DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the embodiments described are merely a part of the embodiments of the present utility model, not all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Referring to FIGS. 1-5, the present utility model discloses a vacuum sealed preservation bag with an evacuation valve seat, including two silica gel sheets 1. A first sealing strip 2 and a second sealing strip 3 are respectively arranged on the surfaces of the two silica gel sheets 1. The side of the first sealing strip 2 close to the second sealing strip 3 is provided with a horizontal groove 4. The side of the second sealing strip 3 close to the first sealing strip 2 is fixedly connected to a horizontal strip 5. A flap 6 is arranged on the surface of the second sealing strip 3. A buckle strip 7 is fixedly connected to the surface of the flap 6. The surface of the first sealing strip 2 is provided with a T-shaped groove 8. An evacuation valve body 9 is arranged on the surface of the silica gel sheet 1.

[0024] Specifically, the shape of the inner wall of the T-shaped groove 8 is matched with the shape of the buckle strip 7.

[0025] In this embodiment, it is convenient for the buckle strip 7 to be smoothly placed into the T-shaped groove 8 to enhance secondary airtightness.

[0026] Specifically, the opposite sides of the two silica gel sheets 1 are both provided with fine corrugations 10.

[0027] In this embodiment, it is convenient for air to circulate through gaps of the fine corrugations 10.

[0028] Specifically, the two silica gel sheets 1 are integrated.

[0029] In this embodiment, the airtightness between the two silica gel sheets 1 is enhanced, such that they are not easy to leak and damage during use.

[0030] Specifically, the shape of the horizontal strip 5 is matched with the shape of the inner wall of the horizontal groove 4.

[0031] In this embodiment, it is convenient for the horizontal bar 5 to be put into the horizontal groove 4, such that the airtightness is better.

[0032] Specifically, the buckle strip 7 is made of silica gel.

[0033] In this embodiment, the buckle strip 7 can be easily put into the T-shaped groove 8 by utilizing the flexibility of silica gel, without affecting the airtightness.

[0034] Specifically, the evacuation valve body 9 includes an extraction seat upper cover 901, an extraction seat lower cover 902 and a one-way sealing valve 903. The one-way sealing valve 903 is made of silica gel, has an edge that is of a sheet structure and is provided with many exhaust holes 904. The one-way sealing valve 903 is communicated with the inside of the silica gel sheet 1. The extraction seat upper cover 901 and an evacuation seat lower cover 902 are fastened together by the one-way sealing valve 903 through peripheral buckle positions.

[0035] In this embodiment, with the exhaust hole 904, it is convenient to discharge air, the air is evacuated through the one-way sealing valve 903, and then the one-way sealing valve 903 is sealed by buckle positions to prevent air intake.

[0036] The working principle and use process of the present utility model are as follows: When in use, an object that needs to be sealed is placed between the two silica gel sheets 1, and the first sealing strip 2 and the second sealing strip 3 are closely attached, such that the horizontal strip 5 is buckled into the horizontal groove 4. At this time, the two silica gel sheets 1 are well sealed, and the flap 6 is rotated to make the buckle strip 7 stuck into the T-shaped groove 8 to enhance secondary airtightness between the two silica gel sheets 1. In addition, an evacuation cylinder is arranged on the evacuation valve body 9 for evacuation, and the evacuation is completed when the two silica gel sheets 1 are compressed.

[0037] In summary, according to the vacuum sealed preservation bag with an evacuation valve seat, by arranging the silica gel sheet 1, the first sealing strip 2, the second sealing strip 3, the buckle strip 7 and the T-shaped groove 8, the problem that because the rib strips implement the sealing by mutual friction, they are easy to separate under the action of external force, which causes the air to enter the sealed bag, affecting the using effect of the sealed bag is solved.
