Examples

With reference to the accompanying drawings 1-4, the air valve for the vacuum compression bag comprises an air valve body 1 and a soft gasket 2 which are matched with each other, wherein the gasket 2 is disc-shaped, a central rod 3 is arranged in the center of the gasket 2, the air valve body 1 is circular, a through hole 9 matched with the central rod 3 is formed in the center of the air valve body 1, a limiting bulge 4 is formed in the end portion 12 of the central rod 3, and a limiting step 5 matched with the limiting bulge 4 is formed in the inner wall of the through hole 9. This technical scheme has saved the lid, and one can reduce product cost, and two can reduce the thickness of product to reduce packaging cost, set up matched with pneumatic valve body 1 and soft gasket 2, the structure is simplified, directly bleeds, easy operation, the user also has no way to take out seal gasket 2, avoids the part to lose, has saved lid back pneumatic valve no longer has the arch, and it is very convenient when folding the bag, avoids automatic bag folding machine to produce the trouble. In the actual sale process, because the lid of current pneumatic valve is various, the consumer sometimes can not operate, some can even open the lid, take out the back to bleed again to seal gasket 2. The improved structure can directly exhaust air, the operation is simple, a consumer can not take out the gasket 2, and the loss of parts is avoided.

As shown in fig. 2, spacing arch 4 is the ring-convex, the side of spacing arch 4 is the inclined plane structure, the direction of inclined plane structure is tip 12 little, and root 11 is big, the minimum internal diameter of spacing step 5 is less than the maximum diameter of spacing arch 4, after convenient well core rod 3 stretched into through-hole 9, spacing arch 4 and spacing step 5 cooperation were spacing, and the user has no way to take out gasket 2, has avoided the part to lose. When bleeding, it is higher for the inside atmospheric pressure of air exhaust equipment in the compression bag, gasket 2 can the upward movement, if spacing step 5 does not keep off spacing arch 4, gasket 2 can break away from whole valve body, spacing arch 4 is spacing promptly to prevent that gasket 2 from deviating from with spacing step 5 cooperation to also can prevent that the user from extracting gasket 2 mistake when not using at ordinary times, even do not have the lid like this, gasket 2 also can not drop. The minimum inner diameter of the limiting step 5 is smaller than the maximum diameter of the limiting bulge 4, and the limiting step 5 can block the limiting bulge 4.

The air valve body 1 is provided with an upper plane 7 facing the outside of the bag body of the compression bag, the upper plane 7 is provided with a cavity 10 for accommodating the gasket 2, the gasket 2 is lower than the upper plane 7, the air valve is not protruded any more, the bag folding is very convenient, and the automatic bag folding machine is prevented from generating faults. The reverse side of the edge of the upper plane 7 is provided with a bag body contact surface 6 which is arranged in parallel. The thickness of the edge of the upper plane 7 is smaller than 5mm, and the height of the air valve body 1 exceeding the vacuum compression bag is reduced, so that the bag body is smoother, and the automatic bag folding machine is further prevented from generating faults.

The production process comprises the following steps: the first step is as follows: stamping a plum blossom-shaped air outlet structure on the film, as shown in figure 3; the second step is that: the air valve is welded at a high temperature at the air outlet structure of the upper bag body, and the contact surface 6 of the bag body is a welding surface. Compared with the original punching structure, the plum blossom-shaped air outlet structure reduces the processing procedure of punching sheets made of raw materials, and saves the production cost.
