In order to realize the above purpose, the utility model discloses a technical scheme be provide a storage bag air valve leak protection structure, it includes:
the bag body comprises a bag membrane, the bag membrane is connected with the air valve seat, the bag membrane and the air valve seat form a multi-ring heat sealing ring at intervals, and an evacuation ring is formed between the multi-ring heat sealing; the air tightness is formed by improving the heat sealing of the air valve seat surface and the bag film sheet by means of the air avoiding ring.
In one or more embodiments of the present invention, the air-avoiding ring is attached to the deformable gas space formed by the heating mold when the surface of the air valve seat is uneven, so as to achieve tight adhesion between the heat sealing ring and the surface of the air valve seat.
In one or more embodiments of the present invention, the bag body is provided with a double zipper, two ends of the double zipper enter into the corner seal, and a longitudinal seal and a transverse seal located at the edge.
In one or more embodiments of the present invention, the number of the space-avoiding rings is plural.
Compared with the prior art, the utility model the effect that exists is:
because the utility model adopts the above scheme, the structure is simple and compact, the valve body seat and the bag membrane are heat sealed, so as to effectively prevent the air leakage of the bag body; therefore, the device has excellent technical, practical and economic performance.
