[0002] Vacuum compression bags are used to store down products such as down jackets and duvets to prevent moisture, mildew, moths, and odors, saving space. However, due to the special nature of down fabrics, the air permeability is poor. Currently, the air valve on the compression bag is located inside the bag, and the valve leaf is mostly flat. The air valve is low in height and the exhaust direction is single. The air valve is blocked by the fabric of the down product and the air outlet cannot be pumped, resulting in failure to completely vacuumize. Utility Model Content

[0006] A further improvement is that a clamping groove is provided on the inner wall of the connecting port of the valve disc, and a clamping protrusion is provided on the outer wall of the upper part of the column barrel, and the clamping protrusion is clamped in the clamping groove to connect the valve disc and the column barrel.

[0007] A further improvement is that the column is provided with a notch from the top downwardly to connect with the vent hole, so as to facilitate the installation and connection of the cartridge of the valve disc with the column, and can also be used as a side exhaust port.

[0008] A further improvement is that the support platform includes a ring platform, a center tube and connecting ribs, the ring platform is connected to the inner wall of the connecting port, the two ends of the spaced connecting ribs are respectively connected to the inner edge of the ring platform and the outer wall of the center tube, the connecting column in the center of the seal is clamped in the center tube, the sealing sheet is placed on the ring platform all around, and the holes between the connecting ribs connect the airflow on both sides of the valve disc.

[0009] A further improvement is that the air inlet holes on the peripheral wall of the bowl-shaped tray are long holes extending from the top to the bottom.

[0010] A further improvement is that connecting threads are respectively provided on the outer wall of the connecting port and the inner wall of the valve cover. Beneficial Effects

[0011] The air valve column and bowl-shaped tray components in the bag of the present application are nearly four times higher than those of ordinary air valve leaves. The arc surface of the bowl-shaped tray can stretch the down fabric and the air outlet holes of the air valve. The air outlet holes on the side and bottom of the air valve have various exhaust directions, allowing air to enter the exhaust port from different directions, effectively solving the problem of blocked holes and inability to draw air.

[0018] like Figures 1 to 6 As shown, the utility model includes a valve body 1, a sealing member 2 and a valve cover 3. The valve body includes a connection port 12 on a valve disc 11 to form an exhaust port. A support platform 13 is provided in the connection port 12. The support platform 13 is used to support the sealing member 2. The valve cover 3 is connected to the connection port 12. A pressure ring 31 is provided in the valve cover 3 to abut the upper surface of the sealing member 2. The valve body 1 includes a connecting column 14 below the valve disc 11. A clamping groove 18 is provided on the inner wall of the connection port 12 of the valve disc. A clamping protrusion 19 is provided on the upper outer wall of the column 14. The clamping protrusion 19 is clamped in the clamping groove 18 to connect the valve disc 11 with the column 14. A vent 15 is provided on the column 14. The bottom end of the column 14 is connected to the middle of a bowl-shaped tray 16. An air outlet 17 is provided on the bottom and the surrounding wall of the bowl-shaped tray 16. The air outlet 17 on the surrounding wall of the bowl-shaped tray 16 is a long strip hole opened from the top to the bottom.
