As a preferable scheme of the utility model, the front surface of the packaging bag body and the position corresponding to the plastic one-way exhaust valve are provided with fixing holes fixedly connected with the plastic one-way exhaust valve.
As the preferable scheme of the utility model, the plastic one-way exhaust valve and the sealing cover are designed to be detachable structures, and the plastic one-way exhaust valve and the sealing cover are connected in a threaded manner.
In a preferred embodiment of the present invention, the concave chute extends in a height direction of the bag body of the packaging bag.
As a preferable scheme of the present invention, the connection mode between the concave chute and the extrusion seal is sliding connection.
Compared with the prior art, the utility model has the beneficial effects that:
1. according to the waterproof packaging bag with the air exhaust opening at the top, the structure is simple and reasonable, the operation is convenient, the sealing effect is good, the waterproof packaging bag can be repeatedly used, and the use cost is saved.
2. According to the waterproof packaging bag with the air exhaust port at the top, when liquid is injected into the packaging bag body and stored, the primary and secondary sealing strips are closed to keep the sealing performance in the bag, external air is prevented from continuously entering the bag, then the two extrusion sealing strips move to the highest position of the liquid level under the action of the concave sliding groove and are closed under the magnetic attraction capacity of the two magnetic strips, and after the two extrusion sealing strips are closed, a user slowly pushes the extrusion sealing strips upwards to extrude redundant gas in the bag upwards, and finally the redundant gas is exhausted through the plastic one-way exhaust valve, so that the completely sealed state in the bag is realized, and the storage effect is improved.
3. According to the waterproof packaging bag with the air exhaust port at the top, the plastic one-way air exhaust valve for exhausting air is arranged on the bag body of the packaging bag, and when the air generated in the sealed bag reaches a certain pressure, the air can push the air exhaust valve plate from inside to outside and exhaust redundant air outwards; when the pressure in the bag is reduced to be not enough to jack the valve plate, the valve is automatically closed, and the plastic one-way exhaust valve is also provided with the sealing cover, so that the external air is thoroughly prevented from entering, and the sealing property is improved.
