3., safe in utilization, closed reliable: blocking-up gas leakage effect is apparently higher than other inflation closing device, and air pressure inside is high more, and closure effect is obvious more, and closure effect can keep more than 1 year.

In addition, the invention process is simple, makes simple and easyly, and formed product is solid durable, easy to use, and the market space is wide, has high surcharge.

Embodiment

The present invention, can specifically be implemented by the combination of corresponding module as a technological scheme.

Below, in conjunction with an embodiment and accompanying drawing, the invention will be further described:

Fig. 1 is that the solid of one embodiment of the invention is partly cutd open figure.

Among Fig. 1, inflating closer peripheral module and center module two-part are formed; Wherein: peripheral module is the main body part of whole inflating closer, comprises inflation inlet 1, core 2, interior flap 3, capsule pipe 4, suction port 5, capsule tube cavity 7 and outer flap 8 these seven parts; Center module is the core component of inflating closer, only 6 one parts of slide block.

The distribution rule of peripheral module each several part is: inflation inlet 1 is positioned at the central position of whole inflating closer, inwardly is communicated with capsule tube cavity 7 and suction port 5; Peripheral structure is followed successively by outer flap 8, core 2, interior flap 3 and capsule pipe 4; Though outer flap and interior flap are not of uniform size, the wing constitutes the closed sucker of two clamping aeration vessel inwalls, rigid blocking-up gas communication to relatively.

Fig. 2 is the main manufacturing dimension schematic representation of embodiment.

Among Fig. 2, main manufacturing dimension is benchmark with air closer height 9, and the manufacturing dimension except other position core, the air-filled pore forms ratio values with reference to air closer height 9, shown in the table specific as follows:

Closer height 9	Outer flap diameter 16	Interior flap diameter 17	Core diameter 15	Capsule pipe diameter 12	Capsule tube cavity diameter 11	Capsule tube cavity height 14	Slide block height 10	Suction port diameter 13
Closer height 9	Outer flap diameter 16	Interior flap diameter 17	Core diameter 15	Capsule pipe diameter 12	Capsule tube cavity diameter 11	Capsule tube cavity height 14	Slide block height 10	Suction port diameter 13	H	0.67H	1.67H	0.27H	0.33H	0.17H	0.5H	0.33H	0.06H
