Description

Technical Field

[0001] The utility model relates to the technical field of air extraction valves, in particular to an air extraction valve for a vacuum compression bag. Background Art

[0002] In areas with heavy rainfall and high humidity, the storage of heavy clothing and quilts has always been a problem for people. Vacuum compression bags are widely used because of their waterproof, mildew-proof, and moisture-proof properties. Vacuum compression bags are mainly used to store quilts and various types of clothing. They work by extracting the air inside the quilts and clothing (just like a sponge shrinks when compressed), thereby reducing the volume. Atmospheric pressure then flattens the originally expanded quilts and other items, isolating them from the outside air to save space and achieve dust, mildew, moisture, and insect-proof properties.

[0003] Most vacuum compression bags on the market currently have a nozzle. To remove the air from the bag, a vacuum cleaner or manual vacuum pump is typically used. The nozzle typically consists of a base and a sealing cap. The base has an air intake chamber. To use, the sealing cap is opened and the vacuum pump is positioned toward the nozzle opening to release the air. Once the air is exhausted, the sealing cap must be tightened onto the nozzle immediately to prevent external air from flowing back into the bag. Deflating the bag is a tedious process and requires the use of a vacuum pump. The bag must then be sealed immediately after evacuation. Summary of the Invention

[0004] The utility model provides a vacuum compression bag exhaust valve to solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum compression bag degassing valve, comprising a base, a valve cover, and a sealing gasket, characterized in that: a baffle is fixedly connected to the top of the base, and the baffle is detachably connected to the valve cover; a first exhaust hole is provided in the inner cavity of the baffle at the top of the base; a sealing gasket is provided in the inner cavity of the baffle for unidirectional flow of gas from the first exhaust hole to one side of the valve cover; and a limiting plate is fixedly connected to the inner cavity of the valve cover.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model discloses a vacuum compression bag degassing valve, comprising a base 1, a valve cover 2, and a sealing gasket 3. A baffle 5 is fixedly connected to the top of the base 1, and the baffle 5 is detachably connected to the valve cover 2. A first exhaust hole 4 is provided in the inner cavity of the baffle 5 at the top of the base 1. The inner cavity of the baffle 5 is provided with a sealing gasket 3 for one-way flow of gas from the first exhaust hole 4 to the side of the valve cover 2. The inner cavity of the valve cover 2 is fixedly connected to a limit plate 10. The vacuum compression bag degassing valve does not require an air pump to evacuate air. The gas in the cavity to be exhausted is manually discharged from the air valve. Moreover, it does not need to be sealed immediately after the gas is exhausted. The operation is convenient and is conducive to promotion. By providing a baffle rod 14 in conjunction with the connecting column 6, the first exhaust hole 4 can be evenly separated to prevent larger debris such as cotton wool from entering the first exhaust hole 4 and blocking the first exhaust hole 4.

[0026] The top of the base 1 is fixedly connected to a fixing ring located in the inner cavity of the baffle 5 and with an inner diameter smaller than the outer diameter of the sealing gasket 3. The first exhaust hole 4 is located in the inner cavity part of the fixing ring. When the sealing gasket 3 is arranged in the inner cavity of the baffle 5, it is located between the fixing ring and the limit plate 10. Since the inner diameter of the fixing ring is smaller than the outer diameter of the sealing gasket 3, the sealing gasket 3 can seal the first exhaust hole 4.

[0027] The sealing gasket 3 is made of silicone material. When the vacuum compression bag is evacuated, the impact of the gas will lift the sealing gasket 3, so that the first exhaust hole 4 is opened and the gas is discharged from the exhaust valve. After the vacuum compression bag is evacuated, the pressure inside the cavity becomes low, and the external air pressure is higher than the internal air pressure of the cavity. The external air pressure presses the sealing gasket 3, so that the sealing gasket 3 blocks the first exhaust hole 4 again to prevent external gas from flowing back into the cavity of the vacuum compression bag.

[0028] Specifically, a blocking rod 14 is installed at the bottom of the base 1 and is distributed in a ring shape around the center of the first exhaust hole 4.

[0029] One end of the blocking rod 14 facing the center of the first exhaust hole 4 is connected to a connecting column 6 , and the blocking rod 14 cooperates with the connecting column 6 to evenly divide the first exhaust hole 4 .

[0030] In this embodiment, there are six baffle rods 14, and one end of the six baffle rods 14 is commonly connected to the connecting column 6, and separates the first exhaust hole 4, which can play an isolation role and prevent cotton wool, clothes and other items from being embedded in the first exhaust hole 4 and causing the first exhaust hole 4 to be blocked.

[0031] Specifically, a limiting hole 9 is provided on the connecting column 6, and the sealing gasket 3 is fixedly connected to one end thereof facing the base 1 with a connecting rod 7 extending into the limiting hole 9, and the end of the connecting rod 7 is fixedly connected to the limiting block 8, and the inner wall of the limiting hole 9 is formed with a stopper 15 for blocking the limiting block 8.

[0032] In this embodiment, the end of the limit block 8 away from the sealing gasket 3 is arc-shaped, the limit block 8 and the connecting rod 7 can move in the limit hole 9, and the stopper 15 can block the limit block 8 so that the limit block 8 is placed in the limit hole 9 without leaving the limit hole 9.

[0033] Specifically, a connecting ring 11 with internal threads is fixedly connected to the inner cavity of the valve cover 2 , and the baffle 5 is annular, and its outer wall has external threads that match the internal threads of the connecting ring 11 .

[0034] In this embodiment, the baffle 5 having external threads is threadedly connected to the connecting ring 11 having internal threads, so that the valve cover 2 and the base 1 are connected together.

[0035] Specifically, the second exhaust holes 12 are evenly formed on a side of the valve cover 2 away from the base 1 .

[0036] The limiting plate 10 is annular, and its outer diameter is smaller than the inner diameter of the connecting ring 11 . The second exhaust hole 12 is provided between the connecting ring 11 and the limiting plate 10 .

[0037] In this embodiment, the second exhaust holes 12 are cross-shaped as a whole, and at least six are provided. During the exhaust process, the gas can be discharged from the second exhaust holes 12 to the exhaust valve, which facilitates the discharge of the gas.

[0038] Specifically, anti-slip grooves 13 are formed on the outer wall of the valve cover 2 .

[0039] In this embodiment, grooves are evenly formed on the outer wall of the valve cover 2 . The arrangement of the grooves forms anti-slip grooves 13 on the outer wall of the valve cover 2 .

[0040] During use, during the process of venting the vacuum compression bag, the impact of the gas will push the sealing gasket 3 toward the valve cover 2, so that the first exhaust hole 4 is opened, and the gas is discharged through the first exhaust hole 4 and the second exhaust hole 12. After the vacuum compression bag is vented, the pressure inside its cavity becomes low, and the external air pressure is higher than the internal air pressure of the cavity. The external air pressure presses the sealing gasket 3, causing the sealing gasket 3 to block the first exhaust hole 4 again, preventing external gas from flowing back into the cavity of the vacuum compression bag.

[0041] To sum up, the vacuum compression bag degassing valve does not require an air pump to evacuate air. The gas in the cavity that needs to be exhausted is manually discharged from the valve. There is no need to seal it immediately after the gas is exhausted. It is easy to operate and conducive to promotion. By setting a baffle 14 in conjunction with the connecting column 6, the first exhaust hole 4 can be evenly separated to prevent larger debris such as cotton wool from entering the first exhaust hole 4 and blocking the first exhaust hole 4.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
