Detailed ways

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 utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-4, an embodiment provided by the present invention: a vacuum fresh-keeping sealed bag with a suction valve seat, comprising an upper diaphragm 5, a lower diaphragm 6, a sealing zipper 1, a peripheral buckle and a single It is composed of a suction seat for the one-way valve. The suction seat for the one-way valve is composed of the upper cover 2 of the suction seat, the lower cover 4 of the suction seat and the one-way sealing air valve 3. The upper diaphragm 5 and the lower diaphragm 6 are sealed on three sides. connection, the other side is sealed and connected to the sealing zipper 1 to form a hollow plastic bag, the outer surface of the vacuum sealing bag film is smooth and the inner surface is covered with fine grooves, the lower cover 4 of the suction seat and the inner side of the upper film 5 Firmly bonded together, the one-way sealing gas valve 3 is located between the upper cover 2 of the suction seat and the lower cover 4 of the suction seat, and the cylindrical sealing surface of the middle part of the one-way sealing gas valve 3 is the same as the suction seat. The inner circular sealing surface of the lower cover 4 of the gas seat is an interference fit.

Specifically, when the upper diaphragm 5 and the lower diaphragm 6 are combined together, the micro-grooves are interlaced.

Specifically, the one-way sealing air valve 3 is a silicone one-way sealing air valve.

Specifically, one side of the upper diaphragm 5 has an opening, and the lower cover 4 of the air extraction seat is placed in the center of the opening.

Specifically, the edge of the one-way sealing air valve 3 is a sheet structure and is provided with exhaust holes.

Specifically, the upper cover 2 of the suction seat and the lower cover 4 of the suction seat are provided with buckles, and the upper cover 2 of the suction seat and the lower cover 4 of the suction seat are fastened together by the peripheral buckles.

Working principle: The electrical components appearing in this application are not connected to the power supply and control switch when in use. When in use, the sealing zipper 1 is sealed, and the vacuuming machine is placed in the middle of the upper cover 2 of the vacuuming seat. The negative pressure lifts the one-way sealing air valve 3, and the gap between the sealing surface of the one-way sealing air valve 3 and the sealing surface of the lower cover 4 of the suction seat forms an air flow channel, so that the air in the vacuum bag is evacuated to form a negative pressure. When the air extraction is completed, remove the vacuum machine, and the one-way sealing air valve 3 is instantly pressed down due to the action of atmospheric pressure, and the interference fit between the sealing surface of the lower cover 4 of the air extraction seat forms a reliable and lasting sealing effect.
