiment, the proximal edge of described first diaphragm seal 21C and described first air chamber layer 101C bonding.Proximal edge and the described second air chamber layer 102C of described second diaphragm seal 22C are bonding.

Described non-return diaphragm seal 23C is overlapped in the near-end of described first diaphragm seal 21C and described second diaphragm seal 22C, to form a filling channel 24C between described first diaphragm seal 21C and described non-return diaphragm seal 23C, and form a non-return passage 25C between described non-return diaphragm seal 23C and described second diaphragm seal 22C.

Described filling channel 24C is aligned to for being filled with air to fill described inflation unit 11C to described inflatable chamber 12C, until by the air pressure in described inflatable chamber 12C, make the far-end of described first diaphragm seal 21C and described second diaphragm seal 22C overlapping and seal to close described filling channel 24C.According to this preferred embodiment, when having gas from when having air leak between described first diaphragm seal 21C and the far-end of described second diaphragm seal 22C, as illustrated in figs. 10 a and 10b, in described inflatable chamber, the air of 12 is guided and enters described non-return passage 25C, to produce supplementary air pressure, thus seal described filling channel 24C further, to compensate the deficiency of the sealing effectiveness of described first diaphragm seal 21C and described second diaphragm seal 22C.

Described filling channel 24C has two open ends, and one of them nearly open end is formed at the proximal edge of described first diaphragm seal 21C and described non-return diaphragm seal 23C.One of in addition open end far away extends to the distal edge of described first diaphragm seal 21C and described second diaphragm seal 22C, to be connected with described inflatable chamber 12C.Pressurized air can enter described inflatable chamber 12C by described filling channel 24C guiding.

It is worth mentioning that, after described inflation unit 11C is full of air, air pressure in described inflatable chamber 12C applies pressure to described first diaphragm seal 21C and described second diaphragm seal 22C, thus seal described first diaphragm seal 21C and described second diaphragm seal 22C distal edge, and seal the open end far away of described filling channel 24C.In addition, the far-end of described first diaphragm seal 21C and described second diaphragm seal 22C is sealed because of surface tension.

Described non-return diaphragm seal 23C is the thin layer flexible membrane be made of plastics.Preferably, described non-return diaphragm seal 23C, described first diaphragm seal 21C and described second diaphragm seal 22C are polyethylene (PE) film.In addition, often the thickness of described first air chamber layer 101C and described second air chamber layer 102C is greater than often described first diaphragm seal 21C, the thickness of described second diaphragm seal 22C and described non-return diaphragm seal 23C.

According to a preferred embodiment of the invention, the length of described non-return diaphragm seal 23C is less than the length of often described first diaphragm seal 21C and described second diaphragm seal 22C, thus when described non-return diaphragm seal 23C is overlapped in the near-end of described first diaphragm seal 21C and described second diaphragm seal 22C, the far-end of described first diaphragm seal 21C and described second diaphragm seal 22C overlaps.It is worth mentioning that, the length of described non-return diaphragm seal 23C is defined as the distance between the proximal edge of described non-return diaphragm seal 23C and distal edge.Often the length of described first diaphragm seal 21C and described second diaphragm seal 22C is defined as the distance between the proximal edge of described first diaphragm seal 21C and described second diaphragm seal 22C and distal edge.

Correspondingly, when air is filled with described non-return passage 25C in described open end, described non-return passage 25C is filled with air to produce supplementary air pressure, thus the described filling channel 24C further between sealing described first diaphragm seal 21C and described second diaphragm seal 22C.

It is worth mentioning that, when being inflated to described inflatable chamber 12C by described filling channel 24C, the air flow in described filling channel 24C is contrary with the air flow of described non-return passage 25C.Therefore, air can not be filled with described non-return passage 25C.When air reveals back described non-return passage 25C from described inflatable chamber 12C, air enters described non-return passage 25C and seals described filling channel 24C further to produce supplementary air pressure, thus prevents gas leakage.It is worth mentioning that, the air of leakage, before revealing from the nearly open end of described filling channel 24C, can flow to the open end far away of described non-return passage 25C, thus avoid air leak from the open end far away of described filling channel 24C.In addition, described non-return diaphragm seal 23C and described first diaphragm seal 21C is sealed to seal described filling channel 24C due to surface tension.

In order to form described charge valve 20C at described inflation unit 11C, described charge valve 20C also comprises one first sealed engagement place 201 to be bonded together by described first air chamber layer 101C and described first diaphragm seal 21C at the valve openings place of described inflation unit 11C, with one second sealed engagement place 202 described second air chamber layer 102C, described non-return diaphragm seal 23C and described second diaphragm seal 22C are bonded together at the valve openings place of described inflation unit 11C.

Correspondingly, the proximal edge of described first diaphragm seal 21C is bonded with described first air chamber layer 101C by described first sealed engagement place 201.The proximal edge of described second air chamber layer 102C and described second diaphragm seal 22C, the proximal edge of described non-return diaphragm seal 23C is bonded together by described second sealed engagement place 202C.Preferably, two apart from one another by sealed engagement place 201C be used for described first air chamber layer 101C and described first diaphragm seal 21C to bond, two apart from one another by the second sealed engagement place 202C be used for described second air chamber layer 102C, described non-return diaphragm seal 23C and described second diaphragm seal 22C.It is worth mentioning that, described first sealed engagement place 201C and described second sealed engagement place 202C can be hot-sealing line, also can be the heat-sealing of other shapes as crescent shape.In other words, the proximal edge of described first diaphragm seal 21C and described first air chamber layer 101C are by described sealed engagement place 201 heat-sealing.The proximal edge of described second air chamber layer 102C and described second diaphragm seal 22C, and the proximal edge of described non-return diaphragm seal 22 is by described second sealed engagement place 202C heat-sealing.

After remaining on described heat seal process, space is had between described first diaphragm seal 21C and described non-return diaphragm seal 23C, described charge valve 20C also comprises one first heat-resisting thing 26C, and it is formed between described first diaphragm seal 21C and described non-return diaphragm seal 23C to ensure the formation of described filling channel 24C.Described first heat-resisting thing 26C is used for preventing described first diaphragm seal 21C and described non-return diaphragm seal 23C to be pasted together completely after described heat seal process.

Particularly, described first heat-resisting thing 26C is arranged on the near side (ns) edge of described first diaphragm seal 21C and described non-return diaphragm seal 23C and is positioned at the valve openings place of described inflation unit 11C, thus ensures that the described near-end of described filling channel 24C is in open mode.

Same, after remaining on described heat seal process, space is had between described second diaphragm seal 22C and described non-return diaphragm seal 23C, described charge valve 20C also comprises one second heat-resisting thing 27C, and it is formed between described second diaphragm seal 22C and described non-return diaphragm seal 23C to ensure the formation of described non-return passage 25C.

Particularly, described second heat-resisting thing 27C is arranged on the distal edge edge of described second diaphragm seal 22C and described non-return diaphragm seal 23C, thus ensures that the described far-end of described non-return passage 25C is in open mode.It is worth mentioning that, the near-end of described non-return passage 25C is closed by described second sealed engagement place 202.

According to this preferred embodiment, described first heat-resisting thing 26C and described second heat-resisting thing 27C is two refractory layers, and it is coated in the desired location on each self-corresponding film, is pasted together to prevent film in described pad envelope process.Described first heat-resisting thing 26C extends described non-return diaphragm seal 23C near-end side, and towards described first diaphragm seal 21C.The far-end that described second heat-resisting thing 27C extends described non-return diaphragm seal 23C is positioned at opposite side, and towards described second diaphragm seal 22C, wherein said second heat-resisting thing 27C is not arranged on the opposite side of the near-end of described non-return diaphragm seal 23C, and the described near-end of described like this non-return passage 25C can be closed by described second sealed engagement place 202C.It is worth mentioning that, described second heat-resisting thing 27C not only avoid described non-return diaphragm seal 23C with state the second diaphragm seal 22C and be bonded together, to ensure that the described far-end of described non-return passage 25C is in open mode, and the effect strengthened between described non-return diaphragm seal 23C and described first diaphragm seal 21C, thus because surface tension is to close described filling channel 24C.

Described charge valve 20C also comprises two side direction sealed engagement place 203C, and it is that two the 3rd sealed engagement are sentenced described for bonding the first diaphragm seal 21C and described non-return diaphragm seal 23C, thus forms the sidewall of described filling channel 24C.The width of described filling channel 24C is defined by described two side direction sealed engagement 203C.Particularly, described two side direction sealed engagement place 203C are two inclination hot-sealing lines, thus the width of described filling channel 24C successively decreases from each described inflatable chamber of described valve openings.In other words, the nearly open end of described filling channel 24C be a larger open end its be connected with described valve openings, and the open end far away of described filling channel 24C is a cone-shaped open end and be communicated with described inflatable chamber 12C.The filling channel 24C of described taper avoids air to be leaked to described valve openings from described inflatable chamber 12C further.

Preferably, described lateral seal joint 203C extends to its distal edge from the proximal edge of described first diaphragm seal 21C and described second diaphragm seal 22C.Therefore, described lateral seal joint 203C is positioned at described first diaphragm seal 21C and described second diaphragm seal 22C proximal part and described non-return diaphragm seal 23C and is bonded together.Described lateral seal joint 203C is positioned at described first diaphragm seal 21C and described second diaphragm seal 22C distal portions and described first diaphragm seal 21C and described second diaphragm seal 22C and is bonded together.

Correspondingly, in order to inflate to described inflation unit 11C, the pin of pump is inserted into described inflation inlet 13C pressurized air to be filled with described filling channel 24C, and wherein the inflation direction of air is arrive open end far away from the nearly open end of described filling channel 24C.Described like this inflation unit 11C starts inflation.The air pressure of described inflatable chamber 12C increases thus struts described first air chamber layer 101C and described second air chamber layer 102C.Meanwhile, gas pressure, in described first diaphragm seal 21C and described second diaphragm seal 22C, particularly acts on the far-end of described first diaphragm seal 21C and described second diaphragm seal 22C.After described inflation unit 11C fills air completely, namely after arriving maximum loading, air pressure in described inflatable chamber 12C reaches enough to seal the far-end of described first diaphragm seal 21C and described second diaphragm seal 22C, with the open end described far away of filling channel 24C described in automatic-sealed.At this moment the pin of pump detaches described inflation inlet 13C.

When described first diaphragm seal 21C does not have together with complete involution with the far-end of described second diaphragm seal 22C, the air of described inflatable chamber 12C may be leaked to described filling channel 24C.In order to avoid air leak is to described filling channel 24C, described non-return diaphragm seal 23C and described first diaphragm seal 21C involution are to seal the open end far away of described filling channel 24C.Particularly, the airintake direction of described non-return passage 25C is contrary with the inflation direction of described filling channel 24C.In addition, when the described open end of described non-return passage 25C is opened, the open end described far away of described filling channel 24C is closed.Therefore, air enters from the described open end of described non-return passage 25C and is retained in described non-return passage 25C.

Described non-return passage 25C is filled by air, produces and supplement air pressure to seal described filling channel 24C further in described like this non-return passage 25C.Especially, the open end described far away of the described filling channel 24C between described first diaphragm seal 21C and described non-return diaphragm seal 23C is sealed.More specifically, the supplementary air pressure in described non-return passage 25C is higher, and the sealing effectiveness of described non-return diaphragm seal 23C is better.In other words, when air is revealed from described inflatable chamber 12C with the air pressure reducing described inflatable chamber 12C, air enters described non-return passage 25C to improve the air pressure of described non-return passage 25C.Therefore, the total gas pressure of described inflation pressure, namely the air pressure sum of described inflatable chamber 12C and described non-return passage 25C remains unchanged.Like this, the air entering described non-return passage 25C from described inflatable chamber 12C can enter the sealing effectiveness strengthening described filling channel 24C.
