Detailed Description

The following, with reference to the drawings and the detailed description, further description of the present invention is made:

The first embodiment is as follows:

Please refer to fig. 1-4, according to the embodiment of the present invention, a self-sealing bag capable of automatically exhausting comprises a bag body 1, one side of the bag body 1 is provided with an automatic exhaust mechanism 2, the automatic exhaust mechanism 2 comprises a connecting sheet 3, the connecting sheet 3 is fixed on the inner wall of the bag body 1, an exhaust pipe 4 is fixed at the middle part of the connecting sheet 3, the exhaust pipe 4 runs through the bag body 1, and the exhaust pipe 4 is connected with the bag body 1 in a sealing manner, the exhaust pipe 4 is located at one end inside the bag body 1 and is fixedly provided with a funnel 5, the output end of the funnel 5 is fixedly provided with two light and thin electrostatic films 6, the two ends of the light and thin electrostatic films 6 are fixedly bonded, and the middle part of the light and thin electrostatic films 6 are electrostatically adsorbed, and the length of the light and thin electrostatic films 6 is less.
