[0002] Sweet potato stems and leaves are rich in nutrients such as protein, vitamins, dietary fiber, minerals, etc. They have multiple health functions such as anti-oxidation and blood lipid regulation, and can be used as leafy vegetables and feed sources.

[0003] The cycle of collecting, storing, transporting and selling sweet potato stems and leaves is relatively long. During this process, the sweet potato stems and leaves need to be preserved. At this time, fresh-keeping bags are needed. Currently, fresh-keeping bags used for sweet potato stems and leaves are divided into breathable and sealed bags. Currently, the sealed fresh-keeping bags are ziplock sealed fresh-keeping bags. Through the sealing setting, the sweet potato stems and leaves are prevented from contacting with the outside air, thereby extending the storage time of the sweet potato stems and leaves.

[0004] However, there is still a lot of air inside the ziplock sealed fresh-keeping bag mentioned above. After a long storage time, the humidity around the sweet potato stems and leaves will be high, which will easily cause the sweet potato stems and leaves to rot and deteriorate, thereby reducing the storage time of the lotus root. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a fresh-keeping bag for packaging sweet potato stems and leaves for vegetables, so as to solve the technical problems mentioned in the above background technology.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1

[0035] A fresh-keeping bag for packaging sweet potato stems and leaves for vegetables, such as Figure 1 - Figure 6 As shown, the fresh-keeping bag comprises a main body 1 and a concave-convex clip chain 2. The concave-convex clip chain 2 is installed in multiple groups at equal intervals in the main body 1 of the fresh-keeping bag. At the same time, the number of the concave-convex clip chains 2 is ≥2. The multiple groups of concave-convex clip chains 2 can increase the sealing performance of the opening of the main body 1 of the fresh-keeping bag, and reduce the probability of accidental air leakage. In addition, two magnetic strips 3 that attract each other are installed on the outer walls of both sides of the main body 1 of the fresh-keeping bag, so that in the process of sealing the opening of the main body 1 of the fresh-keeping bag, the two magnetic strips 3 are magnetically attracted to each other, which further increases the sealing performance and fixity of the main body 1 of the fresh-keeping bag after closing, further prevents the accident of air leakage, and in the fresh-keeping bag A one-way valve 4 is installed on the outer wall of the main body 1. Because the fresh-keeping bag main body 1 can be sealed under the action of the concave-convex clip chain 2, and the one-way valve 4 is set, the operator can evacuate the fresh-keeping bag main body 1 through the air pump and the one-way valve 4 to reduce the air content in the fresh-keeping bag main body 1, making the fresh-keeping bag main body 1 more convenient to use, and the end of the one-way valve 4 located in the fresh-keeping bag main body 1 is provided with an exhaust port 5, so that the air in the fresh-keeping bag main body 1 flows outward through the exhaust port 5 and the one-way valve 4, effectively reducing the probability of damage to the sweet potato stems and leaves, and effectively extending the storage time of the sweet potato stems and leaves;

[0036] Specifically, a rubber pad 7 connected to the one-way valve 4 is fixedly installed on the inner wall of the fresh-keeping bag main body 1, and the rubber pad 7 is also fixedly connected to the one-way valve 4. The setting of the rubber pad 7 increases the distance between the sweet potato stems and leaves and the exhaust port 5, effectively reducing the probability that the exhaust port 5 is blocked by the sweet potato stems and leaves. At the same time, an air guide port 8 communicated with the exhaust port 5 is opened in the middle of the rubber pad 7, so that the air in the fresh-keeping bag main body 1 can enter the exhaust port 5 through the air guide port 8. At the same time, an air guide groove 9 communicated with the air guide port 8 is opened on the outer wall of the rubber pad 7 away from the one-way valve 4. As a result, when the sweet potato stems and leaves block the air guide port 8, the air in the fresh-keeping bag main body 1 can still enter the air guide port 8 through the air guide groove 9, further ensuring that the operator can smoothly perform vacuum processing on the fresh-keeping bag main body 1, and because the opening of the air guide groove 9 is designed to open outward, the opening of the air guide groove 9 is relatively large, ensuring that the gas can pass through the air guide groove 9 smoothly.

[0037] See also Figure 2 - Figure 6Because the outer wall of the rubber pad 7 is fixedly connected to the inner wall of the fresh-keeping bag body 1, the position of the rubber pad 7 in the fresh-keeping bag body 1 can be guaranteed, ensuring the position fixity of the rubber pad 7 when in use. At the same time, a plurality of air guide grooves 9 are opened at equal angles on the outer wall of the other side of the outer wall of the rubber pad 7. The setting of multiple groups of air guide grooves 9 further ensures that the air in the fresh-keeping bag body 1 can flow into the air guide port 8, avoiding the inability to perform the vacuum pumping work after one air guide groove 9 is covered, further ensuring that the vacuum pumping work can be performed smoothly. At the same time, the outer wall corners of the rubber pad 7 and the opening corners of the air guide groove 9 are both designed with arc-shaped rounded corners, making the outer wall corners of the rubber pad 7 and the opening corners of the air guide groove 9 relatively smooth, reducing the probability of scratching the sweet potato stems and leaves after being placed in the fresh-keeping bag body 1.

[0038] See also Figure 3 - Figure 6 The outer wall of the rubber pad 7 is provided with a ventilation mechanism connected to the air guide port 8, and the ventilation mechanism is composed of an expansion groove 10 and a long groove 11, wherein the long groove 11 is provided with a plurality of equal angles on the outer wall of one side of the rubber pad 7 close to the one-way valve 4, and the long groove 11 is designed as a rectangular groove, and the top of the long groove 11 is connected to the air guide groove 9, and the end of the long groove 11 is connected to the air guide port 8, so that the air in the fresh-keeping bag body 1 can also be transmitted to the air guide port 8 through the long groove 11, so that after the opening of the air guide port 8 is covered, the air inside the fresh-keeping bag body 1 can still enter the air guide port 8 through multiple positions, and the expansion groove 10 is installed at an equal angle on the side wall of the rubber pad 7, and the expansion groove 10 is connected to the long groove 11. The groove 11 is connected with the air guide groove 9, so that even if the air guide groove 9 is blocked, the expansion groove 10 on the side wall of the rubber pad 7 can guide the air, causing the air to enter the air guide groove 9 and the long groove 11 through the expansion groove 10 on the side wall of the rubber pad 7, further ensuring that the air in the fresh-keeping bag body 1 can be smoothly extracted, and the expansion groove 10 and the long groove 11 both penetrate the rubber pad 7, ensuring that the expansion groove 10 and the long groove 11 have enough air for air to pass through, and at the same time, the diameter of the air guide port 8 is smaller than the diameter of the exhaust port 5, so that even if the air guide port 8 and the air guide groove 9 are blocked by the stems and leaves of sweet potato, the air inside the fresh-keeping bag body 1 can directly enter the exhaust port 5 through the long groove 11.

[0039] See also Figure 3 - Figure 6 The width of the expansion slot 10 is greater than the width of the air guide slot 9 and the width of the long slot 11, so that the expansion slot 10 has a sufficient size to guide air into the air guide slot 9 and the long slot 11. At the same time, because the width of the long slot 11 is smaller than the diameter of the sweet potato stem, it is very difficult for the sweet potato stem to enter the long slot 11, thereby ensuring that the long slot 11 completely blocks all the long slots 11 and prevents the gas from being discharged.

[0040] Embodiment 2

[0041] A fresh-keeping bag for packaging sweet potato stems and leaves for vegetables, such as Figure 1 - Figure 7 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts will not be repeated here. The difference is that an expansion port 12 is provided on the outer wall of the one-way valve 4 where the exhaust port 5 is provided, and the diameter of the outer end opening of the expansion port 12 is larger than the diameter of the exhaust port 5, so that the air passing through the long groove 11 can directly enter the exhaust port 5 through the expansion port 12, and because the expansion port 12 is concave toward the inner end of the exhaust port 5, and the diameter of the air guide port 8 is smaller than the diameter of the exhaust port 5, the stems and leaves of the sweet potato will not enter the position of the expansion port 12, thereby further ensuring the smooth progress of the vacuum extraction work.

[0042] The working principle of the utility model is as follows: when it is necessary to store the sweet potato stems and leaves, first open the fresh-keeping bag main body 1, put the sweet potato stems and leaves into the fresh-keeping bag main body 1, then seal the opening of the fresh-keeping bag main body 1 through the concave-convex clip chain 2, during which the magnetic strips 3 will be mutually adsorbed, further increasing the sealing performance of the opening of the fresh-keeping bag main body 1, then rotate the sealing cover 6 to remove it, and then use an air pump to extract the air in the fresh-keeping bag main body 1 through the one-way valve 4, perform a vacuum treatment on the fresh-keeping bag main body 1, reduce the air content inside the fresh-keeping bag main body 1, and thus prolong the storage time of the sweet potato stems and leaves;

[0043] During the extraction process, the rubber pad 7 will block the sweet potato stems and leaves to prevent the sweet potato stems and leaves from blocking the exhaust port 5. During this process, if the sweet potato stems and leaves block the air guide port 8, the air inside the fresh-keeping bag body 1 can still enter the air guide port 8 through the air guide groove 9. If the position of the rubber pad 7 at the beginning of the air guide groove 9 is deformed or blocked by the sweet potato stems and leaves, the air inside the fresh-keeping bag body 1 can still enter the exhaust port 5 through the expansion groove 10 and the long groove 11 to ensure smooth extraction.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
